1. Organization

AG Mortgage Investment Trust, Inc. (the "Company") is a residential mortgage REIT with a focus on investing in a diversified risk-adjusted portfolio of residential mortgage-related assets in the U.S. mortgage market. The Company’s investment activities primarily include acquiring and securitizing newly-originated residential mortgage loans within the non-agency segment of the housing market. The Company obtains its assets through Arc Home, LLC ("Arc Home"), a residential mortgage loan originator in which the Company owns an approximate 44.6% interest, and through other third-party origination partners.

The Company’s assets, excluding its ownership in Arc Home, include Residential Investments and Agency RMBS. Currently, its Residential Investments primarily consist of newly originated Non-Agency Loans and Agency-Eligible Loans. The Company may invest in other types of residential mortgage loans and other mortgage related assets. The Company also invests in Residential Investments through its unconsolidated ownership interests in affiliates which are included in the "Investments in debt and equity of affiliates" line item on its consolidated balance sheets.

The Company's asset classes are primarily comprised of the following:

Asset Class Description

Residential Investments

Non-Agency Loans(1)

• Non-Agency Loans are loans that do not conform to the underwriting guidelines of a government-sponsored enterprise ("GSE"). Non-Agency Loans consist of Qualified mortgage loans ("QM Loans") and Non-Qualified mortgage loans ("Non-QM Loans"). QM Loans are residential mortgage loans that comply with the Ability-To-Repay rules and related guidelines of the Consumer Finance Protection Bureau.

Agency-Eligible Loans(1)

• Agency-Eligible Loans are loans that are underwritten in accordance with GSE guidelines and are primarily secured by investment properties, but are not guaranteed by a GSE. Although these loans are underwritten in accordance with GSE guidelines and can be delivered to Fannie Mae and Freddie Mac, the Company includes these loans within its Non-Agency securitizations.

Re- and Non-Performing Loans(1)

• Performing, re-performing, and non-performing loans are residential mortgage loans collateralized by a first lien mortgaged property.

Non-Agency Residential Mortgage-Backed Securities ("RMBS")(2)

• Non-Agency RMBS represent fixed- and floating-rate RMBS issued by entities other than U.S. GSEs or agencies of the U.S. government. The mortgage loan collateral consists of either Non-Agency Loans or Agency-Eligible Loans.

Agency RMBS(2)

• Agency RMBS represent interests in pools of residential mortgage loans guaranteed by a GSE such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government such as Ginnie Mae.

(1) These investments are included in the "Securitized residential mortgage loans, at fair value," "Residential mortgage loans, at fair value," and "Residential mortgage loans held for sale, at fair value" line items on the consolidated balance sheets.

(2) These investments are included in the "Real estate securities, at fair value" line item on the consolidated balance sheets.

The Company conducts its business through one reportable segment, Loans and Securities, which reflects how the Company manages its business and analyzes and reports its results of operations.

The Company was incorporated in the state of Maryland on March 1, 2011 and commenced operations in July 2011. The Company conducts its operations to qualify and be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). The Company is externally managed by AG REIT Management, LLC, a Delaware limited liability company (the "Manager"), a wholly-owned subsidiary of Angelo, Gordon & Co., L.P. ("Angelo Gordon"), a diversified credit and real estate investing platform within TPG Inc. ("TPG"). TPG (Nasdaq: TPG) is a leading global alternative asset management firm. The Manager has delegated to Angelo Gordon the overall responsibility of its day-to-day duties and obligations arising under the management agreement.

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Proposed Acquisition of Western Asset Mortgage Capital Corporation

On August 8, 2023, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Western Asset Mortgage Capital Corporation, a Delaware corporation ("WMC"), AGMIT Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company ("Merger Sub"), and, solely for the purposes set forth in the Merger Agreement, the Manager. Pursuant to, and subject to the terms and conditions set forth in the Merger Agreement, WMC will merge with and into Merger Sub, with Merger Sub surviving (the "Merger").

On November 7, 2023, the Company's stockholders approved the issuance of the Company's common stock in connection with the Merger with WMC at a special stockholders meeting. No further Company stockholder approval is required for the Merger. On November 7, 2023, WMC announced it adjourned its special stockholders meeting relating to the Merger until December 5, 2023, at 9:00 a.m., Pacific Time, online in a virtual-only meeting format, due to a lack of quorum and to allow further solicitation of proxies from WMC common stockholders for the approval of the Merger at such special stockholders meeting. The Merger is expected to close in the fourth quarter of 2023, subject to the satisfaction of certain customary conditions, including approval of WMC's common stockholders.

Under the terms of the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each outstanding share of WMC common stock will be converted into the right to receive the following (the "Per Share Merger Consideration"): (i) 1.498 shares, or approximately 9.2 million shares in aggregate, of the Company's common stock; and (ii) the per share portion of a cash payment from the Manager equal to the lesser of $7.0 million or approximately 9.9% of the aggregate Per Share Merger Consideration. Cash will be paid in lieu of any fractional shares of the Company's common stock that would otherwise have been received as a result of the Merger.

In addition, on August 8, 2023, the Company and the Manager entered into an amendment (the “MITT Management Agreement Amendment”) to the existing management agreement, pursuant to which (i) the base management fee will be reduced by $0.6 million for the first four quarters (i.e., resulting in an aggregate $2.4 million waiver of base management fees) following the Effective Time, beginning with the fiscal quarter in which the Effective Time occurs, and (ii) the Manager will waive its right to seek reimbursement from the Company for any expenses otherwise reimbursable by the Company under the management agreement in an amount equal to the excess, if any, of $7.0 million over the aggregate cash portion of the Per Share Merger Consideration paid by the Manager to the holders of WMC common stock in the Merger. The MITT Management Agreement Amendment will become effective automatically upon the closing of the Merger, and will have no force and effect if the Merger does not close.

Further, in the Merger Agreement, the Company has agreed to take all necessary corporate action so that upon and after the Effective Time, the size of the Company's Board of Directors will be increased by two members, and M. Christian Mitchell and Lisa G. Quateman (the "WMC Director Designees") will be appointed to the Company's Board of Directors. The Company has further agreed to nominate the WMC Director Designees to the Company's Board of Directors at the next annual meeting following the Effective Time.

