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 specified pools of Agency and non-Agency mortgage-backed securities (“MBS”) consisting of residential MBS (“RMBS”), commercial MBS (“CMBS”) and CMBS interest-only ("IO") securities 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"). We also invest in other types of mortgage-related securities, such as to-be-announced (“TBA”) forward contracts for the purchase or sale of generic (also referred to as "non-specified") pools of Agency MBS.

Basis of Presentation

The accompanying unaudited consolidated financial statements of Dynex Capital, Inc. and its subsidiaries (together, “Dynex” or, as appropriate, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10, Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all significant adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the consolidated financial statements have been included. Operating results for the three months endedSeptember 30, 2017 are not necessarily indicative of the results that may be expected for any other interim periods or for the entire year ending December 31, 2017. The unaudited consolidated financial statements included herein should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC.

Consolidation

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

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, amortization of premiums and discounts, fair value measurements of its investments, and other-than-temporary impairments. 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 ("NOL") 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 capital gains that is distributed as dividends to shareholders.

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

Net Income (Loss) Per Common Share

The Company calculates basic net income (loss) per common share by dividing net income (loss) to common shareholders for the period by weighted-average shares of common stock outstanding for that period. The Company did not have any potentially dilutive securities outstanding during the three or nine months endedSeptember 30, 2017 or September 30, 2016.

Holders of unvested shares of the Company's issued and outstanding restricted common stock are eligible to receive non-forfeitable dividends. As such, these unvested shares are considered participating securities as per ASC Topic 260-10 and therefore are included in the computation of basic net income (loss) per common 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 represents one unrestricted share of common stock.

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

Cash and Cash Equivalents

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

Restricted Cash

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

The Company early adopted Accounting Standards Update ("ASU") No. 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash, which requires amounts generally described as restricted cash or restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows. Because this ASU is to be applied retrospectively to each period presented, "net cash and cash equivalents used in financing activities" on the Company's consolidated statement of cash flows for the nine months endedSeptember 30, 2016 now omits "increase in restricted cash" previously reported in the Quarterly Report on Form 10-Q for that period, and that increase is now included within "net increase in cash, cash equivalents, and restricted cash" for that period in order to conform to the current period's presentation.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported on the Company's consolidated balance sheet as of September 30, 2017 that sum to the total of the same such amounts shown on the Company's consolidated statement of cash flows for the nine months endedSeptember 30, 2017:

	September 30, 2017
Cash and cash equivalents	$	117,702
Restricted cash	43,987
Total cash, cash equivalents, and restricted cash shown on consolidated statement of cash flows	$	161,689

Mortgage-Backed Securities

The Company's investments in Agency and non-Agency RMBS, CMBS, and CMBS IO securities are designated as available-for-sale ("AFS") and are recorded at fair value on the Company's consolidated balance sheet. Changes in unrealized gain (loss) on the Company's MBS are reported in other comprehensive income ("OCI") until it is sold, matures, or is 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 as collateral 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 the Company's Agency MBS as well as any non-Agency MBS rated 'AA' and higher at the time of purchase are amortized or accreted into interest income over the expected life of such securities using the effective yield method, and adjustments to premium amortization and discount accretion are made for actual cash payments. The Company may also adjust premium amortization and discount accretion for changes in projected future cash payments. The Company's projections of future cash payments are based on input and analysis received from external sources and internal models, and include assumptions about the amount and timing of loan prepayment rates, fluctuations in interest rates, credit losses, 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 does not estimate future prepayments on its fixed-rate Agency RMBS.

The Company holds certain non-Agency MBS that had credit ratings of less than 'AA' at the time of purchase or were not rated by any of the nationally recognized credit rating agencies. A portion of these non-Agency MBS were purchased at discounts to their par value, which management does not believe to be substantial. The discount is accreted into income over the security's expected life based on management's estimate of the security's projected cash flows. 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 5 for further discussion of MBS fair value measurements.

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

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

Repurchase Agreements

The Company's repurchase agreements, which are used to finance its purchases of MBS, 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 include interest rate swaps and forward contracts for the purchase or sale of generic Agency RMBS, commonly referred to as "TBA securities" or "TBA contracts". Derivative instruments are accounted for at the fair value of their unit of account. Derivative instruments in a gain position are reported as derivative assets and derivative instruments in a loss position are reported as derivative liabilities on the Company's consolidated balance sheet. All periodic interest costs and changes in fair value of derivative instruments, including gains and losses realized upon termination, maturity, or settlement are recorded in "gain (loss) on derivative instruments, net" on the Company's consolidated statement of comprehensive income. Cash receipts and payments related to derivative instruments are classified in the investing activities section of our consolidated statements of cash flows in accordance with the underlying nature or purpose of the derivative transactions.

Our interest rate swap agreements are privately negotiated in the over-the-counter ("OTC") market and the majority of these agreements are centrally cleared through the Chicago Mercantile Exchange ("CME") with the rest being subject to bilateral agreements between the Company and the swap counterparty. The Company's CME cleared swaps require that the Company post initial margin as determined by the CME, and in addition, variation margin is exchanged, typically in cash, for changes in the fair value of the CME cleared swaps. Beginning in January 2017, as a result of a change in the CME's rulebook, the exchange of variation margin for CME cleared swaps is legally considered to be the settlement of the derivative itself as opposed to a pledge of collateral. Accordingly, beginning in 2017, the Company accounts for the daily exchange of variation margin associated with its CME cleared interest rate swaps as a direct increase or decrease to the carrying value of the related derivative asset or liability. The carrying value of CME cleared interest rate swaps on the Company's consolidated balance sheets is the unsettled fair value of those instruments.

A TBA security is a forward contract for the purchase or sale of a generic Agency MBS at a predetermined price with certain principal and interest terms and certain types of collateral, but the particular Agency securities to be delivered are not identified until shortly before the TBA settlement date. The Company executes TBA dollar roll transactions which effectively delay the settlement of a forward purchase of a TBA Agency RMBS by entering into an offsetting short position (referred to as a "pair off"), net settling the paired-off positions in cash, and simultaneously entering a similar TBA contract for a later settlement date. TBA securities purchased for a forward settlement month are generally priced at a discount relative to TBA securities sold for settlement in the current month. This discount, often referred to as “drop income” is the economic equivalent of net interest income on the underlying Agency securities over the roll period (interest income less implied financing cost).

The Company accounts for TBA securities as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA contract that its settlement will result in physical delivery of the underlying Agency RMBS, or the individual TBA contract will not settle in the shortest time period possible.

Please refer to Note 4 for additional information regarding the Company's derivative instruments as well as Note 5 for information on how the fair value of these instruments are calculated.

Share-Based Compensation

Pursuant to the Company’s 2009 Stock and Incentive Plan, 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 time-based restricted stock 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 issued to its employees, officers, and directors.

Contingencies

In the normal course of business, there may be 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. The Company recognizes a liability 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.

Recent Accounting Pronouncements

The Financial Accounting Standards Board ("FASB") issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs, which shortens the amortization period for certain callable debt securities held at a premium, requiring the premium to be amortized to the earliest call date. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and early adoption is permitted. The amendments in this Update should be applied using the modified-retrospective transition approach and will require disclosures for the change in accounting principle. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements.

FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which contains significant amendments to hedge accounting with the main objective of better aligning an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both non-financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASU also includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness as well as changes to current disclosure requirements. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, and early adoption is permitted. All transition requirements and elections will be applied to hedging relationships existing on the date of adoption. The effect of adoption will be reflected as of the beginning of the fiscal year of adoption, and the amended presentation and disclosure guidance is required only prospectively. The Company does not currently apply hedge accounting, but is evaluating the impact this ASU would have on its consolidated financial statements if the Company elects to adopt hedge accounting in the future.

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

(2) The notional balance for the Agency CMBS IO and non-Agency CMBS IO was $13,106,912 and $10,884,964, respectively, as of December 31, 2016.

Actual maturities of MBS are affected by the contractual lives of the underlying mortgage collateral, periodic payments of principal, prepayments of principal, and the payment priority structure of the security; therefore, actual maturities are generally shorter than the securities' stated contractual maturities.

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

	September 30, 2017						December 31, 2016
	Fair Value		Gross Unrealized Losses			# of Securities	Fair Value		Gross Unrealized Losses			# of Securities
Continuous unrealized loss position for less than 12 months:

Non-Agency MBS	15,749		(199		)	11	81,660		(2,332		)	26

Because the principal related to Agency MBS is guaranteed by the government-sponsored entities Fannie Mae and Freddie Mac which have the implicit guarantee of the U.S. government, the Company does not consider any of the unrealized

losses on its Agency MBS to be credit related. Although the unrealized losses are not credit related, the Company assesses its ability and intent to hold any Agency MBS with an unrealized loss until the recovery in its value in accordance with GAAP. This assessment is based on the amount of the unrealized loss and significance of the related investment as well as the Company’s leverage and liquidity position. Based on this analysis, the Company has determined that the unrealized losses on its Agency MBS as of September 30, 2017 and December 31, 2016 were temporary.

The Company 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 the non-Agency MBS, the credit characteristics of the mortgage loans collateralizing these securities, and the estimated future cash flows including projected collateral losses. The Company performed this evaluation for its 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 September 30, 2017 or December 31, 2016.

NOTE 3 – REPURCHASE AGREEMENTS

The Company’s repurchase agreements outstanding as of September 30, 2017 and December 31, 2016 are summarized in the following tables:

The following table lists the counterparties with whom the Company had over 10% of its shareholders' equity at risk (defined as the excess of collateral pledged over the borrowings outstanding):

	September 30, 2017
Counterparty Name	Balance		Weighted Average Rate		Equity at Risk
Wells Fargo Bank, N. A. and affiliates	$	349,965	2.10	%	$	57,992

Of the amount outstanding with Wells Fargo Bank, N.A. and affiliates, $343,780 is under a committed repurchase facility which has an aggregate maximum borrowing capacity of $400,000 and is scheduled to mature on May 12, 2019, 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 September 30, 2017 was 2.10%.

As of September 30, 2017, the Company had repurchase agreement amounts outstanding with 18 of its 34 available repurchase agreement 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 and earnings, 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 full compliance with all covenants as of September 30, 2017.

The Company's 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 repurchase agreements to these arrangements on a gross basis. The following tables present information regarding the Company's repurchase agreements as if the Company had presented them on a net basis as of September 30, 2017 and December 31, 2016:

	Gross Amount of Recognized Liabilities		Gross Amount Offset in the Balance Sheet		Net Amount of Liabilities Presented in the Balance Sheet		Gross Amount Not Offset in the Balance Sheet (1)					Net Amount

(1) Amounts disclosed for collateral received by or posted to the same counterparty include cash and the fair value of MBS up to and not exceeding the net amount of the asset or liability presented in the balance sheet. The fair value of the actual collateral received by or posted to the same counterparty may exceed the amounts presented.

Please see Note 4 for information related to the Company's derivatives which are also subject to underlying agreements with master netting or similar arrangements.

NOTE 4 – DERIVATIVES

     The Company's derivative instruments include interest rate swaps and TBA securities. The Company utilizes interest rate swaps to economically hedge a portion of its exposure to interest rate risk in order 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 some portion of the Company's earnings from rising interest rates. The Company invests in TBA securities for the purchase or sale of Agency RMBS on a non-specified pool basis. TBA securities are forward contracts which are accounted for as derivative instruments; however, management views TBA securities as the economic equivalent of investing in and financing generic Agency fixed-rate RMBS through the repurchase agreement markets. 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 fair value by type of derivative instrument on the Company's consolidated balance sheets as of the dates indicated:  

		September 30, 2017			December 31, 2016
Type of Derivative Instruments	Balance Sheet Location	Fair Value			Fair Value (1)
Interest rate swaps	Derivative assets	$	368		$	28,534
TBA securities	Derivative assets	—			—

Interest rate swaps	Derivative liabilities	$	—		$	(6,922	)
TBA securities	Derivative liabilities	(133		)	—
		$	(133	)	$	(6,922	)

(1) Refer to Note 1 regarding information on a change in the CME rulebook. Amounts reported on the consolidated balance sheet as of September 30, 2017 for its interest rate swaps reflect the netting of the derivative asset or liability with the related collateral received or posted, respectively. The net amounts comparable to September 30, 2017 for the derivative asset and derivative liabilities as of December 31, 2016 were $104 and $(576), respectively.

The following tables present information about the Company's interest rate swaps as of the dates indicated:

Gain (loss) on derivative instruments, net	$	5,993		$	2,409		$	(9,634	)	$	(62,153	)

There is a net unrealized gain of $450 remaining in AOCI on the Company's consolidated balance sheet as of September 30, 2017 which represents the activity related to 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 an adjustment to "interest expense" over the remaining contractual life of the agreements. The Company estimates a credit of $210 will be reclassified to net income as a reduction of "interest expense" within the next 12 months.

A portion of the Company's interest rate swaps were entered into under bilateral agreements which contain cross-default provisions with other agreements between the parties. In addition, these bilateral agreements contain financial and operational covenants similar to those contained in our repurchase agreements as described in Note 3. The Company was in compliance with all covenants with respect to bilateral agreements under which interest rate swaps were entered into as of September 30, 2017.

The Company's derivatives 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 derivative assets and liabilities subject to these arrangements on a gross basis. The following tables present information regarding those derivative assets and liabilities subject to such arrangements as if the Company had presented them on a net basis as of September 30, 2017 and December 31, 2016:

The fair value of the actual collateral received by or posted to the same counterparty may exceed the amounts presented.

Please see Note 3 for information related to the Company's repurchase agreements which are also subject to underlying agreements with master netting or similar arrangements.

NOTE 5 – 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 Company reviews the classification of its financial instruments within the fair value hierarchy on a quarterly basis, and management may conclude that its financial instruments should be reclassified to a different level in the future if a change in type of inputs occurs. 

