Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Basis of Presentation	Note 1. Organization and Basis of Presentation Arlington Asset Investment Corp. (“Arlington Asset”) and its consolidated subsidiaries (unless the context otherwise provides, collectively, the “Company”) is an investment firm that focuses on acquiring and holding a levered portfolio of mortgage investments generally consisting of agency mortgage-backed securities (“MBS”) and mortgage credit investments. The Company’s agency MBS include residential mortgage pass-through certificates for which the principal and interest payments are guaranteed by either a U.S. government sponsored enterprise (“GSE”), such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or by a U.S. government agency, such as the Government National Mortgage Association (“Ginnie Mae”). The Company’s mortgage credit investments may include investments in mortgage loans secured by either residential or commercial real property, MBS collateralized by residential or commercial mortgage loans (“non-agency MBS”), and loans or securities collateralized by mortgage servicing rights (“MSR”). The principal and interest of the Company’s mortgage credit investments are not guaranteed by a GSE or a U.S. government agency. Arlington Asset is a Virginia corporation that is internally managed and does not have an external investment advisor. We intend to elect to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) upon filing our tax return for our taxable year ended December 31, 2019. As a REIT, the Company will be required to distribute annually 90% of its REIT taxable income (subject to certain adjustments). So long as the Company continues to qualify as a REIT, it will generally not be subject to U.S. Federal or state corporate income taxes on its taxable income that it distributes to its shareholders on a timely basis. At present, it is the Company’s intention to distribute 100% of its taxable income, although the Company will not be required to do so. The Company intends to make distributions of its taxable income within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year The unaudited interim consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. The Company’s unaudited interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The Company’s consolidated financial statements include the accounts of Arlington Asset and all other entities in which the Company has a controlling financial interest. All intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements. Although the Company bases these estimates and assumptions on historical experience and all other reasonably available information that the Company believes to be relevant under the circumstances, such estimates frequently require management to exercise significant subjective judgment about matters that are inherently uncertain. Actual results may differ from these estimates materially. Certain amounts in the consolidated financial statements and notes for prior periods have been reclassified to conform to the current year’s presentation. These reclassifications had no impact on the previously reported net income, total assets or total liabilities.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Cash Equivalents Cash equivalents include demand deposits with banks, money market accounts and highly liquid investments with original maturities of three months or less. As of June 30, 2020 and December 31, 2019, approximately 98% and 97%, respectively, of the Company’s cash equivalents were invested in money market funds that invest primarily in U.S. Treasuries and other securities backed by the U.S. government. Investment Security Purchases and Sales Purchases and sales of investment securities are recorded on the settlement date of the transfer unless the trade qualifies as a “regular-way” trade and the associated commitment qualifies for an exemption from the accounting guidance applicable to derivative instruments. A regular-way trade is an investment security purchase or sale transaction that is expected to settle within the period of time following the trade date that is prevalent or traditional for that specific type of security. Any amounts payable or receivable for unsettled security trades are recorded as “sold securities receivable” or “purchased securities payable” in the consolidated balance sheets. Interest Income Recognition for Investments in Agency MBS The Company recognizes interest income for its investments in agency MBS by applying the “interest method” permitted by GAAP, whereby purchase premiums and discounts are amortized and accreted, respectively, as an adjustment to contractual interest income accrued at each security’s stated coupon rate. The interest method is applied at the individual security level based upon each security’s effective interest rate. The Company calculates each security’s effective interest rate at the time of purchase by solving for the discount rate that equates the present value of that security's remaining contractual cash flows (assuming no principal prepayments) to its purchase price. Because each security’s effective interest rate does not reflect an estimate of future prepayments, the Company refers to this manner of applying the interest method as the “contractual effective interest method.” When applying the contractual effective interest method to its investments in agency MBS, as principal prepayments occur, a proportional amount of the unamortized premium or discount is recognized in interest income such that the contractual effective interest rate on the remaining security balance is unaffected. Interest Income Recognition for Investments in Mortgage Credit Securities The Company recognizes interest income for its investments in mortgage credit securities by applying the prospective level-yield methodology required by GAAP for securitized financial assets that are either not of high credit quality at the time of acquisition or can be contractually prepaid or otherwise settled in such a way that the Company would not recover substantially all of its recorded investment. The amount of periodic interest income recognized is determined by applying the security’s effective interest rate to its amortized cost basis (or “reference amount”). At the time of acquisition, the security’s effective interest rate is calculated by solving for the single discount rate that equates the present value of the Company’s best estimate of the amount and timing of the cash flows expected to be collected from the security to its purchase price. To prepare its best estimate of cash flows expected to be collected, the Company develops a number of assumptions about the future performance of the pool of mortgage loans that serve as collateral for its investment, including assumptions about the timing and amount of prepayments and credit losses. In each subsequent quarterly reporting period, the amount and timing of cash flows expected to be collected from the security are re-estimated based upon current information and events. The following table provides a description of how periodic changes in the estimate of cash flows expected to be collected affect interest income recognition prospectively for investments in mortgage credit securities: Scenario: Effect on Interest Income Recognition for Investments in Mortgage Credit Securities: A positive change in cash flows occurs. Actual cash flows exceed prior estimates and/or a positive change occurs in the estimate of expected remaining cash flows. A revised effective interest rate is calculated and applied prospectively such that the positive change in cash flows is recognized as incremental interest income over the remaining life of the security. The amount of periodic interest income recognized over the remaining life of the security will be reduced accordingly. Specifically, if an adverse change in cash flows occurs for a security that is impaired (that is, its fair value is less than its reference amount), the reference amount to which the security’s existing effective interest rate will be prospectively applied will be reduced to the present value of cash flows expected to be collected, discounted at the security’s existing effective interest rate. If an adverse change in cash flows occurs for a security that is not impaired, the security’s effective interest rate will be reduced accordingly and applied on a prospective basis.

