PART I.

ITEM 1. BUSINESS

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 as discussed further below.

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 as discussed further below. 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.

Interest rates on loans collateralizing Agency and non-Agency ARMs are based on specific index rates, such as the London Interbank Offered Rate, or LIBOR, the one-year constant maturity treasury rate, or CMT, the Federal Reserve U.S. 12-month

1

cumulative average one-year CMT, or MTA, or the 11th District Cost of Funds Index, or COFI. These loans will typically have interim and lifetime caps on interest rate adjustments, or interest rate caps, limiting the amount that the rates on these loans may reset in any given period.

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 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.

Operating Policies and Restrictions

Our Operating Policies set forth investment and risk limitations as they relate to the Company's investment activities and are reviewed annually by the Board but may be updated or amended at anytime by the Board. We also manage our operations and investments to comply with various REIT limitations (as discussed further below in “Federal Income Tax Considerations”) and to avoid qualifying as an investment company as such term is defined in the Investment Company Act of 1940 ("the 1940 Act") or as a commodity pool operator under the Commodity Exchange Act.

The Operating Policies in effect as of December 31, 2014 target an allocation of 40% of our assets to non-Agency MBS and limit our purchases of non-investment grade and non-rated MBS to no more than 10% of our total capital. Investment grade MBS are MBS which are rated 'BBB' or higher by at least one nationally recognized statistical ratings organization. We will conduct our own independent evaluation of the credit risk on any non-Agency MBS, such that we do not rely solely on the security’s credit rating. In general, our limited purchases of non-rated MBS in recent years have been shorter duration securities which we believe to have minimal credit risk as opposed to longer duration MBS that may have more significant credit risk.

The Operating Policies also limit the overall leverage of the Company to seven times our shareholders’ equity capital and place limits on certain risks to which we are exposed, such as interest rate and convexity risk, our earnings at risk, and our shareholders’ equity at risk as a result of changes in interest rates, prepayment rates, investment prices and spreads, and others items. The Operating Policies require us to perform a variety of stress tests to model the effect on the investment portfolio value and our liquidity of adverse market conditions.

Investment Philosophy and Strategy

Our investment philosophy encompasses a macroeconomic, top-down approach that focuses on the expected risk-adjusted outcome of any investment. Key points of our investment philosophy include the following:

• understanding macroeconomic conditions including the current state of the U.S. and global economies;

• understanding the regulatory environment, competition for assets, and the terms and availability of financing;

• sector analysis including understanding absolute returns, relative returns and risk-adjusted returns;

• security and financing analysis including sensitivity analysis on credit, interest rate volatility, and market value risk; and

• managing performance and portfolio risks, including interest rate, credit, prepayment, and liquidity risks.

Our investment philosophy will dictate our investment strategy. In executing our strategy, we seek to balance the risks of owning various types of mortgage assets with the earnings opportunity on the investments. We believe our investment strategy provides superior diversification of these risks across our investment portfolio and therefore provides ample opportunities to generate attractive risk-adjusted returns while protecting our shareholders’ capital.

2

The performance of our investment portfolio will depend on many factors including but not limited to interest rates, trends of interest rates, the steepness of interest rate curves, prepayment rates on our investments, demand for our investments, general market liquidity, and economic conditions and their impact on the credit performance of our investments. In addition, our business model may be impacted by other factors such as the state of the overall credit markets, which could impact the availability and costs of financing. See “Factors that Affect Our Results of Operations and Financial Condition” below and "Risk Factors-Risks Related to Our Business" in Item 1A of Part I of this Annual Report on Form 10-K for further discussion.

Financing and Hedging

We finance our investments primarily through the use of recourse repurchase agreements, and to a lesser extent, non-recourse collateralized financing.

Repurchase Agreements. The majority of our repurchase agreement financing is uncommitted short-term financing in which we pledge our MBS as collateral to secure loans made by the repurchase agreement counterparty. These repurchase agreements generally have original terms to maturity of 30 days to one year, though in some instances we may enter into longer- dated maturities depending on market conditions, and carry a rate of interest which is usually based on a spread to LIBOR and fixed for the term of the borrowing. Borrowings under these repurchase agreements are renewable at the discretion of our lenders and do not contain guaranteed roll-over terms. We also have available to us a committed repurchase agreement financing facility which was amended on February 5, 2015 to increase the aggregate borrowing capacity to $300.0 million and to extend its expiration date to August 6, 2016. The amount borrowed under a repurchase agreement is limited by the lender to a percentage of the estimated market value of the pledged collateral (or "haircut"), which is generally up to 95% of the estimated market value for Agency MBS, up to 90% for higher credit quality non-Agency MBS, and up to 85% for CMBS IO and for non-rated or lower credit quality non-Agency MBS. The difference between the market value of the pledged MBS collateral and the amount of the repurchase agreement is the amount of equity we have in the position and is intended to provide the lender some protection against fluctuations of value in the collateral and/or the failure by us to repay the borrowing at maturity.

The fair value of MBS fluctuates primarily as a result of principal payments and changes in market interest rates and spreads, prevailing market yields, actual or anticipated prepayment speeds, and other market conditions. If the fair value of the MBS pledged as collateral declines below the lender's required haircut, the lender has the right to initiate a margin call which requires us to pledge additional assets to collateralize the outstanding repurchase agreement borrowings. Lenders may also initiate margin calls during periods of market stress as a result of actual or expected volatility in asset prices.If we fail to meet any margin call, our lenders also have the right to terminate the repurchase agreement and sell any collateral pledged. Therefore, we attempt to maintain cash and other liquid securities in sufficient amounts to manage our exposure to margin calls by lenders.

Repurchase agreement financing is provided principally by major financial institutions and broker-dealers. A significant source of liquidity for the repurchase agreement market is money market funds which provide collateral-based lending to the financial institutions and broker-dealer community that, in turn, is provided to the repurchase agreement market. In order to reduce our exposure to counterparty-related risk, we generally seek to diversify our exposure by entering into repurchase agreements with multiple lenders.

For further discussion of repurchase agreement financing including significant risks, please refer to "Risk Factors-Risks Related to Our Business" in Item 1A of Part 1 and "Liquidity and Capital Resources" in Item 7 of Part II of this Annual Report on Form 10-K.

Derivative Instruments. We use a variety of derivative instruments to mitigate our exposure to market events outside of our control which could impact our earnings, cash flow or book value. Our hedging activities attempt primarily to reduce our exposure to adverse effects of changes in interest rates. For example, given the nature of our investing and financing activities, in a period of rising interest rates our earnings and cash flow may be negatively impacted by borrowing costs increasing faster than income from our assets, and our book value may decline as a result of declining market values of our MBS. We enter into derivative instruments in an attempt to partially or fully mitigate our exposure to these changes in interest rates. We typically utilize interest rate swap agreements and Eurodollar futures to hedge interest rate risk, but may also utilize interest rate cap or floor agreements, put and call options on securities or securities underlying futures contracts, forward rate agreements, or swaptions.

3

As of December 31, 2014, our derivative instruments consisted of interest rate swap agreements and Eurodollar contracts. In conducting our hedging activities, we intend to comply with REIT and tax limitations on our hedging instruments which could limit our activities and the instruments that we may use. We also intend to enter into derivative contracts only with the counterparties that we believe have a strong credit rating to help mitigate the risk of counterparty default or insolvency.

Non-Recourse Collateralized Financing. In the past we have utilized securitization financing to finance securitized mortgage loans and certain MBS. Securitization financing is term financing collateralized by securitized mortgage loans and is non-recourse to us. Payments received on securitized mortgage loans and reinvestment income earned thereon is used to make payments on the securitization financing bonds. Management does not currently have plans to enter into any additional securitization financing arrangements.

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. Please refer to Part I, Item 1A, "Risk Factors" as well as Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Item 7A, "Quantitative and Qualitative Disclosures about Market Risk" of this Annual Report on Form 10-K for a detailed discussion of these factors and others that have the potential to impact our results of operations and financial condition.

INDUSTRY OVERVIEW

The public mortgage REIT industry includes approximately 37 companies with a total market capitalization of approximately $62.0 billion as of December 31, 2014. Mortgage REITs provide liquidity to the U.S. real estate markets through the purchase of RMBS and CMBS and through the origination or purchase of mortgage loans. The business models of mortgage REITs range from investing only in Agency MBS to investing substantially in non-investment grade MBS and originating and securitizing loans. Each mortgage REIT will assume risks in its investment strategy. Whereas we invest in shorter-duration and higher quality MBS in order to mitigate interest rate risk and credit risk, other mortgage REITs may be willing to accept more of these risks than we are and invest in mortgage assets that we do not.

Given the need for private capital to replace the capital currently supporting mortgage finance (from governmental and quasi-governmental public entities such as Fannie Mae, Freddie Mac, Ginnie Mae and the Federal Reserve), we believe that mortgage REITs will continue to increase in importance to the U.S. housing and mortgage finance industries. In addition, the uncertainty around regulation of financial institutions under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") , minimum capital standards implemented under the Basel III Accord, increased risk-weightings for certain types of mortgage loans held by depository institutions, increased regulatory requirements related to origination of certain types of residential mortgage loans, and other potential regulatory changes, may further impact capital formation in the U.S. mortgage market which could favor mortgage REITs. There are potential consequences to increased regulation however, including increasing borrowing costs or reduced availability of repurchase agreement financing and the need to post more capital to leverage our investments and/or enter into derivative instruments.

COMPETITION

The financial services industry in which we compete is a highly competitive market. In purchasing investments and obtaining financing, we compete with other mortgage REITs, broker dealers and investment banking firms, mutual funds, banks, hedge funds, mortgage bankers, insurance companies, governmental bodies, and other entities, many of which have greater financial resources and a lower cost of capital than we do. Increased competition in the market may reduce the available supply of investments

4

and may drive prices of investments to unacceptable levels which would negatively impact our ability to earn an acceptable amount of income from these investments. Competition can also reduce the availability of borrowing capacity at our repurchase agreement counterparties as such capacity is not unlimited, and many of our repurchase agreement counterparties limit the amount of financing they offer to the mortgage REIT industry.

FEDERAL INCOME TAX CONSIDERATIONS

As a REIT, we are required to abide by certain requirements for qualification as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To retain our REIT status, the REIT rules generally require that we invest primarily in real estate-related assets, that our activities be passive rather than active and that we distribute annually to our shareholders substantially all of our taxable income, after certain deductions, including deductions for our tax net operating loss (“NOL”) carryforward. We could be subject to income tax if we failed to satisfy those requirements. We use the calendar year for both tax and financial reporting purposes.

We utilize our NOL carryforward to offset our taxable earnings after taking the REIT distribution requirements into account. As a result of our public offering of common stock in February 2012, we incurred an "ownership change" as such term is defined in Section 382 of the Code. Because of this ownership change, the amount of the NOL carryforward that we may use each year is limited to approximately $13.5 million, and portions of this amount not utilized are accumulated and rolled forward to the following year. Our NOL carryforward begins to expire substantially in 2020. The following table provides a rollforward of our NOL carryforward for the periods indicated:

	Cumulative NOL Available for Use		NOL Balance Remaining
As of December 31, 2012:			$	145,759
Amount released for the year ended December 31, 2012 (1)	$	11,249
Amount released for the year ended December 31, 2013	13,451
Amount released for the year ended December 31, 2014	13,451
Amount available for use as of December 31, 2014	38,151
Less amount used for the year ended December 31, 2012			—
Less amount used for the year ended December 31, 2013			—
Estimated amount to be used for the year ended December 31, 2014 (2)			(25,743		)
Estimate of NOL remaining as of December 31, 2014 (2)			$	120,016

(1) Prorated to account for timing of Section 382 ownership change during the year.

(2) Subject to completion of our 2014 federal income tax return.

There may be differences between taxable income and income computed in accordance with U.S. generally accepted accounting principles (“GAAP”). These differences primarily arise from timing differences in the recognition of revenue and expense for tax and GAAP purposes.

Failure to satisfy certain Code requirements could cause us to lose our status as a REIT. If we failed to qualify as a REIT for any taxable year, we may be subject to federal income tax (including any applicable alternative minimum tax) at regular corporate rates and would not receive deductions for dividends paid to shareholders. We could, however, utilize our NOL carryforward to offset all or part of our taxable income to the extent the NOL is available to us based on the limitations described above. If we lost or otherwise surrendered our status as a REIT, we could not elect REIT status again for five years. Several of our investments in securitized mortgage loans have ownership restrictions limiting their ownership to REITs. Therefore, if we fail to maintain our REIT status, we would have to sell these investments or otherwise provide for REIT ownership of these investments. In addition, many of our repurchase agreement lenders and interest rate swap counterparties require us to maintain our REIT status. If we were to lose our REIT status, these lenders would have the right to terminate any repurchase agreement borrowings and interest rate swaps outstanding at that time.

5

Qualification as a REIT

Qualification as a REIT requires that we satisfy a variety of tests relating to our income, assets, distributions and ownership. The significant tests are summarized below.

Sources of Income. To continue qualifying as a REIT, we must satisfy two distinct tests with respect to the sources of our income: the “75% income test” and the “95% income test.” The 75% income test requires that we derive at least 75% of our gross income (excluding gross income from prohibited transactions) from certain real estate-related sources. In order to satisfy the 95% income test, 95% of our gross income for the taxable year must consist of either income that qualifies under the 75% income test or certain other types of passive income.

If we fail to meet either the 75% income test or the 95% income test, or both, in a taxable year, we might nonetheless continue to qualify as a REIT, if our failure was due to reasonable cause and not willful neglect and the nature and amounts of our items of gross income were properly disclosed to the Internal Revenue Service. However, in such a case we would be required to pay a tax equal to 100% of any excess non-qualifying income.

Nature and Diversification of Assets. At the end of each calendar quarter, we must meet multiple asset tests. Under the “75% asset test”, at least 75% of the value of our total assets must represent cash or cash items (including receivables), government securities or real estate assets. Under the “10% asset test,” we may not own more than 10% of the outstanding voting power or value of securities of any single non-governmental issuer, provided such securities do not qualify under the 75% asset test or relate to taxable REIT subsidiaries. Under the “5% asset test,” ownership of any stocks or securities that do not qualify under the 75% asset test must be limited, in respect of any single non-governmental issuer, to an amount not greater than 5% of the value of our total assets (excluding ownership of any taxable REIT subsidiaries).

If we inadvertently fail to satisfy one or more of the asset tests at the end of a calendar quarter, such failure would not cause us to lose our REIT status, provided that (i) we satisfied all of the asset tests at the close of the preceding calendar quarter and (ii) the discrepancy between the values of our assets and the standards imposed by the asset tests either did not exist immediately after the acquisition of any particular asset or was not wholly or partially caused by such an acquisition. If the condition described in clause (ii) of the preceding sentence was not satisfied, we still could avoid disqualification by eliminating any discrepancy within 30 days after the close of the calendar quarter in which it arose.

Ownership. In order to maintain our REIT status, we must not be deemed to be closely held and must have more than 100 shareholders. The closely held prohibition requires that not more than 50% of the value of our outstanding shares be owned by five or fewer persons at any time during the last half of our taxable year. The "more than 100 shareholders" rule requires that we have at least 100 shareholders for 335 days of a twelve-month taxable year. In the event that we failed to satisfy the ownership requirements we would be subject to fines and be required to take curative action to meet the ownership requirements in order to maintain our REIT status.

EMPLOYEES

As of December 31, 2014, we have 17 employees and one corporate office in Glen Allen, Virginia. None of our employees are covered by any collective bargaining agreements, and we are not aware of any union organizing activity relating to our employees.

The following is a summary of the risk factors that we believe are most relevant to our business. These are factors which, individually or in the aggregate, we think could cause our actual results to differ significantly from anticipated or historical results. In addition to understanding the key risks described below, investors should understand that it is not possible to predict or identify all risk factors, and consequently, the following is not a complete discussion of all potential risks or uncertainties.

RISKS RELATED TO OUR BUSINESS

Our strategy of using leverage to enhance returns to our shareholders increases the risk that we may incur losses, declines in book value, and material decreases in our liquidity.

The use of leverage in our business increases the risk of volatility in returns to our shareholders and increases the risk of a material decline in our book value and liquidity. Leverage increases returns on our invested capital if we can earn a greater return on investments purchased with leveraged funds than our cost of leverage, but can decrease returns on our invested capital if the cost of such leverage increases without having adequately hedged against such increase or if our ability to access or maintain leverage is limited or restricted in a material way. The use of leverage will also magnify increases or decreases in our book value depending on the change in value of assets that we purchase (which are generally longer-term in nature) relative to the change in value of the financing (which are generally shorter-term in nature) and the change in fair value of our hedges. The increase in liquidity risk stems from the potential for margin calls by our lenders for fluctuations in collateral values or if the lender fails to renew or roll over the financing.

Our ability to access cost-effective leverage sufficient to generate acceptable returns to our shareholders is impacted by the following:

• market conditions and overall market volatility and liquidity;

• regulation of our lenders;

• the liquidity of our investments;

• the market value of our investments;

• the ‘haircut’ our lenders accept for the types of investments we use as collateral, and;

• the willingness of our lenders to finance the types of investments we choose.

Because repurchase agreements are short-term commitments of capital, changes in conditions in the repurchase markets may make it more difficult for us to secure continued financing. In periods of high volatility such as was experienced during the financial crisis in 2008, some lenders may lose their ability or curtail their willingness to provide financing. Additionally, regulatory capital requirements adopted by financial and banking regulators and imposed on our lenders have changed significantly since 2008 and as a result the cost of the financing has increased, and may continue to increase from the higher regulatory costs and regulatory capital requirements. Our lenders also may revise their eligibility requirements for the types of assets they are willing to finance or the terms of such financings, based on, among other factors, the regulatory environment and their management of perceived risk related to such financings. Moreover, the amount of financing we receive under our repurchase agreements will be directly related to the lenders' valuation of the assets that secure the outstanding borrowings. All of these circumstances could increase the cost of our borrowings or reduce our ability to access leverage, which could adversely affect our financial condition and results of operations, and could also force us to sell assets at significant losses if the unfavorable market environment requires us to deleverage.

We may be required to post large amounts of additional assets as collateral or margin to secure our leveraged positions in the event of a sudden, precipitous drop in the value of our financed assets. Declines in the values of our financed assets could also require us to reduce our leverage by selling assets or not replacing MBS as they amortize and/or prepay, thereby decreasing the outstanding amount of our related borrowings. Even a small decrease in the value of a leveraged asset may require us to post additional collateral. The requirement to post additional collateral may decrease the amount of cash available to us for distributions to our shareholders, and deleveraging to manage declines in the values of our assets could reduce our interest income and interest expense, which could adversely affect our financial condition and results of operations.

For more information about our operating policies regarding leverage and historic leverage levels, please see “Liquidity and Capital Resources” within Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operation.”

Repurchase agreements are generally uncommitted short-term financings and changes to terms of such financing may adversely affect our profitability.

8

Repurchase agreements are generally uncommitted financings from lenders with an average term of ninety days or less. Because we rely heavily on borrowings under repurchase agreements to finance certain of our investments, our ability to achieve our investment and profitability objectives can depend on our ability to access repurchase agreement financing in sufficient amounts and on favorable terms, and to renew or replace maturing financings on a continuing basis. If the terms on which we borrow change in a meaningful way, our profitability may be negatively impacted which could reduce distributions to our shareholders.

We invest in assets that are traded in over-the-counter (OTC) markets which are less liquid and have less price transparency than securities exchanges. Owning securities that are traded in OTC markets may increase our liquidity risk, particularly in a volatile market environment, because our assets may be more difficult to borrow against or sell in a prompt manner and on terms acceptable to us, and we may not realize the full value at which we previously recorded the investments and/or may incur additional losses upon sale.

