Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business Operations	Organization and Business Operations Invesco Mortgage Capital Inc. (the “Company” or “we”) is a Maryland corporation primarily focused on investing in, financing and managing mortgage-backed securities ("MBS”) and other mortgage-related assets. As of December 31, 2022, we were invested in: • residential mortgage-backed securities (“RMBS”) that are guaranteed by a U.S. government agency such as the Government National Mortgage Association (“Ginnie Mae”), or a federally chartered corporation such as the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”) (collectively “Agency RMBS”); • commercial mortgage-backed securities (“CMBS”) that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency CMBS”); • RMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency RMBS”); and • other real estate-related financing arrangements. During the periods presented in these consolidated financial statements, we also invested in: • CMBS that are guaranteed by a U.S. government agency such as Ginnie Mae or a federally chartered corporation such as Fannie Mae or Freddie Mac (collectively “Agency CMBS”); • credit risk transfer securities that are unsecured obligations issued by government-sponsored enterprises (“GSE CRT”); • a commercial mortgage loan; and • U.S. Treasury securities. We conduct our business through IAS Operating Partnership L.P. (the “Operating Partnership”) and have one operating segment. We are externally managed and advised by Invesco Advisers, Inc. (our “Manager”), a registered investment adviser and an indirect, wholly-owned subsidiary of Invesco Ltd. (“Invesco”), a leading independent global investment management firm. We elected to be taxed as a real estate investment trust (“REIT”) for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. We operate our business in a manner that permits our exclusion from the “Investment Company” definition under the Investment Company Act of 1940, as amended (the “1940 Act”).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Consolidation For all periods presented in these consolidated financial statements, common shares and per common share amounts have been adjusted on a retroactive basis to reflect our one-for-ten reverse stock split, which was effected following the close of business on June 3, 2022, unless otherwise noted. Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and consolidate the financial statements of the Company and its controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed and credit risk transfer securities and allowances for credit losses. Actual results may differ from those estimates. Translation of Foreign Currencies The functional currency of the Company and its subsidiaries is U.S. dollars. Transactions in foreign currencies are recorded at the rates of exchange prevailing on the date of the transactions. At each balance sheet date, monetary assets and liabilities that are denominated in foreign currencies are remeasured at the rates prevailing at the balance sheet date. Gains and losses arising on revaluation are included in other investment income (loss), net on the consolidated statements of operations. Our reporting currency is U.S. dollars. Upon consolidation, the assets and liabilities of our investment in an unconsolidated venture whose functional currency is the Euro is translated to U.S. dollars using the period-end exchange rates. Equity accounts are translated at historical rates, except for the change in retained earnings during the year, which is the result of the income statement translation process. Revenue and expense accounts are translated using the weighted average exchange rate during the period. The cumulative translation adjustments associated with the investment in the unconsolidated venture are recorded in accumulated other comprehensive income (loss), a component of consolidated stockholders’ equity. We have historically hedged foreign currency exposure with derivative financial instruments. Refer to Note 8 - “Derivatives and Hedging Activities” for further information. Fair Value Measurements We report our MBS and GSE CRTs and derivative assets and liabilities at fair value as determined by an independent pricing service. We generally obtain one price per instrument from our primary pricing service. If the primary pricing service cannot provide a price, we will seek a value from other pricing services. The pricing service uses two types of valuation approaches to determine the valuation of our various mortgage-backed and credit risk transfer securities: a market approach, which uses observable prices and other relevant information that is generated by market transactions involving identical or comparable assets or liabilities; and an income approach, which uses valuation techniques to convert future amounts to a single, discounted present value amount. In instances where sufficient market activity may not exist, the pricing service may utilize proprietary valuation models that may consider market transactions in comparable securities and the various relationships between securities in determining fair value and/or market characteristics to estimate relevant cash flows, which are then discounted to calculate the fair values. Observable inputs may include a combination of benchmark yields, executed trades, broker/dealer quotes, issuer spreads, bids, offers and benchmark securities. In addition, the valuation models utilized by pricing services may consider additional pool level information such as prepayment speeds, default frequencies and default severities, if applicable. We and the pricing service continuously monitor market indicators and economic events to determine whether they may have an impact on our valuations. The pricing service values interest rate swaps, currency forward contracts and to-be-announced securities (“TBAs”) under the market approach through the use of quoted prices available in an active market. Overrides of prices from pricing services are rare in the current market environment for the assets we hold. Examples of instances that would cause an override include if we recently traded the same security or there is an indication of market activity that would cause the pricing service price to no longer be indicative of fair value. In the rare instance where a price is adjusted, we have a control process to monitor the reason for such adjustment. To gain comfort that pricing service prices are representative of current market information, we compare the transaction prices of security purchases and sales to the valuation levels provided by the pricing services. Price differences exceeding pre-defined tolerance levels are identified and investigated and may be challenged. Trends are monitored over time and if there are indications that the valuations are not comparable to market activity, the pricing services are asked to provide detailed information regarding their methodology and inputs. Transparency tools are also available from the pricing services which help us understand data points and/or market inputs used for pricing securities. We also review daily price movements for interest rate swaps, currency forward contracts and TBAs. Price movements exceeding pre-defined tolerance levels are investigated using an alternate price from another pricing service as well as available market information. Based on our findings, the primary pricing service may be challenged, or in rare cases, overridden with an alternate pricing source. In addition, we perform due diligence procedures on all pricing services on at least an annual basis. A questionnaire is sent to pricing services which requests information such as changes in methodologies, business recovery preparedness, internal controls and confirmation that evaluations are generated based on market data. Physical visits are also made to each pricing service's office. Virtual visits may take place in lieu of physical visits given concerns surrounding the COVID-19 pandemic. An independent pricing service valued our commercial loan investment using a discounted cash flow analysis. The yield used in the discounted cash flow analysis was determined by comparing the features of the loan to the interest rates and terms required by lenders in the new loan origination market for similar loans and the yield required by investors acquiring mezzanine loans in the secondary market as well as a comparison of current market and collateral conditions to those present at origination. As described in Note 10 - “Fair Value of Financial Instruments,” we evaluate the source used to fair value our assets and liabilities and make a determination on its categorization within the fair value hierarchy. If the price of a security is obtained from quoted prices for identical instruments in active markets, the security is classified as a level 1 security. If the price of a security is obtained from quoted prices for similar instruments or model-derived valuations whose inputs are observable, the security is classified as a level 2 security. If the inputs appear to be unobservable, the security would be classified as a level 3 security. Transfers between levels, if any, are determined at the end of the reporting period. Mortgage-Backed and Credit Risk Transfer Securities We record our purchases of MBS and GSE CRTs on the trade date and report these securities at fair value as described above in the Fair Value Measurements section of this Note 2 to our consolidated financial statements. Approximately $4.7 billion or 99% of our MBS are accounted for under the fair value option as of December 31, 2022 (December 31, 2021: $7.7 billion or 99%). Under the fair value option, we recognize changes in fair value in our consolidated statements of operations as unrealized gains and losses. In our view, this election more appropriately reflects the results of our operations because fair value changes are accounted for in the same manner as fair value changes in our economic hedging instruments. We elected the fair value option for all MBS purchased on or after September 1, 2016, GSE CRTs purchased on or after August 24, 2015 and all RMBS interest-only securities. We classify the remaining balance of our MBS as available-for-sale ($42.5 million or 1% as of December 31, 2022; $70.2 million or 1% as of December 31, 2021). Unrealized gains or losses on available-for-sale securities are recorded in accumulated other comprehensive income, a separate component of stockholders' equity, until sale or disposition of the investment. Upon sale or disposition, the cumulative gain or loss previously