AGNC INVESTMENT CORP.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1. Unaudited Interim Consolidated Financial StatementsOrganization
The unaudited interim consolidated financial statements of AGNC Investment Corp. (referred throughout this report as the "Company," "we," "us" and "our") are prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. The preparation of 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 income and expenses during the reporting period. Actual results could differ from those estimates.
Our unaudited interim consolidated financial statements include the accounts of all of our wholly-owned subsidiaries and variable interest entities for which we are the primary beneficiary. Significant intercompany accounts and transactions have been eliminated. In the opinion of management, all adjustments, consisting solely of normal recurring accruals, necessary for the fair presentation of financial statements for the interim period have been included. The current period’s results of operations are not necessarily indicative of results that ultimately may be achieved for the year.

Note 2. Organization
We werewas organized in Delaware on January 7, 2008 and commenced operations on May 20, 2008 following the completion of our initial public offering. Our common stock is traded on The NASDAQNasdaq Global Select Market under the symbol "AGNC."
We operate so asare a leading provider of private capital to qualify to be taxed as athe U.S. housing market, enhancing liquidity in the residential real estate investment trust ("REIT") undermortgage markets and, in turn, facilitating home ownership in the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"). As a REIT, we are required to distribute annually 90% of our taxable income. As long as we continue to qualify as a REIT, we will generally not be subject to U.S. federal or state corporate taxes on our taxable income to the extent that we distribute our annual taxable income to our stockholders on a timely basis. It is our intention to distribute 100% of our taxable income, after application of available tax attributes, within the limits prescribed by the Internal Revenue Code, which may extend into the subsequent tax year.
We earn incomeinvest primarily from investing in Agency residential mortgage-backed securities ("Agency RMBS") for which the principal and interest payments are guaranteed by a U.S. Government-sponsored enterprise ("GSE") or a U.S. Government agency ("Agency RMBS") on a leveraged basis.agency. We may also invest in other types of mortgage and mortgage-related securities, such as credit risk transfer ("CRT") securities and non-Agency residential and commercial mortgage-backed securities ("non-Agency RMBS" and "CMBS," respectively), where repayment of principal and interest is not guaranteed by a U.S. Government-sponsored enterpriseGSE or U.S. Government agency.agency, and other assets related to the housing, mortgage or real estate markets.

Note 3.2. Summary of Significant Accounting Policies
Basis of Presentation
Our accompanying consolidated financial statements and related notes have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. The accompanying consolidated financial statements and related notes are unaudited and include the accounts of all our wholly-owned subsidiaries and variable interest entities for which we are the primary beneficiary. Significant intercompany accounts and transactions have been eliminated. The accompanying consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in our most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2023.
The preparation of 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 consolidated financial statements and the reported amounts of income and expenses during the reporting period. In the opinion of management, all adjustments, consisting solely of normal recurring accruals, necessary for the fair presentation of consolidated financial statements for the interim period have been included. The current period’s results of operations are not necessarily indicative of results that ultimately may be achieved for the year. 
Investment Securities
The Agency RMBS in which we invest consist of residential mortgage pass-through securities and collateralized mortgage obligations ("CMOs") guaranteed by the Federal National Mortgage Association ("Fannie Mae"), Federal Home Loan Mortgage Corporation ("Freddie Mac"Mac," and together with Fannie Mae, the "GSEs") or the Government National Mortgage Association ("Ginnie Mae") (collectively referred to as "GSEs").
CRT securities are risk sharing instruments issued by the GSEs, and similarly structured transactions issued by third partythird-party market participants, that synthetically transfer a portion of the risk associated with credit losses within pools of conventional residential mortgage


loans from the GSEs and/or third parties to private investors. Unlike Agency RMBS, full repayment of the original principal balance of CRT securities is not guaranteed by a GSE or other governmentU.S. Government agency; rather, "credit risk transfer" is achieved by writing down the outstanding principal balance of the CRT securities if credit losses on a related pool

of loans exceed certain thresholds. By reducing the amount that they are obligated to repay to holders of CRT securities, the GSEs and/or other third parties are able to offset credit losses on the related loans.
Non-Agency RMBS and CMBS (together, "Non-Agency MBS") are backed by residential and commercial mortgage loans, respectively, packaged and securitized by a private institution, such as a commercial bank. Non-Agency MBS typically benefit from credit enhancements derived from structural elements, such as subordination, overcollateralizationover-collateralization or insurance, but nonetheless carry a higher level of credit exposure than Agency RMBS.
Mortgage-relatedAll of our securities may also include investments in the common stock of other publicly traded mortgage REITs, including MTGE, which invest in Agency and non-Agency securities and/or other real estate related assets. As of September 30, 2017,are reported at fair value on our investments in REIT equity securities consisted solely of MTGE common stock.
consolidated balance sheet. Accounting Standards Codification ("ASC") Topic 320, Investments—Debt and Equity Securities, requires that at the time of purchase, we designate a security as held-to-maturity, available-for-sale or trading, depending on our ability and intent to hold such security to maturity. Alternatively, we may elect the fair value option of accounting for such securities pursuant to ASC Topic 825, Financial Instruments. All of our securities are reported at fair value as they have either been designated as available-for-sale or trading or we have elected the fair value option of accounting. Unrealized gains and losses on securities classified as available-for-sale are reported in accumulated other comprehensive income (loss) ("OCI"). Unrealized gains and losses on securities classified as trading or for which we elected the fair value option are reported in net income through other gain (loss) during the period in which they occur. Upon the sale of a security designated as available-for-sale, we determine the cost of the security and the amount of unrealized gains or losses to reclassify out of accumulated OCI into earnings based on the specific identification method.
Prior to fiscal year 2017, we primarily designated our investment securities as available-for-sale. On January 1, 2017, we began electing the fair value option of accounting for all investment securities newly acquired after fiscal year 2016.such date. Unrealized gains and losses on securities classified as available-for-sale are reported in accumulated other comprehensive income ("OCI"), whereas unrealized gains and losses on securities for which we elected the fair value option, or are classified as trading, are reported in net income through other gain (loss). Upon the sale of a security designated as available-for-sale, we determine the cost of the security and the amount of unrealized gain or loss to reclassify out of accumulated OCI into earnings based on the specific identification method. In our view, thisthe election of the fair value option simplifies the accounting for investment securities and more appropriately reflects the results of our operations for a particular reporting period asby presenting the fair value changes for these assets are presented in a manner consistent with the presentation and timing of the fair value changes offor our hedgingderivative instruments.
We are not permitted to change the designation of securities acquired prior to January 1, 2017; accordingly, such securities will continue to be classified asgenerally recognize gains or losses through net income on available-for-sale securities until such time as we receive full repayment of principal or we dispose ofonly if the security.
We estimatesecurity is sold; however, if the fair value of our investment securities based on a market approach using "Level 2" inputs from third-party pricing services and non-binding dealer quotes derived from common market pricing methods. Such methods incorporate, but are not limited to, reported trades and executable bid and asked prices for similar securities, benchmark interest rate curves, such as the spread to the U.S. Treasury rate and interest rate swap curves, convexity, duration and the underlying characteristics of the particular security, including coupon, periodic and life caps, rate reset period, issuer, additional credit support and expected life of the security. Refer to Note 8 for further discussion of fair value measurements.
We evaluate our investments designated as available-for-sale for other-than-temporary impairment ("OTTI") on at least a quarterly basis. The determination of whether a security is other-than-temporarily impaired may involve judgmentsdeclines below its amortized cost and assumptions based on subjective and objective factors. When a security is impaired, an OTTI is considered to have occurred if any one of the following three conditions exists as of the financial reporting date: (i) we intend to sell the security (that is, a decision has been made to sell the security), (ii)determine that it is more likely than not that we will be required toincur a realized loss on the security when we sell the security before recovery of itsasset, we will recognize the difference between the amortized cost basis or (iii)and the fair value in net income as a component of other gain (loss). We did not recognize any loss on available for sale securities through net income that we do not expect to recover the security's amortized cost basis, even ifheld as of March 31, 2024 because, as of such date, we dodid not intend to sell the security andany of them in an unrealized loss position nor was it is not more likely than not that we willwould be required to sell the security. A generalsuch securities before recovery of their amortized cost basis. Since all of our available-for-sale designated securities consist of Agency RMBS, we do not have an allowance for unidentified impairmentscredit losses. We have not recognized impairment losses on our available-for-sale securities through net income for the periods presented in a portfolio of securities is not permitted.our consolidated financial statements.
Interest Income
Interest income is accrued based on the outstanding principal amount of the investment securities and their contractual terms. Premiums or discounts associated with the purchase of Agency RMBS and non-Agency MBS of high credit quality are amortized or accreted into interest income, respectively, over the projected lives of the securities, including contractual payments and estimated prepayments, using the effective interest method in accordance with ASC Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs.
We estimate long-term prepayment speeds of our mortgage securities using a third-party service and market data. ActualThe third-party service provider estimates prepayment speeds using models that incorporate the forward yield curve, primary to secondary mortgage rate spreads, current mortgage rates, mortgage rates of the outstanding loans, age and size of the outstanding loans, loan-to-value ratios, interest rate volatility and other factors. We review the prepayment speeds estimated by the third-party service for reasonableness with consideration given to both historical prepayment speeds and current market conditions. If based on our assessment, we believe that the third-party model does not fully reflect our expectations of the current prepayment landscape we may make adjustments to the models. We review our actual and anticipated prepayment experience is reviewedon at least a quarterly basis and effective yields are recalculated when differences arise between (i) our previous estimate of future prepayments and (ii) the actual prepayments to date plusand our current estimate of future


prepayments. If the actual and estimated future prepayment experience differs from our prior estimate of prepayments, weWe are required to record an adjustment in the current period to thepremium amortization or/ discount accretion of premiums and discounts for the cumulative effect of the difference in the effective yields as if the recalculated yield had been in place as of the security's acquisition date through the reporting date.

