Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Angel Oak Mortgage, Inc. (together with its subsidiaries the “Company”), is a real estate finance company focused on acquiring and investing in first lien non-qualified residential mortgage (“non-QM”) loans and other mortgage‑related assets in the U.S. mortgage market. The Company’s strategy is to make investments in first lien non‑QM loans that are primarily made to higher‑quality non‑QM loan borrowers and primarily sourced from the proprietary mortgage lending platform of affiliates, Angel Oak Mortgage Solutions LLC and Angel Oak Home Loans LLC (together, “Angel Oak Mortgage Lending”), which operates through wholesale and retail channels and has a national origination footprint. The Company may also invest in other residential mortgage loans, residential mortgage‑backed securities (“RMBS”), and other mortgage‑related assets. The Company’s objective is to generate attractive risk‑adjusted returns for its stockholders, through cash distributions and capital appreciation, across interest rate and credit cycles. The Company is a Maryland corporation incorporated on March 20, 2018. On September 18, 2018 (commencement of operations), the Board of Directors of the Company (the “Board of Directors”) authorized the Company to commence operations and on October 19, 2018 the Company began its investing activities. For the period prior to September 18, 2018, the Company had no operating activity. The Company achieves certain of its investment objectives by investing a portion of its assets in its wholly‑owned taxable subsidiary, Angel Oak Mortgage REIT TRS, LLC (“AOMR TRS”), a Delaware limited liability company formed on March 21, 2018, which invests its assets in Angel Oak Mortgage Fund TRS, a Delaware statutory trust formed on June 15, 2018. On June 21, 2021, the Company completed its initial public offering (the “IPO”) of 7,200,000 shares of common stock, $0.01 par value per share (“common stock”), at an initial public offering price of $19.00 per share for total proceeds of approximately $136.8 million, excluding the underwriting discounts and commissions and offering expenses of the IPO, each of which was paid by Angel Oak Capital Advisors, LLC (“Angel Oak Capital”), pursuant to a registration statement on Form S-11, as amended (File No. 333-256301) (the “Registration Statement”), filed with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended. The common stock of the Company trades on the New York Stock Exchange under the ticker symbol “AOMR”. Concurrently with the completion of the IPO, the Company sold an additional 2,105,263 shares of common stock to CPPIB Credit Investments Inc. in a private placement at $19.00 per share, for total proceeds of approximately $40.0 million. The Operating Partnership On February 5, 2020, the Company formed Angel Oak Mortgage Operating Partnership, LP, a Delaware limited partnership (the “Operating Partnership”), through which substantially all of its assets are held and substantially all of its operations are conducted, either directly or through subsidiaries. The Company holds all of the limited partnership interests in the Operating Partnership and indirectly holds the sole general partnership interest in the Operating Partnership through the general partner, which is the Company’s wholly-owned subsidiary. The Company’s Manager and REIT status The Company is externally managed and advised by Falcons I, LLC (the “Manager”), a registered investment adviser with the SEC. The Company has elected to be taxed as a real estate investment trust (a “REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its taxable year ended December 31, 2019 and will operate in conformity with the requirements for qualification as a REIT under the Code. Interim Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with the instructions to Article 10-01 of Regulation S-X for interim financial statements. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles in the United States of America (“GAAP”) for complete financial statements. These unaudited condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “Annual Report on Form 10-K”). In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. Such operating results may not be indicative of the expected results for any other interim periods or the entire year. The condensed consolidated financial statements include the accounts of the Company and its wholly‑owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements requires the Company to make a number of significant estimates. These include estimates of fair value of certain assets and liabilities, amounts and timing of credit losses, prepayment rates, and other estimates that affect the reported amounts of certain assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of certain revenues and expenses during the reported periods. It is likely that changes in these estimates (e.g., valuation changes due to supply and demand, credit performance, prepayments, interest rates, or other reasons) will occur