Recent Accounting Pronouncements The following table provides a brief description of recently issued accounting pronouncements and their actual or expected effect on the Company’s consolidated financial statements: Standard Description Date of Adoption Effect on the Consolidated Financial Statements Recently Adopted Accounting Guidance ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 606) The amendments in this update require financial assets measured at amortized cost as well as available-for-sale debt securities to be measured for impairment on the basis of the net amount expected to be collected. Credit losses are to be recognized through an allowance for credit losses, which differs from the direct write-down of the amortized cost basis previously required for other-than-temporary impairments of investments in debt securities. This update also makes substantial changes to the manner in which interest income is to be recognized for financial assets acquired with a more-than-insignificant amount of credit deterioration since origination. This update does not affect the accounting for financial assets that are measured at fair value on a recurring basis with changes in fair value reflected in net income. January 1, 2020 Substantially all of the Company’s investments in financial assets are measured at fair value on a recurring basis with changes in fair value reflected in net income. Accordingly, the adoption of ASU No. 2016-13 did not have an effect on the Company’s consolidated financial statements. Recently Issued Accounting Guidance Not Yet Adopted Standard Description Date of Adoption Effect on the Consolidated Financial Statements ASU No. 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting The amendments in this update provide optional practical expedients and exceptions for applying GAAP to the modification of receivables, debt, or lease contracts as well as cash flow and fair value hedge accounting relationships that reference a rate, such as LIBOR, that is expected to be discontinued because of reference rate reform. The practical expedients and exceptions provided by the update are effective from March 12, 2020 through December 31, 2022. Not yet adopted. To date, the Company has not made any modifications to contracts due to reference rate reform. The Company has not elected to apply hedge accounting for financial reporting purposes. The Company does not currently expect the adoption of ASU No. 2020-04 to have an effect on its consolidated financial statements.

Borrowings

Debt Disclosure [Abstract]
Borrowings	Note 6. Borrowings Repurchase Agreements The Company finances the purchase of mortgage investments through repurchase agreements, which are accounted for as collateralized borrowing arrangements. In a repurchase transaction, the Company sells a mortgage investment to a counterparty under a master repurchase agreement in exchange for cash and concurrently agrees to repurchase the same asset at a future date in an amount equal to the cash initially exchanged plus an agreed-upon amount of interest. Mortgage investments sold under agreements to repurchase remain on the Company’s consolidated balance sheets because the Company maintains effective control over such assets throughout the duration of the arrangement. Throughout the contractual term of a repurchase agreement, the Company recognizes a “repurchase agreement” liability on its consolidated balance sheets to reflect the obligation to repay to the counterparty the proceeds received upon the initial transfer of the mortgage investment. The difference between the proceeds received by the Company upon the initial transfer of the mortgage investment and the contractually agreed-upon repurchase price is recognized as interest expense ratably over the term of the repurchase arrangement. Amounts borrowed pursuant to repurchase agreements are equal in value to a specified percentage of the fair value of the pledged collateral. The Company retains beneficial ownership of the pledged collateral throughout the term of the repurchase agreement. The counterparty to the repurchase agreements may require that the Company pledge additional securities or cash as additional collateral to secure borrowings when the value of the collateral declines. The Company’s MBS repurchase agreement arrangements generally carry a fixed rate of interest and are short-term in nature with contract durations generally ranging from 30 to 60 days, but may be as short as one day or as long as one year. The Company’s mortgage loan repurchase agreement arrangement has a maturity date of May 12, 2021 and an interest rate that resets monthly at a rate equal to one-month LIBOR plus 2.00% with an interest rate floor of 3.00%. Under the terms of the Company’s mortgage loan repurchase agreement, the Company may request extensions of the maturity date of the agreement for up to 364 days, subject to the lender’s approval. As of June 30, 2020 and December 31, 2019, the Company had no amount at risk with a single repurchase agreement counterparty or lender greater than 10% of equity. The following table provides information regarding the Company’s outstanding repurchase agreement borrowings as of the dates indicated: June 30, 2020 December 31, 2019 Agency MBS repurchase financing: Repurchase agreements outstanding $ 395,377 $ 3,560,139 Agency MBS collateral, at fair value (1) 415,475 3,741,399 Net amount (2) 20,098 181,260 Weighted-average rate 0.22 % 2.10 % Weighted-average term to maturity 14.0 days 23.7 days Non-agency MBS repurchase financing: Repurchase agreements outstanding $ — $ 21,098 MBS collateral, at fair value (2) — 30,747 Net amount (2) — 9,649 Weighted-average rate — 3.11 % Weighted-average term to maturity — 8.1 days Mortgage loans repurchase financing: Repurchase agreements outstanding $ 31,500 $ — Mortgage loans collateral, at fair value 44,549 — Net amount (2) 13,049 — Weighted-average rate 3.00 % — Weighted-average term to maturity 316 days — Total mortgage investments repurchase financing: Repurchase agreements outstanding $ 426,877 $ 3,581,237 Mortgage investments collateral, at fair value 460,024 3,772,146 Net amount (2) 33,147 190,909 Weighted-average rate 0.43 % 2.11 % Weighted-average term to maturity 36.3 days 23.6 days (1) As of June 30, 2020 and December 31, 2019, includes $28,563 and $71,284, respectively, at sale price of unsettled agency MBS sale commitments which are included in the line item “sold securities receivable” in the accompanying consolidated balance sheets.