Though Agency MBS are generally deemed to be very liquid securities, turbulent market conditions in the past have at times significantly and negatively impacted the liquidity of these assets, resulting in reductions in their market value. Non-Agency MBS are typically more difficult to value, less liquid, and experience greater price volatility than Agency MBS. In addition, market values for non-Agency MBS are typically more subjective than Agency MBS. As a result of these factors, the number of lenders willing to provide financing for non-Agency MBS or accept them as collateral has generally been limited.

A sudden reduction in the liquidity of our investments could limit our ability to finance or could make it difficult to sell investments if the need arises. If we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the value at which we have previously recorded our investments which would result in lower than anticipated gains or higher losses.

Furthermore, repurchase agreements grant the respective lender the right to reevaluate the market value of the assets that secure outstanding borrowings at any time. If a lender determines that the value of the assets has declined below the lender's required haircut, it has the right to initiate a margin call. A margin call would require us to transfer additional assets to such lender or to repay a portion of the outstanding borrowings. Any such margin call could have a material adverse effect on our results of operations, financial condition, business, liquidity and ability to make distributions to stockholders, and could cause the value of our common stock or preferred stock to decline. We may be forced to sell assets at significantly depressed prices to meet margin calls and to maintain adequate liquidity, which could cause us to incur losses. Moreover, to the extent that we are forced to sell assets because of changes in market conditions, other market participants may face similar pressures, which could exacerbate a difficult market environment and which could result in significantly greater losses on our sale of such assets. In an extreme case of market duress, a market may not exist for certain of our assets at any price.

Fluctuations in interest rates may have various negative effects on us and could lead to reduced net interest income and a lower book value.

Fluctuations in interest rates impact us in a number of ways. For example, in a period of rising rates, we may experience a decline in our profitability from borrowing rates increasing faster than rates on our assets reset or from our investments adjusting less frequently or relative to a different index (e.g., six month or one-year LIBOR) from our borrowings (repurchase agreements are typically based on one-month LIBOR). Most of our assets are also fixed rate for a period of their lives and are financed with floating rate repurchase agreements that mature faster. In a period of rising rates our borrowings will reset more quickly to market interest rates than most of our assets, which may negatively affect returns on our portfolio and our net interest income.

Fluctuations in interest rates may also negatively affect the market value of our securities. Since our securities are fixed rate or adjust generally over longer-term periods, rising interest rates will reduce the market value of our MBS as a result of higher yield requirements by the market for these types of securities. In some instances, increases in short-term rates are rapid enough that short-term rates equal or exceed medium/long-term rates, resulting in a flat or inverted yield curve. Any fixed-rate or hybrid ARM investment will generally be more negatively affected by these increases than ARMs (which have interest-rates that adjust more frequently). Reductions in the market value of our securities could result in margin calls from our lenders, potentially forcing us to sell securities at a loss. Conversely, while declining interest rates are more favorable for us, we may experience increasing prepayments, resulting in reduced profitability due to reinvestment of our capital in lower yielding investments.

9

The mortgage loans collateralizing ARMs typically have periodic (or interim) and lifetime interest rate caps. Periodic interest rate caps limit the amount interest rates can adjust on a loan during any given period. Lifetime interest rate caps limit the amount interest rates can adjust from inception through maturity of a loan. Because of these caps, the amount of gross interest income earned by ARMs may become limited in a sustained period of rising interest rates or in any period in which interest rates rise rapidly. We may also experience price volatility as ARMs approach their interest rate caps. In addition, we could experience additional declines in net interest income as the repurchase agreements financing ARMs do not have periodic or lifetime interest rate caps.

A sudden shift in U.S. monetary policy may increase our borrowing costs and negatively impact the value of our investments and book value.

The Federal Open Market Committee (“FOMC”) of the Federal Reserve has maintained its targeted federal funds rate at the historically low range of between 0% and 0.25% since 2008. The FOMC has also sought to provide additional policy monetary stimulus with large-scale purchases of Treasury securities and Agency RMBS (which the market has referred to as quantitative easing, or "QE"). While the FRBNY, on behalf of the FOMC, is not actively purchasing additional securities under the QE program, it continues to reinvest principal repayments received on the securities which it owns in order to maintain an accommodative monetary policy.

The potential market volatility from the Federal Reserve's future withdrawal of its accommodative monetary policy through its reinvestment of principal payments received or increases in the targeted federal funds rate may be extreme. Once the Federal Reserve announces a higher targeted range or if markets determine that the Federal Reserve is likely to announce a higher targeted range, our borrowing costs are likely to increase which will negatively impact our results of operations and could impact our financial condition and book value. Further, significant price volatility could occur following large asset sales (or anticipation thereof) by the FRBNY. In such a case, it is likely that prices on our investments would decline which would cause a decline in our book value and also could result in margin calls by our lenders on Agency MBS pledged as collateral for repurchase agreements. If declines in prices are substantial, we could be forced to sell assets at a loss or at an otherwise inopportune time in order to meet margin calls or repay lenders.

Our repurchase agreements and derivative instruments may contain financial and non-financial covenants. Our inability to meet these covenants could adversely affect our financial condition, results of operations and cash flows.

In connection with certain of our repurchase agreements and derivative instruments, we are required to maintain certain financial and non-financial covenants. The most restrictive financial covenants as of February 28, 2015 require that, on any date, we have (i) a minimum of $30 million of liquidity; (ii) a minimum shareholders' equity of the sum of $110 million and 90% of all net capital contributions after June 30, 2008; (iii) declines in shareholders' equity less than 25% in any quarter and 35% in any year; and (iv) and a maximum debt-to-equity ratio of 7-to-1. In addition, virtually all of our repurchase agreements and derivative instruments require us to maintain our status as a REIT and to be exempted from the provisions of the 1940 Act. Compliance with these covenants depends on market factors and the strength of our business and operating results. Various risks, uncertainties and events beyond our control, including significant fluctuations in interest rates, could affect our ability to comply with these covenants. Failure to comply with these covenants could result in an event of default, termination of a repurchase agreement, acceleration of all amounts owing under a repurchase agreement, and generally would give the counterparty the right to exercise certain other remedies under the repurchase agreement, including the sale of the asset subject to repurchase at the time of default, unless we were able to negotiate a waiver in connection with any such default related to failure to comply with a covenant. Any such waiver could be conditioned on an amendment to the repurchase agreement and any related guaranty agreement on terms that may be unfavorable to us. If we are unable to negotiate a covenant waiver or replace or refinance our assets under a new repurchase facility on favorable terms or at all, our financial condition, results of operations and cash flows could be adversely affected. Further, certain of our repurchase agreements and derivative instruments have cross-default, cross-acceleration or similar provisions, such that if we were to violate a covenant under one agreement, that violation could lead to defaults, accelerations, or other adverse events under other agreements, as well.

Prepayment rates on the mortgage loans underlying our investments may adversely affect our profitability and the market value of our investments. Changes in prepayment rates may also subject us to reinvestment risk.

10

We are subject to prepayment risk to the extent that we own investments at premiums to their par value. Our investment portfolio consists substantially of RMBS and CMBS owned at premiums, and CMBS IO securities which have no principal amounts outstanding and consist only of the right to receive interest payments on the underlying pools of CMBS loans included in the securitization trust. Prepayments on our investments can occur both on a voluntary and involuntary (i.e., a loan default and subsequent foreclosure and liquidation) basis. Voluntary prepayments tend to increase when interest rates are declining or, in the case of ARMs or hybrid ARMs, based on the shape of the yield curve. CMBS and CMBS IO are generally protected from voluntary prepayment either by an absolute prepayment lock-out on the loan or by yield maintenance or prepayment penalty provisions which compensate us for future lost interest income on the loan. RMBS provide no specific protection from voluntary prepayment. The actual level of prepayments on our investments will be impacted by economic and market conditions, the absolute and relative levels of interest rates, and the general availability of mortgage credit among other factors. We have no protection from involuntary prepayments which tend to increase in periods of economic stress and may occur for any of our investment types.

We amortize the premiums we pay on a security using the effective yield method, which is impacted by actual and projected borrower prepayments of principal on the loans. If we experience actual prepayments in excess of our projections or increase our expectations of future prepayment activity, we will amortize investment premiums at an accelerated rate which would reduce our interest income. The impact of accelerated amortization is particularly acute on CMBS IO securities since these securities consist entirely of premium.

Increases in actual prepayment rates or market expectations of prepayment rates could also negatively impact the market value of our investments. Faster prepayments generally negatively impact the market value of RMBS due to less predictability of payments on the underlying mortgage loans and will increase the required market yield on such security. Faster prepayments will also negatively impact the market value of CMBS IO, depending on the amount of prepayment protection for a given security. Increasing prepayments will typically reduce the value of our securities owned at premiums which will negatively impact our book value. We are also more likely to experience margin calls from our lenders as a result of the decline in value of our securities.

In certain circumstances, compensation for voluntary prepayment on CMBS IO securities may not be sufficient to compensate us for the loss of future excess interest as a result of the prepayment, thereby adversely affecting our results of operations. Also, the amount of prepayment penalties on loans underlying CMBS and CMBS IO decline over time, and as loans age, interest rates decline, or market values of the collateral supporting the loan increase, prepayment penalties may not serve as a sufficient economic disincentive to prevent the borrower from prepaying.

If we receive increased prepayments of our principal in a declining or low interest rate environment, we may earn a lower return on our new investments as compared to the MBS that prepay given the declining interest rate environment. If we reinvest our capital in lower yielding investments, we will likely have lower net interest income and reduced profitability unless the cost of financing these investments declines faster than the rate at which we may reinvest.

Provisions requiring yield maintenance charges, prepayment penalties, defeasance, or lock-outs in CMBS IO securities may not be enforceable.

Provisions in loan documents for mortgages in CMBS IO securities in which we invest requiring yield maintenance charges, prepayment penalties, defeasance, or lock-out periods may not be enforceable in some states and under federal bankruptcy law. Provisions in the loan documents requiring yield maintenance charges and prepayment penalties may also be interpreted as constituting the collection of interest for usury purposes. Accordingly, we cannot be assured that the obligation of a borrower to pay any yield maintenance charge or prepayment penalty under a loan document in a CMBS IO security will be enforceable. Also, we cannot be assured that foreclosure proceeds under a loan document in a CMBS IO security will be sufficient to pay an enforceable yield maintenance charge. If yield maintenance charges and prepayment penalties are not collected, or if a lock-out period is not enforced, we may incur losses to write-down the value of the CMBS IO security for the present value of the amounts not collected. This would also likely cause margin calls from any lender on the CMBS IO impacted. Because a margin call would require us to transfer additional assets to such lender or to repay a portion of the outstanding borrowings, it could have a material adverse effect on our liquidity.

We invest in securities guaranteed by Fannie Mae and Freddie Mac which are currently under conservatorship by the Federal Housing Finance Agency (“FHFA”). As conservator, the FHFA has assumed all the powers of the shareholders, directors and officers of the GSEs with the goal of preserving and conserving their assets. Both Fannie Mae's and Freddie Mac's solvency

11

is being supported by the Treasury through their committed purchases of Fannie Mae and Freddie Mac preferred stock. The ultimate impact on the operations of Fannie Mae and Freddie Mac from the conservatorships and the support they receive from the U.S. government is not determinable and could affect Fannie Mae and Freddie Mac in such a way that our business, operations and financial condition may be adversely affected.

In 2008, the FHFA placed Fannie Mae and Freddie Mac under federal conservatorship. As its conservator, the FHFA has broad regulatory powers over Fannie Mae and Freddie Mac and has entered into Preferred Stock Purchase Agreements, as amended, (“PSPAs”) pursuant to which the Treasury ensures that Fannie Mae and Freddie Mac will separately maintain a positive net worth by committing to purchase preferred stock of Fannie Mae and Freddie Mac. The FHFA as the regulator of the GSEs has proposed several reforms including, among other things, building a common, single, securitization platform between the two entities and gradually contracting their presence in the mortgage marketplace. In addition, the U.S. Congress at various times has considered structural changes to the GSEs, including winding down the GSEs and replacing them with a privately capitalized system that is intended to preserve market liquidity and protect taxpayers from future GSE losses due to economic downturns.

The outcome of the conservatorship and the scope and nature of actions that may ultimately be taken by the U.S. Congress to reform the GSEs and the housing finance system, are not predictable at this point. Actions limiting the guarantee on future Agency MBS could impact the amount of Agency MBS available to be purchased which could lead to increased competition and reduced returns from these assets. It could also negatively impact our ability to comply with the provisions of the 1940 Act (see further discussion below regarding the 1940 Act).

Both Fannie Mae and Freddie Mac have returned to profitability as a result of the housing market recovery but their long-term financial viability is highly dependent on governmental support. If the Treasury withdraws its support, the value of Agency MBS could significantly decline, which would make it difficult for us to obtain repurchase agreement financing and could force us to sell assets at substantial losses. In addition, future policies that change the relationship between Fannie Mae and Freddie Mac and the U.S. government, including those that result in their winding down, nationalization, privatization, or elimination, may create market uncertainty and have the effect of reducing the actual or perceived credit quality of securities issued or guaranteed by Fannie Mae and Freddie Mac. As a result, such policies could increase the risk of loss on investments in Agency MBS. It also is possible that such policies could adversely impact the market for such securities and spreads at which they trade, and thereby adversely impact the profitability of our investments.

All of the foregoing could materially adversely affect the availability, pricing, liquidity, market value and financing of our assets and materially adversely affect our business, operations and financial condition.

Global sovereign credit risk could have a material adverse effect on our business, financial condition and liquidity.

Sovereign credit in the United States and Europe is currently under pressure as a result of large budget deficits, fiscal imbalances and below trend growth or negative growth. While we do not borrow directly from any sovereign, global risk appetite is impacted by changes in actual or perceived credit risk of the United States, Europe and Asia. Adverse changes in sovereign credit ratings could have a material adverse impact on financial markets and economic conditions in the United States and worldwide, and on the availability of financing as well as the price of securities that we own. Any such adverse impact could have a material adverse effect on our liquidity, financial condition and results of operations.

In addition, since Fannie Mae and Freddie Mac are under conservatorship of the U.S. government which is supporting their solvency, it is unclear if any downgrade in the credit of the U.S. government would impact its ability to maintain the solvency of these entities. In such a case, the ability of Fannie Mae and Freddie Mac to perform pursuant to their guarantees on Agency MBS may be severely limited which could have a material adverse effect on our liquidity, financial condition and results of operations.

Our investment strategy includes investing in securities with credit risk. Many of these securities have some form of subordinate credit enhancement within the security structure. The performance of these securities is dependent in large part on the performance of the underlying mortgage loans relative to the amount of the subordinate credit enhancement within the security structure. These mortgage loans are subject to defaults, foreclosure timeline extension, fraud, price depreciation, and unfavorable modification of loan principal amount, interest rate, and premium, any of which could result in losses to us.

12

Mortgage-backed securities are secured by mortgage loans (generally single family residential properties for RMBS and pools of commercial mortgage loans for CMBS). We own securities that generally have some form of credit subordination to our investment with respect to credit losses on the underlying mortgage loans. We bear a risk of loss of principal on our security to the extent losses experienced on the loans in these securities are in excess of such subordination.

CMBS and CMBS IO securities that we own have a wide range of subordination levels and are collateralized by pools of commercial mortgage loans secured by multifamily or commercial properties. Commercial mortgage loans generally have a higher principal balance and the ability of a borrower to repay a loan secured by an income-producing property typically is dependent upon the successful operation of the property rather than upon the existence of independent income or assets of the borrower. If the net operating income of a commercial property is reduced, the borrower's ability to repay the loan may be impaired. Net operating income of an income-producing property can be affected by, among other things, economic conditions, tenancy, location and condition, property management decisions, competition, regulations, environmental conditions, occupancy rates, interest rates and real estate tax rates and other operating expenses. Losses on underlying commercial mortgage loans will potentially impact the yield on the CMBS and CMBS IO securities we own and could also negatively impact their market value. Negative impacts on yields will reduce our net income and reductions in market values could lead to margin calls by our lenders which, if significant, could force us to sell assets possibly at losses to meet margin calls.

Similar to CMBS and CMBS IO, we own RMBS that generally have some form of credit subordination to our investment with respect to credit losses on the underlying mortgage loans. We bear a risk of loss of principal on our security to the extent losses are sufficient to eliminate such subordination. RMBS securities are generally collateralized by pools of single family mortgage loans which have less idiosyncratic risk than CMBS and CMBS IO. The ability of a borrower to repay a mortgage loan secured by a residential property is dependent upon the income or assets of the borrower. A number of factors may impair borrowers’ abilities to repay their loans, including among other things, their employment situation, economic conditions, and the availability of refinancing. In the event of defaults on the residential mortgage loans that underlie our investments in RMBS and the exhaustion of any underlying or any additional credit support, we may not realize our anticipated return on our investments and we may incur a loss on these investments.

For further discussion, see “Quantitative and Qualitative Disclosures About Market Risk” within Part II, Item 7A.

We may change our investment strategy, operating policies, dividend policy, and/or asset allocations without shareholder consent.

We may change our investment strategy, operating policies, dividend policy and/or asset allocation with respect to investments, acquisitions, leverage, growth, operations, indebtedness, capitalization and distributions at any time without the consent of our shareholders. A change in our investment strategy may increase our exposure to interest rate and/or credit risk, default risk and real estate market fluctuations. Furthermore, a change in our asset allocation could result in our making investments in asset categories different from our historical investments. These changes could adversely affect our financial condition, results of operations, the market price of our common stock or our ability to pay dividends to our shareholders.

Competition may prevent us from acquiring new investments at favorable yields, and we may not be able to achieve our investment objectives which may potentially have a negative impact on our profitability.

Our net income will largely depend on our ability to acquire mortgage-related assets with acceptable risk-return profiles at favorable spreads over our borrowing costs. The availability of mortgage-related assets meeting our investment criteria depends upon, among other things, the level of activity in the real estate market and the quality of and demand for securities in the mortgage securitization and secondary markets. The size and level of activity in real estate lending markets depends on various factors, including interest rates, regional and national economic conditions, and real estate values. In acquiring investments, we may compete with other purchasers of these types of investments, including but not limited to other mortgage REITs, broker-dealers, hedge funds, banks, savings and loans, insurance companies, mutual funds, and other entities that purchase assets similar to ours, many of which have greater financial resources than we do. As a result of all of these factors, we may not be able to acquire sufficient assets at acceptable spreads to our borrowing costs, which would adversely affect our profitability.

In order to maintain our portfolio size and our earnings, we must reinvest the cash flows we receive from our existing investment portfolio, including monthly principal and interest payments and proceeds from sales. If the assets we acquire in the

13

future earn lower yields than the assets we currently own, our reported earnings per share will likely decline over time as the older assets pay down or are sold. The risk that newly-acquired investments will not generate yields as attractive as yields on our current assets has been exacerbated in recent quarters due to the very low interest rate environment, Federal Reserve monetary policy, and increased competition for investment securities. In addition, based on market conditions, we may decide to not reinvest the cash flows we receive from our investment portfolio. If we retain, rather than reinvest, these cash flows, the size of our investment portfolio and the amount of net interest income generated by our investment portfolio will likely decline.

Our use of hedging strategies to mitigate our interest rate exposure may not be effective and may adversely affect our income and book value.

We use interest rate swap agreements, Eurodollar futures, interest rate caps, and other derivative transactions (collectively, “hedging instruments”) to help mitigate increased financing costs and volatility in book value from adverse changes in interest rates. Our hedging activity will vary in scope based on our portfolio construction and objectives, the actual and implied level and volatility of interest rates, our forecast of future interest rates, and financing sources used. No hedging strategy, however, can completely insulate us from the interest rate risks to which we are exposed, and there can be no assurance that the implementation of any hedging strategy will have the desired impact on our results of operations or financial condition. In addition, hedging instruments that we use may adversely affect our results of operations and book value (particularly if interest rates decline) as the fair value of hedging instruments fluctuate with changes in rates (and require us to post margin to counterparties) and also involve an expense that we will incur regardless of the effectiveness of the hedging activity.

