Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Fannie Mae is a leading source of financing for mortgages in the United States. We are a shareholder-owned corporation organized as a government-sponsored entity (“GSE”) and existing under the Federal National Mortgage Association Charter Act (the “Charter Act” or our “charter”). Our charter is an act of Congress, and we have a mission under that charter to provide liquidity and stability to the residential mortgage market and to promote access to mortgage credit. As a result, 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. We have been under conservatorship, with FHFA acting as conservator, since September 6, 2008. See below and “Note 1, Summary of Significant Accounting Policies” in our annual report on Form 10-K for the year ended December 31, 2020 (“2020 Form 10-K”) for additional information on our conservatorship and the impact of U.S. government support of our business. The unaudited interim condensed consolidated financial statements as of and for the three and six months ended June 30, 2021 and related notes should be read in conjunction with our audited consolidated financial statements and related notes included in our 2020 Form 10-K. Basis of Presentation 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. Results for the three and six months ended June 30, 2021 may not necessarily be indicative of the results for the year ending December 31, 2021. Presentation of Restricted Cash and Cash Equivalents Restricted cash and cash equivalents includes funds held by consolidated MBS trusts that have not yet been remitted to MBS certificateholders under the terms of our servicing guide and the related trust agreements. In 2021, Fannie Mae, in its role as trustee, began to invest funds held by consolidated trusts directly in eligible short-term third-party investments, which may include investments in cash equivalents that are comprised of overnight repurchase agreements and U.S. Treasuries that have a maturity at the date of acquisition of three months or less. The funds underlying these short-term investments are restricted per the trust agreements. Accordingly, any investment in cash equivalents should be classified as restricted and is presented as “Restricted cash and cash equivalents” in our condensed consolidated balance sheets to reflect the investment of funds related to MBS trusts. Use of Estimates 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 and 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, including the pace and strength of post-pandemic economic growth, required substantial management judgment in assessing our allowance for loan losses as of June 30, 2021. Actual results could be different from these estimates. Conservatorship 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, with FHFA acting as our conservator, 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 Housing and Economic Recovery 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. 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 continue to exist following conservatorship. Under the GSE Act, FHFA must place us into receivership if the Director of FHFA makes a written determination that our assets are less than our obligations or if we have not been paying our debts, in either case, for a period of 60 days. In addition, the Director of FHFA may place us into receivership at the Director’s discretion at any time for other reasons set forth in the GSE Act, including if we are critically undercapitalized or if we are undercapitalized and have no reasonable prospect of becoming adequately capitalized. Should we be placed into receivership, different assumptions could be required to determine the carrying value of our assets, which could lead to substantially different financial results. 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. We are not aware of any plans of FHFA (1) to fundamentally change our business model, or (2) to reduce the aggregate amount available to or held by the company under our capital structure, which includes the senior preferred stock purchase agreement. Senior Preferred Stock Purchase Agreement and Senior Preferred Stock Under our senior preferred stock purchase agreement with Treasury, in September 2008 we issued Treasury one million shares of senior preferred stock and a warrant to purchase shares of our common stock. The senior preferred stock purchase agreement and the dividend and liquidation provisions of the senior preferred stock were amended in January 2021 pursuant to a letter agreement between us, through FHFA in its capacity as conservator, and Treasury. These changes included the following: •The dividend provisions of the senior preferred stock were amended to permit us to retain increases in our net worth until our net worth exceeds the amount of adjusted total capital necessary for us to meet the capital requirements and buffers under the enterprise regulatory capital framework discussed in “Note 12, Regulatory Capital Requirements” in our 2020 Form 10-K. After the “capital reserve end date,” which is defined as the last day of the second consecutive fiscal quarter during which we have had and maintained capital equal to, or in excess of, all of the capital requirements and buffers under the enterprise regulatory capital framework, the amount of quarterly dividends to Treasury will be equal to the lesser of any quarterly increase in our net worth and a 10% annual rate on the then-current liquidation preference of the senior preferred stock. •At the end of each fiscal quarter, through and including the capital reserve end date, the liquidation preference of the senior preferred stock will be increased by an amount equal to the increase in our net worth, if any, during the immediately prior fiscal quarter. •We may issue and retain up to $70 billion in proceeds from the sale of common stock without Treasury’s prior consent, provided that (1) Treasury has already exercised its warrant in full, and (2) all currently pending significant litigation relating to the conservatorship and to an amendment to the senior preferred stock purchase agreement made in August 2012 has been resolved, which may require Treasury’s assent. •FHFA may release us from conservatorship without Treasury’s consent after (1) all currently pending significant litigation relating to the conservatorship and to the August 2012 amendment to the senior preferred stock purchase agreement has been resolved, and (2) our common equity tier 1 capital, together with any other common stock that we may issue in a public offering, equals or exceeds 3% of our “adjusted total assets” under our enterprise regulatory capital framework. •New restrictive covenants were added that impact both our single-family and multifamily business activities. The amendment has been accounted for as a modification of the existing arrangement. As a result, there is no change in the carrying value of the senior preferred stock. 