Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Summary of Significant Accounting Policies Freddie Mac is a GSE chartered by Congress in 1970, with a mission to provide liquidity, stability, and affordability to the U.S. housing market. We are regulated by FHFA, the SEC, HUD, and Treasury, and are currently operating under the conservatorship of FHFA. For additional information on the roles of FHFA and Treasury, see Note 2 . Throughout our consolidated financial statements and related notes, we use certain acronyms and terms which are defined in the Glossary . Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with GAAP and include our accounts as well as the accounts of other entities in which we have a controlling financial interest. All intercompany balances and transactions have been eliminated. We are operating under the basis that we will realize assets and satisfy liabilities in the normal course of business as a going concern and in accordance with the authority provided by FHFA to our Board of Directors to oversee management's conduct of our business operations. Use of Estimates The preparation of our consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Management has made significant estimates to report the allowance for credit losses on single-family mortgage loans. Actual results could be different from these estimates. Consolidation and Equity Method Accounting For each entity with which we are involved, we determine whether the entity should be consolidated in our financial statements. We consolidate entities in which we have a controlling financial interest. The method for determining whether a controlling financial interest exists varies depending on whether the entity is a VIE. For entities that are not VIEs, we hold a controlling financial interest in entities where we hold a majority of the voting rights or a majority of a limited partnership's kick-out rights through voting interests. We do not currently consolidate any entities which are not VIEs. We use the equity method to account for our interests in entities in which we do not have a controlling financial interest, but over which we have significant influence. Cash and Cash Equivalents Highly liquid investment securities that have an original maturity of three months or less are accounted for as cash equivalents. Original maturity means the original maturity to us when we acquire the investment, not the original maturity of the instrument itself. Cash collateral accepted from counterparties that we do not have the right to use for general corporate purposes is classified as restricted cash and cash equivalents on our consolidated balance sheets. Restricted cash and cash equivalents includes cash remittances received from servicers of the underlying assets of our consolidated trusts which are deposited into a separate custodial account. We invest the cash held in the custodial account in short-term investments; and we are entitled to the interest income earned on these short-term investments, which is recorded as interest income on our consolidated statements of income. Comprehensive Income Comprehensive income includes all changes in equity during a period, except those resulting from investments by, or distributions to, stockholders. Comprehensive income consists of net income plus other comprehensive income, including unrealized gains and losses on available-for-sale securities. Other Significant Accounting Policies The table below identifies our other significant accounting policies and the related note in which information about each policy can be found. Note Accounting Policy Note 3 Securitizations and Variable Interest Entities Note 4 Mortgage Loans Note 5 Guarantees and Other Off-Balance Sheet Credit Exposures Note 6 Allowance for Credit Losses Note 7 Investment Securities Note 8 Debt Note 9 Derivatives Note 10 Collateralized Agreements Note 11 Stockholders' Equity Note 11 Earnings Per Share Note 13 Income Taxes Note 14 Segment Reporting Note 16 Fair Value Disclosures Recently Adopted Accounting Guidance Standard Description Date of Adoption Effect on Consolidated Financial Statements ASU 2022-01 , Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method The amendments in this Update provide clarifications of the guidance in ASC Topic 815 on fair value hedge accounting of interest rate risk for portfolios of financial assets. The Update amends the guidance in ASU 2017-12 that, among other things, establishes the "last-of-layer" method for making the fair value hedge accounting for these portfolios more accessible by allowing the entities to apply the portfolio layer method to portfolios of all financial assets, including both prepayable and nonprepayable financial assets. The Update provides additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method. January 1, 2023 The adoption of these amendments did not have a material effect on our consolidated financial statements. We adopted the guidance in this Update related to disclosures on a prospective basis. ASU 2022-02 , Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures The amendments in this Update require disclosure of current period gross write-offs by year of origination for financing receivables within the scope of ASC Subtopic 326-20. January 1, 2023 for the amendments related to disclosure of gross write-offs by year of origination. The adoption of these amendments did not have a material effect on our consolidated financial statements. See Note 4 for additional disclosure of gross write-offs by year of origination. Recently Issued Accounting Guidance, Not Yet Adopted Within Our Consolidated Financial Statements Standard Description Date of Planned Adoption Effect on Consolidated Financial Statements ASU 2023-02 , Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method The amendments in this Update expand the use of the proportional amortization method of accounting to equity investments in other tax credit structures that meet certain conditions. This Update also amends those conditions primarily to assess projected benefits on a discounted basis and expands the disclosure requirements of those investments. January 1, 2024 We do not expect the adoption of ASU 2023-07 , Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures The amendments in this Update require the disclosure of more detailed quantitative and qualitative information about significant segment expenses that are regularly provided to the CODM and included in each reported measure of segment profit or loss. December 31, 2024 We do not expect the adoption of ASU 2023-09 , Income Taxes (Topic 740): Improvements to Income Tax Disclosures The amendments in this Update require annual disclosure of more detailed tax rate reconciliation categories and income taxes paid by geography and jurisdiction. January 1, 2025 We do not expect the adoption of

Conservatorship and Related Matters [Abstract]
CONSERVATORSHIP AND RELATED MATTERS	Conservatorship and Related Matters Business Objectives We operate under the conservatorship that commenced on September 6, 2008, conducting our business under the direction of FHFA, as our Conservator. The conservatorship and related matters significantly affect our management, business activities, financial condition, and results of operations. Upon its appointment, FHFA, as Conservator, immediately succeeded to all rights, titles, powers, and privileges of Freddie Mac, and of any stockholder, officer, or director thereof, with respect to the company and its assets. The Conservator also succeeded to the title to all books, records, and assets of Freddie Mac held by any other legal custodian or third party. The Conservator provided for the Board of Directors to perform certain functions and to oversee management, and the Board of Directors delegated to management authority to conduct business operations so that the company can continue to operate in the ordinary course. The directors serve on behalf of, and perform such functions as provided by, the Conservator. We are subject to certain constraints on our business activities under the Purchase Agreement. However, the support provided by Treasury pursuant to the Purchase Agreement currently enables us to maintain our access to the debt markets and to have adequate liquidity to conduct our normal business activities, although the costs of our debt funding could vary. Our ability to access funds from Treasury under the Purchase Agreement is critical to keeping us solvent. Our current business objectives reflect direction we have received from the Conservator (including the Conservatorship Scorecards). At the direction of the Conservator, we have made changes to certain business practices that are designed to provide support for the mortgage market in a manner that serves our mission and other non-financial objectives but may not contribute to our profitability. Certain of these objectives are intended to help homeowners and the mortgage market and may help to mitigate future credit losses. Some of these initiatives affect our near- and long-term financial results. Given our mission and the important role the Administration and our Conservator have placed on Freddie Mac in addressing housing and mortgage market conditions, we may be required to take actions that could have a negative impact on our business, operating results, or financial condition. Under the Purchase Agreement, we cannot return capital to stockholders other than Treasury, the holder of our senior preferred stock. Our future is uncertain, and the conservatorship has no specified termination date. We do not know what changes may occur to our business model during or following conservatorship, including whether we will continue to exist. Our Conservator has not made us aware of any plans to make any significant changes that would affect our ability to continue as a going concern. Our future structure and role will be determined by the Administration, Congress, and FHFA. It is possible, and perhaps likely, that there will be significant changes to our business beyond the near term. Purchase Agreement and Warrant Overview On September 7, 2008, we, through FHFA, in its capacity as Conservator, entered into the Purchase Agreement with Treasury. The Purchase Agreement was subsequently amended and restated on September 26, 2008, and further amended on May 6, 2009, December 24, 2009, August 17, 2012, December 21, 2017, September 27, 2019, January 14, 2021, and September 14, 2021. The amount of available funding remaining under the Purchase Agreement was $140.2 billion as of December 31, 2023. This amount will be reduced by any future draws. The Purchase Agreement requires Treasury, upon the request of the Conservator, to provide funds to us after any quarter in which we have a negative net worth (that is, our total liabilities exceed our total assets, as reflected on our consolidated balance sheets). In addition, the Purchase Agreement requires Treasury, upon the request of the Conservator, to provide funds to us if the Conservator determines, at any time, that it will be mandated by law to appoint a receiver for us unless we receive these funds from Treasury. In exchange for Treasury's funding commitment, we issued to Treasury, as an aggregate initial commitment fee, one million shares of Variable Liquidation Preference Senior Preferred Stock with an initial liquidation preference of $1 billion, which we refer to as the senior preferred stock, and a warrant to purchase, for a nominal price, shares of our common stock equal to 79.9% of the total number of shares of our common stock outstanding on a fully diluted basis at the time the warrant is exercised, which we refer to as the warrant. We received no cash proceeds or other consideration from Treasury for issuing the senior preferred stock or the warrant. The amount of any draw will be added to the aggregate liquidation preference of the senior preferred stock. Deficits in our net worth have made it necessary for us to make substantial draws on Treasury's funding commitment under the Purchase Agreement. Pursuant to the December 2017 Letter Agreement, the liquidation preference of the senior preferred stock increased by $3.0 billion on December 31, 2017. Pursuant to the September 2019 Letter Agreement and January 2021 Letter Agreement, increases in the Net Worth Amount, if any, during the immediately prior fiscal quarter have been, or will be, added to the liquidation preference of the senior preferred stock at the end of each fiscal quarter, from September 30, 2019 through the Capital Reserve End Date. The liquidation preference of the senior preferred stock was $117.3 billion on December 31, 2023 and will increase to $120.4 billion on March 31, 2024 based on the increase in our Net Worth Amount during 4Q 2023. Under the Purchase Agreement, our ability to repay the liquidation preference of the senior preferred stock is limited, and we will not be able to do so for the foreseeable future, if at all. In addition to increases based on quarterly increases in our Net Worth Amount, as discussed above, the liquidation preference will increase if we receive additional draws under the Purchase Agreement or if any dividends or quarterly commitment fees payable under the Purchase Agreement are not paid in cash. Treasury, as the holder of the senior preferred stock, is entitled to receive quarterly cash dividends, when, as, and if declared by our Board of Directors. The dividends we have paid to Treasury on the senior preferred stock have been declared by, and paid at the direction of, the Conservator, acting as successor to the rights, titles, powers, and privileges of the Board of Directors. Through December 31, 2012, the senior preferred stock accrued quarterly cumulative dividends at a rate of 10% per year. Under the August 2012 amendment to the Purchase Agreement, the fixed dividend rate was replaced with a net worth sweep dividend beginning in the first quarter of 2013. Accordingly, our cash dividend requirement for each quarter from January 1, 2013 until the Capital Reserve End Date is the amount, if any, by which our Net Worth Amount at the end of the immediately preceding fiscal quarter, less the applicable Capital Reserve Amount, exceeds zero. The term Net Worth Amount is defined as the total assets of Freddie Mac (excluding Treasury's commitment and any unfunded amounts thereof), less our total liabilities (excluding any obligation in respect of capital stock), in each case as reflected on our consolidated balance sheets prepared in accordance with GAAP. If the calculation of the dividend payment for a quarter does not exceed zero, then no dividend will accrue or be payable for that quarter. The applicable Capital Reserve Amount is currently the amount of adjusted total capital necessary to meet capital requirements and buffers set forth in the ERCF. This Capital Reserve Amount will remain in effect until the last day of the second consecutive fiscal quarter during which we have reached and maintained such level of capital (the Capital Reserve End Date). As a result, we will not be required to pay a dividend on the senior preferred stock to Treasury until we have built sufficient net worth to meet the capital requirements and buffers set forth in the ERCF. If for any reason we were not to pay our dividend requirement on the senior preferred stock in full in any future period until the Capital Reserve End Date, the unpaid amount would be added to the liquidation preference and the applicable Capital Reserve Amount would thereafter be zero. Based on our Net Worth Amount at December 31, 2023 and the applicable Capital Reserve Amount, we will not have a dividend requirement to Treasury in March 2024. Since the beginning of the conservatorship through December 31, 2023, we have paid cash dividends of $119.7 billion to Treasury at the direction of the Conservator. After the Capital Reserve End Date, we will be subject to a new periodic cash dividend requirement. Our quarterly senior preferred stock dividend requirement will be an amount equal to the lesser of (1) 10% per annum on the then-current liquidation preference of the senior preferred stock and (2) a quarterly amount equal to the increase in the Net Worth Amount, if any, during the immediately prior fiscal quarter. If for any reason we were not to pay our dividend requirement on the senior preferred stock in full in any future period after the Capital Reserve End Date, the unpaid amount would be added to the liquidation preference and immediately following such failure and for all dividend periods thereafter until the dividend period following the date on which we shall have paid in cash full cumulative dividends, the dividend amount will be 12% per annum on the then-current liquidation preference of the senior preferred stock. The amounts payable for dividends on the senior preferred stock could be substantial and will have an adverse impact on our financial position and net worth. The senior preferred stock is senior in liquidation preference to our common stock and all other series of preferred stock. In addition to the issuance of the senior preferred stock and warrant, we are required under the Purchase Agreement to pay a quarterly commitment fee to Treasury. Under the Purchase Agreement, the fee was to be determined in an amount mutually agreed to by us and Treasury with reference to the market value of Treasury's funding commitment as then in effect. However, pursuant to the August 2012 amendment to the Purchase Agreement, as further amended by the January 2021 Letter Agreement, for each quarter commencing January 1, 2013, no periodic commitment fee under the Purchase Agreement will be set, accrue, or be payable. Pursuant to the January 2021 Letter Agreement, by the Capital Reserve End Date, we and Treasury, in consultation with the Chairman of the Federal Reserve, will mutually agree on a periodic commitment fee that we will pay for Treasury's remaining funding commitment with respect to the five-year period commencing on the first January 1 after the Capital Reserve End Date. The Purchase Agreement includes significant restrictions on our ability to manage our business, including limits on the amount of indebtedness we can incur, the size of our mortgage-related investments portfolio, our secondary market activities, and our single-family and multifamily loan acquisitions. The Purchase Agreement has an indefinite term and can terminate only in limited circumstances, which do not include the end of the conservatorship. The Purchase Agreement therefore could continue after the conservatorship ends. However, Treasury's consent is required for a termination of conservatorship other than in connection with receivership or under the limited circumstances specified in the Purchase Agreement involving maintenance of certain capital and resolution of currently pending material litigation related to our conservatorship and the Purchase Agreement. Treasury has the right to exercise the warrant, in whole or in part, at any time on or before September 7, 2028. Purchase Agreement Covenants The Purchase Agreement provides that, until the senior preferred stock is repaid or redeemed in full, we may not, without the prior written consent of Treasury: n Declare or pay any dividend (preferred or otherwise) or make any other distribution with respect to any Freddie Mac equity securities (other than with respect to the senior preferred stock or warrant); n Redeem, purchase, retire, or otherwise acquire any Freddie Mac equity securities (other than the senior preferred stock or warrant); n Sell or issue any Freddie Mac equity securities (other than the senior preferred stock, warrant, and common stock issuable upon exercise of the warrant and certain issuance(s) of common stock after the occurrence of both Treasury's exercise in full of its warrant to acquire 79.9% of our common stock and resolution of currently pending material litigation relating to our conservatorship and the Purchase Agreement); n Terminate the conservatorship (other than in connection with a receivership or under limited circumstances involving maintenance of certain capital levels and resolution of currently pending material litigation related to our conservatorship and the Purchase Agreement); n Sell, transfer, lease, or otherwise dispose of any assets, other than dispositions for fair market value: l To a limited life regulated entity (in the context of a receivership); l Of assets and properties in the ordinary course of business, consistent with past practice; l Of assets and properties having fair market value individually or in aggregate less than $250 million in one transaction or a series of related transactions; l In connection with our liquidation by a receiver; l Of cash or cash equivalents for cash or cash equivalents; or l To the extent necessary to comply with the covenant described below relating to the reduction of our mortgage-related investments portfolio. n Issue any subordinated debt; n Enter into a corporate reorganization, recapitalization, merger, acquisition, or similar event; or n Engage in transactions with affiliates unless the transaction is: l Pursuant to the Purchase Agreement, the senior preferred stock, or the warrant; l Upon arm's length terms; or l A transaction undertaken in the ordinary course or pursuant to a contractual obligation or customary employment arrangement in existence on the date of the Purchase Agreement. In addition, the Purchase Agreement requires us to comply with the ERCF as published in December 2020, disregarding any subsequent amendment or other modification to that rule. Consistent with FHFA instruction, we are reporting our regulatory capital requirements under the ERCF as subsequently amended by FHFA. Therefore, we are not in compliance with this Purchase Agreement covenant. FHFA has acknowledged this noncompliance. For additional information on the ERCF, see Note 18 . The Purchase Agreement limits the size of our mortgage-related investments portfolio to a maximum amount of $225 billion effective December 31, 2022. The calculation of mortgage assets subject to the Purchase Agreement cap includes the UPB of mortgage assets and 10% of the notional value of interest-only securities. Our mortgage-related investments portfolio for purposes of the FHFA and Purchase Agreement caps was $107.2 billion at December 31, 2023, including $22.2 billion representing 10% of the notional amount of the interest-only securities we held as of December 31, 2023. Our ability to acquire and sell mortgage assets continues to be significantly constrained by limitations imposed by the Purchase Agreement and FHFA. With respect to the composition of our mortgage-related investments portfolio, FHFA has instructed us to (1) hold no more than $20 billion in Single-Family agency MBS with all dollar caps to be based on UPB and (2) hold no CMOs, which are also sometimes referred to as REMICs. We will have a holding period limit to sell any new CMO tranches created but not sold at issuance. CMOs do not include tranches initially retained from reperforming loans senior subordinate securitizations. Under the Purchase Agreement, we also may not, without the prior written consent of Treasury, incur indebtedness that would result in the par value of our aggregate indebtedness exceeding 120% of the amount of mortgage assets we are permitted to own on December 31 of the immediately preceding calendar year. Our debt cap under the Purchase Agreement was $270 billion on January 1, 2023 as a result of the decrease in the mortgage assets limit under the Purchase Agreement to $225 billion on December 31, 2022. The mortgage asset and indebtedness limitations are determined without giving effect to the changes to the accounting guidance for transfers of financial assets and consolidation of VIEs, under which we consolidated certain VIEs in our consolidated financial statements as of January 1, 2010. As of December 31, 2023, our aggregate indebtedness for purposes of the debt cap was $174.0 billion. Our aggregate indebtedness calculation primarily includes the par value of short- and long-term debt. In addition, the Purchase Agreement provides that we may not enter into any new compensation arrangements or increase amounts or benefits payable under existing compensation arrangements of any named executive officer or other executive officer (as such terms are defined by SEC rules) without the consent of the Director of FHFA, in consultation with the Secretary of the Treasury. The Purchase Agreement also provides that, on an annual basis, we are required to deliver a risk management plan to Treasury setting out our strategy for reducing our enterprise-wide risk profile and the actions we will take to reduce the financial and operational risk associated with each of our reportable business segments. The Purchase Agreement also restricts our secondary market activities and single-family and multifamily loan acquisitions: n Secondary Market Activities - We cannot vary the pricing or any other term of the acquisition of a single-family loan based on the size, charter type, or volume of business of the seller of the loan and are required to: l Offer to purchase loans for cash consideration and operate this cash window with non-discriminatory pricing; l Beginning on January 1, 2022, limit the volume purchased through the cash window to $1.5 billion per lender during any period comprising four calendar quarters; and l Comply with directives, regulations, restrictions, or other requirements prescribed by FHFA related to equitable secondary market access by community lenders. n Multifamily New Business Activity - We are required to cap multifamily loan purchases at $80 billion in any 52-week period, subject to annual adjustment by FHFA based on changes in the Consumer Price Index. At least 50% of our multifamily loan purchases in any calendar year must be, at the time of acquisition, classified as mission-driven pursuant to FHFA guidelines. n Single-Family Loan Acquisitions - We are required to limit our acquisition of certain single-family mortgage loans. l A maximum of 6% of purchase money mortgages and 3% of refinance mortgages over the preceding 52-week period can have two or more of the following characteristics at origination: combined LTV ratio greater than 90%; DTI ratio greater than 45%; and FICO or equivalent credit score less than 680. l We are required to limit acquisitions of single-family mortgage loans secured by either second homes or investment properties to 7% of the single-family mortgage loan acquisitions over the preceding 52-week period. l Subject to such exceptions as FHFA may prescribe to permit us to acquire single-family mortgage loans that are currently eligible for acquisition, we are required to implement a program reasonably designed to ensure that each single-family mortgage is: – A qualified mortgage; – Expressly exempt from the CFPB’s ability-to-repay requirements; – If secured by an investment property, subject to the related Purchase Agreement restriction described below, which has been suspended; – A refinancing with streamlined underwriting for high LTV ratios; – A loan with temporary underwriting flexibilities due to exigent circumstances, as determined in consultation with FHFA; or – Secured by manufactured housing. In September 2021, the Purchase Agreement requirements related to the $1.5 billion limit on our cash window volumes and requirements related to our multifamily loan purchase activity, acquisitions of single-family loans with certain LTV, DTI, and credit score characteristics at origination, and acquisitions of single-family loans secured by second homes or investment properties were suspended. Each such suspension shall terminate six months after Treasury notifies us that such suspension has been terminated. Warrant Covenants The warrant we issued to Treasury includes, among others, the following covenants: n Our SEC filings under the Exchange Act will comply in all material respects as to form with the Exchange Act and the rules and regulations thereunder; n Without the prior written consent of Treasury, we may not permit any of our significant subsidiaries to issue capital stock or equity securities, or securities convertible into or exchangeable for such securities, or any stock appreciation rights or other profit participation rights to any person other than Freddie Mac or its wholly-owned subsidiaries; n We may not take any action that will result in an increase in the par value of our common stock; n Unless waived or consented to in writing by Treasury, we may not take any action to avoid the observance or performance of the terms of the warrant and we must take all actions necessary or appropriate to protect Treasury's rights against impairment or dilution; and n We must provide Treasury with prior notice of specified actions relating to our common stock, such as setting a record date for a dividend payment, granting subscription or purchase rights, authorizing a recapitalization, reclassification, merger or similar transaction, commencing a liquidation of the company, or any other action that would trigger an adjustment in the exercise price or number or amount of shares subject to the warrant. Termination Provisions The Purchase Agreement provides that the Treasury's funding commitment will terminate under any of the following circumstances: n The completion of our liquidation and fulfillment of Treasury's obligations under its funding commitment at that time; n The payment in full of, or reasonable provision for, all of our liabilities (whether or not contingent, including mortgage guarantee obligations); and n The funding by Treasury of the maximum amount of the commitment under the Purchase Agreement. In addition, Treasury may terminate its funding commitment and declare the Purchase Agreement null and void if a court vacates, modifies, amends, conditions, enjoins, stays, or otherwise affects the appointment of the Conservator or otherwise curtails the Conservator's powers. Treasury may not terminate its funding commitment under the Purchase Agreement solely by reason of our being in conservatorship, receivership or other insolvency proceeding, or due to our financial condition or any adverse change in our financial condition. Waivers and Amendments The Purchase Agreement provides that most provisions of the agreement may be waived or amended by mutual written agreement of the parties; however, no waiver or amendment of the agreement is permitted that would decrease Treasury's aggregate funding commitment or add conditions to Treasury's funding commitment if the waiver or amendment would adversely affect in any material respect the holders of our debt securities or mortgage guarantee obligations. Third-Party Enforcement Rights In the event of our default on payments with respect to our debt securities or mortgage guarantee obligations, if Treasury fails to perform its obligations under its funding commitment and if we and/or the Conservator are not diligently pursuing remedies in respect of that failure, the holders of these debt securities or mortgage guarantee obligations may file a claim in the United States Court of Federal Claims for relief requiring Treasury to fund to us the lesser of: n The amount necessary to cure the payment defaults on our debt securities and mortgage guarantee obligations and n The lesser of: l The deficiency amount and l The maximum amount of the commitment less the aggregate amount of funding previously provided under the commitment. Any payment that Treasury makes under those circumstances will be treated for all purposes as a draw under the Purchase Agreement that will increase the liquidation preference of the senior preferred stock. See Note 11 for additional information on the conservatorship and the Purchase Agreement. Related Parties as a Result of Conservatorship As a result of our issuance to Treasury of the warrant to purchase shares of our common stock equal to 79.9% of the total number of shares of our common stock outstanding, on a fully diluted basis, we are deemed a related party to the U.S. government. During the years ended December 31, 2023, 2022, and 2021, no transactions outside of normal business activities have occurred between us and the U.S. government (or any of its related parties), except for the following: n The transactions with Treasury discussed above in Purchase Agreement and Warrant ; n The transactions entered into whereby we and Fannie Mae, in conjunction with Treasury, provided assistance to state and local HFAs. Treasury will reimburse Freddie Mac for initial guarantee losses on these transactions; n The allocation or transfer of 4.2 bps of each dollar of new business purchases to certain housing funds as required under the GSE Act. During the years ended December 31, 2023, 2022, and 2021, we recognized $0.1 billion, $0.3 billion, and $0.5 billion, respectively, of expense related to the affordable housing funds. These amounts are included in legislative assessments expense on our consolidated statements of income; and n The legislated guarantee fees on single-family loans that are remitted to Treasury as required by law. During the years ended December 31, 2023, 2022, and 2021, we recognized $2.9 billion, $2.8 billion, and $2.3 billion, respectively, of expense related to the legislated guarantee fees. These amounts are included in legislative assessments expense on our consolidated statements of income. In addition, we are deemed a related party with Fannie Mae as both we and Fannie Mae have the same relationships with FHFA and Treasury. All transactions between us and Fannie Mae have occurred in the normal course of business in conservatorship other than our relationship with CSS discussed below. In October 2013, FHFA announced the formation of CSS. CSS is a limited liability company equally-owned by Freddie Mac and Fannie Mae, and CSS is also deemed a related party. In connection with the formation of CSS, we entered into a limited liability company (LLC) agreement with Fannie Mae. Additionally, we and Fannie Mae each appointed two executives to the CSS Board of Managers and signed governance and operating agreements for CSS, including an updated customer services agreement with Fannie Mae and CSS in May 2019. In June 2019, we entered into an agreement with Fannie Mae regarding the commingling of certain of our mortgage securities and related indemnification obligations. During the year ended December 31, 2023, we contributed $72 million of capital to CSS, and we have contributed $871 million since the fourth quarter of 2014. The carrying value of our investment in CSS was ($1) million and ($2) million as of December 31, 2023 and December 31, 2022. respectively. In January 2020, FHFA directed Freddie Mac and Fannie Mae to amend the LLC agreement for CSS to change the structure of the Board of Managers (CSS Board). The revised LLC agreement also removed the requirement that any CSS Board decision must be approved by at least one of the CSS Board members appointed by Freddie Mac and one appointed by Fannie Mae. These amendments reduce Freddie Mac’s and Fannie Mae’s ability to control CSS Board decisions, even after conservatorship, including decisions about strategy, business operations, and funding.