The following table presents the fair value of the Company’s financial instruments 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 fair value measurements for a majority of the Company's MBS are considered Level 2. These Level 2 securities are substantially similar to securities that either are actively traded or have been recently traded in their respective markets. The Company determines the fair value of its Level 2 securities based on prices received from the Company's primary pricing service as well as other pricing services and brokers. The Company evaluates the third party prices it receives to assess their reasonableness. Although the Company does not adjust third party prices, they may be excluded from use in the determination of a security's fair value if they are significantly different from other observable market data. In valuing a security, the primary pricing service uses either a market approach, which uses observable prices and other relevant information that is generated by

market transactions of identical or similar securities, or an income approach, which uses valuation techniques to convert future amounts to a single, discounted present value amount. The Company also reviews the assumptions and inputs utilized in the valuation techniques of its primary pricing service. Examples of these observable inputs and assumptions include market interest rates, credit spreads, and projected prepayment speeds, among other things.

The fair value of interest rate swaps are measured 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 as of September 30, 2017 and December 31, 2016. The fair value of TBA securities are estimated using methods similar those used to fair value the Company's Level 2 MBS.

The Company owns certain non-Agency MBS for which there are not sufficiently recent trades of substantially similar securities, and their fair value measurements are thus considered Level 3. The Company determines the fair value of its Level 3 securities by discounting the estimated future cash flows derived from cash flow models using significant inputs which are determined by the Company when market observable inputs are not available. 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 may result in a significantly different fair value measurement. Level 3 assets are generally most sensitive to the default rate and severity assumptions.

The activity of the instruments measured at fair value on a recurring basis using Level 3 inputs is presented in the following table for the period indicated:

	Level 3 Fair Value
	Non-Agency CMBS			Non-Agency RMBS			Total

EXECUTIVE OVERVIEW

Company Overview

We are an internally managed mortgage real estate investment trust, or mortgage REIT, which invests in residential and commercial mortgage-backed securities on a leveraged basis. Our common stock is traded on the New York Stock Exchange ("NYSE") under the symbol "DX". 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 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".

We invest in Agency and non-Agency mortgage-backed securities (“MBS”) consisting of residential MBS (“RMBS”), commercial MBS (“CMBS”) and 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 investments in non-Agency MBS are generally higher quality senior or mezzanine classes (typically rated 'A' or better by one or more of the nationally recognized statistical rating organizations) because they are typically more liquid (i.e., they are more easily converted into cash either through sales or pledges as collateral for repurchase agreement borrowings) and have less exposure to credit losses than lower-rated non-Agency MBS.

We invest and manage our capital pursuant to Operating Policies approved by our Board of Directors. We use leverage to enhance the returns on our invested capital by pledging our investments as collateral for borrowings such as repurchase agreements as discussed further below. We also use derivative instruments to attempt to mitigate our exposure to adverse changes in interest rates as discussed further below.

RMBS. Our Agency RMBS investments include MBS collateralized by fixed-rate mortgage loans as well as adjustable-rate mortgage loans ("ARMs"), which have interest rates that generally adjust at least annually to an increment over a specified interest rate index. Agency ARMs also include 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. Substantially all of our ARMs reset based on the one-year LIBOR index. We sold the majority of our non-Agency RMBS during the second quarter of 2017 because these investments were within a year of their maturity. We are not currently re-investing capital into non-Agency RMBS due to the lack of available securities of this type with attractive risk-adjusted returns.

In the second quarter of 2017, we began entering into forward contracts for the purchase of TBA securities as a means of investing in and financing non-specified fixed-rate Agency RMBS. A TBA security is a forward contract for the purchase or sale of a fixed-rate Agency MBS at a predetermined price with certain principal and interest terms and certain types of collateral, but the particular Agency securities to be delivered are not identified until shortly before the TBA settlement date. The financing for TBA securities is implied through our use of TBA dollar roll transactions whereby we enter into an offsetting short position, net settle the paired-off positions in cash, and simultaneously enter into a similar TBA contract for a later settlement date. TBA securities purchased for a forward settlement month are generally priced at a discount relative to TBA securities sold for settlement in the current month. This discount, often referred to as “drop income,” is the economic equivalent of net interest income on the underlying Agency securities over the roll period (interest income less implied financing cost). We account for TBA securities as derivative instruments because we cannot assert that it is probable at inception and throughout the term of an individual TBA contract that its settlement will result in physical delivery of the underlying Agency RMBS, or the individual TBA contract will not settle in the shortest time period possible.

CMBS. The majority of our CMBS investments are fixed-rate Agency-issued securities backed by multifamily housing loans. The remainder of our CMBS portfolio contains both Agency and non-Agency issued securities backed by other commercial real estate property types such as office building, retail, hospitality, and health care. Loans underlying CMBS generally are geographically diverse, are fixed-rate, mature in eight to eighteen years and have amortization terms of up to 30 years. 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. CMBS IO are interest-only securities issued as part of a CMBS securitization and represent the right to receive a portion of the monthly interest payments (but not principal cash flows) on the unpaid principal balance of the underlying pool of commercial mortgage loans. We invest in both Agency-issued and non-Agency issued CMBS IO. The loans collateralizing CMBS IO pools are very similar in composition to the pools of loans that generally collateralize CMBS as discussed above. Since CMBS IO 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. Most loans in these securities have some form of prepayment protection from early repayment including absolute loan prepayment lock-outs, loan prepayment penalties, or yield maintenance requirements similar to CMBS described above. 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, and therefore yields on CMBS IO investments are dependent upon the underlying loan performance. Because Agency-issued MBS generally contain higher credit quality loans, Agency CMBS IO are expected to have a lower risk of default than non-Agency CMBS IO. Our CMBS IO investments are investment grade-rated with the majority rated 'AAA' by at least one of the nationally recognized statistical rating organizations.

Financing. We finance our investments primarily through the use of uncommitted repurchase agreements which are provided principally by major financial institutions and broker-dealers. We pledge our MBS as collateral to secure the amounts borrowed from our counterparties. These repurchase agreements generally have original terms to maturity of overnight to six months, though in some instances we may enter into longer-dated maturities depending on market conditions. We pay interest on our repurchase agreement borrowings at a rate 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. One of our repurchase agreement lenders provides a committed repurchase agreement financing facility to us with an aggregate borrowing capacity of $400.0 million that expires in May 2019.

TBA dollar roll transactions require us to post initial margin (though typically the amount is less than the initial margin amount for repurchase agreements) and variation margin for fluctuations in fair value of the TBA securities. These dollar roll transactions have an implied financing rate which changes with market conditions, expected prepayment speeds, and the underlying demand for Agency RMBS in a given delivery period.

Hedging. We currently use interest rate swaps to hedge our exposure to changes in interest rates. Such exposure results from our ownership of hybrid and fixed-rate investments that are financed with repurchase agreements which have significantly shorter maturities than the weighted average life of these investments. Changes in interest rates can impact the market value of our investments and our net interest income, thereby ultimately impacting book value per common share. We frequently adjust

our hedging portfolio based on our expectation of future interest rates, including the absolute level of rates and the slope of the yield curve versus market expectations.