Concurrently with the execution of the Merger Agreement, WMC terminated its merger agreement (the "TPT Merger Agreement") with Terra Property Trust, Inc. ("TPT"). In connection with such termination, the Company, on behalf of WMC, paid to TPT a termination fee of $3.0 million as required by the TPT Merger Agreement (the "TPT Termination Fee").

2. Summary of significant accounting policies

Consolidation and basis of presentation

The accompanying unaudited consolidated financial statements and related notes have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. For the three months ended September 30, 2022, the Company reclassified $2.5 million and $1.6 million of other operating expenses into the "Non-investment related expenses" and "Investment related expenses" line items on the consolidated statement of operations, respectively. For the nine months ended September 30, 2022, the Company reclassified $7.7 million and $3.9 million of other operating expenses into the "Non-investment related expenses" and "Investment related expenses" line items on the consolidated statement of operations, respectively. Furthermore, for the three and nine months ended September 30, 2022, the Company reclassified $1.0 million and $3.0 million of servicing fees into the "Investment related expenses" line item on the consolidated statement of operations, respectively. These expenses were reclassified to conform to the current year presentation of expenses. In the opinion of management, all adjustments considered necessary for a fair statement of the Company’s financial position, results of operations, and cash flows have been included for the interim period and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year.

Significant accounting policies

There have been no significant changes to the Company's accounting policies included in Note 2 to the consolidated financial statements of the Company’s Form 10-K for the year ended December 31, 2022. These unaudited 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 Form 10-K.

Use of estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from those estimates.

Investment consolidation

An entity is a variable interest entity ("VIE") if the equity investors (i) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, (ii) are unable to direct the entity’s activities or (iii) are not exposed to the entity’s losses or entitled to its residual returns. VIEs within the scope of Accounting Standards Codification ("ASC") 810-10, "Consolidation" are required to be consolidated by their primary beneficiary. The primary beneficiary of a VIE is determined to be the party that has both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. This determination can sometimes involve complex and subjective analyses. Further, ASC 810-10 also requires ongoing assessments of whether an enterprise is the primary beneficiary of a VIE. In accordance with ASC 810-10, all transferees, including variable interest entities, must be evaluated for consolidation. If the Company determines that consolidation is not required, it will then assess whether the transfer of the underlying assets would qualify as a sale, should be accounted for as secured financings under GAAP, or should be accounted for as an equity method investment, depending on the circumstances.

A Special Purpose Entity ("SPE") is an entity designed to fulfill a specific limited need of the company that organized it. SPEs are often used to facilitate transactions that involve securitizing financial assets or resecuritizing previously securitized financial assets. The objective of such transactions may include obtaining non-recourse financing, obtaining liquidity or refinancing the underlying securitized financial assets on improved terms. Securitization involves transferring assets to an SPE to convert all or a portion of those assets into cash before they would have been realized in the normal course of business through the SPE’s issuance of debt or equity instruments. Investors in an SPE usually have recourse only to the assets in the SPE and depending on the overall structure of the transaction, may benefit from various forms of credit enhancement, such as over-collateralization in the form of excess assets in the SPE, priority with respect to receipt of cash flows relative to holders of other debt or equity instruments issued by the SPE, or a line of credit or other form of liquidity agreement that is designed with the objective of

ensuring that investors receive principal and/or interest cash flow on the investment in accordance with the terms of their investment agreement.

The Company enters into securitization transactions collateralized by its Non-Agency Loans/Agency-Eligible Loans and re- and non-performing loans (the trusts in which these loans are deposited are referred to as "Non-Agency VIEs" and "RPL/NPL VIEs", respectively), which may result in the Company consolidating the respective VIEs that are created to facilitate these securitizations. Based on the evaluations of each VIE, the Company may conclude that the VIEs should be consolidated and, as a result, transferred assets of these VIEs would be determined to be secured borrowings. Upon consolidation, the Company elected the fair value option pursuant to ASC 825 for the assets and liabilities of the Non-Agency VIEs and RPL/NPL VIEs. Electing the fair value option allows the Company to record changes in fair value in the consolidated statement of operations, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all activities will be recorded in a similar manner. The Company applied the guidance under ASC 810-10 (Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity) whereby the Company determines whether the fair value of the assets or liabilities of the Non-Agency VIEs and RPL/NPL VIEs are more observable as a basis for measuring the less observable financial instruments. The Company has determined that the fair value of the liabilities of the Non-Agency VIEs and RPL/NPL VIEs are more observable since the prices for these liabilities are more easily determined as similar instruments trade more frequently on a relative basis than the individual assets of the VIEs. See Note 3 for more detail regarding the Non-Agency VIEs and RPL/NPL VIEs and Note 5 for more detail related to the Company's determination of fair value for the assets and liabilities included within these VIEs.

Recent accounting pronouncements

In March 2020, FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU provides temporary optional guidance intended to ease the burden of reference rate reform on financial reporting and may be elected over time as reference rate reform activities occur. This ASU is effective as of March 12, 2020 and was amended by ASU 2022-06 to sunset on December 31, 2024. The ASU applies to all entities that have contracts, hedging relationships and other transactions that reference LIBOR and certain other reference rates that are expected to be discontinued. However, it cannot be applied to contract modifications that occur after December 31, 2024. With certain exceptions, this ASU also cannot be applied to hedging relationships entered into or evaluated after that date. The guidance provides optional expedients and exceptions for applying existing guidance to contract modifications, hedging relationships and other transactions that are expected to be affected by reference rate reform and meet certain scope guidance.

The Company has transitioned from LIBOR to an alternative benchmark. The adoption of ASU 2020-04 and the LIBOR transition did not have a material impact on the consolidated financial statements. The Company's primary exposure to LIBOR has historically included its financing arrangements and derivative contracts. In addition, the Company's Series C Preferred Stock is set to transition to a floating rate in September of 2024. At the time of transition, the Company no longer had derivative contracts indexed to LIBOR and all LIBOR-based financing arrangements transitioned to alternative benchmark rates. The Company does not currently intend to amend the Series C Preferred Stock to change the existing LIBOR cessation fallback language.

