Accounting Policies [Abstract]
DESCRIPTION OF BUSINESS	1. DESCRIPTION OF BUSINESS Annaly Capital Management, Inc. (the “Company” or “Annaly”) is a Maryland corporation that commenced operations on February 18, 1997. The Company is a leading diversified capital manager with investment strategies across mortgage finance. The Company owns a portfolio of real estate related investments, including mortgage pass-through certificates, collateralized mortgage obligations, credit risk transfer (“CRT”) securities, other securities representing interests in or obligations backed by pools of mortgage loans, residential mortgage loans and mortgage servicing rights (“MSR”). The Company’s principal business objective is to generate net income for distribution to its stockholders and optimize its returns through prudent management of its diversified investment strategies. The Company is an internally-managed company that has elected to be taxed as a Real Estate Investment Trust (“REIT”) as defined under the Internal Revenue Code of 1986, as amended, and regulations promulgated thereunder (the “Code”). The Company’s three investment groups are primarily comprised of the following: Investment Groups Description Annaly Agency Group Invests in Agency mortgage-backed securities (“MBS”) collateralized by residential mortgages which are guaranteed by Fannie Mae, Freddie Mac or Ginnie Mae and complementary investments within the Agency market, including Agency commercial mortgage-backed securities. Annaly Residential Credit Group Invests primarily in non-Agency residential whole loans and securitized products within the residential and commercial markets. Annaly Mortgage Servicing Rights Group Invests in MSR, which provide the right to service residential mortgage loans in exchange for a portion of the interest payments made on the loans. In April 2022, the Company entered into a definitive agreement to sell substantially all of the assets that comprise the Annaly Middle Market Lending (“MML”) portfolio, including assets held on balance sheet as well as assets managed for third parties (collectively, the “MML Portfolio”).

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	2. BASIS OF PRESENTATION The accompanying consolidated financial statements and related notes of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The accompanying consolidated financial statements and related notes are unaudited and should be read in conjunction with the audited consolidated financial statements included in the Company’s most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the “2022 Form 10-K”). The consolidated financial information as of December 31, 2022 has been derived from audited consolidated financial statements included in the Company’s 2022 Form 10-K. The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported balance sheet amounts and/or disclosures at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Reverse Stock Split On September 8, 2022, the Company announced that its Board had unanimously approved a reverse stock split of the Company’s common stock at a ratio of 1-for-4 (the “Reverse Stock Split”). The Reverse Stock Split was effective following the close of business on September 23, 2022 (the “Effective Time”). Accordingly, at the Effective Time, every four issued and outstanding shares of the Company’s common stock were converted into one share of the Company’s common stock. No fractional shares were issued in connection with the Reverse Stock Split. Instead, each stockholder that would have held fractional shares as a result of the Reverse Stock Split received cash in lieu of such fractional shares. The par value per share of the Company’s common stock remained unchanged at $0.01 per share after the Reverse Stock Split. Accordingly, for all historical periods presented, an amount equal to the par value of the reduced number of shares resulting from the Reverse Stock Split was reclassified from Common stock to Additional paid in capital in the Company’s Consolidated Statements of Financial Condition. All references made to share or per share amounts in the accompanying consolidated financial statements and disclosures have been retroactively adjusted, where applicable, to reflect the effects of the Reverse Stock Split.

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	3. SIGNIFICANT ACCOUNTING POLICIES The Company’s significant accounting policies are described below or are included elsewhere in these notes to the consolidated financial statements. Principles of Consolidation – The consolidated financial statements include the accounts of the entities where the Company has a controlling financial interest. In order to determine whether the Company has a controlling financial interest, it first evaluates whether an entity is a voting interest entity (“VOE”) or a variable interest entity (“VIE”). All intercompany balances and transactions have been eliminated in consolidation. Voting Interest Entities – A VOE is an entity that has sufficient equity and in which equity investors have a controlling financial interest. The Company consolidates VOEs where it has a majority of the voting equity of such VOE. Variable Interest Entities – A VIE is defined as an entity in which equity investors (i) do not have the characteristics of a controlling financial interest, and/or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. A VIE is required to be consolidated by its primary beneficiary, which is defined as the party that has both (i) the power to control the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE causes the Company’s consolidation conclusion to change. Refer to the “Variable Interest Entities” Note for further information. Equity Method Investments - For entities that are not consolidated, but where the Company has significant influence over the operating or financial decisions of the entity, the Company accounts for the investment under the equity method of accounting. In accordance with the equity method of accounting, the Company will recognize its share of earnings or losses of the investee in the period in which they are reported by the investee. The Company also considers whether there are any indicators of other-than-temporary impairment of joint ventures accounted for under the equity method. These investments are included in Other assets with income or loss included in Other, net. Cash and Cash Equivalents – Cash and cash equivalents include cash on hand, cash held in money market funds on an overnight basis and cash pledged as collateral with counterparties. Cash deposited with clearing organizations is carried at cost, which approximates fair value. Cash and securities deposited with clearing organizations and collateral held in the form of cash on margin with counterparties to the Company’s interest rate swaps and other derivatives totaled $1.6 billion and $1.4 billion at March 31, 2023 and December 31, 2022, respectively. Fair Value Measurements and the Fair Value Option – The Company reports various investments at fair value, including certain eligible financial instruments elected to be accounted for under the fair value option (“FVO”). The Company chooses to elect the FVO in order to simplify the accounting treatment for certain financial instruments. Items for which the FVO has been elected are presented at fair value in the Consolidated Statements of Financial Condition and any change in fair value is recorded in Net gains (losses) on investments and other in the Consolidated Statements of Comprehensive Income (Loss). For additional information regarding financial instruments for which the Company has elected the FVO refer to the table in the “Financial Instruments” Note. Refer to the “Fair Value Measurements” Note for a complete discussion on the methodology utilized by the Company to estimate the fair value of certain financial instruments. Offsetting Assets and Liabilities - The Company elected to present all derivative instruments on a gross basis as discussed in the “Derivative Instruments” Note. Reverse repurchase and repurchase agreements are presented net in the Consolidated Statements of Financial Condition if they meet the offsetting criteria. Refer to the “Secured Financing” Note for further discussion on reverse repurchase and repurchase agreements. Derivative Instruments – Derivatives are recognized as either assets or liabilities at fair value in the Consolidated Statements of Financial Condition with changes in fair value recognized in the Consolidated Statements of Comprehensive Income (Loss). The changes in the estimated fair value are presented within Net gains (losses) on derivatives. None of the Company’s derivative transactions have been designated as hedging instruments for accounting purposes. Refer to the “Derivative Instruments” Note for further discussion. Stock-Based Compensation – The Company measures compensation expense for stock-based awards at fair value, which is generally based on the grant-date fair value of the Company’s common stock. Compensation expense is recognized ratably over the vesting or requisite service period of the award. Stock-based awards that contain market-based conditions are valued using a model. Compensation expense for awards with performance conditions is recognized based on the probable outcome of the performance condition at each reporting date. Compensation expense for awards with market conditions is recognized irrespective of the probability of the market condition being achieved and is not reversed if the market condition is not met. Stock-based awards that do not require future service (i.e., vested awards) are expensed immediately. Forfeitures are recorded when they occur. The Company generally issues new shares of common stock upon delivery of stock-based awards. Interest Income - The Company recognizes interest income primarily on Residential Securities (as defined in the “Securities” Note), residential mortgage loans, commercial investments and reverse repurchase agreements. Interest accrued but not received is recognized as Interest receivable on the Consolidated Statements of Financial Condition. Interest income is presented as a separate line item on the Consolidated Statements of Comprehensive Income (Loss). For its securities, the Company recognizes coupon income, which is a component of interest income, based upon the outstanding principal amounts of the financial instruments and their contractual terms. In addition, the Company amortizes or accretes premiums or discounts into interest income for its Agency mortgage-backed securities (other than interest-only securities, multifamily and reverse mortgages), taking into account estimates of future principal prepayments in the calculation of the effective yield. The Company recalculates the effective yield as differences between anticipated and actual prepayments occur. Using third party model and market information to project future cash flows and expected remaining lives of securities, the effective interest rate determined for each security is applied as if it had been in place from the date of the security’s acquisition. The amortized cost of the security is then adjusted to the amount that would have existed had the new effective yield been applied since the acquisition date, which results in a cumulative premium amortization adjustment in each period. The adjustment to amortized cost is offset with a charge or credit to interest income. Changes in interest rates and other market factors will impact prepayment speed projections and the amount of premium amortization recognized in any given period. Premiums or discounts associated with the purchase of Agency interest-only securities, reverse mortgages and residential credit securities are amortized or accreted into interest income based upon current expected future cash flows with any adjustment to yield made on a prospective basis. Premiums or discounts associated with the purchase of multifamily securities are amortized or accreted into interest income based upon their contractual payment terms. If a prepayment occurs, an adjustment is made to the unpaid principal balance and unamortized premium or discount in the current period and the original effective yield continues to be applied. Premiums and discounts associated with the purchase of residential mortgage loans and with those transferred or pledged to securitization trusts are primarily amortized or accreted into interest income over their estimated remaining lives using the effective interest rates inherent in the estimated cash flows from the mortgage loans. Amortization of premiums and accretion of discounts are presented in Interest income in the Consolidated Statements of Comprehensive Income (Loss). If collection of a loan’s principal or interest is in doubt or the loan is 90 days or more past due, interest income is not accrued. For nonaccrual status loans carried at fair value or held for sale, interest is not accrued but is recognized on a cash basis. For nonaccrual status loans carried at amortized cost, if collection of principal is not in doubt but collection of interest is in doubt, interest income is recognized on a cash basis. If collection of principal is in doubt, any interest received is applied against principal until collectability of the remaining balance is no longer in doubt; at that point, any interest income is recognized on a cash basis. Generally, a loan is returned to accrual status when the borrower has resumed paying the full amount of the scheduled contractual obligation, if all principal and interest amounts contractually due are reasonably assured of repayment within a reasonable period of time and there is a sustained period of repayment performance by the borrower. The Company has made an accounting policy election not to measure an allowance for loans losses for accrued interest receivable. If interest receivable is deemed to be uncollectible or not collected within 90 days of its contractual due date for commercial loans or 120 days for corporate debt carried at amortized cost, it is written off through a reversal of interest income. Any interest written off that is recovered is recognized as interest income. Refer to the “Interest Income and Interest Expense” Note for further discussion of interest income. Income Taxes – The Company has elected to be taxed as a REIT and intends to comply with the provisions of the Code, with respect thereto. As a REIT, the Company will not incur federal income tax to the extent that it distributes its taxable income to its stockholders. The Company and certain of its direct and indirect subsidiaries have made separate joint elections to treat these subsidiaries as taxable REIT subsidiaries (“TRSs”). As such, each of these TRSs is taxable as a domestic C corporation and subject to federal, state and local income taxes based upon its taxable income. Refer to the “Income Taxes” Note for further discussion on income taxes. Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”). There were no recent ASUs that are expected to have a significant impact on the Company’s consolidated financial statements when adopted or that had a significant impact on the Company’s consolidated financial statements upon adoption.