Factors that Affect Our Results of Operations and Financial Condition

Our financial performance is driven principally by the performance of our investment portfolio and related financing and hedging activity. Management focuses on net interest income, net income, comprehensive income, book value per common share, and core net operating income to common shareholders (a non-GAAP measure) as measurements of our financial performance. Our financial performance may be impacted by multiple factors, including but not limited to, macroeconomic conditions, geopolitical conditions, central bank and government policy, the absolute level of interest rates and the relative slope of interest rate curves, changes in market expectations of future interest rates, actual and estimated future prepayment rates on our investments, competition for investments, economic conditions and their impact on the credit performance of our investments, and market required yields as reflected by market spreads. All of these factors are influenced by market forces beyond our control and may be exacerbated during periods of market volatility.

Our performance may also be impacted by other factors such as the availability and cost of financing and the state of the overall credit markets. Reductions in or limitations of financing for our investments could force us to sell assets, potentially at losses particularly if there is a period of stress in the funding markets as was experienced by the industry during the 2008 financial crisis. Other factors that could also impact our business include changes in regulatory requirements, including requirements to qualify for registration under the 1940 Act and REIT requirements.

We believe that regulatory impacts on financial institutions, many of which are our trading and financing counterparties, continue to pose a threat to the overall liquidity in the capital markets. Restrictions on market-making activities of large U.S. financial institutions could result in reduced liquidity in times of market stress. The Federal Reserve has begun curtailing its reinvestment of principal payments received on its Agency RMBS and U.S. Treasury portfolios, which could result in volatile asset prices. Other foreign central bank asset purchases have also favorably impacted asset prices in the U.S., including securities in which we invest. Finally, the market liquidity of our investments and the financing markets could be negatively impacted if the Federal Reserve's Federal Open Market Committee (or "FOMC") suddenly changes market expectations of the target Federal Funds Rate or takes other actions which have the effect of tightening monetary policy.

To complement the performance of our investment portfolio, we regularly review our existing operations to determine whether our investment strategy or business model should change, including through a change in our investment portfolio, our targeted investments, and our risk position. We may also consider reallocating our capital resources to other assets or portfolios that better align with our long-term strategy, expanding our capital base, or merger, acquisition, or divestiture opportunities. We analyze and evaluate potential business opportunities that we identify or are presented to us that might be a strategic fit for our investment strategy or asset allocation or otherwise maximize value for our shareholders. Pursuing such an opportunity or transaction could require us to issue additional equity or debt securities.

For further discussion of the risks inherent in our business model, please see "Liquidity and Capital Resources" within this Item 2 and in Part I, Item 3 of this Quarterly Report on Form 10-Q as well as in Item 1A, "Risk Factors" of Part I of our Annual Report on Form 10-K for the year ended December 31, 2016.

Market Conditions and Recent Activity

Market volatility remained largely subdued during the third quarter of 2017 and as a result credit spreads modestly tightened or held steady across most asset classes. As of September 30, 2017, market credit spreads in general and in sectors in which we invest were at or near their tightest levels in the last year. Credit spreads for fixed-rate Agency RMBS have lagged other sectors which we believe reflects market concerns over the announced balance sheet reduction by the Federal Reserve and in our view continues to make these securities the most attractive risk-adjusted return in the market. We also believe that the macroeconomic environment continues to be supportive for RMBS and CMBS. In particular, two major central banks (the Bank of Japan and the European Central Bank) continue to inject liquidity through large scale asset purchases supporting valuations across sectors.

Interest rates were largely unchanged during the quarter but traded in a fairly wide range generally in response to shifting economic data. As expected by the markets, the FOMC increased the target Federal Funds Rate by 0.25% in June 2017 and has now increased the target Federal Funds Rate a full 1.00% to a current targeted range of 1.00% - 1.25% since December 2015. The chart below shows the highest and lowest rates during the three months ended September 30, 2017 as well as the rates as of September 30, 2017 and June 30, 2017 for the indicated U.S. Treasury securities:

The interest rate swap curve was slightly higher during the quarter and volatility was reasonably muted. The chart below shows the highest and lowest swap rates during the three months ended September 30, 2017 as well as the swap rates as of September 30, 2017 and June 30, 2017:

In general, global fundamentals have improved; however, we continue to view the economic environment as fragile for a number of reasons, including high levels of global debt, the uncertain geopolitical environment, and the uncertain regulatory environment, including potential shifts in Federal Reserve policy that could result from leadership changes at the Federal Reserve. We believe these conditions can create an environment of intermittent volatility, and there is potential for a rapid reversal in current monetary policy in the U.S. Given this backdrop, we will continue to invest in high credit quality and highly liquid assets for the near term. We also are mindful of potential developments that could impact our view. In particular, changes in inflation or in the expectation of future inflation or performance could cause a sharp increase in volatility and changes in monetary policy.

Highlights of the Third Quarter of 2017

During the third quarter of 2017, we continued to sell lower yielding hybrid ARMs and reallocate capital into 30-year fixed-rate Agency RMBS through the purchase of specified pools and TBA securities. Given the challenging risk environment that currently exists globally, we are focusing on fixed-rate Agency RMBS because their higher liquidity gives us the ability to readjust our risk position more rapidly than other asset classes. Management believes that risk-adjusted returns on fixed-rate Agency RMBS are more favorable than other asset classes, particularly if credit spreads widen in the future. Furthermore, prepayments on fixed-rate Agency RMBS are more predictable than adjustable-rate Agency RMBS, which currently have higher risk of prepayment in the flat yield curve environment.

Comprehensive income to common shareholders of $0.27 per common share for the third quarter of 2017 was comprised of net income to common shareholders of $0.15 per common share and other comprehensive income ("OCI") of $0.12 per common share, which resulted primarily from the favorable impact of credit spread tightening on the fair value of the majority of MBS as mentioned previously. In the second quarter, comprehensive income to common shareholders was $0.05 per common share consisting of net loss to common shareholders of ($0.20) per common share and other comprehensive income ("OCI") of $0.25 per common share. Net interest income for the third quarter of 2017 declined approximately 18% compared to the second quarter of 2017 as a result of increasing short-term interest rates, a modest decline in average interest earning assets, and a decrease in prepayment penalty compensation from CMBS. The decline in net interest income was more than offset by gains

on derivative instruments (both TBAs and interest rate swaps) which increased from losses on derivative instruments incurred during the second quarter of 2017.

Core net operating income to common shareholders (a non-GAAP measure) was $0.19 per common share for the third quarter of 2017, the same as the second quarter. Drop income from TBA dollar roll transactions and lower net periodic interest costs from interest rate swaps offset higher borrowing costs and lower prepayment penalty compensation. Please see "Non-GAAP Financial Measures" at the end of this "Executive Overview" for additional important information about non-GAAP measures.

Book value per common share increased $0.08 to $7.46 as of September 30, 2017 from June 30, 2017 primarily because our investments outperformed our hedges as a result of tightening credit spreads. Economic return on book value was 3.5% for the third quarter of 2017 and 11.4% for the first nine months of 2017. Economic return on book value is calculated by dividing (i) the sum of dividends declared per common share and the change in book value per common share by (ii) beginning book value per common share.

