Summary of Significant Accounting Policies (Policies)	9 Months Ended
Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	On March 9, 2023, the Company effected a one-for-four reverse stock split of its issued, outstanding and authorized shares of common stock (the "Reverse Stock Split"). Accordingly, all common share and per common share data for all periods presented in these condensed consolidated financial statements and notes thereto have been adjusted on a retroactive basis to reflect the impact of the Reverse Stock Split. The accompanying condensed consolidated balance sheet as of December 31, 2023 has been derived from audited financial statements. The accompanying condensed consolidated balance sheet as of September 30, 2024, the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2024 and 2023, the accompanying condensed consolidated statements of comprehensive income (loss) for the three and nine months ended September 30, 2024 and 2023, the accompanying condensed consolidated statements of changes in stockholders’ equity for the three and nine months ended September 30, 2024 and 2023 and the accompanying condensed consolidated statements of cash flows for the nine months ended September 30, 2024 and 2023 are unaudited. In our opinion, all adjustments (which include only normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations and cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with Article 10 of Regulation S-X and the instructions to Form 10-Q. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the U.S. Securities and Exchange Commission (“SEC”). Accordingly, significant accounting policies and other disclosures have been omitted since such items are disclosed in Note 2 in the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023. Provided in this section is a summary of additional accounting policies that are significant to, or newly adopted by, the Company for the three and nine months ended September 30, 2024. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the operating results for the full year. The accompanying condensed consolidated financial statements have been prepared on the accrual basis of accounting in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires management 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. Management has made significant estimates in several areas, including fair valuation of its financial instruments reported at fair value, real estate held by Consolidated VIEs and redemption value of redeemable non-controlling interests in Consolidated VIEs. Although the Company’s estimates contemplate current conditions and how it expects those conditions to change in the future, it is reasonably possible that actual conditions could be different than anticipated in those estimates, which could materially impact the Company’s results of operations and its financial condition.
Reclassifications	Certain prior period amounts have been reclassified in the accompanying condensed consolidated financial statements to conform to current period presentation. In particular, prior period disclosures have been adjusted for the aforementioned Reverse Stock Split. Additionally, prior period disclosures have been conformed to the current period presentation of net loss from real estate. Beginning in the third quarter of 2023, the components of net loss from real estate, inclusive of rental income and other real estate income and interest expense, mortgages payable on real estate, depreciation and amortization and other real estate expenses, are presented as total net loss from real estate on the Company's condensed consolidated statements of operations. Previously, rental income, other real estate income and total income from real estate was presented in other income (loss) and interest expense, mortgages payable on real estate, depreciation and amortization, other real estate expenses and total expenses related to real estate were presented in general, administrative and operating expenses on the Company's condensed consolidated statements of operations. Also beginning in the third quarter of 2023, unrealized gains (losses) and realized gains (losses) on derivative instruments are presented in gains (losses) on derivative instruments, net on the Company's condensed consolidated statements of operations. Previously, unrealized gains (losses) on derivative instruments were presented in unrealized gains (losses), net and realized gains (losses) on derivative instruments were presented in realized gains (losses), net on the Company's condensed consolidated statements of operations.
Principles of Consolidation and Variable Interest Entities	The accompanying condensed consolidated financial statements of the Company include the accounts of all its subsidiaries which are majority-owned, controlled by the Company or a VIE where the Company is the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in consolidation (see Note 7). A VIE is an entity that lacks one or more of the characteristics of a voting interest entity. A VIE is defined as an entity in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The Company consolidates a VIE in accordance with ASC 810, Consolidation ("ASC 810") when it is the primary beneficiary of such VIE, herein referred to as a Consolidated VIE. As primary beneficiary, the Company has both the power to direct the activities that most significantly impact the economic performance of the VIE and a right to receive benefits or absorb losses of the entity that could be potentially significant to the VIE. The Company is required to reconsider its evaluation of whether to consolidate a VIE each reporting period, based upon changes in the facts and circumstances pertaining to the VIE. The Company evaluates the initial consolidation of each Consolidated VIE, which includes a determination of whether the VIE constitutes the definition of a business in accordance with ASC 805, Business Combinations ("ASC 805"), by considering if substantially all of the fair value of the gross assets within the VIE are concentrated in either a single identifiable asset or group of single identifiable assets. Upon consolidation, the Company recognizes the assets acquired, the liabilities assumed, and any third-party ownership of membership interests as non-controlling interest as of the consolidation or acquisition date, measured at their relative fair values (see Note 7). Non-controlling interest in Consolidated VIEs is adjusted prospectively for its share of the allocation of income or loss and equity contributions and distributions from each respective Consolidated VIE. The third-party owners of certain of the non-controlling interests in Consolidated VIEs have the ability to sell their ownership interests to the Company, at their election, subject to certain conditions. The Company has classified these third-party ownership interests as redeemable non-controlling interest in Consolidated VIEs in mezzanine equity on the accompanying condensed consolidated balance sheets.