Investments, Debt and Equity Securities [Abstract]
SECURITIES	5. SECURITIES The Company’s investments in securities include agency, credit risk transfer, non-agency and commercial mortgage-backed securities. All of the debt securities are classified as available-for-sale. Available-for-sale debt securities are carried at fair value, with changes in fair value recognized in other comprehensive income, unless the fair value option is elected in which case changes in fair value are recognized in Net gains (losses) on investments and other in the Consolidated Statements of Comprehensive Income (Loss). Effective July 1, 2022, the Company elected the fair value option for any newly purchased Agency mortgage-backed securities in order to simplify the accounting for these securities. Agency mortgage-backed securities purchased prior to July 1, 2022, are still classified as available-for-sale with changes in fair value recognized in other comprehensive income. During the three months ended March 31, 2023, $386.7 million of unrealized gains (losses) on Agency mortgage-backed securities were reported in Net gains (losses) on investments and other in the Company's Consolidated Statements of Comprehensive Income (Loss). The Company has also elected the fair value option for CRT securities, interest only securities, Non-Agency and commercial mortgage-backed securities in order to simplify the accounting. Transactions for regular-way securities are recorded on trade date, including to-be-announced (“TBA”) securities that meet the regular-way securities scope exception from derivative accounting. Gains and losses on disposals of securities are recorded on trade date based on the specific identification method. Impairment – Management evaluates available-for-sale securities where the fair value option has not been elected and held-to-maturity debt securities for impairment at least quarterly, and more frequently when economic or market conditions warrant such evaluation. When the fair value of an available-for-sale security is less than its amortized cost, the security is considered impaired. For securities that are impaired, the Company determines if it (1) has the intent to sell the security, (2) is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, or (3) does not expect to recover the entire amortized cost basis of the security. Further, the security is analyzed for credit loss (the difference between the present value of cash flows expected to be collected and the amortized cost basis). The credit loss, if any, will then be recognized in the Consolidated Statements of Comprehensive Income (Loss) as a securities loss provision and reflected as an allowance for credit losses on securities on the Consolidated Statements of Financial Condition, while the balance of losses related to other factors will be recognized as a component of Other comprehensive income (loss). When the fair value of a held-to-maturity security is less than the cost, the Company performs an analysis to determine whether it expects to recover the entire cost basis of the security. Agency Mortgage-Backed Securities - The Company invests in mortgage pass-through certificates, collateralized mortgage obligations and other MBS representing interests in or obligations backed by pools of residential or multifamily mortgage loans and certificates. Many of the underlying loans and certificates are guaranteed by the Government National Mortgage Association (“Ginnie Mae”), the Federal Home Loan Mortgage Corporation (“Freddie Mac”) or the Federal National Mortgage Association (“Fannie Mae”) (collectively, “Agency mortgage-backed securities”). Agency mortgage-backed securities may include forward contracts for Agency mortgage-backed securities purchases or sales of a generic pool, on a to-be-announced basis. TBA securities without intent to accept delivery (“TBA derivatives”) are accounted for as derivatives as discussed in the “Derivative Instruments” Note. CRT Securities - CRT securities are risk sharing instruments issued by Fannie Mae and Freddie Mac, and similarly structured transactions arranged by third party market participants. CRT securities are designed to synthetically transfer mortgage credit risk from Fannie Mae and Freddie Mac to private investors. Non-Agency Mortgage-Backed Securities - The Company invests in non-Agency mortgage-backed securities such as those issued in prime loan, prime jumbo loan, Alt-A loan, subprime loan, non-performing loan (“NPL”) and re-performing loan (“RPL”) securitizations. Agency mortgage-backed securities, non-Agency mortgage-backed securities and residential CRT securities are referred to herein as “Residential Securities.” Although the Company generally intends to hold most of its Residential Securities until maturity, it may, from time to time, sell any of its Residential Securities as part of the overall management of its portfolio. Commercial Mortgage-Backed Securities (“Commercial Securities”) - The Company invests in Commercial Securities such as conduit, credit CMBS, single-asset single borrower and collateralized loan obligations.

The decline in value of these securities is solely due to market conditions and not the quality of the assets. Substantially all of the Agency mortgage-backed securities have an actual or implied credit rating that is the same as that of the U.S. government. An impairment has not been recognized in earnings related to these investments because the decline in value is not related to credit quality, the Company currently has not made a decision to sell the securities nor is it more likely than not that the securities will be required to be sold before recovery. During the three months ended March 31, 2023 and 2022, the Company disposed of $5.2 billion and $2.8 billion of Residential Securities, respectively. The following table presents the Company’s net gains (losses) from the disposal of Residential Securities for the three months ended March 31, 2023 and 2022.