reported in stockholders' equity is recognized in income. Realized gains and losses from sales of MBS are determined based upon the specific identification method. GSE CRTs purchased before August 24, 2015 were reported at fair value and accounted for as hybrid financial instruments consisting of a debt host contract and an embedded derivative. Unrealized gains or losses arising from changes in fair value of the debt host contract, excluding other-than-temporary impairment, were recognized in accumulated other comprehensive income until sale or disposition of the investment. Upon sale or disposition of the debt host contract, the cumulative gain or loss previously reported in stockholders’ equity was recognized in income. Realized and unrealized gains or losses arising from changes in fair value of the embedded derivative were recognized in realized and unrealized credit derivative income (loss), net in our consolidated statements of operations. We elected the fair value option for GSE CRTs purchased on or after August 24, 2015 due to the complexities associated with bifurcation of GSE CRTs into a debt host contract and an embedded derivative. Realized gains and losses from sales of GSE CRTs were determined based upon the specific identification method. Our interest income recognition policies for MBS and GSE CRTs are described below in the Interest Income Recognition section of this Note 2 to our consolidated financial statements. Allowances for Credit Losses on Available-for-Sale Securities We are not required to measure expected credit losses for situations in which historic credit loss information, adjusted for current conditions and reasonable and supportable forecasts, results in an expectation that nonpayment of the amortized cost basis is zero. We consider our Agency portfolio to have zero loss expectation because (i) there have been no historical credit losses, (ii) full and timely payment of principal and interest is guaranteed by the GSEs and (iii) the yields, while not risk free, generally trade based on prepayment and liquidity risk as opposed to credit risk. For non-Agency RMBS and non-Agency CMBS, we use a discounted cash flow method to estimate and recognize an allowance for credit losses. We calculate the allowance for credit losses as the difference between the investment's amortized cost basis and expected cash flows discounted at the effective interest rate used to recognize interest income on the investment. In developing an expectation of credit losses, we use internal models that analyze the loans underlying each investment and evaluate factors including, but not limited to, delinquency status, loan-to-value ratios, borrower credit scores, occupancy status and geographic concentration. We place reliance on these internal models in determining credit quality. We record an allowance for credit losses as a contra-asset on the consolidated balance sheets and a provision for credit losses in the consolidated statements of operations. Credit losses are accreted into earnings over time at the effective interest rate used to recognize interest income. Subsequent favorable or adverse changes in the amount of expected credit losses are recognized immediately in earnings. If the allowance for credit losses has been reduced to zero, we reflect the remaining favorable changes as a prospective adjustment to the effective interest rate of the investment. The allowance for credit losses is limited to the amount by which the investment’s amortized cost exceeds fair value. When the allowance for credit losses is limited, the effective interest rate used to recognize interest income and accrete credit losses is prospectively adjusted. We do not record an allowance for credit losses when an investment’s fair value exceeds its amortized cost. Recoveries of amounts previously written off relating to improvements in cash flows are recognized in earnings when received. We record provisions for credit losses, reductions in provisions for credit losses, accretion of credit losses, and recoveries of amounts previously written off within (increase) decrease in provision for credit losses in our consolidated statements of operations. When we determine that we intend to sell, or more likely than not will be required to sell, an available-for-sale security in an unrealized loss position before we recover its amortized cost, we write off any allowance for credit losses and write down the investment’s amortized cost to its fair value. We record the write off of the allowance for credit losses within (increase) decrease in provision for credit losses on our consolidated statements of operations and write down of the available-for-sale security within gain (loss) on investments, net in our consolidated statements of operations. We present accrued interest receivable separately from our investment portfolio on our consolidated balance sheets. We do not estimate an allowance for credit losses on accrued interest receivable because we write off accrued interest receivable as a reduction to interest income if it is not received when due. U.S. Treasury Securities U.S. Treasury securities are classified as trading securities and reported at fair value on our consolidated balance sheets. Purchases of U.S. Treasury Securities are recorded on the trade date. Changes in the fair value of U.S. Treasury securities are recognized within gain (loss) on investments, net in our consolidated statements of operations. Coupon interest income is accrued based on the outstanding principal balance of the securities and their contractual terms. Interest income on U.S. Treasury securities is recognized within mortgage-backed and other securities interest income on our consolidated statements of operations. Commercial Loan Held-For-Investment We reported our commercial loan investment at fair value as described in the Fair Value Measurements section of this Note 2 to the consolidated financial statements. We recorded changes in fair value within gain (loss) on investments, net in our consolidated statements of operations. Interest Income Recognition Mortgage-Backed Securities Interest income on MBS is accrued based on the outstanding principal or notional balance of the securities and their contractual terms. Premiums or discounts are amortized or accreted into interest income over the life of the investment using the effective interest method. Interest income on our MBS where we may not recover substantially all of our initial investment is based on estimated future cash flows. We estimate future expected cash flows at the time of purchase and determine the effective interest rate based on these estimated cash flows and our purchase price. Over the life of the investments, we update these estimated future cash flows and compute a revised yield based on the current amortized cost of the investment, unless those changes are reflected in an allowance for credit losses. In situations where an allowance for credit losses is limited by the fair value of the investment, we compute the yield as the rate that equates expected future cash flows to the current fair value of the investment. In estimating these future cash flows, there are a number of assumptions that are subject to uncertainties and contingencies, including but not limited to the rate and timing of principal payments (prepayments, repurchases, defaults and liquidations), the pass through or coupon rate, and interest rate fluctuations. These uncertainties and contingencies are difficult to predict and are subject to future events that may impact our estimate and our interest income. Changes in our original or most recent cash flow projections may result in a prospective change in interest income recognized on these securities, or the amortized cost of these securities, including write-offs of amortized cost when certain amounts are deemed uncollectible. For non-Agency RMBS not of high credit quality, when actual cash flows vary from expected cash flows, the difference is recorded as an adjustment to the amortized cost of the security, unless those changes are reflected in an allowance for credit losses, and the security's yield is revised prospectively. For Agency RMBS and Agency CMBS that cannot be prepaid in such a way that we would not recover substantially all of our initial investment, interest income recognition is based on contractual cash flows. We do not estimate prepayments in applying the effective interest method. Credit Risk Transfer Securities Interest income on GSE CRTs purchased before August 24, 2015 was accrued based on the coupon rate of the debt host contract which reflected the credit risk of GSE unsecured senior debt with a similar maturity. Premiums or discounts associated with the purchase of GSE CRTs were amortized or accreted into interest income over the life of the debt host contract using the effective interest method. The difference between the coupon rate on the hybrid instrument and the coupon rate on the debt host contract was considered premium income associated with the embedded derivative and was recorded in realized and unrealized credit derivative income (loss), net in our consolidated statements of operations. Interest income on GSE CRTs purchased on or after August 24, 2015 was based on estimated future cash flows. Commercial and Other Loans We recognize interest income from commercial and other loans when earned and deemed collectible, or until a loan becomes past due based on the terms of the loan agreement. Any related origination fees or costs on commercial and other loans for which we have elected the fair value option are recognized immediately in earnings. Interest received after a loan becomes past due or impaired is used to reduce the outstanding loan principal balance. When a delinquent loan previously placed on nonaccrual status has cured, meaning all delinquent principal and interest have been remitted by the borrower, the loan is placed back on accrual status. Alternately, loans that have been individually impaired may be placed back on accrual status if restructured and after the loan is considered re-performing. A restructured loan is considered re-performing when the loan has been current for at least 12 months. Cash and Cash Equivalents We consider all highly liquid investments that have original or remaining maturity dates of three months or less when purchased to be cash equivalents. At December 31, 2022, we had cash and cash equivalents in excess of the FDIC deposit insurance limit of $250,000 per institution. We mitigate our risk of loss by actively monitoring our counterparties. Restricted Cash Restricted cash