Introduction

Fannie Mae is a leading source of financing for mortgages in the United States. Organized as a 

government-sponsored entity (“GSE”), Fannie Mae is a shareholder-owned corporation. We were 

chartered by Congress to provide liquidity and stability to the residential mortgage market and to promote 

access to mortgage credit. Our revenues are primarily driven by guaranty fees we receive for assuming 

the credit risk on loans underlying the mortgage-backed securities we issue. We do not originate loans or 

lend money directly to borrowers. Rather, we work primarily with lenders who originate loans to 

borrowers. We acquire and securitize those loans into mortgage-backed securities that we guarantee 

(which we refer to as Fannie Mae MBS or our MBS).

We manage the risks that arise from our business activities through our enterprise risk management 

program. Our risk management program aims to monitor and manage the following major business risks: 

credit risk, market risk, liquidity and funding risk, and operational risk. These risks can materially 

adversely affect our business, results of operations, financial condition, liquidity, and net worth.

Our risk management program is composed of four inter-related components that are designed to work 

together as a comprehensive risk management system aimed at enhancing our performance: 

• Governance and Organizational Structure; 

• Risk Appetite Framework; 

• Risk Identification, Assessment, Control and Monitoring; and 

• Reporting and Communication Processes.

We manage risk by using the industry standard “three lines of defense” structure:

• First line: Business units and corporate functions—generate, own and manage risks;

• Second line: Enterprise Risk Management (“ERM”), Compliance & Ethics and other risk oversight 

functions—provides independent risk oversight and effective challenge; and

• Third line: Internal Audit—provides independent assurance.

Our Board of Directors and management-level risk committees are also integral to our risk management 

program.

As a GSE, we are subject to the regulatory capital rules issued by the Federal Housing Finance Agency 

(“FHFA”) pursuant to the Federal Housing Enterprises Financial Safety and Soundness Act of 1992, as 

amended, including by the Housing and Economic Recovery Act of 2008 (together, the “GSE Act”). 

The enterprise regulatory capital framework (12 C.F.R. Part 1240) (“ERCF”) establishes minimum capital 

requirements and regulatory capital buffers by capital tier. Under the ERCF, Fannie Mae is required to 

satisfy risk-based capital requirements based on total capital, adjusted total capital, tier 1 capital, and 

common equity tier 1 (“CET1”) capital. In addition to the minimum capital requirements, the ERCF 

establishes regulatory capital buffers. The ERCF requires Fannie Mae to maintain CET1 capital that 

exceeds its risk-based capital requirements by at least the amount of its prescribed capital conservation 

buffer amount (“PCCBA”). If Fannie Mae’s risk-based capital does not exceed its PCCBA, Fannie Mae will 

be subject to limitations on its capital distributions and discretionary bonus payments to executives. The 

PCCBA must be met with CET1 capital. Similarly, the ERCF establishes a leverage capital buffer titled the 

prescribed leverage buffer amount (“PLBA”) requiring Fannie Mae’s tier 1 capital to exceed the PLBA to 

avoid capital or discretionary bonus distribution limitations.

Although the ERCF went into effect in February 2021, Fannie Mae is not required to hold capital 

according to the framework’s requirements until the date of termination of its conservatorship or such later 

date as may be ordered by FHFA. Beginning with this report, Fannie Mae is required to provide timely 

public disclosures each calendar quarter of the information specified in subpart D of the ERCF. 

 Page 5
Fannie Mae’s capital disclosures in this report are not required to be, and have not been, audited by its 

independent registered public accounting firm. Some measures of exposures contained in this report may 

not be consistent with accounting principles generally accepted in the U.S. (“U.S. GAAP”) and may not be 

comparable with measures reported in our Form 10-K for the year ended December 31, 2022 (the “2022

Form 10-K”). 