in the near term. The Company’s estimates are inherently subjective in nature and actual results could differ from the Company’s estimates and the differences could be material. Reclassifications Certain amounts reported in prior periods in the financial statements have been reclassified to conform to the current year’s presentation. For comparative purposes, and to enhance transparency of the Company’s balance sheet, “other assets” on the condensed consolidated balance sheet as of December 31, 2021 in the amount of $2.4 million have been reclassified to unrealized appreciation on “To be Announced” forward-settling of mortgage-backed securities trades (“TBAs”) and interest rate futures contracts - at fair value, leaving a remaining balance of $2.9 million of other assets. Recent Accounting Standards - Recently Issued In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The standard was issued to ease the accounting effects of reform to the London Interbank Offered Rate (“LIBOR”) and other reference rates. The standard provides optional expedients and exceptions for applying GAAP to debt, derivatives, and other contracts affected by reference rate reform. The standard is effective for all entities as of March 12, 2020 through December 31, 2022 and may be elected over time as reference rate reform activities occur. The Company does not believe that this ASU will have a material impact upon its consolidated financial statements. Amortized Cost and Fair Value for Certain Non-Recourse Securitization Obligations of Angel Oak Mortgage Trust (“AOMT”) The Company had previously elected the fair value option for many of its assets and liabilities as provided for under Accounting Standards Codification 825, Financial Instruments, with certain exceptions. The Company has recorded the issuances of non-recourse securitization obligations of AOMT 2021-7 and 2021-4 at amortized cost, and subsequent securitization issuances at fair value (See Note 2 - Variable Interest Entities and Note 10 - Fair Value Measurements ). The valuation methodology used to measure the fair value of the Company’s non-recourse securitization obligations, collateralized by residential mortgage loans, uses the prices of the underlying bonds securing the related residential mortgage loans in securitization trusts. The Company utilizes Price Serve , Bank of America’s independent fixed income pricing service, as the primary valuation source for these bonds. Price Serve obtains its price quotes from actual sales or quotes for sale of the same or similar securities and/or provides model‑based valuations that consider inputs derived from recent market activity including default rates, conditional prepayment rates, loss severity, expected yield to maturity, baseline discount margin/yield, recovery assumptions, tranche type, collateral coupon, age and loan size, and other inputs specific to each security. We believe that these quotes are most reflective of the price that would be achieved if the bonds were sold to an independent third party on the date of the condensed consolidated financial statements. This liability is categorized as Level 2 in the fair value hierarchy. Debt issuance costs for non-recourse securitization obligations electing the fair value option are recorded to expense upon issuance of the securitization. Debt issuance costs incurred with the issuances of non-recourse securitization obligations for which the fair value option was not elected are presented at amortized cost.

Variable Interest Entities

Variable Interest Entities	9 Months Ended
	Sep. 30, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities Since its inception, the Company has utilized Variable Interest Entities (“VIEs”) for the purpose of securitizing whole mortgage loans to obtain long-term non-recourse financing. The Company evaluates its interest in each VIE to determine if it is the primary beneficiary. VIEs for Which the Company is the Primary Beneficiary In 2021 and 2022, the Company entered into securitization transactions where it was determined that the Company was the primary beneficiary, as, with respect to each securitization vehicle, it controls the class of securities with call rights, or “controlling class” of securities, the XS tranche. The Company was the sole entity to contribute residential whole mortgage loans to these securitization vehicles. During the three months ended September 30, 2022, in the AOMT 2022-4 transaction, the Company securitized and consolidated approximately $184.7 million unpaid principal balance of seasoned residential non-QM mortgage loans. During the nine months ended September 30, 2022, in the AOMT 2022-4 and the AOMT 2022-1 transactions, the Company securitized and consolidated approximately $722.3 million unpaid principal balance of seasoned residential non-QM mortgage loans. The retained beneficial interest in VIEs for which the Company is the primary beneficiary is the subordinated tranches of the securitization and further interests in additional interest‑only tranches.