Securitizations and Variable In

Securitizations and Variable Interest Entities	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
SECURITIZATION ACTIVITIES AND CONSOLIDATION	Securitizations and Variable Interest Entities Our primary business activities in the Single-Family and Multifamily segments involve the securitization of loans or other mortgage-related assets using trusts that are VIEs. These trusts issue beneficial interests in the loans or other mortgage-related assets that they own. We guarantee the principal and interest payments on some or all of the issued beneficial interests in substantially all of our securitization transactions. We also use trusts that are VIEs in certain CRT products. Consolidated VIEs We consolidate VIEs when we have a controlling financial interest in the VIE and are therefore considered the primary beneficiary of the VIE. We are the primary beneficiary of a VIE when we have both the power to direct the activities of the VIE that most significantly impact its economic performance and exposure to losses or benefits of the VIE that could potentially be significant to the VIE. We evaluate whether we are the primary beneficiary of VIEs in which we have interests at both inception and on an ongoing basis, and the primary beneficiary determination may change over time as our interest in the VIE changes. Generally, the assets of our consolidated VIEs can be used only to settle obligations of the VIE, and the creditors of our consolidated VIEs have recourse to the general credit of Freddie Mac only to the extent that we have provided a guarantee to the VIE. When we consolidate a VIE, we recognize the assets and liabilities of the VIE on our consolidated balance sheets and account for those assets and liabilities based on the applicable GAAP for each specific type of asset or liability. Assets and liabilities that we transfer to a VIE at, after, or shortly before the date we become the primary beneficiary of the VIE are initially measured at the same amounts that they would have been measured if they had not been transferred, and no gain or loss is recognized on these transfers. For all other VIEs that we consolidate, we recognize the assets and liabilities of the VIE at fair value, and we recognize a gain or loss for the difference between: n The sum of the fair value of the consideration paid, the fair value of any noncontrolling interests, and the reported amount of any previously held interests and n The fair value of the net identifiable assets recognized. Single-Family Securitization Products Level 1 Securitization Products Level 1 Securitization Products consist of UMBS, 55-day MBS, ARM and Gold PCs, which are all pass-through debt securities that represent undivided beneficial interests in a pool of loans held by a securitization trust. All Level 1 Securitization Products are backed only by mortgage loans we have acquired. We serve as both administrator and guarantor for these trusts. As administrator, we have the right to establish servicing terms and direct loss mitigation activities for the loans held by these trusts. As guarantor, we guarantee the payment of principal and interest on these securities in exchange for a guarantee fee, and we have the right to purchase delinquent loans from the trust to help improve the economic performance of the trust. We absorb all credit losses of these trusts through our guarantee of the principal and interest payments. The economic performance of these trusts is most significantly affected by the performance of the underlying loans. Our rights as administrator and guarantor provide us with the power to direct the activities that most significantly affect the performance of the underlying loans. We also have the obligation to absorb losses of these trusts that could potentially be significant through our guarantee of principal and interest payments. Accordingly, we concluded that we are the primary beneficiary of and, therefore, consolidate these trusts. Loans held by these trusts are recognized on our consolidated balance sheets as mortgage loans held-for-investment. The corresponding securities held by third parties are recognized on our consolidated balance sheets as debt. We extinguish the outstanding debt of the related consolidated trust and recognize gains or losses on debt extinguishment for the difference between the consideration paid and the debt carrying value when we purchase these securities as investments in our mortgage-related investments portfolio. Sales of these securities that were previously held as investments in our mortgage-related investments portfolio are accounted for as debt issuances. We were the primary beneficiary of, and therefore consolidated, Level 1 securitization trusts with assets totaling $3.0 trillion and $2.9 trillion at December 31, 2023 and December 31, 2022, respectively. Our exposure for guarantees to consolidated securitization trusts is generally equal to the UPB of the loans recorded on our consolidated balance sheets. Other Securitization Products We are the primary beneficiary of and, therefore, consolidate the trusts used to issue certain of our Single-Family other securitization products when we have the ability to direct the activities that most significantly affect the economic performance of the trusts and we have the obligation to absorb credit losses through our guarantee of some or all of the issued securities. As a result, we consolidated trusts used to issue these products with underlying assets totaling $4.5 billion and $5.0 billion at December 31, 2023 and December 31, 2022, respectively. Multifamily Securitization Products Multifamily PCs Multifamily PCs are fully guaranteed pass-through securities with a 55-day payment delay that are collateralized by a single underlying mortgage loan held by a securitization trust. We serve as both administrator and guarantor for these trusts. As administrator, we have the right to establish servicing terms and direct loss mitigation activities for the loans held by these trusts. As guarantor, we guarantee the payment of principal and interest on these securities in exchange for a guarantee fee, and we have the right to purchase a delinquent loan from the trust. We absorb all credit losses of these trusts through our guarantee of the principal and interest payments. The economic performance of these trusts is most significantly affected by the performance of the underlying loans. Our rights as administrator and guarantor provide us with the power to direct the activities that most significantly affect the performance of the underlying loans. We also have the obligation to absorb losses of these trusts that could potentially be significant through our guarantee of principal and interest payments. Accordingly, we concluded that we are the primary beneficiary of and, therefore, consolidate these trusts. We consolidated VIEs used in these securitizations with underlying assets totaling $44.1 billion and $29.3 billion at December 31, 2023 and December 31, 2022, respectively. K Certificates and Other Securitization Products We are the primary beneficiary of and, therefore, consolidate the trusts used to issue fully-guaranteed K Certificates and certain of our Multifamily other securitization products when we have the ability to direct the activities that most significantly affect the economic performance of the VIEs and we have the obligation to absorb credit losses through our guarantee of the issued securities. We consolidated VIEs used in these securitizations with underlying assets totaling $3.2 billion and $1.1 billion at December 31, 2023 and December 31, 2022, respectively. WI K-Deal Certificates In a WI K-Deal Certificate transaction, we forward sell a K Certificate that will be issued in the future to a WI K-Deal trust at a fixed price, thereby reducing our exposure to future changes in interest rates and K Certificate spreads. The WI K-Deal trust simultaneously issues guaranteed securities (WI Certificates). The economic performance of our WI K-Deal trusts is most significantly affected by the performance of the underlying assets. We manage the underlying assets of the trust prior to the delivery of the K Certificate and determine which K Certificate will be delivered into the trust. Therefore, we have the power to direct the activities that are most significant to the WI K-Deal trust. We also initially have economic exposure to the variability of the trust through our guarantee of the issued WI Certificates. As a result, we are the primary beneficiary of and, therefore, initially consolidate the trusts used to issue WI Certificates. Upon delivering the K Certificate into the trust, we no longer have a variable interest and therefore deconsolidate the WI K-Deal trust. During 2023 and 2022, we issued $4.9 billion and $14.7 billion, respectively, of WI Certificates, and initially consolidated the trusts. Nonconsolidated VIEs Single-Family Securitization Products We do not consolidate certain of our Single-Family other securitization products, including senior subordinate securitizations backed by seasoned loans, because we do not have the ability to direct the loss mitigation activities of the underlying loans, which is the most significant activity affecting the economic performance of the VIE. When we sell loans in this type of transaction, we derecognize the transferred loans and account for our guarantee to the nonconsolidated VIE. We account for our investments in the beneficial interests issued by the nonconsolidated VIE, if any, as investments in debt securities. We also do not consolidate the trusts used to issue certain other types of our Single-Family other securitization products when we do not have the ability to direct the activities that most significantly affect the economic performance of the VIE. Resecuritization Products We create resecuritization products primarily by using Level 1 Securitization Products, our previously issued resecuritization products, or similar TBA-eligible products issued and guaranteed by Fannie Mae as the underlying collateral. In a typical resecuritization transaction, previously issued Level 1 Securitization Products or resecuritization products are transferred to a resecuritization trust that issues beneficial interests in the underlying collateral. We establish parameters that define eligibility standards for assets that may be used as collateral for each of our resecuritization programs. Resecuritization products can then be created based on the parameters that we have established. Similar to our Level 1 Securitization Products, we guarantee the full payment of principal and interest to the investors in our resecuritization products. The main types of resecuritization products we create are single-class resecuritization products (Supers, Giant MBS, and Giant PCs) and multiclass resecuritization products (REMICs and Strips). n Single-class resecuritization products - These securities are direct pass-throughs of the cash flows of the underlying collateral, which may be previously issued Level 1 Securitization Products, single-class resecuritization products, or similar TBA-eligible products issued and guaranteed by Fannie Mae. We do not consolidate the trusts used in these transactions unless we have the unilateral ability to liquidate the trust (for example if we own all of the trust's issued beneficial interests), as these transactions do not result in any new or incremental risk to the holders of the securities issued by the resecuritization trust and because we are not exposed to any incremental rights to receive benefits or obligations to absorb losses that could be significant to the resecuritization trust. We account for purchases of single-class resecuritization products that we issue that are substantially the same as the underlying collateral as debt extinguishment of a pro-rata portion of the underlying Level 1 Securitization Product. We account for purchases of single-class resecuritization products that we issue that are not considered substantially the same as the underlying collateral as investments in debt securities. Single-class resecuritization products that we issue that are backed entirely by Freddie Mac collateral are considered substantially the same as the underlying collateral, while commingled single-class resecuritization products that we issue are not considered substantially the same as the underlying collateral. n Multiclass resecuritization products - These securities are multiclass resecuritizations of the cash flows of the underlying collateral, which may be previously issued Level 1 Securitization Products, single-class resecuritization products, multiclass resecuritization products, or similar TBA-eligible products issued and guaranteed by Fannie Mae. The activity that most significantly impacts the economic performance of our multiclass resecuritization trusts is typically the initial design and structuring of the trust. Substantially all multiclass resecuritization trusts are created as part of transactions in which an investor or dealer participates in the decisions made during the design and establishment of the trust. As a result, we do not have the unilateral ability to direct the activities of our multiclass resecuritization trusts that most significantly impact the economic performance of those trusts. In addition, unless we retain a portion of the issued multiclass resecuritization products, we do not have the right to receive benefits or the obligation to absorb losses that could potentially be significant to the trusts because we have already provided a guarantee on the underlying assets. As a result, we have concluded that we are not the primary beneficiary of our multiclass resecuritization trusts and, therefore, do not consolidate those trusts unless we have the unilateral ability to liquidate the trust. When we purchase a multiclass resecuritization product as an investment in our mortgage-related investments portfolio, we record the security as an investment in debt securities rather than extinguishment of debt since we are investing in the debt securities of a nonconsolidated entity. Similarly, sales of multiclass resecuritization products previously held as investments in our mortgage-related investments portfolio are accounted for as sales of investments in debt securities. See Note 7 for additional information on accounting for investments in debt securities. With the exception of commingled securities, our investments in, and guarantees of, securities issued by resecuritization trusts do not create any incremental exposure to loss because we already guarantee the underlying collateral. As a result, we do not receive any incremental guarantee fees in exchange for our guarantee, and, accordingly, we do not recognize any additional guarantee assets, guarantee obligations, or reserves for guarantee losses related to resecuritization trusts. In a typical multiclass resecuritization, we receive a one-time transaction fee which represents compensation for both the structuring and creation of the securities and for our ongoing administrative responsibilities to service the securities. We recognize the portion of the transaction fee related to creation of the securities immediately in earnings. We defer the portion of the fee related to ongoing administrative responsibilities and amortize it over the life of the associated trust. When we issue commingled resecuritization products, our guarantee of the Fannie Mae securities used as collateral creates incremental exposure to loss because our guarantee covers timely payment of principal and interest on such products from underlying Fannie Mae securities. If Fannie Mae were to fail to make a payment on a Fannie Mae security that we resecuritized, we would be responsible for making the payment. However, we view the likelihood of being required to perform on our guarantee of Fannie Mae securities as remote due to Fannie Mae’s status as a GSE and the funding commitment available to it through its senior preferred stock purchase agreement with Treasury. We did not charge an incremental fee for commingled securities issued prior to July 1, 2022; however, effective July 1, 2022, we began to charge a fee for any commingled security issued after that date. CRT Products We transfer credit risk exposure on certain mortgage loans that we own or guarantee using CRT products, including STACR Trust notes. In STACR Trust notes transactions, a trust issues credit-linked notes whose repayments are based on the credit performance of a reference pool of mortgage loans. The trust uses the proceeds from the issuance of the notes to purchase short-term eligible investments and makes periodic payments of principal and interest on the notes to investors. We make payments to the trust to support payment of the interest due on the notes, and we receive payments from the trust that otherwise would have been made to the noteholders to the extent there are credit events on the mortgages in the reference pool. The note balances are reduced by the amount of the payments to us. The trust was designed to create and pass along to its interest holders the variability related to the credit risk of the mortgages in the reference pool. We do not have a variable interest in the risk that the trust was designed to create and pass along to its interest holders or the power to direct the activities that most significantly affect the economic performance of the VIE. As a result, we do not consolidate the trusts used in the STACR Trust note transactions. We account for our obligations to make certain payments to the STACR Trust note VIEs to support payment of the interest due on the notes as derivative instruments. We account for our rights to receive payments from the STACR Trust note VIEs to the extent there are credit events on the mortgages in the reference pool as freestanding credit enhancement contracts. Freestanding contracts are entered into separately and apart from any other financial instrument or in conjunction with some other transaction and are legally detachable and separately exercisable. We recognize the payments we make to transfer credit risk under freestanding credit enhancements, which primarily consist of STACR Trust notes and ACIS transactions in Single-Family, in credit enhancement expense in our consolidated statements of income when they are incurred. We recognize expected recoveries from such transactions in other assets with an offsetting reduction to non-interest expense, at the same time that we recognize an allowance for credit losses on the covered loans, measured on the same basis as the allowance for credit losses on the covered loans. Credit enhancements that are not freestanding contracts are considered when measuring our allowance for credit losses. See Note 6 for additional information on credit enhancements that are not freestanding contracts. Multifamily Securitization Products K Certificates In a typical K Certificate transaction, we sell multifamily loans to a non-Freddie Mac trust that issues senior and subordinate securities, and simultaneously purchase and place the senior securities into a Freddie Mac trust that issues guaranteed K Certificates. In these transactions, we guarantee the senior securities issued by the non-Freddie Mac trust but do not issue or guarantee the subordinate securities. We receive a guarantee fee in exchange for our guarantee. In certain of our K Certificate securitizations, we may also serve as master servicer. However, in contrast to most single-family transactions, the rights to direct loss mitigation activities of the underlying loans and to purchase delinquent loans from the securitization trust are generally held by the investor in the most subordinate remaining securities issued by the non-Freddie Mac trust, and therefore we do not have the power to direct those activities unless we are the investor in the most subordinate remaining securities. We do not typically invest in the subordinate securities issued in our K Certificate transactions. The economic performance of our K Certificate trusts is most significantly affected by the performance of the underlying loans. We do not consolidate our K Certificate securitization trusts that have subordination because we do not have the ability to direct the loss mitigation activities of the underlying loans, which is the most significant activity affecting the economic performance of the VIE. When we sell loans in a K Certificate transaction, we derecognize the transferred loans and account for our guarantee to the nonconsolidated VIE. We account for our investments in the beneficial interests issued by the trusts used in our K Certificate transactions as investments in debt securities. Other Securitization Products We do not consolidate the trusts used to issue our other securitization products when we do not have the ability to direct the activities that most significantly affect the economic performance of the VIE. For those products, we account for our guarantee to the nonconsolidated VIE. We account for our investments in the beneficial interests issued by the trusts used in our other securitization products as investments in debt securities. CRT Products In Multifamily, we may transfer credit risk on certain mortgage loans that we own or guarantee by entering into SCR Trust note transactions, which are similar to STACR Trust note transactions in Single-Family. We do not consolidate the trusts used in SCR Trust note transactions and account for SCR Trust note transactions in the same manner as we account for STACR Trust note transactions. Assets and Liabilities of Nonconsolidated VIEs The following table presents the carrying amounts and classification of the assets and liabilities recorded on our consolidated balance sheets that relate to our variable interests in VIEs for which we are not the primary beneficiary and with which we were involved in the design and creation and have a significant continuing involvement, our maximum exposure to loss as a result of our involvement with such VIEs, and the total assets of the VIEs. Our involvement with such VIEs primarily consists of guarantees that we have issued to the VIE, some of which are accounted for as derivative instruments, and investments in debt securities issued by the VIE. See Note 5 for additional information on our guarantees to nonconsolidated VIEs. Total assets shown in the table below represents the remaining UPB of the mortgage loans or other noncash financial assets held by the VIE and excludes cash and nonfinancial assets held by the VIE. Maximum exposure to loss shown in the table below is primarily based on the remaining UPB of the guaranteed securities issued by the VIE and represents the contractual amounts that could be lost if the assets of the VIE (including the assets in the related reference pool for CRT products) became worthless at the balance sheet date, without consideration of proceeds from related collateral liquidation and possible recoveries under credit enhancements. We do not believe the maximum exposure to loss from our involvement with nonconsolidated VIEs is representative of the actual loss we are likely to incur based on our historical loss experience and after consideration of proceeds from related collateral liquidation and available credit enhancements.

(2) Total assets and maximum exposure to loss are based on the UPB of Fannie Mae securities underlying commingled Freddie Mac resecuritization trusts. We exclude noncommingled resecuritization trusts from these amounts as we have already guaranteed the underlying collateral and therefore noncommingled resecuritizations do not involve any incremental assets or create any incremental exposure to credit risk. Total assets exclude $0.1 billion as of both December 31, 2023 and December 31, 2022, of Fannie Mae securities that we have guaranteed that are included in resecuritization trusts that we have consolidated as we own all of the outstanding securities issued by the VIE. (3) Maximum exposure to loss is based on our expected recovery receivables and excludes our obligations to make certain payments to the VIE to support payment of the interest due on the notes issued by the VIE, which we account for as derivative instruments. The notional value of these derivative instruments is equal to the total assets of the VIE. (4) Includes total assets of $0.3 billion and $0.4 billion as of December 31, 2023 and December 31, 2022, respectively, related to VIEs in which our interest would no longer absorb significant variability as the guaranteed securities have completely paid off.

(2) Includes $1.8 billion and $1.2 billion of multifamily held-for-investment loans for which we have elected the fair value option as of December 31, 2023 and December 31, 2022, respectively. We own both single-family loans, which are secured by one- to four-unit residential properties, and multifamily loans, which are secured by properties with five or more residential rental units. Our single-family loans are predominantly first lien, fixed-rate loans secured by the borrower's primary residence. We do not typically acquire loans that have experienced more-than-insignificant deterioration in credit quality since origination as of our acquisition date, although we may acquire such loans in connection with certain of our securitization activities or other mortgage-related guarantees. Upon acquisition, we classify a loan as either held-for-investment or held-for-sale. Loans that we have the ability and intent to hold for the foreseeable future, including loans held by consolidated trusts and loans we intend to securitize using an entity we will consolidate, are classified as held-for-investment. Loans that we intend to sell are classified as held-for-sale. Held-for-investment loans for which we have not elected the fair value option are reported on our consolidated balance sheets at their amortized cost basis, net of the allowance for credit losses. The amortized cost basis is based on a loan's outstanding UPB, net of deferred fees and other cost basis adjustments (including unamortized premiums and discounts, fees we receive or pay when we acquire loans, commitment-related derivative basis adjustments, hedge accounting-related basis adjustments, and other pricing adjustments), excluding accrued interest receivable. Accrued interest receivable for both held-for-investment and held-for-sale loans is separately presented on our consolidated balance sheets and excluded for the purposes of disclosure of the amortized cost basis of mortgage loans held-for-investment. Held-for-sale loans for which we have not elected the fair value option are reported at lower-of-cost-or-fair-value determined on an individual loan basis on our consolidated balance sheets. Any excess of a held-for-sale loan's cost over its fair value is recognized as a valuation allowance in investment gains, net on our consolidated statements of income, with subsequent changes in this valuation allowance also being recorded in investment gains, net. Premiums, discounts, and other cost basis adjustments (including lower-of-cost-or-fair-value adjustments) are deferred and not amortized. We elect the fair value option for certain multifamily loans. Loans for which we have elected the fair value option are measured at fair value on a recurring basis, with subsequent gains or losses related to changes in fair value reported in investment gains, net on our consolidated statements of income. All fees, upfront costs, and other cost basis adjustments are recognized in earnings as incurred. Cash flows related to loans originally classified as held-for-investment are classified as either investing activities (e.g., principal repayments) or operating activities (e.g., interest payments received from borrowers included within net income) on our consolidated statements of cash flows. Cash flows related to loans originally classified as held-for-sale are classified as operating activities on our consolidated statements of cash flows. The table below provides details of the UPB of loans we purchased and sold during the periods presented. Table 4.2 - Loans Purchased and Sold Year Ended December 31, (In millions) 2023 2022 2021 Single-Family: Purchases: Held-for-investment loans $299,886 $540,472 $1,215,276 Sales of held-for-sale loans (1) 1,253 2,211 5,514 Multifamily: Purchases: Held-for-investment loans 16,814 25,052 9,363 Held-for-sale loans 29,415 44,997 59,093 Sales of held-for-sale loans (2) 34,034 50,280 70,355 (1) Our sales of single-family loans reflect the sale of single-family seasoned loans. (2) Our sales of multifamily loans occur primarily through the issuance of Multifamily K Certificates. Reclassifications We reclassify loans from held-for-investment to held-for-sale depending on our intent and ability to hold the loan for the foreseeable future. Upon reclassification from held-for-investment to held-for-sale, we perform a collectability assessment. When we determine that a loan to be reclassified has experienced more-than-insignificant deterioration in credit quality since origination, the excess of the loan’s amortized cost basis over its fair value is written off against the allowance for credit losses prior to the reclassification. If the charge-off amount exceeds the existing allowance for credit losses amount, an additional provision for credit losses is recognized. Any remaining allowance for credit losses after the charge-off is reversed through provision for credit losses. We reclassify loans from held-for-sale to held-for-investment when we have both the intent and ability to hold the loan for the foreseeable future. Upon reclassification from held-for-sale to held-for-investment, we reverse the loan’s held-for-sale valuation allowance, if any, and establish an allowance for credit losses as needed. The table below presents the allowance for credit losses or valuation allowance that was reversed or established due to loan reclassifications between held-for-investment and held-for-sale during the periods presented.