This report includes forward-looking statements regarding future requirements under the ERCF and our 

intention with respect to future CRT transactions. Actual outcomes could be materially different from what 

is set forth in these forward-looking statements due to a variety of factors, including those described in 

“Forward-Looking Statements” and “Risk Factors” in our 2022 Form 10-K.

 Page 6
1. Capital Structure 

Fannie Mae has a variety of issued and outstanding capital instruments, including common stock, 

preferred stock, qualifying junior preferred stock, and short-term debt and long-term debt (callable 

securities, non-callable securities, fixed/floating rate notes, etc.). For more information about our 

outstanding capital instruments, refer to “Note 7, Short-Term and Long-Term Debt,” “Note 11, Equity,” and 

“Note 12, Regulatory Capital Requirements” in our 2022 Form 10-K.

FHFA has provided guidance on the different tiers and classifications of capital in the ERCF. The 

representative components of regulatory capital under the ERCF are shown below:

“Core capital” is defined in the GSE Act and the ERCF as having four components: outstanding common 

stock, outstanding perpetual noncumulative preferred stock1, paid-in capital, and retained earnings 

(accumulated deficit). “Total capital” is defined in the GSE Act to include core capital, a general allowance 

for foreclosure losses, and other amounts from sources of funds available to absorb losses (that the 

Director of FHFA by regulation determines are appropriate to include in determining total capital). 

The following exhibit provides a summary of Fannie Mae’s capital instruments and reconciliations as of 

December 31, 2022.

 Page 7

 These capital classification measures exclude the funds provided to us by Treasury pursuant to the senior preferred stock 

 purchase agreement, as the senior preferred stock does not qualify as core capital due to its cumulative dividend provisions.

 2. Capital Adequacy

In conjunction with Fannie Mae’s management of and adherence to risk appetite limits, capital 

management is integral to our risk and governance processes. Fannie Mae’s ability to manage capital 

resources under baseline and stress environments supports its capacity to absorb expected and 

unexpected future losses and to carry out its statutory mission. Our capital adequacy assessment process 

informs the capital management actions that we may take to align with our regulatory requirements, 

forecasts, risks, strategic goals, and other business objectives. Additionally, operating under the 

conservatorship of the FHFA affects our business and capital management. For more information on how 

conservatorship impacts us, refer to “Business—Conservatorship and Treasury Agreements—

Conservatorship” and “Risk Factors—GSE and Conservatorship Risk” in our 2022 Form 10-K.

Fannie Mae actively monitors its capital levels as part of the capital adequacy assessment process. 

Periodic capital adequacy monitoring enables the identification and assessment of actual changes and 

potential impacts to capital levels and requirements. The objective of this monitoring process is to 

understand Fannie Mae’s current and forecasted capital levels and requirements.

The dates by which we must comply with the requirements of the ERCF are staggered and largely 

dependent on whether we remain in conservatorship. The minimum capital ratio requirements prescribed 

by the ERCF for CET1, tier 1, and adjusted total capital are 4.5%, 6.0%, and 8.0%, respectively, of riskweighted assets (“RWA”). Under the ERCF, our compliance with the minimum regulatory capital 

requirements will be required by the later of our exit from conservatorship or such later date as may be 

ordered by FHFA. 

For more information on Fannie Mae’s approach to assessing its capital adequacy, refer to 

“Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A)—

Liquidity and Capital Management—Capital Management—Capital Requirements” in our 2022 Form 

10-K.

As of December 31, 2022, our capital levels reflect deficits and were significantly below the levels that will 

be required under the ERCF. For more information about our capital metrics under the ERCF as of 

December 31, 2022, see “MD&A—Liquidity and Capital Management—Capital Management—Capital 

Requirements” and “Note 12, Regulatory Capital Requirements” in our 2022 Form 10-K.

Risk-Weighted Assets

Under the ERCF, Fannie Mae is required to determine its RWA under both a standardized approach and 

an advanced approach; however, the advanced approach requirements are not effective until the later of 

January 1, 2025 or such date provided by an FHFA transition order. Currently, Fannie Mae calculates its 

RWA using the standardized approach set forth in the ERCF. Under the standardized approach, Fannie 

Mae’s total RWA equals the sum of its credit risk, market risk and operational risk RWA.

