Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements presented herein are as of March 31, 2026 and December 31, 2025, and for the three months ended March 31, 2026 and 2025. These interim unaudited consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") and GAAP. Certain disclosures typically included in our annual financial statements may be condensed or omitted from these interim financial statements, as permitted. The disclosures included in these interim financial statements are intended to be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. In the opinion of management, all normal and recurring adjustments have been made to present fairly the financial condition of the Company at March 31, 2026 and results of operations for all periods presented. The results of operations for the three months ended March 31, 2026 should not be construed as indicative of the results to be expected for the full year. During the three months ended March 31, 2026, we established Aspire Mortgage Banking as a new reportable segment to separately disclose financial results for our expanded-credit residential mortgage platform, which was previously included within the Sequoia Mortgage Banking segment. Aspire Mortgage Banking includes our non-QM loan conduit, which focuses on loans and investments under expanded underwriting criteria. This change had no impact on the consolidated financial statements and all prior period amounts were conformed to the current presentation. See Note 4 for further discussion on our reportable segments. During the same period, we began allocating our preferred stock dividend expense as well as our corporate financing costs, comprised of interest expense on our unsecured promissory notes, trust preferred securities, convertible debt, and senior notes, to our operating or reportable segments for informational purposes. Corporate and other activities that are not directly attributable to the Company’s operating segments are included in Corporate/Other. This change had no impact on the consolidated financial statements and all prior period amounts were conformed to the current presentation. During the second quarter of 2025, we established Legacy Investments as a new reportable segment to separately disclose financial results for assets that are no longer aligned with our core strategic objectives. These assets include our legacy unsecuritized bridge and term portfolios, residential re-performing loan securities and other non-core legacy assets that are intended for sale, runoff, or other forms of disposition as part of our ongoing strategic realignment. See Note 4 for further discussion on our reportable segments. Principles of Consolidation Our consolidated financial statements include the accounts of the entities where the Company has a controlling financial interest. The method for determining whether a controlling financial interest exists varies depending on whether the entity is a VIE. The Company has a controlling financial interest in and consolidates a VIE when the firm has a variable interest or interests that provide it with (i) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits for the VIE that could potentially be significant to the VIE. See Note 16 for further information about VIEs. For entities that are not VIEs, we have a controlling financial interest in entities where we hold a majority of the voting rights. We use the equity method to account for our interest in entities in which we do not have a controlling financial interest, but over which we have significant influence. For financial reporting purposes, we consolidate the assets and liabilities of certain entities formed in connection with the securitization of our loans and Home Equity Investments ("HEI"), which we have determined to be VIEs and in which we have a controlling financial interest. The underlying loans owned at the consolidated securitization entities are shown under residential consumer loans and residential investor loans on our consolidated balance sheets. In our consolidated statements of income, we record interest income on the loans owned at these entities and interest expense on the ABS issued by these entities as well as fair value changes, other income and expenses associated with these entities' activities. The Asset-Backed securities (“ABS”) issued to third parties by these entities are shown under ABS issued. See Note 17 for further discussion on ABS issued. The underlying HEI at the consolidated HEI securitization entity are shown under Home equity investments on our consolidated balance sheets and the associated fair value changes and interest expense associated with ABS issued are shown under HEI income, net on our consolidated statements of (loss) income. See Note 10 for further discussion on HEI. We also consolidate two partnerships ("Servicing Investment" entities) through which we have invested in servicing-related assets. We maintain an 80% ownership interest in each entity and have determined that we are the primary beneficiary of these partnerships. We account for the co-investors' interests as non-controlling interests, see Note 15 for further discussion. See Note 16 for further discussion on Principles of consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates and assumptions.