(2) Allowance for credit losses established upon loan reclassifications from held-for-sale to held-for-investment to reflect the net amount we expect to collect on the loan. Loans with prior charge-offs may have a negative allowance for credit losses established upon reclassification. Interest Income We recognize interest income on an accrual basis except when we believe the collection of principal and interest in full is not reasonably assured, which generally occurs when a loan is three monthly payments or more past due, at which point we place the loan on non-accrual status unless the loan is well secured and in the process of collection based upon an individual loan assessment. A loan is considered past due if a full payment of principal and interest is not received within one month of its due date. We charge off outstanding accrued interest receivable through interest income when loans are placed on non-accrual status and recognize interest income on a cash basis while a loan is on non-accrual status. Cost basis adjustments on held-for-investment loans are amortized into interest income over the contractual life of the loan using the effective interest method. No amortization is recognized during periods in which a loan is on non-accrual status. A non-accrual loan is returned to accrual status when the collectability of principal and interest in full is reasonably assured. For single-family loans, we generally determine that collectability is reasonably assured when the loan returns to current payment status. For multifamily loans, the collectability of principal and interest is considered reasonably assured based on an analysis of the factors specific to the loan being assessed. Upon a loan's return to accrual status, all previously reversed interest income is recognized and amortization of any basis adjustments into interest income is resumed. The table below presents the amortized cost basis of non-accrual loans as of the beginning and the end of the periods presented, including the interest income recognized for the period that is related to the loans on non-accrual status as of the period end.

As current LTV ratios increase, the borrower's equity in the home decreases, which may negatively affect the borrower's ability to refinance (outside of our relief refinance programs) or to sell the property for an amount at or above the balance of the outstanding loan. The tables below present the amortized cost basis of single-family held-for-investment loans by current LTV ratio.

Multifamily The table below presents the amortized cost basis of our multifamily held-for-investment loans, for which we have not elected the fair value option, by credit quality indicator, based on available data through the end of each period presented. These indicators involve significant management judgment and are defined as follows: n "Pass" is current and adequately protected by the borrower's current financial strength and debt service capacity; n "Special mention" has administrative issues that may affect future repayment prospects but does not have current credit weaknesses. In addition, this category generally includes loans in forbearance; n "Substandard" has a weakness that jeopardizes the timely full repayment; and n "Doubtful" has a weakness that makes collection or liquidation in full highly questionable and improbable based on existing conditions.

We report single-family loans in forbearance as past due during the forbearance period to the extent that payments are past due based on the loan's original contractual terms, irrespective of the forbearance plan, based on the information reported to us by our servicers. We report multifamily loans in forbearance as current as long as the borrower is in compliance with the forbearance agreement, including the agreed upon repayment plan, even if payments are past due based on the loan's original contractual terms.

(2) Loans with no allowance for loan losses primarily represent loans that were previously charged off and for which the amount we expect to collect is sufficiently in excess of the amortized cost to result in recovery of the entire amortized cost basis if the property were foreclosed upon or otherwise subject to disposition. We exclude the amounts of allowance for credit losses on accrued interest receivable and advances of pre-foreclosure costs when determining whether a loan has an allowance for credit losses. At the instruction of FHFA, we purchase single-family loans from trusts when they reach 24 months of delinquency, except for loans that meet certain criteria (e.g., permanently modified or foreclosure referral), which may be purchased sooner. Many delinquent single-family loans are purchased from trusts before they reach 24 months of delinquency under one of the exceptions provided. We must obtain FHFA’s approval to implement changes to our policy to purchase loans from trusts. Loan Restructurings In 1Q 2022, we adopted accounting guidance in ASU 2022-02 that eliminates the recognition and measurement of TDRs. Upon adoption of this guidance, we no longer measure an allowance for credit losses for TDRs we reasonably expect will occur, and we evaluate all loan restructurings according to the accounting guidance for loan refinancing and restructuring to determine whether the restructuring should be accounted for as a new loan or a continuation of the existing loan. We derecognize the existing loan and account for the restructured loan as a new loan if the effective yield on the restructured loan is at least equal to the effective yield for comparable loans with similar collection risks and the modifications to the original loan are more than minor. If a loan restructuring does not meet these conditions, we carryforward the existing loan’s amortized cost basis and account for the restructured loan as a continuation of the existing loan. Substantially all of our loan restructurings involving borrowers experiencing financial difficulty are accounted for as a continuation of the existing loan. The discounted cash flow model we use in measuring our Single-Family allowance for credit losses forecasts cash flows we expect to collect using our historical experience, including the effects of our loss mitigation activities involving borrowers experiencing financial difficulty. When we account for a loan restructuring as a continuation of the existing loan, we update the loan’s effective interest rate based on the restructured terms and recognize interest income prospectively using the new effective rate. We also update the prepayment-adjusted effective interest rate used to discount cash flows in measuring our allowance for credit losses to reflect the loan’s restructured terms. As a result, subsequent to our adoption of the accounting guidance that eliminates the recognition and measurement of TDRs, we no longer recognize an allowance for credit losses for the economic concession granted to a borrower for changes in the timing and amount of contractual cash flows when a loan is restructured. However, because we adopted such guidance prospectively, we continue to use the loan's prepayment-adjusted effective interest rate just prior to the restructuring, with no adjustments made to the effective interest rate for changes in the timing of expected cash flows subsequent to the restructuring, for loans that were restructured and accounted for as TDRs prior to our adoption of the guidance and that have not been subsequently modified after our adoption of the guidance. As a result, we continue to measure an allowance for credit losses for the economic concession granted to a borrower for changes in the timing and amount of contractual cash flows for such loans. Single-Family Loan Restructurings We offer several types of restructurings to single-family borrowers that may result in a payment delay, interest rate reduction, term extension, or combination thereof. We do not offer principal forgiveness. We offer the following types of restructurings to single-family borrowers that result in only a payment delay: n Forbearance plans - Arrangements that require reduced or no payments during a defined period that provides borrowers additional time to return to compliance with the original mortgage terms or to implement another type of loan workout option. Borrowers may exit forbearance by repaying all past due amounts thus fully reinstating the loan, paying off the loan in full, or entering into a repayment plan, a payment deferral plan, or a trial period plan pursuant to a loan modification. We offer forbearance of up to 12 months to single-family borrowers experiencing financial difficulty. Borrowers may receive an initial forbearance term of one to six months and, if necessary, one or more forbearance term extensions of one to six months, as long as the delinquency of the mortgage does not exceed 12 months. n Repayment plans - Contractual plans that allow borrowers a specific period of time to return to current status by paying the normal monthly payment plus additional agreed upon delinquent amounts. Repayment plans must have a term greater than one month and less than or equal to 12 months and the monthly repayment plan payment amount must not exceed 150% of the contractual mortgage payment amount. n Payment deferral plans - Arrangements that allow borrowers to return to current status by deferring delinquent principal and interest into a non-interest-bearing principal balance that is due at the earlier of the payoff date, maturity date, or sale of the property. The remaining mortgage term, interest rate, payment schedule, and maturity date remain unchanged, and no trial period plan is required. The number of months of payments deferred varies based upon the type of hardship the borrower is experiencing. In addition, we also offer single-family borrowers loan modifications, which are contractual plans that may involve changing the terms of the loan such as payment delays, interest rate reductions, term extensions, or a combination of these items. Payment delays in our loan modification programs most commonly consist of adding outstanding indebtedness, such as delinquent interest, to the UPB of the loan, and may also include principal forbearance, in which a portion of the principal balance becomes non-interest-bearing and is due at the earlier of the payoff date, maturity date, or sale of the property. Our modification programs generally require completion of a trial period of at least three months prior to receiving the modification. During the loan modification trial period, borrowers make payments that are an estimate of the anticipated modified payment amount, which is generally lower than the amount required by the loan's original contractual terms. As a result, loans in these modifications are granted a delay in the payment due under the original contractual terms during the trial period. We continue to report single-family loans in loan modification trial period plans as delinquent to the extent that payments are past due based on the loan’s original contractual terms. The amortized cost basis of loans in trial period modification plans was $1.7 billion and $1.3 billion as of December 31, 2023 and December 31, 2022, respectively. Most of these loans are 20- and 30-year or more, amortizing fixed-rate loans. Most of our modifications involve a combination of: (1) a payment delay in the form of adding outstanding indebtedness to the UPB of the loan and (2) an interest rate reduction, a term extension, or both. For purposes of the disclosure related to single-family loan restructurings involving borrowers experiencing financial difficulty, we exclude loans that were held-for-sale either at the time of restructuring or at the period end. The table below presents the amortized cost basis of single-family held-for-investment loan restructurings involving borrowers experiencing financial difficulty that we entered into during the periods presented.

Guarantees [Abstract]
GUARANTEES AND OTHER OFF-BALANCE SHEET CREDIT EXPOSURES	Guarantees and Other Off-Balance Sheet Credit Exposures Our guarantee activities primarily consist of mortgage-related guarantees in which we agree to absorb the credit risk of mortgage loans or other mortgage-related assets. In exchange for providing this guarantee, we receive an upfront or ongoing guarantee fee that is designed to be commensurate with the risks assumed and that will, over the long-term, provide us with cash flows that are expected to exceed the credit-related and administrative expenses of the underlying financial instruments. The profitability of our guarantee activities may vary and will depend on a number of factors, including our guarantee fee and the actual credit performance of the underlying financial instruments that we have guaranteed. We do not separately recognize guarantees to consolidated VIEs as we have already recognized the assets and liabilities of those VIEs on our consolidated balance sheets. When we issue a guarantee to a nonconsolidated VIE or other third party that exposes us to incremental credit risk, we recognize both a guarantee obligation at fair value and the consideration we receive for providing the guarantee, which typically consists of a guarantee asset that represents the fair value of future guarantee fees. As a practical expedient, the measurement of the fair value of the guarantee obligation is set equal to the consideration we receive to provide the guarantee, and no gain or loss is recognized upon issuance of the guarantee. Subsequently, we recognize changes in the fair value of the guarantee asset in current period earnings and amortize the guarantee obligation into earnings as we are released from risk under the guarantee. We also recognize an allowance for expected credit losses over the contractual period in which we are exposed to credit risk. See Note 6 for additional information on our allowance for credit losses on financial guarantees and other off-balance sheet credit exposures. Guarantee Activities Mortgage-Related Guarantees Nonconsolidated Securitization Products The majority of our mortgage-related guarantees involve securitizations of multifamily mortgage loans where we do not consolidate the securitization trust. In these transactions, we guarantee the principal and interest payments on the senior classes of beneficial interests issued by the securitization trust(s). Our maximum exposure on these guarantees is generally limited to the UPB of the beneficial interests that we have guaranteed. We have credit protection in the form of subordination that will absorb losses prior to us having to absorb losses under our guarantee, thereby reducing our expected credit losses related to such guarantees. See Note 3 for additional information on nonconsolidated VIEs. Other Mortgage-Related Guarantees In certain circumstances, we provide a credit guarantee of mortgage-related assets held by third parties, in exchange for a guarantee fee, without securitizing those assets. These guarantees consist of the following: n Long-term standby commitments of single-family loans which obligate us to purchase the covered loans when they become seriously delinquent. Periodically, certain of our customers seek to terminate long-term standby commitments and simultaneously enter into guarantor swap transactions to obtain our securities backed by many of the same loans. n Guarantees of the timely payment of principal and interest for certain multifamily bonds, which primarily consist of multifamily housing revenue bonds that were issued by HFAs. Our maximum exposure on these guarantees is limited to the UPB of the mortgage-related assets that we have guaranteed. Guarantees of Fannie Mae Securities We have the ability to commingle TBA-eligible Fannie Mae collateral in certain of our resecuritization products. We extend our guarantee of these products to cover principal and interest that are payable from the underlying Fannie Mae collateral. Because both Freddie Mac and Fannie Mae are under the common control of FHFA, and due to Fannie Mae’s status as a GSE and the funding commitment available to it through its senior preferred stock purchase agreement with Treasury, we view the likelihood of being required to perform on our guarantee of Fannie Mae collateral as remote. See Note 3 for additional information on guarantees of Fannie Mae securities. The table below presents information about our mortgage-related guarantees and guarantees of Fannie Mae securities, including the UPB of the loans or securities underlying the guarantee, the maximum potential amount of future payments that we could be required to make under the guarantee, the liability we have recognized on our consolidated balance sheets for the guarantee, and the maximum remaining term of the guarantee. This table does not include our unrecognized guarantees, such as guarantees to consolidated VIEs or to resecuritization trusts that do not expose us to incremental credit risk. We do not believe the potential amount of future payments we could be required to make is representative of the actual payments we will be required to make or the actual loss we are likely to incur, based on our historical loss experience and after consideration of proceeds from related collateral liquidation, including possible recoveries under credit enhancements.

See Note 6 for additional information on our allowance for credit losses on off-balance sheet credit exposures. (2) Maximum exposure is based on remaining UPB of the guaranteed securities issued by the VIE. (3) Includes UPB of $0.3 billion and $0.4 billion as of December 31, 2023 and December 31, 2022, respectively, related to VIEs in which our interest would no longer absorb significant variability as the guaranteed securities have completely paid off. In addition, includes guarantees that are accounted for as derivatives with UPB of $2.1 billion as of both December 31, 2023 and December 31, 2022. (4) Excludes $0.1 billion as of both December 31, 2023 and December 31, 2022, of Fannie Mae securities that we have guaranteed that are included in resecuritization trusts that we have consolidated as we own all of the outstanding securities issued by the VIE. The table below presents the payment status of the mortgage loans underlying our mortgage-related guarantees.

These transactions include our obligation to make certain payments to VIEs to support payment of the interest due on the notes issued by those VIEs in certain CRT transactions, certain interest-rate guarantees related to our securitization and resecuritization products, certain market value guarantees, and guarantees of third-party derivative instruments. These transactions generally provide for no limitation on the maximum potential future payments under the guarantee, and we generally reduce our exposure to such guarantees through separate derivative contracts with third parties. The approximate remaining term of these guarantees varies and in many cases is based on the maturity of the underlying mortgage loans. See Note 9 for additional information on derivative instruments. Indemnifications In connection with certain business transactions, we may provide indemnification to counterparties for claims arising out of breaches of certain obligations (e.g., those arising from representations and warranties) in contracts entered into in the normal course of business. Our assessment is that the risk of any material loss from such a claim for indemnification is remote and there are no significant probable and estimable losses associated with these contracts. In addition, we provided indemnification for litigation defense costs to certain former officers who are subject to ongoing litigation. See Note 17 for information on ongoing litigation. The recognized liabilities on our consolidated balance sheets related to indemnifications were not significant at both December 31, 2023 and December 31, 2022. Other Off-Balance Sheet Credit Exposures In addition to our guarantees, we enter into other agreements that expose us to off-balance sheet credit risk. These agreements may require us to transfer cash before or upon settlement of our contractual obligation. We recognize an allowance for credit losses for those agreements not measured at fair value or otherwise recognized in the financial statements. Most of these commitments expire in less than one year. See Note 6 for additional discussion of our allowance for credit losses on our off-balance sheet credit exposures. The table below presents our other off-balance sheet credit exposures.

Credit Loss [Abstract]
Allowance for Credit Losses	Allowance for Credit Losses For financial assets measured at amortized cost, we recognize an allowance for credit losses that is deducted from or added to the amortized cost basis of the financial asset to present the net amount expected to be collected on the financial asset on the balance sheet. In 1Q 2022, we adopted accounting guidance that eliminates the recognition and measurement of TDRs. Upon adoption of this guidance, we no longer incorporate the expected credit losses for TDRs we reasonably expect will occur in our estimation of the allowance for credit losses. See Note 4 for additional information on the adoption of the new accounting guidance. The table below summarizes changes in our allowance for credit losses. Table 6.1 - Details of the Allowance for Credit Losses December 31, 2023 December 31, 2022 December 31, 2021 (In millions) Single-Family Multifamily Total Single-Family Multifamily Total Single-Family Multifamily Total Beginning balance $7,746 $147 $7,893 $5,440 $78 $5,518 $6,353 $200 $6,553 Provision (benefit) for credit losses (1,172) 300 (872) 1,772 69 1,841 (919) (122) (1,041) Charge-offs (643) — (643) (505) — (505) (1,107) — (1,107) Recoveries collected 144 — 144 148 — 148 197 — 197 Other (1) 327 — 327 891 — 891 916 — 916 Ending balance $6,402 $447 $6,849 $7,746 $147 $7,893 $5,440 $78 $5,518 Components of the ending balance of the allowance for credit losses: Mortgage loans held-for-investment $6,057 $326 $6,383 $7,314 $77 $7,391 $4,913 $34 $4,947 Other (2) 345 121 466 432 70 502 527 44 571 Total ending balance $6,402 $447 $6,849 $7,746 $147 $7,893 $5,440 $78 $5,518 (1) Primarily includes capitalization of past due interest related to non-accrual loans that received payment deferral plans and loan modifications. (2) Primarily includes allowance for credit losses related to advances of pre-foreclosure costs and off-balance sheet credit exposures. n 2023 vs. 2022 - The benefit for credit losses for 2023 was primarily driven by a credit reserve release in Single-Family due to improvements in house prices. The provision for credit losses for 2022 was primarily driven by a credit reserve build in Single-Family due to deterioration in house prices. n 2022 vs. 2021 - A provision for credit losses for 2022 compared to a benefit for credit losses for 2021 primarily driven by a credit reserve build in Single-Family due to deterioration in house prices. In addition, charge-offs increased in 2023 compared to 2022 due to a higher volume of transfers of single-family loans from held-for-investment to held-for-sale and the lower fair value of these loans as a result of higher mortgage interest rates. Charge-offs decreased in 2022 compared to 2021 due to a decrease in charge-offs of accrued interest receivable during 2022. Allowance for Credit Losses Methodology We recognize changes in the allowance for credit losses through provision or benefit for credit losses on our consolidated statements of income. Mortgage Loans Held-for-Investment Our allowance for credit losses on mortgage loans pertains to single-family and multifamily loans classified as held-for-investment for which we have not elected the fair value option. We measure the allowance for credit losses on a pooled basis when our loans share similar risk characteristics. We record charge-offs in the period in which a loan is deemed uncollectible. Proceeds received in excess of amounts previously written off are recorded as a decrease to non-interest expense on our consolidated statements of income. Single-Family We estimate the allowance for credit losses for single-family loans on a pooled basis using a discounted cash flow model that evaluates a variety of factors to estimate the cash flows we expect to collect. If we determine that foreclosure on the underlying collateral is probable, we measure the allowance for credit losses for single-family loans based upon the fair value of the collateral, less costs to sell, adjusted for estimated proceeds from credit enhancements that are not freestanding contracts. The discounted cash flow model we use to estimate the single-family loan allowance for credit losses forecasts cash flows over the loan’s remaining contractual term, adjusted for expectations of prepayments. As a result, we do not revert to historical loss information for single-family loans. Cash flow estimates are discounted at the loan’s prepayment-adjusted effective interest rate, which is adjusted for projections in the underlying benchmark interest rate for adjustable-rate loans. We project cash flows we expect to collect using our historical experience, such as historical default rates and severity of loss, based on loan characteristics, such as current LTV ratios, delinquency status, geography, and borrowers' credit scores. These cash flow estimates are adjusted for current and forecasted economic conditions, such as current and forecasted interest rates and house price growth rates, and estimated recoveries from loss mitigation activities, credit enhancements that are not freestanding contracts, and disposition of collateral, less estimated disposition costs. Our estimate of expected credit losses is sensitive to changes in forecasted house price growth rates, which affect both the probability of default and severity of expected credit losses, and changes in forecasted interest rates, as declining (increasing) interest rates typically result in higher (lower) expected prepayments and a shorter (longer) estimated loan life, and therefore lower (higher) expected credit losses. Our forecast of house price growth rates leverages an internally based model and uses a nationwide house price growth forecast for the next three years. A Monte Carlo simulation generates many possible house price scenarios for up to 40 years for each MSA. These scenarios are used to estimate loan-level expected future cash flows and credit losses based on each loan’s individual characteristics. Our forecast of interest rates incorporates various interest rate scenarios over the remaining contractual life of the loan based on current interest rates and implied market volatilities. These projections require significant management judgment. We rely on third parties to provide certain model inputs used in our projections. At loan delivery, the seller provides us with loan data, which includes borrower and loan characteristics and underwriting information. Each subsequent month, the servicers provide us with monthly loan-level servicing data, including delinquency and loss information. We review the outputs of our model by considering qualitative factors such as current economic events and other external factors to determine whether the model outputs are consistent with our expectations. Further management adjustments may be necessary to take into consideration the qualitative factors that have occurred but that are not yet reflected in the factors used to derive the model outputs or the uncertainty inherent in our projections. Significant judgment is exercised in making these adjustments. Credit enhancements that are not freestanding contracts are obtained contemporaneously with, and in contemplation of, the origination of a financial instrument, and effectively travel with the financial instrument upon sale. Credit enhancements that are not freestanding contracts include primary mortgage insurance, which provides us with loan-level protection up to a specified percentage. Expected recoveries from credit enhancements that are not freestanding contracts are considered in determining the allowance for loan losses as discussed above, resulting in a reduction in the recognized provision for credit losses by the amount of the expected recoveries. Subsequent to foreclosure and charge-off of the allowance for credit losses, we reclassify expected recoveries from credit enhancements that were not freestanding contracts and were previously offset against the allowance for credit losses as separate receivables. We do not consider potential recoveries from freestanding credit enhancement contracts when measuring our allowance for credit losses. Multifamily We estimate the allowance for credit losses for multifamily loans using a loss-rate method to estimate the net amount of cash flows we expect to collect. The loss-rate method is based on a probability of default and loss given default framework that estimates credit losses by considering a loan’s underlying characteristics and current and forecasted economic conditions. Loan characteristics considered by our model include vintage, loan term, current DSCR, current LTV ratio, occupancy rate, and interest rate hedges. We generally forecast economic conditions over a reasonable and supportable two-year period prior to reverting to historical averages at the model input level over a five-year period, using a linear reversion method. We also consider as model inputs expected prepayments, contractually specified extensions, expected recoveries from collateral posting requirements, and the expected recoveries from credit enhancements that are not freestanding contracts. Our loss rates incorporate published historical commercial loan performance data, which we calibrate for differences between that data and our portfolio experience. Except for cases of fraud and certain other types of borrower defaults, most multifamily loans are nonrecourse to the borrower. As a result, the cash flows of the underlying property (including any credit enhancements that are not freestanding contracts) serve as the primary source of funds for repayment of the loan. For loans where we determined that the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the operation or sale of the collateral, we measure the allowance for credit losses using the fair value of the underlying collateral, less estimated costs to sell, adjusted for estimated proceeds from credit enhancements that are not freestanding contracts. Factors considered by management in determining whether a borrower is experiencing financial difficulty include the borrower’s current payment status and an evaluation of the underlying property's operating performance as represented by its current DSCR, its available credit enhancements, the current LTV ratio, the management of the underlying property, and the property's geographic location. We review the outputs of our model considering qualitative factors such as current economic events and other external factors to determine whether the model outputs are consistent with our expectations. Further management adjustments may be necessary to take into consideration the qualitative factors that have occurred but that are not yet reflected in the factors used to derive the model outputs. Advances of Pre-foreclosure Costs We may incur expenses related to a mortgage loan subsequent to its original acquisition but prior to foreclosure (pre-foreclosure costs). These expenses are incurred generally to protect or preserve our interest or legal right in or to the property prior to foreclosure, such as property taxes or homeowner's insurance premiums owed by the borrower. Many of these expenses are advanced by the servicer and are reimbursable from the borrower. If the borrower ultimately defaults, we reimburse the servicer for the advances it has made. Upon advance by the servicer, we recognize a receivable for the amounts due from the borrower and a payable for amounts due to the servicer. We recognize an allowance for credit losses for amounts that we do not ultimately expect to collect from the borrower. Off-Balance Sheet Credit Exposures We recognize an allowance for credit losses on off-balance sheet credit exposures for our guarantees that are not measured at fair value and other off-balance sheet arrangements based on expected credit losses over the contractual period in which we are exposed to credit risk through a present contractual obligation to extend credit, unless that obligation is unconditionally cancellable by us. We include this allowance for credit losses on off-balance sheet credit exposures within other liabilities on our consolidated balance sheets, with changes recognized through provision or benefit for credit losses on our consolidated statements of income. Our methodologies for estimating the allowance for credit losses on off-balance sheet credit exposures for our Single-Family and Multifamily guarantees are generally consistent with our methodologies for estimating the allowance for credit losses for single-family mortgage loans and multifamily mortgage loans, respectively. We obtain credit enhancements for certain of our guarantees through the creation of unguaranteed subordinated securities issued by nonconsolidated securitization trusts that absorb first losses prior to us having to perform on our guarantee of the senior securities. We consider the effect of subordination and other credit enhancements that are not freestanding contracts when measuring the allowance for credit losses on off-balance sheet credit exposures and, as a result, recognize such an allowance only if expected credit losses exceed the remaining amount of subordination. For many of our guarantees, expected credit losses do not exceed the remaining amount of subordination. We have not recorded an allowance for credit losses on our guarantees of Fannie Mae securities due to the support provided to Fannie Mae by the U.S. government, the importance of Fannie Mae to the liquidity and stability of the U.S. housing market, and the long history of zero credit losses on Fannie Mae securities.