Our credit risk exposure exists primarily in connection with our guaranty book of business and our 

institutional counterparties. Mortgage credit risk arises from the risk of loss resulting from the failure of a 

borrower to make required mortgage payments. 

Market risk is the risk of loss resulting from changes in the economic environment. Market risk arises from 

fluctuations in interest rates, exchange rates, and other market rates and prices. Market risk includes 

interest-rate risk, which is the risk that movements in interest rates will adversely affect the value of our

 Ratios are calculated as a percentage of risk-weighted assets for risk-based capital metrics and as a percentage of adjusted total 

assets for leverage capital metrics.
assets or liabilities or our future earnings or capital. Market risk also includes spread risk, which is the risk 

from changes in an instrument’s value that relate to factors other than changes in interest rates. We can 

experience losses from changes in the spreads between our mortgage assets and the debt and 

derivatives we use to hedge our position. 

Operational risk is the risk of loss resulting from inadequate or failed internal processes, people, and 

systems, or disruptions from external events.

The following exhibit provides a summary of Fannie Mae’s RWA as of December 31, 2022.

Fannie Mae uses credit risk transfer (“CRT”) transactions to transfer a portion of the credit risk on some of 

the loans in its guaranty book of business to unaffiliated third parties. The credit risk RWA above includes 

the RWA benefit associated with these CRT transactions. These transactions reduce RWA based on the 

structure of the transaction. For more information regarding our CRT transactions, refer to "Section 7, 

Credit Risk Transfers (CRT) and Securitization."

Includes off-balance sheet guarantees, repurchase agreements, off-balance sheet securities lending, and off-balance sheet 

 securities borrowing.
 3. Capital Buffers

The ERCF includes a requirement for Fannie Mae to hold prescribed capital buffers that can be drawn 

down in periods of financial stress and rebuilt over time as economic conditions improve. Our compliance 

with these capital buffers will be required upon exit from conservatorship. In general, once we are 

required to be in compliance with the capital buffers, if Fannie Mae’s capital levels fall below the 

prescribed buffer amounts, it must restrict capital distributions such as stock repurchases and dividends, 

as well as discretionary bonus payments to executives, until the buffer amounts are restored. The stability 

capital buffer, stress capital buffer, and countercyclical capital buffer comprise the PCCBA. The prescribed 

leverage buffer amount (“PLBA”) for 2022 was set at 50% of the 2022 stability capital buffer. Going 

forward, the stability capital buffer and PLBA will be updated with an effective date that depends on 

whether the stability capital buffer increases or decreases relative to the previously calculated value.

For additional information regarding Fannie Mae’s capital buffers, refer to “Business—Legislation and 

Regulation—GSE-Focused Matters—Capital Requirements” in our 2022 Form 10-K. 

The following exhibit presents Fannie Mae’s PCCBA, PLBA, eligible retained income, and maximum 

payout ratio as of December 31, 2022.

 Page 13

10 The stress capital buffer is calculated by multiplying prescribed factors by adjusted total assets as of the last day of the previous 

calendar quarter.

11 The 2022 stability capital buffer is calculated by multiplying a factor determined based on our share of mortgage debt outstanding 

 by adjusted total assets as of December 31, 2020.

12 The countercyclical capital buffer is calculated by multiplying prescribed factors by adjusted total assets as of the last day of the

 previous calendar quarter.

13 Eligible retained income is the greater of: (1) net income for the four preceding calendar quarters, net of distributions and 

 associated tax effects not already reflected in net income and (2) average of our net income over the preceding four quarters.
 4. Credit Risk: General Disclosures 

Credit risk is the risk of loss arising from another party’s failure to meet its contractual obligations. For 

financial securities or instruments, credit risk is the risk of not receiving principal, interest, or other 

financial obligation on a timely basis. Our credit risk exposure exists primarily in connection with our 

guaranty book of business and our institutional counterparties. 