SEC Schedule, 12-29, Real Estate Companies, Investment in Mortgage Loans on Real Estate [Abstract]
LOANS	6. LOANS The Company invests in residential loans. Loans are classified as either held for investment or held for sale. Loans are eligible to be accounted for under the fair value option. If loans are elected under the fair value option, they are carried at fair value with changes in fair value recognized in earnings. Otherwise, loans held for investment are carried at cost less impairment and loans held for sale are accounted for at the lower of cost or fair value. Excluding loans transferred or pledged to securitization vehicles and loan warehouse facilities, as of March 31, 2023 and December 31, 2022, the Company rep orted $1.6 billion and $1.8 billion, respectively, of loans for which the fair value option was elected. If the Company intends to sell or securitize the loans and the securitization vehicle is not expected to be consolidated, the loans are classified as held for sale. If loans are held for sale and the fair value option was not elected, they are accounted for at the lower of cost or fair value. Any origination fees and costs or purchase premiums or discounts are deferred and recognized upon sale. The Company determines the fair value of loans held for sale on an individual loan basis. The carrying value of the Company’s residential loans held for sale was $1.2 million and $1.3 million at March 31, 2023 and December 31, 2022, respectively. Allowance for Losses – Prior to the sale of its corporate debt and commercial loan portfolios, the Company evaluated the need for a loss reserve on each of its loans classified as held-for investment and carried at amortized cost based upon estimated current expected credit losses. The Company recorded net loan loss (provisions) reversals of $0.2 million and ($0.6) million for the three months ended March 31, 2023 and 2022, respectively. The following table presents the activity of the Company’s loan investments, excluding loans transferred or pledged to securitization vehicles and loan warehouse facilities, for the three months ended March 31, 2023: Residential (dollars in thousands) Beginning balance January 1, 2023 $ 1,809,832 Purchases / originations 927,497 Sales and transfers (1) (1,091,342) Principal payments (23,526) Gains / (losses) 21,820 (Amortization) / accretion (1,459) Ending balance March 31, 2023 $ 1,642,822 (1) Includes transfer of residential loans to securitization vehicles with a carrying value of $1.1 billion during the three months ended March 31, 2023. Residential The Company’s residential mortgage loans are primarily comprised of performing adjustable-rate and fixed-rate whole loans. The Company’s residential loans are accounted for under the fair value option with changes in fair value reflected in Net gains (losses) on investments and other in the Consolidated Statements of Comprehensive Income (Loss). The Company also consolidates securitization trusts in which it had purchased subordinated securities because it also has certain powers and rights to direct the activities of such trusts. Refer to the “Variable Interest Entities” Note for further information related to the Company’s consolidated residential mortgage loan trusts. The mortgage loans are secured by first liens on primarily one-to-four family residential properties. A subsidiary of the Company has engaged a third party to act as its custodian, agent and bailee for the purposes of receiving and holding certain documents, instruments and papers related to the residential mortgage loans it purchases. Pursuant to the Company’s custodial agreement, the custodian segregates and maintains continuous custody of all documents constituting the mortgage file with respect to each mortgage loan owned by the subsidiary in secure and fire resistant facilities and in a manner consistent with the standard of care employed by prudent mortgage loan document custodians. At or prior to the funding of any residential mortgage loan, the related seller, pursuant to the terms of our mortgage loan purchase agreement, must deliver to the custodian, the mortgage loan documents including the mortgage note, the mortgage and other related loan documents. In addition, a complete credit file for the related mortgage and borrower must be delivered to the subsidiary prior to the date of purchase. The following table presents the fair value and the unpaid principal balances of the residential mortgage loan portfolio, including loans transferred or pledged to securitization vehicles and excluding loan warehouse facilities, at March 31, 2023 and December 31, 2022: March 31, 2023 December 31, 2022 (dollars in thousands) Fair value $ 11,920,410 $ 10,931,744 Unpaid principal balance $ 12,978,189 $ 12,247,346 The following table provides information regarding the line items and amounts recognized in the Consolidated Statements of Comprehensive Income (Loss) for the three months ended March 31, 2023 and 2022 for these investments, excluding loan warehouse facilities: For the Three Months Ended March 31, 2023 March 31, 2022 (dollars in thousands) Interest income $ 147,231 $ 73,465 Net gains (losses) on disposal of investments (1) (776) (7,338) Net unrealized gains (losses) on instruments measured at fair value through earnings (1) 260,441 (415,248) Total included in net income (loss) $ 406,896 $ (349,121) (1) These amounts are presented in the line item Net gains (losses) on investments and other on the Consolidated Statements of Comprehensive Income (loss).

The Company participates in an arrangement that provides a residential mortgage loan warehouse facility to a third-party originator. The Company has elected to apply the fair value option to this lending facility in order to simplify the accounting and keep the accounting consistent with other residential credit financial instruments with similar characteristics. At both March 31, 2023 and December 31, 2022, the fair value and carrying value of this warehouse facility was approximately $0.0 million and reported as Loans, net in the Consolidated Statements of Financial Condition. As of March 31, 2023, the lending facility was not on nonaccrual status nor past due. Corporate Debt In April 2022, the Company entered into a definitive agreement to sell substantially all of the corporate loan interests held by the MML business operated by the Company, as well as assets managed for third parties. All of the assets comprising the MML Portfolio were transferred by the end of 2022. Refer to the “Sale of Middle Market Lending Portfolio” Note for additional information on the transaction.

Transfers and Servicing [Abstract]
MORTGAGE SERVICING RIGHTS	7. MORTGAGE SERVICING RIGHTS MSR represent the rights and obligations associated with servicing pools of residential mortgage loans. The Company and its subsidiaries do not originate or directly service residential mortgage loans. Rather, these activities are carried out by duly licensed subservicers who perform substantially all servicing functions for the loans underlying the MSR. The Company generally intends to hold the MSR as investments and elected to account for all of its investments in MSR at fair value. As such, they are recognized at fair value on the accompanying Consolidated Statements of Financial Condition with changes in the estimated fair value presented as a component of Net gains (losses) on investments and other in the Consolidated Statements of Comprehensive Income (Loss). Interests in MSR represent agreements to purchase all, or a component of, net servicing cash flows. A third party acted as a master servicer for the loans providing the net servicing cash flows represented by the Interests in MSR. The Company accounts for its Interests in MSR at fair value with change in fair value presented in Net gains (losses) on investments and other in the Consolidated Statements of Comprehensive Income (Loss). Cash flows received for Interests in MSR are recorded in Other, net in the Consolidated Statements of Comprehensive Income (Loss). The following tables present activity related to MSR and Interests in MSR for the three months ended March 31, 2023 and 2022: Mortgage Servicing Rights Three Months Ended March 31, 2023 March 31, 2022 (dollars in thousands) Fair value, beginning of period $ 1,748,209 $ 544,562 Purchases (1) 36,630 421,012 Change in fair value due to: Changes in valuation inputs or assumptions (2) 30,207 158,963 Other changes, including realization of expected cash flows (24,066) (15,600) Fair value, end of period $ 1,790,980 $ 1,108,937 (1) Includes adjustments to original purchase price from early payoffs, defaults, or loans that were delivered but were deemed to not be acceptable.