5. Fair value measurements

The fair value of the Company's financial instruments is determined in accordance with the provisions of ASC 820, "Fair Value Measurements and Disclosures." When possible, the Company determines fair value using third-party data sources. ASC 820 establishes a hierarchy that prioritizes the inputs to valuation techniques. 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 and may include quoted prices for similar assets and liabilities in active markets. Level 3 inputs are significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used and reflect the Company’s assumptions about the factors that market participants would use in pricing an asset or liability, and would be based on the best information available. 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.

The valuation of the Company’s residential mortgage loans, securitized debt relating to the Non-Agency VIEs and RPL/NPL VIEs, certain securities, and forward purchase commitments is determined by the Manager using third-party pricing services where available, valuation analyses from third-party pricing service providers, or model-based pricing. Third-party pricing service providers conduct independent valuation analyses based on a review of source documents, available market data, and comparable investments. The analyses provided by valuation service providers are reviewed and considered by the Manager. The evaluation considers the underlying characteristics of each loan, which are observable inputs, including: coupon, maturity date, loan age, reset date, collateral type, periodic and life cap, geography, and prepayment speeds. The Company also considers loan servicing data, as available, forward interest rates, general economic conditions, home price index forecasts, and valuations of the underlying properties. The variables considered most significant to the determination of the fair value of the Company's residential mortgage loans, securitized debt, and forward purchase commitments include market-implied discount rates, projections of default rates, delinquency rates, prepayment rates, loss severity, recovery rates, reperformance rates, timeline to liquidation, and, for forward purchase commitments, pull-through rates. The Company and third-party pricing service providers use loan level data and macro-economic inputs to generate loss adjusted cash flows and other information in determining the fair value. Because of the inherent uncertainty of such valuation, the fair value established for mortgage loans, securitized debt, and forward purchase commitments held by the Company may differ from the fair value that would have been established if a ready market existed for these mortgage loans.

Fair values for the Company’s securities and derivatives may be based upon prices obtained from third-party pricing services or broker quotations. The valuation methodology of the Company’s third-party pricing services incorporates commonly used market pricing methods, including a spread measurement to various indices, which are observable inputs. The evaluation also considers the underlying characteristics of each investment, which are also observable inputs, including: coupon, maturity date, loan age, reset date, collateral type, periodic and life cap, geography, and prepayment speeds. The Company collects and considers current market intelligence on all major markets, including benchmark security evaluations and bid-lists from various sources, when available. As part of the Company’s risk management process, the Company reviews and analyzes all prices obtained by comparing prices to recently completed transactions involving the same or similar investments on or near the reporting date. If, in the opinion of the Manager, one or more prices reported to the Company are not reliable or unavailable, the Manager reviews the fair value based on characteristics of the investment it receives from the issuer and available market information.

The Company's investment in Arc Home is evaluated on a periodic basis using a market approach. In applying the market approach, fair value is determined by multiplying Arc Home's book value by a relevant valuation multiple observed based on a range of comparable public entities or transactions, adjusted by management as appropriate for differences between the investment and the referenced comparables. The evaluation also considers the underlying financial performance of Arc Home, general economic conditions, and relevant trends within the mortgage banking industry.

Changes in the market environment and other events that may occur over the life of these investments may cause the gains or losses ultimately realized to be different than the valuations currently estimated. The significant unobservable inputs used in the fair value measurement of the Company’s loans and securities are yields, prepayment rates, probability of default, and loss severity in the event of default. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for prepayment rates. The significant unobservable input used in the fair value measurement of the Company’s investment in Arc Home is the book value multiple. Significant increases (decreases) in the multiple applied would result in a significantly higher (lower) fair value measurement.

The Company did not have any transfers of assets or liabilities between Levels 1 and 2 of the fair value hierarchy during the three and nine months ended September 30, 2023 and 2022.

The Company did not have any transfers between the Levels 2 and 3 of the fair value hierarchy during the three and nine months ended September 30, 2023 and 2022. Transfers into the Level 3 category of the fair value hierarchy occur due to instruments exhibiting indications of reduced levels of market transparency. Transfers out of the Level 3 category of the fair value hierarchy occur due to instruments exhibiting indications of increased levels of market transparency. Indications of increases or decreases in levels of market transparency include a change in observable transactions or executable quotes involving these instruments or similar instruments. Changes in these indications could impact price transparency, and thereby cause a change in level designations in future periods.

Derivative and other instruments eligible for offset are presented gross on the consolidated balance sheets as of September 30, 2023 and December 31, 2022, if applicable. The Company has not offset or netted any derivatives or other instruments with any financial instruments or cash collateral posted or received.

The Company must post cash or securities as collateral on its derivative instruments when their fair value declines. This typically occurs when prevailing market rates change adversely, with the severity of the change also dependent on the term of the derivatives involved. The posting of collateral is generally bilateral, meaning that if the fair value of the Company’s derivatives increases, its counterparty must post collateral. As of September 30, 2023, the Company's restricted cash balance included $11.1 million of collateral related to certain derivatives, of which $0.4 million represents cash collateral posted by the Company and $10.7 million represents amounts related to variation margin.

9. Income taxes

The Company conducts its operations to qualify and be taxed as a REIT. As a REIT, the Company is not subject to federal income tax to the extent that it makes qualifying distributions to its stockholders, and provided it satisfies on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution, and stock ownership tests. The state and local tax jurisdictions for which the Company is subject to tax-filing obligations recognize the Company’s status as a REIT, and therefore, the Company generally does not pay income tax in such jurisdictions. The Company may, however, be subject to certain minimum state and local tax filing fees as well as certain excise, franchise, or business taxes.

September 30, 2023

Excise tax represents a non-deductible 4% tax on the required amount of the Company’s ordinary income and net capital gains not distributed during the year. The expense is calculated in accordance with applicable tax regulations. For the three and nine months ended September 30, 2023 and 2022, the Company did not record any excise tax.

Taxable REIT Subsidiaries

The Company elected to treat certain domestic subsidiaries as taxable REIT subsidiaries ("TRSs"). The Company’s financial results are generally not expected to reflect provisions for current or deferred income taxes, except for any activities conducted through one or more TRSs that are subject to corporate income taxation. Currently, the Company has wholly owned domestic TRSs that are taxable as corporations and subject to U.S. federal, state, and local income tax on net income at the applicable corporate rates. The federal statutory rate for the three and nine months ended September 30, 2023 and 2022 was 21%. The Company’s effective tax rate differs from its combined U.S. federal, state, and local corporate statutory tax rate primarily due to income earned at the REIT, which is not subject to tax, due to the deduction for qualifying distributions made by the Company, and any change in the valuation allowance as disclosed in further detail below. The tax expense attributable to its TRS is recorded in the "Non-investment related expenses" line item on the consolidated statement of operations. The below table details the tax expense attributable to the TRS for the three and nine months ended September 30, 2023 and 2022 (in thousands).

