Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Chimera Investment Corporation, or the Company, was organized in Maryland on June 1, 2007. The Company commenced operations on November 21, 2007 when it completed its initial public offering. The Company elected to be taxed as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, and regulations promulgated thereunder, or the Code. The Company is an internally managed REIT that is primarily engaged, through its subsidiaries, in the business of investing in a diversified portfolio of mortgage assets, including residential mortgage loans, Agency RMBS, Non-Agency RMBS, Agency CMBS, and other real estate-related assets. The following defines certain of the commonly used terms in this Quarterly Report on Form 10-Q: Agency refers to a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government, such as Ginnie Mae; MBS refers to mortgage-backed securities secured by pools of residential or commercial mortgage loans; RMBS refers to mortgage-backed securities secured by pools of residential mortgage loans; CMBS refers to mortgage-backed securities secured by pools of commercial mortgage loans; Agency RMBS and Agency CMBS refer to MBS that are secured by pools of residential and commercial mortgage loans, respectively, and are issued or guaranteed by an Agency; ABS refers to asset-backed securities; Agency MBS refers to MBS that are issued or guaranteed by an Agency and includes Agency RMBS and Agency CMBS collectively; Agency CMO refers to collateralized mortgage obligations guaranteed by an Agency and are included in Agency RMBS; Non-Agency RMBS refers to residential MBS that are not guaranteed by any agency of the U.S. Government or any Agency; IO refers to Interest-only securities. The Company conducts its operations through various subsidiaries including subsidiaries it treats as taxable REIT subsidiaries, or TRSs. 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. The Company currently has twelve wholly-owned direct subsidiaries: Chimera RMBS Whole Pool LLC and Chimera RMBS LLC formed in June 2009; CIM Trading Company LLC, or CIM Trading, formed in July 2010; Chimera Funding TRS LLC, or CIM Funding TRS, a TRS formed in October 2013; Chimera CMBS Whole Pool LLC and Chimera RMBS Securities LLC formed in March 2015; Chimera RR Holding LLC formed in April 2016; Anacostia LLC, a TRS formed in June 2018; NYH Funding LLC, a TRS formed in May 2019; Kali 2020 Holdings LLC formed in May 2020; Varuna Capital Partners LLC formed in September 2020; and Aarna Holdings LLC formed in November 2020. During 2022, the Company exchanged its interest in Kah Capital Management, LLC for an interest in Kah Capital Holdings, LLC, which is accounted for as an equity method investment in other assets on the Statement of Financial Condition at September 30, 2024. Kah Capital Holdings, LLC is the parent of Kah Capital Management, LLC. The Company paid $128 thousand and $398 thousand for mortgage asset servicing oversight fees to Kah Capital Management during the quarter and nine months ended September 30, 2024, respectively. The Company paid $150 thousand and $445 thousand for mortgage asset servicing oversight fees to Kah Capital Management during the quarter and nine months ended September 30, 2023. These fees are reported within Other Expenses on the Consolidated Statement of Operations. The Company has made a $75 million capital commitment to a fund managed by Kah Capital Management, LLC. During the quarter ended September 30, 2024 the Company did not fund any amounts towards that commitment. During the nine months ended September 30, 2024 the Company funded an additional $10 million towards that commitment, which brought its total funding to $56 million, leaving an unfunded commitment of $19 million. The Company's investment in this fund is accounted for as an equity method investment in other assets on the Consolidated Statement of Financial Condition.

Accounting Policies [Abstract]
Summary of the Significant Accounting Policies	Summary of the Significant Accounting Policies (a) Basis of Presentation and Consolidation The accompanying consolidated financial statements and related notes of the Company have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP. In the opinion of the Company, all normal and recurring adjustments considered necessary for a fair presentation of its financial position, results of operations and cash flows have been included. Investment transactions are recorded on the trade date. Certain prior year amounts have been reclassified to conform to the current year’s presentation. All per share amounts, common shares outstanding and restricted shares for all periods presented reflect the Company's 1-for-3 reverse stock split, which was effective after the close of trading on May 21, 2024. The consolidated financial statements include the Company’s accounts, the accounts of its wholly-owned subsidiaries, and variable interest entities, or VIEs, in which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. The Company uses securitization trusts considered to be VIEs in its securitization transactions. VIEs are defined as entities in which equity investors (i) do not have the characteristics of a controlling financial interest, or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The entity that consolidates a VIE is known as its primary beneficiary and is generally the entity with (i) the power to direct the activities that most significantly impact the VIEs’ economic performance, and (ii) the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could 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 VIEs’ economic performance may be determined by an entity’s involvement with the design and structure of the VIE. The trusts are structured as entities 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 risks associated with being the sponsor and depositor of and the seller, directly or indirectly to, the securitizations 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 of the VIEs that most significantly impact the VIEs’ economic performance, or power, such as rights to replace the servicer without cause, or the Company was determined to have power in connection with its involvement with the structure and design of the VIE. The Company’s interest in the assets held by these securitization vehicles, which are consolidated on the Company’s Consolidated Statements of Financial Condition, is restricted by the structural provisions of these trusts, and a recovery of the Company’s investment in the vehicles will be limited by each entity’s distribution provisions. Generally, the securities retained by the Company are the most subordinate in the capital structure, which means those securities receive distributions after the senior securities have been paid. The liabilities of the securitization vehicles, which are also consolidated on the Company’s Consolidated Statements of Financial Condition, 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 residential mortgage-backed securities, or RMBS, or residential mortgage loans. See Notes 3, 4 and 9 for further discussion of the characteristics of the securities and loans in the Company’s portfolio. (b) Statements of Financial Condition Presentation The Company’s Consolidated Statements of Financial Condition include both the Company’s direct assets and liabilities and the assets and liabilities of consolidated securitization vehicles. Retained beneficial interests of the consolidated securitization vehicles are eliminated in consolidation. Assets of each consolidated VIE can only be used to satisfy the obligations of that VIE, and the liabilities of consolidated VIEs are non-recourse to the Company. The Company is not obligated to provide, nor does it intend to provide, any financial support to these consolidated securitization vehicles. The notes to the consolidated financial statements describe the Company’s assets and liabilities including the assets and liabilities of consolidated securitization vehicles. See Note 9 for additional information related to the Company’s investments in consolidated securitization vehicles. (c) Net Income per Share The Company calculates basic net income per share by dividing net income for the period by the basic weighted-average shares of its common stock outstanding for that period. Diluted net income per share takes into account the effect of dilutive instruments such as unvested restricted stock units. All per share amounts, common shares outstanding and restricted shares for all periods presented reflect the Company's 1-for-3 reverse stock split, which was effective after the close of trading on May 21, 2024. (d) Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although the Company’s estimates contemplate current conditions and how it expects them to change in the future, it is reasonably possible that actual conditions could be materially different than anticipated in those estimates, which could have a material adverse impact on the Company’s results of operations and its financial condition. The Company has made significant estimates including in accounting for income recognition on Agency MBS, Non-Agency RMBS, IO MBS (Note 3) and residential mortgage loans (Note 4), valuation of Agency MBS and Non-Agency RMBS (Notes 3 and 5), residential mortgage loans (Notes 4 and 5), secured financing agreements (Notes 5 and 6), and securitized debt (Notes 5 and 7). Actual results could differ materially from those estimates. (e) Long Term Debt The Company's Long Term Debt is comprised of unsecured senior notes. Unsecured senior notes are carried at their unpaid principal balance net of any unamortized deferred issuance costs. Interest on the notes is payable quarterly until such time the notes mature. Any debt discounts or premiums are reported as an adjustment to the carrying amount of the debt liability and amortized into interest expense using the effective interest method. Deferred debt issuance costs are expenses associated with the issuance of long-term debt. These expenses typically include underwriting, legal, accounting, and other fees. Deferred debt issuance costs are included in the carrying value of the related long-term debt issued and are amortized as an adjustment to interest expense using the effective interest method, based upon the actual and estimated repayment schedules of the related long-term debt issued. (f) 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, 2023, other than the significant accounting policies discussed below. Fair Value Disclosure A complete discussion of the methodology utilized by the Company to estimate the fair value of its financial instruments is included in Note 5 to these consolidated financial statements. Income Taxes The Company does not have any material unrecognized tax positions that would affect its financial statements or require disclosure. No accruals for penalties and interest were necessary as of September 30, 2024 or December 31, 2023. (g) Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280); Improvements to Reportable Segment Disclosures. This standard requires public companies to disclose information about their reportable segments' significant expenses on an interim and annual basis to provide more transparency about the expenses they incur from revenue generating business units. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not expect the adoption of the new standard to have a material effect on its Consolidated Financial Statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740); Improvements to Income Tax Disclosures. this standard require entities to provide additional information about federal, state and foreign incomes taxes and reconciling items in the rate reconciliation table, and to disclose further disaggregation of income taxes paid (net of refunds received) by federal (national), state and foreign taxes by jurisdiction. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The guidance should be applied prospectively, but entities have the option to apply it retrospectively for each period presented. The Company does not expect the adoption of the new standard to have a material effect on its Consolidated Financial Statements.

