Capital, (Risk-Based Capital Regulation). The amendments are intended 
to enhance the accuracy and transparency of the calculation of the 
risk-based capital requirement for Fannie Mae and Freddie Mac (the 
Enterprises) and to update the Risk-Based Capital Regulation to 
incorporate approved new activities treatments.

EFFECTIVE DATE: December 14, 2006.

SUPPLEMENTARY INFORMATION:

Background

    Title XIII of the Housing and Community Development Act of 1992, 
Pub. L. 102-550, titled the Federal Housing Enterprise Financial Safety 
and Soundness Act of 1992 (12 U.S.C. 4501 et seq.), established OFHEO 
as an independent office within the Department of Housing and Urban 
Development to ensure that the Federal National Mortgage Association 
(Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie 
Mac) (collectively, the Enterprises) are adequately capitalized, 
operate safely and soundly, and comply with applicable laws, rules and 
regulations.
    In furtherance of its regulatory responsibilities, OFHEO published 
a final regulation setting forth a risk-based capital test which forms 
the basis for determining the risk-based capital requirement for each 
Enterprise.\1\ The Risk-Based Capital Regulation has been amended to 
incorporate corrective and technical amendments that enhance the 
accuracy and transparency of the calculation of the risk-based capital 
requirement.\2\

(April 19, 2002), 68 FR 7309 (February 13, 2003).
---------------------------------------------------------------------------

    Since the last amendment to the Risk Based Capital Regulation, 
additional experience with the regulation raised further operational 
and technical issues. On June 26, 2006, at 71 FR 36231, OFHEO published 
a proposed notice of rulemaking (NPRM) for comment to incorporate a 
number of technical amendments to the Risk-Based Capital Regulation. 
The NPRM proposed amending the Risk-Based Capital Regulation to 
incorporate additional interest rate indices, clarify definitions, 
integrate Enterprise new activities and update treatment of certain 
mark-to-market accounting issues. As stated in the NPRM, the proposed 
amendments are capital neutral and largely codify existing practice 
pursuant to the current Risk-Based Capital Regulation.
    The 30-day comment period ended July 26, 2006. All comments 
received have been made available to the public in the OFHEO Public 
Reading Room and also posted on the OFHEO Web site at http://OFHEO.gov.

Comments Received

    Comments were received from the Consumer Mortgage Coalition (CMC), 
a trade group of national residential mortgage lenders; FM Policy 
Focus, a coalition of financial services and housing-related trade 
associations; the Mortgage Insurance Companies of America (MICA); the 
Mortgage Bankers Association (MBA), a national association representing 
the real estate finance industry; Fannie Mae; and Freddie Mac. All 
comments were taken into consideration. Significant comments related to 
the proposed regulation are discussed below.

Purpose and Scope

    All of the commenters expressed support for OFHEO's decision to 
revise the Risk-Based Capital Regulation to address ongoing financial 
and mortgage market developments that impact the risk profiles of the 
Enterprises. Commenters also supported OFHEO's decision to provide 
notice and opportunity to comment on the proposed changes, 
notwithstanding their technical nature and capital neutrality.
    As noted in the comments, the Risk-Based Capital Regulation should 
be revised periodically to respond to developments in the mortgage 
markets, address technical issues, and respond to new Enterprise 
activities. The technical changes proposed by OFHEO are in furtherance 
of its regulatory duties and enhance both the accuracy and transparency 
of the Risk-Based Capital Regulation. For these reasons, and the 
discussions that follow, OFHEO has determined to issue the amendments 
as discussed below.

Additional Interest Rate Indices

    Due to developments in the mortgage and financial markets since the 
promulgation of the Risk-Based Capital Regulation and the introduction 
of a number of approved new activities at each Enterprise, OFHEO 
proposed incorporating additions to the interest rate indices used to 
measure Enterprise risk. OFHEO proposed the incorporation of the new 
indices through revisions to Table ``3-18, Interest Rate and Index 
Inputs,'' and Table ``3-27, Non-Treasury Interest Rates,'' of Appendix 
A to Subpart B of the Risk-Based Capital Regulation. The new interest 
rate indices are the Constant Maturity Mortgage Index, 12 month Moving 
Treasury Average, One month Freddie Mac Reference Bill, Certificate of 
Deposits Index, 2 Year Swap, 3 Year Swap, 5 Year Swap, 10 Year Swap and 
30 Year Swap. All of the commenters addressing this issue supported the 
adoption of the proposed interest rate indices used to measure more 
accurately

[[Page 75086]]

Enterprise risk. OFHEO has determined to adopt the amendments as 
proposed.

