Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Investment Objective	Organization and Investment Objective Ellington Financial Inc., formerly known as Ellington Financial LLC, was originally formed as a Delaware limited liability company on July 9, 2007 and commenced operations on August 17, 2007. On February 28, 2019, Ellington Financial LLC filed a certificate of conversion with the Secretary of State of the State of Delaware (the "Secretary") to convert from a Delaware limited liability company to a Delaware corporation (the "Conversion") and change its name to Ellington Financial Inc. The Conversion became effective on March 1, 2019, and upon effectiveness, each of Ellington Financial LLC's existing common shares representing limited liability company interests, no par value, converted into one issued and outstanding, fully paid and nonassessable share of common stock, $0.001 par value per share, of Ellington Financial Inc. In connection with the Conversion, Ellington Financial Inc.'s Board of Directors (the "Board of Directors") approved Ellington Financial Inc.'s Certificate of Incorporation (which was also filed with the Secretary) and Bylaws. Ellington Financial Operating Partnership LLC (the "Operating Partnership"), a 99.0% owned consolidated subsidiary of Ellington Financial Inc., was formed as a Delaware limited liability company on December 14, 2012 and commenced operations on January 1, 2013. All of Ellington Financial Inc.'s operations and business activities are conducted through the Operating Partnership. Ellington Financial Inc., the Operating Partnership, and their consolidated subsidiaries are hereafter collectively referred to as the "Company." All intercompany accounts are eliminated in consolidation. The Company conducts its operations to qualify and be taxed as a real estate investment trust, or "REIT," under the Internal Revenue Code of 1986, as amended (the "Code"), and has elected to be taxed as a corporation effective January 1, 2019. In anticipation of the Company's intended election to be taxed as a REIT under the Code beginning with its 2019 taxable year (the "REIT Election"), the Company implemented an internal restructuring as of December 31, 2018. As part of this restructuring, the Company moved certain of its non-REIT-qualifying investments and financial derivatives to taxable REIT subsidiaries or, "TRSs," and disposed of certain of its investments in non-REIT-qualifying investments and financial derivatives. The Company invests in a diverse array of financial assets, including residential and commercial mortgage loans, residential mortgage-backed securities, or "RMBS," commercial mortgage-backed securities, or "CMBS," consumer loans and asset-backed securities, or "ABS," including ABS backed by consumer loans, collateralized loan obligations, or "CLOs," non-mortgage- and mortgage-related derivatives, equity investments in loan origination companies, and other strategic investments. Ellington Financial Management LLC (the "Manager") is an SEC-registered investment adviser that serves as the Manager to the Company pursuant to the terms of its Seventh Amended and Restated Management Agreement (the "Management Agreement"), which was approved by the Board of Directors effective March 13, 2018. The Manager is an affiliate of Ellington Management Group, L.L.C. ("Ellington"), an investment management firm that is registered as both an investment adviser and a commodity pool operator. In accordance with the terms of the Management Agreement, the Manager implements the investment strategy and manages the business and operations on a day-to-day basis for the Company and performs certain services for the Company, subject to oversight by the Board of Directors.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies (A) Basis of Presentation : The Company's unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America, or "U.S. GAAP," and Regulation S-X. The condensed consolidated financial statements include the accounts of the Company, the Operating Partnership, its subsidiaries, and variable interest entities, or "VIEs," for which the Company is deemed to be the primary beneficiary. All intercompany balances and transactions have been eliminated. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and those differences could be material. In management's opinion, all material adjustments considered necessary for a fair statement of the Company's consolidated financial statements have been included and are only of a normal recurring nature. Interim results are not necessarily indicative of the results that may be expected for the entire fiscal year. The information included in the condensed consolidated financial statements and notes thereto should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2021. (B) Valuation : The Company applies ASC 820-10, Fair Value Measurement ("ASC 820") to its holdings of financial instruments. ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: • Level 1—inputs to the valuation methodology are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Currently, the types of financial instruments the Company generally includes in this category are listed equities and exchange-traded derivatives; • Level 2—inputs to the valuation methodology other than quoted prices included in Level 1 are observable for the asset or liability, either directly or indirectly. Currently, the types of financial instruments that the Company generally includes in this category are RMBS, for which the principal and interest payments are guaranteed by a U.S. government agency or a U.S. government-sponsored entity, or "Agency RMBS," U.S. Treasury securities and sovereign debt, certain non-Agency RMBS, CMBS, CLOs, corporate debt, and actively traded derivatives such as interest rate swaps, foreign currency forwards, and other over-the-counter derivatives; and • Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement. The types of financial instruments that the Company generally includes in this category are certain RMBS, CMBS, CLOs, ABS, credit default swaps, or "CDS," on individual ABS, and total return swaps on distressed corporate debt, in each case where there is less price transparency. Also included in this category are residential and commercial mortgage loans, consumer loans, and private corporate debt and equity investments. For certain financial instruments, the various inputs that management uses to measure fair value may fall into different levels of the fair value hierarchy. For each such financial instrument, the determination of which category within the fair value hierarchy is appropriate is based on the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the various inputs that management uses to measure fair value, with the highest priority given to inputs that are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets (Level 1), and the lowest priority given to inputs that are unobservable and significant to the fair value measurement (Level 3). The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. The Company may use valuation techniques consistent with the market and income approaches to measure the fair value of its financial instruments. The market approach uses third-party valuations and information obtained from market transactions involving identical or similar financial instruments. The income approach uses projections of the future economic benefit of an instrument to determine its fair value, such as in the discounted cash flow methodology. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risk associated with investing in these financial instruments. The leveling of each financial instrument is reassessed at the end of each period. Transfers between levels of the fair value hierarchy are assumed to occur at the end of the reporting period. Summary Valuation Techniques For financial instruments that are traded in an "active market," the best measure of fair value is the quoted market price. However, many of the Company's financial instruments are not traded in an active market. Therefore, management generally uses third-party valuations when available. If third-party valuations are not available, management uses other valuation techniques, such as the discounted cash flow methodology. The following are summary descriptions, for various categories of financial instruments, of the valuation methodologies management uses in determining fair value of the Company's financial instruments in such categories. Management utilizes such methodologies to assign a fair value (the estimated price that, in an orderly transaction at the valuation date, would be received to sell an asset, or paid to transfer a liability, as the case may be) to each such financial instrument. For mortgage-backed securities, or "MBS," forward settling to-be-announced mortgage-backed-securities, or "TBAs," CLOs, and corporate debt and equity, management seeks to obtain at least one third-party valuation, and often obtains multiple valuations when available. Management has been able to obtain third-party valuations on the vast majority of these instruments and expects to continue to solicit third-party valuations in the future. Management generally values each financial instrument at the average of third-party valuations received and not rejected as described below. Third-party valuations are not binding, management may adjust the valuations it receives (e.g., downward adjustments for odd lots), and management may challenge or reject a valuation when, based on its validation criteria, management determines that such valuation is unreasonable or erroneous. Furthermore, based on its validation criteria, management may determine that the average of the third-party valuations received for a given financial instrument does not result in what management believes to be the fair value of such instrument, and in such circumstances management may override this average with its own good faith valuation. The validation criteria may take into account output from management's own models, recent trading activity in the same or similar instruments, and valuations received from third parties. The use of proprietary models requires the use of a significant amount of judgment and the application of various assumptions including, but not limited to, assumptions concerning future prepayment rates and default rates. Given their relatively high level of price transparency, Agency RMBS pass-throughs are typically classified as Level 2. Non-Agency RMBS, CMBS, Agency interest only and inverse interest only RMBS, CLOs, and corporate bonds are generally classified as either Level 2 or Level 3 based on analysis of available market data and/or third-party valuations. The Company's investments in distressed corporate debt can be in the form of loans as well as total return swaps on loans. These investments, as well as related non-listed equity investments, are generally designated as Level 3 assets. Valuations for total return swaps are typically based on prices of the underlying loans received from third-party pricing services. Private equity investments are generally classified as Level 3. Furthermore, the methodology used by the third-party valuation providers is reviewed at least annually by management, so as to ascertain whether such providers are utilizing observable market data to determine the valuations that they provide. For residential and commercial mortgage loans, and consumer loans, management determines fair value by taking into account both external pricing data, which includes third-party valuations, and internal pricing models. Management has obtained third-party valuations on the majority of these investments and expects to continue to solicit third-party valuations in the future. In determining fair value for non-performing mortgage loans, management evaluates third-party valuations, if applicable, as well as management's estimates of the value of the underlying real estate, using information including general economic data, broker price opinions, or "BPOs," recent sales, property appraisals, and bids. In determining fair value for performing mortgage loans and consumer loans, management evaluates third-party valuations, if applicable, as well as discounted cash flows of the loans based on market assumptions. Cash flow assumptions typically include projected default and prepayment rates and loss severities, and may include adjustments based on appraisals and BPOs. Mortgage and consumer loans are classified as Level 3. The Company has securitized certain mortgage loans that are not deemed "qualified mortgage," or "QM," loans under the rules of the Consumer Financial Protection Bureau, or "non-QM loans." The Company's securitized non-QM loans are held as part of a collateralized financing entity, or "CFE." A CFE is a VIE that holds financial assets, issues beneficial interests in those assets, and has no more than nominal equity, and for which the issued beneficial interests have contractual recourse only to the related assets of the CFE. ASC 810, Consolidation ("ASC 810") allows the Company to elect to measure both the financial assets and financial liabilities of the CFE using the more observable of the fair value of the financial assets and the fair value of the financial liabilities of the CFE. The Company has elected the fair value option, or "FVO," for initial and subsequent recognition of the debt issued by its consolidated securitization trusts and has determined that each consolidated securitization trust meets the definition of a CFE; see Note 10 " Securitization Transactions — Residential Mortgage Loan Securitizations " for further discussion on the Company's securitization trusts. The Company has determined the inputs to the fair value measurement of the financial liabilities of each of its CFEs to be more observable than those of the financial assets and, as a result, has used the fair value of the financial liabilities of each of the CFEs to measure the fair value of the financial assets of each of the CFEs. The fair value of the debt issued by each CFE is typically valued using both external pricing data, which includes third-party valuations, and internal pricing models. The securitized non-QM loans, which are assets of the CFEs, are included in Loans, at fair value, on the Company's Consolidated Balance Sheet. The debt issued by the CFEs is included in Other secured borrowings, at fair value, on the Company's Consolidated Balance Sheet. Unrealized gains (losses) from changes in fair value of Other secured borrowings, at fair value, are included in Unrealized gains (losses) on other secured borrowings, at fair value, net, on the Company's Consolidated Statement of Operations. The securitized non-QM loans and the debt issued by the Company's CFEs are both classified as Level 3. For financial derivatives with greater price transparency, such as CDS on asset-backed indices, CDS on corporate indices, certain options on the foregoing, and total return swaps on publicly traded equities or indices, market-standard pricing sources are used to obtain valuations; these financial derivatives are generally classified as Level 2. Interest rate swaps, swaptions, and foreign currency forwards are typically valued based on internal models that use observable market data, including applicable interest rates and foreign currency rates in effect as of the measurement date; the model-generated valuations are then typically compared to counterparty valuations for reasonableness. These financial derivatives are also generally classified as Level 2. Financial derivatives with less price transparency, such as CDS on individual ABS, are generally valued based on internal models, and are classified as Level 3. In the case of CDS on individual ABS, the valuation process typically starts with an estimation of the value of the underlying ABS. In valuing its financial derivatives, the Company also considers the creditworthiness of both the Company and its counterparties, along with collateral provisions contained in each financial derivative agreement. Investments in private operating entities, such as loan originators, are valued based on available metrics, such as relevant market multiples and comparable company valuations, company specific-financial data including actual and projected results, and independent third party valuation estimates. These investments are classified as Level 3. The Company's repurchase and reverse repurchase agreements are carried at cost, which approximates fair value. Repurchase and reverse repurchase agreements are classified as Level 2, based on the adequacy of the collateral and their short term nature. The Company's valuation process, including the application of validation criteria, is directed by the Manager's Valuation Committee (the "Valuation Committee"), and overseen by the Company's audit committee. The Valuation Committee includes senior level executives from various departments within the Manager, and each quarter, the Valuation Committee reviews and approves the valuations of the Company's financial instruments. The valuation process also includes a monthly review by the Company's third-party administrator. The goal of this review is to replicate various aspects of the Company's valuation process based on the Company's documented procedures. Because of the inherent uncertainty of valuation, the estimated fair value of the Company's financial instruments may differ significantly from the values that would have been used had a ready market for the financial instruments existed, and the differences could be material to the Company's consolidated financial statements. (C) Accounting for Securities : Purchases and sales of investments in securities are generally recorded on trade date, and realized and unrealized gains and losses are calculated based on identified cost. Investments in securities are recorded in accordance with ASC 320, Investments—Debt and Equity Securities ("ASC 320") or ASC 325-40, Beneficial Interests in Securitized Financial Assets ("ASC 325-40"). The Company generally classifies its securities as available-for-sale. The Company has chosen to elect the FVO pursuant to ASC 825, Financial Instruments ("ASC 825") for its investments in securities. Electing the FVO allows the Company to record changes in fair value in the Consolidated Statement of Operations, as a component of Unrealized gains (losses) on securities and loans, net, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all investment activities will be recorded in a similar manner. Many of the Company's investments in securities, such as MBS and CLOs, are issued by entities that are deemed to be VIEs. For the majority of such investments, the Company has determined it is not the primary beneficiary of such VIEs and therefore has not consolidated such VIEs. The Company's maximum risk of loss in these unconsolidated VIEs is generally limited to the fair value of the Company's investment in the VIE. The Company evaluates its investments in interest only securities to determine whether they meet the requirements for classification as financial derivatives under ASC 815, Derivatives and Hedging ("ASC 815"). For interest only securities, where the holder is entitled only to a portion of the interest payments made on the mortgages underlying certain MBS, and inverse interest only securities, which are interest only securities whose coupon has an inverse relationship to its benchmark rate, such as LIBOR, the Company has determined that such investments do not meet the requirements for treatment as financial derivatives and are classified as securities. The Company applies the principles of ASU 2016-13, Financial Instruments—Credit Losses ("ASU 2016-13") and evaluates the cost basis of its investments in securities on at least a quarterly basis, under ASC 326-30, Financial Instruments—Credit Losses: Available-for-Sale Debt Securities ("ASC 326-30"). When the fair value of a security is less than its amortized cost basis as of the balance sheet date, the security's cost basis is considered impaired. The Company must evaluate the decline in the fair value of the impaired security and determine whether such decline resulted from a credit loss or non-credit related factors. In its assessment of whether a credit loss exists, the Company compares the present value of estimated future cash flows of the impaired security with the amortized cost basis of such security. The estimated future cash flows reflect those that a "market participant" would use and typically include assumptions related to fluctuations in interest rates, prepayment speeds, default rates, collateral performance, and the timing and amount of projected credit losses, as well incorporating observations of current market developments and events. Cash flows are discounted at an interest rate equal to the current yield used to accrete interest income. If the present value of estimated future cash flows is less than the amortized cost basis of the security, an expected credit loss exists and is included in Unrealized gains (losses) on securities and loans, net, on the Consolidated Statement of Operations. If it is determined as of the financial reporting date that all or a portion of a security's cost basis is not collectible, then the Company will recognize a realized loss to the extent of the adjustment to the security's cost basis. This adjustment to the amortized cost basis of the security is reflected in Net realized gains (losses) on securities and loans, net, on the Consolidated Statement of Operations. (D) Accounting for Loans : The Company's loan portfolio primarily consists of residential mortgage, commercial mortgage, and consumer loans. The Company's loans are accounted for under ASC 310-10, Receivables , and are classified as held-for-investment when the Company has the intent and ability to hold such loans for the foreseeable future or to maturity/payoff. When the Company has the intent to sell loans, such loans will be classified as held-for-sale. Mortgage loans held-for-sale are accounted for under ASC 948-310, Financial services—mortgage banking. The Company may aggregate its loans into pools based on common risk characteristics at purchase. The Company has chosen to elect the FVO pursuant to ASC 825 for its loan portfolios. Loans are recorded at fair value on the Consolidated Balance Sheet and changes in fair value are recorded in earnings on the Consolidated Statement of Operations as a component of Unrealized gains (losses) on securities and loans, net. The Company generates income from fees on certain loans, generally commercial mortgage loans, that it originates and holds for investment, including origination and exit fees. Such fee income is recorded when earned and included in Other, net on the Consolidated Statement of Operations. Transfers between held-for-investment and held-for-sale occur once the Company's intent to sell the loans changes. For residential and commercial mortgage loans, the Company generally accrues interest payments. Such loans are typically moved to non-accrual status if the loan becomes 90 days or more delinquent. The Company does not accrue interest payments on its consumer loans; interest payments are recorded upon receipt. Once consumer loans are more than 120 days past due, the Company will generally charge off such loans. The Company evaluates its charged-off loans and determines collectibility, if any, on such loans. The Company evaluates the collectibility of both interest and principal on each of its loan investments and whether the cost basis of the loan is impaired. A loan's cost basis is impaired when, based on current information and market developments, it is probable that the Company will be unable to collect all amounts due according to the existing contractual terms. When a loan's cost basis is impaired, the Company does not record an allowance for loan loss as it elected the FVO on all of its loan investments. Consistent with the Company's application of the principles of ASU 2016-13, in its assessment of whether a credit loss exists, the Company compares the present value of the amount expected to be collected on the impaired loan with the amortized cost basis of such loan. If the present value of the amount expected to be collected on the impaired loan is less than the amortized cost basis of such loan, an expected credit loss exists and is included in Unrealized gains (losses) on securities and loans, net, on the Consolidated Statement of Operations. If it is determined as of the financial reporting date that all or a portion of a loan's cost basis is not collectible, then the Company will recognize a realized loss to the extent of the adjustment to the loan's cost basis. This adjustment to the amortized cost basis of the loan is reflected in Realized gains (losses) on securities and loans, net, on the Consolidated Statement of Operations. (E) Interest Income : The Company amortizes premiums and accretes discounts on its debt securities. Coupon interest income on fixed-income investments is generally accrued based on the outstanding principal balance or notional value and the current coupon rate. For debt securities that are deemed to be of high credit quality at the time of purchase (generally Agency RMBS, exclusive of interest only securities), premiums and discounts are amortized/accreted into interest income over the life of such securities using the effective interest method. For such securities whose cash flows vary depending on prepayments, an effective yield retroactive to the time of purchase is periodically recomputed based on actual prepayments and changes in projected prepayment activity, and a catch-up adjustment, or "Catch-up Premium Amortization Adjustment," is made to amortization to reflect the cumulative impact of the change in effective yield. For debt securities (generally non-Agency RMBS, CMBS, ABS, CLOs, and interest only securities) that are deemed not to be of high credit quality at the time of purchase, interest income is recognized based on the effective interest method. For purposes of estimating future expected cash flows, management uses assumptions including, but not limited to, assumptions for future prepayment rates, default rates, and loss severities (each of which may in turn incorporate various macro-economic assumptions, such as future housing prices, GDP growth rates, and unemployment rates). These assumptions are re-evaluated not less than quarterly. Changes in projected cash flows may result in prospective changes in the yield/interest income recognized on such securities based on the updated expected future cash flows. For each loan purchased with the expectation that both interest and principal will be paid in full, the Company generally amortizes or accretes any premium or discount over the life of the loan utilizing the effective interest method. However, based on current information and market developments, the Company re-assesses the collectibility of interest and principal, and generally designates a loan as in non-accrual status either when any payments have become 90 or more days past due, or when, in the opinion of management, it is probable that the Company will be unable to collect either interest or principal in full. Once a loan is designated as in non-accrual status, as long as principal is still expected to be collectible in full, interest payments are recorded as interest income only when received (i.e., under the cash basis method); accruals of interest income are only resumed when the loan becomes contractually current and performance is demonstrated to be resumed. However, if principal is not expected to be collectible in full, the cost recovery method is used (i.e., no interest income is recognized, and all payments received—whether contractually interest or principal—are applied to cost). Certain of the Company's debt securities and loans, at the date of acquisition, have experienced or are expected to experience more-than-insignificant deterioration in credit quality since origination. Consistent with the Company's application of the principles of ASU 2016-13, if at the date of acquisition for a particular asset the Company projects a significant difference between contractual cash flows and expected cash flows, it establishes an initial estimate for credit losses as an upward adjustment to the acquisition cost of the asset for the purpose of calculating interest income using the effective yield method. In estimating future cash flows on the Company's debt securities, there are a number of assumptions that are subject to significant uncertainties and contingencies, including, in the case of MBS, assumptions relating to prepayment rates, default rates, loan loss severities, and loan repurchases. These estimates require the use of a significant amount of judgment. (F) Investments in unconsolidated entities : The Company has made and may in the future make non-controlling equity investments in various entities, such as loan originators. Such investments are generally in the form of preferred and/or common equity, or membership interests. In certain cases, the Company can exercise significant influence over the entity (e.g. by having representation on the entity's board of directors) but the requirements for consolidation under ASC 810 are not met; in such cases the Company is required to account for such equity investments under ASC 323-10, Investments—Equity Method and Joint Ventures ("ASC 323-10"). The Company has chosen to elect the FVO pursuant to ASC 825 for its investments in unconsolidated entities, which, in management's view, more appropriately reflects the results of operations for a particular reporting period, as all investment activities will be recorded in a similar manner. The period change in fair value of the Company's investments in unconsolidated entities is recorded on the Consolidated Statement of Operations in Earnings (losses) from investments in unconsolidated entities. (G) Real Estate Owned "REO" : When the Company obtains possession of real property in connection with a foreclosure or similar action, the Company de-recognizes the associated mortgage loan according to ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure ("ASU 2014-04"). Under the provisions of ASU 2014-04, the Company is deemed to have received physical possession of real estate property collateralizing a mortgage loan when it obtains legal title to the property upon completion of a foreclosure or when the borrower conveys all interest in the property to it through a deed in lieu of foreclosure or similar legal agreement. The Company's initial cost basis in REO is equal to the fair value of the real estate associated with the foreclosed mortgage loan, less expected costs to sell. REO valuations are reflected at the lower of cost or fair value. The fair value of such REO is typically based on management's estimates which generally use information including general economic data, BPOs, recent sales, property appraisals, and bids, and takes into account the expected costs to sell the property. REO recorded at fair value on a non-recurring basis are classified as Level 3. (H) Securities Sold Short : The Company may purchase or engage in short sales of U.S. Treasury securities and sovereign debt to mitigate the potential impact of changes in interest rates and/or foreign exchange rates on the performance of its portfolio. When the Company sells securities short, it typically satisfies its security delivery settlement obligation by borrowing or purchasing the security sold short from the same or a different counterparty. When borrowing a security sold short from a counterparty, the Company generally is required to deliver cash or securities to such counterparty as collateral for the Company's obligation to return the borrowed security. The Company has chosen to elect the FVO pursuant to ASC 825 for its securities sold short. Electing the FVO allows the Company to record changes in fair value in the Consolidated Statement of Operations, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all securities activities will be recorded in a similar manner. As such, securities sold short are recorded at fair value on the Consolidated Balance Sheet and the period change in fair value is recorded in current period earnings on the Consolidated Statement of Operations as a component of Unrealized gains (losses) on securities and loans, net. A realized gain or loss will be recognized upon the termination of a short sale if the market price is less or greater than the original sale price. Such realized gain or loss is recorded on the Company's Consolidated Statement of Operations in Realized gains (losses) on securities and loans, net. (I) Financial Derivatives : The Company enters into various types of financial derivatives subject to its investment guidelines, which include restrictions associated with maintaining qualification as a REIT. The Company's financial derivatives are predominantly subject to bilateral master trade agreements or clearing in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the "Dodd-Frank Act." The Company may be required to deliver or receive cash or securities as collateral upon entering into derivative transactions. In addition, changes in the value of derivative transactions may require the Company or the counterparty to post or receive additional collateral. In the case of cleared derivatives, the clearinghouse becomes the Company's counterparty and a futures commission merchant acts as an intermediary between the Company and the clearinghouse with respect to all facets of the related transaction, including the posting and receipt of required collateral. Cash collateral received by the Company is included in Due to brokers, on the Consolidated Balance Sheet. Conversely, cash collateral posted by the Company is included in Due from brokers, on the Consolidated Balance Sheet. The types of derivatives primarily utilized by the Company are swaps, TBAs, futures, options, and forwards. Swaps : The Company may enter into various types of swaps, including interest rate swaps, credit default swaps, and total return swaps. The primary risk associated with the Company's interest rate swap activity is interest rate risk. The primary risk associated with the Company's credit default swaps and total return swaps is credit risk. The Company is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Primarily to help mitigate interest rate risk, the Company enters into interest rate swaps. Interest rate swaps are contractual agreements whereby one party pays a floating interest rate on a notional principal amount and receives a fixed-rate payment on the same notional principal, or vice versa, for a fixed period of time. Interest rate swaps change in value with movements in interest rates. The Company also enters into interest rate swaps whereby the Company pays one floating rate and receives a different floating rate, or "basis swaps."