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 June 30, 2021, and the amount of remaining funding available to us under the agreement is $113.9 billion. We have not received any funding from Treasury under this commitment since the first quarter of 2018. Dividend provisions of the senior preferred stock permit us to retain increases in our net worth until our net worth exceeds the amount of adjusted total capital necessary for us to meet the capital requirements and buffers under the enterprise regulatory capital framework established by FHFA in November 2020. The aggregate liquidation preference of the senior preferred stock increased to $151.7 billion as of June 30, 2021 and will further increase to $158.8 billion as of September 30, 2021 due to the $7.1 billion increase in our net worth during the second quarter of 2021. See “Note 11, Equity” in our 2020 Form 10-K for additional information about the senior preferred stock purchase agreement and the senior preferred stock. Statutory Capital We submit capital reports to FHFA, which monitors our capital levels. The deficit of core capital over statutory minimum capital was $111.5 billion as of June 30, 2021 and $124.3 billion as of December 31, 2020. Related Parties 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 June 30, 2021, Treasury held an investment in our senior preferred stock with an aggregate liquidation preference of $151.7 billion. See “Senior Preferred Stock Purchase Agreement and Senior Preferred Stock” above for additional information on transactions under this agreement and the modifications made in the January 2021 letter 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 a result, 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. 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. Some of the structured securities we issue are backed in whole or in part by Freddie Mac securities. Fannie Mae and Freddie Mac each have agreed to indemnify the other party for losses caused by: its failure to meet its payment or other specified obligations under the trust agreements pursuant to which the underlying resecuritized securities were issued; its failure to meet its obligations under the customer services agreement; its violations of laws; or with respect to material misstatements or omissions in offering documents, ongoing disclosures and related materials relating to the underlying resecuritized securities. Additionally, we make regular income tax payments to and receive tax refunds from the Internal Revenue Service (“IRS”), a bureau of Treasury. Transactions with Treasury Our administrative expenses were reduced by $5 million and $4 million for the three months ended June 30, 2021 and 2020, respectively, and $9 million for the six months ended June 30, 2021 and 2020, 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. In 2012, FHFA and Treasury advised us to remit this fee increase to Treasury with respect to all loans acquired by us on or after April 1, 2012 and before January 1, 2022, and to continue to remit these amounts to Treasury on and after January 1, 2022 with respect to loans we acquired before this date until those loans are paid off or otherwise liquidated. The resulting fee revenue and expense are recorded in “Interest income: Mortgage loans” 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 $758 million and $660 million in TCCA fees during the three months ended June 30, 2021 and 2020, respectively, and $1.5 billion and $1.3 billion for the six months ended June 30, 2021 and 2020, respectively, of which $758 million had not been remitted to Treasury as of June 30, 2021. 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, were 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 $57 million and $55 million in “Other expenses, net” for the three months ended June 30, 2021 and 2020, respectively, and $119 million and $85 million for the six months ended June 30, 2021 and 2020, respectively, in connection with Treasury’s Capital Magnet Fund, of which $119 million has not been remitted as of June 30, 2021. Transactions with FHFA 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 for the three months ended June 30, 2021 and 2020, and $72 million and $67 million for the six months ended June 30, 2021 and 2020, respectively. Transactions with CSS and Freddie Mac We contributed capital to CSS, the company we jointly own with Freddie Mac, of $18 million and $19 million for the three months ended June 30, 2021 and 2020, respectively, and $45 million and $48 million for the six months ended June 30, 2021 and 2020, respectively. Derivatives We recognize our derivatives as either assets or liabilities in our condensed consolidated balance sheets at their fair value on a trade date basis. Changes in fair value and interest accruals on derivatives not in qualifying fair value hedging relationships are recorded as “Fair value gains (losses), net” in our condensed consolidated statements of operations and comprehensive income. We offset the carrying amounts of certain derivatives that are in gain positions and loss positions as well as cash collateral receivables and payables associated with derivative positions pursuant to the terms of enforceable