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax reporting purposes at the TRS level. As of September 30, 2023 and December 31, 2022, the Company recorded a deferred tax asset of approximately $30.4 million and $30.2 million, respectively, relating to net operating loss carryforwards, capital loss carryforwards, and basis differences of certain investments held within TRSs. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which temporary differences become deductible. The Company concluded it is more likely than not the deferred tax asset will not be realized and established a full valuation allowance as of September 30, 2023 and December 31, 2022.

Uncertain Income Tax Positions

Based on its analysis of any potential uncertain income tax positions, the Company concluded it did not have any uncertain tax positions that meet the recognition or measurement criteria of ASC 740 as of September 30, 2023 and December 31, 2022. The Company’s federal income tax returns for the last three tax years are open to examination by the Internal Revenue Service. There are no ongoing U.S. federal, state or local tax examinations related to the Company. In the event that the Company incurs income tax related interest and penalties, its policy is to classify them as a component of provision for income taxes.

agreement with the Manager, the closing of the TPG Transaction resulted in an assignment of the management agreement. The independent directors of the Company's board of directors unanimously consented to such assignment on July 31, 2023 in advance of the TPG Transaction closing. There were no changes to the management agreement in connection with the TPG Transaction and the assignment of the management agreement became effective upon the closing of the TPG Transaction.

In connection with the proposed Merger with WMC and contemporaneously with the execution of the Merger Agreement, on August 8, 2023, the Company and the Manager entered into the MITT Management Agreement Amendment, pursuant to which (i) the Manager’s base management fee will be reduced by $0.6 million for the first four quarters (i.e., resulting in an aggregate $2.4 million waiver of base management fees) following the Effective Time, beginning with the fiscal quarter in which the Effective Time occurs, and (ii) the Manager will waive its right to seek reimbursement from the Company for any expenses otherwise reimbursable by the Company under the management agreement in an amount equal to the excess, if any, of $7.0 million over the aggregate cash portion of the Per Share Merger Consideration paid by the Manager to the holders of WMC common stock in the Merger. The MITT Management Agreement Amendment will become effective automatically upon the closing of the Merger, and will have no force and effect if the Merger does not close.

Management fee

The Manager is entitled to a management fee equal to 1.50% per annum, calculated and paid quarterly, of the Company’s Stockholders’ Equity. For purposes of calculating the management fee, "Stockholders’ Equity" means the sum of the net proceeds from any issuances of equity securities (including preferred securities) since inception (allocated on a pro rata daily basis for such issuances during the fiscal quarter of any such issuance, and excluding any future equity issuance to the Manager), plus the Company’s retained earnings at the end of such quarter (without taking into account any non-cash equity compensation expense or other non-cash items described below incurred in current or prior periods), less any amount that the Company pays for repurchases of its common stock, excluding any unrealized gains, losses or other non-cash items that have impacted stockholders’ equity as reported in the Company’s financial statements prepared in accordance with GAAP, regardless of whether such items are included in other comprehensive income or loss, or in net income, and excluding one-time events pursuant to changes in GAAP, and certain other non-cash charges after discussions between the Manager and the Company’s independent directors and after approval by a majority of the Company’s independent directors. Stockholders’ Equity, for purposes of calculating the management fee, could be greater or less than the amount of stockholders’ equity shown on the Company’s financial statements.

The below table details the management fees incurred during the three and nine months ended September 30, 2023 and 2022 (in thousands).

As of September 30, 2023 and December 31, 2022, the Company recorded management fees payable of $2.1 million and $2.1 million, respectively. The management fee payable is included within the "Due to affiliates" item within the "Other liabilities" line item on the consolidated balance sheets.

Incentive fee

The Manager is entitled to an annual incentive fee with respect to each applicable fiscal year, which will be equal to 15% of the amount by which the Company's cumulative adjusted net income from November 22, 2021 exceeds the cumulative hurdle amount, which represents an 8% return (cumulative, but not compounding) on an equity hurdle base consisting of the sum of (i) $341.5 million and (ii) the gross proceeds of any subsequent public or private common stock offerings by the Company. The annual incentive fee will be payable in cash, or, at the option of the Company's Board of Directors, shares of common stock or a combination of cash and shares.

The Manager waived the annual incentive fee with respect to the fiscal years ending December 31, 2021 and December 31, 2022, and the annual incentive fee will first be payable with respect to the fiscal year ending December 31, 2023. During the three and nine months ended September 30, 2023, the Company did not incur any incentive fee expense.

Termination fee

Upon the occurrence of (i) the Company’s termination of the management agreement without cause or (ii) the Manager’s termination of the management agreement upon a breach by the Company of any material term of the management agreement, the Manager will be entitled to a termination fee equal to three times the average annual management fee during the 24-month period prior to such termination, calculated as of the end of the most recently completed fiscal quarter. As of September 30, 2023 and December 31, 2022, no event of termination of the management agreement had occurred.

Expense reimbursement

The Company is required to reimburse the Manager or its affiliates for operating expenses which are incurred by the Manager or its affiliates on behalf of the Company, including expenses relating to legal, accounting, due diligence, and other services. The Company’s reimbursement obligation is not subject to any dollar limitation; however, the reimbursement is subject to an annual budget process which combines guidelines from the management agreement with oversight by the Company’s Board of Directors.

The Company reimburses the Manager or its affiliates for the Company’s allocable share of the compensation, including, without limitation, annual base salary, bonus, any related withholding taxes, and employee benefits paid to (i) the Company’s chief financial officer based on the percentage of time spent on Company affairs, (ii) the Company’s general counsel based on the percentage of time spent on the Company’s affairs, and (iii) other corporate finance, tax, accounting, internal audit, legal, risk management, operations, compliance, and other non-investment personnel of the Manager and its affiliates who spend all or a portion of their time managing the Company’s affairs based upon the percentage of time devoted by such personnel to the Company’s affairs.

