We are a stockholder-owned corporation organized and existing under the Federal National Mortgage Association Charter Act (the “Charter Act” or our “charter”). We are a government-sponsored enterprise (“GSE”), and we are subject to government oversight and regulation. Our regulators include the Federal Housing Finance Agency (“FHFA”), the U.S. Department of Housing and Urban Development (“HUD”), the U.S. Securities and Exchange Commission (“SEC”), and the U.S. Department of the Treasury (“Treasury”). The U.S. government does not guarantee our securities or other obligations.

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with the SEC’s instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and note disclosures required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. The accompanying condensed consolidated financial statements include our accounts as well as the accounts of other entities in which we have a controlling financial interest. All intercompany accounts and transactions have been eliminated. To conform to our current period presentation, we have reclassified certain amounts reported in our prior period condensed consolidated financial statements. Results for the three and nine months ended September 30, 2020 may not necessarily be indicative of the results for the year ending December 31, 2020.

Advances to lenders represent our payments of cash in exchange for the receipt of mortgage loans from lenders in a transfer that is accounted for as a secured lending arrangement. These transfers primarily occur when we provide early funding to lenders for loans that they will subsequently either sell to us or securitize into a Fannie Mae MBS that they will deliver to us. Early lender funding advances have terms up to 60 days and earn a short-term market rate of interest. Advances to lenders has been presented as a separate line item for all periods presented as increased mortgage refinance activity resulted in a higher balance at period end. In prior periods, advances to lenders were recorded in “Other assets.”

Freestanding credit enhancements primarily include our Connecticut Avenue Securities® (“CAS”) and Credit Insurance Risk TransferTM (“CIRTTM”) programs, enterprise-paid mortgage insurance (“EPMI”), and certain lender risk-sharing arrangements, including our multifamily Delegated Underwriting and Servicing (“DUS®”) program. We have revised our presentation of the expenses and recoveries associated with these programs as described below.

Credit enhancement expense consists of costs associated with our freestanding credit enhancements. We exclude from this expense costs related to our CAS transactions accounted for as debt instruments and credit risk transfer programs accounted for as derivative instruments. Credit enhancement expense has been presented as a separate line item for all periods presented as these expenses have become a more significant driver of our results of operations. In prior periods, credit enhancement expenses were recorded in “Other expenses, net.”

Change in expected credit enhancement recoveries consists of the change in benefits recognized from our freestanding credit enhancements, including any realized amounts. Benefits, if any, from our CAS, CIRT and EPMI programs previously recorded in “Fee and other income” have been reclassified to “Change in expected credit enhancement recoveries” for all periods presented. Benefits from other lender risk-sharing programs, including our multifamily DUS program, were recorded as a

reduction of credit-related expense in periods prior to 2020. However, with our adoption of the CECL standard on January 1, 2020, benefits from freestanding credit enhancements are no longer recorded as a reduction of credit-related expenses. These benefits from lender risk-sharing have been reclassified into “Change in expected credit enhancement recoveries” on a prospective basis beginning January 1, 2020.

Prior period multifamily yield maintenance fees have been reclassified to conform to the current period presentation. Multifamily yield maintenance fees, or prepayment premiums, are fees that a borrower pays when they prepay their loan. For multifamily loans held in a consolidated trust, a portion of the yield maintenance fee is typically passed through to the holders of the trust certificate. As of January 1, 2020, we classify all yield maintenance fees as interest income. For consolidated loans, the portion of the fee passed through to the certificate holders of the trust is classified as interest expense. Previously, we classified multifamily yield maintenance fees as interest income only when the fee was associated with a loan refinancing, otherwise the fee was classified as fee and other income. The portion of the fees passed through to the certificate holders of the trust were previously classified as interest expense only when the fee was associated with a loan refinancing, otherwise the fee was classified as other expense. The changes in presentation have been applied retrospectively to all periods presented and were immaterial for prior periods.