INVESTMENT SECURITIES	Investment Securities The table below summarizes the fair values of our investments in debt securities by classification. Table 7.1 - Investment Securities (In millions) December 31, 2023 December 31, 2022 Trading securities $38,385 $32,167 Available-for-sale securities 4,890 6,534 Total fair value of investment securities $43,275 $38,701 We currently classify and account for our securities as either available-for-sale or trading. Securities classified as trading are reported at fair value with changes in fair value included in investment gains, net, in our consolidated statements of income. Securities classified as available-for-sale are reported at fair value with changes in fair value included in AOCI, net of taxes. See Note 16 for additional information on how we determine the fair value of securities. We generally record purchases and sales of non-mortgage-related securities on the trade date. We generally record purchases and sales of mortgage-related securities on the expected settlement date, with a corresponding derivative recorded on the trade date. We generally recognize interest income using the effective interest method, which considers the contractual terms of the security. Deferred items, including premiums, discounts, and other basis adjustments, are amortized into interest income over the contractual lives of the securities. We recognize interest income using the prospective effective interest method for securities that can contractually be prepaid or otherwise settled in such a way that we may not recover substantially all of our recorded investment. Under this method, we recognize as interest income, over the expected life of the securities, the excess of the cash flows expected to be collected over the securities' carrying value. We update our estimates of expected cash flows periodically and recognize changes in the calculated effective interest rate on a prospective basis. We classify the cash flows related to both available-for-sale and trading securities as investing activities because we hold these securities for investment purposes. In cases where the transfer of a security represents a secured borrowing, we classify the related cash flows as financing activities. Trading Securities The table below presents the fair values of our trading securities by major security type. Our non-mortgage-related securities primarily consist of investments in U.S. Treasury securities.

During the years ended December 31, 2023, December 31, 2022, and December 31, 2021, we derecognized $4.8 billion, $13.3 billion, and $1.1 billion respectively, of mortgage-related securities and debt of consolidated trusts where we were no longer deemed the primary beneficiary. During the year ended December 31, 2023, we purchased $4.3 billion and sold $4.4 billion of non-mortgage-related securities that were traded, but not settled at December 31, 2023. We settled our purchase and sale obligations during the first quarter of 2024.

DEBT	Debt The table below summarizes the balances of total debt on our consolidated balance sheets. Table 8.1 - Total Debt December 31, (In millions) 2023 2022 Debt of consolidated trusts $3,041,927 $2,979,070 Debt of Freddie Mac: Short-term debt 5,976 7,712 Long-term debt 160,443 159,050 Total debt of Freddie Mac 166,419 166,762 Total debt $3,208,346 $3,145,832 Debt securities that we issue are classified as either debt of consolidated trusts held by third parties or debt of Freddie Mac. We issue debt of Freddie Mac to fund our operations. Our debt is reported at amortized cost, with the exception of certain debt for which we elected the fair value option. Deferred items, including premiums, discounts, issuance costs, and hedge accounting-related basis adjustments, are reported as a component of total debt. These items are amortized and reported through interest expense using the effective interest method over the contractual life of the related indebtedness. Amortization of premiums, discounts, and issuance costs begins at the time of debt issuance. Amortization of hedge accounting-related basis adjustments begins upon the discontinuation of the related hedge relationship. We elected the fair value option on debt that contains embedded derivatives and certain other debt issuances. Changes in the fair value of these debt obligations are recorded in investment gains, net, with any upfront costs and fees incurred or received in exchange for the issuance of the debt being recognized in earnings as incurred and not deferred. Related interest expense continues to be reported as interest expense based on the stated terms of the debt securities. For additional information on our election of the fair value option, see Note 16 . When we repurchase or call outstanding debt securities, we recognize the difference between the amount paid to redeem the debt security and the carrying value in earnings as a component of investment gains, net. Contemporaneous transfers of cash between us and a creditor in connection with the issuance of a new debt security and satisfaction of an existing debt security are accounted for as either an extinguishment or a modification of an existing debt security. If the debt securities have substantially different terms, the transaction is accounted for as an extinguishment of the existing debt security. The issuance of a new debt security is recorded at fair value, fees paid to the creditor are expensed as incurred, and fees paid to third parties are deferred and amortized into interest expense over the life of the new debt security using the effective interest method. If the terms of the existing debt security and the new debt security are not substantially different, the transaction is accounted for as a modification of the existing debt. Fees paid to the creditor are deferred and amortized into interest expense over the life of the modified debt security using the effective interest method and fees paid to third parties are expensed as incurred. We also engage in transactions whereby we enter into an agreement to sell and subsequently repurchase (or purchase and subsequently resell) agency securities. When these transactions involve securities issued by consolidated entities, they are treated as issuances and extinguishments of debt. The Purchase Agreement limits the par value of our aggregate indebtedness, which may restrict the amount of debt we are allowed to issue to fund our operations. See Note 2 for information regarding restrictions on the amount of our indebtedness under the Purchase Agreement. Debt of Consolidated Trusts Debt of consolidated trusts held by third parties represent our liability to third parties that hold beneficial interests in our consolidated trusts. Debt of consolidated trusts held by third parties are subject to prepayment risk as their payments are based upon the performance of the underlying mortgage loans that may be prepaid by the related mortgage borrower at any time generally without penalty. The table below summarizes the debt of consolidated trusts based on underlying loan product type.

(2) The effective interest rate for debt of consolidated trusts was 2.73% and 2.39% as of December 31, 2023 and December 31, 2022, respectively. Short-Term Debt Discount notes, Reference Bills securities, and medium-term notes are unsecured general corporate obligations. Discount notes and Reference Bills securities pay only principal at maturity. Securities sold under agreements to repurchase are effectively collateralized borrowings where we sell securities with an agreement to repurchase such securities at a future date. We offset payables related to securities sold under agreements to repurchase against receivables related to securities purchased under agreements to resell on our consolidated balance sheets, when such amounts meet the conditions for offsetting in the accounting guidance. See Note 10 for additional information on securities sold under agreements to repurchase. Certain medium-term notes that have original maturities of one year or less are classified as short-term debt for purposes of this presentation. The table below summarizes the balances and effective interest rates for short-term debt.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	Derivatives We analyze the interest-rate sensitivity of financial assets and liabilities across a variety of interest-rate scenarios based on market prices, models, and economics. We use derivatives primarily to hedge interest-rate sensitivity mismatches between our financial assets and liabilities. We designate certain derivatives as hedging instruments in qualifying hedge accounting relationships. Interest-rate risk management derivatives that are not designated in qualifying hedge accounting relationships are economic hedges of financial instruments measured at fair value on a recurring basis or of other transactions or instruments that expose us to interest-rate risk. When we use derivatives to mitigate our exposures, we consider a number of factors, including cost, exposure to counterparty credit risk, and our overall risk management strategy. We principally use interest-rate swaps, purchased or written options (including swaptions), and exchange-traded futures in our interest-rate risk management activities. We routinely enter into commitments to purchase and sell investments in mortgage-related securities, purchase and sell mortgage loans, and purchase and extinguish or issue debt of our consolidated trusts. Most of these commitments meet the definition of a derivative and, therefore, are subject to the accounting guidance for derivatives and hedging. We also enter into certain types of guarantees that are accounted for as derivatives. These guarantees primarily include our obligation to support payment of the interest due on the notes issued by VIEs used in certain CRT transactions. Derivatives are reported at their fair value on our consolidated balance sheets. Changes in fair value on derivatives not in qualifying fair value hedge relationships are recorded as investment gains, net, on our consolidated statements of income. Derivatives in a net asset position, including net derivative interest receivable or payable, are reported as derivative assets, net, which is included in other assets on our consolidated balance sheets. Similarly, derivatives in a net liability position, including net derivative interest receivable or payable, are reported as derivative liabilities, net, which is included in other liabilities on our consolidated balance sheets. We offset fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral against fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting agreement. Non-cash collateral held is not recognized on our consolidated balance sheets as we do not obtain effective control over the collateral, and non-cash collateral posted is not derecognized from our consolidated balance sheets as we do not relinquish effective control over the collateral. Therefore, non-cash collateral held or posted is not presented as an offset against derivative assets or derivative liabilities on our consolidated balance sheets. See Note 10 for additional information on our collateralized arrangements. We evaluate whether financial instruments that we purchase or issue contain embedded derivatives. We generally elect to measure newly acquired or issued financial instruments that contain embedded derivatives at fair value, with changes in fair value recorded in earnings. On our consolidated statements of cash flows, cash flows related to derivatives are classified as either operating activities (such as periodic settlements of interest payments) or investing activities (such as variation margin payments and cash flows related to the acquisition and termination of derivatives) depending on the nature of the activity. Cash flows related to physical settlement of forward commitments accounted for as derivative instruments are classified as operating, investing, or financing activities depending on the financial instruments to which they relate. Hedge Accounting We apply fair value hedge accounting to certain single-family mortgage loans where we hedge the changes in fair value of these loans attributable to the designated benchmark interest rate, using interest-rate swaps. We also apply fair value hedge accounting to certain issuances of debt where we hedge the changes in fair value of the debt attributable to the designated benchmark interest rate, using interest-rate swaps. Under the portfolio layer method fair value hedge accounting strategy, we hedge the changes in fair value of a portion of a closed pool of single-family mortgage loans that is not expected to be affected by prepayments, defaults, and other events affecting the timing and amount of cash flows. As part of this strategy, we have also elected to measure the change in fair value of the hedged item on the basis of the benchmark rate component of the contractual coupon cash flows determined at the hedge inception and by assuming the hedged item has a term that reflects only the designated cash flows being hedged. We apply hedge accounting to qualifying hedge relationships. A qualifying hedge 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 hedge relationship. No amounts have been excluded from the assessment of hedge effectiveness. To assess hedge effectiveness, we use a statistical regression analysis. At inception of the hedge relationship, we prepare formal contemporaneous documentation of our risk management objective and strategies for undertaking the hedge. If a hedge relationship qualifies for fair value hedge accounting, all changes in fair value of the derivative hedging instrument, including interest accruals, are recognized in the same consolidated statements of income line item used to present the earnings effect of the hedged item. Therefore, changes in the fair value of the hedged item, mortgage loans and debt, attributable to the risk being hedged are recognized in interest income and interest expense, respectively, along with the changes in the fair value of the respective derivative hedging instruments. Changes in the fair value of the hedged item attributable to the risk being hedged are recognized as a cumulative basis adjustment against the mortgage loans and debt. The cumulative basis adjustments are amortized to the same consolidated statements of income line item used to present the changes in fair value of the hedged item using the effective interest method considering the contractual terms of the hedged item, with amortization beginning no later than the period in which hedge accounting was discontinued.

(2) Includes derivative instruments related to CRT transactions that are considered freestanding credit enhancements. (3) Represents counterparty netting and cash collateral netting. Derivative Counterparty Credit Risk Cleared derivatives refer to interest-rate swaps that the U.S. Commodity Futures Trading Commission has determined are subject to the central clearing requirement of the Dodd-Frank Act. Exchange-traded derivatives refer to standardized interest-rate futures contracts and options on futures contracts. OTC derivatives refer to those derivatives that are bilaterally negotiated with counterparties and settled with those counterparties. Our use of cleared derivatives, exchange-traded derivatives, and OTC derivatives exposes us to counterparty credit risk in the event our counterparties fail to meet their contractual obligations. We are required to post margin in connection with our derivatives transactions. The use of cleared and exchange-traded derivatives decreases our credit risk exposure to individual counterparties because a central counterparty is substituted for individual counterparties. OTC derivatives expose us to the credit risk of individual counterparties because transactions are executed and settled between us and each counterparty, exposing us to potential losses if a counterparty fails to meet its obligations. Our use of interest-rate swaps and option-based derivatives is subject to internal credit and legal reviews. On an ongoing basis, we review the credit fundamentals of all of our derivative counterparties, clearinghouses, and clearing members to confirm that they continue to meet our internal risk management standards. The majority of our interest-rate swaps are subject to the central clearing requirement. Changes in the value of open exchange- traded contracts and cleared derivatives are settled daily via payments made through the clearinghouse. We net our exposure to cleared derivatives by clearinghouse and clearing member. A downgrade in our credit ratings could cause the clearing members we use for our cleared and exchange-traded derivatives to demand additional collateral. Many of our transactions involving forward purchase and sale commitments of mortgage-related securities utilize the MBSD/ FICC as a clearinghouse. As a clearing member of the clearinghouse, we post margin to the MBSD/FICC and are exposed to the counterparty credit risk of the organization (including its clearing members). In June 2022, the FICC amended the MBSD clearing rules to provide that variation margin payments constitute daily settlement of exposure and not a component of the required fund deposit. As a result, for our forward purchase and sale commitments of mortgage-related securities transacted with MBSD/FICC, we changed the characterization of variation margin payments from posting of margin collateral to settlements. In the event a clearing member fails and causes losses to the MBSD/FICC clearing system, we could be subject to loss, as members are generally required to cover losses caused by defaulting members on a pro rata basis. It is difficult to estimate our maximum exposure under these transactions, as this would require an assessment of transactions that we and other members of the MBSD/FICC may execute in the future. We use master netting and collateral agreements to reduce our credit risk exposure to our OTC derivative counterparties for interest-rate swap and option-based derivatives. Master netting agreements provide for the netting of amounts receivable and payable from an individual counterparty, as well as posting of collateral in the form of cash, Treasury securities or agency mortgage-related or debt securities, or a combination of both by either the counterparty or us, depending on which party is in a liability position. Although it is our practice not to repledge assets held as collateral, these agreements may allow us or our counterparties to repledge all or a portion of the collateral. We have master netting agreements in place with all of our OTC derivative counterparties. On a daily basis, the market value of each counterparty's derivatives outstanding is calculated to determine the amount of our net credit exposure, which is equal to the market value of derivatives in a net gain position by counterparty after giving consideration to collateral posted. In the event a counterparty defaults on its obligations under the derivatives agreement and the default is not remedied in the manner prescribed in the agreement, we have the right under the agreement to sell the collateral. As a result, our use of master netting and collateral agreements reduces our exposure to our counterparties in the event of default. A significant majority of our net uncollateralized exposure to OTC derivative counterparties is concentrated with four counterparties, all of which were investment grade as of December 31, 2023. We regularly review the market value of securities pledged as collateral and derivative counterparty collateral posting thresholds, where applicable, in an effort to manage our exposure to losses. For certain OTC derivatives, the amount of collateral we pledge to counterparties related to our derivative instruments is determined after giving consideration to our credit rating. The aggregate fair value of our OTC derivative instruments containing credit-risk related contingent features, netted by counterparty, that were in a liability position was zero on December 31, 2023 and was $27 million on December 31, 2022 for which we posted cash and non-cash collateral of $17 million in the normal course of business. A downgrade in our credit ratings may trigger additional collateral requirements related to these OTC derivative instruments. If a downgrade in our credit ratings had triggered additional collateral requirements related to these OTC derivative instruments on December 31, 2023 and December 31, 2022, the maximum additional collateral we would have been required to post to our counterparties would be zero and $10 million, respectively. The table below presents offsetting and collateral information related to derivatives which are subject to enforceable master netting agreements or similar arrangements.

Offsetting [Abstract]
COLLATERALIZED AGREEMENTS AND OFFSETTING ARRANGEMENTS	NOTE 10 Collateralized Agreements Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase As an investor, we enter into arrangements to purchase securities under agreements to subsequently resell the identical or substantially the same securities to our counterparty. Our counterparties to these transactions are required to pledge the purchased securities as collateral for their obligation to repurchase those securities at a later date. While such transactions involve the legal transfer of securities, they are accounted for as secured financings because the transferor does not relinquish effective control over the securities transferred. These agreements may allow us to repledge all, or a portion, of the collateral pledged to us, and we may repledge such collateral periodically, although it is not typically our practice to repledge collateral that has been pledged to us. We consider the types of securities being pledged to us as collateral when determining how much we lend in transactions involving securities purchased under agreements to resell. Additionally, we regularly review the market values of these securities compared to amounts loaned in an effort to manage our exposure to losses and we reasonably expect the borrower to continue to replenish the collateral to meet the requirements of the contract. As of December 31, 2023, all of our securities purchased under agreements to resell were fully collateralized. We utilize the GSD/FICC as a clearinghouse to transact many of our trades involving securities purchased under agreements to resell, securities sold under agreements to repurchase, and other non-mortgage related securities. As a clearing member of GSD/FICC, we are required to post initial and variation margin payments and are exposed to the counterparty credit risk of GSD/FICC (including its clearing members). In the event a clearing member fails and causes losses to the GSD/FICC clearing system, we could be subject to the loss of the margin that we have posted to the GSD/FICC. Moreover, our exposure could exceed that amount, as members are generally required to cover losses caused by defaulting members on a pro rata basis. It is difficult to estimate our maximum exposure under these transactions, as this would require an assessment of transactions that we and other members of the GSD/FICC may execute in the future. We provide financing to investors in Freddie Mac securities to increase liquidity and expand the investor base for those securities. These transactions differ from the securities purchased under agreements to resell that we use for liquidity purposes as the counterparties we face may not be major financial institutions and we are exposed to greater counterparty credit risk for these institutions. As of both December 31, 2023 and December 31, 2022, $1.1 billion of our securities purchased under agreements to resell were used to provide financing to investors in Freddie Mac securities. Securities sold under agreements to repurchase are effectively collateralized borrowings where we sell securities with an agreement to repurchase such securities at a future date. We are required to pledge the sold securities to the counterparties to these transactions as collateral for our obligation to repurchase these securities at a later date. Similar to the securities purchased under agreements to resell transactions, these transactions involve the legal transfer of securities. However, they are accounted for as secured financings because the transferor does not relinquish effective control over the securities transferred. These agreements may allow our counterparties to repledge all or a portion of the collateral. We offset payables related to securities sold under agreements to repurchase against receivables related to securities purchased under agreements to resell when such amounts meet the conditions for balance sheet offsetting. The table below presents offsetting and collateral information related to securities purchased under agreements to resell, and securities sold under agreements to repurchase which are subject to enforceable master netting agreements or similar arrangements.

We repledged $0.4 billion and less than $0.1 billion of collateral at December 31, 2023 and December 31, 2022, respectively. The table below presents the remaining contractual maturity of our gross obligations for our securities sold under agreements to repurchase.

Stockholders' Equity Note [Abstract]
STOCKHOLDERS' EQUITY AND EARNINGS PER SHARE	Stockholders' Equity and Earnings Per Share Senior Preferred Stock Pursuant to the Purchase Agreement described in Note 2 , we issued one million shares of senior preferred stock to Treasury on September 8, 2008, in partial consideration of Treasury's commitment to provide funds to us. Shares of the senior preferred stock have a par value of $1 and have a stated value and initial liquidation preference of $1 billion, or $1,000 per share. The liquidation preference of the senior preferred stock is subject to adjustment. See Note 2 for a detailed discussion of the liquidation preference of the senior preferred stock. Treasury, as the holder of the senior preferred stock, is entitled to receive quarterly cash dividends, when, as, and if declared by our Board of Directors. The dividends we have paid to Treasury on the senior preferred stock have been declared by, and paid at the direction of, the Conservator, acting as successor to the rights, titles, powers, and privileges of the Board of Directors. See Note 2 for additional information concerning our senior preferred stock dividends. The senior preferred stock is senior to our common stock and all other outstanding series of our preferred stock, as well as any capital stock we issue in the future, as to both dividends and rights upon liquidation. The senior preferred stock provides that we may not, at any time, declare or pay dividends on, make distributions with respect to, redeem, purchase or acquire, or make a liquidation payment with respect to, any common stock or other securities ranking junior to the senior preferred stock unless: n Full cumulative dividends on the outstanding senior preferred stock (including any unpaid dividends added to the liquidation preference) have been declared and paid in cash and n All amounts required to be paid with the net proceeds of any issuance of capital stock for cash (as described below) have been paid in cash. Shares of the senior preferred stock are not convertible. Shares of the senior preferred stock have no general or special voting rights, other than those set forth in the certificate of designation for the senior preferred stock or otherwise required by law. The consent of holders of at least two-thirds of all outstanding shares of senior preferred stock is generally required to amend the terms of the senior preferred stock or to create any class or series of stock that ranks prior to or on parity with the senior preferred stock. We are not permitted to redeem the senior preferred stock prior to the termination of Treasury's funding commitment set forth in the Purchase Agreement; however, we are permitted to pay down the liquidation preference of the outstanding shares of senior preferred stock to the extent of accrued and unpaid dividends previously added to the liquidation preference and not previously paid down and quarterly commitment fees previously added to the liquidation preference and not previously paid down. Pursuant to the January 2021 Letter Agreement, we are permitted to issue common stock with aggregate gross proceeds of up to $70 billion after Treasury's exercise in full of its warrant to acquire 79.9% of our common stock and resolution of currently pending material litigation related to our conservatorship and the Purchase Agreement, and we are permitted to use the net proceeds of such issuance(s) to build capital. If we issue any other shares of capital stock for cash while the senior preferred stock is outstanding, the net proceeds of such issuances must be used to pay down the liquidation preference of the senior preferred stock; however, the liquidation preference of each share of senior preferred stock may not be paid down below $1,000 per share prior to the termination of Treasury's funding commitment. Following the termination of Treasury's funding commitment, we may pay down the liquidation preference of all outstanding shares of senior preferred stock at any time, in whole or in part. If, after termination of Treasury's funding commitment, we pay down the liquidation preference of each outstanding share of senior preferred stock in full, the shares will be deemed to have been redeemed as of the payment date. The table below provides a summary of our senior preferred stock outstanding at December 31, 2023. Table 11.1 - Senior Preferred Stock ( In millions , except initial liquidation preference price per share) Shares Authorized Shares Outstanding Total Par Value Initial Liquidation Preference Price per Share Total Liquidation Preference Non-draw Adjustments: 2008 1.00 1.00 $1.00 $1,000 $1,000 2017 — — — N/A 3,000 2019 — — — N/A 3,674 2020 — — — N/A 7,217 2021 — — — N/A 11,420 2022 — — — N/A 9,919 2023 — — — N/A 9,431 Total non-draw adjustments 1.00 1.00 1.00 45,661 Draw Adjustments: 2008 — — — N/A 13,800 2009 — — — N/A 36,900 2010 — — — N/A 12,500 2011 — — — N/A 7,971 2012 — — — N/A 165 2018 — — — N/A 312 Total draw adjustments — — — 71,648 Total senior preferred stock 1.00 1.00 $1.00 $117,309 No cash was received from Treasury under the Purchase Agreement in 2023 because we had positive net worth at December 31, 2022, March 31, 2023, June 30, 2023, and September 30, 2023 and, consequently, FHFA did not request a draw on our behalf in 2023. At December 31, 2023, our assets exceeded our liabilities under GAAP; therefore, no draw is being requested from Treasury under the Purchase Agreement. Common Stock Warrant Pursuant to the Purchase Agreement described in Note 2 , on September 7, 2008, we issued a warrant to purchase common stock to Treasury, in partial consideration of Treasury's commitment to provide funds to us. The warrant may be exercised in whole or in part at any time on or before September 7, 2028, by delivery to us of a notice of exercise, payment of the exercise price of $0.00001 per share, and the warrant. If the market price of one share of our common stock is greater than the exercise price, then, instead of paying the exercise price, Treasury may elect to receive shares equal to the value of the warrant (or portion thereof being canceled) pursuant to the formula specified in the warrant. Upon exercise of the warrant, Treasury may assign the right to receive the shares of common stock issuable upon exercise to any other person. We account for the warrant in permanent equity. At issuance on September 7, 2008, we recognized the warrant at fair value, and we do not recognize subsequent changes in fair value while the warrant remains classified in equity. We recorded an aggregate fair value of $2.3 billion for the warrant as a component of additional paid-in-capital. We derived the fair value of the warrant using a modified Black-Scholes model. If the warrant is exercised, the stated value of the common stock issued will be reclassified to common stock on our consolidated balance sheets. The warrant was determined to be in-substance non-voting common stock, because the warrant's exercise price of $0.00001 per share is considered non-substantive (compared to the market price of our common stock). As a result, the shares associated with the warrant are included in the computation of basic and diluted earnings per share. The weighted average shares of common stock for the years ended December 31, 2023, 2022, and 2021 included shares of common stock that would be issuable upon full exercise of the warrant issued to Treasury. Preferred Stock We have the option to redeem our preferred stock on specified dates, at their redemption price plus dividends accrued through the redemption date. However, without the consent of Treasury, we are restricted from making payments to purchase or redeem preferred stock as well as paying any preferred dividends, other than dividends on the senior preferred stock. All 24 classes of preferred stock are perpetual and non-cumulative, and carry no significant voting rights or rights to purchase additional Freddie Mac stock or securities. Costs incurred in connection with the issuance of preferred stock are charged to additional paid-in capital. The table below provides a summary of our preferred stock outstanding at their redemption values at December 31, 2023.

