Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) Basis of Presentation and Consolidation On April 4, 2022, the Company effected a one-for-four reverse stock split of its issued and outstanding shares of common stock (the “Reverse Stock Split”). Accordingly, all share and per share data included in these consolidated financial statements and notes thereto have been adjusted retroactively to reflect the impact of the Reverse Stock Split. The interim unaudited consolidated financial statements of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted in accordance with these SEC rules and regulations. Management believes that the disclosures included in these interim unaudited consolidated financial statements are adequate to make the information presented not misleading. The accompanying unaudited consolidated financial statements should 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, 2022. In the opinion of management, all normal and recurring adjustments necessary to present fairly the financial condition of the Company at June 30, 2023 and results of operations for all periods presented have been made. The results of operations for the three and six months ended June 30, 2023 should not be construed as indicative of the results to be expected for the full year. The accompanying consolidated financial statements of the Company 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. 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 differ from those estimates, which could materially impact the Company’s results of operations and its financial condition. Management has made significant estimates in several areas: impairment, valuation allowances and loss allowances on residential whole loans (see Note 3), certain securities designated as available-for- sale (“AFS”) (see Note 4) and certain Other assets (see Note 5), valuation of Securities, at fair value (see Notes 4 and 13), income recognition and valuation of residential whole loans (see Notes 3 and 13), valuation of financing agreements (Notes 6 and 13), and valuation of derivative instruments (see Notes 5(d) and 13). In addition, estimates are used in the determination of taxable income used in the assessment of REIT compliance and contingent liabilities for related taxes, penalties and interest (see Note 8). Actual results could differ from those estimates. The consolidated financial statements of the Company include the accounts of all subsidiaries. All intercompany accounts and transactions have been eliminated. In addition, the Company consolidates entities established to facilitate transactions related to the acquisition and securitization of residential whole loans. Certain prior period amounts have been reclassified to conform to the current period presentation. (b) Residential Whole Loans (including Residential Whole Loans transferred to consolidated VIEs) Residential whole loans included in the Company’s consolidated balance sheets are primarily comprised of pools of fixed- and adjustable-rate residential mortgage loans acquired through consolidated trusts in secondary market transactions or originated by Lima One. The accounting model utilized by the Company is determined at the time each loan package is initially acquired. Prior to the second quarter of 2021, the Company typically elected the fair value option on loans that were 60 or more days delinquent at purchase (“Purchased Non-performing Loans”). Purchased Credit Deteriorated Loans (i.e., mortgage loans in which the underlying borrower had a delinquency status of less than 60 days at the acquisition date) acquired prior to the second quarter of 2021 are typically held at carrying value. Purchased Performing Loans (as described below) acquired prior to the second quarter of 2021 are also typically held at carrying value, but the accounting methods for income recognition and determination and measurement of any required credit loss reserves (as discussed below) differ from those used for Purchased Credit Deteriorated Loans held at carrying value. Starting in the second quarter of 2021, the Company began to elect the fair value option for all loans acquired, irrespective of borrower delinquency status at acquisition. The accounting model initially applied to loan acquisitions is not permitted to be subsequently changed. Consequently, the Company is not permitted to retroactively apply fair value accounting to loans held at carrying value acquired in periods prior to the second quarter of 2021. The Company’s residential whole loans pledged as collateral against financing agreements are included in the consolidated balance sheets with amounts pledged disclosed in Note 6. Purchases and sales of residential whole loans that are subject to an extended period of due diligence that crosses a reporting date are recorded in the Company’s balance sheet at amounts reflecting management’s current estimate of assets that will be acquired or disposed at the closing of the transaction. This estimate is subject to revision at the closing of the transaction, pending the outcome of due diligence performed prior to closing. Residential whole loans purchased under flow arrangements with loan origination partners are generally recorded at the transaction settlement date. Recorded amounts of residential whole loans for which the closing of the purchase transaction is yet to occur are not eligible to be pledged as collateral against any financing agreement until the closing of the purchase transaction. Interest income, credit related losses and changes in the fair value of loans held at fair value are recorded post settlement for acquired loans and until transaction settlement for sold loans (see Notes 3, 6, 13 and 14). Purchased Performing Loans Acquisitions of Purchased Performing Loans to date (which include loans purchased from third parties or loans originated by Lima One) have been primarily comprised of: (i) loans to finance (or refinance) one-to-four family residential properties that are not considered to meet the definition of a “Qualified Mortgage” in accordance with guidelines adopted by the Consumer Financial Protection Bureau (“Non-QM loans”), (ii) short-term business purpose loans collateralized by residential and multi-family properties made to non-occupant borrowers that intend to rehabilitate and sell the properties (“Transitional loans” or “TL”) (also sometimes referred to as “Rehabilitation loans” or “Fix and Flip loans”), (iii) business purpose loans to finance (or refinance) non-owner occupied one-to-four family residential properties that are rented to one or more tenants (“Single-family rental loans”), (iv) loans on investor properties that conform to the standards for purchase by a federally chartered corporation, such as the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”) (“Agency eligible investor loans”), and (v) previously originated loans secured by residential real estate that is generally owner occupied (“Seasoned performing loans”). Purchased Performing Loans are initially recorded at their purchase price (or amount funded for originated loans). Interest income on Purchased Performing Loans acquired at par is accrued based on each loan’s current interest bearing balance and current interest rate. Interest income on such loans acquired at a premium/discount to par is recorded each period based on the contractual coupon net of any amortization of premium or accretion of discount, adjusted for actual prepayment activity. For loans acquired with related servicing rights retained by the seller, interest income is reported net of related serving costs. For Purchased Performing Loans acquired prior to the second quarter of 2021 for which the fair value option was not elected, an allowance for credit losses is recorded at acquisition, and maintained on an ongoing basis, for all losses expected over the life of the respective loan. Any required credit loss allowance would reduce the net carrying value of the loan with a corresponding charge to earnings, and may increase or decrease over time. Significant judgments are required in determining any allowance for credit loss, including assumptions regarding the loan cash flows expected to be collected, the value of the underlying collateral and the ability of the Company to collect on any other forms of security, such as a personal guaranty provided either by the borrower or an affiliate of the borrower. Income recognition is suspended, and interest accruals are reversed against income, for loans at the earlier of the date on which payments become 90 days past due or when, in the opinion of management, a full recovery of income and principal becomes doubtful (i.e., such loans are placed on nonaccrual status). For nonaccrual loans, interest income is recorded under the cash basis method as interest payments are received. Interest accruals are resumed when the loan becomes contractually current. A loan is written off when it is no longer realizable and/or it is legally discharged. Modified loans are considered “troubled debt restructurings” if the Company grants a concession to a borrower who is experiencing financial difficulty (including the interpretation of this definition set forth in OCC Bulletin 2020-35). Charge-offs to the allowance for loan losses occur when losses are confirmed through the receipt of cash or other consideration from the completion of a sale; when a modification or restructuring takes place in which we grant a concession to a borrower or agree to a discount in full or partial satisfaction of the loan; when we take ownership and control of the underlying collateral in full satisfaction of the loan; when loans are reclassified as other investments; or when significant collection efforts have ceased and it is highly likely that a loss has been realized. The aggregate allowance for credit losses is equal to the sum of the losses expected over the life of each respective loan. Expected losses are generally calculated based on the estimated probability of default and loss severity of loans in the portfolio, which involves projecting each loan’s expected cash flows based on their contractual terms, expected prepayments, and estimated default and loss severity rates. The results were not discounted. The default and severity rates were estimated based on the following steps: (i) obtained the Company’s historical experience through an entire economic cycle for each loan type or, to the extent the Company did not have sufficient historical loss experience for a given loan type, publicly available data derived from the historical loss experience of certain banks, which data the Company believes is generally representative of its portfolio, (ii) obtained historical economic data (U.S. unemployment rates and home price appreciation) over the same period, and (iii) estimated default and severity rates during three distinct future periods based on historical default and severity rates during periods when economic conditions similar to those forecasted were experienced. The default and severity rates were applied to the estimated amount of loans outstanding during each future period, based on contractual terms and expected prepayments. Expected prepayments are estimated based on historical experience and current and expected future economic conditions, including market interest rates. The three periods were as follows: (i) a one-year forecast of economic conditions based on U.S. unemployment rates and home price appreciation, followed by (ii) a two-year “reversion” period during which economic conditions (U.S. unemployment rates and home price appreciation) are projected to revert to historical averages on a straight line basis, followed by (iii) the remaining life of each loan, during which period economic conditions (U.S. unemployment rates and home price appreciation) are projected to equal historical averages. In addition, a liability is established (and recorded in Other Liabilities) each period using a similar methodology for committed but undrawn loan amounts. The Company forecasts future economic conditions based on forecasts provided by an external preparer of economic forecasts, as well as its own knowledge of the market and its portfolio. The Company may consider multiple scenarios and select the one that it believes results in the most reasonable estimate of expected losses. The Company may apply qualitative adjustments to these results as further described in Note 3. For certain loans where foreclosure has been deemed to be probable, loss estimates are based on whether the value of the underlying collateral is sufficient to recover the carrying value of the loan. This methodology has not changed significantly from the calculation of the allowance for credit losses in prior periods. Purchased Credit Deteriorated Loans The Company has elected to account for these loans as credit deteriorated, as they have experienced a deterioration in credit quality since origination and prior to our purchase and were acquired at discounted prices that reflect, in part, the impaired credit history of the borrower. Substantially all of these loans have previously experienced payment delinquencies and the amount owed may exceed the value of the property pledged as collateral. Consequently, these loans generally have a higher likelihood of default than newly originated mortgage loans with loan-to-value ratios (“LTVs”) of 80% or less to creditworthy borrowers. The Company believes that amounts paid to acquire these loans represent fair market value at the date of acquisition. Loans considered credit deteriorated are initially recorded at their purchase price on a net basis, after establishing an initial allowance for credit losses (their initial cost basis is equal to their purchase price plus the initial allowance for credit losses). Subsequent to acquisition, the gross recorded amount for these loans reflects the initial cost basis, plus accretion of interest income, less principal and interest cash flows received. Purchased Credit Deteriorated Loans acquired prior to the second quarter of 2021, or where the fair value option was not otherwise elected, are presented on the Company’s consolidated balance sheets at carrying value, which reflects the recorded cost basis reduced by any allowance for credit losses. Interest income on such loans purchased is recorded each period based on the contractual coupon net of amortization of the difference between their cost basis and unpaid principal balance (“UPB”), subject to the Company’s nonaccrual policy. Residential Whole Loans at Fair Value Certain of the Company’s residential whole loans are presented at fair value on its consolidated balance sheets as a result of a fair value election made at the time of acquisition. Prior to the second quarter of 2021, this accounting election was made primarily on Purchased Non-performing Loans. Starting in the second quarter of 2021, the Company made the fair value election on all loan acquisitions, which, to date, have been comprised exclusively of Purchased Performing Loans (including loans originated by Lima One since its consolidation). The Company generally considers accounting for these loans at fair value to be more reflective of the expected pattern of returns from these loans under current economic conditions. The Company determines the fair value of its residential whole loans held at fair value after considering portfolio valuations obtained from third-parties that specialize in providing valuations of residential mortgage loans and trading activity observed in the marketplace. Subsequent changes in fair value are reported in current period earnings and presented in Net (loss)/gain on residential whole loans measured at fair value through earnings on the Company’s consolidated statements of operations. Interest income is recorded on these loans based on their yield and is presented as part of interest income in the Company’s consolidated statements of operations. Cash outflows associated with loan-related advances made by the Company on behalf of the borrower are included in the basis of the loan and are reflected in unrealized gains or losses reported each period. Income and costs associated with originating loans on which the fair value option was elected are recorded in other income and expense respectively in the period in which they are earned or incurred. (c) Securities, at Fair Value Residential Mortgage Securities The Company has invested in residential MBS that are issued or guaranteed as to principal and/or interest by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government, such as the Government National Mortgage Association (“Ginnie Mae”) (collectively, “Agency MBS”), and residential MBS that are not guaranteed by any agency of the U.S. Government or any federally chartered corporation (“Non-Agency MBS”). In addition, the Company has investments in CRT securities that are issued by or sponsored by Fannie Mae and Freddie Mac. The coupon payments on CRT securities are paid by the issuer and the principal payments received are dependent on the performance of loans in either a reference pool or an actual pool of loans. As the loans in the underlying pool are paid, the principal balance of the CRT securities is paid. As an investor in a CRT security, the Company may incur a principal loss if the performance of the actual or reference pool loans results in either an actual or calculated loss that