(8) Coverage. Sections 1.410(b)-2 through 1.410(b)-10 provide rules relating to the minimum coverage requirements provided by section 410(b)(1).

(9) Church election. Section 1.410(d)-1 provides rules relating to the election by a church to have participation, vesting, funding, etc., provisions apply.

(c) Application of participation standards to certain plans—(1) General rule. Except as provided in subparagraph (2) of this paragraph, section 410 does not apply to—

(i) A governmental plan (within the meaning of section 414(d) and the regulations thereunder),

(ii) A church plan (within the meaning of section 414(e) and the regulations thereunder) which has not made the election provided by section 410(d) and the regulations thereunder,

(iii) A plan which has not provided for employer contributions at any time after September 2, 1974, and

A plan described in subparagraph (1) of this paragraph shall, for purposes of section 401(a), be treated as meeting the requirements of section 410 if such plan meets the coverage requirements resulting from the application of section 401(a)(3) as in effect on September 1, 1974. In applying the rules of that paragraph (d) to plans described in this paragraph (c) employees whose principal duties consist in supervising the work of other employees shall be treated as officers, shareholders, and highly compensated employees.

(d) Supersession. Section 11.410(a)-1 through 11.410(d)-1 inclusive, of the Temporary Income Tax Regulation under the Employee Retirement Income Security Act of 1974 are superseded by this section and §§ 1.410(a)-2 through 1.410(d)-1.

(a) Plans not in existence on January 1, 1974. Under section 1017(a) of the Employee Retirement Income Security Act of 1974, in the case of a plan which was not in existence on January 1, 1974, section 410 and the regulations thereunder apply for plan years beginning after September 2, 1974. See paragraph (c) of this section for time plan is considered in existence.

(b) Plans in existence on January 1, 1974. Under section 1017(b) of the Employee Retirement Income Security Act of 1974, in the case of a plan which was in existence on January 1, 1974, section 410 and the regulations thereunder apply for plan years beginning after December 31, 1975. See paragraph (c) of this section for time plan is considered to be in existence.

(c) Time of plan existence—(1) General rule. For purposes of this section, a plan is considered to be in existence on a particular day if—

(i) The plan on or before that day was reduced to writing and adopted by the employer (including, in the case of a corporate employer, formal approval by the employer's board of directors and, if required, shareholder), even though no amounts had been contributed under the plan as of such day, and

(ii) The plan was not terminated on or before that day.

(2) Collectively bargained plan. Notwithstanding subparagraph (1) of this paragraph, a plan described in section 413(a), relating to a plan maintained pursuant to a collective bargaining agreement, is considered to be in existence on a particular day if—

(i) On or before that day there is a legally enforceable agreement to establish such a plan signed by the employer, and

(ii) The employer contributions to be made to the plan are set forth in the agreement.

(3) Special rule. If a plan is considered to be in existence on January 1, 1974, under subparagraph (1) of this paragraph, any other plan with which such existing plan is merged or consolidated shall also be considered to be in existence on such date.

(d) Certain existing plans may elect new provisions—(1) In general. The plan administrator (as defined in section 414(g)) of a plan that was in existence on January 1, 1974, may elect to have the provisions of the Code relating to participation, vesting, funding, and form of benefit (as in effect from time to time) apply to a plan year selected by the plan year selected by the plan administrator which begins after September 2, 1974, but before the otherwise applicable effective dates determined under section 1017 (b) or (c), 1021, or 1024 of the Employee Retirement Income Security Act of 1974, and to all subsequent plan years. The provisions referred to are the amendments to the Code made by sections 1011, 1012, 1013, 1015, 1016(a) (1) through (11) and (13) through (27), 1021, and 1022(b) of the Employee Retirement Income Security Act of 1974.

(2) Election is irrevocable. Any election made under this paragraph, once made shall be irrevocable.

(3) Procedure and time for making election. An election under this paragraph shall be made by attaching a statement to either the annual return required under section 6058(a) (or an amended return) with respect to the plan which is filed for the first plan year for which the election is effective or to a written request for a determination letter relating to the qualification of the plan under section 401(a), 403(a), or 405(a) of the Code and, if trusteed, the exempt status under section 501(a) of the Code of a trust consituting a part of the plan. If the election is made with a written request for a determination letter, the election may be conditioned upon issuance of a favorable determination letter and will become irrevocable upon issuance of such letter. The statement shall indicate that the election is made under section 1017(d) of the Employee Retirement Income Security Act of 1974 and the first plan year for which the election is effective.

(e) Examples. The rules of this section are illustrated by the following examples:

(a) General rule. Except as provided by paragraph (b) or (c) of this section, a plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) if the plan requires, as a condition of participation in the plan, that an employee complete a period of service with the employer or employers maintaining the plan extending beyond the later of—

(1) Age 25. The date on which the employee attains the age of 25; or

(2) One year of service. The date on which the employee completes 1 year of service.

(b) Special rule for plan with 3-year 100 percent vesting. A plan which provides that after not more than 3 years of service each participant's right to his accrued benefit under the plan is completely nonforfeitable (within the meaning of section 411 and the regulations thereunder) at the time such benefit accrues satisfies the requirements of paragraph (a) of this section if the period of service required by the plan as a condition of participation does not extend beyond the later of—

(1) Age 25. The date on which the employee attains the age of 25; or

(2) Three years of service. The date on which the employee completes 3 years of service.

(c) Special rule for employees of certain educational institutions. A plan maintained exclusively for employees of an educational institution (as defined in section 170(b)(1)(A)(ii)) by an employer exempt from tax under section 501(a) which provides that after 1 year of service each participant's right to his accrued benefit under the plan is completely nonforfeitable (within the meaning of section 411 and the regulations thereunder) at the time such benefit accrues satisfies the requirements of paragraph (a) of this section if the period of service required by the plan as a condition of participation does not extend beyond the later of—

(1) Age 30. The date on which the employee attains the age of 30; or

(2) One year of service. The date on which the employee completes 1 year of service.

(d) Other conditions. Section 410(a), § 1.410(a)-4, and this section relate solely to age and service conditions and do not preclude a plan from establishing conditions, other than conditions relating to age or service, which must be satisfied by plan participants. For example, such provisions would not preclude a qualified plan from requiring, as a condition of participation, that an employee be employed within a specified job classification. See section 410(b) and the regulations thereunder for rules with respect to coverage of employees under qualified plans.

(e) Age and service requirements—(1) General rule. For purposes of applying the rules of this section, plan provisons may be treated as imposing age or service requirements even though the provisions do not specifically refer to age or service. Plan provisions which have the effect of requiring an age or service requirement with the employer or employers maintaing the plan will be treated as if they imposed an age or service requirement. In general, a plan under which an employee cannot participate unless he retires will impose an age and service requirement. However, a plan may provide benefits which supplement benefits provided for employees covered under a pension plan, as defined in section 3(2) of the Employee Retirement Income Security Act of 1974, satisfying the requirements of section 410(a)(1) without violating the age and service rules.

(2) Examples. The rules of this paragraph are illustrated by the following examples:

(a) [Reserved]

(b) Special rule for plan with 2-year 100 percent vesting. A plan which provides that after not more than 2 years of service each participant's right to his or her accrued benefit under the plan is completely nonforeitable (within the meaning of section 411 and the regulations thereunder) at the time such benefit accrues satisfies the requirements of paragraph (a) of this section if the period of service required by the plan as a condition of participation does not extend beyond the later of—

(1) [Reserved]

(2) Two years of service. The date on which the employee completes 2 years of service. For employees not described in § 1.411(a)-3T(e)(1), which describes employees with one hour of service in any plan year beginning after December 31, 1988, or later in the case of certain collectively bargained plans, the preceding sentence shall be applied by substituting “3 years of service” for “2 years of service”.

(a) Maximum age conditions—(1) General rule. A plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) if the plan excludes from participation (on the basis of age) an employee who has attained an age specified by the plan unless—

(i) The plan is a defined benefit plan or a target benefit plan, and

(ii) The employee begins employment with the employer after the employee has attained an age specified by the plan, which age is not more than 5 years before normal retirement age (within the meaning of section 411(a)(8) and § 1.411(a)-7.

(2) Examples. The rules provided by this paragraph are illustrated by the following examples:

(b) Time of participation—(1) General rule. A plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) unless under the plan any employee who has satisfied the applicable minimum age and service requirements specified in § 1.410(a)-3, and who is otherwise entitled to participate in the plan, commences participation in the plan no later than the earlier of—

(i) The first day of the first plan year beginning after the date on which such employee first satisfied such requirements, or

(ii) The date 6 months after the date on which he first satisfied such requirements,

(2) Examples. The rules provided by this paragraph are illustrated by the following examples:

(a) Year of service. For the rules relating to years of service under subparagraphs (A), (C), and (D) of section 410(a)(3), see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

Rules relating to a general rule for a year of service, hours of service, and maritime industries apply for purposes of section 410(a) and the regulations thereunder.

(b) Seasonal industries. For rules which relate to seasonal industries under section 410(a)(3)(B), see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefits plans.

(c) Breaks in service—(1) General rule. This paragraph provides rules with respect to breaks in service under section 410(a)(5). Except as provided in subparagraphs (2), (3), (4), and (5) of this paragraph, all of an employee's years of service with the employer or employers maintaining a plan are taken into account in computing his period of service under the plan for purposes of section 410(a)(1) and § 1.410(a)-3.

(2) Employees under 3-year 100 percent vesting schedule—( i) General rule. In the case of an employee who incurs a 1-year break in service under a plan which provides that after not more than 3 years of service, each participant's right to his accrued benefit under the plan is completely nonforfeitable (within the meaning of section 411 and the regulations thereunder) at the time such benefit accrues, the employee's service before the break in service is not required to be taken into account after the break in service in determining the employee's years of service under section 410(a)(1) and § 1.410(a)-3 if such employee has not satisfied such service requirement.

(ii) Example. The rules of this subparagraph are illustrated by the following example.

(3) One-year break in service—(i) In general. In computing the period of service of an employee who has incurred a 1-year break in service, for purposes of section 410(a)(1) and § 1.410(a)-3, a plan may disregard the employee's service before the break until the employee completes a year of service after such break in service.

(ii) Examples. The rules provided by this subparagraph are illustrated by the following examples.

(4) Nonvested participants—(i) General rule. In the case of a participant in a plan who does not have any nonforfeitable right under the plan to his employer-derived accrued benefit and who incurs a 1-year break in service, for purposes of section 410(a)(1) and § 1.410.(a)-3 the plan may disregard his years of service prior to such break if the number of his consecutive 1-year breaks in service equals or exceeds his aggregate number of years of service prior to such break. In the case of a plan using the elapsed time method described in Department of Labor regulations, the plan may disregard such years of service prior to such break if the period of severance is at least 1 year and the period of severance equals or exceeds the prior period of service, whether or not consecutive, completed before such period of severance. The plan may in computing such aggregate number of years of service prior to such break disregard any years of service which could have been disregarded under this subparagraph by reason of any prior break in service.

(ii) Examples. The rules of this subparagraph are illustrated by the following example:

(d) Special continuity rule for certain plans. For special rules for computing years of service in the case of a plan maintained by more than one employer, see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(a) In general. Under section 1017(f) (1) of the Employee retirement Income Security Act of 1974, a plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) if the rules of the plan relating to breaks in service are amended, and—

(1) Such amendment is effective after January 1, 1974, and before the date on which section 410 becomes applicable to the plan, and

(2) Under such amendment, any employee's participation in the plan commences at any date later than the later of—

(i) The date on which his participation would commence under the break in service rules of section 410(a)(5), or

(ii) The earliest date on which his participation would commence under the plan as in effect on or after January 1, 1974.

(b) Break in service rules. For purposes of paragraph (a), the term “break in service rules” means the rules provided by a plan relating to circumstances under which a period of an employee's service or plan participation is disregarded for purposes of determining his rights to participate in the plan, if under such rules such service is disregarded by reason of the employee's failure to complete a required period of service within a specified period of time.

(a) In general—(1) Introduction to elapsed time method of crediting service. (i) 29 CFR 2530.200b-2 sets forth the general method of crediting service for an employee. The general method is based upon the actual counting of hours of service during the applicable 12-consecutive-month computation period. The equivalencies set forth in 29 CFR 2530.200b-3 are also methods for crediting hours of service during computation periods. Under the general method and the equivalencies an employee receives a year's credit (in units of years of service or years of participation) for a computation period during which the employee is credited with a specified number of hours of service. In general, an employee's statutory entitlement with respect to eligibility to participate, vesting and benefit accrual is determined by totalling the number of years' credit to which an employee is entitled.

(ii) Under the alternative method set forth in this section, by contrast, an employee's statutory entitlement with respect to eligibility to participate, vesting and benefit accrual is not based upon the actual completion of a specified number of hours of service during a 12-consecutive-month period. Instead, such entitlement is determined generally with reference to the total period of time which elapses while the employee is employed (i.e., while the employment relationship exists) with the employer or employers maintaining the plan. The alternative method set forth in this section is designed to enable a plan to lessen the administrative burdens associated with the maintenance of records of an employee's hours of service by permitting each employee to be credited with his or her total period of service with the employer or employers maintaining the plan, irrespective of the actual hours of service completed in any 12-consecutive-month period.

(2) Overview of the operation of the elapsed time method. (i) Under the elapsed time method of crediting service, a plan is generally required to take into account the period of time which elapses while the employee is employed (i.e., while the employment relationship exists) with the employer or employers maintaining the plan, regardless of the actual number of hours he or she completes during such period. Under this alternative method of crediting service, an employee's service is required to be taken into account for purposes of eligibility to participate and vesting as of the date he or she first performs an hour of service within the meaning of 29 CFR 2530.200b-2 (a) (1) for the employer or employers maintaining the plan. Service is required to be taken into account for the period of time from the date the employee first performs such an hour of service until the date he or she severs from service with the employer or employers maintaining the plan.

(ii) The date the employee severs from service is the earlier of the date the employee quits, is discharged, retires or dies, or the first anniversary of the date the employee is absent from service for any other reason (e.g., disability, vacation, leave of absence, layoff, etc.). Thus, for example, if an employee quits, the severance from service date is the date the employee quits. On the other hand, if an employee is granted a leave of absence (and if no intervening event occurs), the severance from service date will occur one year after the date the employee was first absent on leave, and this one year of absence is required to be taken into account as service for the employer or employers maintaining the plan. Because the severance from service date occurs on the earlier of two possible dates (i.e., quit, discharge, retirement or death or the first anniversary of an absence from service for any other reason), a quit, discharge, retirement or death within the year after the beginning of an absence for any other reason results in an immediate severance from service. Thus, for example, if an employee dies at the end of a four-week absence resulting from illness, the severance from service date is the date of death, rather than the first anniversary date of the first day of absence for illness.

(iii) In addition, for purposes of eligibility to participate and vesting under the elapsed time method of crediting service, an employee who has severed from service by reason of a quit, discharge or retirement may be entitled to have a period of time of 12 months or less taken into account by the employer or employers maintaining the plan if the employee returns to service within a certain period of time and performs an hour of service within the meaning of 29 CFR 2530.200b-2 (a) (1). In general, the period of time during which the employee must return to service begins on the date the employee severs from service as a result of a quit, discharge or retirement and ends on the first anniversary of such date. However, if the employee is absent for any other reason (e.g., layoff) and then quits, is discharged or retires, the period of time during which the employee may return and receive credit begins on the severance from service date and ends one year after the first day of absence (e.g., first day of layoff). As a result of the operation of these rules, a severance from service (e.g., a quit), or an absence (e.g., layoff) followed by a severance from service, never results in a period of time of more than one year being required to be taken into account after an employee severs from service or is absent from service.

(iv) For purposes of benefit accrual under the elapsed time method of crediting service, an employee is entitled to have his or her service taken into account from the date he or she begins to participate in the plan until the severance from service date. Periods of severance under any circumstances are not required to be taken into account. For example, a participant who is discharged on December 14, 1980 and rehired on October 14, 1981 is not required to be credited with the 10 month period of severance for benefit accrual purposes.

(3) Overview of certain concepts relating to the elapsed time method—(i) In general. The rules with respect to the elapsed time method of crediting service are based on certain concepts which are defined in paragraph (b) of this section. These concepts are applied in the substantive rules contained in paragraphs (c), (d), (e), (f) and (g) of this section. The purpose of this subparagraph is to summarize these concepts.

(ii) Employment commencement date. (A) A concept which is necessary in order to credit service accurately under any service crediting method is the establishment of a starting point for crediting service. The employment commencement date, which is the date on which an employee first performs an hour of service within the meaning of 29 CFR 2530.200b-2 (a) (1) for the employer or employers maintaining the plan, is used to establish the date upon which an employee must begin to receive credit for certain purposes (e.g., eligibility to participate and vesting).

(B) In order to credit accurately an employee's total service with an employer or employers maintaining the plan, a plan also may provide for an “adjusted” employment commencement date (i.e., a recalculation of the employment commencement date to reflect noncreditable periods of severance) or a reemployment commencement date as defined in paragraph (b) (3) of this section. Fundamentally, all three concepts rely upon the performance of an hour of service to provide a starting point for crediting service. One purpose of these three concepts is to enable plans to satisfy the requirements of this section in a variety of ways.

(C) The fundamental rule with respect to these concepts is that any plan provision is permissible so long as it satisfies the minimum standards. Thus, for example, although the rules of this section provide that credit must begin on the employment commencement date, a plan is permitted to “adjust” the employment commencement date to reflect periods of time for which service is not required to be credited. Similarly, a plan may wish to credit service under the elapsed time method as discrete periods of service and provide for a reemployment commencement date. Certain plans may wish to provide for both concepts, although it is not a requirement of this section that plans so provide.

(iii) Severance from service date. Another fundamental concept of the elapsed time method of crediting service is the severance from service date, which is defined as the earlier of the date on which an employee quits, retires, is discharged or dies, or the first anniversary of the first date of absence for any other reason. One purpose of the severance from service date is to provide the endpoint for crediting service under the elapsed time method. As a general proposition, service is credited from the employment commencement date (i.e., the starting point) until the severance from service date (i.e., the endpoint). A complementary purpose of the severance from service date is to establish the starting point for measuring a period of severance from service in order to determine a “break in service” (see paragraph (a)(3)(v) of this section). A third purpose of such date is to establish the starting point for measuring the period of time which may be required to be taken into account under the service spanning rules (see paragraph (a)(3)(vi) of this section).

(iv) Period of service. A third elapsed time concept is the use of the “period of service” rather than the “year of service” in determining service to be taken into account for purposes of eligibility to participate, vesting and benefit accrual. For purposes of eligibility to participate and vesting, the period of service runs from the employment commencement date or reemployment commencement date until the severance from service date. For purposes of benefit accrual, a period of service runs from the date that a participant commences participation under the plan until the severance from service date. Because the endpoint of the period of service is marked by the severance from service date, an employee is credited with the period of time which runs during any absence from service (other than for reason of a quit, retirement, discharge or death) which is 12 months or less. Thus, for example, a three week absence for vacation is taken into account as part of a period of service and does not trigger a severance from service date.

(v) Period of severance. A period of severance begins on the severance from service date and ends when an employee returns to service with the employer or employers maintaining the plan. The purpose of the period of severance is to apply the statutory “break in service” rules to an elapsed time method of crediting service.

(vi) Service spanning. Under the elapsed time method of crediting service, a plan is required to credit periods of service and, under the service spanning rules, certain periods of severance of 12 months or less for purposes of eligibility to participate and vesting. Under the first service spanning rule, if an employee severs from service as a result of quit, discharge or retirement and then returns to service within 12 months, the period of severance is required to be taken into account. Also, a situation may arise in which an employee is absent from service for any reason other than quit, discharge, retirement or death and during the absence a quit, discharge or retirement occurs. The second service spanning rule provides in that set of circumstances that a plan is required to take into account the period of time between the severance from service date (i.e., the date of quit, discharge or retirement) and the first anniversary of the date on which the employee was first absent, if the employee returns to service on or before such first anniversary date.

(4) Organization and applicability. (i) The substantive rules for crediting service under the elapsed time method with respect to eligibility to participate are contained in paragraph (c), the rules with respect to vesting are contained in subparagraph (d), and the rules with respect to benefit accrual are contained in paragraph (e). The format of the rules is designed to enable a plan to use the elapsed time method of crediting service either for all purposes or for any one or combination of purposes under sections 410 and 411. Thus, for example, a plan may credit service for eligibility to participate purposes by the use of the general method of crediting service set forth in 29 CFR 2530.200b-2 or by the use of any of the equivalences set forth in 29 CFR 2530.200b-3, while the plan may credit service for vesting and benefit accrual purposes by the use of the elapsed time method of crediting service.

(ii) A plan using the elapsed time method of crediting service for one or more classifications of employees covered under the plan may use the general method of crediting service set forth in 29 CFR 2530.200b-2 or any of the equivalencies set forth in 29 CFR 2530.200b-3 for other classifications of employees, provided that such classifications are reasonable and are consistently applied. Thus, for example, a plan may provide that part-time employees are credited under the general method of crediting service set forth in 29 CFR 2530.200b-2 and full-time employees are credited under the elapsed time method. A classification, however, will not be deemed to be reasonable or consistently applied if such classification is designed with an intent to preclude an employee or employees from attaining his or her statutory entitlement with respect to eligibility to participate, vesting or benefit accrual. For example, a classification applied so that any full-time employee credited with less than 1,000 hours of service during a given 12-consecutive-month period would be considered part-time and subject to the general method of crediting service rather than the elapsed time method would not be reasonable.

(iii) Notwithstanding paragraph (a) (4) (i) and (ii) of this section, the use of the elapsed time method for some purposes or the use of the elapsed time method for some employees may, under certain circumstances, result in discrimination prohibited under section 401(a)(4), even though the use of the elapsed time method for such purposes, and for such employees, is permitted under this section.

(5) More than one employer plans. For special rules for computing years of service in the case of a plan maintained by more than one employer, see 29 CFR Part 2530 (Department of Labor regulations relating to minimum standards for employee pension benefit plans).

(b) Definitions—(1) Employment commencement date. For purposes of this section, the term “employment commencement date” shall mean the date on which the employee first performs an hour of service within the meaning of 29 CFR 2530.200b-2 (a)(1) for the employer or employers maintaining the plan.

(2) Severance from service date. For purposes of this section, a “severance from service” shall occur on the earlier of—

(i) The date on which an employee quits, retires, is discharged or dies; or

(ii) The first anniversary of the first date of a period in which an employee remains absent from service (with or without pay) with the employer or employers maintaining the plan for any reason other than quit, retirement, discharge or death, such as vacation, holiday, sickness, disability, leave of absence or layoff.

(3) Reemployment commencement date. For purposes of this section, the term “reemployment commencement date” shall mean the first date, following a period of severance from service which is not required to be taken into account under the service spanning rules in paragraphs (c)(2)(iii) and (d)(1)(iii) of this section, on which the employee performs an hour of service within the meaning of 29 CFR 2530.200b-2(a)(1) for the employer or employers maintaining the plan.

(4) Participation commencement date. For purposes of this section, the term “participation commencement date” shall mean the date a participant first commences participation under the plan.

(5) Period of severance. For purposes of this section, the term “period of severance” shall mean the period of time commencing on the severance from service date and ending on the date on which the employee again performs an hour of service within the meaning of 29 CFR 2530.200b-2(a)(1) for an employer or employers maintaining the plan.

(6) Period of service—(i) General rule. For purposes of this section, the term “period of service” shall mean a period of service commencing on the employee's employment commencement date or reemployment commencement date, whichever is applicable, and ending on the severance from service date.

(ii) Aggregation rule. Unless a plan provides in some manner for an “adjusted” employment commencement date or similar method of consolidating periods of service, periods of service shall be aggregated unless such periods may be disregarded under section 410(a)(5) or 411(a)(4).

(iii) Other federal law. Nothing in this section shall be construed to alter, amend, modify, invalidate, impair or supersede any law of the United States or any rule or regulation issued under such law. Thus, for example, nothing in this section shall be construed as denying an employee credit for a “period of service” if credit is required by a separate federal law. Furthermore, the nature and extent of such credit shall be determined under such law.

(c) Eligibility to participate—(1) General rule. For purposes of section 410(a)(1)(A), a plan generally may not require as a condition of participation in the plan that an employee complete a period of service with the employer or employers maintaining the plan extending beyond the later of—

(i) The date on which the employee attains the age of 25; or

(ii) The date on which the employee completes a one-year period of service. See the regulations under section 410(a) (relating to eligibility to participate).

(2) Determination of one-year period of service. (i) For purposes of determining the date on which an employee satisfies the service requirement for initial eligibility to participate under the plan, a plan using the elapsed time method of crediting service shall provide that an employee who completes the 1-year period of service requirement on the first anniversary of his employment commencement date satisfies the minimum service requirement as of such date. In the case of an employee who fails to complete a one-year period of service on the first anniversary of his employment commencement date, a plan which does not contain a provision permitted by section 410(a)(5)(D) (rule of parity) shall provide for the aggregation of periods of service so that a one-year period of service shall be completed as of the date the employee completes 12 months of service (30 days are deemed to be a month in the case of the aggregation of fractional months) or 365 days of service.

(ii) For purposes of section 410(a)(1)(B)(i), a “3-year period of service” shall be deemed to be “3 years of service.”

(iii) Service spanning rules. In determining a 1-year period of service for purposes of initial eligibility to participate and a period of service for purposes of retention of eligibility to participate, in addition to taking into account an employee's period of service, a plan shall take into account the following periods of severance—

(A) If an employee severs from service by reason of a quit, discharge or retirement and the employee then performs an hour of service within the meaning of 29 CFR 2530.200b-2(a)(1) within 12 months of the severance from service date, the plan is required to take into account the period of severance; and

(B) Notwithstanding paragraph (c)(2)(iii)(A) of this section, if an employee severs from service by reason of a quit, discharge or retirement during an absence from service of 12 months or less for any reason other than a quit, discharge, retirement or death, and then performs an hour of service within the meaning of 29 CFR 2530.200b-2(a)(1) within 12 months of the date on which the employee was first absent from service, the plan is required to take into account the period of severance.

(iv) For purposes of determining an employee's retention of eligibility to participate in the plan, a plan shall take into account an employee's entire period of service unless certain periods of service may be disregarded under section 410(a)(5) of the Code.

(v) Example. Employee W, age 31, completed 6 months of service and was laid off. After 2 months of layoff, W quit. Five months later, W returned to service. For purposes of eligibility to participate, W was required to be credited with 13 months of service (8 months of service and 5 months of severance). If, on the other hand, W had not returned to service within the first 10 months of severance (i.e., within 12 months after the first day of layoff), W would be required to be credited with only 8 months of service.

(3) Entry date requirements—(i) General rule. For purposes of section 410(a)(4), it is necessary for a plan to provide that any employee who has satisfied the minimum age and service requirements, and who is otherwise entitled to participate in the plan, commences participation in the plan no later than the earlier of—

(A) The first day of the first plan year beginning after the date on which such employee satisfied such requirements, or

(B) The date six months after the date on which he satisfied such requirements, unless such employee was separated from service before the date referred to in subdivision (i) (A) or (B), whichever is applicable. See the regulations under section 410(a) (relating to eligibility to participate).

(ii) Separation from service—(A) Definition. For purposes of this section, the term “separated from service” includes a severance from service or an absence from service for any reason other than a quit, discharge, retirement or death, regardless of the duration of such absence. Accordingly, if an employee is laid off for a period of six weeks, the employee shall be deemed to be “separated from service” during such period for purposes of the entry date requirements.

(B) Application. A period of severance which is taken into account under the service spanning rules in paragraph (c)(2)(iii) of this section or an absence of 12 months or less may result in an employee satisfying the plan's minimum service requirement during such period of time. In addition, once an employee satisfies the plan's minimum service requirement, either before or during such period of time, such period of time may contain an entry date applicable to such employee. In the case of an employee whose period of severance is taken into account and such period contains an entry date applicable to the employee, he or she shall be made a participant in the plan (if otherwise eligible) no later than the date on which he or she ended the period of severance. In the case of an employee whose period of absence contains an entry date applicable to such employee, he or she, no later than the date such absence ended, shall be made a participant in the plan (if otherwise eligible) as of the first applicable entry date which occurred during such absence from service.

(iii) Examples. For purposes of the following examples, assume that the plan provides for a minimum age requirement of 25 and a minimum service requirement of one year, and provides for semi-annual entry dates.

(A) Employee A, age 35, worked for 10 months in a job classification covered under the plan, became disabled for nine consecutive months and then returned to service. During the period of absence, A completed a 1-year period of service and passed a semi-annual entry date after satisfying the minimum service requirement. Accordingly, the plan is required to make A a participant no later than his return to service effective as of the applicable entry date.

(B) Employee B, after satisfying the minimum age and service requirements, quit work before the next semi-annual entry date, and then returned to service before incurring a 1-year period of severance, but after such semi-annual entry date. Employee B is entitled to become a participant immediately upon his return to service effective as of the date of his return.

(4) Break in service. For purposes of applying the break in service rules under section 410(a)(5) (B) and (C), the term “1-year period of severance” shall be substituted for the term “1-year break in service”. A 1-year period of severance shall be determined on the basis of a 12-consecutive-month period beginning on the severance from service date and ending on the first anniversary of such date, provided that the employee during such 12-consecutive-month period does not perform an hour of service within the meaning of 29 CFR 2530.200b-2(a)(1) for the employer or employers maintaining the plan.

(5) One-year hold-out—(i) General rule. (A) For purposes of section 410(a)(5)(C), in determining the period of service of an employee who has incurred a 1-year period of severance, a plan may disregard the employee's period of service before such period of severance until the employee completes a 1-year period of service after such period of severance.

(B) Example. Assume that a plan provides for a minimum service requirement of 1-year and provides for semi-annual entry dates, but does not contain the provisions permitted by section 410(a)(5)(D) (relating to the rule of parity). Employee G, age 40, completed a seven-month period of service, quit and then returned to service 15 months later, thereby incurring a 1-year period of severance. After working four months, G was laid off for nine months and then returned to work again. Although the plan may hold employee G out from participation in the plan until the completion of a 1-year period of service after the 1-year (or greater) period of severance, once the 1-year hold-out is completed, the plan is required to provide the employee with such statutory entitlement as arose during the 1-year hold-out. Accordingly, employee G satisfied the 1-year hold-out requirement as of the eighth month of layoff, and G is entitled to become a participant in the plan immediately upon his return to service after the nine-month layoff effective as of the first applicable entry date occurring after the date on which he satisfied the 1-year of service requirement (i.e., the first applicable entry date after the first month of layoff). See the regulations under section 410 (a) (relating to eligibility to participate).

(6) Rule of parity—(i) General rule. For purposes of section 410(a)(5)(D), in the case of a participant who does not have any nonforfeitable right under the plan to his accrued benefit derived from employer contributions and who incurs a 1-year period of severance, a plan, in determining an employee's period of service for purposes of section 410(a)(1), may disregard his period of service if his latest period of severance equals or exceeds his prior periods of service, whether or not consecutive, completed before such period of severance. See the regulations under section 410(a) (relating to eligibility to participate).

(ii) In determining whether a completely nonvested employee's service may be disregarded under the rule of parity, a plan is not permitted to apply the rule until the employee incurs a 1-year period of severance. Accordingly, a plan may not disregard a period of service of less than one year until an employee has incurred a period of severance of at least one year.

(iii) Example. Assume that a plan provides for a minimum service requirement of one year and provides for the rule of parity. An employee works for three months, quits and then is rehired 10 months later. Such employee is entitled to receive 13 months of credit for purposes of eligibility to participate and vesting (see the service spanning rules). Although the period of severance exceeded the period of service, the three months of service may not be disregarded because no 1-year period of severance occurred.

(d) Vesting—(1) General rule. (i) For purposes of section 411(a)(2), relating to vesting in accrued benefits derived from employer contributions, a plan which determines service to be taken in account on the basis of elapsed time shall provide that an employee is credited with a number of years of service equal to at least the number of whole years of the employee's period of service, whether or not such periods of service were completed consecutively.

(ii) In order to determine the number of whole years of an employee's period of service, a plan shall provide that non-successive periods of service must be aggregated and that less than whole year periods of service (whether or not consecutive) must be aggregated on the basis that 12 months of service (30 days are deemed to be a month in the case of the aggregation of fractional months) or 365 days of service equal a whole year of service.

(iii) Service spanning rules. In determining a participant's period of service for vesting purposes, a plan shall take into account the following periods of severance—

(A) If an employee severs from service by reason of a quit, discharge or retirement and the employee then performs an hour of service within the meaning of 29 CFR 2530.200b-2(a)(1) within 12 months of the severance from service date, the plan is required to take into account the period of severance; and

(B) Nothwithstanding paragraph (d)(1)(iii)(A) of this section, if an employee severs from service by reason of a quit, discharge or retirement during an absence from service of 12 months or less for any reason other than a quit, discharge, retirement or death, and then performs an hour of service within the meaning of 29 CFR 2530.200b-2(a)(1) within 12 months of the date on which the employee was first absent from service, the plan is required to take into account the period of severance.

(iv) For purposes of determining an employee's nonforfeitable percentage of accrued benefits derived from employer contributions, a plan, after calculating an employee's period of service in the manner prescribed in this paragraph, may disregard any remaining less than whole year, 12-month or 365-day period of service. Thus, for example, if a plan provides for the statutory five to fifteen year graded vesting, an employee with a period (or periods) of service which yield 5 whole year periods of service and an additional 321-day period of service is twenty-five percent vested in his or her employer-derived accrued benefits (based solely on the 5 whole year periods of service).

(2) Service which may be disregarded. (i) For purposes of section 411(a)(4), in determining the nonforfeitable percentage of an employee's right to his or her accrued benefits derived from employer contributions, all of an employee's period or periods of service with an employer or employers maintaining the plan shall be taken into account unless such service may be disregarded under paragraph (d)(2)(ii) of this section.

(ii) For purposes of paragraph (d)(2)(i) of this section, the following periods of service may be disregarded—

(A) The period of service completed by an employee before the date on which he attains age 22;

(B) In the case of a plan which requires mandatory employee contributions, the period of service which falls within the period of time to which a particular employee contribution relates, if the employee had the opportunity to make a contribution for such period of time and failed to do so;

(C) The period of service during any period for which the employer did not maintain the plan or a predecessor plan;

(D) The period of service which is not required to be taken into account by reason of a period of severance which constitutes a break in service within the meaning of paragraph (d)(4) of this section;

(E) The period of service completed by an employee prior to January 1, 1971, unless the employee completes a period of service of at least 3 years at any time after December 31, 1970; and

(F) The period of service completed before the first plan year for which this section applies to the plan, if such service would have been disregarded under the plan rules relating to breaks in service in effect at that time. See the regulations under section 411(a) (relating to vesting).

(3) Seasonal industry. [Reserved]

(4) Break in service. For purposes of applying the break in service rules, the term “1-year period of severance” shall be substituted for the term “1-year break in service”. A 1-year period of severance shall be a 12-consecutive-month period beginning on the severance from service date and ending on the first anniversary of such date, provided that the employee during such 12-consecutive-month period fails to perform an hour of service within the meaning of 29 CFR 2530.200b-2(a)(1) for an employer or employers maintaining the plan.

(5) One-year hold-out. For purposes of section 411(a)(6)(B), in determining the nonforfeitable percentage of the right to accrued benefits derived from employer contributions of an employee who has incurred a 1-year period of severance, the period of service completed before such period of severance is not required to be taken into account until the employee has completed a 1-year period of service after his return to service. See the regulations under section 411(a) (relating to vesting).

(6) Vesting in pre-break accruals. For purposes of section 411(a)(6)(C), a “1-year period of severance” shall be deemed to constitute a “1-year break in service.” See the regulations under section 411(a) (relating to vesting).

(7) Rule of partity—(i) General rule. For purposes of section 411(a)(6)(D), in the case of an employee who is a nonvested participant in employer-derived benefits at the time he incurs a 1-year period of severance, the period of service completed by such participant before such period of severance is not required to be taken into account for purposes of determining the vested percentage of his or her right to employer-derived benefits if at such time the consecutive period of severance equals or exceeds his prior periods of service, whether or not consecutive, completed before such period of severance. See the regulations under section 411(a) (relating to vesting).

(e) Benefit accrual. (1) For purposes of section 411(b), a plan may provide that a participant's service with an employer or employers maintaining the plan shall be determined on the basis of the participant's total period of service beginning on the participation commencement date and ending on the severance from service date.

(2) Under section 411(b)(3)(A), a defined benefit pension plan may determine an employee's service for purposes of benefit accrual on any basis which is reasonable and consistent and which takes into account all service during the employee's participation in the plan which is included in a period of service required to be taken into account under section 410(a)(5) (relating to service which must be taken into account for purposes of determining an employee's eligibility to participate). A plan which provides for the determination of an employee's service with an employer or employers maintaining the plan on the basis permitted under paragraph (e)(1) of this section will be deemed to meet the requirements of section 411(b)(3)(A), provided that the plan meets the requirements of 29 CFR 2530.204-3, relating to plans which determine an employee's service for purposes of benefit accrual on a basis other than computation periods. Specifically, under 29 CFR 2530.204-3, it must be possible to prove that, despite the fact that benefit accrual under such a plan is not based on computation periods, the plan's provisions meet at least one of the three benefit accrual rules of section 411(b)(1) under all circumstances. Further, 29 CFR 2530.204-3 prohibits such a plan from disregarding service under section 411(b)(3)(C) (which would otherwise permit a plan to disregard service performed by an employee during a computation period in which the employee is credited with less than 1,000 hours). See the regulations under section 411(b) (relating to benefit accrual).

(f) Transfers between methods of crediting service—(1) Single plan. A plan may provide that an employee's service for purposes of eligibility to participate, vesting or benefit accrual shall be determined on the basis of computation periods under the general method set forth in 29 CFR 2530.200b-2 for certain classes of employees but under the alternative method permitted under this section for other classes of employees if the plan provides as follows—

(i) In the case of an employee who transfers from a class of employees whose service is determined on the basis of computation periods to a class of employees whose service is determined on the alternative basis permitted under this section, the employee shall receive credit for a period of service consisting of—

(A) A number of years equal to the number of years of service credited to the employee before the computation period during which the transfer occurs; and

(B) The greater of (1) the period of service that would be credited to the employee under the elapsed time method for his service during the entire computation period in which the transfer occurs or (2) the service taken into account under the computation periods method as of the date of the transfer.

In addition, the employee shall receive credit for service subsequent to the transfer commencing on the day after the last day of the computation period in which the transfer occurs.

(ii) In the case of an employee who transfers from a class of employees whose service is determined on the alternative basis permitted under this section to a class of employees whose service is determined on the basis of computation periods—

(A) The employee shall receive credit, as of the date of the transfer, for a number of years of service equal to the number of 1-year periods of service credited to the employee as of the date of the transfer, and

(B) The employee shall receive credit, in the computation period which includes the date of the transfer, for a number of hours of service determined by applying one of the equivalencies set forth in 29 CFR 2530.200b-3 (e) (1) to any fractional part of a year credited to the employee under this section as of the date of the transfer. Such equivalency shall be set forth in the plan and shall apply to all similarly situated employees.

(2) More than one plan. In the case of an employee who transfers from a plan using either the general method of determining service on the basis of computation periods set forth in 29 CFR 2530.200b-2 or the method of determining service permitted under this section to a plan using the other method of determining service, all service required to be credited under the plan to which the employee transfers shall be determined by applying the rules of paragraph (f)(1) of this section.

(g) Amendments to change method of crediting service. A plan may be amended to change the method of crediting service for any purpose or for any class of employees between the general method set forth in 29 CFR 2530.200-2 and the method permitted under this section, if such amendment contains provisions under which each employee with respect to whom the method of crediting service is changed is treated in the same manner as an employee who transfers from one class of employees to another under paragraph (f)(1) of this section.

(h) Transitional rule. For plans in existence on [insert the date of the publication of this document], the provisions of paragraph (f) of this section are effective for plan years beginning after December 31, 1983.

Sections 410(a)(5)(D) and 411(a)(6)(D), as amended by the Retirement Equity Act of 1984 (REA 1984), permit a plan to disregard years of service that were disregarded under the plan provisions satisfying those sections (as in effect on August 22, 1984) as of the day before the REA amendments apply to the plan. Under section 302(a) of REA 1984, the new break-in-service rules generally apply to plan years beginning after December 31, 1984. Thus, for example, assume a plan has a calendar plan year and disregarded years of service as permitted by sections 410(a)(5)(D) and 411(a)(6)(D) as in effect on August 22, 1984. An employee completed two years of service in 1981 and 1982, and then incurred two consecutive 1-year breaks in service in 1983 and 1984. The plans may disregard the prior years of service even though the employee did not incur five consecutive 1-year breaks in service. On the other hand, assume the employee completed three consecutive years of service beginning in 1980, and incurred two 1-year breaks in service in 1983 and 1984. Because, as of December 31, 1984, the years of service credited before 1983 could not be disregarded, whether the plan may subsequently disregard those years of service would be governed by the rules enacted by REA 1984.

(a)-(b) [Reserved]

(c) Breaks in service. (1) [Reserved]

(2) Employees under 2-year 100 percent vesting schedule—(i) General rule. In the case of an employee who incurs a 1-year break in service under a plan which provides that after not more than 2 years of service each participant's right to his accrued benefit under the plan is completely nonforfeitable (within the meaning of section 411 and the regulations thereunder) at the time such benefit accrues, the employee's service before the break in service is not required to be taken into account after the break in service in determining the employee's years of service under section 410(a)(1) and § 1.410(a)-3 if such employee has not satisfied such service requirement.

(ii) Example. The rules of this subparagraph are illustrated by the following example:

(3) One-year break in service—

(i) [Reserved]

(ii) Examples. The rules provided by this subparagraph are illustrated by the following examples:

Q-1: What account limits apply to welfare benefit funds that are maintained pursuant to a collective bargaining agreement?

A-1: Contributions to a welfare benefit fund maintained pursuant to one or more collective bargaining agreements and the reserves of such a fund generally are subject to the rules of sections 419, 419A, and 512. However, neither contributions to nor reserves of such a collectively bargained welfare benefit fund shall be treated as exceeding the otherwise applicable limits of section 419(b), 419A(b), or 512(a)(3)(E) until the earlier of: (i) The date on which the last of the collective bargaining agreements relating to the fund in effect on, or ratified on or before, the date of issuance of final regulations concerning such limits for collectively bargained welfare benefit funds terminates (determined without regard to any extension thereof agreed to after the date of issuance of such final regulations), or (ii) the date 3 years after the issuance of such final regulations.

Q-2: What is a welfare benefit fund maintained pursuant to a collective bargaining agreement for purposes of Q&A-1?

A-2: (1) For purposes of Q&A-1, a collectively bargained welfare benefit fund is a welfare benefit fund that is maintained pursuant to an agreement which the Secretary of Labor determines to be a collective bargaining agreement and which meets the requirements of the Secretary of the Treasury as set forth in paragraph 2 below.

(2) Notwithstanding a determination by the Secretary of Labor that an agreement is a collective bargaining agreement, a welfare benefit fund is considered to be maintained pursuant to a collective bargaining agreement only if the benefits provided through the fund were the subject of arms-length negotiations between employee representatives and one or more employers, and if such agreement between employee representatives and one or more employers satisfies section 7701(a)(46) of the Code. Moreover, the circumstances surrounding a collective bargaining agreement must evidence good faith bargaining between adverse parties over the welfare benefits to be provided through the fund. Finally, a welfare benefit fund is not considered to be maintained pursuant to a collective bargaining agreement unless at least 50 percent of the employees eligible to receive benefits under the fund are covered by the collective bargaining agreement.

(3) In the case of a collectively bargained welfare benefit fund, only the portion of the fund (as determined under allocation rules to be provided by the Commissioner) attributable to employees covered by a collective bargaining agreement, and from which benefits for such employees are provided, is considered to be maintained pursuant to a collective bargaining agreement.

(4) Notwithstanding the preceding paragraphs and pending the issuance of regulations setting account limits for collectively bargained welfare benefit funds, a welfare benefit fund will not be treated as a collectively bargained welfare benefit fund for purposes of Q&A-1 if and when, after July 1, 1985, the number of employees who are not covered by a collective bargaining agreement and are eligible to receive benefits under the fund increases by reason of an amendment, merger, or other action of the employer or the fund. In addition, pending the issuance of such regulations, for purposes of applying the 50 percent test of paragraph (2) to a welfare benefit fund that is not in existence on July 1, 1985, “90 percent” shall be substituted for “50 percent”.

(a) Requirements—(1) In general. Sections 419 and 419A do not apply in the case of a welfare benefit fund that is part of a 10 or more employer plan described in section 419A(f)(6). A plan is a 10 or more employer plan described in section 419A(f)(6) only if it is a single plan—

(i) To which more than one employer contributes;

(ii) To which no employer normally contributes more than 10 percent of the total contributions contributed under the plan by all employers;

(iii) That does not maintain an experience-rating arrangement with respect to any individual employer; and

(iv) That satisfies the requirements of paragraph (a)(2) of this section.

(2) Compliance information. A plan satisfies the requirements of this paragraph (a)(2) if the plan is maintained pursuant to a written document that requires the plan administrator to maintain records sufficient for the Commissioner or any participating employer to readily verify that the plan satisfies the requirements of section 419A(f)(6) and this section and that provides the Commissioner and each participating employer (or a person acting on the participating employer's behalf) with the right, upon written request to the plan administrator, to inspect and copy all such records. See § 1.414(g)-1 for the definition of plan administrator.

(3) Application of rules—(i) In general. The requirements described in paragraph (a)(1) and (2) of this section must be satisfied both in form and in operation.

(ii) Arrangement is considered in its entirety. The determination of whether a plan is a 10 or more employer plan described in section 419A(f)(6) is based on the totality of the arrangement and all related facts and circumstances, including any related insurance contracts. Accordingly, all agreements and understandings (including promotional materials and policy illustrations) and the terms of any insurance contract will be taken into account in determining whether the requirements are satisfied in form and in operation.

(b) Experience-rating arrangements—(1) General rule. A plan maintains an experience-rating arrangement with respect to an individual employer and thus does not satisfy the requirement of paragraph (a)(1)(iii) of this section if, with respect to that employer, there is any period for which the relationship of contributions under the plan to the benefits or other amounts payable under the plan (the cost of coverage) is or can be expected to be based, in whole or in part, on the benefits experience or overall experience (or a proxy for either type of experience) of that employer or one or more employees of that employer. For purposes of this paragraph (b)(1), an employer's contributions include all contributions made by or on behalf of the employer or the employer's employees. See paragraph (d) of this section for the definitions of benefits experience, overall experience, and benefits or other amounts payable. The rules of this paragraph (b) apply under all circumstances, including employer withdrawals and plan terminations.

(2) Adjustment of contributions. An example of a plan that maintains an experience-rating arrangement with respect to an individual employer is a plan that entitles an employer to (or for which the employer can expect) a reduction in future contributions if that employer's overall experience is positive. Similarly, a plan maintains an experience-rating arrangement with respect to an individual employer where an employer can expect its future contributions to be increased if the employer's overall experience is negative. A plan also maintains an experience-rating arrangement with respect to an individual employer where an employer is entitled to receive (or can expect to receive) a rebate of all or a portion of its contributions if that employer's overall experience is positive or, conversely, where an employer is liable to make additional contributions if its overall experience is negative.

(3) Adjustment of benefits. An example of a plan that maintains an experience-rating arrangement with respect to an individual employer is a plan under which benefits for an employer's employees are (or can be expected to be) increased if that employer's overall experience is positive or, conversely, under which benefits are (or can be expected to be) decreased if that employer's overall experience is negative. A plan also maintains an experience-rating arrangement with respect to an individual employer if benefits for an employer's employees are limited by reference, directly or indirectly, to the overall experience of the employer (rather than having all the plan assets available to provide the benefits).

(4) Special rules—(i) Treatment of insurance contracts—(A) In general. For purposes of this section, insurance contracts under the arrangement will be treated as assets of the fund. Accordingly, the value of the insurance contracts (including non-guaranteed elements) is included in the value of the fund, and amounts paid between the fund and the insurance company are disregarded, except to the extent they generate gains or losses as described in paragraph (b)(4)(i)(C) of this section.

(B) Payments to and from an insurance company. Payments from a participating employer or its employees to an insurance company pursuant to insurance contracts under the arrangement will be treated as contributions made to the fund, and amounts paid under the arrangement from an insurance company will be treated as payments from the fund.

(C) Gains and losses from insurance contracts. As of any date, if the sum of the benefits paid by the insurer and the value of the insurance contract (including non-guaranteed elements) is greater than the cumulative premiums paid to the insurer, the excess is treated as a gain to the fund. As of any date, if the cumulative premiums paid to the insurer are greater than the sum of the benefits paid by the insurer and the value of the insurance contract (including non-guaranteed elements), the excess is treated as a loss to the fund.

(ii) Treatment of flexible contribution arrangements. Solely for purposes of determining the cost of coverage under a plan, if contributions for any period can vary with respect to a benefit package, the Commissioner may treat the employer as contributing the minimum amount that would maintain the coverage for that period.

(iii) Experience rating by group of employers or group of employees. A plan will not be treated as maintaining an experience-rating arrangement with respect to an individual employer merely because the cost of coverage under the plan with respect to the employer is based, in whole or in part, on the benefits experience or the overall experience (or a proxy for either type of experience) of a rating group, provided that no employer normally contributes more than 10 percent of all contributions with respect to that rating group. For this purpose, a rating group means a group of participating employers that includes the employer or a group of employees covered under the plan that includes one or more employees of the employer.

(iv) Family members, etc. For purposes of this section, contributions with respect to an employee include contributions with respect to any other person (e.g., a family member) who may be covered by reason of the employee's coverage under the plan and amounts provided with respect to an employee include amounts provided with respect to such a person.

(v) Leased employees. In the case of an employer that is the recipient of services performed by a leased employee described in section 414(n)(2) who participates in the plan, the leased employee is treated as an employee of the recipient and contributions made by the leasing organization attributable to service performed with the recipient are treated as made by the recipient.

(c) Characteristics indicating a plan is not a 10 or more employer plan—(1) In general. The presence of any of the characteristics described in paragraphs (c)(2) through (c)(6) of this section generally indicates that the plan is not a 10 or more employer plan described in section 419A(f)(6). Accordingly, unless established to the satisfaction of the Commissioner that the plan satisfies the requirements of section 419A(f)(6) and this section, a plan having any of the following characteristics is not a 10 or more employer plan described in section 419A(f)(6). A plan's lack of all the following characteristics does not create any inference that the plan is a 10 or more employer plan described in section 419A(f)(6).

(2) Allocation of plan assets. Assets of the plan or fund are allocated to a specific employer or employers through separate accounting of contributions and expenditures for individual employers, or otherwise.

(3) Differential pricing. The amount charged under the plan is not the same for all the participating employers, and those differences are not merely reflective of differences in current risk or rating factors that are commonly taken into account in manual rates used by insurers (such as current age, gender, geographic locale, number of covered dependents, and benefit terms) for the particular benefit or benefits being provided.

(4) No fixed welfare benefit package. The plan does not provide for fixed welfare benefits for a fixed coverage period for a fixed cost, within the meaning of paragraph (d)(5) of this section.

(5) Unreasonably high cost. The plan provides for fixed welfare benefits for a fixed coverage period for a fixed cost, but that cost is unreasonably high for the covered risk for the plan as a whole.

(6) Nonstandard benefit triggers. Benefits or other amounts payable can be paid, distributed, transferred, or otherwise provided from a fund that is part of the plan by reason of any event other than the illness, personal injury, or death of an employee or family member, or the employee's involuntary separation from employment. Thus, for example, a plan exhibits this characteristic if the plan provides for the payment of benefits or the distribution of an insurance contract to an employer's employees on the occasion of the employer's withdrawal from the plan. A plan will not be treated as having the characteristic described in this paragraph merely because, upon cessation of participation in the plan, an employee is provided with the right to convert coverage under a group life insurance contract to coverage under an individual life insurance contract without demonstrating evidence of insurability, but only if there is no additional economic value associated with the conversion right.

(d) Definitions. For purposes of this section:

(1) Benefits or other amounts payable. The term benefits or other amounts payable includes all amounts that are payable or distributable (or that will be otherwise provided) directly or indirectly to employers, to employees or their beneficiaries, or to another fund as a result of a spinoff or transfer, and without regard to whether payable or distributable as welfare benefits, cash, dividends, rebates of contributions, property, promises to pay, or otherwise.

(2) Benefits experience. The benefits experience of an employer (or of an employee or a group of employers or employees) means the benefits and other amounts incurred, paid, or distributed (or otherwise provided) directly or indirectly, including to another fund as a result of a spinoff or transfer, with respect to the employer (or employee or group of employers or employees), and without regard to whether provided as welfare benefits, cash, dividends, credits, rebates of contributions, property, promises to pay, or otherwise.

(3) Overall experience—(i) Employer's overall experience. The term overall experience means, with respect to an employer (or group of employers), the balance that would have accumulated in a welfare benefit fund if that employer (or those employers) were the only employer (or employers) providing welfare benefits under the plan. Thus, the overall experience is credited with the sum of the contributions under the plan with respect to that employer (or group of employers), less the benefits and other amounts paid or distributed (or otherwise provided) with respect to that employer (or group of employers) or the employees of that employer (or group of employers), and adjusted for gain or loss from insurance contracts (as described in paragraph (b)(4)(i) of this section), investment return, and expenses. Overall experience as of any date may be either a positive or a negative number.

(ii) Employee's overall experience. The term overall experience means, with respect to an employee (or group of employees, whether or not employed by the same employer), the balance that would have accumulated in a welfare benefit fund if the employee (or group of employees) were the only employee (or employees) being provided welfare benefits under the plan. Thus, the overall experience is credited with the sum of the contributions under the plan with respect to that employee (or group of employees), less the benefits and other amounts paid or distributed (or otherwise provided) with respect to that employee (or group of employees), and adjusted for gain or loss from insurance contracts (as described in paragraph (b)(4)(i) of this section), investment return, and expenses. Overall experience as of any date may be either a positive or a negative number.

(4) Employer. The term employer means the employer whose employees are participating in the plan and those employers required to be aggregated with the employer under section 414(b), (c), or (m).

(5) Fixed welfare benefit package—(i) In general. A plan provides for fixed welfare benefits for a fixed coverage period for a fixed cost, if it—

(A) Defines one or more welfare benefits, each of which has a fixed amount that does not depend on the amount or type of assets held by the fund;

(B) Specifies fixed contributions to provide for those welfare benefits; and

(C) Specifies a coverage period during which the plan agrees to provide specified welfare benefits, subject to the payment of the specified contributions by the employer.

(ii) Treatment of actuarial gains or losses. A plan will not be treated as failing to provide for fixed welfare benefits for a fixed coverage period for a fixed cost merely because the plan does not pay the promised benefits (or requires all participating employers to make proportionate additional contributions based on the fund's shortfall) when there are insufficient assets under the plan to pay the promised benefits. Similarly, a plan will not be treated as failing to provide for fixed welfare benefits for a fixed coverage period for a fixed cost merely because the plan provides a period of extended coverage after the end of the coverage period with respect to employees of all participating employers at no cost to the employers (or provides a proportionate refund of contributions to all participating employers) because of the plan-wide favorable actuarial experience during the coverage period.

(e) Maintenance of records. The plan administrator of a plan that is intended to be a 10 or more employer plan described in section 419A(f)(6) shall maintain permanent records and other documentary evidence sufficient to substantiate that the plan satisfies the requirements of section 419A(f)(6) and this section. (See § 1.414(g)-1 for the definition of plan administrator.)

(f) Examples. The provisions of paragraph (c) of this section and the provisions of section 419A(f)(6) and this section relating to experience-rating arrangements may be illustrated by the following examples. Unless stated otherwise, it should be assumed that any life insurance contract described in an example is non-participating and has no value other than the value of the policy's current life insurance protection plus its cash value, and that no employer normally contributes more than 10 percent of the total contributions contributed under the plan by all employers. Paragraph (ii) of each example applies the characteristics listed in paragraph (c) of this section to the facts described in that example. Paragraphs (iii) and (iv) of each example analyze the facts described in the example to determine whether the plan maintains experience-rating arrangements with respect to individual employers. Paragraphs (iii) and (iv) of each example illustrate only the meaning of experience-rating arrangements. No inference should be drawn from these examples about whether these plans are otherwise described in section 419A(f)(6) or about the applicability or nonapplicability of any other Internal Revenue Code provision that may limit or deny the deduction of contributions to the arrangements. Further, no inference should be drawn from the examples concerning the tax treatment of employees as a result of the employer contributions or the provision of the benefits. The examples are as follows:

(g) Effective date—(1) In general. Except as set forth in paragraph (g)(2) of this section, this section applies to contributions paid or incurred in taxable years of an employer beginning on or after July 11, 2002.

(2) Compliance information and recordkeeping. Paragraphs (a)(1)(iv), (a)(2), and (e) of this section apply for taxable years of a welfare benefit fund beginning after July 17, 2003.

(a) In general. Notwithstanding section 420(c)(3)(A), the minimum cost requirements of section 420(c)(3) are not met if the employer significantly reduces retiree health coverage during the cost maintenance period.

(b) Significant reduction—(1) In general. An employer significantly reduces retiree health coverage during the cost maintenance period if, for any taxable year beginning on or after January 1, 2002, that is included in the cost maintenance period, either—

(i) The employer-initiated reduction percentage for that taxable year exceeds 10 percent; or

(ii) The sum of the employer-initiated reduction percentages for that taxable year and all prior taxable years during the cost maintenance period exceeds 20 percent.

(2) Employer-initiated reduction percentage. The employer-initiated reduction percentage for any taxable year is the fraction B/A, expressed as a percentage, where:

(3) Special rules for taxable years beginning before January 1, 2002. The following rules apply for purposes of computing the amount in paragraph (b)(1)(ii) of this section if any portion of the cost maintenance period precedes the first day of the first taxable year beginning on or after January 1, 2002—

(i) Aggregation of taxable years. The portion of the cost maintenance period that precedes the first day of the first taxable year beginning on or after January 1, 2002 (the initial period) is treated as a single taxable year and the employer-initiated reduction percentage for the initial period is computed as set forth in paragraph (b)(2) of this section, except that the words “initial period” apply instead of “taxable year.”

(ii) Loss of coverage. If coverage for applicable health benefits for an individual ends by reason of employer action at any time during the initial period, an employer may treat that coverage as not having ended if the employer restores coverage for applicable health benefits to that individual by the end of the initial period.

(4) Employer action—(i) General rule. For purposes of paragraph (b)(2) of this section, an individual's coverage for applicable health benefits ends during a taxable year by reason of employer action, if on any day within the taxable year, the individual's eligibility for applicable health benefits ends as a result of a plan amendment or any other action of the employer (e.g., the sale of all or part of the employer's business) that, in conjunction with the plan terms, has the effect of ending the individual's eligibility. An employer action is taken into account for this purpose regardless of when the employer action actually occurs (e.g., the date the plan amendment is executed), except that employer actions occurring before the later of December 18, 1999, and the date that is 5 years before the start of the cost maintenance period are disregarded.

(ii) Special rule. Notwithstanding paragraph (b)(4)(i) of this section, coverage for an individual will not be treated as having ended by reason of employer action merely because such coverage ends under the terms of the plan if those terms were adopted contemporaneously with the provision under which the individual became eligible for retiree health coverage. This paragraph (b)(4)(ii) does not apply with respect to plan terms adopted contemporaneously with a plan amendment that restores coverage for applicable health benefits before the end of the initial period in accordance with paragraph (b)(3)(ii) of this section.

(iii) Sale transactions. If a purchaser provides coverage for retiree health benefits to one or more individuals whose coverage ends by reason of a sale of all or part of the employer's business, the employer may treat the coverage of those individuals as not having ended by reason of employer action. In such a case, for the remainder of the year of the sale and future taxable years of the cost maintenance period—

(A) For purposes of computing the applicable employer cost under section 420(c)(3), those individuals are treated as individuals to whom coverage for applicable health benefits was provided (for as long as the purchaser provides retiree health coverage to them), and any amounts expended by the purchaser of the business to provide for health benefits for those individuals are treated as paid by the employer;

(B) For purposes of determining whether a subsequent termination of coverage is by reason of employer action under this paragraph (b)(4), the purchaser is treated as the employer. However, the special rule in paragraph (b)(4)(ii) of this section applies only to the extent that any terms of the plan maintained by the purchaser that have the effect of ending retiree health coverage for an individual are the same as terms of the plan maintained by the employer that were adopted contemporaneously with the provision under which the individual became eligible for retiree health coverage under the plan maintained by the employer.

(c) Definitions. The following definitions apply for purposes of this section:

(1) Applicable health benefits. Applicable health benefits means applicable health benefits as defined in section 420(e)(1)(C).

(2) Cost maintenance period. Cost maintenance period means the cost maintenance period as defined in section 420(c)(3)(D).

(3) Sale. A sale of all or part of an employer's business means a sale or other transfer in connection with which the employees of a trade or business of the employer become employees of another person. In the case of such a transfer, the term purchaser means a transferee of the trade or business.

(d) Examples. The following examples illustrate the application of this section:

(e) Regulatory effective date. This section is applicable to transfers of excess pension assets occurring on or after December 18, 1999.

(a) Elapsed time—(1) Rule. For purposes of applying the rules of § 1.410(a)-7 (relating to the elapsed time method of crediting service) to absences described in sections 410(a)(5)(E) and 411(a)(6)(E) (relating to maternity or paternity absence), the severance from service date of an employee who is absent from service beyond the first anniversary of the first day of absence by reason of a maternity or paternity absence described in section 410(a)(5)(E)(i) or 411(a)(6)(E)(i) is the second anniversary of the first day of such absence. The period between the first and second anniversaries of the first day of absence from work is neither a period of service nor a period of severance. This rule applies to maternity and paternity absences beginning on or after the first day of the first plan year in which the plan is required to credit service under sections 410(a)(5)(E) and 411(a)(6)(E).

(2) Example. The rules of this section are illustrated by the following example:

(b) Other methods. This paragraph provides a safe harbor for plans that compute years of service under the hours of service methods or permitted equivalencies. Such a plan will be treated as satisfying the requirements of sections 410(a)(5)(E) and 411(a)(6)(E) if the plan increases the minimum period of consecutive 1-year breaks required to disregard any service (or deprive any employee of any right) by one. Thus, a plan will satisfy sections 410(a)(5)(E) and 411(a)(6)(E) without having to compute service for maternity or paternity and sections 410(a)(5)(D) and 411 (a)(4)(D) and (a)(6)(C), by increasing the period of consecutive breaks-in-service from 5 to 6.

(a)-(b) [Reserved]

(c) Eligibility to participate. (1) [Reserved]

(2) Determination of one-year period of service.

(i) [Reserved]

(ii) For purposes of section 410(a)(1)(B)(i), a “2-year period of service” shall be deemed to be “2 years of service.”

(d) Vesting—(1) General rule.

(i)-(iii) [Reserved]

(iv) For purposes of determining an employee's nonforfeitable percentage of accrued benefits derived from employer contributions, a plan, after calculating an employee's period of service in the manner prescribed in this paragraph, may disregard any remaining less than whole year, 12-month or 365-day period of service. Thus, for example, if a plan provides for the statutory three to seven year graded vesting, an employee with a period (or periods) of service which yields 3 whole year periods of service and an additional 321-day period of service is twenty percent vested in his or her employer-derived accrued benefits (based solely on the 3 whole year periods of service).

This section contains a listing of the major headings of §§ 1.410(b)-2 through 1.410(b)-10.

(a) In general. A plan is a qualified plan for a plan year only if the plan satisfies section 410(b) for the plan year. A plan satisfies section 410(b) for a plan year if and only if it satisfies paragraph (b) of this section with respect to employees for the plan year and paragraph (c) of this section with respect to former employees for the plan year. The rules in paragraphs (a), (b), and (c) of this section apply to all plans as a condition of qualification, including plans under which no employee is able to accrue any additional benefits (for example, frozen plans). Paragraphs (d), (e), and (f) of this section provide special rules for nonelective section 403(b) plans subject to section 403(b)(12)(A)(i), for governmental and church plans subject to section 410(c), and for certain acquisitions or dispositions, respectively. See § 1.410(b)-7 for rules for determining the “plan” subject to section 410(b).

(b) Requirements with respect to employees—(1) In general. A plan satisfies this paragraph (b) for a plan year if and only if it satisfies at least one of the tests in paragraphs (b)(2) through (b)(7) of this section for the plan year.

(2) Ratio percentage test—(i) In general. A plan satisfies this paragraph (b)(2) for a plan year if and only if the plan's ratio percentage for the plan year is at least 70 percent. This test incorporates both the percentage test of section 410(b)(1)(A) and the ratio test of section 410(b)(1)(B). See § 1.410(b)-9 for the definition of ratio percentage.

(ii) Examples. The following examples illustrate the ratio percentage test of this paragraph (b)(2).

(3) Average benefit test. A plan satisfies this paragraph (b)(3) for a plan year if and only if the plan satisfies both the nondiscriminatory classification test of § 1.410(b)-4 and the average benefit percentage test of § 1.410(b)-5 for the plan year.

(4) Certain tax credit employee stock ownership plans. A plan satisfies this paragraph (b)(4) for a plan year if and only if the plan—

(i) Is a tax credit employee stock ownership plan (as defined in section 409(a)),

(ii) Is the only plan of the employer that is intended to qualify under section 401(a), and

(iii) Is a plan that satisfies the rule set forth in section 410(b)(6)(D).

This paragraph (b)(4) is available only for plan years for which the tax credit employee stock ownership plan receives contributions for which the employer is allowed a tax credit under section 41 (as in effect prior to its repeal by the Tax Reform Act of 1986) or section 48(n) (as in effect prior to its amendment by the Tax Reform Act of 1984). The requirement of this paragraph (b)(4) that the plan be the only plan of the employer that is intended to qualify under section 401(a) is not satisfied if the employer has only one plan, but that plan is treated as two or more separate plans under the mandatory disaggregation rules of § 1.410(b)-7(c).

(5) Employers with no nonhighly compensated employees. A plan satisfies this paragraph (b)(5) for a plan year if and only if the plan is maintained by an employer that has no nonhighly compensated employees at any time during the plan year.

(6) Plans benefiting no highly compensated employees. A plan satisfies this paragraph (b)(6) for a plan year if and only if the plan benefits no highly compensated employees for the plan year.

(7) Plans benefiting collectively bargained employees. A plan that benefits solely collectively bargained employees for a plan year satisfies this paragraph (b)(7) for the plan year. If a plan (within the meaning of § 1.410(b)-7(b)) benefits both collectively bargained employees and noncollectively bargained employees for a plan year, § 1.410(b)-7(c)(4) provides that the portion of the plan that benefits collectively bargained employees is treated as a separate plan from the portion of the plan that benefits noncollectively bargained employees. Thus, the mandatorily disaggregated portion of the plan that benefits the collectively bargained employees automatically satisfies this paragraph (b)(7) for the plan year and hence section 410(b). See § 1.410(b)-9 for the definitions of collectively bargained employee and noncollectively bargained employee.

(c) Requirements with respect to former employees—(1) Former employees tested separately. Former employees are tested separately from employees for purposes of section 410(b). Thus, former employees are disregarded in applying the ratio percentage test, the nondiscriminatory classification test, and the average benefit percentage test with respect to the coverage of employees under a plan, and employees are disregarded in applying this section with respect to the coverage of former employees under a plan.

(2) Testing former employees. A plan satisfies section 410(b) with respect to former employees if and only if, under all of the relevant facts and circumstances (including the group of nonexcludable former employees not benefiting under the plan), the group of former employees benefiting under the plan does not discriminate significantly in favor of highly compensated former employees.

(d) Nonelective contributions under section 403(b) plans. For plan years beginning on or after January 1, 1989, a plan subject to section 403(b)(12)(A)(i) with respect to nonelective contributions (i.e., contributions not made pursuant to a salary reduction agreement) is treated as a plan subject to the requirements of this section. For this purpose, a plan described in the preceding sentence must satisfy the requirements of this section without regard to section 410(c) and paragraph (e) of this section. For plan years beginning before the effective date set forth in § 1.410(b)-10(d), any plan described in section 410(c)(1)(A) (regarding governmental plans) satisfies the requirements of this section.

(e) Certain governmental and church plans. The requirements of section 410(b) do not apply to a plan described in section 410(c)(1) (other than a plan subject to section 403(b)(12)(A)(i) or a plan with respect to which an election has been made under section 410(d)). Such a plan must satisfy section 401(a)(3) as in effect on September 1, 1974. For this purpose, a plan that satisfies section 410(b) (without regard to this paragraph (e)) is treated as satisfying section 401(a)(3) as in effect on September 1, 1974. For plan years beginning before the effective date set forth in § 1.410(b)-10(d), any plan described in section 410(c)(1)(A) (regarding governmental plans) satisfies the requirements of this section and is thus treated as satisfying the requirements of section 401(a)(3) as in effect on September 1, 1974. See § 1.410(b)-10(b)(2) for a special rule for plans of tax-exempt organizations.

(f) Certain acquisitions or dispositions. Section 410(b)(6)(C) (relating to certain acquisitions or dispositions) provides a special rule whereby a plan may be treated as satisfying section 410(b) for a limited period of time after an acquisition or disposition if it satisfies section 410(b) (without regard to the special rule) immediately before the acquisition or disposition and there is no significant change in the plan or in the coverage of the plan other than the acquisition or disposition. For purposes of section 410(b)(6)(C) and this paragraph (f), the terms “acquisition” and “disposition” refer to an asset or stock acquisition, merger, or other similar transaction involving a change in employer of the employees of a trade or business.

(g) Additional rules. The Commissioner may, in revenue rulings, notices, and other guidance of general applicability, provide any additional rules that may be necessary or appropriate in applying the minimum coverage requirements of section 410(b), including (without limitation) additional rules limiting or expanding the methods in § 1.410(b)-5(d) and (e) for determining employee benefit percentages.

(a) Employees benefiting under a plan—(1) In general. Except as provided in paragraph (a)(2) of this section, an employee is treated as benefiting under a plan for a plan year if and only if for that plan year, in the case of a defined contribution plan, the employer receives an allocation taken into account under § 1.401(a)(4)-2(c)(2)(ii), or in the case of a defined benefit plan, the employee has an increase in a benefit accrued or treated as an accrued benefit under section 411(d)(6).

