Organization and Nature of Business Operations	Note 1 - Organization and Nature of Business Operations References to "we," "us," "our," or the "Company" are to ARMOUR Residential REIT, Inc. ("ARMOUR") and its subsidiaries. References to "ACM" are to ARMOUR Capital Management LP, a Delaware limited partnership. ARMOUR owns a 10.8% equity interest in BUCKLER Securities LLC ("BUCKLER"). BUCKLER is a Delaware limited liability company and a FINRA-regulated broker-dealer, controlled by ACM and certain executive officers of ARMOUR. Refer to the Glossary of Terms for definitions of capitalized terms and abbreviations used in this report. U.S. dollar amounts are presented in thousands, except per share amounts or as otherwise noted. ARMOUR is an externally managed Maryland corporation incorporated in 2008. The Company is managed by ACM, an investment advisor registered with the Securities and Exchange Commission (the "SEC"), (see Note 8 - Commitments and Contingencies and Note 14 - Related Party Transactions). We have elected to be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). Our qualification as a REIT depends on our ability to meet, on a continuing basis, various complex requirements under the Code relating to, among other things, the sources of our gross income, the composition and values of our assets, our distribution levels and the concentration of ownership of our capital stock. We believe that we are organized in conformity with the requirements for qualification as a REIT under the Code and our manner of operations enables us to meet the requirements for taxation as a REIT for federal income tax purposes. As a REIT, we will generally not be subject to federal income tax on the REIT taxable income that we currently distribute to our stockholders. If we fail to qualify as a REIT in any taxable year and do not qualify for certain statutory relief provisions, we will be subject to federal income tax at regular corporate rates. Even if we qualify as a REIT for U.S. federal income tax purposes, we may still be subject to some federal, state and local taxes on our income. At June 30, 2023 and December 31, 2022, we invested in mortgage backed securities ("MBS"), issued or guaranteed by a United States ("U.S.") Government-sponsored entity ("GSE"), such as the Federal National Mortgage Association ("Fannie Mae"), the Federal Home Loan Mortgage Corporation ("Freddie Mac"), or a government agency such as Government National Mortgage Administration ("Ginnie Mae") (collectively, "Agency Securities"). Our Agency Securities consist primarily of fixed rate loans. The remaining are either backed by hybrid adjustable rate or adjustable rate loans. From time to time we have also invested in Credit Risk and Non-Agency Securities, Interest-Only Securities, U.S. Treasury Securities and money market instruments.

Basis of Presentation and Consolidation	Note 2 - Basis of Presentation and Consolidation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the SEC. Accordingly, the condensed financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2023. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2022. The unaudited consolidated financial statements include the accounts of ARMOUR Residential REIT, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated. The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the accompanying condensed consolidated financial statements include the valuation of MBS, including an assessment of the allowance for credit losses, and derivative instruments.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 3 - Summary of Significant Accounting Policies Cash Cash includes cash on deposit with financial institutions. We may maintain deposits in federally insured financial institutions in excess of federally insured limits. However, management believes we are not exposed to significant credit risk due to the financial position and creditworthiness of the depository institutions in which those deposits are held. Cash Collateral Posted To/By Counterparties Cash collateral posted to/by counterparties represents cash posted by us to counterparties or posted by counterparties to us as collateral. Cash collateral posted to/by counterparties may include collateral for interest rate swap contracts, interest rate swaptions, basis swap contracts, futures contracts, repurchase agreements on our MBS and our Agency Securities purchased or sold on a to-be-announced basis ("TBA Agency Securities"). Investments in Securities, at Fair Value Our investments in securities are generally classified as either available for sale or trading securities. Management determines the appropriate classifications of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date. Trading Securities are reported at their estimated fair values with gains and losses included in Other Income (Loss) as a component of the consolidated statements of operations and comprehensive income (loss). Available for Sale Securities represented investments that we intended to hold for extended periods of time and were reported at their estimated fair values with unrealized gains and losses excluded from earnings and reported as part of comprehensive income (loss). During the first quarter of 2023, we sold the remaining balance of our Available for Sale Securities which resulted in a realized loss of $(7,471). Receivables and Payables for Unsettled Sales and Purchases We account for purchases and sales of securities on the trade date, including purchases and sales for forward settlement. Receivables and payables for unsettled trades represent the agreed trade price multiplied by the outstanding balance of the securities at the balance sheet date. Accrued Interest Receivable and Payable Accrued interest receivable includes interest accrued between payment dates on securities and interest on unsettled sales of securities. Accrued interest payable includes interest on unsettled purchases of securities and interest on repurchase agreements. At certain times, we may have interest payable on U.S. Treasury Securities sold short. Repurchase Agreements, net We finance the acquisition of the majority of our MBS through the use of repurchase agreements. Our repurchase agreements are secured by our MBS and bear interest rates that have moved in close relationship to the Federal Funds Effective Rate ("Fed Funds Rate") and the Secured Overnight Funding Rate ("SOFR"). Under these repurchase agreements, we sell MBS to a lender and agree to repurchase the same MBS in the future for a price that is higher than the original sales price. The difference between the sales price that we receive and the repurchase price that we pay represents interest paid to the lender, which accrues over the life of the repurchase agreement. A repurchase agreement operates as a financing arrangement under which we pledge our MBS as collateral to secure a loan which is equal in value to a specified percentage of the estimated fair value of the pledged