Preparing condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect our reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the dates of our condensed consolidated financial statements, as well as our reported amounts of revenues and expenses during the reporting periods. Management has made significant estimates in a variety of areas including, but not limited to, the allowance for loan losses. For example, significant uncertainty regarding the expected impacts of the COVID-19 pandemic required substantial management judgment in assessing our allowance for loan losses as of September 30, 2020. Actual results could differ from these estimates.

On September 7, 2008, the Secretary of the Treasury and the Director of FHFA announced several actions taken by Treasury and FHFA regarding Fannie Mae, which included: (1) placing us in conservatorship and (2) the execution of a senior preferred stock purchase agreement by our conservator, on our behalf, and Treasury, pursuant to which we issued to Treasury both senior preferred stock and a warrant to purchase common stock.

Under the Federal Housing Enterprises Financial Safety and Soundness Act of 1992, as amended, including by the Federal Housing Finance Regulatory Reform Act of 2008 (together, the “GSE Act”), the conservator immediately succeeded to (1) all rights, titles, powers and privileges of Fannie Mae, and of any stockholder, officer or director of Fannie Mae with respect to Fannie Mae and its assets, and (2) title to the books, records and assets of any other legal custodian of Fannie Mae. The conservator subsequently issued an order that provided for our Board of Directors to exercise specified authorities. The conservator also provided instructions regarding matters for which conservator decision or notification is required. The conservator retains the authority to amend or withdraw its order and instructions at any time.

The conservator has the power to transfer or sell any asset or liability of Fannie Mae (subject to limitations and post-transfer notice provisions for transfers of qualified financial contracts) without any approval, assignment of rights or consent of any party. However, mortgage loans and mortgage-related assets that have been transferred to a Fannie Mae MBS trust must be held by the conservator for the beneficial owners of the Fannie Mae MBS and cannot be used to satisfy the general creditors of Fannie Mae. Neither the conservatorship nor the terms of our agreements with Treasury change our obligation to make required payments on our debt securities or perform under our mortgage guaranty obligations.

On September 5, 2019, Treasury released a plan to reform the housing finance system. The Treasury Housing Reform Plan (the “Treasury plan”) is far-reaching in scope and could have a significant impact on our structure, our role in the secondary mortgage market, our capitalization, our business and our competitive environment. The Treasury plan includes recommendations relating to ending our conservatorship, amending our senior preferred stock purchase agreement with Treasury, considering additional restrictions and requirements on our business, and many other matters. The Treasury plan recommends that Treasury’s commitment to provide funding under the senior preferred stock purchase agreement should be replaced with legislation that authorizes an explicit, paid-for guarantee backed by the full faith and credit of the Federal Government that is limited to the timely payment of principal and interest on qualifying MBS. The Treasury plan further recommends that, pending legislation, even after conservatorship Treasury should maintain its ongoing commitment to support our single-family and multifamily mortgage-backed securities through the senior preferred stock purchase agreement, as amended as contemplated by the plan.

The conservatorship has no specified termination date and there continues to be significant uncertainty regarding our future, including how long we will continue to exist in our current form, the extent of our role in the market, the level of government support of our business, how long we will be in conservatorship, what form we will have and what ownership interest, if any, our current common and preferred stockholders will hold in us after the conservatorship is terminated and whether we will

Treasury has made a commitment under the senior preferred stock purchase agreement to provide funding to us under certain circumstances if we have a net worth deficit. Pursuant to the senior preferred stock purchase agreement, we have received a total of $119.8 billion from Treasury as of September 30, 2020, and the amount of remaining funding available to us under the agreement was $113.9 billion.

Pursuant to the senior preferred stock purchase agreement, we issued shares of senior preferred stock in 2008. The current dividend provisions of the senior preferred stock provide for quarterly dividends consisting of the amount, if any, by which our net worth as of the end of the immediately preceding fiscal quarter exceeds a $25 billion capital reserve amount. We refer to this as a “net worth sweep” dividend. Because we had a net worth of $16.5 billion as of June 30, 2020, no dividends were payable for the third quarter of 2020. And because we had a net worth of $20.7 billion as of September 30, 2020, no dividends are payable for the fourth quarter of 2020.