The number of shares of restricted common stock to be issued each quarter to each independent director is determined based on the average of the high and low prices of the Company’s common stock on the New York Stock Exchange on the last trading day of each fiscal quarter. To the extent that any fractional shares would otherwise be issuable and payable to each independent director, a cash payment is made to each independent director in lieu of any fractional shares.

These shares may not be sold or transferred by such director during the time of their service as an independent member of the Company’s Board of Directors.

The below table details the unpaid principal balance of Non-Agency Loans and Agency-Eligible Loans sold to the Company and private funds under the management of Angelo Gordon during the three and nine months ended September 30, 2023 and 2022 (in thousands).

In connection with the sale of loans from Arc Home to the Company, the Company eliminates any intra-entity profits or losses typically recognized through the "Equity in earnings/(loss) from affiliates" line item on the Company's consolidated statement of operations and adjusts the cost basis of the underlying loans resulting in unrealized gains or losses on the underlying loans. The table below summarizes intra-entity profits eliminated during the three and nine months ended September 30, 2023 and 2022 (in thousands).

As of December 31, 2022, the Company recorded a $0.5 million receivable from Arc Home related to certain loans purchased from Arc Home which was recorded within the "Other assets" line item on the consolidated balance sheets. The Company received payment for the full amount from Arc Home during the current year.

The Company enters into forward purchase commitments with Arc Home whereby the Company commits to purchase residential mortgage loans from Arc Home at a particular price on a best-efforts basis. Actual loan purchases are contingent upon successful loan closings. These commitments to purchase mortgage loans are classified as derivatives. From time to time, the Company may determine that certain loans it has previously committed to purchase will be sold to third parties and, as a result, the derivative will be settled on a net basis with Arc Home. See Note 7 and Note 12 for more detail.

During the year ended December 31, 2022, the Company determined that certain loans that it had previously committed to purchase from Arc Home would be sold to third parties. The Company net settled its commitment to purchase these loans with Arc Home for $0.8 million, which represented the difference between the Company's committed price and the ultimate sale price, inclusive of costs to sell the loans. The settlement of these derivatives was recorded within the "Net realized gain/(loss)" and "Transaction related expenses" line items on the consolidated statement of operations.

Stock repurchase programs

On November 3, 2015, the Company’s Board of Directors authorized a stock repurchase program (the "2015 Repurchase Program") to repurchase up to $25.0 million of the Company's outstanding common stock. As of June 30, 2022 the $25.0 million maximum repurchase amount authorized under the 2015 Repurchase Program was fully utilized. The table below details the Company's share repurchases under the 2015 Repurchase Program during the nine months ended September 30, 2022:

(1) Based on trade date.

(2) Includes brokerage commissions and clearing fees.

On August 3, 2022, the Company's Board of Directors authorized a stock repurchase program (the "2022 Repurchase Program") to repurchase up to $15.0 million of the Company’s outstanding common stock on substantially the same terms as the 2015 Repurchase Program. The 2022 Repurchase Program does not have an expiration date and permits the Company to repurchase its shares through various methods, including open market repurchases, privately negotiated block transactions and Rule 10b5-1 plans. The Company may repurchase shares of its common stock from time to time in compliance with SEC regulations and other legal requirements. The extent to which the Company repurchases its shares, and the timing, manner, price, and amount of any such repurchases, will depend upon a variety of factors including market conditions and other corporate considerations as determined by the Company’s management, as well as the limits of the 2022 Repurchase Program and the Company's liquidity and business strategy. The 2022 Repurchase Program does not obligate the Company to acquire any particular amount of shares and may be modified or discontinued at any time. As of September 30, 2023, approximately $1.5 million of common stock remained authorized for future share repurchases under the 2022 Repurchase Program. The table

below details the Company's share repurchases under the 2022 Repurchase Program during the nine months ended September 30, 2023 and 2022:

(1) Based on trade date.

(2) Includes brokerage commissions and clearing fees.

On May 4, 2023, the Company's Board of Directors authorized a stock repurchase program (the "2023 Repurchase Program") to repurchase up to $15.0 million of the Company’s outstanding common stock on substantially the same terms as the 2022 Repurchase Program. As of September 30, 2023, the full $15.0 million authorized amount remains available for repurchase under the 2023 Repurchase Program. This authorization is in addition to the amount remaining under the 2022 Repurchase Program.

On February 22, 2021, the Company's Board of Directors authorized a stock repurchase program (the "Preferred Repurchase Program") pursuant to which the Company's Board of Directors granted a repurchase authorization to acquire shares of the Company's 8.25% Series A Cumulative Redeemable Preferred Stock ("Series A Preferred Stock"), 8.00% Series B Cumulative Redeemable Preferred Stock ("Series B Preferred Stock"), and 8.000% Series C Fixed-to-Floating Rate Cumulative Redeemable Preferred Stock ("Series C Preferred Stock") having an aggregate value of up to $20.0 million. No share repurchases under the Preferred Repurchase Program have been made since its authorization.

Shares of stock repurchased by the Company under any repurchase program, if any, will be cancelled and, until reissued by the Company, will be deemed to be authorized but unissued shares of its stock as required by Maryland law. The cost of the acquisition by the Company of shares of its own stock in excess of the aggregate par value of the shares first reduces additional paid-in capital, to the extent available, with any residual cost applied against retained earnings.

Equity distribution agreements

The Company has entered into an equity distribution agreement with each of Credit Suisse Securities (USA) LLC and JMP Securities LLC (collectively, the "Sales Agents"), which the Company refers to as the "Equity Distribution Agreements," pursuant to which the Company may sell up to $100.0 million aggregate offering price of shares of its common stock from time to time through the Sales Agents under the Securities Act of 1933. The Company did not issue any shares of common stock under the Equity Distribution Agreements during the three and nine months ended September 30, 2023 and 2022. Since inception of the program, the Company has issued approximately 2.2 million shares of common stock under the Equity Distribution Agreements for gross proceeds of $48.3 million.

Shelf registration statement

On May 7, 2021, the Company filed a new shelf registration statement, registering up to $1.0 billion of its securities, including capital stock (the "2021 Registration Statement"). The 2021 Registration Statement became effective on May 26, 2021 and will expire on May 28, 2024. Upon effectiveness of the 2021 Registration Statement, the Company's previous registration statement filed in 2018 was terminated.