Our hedging instruments can be traded on an exchange or administered through a clearing house, or are administered under bilateral agreements between us and a counterparty. Bilateral agreements expose us to increased counterparty risk, and we may be at risk of loss of any collateral held by a hedging counterparty if the counterparty becomes insolvent or files for bankruptcy.

Interest rate hedging may fail to protect or could adversely affect us because, among other things:

• The performance of instruments used to hedge may not completely correlate with the performance of the assets or liabilities being hedged;

• Interest rate hedging can be expensive, particularly during periods of volatile interest rates;

• Available hedging instruments may not correspond directly with the interest rate risk from which we seek protection;

• The duration of the hedge may not match the duration of the related asset or liability;

• The value of derivatives used for hedging will be adjusted from time to time in accordance with GAAP to reflect changes in fair value, and downward adjustments, or “mark-to-market losses,” would reduce our earnings, shareholders’ equity, and book value;

• The amount of income that a REIT may earn from hedging transactions (other than through taxable REIT subsidiaries) to offset interest rate losses may be limited by U.S. federal income tax provisions governing REITs;

• The credit quality of the party owing money on the hedge may be downgraded to such an extent that it impairs our ability to sell or assign our side of the hedging transaction; and

• The party owing money in the hedging transaction may default on its obligation to pay.

Our hedging transactions, which are intended to limit losses, may actually adversely affect our earnings, which could reduce our ability to pay dividends to our shareholders.

Clearing facilities or exchanges may increase the margin requirements we are required to post when entering into derivative instruments, which may negatively impact our ability to hedge and our liquidity.

We are required to post margin when entering into a hedging instrument which is traded on an exchange or administered through a clearing house. The amount of margin is set for each derivative by the exchange or clearinghouse and in prior periods, exchanges have required additional margin in response to events having or expected to have adverse economic consequences. For example, in response to the U.S. approaching its debt ceiling without resolution and the federal government shutdown in October 2013, the Chicago Mercantile Exchange announced that it would increase margin requirements by 12% for all over-the-counter interest rate swap portfolios that its clearinghouse guaranteed. This increase was subsequently rolled back shortly thereafter upon the news that Congress passed legislation to temporarily suspend the national debt ceiling. In the event that future adverse economic

14

developments or market uncertainty (including those due to governmental, regulatory, or legislative action or inaction) result in increased margin requirements for our hedging instruments, it could materially adversely affect our liquidity position, business, financial condition and results of operations.

We may be subject to the risks associated with inadequate or untimely services from third-party service providers, which may negatively impact our results of operations. We also rely on corporate trustees to act on behalf of us and other holders of securities in enforcing our rights.

Our loans and loans underlying non-Agency MBS we own are serviced by third-party service providers. These servicers provide for the primary and special servicing of our single-family and commercial mortgage loans and non-Agency MBS. In that capacity these service providers control all aspects of loan collection, loss mitigation, default management and ultimate resolution of a defaulted loan including as applicable the foreclosure and sale of the real estate owned. The servicer has a fiduciary obligation to act in the best interest of the securitization trust, but significant latitude exists with respect to certain of its servicing activities. We have no contractual rights with respect to these servicers, and our risk management operations may not be successful in limiting future delinquencies, defaults, and losses. If a third party servicer fails to perform its duties under the securitization documents, this may result in a material increase in delinquencies or losses on the MBS. As a result, the value of the MBS may be impacted, and we may incur losses on our investment.

In addition, should a servicer experience financial difficulties, it may not be able to perform its obligations. Due to application of provisions of bankruptcy law, servicers who have sought bankruptcy protection may not be required to make advance payments required under the terms of the MBS of amounts due from loan borrowers. Even if a servicer were able to advance amounts in respect of delinquent loans, its obligation to make the advances may be limited to the extent that is does not expect to recover the advances due to the deteriorating credit of the delinquent loans.

We also rely on corporate trustees to act on behalf of us and other holders of securities in enforcing our rights. Under the terms of most securities we hold we do not have the right to directly enforce remedies against the issuer of the security, but instead must rely on a trustee to act on behalf of us and other security holders. Should a trustee not be required to take action under the terms of the securities, or fail to take action, we could experience losses.

Credit ratings assigned to debt securities by the credit rating agencies may not accurately reflect the risks associated with those securities. Changes in credit ratings for securities we own or for similar securities might negatively impact the market value of these securities.

Rating agencies rate securities based upon their assessment of the safety of the receipt of principal and interest payments on the securities. Rating agencies do not consider the risks of fluctuations in fair value or other factors that may influence the value of securities and, therefore, the assigned credit rating may not fully reflect the true risks of an investment in securities. Also, rating agencies may fail to make timely adjustments to credit ratings based on available data or changes in economic outlook or may otherwise fail to make changes in credit ratings in response to subsequent events, so our investments may be better or worse than the ratings indicate. We attempt to reduce the impact of the risk that a credit rating may not accurately reflect the risks associated with a particular debt security by not relying solely on credit ratings as the indicator of the quality of an investment. We make our acquisition decisions after factoring in other information that we have obtained about the loans underlying the security and the credit subordination structure of the security. Despite these efforts, our assessment of the quality of an investment may also prove to be inaccurate and we may incur credit losses in excess of our initial expectations.

Credit rating agencies may change their methods of evaluating credit risk and determining ratings on securities backed by real estate loans and securities. These changes may occur quickly and often. The market’s ability to understand and absorb these changes, and the impact to the securitization market in general, are difficult to predict. Such changes may have a negative impact on the value of securities that we own.

If a lender to us in a repurchase transaction defaults on its obligation to resell the underlying security back to us at the end of the transaction term, or if we default on our obligations under a repurchase agreement, we will incur losses.

Repurchase agreement transactions are legally structured as the sale of a security to a lender in return for cash from the lender. These transactions are accounted for as financing agreements because the lenders are obligated to resell the same securities

back to us at the end of the transaction term. Because the cash we receive from the lender when we initially sell the securities to the lender is less than the value of those securities, if the lender defaults on its obligation to resell the same securities back to us, we would incur a loss on the transaction equal to the difference between the value of the securities sold and the amount borrowed from the lender. The lender may default on its obligation to resell if it experiences financial difficulty or if the lender has re-hypothecated the security to another party who fails to transfer the security back to the lender. Additionally, if we default on one of our obligations under a repurchase agreement, the lender can terminate the transaction, sell the underlying collateral and cease entering into any other repurchase transactions with us. Any losses we incur on our repurchase transactions could adversely affect our earnings and reduce our ability to pay dividends to our shareholders.

In the event of bankruptcy either by ourselves or one or more of our third party lenders, under the U.S. Bankruptcy Code, assets pledged as collateral under repurchase agreements may not be recoverable by us. We may incur losses equal to the excess of the collateral pledged over the amount of the associated repurchase agreement borrowing.

In the event that one of our lenders under a repurchase agreement files for bankruptcy, it may be difficult for us to recover our assets pledged as collateral to such lender. In addition, if we ever file for bankruptcy, lenders under our repurchase agreements may be able to avoid the automatic stay provisions of the U.S. Bankruptcy Code and take possession of and liquidate our collateral under our repurchase agreements without delay. In the event of a bankruptcy by one of our lenders, or us, we may incur losses in amounts equal to the excess of our collateral pledged over the amount of repurchase agreement borrowing due to the lender.

If we fail to properly conduct our operations we could become subject to regulation under the 1940 Act. Conducting our business in a manner so that we are exempt from registration under and compliance with the 1940 Act may reduce our flexibility and could limit our ability to pursue certain opportunities.

We seek to conduct our operations so as to avoid falling under the definition of an investment company pursuant to the 1940 Act. Specifically, we seek to conduct our operations under the exemption provided under Section 3(c)(5)(C) of the 1940 Act, a provision available to companies primarily engaged in the business of purchasing and otherwise acquiring mortgages and other liens on and interests in real estate. According to SEC no-action letters, companies relying on this exemption must ensure that at least 55% of their assets are mortgage loans and other qualifying assets, and at least 80% of their assets are real estate-related. The 1940 Act requires that we and each of our subsidiaries evaluate our qualification for exemption under the Act. Our subsidiaries will rely either on Section 3(c)(5)(C) or other sections that provide exemptions from registering under the 1940 Act, including Sections 3(a)(1)(C) and 3(c)(7). The SEC is currently reviewing the Section 3(c)(5)(C) exemption as further discussed below. We believe that we are operating our business in accordance with the exemption requirements of Section 3(c)(5)(C).

Under the 1940 Act, an investment company is required to register with the SEC and is subject to extensive restrictive and potentially adverse regulations relating to, among other things, operating methods, management, capital structure, dividends, and transactions with affiliates. If we were determined to be an investment company, our ability to use leverage and conduct business as we do today would be substantially impaired.

In August 2011, the SEC initiated a review of Section 3(c)(5)(C) of the 1940 Act and the regulations and regulatory interpretations promulgated thereunder. We rely on Section 3(c)(5)(C) as an exemption from registration and regulation under the 1940 Act and any regulatory changes as a result of this SEC review could require us to change our business and operations.

On August 31, 2011, the SEC issued a concept release relating to the exclusion from registration as an investment company provided to mortgage companies by Section 3(c)(5)(C) of the 1940 Act. This release raises concerns regarding the ability of mortgage REITs to continue to rely on the exclusion in the future. In particular, the release states the SEC is concerned that certain types of mortgage-related pools today appear to resemble in many respects investment companies such as closed-end funds and may not be the kinds of companies that were intended to be excluded from regulation under the 1940 Act by Section 3(c)(5)(C).

Although we believe that we are properly relying on Section 3(c)(5)(C) to exempt us from regulation under the 1940 Act (which belief in large part is based on no-action letters issued by the SEC with respect to operations of other mortgage REITs), the SEC review could eventually affect our ability to rely on that exemption or could eventually require us to change our business and operations in order for us to continue to rely on that exemption. If the SEC changes or narrows this exemption, we could be required to sell a substantial amount of our MBS under potentially adverse market conditions, which could have a material adverse

16

effect on our financial condition and results of operations. We could also be forced to materially alter our business model and investment strategies which could materially and adversely affect our profitability.

The outcome of the review by the SEC at this time is not determinable, and the SEC may take no action as a result of its review of the Section 3(c)(5)(C) exemption from the 1940 Act. It is also possible that the SEC issues interpretative guidance for mortgage REITs as to how their operations must be structured in order to avoid being considered an investment company, and compliance with any such guidance could limit our operations and our profitability as indicated above. Finally, it is possible that the SEC requires mortgage REITs to be considered investment companies and to register under the 1940 Act which would severely limit our operations and profitability and likely have a material adverse effect on our financial condition and results of operations.

If we fail to abide by certain Commodity Futures Trading Commission (“CFTC”) rules and regulations, we may be subject enforcement action by the CFTC.

On December 7, 2012, the CFTC’s Division of Swap Dealer and Intermediary Oversight (the “Division”) issued no-action relief from commodity pool operator (“CPO”) registration to mortgage REITs that use CFTC-regulated products (“commodity interests”) and that satisfy certain enumerated criteria. Pursuant to the no-action letter, the Division will not recommend that the CFTC take enforcement action against a mortgage REIT if its operator fails to register as a CPO, provided that the mortgage REIT (i) submits a claim to take advantage of the relief and (ii) the mortgage REIT: (a) limits the initial margin and premiums required to establish its commodity interest positions to no greater than 5 percent of the fair market value of the mortgage REIT’s total assets; (b) limits the net income derived annually from its commodity interest positions, excluding the income from commodity interest positions that are “qualifying hedging transactions,” to less than 5 percent of its annual gross income; (c) does not market interests in the mortgage REIT to the public as interests in a commodity pool or otherwise in a vehicle for trading in the commodity futures, commodity options or swaps markets; and (d) either: (A) identified itself as a “mortgage REIT” in Item G of its last U.S. income tax return on Form 1120-REIT; or (B) if it has not yet filed its first U.S. income tax return on Form 1120-REIT, it discloses to its shareholders that it intends to identify itself as a “mortgage REIT” in its first U.S. income tax return on Form 1120-REIT.

We believe that we have complied with all of the requirements set forth above as of and for the year ended December 31, 2014. If we fail to satisfy the criteria set forth above, or if the criteria change, we may become subject to CFTC regulation or enforcement action, the consequences of which could have a material adverse effect on our financial condition or results of operations.

RISKS RELATED TO REGULATORY POLICY

The Federal Reserve and other U.S. regulators have adopted regulations to improve the financial strength of the U.S. and international banking systems. Such regulation has limited certain activities of banks and other financial institutions and also has increased liquidity and capitalization requirements, particularly those applied to the largest financial institutions. U.S. regulators have recently introduced capitalization standards for U.S. domiciled broker dealers of foreign banks. When fully implemented, these regulations and capitalization standards may impact the future availability of repurchase agreement financing which could impact our business model and adversely affect our financial conditions and results of operations.

During 2014 U.S. banking regulators and the Basel Committee on Banking Supervision (the “Basel Committee”) took steps to require financial institutions, and particularly the largest bank holding companies and their subsidiary banks and affiliates, to strengthen their funding and leverage positions in an effort to address factors that contributed to financial distress from 2007 through 2009. Several recently adopted regulations and rules that are expected to be proposed may significantly impact the future availability of repurchase agreement financing, which could impact our business model.

U.S. banking regulators adopted final rules in 2014 to implement a supplemental leverage ratio (“SLR”) and a liquidity coverage ratio (“LCR”). The SLR applies to U.S. bank holding companies with $700 billion or more in consolidated assets, or over $10 trillion in assets under custody, and their bank subsidiaries. The SLR requires that a covered institution maintain a regulatory leverage buffer of 2% above the minimum leverage ratio that is otherwise required (3%), for a total of 5%, and covered bank subsidiaries must maintain a 6% leverage ratio to be considered well-capitalized. The LCR applies to all banking organizations with $250 billion or more in total consolidated assets, or $10 billion or more in foreign exposure on the organization’s balance

17

sheet, and a less stringent LCR applies to a banking organization with $50 billion or more in consolidated assets that does not meet the other tests. The LCR creates a minimum liquidity standard that requires a banking organization to hold high quality, liquid assets that would meet net cash outflows during a 30-day stress period. The SLR will be effective on January 1, 2018 and the LCR will be effective on January 1, 2017.

In addition, during 2014 the Basel Committee finalized a net stable funding ratio (NSFR) that requires banking organizations to maintain stable funding, as measured on a long-term funding horizon. The NSFR is designed to address funding and maturity mismatches. If adopted and implemented by banking regulators, including those in the U.S., the NSFR would most likely apply to internationally active banking organizations on a consolidated basis, and could also apply to other large domestic banking organizations. The NSFR requires a covered banking organization to obtain and rely more on funding sources that are stable and longer-term in nature as a regulatory tool to reduce a banking organization’s reliance on more unstable, short-term funding (including short-term wholesale funding), which the Basel Committee believes may become endangered as a funding source during periods of significant economic stress. If applied in combination, the NSFR and the LCR could significantly impact a banking organization’s short-term liquidity and longer-term liquidity requirements, funding sources and funding risks. The U.S. banking regulators are currently expected to propose rules to implement the NSFR during 2015.

The complete impact of the SLR and the LCR, when fully implemented, and the NSFR, if adopted by the U.S. banking regulators and when fully implemented, is not currently known. Application of these regulatory requirements and ratios would impact the leverage and funding profiles of large financial institutions and their affiliates, including many broker-dealers and other subsidiaries that are affiliated with large banking organizations and from which we obtain financing, and could lead to an increase in our cost of financing and reduce the amount of repurchase agreement financing made available to the financing markets.

In addition to the SLR, and LCR, and the NSFR if adopted, the Federal Reserve has adopted rules that will require foreign bank holding companies with combined U.S. assets of more than $50 billion to establish an intermediate holding company (“IHC”) that is headquartered in the U.S. over the company’s U.S. subsidiaries. Any such IHC will be subject to regulatory capital and leverage requirements, including the SLR and LCR, and the NSFR if adopted, subject to meeting relevant asset thresholds, as well as regulatory capital planning and stress testing requirements. This increased regulatory oversight could further limit the repurchase agreement financing made available by these foreign IHCs and their subsidiaries and affiliates, which could further increase our cost of financing. If the SLR, LCR or NSFR, including the application of these ratios to IHCs, causes the availability of repurchase agreement financing to decline, we may have fewer financing options in the future which could lead to lower profitability and could adversely affect our financial condition.

Recently adopted rules for money market funds could impact our access to funding for our non-Agency MBS which could negatively impact our business and results of operations.

During 2014 the SEC adopted amendments to the rules that govern money market mutual funds which made structural and operational reforms intended to address risks of investor runs in certain of these funds. The new rules require a floating net asset value (NAV) for institutional prime money market funds, which means that the daily share prices of these funds will fluctuate along with changes in the market-based value of fund assets. The new rules also provide non-government money market funds with new tools to address liquidity runs on the funds including the ability to charge fees and to temporarily suspend redemptions (also known as a redemption gate) during periods of extreme market stress.

With a floating NAV, institutional prime money market funds are required to value their portfolio securities using market-based factors and sell and redeem shares based on a floating NAV instead of allowing the funds to maintain a constant share price of $1.00. With liquidity fees and redemption gates, money market fund boards have the ability to impose fees and gates during periods of stress. The new rules will be effective in various stages over a two-year transition period, with the rules implementing the floating NAV, liquidity fee and redemption gate provisions effective in October 2016.

Money market funds provide substantial liquidity to the repurchase agreement markets. The impact of the changes to the regulatory structure of institutional prime money market funds is not yet known, but it is possible that the new SEC rules may lead to reduced availability of liquidity to the repurchase agreement markets which in turn could lead to an increase in our funding costs.

18

The effect of legislative and regulatory changes, including the Dodd-Frank Act and regulations implementing it, on our business, the mortgage industry and the markets in which we invest is uncertain, and may be adverse to our business, results of operations and financial condition.

The Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, was signed into law in July 2010, and significantly changes the regulation of financial institutions and the financial services industry, including the mortgage industry. The Dodd-Frank Act tasks many agencies with issuing a variety of new regulations, including rules related to mortgage origination and servicing, securitization and derivatives. Because a number of regulations under the Dodd-Frank Act have yet to be proposed,adopted or fully implemented, it is not yet known how these additional regulations will ultimately affect the borrowing environment, the investing environment for MBS, or interest rate swaps and other derivatives. Consequently, it is not possible for us to predict how additional regulations will affect our business, and there can be no assurance that these regulations will not have an adverse impact on our business, results of operations or financial condition.

In addition, there is an ongoing debate over the degree and kind of regulation that should be applied to entities that participate in what is popularly referred to as “shadow banking.” While there is no authoritative definition of what “shadow banking” is, it generally refers to financial intermediation involving entities and activities outside of the traditional depositary banking system, such as mortgage REITs, repurchase agreement financing, securitizations, private equity funds and hedge funds. A general policy concern is that an aspect or component of shadow banking that is not subject to banking regulation - such as safety and soundness regulation and capital requirements - or other government oversight could be a source of financial instability or pose systemic risk to the broader banking and financial markets.

In August 2013, the Financial Stability Board, an international body of which the United States is a member, issued policy recommendations to strengthen oversight and regulation of shadow banking. The policy recommendations outlined initial steps to define the scope of the shadow banking system and proposed general governing principles for a monitoring and regulatory framework, including a "toolkit" of potential regulatory responses that national regulators could employ to reduce systemic risk. While at this stage it is difficult to predict the type and scope of any new regulations that may be adopted by member countries, including the United States, if such regulations were to extend the regulatory and supervisory requirements currently applicable to banks, such as capital and liquidity standards, to our business or that of our financing counterparties or mortgage originators, or were to otherwise classify all or a portion of our business (including financing strategy) as shadow banking, our regulatory and operating costs, particularly borrowing costs, could increase, which may have a material adverse effect on our business.