Third-party non-binding valuations are validated by comparing such valuations to internally generated prices based on the Company's models and, when available, to recent trading activity in the same or similar instruments. For those instruments valued using discounted and net discounted cash flows, collateral prepayments, losses, recoveries, and scheduled amortization are projected over the remaining life of the collateral and expressed as a percentage of the collateral's current principal balance. Averages are weighted based on the fair value of the related instrument. In the case of credit default swaps on asset-backed securities, averages are weighted based on each instrument's bond equivalent value. Bond equivalent value represents the investment amount of a corresponding position in the reference obligation, calculated as the difference between the outstanding principal balance of the underlying reference obligation and the fair value, inclusive of accrued interest, of the derivative contract. For those assets valued using the LIBOR Option Adjusted Spread ("LIBOR OAS") valuation methodology, cash flows are projected using the Company's models over multiple interest rate scenarios, and these projected cash flows are then discounted using the LIBOR rates implied by each interest rate scenario. The LIBOR OAS of an asset is then computed as the unique constant yield spread that, when added to all LIBOR rates in each interest rate scenario generated by the model, will equate (a) the expected present value of the projected asset cash flows over all model scenarios to (b) the actual current market price of the asset. LIBOR OAS is therefore model-dependent. Generally speaking, LIBOR OAS measures the additional yield spread over LIBOR that an asset provides at its current market price after taking into account any interest rate options embedded in the asset. The Company considers the expected timeline to resolution in the determination of fair value for its non-performing commercial and residential mortgage loans. Material changes in any of the inputs above in isolation could result in a significant change to reported fair value measurements. Additionally, fair value measurements are impacted by the interrelationships of these inputs. For example, for instruments subject to prepayments and credit losses, such as non-Agency RMBS and consumer loans and ABS backed by consumer loans, a higher expectation of collateral prepayments will generally be accompanied by a lower expectation of collateral losses. Conversely, higher losses will generally be accompanied by lower prepayments. Because the Company's credit default swaps on asset-backed security holdings represent credit default swap contracts whereby the Company has purchased credit protection, such credit default swaps on asset-backed securities generally have the directionally opposite sensitivity to prepayments, losses, and recoveries as compared to the Company's long securities holdings. Prepayments do not represent a significant input for the Company's commercial mortgage-backed securities and commercial mortgage loans. Losses and recoveries do not represent a significant input for the Company's Agency RMBS interest only securities, given the guarantee of the issuing government agency or government-sponsored enterprise.

Investment in Loans	Investment in LoansThe Company invests in various types of loans, such as residential mortgage, commercial mortgage, consumer, and corporate loans. As discussed in Note 2, the Company has elected the FVO for its investments in loans. The following table is a summary of the Company's investments in loans as of March 31, 2022 and December 31, 2021: As of (In thousands) March 31, 2022 December 31, 2021 Loan Type Unpaid Principal Balance Fair Unpaid Principal Balance Fair Residential mortgage loans $ 2,452,210 $ 2,433,007 $ 1,969,874 $ 2,016,228 Commercial mortgage loans 430,031 429,954 326,438 326,197 Consumer loans 10,865 9,878 59,881 62,365 Corporate loans 11,788 11,788 10,531 10,531 Total $ 2,904,894 $ 2,884,627 $ 2,366,724 $ 2,415,321 The Company is subject to credit risk in connection with its investments in loans. The two primary components of credit risk are default risk, which is the risk that a borrower fails to make scheduled principal and interest payments, and severity risk, which is the risk of loss upon a borrower default on a mortgage loan or other secured or unsecured loan. Severity risk includes the risk of loss of value of the property or other asset, if any, securing the loan, as well as the risk of loss associated with taking over the property or other asset, if any, including foreclosure costs. Credit risk in our loan portfolio can be amplified by exogenous shocks impacting our borrowers such as man-made or natural disasters, such as the COVID-19 pandemic.