Collateralized Debt Obligations	The Company records collateralized debt obligations used to permanently finance the residential loans held in Consolidated SLST, a portion of the Company's net investment in Consolidated SLST and the Company's residential loans held in securitization trusts as debt on the accompanying condensed consolidated balance sheets. For financial reporting purposes, the loans and investment securities held as collateral for these obligations are recorded as assets of the Company. The Company has elected the fair value option pursuant to ASC 825, Financial Instruments ("ASC 825") with respect to the CDOs issued by Consolidated SLST and CDOs issued by the Company after January 1, 2024. The Company elected the fair value option for CDOs issued by the Company after January 1, 2024 because the Company determined that such presentation represents the underlying economics of the respective financing. Changes in fair value of CDOs subject to the fair value election are recorded in current period earnings in unrealized gains (losses), net on the accompanying condensed consolidated statements of operations. Interest expense on such CDOs is recorded based on the current stated interest rate and outstanding principal balance in effect and is included in interest expense on the accompanying condensed consolidated statements of operations. In accordance with ASC 825, costs associated with the issuance of CDOs subject to the fair value election are recognized in earnings as they are incurred and are included in debt issuance costs on the accompanying condensed consolidated statements of operations. Senior Unsecured Notes – On April 27, 2021, the Company issued its 5.75% Senior Notes due 2026 to originate new investments, repay outstanding indebtedness and for general corporate purposes. The Company evaluated the call option feature of these notes for embedded derivatives in accordance with ASC 815, Derivatives and Hedging ("ASC 815") and determined that the call option feature should not be bifurcated from the notes. On June 28, 2024, the Company issued its 9.125% Senior Notes due 2029 (the "9.125% Senior Notes") for general corporate purposes, which included acquiring single-family residential assets. The Company evaluated the call option feature of these notes for embedded derivatives in accordance with ASC 815 and determined that the call option feature should not be bifurcated from the notes. The Company has elected the fair value option pursuant to ASC 825 with respect to the 9.125% Senior Notes because the Company determined that such presentation represents the underlying economics of the respective financing. Changes in fair value of the 9.125% Senior Notes are recorded in current period earnings in unrealized gains (losses), net on the accompanying condensed consolidated statements of operations (or other comprehensive income, to the extent the change results from a change in instrument-specific credit risk). Interest expense on such 9.125% Senior Notes is recorded based on the current stated interest rate and outstanding principal balance in effect and is included in interest expense on the accompanying condensed consolidated statements of operations. In accordance with ASC 825, costs associated with the issuance of the 9.125% Senior Notes are recognized in earnings as they are incurred and are included in debt issuance costs on the accompanying condensed consolidated statements of operations.
Summary of Recent Accounting Pronouncements	In December 2023, the FASB issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 requires enhanced disclosures in connection with an entity's effective tax rate reconciliation and additional disclosures about income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The Company expects that the adoption of ASU 2023-09 will result in additional income tax disclosures in its notes to consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis. The amendments also require companies with a single reportable segment to provide all disclosures required by ASU 2023-07 as well as existing segment disclosures in accordance with ASC 280. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company expects that the adoption of ASU 2023-07 will result in additional disclosures in its notes to consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). ASU 2020-04 provides optional expedients and exceptions to GAAP requirements for modifications to debt agreements, leases, derivatives and other contracts, related to the expected market transition from LIBOR, and certain other floating rate benchmark indices, or collectively, IBORs, to alternative reference rates. ASU 2020-04 generally considers contract modifications related to reference rate reform to be an event that does not require contract remeasurement at the modification date nor a reassessment of a previous accounting determination. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 ("ASU 2022-06"), which allows ASU 2020-04 to be adopted and applied prospectively to contract modifications made on or before December 31, 2024. In light of the cessation of the publication of LIBOR after June 30, 2023, the Company’s material contracts that were indexed to LIBOR have been amended to transition to an alternative benchmark and any other unmodified agreements that incorporate LIBOR as the referenced rate have provisions in place that provide for identification of an alternative benchmark or specify an alternative benchmark, or by operation of law specify an alternative benchmark, to LIBOR upon its phase-out.
Fair Value of Financial Instruments	The Company has established and documented processes for determining fair values. Fair value is based upon quoted market prices, where available. If listed prices or quotes are not available, then fair value is based upon internally developed models that primarily use inputs that are market-based or independently-sourced market parameters, including interest rate yield curves. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of valuation hierarchy are defined as follows: Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or 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 the fair value measurement. The following describes the valuation methodologies used for the Company’s financial instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy. a.Residential Loans Held in Consolidated SLST – Residential loans held in Consolidated SLST are carried at fair value and classified as Level 3 fair values. In accordance with the practical expedient in ASC 810, the Company determines the fair value of residential loans held in Consolidated SLST based on the fair value of the CDOs issued by the respective securitizations and its investment in the securitizations (eliminated in consolidation in accordance with GAAP), as the fair value of these instruments is more observable. The investment securities (eliminated in consolidation in accordance with GAAP) that we own in the securitizations are generally illiquid and trade infrequently. As such, they are classified as Level 3 in the fair value hierarchy. The fair valuation of these investment securities is determined based on an internal valuation model that considers expected cash flows from the underlying loans and yields required by market participants. The significant unobservable inputs used in the measurement of these investments are projected losses within the pool of loans and a discount rate. The discount rate used in determining fair value incorporates default rate, loss severity, prepayment rate and current market interest rates. Significant increases or decreases in these inputs would result in a significantly lower or higher fair value measurement. b.Residential Loans and Residential Loans Held in Securitization Trusts – The Company’s acquired residential loans are recorded at fair value and classified as Level 3 in the fair value hierarchy. The fair value for residential loans is determined using valuations obtained from a third party that specializes in providing valuations of residential loans. The valuation approach depends on whether the residential loan is considered performing, re-performing or non-performing at the date the valuation is performed. For performing and re-performing loans, estimates of fair value are derived using a