Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation and Consolidation The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and include the accounts of the Company and its wholly‑owned subsidiaries. All significant inter‑company 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 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 consolidated financial statements have been reclassified to conform to the current year’s presentation. These reclassifications had no effect on the reported results of operations of prior years. For comparative purposes, and to simplify the presentation of the Company’s consolidated balance sheet, the Commercial mortgage loans - at fair value, CMBS - at fair value, and Deferred tax assets have been reclassified to “Other assets” on the consolidated balance sheet as of December 31, 2022. See Note 15 — Other Assets . Further, an adjustment has been made to the Consolidated Statements of Cash Flows for the year-ended December 31, 2022, to identify amortization of debt issuance costs, net amortization of premiums and discounts of mortgage loans, and principal payments on residential mortgage loans in securitization trusts. Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”). There were no recent ASUs that are expected to have a significant impact on the Company's consolidated financial statements when adopted or had a significant impact on the Company's consolidated financial statements upon adoption. Variable Interest Entities A variable interest entity (“VIE”) is defined as an entity in which equity investors (i) do not have the characteristics of a controlling financial interest, and/or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. A VIE is required to be consolidated by its primary beneficiary, which is defined as the party that has both (i) the power to control the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. For VIEs that do not have substantial on-going activities, the power to direct the activities that most significantly impact the VIE’s economic performance may be determined by an entity’s involvement with the design and structure of the VIE. The Company’s securitization trusts are structured as VIEs that receive principal and interest on the underlying collateral and distribute those payments to the security holders. The assets held by the securitization entities are restricted in that they can only be used to fulfill the obligations of the securitization entity. The Company’s risks associated with its involvement with these VIEs are limited to its risks and rights as a holder of the security it has retained as well as certain associated risks which may occur when the Company acts as either the sponsor and/or depositor of and the seller, directly or indirectly to, the securitization entities. Determining the primary beneficiary of a VIE requires judgment. The Company determined that for the securitizations it consolidates, its ownership provides the Company with the obligation to absorb losses or the right to receive benefits from the VIE that could be significant to the VIE. In addition, the Company has the power to direct the activities that most significantly impact the VIE’s economic performance. As of December 31, 2023 and 2022, the Company was considered to be a primary beneficiary in certain VIEs which held certain interests in the assets held by consolidated securitization vehicles which were created under the purview of its wholly-owned securitization shelf, Angel Oak Mortgage Trust (“AOMT”) II, LLC. These securitization vehicles are consolidated on the Company’s consolidated balance sheet, and are restricted by the structural provisions of the associated securitization trusts. The recovery of the Company’s investment in the securitization vehicles, if any, will be limited by each securitization vehicle’s distribution provisions. The liabilities of the securitization vehicles, which are also consolidated on the Company’s consolidated balance sheets as of December 31, 2023 and 2022, are non-recourse to the Company, and can only be satisfied using proceeds from each securitization vehicle’s respective asset pool. The assets of securitization entities are comprised of RMBS or residential mortgage loans. See Note 3 - Variable Interest Entities for further discussion of the characteristics of the securities and loans in the Company’s portfolio relating to asset pools arising from securitization transactions. The Company performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE would cause the Company’s consolidation conclusion to change. Segment Reporting Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined it currently operates in a single operating segment and has one reportable segment, which is to acquire, invest in, and finance mortgage‑related assets. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. Cash and Cash Equivalents Cash represents cash deposits held at financial institutions. Cash equivalents include short‑term highly liquid investments of sufficient credit quality that are readily convertible to known amounts of cash and have maturities of three months or less at acquisition. The Company maintains its cash and cash equivalents with major financial institutions. Accounts at these institutions are guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 for each bank. The Company is exposed to credit risk for amounts held in excess of the FDIC limit. The Company does not anticipate nonperformance by these financial institutions. Restricted Cash Restricted cash represents cash held at financial institutions for margin on whole loans required by certain counterparties, margin on futures trading activity, and short-term cash collateral for repurchase agreements. A reconciliation of the amounts of cash and cash equivalents and restricted cash in the consolidated balance sheets to the amount in the consolidated statements of cash flows is as follows: December 