master netting arrangements. We offset these amounts only when we have the legal right to offset under the contract and we have met all the offsetting conditions. For our over-the-counter (“OTC”) derivative positions, our master netting arrangements allow us to net derivative assets and liabilities with the same counterparty. For our cleared derivative contracts, our master netting arrangements allow us to net our exposure by clearing organization and by clearing member. After offsetting, we report derivatives in a gain position in “Other assets” and derivatives in a loss position in “Other liabilities” in our condensed consolidated balance sheets. We evaluate financial instruments that we purchase or issue and other financial and non-financial contracts for embedded derivatives. To identify embedded derivatives that we must account for separately, we determine whether: (1) the economic characteristics of the embedded derivative are not clearly and closely related to the economic characteristics of the financial instrument or other contract (i.e., the host contract); (2) the financial instrument or other contract itself is not already measured at fair value with changes in fair value included in earnings; and (3) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative. If the embedded derivative meets all three of these conditions, we elect to carry the hybrid contract in its entirety at fair value with changes in fair value recorded in earnings. Fair Value Hedge Accounting In January 2021, to reduce earnings volatility related to changes in benchmark interest rates, we began applying fair value hedge accounting to certain pools of single-family mortgage loans and certain issuances of our funding debt by designating such instruments as the hedged item in hedging relationships with interest-rate swaps. In these relationships, we have designated the change in the benchmark interest rate, either the London Inter-bank Offered Rate (“LIBOR”) or Secured Overnight Financing Rate (“SOFR”), as the risk being hedged. We have elected to use the last-of-layer method to hedge certain pools of single-family mortgage loans. This election involves establishing fair value hedging relationships on the portion of each loan pool that is not expected to be affected by prepayments, defaults and other events that affect the timing and amount of cash flows. The term of each hedging relationship is generally one business day and we establish hedging relationships daily to align our hedge accounting with our risk management practices. We apply hedge accounting to qualifying hedging relationships. A qualifying hedging relationship exists when changes in the fair value of a derivative hedging instrument are expected to be highly effective in offsetting changes in the fair value of the hedged item attributable to the risk being hedged during the term of the hedging relationship. We assess hedge effectiveness using statistical regression analysis. A hedging relationship is considered highly effective if the total change in fair value of the hedging instrument and the change in the fair value of the hedged item due to changes in the benchmark interest rate offset each other within a range of 80% to 125% and certain other statistical tests are met. If a hedging relationship qualifies for hedge accounting, the change in the fair value of the interest-rate swaps and the change in the fair value of the hedged item for the risk being hedged are recorded through net interest income. A corresponding basis adjustment is recorded against the hedged item, either the pool of mortgage loans or the debt, for the changes in the fair value attributable to the risk being hedged. For hedging relationships that hedge pools of single-family mortgage loans, basis adjustments are allocated to individual single-family loans based on the relative unpaid principal balance of each loan at the termination of the hedging relationship. The cumulative basis adjustments on the hedged item are amortized into earnings using the effective interest method over the contractual life of the hedged item, with amortization beginning upon termination of the hedging relationship. All changes in fair value of the designated portion of the derivative hedging instrument (i.e., interest-rate swap), including interest accruals, are recorded in the same line item in the condensed consolidated statements of operations and comprehensive income used to record the earnings effect of the hedged item. Therefore, changes in the fair value of the hedged mortgage loans and debt attributable to the risk being hedged are recognized in “Interest income” or “Interest expense,” along with the changes in the fair value of the respective derivative hedging instruments. The recognition of basis adjustments on the hedged item and the subsequent amortization are noncash activities and are removed from net income to derive the “Net cash provided by (used in) operating activities” in our condensed consolidated statement of cash flows. Cash on derivative instruments paid or received while the derivative is designated in a hedging relationship is reported as “Net cash provided by (used in) operating activities” in the condensed consolidated statement of cash flows. See “Note 3, Mortgage Loans,” “Note 7, Short-Term and Long-Term Debt” and “Note 8, Derivative Instruments” for additional information on our fair value hedge accounting policy and related disclosures. Earnings per Share 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 shares for the periods ended June 30, 2021 and 2020 that would have been issued upon the full exercise of the warrant issued to Treasury from the date the warrant was issued through June 30, 2021 and 2020. 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. For the three and six months ended June 30, 2021 and the three months ended June 30, 2020, our diluted EPS weighted-average shares outstanding includes 26 million shares issuable upon the conversion of convertible preferred stock. For the six months ended June 30, 2020, 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.