The Federal Reserve and other banking regulators continue to explore regulatory initiatives that could impact complex transactions, or complex series of transactions, that relate to shadow banking and related financing markets. Many of these initiatives that are subject to preliminary discussions would, like the SLR and the LCR, aim to combat the build-up of leverage at, and the offer of leveraged financing by, large financial institutions. Series of transactions that transform short-term maturities into longer-term assets are subject to particular focus during these discussions. At this stage, it is impossible to predict what regulations may be imposed, by which regulator, on which segment of shadow banking, and with what effect. However, any regulations that successfully restrict the shadow banking system or repurchase agreement financing markets may have a material negative affect on our financial condition, results of operations and investment and financing.

The Treasury and Congress continue to seek ways to support the U.S. housing market and the overall U.S. economy, including seeking ways to make it easier to refinance loans owned or guaranteed by Fannie Mae or Freddie Mac where the borrower may have negative equity. In addition, mortgage loan modification programs and future legislative action may adversely affect the value of and the return on Agency RMBS securities in which we invest. Since we own our Agency RMBS at premiums to their par balance, we could incur substantial losses on our Agency RMBS if mortgage loan refinancings increased.

The Treasury and the Department of Housing and Urban Development ("HUD") have implemented the Home Affordable Refinance Program (or "HARP"), which allows borrowers who are current on their mortgage payments to refinance loans originated on or before May 31, 2009, with current loan-to-value ratios exceeding 80%, in order to reduce their monthly mortgage payments. HARP specifically targets borrowers that are current on their mortgage payment but who have negative equity in their home and, as a result, have been unable to refinance into a lower cost mortgage (given the decline in current mortgage rates compared to pre-May 31, 2009). HUD also recently announced a reduction in mortgage insurance premiums effective January 26, 2015, which could further encourage some homeowners to refinance existing mortgages. If refinance activity increases for Agency RMBS as a result of these or other government programs or efforts, or if we increase forecasted prepayments on our Agency RMBS, our net

19

interest income would be negatively impacted by the additional amortization of premium on our Agency RMBS. In addition, we may experience significant volatility in the market value of Agency RMBS as the market resets prepayment expectations on Agency RMBS. Such volatility could lead to margin calls from our repurchase agreement lenders and could force us to sell these securities under unfavorable conditions and possibly at a loss.

The Treasury and HUD have also created a number of different programs intended to assist borrowers that are struggling to make their mortgage payment that may involve, among other things, the modification of mortgage loans to reduce the principal amount of the loans (through forbearance and/or forgiveness) and/or the rate of interest payable on the loans, or to extend the payment terms of the loans. Loan modifications such as these could result in our ultimately receiving less than we are contractually due on certain of our investments. A significant number of loan modifications with respect to a given security could negatively impact the realized yields and cash flows on such security. These loan modification programs, future legislative or regulatory actions, including new mortgage loan modification programs and possible amendments to the bankruptcy laws, which result in the modification of outstanding residential mortgage loans, as well as changes in the requirements necessary to qualify for refinancing mortgage loans with Fannie Mae, Freddie Mac or Ginnie Mae, may adversely affect the value of, and the returns on, our securitized single-family mortgage loans and Agency RMBS.

RISKS RELATED TO OUR TAXATION AS A REIT AND OTHER TAX RELATED MATTERS

Qualifying as a REIT involves highly technical and complex provisions of the Code, and a technical or inadvertent violation could jeopardize our REIT qualification. Maintaining our REIT status may reduce our flexibility to manage our operations.

Qualification as a REIT involves the application of highly technical and complex Code provisions for which only limited judicial and administrative authorities exist. Even a technical or inadvertent violation could jeopardize our REIT qualification. Our qualification as a REIT will depend on our satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. Our operations and use of leverage also subjects us to interpretations of the Code, and technical or inadvertent violations of the relevant requirements under the Code could cause us to lose our REIT status or to pay significant penalties and interest. In addition, our ability to satisfy the requirements to qualify as a REIT depends in part on the actions of third parties over which we have no control or only limited influence, including in cases where we own an equity interest in an entity that is classified as a partnership for U.S. federal income tax purposes.

Maintaining our REIT status may limit flexibility in managing our operations. For instance:

• If we make frequent asset sales from our REIT entities to persons deemed customers, we could be viewed as a “dealer,” and thus subject to 100% prohibited transaction taxes or other entity level taxes on income from such transactions.

• Compliance with the REIT income and asset requirements may limit the type or extent of hedging that we can undertake.

• Our ability to own non-real estate related assets and earn non-real estate related income is limited. Our ability to own equity interests in other entities is limited. If we fail to comply with these limits, we may be forced to liquidate attractive assets on short notice on unfavorable terms in order to maintain our REIT status.

• Our ability to invest in taxable subsidiaries is limited under the REIT rules. Maintaining compliance with this limitation could require us to constrain the growth of future taxable REIT affiliates.

• Notwithstanding our NOL carryforward, meeting minimum REIT dividend distribution requirements could reduce our liquidity. Earning non-cash REIT taxable income could necessitate our selling assets, incurring debt, or raising new equity in order to fund dividend distributions.

• Stock ownership tests may limit our ability to raise significant amounts of equity capital from one source.

If we fail to maintain our REIT status, our ability to utilize repurchase agreements as a source of financing and to enter into interest rate swap agreements may be impacted.

Most of our repurchase agreements and the agreements governing our interest rate swaps require that we maintain our REIT status as a condition to engaging in a transaction with us. Even though repurchase agreements generally are not committed facilities with our lenders, if we failed to maintain our REIT status our ability to enter into new repurchase agreement transactions

20

or renew existing, maturing repurchase agreements will likely be limited. Some of our repurchase agreements and swap agreements have cross-default provisions which provide for lenders to terminate these agreements if we default under any of our repurchase agreements or swap agreements. As such, we may be required to sell investments, potentially under adverse circumstances, that were previously financed with repurchase agreements and we may be forced to terminate our interest rate swap agreements.

If we do not qualify as a REIT or fail to remain qualified as a REIT, we may be subject to tax as a regular corporation and could face a tax liability, which would reduce the amount of cash available for distribution to our shareholders.

We intend to operate in a manner that will allow us to qualify as a REIT for federal income tax purposes. Our qualification as a REIT will depend on our satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. Our ability to satisfy the asset tests depends upon our analysis of the characterization and fair market values of our assets, some of which are not susceptible to a precise determination, and for which we will not obtain independent appraisals. Our compliance with the REIT income and quarterly asset requirements also depends upon our ability to successfully manage the composition of our income and assets on an ongoing basis.

If we were to fail to qualify as a REIT in any taxable year, we would be subject to federal income tax, after consideration of our NOL carryforward but not considering any dividends paid to our shareholders during the respective tax year. If we could not otherwise offset this taxable income with our NOL carryforward, the resulting corporate tax liability could be material to our results and would reduce the amount of cash available for distribution to our shareholders, which in turn could have an adverse impact on the value of our common stock. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from taxation as a REIT until the fifth taxable year following the year for which we failed to qualify as a REIT.

Our future use of our tax NOL carryforward is limited under Section 382 of the Code, which could result in higher taxable income and greater distribution requirements in order to maintain our REIT status. Further, if we unknowingly undergo another ownership change pursuant to Section 382, or miscalculate the limitations imposed by a known ownership change, and utilize an impermissible amount of the NOL, we may fail to meet the distribution requirements of a REIT and therefore we could lose our REIT status.

We can use our tax NOL carryforward to offset our taxable earnings after taking the REIT distribution requirements into account. Section 382 of the Code limits the amount of NOL that could be used to offset taxable earnings after an “ownership change” occurs. A Section 382 ownership change generally occurs if one or more shareholders who own at least 5% of our stock, or certain groups of shareholders, increase their aggregate ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period.

Our public offering of common stock in February 2012 resulted in an ownership change under Section 382. Based on management's analysis and expert third-party advice, which necessarily includes certain assumptions regarding the characterization under Section 382 of our use of capital raised by us, we determined that the ownership change under Section 382 will limit our ability to use our NOL carryforward to offset our taxable income to an estimated maximum amount of $13.5 million per year. Because NOLs generally may be carried forward for up to 20 years, this annual limitation may effectively limit the cumulative amount of pre-ownership change losses, including certain recognized built-in losses, that we may utilize. This would result in higher taxable income and greater distribution requirements in order to maintain REIT qualification than if such limitation were not in effect.

We may incur additional ownership changes under Section 382 in the future, in which case the use of our NOL could be further limited. Future issuances or sales of our stock (including transactions involving our stock that are out of our control) could result in an ownership change under Section 382. If further ownership changes occur, Section 382 would impose stricter annual limits on the amount of pre-ownership change NOLs and other losses we could use to reduce our taxable income.

If we unknowingly undergo another ownership change under Section 382, or miscalculate the limitations imposed by a known ownership change, the use of the NOL could be limited more than we have determined and we may utilize (or may have utilized) more of the NOL than we otherwise may have been allowed. In such an instance we may be required to pay taxes, penalties and interest on the excess amount of NOL used, or we may be required to declare a deficiency dividend to our shareholders for the excess amount. In addition, if any impermissible use of the NOL led to a failure to comply with the REIT distribution requirements, we could fail to qualify as a REIT.

21

The failure of investments subject to repurchase agreements to qualify as real estate assets could adversely affect our ability to qualify as a REIT.

Repurchase agreement financing arrangements are structured legally as a sale and repurchase whereby we sell certain of our investments to a counterparty and simultaneously enter into an agreement to repurchase these securities at a later date in exchange for a purchase price. Economically, these agreements are financings which are secured by the investments sold pursuant thereto. We believe that we would be treated for REIT asset and income test purposes as the owner of the securities that are the subject of any such sale and repurchase agreement, notwithstanding that such agreements may legally transfer record ownership of the securities to the counterparty during the term of the agreement. It is possible, however, that the IRS could assert that we did not own the securities during the term of the sale and repurchase agreement, in which case we could fail to qualify as a REIT.

Even if we remain qualified as a REIT, we may face other tax liabilities that reduce our cash flow and our profitability.

Even if we remain qualified for taxation as a REIT, we may be subject to certain federal, state and local taxes on our income and assets, including taxes on any undistributed income, tax on income from some activities conducted as a result of a foreclosure or considered prohibited transactions under the Code, and state or local income taxes. Any of these taxes would decrease cash available for distribution to our shareholders. In addition, in order to meet the REIT qualification requirements, or to avert the imposition of a 100% tax that applies to certain gains derived by a REIT from prohibited transactions, we may hold some of our assets through a taxable REIT subsidiary (“TRS”) or other subsidiary corporations that will be subject to corporate-level income tax at regular rates to the extent that such TRS does not have an NOL carryforward. Any of these taxes would decrease cash available for distribution to our shareholders.

Recognition of excess inclusion income by us could have adverse consequences to us or our shareholders.

Certain of our securities have historically generated excess inclusion income and may continue to do so in the future. Certain categories of shareholders, such as foreign shareholders eligible for treaty or other benefits, shareholders with NOLs, and certain tax-exempt shareholders that are subject to unrelated business income tax, could be subject to increased taxes on a portion of their dividend income from us that is attributable to excess inclusion income. In addition, to the extent that our stock is owned by tax-exempt “disqualified organizations,” such as certain government-related entities and charitable remainder trusts that are not subject to tax on unrelated business income, we may incur a corporate level tax on a portion of our income. In that case, we may reduce the amount of our distributions to any disqualified organization whose stock ownership gave rise to the tax.

Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends.

The maximum tax rate applicable to income from “qualified dividends” payable to domestic shareholders that are individuals, trusts and estates may be either15% or 20%, depending on whether the taxpayer's income exceeds the threshold for the newly enacted 39.6% income tax bracket. Dividends payable by REITs, however, generally are not eligible for the reduced rates. Although this legislation does not adversely affect the taxation of REITs or dividends payable by REITs, the more favorable rates applicable to regular corporate qualified dividends could cause investors who are individuals, trusts and estates to perceive investments in REITs to be relatively less attractive than investments in the stocks of non-REIT corporations that pay dividends, which could adversely affect the value of the stock of REITs, including our common stock.

RISKS RELATED TO OUR CORPORATE STRUCTURE

The stock ownership limit imposed by the Code for REITs and our Articles of Incorporation may restrict our business combination opportunities. The stock ownership limitation may also result in reduced liquidity in our stock and may result in losses to an acquiring shareholder.

To qualify as a REIT under the Code, not more than 50% in value of our outstanding stock may be owned, directly or indirectly, by five or fewer individuals (as defined in the Code to include certain entities) at any time during the last half of each taxable year after our first year in which we qualify as a REIT. Our Articles of Incorporation, with certain exceptions, authorize our Board of Directors to take the actions that are necessary and desirable to qualify as a REIT. Pursuant to our Articles of

22

Incorporation, no person may beneficially or constructively own more than 9.8% of our capital stock (including our common stock, Series A Preferred Stock, and Series B Preferred Stock). Our Board of Directors may grant an exemption from this 9.8% stock ownership limitation, in its sole discretion, subject to such conditions, representations and undertakings as it may determine are reasonably necessary.

The ownership limits imposed by the tax law are based upon direct or indirect ownership by “individuals,” but only during the last half of a tax year. The ownership limits contained in our Articles of Incorporation apply to the ownership at any time by any “person,” which includes entities, and are intended to assist us in complying with the tax law requirements and to minimize administrative burdens. However, these ownership limits might also delay or prevent a transaction or a change in our control that might involve a premium price for our stock or otherwise be in the best interest of our shareholders.

Whether we would waive the ownership limitation for any other shareholder will be determined by our Board of Directors on a case by case basis. Our Articles of Incorporation’s constructive ownership rules are complex and may cause the outstanding stock owned by a group of related individuals or entities to be deemed to be constructively owned by one individual or entity. As a result, the acquisition of less than these percentages of the outstanding stock by an individual or entity could cause that individual or entity to own constructively in excess of these percentages of the outstanding stock and thus be subject to the ownership limit. The Board of Directors has the right to refuse to transfer any shares of our capital stock in a transaction that would result in ownership in excess of the ownership limit. In addition, we have the right to redeem shares of our capital stock held in excess of the ownership limit.

The stock ownership limit imposed by the Code for REITs and our Articles of Incorporation may impair the ability of holders to convert shares of our Series A Preferred Stock or Series B Preferred Stock into shares of our common stock upon a change of control.

The terms of our Series A Preferred Stock and Series B Preferred Stock provide that, upon occurrence of a change of control (as defined in the Articles of Incorporation), each holder of Series A Preferred Stock or Series B Preferred Stock will have the right (unless, prior to the Change of Control Conversion Date (as defined herein), we provide notice of our election to redeem the Series A Preferred Stock or Series B Preferred Stock, as applicable) to convert all or part of the Series A Preferred Stock and Series B Preferred Stock held by such holder on the Change of Control Conversion Date into a number of shares of our common stock per share of Series A Preferred Stock or Series B Preferred Stock, respectively, based on formulas set forth in our Articles of Incorporation. However, the stock ownership restrictions in our Articles of Incorporation also restrict ownership of shares of our Series A Preferred Stock and Series B Preferred Stock. As a result, no holder of Series A Preferred Stock or Series B Preferred Stock will be entitled to convert such stock into our common stock to the extent that receipt of our common stock would cause the holder to exceed the ownership limitations contained in our Articles of Incorporation, endanger the tax status of one or more real estate mortgage investment conduits ("REMICs") in which we have or plan to have an interest, or result in the imposition of a direct or indirect penalty tax on us. These provisions may limit the ability of a holder of Series A Preferred Stock or Series B Preferred Stock to convert shares of Series A Preferred Stock or Series B Preferred Stock into our common stock upon a change of control, which could adversely affect the market price of shares of our Series A Preferred Stock or of our Series B Preferred Stock.

We lease one facility located at 4991 Lake Brook Drive, Suite 100, Glen Allen, Virginia 23060 which provides 9,350 square feet of office space for our executive officers and employees. The term of the lease expires in March 2020, but may be renewed at our option for four additional periods of one year each at a rental rate 2.5% greater than the rate in effect during the preceding 12-month period or for one additional five-year period at the fair market rental rate for the time period such determination is being made for office space of comparable condition and location.

ITEM 3. LEGAL PROCEEDINGS

The Company and its subsidiaries are parties to various legal proceedings, including those described below.  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 described below could have a material impact on consolidated results of operations or cash flows in a given future reporting period as the proceedings are resolved.

One of the Company's subsidiaries, GLS Capital, Inc. ("GLS"), the County of Allegheny, Pennsylvania ("Allegheny County"), and the Company are named defendants in a putative class action lawsuit filed in June 2012 in the Court of Common Pleas of Allegheny County, Pennsylvania (the “Court”). Between 1995 and 1997, GLS purchased from Allegheny County delinquent property tax lien receivables for properties located in the county. The purported class in this action consists of owners of real estate in Allegheny County whose property is or has been subject to a tax lien filed by Allegheny County that Allegheny County either retained or sold to GLS and who were billed by Allegheny County or GLS for attorneys' fees, interest, and certain other fees and who sustained economic damages on and after August 14, 2003. The putative class allegations are that Allegheny County, GLS, and the Company violated the class's constitutional due process rights in connection with delinquent tax collection efforts. There are also allegations that amounts recovered from the class by GLS and /or Allegheny County are an unconstitutional taking of private property. The claims against the Company are solely based upon its ownership of GLS. The complaint requests that the Court order GLS to account for amounts alleged to have been collected in violation of the putative class members' rights and create a constructive trust for the return of such amounts to members of the purported class. On June 30, 2014, the Court dismissed with prejudice the plaintiffs’ complaint in its entirety. The plaintiffs have appealed.

ITEM 4.    MINE SAFETY DISCLOSURES

The sources of this information are Bloomberg, SNL Financial, and Standard & Poor’s, which management believes to be reliable sources. The historical information set forth above is not necessarily indicative of future performance. Accordingly, we do not make or endorse any predictions as to future share performance.

In December 2014, the Board of Directors authorized the Company 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. This new repurchase authorization replaces the Company's prior share repurchase program which was to expire on December 31, 2014. The Company did not repurchase any shares during the three months ended December 31, 2014.

ITEM 6.    SELECTED FINANCIAL DATA

Our selected financial data presented below is derived from our audited financial statements and should be read in conjunction with our consolidated financial statements and the accompanying notes included under Item 8 of this Annual Report on Form 10-K.

Non-GAAP Financial Measures

In addition to our operating results presented in accordance with GAAP, the information presented below and within Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Annual Report on Form 10-K contains the following non-GAAP financial measures: core net operating income to common shareholders (including per common share), effective borrowing costs and rates, adjusted net interest income, adjusted net interest spread, and adjusted return on average common equity. Management uses these non-GAAP financial measures in its internal analysis of results and operating performance and believes these measures may be important to investors and present useful information about the Company's performance. Schedules reconciling these non-GAAP financial measures to GAAP financial measures are provided below.

Management believes these non-GAAP financial measures are useful because they provide investors greater transparency to the information we use in our financial and operational decision-making processes. Management also believes the presentation of these measures, when analyzed in conjunction with the our GAAP operating results, allows investors to more effectively evaluate and compare our performance to that of our peers. 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 in our consolidated statements of comprehensive income (loss). In addition, because not all companies use identical calculations, our presentation of core net operating income, effective borrowing costs and rates, adjusted net interest income, adjusted net interest spread, and adjusted return on average common equity may not be comparable to other similarly-titled measures of other companies.

