NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Unaudited Interim Consolidated Financial Statements

The unaudited interim consolidated financial statements of American Capital Mortgage Investment Corp. (referred to 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 our wholly-owned subsidiaries, American Capital Mortgage Investment TRS, LLC and American Capital Mortgage 2013, LLC and, in turn, its wholly-owned subsidiary Residential Credit Solutions, Inc. ("RCS"). 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 were incorporated in Maryland on March 15, 2011 and commenced operations on August 9, 2011 following the completion of our initial public offering ("IPO"). We are externally managed by American Capital MTGE Management, LLC (our "Manager"), an affiliate of American Capital, Ltd. ("American Capital"). Our common stock is traded on the NASDAQ Global Select Market under the symbol "MTGE."

We invest in, finance and manage a leveraged portfolio of mortgage-related investments, which we define to include agency residential mortgage-backed securities ("RMBS"), non-agency mortgage investments and other mortgage-related investments. Agency RMBS include residential mortgage pass-through certificates and collateralized mortgage obligations ("CMOs") structured from residential mortgage pass-through certificates for which the principal and interest payments are guaranteed by a government-sponsored enterprise ("GSE"), such as Federal National Mortgage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation ("Freddie Mac"), or by a U.S. Government agency, such as Government National Mortgage Association ("Ginnie Mae"). Non-agency mortgage investments include RMBS backed by residential mortgages that are not guaranteed by a GSE or U.S. Government agency. Non-agency mortgage investments may also include prime and non-prime residential mortgage loans. Other mortgage-related investments may include mortgage servicing rights ("MSR"), GSE credit risk transfer securities, commercial mortgage-backed securities ("CMBS"), commercial mortgage loans and mortgage-related derivatives.

Our objective is to provide attractive risk-adjusted returns to our stockholders over the long-term through a combination of dividends and net book value appreciation. In pursuing this objective, we rely on our Manager’s expertise to construct and manage a diversified mortgage investment portfolio by identifying asset classes that, when properly financed and hedged, are designed to produce attractive returns across a variety of market conditions and economic cycles, considering the risks associated with owning such investments.

We have elected 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 at least 90% of our taxable net 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 net income to the extent that we distribute all of our annual taxable net income to our stockholders. It is our intention to distribute 100% of our taxable net income, after application of available tax attributes, within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year.

On November 27, 2013, our wholly-owned subsidiary, American Capital Mortgage 2013, LLC acquired RCS, a fully-licensed mortgage servicer based in Fort Worth, Texas that has approvals from Fannie Mae, Freddie Mac, and Ginnie Mae to hold and manage MSR and residential mortgage loans. See Note 11 - Other Assets for additional information.

6

Note 3. Summary of Significant Accounting Policies

Fair Value of Financial Assets

We have elected the option to account for all of our financial assets, including all mortgage-related investments, at estimated fair value, with changes in fair value reflected in income during the period in which they occur. In management's view, this election more appropriately reflects the results of our operations for a particular reporting period, as financial asset fair value changes are presented in a manner consistent with the presentation and timing of the fair value changes of hedging instruments. See Note 9 - Fair Value Measurements.

Interest Income

Interest income is accrued based on the outstanding principal amount of the securities and their contractual terms. Premiums or discounts associated with the purchase of agency RMBS and non-agency RMBS 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.

We estimate long-term prepayment speeds using a third-party service and market data. The third-party service estimates prepayment speeds for our securities using models that incorporate the mortgage rates, age, size and loan-to-value ratios of the outstanding underlying loans, as well as current mortgage rates, forward yield curves, volatility and other factors. We review the prepayment speeds estimated by the third-party service and compare the results to market consensus prepayment speeds, if available. We also consider historical prepayment speeds and current market conditions to validate the reasonableness of the prepayment speeds estimated by the third-party service, and based on our Manager’s judgment, we may make adjustments to its estimates. Actual and anticipated prepayment experience is reviewed at least quarterly and effective yields are recalculated when differences arise between the previously estimated future prepayments and the amounts actually received plus currently anticipated future prepayments. If the actual and anticipated future prepayment experience differs from our prior estimate of prepayments, we are required to record an adjustment in the current period to the amortization or accretion of premiums and discounts for the cumulative difference in the effective yield through the reporting date.

At the time we purchase non-agency RMBS and loans 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 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 input and analysis received from external sources, internal models, and our judgment about interest rates, prepayment rates, the timing and amount of credit losses, 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, if any.

Mortgage Servicing Rights, at Fair Value

Our MSR represent the right to service mortgage loans for a servicing fee. MSR are reported at fair value on our consolidated balance sheets, with changes in fair value related to changes in valuation inputs and assumptions reported as unrealized loss on MSR on the consolidated statements of operations. Servicing fees, incentive fees and ancillary income are reported within servicing income on the consolidated statements of operations. The related servicing expenses and realization of cash flows related to underlying loan repayments, net of recoveries of contractual prepayment protection, are recorded in servicing expenses on the consolidated statements of operations. See Note 10 - Mortgage Servicing Rights for further discussion on MSR.

The accounting model used to evaluate whether a transfer of MSR qualifies as a sale is based on a risks and rewards approach, as MSR are not financial assets. In certain cases where we transfer the economics of MSR while retaining the actual servicing function, we retain the risk associated with servicing and, as a result, the transfer does not qualify for sale accounting. As such, we retain the MSR, together with an offsetting financing liability on our consolidated balance sheets. We have elected the option to account for MSR financing liabilities at estimated fair value, with changes in fair value reflected in income during the period in which they occur. See Note 12 - Accounts Payable and Other Accrued Liabilities for the presentations of our mortgage servicing liability.

We may be obligated to fund advances of principal and interest payments due to third party owners of the loans but not yet received from the individual borrowers. We may also be obligated to fund advances of real estate taxes and insurance,

7

protective advances to preserve the value of the underlying property, and expenses associated with remedial action in respect of defaulted loans. These servicing advances are reported within other assets on the consolidated balance sheets.

REIT Equity Securities, at Fair Value

REIT equity securities represent investments in the common stock of other publicly traded mortgage REITs that invest predominately in agency RMBS. We designate our investments in REIT equity securities as trading securities and report them at fair value on the accompanying consolidated balance sheets with changes in fair value recorded in unrealized gain (loss) on other derivatives and securities, net on the accompanying consolidated statements of operations. Dividend income from REIT equity securities is recorded in realized gain on other derivatives and securities, net.

Repurchase Agreements

We finance the acquisition of agency RMBS and certain non-agency RMBS for our investment portfolio through repurchase transactions under master repurchase agreements. We account for repurchase transactions as collateralized financing transactions which are carried at their contractual amounts, including accrued interest, as specified in the respective transaction agreements. The contractual amounts approximate fair value due to their short-term nature.

Reverse Repurchase Agreements and Obligation to Return Securities Borrowed under Reverse Repurchase Agreements

From time to time we borrow securities to cover short sales of U.S. Treasury securities through reverse repurchase transactions under our master repurchase agreements (see Derivatives below). We account for these as securities borrowing transactions and recognize an obligation to return the borrowed securities at fair value on the consolidated balance sheets based on the value of the underlying borrowed securities as of the reporting date. Our reverse repurchase agreements generally mature daily. The fair value of our reverse repurchase agreements is assumed to equal cost as the interest rates are reset daily.

Derivatives

We utilize a risk management strategy, under which we may use a variety of derivative instruments to hedge some of our exposure to market risks, including interest rate risk, prepayment risk, extension risk and credit risk. The objective of our risk management strategy is to reduce fluctuations in net book value over a range of market conditions. The principal instruments that we currently use are interest rate swaps and options to enter into interest rate swaps ("interest rate swaptions"). We also utilize forward contracts for the purchase or sale of agency RMBS, or to-be-announced forward ("TBA") contracts, and short sales of U.S. Treasury securities and U.S. Treasury futures contracts. We may also purchase or write put or call options on TBA securities and we may invest in other types of mortgage derivatives, such as synthetic total return swaps.

We also enter into TBA contracts as a means of investing in and financing agency RMBS (thereby increasing our "at

risk" leverage) or as a means of disposing of or reducing our exposure to agency RMBS (thereby reducing our "at risk" leverage). Pursuant to TBA contracts, we agree to purchase or sell, for future delivery, agency RMBS with certain principal and interest terms and certain types of collateral, but the particular agency RMBS to be delivered are not identified until shortly before the TBA settlement date. We may also choose, prior to settlement, to move the settlement of these securities out to a later date by entering into an offsetting short or long position (referred to as a "pair off"), net settling the paired off positions for cash, and simultaneously purchasing or selling a similar TBA contract for a later settlement date. This transaction is commonly referred to as a "dollar roll." The agency RMBS purchased or sold for a forward settlement date are typically priced at a discount to agency RMBS for settlement in the current month. This difference (or discount) is referred to as the "price drop." The price drop is the economic equivalent of net interest carry income on the underlying agency RMBS over the roll period (interest income less implied financing cost) and is commonly referred to as "dollar roll income (loss)." Consequently, forward purchases of agency RMBS and dollar roll transactions represent a form of off-balance sheet financing.

We recognize all derivative instruments as either assets or liabilities on the balance sheets, measured at fair value. As we have not designated any derivatives as hedging instruments, all changes in fair value are reported in earnings in our consolidated statements of operations in unrealized gain (loss) on other derivatives and securities, net during the period in which they occur. Derivatives in a gain position are reported as derivative assets at fair value and derivatives in a loss position are reported as derivative liabilities at fair value in our consolidated balance sheets. Cash receipts and payments related to 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.

Our derivative agreements generally contain provisions that allow for netting or setting off derivative assets and liabilities with each counterparty; however, we report related assets and liabilities on a gross basis in our consolidated balance sheets.

8

The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. We attempt to minimize this risk by limiting our counterparties to major financial institutions with acceptable credit ratings, monitoring positions with individual counterparties and adjusting posted collateral as required.

Interest rate swap agreements

We use interest rate swaps to hedge the variable cash flows associated with short-term borrowings made under our repurchase agreement facilities. 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") with terms up to 15 years. The floating rate we receive under our swap agreements has the effect of offsetting the repricing characteristics of our repurchase agreements and cash flows on such liabilities. Our swap agreements are privately negotiated in the over-the-counter ("OTC") market and may be centrally cleared through a registered commodities exchange ("centrally cleared swaps").

We estimate the fair value of our centrally cleared interest rate swaps using the daily settlement price determined by the respective exchange. Centrally cleared swaps are valued by the exchange using a pricing model that references the underlying rates, including the overnight index swap rate and LIBOR forward rate, to produce the daily settlement price. We estimate the fair value of our "non-centrally cleared" swaps using a combination of inputs from counterparty and third-party pricing models to estimate the net present value of the future cash flows using a forward yield curve in effect as of the end of the measurement period. We also incorporate any of our own and our counterparties’ unmitigated nonperformance risk in estimating the fair value of our interest rate swaps. In considering the effect of nonperformance risk, we consider the impact of netting and credit enhancements, such as collateral postings and guarantees, and have concluded that our own and our counterparty credit risk is not significant to the overall valuation of these agreements.

The payment of periodic settlements of net interest on interest rate swaps is reported in realized loss on periodic settlements of interest rate swaps, net in our consolidated statements of operations. Cash payments received or paid for the early termination of an interest rate swap agreement are recorded as realized gain on other derivatives and securities, net in our consolidated statements of operations. Changes in fair value of our interest rate swap agreements are reported in unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations.

Interest rate swaptions

We purchase interest rate swaptions to help mitigate the potential impact of larger increases or decreases in interest rates

on the performance of our investment portfolio. The interest rate swaptions provide us the option to enter into an interest rate swap agreement for a predetermined notional amount, stated term and pay or receive interest rates in the future. The premium paid for interest rate swaptions is reported as a derivative asset in our consolidated balance sheets. We estimate the fair value of interest rate swaptions 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. The difference between the premium and the fair value of the swaption is reported in unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations. If a swaption expires unexercised, the realized loss on the swaption would be equal to the premium paid and reported in realized gain on other derivatives and securities, net in our consolidated statements of operations. If we exercise a swaption, the realized gain or loss on the swaption would be equal to the difference between the fair value of the underlying interest rate swap and the premium paid and reported in realized gain on other derivatives and securities, net in our consolidated statements of operations.

Interest rate swaption agreements are privately negotiated in the OTC market and are not subject to central clearing. 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.

TBA securities

A TBA security is a forward contract for the purchase ("long position") or sale ("short position") of agency RMBS at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific agency RMBS delivered into the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association, are not known at the time of the transaction. We may enter into TBA contracts as a means of hedging

9

against short-term changes in interest rates. We may also enter into TBA contracts as a means of acquiring or disposing of agency RMBS and we may from time to time utilize TBA dollar roll transactions to finance agency RMBS purchases.

We account for all TBA contracts as derivatives since we cannot assert that it is probable at the inception and throughout the term of the contract that it will not settle net and will result in physical delivery of an agency security when it is issued. A TBA dollar roll transaction is a series of derivative transactions. The net settlement of a TBA contract is reported as realized gain on other derivatives and securities, net and changes in the fair value of our TBA contracts are reported as unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations.

We estimate the fair value of TBA securities based on similar methods used to value our agency RMBS.

Forward commitments to purchase or sell specified securities

We may enter into a forward commitment to purchase or sell specified securities as a means of acquiring assets or as a hedge against short-term changes in interest rates. Such forward commitments usually require physical settlement. Contracts for the purchase or sale of specified securities are accounted for as derivatives if the delivery of the specified agency RMBS and settlement extends beyond established market conventions. Realized gains and losses associated with forward commitments are recognized in realized gain on other derivatives and securities, net and unrealized gains and losses are recognized in unrealized gain (loss) on other derivatives and securities, net on our consolidated statements of operations.

We estimate the fair value of forward commitments to purchase or sell specified RMBS based on methods used to value our RMBS, as well as the remaining length of time of the forward commitment.

U.S. Treasury securities

We purchase or sell short 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. Realized gains and losses associated with purchases and short sales of U.S. Treasury securities and U.S. Treasury futures contracts are recognized in realized gain on other derivatives and securities, net, and unrealized gains and losses are recognized in unrealized gain (loss) on other derivatives and securities, net on our consolidated statements of operations.

As of September 30, 2014 and December 31, 2013, none of our agency RMBS had an estimated weighted average life of less than 3.4 years and 2.1 years, respectively. As of September 30, 2014 and December 31, 2013, the estimated weighted average life of our agency security portfolio was 7.1 years and 6.1 years, respectively, which incorporates anticipated future prepayment assumptions. As of September 30, 2014 and December 31, 2013, our weighted average expected constant prepayment rate ("CPR") over the remaining life of our aggregate agency investment portfolio was 8% and 7%, respectively. Our estimates differ materially for different types of securities and thus individual holdings have a wide range of projected CPRs. We estimate long-term prepayment rates using a third-party service and market data. We review the prepayment speeds estimated by the third-party service and compare the results to market consensus prepayment speeds, if available. We also consider historical prepayment speeds and current market conditions to validate reasonableness. As market conditions may change rapidly, we use our judgment in developing our estimates for different securities. Prepayments are dependent on many factors and actual prepayments could differ materially from our estimates. Various market participants could use materially different assumptions. Furthermore, changes in market conditions such as interest rates, housing prices, and broad economic factors such as employment can materially impact prepayments. Additionally, modifications to GSE underwriting criteria or programs, GSE policies surrounding the buyouts or modifications of delinquent loans or other factors could significantly change the prepayment landscape.

Our Prime non-agency RMBS include investments in securitization trusts collateralized by prime mortgage loans, which are residential mortgage loans that are considered to have been originated with the most stringent underwriting standards at the time of origination. Our Prime securities with a combined fair value of $175.6 million as of September 30, 2014 are collateralized by loans that were originated between 2003 and 2006, a period of generally weaker underwriting standards and elevated housing prices. As a result, there is still material credit risk embedded in these vintages. As of September 30, 2014, Prime securities also include $81.5 million in fair value of securities with underlying mortgage loans that were originated with more stringent underwriting during 2012 and 2013. As of September 30, 2014, our Prime securities have both floating-rate and

14

fixed-rate coupons ranging from 0.8% to 6.5%, with weighted average coupons of underlying collateral ranging from 2.4% to 5.8%.

Our Alt-A non-agency RMBS are collateralized by Alt-A mortgage loans that were originated from 2002 to 2007. Alt-A, or alternative A-paper, mortgage loans are considered to have more credit risk than prime mortgage loans and less credit risk than sub-prime mortgage loans. Alt-A loans are typically characterized by borrowers with less than full documentation, lower credit scores, higher loan-to-value ratios and a higher percentage of investment properties. As of September 30, 2014, our Alt-A securities have both fixed and floating rate coupons ranging from 0.2% to 6.5% with weighted average coupons of underlying collateral ranging from 2.7% to 6.9%.

Our Option-ARM non-agency RMBS include senior tranches in securitization trusts that are collateralized by residential mortgages that have origination and underwriting characteristics similar to Alt-A mortgage loans, with the added feature of providing underlying mortgage borrowers the option, within certain constraints, to make lower payments than otherwise required by the stated interest rate for a number of years, leading to negative amortization and increased loan balances. This additional feature can increase the credit risk of these securities. As of September 30, 2014, our Option-ARM securities have coupons ranging from 0.3% to 1.1% and have underlying collateral with weighted average coupons between 2.7% and 3.5%. The loans underlying our Option-ARM securities were originated between 2004 and 2007.

Our Subprime non-agency RMBS issued prior to 2013 include fixed and floating rate, senior tranches in securitization trusts collateralized by residential mortgages originated from 2003 to 2007 that were originally considered to be of lower credit quality. As of September 30, 2014, our Subprime securities issued prior to 2013 have a fair value of $139.6 million with fixed and floating rate coupons ranging from 0.2% to 5.4% and have underlying collateral with weighted-average coupons ranging from 4.5% to 7.8%. Additionally, we have classified certain non-performing loans that were securitized in 2013 and 2014 as Subprime securities. These 2013 and 2014 securitizations are backed by loans originated during or before 2010 and, as of September 30, 2014, have a fair value of $15.6 million. As of September 30, 2014, our Subprime securities issued in 2013 and 2014 have fixed rate coupons ranging from 3.3% to 4.3% and have underlying collateral with weighted-average coupons ranging from 5.7% to 8.4%.

