The definitions below are used to define terms for purposes of this part:

Align or alignment means to cause to be sufficiently similar, or have sufficient similarity, as to produce a conditional prepayment rate (CPR) divergence of less than 2 percentage points in the three-month CPR for a cohort, and less than 5 percentage points in the three-month CPR for a the fastest paying quartile of a cohort (or less than the prevailing percentage thresholds for alignment set by FHFA, per § 1248.5(c)).

Cohort means all TBA-eligible securities with the same coupon, maturity, and loan-origination year where the combined unpaid principal balance of such securities issued by both Enterprises exceeds $10 billion.

Conditional Prepayment Rate or CPR, also known as the constant prepayment rate, means the rate at which investors receive outstanding principal in advance of scheduled principal payments. This includes receipts of principal that result from borrower prepayments and for any other reason. The CPR is expressed as a compound annual rate.

Covered Programs, Policies, or Practices means management decisions or actions that have reasonably foreseeable effects on cash flows to TBA-eligible MBS investors (e.g., effects that result from prepayment rates and the circumstances under which mortgage loans are removed from MBS). These generally include management decisions or actions about: Single-family guarantee fees; loan level price adjustments and delivery fee portions of single-family guarantee fees; the spread between the note rate on the mortgage and the pass-through coupon on the TBA-eligible MBS; eligibility standards for sellers and servicers; financial and operational standards for private mortgage insurers; requirements related to the servicing of distressed loans that collateralize TBA-eligible securities; streamlined modification and refinance programs; removal of mortgage loans from securities; servicer compensation; proposals that could materially change the credit risk profile of the single-family mortgages securitized by an Enterprise; selling guide requirements for documenting creditworthiness, ability to repay, and adherence to collateral standards; refinances of HARP-eligible loans; contract provisions under which certain sellers commit to sell to an Enterprise a minimum share of the mortgage loans they originate that are eligible for sale to the Enterprises; loan modification offerings; loss mitigation practices during disasters; alternatives to repurchase for representation and warranty violations; and other actions.

Fastest paying quartile of a cohort means the quartile of a cohort that has the fastest prepayment speeds as measured by the three-month CPR. The quartiles shall be determined by ranking outstanding TBA-eligible securities with the same coupon, maturity, and loan-origination year by the three-month CPR, excluding specified pools, and dividing each cohort into four parts such that the total unpaid principal balance of the pools included in each part is equal.

Material misalignment means divergence of at least 3 percentage points in the three-month CPR for a cohort or at least 8 percentage points in the three-month CPR for a fastest paying quartile of a cohort, or a prolonged misalignment (as determined by FHFA), or divergence greater than either of the corresponding prevailing percentage thresholds set by FHFA, per § 1248.5(c).

Misalign or misalignment means to diverge by, or a divergence of, 2 percentage points or more, in the three-month CPR for a cohort or 5 percentage points or more, in the three-month CPR for a fastest paying quartile of a cohort (or more than either of the corresponding prevailing percentage thresholds set by FHFA, per § 1248.5(c)).

Mortgage-backed security or MBS means securities collateralized by a pool or pools of single-family mortgages.

Specified pools means pools of mortgages backing TBA-eligible MBS that have a maximum loan size of $200,000, a minimum loan-to-value ratio at the time of loan origination of 80 percent, or a maximum FICO score of 700, or where all mortgages in the pool finance investor-owned properties or properties in the states of New York or Texas or the Commonwealth of Puerto Rico.

Supers means single-class re-securitizations of UMBS.

Three-month conditional prepayment rate (CPR3) means the annualized measure of prepayments for a three month interval calculated as follows:

To-Be-Announced Eligible Mortgage-Backed Security (TBA-Eligible MBS) means Enterprise MBS (including Freddie Mac Participation Certificates, Giants, MBS, UMBS, and Supers; and Fannie Mae MBS, Megas, UMBS, and Supers) that meet criteria such that the market considers them sufficiently fungible to be forward traded in the TBA market.

Uniform Mortgage Backed Security or UMBS means a single-class MBS backed by fixed-rate mortgage loans on one-to-four unit (single-family) properties issued by either Enterprise which has the same characteristics (such as payment delay, pooling prefixes, and minimum pool submission amounts) regardless of which Enterprise is the issuer.

The purpose of this part is to:

(a) Enhance liquidity in the MBS marketplace, and to that end, enable adoption of the UMBS, by achieving sufficient similarity of cash flows on cohorts of TBA-eligible MBS such that investors will accept delivery of UMBS from either issuer in settlement of trades on the TBA market.

(b) Provide transparency and durability into the process for creating alignment.

Each Enterprise's covered programs, policies, and practices must align with the other Enterprise's covered programs, policies, and practices.

(a) When aligning covered programs, policies, and practices, the Enterprises must consider:

(1) The effect of the alignment on TBA-eligible securities' pricing and particularly on the prepayment speeds of mortgages underlying TBA-eligible MBS.

(2) Options that provide the greatest benefit for investors, lenders, and mortgage borrowers.

(b) [Reserved]

When and in the manner instructed by FHFA, the Enterprises shall consult with each other on any issues, including changes to covered programs, policies, and practices that potentially or actually cause cash flows to TBA-eligible MBS investors to misalign. The Enterprises shall report to FHFA on the results of any such consultation.