Management Outlook

The environment remains conducive to generating net interest income from high quality investments due to low realized volatility and a benign outlook for central bank withdrawal of stimulus. We believe that fixed-rate Agency MBS continue to offer the most attractive relative return currently and will be the predominant marginal use of our capital for the foreseeable future. We expect to maintain leverage including TBA securities at cost as if settled at levels modestly higher than where they were at the end of the third quarter of 2017, but we remain concerned about sudden spikes in market volatility and may quickly reduce leverage should conditions warrant. Global central bank policies are the dominating factors for interest rates and credit spreads, and global central banks are seeking to minimize market volatility to encourage recovery in global economic growth. Should market volatility increase, our book value is likely to decline, but we would view this volatility as a potential investment opportunity given our views of expected central bank behavior. Our expectation is that our net interest spread should remain relatively flat for the fourth quarter of 2017, and that performance beyond the fourth quarter of 2017 will be highly dependent on Federal Reserve monetary policy and our hedging strategy.

Longer term we continue to believe that the outlook for our business model is very positive. Demographic trends in the U.S. are driving a significant increase in household formation, creating more demand in multifamily and single-family housing. As government participation in the housing market shrinks, there will be an increased need for private capital and expertise in the housing finance system. Global demographic aging trends are driving demand for assets that generate income. Fundamentally, this supports the assets in which we invest and also could be a source of capital for us to potentially grow our portfolio. We also intend to capitalize on opportunities for investing capital as government and regulatory policies shift while realizing that such shifts may occur over a period of several years. We will also continue seeking ways to diversify funding sources if the regulatory environment becomes more favorable, and we will also actively manage our hedge instruments to attempt to mitigate the impact on our costs of funds if the Federal Funds rate continues to increase.

Non-GAAP Financial Measures

In addition to the Company's operating results presented in accordance with GAAP, the information presented within Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Quarterly Report on Form 10-Q contains the following non-GAAP financial measures: core net operating income to common shareholders (including per common share), adjusted interest expense, adjusted net interest income, and the related metrics adjusted cost of funds and adjusted net interest spread. Management views core net operating income to common shareholders as an estimate of the net interest earnings and drop income from our investments after operating expenses and preferred stock dividends. In addition to the reconciliation set forth below, which derives core net operating income to common shareholders from GAAP net income to common shareholders as the nearest GAAP equivalent measure, core net operating income to common shareholders can also be determined by adjusting net interest income to include interest rate swap periodic interest costs, drop income on TBA securities, general and administrative expenses (GAAP), and preferred dividends. Management includes drop income in core net operating income to common shareholders and in adjusted net interest income because TBA securities are viewed by management as economically equivalent to holding and financing Agency RMBS using short-term repurchase agreements. Management also includes periodic interest costs from its interest rate swaps, which are included in "gain (loss) on derivative instruments" on the

Company's consolidated statements of comprehensive income, in adjusted net interest expense and in adjusted net interest income because interest rate swaps are used by the Company to economically hedge the Company's borrowing costs from repurchase agreements, and including periodic interest costs from interest rate swaps is a helpful indicator of the Company’s total cost of financing in addition to GAAP interest expense. Because these measures are used in the Company's internal analysis of financial and operating performance, management believes that they provide greater transparency to our investors of management's view of our economic performance. Management also believes the presentation of these measures, when analyzed in conjunction with the Company's GAAP operating results, allows investors to more effectively evaluate and compare the performance of the Company to that of its peers. Because these non-GAAP financial measures include or exclude, as applicable, certain items used to compute GAAP net income to common shareholders, GAAP net interest income, or GAAP interest expense, these non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, the Company's GAAP results as reported on its consolidated statements of comprehensive income. In addition, because not all companies use identical calculations, the Company's presentation of non-GAAP financial measures may not be comparable to other similarly-titled measures of other companies.

Schedules reconciling adjusted interest expense and adjusted net interest income to their related GAAP financial measures are provided within "Results of Operations". The following table presents a reconciliation of our GAAP net income (loss) to common shareholders to our core net operating income to common shareholders for the periods presented:

	Three Months Ended

(2) Amount represents net realized and unrealized gains and losses on derivatives and excludes net periodic interest costs related to these instruments.

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. Our accounting policies that require the most significant management estimates, judgments, or assumptions, or that management believes includes the most significant uncertainties, and are considered most critical to our results of operations or financial position relate to fair value measurements, amortization of investment premiums, and other-than-temporary impairments. Our critical accounting policies are discussed in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of

Operations” of our Annual Report on Form 10-K for the year ended December 31, 2016 under “Critical Accounting Policies”. There have been no significant changes in our critical accounting policies during the three months ended September 30, 2017.

FINANCIAL CONDITION

Throughout the nine months ended September 30, 2017, we have been deploying available capital into specified and generic fixed-rate Agency RMBS and Agency CMBS. These assets generally have longer durations and higher yields than other assets of similar credit quality which management believes offer better risk-adjusted returns in the current environment. In addition, prepayments on fixed-rate Agency RMBS are more predictable than adjustable-rate Agency RMBS, which currently have a higher risk of prepayment in the flat yield curve environment. The following charts show the composition of our investment portfolio as of September 30, 2017 compared to December 31, 2016:

(1) Includes TBA securities, which are accounted for as "derivative assets (liabilities)" on our consolidated balance sheet, at their if-settled cost basis as of the end of the period.

The following table details the activity related to our MBS portfolio during the nine months ended September 30, 2017:

	Agency CMBS			Agency RMBS						CMBS IO (2)			Non-Agency Other (3)			Total

(1) Does not include TBA securities accounted for as "derivative assets (liabilities)" on our consolidated balance sheet.

(2) Includes Agency and non-Agency issued securities.

(3) Includes non-Agency CMBS and RMBS.

We sold over 50% of our investments in adjustable-rate Agency RMBS since December 31, 2016 as we expect these assets to underperform other asset classes in the current flat yield curve environment. During the same period, we also sold the majority of our non-Agency RMBS because these investments were generally within a year of their expected maturity. We also sold approximately half of our non-Agency CMBS investments because their risk-adjusted returns were lower relative to other assets.

The following table provides a summary of the amortized cost and fair value of our investment portfolio as of the periods indicated:

	September 30, 2017				December 31, 2016
	Amortized Cost		Fair Value		Amortized Cost		Fair Value

(1) TBA securities are accounted for as "derivative assets (liabilities)" on our consolidated balance sheet at their net carrying value which represents the difference between the market value and the cost basis of the TBA contract as of the end of the period.

CMBS

Because Agency CMBS are guaranteed by the GSEs with respect to return of principal, our credit exposure is limited to any unamortized premium remaining on those securities. Non-Agency CMBS are not guaranteed and therefore our entire investment is exposed to credit losses from the underlying loans collateralizing the CMBS. The following table presents the par value, amortized cost, and weighted average months to estimated maturity of our CMBS investments as of the dates indicated by year of origination:

	September 30, 2017					December 31, 2016
($ in thousands)	Par Value		Amortized Cost		Months to Estimated Maturity (1)	Par Value		Amortized Cost		Months to Estimated Maturity (1)
Year of Origination:
2008 and prior	$	41,058	$	37,869	38	$	57,771	$	53,161	34
2009 to 2012	135,326		138,475		26	193,061		198,916		33

	$	1,343,017	$	1,351,255	97	$	1,232,053	$	1,239,203	97

(1) Months to estimated maturity is an average weighted by the amortized cost of the investment.