More than 98% of our non-agency RMBS are rated below investment grade or have not been rated by credit agencies as of September 30, 2014.

Note 6. Repurchase Agreements

We pledge certain of our securities as collateral under repurchase arrangements with financial institutions, the terms and conditions of which are negotiated on a transaction-by-transaction basis. Interest rates on these borrowings are generally based on LIBOR plus or minus a margin and amounts 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. In response to declines in fair value of pledged securities, lenders may require us to post additional collateral or pay down borrowings to re-establish agreed upon collateral requirements, referred to as margin calls. As of September 30, 2014 and December 31, 2013, we have met all margin call requirements and had no agency or non-agency repurchase agreements with original overnight maturities. Repurchase agreements are carried at cost, which approximates fair value due to their short-term nature.

At September 30, 2014 and December 31, 2013, our borrowings under repurchase agreements had the following collateral characteristics (dollars in thousands):

	September 30, 2014					December 31, 2013
			Weighted Average					Weighted Average
Collateral Type	Borrowings Outstanding		Interest Rate		Days to Maturity	Borrowings Outstanding		Interest Rate		Days to Maturity

In addition, less than 5% of stockholders' equity was at risk due to collateral pledged in excess of borrowings under repurchase agreements with any one counterparty, with the top five counterparties representing less than 18% of our equity at risk as of September 30, 2014.

We had agency RMBS with fair values of $4.1 billion and $5.6 billion and non-agency RMBS with fair values of $0.8 billion and $0.9 billion pledged as collateral against repurchase agreements, as of September 30, 2014 and December 31, 2013, respectively.

Note 7. Derivatives and Other Securities

In connection with our risk management strategy, we hedge a portion of our exposure to market risks, including interest rate risk and prepayment risk, by entering into derivative and other hedging instrument contracts. We may enter into agreements for interest rate swaps, interest rate swaptions, interest rate cap or floor contracts and futures or forward contracts. We may also purchase or short TBA and U.S. Treasury securities, purchase or write put or call options on TBA securities or we may invest in other types of derivative securities, including synthetic total return swaps and credit default swaps. Our risk management strategy attempts to manage the overall risk of the portfolio and reduce fluctuations in book value. We do not use derivative or other hedging instruments for speculative purposes. Derivatives have not been designated as hedging instruments. We do not offset our derivatives and related cash collateral with the same counterparties under any master netting arrangements. For additional information regarding our derivative instruments and our overall risk management strategy, please refer to the discussion of derivatives in Note 3 - Summary of Significant Accounting Policies.

Interest Rate Swap Agreements

As of September 30, 2014 and December 31, 2013, our derivative portfolio included interest rate swaps, which have the effect of modifying the repricing characteristics of our repurchase agreements and cash flows on such liabilities. Our interest rate swaps are used to manage the interest rate risk created by our use of short-term repurchase agreements. Under our interest rate swaps, we typically pay a fixed rate and receive a floating rate based on LIBOR with terms usually ranging up to 15 years. As of September 30, 2014 and December 31, 2013, we had interest rate swap agreements summarized in the tables below (dollars in thousands).

⁽¹⁾  Notional amount represents the par value or principal balance of the underlying agency security.

⁽²⁾  Fair value represents the current market value of the agency RMBS underlying the TBA contract as of period end, less the forward price to be paid for the underlying agency RMBS.

U.S. Treasury Securities and Futures

We purchase or sell short 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 had U.S. Treasury securities with a fair value of $467.2 million and $637.3 million and a face amount of $472.0 million and $656.0 million as of September 30, 2014 and December 31, 2013, respectively, which is presented as Treasury securities, at fair value on the consolidated balance sheets. In addition, we had a short position in U.S. Treasury futures with a fair value of $1.2 million and $3.4 million, respectively, and a notional amount of $(150.0) million as of both September 30, 2014 and December 31, 2013, which is presented in derivative assets, at fair value on the consolidated balance sheets.

We had obligations to return U.S. Treasury securities borrowed under reverse repurchase agreements accounted for as securities borrowing transactions with a fair value of $742.6 million and $22.5 million as of September 30, 2014 and December 31, 2013, respectively. The borrowed securities were collateralized by cash payments of $745.4 million and $22.7 million as of September 30, 2014 and December 31, 2013, respectively, which are presented as receivables under reverse repurchase agreements on the consolidated balance sheets. All changes in fair value of long and short U.S. Treasury securities and futures are recorded in unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations.

REIT Equity Securities, at Fair Value

As of December 31, 2013, we held shares of common stock of several publicly-traded mortgage REITs with a cost basis of $39.3 million and a total fair value of $38.8 million. As of September 30, 2014, we no longer held any positions in these securities and for the nine months ended September 30, 2014, we recognized $6.8 million of net realized gains on disposal and $1.8 million in dividend income which are both included in realized gain on other derivatives and securities, net in our consolidated statements of operations.

Credit Risk-Related Contingent Features

The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. We minimize this risk by limiting our counterparties for instruments which are not centrally cleared on a registered exchange to major financial institutions with acceptable credit ratings and monitoring positions with individual counterparties. In addition, both we and our counterparties may be required to pledge assets as collateral for our derivatives, whose amounts vary over time based on the market value, notional amount and remaining term of the derivative contract. In the event of a default by a counterparty, we may not receive payments provided for under the terms of our derivative agreements, and may have difficulty obtaining our assets pledged as

21

collateral for our derivatives. The cash and cash equivalents pledged as collateral for our derivative instruments is included in restricted cash and cash equivalents on our consolidated balance sheets.

Each of our ISDA Master Agreements contains provisions pursuant to which we are required to fully collateralize our obligations under our interest rate swap agreements if at any point the fair value of the swap represents a liability greater than the minimum transfer amount contained within our ISDA Master Agreements. We are also required to post initial collateral upon execution of certain of our swap transactions. If we breach any of these provisions, we will be required to settle our obligations under the agreements at their termination values, which approximates fair value.

Further, each of our ISDA Master Agreements also contains a cross default provision under which a default under certain of our other indebtedness in excess of a certain threshold causes an event of default under the agreement. Threshold amounts vary by lender. Following an event of default, we could be required to settle our obligations under the agreements at their termination values. Additionally, under certain of our ISDA Master Agreements, we could be required to settle our obligations under the agreements at their termination values if we fail to maintain either our REIT status or certain minimum stockholders’ equity thresholds, or comply with limits on our leverage above certain specified levels. As of September 30, 2014, the fair value of the 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 consolidated financial statements.

Concerning our non-centrally cleared interest rate swap and swaption agreements, we did not have counterparty credit risk with any single counterparty in excess of 1% of our stockholders’ equity, as of September 30, 2014.

In the case of centrally cleared interest rate swap contracts, 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, the risk is considered minimal due to initial and daily exchange of mark to market margin requirements and the clearinghouse guarantee fund and other resources that are available in the event of a clearing member default.

Note 8. Offsetting Assets and Liabilities

Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of offset 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 such agreements and can potentially be offset on our consolidated balance sheets as of September 30, 2014 and December 31, 2013 (in thousands):

Note 9. Fair Value Measurements

We have elected the option to account for all of our financial assets, including RMBS, at fair value, with changes in fair value reflected in income during the period in which they occur. We have determined that this presentation most appropriately represents our financial results and position. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, based on the assumptions market participants would use when pricing an asset or liability.

We determine the fair value of our agency and non-agency RMBS, including securities held as collateral, 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 recent trading activity, 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, default and loss severity, especially when estimating fair values for securities with lower levels of recent trading activity. When possible, we make inquiries of third-party pricing sources to understand their use of significant inputs and assumptions.

We review the various third-party fair value estimates and perform procedures to validate their reasonableness, including an analysis of the range of third-party estimates for each position, comparison to recent trade activity for similar securities, and our Manager's review 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 determination of fair value if we determine (based on our validation procedures and our Manager's market knowledge and expertise) that the price is significantly different than observable market data would indicate and we cannot obtain a satisfactory understanding from the third party source as to the significant inputs used to determine the price.

We determine the fair value of our MSR based upon discounted cash flow models that are primarily based on observable market-based inputs but also include substantial unobservable market data inputs (including prepayment speeds, delinquency levels and discount rates).

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. We

23

use the results of the validation procedures described above as part of our determination of the appropriate fair value measurement hierarchy classification. The three levels of 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 - Significant unobservable market inputs that are supported by little or no market activity. The unobservable inputs represent the assumptions that market participants would use to price the assets and liabilities.

The following tables present our financial instruments carried at fair value as of September 30, 2014 and December 31, 2013, on the consolidated balance sheets by the valuation hierarchy, as described above (in thousands):

Our agency and non-agency RMBS are valued using the various market data described above, which include inputs determined to be observable or whose significant value drivers are observable. Accordingly, our agency and non-agency RMBS are classified as Level 2 in the fair value hierarchy as of September 30, 2014. We estimate the fair value of our REIT equity securities on a market approach using Level 1 inputs, based on quoted market prices.

For information regarding valuation of our derivative instruments, please refer to the discussion of derivative and other hedging instruments in Note 3. Our interest rate swaps and other derivatives are classified as Level 2 in the fair value hierarchy.

The fair value of our obligation to return securities borrowed under reverse repurchase agreements is based upon the value of the underlying borrowed U.S. Treasury securities as of the reporting date. Both U.S. Treasury securities and our obligation to return borrowed U.S. Treasury securities are classified as Level 1 in the fair value hierarchy.

The following table presents a summary of the changes in fair value for Level 3 assets carried at fair value as of September 30, 2014 (in thousands):

	For the Nine Months Ended September 30, 2014

————————

⁽¹⁾ Gains (losses) included in net income related to MSR under secured financing are offset in their entirety by (losses) gains associated with related MSR financing liabilities.

We use third-party pricing providers in the fair value measurement of our Level 3 MSR. The significant unobservable inputs used in estimating the fair value measurement of our Level 3 MSR assets and financing liabilities include assumptions for underlying loan constant prepayment rates and delinquency rates, as well as discount rates. We review the various third-party fair value estimates used to determine the fair value of our MSR and perform procedures to validate their reasonableness. In reviewing the estimated fair values of our Level 3 MSR, we use internal models and our own estimates of prepayment and

delinquency rates on the loans underlying our MSR.

The following table presents the range of our estimates of loan constant voluntary prepayment rates and constant default rates, together with the discount rates used by third-party pricing providers in estimating the fair value of our Level 3 MSR as of September 30, 2014 (dollars in thousands):

	September 30, 2014
Unobservable Level 3 Input	Fair Value		Minimum	Weighted Average	Maximum
MSR treated as financing arrangements:	$	14,470
Constant prepayment rate			9.7%	14.7%	34.5%
Constant default rate			—%	7.4%	28.2%
Discount rate			16.0%	16.0%	16.0%
Purchased MSR:	85,844
Constant prepayment rate			7.3%	7.7%	8.1%
Constant default rate			0.2%	0.3%	0.4%
Discount rate			8.3%	8.7%	9.3%
Total	$	100,314

25

Our MSR treated as financing arrangements relate to private label mortgages with an average origination year of 2005, whereas our purchased MSR relate to more recently originated mortgages that conform to GSE underwriting standards. Private label originations from the pre-2009 era have experienced heightened default rates relative to recently originated conforming mortgages. As such, we anticipate that the default rate and discount rate for our MSR treated as financing arrangements will exceed the default rate and discount rate for our purchased MSR.

A significant increase in any one of these individual inputs in isolation would likely result in a decrease in fair value measurement. Additionally, a change in the assumption used for discount rates may be accompanied by a directionally similar change in the assumption used for the probability of delinquency and a directionally opposite change in the assumption used for prepayment rates. Overall MSR market conditions could have a more significant impact on our Level 3 fair values than changes in any one unobservable input.

Note 10. Mortgage Servicing Rights

Our $100.3 million balance of MSR as of September 30, 2014 includes $14.5 million related to RCS' acquisition of certain MSR covering private label residential mortgage pools, for which RCS entered into sale and assignment agreements with a third party to transfer its interest in the excess MSR while retaining the actual servicing function. These transfers do not qualify for sale accounting and are treated as financing arrangements, under which we recognize both MSR assets and MSR corresponding MSR financing liabilities. Changes in the fair value of assets and liabilities resulting from MSR financing transactions have no net impact on the consolidated statements of operations.

The remaining $85.8 million of MSR were purchased by RCS during the nine months ended September 30, 2014 under transactions qualifying for sale accounting, representing approximately 34,608 underlying loans, with a combined unpaid principal balance of approximately $7.3 billion as of September 30, 2014. We have elected to account for all MSR assets and MSR financing liabilities at estimated fair value with changes in fair value reported in net income. The following table summarizes activity related to MSR accounted for as purchases during the nine months ended September 30, 2014 (dollars in thousands):

	For the Nine Months Ended September 30, 2014
Balance as of December 31, 2013	$	—
Additions from purchases of MSR	93,414
Changes in fair value due to:

Risk Mitigation Activities

The Company’s acquisitions of MSR expose us to certain risks, including interest rate risk and representation and warranty risk. A significant decline in interest rates could lead to higher-than-expected prepayments that could reduce the value of the MSR. Our primary method of managing the prepayment risk associated with our MSR portfolio is asset selection, both in respect of products and the originators of the underlying loans. Representation and warranty risk refers to the representations and warranties we make (or are deemed to have made) to the applicable investor (including, without limitation, the GSEs) regarding, among other things, the origination and servicing of mortgage loans with respect to which we have acquired MSR. We mitigate representation and warranty risk through our due diligence in connection with MSR acquisitions, including counterparty reviews and loan file reviews, as well as negotiated contractual protections from our MSR transaction counterparties with respect to origination and prior servicing.

Note 13. Stockholders’ Equity

Preferred Stock Offering

Pursuant to our charter, we are authorized to designate and issue up to 50.0 million shares of preferred stock in one or more classes or series. Our Board of Directors has designated 2.3 million shares as 8.125% Series A Cumulative Redeemable Preferred Stock ("Series A Preferred Stock"). As of September 30, 2014, we have 47.8 million of authorized but unissued shares of preferred stock. Our Board of Directors may designate additional series of authorized preferred stock ranking junior to or in parity with the Series A Preferred Stock or designate additional shares of the Series A Preferred Stock and authorize the issuance of such shares.

In May 2014, we completed a public offering in which 2.2 million shares of our Series A Preferred Stock were sold to the underwriters at a price of $24.2125 per share. Upon completion of the offering we received proceeds, net of offering expenses, of approximately $53.0 million. Our Series A Preferred Stock has no stated maturity and is not subject to any sinking fund or mandatory redemption. Under certain circumstances upon a change of control, the Series A Preferred Stock is convertible to shares of our common stock. Holders of Series A Preferred Stock have no voting rights, except under limited conditions, and holders are entitled to receive cumulative cash dividends at a rate of 8.125% per annum of the $25.00 per share liquidation preference before holders of our common stock are entitled to receive any dividends. Shares of our Series A Preferred Stock are redeemable at $25.00 per share plus accumulated and unpaid dividends (whether or not declared) exclusively at our option commencing on May 22, 2019, or earlier under certain circumstances intended to preserve our qualification as a REIT for Federal income tax purposes. Dividends are payable quarterly in arrears on the 15th day of each January, April, July and October. As of September 30, 2014, we had declared all required quarterly dividends on the Series A Preferred Stock.

28

Stock Repurchase Program

In October 2012, our Board of Directors adopted a program that provided for stock repurchases of up to $50 million of our outstanding shares of common stock through December 31, 2013. In June 2013, our Board of Directors authorized the repurchase of up to an additional $100 million of our outstanding shares of common stock through December 31, 2013. In September 2013, our Board of Directors authorized the repurchase of up to an additional $150 million of our outstanding shares of common stock and extended its authorization through December 31, 2014. In October 2014, our Board of Directors extended the Company's existing stock repurchase program through December 31, 2015.

We did not repurchase any shares of our common stock during the three months ended September 30, 2014. During the nine months ended September 30, 2014, we repurchased approximately 0.2 million shares of our common stock at an average repurchase price of $19.67 per share, including expenses, totaling $4.2 million. As of September 30, 2014, we had an additional $134.9 million available for repurchases of our common stock through December 31, 2015, as authorized by the Board of Directors.

Dividend Reinvestment and Direct Stock Purchase Plan

We sponsor a dividend reinvestment and direct stock purchase plan through which stockholders may purchase additional shares of our common stock by reinvesting some or all of the cash dividends received on shares of our common stock. Stockholders may also make optional cash purchases of shares of our common stock subject to certain limitations detailed in the plan prospectus. We did not issue any shares under the plan during the three and nine months ended September 30, 2014.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") provides readers of our consolidated financial statements a narrative from the perspective of management, and should be read in conjunction with the consolidated financial statements and accompanying notes included in this Quarterly Report on Form 10-Q for the three months ended September 30, 2014. Our MD&A is presented in six sections:

• Executive Overview

• Financial Condition

• Results of Operations

• Liquidity and Capital Resources

• Off-Balance Sheet Arrangements

• Forward-Looking Statements

EXECUTIVE OVERVIEW

The size and composition of our investment portfolio depend on investment strategies implemented by our Manager, the availability of investment capital and overall market conditions, including the availability of attractively priced investments and suitable financing to appropriately leverage our investment portfolio. Market conditions are influenced by, among other things, current levels of and expectations for future levels of, interest rates, mortgage prepayments, market liquidity, housing prices, unemployment rates, general economic conditions, government participation in the mortgage market, evolving regulations or legal settlements that impact servicing practices or other mortgage related activities.

Our Investment Strategy

Our objective is to provide attractive risk-adjusted returns to our stockholders over the long-term through a combination of dividends and net book value appreciation. In pursuing this objective, we rely on our Manager's expertise to construct and manage a diversified mortgage investment portfolio by identifying asset classes that, when properly financed and hedged, are selected to produce attractive returns across a variety of market conditions and economic cycles, considering the risks associated with owning such investments. Specifically, our investment strategy is designed to:

• manage a leveraged investment portfolio of mortgage-related investments to generate attractive risk-adjusted returns;

• capitalize on discrepancies in the relative valuations in the mortgage-related investments market;

• manage financing, interest rate, prepayment rate and credit risks;

• preserve our net book value;

• provide regular quarterly distributions to our stockholders;

• qualify as a REIT; and

• remain exempt from the requirements of the Investment Company Act of 1940, as amended (the "Investment Company Act").