With respect to RMBS held by consolidated VIEs, the ability of any entity to cause the sale by the VIE prior to the maturity of these RMBS is either expressly prohibited, not probable, or is limited to specified events of default, none of which have occurred as of September 30, 2024. The Company h ad no gross unrealized losses on its Agency MBS (excluding Agency MBS which are reported at fair value with ch anges in fair value recorded in earnings) as of September 30, 2024. The Company h ad $23 thousand unrealized losses on its Agency MBS as of December 31, 2023. Given the inherent credit quality of Agency MBS, the Company does not consider any of the current impairments on its Agency MBS to be credit related. In evaluating whether it is more likely than not that it will be required to sell any impaired security before its anticipated recovery, which may be at their maturity, the Company considers the significance of each investment, the amount of impairment, the projected future performance of such impaired securities, as well as the Company’s current and anticipated leverage capacity and liquidity position. Based on this analysis, the Company determined that at September 30, 2024 and December 31, 2023 unrealized losses on its Agency MBS were temporary. Gross unrealized losses on the Company’s Non-Agency RMBS (excluding Non-Agency RMBS which are reported at fair value with changes in fair value recorded in earnings), net of any allowance for credit losses, were $12 million and $18 million, at September 30, 2024 and December 31, 2023, respectively. After evaluating the securities and recording any allowance for credit losses, the Company concluded that the remaining unrealized losses reflected above were non-credit related and would be recovered from the securities' estimated future cash flows. The Company considered a number of factors in reaching this conclusion, including that it did not intend to sell the securities, it was not considered more likely than not that it would be required to sell the securities prior to recovering the amortized cost, and there were no material credit events that would have caused the Company to otherwise conclude that it would not recover the amortized cost. The allowance for credit losses are calculated by comparing the estimated future cash flows of each security discounted at the yield determined as of the initial acquisition date or, if since revised, as of the last date previously revised, to the net amortized cost basis. Significant judgment is used in projecting cash flows for Non-Agency RMBS. The Company has reviewed its Non-Agency RMBS that are in an unrealized loss position to identify those securities with losses that are credit related based on an assessment of changes in cash flows expected to be collected for such RMBS, which considers recent bond performance and expected future performance of the underlying collateral. A summary of the credit losses allowance on available-for-sale securities for the quarters and nine months ended September 30, 2024 and 2023 is presented below. For the Quarter Ended For the Nine Months Ended September 30, 2024 September 30, 2023 September 30, 2024 September 30, 2023 (dollars in thousands) (dollars in thousands) Beginning allowance for credit losses $ 23,591 $ 13,013 $ 18,560 $ 7,188 Additions to the allowance for credit losses on securities for which credit losses were not previously recorded 6 415 1,595 1,514 Allowance on purchased financial assets with credit deterioration — — — — Reductions for the securities sold during the period — — — — Increase/(decrease) on securities with an allowance in the prior period (1,440) 2,802 1,810 10,355 Write-offs charged against the allowance (110) — (412) (2,860) Recoveries of amounts previously written off 1,902 — 2,396 33 Ending allowance for credit losses $ 23,949 $ 16,230 $ 23,949 $ 16,230 The following table presents significant credit quality indicators used for the credit loss allowance on our Non-Agency RMBS investments as of September 30, 2024 and December 31, 2023.

In addition, certain Non-Agency RMBS positions now have higher unrealized losses and resulted in the recognition of an allowance for credit losses which was previously limited by unrealized gains on these investments.

Investments, Debt and Equity Securities [Abstract]
Loans Held for Investment	Loans Held for Investment The Loans held for investment are comprised primarily of loans collateralized by seasoned reperforming residential mortgages. Additionally, it includes jumbo prime loans, investor loans and business purpose loans. The investor loans are loans to individuals securing non-primary residences as well as to individuals or businesses who rent out the residential properties secured by such loans. The Company purchases qualified mortgages, or QM, and non-qualified mortgages, or Non-QM, investor loans and securitizes them under its loan securitization program. The business purpose loans are loans to businesses that are secured by real property which will be renovated by the borrower. The business purpose loans tend to be short duration, often less than one year, and generally the coupon rate is higher than residential mortgage loans. At September 30, 2024 and December 31, 2023, all Loans held for investment are carried at fair value. See Note 5 for a discussion on how the Company determines the fair values of the Loans held for investment. As changes in the fair value of these loans are reflected in earnings, the Company does not estimate or record a loan loss provision. The total amortized cost of the Company's Loans held for investment was $11.3 billion and $11.8 billion as of September 30, 2024 and December 31, 2023, respectively. The total unpaid principal balance of the Company's Loans held for investment was $11.6 billion and $12.0 billion as of September 30, 2024 and December 31, 2023, respectively. The following table provides a summary of the changes in the carrying value of Loans held for investment at fair value at September 30, 2024 and December 31, 2023: For the Nine Months Ended For the Year Ended September 30, 2024 December 31, 2023 (dollars in thousands) Balance, beginning of period $ 11,397,046 $ 11,359,236 Purchases 579,993 1,421,537 Principal paydowns (964,508) (1,417,787) Sales and settlements (96,737) (246) Net periodic accretion (amortization) (37,660) (51,005) Change in fair value 405,641 85,311 Balance, end of period $ 11,283,775 $ 11,397,046 The primary cause of the change in fair value is due to market demand, interest rates and changes in credit risk of mortgage loans. The Company did not retain any beneficial interests on loan sales during the quarter ended September 30, 2024 and year ended December 31, 2023.