Revised Risk-Based Capital Regulation Definitions

    As stated in the NPRM, additional operational experience with the 
Risk-Based Capital Regulation, as well as financial and mortgage market 
developments, motivated OFHEO to refine a number of defined terms in 
the regulation. Proposed amendments include changes to recognize that 
single family loans with interest-only periods have become common and 
that the Enterprises have guaranteed or acquired such loans. Sections 
3.1.2.1, 3.6.3.3.1 and 3.6.3.3.3 of the appendix to the Risk-Based 
Capital Regulation currently provide a treatment for interest-only 
periods. However, sections 3.1.2.1, 3.6.3.3.1, and 3.6.3.3.2 currently 
assume that only multi-family loans have this feature. OFHEO's proposed 
amendments would adopt the changes necessary to accommodate single-
family interest-only loans. In addition to the single-family interest-
only issue, OFHEO proposed amendments to the definition of ``float-
days'' in sections 3.1.2.1.1 and 3.6.3.7.2 to improve the accuracy of 
that definition. Finally, an additional number of definitions 
throughout the Risk-Based Capital Regulation were revised to ensure 
consistency and accuracy. All of the commenters that addressed this 
issue supported the adoption of the proposed amendments. OFHEO has 
determined to adopt the amendments as proposed.

Incorporation of New Enterprise Activities

    Risk-Based Capital Regulation Section 3.11.3, Treatment of New 
Activities, sets forth the procedures by which new Enterprise 
activities are reported to OFHEO and analyzed by OFHEO to determine an 
appropriately conservative treatment to be incorporated into the risk-
based capital calculation. The section also describes how any newly 
incorporated treatment is made available for public comment and 
possible further revision. The subheadings below describe the responses 
to comments received on new Enterprise activities.
a. Reverse Mortgages
    OFHEO proposed revisions to Section 3.6.3.3.1 of the Risk-Based 
Capital Regulation to incorporate an appropriate treatment for reverse 
mortgages. Freddie Mac commented that the proposed treatment for 
reverse mortgages was operationally complex and that it did not 
accurately tie capital to risk. Freddie Mac also noted in its comments 
that it does not currently purchase or guarantee reverse mortgages. 
Freddie Mac suggested that it may propose an alternative treatment in 
the future if it ever purchases or guarantees reverse mortgages. Fannie 
Mae commented that the proposed treatment was ``insufficiently robust 
with regard to accuracy.'' Fannie Mae did not provide an alternative 
treatment. OFHEO considered both comments and determined that, in the 
absence of suggested alternative treatments or additional information 
that would support development of an alternative treatment, it would 
adopt the provision as proposed.
b. Futures and Options on Futures
    OFHEO proposed technical amendments to Section 3.8 of the Risk-
Based Capital Regulation to address treatments for futures and for 
options on futures. OFHEO's treatment specifies a multi-step process 
for modeling futures and options on futures. Freddie Mac agreed with 
the treatment for futures but suggested a better approach to modeling 
futures options would be to utilize the strike price in the calculation 
of the cash settlement amount. The comments did not provide an 
alternative treatment or additional supporting data. OFHEO considered 
Freddie Mac's comments; however, in the absence of additional data, and 
given OFHEO's favorable experience with the proposed method, OFHEO has 
determined to adopt the amendment as proposed.
c. Split-Rate Adjustable Rate Mortgages
    OFHEO proposed a new activities treatment for split rate adjustable 
rate mortgages in Section 3.6 of the Risk-Based Capital Regulation. The 
proposed treatment ignores the split-rate feature and treats split-rate 
ARMs as traditional ARMs. Fannie Mae commented that the treatment was 
``insufficiently robust.'' Fannie Mae did not propose an alternative 
treatment. OFHEO considered the comment, and, in the absence of an 
alternative treatment that improves upon the accuracy or transparency 
of the OFHEO proposal, determined to adopt the amendment as proposed.
d. CPI-Linked Floating Rate Instruments
    OFHEO proposed incorporating a treatment for CPI-linked floating 
rate instruments in Section 3.8 of the Risk-Based Capital Regulation. 
Unlike interest rates, the stress test does not project the CPI. 
Enterprise issuance of CPI-linked instruments is tied to swap market 
transactions intended to create desired synthetic debt structure and 
terms. In such cases, the true economic position nets to the payment 
terms of the related derivative contract. OFHEO proposed a treatment 
where the net synthetic position is evaluated, whereby the Enterprises 
would substitute the CPI-linked instrument's coupon payment terms with 
those of the related swap contract. Fannie Mae commented that the 
treatment was incomplete and should not be incorporated into the 
regulation. Fannie Mae did not propose an alternative treatment. 
OFHEO's proposed treatment provides a transparent and accurate method 
to assess the impact of these instruments on the risk profiles of the 
Enterprises. OFHEO has determined to adopt the amendment as proposed.