Pursuant to these TBA transactions, the Company agrees to purchase or sell, for future delivery, Agency RMBS with certain principal and interest terms and certain types of underlying collateral, but the particular Agency RMBS to be delivered is not identified until shortly before the TBA settlement date. TBAs are generally liquid, have quoted market prices, and represent the most actively traded class of MBS. The Company uses TBAs to mitigate interest rate risk, usually by taking short positions. The Company also invests in TBAs as a means of acquiring additional exposure to Agency RMBS, or for investment purposes, including holding long positions. The Company does not usually take delivery of TBAs; rather, it settles the associated receivable and payable with its trading counterparties on a net basis. Transactions with the same counterparty for the same TBA that result in a reduction of the position are treated as extinguished.

The table below details the average notional values of the Company's financial derivatives, using absolute value of month end notional values, for the three-month period ended March 31, 2022 and the year ended December 31, 2021: Derivative Type Three-Month Year Ended (In thousands) Interest rate swaps $ 2,238,883 $ 1,343,094 TBAs 915,962 1,105,311 Futures 237,025 193,600 Credit default swaps 48,880 110,084 Forwards 17,081 21,188 Options 30,000 13,846 Total return swaps — 2,593 Warrants 3,080 1,948 From time to time the Company enters into credit derivative contracts for which the Company sells credit protection ("written credit derivatives"). As of March 31, 2022 and December 31, 2021, all of the Company's open written credit derivatives were credit default swaps on either mortgage/asset-backed indices (ABX and CMBX indices) or corporate bond indices (CDX), collectively referred to as credit indices, or on individual corporate bonds, for which the Company receives periodic payments at fixed rates from credit protection buyers, and is obligated to make payments to the credit protection buyer upon the occurrence of a "credit event" with respect to underlying reference assets. Written credit derivatives held by the Company at March 31, 2022 and December 31, 2021 are summarized below: Credit Derivatives March 31, 2022 December 31, 2021 (In thousands) Fair Value of Written Credit Derivatives, Net $ 71 $ 124 Notional Value of Written Credit Derivatives (1) 2,664 2,741 (1) The notional value is the maximum amount that a seller of credit protection would be obligated to pay, and a buyer of credit protection would receive, upon occurrence of a "credit event." Movements in the value of credit default swap transactions may require the Company or the counterparty to post or receive collateral. Amounts due or owed under credit derivative contracts with an International Swaps and Derivatives Association, or "ISDA," counterparty may be offset against amounts due or owed on other credit derivative contracts with the same ISDA counterparty. As a result, the notional value of written credit derivatives involving a particular underlying reference asset or index has been reduced (but not below zero) by the notional value of any contracts where the Company has purchased credit protection on the same reference asset or index with the same ISDA counterparty. A credit default swap on a credit index or a corporate bond typically terminates at the stated maturity date in the case of corporate indices or bonds, or, in the case of ABX and CMBX indices, the date that all of the reference assets underlying the index are paid off in full, retired, or otherwise cease to exist. Implied credit spreads may be used to determine the market value of such contracts and are reflective of the cost of buying/selling credit protection. Higher spreads would indicate a greater likelihood that a seller will be obligated to perform ( i.e. , make protection payments) under the contract. In situations where the credit quality of the underlying reference assets has deteriorated, the percentage of notional values that would be paid up front to enter into a new such contract ("points up front") is frequently used as an indication of credit risk. Credit protection sellers entering the market in such situations would expect to be paid points up front corresponding to the approximate fair value of the contract. For the Company's written credit derivatives that were outstanding at March 31, 2022 and December 31, 2021, implied credit spreads on such contracts ranged between 123.7 and 220.5 basis points and 112.7 and 141.1 basis points, respectively. Excluded from these spread ranges are contracts outstanding for which the individual spread is greater than 2,000 basis points. The Company believes that these contracts would be quoted based on estimated points up front. The total fair value of contracts with individual implied credit spreads in excess of 2,000 basis points was $(38) thousand as of both March 31, 2022 and December 31, 2021, respectively. Estimated points up front on these contracts as of both March 31, 2022 and December 31, 2021 ranged between 55.4 and 85.2. Total net up-front payments (paid) or received relating to written credit derivatives outstanding as of both March 31, 2022 and December 31, 2021 were $0.8 million.

Securitization Transactions

Securitization Transactions [Abstract]
Securitization Transactions	Securitization Transactions Participation in CLO Transactions Since June 2017, an affiliate of Ellington has sponsored four CLO securitization transactions (the "Ellington-sponsored CLO Securitizations"), collateralized by corporate loans and managed by an affiliate of Ellington (the "CLO Manager"). Ellington, the Company, several other affiliates of Ellington, and in certain cases, third parties, participated in the Ellington-sponsored CLO Securitizations (collectively, the "CLO Co-Participants"). Pursuant to each Ellington-sponsored CLO Securitization, a newly formed securitization trust (each a "CLO Issuer") issued various classes of notes, which were in turn sold to unrelated third parties and the applicable CLO Co-Participants. The CLO Issuers are each deemed to be a VIE. The Company evaluates its interests in the CLO Issuers under ASC 810, and while the Company retains credit risk in each of the securitization trusts through its beneficial ownership of a portion of the subordinated interests of each of the securitization trusts, which are the first to absorb credit losses on the securitized assets, the Company does not retain control of these assets or the power to direct the activities of the CLO Issuers that most significantly impact the CLO Issuers' economic performance. As a result, the Company determined that it is not the primary beneficiary of the CLO Issuers, and therefore the Company has not consolidated the CLO Issuers. The Company's maximum amount at risk is limited to the Company's investment in each of the CLO Issuers. As of March 31, 2022 and December 31, 2021, the fair value of the Company's investment in the notes issued by the CLO Issuers was $17.2 million and $27.6 million, respectively. See Note 13 for further details on the Company's participation in CLO transactions. Residential Mortgage Loan Securitizations Since November 2017, the Company, through certain wholly owned subsidiaries (each, a "Sponsor"), has sponsored several securitizations of non-QM loans. In each case, the applicable Sponsor transferred a pool of non-QM loans (each, a Collateral Pool") to a wholly owned entity (each, a "Depositor") and on the closing date such loans were deposited into newly created securitization trusts (collectively, the "Issuing Entities"). Pursuant to the securitizations, the Issuing Entities issued various classes of mortgage pass-through certificates (the "Certificates") which are backed by the cash flows from the underlying non-QM loans. Under the Dodd-Frank Act, sponsors of securitizations are generally required to retain at least 5% of the economic interest in the credit risk of the securitized assets (the "Risk Retention Rules"). In order to comply with the Risk Retention Rules, in each securitization, the Company purchased and intends to hold, at a minimum, the requisite amount of the most subordinated classes of Certificates and the excess cash flow certificates. The applicable Sponsor also purchased the Certificates entitled to excess servicing fees in each securitization, while the remaining classes of Certificates were purchased by unrelated parties. Notwithstanding that the Certificates carry final scheduled distribution dates in November 2059 or later, the applicable Depositor may, at its sole option, purchase all of the outstanding Certificates (an "Optional Redemption") following the earlier of (1) the applicable anniversary of the closing date (typically two or three years) of the respective securitization or (2) the date on which the aggregate unpaid principal balance of the applicable Collateral Pool has declined below 30% of the aggregate unpaid principal balance of the applicable Collateral Pool as of the date as of which such loans were originally transferred to the applicable Issuing Entity. The purchase price that the Depositor is required to pay in connection with an Optional Redemption is equal to the sum of the unpaid principal balance of each class of Certificates as of the redemption date and any accrued and unpaid interest thereon. In light of these Optional Redemption rights held by the applicable Depositor, the transfers of non-QM loans to each of the Issuing Entities do not qualify as sales under ASC 860-10. In the event that certain breaches of representations or warranties are discovered with respect to any underlying non-QM loans, the Company could be required to repurchase or replace such loans. Each Sponsor also serves as the servicing administrator of its respective securitization, for which it is entitled to receive a monthly fee equal to one-twelfth of the product of (a) 0.03% and (b) the unpaid principal balance of the underlying non-QM loans as of the first day of the related due period. Each Sponsor in its role as servicing administrator provides direction and consent for certain loss mitigation activities to the third-party servicer of the underlying non-QM loans. In certain circumstances, the servicing administrator will be required to reimburse the servicer for principal and interest advances and servicing advances made by the servicer. In light of the Company's retained interests in each of the securitizations, together with the Optional Redemption rights and the Company's ability to direct the third-party servicer regarding certain loss mitigation activities, the Company is deemed to be the primary beneficiary of the Issuing Entities, which are VIEs, and has consolidated the Issuing Entities. Interest income from these loans and the expenses related to the servicing of these loans are included in Interest income and Investment related expenses—Servicing expense, respectively, on the Consolidated Statement of Operations. The Issuing Entities each meet the definition of a CFE as defined in Note 2, and as a result the assets of each of the Issuing Entities have been valued using the fair value of the liabilities of the respective Issuing Entity, as such liabilities have been assessed to be more observable than such assets. The debt of the Issuing Entities is included in Other secured borrowings, at fair value, on the Consolidated Balance Sheet and is shown net of the Certificates held by the Company. The following table details the Company's outstanding consolidated residential mortgage loan securitizations: Issuing Entity Closing Date Principal Balance of Loans Transferred to the Depositor Total Face Amount of Certificates Issued (In thousands) Ellington Financial Mortgage Trust 2019-2 11/19 $ 267,255 $ 267,255 (1) Ellington Financial Mortgage Trust 2020-1 6/20 259,273 259,273 (2) Ellington Financial Mortgage Trust 2020-2 10/20 219,732 219,732 (3) Ellington Financial Mortgage Trust 2021-1 2/21 251,771 251,771 (4) Ellington Financial Mortgage Trust 2021-2 6/21 331,777 331,777 (5) Ellington Financial Mortgage Trust 2021-3 10/21 257,645 257,645 (6) Ellington Financial Mortgage Trust 2022-1 1/22 417,188 417,188 (7) (1) In order to comply with the Risk Retention Rules, the Sponsor purchased the two most subordinated classes of Certificates and the excess cash flow certificates, with an aggregate value as of the settlement date equal to 6.4% of the fair value of all Certificates issued.

(2) In order to comply with the Risk Retention Rules, the Sponsor purchased the most subordinated class of Certificates and the excess cash flow certificates, with an aggregate value as of the settlement date equal to 5.1% of the fair value of all Certificates issued. Additionally, the Sponsor purchased two other subordinated classes of Certificates with an aggregate value equal to 6.4% of the fair value of all Certificates issued as of the settlement date; the Company subsequently sold such subordinated classes of Certificates to third parties. Finally, the Sponsor also purchased, for an aggregate purchase price of $1.9 million, the Certificates entitled to excess servicing fees, while the remaining classes of Certificates were purchased by unrelated third parties. (3) In order to comply with the Risk Retention Rules, the Sponsor purchased the excess cash flow certificates, with an aggregate value as of the settlement date equal to 5.2% of the fair value of all Certificates issued. Additionally, the Sponsor purchased the most subordinated class of Certificates with an aggregate value as of the settlement date equal to 2.4% of the fair value of all Certificates issued. Finally, the Sponsor also purchased, for an aggregate purchase price of $1.4 million, the Certificates entitled to excess servicing fees, while the remaining classes of Certificates were purchased by unrelated third parties. (4) In order to comply with the Risk Retention Rules, the Sponsor purchased the excess cash flow certificates, with an aggregate value as of the settlement date equal to 5.4% of the fair value of all Certificates issued. Additionally, the Sponsor purchased the most subordinated class of Certificates with an aggregate value as of the settlement date equal to 0.4% of the fair value of all Certificates issued. Finally, the Sponsor also purchased, for an aggregate purchase price of $1.6 million, the Certificates entitled to excess servicing fees, while the remaining classes of Certificates were purchased by unrelated third parties. (5) In order to comply with the Risk Retention Rules, the Sponsor purchased the most subordinated class of Certificates and the excess cash flow certificates, with an aggregate value as of the settlement date equal to 6.5% of the fair value of all Certificates issued. The Sponsor also purchased, for an aggregate purchase price of $2.1 million, the Certificates entitled to excess servicing fees, while the remaining classes of Certificates were purchased by unrelated third parties. (6) In order to comply with the Risk Retention Rules, the Sponsor purchased the most subordinated class of Certificates and the excess cash flow certificates, with an aggregate value as of the settlement date equal to 6.3% of the fair value of all Certificates issued. Additionally, the Sponsor purchased one other subordinated class of Certificates with an aggregate value equal to 2.0% of the fair value of all Certificates issued as of the settlement date. The Sponsor also purchased, for an aggregate purchase price of $1.8 million, the Certificates entitled to excess servicing fees, while the remaining classes of Certificates were purchased by unrelated third parties. (7) In order to comply with the Risk Retention Rules, the Sponsor purchased the most subordinated class of Certificates and the excess cash flow certificates, with an aggregate value as of the settlement date equal to 5.3% of the fair value of all Certificates issued. The Sponsor also purchased, for an aggregate purchase price of $3.6 million, the Certificates entitled to excess servicing fees, while the remaining classes of Certificates were purchased by unrelated third parties. The following table details the assets and liabilities of the consolidated securitization trusts included in the Company's Consolidated Balance Sheet as of March 31, 2022 and December 31, 2021: (In thousands) March 31, 2022 December 31, 2021 Assets: Loans, at fair value $ 1,317,567 $ 1,041,545 Investment related receivables 14,951 23,069 Liabilities: Other secured borrowings, at fair value 1,216,542 984,168 The Company recognized net unrealized gain (loss) on Other secured borrowings, at fair value, of $55.6 million and $1.2 million, during the three-month periods ended March 31, 2022 and 2021, respectively, which is included in Unrealized gains (losses) on other secured borrowings, at fair value, net on the Consolidated Statement of Operations. Participation in Multi-Seller Consumer Loan Securitizations The Company has participated in various securitizations whereby the Company, together with certain other entities managed by Ellington (the "Consumer Co-Participants"), sold consumer loans to newly formed securitization trusts (each a "Consumer Securitization Issuer"). The sales were accounted for as sales in accordance with ASC 860-10. The following table provides additional details for each such securitization. Securitization Closing UPB of Loans Sold to Consumer Securitization Issuer % Contributed by the Company Principal Amount of Notes Issued (1) % Ownership of Consumer Risk Retention Vehicle November 2020 $ 205,088 56.3 % $ 193,650 56.3 % March 2022 (2) 193,450 24.7 % 400,000 24.6 % (1) Total principal amount of notes issued by the Consumer Securitization Issuer pursuant to the securitization. (2) UPB of loans sold to the Consumer Securitization Issuer represent the UPB of consumer loans sold by the Company and the Consumer Co-Participants. Such amount excludes $227.6 million of UPB of consumer loans sold to the Consumer Securitization Issuer by a third-party. As shown in the above table, pursuant to each of the securitizations, the respective Consumer Securitization Issuer issued senior and subordinated notes. Trust certificates representing beneficial ownership of each of the Consumer Securitization Issuers were also issued. In connection with each transaction, through a jointly owned newly formed entity (each a "Consumer Risk Retention Vehicle"), the Company and the Consumer Co-Participants acquired certain of the subordinated notes as well as the trust certificates in the respective Consumer Securitization Issuer. As of March 31, 2022 and December 31, 2021, the Company's total interest in the Consumer Risk Retention Vehicles, for which the Company has elected the FVO, was $18.3 million and $11.5 million, respectively. The fair value of the Consumer Risk Retention Vehicles is included on the Consolidated Balance Sheet in Investments in unconsolidated entities, at fair value. The notes and trust certificates issued by each of the Consumer Securitization Issuer are backed by the cash flows from the underlying consumer loans. If there are breaches of representations and warranties with respect to any underlying consumer loans, the Company could, under certain circumstances, be required to repurchase or replace such loans. Absent such breaches, the Company has no obligation to repurchase or replace any underlying consumer loans that become delinquent or otherwise default. In addition, another affiliate of Ellington acts as the administrator for these securitizations and is paid a monthly fee for its services. The Consumer Securitization Issuers are each deemed to be a VIE. The Company has evaluated its interest in each of the Consumer Securitization Issuers under ASC 810, and while the Company retains credit risk in each of the securitization trusts through its beneficial ownership of most of the subordinated interests of each of the securitization trusts, which are the first to absorb credit losses on the securitized assets, neither the Company nor the Consumer Risk Retention Vehicles retain control of these assets or the power to direct the activities of the Consumer Securitization Issuers that most significantly impact the Consumer Securitization Issuers' economic performance. As a result, the Company determined that neither the Company nor the Consumer Risk Retention Vehicles are the primary beneficiary of the respective Consumer Securitization Issuer, and therefore the Company has not consolidated the Consumer Securitization Issuers. Additionally, the Company evaluated its interest in each of the Consumer Risk Retention Vehicles, which do not meet the criteria to be deemed a VIE, under the voting interest model provided by ASC 810 and determined the Company does not control the Consumer Risk Retention Vehicles. As a result, the Company has not consolidated the Consumer Risk Retention Vehicles.