collateral. We retain beneficial ownership of the pledged collateral. At the maturity of a repurchase agreement, we are required to repay the loan and concurrently receive back our pledged collateral from the lender or, with the consent of the lender, we may renew such agreement at the then prevailing interest rate. The repurchase agreements may require us to pledge additional assets to the lender in the event the estimated fair value of the existing pledged collateral declines. In addition to the repurchase agreement financing discussed above, at certain times, we have entered into reverse repurchase agreements with certain of our repurchase agreement counterparties. Under a typical reverse repurchase agreement, we purchase U.S. Treasury Securities from a borrower in exchange for cash and agree to sell the same securities in the future in exchange for a price that is higher than the original purchase price. The difference between the purchase price originally paid and the sale price represents interest received from the borrower. Reverse repurchase agreement receivables and repurchase agreement liabilities are presented net when they meet certain criteria, including being with the same counterparty, being governed by the same master repurchase agreement ("MRA"), settlement through the same brokerage or clearing account and maturing on the same day. At June 30, 2023 and December 31, 2022, we had $512,500 and $704,276, respectively, in reverse repurchase agreements which are recorded in repurchase agreements, net on our consolidated balance sheet. Obligations to Return Securities Received as Collateral, at Fair Value We also sell to third parties the U.S. Treasury Securities received as collateral for reverse repurchase agreements and recognize the resulting obligation to return said U.S. Treasury Securities as a liability on our consolidated balance sheet. Interest is recorded on the repurchase agreements, reverse repurchase agreements and U.S. Treasury Securities on an accrual basis and presented as net interest expense. Both parties to the transaction have the right to make daily margin calls based on changes in the fair value of the collateral received and/or pledged. We had obligations to return securities received as collateral associated with our reverse repurchase agreements as of June 30, 2023 and December 31, 2022 of $497,188 ($99,438 of which were with BUCKLER) and $502,656 ($100,531 of which were with BUCKLER), respectively. Derivatives, at Fair Value We recognize all derivatives individually as either assets or liabilities at fair value on our consolidated balance sheets. All changes in the fair values of our derivatives are reflected in our consolidated statements of operations and comprehensive income (loss). We designate derivatives as hedges for tax purposes and any unrealized derivative gains or losses would not affect our distributable net taxable income. These transactions may include interest rate swap contracts, interest rate swaptions, basis swap contracts and futures contracts. We also may utilize forward contracts for the purchase or sale of TBA Agency Securities. We account for TBA Agency Securities as derivative instruments if it is reasonably possible that we will not take or make physical delivery of the Agency Security upon settlement of the contract. We account for TBA dollar roll transactions as a series of derivative transactions. We may also purchase and sell TBA Agency Securities as a means of investing in and financing Agency Securities (thereby increasing our “at risk” leverage) or as a means of disposing of or reducing our exposure to Agency Securities (thereby reducing our “at risk” leverage). We agree to purchase or sell, for future delivery, Agency Securities with certain principal and interest terms and certain types of collateral, but the particular Agency Securities to be delivered are not identified until shortly before the TBA settlement date. We may also choose, prior to settlement, to move the settlement of these securities out to a later date by entering into an offsetting short or long position (referred to as a “pair off”), net settling the paired off positions for cash, and simultaneously purchasing or selling a similar TBA Agency Security for a later settlement date. This transaction is commonly referred to as a “dollar roll.” When it is reasonably possible that we will pair off a TBA Agency Security, we account for that contract as a derivative. Impairment of Assets Impairment of available for sale securities was assessed at least on a quarterly basis and more frequently when economic or market concerns warranted such evaluation. An impairment was considered if we (1) intended to sell the available for sale securities, or (2) believed it was more likely than not that we were required to sell the securities before recovery (for example, because of liquidity requirements or contractual obligations) and a credit impairment existed where fair value was less than amortized cost. Impairment losses recognized established a new cost basis for the related available for sale securities. Revenue Recognition Interest income is earned and recognized on Agency Securities based on their unpaid principal amounts and their contractual terms. Recognition of interest income commences on the settlement date of the purchase transaction and continues through the settlement date of the sale transaction. Premiums and discounts associated with the purchase of Multi-Family MBS, which are generally not subject to prepayment, are amortized or accreted into interest income over the contractual lives of the securities using a level yield method. Premiums and discounts associated with the purchase of other Agency Securities are amortized or accreted into interest income over the actual lives of the securities, reflecting actual prepayments as they occur. Purchase and sale transactions (including TBA Agency Securities) are recorded on the trade date to the extent it is probable that we will take or make timely physical delivery of the related securities. Gains or losses realized from sales of available for sale securities are reclassified into income from Comprehensive Income (Loss) and are determined using the specific identification method. Interest income on U.S. Treasury Securities is recognized based on their unpaid principal amounts and their contractual terms. Recognition of interest income commences on the settlement date of the purchase transaction and continues through the settlement date of the sale transaction. Comprehensive Income (Loss)