represents cash posted with counterparties as collateral for various derivative instruments. Cash posted with counterparties as collateral is not available for general corporate purposes. Due from Counterparties / Collateral Held Payable Due from counterparties represents cash posted with our counterparties as collateral for our derivatives and repurchase agreements. Collateral held payable represents cash posted with us by counterparties as collateral under our derivatives and repurchase agreements. If we receive collateral other than cash from our counterparties, such assets are not included in our consolidated balance sheets. If we either sell such assets or pledge the assets as collateral under a repurchase agreement, the cash received and the corresponding liability is reflected on the consolidated balance sheets. Investment Related Receivable / Investment Related Payable Investment related receivable consists of receivables for mortgage-backed securities that we have sold but have not settled with the buyer and accrued interest and principal paydowns on mortgage-backed securities. Investment related payable consists of liabilities for mortgage-backed securities that we have purchased but have not settled with the seller. Investments in Unconsolidated Ventures Our non-controlling investments in unconsolidated ventures are included in other assets in our consolidated balance sheets and are accounted for under the equity method. Capital contributions, distributions, profits and losses of the entities are allocated in accordance with the terms of the entities’ operating agreements. Such allocations may differ from the stated percentage interests, if any, as a result of preferred returns and allocation formulas as described in the entities' operating agreements. Repurchase Agreements We have financed our purchases of mortgage-backed and credit risk transfer securities primarily through the use of repurchase agreements. Repurchase agreements are treated as collateralized financing transactions and are carried at their contractual amounts, including accrued interest, as specified in the respective agreements. We record the mortgage-backed securities and the related repurchase agreement financing on a gross basis in our consolidated balance sheets, and the corresponding interest income and interest expense on a gross basis in our consolidated statements of operations. Secured Loans Our wholly-owned subsidiary, IAS Services LLC, was a member of the Federal Home Loan Bank of Indianapolis (“FHLBI”). As a member of the FHLBI, IAS Services LLC borrowed funds from the FHLBI in the form of secured advances. FHLBI advances were treated as secured financing transactions and carried at their contractual amounts. During the year ended December 31, 2020, we fully repaid our outstanding secured loans from the FHLBI and terminated our membership. IAS Services LLC was dissolved in December 2020. Dividends Payable Dividends payable represent dividends declared at the balance sheet date that are payable to common stockholders and preferred stockholders. Earnings (Loss) per Share We calculate basic earnings (loss) per share by dividing net income (loss) attributable to common stockholders for the period by the weighted-average number of shares of our common stock outstanding for that period. Diluted earnings per share takes into account the effect of dilutive instruments, such as unvested restricted stock awards, and uses the average share price for the period in determining the number of incremental shares that are to be added to the weighted-average number of shares outstanding. Share-Based Compensation Under the terms of our amended and restated 2009 Equity Incentive Plan (the “Incentive Plan”), our independent directors are eligible to receive stock awards as part of their compensation for serving as directors, In addition, we may compensate the officers and employees of our Manager and its affiliates under the Incentive Plan under the terms of our management agreement. Share-based compensation arrangements may include share options, restricted and non-restricted share awards, performance-based awards and share appreciation rights. Compensation related to stock awards is recognized in the consolidated financial statements based on the fair value of the equity or liability instruments issued on the date of grant. Underwriting Commissions and Offering Costs Underwriting commissions and direct costs incurred in connection with our common and preferred stock offerings are recorded as a reduction of additional paid in capital and preferred stock, respectively. Comprehensive Income Our comprehensive income consists of net income, as presented in the consolidated statements of operations, adjusted for unrealized gains and losses on MBS purchased before September 1, 2016 and the debt host contract associated with GSE CRTs purchased before August 24, 2015; reclassification of unrealized losses on available-for-sale securities to (increase) decrease in provision for credit losses; reclassification of amortization of net deferred gains and losses on de-designated interest rate swaps to repurchase agreements interest expense and currency translation adjustments on an investment in an unconsolidated venture. Unrealized gains and losses on our MBS purchased before September 1, 2016 and the debt host contract associated with GSE CRTs purchased before August 24, 2015 are reclassified into net income upon their sale. Accounting for Derivative Financial Instruments We record all derivatives on our consolidated balance sheets at fair value. At the inception of a derivative contract, we determine whether the instrument will be part of a qualifying hedge accounting relationship or whether we will account for the contract as a trading instrument. We have elected not to apply hedge accounting to all new derivative contracts entered into after January 1, 2014. Changes in the fair value of our derivatives are recorded in gain (loss) on derivative instruments, net in our consolidated statements of operations. Net interest paid or received under our interest rate swaps is also recognized in gain (loss) on derivative instruments, net in our consolidated statements of operations. Before 2014, we applied hedge accounting to our interest rate swap agreements. Effective December 31, 2013, we voluntarily discontinued hedge accounting for our interest rate swap agreements by de-designating the interest rate swaps as cash flow hedges. As long as we expect the forecasted transactions that were being hedged (i.e., rollovers of our repurchase agreement borrowings) to still occur, the balance recorded in accumulated other comprehensive income (loss) (“AOCI”) from the interest rate swap activity through December 31, 2013 will remain in AOCI and be recognized in our consolidated statements of operations as interest expense over the remaining term of the interest rate swaps. Prior to December 31, 2020, we were a party to hybrid financial instruments that contained embedded derivative instruments and for which we did not elect the fair value option. We assessed at inception whether the economic characteristics of the embedded derivative instruments were clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the debt host contract), whether the financial instrument was remeasured to fair value through earnings and whether a separate instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it was determined that (1) the embedded instrument possessed economic characteristics that were not clearly and closely related to the economic characteristics of the debt host contract, (2) the financial instrument was not remeasured to fair value through earnings and (3) a separate instrument with the same terms would qualify as a derivative instrument, the embedded instrument qualified as an embedded derivative that was separated from the debt host contract. The embedded derivative was recorded at fair value, and changes in fair value were recorded in realized and unrealized credit derivative income (loss), net in our consolidated statements of operations. We evaluate the terms and conditions of our holdings of swaptions, currency forward contracts and TBAs to determine if an instrument has the characteristics of an investment or should be considered a derivative under U.S. GAAP. Accordingly, swaptions, currency forward contracts and TBAs having the characteristics of derivatives are accounted for at fair value with such changes recognized in gain (loss) on derivative instruments, net in the consolidated statements of operations. The fair value of these swaptions, currency forward contracts and TBAs is included in derivative assets or derivative liabilities on the consolidated balance sheets. Income Taxes We elected to be taxed as a REIT commencing with our taxable year ended December 31, 2009. Accordingly, we will generally not be subject to U.S. federal and applicable state and local corporate income tax to the extent that we make qualifying distributions to our stockholders, and provided we satisfy on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution and stock ownership tests. If we fail to qualify as a REIT and do not qualify for certain statutory relief provisions, we will be subject to U.S. federal, state and local income taxes and may be precluded from qualifying as a REIT for the four taxable years following the year in which we lost our REIT qualification. Accordingly, our failure to qualify as a REIT could have a material adverse impact on our results of operations and amounts available for distribution to stockholders. Our dividends paid deduction for qualifying dividends to our stockholders is computed using our REIT taxable income as opposed to net income reported on the consolidated financial statements. REIT taxable income will generally differ from net income because the determination of REIT taxable income is based on tax regulations and not financial accounting principles. We have elected to treat one of our subsidiaries as taxable REIT subsidiaries (“TRS”). In general, a TRS may hold assets and engage in activities that we cannot hold or engage in directly and generally may engage in any real estate or non-real estate-related business. A TRS is subject to U.S. federal, state and local corporate income taxes. Our TRS did not generate material taxable income for the years ended December 31, 2022, 2021 and 2020. We do not have any accruals for uncertain tax positions. We would recognize interest and penalties related to uncertain tax positions, if any, as income tax expense, which would be included in general and administrative expenses.