Borrowings

Debt Disclosure [Abstract]
Borrowings	Borrowings Secured Borrowings The Company's secured borrowings consist of repurchase agreements, Other secured borrowings, and Other secured borrowings, at fair value. As of March 31, 2022 and December 31, 2021, the Company's total secured borrowings were $4.0 billion and $3.6 billion, respectively. Repurchase Agreements The Company enters into repurchase agreements. A repurchase agreement involves the sale of an asset to a counterparty together with a simultaneous agreement to repurchase the transferred asset or similar asset from such counterparty at a future date. The Company accounts for its repurchase agreements as collateralized borrowings, with the transferred assets effectively serving as collateral for the related borrowing. The Company's repurchase agreements typically range in term from 30 to 364 days, although the Company also has repurchase agreements that provide for longer or shorter terms. The principal economic terms of each repurchase agreement—such as loan amount, interest rate, and maturity date—are typically negotiated on a transaction-by-transaction basis. Other terms and conditions, such as those relating to events of default, are typically governed under the Company's master repurchase agreements. Absent an event of default, the Company maintains beneficial ownership of the transferred securities during the term of the repurchase agreement and receives the related principal and interest payments. Interest rates on these borrowings are generally fixed based on prevailing rates corresponding to the terms of the borrowings, and for most repurchase agreements, interest is generally paid at the termination of the repurchase agreement, at which time the Company may enter into a new repurchase agreement at prevailing market rates with the same counterparty, repay that counterparty and possibly negotiate financing terms with a different counterparty, or choose to no longer finance the related asset. Some repurchase agreements provide for periodic payments of interest, such as monthly payments. In response to a decline in the fair value of the transferred securities, whether as a result of changes in market conditions, security paydowns, or other factors, repurchase agreement counterparties will typically make a margin call, whereby the Company will be required to post additional securities and/or cash as collateral with the counterparty in order to re-establish the agreed-upon collateralization requirements. In the event of increases in fair value of the transferred securities, the Company can generally require the counterparty to post collateral with it in the form of cash or securities. The Company is generally permitted to sell or re-pledge any securities posted by the counterparty as collateral; however, upon termination of the repurchase agreement, or other circumstance in which the counterparty is no longer required to post such margin, the Company must return to the counterparty the same security that had been posted. At any given time, the Company seeks to have its outstanding borrowings under repurchase agreements with several different counterparties in order to reduce the exposure to any single counterparty. The Company had outstanding borrowings under repurchase agreements with 23 counterparties as of both March 31, 2022 and December 31, 2021. As of March 31, 2022, remaining days to maturity on the Company's open repurchase agreements ranged from 1 day to 548 days. Interest rates on the Company's open repurchase agreements ranged from 0.14% to 4.22% as of March 31, 2022.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under the Code. A REIT is generally not subject to U.S. federal, state, and local income tax on the portion of its income that is distributed to its owners if it distributes at least 90% of its REIT taxable income within the prescribed time frames, determined without regard to the deduction for dividends paid and excluding any net capital gains. The Company intends to operate in a manner which will allow it to continue to meet the requirements for qualification as a REIT. Accordingly, Ellington Financial Inc. does not believe that it will be subject to U.S. federal, state, and local income tax on the portion of its net taxable income that is distributed to its stockholders as long as certain asset, income, and share ownership tests are met. Cash dividends declared by the Company that do not exceed its current or accumulated earnings and profits will be considered ordinary income to stockholders for income tax purposes unless all or a portion of a dividend is designated by the Company as a capital gain dividend. Distributions in excess of the Company's current and accumulated earnings and profits will be characterized as return of capital or capital gains. The Company accounts for income taxes in accordance with ASC 740, Income Taxes , or "ASC 740." Deferred income taxes reflect the net tax effects of temporary differences that may exist between the carrying amounts of assets and liabilities under U.S. GAAP and the carrying amounts used for income tax purposes. For the three-month period ended March 31, 2022 and 2021, the Company recorded income tax expense (benefit) of $(7.0) million and $2.0 million, respectively. The reversal in the Company's income tax accruals was the result of net realized and unrealized losses in a domestic TRS for the three-month period ended March 31, 2022 as compared to net realized and unrealized gains in a domestic TRS for the three-month period ended March 31, 2021.