exceeds the credit enhancement of the security owned by the Company. Term Notes Backed by MSR Collateral The Company has invested in term notes that are issued by special purpose vehicles (“SPV”) that have acquired rights to receive cash flows representing the servicing fees and/or excess servicing spread associated with certain MSRs. The Company considers payment of principal and interest on these term notes to be largely dependent on the cash flows generated by the underlying MSRs as this impacts the cash flows available to the SPV that issued the term notes. Credit risk borne by the holders of the term notes is also mitigated by structural credit support in the form of over-collateralization. Credit support is also provided by a corporate guarantee from the ultimate parent or sponsor of the SPV that is intended to provide for payment of interest and principal to the holders of the term notes should cash flows generated by the underlying MSRs be insufficient. Designation Securities that the Company generally intends to hold until maturity, but that it may sell from time to time as part of the overall management of its business, are designated as AFS. Such securities, which include term notes backed by MSR collateral and certain CRT securities, are carried at their fair value with unrealized gains and losses excluded from earnings (except when an allowance for loan losses is recognized, as discussed below) and reported in accumulated other comprehensive income (“AOCI”), a component of Stockholders’ Equity. Upon the sale of an AFS security, any unrealized gain or loss is reclassified out of AOCI to earnings as a realized gain or loss using the specific identification method. The Company has elected the fair value option for its Agency and Non-Agency MBS and certain of its CRT securities. These securities are carried at their fair value with changes in fair value included in earnings for the period and reported in Other Income, net on the Company’s consolidated statements of operations. Revenue Recognition, Premium Amortization and Discount Accretion Interest income on securities is accrued based on their outstanding principal balance and their contractual terms. Premiums and discounts associated with MBS assessed as high credit quality at the time of purchase are amortized into interest income over the life of such securities using the effective yield method. Adjustments to premium amortization are made for actual prepayment activity. Determination of Fair Value for Securities In determining the fair value of the Company’s securities, management considers a number of observable market data points, including prices obtained from pricing services, brokers and repurchase agreement counterparties, dialogue with market participants, as well as management’s observations of market activity (see Note 13). For term notes backed by MSR collateral, other factors taken into consideration include estimated changes in fair value of the related underlying MSR collateral, as applicable, and the financial performance of the ultimate parent or sponsoring entity of the issuer, which has provided a guarantee that is intended to provide for payment of interest and principal to the holders of the term notes should cash flows generated by the related underlying MSR collateral be insufficient. Allowance for credit losses When the fair value of an AFS security is less than its amortized cost at the balance sheet date, the security is considered impaired. The Company assesses its impaired securities, as well as securities for which a credit loss allowance had been previously recorded, on at least a quarterly basis and determines whether any changes to the allowance for credit losses are required. If the Company intends to sell an impaired security, or it is more likely than not that it will be required to sell the impaired security before its anticipated recovery, then the Company must recognize a write-down through charges to earnings equal to the entire difference between the investment’s amortized cost and its fair value at the balance sheet date. If the Company does not expect to sell an impaired security, only the portion of the impairment related to credit losses is recognized through a loss allowance charged to earnings with the remainder recognized through AOCI on the Company’s consolidated balance sheets. Impairments recognized through other comprehensive income/(loss) (“OCI”) do not impact earnings. Credit loss allowances are subject to reversal through earnings resulting from improvements in expected cash flows. The determination as to whether to record (or reverse) a credit loss allowance is subjective, as such determinations are based on factual information available at the time of assessment as well as the Company’s estimates of future performance and cash flow projections. As a result, the timing and amount of losses constitute material estimates that are susceptible to significant change (see Note 4). Balance Sheet Presentation The Company’s securities pledged as collateral against financing agreements are included on the consolidated balance sheets with the fair value of the securities pledged disclosed in Note 6. Purchases and sales of securities are recorded on the trade date. (d) Cash and Cash Equivalents Cash and cash equivalents include cash on deposit with financial institutions and investments in money market funds, all of which have original maturities of three months or less. Cash and cash equivalents may also include cash pledged as collateral to the Company by its financing counterparties as a result of reverse margin calls (i.e., margin calls made by the Company). The Company did not hold any cash pledged by its counterparties at June 30, 2023 and December 31, 2022. At June 30, 2023 and December 31, 2022, the Company had cash and cash equivalents of $329.4 million and $334.2 million, respectively. At June 30, 2023, the Company had $224.4 million of investments in overnight money market funds, which are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any other government agency. As of December 31, 2022, the Company had $267.1 million worth of investments in overnight money market funds. In addition, deposits in FDIC insured accounts generally exceed insured limits (see Notes 6 and 13). (e) Restricted Cash Restricted cash primarily represents the Company’s cash collections held in connection with certain of the Company’s financing agreements, interest rate swap agreements (“Swaps”) and/or loan servicing activities that are not available to the Company for general corporate purposes. Restricted cash may be applied against amounts due to financing agreements and/or Swap counterparties, or may be returned to the Company when the related collateral requirements are exceeded or at the maturity of financing agreements and/or Swaps. The Company had aggregate restricted cash of $174.0 million and $159.9 million at June 30, 2023 and December 31, 2022, respectively (see Notes 5(d), 6 and 13). (f) Goodwill & Intangible Assets At June 30, 2023 and December 31, 2022, the Company had goodwill of $61.1 million, which represents the excess of the fair value of consideration paid over the fair value of net assets acquired in connection with the acquisition of Lima One, and other intangible assets of $9.6 million and $12.2 million, respectively (net of amortization), primarily comprised of customer relationships, non-competition agreements (fully amortized as of June 30, 2022), trademarks and trade names, and internally developed software recognized as part of the acquisition of Lima One (see Note 5(b)). The intangible assets are amortized over their expected useful lives, which ranged from one (g) Real Estate Owned (“REO”) REO represents real estate acquired by the Company, including through foreclosure, deed in lieu of foreclosure, or purchased in connection with the acquisition of residential whole loans. REO acquired through foreclosure or deed in lieu of foreclosure is initially recorded at fair value less estimated selling costs. REO acquired in connection with the acquisition of residential whole loans is initially recorded at its purchase price. Subsequent to acquisition, REO is reported, at each reporting date, at the lower of the current carrying amount or fair value less estimated selling costs and for presentation purposes is included in Other assets on the Company’s consolidated balance sheets. Changes in fair value that result in an adjustment to the reported amount of an REO property that has a fair value at or below its carrying amount are reported in Other Income, net on the Company’s consolidated statements of operations (see Note 5). (h) Leases and Depreciation Leases The Company records its operating lease liabilities and operating lease right-of-use assets on its consolidated balance sheets. The operating lease liabilities are equal to the present value of the remaining fixed lease payments (excluding real estate tax and operating expense escalations) discounted at the Company’s estimated incremental borrowing rate at the date of lease commencement, and the operating lease right-of-use assets are equal to the operating lease liabilities adjusted for lease incentives and initial direct costs. As lease payments are made, the operating lease liabilities are reduced to the present value of the remaining lease payments and the operating lease right-of-use assets are reduced by the difference between the lease expense (straight-lined over the lease term) and the theoretical interest expense amount (calculated using the incremental borrowing rate at the date of lease commencement). See Notes 5 and 9 for further discussion on leases. Leasehold Improvements, Real estate and Other Depreciable Assets Depreciation is computed on the straight-line method over the estimated useful life of the related assets or, in the case of leasehold improvements, over the shorter of the useful life or the lease term. Furniture, fixtures, computers and related hardware have estimated useful lives ranging from five (i) Loan Securitization and Other Debt Issuance Costs Loan securitization related costs are costs associated with the issuance of beneficial interests by consolidated VIEs and incurred by the Company in connection with various financing transactions completed by the Company. These costs may include underwriting, rating agency, legal, accounting and other fees. Such costs, which reflect deferred charges (unless the debt is recorded at fair value, as discussed below), are included on the Company’s consolidated balance sheets as a direct deduction from the corresponding debt liability. These deferred charges are amortized as an adjustment to interest expense using the effective interest method. For certain financing agreements, such costs are amortized over the shorter of the period to the expected or stated legal maturity of the debt instruments. The Company periodically reviews the recoverability of these deferred costs and, in the event an impairment charge is required, such amount will be included in Operating and Other Expense on the Company’s consolidated statements of operations. To the extent that the Company has elected the fair value option for the related debt liability, these costs are expensed at the closing of the transaction. (j) Financing Agreements The Company finances the majority of its residential mortgage assets with financing agreements that include repurchase agreements and other forms of collateralized financing. Under repurchase agreements, the Company sells assets to a lender and agrees to repurchase the same assets in the future for a price that is higher than the original sale price. The difference between the sale price that the Company receives and the repurchase price that the Company pays represents interest paid to the lender. Although legally structured as sale and repurchase transactions, the Company accounts for repurchase agreements as secured borrowings. Under its repurchase agreements and other forms of collateralized financing, the Company pledges its assets as collateral to secure the borrowing, in an amount which is equal to a specified percentage of the fair value of the pledged collateral, while the Company retains beneficial ownership of the pledged collateral. At the maturity of a repurchase financing, unless the repurchase financing is renewed with the same counterparty, the Company is required to repay the loan including any accrued interest and concurrently receives back its pledged collateral from the lender. With the consent of the lender, the Company may renew a repurchase financing at the then prevailing financing terms. Margin calls, whereby a lender requires that the Company pledge additional assets or cash as collateral to secure borrowings under its repurchase financing with such lender, are routinely experienced by the Company when the value of the assets pledged as collateral declines as a result of principal amortization and prepayments or due to changes in market interest rates, spreads or other market conditions. The Company also may make margin calls on counterparties when collateral values increase. Should a counterparty decide not to renew a financing arrangement at maturity, the Company must either refinance elsewhere or be in a position to satisfy the obligation. If, during the term of a financing, a lender should default on its obligation, the Company might experience difficulty recovering its pledged assets which could result in an unsecured claim against the lender for the difference between the amount loaned to the Company plus interest due to the counterparty and the fair value of the collateral pledged by the Company to such lender, including accrued interest receivable on such collateral (see Notes 6 and 13). The Company has elected the fair value option on certain of its financing agreements. These agreements are reported at their fair value, with changes in fair value being recorded in earnings each period (or other comprehensive income, to the extent the change results from a change in instrument specific credit risk), as further detailed in Note 6. Financing costs, including “up

Receivables [Abstract]
Residential Whole Loans	Residential Whole Loans Included on the Company’s consolidated balance sheets at June 30, 2023 and December 31, 2022 are approximately $8.1 billion and $7.5 billion, respectively, of residential whole loans generally arising from the Company’s interests in certain trusts established to acquire the loans and certain entities established in connection with its loan securitization transactions. The Company has assessed that these entities are required to be consolidated for financial reporting purposes. Starting in the second quarter of 2021, the Company elected the fair value option for all loan acquisitions, including loans originated by Lima One subsequent to its acquisition by the Company. Prior to the second quarter of 2021, the fair value option was typically elected only for Purchased Non-performing Loans.

As of December 31, 2022, Transitional loans includes $632.3 million of loans collateralized by multi-family properties with a weighted average term to maturity of 18 months and a weighted average LTV ratio of 64%. (2) Weighted average is calculated based on the interest bearing principal balance of each loan within the related category. For loans acquired with servicing rights released by the seller, interest rates included in the calculation do not reflect loan servicing fees. For loans acquired with servicing rights retained by the seller, interest rates included in the calculation are net of servicing fees. (3) LTV represents the ratio of the total unpaid principal balance of the loan to the estimated value of the collateral securing the related loan as of the most recent date available, which may be the origination date. For Transitional loans, the LTV presented is the ratio of the maximum unpaid principal balance of the loan, including unfunded commitments, to the estimated “after repaired” value of the collateral securing the related loan, where available. For certain Transitional loans, totaling $296.1 million and $223.2 million at June 30, 2023 and December 31, 2022, respectively, an after repaired valuation was not obtained and the loan was underwritten based on an “as is” valuation. The weighted average LTV of these loans based on the current unpaid principal balance and the valuation obtained during underwriting, is 69% and 70% at June 30, 2023 and December 31, 2022, respectively. Excluded from the calculation of weighted average LTV are certain low value loans secured by vacant lots, for which the LTV ratio is not meaningful. 60+ LTV has been calculated on a consistent basis. (4) Excludes loans for which no Fair Isaac Corporation (“FICO”) score is available. During the three months ended December 31, 2022, Agency eligible investor loans with an unpaid principal balance of $337.8 million were sold, realizing losses, before the impact of economic hedging gains and the reversal of previously recognized unrealized losses of $72.3 million. In addition, in the fourth quarter of 2022, the Agency eligible investor loan securitizations were deconsolidated from the Company’s financial statements which resulted in the de-recognition of Agency eligible investor loans with an unpaid principal balance of $598.0 million. No Residential whole loans were sold during the six months ended June 30, 2023 and 2022.