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 7. Derivative Instruments In the normal course of its operations, the Company is a party to financial instruments that are accounted for as derivative instruments. Derivative instruments are recorded at fair value as either “derivative assets” or “derivative liabilities” in the consolidated balance sheets, with all periodic changes in fair value reflected as a component of “investment gain (loss), net” in the consolidated statements of comprehensive income. Cash receipts or payments related to derivative instruments are classified as investing activities within the consolidated statements of cash flows. Types and Uses of Derivative Instruments Interest Rate Hedging Instruments The Company is party to interest rate hedging instruments that are intended to economically hedge changes, attributable to changes in benchmark interest rates, in certain MBS fair values and future interest cash flows on the Company’s short-term financing arrangements. Interest rate hedging instruments include centrally cleared interest rate swaps, exchange-traded instruments, such as U.S. Treasury note futures, Eurodollar futures, interest rate swap futures and options on futures, and non-exchange-traded instruments such as options on agency MBS. While the Company uses its interest rate hedging instruments to economically hedge a portion of its interest rate risk, it has not designated such contracts as hedging instruments for financial reporting purposes. The Company exchanges cash “variation margin” with the counterparties to its interest rate hedging instruments at least on a daily basis based upon daily changes in fair value as measured by the Chicago Mercantile Exchange (“CME”), the central clearinghouse through which those instruments are cleared. In addition, the CME requires market participants to deposit and maintain an “initial margin” amount which is determined by the CME and is generally intended to be set at a level sufficient to protect the CME from the maximum estimated single-day price movement in that market participant’s contracts . However, futures commission merchants may require “initial margin” in excess of the CME’s requirement Receivables recognized for the right to reclaim cash initial margin posted in respect of interest rate hedging instruments are included in the line item “deposits” in the accompanying consolidated balance sheets. The daily exchange of variation margin associated with a centrally cleared or exchange-traded hedging instrument is legally characterized as the daily settlement of the instrument itself, as opposed to a pledge of collateral. Accordingly, the Company accounts for the daily receipt or payment of variation margin associated with its interest rate swaps and futures as a direct reduction to the carrying value of the derivative asset or liability, respectively. The carrying amount of interest rate swaps and futures reflected in the Company’s consolidated balance sheets is equal to the unsettled fair value of such instruments; because variation margin is exchanged on a one-day lag, the unsettled fair value of such instruments generally represents the change in fair value that occurred on the last day of the reporting period. To-Be-Announced Agency MBS Transactions, Including “Dollar Rolls” In addition to interest rate hedging instruments that are used for interest rate risk management, the Company is a party to derivative instruments that economically serve as investments, such as forward commitments to purchase fixed-rate “pass-through” agency MBS on a non-specified pool basis, which are known as to-be-announced (“TBA”) securities. A TBA security is a forward commitment for the purchase or sale of a fixed-rate agency MBS at a predetermined price, face amount, issuer, coupon, and stated maturity for settlement on an agreed upon future date. The specific agency MBS that will be delivered to satisfy the TBA trade is not known at the inception of the trade. The specific agency MBS to be delivered is determined 48 hours prior to the settlement date. The Company accounts for TBA securities as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA commitment that its settlement will result in physical delivery of the underlying agency MBS, or the individual TBA commitment will not settle in the shortest time period possible. The Company’s agency MBS investment portfolio includes net purchase (or “net long”) positions in TBA securities, which are primarily the result of executing sequential series of “dollar roll” transactions. The Company executes dollar roll transactions as a means of investing in and financing non-specified fixed-rate agency MBS. Such transactions involve effectively delaying (or “rolling”) the settlement of a forward purchase of a TBA agency MBS by entering into an offsetting sale with the same counterparty prior to the settlement date, net settling the “paired-off” positions in cash, and contemporaneously entering, with the same counterparty, another forward purchase of a TBA agency MBS of the same characteristics for a later settlement date. TBA securities purchased for a forward settlement month are generally priced at a discount relative to TBA securities sold for settlement in the current month. This discount, often referred to as the dollar roll “price drop,” reflects compensation for the net interest income (interest income less financing costs) that is foregone as a result of relinquishing beneficial ownership of the MBS for the duration of the dollar roll (also known as “dollar roll income”). By executing a sequential series of dollar roll transactions, the Company is able to create the economic experience of investing in an agency MBS, financed with a repurchase agreement, over a period of time. Forward purchases and sales of TBA securities are accounted for as derivative instruments in the Company’s financial statements. Accordingly, dollar roll income is recognized as a component of “investment gain (loss), net” along with all other periodic changes in the fair value of TBA commitments. In addition to transacting in net long positions in TBA securities for investment purposes, the Company may also, from time to time, transact in net sale (or “net short”) positions in TBA securities for the purpose of economically hedging a portion of the sensitivity of the fair value of the Company’s investments in agency MBS to changes in interest rates. In addition to TBA transactions, the Company may, from time to time, enter into commitments to purchase or sell specified agency MBS that do not qualify as regular-way security trades. Such commitments are also accounted for as derivative instruments. Under the terms of commitments to purchase or sell TBAs or specified agency MBS, the daily exchange of variation margin may occur based on changes in the fair value of the underlying agency MBS if a party to the transaction demands it. Receivables recognized for the right to reclaim cash collateral posted by the Company in respect of agency MBS purchase or sale commitments is included in the line item “deposits” in the accompanying consolidated balance sheets. Liabilities recognized for the obligation to return cash collateral received by the Company in respect of agency MBS purchase or sale commitments is included in the line item “other liabilities” in the accompanying consolidated balance sheets.