(2) Exceptions to allocation or accrual requirement—(i) Section 401(k) and 401(m) plans. Notwithstanding paragraph (a)(1) of this section, an employee is treated as benefiting under a section 401(k) plan for a plan year if and only if the employee is an eligible employee as defined in § 1.401(k)-6 under the plan. Similarly, an employee is treated as benefiting under a section 401(m) plan for a plan year if and only if the employee is an eligible employee as defined in § 1.401(m)-5 under the plan for the plan year.

(ii) Section 415 limits—(A) General rule for defined benefit plans. In determining whether an employee is treated as benefiting under a defined benefit plan for a plan year, plan provisions that implement the limits of section 415 are disregarded. Any plan provision that provides for increases in an employee's accrued benefit under the plan due solely to adjustments under section 415(d)(1), additional years of participation or service under section 415(b)(5), or changes in the defined contribution fraction under section 415(e) is also disregarded, but only if such provision applies uniformly to all employees in the plan.

(B) Defined benefit plans taking section 415 limits into account under section 401(a)(4) testing. Paragraph (a)(2)(ii)(A) of this section does not apply in the case of a defined benefit plan that uses the option in § 1.401(a)(4)-3(d)(2)(ii)(B) to take into account plan provisions implementing the provisions of section 415 in determining accrual rates under the section 401(a)(4) general test.

(C) Defined contribution plans. A defined contribution plan is permitted to apply the rule in the first sentence of paragraph (a)(2)(ii)(A) of this section in determining whether an employee is treated as benefiting under the plan, provided it applies the rule on a consistent basis for all employees in the plan.

(iii) Certain employees treated as benefiting—(A) In general. An employee is treated as benefiting under a plan for a plan year if the employee satisfies all of the applicable conditions for accruing a benefit or receiving an allocation for the plan year but fails to have an increase in accrued benefit or to receive an allocation solely because of one or more of the conditions set forth in paragraphs (a)(2)(iii) (B) through (F) of this section.

(B) Certain plan limits. The employee's benefit would otherwise exceed a limit that is applicable on a uniform basis to all employees in the plan. Thus, for example, if the formula under a defined benefit plan takes into account only the first 30 years of service for accrual purposes, an employee who has completed more than 30 years of service is still treated as benefiting under the plan.

(C) Benefits previously accrued. The benefit previously accrued by the employee is greater than the benefit that would be determined under the plan if the benefit previously accrued were disregarded. This could happen, for example, when the plan is applying the wear-away formula of § 1.401(a)(4)-13(c)(4)(ii) and the employee's frozen accrued benefit exceeds the benefit determined under the current formula.

(D) Benefit offset arrangements. The plan offsets the employee's current benefit accrual under an offset arrangement described in § 1.401(a)(4)-3(f)(9) (without regard to whether the offset is attributable to pre-participation service or past service).

(E) Target benefit plans. In the case of a target benefit plan that satisfies the nondiscriminatory amount requirement of § 1.401(a)(4)-1(b)(2) by satisfying the safe harbor in § 1.401(a)(4)-8(b)(3), the employee's theoretical reserve is greater than or equal to the actuarial present value of the fractional rule benefit.

(F) Post-normal retirement age adjustments. The employee has attained normal retirement age under a defined benefit plan and fails to accrue a benefit because of the provisions of section 411(b)(1)(H)(iii) regarding adjustments for delayed retirement.

(iv) Section 412(i) plans—(A) General rule. Notwithstanding paragraph (a)(1) of this section, an employee is treated as benefiting under an insurance contract plan within the meaning of section 412(i) for a plan year if and only if a premium is paid on behalf of the employee for the plan year.

(B) Exceptions. Notwithstanding paragraph (a)(2)(iv)(A) of this section, an employee is treated as benefiting under an insurance contract plan within the meaning of section 412(i) for a plan year if the sole reason that a premium is not paid on behalf of the employee is one of the reasons described in paragraph (a)(2)(iii) of this section. In addition, an employee is treated as benefiting under an insurance contract plan, within the meaning of section 412(i), that is a defined benefit plan if a premium is not paid on behalf of the employee solely because the insurance contracts that have previously been purchased on behalf of the employee guarantee to provide for the employee's projected normal retirement benefit without regard to future premium payments.

(3) Examples. The following examples illustrate the determination of whether an employee is benefiting under a plan for purposes of section 410(b).

(b) Former employees benefiting under a plan—(1) In general. A former employee is treated as benefiting for a plan year if and only if the plan provides an allocation or benefit increase described in paragraph (a)(1) of this section to the former employee for the plan year. Thus, for example, a former employee benefits under a defined benefit plan for a plan year if the plan is amended to provide an ad hoc cost-of-living adjustment in the former employee's benefits. In contrast, because an increase in benefits payable under a plan pursuant to an automatic cost-of-living provision adopted and effective before the beginning of the plan year is previously accrued, a former employee is not treated as benefiting in a subsequent plan year merely because the former employee receives an increase pursuant to such an automatic cost-of-living provision. Any accrual or allocation for an individual during the plan year that arises from the individual's status as an employee is treated as an accrual or allocation of an employee. Similarly, any accrual or allocation for an individual during the plan year that arises from the individual's status as a former employee is treated as an accrual or allocation of a former employee. It is possible for an individual to accrue a benefit both as an employee and as a former employee in a given plan year. During the plan year in which an individual ceases performing services for the employer, the individual is treated as an employee in applying section 410(b) with respect to employees and is treated as a former employee in applying section 410(b) with respect to former employees.

(2) Examples. The following examples illustrate the determination of whether a former employee benefits under a plan for purposes of section 410(b).

(a) In general. A plan satisfies the nondiscriminatory classification test of this section for a plan year if and only if, for the plan year, the plan benefits the employees who qualify under a classification established by the employer in accordance with paragraph (b) of this section, and the classification of employees is nondiscriminatory under paragraph (c) of this section.

(b) Reasonable classification established by the employer. A classification is established by the employer in accordance with this paragraph (b) if and only if, based on all the facts and circumstances, the classification is reasonable and is established under objective business criteria that identify the category of employees who benefit under the plan. Reasonable classifications generally include specified job categories, nature of compensation (i.e., salaried or hourly), geographic location, and similar bona fide business criteria. An enumeration of employees by name or other specific criteria having substantially the same effect as an enumeration by name is not considered a reasonable classification.

(c) Nondiscriminatory classification—(1) General rule. A classification is nondiscriminatory under this paragraph (c) for a plan year if and only if the group of employees included in the classification benefiting under the plan satisfies the requirements of either paragraph (c)(2) or (c)(3) of this section for the plan year.

(2) Safe harbor. A plan satisfies the requirement of this paragraph (c)(2) for a plan year if and only if the plan's ratio percentage is greater than or equal to the employer's safe harbor percentage, as defined in paragraph (c)(4)(i) of this section. See § 1.410(b)-9 for the definition of a plan's ratio percentage.

(3) Facts and circumstances—(i) General rule. A plan satisfies the requirements of this paragraph (c)(3) if and only if—

(A) The plan's ratio percentage is greater than or equal to the unsafe harbor percentage, as defined in paragraph (c)(4)(ii) of this section, and

(B) The classification satisfies the factual determination of paragraph (c)(3)(ii) of this section.

(ii) Factual determination. A classification satisfies this paragraph (c)(3)(ii) if and only if, based on all the relevant facts and circumstances, the Commissioner finds that the classification is nondiscriminatory. No one particular fact is determinative. Included among the facts and circumstances relevant in determining whether a classification is nondiscriminatory are the following—

(A) The underlying business reason for the classification. The greater the business reason for the classification, the more likely the classification is to be nondiscriminatory. Reducing the employer's cost of providing retirement benefits is not a relevant business reason.

(B) The percentage of the employer's employees benefiting under the plan. The higher the percentage, the more likely the classification is to be nondiscriminatory.

(C) Whether the number of employees benefiting under the plan in each salary range is representative of the number of employees in each salary range of the employer's workforce. In general, the more representative the percentages of employees benefiting under the plan in each salary range, the more likely the classification is to be nondiscriminatory.

(D) The difference between the plan's ratio percentage and the employer's safe harbor percentage. The smaller the difference, the more likely the classification is to be nondiscriminatory.

(E) The extent to which the plan's average benefit percentage (determined under § 1.410(b)-5) exceeds 70 percent.

(4) Definitions—(i) Safe harbor percentage. The safe harbor percentage of an employer is 50 percent, reduced by 3/4 of a percentage point for each whole percentage point by which the nonhighly compensated employee concentration percentage exceeds 60 percent. See paragraph (c)(4)(iv) for a table that illustrates the safe harbor percentage and unsafe harbor percentage.

(ii) Unsafe harbor percentage. The unsafe harbor percentage of an employer is 40 percent, reduced by 3/4 of a percentage point for each whole percentage point by which the nonhighly compensated employee concentration percentage exceeds 60 percent. However, in no case is the unsafe harbor percentage less than 20 percent.

(iii) Nonhighly compensated employee concentration percentage. The nonhighly compensated employee concentration percentage of an employer is the percentage of all the employees of the employer who are nonhighly compensated employees. Employees who are excludable employees for purposes of the average benefit test are not taken into account.

(iv) Table. The following table sets forth the safe harbor and unsafe harbor percentages at each nonhighly compensated employee concentration percentage:

(5) Examples. The following examples illustrate the rules in this paragraph (c).

(a) General rule. A plan satisfies the average benefit percentage test of this section for a plan year if and only if the average benefit percentage of the plan for the plan year is at least 70 percent. A plan is deemed to satisfy this requirement if it satisfies paragraph (f) of this section for the plan year.

(b) Determination of average benefit percentage. The average benefit percentage of a plan for a plan year is the percentage determined by dividing the actual benefit percentage of the nonhighly compensated employees in plans in the testing group for the testing period that includes the plan year by the actual benefit percentage of the highly compensated employees in plans in the testing group for that testing period. See paragraph (d)(3)(ii) of this section for the definition of testing period.

(c) Determination of actual benefit percentage. The actual benefit percentage of a group of employees for a testing period is the average of the employee benefit percentages, calculated separately with respect to each of the employees in the group for the testing period. All nonexcludable employees of the employer are taken into account for this purpose, even if they are not benefiting under any plan that is taken into account.

(d) Determination of employee benefit percentages—(1) Overview. This paragraph (d) provides rules for determining employee benefit percentages. See paragraph (e) of this section for alternative methods for determining employee benefit percentages.

(2) Employee contributions and employee-provided benefits disregarded. Only employer-provided contributions and benefits are taken into account in determining employee benefit percentages. Therefore, employee contributions (including both employee contributions allocated to separate accounts and employee contributions not allocated to separate accounts), and benefits derived from such contributions, are not taken into account in determining employee benefit percentages.

(3) Plans and plan years taken into account—(i) Testing group. All plans included in the testing group under § 1.410(b)-7(e)(1), and only those plans, are taken into account in determining an employee's employee benefit percentage.

(ii) Testing period. An employee's employee benefit percentage is determined on the basis of plan years ending with or within the same calendar year. These plan years are referred to in this section as the relevant plan years or, in the aggregate, as the testing period.

(4) Contributions or benefits basis. Employee benefit percentages may be determined on either a contributions or a benefits basis. Employee benefit percentages for any testing period must be determined on the same basis (contributions or benefits) for all plans in the testing group.

(5) Determination of employee benefit percentage—(i) General rule. The employee benefit percentage for an employee for a testing period is the rate that would be determined for that employee for purposes of applying the general test for nondiscrimination in §§ 1.401(a)(4)-2, 1.401(a)(4)-3, 1.401(a)(4)-8 or 1.401(a)(4)-9, if all the plans in the testing group were aggregated for purposes of section 410(b). Thus, if employee benefit percentages are determined on a contributions basis, each employee's employee benefit percentage is the aggregate normal allocation rate that would be determined for the employee under § 1.401(a)(4)-9(b)(2)(ii)(A) (if the plans in the testing group include both defined benefit and defined contribution plans), the allocation rate that would be determined for the employee under § 1.401(a)(4)-2(c)(2) (if the plans in the testing group include only defined contribution plans), or the equivalent normal allocation rate that would be determined for the employee under § 1.401(a)(4)-8(c)(2) (if the plans in the testing group include only defined benefit plans). Similarly, if employee benefit percentages are determined on a benefits basis, each employee's employee benefit percentage is the aggregate normal accrual rate that would be determined for the employee under § 1.401(a)(4)-9(b)(2)(ii)(B), the normal accrual rate that would be determined for the employee under § 1.401(a)(4)-3(d), or the equivalent accrual rate that would be determined for the employee under § 1.401(a)(4)-8(b)(2), depending on whether the plans in the testing group include both defined benefit and defined contribution plans, only defined benefit plans, or only defined contribution plans.

(ii) Plans with differing plan years. If not all the plans in the testing group share the same plan year, § 1.410(b)-7(d)(5) would ordinarily prohibit them from being aggregated for purposes of section 410(b). In such a case, employee benefit percentages are determined by applying the rules of paragraph (d)(5)(i) of this section separately to each subset of plans in the testing group that share the same plan year (or the same accrual computation period) and aggregating the results for all plans in the testing group. Thus, an employee's employee benefit percentage is determined as the sum of these separate employee benefit percentages that are determined consistently for all the plans in the testing group (except for differences attributable solely to the differences in plan years).

(iii) Options and consistency requirements. In determining employee benefit percentages under this paragraph (d)(5), any optional or alternative methods or rules available for determining rates in §§ 1.401(a)(4)-2, 1.401(a)(4)-3, 1.401(a)(4)-8, or 1.401(a)(4)-9, whichever is applicable, may be applied. Thus, for example, employee benefit percentages may generally be calculated using any of the alternative methods of determining average annual compensation or plan year compensation under § 1.401(a)(4)-12, and using any underlying definition of compensation that satisfies section 414(s). Except as otherwise specifically permitted, the determination of employee benefit percentages must be made on a consistent basis for all employees and for all plans in the testing group as required by §§ 1.401(a)(4)-2(c)(2)(vi), 1.401(a)(4)-3(d)(2)(i), 1.401(a)(4)-8(b)(2)(iv), 1.401(a)(4)-8(c)(2)(iv) or 1.401(a)(4)-9(b)(2)(iv).

(6) Permitted disparity—(i) In general. Permitted disparity may be imputed in determining employee benefit percentages as provided in §§ 1.401(a)(4)-2, 1.401(a)(4)-3, 1.401(a)(4)-8, or 1.401(a)(4)-9, whichever is applicable. When separate employee benefit percentages are determined for individual plans under paragraph (e)(2) of this section (or for subsets of plans that have the same plan year as described in paragraph (d)(5)(ii) of this section), permitted disparity may be imputed for an employee only in one individual plan (or subset of plans) and may not be imputed for the same employee in another individual plan (or subset of plans). However, if the same average annual compensation or plan year compensation is used to determine employee benefit percentages in more than one plan, the employee's employee benefit percentages for those plans may be summed prior to imputing permitted disparity.

(ii) Plans which may not use permitted disparity. Permitted disparity may be reflected in the determination of rates only to the extent that the plans for which rates are being determined are plans for which the permitted disparity of section 401(l) is available. Thus, for example, if a section 401(k) plan is included in the testing group and permitted disparity is imputed under § 1.401(a)(4)-2(c)(iv), then employee benefit percentages are determined by first calculating an adjusted allocation rate (within the meaning of § 1.401(a)(4)-7(b)(1)) without regard to the amount of allocations under the section 401(k) plan and adding to it the allocation rate for the section 401(k) plan. See § 1.401(l)-1(a)(4) for a list of types of plans for which permitted disparity is not available.

(7) Requirements for certain plans providing early retirement benefits—(i) General rule. If any defined benefit plan in the testing group provides for early retirement benefits in addition to normal retirement benefits to any highly compensated employee, and the average actuarial reduction for any one of these benefits commencing in the five years prior to the plan's normal retirement age is less than four percent per year, then the aggregate most valuable allocation rate, equivalent most valuable allocation rate, aggregate most valuable accrual rate, or most valuable accrual rate must be substituted for the related normal rates in paragraph (d)(5) of this section.

(ii) Exception. Paragraph (d)(7)(i) of this section does not apply if early retirement benefits with average actuarial reductions described in that paragraph are currently available, within the meaning of § 1.401(a)(4)-4(b), under plans in the testing group to a percentage of nonhighly compensated employees that is at least 70 percent of the percentage of highly compensated employees to whom these benefits are currently available.

(e) Additional optional rules—(1) Overview. This paragraph (e) contains various alternative methods for determining employee benefit percentages for a testing period.

(2) Determination of employee benefit percentages as the sum of separately determined rates—(i) In general. Employee benefit percentages may be determined as the sum of separately determined employee benefit percentages for each of the plans in the testing group that are aggregated under paragraphs (d)(5) (i) or (ii) of this section, provided that these employee benefit percentages are determined on a consistent basis for all of these plans pursuant to paragraph (d)(5)(iii) of this section.

(ii) Exception from consistency requirement. The consistency requirement of paragraph (e)(2)(i) of this section is not violated merely because employee benefit percentages are not determined in a consistent manner for all of the plans in the testing group and the inconsistencies in determination of rates among plans are described in paragraph (e)(2)(iii) of this section. The exception in this paragraph (e)(2)(ii) applies only if it is reasonable to believe that the inconsistencies do not result in an average benefit percentage that is significantly higher than the average benefit percentage that would be determined had employee benefit percentages been determined on a consistent basis pursuant to paragraph (d)(5)(iii) of this section.

(iii) Permitted inconsistencies. The following inconsistencies between plans are permitted under this paragraph (e)(2)—

(A) Use of different underlying definitions of section 414(s) compensation in the determination of rates;

(B) Use of different definitions of average annual compensation;

(C) Use of different testing ages;

(D) Use of different fresh-start dates;

(E) Use of different actuarial assumptions for normalization; or

(F) Disregard of actuarial increases after normal retirement age and QPSA charges without regard to any requirement for uniformity in the actuarial increases or QPSA charges.

(3) Determination of employee benefit percentages without regard to plans of another type—(i) General rule. Employee benefit percentages may be determined under plans of one type (i.e., defined benefit plans or defined contribution plans) by treating all plans of the other type (i.e., defined contribution plans or defined benefit plans, respectively) as if they were not part of the testing group, using the method provided in this paragraph (e)(3). If this method is used to determine whether a defined contribution plan satisfies the average benefit percentage test, employee benefit percentages under all defined contribution plans in the testing group must be determined on a contributions basis, and benefits under any defined benefit plans may not be included in the employee benefit percentage. Similarly, if this method is used to determine whether a defined benefit plan satisfies the average benefit percentage test, employee benefit percentages under all defined benefit plans in the testing group must be determined on a benefits basis, and allocations under any defined contribution plans may not be included in the employee benefit percentage.

(ii) Restriction on use of separate testing group determination method. A plan does not satisfy the average benefit percentage test using the method provided in this paragraph (e)(3) unless each of the plans in the testing group of the other type (i.e., defined benefit plan or defined contribution plan) than the plan being tested satisfies the average benefit test of § 1.410(b)-2(b)(3) using the method in this paragraph (e)(3) or satisfies the ratio percentage test of § 1.410(b)-2(b)(2).

(iii) Treatment of permitted disparity. Although under the general rule of this paragraph (e)(3) plans of another type are disregarded in determining employee benefit percentages, the permitted disparity used by those plans (including any permitted disparity that is used by those plans to satisfy § 1.401(a)(4)-1(b)(2)) is nonetheless taken into account in determining the extent to which permitted disparity may be used in determining employee benefit percentages.

(iv) Example. The following example illustrates the rules of this paragraph (e)(3):

(4) Simplified method for determining employee benefit percentages for certain defined benefit plans—(i) In general. An employee's employee benefit percentage with respect to a plan may be determined under the simplified method of paragraph (e)(4)(ii) of this section, provided the following conditions are satisfied:

(A) The only plans included in the testing group are defined benefit plans, and employee benefit percentages under these plans are determined on a benefits basis.

(B) Employee benefit percentages under the plans in the testing group are not required to be determined by taking into account early retirement benefits under paragraph (d)(7) of this section.

(C) The plan is a safe harbor defined benefit plan described in § 1.401(a)(4)-3(b).

(ii) Simplified method—(A) Section 401(l) plans. Under the simplified method of this paragraph (e)(4)(ii), an employee's employee benefit percentage with respect to a section 401(l) plan described in § 1.401(a)(4)-3(b)(3) (i.e., a unit credit plan) may be deemed equal to the employee's excess benefit percentage or gross benefit percentage (as defined in § 1.401(l)-1(c) (14) or (18), respectively), whichever is applicable under the plan's benefit formula in the plan year. In the case of a section 401(l) plan described in § 1.401(a)(4)-3(b)(4) (i.e., a fractional accrual plan), an employee's employee benefit percentage with respect to that plan may be deemed equal to the rate at which the excess or gross benefit, whichever is applicable, accrues for the employee in the plan year, taking into account the plan's benefit formula and the employee's projected service at normal retirement age. The use of this simplified method will be treated as an imputation of permitted disparity. See paragraph (d)(6) of this section for a restriction on multiple use of permitted disparity.

(B) Other plans. Under the simplified method of this paragraph (e)(4)(ii), an employee's employee benefit percentage with respect to a plan described in § 1.401(a)(4)-3(b)(3) that is not a section 401(l) plan and that is not imputing permitted disparity may be deemed equal to the employee's benefit rate in the plan year under the plan's benefit formula. In the case of a plan described in § 1.401(a)(4)-3(b)(4) that is not a section 401(l) plan and that is not imputing permitted disparity, an employee's employee benefit percentage with respect to that plan may be deemed equal to the rate at which the benefit accrues for the employee in the plan year, taking into account the plan's benefit formula and an employee's projected service at normal retirement age.

(5) Three-year averaging period. An employee's employee benefit percentage may be determined for a testing period as the average of the employee's employee benefit percentages determined separately for the testing period and for the immediately preceding one or two testing periods (referred to in this section as an averaging period). Employee benefit percentages of a particular employee that are averaged together within an averaging period must be determined on a consistent basis for all testing periods within the averaging period.

(6) Alternative methods of determining compensation. Employee benefit percentages may be determined on the basis of any definition of compensation that satisfies § 1.414(s)-1(d) (without regard to whether the definition satisfies § 1.414(s)-1(d)(3)), provided that the same definition is used for all employees and it is reasonable to believe that the definition does not result in an average benefit percentage that is significantly higher than the average benefit percentage that would be determined had employee benefit percentages been determined using a definition of compensation that also satisfies § 1.414(s)-1(d)(3).

(f) Special rule for certain collectively bargained plans. A plan (as determined without regard to the mandatory disaggregation rule of § 1.410(b)-7(c)(5)) that benefits both collectively bargained employees and noncollectively bargained employees is deemed to satisfy the average benefit percentage test of this section if—

(1) The provisions of the plan applicable to each employee in the plan are identical to the provisions of the plan applicable to every other employee in the plan, including the plan benefit or allocation formula, any optional forms of benefit, any ancillary benefit, and any other right or feature under the plan, and

(2) The plan would satisfy the ratio percentage test of § 1.410(b)-2(b)(2), if §§ 1.410(b)-6(d) and 1.410(b)-7(c)(5) (the excludable employee and mandatory disaggregation rules for collectively bargained and noncollectively bargained employees) did not apply.

(a) Employees—(1) In general. For purposes of applying section 410(b) with respect to employees, all employees of the employer, other than the excludable employees described in paragraphs (b) through (i) of this section, are taken into account. Excludable employees are not taken into account with respect to a plan even if they are benefiting under the plan, except as otherwise provided in paragraph (b) of this section.

(2) Rules of application. Except as specifically provided otherwise, excludable employees are determined separately with respect to each plan for purposes of testing that plan under section 410(b). Thus, in determining whether a particular plan satisfies the ratio percentage test of § 1.410(b)-2(b)(2), paragraphs (b) through (i) of this section are applied solely with reference to that plan. Similarly, in determining whether two or more plans that are permissively aggregated and treated as a single plan under § 1.410(b)-7(d) satisfy the ratio percentage test of § 1.410(b)-2(b)(2), paragraphs (b) through (i) of this section are applied solely with reference to the deemed single plan. In determining whether a plan satisfies the average benefit percentage test of § 1.410(b)-5, the rules of this section are applied by treating all plans in the testing group as a single plan.

(b) Minimum age and service exclusions—(1) In general. If a plan applies minimum age and service eligibility conditions permissible under section 410(a)(1) and excludes all employees who do not meet those conditions from benefiting under the plan, then all employees who fail to satisfy those conditions are excludable employees with respect to that plan. An employee is treated as meeting the age and service requirements on the date that any employee with the same age and service (including service permitted to be taken into account for purposes of nondiscrimination testing under § 1.401(a)(4)-11(d)(3)) would be eligible to commence participation in the plan, as provided in section 410(b)(4)(C).

(2) Multiple age and service conditions. If a plan, including a plan for which an employer chooses the treatment under paragraph (b)(3) of this section, has two or more different sets of minimum age and service eligibility conditions, those employees who fail to satisfy all of the different sets of age and service conditions are excludable employees with respect to the plan. Except as provided in paragraph (b)(3) of this section, an employee who satisfies any one of the different sets of conditions is not an excludable employee with respect to the plan. Differences in the manner in which service is credited (e.g., hours of service calculated in accordance with 29 CFR 2530.200b-2 for hourly employees and elapsed time calculated in accordance with § 1.410(a)-7 for salaried employees) for purposes of applying a service condition are not taken into account in determining whether multiple age and service eligibility conditions exist.

(3) Plans benefiting certain otherwise excludable employees—(i) In general. An employer may treat a plan benefiting otherwise excludable employees as two separate plans, one for the otherwise excludable employees and one for the other employees benefiting under the plan. See § 1.410(b)-7(c)(3) regarding permissive disaggregation of plans benefiting otherwise excludable employees. The effect of this rule is that employees who would be excludable under paragraph (b)(1) of this section (applied without regard to section 410(a)(1)(B)) but for the fact that the plan does not apply the greatest permissible minimum age and service conditions may be treated as excludable employees with respect to the plan. This treatment is available only if the plan satisfies section 410(b) and § 1.410(b)-2 with respect to these otherwise excludable employees in the manner described in paragraph (b)(3)(ii) of this section.

(ii) Testing portion of plan benefiting otherwise excludable employees. In determining whether the plan that benefits employees who would otherwise be excludable under paragraph (b)(1) of this section (applied without regard to section 410(a)(1)(B)) satisfies section 410(b) and § 1.410(b)-2, employees who have satisfied the greatest permissible minimum age and service conditions with respect to the plan are excludable employees. In addition, if the plan being tested applies minimum age and service conditions and those conditions are less than the maximum permissible minimum age and service conditions, employees who have not satisfied the lower minimum age and service conditions actually provided for in the plan are excludable employees. Thus, for example, if the plan requires attainment of age 18 and 3 months of service, employees who have not attained age 18 or 3 months of service with the employer are excludable employees.

(4) Examples. The following examples illustrate the minimum age and service condition rules of this paragraph (b). In each example, the employer is not treated as operating qualified separate lines of business under section 414(r).

(c) Certain nonresident aliens—(1) General rule. An employee who is a nonresident alien (within the meaning of section 7701(b)(1)(B)) and who receives no earned income (within the meaning of section 911(d)(2)) from the employer that constitutes income from sources within the United States (within the meaning of section 861(a)(3)) is treated as an excludable employee.

(2) Special treaty rule. In addition, an employee who is a nonresident alien (within the meaning of section 7701(b)(1)(B)) and who does receive earned income (within the meaning of section 911(d)(2)) from the employer that constitutes income from sources within the United States (within the meaning of section 861(a)(3)) is permitted to be excluded, if all of the employee's earned income from the employer from sources within the United States is exempt from United States income tax under an applicable income tax convention. This paragraph (c)(2) applies only if all employees described in the preceding sentence are so excluded.

(d) Collectively bargained employees—(1) General rule. A collectively bargained employee is an excludable employee with respect to a plan that benefits solely noncollectively bargained employees. If a plan (within the meaning of § 1.410(b)-7(b)) benefits both collectively bargained employees and noncollectively bargained employees for a plan year, § 1.410(b)-7(c)(4) provides that the portion of the plan that benefits the collectively bargained employees is treated as a separate plan from the portion of the plan that benefits the noncollectively bargained employees. Thus, a collectively bargained employee is always an excludable employee with respect to the mandatorily disaggregated portion of any plan that benefits noncollectively bargained employees.

(2) Definition of collectively bargained employee—(i) In general. A collectively bargained employee is an employee who is included in a unit of employees covered by an agreement that the Secretary of Labor finds to be a collective bargaining agreement between employee representatives and one or more employers, provided that there is evidence that retirement benefits were the subject of good faith bargaining between employee representatives and the employer or employers. An employee is a collectively bargained employee regardless of whether the employee benefits under any plan of the employer. See section 7701(a)(46) and § 301.7701-17T of this chapter for additional requirements applicable to the collective bargaining agreement. An employee who performs hours of service during the plan year as both a collectively bargained employee and a noncollectively bargained employee is treated as a collectively bargained employee with respect to the hours of service performed as a collectively bargained employee and a noncollectively bargained employee with respect to the hours of service performed as a noncollectively bargained employee. See § 1.410(b)-7(c) for disaggregation rules for plans benefiting collectively bargained and noncollectively bargained employees.

(ii) Special rules for certain employees in multiemployer plans—(A) In general. For purposes of this paragraph (d), in testing the disaggregated portion of a multiemployer plan benefiting noncollectively bargained employees, a noncollectively bargained employee who benefits under the plan may be treated as a collectively bargained employee with respect to all of the employee's hours of service under the rules of paragraphs (d)(2)(ii) (B) through (E) of this section, if the employee is or was a member of a unit of employees covered by a collective bargaining agreement and that agreement or a successor agreement provides for the employee to benefit under the plan in the current plan year. For this purpose, provisions of a participation agreement or similar document are taken into account in determining whether a collective bargaining agreement provides for an employee to benefit under a multiemployer plan.

(B) Employees who were collectively bargained employees during a portion of the current plan year. An employee described in paragraph (d)(2)(ii)(A) of this section who performs services for one or more employers that are parties to the collective bargaining agreement, for the plan, or for the employee representative both as a collectively bargained employee and as a noncollectively bargained employee during a plan year may be treated as a collectively bargained employee for the plan year, provided that at least half of the employee's hours of service during the plan year are performed as a collectively bargained employee.

(C) Employees who were collectively bargained employees during the collective bargaining agreement. An employee described in paragraph (d)(2)(ii)(A) of this section who was a collectively bargained employee with respect to all of the employee's hours of service during a plan year (including employees who are treated as collectively bargained employees with respect to all of their hours of service during a plan year under paragraph (d)(2)(ii) (B) or (E) of this section) may be treated as a collectively bargained employee with respect to all of the employee's hours of service for the duration of the collective bargaining agreement applicable for such plan year or, if later, until the end of the following plan year. For this purpose, a collective bargaining agreement is applicable for a plan year if it provided for the employee to benefit in the plan and was effective for any portion of that plan year. This paragraph (d)(2)(ii)(C) does not apply unless the terms of the plan providing for benefit accruals treat the employee in a manner that is generally no more favorable than similarly-situated employees who are collectively bargained employees.

(D) Employees who previously were collectively bargained employees. An employee who was treated as a collectively bargained employee pursuant to paragraph (d)(2)(ii)(C) of this section may be treated as a collectively bargained employee with respect to all of the employee's hours of service after the end of the period described in paragraph (d)(2)(ii)(C) of this section, provided that the employee is performing services for one or more employers that are parties to the collective bargaining agreement, for the plan, or for the employee representative. This paragraph (d)(2)(ii)(D) does not apply unless the terms of the plan providing for benefit accruals treat the employee in a manner that is generally no more favorable than similarly-situated employees who are collectively bargained employees, and no more than five percent of the employees covered under the multiemployer plan are noncollectively bargained employees (determined without regard to this paragraph (d)(2)(ii)(D)). In determining whether more than five percent of the employees covered under the multiemployer plan are noncollectively bargained employees, those employees who are described in paragraphs (d)(2)(ii) (B) and (C) of this section are treated as collectively bargained employees.

(E) Transition rule. For a plan year beginning before the applicable effective date of these regulations as set forth in § 1.410(b)-10 (b) or (d), any employee described in paragraph (d)(2)(ii)(A) of this section may be treated as a collectively bargained employee with respect to all of the employee's hours of service for that plan year.

(F) Consistency requirement. The rules in paragraphs (d)(2) (i) and (ii) of this section must be applied to all employees on a reasonable and consistent basis for the plan year.

(iii) Covered by a collective bargaining agreement—(A) General rule. For purposes of paragraph (d)(2)(i) of this section, an employee is included in a unit of employees covered by a collective bargaining agreement if and only if the employee is represented by a bona fide employee representative that is a party to the collective bargaining agreement under which the plan is maintained. Thus, for example, an employee of either a plan or the employee representative that is a party to the collective bargaining agreement under which the plan is maintained is not included in a unit of employees covered by the collective bargaining agreement under which the plan is maintained merely because the employee is covered under the plan pursuant to an agreement entered into by the plan or employee representative on behalf of the employee (other than in the capacity of an employee representative with respect to the employee). This is the case even if all of such employees benefiting under the plan constitute only a de minimis percentage of the total employees benefiting under the plan.

(B) Plans covering professional employees—(1) In general. An employee is not considered included in a unit of employees covered by a collective bargaining agreement for a plan year for purposes of paragraph (d)(2)(iii)(A) of this section if, for the plan year, more than 2 percent of the employees who are covered pursuant to the agreement are professionals. This rule applies to all employees under the agreement, nonprofessionals as well as professionals. Thus, no employees covered by such an agreement are excludable employees with respect to employees who are not covered by a collective bargaining agreement.

(2) Multiple collective bargaining agreements. This paragraph (d)(2)(iii)(B) is applied separately with respect to each collective bargaining agreement. Thus, for example, if a plan benefits two groups of employees, one included in a unit of employees covered by collective bargaining agreement X, more than 2 percent of whom are professionals, and another included in a unit of employees covered by collective bargaining agreement Y, none of whom are professionals, the group covered by agreement X is not considered covered by a collective bargaining agreement and the group covered by agreement Y is considered covered by a collective bargaining agreement.

(3) Application of minimum coverage tests. If a plan covers more than 2 percent professional employees, no employees in the plan are treated as covered by a collective bargaining agreement. A plan that covers more than 2 percent professional employees must satisfy section 410(b) without regard to section 413(b) and the special rule in § 1.410(b)-2(b)(7) of this section (regarding collectively bargained plans). In such cases, all nonexcludable employees must be taken into account. For this purpose, employees included in other collective bargaining units are excludable employees. However, the employees who are not covered by a collective bargaining agreement and the employees who are covered by an agreement that has more than 2 percent professionals are not excludable employees.

(iv) Examples. The following examples illustrate the collective bargaining unit rules of this section.

(e) Employees of qualified separate lines of business. If an employer is treated as operating qualified separate lines of business for purposes of section 410(b) in accordance with § 1.414(r)-1 (b), in testing a plan that benefits employees of one qualified separate line of business, the employees of the other qualified separate lines of business of the employer are treated as excludable employees. The rule in this paragraph (e) does not apply for purposes of satisfying the nondiscriminatory classification requirement of section 410(b)(5)(B). See §§ 1.414(r)-1(c)(2) and 1.414(r)-8 (separate application of section 410(b) to the employees of a qualified separate line of business). In addition, the rule in this paragraph (e) does not apply to a plan that is tested under the special rule for employer-wide plans in § 1.414(r)-1(c) (2) (ii) for a plan year.

(f) Certain terminating employees—(1) In general. An employee may be treated as an excludable employee for a plan year with respect to a particular plan if—

(i) The employee does not benefit under the plan for the plan year,

(ii) The employee is eligible to participate in the plan,

(iii) The plan has a minimum period of service requirement or a requirement that an employee be employed on the last day of the plan year (last-day requirement) in order for an employee to accrue a benefit or receive an allocation for the plan year,

(iv) The employee fails to accrue a benefit or receive an allocation under the plan solely because of the failure to satisfy the minimum period of service or last-day requirement,

(v) The employee terminates employment during the plan year with no more than 500 hours of service, and the employee is not an employee as of the last day of the plan year (for purposes of this paragraph (f)(1)(v), a plan that uses the elapsed time method of determining years of service may use either 91 consecutive calendar days or 3 consecutive calendar months instead of 500 hours of service, provided it uses the same convention for all employees during a plan year), and

(vi) If this paragraph (f) is applied with respect to any employee with respect to a plan for a plan year, it is applied with respect to all employees with respect to the plan for the plan year.

(2) Hours of service. For purposes of this paragraph (f), the term “hours of service” has the same meaning as provided for such term by 29 CFR 2530.200b-2 under the general method of crediting service for the employee. If one of the equivalencies set forth in 29 CFR 2530.200b-3 is used for crediting service under the plan, the 500-hour requirement must be adjusted accordingly.

(3) Examples. The following examples illustrate the provision of this paragraph (f).

(g) Employees of certain governmental or tax-exempt entities—(1) Plans covered. For purposes of testing either a section 401(k) plan, or a section 401(m) plan that is provided under the same general arrangement as a section 401(k) plan, an employer may treat as excludable those employees described in paragraphs (g)(2) and (3) of this section.

(2) Employees of governmental entities. Employees of governmental entities who are precluded from being eligible employees under a section 401(k) plan by reason of section 401(k)(4)(B)(ii) may be treated as excludable employees if more than 95 percent of the employees of the employer who are not precluded from being eligible employees by reason of section 401(k)(4)(B)(ii) benefit under the plan for the year.

(3) Employees of tax-exempt entities. Employees of an organization described in section 403(b)(1)(A)(i) who are eligible to make salary reduction contributions under section 403(b) may be treated as excludable with respect to a section 401(k) plan, or a section 401(m) plan that is provided under the same general arrangement as a section 401(k) plan, if—

(i) No employee of an organization described in section 403(b)(1)(A)(i) is eligible to participate in such section 401(k) plan or section 401(m) plan; and

(ii) At least 95 percent of the employees who are neither employees of an organization described in section 403(b)(1)(A)(i) nor employees of a governmental entity who are precluded from being eligible employees under a section 401(k) plan by reason of section 401(k)(4)(B)(ii) are eligible to participate in such section 401(k) plan or section 401(m) plan.

(h) Former employees—(1) In general. For purposes of applying section 410(b) with respect to former employees, all former employees of the employer are taken into account, except that the employer may treat a former employee described in paragraph (h)(2) or (h)(3) of this section as an excludable former employee. If either (or both) of the former employee exclusion rules under paragraphs (h)(2) and (h)(3) of this section is applied, it must be applied to all former employees for the plan year on a consistent basis.

(2) Employees terminated before a specified date. The employer may treat a former employee as excludable if—

(i) The former employee became a former employee either prior to January 1, 1984, or prior to the tenth calendar year preceding the calendar year in which the current plan year begins, and

(ii) The former employee became a former employee in a calendar year that precedes the earliest calendar year in which any former employee who benefits under the plan in the current plan year became a former employee.

(3) Previously excludable employees. The employer may treat a former employee as excludable if the former employee was an excludable employee (or would have been an excludable employee if these regulations had been in effect) under the rules of paragraphs (b) through (g) of this section during the plan year in which the former employee became a former employee. If the employer treats a former employee as excludable pursuant to this paragraph (h)(3), the former employee is not taken into account with respect to a plan even if the former employee is benefiting under the plan.

(i) Former employees treated as employees. An employer may treat as excludable employees all formerly nonhighly compensated employees who are treated as employees of the employer under § 1.410(b)-9 solely because they have increases in accrued benefits under a defined benefit plan that are based on ongoing service or compensation credits (including imputed service or compensation) after they cease to perform services for the employer.

(a) In general. This section provides a definition of “plan.” First, this section sets forth a definition of plan within the meaning of section 401(a) or 403(a). Then certain mandatory disaggregation and permissive aggregation rules are applied. The result is the definition of plan that applies for purposes of sections 410(b) and 401(a)(4). Thus, in general, the term “plan” as used in this section initially refers to a plan described in section 414(l) and to an annuity plan described in section 403(a), and the term “plan” as used in other sections under these regulations means the plan determined after application of this section. Paragraph (b) of this section provides that each single plan under section 414(l) is treated as a single plan for purposes of section 410(b). Paragraph (c) of this section describes the rules for certain plans that must be treated as comprising two or more separate plans, each of which is a single plan subject to section 410(b). Paragraph (d) of this section provides a rule permitting an employer to aggregate certain separate plans to form a single plan for purposes of section 410(b). Paragraph (e) of this section provides rules for determining the testing group of plans taken into account in determining whether a plan satisfies the average benefit percentage test of § 1.410(b)-5.

(b) Separate asset pools are separate plans. Each single plan within the meaning of section 414(l) is a separate plan for purposes of section 410(b). See § 1.414(l)-1(b). For example, if only a portion of the assets under a defined benefit plan is available, on an ongoing basis, to provide the benefits of certain employees, and the remaining assets are available only in certain limited cases to provide such benefits (but are available in all cases for the benefit of other employees), there are two separate plans. Similarly, the defined contribution portion of a plan described in section 414(k) is a separate plan from the defined benefit portion of that same plan. A single plan under section 414(l) is a single plan for purposes of section 410(b), even though the plan comprises separate written documents and separate trusts, each of which receives a separate determination letter from the Internal Revenue Service. A defined contribution plan does not comprise separate plans merely because it includes more than one trust, or merely because it provides for separate accounts and permits employees to direct the investment of the amounts allocated to their accounts. Further, a plan does not comprise separate plans merely because assets are separately invested in individual insurance or annuity contracts for employees.

(c) Mandatory disaggregation of certain plans—(1) Section 401(k) and 401(m) plans. The portion of a plan that is a section 401(k) plan and the portion that is not a section 401(k) plan are treated as separate plans for purposes of section 410(b). Similarly, the portion of a plan that is a section 401(m) plan and the portion that is not a section 401(m) plan are treated as separate plans for purposes of section 410(b). Thus, a plan that consists of elective contributions under a section 401(k) plan, employee and matching contributions under a section 401(m) plan, and contributions other than elective, employee, or matching contributions is treated as three separate plans for purposes of section 410(b). In addition, the portion of a plan that consists of contributions described in § 1.401(k)-2(a)(5) (i.e., contributions that fail to satisfy the allocation or compensation requirements applicable to elective contributions and are therefore required to be tested separately) and the portion of the plan that does not consist of such contributions are treated as separate plans for purposes of section 410(b). Similarly, the portion of a plan that consists of contributions described in § 1.410(m)-1(b)(4)(ii) (i.e., matching contributions that fail to satisfy the allocation and other requirements applicable to matching contributions and are therefore required to be tested separately) and the portion of the plan that does not consist of such contributions are treated as separate plans for purposes of section 410(b).

(2) ESOPs and non-ESOPs. The portion of a plan that is an ESOP and the portion of the plan that is not an ESOP are treated as separate plans for purposes of section 410(b), except as otherwise permitted under § 54.4975-11(e) of this Chapter.

(3) Plans benefiting otherwise excludable employees. If an employer applies section 410(b) separately to the portion of a plan that benefits only employees who satisfy age and service conditions under the plan that are lower than the greatest minimum age and service conditions permissible under section 410(a), the plan is treated as comprising separate plans, one benefiting the employees who have satisfied the lower minimum age and service conditions but not the greatest minimum age and service conditions permitted under section 410(a) and one benefiting employees who have satisfied the greatest minimum age and service conditions permitted under section 410(a). See § 410(b)-6(b)(3)(ii) for rules about testing otherwise excludable employees.

(4) Plans benefiting certain disaggregation populations of employees—(i) In general—(A) Single plan must be treated as separate plans. If a plan (i.e., a single plan within the meaning of section 414(l)) benefits employees of more than one disaggregation population, the plan must be disaggregated and treated as separate plans, each separate plan consisting of the portion of the plan benefiting the employees of each disaggregation population. See paragraph (c)(4)(ii) of this section for the definition of disaggregation population.

(B) Benefit accruals or allocations attributable to current status. Except as otherwise provided in paragraph (c)(4)(i)(C) of this section, in applying the rule of paragraph (c)(4)(i)(A) of this section, the portion of the plan benefiting employees of a disaggregation population consists of all benefits accrued by, or all allocations made to, employees while they were members of the disaggregation population.

(C) Exceptions for certain benefit accruals—(1) Attribution of benefits to first disaggregation population. If employees benefiting under a plan change from one disaggregation population to a second disaggregation population, benefits they accrue while members of the second disaggregation population that are attributable to years of service previously credited while the employees were members of the first disaggregation population may be treated as provided to them in their status as members of the first disaggregation population and thus included in the portion of the plan benefiting employees of the first disaggregation population. This special treatment is available only if it is applied on a consistent basis, if it does not result in significant discrimination in favor of highly compensated employees, and if the plan provision providing the additional benefits applies on the same terms to all similarly-situated employees. For example, if all formerly collectively bargained employees accrue additional benefits under a plan after becoming noncollectively bargained employees, then those benefit increases may be treated as included in the portion of the plan benefiting collectively bargained employees if they are attributable to years of service credited while the employees were collectively bargained (e.g., where the additional benefits result from compensation increases that occur while the employees are noncollectively bargained or from plan amendments affecting benefits earned while collectively bargained that are adopted while the employees are noncollectively bargained) and if such treatment does not result in significant discrimination in favor of highly compensated employees.

(2) Attribution of benefits to current disaggregation population. If employees benefiting under a plan change from one disaggregation population to another disaggregation population, benefits they accrue while members of the first disaggregation population may be treated as provided to them in their current status and thus included in the portion of the plan benefiting employees of the disaggregation population of which they are currently members. This special treatment is available only if it is applied on a consistent basis and if it does not result in significant discrimination in favor of highly compensated employees.

(D) Change in disaggregation populations—(1) Reasonable treatment. If, in previous years, the configuration of a plan's disaggregation populations differed from their configuration for the current year, for purposes of the benefits accrued by, or allocations made to, an employee for those years, the employee's status as a member of a current disaggregation population for those years must be determined on a reasonable basis. A different configuration occurs, for example, if disaggregation populations exist for the first time, such as when an employer is first treated as operating qualified separate lines of business, or if the existing disaggregation populations change, such as when an employer redesignates its qualified separate lines of business.

(2) Example. The following example illustrates the application of this paragraph (c)(4)(i)(D).

(ii) Definition of disaggregation population—(A) Plan benefiting employees of qualified separate lines of business. If an employer is treated as operating qualified separate lines of business for purposes of section 410(b) in accordance with § 1.414(r)-1(b), and a plan benefits employees of more than one qualified separate line of business, the employees of each qualified separate line of business are separate disaggregation populations. In this case, the portion of the plan benefiting the employees of each qualified separate line of business is treated as a separate plan maintained by that qualified separate line of business. However, employees of different qualified separate lines of business who are benefiting under a plan that is tested under the special rule for employer-wide plans in § 1.414(r)-1(c)(2)(ii) for a plan year are not separate disaggregation populations merely because they are employees of different qualified separate lines of business.

(B) Plan benefiting collectively bargained employees. If a plan benefits both collectively bargained employees and noncollectively bargained employees, the collectively bargained employees are one disaggregation population and the noncollectively bargained employees are another disaggregation population. If the population of collectively bargained employees includes employees covered under different collective bargaining agreements, the population of employees covered under each collective bargaining agreement is also a separate disaggregation population.

(C) Plan maintained by more than one employer. If a plan benefits employees of more than one employer, the employees of each employer are separate disaggregation populations. In this case, the portion of the plan benefiting the employees of each employer is treated as a separate plan maintained by that employer, which must satisfy section 410(b) by reference only to that employer's employees. However, for purposes of this paragraph (c)(4)(ii)(C), if the plan of one employer (or, in the case of a plan maintained by more than one employer, the plan provisions applicable to the employees of one employer) treats compensation or service with another employer as compensation or service with the first employer, then the current accruals attributable to that compensation or service are treated as provided to an employee of the first employer under the plan of the first employer (or the portion of a plan maintained by more than one employer benefiting employees of the first employer), and the provisions of paragraph (c)(4)(i)(C) of this section do not apply to those accruals. Thus, for example, if Plan A maintained by Employer X imputes service or compensation for an employee of Employer Y, then Plan A is not treated as benefiting the employees of more than one employer merely because of this imputation.

(5) Additional rule for plans benefiting employees of more than one qualified separate line of business. If a plan benefiting employees of more than one qualified separate line of business satisfies the reasonable classification requirement of § 1.410(b)-4(b) before the application of paragraph (c)(4) of this section, then any portion of the plan that is treated as a separate plan as a result of the application of paragraphs (c)(4)(i)(A) and (ii)(A) of this section is deemed to satisfy that requirement.

(d) Permissive aggregation for ratio percentage and nondiscriminatory classification tests—(1) In general. Except as provided in paragraphs (d)(2) and (d)(3) of this section, for purposes of applying the ratio percentage test of § 1.410(b)-2(b)(2) or the nondiscriminatory classification test of § 1.410(b)-4, an employer may designate two or more separate plans (determined after application of paragraph (b) of this section) as a single plan. If an employer treats two or more separate plans as a single plan under this paragraph, the plans must be treated as a single plan for all purposes under sections 401(a)(4) and 410(b).

(2) Rules of disaggregation. An employer may not aggregate portions of a plan that are disaggregated under the rules of paragraph (c) of this section. Similarly, an employer may not aggregate two or more separate plans that would be disaggregated under the rules of paragraph (c) of this section if they were portions of the same plan. In addition, an employer may not aggregate an ESOP with another ESOP, except as permitted under § 54.4975-11(e) of this Chapter.

(3) Duplicative aggregation. A plan may not be combined with two or more plans to form more than one single plan. Thus, for example, an employer that maintains plans A, B, and C may not aggregate plans A and B and plans A and C to form two single plans. However, the employer may apply the permissive aggregation rules of this paragraph (d) to form any one (and only one) of the following combinations: plan ABC, plans AB and C, plans AC and B, or plans A and BC.

(4) Special rule for plans benefiting employees of a qualified separate line of business. For purposes of paragraph (d)(1) of this section, an employer that is treated as operating qualified separate lines of business for purposes of section 410(b) in accordance with § 1.414(r)-1(b) is permitted to aggregate the portions of two or more plans that benefit employees of the same qualified separate line of business (regardless of whether the employer elects to aggregate the portions of the same plans that benefit employees of the other qualified separate lines of business of the employer), provided that none of the plans is tested under the special rule for employer-wide plans in § 1.414(r)-1 (c)(2)(ii). Thus, the employer is permitted to apply paragraph (d)(1) of this section with respect to two or more separate plans determined after the application of paragraphs (b) and (c)(4) of this section, but may not aggregate a plan that is tested under the special rule for employer-wide plans in § 1.414(r)-1(c)(2)(ii) for a plan year with any portion of a plan that does not rely on that special rule for the plan year. In all other respects, the provisions of this paragraph (d) regarding permissive aggregation apply, including (but not limited to) the disaggregation rules under paragraph (d)(2) of this section (including the mandatory disaggregation rule of paragraph (c)(4) of this section), and the prohibition on duplicative aggregation under paragraph (d)(3) of this section. This paragraph (d)(4) applies only in the case of an employer that is treated as operating qualified separate lines of business for purposes of section 410(b) in accordance with § 1.414(r)-1(b). See §§ l.414(r)-1(c)(2) and 1.414(r)-8 (separate application of section 410(b) to the employees of a qualified separate line of business).

(5) Same plan year requirement. Two or more plans may not be aggregated and treated as a single plan under this paragraph (d) unless they have the same plan year.

(e) Determination of plans in testing group for average benefit percentage test—(1) In general. For purposes of applying the average benefit percentage test of § 1.410(b)-5 with respect to a plan, all plans in the testing group must be taken into account. For this purpose, the plans in the testing group are the plan being tested and all other plans of the employer that could be permissively aggregated with that plan under paragraph (d) of this section. Whether two or more plans could be permissively aggregated under paragraph (d) of this section is determined (i) without regard to the rule in paragraph (d)(4) of this section that portions of two or more plans benefiting employees of the same line of business may not be aggregated if any of the plans is tested under the special rule for employer-wide plans in § 1.414(r)-1(c)(2)(ii), (ii) without regard to paragraph (d)(5) of this section, and (iii) by applying paragraph (d)(2) of this section without regard to paragraphs (c)(1) and (c)(2) of this section.

(2) Examples. The following example illustrates the rules of this paragraph (e).

(f) Section 403(b) plans. In determining whether a plan satisfies section 410(b), a plan subject to section 403(b)(12)(A)(i) is disregarded. However, in determining whether a plan subject to section 403(b)(12)(A)(i) satisfied section 410(b), plans that are not subject to section 403(b)(12)(A)(i) may be taken into account.

(a) Testing methods—(1) In general. A plan must satisfy section 410(b) for a plan year using one of the testing options in paragraphs (a)(2) through (a)(4) of this section. Whichever testing option is used for the plan year must also be used for purposes of applying section 401(a)(4) to the plan for the plan year. The annual testing option in paragraph (a)(4) of this section must be used in applying section 410(b) to a section 401(k) plan or a section 401(m) plan, and in applying the average benefit percentage test of § 1.410(b)-5. For purposes of this paragraph (a), the plan provisions and other relevant facts as of the last day of the plan year regarding which employees benefit under the plan for the plan year are applied to the employees taken into account under the testing option used for the plan year. For this purpose, amendments retroactively correcting a plan in accordance with § 1.401(a)(4)-11(g) are taken into account as plan provisions in effect as of the last day of the plan year.

(2) Daily testing option. A plan satisfies section 410(b) for a plan year if it satisfies § 1.410(b)-2 on each day of the plan year, taking into account only those employees (or former employees) who are employees (or former employees) on that day.

(3) Quarterly testing option. A plan is deemed to satisfy section 410(b) for a plan year if the plan satisfies § 1.410(b)-2 on at least one day in each quarter of the plan year, taking into account for each of those days only those employees (or former employees) who are employees (or former employees) on that day. The preceding sentence does not apply if the plan's eligibility rules or benefit formula operate to cause the four quarterly testing days selected by the employer not to be reasonably representative of the coverage of the plan over the entire plan year.

(4) Annual testing option. A plan satisfies section 410(b) for a plan year if it satisfies § 1.410(b)-2 as of the last day of the plan year, taking into account all employees (or former employees) who were employees (or former employees) on any day during the plan year.

(5) Example. The following example illustrates this paragraph (a).

(b) Family member aggregation rule. For purposes of section 410(b), and in accordance with section 414(q)(6), a highly compensated employee who is a 5-percent owner or one of the ten most highly compensated employees and any family member (or members) of such a highly compensated employee who is also an employee of the employer are to be treated as a single highly compensated employee. If any member of that group is benefiting under a plan, the deemed single employee is treated as benefiting under the plan. If no member of that group is benefiting under a plan, the deemed single employee is treated as not benefiting under the plan.

In applying this section and §§ 1.410(b)-2 through 1.410(b)-10, the definitions in this section govern unless otherwise provided.

Collectively bargained employee. Collectively bargained employee means a collectively bargained employee within the meaning of § 1.410(b)-6(d)(2).

Defined benefit plan. Defined benefit plan means a defined benefit plan within the meaning of section 414(j). The portion of a plan described in section 414(k) that does not consist of separate accounts is treated as a defined benefit plan.

Defined contribution plan. Defined contribution plan means a defined contribution plan within the meaning of section 414(i). The portion of a plan described in section 414(k) that consists of separate accounts is treated as a defined contribution plan.

Employee. Employee means an individual who performs services for the employer who is either a common law employee of the employer, a self-employed individual who is treated as an employee pursuant to section 401(c)(1), or a leased employee (not excluded under section 414(n)(5)) who is treated as an employee of the employer-recipient under section 414(n)(2) or 414(o)(2). Individuals that an employer treats as employees under section 414(n) pursuant to the requirements of section 414(o) are considered to be leased employees for purposes of this rule. In addition, an individual must be treated as an employee with respect to allocations under a defined contribution plan taken into account under § 1.401(a)(4)-2(c)(ii) and with respect to increases in accrued benefits (within the meaning of 411(a)(7)) under a defined benefit plan that are based on ongoing service or compensation (including imputed service or compensation) credits.

Employer. Employer means the employer maintaining the plan and those employers required to be aggregated with the employer under sections 414(b), (c), (m), or (o). An individual who owns the entire interest of an unincorporated trade or business is treated as an employer. Also, a partnership is treated as the employer of each partner and each employee of the partnership.

ESOP. ESOP or employee stock ownership plan means an employee stock ownership plan within the meaning of section 4975(e)(7) or a tax credit employee stock ownership plan within the meaning of section 409(a).

Former employee. Former employee means an individual who was, but has ceased to be, an employee of the employer (i.e., the individual has ceased performing services as an employee for the employer). An individual is treated as a former employee beginning on the day after the day on which the individual ceases performing services as an employee for the employer. Thus, an individual who ceases performing services as an employee for an employer during a plan year is both an employee and a former employee for the plan year. Notwithstanding the foregoing, an individual is an employee (and not a former employee) to the extent that the individual is treated as an employee with respect to the plan for the plan year under the definition of employee in this section.

Highly compensated employee. Highly compensated employee means an employee who is a highly compensated employee within the meaning of section 414(q) or a former employee treated as an employee under the definition of employee in this section who is a highly compensated former employee within the meaning of section 414(q).

Highly compensated former employee. Highly compensated former employee means a former employee who is a highly compensated former employee within the meaning of section 414(q).

Multiemployer plan. Multiemployer plan means a multiemployer plan within the meaning of section 414(f).

Noncollectively bargained employee. Noncollectively bargained employee means an employee who is not a collectively bargained employee.

Nonhighly compensated employee. Nonhighly compensated employee means an employee who is not a highly compensated employee.

Nonhighly compensated former employee. Nonhighly compensated former employee means a former employee who is not a highly compensated former employee.

Plan year. Plan year means the plan year of the plan as defined in the written plan document. In the absence of a specifically designated plan year, the plan year is deemed to be the calendar year.

Plan year compensation. Plan year compensation means plan year compensation within the meaning of § 1.401(a)(4)-12.

Professional employee. Professional employee means any highly compensated employee who, on any day of the plan year, performs professional services for the employer as an actuary, architect, attorney, chiropodist, chiropractor, dentist, executive, investment banker, medical doctor, optometrist, osteopath, podiatrist, psychologist, certified or other public accountant, stockbroker, or veterinarian, or in any other professional capacity determined by the Commissioner in a notice or other document of general applicability to constitute the performance of services as a professional.

Ratio percentage. With respect to a plan for a plan year, a plan's ratio percentage means the percentage (rounded to the nearest hundredth of a percentage point) determined by dividing the percentage of the nonhighly compensated employees who benefit under the plan by the percentage of the highly compensated employees who benefit under the plan. The percentage of the nonhighly compensated employees who benefit under the plan is determined by dividing the number of nonhighly compensated employees benefiting under the plan by the total number of nonhighly compensated employees of the employer. The percentage of the highly compensated employees who benefit under the plan is determined by dividing the number of highly compensated employees benefiting under the plan by the total number of highly compensated employees of the employer.

Section 401(k) plan. Section 401(k) plan means a plan consisting of elective contributions described in § 1.40(k)-1(g)(3) under a qualified cash or deferred arrangement described in § 1.401(k)-1(a)(4)(i). Thus, a section 401(k) plan does not include a plan (or portion of a plan) that consists of contributions under a nonqualified cash or deferred arrangement, or qualified nonelective or qualified matching contributions treated as elective contributions under § 1.401(k)-1(a)(6).

Section 401( l) plan. Section 401( l) plan means a plan that—

(1) Provides for a disparity in employer-provided benefits or contributions that satisfies section 401(l) in form, and

(2) Relies on one of the safe harbors of § 1.401(a)(4)-2(b)(2), 1.401(a)(4)-3(b), 1.401(a)(4)-8(b)(3), or 1.401(a)(4)-8(c)(3)(iii)(B) to satisfy section 401(a)(4).

Section 401(m) plan. Section 401(m) plan means a plan consisting of employee contributions described in § 1.401(m)-1(f)(6) or matching contributions described in § 1.40(m)-1(f)(12), or both. Thus, a section 401(m) plan does not include a plan (or portion of a plan) that consists of elective contributions or qualified nonelective contributions treated as matching contributions under § 1.401(m)-1(b)(5).

(a) Statutory effective dates—(1) In general. Except as set forth in paragraph (a)(2) of this section, the minimum coverage rules of section 410(b) as amended by section 1112 of the Tax Reform Act of 1986 apply to plan years beginning on or after January 1, 1989.

(2) Special statutory effective date for collective bargaining agreements—(i) In general. As provided for by section 1112(e)(2) of the Tax Reform Act of 1986, in the case of a plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified before March 1, 1986, the minimum coverage rules of section 410(b) as amended by section 1112 of the Tax Reform Act of 1986 do not apply to employees covered by any such agreement in plan years beginning before the earlier of—

(A) January 1, 1991; or

(B) The later of January 1, 1989, or the date on which the last of such collective bargaining agreements terminates (determined without regard to any extension thereof after February 28, 1986). For purposes of this paragraph (a)(2), any extension or renegotiation of a collective bargaining agreement, which extension or renegotiation is ratified after February 28, 1986, is to be disregarded in determining the date on which the agreement terminates.

(ii) Example. The following example illustrates this paragraph (a)(2).

(iii) Plan maintained pursuant to a collective bargaining agreement. For purposes of this paragraph (a)(2), a plan is maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers, if one or more of the agreements were ratified before March 1, 1986. Only plans maintained pursuant to agreements that the Secretary of Labor finds to be collective bargaining agreements and that satisfy section 7701(a)(46) are eligible for the deferred effective date under this paragraph (a)(2). A plan will not be treated as a plan maintained pursuant to one or more collective bargaining agreements eligible for the deferred effective date under this paragraph (a)(2) unless the plan would be a plan maintained pursuant to one or more collective bargaining agreements under the principles applied under section 1017(c) of the Employee Retirement Income Security Act of 1974. See H.R. Rep. No. 1280, 93rd Cong. 2d Sess. 266 (1974).

(b) Regulatory effective dates—(1) In general. Except as otherwise provided in this section, §§ 1.410(b)-2 through 1.410(b)-9 apply to plan years beginning on or after January 1, 1994.

(2) Plans of tax-exempt organizations. In the case of plans maintained by organizations exempt from income taxation under section 501(a), including plans subject to section 403(b)(12)(A)(i) (nonelective plans), §§ 1.410(b)-2 through 1.410(b)-9 apply to plan years beginning on or after January 1, 1996, to the extent such plans are subject to section 410(b).

(c) Compliance during transition period. For plan years beginning before the effective date of these regulations, as set forth in paragraph (b) of this section, and on or after the statutory effective date as set forth in paragraph (a) of this section, a plan must be operated in accordance with a reasonable, good faith interpretation of section 410(b). Whether a plan is operated in accordance with a reasonable, good faith interpretation of section 410(b) will generally be determined based on all of the relevant facts and circumstances, including the extent to which an employer has resolved unclear issues in its favor. If a plan's classification has been determined by the Commissioner to be nondiscriminatory and there have been no significant changes in or omissions of a material fact, the classification will be treated as nondiscriminatory for the relevant plan year. A plan will be deemed to be operated in accordance with a reasonable, good faith interpretation of section 410(b) if it is operated in accordance with the terms of §§ 1.410(b)-2 through 1.410(b)-9.

(d) Effective date for governmental plans. In the case of governmental plans described in section 414(d), including plans subject to section 403(b)(12)(A)(i) (nonelective plans) § 1.410(b)-2 through § 1.410(b)-10 apply to plan years beginning on or after January 1, 1996, or 90 days after the opening of the first legislative session beginning on or after January 1, 1996, of the governing body with authority to amend the plan, if that body does not meet continuously. Such plans are deemed to satisfy section 410(b) (and in the case of such plans that are not subject to section 403(b)(12)(A)(i), section 401(a)(3) as in effect on September 1, 1974) for plan years before that effective date. For purposes of this section, the governing body with authority to amend the plan is the legislature, board, commission, council, or other governing body with authority to amend the plan. See § 1.410(b)-2(d) and (e).

(e) Effective date for provisions relating to exclusion of employees of certain tax-exempt entities. The provisions in § 1.410(b)-6(g) apply to plan years beginning after December 31, 1996. For plan years to which § 1.410(b)-6 applies that begin before January 1, 1997, § 1.410(b)-6(g) (as it appeared in the April 1, 2005 edition of 26 CFR part 1) applies.

(a) In general. If a church or convention or association of churches which maintains any church plan, as defined in section 414(e), makes an election under this section, certain provisions of the Code and title I of the Employee Retirement Income Security Act of 1974 (the “Act”) shall apply to such church plan as if such plan were not a church plan. The provisions of the Code referred to are section 410 (relating to minimum participation standards), section 411 (relating to minimum vesting standards), section 412 (relating to minimum funding standards), section 4975 (relating to prohibited transactions), and paragraphs (11), (12), (13), (14), (15), and (19) of section 401(a) (relating to joint and survivor annuities, mergers and consolidations, assignment or alienation of benefits, time of benefit commencement, certain social security increases, and withdrawals of employee contributions, respectively).

(b) Election is irrevocable. An election under this section with respect to any church plan shall be binding with respect to such plan and, once made, shall be irrevocable.

(c) Procedure for making election—(1) Time of election. An election under this section may be made for plan years for which the provisions of section 410(d) of the Code apply to the church plan. By reason of section 1017(b) of the Act section 410(d) does not apply to a plan in existence on January 1, 1974, for plan years beginning before January 1, 1976. Section 1017(d) of the Act permits a plan administrator to elect to have certain provisions of the Code (including section 410(d)) apply to a plan before the otherwise applicable effective dates of such provisions. See § 1.410(a)-2(d). Therefore, for a plan in existence on Janurary 1, 1974, an election under section 410(d) of the Code may be made for a plan year beginning before January 1, 1976, only if an election has been made under section 1017(d) of the Act with respect to that plan year.

(2) By whom election is to be made. The election provided by this section may be made only by the plan administrator of the church plan.

(3) Manner of making election. The plan administrator may elect to have the provisions of the Code described in paragraph (a) of this section apply to the church plan as it is were not a church plan by attaching the statement described in subparagraph (5) of this paragraph to either (i) the annual return required under section 6058(a) (or an amended return) with respect to the plan which is filed for the first plan year for which the election is effective or (ii) a written request for a determination letter relating to the qualification of the plan under section 401(a), 403(a), or 405(a) of the Code and if trusteed, the exempt status under section 501(a) of the Code of a trust constituting a part of the plan.

(4) Conditional election. If an election is made with a written request for a determination letter, the election may be conditioned upon issuance of a favorable determination letter and will become irrevocable upon issuance of such letter.

(5) Statement. The statement described in subparagraph (3) of this paragraph shall indicate (i) that the election is made under section 410(d) of the Code and (ii) the first plan year for which it is effective.

(a) In general. A plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) unless—

(1) The plan provides that an employee's right to his normal retirement benefit (see § 1.411(a)-7(c)) is nonforfeitable (see § 1.411(a)-4) upon and after the attainment of normal retirement age (see § 1.411(a)-7(b)),

(2) The plan provides that an employee's rights in his accrued benefit derived from his own contributions (see § 1.411(c)-1) are nonforfeitable at all times, and

(3) The plan satisfies the requirements of—

(A) Section 411(a)(2) and § 1.411(a)-3 (relating to vesting in accrued benefit derived from employer contributions), and

(B) In the case of a defined benefit plan, section 411(b)(1) and § 1.411(b)-1 (relating to accrued benefit).

(b) Organization of regulations relating to minimum vesting standards—(1) General rules. This section prescribes general rules relating to the minimum vesting standards provided by section 411.

(2) Effective dates. Section 1.411(a)-2 provides rules under section 1017 of the Employee Retirement Income Security Act of 1974 relating to effective dates under section 411.

(3) Employer contributions. Section 1.411(a)-3 provides rules under section 411(a)(2) relating to vesting in employer-derived accrued benefits.

(4) Certain forfeitures. Section 1.411(a)-4 provides rules under section 411(a)(3) relating to certain permitted forfeitures, suspensions, etc. under qualified plans.

(5) Nonforfeitable percentage. Section 1.411(a)-5 provides rules under section 411(a)(4) relating to service included in the determination of an employee's nonforfeitable percentage under section 411(a)(2) and § 1.411(a)-3.

(6) Years of service; break in service. Section 1.411(a)-6 provides rules under section 411(a) (5) and (6) of the Internal Revenue Code of 1954 relating to years of service and breaks in service. Rules prescribed by the Secretary of Labor, relating to years of service and breaks in service under part 2 of subtitle B of title I of the Employee Retirement Income Security Act of 1974 are provided under 29 CFR Part 2530 (Department of Labor regulations relating to minimum standards for employee pension benefit plans).

(7) Definitions and special rules. Section 1.411(a)-7 provides definitions and special rules under section 411(a) (7), (8), and (9), for purposes of section 411 and the regulations thereunder.

(8) Changes in vesting schedule. Section 1.411(a)-8 provides rules under section 411(a)(10) relating to changes in the vesting schedule of a plan.

(9) [Reserved]

(10) Accrued benefits. See § 1.411(b)-1 for rules under section 411(b) relating to accrued benefit requirements under defined benefit plans.

(11) Allocation of accrued benefits. See § 1.411(c)-1 for rules under section 411(c) relating to allocation of accrued benefits between employer and employee contributions.

(12) Discrimination, etc. See § 1.411(d)-1 for rules relating to the coordination of section 411 with section 401(a)(4) (relating to discrimination) and other rules under section 411(d).

(c) Application of standards to certain plans—(1) General rule. Except as provided in subparagraph (2) of this paragraph, section 411 does not apply to—

(i) A governmental plan (within the meaning of section 414(d) and the regulations thereunder),

(ii) A church plan (within the meaning of section 414(e) and the regulations thereunder) which has not made the election provided by section 410(d) and the regulations thereunder,

(iii) A plan which has not provided for employer contributions at any time after September 2, 1974, and

(iv) A plan established and maintained by a society, order, or association described in section 501(c) (8) or (9), if no part of the contributions to or under such plan are made by employers of participants in such plan.

(2) Vesting requirements. A plan described in subparagraph (1) of this paragraph shall, for purposes of section 401(a), be treated as meeting the requirements of section 411 if such plan meets the vesting requirements resulting from the application of section 401(a)(4) and section 401(a)(7) as in effect on September 1, 1974.