As of September 30, 2017, the majority of the collateral underlying our non-Agency CMBS is comprised of multifamily properties. The portion of our non-Agency CMBS collateralized with single-family rental properties were sold during the second quarter of 2017. The collateral underlying our non-Agency CMBS investments is geographically dispersed in order to mitigate exposure to any particular region of the country. The U.S. state with the largest percentage of collateral underlying our non-Agency CMBS was Maryland at 23% as of September 30, 2017 and Texas at 16.0% as of December 31, 2016.

CMBS IO

Income earned from CMBS IO is based on interest payments received on the underlying commercial mortgage loan pools. Our return on these investments may be negatively impacted by any change in scheduled cash flows such as modifications of the mortgage loans or involuntary prepayments including defaults, foreclosures, and liquidations on or of the underlying mortgage loans prior to its contractual maturity date. In order to manage our exposure to credit performance, we generally invest in senior tranches of these securities and where we have evaluated the credit profile of the underlying loan pool and can monitor credit performance. In addition, to address changes in market fundamentals and the composition of mortgage loans collateralizing an investment, we consider the year of origination of the loans underlying CMBS IO in our selection of investments. The following table presents our CMBS IO investments as of September 30, 2017 by year of origination:

	September 30, 2017					December 31, 2016
($ in thousands)	Amortized Cost		Fair Value		Remaining WAL  (1)	Amortized Cost		Fair Value		Remaining WAL  (1)
Year of Origination:

	$	717,115	$	730,467	37	$	757,892	$	754,546	42

(1) Remaining weighted average life ("WAL") represents an estimate of the number of months of interest earnings remaining for the investments by year of origination.

Approximately 67% of the collateral underlying our non-Agency CMBS IO is comprised of retail, office, and multifamily properties as of September 30, 2017, and there have been no material changes to the characteristics or distribution of collateral type underlying these securities since December 31, 2016. The collateral underlying our non-Agency CMBS IO investments is geographically dispersed in order to mitigate exposure to any particular region of the country. The U.S. state with the largest percentage of collateral underlying our non-Agency CMBS IO was California at 14% as of September 30, 2017, unchanged compared to December 31, 2016.

RMBS

In addition to purchasing specified pools of fixed-rate Agency RMBS, we also utilize TBA contracts to purchase generic pools of fixed-rate Agency RMBS. Although these instruments are accounted for as derivatives, management views TBA securities as the economic equivalent of investing in and financing generic fixed-rate Agency RMBS through the repurchase agreement market and, therefore, evaluates the economics of these transactions in its assessment of the performance of its Agency RMBS portfolio. The following table provides information on our Agency RMBS investments including TBA securities as of September 30, 2017:

	September 30, 2017
							Weighted Average Based on Par

(1) Fair value of TBA securities is the current market value of the TBA contract and represents the estimated fair value of the underlying Agency security as of the end of the period.

(2) Cost basis of TBA securities represents the forward price to be paid for the underlying Agency MBS as if settled.

(3) The net carrying value of TBA securities, which is the difference between the market value and the cost basis of the TBA securities, was $(0.1) million as of September 30, 2017 and is included on the consolidated balance sheet within "derivative liabilities".

(4) TBAs are excluded from this calculation as they do not have a defined weighted-average loan balance or age until mortgages have been assigned to the pool.

(5) Constant prepayment rate ("CPR") represents the 3-month CPR of Agency RMBS held as of date indicated. Securities with no prepayment history are excluded from this calculation.

(6) Duration is used to measure the market price volatility as interest rates change using dollar value of one basis point ("DV01") methodology.

(7) Coupon of adjustable-rate Agency RMBS represents the weighted average coupon based on amortized cost.

We did not have any investments in specified or non-specified pools of fixed-rate Agency RMBS as of December 31, 2016.

As mentioned previously, we have been reallocating capital away from adjustable-rate RMBS given the likelihood these investments will underperform in the current flat yield curve environment. We have been allowing and will continue to allow this portion of our portfolio to liquidate either on its own through payoffs or by selling when attractive bids are available. The following table provides information on our adjustable-rate RMBS by months to interest rate reset as of the dates indicated:

	September 30, 2017						December 31, 2016

Derivative Assets and Liabilities

We use interest rate swaps to hedge our earnings and book value exposure to fluctuations in interest rates. We regularly monitor and adjust our hedging portfolio in response to many factors including, but not limited to, changes in our investment portfolio, shifts in the yield curve, and our expectations with respect to the future path of interest rates and interest rate volatility.     

We also utilize TBA contracts as a means of investing in and financing fixed-rate Agency RMBS. These forward contracts are accounted for as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA contract that its settlement will result in physical delivery of the underlying Agency RMBS or the individual TBA contract will not settle in the shortest time period possible. Please refer to "RMBS" above for additional information about TBAs.

    The following graphs present the effective notional balance outstanding and net weighted average pay-fixed rate for our interest rate swaps for the periods indicated:

During the nine months endedSeptember 30, 2017, we added interest rate swaps with a combined notional of $3.0 billion at a weighted average net pay-fixed rate of 1.80% and we terminated $1.1 billion in interest rate swaps with a weighted average net pay-fixed rate of 0.69%. Additionally, we had $0.2 million of interest rate swaps mature during the nine months endedSeptember 30, 2017 with a weighted average net pay-fixed rate 0.92%. Our adjustments to the hedging portfolio were made in response to many market factors including, but not limited to, changes in our investment allocations, investing in TBA securities, shifts in the yield curve, and expectations with respect to the future path of interest rates and interest rate volatility, which is discussed further in "Quantitative and Qualitative Disclosures about Market Risk" in Item 3 of this Quarterly Report on Form 10-Q.

The following table summarizes the activity related to our interest rate swaps during the nine months endedSeptember 30, 2017:

	Nine Months Ended

(2) As of January 2017 margin requirements from fluctuations in fair value of the Company's cleared interest rate swaps are settled daily with the Chicago Mercantile Exchange ("CME").

Repurchase Agreements

The majority of our repurchase agreement borrowings are collateralized with Agency MBS which have historically had lower liquidity risk than non-Agency MBS. The following table presents the amount pledged and leverage against the fair value of our non-Agency MBS investments by credit rating as of September 30, 2017 and December 31, 2016:

Shareholder's Equity

Shareholder's equity increased approximately 12% during the first nine months of 2017 primarily due to an increase of $38.5 million in the fair value of MBS, which is recorded in accumulated other comprehensive income. The increase in the fair value of MBS since December 31, 2016 resulted primarily from credit spread tightening. The following table provides the accumulated unrealized holding gains (losses) by type of MBS and the remaining balance of de-designated cash flow hedges as of the periods indicated:

($ in thousands)	September 30, 2017			December 31, 2016
Agency CMBS	$	(7,436	)	$	(22,295	)
Non-Agency CMBS	2,877			5,467

Non-Agency RMBS	29			14
De-designated cash flow hedges	450			670
Accumulated other comprehensive income (loss)	$	5,886		$	(32,609	)

During the nine months endedSeptember 30, 2017, we issued 1,093,164 shares of Series B Preferred Stock under our preferred stock ATM program at a discount of approximately 5% to the liquidation value of $25.00 per share. Cash proceeds were $25.9 million, net of 2% broker commissions and other fees. On March 31, 2017, the Company entered into an amended and restated equity distribution agreement pursuant to which the Company may offer and sell up to 7,416,520 shares of common stock of the Company from time to time through its sales agent in at-the-market ("ATM") offerings. We issued 2,027,857 shares of common stock pursuant to this agreement during the nine months endedSeptember 30, 2017 at a discount of approximately

5% to book value of $7.46 per common share at September 30, 2017. We are using the cash proceeds from these capital raises in combination with repurchase agreement borrowings to purchase additional interest earning assets for our investment portfolio.