31, 2023 December 31, 2022 Cash and cash equivalents $ 41,625 $ 29,272 Restricted cash 2,871 10,589 Cash, cash equivalents and restricted cash as show in the statement of cash flows $ 44,496 $ 39,861 Fair Value Measurements The Company reports various investments at fair value in accordance with Accounting Standards Codification (“ASC”) 820, Fair Value Measurement . A fair value measurement represents the price at which an orderly transaction would occur between willing market participants at the measurement date. This definition of fair value focuses on exit price and prioritizes the use of market‑based inputs over entity‑specific inputs when determining fair value. In addition, the framework for measuring fair value establishes a three‑level hierarchy for fair value measurements based upon the observability of inputs to the valuation of an asset or liability as of the measurement date. See Note 10, Fair Value Measurements for further discussion on fair value measurements. The Company accounts for any purchases or sales of Investment Securities on a trade date basis. At the time of disposition, realized gains or losses on sales of Investment Securities are determined based on a specific identification basis and are a component of “net realized gain (loss) on mortgage loans, derivative contracts, RMBS, and CMBS” in the consolidated statements of operations and comprehensive income (loss). RMBS, CMBS, and U.S. Treasury Securities (“Investment Securities”), at Fair Value; and Purchase and Sale of Investment Securities The Company classifies its investments in RMBS, CMBS, and U.S. Treasury Securities as either trading or available-for-sale (“AFS”). Trading Investment Securities are carried at their estimated fair values and coupon interest is recognized as interest income when earned and deemed collectible. Changes in fair value are reported in current earnings in “net unrealized loss on mortgage loans, debt at fair value option, and derivative contracts” in the consolidated statements of operations and comprehensive income (loss) Available-for-sale Investment Securities are carried at their estimated fair value with unrealized gains and losses reported in other comprehensive income (loss) in the consolidated statements of operations and comprehensive income (loss). Residential Mortgage Loans, Residential Mortgage Loans in Securitization Trusts, and Commercial Mortgage Loans, at Fair Value The Company’s investments in residential mortgage loans, including those held in securitization trusts, and commercial loans are recorded using the fair value option in ASC Topic 825 - Financial Instruments , and therefore recorded at fair value in the consolidated balance sheets. Changes in fair value are reported in current earnings in “net unrealized loss on mortgage loans, debt at fair value option, and derivative contracts” in the consolidated statements of operations and comprehensive income (loss). Residential and commercial mortgage loans include loans that the Company may be marketing for sale to third parties, including transfers to securitization entities with either solely contributed loans or with loans contributed to securitization entities along with other Angel Oak entities. When the Company obtains possession of real property in connection with a foreclosure or similar action, the Company de-recognizes the associated mortgage loan according to ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (“ASU 2014-04”). Under the provisions of ASU 2014-04, the Company is deemed to have received physical possession of real estate property collateralizing a mortgage loan when it obtains legal title to the property upon completion of a foreclosure or when the borrower conveys all interest in the property to it through a deed in lieu of foreclosure or similar legal agreement. The Company’s cost basis in REO is equal to the lower of cost or fair value of the real estate associated with the foreclosed mortgage loan, less expected costs to sell. The fair value of such REO is typically based on management’s estimates which generally use information including general economic data, broker opinions of value, recent sales, property appraisals, and bids, and takes into account the expected costs to sell the property. REO recorded at fair value on a non-recurring basis are classified as Level 3. Non-recourse securitization obligations, collateralized by residential mortgage loans (a portion of which is at Fair Value) The portion of this obligation for which we have elected the fair value option uses the prices of the underlying bonds securing the related residential mortgage loans in securitization trusts to determine fair value. Changes in fair value are reported in current earnings in “net unrealized loss on mortgage loans, debt at fair value option, and derivative contracts” in the consolidated statements of operations and comprehensive income (loss). The Company also discloses fair value for the portion of this obligation for which we have elected to hold at amortized cost. See Note 10, Fair Value Measurements. Derivative Financial Instruments, at Fair Value The Company uses a variety of derivative instruments to economically hedge a portion of its exposure to market risks, including interest rate risk and prepayment risk. Derivatives are accounted for in accordance with ASC 815, Derivatives and Hedging , which requires recognition of all derivatives as either assets or liabilities at fair value on the consolidated balance sheets. These derivative financial instrument contracts are not designated as hedges for U.S. GAAP purposes; therefore, all changes in fair value are recognized in earnings. See Note 10, Derivative Financial Instruments for further information. Revenue Recognition Investment Securities Interest income on Investment Securities is recognized based on outstanding principal balances and contractual terms. Premiums and discounts are generally amortized into