Refer to Note 2 - “Summary of Significant Accounting Policies - Fair Value Measurements” for a description of how we determine fair value. Agency RMBS collateral pledged is included in mortgage-backed securities on our consolidated balance sheets. Cash collateral pledged on centrally cleared interest rate swaps and currency forward contracts is classified as restricted cash on our consolidated balance sheets. Cash collateral pledged on repurchase agreements and TBAs accounted for as derivatives is classified as due from counterparties on our consolidated balance sheets. Cash collateral held that is not restricted for use is included in cash and cash equivalents on our consolidated balance sheets and the liability to return the collateral is included in collateral held payable. Non-cash collateral held is only recognized if the counterparty defaults or if we sell the pledged collateral. As of December 31, 2022 and 2021, we did not recognize any non-cash collateral held on our consolidated balance sheets. $ in thousands As of Collateral Pledged December 31, 2022 December 31, 2021 Repurchase agreements: Agency RMBS 4,439,583 7,326,175 Cash — 3,527 Total repurchase agreements collateral pledged 4,439,583 7,329,702 Derivative instruments: Cash 1,584 4,458 Restricted cash 103,246 219,918 Total derivative instruments collateral pledged 104,830 224,376 Total collateral pledged: Agency RMBS 4,439,583 7,326,175 Cash 1,584 7,985 Restricted cash 103,246 219,918 Total collateral pledged 4,544,413 7,554,078 Collateral Held December 31, 2022 December 31, 2021 Repurchase agreements: Cash 4,892 — Non-cash collateral 7,216 248 Total repurchase agreements collateral held 12,108 248 Derivative instruments: Cash — 280 Total derivative instruments collateral held — 280 Total collateral held: Cash 4,892 280 Non-cash collateral 7,216 248 Total collateral held 12,108 528 Repurchase Agreements Collateral pledged with our repurchase agreement counterparties is segregated in our books and records. The repurchase agreement counterparties have the right to resell and repledge the collateral posted but have the obligation to return the pledged collateral, or substantially the same collateral if agreed to by us, upon maturity of the repurchase agreement. Under the repurchase agreements, the respective lender retains the contractual right to mark the underlying collateral to fair value. We would be required to provide additional collateral to fund margin calls if the value of pledged assets declined. We intend to maintain a level of liquidity that will enable us to meet margin calls. As of December 31, 2022 and 2021, our repurchase agreement collateral ratio (MBS pledged as collateral/ repurchase agreement amount outstanding) was 105%. Interest Rate Swaps As of December 31, 2022 and 2021, all of our interest rate swaps were centrally cleared by a registered clearing organization such as the Chicago Mercantile Exchange (“CME”) and LCH Limited (“LCH”) through a Futures Commission Merchant (“FCM”). We are required to pledge initial margin and daily variation margin for our centrally cleared interest rate swaps that is based on the fair value of our contracts as determined by our FCM. Collateral pledged with our FCM is segregated in our books and records and can be in the form of cash or securities. Daily variation margin for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral and is recorded as gain (loss) on derivative instruments, net in our consolidated statements of operations. Certain of our FCM agreements include cross default provisions. TBAs and Currency Forward Contracts

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, credit and foreign exchange rate risk primarily by managing the amount, sources, and duration of our investments, borrowings, and the use of derivative financial instruments. Specifically, we use derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates or foreign exchange rates. Our derivative financial instruments are used to manage differences in the amount, timing, and duration of our known or expected cash receipts and our known or expected cash payments principally related to our investments and borrowings. The following table summarizes changes in the notional amount of our derivative instruments during 2022: $ in thousands Notional Amount as of December 31, 2021 Additions Settlement, Notional Amount as Interest Rate Swaps (1)(2) 8,050,000 10,075,000 (9,975,000) 8,150,000 Currency Forward Contracts 13,596 23,485 (37,081) — TBA Purchase Contracts 1,600,000 20,072,000 (21,272,000) 400,000 TBA Sale Contracts — (21,672,000) 21,272,000 (400,000) Total 9,663,596 8,498,485 (10,012,081) 8,150,000 (1) Does not include interest rate swaps with forward start dates. See below for additional details on our interest rate swaps with forward start dates. (2) Notional amount as of December 31, 2022 includes $5.8 billion of interest rate swaps whereby we pay interest at a fixed rate and receive interest at a floating rate and $2.4 billion of interest rate swaps whereby we pay interest at a floating rate and receive interest at a fixed rate. Notional amount as of December 31, 2021 includes $6.3 billion of interest rate swaps whereby we pay interest at a fixed rate and receive interest at a floating rate and $1.8 billion of interest rate swaps whereby we pay interest at a floating rate and receive interest at a fixed rate. Refer to Note 7 - “Collateral Positions” for further information regarding our collateral pledged to and received from our derivative counterparties. Interest Rate Swaps Our repurchase agreements are usually settled on a short-term basis ranging from one month to six months. At each settlement date, we typically refinance each repurchase agreement at the market interest rate at that time. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposures to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy. Under the terms of the majority of our interest rate swap contracts, we make fixed-rate payments to a counterparty in exchange for the receipt of floating-rate amounts over the life of the agreements without exchange of the underlying notional amount. To a lesser extent, we also enter into interest rate swap contracts whereby we make floating-rate payments to a counterparty in exchange for the receipt of fixed-rate amounts as part of our overall risk management strategy. Amounts recorded in accumulated other comprehensive income (“AOCI”) before we discontinued cash flow hedge accounting for our interest rate swaps are reclassified to interest expense on repurchase agreements on the consolidated statements of operations as interest is accrued and paid on the related repurchase agreements over the remaining life of the interest rate swap agreements. We reclassified $19.7 million as a decrease to interest expense for the year ended December 31, 2022 (2021: $22.0 million as a decrease; 2020: $23.8 million as a decrease). As of December 31, 2022, $10.4 million (2021: $30.1 million) of net unrealized gains on discontinued cash flow hedges are still included in accumulated other comprehensive income. We expect to reclassify the remaining amount of net unrealized gains recorded in AOCI as a decrease to interest expense on repurchase agreements on the consolidated statements of operations in 2023. As of December 31, 2022 and 2021, we had interest rate swaps whereby we pay interest at a fixed rate and receive floating interest based on the secured overnight financing rate (“SOFR”) with the following maturities outstand ing, excluding interest rate swaps with forward start dates. $ in thousands As of December 31, 2022 Maturities Notional Amount Weighted Average Fixed Pay Rate Weighted Average Floating Receive Rate Weighted Average Years to Maturity Less than 3 years 1,550,000 0.09 % 4.30 % 2.2 3 to 5 years 1,475,000 0.27 % 4.30 % 4.7 5 to 7 years 850,000 0.38 % 4.30 % 6.2 7 to 10 years 1,425,000 0.55 % 4.30 % 7.8 Greater than 10 years 500,000 1.92 % 4.30 % 19.2 Total 5,800,000 0.45 % 4.30 % 6.3 $ in thousands As of December 31, 2021 Maturities Notional Amount Weighted Average Fixed Pay Rate Weighted Average Floating Receive Rate Weighted Average Years to Maturity Less than 3 years 1,000,000 0.06 % 0.05 % 2.6 3 to 5 years 1,250,000 0.12 % 0.05 % 3.6 5 to 7 years 2,225,000 0.32 % 0.05 % 5.9 7 to 10 years 1,825,000 0.52 % 0.05 % 8.6 Total 6,300,000 0.30 % 0.05 % 5.7 As of December 31, 2022, we held $975.0 million notional amount of interest rate swaps with forward start dates that will receive floating interest based on SOFR (December 31, 2021: $1.3 billion). As of December 31, 2022, these interest rate swaps had a weighted average maturity of 16.5 years (December 31, 2021: 20.8 years) and a weighted average fixed pay rate of 0.89% (December 31, 2021: 0.99%).