RESULTS OF OPERATIONS

The discussions below provide information on items on our consolidated statements of comprehensive income. These discussions include both GAAP and non-GAAP financial measures which management utilizes in its internal analysis of financial and operating performance. Please read the section "Non-GAAP Financial Measures" at the end of "Executive Overview" in Part 1, Item 2 of this Quarterly Report on Form 10-Q for additional important information about these measures.

Interest Income and Effective Yields on MBS

Interest income includes gross interest earned from the coupon rate on the securities, premium amortization and discount accretion, and other interest income resulting from prepayment penalty income or other yield maintenance items on CMBS and CMBS IO securities. Effective yields are calculated by dividing the sum of gross interest income and scheduled premium amortization/discount accretion (both of which are annualized for any reporting period less than 12 months) and prepayment compensation and premium amortization/discount accretion adjustments (collectively, "prepayment adjustments"), which are not annualized, by the average balance of investments outstanding during the reporting period. The following table presents details on average balances, interest income, and effective yields of MBS for the periods indicated:

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

Interest income and effective yields on our total MBS portfolio for the three and nine months endedSeptember 30, 2017 increased due to higher prepayment penalty income from CMBS and CMBS IO and lower premium amortization adjustments on RMBS compared to the three and nine months endedSeptember 30, 2016. Interest income and effective yields on MBS also increased overall as a result of our shift in investment strategy to higher yielding fixed-rate securities over the past twelve months. The following tables present the estimated impact of changes in average balances, yields, and prepayment adjustments on interest income by type of MBS for the periods indicated:

	Three Months Ended

(1) Prepayment adjustments represent effective interest amortization adjustments related to changes in actual and projected prepayment speeds for RMBS and prepayment compensation, net of amortization for CMBS and CMBS IO.

Interest income from CMBS increased for the three and nine months endedSeptember 30, 2017 compared to the three and nine months endedSeptember 30, 2016 due to a higher average balance and higher prepayment penalty income while the effective yield earned on our CMBS portfolio was lower for three and nine months endedSeptember 30, 2017 due primarily to lower average coupons on our current CMBS portfolio versus the same periods in the prior year.

Interest income and effective yield for CMBS IO for the three and nine months endedSeptember 30, 2017 increased compared to the three and nine months endedSeptember 30, 2016 due to an increase in prepayment penalty income for the three and nine months endedSeptember 30, 2017 versus the same periods in 2016.

Interest income declined on RMBS for the three and nine months endedSeptember 30, 2017 primarily due to a decrease in the average balance of approximately (38)% and (32)% for the three and nine months endedSeptember 30, 2017, respectively, compared to the same periods in 2016. The increase of 33 basis points in the effective yield on RMBS for the three months ended September 30, 2017 compared to the same period in 2016 is due to the addition of $544.1 million in specified pools of 30-year fixed-rate Agency RMBS during the third quarter of 2017. Because these fixed-rate securities are newer issues, they have higher coupons than the adjustable-rate RMBS we have sold since September 30, 2016. Premium amortization was lower for the three and nine months endedSeptember 30, 2017 as a result of the sales of adjustable-rate RMBS. The rate at which we amortize the premiums on adjustable-rate Agency RMBS is impacted by actual and forecasted prepayments, which is measured by the constant prepayment rate ("CPR"). The following graph shows our actual 3 month average CPRs for our adjustable-rate Agency RMBS for the periods indicated:

Premium amortization on our fixed-rate Agency RMBS is adjusted when actual prepayments are received. The CPR for our fixed-rate Agency RMBS was 1.3% for the third quarter of 2017. We do not forecast prepayments on our fixed-rate Agency RMBS.         

Interest Expense and Cost of Funds

The following table summarizes the components of interest expense as well as average balances and cost of funds for the periods indicated:

(1) Amount recorded in accordance with GAAP related to accretion of the balance remaining in accumulated other comprehensive income as a result of our discontinuation of cash flow hedge accounting effective June 30, 2013.

(2) Cost of funds is calculated by dividing annualized interest expense by the total average balance of borrowings outstanding during the period.

The following table presents the estimated impact of the change in average balances and borrowing rates of secured borrowings and other differences in interest expense for the comparative periods presented:

($ in thousands)	Three Months Ended September 30, 2017 vs. September 30, 2016			Nine Months Ended September 30, 2017 vs. September 30, 2016
Change in borrowing rates on repurchase agreements and FHLB advances	$	4,169		$	8,927
Change in average balance of repurchase agreements and FHLB advances	(402		)	(1,216		)
Decrease (increase) in accretion of de-designated cash flow hedges	51			(68		)
Decrease in non-recourse collateralized financing and other interest expense	3			1
Total change in interest expense	$	3,821		$	7,644

Increases in interest expense for the three and nine months endedSeptember 30, 2017 compared to the same periods in 2016 were due to higher borrowing rates on our repurchase agreements. Our borrowing rates are based primarily on one-month LIBOR which has increased approximately 70 basis points since September 30, 2016.

Adjusted Interest Expense

Because we use derivative instruments as economic hedges of our interest rate risk exposure, management considers net periodic interest costs from derivative instruments to be an additional cost of financing investments. As such, management uses the non-GAAP financial measure "adjusted interest expense" which includes the net periodic interest costs of our effective derivative instruments excluded from GAAP interest expense. Please read the section "Non-GAAP Financial Measures" at the end of "Executive Overview" in Part 1, Item 2 of this Quarterly Report on Form 10-Q for additional information. The table below presents the reconciliation of GAAP interest expense to our adjusted interest expense for the periods indicated:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
($ in thousands)	2017		2016		2017		2016
Interest expense	$	9,889	$	6,068	$	26,122	$	18,478
Add: net periodic interest costs of derivative instruments (1)	1,131		155		3,099		2,321
Less: de-designated hedge accretion (2)	48		99		220		152
Adjusted interest expense	$	11,068	$	6,322	$	29,441	$	20,951

1) Amounts represent net periodic interest costs on effective interest rate swaps outstanding during the period and exclude termination costs and changes in fair value.

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

Of the $1.1 million and $3.1 million in net periodic interest costs incurred during the three and nine months endedSeptember 30, 2017, respectively, $0.8 million and $1.3 million, respectively, relates to interest rate swaps we added to our hedging portfolio in order to mitigate the potential impact of changing interest rates on our TBA securities.