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 4 - Fair Value of Financial Instruments Our valuation techniques for financial instruments use observable and unobservable inputs. Observable inputs reflect readily obtainable data from third-party sources, while unobservable inputs reflect management’s market assumptions. The Accounting Standards Codification Topic No. 820, "Fair Value Measurement," classifies these inputs into the following hierarchy: Level 1 Inputs - Quoted prices for identical instruments in active markets. Level 2 Inputs - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Inputs - Prices determined using significant unobservable inputs. Unobservable inputs may be used in situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period). Unobservable inputs reflect management’s assumptions about the factors that market participants would use in pricing an asset or liability and would be based on the best information available. At the beginning of each quarter, we assess the assets and liabilities that are measured at fair value on a recurring basis to determine if any transfers between levels in the fair value hierarchy are needed. The following describes the valuation methodologies used for our assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy. Any transfers between levels are assumed to occur at the beginning of the reporting period. Investments in Securities Fair value for our investments in securities are based on obtaining a valuation for each security from third-party pricing services and/or dealer quotes. The third-party pricing services use common market pricing methods that may include pricing models that may incorporate such factors as coupons, prepayment speeds, spread to the Treasury curves and interest rate swap curves, duration, periodic and life caps and credit enhancement. If the fair value of a security is not available from the third-party pricing services or such data appears unreliable, we obtain pricing indications from up to three dealers who make markets in similar securities. Management reviews pricing used to ensure that current market conditions are properly reflected. This review includes, but is not limited to, comparisons of similar market transactions or alternative third-party pricing services, dealer pricing indications and comparisons to a third-party pricing model. Fair values obtained from the third-party pricing services for similar instruments are classified as Level 2 securities if the inputs to the pricing models used are consistent with the Level 2 definition. If quoted prices for a security are not reasonably available from the third-party pricing service, but dealer pricing indications are, the security will be classified as a Level 2 security. If neither is available, management will determine the fair value based on characteristics of the security that we receive from the issuer and based on available market information and classify it as a Level 3 security. U.S. Treasury Securities are classified as Level 1, as quoted unadjusted prices are available in active markets for identical assets. Derivatives The fair values of our interest rate swap contracts, interest rate swaptions and basis swap contracts are valued using information provided by third-party pricing services that incorporate common market pricing methods that may include current interest rate curves, forward interest rate curves and market spreads to interest rate curves and are classified as Level 2. We estimate the fair value of TBA Agency Securities based on similar methods used to value our Agency Securities and they are classified as Level 2. Management compares the pricing information received to dealer quotes to ensure that the current market conditions are properly reflected. Futures contracts are traded on the Chicago Mercantile Exchange ("CME") which requires the use of daily mark-to-market collateral and they are classified as Level 1. The following tables provide a summary of our assets and liabilities that are measured at fair value on a recurring basis at June 30, 2023 and December 31, 2022. June 30, 2023 Level 1 Level 2 Level 3 Balance Assets at Fair Value: Agency Securities $ — $ 11,176,635 $ — $ 11,176,635 Derivatives $ 11,252 $ 989,797 $ — $ 1,001,049 Liabilities at Fair Value: Derivatives $ 8,166 $ 3,442 $ — $ 11,608 December 31, 2022 Level 1 Level 2 Level 3 Balance Assets at Fair Value: Agency Securities $ — $ 8,198,591 $ — $ 8,198,591 Derivatives $ 94 $ 984,362 $ — $ 984,456 Liabilities at Fair Value: Derivatives $ 516 $ 12,500 $ — $ 13,016 There were no transfers of assets or liabilities between the levels of the fair value hierarchy during the six months ended June 30, 2023 or for the year ended December 31, 2022.

Investments in Securities	Note 5 - Investments in Securities As of June 30, 2023 and December 31, 2022, our securities portfolio consisted of $11,176,635 and $8,198,591 of investment securities, at fair value, respectively. We also had $100,734 and $777,469 of TBA Agency Securities, at fair value, which were reported at net carrying value of $(3,027) and $(11,797), respectively, at June 30, 2023 and December 31, 2022. TBA Securities are reported in Derivatives, at fair value on our consolidated balance sheets (see Note 7 - Derivatives). The net carrying value of our TBA Agency Securities represents the difference between the fair value of the underlying Agency Security in the TBA contract and the cost basis or the forward price to be paid or received for the underlying Agency Security. During the first quarter of 2023, we sold the remaining balance of our Available for Sale Securities which resulted in a realized loss of $(7,471).

The following tables represent the contractual repricing regarding our repurchase agreements to finance MBS purchases at June 30, 2023 and December 31, 2022.

Our repurchase agreements require that we maintain adequate pledged collateral. A decline in the value of the MBS pledged as collateral for borrowings under repurchase agreements could result in the counterparties demanding additional collateral pledges or liquidation of some of the existing collateral to reduce borrowing levels. We manage this risk by maintaining an adequate balance of available cash and unpledged securities. An event of default or termination event under the standard MRA would give our counterparty the option to terminate all repurchase transactions existing with us and require any amount due to be payable immediately. In addition, certain of our MRAs contain a restriction that prohibits our leverage from exceeding twelve times our stockholders’ equity as well as termination events in the case of significant reductions in equity capital. We also may receive cash or securities as collateral from our derivative counterparties which we may use as additional collateral for repurchase agreements. Certain interest rate swap contracts provide for cross collateralization and cross default with repurchase agreements and other contracts with the same counterparty. At June 30, 2023 and December 31, 2022, BUCKLER accounted for 48.4% and 50.2%, respectively, of our aggregate borrowings and had an amount at risk of 7.8% and 12.9%, respectively, of our total stockholders' equity with a weighted average maturity of 21 days and 15 days, respectively, on repurchase agreements, net (see Note 14 - Related Party Transactions).