Related Party Transactions

Related Party Transactions	3 Months Ended

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions The Company is party to the Management Agreement (which may be amended from time to time), pursuant to which the Manager manages the assets, operations, and affairs of the Company, in consideration of which the Company pays the Manager management and incentive fees. The descriptions of the Base Management Fees and Incentive Fees are detailed below. Base Management Fees The Operating Partnership pays the Manager 1.50% per annum of total equity of the Operating Partnership calculated in accordance with U.S. GAAP as of the end of each fiscal quarter (before deductions for base management fees and incentive fees payable with respect to such fiscal quarter), provided that total equity is adjusted to exclude one-time events pursuant to changes in U.S. GAAP, as well as non-cash charges after discussion between the Manager and the Company's independent directors, and approval by a majority of the Company's independent directors in the case of non-cash charges. Pursuant to the Management Agreement, if the Company invests at issuance in the equity of any collateralized debt obligation that is managed, structured, or originated by Ellington or one of its affiliates, or if the Company invests in any other investment fund or other investment for which Ellington or one of its affiliates receives management, origination, or structuring fees, then, unless agreed otherwise by a majority of the Company's independent directors, the base management and incentive fees payable by the Company to its Manager will be reduced by an amount equal to the applicable portion (as described in the Management Agreement) of any such management, origination, or structuring fees. For the three-month period ended March 31, 2022, the total base management fee incurred was $4.3 million, consisting of $4.9 million of total gross base management fee incurred, less $0.7 million of management fee rebates. For the three-month ended March 31, 2021, the total base management fee incurred was $3.3 million, consisting of $3.5 million of total gross base management fee incurred, less $0.2 million of management fee rebates. See "— Participation in CLO Transactions " below for details on management fee rebates. Incentive Fees The Manager is entitled to receive a quarterly incentive fee equal to the positive excess, if any, of (i) the product of (A) 25% and (B) the excess of (1) Adjusted Net Income (described below) for the Incentive Calculation Period (which means such fiscal quarter and the immediately preceding three fiscal quarters) over (2) the sum of the Hurdle Amounts (described below) for the Incentive Calculation Period, over (ii) the sum of the incentive fees already paid or payable for each fiscal quarter in the Incentive Calculation Period preceding such fiscal quarter. For purposes of calculating the incentive fee, "Adjusted Net Income" for the Incentive Calculation Period means the net increase in equity from operations of the Operating Partnership, after all base management fees but before any incentive fees for such period, and excluding any non-cash equity compensation expenses for such period, as reduced by any Loss Carryforward (as described below) as of the end of the fiscal quarter preceding the Incentive Calculation Period. For purposes of calculating the incentive fee, the "Loss Carryforward" as of the end of any fiscal quarter is calculated by determining the excess, if any, of (1) the Loss Carryforward as of the end of the immediately preceding fiscal quarter over (2) the Company's net increase in equity from operations (expressed as a positive number) or net decrease in equity from operations (expressed as a negative number) of the Operating Partnership for such fiscal quarter. As of March 31, 2022 there was a Loss Carryforward of $9.7 million; there was no Loss Carryforward as of December 31, 2021. For purposes of calculating the incentive fee, the "Hurdle Amount" means, with respect to any fiscal quarter, the product of (i) one-fourth of the greater of (A) 9% and (B) 3% plus the 10-year U.S. Treasury rate for such fiscal quarter, (ii) the sum of (A) the weighted average gross proceeds per share of all common stock and OP Unit issuances since inception of the Company and up to the end of such fiscal quarter, with each issuance weighted by both the number of shares of common stock and OP Units issued in such issuance and the number of days that such issued shares of common stock and OP Units were outstanding during such fiscal quarter, using a first-in first-out basis of accounting ( i.e. attributing any share of common stock and OP Unit repurchases to the earliest issuances first) and (B) the result obtained by dividing (I) retained earnings attributable to shares of common stock and OP Units at the beginning of such fiscal quarter by (II) the average number of shares of common stock and OP Units outstanding for each day during such fiscal quarter, and (iii) the sum of (x) the average number of shares of common stock and long term incentive plan units of the Company outstanding for each day during such fiscal quarter, and (y) the average number of Convertible Non-controlling Interests outstanding for each day during such fiscal quarter. For purposes of determining the Hurdle Amount, issuances of common stock, and Convertible Non-controlling Interests (a) as equity incentive awards, (b) to the Manager as part of its base management fee or incentive fee and (c) to the Manager or any of its affiliates in privately negotiated transactions, are excluded from the calculation. The payment of the incentive fee will be in a combination of shares of common stock and cash, provided that at least 10% of any quarterly payment will be made in shares of common stock. The Company did not accrue an incentive fee for either of the three-month periods ended March 31, 2022 or 2021, since on a rolling four quarter basis, the Company's income did not exceed the prescribed hurdle amount. Termination Fees The Management Agreement requires the Company to pay a termination fee to the Manager in the event of (1) the Company's termination or non-renewal of the Management Agreement without cause or (2) the Company's termination of the Management Agreement based on unsatisfactory performance by the Manager that is materially detrimental to the Company or (3) the Manager's termination of the Management Agreement upon a default by the Company in the performance of any material term of the Management Agreement. Such termination fee will be equal to the amount of three times the sum of (i) the average annual quarterly base management fee amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal and (ii) the average annual quarterly incentive fee amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal. Expense Reimbursement Under the terms of the Management Agreement the Company is required to reimburse the Manager for operating expenses related to the Company that are incurred by the Manager, including expenses relating to legal, accounting, due diligence, other services, and all other costs and expenses. The Company's reimbursement obligation is not subject to any dollar limitation. Expenses will be reimbursed in cash within 60 days following delivery of the expense statement by the Manager; provided, however, that such reimbursement may be offset by the Manager against amounts due to the Company from the Manager. The Company will not reimburse the Manager for the salaries and other compensation of the Manager's personnel except that the Company will be responsible for expenses incurred by the Manager in employing certain dedicated or partially dedicated personnel as further described below. The Company reimburses the Manager for the allocable share of the compensation, including, without limitation, wages, salaries, and employee benefits paid or reimbursed, as approved by the Compensation Committee of the Board of Directors to certain dedicated or partially dedicated personnel who spend all or a portion of their time managing the Company's affairs, based upon the percentage of time devoted by such personnel to the Company's affairs. In their capacities as officers or personnel of the Manager or its affiliates, such personnel will devote such portion of their time to the Company's affairs as is necessary to enable the Company to operate its business. For the three-month periods ended March 31, 2022 and 2021, the Company reimbursed the Manager $5.7 million and $4.1 million, respectively, for previously incurred operating expenses. As of March 31, 2022 and December 31, 2021, the outstanding payable to the Manager for operating expenses was $4.0 million and $3.7 million, respectively, which are included in Accrued expenses and other liabilities on the Consolidated Balance Sheet. Transactions Involving Certain Loan Originators As of March 31, 2022 and December 31, 2021, the loan originators in which the Company holds equity investments represent related parties. Transactions that have been entered into with these related party loan originators are summarized below. The Company is a party to a mortgage loan purchase and sale flow agreement, with a mortgage loan originator in which the Company holds a non-controlling equity investment, whereby the Company purchases residential mortgage loans that satisfy certain specified criteria. The Company has also provided a $5.0 million line of credit to the mortgage originator. Under the terms of this line of credit, the Company has agreed to make advances to the mortgage originator solely for the purpose of funding specifically identified residential mortgage loans designated for sale to the Company. To the extent the advances are drawn by the mortgage originator, it must pay interest, at a rate of 15% per annum, on the outstanding balance of each advance from the date the advance is made until such advance is repaid in full. The mortgage originator is required to repay advances in full no later than two business days following the date that the Company purchases the related residential mortgage loans from the mortgage originator. As of both March 31, 2022 and December 31, 2021, there were no advances outstanding. The Company has also entered into agreements whereby it guarantees the performance of such mortgage originator under third-party master repurchase agreements. See Note 21, Commitments and Contingencies, for further information on the Company's guarantees of the third-party borrowing arrangements. Additionally, in August 2020, the Company entered into a commitment agreement whereby the Company committed to purchase $150 million of residential mortgage loans. In connection with satisfying the conditions set forth under such commitment agreement, the Company received warrants to purchase a maximum of 9.329 million shares of non-voting common stock. In December 2021, warrants to purchase 1.049 million shares of non-voting common stock were terminated. As of both March 31, 2022 and December 31, 2021, the Company held warrants to purchase 8.28 million shares; such warrants have a fair value of $9.1 million and $10.0 million, respectively, and are included in Investments in unconsolidated entities on the Consolidated Balance Sheet. The Company, through a related party of Ellington, or the "Loan Purchaser," is a party to a consumer loan purchase and sale flow agreement with a consumer loan originator in which the Company holds an investment in common and preferred stock and warrants to purchase additional preferred stock, whereby the Loan Purchaser purchases consumer loans that satisfy certain specified criteria. The Company has investments in participation certificates related to consumer loans titled in the name of the Loan Purchaser. Through its participation certificates, the Company has beneficial interests in the loan cash flows, net of servicing-related fees and expenses. The total fair value of the Company's participation certificates was $76.5 million and $72.8 million as of March 31, 2022 and December 31, 2021, respectively, which is included in Securities, at fair value on the Consolidated Balance Sheet. An employee of Ellington has a less-than-10% equity interest in, and serves on the board of, this consumer loan originator. Another employee of Ellington, who serves as an officer of the Company, also serves on the board, as the Company's representative. The following table provides details of financing that the Company has provided, in the form of secured promissory notes, to certain loan origination-related entities in which the Company also holds equity investments: Effective Date of Promissory Note Maturity Date of Promissory Note Interest Rate Outstanding Borrowings as of Fair Value (1) as of Maximum Borrowing March 31, 2022 December 31, 2021 March 31, 2022 December 31, 2021 March 31, 2022 December 31, 2021 (In thousands) (In thousands) May 2021 (2) December 31, 2025 $ 6,000 3.0% 3.0% $ 3,000 $ 3,000 $ 3,000 $ 3,000 November 2021 November 19, 2024 3,000 9.0% 9.0% 1,500 — 1,500 — February 2022 January 31, 2025 500 7.0% — 150 — 150 — (1) Classified as a Corporate loan and is included in Loans, at fair value on the Consolidated Balance Sheet. (2) Convertible into non-voting equity interests, at the option of the borrower, at any time prior to maturity. Consumer, Residential, and Commercial Loan Transactions with Affiliates The Company purchases certain of its consumer loans through an affiliate, or the "Purchasing Entity." The Purchasing Entity has entered into purchase agreements, open-ended in duration, with third party consumer loan originators whereby it has agreed to purchase eligible consumer loans. The amount of loans purchased under these purchase agreements is dependent on, among other factors, the amount of loans originated in any given period by the selling originators. The Company and certain other affiliates of Ellington have entered into agreements with the Purchasing Entity whereby the Company and each of those other affiliates of Ellington have agreed to purchase their allocated portion (subject to monthly determination based on available capital and other factors) of the eligible loans acquired by the Purchasing Entity under each purchase agreement. Immediately after the Purchasing Entity purchases beneficial interests in the loans, the Company and other affiliates of Ellington purchase such beneficial interests from the Purchasing Entity, at the same price paid by the Purchasing Entity. During the three-month periods ended March 31, 2022 and 2021, the Company purchased loans under these agreements with an aggregate principal balance of $10.0 million and $11.9 million, respectively. As of December 31, 2021, the estimated remaining contingent purchase obligations of the Company under these purchase agreements was approximately $13.4 million in principal balance; as of March 31, 2022, there were no remaining contingent purchase obligations. The Company's beneficial interests in the consumer loans purchased through the Purchasing Entity are evidenced by participation certificates issued by trusts that hold legal title to the loans. These trusts are owned by a related party of Ellington and were established to hold such loans. Through its participation certificates, the Company participates in the cash flows of the underlying loans held by each trust. The total amount of consumer loans underlying the Company's participation certificates and held in the related party trusts was $9.3 million and $61.7 million as of March 31, 2022 and December 31, 2021, respectively. The Company has beneficial interests in residential mortgage loans and REO held in a trust owned by a related party of Ellington. Through these beneficial interests, the Company participates in the cash flows of the underlying loans held by such trust. The total amount of residential mortgage loans and REO underlying the Company's beneficial interests and held in the related party trust was $1.117 billion and $975.7 million as of March 31, 2022 and December 31, 2021, respectively. The Company is a co-investor in certain small balance commercial mortgage loans with several other investors, including an unrelated third party and various affiliates of Ellington. These loans are beneficially owned by a consolidated subsidiary of the Company. As of March 31, 2022 and December 31, 2021, the aggregate fair value of these small balance commercial loans was $16.0 million and $34.0 million, respectively. As of March 31, 2022, the non-controlling interests held by the unrelated third party and the Ellington affiliates were $1.2 million and $1.9 million, respectively. As of December 31, 2021, the non-controlling interests held by the unrelated third party and the Ellington affiliates were $2.0 million and $3.6 million, respectively. The Company is also a co-investor in certain small balance commercial mortgage loans and REO with other investors, including various unrelated third parties and various affiliates of Ellington. Each co-investor in a particular loan has an interest in the limited liability company that owns such loan or REO. As of March 31, 2022 and December 31, 2021, the aggregate fair value of the Company's investments in the jointly owned limited liability companies was approximately $63.7 million and $36.9 million, respectively. Such investments are included in Investments in unconsolidated entities, on the Consolidated Balance Sheet. The consumer, residential mortgage, and certain commercial mortgage loans that are the subject of the foregoing loan transactions are held in trusts, each of which the Company has determined to be a VIE. The Company has evaluated each of these VIEs and determined that the Company has the power to direct the activities of each VIE that most significantly impact such VIE's economic performance and the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. As a result the Company has determined it is the primary beneficiary of each of these VIEs and has consolidated each VIE. Equity Investment in Unconsolidated Entity The Company is a co-investor, together with other affiliates of Ellington, in Jepson Holdings Limited ("Jepson"), the parent of an entity (the "Jepson Risk Retention Vehicle") that has sponsored various European mortgage loan securitizations. The Jepson Risk Retention Vehicle is expected to hold certain of the notes it issues for each securitization it completes in order to comply with European risk retention rules. As of both March 31, 2022 and December 31, 2021, the Company's equity investment in Jepson Holdings Limited had a fair value of $1.0 million. See Note 6 for additional details on this equity investment. Participation in Multi-Borrower Financing Facilities The Company is a co-participant with certain other entities managed by Ellington or its affiliates (the "Affiliated Entities") in various entities (each, a "Joint Entity"), which were formed in order to facilitate the financing of small balance commercial mortgage loans, residential mortgage loans, and REO (collectively, the "Mortgage Loan and REO Assets"), through repurchase agreements. Each Joint Entity has a master repurchase agreement with a particular financing counterparty. In connection with the financing of the Mortgage Loan and REO Assets under repurchase agreements, each of the Company and the Affiliated Entities transferred certain of their respective Mortgage Loan and REO Assets to one of the Joint Entities in exchange for its pro rata share of the financing proceeds that the respective Joint Entity received from the financing counterparty. While the Company's Mortgage Loan and REO Assets were transferred to the Joint Entity, the Company's Mortgage Loan and REO Assets and the related debt were not derecognized for financial reporting purposes, in accordance with ASC 860-10, because the Company continued to retain the risks and rewards of ownership of its Mortgage Loan and REO Assets. As of March 31, 2022 and December 31, 2021, the Joint Entities had aggregate outstanding issued debt under the repurchase agreements in the amount of $837.6 million and $566.0 million, respectively. The Company's segregated silo of this debt as of March 31, 2022 and December 31, 2021 was $229.3 million and $150.5 million, respectively, and is included under the caption Repurchase agreements on the Company's Consolidated Balance Sheet. To the extent that there is a default under the repurchase agreements, all of the assets of each respective Joint Entity, including those beneficially owned by any non-defaulting owners of such Joint Entity, could be used to satisfy the outstanding obligations under such repurchase agreement. As of both March 31, 2022 and December 31, 2021, no party to any of the repurchase agreements was in default. Each of the Joint Entities has been determined to be a VIE. The Company has evaluated each of these VIEs and determined that it continued to retain the risks and rewards of ownership of certain of the Mortgage Loan and REO Assets, where such Mortgage Loan and REO Assets and the related debt are segregated for the Company and each of the Affiliated Entities. On account of the segregation of certain of each co-participant's assets and liabilities within each of the Joint Entities, as well as the retention by each co-participant of control over its segregated Mortgage Loan and REO Assets within the Joint Entities, the Company has determined that it is the primary beneficiary of, and has consolidated its segregated silo of assets and liabilities within, each of the Joint Entities. See Note 9 and Note 11 for additional information. Participation in CLO Transactions As discussed in Note 10, the Company participated in a number of CLO securitization transactions, all managed by the CLO Manager. The CLO Manager is entitled to receive management and incentive fees in accordance with the respective management agreements between the CLO Manager and the respective CLO Issuers. In accordance with the Management Agreement, the Manager rebates to the Company the portion of the management fees payable by each CLO Issuer to the CLO Manager that are allocable to the Company's participating interest in the unsecured subordinated notes issued by such CLO Issuer. For the three-month periods ended March 31, 2022 and 2021, the amount of such management fee rebates was $0.7 million and $0.2 million, respectively. In addition, from time to time, the Company along with various other affiliates of Ellington, and in certain cases various third parties, advance funds in the form of loans ("Initial Funding Loans") to securitization vehicles to enable them to establish warehouse facilities for the purpose of acquiring the assets to be securitized. Pursuant to the terms of the warehouse facilities and the Initial Funding Loans, the applicable securitization trust is required, at the closing of each respective CLO securitization, first to repay the warehouse facility, then to repay the Initial Funding Loans, and then to distribute interest earned, net of any necessary reserves and/or interest expense, and the aggregate realized or unrealized gains, if any, on assets purchased into the warehouse facility. In the event that such CLO securitization fails to close, the assets held by the respective securitization vehicle would, subject to a cure period, be liquidated. As of March 31, 2022 and December 31, 2021, the Company's investment in such warehouse facilities was $0.6 million and $1.7 million, respectively, which are included on the Consolidated Balance Sheet in Investments in unconsolidated entities.

Offsetting of Assets and Liabilities [Abstract]
Offsetting of Assets and Liabilities	Offsetting of Assets and LiabilitiesThe Company generally records financial instruments at fair value as described in Note 2. Financial instruments are generally recorded on a gross basis on the Consolidated Balance Sheet. In connection with the vast majority of its derivative, reverse repurchase and repurchase agreements, and the related trading agreements, the Company and its counterparties are required to pledge collateral. Cash or other collateral is exchanged as required with each of the Company's counterparties in connection with open derivative positions, and reverse repurchase and repurchase agreements. The following tables present information about certain assets and liabilities representing financial instruments as of March 31, 2022 and December 31, 2021. The Company has not entered into master netting agreements with any of its counterparties. Certain of the Company's reverse repurchase and repurchase agreements and financial derivative transactions are governed by underlying agreements that generally provide a right of net settlement, as well as a right of offset in the event of default or in the event of a bankruptcy of either party to the transaction. March 31, 2022: Description Amount of Assets (Liabilities) Presented in the Consolidated Balance Sheet (1) Financial Instruments Available for Offset Financial Instruments Transferred or Pledged as Collateral (2)(3) Cash Collateral (Received) Pledged (2)(3) Net Amount (In thousands) Assets Financial derivatives–assets $ 65,082 $ (15,656) $ — $ (18,080) $ 31,346 Reverse repurchase agreements 131,243 (54,344) (76,899) — — Liabilities Financial derivatives–liabilities (16,528) 15,656 — 648 (224) Repurchase agreements (2,717,638) 54,344 2,562,488 100,806 — (1) In the Company's Consolidated Balance Sheet, all balances associated with repurchase agreements, reverse repurchase agreements, and financial derivatives are presented on a gross basis. (2) For the purpose of this presentation, for each row the total amount of financial instruments transferred or pledged and cash collateral (received) or pledged may not exceed the applicable gross amount of assets or (liabilities) as presented here. Therefore, the Company has reduced the amount of financial instruments transferred or pledged as collateral related to the Company's repurchase agreements and cash collateral pledged on the Company's financial derivative liabilities. Total financial instruments transferred or pledged as collateral on the Company's repurchase agreements as of March 31, 2022 was $3.1 billion. As of March 31, 2022, total cash collateral on financial derivative assets and liabilities excludes excess net cash collateral pledged (received) of $1.3 million and $2.0 million, respectively. (3) When collateral is pledged to or pledged by a counterparty, it is often pledged or posted with respect to all positions with such counterparty, and in such cases such collateral cannot be specifically identified as relating to a particular asset or liability. As a result, in preparing the above tables, the Company has made assumptions in allocating pledged or posted collateral among the various rows.

(2) For the purpose of this presentation, for each row the total amount of financial instruments transferred or pledged and cash collateral (received) or pledged may not exceed the applicable gross amount of assets or (liabilities) as presented here. Therefore, the Company has reduced the amount of financial instruments transferred or pledged as collateral related to the Company's repurchase agreements and cash collateral pledged on the Company's financial derivative liabilities. Total financial instruments transferred or pledged as collateral on the Company's repurchase agreements as of December 31, 2021 was $2.8 billion. As of December 31, 2021, total cash collateral on financial derivative assets and liabilities excludes excess net cash collateral pledged of $10.7 million and $2.0 million, respectively. (3) When collateral is pledged to or pledged by a counterparty, it is often pledged or posted with respect to all positions with such counterparty, and in such cases such collateral cannot be specifically identified as relating to a particular asset or liability. As a result, in preparing the above tables, the Company has made assumptions in allocating pledged or posted collateral among the various rows.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	Commitments and Contingencies The Company provides current directors and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Company. In the normal course of business the Company may also enter into contracts that contain a variety of representations, warranties, and general indemnifications. The Company's maximum exposure under these arrangements, including future claims that may be made against the Company that have not yet occurred, is unknown. The Company has not incurred any costs to defend lawsuits or settle claims related to these indemnification agreements. As of both March 31, 2022 and December 31, 2021, the Company has no liabilities recorded for these agreements. The Company's maximum risk of loss from credit events on its securities (excluding Agency securities, which are guaranteed by the issuing government agency or government-sponsored enterprise), loans, and investments in unconsolidated entities is limited to the amount paid for such investment. Commitments and Contingencies Related to Investments in Residential Mortgage Loans In connection with certain of the Company's investments in residential mortgage loans, the Company has unfunded commitments in the amount of $76.3 million and $43.7 million as of March 31, 2022 and December 31, 2021, respectively. Commitments and Contingencies Related to Investments in Mortgage Loan Originators In connection with certain of its investments in mortgage loan originators, the Company has outstanding commitments and contingencies as described below. As described in Note 13, the Company is party to a flow mortgage loan purchase and sale agreement with a mortgage loan originator. The Company has entered into agreements whereby it guarantees the performance of this mortgage loan originator under master repurchase agreements. The Company's maximum guarantees were capped at $15.0 million as of both March 31, 2022 and December 31, 2021. As of March 31, 2022 and December 31, 2021, the mortgage loan originator had $13.2 million and $8.4 million, respectively, of outstanding borrowings under the agreements guaranteed by the Company. The Company's obligations under these arrangements are deemed to be guarantees under ASC 460-10. The Company has elected the FVO for its guarantees, which are included in Accrued expenses and other liabilities on the Consolidated Balance Sheet. As of both March 31, 2022 and December 31, 2021, the estimated fair value of such guarantees was insignificant. The Company is party to a flow mortgage loan purchase and sale agreement with a mortgage loan originator in which it holds an equity investment and as well as an investment in the Convertible Note, as discussed in Note 13. In addition, in May 2021, the Company committed to purchase $650.0 million of eligible residential mortgage loans. As of March 31, 2022 and December 31, 2021, the Company had unfunded commitments related to such investments in the amount of $522.3 million and $603.6 million, respectively.