discounted cash flow model, where estimates of cash flows are determined from scheduled payments for each loan, adjusted using forecast prepayment rates, default rates and rates for loss upon default. For non-performing loans, asset liquidation cash flows are derived based on the estimated time to liquidate the loan, expected liquidation costs and home price appreciation. Estimated cash flows for both performing and non-performing loans are discounted at yields considered appropriate to arrive at a reasonable exit price for the asset. Indications of loan value such as actual trades, bids, offers and generic market color may be used in determining the appropriate discount yield. The Company independently calculates the fair value of residential loans based on discounted cash flows using an internal pricing model to validate all third party valuations of residential loans. The Company has established thresholds to compare internally generated prices with independent third-party prices and any differences that exceed the thresholds are reviewed both internally and with the third-party pricing service. The Company reconciles and resolves all pricing differences in excess of the thresholds before a final price is established. c.Preferred Equity and Mezzanine Loan Investments – Fair value for preferred equity and mezzanine loan investments is determined by both market comparable pricing and discounted cash flows. The discounted cash flows are based on the underlying estimated cash flows and estimated changes in market yields. The fair value also reflects consideration of changes in credit risk since origination or time of initial investment. This fair value measurement is generally based on unobservable inputs and, as such, is classified as Level 3 in the fair value hierarchy. d.Investment Securities Available for Sale – The Company determines the fair value of its Agency RMBS and non-Agency RMBS based on discounted cash flows utilizing an internal pricing model. The methodology considers the characteristics of the particular security and its underlying collateral, which are observable inputs. These inputs include, but are not limited to, delinquency status, coupon, loan-to-value ("LTV"), historical performance, periodic and life caps, collateral type, rate reset period, seasoning, prepayment speeds and credit enhancement levels. The Company also considers several observable market data points, including prices obtained from third-party pricing services or dealers who make markets in similar financial instruments, trading activity, and dialogue with market participants. Third-party pricing services typically incorporate commonly used market pricing methods, trading activity observed in the marketplace and other data inputs similar to those used in the Company's internal pricing model. The Company has established thresholds to compare internally generated prices with independent third-party prices and any differences that exceed the thresholds are reviewed both internally and with the third-party pricing service. The Company reconciles and resolves all pricing differences in excess of the thresholds before a final price is established. The Company determines the fair value of its U.S. Treasury securities using a third-party pricing service that compiles prices from various sources or using pricing models that consider observable market data to determine the fair value of identical or similar securities. The Company’s investment securities available for sale are valued based upon readily observable market parameters and are classified as Level 2 fair values. e.Equity Investments – Fair value for equity investments is determined (i) by the valuation process for preferred equity and mezzanine loan investments as described in c. above or (ii) using weighted multiples of origination volume and earnings before taxes, depreciation and amortization of the entity and the net asset value ("NAV") of the equity investment entity. These fair value measurements are generally based on unobservable inputs and, as such, are classified as Level 3 in the fair value hierarchy. f.Derivative Instruments – The fair values of the Company's interest rate cap agreements are measured using models developed by either third-party pricing providers or the respective counterparty that use the market-standard methodology of discounting the future expected cash receipts which would occur if floating interest rates rise above the strike rate of the caps. The floating interest rates used in the calculation of projected receipts on the interest rate caps are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. The inputs used in the valuation of interest rate caps fall within Level 2 of the fair value hierarchy. The Company's interest rate swaps and credit default swaps are classified as Level 2 fair values and are measured using valuations reported by the respective central clearing houses. The derivatives are presented net of variation margin payments pledged or received. The Company obtains additional third-party valuations for interest rate swaps, credit default swaps and interest rate cap agreements. The Company has established thresholds to compare different independent third-party prices and any differences that exceed the thresholds are reviewed both internally and with the third-party pricing services. The Company reconciles and resolves all pricing differences in excess of the thresholds before a final price is established. g.Collateralized Debt Obligations – CDOs issued by Consolidated SLST are classified as Level 3 fair values for which fair value is determined by considering several market data points, including prices obtained from third-party pricing services or dealers who make markets in similar financial instruments. The third-party pricing service or dealers incorporate common market pricing methods, including a spread measurement to the Treasury curve or interest rate swap curve as well as underlying characteristics of the particular security. They will also consider contractual cash payments and yields expected by market participants. Refer to a. above for a description of the fair valuation of CDOs issued by Consolidated SLST that are eliminated in consolidation. Fair value for CDOs issued by the Company's residential loan securitizations and non-Agency RMBS re-securitization is determined by the valuation process for investment securities available for sale as described in d. above and, as such, are classified as Level 2 fair values. h.Senior unsecured notes – The Company's 9.125% Senior Notes are valued using pricing models that consider observable market data to determine the fair value of identical or similar securities and are classified as Level 2 fair values. Management reviews all prices used in determining fair value to ensure they represent current market conditions. This review includes surveying similar market transactions and comparisons to interest pricing models as well as offerings of like securities by dealers. Any changes to the valuation methodology are reviewed by management to ensure the changes are appropriate. As markets and products develop and the pricing for certain products becomes more transparent, the Company continues to refine its valuation methodologies. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of 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 each reporting date, which may include periods of market dislocation, during which time price transparency may be reduced. This condition could cause the Company’s financial instruments to be reclassified from Level 2 to Level 3 in future periods.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2024