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Note 7 - Derivatives We enter into derivative transactions to manage our interest rate risk and agency mortgage rate exposures. We have agreements with our derivative counterparties that provide for the posting of collateral based on the fair values of our derivatives. Through this margin process, either we or our counterparties may be required to pledge cash or securities as collateral. Collateral requirements vary by counterparty and change over time based on the fair value, notional amount and remaining term of the contracts. Certain contracts provide for cross collateralization and cross default with repurchase agreements and other contracts with the same counterparty. Interest rate swap contracts are designed to lock in funding costs for repurchase agreements associated with our assets in such a way to help assure the realization of net interest margins. Such transactions are based on assumptions about prepayments which, if not realized, will cause transaction results to differ from expectations. Interest rate swaptions generally provide us the option to enter into an interest rate swap agreement at a certain point of time in the future with a predetermined notional amount, stated term and stated rate of interest in the fixed leg and interest rate index on the floating leg. Basis swap contracts allow us to exchange one floating interest rate basis for another, thereby allowing us to diversify our floating rate basis exposures. All of our interest rate contracts have floating leg interest rate indexes of either the Fed Funds Rate or SOFR. The Fed Funds Rate is published daily by the New York Federal Reserve and is a measure of unsecured borrowings by depository institutions from other depository institutions or GSEs. SOFR is published daily by the New York Federal Reserve and is the average overnight rate for borrowings secured by U.S. Treasury securities. We enter into interest rate swap contracts either directly with a counterparty (a “bilateral” contract) or through a centrally-cleared swap contract. In a bilateral contract, we exchange margin collateral with the counterparty and have exposure to counterparty risk. In a centrally-cleared contract, we exchange margin collateral with a Futures Clearing Merchant, with whom we have opened an account. Our counterparty risk is limited to the clearing exchange itself. All of our centrally-cleared swaps are cleared by the CME. In general, centrally-cleared interest rate swap contracts require us to post higher initial margin than bilateral contracts. Futures contracts are traded on the CME which requires the use of daily mark-to-market collateral and the CME provides substantial credit support. The collateral requirements of the CME require us to pledge assets under a bi-lateral margin arrangement, including either cash or Agency Securities and these requirements may vary and change over time based on the market value, notional amount and remaining term of the futures contracts. In the event we are unable to meet a margin call under one of our futures contracts, the counterparty to such agreement may have the option to terminate or close-out all of the outstanding futures contracts with us. In addition, any close-out amount due to the counterparty upon termination of the counterparty’s transactions would be immediately payable by us pursuant to the applicable agreement. TBA Agency Securities are forward contracts for the purchase (“long position”) or sale (“short position”) of Agency Securities at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific Agency Securities delivered into the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association, are not known at the time of the transaction. We may enter into TBA Agency Securities as a means of hedging against short-term changes in interest rates. We may also enter into TBA Agency Securities as a means of acquiring or disposing of Agency Securities and we may from time to time utilize TBA dollar roll transactions to finance Agency Security purchases. We estimate the fair value of TBA Agency Securities based on similar methods used to value our Agency Securities. We have netting arrangements in place with all derivative counterparties pursuant to standard documentation developed by ISDA. We are also required to post or hold cash collateral based upon the net underlying market value of our open positions with the counterparty. A decline in the value of the open positions with the counterparty could result in the counterparties demanding additional collateral pledges or liquidation of some of the existing collateral to reduce borrowing levels. We manage this risk by maintaining an adequate balance of available cash and unpledged securities. An event of default or termination event under the standard ISDA would give our counterparty the option to terminate all repurchase transactions existing with us and require any amount due to be payable immediately. In addition, certain of our ISDAs contain a restriction that prohibits our leverage from exceeding twelve times our stockholders’ equity as well as termination events in the case of significant reductions in equity capital. The following tables present information about the potential effects of netting our derivatives if we were to offset the assets and liabilities on the accompanying consolidated balance sheets.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 8 - Commitments and Contingencies Management The Company is managed by ACM, pursuant to a management agreement (see also Note 14 - Related Party Transactions). The management agreement entitles ACM to receive management fees payable monthly in arrears. Currently, the monthly management fee is 1/12th of the sum of (a) 1.5% of gross equity raised up to $1.0 billion plus (b) 0.75% of gross equity raised in excess of $1.0 billion. Gross equity raised includes the total amounts of paid in capital relating to both our common and preferred stock, plus brokerage commissions and other costs of capital raising. Amounts paid to shareholders to repurchase stock, before any brokerage commissions and costs, reduces gross equity raised. Dividends specifically designated by the Board as liquidation dividends will reduce the amount of gross equity raised. To date, the Board has not so designated any of the dividends paid by the Company. Realized and unrealized gains and losses do not affect the amount of gross