Offsetting of Financial Assets and Liabilities	Note 8. Offsetting of Financial Assets and Liabilities The agreements that govern certain of the Company’s derivative instruments and collateralized short-term financing arrangements provide for a right of setoff in the event of default or bankruptcy with respect to either party to such transactions. The Company presents derivative assets and liabilities as well as collateralized short-term financing arrangements on a gross basis. Receivables recognized for the right to reclaim cash initial margin posted in respect of interest rate derivative instruments are included in the line item “deposits” in the accompanying consolidated balance sheets. The daily exchange of variation margin associated with a centrally cleared or exchange-traded derivative instrument is legally characterized as the daily settlement of the derivative instrument itself, as opposed to a pledge of collateral. Accordingly, the Company accounts for the daily receipt or payment of variation margin associated with its interest rate swaps and futures as a direct reduction to the carrying value of derivative asset or liability, respectively. The carrying amount of interest rate swaps and futures reflected in the Company’s consolidated balance sheets is equal to the unsettled fair value of such instruments; because variation margin is exchanged on a one-day lag, the unsettled fair value of such instruments generally represents the change in fair value that occurred on the last day of the reporting period.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 9. Fair Value Measurements Fair Value of Financial Instruments The accounting principles related to fair value measurements define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company at the measurement date; Level 2 Inputs - Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and Level 3 Inputs - Unobservable inputs for the asset or liability, including significant judgments made by the Company about the assumptions that a market participant would use. The Company measures the fair value of the following assets and liabilities: Mortgage investments Agency MBS - The Company’s investments in agency MBS are classified within Level 2 of the fair value hierarchy. Inputs to fair value measurements of the Company’s investments in agency MBS include price estimates obtained from third-party pricing services. In determining fair value, third-party pricing services use a market approach. The inputs used in the fair value measurements performed by the third-party pricing services are based upon readily observable transactions for securities with similar characteristics (such as issuer/guarantor, coupon rate, stated maturity, and collateral pool characteristics) occurring on the measurement date. The Company makes inquiries of the third-party pricing sources and review their documented valuation methodologies to understand the significant inputs and assumptions used to determine prices. The Company reviews the various third-party fair value estimates and performs procedures to validate their reasonableness, including comparison to recent trading activity for similar securities and an overall review for consistency with market conditions observed as of the measurement date. Mortgage credit securities - Most of the Company’s investments in mortgage credit securities are classified within Level 2 of the fair value hierarchy. Inputs to fair value measurements of the Company’s investments in mortgage credit securities include quoted prices for similar assets in recent market transactions and estimates obtained from third-party pricing sources including pricing services and dealers. In determining fair value, third-party pricing sources use a market approach. The inputs used in the fair value measurements performed by third-party pricing sources are based upon observable transactions for mortgage credit securities with similar characteristics. The Company reviews the third-party fair value estimates and performs procedures to validate their reasonableness, including comparisons to recent trading activity observed for similar securities as well as an internally derived discounted future cash flow measurement. The Company’s non-agency MBS investment secured by a pool of business-purpose residential mortgage loans of the amount and timing of the cash flows expected to be collected from the security over its expected remaining life o prepare the estimate of cash flows expected to be collected, the Company uses significant judgment to develop assumptions about the future performance of the pool of business-purpose residential mortgage loans that serve as collateral, including assumptions about the timing and amount of credit losses and prepayments June 30, 2020 Annualized default rate 7.3 % Loss-given-default 40.0 % Discount rate 10.1 % Loans – The Company’s investments in loans are classified within Level 3 of the fair value hierarchy. To measure the fair value of its loan investments, the Company uses an income approach by preparing an estimate of the present value of the expected future cash flows of each loan over its expected remaining life, discounted at a current market rate . The significant unobservable inputs to the fair value measurement of the Company’s loan investment s are the estimated remaining life of the loan and the discount rate, which is based on current market yields and interest rate spreads for a similar loan. As of June 30, 2020 , the estimated remaining life of the Company’s commercial mortgage loan investment was 2 years and the discount rate used to measure the present value of estimated future cash flows was 6.9 %. As of December 31, 2019, the fair value of the Company’s mortgage loan investment was its price of purchase, which occurred on the measurement date . Derivative instruments Exchange-traded derivative instruments - Exchange-traded derivative instruments, which include U.S. Treasury note futures, Eurodollar futures, interest rate swap futures, and options on futures, are classified within Level 1 of the fair value hierarchy as they are measured using quoted prices for identical instruments in liquid markets. Interest rate swaps - Interest rate swaps are classified within Level 2 of the fair value hierarchy. The fair values of the Company’s centrally cleared interest rate swaps are measured using the daily valuations reported by the clearinghouse through which the instrument was cleared. In performing its end-of-day valuations, the clearinghouse constructs forward interest rate curves (for example, three-month LIBOR forward rates) from its specific observations of that day’s trading activity. The clearinghouse uses the applicable forward interest rate curve to develop a market-based forecast of future remaining contractually required cash flows for each interest rate swap. Each market-based cash flow forecast is then discounted using the overnight index swap rate curve (sourced from