At the time we purchase CRT securities and non-Agency MBS that are not of high credit quality, we determine an effective yield based on our estimate of the timing and amount of future cash flows and our cost basis. Our initial cash flow estimates for these investments are based on our observations of current information and events and include assumptions related to interest rates, prepayment rates, collateral call provisions, and the impact of default and severity rates on the timing and amount of credit losses. On at least a quarterly basis, we review the estimated cash flows and make appropriate adjustments based on inputs and analysis received from external sources, internal models, and our judgment regarding such inputs and other

factors. Any resulting changes in effective yield are recognized prospectively based on the current amortized cost of the investment as adjusted for credit impairment,impairments, if any.
Repurchase Agreements
We finance the acquisition of securities for our investment portfolio primarily through repurchase transactions under masteragreements with our lending counterparties. Repurchase arrangements involve the sale and a simultaneous agreement to repurchase agreements.the securities at a future date. We maintain a beneficial interest in the specific securities pledged during the term of each repurchase arrangement and we receive the related principal and interest payments. Pursuant to ASC Topic 860, Transfers and Servicing ("ASC 860"), we account for repurchase transactionsagreements as collateralized financing transactions, which are carried at their contractual amounts (cost), plus accrued interest. Our repurchase agreements typically have maturities of less than one year, but may extend up to five years or more. Interest rates on our repurchase agreements generally correspond to one, three or six month LIBOR plus or minus a fixed spread. The fair value of our repurchase agreements is assumed to equal cost as the interest rates are considered to be at market.year.
Reverse Repurchase Agreements and Obligation to Return Securities Borrowed under Reverse Repurchase Agreements
We borrow securities to cover short sales of U.S. Treasury securities through reverse repurchase transactions under our master repurchase agreements (see Derivative Instruments below). We account for these as securities borrowing transactions and recognize an obligation to return the borrowed securities at fair value on the balance sheet based on the value of the underlying borrowed securities as of the reporting date. We may also enter into reverse repurchase agreements to earn a yield on excess cash balances. The securities received as collateral in connection with our reverse repurchase agreements mitigate our credit risk exposure to counterparties. Our reverse repurchase agreements typically have maturities of 30 days or less. The fair value of our reverse repurchase agreements is assumed to equal cost as the interest rates are generally reset daily.
Derivative Instruments
We use a variety of derivative instruments to hedge a portion of our exposure to market risks, including interest rate, prepayment, extension and liquidity risks. The objective of our risk management strategy is to reduce fluctuations in net book value over a range of interest rate scenarios. In particular, we attempt to mitigate the risk of the cost of our variable rate liabilities increasing during a period of rising interest rates. The primary instruments that we use are interest rate swaps, options to enter into interest rate swaps ("swaptions"), U.S. Treasury securities and U.S. Treasury futures contracts. We also use forward contracts in the Agency RMBS "to-be-announced" market, ("TBA")or TBA securities, to invest in and finance Agency securities as well asand to periodically reduce our exposure to Agency RMBS.
We account for derivative instruments in accordance with ASC Topic 815, Derivatives and Hedging ("("ASC 815"). ASC 815 requires an entity to recognize all derivatives as either assets or liabilities in our accompanying consolidated balance sheets and to measure those instruments at fair value. None of our derivative instruments have been designated as hedging instruments for accounting purposes under the provisions of ASC 815, consequently changes in the fair value of our derivative instruments are reported in gain (loss) on derivative instruments and other securities, net in our consolidated statements of comprehensive income.
Our derivative agreements generally contain provisions that allow for netting or setting off derivative assets and liabilities with the counterparty; however, we report related assets and liabilities on a gross basis in our consolidated balance sheets. Derivative instruments in a gain position are reported as derivative assets at fair value and derivative instruments in a loss position are reported as derivative liabilities at fair value in our consolidated balance sheets. Changes in fair value of derivative instruments and periodic settlements related to our derivative instruments are recorded in gain (loss) on derivative instruments and other securities, net in our consolidated statements of comprehensive income. CashNet cash receipts from and payments related toon our derivative instruments are classified in our consolidated statements of cash flows according to the underlying nature or purpose of the derivative transaction, generally in the investing section.
The use of derivative instruments 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 contracts. Our derivative agreements require that we post or receive collateral to mitigate such risk. We also attempt to minimize our risk of loss by limiting our counterparties to major financial institutions with acceptable credit ratings, monitoring positions with individual counterparties and adjusting posted collateral as required.


Discontinuation of hedge accounting for interest rate swap agreements
Prior to fiscal year 2011, we entered into interest rate swap agreements typically with the intention of qualifying for hedge accounting under ASC 815. However, during fiscal year 2011, we elected to discontinue hedge accounting for our interest rate swaps. Upon discontinuation of hedge accounting, the net deferred loss related to our de-designated interest rate swaps remained in accumulated OCI and was reclassified from accumulated OCI into interest expense on a straight-line basis over the remaining term of each interest rate swap through December 2016.
Interest rate swap agreements
We use interest rate swaps to economically hedge the variable cash flows associated with our borrowings made under repurchase agreements. Under our interest rate swap agreements, we typically pay a fixed rate and receive a floating rate based on one, three or six-month LIBOR ("payer swaps") withbased on a short-term benchmark rate, such as the Secured Overnight Financing Rate ("SOFR") and Overnight Index Swap Rate ("OIS"). Our interest rate swaps typically have terms upfrom one to 2010 years. Our swap agreements are privately negotiated in the over−the−counter ("OTC") market.
Swap agreements entered into after May 2013interest rate swaps are centrally cleared through a registered commodities exchange. We value centrally cleared interest rate swaps using the daily settlement price, or fair value, determined by theThe clearing exchange based on a pricing model that references observable market inputs, including LIBOR, swap rates and the forward yield curve. Our centrally cleared swaps requirerequires that we post an "initial margin" amount determined by the clearing exchange, whichexchange. The initial margin amount is generally intended to be set at a level sufficient to protect the exchange from the interest rate swap's maximum estimated single-day price movement.movement and is subject to adjustment based on changes in market volatility and other factors. We also exchange daily settlements of "variation margin" based upon daily changes in fair value, as measured by the exchange. As a result of amendmentsPursuant to rules governing certain central clearing activities, which took effect January 3, 2017, the exchange ofwe recognize variation margin is a settlement of the interest rate swap, as opposed to pledged collateral. Accordingly, beginning in the first quarter of 2017 and in subsequent periods, we account for the receipt or payment of variation marginsettlements as a direct reduction toof the carrying value of the interest rate swap asset or liability. Variation margin pledged / (received) was previously reported in restricted cash and cash equivalents / (other liabilities) in our consolidated balance sheet.
We value non-centrally cleared swaps using a combination of third-party valuations obtained from pricing services and the swap counterparty. The third-party valuations are model-driven using observable inputs, including LIBOR, swap rates and the forward yield curve. We also consider both our own and our counterparties' nonperformance risk in estimating the fair value of our interest rate swaps. In considering the effect of nonperformance risk, we assess the impact of netting and credit enhancements, such as collateral postings and guarantees, and have concluded that our own and our counterparty risk is not significant to the overall valuation of these agreements.

Interest rate swaptions
We purchase interest rate swaptions to help mitigate the potential impact of larger, more rapid changes in interest rates on the performance of our investment portfolio. Interest rate swaptions provide us 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. Our swaption agreements typically provide us the option to enter into a pay-fixed rate interest rate swap ("payer swaptions"). We may also enter into swaption agreements that provide us the option to enter into a receive-fixed interest rate swap ("receiver swaptions").
Our interest rate swaption agreements are privately negotiated in the OTC market and are not subject to central clearing. The premium paid for interest rate swaptions is reported as an asset in our consolidated balance sheets. We estimate the fair value of interest rate swaptions using a combination of inputs from counterparty and third-party pricing models based on the fair value of the future interest rate swap that we have the option to enter into as well as the remaining length of time that we have to exercise the option, adjusted for non-performance risk, if any. The difference between the premium paid and the fair value of the swaption is reported in gain (loss) on derivative instruments and other securities, net in our consolidated statements of comprehensive income. If a swaption expires unexercised, the realized loss on the swaption would be equal to the premium paid. If we sell or exercise a swaption, the realized gain or loss on the swaption would be equal to the difference between the cash or the fair value of the underlying interest rate swap received and the premium paid.
TBA securities
A TBA security is a forward contract for the purchase or sale of Agency RMBS at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific Agency RMBS to be delivered into the contract are not known until shortly before the settlement date. We may choose, prior to settlement, to move the settlement of these securities out to a later date by entering into an offsetting TBA position, net settling the offsetting positions for cash, and simultaneously purchasing or selling a similar TBA contract for a later settlement date (together referred to as a "dollar roll transaction"). The Agency securities purchased or sold for a forward settlement date are typically priced at a discount to equivalent securities settling in the current month. This difference, or "price drop," is the economic equivalent toof interest income on the underlying Agency securities, less


an implied funding cost, over the forward settlement period (referred to as "dollar roll income"). Consequently, forward purchases of Agency securities and dollar roll transactions represent a form of off-balance sheet financing.
We account for TBA contracts as derivative instruments since either the TBA contracts do not settle in the shortest period of time possible or we cannot assert that it is probable at inception and throughout the term of the TBA contract that we will physically settle the TBA contract on the settlement date. We account for TBA dollar roll transactions as a series of derivative transactions. Gains, losses and dollar roll income associated with our TBA contracts are recognized in gain (loss) on derivative instruments and other securities, net in our consolidated statements of comprehensive income. We estimate the fair value of TBA securities based on similar methods used to value our Agency RMBS securities.
U.S. Treasury securities and US Treasury futures contracts
We purchase and sell shortuse U.S. Treasury securities and U.S. Treasury futures contracts to help mitigate the potential impact of changes in interest rates on the performance of our portfolio. We borrow securities to cover short salesenter into short-sales of U.S. Treasury securities by borrowing the securities under reverse repurchase agreements.agreements and selling them into the market. We account for these as securities borrowing transactions and recognize an obligation to return the borrowed securities at fair value on our accompanying consolidated balance sheets based on the value of the underlying borrowed securitiesU.S. Treasury security as of the reporting date. Treasury futures contracts are standardized contracts that obligate us to sell or buy U.S. Treasury securities for future delivery. Gains and losses associated with purchases and short sales of U.S. Treasury securities and U.S. Treasury futures contracts are recognized in gain (loss) on derivative instruments and other securities, net in our consolidated statements of comprehensive income.
Loss ContingenciesFair Value Measurements
We evaluatedetermine the existencefair value of any pendingfinancial instruments based on our estimate of the price that would be received to sell the asset or threatened litigationpaid to transfer the liability in an orderly transaction between market participants at the measurement date. We utilize a three-level valuation hierarchy for disclosure of fair value measurements based upon the transparency of inputs to the valuation of the instrument as of the measurement date. We categorize a financial instrument within the hierarchy based upon the lowest level of input that is significant to the fair value measurement.
The three levels of valuation hierarchy are defined as follows:
Level 1 Inputs —Quoted prices (unadjusted) for identical unrestricted assets and liabilities in active markets that are accessible at the measurement date.
Level 2 Inputs —Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3 Inputs —Instruments with primarily unobservable market data that cannot be corroborated.
The majority of our financial instruments are classified as Level 2 inputs. The availability of observable inputs can be affected by a wide variety of factors, including the type of instrument, whether the instrument is new and not yet established in the marketplace and other potential claims againstcharacteristics particular to the Company in accordance with ASC Topic 450, Contingencies, which requiresinstrument. We typically obtain price estimates from multiple third-