The components of our credit risk management program are implemented by our first line-of-defense risk 

managers, procedures and controls that identify, manage and mitigate credit risk. We have business 

Credit Risk Officers (“CROs”) in our ERM Division acting in a second-line function. For more information 

on credit risk management, credit risk-related policies, exposures, and derivatives see the following 

referenced sections in our 2022 Form 10-K.

5. Counterparty Credit Risk

Institutional counterparty credit risk is the risk of loss resulting from the failure of an institutional 

counterparty to fulfill its contractual obligations to us. Our primary exposure to institutional counterparty 

credit risk exists with our: 

• credit guarantors, including mortgage insurers, reinsurers and multifamily lenders with risk 

sharing arrangements;

• mortgage sellers and servicers; and

• financial institutions that issue investments included in our other investments portfolio.

We also have counterparty exposure to: derivatives counterparties; custodial depository institutions; 

mortgage originators, investors and dealers; debt security dealers; central counterparty clearing 

institutions; and document custodians.

We routinely enter into a high volume of transactions with counterparties in the financial services industry 

resulting in a significant credit concentration with respect to this industry. We also may have multiple 

exposures to particular counterparties, as many of our institutional counterparties perform several types of 

services for us. Accordingly, if one of these counterparties were to become insolvent or otherwise default 

on its obligations to us, it could harm our business and financial results in a variety of ways. Our overall 

objective in managing institutional counterparty credit risk is to maintain individual and portfolio-level 

counterparty exposures within acceptable ranges based on our risk-based rating system. We seek to 

achieve this objective through the following:

• establishment and observance of counterparty eligibility standards appropriate to each exposure 

type and level; 

• establishment of risk limits;

• requiring collateralization of exposures where appropriate; and

• exposure monitoring and management.

Counterparty Credit Limits – For a discussion of how we establish risk limits for counterparty credit 

exposures, refer to “MD&A—Risk Management—Institutional Counterparty Credit Risk Management” in 

our 2022 Form 10-K. Fannie Mae also has established processes for the management, identification, and 

valuation of collateral received from or posted by counterparties. 

Principal types of collateral taken include cash and Treasury securities (Treasury Bills less than one year, 

Treasury Notes of varying maturities and floating-rate Treasury bonds), as well as agency mortgagebacked securities, and Ginnie Mae multi-class securities.

Fannie Mae’s collateral requirements vary based on the provisions present within individual agreements. 

Under many of our International Swaps and Derivatives Association (“ISDA”) agreements, in the event of 

a counterparty credit downgrade the posted collateral is subject to an additional collateral haircut. 

Additionally, if the counterparty credit rating is downgraded to a certain level, the party that has not been 

downgraded maintains the ability to terminate all trades. 

We account for certain forms of credit risk transfer transactions as derivatives. For more information on 

our derivative transactions, refer to “Note 8, Derivative Instruments” in our 2022 Form 10-K.

22 Represents fair value of derivatives associated with risk sharing programs.

23 Represents reverse repurchase agreements, excluding reverse repurchase agreements classified as cash equivalents.
 6. Credit Risk Mitigation 

We enter into various arrangements to mitigate credit risk. In connection with these arrangements, we 

pledge and accept collateral to reduce potential credit risk exposure. For a discussion of our credit risk 

mitigation practices regarding collateral valuation and the types of collateral engaged, see “Note 1, 

Summary of Significant Accounting Policies—Collateral” in our 2022 Form 10-K.

We rely on our institutional counterparties to provide services and credit enhancements that are critical to 

our business. For more information on the guarantors and other providers of credit risk mitigation that we 

engage, see “MD&A—Risk Management—Institutional Counterparty Credit Risk Management,” “MD&A— 

Single-Family Business—Single-Family Mortgage Credit Risk Management,” “MD&A—Multifamily 

Business—Multifamily Mortgage Credit Risk Management,” and “Note 13, Concentrations of Credit Risk” 

in our 2022 Form 10-K.