Fannie Mae is a leading source of financing for mortgages in the United States. We are a shareholder-owned corporation organized as a government-sponsored entity (“GSE”) and existing under the Federal National Mortgage Association Charter Act (the “Charter Act” or our “charter”). Our charter is an act of Congress, and we have a mission under that charter to provide liquidity and stability to the residential mortgage market and to promote access to mortgage credit. As a result, 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.

We have been under conservatorship, with FHFA acting as conservator, since September 6, 2008. See below and “Note 1, Summary of Significant Accounting Policies” in our annual report on Form 10-K for the year ended December 31, 2020 (“2020 Form 10-K”) for additional information on our conservatorship and the impact of U.S. government support of our business.

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. Results for the three and six months ended June 30, 2021 may not necessarily be indicative of the results for the year ending December 31, 2021.

Restricted cash and cash equivalents includes funds held by consolidated MBS trusts that have not yet been remitted to MBS certificateholders under the terms of our servicing guide and the related trust agreements. In 2021, Fannie Mae, in its role as trustee, began to invest funds held by consolidated trusts directly in eligible short-term third-party investments, which may include investments in cash equivalents that are comprised of overnight repurchase agreements and U.S. Treasuries that have a maturity at the date of acquisition of three months or less. The funds underlying these short-term investments are restricted per the trust agreements. Accordingly, any investment in cash equivalents should be classified as restricted and is presented as “Restricted cash and cash equivalents” in our condensed consolidated balance sheets to reflect the investment of funds related to MBS trusts.

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 and 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, including the pace and strength of post-pandemic economic growth, required substantial management judgment in assessing our allowance for loan losses as of June 30, 2021. Actual results could be different 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, with FHFA acting as our conservator, 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 Housing and Economic Recovery 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.

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 continue to exist following conservatorship. Under the GSE Act, FHFA must place us into receivership if the Director of FHFA makes a written determination that our assets are less than our obligations or if we have not been paying our debts, in either case, for a period of 60 days. In addition, the Director of FHFA may place us into receivership at the Director’s discretion at any time for other reasons set forth in the GSE Act, including if we are critically undercapitalized or if we are undercapitalized and have no reasonable prospect of becoming adequately capitalized. Should we be placed into receivership, different assumptions could be required to determine the carrying value of our assets, which could lead to substantially different financial results. 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. We are not aware of any plans of FHFA (1) to fundamentally change our business model, or (2) to reduce the aggregate amount available to or held by the company under our capital structure, which includes the senior preferred stock purchase agreement.