the Federal Reserve Bank of New York) to determine a net present value amount which represents the instrument’s fair value. Forward-settling purchases and sales of TBA securities – Forward-settling purchases and sales of TBA securities are classified within Level 2 of the fair value hierarchy. The fair value of each forward-settling TBA contract is measured using price estimates obtained from a third-party pricing service, which are based upon readily observable transaction prices occurring on the measurement date for forward-settling contracts to buy or sell TBA securities with the same guarantor, contractual maturity, and coupon rate for delivery on the same forward settlement date as the commitment under measurement. Other Long-term unsecured debt - As of June 30, 2020 and December 31, 2019, the carrying value of the Company’s long-term unsecured debt was $74,022 and $74,328, respectively, net of unamortized debt issuance costs, and consists of Senior Notes and trust preferred debt issued by the Company. The Company’s estimate of the fair value of long-term unsecured debt is $68,127 and $70,429 as of June 30, 2020 and December 31, 2019, respectively. The Company’s Senior Notes, which are publicly traded on the New York Stock Exchange, are classified within Level 1 of the fair value hierarchy. Trust preferred debt is classified within Level 2 of the fair value hierarchy as the fair value is estimated based on the quoted prices of the Company’s publicly traded Senior Notes. Investments in equity securities of publicly-traded companies – As of June 30, 2020, the Company had investments in equity securities of publicly-traded companies at fair value of $11,084, which is included in the line item “other assets” in the accompanying consolidated balance sheets. The Company held no investments in equity securities of publicly-traded companies at December 31, 2019. Investments in publicly traded stock are classified within Level 1 of the fair value hierarchy as their fair value is measured based on u nadjusted quoted prices in active exchange markets for identical assets. Investments in equity securities of non-public companies and investment funds – As of June 30, 2020 and December 31, 2019, the Company had investments in equity securities and investment funds measured at fair value of $7,333 and $6,375, respectively, which are included in the line item “other assets” in the accompanying consolidated balance sheets. Investments in equity securities of non-public companies and investment funds are classified within Level 3 of the fair value hierarchy. The fair values of the Company’s investments in equity securities of non-public companies and investment funds are not readily determinable. Accordingly, the Company estimates fair value by estimating the enterprise value of the investee which it then allocates to the investee’s securities in the order of their preference relative to one another. To estimate the enterprise value of the investee, the Company uses traditional valuation methodologies based on income and market approaches, including the consideration of recent investments in, or tender offers for, the equity securities of the investee, a discounted cash flow analysis and a comparable guideline public company valuation. The primary unobservable inputs used in estimating the fair value of an equity security of a non-public company include (i) a stock price to net asset multiple for similar public companies that is applied to the entity’s net assets, (ii) a discount factor for lack of marketability and control, and (iii) a cost of equity discount rate, used to discount to present value the equity cash flows available for distribution and the terminal value of the entity. As of June 30, 2020, the stock price to net asset multiple for similar public companies, the discount factor for lack of marketability and control, and the cost of equity discount rate used as inputs were 95 percent, 10 percent, and 15 percent, respectively. As of December 31, 2019, the stock price to net asset multiple for similar public companies, the discount factor for lack of marketability and control, and the cost of equity discount rate used as inputs were 95 percent, 9 percent, and 12 percent, respectively. For its investments in investment funds, the Company estimates fair value based upon the investee’s net asset value per share. Financial assets and liabilities for which carrying value approximates fair value - Cash and cash equivalents, deposits, receivables, repurchase agreements, payables, and other assets (aside from those previously discussed) and liabilities are generally reflected in the consolidated balance sheets at their cost, which, due to the short-term nature of these instruments and their limited inherent credit risk, approximates fair value. Fair Value Hierarchy Financial Instruments Measured at Fair Value on a Recurring Basis The following tables set forth financial instruments measured at fair value by level within the fair value hierarchy as of June 30, 2020 and December 31, 2019. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Income Tax Disclosure [Abstract]
Income Taxes	Note 10. Income Taxes The Company intends to elect to be taxed as a REIT under the Internal Revenue Code upon filing its tax return for its taxable year ended December 31, 2019. As a REIT, the Company will be required to distribute annually 90% of its REIT taxable income. So long as the Company continues to qualify as a REIT, it will generally not be subject to U.S. Federal or state corporate income taxes on its taxable income to the extent that it distributes all of its annual taxable income to its shareholders on a timely basis. At present, it is the Company’s intention to distribute 100% of its taxable income, although the Company will not be required to do so. The Company intends to make distributions of its taxable income within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year. For the Company’s tax years ended December 31, 2018 and earlier, the Company was taxed as a C corporation for U.S. federal tax purposes. As of June 30, 2020, the Company had estimated net operating loss (“NOL”) carryforwards of $14,588 that can be used to offset future taxable ordinary income. The Company’s NOL carryforwards expire in 2028. As of June 30, 2020, the Company had estimated net capital loss (“NCL”) carryforwards of $247,333 that can be used to offset future net capital gains. The scheduled expirations of the Company’s NCL carryforwards are $66,385 in 2020, $66,862 in 2021, $3,763 in 2022 and $110,323 in 2023. As of June 30, 2020, the Company also had $170,411 of deferred net losses from interest rate hedges for income tax purposes. Through December 31, 2017, the Company was subject to federal alternative minimum tax (“AMT”) on its taxable income and gains that were not offset by its NOL and NCL carryforwards with any AMT credit carryforwards available to offset future regular tax liabilities. As