Update of Mark-to-Market Accounting Treatment

    Since the adoption of the Risk-Based Capital Regulation, the 
Financial Accounting Standards Board has adopted a number of new 
accounting standards that introduce fair values to the balance sheet 
and that are similar in complexity to FAS 115 and FAS 133. OFHEO 
proposed a technical amendment to Section 3.10.3.6.2 [a][1] of the 
Risk-Based Capital Regulation that would extend the current risk-based 
capital regulatory treatment of FAS 115 and FAS 133 to other accounting 
standards that require mark-to-market accounting. Freddie Mac offered 
several comments regarding the proposed amendments that clarify the 
scope of the proposed treatment for fair values. Freddie Mac's proposed 
language clarifies that applicable fair value standards will apply only 
to amounts that are measured at fair value, not to other amounts 
mentioned in such standards, and that amounts not measured at fair 
value are represented by and presented according to GAAP. OFHEO agrees 
that the language proposed by Freddie Mac will enhance the transparency 
and accuracy of the treatment and has amended the provision 
accordingly.
    Fannie Mae's comment regarding Section 3.10.3.6.2.[a] 1. b. 1) 
requested permission to estimate amortized cost basis when implementing 
applicable fair value standards in order to obviate the maintenance of 
amortized cost basis information if GAAP no longer requires it. Fannie 
Mae did not provide an analysis of the impact, savings, applicability 
or scope of its suggested change. When and if GAAP changes as described 
by Fannie Mae arise, an alternative treatment could be adopted via an 
appropriate regulatory method. Thus, OFHEO has determined not to 
incorporate Fannie Mae's comment.

[[Page 75087]]

Other Comments

    Commenters also addressed matters beyond the scope of the NPRM.
    CMC suggested that OFHEO implement a new regulation mandating a 
scenario analysis of Enterprise capital to supplement the current 
analysis performed under the Risk-Based Capital Regulation. CMC 
suggested that OFHEO develop the alternative scenarios after a notice 
and comment procedure and a public hearing. This comment was beyond the 
scope of the NPRM and has not been considered in the current 
rulemaking.
    FM Policy Watch raised concerns regarding the transparency and 
effectiveness of the new activities provisions of the Risk-Based 
Capital Regulation. FM Policy Watch recommended that OFHEO amend the 
new activities process to allow notice and comment on Enterprise new 
activities prior to their posting on the OFHEO Web site and 
incorporation into the risk-based capital calculation. Although this 
comment is beyond the scope of the current rulemaking, OFHEO notes that 
in addition to posting new activities treatments on the OFHEO Web site, 
new activities treatments are disclosed as part of the public 
information provided with the quarterly capital classification. To 
date, OFHEO has not received any comment on a new activities treatment 
posted on its Web site.
    MICA commented that OFHEO should revise the treatment of loan-to-
value ratios (LTVs) in the Risk Based Capital Regulation from the 
current approach to one that recognizes the combined LTV of all loans 
outstanding on a property. MICA also urged OFHEO to adopt a formal 
process to review the safety and soundness implications of Enterprise 
products, programs and activities. This comment was beyond the scope of 
the NPRM and has not been considered in the current rulemaking.