Highlights of the 2014 Fiscal Year and Outlook for 2015

We believe we were successful in meeting the challenges presented during 2014 to the mortgage REIT industry from an increasingly complex global macroeconomic environment. While we reduced the assets on our balance sheet and lowered our leverage and spread risk, we generated a total economic return of 15.3% for 2014, which consisted of $1.00 in common dividends plus a $0.33 increase in book value per common share divided by book value per common share of $8.69 at December 31, 2013. The increase in book value was primarily driven by the increase in fair value of our investments as a result of asset credit spread tightening. We believe our balance sheet as of December 31, 2014 reflects a stronger liquidity and capital profile versus December 31, 2013. Entering 2015 with a stronger balance sheet is important to us as we anticipate the market in 2015 will likely hold surprises similar to 2014, given the potential for Federal Reserve action, the low level of absolute rates, the flatter yield curve, and the tighter spread environment.

Despite some fluctuations during 2014, yields available on RMBS and CMBS in the market place generally trended lower during 2014, as market valuations for such bonds generally trended upward in 2014. We believe valuations continue to be supported by market technicals, such as US central bank and global central bank policies which have contributed to excess global liquidity and complacency around risk. We delevered our balance sheet throughout the year by selling investments which we believed were at a higher risk for spread widening and by not fully reinvesting principal payments received on our investments. We have continued to maintain our duration exposure within our guidelines of 0.5-1.5 years, predominantly on the short-end of the curve. We made minimal changes to our hedging portfolio during the fourth quarter of 2014, but our hedging portfolio as of December 31, 2014 has changed significantly since December 31, 2013. We had a lower weighted average net fixed-pay rate and therefore lower net periodic interest costs from derivative instruments. We have continued to extend the maturities of our repurchase agreements to protect us from increased financing costs due to either FOMC action or from higher regulatory costs on our lenders.

The following table provides quarterly information on weighted average effective yields by type of MBS investment as well as other information:

Trends and Recent Market Impacts

There are certain conditions and prospective trends in the marketplace that have impacted our financial condition and results of operations and which may continue to impact us in the future. Conditions and trends that had significant developments during 2014 and that may impact us in 2015 are discussed below.

Federal Reserve Monetary Policy

The FOMC has held the targeted federal funds rate in a range of 0.00% - 0.25% since the end of 2008. The FOMC has indicated that it will assess progress towards its objectives of maximum employment and 2% inflation in determining how long to maintain the current target range. The FOMC has also indicated that it believes that it can be patient in beginning to normalize the stance of monetary policy, although the pace of normalization will depend on the speed of progress toward its objectives. Recent FOMC releases seem to indicate that the FOMC may begin monetary policy normalization in mid-2015. Given the uneven economic performance in the U.S., the lack of consistent global economic growth, and current and developing geopolitical risks, it is possible that the FOMC delays policy normalization or perhaps only modestly increases the targeted rate by 0.25% or 0.50% while it evaluates the impact of tighter credit on the U.S. economy.

The FOMC also continues to reinvest principal payments received on fixed-rate Agency MBS purchased under its now-ended asset purchase programs, collectively known as "QE3". At its peak in 2014, the FOMC was purchasing $85 billion per month in securities. During the fourth quarter of this year, Agency MBS net supply turned positive for the first time in several quarters, a trend which is likely to continue. This trend of positive net supply could negatively impact prices of fixed-rate Agency MBS and may, by extension, impact prices of certain Agency hybrid ARMs as well.

Asset Credit Spreads

Asset credit spreads are defined as the difference between the yields on securities with credit, prepayment or other risks and yields on benchmark securities without these risks (typically Treasuries or swaps), and that reflects the relative riskiness of owning the securities versus the benchmark. Changes in asset credit spreads result from changes in the perceived riskiness of an investment versus its benchmark. Asset credit spreads tightened dramatically in 2014 due in part to Federal Reserve policy, supply and demand imbalances leading to increased competition for assets, and global market liquidity from central bank activities. Asset credit spreads widened modestly in the fourth quarter of 2014 as interest rates rallied and markets generally reduced risk. During the fourth quarter of 2014,we continued to sell assets at most risk to spread widening. We continue to believe that global events

32

will lead to periods of spread volatility in 2015. In general, central bank policy and excess global liquidity have contributed to very low interest rates and a lower volatility environment, and investors in fixed income securities have bid asset prices up as a result as they pursue asset yields. The tight credit spread environment is one of the primary reasons that the Company sold certain CMBS and CMBS IO assets during the second half of 2014.

Regulatory Uncertainty and Reform

Since the financial crisis erupted in 2007, regulators of financial institutions such as the Federal Reserve, the Federal Deposit Insurance Corporation, and the Office of the Comptroller of the Currency have adopted regulatory requirements designed to enhance and maintain financial stability. Financial institutions, particularly larger ones, are now generally subject to higher capital requirements and have reduced their reliance on lower cost, short-term funding sources. Broker-dealer subsidiaries of financial institutions are our primary counterparties for repurchase agreement borrowings. In addition, certain regulations for money market funds have been instituted to address the risk of potential investor runs. Money market funds are an important source of liquidity for the repurchase agreement market. These new financial regulations will be effective beginning in 2015 and through 2018, although many institutions have begun initiatives to comply at a more rapid pace. We have been considering the potential impact of these new regulations on our counterparties and have been managing our financings in an effort to minimize the potential for our borrowing costs to increase. Because we expect the new regulations may lead toward increasing our borrowing costs on repurchase agreements, we are evaluating alternative sources of funding including sources other than broker-dealer subsidiaries of large financial institutions.

GSE Reform

Policy makers in Washington DC continue to debate the future of Fannie Mae and Freddie Mac's participation in the U.S. mortgage market. Several bills have been introduced in the U.S. Senate and the U.S. House of Representatives regarding the reform and/or dissolution of the GSEs. GSE reform has been a very slow process given the continued softness in the housing market and the subdued pace of overall economic growth. The Federal Housing Finance Agency ("FHFA") has offered details on a single MBS security platform that would combine elements of Fannie Mae's and Freddie Mac's current MBS features, which has a goal of eliminating pricing discrepancies in the two entities' securities and to increase liquidity to benefit the housing market. We expect that all of these factors will continue to influence the pace of GSE reform, but we do not expect any meaningful developments in the near term. For further discussion of the uncertainties and risks related to GSE reform, please refer to "Risk Factors" contained within Part I, Item 1A.

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.

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. The following discussion provides information on 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.

Fair Value Measurements. As defined in Accounting Standards Codification ("ASC") Topic 820, the fair value of a financial instrument is the exchange price in an orderly transaction between market participants to sell an asset or transfer a liability in the market in which the reporting entity would transact for the asset or liability, that is, the principal or most advantageous market for the asset or liability. The transaction to sell the asset or transfer the liability is a hypothetical transaction at the measurement date, considered from the perspective of a market participant that holds the asset or liability. ASC Topic 820 provides a consistent definition of fair value which focuses on exit price and prioritizes, within a measurement of fair value, the use of

33

market-based inputs over entity-specific inputs. In addition, ASC Topic 820 provides a framework for measuring fair value and establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date.

Our Agency MBS, as well a majority of our 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 pricing services and dealer quotes. Pricing services and dealers will have access to observable market information through their trading desks. We typically receive a total of three to six prices from pricing services and brokers for each of our securities; prices obtained from brokers are not binding on either the broker or us. Management does not adjust the prices received, but, for securities on which we receive five or more prices, the high and low prices are excluded from the calculation of the average price. In addition, management reviews the prices received for each security by comparing those prices to actual purchase and sale transactions, our internally modeled prices that are calculated based on observable market rates and credit spreads, and the prices that our borrowing counterparties use in financing the our securities. For any security for which significant variations in price exist (from other external prices received or from our internal price), management may exclude such prices from the calculation of the average price. The decision to exclude any price from use in the calculation of the fair values used in our consolidated financial statements is reviewed and approved by management independent of the pricing process. The average of the remaining prices received is used for the fair values included in our consolidated financial statements. If the price of a security is obtained from quoted prices for similar instruments or model-derived valuations whose inputs are observable, the security is classified as a level 2 security. If the inputs are unobservable, the security would be classified as a level 3 security.

As of December 31, 2014, less than 8% of our non-Agency MBS (and less than 2% of our total MBS) are comprised of securities for which there are not substantially similar securities that trade frequently, and therefore, estimates of fair value for those level 3 securities are based primarily on management's judgment. Management determines the fair value of those 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. Generally, level 3 assets are most sensitive to the default rate and severity assumptions. Significant changes in any of these inputs in isolation would result in a significantly different fair value measurement, and accordingly, there is no assurance that our estimates of fair value are indicative of the amounts that would be realized on the ultimate sale or exchange of these assets.

Amortization of Investment Premiums. We amortize premiums and accrete discounts associated with the purchase of our MBS into interest income over the projected lives of our securities, including contractual payments and estimated prepayments, using the effective yield method. Estimates and judgments related to future levels of prepayments are critical to this determination, and they are difficult for management to predict. With respect to both RMBS and CMBS, mortgage prepayment expectations can change based on how changes in current and projected interest rates impact a borrower's likelihood of refinancing as well as other factors, including but not limited to real estate prices, borrowers' credit quality, changes in the stringency of loan underwriting practices, and lending industry capacity constraints. With respect to RMBS, modifications to existing programs such as HARP, or the implementation of new programs can have a significant impact on the rate of prepayments. Further, GSE buyouts of loans in imminent risk of default, loans that have been modified, or loans that have defaulted will generally be reflected as prepayments on our securities and increase the uncertainty around management's estimates. We utilize a third party service to assist in estimating prepayment rates on all MBS. We review these estimates monthly and compare the results to any available market consensus prepayment speeds. We also consider historical prepayment rates and current market conditions to assess the reasonableness of the prepayment rates estimated by the third party service. Actual and anticipated prepayment experience is reviewed monthly and effective yields are adjusted for differences between the previously estimated future prepayments and the amounts actually received as well as changes in estimated future prepayments.

Other-than-Temporary Impairments. When the fair value of an available-for-sale security is less than its amortized cost as of the reporting date, the security is considered impaired. We assess our securities for impairment on at least a quarterly basis and determine if the impairments are either temporary or "other-than-temporary" in accordance with ASC Topic 320-10. Accounting literature does not define what it considers an other-than-temporary impairment ("OTTI") to be; however, it does state that an OTTI does not mean permanent impairment. The literature does provide some examples of factors which may be indicative of an OTTI, such as: (a) the length of time and extent to which market value has been less than cost; (b) the financial condition and near-

34

term prospects of the issuer; and (c) the intent and ability of the holder to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value.

We assess our ability to hold any Agency MBS or non-Agency MBS with an unrealized loss until the recovery in its value. Our ability to hold any such MBS is based on the amount of the unrealized loss and significance of the related investment as well as our current leverage and anticipated liquidity. Although Fannie Mae and Freddie Mac are not explicitly backed by the full faith and credit of the United States, given their guarantee and commitments for support received from the Treasury as well as the credit quality inherent in Agency MBS, we do not typically consider any of the unrealized losses on our Agency MBS to be credit-related. For our non-Agency MBS, we review the credit ratings of these MBS and the seasoning of the mortgage loans collateralizing these securities as well as the estimated future cash flows, which include any projected losses, in order to evaluate whether we believe any portion of the unrealized loss at the reporting date is related to credit losses.

The determination as to whether an OTTI exists as well as its amount is subjective, as such determinations are based not only on factual information available at the time of assessment but also on management’s estimates of future performance and cash flow projections. As a result, the timing and amount of any OTTI may constitute a material estimate that is susceptible to significant change. Our expectations with respect to our securities in an unrealized loss position may change over time, given, among other things, the dynamic nature of markets and other variables. For example, although we believe that the conservatorship of Fannie Mae and Freddie Mac has further strengthened their creditworthiness, there can be no assurance that these actions will be adequate for their needs. Accordingly, if these government actions are inadequate and the GSEs continue to suffer losses or cease to exist, our view of the credit worthiness of our Agency MBS could materially change, which may affect our assessment of OTTI for Agency MBS in future periods. Future sales or changes in our expectations with respect to Agency or non-Agency securities in an unrealized loss position could result in us recognizing other-than-temporary impairment charges or realizing losses on sales of MBS in the future.

FINANCIAL CONDITION

The majority of our MBS as of December 31, 2014 continue to be Agency investments, principally RMBS. During 2014, we shifted our investment mix into more Agency and non-Agency CMBS IO. We sold lower yielding Agency RMBS and used the sale proceeds and principal repayments on our MBS to purchase higher yielding CMBS IO securities. These securities generally have less prepayment risk and therefore more predictable cash flows and yield profiles than Agency RMBS. During the latter half of 2014, we also sold certain non-Agency CMBS investments in order to reduce our portfolio spread risk and to monetize gains from increased market values.

The following tables present our investment allocations based on amortized cost as of the periods indicated:

($ in thousands)	December 31, 2014			December 31, 2013

RMBS

Our RMBS are collateralized substantially by ARMs and hybrid ARMs. Activity related to our RMBS for the year ended December 31, 2014 is as follows:

($ in thousands)	Agency RMBS			Non-Agency RMBS			Total
Balance as of December 31, 2013	$	2,692,150		13,765			$	2,705,915

Balance as of December 31, 2014	$	2,186,700		$	22,448		$	2,209,148

Our investment in Agency RMBS as of December 31, 2014 has decreased over the past year as principal payments and sales have outpaced purchases. Our sales of Agency RMBS during 2014 have consisted of certain lower yielding Agency ARMs that were at or near their initial interest rate reset periods. During 2014, we also purchased a modest amount of non-Agency RMBS at or near par value.

As of December 31, 2014, 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 periods indicated:

	December 31, 2014						December 31, 2013
($ in thousands)	Par Value		Reset Margin		WAC		Par Value		Reset Margin		WAC
0-12 MTR	$	486,638	1.77	%	2.75	%	$	575,763	1.79	%	2.97	%

Total	$	2,086,807			3.09	%	$	2,591,568			3.22	%

The rate at which we amortize the premiums we pay for our investments is impacted by the current and forecasted constant prepayment rate ("CPR"). The following table provides the CPRs on our Agency RMBS for the periods indicated:

	Three Months Ended
	December 31, 2014		September 30, 2014		June 30, 2014		March 31, 2014		December 31, 2013
Agency RMBS	12.5	%	15.3	%	14.1	%	12.7	%	14.3	%

We experienced relatively stable prepayments during 2014 despite the generally lower interest rate environment.We believe this stability is due to constrained lending conditions in the single family mortgage market overall during the past year as well as due to the seasoning of our RMBS.

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 year ended December 31, 2014 is as follows:

($ in thousands)	Agency CMBS			Non-Agency CMBS			Total
Balance as of December 31, 2013	$	331,501		$	369,281		$	700,782
Purchases	21,158			102,419			123,577
Principal payments	(16,160		)	(32,874		)	(49,034		)

Balance as of December 31, 2014	$	335,197		$	208,038		$	543,235

During 2014, we sold a substantial portion of our non-Agency CMBS in order to reduce our exposure to the risk of credit spread widening on those assets. We recognized gains on those sales because of significant price appreciation that resulted from the rally in interest rates and the tightening of credit spreads during the year. Although issued by Freddie Mac, these securities, which we sometimes refer to as "Agency credit securities", are classified by us as non-Agency CMBS because they do not have a guarantee of principal. We partially replaced these investments with purchases of higher credit quality CMBS and CMBS IO. The following table shows purchase price and related net discount on purchases of our non-Agency CMBS during the year ended December 31, 2014 by credit rating at the time of purchase:

	Year Ended

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). Most of our CMBS IO investments are rated 'AAA' by at least one of the nationally recognized statistical ratings organizations.

Activity related to our CMBS IO for the year ended December 31, 2014 is as follows:

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

The underlying notional balances of our Agency and non-Agency CMBS IO portfolios increased to $10.5 billion and $7.9 billion, respectively, as of December 31, 2014 from $10.2 billion and $4.3 billion, respectively, as of December 31, 2013. While we made significant purchases of both Agency and non-Agency CMBS IO during the year, we also sold certain Agency CMBS IO to monetize gains from their significant price appreciation and to reduce our exposure to prepayment risk.

The following table presents the notional value, amortized cost, and weighted average months to estimated maturity of our CMBS IO investments as of December 31, 2014 by year of origination:

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 December 31, 2014, the weighted average notional amount of interest rate derivatives that will be effective for future periods are shown in the following table:

Repurchase Agreements

Our repurchase agreement borrowings have decreased $567.6 million from December 31, 2013 to December 31, 2014 because we have slowed our reinvestment of principal payments and sale proceeds received on our MBS. In addition, the majority of our purchases during the past twelve months have been for non-Agency investments for which we typically borrow a lower percentage of the asset's value. The following tables present the leverage against the amortized cost and fair value of our non-Agency CMBS and CMBS IO investments by credit rating of the collateral pledged as of December 31, 2014 and December 31, 2013:

Please refer to Note 5 of the Notes to the Consolidated Financial Statements contained within this Annual Report on Form 10-K as well as "Interest Expense, Annualized Cost of Funds, and Effective Borrowings Costs" within "Results of Operations" and “Liquidity and Capital Resources” contained within this Item 7 for additional information relating to our repurchase agreements.

RESULTS OF OPERATIONS

In addition to our operating results presented in accordance with GAAP, our results of operations discussed below contain certain non-GAAP financial measures including core net operating income, adjusted net interest income, and effective borrowing cost and certain financial metrics derived from non-GAAP information, such as adjusted net interest spread and effective borrowing rate. Schedules reconciling these non-GAAP financial measures to GAAP financial measures are provided in Item 6 within Part II of this Annual Report on From 10-K. As discussed in more detail below, management believes these non-GAAP financial measures are useful because they provide investors greater transparency to the information we use in our financial and operational decision-making processes. Management also believes the presentation of these measures, when analyzed in conjunction with the our GAAP operating results, allows investors to more effectively evaluate and compare our performance to that of our peers. However, because such measures are incomplete measures of our financial performance and involve differences from results computed in accordance with GAAP, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, our GAAP results as reported in our consolidated statements of comprehensive income (loss). In addition, because not all companies use identical calculations, our presentation of such non-GAAP measures may not be comparable to other similarly-titled measures of other companies.

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 tables present 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 the increase (decrease) in 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.

(2) Amount includes other interest income amounts of $3.9 million, $3,2 million, and $1.6 million for the years ended December 31, 2014, 2013, and 2012, respectively, related to prepayment penalty income and other yield maintenance items. The majority of the other interest income amounts for the years ended December 31, 2014 and December 31, 2013 related to CMBS IO and the majority of the other interest income amount for the year ended December 31, 2012 related to CMBS.

Our interest income from MBS for the year ended December 31, 2014 decreased compared to the year ended December 31, 2013 due to a decrease in the average balance of our MBS portfolio and a decrease in the weighted average effective yield earned on our MBS portfolio. The balance of our investment portfolio declined throughout the year as the proceeds we received from sales of and principal repayments on our MBS were used to pay down our repurchase agreements borrowings rather than fully reinvesting into new assets. Our purchases of new assets declined during 2014 as there were fewer opportunities to add investments with acceptable risk and return profiles. Average yields on our MBS were lower as purchases across the portfolio

42

were made at lower yields, in particular CMBS IO, and we experienced downward resets in interest rates on our variable-rate securities during 2014.    

Our interest income from MBS for the year ended December 31, 2013 increased compared to the year ended December 31, 2012 due to an increase in the average balance of our MBS portfolio, and in particular an increase in our Agency and non-Agency CMBS IO portfolios. The impact of a larger average balance was partially offset by lower weighted average effective yields earned on our investments due to lower weighted average coupons (primarily on MBS purchased during 2013) and higher premium amortization during the year ended December 31, 2013.