On March 9, 2023, the Company effected a one-for-four reverse stock split of its issued, outstanding and authorized shares of common stock (the "Reverse Stock Split"). Accordingly, all common share and per common share data for all periods presented in these condensed consolidated financial statements and notes thereto have been adjusted on a retroactive basis to reflect the impact of the Reverse Stock Split.

The accompanying condensed consolidated balance sheet as of December 31, 2023 has been derived from audited financial statements. The accompanying condensed consolidated balance sheet as of September 30, 2024, the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2024 and 2023, the accompanying condensed consolidated statements of comprehensive income (loss) for the three and nine months ended September 30, 2024 and 2023, the accompanying condensed consolidated statements of changes in stockholders’ equity for the three and nine months ended September 30, 2024 and 2023 and the accompanying condensed consolidated statements of cash flows for the nine months ended September 30, 2024 and 2023 are unaudited. In our opinion, all adjustments (which include only normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations and cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with Article 10 of Regulation S-X and the instructions to Form 10-Q. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the U.S. Securities and Exchange Commission (“SEC”). Accordingly, significant accounting policies and other disclosures have been omitted since such items are disclosed in Note 2 in the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023. Provided in this section is a summary of additional accounting policies that are significant to, or newly adopted by, the Company for the three and nine months ended September 30, 2024. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the operating results for the full year.