Beginning on July 1, 2023, those classes transitioned from three-month LIBOR and 12-month LIBOR to spread-adjusted three-month CME Term SOFR and spread-adjusted 12-month CME Term SOFR, respectively. (2) Dividend rate resets quarterly and is equal to the sum of spread-adjusted three-month CME Term SOFR plus 1% divided by 1.377, and is capped at 9.00%. (3) Issued through private placement. (4) Dividend rate resets quarterly and is equal to the sum of spread-adjusted three-month CME Term SOFR plus 1% divided by 1.377, and is capped at 7.50%. (5) Dividend rate resets on January 1 every five years after January 1, 2005 based on a five-year Constant Maturity Treasury rate, and is capped at 11.00%. Optional redemption on December 31, 2004 and on December 31 every five years thereafter. (6) Dividend rate resets on April 1 every two years after April 1, 2003 based on the two-year Constant Maturity Treasury rate plus 0.10%, and is capped at 11.00%. Optional redemption on March 31, 2003 and on March 31 every two years thereafter. (7) Dividend rate resets on April 1 every year based on spread-adjusted 12-month CME Term SOFR minus 0.20%, and is capped at 11.00%. Optional redemption on March 31, 2003 and on March 31 every year thereafter. (8) Dividend rate resets on July 1 every two years after July 1, 2003 based on the two-year Constant Maturity Treasury rate plus 0.20%, and is capped at 11.00%. Optional redemption on June 30, 2003 and on June 30 every two years thereafter. (9) Dividend rate resets quarterly and is equal to the sum of spread-adjusted three-month CME Term SOFR plus 0.50% but not less than 4.00% . (10) Dividend rate is set at an annual fixed rate of 8.375% from December 4, 2007 through December 31, 2012. For the period beginning on or after January 1, 2013, dividend rate resets quarterly and is equal to the higher of: (a) the sum of spread-adjusted three-month CME Term SOFR plus 4.16% per annum; or (b) 7.875% per annum. Optional redemption on December 31, 2012 and on December 31 every five years thereafter . Stock-Based Compensation Following the implementation of the conservatorship in September 2008, we suspended the operation of and/or ceased making grants under our stock-based compensation plans. Under the Purchase Agreement, we cannot issue any new options, rights to purchase, participations or other equity interests without Treasury's prior approval. We did not repurchase or issue any of our common shares or non-cumulative preferred stock during 2023 and 2022. At both December 31, 2023 and December 31, 2022, no RSUs or stock options were outstanding. There were 41,160 shares of restricted stock outstanding at both December 31, 2023 and December 31, 2022. Earnings Per Share Basic earnings per common share is computed as net income attributable to common stockholders divided by the weighted average common shares for the period. The weighted average common shares for the period includes the weighted average number of shares that are associated with the warrant for our common stock issued to Treasury pursuant to the Purchase Agreement. These shares are included since the warrant is unconditionally exercisable by the holder at a minimal cost. We deduct dividends or increases in liquidation preference attributable to the senior preferred stock from net income attributable to common stockholders in the period in which such amounts are determinable. Our diluted earnings per common share is the same as our basic earnings per common share because we had no common equivalent shares outstanding during the periods presented which could have had a dilutive or antidilutive effect. Dividends and Dividend Restrictions We did not declare or pay any dividends in 2023, 2022, and 2021 on our common stock, senior preferred stock, or any other outstanding series of Freddie Mac preferred stock. Our payment of dividends is subject to the following restrictions: n Restrictions Relating to the Conservatorship - The Conservator has prohibited us from paying any dividends on our common stock or on any series of our preferred stock (other than the senior preferred stock). FHFA has instructed our Board of Directors that it should consult with and obtain the approval of FHFA before taking actions involving dividends. In addition, FHFA has adopted a regulation prohibiting us from making capital distributions during conservatorship, except as authorized by the Director of FHFA. n Restrictions Under the Purchase Agreement - The Purchase Agreement prohibits us and any of our subsidiaries from declaring or paying any dividends on Freddie Mac equity securities (other than with respect to the senior preferred stock or warrant) without the prior written consent of Treasury. n Restrictions Under the GSE Act - Under the GSE Act, FHFA has authority to prohibit capital distributions, including payment of dividends, if we fail to meet applicable capital requirements. However, our capital requirements have been suspended during conservatorship. n Restrictions Under our Charter - Without regard to our capital classification, we must obtain prior written approval of FHFA to make any capital distribution that would decrease total capital to an amount less than the risk-based capital level or that would decrease core capital to an amount less than the minimum capital level. As noted above, our capital requirements have been suspended during conservatorship. n Restrictions Relating to Preferred Stock - Payment of dividends on our common stock is also subject to the prior payment of dividends on our 24 series of preferred stock and one series of senior preferred stock, representing an aggregate of 464,170,000 shares and 1,000,000 shares outstanding, respectively, as of December 31, 2023. Payment of dividends on all outstanding preferred stock, other than the senior preferred stock, is subject to the prior payment of dividends on the senior preferred stock. Delisting of Common Stock and Preferred Stock from NYSE On July 8, 2010, we delisted our common stock and 20 previously listed classes of preferred stock from the NYSE as directed by our Conservator. Our common stock and the classes of preferred stock that were previously listed on the NYSE are traded exclusively in the OTCQB Marketplace. Shares of our common stock trade under the ticker symbol FMCC . We expect that our common stock and the previously listed classes of preferred stock will continue to trade in the OTCQB Marketplace so long as market makers demonstrate an interest in trading the common and preferred stock.

INCOME TAXES	Income Taxes Income Tax Expense Total income tax expense includes: n Current income tax expense, which represents the amount of federal tax paid or payable to (or refundable from) the Internal Revenue Service, including interest and penalties and amounts accrued for unrecognized tax benefits, if any, and n Deferred income tax expense, which represents the net change in the deferred tax asset or liability balance during the year, including any change in the valuation allowance. The table below presents the components of our federal income tax expense for the past three years. We are exempt from state and local income taxes. Table 13.1 - Federal Income Tax Expense Year Ended December 31, (In millions) 2023 2022 2021 Current income tax expense ($1,003) ($1,749) ($2,617) Deferred income tax expense (1,658) (528) (473) Total income tax expense ($2,661) ($2,277) ($3,090) The table below presents the reconciliation between our federal statutory income tax rate and our effective tax rate for the past three years.

Under this method, deferred tax assets and liabilities are recognized based upon the expected future tax consequences of existing temporary differences between the financial reporting and the tax reporting basis of assets and liabilities using enacted statutory tax rates as well as tax net operating loss and tax credit carryforwards, if any. To the extent tax laws change, deferred tax assets and liabilities are adjusted in the period that the tax change is enacted. The realization of our net deferred tax assets is dependent upon the generation of sufficient taxable income. The table below presents the balance of significant deferred tax assets and liabilities at December 31, 2023 and December 31, 2022. The valuation allowance relates to capital loss carryforwards included in Other items, net that we expect to expire unused. Table 13.3 - Deferred Tax Assets and Liabilities (In millions) December 31, 2023 December 31, 2022 Deferred tax assets: Deferred fees $1,821 $2,197 Basis differences related to derivative instruments 1,042 1,745 Credit related items and allowance for loan losses 863 1,457 Basis differences related to assets held-for-investment and held-for-sale 696 1,549 Other items, net 439 178 Total deferred tax assets 4,861 7,126 Deferred tax liabilities: Basis differences related to fair value hedge accounting (749) (1,315) Other items, net (18) — Total deferred tax liabilities (767) (1,315) Valuation allowance (18) (34) Deferred tax assets, net $4,076 $5,777 Valuation Allowance A valuation allowance is recorded to reduce the net deferred tax asset when it is more likely than not that all or part of our tax benefits will not be realized. On a quarterly basis, we determine whether a valuation allowance is necessary. In doing so, we consider all evidence available, both positive and negative, in determining whether, based on the weight of the evidence, it is more likely than not that the net deferred tax asset will be realized. We are not permitted to consider in our analysis the impacts proposed legislation may have on our business because the timing and certainty of those actions are unknown and beyond our control. Based on all positive and negative evidence available at December 31, 2023, we determined that it is more likely than not that our net deferred tax assets, except for the deferred tax asset related to our capital loss carryforwards, will be realized. A valuation allowance of $18 million has been recorded against our capital loss carryforward deferred tax asset. Unrecognized Tax Benefits We recognize a tax position taken or expected to be taken (and any associated interest and penalties) if it is more likely than not that it will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. We measure the tax position at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. We evaluated all income tax positions and determined that there were no uncertain tax positions that required reserves as of December 31, 2023.

Segment Reporting [Abstract]
SEGMENT REPORTING	Segment Reporting As shown in the table below, we have two reportable segments, Single-Family and Multifamily. Segment Description Single-Family Reflects results from our purchase, securitization, and guarantee of single-family loans, our investments in single-family loans and mortgage-related securities, the management of Single-Family mortgage credit risk and market risk, and any results of our treasury function that are not allocated to each segment. Multifamily Reflects results from our purchase, securitization, and guarantee of multifamily loans, our investments in multifamily loans and mortgage-related securities, and the management of Multifamily mortgage credit risk and market risk. Segment Allocations and Results Our measure of segment profit and loss for each segment is net income and comprehensive income calculated using the same accounting policies we use to prepare our general purpose financial statements in conformity with GAAP. The results of each reportable segment include directly attributable revenues and expenses. We allocate interest expense and other funding and hedging-related costs and returns on certain investments to each reportable segment using a funds transfer pricing process. We fully allocate to each reportable segment administrative expenses and other centrally-incurred costs that are not directly attributable to a particular segment using various methodologies depending on the nature of the expense.

Risks and Uncertainties [Abstract]
CONCENTRATION OF CREDIT AND OTHER RISKS	Concentration of Credit and Other Risks Concentrations of credit risk may arise when we do business with a number of customers or counterparties that engage in similar activities or have similar economic characteristics that make them vulnerable in similar ways to changes in industry conditions, which could affect their ability to meet their contractual obligations. Concentrations of credit risk may also arise when there are a limited number of counterparties in a certain industry. Based on our assessment of business conditions that could affect our financial results, we have determined that concentrations of credit risk exist among certain borrowers (including geographic concentrations), loan sellers and servicers, credit enhancement providers, and other investment counterparties. In the sections below, we discuss our concentration of credit risk for each of the groups to which we are exposed. For a discussion of our derivative counterparties, as well as related master netting and collateral agreements, see Note 9 . For a discussion of securities purchased under agreements to resell and other collateralized arrangements, see Note 10 . Single-Family Mortgage Portfolio Single-family borrowers are primarily affected by house prices and interest rates, which are influenced by economic factors. Geographic concentrations may increase the exposure of our portfolio to credit risk, as regional economic conditions may affect a borrower's ability to repay and the underlying property value. The table below summarizes the concentration by geographic area of our Single-Family mortgage portfolio. See Note 3 , Note 4 , Note 5 , and Note 6 for additional information about credit risk associated with single-family loans that we hold or guarantee.

(2) Multifamily Mortgage Portfolio Numerous factors affect the credit risk related to multifamily borrowers, including effective rents paid and capitalization rates for the mortgaged property. Effective rents paid vary among geographic regions of the United States. Geographic concentrations may increase the exposure of our portfolio to credit risk, as regional economic conditions may affect a multifamily borrower's ability to repay and the underlying property value. The a verage UPB for multifamily loans is significantly larger than for single-family loans and, therefore, individual defaults for multifamily borrowers can result in more significant losses. The table below summarizes the concentration by geographic area of our Multifamily mortgage portfolio. Table 15.2 - Concentration of Credit Risk of Our Multifamily Mortgage Portfolio December 31, 2023 (Dollars in millions) Portfolio UPB % of Portfolio Delinquency Rate (1) Region (2)(3) : West $109,815 25 % 0.16 % Northeast 107,326 24 0.52 Southwest 91,406 21 0.26 Southeast 88,762 20 0.10 North Central 43,488 10 0.40 Total $440,797 100 % 0.28 State (3) : California $58,186 13 % 0.07 Texas 56,231 13 0.28 Florida 38,440 9 0.03 New York 33,815 8 1.13 Georgia 18,178 4 0.01 All other 235,947 53 0.27 Total $440,797 100 % 0.28 (1) Based on loans two monthly payments or more delinquent or in foreclosure.

(3) The UPB of loans collateralized by properties located in multiple regions or states are reported entirely in the region or state with the largest underlying collateral UPB as of origination. In the Multifamily mortgage portfolio, concentration of credit risk depends on the legal structure of the investments we hold. Our exposure to credit risk in our senior subordinate securitization products is minimal, as the expected credit risk is generally absorbed by the subordinate tranches, which are typically sold to third-party investors. As a result, our Multifamily mortgage credit risk is primarily related to loans that have not been securitized. See Note 3 , Note 4 , Note 5 , and Note 6 for additional information about credit risk associated with multifamily loans that we hold or guarantee. Single-Family Sellers and Servicers We acquire a significant portion of our Single-Family loan purchase volume from several large sellers. Our top 10 sellers provided approximately 55% of our Single-Family purchase volume, including two sellers that each provided 10% or more of our Single-Family purchase volume during 2023. We purchase single-family loans from both depository and non-depository sellers. Non-depository institutions may not have the same financial strength or operational capacity, or be subject to the same level of regulatory oversight, as large depository institutions. Our top five non-depository sellers provided approximately 41% of our Single-Family purchase volume during 2023. If we discover that the representations or warranties related to a loan were breached (i.e., that contractual standards were not followed), we can exercise certain contractual remedies to mitigate our actual or potential credit losses. These contractual remedies may include, but are not limited to, the ability to require the seller or servicer to repurchase the loan at its current UPB, reimburse us for losses realized with respect to the loan after consideration of any other recoveries, and/or indemnify us. Our current remedies framework provides for the categorization of loan origination defects for loans with settlement dates on or after January 1, 2016. Among other items, the framework provides that "significant defects" may result in a repurchase request or a repurchase alternative, such as recourse or indemnification. Under our current selling and servicing representation and warranty framework for our mortgage loans, we relieve sellers of repurchase obligations for breaches of certain selling representations and warranties for certain types of loans, including: n Loans that have established an acceptable payment history for 36 months (12 months for relief refinance loans) of consecutive, on-time payments after purchase, subject to certain exclusions and n Loans that have satisfactorily completed a quality control review. Solely for the purpose of determining whether the acceptable payment history requirements are met, payments due during the COVID-19-related forbearance period are considered to have been made on time, provided that the mortgage was reported by the servicer as having entered into a COVID-19-related forbearance plan between March 13, 2020 and October 31, 2023 and met certain other criteria as described in our Guide. An independent dispute resolution process for alleged breaches of selling or servicing representations and warranties on our loans allows for a neutral third party to render a decision on demands that remain unresolved after the existing appeal and escalation processes have been exhausted. As of December 31, 2023, the UPB of loans subject to our repurchase requests issued to our Single-Family sellers and servicers was approximately $0.5 billion (this figure includes repurchase requests for which appeals were pending). During 2023, we recovered amounts with respect to $1.5 billion in UPB of loans subject to our repurchase requests. The ultimate amounts of recovery payments we receive from seller/servicers related to their repurchase obligations may be significantly less than the amount of our estimates of potential exposure to losses. Our expected credit losses for exposure to seller/servicers for their repurchase obligations are considered in our allowance for credit losses. See Note 6 for further information. We are also exposed to the risk that servicers might fail to service loans in accordance with the contractual requirements, resulting in increased credit losses. For example, our servicers have an active role in our loss mitigation efforts, and we, therefore, have exposure to them to the extent a decline in their performance results in a failure to realize the anticipated benefits of the loss mitigation plans. Since we do not have our own servicing operation, if our servicers lack appropriate controls, experience a failure in their controls, or experience an operating disruption in their ability to service loans, our business and financial results could be adversely affected. Significant portions of our single-family loans are serviced by several large servicers. Our top 10 servicers serviced approximately 53% of our Single-Family mortgage portfolio, including one servicer that serviced 10% or more of our Single-Family mortgage portfolio as of December 31, 2023. We utilize both depository and non-depository servicers for single-family loans. Some of these non-depository servicers service a large share of our loans. As of December 31, 2023, approximately 25% of our Single-Family mortgage portfolio, excluding loans for which we do not exercise control over the associated servicing, was serviced by our five largest non-depository servicers, on a combined basis. We routinely monitor the performance of our largest non-depository servicers. For our mortgage-related securities, we guarantee the payment of principal and interest, and when the underlying borrowers do not make their mortgage payments, our Guide generally requires Single-Family servicers to advance the missed mortgage interest payments for up to 120 days. After this time, Freddie Mac will make the missed mortgage principal and interest payments until the mortgages are no longer held by the securitization trust. In addition to principal and interest payments, borrowers are also responsible for other expenses such as property taxes and homeowner's insurance premiums. When borrowers do not pay these expenses, our Guide generally requires Single-Family servicers to advance the funds for these expenses in order to protect or preserve our interest in or legal right to the properties. These advances are ultimately collectible from the borrowers. If the borrowers reperform through loan workout activities, the missed payments and incurred expenses will be collected from them. We will reimburse the servicers for the advanced amounts when uncollected from the borrowers at completion of foreclosures or foreclosure alternatives. On August 17, 2022, FHFA and Ginnie Mae issued a joint announcement of their updated minimum financial eligibility requirements for Enterprise seller/servicers and Ginnie Mae issuers. Freddie Mac announced the updated changes on September 21, 2022. The new requirements contain changes related to incorporating enhanced definitions of capital and liquidity, reducing the procyclicality of the current liquidity requirements, and incorporating lessons learned from the pandemic. They also include higher supplemental requirements applicable only to large non-depositories, defined as non-depositories having $50 billion or more of total single-family servicing UPB, as well as a new origination liquidity requirement for sellers that originate greater than $1 billion in single-family first lien mortgages in the most recent calendar year. The majority of the requirements became effective on September 30, 2023. Multifamily Sellers and Servicers We acquire a significant portion of our Multifamily loan purchase and guarantee volume from several large sellers. Our top 10 sellers provided approximately 74% of our Multifamily purchase and guarantee volume, including three sellers that each provided 10% or more of our Multifamily purchase and guarantee volume during 2023. Significant portions of our multifamily loans are serviced by several large servicers. Our top 10 servicers serviced approximately 78% of our Multifamily mortgage portfolio, including three servicers that each serviced 10% or more of our Multifamily mortgage portfolio as of December 31, 2023. Multifamily loans utilize both primary and master servicers. Primary servicers service unsecuritized mortgage loans and are also typically engaged by master servicers to service on their behalf the mortgage loans underlying securitizations. For a majority of our K Certificate securitizations, we utilize one of three large financial depository institutions as master servicer. For our other securitization products and a smaller number of K Certificate securitizations, we serve as master servicer. Multifamily primary servicers discussed above present potential operational risk and impact to the borrowers if the servicing needs to be transferred to another servicer. We also rely on master servicers of our multifamily securitization transactions to advance funds in the event of payment shortfalls, including principal and interest payments related to loans in forbearance. In instances where payment shortfalls occur, the master servicer is required to make advances as long as such advances have not been deemed unrecoverable. For multifamily loans purchased and held in our mortgage-related investments portfolio, the primary servicers are not required to advance funds in the event of payment shortfalls and, therefore, do not present significant counterparty credit risk from this source. Credit Enhancement Providers We have counterparty credit risk relating to the potential insolvency of, or nonperformance by, mortgage insurers that insure single-family loans we purchase or guarantee. We also have similar exposure to insurers and reinsurers through our ACIS and other insurance transactions where we purchase insurance policies as part of our CRT activities. We evaluate the recovery and collectability from mortgage insurers as part of the estimate of our allowance for credit losses. See Note 6 for additional information. As of December 31, 2023, mortgage insurers provided primary mortgage insurance coverage with maximum loss limits of $165.7 billion for $637.0 billion of UPB in connection with our Single-Family mortgage portfolio. These amounts are based on gross coverage without regard to netting of coverage that may exist to the extent an affected loan is covered under other types of insurance. Changes in our expectations related to recovery and collectability from our credit enhancement providers may affect our estimates of expected credit losses, perhaps significantly. The table below summarizes the concentration of mortgage insurer counterparties who provided 10% or more of our overall primary mortgage insurance coverage. Table 15.3 - Primary Mortgage Insurer Concentration Mortgage Insurance Coverage (1) Mortgage Insurer December 31, 2023 Mortgage Guaranty Insurance Corporation 18 % Arch Mortgage Insurance Company 18 Radian Guaranty Inc. 17 Essent Guaranty, Inc. 17 Enact 16 National Mortgage Insurance Corporation 14 Total 100 % (1) Coverage amounts exclude coverage primarily related to certain loans for which we do not control servicing, and may include coverage provided by affiliates and subsidiaries of the counterparty. As part of our ACIS transactions, we regularly obtain insurance coverage from global insurers and reinsurers. These transactions incorporate several features designed to increase the likelihood that we will recover on the claims we file with the insurers and reinsurers. In each transaction, we require the individual insurers and reinsurers to post collateral to cover portions of their exposure, which helps to promote certainty and timeliness of claim payment. While private mortgage insurance companies are required to be monoline (i.e., to participate solely in the mortgage insurance business, although the holding company may be a diversified insurer), many of our insurers and reinsurers in these transactions participate in multiple types of insurance businesses, which helps diversify their risk exposure. Other Investment Counterparties We are exposed to the non-performance of counterparties relating to other investments (including non-mortgage-related securities and cash equivalents) transactions, including those entered into on behalf of our securitization trusts. Our policies require that the counterparty be evaluated using our internal counterparty rating model prior to our entering such transactions. We monitor the financial strength of our counterparties to these transactions and may use collateral maintenance requirements to manage our exposure to individual counterparties. The permitted term and dollar limits for each of these transactions are also based on the counterparty's financial strength. Our other investments (including non-mortgage-related securities and cash equivalents) counterparties are primarily major institutions, including other GSEs, Treasury, the Federal Reserve Bank of New York, GSD/FICC, highly-rated supranational institutions, depository and non-depository institutions, brokers and dealers, and government money market funds. As of December 31, 2023, including amounts related to our consolidated VIEs, the balance in our other investments portfolio was $147.2 billion. The balance consists primarily of cash, securities purchased under agreements to resell, U.S. Treasury securities, cash deposited with the Federal Reserve Bank of New York, and secured lending activities.