part of the Tax Cuts and Jobs Act of 2017, the corporate AMT was repealed for tax years beginning after December 31, 2017 with any AMT credit carryforward after that date continuing to be available to offset a taxpayer’s future regular tax liability. In addition, for tax years beginning in 2018, 2019 and 2020, to the extent that AMT credit carryforwards exceed the regular tax liability, 50% of the excess AMT credit carryforwards would be refundable upon the filing of the income tax return for that year with any remaining AMT credit carryforwards fully refundable upon the filing of the 2021 income tax return. As part of the Coronavirus Aid, Relief, and Economic Security Act of 2020 (the “Cares Act”), the timing of the refunding of the full amount of excess AMT credit carryforwards was accelerated so that it can now be refunded immediately. As a result, the Company filed a request for a full refund of its remaining excess AMT credit that it received in July 2020. As of June 30, 2020 and December 31, 2019, the Company had an AMT credit carryforward of $4,566, included as a receivable in “other assets” on the accompanying consolidated balance sheets. The Company recognizes uncertain tax positions in the financial statements only when it is more-likely-than-not that the position will be sustained upon examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured On May 29, 2018, the Company received an assessment of $9,380 from Arlington County, Virginia for a business, professional and occupation license (“BPOL”) tax for 2018. The BPOL tax is a local privilege tax on a business’ gross receipts for conducting business activities subject to licensure within a county in Virginia. The Company had not been assessed or paid any such BPOL tax prior to 2018. On June 28, 2018, the Company filed an administrative appeal with Arlington County. On August 1, 2018, the Company received a denial of its administrative appeal from Arlington County and, subsequently, the Company filed an administrative appeal with the Tax Commissioner of Virginia (the “Tax Commissioner”) on September 27, 2018. On June 21, 2019, the Company received a determination from the Tax Commissioner stating that he believes the Company is engaged in a licensable privilege subject to the BPOL tax. The Tax Commissioner requested that Arlington County revise its initial BPOL tax assessment to exclude certain gross receipts from its tax calculation. On August 21, 2019, the Company received a revised 2018 BPOL tax assessment of $ 488 , including interest charges, as well as a 2019 BPOL tax assessment of $ 471 from Arlington County both of which the Company paid on September 3, 2019. On September 30, 2019, the Company relocated its corporate headquarters from Arlington County to Fairfax County, Virginia. As a result, the Company received a partial refund of its 2019 BPOL tax of $ 118 from Arlington County while also recognizing a partial year 2019 BPOL tax assessment of $ 54 to Fairfax County. For the year ended December 31, 2019, the Company recognized an expense of $ 892 in “other general and administrative expense” which represents the 2018 and 2019 BPOL tax (and associated interest). BPOL tax for the 2017 year remains subject to examination by Arlington County, although the county has previously informally indicated that it did not intend to pursue assessments for that year at such time.

During the three and six months ended June 30, 2020, there were no issuances of preferred stock under the Series B preferred equity distribution agreement. The following table provides information about the issuances of preferred stock under the Series B preferred equity distribution agreements for the period indicated: Series B Preferred Stock Issuances Year Ended December 31, 2019 Shares issued 3,444 Weighted average public offering price $ 22.39 Net proceeds (1) $ 76 (1) As of June 30, 2020, the Company had 1,645,961 shares of Series B Preferred stock available for sale under the preferred equity distribution agreement. Shareholder Rights Agreement On June 1, 2009, the Board of Directors approved a shareholder rights agreement (“Rights Plan”) and the Company’s shareholders approved the Rights Plan at its annual meeting of shareholders on June 2, 2010. On April 9, 2018, the Board of Directors approved a first amendment to the Rights Plan (“First Amendment”) to extend the term for an additional three years and the Company’s shareholders approved the First Amendment at its annual meeting of shareholders on June 14, 2018. Under the terms of the Rights Plan, in general, if a person or group acquires or commences a tender or exchange offer for beneficial ownership of 4.9% or more of the outstanding shares of our Class A common stock upon a determination by our Board of Directors (an “Acquiring Person”), all of our other Class A and Class B common shareholders will have the right to purchase securities from us at a discount to such securities’ fair market value, thus causing substantial dilution to the Acquiring Person. The Board of Directors adopted the Rights Plan in an effort to protect against a possible limitation on the Company’s ability to use its NOL carryforwards, NCL carryforwards, and built-in losses under Sections 382 and 383 of the Internal Revenue Code. The Company’s ability to use its NOLs, NCLs and built-in losses would be limited if it experienced an “ownership change” under Section 382 of the Internal Revenue Code. In general, an “ownership change” would occur if there is a cumulative change in the ownership of the Company’s common stock of more than 50% by one or more “5% shareholders” during a three-year period. The Rights Plan was adopted to dissuade any person or group from acquiring 4.9% or more of the Company’s outstanding Class A common stock, each, an Acquiring Person, without the approval of the Board of Directors and triggering an “ownership change” as defined by Section 382. The Rights Plan, as amended, and any outstanding rights will expire at the earliest of (i) June 4, 2022, (ii) the time at which the rights are redeemed or exchanged pursuant to the Rights Plan, (iii) the repeal of Section 382 and 383 of the Internal Revenue Code or any successor statute if the Board of Directors determines that the Rights Plan is no longer necessary for the preservation of the applicable tax benefits, or (iv) the beginning of a taxable year to which the Board of Directors determines that no applicable tax benefits may be carried forward.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2020
Cash Equivalents	Cash Equivalents Cash equivalents include demand deposits with banks, money market accounts and highly liquid investments with original maturities of three months or less. As of June 30, 2020 and December 31, 2019, approximately 98% and 97%, respectively, of the Company’s cash equivalents were invested in money market funds that invest primarily in U.S. Treasuries and other securities backed by the U.S. government.