As of December 31, 2022, these interest rate swaps had a weighted average maturity of 16.0 years and a weighted average fixed receive rate of 2.63%. We did not hold any such interest rate swaps as of December 31, 2021. Swaptions and Currency Forward Contracts We periodically purchase interest rate swaptions to help mitigate the potential impact of increases or decreases in interest rates on the performance of our Agency RMBS portfolio (referred to as “convexity risk”). The interest rate swaptions provide us the option to enter into interest rate swap agreements for a predetermined notional amount, stated term and pay and receive interest rates in the future. The premium paid for interest rate swaptions is reported as a derivative asset in our consolidated balance sheets. The premium is valued at an amount equal to the fair value of the swaption that would have the effect of closing the position adjusted for nonperformance risk, if any. The difference between the premium and the fair value of the swaption is reported in gain (loss) on derivative instruments, net in our consolidated statements of operations. If an interest rate swaption expires unexercised, the loss on the interest rate swaption would equal the premium paid. If we sell or exercise an interest rate swaption, the realized gain or loss on the interest rate swaption would equal the difference between the cash or the fair value of the underlying interest rate swap received and the premium paid. We use currency forward contracts to help mitigate the potential impact of changes in foreign currency exchange rates on our investments denominated in foreign currencies. We recognize realized and unrealized gains and losses associated with the purchases or sales of currency forward contracts in gain (loss) on derivative instruments, net in our consolidated statements of operations. We did not have any currency forward contracts outstanding as of December 31, 2022. As of December 31, 2021 we had $13.6 million of notional amount of currency forward contracts related to an investment in an unconsolidated venture denominated in euro. Credit Derivatives Our GSE CRTs purchased before August 24, 2015 were accounted for as hybrid financial instruments consisting of a debt host contract and an embedded credit derivative. Embedded derivatives associated with GSE CRTs were recorded within mortgage-backed and credit risk transfer securities, at fair value, on our consolidated balance sheets. We sold all of our GSE CRT investments that were accounted for as hybrid financial instruments in 2020. TBAs We primarily use TBAs that we do not intend to physically settle on the contractual settlement date as an alternative means of investing in and financing Agency RMBS.

Offsetting [Abstract]
Offsetting Assets and Liabilities	Offsetting Assets and Liabilities Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of offset under master netting arrangements (or similar agreements) in the event of default or in the event of bankruptcy of either party to the transactions. Assets and liabilities subject to such arrangements are presented on a gross basis in the consolidated balance sheets. The following tables present information about the assets and liabilities that are subject to master netting arrangements (or similar agreements) and can potentially be offset on our consolidated balance sheets at December 31, 2022 and December 31, 2021. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. Our derivative asset of $20,000 at December 31, 2022 (December 31, 2021: liability of $11.4 million) related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.

Cash collateral pledged on our centrally cleared interest rate swaps is settled against the fair value of these swaps and is therefore excluded from the tables above. We held no cash collateral on our derivatives as of December 31, 2022 and $280,000 as of December 31, 2021. (3) The fair value of securities pledged against our borrowings under repurchase agreements was $4.4 billion and $7.3 billion as of December 31, 2022 and December 31, 2021, respectively. We pledged no cash collateral and $3.5 million of cash collateral under repurchase agreements as of December 31, 2022 and December 31, 2021, respectively. We held cash collateral of $4.9 million and no cash collateral under repurchase agreements as of December 31, 2022 and December 31, 2021, respectively.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments A three-level valuation hierarchy exists for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. The three levels are defined as follows: • Level 1 Inputs – Quoted prices for identical instruments in active markets. • Level 2 Inputs – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3 Inputs – Instruments with primarily unobservable value drivers. The following tables present our assets and liabilities measured at fair value on a recurring basis.

(2) Investments in unconsolidated ventures are valued using the net asset value (“NAV”) as a practical expedient and are not subject to redemption, although investors may sell or transfer their interest at the approval of the general partner of the underlying funds. As of December 31, 2022, our unconsolidated ventures were in liquidation and plan to sell or settle their remaining investments as expeditiously as possible. (3) We used an independent third party appraisal to value our commercial loan investment. The following table shows a reconciliation of the beginning and ending fair value measurements of our commercial loan investment, which we valued utilizing Level 3 inputs.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Our Manager is at all times subject to the supervision and oversight of our board of directors and has only such functions and authority as we delegate to it. Under the terms of our management agreement, our Manager and its affiliates provide us with our management team, including our officers and appropriate support personnel. Each of our officers is an employee of our Manager or one of its affiliates. We do not have any employees. Our Manager is not obligated to dedicate any of its employees exclusively to us, nor is our Manager obligated to dedicate any specific portion of time to our business. During the year ended December 31, 2022, we reimbursed our Manager $1.5 million (2021: $1.1 million; 2020: $1.1 million) for costs of support personnel. Management Fee We pay our Manager a fee equal to 1.50% of our stockholders' equity per annum. For purposes of calculating the management fee, stockholders' equity is calculated as average month-end stockholders' equity for the prior calendar quarter as determined in accordance with U.S. GAAP. Stockholders' equity may exclude one-time events due to changes in U.S. GAAP and certain non-cash items upon approval by a majority of our independent directors. We do not pay any management fees on our investments in unconsolidated ventures that are managed by an affiliate of our Manager. Expense Reimbursement We are required to reimburse our Manager for operating expenses incurred on our behalf, including directors and officers insurance, accounting services, auditing and tax services, legal services, filing fees, and miscellaneous general and administrative costs. Our reimbursement obligation is not subject to any dollar limitation. The following table summarizes the costs incurred on our behalf by our Manager for the years ended December 31, 2022, 2021 and 2020.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Preferred Stock In June 2021, we redeemed all issued and outstanding shares of our Series A Preferred Stock for $140.0 million plus accrued and unpaid dividends. The excess of the consideration transferred over carrying value was accounted for as a deemed dividend and resulted in a reduction of $4.7 million in net income (loss) attributable to common stockholders during the year ended December 31, 2021. In May 2022, our board of directors approved a share repurchase program for our Series B and Series C Preferred Stock. During the year ended December 31, 2022, we repurchased and retired 1,662,366 shares of Series B Preferred Stock and 3,683,530 shares of Series C Preferred Stock and recorded a gain on repurchase and retirement of preferred stock of $14.2 million. As of December 31, 2022, we had authority to purchase 1,337,634 additional shares of our Series B Preferred Stock and 1,316,470 additional shares of our Series C Preferred Stock under the current share repurchase program. Holders of our Series B Preferred Stock are entitled to receive dividends at an annual rate of 7.75% of the liquidation preference of $25.00 per share or $1.9375 per share per annum until December 27, 2024. After December 27, 2024, holders are entitled to receive dividends at a floating rate equal to three-month London Interbank Offered Rate ("LIBOR") plus a spread of 5.18% of the $25.00 liquidation preference per annum. Dividends are cumulative and payable quarterly in arrears. Holders of our Series C Preferred Stock are entitled to receive dividends at an annual rate of 7.50% of the liquidation preference of $25.00 per share or $1.875 per share per annum until September 27, 2027. After September 27, 2027, holders are entitled to receive dividends at a floating rate equal to three-month LIBOR plus a spread of 5.289% of the $25.00 liquidation preference per annum. Dividends are cumulative and payable quarterly in arrears. The United Kingdom Financial Conduct Authority, which regulates LIBOR, announced that it will cease to publish three-month USD LIBOR settings on July 1, 2023. We do not currently intend to amend our Series B or Series C Preferred Stock to change the existing USD LIBOR cessation fallback language. We have the option to redeem shares of our Series B Preferred Stock after December 27, 2024 and shares of our Series C Preferred Stock after September 27, 2027 for $25.00 per share, plus any accumulated and unpaid dividends through the date of the redemption. Shares of Series B and Series C Preferred Stock are not redeemable, convertible into or exchangeable for any other property or any other securities of the Company before those times, except under circumstances intended to preserve our qualification as a REIT or upon the occurrence of a change in control. Common Stock In May 2022, our board of directors approved a one-for-ten reverse split of outstanding shares of our common stock. The reverse stock split was effected following the close of business on June 3, 2022 (the "Effective Time"). At the Effective Time, every ten issued and outstanding shares of our common stock were converted into one share of our common stock. No fractional shares were issued in connection with the reverse stock split. Instead, each stockholder holding fractional shares received cash, in lieu of such fractional shares, in an amount determined based on the closing price of our common stock at the Effective Time. The reverse stock split applied to all of our outstanding shares of common stock and did not affect any stockholder’s ownership percentage of our common stock, except for changes resulting from the payment of cash for fractional shares. During the year ended December 31, 2022, we sold 5,686,598 shares (2021: 5,574,402 shares) of common stock in at-the-market transactions under our equity distribution agreements for proceeds of $81.6 million (2021: $180.5 million) net of approximately $1.3 million (2021: $2.6 million) in commissions and fees. We did not have any remaining shares authorized under our at-the-market program as of December 31, 2022. During the years ended December 31, 2022 and December 31, 2021, we did not repurchase any shares of our common stock. As of December 31, 2022, we had authority to purchase 1,816,398 shares of our common stock through our share repurchase program. In May 2022, we granted 32,571 restricted shares of common stock to our independent directors. The restricted shares will become unrestricted shares of common stock on the first anniversary of the grant date unless forfeited, subject to certain conditions that accelerate vesting.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation For all periods presented in these consolidated financial statements, common shares and per common share amounts have been adjusted on a retroactive basis to reflect our one-for-ten reverse stock split, which was effected following the close of business on June 3, 2022, unless otherwise noted.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed and credit risk transfer securities and allowances for credit losses. Actual results may differ from those estimates.