Under our senior preferred stock purchase agreement with Treasury, in September 2008 we issued Treasury one million shares of senior preferred stock and a warrant to purchase shares of our common stock. The senior preferred stock purchase agreement and the dividend and liquidation provisions of the senior preferred stock were amended in January 2021 pursuant to a letter agreement between us, through FHFA in its capacity as conservator, and Treasury. These changes included the following:

•The dividend provisions of the senior preferred stock were amended to permit us to retain increases in our net worth until our net worth exceeds the amount of adjusted total capital necessary for us to meet the capital requirements and buffers under the enterprise regulatory capital framework discussed in “Note 12, Regulatory Capital Requirements” in our 2020 Form 10-K. After the “capital reserve end date,” which is defined as the last day of the second consecutive fiscal quarter during which we have had and maintained capital equal to, or in excess of, all of the capital requirements and buffers under the enterprise regulatory capital framework, the amount of quarterly dividends to Treasury will be equal to the lesser of any quarterly increase in our net worth and a 10% annual rate on the then-current liquidation preference of the senior preferred stock.

•We may issue and retain up to $70 billion in proceeds from the sale of common stock without Treasury’s prior consent, provided that (1) Treasury has already exercised its warrant in full, and (2) all currently pending significant litigation relating to the conservatorship and to an amendment to the senior preferred stock purchase agreement made in August 2012 has been resolved, which may require Treasury’s assent.

•FHFA may release us from conservatorship without Treasury’s consent after (1) all currently pending significant litigation relating to the conservatorship and to the August 2012 amendment to the senior preferred stock purchase agreement has been resolved, and (2) our common equity tier 1 capital, together with any other common stock that we may issue in a public offering, equals or exceeds 3% of our “adjusted total assets” under our enterprise regulatory capital framework.

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 June 30, 2021, and the amount of remaining funding available to us under the agreement is $113.9 billion. We have not received any funding from Treasury under this commitment since the first quarter of 2018.

Dividend provisions of the senior preferred stock permit us to retain increases in our net worth until our net worth exceeds the amount of adjusted total capital necessary for us to meet the capital requirements and buffers under the enterprise regulatory capital framework established by FHFA in November 2020. The aggregate liquidation preference of the senior preferred stock increased to $151.7 billion as of June 30, 2021 and will further increase to $158.8 billion as of September 30, 2021 due to the $7.1 billion increase in our net worth during the second quarter of 2021.

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 June 30, 2021, Treasury held an investment in our senior preferred stock with an aggregate liquidation preference of $151.7 billion. See “Senior Preferred Stock Purchase Agreement and Senior Preferred Stock” above for additional information on transactions under this agreement and the modifications made in the January 2021 letter 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 a result, 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.

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. Some of the structured securities we issue are backed in whole or in part by Freddie Mac securities. Fannie Mae and Freddie Mac each have agreed to indemnify the other party for losses caused by: its failure to meet its payment or other specified obligations under the trust agreements pursuant to which the underlying resecuritized securities were issued; its failure to meet its obligations under the customer services agreement; its violations of laws; or with respect to material misstatements or omissions in offering documents, ongoing disclosures and related materials relating to the underlying resecuritized 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 and $4 million for the three months ended June 30, 2021 and 2020, respectively, and $9 million for the six months ended June 30, 2021 and 2020, 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. In 2012, FHFA and Treasury advised us to remit this fee increase to Treasury with respect to all loans acquired by us on or after April 1, 2012 and before January 1, 2022, and to continue to remit these amounts to Treasury on and after January 1, 2022 with respect to loans we acquired before this date until those loans are paid off or otherwise liquidated. The resulting fee revenue and expense are recorded in “Interest income: Mortgage loans” and “TCCA fees,” respectively, in our condensed consolidated statements of operations and comprehensive income.

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, were 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 $57 million and $55 million in “Other expenses, net” for the three months ended June 30, 2021 and 2020, respectively, and $119 million and $85 million for the six months ended June 30, 2021 and 2020, respectively, in connection with Treasury’s Capital Magnet Fund, of which $119 million has not been remitted as of June 30, 2021.

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 for the three months ended June 30, 2021 and 2020, and $72 million and $67 million for the six months ended June 30, 2021 and 2020, respectively.