Such allowance is included in “Other liabilities” in the Company’s consolidated balance sheets (see Note 7). (2) Includes $35.2 million and $71.9 million of loans that were assessed for credit losses based on a collateral dependent methodology as of June 30, 2023 and 2022, respectively. (3) Includes $55.5 million and $63.8 million of loans that were assessed for credit losses based on a collateral dependent methodology as of June 30, 2023 and 2022, respectively. The Company’s estimates of expected losses that form the basis of the Allowance for Credit Losses include certain qualitative adjustments which have the effect of increasing expected loss estimates. These qualitative adjustments were determined based on a variety of factors, including differences between the Company’s loan portfolio and the loan portfolios represented by data available in regulatory filings of certain banks that are considered to have similar loan portfolios (available proxy data), and differences between current (and expected future) market conditions in comparison to market conditions that occurred in historical periods. Such differences include uncertainty with respect to any residual impact of the COVID-19 pandemic, anticipated inflation and increasing market interest rates, and heightened political uncertainty. The Company’s estimates of credit losses reflect the Company’s expectation that the performance of its portfolio will experience higher delinquencies and defaults compared to the performance in historical periods of portfolios included in the available proxy data. Estimates of credit losses under credit losses on financial instruments (“CECL”) are highly sensitive to changes in assumptions and current economic conditions have increased the difficulty of accurately forecasting future conditions. The amortized cost basis of Purchased Performing Loans on nonaccrual status as of June 30, 2023 and December 31, 2022 was $192.9 million and $195.1 million, respectively. The amortized cost basis of Purchased Credit Deteriorated Loans on nonaccrual status as of June 30, 2023 and December 31, 2022 was $71.8 million and $80.5 million, respectively. The fair value of Purchased Non-performing Loans on nonaccrual status as of June 30, 2023 and December 31, 2022 was $354.1 million and $413.1 million, respectively. During the three and six months ended June 30, 2023, the Company recognized $3.8 million and $7.4 million of interest income on loans on nonaccrual status, including $2.7 million and $5.3 million, respectively, on its portfolio of loans which were non-performing at acquisition. At June 30, 2023 and December 31, 2022, there were approximately $57.8 million and $71.7 million, respectively, of loans held at carrying value on nonaccrual status that did not have an associated allowance for credit losses because they were determined to be collateral dependent and the estimated fair value of the related collateral exceeded the carrying value of each loan, respectively. During the three months ended June 30, 2023, the Company granted two loan modifications in its carrying value loan portfolio which gave borrowers term extensions. The average increase in weighted average life was 13 months. As of June 30, 2023, the carrying value of these loans was approximately $165,000. As of June 30, 2023, these loans were both current.

For Transitional loans, the LTV presented is the ratio of the maximum unpaid principal balance of the loan, including unfunded commitments, to the estimated “after repaired” value of the collateral securing the related loan, where available. For certain Transitional loans, totaling $296.1 million at June 30, 2023, an after repaired valuation was not obtained and the loan was underwritten based on an “as is” valuation. The weighted average LTV of these loans based on the current unpaid principal balance and the valuation obtained during underwriting is 69% at June 30, 2023. Certain low value loans secured by vacant lots are categorized as LTV > 80%.

Investments, Debt and Equity Securities [Abstract]
Securities, at Fair Value	Securities, at Fair Value Agency MBS Agency MBS are guaranteed as to principal and/or interest by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government, such as Ginnie Mae. The following table presents certain information regarding the composition of our Agency MBS portfolio as of June 30, 2023: June 30, 2023 (Dollars in Thousands) Current Weighted Weighted Fair Weighted CPR (1) 30-Year Fixed Rate: 5.00% Coupon $ 77,662 100.2 % 98.0 % $ 76,147 3 6.0 % 5.50% Coupon 290,178 100.4 99.7 289,196 5 8.6 6.00% Coupon 30,629 100.8 101.0 30,948 0 — Total $ 398,469 100.4 % 99.5 % $ 396,291 4 8.0 % (1) Reflects the average of the 1 month CPR for the number of months the security was held during the most recent 3 month period. Term Notes Backed by MSR Collateral At June 30, 2023 and December 31, 2022, the Company had $91.2 million and $97.9 million, respectively, of term notes issued by SPVs that have acquired rights to receive cash flows representing the servicing fees and/or excess servicing spread associated with certain MSRs. Payment of principal and interest on these term notes is considered to be largely dependent on cash flows generated by the underlying MSRs, as this impacts the cash flows available to the SPV that issued the term notes. At June 30, 2023, these term notes had an amortized cost of $89.0 million, gross unrealized gains of $2.9 million and gross unrealized losses of $688,000, a weighted average yield of 16.2% and a weighted average term to maturity of 0.3 years. At December 31, 2022, the term notes had an amortized cost of $86.4 million, gross unrealized gains of approximately $11.5 million, a weighted average yield of 14.3% and a weighted average term to maturity of 0.8 years. The issuer of the notes has a one-time option to extend the maturity of the notes for an additional two years, subject to satisfaction of certain conditions. If the notes are extended, the issuer would also be subject to a step-up fee that would increase the return on the notes. CRT Securities CRT securities are debt obligations issued by or sponsored by Fannie Mae and Freddie Mac. The coupon payments on CRT securities are paid by the issuer and the principal payments received are dependent on the performance of loans in either a reference pool or an actual pool of loans.

Financing agreements held at fair value are reported at estimated fair value each period as a result of the Company’s fair value option election. The fair value option was not elected for financing agreements held at carrying value. Consequently, Total financing agreements as presented reflects a summation of balances reported at fair and carrying value. At June 30, 2023, the Company had $553.2 million of agreements with mark-to-market collateral provisions held at fair value, $440.1 million of agreements with non-mark-to-market collateral provisions held at fair value, and $3.1 billion of securitized debt held at fair value, with amortized cost bases of $553.2 million, $440.1 million, and $3.3 billion, respectively. At December 31, 2022, the Company had $884.5 million of agreements with mark-to-market collateral provisions held at fair value, $578.9 million of agreements with non-mark-to-market collateral provisions held at fair value, and $2.4 billion of securitized debt held at fair value, with amortized cost bases of $884.5 million, $578.9 million, and $2.6 billion, respectively. (2) Weighted average cost of funding reflects annualized quarter-to-date interest expense divided by average balance for the financing agreements. The cost of funding for the total financing agreements includes the impact of the net carry (the difference between swap interest income received and swap interest expense paid) on the Company’s Swaps. For the quarter ended June 30, 2023, this decreased the overall funding cost by 138 basis points, and for the quarter ended December 31, 2022, this decreased the overall funding cost by 84 basis points. The Company does not allocate the impact of the net carry by type of financing agreement.

The Company pledges securities or cash as collateral to its counterparties in relation to certain of its financing arrangements. The Company exchanges collateral with its counterparties based on changes in the fair value, notional amount and term of the associated financing arrangements and Swaps, as applicable. In connection with these margining practices, either the Company or its counterparty may be required to pledge cash or securities as collateral. When the Company’s pledged collateral exceeds the required margin, the Company may initiate a reverse margin call, at which time the counterparty may either return the excess collateral or provide collateral to the Company in the form of cash or equivalent securities. The Company’s assets pledged as collateral are also described in Notes 2(e) - Restricted Cash and 5(d) - Derivative Instruments. Certain of the Company’s financing arrangements and derivative transactions are governed by underlying agreements that generally provide for a right of setoff in the event of default or in the event of a bankruptcy of either party to the transaction. In the Company’s consolidated balance sheets, all balances associated with repurchase agreements are presented on a gross basis.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under the provisions of the Internal Revenue Code of 1986, as amended, (the “Code”), and the corresponding provisions of state law. The Company expects to operate in a manner that will enable it to satisfy the various requirements to maintain its status as a REIT for federal income tax purposes. In order to maintain its status as a REIT, the Company must, among other things, distribute at least 90% of its REIT taxable income (excluding net long-term capital gains) to stockholders in the timeframe permitted by the Code. As long as the Company maintains its status as a REIT, the Company will not be subject to regular federal income tax at the REIT level to the extent that it distributes 100% of its REIT taxable income (including net long-term capital gains) to its stockholders within the permitted timeframe. Should this not occur, the Company would be subject to federal taxes at prevailing corporate tax rates on the difference between its REIT taxable income and the amounts deemed to be distributed for that tax year. The Company’s objective is to distribute 100% of its REIT taxable income to its stockholders within the permitted timeframe. If the Company fails to distribute during each calendar year, or by the end of January following the calendar year in the case of distributions with declaration and record dates falling in the last three months of the calendar year, at least the sum of (i) 85% of its REIT ordinary income for such year, (ii) 95% of its REIT capital gain income for such year, and (iii) any undistributed taxable income from prior periods, the Company would be subject to a 4% nondeductible excise tax on the excess of the required distribution over the amounts actually distributed. To the extent that the Company incurs interest, penalties or related excise taxes in connection with its tax obligations, including as a result of its assessment of uncertain tax positions, such amounts will be included in Operating and Other Expense on the Company’s consolidated statements of operations. In addition, the Company has elected to treat certain of its subsidiaries as taxable REIT subsidiaries (“TRS”). In general, a TRS may hold assets and engage in activities that the Company cannot hold or engage in directly and generally may engage in any real estate or non-real estate-related business. Generally, a domestic TRS is subject to U.S. federal, state and local corporate income taxes. Given that a portion of the Company’s business is conducted through one or more TRS, the net taxable income earned by its domestic TRS, if any, is subject to corporate income taxation. To maintain the Company’s REIT election, no more than 20% of the value of the Company’s assets at the end of each calendar quarter may consist of stock or securities in TRS. For purposes of the determination of U.S. federal and state income taxes, the Company’s subsidiaries that elected to be treated as TRS record current or deferred income taxes based on differences (both permanent and timing) between the determination of their taxable income and net income under GAAP. Based on its analysis of any potentially uncertain tax positions, the Company concluded that it does not have any material uncertain tax positions that meet the relevant recognition or measurement criteria as of June 30, 2023, December 31, 2022 or June 30, 2022. As of the date of this filing, the Company’s tax returns for tax years 2019 through 2022 are open to examination. The tax effects of temporary differences that give rise to significant portions of net deferred tax assets (“DTAs”) recorded at the Company’s domestic TRS entities at June 30, 2023 and December 31, 2022 are presented in the following table: (In Thousands) June 30, 2023 December 31, 2022 Deferred tax assets (DTAs): Net operating loss and