party pricing sources, such as pricing services and dealers, or, if applicable, from the registered clearing exchange. We make inquiries of third-party pricing sources to understand the significant inputs and assumptions they used to determine their prices and that we assessthey are derived from orderly transactions, particularly during periods of elevated market turbulence and reduced market liquidity. We also review third-party price estimates and perform procedures to validate their reasonableness, including an analysis of the likelihood and range of potential outcomes of any such matters. We are the defendant in two stockholder derivative lawsuits alleging that certain of our currentestimates for each position, comparison to recent trade activity for similar securities and former directors and officers breached fiduciary duties and wasted corporate assets in connectionfor consistency with past renewalsmarket conditions observed as of the management agreement with our former external Manager and the internalization of our management, which occurred on July 1, 2016. Although the outcomes of these cases cannot be predicted with certainty,measurement date. While we do not believeadjust prices we obtain from pricing sources, we will exclude prices for securities from our estimation of fair value if we determine based on our validation procedures and our market knowledge and expertise that the price is significantly different from what observable market data would indicate and we cannot obtain an understanding from the third-party source as to the significant inputs used to determine the price.
The following is a description of the valuation methodologies used for financial instruments measured at fair value on a recurring basis classified as Level 2 inputs. These instruments trade in active markets such that participants transact with sufficient frequency and volume to provide transparent pricing information on an ongoing basis. The liquidity of these cases have merit or will result inmarkets and the similarity of our instruments to those actively traded enable our pricing sources and us to utilize the observed quoted prices as a material liability,basis for formulating fair value measurements.
Investment securities - are valued based on prices obtained from multiple third-party pricing sources. The pricing sources utilize various valuation approaches, including market and income approaches. For Agency RMBS, the pricing sources primarily utilize a matrix pricing technique that interpolates the estimated fair value based on observed quoted prices for TBA securities having the same coupon, maturity and issuer, adjusted to reflect the specific characteristics of the pool of mortgages underlying the Agency security, such as maximum loan balance, loan vintage, loan-to-value ratio, geography and other characteristics as may be appropriate. For other investment securities, the pricing sources primarily utilize discounted cash flow model-derived pricing techniques to estimate the fair value. Such models incorporate market-based discount rate assumptions based on observable inputs such as recent trading activity, credit data, volatility statistics, benchmark interest rate curves, spread measurements to benchmark curves and other market data that are current as of September 30, 2017,the measurement date and may include certain unobservable inputs, such as assumptions of future levels of prepayment, defaults and loss severities.
TBA securities - are valued using prices obtained from third-party pricing sources based on pricing models that reference recent trading activity.
Interest rate swaps - are valued using the daily settlement price, or fair value, determined by the clearing exchange based on a pricing model that references observable market inputs, including current benchmark rates and the forward yield curve.
Interest rate swaptions - are valued using prices obtained from the counterparty and other third-party pricing models. The pricing models are based on the value of the future interest rate swap that we did not accrue a loss contingency relatedhave the option to these matters.enter into as well as the remaining length of time that we have to exercise the option based on observable market inputs, adjusted for non-performance risk, if any.
U.S. Treasury securities and futures are valued based on quoted prices for identical instruments in active markets and are classified as Level 1 assets. None of our financial instruments are classified as Level 3 inputs.
Recent Accounting Pronouncements
We consider the applicability and impact of all Accounting Standards Updates (“ASUs”)ASUs issued by the Financial Accounting Standards Board.FASB. There are no unadopted ASUs not listed below were determined to be either not applicable,that are not expected to have a significant impact on our consolidated financial statements when adopted or did not haveother recently adopted ASUs that had a significant impact on our consolidated financial statements upon adoption.
ASU 2014-09, Revenue from Contracts with Customers (Topic 606): ASU 2014-09 is a comprehensive revenue recognition standard that supersedes virtually all existing revenue guidance under U.S. GAAP. The standard’s core principle is that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. Revenue recognition with respect to financial instruments is not within the scope of ASU 2014-09 and our review of each of our revenue streams indicates that it will not have a significant impact on our consolidated financial statements. ASU 2014-09 is effective on January 1, 2018.
ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): ASU 2016-13 changes the impairment model for most financial assets and certain other instruments. Allowances for credit losses on available-for-sale debt securities will be recognized, rather than direct reductions in the amortized cost of the investments. The new model also requires the estimation of lifetime expected credit losses and corresponding recognition of allowance for losses on trade and other receivables, held-to-maturity debt securities, loans, and other instruments held at amortized cost. The ASU requires certain recurring disclosures and is effective for annual periods, and interim periods within those annual periods, beginning on or after December 15, 2019, with early adoption permitted for annual periods, and interim periods within those annual periods, beginning on or after December 15, 2018. ASU 2016-13 is not expected to have a significant impact on our consolidated financial statements.
ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash: ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 will be effective on January 1, 2018 and is not expected to have a significant impact on our consolidated financial statements.

Our CRT securities reference the performance of loans underlying Agency RMBS issued by Fannie Mae or Freddie Mac, which were subject to their underwriting standards. As of September 30, 2017, our CRT securities had floating rate coupons ranging from 3.7% to 7.6%, referenced to loans originated between 2012 and 2017 with weighted average coupons ranging from 3.6% to 4.3%. As of December 31, 2016, our CRT securities had floating rate coupons ranging from 4.6% to 7.1%, referenced to loans originated between 2015 and 2016 with weighted average coupons ranging from 4.0% to 4.2%.

We did not recognize any OTTI charges on our investment securities for the nine months ended September 30, 2017 and 2016. As of the end of each respective reporting period, a decision had not been made to sell any of our securities in an unrealized loss position and we did not believe it was more likely than not that we would be required to sell such securities before recovery of their amortized cost basis. The unrealized losses on our securities were not due to credit losses given the GSE guarantees, but rather were due to changes in interest rates and prepayment expectations. However, as we continue to actively manage our portfolio, we may recognize additional realized losses on our investment securities upon selecting specific securities to sell.

Securitizations and Variable Interest Entities
As of September 30, 2017 and December 31, 2016, we held investments in CMO trusts, which are variable interest entities ("VIEs"). We have consolidated certain of these CMO trusts in our consolidated financial statements where we have determined we are the primary beneficiary of the trusts. All of our CMO securities are backed by fixed or adjustable-rate Agency RMBS. Fannie Mae or Freddie Mac guarantees the payment of interest and principal and acts as the trustee and administrator of their respective securitization trusts. Accordingly, we are not required to provide the beneficial interest holders of the CMO securities any financial or other support. Our maximum exposure to loss related to our involvement with CMO trusts is the fair value of the CMO securities and interest and principal-only securities held by us, less principal amounts guaranteed by Fannie Mae and Freddie Mac.
In connection with our consolidated CMO trusts, we recognized Agency securities with a total fair value and approximate unpaid principal balance of $0.7 billion as of September 30, 2017period end.

3.During the three months ended March 31, 2024 and $0.8 billion as2023, we received principal repayments on available-for-sale securities of December 31, 2016$143 million and debt with a total fair value and approximate unpaid principal balance of $0.4 billion as of September 30, 2017 and $0.5 billion as of December 31, 2016 in our accompanying consolidated balance sheets. We re-measure our consolidated debt at fair value through earnings in gain (loss) on derivative instruments and other securities, net in our consolidated statements of comprehensive income. Our involvement with the consolidated trusts is limited to the Agency securities transferred by us upon the formation of the trusts and the CMO securities subsequently held by us. There are no arrangements that could require us to provide financial support to the trusts.$179 million, respectively.  
As of September 30, 2017 and December 31, 2016, the fair value of our CMO securities and interest and principal-only securities was $0.9 billion and $1.1 billion, respectively, excluding the consolidated CMO trusts discussed above, or $1.2 billion and $1.5 billion, respectively, including the net asset value of our consolidated CMO trusts. Our maximum exposure to loss related to our CMO securities and interest and principal-only securities, including our consolidated CMO trusts, was $149 million and $182 million as of September 30, 2017 and December 31, 2016, respectively.



Note 5.4. Repurchase Agreements and Other Secured BorrowingsReverse Repurchase Agreements
Repurchase Agreements
We pledge certain of our securities as collateral under our borrowingborrowings structured as repurchase agreements with financial institutions. Interest rates on our borrowings are generally based on LIBOR plus or minus a margin and amountsAmounts available to be borrowed are dependent upon the fair value of the securities pledged as collateral, which fluctuates with changes in interest rates, type of security and liquidity conditions within the banking, mortgage finance and real estate industries. If the fair value of our pledged securities declines, lenders will typically require us to post additional collateral or pay down borrowings to re-establish agreed upon collateral requirements, referred to as "margin calls." Similarly, if the fair value of our pledged securities increases, lenders may release collateral back to us. As of September 30, 2017,March 31, 2024, we had met all margin call requirements. For additional information regarding our pledged assets, please refer to Note 7.6.

The terms and conditions of our repurchase agreements are typically negotiated on a transaction-by-transaction basis. Our repurchase agreements with original maturities greater than 90 days have floating interest rates based on an index plusbasis or minussubject to a fixed spread.

As of March 31, 2024 and December 31, 2023, we had $95 million notional value of centrally cleared credit default swaps ("CDS") outstanding that reference the Markit CDX Investment Grade or High Yield Grade Index, maturing in December 2028. Under the terms of our CDS, we pay fixed periodic payments equal to 1% per annum of the notional value and we are entitled to receive payments for qualified credit events. As of March 31, 2024 and December 31, 2023, the CDS had a market value of $(7) million and $(6) million, respectively, and a net carrying value of zero dollars, net of variation margin settlements. Pursuant to rules governing central clearing activities, we recognize variation margin settlements as a direct reduction of the carrying value of the CDS asset or liability.

Note 7.6. Pledged Assets
Our funding agreements require us to fully collateralize our obligations under the agreements based upon our counterparties' collateral requirements and their determination of the fair value of the securities pledged as collateral, which fluctuates with changes in interest rates, credit quality and liquidity conditions within the investment banking, mortgage finance and real estate


industries. Our derivative contracts similarly require us to fully collateralize our obligations under such agreements, which will vary over time based on similar factors as well as our counterparties' determination of the value of the derivative contract. We are typically required to post initial margin upon execution of derivative transactions, such as under our interest rate swap agreements and TBA contracts, and subsequently post or receive variation margin based on daily fluctuations in fair value. Our prime brokerage agreements, pursuant to which we receiveand custody and settlement services,agreements and the clearing organizations utilized by our wholly-owned captive broker-dealer subsidiary, Bethesda Securities, LLC, also require that we post minimum daily clearing deposits. If we breach our collateral requirements, we will be required to fully settle our obligations under the agreements, which could include a forced liquidation of our pledged collateral.
Our counterparties also apply a "haircut" to our pledged collateral, which means our collateral is valued at slightly less than market value and limits the amount we can borrow against our securities. This haircut reflects the underlying risk of the specific collateral and protects our counterparty against a change in its value. Our agreements do not specify the haircut; rather, haircuts are determined on an individual transaction basis. Consequently, our funding agreements and derivative contracts expose us to credit risk relating to potential losses that could be recognized in the event thatif our counterparties fail to perform their obligations under such agreements. We minimize this risk by limiting our counterparties to major financial institutions with acceptable credit ratings or to registered clearinghouses and U.S. government agencies, and we monitor our positions with individual counterparties. In the event of a default by a counterparty, we may have difficulty obtaining our assets pledged as collateral to
18


such counterparty and may not receive payments provided foras and when due to us under the terms of our derivative agreements. In the case of centrally cleared instruments, we could be exposed to credit risk if the central clearing agency or a clearing member defaults on its respective obligation to perform under the contract. However, we believe that the risk is minimal due to the clearing exchanges' initial and daily mark to marketmark-to-market margin requirements, and clearinghouse guarantee funds and other resources that are available in the event of a clearing member default.
Our International Swaps and Derivatives Association ("ISDA") Master Agreements contain a cross default provision under which a default under certain of our other indebtedness in excess of certain thresholds causes an event of default under the ISDA Master Agreement. Threshold amounts vary by lender. Following an event of default, we could be required to settle our obligations under the agreements. Additionally, under certain of our ISDA Master Agreements, we could be required to settle our obligations under the agreements if we fail to maintain certain minimum stockholders' equity thresholds or our REIT status or if we fail to comply with limits on our leverage up to certain specified levels. As of September 30, 2017, the fair value of additional collateral that could be required to be posted as a result of the credit-risk-related contingent features being triggered was not material to our financial statements.
As of September 30, 2017, our amount at risk with any counterparty related to our repurchase agreements was less than 5% of our stockholders' equity. As of DecemberMarch 31, 2016,2024, our maximum amount at risk with any counterparty related to our repurchase agreements, excluding the Fixed Income Clearing Corporation, was 5.5%,less than 3% of our tangible stockholders' equity and(or the excess/shortfall of the value of collateral pledged/received over our maximum amountrepurchase agreement liabilities/reverse repurchase agreement receivables). As of March 31, 2024, 5% of our tangible stockholder's equity was at risk with any counterparty related to our interest rate swap and swaption agreements, excluding centrally cleared swaps, was less than 1% of our stockholders' equity. The following table summarizes certain characteristics of our repurchase agreements outstanding with counterparties representing amounts at risk greater than or equal to 5% of our stockholders' equity as of December 31, 2016 (dollars in millions).