The accompanying condensed consolidated financial statements have been prepared on the accrual basis of accounting in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires management 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. Management has made significant estimates in several areas, including fair valuation of its financial instruments reported at fair value, real estate held by Consolidated VIEs and redemption value of redeemable non-controlling interests in Consolidated VIEs. Although the Company’s estimates contemplate current conditions and how it expects those conditions to change in the future, it is reasonably possible that actual conditions could be different than anticipated in those estimates, which could materially impact the Company’s results of operations and its financial condition.

Reclassifications

Certain prior period amounts have been reclassified in the accompanying condensed consolidated financial statements to conform to current period presentation. In particular, prior period disclosures have been adjusted for the aforementioned Reverse Stock Split.

Additionally, prior period disclosures have been conformed to the current period presentation of net loss from real estate. Beginning in the third quarter of 2023, the components of net loss from real estate, inclusive of rental income and other real estate income and interest expense, mortgages payable on real estate, depreciation and amortization and other real estate expenses, are presented as total net loss from real estate on the Company's condensed consolidated statements of operations. Previously, rental income, other real estate income and total income from real estate was presented in other income (loss) and interest expense, mortgages payable on real estate, depreciation and amortization, other real estate expenses and total expenses related to real estate were presented in general, administrative and operating expenses on the Company's condensed consolidated statements of operations.

Also beginning in the third quarter of 2023, unrealized gains (losses) and realized gains (losses) on derivative instruments are presented in gains (losses) on derivative instruments, net on the Company's condensed consolidated statements of operations. Previously, unrealized gains (losses) on derivative instruments were presented in unrealized gains (losses), net and realized gains (losses) on derivative instruments were presented in realized gains (losses), net on the Company's condensed consolidated statements of operations.

Principles of Consolidation and Variable Interest Entities

The accompanying condensed consolidated financial statements of the Company include the accounts of all its subsidiaries which are majority-owned, controlled by the Company or a VIE where the Company is the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in consolidation (see Note 7).

A VIE is an entity that lacks one or more of the characteristics of a voting interest entity. A VIE is defined as an entity in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The Company consolidates a VIE in accordance with ASC 810, Consolidation ("ASC 810") when it is the primary beneficiary of such VIE, herein referred to as a Consolidated VIE. As primary beneficiary, the Company has both the power to direct the activities that most significantly impact the economic performance of the VIE and a right to receive benefits or absorb losses of the entity that could be potentially significant to the VIE. The Company is required to reconsider its evaluation of whether to consolidate a VIE each reporting period, based upon changes in the facts and circumstances pertaining to the VIE.