The following table includes a summary of preferred stock issued and outstanding as of September 30, 2023 ($ and shares in thousands).

(1) The Company's Preferred Stock has a liquidation preference of $25.00 per share.

(3) The initial dividend rate for the Series C Preferred Stock, from and including the date of original issue to, but not including, September 17, 2024, is 8.000% per annum of the $25.00 per share liquidation preference. On and after September 17, 2024, dividends on the Series C Preferred Stock will accumulate at a percentage of the $25.00 liquidation preference equal to an annual floating rate of the then three-month LIBOR (or as replaced by the existing LIBOR cessation fallback language) plus a spread of 6.476% per annum.

(4) Dividends are payable quarterly in arrears on the 17th day of each March, June, September, and December and holders are entitled to receive cumulative cash dividends at the respective stated rate per annum before holders of common stock are entitled to receive any cash dividends.

The Company's Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock generally do not have any voting rights, subject to an exception in the event the Company fails to pay dividends on such stock for six or more quarterly periods (whether or not consecutive). Under such circumstances, holders of the Company's Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock voting together as a single class with the holders of all other classes or series of its preferred stock upon which like voting rights have been conferred and are exercisable and which are entitled to vote as a class with the Company's Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock will be entitled to vote to elect two additional directors to the Company’s Board of Directors until all unpaid dividends have been paid or declared and set apart for payment.

Results of Operations

Our operating results can be affected by a number of factors and primarily depend on the size and composition of our investment portfolio, the level of our net interest income, the fair value of our assets and the supply of, and demand for, our investments in residential mortgage loans in the marketplace, among other things, which can be impacted by unanticipated credit events, such as defaults, liquidations or delinquencies, experienced by borrowers whose residential mortgage loans are included in our investment portfolio and other unanticipated events in our markets. Our primary source of net income or loss available to common stockholders is our net interest income, inclusive of our cost or benefit of hedging, which represents the difference between the interest earned on our investment portfolio and the costs of financing and economic hedges in place on our investment portfolio, as well as any income or losses from our equity investments in affiliates.

Three Months Ended September 30, 2023 compared to the Three Months Ended September 30, 2022

The table below presents certain information from our consolidated statements of operations for the three months ended September 30, 2023 and 2022 (in thousands).

Interest income

Interest income is calculated using the effective interest method for our GAAP investment portfolio.

Interest income increased from the three months ended September 30, 2022 to the three months ended September 30, 2023 due to an increase in the size of our portfolio resulting from purchases of Non-Agency Loans and Agency-Eligible Loans during the period, as well as an increase in the weighted average yield. The following table presents a summary of the weighted average amortized cost and the weighted average yield on our GAAP investment portfolio for the three months ended September 30, 2023 and 2022 ($ in millions).

47

Interest expense

Interest expense is calculated based on the actual financing rate and the outstanding financing balance, inclusive of our financing arrangements and securitized debt, on our GAAP investment portfolio.

Interest expense increased from the three months ended September 30, 2022 to the three months ended September 30, 2023 due to an increase in the weighted average financing rate during the period resulting from increased interest rates and an increase in the amount of financing on our GAAP investment portfolio primarily resulting from the issuance of securitized debt. The following table presents a summary of the weighted average financing balance and the weighted average financing rate on our GAAP investment portfolio for the three months ended September 30, 2023 and 2022 ($ in millions).

Net interest component of interest rate swaps

Net interest component of interest rate swaps represents the net interest income received or expense paid on our interest rate swaps.

We recorded income on the net interest component of interest rate swaps during the three months ended September 30, 2023 as a result of our swap portfolio being in a net receive position during the entire period, compared with an expense for the three months ended September 30, 2022 as a result of our swap portfolio being in a net pay position during part of the period. The following table presents a summary of our interest rate swap portfolio as of September 30, 2023 and 2022 ($ in millions).

Net realized gain/(loss)

The following table presents a summary of Net realized gain/(loss) for the three months ended September 30, 2023 and 2022 (in thousands). The realized gain during the three months ended September 30, 2023 was driven by unwinding pay-fix, receive-variable interest rate swaps which were previously held at unrealized gains as a result of rising interest rates.

48

Net unrealized gain/(loss)

The following table presents a summary of net unrealized gain/(loss) for the three months ended September 30, 2023 and 2022 (in thousands). During the three months ended September 30, 2023, unrealized losses on residential mortgage loans and real estate securities and unrealized gains on securitized debt were primarily the result of rising interest rates during the period.

Management fee to affiliate

Our management fee is based upon a percentage of our Stockholders’ Equity. See the "Contractual obligations" section of this Item 2 for further detail on the calculation of our management fee and for the definition of Stockholders’ Equity. Management fees remained relatively consistent from the three months ended September 30, 2022 to the three months ended September 30, 2023.

Non-investment related expenses

Non-investment related expenses are primarily comprised of professional fees, directors’ and officers’ ("D&O") insurance, directors’ compensation, and certain non-investment related expenses reimbursable to our Manager or its affiliates. We are required to reimburse our Manager or its affiliates for operating expenses incurred by our Manager or its affiliates on our behalf, including certain compensation expenses and other expenses relating to legal, accounting, and other services. Refer to the "Contractual obligations" section below for more detail on certain expenses reimbursable to our Manager or its affiliates.

The following table presents a summary of our investment related expenses for the three months ended September 30, 2023 and 2022 (in thousands).

Transaction related expenses

On August 8, 2023, we entered into a Merger Agreement with WMC and, as a result, we have incurred certain expenses related to the pending Merger during the current period. Transaction related expenses increased from the three months ended September 30, 2022 to the three months ended September 30, 2023 primarily due to $4.9 million of expenses recorded related to the pending Merger with WMC, which includes the $3.0 million TPT Termination Fee we paid to TPT on WMC's behalf in connection with its termination of the TPT Merger Agreement.

Equity in earnings/(loss) from affiliates

Net realized gain/(loss)

The following table presents a summary of Net realized gain/(loss) for the nine months ended September 30, 2023 and 2022 (in thousands). The realized gain during the nine months ended September 30, 2023 was driven by unwinding pay-fix, receive-variable interest rate swaps which were previously held at unrealized gains as a result of rising interest rates.