(d) Supersession. Sections 11.411(a)-1 through 11.411(d)-3, inclusive, of the Temporary Income Tax Regulations under the Employee Retirement Income Security Act of 1974 are superseded by this section and §§ 1.411(a)-2 through 1.411(d)-3.

(a) Plan not in existence on January 1, 1974. Under section 1017(a) of the Employee Retirement Income Security Act of 1974, in the case of a plan which was not in existence on January 1, 1974, section 411 and the regulations thereunder apply for plan years beginning after September 2, 1974. See paragraph (c) of this section for time plan is considered in existence.

(b) Plans in existence on January 1, 1974. Under section 1017(b) of the Employee Retirement Income Security Act of 1974, in the case of a plan which was in existence on January 1, 1974, section 411 and the regulations thereunder apply for plan years beginning after December 31, 1975. See paragraph (c) of this section for time plan is considered to be in existence.

(c) Time of plan existence—(1) General rule. For purposes of this section, a plan is considered to be in existence on a particular day if—

(i) The plan on or before that day was reduced to writing and adopted by the employer (including, in the case of a corporate employer, formal approval by the employer's board of directors and, if required, shareholders), even though no amounts had been contributed under the plan as of such day, and

(ii) The plan was not terminated on or before that day.

(2) Collectively-bargained plan. Notwithstanding paragraph (c) (1) of this section, a plan described in section 413 (a), relating to a plan maintained pursuant to a collective-bargaining agreement, is considered to be in existence on a particular day if—

(i) On or before that day there is a legally enforceable agreement to establish such a plan signed by the employer, and

(ii) The employer contributions to be made to the plan are set forth in the agreement.

(3) Special rule. If a plan is considered to be in existence under subparagraph (1) of this paragraph, any other plan with which such existing plan is merged or consolidated shall also be considered to be in existence on such date.

(d) Existing plans under collective-bargaining agreements. For a special effective date rule for certain plans maintained pursuant to a collective bargaining agreement, see section 1017(c)(1) of the Employee Retirement Income Security Act of 1974 (88 Stat. 932).

(e) Certain existing plans may elect new provisions. The plan administrator may elect to have the provisions of the Code relating to participation, vesting, funding, and form of benefit apply to a selected plan year. See § 1.410(a)-2(d) for rules relating to such an election.

(f) Application of rules. The requirements of section 411 do not apply to employees who separate from service with the employer prior to the first plan year to which such requirements apply and who never return to service with the employer in a plan year to which section 411 applies.

(a) In general—(1) Alternative requirements. A plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) unless the plan satisfies the requirements of section 411(a)(2) and this section. A plan satisfies the requirements of this section if is satisfies the requirements of paragraph (b), (c), or (d) of this section.

(2) Composite arrangements. A plan will not be considered to satisfy the requirements of paragraph (b), (c), or (d) of this section unless it satisfies all requirements of a particular one of such paragraphs with respect to all of an employee's years of service. A plan which, for example, satisfies the requirements of paragraph (b) (but not (c) or (d)) for an employee's first 9 years of service and satisfies the requirements of paragraph (c) (but not (b)) for all of his remaining years of service, does not satisfy the requirements of this section. A plan is not precluded from satisfying the requirement of one such paragraph with respect to one group of employees and another such paragraph with respect to another group provided that the groups are not so structured as to evade the requirements of this paragraph. For example, if plan A provides that employees who commence participation before age 30 are subject to the “rule of 45” vesting schedule and employees who commence participation after age 30 are subject to the full vesting after 10 years schedule, plan A would be so structured as to evade the requirements of this paragraph.

(3) Plan amendments. A plan which satisfies the requirements of a particular one of such paragraphs for each of an employee's years of service and which is amended so that, as amended, it satisfies the requirements of another such paragraph for all such years of service, satisfies the requirements of this section even though, as amended, it does not satisfy the requirements of the paragraph which were satisfied prior to the amendment. See § 1.411(a)-8 for rules relating to employee election where the vesting schedule is amended.

(b) 10-year vesting. A plan satisfies the requirements of section 411(a)(2) (A) and this paragraph if an employee who has completed 10 years of service has a nonforfeitable right to 100 percent of his accrued benefit derived from employer contributions.

(c) 5- to 15-year vesting. A plan satisfies the requirements of section 411(a)(2) (B) and this paragraph if an employee who has completed at least 5 years of service has a nonforfeitable right to a percentage of his accrued benefit derived from employer contribution which percentage is not less than the nonforfeitable percentage determined under the following table:

(d) Rule of 45. A plan satisfies the requirements of section 411(a)(2)(C) and this paragraph if an employee is entitled to the greater of the two percentages determined under paragraph (d) (1) or (2) of this section.

(1) Age and service test. An employee who is not separated from the service, who has completed at least 5 years of service, and with respect to whom the sum of his age and years of service equals of exceeds 45, has a nonforfeit- able right to a percentage of his accrued benefit derived from employer contributions which is not less than the nonforfeitable percentage corresponding to his number of completed years of service to the sum of his age and completed years of service (whichever percentage is the lesser) determined under the following table:

(2) Service test. An employee who has completed at least 10 years of service has a nonforfeitable right to a percentage of his accrued benefit derived from employer contributions determined under the following table:

(3) Computation of age. For purposes of subparagraph (1) of this paragraph, the age of an employee is his age on his last birthday.

(e) Examples. The rules provided by this section are illustrated by the following examples:

(a) In general—(1) [Reserved]

(2) Composite arrangements. A plan will not be considered to satisfy the requirements of paragraph (b), (c), or (d) of this section unless it satisfies all requirements of a particular one of such paragraphs with respect to all of an employee's years of service. A plan which, for example, satisfies the requirements of paragraph (b) (but not (c) or (d)) for an employee's first 4 years of service and satisfies the requirements of paragraph (c) (but not (b)) for all of his remaining years of service does not satisfy the requirements of this section. A plan is not precluded from satisfying the requirements of one such paragraph with respect to one group of employees and another such paragraph with respect to another group provided that the groups are not so structured as to evade the requirements of this paragraph.

(b) 5-year vesting. A plan satisfies the requirements of section 411(a)(2)(A) and this paragraph if an employee who has completed 5 years of service has a nonforfeitable right to 100 percent of his or her accrued benefits derived from employer contributions.

(c) 3- to 7-year vesting. A plan satisfies the requirements of section 411(a)(2)(B) and this paragraph if an employee who has completed at least 3 years of service has a nonforfeitable right to a percentage of his accrued benefit derived from employer contributions, which percentage is not less than the nonforfeitable percentage determined under the following table:

(d) Multiemployer plans. A plan satisfies the requirements of section 411(a)(2)(C) and this paragraph if—

(1) The plan is a multiemployer plan (within the meaning of section 414(f)), and

(2) Under the plan—

(i) An employee who is covered pursuant to a collective bargaining agreement described in section 414(f)(1)(B) has a nonforfeitable right to 100 percent of the employee's accrued benefit derived from employer contributions not later than upon completion of 10 years of service, and

(ii) The requirements of paragraph (b) or (c) of this section are met with respect to employees who are not covered pursuant to a collective bargaining agreement described in section 414(f)(1)(B).

(iii) For purposes of this provision, an employee is not covered pursuant to a collective bargaining agreement unless the employee is represented by a bona fide employee representative that is a party to the collective bargaining agreement pursuant to which the multiemployer plan is maintained. Thus, for example, an employee of either the multiemployer plan or the employee representative is not covered pursuant to the collective bargaining agreement under which the plan is maintained even if the employee is covered pursuant to an agreement entered into by the multiemployer plan or employee representative on behalf of the employee and even if all such employees covered under the plan constitute only a de minimis percentage of the total employees covered under the plan.

(e) Effective date. (1) The provisions of this section apply to all employees who have one hour of service in any plan year beginning after—

(i) December 31, 1988, or

(ii) In the case of a plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified before March 1, 1986, for employees covered by any such agreement, the earlier of—

(A) The later of—

(1) January 1, 1989, or

(2) The date on which the last of such collective bargaining agreements terminates (determined without regard to any extension thereof after February 28, 1986), or

(B) January 1, 1991.

(2) For employees not described in paragraph (e)(1), above, the regulations in effect prior to January 1, 1989, shall be applied to determine the requirements of this section.

(f) Examples. The rules provided by this section are illustrated by the following examples:

(a) Nonforfeitability. Certain rights in an accrued benefit must be nonforfeitable to satisfy the requirements of section 411(a). This section defines the term “nonforfeitable” for purposes of these requirements. For purposes of section 411 and the regulations thereunder, a right to an accrued benefit is considered to be nonforfeitable at a particular time if, at that time and thereafter, it is an unconditional right. Except as provided by paragraph (b) of this section, a right which, at a particular time, is conditioned under the plan upon a subsequent event, subsequent performance, or subsequent forbearance which will cause the loss of such right is a forfeitable right at that time. Certain adjustments to plan benefits such as adjustments in excess of reasonable actuarial reductions, can result in rights being forfeitable. Rights which are conditioned upon a sufficiency of plan assets in the event of a termination or partial termination are considered to be forfeitable because of such condition. However, a plan does not violate the nonforfeitability requirements merely because in the event of a termination an employee does not have any recourse toward satisfaction of his nonforfeitable benefits from other than the plan assets or the Pension Benefit Guaranty Corporation. Furthermore, nonforfeitable rights are not considered to be forfeitable by reason of the fact that they may be reduced to take into account benefits which are provided under the Social Security Act or under any other Federal or State law and which are taken into account in determining plan benefits. To the extent that rights are not required to be nonforfeitable to satisfy the minimum vesting standards, or the nondiscrimination requirements of section 401(a)(4), they may be forfeited without regard to the limitations on forfeitability required by this section. The right of an employee to repurchase his accrued benefit for example under section 411(a)(3)(D), is an example of a right which is required to satisfy such standards. Accordingly, such a right is subject to the limitations on forfeitability. Rights which are required to be prospectively nonforfeitable under the vesting standards are nonforfeitable and may not be forfeited until it is determined that such rights are, in fact, in excess of the vesting standards. Thus, employees have a right to vest in the accrued benefits if they continue in employment of employers maintaining the plan unless a forfeitable event recognized by section 411 occurs. For example, if a plan covered employees in Division A of Corporation X under a plan utilizing a 10-year 100 percent vesting schedule, the plan could not forfeit employees' rights on account of their moving to service in Division B of Corporation X prior to completion of 10 years of service even though employees are not vested at that time.

(b) Special rules. For purposes of paragraph (a) of this section a right is not treated as forfeitable—

(1) Death—(i) General rule. In the case of a participant's right to his employer-derived accrued benefit, merely because such accrued benefit is forfeitable by the participant to the extent it has not been paid or distributed to him prior to his death. This subparagraph shall not apply to a benefit which must be paid to a survivor in order to satisfy the requirements of section 401(a)(11).

(ii) Employee contributions. A participant's right in his accrued benefit derived from his own contributions must be nonforfeitable at all times. Such a right is not treated as forfeitable merely because, after commencement of annuity or pension payments in a benefit form provided under the plan, the participant dies without receiving payments equal in amount to his nonforfeitable accrued benefit derived from his contributions determined at the time of commencement.

(2) Suspension of benefits upon reemployment of retiree. In the case of certain suspensions of benefits under section 411(a)(3)(B), see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530 (Department of Labor regulations relating to minimum standards for employee pension benefit plans).

(3) Retroactive plan amendment. In the case of a participant's right to his employer-derived accrued benefit, merely because such benefit is subject to reduction to the extent provided by a plan amendment described in section 412(c)(8) and the regulations thereunder, which amendment is given retroactive effect in accordance with such section.

(4) Other forfeiture rules—(i) Withdrawal of mandatory contributions. For rules allowing forfeitures on account of the withdrawal of mandatory contributions, see § 1.411(a)-7(d) (2) and (3).

(ii) Additional requirements. For additional requirements relating to nonforfeitability of benefits in the event of a withdrawal by the employee, see section 401(a)(19) and § 1.401(a)-19.

(5) Multiemployer plan. In the case of a multiemployer plan described in section 414(f), merely because an employee's accrued benefit which results from service with an employer before such employer was required to contribute to the plan is forfeitable on account of the cessation of contributions by the employer of the employee. This subparagraph shall not apply to an employee's accrued benefit with respect to an employer which accrued under a plan maintained by that employer prior to the adoption by that employer of the multiemployer plan.

(6) Lost beneficiary; escheat. In the case of a benefit which is payable, merely because the benefit is forfeitable on account of the inability to find the participant or beneficiary to whom payment is due, provided that the plan provides for reinstatement of the benefit if a claim is made by the participant or beneficiary for the forfeited benefit. In addition, a benefit which is lost by reason of escheat under applicable state law is not treated as a forfeiture.

(7) Certain matching contributions. A matching contribution (within the meaning of section 401(m)(4)(A) and § 1.401(m)-1(a)(2)) is not treated as forfeitable even if under the plan it may be forfeited under § 1.401(m)-2(b)(1) because the contribution to which it relates is treated as an excess contribution (within the meaning of §§ 1.401(k)-2(b)(2)(ii) and 1.401(k)-6), excess deferral (within the meaning of § 1.402(g)-1(e)(1)(iii)), excess aggregate contribution (within the meaning of § 1.401(m)-5), or a default elective contribution (within the meaning of § 1.414(w)-1(e)) that is withdrawn in accordance with the requirements of § 1.414(w)-1(c).

(c) Examples. The rules of this section are illustrated by the following examples:

(a) Nonforfeitability. Certain rights in an accrued benefit must be nonforfeitable to satisfy the requirements of section 411(a). This section defines the term “nonforfeitable” for purposes of these requirements. For purposes of section 411 and the regulations thereunder, a right to an accrued benefit is considered to be nonforfeitable at a particular time if, at that time and thereafter, it is an unconditional right. Except as provided by paragraph (b) of this section, a right which, at a particular time, is conditioned under the plan upon a subsequent event, subsequent performance, or subsequent forbearance which will cause the loss of such right is a forfeitable right at that time. Certain adjustments to plan benefits, such as adjustments in excess of reasonable actuarial reductions, can result in rights being forfeitable. Rights which are conditioned upon a sufficiency of plan assets in the event of a termination or partial termination are considered to be forfeitable because of such condition. However, a plan does not violate the nonforfeitability requirements merely because in the event of a termination an employee does not have any recourse toward satisfaction of his nonforfeitable benefits from other than the plan assets, the Pension Benefit Guaranty Corporation, or a trust established and maintained pursuant to sections 4041(c)(3)(B) (ii) or (iii) and section 4049 of ERISA with respect to the plan. Furthermore, nonforfeitable rights are not considered to be forfeitable by reason of the fact that they may be reduced as allowed under sections 401(a)(5) and 401(l). To the extent that rights are not required to be nonforfeitable to satisfy the minimum vesting standards, or the nondiscrimination requirements of section 401(a)(4), they may be forfeited without regard to the limitations on forfeitability required by this section. The right of an employee to repurchase his accrued benefit for example under section 411(a)(3)(D), is an example of a right which is required to satisfy such standards. Accordingly, such a right is subject to the limitations on forfeitability. Rights which are required to be prospectively nonforfeitable under the vesting standards are nonforfeitable and may not be forfeited until it is determined that such rights are, in fact, in excess of the vesting standards. Thus, employees have a right to vest in the accrued benefits if they continue in employment of employers maintaining the plan unless a forfeitable event recognized by section 411 occurs. For example, if a plan covered employees in Division A of Corporation X under a plan utilizing a 5-year 100 percent vesting schedule, the plan could not forfeit employees' rights on account of their moving to service in Division B of Corporation X prior to completion of 5 years of service even though employees are not vested at that time.

(b) [Reserved]

(c) Examples. The rules of this section ae illustrated by the following examples:

(a) In general. Under section 411(a)(4), for purposes of determining the nonforfeitable percentage of an employee's right to his employer-derived accrued benefit under section 411(a)(2) and § 1.411(a)-3, all of an employee's years of service with an employer or employers maintaining the plan shall be taken into account except that years of service described in paragraph (b) of this section may be disregarded.

(b) Certain service. For purposes of paragraph (a) of this section, the following years of service may be disregarded:

(1) Service before age 22. (i) In the case of a plan which satisfies the requirements of section 411(a)(2) (A) or (B) (relating to 10-year vesting and 5-15-year vesting, respectively), a year of service completed by an employee before he attains age 22.

(ii) In the case of a plan which does not satisfy the requirements of section 411(a)(2) (A) or (B), a year of service completed by an employee before he attains age 22 if the employee is not a participant (for purposes of section 410) in the plan at any time during such year.

(iii) For purposes of this subparagraph in the case of a plan utilizing computation periods, service during a computation period described in section 411(a)(5)(A) within which the employee attains age 22 may not be disregarded. In the case of a plan utilizing the elapsed time method described in § 1.410(a)-7, service on or after the date on which the employee attains age 22 may not be disregarded.

(2) Contributory plans. In the case of a plan utilizing computation periods, a year of service completed by an employee under a plan which requires mandatory contributions (within the meaning of section 411(c)(2)(C) and § 1.411(c)-1(c)(4)) to be made by the employee for such year, if the employee does not participate for such year solely because of his failure to make all mandatory contributions to the plan for such year. If the employee contributes any part of the mandatory contributions for the year, such year may not be excluded by reason of this subparagraph. In the case of a plan utilizing the elapsed time method described in § 1.410(a)-7, the service which may be disregarded is the period with respect to which the mandatory contribution is not made.

(3) Plan not maintained—(i) In general. An employee's years of service with an employer during any period for which the employer did not maintain the plan or a predecessor plan may be disregarded for purposes of section 411(a)(2). Paragraph (b)(3)(ii) of this section provides rules regarding the period prior to the adoption of a plan. Paragraph (b)(3)(iii) of this section provides rules regarding the period after the termination of a plan. Paragraph (b)(3)(iv) of this section provides rules regarding employers who have certain relationships with other employers maintaining the plan.

(ii) Period prior to adoption. The period for which a plan is not maintained by an employer includes the period before the plan was established. For purposes of this subdivision, a plan is established on the first day of the plan year in which the plan is adopted even though the plan is adopted after such first day. Except as provided in paragraph (b)(3)(iv) of this section if an employer adopts a plan which has previously been established by another employer or group of employers, the plan is not maintained by the adopting employer prior to the first day of the plan year in which the plan is adopted by the adopting employer. In the case of a transfer of assets or liabilities (including a merger or consolidation) involving two plans maintained by a single employer, the successor (or transferee) plan is treated as if it was established at the same time as the date of the establishment of the earliest component plan. In the case of a plan merger, consolidation, or transfer of plan assets or liabilities involving plans of two or more employers, the successor plan is treated as if it were established on each of the separate dates on which such component plan was established for the employees of each employer. Thus, for example, if employer A establishes a plan January 1, 1970, and employer B establishes a plan January 1, 1980, and the plans were subsequently merged, then the merged plan would be treated as if it were in existence on January 1, 1970, with respect to A's employees and as if it were in existence on January 1, 1980, with respect to B's employees.

(iii) Period after termination or withdrawal. The period for which a plan is not maintained by an employer includes the period after the plan is terminated. For purposes of this section, a plan is terminated at the date there is a termination of the plan within the meaning of section 411(d)(3)(A) and the regulations thereunder. Notwithstanding the preceding sentence, if contributions to or under a plan are made after termination, the plan is treated as being maintained until such contributions cease, whether or not accruals are made after such termination. If, after termination of a plan in circumstances under which the employer may be liable to the Pension Benefit Guaranty Corporation under section 4062 of the Act, employer contributions are made to or under the plan to fund benefits accrued at the time of termination, such contributions shall, for purposes of this paragraph, be deemed to be payments in satisfaction of employer liability to such Corporation rather than contributions to or under the plan. In the case of a plan maintained by more than one employer, the period for which the plan is not maintained by the withdrawing employer includes the period after the withdrawal from the plan.

(iv) Certain employers. For purposes of this subparagraph—

(A) Predecessor employers. Service with a predecessor employer who maintained the plan of the current employer is treated as service with such current employer (see section 414(a)(1) and the regulations thereunder), and certain service with a predecessor employer who did not maintain the plan of the current employer is treated as service with the current employer (see section 414(a)(2) and the regulations thereunder).

(B) Related employers. Service with an employer is treated as service for certain related employers for the period during which the employers are related. These related employers include members of a controlled group of corporations (within the meaning of section 1563(a), determined without regard to subsections (a)(4) and (e)(3) (C) thereof) and trades or businesses (whether or not incorporated) which are under common control (see section 414 (b) and (c) and 29 CFR Part 2530, Department of Labor regulations relating to minimum standards for employee pension benefits plans).

(C) Plan maintained by more than one employer. Service with an employer who maintains a plan is treated as service for each other employer who maintains that plan for the period during which the employers are maintaining the plan (see section 413 (b)(4) and (c)(3) and 29 CFR Part 2530, Department of Labor regulations relating to minimum standards for employee pension benefit plans).

(v) Predecessor plan—(A) General rule. In the case of an employee who was covered by a predecessor plan, the time the successor of such plan is maintained for such employee includes the time the predecessor plan was maintained if, as of the later of the time the predecessor plan is terminated or the successor plan is established, the employee's years of service under the predecessor plan are not equalled or exceeded by the aggregate number of consecutive 1-year breaks in service occuring after such years of service. Years of service and breaks in service, without regard to whether the employee has nonforfeitable rights under the predecessor plan, are determined under section 411(a) (5) and (6) except that years between the termination date of the predecessor plan and the date of establishment of the successor plan do not count as years of service.

(B) Definition of predecessor plan. For purposes of this section, if—

(1) An employer establishes a retirement plan (within the meaning of section 7476(d)) qualified under subchapter D of chapter 1 of the Code within the 5-year period immediately preceding or following the date another such plan terminates, and

(2) The other plan is terminated during a plan year to which this section applies.

(C) Example. The rules provided by this subparagraph are illustrated by the following example:

(4) Break in service. A year of service which is not required to be taken into account by reason of a break in service (within the meaning of section 411(a)(6) and § 1.411(a)-6)).

(5) Service before January 1, 1971. A year of service completed by an employee prior to January 1, 1971, unless the employee completes at least 3 years of service at any time after December 31, 1970. For purposes of determining if an employee completes 3 years of service, whether or not consecutive, the exceptions of section 411(a)(4) are not applicable. For the meaning of the term “year of service”, see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(6) Service before effective date. A year of service completed before the first plan year for which this section applies to the plan, if such service would have been disregarded under the plan rules relating to breaks in service (whether or not such rules are so designated in the plan) as such rules were in effect from time to time under the plan. For this purpose, plan rules which result in the loss of prior vesting or benefit accruals of an employee, or which deny an employee eligibility to participate, by reason of separation or failure to complete a required period of service within a specified priod of time (e.g., 300 hours in one year) will be considered break in service rules.

(i) [Reserved]

(ii) Examples. The rules of this subparagraph are illustrated by the following examples:

(c) Special continuity rule for certain plans. For special rules for computing years of service in the case of a plan maintained by more than one employer, see 29 CFR Part 2530 (Department of Labor regulations relating to minimum standards for employee pension benefit plans).

(a) Year of service. Under section 411 (a)(5)(A), for purposes of the regulations thereunder, the term “year of service” is defined in regulations prescribed by the Secretary of Labor under section 203(b)(2)(A) of the Employee Retirement Income Security Act of 1974. For special rules applicable to seasonal industries and maritime industries, see regulations prescribed by the Secretary of Labor under subparagraphs (C) and (D) of section 203(b)(2) of the Employee Retirement Income Security Act of 1974.

(b) Hours of service. Under section 411(a)(5)(B), for purposes of the regulations thereunder, the term “hours of service” has the meaning provided by section 410(a)(3)(C). See regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(c) Breaks in service. Under section 411(a)(6), for purposes of § 1.411(a)-5(b)(4) and of this paragraph—

(1) In general—(i) Year of service after 1-year break in service. In the case of any employee who has incurred a 1-year break in service, years of service completed before such break are not required to be taken into account until the employee has completed one year of service after his return to service.

(ii) Defined contribution plan. In the case of a participant in a defined contribution plan or in an insured defined benefit plan (which plan satisfies the requirements of section 411 (b)(1)(F) and § 1.411(b)-1) who has incurred a 1-year break in service, years of service completed after such break are not required to be taken into account for purposes of determining the nonforfeitable percentage of the participant's right to employer-derived benefits which accrued before such break. This subdivision does not permit years of service completed before a 1-year break in service to be disregarded in determining the nonforfeitable percentage of a participant's right to employer-derived benefits which accrue after such break.

(iii) Nonvested participants. In the case of an employee who is a nonvested participant in employer-derived benefits at the time he incurs a 1-year break in service, years of service completed by such participant before such break are not required to be taken into account for purposes of determining the nonforfeitable percentage of his right to employer-derived benefits if at such time the number of consecutive 1-year breaks in service included in his most recent break in service equals or exceeds the aggregate number of his years of service, whether or not consecutive, completed before such break. In the case of a plan utilizing the elapsed time method described in § 1.410(a)-7, the condition in the preceding sentence shall be satisfied if the period of severance is at least one year and the consecutive period of severance equals or exceeds his prior period of service, whether or not consecutive, completed before such period of severance. In computing the aggregate number of years of service prior to such break, years of service which could have been disregarded under this subdivision by reason of any prior break in service may be disregarded.

(2) One-year break in service defined. The term “1-year break in service” means a calendar year, plan year, or other 12-consecutive month period designated by a plan (and not prohibited under regulations prescribed by the Secretary of Labor) during which the participant has not completed more than 500 hours of service. In the case of a plan utilizing the elapsed time method, the term “1-year break in service” means a 12-consecutive month period beginning on the severance from service date or any anniversary thereof and ending on the next succeeding anniversary of such date; provided, however, that the employee during such 12-consecutive-month period does not complete any hours of service within the meaning of 29 CFR Part 2530.200b-2(a) for the employer or employers maintaining the plan. See regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(d) Examples. The rules provided by this section are illustrated by the following examples:

(a) Accrued benefit. For purposes of section 411 and the regulations thereunder, the term “accrued benefit” means—

(1) Defined benefit plan. In the case of a defined benefit plan—

(i) If the plan provides an accrued benefit in the form of an annual benefit commencing at normal retirement age, such accrued benefit, or

(ii) If the plan does not provide an accured benefit in the form described in subdivision (i) of this subparagraph, an annual benefit commencing at normal retirement age which is the actuarial equivalent (determined under section 411(c)(3) and § 1.411(c)-(5) of the accrued benefit determined under the plan. In general, the term “accrued benefits” refers only to pension or retirement benefits. Consequently, accrued benefits do not include ancillary benefits not directly related to retirement benefits such as payment of medical expenses (or insurance premiums for such expenses), disability benefits not in excess of the qualified disability benefit (see section 411(a)(9) and paragraph (c)(3) of this section), life insurance benefits payable as a lump sum, incidental death benefits, current life insurance protection, or medical benefits described in section 401(h). For purposes of this paragraph a subsidized early retirement benefit which is provided by a plan is not taken into account, except to the extent of determining the normal retirement benefit under the plan (see section 411(a)(9) and paragraph (c) of this section). The accrued benefit includes any optional settlement at normal retirement age under actuarial assumptions no less favorable than those which would be applied if the employee were terminating his employment at normal retirement age. The accrued benefit does not include any subsidized value in a joint and survivor annuity to the extent that the annual benefit of the joint and survivor annuity does not exceed the annual benefit of a single life annuity.

(2) Defined contribution plan. In the case of a defined contribution plan, the balance of the employee's account held under the plan.

(b) Normal retirement age—(1) General rule. For the purposes of section 411 and the regulations thereunder, the term “normal retirement age” means the earlier of—

(i) The time specified by a plan at which a plan participant attains normal retirement age, or

(ii) The later of—

(A) The time the plan participant attains age 65, or

(B) The 10th anniversary of the date the plan participant commences participation in the plan.

(2) Examples. The provisions of this paragraph are illustrated by the following examples:

(c) Normal retirement benefit—(1) In general. For purposes of section 411 and the regulations thereunder, the term “normal retirement benefit” means the periodic benefit under the plan commencing upon early retirement (if any) or at normal retirement age, whichever benefit is greater.

(2) Periodic benefit. For purposes of subparagraph (1) of this paragraph—

(i) In the case of a plan under which a benefit is payable as an annuity in the same form upon early retirement and at normal retirement age, the greater benefit is determined by comparing the amount of such annuity payments.

(ii) In the case of a plan under which an annuity benefit payable upon early retirement is not in the same form as an annuity benefit payable at normal retirement age, the greater benefit is determined by converting the annuity benefit payable upon early retirement age into the same form of annuity benefit as is payable at normal retirement age and by comparing the amount of the converted early retirement benefit payment with the amount of the normal retirement benefit payment.

(iii) In the case of a plan which is integrated with the Social Security Act or any other Federal or State law, the periodic benefit payable upon and after early retirement age is adjusted for any increases in such benefits occurring on or after early retirement age which are taken into account under the plan. See however, section 401(a)(15) and the regulations thereunder.

(3) Benefits included. For purposes of this paragraph, the normal retirement benefit under a plan shall be determined without regard to ancillary benefits not directly related to retirement benefits such as medical benefits or disability benefits not in excess of the qualified disability benefit; see section 411(a)(7) and paragraph (a)(1) of this section. For this purpose, a qualified disability benefit is a disability benefit which is not in excess of the amount of the benefit which would be payable to the participant if he separated from service at normal retirement age.

(4) Early retirement benefit; social security supplement. (i) For purposes of this paragraph, the early retirement benefit under a plan shall be determined without regard to any social security supplement.

(ii) For purposes of this subparagraph, a social security supplement is a benefit for plan participants which—

(A) Commences before the age and terminates before the age when participants are entitled to old-age insurance benefits, unreduced on account of age, under title II of the Social Security Act, as amended (see section 202 (a) and (g) of such Act), and

(B) Does not exceed such old-age insurance benefit.

(5) Special limitation. If a defined benefit plan bases its normal retirement benefits on employee compensation, the compensation must reflect the compensation which would have been paid for a full year of participation within the meaning of section 411(b)(3). If an employee works less than a full year of participation, the compensation used to determine benefits under the plan for such year of participation must be multiplied by the ratio of the number of hours for a complete year of participation to the number of hours worked in such year. A plan whose benefit formula is computed on a computation base which cannot decrease is not required to adjust employee compensation in the manner described in the previous sentence. Thus, for example, if a plan provided a benefit based on an employee's compensation for his highest five consecutive years or a separate benefit for each year of participation based on the employee's compensation for such year the plan would not have to so adjust compensation. However, if a plan provided a benefit based on an employee's compensation for the employee's last five years or the five highest consecutive years out of the last 10 years, the compensation, would have to be so adjusted. For special rules for applying the limitations on proration of a year of participation for benefit accrual, see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(6) Examples. The provisions of this paragraph are illustrated by the following examples:

(d) Rules relating to certain distributions and cash-outs of accrued benefits—(1) In general. This paragraph sets forth vesting rules applicable to certain distributions from qualified plans and their related trusts (other than class year plans). Subparagraphs (2) and (3) set forth the exceptions to nonforfeitability on account of withdrawal of mandatory contributions provided by section 411(a)(3)(D). When a plan utilizes these exceptions with respect to a given participant's accrued benefit, such accrued benefit is not subject to the cash-out rules or vesting rules of subparagraphs (4) or (5), respectively. Section 411 prescribes certain requirements with respect to accrued benefits under a qualified plan. These requirements would generally not be satisfied if the plan disregarded service in computing accrued benefits even though amounts were distributed on account of such service. Subparagraph (4) of this paragraph sets forth rules under section 411(a)(7)(B) which allow a plan to make distributions and compute accrued benefits without regard to the accrued benefit attributable to the distribution. When a defined contribution plan utilizes this exception with respect to an accrued benefit, the plan is not required to satisfy the rules of subparagraph (5) of this paragraph. Subparagraph (5) of this paragraph sets forth a vesting requirement applicable to certain distributions from defined contribution plans. Subparagraph (6) sets forth other rules which pertain to the distribution rules of this paragraph.

(2) Withdrawal of mandatory contribution—(i) General rule. In the case of a participant's right to his employer-derived accrued benefit, a right is not treated as forfeitable merely because all or a portion of such benefit may be forfeited on account of the withdrawal by the participant of any amount attributable to his accrued benefit derived from his mandatory contributions (within the meaning of section 411(c)(2)(C) and § 1.411(c)-1) before he has become a 50 percent vested participant (within the meaning of § 1.401(a)-19(b)(2)). For purposes of determining the vested percentage, the plan may disregard service after the withdrawal. For example, assume that a plan utilizes 1000 hours for computing years of service and that for the computation period employee A had 1000 hours of service. If A was 40 percent vested at the beginning of the period but only had 800 hours at the time of the withdrawal, the plan could treat A as only 40 percent vested because service after the withdrawal can be disregarded. On the other hand, if A had 1000 hours at the time of the withdrawal, he must receive a year of service for the computation period, even though service is not taken into account until the end of such period.

(ii) Plan repayment provision. (A) Subdivision (i) of this subparagraph shall not apply unless, at the time the amount described in such subdivision is withdrawn by the participant, the plan provides the employee with a right to restoration of his employer-derived accrued benefit to the extent forfeited in accordance with such subdivision upon repayment to the plan of the full amount of the withdrawal.

(B) In the case of a defined benefit plan (as defined in section 414(j)) the restoration of the employee's employer-derived accrued benefit may be conditioned upon repayment of interest on the full amount of the distribution. Such interest shall be computed on the amount of the distribution from the date of such distribution to the date of repayment, compounded annually from the date of distribution, at the rate determined under section 411(c)(2)(C) in effect on the date of repayment. A plan may provide for repayment of interest which is less than the amount determined under the preceding sentence.

(C) In the case of both defined benefit plans and defined contribution plans, the plan repayment provision described in this subparagraph may provide that the employee must repay the full amount of the distribution in order to have the forfeited benefit restored. The plan provision may not require that such repayment be made sooner than the time described in paragraph (d)(2)(ii)(D) of this section.

(D)(1) If a distribution is on account of separation from service, the time for repayment may not end before the earlier of—

(i) 5 years after the first day the employee is subsequently employed, or

(ii) The close of the first period of consecutive 1-year breaks in service commencing after the distribution.

(2) In the case of a plan utilizing the elapsed time method, described in § 1.410(a)-7, the minimum time for repayment shall be determined as in paragraph (d)(2)(ii)(D)(1) of this section except as provided in this subdivision. The 5 consecutive 1-year break periods shall be determined by substituting the term “1-year period of severance” for the term “1-year break in service”. Also, the repayment period both commences and closes in a manner determined by the Commissioner that is consistent with the rules in § 1.410(a)-7 and the substitution in section 411(a)(6) (C) and (D) of a 5-year break-in-service rule for the former 1-year break-in-service rule.

(E) A defined benefit plan using the break-in-service rule described in section 410(a)(5)(D) or a defined contribution plan using the break-in-service rule described in section 411(a)(6)(C) for determining employees' accrued benefits is not required to provide for repayment by an employee whose accrued benefit is disregarded by reason of a plan provision using these rules.

(iii) Computation of benefit. In the case of a defined contribution plan, the employer-derived accrued benefit required to be restored by this subparagraph shall not be less than the amount in the account balance of the employee which was forfeited, unadjusted by any subsequent gains or losses.

(iv) Delayed forfeiture. A defined contribution plan may, in lieu of the forfeiture and restoration described in this subparagraph, provide that the forfeiture does not occur until the expiration of the time for repayment described in subdivision (ii) of this subparagraph provided that the conditions of this subparagraph are satisfied.

(3) Withdrawal of mandatory contributions; accruals before September 2, 1974—(i) General rule. In the case of a participant's right to the portion of the employer-derived benefit which accrued prior to September 2, 1974, a right is not treated as forfeitable merely because all or part of such portion may be forfeited on account of the withdrawal by the participant of an amount attributable to his benefit derived from mandatory contributions (within the meaning of section 411(c)(2)(C) and § 1.411(c)-1(c)(4)) made by the participant before September 2, 1974, if the amount so subject to forfeiture is no more than proportional to such amounts withdrawn. This subparagraph shall not apply to any plan to which any mandatory contribution (within the meaning of section 411(c)(2)(C) and § 1.411(c)-1(c)(4)) is made after September 2, 1974.

(ii) Defined contribution plan. In the case of a defined contribution plan, the portion of a participant's employer-derived benefit which accrued prior to September 2, 1974, shall be determined on the basis of a separate accounting between benefits accruing before and after such date. Gains, losses, withdrawals, forfeitures, and other credits or charges must be separately allocated to such benefits. Any allocation made on a reasonable and consistent basis prior to September 1, 1977, shall satisfy the requirements of this subdivision.

(iii) Defined benefit plan. In the case of a defined benefit plan, the portion of a participant's employer-derived benefit which accrued prior to September 2, 1974, shall be determined in a manner consistent with the determination of an accrued benefit under section 411(b)(1)(D) (see § 1.411(b)-1(c)). Any method of determining such accrued benefit which the Commissioner finds to be reasonable shall satisfy the requirements of this subdivision.

(4) Certain cash-outs of accrued benefits—(i) Involuntary cash-outs. For purposes of determining an employee's right to an accrued benefit derived from employer contributions under a plan, the plan may disregard service performed by the employee with respect to which—

(A) The employee receives a distribution of the present value of his entire nonforfeitable benefit at the time of the distribution;

(B) The requirements of section 411(a)(11) are satisfied at the time of the distribution;

(C) The distribution is made due to the termination of the employee's participation in the plan; and

(D) The plan has a repayment provision which satisfies the requirements of paragraph (d)(4)(iv) of this section in effect at the time of the distribution.

(ii) Voluntary cash-outs. For purposes of determining an employee's accrued benefit derived from employer contributions under a plan, the plan may disregard service performed by the employee with respect to which—

(A) The employee receives a distribution of the present value of his nonforfeitable benefit attributable to such service at the time of such distribution,

(B) The employee voluntarily elects to receive such distribution,

(C) The distribution is made on termination of the employee's participation in the plan, and

(D) The plan has a repayment provision in effect at the time of the distribution which satisfies the requirements of subdivision (iv) of this subparagraph.

(iii) Disregard of service. Service of an employee permitted to be disregarded under subdivision (i) or (ii) of the subparagraph is not required to be taken into account in computing the employee's accrued benefit under the plan. In the case of a voluntary distribution described in subdivision (ii) of this subparagraph which is less than the present value of the employee's total nonforfeitable benefit immediately prior to the distribution, the accrued benefit not required to be taken into account is such total accrued benefit multiplied by a fraction, the numerator of which is the amount of the distribution and the denominator of which is the present value of his total nonforfeitable benefit immediately prior to such distribution. For example, A who is 50 percent vested in an account balance of $1,000 receives a voluntary distribution of $250. The accrued benefit which can be disregarded equals $1,000 times $250/$500, or $500. However, such service may not by reason of this paragraph be disregarded for purposes of determining an employee's years of service under sections 410(a)(3) and 411(a)(4).

(iv) Plan repayment provision. (A) A plan repayment provision satisfies the requirements of this subdivision if, under the provision, the accrued benefit of an employee that is disregarded by a plan under this subparagraph is restored upon repayment to the plan by the employee of the full amount of the distribution. An accrued benefit is not restored unless all of the optional forms of benefit and subsidies relating to such benefit are also restored. A plan is not required to provide for repayment of an accrued benefit unless the employee—

(1) Received a distribution that is in a plan year to which section 411 applies (see § 1.411(a)-2), which distribution is less than the amount of his accrued benefit determined under the same optional form of benefit as the distribution was made, and

(2) Resumes employment covered under the plan.

(B) Example. Plan A provides a single sum distribution equal to the present value of the normal form of the accrued benefit payable at normal retirement age which is a single life annuity. Plan A also provides a subsidized joint and survivor annuity and a subsidized early retirement annuity benefit. A participant who is fully vested and receives a single sum distribution equal to the present value of the single life annuity normal retirement benefit is not required to be provided the right under the plan to repay the distribution upon subsequent reemployment even though the participant received a distribution that did not reflect the value of the subsidy in the joint and survivor annuity or the value of the early retirement annuity subsidy. This is true whether or not the participant had satisfied at the time of the distribution all of the conditions necessary to receive the subsidies. However, if a participant does not receive his total accrued benefit in the optional form of benefit under which his benefit was distributed, the plan must provide for repayment. If the employee repays the distribution in accordance with section 411(a)(7), the plan must restore the employee's accrued benefit which would include the right to receive the subsidized joint and survivor annuity and the subsidized early retirement annuity benefit.

(C) A plan may impose the same conditions on repayments for the restoration of employer-derived accrued benefits that are allowed as conditions for restoration of employer-derived accrued benefits upon repayment of mandatory contributions under paragraphs (d)(2)(ii) (B), (C), (D) and (E) of this section.

(v) In the case of a defined contribution plan, the employer-derived accrued benefit required to be restored by this subparagraph shall not be less than the amount in the account balance of the employee, both the amount distributed and the amount forfeited, unadjusted by any subsequent gains or losses. Thus, for example, if an employee received a distribution of $250 when he was 25 percent vested in an account balance of $1,000, upon repayment of $250 the account balance may not be less than $1,000 even if, because of plan losses, the account balance, if not distributed, would have been reduced to $500.

(vi) For purposes of paragraph (d)(4)(i) of this section, a distribution shall be deemed to be made due to the termination of an employee's participation in the plan if it is made no later than the close of the second plan year following the plan year in which such termination occurs, or if such distribution would have been made under the plan by the close of such second plan year but for the fact that the present value of the nonforfeitable accrued benefit then exceeded the cash-out limit in effect under § 1.411(a)-11(c)(3)(ii). For purposes of determining the entire nonforfeitable benefit, the plan may disregard service after the distribution, as illustrated in paragraph (d)(2)(i) of this section.

(vii) Effective date. Paragraphs (d)(4)(i) and (vi) of this section apply to distributions made on or after March 22, 1999. However, an employer is permitted to apply paragraphs (d)(4)(i) and (vi) of this section to plan years beginning on or after August 6, 1997. Otherwise, for distributions prior to March 22, 1999, §§ 1.411(a)-7 and 1.411(a)-7T, in effect prior to October 17, 2000 (as contained in 26 CFR part 1, revised as of April 1, 2000) apply.

(5) Vesting requirement for defined contribution plans—(i) Application. The requirements of this subparagraph apply to a defined contribution plan which makes distributions to employees from their accounts attributable to employer contributions at a time when—

(A) Employees are less than 100 percent vested in such accounts, and

(B) Under the plan, employees can increase their percentage of vesting in such accounts after the distributions.

(ii) Requirements. In order for a plan, to which this subparagraph applies, to satisfy the vesting requirements of section 411, account balances under the plan (with respect to which percentage vesting can increase) must be computed in a manner which satisfies either subdivision (iii) (A) or (B) of this subparagraph.

(iii) Permissible methods. A plan many provide for either of the following methods, but not both, for computing account balances with respect to which percentage vesting can increase and from which distributions are made:

(A)(1) A separate account is established for the employee's interest in the plan as of the time of the distribution, and

(2) At any relevant time the employee's vested portion of the separate account is not less than an amount (“X”) determined by the formula: X = P(AB + (R × D))−(R × D). For purposes of applying the formula: P is the vested percentage at the relevant time; AB is the account balance at the relevant time; D is the amount of the distribution; R is the ratio of the account balance at the relevant time to the account balance after distribution; and the relevant time is the time at which, under the plan, the vested percentage in the account cannot increase.

(B) At any relevant time the employee's vested portion is not less than an amount (“X”) determined by the formula: X = P(AB + D)−D. For purposes of applying the formula, the terms have the same meaning as under subdivision (iii)(A)(2) of this subparagraph.

(C) An application of the methods described in subdivisions (iii) (A) and (B) of this subparagraph is illustrated by the following examples:

(6) Other rules—(i) Distributions on separation or other event. None of the rules of this paragraph preclude distributions to employees upon separation from service or any other event recognized by the plan for commencing distributions. Such a distribution must, of course, satisfy the applicable qualification requirements pertaining to such distributions. For example, a profitsharing plan could pay the vested portion of an account balance to an employee when he separated from service, but in order to satisfy section 411 the plan might not be able to forfeit the nonvested account balance until the employee has a 1-year break in service. Similarly, the fact that a plan cannot disregard an accrued benefit attributable to service for which an employee has received a distribution because the plan does not satisfy the cash-out requirements of subparagraph (4) of this paragraph does not mean that the employee's accrued benefit (computed by taking into account such service) cannot be offset by the accrued benefit attributable to the distribution.

(ii) Joint and survivor requirements. See § 1.401(a)-11(a)(2) (relating to joint and survivor annuities) for special rules applicable to certain distributions described in this paragraph.

(iii) Plan repayments. (A) Under subparagraphs (2) and (4) of this paragraph, a plan may be required to restore accrued benefits in the event of repayment by an employee.

(B) For purposes of applying the limitations of section 415 (c) and (e), in the case of a defined contribution plan, the repayment by the employee and the restoration by the employer shall not be treated as annual additions.

(C) In the case of a defined contribution plan, the permissible sources for restoration of the accrued benefit are: income or gain to the plan, forfeitures, or employer contributions. Notwithstanding the provisions of § 1.401-1(b)(1)(ii), contributions may be made for such an accrued benefit by a profit-sharing plan even though there are no profits. In order for such a plan to be qualified, account balances (accrued benefits) generally must correspond to assets in the plan. Accordingly, there cannot be an unfunded account balance. However, an account balance will not be deemed to be unfunded in the case of a restoration if assets for the restored benefit are provided by the end of the plan year following the plan year in which the repayment occurs.

(a) Requirement of prior schedule. Under section 411(a)(10)(A), for plan years for which section 411 applies, a plan will be treated as not meeting the minimum vesting standards of section 411(a)(2) if the plan does not satisfy the requirements of this paragraph. If the vesting schedule of a plan is amended, then as of the date such amendment is adopted, the plan satisfies the requirements of this paragraph if, under the plan as amended, in the case of an employee who is a participant on—

(1) The date the amendment is adopted, or

(2) The date the amendment is effective, if later.

(b) Election of former schedule—(1) In general. Under section 411 (a)(10)(B), for plan years for which section 411 applies, if the vesting schedule of a plan is amended, the plan will not be treated as meeting the minimum vesting standards of section 411 (a)(2) unless the plan as amended, provides that each participant whose nonforfeitable percentage of his accrued benefit derived from employer contributions is determined under such schedule, and who has completed at least 5 years of service with the employer, may elect, during the election period, to have the nonforfeitable percentage of his accrued benefit derived from employer contributions determined without regard to such amendment. Notwithstanding the preceding sentence, no election need be provided for any participant whose nonforfeitable percentage under the plan, as amended, at any time cannot be less than such percentage determined without regard to such amendment.

(2) Election period. For purposes of subparagraph (1) of this paragraph, the election period under the plan must begin no later than the date the plan amendment is adopted and end no earlier than the latest of the following dates:

(i) The date which is 60 days after the day the plan amendment is adopted,

(ii) The date which is 60 days after the day the plan amendment becomes effective, or

(iii) The date which is 60 days after the day the participant is issued written notice of the plan amendment by the employer or plan administrator.

(3) Service requirement. For purposes of subparagraph (1) of this paragraph, a participant shall be considered to have completed 5 years of service if such participant has completed 5 years of service, whether or not consecutive, without regard to the exceptions of section 411(a)(4) prior to the expiration of the election period described in subparagraph (2) of this paragraph. For the meaning of the term “year of service”, see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(4) Election only by participant. The election described in subparagraph (1) of this paragraph is available only to an individual who is a participant in the plan at the time such election is made.

(5) Election may be irrevocable. A plan, as amended, shall not fail to meet the minimum vesting standards of section 411(a)(2) by reason of section 411(a)(10)(B) merely because such plan provides that the election described in subparagraph (1) of this paragraph is irrevocable.

(6) Relationship with section 411(a)(2). The election described in subparagraph (1) of this paragraph is available for a vesting schedule which does not satisfy the requirements of section 411(a)(2) only if under such schedule all participants have a 50 percent nonforfeitable right after 10 years of service, and a 100 percent nonforfeitable right after 15 years of service, in their employer-derived accrued benefit. If the vesting schedule provides less vesting than the percentages required by the preceding sentence, the plan can be amended to provide for such vesting.

(c) Special rules—(1) Amendment of vesting schedule. For purposes of this section, an amendment of a vesting schedule is each plan amendment which directly or indirectly affects the computation of the nonforfeitable percentage of employees' rights to employer-derived accrued benefits. Consequently, such an amendment, for example, includes each change in the plan which affects either the plan's computation of years of service or of vesting percentages for years of service.

(2) Aggregation of amendments. All plan amendments which are: (i) amendments of a vesting schedule within the meaning of subparagraph (1) of this paragraph and (ii) adopted and effective at the same time, shall be deemed to be a single amendment for purposes of applying the rules in paragraphs (a) and (b) of this section.

(3) Relationship with section 411(d)(6). For additional requirements relating to section 411(d)(6), see § 1.411(d)-3(a)(3).

(a) [Reserved]

(b) Election of former schedule—(1) In general. Under section 411(a)(10)(B), for plan years for which section 411 applies, if the vesting schedule of a plan is amended, the plan will not be treated as meeting the minimum vesting standards of section 411(a)(2) unless the plan as amended provides that each participant whose nonforfeitable percentage of his accrued benefit derived from employer contributions is determined under such schedule, and who has completed at least 3 years of service with the employer, may elect, during the election period, to have the nonforfeitable percentage of his accrued benefit derived from employer contributions determined without regard to such amendment. Notwithstanding the preceding sentence, no election need be provided for any participant whose nonforfeitable percentage under the plan, as amended, at any time cannot be less than such percentage determined without regard to such amendment. For employees not described in § 1.411(a)-3T(e)(1), this section shall be applied by substituting “5 years of service” for “3 years of service” where such language appears.

(2) Election period. For purposes of subparagraph (1) of this paragraph, the election period under the plan must begin no later than the date the plan amendment is adopted and end no earlier than the latest of the following dates:

(i) The date which is 60 days after the day the plan amendment is adopted,

(ii) The date which is 60 days after the day the plan amendment becomes effective, or

(iii) The date which is 60 days after the day the participant is issued written notice of the plan amendment by the employer or plan administrator.

(3) Service requirement. For purposes of subparagraph (1) of this paragraph, a participant shall be considered to have completed 3 years of service if such participant has completed 3 years of service, whether or not consecutive, without regard to the exceptions of section 411(a)(4) prior to the expiration of the election period described in subparagraph (2) of this paragraph. For the meaning of the term “year of service”, see regulations prescribed by the Secretary of Labor under 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(a) Scope—(1) In general. Section 411(a)(11) restricts the ability of a plan to distribute any portion of a participant's accrued benefit without the participant's consent. Section 411(a)(11) also restricts the ability of defined benefit plans to distribute any portion of a participant's accrued benefit in optional forms of benefit without complying with specified valuation rules for determining the amount of the distribution. If the consent requirements or the valuation rules of this section are not satisfied, the plan fails to satisfy the requirements of section 411(a).

(2) Accrued benefit. For purposes of this section, an accrued benefit is valued taking into consideration the particular optional form in which the benefit is to be distributed. The value of an accrued benefit is the present value of the benefit in the distribution form determined under the plan. For example, a plan that provides a subsidized early retirement annuity benefit may specify that the optional single sum distribution form of benefit available at early retirement age is the present value of the subsidized early retirement annuity benefit. In this case, the subsidized early retirement annuity benefit must be used to apply the valuation requirements of this section and the resulting amount of the single sum distribution. However, if a plan that provides a subsidized early retirement annuity benefit specifies that the single sum distribution benefit available at early retirement age is the present value of the normal retirement annuity benefit, then the normal retirement annuity benefit is used to apply the valuation requirements of this section and the resulting amount of the single sum distribution available at early retirement age.

(b) General consent rules. A plan must satisfy the participant consent requirement with respect to the distribution of a participant's nonforfeitable accrued benefit with a present value in excess of the cash-out limit in effect under paragraph (c)(3)(ii) of this section. See paragraphs (c) (3) and (4) for situations where no consent is required.

(c) Consent, etc. requirements—(1) General rule. If an accrued benefit is immediately distributable, section 411(a)(11) permits plans to provide for the distribution of any portion of a participant's nonforfeitable accrued benefits only if the applicable consent requirements are satisfied.

(2) Consent. (i) No consent is valid unless the participant has received a general description of the material features of the optional forms of benefit available under the plan. In addition, so long as a benefit is immediately distributable, a participant must be informed of the right, if any, to defer receipt of the distribution. Furthermore, consent is not valid if a significant detriment is imposed under the plan on any participant who does not consent to a distribution. Whether or not a significant detriment is imposed shall be determined by the Commissioner by examining the particular facts and circumstances.

(ii) Consent of the participant to the distribution must not be made before the participant receives the notice of his or her rights specified in this paragraph (c)(2) and must not be made more than 90 days before the date the distribution commences.

(iii) A plan must provide a participant with notice of the rights specified in this paragraph (c)(2) at a time that satisfies either paragraph (c)(2)(iii)(A) or (B) of this section:

(A) This paragraph (c)(2)(iii)(A) is satisfied if the plan provides a participant with notice of the rights specified in this paragraph (c)(2) no less than 30 days and no more than 90 days before the date the distribution commences. However, if the participant, after having received this notice, affirmatively elects a distribution, a plan will not fail to satisfy the consent requirement of section 411(a)(11) merely because the distribution commences less than 30 days after the notice was provided to the participant, provided the plan administrator clearly indicates to the participant that the participant has a right to at least 30 days to consider whether to consent to the distribution.

(B) This paragraph (c)(2)(iii)(B) is satisfied if the plan—

(1) Provides the participant with notice of the rights specified in this paragraph (c)(2);

(2) Provides the participant with a summary of the notice within the time period described in paragraph (c)(2)(iii)(A) of this section; and

(3) If the participant so requests after receiving the summary described in paragraph (c)(2)(iii)(B)(2) of this section, provides the notice to the participant without charge and no less than 30 days before the date the distribution commences, subject to the rules for the participant's waiver of that 30-day period. The summary described in paragraph (c)(2)(iii)(B)(2) of this section must advise the participant of the right, if any, to defer receipt of the distribution, must set forth a summary of the distribution options under the plan, must refer the participant to the most recent version of the notice (and, in the case of a notice provided in any document containing information in addition to the notice, must identify that document and must provide a reasonable indication of where the notice may be found in that document, such as by index reference or by section heading), and must advise the participant that, upon request, a copy of the notice will be provided without charge.

(iv) For purposes of satisfying the requirements of this paragraph (c)(2), the plan administrator may substitute the annuity starting date, within the meaning of § 1.401(a)-20, Q&A-10, for the date the distribution commences.

(v) See § 1.401(a)-20, Q&A-24 for a special rule applicable to consents to plan loans.

(3) Cash-out limit. (i) Written consent of the participant is required before the commencement of the distribution of any portion of an accrued benefit if the present value of the nonforfeitable total accrued benefit is greater than the cash-out limit in effect under paragraph (c)(3)(ii) of this section on the date the distribution commences. The consent requirements are deemed satisfied if such value does not exceed the cash-out limit, and the plan may distribute such portion to the participant as a single sum. Present value for this purpose must be determined in the same manner as under section 417(e); see § 1.417(e)-1(d).

(ii) The cash-out limit in effect for a date is the amount described in section 411(a)(11)(A) for the plan year that includes that date. The cash-out limit in effect for dates in plan years beginning on or after August 6, 1997, is $5,000. The cash-out limit in effect for dates in plan years beginning before August 6, 1997, is $3,500.

(iii) Effective date. Paragraphs (c)(3)(i) and (ii) of this section apply to distributions made on or after October 17, 2000. However, an employer is permitted to apply the $5,000 cash-out limit described in paragraph (c)(3)(ii) of this section to plan years beginning on or after August 6, 1997. Otherwise, for distributions prior to October 17, 2000, §§ 1.411(a)-11 and 1.411(a)-11T in effect prior to October 17, 2000 (as contained in 26 CFR Part 1 revised as of April 1, 2000) apply.

(4) Immediately distributable. Participant consent is required for any distribution while it is immediately distributable, i.e., prior to the later of the time a participant has attained normal retirement age (as defined in section 411(a)(8)) or age 62. Once a distribution is no longer immediately distributable, a plan may distribute the benefit in the form of a QJSA in the case of a benefit subject to section 417 or in the normal form in other cases without consent.

(5) Death of participant. The consent requirements of section 411(a)(11) do not apply after the death of the participant.

(6) QDROs. The consent requirements of section 411(a)(11) do not apply to payments to an alternate payee, defined in section 414(p)(8), except as provided in a qualified domestic relations order pursuant to section 414(p).

(7) Section 401(a)(9), etc. The consent requirements of section 411(a)(11) do not apply to the extent that a distribution is required to satisfy the requirements of section 401(a)(9) or 415. See section 401(a)(9) and the regulations thereunder and § 1.401(a)-20 Q&A 23 for guidance on these requirements. Notwithstanding any provision to the contrary in section 401(a)(14) or § 1.401(a)-14, a plan may not distribute a participant's nonforfeitable accrued benefit with a present value in excess of the cash-out limit in effect under paragraph (c)(3)(ii) of this section while the benefit is immediately distributable unless the participant consents to such distribution. The failure of a participant to consent is deemed to be an election to defer commencement of payment of the benefit for purposes of section 401(a)(14) and § 1.401(a)-14.

(8) Delegation to Commissioner. The Commissioner, in revenue rulings, notices, and other guidance published in the Internal Revenue Bulletin, may modify, or provide additional guidance with respect to, the notice and consent requirements of this section. See § 601.601(d)(2)(ii)(b) of this chapter.

(d) Distribution valuation requirements. In determining the present value of any distribution of any accrued benefit from a defined benefit plan, the plan must take into account specified valuation rules. For this purpose, the valuation rules are the same valuation rules for valuing distributions as set forth in section 417(e); see § 1.417(e)-1(d). This paragraph (d) applies both before and after the participant's death regardless of whether the accrued benefit is immediately distributable. This paragraph also applies whether or not the participant's consent is required under paragraphs (b) and (c) of this section.

(e) Special rules—(1) Plan termination. The requirements of this section apply before, on and after a plan termination. If a defined contribution plan terminates and the plan does not offer an annuity option (purchased from a commercial provider), then the plan may distribute a participant's accrued benefit without the participant's consent. The preceding sentence does not apply if the employer, or any entity within the same controlled group as the employer, maintains another defined contribution plan, other than an employee stock ownership plan (as defined in section 4975(e)(7)). In such a case, the participant's accrued benefit may be transferred without the participant's consent to the other plan if the participant does not consent to an immediate distribution from the terminating plan. See section 411(d)(6) and the regulations thereunder for other rules applicable to transferee plans and plan terminations.

(2) ESOP dividends. The requirements of this section do not apply to any distribution of dividends to which section 404(k) applies.

(3) Other rules. See § 1.401(a)-20 Q&As 14, 17 and 24 for other rules that apply to the section 411(a)(11) requirements.

(f) Medium for notice and consent—(1) Notice. The notice of a participant's rights described in paragraph (c)(2) of this section or the summary of that notice described in paragraph (c)(2)(iii)(B)(2) of this section must be provided on a written paper document. However, see § 1.401(a)-21 of this chapter for rules permitting the use of electronic media to provide applicable notices to recipients with respect to retirement plans.

(2) Consent. The consent described in paragraphs (c)(2) and (3) of this section must be given on a written paper document. However, see § 1.401(a)-21 of this chapter for rules permitting the use of electronic media to make participant elections with respect to retirement plans.

(a) In general. This section sets forth certain rules that apply to statutory hybrid plans under section 411(a)(13). Paragraph (b) of this section describes special rules for certain statutory hybrid plans that determine benefits under a lump sum-based benefit formula. Paragraph (c) of this section describes the vesting requirement for statutory hybrid plans. Paragraphs (d) and (e) of this section contain definitions and effective/applicability dates, respectively.

(b) Calculation of benefit by reference to hypothetical account balance or accumulated percentage—(1) Payment of a current balance or current value under a lump sum-based benefit formula. Pursuant to section 411(a)(13)(A), a statutory hybrid plan that determines any portion of a participant's benefits under a lump sum-based benefit formula is not treated as failing to meet the following requirements solely because, with respect to benefits determined under that formula, the present value of those benefits is, under the terms of the plan, equal to the then-current balance of the hypothetical account maintained for the participant or to the then-current value of the accumulated percentage of the participant's final average compensation under that formula—

(i) Section 411(a)(2); or

(ii) With respect to the participant's accrued benefit derived from employer contributions, section 411(a)(11), 411(c), or 417(e).

(2) General rules with respect to current account balance or current value—(i) Benefit after normal retirement age. The relief of section 411(a)(13) does not override the requirement for a plan that, with respect to a participant with an annuity starting date after normal retirement age, the plan either provide an actuarial increase after normal retirement age or satisfy the requirements for suspension of benefits under section 411(a)(3)(B). Accordingly, with respect to such a participant, a plan with a lump sum based benefit formula violates the requirements of section 411(a) if the balance of the hypothetical account or the value of the accumulated percentage of the participant's final average compensation is not increased sufficiently to satisfy the requirements of section 411(a)(2) for distributions commencing after normal retirement age, unless the plan suspends benefits in accordance with section 411(a)(3)(B).

(ii) Reductions limited. The relief of section 411(a)(13) does not permit the accumulated benefit under a lump sum-based benefit formula to be reduced in a manner that would be prohibited if that reduction were applied to the accrued benefit. Accordingly, the only reductions that can apply to the balance of the hypothetical account or accumulated percentage of the participant's final average compensation are reductions as a result of—

(A) Benefit payments;

(B) Qualified domestic relations orders under section 414(p);

(C) Forfeitures that are permitted under section 411(a) (such as charges for providing a qualified preretirement survivor annuity);

(D) Amendments that would reduce the accrued benefit but that are permitted under section 411(d)(6);

(E) Adjustments resulting in a decrease in the balance of the hypothetical account due to the application of interest credits (as defined in § 1.411(b)(5)-1(d)(1)(ii)(A)) that are negative for an interest crediting period;

(F) In the case of a formula that expresses the accumulated benefit as an accumulated percentage of the participant's final average compensation, adjustments resulting in a decrease in the dollar amount of the accumulated percentage of the participant's final average compensation—

(1) Due to a decrease in the dollar amount of the participant's final average compensation; or

(2) Due to an increase in the integration level, under a formula that is integrated with Social Security (for example, as a result of an increase in the Social Security taxable wage base or in Social Security covered compensation); or

(G) Other reductions to the extent provided by the Commissioner in revenue rulings, notices, or other guidance published in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii)(b)).

(3) Payment of benefits based on current account balance or current value—(i) Optional forms that are actuarially equivalent. With respect to the benefits under a lump sum-based benefit formula, the relief of paragraph (b)(1) of this section applies to an optional form of benefit that is determined as of the annuity starting date as the actuarial equivalent, using reasonable actuarial assumptions, of the then-current balance of a hypothetical account maintained for the participant or the then-current value of an accumulated percentage of the participant's final average compensation.

(ii) Optional forms that are subsidized. With respect to the benefits under a lump sum-based benefit formula, if an optional form of benefit is payable in an amount that is greater than the actuarial equivalent, determined using reasonable actuarial assumptions, of the then-current balance of a hypothetical account maintained for the participant or the then-current value of an accumulated percentage of the participant's final average compensation, then the plan satisfies the requirements of sections 411(a)(2), 411(a)(11), 411(c) and 417(e) with respect to the amount of that optional form of benefit. However, see § 1.411(b)(5)-1(b)(1)(iii) for rules relating to early retirement subsidies.

(iii) Optional forms that are less valuable. Except as otherwise provided in paragraph (b)(4)(i) of this section, if an optional form of benefit is not at least the actuarial equivalent, using reasonable actuarial assumptions, of the then-current balance of a hypothetical account maintained for the participant or the then-current value of an accumulated percentage of the participant's final average compensation, then the relief under section 411(a)(13) (permitting a plan to treat the account balance or accumulated percentage as the actuarial equivalent of the portion of the accrued benefit determined under the lump sum-based benefit formula) does not apply in determining whether the optional form of benefit is the actuarial equivalent of the portion of the accrued benefit determined under the lump sum-based benefit formula. As a result, payment of that optional form of benefit must satisfy the rules applicable to payment of the accrued benefit generally under a defined benefit plan (without regard to the special rules of section 411(a)(13)(A) and paragraph (b)(1) of this section), including the requirements of section 411(a)(2) and, for optional forms subject to the minimum present value requirements of section 417(e)(3), those minimum present value requirements.

(4) Rules of application—(i) Relief applies on proportionate basis with respect to payment of only a portion of the benefit under a lump sum-based benefit formula. The relief of paragraph (b)(1) of this section applies on a proportionate basis to a payment of a portion of the benefit under a lump sum-based benefit formula, such as a payment of a specified dollar amount or percentage of the then-current balance of a hypothetical account maintained for the participant or then-current value of an accumulated percentage of the participant's final average compensation. Thus, for example, if a plan that expresses the participant's entire accumulated benefit as the balance of a hypothetical account distributes 40 percent of the participant's then-current hypothetical account balance in a single payment, the plan is treated as satisfying the requirements of section 411(a) and the minimum present value rules of section 417(e) with respect to 40 percent of the participant's then-current accrued benefit.

(ii) Relief applies only to portion of benefit determined under lump sum-based benefit formula. The relief of paragraph (b)(1) of this section generally applies only to the portion of the participant's benefit that is determined under a lump sum-based benefit formula and generally does not apply to any portion of the participant's benefit that is determined under a formula that is not a lump sum-based benefit formula. The following rules apply for purposes of satisfying section 417(e):

(A) “Greater-of” formulas. If the participant's accrued benefit equals the greater of the accrued benefit under a lump sum-based benefit formula and the accrued benefit under another formula that is not a lump-sum based benefit formula, a single-sum payment of the participant's entire benefit must be no less than the greater of the then-current accumulated benefit under the lump sum-based benefit formula and the present value, determined in accordance with section 417(e), of the benefit under the other formula. For example, assume that the accrued benefit under a plan is determined as the greater of the accrued benefit attributable to the balance of a hypothetical account and the accrued benefit equal to a pro rata portion of a normal retirement benefit determined by projecting the hypothetical account balance (including future principal and interest credits) to normal retirement age. In such a case, a single-sum payment of the participant's entire benefit must be no less than the greater of the then-current balance of the hypothetical account and the present value, determined in accordance with section 417(e), of the pro rata benefit determined by projecting the hypothetical account balance to normal retirement age.

(B) “Sum-of” formulas. If the participant's accrued benefit equals the sum of the accrued benefit under a lump sum-based benefit formula and the accrued benefit under another formula that is not a lump-sum based benefit formula, a single-sum payment of the participant's entire benefit must be no less than the sum of the then-current accumulated benefit under the lump sum-based benefit formula and the present value, determined in accordance with section 417(e), of the benefit under the other formula. For example, assume that the accrued benefit under a plan is determined as the sum of the accrued benefit attributable to the balance of a hypothetical account and the accrued benefit equal to the excess of the benefit under another formula over the benefit under the hypothetical account formula. In such a case, a single-sum payment of the participant's entire benefit must be no less than the sum of the then-current balance of the hypothetical account and the present value, determined in accordance with section 417(e), of the excess of the benefit under the other formula over the benefit under the hypothetical account formula.

(C) “Lesser-of” formulas. If the participant's accrued benefit equals the lesser of the accrued benefit under a lump sum-based benefit formula and the accrued benefit under another formula that is not a lump-sum based benefit formula, a single-sum payment of the participant's entire benefit must be no less than the lesser of the then-current accumulated benefit under the lump sum-based benefit formula and the present value, determined in accordance with section 417(e), of the benefit under the other formula. For example, assume that the accrued benefit under a plan is determined as the accrued benefit attributable to the balance of a hypothetical account, but no greater than an accrued benefit payable at normal retirement age in the form of a straight life annuity of $100,000 per year. In such a case, a single-sum payment of the participant's entire benefit must be no less than the lesser of the then-current balance of the hypothetical account and the present value, determined in accordance with section 417(e), of a benefit payable at normal retirement age in the form of a straight life annuity of $100,000 per year. If the formula that is not a lump sum-based benefit formula is the maximum annual benefit described in section 415(b), then the single-sum payment of the participant's entire benefit must not exceed the then-current accumulated benefit under the lump sum-based benefit formula.

(c) Three-year vesting requirement—(1) In general. Pursuant to section 411(a)(13)(B), if any portion of the participant's accrued benefit under a defined benefit plan is determined under a statutory hybrid benefit formula, the plan is treated as failing to satisfy the requirements of section 411(a)(2) unless the plan provides that the participant has a nonforfeitable right to 100 percent of the participant's accrued benefit if the participant has three or more years of service. Thus, this 3-year vesting requirement applies with respect to the entire accrued benefit of a participant under a defined benefit plan even if only a portion of the participant's accrued benefit under the plan is determined under a statutory hybrid benefit formula. Similarly, if the participant's accrued benefit under a defined benefit plan is, under the plan's terms, the larger of two (or more) benefit amounts, where each amount is determined under a different benefit formula (including a benefit determined pursuant to an offset among formulas within the plan or a benefit determined as the greater of a protected benefit under section 411(d)(6) and another benefit amount) and at least one of those formulas is a statutory hybrid benefit formula, the participant's entire accrued benefit under the defined benefit plan is subject to the 3-year vesting rule of section 411(a)(13)(B) and this paragraph (c). The rule described in the preceding sentence applies even if the larger benefit is ultimately the benefit determined under a formula that is not a statutory hybrid benefit formula.

(2) Examples. The provisions of this paragraph (c) are illustrated by the following examples:

(d) Definitions—(1) In general. The definitions in this paragraph (d) apply for purposes of this section.

(2) Accumulated benefit. A participant's accumulated benefit at any date means the participant's benefit, as expressed under the terms of the plan, accrued to that date. For this purpose, if a participant's benefit is expressed under the terms of the plan as the current balance of a hypothetical account or the current value of an accumulated percentage of the participant's final average compensation, the participant's accumulated benefit is expressed in that manner regardless of how the plan defines the participant's accrued benefit. Thus, for example, the accumulated benefit of a participant may be expressed under the terms of the plan as either the current balance of a hypothetical account or the current value of an accumulated percentage of the participant's final average compensation, even if the plan defines the participant's accrued benefit as an annuity beginning at normal retirement age that is actuarially equivalent to that balance or value.

