§ 411.
(a)
General rule
A trust shall not constitute a qualified trust under section 401(a) unless the plan of which such trust is a part provides that an employee’s right to his normal retirement benefit is nonforfeitable upon the attainment of normal retirement age (as defined in paragraph (8)) and in addition satisfies the requirements of paragraphs (1), (2), and (11) of this subsection and the requirements of subsection (b)(3), and also satisfies, in the case of a defined benefit plan, the requirements of subsection (b)(1) and, in the case of a defined contribution plan, the requirements of subsection (b)(2).
(1)
Employee contributions
(2)
Employer contributions
(A)
Defined benefit plans
(iii)
3 to 7 year vesting
(B)
Defined contribution plans
(iii)
2 to 6 year vesting
(3)
Certain permitted forfeitures, suspensions, etc.
For purposes of this subsection—
(A)
Forfeiture on account of death
(B)
Suspension of benefits upon reemployment of retiree
A right to an accrued benefit derived from employer contributions shall not be treated as forfeitable solely because the plan provides that the payment of benefits is suspended for such period as the employee is employed, subsequent to the commencement of payment of such benefits—
(i)
in the case of a plan other than a multi-employer plan, by the employer who maintains the plan under which such benefits were being paid; and
(ii)
in the case of a multiemployer plan, in the same industry, the same trade or craft, and the same geographic area covered by the plan as when such benefits commenced.
The Secretary of Labor shall prescribe such regulations as may be necessary to carry out the purposes of this subparagraph, including regulations with respect to the meaning of the term “employed”.
(C)
Effect of retroactive plan amendments
(D)
Withdrawal of mandatory contribution
(i)
A right to an accrued benefit derived from employer contributions shall not be treated as forfeitable solely because the plan provides that, in the case of a participant who does not have a nonforfeitable right to at least 50 percent of his accrued benefit derived from employer contributions, such accrued benefit may be forfeited on account of the withdrawal by the participant of any amount attributable to the benefit derived from mandatory contributions (as defined in subsection (c)(2)(C)) made by such participant.
(ii)
Clause (i) shall not apply to a plan unless the plan provides that any accrued benefit forfeited under a plan provision described in such clause shall be restored upon repayment by the participant of the full amount of the withdrawal described in such clause plus, in the case of a defined benefit plan, interest. Such interest shall be computed on such amount at the rate determined for purposes of subsection (c)(2)(C) on the date of such repayment (computed annually from the date of such withdrawal). The plan provision required under this clause may provide that such repayment must be made (I) in the case of a withdrawal on account of separation from service, before the earlier of 5 years after the first date on which the participant is subsequently re-employed by the employer, or the close of the first period of 5 consecutive 1-year breaks in service commencing after the withdrawal; or (II) in the case of any other withdrawal, 5 years after the date of the withdrawal.
(iii)
In the case of accrued benefits derived from employer contributions which accrued before September 2, 1974, a right to such accrued benefit derived from employer contributions shall not be treated as forfeitable solely because the plan provides that an amount of such accrued benefit may be forfeited on account of the withdrawal by the participant of an amount attributable to the benefit derived from mandatory contributions (as defined in subsection (c)(2)(C)) made by such participant before September 2, 1974
if such amount forfeited is proportional to such amount withdrawn. This clause shall not apply to any plan to which any mandatory contribution is made after
(iv)
For purposes of this subparagraph, in the case of any class-year plan, a withdrawal of employee contributions shall be treated as a withdrawal of such contributions on a plan year by plan year basis in succeeding order of time.
(v)
For nonforfeitability where the employee has a nonforfeitable right to at least 50 percent of his accrued benefit, see section 401(a)(19).
(E)
Cessation of contributions under a multiemployer plan
(F)
Reduction and suspension of benefits by a multiemployer plan
A participant’s right to an accrued benefit derived from employer contributions under a multiemployer plan shall not be treated as forfeitable solely because—
(i)
the plan is amended to reduce benefits under section 4281 of the Employee Retirement Income Security Act of 1974, or
(ii)
benefit payments under the plan may be suspended under section 418E or under section 4281 of the Employee Retirement Income Security Act of 1974.
(G)
Treatment of matching contributions forfeited by reason of excess deferral or contribution or permissible withdrawal
(4)
Service included in determination of nonforfeitable percentage

(A)
years of service before age 18;

years of service before January 1, 1971, unless the employee has had at least 3 years of service after December 31, 1970;
(F)
years of service before the first plan year to which this section applies, if such service would have been disregarded under the rules of the plan with regard to breaks in service as in effect on the applicable date; and
(G)
in the case of a multiemployer plan, years of service—
(i)
with an employer after—
(I)
a complete withdrawal of that employer from the plan (within the meaning of section 4203 of the Employee Retirement Income Security Act of 1974), or
(II)
to the extent permitted in regulations prescribed by the Secretary, a partial withdrawal described in section 4205(b)(2)(A)(i) of such Act in conjunction with the decertification of the collective bargaining representative, and
(ii)
with any employer under the plan after the termination date of the plan under section 4048 of such Act.