Fair Value Measurements

Fair Value Measurements	9 Months Ended
Fair Value Measurements	Sep. 30, 2024
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company applies fair value guidance in accordance with GAAP to account for its financial instruments. The Company categorizes its financial instruments, based on the priority of the inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the financial instruments fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair value measurement of the instrument. Financial assets and liabilities recorded at fair value on the Consolidated Statements of Financial Condition or disclosed in the related notes are categorized based on the inputs to the valuation techniques as follows: Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets and liabilities in active markets. Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3 – inputs to the valuation methodology are unobservable and significant to fair value. Fair value measurements categorized within Level 3 are sensitive to changes in the assumptions or methodology used to determine fair value and such changes could result in a significant increase or decrease in the fair value. Any changes to the valuation methodology are reviewed by the Company to ensure the changes are appropriate. As markets and products evolve and the pricing for certain products becomes more transparent, the Company will continue to refine its valuation methodologies. The methodology utilized by the Company for the periods presented is unchanged. The methods used to produce a fair value calculation may not be indicative of net realizable value or reflective of future fair values. Furthermore, the Company believes its valuation methods are appropriate and consistent with other market participants. Using different methodologies, or assumptions, to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. The Company uses inputs that are current as of the measurement date, which may include periods of market dislocation, during which price transparency may be reduced. The Company determines the fair values of its investments using internally developed processes and validates them using a third-party pricing service. During times of market dislocation, the observability of prices and inputs can be difficult for certain investments. If the third-party pricing service is unable to provide a price for an asset, or if the price provided by them is deemed unreliable by the Company, then the asset will be valued at its fair value as determined by the Company without validation to third-party pricing. Illiquid investments typically experience greater price volatility as an active market does not exist. Observability of prices and inputs can vary significantly from period to period and may cause instruments to change classifications within the three level hierarchy. A description of the methodologies utilized by the Company to estimate the fair value of its financial instruments by instrument class follows: Agency MBS and Non-Agency RMBS The Company determines the fair value of all of its investment securities based on discounted cash flows utilizing an internal pricing model that incorporates factors such as coupon, prepayment speeds, loan size, collateral composition, borrower characteristics, expected interest rates, life caps, periodic caps, reset dates, collateral seasoning, delinquency, expected losses, expected default severity, credit enhancement, and other pertinent factors. To corroborate that the estimates of fair values generated by these internal models are reflective of current market prices, the Company compares the fair values generated by the model to non-binding independent prices provided by an independent third-party pricing service. For certain highly liquid asset classes, such as Agency fixed-rate pass-through bonds, the Company’s valuations are also compared to quoted prices for To-Be-Announced, or TBA, securities. Each quarter, the Company develops thresholds generally using market factors or other assumptions, as appropriate. If internally developed model prices differ from the independent third-party prices by greater than these thresholds for the period, the Company conducts a further review, both internally and with the third-party pricing service of the prices of such securities. First, the Company obtains the inputs used by the third-party pricing service and compares them to the Company’s inputs. The Company then updates its own inputs if the Company determines the third-party pricing inputs more accurately reflect the current market environment. If the Company believes that its internally developed inputs more accurately reflect the current market environment, it will request that the third-party pricing service review market factors that may not have been considered by the third-party pricing service and provide updated prices. The Company reconciles and resolves all pricing differences in excess of the thresholds before a final price is established. At September 30, 2024, seven investment holdings with internally developed fair values of $53 million had a difference between the model generated prices and third-party prices provided in excess of the thresholds for the period. The internally developed prices were $1 million higher than the third-party prices provided of $52 million. After review and discussion, the Company affirmed and valued the investments at the higher internally developed prices. No other differences were noted at September 30, 2024 in excess of the thresholds for the period. At December 31, 2023, one investment holding with an internally developed fair value of $6 million had a difference between the model generated price and third-party price provided in excess of the threshold for the period. The internally developed price was $1 million higher, in the aggregate, than the third-party prices provided of $5 million. After review and discussion, the Company affirmed and valued the investment at the higher internally developed price. No other differences were noted at December 31, 2023 in excess of the thresholds for the period. The Company’s estimate of prepayment, default and severity curves all involve judgment and assumptions that are deemed to be significant to the fair value measurement process. This subjective estimation process renders the Non-Agency RMBS fair value estimates as Level 3 in the fair value hierarchy. As the fair values of Agency MBS are more observable, these investments are classified as Level 2 in the fair value hierarchy. Loans Held for Investment Loans held for investment is comprised primarily of seasoned reperforming residential mortgage loans. Loans held for investment also include jumbo prime, investor owned and business purpose loans. Loans consisting of seasoned reperforming residential mortgage loans, jumbo prime loans and investor loans: The Company estimates the fair value of its Loans held for investment consisting of seasoned reperforming residential mortgage loans, jumbo prime loans and investor loans on a loan by loan basis using an internally developed model which compares the loan held by the Company with a loan currently offered in the market. The loan price is adjusted in the model by considering the loan factors which would impact the value of a loan. These loan factors include loan coupon, FICO, loan-to-value ratios, delinquency history, owner occupancy, and property type, among other factors. A baseline is developed for each significant loan factor and adjusts the price up or down depending on how that factor for each specific loan compares to the baseline rate. Generally, the most significant impact on loan value is the loan coupon rate as compared to coupon rates currently available in the market and delinquency history. The Company also monitors market activity to identify trades which may be used to compare internally developed prices; however, as the portfolio of loans held at fair value is a seasoned reperforming pool of residential mortgage loans, comparable loan pools are not common or directly comparable. There are limited transactions in the marketplace to develop a comprehensive direct range of values. The Company reviews the fair values generated by the model to determine whether prices are reflective of the current market by corroborating its estimates of fair value by comparing the results to non-binding independent prices provided by an independent third-party pricing service for the loan portfolio. Each quarter the Company develops thresholds generally using market factors or other assumptions as appropriate. If the internally developed fair values of the loan pools differ from the independent third-party prices by greater than the threshold for the period, the Company highlights these differences for further review, both internally and with the third-party pricing service. The Company obtains certain inputs used by the third-party pricing service and evaluates them for reasonableness. Then the Company updates its own model if the Company determines the third-party pricing inputs more accurately reflect the current market environment or observed information from the third-party vendor. If the Company believes that its internally developed inputs more accurately reflect the current market environment, it will request that the third-party pricing service review market factors that may not have been considered by the third-party pricing service. The Company reconciles and resolves all pricing differences in excess of the thresholds before a final price is established. At September 30, 2024, one po ol with an internally developed fair value of $55 million had a difference between the model g enerated price and third-party price provided in excess of the threshold for the period. The internally developed price was $3 million higher than the third-party price provided of $52 million. After review and discussion, the Company affirmed and valued the investment at the higher internally developed price. No other differences were noted at September 30, 2024 in excess of the threshold for the period. At December 31, 2023, one loan pool with an internally developed fair value of $109 million had a difference between the model generated price and third-party price provided in excess of the threshold for the period. The internally developed price was $7 million higher than the third-party price provided of $102 million. After review and discussion, the Company affirmed and valued the investment at the higher internally developed price. No other differences were noted at December 31, 2023 in excess of the threshold for the period. The Company’s estimates of fair value of Loans held for investment involve judgment and assumptions that are deemed to be significant to the fair value measurement process, which renders the resulting fair value estimates Level 3 inputs in the fair value hierarchy. Business purpose loans: Business purpose loans are loans to businesses that are secured by real property which will be renovated by the borrower. Upon completion of the renovation the property will be either sold by the borrower or refinanced by the borrower who may subsequently sell or rent the property. Most, but not all, of the properties securing these loans are residential and a portion of the loan is used to cover renovation costs. The business purpose loans are included as a part of the Company's Loans held for investment portfolio and are carried at fair value with changes in fair value reflected in earnings. These loans tend to be short duration, often less than one year, and generally the coupon rate is higher than the Company's typical residential mortgage loans. As these loans are generally short-term in nature and there is an active market for these loans, the Company estimates fair value of the business purpose loans based on the recent purchase price of the loan, adjusted for observable market activity for similar assets offered in the market. Business purpose loans have a fair value of $233 million and $272 million as of September 30, 2024 and December 31, 2023, respectively. As the fair value prices of the business purpose loans are based on the recent trades of similar assets in an active market, the Company has classified them as Level 2 in the fair value hierarchy. Securitized Debt, collateralized by Loans Held for Investment The process for determining the fair value of securitized debt, collateralized by Loans held for investment is based on discounted cash flows utilizing an internal pricing model that incorporates factors such as coupon, prepayment speeds, loan size, collateral composition, borrower characteristics, expected interest rates, life caps, periodic caps, reset dates, collateral seasoning, delinquencies, expected losses, expected default severity, credit enhancement, and other pertinent factors. This process, including the review process, is consistent with the process used for Agency MBS and Non-Agency RMBS using internal models. For further discussion of the valuation process and benchmarking process, see Agency MBS and Non-Agency RMBS discussion herein. The primary cause of the change in fair value is due to market demand and changes in credit risk of mortgage loans. At September 30, 2024, four securitized debt collateralized by Loans held for investment position with an internally developed fair value of $224 million had a difference between the model generated price and third-party price provided in excess of the threshold for the period. The internally developed price was $12 million lower on a net basis than the third-party price provided of $236 million. After review and discussion, the Company affirmed and valued the securitized debt positions at the lower internally developed price . No other differences were noted at September 30, 2024 in excess of the threshold for the period. At December 31, 2023, four securitized debt collateralized by Loans held for investment positions with an internally developed fair value of $247 million had a difference between the model generated prices and third-party prices provided in excess of the threshold for the period. The internally developed prices were $9 million lower on a net basis than the third-party prices provided of $256 million. After review and discussion, the Company affirmed and valued the securitized debt positions at the lower internally developed prices. No other pricing differences were noted at December 31, 2023 in excess of the threshold for the period. The Company’s estimates of fair value of securitized debt, collateralized by Loans held for investment involve judgment and assumptions that are deemed to be significant to the fair value measurement process, which renders the resulting fair value estimates Level 3 inputs in the fair value hierarchy. Securitized Debt, collateralized by Non-Agency RMBS The Company carries securitized debt, collateralized by Non-Agency RMBS at the principal balance outstanding plus unamortized premiums, less unaccreted discounts recorded in connection with the financing of the loans or RMBS with third parties. For disclosure purposes, the Company estimates the fair value of securitized debt, collateralized by Non-Agency RMBS by estimating the future cash flows associated with the underlying assets collateralizing the secured debt outstanding. The Company models the fair value of each underlying asset by considering, among other items, the structure of the underlying security, coupon, servicer, delinquency, actual and expected defaults, actual and expected default severities, reset indices, and prepayment speeds in conjunction with market research for similar collateral performance and the Company's expectations of general economic conditions in the sector and other economic factors. This process, including the review process, is consistent with the process used for Agency MBS and Non-Agency RMBS using internal models. For further discussion of the valuation process and benchmarking process, see Agency MBS and Non-Agency RMBS discussion herein. The Company’s estimates of fair value of securitized debt, collateralized by Non-Agency RMBS involve judgment and assumptions that are deemed to be significant to the fair value measurement process, which renders the resulting fair value estimates Level 3 inputs in the fair value hierarchy.