Our charter generally requires credit enhancement on conventional single-family mortgage loans we 

acquire with a loan-to-value ratio over 80%. This requirement is usually met by the provision of private 

mortgage insurance from one of six mortgage insurance providers. Eligibility standards for mortgage 

insurers are established under private mortgage insurer eligibility requirements and exposure 

concentrations managed via counterparty limit monitoring. The financial ability and willingness of our 

approved mortgage insurers to pay claims is an important determinant of our overall credit risk exposure.

CRT transactions provide another form of credit risk mitigation. We manage the concentration, market, 

and counterparty risks associated with CRT transactions through back-end CRT deal structures, including 

Connecticut Avenue Securities® (“CAS”) issuances and reinsurance transactions, as well as counterparty 

risk requirements and collateral requirements. For additional information on counterparty risk and 

collateral refer to “Section 5, Counterparty Credit Risk.”

Collateral levels for repurchase agreement transactions are consistent with the ERCF requirements and 

are detailed in the exhibit below as of December 31, 2022.

With the exception of mortgage insurance and CRT exposures, Fannie Mae does not have any other 

exposures whose credit risk is mitigated by eligible guarantees or credit derivatives obtained from 

external third parties. Fannie Mae’s exposure to mortgage and other insurers is discussed in “Section 5, 

Counterparty Credit Risk” of this report.

transfer transactions.

25 Exhibit excludes multifamily loans for which lenders have posted $1,175 million collateral pre-haircut and $1,145 million 

 collateral post-haircut.
 7. Credit Risk Transfers and Securitization 

One of the key components of our credit risk management strategy is the transfer of mortgage credit risk 

to third parties. Credit risk transfer transactions, including CAS issuances, generally transfer a portion of 

credit losses on a reference pool of mortgage loans to investors. We also use Credit Insurance Risk 

TransferTM (“CIRTTM”) deals to transfer a portion of the credit risk on a pool of loans to an insurance 

provider that retains the risk, or to an insurance provider that simultaneously cedes all of its risk to one or 

more reinsurers.

For more information on Fannie Mae’s credit risk management strategy regarding CRTs, see “Business —

Managing Mortgage Credit Risk—Sharing and Selling Credit Risk,” “MD&A—Single-Family Business—

Single-Family Mortgage Credit Risk Management—Single-Family Credit Enhancement and Transfer of 

Mortgage Credit Risk,” and “MD&A—Multifamily Business—Multifamily Mortgage Credit Risk 

Management—Transfer of Multifamily Mortgage Credit Risk” in our 2022 Form 10-K.

Fannie Mae’s issuance of CRT securities does not create any new mortgage credit exposure for Fannie 

Mae, since Fannie Mae already guarantees the loans in the underlying reference pools. CRT transactions 

are designed to reduce our mortgage credit risk by transferring a portion of our single-family and 

multifamily mortgage credit risk on reference pools of mortgage loans to the private market. CIRT 

transactions do give rise to incremental counterparty credit risk, which reduces the capital relief provided 

by the transactions, because Fannie Mae is subject to the risk that the CIRT counterparties (insurers and 

reinsurers) may not meet their payment obligations to us following a credit loss event; CAS transactions, 

however, do not give rise to incremental counterparty credit risk. All CRT transactions have model, pricing, 

and structuring risks given their inherent complexity. 