(3) Lump sum-based benefit formula— (i) In general. A lump sum-based benefit formula means a benefit formula used to determine all or any part of a participant's accumulated benefit under a defined benefit plan under which the accumulated benefit provided under the formula is expressed as the current balance of a hypothetical account maintained for the participant or as the current value of an accumulated percentage of the participant's final average compensation. A benefit formula is expressed as the current balance of a hypothetical account maintained for the participant if it is expressed as a current single-sum dollar amount equal to that balance. A benefit formula is expressed as the current value of an accumulated percentage of the participant's final average compensation if it is expressed as a current single-sum dollar amount equal to a percentage of the participant's final average compensation or, for plan years described in paragraph (e)(2)(ii)(A) or (e)(2)(ii)(B) of this section, as applicable (or any earlier date as elected by the taxpayer), a percentage of the participant's highest average compensation (regardless of whether the plan applies a limitation on the past period for which compensation is taken into account in determining highest average compensation). Whether a benefit formula is a lump sum-based benefit formula is determined based on how the accumulated benefit of a participant is expressed under the terms of the plan, and does not depend on whether the plan provides an optional form of benefit in the form of a single-sum payment. However, for plan years described in paragraph (e)(2)(ii)(A) or (e)(2)(ii)(B) of this section (as applicable), a benefit formula does not constitute a lump sum-based benefit formula unless a distribution of the benefits under that formula in the form of a single-sum payment equals the accumulated benefit under that formula (except to the extent the single-sum payment is greater to satisfy the requirements of section 411(d)(6)). In addition, for plan years described in paragraph (e)(2)(ii)(A) or (e)(2)(ii)(B) of this section (as applicable), a benefit formula does not constitute a lump sum-based benefit formula unless the portion of the participant's accrued benefit that is determined under that formula and the then-current balance of the hypothetical account or the then-current value of the accumulated percentage of the participant's final average compensation are actuarially equivalent (determined using reasonable actuarial assumptions) either—

(A) Upon attainment of normal retirement age; or

(B) At the annuity starting date for a distribution with respect to that portion.

(ii) Exception for employee contributions. For purposes of the definition of a lump sum-based benefit formula in paragraph (d)(3)(i) of this section, the benefit properly attributable to after-tax employee contributions, rollover contributions from eligible retirement plans under section 402(c)(8), and other similar employee contributions (such as repayments of distributions pursuant to section 411(a)(7)(C) and employee contributions that are pickup contributions pursuant to section 414(h)(2)) is disregarded. However, a benefit is not properly attributable to contributions described in this paragraph (d)(3)(ii) if the contributions are credited with interest at a rate that exceeds a reasonable rate of interest or if the conversion factors used to calculate such benefit are not actuarially reasonable. See section 411(c) for an example of a calculation of a benefit that is properly attributable to employee contributions.

(4) Statutory hybrid benefit formula—(i) In general. A statutory hybrid benefit formula means a benefit formula that is either a lump sum-based benefit formula or a formula that is not a lump sum-based benefit formula but that has an effect similar to a lump sum-based benefit formula.

(ii) Effect similar to a lump sum-based benefit formula— (A) In general. Except as provided in paragraphs (d)(4)(ii)(B) through (E) of this section, a benefit formula under a defined benefit plan that is not a lump sum-based benefit formula has an effect similar to a lump sum-based benefit formula if the formula provides that a participant's accumulated benefit is expressed as a benefit that includes the right to adjustments (including a formula that provides for indexed benefits under § 1.411(b)(5)-1(b)(2)) for a future period and the total dollar amount of those adjustments is reasonably expected to be smaller for the participant than for any similarly situated, younger individual (within the meaning of § 1.411(b)(5)-1(b)(5)) who is or could be a participant in the plan. For this purpose, the right to adjustments for a future period means, for plan years described in paragraph (e)(2)(ii)(A) or (e)(2)(ii)(B) of this section (as applicable), the right to any changes in the dollar amount of benefits over time, regardless of whether those adjustments are denominated as interest credits. A benefit formula that does not include adjustments for any future period is treated as a formula with an effect similar to a lump sum-based benefit formula if the formula would be described in this paragraph (d)(4)(ii)(A) except for the fact that the adjustments are provided pursuant to a pattern of repeated plan amendments. See § 1.411(d)-4, A-1(c)(1).

(B) Exception for post-retirement benefit adjustments. Post-annuity starting date adjustments in the amount payable to a participant (such as cost-of-living increases) are disregarded in determining whether a benefit formula under a defined benefit plan has an effect similar to a lump sum-based benefit formula.

(C) Exception for certain variable annuity benefit formulas. If a variable annuity benefit formula adjusts benefits by reference to the difference between a rate of return on plan assets (or specified market indices) and a specified assumed interest rate of 5 percent or higher, then the variable annuity benefit formula is not treated as being reasonably expected to provide a smaller total dollar amount of future adjustments for the participant than for any similarly situated, younger individual who is or could be a participant in the plan, and thus such a variable annuity benefit formula does not have an effect similar to a lump sum-based benefit formula. For plan years described in paragraph (e)(2)(ii)(A) or (e)(2)(ii)(B) of this section (as applicable) (or any earlier date as elected by the taxpayer), the rate of return on plan assets (or specified market index) by reference to which the benefit formula adjusts must be a rate of return described in § 1.411(b)(5)-1(d)(5) (which includes, in the case of a benefit formula determined with reference to an annuity contract for an employee issued by an insurance company licensed under the laws of a State, the rate of return on the market index specified under that contract).

(D) Exception for employee contributions. Benefits that are disregarded under paragraph (d)(3)(ii) of this section (benefits properly attributable to certain employee contributions) are also disregarded for purposes of determining whether a benefit formula has an effect similar to a lump sum-based benefit formula.

(E) Exception for certain actuarial reductions for early commencement under traditional formula. A defined benefit formula is not treated as having an effect similar to a lump sum-based benefit formula with respect to a participant merely because the formula provides for a reduction in the benefit payable at early retirement due to early commencement (with the result that the benefit payable at normal retirement age is greater than the benefit payable at early retirement), provided that the benefit payable at normal retirement age to the participant cannot be less than the benefit payable at normal retirement age to any similarly situated, younger individual who is or could be a participant in the plan. Thus, for example, a plan that provides a benefit equal to 1 percent of final average pay per year of service, payable as a life annuity at normal retirement age, is not treated as having an effect similar to a lump sum-based benefit formula by reason of an actuarial reduction in the benefit payable under the plan for early commencement.

(5) Statutory hybrid plan. A statutory hybrid plan means a defined benefit plan that contains a statutory hybrid benefit formula.

(6) Variable annuity benefit formula. A variable annuity benefit formula means any benefit formula under a defined benefit plan which provides that the amount payable is periodically adjusted by reference to the difference between a rate of return and a specified assumed interest rate.

(e) Effective/applicability date—(1) Statutory effective/applicability date—(i) In general. Except as provided in paragraphs (e)(1)(ii) and (e)(1)(iii) of this section, section 411(a)(13) applies for periods beginning on or after June 29, 2005.

(ii) Calculation of benefits. Section 411(a)(13)(A) applies to distributions made after August 17, 2006.

(iii) Vesting—(A) Plans in existence on June 29, 2005—(1) General rule. In the case of a plan that is in existence on June 29, 2005 (regardless of whether the plan is a statutory hybrid plan on that date), section 411(a)(13)(B) applies to plan years that begin on or after January 1, 2008.

(2) Exception for plan sponsor election. See § 1.411(b)(5)-1(f)(1)(iii)(A)(2) for a special election for early application of section 411(a)(13)(B).

(B) Plans not in existence on June 29, 2005. In the case of a plan not in existence on June 29, 2005, section 411(a)(13)(B) applies to plan years that end on or after June 29, 2005.

(C) Collectively bargained plans. Notwithstanding paragraphs (e)(1)(iii)(A) and (B) of this section, in the case of a collectively bargained plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified on or before August 17, 2006, the requirements of section 411(a)(13)(B) do not apply to plan years that begin before the earlier of—

(1) The later of—

(i) The date on which the last of those collective bargaining agreements terminates (determined without regard to any extension thereof on or after August 17, 2006); or

(ii) January 1, 2008; or

(2) January 1, 2010.

(D) Treatment of plans with both collectively bargained and non-collectively bargained employees. In the case of a plan with respect to which a collective bargaining agreement applies to some, but not all, of the plan participants, the plan is considered a collectively bargained plan for purposes of paragraph (e)(1)(iii)(C) of this section if it is considered a collectively bargained plan under the rules of § 1.436-1(a)(5)(ii)(B).

(E) Hour of service required. Section 411(a)(13)(B) does not apply to a participant who does not have an hour of service after section 411(a)(13)(B) would otherwise apply to the participant under the rules of paragraph (e)(1)(iii)(A), (B), or (C) of this section.

(2) Effective/applicability date of regulations—(i) In general. Except as provided in paragraph (e)(2)(ii) of this section, this section applies to plan years that begin on or after January 1, 2011. For the periods after the statutory effective date set forth in paragraph (e)(1) of this section and before the regulatory effective date set forth in the preceding sentence, the relief of section 411(a)(13)(A) applies and the 3-year vesting requirement of section 411(a)(13)(B) must be satisfied. During these periods, a plan is permitted to rely on the provisions of this section for purposes of applying the relief of section 411(a)(13)(A) and satisfying the requirements of section 411(a)(13)(B).

(ii) Special effective date—(A) In general. Except as otherwise provided in this paragraph (e)(2)(ii), paragraphs (b)(2), (3), and (4) of this section apply to plan years that begin on or after January 1, 2017.

(B) Collectively bargained plans. In the case of a plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified on or before November 13, 2015, that constitutes a collectively bargained plan under the rules of § 1.436-1(a)(5)(ii)(B), paragraphs (b)(2), (3), and (4) of this section apply to plan years that begin on or after the later of—

(1) January 1, 2017; and

(2) The earlier of—

(i) January 1, 2019; and

(ii) The date on which the last of those collective bargaining agreements terminates (determined without regard to any extension thereof on or after November 13, 2015).

(iii) Hour of service required. A benefit formula is not treated as having an effect similar to a lump sum-based benefit formula under paragraph (d)(4)(ii) of this section with respect to a participant who does not have an hour of service after the regulatory effective date set forth in paragraph (e)(2)(i) of this section.

(a) Accrued benefit requirements—(1) In general. Under section 411(b), for plan years beginning after the applicable effective date of section 411, rules are provided for the determination of the accrued benefit to which a participant is entitled under a plan. Under a defined contribution plan, a participant's accrued benefit is the balance to the credit of the participant's account. Under a defined benefit plan, a participant's accrued benefit is his accrued benefit determined under the plan. A defined benefit plan is not a qualified plan unless the method provided by the plan for determining accrued benefits satisfies at least one of the alternative methods (described in paragraph (b) of this section) for determining accrued benefits with respect to all active participants under the plan. A defined benefit plan may provide that accrued benefits for participants are determined under more than one plan formula. In such a case, the accrued benefits under all such formulas must be aggregated in order to determine whether or not the accrued benefits under the plan for participants satisfy one of the alternative methods. A plan may satisfy different methods with respect to different classifications of employees, or separately satisfy one method with respect to the accrued benefits for each such classification, provided that such classifications are not so structured as to evade the accrued benefit requirements of section 411(b) and this section. (For example, if a plan provides that employees who commence participation at or before age 40 accrue benefits in a manner which satisfies the 133 1/3 percent method of determining accrued benefits and employees who commence participation after age 40 accrue benefits in a manner which satisfies the 3 percent method of determining accrued benefits, the plan would be so structured as to evade the requirements of section 411(b).) A defined benefit plan does not satisfy the requirements of section 411(b) and this section merely because the accrued benefit is defined as the “reserve under the plan”. Special rules are provided for the first two years of service by a participant, certain insured defined benefit plans, and certain reductions in accrued benefits due to increasing age or service. In addition, a special rule is provided with respect to accruals for service before the effective date of section 411.

(2) Cross references—(i) 3 percent method. For rules relating to the 3 percent method of determining accrued benefits, see paragraph (b)(1) of this section.

(ii) 133 1/3 percent method. For rules relating to the 133 1/3 percent method of determining accrued benefits, see paragraph (b)(2) of this section.

(iii) Fractional method. For rules relating to the fractional method of determining accrued benefits, see paragraph (b)(3) of this section.

(iv) Accruals before effective date. For rules relating to accruals for service before the effective date of section 411, see paragraph (c) of this section.

(v) First 2 years of service. For special rules relating to determination of accrued benefit for first 2 continuous years of service, see paragraph (d)(1) of this section.

(vi) Certain insured plans. For special rules relating to determination of accrued benefit under a defined benefit plan funded exclusively by insurance contracts, see paragraph (d)(2) of this section.

(vii) Accruals decreased by increasing age or service. For special rules relating to prohibition of decrease in accrued benefit on account of increasing age or service, see paragraph (d)(3) of this section.

(viii) Separate accounting. For rules relating to requirements for separate accounting, see paragraph (e) of this section.

(ix) Year of participation. For definition of “year of participation”, see paragraph (f) of this section.

(b) Defined benefit plans. A defined benefit plan satisfies the requirements of section 411(b)(1) and this paragrah for a plan year to which section 411 and this section apply if it satisfies the requirements of subparagraph (1), (2), or (3) of this paragraph for such year.

(1) 3 percent method—(i) General rule. A defined benefit plan satisfies the requirements of this paragraph for a plan year if, as of the close of the plan year, the accrued benefit to which each participant is entitled, computed as if the participant separated from the service as of the close of such plan year, is not less than 3 percent of the 3 percent method benefit, multiplied by the number of years (not in excess of 33 1/3) of his participation in the plan including years after his normal retirement age. For purposes of this subparagraph, the “3 percent method benefit” is the normal retirement benefit to which the participant would be entitled if he commenced participation at the earliest possible entry age for any individual who is or could be a participant under the plan and if he served continuously until the earlier of age 65 or the normal retirement age under the plan.

(ii) Special rules—(A) Compensation. In the case of a plan providing a retirement benefit based upon compensation during any period, the normal retirement benefit to which a participant would be entitled is determined as if he continued to earn annually the average rate of compensation which he earned during consecutive years of service, not in excess of 10, for which his compensation was the highest. For purposes of this subdivision (A), the number of consecutive years of service used in computing average compensation shall be the number of years of service specified under the plan (not in excess of 10) for computing normal retirement benefits.

(B) Social security, etc. For purposes of this subparagraph, for any plan year, social security benefits and all relevant factors used to compute benefits, e.g., consumer price index, are treated as remaining constant as of the beginning of the current plan year for all subsequent plan years.

(C) Computation in certain cases. In the case of any plan to which the provisions of section 411(b)(1)(D) and paragraph (c) of this section are applicable, for any plan year the accrued benefit of any participant shall not be less than the accrued benefit otherwise determined under this subparagraph, reduced by the excess of the accrued benefit determined under this subparagraph as of the first day of the first plan year to which section 411 applies over the accrued benefit determined under section 411(b)(1)(D) and paragraph (c) of this section and increased by the amount determined under paragraph (c)(2)(v) of this section.

(iii) Examples. The application of this subparagraph is illustrated by the following examples.

(2) 133 1/3 percent rule—(i) General rule. A defined benefit plan satisfies the requirements of this subparagraph for a particular plan year if—

(A) Under the plan the accrued benefit payable at the normal retirement age (determined under the plan) is equal to the normal retirement benefit (determined under the plan), and

(B) The annual rate at which any individual who is or could be a participant can accrue the retirement benefits payable at normal retirement age under the plan for any later plan year cannot be more than 133 1/3 percent of the annual rate at which he can accrue benefits for any plan year beginning on or after such particular plan year and before such later plan year.

(ii) Special rules. For purposes of this subparagraph—

(A) Plan amendments. Any amendment to the plan which is in effect for the current plan year shall be treated as if it were in effect for all other plan years.

(B) Change in accrual rate. Any change in an accrual rate which change does not apply to any individual who is of could be a participant in the plan year is disregarded. Thus, for example, if for its plan year beginning January 1, 1980, a defined benefit plan provides an accrued benefit in plan year 1980 of 2 percent of a participant's average compensation for his highest 3 years of compensation for each year of service and provides that in plan year 1981 the accrued benefit will be 3 percent of such average compensation, the plan will not be treated as failing to satisfy the requirements of this subparagraph for plan year 1980 because in plan year 1980 the change in the accrual rate does not apply to any individual who is or could be a participant in plan year 1980. However, if, for example, a defined benefit plan provided for an accrued benefit of 1 percent of a participant's average compensation for his highest 3 years of compensation for each of the first 10 years of service and 1.5 percent of such average compensations for each year of service thereafter, the plan will be treated as failing to satisfy the requirements of this subparagraph for the plan year even though no participant is actually accruing at the 1.5 percent rate because an individual who could be a participant and who had over 10 years of service would accrue at the 1.5 percent rate, which rate exceeds 133 1/3 percent of the 1 percent rate.

(C) Early retirement benefits. The fact that certain benefits under the plan may be payable to certain participants before normal retirement age is disregarded. Thus, the requirements of subdivision (i) of this subparagraph must be satisfied without regard to any benefit payable prior to the normal retirement benefit (such as an early retirement benefit which is not the normal retirement benefit (see § 1.411(a)-7(c).

(D) Social security, etc. For purposes of this paragraph, for any plan year, social security benefits and all relevant factors used to compute benefits, e.g., consumer price index, are treated as remaining constant as of the beginning of the current plan year for all subsequent plan years.

(E) Postponed retirement. A plan shall not be treated as failing to satisfy the requirements of this subparagraph for a plan year merely because no benefits under the plan accrue to a participant who continues service with the employer after such participant has attained normal retirement age.

(F) Computation of benefit. A plan shall not satisfy the requirements of this subparagraph if the base for the computation of retirement benefits changes solely by reason of an increase in the number of years of participation. Thus, for example, a plan will not satisfy the requirements of this subparagraph if it provides a benefit, commencing at normal retirement age, of the sum of (1) 1 percent of average compensation for a participant's first 3 years of participation multiplied by his first 10 years of participation (or, if less than 10 his total years of participation) and (2) 1 percent of average compensation for a participant's 3 highest years of participation multiplied by each year of participation subsequent to the 10th year.

(G) Variable interest crediting rate under a statutory hybrid benefit formula. For plan years that begin on or after January 1, 2012 (or an earlier date as elected by the taxpayer), a plan that determines any portion of the participant's accrued benefit pursuant to a statutory hybrid benefit formula (as defined in § 1.411(a)(13)-1(d)(4)) that utilizes an interest crediting rate described in § 1.411(b)(5)-1(d) that is a variable rate that was less than zero for the prior plan year is not treated as failing to satisfy the requirements of paragraph (b)(2) of this section for the current plan year merely because the plan assumes for purposes of paragraph (b)(2) of this section that the variable rate is zero for the current plan year and all future plan years.

(H) Special rule for multiple formulas. [Reserved]

(iii) Examples. The application of this subparagraph is illustrated by the following examples:

(3) Fractional rule—(i) In general. A defined benefit plan satisfies the requirements of this paragraph if the accrued benefit to which any participant is entitled is not less than the fractional rule benefit multiplied by a fraction (not exceeding 1)—

(A) The numerator of which is his total number of years of participation in the plan, and

(B) The denominator of which is the total number of years he would have participated in the plan if he separated from the service at the normal retirement age under the plan.

(ii) Special rules. For purposes of this subparagraph—

(A) Fractional rule benefit. The “fractional rule benefit” is the annual benefit commencing at the normal retirement age under the plan to which a participant would be entitled if he continued to earn annually until such normal retirement age the same rate of compensation upon which his normal retirement benefit would be computed. Such rate of compensation shall be computed on the basis of compensation taken into account under the plan (but taking into account average compensation for no more than the 10 years of service immediately preceding the determination). For purposes of this subdivision (A), the normal retirement benefit shall be determined as if the participant had attained normal retirement age on the date any such determination is made.

(B) Social security, etc. For purposes of this subparagraph, for any plan year, social security benefits and all relevant factors used to compute benefits, e.g., consumer price index, are treated as remaining constant as of the beginning of the current plan year for all subsequent plan years.

(C) Postponed retirement. A plan shall not be treated as failing to satisfy the requirements of this subparagraph merely because no benefits under the plan accrue to a participant who continues service with the employer after such participant has attained normal retirement age under the plan.

(D) Computation in certain cases. In the case of any plan to which the provisions of section 411(b)(1)(D) and paragraph (c) of this section are applicable, for any plan year the accrued benefit of any participant shall not be less than the accrued benefit otherwise determined under this subparagraph, reduced by the excess of the accrued benefit determined under this subparagraph as of the first day of the first plan year to which section 411 applies over the accrued benefit determined under section 411(b)(1)(D) and paragraph (c) of this section and increased by the amount determined under paragraph (c)(2)(v) of this section.

(iii) Examples. The application of this subparagraph is illustrated by the following examples:

(c) Accruals for service before effective date—(1) General rule. For a plan year to which section 411 applies, a defined benefit plan does not satisfy the requirements of section 411(b)(1) and this section unless, under the plan, the accrued benefit of each participant for plan years beginning before section 411 applies is not less than the greater of—

(i) Such participant's accrued benefit (as of the day before section 411 applies) determined under the plan as in effect from time to time prior to September 2, 1974 (without regard to any amendment adopted after such date), or

(ii) One-half of the accrued benefit that would be determined with respect to the participant as of the day before section 411 applies if the participant's accrued benefit were computed for such prior plan years under a method which satisfies the requirements of section 411(b)(1) (A), (B), or (C) and paragraph (b) (1), (2), or (3) of this section. See 29 CFR Part 2530, Department of Labor regulations relating to minimum standards for employee pension benefit plans, for time participation deemed to begin.

(2) Special rules—(i) A plan shall not be deemed to fail to satisfy the requirements of section 411(b) and this section merely because the method for computing the accrued benefit of a participant for years of participation prior to the first plan year for which section 411 is effective with respect to the plan is not the same method for computing the accrued benefit of a participant for years of participation subsequent to such plan year.

(ii) For purposes of paragraph (c)(1)(ii) of this section, section 411(b)(1)(A) and paragraph (b)(1) of this section shall be applied as if the participant separated from service with the employer on the day before the first day of the first plan year to which section 411 applies.

(iii) For purposes of paragraph (c)(1)(ii) of this section, section 411(b)(1)(B) and paragraph (b)(2) of this section shall be applied in the following manner:

(A) Except as provided in (c)(2)(iii)(B) of this section, section 411(b)(1)(B) and paragraph (b)(2) of this section shall be applied as if the participant separated from service with the employer on the day before the first day of the first plan year to which section 411 applies.

(B) In the case that the plan does not satisfy the requirements of section 411(b)(1)(B) and paragraph (b)(2) of this section at any time prior to the day specified in (c)(2)(iii)(A) of this section, the plan shall be deemed revised to the extent necessary to satisfy the requirements of section 411(b)(1)(B) and paragraph (b)(2) of this section for all plan years beginning before the applicable effective date of section 411 and this section. For purposes of the preceding sentence, a plan shall not be deemed revised to the extent necessary to satisfy the requirements of section 411(b)(1)(B) and paragraph (b)(2) of this section for a plan year if the benefit a participant would receive if he were employed until normal retirement age is reduced by such revision or if the revised rate of accrual with respect to such accrued benefit does not otherwise satisfy the requirements of section 411(b)(1)(B) and paragraph (b)(2) of this section.

(iv) For purposes of paragraph (c)(1)(ii) of this section, section 411(b)(1)(C) and paragraph (b)(3) of this section shall be applied as if the participant separated from service on the day before the first day of the first plan year to which section 411 applies.

(v) The excess of the accrued benefit payable at normal retirement age of any participant determined under section 411(b)(1) (A), (B), or (C) (without regard to section 411(b)(1)(D)), and paragraph (b)(1), (2), or (3) of this section (without regard to this paragraph) as of the day before the first day of the first plan year to which section 411 and this section applies over the accrued benefit determined under paragraph (c)(1) of this section shall be accrued in accordance with the provisions of the plan as in effect after the applicable effective date of section 411, as if the plan had been initially adopted on such effective date.

(d) Special rules—(1) First 2 years of service. Notwithstanding paragraphs (1), (2), and (3) of paragraph (b) of this section, under section 411(b)(1)(E) and this subparagraph, a plan shall not be treated as failing to satisfy the requirements of paragraph (b) of this section solely because the accrual of benefits under the plan does not become effective until the employee has completed 2 continuous years of service. For purposes of this subparagraph, continuous years of service are years of service (within the meaning of section 410(a)(3)(A)) which are not separated by a break in service (within the meaning of section 410(a)(5)). For years of service beginning after such 2 years of service, the accrued benefit of an employee shall not be less than that to which the employee would be entitled if section 411(b)(1)(E) and this subparagraph did not apply. Thus, for example, a plan which otherwise satisfies the requirements of paragraph (b)(2) of this section provides for a rate of accrual of 1 percent of average compensation for the highest 3 years of compensation beginning with the third year of service of a participant shall not be treated as satisfying paragraph (b)(2) of this section because as of the time the employee completes 3 continuous years of service there is no accrual during the first 2 years of service. In addition, a plan which otherwise satisfies the requirements of paragraph (b)(1) of this section and which requires that an employee must attain age 25 and complete 1 year of service prior to becoming a participant will not satisfy the requirements of paragraph (b)(1) of this section if an employee who completes 2 years of service prior to attaining age 25 does not begin accruals immediately upon commencement of participation in the plan. For rules relating to years of service, see 29 CFR part 2530, Department of Labor regulations relating to minimum standards for employee pension benefit plans.

(2) Certain insured defined benefit plans. Notwithstanding paragraphs (b) (1), (2), and (3) of this section, a defined benefit plan satisfies the requirements of paragraph (b) of this section if such plan is funded exclusively by the purchase of contracts from a life insurance company and such contracts satisfy the requirements of sections 412(i) (2) and (3) and the regulations thereunder. The preceding sentence is applicable only if an employee's accrued benefit as of any applicable date is not less than the cash surrender value such employee's insurance contracts would have on such applicable date if the requirements of section 412(i) (4), (5), and (6) and the regulations thereunder were satisfied.

(3) Accrued benefit may not decrease on account of increasing age or service. Notwithstanding paragraphs (b) (1), (2), and (3) of this section and paragraphs (d) (1) and (2) of this section, a defined benefit plan shall be treated as not satisfying the requirements of paragraphs (b) and (d) of this section if the participant's accrued benefit is reduced on account of any increase in his age or years of service. The preceding sentence shall not apply to social security supplements described in § 1.411(a)-7(c)(4).

(e) Separate accounting. A plan satisfies the requirements of this paragraph if the requirements of paragraph (e) (1) or (2) of this paragraph are met.

(1) Defined benefit plan. In the case of a defined benefit plan, the requirements of this paragraph are satisfied if the plan requires separate accounting for the portion of each employee's accrued benefit derived from any voluntary employee contributions permitted under the plan. For purposes of this subparagraph the term “voluntary employee contributions” means all employee contributions which are not mandatory contributions within the meaning of section 411(c)(2)(C) and the regulations thereunder. See § 1.411(c)-1(b)(1) for rules requiring the determination of such an accrued benefit by the use of a separate account.

(2) Defined contribution plan. In the case of a defined contribution plan, the requirements of this paragraph are not satisfied unless the plan requires separate accounting for each employee's accrued benefit. If a plan utilizes the break in service rule of section 411(a)(6)(C), an employee could have different percentages of vesting between pre-break and post-break accrued benefits. In such a case, the requirements of this paragraph are not satisfied unless the plan computes accrued benefits in a manner which takes into account different percentages. A plan which provides separate accounts for pre-break and post-break accrued benefits will be deemed to compute benefits in a reasonable manner.

(f) Year of participation—(1) In general. This paragraph is inapplicable to a defined contribution plan. For purposes of determining an employee's accrued benefit, a “year of participation” is a period of service determined under regulations prescribed by the Secretary of Labor in 29 CFR Part 2530, relating to minimum standards for employee pension benefit plans.

(2) Additional rule relating to year of participation. A trust shall not constitute a qualified trust if the plan of which such trust is a part provides for the crediting of a year of participation, or part thereof, and such credit results in the discrimination prohibited by section 401(a)(4).

(g) Additional illustrations. The application of this section may be illustrated by the following example:

(a) In general—(1) Organization of regulation. This section sets forth certain rules for determining whether a reduction occurs in the rate of benefit accrual under a defined benefit plan because of the attainment of any age for purposes of section 411(b)(1)(H)(i). Paragraph (b) of this section describes safe harbors for certain plan designs (including statutory hybrid plans) that are deemed to satisfy the age discrimination rules under section 411(b)(1)(H). Paragraph (c) of this section describes rules relating to statutory hybrid plan conversion amendments. Paragraph (d) of this section describes rules restricting interest credits (or equivalent amounts) under a statutory hybrid plan to a market rate of return. Paragraph (e) of this section contains additional rules related to market rates of return. Paragraph (f) of this section contains effective/applicability dates.

(2) Definitions. The definitions of accumulated benefit, lump sum-based benefit formula, statutory hybrid benefit formula, statutory hybrid plan, and variable annuity benefit formula in § 1.411(a)(13)-1(d) apply for purposes of this section.

(b) Safe harbors for certain plan designs—(1) Accumulated benefit testing—(i) In general. Pursuant to section 411(b)(5)(A), and subject to paragraph (b)(1)(ii) of this section, a plan is not treated as failing to meet the requirements of section 411(b)(1)(H)(i) with respect to an individual who is or could be a participant if, as of any date, the accumulated benefit of the individual would not be less than the accumulated benefit of any similarly situated, younger individual who is or could be a participant. Thus, this test involves a comparison of the accumulated benefit of an individual who is or could be a participant in the plan with the accumulated benefit of each similarly situated, younger individual who is or could be a participant in the plan. See paragraph (b)(5) of this section for rules regarding whether a younger individual who is or could be a participant is similarly situated to a participant. The comparison described in this paragraph (b)(1)(i) is based on any one of the following benefit measures, each of which is referred to as a safe-harbor formula measure:

(A) The annuity payable at normal retirement age (or current age, if later) if the accumulated benefit of the participant under the terms of the plan is an annuity payable at normal retirement age (or current age, if later).

(B) The current balance of a hypothetical account maintained for the participant if the accumulated benefit of the participant is the current balance of a hypothetical account.

(C) The current value of an accumulated percentage of the participant's final average compensation if the accumulated benefit of the participant is the current value of an accumulated percentage of the participant's final average compensation.

(ii) Benefit formulas for comparison—(A) In general. Except as provided in paragraphs (b)(1)(ii)(B), (C), (D) and (E) of this section, the safe harbor provided by section 411(b)(5)(A) and paragraph (b)(1)(i) of this section is available only with respect to a participant if the participant's accumulated benefit under the plan is expressed in terms of only one safe-harbor formula measure and no similarly situated, younger individual who is or could be a participant has an accumulated benefit that is expressed in terms of any measure other than that same safe-harbor formula measure. Thus, for example, if a plan provides that the accumulated benefit of participants who are age 55 or older is expressed under the terms of the plan as a life annuity payable at normal retirement age (or current age if later) as described in paragraph (b)(1)(i)(A) of this section and the plan provides that the accumulated benefit of participants who are younger than age 55 is expressed as the current balance of a hypothetical account as described in paragraph (b)(1)(i)(B) of this section, then the safe harbor described in section 411(b)(5)(A) and paragraph (b)(1)(i) of this section does not apply to individuals who are or could be participants and who are age 55 or older.

(B) Sum-of benefit formulas. If a plan provides that a participant's accumulated benefit is expressed as the sum of benefits determined in terms of two or more benefit formulas, each of which is expressed in terms of a different safe-harbor formula measure, then the plan is deemed to satisfy paragraph (b)(1)(i) of this section with respect to the participant, provided that the plan satisfies the comparison described in paragraph (b)(1)(i) of this section separately for benefits determined in terms of each safe-harbor formula measure and no accumulated benefit of a similarly situated, younger individual who is or could be a participant is expressed other than as—

(1) The sum of benefits under two or more benefit formulas, each of which is expressed in terms of one of those same safe-harbor formula measures as is used for the participant's “sum-of” benefit;

(2) The greater of benefits under two or more benefit formulas, each of which is expressed in terms of any one of those same safe-harbor formula measures;

(3) The choice of benefits under two or more benefit formulas, each of which is expressed in terms of any one of those same safe-harbor formula measures;

(4) A benefit that is determined in terms of only one of those same safe-harbor formula measures; or

(5) The lesser of benefits under two or more benefit formulas, at least one of which is expressed in terms of one of those same safe-harbor formula measures.

(C) Greater-of benefit formulas. If a plan provides that a participant's accumulated benefit is expressed as the greater of benefits under two or more benefit formulas, each of which is determined in terms of a different safe-harbor formula measure, then the plan is deemed to satisfy paragraph (b)(1)(i) of this section with respect to the participant, provided that the plan satisfies the comparison described in paragraph (b)(1)(i) of this section separately for benefits determined in terms of each safe-harbor formula measure and no accumulated benefit of a similarly situated, younger individual who is or could be a participant is expressed other than as—

(1) The greater of benefits determined under two or more benefit formulas, each of which is expressed in terms of one of those same safe-harbor formula measures as is used for the participant's “greater-of” benefit;

(2) The choice of benefits determined under two or more benefit formulas, each of which is expressed in terms of one of those same safe-harbor formula measures;

(3) A benefit that is determined in terms of only one of those same safe-harbor formula measures; or

(4) The lesser of benefits under two or more benefit formulas, at least one of which is expressed in terms of one of those same safe-harbor formula measures.

(D) Choice-of benefit formulas. If a plan provides that a participant's accumulated benefit is determined pursuant to a choice by the participant between benefits determined in terms of two or more different safe-harbor formula measures, then the plan is deemed to satisfy paragraph (b)(1)(i) of this section with respect to the participant, provided that the plan satisfies the comparison described in paragraph (b)(1)(i) of this section separately for benefits determined in terms of each safe-harbor formula measure and no accumulated benefit of a similarly situated, younger individual who is or could be a participant is expressed other than as—

(1) The choice of benefits determined under two or more benefit formulas, each of which is expressed in terms of one of those same safe-harbor formula measures as is used for the participant's “choice-of” benefit;

(2) A benefit that is determined in terms of only one of those same safe-harbor formula measures; or

(3) The lesser of benefits under two or more benefit formulas, at least one of which is expressed in terms of one of those same safe-harbor formula measures.

(E) Lesser-of benefit formulas. If a plan provides that a participant's accumulated benefit is expressed as a single safe-harbor formula measure and no accumulated benefit of a similarly situated, younger individual who is or could be a participant is expressed other than as a benefit that is determined under the same safe-harbor formula measure or as the lesser of benefits under two or more benefit formulas, at least one of which is expressed in terms of the same safe-harbor formula measure, then the plan is deemed to satisfy paragraph (b)(1)(i) of this section with respect to the participant only if the plan satisfies the comparison described in paragraph (b)(1)(i) of this section for benefits determined in terms of the same safe-harbor formula measure. Similarly, if a plan provides that a participant's accumulated benefit is expressed as the lesser of benefits under two or more benefit formulas, each of which is determined in terms of a different safe-harbor formula measure, then the plan is deemed to satisfy paragraph (b)(1)(i) of this section with respect to the participant only if the plan satisfies the comparison described in paragraph (b)(1)(i) of this section separately for benefits determined in terms of each safe-harbor formula measure and no accumulated benefit of a similarly situated, younger individual who is or could be a participant is expressed other than as the lesser of benefits under two or more benefit formulas, expressed in terms of all of those same safe-harbor formula measures (and any other additional formula measures).

(F) Limitations on plan formulas that provide for hypothetical accounts or accumulated percentages of final average compensation. For plan years described in paragraph (f)(2)(i)(B)(1) or (f)(2)(i)(B)(3) of this section (as applicable), a benefit measure is a safe harbor formula measure described in paragraph (b)(1)(i)(B) or (C) of this section only if the formula under which the balance of a hypothetical account or the accumulated percentage of final average compensation is determined is a lump-sum based benefit formula.

(iii) Disregard of certain subsidized benefits. For purposes of paragraph (b)(1)(i) of this section, any subsidized portion of an early retirement benefit that is included in a participant's accumulated benefit is disregarded. For this purpose, an early retirement benefit includes a subsidized portion only if it provides a higher actuarial present value on account of commencement before normal retirement age. However, for plan years described in paragraph (f)(2)(i)(B)(1) or (f)(2)(i)(B)(3) of this section (as applicable), if the annual benefit payable before normal retirement age is greater for a participant than the annual benefit under the corresponding form of benefit for any similarly situated, older individual who is or could be a participant and who is currently at or before normal retirement age, then that excess is not part of the subsidized portion of an early retirement benefit and, accordingly, is not disregarded under this paragraph (b)(1)(iii). For purposes of determining whether the annual benefit payable before normal retirement age is greater for a participant than the annual benefit under the corresponding form of benefit for any similarly situated, older individual who is or could be a participant, social security leveling options and social security supplements are disregarded. In addition, a plan is not treated as providing a greater annual benefit to a participant than to a similarly situated, older individual who is or could be a participant merely because the reduction (based on actuarial equivalence, using reasonable actuarial assumptions) in the amount of an annuity to reflect a survivor benefit is smaller for the participant than for a similarly situated, older individual who is or could be a participant.

(iv) Examples. The provisions of this paragraph (b)(1) are illustrated by the following examples:

(2) Indexed benefits— (i) In general. Except as provided in paragraph (b)(2)(iii) of this section, pursuant to section 411(b)(5)(E) and this paragraph (b)(2)(i), a defined benefit plan is not treated as failing to meet the requirements of section 411(b)(1)(H) with respect to a participant solely because a benefit formula (other than a lump sum-based benefit formula) under the plan provides for the periodic adjustment of the participant's accrued benefit under the plan by means of the application of a recognized index or methodology. An indexing rate that does not exceed a market rate of return, as defined in paragraph (d) of this section, is deemed to be a recognized index or methodology for purposes of the preceding sentence. In addition, for plan years described in paragraph (f)(2)(i)(B)(1) or (f)(2)(i)(B)(3) of this section, as applicable (or an earlier date as elected by the taxpayer), any subsidized portion of any early retirement benefit under such a plan that meets the requirements of paragraph (b)(1)(iii) is disregarded in determining whether the plan meets the requirements of section 411(b)(1)(H). However, such a plan must satisfy the qualification requirements otherwise applicable to statutory hybrid plans, including the requirements of § 1.411(a)(13)-1(c) (relating to minimum vesting standards) and paragraph (c) of this section (relating to plan conversion amendments) if the plan has an effect similar to a lump sum-based benefit formula, pursuant to the rules of § 1.411(a)(13)-1(d)(4)(ii).

(ii) Similarly situated participant test. Paragraph (b)(2)(i) of this section does not apply unless the aggregate adjustments made to a participant's accrued benefit under the plan (determined as a percentage of the unadjusted accrued benefit) in a period would not be less than the aggregate adjustments for any similarly situated, younger participant. This test requires a comparison, for each period, of the aggregate adjustments for each individual who is or could be a participant in the plan for the period with the aggregate adjustments of each other similarly situated, younger individual who is or could be a participant in the plan for that period. See paragraph (b)(5) of this section for rules regarding whether each younger individual who is or could be a participant is similarly situated to a participant.

(iii) Protection against loss—(A) In general. Paragraph (b)(2)(i) of this section does not apply unless the plan satisfies section 411(b)(5)(E)(ii) and paragraph (d)(2) of this section (relating to preservation of capital).

(B) Exception for variable annuity benefit formulas. The requirement to satisfy section 411(b)(5)(B)(i)(II), as set forth in paragraph (d)(2) of this section, as well as section 411(b)(5)(E)(ii), as set forth in this paragraph (b)(2)(iii), does not apply in the case of a benefit provided under a variable annuity benefit formula as defined in § 1.411(a)(13)-1(d)(6).

(3) Certain offsets permitted. A plan is not treated as failing to meet the requirements of section 411(b)(1)(H) solely because the plan provides offsets against benefits under the plan to the extent the offsets are allowable in applying the requirements of section 401(a) and the applicable requirements of the Employee Retirement Income Security Act of 1974, Public Law 93-406 (88 Stat. 829 (1974)), and the Age Discrimination in Employment Act of 1967, Public Law 90-202 (81 Stat. 602 (1967)).

(4) Permitted disparities in plan contributions or benefits. A plan is not treated as failing to meet the requirements of section 411(b)(1)(H) solely because the plan provides a disparity in contributions or benefits with respect to which the requirements of section 401(l) are met.

(5) Definition of similarly situated. For purposes of paragraphs (b)(1) and (b)(2) of this section, an individual is similarly situated to another individual if the individual is identical to that other individual in every respect that is relevant in determining a participant's benefit under the plan (including period of service, compensation, position, date of hire, work history, and any other respect) except for age. In determining whether an individual is similarly situated to another individual, any characteristic that is relevant for determining benefits under the plan and that is based directly or indirectly on age is disregarded. For example, if a particular benefit formula applies to a participant on account of the participant's age, an individual to whom the benefit formula does not apply and who is identical to the participant in all other respects is similarly situated to the participant. By contrast, an individual is not similarly situated to a participant if a different benefit formula applies to the individual and the application of the different formula is not based directly or indirectly on age.

(c) Special rules for plan conversion amendments—(1) In general. Pursuant to section 411(b)(5)(B)(ii), (iii), and (iv), if there is a conversion amendment within the meaning of paragraph (c)(4) of this section with respect to a defined benefit plan, then the plan is treated as failing to meet the requirements of section 411(b)(1)(H) unless the plan, after the amendment, satisfies the requirements of paragraph (c)(2) of this section.

(2) Separate calculation of post-conversion benefit—(i) In general. A statutory hybrid plan satisfies the requirements of this paragraph (c)(2) if the plan provides that, in the case of an individual who was a participant in the plan immediately before the date of adoption of the conversion amendment, the participant's benefit at any subsequent annuity starting date is not less than the sum of—

(A) The participant's section 411(d)(6) protected benefit (as defined in § 1.411(d)-3(g)(14)) with respect to service before the effective date of the conversion amendment, determined under the terms of the plan as in effect immediately before the effective date of the conversion amendment; and

(B) The participant's section 411(d)(6) protected benefit with respect to service on and after the effective date of the conversion amendment, determined under the terms of the plan as in effect after the effective date of the conversion amendment.

(ii) Rules of application. For purposes of this paragraph (c)(2), except as provided in paragraph (c)(3) of this section, the benefits under paragraphs (c)(2)(i)(A) and (c)(2)(i)(B) of this section must each be determined in the same manner as if they were provided under separate plans that are independent of each other (for example, without any benefit offsets), and, except to the extent permitted under § 1.411(d)-3 or § 1.411(d)-4 (or other applicable law), each optional form of payment provided under the terms of the plan with respect to a participant's section 411(d)(6) protected benefit as in effect before the conversion amendment must be available thereafter to the extent of the plan's benefits for service prior to the effective date of the conversion amendment.

(3) Establishment of opening hypothetical account balance or opening accumulated percentage—(i) Provided that the requirements of paragraph (c)(3)(ii) of this section are satisfied, a statutory hybrid plan under which an opening hypothetical account balance or opening accumulated percentage of the participant's final average compensation is established as of the effective date of the conversion amendment does not fail to satisfy the requirements of paragraph (c)(2) of this section merely because benefits attributable to that opening hypothetical account balance or opening accumulated percentage (that is, benefits that are not described in paragraph (c)(2)(i)(B) of this section) are substituted for benefits described in paragraph (c)(2)(i)(A) of this section.

(ii) Comparison of benefits at annuity starting date—(A) Testing requirement. The requirements of this paragraph (c)(3)(ii) are satisfied with respect to an optional form of benefit payable at an annuity starting date only if the plan provides that the amount of the benefit payable in that optional form under the lump sum-based benefit formula that is attributable to the opening hypothetical account balance or opening accumulated percentage as described in paragraph (c)(3)(i) of this section is not less than the benefit under the comparable optional form of benefit under paragraph (c)(2)(i)(A) of this section. To satisfy this requirement, if the benefit under the optional form attributable to the opening hypothetical account balance or opening accumulated percentage is less than the benefit under the comparable optional form of benefit described in paragraph (c)(2)(i)(A) of this section, then the benefit attributable to the opening hypothetical account balance or opening accumulated percentage must be increased to the extent necessary to provide the minimum benefit described in this paragraph (c)(3)(ii). Thus, if a plan is using the option under this paragraph (c)(3)(ii) to satisfy paragraph (c)(2) of this section with respect to a participant, the participant must receive a benefit equal to not less than the sum of—

(1) The benefit described in paragraph (c)(2)(i)(B) of this section; and

(2) The greater of—

(i) The benefit attributable to the opening hypothetical account balance or attributable to the opening accumulated percentage of the participant's final average compensation as described in this paragraph (c)(3)(ii); or

(ii) The benefit described in paragraph (c)(2)(i)(A) of this section.

(B) Comparable optional form of benefit. If there was an optional form of benefit within the same generalized optional form of benefit (within the meaning of § 1.411(d)-3(g)(8)) that would have been available to the participant at that annuity starting date under the terms of the plan as in effect immediately before the effective date of the conversion amendment, then that optional form of benefit is the comparable optional form of benefit.

(C) Special rule for new post-conversion optional forms of benefit. If an optional form of benefit is available on the annuity starting date with respect to the benefit attributable to the opening hypothetical account balance or opening accumulated percentage, but no optional form within the same generalized optional form of benefit (within the meaning of § 1.411(d)-3(g)(8)) was available at that annuity starting date under the terms of the plan as in effect immediately prior to the effective date of the conversion amendment, then, for purposes of this paragraph (c)(3)(ii), the plan is treated as if such an optional form of benefit were available immediately prior to the effective date of the conversion amendment for purposes of this paragraph (c)(3)(ii). Thus, for example, if a single-sum optional form of payment is not available under the plan terms applicable to the accrued benefit described in paragraph (c)(2)(i)(A) of this section, but a single-sum optional form of payment is available with respect to the benefit attributable to the opening hypothetical account balance or opening accumulated percentage as of the annuity starting date, then, for purposes of this paragraph (c)(3)(ii), the plan is treated as if a single sum (which satisfies the requirements of section 417(e)(3)) were available under the terms of the plan as in effect immediately prior to the effective date of the conversion amendment.

(4) Conversion amendment—(i) In general. An amendment is a conversion amendment that is subject to the requirements of this paragraph (c) with respect to a participant if—

(A) The amendment reduces or eliminates the benefits that, but for the amendment, the participant would have accrued after the effective date of the amendment under a benefit formula that is not a statutory hybrid benefit formula (and under which the participant was accruing benefits prior to the amendment); and

(B) After the effective date of the amendment, all or a portion of the participant's benefit accruals under the plan are determined under a statutory hybrid benefit formula.

(ii) Rules of application—(A) In general. Paragraphs (c)(4)(iii), (iv), and (v) of this section describe special rules that treat certain arrangements as conversion amendments. The rules described in those paragraphs apply both separately and in combination. Thus, for example, in an acquisition described in § 1.410(b)-2(f), if the buyer adopts an amendment under which a participant's benefits under the seller's plan that is not a statutory hybrid plan are coordinated with a separate plan of the buyer that is a statutory hybrid plan, such as through an offset of the participant's benefit under the buyer's plan by the participant's benefit under the seller's plan, the seller and buyer are treated as a single employer under paragraph (c)(4)(iv) of this section and they are treated as having adopted a conversion amendment under paragraph (c)(4)(iii) of this section. However, pursuant to paragraph (c)(4)(iii) of this section, if there is no coordination between the two plans, there is no conversion amendment.

(B) Covered amendments. Only amendments that eliminate or reduce accrued benefits described in section 411(a)(7), or a retirement-type subsidy described in section 411(d)(6)(B)(i), that would otherwise accrue as a result of future service are treated as amendments described in paragraph (c)(4)(i)(A) of this section.

(C) Operation of plan terms treated as covered amendment. If, under the terms of a plan, a change in the conditions of a participant's employment results in a reduction of the participant's benefits that would have accrued in the future under a benefit formula that is not a statutory hybrid benefit formula, the plan is treated for purposes of this paragraph (c)(4) as if such plan terms constitute an amendment that reduces the participant's benefits that would have accrued after the effective date of the change under a benefit formula that is not a statutory hybrid benefit formula. Thus, for example, if a participant transfers from an operating division that is covered by a non-statutory hybrid benefit formula to an operating division that is covered by a statutory hybrid benefit formula, there has been a conversion amendment and the effective date of the conversion amendment is the date of the transfer. For purposes of applying the effective date rule of paragraph (f)(1)(ii) of this section, the date that the relevant plan terms were adopted is treated as the adoption date of the amendment.

(iii) Multiple plans. An employer is treated as having adopted a conversion amendment if the employer adopts an amendment under which a participant's benefits under a plan that is not a statutory hybrid plan are coordinated with a separate plan that is a statutory hybrid plan, such as through a reduction (offset) of the benefit under the plan that is not a statutory hybrid plan.

(iv) Multiple employers. If the employer of an employee changes as a result of a transaction described in § 1.410(b)-2(f), then the two employers are treated as a single employer for purposes of this paragraph (c)(4).

(v) Multiple amendments—(A) In general—(1) General rule. For purposes of this paragraph (c)(4), a conversion amendment includes multiple amendments that result in a conversion amendment even if the amendments are not conversion amendments individually. For example, an employer is treated as having adopted a conversion amendment if the employer first adopts an amendment described in paragraph (c)(4)(i)(A) of this section and, at a later date, adopts an amendment that adds a benefit under a statutory hybrid benefit formula as described in paragraph (c)(4)(i)(B) of this section, if they are consolidated under paragraph (c)(4)(v)(A)(2) of this section.

(2) Delay between plan amendments. In determining whether a conversion amendment has been adopted, an amendment to provide a benefit under a statutory hybrid benefit formula is consolidated with a prior amendment to reduce non-statutory hybrid benefit formula benefits if the amendment providing benefits under a statutory hybrid benefit formula is adopted within three years after adoption of the amendment reducing non-statutory hybrid benefit formula benefits. Thus, the later adoption of the statutory hybrid benefit formula will cause the earlier amendment to be treated as part of a conversion amendment. In the case of an amendment to provide a benefit under a statutory hybrid benefit formula that is adopted more than three years after adoption of an amendment to reduce benefits under a non-statutory hybrid benefit formula, there is a presumption that the amendments are not consolidated unless the facts and circumstances indicate that adoption of the amendment to provide a benefit under a statutory hybrid benefit formula was intended at the time of reduction in the non-statutory hybrid benefit formula.

(B) Multiple conversion amendments. If an employer adopts multiple amendments reducing benefits described in paragraph (c)(4)(i)(A) of this section, each amendment is treated as a separate conversion amendment, provided that paragraph (c)(4)(i)(B) of this section is applicable at the time of the amendment (taking into account the rules of this paragraph (c)(4)).

(vi) Effective date of a conversion amendment. The effective date of a conversion amendment is, with respect to a participant, the date as of which the reduction of the participant's benefits described in paragraph (c)(4)(i)(A) of this section occurs. In accordance with section 411(d)(6), the date of a reduction of those benefits cannot be earlier than the date of adoption of the conversion amendment.

(5) Examples. The following examples illustrate the application of this paragraph (c):

(d) Market rate of return—(1) In general—(i) Basic test. Subject to the rules of paragraph (e) of this section, a statutory hybrid plan satisfies the requirements of section 411(b)(1)(H) and this paragraph (d) only if, for any plan year, the interest crediting rate with respect to benefits determined under a statutory hybrid benefit formula is not greater than a market rate of return.

(ii) Definitions relating to market rate of return—(A) Interest credit. Subject to other rules in this paragraph (d), an interest credit for purposes of this paragraph (d) and section 411(b)(5)(B) means the following adjustments to a participant's accumulated benefit under a statutory hybrid benefit formula, to the extent not conditioned on current service and not made on account of imputed service (as defined in § 1.401(a)(4)-11(d)(3)(ii)(B))—

(1) Any increase or decrease for a period, under the terms of the plan at the beginning of the period, that is calculated by applying a rate of interest or rate of return (including a rate of increase or decrease under an index) to the participant's accumulated benefit (or a portion thereof) as of the beginning of the period; and

(2) Any other increase for a period, under the terms of the plan at the beginning of the period.

(B) Treatment of plan amendments. An increase to a participant's accumulated benefit is not treated as an interest credit to the extent the increase is made as a result of a plan amendment providing for a one-time adjustment to the participant's accumulated benefit. However, a pattern of repeated plan amendments each of which provides for a one-time adjustment to a participant's accumulated benefit will cause such adjustments to be treated as provided on a permanent basis under the terms of the plan. See § 1.411(d)-4, A-1(c)(1).

(C) Interest crediting rate. Except as otherwise provided in this paragraph (d), the interest crediting rate, or effective rate of return, for a period with respect to a participant equals the total amount of interest credits for the period divided by the participant's accumulated benefit at the beginning of the period.

(D) Principal credit. For purposes of this paragraph (d), a principal credit means any increase to a participant's accumulated benefit under a statutory hybrid benefit formula that is not an interest credit. Thus, for example, a principal credit includes an increase to a participant's accumulated benefit to the extent the increase is conditioned on current service or made on account of imputed service. As a result, a principal credit includes an increase to the value of an accumulated percentage of the participant's final average compensation. For indexed benefits described in paragraph (b)(2) of this section, a principal credit includes an increase to the participant's accrued benefit other than an increase provided by indexing. In addition, pursuant to the rule in paragraph (d)(1)(ii)(B) of this section, a principal credit generally includes an increase to a participant's accumulated benefit to the extent the increase is made as a result of a plan amendment providing for a one-time adjustment to the participant's accumulated benefit. As a result, a principal credit includes an opening hypothetical account balance or opening accumulated percentage of the participant's final average compensation, as described in paragraph (c)(3) of this section.

(iii) Market rate of return for single rates. Except as otherwise provided in this paragraph (d)(1), an interest crediting rate is not in excess of a market rate of return only if the plan terms provide that the interest credit for each plan year is determined using one of the following specified interest crediting rates:

(A) The interest rate on long-term investment grade corporate bonds (as described in paragraph (d)(3) of this section).

(B) An interest rate that, under paragraph (d)(4) of this section, is deemed to be not in excess of the interest rate described in paragraph (d)(3) of this section.

(C) A rate of return that, under paragraph (d)(5) of this section, is not in excess of a market rate of return.

(iv) Timing and other rules related to interest crediting rate—(A) In general. A plan that provides interest credits must specify how the plan determines interest credits and must specify how and when interest credits are credited. The plan must specify the method for determining interest credits in accordance with the requirements of paragraph (d)(1)(iv)(B) of this section, the frequency of interest crediting in accordance with the requirements of paragraph (d)(1)(iv)(C) of this section, and the treatment of interest credits on distributed amounts, as well as other debits and credits during the period, in accordance with the rules of paragraph (d)(1)(iv)(D) of this section. In addition, a plan is permitted to round the calculated interest rate or rate of return in accordance with paragraph (d)(1)(iv)(E) of this section. See paragraph (e) of this section for additional rules that apply to changes in the interest crediting rate.

(B) Methods to determine interest credits. A plan that is using any specified interest crediting rate can determine interest credits for each current interest crediting period based on the effective periodic interest crediting rate that applies over the period. Alternatively, a plan that is using one of the interest crediting rates described in paragraph (d)(3) or (d)(4) of this section can determine interest credits for a stability period based on the interest crediting rate for a specified lookback month with respect to that stability period. For purposes of the preceding sentence, the stability period and lookback month must satisfy the rules for selecting the stability period and lookback month under § 1.417(e)-1(d)(4), although the interest crediting rate can be any one of the rates in paragraph (d)(3) or (d)(4) of this section and the stability period and lookback month need not be the same as those used under the plan for purposes of section 417(e)(3).

(C) Frequency of interest crediting. Interest credits under a plan must be provided on an annual or more frequent periodic basis and interest credits for each interest crediting period must be credited as of the end of the period. If a plan provides for the crediting of interest more frequently than annually (for example, daily, monthly or quarterly) based on one of the annual interest rates described in paragraph (d)(3) or (d)(4) of this section, then the plan generally provides an above market rate of return unless each periodic interest credit is determined using an interest crediting rate that is no greater than a pro rata portion of the applicable annual interest crediting rate. However, a plan that credits interest daily based on one of the annual interest rates described in paragraph (d)(3) or (d)(4) of this section is not treated as providing an above market rate of return merely because the plan determines each daily interest credit using a daily interest crediting rate that is 1/360 of the applicable annual interest crediting rate. In addition, interest credits determined, under the terms of a plan, based on one of the annual interest rates described in paragraph (d)(3) or (d)(4) of this section are not treated as creating an effective rate of return that is in excess of a market rate of return merely because an otherwise permissible interest crediting rate for a plan year is compounded more frequently than annually. Thus, for example, if a plan's terms provide for interest to be credited monthly and for the interest crediting rate to be equal to the interest rate on long-term investment grade corporate bonds (as described in paragraph (d)(3) of this section) and the applicable annual rate on these bonds for the plan year is 6 percent, then the accumulated benefit at the beginning of each month could be increased as a result of interest credits by as much as 0.5 percent per month during the plan year without resulting in an interest crediting rate that is in excess of a market rate of return.

(D) Debits and credits during the interest crediting period. A plan is not treated as failing to meet the requirements of this paragraph (d) merely because the plan does not provide for interest credits on amounts distributed prior to the end of the interest crediting period. Furthermore, a plan is not treated as failing to meet the requirements of this paragraph (d) merely because the plan calculates increases or decreases to the participant's accumulated benefit by applying a rate of interest or rate of return (including a rate of increase or decrease under an index) to the participant's adjusted accumulated benefit (or portion thereof) for the period. For this purpose, the participant's adjusted accumulated benefit equals the participant's accumulated benefit as of the beginning of the period, adjusted for debits and credits (other than interest credits) made to the accumulated benefit prior to the end of the interest crediting period, with appropriate weighting for those debits and credits based on their timing within the period. For plans that calculate increases or decreases to the participant's accumulated benefit by applying a rate of interest or rate of return to the participant's adjusted accumulated benefit (or portion thereof) for the period, interest credits include these increases and decreases, to the extent provided under the terms of the plan at the beginning of the period and to the extent not conditioned on current service and not made on account of imputed service (as defined in § 1.401(a)(4)-11(d)(3)(ii)(B)), and the interest crediting rate with respect to a participant equals the total amount of interest credits for the period divided by the participant's adjusted accumulated benefit for the period.

(E) Rounding of interest crediting rate. A plan is not treated as failing to meet the requirements of this paragraph (d) merely because the plan determines interest credits for an interest crediting period by rounding the calculated interest rate or rate of return in accordance with this paragraph (d)(1)(iv)(E). An annual rate may be rounded to the nearest multiple of 25 basis points (or a smaller rounding interval). If a plan provides for the crediting of interest more frequently than annually, then the rounding interval must not exceed a pro-rata portion of 25 basis points. Notwithstanding the preceding sentence, a plan is permitted to round to the nearest basis point regardless of the length of the interest crediting period.

(v) Lesser rates. An interest crediting rate is not in excess of a market rate of return if the rate can never be in excess of a particular rate that is described in paragraph (d)(1)(iii) of this section. Thus, for example, an interest crediting rate that always equals the rate described in paragraph (d)(3) of this section minus 200 basis points is not in excess of a market rate of return because it can never be in excess of the rate described in paragraph (d)(3) of this section. Similarly, an interest crediting rate that always equals the lesser of the yield on 30-year Treasury Constant Maturities and a fixed 7 percent interest rate is not in excess of a market rate of return because it can never be in excess of the yield on 30-year Treasury Constant Maturities.

(vi) Greater-of rates. If a statutory hybrid plan determines an interest credit by applying the greater of 2 or more different rates to the accumulated benefit, the effective interest crediting rate is not in excess of a market rate of return only if each of the different rates would separately satisfy the requirements of this paragraph (d) and the requirements of paragraph (d)(6) of this section are also satisfied.

(vii) Blended rates. A statutory hybrid plan does not provide an effective interest crediting rate that is in excess of a market rate of return merely because the plan determines an interest credit by applying different rates to different predetermined portions of the accumulated benefit, provided each rate would separately satisfy the requirements of this paragraph (d) if the rate applied to the entire accumulated benefit.

(viii) Increases to existing rates and addition of other rates—(A) Increases to existing rates. The Commissioner may, in guidance published in the Internal Revenue Bulletin, see § 601.601(d)(2)(ii)(b) of this chapter, increase an interest crediting rate set forth in this paragraph (d), so that the increased rate is treated as satisfying the requirement that the rate not exceed a market rate of return for purposes of this paragraph (d) and section 411(b)(5)(B). For this purpose, these increases can include increases to the maximum permitted margin that can be added to one or more of the safe harbor rates set forth in paragraph (d)(4) of this section, increases to the maximum permitted fixed rate set forth in paragraph (d)(4)(v) of this section, or increases to a maximum permitted annual floor set forth in paragraph (d)(6) of this section.

(B) Additional rates. The Commissioner may, in guidance published in the Internal Revenue Bulletin, see § 601.601(d)(2)(ii)(b) of this chapter, provide for additional interest crediting rates that satisfy the requirement that they not exceed a market rate of return for purposes of this paragraph (d) and section 411(b)(5)(B) (including providing for additional combinations of rates, such as annual minimums in conjunction with rates that are based on rates described in paragraph (d)(5) of this section but that are reduced in order to ensure that the effective rate of return does not exceed a market rate of return).

(2) Preservation of capital requirement—(i) General rule. A statutory hybrid plan satisfies the requirements of section 411(b)(1)(H) only if the plan provides that the participant's benefit under the statutory hybrid benefit formula determined as of the participant's annuity starting date is no less than the benefit determined as if the accumulated benefit were equal to the sum of all principal credits (as described in paragraph (d)(1)(ii)(D) of this section) credited under the plan to the participant as of that date (including principal credits that were credited before the applicable statutory effective date of paragraph (f)(1) of this section). This paragraph (d)(2) applies only as of an annuity starting date, within the meaning of § 1.401(a)-20, A-10(b), with respect to which a distribution of the participant's entire vested benefit under the plan's statutory hybrid benefit formula as of that date commences. For a participant who has more than one annuity starting date, paragraph (d)(2)(ii) of this section provides rules to account for prior annuity starting dates when applying this paragraph (d)(2)(i).

(ii) Application to multiple annuity starting dates—(A) In general. If the comparison under paragraph (d)(2)(ii)(B) of this section results in the sum of all principal credits credited to the participant (as of the current annuity starting date) exceeding the sum of the amounts described in paragraphs (d)(2)(ii)(B)(1) through (d)(2)(ii)(B)(3) of this section, then the participant's benefit to be distributed at the current annuity starting date must be no less than would be provided if that excess were included in the current accumulated benefit.

(B) Comparison to reflect prior distributions. For a participant who has more than one annuity starting date, the sum of all principal credits credited to the participant under the plan, as of the current annuity starting date, is compared to the sum of—

(1) The remaining balance of the participant's accumulated benefit as of the current annuity starting date;

(2) The amount of the reduction to the participant's accumulated benefit under the statutory hybrid benefit formula that is attributable to any prior distribution of the participant's benefit under that formula; and

(3) Any amount that was treated as included in the accumulated benefit under the rules of this paragraph (d)(2) as of any prior annuity starting date.

(C) Special rule for participants with 5 or more breaks in service. A plan is permitted to provide that, in the case of a participant who receives a distribution of the entire vested benefit under the plan and thereafter completes 5 consecutive 1-year breaks in service, as defined in section 411(a)(6)(A), the rules of this paragraph (d)(2) are applied without regard to the prior period of service. Thus, in the case of such a participant, the plan is permitted to provide that the rules of this paragraph (d)(2) are applied disregarding the principal credits and distributions that occurred before the breaks in service.

(iii) Exception for variable annuity benefit formulas. See paragraph (b)(2)(iii)(B) of this section for an exception to this paragraph (d)(2).

(3) Long-term investment grade corporate bonds. For purposes of this paragraph (d), the rate of interest on long-term investment grade corporate bonds means the third segment rate described in section 417(e)(3)(D) or 430(h)(2)(C)(iii) (determined with or without regard to section 430(h)(2)(C)(iv) and with or without regard to the transition rules of section 417(e)(3)(D)(ii) or 430(h)(2)(G)). However, for plan years beginning prior to January 1, 2008, the rate of interest on long-term investment grade corporate bonds means the rate described in section 412(b)(5)(B)(ii)(II) prior to amendment by the Pension Protection Act of 2006, Public Law 109-280 (120 Stat. 780 (2006)) (PPA '06).

(4) Safe harbor rates of interest—(i) In general. This paragraph (d)(4) identifies interest rates that are deemed to be not in excess of the interest rate described in paragraph (d)(3) of this section. The Commissioner may, in guidance of general applicability, specify additional interest crediting rates that are deemed to be not in excess of the rate described in paragraph (d)(3) of this section. See § 601.601(d)(2)(ii)(b).

(ii) Rates based on government bonds with margins. An interest crediting rate is deemed to be not in excess of the interest rate described in paragraph (d)(3) of this section if the rate is equal to the sum of any of the following rates of interest for bonds and the associated margin for that interest rate:

(iii) Eligible cost-of-living indices. An interest crediting rate is deemed to be not in excess of the interest rate described in paragraph (d)(3) of this section if the rate is adjusted no less frequently than annually and is equal to the rate of increase with respect to an eligible cost-of-living index described in § 1.401(a)(9)-6(o)(2), except that, for purposes of this paragraph (d)(4)(iii), the eligible cost-of-living index described in § 1.401(a)(9)-6(o)(2)(ii) is increased by 300 basis points.

(iv) Short and mid-term investment grade corporate bonds. An interest crediting rate equal to the first segment rate is deemed to be not in excess of the interest rate described in paragraph (d)(3) of this section. Similarly, an interest crediting rate equal to the second segment rate is deemed to be not in excess of the interest rate described in paragraph (d)(3) of this section. For this purpose, the first and second segment rates mean the first and second segment rates described in section 417(e)(3)(D) or 430(h)(2)(C), determined with or without regard to section 430(h)(2)(C)(iv) and with or without regard to the transition rules of section 417(e)(3)(D)(ii) or 430(h)(2)(G).

(v) Fixed rate of interest. An annual interest crediting rate equal to a fixed 6 percent is deemed to be not in excess of the interest rate described in paragraph (d)(3) of this section.

(5) Other rates of return—(i) General rule. This paragraph (d)(5) sets forth additional methods for determining an interest crediting rate that is not in excess of a market rate of return.

(ii) Actual rate of return on plan assets—(A) In general. An interest crediting rate equal to the actual rate of return on the aggregate assets of the plan, including both positive returns and negative returns, is not in excess of a market rate of return if the plan's assets are diversified so as to minimize the volatility of returns. This requirement that plan assets be diversified so as to minimize the volatility of returns does not require greater diversification than is required under section 404(a)(1)(C) of Title I of the Employee Retirement Income Security Act of 1974, Public Law 93-406 (88 Stat. 829 (1974)), as amended (ERISA), with respect to defined benefit pension plans.

(B) Subset of plan assets. An interest crediting rate equal to the actual rate of return on the assets within a specified subset of plan assets, including both positive and negative returns, is not in excess of a market rate of return if—

(1) The subset of plan assets is diversified so as to minimize the volatility of returns, within the meaning of paragraph (d)(5)(ii)(A) of this section (thus, this requirement is satisfied if the subset of plan assets is diversified such that it would meet the requirements of paragraph (d)(5)(ii)(A) of this section if the subset were aggregate plan assets);

(2) The aggregate fair market value of qualifying employer securities and qualifying employer real property (within the meaning of section 407 of ERISA) held in the subset of plan assets does not exceed 10 percent of the fair market value of the aggregate assets in the subset; and

(3) The fair market value of the assets within the subset of plan assets approximates the liabilities for benefits that are adjusted by reference to the rate of return on the assets within the subset, determined using reasonable actuarial assumptions.

(C) Examples. The following examples illustrate the application of paragraph (d)(5)(ii)(B) of this section:

(iii) Annuity contract rates. The rate of return on the annuity contract for the employee issued by an insurance company licensed under the laws of a State is not in excess of a market rate of return. However, this paragraph (d)(5)(iii) does not apply if the Commissioner determines that the annuity contract has been structured to provide an interest crediting rate that is in excess of a market rate of return.

(iv) Rate of return on certain RICs. An interest crediting rate is not in excess of a market rate of return if it is equal to the rate of return on a regulated investment company (RIC), as defined in section 851, that is reasonably expected to be not significantly more volatile than the broad United States equities market or a similarly broad international equities market. For example, a RIC that has most of its assets invested in securities of issuers (including other RICs) concentrated in an industry sector or a country other than the United States generally would not meet this requirement. Likewise a RIC that uses leverage, or that has significant investment in derivative financial products, for the purpose of achieving returns that amplify the returns of an unleveraged investment, generally would not meet this requirement. Thus, a RIC that has most of its investments concentrated in the semiconductor industry or that uses leverage in order to provide a rate of return that is twice the rate of return on the Standard & Poor's 500 index (S&P 500) would not meet this requirement. On the other hand, a RIC with investments that track the rate of return on the S&P 500, a broad-based “small-cap” index (such as the Russell 2000 index), or a broad-based international equities index would meet this requirement.

(6) Combinations of rates of return—(i) In general. A plan that determines interest credits based, in whole or in part, on the greater of two or more different interest crediting rates provides an effective interest crediting rate in excess of a market rate of return unless the combination of rates is described in paragraph (d)(6)(ii), (d)(6)(iii), (e)(3)(iii), or (e)(4) of this section. However, a plan is not treated as providing the greater of two or more interest crediting rates merely because the plan satisfies the requirements of paragraph (d)(2) of this section. In addition, a plan is not treated as providing the greater of two or more interest crediting rates merely because a rate of return described in paragraph (d)(5)(iii) of this section is itself based on the greater of two or more rates.

(ii) Annual or more frequent floor—(A) Application to segment rates. An interest crediting rate under a plan does not fail to be described in paragraph (d)(3) or (d)(4)(iv) of this section for an interest crediting period merely because the plan provides that the interest crediting rate for that interest crediting period equals the greater of—

(1) An interest crediting rate described in paragraph (d)(3) or (d)(4)(iv) of this section; and

(2) An annual interest rate of 4 percent or less (or a pro rata portion of an annual interest rate of 4 percent or less for plans that provide interest credits more frequently than annually).