For bi-lateral swaps, the Company determines the fair value based on the net present value of expected future cash flows on the swap. The Company uses an option pricing model to determine the fair value of its swaptions. For bi-lateral swaps and swaptions, the Company compares its own estimate of fair value with counterparty prices to evaluate for reasonableness. Both the clearing exchange and counter-party pricing quotes, incorporate common market pricing methods, including a spread measurement to the Treasury yield curve or interest rate swap curve as well as underlying characteristics of the particular contract. Interest rate swaps and swaptions are modeled by the Company by incorporating such factors as the term to maturity, swap curve, overnight index swap rates, and the payment rates on the fixed portion of the interest rate swaps. The Company has classified the characteristics used to determine the fair value of interest rate swaps and swaptions as Level 2 inputs in the fair value hierarchy. Treasury Futures The fair value of Treasury futures is determined by quoted market prices in an active market. The Company has classified the characteristics used to determine the fair value of Treasury futures as Level 1 inputs in the fair value hierarchy. Secured Financing Agreements Secured financing agreements are collateralized financing transactions utilized by the Company to acquire investment securities. For short term secured financing agreements and longer term floating rate secured financing agreements, the Company estimates fair value using the contractual obligation plus accrued interest payable. The Company has classified the characteristics used to determine the fair value of secured financing agreements as Level 2 inputs in the fair value hierarchy. Secured Financing Agreements, at fair value Fair value for certain secured financing agreements which are carried at fair value with changes in fair value reported in earnings are valued at the price that the Company would pay to transfer the liability to a market participant at the reporting date in an orderly transaction. The Company evaluates recent trades of financial liabilities made by the Company, which includes an element of non-performance risk, as well as changes in market interest rates to determine the fair value of the secured financing agreements. The primary factor in determining the fair value is the change in market interest rates from the transaction date of the secured financing agreements and the reporting date. As these rates are observable, the secured financing agreements are reported as Level 2 inputs in the fair value hierarchy. Short-term Financial Instruments The carrying value of cash and cash equivalents, accrued interest receivable, dividends payable, payable for investments purchased, and accrued interest payab le are considered to be a reasonable estimate of fair value due to the short term nature and low credit risk of these short-term financial instruments. Long term debt The fair value of the Company's Senior Unsecured Notes is based upon prices obtained from third-party pricing services or broker quotations and are classified as Level 2. Equity Method Investments The Company has made investments in entities or funds. For these investments where we have a non-controlling interest, but we are deemed to be able to exert significant influence over the affairs of these entities or funds, we utilize equity method of accounting. These investments are not carried at fair value. The carrying value of the Company's equity method investments is determined using cost accumulation method. The Company adjusts the carrying value of its equity method investments for its share of earnings or losses, dividends or return of capital on a quarterly basis. The fair value of equity method investments is based on the fund valuation received from the manager of the fund. The Company has classified the characteristics used to determine the fair value of equity method investments as Level 3 inputs in the fair value hierarchy. The equity method investments are included in Other assets on the Consolidated Statement of Financial Condition. The Company’s financial assets and liabilities carried at fair value on a recurring basis, including the level in the fair value hierarchy, at September 30, 2024 and December 31, 2023 are presented below.