Translation of Foreign Currencies	Translation of Foreign Currencies The functional currency of the Company and its subsidiaries is U.S. dollars. Transactions in foreign currencies are recorded at the rates of exchange prevailing on the date of the transactions. At each balance sheet date, monetary assets and liabilities that are denominated in foreign currencies are remeasured at the rates prevailing at the balance sheet date. Gains and losses arising on revaluation are included in other investment income (loss), net on the consolidated statements of operations. Our reporting currency is U.S. dollars. Upon consolidation, the assets and liabilities of our investment in an unconsolidated venture whose functional currency is the Euro is translated to U.S. dollars using the period-end exchange rates. Equity accounts are translated at historical rates, except for the change in retained earnings during the year, which is the result of the income statement translation process. Revenue and expense accounts are translated using the weighted average exchange rate during the period. The cumulative translation adjustments associated with the investment in the unconsolidated venture are recorded in accumulated other comprehensive income (loss), a component of consolidated stockholders’ equity.
Fair Value Measurements	Fair Value Measurements We report our MBS and GSE CRTs and derivative assets and liabilities at fair value as determined by an independent pricing service. We generally obtain one price per instrument from our primary pricing service. If the primary pricing service cannot provide a price, we will seek a value from other pricing services. The pricing service uses two types of valuation approaches to determine the valuation of our various mortgage-backed and credit risk transfer securities: a market approach, which uses observable prices and other relevant information that is generated by market transactions involving identical or comparable assets or liabilities; and an income approach, which uses valuation techniques to convert future amounts to a single, discounted present value amount. In instances where sufficient market activity may not exist, the pricing service may utilize proprietary valuation models that may consider market transactions in comparable securities and the various relationships between securities in determining fair value and/or market characteristics to estimate relevant cash flows, which are then discounted to calculate the fair values. Observable inputs may include a combination of benchmark yields, executed trades, broker/dealer quotes, issuer spreads, bids, offers and benchmark securities. In addition, the valuation models utilized by pricing services may consider additional pool level information such as prepayment speeds, default frequencies and default severities, if applicable. We and the pricing service continuously monitor market indicators and economic events to determine whether they may have an impact on our valuations. The pricing service values interest rate swaps, currency forward contracts and to-be-announced securities (“TBAs”) under the market approach through the use of quoted prices available in an active market. Overrides of prices from pricing services are rare in the current market environment for the assets we hold. Examples of instances that would cause an override include if we recently traded the same security or there is an indication of market activity that would cause the pricing service price to no longer be indicative of fair value. In the rare instance where a price is adjusted, we have a control process to monitor the reason for such adjustment. To gain comfort that pricing service prices are representative of current market information, we compare the transaction prices of security purchases and sales to the valuation levels provided by the pricing services. Price differences exceeding pre-defined tolerance levels are identified and investigated and may be challenged. Trends are monitored over time and if there are indications that the valuations are not comparable to market activity, the pricing services are asked to provide detailed information regarding their methodology and inputs. Transparency tools are also available from the pricing services which help us understand data points and/or market inputs used for pricing securities. We also review daily price movements for interest rate swaps, currency forward contracts and TBAs. Price movements exceeding pre-defined tolerance levels are investigated using an alternate price from another pricing service as well as available market information. Based on our findings, the primary pricing service may be challenged, or in rare cases, overridden with an alternate pricing source. In addition, we perform due diligence procedures on all pricing services on at least an annual basis. A questionnaire is sent to pricing services which requests information such as changes in methodologies, business recovery preparedness, internal controls and confirmation that evaluations are generated based on market data. Physical visits are also made to each pricing service's office. Virtual visits may take place in lieu of physical visits given concerns surrounding the COVID-19 pandemic. An independent pricing service valued our commercial loan investment using a discounted cash flow analysis. The yield used in the discounted cash flow analysis was determined by comparing the features of the loan to the interest rates and terms required by lenders in the new loan origination market for similar loans and the yield required by investors acquiring mezzanine loans in the secondary market as well as a comparison of current market and collateral conditions to those present at origination. As described in Note 10 - “Fair Value of Financial Instruments,” we evaluate the source used to fair value our assets and liabilities and make a determination on its categorization within the fair value hierarchy. If the price of a security is obtained from quoted prices for identical instruments in active markets, the security is classified as a level 1 security. If the price of a security is obtained from quoted prices for similar instruments or model-derived valuations whose inputs are observable, the security is classified as a level 2 security. If the inputs appear to be unobservable, the security would be classified as a level 3 security. Transfers between levels, if any, are determined at the end of the reporting period.