The following table presents information regarding net premium amortization by collateral type for the periods indicated:

	Year Ended December 31,
	2014				2013				2012
($ in thousands)	Net Premium Amortization		Average Balance of Unamortized Premium, Net		Net Premium Amortization		Average Balance of Unamortized Premium, Net		Net Premium Amortization		Average Balance of Unamortized Premium, Net
RMBS	$	28,533	$	131,899	$	33,116	$	156,882	$	32,391	$	118,997
CMBS	3,874		4,392		3,709		5,213		3,613		5,929

	$	139,240	$	802,579	$	128,881	$	801,543	$	91,479	$	524,629

Net premium amortization increased for the year ended December 31, 2014 compared to the same period in 2013 because of the shift in our portfolio toward CMBS IO which typically have higher premium balances than RMBS. Our average balance of net unamortized premium did not increase significantly for the year ended December 31, 2014 compared to the same period in 2013 as we reduced our investment portfolio as noted in "Financial Condition" discussed above. Similarly, our average balance of net unamortized premium during the year ended December 31, 2013 was more heavily weighted toward higher priced CMBS and CMBS IO than in 2012. Unlike 2014, however, we also experienced significant growth in our RMBS premiums for the year ended December 31, 2013 which further contributed to the increase in net premium amortization compared to the year ended December 31, 2012.

Interest Expense, Annualized Cost of Funds, and Effective Borrowing Costs

(2) Rates shown are based on annualized interest expense amounts divided by average balance of borrowings. Recalculation of annualized cost of funds using total interest expense shown in the table may not be possible because certain expense items 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 the average balance of repurchase agreement borrowings and average borrowing rates on the decrease in interest expense for the comparative periods presented:

	Year Ended									Year Ended
	December 31, 2014 vs. December 31, 2013									December 31, 2013 vs. December 31, 2012
				Due to Change in								Due to Change in
($ in thousands)	Decrease in Interest Expense			Average Balance			Average Borrowing Rate			Decrease in Interest Expense		Average Balance		Average Borrowing Rate
Repurchase agreements	$	(5,080	)	$	(2,798	)	$	(2,282	)	$	4,772	$	4,719	$	53

Interest expense from repurchase agreements borrowings for 2014 was lower than 2013 as a result of the lower average balance outstanding as well as a lower borrowing rate overall. Average balances of repurchase agreement borrowings were lower in 2014 compared to 2013 given our smaller investment portfolio and the overall shift in our portfolio mix to lower leveraged CMBS IO investments. Repurchase agreement borrowing rates declined throughout 2014 as funding markets adjusted their expectations of when the FOMC would begin to raise rates and as excess liquidity in the financing markets increased competition among our repurchase agreement counterparties. During the second half of 2014, we began to extend the maturities of our repurchase agreement financings to take advantage of lower rates. Our weighted average original term to maturity for our repurchase agreements as of December 31, 2014 was 144 days compared to 114 days as of December 31, 2013.

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

Average balance of repurchase agreements	$	3,335,786				$	3,773,744				$	3,033,634

(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 on which the Company discontinued cash flow hedge accounting.

(2) Rates shown are based on annualized interest expense amounts divided by average balance of borrowings. Recalculation of annualized cost of funds and effective borrowing rates using interest expense shown in the table may not be possible because certain expense items use a 360-day year for the calculation while others use actual number of days in the year. 

Effective borrowing costs were $15.4 million lower for the year ended December 31, 2014 versus the same period in 2013, of which $9.5 million resulted from a decrease in the weighted average notional balance outstanding for our interest rate

44

swaps of approximately $793.8 million as well as a decrease of approximately 9 basis point in the weighted average net pay rate. As part of our overall interest rate risk management process, we entered into receive-fixed interest rate swaps to offset pay-fixed interest rate swap positions we held at certain points in time. Using interest rate swaps in offsetting positions provides us the flexibility to better manage exposure to specific points on the yield curve. We expect to continue to use both pay-fixed and receive-fixed interest rate swaps to manage our overall hedge position. Please refer to "Derivative Assets and Liabilities" contained in "Financial Condition" as well as "Loss on Derivative Instruments, Net" contained with these "Results of Operations" for further information on our derivative instruments. The remainder of the decrease in our effective borrowing costs for the year ended December 31, 2014 versus the same period in 2013 resulted from the lower average balances outstanding for our repurchase agreement and non-recourse collateralized financings as well as our overall lower average borrowing rates for our repurchase agreements.

Effective borrowing costs increased $7.0 million for the year ended December 31, 2013 versus the same period in 2012, of which $4.8 million resulted primarily from an increased average balance of repurchase agreement borrowings used to fund our investment purchases and $2.6 million resulted from increased net periodic interest costs due to additional derivative instruments we used to hedge exposure to increases in interest rates during 2013. These increases were offset by a decrease of $0.4 million in our interest expense from non-recourse collateralized financing. In spite of the increase in our effective borrowing costs, our effective borrowing rate decreased for the year ended December 31, 2013 versus for the year ended December 31, 2012 because our non-recourse collateralized financing, which has a higher rate of financing, comprised a smaller portion of our average balance of total financings for the year ended December 31, 2013 compared to the year ended December 31, 2012. In addition, our effective borrowing rate decreased because, although our total net periodic interest costs increased $2.6 million for 2013 versus 2012, these costs decreased as a percentage of our average repurchase agreement borrowings for the year ended December 31, 2013 compared to the year ended December 31, 2012. Average borrowing rate from our repurchase agreements was stable at 0.63% for the year ended December 31, 2013 compared to the year ended December 31, 2012.

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.

(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 the Company's discontinuation of cash flow hedge accounting.

(2) Amount equals the net interest cost related to interest rate derivatives during the period which is recorded in "loss on derivative instruments, net" and not already included in "interest expense" in accordance with GAAP.

(3) 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.

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

Our net interest income and adjusted net interest income decreased for the year ended December 31, 2014 compared to the same period in 2013 due to smaller average interest earning asset balances, lower coupons earned on our investments, and higher premium amortization resulting from the shift in our portfolio toward CMBS IO as discussed above under "Interest Income and Asset Yields". The impact of smaller average interest earning asset balances and lower coupons was partially offset by lower overall annualized cost of funds and lower effective borrowing costs as further discussed above under "Interest Expense, Annualized Cost of Funds, and Effective Borrowing Costs" and below under "Loss on Derivative Instruments, Net". Conversely, our net interest spread increased 5 basis points for the year ended December 31, 2014 compared to the same period in 2013 as a result of declining repurchase agreement costs which more than offset the decline in weighted average effective yields on our investments. Adjusted net interest spread increased 9 basis points for the year ended December 31, 2014 compared to the same period in 2013 as a result of lower net periodic interest costs.

The increase in net interest income and adjusted net interest income for the year ended December 31, 2013 compared to the same period in 2012 was primarily the result of growth in our investment portfolio during 2013. Conversely, our net interest spread and adjusted net interest spread decreased for the year ended December 31, 2013 compared to the same period in 2012. This decrease was driven primarily by declining weighted average effective yields on our overall investment portfolio as we were adding lower yielding purchases at higher premiums and our existing variable-rate RMBS were reaching their reset periods in a lower interest rate environment.

Loss on Derivative Instruments, Net

The following table provides information on the components of our "loss on derivative instruments, net" for the periods indicated:

	Year Ended (1)

(1) This table does not include detail for loss on derivative instruments, net for the year ended December 31, 2012 because the results are not directly comparable to the other periods presented. Because the majority of our interest rate swaps outstanding during the year ended December 31, 2012 were accounted for cash flow hedges, the majority of the change in their fair value during that period were recorded in "other comprehensive income". Loss on derivative instruments, net for the year ended December 31, 2012 consisted of $0.6 million net periodic interest costs and $0.3 million change in fair value from interest rate swap-payers that were not designated as cash flow hedges for accounting purposes. We did not have Eurodollar futures or interest rate swap-receivers outstanding during the year ended December 31, 2012.

(2) During the years ended December 31, 2013 and December 31, 2012, we recorded an additional $8.8 million and $14.4 million, respectively, within "interest expense" for net periodic interest costs from interest rate swap-payers while they were designated as cash flow hedges for accounting purposes. We discontinued cash flow hedge accounting for all of our derivative instruments as of June 30, 2013.

Loss on derivative instruments, net for the year ended December 31, 2014 increased by $43.3 million compared to the year ended December 31, 2013, principally as a result of the shifts in the yield curve during 2014. For example, the two-year swap rate increased by 0.41% during the year but the ten-year swap rate declined during the year by 0.83%. Our derivatives hedge different points on the yield curve, but, in general, declines in longer-term swap rates will result in a higher amount of losses on our derivative position. These losses were offset by increases in the fair value of our investments which are included in other comprehensive income. The notional amount of derivative instruments outstanding from period to period fluctuate based on the composition of our investment portfolio and the current interest rate environment as well as management's expectation of future interest rates.

Sales of our investments occur in the ordinary course of business as we manage our risk profile and as we allocate capital to preferred investment opportunities. Agency RMBS sold during the year ended December 31, 2014 and December 31, 2013 were resetting or close to resetting their interest rates in a lower interest rate environment. These sales of Agency RMBS generated losses because the amount of unamortized premium remaining was higher than the proceeds we received upon sale as a result of their yields being lower than current market yields. During the year ended December 31, 2012, we sold certain Agency RMBS to monetize gains from significant price appreciation experienced during that period and to reduce our exposure to prepayment risk.

During the year ended December 31, 2014, we sold certain Agency CMBS IO and non-Agency CMBS in order to reduce our portfolio exposure to spread and prepayment risk and to monetize gains from their increased market value. Similarly, our sales of MBS investments for the year ended December 31, 2013 increased considerably compared to the year ended December 31, 2012 due to management's decision to reduce portfolio risk given the volatile market environment experienced in 2013.

General and Administrative Expenses

General and administrative expenses were $16.0 million for the year ended December 31, 2014 compared to $13.1 million for the year ended December 31, 2013. Compensation and benefits increased $2.5 million due to increased incentive compensation, an additional executive officer, and increased stock based compensation expense. Incentive compensation paid in cash is recognized as expense in the period earned whereas incentive compensation paid in restricted stock is recognized over its vesting period. Approximately $1.4 million of incentive compensation for executive management for the year ended December 31, 2013 was paid in restricted stock with a vesting period of three years and $0.1 million in cash. For the year ended December 31, 2014, $1.6 million was paid in cash and $1.6 million in restricted stock with a vesting period of three years. Other general and administrative expenses for the year ended December 31, 2014 increased $0.4 million compared to the year ended December 31, 2013 primarily because of increased legal expenses.

For the year ended December 31, 2013, compensation and benefits decreased $0.6 million compared to the year ended December 31, 2012 due to lower bonuses earned as well as an increased amount of bonuses being paid in restricted stock in lieu of cash. Other general and administrative expenses for the year ended December 31, 2013 increased approximately $1.0 million compared to the year ended December 31, 2012 due to increased expenses related to portfolio management and analysis tools.

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, 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 December 31, 2014 were $215.8 million compared to $208.7 million as of December 31, 2013. As of December 31, 2014, our liquid assets consist of unrestricted cash and cash equivalents of $43.9 million and $171.8 million in unencumbered Agency MBS. Unencumbered Agency MBS are considered part of our liquid assets as we may pledge them to lenders and interest rate swap counterparties if we experience a margin call (discussed further below). We do not include unencumbered non-Agency MBS as liquid assets given the uncertainty of their liquidity in times of market stress.

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 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 decreased to 5.1 times shareholders' equity as of December 31, 2014 from 6.2 times as of December 31, 2013. Over the last several quarters we have reduced our leverage due to the tighter credit spread environment and the resulting spread risk on our investments, and also due to the potential for increased regulatory risk and overall market risk as discussed below.

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 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:

48

($ in thousands)	Balance Outstanding As of Quarter End		Average Balance Outstanding For the Quarter Ended		Maximum Balance Outstanding During the Quarter Ended
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
December 31, 2013	3,580,754		3,603,477		3,675,290
September 30, 2013	3,674,850		3,836,249		4,071,773
June 30, 2013	4,071,392		4,042,340		4,255,294
March 31, 2013	3,708,255		3,612,319		3,752,000

We have been lowering our leverage by reducing our repurchase agreement borrowings over the past several quarters due to the potential volatility in asset prices as a result of market uncertainty, a flatter yield curve, and tight spread environment. Our conservative management of our investment portfolio led us to decrease our reinvestment of principal payments and proceeds received from MBS sales into new investments during 2014. In addition, we have been using our repurchase agreement borrowings to purchase assets for which we typically finance a lower percentage of their market value.

Throughout 2014, we managed the maturities of our repurchase agreements based on market conditions. The weighted average original term to maturity for our repurchase agreement borrowings was 144 days as of December 31, 2014 compared to 114 days as of December 31, 2013. 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 event of a counterparty's failure to renew existing repurchase agreements either with favorable terms or at all. As of December 31, 2014, we had repurchase agreement borrowings outstanding with 20 of our 33 available repurchase agreement counterparties at a weighted average borrowing rate of 0.55% compared to 0.61% as of December 31, 2013. 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 minimum weighted average 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:

	December 31, 2014		September 30, 2014		June 30, 2014		March 31, 2014		December 31, 2013
Agency MBS	6.8	%	6.8	%	6.6	%	6.9	%	6.8	%
Non-Agency MBS	16.0	%	16.9	%	18.5	%	19.8	%	20.1	%

49

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 December 31, 2014 and as of December 31, 2013:

	December 31, 2014
($ in thousands)	Amount Outstanding		Equity at Risk
Well Fargo Bank, N.A. and affiliates	$	286,574	$	53,949
JP Morgan Securities, LLC	289,931		48,484
South Street Financial Corporation	608,000		36,483
Bank of America Securities LLC	181,593		15,711
Credit Suisse Securities LLC	103,078		13,258
Remaining counterparties	1,543,934		93,603
	$	3,013,110	$	261,488

	December 31, 2013
($ in thousands)	Amount Outstanding		Equity at Risk
Well Fargo Bank, N.A. and affiliates (1)	$	371,753	$	91,769
JP Morgan Securities, LLC	240,024		39,397
South Street Financial Corporation	601,354		29,331
Credit Suisse Securities LLC	210,861		25,093
Bank of America Securities LLC	226,768		23,886
Remaining counterparties	1,930,237		102,797
	$	3,580,997	$	312,273

(1) Amount excludes deferred costs related to our committed two-year repurchase facility with Wells Fargo Bank National which had a remaining balance of $0.2 million as of December 31, 2013.

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 December 31, 2014:

($ in thousands)	Amount Outstanding		Market Value of Collateral Pledged
North America	$	1,957,795	$	2,148,583
Asia	602,943		635,852
Europe	452,372		490,162
	$	3,013,110	$	3,274,597

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.

50

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 value 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 December 31, 2014, we had Agency MBS with a fair value of $2.4 million and cash of $42.3 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). As of December 31, 2014, we had an estimated NOL carryfoward of $120.0 million. Due to an ownership shift in 2012, the use of the NOL is limited to $13.5 million per year plus any amounts unused from prior years.

Contractual Obligations

The following table summarizes our contractual obligations by payment due date as of December 31, 2014:

($ in thousands)	Payments due by period
Contractual Obligations:	Total		< 1 year		1-3 years		3-5 years		> 5 years
Repurchase agreements (1)	$	3,016,418	$	3,016,418	$	—	$	—	$	—
Non-recourse collateralized financing (2)	10,967		2,726		3,898		2,234		2,109
Operating lease obligations	1,028		99		202		208		519
Total	$	3,028,413	$	3,019,243	$	4,100	$	2,442	$	2,628

(1) Includes estimated interest payments calculated using interest rates in effect as of December 31, 2014.

(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.

Off-Balance Sheet Arrangements

As of December 31, 2014, 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, liquidity or capital resources.

ITEM 7A. 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 us 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. 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 shorter maturities or 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 December 31, 2014 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 December 31, 2014, and because we believe it is unlikely that absolute rates will move lower from rates at December 31, 2014, the only declining rate scenario that we present is a downward shift of 25 basis points.

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 December 31, 2014 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.

Parallel Shift in Interest Rates	Percentage change in market value (1)	Percentage change in adjusted net interest income
+100	(0.79)%	(10.28)%
+50	(0.34)%	(4.19)%
-25	0.11%	0.78%

54

(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 December 31, 2014.

Basis point change in  2-year yield	Basis point change in  10-year yield	Percentage change in market value
0	+25	0.04%
+10	+50	0.02%
+10	+75	—%
+25	+75	(0.05)%
+25	+0	(0.07)%
+50	+0	(0.15)%
-10	-50	(0.16)%

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 December 31, 2014:

Lifetime Interest Rate Caps			Interim Interest Rate Caps
	% of Total			% of Total
>7.4% to 10.0%	87.6	%	1.0%	1.0	%
>10.0% to 11.0%	9.0	%	2.0%	17.2	%
>11.0% to 12.1%	3.4	%	5.0%	81.8	%
	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 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-

55

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 December 31, 2014:

Basis Point Change in Market Credit Spreads	Percentage change in market value of investments
+50	(1.6)%
+25	(0.8)%
-25	0.8%
-50	1.7%

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:

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, our default experience on loans in CMBS and CMBS IO has been relatively low.

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, (ie, 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. We sold the majority of our Agency CMBS IO issued by Ginnie Mae during 2014 to reduce exposure to prepayment risk and in part to rotate capital into non-Agency CMBS IO. The following table details the fair value of our CMBS IO portfolio by issuer as of the end of the periods indicated:

($ in thousands)	December 31, 2014		December 31, 2013
Fannie Mae	$	28,765	$	70,288
Freddie Mac	408,698		312,089
Ginnie Mae	1,274		77,950
Non-Agency CMBS IO	325,119		$	151,137
	$	763,856	$	611,464

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).

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 December 31, 2014:

	December 31, 2014
($ in thousands)	CMBS		CMBS IO		RMBS		Total		Percentage
AAA	$	73,553	$	321,154	$	—	$	394,707	71.0	%
AA	65,937		1,057		—		66,994		12.1	%
A	30,828		—		—		30,828		5.5	%
Below A or not rated	37,720		2,908		22,448		63,076		11.4	%
	$	208,038	$	325,119	$	22,448	$	555,605	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 Item 7 of this Annual Report on Form 10-K.

ITEM 9A. 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 December 31, 2014 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

58

There were no changes in our internal control over financial reporting during the three months ended December 31, 2014 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Because of inherent limitations, a system of internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate due to change in conditions, or that the degree of compliance with policies or procedures may deteriorate.

Our management evaluated, with the participation of our principal executive officer and principal financial officer, the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) (2013) in “Internal Control-Integrated Framework.” Based on that evaluation, our principal executive officer and principal financial officer concluded that our internal control over financial reporting was effective as of the end of the period covered by this report.

The Company’s internal control over financial reporting as of December 31, 2014 has been audited by BDO USA, LLP, the independent registered public accounting firm that also audited the Company’s consolidated financial statements included in this Annual Report on Form 10-K. The attestation report of BDO USA, LLP on the effectiveness of the Company’s internal control over financial reporting appears on page F-4 herein.

ITEM 9B. OTHER INFORMATION

During 2014 our Compensation Committee (the “Committee”) worked with its compensation consultant and our management to determine appropriate compensation levels for our executive officers and design a new compensation program framework. As part of this new framework, the Committee and Board had planned to adopt a new incentive compensation plan for our executive officers for 2014. At a meeting on January 30, 2015, in light of the fact that the new incentive compensation plan has not yet been finalized, the Committee, in the exercise of its discretion, made the adjustments described below to the operation of the Company’s Performance Bonus Program (the “Bonus Program”) with respect to determining annual bonus awards for the named executive officers for 2014 performance. Many of these adjustments reflect changes the Committee and Board have been considering incorporating into the new incentive compensation plan.