The significant unobservable inputs used in the fair value measurement of the Company’s Non-Agency RMBS and securitized debt are the weighted average discount rates, prepayment rate, constant default rate, and the loss severity. Discount Rate The discount rate refers to the interest rate used in the discounted cash flow analysis to determine the present value of future cash flows. The discount rate takes into account not just the time value of money, but also the risk or uncertainty of future cash flows. An increased uncertainty of future cash flows results in a higher discount rate. The discount rate used to calculate the present value of the expected future cash flows is based on the discount rate implicit in the security as of the last measurement date. As discount rates move up, the values of the discounted cash flows are reduced. The discount rates applied to the expected cash flows to determine fair value are derived from a range of observable prices on securities backed by similar collateral. As the market becomes more or less liquid, the availability of these observable inputs will change. Prepayment Rate The prepayment rate specifies the percentage of the collateral balance that is expected to prepay at each point in the future. The prepayment rate is based on factors such as interest rates, loan-to-value ratio, debt-to-income ratio, and is scaled up or down to reflect recent collateral-specific prepayment experience as obtained from remittance reports and market data services. Constant Default Rate Constant default rate represents an annualized rate of default on a group of mortgages. The constant default rate, or CDR, represents the percentage of outstanding principal balances in the pool that are in default, which typically equates to the home being past 60-day and 90-day notices and in the foreclosure process. When default rates increase, expected cash flows on the underlying collateral decreases. When default rates decrease, expected cash flows on the underlying collateral increases. Default vectors are determined from the current “pipeline” of loans that are more than 30 days delinquent, in foreclosure, bankruptcy, or are REO. These delinquent loans determine the first 30 months of the default curve. Beyond month 30, the default curve transitions to a value that is reflective of a portion of the current delinquency pipeline. Loss Severity Loss severity rates reflect the amount of loss expected from a foreclosure and liquidation of the underlying collateral in the mortgage loan pool. When a mortgage loan is foreclosed the collateral is sold and the resulting proceeds are used to settle the outstanding obligation. In many circumstances, the proceeds from the sale do not fully repay the outstanding obligation. In these cases, a loss is incurred by the lender. Loss severity is used to predict how costly future losses are likely to be. An increase in loss severity results in a decrease in expected future cash flows. A decrease in loss severity results in an increase in expected future cash flows. The curve generated to reflect the Company’s expected loss severity is based on collateral-specific experience with consideration given to other mitigating collateral characteristics. Collateral characteristics such as loan size, loan-to-value, seasoning or loan age and geographic location of collateral also effect loss severity. Sensitivity of Significant Inputs – Non-Agency RMBS and securitized debt, collateralized by Loans held for investment Prepayment rates vary according to interest rates, the type of financial instrument, conditions in financial markets, and other factors, none of which can be predicted with any certainty. In general, when interest rates rise, it is relatively less attractive for borrowers to refinance their mortgage loans, and as a result, prepayment speeds tend to decrease. When interest rates fall, prepayment speeds tend to increase. For RMBS investments purchased at a premium, as prepayment rates increase, the amount of income the Company earns decreases as the purchase premium on the bonds amortizes faster than expected. Conversely, decreases in prepayment rates result in increased income and can extend the period over which the Company amortizes the purchase premium. For RMBS investments purchased at a discount, as prepayment rates increase, the amount of income the Company earns increases from the acceleration of the accretion of the purchase discount into interest income. Conversely, decreases in prepayment rates result in decreased income as the accretion of the purchase discount into interest income occurs over a longer period. For securitized debt carried at fair value issued at a premium, as prepayment rates increase, the amount of interest expense the Company recognizes decreases as the issued premium on the debt amortizes faster than expected. Conversely, decreases in prepayment rates result in increased expense and can extend the period over which the Company amortizes the premium. For debt issued at a discount, as prepayment rates increase, the amount of interest the Company expenses increases from the acceleration of the accretion of the discount into interest expense. Conversely, decreases in prepayment rates result in decreased expense as the accretion of the discount into interest expense occurs over a longer period. A summary of the significant inputs used to estimate the fair value of Level 3 Non-Agency RMBS held for investment at fair value as of September 30, 2024 and December 31, 2023 follows. The weighted average discount rates are based on fair value.

Disclosure of Repurchase Agreements [Abstract]
Secured Financing Agreements	Secured Financing Agreements Secured financing agreements include short term repurchase agreements with original maturity dates of less than one-year, long-term financing agreements with original maturity dates of more than one year and loan warehouse credit facilities collateralized by loans acquired by the Company. At September 30, 2024 and December 31, 2023, the repurchase agreements are collateralized by Agency and Non-Agency mortgage-backed securities with interest rates generally indexed to the Secured Overnight Financing Rate (“SOFR”). The maturity dates on the repurchase agreements are all less than one year and generally are less than 180 days. The collateral pledged as security on the repurchase agreements may include the Company’s investments in bonds issued by consolidated VIEs, which are eliminated in consolidation. The long-term financing agreements include secured financing arrangements with an original term of one year or greater which is secured by Non-Agency RMBS pledged as collateral. These long-term secured financing agreements have a maturity date of October 2025. The collateral pledged as security on the long-term financing agreements may include the Company’s investments in bonds issued by consolidated VIEs, which are eliminated in consolidation. The warehouse credit facilities collateralized by loans are repurchase agreements intended to finance loans until they can be sold into a longer-term securitization structure. The maturity dates on the warehouse credit facilities range from three months to one year with interest rates indexed to SOFR. The secured financing agreements generally require the Company to post collateral at a specific rate in excess of the unpaid principal balance of the agreement. For certain secured financing agreements, this may require the Company to post additional margin if the fair value of the assets were to drop. To mitigate this risk, the Company has negotiated several long-term financing agreements which are not subject to additional margin requirements upon a drop in the fair value of the collateral pledged or until the drop is greater than a threshold. At September 30, 2024 and December 31, 2023, the Company has $869 million and $924 million, respectively, of secured financing agreements which are not subject to additional margin requirements upon a change in the fair value of the collateral pledged. At September 30, 2024 and December 31, 2023, the Company has $519 million and $546 million, respectively, of secured financing agreements which are not subject to additional margin requirements until the drop in the fair value of collateral is greater than a threshold. Repurchase agreements may allow the credit counterparty to avoid the automatic stay provisions of the Bankruptcy Code, in the event of a bankruptcy of the Company, and take possession of, and liquidate, the collateral under such repurchase agreements without delay. At September 30, 2024 and December 31, 2023, we pledged $13 million and $23 million respectively, of margin cash collateral to the Company's secured financing agreement counterparties. At September 30, 2024, the weighted average haircut on the Company's secured financing agreements collateralized by Agency RMBS was 5.4%, Agency CMBS was 5.6% and Non-Agency RMBS and Loans held for investment was 26.2%. At December 31, 2023, the weighted average haircut on the Company's secured financing agreements collateralized by Agency CMBS was 5.2% and Non-Agency RMBS and Loans held for investment was 26.1%. Certain of the long-term financing agreements and warehouse credit facilities are subject to certain covenants. These covenants include that the Company maintain its REIT status as well as maintain a net asset value or GAAP equity greater than a certain level. If the Company fails to comply with these covenants at any time, the financing may become immediately due in full. Additionally, certain financing agreements become immediately due if the total stockholders' equity of the Company drops by 50% from the most recent year end. Currently, the Company is in compliance with all covenants and does not expect to fail to comply with any of these covenants within the next twelve months. The Company has a total of $1.9 billion unused uncommitted warehouse credit facilities as of September 30, 2024. At September 30, 2024, the Company had amounts at risk with Nomura Securities International, Inc., or Nomura, of 18% of its equity related to the collateral posted on secured financing agreements. The weighted average maturities of the secured financing agreements with Nomura were 172 days. The amount at risk with Nomura was $495 million. At December 31, 2023, the Company had amounts at risk with Nomura of 17% of its equity related to the collateral posted on secured financing agreements. The weighted average maturities of the secured financing agreements with Nomura were 412 days. The amount at risk with Nomura was $433 million.