Investment Security Purchases and Sales	Investment Security Purchases and Sales Purchases and sales of investment securities are recorded on the settlement date of the transfer unless the trade qualifies as a “regular-way” trade and the associated commitment qualifies for an exemption from the accounting guidance applicable to derivative instruments. A regular-way trade is an investment security purchase or sale transaction that is expected to settle within the period of time following the trade date that is prevalent or traditional for that specific type of security. Any amounts payable or receivable for unsettled security trades are recorded as “sold securities receivable” or “purchased securities payable” in the consolidated balance sheets.
Interest Income Recognition for Investments in Agency MBS	Interest Income Recognition for Investments in Agency MBS The Company recognizes interest income for its investments in agency MBS by applying the “interest method” permitted by GAAP, whereby purchase premiums and discounts are amortized and accreted, respectively, as an adjustment to contractual interest income accrued at each security’s stated coupon rate. The interest method is applied at the individual security level based upon each security’s effective interest rate. The Company calculates each security’s effective interest rate at the time of purchase by solving for the discount rate that equates the present value of that security's remaining contractual cash flows (assuming no principal prepayments) to its purchase price. Because each security’s effective interest rate does not reflect an estimate of future prepayments, the Company refers to this manner of applying the interest method as the “contractual effective interest method.” When applying the contractual effective interest method to its investments in agency MBS, as principal prepayments occur, a proportional amount of the unamortized premium or discount is recognized in interest income such that the contractual effective interest rate on the remaining security balance is unaffected.
Interest Income Recognition for Investments in Mortgage Credit Securities	Interest Income Recognition for Investments in Mortgage Credit Securities The Company recognizes interest income for its investments in mortgage credit securities by applying the prospective level-yield methodology required by GAAP for securitized financial assets that are either not of high credit quality at the time of acquisition or can be contractually prepaid or otherwise settled in such a way that the Company would not recover substantially all of its recorded investment. The amount of periodic interest income recognized is determined by applying the security’s effective interest rate to its amortized cost basis (or “reference amount”). At the time of acquisition, the security’s effective interest rate is calculated by solving for the single discount rate that equates the present value of the Company’s best estimate of the amount and timing of the cash flows expected to be collected from the security to its purchase price. To prepare its best estimate of cash flows expected to be collected, the Company develops a number of assumptions about the future performance of the pool of mortgage loans that serve as collateral for its investment, including assumptions about the timing and amount of prepayments and credit losses. In each subsequent quarterly reporting period, the amount and timing of cash flows expected to be collected from the security are re-estimated based upon current information and events. The following table provides a description of how periodic changes in the estimate of cash flows expected to be collected affect interest income recognition prospectively for investments in mortgage credit securities: Scenario: Effect on Interest Income Recognition for Investments in Mortgage Credit Securities: A positive change in cash flows occurs. Actual cash flows exceed prior estimates and/or a positive change occurs in the estimate of expected remaining cash flows. A revised effective interest rate is calculated and applied prospectively such that the positive change in cash flows is recognized as incremental interest income over the remaining life of the security. The amount of periodic interest income recognized over the remaining life of the security will be reduced accordingly. Specifically, if an adverse change in cash flows occurs for a security that is impaired (that is, its fair value is less than its reference amount), the reference amount to which the security’s existing effective interest rate will be prospectively applied will be reduced to the present value of cash flows expected to be collected, discounted at the security’s existing effective interest rate. If an adverse change in cash flows occurs for a security that is not impaired, the security’s effective interest rate will be reduced accordingly and applied on a prospective basis. An adverse change in cash flows occurs. Actual cash flows fall short of prior estimates and/or an adverse change occurs in the estimate of expected remaining cash flows.