interest income over the life of such securities using the effective yield method. Adjustments to premium amortization are made for actual prepayments and impact net realized gains (losses). Residential and Commercial Mortgage Loans Interest income on residential mortgage loans and commercial mortgage loans is recognized using the effective interest method over the life of the loans. The amortization of any premiums and discounts is included in interest income. Interest income recognition is suspended when residential mortgage loans or commercial mortgage loans are placed on non-accrual status. Generally, residential mortgage loans and commercial mortgage loans are placed on non-accrual status when delinquent for more than ninety (90) days or when determined not to be probable of full collection. Interest accrued, but not collected, at the date residential mortgage loans or commercial mortgage loans are placed on nonaccrual status is reversed against interest income and subsequently recognized only to the extent it is received in cash or until it qualifies for return to accrual status. Interest received after the loan becomes past due or impaired is used to reduce the outstanding loan principal balance. Repurchase Agreements At times, the Company finances purchases of residential and commercial mortgage loans and Investment Securities through the use of repurchase agreements. The repurchase agreements are treated as collateralized financing transactions, which expire within approximately one year or less and are carried at their contractual amounts, including accrued interest as specified in the respective agreements. Interest paid and accrued in accordance with repurchase agreements is recorded as interest expense. Earnings Per Share The Company computes earnings per share (“EPS”) using the two-class method. The two-class method of computing EPS is an earnings allocation formula that determines EPS for common stock and any participating securities according to dividends declared and participation rights in undistributed earnings. Basic net income (loss) per share is computed by dividing net income (loss) allocable to common stockholders by the weighted‑average number of shares of common stock outstanding during the period. Diluted EPS is calculated by dividing net income (loss) allocable to common stockholders by the weighted average number of shares of common stock outstanding plus the additional dilutive effect of common stock equivalents and dividends related to unvested share-based awards, during each period, unless anti-dilutive. Share-Based Compensation The Company amortizes the fair value of previously granted share-based awards to expense over the vesting period using the straight line method. The initial cost of share-based awards is established at the Company’s closing share price on the grant date of the award. The Company recognizes adjustments for forfeitures as they occur. The Company has made annual grants of performance share units (“PSUs”), which allow for a 50% vest after a three-year period and 50% vest after a four-year period, subject to both continued employment and the achievement of certain performance criteria. Features of the performance criteria constitute a “market condition,” which may impact the amount of compensation expense recognized for these awards. Income Taxes The Company has elected to be taxed as a REIT under the Code starting with its taxable year ended December 31, 2019. Accordingly, the Company will generally not be subject to corporate U.S. federal income tax to the extent that the Company makes qualifying distributions to stockholders, and provided that the Company satisfies, on a continuing basis, through actual investment and operating results, the REIT requirements, including certain asset, income, distribution, and stock ownership tests. If the Company fails to qualify as a REIT, and does not qualify for certain statutory relief provisions, the Company will be subject to U.S. federal, state, and any applicable local income taxes and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year in which the Company lost its REIT qualification. Accordingly, the failure to qualify as a REIT could have a material adverse impact on the Company’s results of operations and amounts available for distribution to stockholders. The dividends paid deduction for qualifying dividends paid to stockholders is computed using the Company’s taxable income as opposed to net income reported in the consolidated statements of operations and comprehensive income (loss). Taxable income will generally differ from net income reported in the consolidated statements of operations and comprehensive income (loss) because the determination of taxable income is based on tax regulations and not U.S. GAAP. The Company has created and elected to treat AOMR TRS as a taxable REIT subsidiary (“TRS”). In general, a TRS may hold assets and engage in activities that the Company cannot hold or engage in directly and generally may engage in any real estate or non‑real estate‑related business. A domestic TRS is subject to U.S. federal, state, and local corporate income taxes, and the value of the securities of the TRS together with the value of the securities of any other TRS owned by the Company may not exceed 20% of the value of the Company’s total assets. If the TRS generates net income, it may declare dividends to the Company, which will be included in the Company’s taxable income and may necessitate a distribution to its stockholders to satisfy distribution requirements and to avoid U.S. federal income and excise tax. Conversely, if the Company retains earnings at the TRS level, no distribution is required. Effective for tax years beginning after December 31, 2022, the Inflation Reduction Act, which was signed into law on August 16, 2022, imposes a 15% alternative minimum tax (“AMT”) on the adjusted financial statement income (“AFSI”) of “Applicable