Basis of Presentation	Basis of Presentation: The Company's unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America, or "U.S. GAAP," and Regulation S-X. The condensed consolidated financial statements include the accounts of the Company, the Operating Partnership, its subsidiaries, and variable interest entities, or "VIEs," for which the Company is deemed to be the primary beneficiary. All intercompany balances and transactions have been eliminated. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and those differences could be material. In management's opinion, all material adjustments considered necessary for a fair statement of the Company's consolidated financial statements have been included and are only of a normal recurring nature. Interim results are not necessarily indicative of the results that may be expected for the entire fiscal year. The information included in the condensed consolidated financial statements and notes thereto should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2021.
Valuation	Valuation : The Company applies ASC 820-10, Fair Value Measurement ("ASC 820") to its holdings of financial instruments. ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: • Level 1—inputs to the valuation methodology are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Currently, the types of financial instruments the Company generally includes in this category are listed equities and exchange-traded derivatives; • Level 2—inputs to the valuation methodology other than quoted prices included in Level 1 are observable for the asset or liability, either directly or indirectly. Currently, the types of financial instruments that the Company generally includes in this category are RMBS, for which the principal and interest payments are guaranteed by a U.S. government agency or a U.S. government-sponsored entity, or "Agency RMBS," U.S. Treasury securities and sovereign debt, certain non-Agency RMBS, CMBS, CLOs, corporate debt, and actively traded derivatives such as interest rate swaps, foreign currency forwards, and other over-the-counter derivatives; and • Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement. The types of financial instruments that the Company generally includes in this category are certain RMBS, CMBS, CLOs, ABS, credit default swaps, or "CDS," on individual ABS, and total return swaps on distressed corporate debt, in each case where there is less price transparency. Also included in this category are residential and commercial mortgage loans, consumer loans, and private corporate debt and equity investments. For certain financial instruments, the various inputs that management uses to measure fair value may fall into different levels of the fair value hierarchy. For each such financial instrument, the determination of which category within the fair value hierarchy is appropriate is based on the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the various inputs that management uses to measure fair value, with the highest priority given to inputs that are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets (Level 1), and the lowest priority given to inputs that are unobservable and significant to the fair value measurement (Level 3). The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. The Company may use valuation techniques consistent with the market and income approaches to measure the fair value of its financial instruments. The market approach uses third-party valuations and information obtained from market transactions involving identical or similar financial instruments. The income approach uses projections of the future economic benefit of an instrument to determine its fair value, such as in the discounted cash flow methodology. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risk associated with investing in these financial instruments. The leveling of each financial instrument is reassessed at the end of each period. Transfers between levels of the fair value hierarchy are assumed to occur at the end of the reporting period. Summary Valuation Techniques For financial instruments that are traded in an "active market," the best measure of fair value is the quoted market price. However, many of the Company's financial instruments are not traded in an active market. Therefore, management generally uses third-party valuations when available. If third-party valuations are not available, management uses other valuation techniques, such as the discounted cash flow methodology. The following are summary descriptions, for various categories of financial instruments, of the valuation methodologies management uses in determining fair value of the Company's financial instruments in such categories. Management utilizes such methodologies to assign a fair value (the estimated price that, in an orderly transaction at the valuation date, would be received to sell an asset, or paid to transfer a liability, as the case may be) to each such financial instrument. For mortgage-backed securities, or "MBS," forward settling to-be-announced mortgage-backed-securities, or "TBAs," CLOs, and corporate debt and equity, management seeks to obtain at least one third-party valuation, and often obtains multiple valuations when available. Management has been able to obtain third-party valuations on the vast majority of these instruments and expects to continue to solicit third-party valuations in the future. Management generally values each financial instrument at the average of third-party valuations received and not rejected as described below. Third-party valuations are not binding, management may adjust the valuations it receives (e.g., downward adjustments for odd lots), and management may challenge or reject a valuation when, based on its validation criteria, management determines that such valuation is unreasonable or erroneous. Furthermore, based on its validation criteria, management may determine that the average of the third-party valuations received for a given financial instrument does not result in what management believes to be the fair value of such instrument, and in such circumstances management may override this average with its own good faith valuation. The validation criteria may take into account output from management's own models, recent trading activity in the same or similar instruments, and valuations received from third parties. The use of proprietary models requires the use of a significant amount of judgment and the application of various assumptions including, but not limited to, assumptions concerning future prepayment rates and default rates. Given their relatively high level of price transparency, Agency RMBS pass-throughs are typically classified as Level 2. Non-Agency RMBS, CMBS, Agency interest only and inverse interest only RMBS, CLOs, and corporate bonds are generally classified as either Level 2 or Level 3 based on analysis of available market data and/or third-party valuations. The Company's investments in distressed corporate debt can be in the form of loans as well as total return swaps on loans. These investments, as well as related non-listed equity investments, are generally designated as Level 3 assets. Valuations for total return swaps are typically based on prices of the underlying loans received from third-party pricing services. Private equity investments are generally classified as Level 3. Furthermore, the methodology used by the third-party valuation providers is reviewed at least annually by management, so as to ascertain whether such providers are utilizing observable market data to determine the valuations that they provide. For residential and commercial mortgage loans, and consumer loans, management determines fair value by taking into account both external pricing data, which includes third-party valuations, and internal pricing models. Management has obtained third-party valuations on the majority of these investments and expects to continue to solicit third-party valuations in the future. In determining fair value for non-performing mortgage loans, management evaluates third-party valuations, if applicable, as well as management's estimates of the value of the underlying real estate, using information including general economic data, broker price opinions, or "BPOs," recent sales, property appraisals, and bids. In determining fair value for performing mortgage loans and consumer loans, management evaluates third-party valuations, if applicable, as well as discounted cash flows of the loans based on market assumptions. Cash flow assumptions typically include projected default and prepayment rates and loss severities, and may include adjustments based on appraisals and BPOs. Mortgage and consumer loans are classified as Level 3. The Company has securitized certain mortgage loans that are not deemed "qualified mortgage," or "QM," loans under the rules of the Consumer Financial Protection Bureau, or "non-QM loans." The Company's securitized non-QM loans are held as part of a collateralized financing entity, or "CFE." A CFE is a VIE that holds financial assets, issues beneficial interests in those assets, and has no more than nominal equity, and for which the issued beneficial interests have contractual recourse only to the related assets of the CFE. ASC 810, Consolidation ("ASC 810") allows the Company to elect to measure both the financial assets and financial liabilities of the CFE using the more observable of the fair value of the financial assets and the fair value of the financial liabilities of the CFE. The Company has elected the fair value option, or "FVO," for initial and subsequent recognition of the debt issued by its consolidated securitization trusts and has determined that each consolidated securitization trust meets the definition of a CFE; see Note 10 " Securitization Transactions — Residential Mortgage Loan Securitizations " for further discussion on the Company's securitization trusts. The Company has determined the inputs to the fair value measurement of the financial liabilities of each of its CFEs to be more observable than those of the financial assets and, as a result, has used the fair value of the financial liabilities of each of the CFEs to measure the fair value of the financial assets of each of the CFEs. The fair value of the debt issued by each CFE is typically valued using both external pricing data, which includes third-party valuations, and internal pricing models. The securitized non-QM loans, which are assets of the CFEs, are included in Loans, at fair value, on the Company's Consolidated Balance Sheet. The debt issued by the CFEs is included in Other secured borrowings, at fair value, on the Company's Consolidated Balance Sheet. Unrealized gains (losses) from changes in fair value of Other secured borrowings, at fair value, are included in Unrealized gains (losses) on other secured borrowings, at fair value, net, on the Company's Consolidated Statement of Operations. The securitized non-QM loans and the debt issued by the Company's CFEs are both classified as Level 3. For financial derivatives with greater price transparency, such as CDS on asset-backed indices, CDS on corporate indices, certain options on the foregoing, and total return swaps on publicly traded equities or indices, market-standard pricing sources are used to obtain valuations; these financial derivatives are generally classified as Level 2. Interest rate swaps, swaptions, and foreign currency forwards are typically valued based on internal models that use observable market data, including applicable interest rates and foreign currency rates in effect as of the measurement date; the model-generated valuations are then typically compared to counterparty valuations for reasonableness. These financial derivatives are also generally classified as Level 2. Financial derivatives with less price transparency, such as CDS on individual ABS, are generally valued based on internal models, and are classified as Level 3. In the case of CDS on individual ABS, the valuation process typically starts with an estimation of the value of the underlying ABS. In valuing its financial derivatives, the Company also considers the creditworthiness of both the Company and its counterparties, along with collateral provisions contained in each financial derivative agreement. Investments in private operating entities, such as loan originators, are valued based on available metrics, such as relevant market multiples and comparable company valuations, company specific-financial data including actual and projected results, and independent third party valuation estimates. These investments are classified as Level 3. The Company's repurchase and reverse repurchase agreements are carried at cost, which approximates fair value. Repurchase and reverse repurchase agreements are classified as Level 2, based on the adequacy of the collateral and their short term nature. The Company's valuation process, including the application of validation criteria, is directed by the Manager's Valuation Committee (the "Valuation Committee"), and overseen by the Company's audit committee. The Valuation Committee includes
Accounting for Securities	Accounting for Securities : Purchases and sales of investments in securities are generally recorded on trade date, and realized and unrealized gains and losses are calculated based on identified cost. Investments in securities are recorded in accordance with ASC 320, Investments—Debt and Equity Securities ("ASC 320") or ASC 325-40, Beneficial Interests in Securitized Financial Assets ("ASC 325-40"). The Company generally classifies its securities as available-for-sale. The Company has chosen to elect the FVO pursuant to ASC 825, Financial Instruments ("ASC 825") for its investments in securities. Electing the FVO allows the Company to record changes in fair value in the Consolidated Statement of Operations, as a component of Unrealized gains (losses) on securities and loans, net, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all investment activities will be recorded in a similar manner. Many of the Company's investments in securities, such as MBS and CLOs, are issued by entities that are deemed to be VIEs. For the majority of such investments, the Company has determined it is not the primary beneficiary of such VIEs and therefore has not consolidated such VIEs. The Company's maximum risk of loss in these unconsolidated VIEs is generally limited to the fair value of the Company's investment in the VIE. The Company evaluates its investments in interest only securities to determine whether they meet the requirements for classification as financial derivatives under ASC 815, Derivatives and Hedging ("ASC 815"). For interest only securities, where the holder is entitled only to a portion of the interest payments made on the mortgages underlying certain MBS, and inverse interest only securities, which are interest only securities whose coupon has an inverse relationship to its benchmark rate, such as LIBOR, the Company has determined that such investments do not meet the requirements for treatment as financial derivatives and are classified as securities. The Company applies the principles of ASU 2016-13, Financial Instruments—Credit Losses ("ASU 2016-13") and evaluates the cost basis of its investments in securities on at least a quarterly basis, under ASC 326-30, Financial Instruments—Credit Losses: Available-for-Sale Debt Securities ("ASC 326-30"). When the fair value of a security is less than its amortized cost basis as of the balance sheet date, the security's cost basis is considered impaired. The Company must evaluate the decline in the fair value of the impaired security and determine whether such decline resulted from a credit loss or non-credit related factors. In its assessment of whether a credit loss exists, the Company compares the present value of estimated future cash flows of the impaired security with the amortized cost basis of such security. The estimated future cash flows reflect those that a "market participant" would use and typically include assumptions related to fluctuations in interest rates, prepayment speeds, default rates, collateral performance, and the timing and amount of projected credit losses, as well incorporating observations of current market developments and events. Cash flows are discounted at an interest rate equal to the current yield used to accrete interest income. If the present value of estimated future cash flows is less than the amortized cost basis of the security, an expected credit loss exists and is included in Unrealized gains (losses) on securities and loans, net, on the Consolidated Statement of Operations. If it is determined as of the financial reporting date that all or a portion of a security's cost basis is not collectible, then the Company will recognize a realized loss to the extent of the adjustment to the security's cost basis. This adjustment to the amortized cost basis of the security is reflected in Net realized gains (losses) on securities and loans, net, on the Consolidated Statement of Operations.
Accounting for Loans	Accounting for Loans : The Company's loan portfolio primarily consists of residential mortgage, commercial mortgage, and consumer loans. The Company's loans are accounted for under ASC 310-10, Receivables , and are classified as held-for-investment when the Company has the intent and ability to hold such loans for the foreseeable future or to maturity/payoff. When the Company has the intent to sell loans, such loans will be classified as held-for-sale. Mortgage loans held-for-sale are accounted for under ASC 948-310, Financial services—mortgage banking. The Company may aggregate its loans into pools based on common risk characteristics at purchase. The Company has chosen to elect the FVO pursuant to ASC 825 for its loan portfolios. Loans are recorded at fair value on the Consolidated Balance Sheet and changes in fair value are recorded in earnings on the Consolidated Statement of Operations as a component of Unrealized gains (losses) on securities and loans, net. The Company generates income from fees on certain loans, generally commercial mortgage loans, that it originates and holds for investment, including origination and exit fees. Such fee income is recorded when earned and included in Other, net on the Consolidated Statement of Operations. Transfers between held-for-investment and held-for-sale occur once the Company's intent to sell the loans changes. For residential and commercial mortgage loans, the Company generally accrues interest payments. Such loans are typically moved to non-accrual status if the loan becomes 90 days or more delinquent. The Company does not accrue interest payments on its consumer loans; interest payments are recorded upon receipt. Once consumer loans are more than 120 days past due, the Company will generally charge off such loans. The Company evaluates its charged-off loans and determines collectibility, if any, on such loans. The Company evaluates the collectibility of both interest and principal on each of its loan investments and whether the cost basis of the loan is impaired. A loan's cost basis is impaired when, based on current information and market developments, it is probable that the Company will be unable to collect all amounts due according to the existing contractual terms. When a loan's cost basis is impaired, the Company does not record an allowance for loan loss as it elected the FVO on all of its loan investments. Consistent with the Company's application of the principles of ASU 2016-13, in its assessment of whether a credit loss exists, the Company compares the present value of the amount expected to be collected on the impaired loan with the amortized cost basis of such loan. If the present value of the amount expected to be collected on the impaired loan is less than the amortized cost basis of such loan, an expected credit loss exists and is included in Unrealized gains (losses) on securities and loans, net, on the Consolidated Statement of Operations. If it is determined as of the financial reporting date that all or a portion of a loan's cost basis is not collectible, then the Company will recognize a realized loss to the extent of the adjustment to the loan's cost basis. This adjustment to the amortized cost basis of the loan is reflected in Realized gains (losses) on securities and loans, net, on the Consolidated Statement of Operations.