53

Net unrealized gain/(loss)

The following table presents a summary of net unrealized gain/(loss) for the nine months ended September 30, 2023 and 2022 (in thousands). During the nine months ended September 30, 2023, unrealized losses on residential mortgage loans and real estate securities and unrealized gains on securitized debt were primarily the result of rising interest rates during the period. The unrealized losses recorded on derivatives for the nine months ended September 30, 2023 primarily represent the reclassification of unrealized gains to realized gains related to unwinding interest rate swaps during the period.

Management fee to affiliate

Our management fee is based upon a percentage of our Stockholders’ Equity. See the "Contractual obligations" section of this Item 2 for further detail on the calculation of our management fee and for the definition of Stockholders’ Equity.

Transaction related expenses

Transaction related expenses are expenses typically associated with purchasing and securitizing residential mortgage loans as well as certain other transaction and performance related fees associated with assets we invest in.

Transaction related expenses decreased from the nine months ended September 30, 2022 to the nine months ended September 30, 2023 primarily due to less upfront expenses associated with securitizations. We completed seven securitizations during the nine months ended September 30, 2022 and three securitizations during the nine months ended September 30, 2023. This was offset by $4.9 million of expenses recorded during the nine months ended September 30, 2023 related to the pending Merger with WMC, which includes the $3.0 million TPT Termination Fee we paid to TPT on WMC's behalf in connection with its termination of the TPT Merger Agreement.

Earnings Available for Distribution

One of our objectives is to generate net income from net interest margin on the portfolio, and management uses Earnings Available for Distribution ("EAD"), as one of several metrics, to help measure our performance against this objective. Management believes that this non-GAAP measure, when considered with our GAAP financial statements, provides supplemental information useful for investors to help evaluate our financial performance. However, management also believes that our definition of EAD has important limitations as it does not include certain earnings or losses our management team considers in evaluating our financial performance. Our presentation of EAD may not be comparable to similarly-titled measures of other companies, who may use different calculations. This non-GAAP measure should not be considered a substitute for, or superior to, Net Income/(loss) available to common stockholders or Net income/(loss) per diluted common share calculated in accordance with GAAP. Our GAAP financial results and the reconciliations from these results should be carefully evaluated.

We define EAD, a non-GAAP financial measure, as Net Income/(loss) available to common stockholders excluding (i) (a) unrealized gains/(losses) on loans, real estate securities, derivatives and other investments, inclusive of our investment in AG Arc, and (b) net realized gains/(losses) on the sale or termination of such instruments, (ii) any transaction related expenses incurred in connection with the acquisition, disposition, or securitization of our investments as well as transaction related expenses incurred in connection with the pending Merger with WMC, (iii) accrued deal-related performance fees payable to third party operators to the extent the primary component of the accrual relates to items that are excluded from EAD, such as unrealized and realized gains/(losses), (iv) realized and unrealized changes in the fair value of Arc Home's net mortgage servicing rights and the derivatives intended to offset changes in the fair value of those net mortgage servicing rights, (v) deferred taxes recognized at our taxable REIT subsidiaries, if any, and (vi) any gains/(losses) associated with exchange transactions on our common and preferred stock. Items (i) through (vi) above include any amount related to those items held in

56

affiliated entities. Management considers the transaction related expenses referenced in (ii) above to be similar to realized losses incurred at the acquisition, disposition, or securitization of an asset and does not view them as being part of its core operations. Management views the exclusion described in (iv) above to be consistent with how it calculates EAD on the remainder of its portfolio. Management excludes all deferred taxes because it believes deferred taxes are not representative of current operations. EAD includes the net interest income and other income earned on our investments on a yield adjusted basis, including TBA dollar roll income/(loss) or any other investment activity that may earn or pay net interest or its economic equivalent.

A reconciliation of "Net Income/(loss) available to common stockholders" to EAD for the three and nine months ended September 30, 2023 and 2022 is set forth below (in thousands, except per share data).

(1) For the three months ended September 30, 2023 and 2022, total transaction related expenses and deal related performance fees included $7.6 million and $5.3 million, respectively, recorded within the "Transaction related expenses" line item and $9.4 thousand and $0.2 million, respectively, recorded within the "Interest expense" line item, which relates to the amortization of deferred financing costs. For the nine months ended September 30, 2023 and 2022, total transaction related expenses and deal related performance fees included $9.7 million and $14.9 million, respectively, recorded within the "Transaction related expenses" line item and $0.2 million and $0.7 million, respectively, recorded within the "Interest expense" line item, which relates to the amortization of deferred financing costs.

(2) For the three months ended September 30, 2023 and 2022, $0.4 million or $0.02 per share and $2.4 million or $0.11 per share, respectively; and for the nine months ended September 30, 2023 and 2022, $1.2 million or $0.06 per share and $9.2 million or $0.40 per share, respectively, of realized and unrealized changes in the fair value of Arc Home's net mortgage servicing rights and corresponding derivatives were excluded from EAD, net of deferred tax expense or benefit. Additionally, for the three months ended September 30, 2023 and 2022, $(1.9) million or $(0.09) per share and $(1.2) million or $(0.05) per share, respectively; and for the nine months ended September 30, 2023 and 2022, $(1.7) million or $(0.08) per share and $(6.4) million or $(0.28) per share, respectively, of unrealized changes in the fair value of our investment in Arc Home were excluded from EAD.

(3) EAD recognized by AG Arc does not include our portion of gains recorded by Arc Home in connection with the sale of residential mortgage loans to us. For the three months ended September 30, 2023 and 2022, we eliminated $0.8 million or $0.04 per share and $1.8 million or $0.08 per share, respectively; and for the nine months ended September 30, 2023 and 2022, we eliminated $1.1 million or $0.06 per share and $5.9 million or $0.25 per share, respectively, of intra-entity profits recognized by Arc Home, and also decreased the cost basis of the underlying loans we purchased by the same amount.