Our Risk Management Strategy

We use a variety of strategies to hedge a portion of our exposure to market risks, including interest rate, prepayment, extension and credit risks to the extent that our Manager believes is prudent, taking into account our investment strategy, the cost of the hedging transactions and our intention to qualify as a REIT. As a result, we may not hedge certain interest rate, prepayment, extension or credit risks if our Manager believes that bearing such risks enhances our return relative to our risk/return profile, or would negatively impact our REIT status.

• Interest Rate Risk. We hedge some of our exposure to potential interest rate mismatches between the interest we earn on our longer term investments and the interest we pay on our shorter term borrowings. Because a majority of our funding is in the form of repurchase agreements, our financing costs fluctuate based on short-term interest rate indices, such as the London Interbank Offered Rate, or LIBOR. Because the vast majority of our investments are assets that have fixed rates of interest and could mature in up to 40 years, the interest we earn on those assets generally does not move in tandem with the interest rates that we pay on our repurchase agreements, which generally have a maturity of less than one year. We may experience reduced income, losses, or a significant reduction in our book value due to adverse interest rate movements. In order to attempt to mitigate a portion of such

30

risk, we utilize certain hedging techniques to attempt to lock in a portion of the net spread between the interest we earn on our assets and the interest we pay on our financing costs.

Additionally, because prepayments on residential mortgages generally accelerate when interest rates decrease and slow when interest rates increase, mortgage securities typically have "negative convexity." In other words, certain mortgage securities in which we invest may increase in price more slowly than similar duration bonds, or even fall in value, as interest rates decline. Conversely, certain mortgage securities in which we invest may decrease in value more quickly than similar duration bonds as interest rates increase. In order to manage this risk, we monitor, among other things, the "duration gap" between our mortgage assets and our hedge portfolio as well as our convexity exposure. Duration is an estimate of the relative expected percentage change in market value of our mortgage assets or our hedge portfolio that would be caused by a parallel change in short and long-term interest rates. Convexity exposure relates to the way the duration of our mortgage assets or our hedge portfolio changes when the interest rate or prepayment environment changes.

The value of our mortgage assets may also be adversely impacted by fluctuations in the shape of the yield curve or by changes in the market's expectation about the volatility of future interest rates. We analyze our exposure to non-parallel changes in interest rates and to changes in the market's expectation of future interest rate volatility and take actions to attempt to mitigate these risks.

• Prepayment Risk. Because residential borrowers have the option to prepay their mortgage loans at par at any time, we face the risk that we will experience a return of principal on our investments faster than anticipated. Prepayment risk generally increases when interest rates decline. In this scenario, our financial results may be adversely affected as we may have to invest returned principal at lower yields.

• Extension Risk. Because residential borrowers have the option to make only scheduled payments on their mortgage loans, rather than prepay their mortgage loans, we face the risk that a return of capital on our investment will occur slower than anticipated. Extension risk generally increases when interest rates rise. In this scenario, our financial results may be adversely affected as we may have to finance our investments at potentially higher costs without the ability to reinvest principal into higher yielding securities.

• Credit Risk. We accept mortgage credit exposure at levels our Manager deems prudent within the context of our diversified investment strategy. Therefore, we may retain all or a portion of the credit risk on the loans underlying our non-agency RMBS, as well as any future investments in CMBS and individual residential and commercial mortgages. We seek to manage this risk through prudent asset selection, pre-acquisition due diligence, post-acquisition performance monitoring, and sale of assets where we identify negative credit trends. We may also manage credit risk with credit default swaps or other financial derivatives that our Manager believes are appropriate. Additionally, we vary the percentage mix of our non-agency mortgage investments and agency mortgage investments in an effort to actively adjust our credit exposure and to improve the risk/return profile of our investment portfolio.

The principal instruments that we use to hedge a portion of our exposure to interest rate, prepayment and extension risks are interest rate swaps and options to enter into interest rate swaps ("interest rate swaptions"). We also utilize forward contracts for the purchase or sale of agency RMBS on a generic pool, or a TBA contract, basis and on a non-generic, specified pool basis, and we utilize U.S. Treasury securities and U.S. Treasury futures contracts, primarily through short sales. We may also purchase or write put or call options on TBA securities and we may invest in other types of mortgage derivatives, such as interest and principal-only securities.

Our hedging instruments are generally not designed to protect our net book value from "spread risk" (also referred to as "basis risk"), which is the risk of an increase of the market spread between the yield on our agency RMBS and the benchmark yield on U.S. Treasury securities or interest rate swap rates. The inherent spread risk associated with our agency RMBS and the resulting fluctuations in fair value of these securities can occur independent of 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 U. S. Federal Reserve ("Fed"), 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 our net book value against moves in interest rates, such instruments typically will not protect our net book value against spread risk and, therefore, the value of our agency RMBS and our net book value could decline.

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

31

provide protection against larger rate moves and as a result may be relatively ineffective for smaller changes in interest rates. There can be no certainty that our Manager's projections of our exposures to interest rates, prepayments, extension, credit or other risks will be accurate or that our hedging activities will be effective and, therefore, actual results could differ materially.

Income from hedging transactions that we enter into to manage risk may not constitute qualifying gross income under one or both of the gross income tests applicable to REITs. Therefore, we may have to limit our use of certain advantageous hedging techniques, which could expose us to greater risks than we would otherwise want to bear, or implement those hedges through a taxable REIT subsidiary ("TRS"). Implementing our hedges through a TRS could increase the cost of our hedging activities because a TRS is subject to tax on income and gains.

Trends and Recent Market Impacts

The fixed income markets were relatively stable during the first three quarters of 2014, a sharp contrast to the extreme interest rate volatility and price deterioration experienced in 2013. The consensus view at the start of 2014 was that interest rates would continue to increase and agency RMBS spreads would widen as the Fed exited its third quantitative easing program ("QE3"). Weaker economic data and lower inflation expectations both domestically and abroad, however, led to a significant rally in interest rates and a flattening of the yield curve. Despite this unexpected movement in interest rates and the Fed’s gradual reduction of asset purchases, agency RMBS outperformed other fixed income products over the first three quarters of 2014.

The relative outperformance of agency RMBS and the continued improvement in non-agency RMBS were the primary drivers of our aggregate economic return of 12.7% for the first three quarters of 2014, comprised of $1.95 of dividends per common share and a $0.77 increase in our net book value per common share. The strong performance of agency RMBS over this time period was driven by historically low mortgage origination volume, conservative portfolio positioning by fixed income investors who remain underweight agency RMBS, and the favorable "stock effect" of the Fed's ownership of a significant portion of the agency RMBS market as of September 30, 2014. Our performance also benefited from our active approach to portfolio management, which included repositioning our asset portfolio, modifying the composition of our hedge portfolio and operating with a larger duration gap (the estimated difference between the interest rate sensitivity of our assets and our liabilities and hedges).

By the start of 2014, we had increased our 15 year fixed rate mortgage position to approximately 44% of our agency RMBS portfolio, which benefited our first quarter performance, as 15 year RMBS generally outperformed 30 year RMBS during the first quarter on a hedge adjusted basis. In the second quarter, the price of higher coupon 15 year agency RMBS increased significantly relative to other agency RMBS instruments. In response to this strong relative performance, we reduced our 15 year position in favor of 30 year mortgages over the second and third quarters. As of September 30, 2014, 30 year mortgages represented 53% of our agency RMBS portfolio, a significant increase from 47% as of March 31, 2014.

Our performance during the first three quarters of 2014 also benefited from favorable financing terms available in the TBA dollar roll market. Given the attractiveness of TBA investments, we allocated a larger portion of our portfolio to TBA securities, rather than holding our investments in pool form funded by repurchase agreements. For the first three quarters of 2014, our average TBA dollar roll position was $0.6 billion, or approximately 9% of our investment portfolio, compared to our $(0.8) billion net short position as of December 31, 2013.

Our decision to operate with a slightly larger duration gap during the first three quarters of 2014 was consistent with our moderate leverage profile, the asymmetry of our duration gap between contraction and extension risks, and our assessment of the correlation between mortgage spreads and interest rates. When extension risk is viewed as more significant, we will tend to operate with a smaller duration gap. When extension risk is deemed less significant, we will tend to operate with a larger duration gap. (For further discussion of our interest rate sensitivity, refer to Quantitative and Qualitative Disclosures about Market Risk in this Form 10-Q.) In contrast to the spread correlation that we experienced in 2013, agency RMBS performance has generally been inversely correlated with interest rate changes through the first three quarters of 2014, as spreads have widened when rates fell and tightened when rates rose. When agency RMBS spreads are inversely correlated with interest rates, we tend to operate with a positive duration gap, and when spreads are positively correlated with interest rates, we tend to operate with a very small or negative duration gap.

Looking ahead, we believe our portfolio is well positioned for a wide range of interest rate scenarios. In a declining rate environment, our significant holding of assets with favorable prepayment characteristics should gain in value relative to other mortgage investments. As of September 30, 2014, 86% of our fixed-rate agency investments, or 70% including net TBA mortgage positions, were comprised of loans with slower prepayment attributes (e.g., loans originated under the U.S. Government sponsored Home Affordable Refinance Program, or “HARP”, and mortgage pools backed by lower loan balances), providing our portfolio with a significant amount of prepayment protection in a lower rate environment. In a rising rate

32

environment, agency RMBS valuations should benefit from lower supply dynamics. In addition, we believe that the Fed will remain a significant purchaser of agency RMBS given its stated policy to reinvest paydowns on its portfolio into new agency RMBS holdings for a considerable time following the conclusion of QE3 in the fourth quarter of 2014. Finally, we believe TBA dollar roll financing will remain attractive for some period of time, even if funding rates were to rise above, or become less “special” than, levels experienced during the first three quarters of 2014.

However, if conditions change resulting in higher interest rates and/or wider mortgage spreads, it would likely have an adverse impact on our net book value, assuming we took no further portfolio rebalancing actions. (For the estimated impact of changes in interests rates and mortgage spreads on our net book value please refer to Quantitative and Qualitative Disclosures about Market Risk in this Form 10-Q.) Furthermore, since we employ an active management strategy, the size and composition of our assets, liabilities and hedges will evolve based on our Manager’s view of the current market environment and relative risks and rewards and, consequently, the actual impact of changes in interest rates and mortgage spreads could differ materially from our estimates.

The market for legacy non-agency RMBS performed well throughout the first three quarters of 2014, as the housing market continued its gradual recovery and as favorable supply and demand fundamentals put upward pressure on valuations. Although the rate of house price appreciation is beginning to decelerate, the shrinking supply of legacy non-agency RMBS remains supportive of credit spreads. The non-agency market is now under $750 billion in unpaid principal balance, representing a decline of roughly 12% year over year. Additionally, improving loan-to-value ratios, falling delinquency rates and reduced sensitivity to servicer behavior should lead to a further stabilization in cashflow projections. While we continue to have a generally optimistic view of the non-agency RMBS sector, we recognize the potential for housing market weakness. Additionally, we believe the possibility for volatility in less liquid areas of the fixed income markets has increased. As such, while we have grown our non-agency portfolio to $1,075.9 million at September 30, 2014 from $1,011.2 million at December 31, 2013, we have increased our allocation to categories of non-agency RMBS that we believe would provide more stability in a wider range of housing scenarios.

In November 2013, we acquired Residential Credit Solutions, Inc. ("RCS"), a fully-licensed mortgage servicer based

in Fort Worth, Texas that has approvals from Fannie Mae, Freddie Mac, and Ginnie Mae to hold and manage MSR and residential mortgage loans. During the first three quarters of 2014, we purchased approximately $93 million in MSR with an underlying loan unpaid principal balance of approximately $7 billion. We expect our acquisition of MSR to be measured over the remainder of the year as we work to identify additional opportunities that are appropriately priced, with acceptable levels of exposure to adverse prepayment behavior and counterparty risk.

Summary of Critical Accounting Estimates

Our critical accounting estimates relate to the fair value of our investments and derivatives and recognition of interest income. Certain of these items involve estimates that require management to make judgments that are subjective in nature. We rely on our Manager's experience and analysis of historical and current market data in order to arrive at what we believe to be reasonable estimates. Under different conditions, we could report materially different amounts using these critical accounting policies. All of our critical accounting policies are fully described in our MD&A in our Annual Report on Form 10-K for the year ended December 31, 2013. Our significant accounting policies are described in Note 3 to the consolidated financial statements included under Item 1 of this Quarterly Report on Form 10-Q.

We have elected the option to account for all of our financial assets, including all mortgage-related investments, at fair value, with changes in fair value reflected in income during the period in which they occur. We believe this election more appropriately reflects the results of our operations for a particular reporting period, as financial asset fair value changes are presented in a manner consistent with the presentation and timing of the fair value changes of hedging instruments.

FINANCIAL CONDITION

As of September 30, 2014, our investment portfolio with a fair value of $6.4 billion consisted of $4.3 billion of agency RMBS, $0.9 billion in net long TBA positions, $1.1 billion of non-agency RMBS and $0.1 billion MSR. Our investment portfolio increased $0.5 billion from $5.9 billion as of December 31, 2013 due primarily to the combination of fair value gains on our agency and non-agency investments and $53 million in net proceeds from our Series A Preferred Stock offering.

Our TBA positions are recorded as derivative instruments in our accompanying consolidated financial statements, with the TBA dollar roll transactions representing a form of off-balance sheet financing. As of September 30, 2014, our net TBA position had a net carrying value of $(2.1) million reported in derivative assets/(liabilities) on our consolidated balance sheets. The net carrying value represents the difference between the fair value of the underlying agency security in the TBA contract and the cost basis or the forward price to be paid or received for the underlying agency security.

The table below presents our condensed consolidated balance sheets as of September 30, 2014 and December 31, 2013 (dollars in thousands, except per share amounts):

Agency RMBS

As detailed in the tables below, the weighted average agency RMBS portfolio yield increased slightly, while the weighted average projected CPR increased by approximately 1 percentage point from December 31, 2013 to September 30, 2014. The relative stability in the agency RMBS portfolio yield resulted from our rebalancing of the portfolio towards a larger percentage of higher-yielding, 30-year securities and away from lower yielding 15-year securities.

⁽¹⁾  HARP securities are defined as pools backed by 100% refinance loans with LTVs greater than or equal to 80%. Our HARP securities had a weighted average LTV of 107% and 115% for 15-year and 30-year securities, respectively, as of December 31, 2013. Includes $492.1 million of >105% LTV pools which are not deliverable into TBA securities.

⁽²⁾  Lower loan balance securities represent pools with maximum original loan balances less than or equal to $150,000. Our lower loan balance securities had a weighted average original loan balance of $101,106 and $87,238 for 15-year and 30-year securities, respectively, as of December 31, 2013.

The following table summarizes our agency RMBS at fair value according to their estimated weighted average life classifications as of September 30, 2014 and December 31, 2013 (dollars in thousands):

Actual maturities of agency RMBS are generally shorter than stated contractual maturities primarily as a result of prepayments of principal of the underlying mortgages. The stated contractual final maturity of the mortgage loans underlying our portfolio of securities can range up to 40 years, but the expected maturity is subject to change based on the actual and expected future prepayments of the underlying mortgage loans.

In determining the estimated weighted average years to maturity and yields on our agency RMBS, we estimate the percentage of outstanding principal that is expected to be prepaid over a period of time on an annualized basis, or CPR, based on assumptions for each security using a combination of a third-party service, market data and internal models. The third-party service estimates prepayment speeds using models that incorporate the forward yield curve, mortgage rates, current mortgage rates of the outstanding loans, loan age, volatility and other factors. We have estimated that the CPR over the remaining life of our aggregate agency investment portfolio was 8% and 7% as of September 30, 2014 and December 31, 2013, respectively. However, the weighted average expected life of our agency RMBS increased to 7.1 years as of September 30, 2014, from 6.1 years as of December 31, 2013, primarily as a result of rebalancing our portfolio towards a higher percentage of 30-year agency RMBS, with a lower percentage of 15-year agency RMBS. We amortize or accrete premiums and discounts associated with purchases of our agency RMBS into interest income over the estimated life of our securities based on projected CPRs, using the effective yield method. Since the weighted average cost basis of our agency RMBS portfolio was 104.4% of par value as of September 30, 2014, slower actual or projected prepayments can have a meaningful positive impact on our asset yields, while faster actual or projected prepayments can have a meaningful negative impact on our asset yields.

Non-Agency Investments

Non-agency RMBS yields are based on our estimate of the timing and amount of future cash flows and our cost basis. Our 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 and the timing and amount of credit losses and other factors.

Our non-agency RMBS are subject to risk of loss with regard to principal and interest payments. As of September 30, 2014 and December 31, 2013, our non-agency RMBS were generally either assigned below investment grade ratings by rating agencies, or were not rated. Credit ratings are based on the par value of the non-agency RMBS. However, the non-agency RMBS in our portfolio were generally purchased at a significant discount to par value. The following table summarizes the credit ratings of our non-agency RMBS as of September 30, 2014 and December 31, 2013:

Credit Rating (1)	September 30, 2014		December 31, 2013
AAA	1	%	5	%

⁽¹⁾ Represents the lowest of Standard and Poor's, Moody's and Fitch credit ratings, stated in terms of the S&P equivalent, as of each respective balance sheet date.

We evaluate each investment based on the characteristics of the underlying collateral and securitization structure, rather than relying on rating agencies. These securities were collateralized by mortgages with original weighted average amortized loan to value ratios ("LTV") of 75% as of both September 30, 2014 and December 31, 2013. However, as the home values associated with these mortgages have generally experienced significant price declines since origination and LTV is calculated based on the original home values, we believe that current market-based LTV would be significantly higher. Additionally, as of September 30, 2014 and December 31, 2013, 18% and 22% of the mortgages underlying these securities were either 60 or more days delinquent, undergoing foreclosure or bankruptcy processes, or held as real estate owned by the trusts. Credit enhancement, or protection provided at the security level to absorb future credit losses due to defaults on underlying collateral is another important component of this evaluation. Our non-agency RMBS had weighted average credit enhancements of 8% as of both September 30, 2014 and December 31, 2013.