The Company evaluates the initial consolidation of each Consolidated VIE, which includes a determination of whether the VIE constitutes the definition of a business in accordance with ASC 805, Business Combinations ("ASC 805"), by considering if substantially all of the fair value of the gross assets within the VIE are concentrated in either a single identifiable asset or group of single identifiable assets. Upon consolidation, the Company recognizes the assets acquired, the liabilities assumed, and any third-party ownership of membership interests as non-controlling interest as of the consolidation or acquisition date, measured at their relative fair values (see Note 7). Non-controlling interest in Consolidated VIEs is adjusted prospectively for its share of the allocation of income or loss and equity contributions and distributions from each respective Consolidated VIE. The third-party owners of certain of the non-controlling interests in Consolidated VIEs have the ability to sell their ownership interests to the Company, at their election, subject to certain conditions. The Company has classified these third-party ownership interests as redeemable non-controlling interest in Consolidated VIEs in mezzanine equity on the accompanying condensed consolidated balance sheets.

Collateralized Debt Obligations

The Company records collateralized debt obligations used to permanently finance the residential loans held in Consolidated SLST, a portion of the Company's net investment in Consolidated SLST and the Company's residential loans held in securitization trusts as debt on the accompanying condensed consolidated balance sheets. For financial reporting purposes, the loans and investment securities held as collateral for these obligations are recorded as assets of the Company. The Company has elected the fair value option pursuant to ASC 825, Financial Instruments ("ASC 825") with respect to the CDOs issued by Consolidated SLST and CDOs issued by the Company after January 1, 2024. The Company elected the fair value option for CDOs issued by the Company after January 1, 2024 because the Company determined that such presentation represents the underlying economics of the respective financing. Changes in fair value of CDOs subject to the fair value election are recorded in current period earnings in unrealized gains (losses), net on the accompanying condensed consolidated statements of operations. Interest expense on such CDOs is recorded based on the current stated interest rate and outstanding principal balance in effect and is included in interest expense on the accompanying condensed consolidated statements of operations. In accordance with ASC 825, costs associated with the issuance of CDOs subject to the fair value election are recognized in earnings as they are incurred and are included in debt issuance costs on the accompanying condensed consolidated statements of operations.

Senior Unsecured Notes – On April 27, 2021, the Company issued its 5.75% Senior Notes due 2026 to originate new investments, repay outstanding indebtedness and for general corporate purposes. The Company evaluated the call option feature of these notes for embedded derivatives in accordance with ASC 815, Derivatives and Hedging ("ASC 815") and determined that the call option feature should not be bifurcated from the notes.

On June 28, 2024, the Company issued its 9.125% Senior Notes due 2029 (the "9.125% Senior Notes") for general corporate purposes, which included acquiring single-family residential assets. The Company evaluated the call option feature of these notes for embedded derivatives in accordance with ASC 815 and determined that the call option feature should not be bifurcated from the notes. The Company has elected the fair value option pursuant to ASC 825 with respect to the 9.125% Senior Notes because the Company determined that such presentation represents the underlying economics of the respective financing. Changes in fair value of the 9.125% Senior Notes are recorded in current period earnings in unrealized gains (losses), net on the accompanying condensed consolidated statements of operations (or other comprehensive income, to the extent the change results from a change in instrument-specific credit risk). Interest expense on such 9.125% Senior Notes is recorded based on the current stated interest rate and outstanding principal balance in effect and is included in interest expense on the accompanying condensed consolidated statements of operations. In accordance with ASC 825, costs associated with the issuance of the 9.125% Senior Notes are recognized in earnings as they are incurred and are included in debt issuance costs on the accompanying condensed consolidated statements of operations.