VIEs for Which the Company is Not the Primary Beneficiary In 2019 and 2020, the Company co‑sponsored and participated in the formation of various entities that were considered to be VIEs. These VIEs were formed to facilitate securitization issuances that were comprised of secured residential whole loans and/or small balance commercial loans contributed to securitization trusts. These securities were issued as a result of the unconsolidated securitizations where the Company retained bonds from the issuances of AOMT 2019-2, AOMT 2019-4, AOMT 2019-6, AOMT 2020-3, and AOMT 2020-SBC1. The Company determined that it was not then and is not now the primary beneficiary of any of these entities, and thus has not consolidated the operating results or statements of financial position of any of these entities. The Company performs ongoing reassessments of all VIEs in which the Company has participated since its inception as to whether changes in the facts and circumstances regarding the Company’s involvement with a VIE would cause the Company’s consolidation conclusion to change, and the Company’s assessment of the VIEs in which the Company participated during the years 2019 and 2020 remains unchanged. The securities received in the aforementioned 2019 and 2020 securitization transactions are included in “RMBS - at fair value” and “CMBS - at fair value” on the consolidated balance sheets as of September 30, 2022 and December 31, 2021, and details on the accounting treatment and fair value methodology of the securities can be found in Note 10, Fair Value Measurements .

Notes Payable [Abstract]
Notes Payable	Notes Payable The Company has the ability to finance residential and commercial whole loans, utilizing lines of credit (notes payable) from various counterparties, as further described below. Outstanding borrowings bear interest at floating rates depending on the lending counterparty, the collateral pledged, and the rate in effect for each interest period, as the same may change from time to time at the end of each interest period. Some loans include upfront fees, fees on unused balances, covenants and concentration limits on types of collateral pledged; all vary based on the counterparty. Occasionally, a lender may require certain margin collateral to be posted on a warehouse line of credit. Restricted cash as of September 30, 2022 included $7.6 million in margin collateral required by a lender, all of which was released in full subsequent to September 30, 2022. There was no such margin collateral required as of December 31, 2021. The following table sets forth the details of all the lines of credit available to the Company and drawn amounts for whole loan purchases as of September 30, 2022 and December 31, 2021: Drawn Amount Line of Credit Facility Limit Base Interest Rate (A) Interest Rate Spread (A) September 30, December 31, ($ in thousands) Multinational Bank 1 (1) $ 600,000 Average Daily SOFR 1.95% $ 464,695 N/A Multinational Bank 2 (2) $ 400,000 1 month SOFR 1.95% - 2.00% $ 147,261 $ 362,899 Global Investment Bank 1 (3) $ 300,000 1 month or 3 month SOFR 1.70% - 3.50% $ — 103,149 Global Investment Bank 2 (4) $ 250,000 1 month SOFR 2.20% - 3.45% $ 98,335 231,981 Global Investment Bank 3 (5) $ 200,000 Compound SOFR 2.45% $ 117,082 109,283 Regional Bank 1 (6) $ 75,000 1 month SOFR 2.50% - 3.50% $ 50,834 34,838 Regional Bank 2 (7) $ 75,000 1 month SOFR 2.41% $ 28,114 11,258 Total $ 1,900,000 $ 906,321 $ 853,408 (A) See below for timing of applicable transitions from LIBOR to the Secured Overnight Financing Rate (“SOFR”) as base interest rate and corresponding applicable definitions of “Term” and “Average” SOFR, and “SOFR base”.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments In the normal course of business, the Company enters into derivative financial instruments to manage its exposure to market risk, including interest rate risk and prepayment risk on its whole loan investments. The derivatives in which the Company invests, and the market risk that the economic hedge is intended to mitigate are further discussed below. Derivative instruments as of September 30, 2022 and December 31, 2021 included both TBAs and interest rate futures contracts. Restricted cash as of September 30, 2022 included $0.3 million in interest rate futures margin collateral. There was no TBA margin collateral required as of September 30, 2022. Restricted cash as of December 31, 2021 included $2.3 million in TBA margin collateral and $4.2 million in interest rate futures margin collateral. The Company uses interest rate futures as economic hedges to hedge a portion of its interest rate risk exposure. Interest rate risk is sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations, as well as other factors. The Company’s credit risk with respect to economic hedges is the risk of default on its investments that result from a borrower’s or counterparty’s