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	8. VARIABLE INTEREST ENTITIES The Company’s exposure to the obligations of its VIEs is generally limited to the Company’s investment in the VIEs of $1.1 billion at March 31, 2023. Assets of the VIEs may only be used to settle obligations of the VIEs. Creditors of the VIEs have no recourse to the general credit of the Company. The Company is not contractually required to provide and has not provided any form of financial support to the VIEs. No gains or losses were recognized upon consolidation of existing VIEs. Interest income and expense are recognized using the effective interest method. Multifamily Securitization In March 2020, the Company repackaged Fannie Mae guaranteed multifamily mortgage-backed securities with a principal cut-off balance of $0.5 billion and retained interest-only securities with a notional balance of $0.5 billion. At the inception of this arrangement, the Company determined that it was the primary beneficiary based upon its involvement in the design of this VIE and through the retention of a significant variable interest in the VIE. The Company elected the fair value option for the financial liabilities of this VIE in order to simplify the accounting; however, the financial assets were not eligible for the fair value option as it was not elected at purchase. During the year ended December 31, 2022, the Company deconsolidated the 2020 multifamily VIE since it sold all of its interest-only securities and no longer retains a significant variable interest in the entity. Residential Securitizations The Company also invests in residential mortgage-backed securities issued by entities that are VIEs because they do not have sufficient equity at risk for the entities to finance their activities without additional subordinated financial support from other parties. The Company is not the primary beneficiary because it does not have the power to direct the activities that most significantly impact the VIEs’ economic performance. For these entities, the Company’s maximum exposure to loss is the amortized cost basis of the securities it owns and it does not provide any liquidity arrangements, guarantees or other commitments to these VIEs. Refer to the “Securities” Note for further information on Residential Securities. OBX Trusts Residential securitizations are issued by entities generally referred to collectively as the “OBX Trusts.” These securitizations represent financing transactions which provide non-recourse financing to the Company that are collateralized by residential mortgage loans purchased by the Company. Residential securitizations closed during the year are included in the table below. Securitization Date of Closing Face Value at Closing (dollars in thousands) OBX 2023-NQM1 January 2023 $ 405,209 OBX 2023-J1 February 2023 $ 305,755 OBX 2023-NQM2 February 2023 $ 420,650 As of March 31, 2023 and December 31, 2022, a total carrying value of $8.8 billion and $7.7 billion, respectively, of bonds were held by third parties and the Company retained $1.1 billion and $1.0 billion, respectively, of MBS, which were eliminated in consolidation. The Company is deemed to be the primary beneficiary and consolidates the OBX Trusts because it has power to direct the activities that most significantly impact the OBX Trusts’ performance and holds a variable interest that could be potentially significant to these VIEs. Effective August 1, 2022, upon initial consolidation of new securitization entities, the Company elected to apply the measurement alternative for consolidated collateralized financing entities in order to simplify the accounting and valuation processes. The liabilities of these securitization entities are deemed to be more observable and are used to measure the fair value of the assets. The Company incurred $1.4 million and $3.4 million of costs during the three months ended March 31, 2023 and 2022, respectively, in connection with these securitizations that were expensed as incurred. The contractual principal amount of the OBX Trusts’ debt held by third parties was $9.9 billion and $9.0 billion at March 31, 2023 and December 31, 2022, respectively. During the three months ended March 31, 2023 and 2022, the Company recorded ($211.9) million and $298.1 million, respectively, of unrealized gains (losses) on debt held by third parties issued by OBX Trusts, which is reported in Net gains (losses) on investments and other in the Company's Consolidated Statements of Comprehensive Income (Loss). Although the residential mortgage loans have been sold for bankruptcy and state law purposes, the transfers of the residential mortgage loans to the OBX Trusts did not qualify for sale accounting and are reflected as intercompany secured borrowings that are eliminated upon consolidation. Credit Facility VIEs In connection with the sale of all of the assets that comprise the MML Portfolio, the credit facilities which provided financing for the Company’s corporate debt were paid-off and terminated during the three months ended June 30, 2022. Refer to the “Sale of Middle Market Lending Portfolio” Note for additional information on the transaction. MSR VIEs The Company owns variable interests in an entity that invests in MSR and has structured its operations, funding and capitalization into pools of assets and liabilities, each referred to as a “silo.” Owners of variable interests in a given silo are entitled to all of the returns and subjected to the risk of loss on the investments and operations of that silo and have no substantive recourse to the assets of any other silo. While the Company previously held 100% of the voting interests in this entity, in August 2017, the Company sold 100% of such interests, and entered into an agreement with the entity’s affiliated portfolio manager giving the Company the power over the silo in which it owns all of the beneficial interests. As a result, the Company is considered to be the primary beneficiary and consolidates this silo. The Company owned variable interests in entities that invested in Interests in MSR. These entities were VIEs because they did not have sufficient equity at risk to finance their activities and the Company was the primary beneficiary because it had power to remove the decision makers with or without cause and held substantially all of the variable interests in the entities. During the quarter ended September 30, 2022, the Company terminated its contracts previously classified as Interests in MSR on its Consolidated Statements of Financial Condition and purchased the underlying MSR. As a result, consolidated VIEs holding the Interests in MSR and related assets and liabilities were liquidated. No gain or loss was recognized upon deconsolidation. The underlying MSR were initially recognized at fair value and subsequent changes in fair value are recognized in earnings. Refer to the “Mortgage Servicing Rights” Note and “Fair Value Measurements” Note for further information regarding MSR. The statements of financial condition of the Company’s VIEs, excluding the multifamily securitization, credit facility VIEs and OBX Trusts as the transfers of loans or securities did not meet the criteria to be accounted for as sales, that are reflected in the Company’s Consolidated Statements of Financial Condition at March 31, 2023 and December 31, 2022 are as follows: MSR VIE March 31, 2023 December 31, 2022 Assets (dollars in thousands) Cash and cash equivalents $ 2,456 $ 2,239 Loans 1,180 1,293 Mortgage servicing rights 25 27 Other assets 1,262 1,238 Total assets $ 4,923 $ 4,797 Liabilities Payable for unsettled trades $ 2,152 $ 2,152 Other liabilities 1,352 1,409 Total liabilities $ 3,504 $ 3,561 Corporate Debt Funds The Company managed parallel funds investing in senior secured first and second lien corporate loans (the “Fund Entities”). The Fund Entities were considered VIEs because the investors did not have substantive liquidation, kick-out or participating rights. The fees that the Company earned were not considered variable interests of the VIE. The Company was not the primary beneficiary of the Fund Entities and therefore did not consolidate the Fund Entities. The corporate loans in the Fund Entities were assets managed for third parties and were part of the MML Portfolio transferred to Ares during the three months ended June 30, 2022. Refer to the “Sale of Middle Market Lending Portfolio” Note for additional information on the transaction. Residential Credit Fund The Company manages a fund investing in participations in residential mortgage loans. The residential credit fund is deemed to be a VIE because the entity does not have sufficient equity at risk to permit the legal entity to finance its activities without additional subordinated financial support provided by any parties, including equity holders, as capital commitments are not considered equity at risk. The Company is not the primary beneficiary and does not consolidate the residential credit fund as its only interest in the fund is the management and performance fees that it earns, which are not considered variable interests in the entity. As of March 31, 2023 and December 31, 2022, the Company had outstanding participating interests in residential mortgage loans of $673.4 million and $800.8 million, respectively. These transfers do not meet the criteria for sale accounting and are accounted for as secured borrowings, thus the residential loans are reported as Loans, net and the associated liability is reported as Participations issued in the Consolidated Statements of Financial Condition. The Company elected to fair value the participations issued through earnings to more accurately reflect the economics of the transfers as the underlying loans are carried at fair value through earnings.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	10. DERIVATIVE INSTRUMENTS Derivative instruments include, but are not limited to, interest rate swaps, options to enter into interest rate swaps (“swaptions”), TBA derivatives, options on TBA securities (“MBS options”), U.S. Treasury and Eurodollar futures contracts and certain forward purchase commitments. The Company may also enter into other types of mortgage derivatives such as interest-only securities, credit derivatives referencing the commercial mortgage-backed securities index and synthetic total return swaps. In connection with the Company’s investment/market rate risk management strategy, the Company economically hedges a portion of its interest rate risk by entering into derivative financial instrument contracts, which include interest rate swaps, swaptions and futures contracts. The Company may also enter into TBA derivatives, MBS options and U.S. Treasury or Eurodollar futures contracts, certain forward purchase commitments and credit derivatives to economically hedge its exposure to market risks. The purpose of using derivatives is to manage overall portfolio risk with the potential to generate additional income for distribution to stockholders. These derivatives are subject to changes in market values resulting from changes in interest rates, volatility, Agency mortgage-backed security spreads to U.S. Treasuries and market liquidity. The use of derivatives also creates exposure to credit risk relating to potential losses that could be recognized if the counterparties to these instruments fail to perform their obligations under the stated contract. Additionally, the Company may have to pledge cash or assets as collateral for the derivative transactions, the amount of which may vary based on the market value and terms of the derivative contract. In the case of market agreed coupon (“MAC”) interest rate swaps, the Company may make or receive a payment at the time of entering into such interest rate swaps, which represents fair value of these swaps, to compensate for the out of market nature of such interest rate swaps. Subsequent changes in fair value from inception of these interest rate swaps are reflected within Net gains (losses) on derivatives in the Consolidated Statements of Comprehensive Income (Loss). Similar to other interest rate swaps, the Company may have to pledge cash or assets as collateral for the MAC interest rate swap transactions. In the event of a default by the counterparty, the Company could have difficulty obtaining its pledged collateral as well as receiving payments in accordance with the terms of the derivative contracts. Derivatives are recognized as either assets or liabilities at fair value in the Consolidated Statements of Financial Condition with changes in fair value recognized in the Consolidated Statements of Comprehensive Income (Loss). The changes in the estimated fair value are presented within Net gains (losses) on derivatives. None of the Company’s derivative transactions have been designated as hedging instruments for accounting purposes. The Company also maintains collateral in the form of cash on margin with counterparties to its interest rate swaps and other derivatives. In accordance with a clearing organization’s rulebook, the Company presents the fair value of centrally cleared interest rate swaps net of variation margin pledged or received under such transactions. At March 31, 2023 and December 31, 2022, ($2.3) billion and ($3.2) billion, respectively, of variation margin was reported as an adjustment to interest rate swaps, at fair value. Interest Rate Swap Agreements – Interest rate swap agreements are the primary instruments used to mitigate interest rate risk. In particular, the Company uses interest rate swap agreements to manage its exposure to changing interest rates on its repurchase agreements by economically hedging cash flows associated with these borrowings. The Company may have outstanding interest rate swap agreements where the floating leg is linked to the London Interbank Offered Rate (“LIBOR”), the overnight index swap rate or another index. Interest rate swap agreements may or may not be cleared through a derivatives clearing organization (“DCO”). Uncleared interest rate swaps are fair valued using internal pricing models and compared to the counterparty market values. Centrally cleared interest rate swaps, including MAC interest rate swaps, are generally fair valued using the DCO’s market values. If an interest rate swap is terminated, the realized gain (loss) on the interest rate swap would be equal to the difference between the cash received or paid and fair value. Swaptions – Swaptions are purchased or sold to mitigate the potential impact of increases or decreases in interest rates. Interest rate swaptions provide the option to enter into an interest rate swap agreement for a predetermined notional amount, stated term and pay and receive interest rates in the future. The Company’s swaptions are not centrally cleared. The premium paid or received for swaptions is reported as an asset or liability in the Consolidated Statements of Financial Condition. If a swaption expires unexercised, the realized gain (loss) on the swaption would be equal to the premium received or paid. If the Company sells or exercises a swaption, the realized gain (loss) on the swaption would be equal to the difference between the cash received or the fair value of the underlying interest rate swap received and the premium paid. The fair value of swaptions are estimated using internal pricing models and compared to the counterparty market values. TBA Dollar Rolls – TBA dollar roll transactions are accounted for as a series of derivative transactions. The fair value of TBA derivatives is based on methods similar to those used to value Agency mortgage-backed securities. MBS Options – MBS options are generally options on TBA contracts, which help manage mortgage market risks and volatility while providing the potential to enhance returns. MBS options are over-the-counter traded instruments and those written on current-coupon mortgage-backed securities are typically the most liquid. MBS options are measured at fair value using internal pricing models and compared to the counterparty market values. Futures Contracts – Futures contracts are derivatives that track the prices of specific assets or benchmark rates. Short sales of futures contracts help to mitigate the potential impact of changes in interest rates on the portfolio performance. The Company maintains margin accounts which are settled daily with Futures Commission Merchants (“FCMs”). The margin requirement varies based on the market value of the open positions and the equity retained in the account. Futures contracts are fair valued based on exchange pricing. Forward Purchase Commitments – The Company may enter into forward purchase commitments with counterparties whereby the Company commits to purchasing residential mortgage loans at a particular price, provided the residential mortgage loans close with the counterparties. The counterparties are required to deliver the committed loans on a “best efforts” basis. Credit Derivatives – The Company may enter into credit derivatives referencing a commercial mortgage-backed securities index, such as the CMBX index, and synthetic total return swaps. The table below summarizes fair value information about the Company’s derivative assets and liabilities at March 31, 2023 and December 31, 2022: Derivatives Instruments March 31, 2023 December 31, 2022 Assets (dollars in thousands) Interest rate swaps $ 19,155 $ 33,006 Interest rate swaptions 210,992 256,991 TBA derivatives 167,064 17,056 Futures contracts 222 33,179 Purchase commitments 2,706 1,832 Total derivative assets $ 400,139 $ 342,064 Liabilities Interest rate swaps $ 155,801 $ 108,724 TBA derivatives 3,918 69,270 Futures contracts 293,840 11,919 Purchase commitments 470 460 Credit derivatives (1) 19,486 13,799 Total derivative liabilities $ 473,515 $ 204,172 (1) The maximum potential amount of future payments is the notional amount of credit derivatives in which the Company sold protection of $385.0 million and $420.0 million at March 31, 2023 and December 31, 2022, respectively, plus any coupon shortfalls on the underlying tranche. As of March 31, 2023 the credit derivative tranches referencing the basket of bonds had AAA ratings and as of December 31, 2022 the credit derivative tranches referencing the basket of bonds had a range of ratings between AAA and AA .