Investment activities

Investment activities

We aim to allocate capital to investment opportunities with attractive risk/return profiles in our target asset classes. Our investment activities primarily include acquiring and securitizing newly-originated residential mortgage loans. We finance our acquired loans through various financing lines on a short-term basis and securitize the loans to obtain long-term, non-recourse, non-mark-to-market financing as market conditions permit. We may also invest in Agency RMBS to utilize excess liquidity. Our investment and capital allocation decisions depend on prevailing market conditions and compliance with Investment Company Act and REIT tests, among other factors, and may change over time in response to opportunities available in different economic and capital market environments. As a result, in reacting to market conditions and taking into account a variety of

57

other factors, including liquidity, duration, and interest rate expectations, the mix of our assets changes over time as we deploy capital. We actively evaluate our investments based on factors including, among others, the characteristics of the underlying collateral, geography, expected return, expected future prepayment trends, supply of and demand for our investments, costs of financing, costs of hedging, expected future interest rate volatility, and the overall shape of the U.S. Treasury and interest rate swap yield curves.

Net interest margin and leverage ratio

Net interest margin and leverage ratio are metrics that management believes should be considered when evaluating the performance of our investment portfolio.

GAAP net interest margin and non-GAAP net interest margin, a non-GAAP financial measure, are calculated by subtracting the weighted average cost of funds from the weighted average yield for our GAAP investment portfolio and our investment portfolio, respectively. The weighted average yield represents an effective interest rate on our cost basis, which utilizes all estimates of future cash flows and adjusts for actual prepayment and cash flow activity as of quarter-end. The calculation of weighted average yield is weighted on fair value at quarter-end. The weighted average cost of funds is the sum of the weighted average funding costs on total financing arrangements outstanding at quarter-end, including all non-recourse financing arrangements, and our weighted average hedging cost or benefit, which is the weighted average of the net pay or receive rates on our interest rate swaps. GAAP and non-GAAP cost of funds are weighted by the outstanding financing arrangements on our GAAP investment portfolio and our investment portfolio, respectively, and the fair value of securitized debt at quarter-end.

Our leverage ratio is determined by our portfolio mix as well as many additional factors, including the liquidity of our portfolio, the availability and price of our financing, the available capacity to finance our assets, and anticipated regulatory developments. See the "Financing activities" section below for more detail on our leverage ratio.

Residential mortgage loans

See Note 3 to the "Notes to Consolidated Financial Statements (unaudited)" for information on credit quality and a breakout of geographic concentration of credit risk within loans we include in the "Securitized residential mortgage loans, at fair value," "Residential mortgage loans, at fair value," and "Residential mortgage loans held for sale, at fair value" line items on our consolidated balance sheets.

Securitized Non-Agency Loans

As noted above, our investment activities primarily include acquiring and securitizing newly-originated residential mortgage loans. These securitization trusts ("Non-Agency VIEs") are collateralized by Non-Agency and Agency-Eligible Loans.

In each securitization transaction, we transfer a pool of loans to a wholly-owned subsidiary and the loans are deposited into a newly created securitization trust. The securitization trust issues various classes of mortgage pass-through certificates backed by the cash flows from the underlying residential mortgage loans (the "Certificates"). When we sponsor a residential mortgage loan securitization, we are generally required to retain at least 5% of the fair value of the Certificates issued in the securitization ("Risk Retention Rules"). We can retain either an "eligible vertical interest" (which consists of at least 5% of each class of securities issued in the securitization), an "eligible horizontal residual interest" (which is the most subordinate class of securities with a fair value of at least 5% of the aggregate credit risk) or a combination of both totaling 5% (the "Required Credit Risk"). In order to comply with the Risk Retention Rules in each securitization transaction, we generally purchase the most subordinated classes of Certificates and the excess cash flow Certificates. We also purchase the Certificates entitled to excess servicing fees and may purchase other Certificates issued by the securitization trust, while typically selling the senior classes of Certificates to unrelated third parties.

If we are determined to be the primary beneficiary of these securitization transactions, we consolidate the respective VIE created to facilitate the transaction and record "Securitized residential mortgage loans" and "Securitized debt" on the consolidated balance sheets in accordance with U.S. GAAP. However, as noted above, our equity at risk represents certain Certificates from each securitization which we retain.

The following table summarizes our Securitized residential mortgage loans and Securitized debt, as well as the economic interest on retained Certificates related to our Non-Agency VIEs (in thousands).

(1) Interest Only have no principal balances and bear interest based on a notional balance. The notional balance is used solely to determine interest distributions on the interest only classes of securities. As of September 30, 2023 and December 31, 2022, the Securitized debt in Non-Agency VIEs line item includes interest only classes with notional balances of $135.7 million and $144.3 million, respectively. As of September 30, 2023 and December 31, 2022, the notional balance on Interest Only / Excess Servicing Bonds was $9.3 billion and $8.0 billion, respectively.

(2) Represents the fair value of real estate owned within Non-Agency VIEs. We record real estate owned at the lower of cost or fair value less estimated costs to sell. As of September 30, 2023, we recorded real estate owned within our Non-Agency VIEs at $1.2 million.

(3) Maximum loss exposure from our involvement with VIEs pertains to the fair value of the Certificates retained from the VIEs. We have no obligation to provide any other explicit or implicit support to the securitization trusts.

(4) As of September 30, 2023 and December 31, 2022, our equity at risk included bonds with a fair value of $257.6 million and $215.1 million, respectively, held in order to comply with Risk Retention Rules. We are generally required to hold the Required Credit Risk until the later of (i) the fifth anniversary of the securitization closing date and (ii) the date on which the aggregate unpaid principal balance of the mortgage loans has been reduced to 25% of the aggregate unpaid principal balance of the mortgage loans as of the securitization closing date, but no longer than the seventh anniversary of the closing date.

(5) As of September 30, 2023 and December 31, 2022, a portion of our equity at risk included bonds exposed to the first loss of the securitization with a fair value of $87.5 million and $84.7 million, respectively.

(6) Excludes net other asset/(liabilities) held within the VIEs of $7.2 million and $4.4 million as of September 30, 2023 and December 31, 2022, respectively.

(7) As the sponsor and depositor of each securitization, we may purchase all of the outstanding Certificates (an "Optional Redemption") following the earlier of (1) an applicable anniversary date (typically two or three years) of the respective securitization or (2) the date at which the unpaid principal balance of the applicable collateral has declined below a certain percentage (typically 10% to 30%) of the principal balance originally contributed to the securitization. As of September 30, 2023, there was one securitization with an unpaid principal balance of $125.7 million that met the criteria for an Optional Redemption. As of December 31, 2022, there were no securitizations which met the criteria for an Optional Redemption.