inability or unwillingness to make contractually required payments. The Company may at times hold TBAs in order to mitigate its interest rate risk on certain specified mortgage-backed securities. Amounts or obligations owed by or to the Company are subject to the right of set-off with the TBA counterparty. As part of executing these trades, the Company may enter into agreements with its TBA counterparties that govern the transactions for the TBA purchases or sales made, including margin maintenance, payment and transfer, events of default, settlements, and various other provisions. Changes in the value of derivatives designed to protect against mortgage-backed securities fair value fluctuations, or economic hedging gains and losses, are reflected in the tables below. All realized and unrealized gains and losses on derivative contracts are recognized in earnings, in “net realized gain (loss) on mortgage loans, derivative contracts, RMBS, and CMBS” for realized losses, and “net unrealized (loss) gain on mortgage loans and derivative contracts” for unrealized gains and losses. The Company considers the notional amounts, categorized by primary underlying risk, to be representative of the volume of its derivative activities. The following table sets forth the derivative instruments presented on the condensed consolidated balance sheets and notional amounts as of September 30, 2022 and December 31, 2021: Notional Amounts As of: Derivatives Not Designated as Hedging Instruments Number of Contracts Assets Liabilities Long Exposure Short Exposure ($ in thousands) September 30, 2022 Interest rate futures 10,196 $ 6,612 $ — $ — $ 1,019,600 September 30, 2022 TBAs N/A $ 1,922 $ — $ — $ 1,062,100 December 31, 2021 Interest rate futures 10,438 $ — $ (728) $ — $ 1,043,800 December 31, 2021 TBAs N/A $ 2,428 $ — $ — $ 523,938 The gains and losses arising from these derivative instruments in the condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended September 30, 2022 and September 30, 2021 are set forth as follows: Derivatives Not Designated as Hedging Instruments Net Realized Gains (Losses) on Derivative Instruments Net Change in Unrealized Appreciation (Depreciation) on Derivative Instruments (in thousands) Three Months Ended September 30, 2022 Interest rate futures $ 17,692 $ 6,027 Three Months Ended September 30, 2022 TBAs $ (10,147) $ 10,180 Three Months Ended September 30, 2021 Interest rate futures $ 39 $ 1,666 Three Months Ended September 30, 2021 TBAs $ (5,378) $ 1,305 Derivatives Not Designated as Hedging Instruments Net Realized Gains (Losses) on Derivative Instruments Net Change in Unrealized Appreciation (Depreciation) on Derivative Instruments (in thousands) Nine Months Ended September 30, 2022 Interest rate futures $ 66,805 $ 7,349 Nine Months Ended September 30, 2022 TBAs $ 3,032 $ (506) Nine Months Ended September 30, 2021 Interest rate futures $ (431) $ 2,678 Nine Months Ended September 30, 2021 TBAs $ (7,822) $ 1,120

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements For financial reporting purposes, we follow a fair value hierarchy established under GAAP that is used to determine the fair value of financial instruments. This hierarchy prioritizes relevant market inputs in order to determine an “exit price” at the measurement date, or the price at which an asset could be sold or a liability could be transferred in an orderly process that is not a forced liquidation or distressed sale. Level 1 inputs are observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2 inputs are observable inputs other than quoted prices for an asset or liability that are obtained through corroboration with observable market data. Level 3 inputs are unobservable inputs (e.g., our own data or assumptions) that are used when there is little, if any, relevant market activity for the asset or liability required to be measured at fair value. In certain cases, inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, the level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. Our assessment of the significance of a particular input requires judgment and considers factors specific to the asset or liability being measured. As of September 30, 2022, our valuation policy and processes had not changed from those described in our consolidated financial statements for the year ended December 31, 2021 included in the Annual Report on Form 10-K, with the exception of electing the fair value option for two new non-recourse securitization obligations added in 2022, collateralized by residential mortgage loans, as described in Note 1. Included in Note 10 to the Consolidated Financial Statements for the year ended December 31, 2021 included in the Annual Report on Form 10-K is a detailed description of our other financial instruments measured at fair value and their significant inputs, as well as the general classification of such instruments