tax credit carryforwards $ 105,792 $ 97,655 Unrealized mark-to-market, impairments and loss provisions 14,787 12,609 Other realized / unrealized treatment differences (42,011) (28,620) Total deferred tax assets 78,568 81,644 Less: valuation allowance (78,568) (81,644) Net deferred tax assets $ — $ — Realization of the Company’s DTAs at June 30, 2023 is dependent on several factors, including generating sufficient taxable income prior to the expiration of net operating loss (“NOL”) carryforwards and generating sufficient capital gains in future periods prior to the expiration of capital loss carryforwards. The Company determines the extent to which realization of the deferred assets is not expected to be more likely than not and establishes a valuation allowance accordingly. No net deferred tax benefit was recorded by the Company for the three and six months ended June 30, 2023 and 2022, related to the net taxable losses in TRS entities, since a valuation allowance for the full amount of the associated deferred tax asset at the ends of those periods was recognized as its recovery was not considered more likely than not. The related NOL carryforwards generated prior to 2018 will begin to expire in 2037; those generated in 2018 and later can be carried forward indefinitely, until fully utilized. The Company’s estimate of net DTAs could change in future periods to the extent that actual or revised estimates of future taxable income change from current expectations. At June 30, 2023, the Company’s federal NOL carryforward from prior years was $382.6 million, which may be carried forward indefinitely. If certain substantial changes in the Company’s ownership occur, there could be an annual limitation on the amount of the carryforwards that can be utilized. The income tax provision/(benefit) is included in Other general and administrative expense in the Company’s consolidated statements of operations. The following table summarizes the Company’s income tax provision/(benefit) primarily recorded at the Company’s domestic TRS entities for the three and six months ended June 30, 2023 and 2022: Three Months Ended June 30, Six Months Ended June 30, (In Thousands) 2023 2022 2023 2022 Current provision/(benefit) Federal $ (286) $ 38 $ (420) $ 143 State (71) 184 (125) 209 Total current provision/(benefit) (357) 222 (545) 352 Deferred provision/(benefit) Federal — 120 589 270 State — 15 155 65 Total deferred provision/(benefit) — 135 744 335 Total provision/(benefit) $ (357) $ 357 $ 199 $ 687 The following is a reconciliation of the statutory federal tax rate to the Company’s effective tax rate at June 30, 2023 and 2022: Six Months Ended June 30, 2023 June 30, 2022 Federal statutory rate 21.0 % 21.0 % Non-taxable REIT income (dividends paid deduction) (32.6) % 2.9 % Other differences in taxable income (loss) from GAAP 23.0 % (17.0) % State and local taxes — % — % Change in valuation allowance on DTAs (11.0) % (7.1) % Effective tax rate 0.4 % (0.2) %

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders’ Equity (a) Preferred Stock 7.50% Series B Cumulative Redeemable Preferred Stock (“Series B Preferred Stock”) On April 15, 2013, the Company completed the issuance of 8.0 million shares of its Series B Preferred Stock with a par value of $0.01 per share, and a liquidation preference of $25.00 per share plus accrued and unpaid dividends, in an underwritten public offering. The Company’s Series B Preferred Stock is entitled to receive a dividend at a rate of 7.50% per year on the $25.00 liquidation preference before the Company’s common stock is paid any dividends and is senior to the Company’s common stock with respect to distributions upon liquidation, dissolution or winding up. Dividends on the Series B Preferred Stock are payable quarterly in arrears on or about March 31, June 30, September 30 and December 31 of each year. The Series B Preferred Stock is redeemable at $25.00 per share plus accrued and unpaid dividends (whether or not authorized or declared), exclusively at the Company’s option. The Series B Preferred Stock generally does not have any voting rights, subject to an exception in the event the Company fails to pay dividends on such stock for six or more quarterly periods (whether or not consecutive). Under such circumstances, the Series B Preferred Stock will be entitled to vote to elect two additional directors to the Company’s Board of Directors (the “Board”), until all unpaid dividends have been paid or declared and set apart for payment. In addition, certain material and adverse changes to the terms of the Series B Preferred Stock cannot be made without the affirmative vote of holders of at least 66 2/3% of the outstanding shares of Series B Preferred Stock. The following table presents cash dividends declared by the Company on its Series B Preferred Stock from January 1, 2022 through June 30, 2023: Declaration Date Record Date Payment Date Dividend Per Share May 22, 2023 June 5, 2023 June 30, 2023 $0.46875 February 21, 2023 March 6, 2023 March 31, 2023 $0.46875 6.50% Series C Fixed-to-Floating Rate Cumulative Redeemable Preferred Stock (“Series C Preferred Stock”) On February 28, 2020, the Company amended its charter through the filing of articles supplementary to reclassify 12,650,000 shares of the Company’s authorized but unissued common stock as shares of the Company’s Series C Preferred Stock. On March 2, 2020, the Company completed the issuance of 11.0 million shares of its Series C Preferred Stock with a par value of $0.01 per share, and a liquidation preference of $25.00 per share plus accrued and unpaid dividends, in an underwritten public offering. The total net proceeds the Company received from the offering were approximately $266.0 million, after deducting offering expenses and the underwriting discount. The Company’s Series C Preferred Stock is entitled to receive dividends (i) from and including the original issue date to, but excluding, March 31, 2025, at a fixed rate of 6.50% per year on the $25.00 liquidation preference and (ii) from and including March 31, 2025, at a floating rate equal to three-month LIBOR plus a spread of 5.345% per year of the $25.00 per share liquidation preference before the Company’s common stock is paid any dividends, and is senior to the Company’s common stock with respect to distributions upon liquidation, dissolution or winding up. In light of the discontinuance of the publication of three-month LIBOR after June 2023 and pursuant to the terms of the Series C Preferred Stock, the Company will, prior to March 31, 2025, appoint a calculation agent to select an industry accepted substitute or successor base rate to the three-month LIBOR rate. The calculation agent may also implement changes to the business day convention, the definition of business day, the dividend determination date, the interest rate spread and the method for obtaining the substitute or successor base rate, in a manner that is consistent with industry accepted practices. In March 2022, Congress enacted a federal statute that provides a safe harbor for those, like the calculation agent, that are contractually responsible for determining LIBOR replacements under certain circumstances, which the Company expects will apply to the Series C Preferred Stock. The Federal Reserve is required to promulgate rules under this statute which, once final, the Company expects will affect the selection of an industry accepted substitute or successor base rate under the terms of the Series C Preferred Stock. Although the Company has not yet appointed a calculation agent and a substitute or successor base rate has not yet been selected, it is the Company’s present expectation that three-month SOFR (Secured Overnight Financing Rate) would be the substitute or successor base rate to three-month LIBOR. Dividends on the Series C Preferred Stock are payable quarterly in arrears on or about March 31, June 30, September 30 and December 31 of each year. The Series C Preferred Stock is not redeemable by the Company prior to March 31, 2025, except under circumstances where it is necessary to preserve the Company’s qualification as a REIT for U.S. federal income tax purposes and upon the occurrence of certain specified change in control transactions. On or after March 31, 2025, the Company may, at its option, subject to certain procedural requirements, redeem any or all of the shares of the Series C Preferred Stock for cash at a redemption price of $25.00 per share, plus any accrued and unpaid dividends thereon (whether or not authorized or declared) to, but excluding, the redemption date. The Series C Preferred Stock generally does not have any voting rights, subject to an exception in the event the Company fails to pay dividends on such stock for six or more quarterly periods (whether or not consecutive). Under such circumstances, the Series C Preferred Stock will be entitled to vote to elect two additional directors to the Company’s Board, until all unpaid dividends have been paid or declared and set apart for payment. In addition, certain material and adverse changes to the terms of the Series C Preferred Stock cannot be made without the affirmative vote of holders of at least 66 2/3% of the outstanding shares of Series C Preferred Stock. The following table presents cash dividends declared by the Company on its Series C Preferred Stock from January 1, 2022 through June 30, 2023: Declaration Date Record Date Payment Date Dividend Per Share May 22, 2023 June 5, 2023 June 30, 2023 $0.40625 February 21, 2023 March 6, 2023 March 31, 2023 0.40625 (b) Dividends on Common Stock The following table presents cash dividends declared by the Company on its common stock from January 1, 2022 through June 30, 2023: Declaration Date Record Date Payment Date Dividend Per Share June 15, 2023 June 30, 2023 July 31, 2023 $0.350 (1) March 10, 2023 March 31, 2023 April 28, 2023 0.350 (1) At June 30, 2023, the Company had accrued dividends and dividend equivalents payable of $35.8 million related to the common stock dividend declared on June 15, 2023. (c) Discount Waiver, Direct Stock Purchase and Dividend Reinvestment Plan (“DRSPP”) On September 27, 2022, the Company filed a shelf registration statement on Form S-3 with the SEC under the Securities Act of 1933, as amended (the “Securities Act”), for the purpose of registering common stock for sale through its DRSPP. Pursuant to Rule 462(e) under the Securities Act, this shelf registration statement became effective automatically upon filing with the SEC and registered an aggregate of 2.0 million shares of common stock. The Company’s DRSPP is designed to provide existing stockholders and new investors with a convenient and economical way to purchase shares of common stock through the automatic reinvestment of dividends and/or optional cash investments. At June 30, 2023, approximately 2.0 million shares of common stock remained available for issuance pursuant to the DRSPP shelf registration statement. During the three and six months ended June 30, 2023, the Company issued 3,440 and 6,666 shares of common stock through the DRSPP, raising net proceeds of approximately $37,000 and $74,000, respectively. From the inception of the DRSPP in September 2003 through June 30, 2023, the Company issued 8,848,219 shares pursuant to the DRSPP, raising net proceeds of $290.8 million. (d) Stock Repurchase Program On March 11, 2022, the Company’s Board authorized a stock repurchase program under which the Company may repurchase up to $250 million of its common stock through the end of 2023. The Board’s authorization superseded and replaced the authorization under a prior stock repurchase program that had been adopted in November 2020, which also authorized the Company to repurchase up to $250 million. The stock repurchase program does not require the purchase of any minimum number of shares. The timing and extent to which the Company repurchases its shares will depend upon, among other things, market conditions, share price, liquidity, regulatory requirements and other factors, and repurchases may be commenced or suspended at any time without prior notice. Acquisitions under the stock repurchase program may be made in the open market, through privately negotiated transactions or block trades or other means, in accordance with applicable securities laws (including, in the Company’s discretion, through the use of one or more plans adopted under Rule 10b5-1 promulgated under the Exchange Act of 1934, as amended (the “Exchange Act”)). The Company did not repurchase any shares of its common stock during the six months ended June 30, 2023. During the three and six months ended June 30, 2022, the Company repurchased 3,280,977 and 6,476,746 shares of its common stock through the stock repurchase program at an average cost of $14.48 and $15.80 per share and a total cost of approximately $47.5 million and $102.1 million, net of fees and commissions paid to the sales agent of approximately $33,000 and $161,000, respectively. As of June 30, 2023, approximately $202.5 million remained available under the current authorization for the purchase of common stock under the stock repurchase program.