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	Fair Value Disclosures The accounting guidance for fair value measurements and disclosures defines fair value, establishes a framework for measuring fair value and sets forth disclosure requirements regarding fair value measurements. This guidance applies whenever other accounting guidance requires or permits assets or liabilities to be measured at fair value. Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement assumes that the transaction to sell the asset or transfer the liability takes place either in the principal market for the asset or liability, or, in the absence of a principal market, in the most advantageous market for the asset or liability. We use fair value measurements for the initial recording of certain assets and liabilities and periodic remeasurement of certain assets and liabilities on a recurring or non-recurring basis. Fair Value Measurements The accounting guidance for fair value measurements and disclosures establishes a three-level fair value hierarchy that prioritizes the inputs into the valuation techniques used to measure fair value. The levels of the fair value hierarchy are defined as follows in priority order: n Level 1 - Inputs to the valuation techniques are based on quoted prices in active markets for identical assets or liabilities. n Level 2 - Inputs to the valuation techniques are based on observable inputs other than quoted prices in active markets for identical assets or liabilities. n Level 3 - One or more inputs to the valuation technique are unobservable and significant to the fair value measurement. We use quoted market prices and valuation techniques that seek to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs. Our inputs are based on the assumptions a market participant would use in valuing the asset or liability. Assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. Valuation Risk and Controls Over Fair Value Measurements Valuation risk is the risk that fair values used for financial disclosures, risk metrics, and performance measures do not reasonably reflect market conditions and prices. We designed our control processes so that our fair value measurements are appropriate and reliable, that they are based on observable inputs where possible, and that our valuation approaches are consistently applied and the assumptions and inputs are reasonable. Our control processes provide a framework for segregation of duties and oversight of our fair value methodologies, techniques, validation procedures, and results. Groups within our Finance Division, independent of our business functions, execute and validate the valuation processes and are responsible for determining the fair values of the majority of our financial assets and liabilities. In determining fair value, we consider the credit risk of our counterparties in estimating the fair values of our assets and our own credit risk in estimating the fair values of our liabilities. The fair values determined by our Finance Division are further verified by an independent group within our ERM Division. The independent validation procedures performed by the ERM Division are intended to monitor that the prices we receive from third parties are consistent with our observations of market activity, and that fair value measurements developed using internal data reflect the assumptions that a market participant would use in pricing our assets and liabilities. These validation procedures include performing a daily price review and a monthly independent verification of fair value measurements through independent modeling, analytics, and comparisons to other market source data, if available. If we are unable to validate the reasonableness of a given price, we ultimately do not use that price for fair value measurements on our consolidated financial statements. These procedures are risk-based and are executed before we finalize the prices used in preparing our fair value measurements for our financial statements. In addition to performing the validation procedures noted above, the ERM Division provides independent risk governance over all valuation processes by establishing and maintaining a corporate-wide valuation risk policy. The ERM Division also independently reviews significant judgments, methodologies, and valuation techniques to monitor compliance with established policies. Our Valuation Risk Committee, which includes representation from our business lines, the ERM Division, and the Finance Division, provides senior management's governance over valuation processes, methodologies, controls, and fair value measurements. Identified exceptions are reviewed and resolved through the verification process and reviewed at the Valuation Risk Committee. Where models are employed to assist in the measurement and verification of fair values, changes made to those models during the period are reviewed and approved according to the corporate model change governance process, with material changes reviewed at the Valuation Risk Committee. Inputs used by models are regularly updated for changes in the underlying data, assumptions, valuation inputs, and market conditions and are subject to the valuation controls noted above. Use of Third-Party Pricing Data in Fair Value Measurement Many of our valuation techniques use, either directly or indirectly, data provided by third-party pricing services or dealers. The techniques used by these pricing services and dealers to develop the prices generally are either: n A comparison to recent transactions involving the instrument or transactions involving instruments with similar collateral and risk profiles, adjusted as necessary based on specific characteristics of the asset or liability being valued; or n Industry-standard modeling, such as a discounted cash flow model. The prices provided by the pricing services and dealers reflect their observations and assumptions related to market activity, including risk premiums and liquidity adjustments. The models and related assumptions used by the pricing services and dealers are owned and managed by them and, in many cases, the significant inputs used in the valuation techniques are not reasonably available to us. However, we have an understanding of the processes and assumptions used to develop the prices based on our ongoing due diligence, which includes discussions with our pricing services and dealers at least annually and often more frequently. We believe that the procedures executed by the pricing services and dealers, combined with our internal verification and analytical procedures, provide assurance that the prices used in our financial statements comply with the accounting guidance for fair value measurements and disclosures and reflect the assumptions that a market participant would use in pricing our assets and liabilities. The price quotes we receive are non-binding both to us and to our counterparties. In many cases, we receive quotes from third-party pricing services or dealers and use those prices without adjustment. For a large majority of the assets and liabilities we value using pricing services and dealers, we obtain quotes from multiple external sources and use the median of the prices to measure fair value. This technique is referred to below as "median of external sources." The significant inputs used in the fair value measurement of assets and liabilities that are valued using the median of external sources pricing technique are the third-party quotes. Significant increases (decreases) in any of the third-party quotes in isolation may result in a significantly higher (lower) fair value measurement. In limited circumstances, we may be able to receive pricing information from only a single external source. This technique is referred to below as "single external source." Valuation Techniques The following table contains a description of the valuation techniques we use for fair value measurement and disclosure; the significant inputs used in those techniques (if applicable); the classification within the fair value hierarchy; and, for those measurements that we report on our consolidated balance sheets and are classified as Level 3 of the hierarchy, a narrative description of the uncertainty of the fair value measurement to changes in significant unobservable inputs. Although the uncertainties of the unobservable inputs are discussed below in isolation, interrelationships exist among the inputs such that a change in one unobservable input can result in a change to one or more of the other inputs. For example, the most common interrelationship that affects the majority of our fair value measurements is between future interest rates, prepayment speeds, and probabilities of default. Generally, a change in the assumption used for future interest rates results in a directionally opposite change in the assumption used for prepayment speeds and a directionally similar change in the assumption used for probabilities of default. Each technique discussed below may not be used in a given reporting period, depending on the composition of our assets and liabilities measured at fair value and relevant market activity during that period. Instrument Valuation Technique Classification in the Fair Value Hierarchy Investment Securities U.S. Treasury Securities Quoted prices in active markets Level 1 Mortgage-related securities Majority of agency securities Median of external sources Level 2 Certain other agency securities Single external source Level 2 or 3 Certain securities with limited market activity Discounted cash flows or risk metric pricing. Level 3 Mortgage Loans Single-Family loans GSE securitization market Benchmark security pricing for actively traded mortgage-related securities with similar characteristics, adjusting for the value of our guarantee fee and our credit obligation related to performing our guarantee (see Guarantee obligations).

Level 2 or 3 Whole loan market Median of external sources, referencing market activity for deeply delinquent and modified loans, where available. Level 3 Certain held-for-investment Internal models that estimate the fair value of the underlying collateral for impaired loans. Significant inputs used by our internal models include REO disposition, short sale, and third-party sale values, combined with mortgage loan level characteristics using the repeat housing sales index to estimate the current fair value of the mortgage loan. Significant increases (decreases) in the historical average sales proceeds per mortgage loan in isolation would result in significantly higher (lower) fair value measurements.

Assets Measured at Fair Value on a Non-Recurring Basis We may be required, from time to time, to measure certain assets at fair value on a non-recurring basis. These adjustments usually result from the application of lower-of-cost-or-fair-value accounting or an allowance for credit losses based on the fair value of the underlying collateral. Certain of the fair values in the tables below were not obtained as of the period end, but were obtained during the period. The table below presents assets measured on our consolidated balance sheets at fair value on a non-recurring basis.

Fair Value of Financial Instruments The table below presents the carrying value and estimated fair value of our financial instruments. For certain types of financial instruments, such as cash and cash equivalents, securities purchased under agreements to resell, secured lending, and certain debt, the carrying value on our GAAP balance sheets approximates fair value, as these assets and liabilities are short-term in nature and have limited fair value volatility.

(4) For other assets, includes advances to lenders, secured lending, and loan commitments. For other liabilities, includes loan commitments. (5) Fair Value Option We elected the fair value option for certain mortgage loans and loan commitments and certain debt issuances. Mortgage Loans and Loan Commitments We elected the fair value option for certain fixed-rate multifamily loan purchase commitments and certain multifamily loans that were acquired for securitization to offset the changes in fair value of the derivatives that we use to economically hedge the interest rate risk of the loans and commitments. The multifamily loans are classified either as held-for-investment or as held-for-sale on our consolidated balance sheets based on management's intent and ability and are measured at fair value on a recurring basis, with subsequent gains or losses related to changes in fair value (net of accrued interest income) reported in investment gains, net, on our consolidated statements of income. We elected to report separately the portion of the changes in fair value of the loans related to accrued interest from the remaining changes in fair value. Related interest income continues to be reported, based on the stated terms of the loans, as interest income on our consolidated statements of income. The multifamily loan commitments are included in other assets or liabilities on our consolidated balance sheets and are measured at fair value on a recurring basis, with subsequent gains or losses related to changes in fair value included in investment gains, net, on our consolidated statements of income Debt of Consolidated Trusts and Debt of Freddie Mac We elected the fair value option on debt that contains embedded derivatives, including certain STACR and SCR debt notes, and certain other debt issuances. Fair value changes are recorded in investment gains, net, on our consolidated statements of income.

Commitments and Contingencies Disclosure [Abstract]
LEGAL CONTINGENCIES	Legal Contingencies We are involved, directly or indirectly, in a variety of legal and regulatory proceedings arising from time to time in the ordinary course of business (including, among other things, contractual disputes, personal injury claims, employment-related litigation, and other legal proceedings incidental to our business) and in connection with the conservatorship and Purchase Agreement. We are frequently involved, directly or indirectly, in litigation involving mortgage foreclosures. From time to time, we are also involved in proceedings arising from our termination of a seller's or servicer's eligibility to sell loans to, and/or service loans for, us. In these cases, the former seller or servicer sometimes seeks damages against us for wrongful termination under a variety of legal theories. In addition, we are sometimes sued in connection with the origination or servicing of loans. These suits typically involve claims alleging wrongful actions of sellers and servicers. Our contracts with our sellers and servicers generally provide for indemnification of Freddie Mac against liability arising from sellers' and servicers' wrongful actions with respect to loans sold to or serviced for Freddie Mac. Litigation claims and proceedings of all types are subject to many uncertainties (including appeals and procedural filings), and there can be no assurance as to the ultimate outcome of those actions (including the matters described below). In accordance with the accounting guidance for contingencies, we reserve for litigation claims and assessments asserted or threatened against us when a loss is probable (as defined in such guidance) and the amount of the loss can be reasonably estimated. The actual costs of resolving legal actions may be substantially higher or lower than the amounts accrued for those actions. It is not possible for us to predict the actions the U.S. government (including Treasury and FHFA) might take in response to any ruling or finding in any of these lawsuits or any future lawsuits. However, it is possible that we could be adversely affected by these events, including, for example, by changes to the Purchase Agreement, or any resulting actual or perceived changes in the level of U.S. government support for our business. Putative Securities Class Action Lawsuit: Ohio Public Employees Retirement System vs. Freddie Mac, Syron, Et Al. This putative securities class action lawsuit was filed against Freddie Mac and certain former officers on January 18, 2008 in the U.S. District Court for the Northern District of Ohio purportedly on behalf of a class of purchasers of Freddie Mac stock from August 1, 2006 through November 20, 2007. FHFA later intervened as Conservator, and the plaintiff amended its complaint on several occasions. The plaintiff alleged, among other things, that the defendants violated federal securities laws by making false and misleading statements concerning our business, risk management, and the procedures we put into place to protect the company from problems in the mortgage industry. The plaintiff seeks unspecified damages and interest, and reasonable costs and expenses, including attorney and expert fees. In August 2018, the District Court denied the plaintiff's motion for class certification. On April 6, 2023, the Sixth Circuit reversed the District Court's September 17, 2020 decision to grant the plaintiff's request for summary judgment and enter final judgment in favor of Freddie Mac and other defendants. The Sixth Circuit remanded the case to the District Court for further proceedings. The District Court scheduled the trial to begin on October 21, 2024. Litigation Concerning the Purchase Agreement in the U.S. District Court for the District of Columbia In re Fannie Mae/Freddie Mac Senior Preferred Stock Purchase Agreement Class Action Litigations. This is a consolidated class action lawsuit filed by private individual and institutional investors (collectively, "Class Plaintiffs") against FHFA, Fannie Mae, and Freddie Mac. Fairholme Funds, Inc., et al. v. FHFA, et al. This is an individual plaintiffs’ lawsuit by certain institutional investors (“Individual Plaintiffs”) against FHFA, Fannie Mae, and Freddie Mac. Plaintiffs in each of the District of Columbia lawsuits filed an amended complaint on November 1, 2017 alleging claims for breach of contract, breach of the implied covenant of good faith and fair dealing, breach of fiduciary duties, and violation of Delaware and Virginia corporate law. Additionally, the Class Plaintiffs brought derivative claims against FHFA for breach of fiduciary duties and the Individual Plaintiffs brought claims under the Administrative Procedure Act. Both sets of claims are generally based on allegations that the net worth sweep dividend provisions of the senior preferred stock that were implemented pursuant to the August 2012 amendments nullified certain of the shareholders’ rights, including the rights to receive dividends and a liquidation preference. On September 28, 2018, the District Court dismissed all of the claims except those for breach of the implied covenant of good faith and fair dealing. The cases were consolidated for trial. Court rulings have limited the Plaintiffs’ damages theories to those based on the decline in Freddie Mac’s and Fannie Mae’s share value immediately after the Third Amendment. The Plaintiffs have asserted losses based on the decline in value of Freddie Mac’s common and junior preferred stock from August 16 to August 17, 2012. During the trial in October and early November 2022, the Plaintiffs requested that the jury award $832 million plus pre-judgment interest as damages against Freddie Mac. The jury in that trial was not able to reach a unanimous verdict and on November 7, 2022 the judge declared a mistrial. The retrial started on July 24, 2023. On August 14, 2023, the jury returned a verdict against FHFA, Fannie Mae, and Freddie Mac awarding compensatory damages of $282 million to Freddie Mac junior preferred shareholders and $31 million to Freddie Mac common shareholders. The jury declined to award the Freddie Mac shareholders prejudgment interest. In 3Q 2023, we recorded a $313 million accrual in other expense on our condensed consolidated statements of income for the adverse judgment. The entry of final judgment remains before the court.

Compliance with Regulatory Capital Requirements - ERCF [Abstract]
REGULATORY CAPITAL	ERCF The GSE Act specifies certain capital requirements for us and authorizes FHFA to establish other capital requirements as well as to increase our minimum capital levels or to establish additional capital and reserve requirements for particular purposes. In October 2008, FHFA suspended capital classification of us during conservatorship, in light of the Purchase Agreement. FHFA established the ERCF as a new enterprise regulatory capital framework for Freddie Mac and Fannie Mae in December 2020. Our current capital levels are significantly below the levels that would be required under the ERCF. The ERCF has a transition period for compliance, and we are not required to comply with the regulatory capital requirements or the buffer requirements while in conservatorship. In general, the compliance date for the regulatory capital requirements will be the later of the date of termination of our conservatorship and any later compliance date provided in a transition order, and the compliance date for buffer requirements in the ERCF will be the date of termination of our conservatorship. With respect to the ERCF's advanced approaches requirements, the compliance date is January 1, 2028 or any later compliance date specified by FHFA. The ERCF establishes risk-based and leverage capital requirements and includes capital requirements relating to the amount and form of the capital we hold, based largely on definitions of capital used in U.S. banking regulators' regulatory capital framework. The ERCF capital requirements contain both statutory capital elements (total capital and core capital) and regulatory capital elements (CET1 capital, Tier 1 capital, and adjusted total capital). The ERCF also includes a requirement that we hold prescribed capital buffers that can be drawn down in periods of financial stress and then rebuilt over time as economic conditions improve. If we fall below the prescribed buffer amounts, we must restrict capital distributions such as stock repurchases and dividends, as well as discretionary bonus payments to executives, until the buffer amounts are restored. Risk-Based Capital Requirements Under the ERCF risk-based capital requirements, we must maintain our CET1 capital, Tier 1 capital, and adjusted total capital ratios equal to at least 4.5%, 6.0%, and 8.0%, respectively, of RWA. We must also maintain statutory total capital equivalent to at least 8.0% of the total RWA. To avoid limitations on capital distributions and discretionary bonus payments tied to executive compensation, we also must maintain CET1 capital that exceeds the risk-based capital requirements by at least the amount of the PCCBA. The PCCBA consists of three separate component buffers—a stress capital buffer, a stability capital buffer, and a countercyclical capital buffer. n The stress capital buffer must be at least 0.75% of our ATA as of the last day of the previous calendar quarter. FHFA will periodically re-size the stress capital buffer to the extent that FHFA’s eventual program for supervisory stress tests determines that our peak capital exhaustion under a severely adverse stress scenario would exceed 0.75% of ATA. n The stability capital buffer is tailored to the risk that our default or other financial distress could pose to the liquidity, efficiency, competitiveness, or resiliency of national housing finance markets. The stability capital buffer is based on our share of residential mortgage debt outstanding. As of December 31, 2023, our stability capital buffer was 0.60% of ATA. n The countercyclical capital buffer is currently set at 0.0% of our ATA. FHFA has indicated that it will adjust the countercyclical capital buffer taking into account the macro-financial environment in which we operate, such that the buffer would be deployed only when excess aggregate credit growth is judged to be associated with a build-up of system-wide risk. Leverage Capital Requirements Under the ERCF leverage capital requirements, we must maintain our Tier 1 capital ratio equal to at least 2.5% of ATA. We must also maintain our statutory core capital ratio equal to at least 2.5% of ATA. To avoid limitations on capital distributions and discretionary bonus payments tied to executive compensation, we also must maintain Tier 1 capital that exceeds the leverage capital requirements by at least the amount of the PLBA. The PLBA is equal to 50% of our stability capital buffer. Capital Metrics The table below presents our capital metrics under the ERCF.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with GAAP and include our accounts as well as the accounts of other entities in which we have a controlling financial interest. All intercompany balances and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of our consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Management has made significant estimates to report the allowance for credit losses on single-family mortgage loans. Actual results could be different from these estimates.
Consolidation and Equity Method of Accounting	Consolidation and Equity Method Accounting For each entity with which we are involved, we determine whether the entity should be consolidated in our financial statements. We consolidate entities in which we have a controlling financial interest. The method for determining whether a controlling financial interest exists varies depending on whether the entity is a VIE. For entities that are not VIEs, we hold a controlling financial interest in entities where we hold a majority of the voting rights or a majority of a limited partnership's kick-out rights through voting interests. We do not currently consolidate any entities which are not VIEs. We use the equity method to account for our interests in entities in which we do not have a controlling financial interest, but over which we have significant influence.
Cash and Cash Equivalents	Cash and Cash Equivalents
Restricted Cash and Cash Equivalents	Cash collateral accepted from counterparties that we do not have the right to use for general corporate purposes is classified as restricted cash and cash equivalents on our consolidated balance sheets. Restricted cash and cash equivalents includes cash remittances received from servicers of the underlying assets of our consolidated trusts which are deposited into a separate custodial account. We invest the cash held in the custodial account in short-term investments; and we are entitled to the interest income earned on these short-term investments, which is recorded as interest income on our consolidated statements of income.