The aggregate liquidation preference of the senior preferred stock increased from $135.4 billion as of June 30, 2020 to $138.0 billion as of September 30, 2020 due to the $2.5 billion increase in our net worth during the second quarter of 2020. The aggregate liquidation preference of the senior preferred stock will increase to $142.2 billion as of December 31, 2020 due to the $4.2 billion increase in our net worth during the third quarter of 2020.

Because Treasury holds a warrant to purchase shares of Fannie Mae common stock equal to 79.9% of the total number of shares of Fannie Mae common stock, we and Treasury are deemed related parties. As of September 30, 2020, Treasury held an investment in our senior preferred stock with an aggregate liquidation preference of $138.0 billion. See “Senior Preferred Stock Purchase Agreement and Senior Preferred Stock” above for additional information on transactions under this agreement.

FHFA’s control of both Fannie Mae and Freddie Mac has caused Fannie Mae, FHFA and Freddie Mac to be deemed related parties. Additionally, Fannie Mae and Freddie Mac jointly own Common Securitization Solutions, LLC (“CSS”), a limited liability company created to operate a common securitization platform; as such, CSS is deemed a related party. As a part of our joint ownership, Fannie Mae, Freddie Mac and CSS are parties to a limited liability company agreement that sets forth the overall framework for the joint venture, including Fannie Mae’s and Freddie Mac’s rights and responsibilities as members of CSS. Fannie Mae, Freddie Mac and CSS are also parties to a customer services agreement that sets forth the terms under which CSS provides mortgage securitization services to us and Freddie Mac, including the operation of the common securitization platform as well as an administrative services agreement. CSS operates as a separate company from us and Freddie Mac, with all funding and limited administrative support services and other resources provided to it by us and Freddie Mac through our capital contributions.

In the ordinary course of business, Fannie Mae may purchase and sell securities issued by Treasury and Freddie Mac. These transactions occur on the same terms as those prevailing at the time for comparable transactions with unrelated parties. With our implementation of the Single Security Initiative in June 2019, some of the structured securities we issue are backed in whole or in part by Freddie Mac securities. Additionally, we make regular income tax payments to and receive tax refunds from the Internal Revenue Service (“IRS”), a bureau of Treasury.

Our administrative expenses were reduced by $5 million for the three months ended September 30, 2020 and 2019, and $14 million and $15 million for the nine months ended September 30, 2020 and 2019, respectively, due to reimbursements from Treasury and Freddie Mac for expenses incurred as program administrator for Treasury’s Home Affordable Modification Program and other initiatives under Treasury’s Making Home Affordable Program.

In December 2011, Congress enacted the Temporary Payroll Cut Continuation Act of 2011 (“TCCA”) which, among other provisions, required that we increase our single-family guaranty fees by at least 10 basis points and remit this increase to Treasury. Effective April 1, 2012, we increased the guaranty fee on all single-family residential mortgages delivered to us by 10 basis points. The resulting fee revenue and expense are recorded in “Mortgage loans interest income” and “TCCA fees,” respectively, in our condensed consolidated statements of operations and comprehensive income. In 2020, FHFA provided guidance that we are not required to accrue or remit TCCA fees to Treasury with respect to loans backing MBS trusts that have been delinquent for four months or longer. Once payments on such loans resume, we will resume accrual and remittance to Treasury of the associated TCCA fees on the loans. We recognized $679 million and $613 million in TCCA fees during the three months ended September 30, 2020 and 2019, respectively, and $2.0 billion and $1.8 billion for the nine months ended September 30, 2020 and 2019, respectively, of which $679 million had not been remitted to Treasury as of September 30, 2020.