The metrics used to measure the interest-rate and spread securitization exposures of CRT transactions 

are generated using internal models. Our internal models, consistent with standard practice for models 

used in our industry, require numerous assumptions. There are inherent limitations in any methodology 

used to estimate the exposure to changes in interest rates for transactions where CRT is applied. The 

reliability of our prepayment estimates and interest-rate risk metrics depends on the availability and 

quality of historical data for each of the types of securities in our net portfolio. When market conditions 

change rapidly and dramatically, the assumptions of our models may no longer accurately capture or 

reflect the changing conditions. On a regular basis, management makes judgments about the 

appropriateness of the risk assessments indicated by the models. For more information on our models, 

see “MD&A—Risk Management—Operational Risk Management—Model Risk Management” and “Risk 

Factors—Operational Risk” in our 2022 Form 10-K.

For a discussion of how Fannie Mae mitigates mortgage credit risk retained through securitization 

exposures, see “Business—Managing Mortgage Credit Risk,” “MD&A—Single-Family Business—SingleFamily Mortgage Credit Risk Management,” “MD&A—Multifamily Business—Multifamily Mortgage Credit 

Risk Management,” and “MD&A—Risk Management—Institutional Counterparty Credit Risk 

Management” in our 2022 Form 10-K.

Special Purpose Entities (“SPEs”) used to Securitize Third-Party Exposures – For information on 

the type of securitization SPEs that Fannie Mae, as sponsor, uses to securitize third-party exposures, see 

“Note 2, Consolidations and Transfers of Financial Assets” in our 2022 Form 10-K.

Fannie Mae does not have any affiliated entities that it manages or advises that invest either in the 

securitization exposures that Fannie Mae has securitized or in securitization SPEs that the company 

sponsors.

CRT Processes – For information on Fannie Mae’s CRT processes, see “MD&A—Single-Family 

Business—Single-Family Mortgage Credit Risk Management—Single-Family Credit Enhancement and 

Transfer of Mortgage Credit Risk” and “MD&A—Multifamily Business—Multifamily Mortgage Credit Risk 

 Page 20
Management—Transfer of Multifamily Mortgage Credit Risk” in our 2022 Form 10-K. In addition, for 

information regarding the methods and key assumptions applied in valuing retained or purchased 

interests, treatment of synthetic securitizations, and recognizing liabilities on the balance sheet for 

arrangements that could require the company to provide financial support for securitized assets, see 

“Note 1, Summary of Significant Accounting Policies—Investments in Securities,” “Note 2, Consolidations 

and Transfers of Financial Assets—Types of VIEs —SPVs Associated with our Credit Risk Transfer 

Programs,” and “Note 6, Financial Guarantees” in our 2022 Form 10-K.

Fannie Mae’s CRT exposures are off-balance sheet assets. As the reference pool loans remain on Fannie 

Mae’s balance sheet, there is no sale associated with the issuance of the accompanying securities (i.e., 

for CAS) or reinsurance (CIRT deals). The assessment and valuation of a CRT transaction does not result 

in the recognition of retained or purchased interest nor any gain-on-sale. We do not have any creditenhancing interest-only strip CRT-related exposures assigned 1,250% risk weights. Additionally, the 

process for valuing exposures intended to be securitized through CRT transactions is the same as the 

process for valuing other exposures.

For private-label securitization and other non-CRT securitization exposures, we utilize the Simplified 

Supervisory Formula Approach (“SSFA”) for calculating RWA. For CRT exposures, we utilize the Credit 

Risk Transfer Approach (“CRTA”) for calculating RWA.

We perform regular evaluations and assessments of our CRT objectives, risks, processes, and policies.

The following exhibit sets forth our CRT exposures, their related exposure amounts, retained and 

acquired breakout, and past due and recognized loss amounts, as of December 31, 2022.

 8. Equities

We account for securities we have acquired as either trading or available-for-sale (“AFS”). We measure 

trading securities at fair value in our consolidated balance sheets with unrealized and realized gains and 

losses included as a component of “Fair value gains (losses), net” in our consolidated statements of 

operations and comprehensive income. 