(B) Application to other bond-based rates. An interest crediting rate under a plan does not fail to be described in paragraph (d)(4) of this section for an interest crediting period merely because the plan provides that the interest crediting rate for that interest crediting period equals the greater of—

(1) An interest crediting rate described in paragraph (d)(4)(ii) or (d)(4)(iii) of this section; and

(2) An annual interest rate of 5 percent or less (or a pro rata portion of an annual interest rate of 5 percent or less for plans that provide interest credits more frequently than annually).

(iii) Cumulative floor applied to investment-based or bond-based rates—(A) In general. A plan that determines interest credits under a statutory hybrid benefit formula using a particular interest crediting rate described in paragraph (d)(3), (d)(4), or (d)(5) of this section (or an interest crediting rate that can never be in excess of a particular interest crediting rate described in paragraph (d)(3), (d)(4) or (d)(5) of this section) does not provide an effective interest crediting rate in excess of a market rate of return merely because the plan provides that the participant's benefit under the statutory hybrid benefit formula determined as of the participant's annuity starting date is equal to the benefit determined as if the accumulated benefit were equal to the greater of—

(1) The accumulated benefit determined using the interest crediting rate; and

(2) The accumulated benefit determined as if the plan had used a fixed annual interest crediting rate equal to 3 percent (or a lower rate) for all principal credits that are credited under the plan to the participant during the guarantee period (minimum guarantee amount).

(B) Guarantee period defined. The guarantee period is the prospective period that begins on the date the cumulative floor described in this paragraph (d)(6)(iii) begins to apply to the participant's benefit and that ends on the date on which that cumulative floor ceases to apply to the participant's benefit.

(C) Application to multiple annuity starting dates. The determination under this paragraph (d)(6)(iii) is made only as of an annuity starting date, within the meaning of § 1.401(a)-20, A-10(b), with respect to which a distribution of the participant's entire vested benefit under the plan's statutory hybrid benefit formula as of that date commences. For a participant who has more than one annuity starting date, paragraph (d)(6)(iii)(D) of this section provides rules to account for prior annuity starting dates when applying paragraph (d)(6)(iii)(A) of this section. If the comparison under paragraph (d)(6)(iii)(D) of this section results in the minimum guarantee amount exceeding the sum of the amounts described in paragraphs (d)(6)(iii)(D)(1) through (d)(6)(iii)(D)(3) of this section, then the participant's benefit to be distributed at the current annuity starting date must be no less than would be provided if that excess were included in the current accumulated benefit.

(D) Comparison to reflect prior distributions. For a participant who has more than one annuity starting date, the minimum guarantee amount (described in paragraph (d)(6)(iii)(A)(2) of this section), as of the current annuity starting date, is compared to the sum of—

(1) The remaining balance of the participant's accumulated benefit, as of the current annuity starting date, to which a minimum guaranteed rate described in paragraph (d)(6)(iii)(A)(2) of this section applies;

(2) The amount of the reduction to the participant's accumulated benefit under the statutory hybrid benefit formula that is attributable to any prior distribution of the participant's benefit under that formula and to which a minimum guaranteed rate described in paragraph (d)(6)(iii)(A)(2) of this section applied, together with interest at that minimum guaranteed rate annually from the prior annuity starting date to the current annuity starting date; and

(3) Any amount that was treated as included in the accumulated benefit under the rules of this paragraph (d)(6)(iii) as of any prior annuity starting date, together with interest annually at the minimum guaranteed rate that applied to the prior distribution from the prior annuity starting date to the current annuity starting date.

(E) Application to portion of participant's benefit. A cumulative floor described in this paragraph (d)(6)(iii) may be applied to a portion of a participant's benefit, provided the requirements of this paragraph (d)(6)(iii) are satisfied with respect to that portion of the benefit. If a cumulative floor described in this paragraph (d)(6)(iii) applies to a portion of a participant's benefit, only the principal credits that are attributable to that portion of the participant's benefit are taken into account in determining the amount of the guarantee described in paragraph (d)(6)(iii)(A)(2) of this section.

(e) Other rules regarding market rates of return—(1) In general. This paragraph (e) sets forth additional rules regarding the application of the market rate of return requirement with respect to benefits determined under a statutory hybrid benefit formula.

(2) Plan termination—(i) In general. This paragraph (e)(2) provides special rules that apply for purposes of determining certain plan factors under a statutory hybrid benefit formula after the plan termination date of a statutory hybrid plan. The terms of a statutory hybrid plan must reflect the requirements of this paragraph (e)(2). Paragraph (e)(2)(ii) of this section sets forth rules relating to the interest crediting rate for interest crediting periods that end after the plan termination date. Paragraph (e)(2)(iii) of this section sets forth rules for converting a participant's accumulated benefit to an annuity after the plan termination date. Paragraph (e)(2)(iv) of this section sets forth rules of application. Paragraph (e)(2)(v) of this section contains examples. The Commissioner may, in revenue rulings, notices, or other guidance published in the Internal Revenue Bulletin, provide for additional rules that apply for purposes of this paragraph (e)(2) and the plan termination provisions of section 411(b)(5)(B)(vi). See § 601.601(d)(2)(ii)(b) of this chapter. See also regulations of the Pension Benefit Guaranty Corporation for additional rules that apply when a pension plan subject to Title IV of ERISA is terminated.

(ii) Interest crediting rates used to determine accumulated benefits—(A) General rule. The interest crediting rate used under the plan to determine a participant's accumulated benefit for interest crediting periods that end after the plan termination date must be equal to the average of the interest rates used under the plan during the 5-year period ending on the plan termination date. Except as otherwise provided in this paragraph (e)(2)(ii), the actual annual interest rate (taking into account minimums, maximums, and other adjustments) used to determine interest credits under the plan for each of the interest crediting periods is used for purposes of determining the average of the interest rates.

(B) Special rule for variable interest crediting rates that are other rates of return—(1) Application to interest crediting periods. This paragraph (e)(2)(ii)(B) applies for an interest crediting period if the interest crediting rate that was used for that interest crediting period was a rate of return described in paragraph (d)(5) of this section. This paragraph (e)(2)(ii)(B) also applies for an interest crediting period that begins before the first plan year described in paragraph (f)(2)(i)(B)(1) or (f)(2)(i)(B)(3) of this section (as applicable), if the interest crediting rate that was used for that interest crediting period had the potential to be negative. For this purpose, a rate is not treated as having the potential to be negative if it is a rate described in paragraph (d)(3) or (d)(4) of this section or is any other rate that is based solely on current bond yields.

(2) Use of substitution rate. For any interest crediting period to which this paragraph (e)(2)(ii)(B) applies, for purposes of determining the average of the interest rates under this paragraph (e)(2)(ii), the interest rate used under the plan for the interest crediting period is deemed to be equal to the substitution rate (as described in paragraph (e)(2)(ii)(C) of this section) for the period.

(C) Definition of substitution rate. The substitution rate for any interest crediting period equals the second segment rate under section 430(h)(2)(C)(ii) (determined without regard to section 430(h)(2)(C)(iv)) for the last calendar month ending before the beginning of the interest crediting period, as adjusted to account for any minimums or maximums that applied in the period (other than cumulative floors under paragraph (d)(6)(iii) of this section), but without regard to other reductions that applied in the period. Thus, for example, if the actual interest crediting rate in an interest crediting period is equal to the rate of return on plan assets, but not greater than 5 percent, then the substitution rate for that interest crediting period is equal to the lesser of the applicable second segment rate for the period and 5 percent. However, if the actual interest crediting rate for an interest crediting period is equal to the rate of return on plan assets minus 200 basis points, then the substitution rate for that interest crediting period is equal to the applicable second segment rate for the period.

(D) Cumulative floors. Cumulative floors under paragraph (d)(6)(iii) of this section that applied during the 5-year period ending on the plan termination date are not taken into account for purposes of determining the average of the interest rates under this paragraph (e)(2)(ii). However, the rules of paragraph (d)(6)(iii) of this section continue to apply to determine benefits as of annuity starting dates on or after the plan termination date. Thus, if, as of an annuity starting date on or after the plan termination date, the benefit provided by applying an applicable cumulative minimum rate under paragraph (d)(6)(iii)(A)(2) of this section exceeds the benefit determined by applying interest credits to the participant's accumulated benefit (with interest credits for interest crediting periods that end after the plan termination date determined under this paragraph (e)(2)), then that cumulative minimum rate is used to determine benefits as of that annuity starting date.

(iii) Annuity conversion rates and factors—(A) Conversion factors where a separate mortality table was used prior to plan termination—(1) Use of a separate mortality table. This paragraph (e)(2)(iii)(A) applies for purposes of converting a participant's accumulated benefit to an annuity after the plan termination date if, for the entire 5-year period ending on the plan termination date, the plan provides for a mortality table in conjunction with an interest rate to be used to convert a participant's accumulated benefit (or a portion thereof) to an annuity. If this paragraph (e)(2)(iii)(A) applies, then the plan is treated as meeting the requirements of section 411(b)(5)(B)(i) and paragraph (d)(1) of this section only if, for purposes of converting a participant's accumulated benefit (or portion thereof) to an annuity for annuity starting dates after the plan termination date, the mortality table used is the table described in paragraph (e)(2)(iii)(A)(2) of this section and the interest rate is the rate described in paragraph (e)(2)(iii)(A)(3) of this section.

(2) Specific mortality table. The mortality table used is the mortality table specified under the plan for purposes of converting a participant's accumulated benefit to an annuity as of the termination date. This mortality table is used regardless of whether it was used during the entire 5-year period ending on the plan termination date. For purposes of applying this paragraph (e)(2)(iii)(A)(2), if the mortality table specified in the plan, as of the plan termination date, is a mortality table that is updated to reflect expected improvements in mortality experience (such as occurs with the applicable mortality table under section 417(e)(3)), then the table used for an annuity starting date after the plan termination date takes into account updates through the annuity starting date.

(3) Specific interest rate. The interest rate used is the interest rate specified under the plan for purposes of converting a participant's accumulated benefit to an annuity for annuity starting dates after the plan termination date. However, if the interest rate used under the plan for purposes of converting a participant's accumulated benefit to an annuity has not been the same fixed rate during the 5-year period ending on the plan termination date, then the interest rate used for purposes of converting a participant's accumulated benefit to an annuity for annuity starting dates after the plan termination date is the average interest rate that applied for this purpose during the 5-year period ending on the plan termination date.

(B) Tabular factors. If, as of the plan termination date, a tabular annuity conversion factor (i.e., a single conversion factor that combines the effect of interest and mortality) is used to convert a participant's accumulated benefit (or a portion thereof) to an annuity and that same fixed tabular annuity conversion factor has been used during the entire 5-year period ending on the plan termination date, then the plan satisfies the requirements of this paragraph (e)(2)(iii) only if that same tabular annuity conversion factor continues to apply after the plan termination date. However, if the tabular annuity conversion factor used to convert a participant's accumulated benefit (or a portion thereof) to an annuity is not described in the preceding sentence (including any case in which the tabular annuity conversion factor was a fixed conversion factor that changed during the 5-year period ending on the plan termination date), then the plan satisfies the requirements of this paragraph (e)(2)(iii) only if the tabular annuity conversion factor used to convert a participant's accumulated benefit (or a portion thereof) to an annuity for annuity starting dates after the plan termination date is equal to the average of the tabular annuity conversion factors used under the plan for that purpose during the 5-year period ending on the plan termination date.

(C) Factor applicable where a separate mortality table was not used for entire 5-year period prior to plan termination. If paragraph (e)(2)(iii)(A) of this section does not apply (including any case in which a separate mortality table was used in conjunction with a separate interest rate to convert a participant's accumulated benefit (or a portion thereof) to an annuity for only a portion of the 5-year period ending on the plan termination date), then the plan is treated as having used a tabular annuity conversion factor to convert a participant's accumulated benefit (or a portion thereof) to an annuity for the entire 5-year period ending on the plan termination date. As a result, the rules of paragraph (e)(2)(iii)(B) of this section apply to determine the annuity conversion factor used for purposes of converting a participant's accumulated benefit (or portion thereof) to an annuity for annuity starting dates after the plan termination date. For this purpose, if a separate mortality table and separate interest rate applied for a portion of the 5-year period, that mortality table and interest rate are used to calculate an annuity conversion factor and that factor is treated as having been the tabular annuity conversion factor that applied for that portion of the 5-year period for purposes of this paragraph (e)(2)(iii).

(D) Separate application with respect to optional forms. This paragraph (e)(2)(iii) applies separately with respect to each optional form of benefit on the date of plan termination. For this purpose, the term optional form of benefit has the meaning given that term in § 1.411(d)-3(g)(6)(ii), except that a change in the annuity conversion factor used to determine a particular benefit is disregarded in determining whether different optional forms exist. Thus, for example, if, for the entire 5-year period ending on the plan termination date, the plan provides for a mortality table in conjunction with an interest rate to be used to determine annuities other than qualified joint and survivor annuities, but for specified tabular factors to apply to determine annuities that are qualified joint and survivor annuities, then paragraph (e)(2)(iii)(A) of this section applies for purposes of annuities other than qualified joint and survivor annuities and paragraph (e)(2)(iii)(B) of this section applies for purposes of annuities that are qualified joint and survivor annuities. In addition, if the annuity conversion factor used to determine a particular qualified joint and survivor annuity has changed in the 5-year period ending on the plan termination date, the different factors are averaged for purposes of determining the annuity conversion factor that applies after plan termination for that particular qualified joint and survivor annuity.

(iv) Rules of application—(A) Average of interest rates for crediting interest—(1) In general. For purposes of determining the average of the interest rates under paragraph (e)(2)(ii) of this section, an interest crediting period is taken into account if the interest crediting date for the interest crediting period is within the 5-year period ending on the plan termination date. The average of the interest rates is determined as the arithmetic average of the annual interest rates used for those interest crediting periods. If the interest crediting periods taken into account are not all the same length, then each rate is weighted to reflect the length of the interest crediting period in which it applied. If the plan provides for the crediting of interest more frequently than annually, then interest credits after the plan termination date must be prorated in accordance with the rules of paragraph (d)(1)(iv)(C) of this section.

(2) Section 411(d)(6) protected accumulated benefit. In general, the interest rate that was used for each interest crediting period is the ongoing interest crediting rate that was specified under the plan for that period, without regard to any interest rate that was used prior to an amendment changing the interest crediting rate with respect to a section 411(d)(6) protected benefit. However, if, as of the end of the last interest crediting period that ends on or before the plan termination date, the participant's accumulated benefit is based on a section 411(d)(6) protected benefit that results from a prior amendment to change the rate of interest crediting applicable under the plan, then the pre-amendment interest rate is treated as having been used for each interest crediting period after the date of the interest crediting rate change (so that the amendment is disregarded).

(B) Average annuity conversion rates and factors—(1) In general. For purposes of determining average annuity conversion interest rates and average tabular annuity conversion factors under paragraph (e)(2)(iii) of this section, an interest rate or tabular annuity conversion factor is taken into account if the rate or conversion factor applied under the terms of the plan to convert a participant's accumulated benefit (or a portion thereof) to a benefit payable in the form of an annuity during the 5-year period ending on the plan termination date. The average is determined as the arithmetic average of the interest rates or tabular factors used during that period. If the periods in which the rates or factors that are averaged are not all the same length, then each rate or factor is weighted to reflect the length of the period in which it applied.

(2) Section 411(d)(6) protected annuity conversion factors. In general, the annuity conversion interest rate or tabular annuity conversion factor that was used for each period is the ongoing interest rate or tabular factor that was specified under the plan for that period, without regard to any rate or factor that was used under the plan prior to an amendment changing the rate or factor with respect to a section 411(d)(6) protected benefit. However, if, as of the plan termination date, the participant's annuity benefit for an annuity commencing at that date would be based on a section 411(d)(6) protected benefit that results from a prior amendment to change the rate or factor under the plan, then the pre-amendment rate or factor is treated as having been used after the date of the amendment (so that the amendment is disregarded).

(C) Blended rates. If, as of the plan termination date, the plan determines interest credits by applying different rates to two or more different predetermined portions of the accumulated benefit, then the interest crediting rate that applies after the plan termination date is determined separately with respect to each portion under the rules of paragraph (e)(2)(ii) of this section.

(D) Participants with less than 5 years of interest credits upon plan termination. If the plan provided for interest credits for any interest crediting period in which, pursuant to the terms of the plan, an individual was not eligible to receive interest credits (including because the individual was not a participant or beneficiary in the relevant interest crediting period), then, for purposes of determining the individual's average interest crediting rate under paragraph (e)(2)(ii) of this section, the individual is treated as though the individual received interest credits in that period using the interest crediting rate that applied in that period under the terms of the plan to a similarly situated participant or beneficiary who was eligible to receive interest credits.

(E) Plan termination date—(1) Plans subject to Title IV of ERISA. In the case of a plan that is subject to Title IV of ERISA, the plan termination date for purposes of this paragraph (e)(2) means the plan's termination date established under section 4048(a) of ERISA.

(2) Other plans. In the case of a plan that is not subject to Title IV of ERISA, the plan termination date for purposes of this paragraph (e)(2) means the plan's termination date established by the plan administrator, provided that the plan termination date may be no earlier than the date on which the actions necessary to effect the plan termination—other than the distribution of plan benefits—are taken. However, a plan is not treated as terminated on the plan's termination date if the assets are not distributed as soon as administratively feasible after that date. See Rev. Rul. 89-87 (1989-2 CB 2), (see § 601.601(d)(2)(ii)(b) of this chapter).

(v) Examples. The following examples illustrate the rules of this paragraph (e)(2). In each case, it is assumed that the plan is terminated in a standard termination.

(3) Rules relating to section 411(d)(6)—(i) General rule. The right to future interest credits determined in the manner specified under the plan and not conditioned on future service is a factor that is used to determine the participant's accrued benefit, for purposes of section 411(d)(6). Thus, to the extent that benefits have accrued under the terms of a statutory hybrid plan that entitle the participant to future interest credits, an amendment to the plan to change the interest crediting rate must satisfy section 411(d)(6) if the revised rate under any circumstances could result in interest credits that are smaller as of any date after the applicable amendment date (within the meaning of § 1.411(d)-3(g)(4)) than the interest credits that would be provided without regard to the amendment. For additional rules, see § 1.411(d)-3(b). Paragraphs (e)(3)(ii) through (e)(3)(vi) of this section set forth special rules that apply regarding the interaction of section 411(d)(6) and changes to a plan's interest crediting rate. The Commissioner may, in guidance of general applicability, prescribe additional rules regarding the interaction of section 411(d)(6) and section 411(b)(5), including changes to a plan's interest crediting rate. See § 601.601(d)(2)(ii)(b).

(ii) Adoption of long-term investment grade corporate bond rate. For purposes of applying section 411(d)(6) and this paragraph (e) to an amendment to change to the interest crediting rate described in paragraph (d)(3) of this section, a plan is not treated as providing interest credits that are smaller as of any date after the applicable amendment date than the interest credits that would be provided using an interest crediting rate described in paragraph (d)(4) of this section merely because the plan credits interest after the applicable amendment date using the interest crediting rate described in paragraph (d)(3) of this section, provided—

(A) The amendment only applies to interest credits to be credited after the effective date of the amendment;

(B) The effective date of the amendment is at least 30 days after adoption of the amendment;

(C) On the effective date of the amendment, the new interest crediting rate is not lower than the interest crediting rate that would have applied in the absence of the amendment; and

(D) For plan years described in paragraph (f)(2)(i)(B)(1) or (f)(2)(i)(B)(3) of this section (as applicable), if prior to the amendment the plan used a fixed annual floor in connection with a rate described in paragraph (d)(4)(ii), (iii) or (iv) of this section (as permitted under paragraph (d)(6)(ii) of this section), the floor is retained after the amendment to the maximum extent permissible under paragraph (d)(6)(ii)(A) of this section.

(iii) Coordination of section 411(d)(6) and market rate of return limitation—(A) In general. An amendment to a statutory hybrid plan that preserves a section 411(d)(6) protected benefit is subject to the rules under paragraph (d) of this section relating to market rate of return. However, in the case of an amendment to change a plan's interest crediting rate for periods after the applicable amendment date from one interest crediting rate (the old rate) that satisfies the requirements of paragraph (d) of this section to another interest crediting rate (the new rate) that satisfies the requirements of paragraph (d) of this section, the plan's effective interest crediting rate is not in excess of a market rate of return for purposes of paragraph (d) of this section merely because the plan provides for the benefit of any participant who is benefiting under the plan (within the meaning of § 1.410(b)-3(a)) on the applicable amendment date to never be less than what it would be if the old rate had continued but without taking into account any principal credits (as defined in paragraph (d)(1)(ii)(D) of this section) after the applicable amendment date.

(B) Multiple amendments. A pattern of repeated plan amendments each of which provides for a prospective change in the plan's interest crediting rate with respect to the benefit as of the applicable amendment date will be treated as resulting in the ongoing plan terms providing for an effective interest crediting rate that is in excess of a market rate of return. See § 1.411(d)-4, A-1(c)(1).

(iv) Change in lookback month or stability period used to determine interest credits—(A) Section 411(d)(6) anti-cutback relief. With respect to a plan using an interest crediting rate described in paragraph (d)(3) or (d)(4) of this section, notwithstanding the general rule of paragraph (e)(3)(i) of this section, if a plan amendment changes the lookback month or stability period used to determine interest credits, the amendment is not treated as reducing accrued benefits in violation of section 411(d)(6) merely on account of this change if the conditions of this paragraph (e)(3)(iv)(A) are satisfied. If the plan amendment is effective on or after the adoption date, any interest credits credited for the one-year period commencing on the date the amendment is effective must be determined using the lookback month and stability period provided under the plan before the amendment or the lookback month and stability period after the amendment, whichever results in the larger interest credits. If the plan amendment is adopted retroactively (that is, the amendment is effective prior to the adoption date), the plan must use the lookback month and stability period resulting in the larger interest credits for the period beginning with the effective date and ending one year after the adoption date.

(B) Section 411(b)(5)(B)(i)(I) market rate of return relief. The plan's effective interest crediting rate is not in excess of a market rate of return for purposes of paragraph (d) of this section merely because a plan amendment complies with the requirements of paragraph (e)(3)(iv)(A) of this section. However, a pattern of repeated plan amendments each of which provides for a change in the lookback month or stability period used to determine interest credits will be treated as resulting in the ongoing plan terms providing for an effective interest crediting rate that is in excess of a market rate of return. See § 1.411(d)-4, A-1(c)(1).

(v) RIC ceasing to exist. This paragraph (e)(3)(v) applies in the case of a statutory hybrid plan that credits interest using an interest crediting rate equal to the rate of return on a RIC (pursuant to paragraph (d)(5)(iv) of this section) that ceases to exist, whether as a result of a name change, liquidation, or otherwise. In such a case, the plan is not treated as violating section 411(d)(6) provided that the rate of return on the successor RIC is substituted for the rate of return on the RIC that no longer exists, for purposes of crediting interest for periods after the date the RIC ceased to exist. In the case of a name change or merger of RICs, the successor RIC means the RIC that results from the name change or merger involving the RIC that no longer exists. In all other cases, the successor RIC is a RIC selected by the plan sponsor that has reasonably similar characteristics, including characteristics related to risk and rate of return, as the RIC that no longer exists.

(vi) Transitional amendments needed to satisfy the market rate of return rules—(A) In general. Notwithstanding the requirements of section 411(d)(6), if the requirements set forth in this paragraph (e)(3)(vi) are satisfied, a plan may be amended to change its interest crediting rate with respect to benefits that have already accrued in order to comply with the requirements of section 411(b)(5)(B)(i) and paragraph (d) of this section. A plan amendment is eligible for the treatment provided under this paragraph (e)(3)(vi)(A) to the extent that the amendment modifies an interest crediting rate that does not satisfy the requirements of section 411(b)(5)(B)(i) and paragraph (d) of this section in the manner specified in paragraph (e)(3)(vi)(C) of this section.

(B) Rules of application—(1) Multiple noncompliant features. If a plan's interest crediting rate has more than one noncompliant feature as described in paragraph (e)(3)(vi)(C) of this section, then each noncompliant feature must be addressed separately in the manner specified in paragraph (e)(3)(vi)(C) of this section.

(2) Definition of investment-based rate. The application of the rules of paragraph (e)(3)(vi)(C) of this section to an interest crediting rate depends on whether the interest crediting rate is an investment-based rate. For purposes of this paragraph (e)(3)(vi), an investment-based rate is a rate based on either a rate of return provided by actual investments (taking into account the return attributable to any change in the value of the underlying investments) or a rate of return for an index that measures the change in the value of investments. A rate is an investment-based rate even if it is based only in part on a rate described in the preceding sentence.

(3) Timing rules for permitted amendments. The rules under this paragraph (e)(3)(vi) apply only to a plan amendment that is adopted prior to and effective no later than the first day of the first plan year described in paragraph (f)(2)(i)(B)(1) or (f)(2)(i)(B)(3) of this section, as applicable. In addition, the rules under this paragraph (e)(3)(vi) apply to a plan amendment only with respect to interest credits that are credited for interest crediting periods that begin on or after the applicable amendment date (within the meaning of § 1.411(d)-3(g)(4)).

(4) Amendments that provide for greater interest crediting rates. If a plan is amended in accordance with paragraphs (e)(3)(vi)(C)(1) through (10) of this section to switch from a noncompliant rate to a compliant rate and is subsequently amended to switch to a second compliant rate that can never be less than the first compliant rate, then the second amendment does not violate section 411(d)(6). If, instead, the plan is amended to switch from the noncompliant rate to the second compliant rate in a single amendment, that amendment also does not violate section 411(d)(6). For example, if it is permitted under paragraph (e)(3)(vi)(C) of this section to first amend the plan to credit interest using the lesser of the current rate and a rate described in paragraph (d)(3) of this section, it is then permissible to amend the plan to credit interest using that rate described in paragraph (d)(3) of this section. In such a case, it is also permissible to amend the plan to switch from the current rate to a rate described in paragraph (d)(3) of this section in a single amendment.

(5) Cumulative floors, including floors resulting from a prior change in rates with section 411(d)(6) protection. This paragraph (e)(3)(vi)(B)(5) applies to a plan that takes into account a minimum rate of return that applies less frequently than annually. This paragraph (e)(3)(vi)(B)(5) also applies to a plan that determines the participant's benefit as of the annuity starting date as the benefit provided by the greatest of two or more account balances (for example, in order to comply with section 411(d)(6) in connection with a prior amendment to change the plan's interest crediting rate). In either case, this paragraph (e)(3)(vi)(B)(5) applies with respect to a participant only if the requirements of paragraph (d)(6) of this section are not satisfied with respect to that participant. If this paragraph (e)(3)(vi)(B)(5) applies with respect to a participant, the plan must be amended to provide that the benefit for the participant is based solely on the benefit (and the associated interest crediting rate with respect to that benefit) that is greatest for that participant as of the applicable amendment date for the amendment made pursuant to this paragraph (e)(3)(vi). In addition, the plan must be further amended pursuant to the other rules in this paragraph (e)(3)(vi) if the remaining interest crediting rate does not satisfy the requirements of paragraph (d) of this section.

(6) Plans that permit participant direction of interest crediting rates. This paragraph (e)(3)(vi)(B)(6) applies in the case in which a plan permits a participant to choose an interest crediting rate from among a menu of hypothetical investment options and at least one of those hypothetical investment options provides for an interest crediting rate that is not permitted under paragraph (d) of this section (so that the plan fails to satisfy the requirements of paragraph (d) of this section). In such a case, the rules of this paragraph (e)(3)(vi) may be applied separately to correct each impermissible investment option. Alternatively, with respect to such a plan that permitted a participant to choose an interest crediting rate from among a menu of hypothetical investment options on September 18, 2014, pursuant to plan provisions that were adopted on or before September 18, 2014, the entire menu of investment options may be treated as an impermissible investment-based rate for which there is no permitted investment-based rate with similar risk and return characteristics (so that the rule of paragraph (e)(3)(vi)(C)(7) of this section does not apply). As a result, plans described in the preceding sentence may be amended to eliminate a participant's ability to choose an interest crediting rate from among a menu of hypothetical investment options in accordance with paragraph (e)(3)(vi)(C)(9) of this section.

(C) Noncompliant feature and amendment to bring plan into compliance—(1) Timing or other rules related to determining interest credits not satisfied. If a plan has an underlying interest rate that generally satisfies the rules of paragraph (d) of this section but that does not satisfy the rules relating to how interest credits are determined and credited as set forth in paragraph (d)(1)(iv) of this section, then the plan must be amended either—

(i) To correct the aspect of the plan's interest crediting rate that fails to comply with the rules of paragraph (d)(1)(iv) of this section with respect to its underlying interest crediting rate; or

(ii) If the plan's interest crediting rate is a variable rate that is not an investment-based rate of return, to provide that the plan's interest crediting rate is the lesser of that variable rate and a rate described in paragraph (d)(3) of this section that satisfies the rules of paragraph (d)(1)(iv) of this section.

(2) Fixed rate in excess of 6 percent. If a plan's interest crediting rate is a fixed rate in excess of the rate described in paragraph (d)(4)(v) of this section, then the plan must be amended to reduce the interest crediting rate to an annual interest crediting rate of 6 percent.

(3) Bond-based rate with margin exceeding maximum permitted margin. If a plan's interest crediting rate is a noncompliant rate that consists of an underlying rate described in paragraph (d)(3) or (d)(4) of this section except that the plan applies a margin that exceeds the maximum permitted margin under paragraph (d)(3) or (d)(4) of this section to the underlying rate, then the plan must be amended either—

(i) To reduce the margin to the maximum permitted margin for the underlying rate used by the plan; or

(ii) To provide that the plan's interest crediting rate is the lesser of the plan's noncompliant rate and a rate described in paragraph (d)(3) of this section (together with any fixed minimum rate that was part of the noncompliant rate, reduced to the extent necessary to comply with paragraph (d)(6)(ii) of this section).

(4) Bond-based rate with fixed minimum rate applied on an annual or more frequent basis in excess of the highest permitted fixed minimum rate. If a plan's interest crediting rate is a composite rate that consists of a variable rate described in paragraph (d)(3) or (d)(4) of this section in combination with a fixed minimum rate in excess of the highest permitted fixed minimum rate under paragraph (d)(6)(ii)(A)(2) or (B)(2) of this section (as applicable), then the plan must be amended in one of the following manners:

(i) To reduce the fixed minimum rate to the highest permitted fixed minimum rate that may be used in combination with the plan's variable rate;

(ii) To credit interest using an annual interest crediting rate of 6 percent; or

(iii) To provide that the plan's interest crediting rate is the lesser of the plan's noncompliant composite rate and a rate described in paragraph (d)(3) of this section (together with a fixed minimum rate of 4 percent).

(5) Greatest of two or more variable bond-based rates. If a plan's interest crediting rate is a composite rate that is the greatest of two or more variable rates described in paragraph (d)(3) or (d)(4) of this section, then the plan must be amended to provide for an interest crediting rate that is the lesser of the composite rate and a rate described in paragraph (d)(3) of this section.

(6) Other impermissible bond-based rates. If, after application of the rules of paragraphs (e)(3)(vi)(C)(1) through (5) of this section, a plan's interest crediting rate is a variable rate that is not an investment-based rate of return and is not described in paragraph (d)(3) or (d)(4) of this section, then the plan must be amended either—

(i) To provide for an interest crediting rate based on a variable rate described in paragraph (d)(3) or (d)(4) of this section that has similar duration and quality characteristics as the plan's variable rate, if such a rate can be selected; or

(ii) To provide for an interest crediting rate that is the lesser of the plan's variable rate and a rate described in paragraph (d)(3) of this section.

(7) Impermissible investment-based rate that can be replaced with a permissible rate that has similar risk and return characteristics. If a plan's interest crediting rate is an investment-based rate of return that is not described in paragraph (d)(5) of this section and a permitted investment-based rate described in paragraph (d)(5)(ii)(A), (d)(5)(ii)(B), or (d)(5)(iv) of this section that has similar risk and return characteristics as the plan's impermissible investment-based rate can be selected, then the plan must be amended to provide for an interest crediting rate based on such a permitted investment-based rate.

(8) Investment-based rate with an annual or more frequent minimum rate that is either a fixed rate or a non-investment based variable rate. If a plan's interest crediting rate is an investment-based rate of return that would be described in paragraph (d)(5) of this section except that the plan uses an annual or more frequent minimum rate that is either a fixed rate or a non-investment based variable rate in conjunction with the investment-based rate, then the plan must be amended either—

(i) To credit interest using that investment-based rate of return described in paragraph (d)(5) of this section without the minimum rate and eliminating any reduction (or other adjustment) to the investment-based rate; or

(ii) To provide that the plan's interest crediting rate is a rate described in paragraph (d)(3) of this section (together with any fixed minimum rate, reduced to the extent necessary to comply with paragraph (d)(6)(ii) of this section).

(9) Other impermissible investment-based rates. If, after application of the rules of paragraphs (e)(3)(vi)(C)(1), (7), and (8) of this section, a plan's interest crediting rate is an investment-based rate that is not described in paragraph (d)(5) of this section, then the plan must be amended either—

(i) To provide for an interest crediting rate that is an investment-based rate that is described in paragraph (d)(5) of this section and that is otherwise similar to the plan's impermissible investment-based rate but without the risk and return characteristics of the impermissible investment-based rate that caused it to be impermissible (generally requiring the use of a rate that is less volatile than the plan's impermissible investment-based rate but is otherwise similar to that rate); or

(ii) To provide that the plan's interest crediting rate is a rate described in paragraph (d)(3) of this section with a fixed minimum rate of 4 percent.

(D) Examples. The following examples illustrate the application of the rules of this paragraph (e)(3)(vi). Each plan has a plan year that is the calendar year, and all amendments are adopted on October 1, 2016, and become effective for interest crediting periods beginning on or after January 1, 2017. Except as otherwise provided, the interest crediting rate under the plan satisfies the timing and other rules related to crediting interest under paragraph (d)(1)(iv) of this section.

(vii) Plan termination amendments. A plan amendment with an applicable amendment date on or before the first day of the first plan year described in paragraph (f)(2)(i)(B)(1) or (3) of this section (as applicable) is not treated as reducing accrued benefits in violation of section 411(d)(6) merely because the amendment changes the rules that apply upon plan termination in order to satisfy the requirements of paragraph (e)(2) of this section.

(4) Actuarial increases after normal retirement age. A statutory hybrid plan is not treated as providing an effective interest crediting rate that is in excess of a market rate of return for purposes of paragraph (d) of this section merely because the plan provides that the participant's benefit, as of each annuity starting date after normal retirement age, is equal to the greater of—

(i) The benefit based on the accumulated benefit determined using an interest crediting rate that is not in excess of a market rate of return under paragraph (d) of this section; and

(ii) The benefit that satisfies the requirements of section 411(a)(2).

(5) Plans that permit participant direction of interest crediting rates. [Reserved]

(f) Effective/applicability date—(1) Statutory effective/applicability dates—(i) In general. Except as provided in paragraph (f)(1)(iii) of this section, section 411(b)(5) applies for periods beginning on or after June 29, 2005.

(ii) Conversion amendments. The requirements of section 411(b)(5)(B)(ii), 411(b)(5)(B)(iii), and 411(b)(5)(B)(iv) apply to a conversion amendment (as defined in paragraph (c)(4) of this section) that both is adopted on or after June 29, 2005, and takes effect on or after June 29, 2005.

(iii) Market rate of return—(A) Plans in existence on June 29, 2005—(1) In general. In the case of a plan that was in existence on June 29, 2005 (regardless of whether the plan was a statutory hybrid plan on that date), section 411(b)(5)(B)(i) applies to plan years that begin on or after January 1, 2008.

(2) Exception for plan sponsor election. Notwithstanding paragraph (f)(1)(iii)(A)(1) of this section, a plan sponsor of a plan that was in existence on June 29, 2005 (regardless of whether the plan was a statutory hybrid plan on that date) may elect to have the requirements of section 411(a)(13)(B) and section 411(b)(5)(B)(i) apply for any period on or after June 29, 2005, and before the first plan year beginning after December 31, 2007. In accordance with section 1107 of the PPA '06, an employer is permitted to adopt an amendment to make this election as late as the last day of the first plan year that begins on or after January 1, 2009 (January 1, 2011, in the case of a governmental plan as defined in section 414(d)) if the plan operates in accordance with the election.

(B) Plans not in existence on June 29, 2005. In the case of a plan not in existence on June 29, 2005, section 411(b)(5)(B)(i) applies to the plan on and after the later of June 29, 2005, and the date the plan becomes a statutory hybrid plan.

(iv) Collectively bargained plans—(A) In general. Notwithstanding paragraph (f)(1)(iii) of this section, in the case of a collectively bargained plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified on or before August 17, 2006, the requirements of section 411(b)(5)(B)(i) do not apply to plan years that begin before the earlier of—

(1) The later of—

(i) The date on which the last of those collective bargaining agreements terminates (determined without regard to any extension thereof on or after August 17, 2006); or

(ii) January 1, 2008; or

(2) January 1, 2010.

(B) Treatment of plans with both collectively bargained and non-collectively bargained employees. In the case of a plan with respect to which a collective bargaining agreement applies to some, but not all, of the plan participants, the plan is considered a collectively bargained plan for purposes of this paragraph (f)(1)(iv) if it is considered a collectively bargained plan under the rules of § 1.436-1(a)(5)(ii)(B).

(2) Effective/applicability date of regulations—(i) In general—(A) General effective date. Except as provided in paragraph (f)(2)(i)(B) of this section, this section applies to plan years that begin on or after January 1, 2011.

(B) Special effective date—(1) In general. Except as otherwise provided in this paragraph (f)(2)(i)(B), paragraphs (d)(1)(iii), (d)(1)(iv)(D) and (E), (d)(1)(vi), (d)(2)(ii) and (v), (d)(5)(ii)(B), (d)(5)(iv), (d)(6), (e)(2), (e)(3)(iii), (iv) and (v), and (e)(4) of this section apply to plan years that begin on or after January 1, 2017 (or an earlier date as elected by the taxpayer).

(2) Transitional amendments. Paragraphs (e)(3)(vi) and (vii) of this section apply to plan amendments made on or after September 18, 2014 (or an earlier date as elected by the taxpayer).

(3) Collectively bargained plans. In the case of a plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified on or before November 13, 2015, that constitutes a collectively bargained plan under the rules of § 1.436-1(a)(5)(ii)(B), the paragraphs referenced in paragraph (f)(2)(i)(B)(1) of this section apply to plan years that begin on or after the later of—

(i) January 1, 2017; and

(ii) The earlier of January 1, 2019; and the date on which the last of those collective bargaining agreements terminates (determined without regard to any extension thereof on or after November 13, 2015).

(ii) Conversion amendments. With respect to a conversion amendment (within the meaning of paragraph (c)(4) of this section), where the effective date of the conversion amendment (as defined in paragraph (c)(4)(vi) of this section) is on or after the statutory effective date set forth in paragraph (f)(1)(ii) of this section, the requirements of paragraph (c)(2) of this section apply only to a participant who has an hour of service on or after the regulatory effective date set forth in paragraph (f)(2)(i) of this section.

(iii) Reliance before regulatory effective date. For the periods after the statutory effective date set forth in paragraph (f)(1) of this section and before the regulatory effective date set forth in paragraph (f)(2)(i) of this section, the safe harbor and other relief of section 411(b)(5) apply and the market rate of return and other requirements of section 411(b)(5) must be satisfied. During these periods, a plan is permitted to rely on the provisions of this section for purposes of applying the relief and satisfying the requirements of section 411(b)(5).

(a) Accrued benefit derived from employer contributions. For purposes of section 411 and the regulations thereunder, under section 411(c)(1), an employee's accrued benefit derived from employer contributions under a plan as of any applicable date is the excess, if any, of—

(1) The total accrued benefit under the plan provided for the employee as of such date, over

(2) The accrued benefit provided for the employee, derived from contributions made by the employee under the plan as of such date.

For computation of accrued benefit derived from employee contributions to a defined contribution plan or from voluntary employee contributions to a defined benefit plan, see paragraph (b) of this section. For computation of accrued benefit derived from mandatory employee contributions to a defined benefit plan, see paragraph (c) of this section.

(b) Accrued benefit derived from employee contribution to defined contribution plan, etc. For purposes of section 411 and the regulations thereunder, under section 411(c)(2)(A) the accrued benefit derived from employee contributions to a defined contribution plan is determined under paragraph (b) (1) or (2) of this section, whichever applies. Under section 411(d)(5), the accrued benefit derived from voluntary employee contributions to a defined benefit plan is determined under paragraph (b)(1) of this section.

(1) Separate accounts maintained. If a separate account is maintained with respect to an employee's contributions and all income, expenses, gains, and losses attributable thereto, the accrued benefit determined under this subparagraph as of any applicable date is the balance of such account as of such date.

(2) Separate accounts not maintained. If a separate account is not maintained with respect to an employee's contributions and the income, expenses, gains, and losses attributable thereto, the accrued benefit determined under this subparagraph is the employee's total accrued benefit determined under the plan multiplied by a fraction—

(i) The numerator of which is the total amount of the employee's contributions under the plan less withdrawals, and

(ii) The denominator of which is the sum of (A) the amount described in paragraph (b)(2)(i) of this section, and (B) the total contributions made under the plan by the employer on behalf of the employee less withdrawals.

(c) Accrued benefit derived from mandatory employee contributions to a defined benefit plan—(1) General rule. In the case of a defined benefit plan (as defined in section 414(j)) the accrued benefit derived from contributions made by an employee under the plan as of any applicable date is an annual benefit, in the form of a single life annuity (without ancillary benefits) commencing at normal retirement age, equal to the amount of the employee's accumulated contributions (determined under paragraph (c)(3) of this section) multiplied by the appropriate conversion factor (determined under paragraph (c)(2) of this section). Paragraph (e) of this section provides rules for actuarial adjustments where the benefit is to be determined in a form other than the form described in this paragraph.

(2) Appropriate conversion factor. For purposes of this paragraph, the term “appropriate conversion factor” means the factor necessary to convert an amount equal to the accumulated contributions to a single life annuity (without ancillary benefits) commencing at normal retirement age and shall be 10 percent for a normal retirement age of 65 years. For other normal retirement ages the appropriate conversion factor shall be the factor as determined by the Commissioner.

(3) Accumulated contributions. For purposes of section 411(c) and this section, the term “accumulated contributions” means the total of—

(i) All mandatory contributions made by the employee (determined under paragraph (c)(4) of this section),

(ii) Interest (if any) on such contributions, computed at the rate provided by the plan to the end of the last plan year to which section 411(a)(2) does not apply (by reason of the applicable effective date), and

(iii) Interest on the sum of the amounts determined under paragraphs (c)(3)(i) and (ii) of this section compounded annually at the rate of 5 percent per annum from the beginning of the first plan year to which section 411(a)(2) applies (by reason of the applicable effective date) to the date on which the employee would attain normal retirement age.

(4) Mandatory contributions. For purposes of section 411(c) and this section the term “mandatory contributions” means amounts contributed to the plan by the employee which are required as a condition of his employment, as a condition of his participation in the plan, or as a condition of obtaining benefits (or additional benefits) under the plan attributable to employer contributions. For example, if the benefit derived from employer contributions depends upon a specified level of employee contributions, employee contributions up to that level would be treated as mandatory contributions. Mandatory contributions, otherwise satisfying the requirements of this subparagraph, include amounts contributed to the plan which are used to provide ancillary benefits such as incidental life insurance, health insurance, or death benefits.

(d) Limitation on accrued benefit. The accrued benefit derived from mandatory employee contributions under a defined benefit plan (determined under paragraph (c) of this section) shall not exceed the greater of—

(1) The accrued benefit of the employee under the plan, or

(2) The accrued benefit derived from employee contributions determined without regard to any interest under section 411(c)(2)(C) (ii) and (iii) and under paragraphs (c)(3) (ii) and (iii) of this section.

(e) Actuarial adjustments for defined benefit plans—(1) Accrued benefit. In the case of a defined benefit plan (as defined in section 414(j)) if an employee's accrued benefit is to be determined as an amount other than an annual benefit commencing at normal retirement age, such benefit (determined under section 411(c)(1) and paragraph (a) of this section) shall be the actuarial equivalent of such benefit, as determined by the Commissioner.

(2) Accrued benefit derived from employee contributions. In the case of a defined benefit plan (as defined in section 414(j) if the accrued benefit derived from mandatory contributions made by an employee is to be determined with respect to a benefit other than an annual benefit in the form of a single life annuity (without ancillary benefits) commencing at normal retirement age, such benefit shall be the actuarial equivalent of such benefit (determined under section 411(c)(2)(B) and paragraph (c) of this section) as determined by the Commissioner.

(f) Suspension of benefits, etc.—(1) Suspensions. No adjustment to an accrued benefit is required on account of any suspension of benefits if such suspension is permitted under section 203(a)(3)(B) of the Employee Retirement Income Security Act of 1974 (88 Stat. 855) (Code section 411(a)(3)(B)).

(2) Employment after retirement. No actuarial adjustment to an accrued benefit is required on account of employment after normal retirement age. For example, if a plan with a normal retirement age of 65 provides a benefit of $400 a month payable at age 65 the same $400 benefit (with no upward adjustment) could be paid to an employee who retires at age 68.

(a) General rule—(1) Required nonforfeitability. A plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) unless the plan provides that—

(i) Upon the termination or partial termination of the plan, or

(ii) In addition, in the case of a plan to which section 412 (relating to minimum funding standards) does not apply, upon the complete discontinuance of contributions under the plan,

(2) Required allocation. (i) A plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) unless the plan provides for the allocation of any previously unallocated funds to the employes covered by the plan upon the termination or partial termination of the plan (or, in the case of a plan to which section 412 does not apply, upon the complete discontinuance of contributions under the plan). Such provision may be incorporated in the plan at its inception or by an amendment made prior to the termination or partial termination of the plan for the discontinuance of contributions thereunder. In the case of a defined contribution plan under which unallocated forfeitures are held in a suspense account in order to satisfy the requirements of section 415, this subdivision shall not require such plan to provide for allocations from the suspense account to the extent that such allocations would result in annual additions to participants' accounts in excess of amounts permitted under section 415 for the year for which such allocations would be made.

(ii) Any provision for the allocation of unallocated funds which is found by the Secretary of Labor or the Pension Benefit Guaranty Corporation (whichever is appropriate) to satisfy the requirements of section 4044 or section 403(d)(1) of the Employee Retirement Income Security Act of 1974 is acceptable if it specifies the method to be used and does not conflict with the provisions of section 401(a)(4) of the Internal Revenue Code of 1954 and the regulations thereunder. Any allocation of funds required by paragraph (1), (2), (3), or (4)(A) of section 4044(a) of such Act shall be deemed not to result in discrimination prohibited by section 401(a)(4) of the Code (see, however, paragraph (e) of this section). Notwithstanding the preceding sentence, in the case of a plan which establishes subclasses or categories pursuant to section 4044(b)(6) of such Act, the allocation of funds by the use of such subclasses or categories shall not be deemed not to result in discrimination prohibited by the Code. The allocation of unallocated funds may be in cash or in the form of other benefits provided under the plan. However, the allocation of the funds contributed by the employer among the employees need not necessarily benefit all the employees covered by the plan.

(iii) Paragraphs (a)(2) (i) and (ii) of this section do not require the allocation of amounts to the account of any employee if such amounts are not required to be used to satisfy the liabilities with respect to employees and their beneficiaries under the plan (see section 401(a)(2)).

(b) Partial termination—(1) General rule. Whether or not a partial termination of a qualified plan occurs (and the time of such event) shall be determined by the Commissioner with regard to all the facts and circumstances in a particular case. Such facts and circumstances include: the exclusion, by reason of a plan amendment or severance by the employer, of a group of employees who have previously been covered by the plan; and plan amendments which adversely affect the rights of employees to vest in benefits under the plan.

(2) Special rule. If a defined benefit plan ceases or decreases future benefit accruals under the plan, a partial termination shall be deemed to occur if, as a result of such cessation or decrease, a potential reversion to the employer, or employers, maintaining the plan (determined as of the date such cessation or decrease is adopted) is created or increased. If no such reversion is created or increased, a partial termination shall be deemed not to occur by reason of such cessation or decrease. However, the Commissioner may determine that a partial termination of such a plan occurs pursuant to subparagraph (1) of this paragraph for reasons other than such cessation or decrease.

(3) Effect of partial termination. If a termination of a qualified plan occurs, the provisions of section 411(d)(3) apply only to the part of the plan that is terminated.

(c) Termination—(1) Application. This paragraph applies to a plan other than a plan described in section 411(e)(1) (relating to governmental, certain church plans, etc.).

(2) Plans subject to termination insurance. For purposes of this section, a plan to which title IV of the Employee Retirement Income Security Act of 1974 applies is considered terminated on a particular date if, as of that date—

(i) The plan is voluntarily terminated by the plan administrator under section 4041 of the Employee Retirement Income Security Act of 1974, or

(ii) The Pension Benefit Guaranty Corporation terminates the plan under section 4042 of the Employee Retirement Income Security Act of 1974.

(3) Other plans. In the case of a plan not described in paragraph (c)(2) of this section, a plan is considered terminated on a particular date if, as of that date, the plan is voluntarily terminated by the employer, or employers, maintaining the plan.

(d) Complete discontinuance—(1) General rule. For purposes of this section, a complete discontiuance of contributions under the plan is contrasted with a suspension of contributions under the plan which is merely a temporary cessation of contributions by the employer. A complete discontinuance of contributions may occur although some amounts are contributed by the employer under the plan if such amounts are not substantial enough to reflect the intent on the part of the employer to continue to maintain the plan. The determination of whether a complete discontinuance of contributions under the plan has occurred will be made with regard to all the facts and circumstances in the particular case, and without regard to the amount of any contributions made under the plan by employees. Among the factors to be considered in determining whether a suspension constitutes a discontinuance are:

(i) Whether the employer may merely be calling an actual discontinuance of contributions a suspension of such contributions in order to avoid the requirement of full vesting as in the case of a discontinuance, or for any other reason;

(ii) Whether contributions are recurring and substantial; and

(iii) Whether there is any reasonable probability that the lack of contributions will continue indefinitely.

(2) Time of discontinuance. In any case in which a suspension of a profit-sharing plan maintained by a single employer is considered a discontinuance, the discontinuance becomes effective not later than the last day of the taxable year of the employer following the last taxable year of such employer for which a substantial contribution was made under the profit-sharing plan. In the case of a profit-sharing plan maintained by more than one employer, the discontinuance becomes effective not later than the last day of the plan year following the plan year within which any employer made a substantial contribution under the plan.

(e) Contributions or benefits which remain forfeitable. Under section 411 (d) (2) and (3), section 411(a) and this section do not apply to plan benefits which may not be provided for designated employees in the event of early termination of the plan under provisions of the plan adopted pursuant to regulations prescribed by the Secretary or his delegate to preclude the discrimination prohibited by section 401(a)(4). Accordingly, in such a case, plan benefits may be required to be reallocated without regard to this section.

(a) Protection of accrued benefits—(1) General rule. Under section 411(d)(6)(A), a plan is not a qualified plan (and a trust forming a part of such plan is not a qualified trust) if a plan amendment decreases the accrued benefit of any plan participant, except as provided in section 412(d)(2) (section 412(c)(8) for plan years beginning before January 1, 2008), section 4281 of the Employee Retirement Income Security Act of 1974 as amended (ERISA), or other applicable law (see, for example, sections 418D and 418E of the Internal Revenue Code, and section 1107 of the Pension Protection Act of 2006, Public Law 109-280 (120 Stat. 780, 1063)). For purposes of this section, a plan amendment includes any changes to the terms of a plan, including changes resulting from a merger, consolidation, or transfer (as defined in section 414(l)) or a plan termination. The protection of section 411(d)(6) applies to a participant's entire accrued benefit under the plan as of the applicable amendment date, without regard to whether the entire accrued benefit was accrued before a participant's severance from employment or whether any portion was the result of an increase in the accrued benefit of the participant pursuant to a plan amendment adopted after the participant's severance from employment.

(2) Plan provisions taken into account—(i) Direct or indirect reduction in accrued benefit. For purposes of determining whether a participant's accrued benefit is decreased, all of the amendments to the provisions of a plan affecting, directly or indirectly, the computation of accrued benefits are taken into account. Plan provisions indirectly affecting the computation of accrued benefits include, for example, provisions relating to years of service and compensation.

(ii) Amendments effective with the same applicable amendment date. In determining whether a reduction in a participant's accrued benefit has occurred, all plan amendments with the same applicable amendment date are treated as one amendment. Thus, if two amendments have the same applicable amendment date and one amendment, standing alone, increases participants' accrued benefits and the other amendment, standing alone, decreases participants' accrued benefits, the amendments are treated as one amendment and will only violate section 411(d)(6) if, for any participant, the net effect is to decrease participants' accrued benefit as of that applicable amendment date.

(iii) Multiple amendments—(A) General rule. A plan amendment violates the requirements of section 411(d)(6) if it is one of a series of plan amendments that, when taken together, have the effect of reducing or eliminating a section 411(d)(6) protected benefit in a manner that would be prohibited by section 411(d)(6) if accomplished through a single amendment.

(B) Determination of the time period for combining plan amendments. For purposes of applying the rule in paragraph (a)(2)(iii)(A) of this section, generally only plan amendments adopted within a 3-year period are taken into account.

(3) Application of section 411(a) nonforfeitability provisions with respect to section 411(d)(6) protected benefits—(i) In general. The rules of this paragraph (a) apply to a plan amendment that decreases a participant's accrued benefits, or otherwise places greater restrictions or conditions on a participant's rights to section 411(d)(6) protected benefits, even if the amendment merely adds a restriction or condition that is permitted under the vesting rules in section 411(a)(3) through (11). However, such an amendment does not violate section 411(d)(6) to the extent it applies with respect to benefits that accrue after the applicable amendment date. See section 411(a)(10) and § 1.411(a)-8 for additional rules relating to changes in a plan's vesting schedule.

(ii) Exception for changes in a plan's vesting computation period. Notwithstanding paragraph (a)(3)(i) of this section, a plan amendment that satisfies the applicable requirements under 29 CFR 2530.203-2(c) (rules relating to vesting computation periods) does not fail to satisfy the requirements of section 411(d)(6) merely because the plan amendment changes the plan's vesting computation period.

(4) Changes in lookback months and stability periods for mortality table and interest rate. Subject to the rules of this paragraph (a)(4), a defined benefit plan may be amended by an amendment that is adopted on or after January 19, 2024 to change the stability period described in § 1.417(e)-1(d)(4)(ii) from one stability period to a different stability period or to change the lookback month described in § 1.417(e)-1(d)(4)(iii) from one lookback month to a different lookback month (including an indirect change to the stability period or lookback month as a result of a change in plan year). The amendments described in this paragraph (a)(4) may be made with respect to any plan provision under which an interest rate or mortality table is specified by reference to a stability period or a lookback month, provided that any distribution for which the annuity starting date occurs on or after the effective date of the amendment and before the end of the one-year period commencing on the applicable amendment date for the amendment is equal to the greater of—

(i) The amount determined using the pre-amendment stability period and lookback month; and

(ii) The amount determined using the post-amendment stability period and lookback month.

(5) Examples. The following examples illustrate the application of this paragraph (a):

(b) Protection of section 411(d)(6)(B) protected benefits—(1) General rule—(i) Prohibition against plan amendments eliminating or reducing section 411(d)(6)(B) protected benefits. Except as provided in this section, a plan is treated as decreasing an accrued benefit if it is amended to eliminate or reduce a section 411(d)(6)(B) protected benefit as defined in paragraph (g)(15) of this section. This paragraph (b)(1) applies to participants who satisfy (either before or after the plan amendment) the preamendment conditions for a section 411(d)(6)(B) protected benefit.

(ii) Contingent benefits. The rules of paragraph (b)(1)(i) of this section apply to participants who satisfy (either before or after the plan amendment) the preamendment conditions for the section 411(d)(6)(B) protected benefit even if the condition on which the eligibility for the section 411(d)(6)(B) protected benefit depends is an unpredictable contingent event (e.g., a plant shutdown).

(iii) Application of general rules in paragraph (a) of this section to section 411(d)(6)(B) protected benefits. For purposes of determining whether a participant's section 411(d)(6)(B) protected benefit is eliminated or reduced, the rules of paragraph (a) of this section apply to section 411(d)(6)(B) protected benefits in the same manner as they apply to accrued benefits described in section 411(d)(6)(A). As an example of the application of paragraph (a)(2)(ii) of this section to section 411(d)(6)(B) protected benefits, if there are two amendments with the same applicable amendment date and one amendment increases accrued benefits and the other amendment decreases the early retirement factors that are used to determine the early retirement annuity, the amendments are treated as one amendment and only violate section 411(d)(6) if, after the two amendments, the net dollar amount of any early retirement annuity with respect to the accrued benefit of any participant as of the applicable amendment date is lower than it would have been without the two amendments. As an example of the application of paragraph (a)(2)(iii) of this section to section 411(d)(6)(B) protected benefits, a series of amendments made within a 3-year period that, when taken together, have the effect of reducing or eliminating early retirement benefits or retirement-type subsidies in a manner that adversely affects the rights of any participant in a more than de minimis manner violates section 411(d)(6)(B) even if each amendment would be permissible pursuant to paragraphs (c), (d), or (f) of this section.

(2) Permissible elimination of section 411(d)(6)(B) protected benefits—(i) In general. A plan is permitted to be amended to eliminate a section 411(d)(6)(B) protected benefit if the elimination is in accordance with this section or § 1.411(d)-4.

(ii) Increases in payment amounts do not eliminate an optional form of benefit. An amendment is not treated as eliminating an optional form of benefit or eliminating or reducing an early retirement benefit or retirement-type subsidy under the plan, if, effective after the plan amendment, there is another optional form of benefit available to the participant under the plan that is of inherently equal or greater value (within the meaning of § 1.401(a)(4)-4(d)(4)(i)(A)). Thus, for example, a change in the method of calculating a joint and survivor annuity from using a 90% adjustment factor on account of the survivorship payment at particular ages for a participant and a spouse to using a 91% adjustment factor at the same ages is not treated as an elimination of an optional form of benefit. Similarly, a plan that offers a subsidized qualified joint and survivor annuity option for married participants under which the amount payable during the participant's lifetime is not less than the amount payable under the plan's straight life annuity is permitted to be amended to eliminate the straight life annuity option for married participants.

(3) Permissible elimination of benefits that are not section 411(d)(6) protected benefits—(i) In general. Section 411(d)(6) does not provide protection for benefits that are ancillary benefits, other rights and features, or any other benefits that are not described in section 411(d)(6). See § 1.411(d)-4, Q&A-1(d). However, a plan may not be amended to recharacterize a retirement-type benefit as an ancillary benefit. Thus, for example, a plan amendment to recharacterize any portion of an early retirement subsidy as a social security supplement that is an ancillary benefit violates section 411(d)(6).

(ii) No protection for future benefit accruals. Section 411(d)(6) only protects benefits that accrue before the applicable amendment date. Thus, a plan is permitted to be amended to eliminate or reduce an early retirement benefit, a retirement-type subsidy, or an optional form of benefit with respect to benefits that accrue after the applicable amendment date without violating section 411(d)(6). However, section 4980F(e) of the Internal Revenue Code and section 204(h) of ERISA require notice of an amendment to an applicable pension plan that either provides for a significant reduction in the rate of future benefit accrual or that eliminates or significantly reduces an early retirement benefit or a retirement-type subsidy. See § 54.4980F-1 of this chapter generally, and see § 54.4980F-1, Q&A-7(b) and Q&A-8(c) of this chapter, with respect to the circumstances under which such notice is required for a reduction in an early retirement benefit or retirement-type subsidy.

(4) Examples. The following examples illustrate the application of this paragraph (b):

(c) Permissible elimination of optional forms of benefit that are redundant—(1) General rule. Except as otherwise provided in paragraph (c)(5) of this section, a plan is permitted to be amended to eliminate an optional form of benefit for a participant with respect to benefits accrued before the applicable amendment date if—

(i) The optional form of benefit is redundant with respect to a retained optional form of benefit, within the meaning of paragraph (c)(2) of this section;

(ii) The plan amendment is not applicable with respect to an optional form of benefit with an annuity commencement date that is earlier than the number of days in the maximum QJSA explanation period (as defined in paragraph (g)(9) of this section) after the date the amendment is adopted; and

(iii) The requirements of paragraph (e) of this section are satisfied in any case in which either:

(A) The retained optional form of benefit for the participant does not commence on the same annuity commencement date as the optional form of benefit that is being eliminated; or

(B) As of the date the amendment is adopted, the actuarial present value of the retained optional form of benefit for the participant is less than the actuarial present value of the optional form of benefit that is being eliminated.

(2) Similar types of optional forms of benefit are redundant—(i) General rule. An optional form of benefit is redundant with respect to a retained optional form of benefit if, after the amendment becomes applicable—

(A) There is a retained optional form of benefit available to the participant that is in the same family of optional forms of benefit, within the meaning of paragraphs (c)(3) and (4) of this section, as the optional form of benefit being eliminated; and

(B) The participant's rights with respect to the retained optional form of benefit are not subject to materially greater restrictions (such as conditions relating to eligibility, restrictions on a participant's ability to designate the person who is entitled to benefits following the participant's death, or restrictions on a participant's right to receive an in-kind distribution) than applied to the optional form of benefit being eliminated.

(ii) Special rule for core options. An optional form of benefit that is a core option as defined in paragraph (g)(5) of this section may not be eliminated as a redundant benefit under the rules of this paragraph (c) unless the retained optional form of benefit and the eliminated core option are identical except for differences described in paragraph (c)(3)(ii) of this section. Thus, for example, a particular 10-year term certain and life annuity may not be eliminated by plan amendment unless the retained optional form of benefit is another 10-year term certain and life annuity.

(3) Family of optional forms of benefit—(i) In general. Paragraph (c)(4) of this section describes certain families of optional forms of benefits. Not every optional form of benefit that is offered under a plan necessarily fits within a family of optional forms of benefit as described in paragraph (c)(4) of this section. Each optional form of benefit that is not included in any particular family of optional forms of benefit listed in paragraph (c)(4) of this section is in a separate family of optional forms of benefit with other optional forms of benefit that would be identical to that optional form of benefit but for differences that are disregarded under paragraph (c)(3)(ii) of this section.

(ii) Certain differences among optional forms of benefit—(A) Differences in actuarial factors and annuity starting dates. The determination of whether two optional forms of benefit are within a family of optional forms of benefit is made without regard to actuarial factors or annuity starting dates. Thus, any optional forms of benefit that are part of the same generalized optional form (within the meaning of paragraph (g)(8) of this section) are in the same family of optional forms of benefit. For example, if a plan has a single-sum distribution option for some participants that is calculated using a 5% interest rate and a specific mortality table (but no less than the minimum present value as determined under section 417(e)) and another single-sum distribution option for other participants that is calculated using the applicable interest rate as defined in section 417(e)(3)(A)(ii)(II) and the applicable mortality table as defined in section 417(e)(3)(A)(ii)(I), both single-sum distribution options are part of the same generalized optional form and thus in the same family of optional forms of benefit under the rules of paragraph (c)(3)(i) of this section. However, differences in actuarial factors and annuity starting dates are taken into account for purposes of the requirements in paragraph (e)(3) of this section.

(B) Differences in pop-up provisions and cash refund features for joint and contingent options. The determination of whether two optional forms of benefit are within a family of optional forms of benefit relating to joint and contingent families (as described in paragraph (c)(4)(i) and (ii) of this section) is made without regard to the following features—

(1) Pop-up provisions (under which payments increase upon the death of the beneficiary or another event that causes the beneficiary not to be entitled to a survivor annuity);

(2) Cash refund features (under which payment is provided upon the death of the last annuitant in an amount that is not greater than the excess of the present value of the annuity at the annuity starting date over the total of payments before the death of the last annuitant); or

(3) Term-certain provisions for optional forms of benefit within a joint and contingent family.

(C) Differences in social security leveling features, refund of employee contributions features, and retroactive annuity starting date features. The determination of whether 2 optional forms of benefit are within a family of optional forms of benefit is made without regard to social security leveling features, refund of employee contributions features, or retroactive annuity starting date features. But see paragraph (c)(5) of this section for special rules relating to social security leveling, refund of employee contributions, and retroactive annuity starting date features in optional forms of benefit.

(4) List of families. The following are families of optional forms of benefit for purposes of this paragraph (c):

(i) Joint and contingent options with continuation percentages of 50% to 100%. An optional form of benefit is within the 50% or more joint and contingent family if it provides a life annuity to the participant and a survivor annuity to an individual that is at least 50% and no more than 100% of the annuity payable during the joint lives of the participant and the participant's survivor.

(ii) Joint and contingent options with continuation percentages less than 50%. An optional form of benefit is within the less than 50% joint and contingent family if it provides a life annuity to the participant and a survivor annuity to an individual that is less than 50% of the annuity payable during the joint lives of the participant and the participant's survivor.

(iii) Term certain and life annuity options with a term of 10 years or less. An optional form of benefit is within the 10 years or less term certain and life family if it is a life annuity with a guarantee that payments will continue to the participant's beneficiary for the remainder of a fixed period that is 10 years or less if the participant dies before the end of the fixed period.

(iv) Term certain and life annuity options with a term longer than 10 years. An optional form of benefit is within the longer than 10 years term certain and life family if it is a life annuity with a guarantee that payments will continue to the participant's beneficiary for the remainder of a fixed period that is in excess of 10 years if the participant dies before the end of the fixed period.

(v) Level installment payment options over a period of 10 years or less. An optional form of benefit is within the 10 years or less installment family if it provides for substantially level payments to the participant for a fixed period of at least 2 years and not in excess of 10 years with a guarantee that payments will continue to the participant's beneficiary for the remainder of the fixed period if the participant dies before the end of the fixed period.

(vi) Level installment payment options over a period of more than 10 years. An optional form of benefit is within the more than 10 years installment family if it provides for substantially level payments to the participant for a fixed period that is in excess of 10 years with a guarantee that payments will continue to the participant's beneficiary for the remainder of the fixed period if the participant dies before the end of the fixed period.

(5) Special rules for certain features included in optional forms of benefit. For purposes of applying this paragraph (c), to the extent an optional form of benefit that is being eliminated includes either a social security leveling feature or a refund of employee contributions feature, the retained optional form of benefit must also include that feature, and, to the extent that the optional form of benefit that is being eliminated does not include a social security leveling feature or a refund of employee contributions feature, the retained optional form of benefit must not include that feature. For purposes of applying this paragraph (c), to the extent an optional form of benefit that is being eliminated does not include a retroactive annuity starting date feature, the retained optional form of benefit must not include the feature.

(6) Separate application of redundancy rules for bifurcated benefits. If a plan permits the participant to make different distribution elections with respect to two or more separate portions of the participant's benefit, the rules of this paragraph (c) are permitted to be applied separately to each such portion of the participant's benefit as if that portion were the participant's entire benefit. Thus, for example, if one set of distribution elections applies to a portion of the participant's accrued benefit and another set of distribution elections applies to the other portion of the participant's accrued benefit, then with respect to one portion of the participant's benefit, the determination of whether any optional form of benefit is within a family of optional forms of benefit is permitted to be made disregarding elections that apply to the other portion of the participant's benefit. Similarly, if a participant can elect to receive any portion of the accrued benefit in a single sum and the remainder pursuant to a set of distribution elections, the rules of this paragraph (c) are permitted to be applied separately to the set of distribution elections that apply to the portion of the participant's accrued benefit that is not payable in a single sum (for example, for the portion of a participant's benefit that is not paid in a single sum, the determination of whether any optional form of benefit is within a family of optional forms of benefit is permitted to be made disregarding the fact that the other portion of the participant's benefit is paid in a single sum).

(d) Permissible elimination of noncore optional forms of benefit where core options are offered—(1) General rule. Except as otherwise provided in paragraph (d)(2) of this section, a plan is permitted to be amended to eliminate an optional form of benefit for a participant with respect to benefits accrued before the applicable amendment date if—

(i) After the amendment becomes applicable, each of the core options described in paragraph (g)(5) of this section is available to the participant with respect to benefits accrued before and after the amendment;

(ii) The plan amendment is not applicable with respect to an optional form of benefit with an annuity commencement date that is earlier than 4 years after the date the amendment is adopted; and

(iii) The requirements of paragraph (e) of this section are satisfied in any case in which either:

(A) One or more of the core options are not available commencing on the same annuity commencement date as the optional form of benefit that is being eliminated; or

(B) As of the date the amendment is adopted, the actuarial present value of the benefit payable under any core option with the same annuity commencement date is less than the actuarial present value of benefits payable under the optional form of benefit that is being eliminated.

(2) Special rules—(i) Treatment of certain features included in optional forms of benefit. For purposes of applying this paragraph (d), to the extent an optional form of benefit that is being eliminated includes either a social security leveling feature or a refund of employee contributions feature, at least one of the core options must also be available with that feature, and, to the extent that the optional form of benefit that is being eliminated does not include a social security leveling feature or a refund of employee contributions feature, each of the core options must be available without that feature. For purposes of applying this paragraph (d), to the extent an optional form of benefit that is being eliminated does not include a retroactive annuity starting date feature, each of the core options must be available without that feature.

(ii) Eliminating the most valuable option for a participant with a short life expectancy. For purposes of applying this paragraph (d), if the most valuable option for a participant with a short life expectancy (as defined in paragraph (g)(5)(iii) of this section) is eliminated, then, after the plan amendment, an optional form of benefit that is identical, except for differences described in paragraph (c)(3)(ii) of this section, must be available to the participant. However, such a plan amendment cannot eliminate a refund of employee contributions feature from the most valuable option for a participant with a short life expectancy.

(iii) Single-sum distributions. A plan amendment is not treated as satisfying this paragraph (d) if it eliminates an optional form of benefit that includes a single-sum distribution that applies with respect to at least 25% of the participant's accrued benefit as of the date the optional form of benefit is eliminated. But see § 1.411(d)-4, Q&A-2(b)(2)(v), relating to involuntary single-sum distributions for benefits with a present value not in excess of the maximum dollar amount in section 411(a)(11).