equity raised. At June 30, 2023, the average management fee rate, prior to management fees waived, was 0.94% based on gross equity raised of $4,042,078 and effectively a rate of 2.95% based on total stockholders' equity. ACM began waiving 40% of its management fee during the second quarter of 2020 and on January 13, 2021, ACM notified ARMOUR that it intended to adjust the fee waiver to the rate of $2,400 for the first quarter of 2021 and $800 per month thereafter. On April 20, 2021, ACM notified ARMOUR that it intended to adjust the fee waiver to the rate of $2,100 for the second quarter of 2021 and $700 per month thereafter. On October 25, 2021, ACM notified ARMOUR that it intended to adjust the fee waiver from the rate of $700 per month to $650 per month, effective November 1, 2021, until further notice. On February 14, 2023, ACM notified ARMOUR that it intended to adjust the fee waiver to the rate of $1,650 for the first quarter of 2023 and $550 per month thereafter until ACM provides further notice to ARMOUR. ACM may terminate this waiver for any month by providing notice to ARMOUR on or before the 25th day of the preceding month. This waiver does not constitute a waiver of any other amounts due to ACM from ARMOUR under the Agreement or otherwise, including but not limited to any expense reimbursements, any amounts calculated by reference to the contractual Base Management Fee, or any awards under the 2009 Stock Incentive Plan as amended (the “Plan”). During the three and six months ended June 30, 2023, and June 30, 2022 ACM waived management fees of $1,650 and $3,300 and $1,950 and $3,900, respectively. The monthly management fees are not calculated based on the performance of our assets. Accordingly, the payment of our monthly management fees may not decline in the event of a decline in our earnings and may cause us to incur losses. We are also responsible for any costs and expenses that ACM incurs solely on our behalf other than the various overhead expenses specified in the terms of the management agreement. On February 14, 2023, the Company extended the contractual term of the management agreement through December 31, 2029. Based on the management fee base, gross equity raised, as of June 30, 2023, the Company’s contractual management fee commitments are: Year Contractual Management Fee Remainder of 2023 $ 31,500 2024 37,800 2025 37,800 2026 37,800 2027 37,800 2028 37,800 2029 37,800 Total $ 258,300 The Company cannot voluntarily terminate the management agreement without cause before the expiration of its contractual term. If the management agreement is terminated in connection with a liquidation of the Company or certain business combination transactions, the Company is obliged to pay ACM a termination fee equal to 4 times the contractual management fee (before any waiver) for the preceding 12 months. Indemnifications and Litigation We enter into certain contracts that contain a variety of indemnifications, principally with ACM and underwriters, against third-party claims for errors and omissions in connection with their services to us. We have not incurred any costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the estimated fair value of these agreements, as well as the maximum amount attributable to past events, is not material. Accordingly, we have no liabilities recorded for these agreements at June 30, 2023 and December 31, 2022. Nine putative class action lawsuits have been filed in connection with the tender offer (the “Tender Offer”) and merger (the “Merger”) for JAVELIN. The Tender Offer and Merger are collectively defined herein as the “Transactions.” All nine suits name ARMOUR, the previous members of JAVELIN’s board of directors prior to the Merger (of which eight are current members of ARMOUR’s board of directors) (the “Individual Defendants”) and JMI Acquisition Corporation (“Acquisition” ) as defendants. Certain cases also name ACM and JAVELIN as additional defendants. The lawsuits were brought by purported holders of JAVELIN’s common stock, both individually and on behalf of a putative class of JAVELIN’s stockholders, alleging that the Individual Defendants breached their fiduciary duties owed to the plaintiffs and the putative class of JAVELIN stockholders, including claims that the Individual Defendants failed to properly value JAVELIN; failed to take steps to maximize the value of JAVELIN to its stockholders; ignored or failed to protect against conflicts of interest; failed to disclose material information about the Transactions; took steps to avoid competitive bidding and to give ARMOUR an unfair advantage by failing to adequately solicit other potential acquirors or alternative transactions; and erected unreasonable barriers to other third-party bidders. The suits also allege that ARMOUR, JAVELIN, ACM and Acquisition aided and abetted the alleged breaches of fiduciary duties by the Individual Defendants. The lawsuits seek equitable relief, including, among other relief, to enjoin consummation of the Transactions, or rescind or unwind the Transactions if already consummated, and award costs and disbursements, including reasonable attorneys’ fees and expenses. The sole Florida lawsuit was never served on the defendants, and that case was voluntarily dismissed and closed on January 20, 2017 . On April 25, 2016, the Maryland court issued an order consolidating the eight Maryland cases into one action, captioned In re JAVELIN Mortgage Investment Corp. Shareholder Litigation (Case No. 24-C-16-001542), and designated counsel for one of the Maryland cases as interim lead co-counsel. On May 26, 2016, interim lead counsel filed the Consolidated Amended Class Action Complaint for Breach of Fiduciary Duty asserting consolidated claims of breach of fiduciary duty, aiding and abetting the breaches of fiduciary duty, and waste. On June 27, 2016, defendants filed a Motion to Dismiss the Consolidated Amended Class Action Complaint for failing to state a claim upon which relief can be granted. A hearing was held on the Motion to Dismiss on March 3, 2017, and the Court reserved ruling. The Court has deferred ruling on the Motion to Dismiss several times. On October 25, 2022, the court deferred the Order of Dismissal until May 1, 2023, and if the case was not fully disposed of by that date, the clerk would enter on the docket "dismissed for lack of prosecution without prejudice." To date, no further action has been taken by the court.