Debt Disclosure [Abstract]
Securitized Debt	Securitized Debt All of the Company’s securitized debt is collateralized by residential mortgage loans or Non-Agency RMBS. For financial reporting purposes, the Company’s securitized debt is accounted for as secured borrowings. Thus, the residential mortgage loans or RMBS held as collateral are recorded in the assets of the Company as Loans held for investment or Non-Agency RMBS and the securitized debt is recorded as a non-recourse liability in the accompanying Consolidated Statements of Financial Condition. Securitized Debt Collateralized by Non-Agency RMBS At September 30, 2024 and December 31, 2023, the Company’s securitized debt collateralized by Non-Agency RMBS was carried at amortized cost and had a principal balance of $110 million, respectively. At September 30, 2024 and December 31, 2023, the debt carried a weighted average coupon of 6.7%. As of September 30, 2024, the maturities of the debt range between the years 2036 and 2037. None of the Company’s securitized debt collateralized by Non-Agency RMBS is callable. The Company did not acquire any securitized debt collateralized by Non-Agency RMBS during the quarters and nine months ended September 30, 2024 and 2023. The following table presents the estimated principal repayment schedule of the securitized debt collateralized by Non-Agency RMBS at September 30, 2024 and December 31, 2023, based on expected cash flows of the residential mortgage loans or RMBS, as adjusted for projected losses on the underlying collateral of the debt. All of the securitized debt recorded in the Company’s Consolidated Statements of Financial Condition is non-recourse to the Company.

During the quarter and nine months ended September 30, 2024, the Company did not acquire any securitized debt collateralized by Loans held for investment. During the nine months ended September 30, 2023, the Company acquired securitized debt collateralized by Loans held for investment with an amortized cost balance of $551 million for $545 million. These transactions resulted in net gain on extinguishment of debt of $6 million. During the quarter ended September 30, 2023, the Company did not acquire any securitized debt collateralized by Loans held for investment. The following table presents the estimated principal repayment schedule of the securitized debt collateralized by Loans held for investment at September 30, 2024 and December 31, 2023, based on expected cash flows of the residential mortgage loans or RMBS, as adjusted for projected losses on the underlying collateral of the debt. All of the securitized debt recorded in the Company’s Consolidated Statements of Financial Condition is non-recourse to the Company.

The estimate of their repayment is based on scheduled principal payments on the underlying loans. This estimate will differ from actual amounts to the extent prepayments or loan losses are experienced. See Note 4 for a more detailed discussion of the loans collateralizing the securitized debt. Certain of the securitized debt collateralized by Loans held for investment contain call provisions at the option of the Company at a specific date. Other securitized debt issued by the Company contain clean-up call provisions. A clean-up call provision is a right to call the outstanding debt at pre-defined terms when the collateral falls below a certain percentage of the original balance, typically 10%. Generally, these clean-up call rights are shared with other parties to the debt, including the loan servicers and the paying agents. Clean-up calls are generally put in place to reduce the administrative burdens when a loan pool balance becomes de minimis hence uneconomical to manage. The following table presents the par value of the callable debt by year as of September 30, 2024, excluding any debt issued by the Company where the Company only has a clean-up call.

Consolidated Securitization Vehicles and Other Variable Interest Entities	Consolidated Securitization Vehicles and Other Variable Interest Entities Since its inception, the Company has utilized VIEs for the purpose of securitizing whole mortgage loans or re-securitizing RMBS and obtaining long-term, non-recourse financing. The Company evaluated its interest in each VIE to determine if it is the primary beneficiary. During the quarter and nine months ended September 30, 2024, the Company consolidated approximately $468 million unpaid principal balance of seasoned reperforming residential mortgage loans. During the quarter and nine months ended September 30, 2023, the Company consolidated approximately $1.4 billion and $2.6 billion, respectively, unpaid principal balance of seasoned residential reperforming residential mortgage loans. VIEs for Which the Company is the Primary Beneficiary The retained beneficial interests in VIEs for which the Company is the primary beneficiary are typically the subordinated tranches of these securitizations and in some cases the Company may hold interests in additional tranches. The table below reflects the assets and liabilities recorded in the Consolidated Statements of Financial Condition related to the consolidated VIEs as of September 30, 2024 and December 31, 2023.

In such cases, the Company does not have both the power to direct the entities’ most significant activities, such as rights to replace the servicer without cause, and the obligation to absorb losses or right to receive benefits that could potentially be significant to the VIEs. The Company’s investments in these unconsolidated VIEs are carried in Non-Agency RMBS on the Consolidated Statements of Financial Condition and include senior and subordinated bonds issued by the VIEs.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments In connection with the Company’s interest rate risk strategy, the Company may economically hedge a portion of its interest rate risk by entering into derivative financial instrument contracts in the form of interest rate swaps, swaptions, and U.S. Treasury futures. Swaps are used to lock in a fixed rate related to a portion of its current and anticipated payments on its secured financing agreements. The Company typically agrees to pay a fixed rate of interest, or pay rate, in exchange for the right to receive a floating rate of interest, or receive rate, over a specified period of time. Interest rate swaptions provide the option to enter into an interest rate swap agreement for a predetermined notional amount, stated term and pay and receive interest rates in the future. The Company’s swaptions are not centrally cleared. U.S. Treasury futures are derivatives which track the prices of generic benchmark U.S. Treasury securities with identical maturity and are traded on an active exchange. It is generally the Company’s policy to close out any U.S. Treasury futures positions prior to delivering the underlying security. U.S. Treasury futures lock in a fixed rate related to a portion of its current and anticipated payments on its secured financing agreements. The Company’s derivatives are recorded as either assets or liabilities in the Consolidated Statements of Financial Condition and measured at fair value. These derivative financial instrument contracts are not designated as hedges for GAAP; therefore, all changes in fair value are recognized in earnings. The Company elects to net the fair value of its derivative contracts by counterparty when appropriate. These contracts contain legally enforceable provisions that allow for netting or setting off of all individual derivative receivables and payables with each counterparty and therefore, the fair values of those derivative contracts are reported net by counterparty. The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized if the counterparties to these instruments fail to perform their obligations under the contracts. In the event of a default by the counterparty, the Company could have difficulty obtaining its RMBS or cash pledged as collateral for these derivative instruments. The Company periodically monitors the credit profiles of its counterparties to determine if it is exposed to counterparty credit risk. See Note 15 for further discussion of counterparty credit risk. The weighted average pay rate on the Company’s interest rate swaps at September 30, 2024 was 3.56% and the weighted average receive rate wa s 4.96%. At September 30, 2024, the weighted average maturity on the Company’s interest rate swaps was less than one year. The weighted average pay rate on the Company’s interest rate swap at December 31, 2023 was 3.26% and the weighted average receive rate was 5.40%. At December 31, 2023, the weighted average maturity on the Company’s interest rate swaps was less than one year. The Company had no swap terminations during the quarter ended September 30, 2024 and 2023, respectively. The Company had a realized loss of $17 million related to the maturity of one swap during the nine months ended September 30, 2024. The Company paid $45 million to terminate interest rate swaps with a notional value of $2.5 billion during the nine m onths ended September 30, 2023. The terminated swaps had original maturities ranging from 2025 to 2028. During the nine months ended September 30, 2024, the Company exercised three swaption contracts, each with $500 million notional, and entered into three one-year swaps, each with $500 million notional and a weighted average fixed pay rate of 3.56%. During the nine months ended September 30, 2023, the Company entered into three swaption contracts for a one-year forward starting swaps with a total notional of $1.5 billion with a 3.56% strike rate. The underlying swap terms will allow the Company to pay a fixed rate of 3.56% and receive floating overnight SOFR rate. Additionally, during the nine months ended 2023, the Company terminated its existing $1.0 billion notional swaption contract for a one-year forward starting swap. The Company also entered and terminated three new swaptions contracts with $2.3 billion notional during the nine months ended September 30, 2023. The Company had net realized gains of $11 million on these swaption terminations. During the quarter and nine months ended September 30, 2024, the Company entered into 1,391 short 5-year and 1,684 short 5-year U.S. Treasury futures contract with a notional of $139 million and $168 million, respectively, which it subsequently covered for a net realized loss of $4.9 million. The Company had no outstanding U.S. Treasury futures contract at September 30, 2024. During the nine months ended September 30, 2023, the Company entered into 6,000 short 5-year and 1,875 short 2-year U.S. Treasury futures contract with a notional of $600 million and $375 million, respectively, which it subsequently covered and had no outstanding U.S. Treasury futures contract at September 30, 2023. The Company had a net realized loss of $6 million on covering these short U.S. Treasury futures contract. The Company also entered into 400 call options on 2-year and 5-year U.S. Treasury futures and subsequently covered them during the nine months ended September 30, 2023 for a realized loss of $187 thousand. The Company also maintains collateral in the form of cash margin from its counterparties to its derivative contracts. In accordance with the Company's netting policy, the Company presents the fair value of its derivative contracts net of cash margin received. See Note 15 for additional details on derivative netting.