Summary of Recent Accounting Pronouncements

In December 2023, the FASB issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"). ASU 2023-09 requires enhanced disclosures in connection with an entity's effective tax rate reconciliation and additional disclosures about income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The Company expects that the adoption of ASU 2023-09 will result in additional income tax disclosures in its notes to consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis. The amendments also require companies with a single reportable segment to provide all disclosures required by ASU 2023-07 as well as existing segment disclosures in accordance with ASC 280. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company expects that the adoption of ASU 2023-07 will result in additional disclosures in its notes to consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). ASU 2020-04 provides optional expedients and exceptions to GAAP requirements for modifications to debt agreements, leases, derivatives and other contracts, related to the expected market transition from LIBOR, and certain other floating rate benchmark indices, or collectively, IBORs, to alternative reference rates. ASU 2020-04 generally considers contract modifications related to reference rate reform to be an event that does not require contract remeasurement at the modification date nor a reassessment of a previous accounting determination. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 ("ASU 2022-06"), which allows ASU 2020-04 to be adopted and applied prospectively to contract modifications made on or before December 31, 2024. In light of the cessation of the publication of LIBOR after June 30, 2023, the Company’s material contracts that were indexed to LIBOR have been amended to transition to an alternative benchmark and any other unmodified agreements that incorporate LIBOR as the referenced rate have provisions in place that provide for identification of an alternative benchmark or specify an alternative benchmark, or by operation of law specify an alternative benchmark, to LIBOR upon its phase-out.

Fair Value of Financial Instruments

The Company has established and documented processes for determining fair values. Fair value is based upon quoted market prices, where available. If listed prices or quotes are not available, then fair value is based upon internally developed models that primarily use inputs that are market-based or independently-sourced market parameters, including interest rate yield curves.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of valuation hierarchy are defined as follows:

Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or 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 the fair value measurement.

The following describes the valuation methodologies used for the Company’s financial instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy.

a.Residential Loans Held in Consolidated SLST – Residential loans held in Consolidated SLST are carried at fair value and classified as Level 3 fair values. In accordance with the practical expedient in ASC 810, the Company determines the fair value of residential loans held in Consolidated SLST based on the fair value of the CDOs issued by the respective securitizations and its investment in the securitizations (eliminated in consolidation in accordance with GAAP), as the fair value of these instruments is more observable.

The investment securities (eliminated in consolidation in accordance with GAAP) that we own in the securitizations are generally illiquid and trade infrequently. As such, they are classified as Level 3 in the fair value hierarchy. The fair valuation of these investment securities is determined based on an internal valuation model that considers expected cash flows from the underlying loans and yields required by market participants. The significant unobservable inputs used in the measurement of these investments are projected losses within the pool of loans and a discount rate. The discount rate used in determining fair value incorporates default rate, loss severity, prepayment rate and current market interest rates. Significant increases or decreases in these inputs would result in a significantly lower or higher fair value measurement.

b.Residential Loans and Residential Loans Held in Securitization Trusts – The Company’s acquired residential loans are recorded at fair value and classified as Level 3 in the fair value hierarchy. The fair value for residential loans is determined using valuations obtained from a third party that specializes in providing valuations of residential loans. The valuation approach depends on whether the residential loan is considered performing, re-performing or non-performing at the date the valuation is performed.

For performing and re-performing loans, estimates of fair value are derived using a discounted cash flow model, where estimates of cash flows are determined from scheduled payments for each loan, adjusted using forecast prepayment rates, default rates and rates for loss upon default. For non-performing loans, asset liquidation cash flows are derived based on the estimated time to liquidate the loan, expected liquidation costs and home price appreciation. Estimated cash flows for both performing and non-performing loans are discounted at yields considered appropriate to arrive at a reasonable exit price for the asset. Indications of loan value such as actual trades, bids, offers and generic market color may be used in determining the appropriate discount yield.

The Company independently calculates the fair value of residential loans based on discounted cash flows using an internal pricing model to validate all third party valuations of residential loans. The Company has established thresholds to compare internally generated prices with independent third-party prices and any differences that exceed the thresholds are reviewed both internally and with the third-party pricing service. The Company reconciles and resolves all pricing differences in excess of the thresholds before a final price is established.

c.Preferred Equity and Mezzanine Loan Investments – Fair value for preferred equity and mezzanine loan investments is determined by both market comparable pricing and discounted cash flows. The discounted cash flows are based on the underlying estimated cash flows and estimated changes in market yields. The fair value also reflects consideration of changes in credit risk since origination or time of initial investment. This fair value measurement is generally based on unobservable inputs and, as such, is classified as Level 3 in the fair value hierarchy.