We adhere to U.S. GAAP to guide our determination of each pricing approach and primarily use 

independent pricing sources. Vendor pricing is generally our preferred method for pricing assets and 

liabilities, which enables us to leverage and validate pricing information from multiple independent 

sources. To corroborate results, we subject vendor prices to stringent testing by pricing teams. When 

vendor pricing is not available or appropriate, we use either an internal method based on market 

observable data or pricing models. Models used for financial reporting purposes must be approved by our 

independent model risk management team within our Enterprise Risk Management division prior to use. 

Additionally, our internal pricing teams conduct regular model assessments to determine whether models 

are still reasonable and appropriate for their intended business purposes. 

For information regarding the types/nature of our equity investments, the carrying and fair value of the 

investments, refer to the “Consolidated Balance Sheets” and the “Consolidated Statements of Operations 

and Comprehensive Income” in our 2022 Form 10-K.

sale of AFS securities in “Investment gains (losses), net” in our consolidated statements of operations and 

comprehensive income. We define the amortized cost basis of our AFS securities as unpaid principal 

balance, net of unamortized premiums and discounts, and other cost basis adjustments. For a breakout of 

the total unrealized gains and losses recognized on our consolidated balance sheet but not through 

earnings, see “Note 5, Investments in Securities—Available-for-Sale Securities” in our 2022 Form 10-K.

 9. Interest Rate Risk for Non-Trading Activities

We are subject to interest-rate risk, which is the risk that movements in interest rates will adversely affect 

the value of our assets or liabilities or our future earnings or capital. Our exposure to interest-rate risk 

primarily arises from two sources: (1) our “net portfolio,” which we define as: our retained mortgage 

portfolio assets, other investments portfolio, outstanding debt of Fannie Mae used to fund the retained 

mortgage portfolio assets and other investments portfolio, mortgage commitments and risk management 

derivatives; and (2) our consolidated MBS trusts. 

For general derivatives activities, we use a wide range of Futures Commission Merchants and receive 

and pledge collateral to address market concentration and counterparty risk management requirements. 

These risks include counterparty default risk and market risks. 

For more information on the nature of interest rate risk for non-trading activities, and the key assumptions 

used, see “MD&A—Key Market Economic Indicators—How Interest Rates Can Affect Our Financial 

Results” and “MD&A—Risk Management—Market Risk Management, including Interest-Rate Risk 

Management” in our 2022 Form 10-K.

For information on Fannie Mae’s market value sensitivity based on interest-rate shocks, see “MD&A—

Risk Management—Market Risk Management, including Interest-Rate Risk Management—Measurement 

of Interest-Rate Risk” in our 2022 Form 10-K. 

 Page 27
 10. Operational Risk 

Operational risk is the risk of loss resulting from inadequate or failed internal processes, people, and 

systems or disruptions from external events. For information on the operational risks we face and how we 

identify, monitor, and manage these risks (including cybersecurity risks), see “Risk Factors—Operational 

Risk” and “MD&A—Risk Management—Operational Risk Management” in our 2022 Form 10-K.

As previously discussed, Fannie Mae calculates its RWA using the standardized approach, whereby 

operational risk RWA is calculated by multiplying adjusted total assets by 15 basis points, and then 

multiplying by 12.5. 

For information on how insurance is used to mitigate operational risk, see “Risk Factors—Operational 

Risk” and “MD&A—Risk Management—Operational Risk Management” in our 2022 Form 10-K.

 11. Tier 1 Leverage Ratio 

The ERCF requires Fannie Mae to maintain tier 1 capital in excess of the amount required under its tier 1 

leverage ratio34 requirement by at least the amount of its PLBA. The leverage ratio requirement measures 

the amount of tier 1 capital relative to Fannie Mae’s adjusted total assets. The following exhibit provides a 

view of Fannie Mae’s adjusted total assets and tier 1 leverage as of December 31, 2022.