We recognize a corresponding obligation to return the borrowed securities at fair value on the accompanying consolidated balance sheets based on the value of the underlying borrowed securities as of the reporting date.
Cash collateral received is recognized in cash and cash equivalents with a corresponding amount recognized in accounts payable and other accrued liabilities on the accompanying consolidated balance sheets.
Offsetting Assets and Liabilities
Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of setoff under master netting arrangements (or similar agreements), including in the event of default or in the event of bankruptcy of either party to the transactions. We present our assets and liabilities subject to such arrangements on a gross basis in our consolidated balance sheets. The following tables present information about our assets and liabilities that are subject to master netting arrangements and can potentially be offset on our consolidated balance sheets as of September 30, 2017March 31, 2024 and December 31, 20162023 (in millions):

Note 8.7. Fair Value Measurements
We determine the fair value of our investment securities and debt of consolidated VIEs based upon fair value estimates obtained from multiple third party pricing services and dealers.  In determining fair value, third party pricing sources use various valuation approaches, including market and income approaches.  Factors used by third party sources in estimating the fair value of an instrument may include observable inputs such as coupons, primary and secondary mortgage rates, pricing information, credit data, volatility statistics, and other market data that are current as of the measurement date. The availability of observable inputs can vary by instrument and is affected by a wide variety of factors, including the type of instrument, whether the instrument is new and not yet established in the marketplace and other characteristics particular to the instrument.  Third party pricing sources may also use certain unobservable inputs, such as assumptions of future levels of prepayment, defaults and foreclosures, especially when estimating fair values for securities with lower levels of recent trading activity. We make inquiries of third party pricing sources to understand the significant inputs and assumptions they used to determine their prices. For information regarding valuation of our derivative instruments, please refer to the discussion of derivative and other hedging instruments in Note 3. 
We review third party fair value estimates and perform procedures to validate their reasonableness, including an analysis of the range of estimates for each position, comparison to recent trade activity for similar securities, and for consistency with market conditions observed as of the measurement date. While we do not adjust prices we obtain from third party pricing sources, we will exclude third party prices for securities from our estimation of fair value if we determine (based on our validation procedures and our market knowledge and expertise) that the price is significantly different from what observable market data would indicate and we cannot obtain an understanding from the third party source as to the significant inputs used to determine the price.  
The validation procedures described above also influence our determination of the appropriate fair value measurement classification.  We utilize a three-level valuation hierarchy for disclosure of fair value measurement. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument's categorization within the hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There were no transfers between valuation hierarchy levels during the three and nine months ended September 30, 2017. The three levels of valuation hierarchy are defined as follows:
Level 1 Inputs —Quoted prices (unadjusted) for identical unrestricted assets and liabilities in active markets that are accessible at the measurement date.
Level 2 Inputs —Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3 Inputs —Instruments with primarily unobservable market data that cannot be corroborated.


The following table provides a summary of our assets and liabilities that are measured at fair value on a recurring basis, as of September 30, 2017March 31, 2024 and December 31, 20162023, based on their categorization within the valuation hierarchy (in millions):

Excluded from the table above are financial instruments includingreported at cost and other mortgage credit investments reported under the equity method of accounting in our consolidated financial statements. As of March 31, 2024 and December 31, 2023, the fair value of our repurchase agreements approximated cost, as the rates on our outstanding repurchase agreements largely corresponded to prevailing rates observed in the repo market. The fair value of cash and cash equivalents, restricted cash, receivables and cash equivalents, receivables,other payables and borrowings under repurchase agreements and FHLB advances, which are presented in our consolidated financial statements at cost. The cost basis of these instruments iswere determined to approximate fair valuecost as of such dates due to their short duration or, in the case of longer-term repo, due to floating rates of interest based on an index plus or minus a fixed spread which is consistent with fixed spreads demanded in the market.duration. We estimate the fair value of these instruments carried at cost using "Level 1" or "Level 2" inputs. As of March 31, 2024 and December 31, 2023, the carrying value of other mortgage credit investments reported under the equity method of accounting was $59 million and $44 million, respectively.


Note 9.8. Net Income (Loss) Per Common Share


Basic net income (loss) per common share includes no dilution and is computed by dividing (i) net income or (loss) applicableavailable (attributable) to common stockstockholders by (ii) the sum of our weighted-average number of common shares outstanding forand the respective period. Diluted earnings per common share includes the impactweighted-average number of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares outstanding include unvestedvested but not yet issued time and performance-based restricted stock units and performance share units("RSUs") outstanding for the period granted under our long-term incentive program to employees and non-employee Board of Directors. Diluted net income (loss) per common share assumes the issuance of all potential common stock equivalents unless the effect is to reduce a loss or increase the income per common share. Our potential common stock equivalents consist of unvested time and performance-based RSUs. The following table presents the computations of basic and diluted net income (loss) per common share for the periods indicated (shares and dollars in millions):

EXECUTIVE OVERVIEW
AGNC Investment Corp. ("AGNC," the "Company," "we," "us" and "our") is an internally managed Real Estate Investment Trust ("REIT") that was organized on January 7, 2008 and commenced operations on May 20, 2008 following the completionWe are a leading provider of our initial public offering. Our common stock is traded on The NASDAQ Global Select Market ("NASDAQ") under the symbol "AGNC."
We operate so as to qualify to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"). As such, we are required to distribute annually 90% of our taxable income. As long as we qualify as a REIT, we will generally not be subject to U.S. federal or state corporate taxes on our taxable incomeprivate capital to the extent that we distribute all of our taxable income to our stockholdersU.S. housing market, enhancing liquidity in a timely manner. It is our intention to distribute 100% of our taxable income, after application of available tax attributes, within the limits prescribed byresidential real estate mortgage markets and, in turn, facilitating home ownership in the Internal Revenue Code, which may extend into the subsequent tax year.
U.S. We earn incomeinvest primarily from investing in Agency residential mortgage-backed securities ("Agency RMBS") on a leveraged basis. These investments consist of residential mortgage pass-through securities and collateralized mortgage obligations ("CMOs") for which the principal and interest payments are guaranteed by a government-sponsoredU.S. Government-sponsored enterprise, such as the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac"Mac," and together with Fannie Mae, the "GSEs"), or by a U.S. Government agency, such as the Government National Mortgage Association ("Ginnie Mae") (collectively referred to as "GSEs"). We may also invest in other types ofassets related to the housing, mortgage and mortgage-related securities, such as credit risk transfer ("CRT") securities and non-Agency residential and commercial mortgage-backed securities ("non-Agency RMBS" and "CMBS," respectively), where repayment of principal and interest isor real estate markets that are not guaranteed by a GSE or U.S. Government agency.
OurWe are internally managed with the principal objective is to provide our stockholdersof generating favorable long-term stockholder returns with attractive risk-adjusted returns through a combination of monthly dividends and net book value (also referred to as "net asset value" or "NAV") accretion.substantial yield component. We generate income from the interest earned on our investment assets,investments, net of associated borrowing and hedging activities,costs, and net realized gains and losses on our investmentsinvestment and hedging activities. We fund our investments primarily through collateralized borrowings structured as repurchase agreements ("repo").
Prior to July 1, 2016, we were externally managed by AGNC Management, LLC (our "Manager"). On July 1, 2016, we completed the acquisition of all of the outstanding membership interests of AGNC Mortgage Management, LLC ("AMM"), the parent company of our Manager, from American Capital Asset Management, LLC,agreements. We operate in a wholly owned portfolio company of American Capital, Ltd. ("ACAS"). AMM is also the parent company of MTGE Management, LLC, the external manager of MTGE Investment Corp. ("MTGE") (NASDAQ: MTGE). Following the closing of the acquisition of AMM, we became internally managed and are no longer affiliated with ACAS.

Our Investment Strategy
Our investment strategy is designed to:
generate attractive risk-adjusted returns for our stockholders comprised of monthly dividend distributions and NAV accretion;
manage an investment portfolio consisting primarily of Agency securities;
invest a subset of the portfolio in mortgage credit risk oriented assets;

Our Risk Management Strategy
We use a variety of strategies to reduce our exposure to market risks, including interest rate, prepayment, extension, liquidity and credit risks. Our investment strategies incorporate our assessment of these risks, the cost of the hedging transactions and our intention to qualify as a REIT. Our hedging strategies are generally not designed to protect our net asset value from "spread risk" (also referred to as "basis risk"), which is the risk that the yield differential between our investments and our hedges fluctuates. In addition, while we use interest rate swaps and other supplemental hedges to attempt to protect our net asset value against moves in interest rates, we may not hedge certain interest rate, prepayment, extension or other market risks if we believe that bearing such risks enhances our return profile, or if the hedging transaction would negatively impact our REIT status.
The risk management actions we take may lower our earnings and dividends in the short term to further our objective of maintaining attractive levels of earnings and dividends over the long term. In addition, some of our hedges are intended to provide protection against larger rate moves and as a result may be relatively ineffective for smaller changes in interest rates. There can also be no certainty that our projections of our exposures to interest rates, prepayment, extension or other risks will be accurate or that our hedging activities will be effective and, therefore, actual results could differ materially. Furthermore, since our hedging strategies are generally not designed to protect our net book value from spread risk, wider spreads between the market yield on our investment securities and benchmark interests underlying our interest rate hedges will typically cause our net book value to decline and can occur independent of changes in benchmark interest rates. For further discussion of our market risks and risk management strategy, please refer to "Quantitative and Qualitative Disclosures about Market Risk" under Item 3 of this Quarterly Report on Form 10-Q.