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	11. FAIR VALUE MEASUREMENTS The Company follows fair value guidance in accordance with GAAP to account for its financial instruments and MSR that are accounted for at fair value. The fair value of a financial instrument and MSR is the amount 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. GAAP requires classification of financial instruments and MSR into a three-level hierarchy based on the priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the financial instrument and MSR fall within different levels of the hierarchy, the categorization is based on the lowest priority input that is significant to the fair value measurement of the instrument. Financial assets and liabilities recorded at fair value on the Consolidated Statements of Financial Condition or disclosed in the related notes are categorized based on the inputs to the valuation techniques as follows: Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets and liabilities in active markets. Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3 – inputs to the valuation methodology are unobservable and significant to overall fair value. The Company designates its securities as trading, available-for-sale or held-to-maturity depending upon the type of security and the Company’s intent and ability to hold such security to maturity. Securities classified as available-for-sale and trading are reported at fair value on a recurring basis. The following is a description of the valuation methodologies used for instruments carried at fair value. These methodologies are applied to assets and liabilities across the three-level fair value hierarchy, with the observability of inputs determining the appropriate level. Futures contracts are valued using quoted prices for identical instruments in active markets and are classified as Level 1. Residential Securities, interest rate swaps, swaptions and other derivatives are valued using quoted prices or internally estimated prices for similar assets using internal models. The Company incorporates common market pricing methods, including a spread measurement to the Treasury curve as well as underlying characteristics of the particular security including coupon, prepayment speeds, periodic and life caps, rate reset period and expected life of the security in its estimates of fair value. Fair value estimates for residential mortgage loans are generated by a discounted cash flow model and are primarily based on observable market-based inputs including discount rates, prepayment speeds, delinquency levels, and credit losses. Management reviews and indirectly corroborates its estimates of the fair value derived using internal models by comparing its results to independent prices provided by dealers in the securities and/or third party pricing services. Certain liquid asset classes, such as Agency fixed-rate pass-throughs, may be priced using independent sources such as quoted prices for TBA securities. Residential Securities, residential mortgage loans, interest rate swap and swaption markets, TBA derivatives and MBS options are considered to be active markets such that participants transact with sufficient frequency and volume to provide transparent pricing information on an ongoing basis. The liquidity of the Residential Securities, residential mortgage loans, interest rate swaps, swaptions, TBA derivatives and MBS options markets and the similarity of the Company’s securities to those actively traded enable the Company to observe quoted prices in the market and utilize those prices as a basis for formulating fair value measurements. Consequently, the Company has classified Residential Securities, residential mortgage loans, interest rate swaps, swaptions, TBA derivatives and MBS options as Level 2 inputs in the fair value hierarchy. The fair value of commercial mortgage-backed securities classified as available-for-sale is determined based upon quoted prices of similar assets in recent market transactions and requires the application of judgment due to differences in the underlying collateral. Consequently, commercial real estate debt investments carried at fair value are classified as Level 2. For the fair value of debt issued by securitization vehicles, refer to the “Variable Interest Entities” Note for additional information. The Company classifies its investments in MSR and Interests in MSR as Level 3 in the fair value measurements hierarchy. Fair value estimates for these investments are obtained from models, which use significant unobservable inputs in their valuations. These valuations primarily utilize discounted cash flow models that incorporate unobservable market data inputs including discount rates, prepayment rates, delinquency levels and costs to service. Model valuations are then compared to valuations obtained from third party pricing providers. Management reviews the valuations received from third party pricing providers and uses them as a point of comparison to modeled values. The valuation of MSR and Interests in MSR require significant judgment by management and the third party pricing providers. Assumptions used for which there is a lack of observable inputs may significantly impact the resulting fair value and therefore the Company’s financial statements. The following tables present the estimated fair values of financial instruments and MSR measured at fair value on a recurring basis. There were no transfers between levels of the fair value hierarchy during the periods presented.