Regulatory Impacts

Executive Order 12866, Regulatory Planning and Review

    The technical amendments address provisions of the Risk-Based 
Capital Regulation. The technical amendments incorporate new activities 
treatments of the Enterprises adopted in accordance with the Risk-Based 
Capital Regulation, corrections to certain definitions, updates to 
interest-rate indices and to incorporate recognition of accounting rule 
changes adopted since the Risk-Based Capital Regulation was 
promulgated. The technical amendments to the Risk-Based Capital 
Regulation are not classified as an economically significant rule under 
Executive Order 12866 because they do not result in an annual effect on 
the economy of $100 million or more or a major increase in costs or 
prices for consumers, individual industries, Federal, state or local 
government agencies, or geographic regions; or have significant adverse 
effects on competition, employment, investment, productivity, 
innovation, or on the ability of United States-based enterprises to 
compete with foreign-based enterprises in foreign or domestic markets. 
Accordingly, no regulatory impact assessment is required. Nevertheless, 
the technical amendments were submitted to the Office of Management and 
Budget (OMB) for review under the provisions of Executive Order 12866 
as a significant regulatory action.

Executive Order 13132, Federalism

    Executive Order 13132 requires that Executive departments and 
agencies identify regulatory actions that have significant federalism 
implications. A regulation has federalism implications if it has 
substantial direct effects on the states, on the relationship or 
distribution of power between the Federal Government and the states, or 
on the distribution of power and responsibilities among various levels 
of government. The Enterprises are federally chartered entities 
supervised by OFHEO. The technical amendments to the Risk-Based Capital 
Regulation address matters which the Enterprises must comply with for 
Federal regulatory purposes. The technical amendments to the Risk-Based 
Capital Regulation address matters regarding the risk-based capital 
calculation for the Enterprises and therefore do not affect in any 
manner the powers and authorities of any state with respect to the 
Enterprises or alter the distribution of power and responsibilities 
between Federal and state levels of government. Therefore, OFHEO has 
determined that the amendments to the Risk-Based Capital Regulation 
have no federalism implications that warrant preparation of a 
Federalism Assessment in accordance with Executive Order 13132.

Paperwork Reduction Act

    The amendments do not contain any information collection 
requirements that require the approval of OMB under the Paperwork 
Reduction Act (44 U.S.C. 3501 et seq.).

Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires that 
a regulation that has a significant economic impact on a substantial 
number of small entities, small businesses, or small organizations must 
include an initial regulatory flexibility analysis describing the 
regulation's impact on small entities. Such an analysis need not be 
undertaken if the agency has certified that the regulation does not 
have a significant economic impact on a substantial number of small 
entities 5 U.S.C. 605(b). OFHEO has considered the impact of the 
technical amendments to the Risk-Based Capital Regulation under the 
Regulatory Flexibility Act. The General Counsel of OFHEO certifies that 
the technical amendments to the Risk-Based Capital Regulation are not 
likely to have a significant economic impact on a substantial number of 
small business entities because the regulation is applicable only to 
the Enterprises, which are not small entities for purposes of the 
Regulatory Flexibility Act.

7. Reverse Mortgages. In a reverse mortgage, a borrower receives one 
or more payments from the lender and the lender is repaid with a 
lump sum when the borrower dies, sells the property or moves out of 
the home permanently. The stress test models reverse mortgages as a 
ladder of zero-coupon securities:
    a. 11 proxy securities for each reverse mortgage program are 
created.
    b. A 10% conditional payment rate is used to create the zero-
coupon securities that will mature in every year of the stress test. 
The zero-coupon securities are a laddered series of floating-rate 
coupon-bearing accreting bonds with a first payment date at 
maturity.
    c. The 11th zero-coupon security will mature three months after 
the stress test to reflect the 35% of UPB not paid down during the 
stress period.
    d. An OFHEO credit rating equivalent to AAA for the FHA insured 
programs and AA for other reverse mortgage programs is assigned.
8. Split-Rate ARM Loans. In split-rate ARM loans, the principal 
portion of the payment is based on a fixed-rate amortization 
schedule while the interest portion is based on a floating rate 
index. These multifamily loans are available as fully amortizing 
product or with a balloon feature. The stress test model does not 
provide treatment for split-rate ARM loans. Split-rate loans shall 
be treated as ARMs when they are issued without a balloon payment 
feature or as Balloon ARMs when the loans contain a balloon payment 
feature.