Trends and Recent Market Impacts
The favorable macroeconomic environment for fixed income markets were relatively stable throughoutinvestors that began in late 2023 persisted through the conclusion of the first three quartersquarter of 2017 as2024. During this period, interest rate volatility declined significantly, and Agency RMBS spreads to benchmark interest rates remained extremely low. In this environment, investors continuedrelatively stable. The Federal Reserve also indicated that the peak of the interest rate tightening cycle had likely been reached and further noted that a reduction in the pace of its balance sheet runoff was probable in the near-term, signaling that an end to favor higher risk assets,the quantitative tightening process was nearing. Mortgage origination levels remained depressed as evidenceda result of seasonal factors and affordability challenges. Additionally, bank demand for Agency RMBS was unexpectedly strong, driven in part by the strongexpectation that the Basel III Endgame capital requirements, if and when finally adopted, will be less onerous on banks than originally proposed. Together, these factors, reduced mortgage originations and incremental bank demand, provided a favorable backdrop for Agency RMBS supply-demand dynamics.
The outlook for monetary policy shifted materially in April in response to stronger-than-expected economic data. Contrary to the Fed’s expectations, inflation readings showed no meaningful improvement. As a result, after a period of relative stability in the first quarter, benchmark interest rates and volatility increased sharply in April, driven by less optimistic inflation expectations and escalating geopolitical risks. In response, Agency RMBS spreads to benchmark interest rates widened modestly, causing valuations to decline.
Despite the recent volatility, the fundamental outlook for Agency RMBS remains positive. With absolute yields back above 6% as of the end of April and explicit support from the U.S. government, Agency RMBS are appealing to a broad universe of investors. Agency RMBS spreads to benchmark interest rates remain wide by historical standards, providing the opportunity for favorable risk-adjusted returns for levered Agency RMBS investors. Looking forward, if monetary policy

proceeds largely as anticipated, we would expect interest rate volatility to decline, the yield curve to steepen, and quantitative tightening to conclude. Importantly, the precise timing of Fed rate cuts is not a critical factor in our favorable long-term performance ofexpectations for Agency RMBS.
During the first quarter, the 10-year U.S. equitiesTreasury increased 32 basis points, and the tighteningcurrent coupon Agency RMBS spread to a blend of 5- and 10-year Treasuries was unchanged at 139 basis points as of March 31, 2024.
For the quarter, AGNC earned total comprehensive income of $0.48 per diluted common share and generated a total economic return of 5.7% on tangible common equity comprised of $0.36 dividends declared per common share and a $0.14 increase in spreads associated withtangible net book value per common share. These results compare to total comprehensive income of $1.00 per diluted common share and economic return of 12.1% for the prior quarter. Net spread and dollar roll income per diluted common share (a non-GAAP measure) totaled $0.58 for the first quarter, a wide rangedecline of credit-sensitive fixed income assets. In contrast,2 cents per share from the spread betweenprior quarter, as higher swap costs more than offset the increase in the average asset yield on our portfolio.
We maintained a large interest rate hedge position during the quarter, which covered 99% of the outstanding balance of Investment Securities Repo, TBA position and other debt as of the end of the quarter. This was a slight decrease from 112% as of December 31, 2023. “At risk” leverage was largely unchanged at 7.1x of our tangible stockholders’ equity as of March 31, 2024, compared to 7.0x as of December 31, 2023. Our unencumbered cash and Agency RMBS grew to $5.4 billion, or 67% of our tangible stockholders' equity, as of the end of the first quarter, up from $5.1 billion, or 66% of tangible stockholders’ equity, as of December 31, 2023. The weighted average coupon on our fixed-rate Agency RMBS and other hedge instrumentsTBA securities increased slightly to 4.86%, from 4.83%, as of the end of the quarter, as we continued to shift a larger share of our asset portfolio toward higher coupon, high-quality specified pools. Additionally, we issued $241 million of accretive common equity during the quarter through our At-the-Market offering program to capitalize on our material price to book premium.
While market turbulence may persist in the short term due to factors such as U.S. Treasuriesinflation expectations and swaps widened throughout much of the period until the Federal Reserve (the "Fed") announcedgeopolitical risks, we believe AGNC is well positioned to navigate this environment. Our active management strategy, strategic focus on September 20, 2017 that, commencing in October 2017, it will begin to taper its reinvestment of proceeds from its bond portfolio. Following the Fed's announcement,high-quality Agency RMBS spreads tightened meaningfully, outperforming interest rate hedges, benefiting our net asset valueassets, attractive funding sources, and confirming our thesis thatstrong liquidity position should allow us not only to withstand episodes of volatility but also to take advantage of attractive investment opportunities as they arise.

The strong performance of Agency RMBS, combined with the accretive impact of common equity raises, increased our tangible net book value to $19.78 per common share as of September 30, 2017, from $19.25 per common share as of June 30, 2017, an increase of 2.8% for the quarter. Year-to-date, through September 30, 2017, our tangible net book value improved 1.4%, from $19.50 per common share as of December 31, 2016. Including $1.62 of dividends paid per common share, the economic return on our tangible common equity was 9.7% for the first three quarters of the year.
The yield curve flattened during the first three quarters of 2017, as the Fed continued to gradually increase short term interest rates by raising the federal funds rate by 50 basis points. Over the same period, the 10-year yield on the U.S. Treasury declined by 10 basis points, causing the yield curve to flatten and contributing to a modest compression of our net interest margin. Inclusive of our TBA position and excluding "catch-up" premium amortization cost due to changes in our constant prepayment rate forecasts, the net interest margin between our assets and our cost of funds decreased to 1.41% during the third quarter of 2017, from 1.45% during the fourth quarter of 2016.
The funding landscape for Agency RMBS has remained favorable throughout the year in terms of relative interest rate levels and funding capacity. Our aggregate cost-of-funds, which includes the implied funding cost on our TBA position and the cost on our interest rate swaps, increased 31 basis points to 1.46% as of September 30, 2017, from 1.15% as of December 31, 2016. The average rate on our repurchase agreements increased 38 basis points to 1.36% as of September 30, 2017, from 0.98% as of December 31, 2016, while implied funding costs in the TBA dollar roll market remained favorable at 15 to 25 basis points below comparable


repo rates. Favorable implied funding levels and stable prepayment expectations led us to maintain a sizable TBA position throughout much of the period. Our cost of funds also benefited from a 39 basis point increase in the average receive rate on our pay-fixed receive-variable interest rate swaps over the first three quarters of the year, which was partly offset by higher costs associated with an increase in our swap portfolio in conjunction with our larger asset balance and an increase in the average maturity of our swap portfolio to 4.5 years as of September 30, 2017, from 3.9 years as of December 31, 2016. In addition, we achieved a greater diversity of funding and benefited from more favorable terms than traditional levels by shifting a larger portion our repo funding and TBA clearing through our captive broker-dealer subsidiary, Bethesda Securities, LLC, or "BES”. As of September 30, 2017, our repo funding transacted through BES totaled 30%, up significantly from 12% as of December 31, 2016.
As of September 30, 2017, our "at risk" leverage was 8.0x our tangible equity, up from 7.7x as of December 31, 2016. Additional Agency RMBS spread widening and ongoing favorable funding dynamics, could provide attractive investment opportunities and serve as a catalyst for us to further increase leverage.
As of September 30, 2017, our interest rate hedges equaled 92% of our funding liabilities and net TBA position, up slightly from 90% as of December 31, 2016. We believe operating at this level provides us a significant amount of protection against net asset value fluctuations due to interest rate changes. Our net "duration gap," which is a measure of the risk due to mismatches that can occur between the interest rate sensitivity of our assets and liabilities, inclusive of hedges, was 0.4 years as of September 30, 2017, down from 1.3 years as of December 31, 2016. The reduction in our net duration gap is a result of our larger hedge position and the overall decline in interest rates during the first three quarters of the year.and mortgage spreads, please refer to Item 3.

RESULTS OF OPERATIONS
Non-GAAP Financial Measures

In addition to the results presented in accordance with GAAP, our results of operations discussed below include certain non-GAAP financial information, including "adjusted net"economic interest income," "economic interest expense," and "net spread and dollar roll income" "net spread and dollar roll income, excluding 'catch-up' premium amortization," "estimated taxable income" available to common stockholders"1 and the related per common share measures and certain financial metrics derived from such non-GAAP information, suchinformation.
"Economic interest income" is measured as "cost of funds"interest income (GAAP measure), adjusted to (i) exclude retrospective "catch-up" adjustments to premium amortization cost associated with changes in projected CPR estimates and "net(ii) include TBA dollar roll implied interest rate spread."

"Adjusted netincome. "Economic interest expense" is measured as interest expense (GAAP measure) adjusted to include TBA dollar roll implied interest expense/benefit and interest rate swap periodic costs. "Net spread and dollar roll income" is measured as (i) net interest income (GAAP measure) adjusted to include interest rate swap periodic costs, TBA dollar roll income, management fee income and dividends on REIT equity securities (referred to as "adjusted net interest and dollar roll income") less (ii) total operating expenses (GAAP measure) adjusted to exclude non-recurring transaction costs (referred to as "adjusted operating expenses").cost/income. "Net spread and dollar roll income excluding 'catch-up' premium amortization," further excludesavailable to common stockholders" is measured as comprehensive income (loss) available (attributable) to common stockholders (GAAP measure) adjusted to: (i) exclude gains/losses on investment securities recognized through net income and other comprehensive income and gains/losses on derivative instruments and other securities (GAAP measures); (ii) exclude retrospective "catch-up" adjustments to premium amortization cost or benefit due toassociated with changes in projected CPR estimates.estimates; and (iii) include interest rate swap periodic income/cost, TBA dollar roll income and other interest income/expense. As defined "Net

31


spread and dollar roll income available to common stockholders" includes (i) the components of "economic interest income" and "economic interest expense", plus (ii) other interest income/expense, and less (iii) total operating expenses and dividends on preferred stock (GAAP measures).
By providing such measures, in addition to the related GAAP measures, we believe we give greater transparency into the information used by our management in its financial and operational decision-making. We also believe it is important for users of our financial information to consider information related to our current financial performance without the effects of certain measures and one-time events that are not necessarily indicative of our current investment portfolio performance and operations.

Specifically, in the case of "adjusted net interest"net spread and dollar roll income available to common stockholders" and components of such measure, "economic interest income" and "economic interest expense," we believe the inclusion of TBA dollar roll income is meaningful as TBAs, which are accounted for under GAAP as derivative instruments with gains and losses recognized in other gain (loss) in our consolidated statement of comprehensive income, are economically equivalent to holding and financing generic Agency RMBS using short-term repurchase agreements. Similarly, we believe that the inclusion of periodic interest rate swap settlements in such measure and in "adjusted net interest expense" is meaningful as interest rate swaps are the primary instrument we use to economically hedge against fluctuations in our borrowing costs and it is more indicative of our total cost of funds than interest expense alone. In the case of "net spread and dollar roll income, excluding 'catch-up' premium amortization,"Additionally, we believe the exclusion of "catch-up" adjustments to premium amortization cost or benefitadjustments is meaningful as it excludes the cumulative effect from prior reporting periods due to current changes in future prepayment expectations and, therefore, exclusion of such cost or benefitadjustments is more indicative of the current earnings potential of our investment portfolio. We also believe the exclusion of issuance costs of redeemed preferred stock reported as a reduction to net income available to common stockholders under GAAP and transactions costs associated with our acquisition of AMM reported in general, administrative and other expense under GAAP is meaningful as they represent non-recurring transaction costs and are not representative of our ongoing operating costs. In the case of estimated taxable income, we believe it is meaningful information because it directly relates to the amount of dividends we are required to distribute in order to maintain our REIT qualification status.

However, because such measures are incomplete measures of our financial performance and involve differences from results computed in accordance with GAAP, they should be considered as supplementary to, and not as a substitute for, results computed in accordance with GAAP. In addition, because not all companies use identical calculations, our presentation of such non-GAAP measures may not be comparable to other similarly-titledsimilarly titled measures of other companies. Furthermore, estimated taxable

Leverage
Our primary measure of leverage is our tangible net book value "at risk" leverage ratio. Tangible net book value "at risk" leverageratio, which is measured as the sum of our mortgage borrowings (consisting of repurchase agreements and other debt used to fund our investment securities ("Agency repo"), debt of consolidated VIEs and FHLB advances), net TBA and forward settling securities position (at cost) (together referred to as "mortgage borrowings") and our net receivable /payablereceivable/payable for unsettled investment securities, divided by the sum of our total stockholders' equity adjusted to exclude goodwill and other intangible assets related to our acquisition of AMM on July 1, 2016.goodwill.
We include our net TBA position in our measure of leverage because a forward contract to acquire Agency RMBS in the TBA market carries similar risks to Agency RMBS purchased in the cash market and funded with on-balance sheet liabilities. Similarly, a TBA contract for the forward sale of Agency securities has substantially the same effect as selling the underlying Agency RMBS and reducing our on-balance sheet funding commitments. (Refer to Liquidity and Capital Resources in this Form 10-Q for further discussion of TBA securities and dollar roll transactions). Repurchase agreements used to fund short-term investments in U.S.