Unrealized gains and losses on open interest rate contracts are not included in the determination of REIT taxable income. Realized gains and losses on interest rate contracts and futures contracts terminated before their maturity are deferred and amortized over the remainder of the original term of the contract for REIT taxable income. At June 30, 2023 and December 31, 2022, we had approximately $268,923 and $307,316, respectively, of net deductible expense relating to previously terminated interest rate swap and treasury futures contracts amortizing through the year 2032. At June 30, 2023, we had $257,341 of net operating loss carryforwards available for use indefinitely.

As such, the TRS is taxable as a domestic C corporation and subject to federal, state, and local income taxes based upon its taxable income. The aggregate tax basis of our assets and liabilities was greater than our total Stockholders’ Equity at June 30, 2023 by approximately $132,413, or approximately $0.64 per common share (based on the 206,810 common shares then outstanding). State and federal tax returns for the years 2019 and later remain open and are subject to possible examination. We are required and intend to timely distribute substantially all of our REIT taxable income in order to maintain our REIT status under the Code. Total dividend payments to stockholders for the three and six months ended June 30, 2023 and June 30, 2022 were $51,333 and $106,332 and $35,153 and $67,256, respectively. Our estimated REIT taxable income and dividend requirements to maintain our REIT status are determined on an annual basis. Dividends paid in excess of current tax earnings and profits for the year will generally not be taxable to common stockholders. Our management is responsible for determining whether tax positions taken by us are more likely than not to be sustained on their merits. We have no material unrecognized tax benefits or material uncertain tax positions.

Related Party Transactions [Abstract]
Related Party Transactions	Note 14 - Related Party Transactions ACM The Company is managed by ACM, pursuant to a management agreement. All of our executive officers are also employees of ACM. ACM manages our day-to-day operations, subject to the direction and oversight of the Board. The management agreement runs through December 31, 2029 and is thereafter automatically renewed for an additional five-year term unless terminated under certain circumstances. Either party must provide 180 days prior written notice of any such termination. Under the terms of the management agreement, ACM is responsible for costs incident to the performance of its duties, such as compensation of its employees and various overhead expenses. ACM is responsible for the following primary roles: • Advising us with respect to, arranging for and managing the acquisition, financing, management and disposition of, elements of our investment portfolio; • Evaluating the duration risk and prepayment risk within the investment portfolio and arranging borrowing and hedging strategies; • Coordinating capital raising activities; • Advising us on the formulation and implementation of operating strategies and policies, arranging for the acquisition of assets, monitoring the performance of those assets and providing administrative and managerial services in connection with our day-to-day operations; and • Providing executive and administrative personnel, office space and other appropriate services required in rendering management services to us. ACM began waiving 40% of its management fee during the second quarter of 2020 and on January 13, 2021, ACM notified ARMOUR that it intended to adjust the fee waiver to the rate of $2,400 for the first quarter of 2021 and $800 per month thereafter. On April 20, 2021, ACM notified ARMOUR that it intended to adjust the fee waiver to the rate of $2,100 for the second quarter of 2021 and $700 per month thereafter. On October 25, 2021, ACM notified ARMOUR that it intended to adjust the fee waiver from the rate of $700 per month to $650 per month, effective November 1, 2021, until further notice. On February 14, 2023, ACM notified ARMOUR that it intended to adjust the fee waiver to the rate of $1,650 for the first quarter of 2023 and $550 per month thereafter until ACM provides further notice to ARMOUR (see Note 8 - Commitments and Contingencies). The following table reconciles the fees incurred in accordance with the management agreement for the three and six months ended June 30, 2023 and June 30, 2022. For the Three Months Ended June 30, For the Six Months Ended June 30, 2023 2022 2023 2022 ARMOUR management fees $ 9,377 $ 8,282 $ 18,605 $ 16,407 Less management fees waived (1,650) (1,950) (3,300) (3,900) Total management fee expense $ 7,727 $ 6,332 $ 15,305 $ 12,507 We are required to take actions as may be reasonably required to permit and enable ACM to carry out its duties and obligations. We are also responsible for any costs and expenses that ACM incurred solely on our behalf other than the various overhead expenses specified in the terms of the management agreement. For the three and six months ended June 30, 2023 and June 30, 2022, we reimbursed ACM $170 and $405 and $130 and $237, respectively, for other expenses incurred on our behalf. In 2017, 2020, 2021 and 2022, we elected to grant restricted stock unit awards to our executive officers and other ACM employees that generally vest over 5 years. In 2017, 2020, 2021 and 2022, we elected to grant RSUs to the Board. We recognized stock based compensation expense of $118 and $259 and $140 and $302 for the three and six months ended June 30, 2023 and June 30, 2022, respectively. BUCKLER At June 30, 2023, we held an ownership interest in BUCKLER of 10.8%, which is included in prepaid and other assets in our consolidated balance sheet and is accounted for using the equity method as BUCKLER maintains specific ownership accounts. The value of the investment was $466 at June 30, 2023 and $377 at December 31, 2022, reflecting our total investment plus our share of BUCKLER’s operating results, in accordance with the terms of the operating agreement of BUCKLER that our independent directors negotiated. The primary purpose of our investment in BUCKLER is to facilitate our access to repurchase financing on potentially attractive terms (considering rate, term, size, haircut, relationship and funding commitment) compared to other suitable repurchase financing counterparties. Our operating agreement with BUCKLER contains certain provisions to benefit and protect