pursuant to the Level 1, Level 2, and Level 3 valuation hierarchy. The fair value of cash, restricted cash, principal and interest receivable, deferred tax assets and liabilities, other assets (principally consisting of prepaid assets), securities sold under obligation to repurchase, amounts due to broker and accrued expenses (including those payable to an affiliate and management fees payable to an affiliate), and interest payable approximate their carrying values.due to the nature of these assets and liabilities. The following table sets forth information about the Company’s financial assets and liabilities measured at fair value as of September 30, 2022: Level 1 Level 2 Level 3 Total Assets, at fair value (in thousands) Residential mortgage loans $ — $ 1,065,173 $ 4,303 $ 1,069,476 Residential mortgage loans in securitization trust — 1,058,778 3,807 1,062,585 Commercial mortgage loans — 9,554 — 9,554 Investments in securities Non-Agency RMBS (1) — 64,514 — 64,514 Agency whole pool loan securities — 1,004,158 — 1,004,158 AOMT CMBS (2) — 8,857 — 8,857 Unrealized appreciation on futures contracts 6,612 — — 6,612 Unrealized appreciation on TBAs 1,922 — — 1,922 Total assets at fair value $ 8,534 $ 3,211,034 $ 8,110 $ 3,227,678 Liabilities, at fair value Non-recourse securitization obligation, collateralized by residential mortgage loans (3) $ — $ 562,564 $ — $ 562,564 Total liabilities at fair value $ — $ 562,564 $ — $ 562,564 (1) Non‑Agency RMBS held as of September 30, 2022 included both retained tranches of securitizations in which the Company participated and additional AOMT securities purchased in secondary market transactions. (2) All AOMT CMBS held as of September 30, 2022 were comprised of a small-balance commercial loan securitization issuance in which the Company participated. (3) Only the portion subject to fair value measurement, as adjusted for fair value, is presented above. See below for the disclosure of the full debt at fair value. Transfers from Level 2 to Level 3 were comprised of residential loans more than 90 days overdue (including those in foreclosure). Transfers between Levels are deemed to take place on the first day of the reporting period in which the transfer has taken place. These transfers were not material. All unrealized gains and losses arising from valuation changes in residential and commercial mortgage loans, TBAs, and futures contracts are recognized in net income (loss) for the periods presented. We use third‑party valuation firms who utilize proprietary methodologies to value our residential and commercial loans. These firms generally use both market comparable information and discounted cash flow modeling techniques to determine the fair value of our Level 3 assets. Use of these techniques requires determination of relevant input and assumptions, some of which represent significant unobservable inputs such as anticipated credit losses, prepayment rates, default rates, or other valuation assumptions. Accordingly, a significant increase or decrease in any of these inputs in isolation may result in a significantly lower or higher fair value measurement. The following table sets forth information regarding the Company’s significant Level 3 inputs as of September 30, 2022: Input Values Asset Fair Value Unobservable Input Range Average ($ in thousands) Residential mortgage loans, at fair value $ 4,303 Prepayment rate (annual CPR) —% - 13.52% 6.10% Default rate 3.56% - 19.28% 13.69% Loss severity (21.09)% - 14.58% 0.80% Expected remaining life 1.07 - 2.59 years 2.09 years Residential mortgage loans in securitization trust, at fair value $ 3,807 Prepayment rate (annual CPR) —% - 13.52% 6.10% Default rate 3.56% - 19.28% 13.69% Loss severity (21.09)% - 14.58% 0.80% Expected remaining life 1.07 - 2.59 years 2.09 years Fair Value Disclosure - Non-Recourse Securitization Obligations, Collateralized by Residential Mortgage Loans - Fair Value for Disclosure Purposes Only To determine the fair value of the Company’s non-recourse securitization obligations, collateralized by residential mortgage loans, net, in full, the Company used the prices of the underlying bonds securing the related residential mortgage loans in securitization trusts. The Company utilizes Price Serve , Bank of America’s independent fixed income pricing service, as the primary valuation source for these bonds. Price Serve obtains its price quotes from actual sales or quotes for sale of the same or similar securities and/or provides model‑based valuations that consider inputs derived from recent market activity including default rates, conditional prepayment rates, loss severity, expected yield to maturity, baseline discount margin/yield, recovery assumptions, tranche type, collateral coupon, age and loan size and other inputs specific to each security. These quotes are most reflective of the price that would be achieved if the bonds were