Equity Compensation and Other Benefit Plans	Equity Compensation and Other Benefit Plans (a) Equity Compensation Plan In accordance with the terms of the Company’s Equity Plan, which was adopted by the Company’s stockholders on June 6, 2023 (and which amended and restated the Company’s 2020 Equity Compensation Plan), directors, officers and employees of the Company and any of its subsidiaries and other persons expected to provide significant services for the Company and any of its subsidiaries are eligible to receive grants of stock options (“Options”), restricted stock, RSUs, dividend equivalent rights and other stock-based awards under the Equity Plan. Subject to certain exceptions, stock-based awards relating to a maximum of 8.5 million shares of common stock may be granted under the Equity Plan; forfeitures and/or awards that expire unexercised do not count toward this limit. At June 30, 2023, approximately 5.2 million shares of common stock remained available for grant in connection with stock-based awards under the Equity Plan. A participant may generally not receive stock-based awards in excess of 2.0 million shares of common stock in any one year and no award may be granted to any person who, assuming exercise of all Options and payment of all awards held by such person, would own or be deemed to own more than 9.8% of the outstanding shares of the Company’s common stock. Unless previously terminated by the Board, awards may be granted under the Equity Plan until June 6, 2033. Restricted Stock Units Under the terms of the Equity Plan, RSUs are instruments that provide the holder with the right to receive, subject to the satisfaction of conditions set by the Compensation Committee at the time of grant, a payment of a specified value, which may be a share of the Company’s common stock, the fair market value of a share of the Company’s common stock, or such fair market value to the extent in excess of an established base value, on the applicable settlement date. Although the Equity Plan permits the Company to issue RSUs that can settle in cash, all of the Company’s outstanding RSUs as of June 30, 2023 are designated to be settled in shares of the Company’s common stock. The Company granted 90,388 and 1,608,063 RSUs during the three and six months ended June 30, 2023 and granted 74,251 and 677,776 RSUs during the three and six months ended June 30, 2022, respectively. There were 27,413 RSUs forfeited during the three and six months ended June 30, 2023 and 29,693 RSUs forfeited during the three and six months ended June 30, 2022. All holders of RSUs outstanding at June 30, 2023 may be entitled to receive dividend equivalent payments depending on the terms and conditions of the award either in cash at the time dividends are paid by the Company or at the time settlement of the RSU award, or for performance-based RSU awards, as a grant of stock at the time such awards are settled. At June 30, 2023 and December 31, 2022, the Company had unrecognized compensation expense of $18.1 million and $11.2 million, respectively, related to RSUs. The unrecognized compensation expense at June 30, 2023, is expected to be recognized over a weighted average period of 2.0 years. Restricted Stock The Company did not grant any shares of restricted common stock during the six months ended June 30, 2023 and 2022. At June 30, 2023, the Company did not have any shares of restricted common stock outstanding. Dividend Equivalents A dividend equivalent is a right to receive a distribution equal to the dividend distributions that would be paid on a share of the Company’s common stock. Dividend equivalents may be granted as a separate instrument or may be a right associated with the grant of another award (e.g., an RSU) under the Equity Plan, and they are paid typically in cash or other consideration at such times and in accordance with such rules as the Compensation Committee of the Board shall determine in its discretion. Dividend equivalent payments are generally charged to Stockholders’ Equity when common stock dividends are declared to the extent that such equivalents are expected to vest. The Company made dividend equivalent payments associated with RSU awards of approximately $119,000 and $206,000 during the three and six months ended June 30, 2023, respectively, and approximately $141,000 and $311,000 during the three and six months ended June 30, 2022, respectively. In addition, no dividend equivalents rights awarded as separate instruments were granted during the six months ended June 30, 2023 and 2022. Expense Recognized for Equity-Based Compensation Instruments The following table presents the Company’s expenses related to its equity-based compensation instruments for the three and six months ended June 30, 2023 and 2022: Three Months Ended Six Months Ended (In Thousands) 2023 2022 2023 2022 RSUs $ 3,932 $ 3,540 $ 6,952 $ 6,185 Total $ 3,932 $ 3,540 $ 6,952 $ 6,185 (b) Deferred Compensation Plans The Company administers deferred compensation plans for its senior officers and non-employee directors (collectively, the “Deferred Plans”), pursuant to which participants may elect to defer up to 100% of certain cash compensation. The Deferred Plans are designed to align participants’ interests with those of the Company’s stockholders. Amounts deferred under the Deferred Plans are considered to be converted into “stock units” of the Company. Stock units do not represent stock of the Company, but rather are a liability of the Company that changes in value as would equivalent shares of the Company’s common stock. Deferred compensation liabilities are settled in cash at the termination of the deferral period, based on the value of the stock units at that time. The Deferred Plans are non-qualified plans under the Employee Retirement Income Security Act of 1974 and, as such, are not funded. Prior to the time that the deferred accounts are settled, participants are unsecured creditors of the Company. The Company’s liability for stock units in the Deferred Plans is based on the market price of the Company’s common stock at the measurement date. The following table presents the Company’s expenses related to its Deferred Plans for the three and six months ended June 30, 2023 and 2022: Three Months Ended Six Months Ended (In Thousands) 2023 2022 2023 2022 Non-employee directors $ 305 $ (839) $ 414 $ (1,117) Total $ 305 $ (839) $ 414 $ (1,117) The following table presents the aggregate amount of income deferred by participants of the Deferred Plans through June 30, 2023 and December 31, 2022 that had not been distributed and the Company’s associated liability for such deferrals at June 30, 2023 and December 31, 2022: June 30, 2023 December 31, 2022 (In Thousands) Undistributed Income Deferred (1) Liability Under Deferred Plans Undistributed Income Deferred (1) Liability Under Deferred Plans Non-employee directors $ 2,491 $ 2,112 $ 2,923 $ 1,953 Total $ 2,491 $ 2,112 $ 2,923 $ 1,953 (1) Represents the cumulative amounts that were deferred by participants through June 30, 2023 and December 31, 2022, which had not been distributed through such respective date.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments GAAP requires the categorization of fair value measurements into three broad levels that form a hierarchy. 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 on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy. Residential Whole Loans, at Fair Value The Company determines the fair value of its residential whole loans held at fair value after considering valuations obtained from third parties that specialize in providing valuations of residential mortgage loans. The valuation approach applied generally depends on whether the loan is considered performing or non-performing at the date the valuation is performed. For performing loans, estimates of fair value are derived using a discounted cash flow approach, where estimates of cash flows are determined from the scheduled payments, adjusted using forecasted prepayment, default and loss given default rates. For non-performing loans, asset liquidation cash flows are derived based on the estimated time to liquidate the loan, the estimated value of the collateral, expected costs and estimated home price levels. 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’s residential whole loans held at fair value are classified as Level 3 in the fair value hierarchy; however, the Company determined that the market inputs used in valuing its Agency eligible investor loans were sufficiently observable to be classified as Level 2. Securities, at Fair Value Residential Mortgage Securities In determining the fair value of the Company’s residential mortgage securities, management considers a number of observable market data points, including prices obtained from pricing services and brokers as well as dialogue with market participants. Valuations of TBA securities positions are based on executed levels for positions entered into and subsequently rolled forward, as well as prices obtained from pricing services for outstanding positions at each reporting date. These valuations are assessed for reasonableness by considering market TBA levels observed via Bloomberg for the same coupon and term to maturity. In valuing Non-Agency MBS, the Company understands that pricing services use observable inputs that include, in addition to trading activity observed in the marketplace, loan delinquency data, credit enhancement levels and vintage, which are taken into account to assign pricing factors such as spread and prepayment assumptions. The Company collects and considers current market intelligence on all major markets, including benchmark security evaluations and bid-lists from various sources, when available. The Company’s residential mortgage securities are valued using various market data points as described above, which management considers directly or indirectly observable parameters. Accordingly, these securities are classified as Level 2 in the fair value hierarchy. Term Notes Backed by MSR Collateral The Company’s valuation process for term notes backed by MSR collateral is similar to that used for residential mortgage securities and considers a number of observable market data points, including prices obtained from pricing services, brokers and repurchase agreement counterparties, dialogue with market participants, as well as management’s observations of market activity. Other factors taken into consideration include estimated changes in fair value of the related underlying MSR collateral and, as applicable, the financial performance of the ultimate parent or sponsoring entity of the issuer, which has provided a guarantee that is intended to provide for payment of interest and principal to the holders of the term notes should cash flows generated by the related underlying MSR collateral be insufficient. Based on its evaluation of the observability of the data used in its fair value estimation process, these assets are classified as Level 2 in the fair value hierarchy. Financing Agreements, at Fair Value Agreements with mark-to-market collateral provisions These agreements are secured and subject to margin calls and their base interest rates reset frequently to market based rates. As a result, no credit valuation adjustment is required, and the primary factor in determining their fair value is the credit spread paid over the base rate, which is a non-observable input as it is determined based on negotiations with the counterparty. The Company’s financing agreements with mark-to-market collateral provisions held at fair value are classified as Level 2 in the fair value hierarchy if the credit spreads used to price the instrument reset frequently, which is typically the case with shorter term repurchase agreement contracts collateralized by securities. Financing agreements with mark-to-market collateral provisions that are typically longer term and are collateralized by residential whole loans where the credit spread paid over the base rate on the instrument is not reset frequently are classified as Level 3 in the fair value hierarchy. Agreements with non-mark-to-market collateral provisions These agreements are secured, but not subject to margin calls, and their base interest rates reset frequently to market based rates. As a result, a credit valuation adjustment would only be required if there were a significant decrease in collateral value, and the primary factor in determining their fair value is the credit spread paid over the base rate, which is a non-observable input as it is determined based on negotiations with the counterparty. The Company’s financing agreements with non-mark-to-market collateral provisions held at fair value are classified as Level 3 in the fair value hierarchy. Securitized Debt In determining the fair value of securitized debt, management considers a number of observable market data points, including prices obtained from pricing services and brokers as well as dialogue with market participants. Accordingly, the Company’s securitized debt is classified as Level 2 in the fair value hierarchy. Swaps Variation margin payments on the Company’s Swaps are treated as a legal settlement of the exposure under the related Swap contract, the effect of which reduces what would have otherwise been reported as the fair value of the Swap, generally to zero. Changes to the valuation methodologies used with respect to the Company’s financial instruments are reviewed by management to ensure any such changes result in appropriate exit price valuations. The Company will refine its valuation methodologies as markets and products develop and pricing methodologies evolve. The methods described above may produce fair value estimates 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 those used by 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 the measurement date, which may include periods of market dislocation, during which price transparency may be reduced. The Company reviews the classification of its financial instruments within the fair value hierarchy on a quarterly basis, and management may conclude that its financial instruments should be reclassified to a different level in the future. The following tables present the Company’s financial instruments carried at fair value on a recurring basis as of June 30, 2023 and December 31, 2022, on the consolidated balance sheets by the valuation hierarchy, as previously described: Fair Value at June 30, 2023 (In Thousands) Level 1 Level 2 Level 3 Total Assets: Residential whole loans, at fair value $ — $ 58,068 $ 6,441,964 $ 6,500,032 Securities, at fair value — 594,294 — 594,294 Total assets carried at fair value $ — $ 652,362 $ 6,441,964 $ 7,094,326 Liabilities: Agreements with non-mark-to-market collateral provisions $ — $ — $ 440,106 $ 440,106 Agreements with mark-to-market collateral provisions — — 553,162 553,162 Securitized debt — 3,123,478 — 3,123,478 Total liabilities carried at fair value $ — $ 3,123,478 $ 993,268 $ 4,116,746 Fair Value at December 31, 2022 (In Thousands) Level 1 Level 2 Level 3 Total Assets: Residential whole loans, at fair value $ — $ 51,094 $ 5,676,430 $ 5,727,524 Securities, at fair value — 333,364 — 333,364 Total assets carried at fair value $ — $ 384,458 $ 5,676,430 $ 6,060,888 Liabilities: Agreements with non-mark-to-market collateral provisions $ — $ — $ 578,879 $ 578,879 Agreements with mark-to-market collateral provisions — — 884,495 884,495 Securitized debt — 2,435,370 — 2,435,370 Total liabilities carried at fair value $ — $ 2,435,370 $ 1,463,374 $ 3,898,744 Changes in Level 3 Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents additional information for the three and six months ended June 30, 2023 and 2022 about the Company’s Residential whole loans, at fair value, which are classified as Level 3 and measured at fair value on a recurring basis: Residential Whole Loans, at Fair Value Three Months Ended June 30, Six Months Ended June 30, (In Thousands) 2023 2022 2023 2022 Balance at beginning of period $ 6,013,378 $ 4,956,772 $ 5,676,430 $ 4,222,584 Purchases and originations (1) 734,748 674,202 1,071,563 1,788,245 Draws 132,914 82,482 251,991 143,822 Changes in fair value recorded in Net gain/(loss) on residential whole loans measured at fair value through earnings (129,797) (158,507) (2,193) (381,919) Repayments (293,792) (280,662) (527,226) (482,747) Loan sales (900) (8,949) (1,477) (10,496) Transfer to REO (14,586) (13,290) (27,123) (27,441) Balance at end of period $ 6,441,965 $ 5,252,048 $ 6,441,965 $ 5,252,048 (1) Excluded from the table above are approximately $28.9 million of Residential whole loans, at fair value for which the Company committed to purchase during the three months ended March 31, 2022, but for which the closing of the purchase transaction occurred during the three months ended June 30, 2022.

(2) Amounts are weighted based on the fair value of the underlying loan. Changes in market conditions, as well as changes in the assumptions or methodology used to determine fair value, could result in a significant increase or decrease in the fair value of residential whole loans. Loans valued using a discounted cash flow model are most sensitive to changes in the discount rate assumption, while loans valued using the liquidation model technique are most sensitive to changes in the current value of the underlying properties and the liquidation timeline. Increases in discount rates, default rates, loss severities, or liquidation timelines, either in isolation or collectively, would generally result in a lower fair value measurement, whereas increases in the current or expected value of the underlying properties, in isolation, would result in a higher fair value measurement. In practice, changes in valuation assumptions may not occur in isolation and the changes in any particular assumption may result in changes in other assumptions, which could offset or amplify the impact on the overall valuation. The following table presents the carrying values and estimated fair values of the Company’s financial instruments at June 30, 2023 and December 31, 2022: June 30, 2023 June 30, 2023 December 31, 2022 Level in Fair Value Hierarchy Carrying Estimated Fair Value Carrying Estimated Fair Value (In Thousands) Financial Assets: Residential whole loans 3 $ 8,081,718 $ 8,023,447 $ 7,467,645 $ 7,397,421 Residential whole loans 2 58,068 58,068 51,094 51,094 Securities, at fair value 2 594,294 594,294 333,364 333,364 Cash and cash equivalents 1 329,391 329,391 334,183 334,183 Restricted cash 1 174,005 174,005 159,898 159,898 Financial Liabilities (1) : Financing agreements with non-mark-to-market collateral provisions 3 967,884 968,546 1,003,604 1,004,260 Financing agreements with mark-to-market collateral provisions 3 1,938,379 1,939,310 2,111,396 2,111,647 Financing agreements with mark-to-market collateral provisions 2 464,064 464,064 111,651 111,651 Securitized debt (2) 2 3,969,274 3,839,491 3,357,590 3,217,905 Convertible senior notes 2 228,575 220,071 227,845 211,015 (1) Carrying value of securitized debt, Convertible Senior Notes, Senior Notes and certain repurchase agreements is net of associated debt issuance costs.