We recognize our derivatives as either assets or liabilities in our condensed consolidated balance sheets at their fair value on a trade date basis. Changes in fair value and interest accruals on derivatives not in qualifying fair value hedging relationships are recorded as “Fair value gains (losses), net” in our condensed consolidated statements of operations and comprehensive income. We offset the carrying amounts of certain derivatives that are in gain positions and loss positions as well as cash collateral receivables and payables associated with derivative positions pursuant to the terms of enforceable master netting arrangements. We offset these amounts only when we have the legal right to offset under the contract and we have met all the offsetting conditions. For our over-the-counter (“OTC”) derivative positions, our master netting arrangements allow us to net derivative assets and liabilities with the same counterparty. For our cleared derivative contracts, our master netting arrangements allow us to net our exposure by clearing organization and by clearing member.

We evaluate financial instruments that we purchase or issue and other financial and non-financial contracts for embedded derivatives. To identify embedded derivatives that we must account for separately, we determine whether: (1) the economic characteristics of the embedded derivative are not clearly and closely related to the economic characteristics of the financial instrument or other contract (i.e., the host contract); (2) the financial instrument or other contract itself is not already measured at fair value with changes in fair value included in earnings; and (3) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative. If the embedded derivative meets all three of these conditions, we elect to carry the hybrid contract in its entirety at fair value with changes in fair value recorded in earnings.

In January 2021, to reduce earnings volatility related to changes in benchmark interest rates, we began applying fair value hedge accounting to certain pools of single-family mortgage loans and certain issuances of our funding debt by designating such instruments as the hedged item in hedging relationships with interest-rate swaps. In these relationships, we have designated the change in the benchmark interest rate, either the London Inter-bank Offered Rate (“LIBOR”) or Secured Overnight Financing Rate (“SOFR”), as the risk being hedged. We have elected to use the last-of-layer method to hedge certain pools of single-family mortgage loans. This election involves establishing fair value hedging relationships on the portion of each loan pool that is not expected to be affected by prepayments, defaults and other events that affect the timing and amount of cash flows. The term of each hedging relationship is generally one business day and we establish hedging relationships daily to align our hedge accounting with our risk management practices.

We apply hedge accounting to qualifying hedging relationships. A qualifying hedging relationship exists when changes in the fair value of a derivative hedging instrument are expected to be highly effective in offsetting changes in the fair value of the hedged item attributable to the risk being hedged during the term of the hedging relationship. We assess hedge effectiveness using statistical regression analysis. A hedging relationship is considered highly effective if the total change in fair value of the hedging instrument and the change in the fair value of the hedged item due to changes in the benchmark interest rate offset each other within a range of 80% to 125% and certain other statistical tests are met.

If a hedging relationship qualifies for hedge accounting, the change in the fair value of the interest-rate swaps and the change in the fair value of the hedged item for the risk being hedged are recorded through net interest income. A corresponding basis adjustment is recorded against the hedged item, either the pool of mortgage loans or the debt, for the changes in the fair value attributable to the risk being hedged. For hedging relationships that hedge pools of single-family mortgage loans, basis adjustments are allocated to individual single-family loans based on the relative unpaid principal balance of each loan at the termination of the hedging relationship. The cumulative basis adjustments on the hedged item are amortized into earnings using the effective interest method over the contractual life of the hedged item, with amortization beginning upon termination of the hedging relationship.

All changes in fair value of the designated portion of the derivative hedging instrument (i.e., interest-rate swap), including interest accruals, are recorded in the same line item in the condensed consolidated statements of operations and comprehensive income used to record the earnings effect of the hedged item. Therefore, changes in the fair value of the hedged mortgage loans and debt attributable to the risk being hedged are recognized in “Interest income” or “Interest expense,” along with the changes in the fair value of the respective derivative hedging instruments.

The recognition of basis adjustments on the hedged item and the subsequent amortization are noncash activities and are removed from net income to derive the “Net cash provided by (used in) operating activities” in our condensed consolidated statement of cash flows. Cash on derivative instruments paid or received while the derivative is designated in a hedging relationship is reported as “Net cash provided by (used in) operating activities” in the condensed consolidated statement of cash flows.

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 shares for the periods ended June 30,

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. For the three and six months ended June 30, 2021 and the three months ended June 30, 2020, our diluted EPS weighted-average shares outstanding includes 26 million shares issuable upon the conversion of convertible preferred stock. For the six months ended June 30, 2020, 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.