Treasury securities ("U.S. Treasury repo") are excluded from our measure of leverage due to the temporary and highly liquid nature of these investments. The following table presents a summary of our leverage ratios for the periods listed (dollars in millions):

Our average mortgage borrowings, inclusive of TBAs, decreased 5% for the three months ended March 31, 2024, consistent with the decline in our asset balance and lower operating leverage. The average interest rate on our mortgage borrowings, excluding the impact interest rate swap period income, increased 92 basis points for the three months ended March 31, 2024 due to higher short-term interest rates.
Interest rate swap periodic income increased for the current year periods largelythree months ended March 31, 2024 due to increases in the federal funds rate, which werehigher receive rates on our pay-fixed swaps, partly offset by the benefit of shifting a larger portion of our total Agency repo funding through our captive broker-dealer subsidiary. The size of our total average borrowings outstanding decreased compared to the prior year periods due to the relative shift from Agency RMBS to TBA holdings, which was partly offset by a larger asset base as a function of new equity issuances during 2017 and modestly higher leverage.pay rates and a smaller swap balance. The decrease in our periodic swap cost was primarily due to an increase in the floating rate received on our pay-fixed receive-floating interest rate swaps. The size of our interest rate swap portfolio increased relative to our mortgage borrowings as a function of our larger TBA dollar roll position.

Net spread and dollar roll income, excluding "catch-up" premium amortization adjustments, for the three months ended September 30, 2017 was $0.62 per common share, or a decline of $0.02 per common share from the prior year period. The decline was largely due to higher funding costs and a modest compression of our net interest rate spread and dollar roll margin (i.e. the difference between the average yield on our assets and our average cost of funds inclusive of TBAs), excluding "catch-up" premium amortization adjustments.
Net spread and dollar roll income, excluding "catch-up" premium amortization adjustments, for the nine months ended September 30, 2017 was $1.94 per common share, compared to $1.72 per common share for the prior year period. The increase relative to the prior year period was largely due to the combination of lower operating costs as a function of our management internalization on July 1, 2016 and a higher relative net interest rate spread and dollar roll margin during much of the current year period.
Our average net interest rate spread and dollar roll margin, excluding "catch-up" premium amortization cost, was 1.41% and 1.50% for the three and nine months ended September 30, 2017, respectively, compared to 1.47% and 1.39%, respectively, for the prior year period. Including "catch-up" premium amortization adjustments, our net interest rate spread and dollar roll margin was 1.34% and 1.43% for the three and nine months ended September 30, 2017, respectively, compared to 1.42% and 1.18%, respectively, for the prior year period.

Operating Expenses
Prior to our acquisition of AMM and related management internalization on July 1, 2016, we paid our Manager a management fee payable monthly in arrears in an amount equal to one-twelfth of 1.25% of our month-end stockholders' equity, as defined in our management agreement. Following our management internalization, we no longer incur a management fee, but we incur expenses associated with an internally managed organization, including compensation expense previously borne by our Manager. For the three and nine months ended September 30, 2017, we incurred compensation and benefits expense of $10 million and $30 million, respectively. For the nine months ended September 30, 2016, prior to our internalization, we incurred management fees of $52 million and, subsequent to our internalization, compensation and benefits expense of $9 million.


For the three and nine months ended September 30, 2017, we incurred other operating expenses of $7 million and $20 million, respectively, compared to $6 million and $27 million, respectively, for the prior year period. Excluding non-recurring acquisition costs, we incurred other operating expenses of $6 million and $18 million, respectively, for the prior year period. Other operating expenses primarily consist of prime broker fees; clearing, settlement and regulatory fees incurred by BES; information technology costs; accounting, legal and Board of Director fees; amortization of intangible assets associated with our acquisition of AMM; and other general overhead expenses.
Our total annualized operating expense as a percentage of our average stockholders' equity was 0.84% and 0.87% for the three and nine months ended September 30, 2017, compared to 0.76% and 1.51%, respectively, for the prior year period. Excluding non-recurring acquisition costs, our total operating expense as a percentage of our stockholders' equity was 1.35% for the prior year nine month period.
Estimated Taxable Income
For the three months ended September 30, 2017 and 2016, we had estimated taxable income available to common stockholders of $42 million and $63 million (or $0.12 and $0.19 per common share), respectively. For the nine months ended September 30, 2017 and 2016, we had estimated taxable income available to common stockholders of $118 million and $210 million (or $0.34 and $0.63 per common share), respectively. Income as determined under GAAP differs from income as determined under tax rules because of both temporary and permanent differences in income and expense recognition. The primary differences are (i) unrealized gains and losses on derivative instruments and other securities marked-to-market in current income for GAAP purposes, but excluded from taxable income until realized or settled, (ii) timing differences, both temporary and potentially permanent, in the recognition of certain realized gains and losses and (iii) temporary differences related to the amortization of premiums and discounts on investments. Furthermore, our estimated taxable income is subject to potential adjustments up to the time of filing our appropriate tax returns, which occurs after the end of our fiscal year. The following is a reconciliation of our GAAP net income to our estimated taxable income for the three and nine months ended September 30, 2017 and 2016 (dollars in millions, except per share amounts):

Other Comprehensive Income (Loss)
Other comprehensive income (loss) primarily consists of unrealized gains and (losses) recognized due to the impact of fluctuations in long-term interest rates on the market value of our Agency RMBS designated as "available-for-sale" securities, net of reversals of prior period unrealized amounts upon realization. For the three and nine months ended September 30, 2017, we had other comprehensive income (loss) of $90 million and $257 million, respectively, compared to $(90) million and $1.1 billion for the three and nine months ended September 30, 2016, respectively.



LIQUIDITY AND CAPITAL RESOURCES
Our business is dependent on our ability to maintain adequate levels of liquidity and capital resources to fund day-to-day operations, fulfill collateral requirements under our funding and derivative agreements, and to satisfy our dividend distribution requirement of at least 90% of our taxable income to maintain our qualification as a REIT. Our primary sources of fundsliquidity are unencumbered cash and securities, borrowings available under master repurchase agreements, asset sales,TBA dollar roll financing and monthly receipts of monthly principal and interest payments onpayments. We may also conduct asset sales, change our investment portfolioasset or funding mix, issue equity or undertake other capital enhancing actions to maintain adequate levels of liquidity and equity offerings. We also enter into TBA contractscapital resources. There are various risks and uncertainties that can impact our liquidity, such as a means of acquiring or disposing of Agency securities and utilize TBA dollar roll transactions to finance Agency RMBS purchases.

Leverage and Financing Sources
Our leverage will vary depending on market conditions and our assessment of relative risks and returns, but we generally expect our leverage to be between six and twelve times the acquisition of additional investments, repayments on borrowings, maintenance of any margin requirements and the payment of cash dividends as required for our continued qualification as a REIT. We currently expect to distribute 100%amount of our taxable income so that we are not subject to U.S. federal and state corporate income taxes. Our REIT distribution requirement of at least 90% of our taxable income limits our ability to retain earnings and thereby replenish or increase capital from operations.

Our tangible net book value "at risk" leverage ratio was 7.1x and other intangible assets.
Repurchase Agreements
As part of our investment strategy, we borrow against our investment portfolio pursuant to master repurchase agreements. We expect that the majority of our borrowings under such master repurchase agreements will have maturities ranging up to one year, but we may have longer-term borrowings ranging up to five years or longer. Borrowings under our master repurchase agreements with maturities greater than 90 days typically have floating rates of interest based on LIBOR plus or minus a fixed spread.
As of September 30, 2017, we had $45.5 billion of repurchase agreements outstanding used to fund acquisitions of investment securities with a weighted average cost of funds of 1.36% and a weighted average remaining days-to-maturity of 129 days, compared $37.7 billion, 0.98% and 187 days, respectively,7.0x as of March 31, 2024 and December 31, 2016.
To limit our counterparty exposure, we diversify our funding across multiple counterparties and by counterparty region. As of September 30, 2017, we had master repurchase agreements with 41 financial institutions located throughout North America, Europe and Asia, including counterparties accessed through our wholly-owned captive broker-dealer subsidiary, Bethesda Securities. Bethesda Securities has direct access to bilateral and triparty funding, including the General Collateral Finance Repo service offered by the Fixed Income Clearing Corporation, or "FICC," which provides us greater depth and diversity of funding at favorable terms relative to traditional bilateral repurchase agreement funding. As of September 30, 2017, $13.8 billion of our repurchase agreement funding was accessed through Bethesda Securities.

2.As of March 31, 2024 and December 31, 2023, 42% and 43%, respectively, of our total repurchase agreements, including 43% and 45% or our investment securities repurchase agreements, respectively, were funded through the Fixed Income Clearing Corporation's GCF Repo service.
Our primary financing sources are collateralized borrowings structured as repurchase agreements. We enter into repurchase agreements, or "repo," through bi-lateral arrangements with financial institutions and independent dealers. We also enter into third-party repurchase agreements through our wholly-owned registered broker-dealer subsidiary, Bethesda Securities, LLC, such as tri-party repo offered through the FICC's GCF Repo service. We manage our repurchase agreement funding position through a variety of methods, including diversification of counterparties, maintaining a suitable maturity profile and utilization of interest rate hedging strategies. We also use TBA dollar roll transactions as a means of synthetically financing Agency RMBS.
The terms and conditions of our repurchase agreements are determined on a transaction-by-transaction basis when each such borrowing is initiated or renewed and, in the case of GCF Repo, by the prevailing margin requirements calculated by the FICC, which acts as the central counterparty. The amount borrowed is generally equal to the fair value of the securities pledged, as determined by the lending counterparty, less an assessed discount, referred to as a "haircut," that reflects the underlying risk of the specific collateral and protects the counterparty against a change in its value. Interest rates are generally fixed based on prevailing rates corresponding to the term of the borrowing. None of our repo counterparties are obligated to renew or otherwise enter into new borrowings at the conclusion of our existing borrowings.
The use of TBA dollar roll transactions increases our funding diversification, expands our available pool of assets, and increases our overall liquidity position, as TBA contracts typically have lower implied haircuts relative to Agency RMBS pools funded with repo financing. TBA dollar roll transactions may also have a lower implied cost of funds than comparable repo funded transactions (referred to as "dollar roll specialness") offering incremental return potential. However, if it were to become uneconomical to roll our TBA contracts into future months it may be necessary to take physical delivery of the underlying securities and fund those assets with cash or other financing sources, which could reduce our liquidity position.