⁽¹⁾ FICO represents a mortgage industry accepted credit score of a borrower based on a scale of 300 to 850 with a score of 850 being the highest quality rating.

⁽²⁾  60+ day delinquent represents the percentage of mortgage loans underlying each category of non-agency RMBS that were delinquent for at least 60 days.

⁽³⁾  Three-month CPR is reflective of the prepayment and default rate on the underlying securitization; however, it does not necessarily indicate the proceeds received on our non-agency RMBS. Proceeds received for each security are dependent on the position of the individual security within the structure of each deal.    

⁽⁴⁾  Prime non-agency RMBS include interest only investments with a fair value of $12.4 million and $11.0 million, and a current face value of $198.3 million and $206.4 million as of September 30, 2014 and December 31, 2013, respectively. The prime non-agency RMBS average purchase price presented in the table excludes interest only investments with a weighted average purchase price of $4.31 as of September 30, 2014 and December 31, 2013, respectively.    

The mortgage loans underlying our non-agency RMBS are located throughout the United States. The following table presents the five states with the largest geographic concentrations of underlying mortgages as of September 30, 2014 and December 31, 2013:

Mortgage Servicing Rights

On November 27, 2013, one of our wholly-owned subsidiaries acquired RCS, which has approvals from Fannie Mae, Freddie Mac and Ginnie Mae to hold and manage MSR. The MSR acquired in conjunction with this acquisition and those subsequently purchased represent the right to service mortgage loans. We did not originate the mortgage loans underlying our MSR. As of September 30, 2014, our MSR purchased during the year had a fair market value of $85.8 million.

The following table summarizes certain characteristics as of September 30, 2014 of the loans underlying our purchased MSR:

RESULTS OF OPERATIONS

Non-GAAP Financial Measures

In addition to the results presented in accordance with GAAP, our results of operations discussed herein include certain non-GAAP financial information, including "net spread and dollar roll income" (which includes the periodic interest rate costs of our interest rate swaps, TBA dollar roll income and dividends from REIT equity securities reported in other gains (losses), net in our consolidated statements of operations) and “estimated taxable income” and certain financial metrics derived from non-GAAP information, such as “cost of funds” and “estimated undistributed taxable income.” By providing users of our financial information with such measures in addition to the related GAAP measures, we intend to provide users greater transparency into the information used by our management in its financial and operational decision-making. We believe net spread and dollar roll income is meaningful information to consider as it incorporates the economic costs of financing our investment portfolio inclusive of interest rate swaps used to economically hedge against fluctuations in our borrowing costs and presents our current financial performance without the effects of certain transactions that are not necessarily indicative of our current investment portfolio and operations. We present estimated taxable income and estimated undistributed taxable income, as this information is directly related to the amount of dividends we will be required to distribute over time in order to maintain our REIT qualification status. However, because each of these non-GAAP disclosures 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, our 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 titled measures provided by other companies. Furthermore, estimated taxable income can include certain information that is subject to potential adjustments up to the time of filing our income tax returns, which occurs after the end of our fiscal year.

⁽¹⁾   Variances that are the combined effect of volume and yield, but cannot be separately identified, are allocated to the volume and yield variances based on their respective relative amounts.

Interest income on agency RMBS decreased by $(27.4) million during the three months ended September 30, 2014 compared to the three months ended September 30, 2013, due mainly to reduced average balances resulting from an increased allocation to TBA investments and, to a lesser extent, lower average yields. Interest income on non-agency RMBS increased by $0.5 million during the three months ended September 30, 2014 compared to the three months ended September 30, 2013, due to an increase in average balances, partially offset by lower average yields.

Interest income on agency RMBS decreased by $(52.9) million during the nine months ended September 30, 2014 compared to the nine months ended September 30, 2013, due mainly to reduced average balances resulting from an increased allocation to TBA investments and, to a lesser extent, lower average yields. Interest income on non-agency RMBS increased by $7.9 million during the nine months ended September 30, 2014 compared to the nine months ended September 30, 2013, due primarily to an increase in average balances, partially offset by lower average yields.

We amortize or accrete premiums and discounts associated with agency RMBS and non-agency RMBS of high credit quality into interest income over the life of such securities using the effective yield method. The effective yield (or asset yield) on these securities is based on actual CPRs realized for individual securities in our investment portfolio through the reporting

48

date and assumes a CPR over the remaining projected life of our aggregate investment portfolio. We estimate projected CPRs on these securities using a third-party service and market data. We update our estimates on at least a quarterly basis, and more frequently when economic or market conditions warrant. The effective yield on these securities is adjusted retrospectively for differences between actual and projected CPR estimates or for changes in our projected CPR estimates. Our projected CPR estimate for our agency RMBS was 8% and 7% as of September 30, 2014 and December 31, 2013, respectively. The actual CPR realized for individual agency RMBS in our investment portfolio was approximately 8.9% and 6.7% for the three months ended September 30, 2014 and 2013, respectively, and 7.7% and 6.8% for the nine months ended September 30, 2014 and 2013, respectively.

Interest income from our agency RMBS is net of premium amortization expense of $7.9 million and $12.8 million during the three months ended September 30, 2014 and 2013, respectively, and $26.6 million and $31.1 million for the nine months ended September 30, 2014 and 2013, respectively. The change in our weighted average CPR estimates resulted in the recognition of "catch up" premium amortization expense of approximately $(0.8) million during both the three months ended September 30, 2014 and 2013 and $(1.9) million and $4.4 million for the nine months ended September 30, 2014 and 2013, respectively. The amortized cost basis of our agency RMBS portfolio was 104.4% of par value as of both September 30, 2014 and December 31, 2013. The net unamortized premium balance of our aggregate agency RMBS portfolio was $182.0 million and $246.6 million, as of September 30, 2014 and December 31, 2013, respectively.

At the time we purchase non-agency RMBS 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. On at least a quarterly basis, we review the estimated cash flows and make appropriate adjustments with any changes in effective yield recognized prospectively based on the current amortized cost of the investment as adjusted for credit impairment, if any. Our estimates of future cash flows are based on input and analysis received from external sources, internal models and judgment about interest rates, prepayment rates, the timing and amount of credit losses and other factors. Interest income from our non-agency RMBS includes discount accretion of $10.2 million and $10.5 million during the three months ended September 30, 2014 and 2013, respectively, and $30.5 million and $25.4 million for the nine months ended September 30, 2014 and 2013, respectively. The weighted average cost basis of the non-agency portfolio was 67.9% and 60.7% of par as of September 30, 2014 and December 31, 2013, respectively. The total net discount remaining was $474.2 million and $599.8 million, with $146.3 million and $235.0 million designated as credit reserves as of September 30, 2014 and December 31, 2013, respectively.

Leverage

Our leverage, when adjusted for the net payables and receivables for unsettled securities and our net TBA position, was 4.9x and 5.1x our stockholders’ equity less investments in RCS and REIT equity securities as of September 30, 2014 and December 31, 2013, respectively. Our measurement of leverage excludes repurchase agreements used to fund short-term investments in U.S. Treasury securities due to the highly liquid and temporary nature of these investments. Our leverage will vary from time to time based on various factors, including our Manager’s opinion of the level of risk of our assets and liabilities, our view of the attractiveness of the return environment, composition of our investment portfolio, our liquidity position, our level of unused borrowing capacity, over-collateralization levels required by lenders when we pledge securities to secure our borrowings and the current market value of our investment portfolio. In addition, certain of our master repurchase agreements and master swap agreements contain a restriction that prohibits our leverage from exceeding certain levels. We do not expect these restrictions to adversely impact our operations.

The table below presents our quarterly average and quarter end repurchase agreement balances outstanding and average leverage ratios for the quarterly periods since September 30, 2013 (dollars in thousands):

	Repurchase Agreements (1)						Average Interest Rate as of Period End (1)		Average Leverage During the Period (2)	Leverage as of Period End (3)	Adjusted Leverage as of Period End (4)

⁽¹⁾ Excludes repurchase agreements collateralized by U.S. Treasury securities.

⁽²⁾  Average leverage for the period was calculated by dividing our daily weighted average agency and non-agency repurchase agreements by our average month-end stockholders’ equity for the period less investments in RCS and REIT equity securities.

49

⁽³⁾  Leverage as of period end was calculated by dividing the amount outstanding under our agency and non-agency repurchase agreements and net payables and receivables for unsettled agency and non-agency RMBS by our total stockholders’ equity at period end less our investments in RCS and REIT equity securities.

⁽⁴⁾  Adjusted leverage as of period end was calculated by dividing the sum of the amounts outstanding under our agency and non-agency repurchase agreements, the cost basis (or contract price) of our net TBA position and net payables and receivables for unsettled agency and non-agency RMBS by our total stockholders’ equity at period end less our investments in RCS and REIT equity securities.

Adjusted leverage included in the table above includes the impact of TBA positions, which have the effect of increasing or decreasing our "at risk" leverage. A net long position increases our at risk leverage, while a net short position reduces our at risk leverage. As of September 30, 2014, we had a net long TBA position with a notional value of $0.9 billion and an underlying cost basis of $1.0 billion.

Interest Expense and Cost of Funds

Interest expense of $6.4 million and $10.9 million for the three months ended September 30, 2014 and 2013, respectively, and $21.8 million and $28.1 million for the nine months ended September 30, 2014 and 2013, respectively, was comprised of interest expense on our repurchase agreements. We also incurred expense for our net periodic interest settlements related to our interest rate swaps of $5.2 million and $14.4 million for the three months ended September 30, 2014 and 2013, respectively, and $15.4 million and $32.2 million for the nine months ended September 30, 2014 and 2013, respectively, which is included in realized loss on periodic settlements of interest rate swaps, net, on our consolidated statements of operations.

⁽¹⁾   Variances that are the combined effect of volume and yield, but cannot be separately identified, are allocated to the volume and yield variances based on their respective relative amounts.

The $(13.8) million decrease in our adjusted cost of funds for the three months ended September 30, 2014 compared to the three months ended September 30, 2013 was attributable to a combination of lower average repurchase agreement balances and effective interest rate swap notional amounts and net pay rates, partially offset by an increase in repurchase agreement rates.

The $(23.1) million decrease in our adjusted cost of funds for the nine months ended September 30, 2014 compared to the nine months ended September 30, 2013 was attributable to a combination of lower average repurchase agreement balances and effective interest rate swap notional amounts and net pay rates, partially offset by an increase in repurchase agreement rates.

Net Servicing Loss

The following table presents the components of servicing income and expense for the three and nine months ended September 30, 2014 (dollars in thousands):

As of September 30, 2014, RCS managed a servicing portfolio of approximately 73,000 loans, representing approximately $15 billion in unpaid principal balances. RCS provides full end-to-end services for mortgage servicing solutions, including (i) loan acquisition and boarding, (ii) customer service, collections and loss mitigation, and (iii) foreclosure and real-estate owned services. We have elected to treat our investment in RCS as a TRS, and RCS is therefore subject to corporate income tax on its earnings.

Realized and Unrealized Gain (Loss) on Securities, Net

Sales of securities for the three and nine months ended September 30, 2014 were largely driven by a reduction in our on-balance sheet agency RMBS portfolio and a rebalancing of the agency and non-agency RMBS portfolios. These changes in portfolio composition were based upon our Manager's expectations concerning interest rates, Federal government programs, general economic conditions and other factors. During this period, we also increased our net long TBA position through TBA dollar roll transactions, a form of off-balance sheet financing.

The following table is a summary of our net realized gains and losses on agency RMBS during the three and nine months ended September 30, 2014 and 2013 (dollars in thousands):

Realized and unrealized net losses on interest rate swaps and swaptions of $(64.7) million and $(26.4) million, respectively, during the nine months ended September 30, 2014 were due mainly to the decrease in longer-term swap interest rates during the first half of 2014. Net unrealized gains of $13.4 million on interest rate swaps during the three months ended September 30, 2014 were due mainly to 5 year and shorter swap interest rates. Realized and unrealized net gains on TBA securities of $19.7 million during the nine months ended September 30, 2014 were due mainly to the significant increase in 30-year and 15-year fixed rate agency pricing during the first half of 2014. For further details regarding our derivatives and related hedging activity please refer to Notes 3 and 7 to our consolidated financial statements in this Quarterly Report on Form 10-Q.

Management Fees and General and Administrative Expenses

We pay our Manager a base management fee payable monthly in arrears in an amount equal to one twelfth of 1.50% of our equity. Our equity is defined as our month-end GAAP stockholders’ equity, adjusted to exclude the effect of any unrealized gains or losses included in retained earnings as computed in accordance with GAAP. There is no incentive compensation payable to our Manager pursuant to the management agreement. We incurred management fees of $4.5 million and $4.7 million during the three months ended September 30, 2014 and 2013, respectively, and $13.2 million and $14.2 million during the nine months ended September 30, 2014 and 2013, respectively. The period-over-period decreases were primarily a function of our share repurchases and net realized losses on agency RMBS during the second half of 2013.

General and administrative expenses were $1.9 million and $1.8 million during the three months ended September 30, 2014 and 2013, respectively, and $5.6 million and $5.5 million during the nine months ended September 30, 2014 and 2013, respectively. Our general and administrative expenses primarily consist of prime brokerage fees, information technology costs, research and data service fees, audit fees, Board of Directors fees and insurance expenses.

53

Our management fees and general and administrative expenses as a percentage of our average stockholders’ equity on an annualized basis were 2.1% for both the three months ended September 30, 2014 and 2013, and 2.2% and 2.1% for the nine months ended September 30, 2014 and 2013, respectively.

Dividends and Income Taxes

We had estimated taxable income of $19.6 million and $46.5 million (or $0.38 and $0.85 per common share) for the three months ended September 30, 2014 and 2013, respectively, and $73.6 million and $128.4 million (or $1.44 and $2.41 per common share) for the nine months ended September 30, 2014 and 2013, respectively.

As a REIT, we are required to distribute annually at least 90% of our taxable income to maintain our status as a REIT and all of our taxable income to avoid Federal and state corporate income taxes. We can treat dividends declared by September 15 and paid by December 31 as having been a distribution of our taxable income for our prior tax year ("spill-back provision"). 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 associated with assets and liabilities marked-to-market in current income for GAAP purposes, but excluded from taxable income until realized or settled, (ii) timing differences in the recognition of certain realized gains and losses, (iii) losses or undistributed income of taxable REIT subsidiaries and (iv) temporary differences related to the amortization of net premiums paid 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.

⁽¹⁾   Our estimated taxable income for the three and nine months ended September 30, 2014 excludes $0.73 per common share and $1.02 per common share, respectively, of estimated net capital gains in excess of capital losses, which are not included in our ordinary taxable income but are applied against previously recognized net capital losses, as well as $0.03 per common share and $0.40 per common share, respectively, of gains on terminated or expired swaptions and swaps, which for income tax purposes are deferred and amortized into future ordinary taxable income over the remaining terms of the underlying swaps.

The decrease in our estimated taxable income per common share is primarily a function of lower taxable net gains on investments and hedging instruments and lower net spread income.

We believe that the above non-GAAP financial measures provide information useful to investors because estimated taxable income has an impact on the amount of dividends we are required to distribute over time in order to maintain our REIT tax qualification status.

We also believe that providing investors with estimated taxable income and certain financial metrics derived from such non-GAAP financial information, in addition to the related GAAP measures, gives investors greater transparency to the information used by management in its financial and operational decision-making. However, because estimated taxable income is an incomplete measure of our financial performance and involves differences from net income computed in accordance with GAAP, this non-GAAP financial information should be considered supplementary to, and not a substitute for, our net income computed in accordance with GAAP as a measure of our financial performance. In addition, because not all companies use identical calculations, our presentation of estimated taxable income may not be comparable to other similarly-titled measures of

55

other companies. Furthermore, estimated taxable income can include certain information that is subject to potential adjustments up to the time of filing our income tax returns, which occurs after the end of our fiscal year.

We declared dividends of $0.65 and $0.70 per common share for the three months ended September 30, 2014 and 2013, respectively, and $1.95 and $2.40 per common share for the nine months ended September 30, 2014 and 2013, respectively.

As of September 30, 2014, we had an estimated $13.3 million (or $0.26 per common share) of undistributed taxable income, net of the dividend payable as of September 30, 2014 of $34.4 million. We have distributed all of our remaining 2013 taxable income within the allowable time frame, including the available spill-back provision, so that we will not be subject to Federal or state corporate income tax. However, as a REIT, we are still subject to a nondeductible Federal excise tax of 4% to the extent that the sum of (i) 85% of our ordinary taxable income, (ii) 95% of our capital gains and (iii) any undistributed taxable income from the prior year, exceeds our dividends declared in such year and paid by January 31 of the subsequent year. We recorded estimated excise tax of $0.4 million for both the nine months ended September 30, 2014 and 2013.

We acquired 100% of RCS, which is taxable as a corporation under Subchapter C of the Internal Revenue Code, on November 27, 2013, with which we filed a joint TRS election. As of September 30, 2014, RCS had Federal net operating loss ("NOL") carryforwards of approximately $58.0 million which can be carried forward for up to twenty years. As a result of the change in ownership, the utilization of most of the NOL is subject to limitations imposed by the Internal Revenue Code. The gross deferred tax assets associated with the NOL and other temporary differences as of September 30, 2014 were approximately $28.0 million, with respect to which RCS has provided a full valuation allowance.

⁽¹⁾  Weighted average cost of funds includes periodic settlements of interest rate swaps.

⁽²⁾  Estimated dollar roll income is net of short TBAs used for hedging purposes. Dollar roll income excludes the impact of other supplemental hedges, and is recognized in gain (loss) on derivative instruments and other securities, net.

⁽³⁾  Leverage during the period was calculated by dividing the Company's daily weighted average agency and non-agency repurchase agreements for the period by the Company's average month-ended stockholders' equity for the period less investments in RCS and REIT equity securities. Leverage excludes U.S. Treasury repurchase agreements.

⁽⁴⁾  Leverage at period end was calculated by dividing the sum of the amount outstanding under the Company's agency and non-agency repurchase agreements and the net receivable/payable for unsettled securities at period end by the Company's stockholders' equity at period end less investments in RCS and REIT equity securities. Leverage excludes U.S. Treasury repurchase agreements.

—————— 

⁽¹⁾   Dividend income from investments in REIT equity securities is included in realized gain on other derivatives and securities, net on the consolidated statements of operations.

Net spread and dollar roll income per common share increased $0.10 during the three months ended September 30, 2014 compared to the three months ended September 30, 2013 due primarily to lower swap hedge ratios and net pay rates. Net spread and dollar roll income per common share decreased $0.42 for the nine months ended September 30, 2014 compared to the nine months ended September 30, 2013 due primarily to a reduction in leverage, including our net TBA position.

We believe that the above non-GAAP financial measures provide information useful to investors because net spread and dollar roll income is a financial metric used by management and investors and estimated taxable income is directly related to the amount of dividends we are required to distribute in order to maintain its REIT tax qualification status.

We also believe that providing investors with our net spread and dollar roll income, estimated taxable income and certain financial metrics derived from such non-GAAP financial information, in addition to the related GAAP measures, gives investors greater transparency to the information used by management in its financial and operational decision-making and that it is meaningful information to consider related to the economic costs of financing our investment portfolio inclusive of interest rate swaps used to economically hedge against fluctuations in our borrowing costs, without the effects of certain transactions that are not necessarily indicative of our current investment portfolio and operations.

However, because such non-GAAP financial information provides incomplete measures of our financial performance and involve differences from results computed in accordance with GAAP, they should be considered supplementary to, and not a substitute for, our 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-titled measures of other companies.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of funds are borrowings under master repurchase agreements, equity offerings, asset sales and monthly principal and interest payments on our investment portfolio. Because the level of our borrowings can be adjusted on a daily basis, the level of cash and cash equivalents carried on our balance sheets is significantly less important than the potential liquidity available under our borrowing arrangements. We currently believe that we have sufficient liquidity and capital resources available for 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. To qualify as a REIT, we must distribute annually at least 90% of our taxable income. To the extent that we annually distribute all of our taxable income in a timely manner, we will generally not be subject to Federal and state income taxes. We currently expect to distribute all of our taxable income in a timely manner so that we are not subject to Federal and state income taxes. This distribution requirement limits our ability to retain earnings and thereby replenish or increase capital from operations.

Equity Capital

To the extent we raise additional equity capital through follow-on equity offerings, we currently anticipate using cash proceeds from such transactions to purchase additional investment securities, to make scheduled payments of principal and interest on our repurchase agreements and for other general corporate purposes. There can be no assurance, however, that we will be able to raise additional equity capital at any particular time or on any particular terms. In addition, during the nine months ended September 30, 2014, we repurchased approximately $4.2 million of our stock under our stock repurchase program as our stock was trading at a meaningful discount to our estimated net asset value per common share.

Stock Repurchase Program

In October 2012, our Board of Directors adopted a program that provided for repurchases of up to $50 million of our outstanding shares of common stock through December 31, 2013. In June 2013, our Board of Directors authorized the repurchase of up to an additional $100 million of our outstanding shares of common stock through December 31, 2013. In September 2013, our Board of Directors authorized the repurchase of up to an additional $150 million of our outstanding shares of common stock and extended its authorization through December 31, 2014. In October 2014, our Board of Directors extended the Company's existing stock repurchase program through December 31, 2015. Shares may be purchased in the open market, including through block purchases, or through privately negotiated transactions, or pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended.  The timing, manner, price and amount of any repurchases will be determined at our discretion and the program may be suspended, terminated or modified at any time for any reason.  We intend to repurchase shares only when the purchase price is less than our estimate of our current net asset value per common share. Generally, when we repurchase our common stock at a discount to our net asset value, the net asset value of our remaining shares outstanding increases. In addition, we do not intend to repurchase any shares from directors, officers or other affiliates. The program does not obligate us to acquire any specific number of shares, and all repurchases will be made in accordance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, which sets certain restrictions on the method, timing, price and volume of stock repurchases.

We did not repurchase any shares of our common stock during the three months ended September 30, 2014. During the nine months ended September 30, 2014, we repurchased approximately 0.2 million shares of our common stock at an average repurchase price of $19.67 per share, including expenses, totaling $4.2 million. As of September 30, 2014, we had an additional $134.9 million available for repurchases of our common stock through December 31, 2015, as authorized by the Board of Directors.

Dividend Reinvestment and Direct Stock Purchase Plan

We sponsor a dividend reinvestment and direct stock purchase plan through which stockholders may purchase additional shares of our common stock by reinvesting some or all of the cash dividends received on shares of our common stock. Stockholders may also make optional cash purchases of shares of our common stock subject to certain limitations detailed in the plan prospectus. We did not issue any shares under the plan during the three and nine months ended September 30, 2014.

Debt Capital

As part of our investment strategy, we borrow against our agency and non-agency RMBS pursuant to master repurchase agreements. We expect that our borrowings pursuant to repurchase transactions under such master repurchase agreements generally will have maturities of less than one year. When adjusted for net payables and receivables for unsettled agency and non-agency RMBS, our leverage ratio was 4.1x and 5.9x the amount of our stockholders’ equity less our investments in RCS and REIT equity securities as of September 30, 2014 and December 31, 2013, respectively, excluding amounts borrowed under

59

U.S. Treasury repurchase agreements. Our cost of borrowings under master repurchase agreements generally corresponds to LIBOR plus or minus a margin.

To limit our exposure to counterparty credit risk, we diversify our funding across multiple counterparties and by counterparty region. We had repurchase agreements with 33 financial institutions as of September 30, 2014, located throughout North America, Europe and Asia. In addition, less than 5% of our equity was at risk with any one repurchase agreement counterparty, with the top five counterparties representing less than 18% of our equity at risk as of September 30, 2014.

As of September 30, 2014, borrowings of $3.8 billion and $0.6 billion, with weighted average remaining days to maturity of 99 days and 22 days, were secured by agency and non-agency RMBS, respectively.

The table below includes a summary of our repurchase agreement funding and number of counterparties by region as of September 30, 2014. Refer to Note 6 to our consolidated financial statements in this Quarterly Report on Form 10-Q for further details regarding our borrowings under repurchase agreements and weighted average interest rates as of September 30, 2014.

Amounts available to be borrowed under our repurchase agreements are dependent upon lender collateral requirements and the lender's determination of the fair value of the securities pledged as collateral, based on recognized pricing sources agreed to by both parties to the agreement. Collateral fair value can fluctuate with changes in interest rates, credit quality and liquidity conditions within the investment banking, mortgage finance and real estate industries. Our counterparties also apply a "haircut" to the fair value of our pledged collateral, which reflects the underlying risk of the specific collateral and protects our counterparties against a decrease in collateral value, but conversely subjects us to counterparty 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 three months ended September 30, 2014, haircuts on our pledged collateral remained stable and as of September 30, 2014, our weighted average haircut on agency and non-agency RMBS held as collateral were approximately 5% and 26%, respectively.

Under our repurchase agreements, we may be required to pledge additional assets to repurchase agreement counterparties in the event the estimated fair value of the existing pledged collateral under such agreements declines and such 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 value of our securities securing our repurchase agreements and 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 for the securities securing our repurchase agreements are to be obtained from a generally recognized source agreed to by the parties. However, in certain circumstances and under certain of our repurchase agreements, our lenders have the sole discretion to determine the value of the securities securing our repurchase agreements. 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, 2014, we had met all margin requirements and had unrestricted cash and cash equivalents of $204.9 million and unpledged securities of approximately $340.4 million, excluding unsettled purchases of securities, available to meet margin calls on our repurchase agreements and derivative instruments as of September 30, 2014.

Although we believe that 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 securities back to us at the end of the term, we could incur a loss equal to the difference between the value of the securities and the cash we originally received.

60

We maintain an interest rate risk management strategy under which we use derivative financial instruments to help manage the adverse impact of interest rates changes on the value of our investment portfolio as well as our cash flows. In particular, we attempt to mitigate the risk of the cost of our short-term variable rate liabilities increasing at a faster rate than the earnings of our long-term assets during a period of rising interest rates. The principal derivative instruments that we use are interest rate swaps, swaptions and short Treasury positions. We may also supplement our hedge portfolio with the use of TBA positions and other instruments.

Refer to Notes 3 and 7 to our consolidated financial statements in this Quarterly Report on Form 10-Q for further details regarding our outstanding interest rate swaps as of September 30, 2014 and the related activity for the three months ended September 30, 2014.

Our derivative agreements typically require that we pledge/receive collateral on such agreements to/from our counterparties in a similar manner as we are required to under our repurchase agreements. Our counterparties, or the clearing exchange in the case of our centrally cleared interest rate swaps, typically have the sole discretion to determine the value of the derivative instruments and the value of the collateral securing such instruments. In the event of a margin call, we must generally provide additional collateral on the same business day.

Similar to repurchase agreements, our use of derivatives exposes us to counterparty credit risk relating to potential losses

that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. We minimize this risk by limiting our counterparties to major financial institutions with acceptable credit ratings, by maintaining collateral sufficient to cover the change in market value, and by monitoring positions with individual counterparties.

We did not have an amount at risk with any counterparty related to our non-centrally cleared interest rate swap and swaption agreements greater than 1% of our stockholders’ equity, as of September 30, 2014.

In the case of centrally cleared interest rate swap contracts, 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, the risk is considered minimal due to initial and daily exchange of mark to market margin requirements and the clearinghouse guarantee fund and other resources that are available in the event of a clearing member default.

TBA Dollar Roll Transactions

We also enter into TBA dollar roll transactions as a means of leveraging (long TBAs) or de-leveraging (short TBAs) our investment portfolio. TBA dollar roll transactions represent a form of off-balance sheet financing and are accounted for as derivative instruments in our accompanying consolidated financial statements in this Quarterly Report on Form 10-Q. Inclusive of our net TBA position as of September 30, 2014, our total "at risk" leverage, net of unsettled securities, was 4.9x our stockholders' equity.

Under certain market conditions, it may be uneconomical for us to roll our TBA contracts into future months and we may need to take or make physical delivery of the underlying securities. If we were required to take physical delivery of a long TBA contract, we would have to fund the total purchase commitment with cash or other financing sources and our liquidity position could be negatively impacted. However, as of September 30, 2014, we had a net long TBA position with a cost basis and fair value of the securities underlying our net long TBA position each totaling $0.9 billion.

Our TBA dollar roll contracts are also subject to margin requirements governed by the Mortgage-Backed Securities Division ("MBSD") of the Fixed Income Clearing Corporation and by our prime brokerage agreements, 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 is subject to increase if the estimated fair value of our TBA contract or the estimated fair value of our pledged collateral declines. The MBSD has the sole discretion to determine the value of our TBA contracts and of the collateral pledged securing such contracts. In the event of a margin call, we must generally provide additional collateral on the same business day.

Settlement of our net long TBA obligations by taking delivery of the underlying securities as well as satisfying margin requirements could negatively impact our liquidity position. However, since we do not use TBA dollar roll transactions as our primary source of financing, we believe that we will have adequate sources of liquidity to meet such obligations.

61

Asset Sales and TBA Eligible Securities

We maintain a portfolio of highly liquid agency RMBS. We may sell our agency RMBS through the TBA market by delivering securities into TBA contracts for the sale of securities, subject to "good delivery" provisions promulgated by the Securities Industry and Financial Markets Association ("SIFMA"). We may alternatively sell agency RMBS 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 agency TBA market is the second most liquid market (second to the U.S. Treasury market), maintaining a significant level of agency RMBS eligible for TBA delivery enhances our liquidity profile and provides price support for our TBA eligible securities in a rising interest rate scenario at or above generic TBA prices. As of September 30, 2014, approximately 86% of our agency RMBS portfolio was eligible for TBA delivery.

OFF-BALANCE SHEET ARRANGEMENTS

As of September 30, 2014, we did not maintain any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance, or special purpose or variable interest entities, established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Further, as of September 30, 2014, we had not guaranteed any obligations of unconsolidated entities or entered into any commitment or intent to provide funding to any such entities.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the exposure to loss resulting from changes in market factors such as interest rates, foreign currency exchange rates, commodity prices and equity prices. The primary market risks that we are exposed to are interest rate risk, prepayment risk, spread risk, liquidity risk, extension risk credit risk, and inflation risk.

Interest Rate Risk

Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond our control.

Changes in the general level of interest rates can affect 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. Changes in the level of interest rates can also affect the rate of prepayments of our securities and the value of the RMBS that constitute our investment portfolio, which affects our net income and ability to realize gains from the sale of these assets and impacts our ability and the amount that we can borrow against these securities.

We may utilize a variety of financial instruments in order to limit the effects of changes in interest rates on our operations. The principal instruments that we use are interest rate swaps and options to enter into interest rate swaps. We also utilize forward contracts for the purchase or sale of agency RMBS on a generic pool, or a TBA contract basis and on a non-generic, specified pool basis, and we utilize U.S. Treasury securities and U.S. Treasury futures contracts, primarily through short sales. We may also purchase or write put or call options on TBA securities and we may invest in other types of mortgage derivatives, such as interest and principal-only securities, and synthetic total return swaps. Derivative instruments may expose us to certain

62

risks, including the risk that losses on a hedge position will reduce the funds available for payments to holders of our common stock and that the losses may exceed the amount we invested in the instruments.

Our profitability and the value of our investment portfolio (including derivatives used for hedging purposes) may be adversely affected during any period as a result of changing interest rates including changes in forward yield curves.

Primary measures of an instrument's price sensitivity to interest rate fluctuations are its duration and convexity. The duration of our investment portfolio changes with interest rates and tends to increase when interest rates rise and decrease when rates fall. The "negative convexity" generally increases the interest rate exposure of our investment portfolio by more than what is measured by duration alone.

We estimate the duration and convexity of our portfolio using both a third-party risk management system and market data. We review the duration estimates from the third-party model and may make adjustments based on our Manager's judgment. These adjustments are intended to, in our Manager's opinion, better reflect the unique characteristics and market trading conventions associated with certain types of securities, such as HARP and lower loan balance securities. These adjustments generally result in shorter durations than what the unadjusted third party model would otherwise produce. Without these adjustments, in rising rate scenarios, the longer unadjusted durations may underestimate price projections on certain securities with slower prepayment characteristics, such as HARP and lower loan balance securities, to a level below those of generic or TBA securities. However, in our Manager's judgment, because these securities are typically deliverable into TBA contracts, the price of these securities is unlikely to drop below the generic or TBA price in rising rate scenarios. The accuracy of the estimated duration of our portfolio and projected agency security prices depends on our Manager's assumptions and judgments. Our Manager may discontinue making these duration adjustments in the future or may choose to make different adjustments. Other models could produce materially different results.

Further, since we do not control the other mortgage REITs that we invest in, we have limited transparency into their underlying investment and hedge portfolios. Therefore, our Manager must make certain assumptions to estimate the duration and convexity of the underlying portfolios and their sensitivity to changes in interest rates. Such estimates do not include the potential impact of other factors which may affect the fair value of our investments in other mortgage REITs, such as stock market volatility. Accordingly, actual results could differ from our estimates.

The table below quantifies the estimated changes in net interest income (including periodic interest costs on our interest rate swaps) and the estimated changes in the fair value of our investment portfolio (including derivatives and other securities used for hedging purposes) and in our net asset value should interest rates go up or down by 50 and 100 basis points, assuming instantaneous parallel shifts in the yield curve, and including the impact of both duration and convexity.

All changes in income and value are measured as percentage changes from the projected net interest income, investment

portfolio value and net asset value at the base interest rate scenario. The base interest rate scenario assumes interest rates and prepayment projections as of September 30, 2014 and December 31, 2013. 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.

Actual results could differ materially from estimates, especially in the current market environment. To the extent that these estimates or other assumptions do not hold true, which is likely in a period of high price volatility, actual results will likely differ materially from projections and could be larger or smaller than the estimates in the table below. Moreover, if different models were employed in the analysis, materially different projections could result. Lastly, while the table below reflects the estimated impact of interest rate increases and decreases on a static portfolio, we may from time to time sell any of our agency or non-agency RMBS as a part of our overall management of our investment portfolio.

The change in our interest rate sensitivity as of September 30, 2014 compared to December 31, 2013 was a function of a flatter yield curve, partially mitigated by changes in the size and composition of our asset and hedge portfolio.

Prepayment Risk

Because residential borrowers have the option to prepay their mortgage loans at par at any time, we face the risk that we

will experience a return of principal on our investments faster than anticipated. Various factors affect the rate at which mortgage prepayments occur, including changes in the level of and directional trends in housing prices, interest rates, general economic conditions, loan age and size, loan-to-value ratio, the location 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 the loans underlying our securities become seriously delinquent or are modified and the timing of GSE repurchases of such loans from our securities can materially impact the rate of prepayments. Generally, prepayments on agency RMBS increase during periods of falling mortgage interest rates and decrease during periods of rising mortgage interest rates. However, this may not always be the case.

We may reinvest principal repayments at a yield that is lower or higher than the yield on the repaid investment, thus affecting our net interest income by altering the average yield on our assets. Premiums or discounts associated with the purchase of agency RMBS and non-agency RMBS of higher credit quality are amortized or accreted into interest income over the 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 prepayment experienced differs from our estimate of prepayments, we will be required to make an adjustment to the amortization or accretion of premiums and discounts that would have an impact on future income.

Spread Risk

When the market spread between the yield on our RMBS and benchmark interest rates widens, our net book value could decline if the value of our RMBS falls by more than the offsetting fair value increases on our hedging instruments, creating what we refer to as "spread risk" or "basis risk". The spread risk associated with our agency and non-agency RMBS and the resulting fluctuations in fair value of these securities can occur independent of changes in benchmark interest rates and may

64

relate to other factors impacting the mortgage and fixed income markets, such as actual or anticipated monetary policy actions by the Fed, 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 will not protect our net book value against spread risk.

The table below quantifies the estimated changes in the fair value of our investment portfolio (including derivatives and other securities used for hedging purposes) and in our net asset value should spreads between our mortgage assets and benchmark interest rates go up or down by 10 and 25 basis points. These estimated impacts of spread changes are in addition to our sensitivity to interest rate shocks included in the above interest rate sensitivity table. The table below assumes a spread duration of 5.5 years based on interest rates and RMBS prices as of both September 30, 2014 and December 31, 2013. However, our portfolio's sensitivity of mortgage spread changes will vary with changes in interest rates and will generally increase as interest rates rise and prepayments slow. Additionally, we have limited transparency into the underlying investment and hedge portfolios of the other agency mortgage REITs in which we invest.

Liquidity Risk

The primary liquidity risk for us arises from financing long-term assets with shorter-term borrowings through repurchase agreements. Our assets that are pledged to secure repurchase agreements are agency and non-agency RMBS and cash. As of September 30, 2014, we had unrestricted cash and cash equivalents of $204.9 million and unpledged securities of approximately $340.4 million, excluding unsettled purchases of securities, available to meet margin calls on our repurchase agreements, derivative instruments and for other corporate purposes. However, should the value of our securities pledged as collateral or the value of our derivative instruments suddenly decrease, margin calls relating to our repurchase and derivative agreements could increase, causing an adverse change in our liquidity position. Further, there is no assurance that we will always be able to renew (or roll) our repurchase agreements. In addition, our counterparties have the option to increase our haircuts (margin requirements) on the assets we pledge, thereby reducing the amount that can be borrowed against an asset even if they agree to renew or roll the repurchase agreement. Significantly higher haircuts can reduce our ability to leverage our portfolio or even force us to sell assets, especially if correlated with asset price declines or faster prepayment rates on our assets.

In addition, we may utilize TBA dollar roll transactions as a means of acquiring and financing purchases of agency RMBS. Under certain economic conditions we may be unable to roll our TBA dollar roll transactions prior to the settlement date and we may 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.

65

Extension Risk

The projected weighted-average life and the duration (or interest rate sensitivity) of our investments is based on our Manager’s assumptions regarding the rates at which borrowers will prepay or default on the underlying mortgage loans. In general, we use interest rate swaps to help manage our funding cost on our investments in the event that interest rates rise. These swaps 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 repurchase agreements.

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 securities collateralized by fixed rate mortgages to decline by more than otherwise would be the case while most of our hedging instruments (with the exception of short TBA mortgage positions, interest-only securities and certain other supplemental 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

We are exposed to credit risk related to our non-agency investments, certain derivative transactions, and our collateral held by funding and derivative counterparties. We accept credit exposure at levels we deem prudent as an integral part of our diversified investment strategy. Therefore, we may retain all or a portion of the credit risk on our non-agency investments. We seek to manage this risk through prudent asset selection, pre-acquisition due diligence, post-acquisition performance monitoring, sale of assets where we have identified negative credit trends and the use of various types of credit enhancements. We may also use non-recourse financing, which limits our exposure to credit losses to the specific pool of mortgages subject to the non-recourse financing. Our overall management of credit exposure may also include the use of credit default swaps or other financial derivatives that we believe are appropriate. Additionally, we intend to vary the percentage mix of our non-agency mortgage investments and agency mortgage investments in an effort to actively adjust our credit exposure and to improve the risk/return profile of our investment portfolio. Our credit risk related to certain derivative transactions is largely mitigated through daily adjustments to collateral pledged based on changes in market value and we limit our counterparties to major financial institutions with acceptable credit ratings. There is no guarantee that our efforts to manage credit risk will be successful and we could suffer significant losses if credit performance is worse than our expectations or if economic conditions worsen.

Inflation Risk

Virtually all of our assets and liabilities are interest rate sensitive in nature. As a result, interest rates and other factors influence our performance more so than does inflation. Changes in interest rates do not necessarily correlate with inflation rates or changes in inflation rates. Further, our consolidated financial statements are prepared in accordance with GAAP and our distributions are determined by our Board of Directors based primarily on our net income as calculated for income tax purposes. In each case, our activities and consolidated balance sheets are measured with reference to historical cost and/or fair market value without considering inflation.

Item 4.Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act of 1934, as amended (the "Exchange Act") reports is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of "disclosure controls and procedures" as promulgated under the Exchange Act and the rules and regulations thereunder. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of September 30, 2014. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective.

66

Changes in Internal Control over Financial Reporting

There have been no changes in our "internal control over financial reporting" (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during our fiscal quarter ended September 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be involved in various claims and legal actions arising in the ordinary course of business. Neither we, nor any of our consolidated subsidiaries, are currently subject to any material litigation, nor to our knowledge, is any material litigation threatened against us or any consolidated subsidiary.

Item 1A.Risk Factors

There have been no material changes to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2013, except as described below.

You should carefully consider the risks described below and all other information contained in this interim report on Form

10-Q, including our interim consolidated financial statements and the related notes thereto before making a decision to purchase

our securities. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not

presently known to us, or not presently deemed material by us, may also impair our operations and performance. If any of the following risks actually occur, our business, financial condition or results of operations could be materially adversely affected. If that happens, the trading price of our securities could decline, and you may lose all or part of your investment.

We may be subject to representation and warranty risk and counterparty exposure risk in connection with our acquisition of MSR and this risk could adversely impact our financial performance.

When engaging in MSR acquisitions, we typically acquire MSR subject to existing representations and warranties made to the applicable investor (including, without limitation, the GSEs) regarding, among other things, the origination and prior servicing of those mortgage loans, as well as future servicing practices following our acquisition of such MSR. If such representations and warranties are inaccurate, we may be obligated to repurchase certain mortgage loans, which may result in a loss, or indemnify the applicable investor for any losses suffered as a result of the origination or prior servicing of the mortgage loans. As such, the applicable investor will have direct recourse to us for such origination and / or prior servicing issues. Even if we obtain representations and warranties from the loan originator or other parties from whom we acquired the MSR, they may not correspond with the representations and warranties we make or may otherwise not protect us from losses. For example, if representations and warranties we obtain from those parties do not exactly align with the representations and warranties we make, or if the representations and warranties made to us are not enforceable or if we cannot collect damages for a breach (e.g., due to the financial condition of the party that made the representation or warranty to us), we may incur losses that could adversely impact our financial performance.

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Fair Value of Financial Assets

We have elected the option to account for all of our financial assets, including all mortgage-related investments, at estimated fair value, with changes in fair value reflected in income during the period in which they occur. In management's view, this election more appropriately reflects the results of our operations for a particular reporting period, as financial asset fair value changes are presented in a manner consistent with the presentation and timing of the fair value changes of hedging instruments. See Note 9 - Fair Value Measurements.

Interest Income

Interest income is accrued based on the outstanding principal amount of the securities and their contractual terms. Premiums or discounts associated with the purchase of agency RMBS and non-agency RMBS 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.

We estimate long-term prepayment speeds using a third-party service and market data. The third-party service estimates prepayment speeds for our securities using models that incorporate the mortgage rates, age, size and loan-to-value ratios of the outstanding underlying loans, as well as current mortgage rates, forward yield curves, volatility and other factors. We review the prepayment speeds estimated by the third-party service and compare the results to market consensus prepayment speeds, if available. We also consider historical prepayment speeds and current market conditions to validate the reasonableness of the prepayment speeds estimated by the third-party service, and based on our Manager’s judgment, we may make adjustments to its estimates. Actual and anticipated prepayment experience is reviewed at least quarterly and effective yields are recalculated when differences arise between the previously estimated future prepayments and the amounts actually received plus currently anticipated future prepayments. If the actual and anticipated future prepayment experience differs from our prior estimate of prepayments, we are required to record an adjustment in the current period to the amortization or accretion of premiums and discounts for the cumulative difference in the effective yield through the reporting date.

At the time we purchase non-agency RMBS and loans 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 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 input and analysis received from external sources, internal models, and our judgment about interest rates, prepayment rates, the timing and amount of credit losses, 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, if any.

Mortgage Servicing Rights, at Fair Value

Our MSR represent the right to service mortgage loans for a servicing fee. MSR are reported at fair value on our consolidated balance sheets, with changes in fair value related to changes in valuation inputs and assumptions reported as unrealized loss on MSR on the consolidated statements of operations. Servicing fees, incentive fees and ancillary income are reported within servicing income on the consolidated statements of operations. The related servicing expenses and realization of cash flows related to underlying loan repayments, net of recoveries of contractual prepayment protection, are recorded in servicing expenses on the consolidated statements of operations. See Note 10 - Mortgage Servicing Rights for further discussion on MSR.

The accounting model used to evaluate whether a transfer of MSR qualifies as a sale is based on a risks and rewards approach, as MSR are not financial assets. In certain cases where we transfer the economics of MSR while retaining the actual servicing function, we retain the risk associated with servicing and, as a result, the transfer does not qualify for sale accounting. As such, we retain the MSR, together with an offsetting financing liability on our consolidated balance sheets. We have elected the option to account for MSR financing liabilities at estimated fair value, with changes in fair value reflected in income during the period in which they occur. See Note 12 - Accounts Payable and Other Accrued Liabilities for the presentations of our mortgage servicing liability.

We may be obligated to fund advances of principal and interest payments due to third party owners of the loans but not yet received from the individual borrowers. We may also be obligated to fund advances of real estate taxes and insurance, protective advances to preserve the value of the underlying property, and expenses associated with remedial action in respect of defaulted loans. These servicing advances are reported within other assets on the consolidated balance sheets.

REIT Equity Securities, at Fair Value

REIT equity securities represent investments in the common stock of other publicly traded mortgage REITs that invest predominately in agency RMBS. We designate our investments in REIT equity securities as trading securities and report them at fair value on the accompanying consolidated balance sheets with changes in fair value recorded in unrealized gain (loss) on other derivatives and securities, net on the accompanying consolidated statements of operations. Dividend income from REIT equity securities is recorded in realized gain on other derivatives and securities, net.

Repurchase Agreements

We finance the acquisition of agency RMBS and certain non-agency RMBS for our investment portfolio through repurchase transactions under master repurchase agreements. We account for repurchase transactions as collateralized financing transactions which are carried at their contractual amounts, including accrued interest, as specified in the respective transaction agreements. The contractual amounts approximate fair value due to their short-term nature.

Reverse Repurchase Agreements and Obligation to Return Securities Borrowed under Reverse Repurchase Agreements

From time to time we borrow securities to cover short sales of U.S. Treasury securities through reverse repurchase transactions under our master repurchase agreements (see Derivatives below). We account for these as securities borrowing transactions and recognize an obligation to return the borrowed securities at fair value on the consolidated balance sheets based on the value of the underlying borrowed securities as of the reporting date. Our reverse repurchase agreements generally mature daily. The fair value of our reverse repurchase agreements is assumed to equal cost as the interest rates are reset daily.

Derivatives

We utilize a risk management strategy, under which we may use a variety of derivative instruments to hedge some of our exposure to market risks, including interest rate risk, prepayment risk, extension risk and credit risk. The objective of our risk management strategy is to reduce fluctuations in net book value over a range of market conditions. The principal instruments that we currently use are interest rate swaps and options to enter into interest rate swaps ("interest rate swaptions"). We also utilize forward contracts for the purchase or sale of agency RMBS, or to-be-announced forward ("TBA") contracts, and short sales of U.S. Treasury securities and U.S. Treasury futures contracts. We may also purchase or write put or call options on TBA securities and we may invest in other types of mortgage derivatives, such as synthetic total return swaps.

We also enter into TBA contracts as a means of investing in and financing agency RMBS (thereby increasing our "at

risk" leverage) or as a means of disposing of or reducing our exposure to agency RMBS (thereby reducing our "at risk" leverage). Pursuant to TBA contracts, we agree to purchase or sell, for future delivery, agency RMBS with certain principal and interest terms and certain types of collateral, but the particular agency RMBS to be delivered are not identified until shortly before the TBA settlement date. We may also choose, prior to settlement, to move the settlement of these securities out to a later date by entering into an offsetting short or long position (referred to as a "pair off"), net settling the paired off positions for cash, and simultaneously purchasing or selling a similar TBA contract for a later settlement date. This transaction is commonly referred to as a "dollar roll." The agency RMBS purchased or sold for a forward settlement date are typically priced at a discount to agency RMBS for settlement in the current month. This difference (or discount) is referred to as the "price drop." The price drop is the economic equivalent of net interest carry income on the underlying agency RMBS over the roll period (interest income less implied financing cost) and is commonly referred to as "dollar roll income (loss)." Consequently, forward purchases of agency RMBS and dollar roll transactions represent a form of off-balance sheet financing.

We recognize all derivative instruments as either assets or liabilities on the balance sheets, measured at fair value. As we have not designated any derivatives as hedging instruments, all changes in fair value are reported in earnings in our consolidated statements of operations in unrealized gain (loss) on other derivatives and securities, net during the period in which they occur. Derivatives in a gain position are reported as derivative assets at fair value and derivatives in a loss position are reported as derivative liabilities at fair value in our consolidated balance sheets. Cash receipts and payments related to 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.

Our derivative agreements generally contain provisions that allow for netting or setting off derivative assets and liabilities with each counterparty; however, we report related assets and liabilities on a gross basis in our consolidated balance sheets.

The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. We attempt to minimize this risk by limiting our counterparties to major financial institutions with acceptable credit ratings, monitoring positions with individual counterparties and adjusting posted collateral as required.

Interest rate swap agreements

We use interest rate swaps to hedge the variable cash flows associated with short-term borrowings made under our repurchase agreement facilities. 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") with terms up to 15 years. The floating rate we receive under our swap agreements has the effect of offsetting the repricing characteristics of our repurchase agreements and cash flows on such liabilities. Our swap agreements are privately negotiated in the over-the-counter ("OTC") market and may be centrally cleared through a registered commodities exchange ("centrally cleared swaps").

We estimate the fair value of our centrally cleared interest rate swaps using the daily settlement price determined by the respective exchange. Centrally cleared swaps are valued by the exchange using a pricing model that references the underlying rates, including the overnight index swap rate and LIBOR forward rate, to produce the daily settlement price. We estimate the fair value of our "non-centrally cleared" swaps using a combination of inputs from counterparty and third-party pricing models to estimate the net present value of the future cash flows using a forward yield curve in effect as of the end of the measurement period. We also incorporate any of our own and our counterparties’ unmitigated nonperformance risk in estimating the fair value of our interest rate swaps. In considering the effect of nonperformance risk, we consider the impact of netting and credit enhancements, such as collateral postings and guarantees, and have concluded that our own and our counterparty credit risk is not significant to the overall valuation of these agreements.

The payment of periodic settlements of net interest on interest rate swaps is reported in realized loss on periodic settlements of interest rate swaps, net in our consolidated statements of operations. Cash payments received or paid for the early termination of an interest rate swap agreement are recorded as realized gain on other derivatives and securities, net in our consolidated statements of operations. Changes in fair value of our interest rate swap agreements are reported in unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations.

Interest rate swaptions

We purchase interest rate swaptions to help mitigate the potential impact of larger increases or decreases in interest rates

on the performance of our investment portfolio. The interest rate swaptions provide us the option to enter into an interest rate swap agreement for a predetermined notional amount, stated term and pay or receive interest rates in the future. The premium paid for interest rate swaptions is reported as a derivative asset in our consolidated balance sheets. We estimate the fair value of interest rate swaptions 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. The difference between the premium and the fair value of the swaption is reported in unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations. If a swaption expires unexercised, the realized loss on the swaption would be equal to the premium paid and reported in realized gain on other derivatives and securities, net in our consolidated statements of operations. If we exercise a swaption, the realized gain or loss on the swaption would be equal to the difference between the fair value of the underlying interest rate swap and the premium paid and reported in realized gain on other derivatives and securities, net in our consolidated statements of operations.

Interest rate swaption agreements are privately negotiated in the OTC market and are not subject to central clearing. 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.

TBA securities

A TBA security is a forward contract for the purchase ("long position") or sale ("short position") of agency RMBS at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific agency RMBS delivered into the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association, are not known at the time of the transaction. We may enter into TBA contracts as a means of hedging against short-term changes in interest rates. We may also enter into TBA contracts as a means of acquiring or disposing of agency RMBS and we may from time to time utilize TBA dollar roll transactions to finance agency RMBS purchases.

We account for all TBA contracts as derivatives since we cannot assert that it is probable at the inception and throughout the term of the contract that it will not settle net and will result in physical delivery of an agency security when it is issued. A TBA dollar roll transaction is a series of derivative transactions. The net settlement of a TBA contract is reported as realized gain on other derivatives and securities, net and changes in the fair value of our TBA contracts are reported as unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations.

We estimate the fair value of TBA securities based on similar methods used to value our agency RMBS.

Forward commitments to purchase or sell specified securities

We may enter into a forward commitment to purchase or sell specified securities as a means of acquiring assets or as a hedge against short-term changes in interest rates. Such forward commitments usually require physical settlement. Contracts for the purchase or sale of specified securities are accounted for as derivatives if the delivery of the specified agency RMBS and settlement extends beyond established market conventions. Realized gains and losses associated with forward commitments are recognized in realized gain on other derivatives and securities, net and unrealized gains and losses are recognized in unrealized gain (loss) on other derivatives and securities, net on our consolidated statements of operations.

We estimate the fair value of forward commitments to purchase or sell specified RMBS based on methods used to value our RMBS, as well as the remaining length of time of the forward commitment.

Organization [Abstract]

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

Organization

We were incorporated in Maryland on March 15, 2011 and commenced operations on August 9, 2011 following the completion of our initial public offering ("IPO"). We are externally managed by American Capital MTGE Management, LLC (our "Manager"), an affiliate of American Capital, Ltd. ("American Capital"). Our common stock is traded on the NASDAQ Global Select Market under the symbol "MTGE."

We invest in, finance and manage a leveraged portfolio of mortgage-related investments, which we define to include agency residential mortgage-backed securities ("RMBS"), non-agency mortgage investments and other mortgage-related investments. Agency RMBS include residential mortgage pass-through certificates and collateralized mortgage obligations ("CMOs") structured from residential mortgage pass-through certificates for which the principal and interest payments are guaranteed by a government-sponsored enterprise ("GSE"), such as Federal National Mortgage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation ("Freddie Mac"), or by a U.S. Government agency, such as Government National Mortgage Association ("Ginnie Mae"). Non-agency mortgage investments include RMBS backed by residential mortgages that are not guaranteed by a GSE or U.S. Government agency. Non-agency mortgage investments may also include prime and non-prime residential mortgage loans. Other mortgage-related investments may include mortgage servicing rights ("MSR"), GSE credit risk transfer securities, commercial mortgage-backed securities ("CMBS"), commercial mortgage loans and mortgage-related derivatives.

Our objective is to provide attractive risk-adjusted returns to our stockholders over the long-term through a combination of dividends and net book value appreciation. In pursuing this objective, we rely on our Manager’s expertise to construct and manage a diversified mortgage investment portfolio by identifying asset classes that, when properly financed and hedged, are designed to produce attractive returns across a variety of market conditions and economic cycles, considering the risks associated with owning such investments.

We have elected 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 at least 90% of our taxable net 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 net income to the extent that we distribute all of our annual taxable net income to our stockholders. It is our intention to distribute 100% of our taxable net income, after application of available tax attributes, within the time limits prescribed by the Internal Revenue Code, which may extend into the subsequent taxable year.

On November 27, 2013, our wholly-owned subsidiary, American Capital Mortgage 2013, LLC acquired RCS, a fully-licensed mortgage servicer based in Fort Worth, Texas that has approvals from Fannie Mae, Freddie Mac, and Ginnie Mae to hold and manage MSR and residential mortgage loans. See Note 11 - Other Assets for additional information.

Unaudited Interim Consolidated Financial Statements [Text Block]

Unaudited Interim Consolidated Financial Statements

The unaudited interim consolidated financial statements of American Capital Mortgage Investment Corp. (referred to 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 our wholly-owned subsidiaries, American Capital Mortgage Investment TRS, LLC and American Capital Mortgage 2013, LLC and, in turn, its wholly-owned subsidiary Residential Credit Solutions, Inc. ("RCS"). 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.

Disclosure of Repurchase Agreements [Abstract]

Repurchase Agreements

Repurchase Agreements

We pledge certain of our securities as collateral under repurchase arrangements with financial institutions, the terms and conditions of which are negotiated on a transaction-by-transaction basis. Interest rates on these borrowings are generally based on LIBOR plus or minus a margin and amounts 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. In response to declines in fair value of pledged securities, lenders may require us to post additional collateral or pay down borrowings to re-establish agreed upon collateral requirements, referred to as margin calls. As of September 30, 2014 and December 31, 2013, we have met all margin call requirements and had no agency or non-agency repurchase agreements with original overnight maturities. Repurchase agreements are carried at cost, which approximates fair value due to their short-term nature.

At September 30, 2014 and December 31, 2013, our borrowings under repurchase agreements had the following collateral characteristics (dollars in thousands):

	September 30, 2014					December 31, 2013

We had repurchase agreements with 33 and 31 financial institutions as of September 30, 2014 and December 31, 2013, respectively. In addition, less than 5% of stockholders' equity was at risk due to collateral pledged in excess of borrowings under repurchase agreements with any one counterparty, with the top five counterparties representing less than 18% of our equity at risk as of September 30, 2014.

We had agency RMBS with fair values of $4.1 billion and $5.6 billion and non-agency RMBS with fair values of $0.8 billion and $0.9 billion pledged as collateral against repurchase agreements, as of September 30, 2014 and December 31, 2013, respectively.

Our Prime non-agency RMBS include investments in securitization trusts collateralized by prime mortgage loans, which are residential mortgage loans that are considered to have been originated with the most stringent underwriting standards at the time of origination. Our Prime securities with a combined fair value of $175.6 million as of September 30, 2014 are collateralized by loans that were originated between 2003 and 2006, a period of generally weaker underwriting standards and elevated housing prices. As a result, there is still material credit risk embedded in these vintages. As of September 30, 2014, Prime securities also include $81.5 million in fair value of securities with underlying mortgage loans that were originated with more stringent underwriting during 2012 and 2013. As of September 30, 2014, our Prime securities have both floating-rate and fixed-rate coupons ranging from 0.8% to 6.5%, with weighted average coupons of underlying collateral ranging from 2.4% to 5.8%.

Our Alt-A non-agency RMBS are collateralized by Alt-A mortgage loans that were originated from 2002 to 2007. Alt-A, or alternative A-paper, mortgage loans are considered to have more credit risk than prime mortgage loans and less credit risk than sub-prime mortgage loans. Alt-A loans are typically characterized by borrowers with less than full documentation, lower credit scores, higher loan-to-value ratios and a higher percentage of investment properties. As of September 30, 2014, our Alt-A securities have both fixed and floating rate coupons ranging from 0.2% to 6.5% with weighted average coupons of underlying collateral ranging from 2.7% to 6.9%.

Our Option-ARM non-agency RMBS include senior tranches in securitization trusts that are collateralized by residential mortgages that have origination and underwriting characteristics similar to Alt-A mortgage loans, with the added feature of providing underlying mortgage borrowers the option, within certain constraints, to make lower payments than otherwise required by the stated interest rate for a number of years, leading to negative amortization and increased loan balances. This additional feature can increase the credit risk of these securities. As of September 30, 2014, our Option-ARM securities have coupons ranging from 0.3% to 1.1% and have underlying collateral with weighted average coupons between 2.7% and 3.5%. The loans underlying our Option-ARM securities were originated between 2004 and 2007.

Our Subprime non-agency RMBS issued prior to 2013 include fixed and floating rate, senior tranches in securitization trusts collateralized by residential mortgages originated from 2003 to 2007 that were originally considered to be of lower credit quality. As of September 30, 2014, our Subprime securities issued prior to 2013 have a fair value of $139.6 million with fixed and floating rate coupons ranging from 0.2% to 5.4% and have underlying collateral with weighted-average coupons ranging from 4.5% to 7.8%. Additionally, we have classified certain non-performing loans that were securitized in 2013 and 2014 as Subprime securities. These 2013 and 2014 securitizations are backed by loans originated during or before 2010 and, as of September 30, 2014, have a fair value of $15.6 million. As of September 30, 2014, our Subprime securities issued in 2013 and 2014 have fixed rate coupons ranging from 3.3% to 4.3% and have underlying collateral with weighted-average coupons ranging from 5.7% to 8.4%.

More than 98% of our non-agency RMBS are rated below investment grade or have not been rated by credit agencies as of September 30, 2014.

Stockholders' Equity Note Disclosure [Text Block]

Stockholders’ Equity

Preferred Stock Offering

Pursuant to our charter, we are authorized to designate and issue up to 50.0 million shares of preferred stock in one or more classes or series. Our Board of Directors has designated 2.3 million shares as 8.125% Series A Cumulative Redeemable Preferred Stock ("Series A Preferred Stock"). As of September 30, 2014, we have 47.8 million of authorized but unissued shares of preferred stock. Our Board of Directors may designate additional series of authorized preferred stock ranking junior to or in parity with the Series A Preferred Stock or designate additional shares of the Series A Preferred Stock and authorize the issuance of such shares.

In May 2014, we completed a public offering in which 2.2 million shares of our Series A Preferred Stock were sold to the underwriters at a price of $24.2125 per share. Upon completion of the offering we received proceeds, net of offering expenses, of approximately $53.0 million. Our Series A Preferred Stock has no stated maturity and is not subject to any sinking fund or mandatory redemption. Under certain circumstances upon a change of control, the Series A Preferred Stock is convertible to shares of our common stock. Holders of Series A Preferred Stock have no voting rights, except under limited conditions, and holders are entitled to receive cumulative cash dividends at a rate of 8.125% per annum of the $25.00 per share liquidation preference before holders of our common stock are entitled to receive any dividends. Shares of our Series A Preferred Stock are redeemable at $25.00 per share plus accumulated and unpaid dividends (whether or not declared) exclusively at our option commencing on May 22, 2019, or earlier under certain circumstances intended to preserve our qualification as a REIT for Federal income tax purposes. Dividends are payable quarterly in arrears on the 15th day of each January, April, July and October. As of September 30, 2014, we had declared all required quarterly dividends on the Series A Preferred Stock.

Stock Repurchase Program

In October 2012, our Board of Directors adopted a program that provided for stock repurchases of up to $50 million of our outstanding shares of common stock through December 31, 2013. In June 2013, our Board of Directors authorized the repurchase of up to an additional $100 million of our outstanding shares of common stock through December 31, 2013. In September 2013, our Board of Directors authorized the repurchase of up to an additional $150 million of our outstanding shares of common stock and extended its authorization through December 31, 2014. In October 2014, our Board of Directors extended the Company's existing stock repurchase program through December 31, 2015.

We did not repurchase any shares of our common stock during the three months ended September 30, 2014. During the nine months ended September 30, 2014, we repurchased approximately 0.2 million shares of our common stock at an average repurchase price of $19.67 per share, including expenses, totaling $4.2 million. As of September 30, 2014, we had an additional $134.9 million available for repurchases of our common stock through December 31, 2015, as authorized by the Board of Directors.

Dividend Reinvestment and Direct Stock Purchase Plan

We sponsor a dividend reinvestment and direct stock purchase plan through which stockholders may purchase additional shares of our common stock by reinvesting some or all of the cash dividends received on shares of our common stock. Stockholders may also make optional cash purchases of shares of our common stock subject to certain limitations detailed in the plan prospectus. We did not issue any shares under the plan during the three and nine months ended September 30, 2014.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Fair Value Measurements

We have elected the option to account for all of our financial assets, including RMBS, at fair value, with changes in fair value reflected in income during the period in which they occur. We have determined that this presentation most appropriately represents our financial results and position. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, based on the assumptions market participants would use when pricing an asset or liability.

We determine the fair value of our agency and non-agency RMBS, including securities held as collateral, 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 recent trading activity, 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, default and loss severity, especially when estimating fair values for securities with lower levels of recent trading activity. When possible, we make inquiries of third-party pricing sources to understand their use of significant inputs and assumptions.

We review the various third-party fair value estimates and perform procedures to validate their reasonableness, including an analysis of the range of third-party estimates for each position, comparison to recent trade activity for similar securities, and our Manager's review 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 determination of fair value if we determine (based on our validation procedures and our Manager's market knowledge and expertise) that the price is significantly different than observable market data would indicate and we cannot obtain a satisfactory understanding from the third party source as to the significant inputs used to determine the price.

We determine the fair value of our MSR based upon discounted cash flow models that are primarily based on observable market-based inputs but also include substantial unobservable market data inputs (including prepayment speeds, delinquency levels and discount rates).

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. We use the results of the validation procedures described above as part of our determination of the appropriate fair value measurement hierarchy classification. The three levels of 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 - Significant unobservable market inputs that are supported by little or no market activity. The unobservable inputs represent the assumptions that market participants would use to price the assets and liabilities.

The following tables present our financial instruments carried at fair value as of September 30, 2014 and December 31, 2013, on the consolidated balance sheets by the valuation hierarchy, as described above (in thousands):

Our agency and non-agency RMBS are valued using the various market data described above, which include inputs determined to be observable or whose significant value drivers are observable. Accordingly, our agency and non-agency RMBS are classified as Level 2 in the fair value hierarchy as of September 30, 2014. We estimate the fair value of our REIT equity securities on a market approach using Level 1 inputs, based on quoted market prices.

For information regarding valuation of our derivative instruments, please refer to the discussion of derivative and other hedging instruments in Note 3. Our interest rate swaps and other derivatives are classified as Level 2 in the fair value hierarchy.

The fair value of our obligation to return securities borrowed under reverse repurchase agreements is based upon the value of the underlying borrowed U.S. Treasury securities as of the reporting date. Both U.S. Treasury securities and our obligation to return borrowed U.S. Treasury securities are classified as Level 1 in the fair value hierarchy.

The following table presents a summary of the changes in fair value for Level 3 assets carried at fair value as of September 30, 2014 (in thousands):

⁽¹⁾ Gains (losses) included in net income related to MSR under secured financing are offset in their entirety by (losses) gains associated with related MSR financing liabilities.

We use third-party pricing providers in the fair value measurement of our Level 3 MSR. The significant unobservable inputs used in estimating the fair value measurement of our Level 3 MSR assets and financing liabilities include assumptions for underlying loan constant prepayment rates and delinquency rates, as well as discount rates. We review the various third-party fair value estimates used to determine the fair value of our MSR and perform procedures to validate their reasonableness. In reviewing the estimated fair values of our Level 3 MSR, we use internal models and our own estimates of prepayment and

delinquency rates on the loans underlying our MSR.

The following table presents the range of our estimates of loan constant voluntary prepayment rates and constant default rates, together with the discount rates used by third-party pricing providers in estimating the fair value of our Level 3 MSR as of September 30, 2014 (dollars in thousands):

	September 30, 2014
Unobservable Level 3 Input	Fair Value		Minimum	Weighted Average	Maximum
MSR treated as financing arrangements:	$	14,470
Constant prepayment rate			9.7%	14.7%	34.5%
Constant default rate			—%	7.4%	28.2%
Discount rate			16.0%	16.0%	16.0%
Purchased MSR:	85,844
Constant prepayment rate			7.3%	7.7%	8.1%
Constant default rate			0.2%	0.3%	0.4%
Discount rate			8.3%	8.7%	9.3%
Total	$	100,314

Our MSR treated as financing arrangements relate to private label mortgages with an average origination year of 2005, whereas our purchased MSR relate to more recently originated mortgages that conform to GSE underwriting standards. Private label originations from the pre-2009 era have experienced heightened default rates relative to recently originated conforming mortgages. As such, we anticipate that the default rate and discount rate for our MSR treated as financing arrangements will exceed the default rate and discount rate for our purchased MSR.

A significant increase in any one of these individual inputs in isolation would likely result in a decrease in fair value measurement. Additionally, a change in the assumption used for discount rates may be accompanied by a directionally similar change in the assumption used for the probability of delinquency and a directionally opposite change in the assumption used for prepayment rates. Overall MSR market conditions could have a more significant impact on our Level 3 fair values than changes in any one unobservable input.

Derivative Instruments [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Derivatives and Other Securities

In connection with our risk management strategy, we hedge a portion of our exposure to market risks, including interest rate risk and prepayment risk, by entering into derivative and other hedging instrument contracts. We may enter into agreements for interest rate swaps, interest rate swaptions, interest rate cap or floor contracts and futures or forward contracts. We may also purchase or short TBA and U.S. Treasury securities, purchase or write put or call options on TBA securities or we may invest in other types of derivative securities, including synthetic total return swaps and credit default swaps. Our risk management strategy attempts to manage the overall risk of the portfolio and reduce fluctuations in book value. We do not use derivative or other hedging instruments for speculative purposes. Derivatives have not been designated as hedging instruments. We do not offset our derivatives and related cash collateral with the same counterparties under any master netting arrangements. For additional information regarding our derivative instruments and our overall risk management strategy, please refer to the discussion of derivatives in Note 3 - Summary of Significant Accounting Policies.

Interest Rate Swap Agreements

As of September 30, 2014 and December 31, 2013, our derivative portfolio included interest rate swaps, which have the effect of modifying the repricing characteristics of our repurchase agreements and cash flows on such liabilities. Our interest rate swaps are used to manage the interest rate risk created by our use of short-term repurchase agreements. Under our interest rate swaps, we typically pay a fixed rate and receive a floating rate based on LIBOR with terms usually ranging up to 15 years. As of September 30, 2014 and December 31, 2013, we had interest rate swap agreements summarized in the tables below (dollars in thousands).

⁽¹⁾  Notional amount represents the par value or principal balance of the underlying agency security.

⁽²⁾  Fair value represents the current market value of the agency RMBS underlying the TBA contract as of period end, less the forward price to be paid for the underlying agency RMBS.

U.S. Treasury Securities and Futures

We purchase or sell short 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 had U.S. Treasury securities with a fair value of $467.2 million and $637.3 million and a face amount of $472.0 million and $656.0 million as of September 30, 2014 and December 31, 2013, respectively, which is presented as Treasury securities, at fair value on the consolidated balance sheets. In addition, we had a short position in U.S. Treasury futures with a fair value of $1.2 million and $3.4 million, respectively, and a notional amount of $(150.0) million as of both September 30, 2014 and December 31, 2013, which is presented in derivative assets, at fair value on the consolidated balance sheets.

We had obligations to return U.S. Treasury securities borrowed under reverse repurchase agreements accounted for as securities borrowing transactions with a fair value of $742.6 million and $22.5 million as of September 30, 2014 and December 31, 2013, respectively. The borrowed securities were collateralized by cash payments of $745.4 million and $22.7 million as of September 30, 2014 and December 31, 2013, respectively, which are presented as receivables under reverse repurchase agreements on the consolidated balance sheets. All changes in fair value of long and short U.S. Treasury securities and futures are recorded in unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations.

REIT Equity Securities, at Fair Value

As of December 31, 2013, we held shares of common stock of several publicly-traded mortgage REITs with a cost basis of $39.3 million and a total fair value of $38.8 million. As of September 30, 2014, we no longer held any positions in these securities and for the nine months ended September 30, 2014, we recognized $6.8 million of net realized gains on disposal and $1.8 million in dividend income which are both included in realized gain on other derivatives and securities, net in our consolidated statements of operations.

Credit Risk-Related Contingent Features

The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. We minimize this risk by limiting our counterparties for instruments which are not centrally cleared on a registered exchange to major financial institutions with acceptable credit ratings and monitoring positions with individual counterparties. In addition, both we and our counterparties may be required to pledge assets as collateral for our derivatives, whose amounts vary over time based on the market value, notional amount and remaining term of the derivative contract. In the event of a default by a counterparty, we may not receive payments provided for under the terms of our derivative agreements, and may have difficulty obtaining our assets pledged as collateral for our derivatives. The cash and cash equivalents pledged as collateral for our derivative instruments is included in restricted cash and cash equivalents on our consolidated balance sheets.

Each of our ISDA Master Agreements contains provisions pursuant to which we are required to fully collateralize our obligations under our interest rate swap agreements if at any point the fair value of the swap represents a liability greater than the minimum transfer amount contained within our ISDA Master Agreements. We are also required to post initial collateral upon execution of certain of our swap transactions. If we breach any of these provisions, we will be required to settle our obligations under the agreements at their termination values, which approximates fair value.

Further, each of our ISDA Master Agreements also contains a cross default provision under which a default under certain of our other indebtedness in excess of a certain threshold causes an event of default under the agreement. Threshold amounts vary by lender. Following an event of default, we could be required to settle our obligations under the agreements at their termination values. Additionally, under certain of our ISDA Master Agreements, we could be required to settle our obligations under the agreements at their termination values if we fail to maintain either our REIT status or certain minimum stockholders’ equity thresholds, or comply with limits on our leverage above certain specified levels. As of September 30, 2014, the fair value of the 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 consolidated financial statements.

Concerning our non-centrally cleared interest rate swap and swaption agreements, we did not have counterparty credit risk with any single counterparty in excess of 1% of our stockholders’ equity, as of September 30, 2014.

In the case of centrally cleared interest rate swap contracts, 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, the risk is considered minimal due to initial and daily exchange of mark to market margin requirements and the clearinghouse guarantee fund and other resources that are available in the event of a clearing member default.

Offsetting Assets and Liabilities

Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of offset 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 such agreements and can potentially be offset on our consolidated balance sheets as of September 30, 2014 and December 31, 2013 (in thousands):

Mortgage Servicing Rights (Notes)

Servicing Assets at Fair Value [Line Items]

Transfers and Servicing of Financial Assets [Text Block]

Mortgage Servicing Rights

Our $100.3 million balance of MSR as of September 30, 2014 includes $14.5 million related to RCS' acquisition of certain MSR covering private label residential mortgage pools, for which RCS entered into sale and assignment agreements with a third party to transfer its interest in the excess MSR while retaining the actual servicing function. These transfers do not qualify for sale accounting and are treated as financing arrangements, under which we recognize both MSR assets and MSR corresponding MSR financing liabilities. Changes in the fair value of assets and liabilities resulting from MSR financing transactions have no net impact on the consolidated statements of operations.

The remaining $85.8 million of MSR were purchased by RCS during the nine months ended September 30, 2014 under transactions qualifying for sale accounting, representing approximately 34,608 underlying loans, with a combined unpaid principal balance of approximately $7.3 billion as of September 30, 2014. We have elected to account for all MSR assets and MSR financing liabilities at estimated fair value with changes in fair value reported in net income. The following table summarizes activity related to MSR accounted for as purchases during the nine months ended September 30, 2014 (dollars in thousands):

	For the Nine Months Ended September 30, 2014
Balance as of December 31, 2013	$	—
Additions from purchases of MSR	93,414
Changes in fair value due to:
Changes in valuation inputs or assumptions used in valuation model	(3,705		)
Other changes in fair value (1)	(2,830		)
Other changes (2)	(1,035		)
Balance as of September 30, 2014	$	85,844

————————

1. Other changes in fair value primarily represents changes due to the realization of cash flows.

2. Other changes includes purchase price adjustments, principally contractual prepayment protection.

The following table presents the components of net servicing loss for the three and nine months ended September 30, 2014 (dollars in thousands):

Risk Mitigation Activities

The Company’s acquisitions of MSR expose us to certain risks, including interest rate risk and representation and warranty risk. A significant decline in interest rates could lead to higher-than-expected prepayments that could reduce the value of the MSR. Our primary method of managing the prepayment risk associated with our MSR portfolio is asset selection, both in respect of products and the originators of the underlying loans. Representation and warranty risk refers to the representations and warranties we make (or are deemed to have made) to the applicable investor (including, without limitation, the GSEs) regarding, among other things, the origination and servicing of mortgage loans with respect to which we have acquired MSR. We mitigate representation and warranty risk through our due diligence in connection with MSR acquisitions, including counterparty reviews and loan file reviews, as well as negotiated contractual protections from our MSR transaction counterparties with respect to origination and prior servicing.

⁽¹⁾ Gains (losses) included in net income related to MSR under secured financing are offset in their entirety by (losses) gains associated with related MSR financing liabilities.

We use third-party pricing providers in the fair value measurement of our Level 3 MSR. The significant unobservable inputs used in estimating the fair value measurement of our Level 3 MSR assets and financing liabilities include assumptions for underlying loan constant prepayment rates and delinquency rates, as well as discount rates. We review the various third-party fair value estimates used to determine the fair value of our MSR and perform procedures to validate their reasonableness. In reviewing the estimated fair values of our Level 3 MSR, we use internal models and our own estimates of prepayment and

delinquency rates on the loans underlying our MSR.

Actual maturities of agency RMBS are generally shorter than the stated contractual maturities. Actual maturities are affected by the contractual lives of the underlying mortgages, periodic principal payments and principal prepayments.

The following table summarizes our agency RMBS as of September 30, 2014 and December 31, 2013 according to their estimated weighted average life classification (dollars in thousands):

As of September 30, 2014 and December 31, 2013, none of our agency RMBS had an estimated weighted average life of less than 3.4 years and 2.1 years, respectively. As of September 30, 2014 and December 31, 2013, the estimated weighted average life of our agency security portfolio was 7.1 years and 6.1 years, respectively, which incorporates anticipated future prepayment assumptions. As of September 30, 2014 and December 31, 2013, our weighted average expected constant prepayment rate ("CPR") over the remaining life of our aggregate agency investment portfolio was 8% and 7%, respectively. Our estimates differ materially for different types of securities and thus individual holdings have a wide range of projected CPRs. We estimate long-term prepayment rates using a third-party service and market data. We review the prepayment speeds estimated by the third-party service and compare the results to market consensus prepayment speeds, if available. We also consider historical prepayment speeds and current market conditions to validate reasonableness. As market conditions may change rapidly, we use our judgment in developing our estimates for different securities. Prepayments are dependent on many factors and actual prepayments could differ materially from our estimates. Various market participants could use materially different assumptions. Furthermore, changes in market conditions such as interest rates, housing prices, and broad economic factors such as employment can materially impact prepayments. Additionally, modifications to GSE underwriting criteria or programs, GSE policies surrounding the buyouts or modifications of delinquent loans or other factors could significantly change the prepayment landscape.

Fair Value of Financial Assets [Abstract]

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Assets

We have elected the option to account for all of our financial assets, including all mortgage-related investments, at estimated fair value, with changes in fair value reflected in income during the period in which they occur. In management's view, this election more appropriately reflects the results of our operations for a particular reporting period, as financial asset fair value changes are presented in a manner consistent with the presentation and timing of the fair value changes of hedging instruments. See Note 9 - Fair Value Measurements.

Revenue Recognition, Policy [Policy Text Block]

Interest Income

Interest income is accrued based on the outstanding principal amount of the securities and their contractual terms. Premiums or discounts associated with the purchase of agency RMBS and non-agency RMBS 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.

We estimate long-term prepayment speeds using a third-party service and market data. The third-party service estimates prepayment speeds for our securities using models that incorporate the mortgage rates, age, size and loan-to-value ratios of the outstanding underlying loans, as well as current mortgage rates, forward yield curves, volatility and other factors. We review the prepayment speeds estimated by the third-party service and compare the results to market consensus prepayment speeds, if available. We also consider historical prepayment speeds and current market conditions to validate the reasonableness of the prepayment speeds estimated by the third-party service, and based on our Manager’s judgment, we may make adjustments to its estimates. Actual and anticipated prepayment experience is reviewed at least quarterly and effective yields are recalculated when differences arise between the previously estimated future prepayments and the amounts actually received plus currently anticipated future prepayments. If the actual and anticipated future prepayment experience differs from our prior estimate of prepayments, we are required to record an adjustment in the current period to the amortization or accretion of premiums and discounts for the cumulative difference in the effective yield through the reporting date.

At the time we purchase non-agency RMBS and loans 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 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 input and analysis received from external sources, internal models, and our judgment about interest rates, prepayment rates, the timing and amount of credit losses, 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, if any.

Transfers and Servicing of Financial Assets, Servicing of Financial Assets, Policy [Policy Text Block]

Mortgage Servicing Rights, at Fair Value

Our MSR represent the right to service mortgage loans for a servicing fee. MSR are reported at fair value on our consolidated balance sheets, with changes in fair value related to changes in valuation inputs and assumptions reported as unrealized loss on MSR on the consolidated statements of operations. Servicing fees, incentive fees and ancillary income are reported within servicing income on the consolidated statements of operations. The related servicing expenses and realization of cash flows related to underlying loan repayments, net of recoveries of contractual prepayment protection, are recorded in servicing expenses on the consolidated statements of operations. See Note 10 - Mortgage Servicing Rights for further discussion on MSR.

The accounting model used to evaluate whether a transfer of MSR qualifies as a sale is based on a risks and rewards approach, as MSR are not financial assets. In certain cases where we transfer the economics of MSR while retaining the actual servicing function, we retain the risk associated with servicing and, as a result, the transfer does not qualify for sale accounting. As such, we retain the MSR, together with an offsetting financing liability on our consolidated balance sheets. We have elected the option to account for MSR financing liabilities at estimated fair value, with changes in fair value reflected in income during the period in which they occur. See Note 12 - Accounts Payable and Other Accrued Liabilities for the presentations of our mortgage servicing liability.

We may be obligated to fund advances of principal and interest payments due to third party owners of the loans but not yet received from the individual borrowers. We may also be obligated to fund advances of real estate taxes and insurance, protective advances to preserve the value of the underlying property, and expenses associated with remedial action in respect of defaulted loans. These servicing advances are reported within other assets on the consolidated balance sheets.

Marketable Securities, Policy [Policy Text Block]

REIT Equity Securities, at Fair Value

REIT equity securities represent investments in the common stock of other publicly traded mortgage REITs that invest predominately in agency RMBS. We designate our investments in REIT equity securities as trading securities and report them at fair value on the accompanying consolidated balance sheets with changes in fair value recorded in unrealized gain (loss) on other derivatives and securities, net on the accompanying consolidated statements of operations. Dividend income from REIT equity securities is recorded in realized gain on other derivatives and securities, net.

Repurchase Agreements, Valuation, Policy [Policy Text Block]

Repurchase Agreements

We finance the acquisition of agency RMBS and certain non-agency RMBS for our investment portfolio through repurchase transactions under master repurchase agreements. We account for repurchase transactions as collateralized financing transactions which are carried at their contractual amounts, including accrued interest, as specified in the respective transaction agreements. The contractual amounts approximate fair value due to their short-term nature.

Repurchase and Resale Agreements Policy [Policy Text Block]

Reverse Repurchase Agreements and Obligation to Return Securities Borrowed under Reverse Repurchase Agreements

From time to time we borrow securities to cover short sales of U.S. Treasury securities through reverse repurchase transactions under our master repurchase agreements (see Derivatives below). We account for these as securities borrowing transactions and recognize an obligation to return the borrowed securities at fair value on the consolidated balance sheets based on the value of the underlying borrowed securities as of the reporting date. Our reverse repurchase agreements generally mature daily. The fair value of our reverse repurchase agreements is assumed to equal cost as the interest rates are reset daily.

Derivatives, Policy [Policy Text Block]

Derivatives

We utilize a risk management strategy, under which we may use a variety of derivative instruments to hedge some of our exposure to market risks, including interest rate risk, prepayment risk, extension risk and credit risk. The objective of our risk management strategy is to reduce fluctuations in net book value over a range of market conditions. The principal instruments that we currently use are interest rate swaps and options to enter into interest rate swaps ("interest rate swaptions"). We also utilize forward contracts for the purchase or sale of agency RMBS, or to-be-announced forward ("TBA") contracts, and short sales of U.S. Treasury securities and U.S. Treasury futures contracts. We may also purchase or write put or call options on TBA securities and we may invest in other types of mortgage derivatives, such as synthetic total return swaps.

We also enter into TBA contracts as a means of investing in and financing agency RMBS (thereby increasing our "at

risk" leverage) or as a means of disposing of or reducing our exposure to agency RMBS (thereby reducing our "at risk" leverage). Pursuant to TBA contracts, we agree to purchase or sell, for future delivery, agency RMBS with certain principal and interest terms and certain types of collateral, but the particular agency RMBS to be delivered are not identified until shortly before the TBA settlement date. We may also choose, prior to settlement, to move the settlement of these securities out to a later date by entering into an offsetting short or long position (referred to as a "pair off"), net settling the paired off positions for cash, and simultaneously purchasing or selling a similar TBA contract for a later settlement date. This transaction is commonly referred to as a "dollar roll." The agency RMBS purchased or sold for a forward settlement date are typically priced at a discount to agency RMBS for settlement in the current month. This difference (or discount) is referred to as the "price drop." The price drop is the economic equivalent of net interest carry income on the underlying agency RMBS over the roll period (interest income less implied financing cost) and is commonly referred to as "dollar roll income (loss)." Consequently, forward purchases of agency RMBS and dollar roll transactions represent a form of off-balance sheet financing.

We recognize all derivative instruments as either assets or liabilities on the balance sheets, measured at fair value. As we have not designated any derivatives as hedging instruments, all changes in fair value are reported in earnings in our consolidated statements of operations in unrealized gain (loss) on other derivatives and securities, net during the period in which they occur. Derivatives in a gain position are reported as derivative assets at fair value and derivatives in a loss position are reported as derivative liabilities at fair value in our consolidated balance sheets. Cash receipts and payments related to 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.

Our derivative agreements generally contain provisions that allow for netting or setting off derivative assets and liabilities with each counterparty; however, we report related assets and liabilities on a gross basis in our consolidated balance sheets.

The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. We attempt to minimize this risk by limiting our counterparties to major financial institutions with acceptable credit ratings, monitoring positions with individual counterparties and adjusting posted collateral as required.

Interest rate swap agreements

We use interest rate swaps to hedge the variable cash flows associated with short-term borrowings made under our repurchase agreement facilities. 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") with terms up to 15 years. The floating rate we receive under our swap agreements has the effect of offsetting the repricing characteristics of our repurchase agreements and cash flows on such liabilities. Our swap agreements are privately negotiated in the over-the-counter ("OTC") market and may be centrally cleared through a registered commodities exchange ("centrally cleared swaps").

We estimate the fair value of our centrally cleared interest rate swaps using the daily settlement price determined by the respective exchange. Centrally cleared swaps are valued by the exchange using a pricing model that references the underlying rates, including the overnight index swap rate and LIBOR forward rate, to produce the daily settlement price. We estimate the fair value of our "non-centrally cleared" swaps using a combination of inputs from counterparty and third-party pricing models to estimate the net present value of the future cash flows using a forward yield curve in effect as of the end of the measurement period. We also incorporate any of our own and our counterparties’ unmitigated nonperformance risk in estimating the fair value of our interest rate swaps. In considering the effect of nonperformance risk, we consider the impact of netting and credit enhancements, such as collateral postings and guarantees, and have concluded that our own and our counterparty credit risk is not significant to the overall valuation of these agreements.

The payment of periodic settlements of net interest on interest rate swaps is reported in realized loss on periodic settlements of interest rate swaps, net in our consolidated statements of operations. Cash payments received or paid for the early termination of an interest rate swap agreement are recorded as realized gain on other derivatives and securities, net in our consolidated statements of operations. Changes in fair value of our interest rate swap agreements are reported in unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations.

Interest rate swaptions

We purchase interest rate swaptions to help mitigate the potential impact of larger increases or decreases in interest rates

on the performance of our investment portfolio. The interest rate swaptions provide us the option to enter into an interest rate swap agreement for a predetermined notional amount, stated term and pay or receive interest rates in the future. The premium paid for interest rate swaptions is reported as a derivative asset in our consolidated balance sheets. We estimate the fair value of interest rate swaptions 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. The difference between the premium and the fair value of the swaption is reported in unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations. If a swaption expires unexercised, the realized loss on the swaption would be equal to the premium paid and reported in realized gain on other derivatives and securities, net in our consolidated statements of operations. If we exercise a swaption, the realized gain or loss on the swaption would be equal to the difference between the fair value of the underlying interest rate swap and the premium paid and reported in realized gain on other derivatives and securities, net in our consolidated statements of operations.

Interest rate swaption agreements are privately negotiated in the OTC market and are not subject to central clearing. 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.

TBA securities

A TBA security is a forward contract for the purchase ("long position") or sale ("short position") of agency RMBS at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific agency RMBS delivered into the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association, are not known at the time of the transaction. We may enter into TBA contracts as a means of hedging against short-term changes in interest rates. We may also enter into TBA contracts as a means of acquiring or disposing of agency RMBS and we may from time to time utilize TBA dollar roll transactions to finance agency RMBS purchases.

We account for all TBA contracts as derivatives since we cannot assert that it is probable at the inception and throughout the term of the contract that it will not settle net and will result in physical delivery of an agency security when it is issued. A TBA dollar roll transaction is a series of derivative transactions. The net settlement of a TBA contract is reported as realized gain on other derivatives and securities, net and changes in the fair value of our TBA contracts are reported as unrealized gain (loss) on other derivatives and securities, net in our consolidated statements of operations.

We estimate the fair value of TBA securities based on similar methods used to value our agency RMBS.

Forward commitments to purchase or sell specified securities

We may enter into a forward commitment to purchase or sell specified securities as a means of acquiring assets or as a hedge against short-term changes in interest rates. Such forward commitments usually require physical settlement. Contracts for the purchase or sale of specified securities are accounted for as derivatives if the delivery of the specified agency RMBS and settlement extends beyond established market conventions. Realized gains and losses associated with forward commitments are recognized in realized gain on other derivatives and securities, net and unrealized gains and losses are recognized in unrealized gain (loss) on other derivatives and securities, net on our consolidated statements of operations.

We estimate the fair value of forward commitments to purchase or sell specified RMBS based on methods used to value our RMBS, as well as the remaining length of time of the forward commitment.

U.S. Treasury securities

We purchase or sell short 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. Realized gains and losses associated with purchases and short sales of U.S. Treasury securities and U.S. Treasury futures contracts are recognized in realized gain on other derivatives and securities, net, and unrealized gains and losses are recognized in unrealized gain (loss) on other derivatives and securities, net on our consolidated statements of operations.