sold to an independent third party on the date of the condensed consolidated financial statements. This liability is categorized as Level 2 in the fair value hierarchy, as the valuation model has inputs that are observable for substantially the full term of the liability. As of September 30, 2022, the total amortized cost basis and fair value of our non-recourse securitization obligations was $1.1 billion and $992.9 million, respectively, a difference of approximately $116.8 million (which includes AOMT 2022-1 and AOMT 2022-4, which are marked to fair value; and AOMT 2021-7, and AOMT 2021-4, which are carried at amortized cost, as further described). The difference between the amortized cost and fair value solely attributable to AOMT 2021-4 and 2021-7 is approximately $57.6 million. The difference between the amortized cost basis value and the fair value is derived from the difference between the period-end market pricing of the underlying bonds, as referred to above, and the amortized cost of the obligation. The fair value of the non-recourse securitization debt is not indicative of the amounts at which we could settle this debt.

Interim Financial Statements	Interim Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with the instructions to Article 10-01 of Regulation S-X for interim financial statements. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles in the United States of America (“GAAP”) for complete financial statements. These unaudited condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “Annual Report on Form 10-K”). In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. Such operating results may not be indicative of the expected results for any other interim periods or the entire year. The condensed consolidated financial statements include the accounts of the Company and its wholly‑owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements requires the Company to make a number of significant estimates. These include estimates of fair value of certain assets and liabilities, amounts and timing of credit losses, prepayment rates, and other estimates that affect the reported amounts of certain assets and liabilities as of the date of the condensed consolidated financial statements and the reported amounts of certain
Reclassifications	Reclassifications Certain amounts reported in prior periods in the financial statements have been reclassified to conform to the current year’s presentation. For comparative purposes, and to enhance transparency of the Company’s balance sheet, “other assets” on the condensed consolidated balance sheet as of December 31, 2021 in the amount of $2.4 million have been reclassified to unrealized appreciation on “To be Announced” forward-settling of mortgage-backed securities trades (“TBAs”) and interest rate futures contracts - at fair value, leaving a remaining balance of $2.9 million of other assets.
Recent Accounting Standards - Recently Issued	Recent Accounting Standards - Recently Issued In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updated (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The standard was issued to ease the accounting effects of reform to the London Interbank Offered Rate (“LIBOR”) and other reference rates. The standard provides optional expedients and exceptions for applying GAAP to debt, derivatives, and other contracts affected by reference rate reform. The standard is effective for all entities as of March 12, 2020 through December 31, 2022 and may be elected over time as reference rate reform activities occur. The Company does not believe that this ASU will have a material impact upon its consolidated financial statements.
Variable Interest Entities	VIEs for Which the Company is Not the Primary Beneficiary In 2019 and 2020, the Company co‑sponsored and participated in the formation of various entities that were considered to be VIEs. These VIEs were formed to facilitate securitization issuances that were comprised of secured residential whole loans and/or small balance commercial loans contributed to securitization trusts. These securities were issued as a result of the unconsolidated securitizations where the Company retained bonds from the issuances of AOMT 2019-2, AOMT 2019-4, AOMT 2019-6, AOMT 2020-3, and AOMT 2020-SBC1. The Company determined that it was not then and is not now the primary beneficiary of any of these entities, and thus has not consolidated the operating results or statements of financial position of any of these entities. The Company performs ongoing reassessments of all VIEs in which the Company has participated since its inception as to whether changes in the facts and circumstances regarding the Company’s involvement with a VIE would cause the Company’s consolidation conclusion to change, and the Company’s assessment of the VIEs in which the Company participated during the years 2019 and 2020 remains unchanged.