(a) The Enterprises must report any misalignment to FHFA.

(b) The Enterprises must submit, in a timely manner, a written report to FHFA on any material misalignment describing, at a minimum, the likely cause of material misalignment and the Enterprises' plan to address the material misalignment.

(c) FHFA will temporarily adjust the percentages in the definitions of align, misalignment, and material misalignment, if FHFA determines that market conditions dictate that an adjustment is appropriate.

(1) In adjusting the percentages, FHFA will consider:

(i) The prevailing level and volatility of interest rates;

(ii) The level of credit risk embedded in the Enterprises' TBA-eligible MBS; and

(iii) Such other factors as FHFA may, in consultation with the Enterprises, determine to be appropriate to promote market confidence in the alignment of cash flows to TBA-eligible MBS investors and to foster the efficiency and liquidity of the secondary mortgage market.

(2) FHFA will publicly announce any temporary adjustment to the percentages in the definition of align, misalignment, and material misalignment in a timely manner.

(3) If adjusted percentages remain in effect for six months or more, FHFA will amend this part's definitions by Federal Register Notice, with opportunity for public comment.

(4) Temporarily adjusted percentages will remain in effect until six months after the date on which FHFA announced the temporary adjustment unless within six months of that date—

(i) FHFA announces a reversion to the previously prevailing percentages; or

(ii) FHFA initiates the notice and comment process, in which case the temporary percentages will remain in effect until the conclusion of that process.

(d) FHFA will temporarily adjust the definitions of cohort, fastest paying quartile of a cohort, and specified pools, if FHFA determines that changes in market practices or conditions dictate that an adjustment is appropriate.

(1) In adjusting those definitions, FHFA will consider:

(i) Changes in prevailing market practices related to the identification of specified pools;

(ii) The prevailing interest rates environment;

(iii) Observed relationships between pool characteristics and prepayment behavior of the Enterprises' TBA-eligible MBS; and

(iv) Such other factors as FHFA may, in consultation with the Enterprises, determine to be appropriate to promote market confidence in the alignment of cash flows to TBA-eligible MBS investors and to foster the efficiency and liquidity of the secondary mortgage market.

(2) FHFA will publicly announce any temporary adjustment to the definitions of cohort and specified pools in a timely manner.

(3) If adjusted definitions remain in effect for six months or more, FHFA will amend this part's definitions by Federal Register Notice, with opportunity for public comment.

(4) Temporarily adjusted definitions will remain in place until six months after the date on which FHFA announced the temporary adjustment unless within six months of that date—

(i) FHFA announces a reversion to the previously prevailing definitions; or

(ii) FHFA initiates the notice and comment process, in which case the temporary definitions will remain in effect until the conclusion of that process.

(a) Enterprise Change Management Processes. Each Enterprise must establish and maintain an Enterprise-wide governance process to ensure that any proposed changes to covered programs, policies, and practices that may cause misalignment are identified, reviewed, escalated, and submitted, in writing, to FHFA for review and approval in a timely manner, including proposed changes to covered programs, policies, and practices that were previously aligned at the direction of FHFA as conservator.

(1) Submissions to FHFA must include projections for prepayment rates and for removals of delinquent loans under a range of interest rate environments and assumptions concerning borrower defaults.

(2) Submissions to FHFA must include an analysis of the impact on borrowers and impact on the fastest paying quartile of each cohort.

(3) Submissions to FHFA must include an analysis of identified risks and may include potential mitigating actions.

(b) Enterprise Monitoring. Any changes to covered programs, policies, and practices that an Enterprise reasonably should identify as having been a likely cause of an unanticipated divergence between Enterprises in the three-month CPR of the same cohort shall be reported promptly to FHFA in writing.

(c) FHFA Monitoring. FHFA will monitor changes to covered programs, policies, and practices for effects on cash flows to TBA-eligible MBS investors.

(a) Based on its review of reports submitted by the Enterprises and reports issued by independent parties, if FHFA determines that there is misalignment, or the risk of misalignment, FHFA may:

(1) Require an Enterprise to undertake additional analysis, monitoring, or reporting to further the purposes of this part.

(2) Require an Enterprise to change covered programs, policies, and practices that FHFA determines conflict with the purposes of this part.

(b) To address material misalignment, FHFA may require additional and expedient Enterprise actions based on:

(1) Consultation with the Enterprises regarding the cause of the material misalignment;

(2) Review of Enterprise compliance with previously agreed upon or FHFA-required actions; and

(3) Review of the effectiveness of such actions to determine whether they are achieving the purpose of this part.

(c) Depending on the severity and cause of any material misalignment, FHFA, in its discretion, may:

(1) Require an Enterprise to terminate a program, policy, or practice; or

(2) Require the competing Enterprise to implement a comparable program, policy, or practice.

(d) When requiring an Enterprise to terminate a program, policy, or practice, or implement a comparable program, policy, or practice, FHFA will consider:

(1) The effect on TBA-eligible securities pricing and particularly on the prepayment speeds of mortgages underlying TBA-eligible MBS; and

(2) The costs borne by and the benefits likely to accrue to investors, lenders, and mortgage borrowers.

FHFA may exclude from the requirements of this part covered programs, policies, or practices of an Enterprise as long as those covered programs, policies, or practices do not affect more than $5 billion in unpaid principal balance of that Enterprises' TBA-eligible MBS.