    [d] Futures and Options on Futures also require special 
treatment:
1. Settle positions on their expiration dates. Exercise only in-the-
money options (settlement value greater than zero).
2. Settle all contracts for cash
3. Calculate the cash settlement amount--the change in price of a 
contract from the contract trade date to its expiration date. 
Calculate the price on the expiration date based on stress test 
interest rates (or, as necessary, forward rates extrapolated from 
these rates).
4. Amortize amounts received or paid at the expiration date into 
income or expense on a straight-line basis over the life of the 
underlying instrument (in the case of an option on a futures 
contract, the life of the instrument underlying the futures 
contract).
5. Amortize an option premium on a straight-line basis over the life 
of the option. (Amortize any remaining balances upon option 
exercise.)
    [e] Swaptions also require special treatment:
1. Assume swap settlement (i.e., initiation of the underlying swap) 
when a swap option is exercised.
2. Calculate a ``normalized'' fixed-pay coupon by subtracting the 
spread over the index, if any, from the coupon on the fixed-rate 
swap leg.
3. For all exercise types (American, Bermudan, and European), 
consistent with RBC Rule section 3.8.3.7, assume exercise by the 
party holding the swap option if the equivalent maturity Enterprise 
Cost of Funds is more than
    a. 50 basis points above the normalized fixed-pay coupon, for a 
pay-fixed swaption (a call or `payor' swaption), or
    b. 50 basis points below the normalized fixed pay coupon for a 
receive-fixed swaption (a put or `receiver' swaption).
4. Amortize option premiums on a straight-line basis over the option 
term. (Amortize any remaining balances upon option exercise).
    [f] CPI-Linked Instruments also require special treatment. The 
stress test lacks the ability to accommodate floating-rate 
instruments that reset in response to changes in the consumer price 
index (CPI) as published by the Bureau of Labor Statistics. 
Enterprise issuance of CPI-linked instruments is tied to swap market 
transactions intended to create desired synthetic debt structure and 
terms. In such cases, the true economic position nets to the payment 
terms of the related derivative contract. Accordingly, in order to 
accommodate and address the existence of CPI-linked instruments in 
the Enterprises' portfolios, the net synthetic position shall be 
evaluated in the stress test. That is, for CPI-linked instruments 
tied to swap transactions that are formally linked in a hedge 
accounting relationship, the Enterprise should substitute the CPI-
linked instrument's coupon payment terms with those of the related 
swap contract.
    [g] Pre-refunded municipal bonds also require special 
treatments. Pre-refunded municipal bonds are collateralized by 
securities that are structured to fund all the cash flows of the 
refunded municipal bonds until the bonds are callable. Since the 
call date for the bonds, also referred to as the pre-refunded date, 
is a more accurate representation of the payoff date than the 
contractual maturity date of the bonds, the stress test models the 
bonds to mature on the call date.

1. Fair Values
    a. The valuation impact of any Applicable Fair Value Standards 
(AFVS), cumulative from their time of implementation, will be 
reversed out of the starting position data, by debiting any 
accumulated credits, and crediting any accumulated debits.
    (1) AFVS are defined as GAAP pronouncements that require or 
allow fair value measurements, e.g., EITF 99-20, FAS 65, FAS 87, FAS 
115, FAS 133, FAS 140, FAS 149 and FIN 45. Valuation impacts of AVFS 
pertain only to amounts that are measured at fair value and not to 
other amounts that are included in AFVS but are not measured at fair 
value.
    (2) The GAAP pronouncements covered by this treatment are 
subject to OFHEO review. The Enterprises will submit a list of 
standards and pronouncements that are being reversed in their RBC 
Reports.
    b. After reversing the valuation impact of AFVS, any affected 
items are presented as follows:
    (1) If absent the adoption of the AFVS, the affected 
transactions measured at fair value would have been accounted for on 
an amortized cost basis, they are presented as if they had always 
been accounted for on an amortized cost basis. Amounts not measured 
at fair value are represented as specified by GAAP and are presented 
using current GAAP rules.
    (2) To the extent that transactions would not have been 
accounted for on an amortized cost basis, they are accounted for as 
if they were income and expense items.