(iv) Application of multiple amendment rule to core option rule. Notwithstanding paragraph (a)(2)(iii)(B) of this section, if a plan is amended to eliminate an optional form of benefit using the core options rule in this paragraph (d), then the employer must wait 3 years after the first annuity commencement date for which the optional form of benefit is no longer available before making any changes to the core options offered under the plan (other than a change that is not treated as an elimination under paragraph (b)(2)(ii) of this section). Thus, for example, if a plan amendment eliminates an optional form of benefit for a participant using the core options rule under this paragraph (d), with an adoption date of January 1, 2006 and an effective date of January 1, 2010, the plan would not be permitted to be amended to make changes to the core options offered under the plan (and the core options would continue to apply with respect to the participant's accrued benefit) until January 1, 2013.

(v) Special rule for joint and contingent annuity core option. If a plan offers joint and contingent annuities under which a participant is entitled to a life annuity with a survivor annuity for the individual designated by the participant (including a non-spousal contingent annuitant) with continuation percentage options of both 50% and 100% (after adjustments permitted under paragraph (g)(5)(ii) of this section to comply with applicable law), the plan is permitted to treat both of these options as core options for purposes of this paragraph (d), in lieu of a 75% joint and contingent annuity. Thus, such a plan is permitted to use the rules of this paragraph (d) if the plan satisfies all of the requirements of this paragraph (d) (taking into account the modification rule in paragraph (g)(5)(ii) of this section) other than the requirement of offering a 75% joint and contingent annuity as described in paragraph (g)(5)(i)(B) of this section.

(e) Permissible plan amendments under paragraphs (c) and (d) eliminating or reducing section 411(d)(6)(B) protected benefits that are burdensome and of de minimis value—(1) In general. A plan amendment that, pursuant to paragraph (c)(1)(iii) or (d)(1)(iii) of this section, is required to satisfy this paragraph (e) satisfies this paragraph (e) if—

(i) The amendment eliminates section 411(d)(6)(B) protected benefits that create significant burdens or complexities for the plan and its participants as described in paragraph (e)(2) of this section; and

(ii) The amendment does not adversely affect the rights of any participant in a more than de minimis manner as described in paragraph (e)(3) of this section.

(2) Plan amendments eliminating section 411(d)(6)(B) protected benefits that create significant burdens and complexities—(i) Facts and circumstances analysis—(A) In general. The determination of whether a plan amendment eliminates section 411(d)(6)(B) protected benefits that create significant burdens or complexities for the plan and its participants is based on facts and circumstances.

(B) Early retirement benefits. In the case of an amendment that eliminates an early retirement benefit, relevant factors include whether the annuity starting dates under the plan considered in the aggregate are burdensome or complex (e.g., the number of categories of early retirement benefits, whether the terms and conditions applicable to the plan's early retirement benefits are difficult to summarize in a manner that is concise and readily understandable to the average plan participant, and whether those different early retirement benefits were added to the plan as a result of a plan merger, transfer, or consolidation), and whether the effect of the plan amendment is to reduce the number of categories of early retirement benefits.

(C) Retirement-type subsidies and actuarial factors. In the case of a plan amendment eliminating a retirement-type subsidy or changing the actuarial factors used to determine optional forms of benefit, relevant factors include whether the actuarial factors used for determining optional forms of benefit available under the plan considered in the aggregate are burdensome or complex (e.g., the number of different retirement-type subsidies and other actuarial factors available under the plan, whether the terms and conditions applicable to the plan's retirement-type subsidies are difficult to summarize in a manner that is concise and readily understandable to the average plan participant, whether the plan is eliminating one or more generalized optional forms, whether the plan is replacing a complex optional form of benefit that contains a retirement-type subsidy with a simpler form, and whether the different retirement-type subsidies and other actuarial factors were added to the plan as a result of a plan merger, transfer, or consolidation), and whether the effect of the plan amendment is to reduce the number of categories of retirement-type subsidies or other actuarial factors.

(D) Example. The following example illustrates the application of this paragraph (e)(2)(i):

(ii) Presumptions for certain amendments—(A) Presumption for amendments eliminating certain annuity starting dates. If the annuity starting dates under the plan considered in the aggregate are burdensome or complex, then elimination of any one of the annuity starting dates is presumed to eliminate section 411(d)(6)(B) protected benefits that create significant burdens or complexities for the plan and its participants. However, if the effect of a plan amendment with respect to a set of optional forms of benefit is merely to substitute one set of annuity starting dates for another set of annuity starting dates, without any reduction in the number of different annuity starting dates, then the plan amendment does not satisfy the requirements of this paragraph (e)(2).

(B) Presumption for amendments changing certain actuarial factors. If the actuarial factors used for determining benefit distributions available under a generalized optional form considered in the aggregate are burdensome or complex, then replacing some of the actuarial factors for the generalized optional form is presumed to eliminate section 411(d)(6)(B) protected benefits that create significant burdens or complexities for the plan and its participants. However, if the effect is merely to substitute one set of actuarial factors for another set of actuarial factors, without any reduction in the number of different actuarial factors or the complexity of those factors, then the plan amendment does not satisfy the requirements of this paragraph (e)(2) unless the change of actuarial factors is merely to replace one or more of the plan's actuarial factors for determining optional forms of benefit with new actuarial factors that are more accurate (e.g., reflecting more recent mortality experience or more recent market rates of interest).

(iii) Restrictions against creating burdens or complexities. See paragraphs (a)(2)(iii) and (b)(1)(iii) of this section for general rules applicable to multiple amendments. In accordance with these rules, a plan amendment does not eliminate a section 411(d)(6)(B) protected benefit that creates burdens and complexities for a plan and its participants if, less than 3 years earlier, a plan was previously amended to add another retirement-type subsidy in order to facilitate the elimination of the original retirement-type subsidy, even if the elimination of the other subsidy would not adversely affect the rights of any plan participant in a more than de minimis manner as provided in paragraph (e)(3) of this section.

(3) Elimination of early retirement benefits or retirement-type subsidies that are de minimis—(i) Rules for retained optional forms of benefit under paragraph (c) of this section. For purposes of paragraph (c) of this section, the elimination of an optional form of benefit does not adversely affect the rights of any participant in a more than de minimis manner if—

(A) The retained optional form of benefit described in paragraph (c) of this section has substantially the same annuity commencement date as the optional form of benefit that is being eliminated, as described in paragraph (e)(4) of this section; and

(B) Either the actuarial present value of the benefit payable in the optional form of benefit that is being eliminated does not exceed the actuarial present value of the benefit payable in the retained optional form of benefit by more than a de minimis amount, as described in paragraph (e)(5) of this section, or the amendment satisfies the requirements of paragraph (e)(6) of this section relating to a delayed effective date.

(ii) Rules for core options under paragraph (d) of this section. For purposes of paragraph (d) of this section, the elimination of an optional form of benefit does not adversely affect the rights of any participant in a more than de minimis manner if, with respect to each of the core options—

(A) The core option is available after the amendment with substantially the same annuity commencement date as the optional form of benefit that is being eliminated, as described in paragraph (e)(4) of this section; and

(B) Either the actuarial present value of the benefit payable in the optional form of benefit that is being eliminated does not exceed the actuarial present value of the benefit payable under the core option by more than a de minimis amount, as described in paragraph (e)(5) of this section, or the amendment satisfies the requirements of paragraph (e)(6) of this section.

(4) Definition of substantially the same annuity starting dates. For purposes of applying paragraphs (e)(3)(i)(A) and (ii)(A) of this section, annuity starting dates are considered substantially the same if they are within 6 months of each other.

(5) Definition of de minimis difference in actuarial present value. For purposes of applying paragraph (e)(3)(i)(B) and (ii)(B) of this section, a difference in actuarial present value between the optional form of benefit being eliminated and the retained optional form of benefit or core option is not more than a de minimis amount if, as of the date the amendment is adopted, the difference between the actuarial present value of the eliminated optional form of benefit and the actuarial present value of the retained optional form of benefit or core option is not more than the greater of—

(i) 2% of the present value of the retirement-type subsidy (if any) under the eliminated optional form of benefit prior to the amendment; or

(ii) 1% of the greater of the participant's compensation (as defined in section 415(c)(3)) for the prior plan year or the participant's average compensation for his or her high 3 years (within the meaning of section 415(b)(1)(B) and (b)(3)).

(6) Delayed effective date—(i) General rule. For purposes of applying paragraph (e)(3)(i)(B) and (ii)(B) of this section, an amendment that eliminates an optional form of benefit satisfies the requirements of this paragraph (e)(6) if the elimination of the optional form of benefit is not applicable to any annuity commencement date before the end of the expected transition period for that optional form of benefit.

(ii) Determination of expected transition period—(A) General rule. The expected transition period for a plan amendment eliminating an optional form of benefit is the period that begins when the amendment is adopted and ends when it is reasonable to expect, with respect to a section 411(d)(6)(B) protected benefit (i.e., not taking into account benefits that accrue in the future), that the form being eliminated would be subsumed by another optional form of benefit after taking into account expected future benefit accruals.

(B) Determination of expected transition period using conservative actuarial assumptions. The expected transition period for a plan amendment eliminating an optional form of benefit must be determined in accordance with actuarial assumptions that are reasonable at the time of the amendment and that are conservative (i.e., reasonable actuarial assumptions that are likely to result in the longest period of time until the eliminated optional form of benefit would be subsumed). For this purpose, actuarial assumptions are not treated as conservative unless they include assumptions that a participant's compensation will not increase and that future benefit accruals will not exceed accruals in recent periods.

(C) Effect of subsequent amendments reducing future benefit accruals on the expected transition period. If, during the expected transition period for a plan amendment eliminating an optional form of benefit, the plan is subsequently amended to reduce the rate of future benefit accrual (or otherwise to lengthen the expected transition period), thus that subsequent plan amendment must provide that the elimination of the optional form of benefit is void or must provide for the effective date for elimination of the optional form of benefit to be further extended to a new expected transition period that satisfies this paragraph (e)(6) taking into account the subsequent amendment.

(iii) Applicability of the delayed effective date rule limited to employees who continue to accrue benefits through the end of expected transition period. An amendment eliminating an optional form of benefit under this paragraph (e)(6) must be limited to participants who continue to accrue benefits under the plan through the end of the expected transition period. Thus, for example, the plan amendment may not apply to any participant who has a severance from employment during the expected transition period.

(iv) Special rule for section 204(h) notice. See § 54.4980F-1(b), Q&A-8(c) of this chapter for a special rule relating to this paragraph (e)(6).

(f) Utilization test—(1) General rule. A plan is permitted to be amended to eliminate all of the optional forms of benefit that comprise a generalized optional form (as defined in paragraph (g)(8) of this section) for a participant with respect to benefits accrued before the applicable amendment date if—

(i) None of the optional forms of benefit being eliminated is a core option, within the meaning of paragraph (g)(5) of this section;

(ii) The plan amendment is not applicable with respect to an optional form of benefit with an annuity commencement date that is earlier than the number of days in the maximum Qualified Joint and Survivor Annuity explanation period (as defined in paragraph (g)(9) of this section) after the date the amendment is adopted;

(iii) During the look-back period—

(A) The generalized optional form has been available to at least the applicable number of participants who are taken into account under paragraph (f)(3) and (4) of this section; and

(B) No participant has elected any optional form of benefit that is part of the generalized optional form with an annuity commencement date that is within the look-back period.

(2) Look-back period—(i) In general. For purposes of this paragraph (f), the look-back period is the period that includes—

(A) The portion of the plan year in which such plan amendment is adopted that precedes the date of adoption (the pre-adoption period); and

(B) The 2 plan years immediately preceding the pre-adoption period.

(ii) Special look-back period rules—(A) 12-month plan year. In the look-back period, at least 1 of the plan years must be a 12-month plan year.

(B) Permitted 3-month exclusion in the pre-adoption period. A plan is permitted to exclude from the look-back period the calendar month in which the amendment is adopted and the preceding 1 or 2 calendar months to the extent those preceding months are contained within the pre-adoption period.

(C) Permission to extend the look-back period. In order to have a look-back period that satisfies the minimum applicable number of participants requirement in paragraph (f)(1)(iii)(A) of this section, the look-back period described in paragraph (f)(2)(i)(B) of this section is permitted to be expanded, so as to include the 3, 4, or 5 plan years immediately preceding the plan year in which the amendment is adopted. Thus, in determining the look-back period, a plan is permitted to substitute the 3, 4, or 5 plan years immediately preceding the pre-adoption period for the 2 plan years described in paragraph (f)(2)(i)(B) of this section. However, if a plan does not satisfy the minimum applicable number of participants requirement of paragraph (f)(1)(iii)(A) of this section using the pre-adoption period and the immediately preceding 5 plan years, the plan is not permitted to be amended in accordance with the utilization test in this paragraph (f).

(3) Participants taken into account. A participant is taken into account for purposes of this paragraph (f) only if the participant was eligible to elect to commence payment of an optional form of benefit that is part of the generalized optional form being eliminated with an annuity commencement date that is within the look-back period. However, a participant is not taken into account if the participant—

(i) Did not elect any optional form of benefit with an annuity commencement date that was within the look-back period;

(ii) Elected an optional form of benefit that included a single-sum distribution that applied with respect to at least 25% of the participant's accrued benefit;

(iii) Elected an optional form of benefit that was only available during a limited period of time and that contained a retirement-type subsidy where the subsidy that is part of the generalized optional form being eliminated was not extended to any optional form of benefit with the same annuity commencement date; or

(iv) Elected an optional form of benefit with an annuity commencement date that was more than 10 years before normal retirement age.

(4) Determining the applicable number of participants. For purposes of applying the rules in this paragraph (f), the applicable number of participants is 50 participants. However, notwithstanding paragraph (f)(3)(ii) of this section, a plan is permitted to take into account any participant who elected an optional form of benefit that included a single-sum distribution that applied with respect to at least 25% of the participant's accrued benefit, but only if the applicable number of participants is increased to 1,000 participants.

(5) Default elections. For purposes of this paragraph (f), an election includes the payment of an optional form of benefit that applies in the absence of an affirmative election.

(g) Definitions and use of terms. The definitions in this paragraph (g) apply for purposes of this section.

(1) Actuarial present value. The term actuarial present value means actuarial present value (within the meaning of § 1.401(a)(4)-12) determined using reasonable actuarial assumptions.

(2) Ancillary benefit. The term ancillary benefit means—

(i) A social security supplement under a defined benefit plan (other than a QSUPP as defined in § 1.401(a)(4)-12);

(ii) A benefit payable under a defined benefit plan in the event of disability (to the extent that the benefit exceeds the benefit otherwise payable), but only if the total benefit payable in the event of disability does not exceed the maximum qualified disability benefit, as defined in section 411(a)(9);

(iii) A life insurance benefit;

(iv) A medical benefit described in section 401(h);

(v) A death benefit under a defined benefit plan other than a death benefit which is a part of an optional form of benefit; or

(vi) A plant shutdown benefit or other similar benefit in a defined benefit plan that does not continue past retirement age and does not affect the payment of the accrued benefit, but only to the extent that such plant shutdown benefit, or other similar benefit (if any), is permitted in a qualified pension plan (see § 1.401-1(b)(1)(i)).

(3) Annuity commencement date. The term annuity commencement date generally means the annuity starting date, except that, in the case of a retroactive annuity starting date under section 417(a)(7), annuity commencement date means the date of the first payment of benefits pursuant to a participant election of a retroactive annuity starting date, as defined in § 1.417(e)-1(b)(3)(iv).

(4) Applicable amendment date. The term applicable amendment date, with respect to a plan amendment, means the later of the effective date of the amendment or the date the amendment is adopted.

(5) Core options—(i) General rule. With respect to a plan, the term core options means—

(A) A straight life annuity generalized optional form under which the participant is entitled to a level life annuity with no benefit payable after the participant's death;

(B) A 75% joint and contingent annuity generalized optional form under which the participant is entitled to a life annuity with a survivor annuity for any individual designated by the participant (including a non-spousal contingent annuitant) that is 75% of the amount payable during the participant's life (but see paragraph (d)(2)(v) of this section for a special rule relating to the joint and contingent annuity core option);

(C) A 10-year term certain and life annuity generalized optional form under which the participant is entitled to a life annuity with a guarantee that payments will continue to any person designated by the participant for the remainder of a fixed period of 10 years if the participant dies before the end of the 10-year period; and

(D) The most valuable option for a participant with a short life expectancy (as defined in paragraph (g)(5)(iii) of this section).

(ii) Modification of core options to satisfy other requirements. An annuity does not fail to be a core option (e.g., a joint and contingent annuity described in paragraph (g)(5)(i)(B) of this section or a 10-year term certain and life annuity described in paragraph (g)(5)(i)(C) of this section) as a result of differences to comply with applicable law, such as limitations on death benefits to comply with the incidental benefit requirement of § 1.401-1(b)(1)(i) or on account of the spousal consent rules of section 417.

(iii) Most valuable option for a participant with a short life expectancy—(A) General definition. Except as provided in paragraph (g)(5)(iii)(B) of this section, most valuable option for a participant with a short life expectancy means, for an annuity starting date, the optional form of benefit that is reasonably expected to result in payments that have the largest actuarial present value in the case of a participant who dies shortly after the annuity starting date, taking into account both payments due to the participant prior to the participant's death and any payments due after the participant's death. For this purpose, a plan is permitted to assume that the spouse of the participant is the same age as the participant. In addition, a plan is permitted to assume that the optional form of benefit that is the most valuable option for a participant with a short life expectancy when the participant is age 70 1/2 also is the most valuable option for a participant with a short life expectancy at all older ages, and that the most valuable option for a participant with a short life expectancy at age 55 is the most valuable option for a participant with a short life expectancy at all younger ages.

(B) Safe harbor hierarchy—(1) A plan is permitted to treat a single-sum distribution option with an actuarial present value that is not less than the actuarial present value of any optional form of benefit eliminated by the plan amendment as the most valuable option for a participant with a short life expectancy for all of a participant's annuity starting dates if such single-sum distribution option is available at all such dates, without regard to whether the option was available before the plan amendment.

(2) If the plan before the amendment does not offer a single-sum distribution option as described in paragraph (g)(5)(iii)(B)(1) of this section, a plan is permitted to treat a joint and contingent annuity with a continuation percentage that is at least 75% and that is at least as great as the highest continuation percentage available before the amendment as the most valuable option for a participant with a short life expectancy for all of a participant's annuity starting dates if such joint and contingent annuity is available at all such dates, without regard to whether the option was available before the plan amendment.

(3) If the plan before the amendment offers neither a single-sum distribution option as described in paragraph (g)(5)(iii)(B)(1) of this section nor a joint and contingent annuity with a continuation percentage as described in paragraph (g)(5)(iii)(B)(2) of this section, a plan is permitted to treat a term certain and life annuity with a term certain period no less than 15 years as the most valuable option for a participant with a short life expectancy for each annuity starting date if such 15-year term certain and life annuity is available at all annuity starting dates, without regard to whether the option was available before the plan amendment.

(6) Definitions of types of section 411(d)(6)(B) protected benefits—(i) Early retirement benefit. The term early retirement benefit means the right, under the terms of a plan, to commence distribution of a retirement-type benefit at a particular date after severance from employment with the employer and before normal retirement age. Different early retirement benefits result from differences in terms relating to timing.

(ii) Optional form of benefit—(A) In general. The term optional form of benefit means a distribution alternative (including the normal form of benefit) that is available under the plan with respect to an accrued benefit or a distribution alternative with respect to a retirement-type benefit. Different optional forms of benefit exist if a distribution alternative is not payable on substantially the same terms as another distribution alternative. The relevant terms include all terms affecting the value of the optional form, such as the method of benefit calculation and the actuarial factors or assumptions used to determine the amount distributed. Thus, for example, different optional forms of benefit may result from differences in terms relating to the payment schedule, timing, commencement, medium of distribution (e.g., in cash or in kind), election rights, differences in eligibility requirements, or the portion of the benefit to which the distribution alternative applies. Likewise, differences in the normal retirement ages of employees or in the form in which the accrued benefit of employees is payable at normal retirement age under a plan are taken into account in determining whether a distribution alternative constitutes one or more optional forms of benefit.

(B) Death benefits. If a death benefit is payable after the annuity starting date for a specific optional form of benefit and the same death benefit would not be provided if another optional form of benefit were elected by a participant, then that death benefit is part of the specific optional form of benefit and is thus protected under section 411(d)(6). A death benefit is not treated as part of a specific optional form of benefit merely because the same benefit is not provided to a participant who has received his or her entire accrued benefit prior to death. For example, a $5,000 death benefit that is payable to all participants except any participant who has received his or her accrued benefit in a single-sum distribution is not part of a specific optional form of benefit.

(iii) Retirement-type benefit. The term retirement-type benefit means—

(A) The payment of a distribution alternative with respect to an accrued benefit; or

(B) The payment of any other benefit under a defined benefit plan (including a QSUPP as defined in § 1.401(a)(4)-12) that is permitted to be in a qualified pension plan, continues after retirement, and is not an ancillary benefit.

(iv) Retirement-type subsidy. The term retirement-type subsidy means the excess, if any, of the actuarial present value of a retirement-type benefit over the actuarial present value of the accrued benefit commencing at normal retirement age or at actual commencement date, if later, with both such actuarial present values determined as of the date the retirement-type benefit commences. Examples of retirement-type subsidies include a subsidized early retirement benefit and a subsidized qualified joint and survivor annuity.

(v) Subsidized early retirement benefit or early retirement subsidy. The terms subsidized early retirement benefit or early retirement subsidy mean the right, under the terms of a plan, to commence distribution of a retirement-type benefit at a particular date after severance from employment with the employer and before normal retirement age where the actuarial present value of the optional forms of benefit available to the participant under the plan at that annuity starting date exceeds the actuarial present value of the accrued benefit commencing at normal retirement age (with such actuarial present values determined as of the annuity starting date). Thus, an early retirement subsidy is an early retirement benefit that provides a retirement-type subsidy.

(7) Eliminate; elimination; reduce; reduction. The terms eliminate or elimination when used in connection with a section 411(d)(6)(B) protected benefit mean to eliminate or the elimination of an optional form of benefit or an early retirement benefit and to reduce or a reduction in a retirement-type subsidy. The terms reduce or reduction when used in connection with a retirement-type subsidy mean to reduce or a reduction in the amount of the subsidy. For purposes of this section, an elimination includes a reduction and a reduction includes an elimination.

(8) Generalized optional form. The term generalized optional form means a group of optional forms of benefit that are identical except for differences due to the actuarial factors that are used to determine the amount of the distributions under those optional forms of benefit and the annuity starting dates.

(9) Maximum QJSA explanation period. The term maximum QJSA explanation period means the maximum number of days before an annuity starting date for a qualified joint and survivor annuity for which a written explanation relating to the qualified joint and survivor annuity would satisfy the timing requirements of section 417(a)(3) and § 1.417(e)-1(b)(3)(ii).

(10) Other right and feature. The term other right or feature has the meaning set forth at § 1.401(a)(4)-4(e)(3)(ii).

(11) Refund of employee contributions feature. The term refund of employee contributions features means a feature with respect to an optional form of benefit that provides for employee contributions and interest thereon to be paid in a single sum at the annuity starting date with the remainder to be paid in another form beginning on that date.

(12) Retirement; retirement age. For purposes of this section, the date of retirement means the annuity starting date. Thus, retirement age means a participant's age at the annuity starting date.

(13) Retroactive annuity starting date feature. The term retroactive annuity starting date feature means a feature with respect to an optional form of benefit under which the annuity starting date for the distribution occurs on or before the date the written explanation required by section 417(a)(3) is provided to the participant.

(14) Section 411(d)(6) protected benefit. The term section 411(d)(6) protected benefit means the accrued benefit of a participant as of the applicable amendment date described in section 411(d)(6)(A) and any section 411(d)(6)(B) protected benefit.

(15) Section 411(d)(6)(B) protected benefit. The term section 411(d)(6)(B) protected benefit means the portion of an early retirement benefit, a retirement-type subsidy, or an optional form of benefit attributable to benefits accrued before the applicable amendment date.

(16) Social security leveling feature. The term social security leveling feature means a feature with respect to an optional form of benefit commencing prior to a participant's expected commencement of social security benefits that provides for a temporary period of higher payments which is designed to result in an approximately level amount of income when the participant's estimated old age benefits from Social Security are taken into account.

(h) Examples. The following examples illustrate the application of paragraphs (c) through (g) of this section:

(i) [Reserved]

(j) Effective dates—(1) General effective date. Except as otherwise provided in this paragraph (j), the rules of this section apply to amendments adopted on or after August 12, 2005.

(2) Effective date for rules relating to contingent event benefits. Paragraph (b)(1)(ii) of this section applies to amendments adopted after December 31, 2005.

(3) Effective dates for rules relating to section 411(a) nonforfeitability provisions—(i) Application of suspension of benefit rules to section 411(d)(6) protected benefits. With respect to a plan amendment that places greater restrictions or conditions on a participant's rights to section 411(d)(6) protected benefits by adding or modifying a plan provision relating to suspension of benefit payments during a period of employment or reemployment, the rules provided in paragraph (a)(3) of this section apply to periods beginning on or after June 7, 2004.

(ii) Application of section 411(a) nonforfeitability provisions to section 411(d)(6) protected benefits. With respect to a plan amendment that places greater restrictions or conditions on a participant's rights to section 411(d)(6) protected benefits other than a plan amendment described in paragraph (j)(3)(i) of this section, the rules provided in paragraph (a)(3) of this section apply to plan amendments adopted after August 9, 2006.

(4) Effective date for change to redundancy rule regarding bifurcation of benefits. The rules provided in paragraph (c)(6) of this section are applicable for amendments adopted after August 9, 2006.

Q-1: What are “section 411(d)(6) protected benefits”?

A-1: (a) In general. The term “section 411(d)(6) protected benefit” includes any benefit that is described in one or more of the following categories—

(1) Benefits described in section 411(d)(6)(A),

(2) Early retirement benefits (as defined in § 1.411(d)-3(g)(6)(i)) and retirement-type subsidies (as defined in § 1.411(d)-3(g)(6)(iv)), and

(3) Optional forms of benefit described in section 411(d)(6)(B)(ii).

(b) Optional forms of benefit—(1) In general. The term optional form of benefit has the same meaning as in § 1.411(d)-3(g)(6)(ii). Under this definition, different optional forms of benefit exist if a distribution alternative is not payable on substantially the same terms as another distribution alternative. Thus, for example, different optional forms of benefit may result from differences in terms relating to the payment schedule, timing, commencement, medium of distribution (e.g., in cash or in kind), election rights, differences in eligibility requirements, or the portion of the benefit to which the distribution alternative applies.

(2) Examples. The following examples illustrate the meaning of the term “optional form of benefit.” Other issues, such as the requirement that the optional forms satisfy section 401(a)(4), are not addressed in these examples and no inferences are intended with respect to such requirements. Assume that the distribution forms, including those not described in these examples, provided under the plan in each of the following examples are identical in all respects not described.

(c) Plan terms—(1) General rule. Generally, benefits described in section 411(d)(6)(A), early retirement benefits, retirement-type subsidies, and optional forms of benefit are section 411(d)(6) protected benefits only if they are provided under the terms of a plan. However, if an employer establishes a pattern of repeated plan amendments providing for similar benefits in similar situations for substantially consecutive, limited periods of time, such benefits will be treated as provided under the terms of the plan, without regard to the limited periods of time, to the extent necessary to carry out the purposes of section 411(d)(6) and, where applicable, the definitely determinable requirement of section 401(a), including section 401(a)(25). A pattern of repeated plan amendments providing that a particular optional form of benefit is available to certain named employees for a limited period of time is within the scope of this rule and may result in such optional form of benefit being treated as provided under the terms of the plan to all employees covered under the plan without regard to the limited period of time and the limited group of named employees.

(2) Effective date. The provisions of paragraph (c)(1)of this Q&A-1 are effective as of July 11, 1988. Thus, patterns or repeated plan amendments adopted and effective before July 11, 1988 will be disregarded in determining whether such amendments have created an ongoing optional form of benefit under the plan.

(d) Benefits that are not section 411(d)(6) protected benefits. The following benefits are examples of items that are not section 411(d)(6) protected benefits:

(1) Ancillary life insurance protection;

(2) Accident or health insurance benefits;

(3) Social security supplements described in section 411(a)(9), except qualified social security supplements as defined in § 1.401(a)(4)-12;

(4) The availability of loans (other than the distribution of an employee's accrued benefit upon default under a loan);

(5) The right to make after-tax employee contributions or elective deferrals described in section 402(g)(3);

(6) The right to direct investments;

(7) The right to a particular form of investment (e.g., investment in employer stock or securities or investment in certain types of securities, commercial paper, or other investment media);

(8) The allocation dates for contributions, forfeitures, and earnings, the time for making contributions (but not the conditions for receiving an allocation of contributions or forfeitures for a plan year after such conditions have been satisfied), and the valuation dates for account balances;

(9) Administrative procedures for distributing benefits, such as provisions relating to the particular dates on which notices are given and by which elections must be made; and

(10) Rights that derive from administrative and operational provisions, such as mechanical procedures for allocating investment experience among accounts in defined contribution plans.

Q-2: To what extent may section 411(d)(6) protected benefits under a plan be reduced or eliminated?

A-2:

(a) Reduction or elimination of section 411(d)(6) protected benefits—(1) In general. A plan is not permitted to be amended to eliminate or reduce a section 411(d)(6) protected benefit that has already accrued, except as provided in § 1.411(d)-3 or this section. This is generally the case even if such elimination or reduction is contingent upon the employee's consent. However, a plan may be amended to eliminate or reduce section 411(d)(6) protected benefits with respect to benefits not yet accrued as of the later of the amendment's adoption date or effective date without violating section 411(d)(6).

(2) Selection of optional forms of benefit—(i) General rule. A plan may treat a participant as receiving his entire nonforfeitable accrued benefit under the plan if the participant receives his benefit in an optional form of benefit in an amount determined under the plan that is at least the actuarial equivalent of the employee's nonforfeitable accrued benefit payable at normal retirement age under the plan. This is true even though the participant could have elected to receive an optional form of benefit with a greater actuarial value than the value of the optional form received, such as an optional form including retirement-type subsidies, and without regard to whether such other, more valuable optional form could have commenced immediately or could have become available only upon the employee's future satisfaction of specified eligibility conditions.

(ii) Election of an optional form. Except as provided in paragraph (a)(2)(iii) of this Q&A-2, a plan does not violate section 411(d)(6) merely because an employee's election to receive a portion of his nonforfeitable accrued benefit in one optional form of benefit precludes the employee from receiving that portion of his benefit in another optional form of benefit. Such employee retains all 411(d)(6) protected rights with respect to the entire portion of such employee's nonforfeitable accrued benefit for which no distribution election was made. For purposes of this rule, an elective transfer of an otherwise distributable benefit is treated as the selection of an optional form of benefit. See Q&A-3 of this section.

(iii) Buy-back rule. Notwithstanding paragraph (a)(2)(ii) of this Q&A-2, an employee who received a distribution of his nonforfeitable benefit from a plan that is required to provide a repayment opportunity to such employee if he returns to service within the applicable period pursuant to the requirements of section 411(a)(7) and who, upon subsequent reemployment, repays the full amount of such distribution in accordance with section 411(a)(7)(C) must be reinstated in the full array of section 411(d)(6) protected benefits that existed with respect to such benefit prior to distribution.

(iv) Examples. The rules in this paragraph (a)(2) can be illustrated by the following examples:

(3) Certain transactions—(i) Plan mergers and benefit transfers. The prohibition against the reduction or elimination of section 411(d)(6) protected benefits already accrued applies to plan mergers, spinoffs, transfers, and transactions amending or having the effect of amending a plan or plans to transfer plan benefits. Thus, for example, if plan A, a profit-sharing plan that provides for distribution of plan benefits in annual installments over ten or twenty years, is merged with plan B, a profit-sharing plan that provides for distribution of plan benefits in annual installments over life expectancy at time of retirement, the merged plan must retain the ten or twenty year installment option for participants with respect to benefits already accrued under plan A as of the merger and the installments over life expectancy for participants with benefits already accrued under plan B. Similarly, for example, if an employee's benefit under a defined contribution plan is transferred to another defined contribution plan (whether or not of the same employer), the optional forms of benefit available with respect to the employee's benefit accrued under the transferor plan may not be eliminated or reduced except as otherwise permitted under this regulation. See Q&A-3 of this section with respect to the transfer of benefits between and among defined benefit and defined contribution plans.

(ii) Annuity contracts—(A) General rule. The right of a participant to receive a benefit in the form of cash payments from the plan and the right of a participant to receive that benefit in the form of the distribution of an annuity contract that provides for cash payments that are identical in all respects to the cash payments from the plan except with respect to the source of the payments are not separate optional forms of benefit. Therefore, for example, if a plan includes an optional form of benefit under which benefits are distributed in the medium of an annuity contract that provides for cash payments, that optional form of benefit may be modified by a plan amendment that substitutes cash payments from the plan for the annuity contract, where those cash payments from the plan are identical to the cash payments payable from the annuity contract in all respects except with respect to the source of the payments. The protection provided by section 411(d)(6) may not be avoided by the use of annuity contracts. Thus, section 411(d)(6) protected benefits already accrued may not be eliminated or reduced merely because a plan uses annuity contracts to provide such benefits, without regard to whether the plan, a participant, or a beneficiary of a participant holds the contract or whether such annuity contracts are purchased as a result of the termination of the plan. However, to the extent that an annuity contract constitutes payment of benefits in a particular optional form elected by the participant, the plan does not violate section 411(d)(6) merely because it provides that other optional forms are no longer available with respect to such participant. See paragraph (a)(2) of this Q&A-2.

(B) Examples. The provisions of this paragraph (a)(3)(ii) can be illustrated by the following examples:

(4) Benefits payable to a spouse or beneficiary. Section 411(d)(6) protected benefits may not be eliminated merely because they are payable with respect to a spouse or other beneficiary.

(b) Section 411(d)(6) protected benefits that may be eliminated or reduced only as permitted by the Commissioner—(1) In general. The Commissioner may, consistent with the provisions of this section, provide for the elimination or reduction of section 411(d)(6) protected benefits that have already accrued only to the extent that such elimination or reduction does not result in the loss to plan participants of either a valuable right or an employer-subsidized optional form of benefit where a similar optional form of benefit with a comparable subsidy is not provided or to the extent such elimination or reduction is necessary to permit compliance with other requirements of section 401(a) (e.g., sections 401(a)(4), 401(a)(9) and 415). The Commissioner may exercise this authority only through the publication of revenue rulings, notices, and other documents of general applicability.

(2) Section 411(d)(6) protected benefits that may be eliminated or reduced. The elimination or reduction of certain section 411(d)(6) protected benefits that have already accrued in the following situations does not violate section 411(d)(6). The rules with respect to permissible eliminations and reductions provided in this paragraph (b)(2) generally are effective January 30, 1986; however, the rules of paragraphs (b)(2)(iii) (A) and (B) and (b)(2)(viii) of this Q&A-2 are effective for plan amendments that are adopted and effective on or after September 6, 2000. These exceptions create no inference with respect to whether any other applicable requirements are satisfied (for example, requirements imposed by section 401(a)(9) and section 401(a)(14)).

(i) Change in statutory requirement. A plan may be amended to eliminate or reduce a section 411(d)(6) protected benefit if the following three requirements are met: the amendment constitutes timely compliance with a change in law affecting plan qualification; there is an exercise of section 7805(b) relief by the Commissioner; and the elimination or reduction is made only to the extent necessary to enable the plan to continue to satisfy the requirements for qualified plans. In general, the elimination or reduction of a section 411(d)(6) protected benefit will not be treated as necessary if it is possible through other modifications to the plan (e.g., by expanding the availability of an optional form of benefit to additional employees) to satisfy the applicable qualification requirement.

(ii) Joint and survivor annuity. A plan that provides a range of three or more actuarially equivalent joint and survivor annuity options may be amended to eliminate any of such options, other than the options with the largest and smallest optional survivor payment percentages, even if the effect of such amendment is to change which of the options is the qualified joint and survivor annuity under section 417. Thus, for example, if a money purchase pension plan provides three joint and survivor annuity options with survivor payments of 50%, 75% and 100%, respectively, that are uniform with respect to age and are actuarially equivalent, then the employer may eliminate the option with the 75% survivor payment, even if this option had been the qualified joint and survivor annuity under the plan.

(iii) In-kind distributions—(A) In-kind distributions payable under defined contribution plans in the form of marketable securities other than employer securities. If a defined contribution plan includes an optional form of benefit under which benefits are distributed in the form of marketable securities, other than securities of the employer, that optional form of benefit may be modified by a plan amendment that substitutes cash for the marketable securities as the medium of distribution. For purposes of this paragraph (b)(2)(iii)(A) and paragraph (b)(2)(iii)(B) of this Q&A-2, the term marketable securities means marketable securities as defined in section 731(c)(2), and the term securities of the employer means securities of the employer as defined in section 402(e)(4)(E)(ii).

(B) Amendments to defined contribution plans to specify medium of distribution. If a defined contribution plan includes an optional form of benefit under which benefits are distributable to a participant in a medium other than cash, the plan may be amended to limit the types of property in which distributions may be made to the participant to the types of property specified in the amendment. For this purpose, the types of property specified in the amendment must include all types of property (other than marketable securities that are not securities of the employer) that are allocated to the participant's account on the effective date of the amendment and in which the participant would be able to receive a distribution immediately before the effective date of the amendment if a distributable event occurred. In addition, a plan amendment may provide that the participant's right to receive a distribution in the form of specified types of property is limited to the property allocated to the participant's account at the time of distribution that consists of property of those specified types.

(C) In-kind distributions after plan termination. If a plan includes an optional form of benefit under which benefits are distributed in specified property, that optional form of benefit may be modified for distributions after plan termination by substituting cash for the specified property as the medium of distribution to the extent that, on plan termination, an employee has the opportunity to receive the optional form of benefit in the form of the specified property. This exception is not available, however, if the employer that maintains the terminating plan also maintains another plan that provides an optional form of benefit under which benefits are distributed in the specified property.

(D) Examples. The following examples illustrate the application of this paragraph (b)(2)(iii):

(iv) Coordination with diversification requirement. A tax credit employee stock ownership plan (as defined in section 409(a)) or an employee stock ownership plan (as defined in section 4975(e)(7)) may be amended to provide that a distribution is not available in employer securities to the extent that an employee elects to diversify benefits pursuant to section 401(a)(28).

(v) Involuntary distributions. A plan may be amended to provide for the involuntary distribution of an employee's benefit to the extent such involuntary distribution is permitted under sections 411(a)(11) and 417(e). Thus, for example, an involuntary distribution provision may be amended to require that an employee who terminates from employment with the employer receive a single sum distribution in the event that the present value of the employee's benefit is not more than $3,500, by substituting the cash-out limit in effect under § 1.411(a)-11(c)(3)(ii) for $3,500, without violating section 411(d)(6). In addition, for example, the employer may amend the plan to reduce the involuntary distribution threshold from the cash-out limit in effect under § 1.411(a)-11(c)(3)(ii) to any lower amount and to eliminate the involuntary single sum option for employees with benefits between the cash-out limit in effect under § 1.411(a)-11(c)(3)(ii) and such lower amount without violating section 411(d)(6). This rule does not permit a plan provision permitting employer discretion with respect to optional forms of benefit for employees the present value of whose benefit is less than the cash-out limit in effect under § 1.411(a)-11(c)(3)(ii).

(vi) Distribution exception for certain profit-sharing plans—(A) In general. If a defined contribution plan that is not subject to section 412 and does not provide for an annuity option is terminated, the plan may be amended to provide for the distribution of a participant's accrued benefit upon termination in a single sum optional form without the participant's consent. The preceding sentence does not apply if the employer maintains any other defined contribution plan (other than an employee stock ownership plan as defined in section 4975(e)(7)).

(B) Examples. The provisions of this paragraph (b)(2)(vi) can be illustrated by the following examples:

(vii) Distribution of benefits on default of loans. Notwithstanding that the distribution of benefits arising from an execution on an account balance used to secure a loan on which there has been a default is an optional form of benefit, a plan may be amended to eliminate or change a provision for loans, even if such loans would be secured by an employee's account balance.

(viii) Provisions for transfer of benefits between and among defined contribution plans and defined benefit plans. A plan may be amended to eliminate provisions permitting the transfer of benefits between and among defined contribution plans and defined benefit plans.

(ix) De minimis change in the timing of an optional form of benefit. A plan may be amended to modify an optional form of benefit by changing the timing of the availability of such optional form if, after the change, the optional form is available at a time that is within two months of the time such optional form was available before the amendment. To the extent the optional form of benefit is available prior to termination of employment, six months may be substituted for two months in the prior sentence. Thus, for example, a plan that makes in-service distributions available to employees once every month may be amended to make such in-service distributions available only once every six months. This exception to section 411(d)(6) relates only to the timing of the availability of the optional form of benefit. Other aspects of an optional form of benefit may not be modified and the value of such optional form may not be reduced merely because of an amendment permitted by this exception.

(x) Amendment of hardship distribution standards. A qualified cash or deferred arrangement that permits hardship distributions under § 1.401(k)-1(d)(3) may be amended to specify or modify nondiscriminatory and objective standards for determining the existence of an immediate and heavy financial need, the amount necessary to meet the need, or other conditions relating to eligibility to receive a hardship distribution. For example, a plan will not be treated as violating section 411(d)(6) merely because it is amended to specify or modify the resources an employee must exhaust to qualify for a hardship distribution or to require employees to provide additional statements or representations to establish the existence of a hardship. A qualified cash or deferred arrangement may also be amended to eliminate hardship distributions. The provisions of this paragraph also apply to profit-sharing or stock bonus plans that permit hardship distributions, whether or not the hardship distributions are limited to those described in § 1.401(k)-1(d)(3).

(xi) Section 415 benefit limitations. Accrued benefits under a plan as of the first day of the first limitation year beginning after December 31, 1986, that exceed the benefit limitations under section 415 (b) or (e), effective on the first day of the plan's first limitation year beginning after December 31, 1986, because of a change in the terms and conditions of the plan made after May 5, 1986, or the establishment of a plan after that date, may be reduced to the level permitted under section 415 (b) or (e).

(xii) Prohibited payment option under single-employer defined benefit plan of plan sponsor in bankruptcy. A single-employer plan that is covered under section 4021 of the Employee Retirement Income Security Act of 1974, Public Law 93-406 (88 Stat. 829 (1974)), as amended (ERISA), may be amended, effective for a plan amendment that is both adopted and effective after November 8, 2012, to eliminate an optional form of benefit that includes a prohibited payment described in section 436(d)(5), provided that the following conditions are satisfied on the applicable amendment date (as defined in § 1.411(d)-3(g)(4)):

(A) The enrolled actuary of the plan has certified that the plan's adjusted funding target attainment percentage (as defined in section 436(j)(2)) for the plan year that contains the applicable amendment date is less than 100 percent.

(B) The plan is not permitted to pay any prohibited payment, due to application of the requirements of section 436(d)(2) of the Internal Revenue Code and section 206(g)(3)(B) of ERISA, because the plan sponsor is a debtor in a bankruptcy case (that is, a case under title 11, United States Code, or under similar Federal or State law).

(C) The court overseeing the bankruptcy case has issued an order, after notice to the affected parties (as defined in section 4001(a)(21) of ERISA) and a hearing, within the meaning of 11 U.S.C. 102(1), finding that the adoption of the amendment eliminating that optional form of benefit is necessary to avoid a distress termination of the plan pursuant to section 4041(c) of ERISA or an involuntary termination of the plan pursuant to section 4042 of ERISA before the plan sponsor emerges from bankruptcy (or before the bankruptcy case is otherwise completed).

(D) The Pension Benefit Guaranty Corporation has issued a determination that—

(1) The adoption of the amendment eliminating that optional form of benefit is necessary to avoid a distress or involuntary termination of the plan before the plan sponsor emerges from bankruptcy (or before the bankruptcy case is otherwise completed); and

(2) The plan is not sufficient for guaranteed benefits within the meaning of section 4041(d)(2) of ERISA.

(c) Multiple amendments—(1) General rule. A plan amendment violates the requirements of section 411(d)(6) if it is one of a series of plan amendments that, when taken together, have the effect of reducing or eliminating a section 411(d)(6) protected benefit in a manner that would be prohibited by section 411(d)(6) if accomplished through a single amendment.

(2) Determination of time period for combining plan amendments. For purposes of paragraph (c)(1) of this Q&A-2, generally only plan amendments adopted within a 3-year period are taken into account. But see Q&A-1(c)(1) of this section for rules relating to repeated plan amendments.

(d) ESOP and stock bonus plan exception—(1) In general. Subject to the limitations in paragraph (d)(2) of this Q&A-2, a tax credit employee stock ownership plan (as defined in section 409(a)) or an employee stock ownership plan (as defined in section 4975(e)(7)) will not be treated as violating the requirements of section 411(d)(6) merely because of any of the circumstances described in paragraphs (d)(1)(i) through (d)(1)(iv) of this Q&A-2. In addition, a stock bonus plan that is not an employee stock ownership plan will not be treated as violating the requirements of section 411(d)(6) merely because of any of the circumstances described in paragraphs (d)(1)(ii) and (d)(1)(iv) of this Q&A-2.

(i) Single sum or installment optional forms of benefit. The employer eliminates, or retains the discretion to eliminate, with respect to all participants, a single sum optional form or installment optional form with respect to benefits that are subject to section 409(h)(1)(B), provided such elimination or retention of discretion is consistent with the distribution and payment requirements otherwise applicable to such plans (e.g., those required by section 409).

(ii) Employer becomes substantially employee-owned or is an S corporation. The employer eliminates, or retains the discretion to eliminate, with respect to all participants, optional forms of benefit by substituting cash distributions for distributions in the form of employer stock with respect to benefits subject to section 409(h) in the circumstances described in paragraph (d)(1)(ii)(A) or (B) of this Q&A-2, but only if the employer otherwise meets the requirements of section 409(h)(2)—

(A) The employer becomes substantially employee-owned; or

(B) For taxable years of the employer beginning after December 31, 1997, the employer is an S corporation as defined in section 1361.

(iii) Employer securities become readily tradable. The employer eliminates, or retains the discretion to eliminate, with respect to all participants, in cases in which the employer securities become readily tradable, optional forms of benefit by substituting distributions in the form of employer securities for distributions in cash with respect to benefits that are subject to section 409(h).

(iv) Employer securities cease to be readily tradable or certain sales. The employer eliminates, or retains the discretion to eliminate, with respect to all participants, optional forms of benefit by substituting cash distributions for distributions in the form of employer stock with respect to benefits that are subject to section 409(h) in the following circumstances:

(A) The employer stock ceases to be readily tradable;

(B) The employer stock continues to be readily tradable but there is a sale of substantially all of the stock of the employer or a sale of substantially all of the assets of a trade or business of the employer and, in either situation, the purchasing employer continues to maintain the plan.

(2) Limitations on ESOP and stock bonus plan exceptions—(i) Nondiscrimination requirement. Plan amendments and the retention and exercise of discretion permitted under the exceptions in paragraph (d)(1) must meet the nondiscrimination requirements of section 401(a)(4).

(ii) ESOP investment requirement. Except as provided in paragraph (d)(2)(iii) of this Q&A-2, benefits provided by employee stock ownership plans will not be eligible for the exceptions in paragraph (d)(1) of this Q&A-2 unless the benefits have been held in a tax credit employee stock ownership plan (as defined in section 409 (a)) or an employee stock ownership plan (as defined in section 4975 (e)(7)) subject to section 409 (h) for the five-year period prior to the exercise of employer discretion or any amendment affecting such benefits and permitted under paragraph (d)(1) of this Q&A-2. For purposes of the preceding sentence, if benefits held under an employee stock ownership plan are transferred to a plan that is an employee stock ownership plan at the time of transfer, then the consecutive periods under the transferor and transferee employee stock ownership plans may be aggregated for purposes of meeting the five-year requirement. If the benefits are held in an employee stock ownership plan throughout the entire period of their existence, and such total period of existence is less than five years, then such lesser period may be substituted for the five year requirement.

(3) Effective date. The provisions of this paragraph (d) are effective beginning with the first day of the first plan year commencing on or after January 1, 1989. Prior to this effective date the reduction or elimination of a section 411(d)(6) protected benefit by a tax credit employee stock ownership plan (as defined in section 409(a)) or an employee stock ownership plan (as defined in section 4975(e)(7)) will not be treated as violating the requirements of section 411(d)(6) if such reduction or elimination reflects a reasonable interpretation of the statutory language of section 411(d)(6)(C).

(4) Additional exceptions and requirements. The Commissioner may, in revenue rulings, notices or other documents of general applicability, prescribe such additional rules and exceptions, consistent with the purposes of this section, as may be necessary or appropriate.

(e) Permitted plan amendments affecting alternative forms of payment under defined contribution plans—(1) General rule. A defined contribution plan does not violate the requirements of section 411(d)(6) merely because the plan is amended to eliminate or restrict the ability of a participant to receive payment of accrued benefits under a particular optional form of benefit for distributions with annuity starting dates after the date the amendment is adopted if, after the plan amendment is effective with respect to the participant, the alternative forms of payment available to the participant include payment in a single-sum distribution form that is otherwise identical to the optional form of benefit that is being eliminated or restricted.

(2) Otherwise identical single-sum distribution. For purposes of this paragraph (e), a single-sum distribution form is otherwise identical to an optional form of benefit that is eliminated or restricted pursuant to paragraph (e)(1) of this Q&A-2 only if the single-sum distribution form is identical in all respects to the eliminated or restricted optional form of benefit (or would be identical except that it provides greater rights to the participant) except with respect to the timing of payments after commencement. For example, a single-sum distribution form is not otherwise identical to a specified installment form of benefit if the single-sum distribution form is not available for distribution on the date on which the installment form would have been available for commencement, is not available in the same medium of distribution as the installment form, or imposes any condition of eligibility that did not apply to the installment form. However, an otherwise identical distribution form need not retain rights or features of the optional form of benefit that is eliminated or restricted to the extent that those rights or features would not be protected from elimination or restriction under section 411(d)(6) or this section.

(3) Example. The following example illustrates the application of this paragraph (e):

(4) Effective date. This paragraph (e) is applicable on January 25, 2005.

Q-3 Does the transfer of benefits between and among defined benefit plans and defined contribution plans (or similar transactions) violate the requirements of section 411(d)(6)?

A-3 (a) Transfers and similar transactions—(1) General rule. Section 411(d)(6) protected benefits may not be eliminated by reason of transfer or any transaction amending or having the effect of amending a plan or plans to transfer benefits. Thus, for example, except as otherwise provided in this section, an employer who maintains a money purchase pension plan that provides for a single sum optional form of benefit may not establish another plan that does not provide for this optional form of benefit and transfer participants' account balances to such new plan.

(2) Defined benefit feature and separate account feature. The defined benefit feature of an employee's benefit under a defined benefit plan and the separate account feature of an employee's benefit under a defined contribution plan are section 411(d)(6) protected benefits. Thus, for example, the elimination of the defined benefit feature of an employee's benefit under a defined benefit plan, through transfer of benefits from a defined benefit plan to a defined contribution plan or plans, will violate section 411(d)(6).

(3) Waiver prohibition. In general, except as provided in paragraph (b) of this Q&A-3, a participant may not elect to waive section 411(d)(6) protected benefits. Thus, for example, the elimination of the defined benefit feature of a participant's benefit under a defined benefit plan by reason of a transfer of such benefits to a defined contribution plan pursuant to a participant election, at a time when the benefit is not distributable to the participant, violates section 411(d)(6).

(4) Direct rollovers. A direct rollover described in Q&A-3 of § 1.401(a)(31)-1 that is paid to a qualified plan is not a transfer of assets and liabilities that must satisfy the requirements of section 414(l), and is not a transfer of benefits for purposes of applying the requirements under section 411(d)(6) and paragraph (a)(1) of this Q&A-3. Therefore, for example, if such a direct rollover is made to another qualified plan, the receiving plan is not required to provide, with respect to amounts paid to it in a direct rollover, the same optional forms of benefit that were provided under the plan that made the direct rollover. See § 1.401(a)(31)-1, Q&A-14.

(b) Elective transfers of benefits between defined contribution plans—(1) General rule. A transfer of a participant's entire benefit between qualified defined contribution plans (other than any direct rollover described in Q&A-3 of § 1.401(a)(31)-1) that results in the elimination or reduction of section 411(d)(6) protected benefits does not violate section 411(d)(6) if the following requirements are met—

(i) Voluntary election. The plan from which the benefits are transferred must provide that the transfer is conditioned upon a voluntary, fully-informed election by the participant to transfer the participant's entire benefit to the other qualified defined contribution plan. As an alternative to the transfer, the participant must be offered the opportunity to retain the participant's section 411(d)(6) protected benefits under the plan (or, if the plan is terminating, to receive any optional form of benefit for which the participant is eligible under the plan as required by section 411(d)(6)).

(ii) Types of plans to which transfers may be made. To the extent the benefits are transferred from a money purchase pension plan, the transferee plan must be a money purchase pension plan. To the extent the benefits being transferred are part of a qualified cash or deferred arrangement under section 401(k), the benefits must be transferred to a qualified cash or deferred arrangement under section 401(k). To the extent the benefits being transferred are part of an employee stock ownership plan as defined in section 4975(e)(7), the benefits must be transferred to another employee stock ownership plan. Benefits transferred from a profit-sharing plan other than from a qualified cash or deferred arrangement, or from a stock bonus plan other than an employee stock ownership plan, may be transferred to any type of defined contribution plan.

(iii) Circumstances under which transfers may be made. The transfer must be made either in connection with an asset or stock acquisition, merger, or other similar transaction involving a change in employer of the employees of a trade or business (i.e., an acquisition or disposition within the meaning of § 1.410(b)-2(f)) or in connection with the participant's change in employment status to an employment status with respect to which the participant is not entitled to additional allocations under the transferor plan.

(2) Applicable qualification requirements. A transfer described in this paragraph (b) is a transfer of assets or liabilities within the meaning of section 414(l)(1) and, thus, must satisfy the requirements of section 414(l). In addition, this paragraph (b) only provides relief under section 411(d)(6); a transfer described in this paragraph must satisfy all other applicable qualification requirements. Thus, for example, if the survivor annuity requirements of sections 401(a)(11) and 417 apply to the plan from which the benefits are transferred, as described in this paragraph (b), but do not otherwise apply to the receiving plan, the requirements of sections 401(a)(11) and 417 must be met with respect to the transferred benefits under the receiving plan. In addition, the vesting provisions under the receiving plan must satisfy the requirements of section 411(a)(10) with respect to the amounts transferred.

(3) Status of elective transfer as other right or feature. A right to a transfer of benefits from a plan pursuant to the elective transfer rules of this paragraph (b) is an other right or feature within the meaning of § 1.401(a)(4)-4(e)(3), the availability of which is subject to the nondiscrimination requirements of section 401(a)(4) and § 1.401(a)(4)-4. However, for purposes of applying the rules of § 1.401(a)(4)-4, the following conditions are to be disregarded in determining the employees to whom the other right or feature is available—

(i) A condition restricting the availability of the transfer to benefits of participants who are transferred to a different employer in connection with a specified asset or stock disposition, merger, or other similar transaction involving a change in employer of the employees of a trade or business (i.e., a disposition within the meaning of § 1.410(b)-2(f)), or in connection with any such disposition, merger, or other similar transaction.

(ii) A condition restricting the availability of the transfer to benefits of participants who have a change in employment status to an employment status with respect to which the participant is not entitled to additional allocations under the transferor plan.

(c) Elective transfers of certain distributable benefits between qualified plans—(1) In general. A transfer of a participant's benefits between qualified plans that results in the elimination or reduction of section 411(d)(6) protected benefits does not violate section 411(d)(6) if—

(i) The transfer occurs at a time at which the participant's benefits are distributable (within the meaning of paragraph (c)(3) of this Q&A-3);

(ii) For a transfer that occurs on or after January 1, 2002, the transfer occurs at a time at which the participant is not eligible to receive an immediate distribution of the participant's entire nonforfeitable accrued benefit in a single-sum distribution that would consist entirely of an eligible rollover distribution within the meaning of section 401(a)(31)(C);

(iii) The voluntary election requirements of paragraph (b)(1)(i) of this Q&A-3 are met;

(iv) The participant is fully vested in the transferred benefit in the transferee plan;

(v) In the case of a transfer from a defined contribution plan to a defined benefit plan, the defined benefit plan provides a minimum benefit, for each participant whose benefits are transferred, equal to the benefit, expressed as an annuity payable at normal retirement age, that is derived solely on the basis of the amount transferred with respect to such participant; and

(vi) The amount of the benefit transferred, together with the amount of any contemporaneous section 401(a)(31) direct rollover to the transferee plan, equals the entire nonforfeitable accrued benefit under the transferor plan of the participant whose benefit is being transferred, calculated to be at least the greater of the single-sum distribution provided for under the plan for which the participant is eligible (if any) or the present value of the participant's accrued benefit payable at normal retirement age (calculated by using interest and mortality assumptions that satisfy the requirements of section 417(e) and subject to the limitations imposed by section 415).

(2) Treatment of transfer—(i) In general. A transfer of benefits pursuant to this paragraph (c) generally is treated as a distribution for purposes of section 401(a). For example, the transfer is subject to the cash-out rules of section 411(a)(7), the early termination requirements of section 411(d)(2), and the survivor annuity requirements of sections 401(a)(11) and 417. A transfer pursuant to the elective transfer rules of this paragraph (c) is not treated as a distribution for purposes of the minimum distribution requirements of section 401(a)(9).

(ii) Status of elective transfer as optional form of benefit. A right to a transfer of benefits from a plan pursuant to the elective transfer rules of this paragraph (c) is an optional form of benefit under section 411(d)(6), the availability of which is subject to the nondiscrimination requirements of section 401(a)(4) and § 1.401(a)(4)-4.

(3) Distributable benefits. For purposes of paragraph (c)(1)(i) of this Q&A-3, a participant's benefits are distributable on a particular date if, on that date, the participant is eligible, under the terms of the plan from which the benefits are transferred, to receive an immediate distribution of these benefits (e.g., in the form of an immediately commencing annuity) from that plan under provisions of the plan not inconsistent with section 401(a).

(d) Effective date. This Q&A-3 is applicable for transfers made on or after September 6, 2000.

Q-4: May a plan provide that the employer may, through the exercise of discretion, deny a participant a section 411(d)(6) protected benefit for which the participant is otherwise eligible?

A-4: (a) In general. Except as provided in paragraph (d) of Q&A-2 of this section with respect to certain employee stock ownership plans, a plan that permits the employer, either directly or indirectly, through the exercise of discretion, to deny a participant a section 411(d)(6) protected benefit provided under the plan for which the participant is otherwise eligible (but for the employer's exercise of discretion) violates the requirements of section 411(d)(6). A plan provision that makes a section 411(d)(6) protected benefit available only to those employees as the employer may designate is within the scope of this prohibition. Thus, for example, a plan provision under which only employees who are designated by the employer are eligible to receive a subsidized early retirement benefit constitutes an impermissible provision under section 411(d)(6). In addition, a pension plan that permits employer discretion to deny the availability of a section 411(d)(6) protected benefit violates the definitely determinable requirement of section 401(a), including section 401(a)(25). See § 1.401-1(b)(1)(i). This is the result even if the plan specifically limits the employer's discretion to choosing among section 411(d)(6) protected benefits, including optional forms of benefit, that are actuarially equivalent. In addition, the provisions of sections 411(a)(11) and 417(e) that allow a plan to make involuntary distributions of certain amounts are not excepted from this limitation on employer discretion. Thus, for example, a plan may not permit employer discretion with respect to whether benefits will be distributed involuntarily in the event that the present value of the employee's benefit is not more than the cash-out limit in effect under § 1.411(a)-11(c)(3)(ii) within the meaning of sections 411(a)(11) and 417(e). (An exception is provided for such provisions with respect to the nondiscrimination requirements of section 401(a)(4). See § 1.401(a)(4)-4(b)(2)(ii)(C).)

(b) Exception for administrative discretion. A plan may permit limited discretion with respect to the ministerial or mechanical administration of the plan, including the application of objective plan criteria specifically set forth in the plan. Such plan provisions do not violate the requirements of section 411(d)(6) or the definitely determinable requirement of section 401(a), including section 401(a)(25). For example, these requirements are not violated by the following provisions that permit limited administrative discretion:

(1) Commencement of benefit payments as soon as administratively feasible after a stated date or event;

(2) Employer authority to determine whether objective criteria specified in the plan (e.g., objective criteria designed to identify those employees with a heavy and immediate financial need or objective criteria designed to determine whether an employee has a permanent and total disability) have been satisfied; and

(3) Employer authority to determine, pursuant to specific guidelines set forth in the plan, whether the participant or spouse is dead or cannot be located.

Q-5: When will the exercise of discretion by some person or persons, other than the employer, be treated as employer discretion?

A-5: For purposes of applying the rules of this section and § 1.401(a)-4, the term “employer” includes plan administrator, fiduciary, trustee, actuary, independent third party, and other persons. Thus, if a plan permits any person, other than the participant (and other than the participant's spouse), the discretion to deny or limit the availability of a section 411(d)(6) protected benefit for which the employee is otherwise eligible under the plan (but for the exercise of such discretion), such plan violates the requirements of sections 401(a), including section 411(d)(6) and, where applicable, the definitely determinable requirement of section 401(a), including section 401(a)(25).

Q-6: May a plan condition the availability of a section 411(d)(6) protected benefit on the satisfaction of objective conditions that are specifically set forth in the plan?

A-6: (a) Certain objective conditions permissible—(1) In general. The availability of a section 411(d)(6) protected benefit may be limited to employees who satisfy certain objective conditions provided the conditions are ascertainable, clearly set forth in the plan and not subject to the employer's discretion except to the extent reasonably necessary to determine whether the objective conditions have been met. Also, the availability of the section 411(d)(6) protected benefit must meet the nondiscrimination requirements of section 401(a)(4). See § 1.401(a)-4.

(2) Examples of permissible conditions. The following examples illustrate of permissible objective conditions: a plan may deny a single sum distribution form to employees for whom life insurance is not available at standard rates as defined under the terms of the plan at the time the single sum distribution would otherwise be payable; a plan may provide that a single sum distribution is available only if the employee is in extreme financial need as defined under the terms of the plan at the time the single sum distribution would otherwise be payable; a plan my condition the availability of a single sum distribution on the execution of a covenant not to compete, provided that objective conditions with respect to the terms of such covenant and the employees and circumstances requiring execution of such covenant are set forth in the plan.

(b) Conditions based on factors within employer's discretion generally impermissible. A plan may not limit the availability of section 411(d)(6) protected benefits permitted under the plan on objective conditions that are within the employer's discretion. For example, the availability of section 411(d)(6) protected benefits in a plan may not be conditioned on a determination with respect to the level of the plan's funded status, because the amount of plan funding is within the employer's discretion. However, for example, although conditions based on the plan's funded status are impermissible, a plan may limit the availability of a section 411(d)(6) protected benefit (e.g., a single sum distribution) in an objective manner, such as the following:

(1) Single sum distributions of $25,000 and less are available without limit; and

(2) Single sum distributions in excess of $25,000 are available for a year only to the extent that the total amount of such single sum distributions for the year is not greater than $5,000,000; and

(3) An objective and nondiscriminatory method for determining which particular single sum distributions will not be available during a year in order for the $5,000,000 limit to be satisfied is set forth in the plan.

Q-7: May a plan be amended to add employer discretion or conditions restricting the availability of a section 411(d)(6) protected benefit?

A-7: No. The addition of employer discretion or objective conditions with respect to a section 411(d)(6) protected benefit that has already accrued violates section 411(d)(6). Also, the addition of conditions (whether or not objective) or any change to existing conditions with respect to section 411(d)(6) protected benefits that results in any further restriction violates section 411(d)(6). However, the addition of objective conditions to a section 411(d)(6) protected benefit may be made with respect to benefits accrued after the later of the adoption or effective date of the amendment. In addition, objective conditions may be imposed on section 411(d)(6) protected benefits accrued as of the date of an amendment where permitted under the transitional rules of § 1.401(a)-4 Q&A-5 and Q&A-8 of this section. Finally, objective conditions may be imposed on section 411(d)(6) protected benefits to the extent permitted by the permissible benefit cutback provisions of Q&A-2 of this section.

Q-8: If a plan contains an impermissible employer discretion provision with respect to a section 411(d)(6) protected benefit, what acceptable alternative exist for amending the plan without violating the requirements of section 411(d)(6)?

A-8: (a) In general. The following rules apply for purposes of making necessary amendments to existing plans (as defined in Q&A-9 of this section) that contain discretion provisions with respect to the availability of section 411(d)(6) protected benefits that violate the requirements of section 401(a), including sections 401(a)(25) and 411(d)(6), and this section. These transitional rules are provided under the authority of section 411(d)(6) and section 7805(b).

(b) Transitional alternatives. If the availability of an optional forms of benefit, early or late retirement benefit, or retirement-type subsidy under an existing plan is conditioned on the exercise of employer discretion, the plan must be amended either to eliminate the optional form of benefit, early or late retirement benefit, or retirement-type subsidy to make such benefit available to all participants without limitation, or to apply objective and nondiscriminatory conditions to the availability of the optional form of benefit, early or later retirement benefit, or retirement-type subsidy. See paragraph (d) of this Q&A-8 for rules limiting the period during which section 411(d)(6) protected benefits may be eliminated or reduced under this paragraph.

(c) Compliance and amendment date provisions—(1) Operational compliance requirement. On or before the applicable effective date for the plan (as determined under Q&A-9 of this section), the plan sponsor must select one of the alternatives permitted under paragraph (b) of the Q&A-8 with respect to each affected section 411(d)(6) protected benefit and the plan must be operated in accordance with this selection. This is an operational requirement and does not require a plan amendment prior to the period set forth in paragraph (c)(2) of this Q&A-8. There are no special reporting requirements under the Code or this section with respect to this selection.

(2) Deferred amendment date. If paragraph (c)(1) of this Q&A-8 is satisfied, a plan amendment conforming the plan to the particular alternative selected under paragraph (b) of this Q&A-8 must be adopted within the time period permitted for amending plans in order to meet the requirements of section 410(b) as amended by TRA '86. The plan amendment to conform the plan to these regulations may be made at an earlier date. Such conforming amendment must be consistent with the sponsor's selection as reflected by plan practice during the period from the effective date to the date the amendment is adopted. Thus, for example, if any existing calendar year noncollectively bargained defined benefit plan has a single sum distribution option that is subject to employer discretion as of August 1, 1986, and such employer makes one or more single sum distributions available on or after January 1, 1989 and before the effective date by which plan amendment is required pursuant to this section, then such employer may not adopt a plan amendment eliminating the single sum distribution, but rather must adopt an amendment eliminating the discretion provision. Any objective conditions that are adopted as part of such amendment must not be inconsistent with the plan practice for the applicable period prior to the amendment. A conforming amendment under this paragraph (c)(2) must be made with respect to each section 411(d)(6) protected benefit for which such amendment is required and must be retroactive to the applicable effective date.

(d) Limitation on transitional alternatives. The transitional alternatives permitting the elimination or reduction of section 411(d)(6) protected benefits are only permissible until the applicable effective date for the plan (see Q&A-9 of this section). After the applicable effective date, any amendment (other than one permitted under paragraph (c)(2) of this Q&A-8) that eliminates or reduces a section 411(d)(6) protected benefit or imposes new objective conditions on the availability of such benefit will fail to qualify for the exception to section 411(d)(6) provided in this Q&A-8. This is the case without regard to whether the section 411(d)(6) protected benefit is subject to employer discretion.

Q-9: What are the applicable effective date rules for purposes of this section?

A-9: (a) General effective date. Except as otherwise provided in this section, the provisions of this section are effective January 30, 1986.

(b) New plans—(1) In general. Unless otherwise provided in paragraph (b)(2) of this Q&A-9, plans that are either adopted or made effective on or after August 1, 1986, are “new plans”. With respect to such new plans, this section is effective August 1, 1986. This effective date is applicable to such plans whether or not they are collectively bargained.

(2) Exception with respect to certain new plans. Plans that are new plans as defined in paragraph (b)(1) of this Q&A-9; under which the availability of a section 411(d)(6) protected benefit is subject to employer discretion; and that receive a favorable determination letter that covered such plan provisions with respect to an application submitted prior to July 11, 1988, will be treated as existing plans with respect to such section 411(d)(6) protected benefit for purposes of the transitional rules of this section. Thus, such plans are eligible for the compliance and amendment alternatives set forth in the transitional rule in Q&A-8 of this section.

(c) Existing plans—(1) In general. Plans, including plans that are adoptions of master or prototype plans, that are both adopted and in effect prior to August 1, 1986, are “existing plans” for purposes of this section. In addition, a plan that is established after July 31, 1986, but before January 1, 1989, as an initial adoption of a master or prototype plan for which a favorable opinion letter was issued by the Service after July 18, 1985 and before January 1, 1989, will be deemed to be an existing plan for purposes of this section. See sections 4.01 and 4.02 of Rev. Proc. 84-23, 1984-1 C.B. 457, 459, for the definitions of master prototype plans. However, if such plan ceases to be covered under an opinion letter of the type described above, as a result of amendment of the plan or adoption of a new plan, prior to the first day of the first plan year beginning on or after January 1, 1989, then the effective date for such plan will be determined as though the plan were a new plan initially adopted as of the date of such amendment or adoption of a new plan. Finally, new plans described in paragraph (b)(2) of this Q&A-9 are treated as existing plans with respect to certain section 411(d)(6) protected benefits. Subject to the limitations in paragraph (c) of this Q&A-9, the effective dates set forth in paragraphs (c)(2), (c)(3), and (c)(4) of this Q&A-9 apply to these existing plans for purposes of this section:

(2) Existing noncollectively bargained plans. With respect to existing plans other than collectively bargained plans this section is effective for the first day of the first plan year commencing on or after January 1, 1989.

(3) Existing collectively bargained plans. With respect to existing collectively bargained plans this section is effective for the later of the first day of the first plan year commencing on or after January 1, 1989, or the first day of the first plan year that the requirements of section 410(b) as amended by TRA '86 apply to such plan.

(4) Existing master and prototype plans. With respect to existing plans that are adoptions of master or prototype plans the effective date will be the first day of the first plan year commencing on or after January 1, 1989.

(d) Delayed effective date not applicable to new alternatives or conditions—(1) In general. The delayed effective dates in paragraphs (c)(2) and (c)(3) of this Q&A-9 for existing plans are only applicable with respect to a section 411(d)(6) protected benefit if both the section 411(d)(6) protected benefit and the condition providing employer discretion as to the availability of such benefit are both adopted and in effect prior to August 1, 1986. If the preceding sentence is not satisfied with respect to a particular section 411(d)(6) protected benefit, this section is effective with respect to such section 411(d)(6) protected benefit as if the plan were a new plan.