Use of Special Purpose Entities and Variable Interest Entities
Use of Special Purpose Entities and Variable Interest Entities	Use of Special Purpose Entities and Variable Interest Entities A Special Purpose Entity (“SPE”) is an entity designed to fulfill a specific limited need of the company that organized it. SPEs are often used to facilitate transactions that involve securitizing financial assets or re-securitizing previously securitized financial assets. The objective of such transactions may include obtaining non-recourse financing, obtaining liquidity or refinancing the underlying financial assets on improved terms. Securitization involves transferring assets to a SPE to convert all or a portion of those assets into cash before they would have been realized in the normal course of business, through the SPE’s issuance of debt or equity instruments. Investors in a SPE usually have recourse only to the assets in the SPE and, depending on the overall structure of the transaction, may benefit from various forms of credit enhancement such as over-collateralization in the form of excess assets in the SPE, priority with respect to receipt of cash flows relative to holders of other debt or equity instruments issued by the SPE, or a line of credit or other form of liquidity agreement that is designed with the objective of ensuring that investors receive principal and/or interest cash flow on the investment in accordance with the terms of their investment agreement. The Company has entered into several financing transactions that resulted in the Company consolidating as VIEs the SPEs that were created to facilitate these transactions. See Note 2(p) for a discussion of the accounting policies applied to the consolidation of VIEs and transfers of financial assets in connection with financing transactions. The Company has engaged in loan securitizations primarily for the purpose of obtaining improved overall financing terms as well as non-recourse financing on a portion of its residential whole loan portfolio. Notwithstanding the Company’s participation in these transactions, the risks facing the Company are largely unchanged as the Company remains economically exposed to the first loss position on the underlying assets transferred to the VIEs. Loan Securitization Transactions The following table summarizes the key details of the Company’s consolidated loan securitization transactions currently outstanding as of June 30, 2023 and December 31, 2022: (Dollars in Thousands) June 30, 2023 December 31, 2022 Aggregate unpaid principal balance of residential whole loans sold $ 7,119,527 $ 6,079,749 Face amount of Senior Bonds issued by the VIE and purchased by third-party investors $ 6,165,095 $ 5,333,090 Outstanding amount of Senior Bonds, at carrying value $ 845,796 (1) $ 922,220 (1) Outstanding amount of Senior Bonds, at fair value $ 3,123,478 $ 2,435,370 Outstanding amount of Senior Bonds, total $ 3,969,274 $ 3,357,590 Weighted average fixed rate for Senior Bonds issued 3.85 % (2) 3.38 % (2) Weighted average contractual maturity of Senior Bonds 37 years (2) 38 years (2) Face amount of Senior Support Certificates received by the Company (3) $ 919,974 $ 715,640 Cash received $ 6,103,771 $ 5,286,305 (1) Net of $2.0 million and $2.9 million of deferred financing costs at June 30, 2023 and December 31, 2022, respectively. (2) At June 30, 2023 and December 31, 2022, $2.6 billion and $1.9 million, respectively, of Senior Bonds sold in securitization transactions contained a contractual coupon step-up feature whereby the coupon increases by either 100, 200, or 300 basis points or more at defined dates ranging from 24 months, up to 48 months from issuance if the bond is not redeemed before such date. (3) Provides credit support to the Senior Bonds sold to third-party investors in the securitization transactions. During the three and six months ended June 30, 2023, the Company issued Senior Bonds with a current face of $308.8 million and $832.0 million to third-party investors for proceeds of $296.4 million and $817.5 million, respectively, before offering costs and accrued interest. The Senior Bonds issued by the Company during the three months ended June 30, 2023 are included in “Financing agreements, at fair value” (at carrying value) on the Company’s consolidated balance sheets (see Note 6). As of June 30, 2023 and December 31, 2022, as a result of the transactions described above, securitized loans of approximately $4.8 billion and $4.0 billion are included in “Residential whole loans” and REO with a carrying value of approximately $30.4 million and $36.5 million are included in “Other assets” on the Company’s consolidated balance sheets, respectively. As of June 30, 2023 and December 31, 2022, the aggregate carrying value of Senior Bonds issued by consolidated VIEs was $4.0 billion and $3.4 billion, respectively. These Senior Bonds are disclosed as “Securitized debt” and are included in Financing agreements on the Company’s consolidated balance sheets. The holders of the securitized debt have no recourse to the general credit of the Company, but the Company does have the obligation, under certain circumstances, to repurchase assets from the VIE upon the breach of certain representations and warranties with respect to the residential whole loans sold to the VIE. In the absence of such a breach, the Company has no obligation to provide any other explicit or implicit support to any VIE. The Company concluded that the entities created to facilitate the loan securitization transactions are VIEs. The Company completed an analysis of whether each VIE created to facilitate the securitization transactions should be consolidated by the Company, based on consideration of its involvement in each VIE, including the design and purpose of the SPE, and whether its involvement reflected a controlling financial interest that resulted in the Company being deemed the primary beneficiary of each VIE. In determining whether the Company would be considered the primary beneficiary, the following factors were assessed: • whether the Company has both the power to direct the activities that most significantly impact the economic performance of the VIE; and • whether the Company has a right to receive benefits or absorb losses of the entity that could be potentially significant to the VIE. Based on its evaluation of the factors discussed above, including its involvement in the purpose and design of the entity, the Company determined that it was required to consolidate each VIE created to facilitate the loan securitization transactions.

The Lima One segment includes the stand-alone mortgage origination and servicing business of Lima One, including related goodwill, intangible assets, and direct expenses, plus Lima One-related residential whole loans and REO (defined as both those owned by Lima One on the acquisition date and those originated by Lima One since the acquisition date) and the economics related thereto (including any related taxes and the economics of associated financing and hedging instruments), all as recorded under GAAP. Associated financing economics are equal to the results of direct financings of Lima One-related residential whole loans and REO plus allocations of the results of financings which include Lima One related residential whole loans and REO as part of their collateral, based on the relative carrying values of the financed assets. Associated hedging economics are equal to allocations of the Company’s overall hedging results based on the relative estimated duration of each asset class hedged and the relative fair values of assets within each asset class.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation On April 4, 2022, the Company effected a one-for-four reverse stock split of its issued and outstanding shares of common stock (the “Reverse Stock Split”). Accordingly, all share and per share data included in these consolidated financial statements and notes thereto have been adjusted retroactively to reflect the impact of the Reverse Stock Split. The interim unaudited consolidated financial statements of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted in accordance with these SEC rules and regulations. Management believes that the disclosures included in these interim unaudited consolidated financial statements are adequate to make the information presented not misleading. The accompanying unaudited consolidated financial statements should 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, 2022. In the opinion of management, all normal and recurring adjustments necessary to present fairly the financial condition of the Company at June 30, 2023 and results of operations for all periods presented have been made. The results of operations for the three and six months ended June 30, 2023 should not be construed as indicative of the results to be expected for the full year. The accompanying consolidated financial statements of the Company 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. 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 differ from those estimates, which could materially impact the Company’s results of operations and its financial condition. Management has made significant estimates in several areas: impairment, valuation allowances and loss allowances on residential whole loans (see Note 3), certain securities designated as available-for- sale (“AFS”) (see Note 4) and certain Other assets (see Note 5), valuation of Securities, at fair value (see Notes 4 and 13), income recognition and valuation of residential whole loans (see Notes 3 and 13), valuation of financing agreements (Notes 6 and 13), and valuation of derivative instruments (see Notes 5(d) and 13). In addition, estimates are used in the determination of taxable income used in the assessment of REIT compliance and contingent liabilities for related taxes, penalties and interest (see Note 8). Actual results could differ from those estimates. The consolidated financial statements of the Company include the accounts of all subsidiaries. All intercompany accounts and transactions have been eliminated. In addition, the Company consolidates entities established to facilitate transactions related to the acquisition and securitization of residential whole loans. Certain prior period amounts have been reclassified to conform to the current period presentation.
Residential Whole Loans (including Residential Whole Loans transferred to consolidated VIEs)	Residential Whole Loans (including Residential Whole Loans transferred to consolidated VIEs) Residential whole loans included in the Company’s consolidated balance sheets are primarily comprised of pools of fixed- and adjustable-rate residential mortgage loans acquired through consolidated trusts in secondary market transactions or originated by Lima One. The accounting model utilized by the Company is determined at the time each loan package is initially acquired. Prior to the second quarter of 2021, the Company typically elected the fair value option on loans that were 60 or more days delinquent at purchase (“Purchased Non-performing Loans”). Purchased Credit Deteriorated Loans (i.e., mortgage loans in which the underlying borrower had a delinquency status of less than 60 days at the acquisition date) acquired prior to the second quarter of 2021 are typically held at carrying value. Purchased Performing Loans (as described below) acquired prior to the second quarter of 2021 are also typically held at carrying value, but the accounting methods for income recognition and determination and measurement of any required credit loss reserves (as discussed below) differ from those used for Purchased Credit Deteriorated Loans held at carrying value. Starting in the second quarter of 2021, the Company began to elect the fair value option for all loans acquired, irrespective of borrower delinquency status at acquisition. The accounting model initially applied to loan acquisitions is not permitted to be subsequently changed. Consequently, the Company is not permitted to retroactively apply fair value accounting to loans held at carrying value acquired in periods prior to the second quarter of 2021. The Company’s residential whole loans pledged as collateral against financing agreements are included in the consolidated balance sheets with amounts pledged disclosed in Note 6. Purchases and sales of residential whole loans that are subject to an extended period of due diligence that crosses a reporting date are recorded in the Company’s balance sheet at amounts reflecting management’s current estimate of assets that will be acquired or disposed at the closing of the transaction. This estimate is subject to revision at the closing of the transaction, pending the outcome of due diligence performed prior to closing. Residential whole loans purchased under flow arrangements with loan origination partners are generally recorded at the transaction settlement date. Recorded amounts of residential whole loans for which the closing of the purchase transaction is yet to occur are not eligible to be pledged as collateral against any financing agreement until the closing of the purchase transaction. Interest income, credit related losses and changes in the fair value of loans held at fair value are recorded post settlement for acquired loans and until transaction settlement for sold loans (see Notes 3, 6, 13 and 14). Purchased Performing Loans Acquisitions of Purchased Performing Loans to date (which include loans purchased from third parties or loans originated by Lima One) have been primarily comprised of: (i) loans to finance (or refinance) one-to-four family residential properties that are not considered to meet the definition of a “Qualified Mortgage” in accordance with guidelines adopted by the Consumer Financial Protection Bureau (“Non-QM loans”), (ii) short-term business purpose loans collateralized by residential and multi-family properties made to non-occupant borrowers that intend to rehabilitate and sell the properties (“Transitional loans” or “TL”) (also sometimes referred to as “Rehabilitation loans” or “Fix and Flip loans”), (iii) business purpose loans to finance (or refinance) non-owner occupied one-to-four family residential properties that are rented to one or more tenants (“Single-family rental loans”), (iv) loans on investor properties that conform to the standards for purchase by a federally chartered corporation, such as the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”) (“Agency eligible investor loans”), and (v) previously originated loans secured by residential real estate that is generally owner occupied (“Seasoned performing loans”). Purchased Performing Loans are initially recorded at their purchase price (or amount funded for originated loans). Interest income on Purchased Performing Loans acquired at par is accrued based on each loan’s current interest bearing balance and current interest rate. Interest income on such loans acquired at a premium/discount to par is recorded each period based on the contractual coupon net of any amortization of premium or accretion of discount, adjusted for actual prepayment activity. For loans acquired with related servicing rights retained by the seller, interest income is reported net of related serving costs. For Purchased Performing Loans acquired prior to the second quarter of 2021 for which the fair value option was not elected, an allowance for credit losses is recorded at acquisition, and maintained on an ongoing basis, for all losses expected over the life of the respective loan. Any required credit loss allowance would reduce the net carrying value of the loan with a corresponding charge to earnings, and may increase or decrease over time. Significant judgments are required in determining any allowance for credit loss, including assumptions regarding the loan cash flows expected to be collected, the value of the underlying collateral and the ability of the Company to collect on any other forms of security, such as a personal guaranty provided either by the borrower or an affiliate of the borrower. Income recognition is suspended, and interest accruals are reversed against income, for loans at the earlier of the date on which payments become 90 days past due or when, in the opinion of management, a full recovery of income and principal becomes doubtful (i.e., such loans are placed on nonaccrual status). For nonaccrual loans, interest income is recorded under the cash basis method as interest payments are received. Interest accruals are resumed when the loan becomes contractually current. A loan is written off when it is no longer realizable and/or it is legally