Consolidation, Variable Interest Entity, Policy	Securitizations and Variable Interest Entities Our primary business activities in the Single-Family and Multifamily segments involve the securitization of loans or other mortgage-related assets using trusts that are VIEs. These trusts issue beneficial interests in the loans or other mortgage-related assets that they own. We guarantee the principal and interest payments on some or all of the issued beneficial interests in substantially all of our securitization transactions. We also use trusts that are VIEs in certain CRT products. Consolidated VIEs We consolidate VIEs when we have a controlling financial interest in the VIE and are therefore considered the primary beneficiary of the VIE. We are the primary beneficiary of a VIE when we have both the power to direct the activities of the VIE that most significantly impact its economic performance and exposure to losses or benefits of the VIE that could potentially be significant to the VIE. We evaluate whether we are the primary beneficiary of VIEs in which we have interests at both inception and on an ongoing basis, and the primary beneficiary determination may change over time as our interest in the VIE changes. Generally, the assets of our consolidated VIEs can be used only to settle obligations of the VIE, and the creditors of our consolidated VIEs have recourse to the general credit of Freddie Mac only to the extent that we have provided a guarantee to the VIE. When we consolidate a VIE, we recognize the assets and liabilities of the VIE on our consolidated balance sheets and account for those assets and liabilities based on the applicable GAAP for each specific type of asset or liability. Assets and liabilities that we transfer to a VIE at, after, or shortly before the date we become the primary beneficiary of the VIE are initially measured at the same amounts that they would have been measured if they had not been transferred, and no gain or loss is recognized on these transfers. For all other VIEs that we consolidate, we recognize the assets and liabilities of the VIE at fair value, and we recognize a gain or loss for the difference between: n The sum of the fair value of the consideration paid, the fair value of any noncontrolling interests, and the reported amount of any previously held interests and n The fair value of the net identifiable assets recognized. Single-Family Securitization Products Level 1 Securitization Products Level 1 Securitization Products consist of UMBS, 55-day MBS, ARM and Gold PCs, which are all pass-through debt securities that represent undivided beneficial interests in a pool of loans held by a securitization trust. All Level 1 Securitization Products are backed only by mortgage loans we have acquired. We serve as both administrator and guarantor for these trusts. As administrator, we have the right to establish servicing terms and direct loss mitigation activities for the loans held by these trusts. As guarantor, we guarantee the payment of principal and interest on these securities in exchange for a guarantee fee, and we have the right to purchase delinquent loans from the trust to help improve the economic performance of the trust. We absorb all credit losses of these trusts through our guarantee of the principal and interest payments. The economic performance of these trusts is most significantly affected by the performance of the underlying loans. Our rights as administrator and guarantor provide us with the power to direct the activities that most significantly affect the performance of the underlying loans. We also have the obligation to absorb losses of these trusts that could potentially be significant through our guarantee of principal and interest payments. Accordingly, we concluded that we are the primary beneficiary of and, therefore, consolidate these trusts. Other Securitization Products Multifamily Securitization Products Multifamily PCs Multifamily PCs are fully guaranteed pass-through securities with a 55-day payment delay that are collateralized by a single underlying mortgage loan held by a securitization trust. We serve as both administrator and guarantor for these trusts. As administrator, we have the right to establish servicing terms and direct loss mitigation activities for the loans held by these trusts. As guarantor, we guarantee the payment of principal and interest on these securities in exchange for a guarantee fee, and we have the right to purchase a delinquent loan from the trust. We absorb all credit losses of these trusts through our guarantee of the principal and interest payments. The economic performance of these trusts is most significantly affected by the performance of the underlying loans. Our rights as administrator and guarantor provide us with the power to direct the activities that most significantly affect the performance of the underlying loans. We also have the obligation to absorb losses of these trusts that could potentially be significant through our guarantee of principal and interest payments. Accordingly, we concluded that we are the primary beneficiary of and, therefore, consolidate these trusts. K Certificates and Other Securitization Products We are the primary beneficiary of and, therefore, consolidate the trusts used to issue fully-guaranteed K Certificates and certain of our Multifamily other securitization products when we have the ability to direct the activities that most significantly affect the economic performance of the VIEs and we have the obligation to absorb credit losses through our guarantee of the issued securities. WI K-Deal Certificates In a WI K-Deal Certificate transaction, we forward sell a K Certificate that will be issued in the future to a WI K-Deal trust at a fixed price, thereby reducing our exposure to future changes in interest rates and K Certificate spreads. The WI K-Deal trust simultaneously issues guaranteed securities (WI Certificates). The economic performance of our WI K-Deal trusts is most significantly affected by the performance of the underlying assets. We manage the underlying assets of the trust prior to the delivery of the K Certificate and determine which K Certificate will be delivered into the trust. Therefore, we have the power to direct the activities that are most significant to the WI K-Deal trust. We also initially have economic exposure to the variability of the trust through our guarantee of the issued WI Certificates. As a result, we are the primary beneficiary of and, therefore, initially consolidate the trusts used to issue WI Certificates. Upon delivering the K Certificate into the trust, we no longer have a variable interest and therefore deconsolidate the WI K-Deal trust. Nonconsolidated VIEs Single-Family Securitization Products We do not consolidate certain of our Single-Family other securitization products, including senior subordinate securitizations backed by seasoned loans, because we do not have the ability to direct the loss mitigation activities of the underlying loans, which is the most significant activity affecting the economic performance of the VIE. When we sell loans in this type of transaction, we derecognize the transferred loans and account for our guarantee to the nonconsolidated VIE. We account for our investments in the beneficial interests issued by the nonconsolidated VIE, if any, as investments in debt securities. We also do not consolidate the trusts used to issue certain other types of our Single-Family other securitization products when we do not have the ability to direct the activities that most significantly affect the economic performance of the VIE. Resecuritization Products We create resecuritization products primarily by using Level 1 Securitization Products, our previously issued resecuritization products, or similar TBA-eligible products issued and guaranteed by Fannie Mae as the underlying collateral. In a typical resecuritization transaction, previously issued Level 1 Securitization Products or resecuritization products are transferred to a resecuritization trust that issues beneficial interests in the underlying collateral. We establish parameters that define eligibility standards for assets that may be used as collateral for each of our resecuritization programs. Resecuritization products can then be created based on the parameters that we have established. Similar to our Level 1 Securitization Products, we guarantee the full payment of principal and interest to the investors in our resecuritization products. The main types of resecuritization products we create are single-class resecuritization products (Supers, Giant MBS, and Giant PCs) and multiclass resecuritization products (REMICs and Strips). n Single-class resecuritization products - These securities are direct pass-throughs of the cash flows of the underlying collateral, which may be previously issued Level 1 Securitization Products, single-class resecuritization products, or similar TBA-eligible products issued and guaranteed by Fannie Mae. We do not consolidate the trusts used in these transactions unless we have the unilateral ability to liquidate the trust (for example if we own all of the trust's issued beneficial interests), as these transactions do not result in any new or incremental risk to the holders of the securities issued by the resecuritization trust and because we are not exposed to any incremental rights to receive benefits or obligations to absorb losses that could be significant to the resecuritization trust. We account for purchases of single-class resecuritization products that we issue that are substantially the same as the underlying collateral as debt extinguishment of a pro-rata portion of the underlying Level 1 Securitization Product. We account for purchases of single-class resecuritization products that we issue that are not considered substantially the same as the underlying collateral as investments in debt securities. Single-class resecuritization products that we issue that are backed entirely by Freddie Mac collateral are considered substantially the same as the underlying collateral, while commingled single-class resecuritization products that we issue are not considered substantially the same as the underlying collateral. n Multiclass resecuritization products - These securities are multiclass resecuritizations of the cash flows of the underlying collateral, which may be previously issued Level 1 Securitization Products, single-class resecuritization products, multiclass resecuritization products, or similar TBA-eligible products issued and guaranteed by Fannie Mae. The activity that most significantly impacts the economic performance of our multiclass resecuritization trusts is typically the initial design and structuring of the trust. Substantially all multiclass resecuritization trusts are created as part of transactions in which an investor or dealer participates in the decisions made during the design and establishment of the trust. As a result, we do not have the unilateral ability to direct the activities of our multiclass resecuritization trusts that most significantly impact the economic performance of those trusts. In addition, unless we retain a portion of the issued multiclass resecuritization products, we do not have the right to receive benefits or the obligation to absorb losses that could potentially be significant to the trusts because we have already provided a guarantee on the underlying assets. As a result, we have concluded that we are not the primary beneficiary of our multiclass resecuritization trusts and, therefore, do not consolidate those trusts unless we have the unilateral ability to liquidate the trust. When we purchase a multiclass resecuritization product as an investment in our mortgage-related investments portfolio, we record the security as an investment in debt securities rather than extinguishment of debt since we are investing in the debt securities of a nonconsolidated entity. Similarly, sales of multiclass resecuritization products previously held as investments in our mortgage-related investments portfolio are accounted for as sales of investments in debt securities. See Note 7 for additional information on accounting for investments in debt securities. CRT Products We transfer credit risk exposure on certain mortgage loans that we own or guarantee using CRT products, including STACR Trust notes. In STACR Trust notes transactions, a trust issues credit-linked notes whose repayments are based on the credit performance of a reference pool of mortgage loans. The trust uses the proceeds from the issuance of the notes to purchase short-term eligible investments and makes periodic payments of principal and interest on the notes to investors. We make payments to the trust to support payment of the interest due on the notes, and we receive payments from the trust that otherwise would have been made to the noteholders to the extent there are credit events on the mortgages in the reference pool. The note balances are reduced by the amount of the payments to us. The trust was designed to create and pass along to its interest holders the variability related to the credit risk of the mortgages in the reference pool. We do not have a variable interest in the risk that the trust was designed to create and pass along to its interest holders or the power to direct the activities that most significantly affect the economic performance of the VIE. As a result, we do not consolidate the trusts used in the STACR Trust note transactions. We account for our obligations to make certain payments to the STACR Trust note VIEs to support payment of the interest due on the notes as derivative instruments. We account for our rights to receive payments from the STACR Trust note VIEs to the extent there are credit events on the mortgages in the reference pool as freestanding credit enhancement contracts. Freestanding contracts are entered into separately and apart from any other financial instrument or in conjunction with some other transaction and are legally detachable and separately exercisable. We recognize the payments we make to transfer credit risk under freestanding credit enhancements, which primarily consist of STACR Trust notes and ACIS transactions in Single-Family, in credit enhancement expense in our consolidated statements of income when they are incurred. We recognize expected recoveries from such transactions in other assets with an offsetting reduction to non-interest expense, at the same time that we recognize an allowance for credit losses on the covered loans, measured on the same basis as the allowance for credit losses on the covered loans. Credit enhancements that are not freestanding contracts are considered when measuring our allowance for credit losses. See Note 6 for additional information on credit enhancements that are not freestanding contracts. Multifamily Securitization Products K Certificates In a typical K Certificate transaction, we sell multifamily loans to a non-Freddie Mac trust that issues senior and subordinate securities, and simultaneously purchase and place the senior securities into a Freddie Mac trust that issues guaranteed K Certificates. In these transactions, we guarantee the senior securities issued by the non-Freddie Mac trust but do not issue or guarantee the subordinate securities. We receive a guarantee fee in exchange for our guarantee. In certain of our K Certificate securitizations, we may also serve as master servicer. However, in contrast to most single-family transactions, the rights to direct loss mitigation activities of the underlying loans and to purchase delinquent loans from the securitization trust are generally held by the investor in the most subordinate remaining securities issued by the non-Freddie Mac trust, and therefore we do not have the power to direct those activities unless we are the investor in the most subordinate remaining securities. We do not typically invest in the subordinate securities issued in our K Certificate transactions. The economic performance of our K Certificate trusts is most significantly affected by the performance of the underlying loans. We do not consolidate our K Certificate securitization trusts that have subordination because we do not have the ability to direct the loss mitigation activities of the underlying loans, which is the most significant activity affecting the economic performance of the VIE. When we sell loans in a K Certificate transaction, we derecognize the transferred loans and account for our guarantee to the nonconsolidated VIE. We account for our investments in the beneficial interests issued by the trusts used in our K Certificate transactions as investments in debt securities. Other Securitization Products We do not consolidate the trusts used to issue our other securitization products when we do not have the ability to direct the activities that most significantly affect the economic performance of the VIE. For those products, we account for our guarantee to the nonconsolidated VIE. We account for our investments in the beneficial interests issued by the trusts used in our other securitization products as investments in debt securities. CRT Products In Multifamily, we may transfer credit risk on certain mortgage loans that we own or guarantee by entering into SCR Trust note transactions, which are similar to STACR Trust note transactions in Single-Family. We do not consolidate the trusts used in SCR Trust note transactions and account for SCR Trust note transactions in the same manner as we account for STACR Trust note transactions.
Transfers and Servicing of Financial Assets, Policy	Loans held by these trusts are recognized on our consolidated balance sheets as mortgage loans held-for-investment. The corresponding securities held by third parties are recognized on our consolidated balance sheets as debt. We extinguish the outstanding debt of the related consolidated trust and recognize gains or losses on debt extinguishment for the difference between the consideration paid and the debt carrying value when we purchase these securities as investments in our mortgage-related investments portfolio. Sales of these securities that were previously held as investments in our mortgage-related investments portfolio are accounted for as debt issuances.
Revenue from Contract with Customer	With the exception of commingled securities, our investments in, and guarantees of, securities issued by resecuritization trusts do not create any incremental exposure to loss because we already guarantee the underlying collateral. As a result, we do not receive any incremental guarantee fees in exchange for our guarantee, and, accordingly, we do not recognize any additional guarantee assets, guarantee obligations, or reserves for guarantee losses related to resecuritization trusts. In a typical multiclass resecuritization, we receive a one-time transaction fee which represents compensation for both the structuring and creation of the securities and for our ongoing administrative responsibilities to service the securities. We recognize the portion of the transaction fee related to creation of the securities immediately in earnings. We defer the portion of the fee related to ongoing administrative responsibilities and amortize it over the life of the associated trust. When we issue commingled resecuritization products, our guarantee of the Fannie Mae securities used as collateral creates incremental exposure to loss because our guarantee covers timely payment of principal and interest on such products from underlying Fannie Mae securities. If Fannie Mae were to fail to make a payment on a Fannie Mae security that we resecuritized, we would be responsible for making the payment. However, we view the likelihood of being required to perform on our guarantee of Fannie Mae securities as remote due to Fannie Mae’s status as a GSE and the funding commitment available to it through its senior preferred stock purchase agreement with Treasury. We did not charge an incremental fee for commingled securities issued prior to July 1, 2022; however, effective July 1, 2022, we began to charge a fee for any commingled security issued after that date.
Mortgage Loans	We own both single-family loans, which are secured by one- to four-unit residential properties, and multifamily loans, which are secured by properties with five or more residential rental units. Our single-family loans are predominantly first lien, fixed-rate loans secured by the borrower's primary residence. We do not typically acquire loans that have experienced more-than-insignificant deterioration in credit quality since origination as of our acquisition date, although we may acquire such loans in connection with certain of our securitization activities or other mortgage-related guarantees. Upon acquisition, we classify a loan as either held-for-investment or held-for-sale. Loans that we have the ability and intent to hold for the foreseeable future, including loans held by consolidated trusts and loans we intend to securitize using an entity we will consolidate, are classified as held-for-investment. Loans that we intend to sell are classified as held-for-sale. Held-for-investment loans for which we have not elected the fair value option are reported on our consolidated balance sheets at their amortized cost basis, net of the allowance for credit losses. The amortized cost basis is based on a loan's outstanding UPB, net of deferred fees and other cost basis adjustments (including unamortized premiums and discounts, fees we receive or pay when we acquire loans, commitment-related derivative basis adjustments, hedge accounting-related basis adjustments, and other pricing adjustments), excluding accrued interest receivable. Accrued interest receivable for both held-for-investment and held-for-sale loans is separately presented on our consolidated balance sheets and excluded for the purposes of disclosure of the amortized cost basis of mortgage loans held-for-investment. Held-for-sale loans for which we have not elected the fair value option are reported at lower-of-cost-or-fair-value determined on an individual loan basis on our consolidated balance sheets. Any excess of a held-for-sale loan's cost over its fair value is recognized as a valuation allowance in investment gains, net on our consolidated statements of income, with subsequent changes in this valuation allowance also being recorded in investment gains, net. Premiums, discounts, and other cost basis adjustments (including lower-of-cost-or-fair-value adjustments) are deferred and not amortized. We elect the fair value option for certain multifamily loans. Loans for which we have elected the fair value option are measured at fair value on a recurring basis, with subsequent gains or losses related to changes in fair value reported in investment gains, net on our consolidated statements of income. All fees, upfront costs, and other cost basis adjustments are recognized in earnings as incurred. Cash flows related to loans originally classified as held-for-investment are classified as either investing activities (e.g., principal repayments) or operating activities (e.g., interest payments received from borrowers included within net income) on our consolidated statements of cash flows. Cash flows related to loans originally classified as held-for-sale are classified as operating activities on our consolidated statements of cash flows.
Allowance for Loan Losses Policy	Allowance for Credit Losses For financial assets measured at amortized cost, we recognize an allowance for credit losses that is deducted from or added to the amortized cost basis of the financial asset to present the net amount expected to be collected on the financial asset on the balance sheet. In 1Q 2022, we adopted accounting guidance that eliminates the recognition and measurement of TDRs. Upon adoption of this guidance, we no longer incorporate the expected credit losses for TDRs we reasonably expect will occur in our estimation of the allowance for credit losses. See Note 4 for additional information on the adoption of the new accounting guidance. Allowance for Credit Losses Methodology We recognize changes in the allowance for credit losses through provision or benefit for credit losses on our consolidated statements of income. Mortgage Loans Held-for-Investment Our allowance for credit losses on mortgage loans pertains to single-family and multifamily loans classified as held-for-investment for which we have not elected the fair value option. We measure the allowance for credit losses on a pooled basis when our loans share similar risk characteristics. We record charge-offs in the period in which a loan is deemed uncollectible. Proceeds received in excess of amounts previously written off are recorded as a decrease to non-interest expense on our consolidated statements of income. Single-Family We estimate the allowance for credit losses for single-family loans on a pooled basis using a discounted cash flow model that evaluates a variety of factors to estimate the cash flows we expect to collect. If we determine that foreclosure on the underlying collateral is probable, we measure the allowance for credit losses for single-family loans based upon the fair value of the collateral, less costs to sell, adjusted for estimated proceeds from credit enhancements that are not freestanding contracts. The discounted cash flow model we use to estimate the single-family loan allowance for credit losses forecasts cash flows over the loan’s remaining contractual term, adjusted for expectations of prepayments. As a result, we do not revert to historical loss information for single-family loans. Cash flow estimates are discounted at the loan’s prepayment-adjusted effective interest rate, which is adjusted for projections in the underlying benchmark interest rate for adjustable-rate loans. We project cash flows we expect to collect using our historical experience, such as historical default rates and severity of loss, based on loan characteristics, such as current LTV ratios, delinquency status, geography, and borrowers' credit scores. These cash flow estimates are adjusted for current and forecasted economic conditions, such as current and forecasted interest rates and house price growth rates, and estimated recoveries from loss mitigation activities, credit enhancements that are not freestanding contracts, and disposition of collateral, less estimated disposition costs. Our estimate of expected credit losses is sensitive to changes in forecasted house price growth rates, which affect both the probability of default and severity of expected credit losses, and changes in forecasted interest rates, as declining (increasing) interest rates typically result in higher (lower) expected prepayments and a shorter (longer) estimated loan life, and therefore lower (higher) expected credit losses. Our forecast of house price growth rates leverages an internally based model and uses a nationwide house price growth forecast for the next three years. A Monte Carlo simulation generates many possible house price scenarios for up to 40 years for each MSA. These scenarios are used to estimate loan-level expected future cash flows and credit losses based on each loan’s individual characteristics. Our forecast of interest rates incorporates various interest rate scenarios over the remaining contractual life of the loan based on current interest rates and implied market volatilities. These projections require significant management judgment. We rely on third parties to provide certain model inputs used in our projections. At loan delivery, the seller provides us with loan data, which includes borrower and loan characteristics and underwriting information. Each subsequent month, the servicers provide us with monthly loan-level servicing data, including delinquency and loss information. We review the outputs of our model by considering qualitative factors such as current economic events and other external factors to determine whether the model outputs are consistent with our expectations. Further management adjustments may be necessary to take into consideration the qualitative factors that have occurred but that are not yet reflected in the factors used to derive the model outputs or the uncertainty inherent in our projections. Significant judgment is exercised in making these adjustments. Credit enhancements that are not freestanding contracts are obtained contemporaneously with, and in contemplation of, the origination of a financial instrument, and effectively travel with the financial instrument upon sale. Credit enhancements that are not freestanding contracts include primary mortgage insurance, which provides us with loan-level protection up to a specified percentage. Expected recoveries from credit enhancements that are not freestanding contracts are considered in determining the allowance for loan losses as discussed above, resulting in a reduction in the recognized provision for credit losses by the amount of the expected recoveries. Subsequent to foreclosure and charge-off of the allowance for credit losses, we reclassify expected recoveries from credit enhancements that were not freestanding contracts and were previously offset against the allowance for credit losses as separate receivables. We do not consider potential recoveries from freestanding credit enhancement contracts when measuring our allowance for credit losses. Multifamily We estimate the allowance for credit losses for multifamily loans using a loss-rate method to estimate the net amount of cash flows we expect to collect. The loss-rate method is based on a probability of default and loss given default framework that estimates credit losses by considering a loan’s underlying characteristics and current and forecasted economic conditions. Loan characteristics considered by our model include vintage, loan term, current DSCR, current LTV ratio, occupancy rate, and interest rate hedges. We generally forecast economic conditions over a reasonable and supportable two-year period prior to reverting to historical averages at the model input level over a five-year period, using a linear reversion method. We also consider as model inputs expected prepayments, contractually specified extensions, expected recoveries from collateral posting requirements, and the expected recoveries from credit enhancements that are not freestanding contracts. Our loss rates incorporate published historical commercial loan performance data, which we calibrate for differences between that data and our portfolio experience. Except for cases of fraud and certain other types of borrower defaults, most multifamily loans are nonrecourse to the borrower. As a result, the cash flows of the underlying property (including any credit enhancements that are not freestanding contracts) serve as the primary source of funds for repayment of the loan. For loans where we determined that the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the operation or sale of the collateral, we measure the allowance for credit losses using the fair value of the underlying collateral, less estimated costs to sell, adjusted for estimated proceeds from credit enhancements that are not freestanding contracts. Factors considered by management in determining whether a borrower is experiencing financial difficulty include the borrower’s current payment status and an evaluation of the underlying property's operating performance as represented by its current DSCR, its available credit enhancements, the current LTV ratio, the management of the underlying property, and the property's geographic location. We review the outputs of our model considering qualitative factors such as current economic events and other external factors to determine whether the model outputs are consistent with our expectations. Further management adjustments may be necessary to take into consideration the qualitative factors that have occurred but that are not yet reflected in the factors used to derive the model outputs. Advances of Pre-foreclosure Costs We may incur expenses related to a mortgage loan subsequent to its original acquisition but prior to foreclosure (pre-foreclosure costs). These expenses are incurred generally to protect or preserve our interest or legal right in or to the property prior to foreclosure, such as property taxes or homeowner's insurance premiums owed by the borrower. Many of these expenses are advanced by the servicer and are reimbursable from the borrower. If the borrower ultimately defaults, we reimburse the servicer for the advances it has made. Upon advance by the servicer, we recognize a receivable for the amounts due from the borrower and a payable for amounts due to the servicer. We recognize an allowance for credit losses for amounts that we do not ultimately expect to collect from the borrower. Off-Balance Sheet Credit Exposures We recognize an allowance for credit losses on off-balance sheet credit exposures for our guarantees that are not measured at fair value and other off-balance sheet arrangements based on expected credit losses over the contractual period in which we are exposed to credit risk through a present contractual obligation to extend credit, unless that obligation is unconditionally cancellable by us. We include this allowance for credit losses on off-balance sheet credit exposures within other liabilities on our consolidated balance sheets, with changes recognized through provision or benefit for credit losses on our consolidated statements of income. Our methodologies for estimating the allowance for credit losses on off-balance sheet credit exposures for our Single-Family and Multifamily guarantees are generally consistent with our methodologies for estimating the allowance for credit losses for single-family mortgage loans and multifamily mortgage loans, respectively. We obtain credit enhancements for certain of our guarantees through the creation of unguaranteed subordinated securities issued by nonconsolidated securitization trusts that absorb first losses prior to us having to perform on our guarantee of the senior securities. We consider the effect of subordination and other credit enhancements that are not freestanding contracts when measuring the allowance for credit losses on off-balance sheet credit exposures and, as a result, recognize such an allowance only if expected credit losses exceed the remaining amount of subordination. For many of our guarantees, expected credit losses do not exceed the remaining amount of subordination. We have not recorded an allowance for credit losses on our guarantees of Fannie Mae securities due to the support provided to Fannie Mae by the U.S. government, the importance of Fannie Mae to the liquidity and stability of the U.S. housing market, and the long history of zero credit losses on Fannie Mae securities.
Non-Accrual Loans	Interest Income We recognize interest income on an accrual basis except when we believe the collection of principal and interest in full is not reasonably assured, which generally occurs when a loan is three monthly payments or more past due, at which point we place the loan on non-accrual status unless the loan is well secured and in the process of collection based upon an individual loan assessment. A loan is considered past due if a full payment of principal and interest is not received within one month of its due date. We charge off outstanding accrued interest receivable through interest income when loans are placed on non-accrual status and recognize interest income on a cash basis while a loan is on non-accrual status. Cost basis adjustments on held-for-investment loans are amortized into interest income over the contractual life of the loan using the effective interest method. No amortization is recognized during periods in which a loan is on non-accrual status. A non-accrual loan is returned to accrual status when the collectability of principal and interest in full is reasonably assured. For single-family loans, we generally determine that collectability is reasonably assured when the loan returns to current payment status. For multifamily loans, the collectability of principal and interest is considered reasonably assured based on an analysis of the factors specific to the loan being assessed. Upon a loan's return to accrual status, all previously reversed interest income is recognized and amortization of any basis adjustments into interest income is resumed.
Loan reclassifications charge off policy change	Reclassifications We reclassify loans from held-for-investment to held-for-sale depending on our intent and ability to hold the loan for the foreseeable future. Upon reclassification from held-for-investment to held-for-sale, we perform a collectability assessment. When we determine that a loan to be reclassified has experienced more-than-insignificant deterioration in credit quality since origination, the excess of the loan’s amortized cost basis over its fair value is written off against the allowance for credit losses prior to the reclassification. If the charge-off amount exceeds the existing allowance for credit losses amount, an additional provision for credit losses is recognized. Any remaining allowance for credit losses after the charge-off is reversed through provision for credit losses.
Loan Restructurings	Loan Restructurings In 1Q 2022, we adopted accounting guidance in ASU 2022-02 that eliminates the recognition and measurement of TDRs. Upon adoption of this guidance, we no longer measure an allowance for credit losses for TDRs we reasonably expect will occur, and we evaluate all loan restructurings according to the accounting guidance for loan refinancing and restructuring to determine whether the restructuring should be accounted for as a new loan or a continuation of the existing loan. We derecognize the existing loan and account for the restructured loan as a new loan if the effective yield on the restructured loan is at least equal to the effective yield for comparable loans with similar collection risks and the modifications to the original loan are more than minor. If a loan restructuring does not meet these conditions, we carryforward the existing loan’s amortized cost basis and account for the restructured loan as a continuation of the existing loan. Substantially all of our loan restructurings involving borrowers experiencing financial difficulty are accounted for as a continuation of the existing loan. The discounted cash flow model we use in measuring our Single-Family allowance for credit losses forecasts cash flows we expect to collect using our historical experience, including the effects of our loss mitigation activities involving borrowers experiencing financial difficulty. When we account for a loan restructuring as a continuation of the existing loan, we update the loan’s effective interest rate based on the restructured terms and recognize interest income prospectively using the new effective rate. We also update the prepayment-adjusted effective interest rate used to discount cash flows in measuring our allowance for credit losses to reflect the loan’s restructured terms. As a result, subsequent to our adoption of the accounting guidance that eliminates the recognition and measurement of TDRs, we no longer recognize an allowance for credit losses for the economic concession granted to a borrower for changes in the timing and amount of contractual cash flows when a loan is restructured. However, because we adopted such guidance prospectively, we continue to use the loan's prepayment-adjusted effective interest rate just prior to the restructuring, with no adjustments made to the effective interest rate for changes in the timing of expected cash flows subsequent to the restructuring, for loans that were restructured and accounted for as TDRs prior to our adoption of the guidance and that have not been subsequently modified after our adoption of the guidance. As a result, we continue to measure an allowance for credit losses for the economic concession granted to a borrower for changes in the timing and amount of contractual cash flows for such loans.
Guarantees, Indemnifications and Warranties Policies	Guarantees and Other Off-Balance Sheet Credit Exposures Our guarantee activities primarily consist of mortgage-related guarantees in which we agree to absorb the credit risk of mortgage loans or other mortgage-related assets. In exchange for providing this guarantee, we receive an upfront or ongoing guarantee fee that is designed to be commensurate with the risks assumed and that will, over the long-term, provide us with cash flows that are expected to exceed the credit-related and administrative expenses of the underlying financial instruments. The profitability of our guarantee activities may vary and will depend on a number of factors, including our guarantee fee and the actual credit performance of the underlying financial instruments that we have guaranteed. We do not separately recognize guarantees to consolidated VIEs as we have already recognized the assets and liabilities of those VIEs on our consolidated balance sheets. When we issue a guarantee to a nonconsolidated VIE or other third party that exposes us to incremental credit risk, we recognize both a guarantee obligation at fair value and the consideration we receive for providing the guarantee, which typically consists of a guarantee asset that represents the fair value of future guarantee fees. As a practical expedient, the measurement of the fair value of the guarantee obligation is set equal to the consideration we receive to provide the guarantee, and no gain or loss is recognized upon issuance of the guarantee. Subsequently, we recognize changes in the fair value of the guarantee asset in current period earnings and amortize the guarantee obligation into earnings as we are released from risk under the guarantee. We also recognize an allowance for expected credit losses over the contractual period in which we are exposed to credit risk. See Note 6 for additional information on our allowance for credit losses on financial guarantees and other off-balance sheet credit exposures.
Investments in Securities	We currently classify and account for our securities as either available-for-sale or trading. Securities classified as trading are reported at fair value with changes in fair value included in investment gains, net, in our consolidated statements of income. Securities classified as available-for-sale are reported at fair value with changes in fair value included in AOCI, net of taxes. See Note 16 for additional information on how we determine the fair value of securities. We generally record purchases and sales of non-mortgage-related securities on the trade date. We generally record purchases and sales of mortgage-related securities on the expected settlement date, with a corresponding derivative recorded on the trade date. We generally recognize interest income using the effective interest method, which considers the contractual terms of the security. Deferred items, including premiums, discounts, and other basis adjustments, are amortized into interest income over the contractual lives of the securities. We recognize interest income using the prospective effective interest method for securities that can contractually be prepaid or otherwise settled in such a way that we may not recover substantially all of our recorded investment. Under this method, we recognize as interest income, over the expected life of the securities, the excess of the cash flows expected to be collected over the securities' carrying value. We update our estimates of expected cash flows periodically and recognize changes in the calculated effective interest rate on a prospective basis. We classify the cash flows related to both available-for-sale and trading securities as investing activities because we hold these securities for investment purposes. In cases where the transfer of a security represents a secured borrowing, we classify the related cash flows as financing activities. Gains and losses on the sale of securities are included in investment gains, net, including those gains (losses) reclassified into earnings from AOCI. We use the specific identification method for determining the cost basis of a security in computing the gain or loss.
Debt Securities Issued	Our debt is reported at amortized cost, with the exception of certain debt for which we elected the fair value option. Deferred items, including premiums, discounts, issuance costs, and hedge accounting-related basis adjustments, are reported as a component of total debt. These items are amortized and reported through interest expense using the effective interest method over the contractual life of the related indebtedness. Amortization of premiums, discounts, and issuance costs begins at the time of debt issuance. Amortization of hedge accounting-related basis adjustments begins upon the discontinuation of the related hedge relationship. We elected the fair value option on debt that contains embedded derivatives and certain other debt issuances. Changes in the fair value of these debt obligations are recorded in investment gains, net, with any upfront costs and fees incurred or received in exchange for the issuance of the debt being recognized in earnings as incurred and not deferred. Related interest expense continues to be reported as interest expense based on the stated terms of the debt securities. For additional information on our election of the fair value option, see Note 16 . When we repurchase or call outstanding debt securities, we recognize the difference between the amount paid to redeem the debt security and the carrying value in earnings as a component of investment gains, net. Contemporaneous transfers of cash between us and a creditor in connection with the issuance of a new debt security and satisfaction of an existing debt security are accounted for as either an extinguishment or a modification of an existing debt security. If the debt securities have substantially different terms, the transaction is accounted for as an extinguishment of the existing debt security. The issuance of a new debt security is recorded at fair value, fees paid to the creditor are expensed as incurred, and fees paid to third parties are deferred and amortized into interest expense over the life of the new debt security using the effective interest method. If the terms of the existing debt security and the new debt security are not substantially different, the transaction is accounted for as a modification of the existing debt. Fees paid to the creditor are deferred and amortized into interest expense over the life of the modified debt security using the effective interest method and fees paid to third parties are expensed as incurred. We also engage in transactions whereby we enter into an agreement to sell and subsequently repurchase (or purchase and subsequently resell) agency securities. When these transactions involve securities issued by consolidated entities, they are treated as issuances and extinguishments of debt.
Derivatives	Derivatives are reported at their fair value on our consolidated balance sheets. Changes in fair value on derivatives not in qualifying fair value hedge relationships are recorded as investment gains, net, on our consolidated statements of income. Derivatives in a net asset position, including net derivative interest receivable or payable, are reported as derivative assets, net, which is included in other assets on our consolidated balance sheets. Similarly, derivatives in a net liability position, including net derivative interest receivable or payable, are reported as derivative liabilities, net, which is included in other liabilities on our consolidated balance sheets. We offset fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral against fair value amounts recognized for derivative instruments executed with the same counterparty under a master netting agreement. Non-cash collateral held is not recognized on our consolidated balance sheets as we do not obtain effective control over the collateral, and non-cash collateral posted is not derecognized from our consolidated balance sheets as we do not relinquish effective control over the collateral. Therefore, non-cash collateral held or posted is not presented as an offset against derivative assets or derivative liabilities on our consolidated balance sheets. See Note 10 for additional information on our collateralized arrangements. We evaluate whether financial instruments that we purchase or issue contain embedded derivatives. We generally elect to measure newly acquired or issued financial instruments that contain embedded derivatives at fair value, with changes in fair value recorded in earnings. On our consolidated statements of cash flows, cash flows related to derivatives are classified as either operating activities (such as periodic settlements of interest payments) or investing activities (such as variation margin payments and cash flows related to the acquisition and termination of derivatives) depending on the nature of the activity. Cash flows related to physical settlement of forward commitments accounted for as derivative instruments are classified as operating, investing, or financing activities depending on the financial instruments to which they relate.
Derivatives, Methods of Accounting, Hedging Derivatives	We apply fair value hedge accounting to certain single-family mortgage loans where we hedge the changes in fair value of these loans attributable to the designated benchmark interest rate, using interest-rate swaps. We also apply fair value hedge accounting to certain issuances of debt where we hedge the changes in fair value of the debt attributable to the designated benchmark interest rate, using interest-rate swaps. Under the portfolio layer method fair value hedge accounting strategy, we hedge the changes in fair value of a portion of a closed pool of single-family mortgage loans that is not expected to be affected by prepayments, defaults, and other events affecting the timing and amount of cash flows. As part of this strategy, we have also elected to measure the change in fair value of the hedged item on the basis of the benchmark rate component of the contractual coupon cash flows determined at the hedge inception and by assuming the hedged item has a term that reflects only the designated cash flows being hedged. We apply hedge accounting to qualifying hedge relationships. A qualifying hedge 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 hedge relationship. No amounts have been excluded from the assessment of hedge effectiveness. To assess hedge effectiveness, we use a statistical regression analysis. At inception of the hedge relationship, we prepare formal contemporaneous documentation of our risk management objective and strategies for undertaking the hedge. If a hedge relationship qualifies for fair value hedge accounting, all changes in fair value of the derivative hedging instrument, including interest accruals, are recognized in the same consolidated statements of income line item used to present the earnings effect of the hedged item. Therefore, changes in the fair value of the hedged item, mortgage loans and debt, attributable to the risk being hedged are recognized in interest income and interest expense, respectively, along with the changes in the fair value of the respective derivative hedging instruments. Changes in the fair value of the hedged item attributable to the risk being hedged are recognized as a cumulative basis adjustment against the mortgage loans and debt. The cumulative basis adjustments are amortized to the same consolidated statements of income line item used to present the changes in fair value of the hedged item using the effective interest method considering the contractual terms of the hedged item, with amortization beginning no later than the period in which hedge accounting was discontinued.
Derivatives, Offsetting Fair Value Amounts, Policy	We use master netting and collateral agreements to reduce our credit risk exposure to our OTC derivative counterparties for interest-rate swap and option-based derivatives. Master netting agreements provide for the netting of amounts receivable and payable from an individual counterparty, as well as posting of collateral in the form of cash, Treasury securities or agency mortgage-related or debt securities, or a combination of both by either the counterparty or us, depending on which party is in a liability position. Although it is our practice not to repledge assets held as collateral, these agreements may allow us or our counterparties to repledge all or a portion of the collateral. We have master netting agreements in place with all of our OTC derivative counterparties. On a daily basis, the market value of each counterparty's derivatives outstanding is calculated to determine the amount of our net credit exposure, which is equal to the market value of derivatives in a net gain position by counterparty after giving consideration to collateral posted. In the event a counterparty defaults on its obligations under the derivatives agreement and the default is not remedied in the manner prescribed in the agreement, we have the right under the agreement to sell the collateral. As a result, our use of master netting and collateral agreements reduces our exposure to our counterparties in the event of default.
Repurchase and Resale Agreements and Dollar Roll Transactions	Securities Purchased Under Agreements to Resell and Securities Sold Under Agreements to Repurchase As an investor, we enter into arrangements to purchase securities under agreements to subsequently resell the identical or substantially the same securities to our counterparty. Our counterparties to these transactions are required to pledge the purchased securities as collateral for their obligation to repurchase those securities at a later date. While such transactions involve the legal transfer of securities, they are accounted for as secured financings because the transferor does not relinquish effective control over the securities transferred. These agreements may allow us to repledge all, or a portion, of the collateral pledged to us, and we may repledge such collateral periodically, although it is not typically our practice to repledge collateral that has been pledged to us. We consider the types of securities being pledged to us as collateral when determining how much we lend in transactions involving securities purchased under agreements to resell. Additionally, we regularly review the market values of these securities compared to amounts loaned in an effort to manage our exposure to losses and we reasonably expect the borrower to continue to replenish the collateral to meet the requirements of the contract. As of December 31, 2023, all of our securities purchased under agreements to resell were fully collateralized. We utilize the GSD/FICC as a clearinghouse to transact many of our trades involving securities purchased under agreements to resell, securities sold under agreements to repurchase, and other non-mortgage related securities. As a clearing member of GSD/FICC, we are required to post initial and variation margin payments and are exposed to the counterparty credit risk of GSD/FICC (including its clearing members). In the event a clearing member fails and causes losses to the GSD/FICC clearing system, we could be subject to the loss of the margin that we have posted to the GSD/FICC. Moreover, our exposure could exceed that amount, as members are generally required to cover losses caused by defaulting members on a pro rata basis. It is difficult to estimate our maximum exposure under these transactions, as this would require an assessment of transactions that we and other members of the GSD/FICC may execute in the future. We provide financing to investors in Freddie Mac securities to increase liquidity and expand the investor base for those securities. These transactions differ from the securities purchased under agreements to resell that we use for liquidity purposes as the counterparties we face may not be major financial institutions and we are exposed to greater counterparty credit risk for these institutions. As of both December 31, 2023 and December 31, 2022, $1.1 billion of our securities purchased under agreements to resell were used to provide financing to investors in Freddie Mac securities. Securities sold under agreements to repurchase are effectively collateralized borrowings where we sell securities with an agreement to repurchase such securities at a future date. We are required to pledge the sold securities to the counterparties to these transactions as collateral for our obligation to repurchase these securities at a later date. Similar to the securities purchased under agreements to resell transactions, these transactions involve the legal transfer of securities. However, they are accounted for as secured financings because the transferor does not relinquish effective control over the securities transferred. These agreements may allow our counterparties to repledge all or a portion of the collateral.
Stockholders' Equity	Treasury, as the holder of the senior preferred stock, is entitled to receive quarterly cash dividends, when, as, and if declared by our Board of Directors. The dividends we have paid to Treasury on the senior preferred stock have been declared by, and paid at the direction of, the Conservator, acting as successor to the rights, titles, powers, and privileges of the Board of Directors. See Note 2 for additional information concerning our senior preferred stock dividends. We account for the warrant in permanent equity. At issuance on September 7, 2008, we recognized the warrant at fair value, and we do not recognize subsequent changes in fair value while the warrant remains classified in equity. We recorded an aggregate fair value of $2.3 billion for the warrant as a component of additional paid-in-capital. We derived the fair value of the warrant using a modified Black-Scholes model. If the warrant is exercised, the stated value of the common stock issued will be reclassified to common stock on our consolidated balance sheets. The warrant was determined to be in-substance non-voting common stock, because the warrant's exercise price of $0.00001 per share is considered non-substantive (compared to the market price of our common stock). As a result, the shares associated with the warrant are included in the computation of basic and diluted earnings per share. The weighted average shares of common stock for the years ended December 31, 2023, 2022, and 2021 included shares of common stock that would be issuable upon full exercise of the warrant issued to Treasury.
Stockholders' Equity Note, Redeemable Preferred Stock, Issue, Policy	No cash was received from Treasury under the Purchase Agreement in 2023 because we had positive net worth at December 31, 2022, March 31, 2023, June 30, 2023, and September 30, 2023 and, consequently, FHFA did not request a draw on our behalf in 2023. At December 31, 2023, our assets exceeded our liabilities under GAAP; therefore, no draw is being requested from Treasury under the Purchase Agreement. Common Stock Warrant Pursuant to the Purchase Agreement described in Note 2 , on September 7, 2008, we issued a warrant to purchase common stock to Treasury, in partial consideration of Treasury's commitment to provide funds to us. The warrant may be exercised in whole or in part at any time on or before September 7, 2028, by delivery to us of a notice of exercise, payment of the exercise price of $0.00001 per share, and the warrant. If the market price of one share of our common stock is greater than the exercise price, then, instead of paying the exercise price, Treasury may elect to receive shares equal to the value of the warrant (or portion thereof being canceled) pursuant to the formula specified in the warrant. Upon exercise of the warrant, Treasury may assign the right to receive the shares of common stock issuable upon exercise to any other person. We account for the warrant in permanent equity. At issuance on September 7, 2008, we recognized the warrant at fair value, and we do not recognize subsequent changes in fair value while the warrant remains classified in equity. We recorded an aggregate fair value of $2.3 billion for the warrant as a component of additional paid-in-capital. We derived the fair value of the warrant using a modified Black-Scholes model. If the warrant is exercised, the stated value of the common stock issued will be reclassified to common stock on our consolidated balance sheets. The warrant was determined to be in-substance non-voting common stock, because the warrant's exercise price of $0.00001 per share is considered non-substantive (compared to the market price of our common stock). As a result, the shares associated with the warrant are included in the computation of basic and diluted earnings per share. The weighted average shares of common stock for the years ended December 31, 2023, 2022, and 2021 included shares of common stock that would be issuable upon full exercise of the warrant issued to Treasury. Preferred Stock We have the option to redeem our preferred stock on specified dates, at their redemption price plus dividends accrued through the redemption date. However, without the consent of Treasury, we are restricted from making payments to purchase or redeem preferred stock as well as paying any preferred dividends, other than dividends on the senior preferred stock. All 24 classes of preferred stock are perpetual and non-cumulative, and carry no significant voting rights or rights to purchase additional Freddie Mac stock or securities. Costs incurred in connection with the issuance of preferred stock are charged to additional paid-in capital.
Earnings Per Common Share	Basic earnings per common share is computed as net income attributable to common stockholders divided by the weighted average common shares for the period. The weighted average common shares for the period includes the weighted average number of shares that are associated with the warrant for our common stock issued to Treasury pursuant to the Purchase Agreement. These shares are included since the warrant is unconditionally exercisable by the holder at a minimal cost. We deduct dividends or increases in liquidation preference attributable to the senior preferred stock from net income attributable to common stockholders in the period in which such amounts are determinable. Our diluted earnings per common share is the same as our basic earnings per common share because we had no common equivalent shares outstanding during the periods presented which could have had a dilutive or antidilutive effect.
Segment Reporting	Segment Description Single-Family Reflects results from our purchase, securitization, and guarantee of single-family loans, our investments in single-family loans and mortgage-related securities, the management of Single-Family mortgage credit risk and market risk, and any results of our treasury function that are not allocated to each segment. Multifamily Reflects results from our purchase, securitization, and guarantee of multifamily loans, our investments in multifamily loans and mortgage-related securities, and the management of Multifamily mortgage credit risk and market risk.
Fair Value Measurements	The accounting guidance for fair value measurements and disclosures defines fair value, establishes a framework for measuring fair value and sets forth disclosure requirements regarding fair value measurements. This guidance applies whenever other accounting guidance requires or permits assets or liabilities to be measured at fair value. Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement assumes that the transaction to sell the asset or transfer the liability takes place either in the principal market for the asset or liability, or, in the absence of a principal market, in the most advantageous market for the asset or liability. We use fair value measurements for the initial recording of certain assets and liabilities and periodic remeasurement of certain assets and liabilities on a recurring or non-recurring basis. Fair Value Measurements The accounting guidance for fair value measurements and disclosures establishes a three-level fair value hierarchy that prioritizes the inputs into the valuation techniques used to measure fair value. The levels of the fair value hierarchy are defined as follows in priority order: n Level 1 - Inputs to the valuation techniques are based on quoted prices in active markets for identical assets or liabilities. n Level 2 - Inputs to the valuation techniques are based on observable inputs other than quoted prices in active markets for identical assets or liabilities. n Level 3 - One or more inputs to the valuation technique are unobservable and significant to the fair value measurement. We use quoted market prices and valuation techniques that seek to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs. Our inputs are based on the assumptions a market participant would use in valuing the asset or liability. Assets and liabilities are classified in their entirety within the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.
Income Taxes	Income Tax Expense Total income tax expense includes: n Current income tax expense, which represents the amount of federal tax paid or payable to (or refundable from) the Internal Revenue Service, including interest and penalties and amounts accrued for unrecognized tax benefits, if any, and n Deferred income tax expense, which represents the net change in the deferred tax asset or liability balance during the year, including any change in the valuation allowance. Deferred Tax Assets, Net We use the asset and liability method of accounting for income taxes for financial reporting purposes. Under this method, deferred tax assets and liabilities are recognized based upon the expected future tax consequences of existing temporary differences between the financial reporting and the tax reporting basis of assets and liabilities using enacted statutory tax rates as well as tax net operating loss and tax credit carryforwards, if any. To the extent tax laws change, deferred tax assets and liabilities are adjusted in the period that the tax change is enacted. The realization of our net deferred tax assets is dependent upon the generation of sufficient taxable income.