d.Investment Securities Available for Sale – The Company determines the fair value of its Agency RMBS and non-Agency RMBS based on discounted cash flows utilizing an internal pricing model. The methodology considers the characteristics of the particular security and its underlying collateral, which are observable inputs. These inputs include, but are not limited to, delinquency status, coupon, loan-to-value ("LTV"), historical performance, periodic and life caps, collateral type, rate reset period, seasoning, prepayment speeds and credit enhancement levels. The Company also considers several observable market data points, including prices obtained from third-party pricing services or dealers who make markets in similar financial instruments, trading activity, and dialogue with market participants. Third-party pricing services typically incorporate commonly used market pricing methods, trading activity observed in the marketplace and other data inputs similar to those used in the Company's internal pricing model. The Company has established thresholds to compare internally generated prices with independent third-party prices and any differences that exceed the thresholds are reviewed both internally and with the third-party pricing service. The Company reconciles and resolves all pricing differences in excess of the thresholds before a final price is established.

The Company determines the fair value of its U.S. Treasury securities using a third-party pricing service that compiles prices from various sources or using pricing models that consider observable market data to determine the fair value of identical or similar securities.

The Company’s investment securities available for sale are valued based upon readily observable market parameters and are classified as Level 2 fair values.

e.Equity Investments – Fair value for equity investments is determined (i) by the valuation process for preferred equity and mezzanine loan investments as described in c. above or (ii) using weighted multiples of origination volume and earnings before taxes, depreciation and amortization of the entity and the net asset value ("NAV") of the equity investment entity. These fair value measurements are generally based on unobservable inputs and, as such, are classified as Level 3 in the fair value hierarchy.

f.Derivative Instruments – The fair values of the Company's interest rate cap agreements are measured using models developed by either third-party pricing providers or the respective counterparty that use the market-standard methodology of discounting the future expected cash receipts which would occur if floating interest rates rise above the strike rate of the caps. The floating interest rates used in the calculation of projected receipts on the interest rate caps are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. The inputs used in the valuation of interest rate caps fall within Level 2 of the fair value hierarchy.

The Company's interest rate swaps and credit default swaps are classified as Level 2 fair values and are measured using valuations reported by the respective central clearing houses. The derivatives are presented net of variation margin payments pledged or received.

The Company obtains additional third-party valuations for interest rate swaps, credit default swaps and interest rate cap agreements. The Company has established thresholds to compare different independent third-party prices and any differences that exceed the thresholds are reviewed both internally and with the third-party pricing services. The Company reconciles and resolves all pricing differences in excess of the thresholds before a final price is established.

g.Collateralized Debt Obligations – CDOs issued by Consolidated SLST are classified as Level 3 fair values for which fair value is determined by considering several market data points, including prices obtained from third-party pricing services or dealers who make markets in similar financial instruments. The third-party pricing service or dealers incorporate common market pricing methods, including a spread measurement to the Treasury curve or interest rate swap curve as well as underlying characteristics of the particular security. They will also consider contractual cash payments and yields expected by market participants.

Refer to a. above for a description of the fair valuation of CDOs issued by Consolidated SLST that are eliminated in consolidation.

Fair value for CDOs issued by the Company's residential loan securitizations and non-Agency RMBS re-securitization is determined by the valuation process for investment securities available for sale as described in d. above and, as such, are classified as Level 2 fair values.

h.Senior unsecured notes – The Company's 9.125% Senior Notes are valued using pricing models that consider observable market data to determine the fair value of identical or similar securities and are classified as Level 2 fair values.

Management reviews all prices used in determining fair value to ensure they represent current market conditions. This review includes surveying similar market transactions and comparisons to interest pricing models as well as offerings of like securities by dealers. Any changes to the valuation methodology are reviewed by management to ensure the changes are appropriate. As markets and products develop and the pricing for certain products becomes more transparent, the Company continues to refine its valuation methodologies. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of 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 each reporting date, which may include periods of market dislocation, during which time price transparency may be reduced. This condition could cause the Company’s financial instruments to be reclassified from Level 2 to Level 3 in future periods.