Interest Income	Interest Income: The Company amortizes premiums and accretes discounts on its debt securities. Coupon interest income on fixed-income investments is generally accrued based on the outstanding principal balance or notional value and the current coupon rate. For debt securities that are deemed to be of high credit quality at the time of purchase (generally Agency RMBS, exclusive of interest only securities), premiums and discounts are amortized/accreted into interest income over the life of such securities using the effective interest method. For such securities whose cash flows vary depending on prepayments, an effective yield retroactive to the time of purchase is periodically recomputed based on actual prepayments and changes in projected prepayment activity, and a catch-up adjustment, or "Catch-up Premium Amortization Adjustment," is made to amortization to reflect the cumulative impact of the change in effective yield. For debt securities (generally non-Agency RMBS, CMBS, ABS, CLOs, and interest only securities) that are deemed not to be of high credit quality at the time of purchase, interest income is recognized based on the effective interest method. For purposes of estimating future expected cash flows, management uses assumptions including, but not limited to, assumptions for future prepayment rates, default rates, and loss severities (each of which may in turn incorporate various macro-economic assumptions, such as future housing prices, GDP growth rates, and unemployment rates). These assumptions are re-evaluated not less than quarterly. Changes in projected cash flows may result in prospective changes in the yield/interest income recognized on such securities based on the updated expected future cash flows. For each loan purchased with the expectation that both interest and principal will be paid in full, the Company generally amortizes or accretes any premium or discount over the life of the loan utilizing the effective interest method. However, based on current information and market developments, the Company re-assesses the collectibility of interest and principal, and generally designates a loan as in non-accrual status either when any payments have become 90 or more days past due, or when, in the opinion of management, it is probable that the Company will be unable to collect either interest or principal in full. Once a loan is designated as in non-accrual status, as long as principal is still expected to be collectible in full, interest payments are recorded as interest income only when received (i.e., under the cash basis method); accruals of interest income are only resumed when the loan becomes contractually current and performance is demonstrated to be resumed. However, if principal is not expected to be collectible in full, the cost recovery method is used (i.e., no interest income is recognized, and all payments received—whether contractually interest or principal—are applied to cost). Certain of the Company's debt securities and loans, at the date of acquisition, have experienced or are expected to experience more-than-insignificant deterioration in credit quality since origination. Consistent with the Company's application of the principles of ASU 2016-13, if at the date of acquisition for a particular asset the Company projects a significant difference between contractual cash flows and expected cash flows, it establishes an initial estimate for credit losses as an upward adjustment to the acquisition cost of the asset for the purpose of calculating interest income using the effective yield method. In estimating future cash flows on the Company's debt securities, there are a number of assumptions that are subject to significant uncertainties and contingencies, including, in the case of MBS, assumptions relating to prepayment rates, default rates, loan loss severities, and loan repurchases. These estimates require the use of a significant amount of judgment.
Investments in Unconsolidated Entities	Investments in unconsolidated entities : The Company has made and may in the future make non-controlling equity investments in various entities, such as loan originators. Such investments are generally in the form of preferred and/or common equity, or membership interests. In certain cases, the Company can exercise significant influence over the entity (e.g. by having representation on the entity's board of directors) but the requirements for consolidation under ASC 810 are not met; in such cases the Company is required to account for such equity investments under ASC 323-10, Investments—Equity Method and Joint Ventures
REO	Real Estate Owned "REO" : When the Company obtains possession of real property in connection with a foreclosure or similar action, the Company de-recognizes the associated mortgage loan according to ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure ("ASU 2014-04"). Under the provisions of ASU 2014-04, the Company is deemed to have received physical possession of real estate property collateralizing a mortgage loan when it obtains legal title to the property upon completion of a foreclosure or when the borrower conveys all interest in the property to it through a deed in lieu of foreclosure or similar legal agreement. The Company's initial cost basis in REO is equal to the fair value of the real estate associated with the foreclosed mortgage loan, less expected costs to sell. REO valuations are reflected at the lower of cost or fair value. The fair value of such REO is typically based on management's estimates which generally use information including general economic data, BPOs, recent sales, property appraisals, and bids, and takes into account the expected costs to sell the property. REO recorded at fair value on a non-recurring basis are classified as Level 3.
Securities Sold Short	Securities Sold Short: The Company may purchase or engage in short sales of U.S. Treasury securities and sovereign debt to mitigate the potential impact of changes in interest rates and/or foreign exchange rates on the performance of its portfolio. When the Company sells securities short, it typically satisfies its security delivery settlement obligation by borrowing or purchasing the security sold short from the same or a different counterparty. When borrowing a security sold short from a counterparty, the Company generally is required to deliver cash or securities to such counterparty as collateral for the Company's obligation to return the borrowed security. The Company has chosen to elect the FVO pursuant to ASC 825 for its securities sold short. Electing the FVO allows the Company to record changes in fair value in the Consolidated Statement of Operations, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all securities activities will be recorded in a similar manner. As such, securities sold short are recorded at fair value on the Consolidated Balance Sheet and the period change in fair value is recorded in current period earnings on the Consolidated Statement of Operations as a component of Unrealized gains (losses) on securities and loans, net. A realized gain or loss will be recognized upon the termination of a short sale if the market price is less or greater than the original sale price. Such realized gain or loss is recorded on the Company's Consolidated Statement of Operations in Realized gains (losses) on securities and loans, net.
Financial Derivatives	Financial Derivatives: The Company enters into various types of financial derivatives subject to its investment guidelines, which include restrictions associated with maintaining qualification as a REIT. The Company's financial derivatives are predominantly subject to bilateral master trade agreements or clearing in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the "Dodd-Frank Act." The Company may be required to deliver or receive cash or securities as collateral upon entering into derivative transactions. In addition, changes in the value of derivative transactions may require the Company or the counterparty to post or receive additional collateral. In the case of cleared derivatives, the clearinghouse becomes the Company's counterparty and a futures commission merchant acts as an intermediary between the Company and the clearinghouse with respect to all facets of the related transaction, including the posting and receipt of required collateral. Cash collateral received by the Company is included in Due to brokers, on the Consolidated Balance Sheet. Conversely, cash collateral posted by the Company is included in Due from brokers, on the Consolidated Balance Sheet. The types of derivatives primarily utilized by the Company are swaps, TBAs, futures, options, and forwards. Swaps : The Company may enter into various types of swaps, including interest rate swaps, credit default swaps, and total return swaps. The primary risk associated with the Company's interest rate swap activity is interest rate risk. The primary risk associated with the Company's credit default swaps and total return swaps is credit risk. The Company is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Primarily to help mitigate interest rate risk, the Company enters into interest rate swaps. Interest rate swaps are contractual agreements whereby one party pays a floating interest rate on a notional principal amount and receives a fixed-rate payment on the same notional principal, or vice versa, for a fixed period of time. Interest rate swaps change in value with movements in interest rates. The Company also enters into interest rate swaps whereby the Company pays one floating rate and receives a different floating rate, or "basis swaps." The Company enters into credit default swaps. A credit default swap is a contract under which one party agrees to compensate another party for the financial loss associated with the occurrence of a "credit event" in relation to a "reference amount" or notional value of a "reference asset" (usually a bond, loan, or an index or basket of bonds or loans). The definition of a credit event may vary from contract to contract. A credit event may occur (i) when the reference asset (or underlying asset, in the case of a reference asset that is an index or basket) fails to make scheduled principal or interest payments to its holders, (ii) with respect to credit default swaps referencing mortgage/asset-backed securities and indices, when the reference asset (or underlying asset, in the case of a reference asset that is an index or basket) is downgraded below a certain rating level, or (iii) with respect to credit default swaps referencing corporate entities and indices, upon the bankruptcy of the obligor of the reference asset (or underlying obligor, in the case of a reference asset that is an index). The Company typically writes (sells) protection to take a "long" position with respect to the underlying reference assets, or purchases (buys) protection to take a "short" position with respect to the underlying reference assets or to hedge exposure to other investment holdings. The Company enters into total return swaps in order to take a "long" or "short" position with respect to an underlying reference asset. The Company is subject to market price volatility of the underlying reference asset. A total return swap involves commitments to pay interest in exchange for a market-linked return based on a notional value. To the extent that the total return of the corporate debt, security, group of securities or index underlying the transaction exceeds or falls short of the offsetting interest obligation, the Company will receive a payment from or make a payment to the counterparty. Swaps change in value with movements in interest rates, credit quality, or total return of the reference securities. During the term of swap contracts, changes in value are recognized as unrealized gains or losses on the Consolidated Statement of Operations. When a contract is terminated, the Company realizes a gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Company's basis in the contract, if any. Periodic payments or receipts required by swap agreements are recorded as unrealized gains or losses when accrued and realized gains or losses when received or paid. Upfront payments paid and/or received by the Company to open swap contracts are recorded as an asset and/or liability on the Consolidated Balance Sheet and are recorded as a realized gain or loss on the termination date. TBA Securities : The Company transacts in the forward settling TBA market. A TBA position is a forward contract for the purchase ("long position") or sale ("short position") of Agency RMBS at a predetermined price, face amount, issuer, coupon, and maturity on an agreed-upon future delivery date. For each TBA contract and delivery month, a uniform settlement date for all market participants is determined by the Securities Industry and Financial Markets Association. The specific Agency RMBS to be delivered into the contract at the settlement date are not known at the time of the transaction. The Company usually does not take delivery of TBAs, but rather enters into offsetting transactions and settles the associated receivable and payable balances with its counterparties. The Company uses TBAs to mitigate interest rate risk, usually by taking short positions. The Company also invests in TBAs as a means of acquiring additional exposure to Agency RMBS, or for speculative purposes, including holding long positions. TBAs are accounted for by the Company as financial derivatives. The difference between the forward contract price and the market value of the TBA position as of the reporting date is included in Unrealized gains (losses) on financial derivatives, net, on the Consolidated Statement of Operations. Futures Contracts : A futures contract is an exchange-traded agreement to buy or sell an asset for a set price on a future date. The Company enters into Eurodollar and/or U.S. Treasury security futures contracts to hedge its interest rate risk. The Company may also enter into various other futures contracts, including equity index futures and foreign currency futures. Initial margin deposits are made upon entering into futures contracts and can generally be either in the form of cash or securities. During the period the futures contract is open, changes in the value of the contract are recognized as unrealized gains or losses by marking-to-market to reflect the current market value of the contract. Variation margin payments are made or received periodically, depending upon whether unrealized losses or gains are incurred. When the contract is closed, the Company records a realized gain or loss equal to the difference between the proceeds of the closing transaction and the Company's basis in the contract. Options : The Company may purchase or write put or call options contracts or enter into swaptions. The Company enters into options contracts typically to help mitigate overall market, credit, or interest rate risk depending on the type of options contract. However, the Company also enters into options contracts from time to time for speculative purposes. When the Company purchases an options contract, the option asset is initially recorded at an amount equal to the premium paid, if any, and is subsequently marked-to-market. Premiums paid for purchasing options contracts that expire unexercised are recognized on the expiration date as realized losses. If an options contract is exercised, the premium paid is subtracted from the proceeds of the sale or added to the cost of the purchase to determine whether the Company has realized a gain or loss on the related transaction. When the Company writes an options contract, the option liability is initially recorded at an amount equal to the premium received, if any, and is subsequently marked-to-market. Premiums received for writing options contracts that expire unexercised are recognized on the expiration date as realized gains. If an options contract is exercised, the premium received is subtracted from the cost of the purchase or added to the proceeds of the sale to determine whether the Company has realized a gain or loss on the related investment transaction. When the Company enters into a closing transaction, the Company will realize a gain or loss depending upon whether the amount from the closing transaction is greater or less than the premiums paid or received. The Company may also enter into options contracts that contain forward-settling premiums. In this case, no money is exchanged upfront. Instead, the agreed-upon premium is paid by the buyer upon expiration of the option, regardless of whether or not the option is exercised. Forward Currency Contracts : A forward currency contract is an agreement between two parties to purchase or sell a specific quantity of currency with the delivery and settlement at a specific future date and exchange rate. During the period the forward currency contract is open, changes in the value of the contract are recognized as unrealized gains or losses. When the contract is settled, the Company records a realized gain or loss equal to the difference between the proceeds of the closing transaction and the Company's basis in the contract.
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash and cash equivalents include cash and short term investments with original maturities of three months or less at the date of acquisition. Cash and cash equivalents typically include amounts held in interest bearing overnight accounts and amounts held in money market funds, and these balances generally exceed insured limits. The Company holds its cash at institutions that it believes to be highly creditworthy. Restricted cash represents cash that the Company can use only for specific purposes. See Note 18 for further discussion of restricted cash balances.
Transfers of Financial Assets	Transfers of Financial Assets : The Company enters into transactions whereby it transfers financial assets to third parties. Upon such a transfer of financial assets, the Company will sometimes retain or acquire interests in the related assets. The Company evaluates transferred assets pursuant to ASC 860-10, Transfers of Financial Assets , or "ASC 860-10," which requires that a determination be made as to whether a transferor has surrendered control over transferred financial assets. That determination must consider the transferor's continuing involvement in the transferred financial asset, including all arrangements or agreements made contemporaneously with, or in contemplation of, the transfer, even if they were not entered into at the time of the transfer. When a transfer of financial assets does not qualify as a sale, ASC 860-10 requires the transfer to be accounted for as a secured borrowing with a pledge of collateral. ASC 860-10 is a standard that requires the Company to exercise significant judgment in determining whether a transaction should be recorded as a "sale" or a "financing."