Liabilities primarily include our guarantee obligations. (2) Total assets and maximum exposure to loss are based on the UPB of Fannie Mae securities underlying commingled Freddie Mac resecuritization trusts. We exclude noncommingled resecuritization trusts from these amounts as we have already guaranteed the underlying collateral and therefore noncommingled resecuritizations do not involve any incremental assets or create any incremental exposure to credit risk. Total assets exclude $0.1 billion as of both December 31, 2023 and December 31, 2022, of Fannie Mae securities that we have guaranteed that are included in resecuritization trusts that we have consolidated as we own all of the outstanding securities issued by the VIE. (3) Maximum exposure to loss is based on our expected recovery receivables and excludes our obligations to make certain payments to the VIE to support payment of the interest due on the notes issued by the VIE, which we account for as derivative instruments. The notional value of these derivative instruments is equal to the total assets of the VIE.

(2) Our sales of multifamily loans occur primarily through the issuance of Multifamily K Certificates. Reclassifications We reclassify loans from held-for-investment to held-for-sale depending on our intent and ability to hold the loan for the foreseeable future. Upon reclassification from held-for-investment to held-for-sale, we perform a collectability assessment. When we determine that a loan to be reclassified has experienced more-than-insignificant deterioration in credit quality since origination, the excess of the loan’s amortized cost basis over its fair value is written off against the allowance for credit losses prior to the reclassification. If the charge-off amount exceeds the existing allowance for credit losses amount, an additional provision for credit losses is recognized. Any remaining allowance for credit losses after the charge-off is reversed through provision for credit losses. We reclassify loans from held-for-sale to held-for-investment when we have both the intent and ability to hold the loan for the foreseeable future. Upon reclassification from held-for-sale to held-for-investment, we reverse the loan’s held-for-sale valuation allowance, if any, and establish an allowance for credit losses as needed. The table below presents the allowance for credit losses or valuation allowance that was reversed or established due to loan reclassifications between held-for-investment and held-for-sale during the periods presented.

Multifamily The table below presents the amortized cost basis of our multifamily held-for-investment loans, for which we have not elected the fair value option, by credit quality indicator, based on available data through the end of each period presented. These indicators involve significant management judgment and are defined as follows: n "Pass" is current and adequately protected by the borrower's current financial strength and debt service capacity; n "Special mention" has administrative issues that may affect future repayment prospects but does not have current credit weaknesses. In addition, this category generally includes loans in forbearance; n "Substandard" has a weakness that jeopardizes the timely full repayment; and n "Doubtful" has a weakness that makes collection or liquidation in full highly questionable and improbable based on existing conditions.

Table - Payment Status of Mortgage Loans	The table below presents the amortized cost basis of our single-family and multifamily held-for-investment loans, for which we have not elected the fair value option, by payment status. We report single-family loans in forbearance as past due during the forbearance period to the extent that payments are past due based on the loan's original contractual terms, irrespective of the forbearance plan, based on the information reported to us by our servicers. We report multifamily loans in forbearance as current as long as the borrower is in compliance with the forbearance agreement, including the agreed upon repayment plan, even if payments are past due based on the loan's original contractual terms.

(2) Loans with no allowance for loan losses primarily represent loans that were previously charged off and for which the amount we expect to collect is sufficiently in excess of the amortized cost to result in recovery of the entire amortized cost basis if the property were foreclosed upon or otherwise subject to disposition. We exclude the amounts of allowance for credit losses on accrued interest receivable and advances of pre-foreclosure costs when determining whether a loan has an allowance for credit losses.
Table - Loan Restructuring	For purposes of the disclosure related to single-family loan restructurings involving borrowers experiencing financial difficulty, we exclude loans that were held-for-sale either at the time of restructuring or at the period end. The table below presents the amortized cost basis of single-family held-for-investment loan restructurings involving borrowers experiencing financial difficulty that we entered into during the periods presented.

The table below shows the financial effect of single-family held-for-investment loan restructurings involving borrowers experiencing financial difficulty that we entered into during the periods presented.

The financial effects of forbearance plans and repayment plans consist of a payment delay of between one and twelve months. In addition, the financial effect of a forbearance plan is included at the time the forbearance plan is completed if the borrower exits forbearance by entering into a payment deferral plan or loan modification. (2) Primarily related to payment deferral plans. Amounts are based on non-interest-bearing principal balances on the restructured loans. The following table provides the amortized cost basis of single-family held-for-investment loans that had a payment default (i.e., loans that became two months delinquent) during the periods presented and had been restructured within the previous 12 months preceding the payment default, when the borrower was experiencing financial difficulty at the time of the restructuring. Since we adopted ASU 2022-02 prospectively, single-family held-for-investment loans that were restructured prior to January 1, 2022, the date we adopted such guidance, have been excluded from the disclosures related to loan restructurings.

The following table provides the single-family held-for-investment loan performance in the 12 months after a restructuring involving borrowers experiencing financial difficulty. While a single-family loan is in a forbearance plan or repayment plan, payments continue to be due based on the loan’s original contractual terms because the loan has not been permanently modified. As a result, we report single-family loans in forbearance plans and repayment plans as delinquent to the extent that payments are past due based on the loan’s original contractual terms. Loans that have been restructured by entering into a payment deferral plan or loan modification are reported as delinquent to the extent that payments are past due based on the loan's restructured terms.