Collateral Requirements and Unencumbered Assets
Amounts available to be borrowed under our repurchase agreements are dependent upon lender collateralprevailing interest rates, the lender’s "haircut" requirements and the lender's determinationcollateral value. Each of the fair value of the securities pledged as collateral, which fluctuatesthese elements may fluctuate with changes in interest rates, credit quality and liquidity conditions within the investment banking, mortgage finance and real estate industries. In addition, our counterparties apply a "haircut" to our pledged collateral, which means our collateral is valued at slightly less than market value. This haircut reflects the underlying risk of the specific collateral and protects our counterparty against a change in its value, but conversely subjects us to counterparty credit risk and limits the amount we can borrow against our investment securities. Our master repurchase agreements do not specify the haircut; rather haircuts are determined on an individual repurchase transaction basis. Throughout the nine months ended September 30, 2017, haircuts on our pledged collateral remained stable and, as of September 30, 2017, our weighted average haircut was approximately 4.5% of the value of our collateral, inclusive of collateral funded through Bethesda Securities. As of September 30, 2017, our maximum amount at risk (or the amount or our repurchase liabilities in excess of the value of collateral pledged) with any counterparty related to our repurchase agreements was less than 5% of our tangible stockholders' equity, and our top five repo counterparties represented less than 12% of our tangible stockholders' equity.
We may be required to pledge additional assets to our counterparties in the event the estimated fair value of the existing collateral pledged under our agreements declines and our counterparties demand additional collateral (a "margin call"), which may take the form of additional securities or cash. Specifically, margin calls would result from a decline in the fair value of our investment securities securing our repurchase agreements as well as due to prepayments on the mortgages securing such securities. Similarly, if the estimated fair value of our investment securities increases due to changes in interest rates or other factors, counterparties may release collateral back to us. Our repurchase agreements generally provide that the valuations of securities securing our repurchase agreements are to be obtained from a generally recognized source agreed to by the parties. In certain circumstances, however, our lenders have the sole discretion to determine the value of pledged collateral. In such instances, our lenders are required to act in good faith in making determinations of value. Our repurchase agreements generally provide that in the event of a margin call, we must provide additional securities or cash on the same business day that a margin call is made if the lender provides us notice prior to the margin notice deadline on such day.
As of September 30, 2017, we had met all of our margin requirements and we had unrestricted cash and cash equivalents of $1.1 billion and unpledged securities of approximately $3.6 billion, including securities pledged to us and unpledged interests in our consolidated VIEs, available to meet margin calls on our repurchase agreements and other funding liabilities, derivative instruments and for other corporate purposes.
Although we believe we will have adequate sources of liquidity available to us through repurchase agreement financing to execute our business strategy, there can be no assurances that repurchase agreement financing will be available to us upon the maturity of our current repurchase agreements to allow us to renew or replace our repurchase agreement financing on favorable terms or at all. If our repurchase agreement lenders default on their obligations to resell the underlying collateral back to us at the end of the term, we could incur a loss equal to the difference between the value of the collateral and the cash we originally received.
financial markets. To help manage the adverse impact of interest rate changes on the value of our investment portfolio as well as our cash flows,borrowings, we utilize an interest rate risk management strategy under which weinvolving the use of derivative financial instruments. In particular, we attempt to mitigate the risk of the cost of our variable rateshort-term funding liabilities increasing at a faster rate than the earnings of our long-term fixed rate assets during a period of rising interest rates.
The primary derivative instruments that we usecollateral requirements, or haircut levels, under our repo agreements are interest rate swaps, interest rate

As of March 31, 2024, we had met all our margin requirements.
The value of Agency RMBS collateral is impacted by market factors and is reduced by monthly principal pay-downs on the underlying mortgage pools. Fannie Mae and Freddie Mac publish monthly security pay-down factors for their mortgage pools on the fifth day after month-end, but do not remit payment to security holders until generally the 25th day after month-end. Bi-lateral repo counterparties assess margin to account for the reduction in value of Agency collateral when factors are released. The FICC assesses margin on the last day of each month, prior to the factor release date, based on its internally projected pay-down rates (referred to as the "blackout period exposure adjustment" or next business day."blackout margin"). On the factor release date, the blackout margin is released and collateralization requirements are adjusted to actual factor data. Due to the timing difference between associated margin calls and our receipt of principal pay-downs, our liquidity is temporarily reduced each month for principal repayments. We minimize counterparty creditattempt to manage the liquidity risk associated with our derivative instruments by limiting our counterparties to central clearing exchanges and major financial institutions with acceptable credit ratings andprincipal pay-downs by monitoring positions with individual counterparties. Excluding centrally cleared derivative instruments, asconditions impacting prepayment rates and through asset selection. As of September 30, 2017, our amount at risk with any counterparty related to our interest rate swap and swaption agreements was less than 1%March 31, 2024, approximately 13% of our stockholders' equity. In the case of centrally cleared derivative instruments, we could be exposed to credit risk if the central clearing agency or a clearing member defaults on its respective obligation to perform under the contract. However, we believe that the risk is minimal due to the exchanges' initial and daily mark to market margin requirements and clearinghouse guarantee funds and other resources that are available in the event of a clearing member default.
TBA Dollar Roll Transactions
TBA dollar roll transactions represent a form of off-balance sheet financing accounted for as derivative instruments and we may use them as a means of leveraging (or deleveraging) our investment portfolio through the useconsisted of long (or short) TBA contracts (see Notes 3 and 6securities, which are not subject to monthly principal pay-downs. The remainder of our portfolio primarily consisted of Agency RMBS, which had an average one-year CPR forecast of 8%.

If we were required to take physical delivery to settle a long TBA contract, we would have to fund our total purchase commitment with cash or other financing sources and our liquidity position could be negatively impacted. As of September 30, 2017, we had a net long TBA position with a total market value and a total cost basis of $19.4 billion and a net carrying value of $(24) million recognized in derivative assets/(liabilities), at fair value, on our Consolidated Balance Sheets in this Form 10-Q.
Our TBA dollar roll contractsfactors. We are also subject to daily variation margin requirements based on changes in the value of the derivative instrument and/or collateral pledged. Daily variation margin requirements also entitle us to receive collateral if the value of amounts owed to us under the derivative agreement exceeds the minimum margin requirement. The collateral requirements under our TBA contracts are governed by the Mortgage-Backed Securities Division ("MBSD") of the FICCFICC. Collateral levels for interest rate derivative agreements are typically governed by the central clearing exchange and by our prime brokerage agreements,the associated futures commission merchants ("FCMs"), which may establish margin levels in excess of the MBSD. Such provisions require that we establish an initial margin based on the notional value of the TBA contract, which isclearing exchange. Collateral levels for interest rate derivative agreements not subject to increase ifcentral clearing are established by the estimated fair valuecounterparty financial institution.
Haircut levels and minimum margin requirements imposed by our counterparties reduce the amount of our TBA contract orunencumbered assets and limit the estimated fair valueamount we can borrow against our investment securities. During the three months ended March 31, 2024, haircuts on our repo funding arrangements remained stable. As of March 31, 2024, the weighted average haircut on our pledged collateral declines. The MBSD has the sole discretion to determinerepurchase agreements was approximately 3.0% of the value of our TBA contractscollateral, compared to 3.1% as of December 31, 2023.
To mitigate the risk of margins calls, we seek to maintain excess liquidity by holding unencumbered liquid assets that can be used to satisfy collateral requirements, collateralize additional borrowings or sold for cash. As of March 31, 2024, our unencumbered assets totaled approximately $5.4 billion, or 68% of tangible equity, consisting of $5.4 billion of unencumbered cash and Agency RMBS and $0.1 billion of unencumbered credit assets. This compares to $5.2 billion of unencumbered assets, or 67% of tangible equity, as of December 31, 2023, consisting of $5.1 billion of unencumbered cash and Agency RMBS and $0.1 billion of unencumbered credit assets.
Counterparty Risk
Collateral requirements imposed by counterparties subject us to the risk that the counterparty does not return pledged assets to us as and when required. We attempt to manage this risk by monitoring our collateral positions and limiting our counterparties to registered clearinghouses and major financial institutions with acceptable credit ratings. We also diversify our funding across multiple counterparties and by region.

Regulatory capital in excess of the minimum required by the Rule is held to meet levels required by clearing organizations, the clearing bank and other repo counterparties.our stockholders' equity.
Asset Sales
Agency RMBS securities are among the most liquid fixed income securities, and TBA Eligible Securities
We maintain a portfolio of highly liquid mortgage-backed securities. We may sell our Agency securities through the TBA market by delivering themis the second most liquid market (after the U.S. Treasury market). Although market conditions fluctuate, the vitality of these markets enables us to sell assets under most conditions to generate liquidity through direct sales or delivery into TBA contracts, subject to "good delivery" provisions promulgated by the Securities Industry and Financial Markets Association ("SIFMA"). Under certain market conditions, however, we may be unable to realize the full carrying value of our securities. We attempt to manage this risk by maintaining at least a minimum level of securities that trade at or near TBA values that in our estimation enhances our portfolio liquidity across a wide range of market conditions. Please refer to Trends and Recent Market Impacts of this Management Discussion and Analysis for further information regarding Agency RMBS and TBA market conditions.
Capital Markets
The equity capital markets serve as a source of capital to grow our business and to meet potential liquidity needs of our business. The availability of equity capital is dependent on market conditions and investor demand for our common and preferred stock. We will typically not issue common stock at times when we believe the capital raised will not be accretive to our tangible net book value or earnings, and we will typically not issue preferred equity when its cost exceeds acceptable hurdle rates of return on our equity. We may alternatively sell Agency securities that have more unique attributes on a specified basis when such securities trade at a premium over generic TBA securities or if the securities are not otherwise eligible for TBA delivery. Since the TBA market is the second most liquid market (after the U.S. Treasury market), maintaining a significant


level of Agency securities eligible for TBA delivery enhances our liquidity profile and provides price support for our TBA eligible securities at or above generic TBA prices. As of September 30, 2017, approximately 90% of our fixed rate Agency RMBS portfolio was eligible for TBA delivery.
Equity Capital
In September 2017, we completed a public offering in which 28.2 million shares of our common stock were sold to the underwriters for proceeds of $577 million, or $20.47 per common share, net of estimated offering costs. In May 2017, we completed a public offering in which 24.5 million shares of our common stock were sold to the underwriters for proceeds of $503 million, or $20.51 per common share, net of offering costs. We are also authorized by our Board of Directors to publicly offer and sell shares of our common stock in privately negotiated and/or at-the-market transactions from time-to-time up to an aggregate amount of $750 million of shares of our common stock, subject to U.S. Federal securities laws. During the three and nine months ended September 30, 2017, we sold 7.6 million shares of our common stock under the sales agreements for proceeds of $159 million, or $20.96 per common share, net of estimated offering costs. As of September 30, 2017, $589 million of shares of our common stock remain available for issuance under this program.
In August 2017, we issued 13,000 shares of 7.00% Series C Fixed-to-Floating Rate Cumulative Redeemable Preferred Stock in a public offering of 13.0 million Series C depositary shares at a price of $25 per depositary share for net proceeds of $315 million, after deducting estimated offering expenses. In September 2017, we redeemed all of our issued and outstanding shares of 8.000% Series A Cumulative Redeemable Preferred Stock for $173 million (or $25 per share liquidation preference), plus accrued and unpaid dividends.
To the extent we raise additional equity capital we may use cash proceeds from such transactions to purchase additional investment securities, to make scheduled payments of principal and interest on our funding liabilities and for other general corporate purposes.  There can be no assurance, however, that we will be ableunable to raise additional equity capital at any particular timesuitable times or on any particularfavorable terms. Furthermore, when the trading price of our common stock is significantly less than our then-current estimate of our current tangible net assetbook value per common share, among other conditions, we may repurchase shares of our common stock subjectpursuant to the provisions of our stock repurchase program (seeplan authorized by our Board of Directors, which has $1 billion in remaining capacity and expires on December 31, 2024.

Changes in the general levelborrowings are generally based on prevailing market interest rates. During a period of rising interest rates, our borrowing costs generally will increase while the yields earned on our existing portfolio of leveraged fixed-rate assets will largely remain static. This can affectresult in a decline in our net interest income, which is the difference between the interest income earned on interest-earning assets and the interest expense incurred in connection with our interest-bearing liabilities, by affecting the spread between our interest-earning assets and interest-bearing liabilities.spread. Changes in the level of interest rates can also affect the rate of mortgage prepayments of our securities and the value of the mortgage securities that constitute our investment portfolio, which affectsassets.