the Company, including (1) sharing in any (a) defined profits realized by BUCKLER from the anticipated financing spreads resulting from repurchase financing facilitated by BUCKLER, and (b) distributions from BUCKLER to its members of net cash receipts, and (2) the realization of anticipated savings from reduced clearing, brokerage, trading and administrative fees. In addition, the independent directors of the Company must approve, in their sole discretion, any third-party business engaged by BUCKLER and may cause BUCKLER to wind up and dissolve and promptly return certain subordinated loans we provide to BUCKLER as regulatory capital (as described more fully below) if the independent directors reasonably determine that BUCKLER’s ability to provide attractive securities transactions for the Company is materially adversely affected. For each of the three and six months ended June 30, 2023 and June 30, 2022, we earned $0 from BUCKLER as an allocated share of Financing Gross Profit for a reduction of interest on repurchase agreements charged to the Company. Financing Gross Profit is defined in the operating agreement, subject to a contractually required reduction in our share of the Financing Gross Profit of $306 per annum, which expired at the end of the first quarter of 2022. Effective March 20, 2023, the Company committed to provide on demand a subordinated loan agreement to BUCKLER in an amount up to $200,000. The commitment extends through March 20, 2026, and is collateralized by mortgage backed and/or U.S. Treasury Securities owned by the Company and pledged to BUCKLER. The commitment is treated by BUCKLER currently as capital for regulatory purposes and BUCKLER may pledge the securities to secure its own borrowings. This arrangement replaced the prior $105.0 million subordinated loan, which was to mature on May 1, 2025. In March 2023, BUCKLER, at its option after obtaining regulatory approval, repaid all of the principal amount of the loan. The loan had a stated interest rate of zero, plus additional interest payable to the Company in an amount equal to the amount of interest earned by BUCKLER on the investment of the loan proceeds, generally in government securities funds. For the three and six months ended June 30, 2023 and June 30, 2022, the Company earned $0 and $973 and $157 and $176, respectively, of interest on this loan. On February 22, 2021, the Company entered into an uncommitted revolving credit facility and security agreement with BUCKLER. Under the terms of the facility, the Company may, in its sole and absolute discretion, provide drawings to BUCKLER of up to $50,000. Interest on drawings is payable monthly at the Federal Reserve Bank of New York SOFR plus 2% per annum. To date, BUCKLER has not yet used the facility and therefore no interest expense was payable for the six months ended June 30, 2023. With BUCKLER as the sales agent, under the 2021 Common stock ATM Sales Agreement, we sold 10,910 and 37,013 common shares for proceeds of $55,892 and $215,193, net of issuance costs and commissions of approximately $486 and $2,215 during the three and six months ended June 30, 2023, respectively. We also repurchased 425 and 1,268 common shares under the current repurchase authorization which cost $2,072 and $6,377, including commissions of approximately $18 and $54, respectively, to BUCKLER during the three and six months ended June 30, 2023. In July 2023, we sold 6,117 shares under the 2021 Common stock ATM Sales Agreement for proceeds of $31,354, net of issuance costs and commissions of approximately $269 to BUCKLER (see Note 10 - Stockholders' Equity). The table below summarizes other transactions with BUCKLER for the six months ended June 30, 2023 and for the year ended December 31, 2022.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X promulgated by the SEC. Accordingly, the condensed financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2023. These unaudited consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2022.
Consolidation	The unaudited consolidated financial statements include the accounts of ARMOUR Residential REIT, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated.
Use of Estimates	The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates affecting the accompanying condensed consolidated financial statements include the valuation of MBS, including an assessment of the allowance for credit losses, and derivative instruments. Interest earned/paid on cash collateral posted/held on interest rate swap contracts was reclassified from Interest Income to Gain (loss) on derivatives, net, in the consolidated financial statements to conform to current presentation. No other reclassifications have been made to previously reported amounts.
Cash	Cash Cash includes cash on deposit with financial institutions. We may maintain deposits in federally insured financial institutions in excess of federally insured limits. However, management believes we are not exposed to significant credit risk due to the financial position and creditworthiness of the depository institutions in which those deposits are held.
Cash Collateral Posted To/By Counterparties	Cash Collateral Posted To/By Counterparties Cash collateral posted to/by counterparties represents cash posted by us to counterparties or posted by counterparties to us as collateral. Cash collateral posted to/by counterparties may include collateral for interest rate swap contracts, interest rate swaptions, basis swap contracts, futures contracts, repurchase agreements on our MBS and our Agency Securities purchased or sold on a to-be-announced basis ("TBA Agency Securities").
Investments in Securities, at Fair Value	Investments in Securities, at Fair Value Our investments in securities are generally classified as either available for sale or trading securities. Management determines the appropriate classifications of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date. Trading Securities are reported at their estimated fair values with gains and losses included in Other Income (Loss) as a component of the consolidated statements of operations and comprehensive income (loss). Available for Sale Securities represented investments that we intended to hold for extended periods of time and were reported at their estimated fair values with unrealized gains and losses excluded from earnings and reported as part of comprehensive income (loss). During the first quarter of 2023, we sold the remaining balance of our Available for Sale Securities which resulted in a realized loss of $(7,471).