Relevant inputs vary depending on the nature of the instrument being measured at fair value. The sensitivities of significant unobservable inputs along with interrelationships between and among the significant unobservable inputs and their impact on the fair value measurements are described below. The effect of a change in a particular assumption in the sensitivity analysis below is considered independently from changes in any other assumptions. In practice, simultaneous changes in assumptions may not always have a linear effect on the inputs discussed below. Interrelationships may also exist between observable and unobservable inputs. Such relationships have not been included in the discussion below. For each of the individual relationships described below, the inverse relationship would also generally apply. For MSR and Interests in MSR, in general, increases in the discount, prepayment or delinquency rates or in annual servicing costs in isolation would result in a lower fair value measurement. A decline in interest rates could lead to higher-than-expected prepayments of mortgages underlying the Company’s investments in MSR and Interests in MSR, which in turn could result in a decline in the estimated fair value of MSR and Interests in MSR. Refer to the “Mortgage Servicing Rights” Note for additional information, including rollforwards. The table below presents information about the significant unobservable inputs used for recurring fair value measurements for Level 3 MSR and Interests in MSR. The table does not give effect to the Company’s risk management practices that might offset risks inherent in these Level 3 investments.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	12. GOODWILL AND INTANGIBLE ASSETS Goodwill The Company’s acquisitions are accounted for using the acquisition method if the acquisition is deemed to be a business. Under the acquisition method, net assets and results of operations of acquired companies are included in the consolidated financial statements from the date of acquisition. The purchase prices are allocated to the assets acquired, including identifiable intangible assets, and the liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill. Conversely, any excess of the fair value of the net assets acquired over the purchase price is recognized as a bargain purchase gain. The Company tests goodwill for impairment on an annual basis or more frequently when events or circumstances may make it more likely than not that an impairment has occurred. If a qualitative analysis indicates that there may be an impairment, a quantitative analysis is performed. The quantitative impairment test for goodwill compares the fair value of a reporting unit with its carrying value, including goodwill. If the carrying value of a reporting unit exceeds its fair value, an impairment loss is recognized in amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. At March 31, 2023 and December 31, 2022, there was no goodwill balance. Intangible assets, net Finite life intangible assets are amortized over their expected useful lives. As part of the Company’s management internalization transaction, which closed on June 30, 2020, the Company recognized an intangible asset for the acquired assembled workforce of approximately $41.2 million based on the replacement cost of the employee base acquired by the Company. The following table presents the activity of finite lived intangible assets for the three months ended March 31, 2023.

SECURED FINANCING	13. SECURED FINANCING Reverse Repurchase and Repurchase Agreements – The Company finances a significant portion of its assets with repurchase agreements. At the inception of each transaction, the Company assessed each of the specified criteria in ASC 860, Transfers and Servicing , and has determined that each of the financing agreements should be treated as a secured financing. The Company enters into reverse repurchase agreements to earn a yield on excess cash balances. To mitigate credit exposure, the Company monitors the market value of these securities and delivers or obtains additional collateral based on changes in market value of these securities. Generally, the Company receives or posts collateral with a fair value approximately equal to or greater than the value of the secured financing. Reverse repurchase agreements and repurchase agreements with the same counterparty and the same maturity are presented net in the Consolidated Statements of Financial Condition when the terms of the agreements meet the criteria to permit netting. The Company reports cash flows on repurchase agreements as financing activities and cash flows on reverse repurchase agreements as investing activities in the Consolidated Statements of Cash Flows.

INCOME TAXES

INCOME TAXES	3 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	17. INCOME TAXES For the three months ended March 31, 2023, the Company was qualified to be taxed as a REIT under Code Sections 856 through 860. As a REIT, the Company will not incur federal income tax to the extent that it distributes its taxable income to its stockholders. To maintain qualification as a REIT, the Company must distribute at least 90% of its annual REIT taxable income to its stockholders and meet certain other requirements that relate to, among other things, assets it may hold, income it may generate and its stockholder composition. It is generally the Company’s policy to distribute 100% of its REIT taxable income. To the extent there is any undistributed REIT taxable income at the end of a year, the Company distributes such shortfall within the next year as permitted by the Code. The Company and certain of its direct and indirect subsidiaries, including Annaly TRS, Inc. and certain subsidiaries of joint ventures, have made separate joint elections to treat these subsidiaries as TRSs. As such, each of these TRSs is taxable as a domestic C corporation and subject to federal, state and local income taxes based upon their taxable income. The provisions of ASC 740, Income Taxes (“ASC 740”), clarify the accounting for uncertainty in income taxes recognized in financial statements and prescribe a recognition threshold and measurement attribute for uncertain tax positions taken or expected to be taken on a tax return. ASC 740 also requires that interest and penalties related to unrecognized tax benefits be recognized in the financial statements. The Company does not have any unrecognized tax benefits that would affect its financial position. Thus, no accruals for penalties and interest were deemed necessary at March 31, 2023 and December 31, 2022. The state and local tax jurisdictions for which the Company is subject to tax-filing obligations recognize the Company’s status as a REIT, and therefore, the Company generally does not pay income tax in such jurisdictions. The Company may, however, be subject to certain minimum state and local tax filing fees as well as certain excise, franchise or business taxes. The Company’s TRSs are subject to federal, state and local taxes. During the three months ended March 31, 2023 and 2022, the Company recorded $11.0 million and $26.5 million, respectively, of income tax expense (benefit) attributable to its TRSs. The Company’s federal, state and local tax returns from 2019 and forward remain open for examination.

RISK MANAGEMENT

RISK MANAGEMENT	3 Months Ended

Risk Management [Abstract]
RISK MANAGEMENT	18. RISK MANAGEMENT The primary risks to the Company are capital, liquidity and funding risk, investment/market risk, credit risk and operational risk. Interest rates are highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond the Company’s control. Changes in the general level of interest rates can affect net interest income, which is the difference between the interest income earned on interest earning assets and the interest expense incurred in connection with the interest bearing liabilities, by affecting the spread between the interest earning assets and interest bearing liabilities. Changes in the level of interest rates can also affect the value of the interest earning assets and the Company’s ability to realize gains from the sale of these assets. A decline in the value of the interest earning assets pledged as collateral for borrowings under repurchase agreements and derivative contracts could result in the counterparties demanding additional collateral or liquidating some of the existing collateral to reduce borrowing levels. The Company may seek to mitigate the potential financial impact by entering into interest rate agreements such as interest rate swaps, interest rate swaptions and other hedges. Weakness in the mortgage market, the shape of the yield curve, changes in the expectations for the volatility of future interest rates and deterioration of financial conditions in general may adversely affect the performance and market value of the Company’s investments. This could negatively impact the Company’s book value. Furthermore, if many of the Company’s lenders are unwilling or unable to provide additional financing, the Company could be forced to sell its investments at an inopportune time when prices are depressed. The Company has established policies and procedures for mitigating risks, including conducting scenario and sensitivity analyses and utilizing a range of hedging strategies. The payment of principal and interest on the Freddie Mac and Fannie Mae Agency mortgage-backed securities, which exclude CRT securities issued by Freddie Mac and Fannie Mae, is guaranteed by those respective agencies and the payment of principal and interest on Ginnie Mae Agency mortgage-backed securities is backed by the full faith and credit of the U.S. government. The Company faces credit risk on the portions of its portfolio which are not guaranteed by the respective Agency or by the full faith and credit of the U.S. government. The Company is exposed to credit risk on commercial mortgage-backed securities, residential mortgage loans, CRT securities, and other non-Agency mortgage-backed securities. MSR values may also be adversely impacted by rising borrower delinquencies which would reduce servicing income and increase overall costs to service the underlying mortgage loans. The Company is exposed to risk of loss if an issuer, borrower or counterparty fails to perform its obligations under contractual terms. The Company has established policies and procedures for mitigating credit risk, including reviewing and establishing limits for credit exposure, limiting transactions with specific counterparties, pre-purchase due diligence, maintaining qualifying collateral and continually assessing the creditworthiness of issuers, borrowers and counterparties, credit rating monitoring and active servicer oversight. The Company depends on third-party service providers to perform various business processes related to its operations, including mortgage loan servicers and sub-servicers. The Company’s vendor management policy establishes procedures for