Variable Interest Entities	Variable Interest Entities: VIEs are entities in which: (i) the equity investors do not have the characteristics of a controlling financial interest, or (ii) there is insufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties. Consolidation of a VIE is required by the entity that is deemed to be the primary beneficiary of the VIE. The Company evaluates all of its interests in VIEs for consolidation under ASC 810. The primary beneficiary is generally the party with both (i) the power to direct the activities of the VIE that most significantly impact its economic performance, and (ii) the obligation to absorb losses and the right to receive benefits from the VIE which could be potentially significant to the VIE. When the Company has an interest in an entity that has been determined to be a VIE, the Company assesses whether it is deemed to be the primary beneficiary of the VIE. The Company will only consolidate a VIE for which it has concluded it is the primary beneficiary. To assess whether the Company has the power to direct the activities of a VIE that most significantly impact the VIE's economic performance, the Company considers all facts and circumstances, including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes (i) identifying the activities that most significantly impact the VIE's economic performance; and (ii) identifying which party, if any, has power over those activities. To assess whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, it considers all of its economic interests, including debt and/or equity investments, as well as other arrangements deemed to be variable interests in the VIE. These assessments to determine whether the Company is the primary beneficiary require significant judgment. In instances where the Company and its related parties have interests in a VIE, the Company considers whether there is a single party in the related party group that meets the criteria to be deemed the primary beneficiary. If one party within the related party group meets such criteria, that reporting entity would be deemed to be the primary beneficiary of the VIE and no further analysis is needed. If no party within the related party group on its own meets the criteria to be deemed the primary beneficiary, but the related party group as a whole meets such criteria, the determination of the primary beneficiary within the related party group requires significant judgment. The Company performs analysis, which is based upon qualitative as well as quantitative factors, such as the relationship of the VIE to each of the members of the related party group, as well as the significance of the VIE's activities to those members, with the objective of determining which party is most closely associated with the VIE. The Company performs ongoing reassessments of (i) whether any entities previously evaluated have become VIEs, based on certain events, and therefore subject to assessment to determine whether consolidation is appropriate, and (ii) whether changes in the facts and circumstances regarding the Company's involvement with a VIE causes its consolidation conclusion regarding the VIE to change. See Note 9 and Note 13 for further information on the Company's consolidated VIEs. The Company's maximum amount at risk is generally limited to the Company's investment in the VIE. The Company is generally not contractually required to provide and has not provided any form of financial support to the VIEs. The Company holds beneficial interests in certain securitization trusts that are considered VIEs. The beneficial interests in these securitization trusts are represented by certificates issued by the trusts. The securitization trusts have been structured as pass-through entities that receive principal and interest payments on the underlying collateral and distribute those payments to the certificate holders, which include both third-party investors and the Company. The certificates held by the Company typically include some or all of the most subordinated tranches. The assets held by the trusts are restricted in that they can only be used to fulfill the obligations of the related trust. In certain cases, the design and structure of the securitization trust is such that the Company effectively retains control of the assets as well as the activities that most significantly impact the economic performance of the trust. In such cases, the Company is determined to be the primary beneficiary, and the Company consolidates the trust and all intercompany transactions are eliminated in consolidation. In cases where the Company does not effectively retain control of the assets of, or have the power to direct the activities that most significantly impact the economic performance of, the related trust, it does not consolidate the trust. See Note 10 for further discussion of the Company's securitization trusts.
Offering Costs/Underwriters' Discount	Offering Costs/Underwriters' Discount :
Debt Issuance Costs	Debt Issuance Costs: Debt issuance costs associated with debt for which the Company has elected the FVO are expensed at the issuance of the debt, and are included in Investment related expenses—Other on the Consolidated Statement of Operations. Costs associated with the issuance of debt for which the Company has not elected the FVO are deferred and amortized over the life of the debt, which approximates the effective interest rate method, and are included in Interest expense on the Consolidated Statement of Operations. Deferred debt issuance costs are presented on the Consolidated Balance Sheet as a direct deduction from the related debt liability, unless such deferred debt issuance costs are associated with borrowing facilities that are expected to have a future benefit, such as giving the Company the ability to access additional borrowings over the contractual term of the debt, in which case such deferred debt issuance costs are included in Other assets on the Consolidated Balance Sheet. Debt issuance costs include legal and accounting fees, purchasers' or underwriters' discount, as well as other fees associated with the cost of the issuance of the related debt.
Expenses	Expenses: Expenses are recognized as incurred on the Consolidated Statement of Operations.
Investment Related Expenses	Investment Related Expenses: Investment related expenses consist of expenses directly related to specific financial instruments. Such expenses generally include dividend expense on common stock sold short, servicing fees and corporate and escrow advances on mortgage and consumer loans, and various other expenses and fees related directly to the Company's financial instruments. The Company has elected the FVO for its investments, and as a result all investment related expenses are expensed as incurred and included in Investment related expenses on the Consolidated Statement of Operations.
Investment Related Receivables [Policy Text Block]	Investment Related Receivables: Investment related receivables on the Company's Consolidated Balance Sheet includes receivables for securities sold and interest and principal receivable on securities and loans.
LTIP Units	Long Term Incentive Plan Units : Long term incentive plan units of the Operating Partnership ("OP LTIP Units") have been issued to certain Ellington personnel dedicated or partially dedicated to the Company, certain of the Company's directors, as well as the Manager. Costs associated with OP LTIP Units issued to dedicated or partially dedicated personnel, or to the Company's directors, are measured as of the grant date based on the Company's closing stock price on the New York Stock Exchange and are amortized over the vesting period in accordance with ASC 718-10, Compensation—Stock Compensation . The vesting periods for OP LTIP Units are typically one year from issuance for non-executive directors, and are typically one year to two years from issuance for dedicated or partially dedicated personnel.
Non-controlling interest	Non-controlling interests : Non-controlling interests include interests in the Operating Partnership represented by units convertible into shares of the Company's common stock ("Convertible Non-controlling Interests"). Convertible Non-controlling Interests include both the OP LTIP Units and those common units ("OP Units") of the Operating Partnership not held by the Company (collectively, the "Convertible Non-controlling Interest Units"). Non-controlling interests also include the interests of joint venture partners in certain of our consolidated subsidiaries. The joint venture partners' interests are not convertible into shares of the Company's common stock. The Company adjusts the Convertible Non-controlling Interests to align their carrying value with their share of total outstanding Operating Partnership units, including both the OP Units held by the Company and the Convertible Non-controlling Interests. Any such adjustments are reflected in Adjustment to non-controlling interests, on the Consolidated Statement of Changes in Equity. See Note 15 for further discussion of non-controlling interests.
Dividends	Dividends: Dividends payable on shares of common stock and Convertible Non-controlling Interest Units are recorded on the declaration date.
Shares Repurchased	Shares Repurchased: Shares of common stock that are repurchased by the Company subsequent to issuance are immediately retired upon settlement and decrease the total number of shares of common stock issued and outstanding. The cost of such repurchases is charged against Additional paid-in-capital on the Company's Consolidated Balance Sheet.
Earnings Per Share ("EPS")	Earnings Per Share ("EPS"): Basic EPS is computed using the two class method by dividing net income (loss) after adjusting for the impact of Convertible Non-controlling Interests which are participating securities, by the weighted average number of shares of common stock outstanding calculated including Convertible Non-controlling Interests. Because the Company's Convertible Non-controlling Interests are participating securities, they are included in the calculation of both basic and diluted EPS.
Foreign Currency	Foreign Currency: The functional currency of the Company is U.S. dollars. Assets and liabilities denominated in foreign currencies are remeasured into U.S. dollars at current exchange rates at the following dates: (i) assets, liabilities, and unrealized gains/losses—at the valuation date; and (ii) income, expenses, and realized gains/losses—at the accrual/transaction date. The Company isolates the portion of realized and change in unrealized gain (loss) resulting from changes in foreign currency exchange rates on investments and financial derivatives from the fluctuations arising from changes in fair value of investments and financial derivatives held. Changes in realized and change in unrealized gain (loss) due to foreign currency are included in Other, net, on the Consolidated Statement of Operations. The Company's reporting currency is U.S. Dollars. If the Company has investments in unconsolidated entities that have a functional currency other than U.S. Dollars, the fair value is translated to U.S. dollars using the current exchange rate at the valuation date. The cumulative translation adjustment, if any, associated with the Company's investments in unconsolidated entities is recorded in accumulated other comprehensive income (loss), a component of consolidated stockholders' equity.
Income Taxes	Income Taxes: The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Code. As a REIT, the Company is generally not subject to corporate-level federal and state income tax on net income it distributes to its stockholders within the prescribed timeframes. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including distributing at least 90% of its annual taxable income to stockholders. Even if the Company qualifies as a REIT, it may be subject to certain federal, state, local and foreign taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. If the Company fails to qualify as a REIT, and does not qualify for certain statutory relief provisions, it 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 the Company fails to qualify as a REIT. As a REIT, if the Company fails to distribute in any calendar year (subject to specific timing rules for certain dividends paid in January) at least the sum of (i) 85% of its ordinary income for such year, (ii) 95% of its capital gain net income for such year, and (iii) any undistributed taxable income from the prior year, the Company would be subject to a non-deductible 4% excise tax on the excess of such required distribution over the sum of (i) the amounts actually distributed and (ii) the amounts of income retained and on which the Company has paid corporate income tax. The Company elected to treat certain domestic and foreign subsidiaries as TRSs, and may in the future elect to treat other current or future subsidiaries as TRSs. In general, a TRS may hold assets and engage in activities that the Company cannot hold or engage in directly and generally may engage in any real estate or non-real estate-related business. A domestic TRS may, but is not required to, declare dividends to the Company; such dividends will be included in the Company's taxable income/(loss) and may necessitate a distribution to the Company's stockholders. Conversely, if the Company retains earnings at the level of a domestic TRS, such earnings will increase the book equity of the consolidated entity. A domestic TRS is subject to U.S. federal, state, and local corporate income taxes. The Company has elected and may elect in the future to treat certain of its foreign corporate subsidiaries as TRSs and, accordingly, taxable income generated by these TRSs may not be subject to U.S. federal, state, and local corporate income taxation, but generally will be included in the Company's income on a current basis as Subpart F income, whether or not distributed. However, certain of the Company's foreign subsidiaries may be subject to income taxes in the relevant foreign jurisdictions. The Company's financial results are generally not expected to reflect provisions for current or deferred income taxes, except for any activities conducted through one or more TRSs that are subject to corporate income taxation. The Company follows the authoritative guidance on accounting for and disclosure of uncertainty on tax positions, which requires management to determine whether a tax position of the Company is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For uncertain tax positions, the tax benefit to be recognized is measured as the largest amount of benefit that is more than 50% likely to be realized upon ultimate settlement. The Company did not have any unrecognized tax benefits resulting from tax positions related to the current period or its open tax years. In the normal course of business, the Company may be subject to examination by federal, state, local, and foreign jurisdictions, where applicable, for the current period and its open tax years. The Company may take positions with respect to certain tax issues which depend on legal interpretation of facts or applicable tax regulations. Should the relevant tax regulators successfully challenge any of such positions, the Company might be found to have a tax liability that has not been recorded in the accompanying consolidated financial statements. Also, management's conclusions regarding the authoritative guidance may be subject to review and adjustment at a later date based on changing tax laws, regulations, and interpretations thereof. The Company recognizes interest and penalties, if any, related to uncertain tax positions, as income tax expense included in Income tax expense (benefit) on the Consolidated Statement of Operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements : In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform—Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"), which provides optional guidance for a limited period meant to ease the potential burden in accounting for, or recognizing the effects of, reform to LIBOR and certain other reference rates. The standard became effective for all entities beginning on March 12, 2020 and may be elected over time. However, ASU 2020-04 is only applicable to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform, and that were entered into or evaluated prior to January 1, 2023. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2021-01"), which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications apply to derivatives that are affected by the reform to LIBOR. The amendments in this update became effective immediately for all entities. ASU 2021-01 provides increased clarity as the Company continues to evaluate the transition of reference rates, and it is currently evaluating the impact that the adoption of ASU 2020-04 would have on the consolidated financial statements.
Financial Assets Sold under Agreement to Repurchase [Member]
Assets Sold under Agreements to Repurchase [Line Items]
Repurchase and Resale Agreements	Repurchase Agreements: The Company enters into repurchase agreements with third-party broker-dealers whereby it sells securities under agreements to be repurchased at an agreed-upon price and date. The Company accounts for repurchase agreements as collateralized borrowings, with the initial sale price representing the amount borrowed, and with the future repurchase price consisting of the amount borrowed plus interest, at the implied interest rate of the repurchase agreement, on the amount borrowed over the term of the repurchase agreement. The interest rate on a repurchase agreement is based on competitive rates (or competitive market spreads, in the case of agreements with floating interest rates) at the time such agreement is entered into. When the Company enters into a repurchase agreement, the lender establishes and maintains an account containing cash and/or securities having a value not less than the repurchase price, including accrued interest, of the repurchase agreement. Repurchase agreements are carried at their contractual amounts, which approximate fair value as the debt is short-term in nature.
Securities Purchased under Agreements to Resell [Member]
Assets Sold under Agreements to Repurchase [Line Items]
Repurchase and Resale Agreements	Reverse Repurchase Agreements : The Company enters into reverse repurchase agreement transactions whereby it purchases securities under agreements to resell at an agreed-upon price and date. In general, securities received pursuant to reverse repurchase agreements are delivered to counterparties of short sale transactions. The interest rate on a reverse repurchase agreement is based on competitive rates (or competitive market spreads, in the case of agreements with floating interest rates) at the time such agreement is entered into. Assets held pursuant to reverse repurchase agreements are reflected as assets on the Consolidated Balance Sheet. Reverse repurchase agreements are carried at their contractual amounts, which approximates fair value due to their short-term nature. Repurchase and reverse repurchase agreements that are conducted with the same counterparty may be reported on a net basis if they meet the requirements of ASC 210-20, Balance Sheet Offsetting . There are no repurchase and reverse repurchase agreements reported on a net basis in the Company's consolidated financial statements.

Movements in the value of credit default swap transactions may require the Company or the counterparty to post or receive collateral. Amounts due or owed under credit derivative contracts with an International Swaps and Derivatives Association, or "ISDA," counterparty may be offset against amounts due or owed on other credit derivative contracts with the same ISDA counterparty. As a result, the notional value of written credit derivatives involving a particular underlying reference asset or index has been reduced (but not below zero) by the notional value of any contracts where the Company has purchased credit protection on the same reference asset or index with the same ISDA counterparty.