Corporations”. The term “Applicable Corporations” does not include REITs but does include TRSs whose three-year average AFSI exceeds $1 billion. Current and deferred taxes are recorded on earnings (losses) recognized by AOMR TRS. Deferred income tax assets and liabilities are calculated based upon temporary differences between the Company’s U.S. GAAP consolidated financial statements and the U.S. federal and state tax basis of assets and liabilities as of the consolidated balance sheet date. If any deferred tax assets exist, the Company evaluates the realizability of such, and subsequently may recognize a valuation allowance if, based on available evidence, it is more likely than not that some or all of its deferred tax assets will not be realized. In evaluating the realizability of a deferred tax asset, the Company will consider expected future taxable income, existing and projected book to tax differences, and any tax planning strategies. Such an analysis is inherently subjective, as it is based on forecast earnings and business and economic activity. See Note 12 — Income Taxes , for further details regarding the Company’s deferred tax assets. As a REIT, if the Company fails to distribute in any calendar year (subject to specific timing rules for certain dividends paid in January) at least the sum of (i) 85% of its ordinary income for such year, (ii) 95% of its capital gain net income for such year, and (iii) any undistributed taxable income from the prior year, the Company would be subject to a nondeductible 4% excise tax on the excess of such required distribution over the sum of (i) the amounts actually distributed and (ii) the amounts of income retained and on which the Company has paid U.S. federal corporate income tax. Risks and Uncertainties Credit Risk The Company assumes credit risk through its investments in mortgage loans and other mortgage‑related assets. Credit losses on mortgage loans can occur for many reasons, including: fraud; poor underwriting; poor servicing practices; weak economic conditions; increases in payments required to be made by borrowers; declines in the value of real estate; declining rents on single‑ and multi‑family residential rental properties; natural disasters, including the effects of climate change (including flooding, drought, wildfires, and severe weather), and other natural events; uninsured property loss; over‑leveraging of the borrower; costs of remediation of environmental conditions, such as indoor mold; changes in zoning or building codes and the related costs of compliance; acts of war or terrorism; changes in legal protections for lenders and other changes in law or regulation; and personal events affecting borrowers, such as reduction in income, job loss, divorce, or health problems. In addition, the amount and timing of credit losses could be affected by loan modifications, delays in the liquidation process, documentation errors, and other action by servicers. Weakness in the U.S. economy or the housing market could cause the Company’s credit losses to increase. In addition, rising interest rates may increase the credit risk associated with certain residential mortgage loans. For example, the interest rate is adjustable for many of the loans held by the Company or within the securitization entities in which the Company participates. In addition, a portion of the loans the Company has pledged to secure loan financing lines have adjustable interest rates. Accordingly, when short‑term interest rates rise, required monthly payments from homeowners will rise under the terms of these adjustable‑rate mortgages, and this may increase borrowers’ delinquencies and defaults. Credit losses on commercial mortgage loans can occur for many of the reasons noted above for residential mortgage loans. Moreover, these types of real estate loans may not be fully amortizing and, therefore, the borrower’s ability to repay the principal when due may depend upon the ability of the borrower to refinance or sell the property at maturity. Business purpose real estate loans are particularly sensitive to conditions in the rental housing market and to demand for rental residential properties. Within a securitization of residential, multi‑family, or business purpose real estate loans, various securities are created, each of which has varying degrees of credit risk. The Company may own the securities in which there is more (or the most) concentrated credit risk associated with the underlying real estate loans. In general, losses on an asset securing a loan or loan included as collateral to a securitization will be borne first by the owner of the property (i.e., the owner will first lose any equity invested in the property) and, thereafter, by the first loss security holder, and then by holders of more senior securities. In the event the losses incurred upon default on the loan exceed any classes in which the Company invests, the Company may not be able to recover all of its investment in the securities it holds. In addition, if the underlying properties have been overvalued by the originating appraiser or if the values subsequently decline and, as a result, less collateral is available to satisfy interest and principal payments due on the related security, then the first‑loss securities may suffer a total loss of principal, followed by losses on the second‑loss and then third‑loss securities (or other residential and commercial securities that the Company owns). In addition, with respect to residential securities the Company owns, the Company may be subject to risks associated with the determination by a loan servicer to discontinue servicing advances (advances of mortgage interest payments not made by a delinquent borrower) if they deem continued advances to be unrecoverable, which could reduce the value of these securities or impair the Company’s ability to project and realize future cash flows from these securities. Investments