discharged. Modified loans are considered “troubled debt restructurings” if the Company grants a concession to a borrower who is experiencing financial difficulty (including the interpretation of this definition set forth in OCC Bulletin 2020-35). Charge-offs to the allowance for loan losses occur when losses are confirmed through the receipt of cash or other consideration from the completion of a sale; when a modification or restructuring takes place in which we grant a concession to a borrower or agree to a discount in full or partial satisfaction of the loan; when we take ownership and control of the underlying collateral in full satisfaction of the loan; when loans are reclassified as other investments; or when significant collection efforts have ceased and it is highly likely that a loss has been realized. The aggregate allowance for credit losses is equal to the sum of the losses expected over the life of each respective loan. Expected losses are generally calculated based on the estimated probability of default and loss severity of loans in the portfolio, which involves projecting each loan’s expected cash flows based on their contractual terms, expected prepayments, and estimated default and loss severity rates. The results were not discounted. The default and severity rates were estimated based on the following steps: (i) obtained the Company’s historical experience through an entire economic cycle for each loan type or, to the extent the Company did not have sufficient historical loss experience for a given loan type, publicly available data derived from the historical loss experience of certain banks, which data the Company believes is generally representative of its portfolio, (ii) obtained historical economic data (U.S. unemployment rates and home price appreciation) over the same period, and (iii) estimated default and severity rates during three distinct future periods based on historical default and severity rates during periods when economic conditions similar to those forecasted were experienced. The default and severity rates were applied to the estimated amount of loans outstanding during each future period, based on contractual terms and expected prepayments. Expected prepayments are estimated based on historical experience and current and expected future economic conditions, including market interest rates. The three periods were as follows: (i) a one-year forecast of economic conditions based on U.S. unemployment rates and home price appreciation, followed by (ii) a two-year “reversion” period during which economic conditions (U.S. unemployment rates and home price appreciation) are projected to revert to historical averages on a straight line basis, followed by (iii) the remaining life of each loan, during which period economic conditions (U.S. unemployment rates and home price appreciation) are projected to equal historical averages. In addition, a liability is established (and recorded in Other Liabilities) each period using a similar methodology for committed but undrawn loan amounts. The Company forecasts future economic conditions based on forecasts provided by an external preparer of economic forecasts, as well as its own knowledge of the market and its portfolio. The Company may consider multiple scenarios and select the one that it believes results in the most reasonable estimate of expected losses. The Company may apply qualitative adjustments to these results as further described in Note 3. For certain loans where foreclosure has been deemed to be probable, loss estimates are based on whether the value of the underlying collateral is sufficient to recover the carrying value of the loan. This methodology has not changed significantly from the calculation of the allowance for credit losses in prior periods. Purchased Credit Deteriorated Loans The Company has elected to account for these loans as credit deteriorated, as they have experienced a deterioration in credit quality since origination and prior to our purchase and were acquired at discounted prices that reflect, in part, the impaired credit history of the borrower. Substantially all of these loans have previously experienced payment delinquencies and the amount owed may exceed the value of the property pledged as collateral. Consequently, these loans generally have a higher likelihood of default than newly originated mortgage loans with loan-to-value ratios (“LTVs”) of 80% or less to creditworthy borrowers. The Company believes that amounts paid to acquire these loans represent fair market value at the date of acquisition. Loans considered credit deteriorated are initially recorded at their purchase price on a net basis, after establishing an initial allowance for credit losses (their initial cost basis is equal to their purchase price plus the initial allowance for credit losses). Subsequent to acquisition, the gross recorded amount for these loans reflects the initial cost basis, plus accretion of interest income, less principal and interest cash flows received. Purchased Credit Deteriorated Loans acquired prior to the second quarter of 2021, or where the fair value option was not otherwise elected, are presented on the Company’s consolidated balance sheets at carrying value, which reflects the recorded cost basis reduced by any allowance for credit losses. Interest income on such loans purchased is recorded each period based on the contractual coupon net of amortization of the difference between their cost basis and unpaid principal balance (“UPB”), subject to the Company’s nonaccrual policy. Residential Whole Loans at Fair Value Certain of the Company’s residential whole loans are presented at fair value on its consolidated balance sheets as a result of a fair value election made at the time of acquisition. Prior to the second quarter of 2021, this accounting election was made primarily on Purchased Non-performing Loans. Starting in the second quarter of 2021, the Company made the fair value election on all loan acquisitions, which, to date, have been comprised exclusively of Purchased Performing Loans (including loans originated by Lima One since its consolidation). The Company generally considers accounting for these loans at fair value to be more reflective of the expected pattern of returns from these loans under current economic conditions. The Company determines the fair value of its residential whole loans held at fair value after considering portfolio valuations obtained from third-parties that specialize in providing valuations of residential mortgage loans and trading activity observed in the marketplace. Subsequent changes in fair value are reported in current period earnings and presented in Net (loss)/gain on residential whole loans measured at fair value through earnings on the Company’s consolidated statements of operations. Interest income is recorded on these loans based on their yield and is presented as part of interest income in the Company’s consolidated statements of operations. Cash outflows associated with loan-related advances made by the Company on behalf of the borrower are included in the basis of the loan and are reflected in unrealized gains or losses reported each period. Income and costs associated with originating loans on which the fair value option was elected are recorded in other income and expense respectively in the period in which they are earned or incurred.
Securities, at Fair Value	Securities, at Fair Value Residential Mortgage Securities The Company has invested in residential MBS that are issued or guaranteed as to principal and/or interest by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government, such as the Government National Mortgage Association (“Ginnie Mae”) (collectively, “Agency MBS”), and residential MBS that are not guaranteed by any agency of the U.S. Government or any federally chartered corporation (“Non-Agency MBS”). In addition, the Company has investments in CRT securities that are issued by or sponsored by Fannie Mae and Freddie Mac. The coupon payments on CRT securities are paid by the issuer and the principal payments received are dependent on the performance of loans in either a reference pool or an actual pool of loans. As the loans in the underlying pool are paid, the principal balance of the CRT securities is paid. As an investor in a CRT security, the Company may incur a principal loss if the performance of the actual or reference pool loans results in either an actual or calculated loss that exceeds the credit enhancement of the security owned by the Company. Term Notes Backed by MSR Collateral The Company has invested in term notes that are issued by special purpose vehicles (“SPV”) that have acquired rights to receive cash flows representing the servicing fees and/or excess servicing spread associated with certain MSRs. The Company considers payment of principal and interest on these term notes to be largely dependent on the cash flows generated by the underlying MSRs as this impacts the cash flows available to the SPV that issued the term notes. Credit risk borne by the holders of the term notes is also mitigated by structural credit support in the form of over-collateralization. Credit support is also provided by a corporate guarantee from the ultimate parent or sponsor of the SPV that is intended to provide for payment of interest and principal to the holders of the term notes should cash flows generated by the underlying MSRs be insufficient. Designation Securities that the Company generally intends to hold until maturity, but that it may sell from time to time as part of the overall management of its business, are designated as AFS. Such securities, which include term notes backed by MSR collateral and certain CRT securities, are carried at their fair value with unrealized gains and losses excluded from earnings (except when an allowance for loan losses is recognized, as discussed below) and reported in accumulated other comprehensive income (“AOCI”), a component of Stockholders’ Equity. Upon the sale of an AFS security, any unrealized gain or loss is reclassified out of AOCI to earnings as a realized gain or loss using the specific identification method. The Company has elected the fair value option for its Agency and Non-Agency MBS and certain of its CRT securities. These securities are carried at their fair value with changes in fair value included in earnings for the period and reported in Other Income, net on the Company’s consolidated statements of operations. Revenue Recognition, Premium Amortization and Discount Accretion Interest income on securities is accrued based on their outstanding principal balance and their contractual terms. Premiums and discounts associated with MBS assessed as high credit quality at the time of purchase are amortized into interest income over the life of such securities using the effective yield method. Adjustments to premium amortization are made for actual prepayment activity. Determination of Fair Value for Securities In determining the fair value of the Company’s securities, management considers a number of observable market data points, including prices obtained from pricing services, brokers and repurchase agreement counterparties, dialogue with market participants, as well as management’s observations of market activity (see Note 13). For term notes backed by MSR collateral, other factors taken into consideration include estimated changes in fair value of the related underlying MSR collateral, as applicable, and the financial performance of the ultimate parent or sponsoring entity of the issuer, which has provided a guarantee that is intended to provide for payment of interest and principal to the holders of the term notes should cash flows generated by the related underlying MSR collateral be insufficient. Allowance for credit losses When the fair value of an AFS security is less than its amortized cost at the balance sheet date, the security is considered impaired. The Company assesses its impaired securities, as well as securities for which a credit loss allowance had been previously recorded, on at least a quarterly basis and determines whether any changes to the allowance for credit losses are required. If the Company intends to sell an impaired security, or it is more likely than not that it will be required to sell the impaired security before its anticipated recovery, then the Company must recognize a write-down through charges to earnings equal to the entire difference between the investment’s amortized cost and its fair value at the balance sheet date. If the Company does not expect to sell an impaired security, only the portion of the impairment related to credit losses is recognized through a loss allowance charged to earnings with the remainder recognized through AOCI on the Company’s consolidated balance sheets. Impairments recognized through other comprehensive income/(loss) (“OCI”) do not impact earnings. Credit loss allowances are subject to reversal through earnings resulting from improvements in expected cash flows. The determination as to whether to record (or reverse) a credit loss allowance is subjective, as such determinations are based on factual information available at the time of assessment as well as the Company’s estimates of future performance and cash flow projections. As a result, the timing and amount of losses constitute material estimates that are susceptible to significant change (see Note 4). Balance Sheet Presentation
Cash and Cash Equivalents	Cash and Cash Equivalents  Cash and cash equivalents include cash on deposit with financial institutions and investments in money market funds, all of which have original maturities of three months or less.  Cash and cash equivalents may also include cash pledged as collateral to the Company by its financing counterparties as a result of reverse margin calls (i.e., margin calls made by the Company).  The Company did not hold any cash pledged by its counterparties at June 30, 2023 and December 31, 2022.
Restricted Cash	Restricted Cash
Goodwill & Intangible Assets	Goodwill & Intangible Assets At June 30, 2023 and December 31, 2022, the Company had goodwill of $61.1 million, which represents the excess of the fair value of consideration paid over the fair value of net assets acquired in connection with the acquisition of Lima One, and other intangible assets of $9.6 million and $12.2 million, respectively (net of amortization), primarily comprised of customer relationships, non-competition agreements (fully amortized as of June 30, 2022), trademarks and trade names, and internally developed software recognized as part of the acquisition of Lima One (see Note 5(b)). The intangible assets are amortized over their expected useful lives, which ranged from one
Real Estate Owned (REO)	Real Estate Owned (“REO”) REO represents real estate acquired by the Company, including through foreclosure, deed in lieu of foreclosure, or purchased in connection with the acquisition of residential whole loans. REO acquired through foreclosure or deed in lieu of foreclosure is initially recorded at fair value less estimated selling costs. REO acquired in connection with the acquisition of residential whole loans is initially recorded at its purchase price. Subsequent to acquisition, REO is reported, at each reporting date, at the lower of the current carrying amount or fair value less estimated selling costs and for presentation purposes is included in Other assets on the Company’s consolidated balance sheets. Changes in fair value that result in an adjustment to the reported amount of an REO property that has a fair value at or below its carrying amount are reported in Other Income, net on the Company’s consolidated statements of operations
Leases	LeasesThe Company records its operating lease liabilities and operating lease right-of-use assets on its consolidated balance sheets. The operating lease liabilities are equal to the present value of the remaining fixed lease payments (excluding real estate tax and operating expense escalations) discounted at the Company’s estimated incremental borrowing rate at the date of lease commencement, and the operating lease right-of-use assets are equal to the operating lease liabilities adjusted for lease incentives and initial direct costs. As lease payments are made, the operating lease liabilities are reduced to the present value of the remaining lease payments and the operating lease right-of-use assets are reduced by the difference between the lease expense (straight-lined over the lease term) and the theoretical interest expense amount (calculated using the incremental borrowing rate at the date of lease commencement).