Leases [Abstract]
LEASE COMMITMENTS AND CONTINGENCIES	19. LEASE COMMITMENTS AND CONTINGENCIES The Company’s operating leases are primarily comprised of corporate office leases with remaining lease terms of approximately two years and five years, respectively. The corporate office leases include options to extend for up to five years, however the extension terms were not included in the operating lease liability calculation. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. The lease cost for the three months ended March 31, 2023 and 2022 was $0.8 million and $0.8 million, respectively. Supplemental information related to leases as of and for the three months ended March 31, 2023 was as follows: Operating Leases Classification March 31, 2023 Assets (dollars in thousands) Operating lease right-of-use assets Other assets $ 8,165 Liabilities Operating lease liabilities (1) Other liabilities $ 10,367 Lease term and discount rate Weighted average remaining lease term 2.7 years Weighted average discount rate (1) 3.2% Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases $ 1,005 (1) For the Company’s leases that do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at adoption date in determining the present value of lease payments. The following table provides details related to maturities of lease liabilities: Maturity of Lease Liabilities Years ending December 31, (dollars in thousands) 2023 (remaining) $ 3,076 2024 4,107 2025 3,149 2026 261 2027 269 Later years 22 Total lease payments $ 10,884 Less imputed interest 517 Present value of lease liabilities $ 10,367 Contingencies From time to time, the Company is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material effect on the Company’s consolidated financial statements. There were no material contingencies at March 31, 2023 and December 31, 2022.