The GSE Act requires us to set aside certain funding obligations, a portion of which is attributable to Treasury’s Capital Magnet Fund. These funding obligations, recognized in “Other expenses, net” in our condensed consolidated statements of operations and comprehensive income, are measured as the product of 4.2 basis points and the unpaid principal balance of our total new business purchases for the respective period, and 35% of this amount is payable to Treasury’s Capital Magnet Fund. We recognized a total of $59 million and $32 million in “Other expenses, net” for the three months ended September 30, 2020 and 2019, respectively, and $144 million and $68 million for the nine months ended September 30, 2020 and 2019, respectively, in connection with Treasury’s Capital Magnet Fund, of which $144 million has not been remitted as of September 30, 2020.

The GSE Act authorizes FHFA to establish an annual assessment for regulated entities, including Fannie Mae, which is payable on a semi-annual basis (April and October), for FHFA’s costs and expenses, as well as to maintain FHFA’s working capital. We recognized FHFA assessment fees, which are recorded in “Administrative expenses” in our condensed consolidated statements of operations and comprehensive income, of $35 million and $30 million for the three months ended September 30, 2020 and 2019, respectively, and $102 million and $89 million for the nine months ended September 30, 2020 and 2019, respectively.

Our condensed consolidated financial statements include our accounts as well as the accounts of the other entities in which we have a controlling financial interest. All intercompany balances and transactions have been eliminated. The typical condition for a controlling financial interest is ownership of a majority of the voting interests of an entity. A controlling financial interest may also exist in entities through arrangements that do not involve voting interests, such as a variable interest entity (“VIE”).

An available-for-sale (“AFS”) debt security is impaired if the fair value of the investment is less than its amortized cost basis. Credit losses (benefits) on impaired AFS debt securities are recognized through an allowance for credit losses. Credit losses are evaluated on an individual security basis and are limited to the difference between the fair value of the debt security and its amortized cost basis. If we intend to sell a debt security or it is more likely than not that we will be required to sell the debt security before recovery, any allowance for credit losses on the debt security is reversed and the amortized cost basis of the debt security is written down to its fair value.

When we acquire mortgage loans that we intend to sell or securitize via trusts that will not be consolidated, we classify the loans as held for sale (“HFS”). We report the carrying value of HFS loans at the lower of cost or fair value. Any excess of an HFS loan’s cost over its fair value is recognized as a valuation allowance, with changes in the valuation allowance recognized as “Investment gains, net” in our condensed consolidated statements of operations and comprehensive income. We recognize interest income on HFS loans on an accrual basis, unless we determine that the ultimate collection of contractual principal or interest payments in full is not reasonably assured. Purchased premiums, discounts and other cost basis adjustments on HFS loans are deferred upon loan acquisition, included in the cost basis of the loan, and not amortized. We determine any lower of cost or fair value adjustment on HFS loans at an individual loan level.

For nonperforming loans transferred from held for investment (“HFI”) to HFS, based upon a change in our intent, we record the loans at the lower of cost or fair value on the date of transfer. When the fair value of the nonperforming loan is less than its amortized cost, we record a write-off against the allowance for loan losses in an amount equal to the difference between the amortized cost basis and the fair value of the loan. If the amount written off upon transfer exceeds the allowance related to the transferred loan, we record the excess in provision for credit losses. If the amounts written off are less than the allowance related to the loans, we recognize a benefit for credit losses.

Nonperforming loans include both seriously delinquent and reperforming loans, which are loans that were previously delinquent but are performing again because payments on the mortgage loan have become current with or without the use of a loan modification plan. Single-family seriously delinquent loans are loans that are 90 days or more past due or in the foreclosure process. Multifamily seriously delinquent loans are loans that are 60 days or more past due.

In the event that we reclassify a performing loan from HFI to HFS, based upon a change in our intent, the allowance for loan losses previously recorded on the HFI mortgage loan is reversed through earnings at the time of reclassification. The mortgage loan is reclassified into HFS at its amortized cost basis and a valuation allowance is established to the extent that the amortized cost basis of the loan exceeds its fair value. The initial recognition of the valuation allowance and any subsequent changes are recorded as a gain or loss in “Investment gains, net.”