In general
For purposes of paragraph (4), in the case of a nonvested participant, years of service with the employer or employers maintaining the plan before any period of consecutive 1-year breaks in service shall not be required to be taken into account if the number of consecutive 1-year breaks in service within such period equals or exceeds the greater of—
(I)
5, or
(II)
the aggregate number of years of service before such period.
(ii)
Years of service not taken into account

(III)
by reason of the placement of a child with the individual in connection with the adoption of such child by such individual, or

Hours treated as hours of service
The hours described in this clause are—
(I)
the hours of service which otherwise would normally have been credited to such individual but for such absence, or
(II)
in any case in which the plan is unable to determine the hours described in subclause (I), 8 hours of service per day of absence,
except that the total number of hours treated as hours of service under this clause by reason of any such pregnancy or placement shall not exceed 501 hours.
(iii)
Year to which hours are credited
The hours described in clause (ii) shall be treated as hours of service as provided in this subparagraph—
(I)
only in the year in which the absence from work begins, if a participant would be prevented from incurring a 1-year break in service in such year solely because the period of absence is treated as hours of service as provided in clause (i); or
(II)
in any other case, in the immediately following year.
(v)
Information required to be filed
A plan shall not fail to satisfy the requirements of this subparagraph solely because it provides that no credit will be given pursuant to this subparagraph unless the individual furnishes to the plan administrator such timely information as the plan may reasonably require to establish—
(I)
that the absence from work is for reasons referred to in clause (i), and
(II)
the number of days for which there was such an absence.
(7)

In general
For purposes of this section, the term “accrued benefit” means—

(ii)
in the case of a plan which is not a defined benefit plan, the balance of the employee’s account.
(B)
Effect of certain distributions
Notwithstanding paragraph (4), for purposes of determining the employee’s accrued benefit under the plan, the plan may disregard service performed by the employee with respect to which he has received—
(i)
a distribution of the present value of his entire nonforfeitable benefit if such distribution was in an amount (not more than the dollar limit under section 411(a)(11)(A)) permitted under regulations prescribed by the Secretary, or
(ii)
a distribution of the present value of his nonforfeitable benefit attributable to such service which he elected to receive.
Clause (i) of this subparagraph shall apply only if such distribution was made on termination of the employee’s participation in the plan. Clause (ii) of this subparagraph shall apply only if such distribution was made on termination of the employee’s participation in the plan or under such other circumstances as may be provided under regulations prescribed by the Secretary.
(C)
Repayment of subparagraph (B) distributions
For purposes of determining the employee’s accrued benefit under a plan, the plan may not disregard service as provided in subparagraph (B) unless the plan provides an opportunity for the participant to repay the full amount of the distribution described in such subparagraph (B) with, in the case of a defined benefit plan, interest at the rate determined for purposes of subsection (c)(2)(C) and provides that upon such repayment the employee’s accrued benefit shall be recomputed by taking into account service so disregarded. This subparagraph shall apply only in the case of a participant who—
(i)
received such a distribution in any plan year to which this section applies, which distribution was less than the present value of his accrued benefit,
(ii)
resumes employment covered under the plan, and
(iii)
repays the full amount of such distribution with, in the case of a defined benefit plan, interest at the rate determined for purposes of subsection (c)(2)(C).
The plan provision required under this subparagraph may provide that such repayment must be made (I) in the case of a withdrawal on account of separation from service, before the earlier of 5 years after the first date on which the participant is subsequently re-employed by the employer, or the close of the first period of 5 consecutive 1-year breaks in service commencing after the withdrawal; or (II) in the case of any other withdrawal, 5 years after the date of the withdrawal.

(9)
Normal retirement benefit
For purposes of this section, the term “normal retirement benefit” means the greater of the early retirement benefit under the plan, or the benefit under the plan commencing at normal retirement age. The normal retirement benefit shall be determined without regard to—
(A)
medical benefits, and
(B)
disability benefits not in excess of the qualified disability benefit.
For purposes of this paragraph, a qualified disability benefit is a disability benefit provided by a plan which does not exceed the benefit which would be provided for the participant if he separated from the service at normal retirement age.

subject to subparagraph (B), the requirements of subsection (a)(2), or
(ii)