(2) Addition of discretion on or after January 30, 1986. The delayed effective dates in paragraphs (c)(2) and (c)(3) of this Q&A-9 are not available with respect to any section 411(d)(6) protected benefit if the section 411(d)(6) protected benefit was provided for in the plan prior to January 30, 1986, and the availability of such benefit was made subject to the exercise of employer discretion on or after January 30, 1986. If the conditions set forth in this paragraph are not satisfied with respect to a particular section 411(d)(6) protected benefit, this section is effective with respect to such section 411(d)(6) protected benefit as if the plan were a new plan. A limited exception is provided with respect to existing plans that provided a particular section 411(d)(6) protected benefit prior to January 30, 1986, and then amended the plan after January 30, 1986, and before August 1, 1986, to add a provision for employer discretion with respect to the availability of such benefit. Such plans are required to have been amended retroactively by December 31, 1987, to remove such provision for employer discretion, and, if the benefit made subject to such discretion was subsequently eliminated, the plan is required to have been further amended, by the same date, to retroactively reinstate the benefit.

(3) Exception for certain amendments covered by a favorable determination letter. If an amendment adding a section 411(d)(6) protected benefit subject to employer discretion was adopted or made effective after August 1, 1986, and the plan receives a favorable determination letter covering such provision with respect to an application for such letter made prior to July 11, 1988, then the effective date for purposes of amending such provision under the transitional rules is the applicable effective date determined under the rules with respect to existing plans.

(e) Transitional rule effective date. The transitional rule provided in Q&A-8 of this section is effective January 30, 1986.

Q-10: If a plan provides for an age 70 1/2 distribution option that commences prior to retirement from employment with the employer maintaining the plan, to what extent may the plan be amended to eliminate this distribution option?

A-10: (a) In general. The right to commence benefit distributions in a particular form and at a particular time prior to retirement from employment with the employer maintaining the plan is a separate optional form of benefit within the meaning of section 411(d)(6)(B) and Q&A-1 of this section, even if the plan provision creating this right was included in the plan solely to comply with section 401(a)(9), as in effect for years before January 1, 1997. Therefore, except as otherwise provided in paragraph (b) of this Q&A-10 or any other Q&A in this section, a plan amendment violates section 411(d)(6) if it eliminates an age 70 1/2 distribution option (within the meaning of paragraph (c) of this Q&A-10) to the extent that it applies to benefits accrued as of the later of the adoption date or effective date of the amendment.

(b) Permitted elimination of age 70 1/2 distribution option. An amendment of a plan will not violate the requirements of section 411(d)(6) merely because the amendment eliminates an age 70 1/2 distribution option to the extent that the option provides for distribution to an employee prior to retirement from employment with the employer maintaining the plan, provided that—

(1) The amendment eliminating this optional form of benefit applies only to benefits with respect to employees who attain age 70 1/2 in or after a calendar year, specified in the amendment, that begins after the later of—

(i) December 31, 1998; or

(ii) The adoption date of the amendment;

(2) The plan does not, except to the extent required by section 401(a)(9), preclude an employee who retires after the calendar year in which the employee attains age 70 1/2 from receiving benefits in any of the same optional forms of benefit (except for the difference in the timing of the commencement of payments) that would have been available had the employee retired in the calendar year in which the employee attained age 70 1/2; and

(3) The amendment is adopted no later than—

(i) The last day of the remedial amendment period that applies to the plan for changes under the Small Business Job Protection Act of 1996 (110 Stat. 1755); or

(ii) Solely in the case of a plan maintained pursuant to one or more collective bargaining agreements between employee representatives and one or more employers ratified before September 3, 1998, the last day of the twelfth month beginning after the date on which the last of such collective bargaining agreements terminates (determined without regard to any extension thereof on or after September 3, 1998), if later than the date described in paragraph (b)(3)(i) of this Q&A-10. For purposes of this paragraph (b)(3)(ii), the rules of § 1.410(b)-10(a)(2) apply for purposes of determining whether a plan is maintained pursuant to one or more collective bargaining agreements, except that September 3, 1998 is substituted for March 1, 1986, as the date before which the collective bargaining agreements must be ratified.

(c) Age 70 1/2 distribution option. For purposes of this Q&A-10, an age 70 1/2 distribution option is an optional form of benefit under which benefits payable in a particular distribution form (including any modifications that may be elected after benefit commencement) commence at a time during the period that begins on or after January 1 of the calendar year in which an employee attains age 70 1/2 and ends April 1 of the immediately following calendar year.

(d) Examples. The provisions of this Q&A-10 are illustrated by the following examples:

(e) Effective date. This Q&A-10 applies to amendments adopted and effective after June 5, 1998.

Q-11: To what extent may a plan amendment that is made pursuant to the Taxpayer Relief Act of 1997 (TRA '97) (Public Law 105-34, 111 Stat. 788), reduce or eliminate section 411(d)(6) protected benefits?

A-11: A plan amendment does not violate the requirements of section 411(d)(6) merely because the plan amendment reduces or eliminates section 411(d)(6) protected benefits as of the effective date of the plan amendment, provided that—

(a) The plan amendment is made pursuant to an amendment made by title XV, or subtitle H of title X, of TRA '97; and

(b) The plan amendment is adopted no later than the last day of any remedial amendment period that applies to the plan pursuant to §§ 1.401(b)-1 and 1.401(b)-1T for changes under TRA '97.

Q-12. Is there a transition period during which a plan is permitted to eliminate a right to in-service distributions in connection with an amendment to ensure that the plan's normal retirement age satisfies the requirements of § 1.401(a)-1(b)(2)?

A-12. (a) In general. A plan amendment that changes the normal retirement age under the plan to a later normal retirement age pursuant to § 1.401(a)-1(b)(2) does not violate section 411(d)(6) merely because it eliminates a right to an in-service distribution prior to the amended normal retirement age. However, this paragraph does not provide relief from any other applicable requirements; for example, this relief does not permit the amendment to violate section 411(a)(9) (requiring that the normal retirement benefit not be less than the greater of any early retirement benefit payable under the plan or the benefit under the plan commencing at normal retirement age), section 411(a)(10) (if the amendment changes the plan's vesting rules), section 411(d)(6) (other than elimination of the right to an in-service distribution prior to the amended normal retirement age), or section 4980F (relating to an amendment that reduces the rate of future benefit accrual). This paragraph only applies to a plan amendment that is adopted after May 22, 2007 and on or before the last day of the applicable remedial amendment period under § 1.401(b)-1 with respect to the requirements of § 1.401(a)-1(b)(2) and (3).

(b) Example. The following example illustrates the application of this section:

(a) Experience gain treatment. Dividends, rate credits, and credits for forfeitures arising in a plan described in paragraph (b) of this section are experience gains described in section 412(b)(3)(B)(ii) (relating to the amortization of experience gains).

(b) Plan. A plan is described in this paragraph (b) if—

(1) The plan is funded solely through a group deferred annuity contract,

(2) The annual single premium required under the contract for the purchase of the benefits accruing during the plan year is treated as the normal cost of the plan for that year, and

(3) The amount necessary to pay in equal annual installments, over the appropriate amortization period, an amount equal to the single premium necessary to provide all past service benefits not initially funded, together with interest thereon, is treated as the annual amortization amount determined under section 412(b)(2)(B) (i), (ii) or (iii).

(c) Effective date. This section applies for the first plan year to which section 412 applies that begins after May 22, 1981.

(a) Actuarial cost method and funding method. Section 3 (31) of the Employee Retirement Income Security Act of 1974 (“ERISA”) provides certain acceptable (and unacceptable) actuarial cost methods which may (or may not) be used by employee plans. The term “funding method” when used in section 412 has the same meaning as the term “actuarial cost method” in section 3 (31) of ERISA. For shortfall method for certain collectively bargained plans, see § 1.412(c)(1)-2; for principles applicable to funding methods in general, see regulations under section 412(c)(3).

(b) Computations included in funding method. The funding method of a plan includes not only the overall funding method used by the plan but also each specific method of computation used in applying the overall method. However, the choice of which actuarial assumptions are appropriate to the overall method or to the specific method of computation is not a part of the funding method. For example, the decision to use or not to use a mortality factor in the funding method of a plan is not a part of such funding method. Similarly, the specific mortality rate determined to be applicable to a particular plan year is not part of the funding method. See section 412(c)(5) for the requirement of approval to change the funding method used by a plan.

(a) In general—(1) Shortfall method. The shortfall method is a funding method that adapts a plan's underlying funding method for purposes of section 412. As such, the use of the shortfall method is subject to section 412(c)(3). A plan described in paragraph (a)(2) of this section may elect to determine the charges to the funding standard account required by section 412(b) under the shortfall method. These charges are computed on the basis of an estimated number of units of service or production (for which a certain amount per unit is to be charged). The difference between the net amount charged under this method and the net amount that otherwise would have been charged under section 412 for the same period is a shortfall loss (gain) and is to be amortized over certain subsequent plan years.

(2) Eligibility for use of shortfall. No plan may use the shortfall method unless—

(i) The plan is a collectively bargained plan described in section 413(a), and

(ii) Contributions to the plan are made at a rate specified under the terms of a legally binding agreement applicable to the plan.

(b) Computation and effect of net shortfall charge—(1) In general. The “net shortfall charge” to the funding standard account under the shortfall method is the product of (i) the estimated unit charge described in paragraph (c) of this section that applies for a particular plan year, multiplied by (ii) the actual number of base units (for example, units of service or production) which occurred during that plan year. When the shortfall method is used, the net shortfall charge is a substitute for the specific charges and credits to the funding standard account described in section 412 (b)(2) and (3)(B).

(2) Example. Paragraph (b)(1) of this section may be illustrated by the following example:

(3) Plans with more than one contract, contribution rate, employer, or benefit level—(i) General rule. A single plan with more than one contract, contribution rate, employer, or benefit level may compute a separate net shortfall charge for each contract, contribution rate, each employer, or each benefit level. The sum of these charges is the plan's total net shortfall charge. under § 1.412(c)(1)-1(b), the use of separate computations would be a specific method of computation used in applying the overall funding method. See also paragraph (f)(5) of this section.

(ii) Single valuation. Only one actuarial valuation shall be made for the single plan on each actuarial valuation date.

(iii) Reasonableness test. The specific method of computation of the net shortfall charge must be reasonable, determined in the light of the facts and circumstances.

(c) Estimated unit charge. The estimated unit charge is the annual computation charge described in paragraph (d) of this section divided by the estimated base units of service or production described in paragraph (e) of this section.

(d) Annual computation charge. The annual computation charge for a plan year is the sum of the following amounts:

(1) The net charges and credits which, but for using the shortfall method, would be made under section 412 (b)(2) and (b)(3)(B).

(2) The amount described in paragraph (g)(3) of this section, if applicable, for amortization of shortfall gain or loss.

(e) Estimated base units—(1) In general. The estimated base units are the expected units of service or production for a plan year (hours, days, tons, dollars of compensation, etc.), determined as of the base unit estimation date for that plan year under paragraph (f) of this section. This estimate must be based on the past experience of the plan and the reasonable expectations of the plan for the plan year. The specific type of unit used must be described in the statement of funding method for the plan year. (See paragraph (i)(3) of this section for reporting requirements.)

(2) Reasonable expectations. The reasonableness of expectations used under paragraph (e)(1) of this section is determined under the facts and circumstances of the plan for each plan year as of the relevant base unit estimation date. Expectations will be considered unreasonable if, for example, they do not reflect a consistent and substantial decline or growth in actual base units that has occurred over the course of recent years and that is likely to continue beyond the base unit estimation date. This determination of reasonableness is independent of determinations made under section 412(c)(3) of the reasonableness of actuarial assumptions.

(f) Base unit estimation date—(1) In general. The base unit estimation date for the current plan year is determined under this paragraph (f). This date shall be an actuarial valuation date no earlier than the last actuarial valuation date occurring at least one year before the earliest date any current collectively bargained agreement in existence during the plan year came into effect.

(2) Four-month rule. For purposes of this paragraph (f), a current collectively bargained agreement is one in effect during at least four months of the current plan year.

(3) Effective date of agreement. For purposes of this paragraph (f), a collectively bargained agreement shall be deemed to have come into effect on the effective date of the agreement containing the currently effective provision for contributions to the plan or the benefits provided under the plan.

(4) Long-term contract rule. The effective date of a collectively bargained agreement shall be deemed not to occur prior to the first day of the third plan year preceding the current year.

(5) Special rule for plans computing separate net shortfall charge. A plan that computes a separate net shortfall charge for each contract, contribution rate, employer, or benefit level under paragraph (b)(3) of this section shall determine the base unit estimation date for each separate charge without regard to any collectively bargained agreement that does not relate to that contract, contribution rate, employer, or benefit level. If a collective bargaining agreement requiring contributions by a certain employer, or prescribing a certain benefit level, is in effect on December 31, 1980, the preceding sentence shall not apply to the computation of a separate net shortfall charge for that employer or benefit level until the earlier of—

(i) The first plan year beginning after the date on which expires the collective bargaining agreement requiring contributions by that employer (or the last collective bargaining agreement relating to that benefit level), or

(ii) The first plan year beginning after December 31, 1983.

(6) Example. The rules contained in paragraph (f) of this section are illustrated by the following table. In the table, “V” signifies actuarial valuation date (January 1 in each case shown); “B” signifies beginning of a contract; and “E” signifies end of a contract. The table shows the resulting earliest base unit estimation date with respect to the following assumed items:

(g) Amortization of shortfall gain or loss—(1) Definition. The shortfall gain for a plan is the excess for the plan year of—

(i) The net shortfall charge computed under paragraph (b) of this section over

(ii) The annual computation charge described in paragraph (d) of this section.

(2) Shortfall amortization period—(i) First year. The plan year in which the amortization of a shortfall gain or loss must begin is the earlier of two years: the fifth plan year following the plan year in which the shortfall gain or loss arose, or the first plan year beginning after the latest scheduled expiration date of a collectively bargained agreement in effect with respect to the plan during the plan year in which the shortfall gain or loss arose. For purposes of this subparagraph, a contract expiring on the last day of a plan year shall be deemed to be renewed on such last day for the same period of years as the contract that succeeds the expiring contract.

(ii) Last year. The plan year in which the amortization of a shortfall gain or loss must end is the 15th plan year following the plan year in which the shortfall gain or loss arose. For a multiemployer plan described in section 414(f), the amortization must end with the 20th plan year instead of the 15th.

(3) Annual amortization amount. The shortfall gain or loss must be amortized in equal annual installments. The total amount to be amortized must be adjusted for interest at the rate used for determining the plan's normal cost.

(4) Shortfall gain or loss under spread gain type of funding method—(i) In general. A spread gain type of funding method spreads experience gains and losses over future periods as part of a plan's normal cost. (Examples of spread gain types of funding methods are the aggregate cost method, the frozen initial liability method, and the attained age normal method.) However, a shortfall gain or loss is not an experience gain or loss. Therefore, a plan using a spread gain type of funding method together with the shortfall method must amortize shortfall gains and losses and otherwise meet the requirements of paragraph (g) of this section.

(ii) Asset adjustment for aggregate method. A plan using the shortfall method with the aggregate cost method of funding must adjust its plan assets for a shortfall gain or loss in calculating normal cost. The unamortized portion of any shortfall gain is subtracted from plan assets. The unamortized portion of any shortfall loss is added to plan assets.

(5) Reconciliation of shortfall gain or loss with funding standard account. At the beginning of each year, the actual unfunded liability under the method used by the plan must equal the outstanding balance of all amortization bases, including bases for shortfall gains and losses, less the credit balance under the funding standard account at the end of the prior year.

(6) Example. This paragraph is illustrated by the following examples:

(h) Amortization of experience gain or loss—(1) General rule. In the case of a plan using an immediate gain type of funding method, an experience gain or loss shall be amortized pursuant to section 412 (b)(2)(B)(iv) or (b)(3)(B)(ii). (Examples of the immediate gain type of funding method are the unit credit method, the entry age normal cost method, and the individual level premium cost method.) For purposes of this section, a shortfall gain or loss is not an experience gain or loss. The amount of the experience gain or loss must be adjusted for interest at the rate used for determining the plan's normal cost.

(2) Experience amortization period under shortfall method—(i) First year. The plan year in which the amortization of an experience gain or loss must begin in the case of a plan using the shortfall method is the earlier of two years: the fifth plan year following the plan year in which the experience gain or loss arose, or the first plan year beginning after the last scheduled expiration date of a contract in effect during the plan year in which the experience gain or loss arose. For purposes of this subparagraph a contract expiring on the last day of the plan year shall be deemed to be renewed on such last day for the same period of years as the contract that succeeds the expiring contract.

(ii) Last year. The plan year in which the amortization of an experience gain or loss must end in the case of a plan using the shortfall method is the 15th plan year following the plan year in which the experience gain or loss arose. For a multi-employer plan described in section 414 (f), the amortization must end with the 20th plan year instead of the 15th.

(3) Use of annual computation charge in determining experience gain or loss. In the case of a plan using an immediate gain type of funding method, an experience gain or loss is the difference between the expected unfunded liability and the actual unfunded liability under the plan. The expected unfunded liability as of the end of a plan year equals the actual unfunded liability as of the beginning of the year plus normal cost, minus contributions, all adjusted for interest. If the plan adopts the shortfall method, the expected unfunded liability is computed by using the normal cost applicable for the plan year in determining the annual computation charge under paragraph (d) of this section. The same normal cost is used in computing the unfunded liability under the frozen initial liability funding method.

(4) Example. This paragraph is illustrated by the following example:

(i) Election procedure—(1) In general. To elect the shortfall method, a collectively bargained plan must attach a statement to the annual report required under section 6058 (a) for the first plan year to which it is applied. The statement shall state that the shortfall method is adopted, beginning with the plan year covered by such report. Advance approval from the Internal Revenue Service is not required if the shortfall method is first adopted on or before the later of—

(i) The first plan year to which section 412 applies or

(ii) The last plan year commencing before December 31, 1981.

(2) Use of specific computation method. A specific method of computation under the shortfall method is described in paragraph (b)(3) of this section, regarding the treatment of more than one contract, employer, or benefit level under the plan. This specific method may be adopted with respect to any plan year to which the shortfall method applies. Approval from the Commissioner must be received under section 412(c)(5) prior to the adoption of this specific computation method for a plan year subsequent to the first plan year to which the shortfall method applies, or prior to the discontinuance of a specific computation method, once adopted.

(3) Reporting requirements. Each annual report required by section 6058(a) and periodic report of the actuary required by section 6059 must include all additional information relevant to the use of the shortfall method as may be required by the applicable forms and the instructions for such forms.

(j) Transitional rule. In lieu of paragraphs (g)(2) and (h)(2) of this section relating to the amortization period for shortfall and experience gains and losses, for gains and losses arising in plan years beginning before January 1, 1981, a plan may rely on the prior published position of the Internal Revenue Service with respect to the amortization period for shortfall and experience gains and losses.

(k) Supersession. This section and § 1.412 (c) (1)-1 supersede §§ 11.412 (c) (1)-1 and (c) (1)-2 of the Temporary Income Tax Regulations Under the Employee Retirement Income Security Act of 1974.

(a) In general—(1) Restoration method. The restoration method is a funding method that adapts the underlying funding method of section 412 in the case of certain plans that are or have been terminated and are later restored by the Pension Benefit Guaranty Corporation (PBGC). The normal operation of the funding standard account, and all other provisions of section 412 and the regulations thereunder, are unchanged except as provided in this § 1.412(c)(1)-3. Under the restoration method, the PBGC shall determine a restoration payment schedule, extending over no more than 30 years, that replaces all charges and credits to the funding standard account attributable to pre-restoration amortization bases. The restoration payment schedule is determined on the basis of an actuarial valuation of the accrued liability of the plan on the initial post-restoration valuation date less the actuarial value of the plan assets on that date. The initial post-restoration valuation date is the date of the valuation that falls in the first plan year beginning on or after the date of the restoration order.

(2) Applicability of restoration method. A plan must use the restoration method if, and only if—

(i) The plan is being or has been terminated pursuant to section 4041(c) or section 4042 of the Employee Retirement Income Security Act of 1974 (ERISA); and

(ii) The plan has been restored by the PBGC pursuant to its authority under section 4047 of ERISA.

(b) Computation and effect of the initial restoration amortization base—(1) In general. The initial restoration amortization base is determined under the underlying funding method used by the plan. When the plan uses a spread gain funding method that does not maintain an unfunded liability, the plan must change either to an immediate gain method that directly calculates an accrued liability or to a spread gain method that maintains an unfunded liability. A plan may adopt any cost method that satisfies this requirement and that is acceptable under section 412 and the regulations thereunder, provided that the plan administrator follows the procedures established by the Commissioner for changes in funding methods. The initial restoration amortization base is determined using the valuation for the plan year in which the initial post-restoration valuation date falls. The initial restoration amortization base equals the accrued liability with respect to plan benefit liabilities returned by the PBGC less the value of the plan assets returned by the PBGC. The initial restoration amortization base replaces all prior amortization bases including those under section 412(b)(2) (B), (C), and (D) and under section 412(b)(3)(B). Any base resulting from a change in funding method, including a change required under this paragraph, is treated as a prior amortization base within the meaning of this paragraph (b). Any accumulated funding deficiency or credit balance in the funding standard account is set equal to zero when the initial restoration amortization base is established.

(2) Example. The following example illustrates the provisions of this paragraph (b):

(c) Establishment of a restoration payment schedule—(1) Certification requirement. When the PBGC establishes a restoration payment schedule, the Executive Director of the PBGC must certify to the PBGC's Board of Directors, and to the Internal Revenue Service, that the PBGC has reviewed the funding of the plan, the financial condition of the plan sponsor and its controlled group members, the payments required under the restoration payment schedule (taking into account the availability of deferrals authorized under paragraph (c)(4) of this section), and any other factor that the PBGC deems relevant, and, based on that review, determines that it is in the best interests of participants and beneficiaries of the plan and the pension insurance program that the restored plan not be reterminated.

(2) Requirements for restoration payment schedule—(i) Amortization of base over period of no more than 30 years. The restoration payment schedule must be prescribed in an order requiring the employer to make stated contributions to the plan sufficient to amortize the initial restoration amortization base over a period extending not more than 30 years after the initial post-restoration valuation date (the restoration payment period). Payments included in the restoration payment schedule order are charged to the funding standard account of the plan at the end of each plan year in accordance with paragraph (d) of this section. The restoration payment schedule must provide for total charges that are sufficient to amortize the entire amount of the initial restoration amortization base by the end of the restoration payment period. The scheduled charges need not be in level amounts, but the present value of the prescribed charges on the initial post-restoration valuation date, computed with interest at the valuation rate, must equal the initial restoration amortization base.

(ii) Minimum annual charge. The restoration payment schedule must prescribe annual charges that are sufficient to prevent the outstanding balance of the initial restoration amortization base from exceeding whichever of the following amounts is applicable—

(A) During the first 10 plan years on the restoration payment schedule, the amount of the initial restoration amortization base on the date the base was established; or

(B) During plan years 11 through 20 on the restoration payment schedule, the maximum permitted outstanding balance of the initial restoration amortization base at the end of the tenth plan year, as calculated under paragraph (c)(2)(iii) of this section; or

(C) During plan years 21 through the end of the restoration payment schedule, the maximum permitted outstanding balance of the initial restoration amortization base at the end of the twentieth plan year, as calculated under paragraph (c)(2)(iii) of this section.

(iii) Interim amortization requirements. The restoration payment schedule must provide for sufficient periodic charges so that the outstanding balance of the initial restoration amortization base at the end of the tenth plan year and at the end of the twentieth plan year of the restoration payment period will not be larger than the outstanding balance that would have remained at the end of the tenth plan year and at the end of the twentieth plan year, respectively, if the initial restoration amortization base had been amortized in level annual amounts over the restoration payment period at the valuation rate.

(3) Amendments to the restoration payment schedule. The order establishing the restoration payment schedule may be amended by the PBGC from time to time with respect to any remaining payments, provided that no amendment may extend the restoration payment period beyond 30 years from the initial post-restoration valuation date, and provided further that the restoration payment schedule, as amended, satisfies the requirements of paragraph (c)(2) of this section.

(4) Deferral of minimum scheduled annual payment amounts—(i) Authority to grant deferral. Not later than 2 1/2 months following the end of the plan year, the PBGC may grant a deferral of the charges required in the restoration payment schedule for that plan year if the requirements in paragraph (c)(4)(ii) of this section are satisfied. The PBGC may require the plan sponsor and its controlled group members to provide security to the plan as a condition to granting a deferral.

(ii) Determination of business hardship. Before granting a deferral under this paragraph (c)(4), the PBGC must make a determination that the granting of the deferral is in the best interests of plan participants and the plan termination insurance system, and that the plan sponsor and its controlled group members are unable to make the scheduled restoration payments without experiencing temporary substantial business hardship. In making these determinations, the factors the PBGC shall consider, include, but are not limited to, the following—

(A) Whether the plan sponsor and its controlled group members are operating at an economic loss;

(B) Whether there is substantial unemployment or underemployment in the trades or businesses of the plan sponsor and its controlled group members;

(C) Whether the sales and profits of the industry or industries are depressed or declining; and

(D) Whether it is reasonable to expect that the plan termination insurance system will suffer a greater loss if the plan is terminated than if it is continued as a restored plan.

(iii) Amount of deferral. The amount of the deferral for any particular plan year may not exceed the lesser of the amount that would have been required to be contributed under the restoration payment schedule for that year or interest at the valuation rate on the outstanding balance of the initial restoration amortization base for that year. An amortization payment for a deferral granted for a prior plan year may not be deferred. No deferral may extend the overall restoration payment period beyond 30 years.

(iv) Modification of payment schedule. The restoration payment schedule must be adjusted to reflect any deferral granted for a plan year in the manner prescribed in this paragraph (c). The charge otherwise specified in the schedule is reduced by the amount of any deferral. The charges under the restoration payment schedule for the subsequent plan years are increased by the amounts in paragraph (c)(4)(v) of this section.

(v) Amortization of deferred amount. The amount of any deferral granted by the PBGC for any plan year must be amortized in level amounts over five years or such shorter period as may be prescribed by the PBGC, at the valuation rate, beginning with the plan year following the year of the deferral.

(vi) Number of deferrals permitted. The PBGC may not grant more than five deferrals of the minimum scheduled payments as required by this section during the restoration payment period and no more than three of these deferrals may be granted during the first ten years of that period.

(vii) Deferrals override minimum annual charges and interim amortization requirements. In determining the minimum annual charge under paragraph (c)(2)(ii) of this section and in applying the interim amortization requirements of paragraph (c)(2)(iii) of this section, the unamortized balances of any deferrals granted by the PBGC under this paragraph shall be added to the outstanding balance of the initial restoration amortization base otherwise allowable.

(d) Charging the scheduled restoration payments to the funding standard account. In addition to any other charges and credits prescribed in the normal operation of the funding standard account under section 412, the amount of each payment specified in the restoration payment schedule shall be charged against the funding standard account of the plan for the plan year to which that payment is attributed in the restoration payment schedule. To the extent that the restoration payment schedule provides for payments before the end of the plan year, the annual charge to the funding standard account attributable to the restoration payment schedule is equal to the sum of the periodic payments for the plan year accumulated with interest at the valuation rate to the last day of the plan year.

(e) Changes in actuarial assumptions or methods. The plan administrator must notify the PBGC of any changes in the actuarial assumptions or methods used by the plan. Upon notification of any such change, the PBGC may make any changes to the restoration payment schedule that it deems appropriate.

(f) Change to restoration method. A plan that has been restored must use the restoration method until the initial restoration amortization base has been fully amortized. The use of this method does not require prior approval from the Commissioner. A plan using the restoration method must compute the charges to the funding standard account to amortize the initial restoration amortization base in accordance with the order of the PBGC and in accordance with this section.

(g) Deficit reduction contribution—(1) Calculation of deficit reduction contribution. For any plan using the restoration method, the deficit reduction contribution under section 412(l)(2) is equal to the sum of—

(i) The unfunded section 412(l) restoration liability amount; plus

(ii) The unfunded new liability amount.

(2) Unfunded section 412(l) restoration liability amount. The unfunded section 412(l) restoration liability amount is the amount necessary to amortize fully the unfunded section 412(l) restoration liability in installments, as prescribed by the PBGC, over not more than 30 years. The annual amount need not be level, but at all times the present value of the future amortization charges prescribed under the restoration payment schedule, at the current liability interest rate, must equal the outstanding balance of the unfunded section 412(l) restoration liability and the schedule must provide that at the end of no more than 30 years the entire amount of the unfunded section 412(l) restoration liability base will have been fully amortized. The schedule prescribed for amortization of the unfunded section 412(l) restoration liability must comply with the requirements imposed in paragraph (c) of this section on the restoration payment schedule, except as provided in paragraph (g)(7) of this section and except that the maximum permitted outstanding balance of the unfunded section 412(l) restoration liability at the end of the tenth plan year must not be greater than the outstanding balance of the section 412(l) restoration liability that would have remained at the end of the tenth plan year if the unfunded section 412(l) restoration liability had been amortized in level amounts over the restoration payment period at the actual current liability interest rate for each year, increased by the current liability interest rate differential as defined under paragraph (g)(7) of this section. The unfunded section 412(l) restoration liability amount for the tenth plan year otherwise prescribed under the restoration payment schedule is increased by any outstanding current liability interest rate differential. By issuing an appropriate order, the PBGC may permit the outstanding current liability interest rate differential to be amortized over the tenth through the fourteenth plan years. If the PBGC permits the amortization of the outstanding current liability interest rate differential, then the unfunded section 412(l) restoration liability amount for each year to which an amortization payment is attributed under the order shall be increased by such payment. The outstanding balance otherwise required by paragraph (g)(2) of this section is increased by the outstanding balance, if any, of the base resulting from the amortization of the current liability interest rate differential. The PBGC may amend the amortization schedule for the unfunded section 412(l) restoration liability subject to the limits on amendments to the amortization schedule prescribed for the initial restoration amortization base.

(3) Establishment of unfunded section 412(l) restoration liability. In the plan year in which the initial post-restoration valuation date falls, the unfunded section 412(l) restoration liability is equal to the unfunded current liability of the plan.

(4) Unfunded new liability amount. In the case of a plan using the restoration method, the unfunded new liability amount is the applicable percentage, as defined in section 412(l)(4)(C), of the unfunded new liability determined under paragraph (g)(5) of this section.

(5) Unfunded new liability. The unfunded new liability of a plan using the restoration method is the excess, if any, of the unfunded current liability of the plan, within the meaning of section 412(l)(8)(A) for the plan year (determined without taking into account any unpredictable contingent event benefits, even if the event has occurred) over the outstanding balance of the unfunded section 412(l) restoration liability determined under paragraph (g)(3) of this section.

(6) Offset of amortization charges. The amounts charged to the funding standard account pursuant to the restoration payment schedule in order to amortize the initial restoration base, as described in paragraph (d) of this section, must be offset against the deficit reduction contribution in paragraph (g)(1) of this section along with any other applicable amounts provided in section 412(l)(1)(A)(ii).

(7) Interest rate differential. During the first 10 plan years after the initial post-restoration valuation date, the restoration payment schedule must prescribe an unfunded section 412(l) restoration liability amount for each plan year that is sufficient to prevent the outstanding balance of the unfunded section 412(l) restoration liability from exceeding the initial amount of the unfunded section 412(l) restoration liability increased by the current liability interest rate differential. The current liability interest rate differential at any point during the first ten years of the restoration payment period is the excess, if any, of the outstanding balance of the unfunded section 412(l) restoration liability determined using the actual current liability interest rate for each year, taking into account the charges described in paragraph (d) of this section, over the outstanding balance of the unfunded section 412(l) restoration liability determined using the lowest, for each year, of the initial current liability interest rate, the current liability interest rate for the computation year, and the valuation interest rate, taking into account the charges described in paragraph (d) of this section.

(h) Election of the alternative minimum funding standard. A plan using the restoration method may not elect the alternative minimum funding standard under section 412(g).

(i) Funding review by the PBGC. The PBGC must review the funding of any plan using the restoration method at least once in each plan year. As a result of a funding review, the PBGC may amend the restoration payment schedule as provided in paragraph (c)(3) of this section. As part of the funding review, the Executive Director of the PBGC must certify to the PBGC's Board of Directors, and to the Internal Revenue Service, that the PBGC has reviewed the funding of the plan, the financial condition of the plan sponsor and its controlled group members, the payments required under the restoration payment schedule (taking into account the availability of deferrals authorized under paragraph (c)(4) of this section), and any other factor that the PBGC deems relevant, and, based on that review, determines that it is in the best interests of participants and beneficiaries of the plan and the pension insurance program that the restored plan not be reterminated.

(a) Introduction—(1) In general. This section prescribes rules for valuing plan assets under an actuarial valuation method which satisfies the requirements of section 412(c)(2)(A). An actuarial valuation method is a funding method within the meaning of section 412(c)(3) and the regulations thereunder. Therefore, certain changes affecting the actuarial valuation method are identified in this section as changes in a plan's funding method.

(2) Exception for certain bonds, etc. The rules of this section do not apply to bonds or other evidences of indebtedness for which the election described in section 412(c)(2)(B) has been made, nor are such assets counted in applying paragraphs (b) or (c) of this section. Also, an election under section 412(c)(2)(B) is not a change in funding method within the meaning of section 412(c)(5).

(3) Money purchase pension plan. A money purchase pension plan must value assets for the purpose of satisfying the requirements of section 412(c)(2)(A) solely on the basis of their fair market value (under paragraph (c) of this section).

(4) Defined benefit plans. (i) To satisfy the requirements of section 412(c)(2)(A), an actuarial method valuing assets of a defined benefit plan must meet the requirements of paragraph (b) of this section.

(ii) In general, the purpose of paragraph (b) of this section is to permit use of reasonble actuarial valuation methods designed to mitigate short-run changes in the fair market value of plan assets. The funding of plan benefits and the charges and credits to the funding standard account required by section 412 are generally based upon the assumption that the defined benefit plan will be continued by the employer. Thus, short-run changes in the value of plan assets presumably will offset one another in the long term. Accordingly, in the determination of the amount required to be contributed under section 412 it is generally not necessary to recognize fully each change in fair market value of the assets in the period in which it occurs.

(iii) The asset valuation rules contained in paragraph (b) produce a “smoothing” effect. Thus, investment performance, including appreciation or depreciation in the market value of the assets occurring in each plan year, may be recognized gradually over several plan years. This “smoothing” is in addition to the “smoothing” effect which results, for example, from amortizing experience losses and gains over 15 or 20 years under section 412(b)(2 (B)(iv) and (3)(B)(ii).

(b) Asset valuation method requirements—(1) Consistent basis. (i) The actuarial asset valuation method must be applied on a consistent basis. Any change in meeting the requirements of this paragraph (b) is a change in funding method subject to section 412(c)(5).

(ii) A method may satisfy the consistency requirement even though computations are based only on the period elapsed since the adoption of the method or on asset values occurring during that period.

(2) Statement of plan's method. The method of determining the actuarial value (but not fair market value) of the assets must be specified in the plan's actuarial report (required under section 6059). The method must be described in sufficient detail so that another actuary employing the method described would arrive at a reasonably similar result. Whether a deviation from the stated actuarial valuation method is a change in funding method is to be determined in accordance with section 412(c)(5) and the regulations thereunder. A deviation to include a type of asset not previously held by the plan would not be a change in funding method.

(3) Consistent valuation dates. The same day or days (such as the first or the last day of a plan year) must be used for all purposes to value the plan's assets for each plan year, or portion of plan year, for which a valuation is made. For purposes of this section, each such day is a valuation date. A change in the day or days used is a change in funding method.

(4) Reflect fair market value. The valuation method must take into account fair market value by making use of the—

(i) Fair market value (determined under paragraph (c) of this section), or

(ii) Average value (determined under paragraph (b)(7) of this section) of the plan's assets as of the applicable asset valuation date. This is done either directly in the computation of their actuarial value or indirectly in the computation of upper or lower limits placed on that value.

(5) Results above and below fair market or average value. A method will not satisfy the requirements of this paragraph (b) if it is designed to produce a result which will be consistently above or below the values described in paragraph (b)(4) (i) and (ii). However, a method designed to produce a result which consistently falls between fair market value and average value will satisfy this requirement. See Example 5 in paragraph (b)(9) of this section for an illustration of a method described in the preceding sentence.

(6) Corridor limits. (i) Regardless of how the method reflects fair market value under paragraph (b)(4), the method must result in an actuarial value of the plan's assets which is not less than a minimum amount and not more than a maximum amount. The minimum amount is the lesser of 80 percent of the current fair market value of plan assets as of the applicable asset valuation date or 85 percent of the average value (as described in subparagraph (7)) of plan assets as of that date. The maximum amount is the greater of 120 percent of the current fair market value of plan assets as of the applicable asset valuation date or 115 percent of the average value of plan assets as of that date.

(ii) Under a plan's method, a preliminary computation of the expected actuarial value may fall outside the prescribed corridor. A method meets the requirements of paragraph (b)(6)(i) of this section is such a case only by adjusting the expected actuarial value to the nearest corridor limit applicable under the method. A plan may use an actuarial valuation method with a narrower corridor than the general corridor required under paragraph (b)(6)(i). The adjustment to the nearest corridor limit of such a method for purposes of this subdivision (ii) would be determined by the narrower corridor stated in the description of the plan's method.

(7) Average value. the average value of plan assets is computed by—

(i) Determining the fair market value of plan assets at least annually,

(ii) Adding the current fair market value of the assets (as of the applicable valuation date) and their adjusted values (as described in paragraph (b)(8) of this section) for a stated period not to exceed the five most recent plan years (including the current year), and

(iii) Dividing this sum by the number of values (including the current fair market value) considered in computing the sum described in subdivision (ii).

(8) Adjusted value. (i) the adjusted value of plan assets for a prior valuation date is their fair market value on that date with certain positive and negative adjustments. These adjustments reflect changes that occur between the prior asset valuation date and the current valuation date. However, no adjustment is made for increases or decreases in the total value of plan assets that result from the purchase, sale, or exchange of plan assets or from the receipt of payment on a debt obligation held by the plan.

(ii) In determining the adjusted value of plan assets for a prior valuation date, there is added to the fair market value of the plan assets of that date the sum of all additions to the plan assets since that date, excluding appreciation in the fair market value of the assets. The additions would include, for example, any contribution to the plan; any interest or dividend paid to the plan; and any asset not taken into account in a prior valuation of assets, but taken into account for the current year, in computing the fair market value of plan assets under paragraph (c) of this section.

(iii) In determining the adjusted value of plan assets for a prior valuation date, there is subtracted from the fair market value of the plan assets on that date the sum of all reductions in plan assets since that date, excluding depreciation in the fair market value of the assets. The reductions would include, for example, any benefit paid from plan assets; any expense paid from plan assets; and any asset taken into account in a prior valuation of assets but not taken into account for the current year, in computing the fair market value of plan assets under paragraph (c) of this section.

(9) Examples. This paragraph (b) may be illustrated by the following examples. In each example, assume that the pension plan uses a consistent actuarial method of valuing its assets within the meaning of paragraph (b)(1), (2), and (3) of this section.

(c) Fair market value of assets—(1) General rules. Except as otherwise provided in this paragraph (c), the fair market value of a plan's assets for purposes of this section is the price at which the property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of relevant facts.

(d) Methods for taking into account the fair market value of certain agreements. [Reserved]

(e) Effective date and transition rules—(1) Effective date. This section applies to plan years to which section 412, or section 302 of the Employee Retirement Income Security Act of 1974, applies.

(2) Special rule for certain plan years. For plan years beginning prior to November 12, 1980, the amounts required to be determined under section 412 may be computed on the basis of any reasonable actuarial method of asset valuation which takes into account the fair market value of the plan's assets, even if the method does not meet all of the requirements of paragraphs (a) through (c) of this section.

(3) Plan years beginning on or after November 12, 1980. Paragraphs (a) through (c) of this section apply beginning with the first valuation of plan assets made for a plan year to which section 412 applies that begins on or after November 12, 1980. The statement of the plan's actuarial asset valuation method required by paragraph (b)(2) of this section must be included with the plan's actuarial report for that year, in addition to any subsequent reports.

(4) Effect of change of asset valuation method. A plan which is required to change its asset valuation method to comply with paragraphs (a) through (c) of this section must make the change no later than the time when the plan is first required to comply with this section under paragraph (e)(3). A method of adjustment must be used to take account of any difference in the actuarial value of the plan's assets based on the old and new valuation methods. The plan may use either—

(i) A method of adjustment described in paragraph (e)(5) or (e)(6) of this section without prior approval by the Commissioner, or

(ii) Any other method of adjustment if the Commissioner gives prior approval under section 412(c)(5).

(5) Retroactive recomputation method. (i) Under this method of adjustment, the plan recomputes the balance of the funding standard account as of the beginning of the first plan year for which it uses its new asset valuation method to comply with paragraphs (a) through (c) of this section. This new balance is recomputed by retroactively applying the plan's new method as of the first day of the first plan year to which section 412 applies.

(ii) Beginning with the first plan year for which it uses its new method, the plan computes the normal cost and amortization charges and credits to the funding standard account based on the retroactive application of its new method as of the first day of the first plan year to which section 412 applies.

(iii) If the recomputed aggregate charges exceed the recomputed aggregate credits to the funding standard account as of the end of the first plan year for which the plan uses its new method, an additional contribution to the plan may be necessary to avoid an accumulated funding deficiency in that year. The use of the retroactive recomputation method may also result in an accumulated funding deficiency for years prior to that first year. In such cases, the rules of section 412(c)(10), relating to the time when certain contributions are deemed to have been made, apply.

(6) Prospective gain or loss adjustment method. (i) Under this method of adjustment the plan values its assets under its new method no later than the valuation date for the first plan year beginning after [the publication date of this section]

(ii) Regardless of the type of funding method used by a plan, the difference in the value of the assets under the old and the new asset valuation methods may be treated as arising from an experience loss or gain; or alternatively it may be treated as arising from a change in actuarial assumptions.

(iii) The treatment of this difference as an experience gain or loss or as a change in actuarial assumptions must be consistent with the treatment of such gains, losses, or changes under the funding method used by the plan. Thus, if a plan uses a spread gain type funding method other than the aggregate cost method, the difference in the value of assets under the old and the new asset valuation methods may be either amortized or spread over future periods as a part of normal cost. Examples of this type of funding method are the frozen initial liability cost method and the attained age normal cost method. With an aggregate method, the difference in the value of assets under the old and the new asset valuation methods must be spread over future periods as a part of normal cost.

(a) Introduction—(1) In general. This section prescribes rules for determining whether or not, in the case of an ongoing plan, a funding method is reasonable for purposes of section 412(c)(3). A method is unreasonable only if it is found to be inconsistent with a rule prescribed in this section. The term “reasonable funding method” under this section has the same meaning as the term “acceptable actuarial cost method” under section 3(31) of the Employee Retirement Income Security Act of 1974 (ERISA).

(2) Computations included in method. See § 1.412(c)(1)-1(b) for a discussion of matters that are, and are not, included in the funding method of a plan.

(3) Plans using shortfall. The shortfall method is a method of determining charges to the funding standard account by adapting the underlying funding method of certain collectively bargained plans in the manner described in § 1.412(c)(1)-2. As such, the shortfall method is a funding method. The underlying method of a plan that uses the shortfall method must be a reasonable funding method under this section. The rules contained in this section, relating to cost under a reasonable funding method, apply in the shortfall method to the annual computation charge under § 1.412(c)(1)-2(d).

(4) Scope of funding method. Except for the shortfall method, a reasonable funding method is applied to the computation of—

(i) The normal cost of a plan for a plan year; and, if applicable,

(ii) The bases established under section 412(b)(2)(B), (C), and (D), and (3) (B) (“amortizable bases”).

(b) General rules for reasonable funding methods—(1) Basic funding formula. At any time, except as provided by the Commissioner, the present value of future benefits under a reasonable funding method must equal the sum of the following amounts:

(i) The present value of normal costs (taking into account future mandatory employee contributions, within the meaning of section 411(c)(2)(C), in the case of a contributory plan) over the future working lifetime of participants;

(ii) The sum of the unamortized portions of amortizable bases, if any, treating credit bases under section 412(b)(3)(B) as negative numbers; and

(iii) The plan assets, decreased by a credit balance (and increased by a debit balance) in the funding standard account under section 412(b).

(2) Normal cost. Normal cost under a reasonable funding method must be expressed as—

(i) A level dollar amount, or a level percentage of pay, that is computed from year to year on either an individual basis or an aggregate basis; or

(ii) An amount equal to the present value of benefits accruing under the method for a particular plan year.

(3) Application to shortfall. Paragraph (b)(2) will not fail to be satisfied merely because an amount described in (i) or (ii) is expressed as permitted under the shortfall method.

(c) Additional requirements—(1) Inclusion of all liabilities. Under a reasonable funding method, all liabilities of the plan for benefits, whether vested or not, must be taken into account.

(2) Production of experience gains and losses. If each actuarial assumption is exactly realized under a reasonable funding method, no experience gains or losses are produced.

(3) Plan population—(i) In general. Under a reasonable funding method, the plan population must include three classes of individuals: participants currently employed in the service of the employer; former participants who either terminated service with the employer, or retired, under the plan; and all other individuals currently entitled to benefits under the plan. See § 1.412(c)(3)-1(d)(2) for rules concerning anticipated future participants.

(ii) Limited exclusion for certain recent participants. Under a reasonable funding method, certain individuals may be excluded from the first class of individuals described in paragraph (c)(3)(i) of this section unless otherwise provided by the Commissioner. The excludable individuals are participants who would be excluded from participation by the minimum age or service requirement of section 410 but who, under the terms of the plan, participate immediately upon entering the service of the employer.

(iii) Special exclusion for “rule of parity” cases. Under a reasonable funding method, certain individuals may be excluded from the second class of individuals described in paragraph (c)(3)(i) of this section. The excludable individuals are those former participants who have terminated service with the employer without vested benefits and whose service might be taken into account in future years because the “rule of parity” of section 411(a)(6)(D) does not permit that service to be disregarded. However if the plan's experience as to separated employees' returning to service has been such that the exclusion described in this subparagraph would be unreasonable, the exclusion would no longer apply.

(4) Use of salary scale—(i) General acceptability. The use of a salary scale assumption is not inappropriate merely because of the funding method with which it is used. Therefore, in determining whether actuarial assumptions are reasonable, a salary scale will not be considered to be prohibited merely because a particular funding method is being used.

(ii) Projection to appropriate salary. Under a reasonable funding method, salary scales reflected in projected benefits must be the expected salary on which benefits would be based under the plan at the age when the receipt of benefits is expected to begin.

(5) Treatment of allocable items. Under a reasonable funding method that allocates assets to individual participants to determine costs, the allocation of assets among participants must be reasonable. An initial allocation of assets among participants will be considered reasonable only if it is in proportion to related liabilities. However, the Commissioner may determine, based on the facts and circumstances, that it is unreasonable to continue to allocate assets on this basis beyond the initial year. Under a reasonable funding method that allocates liabilities among different elements of past and future service, the allocation of liabilities must be reasonable.

(d) Prohibited considerations under a reasonable funding method—(1) Anticipated benefit changes—(i) In general. Except as otherwise provided by the Commissioner, a reasonable funding method does not anticipate changes in plan benefits that become effective, whether or not retroactively, in a future plan year or that become effective after the first day of, but during, a current plan year.

(ii) Exception for collectively bargained plans. A collectively bargained plan described in section 413(a) may on a consistent basis anticipate benefit increases scheduled to take effect during the term of the collective-bargaining agreement applicable to the plan. A plan's treatment of benefit increases scheduled in a collective bargaining agreement is part of its funding method. Accordingly, a change in a plan's treatment of such benefit increases (for example, ignoring anticipated increases after taking them into account) is a change of funding method.

(2) Anticipated future participants. A reasonable funding method must not anticipate the affiliation with the plan of future participants not employed in the service of the employer on the plan valuation date. However, a reasonable funding method may anticipate the affiliation with the plan of current employees who have not satisfied the participation requirements of the plan.

(e) Special rules for certain funding methods—(1) Applicability of special rules. Paragraph (e) of this section applies to a funding method that determines normal cost under paragraph (b)(2)(ii) of this section.

(2) Use of salary scale. For rules relating to use of a salary scale assumption, see paragraph (c)(4) of this section.

(3) Allocation of liabilities. In determining a plan's normal cost and accrued liability for a particular plan year, the projected benefits of the plan must be allocated between past years and future years. Except in the case of a career average pay plan, this allocation must be in proportion to the applicable rates of benefit accrual under the plan. Thus, the allocation to past years is effected by multiplying the projected benefit by a fraction. The numerator of the fraction is the participant's credited years of service. The denominator is the participant's total credited years of service at the anticipated benefit commencement date. Adjustments are made to account for changes in the rate of benefit accrual. An allocation based on compensation is not permitted. In the case of a career average pay plan, an allocation between past and future service benefits must be reasonable.

(f) Treatment of ancillary benefit costs—(1) General rule. Under a reasonable funding method, except as otherwise provided by this paragraph (f), ancillary benefit costs must be computed by using the same method used to compute retirement benefit costs under a plan.

(2) Ancillary benefit defined. For purposes of this paragraph an ancillary benefit is a benefit that is paid as a result of a specified event which—

(i) Occurs not later than a participant's separation from service, and

(ii) Was detrimental to the participant's health.

(3) Exception for certain insurance contracts. Under a reasonable funding method, regardless of the method used to compute retirement benefit costs, the cost of an ancillary benefit may equal the premium paid for that benefit under an insurance contract if—

(i) The ancillary benefit is provided under the contract, and

(ii) The benefit is guaranteed under the contract.

(4) Exception for 1-year term funding and other approved methods. [Reserved]

(5) Section 401(h) benefits. Section 412 does not apply to benefits that are described in section 401(h) and for which a separate account is maintained.

(g) Examples. The principles of this section are illustrated by the following examples:

Example 5.Assume that a plan, using method E, a unit credit funding method, calculates a participant's accrued benefit according to the following formula: 2 percent of final salary for the first 10 years of service and 1 percent of final salary for the years of service in excess of 10. Under the plan, no employee may be credited with more than 25 years of service. The actuarial assumptions for the valuation include a salary scale of 5 percent per year. For a participant at age 40 with 15 years of service, a current salary of $20,000 and a normal retirement age of 65, the accrued liability for the retirement benefit is the present value of an annuity of $16,932 per year, commencing at age 65. The $16,932 is calculated as follows: $$ (3.3864 is 1.05 raised to the 25th power; the 25th power reflects the difference between normal retirement age and attained age (65-40).) Salary under this method is projected to the age when the receipt of benefits is expected to begin. Therefore, method E meets the requirement of paragraph (c)(4) of this section. Also, the allocation of benefits under method E between past and future years of service meets the requirements of paragraph (e)(3) of this section.

(a) Introduction. This section prescribes effective dates for rules relating to reasonable funding methods, under section 412(c)(3) and § 1.412(c)(3)-1. Also, this section sets forth rules concerning adjustments to a plan's funding standard account that are necessitated by a change in funding method, and a provision setting forth procedural requirements for use of an optional phase-in of required changes.

(b) Effective date—(1) General rule. Except as otherwise provided by subparagraph (2) of this paragraph, § 1.412(c)(3)-1 applies to any valuation of a plan's liabilities (within the meaning of section 412(c)(9)) as of a date after April 30, 1981.

(2) Exception. If a collective bargaining agreement which determines contributions to a plan is in effect on April 30, 1981, then § 1.412(c)(3)-1 applies to any valuation of that plan's liabilities as of a date after the earlier of the date on which the last such collective bargaining agreement expires or April 30, 1984.

(3) Transitional rule. The reasonableness of a funding method used in making a valuation of a plan's liability as of a date before the effective date determined under subparagraph (1) or (2) of this paragraph is determined on the basis of such published guidance as was available on the date as of which the valuation was made.

(c) Change of funding method without approval—(1) In general. A plan that is required to change its funding method to comply with § 1.412(c)(3)-1 is not required to submit the change of funding method for approval as otherwise required by section 412(c)(5). However, this change must be described on Form 5500, Schedule B for the plan year with respect to which the change is first effective.

(2) Amortization base. An amortization base must be established in the plan year of the change in method equal to the change in the unfunded liability due to the change (where both unfunded liabilities are based on the same actuarial assumptions). Such a base must be amortized over 30 years in determining the charges or credits to the funding standard account, unless the Commissioner upon application permits amortization over a shorter period.

(d) Phase-in of additional funding required by new method—(1) In general. A plan that is required to change its funding method to comply with § 1.412(c)(3)-1 may elect to charge and credit the funding standard account as provided in this paragraph. An election under this paragraph shall be irrevocable.

(2) Credit in year of change. In the plan year of the change in method the funding standard account may be credited with an amount not in excess of 0.8 multiplied by the excess (if any) of—

(i) The normal cost under the new method plus the amortization charge (or minus the amortization credit) computed as described in § 1.412(c)(3)-2(c)(2), over

(ii) The normal cost under the prior method, for the plan year of the change in method.

(3) Credits in the next three years. In the three years following the year of the change the funding standard account may be credited with an amount not in excess of 0.6, 0.4, and 0.2 respectively in the first, second, and third years, multiplied by either of the following amounts, computed as of the last day of the year of credit—

(i) The excess described in § 1.412(c)(3)-2(d)(2) multiplied by a fraction (not greater than 1), the numerator of which is the number of participants in the year of the credit and the denominator of which is the number of participants in the year of the change, or, at the option of the plan,

(ii) The excess (if any) in the year of credit of—

(A) The net charge to the funding standard account based on the new method, over

(B) The net charge to the funding standing account based on the prior method.

(4) Computational rules. For purposes of the calculation described in § 1.412(c)(3)-2(d)(3)(ii), the net charge is the excess of charges under section 412(b)(2) (A) and (B) over the credits under section 412(b)(3)(B) (including the charge or credit described in § 1.412(c)(3)-2(c)) which would be required using the actuarial assumptions and plan benefit structure in effect on the last day of the plan year of change.

(5) Fifteen-year amortization of credits. The funding standard account shall be charged with 15-year amortization of each credit described in § 1.412(c)(3)-2(d) (2) and (3) beginning in the year following each such credit.

(6) Manner of election. An election under this paragraph shall be made by the claiming of the credits described in § 1.412(c)(3)-2(d) (2) and (3) on Schedule B to Form 5500 and by filing such other information as may be required by the Commissioner.

(e) Effect on shortfall method. The charges and credits described in this section apply in the shortfall method to the annual computation charge described in § 1.412(c)(1)-2(d). The amounts described in § 1.412(c)(3)-2(d) shall be determined before the application of the shortfall method.

(a) In general. Under section 412(h)(2) of the Internal Revenue Code of 1954, as added by section 1013(a) of the Employee Retirement Income Security Act of 1974 (88 Stat. 914) (hereinafter referred to as “the Act”), an insurance contract plan described in section 412(i) for a plan year is not subject to the minimum funding requirements of section 412 for that plan year. Consequently, if an individual or group insurance contract plan satisfies all of the requirements of paragraph (b)(2) or (c)(2) of this section, whichever are applicable, for the plan year, the plan is not subject to the requirements of section 412 for that plan year. The effective date for section 412 of the Code is determined under section 1017 of the Act. In general, in the case of a plan which was not in existence on January 1, 1974, this section applies for plan years beginning after September 2, 1974, and in the case of a plan in existence on January 1, 1974, to plan years beginning after December 31, 1975.

(b) Individual insurance contract plans. (1) An individual insurance contract plan is described in section 412(i) during a plan year if the plan satisfies the requirements of paragraph (b)(2) of this section for the plan year.

(2) The requirements of this paragraph are:

(i) The plan must be funded exclusively by the purchase from an insurance company or companies (licensed under the law of a State or the District of Columbia to do business with the plan) of individual annuity or individual insurance contracts, or a combination thereof. The purchase may be made either directly by the employer or through the use of a custodial account or trust. A plan shall not be considered to be funded otherwise than exclusively by the purchase of individual annuity or individual insurance contracts merely because the employer makes a payment necessary to comply with the provisions of section 411(c)(2) (relating to accrued benefit from employee contributions).

(ii) The individual annuity or individual insurance contracts issued under the plan must provide for level annual, or more frequent, premium payments to be paid under the plan for the period commencing with the date each individual participating in the plan became a participant and ending not later than the normal retirement age for that individual or, if earlier, the date the individual ceases his participation in the plan. Premium payments may be considered to be level even though items such as experience gains and dividends are applied against premiums. In the case of an increase in benefits, the contracts must provide for level annual payments with respect to such increase to be paid for the period commencing at the time the increase becomes effective. If payment commences on the first payment date under the contract occurring after the date an individual becomes a participant or after the effective date of an increase in benefits, the requirements of this subdivision will be satisfied even though payment does not commence on the date on which the individual's participation commenced or on the effective date of the benefit increase, whichever is applicable. If an individual accrues benefits after his normal retirement age, the requirements of this subdivision are satisfied if payment is made at the time such benefits accrue. If the provisions required by this subdivision are set forth in a separate agreement with the issuer of the individual contracts, they need not be included in the individual contracts.

(iii) The benefits provided by the plan for each individual participant must be equal to the benefits provided under his individual contracts at his normal retirement age under the plan provisions.

(iv) The benefits provided by the plan for each individual participant must be guaranteed by the life insurance company, described in paragraph (b)(2)(i) of this section, issuing the individual contracts to the extent premiums have been paid.

(v) Except as provided in the following sentence, all premiums payable for the plan year, and for all prior plan years, under the insurance or annuity contracts must have been paid before lapse. If the lapse has occurred during the plan year, the requirements of this subdivision will be considered to have been met if reinstatement of the insurance policy, under which the individual insurance contracts are issued, occurs during the year of the lapse and before distribution is made or benefits commence to any participant whose benefits are reduced because of the lapse.

(vi) No rights under the individual contracts may have been subject to a security interest at any time during the plan year. This subdivision shall not apply to contracts which have been distributed to participants if the security interest is created after the date of distribution.

(vii) No policy loans, including loans to individual participants, on any of the individual contracts may be outstanding at any time during the plan year. This subdivision shall not apply to contracts which have been distributed to participants if the loan is made after the date of distribution. An application of funds by the issuer to pay premiums due under the contracts shall be deemed not to be a policy loan if the amount of the funds so applied, and interest thereon, is repaid during the plan year in which the funds are applied and before distribution is made or benefits commence to any participant whose benefits are reduced because of such application.

(c) Group insurance contract plans. (1) A group insurance contract plan is described in section 412(i) during a plan year if the plan satisfies the requirements of subparagraph (2) for the plan year.

(2) The requirements of this subparagraph are:

(i) The plan must be funded exclusively by the purchase from an insurance company or companies, described in paragraph (b)(2)(i) of this section, of group annuity or group insurance contracts, or a combination thereof. The purchase may be made either directly by the employer or through the use of a custodial account or trust. A plan shall not be considered to be funded otherwise than exclusively by the purchase of group annuity or group insurance contracts merely because the employer makes a payment necessary to comply with the provisions of section 411 (c)(2) (relating to accrued benefit derived from employee contributions).

(ii) In the case of a plan funded by a group insurance contract or a group annuity contract the requirements of paragraph (b)(2)(ii) of this section must be satisfied by the group contract issued under the plan. Thus, for example, each individual participant's benefits under the group contract must be provided for by level annual, or more frequent, payments equivalent to the payments required to satisfy such paragraph. The requirements of this subdivision will not be satisfied if benefits for any individual are not provided for by level payments made on his behalf under the group contract.

(iii) The group annuity or group insurance contract must satisfy the requirements of clauses (iii), (iv), (v), (vi), and (vii) of paragraph (b)(2). Thus, for example, each participant's benefits provided by the plan must be equal to his benefits provided under the group contract at his normal retirement age.

(iv)(A) If the plan is funded by a group annuity contract, the value of the benefits guaranteed by the insurance company issuing the contract under the plan with respect to each participant under the contract must not be less than the value of such benefits which the cash surrender value would provide for that participant under any individual annuity contract plan satisfying the requirements of paragraph (b) and approved for sale in the State where the principal office of the plan is located.

(B) If the plan is funded by a group insurance contract, the value of the benefits guaranteed by the insurance company issuing the contract under the plan with respect to each participate under the contract must not be less than the value of such benefits which the cash surrender value would provide for that participant under any individual insurance contract plan satisfying the requirements of paragraph (b) and approved for sale in the State where the principal office of the plan is located.

(v) Under the group annuity or group insurance contract, premiums or other consideration received by the insurance company (and, if a custodial account or trust is used, the custodian or trustee thereof) must be allocated to purchase individual benefits for participants under the plan. A plan which maintains unallocated funds in an auxiliary trust fund or which provides that an insurance company will maintain unallocated funds in a separate account, such as a group deposit administration contract, does not satisfy the requirements of this subdivision.

(d) Combination of plans. A plan which is funded by a combination of individual contracts and a group contract shall be treated as a plan described in section 412 (i) for the plan year if the combination, in the aggregate, satisfies the requirements of this section for the plan year.

(a) Application of section 413(b) to certain collectively bargained plans—(1) In general. Section 413(b) sets forth special rules applicable to certain pension, profit-sharing, and stock bonus plans (and each trust which is a part of such a plan), hereinafter referred to as “section 413(b) plans”, described in paragraph (a)(2) of this section. Notwithstanding any other provision of the Code, a section 413(b) plan is subject to the special rules of section 413(b) (1) through (8) and paragraphs (b) through (i) of this section.

(2) Requirements. Section 413(b) applies to a plan (and each trust which is a part of such plan) if the plan is a single plan which is maintained pursuant to one or more agreements which the Secretary of Labor finds to be a collective bargaining agreement between employee representatives and one or more employers. A plan which provides benefits for employees of more than one employer is considered a single plan subject to the requirements of section 413(b) and this section if the plan is considered a single plan for purposes of applying section 414(l) (see § 1.414(l)-1(b)(1)). For purposes of determining whether one or more plans (or agreements) are a single plan, under sections 413(a) and 414(l), it is irrelevant that there are in form two or more separate plans (or agreements). For example, a single plan will be considered to exist where agreements are entered into separately by a national labor organization (or one or more local units of such organization), on one hand, and individual employers, on the other hand, if the plan is considered a single plan for purposes of applying section 414(l).

(3) Additional rules and effective dates. (i) If a plan is a section 413(b) plan at a relevant time, the rules of section 413(b) and this section apply, and the rules of section 413(c) and § 1.413-2 do not apply to the plan.

(ii) The qualification of a section 413(b) plan, at any relevant time, under section 401(a), 403(a), or 405(a), as modified by sections 413(b) and this section, is determined with respect to all employers maintaining the plan. Consequently, the failure by one employer maintaining the plan (or by the plan itself) to satisfy an applicable qualification requirement will result in the disqualification of the plan for all employers maintaining the plan.

(iii) Except as otherwise provided, section 413 (a) and (b) and this section apply to a plan for plan years beginning after December 31, 1953.

(b) Participation. Section 410 and the regulations thereunder shall be applied as if all employees of each of the employers who are parties to the collective-bargaining agreement and all such employees who are subject to the same benefit computation formula under the plan were employed by a single employer.

(c) Discrimination, etc.—(1) General rule. Section 401(a)(4) (relating to prohibited discrimination) and section 411(d)(3) (relating to vesting required on termination, partial termination, or discontinuance of contributions) shall be applied as if all the participants in the plan, who are subject to the same benefit computation formula and who are employed by employers who are parties to the collective bargaining agreement, are employed by a single employer.

(2) Application of discrimination rules. Under section 401(a)(4) and the regulations thereunder a plan is not qualified unless the contributions or benefits provided under the plan do not discriminate in favor of officers, shareholders or highly compensated employees (hereinafter referred to collectively as “the prohibited group”). The presence or absence of such discrimination under a plan to which this section applies at any time shall not be determined on an employer-by-employer basis, but rather by testing separately each group of employees who are subject to the same benefit computation formula to determine if there is discrimination within such group. Consequently, discrimination in contributions or benefits among two or more different groups or among employees in different groups covered by the plan may be present without causing the plan to be disqualified. However, the presence of prohibited discrimination within one such group will result in the disqualification of the plan for all groups. Section 401(a)(4) and the regulations thereunder provide rules relating to the determination of which employees are members of the prohibited group and to the determination of discrimination in contributions or benefits which are applicable to a plan to which this section applies. The determination of whether or not an individual employee is a highly compensated employee shall be based on the relationship of the compensation of the employee to the compensation of all the other employees of all employers who are maintaining the plan and have employees covered under the same benefit computation formula, whether or not such other employees are covered by the plan or are covered under the same benefit computation formula, rather than to the compensation of all the other employees of the employer of such individual employee.

(3) Application of termination, etc. rules. Section 411(d)(3) and the regulations thereunder (relating to vesting required in the case of a termination, partial termination, or complete discontinuance of contributions) apply to a plan subject to the provisions of this section. The requirements of section 411(d)(3) shall be applied as if all participants in the plan who are subject to the same benefit computation formula and who are employed by employers who are parties to the collective bargaining agreement are employed by a single employer. The determination of whether or not there is a termination, partial termination, or complete discontinuance of contributions shall be made separately for each such group of participants who are treated as employed by a single employer. Consequently, if there are two or more groups of participants, a termination, partial termination, or complete discontinuance can take place under a plan with respect to one group of participants but not with respect to another such group of participants or for the entire plan. See § 1.411(d)-2 for rules prescribed under section 411(d)(3).

(4) Effective dates and transitional rules. (i) Section 413(b)(2) and this paragraph apply to a plan for plan years beginning after December 31, 1953.

(ii) In applying the rules of this paragraph to a plan for plan years to which section 411 does not apply, section 401(a)(7) (as in effect on September 1, 1974) shall be substituted for section 411(d)(3). See § 1.401-6 for rules prescribed under section 401(a)(7) as in effect on September 1, 1974. See § 1.411(a)-2 for the effective dates of section 411.

(5) Examples. The provisions of this paragraph are illustrated by the following examples:

(d) Exclusive benefit. Under section 401(a), a plan is not qualified unless the plan is for the exclusive benefit of the employees (and their beneficiaries) of the employer establishing and maintaining the plan. Other qualification requirements under section 401(a) require the application of the exclusive benefit rule (for example, section 401(a)(2), which precludes diversion of plan assets). For purposes of applying the requirements of section 401(a) in determining whether a plan subject to this section is, with respect to each employer establishing and maintaining the plan, for the exclusive benefit of its employees (and their beneficiaries), all of the employees participating in the plan shall be treated as employees of each such employer. Thus, for example, contributions by employer A to a plan subject to this section could be allocated to employees of other employers maintaining the plan without violating the requirements of section 401(a)(2), because all the employees participating in the plan are deemed to be employees of A.

(e) Vesting. Section 411 (other than section 411(d)(3) relating to termination or partial termination; discontinuance of contributions) and the regulations thereunder shall be applied as if all employers who have been parties to the collective-bargaining agreement constituted a single employer. The application of any rules with respect to breaks in service under section 411 shall be made under regulations prescribed by the Secretary of Labor. Thus, for example, all the hours which an employee worked for each employer in a collectively-bargained plan would be aggregated in computing the employee's hours of service under the plan. See also 29 CFR Part 2530 (Department of Labor regulations relating to minimum standards for employee pension benefit plans.)

(f)-(h) [Reserved]

(i) Employees of labor unions—(1) General rule. For purposes of section 413(b) and this section, employees of employee representatives shall be treated as employees of an employer establishing and maintaining a plan to which section 413(b) and this section apply if, with respect to the employees of such representatives, the plan satisfies the nondiscrimination requirements of section 401(a)(4) (determined without regard to section 413(b)(2)) and the minimum participation and coverage requirements of section 410 (determined without regard to section 413(b)(1)). For purposes of the preceding sentence, the plan and any affiliated employee health or welfare plan shall be deemed to be an employee representative. If employees of employee representatives, the plan, or an affiliated employee health or welfare plan are covered by the plan and are not treated as employees of an employer establishing and maintaining the plan under the provisions of this paragraph, the plan fails to satisfy the qualification requirements of section 401(a). In addition, in order for such a plan to be qualified, the plan must satisfy the requirements of section 413(b) (1) and (2), relating to participation and discrimination, respectively; see paragraphs (b) and (c) of this section. For purposes of this paragraph, an affiliated health or welfare plan is a health or welfare plan that is maintained under the same collective bargaining agreement or agreements, and that covers the same membership.

(2) Effective dates and transitional rules. (i) Section 413(b)(8) and this paragraph apply to a plan for plan years beginning after December 31, 1953.

(ii) In applying the rules of this paragraph to a plan for plan years to which section 410 does not apply, section 401(a)(3) (as in effect on September 1, 1974) shall be substituted for section 410. See § 1.401-3 for rules prescribed under section 401(a)(3) as in effect on September 1, 1974. See § 1.410(a)-2 for the effective dates of section 410.

(3) Examples. The provisions of this paragraph are illustrated by the following examples:

(a) Application of section 413(c)—(1) In general. Section 413(c) describes certain plans (and each trust which is a part of any such plan) hereinafter referred to as “section 413(c) plans.” A plan (and each trust which is a part of such plan) is deemed to be a section 413(c) plan if it is described in subparagraph (2) of this paragraph. Notwithstanding any other provision of the code (not specifically in conflict with the special rules hereinafter mentioned), a section 413(c) plan is subject to the special rules of section 413(c) (1) through (6) and paragraphs (b) through (g) of this section.

(2) Section 413(c) plan. A plan (and each trust which is a part of such plan) is a section 413(c) plan if—

(i) The plan is a single plan, within the meaning of section 413(a) and § 1.413-1(a)(2), and

(ii) The plan is maintained by more than one employer.

(3) Additional rules. (i) If a plan is a collectively bargained plan described in § 1.413-1(a), the rules of section 413(c) and this section do not apply, and the rules of section 413(b) and § 1.413-1 do apply to the plan.

(ii) The special rules of section 413(b)(1) and § 1.413-1(b) relating to the application of section 410, other than the rules of section 410(a), do not apply to a section 413(c) plan. Thus, for example, the minimum coverage requirements of section 410(b) are generally applied to a section 413(c) plan on an employer-by-employer basis, taking into account the generally applicable rules such as section 401(a)(5) and section 414 (b) and (c).