When we acquire mortgage loans that we have the ability and the intent to hold for the foreseeable future or until maturity, we classify the loans as HFI. When we consolidate a securitization trust, we recognize the loans underlying the trust in our condensed consolidated balance sheets. The trusts do not have the ability to sell mortgage loans and the use of such loans is limited exclusively to the settlement of obligations of the trusts. Therefore, mortgage loans acquired when we have the intent to securitize via consolidated trusts are generally classified as HFI in our condensed consolidated balance sheets both prior to and subsequent to their securitization.

We report the carrying value of HFI loans at the unpaid principal balance, net of unamortized premiums and discounts, other cost basis adjustments, and allowance for loan losses. We define the amortized cost of HFI loans as unpaid principal balance and accrued interest receivable, net, including any unamortized premiums, discounts, and other cost basis adjustments. For purposes of our condensed consolidated balance sheets, we present accrued interest receivable separately from the amortized cost of our loans held for investment. We recognize interest income on HFI loans on an accrual basis using the effective yield method over the contractual life of the loan, including the amortization of any deferred cost basis adjustments, such as the premium or discount at acquisition, unless we determine that the ultimate collection of contractual principal or interest payments in full is not reasonably assured.

For loans not subject to the COVID-19-related nonaccrual guidance, we discontinue accruing interest on loans when we believe collectability of principal or interest is not reasonably assured, which for a single-family loan we have determined, based on our historical experience, to be when the loan becomes two months or more past due according to its contractual terms. Interest previously accrued but not collected on loans is reversed through interest income at the date a loan is placed on nonaccrual status. For single-family loans on nonaccrual status, we recognize income when cash payments are received. We return a non-modified single-family loan to accrual status at the point that the borrower brings the loan current. We return a modified single-family loan to accrual status at the point that the borrower successfully makes all required payments during the trial period (generally three to four months) and the modification is made permanent. As of January 1, 2020, we place a multifamily loan on nonaccrual status when the loan becomes two months or more past due according to its contractual terms unless the loan is well secured such that collectability of principal and accrued interest is reasonably assured. For multifamily loans on nonaccrual status, we apply any payment received on a cost recovery basis to reduce principal on the mortgage loan. We return a multifamily loan to accrual status when the borrower cures the delinquency of the loan. Transactions related to the

Our allowance for loan losses is a valuation account that is deducted from the amortized cost basis of HFI loans to present the net amount expected to be collected on the loans. The allowance for loan losses reflects an estimate of expected credit losses on single-family and multifamily HFI loans held by Fannie Mae and by consolidated Fannie Mae MBS trusts. Estimates of credit losses are based on expected cash flows derived from internal models that estimate loan performance under simulated ranges of economic environments. Our modeled loan performance is based on our historical experience of loans with similar risk characteristics adjusted to reflect current conditions and reasonable and supportable forecasts. Our historical loss experience and our credit loss estimates capture the possibility of remote events that could result in credit losses on loans that are considered low risk. The allowance for loan losses does not consider benefits from freestanding credit enhancements, such as our CAS and CIRT programs and multifamily DUS lender risk-sharing arrangements, which are recorded in “Other assets” in our condensed consolidated balance sheets. For loans that were current as of March 1, 2020 and subsequently became delinquent or entered into forbearance during the COVID-19 pandemic, see changes to our allowance for loan losses in the section on New Accounting Guidance below. For loans not subject to the COVID-19 related guidance, we have elected not to measure an allowance for credit losses on accrued interest receivable balances as we have a nonaccrual policy to ensure the timely reversal of unpaid accrued interest. See “Note 4, Allowance for Loan Losses” for additional information about our current period provision for loan losses, including a discussion of the estimates used in measuring the impact of the COVID-19 pandemic on our allowance.