Upon the occurrence of any one of items (i) through (iv), or another default under the agreement, the counterparty to the applicable agreement has a right to terminate the agreement in accordance with its provisions. If the Company breaches any of these provisions, it will be required to settle its obligations under the agreements at their termination values, which approximates fair value.

In January 2024, the Company's Board of Directors updated the authorization to include the Company's preferred stock into the Repurchase Program and increased the authorization by $33 million back up to $250 million. Such authorization does not have an expiration date, and at present, there is no intention to modify or otherwise rescind such authorization. Shares of the Company's common stock and preferred stock may be purchased in the open market, including through block purchases, through privately negotiated transactions, or pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, or the Exchange Act. The timing, manner, price and amount of any repurchases will be determined at the Company's discretion and the program may be suspended, terminated or modified at any time, for any reason. Among other factors, the Company intends to only consider repurchasing shares of its common stock when the purchase price is less than the last publicly reported book value per common share. In addition, the Company does not intend to repurchase any shares from directors, officers or other affiliates. The program does not obligate the Company to acquire any specific number of shares, and all repurchases will be made in accordance with Rule 10b-18, which sets certain restrictions on the method, timing, price and volume of stock repurchases. The Company did not repurchase any of its common stock during the quarter and nine months ended September 30, 2024.

The Company repurchased 5.8 million shares of its common stock at an average price of $5.66 for a total of $33 million during the nine months ended September 30, 2023 . The approximate dollar value of shares that may yet be purchased under the Repurchase Program is $250 million as of September 30, 2024. In 2022, the Company entered into separate Distribution Agency Agreements (the “Existing Sales Agreements”) with each of Credit Suisse Securities (USA) LLC, JMP Securities LLC, Goldman Sachs & Co.

As a result of the reverse stock split, every three shares of the Company’s common stock was converted into one share of common stock, reducing the number of issued and outstanding shares of the Company’s common stock from approximately 241 million to approximately 80 million and reducing the number of authorized shares from 500 million to approximately 167 million. No fractional shares were issued in connection with the reverse stock split. Each stockholder who was otherwise entitled to receive a fractional share of the Company’s common stock was entitled to receive a cash payment in lieu of a fractional share. The reverse stock split was not subject to stockholder approval and did not change the par value of the Company's common stock. All common shares, outstanding options and per share amounts for all periods presented were retroactively adjusted to reflect the reverse stock split. During the quarter and nine months ended September 30, 2024, the Company declared dividends to common shareholders of $30 million and $87 million or $0.37 and $1.05 per share, respectively.

Any awards outstanding under the Prior Plan will remain subject to and be paid under the Prior Plan. Any shares subject to outstanding awards under the Prior Plan that expire, terminate, or are surrendered or forfeited for any reason without issuance of shares will automatically become available for issuance under the Plan. Also, shares withheld for tax withholding requirements after stockholder approval of the Plan for full value awards originally granted under the Prior Plan (such as the RSUs and PSUs awarded to our named executive officers) will automatically become available for issuance under the Plan. As of September 30, 2024, approximately 6 million shares were available for future grant under the Plan. Awards under the Plan may include stock options, stock appreciation rights (“SARs”), restricted stock, dividend equivalent rights (“DERs”) and other share-based awards (including RSUs). Under the Plan, any of these awards may be performance awards that are conditioned on the attainment of performance goals. The Compensation Committee of the Board of Directors of the Company has approved a Stock Award Deferral Program, or the Deferral Program. Under the Deferral Program, non-employee directors and certain executive officers can elect to defer payment of certain stock awards made pursuant to the Incentive Plan. Deferred awards are treated as deferred stock units and paid at the earlier of separation from service or a date elected by the participant who is separating. Payments are generally made in a lump sum or, if elected by the participant, in five annual installments. Deferred awards receive dividend equivalents during the deferral period in the form of additional deferred stock units. Amounts are paid at the end of the deferral period by delivery of shares from the Incentive Plan (plus cash for any fractional deferred stock units), less any applicable tax withholdings. Deferral elections do not alter any vesting requirements applicable to the underlying stock award. At September 30, 2024 and December 31, 2023, there are approximately 105 thousand and 343 thousand shares for which payments have been deferred until separation or a date elected by the participant, respectively. At September 30, 2024 and December 31, 2023, there are approximately 209 thousand and 378 thousand dividend equivalent rights earned but not yet delivered, respectively. Grants of Restricted Stock Units, or RSUs The Company did not grant any RSUs during the quarters ended September 30, 2024 and 2023. During the nine months ended September 30, 2024 and 2023, the Company granted RSU awards to senior management. These RSU awards are designed to reward employees of the Company for services provided to the Company. Generally, the RSU aw ards vest equally over a three-year period and will fully vest after three years. For employees who are retirement eligible, defined as years of service to the Company plus age that is equal to or greater than 65, the service period is considered to be fulfilled and all grants are expensed immediately. The RSU awards are valued at the market price of the Company’s common stock on the grant date and generally the employees must be employed by the Company on the vesting dates to receive the RSU awards. The Company granted 240 thousand RSU awards during the quarter and nine months ended September 30, 2024 with a grant date fair value of $4 million for the 2023 performance year . The Company granted 273 thousand RSU awards during the nine months ended September 30, 2023 with a grant date fair value of $5 million for the 2023 performance year. Grants of Performance Share Units, or PSUs PSU awards are designed to align compensation with the Company’s future performance. The PSU awards granted during the nine months ended September 30, 2024 and 2023, include a three-year performance period ending on December 31, 2026 and December 31, 2025, respectively. For the PSU awards granted during the nine months ended September 30, 2024, and 2023, the final number of shares awarded will be between 0% and 200% of the PSUs granted based equally on the Company Economic Return and share price performance compared to a peer group. The Company’s three-year Company Economic Return is equal to the Company’s change in book value per common share plus common stock dividends. Share price performance equals change in share price plus common stock dividends. Compensation expense will be recognized on a straight-line basis over the three-year vesting period based on an estimate of the Company Economic Return and share price performance in relation to the entities in the peer group and will be adjusted each period based on the Company’s best estimate of the actual number of shares awarded. The Company did not grant any PSU awards during the quarters ended September 30, 2024 and 2023. For the nine months ended September 30, 2024, the Company granted 179 thousand PSU awards to senior management with a grant date fair value of $3 million. For the nine months ended September 30, 2023, the Company granted 202 thousand PSU awards to senior management with a grant date fair value of $3 million. The Company recognized stock-based compensation expense of $2 million and $7 million for the quarter and nine months ended September 30, 2024. The Company recognized stock-based compensation expense of $2 million and $6 million for the quarter and nine months ended September 30, 2023.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the year ended December 31, 2023, the Company qualified to be taxed as a REIT under Code Sections 856 through 860. As a REIT, the Company is not subject to U.S. federal income tax to the extent that it makes qualifying distributions of taxable income to its stockholders. To maintain qualification as a REIT, the Company must distribute at least 90% of its annual REIT taxable income (subject to certain adjustments) to its shareholders and meet certain other requirements such as assets it may hold, income it may generate and its shareholder composition. It is generally the Company’s policy to distribute to its shareholders all of the Company’s taxable income. The state and local tax jurisdictions in 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 and its TRSs are subject to U.S. federal, state, and local taxes. The Company recorded current income tax expense of $16 thousand and $55 thousand for the quarter and nine months ended September 30, 2024, respectively. The Company recorded current income tax expense of $75 thousand and $100 thousand for the quarter and nine months ended September 30, 2023, respectively. The Company’s effective tax rate differs from its combined U.S. federal, state, and local corporate statutory tax rate primarily due to the deduction of dividend distributions required to be paid under Code Section 857(a). The Company’s U.S. federal, state and local tax returns for the tax years ending on or after December 31, 2021, remain open for examination.

