Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Angel Oak Mortgage REIT, 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 credit-sensitive investments primarily in newly-originated 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 currently operates primarily through a wholesale channel operated by Angel Oak Mortgage Solutions, LLC 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. The Company achieves certain of its investment objectives by investing a portion of its assets in its wholly‑owned taxable REIT 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. The Company is traded on the New York Stock Exchange under the ticker symbol AOMR. 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 Securities and Exchange Commission-registered investment adviser and an affiliate of Angel Oak Capital Advisors, LLC (“Angel Oak Capital”). The Company has elected to be taxed as a real estate investment trust (a “REIT”) under the Internal Revenue Code of 1986, as amended, commencing with its taxable year ended December 31, 2019. 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, 2022, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (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., fair value changes due to inputs and underlying assumptions as described in Note 10 — Fair Value, 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. New Accounting Standards and Interpretations As of March 31, 2023, there were no new accounting standards or interpretations adopted by the Company that had a material effect on its condensed consolidated financial statements. 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 simplify the presentation of the Company’s condensed consolidated balance sheet, the deferred tax asset has been reclassified to “other assets” on the condensed consolidated balance sheet as of December 31, 2022. See Note 14 — Other Assets. Summary of Significant Accounting Policies The Company’s summary of significant accounting policies as set forth in its Annual Report on Form 10-K remain unchanged. During the period ended March 31, 2023, the Company elected a new accounting classification regarding certain of its investments in debt securities, as further described below, as the Company classifies securities on a trade-by-trade basis upon purchase. The Company did not transfer any securities between classifications. The Company classifies its investments in debt securities in accordance with Accounting Standards Codification 320 - Investments - Debt Securities (“ASC 320”) as “trading,” “available for sale,” or “held to maturity”. Historically, the Company had classified all of its investments in debt securities as available for sale (“AFS”). In the first quarter of 2023, the Company designated its new purchases of Freddie Mac and Fannie Mae-issued whole pool agency residential mortgage-backed securities (“Whole Pool Agency RMBS”) and new purchases of U.S. Treasury securities as trading securities.