Mortgage-Backed and Credit Risk Transfer Securities	Mortgage-Backed and Credit Risk Transfer Securities We record our purchases of MBS and GSE CRTs on the trade date and report these securities at fair value as described above in the Fair Value Measurements section of this Note 2 to our consolidated financial statements. Approximately $4.7 billion or 99% of our MBS are accounted for under the fair value option as of December 31, 2022 (December 31, 2021: $7.7 billion or 99%). Under the fair value option, we recognize changes in fair value in our consolidated statements of operations as unrealized gains and losses. In our view, this election more appropriately reflects the results of our operations because fair value changes are accounted for in the same manner as fair value changes in our economic hedging instruments. We elected the fair value option for all MBS purchased on or after September 1, 2016, GSE CRTs purchased on or after August 24, 2015 and all RMBS interest-only securities. We classify the remaining balance of our MBS as available-for-sale ($42.5 million or 1% as of December 31, 2022; $70.2 million or 1% as of December 31, 2021). Unrealized gains or losses on available-for-sale securities are recorded in accumulated other comprehensive income, a separate component of stockholders' equity, until sale or disposition of the investment. Upon sale or disposition, the cumulative gain or loss previously reported in stockholders' equity is recognized in income. Realized gains and losses from sales of MBS are determined based upon the specific identification method. GSE CRTs purchased before August 24, 2015 were reported at fair value and accounted for as hybrid financial instruments consisting of a debt host contract and an embedded derivative. Unrealized gains or losses arising from changes in fair value of the debt host contract, excluding other-than-temporary impairment, were recognized in accumulated other comprehensive income until sale or disposition of the investment. Upon sale or disposition of the debt host contract, the cumulative gain or loss previously reported in stockholders’ equity was recognized in income. Realized and unrealized gains or losses arising from changes in fair value of the embedded derivative were recognized in realized and unrealized credit derivative income (loss), net in our consolidated statements of operations. We elected the fair value option for GSE CRTs purchased on or after August 24, 2015 due to the complexities associated with bifurcation of GSE CRTs into a debt host contract and an embedded derivative. Realized gains and losses from sales of GSE CRTs were determined based upon the specific identification method. Our interest income recognition policies for MBS and GSE CRTs are described below in the Interest Income Recognition section of this Note 2 to our consolidated financial statements. Allowances for Credit Losses on Available-for-Sale Securities We are not required to measure expected credit losses for situations in which historic credit loss information, adjusted for current conditions and reasonable and supportable forecasts, results in an expectation that nonpayment of the amortized cost basis is zero. We consider our Agency portfolio to have zero loss expectation because (i) there have been no historical credit losses, (ii) full and timely payment of principal and interest is guaranteed by the GSEs and (iii) the yields, while not risk free, generally trade based on prepayment and liquidity risk as opposed to credit risk. For non-Agency RMBS and non-Agency CMBS, we use a discounted cash flow method to estimate and recognize an allowance for credit losses. We calculate the allowance for credit losses as the difference between the investment's amortized cost basis and expected cash flows discounted at the effective interest rate used to recognize interest income on the investment. In developing an expectation of credit losses, we use internal models that analyze the loans underlying each investment and evaluate factors including, but not limited to, delinquency status, loan-to-value ratios, borrower credit scores, occupancy status and geographic concentration. We place reliance on these internal models in determining credit quality. We record an allowance for credit losses as a contra-asset on the consolidated balance sheets and a provision for credit losses in the consolidated statements of operations. Credit losses are accreted into earnings over time at the effective interest rate used to recognize interest income. Subsequent favorable or adverse changes in the amount of expected credit losses are recognized immediately in earnings. If the allowance for credit losses has been reduced to zero, we reflect the remaining favorable changes as a prospective adjustment to the effective interest rate of the investment. The allowance for credit losses is limited to the amount by which the investment’s amortized cost exceeds fair value. When the allowance for credit losses is limited, the effective interest rate used to recognize interest income and accrete credit losses is prospectively adjusted. We do not record an allowance for credit losses when an investment’s fair value exceeds its amortized cost. Recoveries of amounts previously written off relating to improvements in cash flows are recognized in earnings when received. We record provisions for credit losses, reductions in provisions for credit losses, accretion of credit losses, and recoveries of amounts previously written off within (increase) decrease in provision for credit losses in our consolidated statements of operations. When we determine that we intend to sell, or more likely than not will be required to sell, an available-for-sale security in an unrealized loss position before we recover its amortized cost, we write off any allowance for credit losses and write down the investment’s amortized cost to its fair value. We record the write off of the allowance for credit losses within (increase) decrease in provision for credit losses on our consolidated statements of operations and write down of the available-for-sale security within gain (loss) on investments, net in our consolidated statements of operations. We present accrued interest receivable separately from our investment portfolio on our consolidated balance sheets. We do not estimate an allowance for credit losses on accrued interest receivable because we write off accrued interest receivable as a reduction to interest income if it is not received when due. U.S. Treasury Securities
Commercial Loans Held-For-Investment	Commercial Loan Held-For-Investment We reported our commercial loan investment at fair value as described in the Fair Value Measurements section of this Note 2 to the consolidated financial statements. We recorded changes in fair value within gain (loss) on investments, net in our consolidated statements of operations.
Interest Income Recognition	Interest Income Recognition Mortgage-Backed Securities Interest income on MBS is accrued based on the outstanding principal or notional balance of the securities and their contractual terms. Premiums or discounts are amortized or accreted into interest income over the life of the investment using the effective interest method. Interest income on our MBS where we may not recover substantially all of our initial investment is based on estimated future cash flows. We estimate future expected cash flows at the time of purchase and determine the effective interest rate based on these estimated cash flows and our purchase price. Over the life of the investments, we update these estimated future cash flows and compute a revised yield based on the current amortized cost of the investment, unless those changes are reflected in an allowance for credit losses. In situations where an allowance for credit losses is limited by the fair value of the investment, we compute the yield as the rate that equates expected future cash flows to the current fair value of the investment. In estimating these future cash flows, there are a number of assumptions that are subject to uncertainties and contingencies, including but not limited to the rate and timing of principal payments (prepayments, repurchases, defaults and liquidations), the pass through or coupon rate, and interest rate fluctuations. These uncertainties and contingencies are difficult to predict and are subject to future events that may impact our estimate and our interest income. Changes in our original or most recent cash flow projections may result in a prospective change in interest income recognized on these securities, or the amortized cost of these securities, including write-offs of amortized cost when certain amounts are deemed uncollectible. For non-Agency RMBS not of high credit quality, when actual cash flows vary from expected cash flows, the difference is recorded as an adjustment to the amortized cost of the security, unless those changes are reflected in an allowance for credit losses, and the security's yield is revised prospectively. For Agency RMBS and Agency CMBS that cannot be prepaid in such a way that we would not recover substantially all of our initial investment, interest income recognition is based on contractual cash flows. We do not estimate prepayments in applying the effective interest method. Credit Risk Transfer Securities Interest income on GSE CRTs purchased before August 24, 2015 was accrued based on the coupon rate of the debt host contract which reflected the credit risk of GSE unsecured senior debt with a similar maturity. Premiums or discounts associated with the purchase of GSE CRTs were amortized or accreted into interest income over the life of the debt host contract using the effective interest method. The difference between the coupon rate on the hybrid instrument and the coupon rate on the debt host contract was considered premium income associated with the embedded derivative and was recorded in realized and unrealized credit derivative income (loss), net in our consolidated statements of operations. Interest income on GSE CRTs purchased on or after August 24, 2015 was based on estimated future cash flows. Commercial and Other Loans We recognize interest income from commercial and other loans when earned and deemed collectible, or until a loan becomes past due based on the terms of the loan agreement. Any related origination fees or costs on commercial and other loans for which we have elected the fair value option are recognized immediately in earnings. Interest received after a loan becomes past due or impaired is used to reduce the outstanding loan principal balance. When a delinquent loan previously placed on nonaccrual status has cured, meaning all delinquent principal and interest have been remitted by the borrower, the loan is placed back on accrual status. Alternately, loans that have been individually impaired may be placed back on accrual status if restructured and after the loan is considered re-performing. A restructured loan is considered re-performing when the loan has been current for at least 12 months.
Cash and Cash Equivalents	Cash and Cash EquivalentsWe consider all highly liquid investments that have original or remaining maturity dates of three months or less when purchased to be cash equivalents.
Restricted Cash	Restricted CashRestricted cash represents cash posted with counterparties as collateral for various derivative instruments. Cash posted with counterparties as collateral is not available for general corporate purposes.