Offsetting [Abstract]
Credit Risk and Interest Rate Risk	Credit Risk and Interest Rate Risk The Company’s primary components of market risk are credit risk and interest rate risk. The Company is subject to interest rate risk in connection with its investments in Agency MBS and Non-Agency RMBS, residential mortgage loans, borrowings under secured financing agreements and securitized debt. When the Company assumes interest rate risk, it attempts to minimize interest rate risk through asset selection, hedging and matching the income earned on mortgage assets with the cost of related financing. The Company attempts to minimize credit risk through due diligence, asset selection and portfolio monitoring. The Company has established a whole loan target market including qualified mortgages, non-qualified mortgages and reperforming residential mortgage loans. Additionally, the Company seeks to minimize credit risk through compliance with regulatory requirements, geographic diversification, owner occupied property, and moderate loan-to-value ratios. These factors are considered to be important indicators of credit risk. By using derivative instruments and secured financing agreements, the Company is exposed to counterparty credit risk if counterparties to the contracts do not perform as expected. If a counterparty fails to perform on a derivative instrument, the Company’s counterparty credit risk is equal to the amount reported as a derivative asset on its balance sheet to the extent that amount exceeds collateral obtained from the counterparty or, if in a net liability position, the extent to which collateral posted exceeds the liability to the counterparty. The amounts reported as a derivative asset/(liability) are derivative contracts in a gain/(loss) position, and to the extent subject to master netting arrangements, net of derivatives in a loss/(gain) position with the same counterparty and collateral received/(pledged). If the counterparty fails to perform on a secured financing agreement, the Company is exposed to a loss to the extent that the fair value of collateral pledged exceeds the liability to the counterparty. The Company attempts to minimize counterparty credit risk by evaluating and monitoring the counterparty’s credit, executing master netting arrangements and obtaining collateral, and executing contracts and agreements with multiple counterparties to reduce exposure to a single counterparty. The Company's secured financing agreements transactions are governed by underlying agreements that provide for a right of setoff by the lender, including in the event of default or in the event of bankruptcy of the borrowing party to the transactions. The Company's derivative transactions are governed by underlying agreements that provide for a right of setoff under master netting arrangements, including in the event of default or in the event of bankruptcy of either party to the transactions. The Company presents its assets and liabilities subject to such arrangements on a net basis in the Consolidated Statements of Financial Condition. The following table presents information about our assets and liabilities that are subject to such arrangements and can potentially be offset on our consolidated statements of financial condition as of September 30, 2024 and December 31, 2023.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation and Statements of Financial Condition Presentation	Basis of Presentation and Consolidation The accompanying consolidated financial statements and related notes of the Company have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP. In the opinion of the Company, all normal and recurring adjustments considered necessary for a fair presentation of its financial position, results of operations and cash flows have been included. Investment transactions are recorded on the trade date. Certain prior year amounts have been reclassified to conform to the current year’s presentation. All per share amounts, common shares outstanding and restricted shares for all periods presented reflect the Company's 1-for-3 reverse stock split, which was effective after the close of trading on May 21, 2024. The consolidated financial statements include the Company’s accounts, the accounts of its wholly-owned subsidiaries, and variable interest entities, or VIEs, in which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. The Company uses securitization trusts considered to be VIEs in its securitization transactions. VIEs are defined as entities in which equity investors (i) do not have the characteristics of a controlling financial interest, or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The entity that consolidates a VIE is known as its primary beneficiary and is generally the entity with (i) the power to direct the activities that most significantly impact the VIEs’ economic performance, and (ii) the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could 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 VIEs’ economic performance may be determined by an entity’s involvement with the design and structure of the VIE. The trusts are structured as entities 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 risks associated with being the sponsor and depositor of and the seller, directly or indirectly to, the securitizations 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 of the VIEs that most significantly impact the VIEs’ economic performance, or power, such as rights to replace the servicer without cause, or the Company was determined to have power in connection with its involvement with the structure and design of the VIE. The Company’s interest in the assets held by these securitization vehicles, which are consolidated on the Company’s Consolidated Statements of Financial Condition, is restricted by the structural provisions of these trusts, and a recovery of the Company’s investment in the vehicles will be limited by each entity’s distribution provisions. Generally, the securities retained by the Company are the most subordinate in the capital structure, which means those securities receive distributions after the senior securities have been paid. The liabilities of the securitization vehicles, which are also consolidated on the Company’s Consolidated Statements of Financial Condition, are non-recourse to the Company, and can only be satisfied using proceeds from each securitization vehicle’s respective asset pool.
Net Income per Share	Net Income per ShareThe Company calculates basic net income per share by dividing net income for the period by the basic weighted-average shares of its common stock outstanding for that period. Diluted net income per share takes into account the effect of dilutive instruments such as unvested restricted stock units.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although the Company’s estimates contemplate current conditions and how it expects them to change in the future, it is reasonably possible that actual conditions could be materially different than anticipated in those estimates, which could have a material adverse impact on the Company’s results of operations and its financial condition. The Company has made significant estimates including in accounting for income recognition on Agency MBS, Non-Agency RMBS, IO MBS (Note 3) and residential mortgage loans (Note 4), valuation of Agency MBS and Non-Agency RMBS (Notes 3 and 5), residential mortgage loans (Notes 4 and 5), secured financing agreements (Notes 5 and 6), and securitized debt (Notes 5 and 7). Actual results could differ materially from those estimates.
Long Term Debt	Long Term Debt The Company's Long Term Debt is comprised of unsecured senior notes. Unsecured senior notes are carried at their unpaid principal balance net of any unamortized deferred issuance costs. Interest on the notes is payable quarterly until such time the notes mature. Any debt discounts or premiums are reported as an adjustment to the carrying amount of the debt liability and amortized into interest expense using the effective interest method. Deferred debt issuance costs are expenses associated with the issuance of long-term debt. These expenses typically include underwriting, legal, accounting, and other fees. Deferred debt issuance costs are included in the carrying value of the related long-term debt issued and are amortized as an adjustment to interest expense using the effective interest method, based upon the actual and estimated repayment schedules of the related long-term debt issued.
Fair Value Disclosure	Fair Value Disclosure A complete discussion of the methodology utilized by the Company to estimate the fair value of its financial instruments is included in Note 5 to these consolidated financial statements.
Income Taxes	Income Taxes
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280); Improvements to Reportable Segment Disclosures. This standard requires public companies to disclose information about their reportable segments' significant expenses on an interim and annual basis to provide more transparency about the expenses they incur from revenue generating business units. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not expect the adoption of the new standard to have a material effect on its Consolidated Financial Statements.