Other Significant Accounting Policies	Other Significant Accounting Policies Certain of the Company’s other significant accounting policies are summarized in the following notes: Investments in agency MBS, subsequent measurement Note 3 Investments in mortgage credit securities, subsequent measurement Investments in loans Borrowings Note 4 Note 5 Note 6 To-be-announced agency MBS transactions, including “dollar rolls” Note 7 Derivative instruments Note 7 Balance sheet offsetting Note 8 Fair value measurements Note 9 Refer to the Company’s 2019 Annual Report on Form 10-K for a complete inventory and summary of the Company’s significant accounting policies.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following table provides a brief description of recently issued accounting pronouncements and their actual or expected effect on the Company’s consolidated financial statements: Standard Description Date of Adoption Effect on the Consolidated Financial Statements Recently Adopted Accounting Guidance ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 606) The amendments in this update require financial assets measured at amortized cost as well as available-for-sale debt securities to be measured for impairment on the basis of the net amount expected to be collected. Credit losses are to be recognized through an allowance for credit losses, which differs from the direct write-down of the amortized cost basis previously required for other-than-temporary impairments of investments in debt securities. This update also makes substantial changes to the manner in which interest income is to be recognized for financial assets acquired with a more-than-insignificant amount of credit deterioration since origination. This update does not affect the accounting for financial assets that are measured at fair value on a recurring basis with changes in fair value reflected in net income. January 1, 2020 Substantially all of the Company’s investments in financial assets are measured at fair value on a recurring basis with changes in fair value reflected in net income. Accordingly, the adoption of ASU No. 2016-13 did not have an effect on the Company’s consolidated financial statements. Recently Issued Accounting Guidance Not Yet Adopted Standard Description Date of Adoption Effect on the Consolidated Financial Statements ASU No. 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting The amendments in this update provide optional practical expedients and exceptions for applying GAAP to the modification of receivables, debt, or lease contracts as well as cash flow and fair value hedge accounting relationships that reference a rate, such as LIBOR, that is expected to be discontinued because of reference rate reform. The practical expedients and exceptions provided by the update are effective from March 12, 2020 through December 31, 2022. Not yet adopted. To date, the Company has not made any modifications to contracts due to reference rate reform. The Company has not elected to apply hedge accounting for financial reporting purposes. The Company does not currently expect the adoption of ASU No. 2020-04 to have an effect on its consolidated financial statements.
Repurchase Agreements	The Company finances the purchase of mortgage investments through repurchase agreements, which are accounted for as collateralized borrowing arrangements. In a repurchase transaction, the Company sells a mortgage investment to a counterparty under a master repurchase agreement in exchange for cash and concurrently agrees to repurchase the same asset at a future date in an amount equal to the cash initially exchanged plus an agreed-upon amount of interest. Mortgage investments sold under agreements to repurchase remain on the Company’s consolidated balance sheets because the Company maintains effective control over such assets throughout the duration of the arrangement. Throughout the contractual term of a repurchase agreement, the Company recognizes a “repurchase agreement” liability on its consolidated balance sheets to reflect the obligation to repay to the counterparty the proceeds received upon the initial transfer of the mortgage investment. The difference between the proceeds received by the Company upon the initial transfer of the mortgage investment and the contractually agreed-upon repurchase price is recognized as interest expense ratably over the term of the repurchase arrangement.
Derivative Instruments	In the normal course of its operations, the Company is a party to financial instruments that are accounted for as derivative instruments. Derivative instruments are recorded at fair value as either “derivative assets” or “derivative liabilities” in the consolidated balance sheets, with all periodic changes in fair value reflected as a component of “investment gain (loss), net” in the consolidated statements of comprehensive income. Cash receipts or payments related to derivative instruments are classified as investing activities within the consolidated statements of cash flows. In addition to interest rate hedging instruments that are used for interest rate risk management, the Company is a party to derivative instruments that economically serve as investments, such as forward commitments to purchase fixed-rate “pass-through” agency MBS on a non-specified pool basis, which are known as to-be-announced (“TBA”) securities. A TBA security is a forward commitment for the purchase or sale of a fixed-rate agency MBS at a predetermined price, face amount, issuer, coupon, and stated maturity for settlement on an agreed upon future date. The specific agency MBS that will be delivered to satisfy the TBA trade is not known at the inception of the trade. The specific agency MBS to be delivered is determined 48 hours prior to the settlement date. The Company accounts for TBA securities as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA commitment that its settlement will result in physical delivery of the underlying agency MBS, or the individual TBA commitment will not settle in the shortest time period possible.
Derivatives, Offsetting of Financial Assets and Liabilities	The agreements that govern certain of the Company’s derivative instruments and collateralized short-term financing arrangements provide for a right of setoff in the event of default or bankruptcy with respect to either party to such transactions. The Company presents derivative assets and liabilities as well as collateralized short-term financing arrangements on a gross basis. Receivables recognized for the right to reclaim cash initial margin posted in respect of interest rate derivative instruments are included in the line item “deposits” in the accompanying consolidated balance sheets. The daily exchange of variation margin associated with a centrally cleared or exchange-traded derivative instrument is legally characterized as the daily settlement of the derivative instrument itself, as opposed to a pledge of collateral. Accordingly, the Company accounts for the daily receipt or payment of variation margin associated with its interest rate swaps and futures as a direct reduction to the carrying value of derivative asset or liability, respectively. The carrying amount of interest rate swaps and futures reflected in the Company’s consolidated balance sheets is equal to the unsettled fair value of such instruments; because variation margin is exchanged on a one-day lag, the unsettled fair value of such instruments generally represents the change in fair value that occurred on the last day of the reporting period.
Fair Value of Financial Instruments	The accounting principles related to fair value measurements define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Financial Accounting Standards Board Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company at the measurement date; Level 2 Inputs - Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and Level 3 Inputs - Unobservable inputs for the asset or liability, including significant judgments made by the Company about the assumptions that a market participant would use. The Company measures the fair value of the following assets and liabilities:
