NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

DYNEX CAPITAL, INC.

(amounts in thousands except share and per share data)

NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

Dynex Capital, Inc., ("Company”) was incorporated in the Commonwealth of Virginia on December 18, 1987 and commenced operations in February 1988. The Company primarily earns income from investing on a leveraged basis in mortgage-backed securities ("MBS") that are issued or guaranteed by the U.S. Government or U.S. Government sponsored agencies ("Agency MBS") and MBS issued by others ("non-Agency MBS").

Basis of Presentation

The accompanying unaudited consolidated financial statements of Dynex Capital, Inc. and its subsidiaries (together, “Dynex” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10, Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all significant adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the consolidated financial statements have been included. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any other interim periods or for the entire year ending December 31, 2015. The unaudited consolidated financial statements included herein should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC.

Consolidation

The consolidated financial statements include the accounts of the Company and the accounts of its majority owned subsidiaries and variable interest entities ("VIE") for which it is the primary beneficiary. As a primary beneficiary, the Company has both the power to direct the activities that most significantly impact the economic performance of the VIE and a right to receive benefits or absorb losses of the entity that could be potentially significant to the VIE. The Company is required to reconsider its evaluation of whether to consolidate a VIE each reporting period, based upon changes in the facts and circumstances pertaining to the VIE. All intercompany accounts and transactions have been eliminated in consolidation.

The Company consolidates certain trusts through which it has securitized mortgage loans as a result of not meeting the sale criteria under GAAP at the time the financial assets were transferred to the trust. Additional information regarding the accounting policy for the Company's securitized mortgage loans is provided below under "Mortgage Loans Held for Investment, Net ".

Use of Estimates

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 the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenue and expenses during the reported period. Actual results could differ from those estimates. The most significant estimates used by management include, but are not limited to, fair value measurements of its investments, other-than-temporary impairments, contingencies, and amortization of premiums and discounts. These items are discussed further below within this note to the consolidated financial statements.

Income Taxes

The Company has elected to be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986 and the corresponding provisions of state law. To qualify as a REIT, the Company must meet certain tests including investing in primarily real estate-related assets and the required distribution of at least 90% of its annual REIT taxable income to stockholders after consideration of its net operating loss carryforward ("NOL") and not including taxable income retained in its taxable subsidiaries. As a REIT, the Company generally will not be subject to federal income tax on the amount of its income or gain that is distributed as dividends to shareholders.

5

NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

DYNEX CAPITAL, INC.

(amounts in thousands except share and per share data)

The Company assesses its tax positions for all open tax years and determines whether the Company has any material unrecognized liabilities in accordance with Accounting Standards Codification "ASC" Topic 740. The Company records these liabilities, if any, to the extent they are deemed more likely than not to have been incurred.

Net Income (Loss) Per Common Share

The Company did not have any potentially dilutive securities outstanding during the three months ended March 31, 2015 or March 31, 2014.

Holders of unvested shares of the Company's issued and outstanding restricted common stock are eligible to receive non-forfeitable dividends. As such, these unvested shares are considered participating securities as per ASC Topic 260-10 and therefore are included in the computation of basic net income (loss) per share using the two-class method. Upon vesting, restrictions on transfer expire on each share of restricted stock, and each such share of restricted stock is converted to one equal share of common stock.

Because the Company's 8.50% Series A Cumulative Redeemable Preferred Stock (the “Series A Preferred Stock”) and 7.625% Series B Cumulative Redeemable Preferred Stock (the “Series B Preferred Stock”) are redeemable at the Company's option for cash only and may convert into shares of common stock only upon a change of control of the Company, the effect of those shares is excluded from the calculation of diluted net income (loss) per common share.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and highly liquid investments with original maturities of three months or less.

Restricted Cash

Restricted cash consists of cash the Company has pledged to cover initial and variation margin with its counterparties.

Mortgage-Backed Securities

In accordance with ASC Topic 320, the Company has designated its investments in MBS as available-for-sale ("AFS"). All of the Company’s MBS are recorded at fair value on the consolidated balance sheet. Changes in fair value for the Company's AFS securities are reported in other comprehensive income ("OCI") until each security is collected, disposed of, or determined to be other than temporarily impaired. Although the Company generally intends to hold its AFS securities until maturity, it may sell any of these securities as part of the overall management of its business. Upon the sale of an AFS security, any unrealized gain or loss is reclassified out of accumulated other comprehensive income ("AOCI") into net income as a realized "gain (loss) on sale of investments, net" using the specific identification method.

The Company’s MBS pledged as collateral against repurchase agreements and derivative instruments are included in MBS on the consolidated balance sheets with the fair value of the MBS pledged disclosed parenthetically.

Interest Income, Premium Amortization, and Discount Accretion.Interest income on MBS is accrued based on the outstanding principal balance (or notional balance in the case of interest-only, or "IO", securities) and their contractual terms.  Premiums and discounts on Agency MBS as well as any non-Agency MBS rated 'AA' and higher at the time of purchase are amortized into interest income over the expected life of such securities using the effective yield method and adjustments to premium amortization are made for actual cash payments as well as changes in projected future cash payments in accordance with ASC Topic 310-20. The Company's projections of future cash payments are based on input and analysis received from external sources and internal models, and includes assumptions about the amount and timing of credit losses, loan prepayment rates, fluctuations in interest rates, and other factors. On at least a quarterly basis, the Company reviews and makes any necessary adjustments to its cash flow projections and updates the yield recognized on these assets.

6

NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

DYNEX CAPITAL, INC.

(amounts in thousands except share and per share data)

The Company holds non-Agency MBS that were rated less than 'AA' at the time of purchase by at least one national rating agency. These non-Agency MBS were purchased at discounts to their par value, which management does not believe to be substantial. The Company accretes the discount into income over the security's expected life, which reflects management's estimate of the security's projected cash flows in accordance with ASC Topic 325-40. Future changes in the timing of projected cash flows or differences arising between projected cash flows and actual cash flows received may result in a prospective change in the effective yield on those securities.

Determination of MBS Fair Value.The Company estimates the fair value of the majority of its MBS based upon prices obtained from third-party pricing services and broker quotes. The remainder of the Company's MBS are valued by discounting the estimated future cash flows derived from cash flow models that utilize information such as the security's coupon rate, estimated prepayment speeds, expected weighted average life, collateral composition, estimated future interest rates, expected losses, and credit enhancements as well as certain other relevant information. Refer to Note 6 for further discussion of MBS fair value measurements.

Other-than-Temporary Impairment.MBS is considered impaired when its fair value is less than its amortized cost. The Company evaluates all of its impaired MBS for other-than-temporary impairments ("OTTI") on at least a quarterly basis. An impairment is considered other-than-temporary if: (1) the Company intends to sell the MBS; (2) it is more likely than not that the Company will be required to sell the MBS before its fair value recovers; or (3) the Company does not expect to recover the full amortized cost basis of the MBS. If either of the first two conditions is met, the entire amount of the impairment is recognized in earnings. If the impairment is solely due to the inability to fully recover the amortized cost basis, the security is further analyzed to quantify any credit loss, which is the difference between the present value of cash flows expected to be collected on the MBS and its amortized cost. The credit loss, if any, is then recognized in earnings, while the balance of impairment related to other factors is recognized in other comprehensive income.

Following the recognition of an OTTI through earnings, a new cost basis is established for the security. Any subsequent recoveries in fair value may be accreted back into the amortized cost basis of the MBS on a prospective basis through interest income. Please see Note 2 for additional information related to the Company's evaluation for OTTI.

Mortgage Loans Held for Investment, Net

The Company originated or purchased mortgage loans from 1992 through 1998, and these mortgage loans are reported at amortized cost in accordance with ASC Topic 310-10. A portion of these loans is pledged as collateral to support the repayment of one remaining class of a securitization financing bond issued by the Company in 2002. The associated securitization financing bond is treated as debt of the Company and is presented as "non-recourse collateralized financing" on the consolidated balance sheet. Securitized mortgage loans can only be sold subject to the lien of the respective securitization financing indenture. An allowance has been established for currently existing and probable losses on the Company's mortgage loans held for investment.

Investment in Limited Partnership

The Company is a limited partner with a less than 50% interest in a limited partnership for which it does not have substantive participating or kick-out rights that overcome the general partner's presumption of control. The Company accounts for its investment in this limited partnership using the equity method of accounting, which requires initially recording an investment in the equity of an investee at cost and subsequently adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses, capital contributions and distributions, and other changes in equity.

Repurchase Agreements

Repurchase agreements are accounted for as secured borrowings under which the Company pledges its securities as collateral to secure a loan, which is equal in value to a specified percentage of the estimated fair value of the pledged collateral. The Company retains beneficial ownership of the pledged collateral. At the maturity of a repurchase agreement, the Company is required to repay the loan and concurrently receives back its pledged collateral from the lender or, with the consent of the lender, the Company may renew the agreement at the then prevailing financing rate. A repurchase agreement lender may require the Company to pledge additional collateral in the event of a decline in the fair value of the collateral pledged. Repurchase agreement financing is recourse to the Company and the assets pledged. Most of the Company’s repurchase agreements are based on the

7

NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

DYNEX CAPITAL, INC.

(amounts in thousands except share and per share data)

September 1996 version of the Bond Market Association Master Repurchase Agreement, which generally provides that the lender, as buyer, is responsible for obtaining collateral valuations from a generally recognized source agreed to by both the Company and the lender, or, in an instance when such source is not available, the value determination is made by the lender.

Derivative Instruments

The Company's derivative instruments, which currently include interest rate swaps and Eurodollar futures, are accounted for in accordance with ASC Topic 815, which requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet and to measure those instruments at fair value. All periodic interest costs and other changes in fair value, including gains and losses recognized upon termination, associated with derivative instruments are recorded in "gain (loss) on derivative instruments, net" on the Company's consolidated statement of comprehensive income. Please refer to Note 4 for additional information regarding the Company's accounting for its derivative instruments.

Although MBS have characteristics that meet the definition of a derivative instrument, ASC Topic 815 specifically excludes these instruments from its scope because they are accounted for as debt securities under ASC Topic 320.

Share-Based Compensation

Pursuant to the Company’s 2009 Stock and Incentive Plan ("SIP"), the Company may grant share-based compensation to eligible employees, directors or consultants or advisers to the Company, including stock awards, stock options, stock appreciation rights, dividend equivalent rights, performance shares, and restricted stock units. The Company's restricted stock currently issued and outstanding under this plan may be settled only in shares of its common stock, and therefore are treated as equity awards with their fair value measured at the grant date and recognized as compensation cost over the requisite service period with a corresponding credit to shareholders' equity. The requisite service period is the period during which an employee is required to provide service in exchange for an award, which is equivalent to the vesting period specified in the terms of the share-based based award. None of the Company's restricted stock awards have performance based conditions. The Company does not currently have any share-based compensation issued or outstanding other than restricted stock.

Contingencies

In the normal course of business, there are various lawsuits, claims, and other contingencies pending against the Company. On a quarterly basis, the Company evaluates whether to establish provisions for estimated losses from those matters in accordance with ASC Topic 450, which states that a liability is recognized for a contingent loss when: (a) the underlying causal event has occurred prior to the balance sheet date; (b) it is probable that a loss has been incurred; and (c) there is a reasonable basis for estimating that loss. A liability is not recognized for a contingent loss when it is only possible or remotely possible that a loss has been incurred, however, possible contingent losses shall be disclosed. If the contingent loss (or an additional loss in excess of any accrual) is at least a reasonable possibility and material, then the Company discloses a reasonable estimate of the possible loss or range of loss, if such reasonable estimate can be made. If the Company cannot make a reasonable estimate of the possible material loss, or range of loss, then that fact is disclosed. As of March 31, 2015, the Company does not have any contingencies for which it believes a probable loss has been incurred.

Recent Accounting Pronouncements

The Company does not believe there are any recently issued accounting pronouncements which will have a material effect on the Company's financial condition or results of operations upon their effective date.

NOTE 2 – MORTGAGE-BACKED SECURITIES

The majority of the Company's MBS are pledged as collateral to cover initial and variation margins for the Company's repurchase agreements and derivative instruments. The following tables provide detail by type of investment for the Company’s MBS designated as AFS as of the dates indicated:

The Company received proceeds of $102,923 and $59,799 for the sale of MBS during the three months ended March 31, 2015 and March 31, 2014, respectively. The following table presents the gross realized gains (losses) of those sales included in "gain (loss) on sale of investments, net" on the Company's consolidated statements of comprehensive income for the periods indicated:

	Three Months Ended

	Fair Value		Gross Unrealized Losses			# of Securities	Fair Value		Gross Unrealized Losses			# of Securities
Continuous unrealized loss position for less than 12 months:

Non-Agency MBS	1,224		(61		)	4	18,037		(159		)	5

Because the principal related to Agency MBS is guaranteed by the government-sponsored entities Fannie Mae and Freddie Mac which have the implicit guarantee of the U.S. government, the Company does not consider any of the unrealized losses on its Agency MBS to be credit related. Although the unrealized losses are not credit related, the Company assesses its ability and intent to hold any Agency MBS with an unrealized loss until the recovery in its value. This assessment is based on the amount of the unrealized loss and significance of the related investment as well as the Company’s current leverage and anticipated liquidity. Based on this analysis, the Company has determined that the unrealized losses on its Agency MBS as of March 31, 2015 and December 31, 2014 were temporary.

The Company also reviews any non-Agency MBS in an unrealized loss position to evaluate whether any decline in fair value represents an OTTI. The evaluation includes a review of the credit ratings of these non-Agency MBS and the seasoning of the mortgage loans collateralizing these securities as well as the estimated future cash flows which include projected losses. The Company performed this evaluation for the non-Agency MBS in an unrealized loss position and has determined that there have not been any adverse changes in the timing or amount of estimated future cash flows that necessitate a recognition of OTTI amounts as of March 31, 2015 or December 31, 2014.

(amounts in thousands except share and per share data)

As of March 31, 2015, the Company had repurchase agreement amounts outstanding with 20 of its 33 available counterparties. The Company's counterparties, as set forth in the master repurchase agreement with the counterparty, require the Company to comply with various customary operating and financial covenants, including, but not limited to, minimum net worth, maximum declines in net worth in a given period, and maximum leverage requirements as well as maintaining the Company's REIT status. In addition, some of the agreements contain cross default features, whereby default under an agreement with one lender simultaneously causes default under agreements with other lenders. To the extent that the Company fails to comply with the covenants contained in these financing agreements or is otherwise found to be in default under the terms of such agreements, the counterparty has the right to accelerate amounts due under the master repurchase agreement. The Company was in compliance with all covenants as of March 31, 2015.

Please see Note 5 for the Company's disclosures related to offsetting assets and liabilities.

NOTE 4 – DERIVATIVES

     The Company utilizes derivative instruments to economically hedge a portion of its exposure to market risks, primarily interest rate risk. The Company primarily uses pay-fixed interest rate swaps and Eurodollar contracts to hedge its exposure to changes in interest rates and uses receive-fixed interest rate swaps to offset a portion of its pay-fixed interest rate swaps in order to manage its overall hedge position. The objective of the Company's risk management strategy is to mitigate declines in book value resulting from fluctuations in the fair value of the Company's assets from changing interest rates and to protect the Company's earnings from rising interest rates. Please refer to Note 1 for information related to the Company's accounting policy for its derivative instruments.

Effective June 30, 2013, the Company de-designated certain interest rate swap agreements as cash flow hedges under ASC Topic 815. There is a net unrealized loss of $1,520 remaining in AOCI on the Company's consolidated balance sheet as of March 31, 2015 which represents the activity related to these interest rate swap agreements while they were previously designated as cash flow hedges, and this amount will be recognized in the Company's net income as a portion of "interest expense" over the remaining contractual life of the agreements. The Company estimates the portion of existing net unrealized loss on discontinued cash flow hedges expected to be reclassified to net income within the next 12 months is $2,429.

Many of the Company's interest rate swaps were entered into under bilateral agreements which contain various covenants related to the Company’s credit risk. Specifically, if the Company defaults on any of its indebtedness, including those circumstances whereby repayment of the indebtedness has not yet been accelerated by the lender, or is declared in default of any of its covenants with any counterparty, then the Company could also be declared in default under the bilateral agreement. Additionally, these agreements allow those counterparties to require settlement of its outstanding derivative transactions if the Company fails to earn net income excluding derivative gains and losses greater than one dollar as measured on a rolling two quarter basis. These interest

rate agreements also contain provisions whereby, if the Company fails to maintain a minimum net amount of shareholders’ equity, then the Company may be declared in default on its derivative obligations. The Company was in compliance with all covenants under bilateral agreements on March 31, 2015.

Please see Note 5 for the Company's disclosures related to offsetting assets and liabilities.

NOTE 5 – OFFSETTING ASSETS AND LIABILITIES

NOTE 6 – FAIR VALUE OF FINANCIAL INSTRUMENTS

ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 clarifies that fair value should be based on the assumptions market participants would use when pricing an asset or liability and also requires an entity to consider all aspects of nonperformance risk, including the entity's own credit standing, when measuring fair value of a liability. ASC Topic 820 established a valuation hierarchy of three levels as follows:

• Level 1 – Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities as of the measurement date.

• Level 2 – Inputs include quoted prices in active markets for similar assets or liabilities; quoted prices in inactive markets for identical or similar assets or liabilities; or inputs either directly observable or indirectly observable through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.  

• Level 3 – Unobservable inputs are supported by little or no market activity. The unobservable inputs represent management’s best estimate of how market participants would price the asset or liability at the measurement date.  Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.  

The following table presents the fair value of the Company’s assets and liabilities presented on its consolidated balance sheets, segregated by the hierarchy level of the fair value estimate, that are measured at fair value on a recurring basis as of the dates indicated:

The Company did not have assets or liabilities measured at fair value on a non-recurring basis as of March 31, 2015 or December 31, 2014.

The Company's derivative assets and liabilities include interest rate swaps and Eurodollar futures. Interest rate swaps are valued using the income approach with the primary input being the forward interest rate swap curve, which is considered an observable input and thus their fair values are considered Level 2 measurements. Eurodollar futures are valued based on closing exchange prices on these contracts. Accordingly, these financial futures are classified as Level 1.

Agency MBS, as well a majority of non-Agency MBS, are substantially similar to securities that either are currently actively traded or have been recently traded in their respective market. Their fair values are derived from an average of multiple dealer quotes and thus are considered Level 2 fair value measurements. The Company’s remaining non-Agency MBS are comprised of securities for which there are not substantially similar securities that trade frequently, and their fair values are therefore considered Level 3 measurements. The Company determines the fair value of its Level 3 securities by discounting the estimated future cash flows derived from cash flow models using assumptions that are confirmed to the extent possible by third party dealers or other pricing indicators. Significant inputs into those pricing models are Level 3 in nature due to the lack of readily available market quotes. Information utilized in those pricing models include the security’s credit rating, coupon rate, estimated prepayment speeds, expected weighted average life, collateral composition, estimated future interest rates, expected credit losses, and credit enhancement as well as certain other relevant information. Significant changes in any of these inputs in isolation would result in a significantly different fair value measurement. Level 3 assets are generally most sensitive to the default rate and severity assumptions.

The table below presents information about the significant unobservable inputs used in the fair value measurement for the Company's Level 3 non-Agency CMBS and RMBS as of March 31, 2015:

	Quantitative Information about Level 3 Fair Value Measurements (1)

Except under certain limited circumstances intended to preserve the Company's REIT status, upon the occurrence of a change in control as defined in Article IIIA, Section 7(d) of the Company’s Articles of Incorporation, or to avoid the direct or indirect imposition of a penalty tax in respect of, or to protect the tax status of, any of the Company’s real estate mortgage investment conduits (“REMIC”) interests or a REMIC in which the Company may acquire an interest (as permitted by the Company’s Articles of Incorporation), the Company may not redeem the Series A Preferred Stock prior to July 31, 2017 or the Series B Preferred Stock prior to April 30, 2018. On or after these dates, at any time and from time to time, the Preferred Stock may be redeemed in whole, or in part, at the Company's option at a cash redemption price of $25.00 per share plus any accumulated and unpaid dividends. The Series A Preferred Stock pays a cumulative cash dividend equivalent to 8.50% of the $25.00 liquidation preference per share each year and the Series B Preferred Stock pays a cumulative cash dividend equivalent to 7.625% of the $25.00 liquidation preference per share each year. Because the Preferred Stock is redeemable only at the option of the issuer, it is classified as equity on the Company's consolidated balance sheet. The Company announced that it will pay its regular quarterly dividends on its Preferred Stock for the first quarter on April 15, 2015 to shareholders of record as of April 1, 2015.

EXECUTIVE OVERVIEW

Company Overview

We are an internally managed mortgage real estate investment trust, or mortgage REIT, which invests in residential and commercial mortgage securities on a leveraged basis. Our common stock is traded on the New York Stock Exchange ("NYSE") under the symbol "DX". We also have two series of preferred stock outstanding, our 8.50% Series A Cumulative Redeemable Preferred Stock (the "Series A Preferred Stock") which is traded on the NYSE under the symbol "DXPRA", and our 7.625% Series B Cumulative Redeemable Preferred Stock (the "Series B Preferred Stock") which is traded on the NYSE under the symbol "DXPRB". Our objective is to provide attractive risk-adjusted returns to our shareholders over the long term that are reflective of a leveraged, high quality fixed income portfolio with a focus on capital preservation. We seek to provide returns to our shareholders primarily through regular quarterly dividends and also through capital appreciation.

We were formed in 1987 and commenced operations in 1988. From our inception through 2000, our operations largely consisted of originating and securitizing various types of loans, principally single-family and commercial mortgage loans and manufactured housing loans. Since 2000, we have been investing in Agency and non-Agency mortgage-backed securities (“MBS”) and are no longer originating or securitizing mortgage loans. MBS consist of residential MBS (“RMBS”) and commercial MBS (“CMBS”), including CMBS interest-only ("IO") securities. Agency MBS have a guaranty of principal payment by an agency of the U.S. government or a U.S. government-sponsored entity ("GSE") such as Fannie Mae and Freddie Mac. Non-Agency MBS have no such guaranty of payment.

Our primary source of income is net interest income, which is the excess of the interest income earned on our investments over the cost of financing these investments. We invest our capital pursuant to our Operating Policies as approved by our Board of Directors which include an Investment Policy and Investment Risk Policy. For more information see Part I, Item 1 of our Annual Report on Form 10-K for the year ended December 31, 2014 under “Company Overview - Operating Policies and Restrictions.”

RMBS. Our Agency RMBS investments include MBS collateralized by adjustable-rate mortgage loans ("ARMs"), which have interest rates that generally will adjust at least annually to an increment over a specified interest rate index, and hybrid adjustable-rate mortgage loans ("hybrid ARMs"), which are loans that have a fixed rate of interest for a specified period (typically three to ten years) and then adjust their interest rate at least annually to an increment over a specified interest rate index. Agency ARMs also include hybrid Agency ARMs that are past their fixed-rate periods or within twelve months of their initial reset period. We may also invest in fixed-rate Agency RMBS from time to time.

We also invest in non-Agency RMBS, which do not carry a principal guarantee from the U.S. government or a GSE. Non-Agency RMBS are collateralized by non-conforming residential mortgage loans and credit tranched into different classes of securities with payments to junior classes subordinate to senior classes. We generally invest in senior classes of non-Agency RMBS that are of higher credit quality and which may include unrated securities that have sufficiently high collateralization to protect our investment from most credit events.

CMBS. Our Agency and non-Agency CMBS are collateralized by first mortgage loans and are primarily fixed-rate securities but also include securities with rates that reset monthly based on an index rate, such as LIBOR. The majority of the loans

20

collateralizing our CMBS are secured by multifamily properties. Typically these loans have some form of prepayment protection provisions (such as prepayment lock-out) or prepayment compensation provisions (such as yield maintenance or prepayment penalty). Yield maintenance and prepayment penalty requirements are intended to create an economic disincentive for the loans to prepay.

CMBS IO. A portion of our Agency and non-Agency CMBS includes IO securities which represent the right to receive interest payments (but not principal cash flows) based on the unpaid principal balance of the underlying pool of mortgage loans. As these securities have no principal associated with them, the interest payments received are based on the unpaid principal balance of the underlying pool of mortgage loans, which is often referred to as the notional amount. CMBS IO securities generally have some level of prepayment protection in the form of lock-outs, prepayment penalties, or yield maintenance associated with the underlying loans similar to CMBS described above.

Factors that Affect Our Results of Operations and Financial Condition

The performance of our investment portfolio, including the amount of net interest income we earn and fluctuations in investment values, will depend on multiple factors, many of which are beyond our control. These factors include, but are not limited to, the absolute level of interest rates, changes in expectations with regard to future interest rates, the relative steepness of interest rate curves, actual and estimated future prepayment rates on our investments, competition for investments, economic conditions and their impact on the credit performance of our investments (including multifamily, residential and commercial mortgage markets), and market required yields as reflected by market credit spreads. In addition, the performance of our investment portfolio, the cost and availability of financing and the availability of investments at acceptable return levels could be influenced by actions and policy measures of the U.S. government including, but not limited to, the Federal Housing Finance Administration, the U. S. Department of the Treasury (the "Treasury"), and the Board of Governors of the Federal Reserve System (the "Federal Reserve") and could also be influenced by other central banks around the world.

Our business model may also be impacted by other factors such as the availability and cost of financing and the state of the overall credit markets. Reductions in the availability of financing for our investments could significantly impact our business and force us to sell assets that we otherwise would not sell, potentially at losses depending on market conditions. Recent regulatory developments impacting large U.S. domiciled banks and their broker dealer subsidiaries have in some instances reduced their capacity to lend. Broadly, U.S. and international regulators are seeking to force regulated financial institutions to hold more capital against their assets, including reverse repurchase agreements. We have not yet seen a reduction in the availability of financing. We also maintain a diverse set of counterparties including broker dealer subsidiaries of non-U.S. domiciled banks and independent dealers to attempt to mitigate this risk. Other factors also impacting our business include changes in regulatory requirements, including requirements to qualify for registration under the Investment Company Act of 1940, and REIT requirements.

As discussed above, investing in mortgage-related securities on a leveraged basis subjects us to a number of risks including interest rate risk, prepayment and reinvestment risk, credit risk, market value risk and liquidity risk, which are discussed in "Liquidity and Capital Resources" within this Item 2 and in Part I, Item 3 of this Quarterly Report on Form 10-Q as well as in Item 1A, "Risk Factors" of Part I, and in Item 7A, "Quantitative and Qualitative Disclosures about Market Risk" of Part II of our Annual Report on Form 10-K for the year ended December 31, 2014. Please see these Items for a detailed discussion of these risks and the potential impact on our results of operations and financial condition.

Highlights of the First Quarter of 2015 and Outlook for Second Quarter of 2015

During the first quarter of 2015, we added investments, resulting in net growth of earning assets and reversing the trend of declining balance of investments since June 30, 2013. While we continue to be concerned with potential volatility in interest rates and asset credit spreads given the uncertain global macroeconomic environment, we added assets as spreads mostly widened during the quarter. While our MBS portfolio as of March 31, 2015 increased $363.5 million since December 31, 2014, our average balance of MBS only increased $55.1 million as many of our purchases settled late in the first quarter or will settle in the second quarter of 2015. The majority of these purchases were multifamily Agency CMBS and approximately 10% were non-Agency RMBS which consisted entirely of senior tranches of non-performing loan securitizations ("NPL" securities). Senior classes of NPL securities are non-rated but have substantial credit enhancement within the securitization structure. We believe the assets we added have relatively low spread volatility (in the case of Agency CMBS) or are short-duration investments (in the case of non-Agency RMBS).

21

During the first quarter of 2015, we declared a dividend of $0.24 per common share which, coupled with a decline in book value of $0.06 per common share, resulted in an annualized economic return to shareholders of 7.98% based on December 31, 2014 book value of $9.02 per common share. Our net interest spread improved slightly to 1.93% from 1.92% for the fourth quarter of 2014. Our adjusted net interest spread, a non-GAAP measure which includes net periodic interest costs on derivatives, was relatively stable at 1.96% versus 1.97% for the fourth quarter of 2014. Future Federal Open Market Committee ("FOMC") actions, which are discussed further below, have the potential to heavily impact our adjusted net interest spread depending on our hedge position.

We continued to re-align our hedge position during the first quarter. Our objective was to generally remain neutral with respect to our overall duration exposure (a measure of our portfolio value's sensitivity to changes in interest rates) while adding duration risk further out the yield curve. For an indication of the risk to our net income and our book value per common share, see the "Interest Rate Risk" in Item 3. "Quantitative and Qualitative Disclosures about Market Risk". Subsequent to quarter end, we terminated Eurodollar futures with an aggregate notional balance of $2.0 billion expiring in the third quarter and fourth quarters of 2015 because we concluded the costs of these contracts exceeded their potential benefit at expiration.

The table below provides quarterly information on weighted average effective yields by type of investment as well as cost of funds and other information. Weighted average effective yields are derived by dividing annualized interest income by the average amortized cost of the related assets, and cost of funds are derived by dividing annualized interest expense by the daily average balance of the related liabilities.

As we move into the second quarter and remainder of 2015, we expect to continue making opportunistic investments in order to grow our balance sheet while continuing to maintain a disciplined focus on our risk position. We anticipate continuing to focus on multifamily Agency CMBS, Agency and non-Agency CMBS IO as well as selectively investing in RMBS with an anticipated focus on re-performing and non-performing loan securitizations ("RPL/NPL securities") and Agency hybrid ARMs. We will continue to manage our financing and hedging portfolios to address the potential for increasing interest rates late in 2015 or in 2016. We have applied for membership to the Federal Home Loan Bank ("FHLB") system for a subsidiary of ours, and if approved, this will provide us an additional source of liquidity.

Trends and Recent Market Impacts

There are a number of key macroeconomic factors, conditions, and prospective trends that may impact our business. Factors, conditions, and trends that had significant developments during the first quarter of 2015 are discussed below.

22

Interest rates exhibited marked volatility during the first quarter of 2015 as markets continued to evaluate U.S. economic performance. The yield on 10-year U.S. Treasury securities began 2015 at 2.17%, but briefly rallied to 1.64% in the first few weeks of 2015 before ending the quarter at 1.92%. Since the end of the first quarter, the 10-year U.S. Treasury has continued to sell-off and stands close to its level at the beginning of the year. The rally in Treasuries during the first quarter was driven by growing sentiment that economic growth in the U.S. was decelerating given signs of slower global economic growth. U.S. interest rates also continued to be impacted by global events. In January 2015, the European Central Bank engaged in an asset purchase program similar to the quantitative easing program concluded by the Federal Reserve in 2014 in order to support the Eurozone economy, and rates there remain some of the lowest in the developed economies. We believe lower global rates and uncertainty around global economic performance and global central bank activities may ultimately keep U.S. interest rates from rising significantly.

The Federal Reserve Open Market Committee ("FOMC") continues to guide markets to anticipate an interest rate hike in 2015. As of May 1, 2015, markets are generally pricing in an increase in the Federal Funds Rate of nearly 50 basis points by the end of 2015 to 0.63% and to nearly 1.43% by the end of 2016 (both as evidenced by pricing in the Eurodollar futures markets). FOMC officials have indicated that they will take a measured approach to interest rate decisions, suggesting that changes in monetary policy will be gradual , consistent with their approach over the last several quarters. If the FOMC raises the Federal Funds Rate in 2015, we would expect our borrowing costs to rise, and therefore push down our adjusted net interest spread. In our view, global economic conditions make it difficult to predict precisely when and by how much the Federal Reserve will raise rates.

Regulatory impacts on financial institutions, many of which are our trading and financing counterparties, continue to pose a threat in our view to the overall liquidity in the capital markets. In particular, higher capital requirements under U.S. banking regulations adopted in 2013 and 2014 and the Dodd-Frank Wall Street Reform and Consumer Protection Act’s limitations on the proprietary trading activities of large U.S. financial institutions could result in reduced liquidity in times of market stress. According to industry data, large U.S. financial institutions have reduced their holdings in Agency RMBS by nearly 50% from their 2008 peak to currently $112 billion. Average daily trading volume in Agency RMBS has continued to decline as well and has fallen 43% since 2008 also, according to industry data. While the Federal Reserve continues to reinvest principal payments received on its $1.7 trillion Agency RMBS portfolio, it is unlikely that this activity will provide enough liquidity to the market in times of stress, which could result in volatile asset prices. 

CRITICAL ACCOUNTING POLICIES

The discussion and analysis of our financial condition and results of operations are based in large part upon our consolidated financial statements, which have been prepared in accordance with GAAP.  The preparation of our consolidated financial statements requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities. We base these estimates and judgments on historical experience and assumptions believed to be reasonable under current facts and circumstances. Actual results, however, may differ from the estimated amounts we have recorded. The discussion and analysis of our financial condition and results of operations also consider certain non-GAAP measures as described in "Non-GAAP Financial Measures" in this Part I, Item 2.

Critical accounting policies are defined as those that require management's most difficult, subjective or complex judgments, and which may result in materially different results under different assumptions and conditions. Our accounting policies that require the most significant management estimates, judgments, or assumptions, or that management believes includes the most significant uncertainties, and are considered most critical to our results of operations or financial position relate to fair value measurements, amortization of investment premiums, and other-than-temporary impairments. Our critical accounting policies are discussed in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the year ended December 31, 2014 under “Critical Accounting Policies”. There have been no significant changes in our critical accounting policies during the three months ended March 31, 2015.

RMBS

Our RMBS are collateralized substantially by ARMs and hybrid ARMs. Activity related to our RMBS for the three months ended March 31, 2015 is as follows:

($ in thousands)	Agency RMBS			Non-Agency RMBS			Total
Balance as of December 31, 2014	$	2,186,700		22,448			$	2,209,148

Balance as of March 31, 2015	$	2,044,880		$	76,642		$	2,121,522

Our investment in RMBS as of March 31, 2015 has decreased since December 31, 2014 as principal payments and sales have outpaced purchases. During the first quarter of 2015, we significantly increased our non-Agency RMBS portfolio by purchasing senior tranches of NPL securities with short durations ranging between one and two years. Though non-rated investments, these assets have substantial credit enhancement within the securitization structure, and we believe that they offer an attractive return profile with relatively stable cash flows. These non-Agency RMBS were purchased at or near par and yielded 3.62% on average for the first quarter of 2015. Sales of Agency RMBS consisted of certain lower yielding Agency ARMs that were at or near their interest rate reset periods and in unrealized loss positions. We sold these Agency ARMs, because we concluded the potential for additional loss exceeded the incremental income we would earn from holding those positions.

As of March 31, 2015, approximately 97% of our variable-rate Agency RMBS portfolio resets based on one-year LIBOR. The following table presents the reset margin and weighted average coupon (“WAC”) by weighted average months to reset ("MTR") for the variable-rate portion of our Agency RMBS portfolio based on par value as of the dates indicated:

Total	$	1,942,332			3.08	%	$	2,086,807			3.09	%

The rate at which we amortize the premiums we pay for our investments is impacted by the current and forecasted constant prepayment rate ("CPR"). Prepayments on our Agency RMBS remain below projections, and this resulted in a net positive amortization adjustment of $0.8 million during the first quarter of 2015. The following table provides the CPRs on our Agency RMBS for the periods indicated:

	Three Months Ended
	March 31, 2015		December 31, 2014		September 30, 2014		June 30, 2014		March 31, 2014
Agency RMBS	12.4	%	12.5	%	15.3	%	14.1	%	12.7	%

CMBS

Our Agency CMBS are collateralized primarily by fixed rate mortgage loans secured by multifamily properties. Our non-Agency CMBS are collateralized by fixed rate mortgage loans secured by income producing properties such as office, retail, hotel, and multifamily. Both Agency and non-Agency CMBS will generally have some form of prepayment protection provisions (such as prepayment lock-outs) or prepayment compensation provisions (such as yield maintenance or prepayment penalties) to prevent early voluntary prepayment of principal.

Activity related to our CMBS for the three months ended March 31, 2015 is as follows:

($ in thousands)	Agency CMBS			Non-Agency CMBS			Total
Balance as of December 31, 2014	$	335,197		$	208,038		$	543,235
Purchases	444,218			12,999			457,217

Balance as of March 31, 2015	$	777,747		$	216,265		$	994,012

Our CMBS portfolio increased approximately 83% during the first quarter of 2015 primarily due to purchases of Agency CMBS, the majority of which are recently issued securities backed by loans on multi-family properties. These securities had a weighted average purchase price near par and a weighted average yield of 2.49% for the first quarter of 2015. In the current low yield environment, these bonds offer us compelling risk-adjusted returns because they have limited prepayment risk, limited extension risk, stable cash flow, and lower spread risk. The non-Agency CMBS purchased during the three months ended March 31, 2015 was for one investment near its par value of $13.0 million.

The geographic diversification of the collateral underlying our non-Agency CMBS has not changed significantly since December 31, 2014.

CMBS IO

The majority of our CMBS IO investments are collateralized primarily by fixed rate mortgage loans. Agency CMBS IO are exclusively collateralized by multifamily properties and non-Agency CMBS IO are secured by income producing properties such as office, retail, and hotel. Both types of CMBS IO have some form of prepayment protection (such as prepayment lock-outs) or prepayment compensation provisions (such as yield maintenance or prepayment penalties). Our CMBS IO investments are investment grade-rated with the majority rated 'AAA' by at least one of the nationally recognized statistical ratings organizations.

Activity related to our CMBS IO for the three months ended March 31, 2015 is as follows:

($ in thousands)	Agency CMBS IO (1)			Non-Agency CMBS IO (1)			Total

Derivative Assets and Liabilities

Our derivative assets and liabilities consist of interest rate swap agreements and Eurodollar futures, which we use to hedge our earnings and book value exposure to fluctuations in interest rates. Eurodollar futures represent forward starting 3-month LIBOR contracts and allow us to synthetically replicate swap curves and/or hedge specific points on the swap curve where we may have duration risk by shorting contracts at various points of the LIBOR curve. We use both pay-fixed and receive-fixed interest rate swaps to manage our overall hedge position. As of March 31, 2015, the weighted average notional amount of interest rate derivatives that will be effective for future periods are shown in the following table:

Effective Period	Pay-Fixed Interest Rate Swaps		Pay-Fixed Weighted Average Rate (1)		Receive-Fixed Interest Rate Swaps		Receive-Fixed Weighted Average Rate (1)		Eurodollar Futures		Eurodollar Futures Weighted-Average Rate (1)

(1) Weighted average rate is based on the weighted average notional outstanding.

Because we increased our repurchase agreement borrowings to finance our investment purchases during the first quarter of 2015, the Company added interest rate swaps with a combined notional amount of $815.0 million and a weighted average pay-fixed rate of 1.88%, of which $425.0 million are forward-starting. The Company also terminated $205.0 million of interest rate

27

swaps with a weighted average pay-fixed rate of 2.14%, resulting in a realized loss of ($5.7) million. Subsequent to March 31, 2015, we terminated Eurodollar futures included in the table above with a combined notional amount of $2.0 billion and a weighted average rate of 0.93%, realizing a cumulative loss of ($168) which will be recognized within "loss on derivative instruments, net" on our comprehensive income statement for the three and six months ended June 30, 2015. Please refer to Note 4 of the Notes to the Unaudited Consolidated Financial Statements contained in Part I, Item 1, “Financial Statements” of this Quarterly Report on Form 10-Q as well as "Loss on Derivative Instruments, Net" within "Results of Operations" contained within this Part 1, Item 2 for additional information related to our derivative assets and liabilities.

Repurchase Agreements

Our repurchase agreement borrowings increased a net $172.7 million from December 31, 2014 to March 31, 2015 in order to partially finance our MBS purchases of $583.1 million during the first quarter of 2015. Approximately $197.4 million of the MBS purchases were pending settlement for which we had a corresponding payable of $196.5 million as of March 31, 2015. The combined weighted average original term to maturity for the Company’s repurchase agreements was 116 days as of March 31, 2015 compared to 144 days as of December 31, 2014. Given the favorable financing environment during the first quarter of 2015, we rolled a substantial portion of our repurchase agreements that matured during the quarter to repurchase agreements with 30-90 day maturities versus original maturities of 91-180 days.

The following table presents the amount pledged and leverage against the fair value of our non-Agency MBS investments by credit rating as of March 31, 2015 and December 31, 2014:

RESULTS OF OPERATIONS

This section of our Quarterly Report on Form 10-Q includes non-GAAP financial measures which exclude certain GAAP items. Please read the section "Non-GAAP Financial Measures" contained at the end of this section for additional important information.

Comprehensive income to common shareholders for the three months ended March 31, 2015 decreased $15.2 million compared to the three months ended March 31, 2014, primarily as a result of a net decrease in the fair value of our derivative instruments of $13.3 million. In addition, interest income for the three months ended March 31, 2015 decreased $3.5 million compared to the same period in 2014, primarily as a result of a smaller investment portfolio earning lower average effective yields. These unfavorable decreases were partially offset by a decrease in interest expense from our repurchase agreement borrowings of $0.9 million and lower net periodic interest costs of derivative instruments of $1.3 million. The discussions that follow provide more information on these items as well as others on the consolidated statements of comprehensive income.

Interest Income and Asset Yields

Interest income includes gross interest earned from the coupon rate on the securities, effects of premium amortization and discount accretion, and other interest income resulting from prepayment penalty income or other yield maintenance items. The following table presents information regarding interest income earned and effective yield on our MBS by collateral type for the periods indicated:

(1) Average balances are calculated as a simple average of the daily amortized cost and exclude unrealized gains and losses as well as securities pending settlement if applicable.

(2) Effective yields are weighted by average balance of the investments and based on annualized amounts. Recalculation of effective yields may not be possible using data provided because certain components of interest income use a 360-day year for the calculation while others use actual number of days in the year.

The following table presents the estimated impact of changes in average balances and average yields on interest income for the periods indicated:

(1) Average balances are calculated as a simple average of the daily amortized cost and exclude unrealized gains and losses as well as securities pending settlement if applicable.

Interest income for the three months ended March 31, 2015 decreased compared to the same period in 2014 because of the decline in the average balance of our portfolio and the lower weighted average effective yield overall. Over the past twelve months, we received $424.1 million of principal payments and sold $147.0 million of Agency RMBS. Substantially all of the proceeds received from payments and sales were invested in CMBS and CMBS IO where we have seen better risk adjusted returns over the last twelve months.

Our Agency CMBS average balance was higher during the first quarter of 2015 compared to the same period in 2014, because we made purchases of Agency CMBS of $444.2 million during the first quarter of 2015. Because these purchases were primarily recently issued securities, they were acquired at close to their par values and have yields similar to their stated coupons. The lower average yields on the securities purchased during the first quarter of 2015 lowered our weighted average effective yield on Agency CMBS for the first quarter of 2015 to 3.30% from 3.52% for the same period in 2014. In addition, $196.1 million of our Agency CMBS purchases during the first quarter of 2015 had not settled as of the end of the reporting period and therefore had no impact on our interest income for the first quarter of 2015. Our non-Agency CMBS average balance decreased since the first quarter of 2014 due to the sale of certain securities during the second half of 2014, which we sold to reduce our exposure to the risk of credit spreads widening on those assets. The non-Agency CMBS investments we purchased have been newer issue securities and/or floating rate securities which were acquired at or near their par values. The lower yield on our purchases and the non-Agency CMBS sales lowered our weighted average effective yield on this portion of our portfolio for the first quarter of 2015 to 4.51% from 5.56% for the same period in 2014.

Similarly, purchases of CMBS IO since the first quarter of 2014 have generally been at lower yields than the CMBS IO yield as of March 31, 2014 resulting in a decline in the overall weighted average effective yield to 3.83% for the first quarter of 2015 from 4.21% for the comparative period in 2014. Over the past twelve months, we have purchased $187.2 million in non-Agency CMBS IO, increasing our average balance and interest income for that portion of the portfolio for the first quarter of 2015 compared to the same period in 2014. Although our purchases of Agency CMBS IO have outpaced our sales over the past twelve months, our average balance has decreased due to the premium amortization.

The following table presents the estimated impact of changes in the average balance of repurchase agreement borrowings and average borrowing rates on the decrease in interest expense for the comparative periods presented:

	Three Months Ended
	March 31, 2015 vs. March 31, 2014
				Due to Change in
($ in thousands)	Decrease in Interest Expense			Average Balance			Average Borrowing Rate
Repurchase agreements	$	(1,035	)	$	(603	)	$	(432	)

Our average balances of repurchase agreement borrowings were lower for the three months ended March 31, 2015 compared to the same period in 2014 due to the lower average balance of our investment portfolio for the three months ended March 31, 2015 versus the same period in 2014. Our repurchase agreement borrowing rates were also lower for three months ended March 31, 2015 compared to the same period in 2014 because of the tighter spread environment, the continuing low interest rate environment, and the ample liquidity in the financing markets that has increased competition among our repurchase agreement counterparties relative to the same period in 2014.

Because we use derivative instruments as economic hedges of our interest rate risk exposure, management considers net periodic interest costs from effective derivative instruments to be an additional cost of financing investments. As such, management utilizes a non-GAAP financial measure "effective borrowing cost" which includes the net periodic interest costs of our effective derivative instruments excluded from GAAP interest expense. The table below presents a reconciliation of GAAP interest expense and cost of funds to our effective borrowing cost and rate for the periods indicated:

	Three Months Ended
	March 31,
	2015					2014
($ in thousands)	Amount			Rate		Amount			Rate
GAAP interest expense/cost of funds	$	5,371		0.69	%	$	7,633		0.87	%
Amortization of de-designated cash flow hedges (1)	(1,057		)	(0.14	)%	(2,288		)	(0.26	)%
Net periodic interest costs of derivative instruments	862			0.11	%	2,211			0.25	%
Effective borrowing cost/rate	$	5,176		0.66	%	$	7,556		0.86	%

31

(1) Amount recorded as a portion of "interest expense" in accordance with GAAP and is related to the amortization of the balance in accumulated other comprehensive loss as of June 30, 2013 related to the derivatives for which we discontinued cash flow hedge accounting.

Our net periodic interest costs of derivative instruments were lower for the three months ended March 31, 2015, because we held a lower net average notional balance at a lower net pay-fixed rate compared to the same period in 2014. In addition, as discussed above, our average borrowings were lower for the first quarter of 2015 versus the same period in 2014 and had lower interest costs.

Net Interest Income and Net Interest Spread

The tables below present net interest income and related net interest spread pursuant to GAAP, and also present the non-GAAP measures "adjusted net interest income" and "adjusted net interest spread" for the periods indicated. "Adjusted net interest income" and "adjusted net interest spread" are calculated using the non-GAAP measure "effective borrowing cost" reconciled in the table above, and therefore include net periodic interest cost of derivative instruments whereas GAAP net interest income and GAAP net interest spread do not.

Average balance of borrowings (3)	$	3,111,783				$	3,509,889

(1) Amount recorded as a portion of "interest expense" in accordance with GAAP related to the amortization of the balance remaining in accumulated other comprehensive loss as of June 30, 2013 as a result of our discontinuation of cash flow hedge accounting.

(2) Average balances are calculated as a simple average of the daily amortized cost and exclude unrealized gains and losses as well as securities pending settlement if applicable.

(3) Average balances are calculated as a simple average of the daily borrowings outstanding for both repurchase agreement and non-recourse collateralized financing.

Net interest income and adjusted net interest income for the three months ended March 31, 2015 decreased compared to the same period in 2014 due to the lower average balance of interest-earnings assets that were also earning lower weighted average effective yields. Net interest spread and adjusted net interest spread for the three months ended March 31, 2015, however, increased relative to the same period in 2014, because the decrease in our cost of funds and effective borrowing rate more than offset the lower weighted average effective yield.

Loss on Derivative Instruments, Net

For the three months ended March 31, 2015, $(5.7) million of the $(24.5) million change in fair value represents realized losses from our termination of interest rate swaps with a combined notional amount of $205.0 million and a weighted average pay-fixed rate of 2.14%.

Loss on derivative instruments, net for the three months ended March 31, 2015 increased by $11.9 million compared to the same period in 2014, principally as a result of the shifts in the yield curve during the first quarter of 2015.

General and Administrative Expenses

General and administrative expenses were $4.3 million for the three months endedMarch 31, 2015 compared to $4.1 million for the three months endedMarch 31, 2014. Compensation and benefits expenses decreased due to lower bonus expenses while other general and administrative expenses increased primarily due to increased legal expenses.

Non-GAAP Financial Measures

In addition to our operating results presented in accordance with GAAP, this Quarterly Report on Form 10-Q contains certain non-GAAP financial measures. Management presents certain of this information because net income (loss) includes material fair value adjustments on our derivatives but does not include corresponding fair value adjustments on investments. In addition, net interest income and net interest spread exclude the net periodic costs of our derivative instruments. Management believes these non-GAAP measures coupled with the GAAP measures more clearly explain our performance from period to period. Management uses these measures in its internal analysis of financial and operating performance and believes that it provides better transparency

33

to our investors of management's view of our economic performance. Management also believes the presentation of these measures, when analyzed in conjunction with the Company's GAAP operating results, allows investors to more effectively evaluate and compare our performance to that of our peers even though peer companies may present its non-GAAP measures on a different basis than we do. Because these non-GAAP financial measures exclude certain items used to compute GAAP net income to common shareholders and GAAP interest expense, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, our GAAP results as reported on the consolidated statements of comprehensive income. In addition, because not all companies use identical calculations, our presentation of core net operating income, effective borrowing cost and rate, adjusted net interest income, and adjusted net interest spread may not be comparable to other similarly-titled measures of other companies.

Schedules reconciling effective borrowing cost, adjusted net interest income, and adjusted net interest spread to their related GAAP financial measures are provided within "Results of Operations" within Part 1, Item 2 of this Quarterly Report on Form 10-Q. The following table presents a reconciliation of our GAAP net income (loss) to our core net operating income for the periods presented:

LIQUIDITY AND CAPITAL RESOURCES

 Our primary sources of liquidity include borrowings under repurchase arrangements, monthly principal and interest payments we receive on our investments, unencumbered Agency MBS, and unencumbered cash. Additional sources may also include proceeds from the sale of investments, unencumbered non-Agency MBS, equity offerings, issuances of collateralized financings, and payments received from counterparties from interest rate swap agreements. We use our liquidity to fund our investment purchases and other operating costs, to pay down borrowings, to make payments to counterparties as required under interest rate swap agreements, and to pay dividends on our common stock.

Our available liquid assets as of March 31, 2015 were $182.5 million compared to $215.8 million as of December 31, 2014. As of March 31, 2015, our liquid assets consisted of unrestricted cash and cash equivalents of $38.5 million and unencumbered Agency MBS of $144.0 million, which we may pledge to lenders and derivative counterparties if we experience a margin call (discussed further below). In addition, we may pledge unencumbered non-Agency MBS to lenders as collateral for margin calls, but we consider these assets to be less liquid than Agency MBS because they are less likely to be accepted as collateral by lenders during periods of market stress. Our unencumbered non-Agency MBS was $66.9 million as of March 31, 2015.

We continually monitor our current and forecasted available liquidity. Our liquid assets may fluctuate from period to period based on our investment activities and whether we have recently raised, but not yet deployed, equity capital. However, we seek to maintain sufficient liquidity based on the sensitivity analysis and debt-to-equity requirements discussed below, to support our operations and meet our anticipated liquidity needs.

We perform sensitivity analysis on our liquidity based on changes in the value of our investments due to changes in interest rates, credit spreads, lender haircuts and prepayment speeds. We also closely monitor our debt-to-invested equity ratio (which is the ratio of debt financing to invested equity for any investment) as part of our liquidity management process as well as our overall enterprise level debt-to-equity. We also monitor the ratio of our available liquidity to outstanding repurchase agreement borrowings, which fluctuates due to changes in the fair value of collateral we have pledged to our lenders. On an enterprise level

34

basis, our current operating policies limit our total liabilities-to-shareholders' equity to seven (7) times our shareholders' equity. At the individual investment level, our targeted leverage ranges from three (3) to ten (10) times our invested equity capital depending on the investment type. The maximum targets represent fixed limits for leveraging our investment capital. We may change our leverage targets based on market conditions and our perceptions of the liquidity of our investments.

On an enterprise-wide basis, our total liabilities increased to 5.7 times shareholders' equity as of March 31, 2015 from 5.1 times as of December 31, 2014 due to our use of repurchase agreement borrowings to partially finance investment purchases during the first quarter of 2015. Excluding the payable for unsettled securities, our ratio of total liabilities to shareholders' equity would have been 5.4 times shareholders' equity. At this time, we do not expect our leverage to increase significantly for the remainder of 2015.

We have historically had ample sources of liquidity to fund our activities and operations. The ability to fund our operations in the future depends in large measure on the availability of credit through repurchase agreement financing and the liquidity of our investments. Credit markets in general are stable, and currently there is ample availability. However, these markets and the liquidity of our investments remain susceptible to extreme market volatility as was experienced in 2008 and 2009. In addition, in recent quarters U.S. financial regulatory agencies (such as the Office of Financial Research in the U.S. Treasury and the Federal Reserve) have expressed some concern about the stability of repurchase agreement financing for mortgage REITs in a rising interest rate environment, and regulatory reform in the form of certain provisions of the Basel III capital framework (and supplemental bank capital rules) and the Dodd-Frank Wall Street Reform and Consumer Protection Act could impact the overall availability of credit by restricting the number of repurchase agreement lenders and the credit made available by such lenders. In times of severe market stress, repurchase agreement availability could be rapidly reduced and the terms on which we can borrow could be materially altered, particularly given the focus on these markets by the federal financial and banking regulators. Competition from other REITs, banks, hedge funds, and the federal government for capacity with our repurchase agreement lenders could also reduce our repurchase agreement availability. While we do not anticipate such events in the near term, a reduction in our borrowing capacity could force us to sell assets in order to repay our lenders or could otherwise restrict our ability to operate our business.

Depending on our liquidity levels, the condition of the credit markets, and other factors, we may from time to time consider the issuance of debt, equity, or other securities, or sell investments, the proceeds of which could provide additional liquidity for our operations. While we will attempt to avoid dilutive or otherwise costly issuances, depending on market conditions, in order to manage our liquidity we could be forced to issue equity or debt securities which are dilutive to our capital base or our profitability.

Repurchase Agreements

The following table presents information regarding the balances of our repurchase agreement borrowings for the periods indicated:

($ in thousands)	Balance Outstanding As of Quarter End		Average Balance Outstanding For the Quarter Ended		Maximum Balance Outstanding During the Quarter Ended
March 31, 2015	$	3,185,843	$	3,101,133	$	3,239,247
December 31, 2014	3,013,110		3,043,298		3,137,204
September 30, 2014	3,150,254		3,352,599		3,469,491
June 30, 2014	3,447,050		3,454,884		3,496,521
March 31, 2014	3,485,544		3,497,167		3,580,997

Our leverage increased during the first quarter of 2015 as we used repurchase agreement borrowings to partially finance investment opportunities we identified within the Agency CMBS and non-Agency RMBS market.

We manage the maturities of our repurchase agreements based on market conditions. The weighted average original term to maturity for our repurchase agreement borrowings was 116 days as of March 31, 2015 compared to 144 days as of December 31, 2014. We have recently begun to extend our maturities further into 2015 and 2016 as we seek to lock-in lower borrowing rates. We expect borrowing rates to increase as repurchase agreement availability is reduced due to regulatory constraints on our lenders and on financial institutions that provide funding and liquidity to our lenders.

     Our repurchase agreement borrowings are generally renewable at the discretion of our lenders without guaranteed roll-over terms. Given the short-term and uncommitted nature of most of our repurchase agreement financing, we attempt to maintain unused capacity under our existing repurchase agreement credit lines with multiple counterparties which helps protect us in the

35

event of a counterparty's failure to renew existing repurchase agreements either with favorable terms or at all. As of March 31, 2015, we had repurchase agreement borrowings outstanding with 20 of our 33 available repurchase agreement counterparties at a weighted average borrowing rate of 0.56% compared to0.55% as of December 31, 2014. Our repurchase agreement borrowings generally carry a rate of interest based on a spread to an index such as LIBOR.

For our repurchase agreement borrowings, we are required to post and maintain margin to the lender (i.e., collateral in excess of the repurchase agreement financing) in order to support the amount of the financing. This excess collateral is often referred to as a "haircut" (and which we also refer to as equity at risk). As the collateral pledged is generally MBS, the fair value of the collateral can fluctuate with changes in market conditions. If the fair value of the collateral falls below the haircut required by the lender, the lender has the right to demand additional margin, or collateral, to increase the haircut back to the initial amount. These demands are typically referred to as "margin calls". Declines in the value of investments occur for any number of reasons including but not limited to changes in interest rates, changes in ratings on an investment, changes in actual or perceived liquidity of the investment, or changes in overall market risk perceptions. Additionally, values in Agency RMBS will also decline from the payment delay feature of those securities. Agency RMBS have a payment delay feature whereby Fannie Mae and Freddie Mac announce principal payments on Agency RMBS but do not remit the actual principal payments and interest for 20 days in the case of Fannie Mae and 40 days in the case of Freddie Mac. Because these securities are financed with repurchase agreements, the repurchase agreement lender generally makes a margin call for an amount equal to the product of their advance rate on the repurchase agreement and the announced principal payments on the Agency RMBS. This causes a temporary use of our liquidity to meet the margin call until we receive the principal payments and interest 20 to 40 days later. 

The following table presents the weighted average minimum haircut contractually required by our counterparties for Agency and non-Agency MBS pledged as collateral for our repurchase agreement borrowings as of the dates indicated:

	March 31, 2015		December 31, 2014		September 30, 2014		June 30, 2014		March 31, 2014
Agency MBS	6.6	%	6.8	%	6.8	%	6.6	%	6.9	%
Non-Agency MBS	15.9	%	16.0	%	16.9	%	18.5	%	19.8	%

The counterparties with whom we have the greatest amounts of equity at risk may vary significantly during any given period due to the short-term and generally uncommitted nature of the repurchase agreement borrowings. Equity at risk is defined as the amount pledged as collateral to the repurchase agreement counterparty in excess of the repurchase agreement amount outstanding. The following tables present the five counterparties with whom we had the greatest amounts of equity at risk as of March 31, 2015 and as of December 31, 2014:

	March 31, 2015
($ in thousands)	Amount Outstanding		Equity at Risk
Well Fargo Bank, N.A. and affiliates	$	295,238	$	49,889
JP Morgan Securities, LLC	315,210		49,018
South Street Financial Corporation	566,534		35,362

The following table discloses our repurchase agreement amounts outstanding and the value of the related collateral pledged by geographic region of our counterparties as of March 31, 2015:

($ in thousands)	Amount Outstanding		Market Value of Collateral Pledged
North America	$	1,938,159	$	2,131,415
Asia	693,481		734,553
Europe	554,203		612,173
	$	3,185,843	$	3,478,141

Our repurchase agreement counterparties require us to comply with various operating and financial covenants. The financial covenants include requirements that we maintain minimum shareholders' equity (usually a set minimum, or a percentage of the highest amount of shareholders' equity since the date of the agreement), maximum decline in shareholders' equity (expressed as a percentage decline in any given period), and limits on maximum leverage (as a multiple of shareholders' equity). Operating requirements include, among other things, requirements to maintain our status as a REIT and to maintain our listing on the NYSE. Violations of one or more of these covenants could result in the lender declaring an event of default which would result in the termination of the repurchase agreement and immediate acceleration of amounts due thereunder. In addition, some of the agreements contain cross default features, whereby default with one lender simultaneously causes default under agreements with other lenders. Violations could also restrict us from paying dividends or engaging in other transactions that are necessary for us to maintain our REIT status.

We monitor and evaluate on an ongoing basis the impact these customary financial covenants may have on our operating and financing flexibility. Currently, we do not believe we are subject to any covenants that materially restrict our financing flexibility. We have one repurchase agreement lender which requires that we maintain our enterprise level leverage as of quarter end at less than 7 times our shareholders' equity.

Derivatives

Our interest rate derivative instruments require us to post initial margin at inception and variation margin based on subsequent changes in the fair value of the derivatives. The collateral posted as margin by us is typically in the form of cash or Agency MBS. Generally, as interest rates decline due to market changes, we will be required to post collateral with counterparties on our pay-fixed derivative instruments and receive collateral from our counterparties on our receive-fixed derivative instruments, and vice versa as interest rates increase. As of March 31, 2015, we had Agency MBS with a fair value of $3.6 million and cash of $67.0 million posted as credit support under these agreements.

Dividends

As a REIT, we are required to distribute to our shareholders amounts equal to at least 90% of our REIT taxable income for each taxable year after consideration of our tax NOL carryforwards. We generally fund our dividend distributions through our cash flows from operations. If we make dividend distributions in excess of our operating cash flows during the period, whether for purposes of meeting our REIT distribution requirements or other strategic reasons, those distributions are generally funded either through our existing cash balances or through the return of principal from our investments (either through repayment or sale). Our estimated NOL carryfoward available as of December 31, 2014 is approximately $90.0 million. This balance reflects the $26.4 million of the NOL that we expect to utilize for the 2014 tax year and an adjustment to the NOL balance for amendment to prior years' returns.

Contractual Obligations

The following table summarizes our contractual obligations by payment due date as of March 31, 2015:

37

($ in thousands)	Payments due by period
Contractual Obligations:	Total		< 1 year		1-3 years		3-5 years		> 5 years
Repurchase agreements (1)	$	3,187,932	$	3,187,932	$	—	$	—	$	—
Non-recourse collateralized financing (2)	10,365		2,713		3,651		2,086		1,915
Operating lease obligations	984		99		202		208		475
Total	$	3,199,281	$	3,190,744	$	3,853	$	2,294	$	2,390

(1) Includes estimated interest payments calculated using interest rates in effect as of March 31, 2015.

(2) Amounts shown are for principal only and exclude interest obligations as those amounts are not significant. Non-recourse collateralized financing represents securitization financing that is payable solely from loans and securities pledged as collateral. Payments due by period were estimated based on the principal repayments forecasted for the underlying loans and securities, substantially all of which is used to repay the associated financing outstanding.

Other Matters

As of March 31, 2015, we do not believe that any off-balance sheet arrangements exist that are reasonably likely to have a material effect on our current or future financial condition, results of operations, or liquidity. In addition, we do not have any material commitments for capital expenditures and have not obtained any commitments for funds to fulfill any capital obligations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We seek to manage various risks inherent in our business strategy, which include interest rate, prepayment, reinvestment, market value, credit, and liquidity risks. These risks can and do cause fluctuations in our book value per common share and comprehensive income. We attempt to manage these risks and earn an acceptable return for our shareholders as discussed below.

Interest Rate Risk

Investing in interest-rate sensitive investments on a leveraged basis subjects our results to interest rate risk primarily from the mismatch between interest-rate reset dates (or maturity) of our assets and the maturity of our liabilities. Borrowing costs on our liabilities are generally based on prevailing market rates and reset more frequently than interest rates on our assets. During a period of rising interest rates (particularly short term rates in a flattening yield curve environment), our borrowing costs will increase faster than our asset yields, negatively impacting our net interest income. The amount of the impact will depend on the composition of portfolio and on the effectiveness of our hedge instruments at the time, as well as the magnitude and the duration of the increase in interest rates. In addition, our adjustable rate assets may have limits or caps on the amount that an interest rate may reset while our liabilities do not have rate reset caps. Changes in interest rates, particularly rapid changes, may also negatively impact the market value of our investments which reduces our book value. In addition to the information set forth in the tables below, see "Market Value Risk" below for further discussion of the risks to the market value of our investments.

While having interest rate risk is a basic tenet of our investment strategy, we attempt to manage our exposure to changes in interest rates by investing in instruments that have short maturities/interest reset dates, entering into hedging transactions (such as interest rate swaps and Eurodollar futures) and by managing our investment portfolio within interest rate risk tolerances set by our Board of Directors. Our current goal is to maintain a net portfolio duration (a measure of interest rate risk) within a range of 0.5 to 1.5 years. Our portfolio duration may drift outside of our target range at various times due to changes in market conditions, changes in actual or expected prepayment rates on our investments, changes in interest rates, changes in credit spreads, and activity in our investment portfolio. In addition, duration is driven by model inputs, and in the case of Agency RMBS, the most important inputs include anticipated prepayment speeds. Estimates of prepayment speeds can vary significantly by investor for the same security and therefore estimates of security and portfolio duration can vary significantly.

Effect of Changes in Interest Rates on Adjusted Net Interest Income and Market Value. The table below shows the projected sensitivity of our adjusted net interest income and the market value of our investments and derivative instruments carried at fair value as they existed as of March 31, 2015 based on an instantaneous parallel shift in market interest rates as set forth in the table below. In light of the low interest rate environment at March 31, 2015, and because we believe it is unlikely that absolute rates will move lower from rates at March 31, 2015, the only declining rate scenario that we present is a downward shift of 25 basis points. In order to include the impact of changes in interest rates on our effective derivative instruments, we are presenting the percentage change in adjusted net interest income because net interest income does not include the variable interest we either receive or pay for our interest rate swap agreements which are based on certain LIBOR rates.

The "percentage change in adjusted net interest income" includes the impact of changes in expected prepayment speeds on our investments and assumes that net proceeds received from pay downs on the portfolio are reinvested in MBS in amounts proportionate to the portfolio composition that existed as of March 31, 2015 and at yields consistent with those as of that date adjusted for the parallel shift in the rates below. Changes in types of investments, future interest rates, credit spreads, the shape of the yield curve, the availability of financing, and/or the mix of our investments and financings including derivative instruments may cause actual results to differ significantly from the modeled results. There can be no assurance that assumed events used for the model below will occur, or that other events will not occur, that will affect the outcomes; therefore, the tables below and all related disclosures constitute forward-looking statements.

40

Parallel Shift in Interest Rates	Percentage change in market value (1)	Percentage change in adjusted net interest income
+100	(0.58)%	(13.90)%
+50	(0.23)%	(6.09)%
-25	0.07%	1.82%

(1) Includes changes in market value of our investments and derivative instruments, but excludes changes in market value of our financings because they are not carried at fair value on our balance sheet. The projections for market value do not assume any change in credit spreads.

Management also considers changes in the shape of the interest rate curves in assessing and managing portfolio interest rate risk. The table below shows the projected change in market value of our investment portfolio net of hedges for changes in the shape of the U.S. Treasury curve (with similar changes to the interest rate swap curve and Eurodollar curves) as of March 31, 2015.

Basis point change in  2-year yield	Basis point change in  10-year yield	Percentage change in market value
0	+25	(0.01)%
+10	+50	(0.04)%
+10	+75	(0.11)%
+25	+75	(0.09)%
+25	+0	0.04%
+50	+0	0.07%
-10	-50	(0.06)%

Our adjustable rate investments have interest rates which are predominantly based on one-year LIBOR and contain periodic (or interim) and lifetime interest rate caps which limit the amount by which the interest rate may reset on the investment. The following table presents information about the lifetime and interim interest rate caps (where interim interest rate caps include both initial adjustments of interest rates which generally are 5% as well as periodic adjustments which generally are 2%) on our adjustable-rate Agency MBS portfolio as of March 31, 2015:

Lifetime Interest Rate Caps			Interim Interest Rate Caps
	% of Total			% of Total
>7.4% to 10.0%	87.5	%	1.0%	2.2	%
>10.0% to 11.0%	8.8	%	2.0%	18.0	%
>11.0% to 12.1%	3.7	%	5.0%	79.8	%
	100.0	%		100.0	%

Market Value Risk

Market value risk generally represents the risk of loss in value of our investment securities and derivatives due to fluctuations in interest rates, prepayment rates, credit spreads, and other factors. Securities in our investment portfolio and derivative instruments are reflected at their estimated fair value on our consolidated balance sheet. Changes in the fair value of our derivative instruments are recorded within "net income" on our consolidated statement of comprehensive income while changes in the fair value of our investments are recorded within "other comprehensive income" on our consolidated statement of comprehensive income. As demonstrated in the tables above in the discussion of interest rate risk, in a rising interest rate environment, the fair value of our securities tends to decrease; conversely, in a decreasing interest rate environment, the fair value of our securities tends to increase. The fair value of our securities will also fluctuate due to changes in credit spreads (which represent the market's

41

valuation of the perceived riskiness of assets relative to risk-free rates), changes in actual prepayments or expected prepayments, the perceived liquidity of the investment, actual or expected credit performance, and other factors. We attempt to manage market value risk by managing our exposure to these factors (although we may not actively attempt to manage market value risk from changes in credit spreads). For example, the types of derivative instruments we are currently using to hedge the interest rates on our debt tend to increase in value when our investment portfolio decreases in value, although not a one-to-one correlation. 

Fluctuations in credit spreads typically vary based on the type of investments. Though market conditions and technical factors such as FOMC monetary policy may impact Agency MBS credit spreads, they will generally have less volatility than non-Agency MBS. The table below is an estimate of the projected change in our portfolio market value given the indicated change in market credit spreads as of March 31, 2015:

Basis Point Change in Market Credit Spreads	Percentage change in market value of investments
+50	(1.9)%
+25	(1.0)%
-25	1.0%
-50	2.0%

Prepayment and Reinvestment Risk

Prepayment risk is the risk of an early, unscheduled return of principal on an investment. We are subject to prepayment risk from premiums paid on investments which we acquire. Purchase premiums on our investments are amortized as a reduction in interest income using the effective yield method under GAAP, adjusted for the actual and anticipated prepayment activity of the investment. An increase in the actual or expected rate of prepayment will typically accelerate the amortization of purchase premiums, thereby reducing the yield/interest income earned on such assets. Principal prepayments on our investments are influenced by changes in market interest rates and a variety of economic, geographic, government policy and other factors beyond our control.

Prepayment risk results from both our RMBS and CMBS investments. The majority of the loans underlying our RMBS are ARMs or hybrid ARMs. Prepayments on these loans accelerate in a declining interest rate environment, as the loans age, and as the loans near their respective interest rate reset dates, particularly the initial reset date. Our prepayment models anticipate acceleration of prepayments in these events. To the extent the actual prepayments exceed our modeled prepayments, or if we change our future prepayment expectations, we will record adjustments to our premium amortization which may negatively impact our net interest income and could impact the fair value of our RMBS.

As an indication of our prepayment risk on our RMBS portfolio, the following table summarizes information for our Agency RMBS portfolio regarding the net premium and weighted average coupon by months until interest rate reset ("MTR") or until maturity in the case of fixed-rate securities as of the end of the past four quarters:

42

Loans underlying our RMBS do not have any specific prepayment protection whereas loans underlying our CMBS and CMBS IO securities generally have some form of prepayment protection provisions (such as prepayment lock-outs) or prepayment compensation provisions (such as yield maintenance or prepayment penalties). Yield maintenance and prepayment penalty requirements are intended to create an economic disincentive for the loans to prepay; however, the amount of the prepayment penalty required to be paid may decline over time, and as loans age, interest rates decline, or market values of collateral supporting the loans increase, prepayment penalties may lessen as an economic disincentive to the borrower. Generally, our experience has been that prepayment lock-out and yield maintenance provisions result in stable prepayment performance from period to period. There are no prepayment protections, however, if the loan defaults and is partially or wholly repaid earlier as a result of loss mitigation actions taken by the underlying loan servicer. Historically, we have experienced low default rates on loans underlying CMBS and CMBS IO.

Because CMBS IO consist of rights to interest on the underlying commercial mortgage loan pools and do not have rights to principal payments on the underlying loans, prepayment risk on these securities would be particularly acute without these prepayment protection provisions. Prepayment protection and compensation provisions on Agency securities generally, but not always, differ by the issuer of the security, (i.e. Freddie Mac, Fannie Mae, or Ginnie Mae). The majority of our Agency CMBS IO are issued by Freddie Mac, and Agency CMBS IO issued by Freddie Mac generally have initial prepayment lock-outs followed by a defeasance period which on average extends to within six months of the stated maturities of the underlying loans. The following table details the fair value of our CMBS IO portfolio by issuer as of the end of the periods indicated:

($ in thousands)	March 31, 2015		December 31, 2014
Fannie Mae	$	27,889	$	28,765
Freddie Mac	396,304		408,698
Ginnie Mae	—		1,274
Non-Agency CMBS IO	339,996		325,119
	$	764,189	$	763,856

We seek to manage our prepayment risk on our MBS by diversifying our investments, seeking investments which we believe will have superior prepayment performance, and investing in securities which have some sort of prepayment prohibition or yield maintenance (as is the case with CMBS and CMBS IO). With respect to RMBS, we will seek to invest in RMBS where we believe the underlying loans have favorable prepayment characteristics such as lower loan balances or favorable origination, borrower or geographic characteristics.

We are also subject to reinvestment risk as a result of the prepayment, repayment and sales of our investments. Yields on assets in which we invest now are generally lower than yields on existing assets that we may sell or which may be repaid, due to lower overall interest rates and more competition for these as investment assets. As a result, our interest income may decline in the future, thereby reducing earnings per share. In order to maintain our investment portfolio size and our earnings, we need to reinvest our capital into new interest-earning assets. If we are unable to find suitable reinvestment opportunities, interest income on our investment portfolio and investment cash flows could be negatively impacted.

Credit Risk

Credit risk is the risk that we will not receive all contractual amounts due on investments that we own due to default by the borrower or due to a deficiency in proceeds from the liquidation of the collateral securing the obligation. We are also particularly exposed to credit risk on investments that we own at a premium. For investments owned at premiums, defaults on the underlying loan typically result in the complete loss of any remaining unamortized premium we paid.

We attempt to mitigate our credit risk by purchasing Agency MBS and higher quality non-Agency MBS. Agency MBS have credit risk to the extent that Fannie Mae or Freddie Mac fails to remit payments on the MBS for which they have issued a guaranty of payment. Given the improved financial performance and conservatorship of these entities and the continued support of the U.S. government, we believe this risk is low. For our non-Agency MBS, we will generally only purchase investment grade securities (rated 'BBB' or better by a least one of the nationally recognized statistical ratings organizations).

43

The majority of our non-Agency securities are CMBS and CMBS IO. The return we earn on these securities is dependent on the credit performance of the underlying commercial loans. In particular, since investments in CMBS IO pay interest from the underlying commercial mortgage loan pools, returns are more negatively impacted by liquidations of loans in the underlying loan pool. In order to manage our exposure to credit performance, we generally invest in securities with higher credit ratings and in securities where we have evaluated the credit profile of the underlying loan pool and can monitor its credit performance.

The following table presents information on our non-Agency MBS by credit rating as of March 31, 2015:

	March 31, 2015
($ in thousands)	CMBS		CMBS IO		RMBS		Total		Percentage
AAA	$	86,993	$	318,480	$	—	$	405,473	64.1	%
AA	60,383		18,640		—		79,023		12.5	%
A	31,108		—		—		31,108		4.9	%
Below A or not rated	37,781		2,876		76,642		117,299		18.5	%
	$	216,265	$	339,996	$	76,642	$	632,903	100.0	%

Liquidity Risk

We have liquidity risk principally from the use of recourse repurchase agreements to finance our ownership of securities. In general, our repurchase agreements provide a source of uncommitted short-term financing that finances a longer-term asset, thereby creating a mismatch between the maturity of the asset and of the associated financing. Our repurchase agreements are renewable at the discretion of our lenders and do not contain guaranteed roll-over terms. If we fail to repay the lender at maturity, the lender has the right to immediately sell the collateral and pursue us for any shortfall if the sales proceeds are inadequate to cover the repurchase agreement financing. In addition, repurchase agreements are collateral based and declines in the market value of our investments subject us to liquidity risk.

For further information, including how we attempt to mitigate liquidity risk and monitor our liquidity position, please refer to “Liquidity and Capital Resources” in Part 1, Item 2 of this Quarterly Report on Form 10-Q.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure controls and procedures.

Our management evaluated, with the participation of our Principal Executive Officer and Principal Financial Officer, the effectiveness of our disclosure controls and procedures, as defined in Exchange Act Rule 13a-15(e), as of the end of the period covered by this report. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2015 to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act 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 Principal Executive Officer and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting.

Our management is also responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f). There were no changes in our internal control over financial reporting during the three months ended March 31, 2015 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II.    OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company and its subsidiaries are parties to various legal proceedings. Although the ultimate outcome of these legal proceedings cannot be ascertained at this time, and the results of legal proceedings cannot be predicted with certainty, the Company believes, based on current knowledge, that the resolution of any of these proceedings will not have a material adverse effect on the Company’s consolidated financial condition or liquidity. However, the resolution of any of the proceedings could have a material impact on consolidated results of operations or cash flows in a given future reporting period as the proceedings are resolved.

There have been no material changes during the three months ended March 31, 2015 for the legal proceeding discussed in the Annual Report on Form 10-K for the year ended December 31, 2014.

ITEM 1A.    RISK FACTORS

Risks and uncertainties identified in our forward-looking statements contained in this Quarterly Report on Form 10-Q together with those previously disclosed in the Annual Report on Form 10-K for the year ended December 31, 2014 or those that are presently unforeseen could result in significant adverse effects on our financial condition, results of operations and cash flows.  See “Forward-Looking Statements” contained in Part 1, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” within this Quarterly Report on Form 10-Q as well as Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014.

ITEM 2.    UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

The Company has been authorized by its Board of Directors to repurchase up to $50 million of its outstanding shares of common stock through December 31, 2016. Subject to applicable securities laws and the terms of the Series A Preferred Stock designation and the Series B Preferred Stock designation, both of which are contained in our Articles of Incorporation, future repurchases of common stock will be made at times and in amounts as the Company deems appropriate, provided that the repurchase price per share is less than the Company's estimate of the current net book value of a share of common stock. Repurchases may be suspended or discontinued at any time.

The following table summarizes repurchases of our common stock that occurred during the three months ended March 31, 2015:

	Total Number of Shares Purchased (1)	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Number (or Approximate Dollar Value) of Shares that May Yet Be Purchased Under the Plans or Programs
					($ in thousands)
January 1, 2015 - January 31, 2015	5,261	$	8.39	—	$	50,000
February 1, 2015 - February 28, 2015	30,350	$	8.32	—	50,000
March 1, 2015 - March 31, 2015	46,442	$	8.21	16,140	49,868
Total	82,053	$	8.26	16,140	$	49,868

(1) A portion of these shares were withheld from certain employees to satisfy tax withholding obligations arising upon the vesting of restricted shares. Accordingly, these shares are not included in the calculation of approximate dollar value of shares that may yet be purchased under the $50 million repurchase plan authorized by the Company's Board of Directors.

As of March 31, 2015, shareholders' equity at risk did not exceed 10% for any of the Company's counterparties. The Company had $253,160 of its repurchase agreement balance as of March 31, 2015 outstanding under a term repurchase facility with Wells Fargo Bank National Association. This facility has an aggregate maximum borrowing capacity of $300,000 and is scheduled to mature on August 6, 2016, subject to early termination provisions contained in the master repurchase agreement. The facility is collateralized primarily by CMBS IO, and its weighted average borrowing rate as of March 31, 2015 was 1.02%.

As of March 31, 2015, the Company had repurchase agreement amounts outstanding with 20 of its 33 available counterparties. The Company's counterparties, as set forth in the master repurchase agreement with the counterparty, require the Company to comply with various customary operating and financial covenants, including, but not limited to, minimum net worth, maximum declines in net worth in a given period, and maximum leverage requirements as well as maintaining the Company's REIT status. In addition, some of the agreements contain cross default features, whereby default under an agreement with one lender simultaneously causes default under agreements with other lenders. To the extent that the Company fails to comply with the covenants contained in these financing agreements or is otherwise found to be in default under the terms of such agreements, the counterparty has the right to accelerate amounts due under the master repurchase agreement. The Company was in compliance with all covenants as of March 31, 2015.

Please see Note 5 for the Company's disclosures related to offsetting assets and liabilities.

(1) The current weighted average coupon ("WAC") is the gross interest rate of the pool of mortgages underlying the security weighted by the outstanding principal balance (or by notional balance in the case of an IO security).

(2) The notional balance for the Agency CMBS IO and non-Agency CMBS IO was $10,460,113 and $7,868,896, respectively, as of December 31, 2014.

The Company received proceeds of $102,923 and $59,799 for the sale of MBS during the three months ended March 31, 2015 and March 31, 2014, respectively. The following table presents the gross realized gains (losses) of those sales included in "gain (loss) on sale of investments, net" on the Company's consolidated statements of comprehensive income for the periods indicated:

	Three Months Ended
	March 31,
	2015			2014
($ in thousands)	Gain (Loss) Recognized			Gain (Loss) Recognized
Gross realized gains on sales of MBS	$	1,773		$	219
Gross realized losses on sales of MBS	(465		)	(3,526		)
Total gain (loss) on sale of investments, net	$	1,308		$	(3,307	)

The following table presents certain information for those Agency MBS in an unrealized loss position as of the dates indicated:

	March 31, 2015						December 31, 2014
	Fair Value		Gross Unrealized Losses			# of Securities	Fair Value		Gross Unrealized Losses			# of Securities
Continuous unrealized loss position for less than 12 months:
Agency MBS	$	261,035	$	(531	)	17	$	322,741	$	(879	)	24
Non-Agency MBS	79,310		(382		)	13	111,778		(625		)	24
Continuous unrealized loss position for 12 months or longer:
Agency MBS	$	1,030,027	$	(12,727	)	91	$	1,321,323	$	(21,491	)	113
Non-Agency MBS	1,224		(61		)	4	18,037		(159		)	5

Because the principal related to Agency MBS is guaranteed by the government-sponsored entities Fannie Mae and Freddie Mac which have the implicit guarantee of the U.S. government, the Company does not consider any of the unrealized losses on its Agency MBS to be credit related. Although the unrealized losses are not credit related, the Company assesses its ability and intent to hold any Agency MBS with an unrealized loss until the recovery in its value. This assessment is based on the amount of the unrealized loss and significance of the related investment as well as the Company’s current leverage and anticipated liquidity. Based on this analysis, the Company has determined that the unrealized losses on its Agency MBS as of March 31, 2015 and December 31, 2014 were temporary.

The Company also reviews any non-Agency MBS in an unrealized loss position to evaluate whether any decline in fair value represents an OTTI. The evaluation includes a review of the credit ratings of these non-Agency MBS and the seasoning of the mortgage loans collateralizing these securities as well as the estimated future cash flows which include projected losses. The Company performed this evaluation for the non-Agency MBS in an unrealized loss position and has determined that there have not been any adverse changes in the timing or amount of estimated future cash flows that necessitate a recognition of OTTI amounts as of March 31, 2015 or December 31, 2014.

Accounting Policies [Abstract]

Organization and Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

Dynex Capital, Inc., ("Company”) was incorporated in the Commonwealth of Virginia on December 18, 1987 and commenced operations in February 1988. The Company primarily earns income from investing on a leveraged basis in mortgage-backed securities ("MBS") that are issued or guaranteed by the U.S. Government or U.S. Government sponsored agencies ("Agency MBS") and MBS issued by others ("non-Agency MBS").

Basis of Presentation

The accompanying unaudited consolidated financial statements of Dynex Capital, Inc. and its subsidiaries (together, “Dynex” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10, Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all significant adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the consolidated financial statements have been included. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any other interim periods or for the entire year ending December 31, 2015. The unaudited consolidated financial statements included herein should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC.

Consolidation

The consolidated financial statements include the accounts of the Company and the accounts of its majority owned subsidiaries and variable interest entities ("VIE") for which it is the primary beneficiary. As a primary beneficiary, the Company has both the power to direct the activities that most significantly impact the economic performance of the VIE and a right to receive benefits or absorb losses of the entity that could be potentially significant to the VIE. The Company is required to reconsider its evaluation of whether to consolidate a VIE each reporting period, based upon changes in the facts and circumstances pertaining to the VIE. All intercompany accounts and transactions have been eliminated in consolidation.

The Company consolidates certain trusts through which it has securitized mortgage loans as a result of not meeting the sale criteria under GAAP at the time the financial assets were transferred to the trust. Additional information regarding the accounting policy for the Company's securitized mortgage loans is provided below under "Mortgage Loans Held for Investment, Net ".

Use of Estimates

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 the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenue and expenses during the reported period. Actual results could differ from those estimates. The most significant estimates used by management include, but are not limited to, fair value measurements of its investments, other-than-temporary impairments, contingencies, and amortization of premiums and discounts. These items are discussed further below within this note to the consolidated financial statements.

Income Taxes

The Company has elected to be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986 and the corresponding provisions of state law. To qualify as a REIT, the Company must meet certain tests including investing in primarily real estate-related assets and the required distribution of at least 90% of its annual REIT taxable income to stockholders after consideration of its net operating loss carryforward ("NOL") and not including taxable income retained in its taxable subsidiaries. As a REIT, the Company generally will not be subject to federal income tax on the amount of its income or gain that is distributed as dividends to shareholders.

The Company assesses its tax positions for all open tax years and determines whether the Company has any material unrecognized liabilities in accordance with Accounting Standards Codification "ASC" Topic 740. The Company records these liabilities, if any, to the extent they are deemed more likely than not to have been incurred.

Net Income (Loss) Per Common Share

The Company did not have any potentially dilutive securities outstanding during the three months ended March 31, 2015 or March 31, 2014.

Holders of unvested shares of the Company's issued and outstanding restricted common stock are eligible to receive non-forfeitable dividends. As such, these unvested shares are considered participating securities as per ASC Topic 260-10 and therefore are included in the computation of basic net income (loss) per share using the two-class method. Upon vesting, restrictions on transfer expire on each share of restricted stock, and each such share of restricted stock is converted to one equal share of common stock.

Because the Company's 8.50% Series A Cumulative Redeemable Preferred Stock (the “Series A Preferred Stock”) and 7.625% Series B Cumulative Redeemable Preferred Stock (the “Series B Preferred Stock”) are redeemable at the Company's option for cash only and may convert into shares of common stock only upon a change of control of the Company, the effect of those shares is excluded from the calculation of diluted net income (loss) per common share.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and highly liquid investments with original maturities of three months or less.

Restricted Cash

Restricted cash consists of cash the Company has pledged to cover initial and variation margin with its counterparties.

Mortgage-Backed Securities

In accordance with ASC Topic 320, the Company has designated its investments in MBS as available-for-sale ("AFS"). All of the Company’s MBS are recorded at fair value on the consolidated balance sheet. Changes in fair value for the Company's AFS securities are reported in other comprehensive income ("OCI") until each security is collected, disposed of, or determined to be other than temporarily impaired. Although the Company generally intends to hold its AFS securities until maturity, it may sell any of these securities as part of the overall management of its business. Upon the sale of an AFS security, any unrealized gain or loss is reclassified out of accumulated other comprehensive income ("AOCI") into net income as a realized "gain (loss) on sale of investments, net" using the specific identification method.

The Company’s MBS pledged as collateral against repurchase agreements and derivative instruments are included in MBS on the consolidated balance sheets with the fair value of the MBS pledged disclosed parenthetically.

Interest Income, Premium Amortization, and Discount Accretion.Interest income on MBS is accrued based on the outstanding principal balance (or notional balance in the case of interest-only, or "IO", securities) and their contractual terms.  Premiums and discounts on Agency MBS as well as any non-Agency MBS rated 'AA' and higher at the time of purchase are amortized into interest income over the expected life of such securities using the effective yield method and adjustments to premium amortization are made for actual cash payments as well as changes in projected future cash payments in accordance with ASC Topic 310-20. The Company's projections of future cash payments are based on input and analysis received from external sources and internal models, and includes assumptions about the amount and timing of credit losses, loan prepayment rates, fluctuations in interest rates, and other factors. On at least a quarterly basis, the Company reviews and makes any necessary adjustments to its cash flow projections and updates the yield recognized on these assets.

The Company holds non-Agency MBS that were rated less than 'AA' at the time of purchase by at least one national rating agency. These non-Agency MBS were purchased at discounts to their par value, which management does not believe to be substantial. The Company accretes the discount into income over the security's expected life, which reflects management's estimate of the security's projected cash flows in accordance with ASC Topic 325-40. Future changes in the timing of projected cash flows or differences arising between projected cash flows and actual cash flows received may result in a prospective change in the effective yield on those securities.

Determination of MBS Fair Value.The Company estimates the fair value of the majority of its MBS based upon prices obtained from third-party pricing services and broker quotes. The remainder of the Company's MBS are valued by discounting the estimated future cash flows derived from cash flow models that utilize information such as the security's coupon rate, estimated prepayment speeds, expected weighted average life, collateral composition, estimated future interest rates, expected losses, and credit enhancements as well as certain other relevant information. Refer to Note 6 for further discussion of MBS fair value measurements.

Other-than-Temporary Impairment.MBS is considered impaired when its fair value is less than its amortized cost. The Company evaluates all of its impaired MBS for other-than-temporary impairments ("OTTI") on at least a quarterly basis. An impairment is considered other-than-temporary if: (1) the Company intends to sell the MBS; (2) it is more likely than not that the Company will be required to sell the MBS before its fair value recovers; or (3) the Company does not expect to recover the full amortized cost basis of the MBS. If either of the first two conditions is met, the entire amount of the impairment is recognized in earnings. If the impairment is solely due to the inability to fully recover the amortized cost basis, the security is further analyzed to quantify any credit loss, which is the difference between the present value of cash flows expected to be collected on the MBS and its amortized cost. The credit loss, if any, is then recognized in earnings, while the balance of impairment related to other factors is recognized in other comprehensive income.

Following the recognition of an OTTI through earnings, a new cost basis is established for the security. Any subsequent recoveries in fair value may be accreted back into the amortized cost basis of the MBS on a prospective basis through interest income. Please see Note 2 for additional information related to the Company's evaluation for OTTI.

Mortgage Loans Held for Investment, Net

The Company originated or purchased mortgage loans from 1992 through 1998, and these mortgage loans are reported at amortized cost in accordance with ASC Topic 310-10. A portion of these loans is pledged as collateral to support the repayment of one remaining class of a securitization financing bond issued by the Company in 2002. The associated securitization financing bond is treated as debt of the Company and is presented as "non-recourse collateralized financing" on the consolidated balance sheet. Securitized mortgage loans can only be sold subject to the lien of the respective securitization financing indenture. An allowance has been established for currently existing and probable losses on the Company's mortgage loans held for investment.

Investment in Limited Partnership

The Company is a limited partner with a less than 50% interest in a limited partnership for which it does not have substantive participating or kick-out rights that overcome the general partner's presumption of control. The Company accounts for its investment in this limited partnership using the equity method of accounting, which requires initially recording an investment in the equity of an investee at cost and subsequently adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses, capital contributions and distributions, and other changes in equity.

Repurchase Agreements

Repurchase agreements are accounted for as secured borrowings under which the Company pledges its securities as collateral to secure a loan, which is equal in value to a specified percentage of the estimated fair value of the pledged collateral. The Company retains beneficial ownership of the pledged collateral. At the maturity of a repurchase agreement, the Company is required to repay the loan and concurrently receives back its pledged collateral from the lender or, with the consent of the lender, the Company may renew the agreement at the then prevailing financing rate. A repurchase agreement lender may require the Company to pledge additional collateral in the event of a decline in the fair value of the collateral pledged. Repurchase agreement financing is recourse to the Company and the assets pledged. Most of the Company’s repurchase agreements are based on the September 1996 version of the Bond Market Association Master Repurchase Agreement, which generally provides that the lender, as buyer, is responsible for obtaining collateral valuations from a generally recognized source agreed to by both the Company and the lender, or, in an instance when such source is not available, the value determination is made by the lender.

Derivative Instruments

The Company's derivative instruments, which currently include interest rate swaps and Eurodollar futures, are accounted for in accordance with ASC Topic 815, which requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet and to measure those instruments at fair value. All periodic interest costs and other changes in fair value, including gains and losses recognized upon termination, associated with derivative instruments are recorded in "gain (loss) on derivative instruments, net" on the Company's consolidated statement of comprehensive income. Please refer to Note 4 for additional information regarding the Company's accounting for its derivative instruments.

Although MBS have characteristics that meet the definition of a derivative instrument, ASC Topic 815 specifically excludes these instruments from its scope because they are accounted for as debt securities under ASC Topic 320.

Share-Based Compensation

Pursuant to the Company’s 2009 Stock and Incentive Plan ("SIP"), the Company may grant share-based compensation to eligible employees, directors or consultants or advisers to the Company, including stock awards, stock options, stock appreciation rights, dividend equivalent rights, performance shares, and restricted stock units. The Company's restricted stock currently issued and outstanding under this plan may be settled only in shares of its common stock, and therefore are treated as equity awards with their fair value measured at the grant date and recognized as compensation cost over the requisite service period with a corresponding credit to shareholders' equity. The requisite service period is the period during which an employee is required to provide service in exchange for an award, which is equivalent to the vesting period specified in the terms of the share-based based award. None of the Company's restricted stock awards have performance based conditions. The Company does not currently have any share-based compensation issued or outstanding other than restricted stock.

Contingencies

In the normal course of business, there are various lawsuits, claims, and other contingencies pending against the Company. On a quarterly basis, the Company evaluates whether to establish provisions for estimated losses from those matters in accordance with ASC Topic 450, which states that a liability is recognized for a contingent loss when: (a) the underlying causal event has occurred prior to the balance sheet date; (b) it is probable that a loss has been incurred; and (c) there is a reasonable basis for estimating that loss. A liability is not recognized for a contingent loss when it is only possible or remotely possible that a loss has been incurred, however, possible contingent losses shall be disclosed. If the contingent loss (or an additional loss in excess of any accrual) is at least a reasonable possibility and material, then the Company discloses a reasonable estimate of the possible loss or range of loss, if such reasonable estimate can be made. If the Company cannot make a reasonable estimate of the possible material loss, or range of loss, then that fact is disclosed. As of March 31, 2015, the Company does not have any contingencies for which it believes a probable loss has been incurred.

Recent Accounting Pronouncements

The Company does not believe there are any recently issued accounting pronouncements which will have a material effect on the Company's financial condition or results of operations upon their effective date.

Shareholders' Equity

SHAREHOLDERS' EQUITY

Preferred Stock

The Company has 2,300,000 shares of its 8.50% Series A Preferred Stock and 2,250,000 shares of its 7.625% Series B Preferred Stock issued and outstanding as of March 31, 2015 (collectively, the "Preferred Stock"). The Preferred Stock has no maturity and will remain outstanding indefinitely unless redeemed or otherwise repurchased or converted into common stock pursuant to the terms of the Preferred Stock. Except under certain limited circumstances intended to preserve the Company's REIT status, upon the occurrence of a change in control as defined in Article IIIA, Section 7(d) of the Company’s Articles of Incorporation, or to avoid the direct or indirect imposition of a penalty tax in respect of, or to protect the tax status of, any of the Company’s real estate mortgage investment conduits (“REMIC”) interests or a REMIC in which the Company may acquire an interest (as permitted by the Company’s Articles of Incorporation), the Company may not redeem the Series A Preferred Stock prior to July 31, 2017 or the Series B Preferred Stock prior to April 30, 2018. On or after these dates, at any time and from time to time, the Preferred Stock may be redeemed in whole, or in part, at the Company's option at a cash redemption price of $25.00 per share plus any accumulated and unpaid dividends. The Series A Preferred Stock pays a cumulative cash dividend equivalent to 8.50% of the $25.00 liquidation preference per share each year and the Series B Preferred Stock pays a cumulative cash dividend equivalent to 7.625% of the $25.00 liquidation preference per share each year. Because the Preferred Stock is redeemable only at the option of the issuer, it is classified as equity on the Company's consolidated balance sheet. The Company announced that it will pay its regular quarterly dividends on its Preferred Stock for the first quarter on April 15, 2015 to shareholders of record as of April 1, 2015.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

FAIR VALUE OF FINANCIAL INSTRUMENTS

ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 clarifies that fair value should be based on the assumptions market participants would use when pricing an asset or liability and also requires an entity to consider all aspects of nonperformance risk, including the entity's own credit standing, when measuring fair value of a liability. ASC Topic 820 established a valuation hierarchy of three levels as follows:

• Level 1 – Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities as of the measurement date.

• Level 2 – Inputs include quoted prices in active markets for similar assets or liabilities; quoted prices in inactive markets for identical or similar assets or liabilities; or inputs either directly observable or indirectly observable through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.  

• Level 3 – Unobservable inputs are supported by little or no market activity. The unobservable inputs represent management’s best estimate of how market participants would price the asset or liability at the measurement date.  Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.  

The following table presents the fair value of the Company’s assets and liabilities presented on its consolidated balance sheets, segregated by the hierarchy level of the fair value estimate, that are measured at fair value on a recurring basis as of the dates indicated:

	March 31, 2015

The Company did not have assets or liabilities measured at fair value on a non-recurring basis as of March 31, 2015 or December 31, 2014.

The Company's derivative assets and liabilities include interest rate swaps and Eurodollar futures. Interest rate swaps are valued using the income approach with the primary input being the forward interest rate swap curve, which is considered an observable input and thus their fair values are considered Level 2 measurements. Eurodollar futures are valued based on closing exchange prices on these contracts. Accordingly, these financial futures are classified as Level 1.

Agency MBS, as well a majority of non-Agency MBS, are substantially similar to securities that either are currently actively traded or have been recently traded in their respective market. Their fair values are derived from an average of multiple dealer quotes and thus are considered Level 2 fair value measurements. The Company’s remaining non-Agency MBS are comprised of securities for which there are not substantially similar securities that trade frequently, and their fair values are therefore considered Level 3 measurements. The Company determines the fair value of its Level 3 securities by discounting the estimated future cash flows derived from cash flow models using assumptions that are confirmed to the extent possible by third party dealers or other pricing indicators. Significant inputs into those pricing models are Level 3 in nature due to the lack of readily available market quotes. Information utilized in those pricing models include the security’s credit rating, coupon rate, estimated prepayment speeds, expected weighted average life, collateral composition, estimated future interest rates, expected credit losses, and credit enhancement as well as certain other relevant information. Significant changes in any of these inputs in isolation would result in a significantly different fair value measurement. Level 3 assets are generally most sensitive to the default rate and severity assumptions.

The table below presents information about the significant unobservable inputs used in the fair value measurement for the Company's Level 3 non-Agency CMBS and RMBS as of March 31, 2015:

	Quantitative Information about Level 3 Fair Value Measurements (1)
	Prepayment Speed	Default Rate		Severity		Discount Rate
Non-Agency CMBS	20 CPY	2.0	%	35.0	%	10.1	%

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2015

Accounting Policies [Abstract]

Organization [Text Block]

Organization

Dynex Capital, Inc., ("Company”) was incorporated in the Commonwealth of Virginia on December 18, 1987 and commenced operations in February 1988. The Company primarily earns income from investing on a leveraged basis in mortgage-backed securities ("MBS") that are issued or guaranteed by the U.S. Government or U.S. Government sponsored agencies ("Agency MBS") and MBS issued by others ("non-Agency MBS").

Basis of Presentation [Policy Text Block]

Basis of Presentation

The accompanying unaudited consolidated financial statements of Dynex Capital, Inc. and its subsidiaries (together, “Dynex” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10, Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all significant adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the consolidated financial statements have been included. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for any other interim periods or for the entire year ending December 31, 2015. The unaudited consolidated financial statements included herein should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 filed with the SEC.

Consolidation [Policy Text Block]

Consolidation

The consolidated financial statements include the accounts of the Company and the accounts of its majority owned subsidiaries and variable interest entities ("VIE") for which it is the primary beneficiary. As a primary beneficiary, the Company has both the power to direct the activities that most significantly impact the economic performance of the VIE and a right to receive benefits or absorb losses of the entity that could be potentially significant to the VIE. The Company is required to reconsider its evaluation of whether to consolidate a VIE each reporting period, based upon changes in the facts and circumstances pertaining to the VIE. All intercompany accounts and transactions have been eliminated in consolidation.

The Company consolidates certain trusts through which it has securitized mortgage loans as a result of not meeting the sale criteria under GAAP at the time the financial assets were transferred to the trust. Additional information regarding the accounting policy for the Company's securitized mortgage loans is provided below under "Mortgage Loans Held for Investment, Net ".

Use of Estimates [Policy Text Block]

Use of Estimates

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 the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenue and expenses during the reported period. Actual results could differ from those estimates. The most significant estimates used by management include, but are not limited to, fair value measurements of its investments, other-than-temporary impairments, contingencies, and amortization of premiums and discounts. These items are discussed further below within this note to the consolidated financial statements.

Federal Income Taxes [Policy Text Block]

Income Taxes

The Company has elected to be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986 and the corresponding provisions of state law. To qualify as a REIT, the Company must meet certain tests including investing in primarily real estate-related assets and the required distribution of at least 90% of its annual REIT taxable income to stockholders after consideration of its net operating loss carryforward ("NOL") and not including taxable income retained in its taxable subsidiaries. As a REIT, the Company generally will not be subject to federal income tax on the amount of its income or gain that is distributed as dividends to shareholders.

The Company assesses its tax positions for all open tax years and determines whether the Company has any material unrecognized liabilities in accordance with Accounting Standards Codification "ASC" Topic 740. The Company records these liabilities, if any, to the extent they are deemed more likely than not to have been incurred.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and highly liquid investments with original maturities of three months or less.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

Restricted Cash

Restricted cash consists of cash the Company has pledged to cover initial and variation margin with its counterparties.

Mortgage Backed Securities [Policy Text Block]

Mortgage-Backed Securities

In accordance with ASC Topic 320, the Company has designated its investments in MBS as available-for-sale ("AFS"). All of the Company’s MBS are recorded at fair value on the consolidated balance sheet. Changes in fair value for the Company's AFS securities are reported in other comprehensive income ("OCI") until each security is collected, disposed of, or determined to be other than temporarily impaired. Although the Company generally intends to hold its AFS securities until maturity, it may sell any of these securities as part of the overall management of its business. Upon the sale of an AFS security, any unrealized gain or loss is reclassified out of accumulated other comprehensive income ("AOCI") into net income as a realized "gain (loss) on sale of investments, net" using the specific identification method.

The Company’s MBS pledged as collateral against repurchase agreements and derivative instruments are included in MBS on the consolidated balance sheets with the fair value of the MBS pledged disclosed parenthetically.

Interest Income, Premium Amortization, and Discount Accretion.Interest income on MBS is accrued based on the outstanding principal balance (or notional balance in the case of interest-only, or "IO", securities) and their contractual terms.  Premiums and discounts on Agency MBS as well as any non-Agency MBS rated 'AA' and higher at the time of purchase are amortized into interest income over the expected life of such securities using the effective yield method and adjustments to premium amortization are made for actual cash payments as well as changes in projected future cash payments in accordance with ASC Topic 310-20. The Company's projections of future cash payments are based on input and analysis received from external sources and internal models, and includes assumptions about the amount and timing of credit losses, loan prepayment rates, fluctuations in interest rates, and other factors. On at least a quarterly basis, the Company reviews and makes any necessary adjustments to its cash flow projections and updates the yield recognized on these assets.

The Company holds non-Agency MBS that were rated less than 'AA' at the time of purchase by at least one national rating agency. These non-Agency MBS were purchased at discounts to their par value, which management does not believe to be substantial. The Company accretes the discount into income over the security's expected life, which reflects management's estimate of the security's projected cash flows in accordance with ASC Topic 325-40. Future changes in the timing of projected cash flows or differences arising between projected cash flows and actual cash flows received may result in a prospective change in the effective yield on those securities.

Determination of MBS Fair Value.The Company estimates the fair value of the majority of its MBS based upon prices obtained from third-party pricing services and broker quotes. The remainder of the Company's MBS are valued by discounting the estimated future cash flows derived from cash flow models that utilize information such as the security's coupon rate, estimated prepayment speeds, expected weighted average life, collateral composition, estimated future interest rates, expected losses, and credit enhancements as well as certain other relevant information. Refer to Note 6 for further discussion of MBS fair value measurements.

Other-than-Temporary Impairment.MBS is considered impaired when its fair value is less than its amortized cost. The Company evaluates all of its impaired MBS for other-than-temporary impairments ("OTTI") on at least a quarterly basis. An impairment is considered other-than-temporary if: (1) the Company intends to sell the MBS; (2) it is more likely than not that the Company will be required to sell the MBS before its fair value recovers; or (3) the Company does not expect to recover the full amortized cost basis of the MBS. If either of the first two conditions is met, the entire amount of the impairment is recognized in earnings. If the impairment is solely due to the inability to fully recover the amortized cost basis, the security is further analyzed to quantify any credit loss, which is the difference between the present value of cash flows expected to be collected on the MBS and its amortized cost. The credit loss, if any, is then recognized in earnings, while the balance of impairment related to other factors is recognized in other comprehensive income.

Following the recognition of an OTTI through earnings, a new cost basis is established for the security. Any subsequent recoveries in fair value may be accreted back into the amortized cost basis of the MBS on a prospective basis through interest income. Please see Note 2 for additional information related to the Company's evaluation for OTTI.

Mortgage Loans Held for Investment, Net [Policy Text Block]

Mortgage Loans Held for Investment, Net

The Company originated or purchased mortgage loans from 1992 through 1998, and these mortgage loans are reported at amortized cost in accordance with ASC Topic 310-10. A portion of these loans is pledged as collateral to support the repayment of one remaining class of a securitization financing bond issued by the Company in 2002. The associated securitization financing bond is treated as debt of the Company and is presented as "non-recourse collateralized financing" on the consolidated balance sheet. Securitized mortgage loans can only be sold subject to the lien of the respective securitization financing indenture. An allowance has been established for currently existing and probable losses on the Company's mortgage loans held for investment.

Investment in Limited Partnership [Policy Text Block]

Investment in Limited Partnership

The Company is a limited partner with a less than 50% interest in a limited partnership for which it does not have substantive participating or kick-out rights that overcome the general partner's presumption of control. The Company accounts for its investment in this limited partnership using the equity method of accounting, which requires initially recording an investment in the equity of an investee at cost and subsequently adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses, capital contributions and distributions, and other changes in equity.

Repurchase Agreements [Policy Text Block]

Repurchase Agreements

Repurchase agreements are accounted for as secured borrowings under which the Company pledges its securities as collateral to secure a loan, which is equal in value to a specified percentage of the estimated fair value of the pledged collateral. The Company retains beneficial ownership of the pledged collateral. At the maturity of a repurchase agreement, the Company is required to repay the loan and concurrently receives back its pledged collateral from the lender or, with the consent of the lender, the Company may renew the agreement at the then prevailing financing rate. A repurchase agreement lender may require the Company to pledge additional collateral in the event of a decline in the fair value of the collateral pledged. Repurchase agreement financing is recourse to the Company and the assets pledged. Most of the Company’s repurchase agreements are based on the September 1996 version of the Bond Market Association Master Repurchase Agreement, which generally provides that the lender, as buyer, is responsible for obtaining collateral valuations from a generally recognized source agreed to by both the Company and the lender, or, in an instance when such source is not available, the value determination is made by the lender.

Derivative Instruments [Policy Text Block]

Derivative Instruments

The Company's derivative instruments, which currently include interest rate swaps and Eurodollar futures, are accounted for in accordance with ASC Topic 815, which requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet and to measure those instruments at fair value. All periodic interest costs and other changes in fair value, including gains and losses recognized upon termination, associated with derivative instruments are recorded in "gain (loss) on derivative instruments, net" on the Company's consolidated statement of comprehensive income. Please refer to Note 4 for additional information regarding the Company's accounting for its derivative instruments.

Although MBS have characteristics that meet the definition of a derivative instrument, ASC Topic 815 specifically excludes these instruments from its scope because they are accounted for as debt securities under ASC Topic 320.

Stock-based Compensation [Policy Text Block]

Share-Based Compensation

Pursuant to the Company’s 2009 Stock and Incentive Plan ("SIP"), the Company may grant share-based compensation to eligible employees, directors or consultants or advisers to the Company, including stock awards, stock options, stock appreciation rights, dividend equivalent rights, performance shares, and restricted stock units. The Company's restricted stock currently issued and outstanding under this plan may be settled only in shares of its common stock, and therefore are treated as equity awards with their fair value measured at the grant date and recognized as compensation cost over the requisite service period with a corresponding credit to shareholders' equity. The requisite service period is the period during which an employee is required to provide service in exchange for an award, which is equivalent to the vesting period specified in the terms of the share-based based award. None of the Company's restricted stock awards have performance based conditions. The Company does not currently have any share-based compensation issued or outstanding other than restricted stock.

Contingencies [Policy Text Block]

Contingencies

In the normal course of business, there are various lawsuits, claims, and other contingencies pending against the Company. On a quarterly basis, the Company evaluates whether to establish provisions for estimated losses from those matters in accordance with ASC Topic 450, which states that a liability is recognized for a contingent loss when: (a) the underlying causal event has occurred prior to the balance sheet date; (b) it is probable that a loss has been incurred; and (c) there is a reasonable basis for estimating that loss. A liability is not recognized for a contingent loss when it is only possible or remotely possible that a loss has been incurred, however, possible contingent losses shall be disclosed. If the contingent loss (or an additional loss in excess of any accrual) is at least a reasonable possibility and material, then the Company discloses a reasonable estimate of the possible loss or range of loss, if such reasonable estimate can be made. If the Company cannot make a reasonable estimate of the possible material loss, or range of loss, then that fact is disclosed. As of March 31, 2015, the Company does not have any contingencies for which it believes a probable loss has been incurred.

Recent Accounting Pronouncements [Text Block]

Recent Accounting Pronouncements

The Company does not believe there are any recently issued accounting pronouncements which will have a material effect on the Company's financial condition or results of operations upon their effective date.

Equity [Abstract]

Preferred Stock [Text Block]

The Company has 2,300,000 shares of its 8.50% Series A Preferred Stock and 2,250,000 shares of its 7.625% Series B Preferred Stock issued and outstanding as of March 31, 2015 (collectively, the "Preferred Stock"). The Preferred Stock has no maturity and will remain outstanding indefinitely unless redeemed or otherwise repurchased or converted into common stock pursuant to the terms of the Preferred Stock. Except under certain limited circumstances intended to preserve the Company's REIT status, upon the occurrence of a change in control as defined in Article IIIA, Section 7(d) of the Company’s Articles of Incorporation, or to avoid the direct or indirect imposition of a penalty tax in respect of, or to protect the tax status of, any of the Company’s real estate mortgage investment conduits (“REMIC”) interests or a REMIC in which the Company may acquire an interest (as permitted by the Company’s Articles of Incorporation), the Company may not redeem the Series A Preferred Stock prior to July 31, 2017 or the Series B Preferred Stock prior to April 30, 2018. On or after these dates, at any time and from time to time, the Preferred Stock may be redeemed in whole, or in part, at the Company's option at a cash redemption price of $25.00 per share plus any accumulated and unpaid dividends. The Series A Preferred Stock pays a cumulative cash dividend equivalent to 8.50% of the $25.00 liquidation preference per share each year and the Series B Preferred Stock pays a cumulative cash dividend equivalent to 7.625% of the $25.00 liquidation preference per share each year. Because the Preferred Stock is redeemable only at the option of the issuer, it is classified as equity on the Company's consolidated balance sheet.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

DERIVATIVES

     The Company utilizes derivative instruments to economically hedge a portion of its exposure to market risks, primarily interest rate risk. The Company primarily uses pay-fixed interest rate swaps and Eurodollar contracts to hedge its exposure to changes in interest rates and uses receive-fixed interest rate swaps to offset a portion of its pay-fixed interest rate swaps in order to manage its overall hedge position. The objective of the Company's risk management strategy is to mitigate declines in book value resulting from fluctuations in the fair value of the Company's assets from changing interest rates and to protect the Company's earnings from rising interest rates. Please refer to Note 1 for information related to the Company's accounting policy for its derivative instruments.

The table below summarizes information about the Company’s derivative instruments treated as trading instruments on its consolidated balance sheet as of the dates indicated:

(1) The Eurodollar futures aggregate notional amount represents the total notional of the 3-month contracts with expiration dates from 2015 to 2020. The maximum notional outstanding for any future 3-month period did not exceed $1,300,000 as of March 31, 2015 or as of December 31, 2014.

The following table summarizes the contractual maturities remaining for the Company’s outstanding interest rate swap agreements as of March 31, 2015:

The table above contains forward-starting interest rate swaps with a combined notional value of $425,000 and a weighted average pay-fixed rate of 1.98% which will not be effective until 2016.

The following table summarizes the volume of activity related to derivative instruments for the period indicated:

For the three months ended March 31, 2015:	Beginning of Period Notional Amount		Additions		Settlement, Termination, Expiration or Exercise			End of Period Notional Amount

The table below provides detail of the Company's "loss on derivative instruments, net" by type of interest rate derivative for the periods indicated:

	Three Months Ended
	March 31,
Type of Derivative Instrument	2015			2014
Receive-fixed interest rate swaps	$	4,528		$	—
Pay-fixed interest rate swaps	(13,363		)	(9,008		)
Eurodollar futures	(16,488		)	(4,414		)
Loss on derivative instruments, net	$	(25,323	)	$	(13,422	)

Effective June 30, 2013, the Company de-designated certain interest rate swap agreements as cash flow hedges under ASC Topic 815. There is a net unrealized loss of $1,520 remaining in AOCI on the Company's consolidated balance sheet as of March 31, 2015 which represents the activity related to these interest rate swap agreements while they were previously designated as cash flow hedges, and this amount will be recognized in the Company's net income as a portion of "interest expense" over the remaining contractual life of the agreements. The Company estimates the portion of existing net unrealized loss on discontinued cash flow hedges expected to be reclassified to net income within the next 12 months is $2,429.

Many of the Company's interest rate swaps were entered into under bilateral agreements which contain various covenants related to the Company’s credit risk. Specifically, if the Company defaults on any of its indebtedness, including those circumstances whereby repayment of the indebtedness has not yet been accelerated by the lender, or is declared in default of any of its covenants with any counterparty, then the Company could also be declared in default under the bilateral agreement. Additionally, these agreements allow those counterparties to require settlement of its outstanding derivative transactions if the Company fails to earn net income excluding derivative gains and losses greater than one dollar as measured on a rolling two quarter basis. These interest rate agreements also contain provisions whereby, if the Company fails to maintain a minimum net amount of shareholders’ equity, then the Company may be declared in default on its derivative obligations. The Company was in compliance with all covenants under bilateral agreements on March 31, 2015.

Please see Note 5 for the Company's disclosures related to offsetting assets and liabilities.