Changes to our estimate of expected credit losses, including changes due to the passage of time, are recorded through the benefit (provision) for credit losses. When calculating our allowance for loan losses, we consider only our amortized cost in the loans at the balance sheet date. We record write-offs as a reduction to the allowance for loan losses when losses are confirmed through the receipt of assets in satisfaction of a loan, such as the underlying collateral upon foreclosure or cash upon completion of a short sale. Additionally, we record write-offs as a reduction to our allowance for loan losses when a loan is determined to be uncollectible and upon the transfer of a nonperforming loan from HFI to HFS. We include expected recoveries of amounts previously written off and expected to be written off in determining our allowance for loan losses.

We estimate the amount expected to be collected on our single-family loans using a discounted cash flow approach. Our allowance for loan losses is calculated as the difference between the amortized cost basis of the loan and the present value of expected cash flows on the loan. Expected cash flows include payments from the borrower, net of servicing fees, contractually attached credit enhancements and proceeds from the sale of the underlying collateral, net of selling costs.

When foreclosure of a single-family loan is probable, the allowance for loan losses is calculated as the difference between the amortized cost basis of the loan and the fair value of the collateral as of the reporting date, adjusted for the estimated costs to sell the property and the amount of expected recoveries from contractually attached credit enhancements or other proceeds we expect to receive.

Expected cash flows are developed using internal models that capture market and loan characteristic inputs. Market inputs include information such as actual and forecasted home prices, interest rates, volatility, and spreads, while loan characteristic inputs include information such as mark-to-market loan-to-value (“LTV”) ratios, delinquency status, geography, and borrower FICO credit scores. The model assigns a probability to borrower events including contractual payment, loan payoff and default under various economic environments based on historical data, current conditions, and reasonable and supportable forecasts.

The two primary drivers of our forecasted economic environments are interest rates and home prices. Our model projects the range of possible interest rate scenarios over the life of the loan based on actual interest rates and observed option pricing volatility in the capital markets. We develop regional forecasts based on Metropolitan Statistical Area data for single-family home prices using a multi-path simulation that captures home price projections over a five-year period, the period for which we can develop reasonable and supportable forecasts. After the five-year period, the home price forecast immediately reverts to a historical long-term growth rate.

Expected cash flows on the loan are discounted at the effective interest rate on the loan, adjusted for expected prepayments. For single-family loans that have not been modified in a troubled debt restructuring (“TDR”), the discount rate is updated each reporting period to reflect changes in expected prepayments. Expected cash flows do not include expected extensions of the contractual term unless such extension is the result of a reasonably expected TDR.

We consider the effects of actual and reasonably expected TDRs in our estimate of credit losses. These effects include any economic concession provided or expected to be provided to a borrower experiencing financial difficulty. We consider our current servicing practices and our historical experience to estimate reasonably expected TDRs. When a loan is contractually modified in a TDR, to capture the concession, the discount rate on the loan is locked to the rate in effect just prior to the modification and is no longer updated for changes in expected prepayments.

Our allowance for loan losses on multifamily loans is calculated based on estimated probabilities of default and loss severities to derive expected loss ratios, which are then applied to the amortized cost basis of the loans. Our probabilities of default and severity are estimated using internal models based on historical loss experience of loans with similar risk characteristics that affect credit performance, such as debt service coverage ratio (“DSCR”), mark-to-market LTV ratio, collateral type, age, loan size, geography, prepayment penalty term, and note type. Our models simulate a range of possible future economic scenarios, which are used to estimate probabilities of default and loss severities. Key inputs to our models include rental income, which drives expected DSCRs for our loans, and capitalization rates, which project future property values. Our reasonable and supportable forecasts for multifamily rental income and capitalization rates, which are projected based on Metropolitan Statistical Area data, extend through the contractual maturity of the loans. For TDRs, we use a discounted cash flow approach to estimate expected credit losses.

When foreclosure of a multifamily loan is probable, the allowance for loan losses is calculated as the difference between the amortized cost basis of the loan and the fair value of the collateral as of the reporting date, adjusted for the estimated costs to sell the property and the amount of expected recoveries from contractually attached credit enhancements or other proceeds we expect to receive.