Leasehold Improvements, Real estate and Other Depreciable Assets	Leasehold Improvements, Real estate and Other Depreciable Assets Depreciation is computed on the straight-line method over the estimated useful life of the related assets or, in the case of leasehold improvements, over the shorter of the useful life or the lease term. Furniture, fixtures, computers and related hardware have estimated useful lives ranging from five
Loan Securitization and Other Debt Issuance Costs	Loan Securitization and Other Debt Issuance Costs Loan securitization related costs are costs associated with the issuance of beneficial interests by consolidated VIEs and incurred by the Company in connection with various financing transactions completed by the Company. These costs may include underwriting, rating agency, legal, accounting and other fees. Such costs, which reflect deferred charges (unless the debt is recorded at fair value, as discussed below), are included on the Company’s consolidated balance sheets as a direct deduction from the corresponding debt liability. These deferred charges are amortized as an adjustment to interest expense using the effective interest method. For certain financing agreements, such costs are amortized over the shorter of the period to the expected or stated legal maturity of the debt instruments. The Company periodically reviews the recoverability of these deferred costs and, in the event an impairment charge is required, such amount will be included in Operating and Other Expense on the Company’s consolidated statements of operations. To the extent that the Company has elected the fair value option for the related debt liability, these costs are expensed at the closing of the transaction.
Financing Arrangements	Financing Agreements The Company finances the majority of its residential mortgage assets with financing agreements that include repurchase agreements and other forms of collateralized financing. Under repurchase agreements, the Company sells assets to a lender and agrees to repurchase the same assets in the future for a price that is higher than the original sale price. The difference between the sale price that the Company receives and the repurchase price that the Company pays represents interest paid to the lender. Although legally structured as sale and repurchase transactions, the Company accounts for repurchase agreements as secured borrowings. Under its repurchase agreements and other forms of collateralized financing, the Company pledges its assets as collateral to secure the borrowing, in an amount which is equal to a specified percentage of the fair value of the pledged collateral, while the Company retains beneficial ownership of the pledged collateral. At the maturity of a repurchase financing, unless the repurchase financing is renewed with the same counterparty, the Company is required to repay the loan including any accrued interest and concurrently receives back its pledged collateral from the lender. With the consent of the lender, the Company may renew a repurchase financing at the then prevailing financing terms. Margin calls, whereby a lender requires that the Company pledge additional assets or cash as collateral to secure borrowings under its repurchase financing with such lender, are routinely experienced by the Company when the value of the assets pledged as collateral declines as a result of principal amortization and prepayments or due to changes in market interest rates, spreads or other market conditions. The Company also may make margin calls on counterparties when collateral values increase. Should a counterparty decide not to renew a financing arrangement at maturity, the Company must either refinance elsewhere or be in a position to satisfy the obligation. If, during the term of a financing, a lender should default on its obligation, the Company might experience difficulty recovering its pledged assets which could result in an unsecured claim against the lender for the difference between the amount loaned to the Company plus interest due to the counterparty and the fair value of the collateral pledged by the Company to such lender, including accrued interest receivable on such collateral (see Notes 6 and 13). The Company has elected the fair value option on certain of its financing agreements. These agreements are reported at their fair value, with changes in fair value being recorded in earnings each period (or other comprehensive income, to the extent the change results from a change in instrument specific credit risk), as further detailed in Note 6. Financing costs, including “up front” fees paid at inception related to financing agreements at fair value are expensed as incurred. Interest expense is recorded based on the current interest rate in effect for the related agreement.
Equity-Based Compensation	Equity-Based Compensation Compensation expense for equity-based awards that are subject to vesting conditions, is recognized ratably over the vesting period of such awards, based upon the fair value of such awards at the grant date. The Company has made annual grants of restricted stock units (“RSUs”) under the Company’s Equity Compensation Plan (the “Equity Plan”), certain of which cliff vest after a three-year period, subject only to continued employment, and others of which cliff vest after a three-year period, subject to both continued employment and the achievement of certain performance criteria based on a formula tied to the Company’s achievement of average total shareholder return (“TSR”) during that three-year period, as well as the TSR of the Company relative to the TSR of a group of peer companies (over the three-year period) selected by the Compensation Committee of the Company’s Board of Directors (the “Compensation Committee”) at the date of grant. The features in these awards related to the attainment of TSR over a specified period constitute a “market condition,”
Earnings per Common Share (EPS)	Earnings per Common Share (“EPS”)  Basic EPS is computed using the two-class method, which includes the weighted-average number of shares of common stock outstanding during the period and an estimate of other securities that participate in dividends, to arrive at total common equivalent shares.  In applying the two-class method, earnings are allocated to both shares of common stock and estimated securities that participate in dividends based on their respective weighted-average shares outstanding for the period.  For the diluted EPS calculation, common equivalent shares are further adjusted for the effect of RSUs outstanding that are unvested and have dividends that are subject to forfeiture, using the treasury stock method.  Under the treasury stock method, common equivalent shares are calculated assuming that all dilutive common stock equivalents are exercised and the proceeds, along with future compensation expenses associated with such instruments (if any), are used to repurchase shares of the Company’s outstanding common stock at the average market price during the reported period.  In addition, the Company’s 6.25% Convertible Senior Notes due 2024 (the “Convertible Senior Notes”) are included in the calculation of diluted EPS if the assumed conversion into common shares is dilutive, using the “if-converted” method. This calculation involves adding back the periodic interest expense associated with the Convertible Senior Notes to the numerator and by adding the shares that would be issued in an assumed conversion (regardless of whether the conversion option is in or out of the money) to the denominator for the purposes of calculating diluted EPS
Comprehensive Income/(Loss)	Comprehensive Income/(Loss) The Company’s comprehensive income/(loss) available to common stock and participating securities includes net income, the change in net unrealized gains/(losses) on its AFS securities and derivative hedging instruments (to the extent that such changes are not recorded in earnings), adjusted by realized net gains/(losses) reclassified out of AOCI for sold AFS securities and terminated hedging relationships, as well as the portion of unrealized gains/(losses) on its financing agreements held at fair value related to instrument-specific credit risk, and is reduced by dividends declared on the Company’s preferred stock and issuance costs of redeemed preferred stock.
Derivative Financial Instruments	Derivative Financial Instruments The Company may use derivative instruments to economically hedge a portion of its exposure to market risks, including interest rate risk and prepayment risk. The objective of the Company’s risk management strategy is to reduce fluctuations in net book value over a range of interest rate scenarios. Swaps The Company has entered into Swaps that are not designated as hedges for accounting purposes. Changes in the fair value of the Company’s Swaps not designated in hedging transactions are recorded in Other income, net on the Company’s consolidated statements of operations (see Note 5(d)). To Be Announced (“TBA”) Securities During 2021 and 2022, the Company entered into transactions to take short positions in TBA securities in connection with the management of interest rate and other market risks associated with purchases of Agency eligible investor loans. As the Company did not intend to physically settle its transactions in TBA securities, they were required to be accounted for as derivative financial instruments. The Company did not apply hedge accounting to its TBA securities. Accordingly, TBA securities were recorded on the Company’s balance sheets at fair value, with realized and unrealized changes in fair value each period recorded in Other income, net in the Company’s consolidated statements of operations.
Fair Value Measurements and the Fair Value Option for Financial Assets and Financial Liabilities	Fair Value Measurements and the Fair Value Option for Financial Assets and Financial Liabilities The Company’s presentation of fair value for its financial assets and liabilities is determined within a framework that stipulates that the fair value of a financial asset or liability is an exchange price in an orderly transaction between market participants to sell the asset or transfer the liability in the market in which the reporting entity would transact for the asset or liability, that is, the principal or most advantageous market for the asset or liability. The transaction to sell the asset or transfer the liability is a hypothetical transaction at the measurement date, considered from the perspective of a market participant that holds the asset or owes the liability. This definition of fair value focuses on exit price and prioritizes the use of market-based inputs over entity-specific inputs when determining fair value. In addition, the framework for measuring fair value establishes a three-level hierarchy for fair value measurements based upon the observability of inputs to the valuation of an asset or liability as of the measurement date.
Variable Interest Entities	Variable Interest Entities An entity is referred to as a VIE if it meets at least one of the following criteria: (i) the entity has equity that is insufficient to permit the entity to finance its activities without the additional subordinated financial support of other parties; or (ii) as a group, the holders of the equity investment at risk lack (a) the power to direct the activities of an entity that most significantly impact the entity’s economic performance; (b) the obligation to absorb the expected losses; or (c) the right to receive the expected residual returns; or (iii) the holders of the equity investment at risk have disproportional voting rights and the entity’s activities are conducted on behalf of the investor that has disproportionately few voting rights. The Company consolidates a VIE when it 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 has entered into several financing transactions which resulted in the Company forming entities to facilitate these transactions. In determining the accounting treatment to be applied to these transactions, the Company concluded that the entities used to facilitate these transactions are VIEs and that they should be consolidated. If the Company had determined that consolidation was not required, it would have then assessed whether the transfers of the underlying assets would qualify as sales or should be accounted for as secured financings under GAAP (see Note 14). The Company also includes on its consolidated balance sheets certain financial assets and liabilities that are acquired/issued by trusts and/or other special purpose entities that have been evaluated as being required to be consolidated by the Company under the applicable accounting guidance.
Offering Costs Related to Issuance and Redemption of Preferred Stock	Offering Costs Related to Issuance and Redemption of Preferred Stock Offering costs related to the issuance of preferred stock are recorded as a reduction in Additional paid-in capital, a component of Stockholders’ Equity, at the time such preferred stock is issued. On redemption of preferred stock, any excess of the fair value of the consideration transferred to the holders of the preferred stock over the carrying amount of the preferred stock in the Company’s consolidated balance sheets is included in the determination of Net Income Available to Common Stock and Participating Securities in the calculation of EPS.
New Accounting Standards and Interpretations	New Accounting Standards and Interpretations As of June 30, 2023, there were no new accounting standards or interpretations adopted by the Company that had a material effect on its consolidated financial statements in 2023.

As of December 31, 2022, Transitional loans includes $632.3 million of loans collateralized by multi-family properties with a weighted average term to maturity of 18 months and a weighted average LTV ratio of 64%. (2) Weighted average is calculated based on the interest bearing principal balance of each loan within the related category. For loans acquired with servicing rights released by the seller, interest rates included in the calculation do not reflect loan servicing fees. For loans acquired with servicing rights retained by the seller, interest rates included in the calculation are net of servicing fees. (3) LTV represents the ratio of the total unpaid principal balance of the loan to the estimated value of the collateral securing the related loan as of the most recent date available, which may be the origination date. For Transitional loans, the LTV presented is the ratio of the maximum unpaid principal balance of the loan, including unfunded commitments, to the estimated “after repaired” value of the collateral securing the related loan, where available. For certain Transitional loans, totaling $296.1 million and $223.2 million at June 30, 2023 and December 31, 2022, respectively, an after repaired valuation was not obtained and the loan was underwritten based on an “as is” valuation. The weighted average LTV of these loans based on the current unpaid principal balance and the valuation obtained during underwriting, is 69% and 70% at June 30, 2023 and December 31, 2022, respectively. Excluded from the calculation of weighted average LTV are certain low value loans secured by vacant lots, for which the LTV ratio is not meaningful. 60+ LTV has been calculated on a consistent basis.

Financing agreements held at fair value are reported at estimated fair value each period as a result of the Company’s fair value option election. The fair value option was not elected for financing agreements held at carrying value. Consequently, Total financing agreements as presented reflects a summation of balances reported at fair and carrying value. At June 30, 2023, the Company had $553.2 million of agreements with mark-to-market collateral provisions held at fair value, $440.1 million of agreements with non-mark-to-market collateral provisions held at fair value, and $3.1 billion of securitized debt held at fair value, with amortized cost bases of $553.2 million, $440.1 million, and $3.3 billion, respectively. At December 31, 2022, the Company had $884.5 million of agreements with mark-to-market collateral provisions held at fair value, $578.9 million of agreements with non-mark-to-market collateral provisions held at fair value, and $2.4 billion of securitized debt held at fair value, with amortized cost bases of $884.5 million, $578.9 million, and $2.6 billion, respectively. (2) Weighted average cost of funding reflects annualized quarter-to-date interest expense divided by average balance for the financing agreements. The cost of funding for the total financing agreements includes the impact of the net carry (the difference between swap interest income received and swap interest expense paid) on the Company’s Swaps. For the quarter ended June 30, 2023, this decreased the overall funding cost by 138 basis points, and for the quarter ended December 31, 2022, this decreased the overall funding cost by 84 basis points. The Company does not allocate the impact of the net carry by type of financing agreement.