Due from Counterparties/Collateral Held Payable	Due from Counterparties / Collateral Held PayableDue from counterparties represents cash posted with our counterparties as collateral for our derivatives and repurchase agreements. Collateral held payable represents cash posted with us by counterparties as collateral under our derivatives and repurchase agreements. If we receive collateral other than cash from our counterparties, such assets are not included in our consolidated balance sheets. If we either sell such assets or pledge the assets as collateral under a repurchase agreement, the cash received and the corresponding liability is reflected on the consolidated balance sheets
Investment Related Receivable / Investment Related Payable	Investment Related Receivable / Investment Related Payable Investment related receivable consists of receivables for mortgage-backed securities that we have sold but have not settled with the buyer and accrued interest and principal paydowns on mortgage-backed securities. Investment related payable consists of liabilities for mortgage-backed securities that we have purchased but have not settled with the seller.
Investments in Unconsolidated Ventures	Investments in Unconsolidated VenturesOur non-controlling investments in unconsolidated ventures are included in other assets in our consolidated balance sheets and are accounted for under the equity method. Capital contributions, distributions, profits and losses of the entities are allocated in accordance with the terms of the entities’ operating agreements. Such allocations may differ from the stated percentage interests, if any, as a result of preferred returns and allocation formulas as described in the entities' operating agreements.
Repurchase Agreements	Repurchase Agreements We have financed our purchases of mortgage-backed and credit risk transfer securities primarily through the use of repurchase agreements. Repurchase agreements are treated as collateralized financing transactions and are carried at their contractual amounts, including accrued interest, as specified in the respective agreements. We record the mortgage-backed securities and the related repurchase agreement financing on a gross basis in our consolidated balance sheets, and the corresponding interest income and interest expense on a gross basis in our consolidated statements of operations.
Secured Loans	Secured Loans Our wholly-owned subsidiary, IAS Services LLC, was a member of the Federal Home Loan Bank of Indianapolis (“FHLBI”). As a member of the FHLBI, IAS Services LLC borrowed funds from the FHLBI in the form of secured advances. FHLBI advances were treated as secured financing transactions and carried at their contractual amounts. During the year ended December 31, 2020, we fully repaid our outstanding secured loans from the FHLBI and terminated our membership. IAS Services LLC was dissolved in December 2020.
Dividends Payable	Dividends PayableDividends payable represent dividends declared at the balance sheet date that are payable to common stockholders and preferred stockholders.
Earnings (Loss) per Share	Earnings (Loss) per Share We calculate basic earnings (loss) per share by dividing net income (loss) attributable to common stockholders for the period by the weighted-average number of shares of our common stock outstanding for that period. Diluted earnings per share takes into account the effect of dilutive instruments, such as unvested restricted stock awards, and uses the average share price for the period in determining the number of incremental shares that are to be added to the weighted-average number of shares outstanding.
Share-Based Compensation	Share-Based Compensation Under the terms of our amended and restated 2009 Equity Incentive Plan (the “Incentive Plan”), our independent directors are eligible to receive stock awards as part of their compensation for serving as directors, In addition, we may compensate the officers and employees of our Manager and its affiliates under the Incentive Plan under the terms of our management agreement.
Underwriting Commissions and Offering Costs	Underwriting Commissions and Offering Costs Underwriting commissions and direct costs incurred in connection with our common and preferred stock offerings are recorded as a reduction of additional paid in capital and preferred stock, respectively.
Comprehensive Income	Comprehensive Income Our comprehensive income consists of net income, as presented in the consolidated statements of operations, adjusted for unrealized gains and losses on MBS purchased before September 1, 2016 and the debt host contract associated with GSE CRTs purchased before August 24, 2015; reclassification of unrealized losses on available-for-sale securities to (increase) decrease in provision for credit losses; reclassification of amortization of net deferred gains and losses on de-designated interest rate swaps to repurchase agreements interest expense and currency translation adjustments on an investment in an unconsolidated venture. Unrealized gains and losses on our MBS purchased before September 1, 2016 and the debt host contract associated with GSE CRTs purchased before August 24, 2015 are reclassified into net income upon their sale.
Accounting for Derivative Financial Instruments	Accounting for Derivative Financial Instruments We record all derivatives on our consolidated balance sheets at fair value. At the inception of a derivative contract, we determine whether the instrument will be part of a qualifying hedge accounting relationship or whether we will account for the contract as a trading instrument. We have elected not to apply hedge accounting to all new derivative contracts entered into after January 1, 2014. Changes in the fair value of our derivatives are recorded in gain (loss) on derivative instruments, net in our consolidated statements of operations. Net interest paid or received under our interest rate swaps is also recognized in gain (loss) on derivative instruments, net in our consolidated statements of operations. Before 2014, we applied hedge accounting to our interest rate swap agreements. Effective December 31, 2013, we voluntarily discontinued hedge accounting for our interest rate swap agreements by de-designating the interest rate swaps as cash flow hedges. As long as we expect the forecasted transactions that were being hedged (i.e., rollovers of our repurchase agreement borrowings) to still occur, the balance recorded in accumulated other comprehensive income (loss) (“AOCI”) from the interest rate swap activity through December 31, 2013 will remain in AOCI and be recognized in our consolidated statements of operations as interest expense over the remaining term of the interest rate swaps. Prior to December 31, 2020, we were a party to hybrid financial instruments that contained embedded derivative instruments and for which we did not elect the fair value option. We assessed at inception whether the economic characteristics of the embedded derivative instruments were clearly and closely related to the economic characteristics of the remaining component of the financial instrument (i.e., the debt host contract), whether the financial instrument was remeasured to fair value through earnings and whether a separate instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. When it was determined that (1) the embedded instrument possessed economic characteristics that were not clearly and closely related to the economic characteristics of the debt host contract, (2) the financial instrument was not remeasured to fair value through earnings and (3) a separate instrument with the same terms would qualify as a derivative instrument, the embedded instrument qualified as an embedded derivative that was separated from the debt host contract. The embedded derivative was recorded at fair value, and changes in fair value were recorded in realized and unrealized credit derivative income (loss), net in our consolidated statements of operations. We evaluate the terms and conditions of our holdings of swaptions, currency forward contracts and TBAs to determine if an instrument has the characteristics of an investment or should be considered a derivative under U.S. GAAP. Accordingly, swaptions, currency forward contracts and TBAs having the characteristics of derivatives are accounted for at fair value with such changes recognized in gain (loss) on derivative instruments, net in the consolidated statements of operations. The fair value of these swaptions, currency forward contracts and TBAs is included in derivative assets or derivative liabilities on the consolidated balance sheets.
Income Taxes	Income Taxes We elected to be taxed as a REIT commencing with our taxable year ended December 31, 2009. Accordingly, we will generally not be subject to U.S. federal and applicable state and local corporate income tax to the extent that we make qualifying distributions to our stockholders, and provided we satisfy on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution and stock ownership tests. If we fail to qualify as a REIT and do not qualify for certain statutory relief provisions, we will be subject to U.S. federal, state and local income taxes and may be precluded from qualifying as a REIT for the four taxable years following the year in which we lost our REIT qualification. Accordingly, our failure to qualify as a REIT could have a material adverse impact on our results of operations and amounts available for distribution to stockholders. Our dividends paid deduction for qualifying dividends to our stockholders is computed using our REIT taxable income as opposed to net income reported on the consolidated financial statements. REIT taxable income will generally differ from net income because the determination of REIT taxable income is based on tax regulations and not financial accounting principles. We have elected to treat one of our subsidiaries as taxable REIT subsidiaries (“TRS”). In general, a TRS may hold assets and engage in activities that we cannot hold or engage in directly and generally may engage in any real estate or non-real estate-related business. A TRS is subject to U.S. federal, state and local corporate income taxes. Our TRS did not generate material taxable income for the years ended December 31, 2022, 2021 and 2020. We do not have any accruals for uncertain tax positions. We would recognize interest and penalties related to uncertain tax positions, if any, as income tax expense, which would be included in general and administrative expenses.