Earnings per share (“EPS”) is presented for basic and diluted EPS. We compute basic EPS by dividing net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. However, as a result of our conservatorship status and the terms of the senior preferred stock, no amounts would be available to distribute as dividends to common or preferred stockholders (other than to Treasury as the holder of the senior preferred stock). Net income (loss) attributable to common stockholders excludes amounts attributable to the senior preferred stock. Weighted average common shares include 4.7 billion and 4.6 billion shares for the periods ended September 30, 2020 and 2019, respectively, that would be issued upon the full exercise of the warrant issued to Treasury from the date the warrant was issued through September 30, 2020 and 2019, respectively.

The calculation of diluted EPS includes all the components of basic earnings per share, plus the dilutive effect of common stock equivalents such as convertible securities and stock options. Weighted average shares outstanding is increased to include the number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued. Our diluted EPS weighted-average shares outstanding includes 26 million and 131 million shares issuable upon the conversion of convertible preferred stock as of September 30, 2020 and 2019, respectively. For the three months ended September 30, 2019, convertible preferred stock is not included in the calculation because a net loss attributable to common shareholders was incurred and it would have an anti-dilutive effect.

Section 4013 of the Coronavirus Aid, Relief, and Economic Security Act, referred to as the CARES Act, which was enacted in March 2020, provides temporary relief from the accounting and reporting requirements for TDRs regarding certain loan modifications related to COVID-19. The CARES Act provides that a financial institution may elect to suspend the TDR requirements under GAAP for loan modifications related to the COVID-19 pandemic that occur between March 1, 2020 through the earlier of December 31, 2020 or 60 days after the date on which the COVID-19 national emergency terminates (the “Applicable Period”), as long as the loan was not more than 30 days delinquent as of December 31, 2019. Loan modifications are defined in this section of the CARES Act to include forbearance arrangements, repayment plans, interest rate modifications, and any similar arrangement that defer or delay the payment of principal or interest.

We have elected to account for eligible loan modifications under Section 4013 of the CARES Act. Therefore, the initial relief (i.e., the forbearance arrangement) and the subsequent agreements (i.e., repayment plans, payment deferrals and loan modifications) that are necessary to allow the borrower to repay the past due amounts (collectively, the “COVID-19 Relief”), will not be subject to the specialized accounting or disclosures that are required for TDRs if the initial relief related to COVID-19 is granted during the Applicable Period and the borrower was no more than 30 days past due as of December 31, 2019.

In addition to the CARES Act, the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, National Credit Union Administration, Office of the Comptroller of the Currency, Consumer Financial Protection Bureau and the State Banking Regulators (collectively, the “Banking Agencies”) issued an Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (the “Interagency Statement”) in April 2020. The Interagency Statement primarily provides incremental guidance related to the nonaccrual of interest income. It indicates that financial institutions may continue to accrue interest income on loans that are granted short-term payment delays, such as forbearance, if the delay is in response to COVID-19 and the loan was less than 30 days past due at the time the delay was granted.

Pursuant to the Interagency Statement, we continue to recognize interest income at the current contractual yield for up to six months on loans that were current at March 1, 2020 and have been negatively impacted by COVID-19. For loans that are in a forbearance plan beyond six months of delinquency, we continue to accrue interest income provided collection of principal and interest continues to be reasonably assured.

Our evaluation of whether the collection of principal and interest is reasonably assured will consider the probability of default, the current value of the collateral, and any proceeds that are expected from contractually attached mortgage insurance. Once the forbearance period has ended, we will also consider the extent to which the borrower and the servicer have agreed to any of the loss mitigation options that are available. For single-family loans placed on nonaccrual status, cash payments are applied as a reduction of accrued interest receivable until the receivable has been reduced to zero, and then we recognize income on a cash basis when payments are received.

For loans that have been negatively impacted by COVID-19, we establish a valuation allowance for expected credit losses on the accrued interest receivable balance applying the process that we have established for both single-family and multifamily loans. The credit expense related to this valuation allowance is classified as a component of the provision for credit losses. This receivable is written off when the amount is deemed to be uncollectible, in accordance with our write-off policy for mortgage loans.