 12. Market Risk

We are subject to market risk, which includes interest-rate risk and spread risk. These risks arise primarily 

from our mortgage asset investments. Interest-rate risk is the risk that movements in interest rates will 

adversely affect the value of our assets or liabilities or our future earnings or capital. Spread risk is the 

risk from changes in an instrument’s value that relate to factors other than changes in interest rates. We 

can experience losses from changes in the spreads between our mortgage assets and the debt and 

derivatives we use to hedge our position.

We monitor current market conditions, including the interest-rate environment, to assess the impact of 

these conditions on individual positions and our interest-rate risk profile. In addition to qualitative factors, 

we use various quantitative risk metrics in determining the appropriate composition of our retained 

mortgage portfolio, our investments in non-mortgage securities and relative mix of debt and derivatives 

positions to remain within pre-defined risk tolerance levels that we consider acceptable. We regularly 

disclose two interest-rate risk metrics that estimate our interest-rate exposure: (1) fair value sensitivity to 

changes in interest-rate levels and the slope of the yield curve and (2) duration gap.

We calculate market risk RWA under the standardized approach in the ERCF. We use one of the following 

three approaches depending principally on instrument type: (1) a single-point approach used for 

instruments primarily with credit risk only; (2) a spread duration approach for instruments with additional 

spread and prepayment risk; or (3) an internal models approach for instruments with spread risk not 

included in the previous two categories, such as commercial mortgage-backed securities (“CMBS”), 

single-family agency securities, and Ginnie Mae mortgage-backed securities.

Fannie Mae’s valuation framework incorporates key elements for governance, methodology, valuation 

adjustments, and model validation.

Valuation governance provides: (1) an overview of governance bodies and committees; (2) an outline of 

the structure emphasizing independence of the valuation review process; (3) detail on governance 

processes and financial instruments covered; and (4) the end-to-end valuation process, including the 

control framework and roles and responsibilities for first and second lines of defense in the valuation 

processes. For more information on Fannie Mae's valuation techniques, refer to “Note 15, Fair Value—

Fair Value Measurement” in our 2022 Form 10-K.

The internal model approach is intended to capture at a granular level the risk associated with changes in 

the discounting spread used to value the future cash flows of the assets in our retained mortgage 

portfolio. The future cash flows are projected by models that reflect the expected prepayment behavior 

associated with the different characteristics of the assets (amortization terms, vintages, mortgage rates, 

etc.) in our current economic outlook. However, internal models do not incorporate basis risk36 across 

positions.

Consistent with our model risk management framework, regulatory expectations and industry practice, an 

independent second line model risk function subjects our material market risk models to rigorous 

validation testing for conceptual soundness and fitness for use.

The calculation of market risk capital for our net portfolio quantifies the amount of market value losses 

that its assets could experience under spread widening consistent with the size of the spread movements 

observed during the recession of 2008, assuming that other risk factors such as benchmark interest rates, 

mortgage rates, and home prices remain the same as in the current economic outlook.

Per our model risk management framework and policies, relevant market risk models using internalderived models are subject to model performance management to ensure conformance between model 

estimates and actual portfolio value changes.

The metrics used to measure our interest-rate exposure are generated using internal models. Our internal 

models, consistent with standard practice for models used in our industry, require numerous assumptions. 

There are inherent limitations in any methodology used to estimate the exposure to changes in market 

interest rates. The reliability of our prepayment estimates and interest-rate risk metrics depends on the 

availability and quality of historical data for each of the types of securities in our net portfolio. When 

market conditions change rapidly and dramatically, the assumptions of our models may no longer 

accurately capture or reflect the changing conditions. On a regular basis, management makes judgments 

about the appropriateness of the risk assessments indicated by the models. For more information on our 

models, see “MD&A—Risk Management—Operational Risk Management—Model Risk Management” and

“Risk Factors—Operational Risk” in our 2022 Form 10-K.

The metrics used to measure the interest-rate and spread exposure of re-securitization positions are 

generated using internal models in combination with external models that project how the securitization 

cash flows are allocated to the re-securitization positions.

 position.