The principal instruments that we use to hedge our interest rate risk are interest rate swaps, swaptions, U.S. Treasury securities and U.S. Treasury futures contracts. WeOur hedging techniques are highly complex and are partly based on assumed levels of prepayments of our assets. If prepayments are slower or faster than assumed, the maturity of our investments will also use forward contractsdiffer from our expectations, which could reduce the effectiveness of our hedging strategies and may cause losses on such transactions and adversely affect our cash flow.
The severity of potential declines in our tangible net book value due to fluctuations in interest rates would depend on our asset, liability, and hedge composition at the Agency RMBS TBA market to invest in and finance Agency securitiestime, as well as to periodically reduce our exposure to Agency RMBS.

rate change. Primary measures of an instrument's price sensitivity to interest rate fluctuations are its duration and convexity. Duration measures the estimated percentage change in market value of our mortgage assets or our hedge portfolioan instrument that would be caused by a parallel change in short and long-term interest rates. The duration of our investment portfolioassets will vary with changes within interest rates and tends to increase when interest rates rise and decrease when interest rates fall. This "negative convexity" generally increases the interest rate exposure of our investment portfolio in excess of what is measured by duration alone.
We estimate the duration and convexity of our portfolioassets using both a third-party risk management system and market data. We review the duration estimates from the third-party modelfor reasonableness, giving consideration to any unique characteristics of our securities, market conditions and other factors likely to impact these estimates, and based on our judgement we may make adjustments based onto the third-party estimates.

All changes in income and valuevalues in the table below are measured as percentage changes from the base interest rate scenario. The base interest rate scenario assumes interest rates and prepayment projections as of September 30, 2017March 31, 2024 and December 31, 2016. We apply a floor of 0% for the down rate scenarios on our interest bearing liabilities and the variable leg of our interest rate swaps, such that any hypothetical interest rate decrease would have a limited positive impact on our funding costs beyond a certain level.2023.

Prepayment Risk and Extension Risk
Because residential borrowers have the option to prepay their mortgage loans at par at any time, we facePrepayment risk is the risk that weour assets will experiencebe repaid at a return of principal on our investments faster rate than anticipated. VariousInterest rates and numerous other factors affect the rate at which mortgageof prepayments, occur, including changes in the level of and directional trends insuch as housing prices, interest rates, general economic conditions, loan age, size and size, loan-to-value ratio, the locationratios, and GSE buyouts of the property and social and demographic conditions. Additionally, changes to GSE underwriting practices or other governmental programs could also significantly impact prepayment rates or expectations. Also, the pace at which thedelinquent loans underlying our securities become seriously delinquent or are modified and the timing of GSE repurchases of such loans from our securities can materially impactsecurities. Generally, declining mortgage rates increase the rate of prepayments. Generally, prepayments, on residential mortgage-backed securities increase during periods of falling mortgage interestwhile rising rates and decrease during periods of rising mortgage interest rates. However, thishave the opposite effect.
If our assets prepay at a faster rate than anticipated, we may not always be the case.
We mayunable to reinvest principalthe repayments at a yield that isacceptable yields. If the proceeds are reinvested at lower or higheryields than the yield on the repaid investment, thus affectingour existing assets, our net interest income by altering the average yield on our assets.would be negatively impacted. We also amortize or accrete premiums and discounts associated withwe pay or receive at purchase relative to the purchasestated principal of mortgage securitiesour assets into interest income over thetheir projected lives of the securities, including contractual payments and estimated prepayments using the effective interest method. Our policy for estimating prepayment speeds for calculating the effective yield is to evaluate published prepayment data for similar securities, market consensus and current market conditions. If the actual and estimated future prepayment experiencedexperience differs from our estimateprior estimates, we are required to record an adjustment to interest income for the impact of prepayments,the cumulative difference in the effective yield.
Extension risk is the risk that our assets will be repaid at a slower rate than anticipated and generally increases when interest rates rise. In a rising or higher interest rate environment, we willmay be required to make an adjustmentfinance our investments at potentially higher costs without the ability to reinvest principal into higher yielding securities as a result of borrowers prepaying their mortgages at a slower pace than originally anticipated, adversely impacting our net interest spread, and thus our net interest income.
As of March 31, 2024 and December 31, 2023, our investment securities (excluding TBAs) had a weighted average projected CPR of 10.4% and 11.4%, respectively, and a weighted average yield of 4.52% and 4.41%, respectively. The table below presents estimated weighted average projected CPRs and yields for our investment securities should interest rates go up or down instantaneously by 25, 50 and 75 basis points. Estimated yields exclude the impact of retroactive "catch-up" premium amortization or accretionadjustments for prior periods due to changes in the projected CPR assumption.

Spread Risk
WhenSpread risk is the risk that the market spread between the yield on our investment securitiesassets and the yield on benchmark interest rates widens,linked to our net book value could decline if the valueinterest rate hedges, such as U.S. Treasury rates and interest rate swap rates, may vary. As a levered investor in mortgage-backed securities, spread risk is an inherent component of our investment securities fall by more than the offsetting fair value increases on ourstrategy. Therefore, although we use hedging instruments tied to the underlying benchmark interest rates. We refer to this as "spread risk" or "basis risk." The spread risk associated with our mortgage assets and the resulting fluctuations in fair value of these securities can occur independent of changes in benchmark interest rates and may relate to other factors impacting the mortgage and fixed income markets, such as actual or


anticipated monetary policy actions by the Federal Reserve, market liquidity, or changes in required rates of return on different assets. Consequently, while we use interest rate swaps and other supplemental hedges to attempt to protect against moves in interest rates, such instruments typically willour hedges are generally not designed to protect against spread risk, and our tangible net book value against spread risk.could decline if spreads widen.
Fluctuations in mortgage spreads can occur due to a variety of factors, including changes in interest rates, prepayment expectations, actual or anticipated monetary policy actions by the U.S. and foreign central banks, liquidity conditions, required rates of returns on different assets and other market supply and demand factors. The table below quantifies the estimated changes in the fair value of our investment portfolio (including derivativesassets, net of hedges, and other securities used for hedging purposes) and in our tangible net assetbook value per common share as of September 30, 2017March 31, 2024 and December 31, 20162023 should spreads widen or tighten by 10, 25 and 2550 basis points. The estimated impact of changes in spreads is in addition to our interest rate shock sensitivity included in the interest rate shock table above.

Liquidity Risk
The primaryOur liquidity risk for usprincipally arises from financing long-term fixed rate assets with shorter-term variable rate borrowings. Future borrowings through repurchase agreementsare dependent upon the willingness of lenders to finance our investments, lender collateral

requirements and other short-term funding agreements.  the lenders’ determination of the fair value of the securities pledged as collateral, which fluctuates with changes in interest rates and liquidity conditions within the commercial banking and mortgage finance industries. 
As of September 30, 2017,March 31, 2024, we had unrestricted cashbelieve that we have sufficient liquidity and cash equivalents of $1.1 billion and unpledged securities of approximately $3.6 billion, including securities pledged to us and unpledged interests in our consolidated VIEs,capital resources available to meet margin calls onexecute our funding liabilitiesbusiness strategy (see Liquidity and derivative contracts andCapital Resources in this Form 10-Q for other corporate purposes.additional details). However, should the value of our collateral or the value of our derivative instruments suddenly decrease, or margin calls relatingrequirements increase, we may be required to our funding liabilities and derivative agreements could increase,post additional collateral for these arrangements, causing an adverse change in our liquidity position. Furthermore, there is no assurance that we will always be able to renew (or roll) our short-term funding liabilities. In addition, our counterparties have the option to increase our haircuts (margin requirements) on the assets we pledge against our funding liabilities, thereby reducing the amount that can be borrowed against an asset even if they agree to renew or roll suchour funding liabilities. Significantly higher haircuts can reduce our ability to leverage our portfolio or may even force us to sell assets, especially if correlated with asset price declines or faster prepayment rates on our assets.
In addition, we often utilize TBA dollar roll transactions as a means of investing in and financing Agency RMBS. Under certain economic conditions it may be uneconomical to roll our TBA dollar roll transactions prior to the settlement date and we could have to take physical delivery of the underlying securities and settle our obligations for cash, which could negatively impact our liquidity position, result in defaults or force us to sell assets under adverse conditions.
Extension Risk
The projected weighted-average life and estimated duration, or interest rate sensitivity, of our investments is based on our assumptions regarding the rate at which the borrowers will prepay the underlying mortgage loans. In general, we use interest rate


swaps and swaptions to help manage our funding cost on our investments in the event that interest rates rise.  These swaps (or swaptions) allow us to reduce our funding exposure on the notional amount of the swap for a specified period of time by establishing a fixed rate to pay in exchange for receiving a floating rate that generally tracks our financing costs under our funding liabilities.
However, if prepayment rates decrease in a rising interest rate environment, the average life or duration of our fixed rate assets generally extends. This could have a negative impact on our results from operations, as our interest rate swap maturities are fixed and will, therefore, cover a smaller percentage of our funding exposure on our mortgage assets to the extent that their average lives increase due to slower prepayments. This situation may also cause the market value of our fixed rate securities to decline by more than otherwise would be the case while most of our hedging instruments would not receive any incremental offsetting gains.  In extreme situations, we may be forced to sell assets to maintain adequate liquidity, which could cause us to incur realized losses.
Credit Risk
Our credit sensitive investments, such as CRT and non-Agency securities, expose us to the risk of nonpayment of principal, interest or other remuneration we are contractually entitled to. We are also exposed to credit risk relatedin the event our repurchase agreement counterparties default on their obligations to resell the underlying collateral back to us at the end of the repo term or in the event our CRT and non-Agency investments, certain derivative transactions, andcounterparties do not perform under the terms of our collateral held by funding and derivative counterparties. agreements.
We accept credit exposure related to our credit sensitive assets at levels we deem prudent as an integral partwithin the context of our overall investment and hedging strategy. We seekattempt to manage this risk through prudentcareful asset selection, pre-acquisition due diligence, post-acquisition performance monitoring, and the sale of assets where we have identifiedidentify negative credit trends and the use of various types of credit enhancements.trends. We may also use non-recourse financing, which limits our exposure tomanage credit losses to the specific securities subject to the non-recourse financing. Our overall management of credit exposure may also include the use ofrisk with credit default swaps or other financial derivatives that we believe are appropriate. Additionally, we may vary the percentage mix of our investmentsinterest rate and credit sensitive assets or our duration gap to adjust our credit exposure and/or improve the return profile of our assets, such as when we believe credit performance is inversely correlated with changes in interest rates, in an effort to actively adjust our credit exposure and to improve the risk/return profile of our investment portfolio.
rates. Our credit risk related to certain derivative and repurchase agreement transactions is largely mitigated through daily adjustments to collateral pledged based on changes in market value and we limitby limiting our counterparties to major financial institutions with acceptable credit ratings. There is no guarantee thatratings or to registered central clearinghouses and monitoring concentration levels with any one counterparty. We also continuously monitor and adjust the amount of collateral pledged based on changes in market value. However, our efforts to manage credit risk willmay be successfulunsuccessful and we could suffer losses if credit performance is worseas a result. Excluding central clearing exchanges, as of March 31, 2024, our maximum amount at risk with any counterparty related to our repurchase agreements and derivative agreements was less than our expectations or if economic conditions worsen.