Receivables and Payables for Unsettled Sales and Purchases	Receivables and Payables for Unsettled Sales and PurchasesWe account for purchases and sales of securities on the trade date, including purchases and sales for forward settlement. Receivables and payables for unsettled trades represent the agreed trade price multiplied by the outstanding balance of the securities at the balance sheet date.
Accrued Interest Receivable and Payable	Accrued Interest Receivable and Payable Accrued interest receivable includes interest accrued between payment dates on securities and interest on unsettled sales of securities. Accrued interest payable includes interest on unsettled purchases of securities and interest on repurchase agreements. At certain times, we may have interest payable on U.S. Treasury Securities sold short.
Repurchase Agreements, net	Repurchase Agreements, net We finance the acquisition of the majority of our MBS through the use of repurchase agreements. Our repurchase agreements are secured by our MBS and bear interest rates that have moved in close relationship to the Federal Funds Effective Rate ("Fed Funds Rate") and the Secured Overnight Funding Rate ("SOFR"). Under these repurchase agreements, we sell MBS to a lender and agree to repurchase the same MBS in the future for a price that is higher than the original sales price. The difference between the sales price that we receive and the repurchase price that we pay represents interest paid to the lender, which accrues over the life of the repurchase agreement. A repurchase agreement operates as a financing arrangement under which we pledge our MBS as collateral to secure a loan which is equal in value to a specified percentage of the estimated fair value of the pledged collateral. We retain beneficial ownership of the pledged collateral. At the
Obligations to Return Securities Received as Collateral, at Fair Value	Obligations to Return Securities Received as Collateral, at Fair ValueWe also sell to third parties the U.S. Treasury Securities received as collateral for reverse repurchase agreements and recognize the resulting obligation to return said U.S. Treasury Securities as a liability on our consolidated balance sheet. Interest is recorded on the repurchase agreements, reverse repurchase agreements and U.S. Treasury Securities on an accrual basis and presented as net interest expense. Both parties to the transaction have the right to make daily margin calls based on changes in the fair value of the collateral received and/or pledged.
Derivatives, at Fair Value	Derivatives, at Fair Value We recognize all derivatives individually as either assets or liabilities at fair value on our consolidated balance sheets. All changes in the fair values of our derivatives are reflected in our consolidated statements of operations and comprehensive income (loss). We designate derivatives as hedges for tax purposes and any unrealized derivative gains or losses would not affect our distributable net taxable income. These transactions may include interest rate swap contracts, interest rate swaptions, basis swap contracts and futures contracts. We also may utilize forward contracts for the purchase or sale of TBA Agency Securities. We account for TBA Agency Securities as derivative instruments if it is reasonably possible that we will not take or make physical delivery of the Agency Security upon settlement of the contract. We account for TBA dollar roll transactions as a series of derivative transactions. We may also purchase and sell TBA Agency Securities as a means of investing in and financing Agency Securities (thereby increasing our “at risk” leverage) or as a means of disposing of or reducing our exposure to Agency Securities (thereby reducing our “at risk” leverage). We agree to purchase or sell, for future delivery, Agency Securities with certain principal and interest terms and certain types of collateral, but the particular Agency Securities to be delivered are not identified until shortly before the TBA settlement date. We may also choose, prior to settlement, to move the settlement of these securities out to a later date by entering into an offsetting short or long position (referred to as a “pair off”), net settling the paired off positions for cash, and simultaneously purchasing or selling a similar TBA Agency Security for a later settlement date. This transaction is commonly referred to as a “dollar roll.” When it is reasonably possible that we will pair off a TBA Agency Security, we account for that contract as a derivative.
Impairment of Assets	Impairment of Assets Impairment of available for sale securities was assessed at least on a quarterly basis and more frequently when economic or market concerns warranted such evaluation. An impairment was considered if we (1) intended to sell the available for sale securities, or (2) believed it was more likely than not that we were required to sell the securities before recovery (for example, because of liquidity requirements or contractual obligations) and a credit impairment existed where
Revenue Recognition	Revenue Recognition Interest income is earned and recognized on Agency Securities based on their unpaid principal amounts and their contractual terms. Recognition of interest income commences on the settlement date of the purchase transaction and continues through the settlement date of the sale transaction. Premiums and discounts associated with the purchase of Multi-Family MBS, which are generally not subject to prepayment, are amortized or accreted into interest income over the contractual lives of the securities using a level yield method. Premiums and discounts associated with the purchase of other Agency Securities are amortized or accreted into interest income over the actual lives of the securities, reflecting actual prepayments as they occur. Purchase and sale transactions (including TBA Agency Securities) are recorded on the trade date to the extent it is probable that we will take or make timely physical delivery of the related securities. Gains or losses realized from sales of available for sale securities are reclassified into income from Comprehensive Income (Loss) and are determined using the specific identification method. Interest income on U.S. Treasury Securities is recognized based on their unpaid principal amounts and their contractual terms. Recognition of interest income commences on the settlement date of the purchase transaction and continues through the settlement date of the sale transaction.
Comprehensive Income (Loss)	Comprehensive Income (Loss)Comprehensive income (loss) refers to the sum of net income and other comprehensive income (loss). It represents all changes in equity during a period from transactions and other events from non-owner sources. It excludes all changes in equity during a period resulting from investments by owners and distributions to owners.