(iii) The special rules of section 413(b)(2) and § 1.413-1(c) (relating to (A) section 401(a)(4) and prohibited discrimination, and (B) 411(d)(3) and vesting required on termination, partial termination, or discontinuance of contributions) do not apply to a section 413(c) plan. Thus, for example, the determination of whether or not there is a termination, within the meaning of section 411(d)(3), of a section 413(c) plan is made solely by reference to the rules of sections 411(d)(3) and 413(c)(3).

(iv) The qualification of a section 413(c) plan, at any relevant time, under section 401(a), 403(a) or 405(a), as modified by section 413(c) and this section, is determined with respect to all employers maintaining the section 413(c) plan. Consequently, the failure by one employer maintaining the plan (or by the plan itself) to satisfy an applicable qualification requirement will result in the disqualification of the section 413(c) plan for all employers maintaining the plan.

(4) Effective dates. Except as otherwise provided, section 413(c) and this section apply to a plan for plan years beginning after December 31, 1953.

(b) Participation. Section 410(a) and the regulations thereunder shall be applied as if all employees of each of the employers who maintain the plan were employed by a single employer.

(c) Exclusive benefit. In the case of a plan subject to this section, the exclusive benefit requirements of section 401(a) shall be applied to the plan in the same manner as under section 413(b)(3) and § 1.413-1(d).

(d) Vesting. Section 411 and the regulations thereunder shall be applied as if all employers who maintain the plan constituted a single employer. The application of any rules with respect to breaks in service under section 411 shall be made under regulations prescribed by the Secretary of Labor. Thus, for example, all the hours which an employee worked for each employer maintaining the plan would be aggregated in computing the employee's hours of service under the plan. See also 29 CFR Part 2530 (Department of Labor regulations relating to minimum standards for employee pension benefit plans).

(a) Defintion of controlled group of corporations. For purposes of this section, the term “controlled group of corporations” has the same meaning as is assigned to the term in section 1563(a) and the regulations thereunder, except that (1) the term “controlled group of corporations” shall not include an “insurance group” described in section 1563(a)(4), and (2) section 1563(e)(3)(C) (relating to stock owned by certain employees' trusts) shall not apply. For purposes of this section, the term “members of a controlled group” means two or more corporations connected through stock ownership described in section 1563(a) (1), (2), or (3), whether or not such corporations are “component members of a controlled group” within the meaning of section 1563(b). Two or more corporations are members of a controlled group at any time such corporations meet the requirements of section 1563(a) (as modified by this paragraph). For purposes of this section, if a corporation is a member of more than one controlled group of corporations, such corporation shall be treated as a member of each controlled group.

(b) Single plan adopted by two or more members. If two or more members of a controlled group of corporations adopt a single plan for a plan year, then the minimum funding standard provided in section 412, the tax imposed by section 4971, and the applicable limitations provided by section 404(a) shall be determined as if such members were a single employer. In such a case, the amount of such items and the allocable portion attributable to each member shall be determined in the manner provided in regulations under sections 412, 4971, and 404(a).

(c) Cross reference. For rules relating to the application of sections 401, 408(k), 410, 411, 415, and 416 with respect to two or more trades or businesses which are under common control, see section 414(c) and the regulations thereunder.

For purposes of applying the provisions of sections 401 (relating to qualified pension, profit-sharing, and stock bonus plans), 408(k) (relating to simplified employee pensions), 410 (relating to minimum participation standards), 411 (relating to minimum vesting standards), 415 (relating to limitations on benefits and contributions under qualified plans), and 416 (relating to top-heavy plans), all employees of two or more trades or businesses under common control within the meaning of § 1.414(c)-2 for any period shall be treated as employed by a single employer. See sections 401, 408(k), 410, 411, 415, and 416 and the regulations thereunder for rules relating to employees of trades or businesses which are under common control. See § 1.414(c)-5 for effective date.

(a) In general. For purposes of this section, the term “two or more trades or businesses under common control” means any group of trades or businesses which is either a “parent-subsidiary group of trades or businesses under common control” as defined in paragraph (b) of this section, a “brother-sister group of trades or businesses under common control” as defined in paragraph (c) of this section, or a “combined group of trades or businesses under common control” as defined in paragraph (d) of this section. For purposes of this section and §§ 1.414(c)-3 and 1.414(c)-4, the term “organization” means a sole proprietorship, a partnership (as defined in section 7701(a)(2)), a trust, an estate, or a corporation.

(b) Parent-subsidiary group of trades or businesses under common control—(1) In general. The term “parent-subsidiary group of trades or businesses under common control” means one or more chains of organizations conducting trades or businesses connected through ownership of a controlling interest with a common parent organization if—

(i) A controlling interest in each of the organizations, except the common parent organization, is owned (directly and with the application of § 1.414(c)-4(b)(1), relating to options) by one or more of the other organizations; and

(ii) The common parent organization owns (directly and with the application of § 1.414(c)-4(b)(1), relating to options) a controlling interest in at least one of the other organizations, excluding, in computing such controlling interest, any direct ownership interest by such other organizations.

(2) Controlling interest defined—(i) Controlling interest. For purposes of paragraphs (b) and (c) of this section, the phrase “controlling interest” means:

(A) In the case of an organization which is a corporation, ownership of stock possessing at least 80 percent of total combined voting power of all classes of stock entitled to vote of such corporation or at least 80 percent of the total value of shares of all classes of stock of such corporation;

(B) In the case of an organization which is a trust or estate, ownership of an actuarial interest of at least 80 percent of such trust or estate;

(C) In the case of an organization which is a partnership, ownership of at least 80 percent of the profits interest or capital interest of such partnership; and

(D) In the case of an organization which is a sole proprietorship, ownership of such sole proprietorship.

(ii) Actuarial interest. For purposes of this section, the actuarial interest of each beneficiary of trust or estate shall be determined by assuming the maximum exercise of discretion by the fiduciary in favor of such beneficiary. The factors and methods prescribed in § 20.2031-7 or, for certain prior periods, § 20.2031-7A (Estate Tax Regulations) for use in ascertaining the value of an interest in property for estate tax purposes shall be used for purposes of this subdivision in determining a beneficiary's actuarial interest.

(c) Brother-sister group of trades or businesses under common control—(1) In general. The term “brother-sister group of trades or businesses under common control” means two or more organizations conducting trades or businesses if (i) the same five or fewer persons who are individuals, estates, or trusts own (directly and with the application of § 1.414(c)-4) a controlling interest in each organization, and (ii) taking into account the ownership of each such person only to the extent such ownership is identical with respect to each such organization, such persons are in effective control of each organization. The five or fewer persons whose ownership is considered for purposes of the controlling interest requirement for each organization must be the same persons whose ownership is considered for purposes of the effective control requirement.

(2) Effective control defined. For purposes of this paragraph, persons are in “effective control” of an organization if—

(i) In the case of an organization which is a corporation, such persons own stock possessing more than 50 percent of the total combined voting power of all classes of stock entitled to vote or more than 50 percent of the total value of shares of all classes of stock of such corporation;

(ii) In the case of an organization which is a trust or estate, such persons own an aggregate actuarial interest of more than 50 percent of such trust or estate;

(iii) In the case of an organization which is a partnership, such persons own an aggregate of more than 50 percent of the profits interest or capital interest of such partnership; and

(iv) In the case of an organization which is a sole proprietorship, one of such persons owns such sole proprietorship.

(d) Combined group of trades or businesses under common control. The term “combined group of trades or businesses under common control” means any group of three or more organizations, if (1) each such organization is a member of either a parent-subsidiary group of trades or businesses under common control or a brother-sister group of trades or businesses under common control, and (2) at least one such organization is the common parent organization of a parent-subsidiary group of trades or businesses under common control and is also a member of a brother-sister group of trades or businesses under common control.

(e) Examples. The definitions of parent-subsidiary group of trades or businesses under common control, brother-sister group of trades or businesses under common control, and combined group of trades or businesses under common control may be illustrated by the following examples.

(a) In general. For purposes of § 1.414(c)-2 (b)(2)(i) and (c)(2), the term “interest” and the term “stock” do not include an interest which is treated as not outstanding under paragraph (b) of this section in the case of a parent-subsidiary group of trades or businesses under common control or under paragraph (c) of this section in the case of a brother-sister group of trades or businesses under common control. In addition, the term “stock” does not include treasury stock or nonvoting stock which is limited and preferred as to dividends. For definitions of certain terms used in this section, see paragraph (d) of this section.

(b) Parent-subsidiary group of trades or businesses under common control—(1) In general. If an organization (hereinafter in this section referred to as “parent organization”) owns (within the meaning of paragraph (b)(2) of this section)—

(i) In the case of a corporation, 50 percent or more of the total combined voting power of all classes of stock entitled to vote or 50 percent or more of the total value of shares of all classes of stock of such corporation.

(ii) In the case of a trust or an estate, an actuarial interest (within the meaning of § 1.414(c)-2(b)(2)(ii)) of 50 percent or more of such trust or estate, and

(iii) In the case of a partnership, 50 percent or more of the profits or capital interest of such partnership, then for purposes of determining whether the parent organization or such other organization (hereinafter in this section referred to as “subsidiary organization”) is a member of a parent-subsidiary group of trades or businesses under common control, an interest in such subsidiary organization excluded under paragraph (b) (3), (4), (5), or (6) of this section shall be treated as not outstanding.

(2) Ownership. For purposes of paragraph (b)(1) of this section, a parent organization shall be considered to own an interest in or stock of another organization which it owns directly or indirectly with the application of § 1.414(c)-4(b)(1) and—

(i) In the case of a parent organization which is a partnership, a trust, or an estate, with the application of paragraphs (b) (2), (3), and (4) of § 1.414(c)-4, and

(ii) In the case of a parent organization which is a corporation, with the application of § 1.414(c)-4(b)(4).

(3) Plan of deferred compensation. An interest which is an interest in or stock of the subsidiary organization held by a trust which is part of a plan of deferred compensation (within the meaning of section 406(a)(3) and the regulations thereunder) for the benefit of the employees of the parent organization or the subsidiary organization shall be excluded.

(4) Principal owners, officers, etc. An interest which is an interest in or stock of the subsidiary organization owned (directly and with the application of § 1.414(c)-4) by an individual who is a principal owner, officer, partner, or fiduciary of the parent organization shall be excluded.

(5) Employees. An interest which is an interest in or stock of the subsidiary organization owned (directly and with the application of § 1.414(c)-4) by an employee of the subsidiary organization shall be excluded if such interest or such stock is subject to conditions which substantially restrict or limit the employee's right (or if the employee constructively owns such interest or such stock, the direct or record owner's right) to dispose of such interest or such stock and which run in favor of the parent or subsidiary organization.

(6) Controlled exempt organization. An interest which is an interest in or stock of the subsidiary organization shall be excluded if owned (directly and with the application of § 1.414(c)-4) by an organization (other than the parent organization):

(i) To which section 501 (relating to certain educational and charitable organizations which are exempt from tax) applies, and

(ii) Which is controlled directly or indirectly (within the meaning of paragraph (d)(7) of this section) by the parent organization or subsidiary organization, by an individual, estate, or trust that is a principal owner of the parent organization, by an officer, partner, or fiduciary of the parent organization, or by any combination thereof.

(c) Brother-sister group of trades or businesses under common control—(1) In general. If five or fewer persons (hereinafter in this section referred to as “common owners”) who are individuals, estates, or trusts own (directly and with the application of § 1.414(c)-4)—

(i) In the case of a corporation, 50 percent or more of the total combined voting power of all classes of stock entitled to vote or 50 percent or more of the total value of shares of all classes of stock or such corporation,

(ii) In the case of a trust or an estate, an actuarial interest (within the meaning of § 1.414(c)-2(b)(2)(ii)) of 50 percent or more of such trust or estate, and

(iii) In the case of a partnership, 50 percent or more of the profits or capital interest of such partnership, then for purposes of determining whether such organization is a member of a brother-sister group of trades or businesses under common control, an interest in such organization excluded under paragraph (c) (2), (3), or (4) of this section shall be treated as not outstanding.

(2) Exempt employees' trust. An interest which is an interest in or stock of such organization held by an employees' trust described in section 401(a) which is exempt from tax under section 501(a) shall be excluded if such trust is for the benefit of the employees of such organization.

(3) Employees. An interest which is an interest in or stock of such organization owned (directly and with the application of § 1.414(c)-4) by an employee of such organization shall be excluded if such interest or stock is subject to conditions which run in favor of a common owner of such organization or in favor of such organization and which substantially restrict or limit the employee's right (or if the employee constructively owns such interest or stock, the direct or record owner's right) to dispose of such interest or stock.

(4) Controlled exempt organization. An interest which is an interest in or stock of such organization shall be excluded if owned (directly and with the application of § 1.414(c)-4) by an organization:

(i) To which section 501(c)(3) (relating to certain educational and charitable organizations which are exempt from tax) applies, and

(ii) Which is controlled directly or indirectly (within the meaning of paragraph (d)(7) of this section) by such organization, by an individual, estate, or trust that is a principal owner of such organization, by an officer, partner, or fiduciary of such organization, or by any combination thereof.

(d) Definitions—(1) Employee. For purposes of this section, the term “employee” has the same meaning such term is given in section 3306(i) of the Code (relating to definitions for purposes of the Federal Unemployment Tax Act).

(2) Principal owner. For purposes of this section, the term “principal owner” means a person who owns (directly and with the application of § 1.414(c)-4)—

(i) In the case of a corporation, 5 percent or more of the total combined voting power of all classes of stock entitled to vote in such corporation or 5 percent of more of the total value of shares of all classes of stock of such corporation;

(ii) In the case of a trust or estate, an actuarial interest of 5 percent or more of such trust or estate; or

(iii) In the case of a partnership, 5 percent or more of the profits or capital interest of such partnership.

(3) Officer. For purposes of this section, the term “officer” includes the president, vice-presidents, general manager, treasurer, secretary, and comptroller of a corporation, and any other person who performs duties corresponding to those normally performed by persons occupying such positions.

(4) Partner. For purposes of this section, the term “partner” means any person defined in section 7701(a)(2) (relating to definitions of partner).

(5) Fiduciary. For purposes of this section and § 1.414(c)-4, the term “fiduciary” has the same meaning as such term is given in section 7701(a)(6) and the regulations thereunder.

(6) Substantial conditions. (i) In general. For purposes of this section, an interest in or stock of an organization is subject to conditions which substantially restrict or limit the right to dispose of such interest or stock and which run in favor of another person if the condition extends directly or indirectly to such person preferential rights with respect to the acquisition of the direct owner's (or the record owner's) interest or stock. For a condition to be in favor of another person it is not necessary that such person be extended a discriminatory concession with respect to price. A right of first refusal with respect to an interest or stock in favor of another person is a condition which substantially restricts or limits the direct or record owner's right of disposition which runs in favor of such person. Further, any legally enforceable condition which prohibits the direct or record owner from disposing of his or her interest or stock without the consent of another person will be considered to be a substantial limitation running in favor of such person.

(ii) Special rule. For purposes of paragraph (c)(3) of this section only, if a condition which restricts or limits an employee's right (or direct or record owner's right) to dispose of his or her interest or stock also applies to the interest or stock in such organization held by a common owner pursuant to a bonafide reciprocal purchase arrangement, such condition shall not be treated as a substantial limitation or restriction. An example of a reciprocal purchase arrangement is an agreement whereby a common owner and the employee are given a right of first refusal with respect to stock of the employer corporation owned by the other party. If, however, the agreement also provides that the common owner has the right to purchase the stock of the employer corporation owned by the employee in the event the corporation should discharge the employee for reasonable cause, the purchase arrangement would not be reciprocal within the meaning of this subdivision.

(7) Control. For purposes of paragraphs (b)(6) and (c)(4) of this section, the term “control” means control in fact. The determination of whether there exists control in fact will depend upon all of the facts and circumstances of each case, without regard to whether such control is legally enforceable and irrespective of the method by which such control is exercised or exercisable.

(e) Examples. The provisions of this section may be illustrated by the following examples:

(f) Exception—(1) In general. If an interest in an organization (including stock of a corporation) is owned by a person directly or with the application of the rules of paragraph (b) of § 1.414 (c)-4 and such ownership results in the membership of that organization in a group of two or more trades or businesses under common control for any period, then the interest will not be treated as an excluded interest under paragraph (b) or (c) of this section if the result of applying such provisions is that the organization is not a member of a group of two or more trades or businesses under common control for the period.

(2) Example. The provisions of this paragraph may be illustrated by the following example:

(a) In general. In determining the ownership of an interest in an organization for purposes of § 1.414(c)-2 and § 1.414(c)-3, the constructive ownership rules of paragraph (b) of this section shall apply, subject to the operating rules contained in paragraph (c). For purposes of this section the term “interest” means: in the case of a corporation, stock; in the case of a trust or estate, an actuarial interest; in the case of a partnership, an interest in the profits or capital; and in the case of a sole proprietorship, the proprietorship.

(b) Constructive ownership—(1) Options. If a person has an option to acquire any outstanding interest in an organization, such interest shall be considered as owned by such person. For this purpose, an option to acquire an option, and each one of a series of such options shall be considered as an option to acquire such interest.

(2) Attribution from partnerships—(i) General. An interest owned, directly or indirectly, by or for a partnership shall be considered as owned by any partner having an interest of 5 percent or more in either the profits or capital of the partnership in proportion to such partner's interest in the profits or capital, whichever such proportion is greater.

(ii) Example. The provisions of paragraph (b)(2)(i) of this section may be illustrated by the following example:

(3) Attribution from estates and trusts—(i) In general. An interest in an organization (hereinafter called an “organization interest”) owned, directly or indirectly, by or for an estate or trust shall be considered as owned by any beneficiary of such estate or trust who has an actuarial interest of 5 percent or more in such organization interest, to the extent of such actuarial interest. For purposes of this subparagraph, the actuarial interest of each beneficiary shall be determined by assuming the maximum exercise of discretion by the fiduciary in favor of such beneficiary and the maximum use of the organization interest to satisfy the beneficiary's rights. A beneficiary of an estate or trust who cannot under any circumstances receive any part of an organization interest held by the estate or trust, including the proceeds from the disposition thereof, or the income therefrom, does not have an actuarial interest in such organization interest. Thus, where stock owned by a decedent's estate has been specifically bequeathed to certain beneficiaries and the remainder of the estate has been specifically bequeathed to other beneficiaries, the stock is attributable only to the beneficiaries to whom it is specifically bequeathed. Similarly a remainderman of a trust who cannot under any circumstances receive any interest in the stock of a corporation which is a part of the corpus of the trust (including any accumulated income therefrom or the proceeds from a disposition thereof) does not have an actuarial interest in such stock. However, an income beneficiary of a trust does have an actuarial interest in stock if he has any right to the income from such stock even though under the terms of the trust instrument such stock can never be distributed to him. The factors and methods prescribed in § 20.2031-7 or, for certain prior periods, § 20.2031-7A (Estate Tax Regulations) for use in ascertaining the value of an interest in property for estate tax purposes shall be used for purposes of this subdivision in determining a beneficiary's actuarial interest in an organization interest owned directly or indirectly by or for an estate or trust.

(ii) Special rules for estates. (A) For purposes of this paragraph (b)(3) with respect to an estate, property of a decedent shall be considered as owned by his or her estate if such property is subject to administration by the executor or administrator for the purposes of paying claims against the estate and expenses of administration notwithstanding that, under local law, legal title to such property vests in the decedent's heirs, legatees or devisees immediately upon death.

(B) For purposes of this paragraph (b)(3) with respect to an estate, the term “beneficiary” includes any person entitled to receive property of a decedent pursuant to a will or pursuant to laws of descent and distribution.

(C) For purposes of this paragraph (b)(3) with respect to an estate, a person shall no longer be considered a beneficiary of an estate when all the property to which he or she is entitled has been received by him or her, when he or she no longer has a claim against the estate arising out of having been a beneficiary, and when there is only a remote possibility that it will be necessary for the estate to seek the return of property from him or her or to seek payment from him or her by contribution or otherwise to satisfy claims against the estate or expenses of administration.

(iii) Grantor trusts, etc. An interest owned, directly or indirectly, by or for any portion of a trust of which a person is considered the owner under subpart E, part I, subchapter J of the Code (relating to grantors and others treated as substantial owners) is considered as owned by such person.

(4) Attribution from corporations—(i) General. An interest owned, directly or indirectly, by or for a corporation shall be considered as owned by any person who owns (directly and, in the case of a parent-subsidiary group of trades or businesses under common control, with the application of paragraph (b)(1) of this section, or in the case of a brother-sister group of trades or business under common control, with the application of this section), 5 percent or more in value of the stock in that proportion which the value of the stock which such person so owns bears to the total value of all the stock in such corporation.

(ii) Example. The provisions of paragraph (b)(4)(i) of this section may be illustrated by the following example:

(5) Spouse—(i) General rule. Except as provided in paragraph (b)(5)(ii) of this section, an individual shall be considered to own an interest owned, directly or indirectly, by or for his or her spouse, other than a spouse who is legally separated from the individual under a decree of divorce, whether interlocutory or final, or a decree of separate maintenance.

(ii) Exception. An individual shall not be considered to own an interest in an organization owned, directly or indirectly, by or for his or her spouse on any day of a taxable year of such organization, provided that each of the following conditions are satisfied with respect to such taxable year:

(A) Such individual does not, at any time during such taxable year, own directly any interest in such organization;

(B) Such individual is not a member of the board of directors, a fiduciary, or an employee of such organization and does not participate in the management of such organization at any time during such taxable year;

(C) Not more than 50 percent of such organization's gross income for such taxable year was derived from royalties, rents, dividends, interest, and annuities; and

(D) Such interest in such organization is not, at any time during such taxable year, subject to conditions which substantially restrict or limit the spouse's right to dispose of such interest and which run in favor of the individual or the individual's children who have not attained the age of 21 years. The principles of § 1.414(c)-3(d)(6)(i) shall apply in determining whether a condition is a condition described in the preceding sentence.

(iii) Definitions. For purposes of paragraph (b)(5)(ii)(C) of this section, the gross income of an organization shall be determined under section 61 and the regulations thereunder. The terms “interest”, “royalties”, “rents”, “dividends”, and “annuities” shall have the same meaning such terms are given for purposes of section 1244(c) and § 1.1244(c)-1(e)(1).

(6) Children, grandchildren, parents, and grandparents—(i) Children and parents. An individual shall be considered to own an interest owned, directly or indirectly, by or for the individual's children who have not attained the age of 21 years, and if the individual has not attained the age of 21 years, an interest owned, directly or indirectly, by or for the individual's parents.

(ii) Children, grandchildren, parents, and grandparents. If an individual is in effective control (within the meaning of § 1.414(c)-2(c)(2)), directly and with the application of the rules of this paragraph without regard to this subdivision, of an organization, then such individual shall be considered to own an interest in such organization owned, directly or indirectly, by or for the individual's parents, grandparents, grandchildren, and children who have attained the age of 21 years.

(iii) Adopted children. For purposes of this section, a legally adopted child of an individual shall be treated as a child of such individual.

(iv) Example. The provisions of this subparagraph (6) may be illustrated by the following example:

(c) Operating rules—(1) In general. Except as provided in paragraph (c)(2) of this section, an interest constructively owned by a person by reason of the application of paragraph (b) (1), (2), (3), (4), (5), or (6) of this section shall, for the purposes of applying such paragraph, be treated as actually owned by such person.

(2) Members of family. An interest constructively owned by an individual by reason of the application of paragraph (b) (5) or (6) of this section shall not be treated as owned by such individual for purposes of again applying such subparagraphs in order to make another the constructive owner of such interest.

(3) Precedence of option attribution. For purposes of this section, if an interest may be considered as owned under paragraph (b)(1) of this section (relating to option attribution) and under any other subparagraph of paragraph (b) of this section, such interest shall be considered as owned by such person under paragraph (b)(1) of this section.

(4) Examples. The provisions of this paragraph may be illustrated by the following examples:

(a) Application. This section applies to an organization that is exempt from tax under section 501(a). The rules of this section only apply for purposes of determining when entities are treated as the same employer for purposes of section 414(b), (c), (m), and (o) (including the sections referred to in section 414(b), (c), (m), (o), and (t)), and are in addition to the rules otherwise applicable under section 414(b), (c), (m), and (o) for determining when entities are treated as the same employer. Except to the extent set forth in paragraphs (d), (e), and (f) of this section, this section does not apply to any church, as defined in section 3121(w)(3)(A), or any qualified church-controlled organization, as defined in section 3121(w)(3)(B).

(b) General rule. In the case of an organization that is exempt from tax under section 501(a) (an exempt organization) whose employees participate in a plan, the employer with respect to that plan includes the exempt organization whose employees participate in the plan and any other organization that is under common control with that exempt organization. For this purpose, common control exists between an exempt organization and another organization if at least 80 percent of the directors or trustees of one organization are either representatives of, or directly or indirectly controlled by, the other organization. A trustee or director is treated as a representative of another exempt organization if he or she also is a trustee, director, agent, or employee of the other exempt organization. A trustee or director is controlled by another organization if the other organization has the general power to remove such trustee or director and designate a new trustee or director. Whether a person has the power to remove or designate a trustee or director is based on facts and circumstances. To illustrate the rules of this paragraph (b), if exempt organization A has the power to appoint at least 80 percent of the trustees of exempt organization B (which is the owner of the outstanding shares of corporation C, which is not an exempt organization) and to control at least 80 percent of the directors of exempt organization D, then, under this paragraph (b) and § 1.414(b)-1, entities A, B, C, and D are treated as the same employer with respect to any plan maintained by A, B, C, or D for purposes of the sections referenced in section 414(b), (c), (m), (o), and (t).

(c) Permissive aggregation with entities having a common exempt purpose—(1) General rule. For purposes of this section, exempt organizations that maintain a plan to which section 414(c) applies that covers one or more employees from each organization may treat themselves as under common control for purposes of section 414(c) (and, thus, as a single employer for all purposes for which section 414(c) applies) if each of the organizations regularly coordinates their day-to-day exempt activities. For example, an entity that provides a type of emergency relief within one geographic region and another exempt organization that provides that type of emergency relief within another geographic region may treat themselves as under common control if they have a single plan covering employees of both entities and regularly coordinate their day-to-day exempt activities. Similarly, a hospital that is an exempt organization and another exempt organization with which it coordinates the delivery of medical services or medical research may treat themselves as under common control if there is a single plan covering employees of the hospital and employees of the other exempt organization and the coordination is a regular part of their day-to-day exempt activities.

(2) Authority to permit aggregation. (i) For determining when entities are treated as the same employer under section 414(b), (c), (m), and (o), the Commissioner may issue rules of general applicability, in revenue rulings, notices, or other guidance published in the Internal Revenue Bulletin (see § 601.601(d)(2)(ii)(b) of this chapter), permitting other types of combinations of entities that include exempt organizations to elect to be treated as under common control for one or more specified purposes if:

(A) There are substantial business reasons for maintaining each entity in a separate trust, corporation, or other form; and

(B) Such treatment would be consistent with the anti-abuse standards in paragraph (f) of this section.

(ii) For example, this authority might be exercised in any situation in which the organizations are so integrated in their operations as to effectively constitute a single coordinated employer for purposes of section 414(b), (c), (m), and (o), including common employee benefit plans.

(d) Permissive disaggregation between qualified church controlled organizations and other entities. In the case of a church plan (as defined in section 414(e)) to which contributions are made by more than one common law entity, any employer may apply paragraphs (b) and (c) of this section to those entities that are not a church (as defined in section 403(b)(12)(B) and § 1.403(b)-2) separately from those entities that are churches. For example, in the case of a group of entities consisting of a church (as defined in section 3121(w)(3)(A)), a secondary school (that is treated as a church under § 1.403(b)-2), and several nursing homes each of which receives more than 25 percent of its support from fees paid by residents (so that none of them is a qualified church-controlled organization under § 1.403(b)-2 and section 3121(w)(3)(B)), the nursing homes may treat themselves as being under common control with each other, but not as being under common control with the church and the school, even though the nursing homes would be under common control with the school and the church under paragraph (b) of this section.

(e) Application to certain church entities under section 3121(w)(3). [Reserved]

(f) Anti-abuse rule. In any case in which the Commissioner determines that the structure of one or more exempt organizations (which may include an exempt organization and an entity that is not exempt from income tax) or the positions taken by those organizations has the effect of avoiding or evading any requirements imposed under section 401(a), 403(b), or 457(b), or any applicable section (as defined in section 414(t)), or any other provision for which section 414(c) applies, the Commissioner may treat an entity as under common control with the exempt organization.

(g) Examples. The provisions of this section are illustrated by the following examples:

(h) Applicable date. This section applies for plan years beginning after December 31, 2008.

(a) General rule. Except as provided in paragraph (b), (c), (e), or (f) of this section, the provisions of § 1.414(b)-1 and §§ 1.414(c)-1 through 1.414 (c)-4 shall apply for plan years beginning after September 2, 1974.

(b) Existing plans. In the case of a plan in existence on January 1, 1974, unless paragraph (c) of this section applies, the provisions of “§ 1.414 (b)-1 and §§ 1.414(c)-1 through 1.414(c)-4 shall apply for plan years beginning after December 31, 1975. For definition of the term “existing plan”, see § 1.410(a)-2(c).

(c) Existing plans electing new provisions. In the case of a plan in existence on January 1, 1974, for which the plan administrator makes an election under § 1.410 (a)-2(d), the provisions of § 1.414(b)-1 and §§ 1.414 (c)-1 through 1.414(c)-4 shall apply to the plan years elected under § 1.410 (a)-2 (d).

(d) Application. For purposes of the Employee Retirement Income Security Act of 1974, the provisions of § 1.414(b)-1 and §§ 1.414(c)-1 through 1.414(c)-4 do not apply for any period of time before the plan years described in paragraph (a), (b), or (c) of this section, whichever is applicable.

(e) Special rule. Notwithstanding paragraph (a), (b), or (c) of this section, § 1.414(c)-3 (f) is effective April 1, 1988.

(f) Transitional rule—(1) In general. The amendments made by T.D. 8179 apply to the plan years or period described in paragraphs (a), (b), or (c) of this section, whichever is applicable.

(2) Exception. In the case of a plan year or period beginning before March 2, 1988, if an organization—

(i) Is a member of a brother-sister group of trades or businesses under common control under § 11.414(c)-2(c), as in effect before removal by T.D. 8179 (“old group”), for such plan year or period, and

(ii) Is not such a member for such plan year or period because of the amendments made by such Treasury decision,

(a) General rule. For the purposes of part I of subchapter D of chapter 1 of the Code and the regulations thereunder, the term “church plan” means a plan established and at all times maintained for its employees by a church or by a convention or association of churches (hereinafter included within the term “church”) which is exempt from tax under section 501(a), provided that such plan meets the requirements of paragraphs (b) and (if applicable) (c) of this section. If at any time during its existence a plan is not a church plan because of a failure to meet the requirements set forth in this section, it cannot thereafter become a church plan.

(b) Unrelated businesses—(1) In general. A plan is not a church plan unless it is established and maintained primarily for the benefit of employees (or their beneficiaries) who are not employed in connection with one or more unrelated trades or businesses (within the meaning of section 513).

(2) Establishment or maintenance of a plan primarily for persons not employed in connection with one or more unrelated trades or businesses. (i) (A) A plan, other than a plan in existence on September 2, 1974, is established primarily for the benefit of employees (or their beneficiaries) who are not employed in connection with one or more unrelated trades or businesses if on the date the plan is established the number of employees employed in connection with the unrelated trades or businesses eligible to participate in the plan is less than 50 percent of the total number of employees of the church eligible to participate in the plan.

(B) A plan in existence on September 2, 1974, is to be considered established as a plan primarily for the benefit of employees (or their beneficiaries) who are not employed in connection with one or more unrelated trades or businesses if it meets the requirements of both paragraphs (b)(2)(ii) (A) and (B) (if applicable) in either of its first 2 plan years ending after September 2, 1974.

(ii) For plan years ending after September 2, 1974, a plan will be considered maintained primarily for the benefit of employees of a church who are not employed in connection with one or more unrelated trades or businesses if in 4 out of 5 of its most recently completed plan years—

(A) Less than 50 percent of the persons participating in the plan (at any time during the plan year) consist of and in the same year

(B) Less than 50 percent of the total compensation paid by the employer during the plan year (if benefits or contributions are a function of compensation) to employees participating in the plan is paid to,

(iii) Even though a plan does not meet the provisions of paragraph (b)(2)(ii) of this section, it nonetheless will be considered maintained primarily for the benefit of employees who are not employed in connection with one or more unrelated trades or businesses if the church maintaining the plan can demonstrate that based on all of the facts and circumstances such is the case. Among the facts and circumstances to be considered in evaluating each case are:

(A) The margin by which the plan fails to meet the provisions of paragraph (b)(2)(ii) of this section, and

(B) Whether the failure to meet such provisions was due to a reasonable mistake as to what constituted an unrelated trade or business or whether a particular person or group of persons were employed in connection with one or more unrelated trades or businesses.

(iv) For purposes of this section, an employee will be considered eligible to participate in a plan if such employee is a participant in the plan or could be a participant in the plan upon making mandatory employee contributions to the plan.

(3) Employment in connection with one or more unrelated trades or businesses. An employee is employed in connection with one or more unrelated trades or businesses of a church if a majority of such employee's duties and responsibilities in the employ of the church are directly or indirectly related to the carrying on of such trades or businesses. Although an employee's duties and responsibilities may be insignificant with respect to any one unrelated trade or business, such employee will nonetheless be considered as employed in connection with one or more unrelated trades or businesses if such employee's duties and responsibilities with respect to all of the unrelated trades or businesses of the church represent a majority of the total of such person's duties and responsibilities in the employ of the church.

(c) Plans of two or more employers. The term “church plan” does not include a plan which, during the plan year, is maintained by two or more employers unless—

(1) Each of the employers is a church that is exempt from tax under section 501(a), and

(2) With respect to the employees of each employer, the plan meets the provisions of paragraph (b)(2)(ii) of this section or would be determined to be a church plan based on all the facts and circumstances described in paragraph (b)(2)(iii) of this section.

(d) Special rule. (1) Notwithstanding paragraph (c)(1) of this section, a plan maintained by a church and one or more agencies of such church for the employees of such church and of such agency or agencies, that is in existence on January 1, 1974, shall be treated as a church plan for plan years ending after September 2, 1974, and beginning before January 1, 1983, provided that the plan is described in paragraph (c) of this section without regard to paragraph (c)(1) of this section, and the plan is not maintained by an agency which did not maintain the plan on January 1, 1974.

(2) For the purposes of section 414(e) and this section, an agency of a church means an organization which is exempt from tax under section 501 and which is either controlled by, or associated with, a church. For example, an organization, a majority of whose officers or directors are appointed by a church's governing board or by officials of a church, is controlled by a church within the meaning of this paragraph. An organization is associated with a church if it shares common religious bonds and convictions with that church.

(e) Religious orders and religious organizations. For the purpose of this section the term “church” includes a religious order or a religious organization if such order or organization (1) is an integral part of a church, and (2) is engaged in carrying out the functions of a church, whether as a civil law corporation or otherwise.

(f) Separately incorporated fiduciaries. A plan which otherwise meets the provisions of this section shall not lose its status as a church plan because of the fact that it is administered by a separately incorporated fiduciary such as a pension board or a bank.

(g) Cross reference. (1) For rules relating to treatment of church plans, see section 410(c), 411(e), 412(h), 4975(g), and the regulations thereunder.

(2) For rules relating to church plan elections, see section 410(d) and the regulations thereunder.

(a) General rule. For purposes of part I of subchapter D of chapter 1 of the Code and the regulations thereunder, a plan is a multiemployer plan for a plan year if all of the following requirements are satisfied:

(1) Number of contributing employers. More than one employer is required by the plan instrument or other agreement to contribute (or to have contributions made on its behalf) to the plan for the plan year.

(2) Collective bargaining agreement. The plan is maintained for the plan year pursuant to one or more collective bargaining agreements between employee representatives and more than one employer.

(3) Amount of contributions. Except as provided by paragraph (c) of this section (relating to the special rule for contributions exceeding 50 percent), the amount of contributions made under the plan for the plan year by or on behalf of each employer is less than 50 percent of the total amount of contributions made under the plan for such plan year by or on behalf of all employers.

(4) Benefits. The plan provides that the amount of benefits payable with respect to each employee participating in the plan is determined without regard to whether or not his employer continues as a member of the plan. If benefits accrued as a result of the participant's service with his employer during a period before such employer was a member of the plan, this requirement does not apply to the amount of those benefits, except that this requirement does apply to the amount of those benefits (i) which are accrued benefits derived from employee contributions, or (ii) which are accrued under a plan maintained by an employer prior to the time such employer became a member of the plan to which the requirements of this paragraph (a) are applied.

(5) Other requirements. The plan satisfies such other requirements as the Secretary of Labor by regulations prescribes under the authority of section 414(f)(1)(E) of the Code and section 3(37) of the Employee Retirement Income Security Act of 1974 (Pub. L. 93-406, 88 Stat. 839). See 29 CFR 2510.3-37.

(b) Special rules—(1) Amount of contributions. For purposes of paragraphs (a)(3) and (c) of this section, the amount of contributions made under the plan for the plan year by or on behalf of each employer shall be the sum of such contributions made on or before the last day of the plan year. For purposes of determining whether contributions are made on or before the last day of the plan year, the rule of section 412(c)(10) and the regulations thereunder (relating to the treatment of certain contributions made after the last day of the plan year as made on such last day) shall apply.

(2) Benefits. (i) For purposes of paragraph (a)(4) of this section, certain benefit amounts are treated as accrued as a result of the participant's service with an employer during a period before such employer was a member of the plan. The amount of such a benefit so treated is the difference (if any) between two calculated amounts. The first calculated amount is the participant's total accrued benefit calculated under the plan as of the date the employer ceased to be a member of the plan. The second calculated amount is the participant's accrued benefit calculated without regard to his service with such employer during the period before such employer was a member of the plan. However, under a special limitation, this difference may not exceed the benefit a participant accrued from service before his employer became a member of the plan. For purposes of this limitation, this benefit is the benefit accrued as of the date the employer ceases to be a member of the plan. An employer shall be deemed to be a member of the plan in a plan year if the employer is required by the plan instrument or other agreement to contribute (or to have contributions made on its behalf) to the plan for such plan year or if an employee of the employer accrues a benefit, on account of service with the employer during such plan year, under the plan for that plan year.

(ii) The provisions of paragraphs (a)(4) and (b)(2)(i) of this section are illustrated by the following example:

(iii) For purposes of paragraphs (a)(4) and (b)(2) of this section, if an employer for a period employs two or more individuals who, solely by reason of their employment, are participants in the plan and who do not belong to the same collective bargaining unit, the dates on which the employer became and ceased to be a member of the plan shall be determined separately on a class basis for individuals who belong to separate collective bargaining units, as separate classes, and for individuals who do not belong to a collective bargaining unit, as a further single separate class. Thus, such dates shall be determined with respect to individuals as a class who belong to the same collective bargaining unit (or who do not belong to a collective bargaining unit) without consideration of the employment by the employer of, or the participation in the plan by, other individuals (who do not belong to such collective bargaining unit and who may belong to another collective bargaining unit) or whether the employer is a member of the plan with respect to such other individuals. In no event, however, may service not attributable to service with a particular collective bargaining unit be disregarded under paragraphs (a)(4) and (b)(2) of this section merely because the employer ceases to maintain the plan with respect to such unit. Thus, for example, paragraphs (a)(4) and (b)(2) of this section do not permit the disregard of a period of service of an individual belonging to a collective bargaining unit prior to the time the employer became a member of the plan with respect to such unit to the extent that, during such period of service, the individual belonged to another collective bargaining unit with respect to which the employer was a member of the plan.

(3) Controlled groups. For purposes of section 414(f) and this section, all corporations which are members of a controlled group of corporations (within the meaning of section 1563(a) and the regulations thereunder, but determined without regard to section 1563(e)(3)(C) and the regulations thereunder) are deemed to be one employer.

(c) Contributions exceeding 50 percent. If a plan was a multiemployer plan as defined in this section for any plan year (including plan years ending prior to September 3, 1974), “75 percent” shall be substituted for “50 percent” in applying paragraph (a)(3) of this section for subsequent plan years until the first plan year following a plan year in which the amount contributed by or on behalf of one employer is 75 percent or more of the total amount of contributions made under the plan for that plan year by or on behalf of all of the employers making contributions. In such case “75 percent” shall not again be substituted for “50 percent” until the plan has met the requirements of paragraph (a) of this section (determined without regard to this paragraph) for one plan year.

(d) Examples. The application of this section is illustrated by the following examples. For purposes of these examples, assume that the plan meets the requirements of paragraphs (a) (1), (2), (4), and (5) of this section for each plan year.

(e) Retention of records. (1) For plan years ending prior to September 3, 1974, a plan may be required to furnish proof that it met the requirements of section 414(f) and this section for each plan year ending prior to that date to the extent necessary to show the applicability of the 75 percent test provided in paragraph (c) of this section.

(2) For plan years ending after September 2, 1974, a plan may be required to furnish proof that it met the requirements of section 414(f) and this section for 6 immediately preceding plan years.

(a) In general. For purposes of part I of subchapter D of chapter 1 of the Code and the regulations thereunder, if the instrument under which the plan is operated for a plan year specifically designates a person or a group of persons as plan administrator, the person or group of persons collectively is the plan administrator for the plan year. The instrument may specifically designate a plan administrator—

(1) By name,

(2) By reference to the person or group of persons holding a named position or positions,

(3) By reference to a procedure established under the terms of the instrument pursuant to which a plan administrator is designated, or

(4) By reference to the person or group of persons charged with specific responsibilities of plan administrator. Consistent with the provisions of section 405 (c) (1) of the Employee Retirement Income Security Act of 1974 (29 U.S.C. 1105 (c) (1)), a plan may provide for the allocation of specific responsibilities of plan administrator among named persons and for named persons to designate others to carry out such responsibilities. A person or group of persons may be designated as plan administrator in accordance with the rules of this paragraph even though the person or group of persons does not carry the specific title “plan administrator”. In the absence of a person or group of persons designated as the plan administrator (individually, collectively, or by designation of different specific administrative responsibilities), the plan administrator for the plan year is the person or group of persons specified in paragraph (b) of this section.

(b) Plan administrator not specifically designated. If no person or group of persons is specifically designated as the plan administrator for a plan year by the instrument under which the plan is operated, the plan administrator for such year is the person or group of persons determined under the following rules:

(1) Single employer. In the case of a plan maintained by a single employer, the employer is the plan administrator. If the employer is a corporation, the corporation is the plan administrator. However, the corporation's board of directors may authorize a person or group of persons to fulfill responsibilities of the corporation as plan administrator. In the absence of such authorization, any corporate officer authorized under law, corporate by-laws, or resolution of the board of directors to act on behalf of the corporation with respect to contracts of a value equivalent to the fair market value of the assets of the plan shall be presumed to have authority to fulfill responsibilities of the corporation as plan administrator. For purposes of this paragraph (b) (1), “employer” means the “employer” as defined in section 3 (5) of the Employee Retirement Income Security Act of 1974 (29 U.S.C. 1003 (5)).

(2) Employee organization. In the case of a plan maintained by an employee organization, the employee organization is the plan administrator.

(3) Group representing the parties. In the case of a plan maintained by two or more employers, or jointly by one or more employers and one or more employee organizations, the association, committee, joint board of trustees, or other similar group of representatives of the parties who maintain the plan, as the case may be, is the plan administrator. For purposes of this subparagraph (3), a plan shall be considered maintained by two or more employers or jointly by one or more employers and one or more employee organizations only if none of the parties has the express power, under the terms of the instrument under which the plan is operated, to terminate the plan unilaterally.

(4) Person in control of assets. In any case where a plan administrator may not be determined by application of paragraphs (a) and (b), (1), (2), and (3) of this section, the plan administrator is the person or persons actually responsible, whether or not under the terms of the plan, for the control, disposition, or management of the cash or property received by or contributed to the plan, irrespective of whether such control, disposition, or management is exercised directly by such person or persons or indirectly through an agent or trustee designated by such person or persons.

(a) In general—(1) Scope of the regulations. Sections 401(a)(12) and 414(l) apply only to plans to which section 411 applies without regard to section 411(e)(2). Thus, for example, these sections do not apply to a governmental plan within the meaning of section 414(d); a church plan, within the meaning of section 414(e), for which there has not been made the election under section 410(d) to have the participation, vesting, funding, etc. requirements apply; or a plan which at no time after September 2, 1974, provided for employer contributions.

(2) General rule. Under section 414(l),

(i) A trust which forms a part of a plan will not constitute a qualified trust under section 401, and

(ii) A plan will not be treated as being qualified under section 403 (a) and 405 (a), unless, in the case of a merger or consolidation (as defined in paragraph (b)(2) of this section), or a transfer of assets or liabilities (as defined in paragraph (b)(3) of this section), the following condition is satisfied. This condition requires that each participant receive benefits on a termination basis (as defined in paragraph (b)(5) of this section) from the plan immediately after the merger, consolidation or transfer which are equal to or greater than the benefits the participant would receive on a termination basis immediately before the merger, consolidation, or transfer.

(b) Definitions. For purposes of this section:

(1) Single plan. A plan is a “single plan” if and only if, on an ongoing basis, all of the plan assets are available to pay benefits to employees who are covered by the plan and their beneficiaries. For purposes of the preceding sentence, all the assets of a plan will not fail to be available to provide all the benefits of a plan merely because the plan is funded in part or in whole with allocated insurance instruments. A plan will not fail to be a single plan merely because of the following:

(i) The plan has several distinct benefit structures which apply either to the same or different participants,

(ii) The plan has several plan documents,

(iii) Several employers, whether or not affiliated, contribute to the plan,

(iv) The assets of the plan are invested in several trusts or annuity contracts, or

(v) Separate accounting is maintained for purposes of cost allocation but not for purposes of providing benefits under the plan.

(2) Merger or consolidation. The terms “merger” or “consolidation” means the combining of two or more plans into a single plan. A merger or consolidation will not occur merely because one or more corporations undergo a reorganization (whether or not taxable). Furthermore, a merger or consolidation will not occur if two plans are not combined into a single plan, such as by using one trust which limits the availability of assets of one plan to provide benefits to participants and beneficiaries of only that plan.

(3) Transfer of assets or liabilities. A “transfer of assets or liabilities” occurs when there is a diminution of assets or liabilities with respect to one plan and the acquisition of these assets or the assumption of these liabilities by another plan. For example, the shifting of assets or liabilities pursuant to a reciprocity agreement between two plans in which one plan assumes liabilities of another plan is a transfer of assets or liabilities. However, the shifting of assets between several funding media used for a single plan (such as between trusts, between annuity contracts, or between trusts and annuity contracts) is not a transfer of assets or liabilities.

(4) Spinoff. The term “spinoff” means the splitting of a single plan into two or more plans.

(5) Benefits on a termination basis. (i) The term “benefits on a termination basis” means the benefits that would be provided exclusively by the plan assets pursuant to section 4044 of the Employee Retirement Income Security Act of 1974 (“ERISA”) and the regulations thereunder if the plan terminated. Thus, the term does not include benefits that are guaranteed by the Pension Benefit Guaranty Corporation, but not provided by the plan assets.

(ii) For purposes of determining the benefits on a termination basis, the allocation of assets to various priority categories under section 4044 of ERISA must be made on the basis of reasonable actuarial assumptions. The assumptions used by the Pension Benefit Guaranty Corporation as of the date of the merger or spinoff are deemed reasonable for this purpose.

(iii) If a change in the benefit structure of a plan in conjunction with a merger, consolidation, or transfer of assets or liabilities alters the benefits on a termination basis, the change should be designated, at the time the merger, consolidation, or transfer occurs, to be effective either immediately before or immediately after that occurrence. In the event that no designation is made, the change in the benefit structure will be deemed to occur immediately after the merger, consolidation, or transfer of assets or liabilities.

(6) Lower funded plan. (i) The term “lower funded plan” generally means the plan which, immediately prior to the merger, would have its assets exhausted in a higher priority category than the other plan.

(ii) Where two plans, immediately prior to the merger, would have their assets exhausted in the same priority category of section 4044 of ERISA in the event of termination, the lower funded plan is the one in which the assets would satisfy a lesser proportion of the liability allocated to that priority category.

(7) Priority category. The term “priority category” means the category of benefits described in each paragraph of section 4044(a) of ERISA. References to higher or highest priority categories refer to those priority categories which receive the first allocation of asserts, i.e. the lowest paragraph numbers in section 4044(a).

(8) Separate accounting of assets. The term “separate accounting of assets” means the maintenance of an asset account with respect to a given group of participants which is:

(i) Credited with contributions made to the plan on behalf of the participants and with its allocable share of investment income, if any, and

(ii) Charged with benefits paid to the participants, and with its allocable share of investment losses or expenses.

(9) Present value of accrued benefit. For purposes of this section, the present value of an accrued benefit must be determined on the basis of reasonable actuarial assumptions. For this purpose, the assumptions used by the Pension Benefit Guaranty Corporation as of the date of the merger or spinoff are deemed reasonable.

(10) Valuation of plan assets. In determining the value of a plan's assets, the standards set forth in regulations prescribed by the Pension Benefit Guaranty Corporation (29 CFR Part 2611) shall be applied.

(11) Date of merger or spinoff. The actual date of a merger or spinoff shall be determined on the basis of the facts and circumstances of the particular situation. For purposes of this determination, the following factors, none of which is necessarily controlling, are relevant:

(i) The date on which the affected employees stop accruing benefits under one plan and begin coverage and benefit accruals under another plan.

(ii) The date as of which the amount of assets to be eventually transferred is calculated.

(iii) If the merger or spinoff agreement provides that interest is to accrue from a certain date to the date of actual transfer, the date from which such interest will accrue.

(c) Application of section 414(l)—(1) Two or more plans. (i) Section 414(l) does not apply unless more than a single plan is involved. It also does not apply unless at least a single plan assumes liabilities from another plan or obtains assets from another plan (as in a merger or spinoff). For purposes of section 414(l), a transfer of assets or liabilities will not be deemed to occur merely because a defined contribution plan is amended to become a defined benefit plan. This rule will apply even if, under the facts and circumstances of a particular case, a termination of the defined contribution plan will be considered to have occurred for purposes of other provisions of the Code.

(ii) The requirements of this subparagraph may be illustrated as follows:

(2) Multiemployer plans. Except to the extent provided by regulations of the Pension Benefit Guaranty Corporation, section 114(l) does not apply to any transaction to the extent that participants either before or after that transaction are covered under a multiemployer plan within the meaning of section 414(f). Until these regulations are issued, section 414(l) does not apply to any of the following situations:

(i) A multiemployer plan is split into two or more plans, one or more of which are not multiemployer plans, or (ii) A single employer plan is merged into a multiemployer plan.

(d) Merger of defined contribution plans. In the case of a merger of two or more defined contribution plans, the requirements of section 414(l) will be satisfied if all of the following conditions are met:

(1) The sum of the account balances in each plan equals the fair market value (determined as of the date of the merger) of the entire plan assets.

(2) The assets of each plan are combined to form the assets of the plan as merged.

(3) Immediately after the merger, each participant in the plan as merged has an account balance equal to the sum of the account balances the participant had in the plans immediately prior to merger.

(e) Merger of defined benefit plans—(1) General rule. Section 414(l) compares the benefits on a termination basis before and after the merger. If the sum of the assets of all plans is not less than the sum of the present values of the accrued benefit (whether or not vested) of all plans, the requirements of section 414(l) will be satisfied merely by combining the assets and preserving each participant's accrued benefits. This is so because all the accrued benefits of the plan as merged are provided on a termination basis by the plan as merged. However, if the sum of the assets of all plans is less than the sum of the present values of the accrued benefits (whether or not vested) in all plans, the accrued benefits in the plan as merged are not provided on a termination basis.

(2) Special schedule of benefits. Generally, for some participants, the benefits provided on a termination basis for the plan as merged would be different from the benefits provided on a termination basis in the plans prior to merger if the assets were merely combined and if each participant retained his accrued benefit. Some participants would, therefore, receive greater benefits on a termination basis as a result of the merger and some other participants would receive smaller benefits. Accordingly, the requirements of section 414(l) would not be satisfied unless the distribution on termination were modified in some manner to prevent any participant from receiving smaller benefits on a termination basis as a result of the merger. This is accomplished through modifying the application of section 4044 of ERISA by inserting a special schedule of benefits.

(f) Operational rules for the special schedule. The application of section 4044 of ERISA as modified by the schedule of benefits is accomplished by the following steps:

(1) Section 4044 is applied in the plan as merged through the priority categories fully satisfied by the assets of the lower funded plan immediately prior to the merger.

(2) The assets in the plan as merged are then allocated to the next priority category as a percentage of the value of the benefits that would otherwise be allocated to that priority category. That percentage is the ratio of (i) the assets allocated to the first priority category not fully satisfied by the lower funded plan immediately prior to the merger to (ii) the assets that would have been allocated had that priority category been fully satisfied.

(3) A schedule of benefits is formed listing participants and scheduled accrued benefits. The scheduled accrued benefit is the excess of the benefits provided on a termination basis with respect to any participant from the plans immediately prior to the merger, over the benefits provided on a termination basis in subparagraphs (1) and (2) of this paragraph immediately after the merger. After allocating the assets in accordance with subparagraph (2) of this paragraph, the assets are allocated to the schedule of benefits as follows:

(i) First the assets are allocated to the scheduled benefits to the extent that the participant would have benefits provided in subparagraph (4) of this paragraph if there were no scheduled benefits.

(ii) Then the assets are allocated to the scheduled benefits to the extent that the participant would have benefits provided pursuant to subparagraph (5) of this paragraph if there were no scheduled benefits.

(4) The assets are then allocated to those benefits in the priority category described in subparagraph (2) of this paragraph with respect to which assets were not allocated. This allocation is made to the extent that these benefits are not associated with benefits in the schedule.

(5) Finally, the assets are allocated in accordance with section 4044 with respect to priority categories lower than the priority category described in subparagraph (4) of this paragraph. This allocation is made to the extent that these benefits are not associated with benefits in the schedule.

(g) Successive mergers—(1) In general. In the case of a current merger of a defined benefit plan with another defined benefit plan which as a result of a previous merger has a special schedule, the rules of paragraphs (e) and (f) of this section apply as if the schedule were considered a category described in section 4044 of ERISA. Thus, a second schedule may be formed as a result of the current merger. The second schedule will be inserted in the priority category of section 4044 described in paragraph (f)(2) of this section as of the date of the current merger. This priority category may be higher, lower, or within the schedule of benefits existing on account of a previous merger. If this priority schedule is inserted within a schedule of benefits, a new single schedule of benefits replacing the old schedule of benefits would in effect be created.

(2) Allocation of assets. Assets in the new schedule of benefits are allocated as follows:

(i) First to the benefits remaining in the old schedule to the extent that there are assets immediately prior to the second merger to satisfy the original benefits,

(ii) Then to the benefits provided on a termination basis from the plans immediately prior to the second merger to the extent that they are not provided before the schedule after the second merger or in subdivision (i) of this subparagraph,

(iii) Then to benefits remaining in the original schedule not included in subdivision (i) of this subparagraph.

(h) De minimis rule for merger of defined benefit plan—(1) In general. In the case of a merger of a defined benefit plan (“smaller plan”) whose liabilities (i.e., the present value of accrued benefits, whether or not vested) are less than 3 percent of the assets of another defined benefit plan (“larger plan”) as of at least one day in the larger plan's plan year in which the merger of the two plans occurs, section 414(l) will be deemed to be satisfied if the following condition is met. The condition requires that a special schedule of benefits (consisting of all the benefits that would be provided by the smaller plan on a termination basis just prior to the merger) be payable in a priority category higher than the highest priority category in section 4044 of ERISA. Assets will be allocated to that schedule in accordance with the allocation of assets to scheduled benefits in paragraph (f)(3) of this section.

(2) Application to a series of mergers. In the case of a series of such mergers in a given plan year of the larger plan, the rule described in subparagraph (1) of this paragraph will apply only if the sum of the liabilities (whether or not vested) assumed by the larger plan are less than 3 percent of the assets of the larger plan as of at least one day in the plan year of the larger plan in which the mergers occurred.

(3) Application to a merger occurring over more than one plan year. In the case of a merger of a smaller plan or a portion thereof with a larger plan designed to occur in steps over more than one plan year of the larger plan, the entire transaction will be deemed to occur in the plan year of the larger plan which contains the first of these steps.

(4) Liabilities of the smaller plan. For purposes of subparagraphs (2) and (3) of this paragraph, mergers satisfying paragraphs (e), (f) or (g) of this section will be ignored in determining the sum of the liabilities assumed by the larger plan.

(i) Data maintenance—(1) Alternative to the special schedule. In the case of a merger which would require the creation of a special schedule in order to satisfy section 414(l), the schedule need not be created at the time of the merger if data sufficient to create the schedule is maintained. The schedule would only have to be created in the event of a subsequent plan termination or a subsequent spinoff. In that case the schedule must be determined as of the date of the merger.

(2) Required data. The data that must be maintained depends on the plan, and care should be taken to ensure that all necessary data is maintained. Furthermore, in order to take advantage of the data maintenance alternative provided in this paragraph, an enrolled actuary must certify to the plan administrator that each element of data necessary to determine the schedule as of the date of the merger is maintained. This certification must be based either upon the enrolled actuary's independent examination of the data, or upon his reliance, which under the circumstances of the particular situation must be reasonable, upon a written statement of the plan administrator concerning what data is actually being maintained.

(j) Five year rule—(1) Limitation on the required use of the special schedule. A plan will not fail to satisfy the requirements of section 414(l) merely because the effects of the special schedule created pursuant to paragraphs (e)(2) or (h) of this section are ignored 5 years after the date of a merger. Furthermore, the date maintained pursuant to paragraph (i) of this section need not be maintained for more than 5 years after the merger, if the plan does not have a spinoff or a termination within 5 years.

(2) Illustration. If Plans A and B merge to form Plan AB and if Plan AB merges with Plan C 3 years later to form Plan ABC and if Plan ABC terminates 4 years later, the data relating to the merger of Plans A and B need not be maintained for more than 5 years after the merger of Plans A and B. In addition, after 5 years have elapsed after the merger of Plans A and B, the effect of any special schedule created by the merger of Plans A and B on the schedule created by the merger of Plans AB and C may be ignored in determining the later schedule.

(k) Examples. The provisions of paragraphs (e) through (j) of this section may be illustrated by the following examples:

(l) Merger of defined benefit and defined contribution plan. In the case of a merger of a defined benefit plan with a defined contribution plan, one of the plans before the merger should be converted into the other type of plan (i.e., the defined benefit converted into a defined contribution or the defined contribution converted into a defined benefit) and either paragraph (d) or paragraphs (e) through (j) of this section, whichever is appropriate, should be applied.

(m) Spinoff of a defined contribution plan. In the case of a spinoff of a defined contribution plan, the requirements of section 414(l) will be satisfied if after the spinoff—

(1) The sum of the account balances for each of the participants in the resulting plans equals the account balance of the participant in the plan before the spinoff, and

(2) The assets in each of the plans immediately after the spinoff equals the sum of the account balances for all participants in that plan.

(n) Spinoff of a defined benefit plan—(1) General rule. In the case of a spinoff of a defined benefit plan, the requirements of section 414(l) will be satisfied if—

(i) All of the accrued benefits of each participant are allocated to only one of the spun off plans, and

(ii) The value of the assets allocated to each of the spun off plans is not less than the sum of the present value of the benefits on a termination basis in the plan before the spin off for all participants in that spun off plan.

(2) De minimis rule. In the case of a spin off the requirements of section 414(l) will be deemed to be satisfied if the value of the assets spun off—

(i) Equals the present value of the accrued benefits spun off (whether or not vested), and

(ii) In conjunction with other assets spun off during the plan year in which the spinoff occurs in accordance with this subparagraph, is less than 3 percent of the assets as of at least one day in that year.

(3) Special temporary rule. In the case of a defined benefit plan maintained for different groups of employees, which is a single plan (as defined in paragraph (b)(l) of this section) and under which there has been separate accounting of assets for each group, a spinoff of the plan on or before July 1, 1978, into a separate plan for each group will be deemed to satisfy section 414 (l) if—

(i) All the liabilities with respect to each group of employees are allocated to a separate plan for that group of employees, and

(ii) The assets that are separately accounted for with respect to each group of employees are allocated to the separate plan for that group of employees.

(o) Transfers of assets or liabilities. Any transfer of assets or liabilities will for purposes of section 414 (l) be considered as a combination of separate mergers and spinoffs using the rules of paragraphs (d), (e) through (j), (l), (m), or (n) of this section, whichever is appropriate. Thus, for example, if in accordance with the transfer of one or more employees, a block of assets and liabilities are transferred from Plan A to Plan B, each of which is a defined benefit plan, the transaction will be considered as a spinoff from Plan A and a merger of one of the spinoff plans with Plan B. The spinoff and merger described in the previous sentence would be subject to the requirements of paragraphs (n) and (e) through (j) of this section respectively.

Q&A-1—Q&A-8: [Reserved]. See § 1.414(q)-1T, Q&A-1 through Q&A-8 for further guidance.

Q-9: How is the top-paid group determined?

A-9: (a) [Reserved]. See § 1.414(q)-1T, Q&A-9(a) for further guidance.

(b) Number of employees in the top-paid group—(1) Exclusions. The number of employees who are in the top-paid group for a year is equal to 20 percent of the total number of active employees of the employer for such year. However, solely for purposes of determining the total number of active employees in the top-paid group for a year, the employees described in § 1.414(q)-1T, A-9(b)(1) (i), (ii) and (iii)(B) are disregarded. Paragraph (g) of this A-9 provides rules for determining those employees who are excluded for purposes of applying section 414(r)(2)(A), relating to the 50-employee requirement applicable to a qualified separate line of business.

(i)-(iii) [Reserved]. See § 1.414(q)-1T, Q&A-9(b)(1) (i) through (iii) for further guidance.

(2) Alternative exclusion provisions—(i)-(ii) [Reserved]. See § 1.414(q)-1T, Q&A-9(b)(2) (i) and (ii) for further guidance.

(iii) Method of election. The elections in this paragraph (b)(2) must be provided for in all plans of the employer and must be uniform and consistent with respect to all situations in which the section 414(q) definition is applicable to the employer. Thus, with respect to all plan years beginning in the same calendar year, the employer must apply the test uniformly for purposes of determining its top-paid group with respect to all its qualified plans and employee benefit plans. If either election is changed during the determination year, no recalculation of the look-back year based on the new election is required, provided the change in election does not result in discrimination in operation.

(c)-(f) [Reserved]. See § 1.414(q)-1T, Q&A-9 (c) through (f) for further guidance.

(g) Excluded employees under section 414(r)(2)(A)—(1) In general. This paragraph (g) provides the rules for determining which employees are excluded employees for purposes of applying section 414(r)(2)(A), relating to the 50-employee requirement applicable to a qualified separate line of business.

(2) Excluded employees—(i) Age and service exclusion. All employees are excluded who are described in § 1.414(q)-1T, A-9(b)(1)(i) (relating to exclusions based on age or service). For this purpose, the rules in § 1.414(q)-1T, A-9 (e) and (f) (relating respectively to the 17 1/2-hour rule and the 6-month rule) apply. However, the election in § 1.414(q)-1T, A-9(b)(2)(i) (permitting the employer to elect reduced minimum age or service requirements) does not apply.

(ii) Nonresident alien exclusion. All employees are excluded who are described in § 1.414(q)-1T, A-9(b)(1)(ii) (relating to the exclusion of nonresident aliens with no U.S.- source income from the employer).

(iii) Inclusion of employees covered under a collective bargaining agreement. All employees are included who are described in § 1.414(q)-1T, A-9(b)(1)(iii)(A) (relating to employees covered under a collective bargaining agreement) and who are not otherwise described in paragraph (g)(2) (i) or (ii) of this A-9. For this purpose, the exclusion in § 1.414(q)-1T, A-9(b)(1)(iii)(B) and the related election in § 1.414(q)-1T, A-9(b)(2)(ii) do not apply.

(3) Applicable period. The determination of which employees are excluded employees is made on the basis of the testing year specified in the regulations under section 414(r) and not on the basis of the determination year or the look-back year under section 414(q).

(h) Effective date. The provisions of this A-9 apply to plan years and testing years beginning on or after January 1, 1994.

Q&A-10 through Q&A-15: [Reserved]. See § 1.414(q)-1T, Q&A-10 through Q&A-15 for further guidance.

The following questions and answers relate to the definition of “highly compensated employee” provided in section 414(q). The definitions and rules provided in these questions and answers are provided solely for purposes of determining the group of highly compensated employees.

Q-1: To what employee benefit plans and statutory provisions is the definition of highly compensated employee contained in section 414(q) applicable?

A-1: (a) In general. This definition is applicable to statutory provisions that incorporate the definition by reference.

(b) Qualified retirement plans—(1) In general. Generally, this definition is incorporated in many of the nondiscrimination requirements applicable to pension, profit-sharing, and stock bonus plans qualified under section 401(a). See, e.g., the nondiscrimination provisions of sections 401(a) (4) and (5), 401(k)(3), 401(l), 401(m), 406(b), 407(b), 408(k), 410(b) and 411(d)(1). The definition is also incorporated by certain other provisions with respect to such plans, including the aggregation rules of section 414(m) and section 4975 (tax on prohibited transactions).

(2) Not applicable where not incorporated by reference. This definition is not applicable to qualified plan provisions that do not incorporate it. See, e.g., section 415 (limitations on contributions and benefits), with the exception of section 415(c)(3)(C) and 415(c)(6) (special rules for permanent and total disability and employee stock ownership plans respectively).

(c) Other employee benefit plans or arrangements. This definition is incorporated by various sections relating to employee benefit provisions. See, e.g., section 89 (certain other employee benefit plans), section 106 (accident and health plans), 117(d) (qualified tuition reduction), section 125 (cafeteria plans), section 129 (dependent care assistance programs), section 132 (certain fringe benefits), section 274 (certain entertainment, etc. expenses), section 423(b) (employee stock purchase plan provisions), section 501(c) (17) and (18) (certain exempt trusts providing benefits to employees), and section 505 (certain exempt organizations or trusts providing benefits to individuals). See the respective sections for the applicable effective dates.

(d) ERISA. This definition is not determinative with respect to any provisions of title I of the Employee Retirement Income Security Act of 1974 (ERISA), unless it is explicitly incorporated by reference (e.g., section 408(b)(1)(B)).

Q-2: Who is a highly compensated employee?

A-2: The group of employees (including former employees) who are highly compensated employees consists of both highly compensated active employees (see A-3 of this § 1.414(q)-1T) and highly compensated former employees (see A-4 of this § 1.414(q)-1T). In many circumstances, highly compensated active employees and highly compensated former employees are considered separately in applying the provisions for which the definition of highly compensated employees in section 414(q) is applicable. Specific rules with respect to the treatment of highly compensated active employees and highly compensated former employees will be provided in the regulations with respect to the sections to which the definition of highly compensated employees is applicable.

Q-3: Who is a highly compensated active employee?

A-3: (a) General rule. For purposes of the year for which the determination is being made (the determination year), a highly compensated active employee is any employee who, with respect to the employer, performs services during the determination year and is described in any one or more of the following groups applicable with respect to the look-back year calculation and/or determination year calculation for such determination year. See A-14 for rules relating to the periods for which the look-back year calculation and determination year calculation are to be made.

(1) Look-back year calculation.

(i) 5-percent owner. The employee is a 5-percent owner at any time during the look-back year (i.e., generally, the 12-month period immediately preceding the determination year; see A-14. (See A-8 of this § 1.414(q)-1T.)

(ii) Compensation above $75,000. The employee receives compensation in excess of $75,000 during the look-back year.

(iii) Compensation above $50,000 and top-paid group. The employee receives compensation in excess of $50,000 during the look-back year and is a member of the top-paid group for the look-back year. (See A-9 of this § 1.414(q)-1T.)

(iv) Officer. The employee is an “includible officer” during the look-back year. (See A-10 of this § 1.414(q)-1T.)

(2) Determination year calculation.

(i) 5-percent owner. The employee is a 5-percent owner at any time during the determination year. (See A-8 of this § 1.414(q)-1T.)

(ii) Top-100 employees. The employee is both (A) described in paragraph (a)(1)(i), (ii) and/or (iv) of this A-3, when such paragraphs are modified to substitute the determination year for the look-back year, and (B) one of the 100 employees who receive the most compensation from the employer during the determination year.

(b) Rounding and tie-breaking rules. In making the look-back year and determination year calculations for a determination year, it may be necessary for an employer to adopt a rule for rounding calculations (e.g., in determining the number of employees in the top-paid group). In addition, it may be necessary to adopt a rule breaking ties among two or more employees (e.g., in identifying those particular employees who are in the top-paid group or who are among the 100 most highly compensated employees). In such cases, the employer may adopt any rounding or tie-breaking rules it desires, so long as such rules are reasonable, nondiscriminatory, and uniformly and consistently applied.

(c) Adjustments to dollar thresholds—(1) Indexing of dollar thresholds. The dollar amounts in paragraph (a)(1) (i) and (ii) of this A-3 are indexed at the same time and in the same manner as the section 415(b)(1)(A) dollar limitation for defined benefit plans.

(2) Applicable dollar threshold. The applicable dollar amount for a particular determination year or look-back year is the dollar amount for the calendar year in which such determination year or look-back year begins. Thus, the dollar amount for purposes of determining the highly compensated active employees for a particular look-back year is based on the calendar year in which such look-back year begins, not the calendar year in which such look-back year ends or in which the determination year with respect to such look-back year begins.

(d) Employees described in more than one group. An individual who is a highly compensated active employee for a determination year, by reason of being described in one group in paragraph (a) of this A-3, under either the look-back year calculation or the determination year calculation, is not disregarded in determining whether another individual is a highly compensated active employee by reason of being described in another group under paragraph (a). For example, an individual who is a highly compensated active employee for a determination year, by reason of being a 5-percent owner during such year, who receives compensation in excess of $50,000 during both the look-back year and the determination year, is taken into account in determining the group of employees who are highly compensated active employees for such determination year by reason of receiving more than $50,000, and being in the top-paid group under either or both the look-back year calculation or determination year calculation for such determination year.

(e) Examples. The following examples, in which the determination year and look-back year are the calendar year, are illustrative of the rules in paragraph (a) of this A-3. For purposes of these examples, the threshold dollar amounts in paragraph (a)(1) (ii) and (iii) of this A-3 are not increased pursuant to paragraph (c) of this A-3.