• In light of his January 1, 2014 transition from Chief Executive Officer to Executive Chairman, the Committee determined that Mr. Akin would not participate in the Bonus Program for 2014 and would instead be eligible for a discretionary bonus as determined by the Committee.

• In light of the fact that the Company did not engage in any capital raising during 2014, the Committee adjusted the percentages for the three components of the Bonus Program for 2014 from: (i) 25% based on return earned on average common equity (“ROAE”), 25% based on qualitative performance objectives determined by the Committee and adjusted for individual performance, and 50% based on capital raising activities for the Company during the year; to (ii) 40% based on ROAE, 40% based on qualitative performance objectives determined by the Committee and adjusted for individual performance, and 20% based on total economic return for 2014, calculated as the change in the Company’s GAAP book value per basic common share plus dividends declared by the Company during the year, divided by the Company’s GAAP book value per basic common share at the beginning of the year.

• Consistent with its belief that it is important for a portion of management’s bonus compensation to be paid in restricted shares of the Company’s common stock, the Committee determined that bonuses awarded under the Bonus Program would be paid 50% in cash and 50% in shares of restricted stock that vest over three years.

• Both the cash and stock portions of the bonuses to be paid under the Bonus Program for 2014 would be paid on February 25, 2015.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

Dynex Capital, Inc.

Glen Allen, Virginia

We have audited the accompanying consolidated balance sheets of Dynex Capital, Inc. (Dynex) as of December 31, 2014 and 2013 and the related consolidated statements of comprehensive income (loss), shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2014. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Dynex at December 31, 2014 and 2013, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Dynex's internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated March 12, 2015 expressed an unqualified opinion.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

Dynex Capital, Inc.

Glen Allen, Virginia

We have audited Dynex Capital, Inc.’s (Dynex) internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control - Integrated Framework(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Dynex’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A, Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Dynex maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Dynex as of December 31, 2014 and 2013, and the related consolidated statements of comprehensive income (loss), shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2014 and our report dated March 12, 2015 expressed an unqualified opinion thereon.

NOTES TO THE 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 consolidated financial statements of Dynex Capital, Inc. and its qualified real estate investment trust ("REIT") subsidiaries and its taxable REIT subsidiary (together, "Dynex" or the "Company") have been prepared in accordance with the generally accepted accounting principles in the United States ("GAAP") and the instructions to the Annual Report on Form 10-K and Article 3 of Regulation S-X promulgated by the Securities and Exchange Commission (the "SEC").

Reclassifications

Certain items in the prior periods' consolidated financial statements have been reclassified to conform to the current year’s presentation. The Company's consolidated balance sheet as of December 31, 2013 now presents its "securitized mortgage loans, net" and "other investments, net" together as "mortgage loans held for investment, net ". In addition, the Company has combined the presentation of its consolidated statements of income and its consolidated statements of other comprehensive income together as one financial statement which is now titled "consolidated statements of comprehensive income". The Company's "interest income - securitized mortgage loans" and "interest income-other investments" on its consolidated statements of income for the years ended December 31, 2013 and December 31, 2012 are now presented together as "interest income-mortgage loans held for investment, net" on its consolidated statements of comprehensive income for the years ended December 31, 2013 and December 31, 2012. The Company's "amortization and depreciation" on its consolidated statements of cash flows for the years ended December 31, 2013 and December 31, 2012 are now presented as "amortization of investment premiums, net" and "other amortization and depreciation". These presentation changes have no effect on reported total assets, total liabilities, results of operations, or cash flow activities.

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.

(amounts in thousands except share and per share data)

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 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 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

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

F-10

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

DYNEX CAPITAL, INC.

(amounts in thousands except share and per share data)

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 8 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 3 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

F-11

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

DYNEX CAPITAL, INC.

(amounts in thousands except share and per share data)

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.

Effective June 30, 2013, the Company discontinued cash flow hedge accounting for derivative instruments which had previously been accounted for as cash flow hedges under ASC Topic 815. Activity up to and including June 30, 2013 for those agreements previously designated as cash flow hedges was recorded in accordance with cash flow hedge accounting as prescribed by ASC Topic 815, which states that the effective portion of the hedge relationship on an instrument designated as a cash flow hedge is reported in the current period's other comprehensive income while the ineffective portion is immediately reported as a component of the current period’s net income. The balance remaining in AOCI related to the de-designated cash flow hedges is amortized into the Company's net income as a portion of "interest expense" over the remaining life of the interest rate swap agreements. Subsequent to June 30, 2013, changes in the fair value of the Company's derivative instruments, plus periodic settlements, are recorded in the Company's net income as a portion of "gain (loss) on derivative instruments, net".

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 December 31, 2014, the Company does not have any contingencies for which it believes a probable loss has been incurred.

Recent Accounting Pronouncements

In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures, which changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. The guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement, which has resulted in outcomes referred to as off-balance-sheet accounting. All of the Company's repurchase agreement transactions are accounted for as secured borrowings; therefore the accounting changes required by ASU No. 2014-11 do not impact the Company's consolidated financial statements. ASU No. 2014-11 also requires two additional disclosures about repurchase agreements and other similar transactions. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The Company does not account for any of its repurchase agreement transactions as sales; therefore this new disclosure does not impact the Company's current disclosures. The second

F-12

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(amounts in thousands except share and per share data)

disclosure requires the following disclosures for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings: a disaggregation of the gross obligation by the class of collateral pledged; the remaining contractual tenor of the agreements; and a discussion of the potential risks associated with the agreements and the related collateral pledged, including obligations arising from a decline in the fair value of the collateral pledged and how those risks are managed. The Company already provides these disclosures in its "Notes to the Consolidated Financial Statements" and within "Liquidity and Capital Resources" in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Annual Report on Form 10-K. The amendments provided in ASU No. 2014-11 are effective for public business entities for the first interim or annual period beginning after December 15, 2014. ASU No. 2014-11 will not have a material impact on the Company's consolidated financial statements.

In addition, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company has not issued and does not anticipate issuing any share-based payments with terms that require a performance-based target; therefore this ASU will not have an impact on the Company's consolidated financial statements.

The FASB issued ASU No. 2014-13, Consolidation (Topic 810): Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity, which provides an alternative to Topic 820, Fair Value Measurement, for measuring the financial assets and the financial liabilities of a consolidated collateralized financing entity to eliminate the difference in the fair value of the financial assets of a collateralized financing entity, as determined under GAAP, when they differ from the fair value of its financial liabilities even when the financial liabilities have recourse only to the financial assets. When the measurement alternative is elected, both the financial assets and the financial liabilities of the collateralized financing entity should be measured using the more observable of the fair value of the financial assets or the fair value of the financial liabilities. The amendments clarify that when the measurement alternative is elected, a reporting entity's consolidated net income (loss) should reflect the reporting entity's own economic interests in the collateralized financing entity, including; (1) changes in the fair value of the beneficial interests retained by the reporting entity, and (2) beneficial interests that represent compensation for services. The measurement alternative provided in ASU No. 2014-13 may be applied using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the annual period of adoption. The amendments may also be applied retrospectively to all relevant prior periods beginning with the annual period in which ASU No. 2009-17 was initially adopted. ASU No. 2014-13 is effective for public entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, and early adoption is permitted as of the beginning of an annual period. Management has evaluated ASU No. 2014-13 and has determined that if the Company elects to adopt this measurement alternative in the future for its currently existing consolidated collateralized financing entity, it will not have a material impact on the Company's consolidated financial statements.

The FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, which provides guidance about management's responsibility under GAAP to evaluate whether there is substantial doubt about an organization's ability to continue as a going concern and to provide related footnote disclosures. Specifically, the ASU (1) provides a definition of the term "substantial doubt", (2) requires an evaluation by management every reporting period including interim periods, (3) provides principles for considering the mitigating effect of management's plans, (4) requires certain disclosures when substantial doubt exists regardless of the success of any mitigating plans or actions, (5) requires an express statement and other disclosures when substantial doubt is not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued. The amendments in this ASU are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. Management intends to comply with the requirements set forth in ASU No. 2014-15.

NOTE 2 – NET INCOME PER COMMON SHARE

Because the Company's Series A Cumulative Redeemable Preferred Stock and Series B Cumulative Redeemable 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 per common share. 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 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.

The following table presents the calculation of the numerator and denominator for both basic and diluted net income per common share for the periods indicated:

Net income per common share:
Basic and diluted (1)				$	0.34				$	1.10				$	1.35

(1) For the year ended December 31, 2012, the calculation of diluted net income per common shareexcludes the effect of 15,000 unexercised stock option awards because their inclusion would have been anti-dilutive. The Company did not have any potentially dilutive securities outstanding for the years ended December 31, 2014 or December 31, 2013.

(2) As of December 31, 2013, the Company had Agency CMBS with an amortized cost of $26,920 and fair value of $28,717 which were designated as trading securities and are not included in this table. The Company changed the designation of these Agency CMBS to AFS during the three months ended June 30, 2014. Changes in the fair value of these MBS while they were designated as trading were recognized in net income within "fair value adjustments, net". Changes in the fair value of these MBS, which are now designated as AFS, are recognized in "other comprehensive income". As of December 31, 2014, the Company does not have any MBS designated as trading.

(3) The notional balance for the Agency CMBS IO and non-Agency CMBS IO was $10,160,502 and $4,274,957, respectively, as of December 31, 2013.

The Company received proceeds of $503,918, $357,892, and $125,108 for the sale of MBS during the years ended December 31, 2014, December 31, 2013, and December 31, 2012, respectively. The following table presents the gross realized gains (losses) of those sales included in "gain on sale of investments, net" on the Company's consolidated statements of comprehensive income for the periods indicated:

The following table presents certain information for those Agency MBS in an unrealized loss position as of December 31, 2014 and December 31, 2013:

	December 31, 2014						December 31, 2013
	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	$	322,741	$	(879	)	24	$	1,912,937	$	(43,543	)	150
Non-Agency MBS	111,778		(625		)	24	162,558		(5,435		)	39
Continuous unrealized loss position for 12 months or longer:
Agency MBS	$	1,321,323	$	(21,491	)	113	$	670,402	$	(20,433	)	67
Non-Agency MBS	18,037		(159		)	5	6,310		(155		)	6

Because the principal related to Agency MBS are 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 December 31, 2014 and December 31, 2013 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 December 31, 2014 or December 31, 2013.

NOTE 4 – MORTAGE LOANS HELD FOR INVESTMENT, NET AND RELATED NON-RECOURSE FINANCING

The Company's mortgage loans held for investment, net consist of securitized and unsecuritized mortgage loans originated or purchased by the Company from 1992 through 1998. The following table provides detail by type of collateral as of the periods indicated:

	December 31, 2014			December 31, 2013
Single-family mortgage loans held for investment, amortized cost	$	30,214		$	35,328
Commercial mortgage loans held for investment, amortized cost	9,736			20,352
Allowance for loan losses	(250		)	(257		)
Total mortgage loans held for investment, net	$	39,700		$	55,423

Commercial securitized mortgage loans are evaluated individually for impairment when the debt service coverage ratio on the mortgage loan is less than 1:1 or when the mortgage loan is delinquent. Commercial mortgage loans not evaluated for individual impairment are evaluated for a general allowance. There were no securitized commercial mortgage loans identified as seriously delinquent (60 or more days past due) on the Company's consolidated balance sheets as of December 31, 2014 or as of December 31, 2013.

Single-family mortgage loans are considered homogeneous and are evaluated on a pool basis for a general allowance. The unpaid principal balance of the Company's securitized single-family mortgage loans identified as seriously delinquent as of

F-16

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

DYNEX CAPITAL, INC.

(amounts in thousands except share and per share data)

December 31, 2014 was $2,221 compared to $2,758 as of December 31, 2013. The Company continues to accrue interest on its seriously delinquent securitized single-family mortgage loans because the primary servicer continues to advance the interest and/or principal due on the loan.

The Company considers various factors in determining its specific and general allowance requirements, including whether a loan is delinquent, the Company’s historical experience with similar types of loans, historical cure rates of delinquent loans, and historical and anticipated loss severity of the mortgage loans as they are liquidated. The factors may differ by mortgage loan type (e.g., single-family versus commercial) and collateral type (e.g., multifamily versus office property). The allowance for loan losses is evaluated and adjusted periodically by management based on the actual and estimated timing and amount of probable credit losses, using the above factors, as well as industry loss experience.

The majority of the Company's mortgage loans held for investment, net are securitized mortgage loans, of which $11,902 of principal is pledged as collateral for an outstanding class of the Company's single-family securitization financing bond, which is recorded on the Company's balance sheet as "non-recourse collateralized financing". The interest rate on this bond is based on 1-month LIBOR plus 0.30% and has an estimated life remaining of less than 3 years as of December 31, 2014. The principal balance outstanding as of December 31, 2014 is $10,967 compared to $13,134 as of December 31, 2013.

As of December 31, 2014, shareholders' equity at risk did not exceed 10% for any of the Company's counterparties. The Company had $247,115 of its repurchase agreement balance as of December 31, 2014 outstanding under a two-year repurchase facility with Wells Fargo Bank National Association. Subsequent to December 31, 2014, this facility was amended to increase its aggregate maximum borrowing capacity to $300,000 and to extend the maturation to 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 December 31, 2014 was 1.01%.

As of December 31, 2014, 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 December 31, 2014.

Please see Note 7 for the Company's disclosures related to offsetting assets and liabilities.

NOTE 6 – 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.

December 31, 2014 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. Because of differing market values and maturities at the time of cash flow hedge de-designation, the balance remaining in AOCI is comprised of both unrealized gains and unrealized losses which will not be recognized in net income equally over time. All forecasted transactions associated with interest rate swap agreements previously designated as cash flow hedges are expected to occur. No amounts have been reclassified to net income in any period in connection with forecasted transactions that are no longer considered probable of occurring. 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 $3,460.

The table below describes the components of the reclassification adjustments out of AOCI related to certain interest rate swaps that were formerly designated as cash flow hedges and recognized as a portion of "interest expense" on the Company statements of comprehensive income for the periods indicated:

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 GAAP 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 December 31, 2014.

Please see Note 7 for the Company's disclosures related to offsetting assets and liabilities.

NOTE 7 – OFFSETTING ASSETS AND LIABILITIES

The Company's derivatives and repurchase agreements are subject to underlying agreements with master netting or similar arrangements, which provide for the right of offset in the event of default or in the event of bankruptcy of either party to the transactions. The Company reports its assets and liabilities subject to these arrangements on a gross basis. The following tables present information regarding those assets and liabilities subject to such arrangements as if the Company had presented them on a net basis as of December 31, 2014 and December 31, 2013:

NOTE 8 – 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 December 31, 2014 or December 31, 2013.

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. Generally Level 3 assets are 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 December 31, 2014:

NOTE 9 – SHAREHOLDERS' EQUITY

Preferred Stock

The Company has 2,300,000 shares of its 8.50% Series A Cumulative Redeemable Preferred Stock and 2,250,000 shares of its 7.625% Series B Cumulative Redeemable Preferred Stock issued and outstanding as of December 31, 2014 (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 fourth quarter on January 15, 2015 to shareholders of record as of January 1, 2015.

Common stock repurchased during the period	—		(872,447	)
Balance as of end of period	54,739,111		54,310,484

The Company had 7,416,520 shares of common stock that remain available to offer and sell through its sales agent, JMP Securities LLC, under its "at the market", or "ATM" program, as of December 31, 2014.

The Company's Dividend Reinvestment and Share Purchase Plan ("DRIP") allows registered shareholders to automatically reinvest some or all of their quarterly common stock dividends in shares of the Company’s common stock and provides an opportunity for investors to purchase shares of the Company’s common stock, potentially at a discount to the prevailing market price. Of the 3,000,000 shares reserved for issuance under the Company's DRIP, there were 2,450,145 shares remaining for issuance as of December 31, 2014. The Company declared a fourth quarter common stock dividend of $0.25 per share payable on January 31, 2015 to shareholders of record as of December 31, 2014. There was no discount for shares purchased through the DRIP during the fourth quarter of 2014.

In December 2014, the Company announced that its Board of Directors authorized the repurchase of up to $50,000 of its common stock through December 31, 2016. This new repurchase authorization replaces the Company's prior share repurchase program which was to expire on December 31, 2014.

NOTE 10 – INCOME TAXES

The Company's estimated REIT taxable income before consideration of its net operating loss carryforward was $79,229 for the year ended December 31, 2014, $71,765 for the year ended December 31, 2013, and $73,962 for the year ended December 31, 2012. After common and preferred dividend distributions during those years as well as utilization of the Company's tax net operating loss ("NOL") carryforward to offset taxable earnings, the Company does not expect to incur any income tax liability for the year ended December 31, 2014 and did not incur any material income tax liability for the years ending December 31, 2013 or December 31, 2012.

The Company's estimated NOL carryforward as of December 31, 2014 is $120,016. Because the Company incurred an "ownership change" under Section 382 of the Internal Revenue Code ("Section 382"), the company's ability to utilize its NOL carryforward to offset its taxable income after any required dividend distributions is limited to approximately $13,451 per year with any unused amounts being accumulated and carried forward for use in subsequent years. The NOL will expire beginning in 2020 to the extent it is not used.

After reviewing for any potentially uncertain income tax positions, the Company has concluded that it does not have any uncertain tax positions that meet the recognition or measurement criteria of ASC 740 as of December 31, 2014, December 31, 2013, or December 31, 2012, although its tax returns for those tax years are open to examination by the IRS. In the event that the Company incurs income tax related interest and penalties, its policy is to classify them as a component of provision for income taxes.

NOTE 11 – RELATED PARTY TRANSACTIONS

The Company and DCI Commercial, Inc. ("DCI"), a former affiliate of the Company and formerly known as Dynex Commercial, Inc., were jointly named in litigation regarding the activities of DCI while it was an operating subsidiary of an affiliate of the Company. In May 2013, the Fifth Circuit Court of Appeals in Dallas, Texas (the “Fifth Circuit”) affirmed the trial court’s decision with respect to a take nothing judgment against the Company. With respect to DCI, the Fifth Circuit remanded the case to the trial court for entry of judgment and a $25.6 million damage award against DCI and for a new trial with respect to attorneys’ fees and for costs and pre- and post-judgment interest as determined by the trial court. In December 2000, the Company and DCI entered into a Litigation Cost Sharing Agreement whereby the parties set forth how the costs of defending against such litigation would be shared, and whereby the Company agreed to advance DCI's portion of the costs of defending against such litigation. The Litigation Cost Sharing Agreement remains in effect as of December 31, 2014. DCI costs advanced by the Company are loans and bear simple interest at the rate of Prime plus 8.0% per annum. As of December 31, 2014, the total amount due to the Company under the Litigation Cost Sharing Agreement, including interest, was $9,191, which has been fully reserved for collectibility by the Company. DCI is currently wholly owned by a company unaffiliated with the Company. An executive of the Company is the sole shareholder of this unaffiliated company.

Because the principal related to Agency MBS are 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 December 31, 2014 and December 31, 2013 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 December 31, 2014 or December 31, 2013.

Equity [Abstract]

Preferred Stock [Text Block]

The Company has 2,300,000 shares of its 8.50% Series A Cumulative Redeemable Preferred Stock and 2,250,000 shares of its 7.625% Series B Cumulative Redeemable Preferred Stock issued and outstanding as of December 31, 2014 (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.

Earnings Per Share, Basic and Diluted [Abstract]

Net Income per Common Share

NET INCOME PER COMMON SHARE

Because the Company's Series A Cumulative Redeemable Preferred Stock and Series B Cumulative Redeemable 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 per common share. 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 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.

