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. The conservatorship and related matters significantly affect our management, business activities, financial condition, and results of operations. In connection with our entry into conservatorship, we entered into the Purchase Agreement with Treasury, under which we issued Treasury both senior preferred stock and a warrant to purchase common stock. Our Purchase Agreement with Treasury is critical to keeping us solvent and avoiding the appointment of a receiver by FHFA under statutory mandatory receivership provisions. We believe the support provided by Treasury pursuant to the Purchase Agreement currently enables us to have adequate liquidity to conduct normal business activities. For more information on the conservatorship, the roles of FHFA and Treasury, and the Purchase Agreement, see our 2023 Annual Report. Throughout our unaudited condensed consolidated financial statements and related notes, we use certain acronyms and terms which are defined in the Glossary of our 2023 Annual Report. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in our 2023 Annual Report. Basis of Presentation The accompanying unaudited condensed 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. In the opinion of management, our unaudited condensed consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary for a fair statement of our results. Use of Estimates The preparation of our condensed 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 at the date of the financial statements. 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 Investments 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. We invest in LIHTC partnerships to support and preserve the supply of affordable housing. We have elected to account for these investments using the proportional amortization method when applicable. The carrying amount of our investments in LIHTC partnerships is presented in other assets on our condensed consolidated balance sheets and totaled $3.6 billion as of March 31, 2024. Recently Issued Accounting Guidance Recently Adopted Accounting Guidance Standard Description Date of 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 The adoption of these amendments did not have a material effect on our consolidated financial statements. See the preceding section Consolidation and Equity Investments for further information. Recently Issued Accounting Guidance, Not Yet Adopted Within Our Consolidated Financial Statements Standard Description Date of Effect on Consolidated Financial Statements 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.

Securitization Activities and Consolidation	Securitizations and Variable Interest Entities Nonconsolidated VIEs The following table presents the carrying amounts and classification of the assets and liabilities recorded on our condensed 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 4 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.

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 less than $0.1 billion and $0.1 billion as of March 31, 2024 and December 31, 2023, respectively, 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.

As current LTV ratios increase, the borrower's equity in the home decreases, which may negatively affect the borrower's ability to refinance or to sell the property for an amount at or above the balance of the outstanding loan. The table below presents the amortized cost basis of single-family held-for-investment loans by current LTV ratio. Our current LTV ratios are estimates 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.

(1) There were no held-for-investment loans that were three months or more past due and accruing interest as of both March 31, 2024 and December 31, 2023. (2) Includes $2.0 billion of single-family loans that were in the process of foreclosure as of both March 31, 2024 and December 31, 2023. (3) 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 advances of pre-foreclosure costs when determining whether a loan has an allowance for credit losses. Loan Restructurings 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. 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 amortized cost basis of loans in trial period modification plans was $2.2 billion and $1.8 billion as of both March 31, 2024 and March 31, 2023, respectively. Most of these loans are 20- and 30-year or more, amortizing fixed-rate loans.

Also includes forbearance plans, repayment plans, and loan modifications that only involve payment delays. (3) Based on the amortized cost basis as of period end, divided by the total period-end amortized cost basis of the corresponding financing receivable class of single-family held-for-investment loans. 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.

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.

Guarantees [Abstract]
Guarantees and Other Off-Balance Sheet Credit Exposures	Guarantees and Other Off-Balance Sheet Credit Exposures Guarantee Activities 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 condensed 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 5 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 $0.7 billion and $0.3 billion as of March 31, 2024 and December 31, 2023, 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 March 31, 2024 and December 31, 2023. (4) Excludes less than $0.1 billion and $0.1 billion as of March 31, 2024 and December 31, 2023, respectively, 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.

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 5 for additional discussion of our allowance for credit losses on our off-balance sheet credit exposures.

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 apply fair value hedge accounting to certain single-family mortgage loans and certain issuances of debt where we hedge the changes in fair value of these items attributable to the designated benchmark interest rate, using interest-rate swaps. Derivative Assets and Liabilities at Fair Value The table below presents the notional value and fair value of derivatives reported on our condensed consolidated balance sheets.

(2) Represents the aggregate amount of Level 3 assets and liabilities measured at fair value on a recurring basis that are individually and in the aggregate insignificant. 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 measurement of impairment based on the fair value of the underlying collateral. Certain fair values in the tables below were not obtained as of period end, but were obtained during the period. The table below presents assets measured on our condensed 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, and certain debt, the carrying value on our condensed consolidated balance sheets approximates fair value, as these assets and liabilities are short-term in nature and have limited fair value volatility.

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 connection with any of these lawsuits or any future lawsuits. However, it is possible that we could be adversely affected by these actions, 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.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed 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 condensed 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 at the date of the financial statements. 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	Consolidation and Equity Investments 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.
Other Significant Accounting Policies	Recently Issued Accounting Guidance Recently Adopted Accounting Guidance Standard Description Date of 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 The adoption of these amendments did not have a material effect on our consolidated financial statements. See the preceding section Consolidation and Equity Investments for further information. Recently Issued Accounting Guidance, Not Yet Adopted Within Our Consolidated Financial Statements Standard Description Date of Effect on Consolidated Financial Statements 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Table - Schedule of Various Interest Entities	The following table presents the carrying amounts and classification of the assets and liabilities recorded on our condensed 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 4 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.

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 less than $0.1 billion and $0.1 billion as of March 31, 2024 and December 31, 2023, respectively, 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.

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.

(2) Includes $2.0 billion of single-family loans that were in the process of foreclosure as of both March 31, 2024 and December 31, 2023. (3) 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 advances of pre-foreclosure costs when determining whether a loan has an allowance for credit losses.
Table - Loan Restructuring	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 amortized cost basis of loans in trial period modification plans was $2.2 billion and $1.8 billion as of both March 31, 2024 and March 31, 2023, respectively. Most of these loans are 20- and 30-year or more, amortizing fixed-rate loans.

Also includes forbearance plans, repayment plans, and loan modifications that only involve payment delays. (3) Based on the amortized cost basis as of period end, divided by the total period-end amortized cost basis of the corresponding financing receivable class of single-family held-for-investment loans. 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.

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.