SIGNIFICANT ACCOUNTING POLICI_2

SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements and related notes of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”).
Principles of Consolidation	Principles of Consolidation – The consolidated financial statements include the accounts of the entities where the Company has a controlling financial interest. In order to determine whether the Company has a controlling financial interest, it first evaluates whether an entity is a voting interest entity (“VOE”) or a variable interest entity (“VIE”). All intercompany balances and transactions have been eliminated in consolidation.
Voting Interest Entities	Voting Interest Entities – A VOE is an entity that has sufficient equity and in which equity investors have a controlling financial interest. The Company consolidates VOEs where it has a majority of the voting equity of such VOE.
Variable Interest Entities	Variable Interest Entities – A VIE is defined as an entity in which equity investors (i) do not have the characteristics of a controlling financial interest, and/or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. A VIE is required to be consolidated by its primary beneficiary, which is defined as the party that has both (i) the power to control the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE causes the Company’s consolidation conclusion to change. Refer to the “Variable Interest Entities” Note for further information.
Equity Method Investments	Equity Method Investments - For entities that are not consolidated, but where the Company has significant influence over the operating or financial decisions of the entity, the Company accounts for the investment under the equity method of accounting. In accordance with the equity method of accounting, the Company will recognize its share of earnings or losses of the investee in the period in which they are reported by the investee. The Company also considers whether there are any indicators of other-than-temporary impairment of joint ventures accounted for under the equity method. These investments are included in Other assets with income or loss included in Other, net.
Cash and Cash Equivalents	Cash and Cash Equivalents – Cash and cash equivalents include cash on hand, cash held in money market funds on an overnight basis and cash pledged as collateral with counterparties. Cash deposited with clearing organizations is carried at cost, which approximates fair value.
Fair Value Measurements and the Fair Value Option	Fair Value Measurements and the Fair Value Option – The Company reports various investments at fair value, including certain eligible financial instruments elected to be accounted for under the fair value option (“FVO”). The Company chooses to elect the FVO in order to simplify the accounting treatment for certain financial instruments. Items for which the FVO has been elected are presented at fair value in the Consolidated Statements of Financial Condition and any change in fair value is recorded in Net gains (losses) on investments and other in the Consolidated Statements of Comprehensive Income (Loss). For additional information regarding financial instruments for which the Company has elected the FVO refer to the table in the “Financial Instruments” Note. Refer to the “Fair Value Measurements” Note for a complete discussion on the methodology utilized by the Company to estimate the fair value of certain financial instruments. The Company follows fair value guidance in accordance with GAAP to account for its financial instruments and MSR that are accounted for at fair value. The fair value of a financial instrument and MSR is the amount 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. GAAP requires classification of financial instruments and MSR into a three-level hierarchy based on the priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the financial instrument and MSR fall within different levels of the hierarchy, the categorization is based on the lowest priority input that is significant to the fair value measurement of the instrument. Financial assets and liabilities recorded at fair value on the Consolidated Statements of Financial Condition or disclosed in the related notes are categorized based on the inputs to the valuation techniques as follows: Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets and liabilities in active markets. Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3 – inputs to the valuation methodology are unobservable and significant to overall fair value.
Offsetting Assets and Liabilities	Offsetting Assets and Liabilities - The Company elected to present all derivative instruments on a gross basis as discussed in the “Derivative Instruments” Note. Reverse repurchase and repurchase agreements are presented net in the Consolidated Statements of Financial Condition if they meet the offsetting criteria. Refer to the “Secured Financing” Note for further discussion on reverse repurchase and repurchase agreements.
Derivative Instruments	Derivative Instruments – Derivatives are recognized as either assets or liabilities at fair value in the Consolidated Statements of Financial Condition with changes in fair value recognized in the Consolidated Statements of Comprehensive Income (Loss). The changes in the estimated fair value are presented within Net gains (losses) on derivatives. None of the Company’s derivative transactions have been designated as hedging instruments for accounting purposes. Refer to the “Derivative Instruments” Note for further discussion.
Stock-Based Compensation	Stock-Based Compensation – The Company measures compensation expense for stock-based awards at fair value, which is generally based on the grant-date fair value of the Company’s common stock. Compensation expense is recognized ratably over the vesting or requisite service period of the award. Stock-based awards that contain market-based conditions are valued using a model.
Interest Income	Interest Income - The Company recognizes interest income primarily on Residential Securities (as defined in the “Securities” Note), residential mortgage loans, commercial investments and reverse repurchase agreements. Interest accrued but not received is recognized as Interest receivable on the Consolidated Statements of Financial Condition. Interest income is presented as a separate line item on the Consolidated Statements of Comprehensive Income (Loss). For its securities, the Company recognizes coupon income, which is a component of interest income, based upon the outstanding principal amounts of the financial instruments and their contractual terms. In addition, the Company amortizes or accretes premiums or discounts into interest income for its Agency mortgage-backed securities (other than interest-only securities, multifamily and reverse mortgages), taking into account estimates of future principal prepayments in the calculation of the effective yield. The Company recalculates the effective yield as differences between anticipated and actual prepayments occur. Using third party model and market information to project future cash flows and expected remaining lives of securities, the effective interest rate determined for each security is applied as if it had been in place from the date of the security’s acquisition. The amortized cost of the security is then adjusted to the amount that would have existed had the new effective yield been applied since the acquisition date, which results in a cumulative premium amortization adjustment in each period. The adjustment to amortized cost is offset with a charge or credit to interest income. Changes in interest rates and other market factors will impact prepayment speed projections and the amount of premium amortization recognized in any given period. Premiums or discounts associated with the purchase of Agency interest-only securities, reverse mortgages and residential credit securities are amortized or accreted into interest income based upon current expected future cash flows with any adjustment to yield made on a prospective basis. Premiums or discounts associated with the purchase of multifamily securities are amortized or accreted into interest income based upon their contractual payment terms. If a prepayment occurs, an adjustment is made to the unpaid principal balance and unamortized premium or discount in the current period and the original effective yield continues to be applied. Premiums and discounts associated with the purchase of residential mortgage loans and with those transferred or pledged to securitization trusts are primarily amortized or accreted into interest income over their estimated remaining lives using the effective interest rates inherent in the estimated cash flows from the mortgage loans. Amortization of premiums and accretion of discounts are presented in Interest income in the Consolidated Statements of Comprehensive Income (Loss). If collection of a loan’s principal or interest is in doubt or the loan is 90 days or more past due, interest income is not accrued. For nonaccrual status loans carried at fair value or held for sale, interest is not accrued but is recognized on a cash basis. For nonaccrual status loans carried at amortized cost, if collection of principal is not in doubt but collection of interest is in doubt, interest income is recognized on a cash basis. If collection of principal is in doubt, any interest received is applied against principal until collectability of the remaining balance is no longer in doubt; at that point, any interest income is recognized on a cash basis. Generally, a loan is returned to accrual status when the borrower has resumed paying the full amount of the scheduled contractual obligation, if all principal and interest amounts contractually due are reasonably assured of repayment within a reasonable period of time and there is a sustained period of repayment performance by the borrower. The Company has made an accounting policy election not to measure an allowance for loans losses for accrued interest receivable. If interest receivable is deemed to be uncollectible or not collected within 90 days of its contractual due date for commercial loans or 120 days for corporate debt carried at amortized cost, it is written off through a reversal of interest income. Any interest written off that is recovered is recognized as interest income. Refer to the “Interest Income and Interest Expense” Note for further discussion of interest income.
Income Taxes	Income Taxes – The Company has elected to be taxed as a REIT and intends to comply with the provisions of the Code, with respect thereto. As a REIT, the Company will not incur federal income tax to the extent that it distributes its taxable income to its stockholders. The Company and certain of its direct and indirect subsidiaries have made separate joint elections to treat these subsidiaries as taxable REIT subsidiaries (“TRSs”). As such, each of these TRSs is taxable as a domestic C corporation and subject to federal, state and local income taxes based upon its taxable income. Refer to the “Income Taxes” Note for further discussion on income taxes.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates (“ASUs”). There were no recent ASUs that are expected to have a significant impact on the Company’s consolidated financial statements when adopted or that had a significant impact on the Company’s consolidated financial statements upon adoption.
Allowance for Losses	Allowance for Losses – Prior to the sale of its corporate debt and commercial loan portfolios, the Company evaluated the need for a loss reserve on each of its loans classified as held-for investment and carried at amortized cost based upon estimated current expected credit losses. The Company recorded net loan loss (provisions) reversals of $0.2 million and ($0.6) million for the three months ended March 31, 2023 and 2022, respectively.
Residential Mortgage Loans	The Company’s residential mortgage loans are primarily comprised of performing adjustable-rate and fixed-rate whole loans. The Company’s residential loans are accounted for under the fair value option with changes in fair value reflected in Net gains (losses) on investments and other in the Consolidated Statements of Comprehensive Income (Loss). The Company also consolidates securitization trusts in which it had purchased subordinated securities because it also has certain powers and rights to direct the activities of such trusts. Refer to the “Variable Interest Entities” Note for further information related to the Company’s consolidated residential mortgage loan trusts. The mortgage loans are secured by first liens on primarily one-to-four family residential properties. A subsidiary of the Company has engaged a third party to act as its custodian, agent and bailee for the purposes of receiving and holding certain documents, instruments and papers related to the residential mortgage loans it purchases. Pursuant to the Company’s custodial agreement, the custodian segregates and maintains continuous custody of all documents constituting the mortgage file with respect to each mortgage loan owned by the subsidiary in secure and fire resistant facilities and in a manner consistent with the standard of care employed by prudent mortgage loan document custodians. At or prior to the funding of any residential mortgage loan, the related seller, pursuant to the terms of our mortgage loan purchase agreement, must deliver to the custodian, the mortgage loan documents including the mortgage note, the mortgage and other related loan documents. In addition, a complete credit file for the related mortgage and borrower must be delivered to the subsidiary prior to the date of purchase.
Fair Value of Financial Instruments	The Company designates its securities as trading, available-for-sale or held-to-maturity depending upon the type of security and the Company’s intent and ability to hold such security to maturity. Securities classified as available-for-sale and trading are reported at fair value on a recurring basis. The following is a description of the valuation methodologies used for instruments carried at fair value. These methodologies are applied to assets and liabilities across the three-level fair value hierarchy, with the observability of inputs determining the appropriate level. Futures contracts are valued using quoted prices for identical instruments in active markets and are classified as Level 1. Residential Securities, interest rate swaps, swaptions and other derivatives are valued using quoted prices or internally estimated prices for similar assets using internal models. The Company incorporates common market pricing methods, including a spread measurement to the Treasury curve as well as underlying characteristics of the particular security including coupon, prepayment speeds, periodic and life caps, rate reset period and expected life of the security in its estimates of fair value. Fair value estimates for residential mortgage loans are generated by a discounted cash flow model and are primarily based on observable market-based inputs including discount rates, prepayment speeds, delinquency levels, and credit losses. Management reviews and indirectly corroborates its estimates of the fair value derived using internal models by comparing its results to independent prices provided by dealers in the securities and/or third party pricing services. Certain liquid asset classes, such as Agency fixed-rate pass-throughs, may be priced using independent sources such as quoted prices for TBA securities. Residential Securities, residential mortgage loans, interest rate swap and swaption markets, TBA derivatives and MBS options are considered to be active markets such that participants transact with sufficient frequency and volume to provide transparent pricing information on an ongoing basis. The liquidity of the Residential Securities, residential mortgage loans, interest rate swaps, swaptions, TBA derivatives and MBS options markets and the similarity of the Company’s securities to those actively traded enable the Company to observe quoted prices in the market and utilize those prices as a basis for formulating fair value measurements. Consequently, the Company has classified Residential Securities, residential mortgage loans, interest rate swaps, swaptions, TBA derivatives and MBS options as Level 2 inputs in the fair value hierarchy. The fair value of commercial mortgage-backed securities classified as available-for-sale is determined based upon quoted prices of similar assets in recent market transactions and requires the application of judgment due to differences in the underlying collateral. Consequently, commercial real estate debt investments carried at fair value are classified as Level 2. For the fair value of debt issued by securitization vehicles, refer to the “Variable Interest Entities” Note for additional information.
Goodwill and Intangible Assets	The Company’s acquisitions are accounted for using the acquisition method if the acquisition is deemed to be a business. Under the acquisition method, net assets and results of operations of acquired companies are included in the consolidated financial statements from the date of acquisition. The purchase prices are allocated to the assets acquired, including identifiable intangible assets, and the liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill. Conversely, any excess of the fair value of the net assets acquired over the purchase price is recognized as a bargain purchase gain.The Company tests goodwill for impairment on an annual basis or more frequently when events or circumstances may make it more likely than not that an impairment has occurred. If a qualitative analysis indicates that there may be an impairment, a quantitative analysis is performed. The quantitative impairment test for goodwill compares the fair value of a reporting unit with its carrying value, including goodwill. If the carrying value of a reporting unit exceeds its fair value, an impairment loss is recognized in amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.
Secured Financing	Reverse Repurchase and Repurchase Agreements – The Company finances a significant portion of its assets with repurchase agreements. At the inception of each transaction, the Company assessed each of the specified criteria in ASC 860, Transfers and Servicing , and has determined that each of the financing agreements should be treated as a secured financing. The Company enters into reverse repurchase agreements to earn a yield on excess cash balances. To mitigate credit exposure, the Company monitors the market value of these securities and delivers or obtains additional collateral based on changes in market value of these securities. Generally, the Company receives or posts collateral with a fair value approximately equal to or greater than the value of the secured financing. Reverse repurchase agreements and repurchase agreements with the same counterparty and the same maturity are presented net in the Consolidated Statements of Financial Condition when the terms of the agreements meet the criteria to permit netting. The Company reports cash flows on repurchase agreements as financing activities and cash flows on reverse repurchase agreements as investing activities in the Consolidated Statements of Cash Flows.
Contingencies	ContingenciesFrom time to time, the Company is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material effect on the Company’s consolidated financial statements.