The following table presents the calculation of the numerator and denominator for both basic and diluted net income per common share for the periods indicated:

	Year Ended
	December 31, 2014					December 31, 2013					December 31, 2012
	Net  Income			Weighted-Average Common Shares		Net  Income			Weighted- Average Common Shares		Net  Income			Weighted- Average Common Shares
Net income	$	27,806				$	68,069				$	74,042
Preferred stock dividends	(9,176		)			(7,902		)			(2,036		)
Net income to common shareholders	18,630			54,701,485		60,167			54,647,643		72,006			53,146,416
Effect of dilutive instruments	—			—		—			—		—			—
Diluted net income to common shareholders	$	18,630		54,701,485		$	60,167		54,647,643		$	72,006		53,146,416
Net income per common share:
Basic and diluted (1)				$	0.34				$	1.10				$	1.35

(1) For the year ended December 31, 2012, the calculation of diluted net income per common shareexcludes the effect of 15,000 unexercised stock option awards because their inclusion would have been anti-dilutive. The Company did not have any potentially dilutive securities outstanding for the years ended December 31, 2014 or December 31, 2013.

Certain items in the prior periods' consolidated financial statements have been reclassified to conform to the current year’s presentation. The Company's consolidated balance sheet as of December 31, 2013 now presents its "securitized mortgage loans, net" and "other investments, net" together as "mortgage loans held for investment, net ". In addition, the Company has combined the presentation of its consolidated statements of income and its consolidated statements of other comprehensive income together as one financial statement which is now titled "consolidated statements of comprehensive income". The Company's "interest income - securitized mortgage loans" and "interest income-other investments" on its consolidated statements of income for the years ended December 31, 2013 and December 31, 2012 are now presented together as "interest income-mortgage loans held for investment, net" on its consolidated statements of comprehensive income for the years ended December 31, 2013 and December 31, 2012. The Company's "amortization and depreciation" on its consolidated statements of cash flows for the years ended December 31, 2013 and December 31, 2012 are now presented as "amortization of investment premiums, net" and "other amortization and depreciation". These presentation changes have no effect on reported total assets, total liabilities, results of operations, or cash flow activities.

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 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 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

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 8 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 3 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.

Effective June 30, 2013, the Company discontinued cash flow hedge accounting for derivative instruments which had previously been accounted for as cash flow hedges under ASC Topic 815. Activity up to and including June 30, 2013 for those agreements previously designated as cash flow hedges was recorded in accordance with cash flow hedge accounting as prescribed by ASC Topic 815, which states that the effective portion of the hedge relationship on an instrument designated as a cash flow hedge is reported in the current period's other comprehensive income while the ineffective portion is immediately reported as a component of the current period’s net income. The balance remaining in AOCI related to the de-designated cash flow hedges is amortized into the Company's net income as a portion of "interest expense" over the remaining life of the interest rate swap agreements. Subsequent to June 30, 2013, changes in the fair value of the Company's derivative instruments, plus periodic settlements, are recorded in the Company's net income as a portion of "gain (loss) on derivative instruments, net".

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 December 31, 2014, the Company does not have any contingencies for which it believes a probable loss has been incurred.

Recent Accounting Pronouncements

In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures, which changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. The guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement, which has resulted in outcomes referred to as off-balance-sheet accounting. All of the Company's repurchase agreement transactions are accounted for as secured borrowings; therefore the accounting changes required by ASU No. 2014-11 do not impact the Company's consolidated financial statements. ASU No. 2014-11 also requires two additional disclosures about repurchase agreements and other similar transactions. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The Company does not account for any of its repurchase agreement transactions as sales; therefore this new disclosure does not impact the Company's current disclosures. The second disclosure requires the following disclosures for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings: a disaggregation of the gross obligation by the class of collateral pledged; the remaining contractual tenor of the agreements; and a discussion of the potential risks associated with the agreements and the related collateral pledged, including obligations arising from a decline in the fair value of the collateral pledged and how those risks are managed. The Company already provides these disclosures in its "Notes to the Consolidated Financial Statements" and within "Liquidity and Capital Resources" in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Annual Report on Form 10-K. The amendments provided in ASU No. 2014-11 are effective for public business entities for the first interim or annual period beginning after December 15, 2014. ASU No. 2014-11 will not have a material impact on the Company's consolidated financial statements.

In addition, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company has not issued and does not anticipate issuing any share-based payments with terms that require a performance-based target; therefore this ASU will not have an impact on the Company's consolidated financial statements.

The FASB issued ASU No. 2014-13, Consolidation (Topic 810): Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity, which provides an alternative to Topic 820, Fair Value Measurement, for measuring the financial assets and the financial liabilities of a consolidated collateralized financing entity to eliminate the difference in the fair value of the financial assets of a collateralized financing entity, as determined under GAAP, when they differ from the fair value of its financial liabilities even when the financial liabilities have recourse only to the financial assets. When the measurement alternative is elected, both the financial assets and the financial liabilities of the collateralized financing entity should be measured using the more observable of the fair value of the financial assets or the fair value of the financial liabilities. The amendments clarify that when the measurement alternative is elected, a reporting entity's consolidated net income (loss) should reflect the reporting entity's own economic interests in the collateralized financing entity, including; (1) changes in the fair value of the beneficial interests retained by the reporting entity, and (2) beneficial interests that represent compensation for services. The measurement alternative provided in ASU No. 2014-13 may be applied using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the annual period of adoption. The amendments may also be applied retrospectively to all relevant prior periods beginning with the annual period in which ASU No. 2009-17 was initially adopted. ASU No. 2014-13 is effective for public entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, and early adoption is permitted as of the beginning of an annual period. Management has evaluated ASU No. 2014-13 and has determined that if the Company elects to adopt this measurement alternative in the future for its currently existing consolidated collateralized financing entity, it will not have a material impact on the Company's consolidated financial statements.

The FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, which provides guidance about management's responsibility under GAAP to evaluate whether there is substantial doubt about an organization's ability to continue as a going concern and to provide related footnote disclosures. Specifically, the ASU (1) provides a definition of the term "substantial doubt", (2) requires an evaluation by management every reporting period including interim periods, (3) provides principles for considering the mitigating effect of management's plans, (4) requires certain disclosures when substantial doubt exists regardless of the success of any mitigating plans or actions, (5) requires an express statement and other disclosures when substantial doubt is not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued. The amendments in this ASU are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. Management intends to comply with the requirements set forth in ASU No. 2014-15.

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:

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 $2,577 remaining in AOCI on the Company's consolidated balance sheet as of December 31, 2014 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. Because of differing market values and maturities at the time of cash flow hedge de-designation, the balance remaining in AOCI is comprised of both unrealized gains and unrealized losses which will not be recognized in net income equally over time. All forecasted transactions associated with interest rate swap agreements previously designated as cash flow hedges are expected to occur. No amounts have been reclassified to net income in any period in connection with forecasted transactions that are no longer considered probable of occurring. 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 $3,460.

The table below describes the components of the reclassification adjustments out of AOCI related to certain interest rate swaps that were formerly designated as cash flow hedges and recognized as a portion of "interest expense" on the Company statements of comprehensive income for the periods indicated:

	Year Ended

Total reclassification adjustment related to cash flow hedges	$	6,788	$	13,989	$	14,448

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 GAAP 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 December 31, 2014.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

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 consolidated financial statements of Dynex Capital, Inc. and its qualified real estate investment trust ("REIT") subsidiaries and its taxable REIT subsidiary (together, "Dynex" or the "Company") have been prepared in accordance with the generally accepted accounting principles in the United States ("GAAP") and the instructions to the Annual Report on Form 10-K and Article 3 of Regulation S-X promulgated by the Securities and Exchange Commission (the "SEC").

Reclassifications [Policy Text Block]

Reclassifications

Certain items in the prior periods' consolidated financial statements have been reclassified to conform to the current year’s presentation. The Company's consolidated balance sheet as of December 31, 2013 now presents its "securitized mortgage loans, net" and "other investments, net" together as "mortgage loans held for investment, net ". In addition, the Company has combined the presentation of its consolidated statements of income and its consolidated statements of other comprehensive income together as one financial statement which is now titled "consolidated statements of comprehensive income". The Company's "interest income - securitized mortgage loans" and "interest income-other investments" on its consolidated statements of income for the years ended December 31, 2013 and December 31, 2012 are now presented together as "interest income-mortgage loans held for investment, net" on its consolidated statements of comprehensive income for the years ended December 31, 2013 and December 31, 2012. The Company's "amortization and depreciation" on its consolidated statements of cash flows for the years ended December 31, 2013 and December 31, 2012 are now presented as "amortization of investment premiums, net" and "other amortization and depreciation". These presentation changes have no effect on reported total assets, total liabilities, results of operations, or cash flow activities.

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 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 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 8 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 3 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.

Effective June 30, 2013, the Company discontinued cash flow hedge accounting for derivative instruments which had previously been accounted for as cash flow hedges under ASC Topic 815. Activity up to and including June 30, 2013 for those agreements previously designated as cash flow hedges was recorded in accordance with cash flow hedge accounting as prescribed by ASC Topic 815, which states that the effective portion of the hedge relationship on an instrument designated as a cash flow hedge is reported in the current period's other comprehensive income while the ineffective portion is immediately reported as a component of the current period’s net income. The balance remaining in AOCI related to the de-designated cash flow hedges is amortized into the Company's net income as a portion of "interest expense" over the remaining life of the interest rate swap agreements. Subsequent to June 30, 2013, changes in the fair value of the Company's derivative instruments, plus periodic settlements, are recorded in the Company's net income as a portion of "gain (loss) on derivative instruments, net".

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 December 31, 2014, 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

In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures, which changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. The guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement, which has resulted in outcomes referred to as off-balance-sheet accounting. All of the Company's repurchase agreement transactions are accounted for as secured borrowings; therefore the accounting changes required by ASU No. 2014-11 do not impact the Company's consolidated financial statements. ASU No. 2014-11 also requires two additional disclosures about repurchase agreements and other similar transactions. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The Company does not account for any of its repurchase agreement transactions as sales; therefore this new disclosure does not impact the Company's current disclosures. The second disclosure requires the following disclosures for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings: a disaggregation of the gross obligation by the class of collateral pledged; the remaining contractual tenor of the agreements; and a discussion of the potential risks associated with the agreements and the related collateral pledged, including obligations arising from a decline in the fair value of the collateral pledged and how those risks are managed. The Company already provides these disclosures in its "Notes to the Consolidated Financial Statements" and within "Liquidity and Capital Resources" in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Annual Report on Form 10-K. The amendments provided in ASU No. 2014-11 are effective for public business entities for the first interim or annual period beginning after December 15, 2014. ASU No. 2014-11 will not have a material impact on the Company's consolidated financial statements.

In addition, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company has not issued and does not anticipate issuing any share-based payments with terms that require a performance-based target; therefore this ASU will not have an impact on the Company's consolidated financial statements.

The FASB issued ASU No. 2014-13, Consolidation (Topic 810): Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity, which provides an alternative to Topic 820, Fair Value Measurement, for measuring the financial assets and the financial liabilities of a consolidated collateralized financing entity to eliminate the difference in the fair value of the financial assets of a collateralized financing entity, as determined under GAAP, when they differ from the fair value of its financial liabilities even when the financial liabilities have recourse only to the financial assets. When the measurement alternative is elected, both the financial assets and the financial liabilities of the collateralized financing entity should be measured using the more observable of the fair value of the financial assets or the fair value of the financial liabilities. The amendments clarify that when the measurement alternative is elected, a reporting entity's consolidated net income (loss) should reflect the reporting entity's own economic interests in the collateralized financing entity, including; (1) changes in the fair value of the beneficial interests retained by the reporting entity, and (2) beneficial interests that represent compensation for services. The measurement alternative provided in ASU No. 2014-13 may be applied using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the annual period of adoption. The amendments may also be applied retrospectively to all relevant prior periods beginning with the annual period in which ASU No. 2009-17 was initially adopted. ASU No. 2014-13 is effective for public entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, and early adoption is permitted as of the beginning of an annual period. Management has evaluated ASU No. 2014-13 and has determined that if the Company elects to adopt this measurement alternative in the future for its currently existing consolidated collateralized financing entity, it will not have a material impact on the Company's consolidated financial statements.

The FASB issued ASU No. 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, which provides guidance about management's responsibility under GAAP to evaluate whether there is substantial doubt about an organization's ability to continue as a going concern and to provide related footnote disclosures. Specifically, the ASU (1) provides a definition of the term "substantial doubt", (2) requires an evaluation by management every reporting period including interim periods, (3) provides principles for considering the mitigating effect of management's plans, (4) requires certain disclosures when substantial doubt exists regardless of the success of any mitigating plans or actions, (5) requires an express statement and other disclosures when substantial doubt is not alleviated, and (6) requires an assessment for a period of one year after the date that the financial statements are issued. The amendments in this ASU are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. Management intends to comply with the requirements set forth in ASU No. 2014-15.

INCOME TAXES

The Company's estimated REIT taxable income before consideration of its net operating loss carryforward was $79,229 for the year ended December 31, 2014, $71,765 for the year ended December 31, 2013, and $73,962 for the year ended December 31, 2012. After common and preferred dividend distributions during those years as well as utilization of the Company's tax net operating loss ("NOL") carryforward to offset taxable earnings, the Company does not expect to incur any income tax liability for the year ended December 31, 2014 and did not incur any material income tax liability for the years ending December 31, 2013 or December 31, 2012.

The Company's estimated NOL carryforward as of December 31, 2014 is $120,016. Because the Company incurred an "ownership change" under Section 382 of the Internal Revenue Code ("Section 382"), the company's ability to utilize its NOL carryforward to offset its taxable income after any required dividend distributions is limited to approximately $13,451 per year with any unused amounts being accumulated and carried forward for use in subsequent years. The NOL will expire beginning in 2020 to the extent it is not used.

After reviewing for any potentially uncertain income tax positions, the Company has concluded that it does not have any uncertain tax positions that meet the recognition or measurement criteria of ASC 740 as of December 31, 2014, December 31, 2013, or December 31, 2012, although its tax returns for those tax years are open to examination by the IRS. In the event that the Company incurs income tax related interest and penalties, its policy is to classify them as a component of provision for income taxes.

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:

	December 31, 2014

Total liabilities carried at fair value	$	6,681	$	5,345	$	1,336	$	—

The Company did not have assets or liabilities measured at fair value on a non-recurring basis as of December 31, 2014 or December 31, 2013.

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. Generally Level 3 assets are 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 December 31, 2014:

	Quantitative Information about Level 3 Fair Value Measurements (1)
	Prepayment Speed	Default Rate		Severity		Discount Rate

Shareholders' Equity

SHAREHOLDERS' EQUITY

Preferred Stock

The Company has 2,300,000 shares of its 8.50% Series A Cumulative Redeemable Preferred Stock and 2,250,000 shares of its 7.625% Series B Cumulative Redeemable Preferred Stock issued and outstanding as of December 31, 2014 (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 fourth quarter on January 15, 2015 to shareholders of record as of January 1, 2015.

The Company had 7,416,520 shares of common stock that remain available to offer and sell through its sales agent, JMP Securities LLC, under its "at the market", or "ATM" program, as of December 31, 2014.

The Company's Dividend Reinvestment and Share Purchase Plan ("DRIP") allows registered shareholders to automatically reinvest some or all of their quarterly common stock dividends in shares of the Company’s common stock and provides an opportunity for investors to purchase shares of the Company’s common stock, potentially at a discount to the prevailing market price. Of the 3,000,000 shares reserved for issuance under the Company's DRIP, there were 2,450,145 shares remaining for issuance as of December 31, 2014. The Company declared a fourth quarter common stock dividend of $0.25 per share payable on January 31, 2015 to shareholders of record as of December 31, 2014. There was no discount for shares purchased through the DRIP during the fourth quarter of 2014.

In December 2014, the Company announced that its Board of Directors authorized the repurchase of up to $50,000 of its common stock through December 31, 2016. This new repurchase authorization replaces the Company's prior share repurchase program which was to expire on December 31, 2014.

2009 Stock and Incentive Plan. Of the 2,500,000 shares of common stock authorized for issuance under its 2009 Stock and Incentive Plan, the Company had 1,078,908 available for issuance as of December 31, 2014.

RELATED PARTY TRANSACTIONS

The Company and DCI Commercial, Inc. ("DCI"), a former affiliate of the Company and formerly known as Dynex Commercial, Inc., were jointly named in litigation regarding the activities of DCI while it was an operating subsidiary of an affiliate of the Company. In May 2013, the Fifth Circuit Court of Appeals in Dallas, Texas (the “Fifth Circuit”) affirmed the trial court’s decision with respect to a take nothing judgment against the Company. With respect to DCI, the Fifth Circuit remanded the case to the trial court for entry of judgment and a $25.6 million damage award against DCI and for a new trial with respect to attorneys’ fees and for costs and pre- and post-judgment interest as determined by the trial court. In December 2000, the Company and DCI entered into a Litigation Cost Sharing Agreement whereby the parties set forth how the costs of defending against such litigation would be shared, and whereby the Company agreed to advance DCI's portion of the costs of defending against such litigation. The Litigation Cost Sharing Agreement remains in effect as of December 31, 2014. DCI costs advanced by the Company are loans and bear simple interest at the rate of Prime plus 8.0% per annum. As of December 31, 2014, the total amount due to the Company under the Litigation Cost Sharing Agreement, including interest, was $9,191, which has been fully reserved for collectibility by the Company. DCI is currently wholly owned by a company unaffiliated with the Company. An executive of the Company is the sole shareholder of this unaffiliated company.

Mortgage Loans Held for Investment, Net [Abstract]

Mortgage Loans Held for Investment, Net [Text Block]

The Company's mortgage loans held for investment, net consist of securitized and unsecuritized mortgage loans originated or purchased by the Company from 1992 through 1998. The following table provides detail by type of collateral as of the periods indicated:

	December 31, 2014			December 31, 2013
Single-family mortgage loans held for investment, amortized cost	$	30,214		$	35,328
Commercial mortgage loans held for investment, amortized cost	9,736			20,352
Allowance for loan losses	(250		)	(257		)
Total mortgage loans held for investment, net	$	39,700		$	55,423

Commercial securitized mortgage loans are evaluated individually for impairment when the debt service coverage ratio on the mortgage loan is less than 1:1 or when the mortgage loan is delinquent. Commercial mortgage loans not evaluated for individual impairment are evaluated for a general allowance. There were no securitized commercial mortgage loans identified as seriously delinquent (60 or more days past due) on the Company's consolidated balance sheets as of December 31, 2014 or as of December 31, 2013.

Single-family mortgage loans are considered homogeneous and are evaluated on a pool basis for a general allowance. The unpaid principal balance of the Company's securitized single-family mortgage loans identified as seriously delinquent as of December 31, 2014 was $2,221 compared to $2,758 as of December 31, 2013. The Company continues to accrue interest on its seriously delinquent securitized single-family mortgage loans because the primary servicer continues to advance the interest and/or principal due on the loan.

The Company considers various factors in determining its specific and general allowance requirements, including whether a loan is delinquent, the Company’s historical experience with similar types of loans, historical cure rates of delinquent loans, and historical and anticipated loss severity of the mortgage loans as they are liquidated. The factors may differ by mortgage loan type (e.g., single-family versus commercial) and collateral type (e.g., multifamily versus office property). The allowance for loan losses is evaluated and adjusted periodically by management based on the actual and estimated timing and amount of probable credit losses, using the above factors, as well as industry loss experience.

The majority of the Company's mortgage loans held for investment, net are securitized mortgage loans, of which $11,902 of principal is pledged as collateral for an outstanding class of the Company's single-family securitization financing bond, which is recorded on the Company's balance sheet as "non-recourse collateralized financing". The interest rate on this bond is based on 1-month LIBOR plus 0.30% and has an estimated life remaining of less than 3 years as of December 31, 2014. The principal balance outstanding as of December 31, 2014 is $10,967 compared to $13,134 as of December 31, 2013.