As a result of this update to the application of our nonaccrual policy for loans negatively impacted by COVID-19, we recognized $763 million and $2.2 billion in interest income for the three and nine months ended September 30, 2020, respectively. We also recognized $569 million of provision for loan losses on the related accrued interest receivable for the nine months ended September 30, 2020.

The Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments in June 2016, which was later amended by ASU 2019-04, ASU 2019-05 and ASU 2019-11. These ASUs (the “CECL standard”) replaced the existing incurred loss impairment methodology for loans that are collectively evaluated for impairment with a methodology that reflects lifetime expected credit losses and requires consideration of a broader range of reasonable and supportable forecast information to develop a lifetime credit loss estimate. The CECL standard also requires credit losses related to AFS debt securities to be recorded through an allowance for credit losses. Our adoption of this standard on January 1, 2020 did not have a material impact on our portfolio of AFS debt securities.

The CECL standard became effective for our fiscal year beginning January 1, 2020. We have changed our accounting policies as described above and implemented system, model and process changes to adopt the standard. Upon adoption, we used a discounted cash flow method to measure expected credit losses on our single-family mortgage loans and an undiscounted loss method to measure expected credit losses on our multifamily mortgage loans. The models used to estimate credit losses incorporated our historical credit loss experience, adjusted for current economic forecasts and the current credit profile of our loan book of business. The models used reasonable and supportable forecasts for key economic drivers, such as home prices (single-family), rental income (multifamily) and capitalization rates (multifamily).

The adoption of the CECL standard on January 1, 2020 reduced our retained earnings by $1.1 billion on an after-tax basis. The adoption of this guidance increased our overall credit loss reserves primarily as the result of an increase in our single-family loan loss reserves that were previously evaluated on a collective basis for impairment. This increase was partially offset by a decrease in estimated credit losses on loans that were previously considered individually impaired (our TDRs).

The increase in our single-family loan loss reserves that were previously evaluated on a collective basis was primarily driven by the migration from an incurred-loss approach, which allowed us to consider only default events and economic conditions that already existed as of each financial reporting date, to an estimate that incorporates both expected default events over the expected life of each mortgage loan and a forecast of home prices in different economic environments over a reasonable and supportable period. The increase in loss reserves for this portion of our book was low relative to its size due to the credit quality of these loans and because as of the date of adoption our current model forecasted home price growth.

The allowance for loan losses on the TDR book was already measured using an expected lifetime credit loss estimate. The credit losses on this portion of our single-family book decreased upon the adoption of the CECL standard because the new guidance required us to exclude from our estimate of credit losses all pre-foreclosure and post-foreclosure costs that are expected to be advanced after the balance sheet date. Prior to the adoption of the CECL standard, we incorporated these costs in our estimate of credit losses for this book.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provides optional temporary relief to ease the potential burden of transitioning away from LIBOR and other discontinued interest rates. Specifically, ASU 2020-04 provides optional practical expedients and exceptions under GAAP related to contract modifications and hedging relationships that reference LIBOR or another reference rate expected to be discontinued. Qualifying for the accounting relief provided by ASU 2020-04 is subject to meeting certain criteria and is generally only available to contract modifications made and hedging relationships entered into or evaluated prospectively from March 12, 2020 through December 31, 2022.

In May 2020, we modified trust agreements governing our Fannie Mae REMIC and other multi-class transactions issued prior to July 2013 that are backed by floating rate or reverse floating rate securities to include fallback provisions in order to ease the potential burden of transitioning away from LIBOR. The update to the fallback language in the Omnibus Trust Supplement qualified for the accounting relief provided by ASU 2020-04, and we accounted for the update as a modification to the existing agreements. The impact of the May 2020 agreement modifications governing Fannie Mae REMIC and multi-class transactions issued prior to July 2013 was not material to Fannie Mae. We had no hedge accounting relationships between March 12, 2020 and September 30, 2020. We will continue to evaluate ASU 2020-04 to determine the timing and extent to which we will apply the provided accounting relief.