in subordinated RMBS and CMBS involve greater credit risk than the senior classes of the issue or series. Many of the default‑related risks of whole loan mortgages will be magnified in subordinated securities. Default risks may be further pronounced in the case of RMBS and CMBS by, or evidencing an interest in, a relatively small or less diverse pool of underlying mortgage loans. Certain subordinated securities absorb all losses from default before any other class of securities is at risk, particularly if such securities have been issued with little or no credit enhancement or equity. In addition, principal payments on subordinated securities may be subject to a “lockout” period in which some or all of the principal payments are directed to the related senior securities. This lock‑out period may be for a set period of time and/or may be determined based on pool performance criteria such as losses and delinquencies. Such securities therefore possess some of the attributes typically associated with equity investments. Interest Rate Risk Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond the Company’s control. A significant portion of the Company’s financial assets and liabilities, including the Company’s whole loan investments (which include residential mortgage loans, residential mortgage loans held in securitization trusts, and commercial loans), investment securities, loan financing facilities, and security repurchase facilities, are interest earning or interest bearing and, as a result, the Company is subject to risks arising from fluctuations in the prevailing levels of market interest rates. In addition, all of the Company’s warehouse loan financing arrangements (notes payable) have a variable rate component or include rates which reset monthly and add additional risk due to fluctuations in market interest rates. Any excess cash and cash equivalents of the Company are invested in instruments earning short‑term market interest rates. Subject to maintaining its qualification as a REIT and maintaining its exclusion from regulation as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”), the Company may utilize various derivative instruments and other hedging instruments to mitigate interest rate risk. Liquidity Risk An insufficient secondary market may prevent the liquidation of an asset or limit the funds that can be generated from selling an asset. A portion of the Company’s financial assets are considered to be illiquid and may be subject to high liquidity risk. Furthermore, the Company’s use of financial leverage exposes the Company to increased liquidity risks from margin calls and potential breaches of the financial covenants under its borrowing facilities, which could result in the Company being required to immediately repay all outstanding amounts borrowed under these facilities and these facilities being unavailable to use for future financing needs, as well as triggering cross-defaults under other debt agreements. Prepayment Risk The frequency at which prepayments occur on loans held and loans underlying RMBS and CMBS will be affected by a variety of factors including the prevailing level of interest rates as well as economic, demographic, tax, social, legal, and other factors. Generally, mortgage obligors tend to prepay their mortgages when prevailing mortgage rates fall below the interest rates on their mortgage loans. Generally, whole loans, RMBS, and CMBS purchased at a premium are adversely affected by faster than anticipated prepayments; and whole loans, RMBS, and CMBS purchased at a discount are adversely affected by slower than anticipated prepayments. The adverse effects of prepayments may impact the Company in two ways. First, particular investments may experience outright losses, as in the case of an interest‑only security in an environment of faster actual or anticipated prepayments. Second, particular investments may underperform relative to the financial instruments that the Company’s Manager may have constructed to reduce specific financial risks for these investments, resulting in a loss to the Company. In particular, prepayments (at par) may limit the potential upside of many whole loans, RMBS, and CMBS to their principal or par amounts, whereas their corresponding hedges, if any, often have the potential for unlimited loss. Extension Risk The Company’s Manager computes the projected weighted average life of the Company’s investments based on assumptions regarding the rate at which the borrowers will prepay the underlying mortgage loans. In general, when fixed rate, adjustable rate, or hybrid mortgage loans or other mortgage‑related assets are acquired via borrowings, the Company may, but is not required to, enter into an interest rate swap agreement or other economic hedging instrument that attempts to fix the Company’s borrowing costs for a period close to the anticipated average life of the fixed rate portion of the related assets, in each case subject to maintaining the Company’s qualification as a REIT and maintaining the Company’s exclusion from regulation as an investment company under the Investment Company Act. This strategy is designed to protect the Company from rising interest rates, as the borrowing costs are managed to maintain a net interest spread for the duration of the fixed rate portion of the related assets. However, if prepayment rates decrease in a rising interest rate environment, the life of the fixed rate portion of the related assets could extend beyond the term of the swap agreement or other hedging instrument. This could have an adverse impact on the Company’s earnings, as borrowing costs would no longer be fixed after the end of the hedging instrument, while the income earned on the fixed rate, adjustable rate, or hybrid assets would remain fixed. In extreme situations, the Company may be forced to sell assets to maintain adequate liquidity, which could cause the Company to incur losses. |