Net Interest Income and Net Interest Spread

The tables below present net interest income and net interest spread for our interest-earning assets and interest-bearing liabilities 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) Average balances are calculated as a simple average of the daily borrowings outstanding for both repurchase agreement and non-recourse collateralized financing.

Net interest income and net interest spread declined due to higher borrowing costs during the three and nine months ended September 30, 2017 compared to the respective periods in 2016. Higher borrowings costs were partially mitigated by an increase in interest income for the three and nine months ended September 30, 2017 compared to the respective periods in 2016, which resulted from replacing lower yielding adjustable-rate RMBS with higher yielding fixed-rate MBS during the past twelve months. Please refer to "Interest Income and Effective Yields" and "Interest Expense and Cost of Funds" for additional information.

Adjusted Net Interest Income

Drop income from TBA securities and net periodic interest costs from interest rate swaps effective during the period are included in "gain (loss) on derivatives instruments, net" on the Company's consolidated statements of comprehensive income. Drop income is the difference in price between the near settling TBA contract and the price for the same contract with a later settlement date. Management believes drop income represents the economic equivalent of net interest income (interest income less implied financing cost) on the underlying Agency security from trade date to settlement date. Management also views net periodic interest costs from interest rate swaps used to hedge interest rate risk as an additional cost of using repurchase agreements

to finance its investments. As such, management includes drop income from TBA securities and net periodic interest costs from interest rate swaps in a non-GAAP financial measure "adjusted net interest income". The following table reconciles adjusted net interest income to GAAP net interest income for the periods indicated:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
($ in thousands)	2017			2016			2017			2016

Adjusted net interest income	$	15,937		$	14,813		$	46,190		$	48,089

(1) Amounts represent net periodic interest costs on effective interest rate swaps outstanding during the period and exclude termination costs and changes in fair value.

(2) Amount recorded in accordance with GAAP related to accretion of the balance remaining in accumulated other comprehensive income as a result of our discontinuation of cash flow hedge accounting effective June 30, 2013.

Loss on Derivative Instruments, Net

(1) Changes in fair value for interest rate swaps and Eurodollar futures include unrealized gains (losses) from current and forward starting derivative instruments and realized gains (losses) from terminated derivative instruments.

(2) Change in fair value for TBA securities includes unrealized gains (losses) from open TBA contracts and realized gains (losses) on terminated positions.

Changes in the fair value of interest rate swaps and Eurodollar futures and net periodic interest costs are impacted by changing market interest rates in any given period. In addition, because we continually monitor our hedge positioning and make changes based on our investment portfolio and related financings, management's view of the future path of interest rates, and where

we believe hedges will be most effective in relation to our capital allocation and interest rate risk, gains and losses on derivative instruments will also fluctuate based on the notional amount, maturity, and interest rate of the derivative instruments held during the period. Because of the changes made to our hedging portfolio from one reporting period to the next, results of any given reporting period are generally not comparable to results of another.

During the three months ended September 30, 2017, the fair value of our interest rate swaps increased $0.4 million as a result of higher swap rates (as shown in the Swap Rate Range graph under “Market Conditions and Recent Activity” within "Executive Overview"). Because we are "short" interest rate swaps (i.e., we pay a fixed rate of interest and receive a floating rate of interest based primarily on 3 month LIBOR), increases in swap rates result in increases in the fair value of the interest rate swaps. During the quarter, we also terminated interest rate swaps on which we paid net proceeds of $0.7 million.

For the nine months ended September 30. 2017, the fair value of interest rate swaps declined $15.0 million also as a result of lower swap rates during that period, specifically on the long end of the swap curve. Declines in fair value for the nine months ended September 30, 2016 were largely unfavorable as compared to the same periods in 2017 as a result of a larger declines in rates along the entire swap curve as well as changes in the composition of the hedging portfolio.

Net periodic interest costs for the three and nine months ended September 30, 2017 were higher than the same periods in 2016 due to a larger average notional balance of effective interest rate swaps outstanding at higher weighted-average pay-fixed rates as shown in the following table for the periods indicated:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
($ in thousands)	2017			2016			2017			2016
Average notional balance	$	2,668,478		$	305,000		$	2,011,355		$	549,617
Weighted average net pay-fixed rate	1.37		%	0.64		%	1.30		%	1.06		%

As mentioned previously, we execute TBA dollar roll transactions which effectively delay the settlement of a forward purchase of an Agency RMBS by entering into an offsetting short position (referred to as a "pair off"), net settling the paired-off positions in cash, and simultaneously entering a similar TBA contract for a later settlement date. TBA securities purchased for a forward settlement month are generally priced at a discount relative to TBA securities sold for settlement in the current month. This discount, often referred to as “drop income” is the economic equivalent of net interest income on the underlying Agency securities over the roll period (interest income less implied financing cost). The average if-settled cost basis of the TBA securities, which represents the basis on which we earned drop income during the three and nine months ended September 30, 2017, and the related drop income are presented in the following table:

	Three Months Ended				Nine Months Ended
	September 30, 2017				September 30, 2017
($ in thousands)	Average Cost Basis		Drop Income (1)		Average Cost Basis		Drop Income (1)
TBA securities:

Total TBA securities	$	797,484	$	3,902	$	356,837	$	5,253

(1) Drop income is recognized in "gain (loss) on derivatives, net" on our consolidated statements of comprehensive income.

Loss on Sale of Investments, Net

Sales of our investments occur in the ordinary course of business as we manage our risk, capital and liquidity profiles, and as we reallocate capital to various investments. As mentioned previously, we have been reallocating our capital from adjustable-rate Agency RMBS to generic and specified pools of fixed-rate Agency RMBS, which we believe to be more liquid and less vulnerable to loss in book value from credit spread widening versus other investments in the current macroeconomic environment. The following tables provide information related to our loss on sale of investments, net for the periods indicated:

General and Administrative Expenses

Compensation and benefits expense was $0.3 million and $0.5 million higher for the three and nine months endedSeptember 30, 2017 compared to the same periods in 2016 primarily due to the timing of bonus expense accrual and the related payments. Other general and administrative expenses were $0.5 million higher for the nine months ended September 30, 2017 compared to the same period in 2016 due primarily to higher legal expenses related to a lawsuit filed in 2017 which is discussed in more detail in Item 1 of Part II of this Quarterly Report on Form 10-Q.

Other Comprehensive Income

The following table provides detail on the changes in fair value by type of MBS which are recorded as unrealized gains (losses) in other comprehensive income on our consolidated statements of operations for the periods indicated:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
($ in thousands)	2017			2016			2017			2016

Unrealized gain on available-for-sale investments	$	6,192		$	769		$	38,715		$	65,498

Credit spreads tightened during the three months ended September 30, 2017 and September 30, 2016 which increased the fair value of MBS in our portfolio during those periods and more than offset the impact of slightly higher interest rates during those same periods. The increase in fair value of MBS of $38.7 million during the nine months ended September 30, 2017 was primarily due to credit spread tightening during the period. The increase in fair value of MBS of $65.5 million during the nine

months ended September 30, 2016 was primarily due to declining interest rates during the period, which favorably impacted the longer duration investments such as Agency CMBS.

LIQUIDITY AND CAPITAL RESOURCES

 Our primary sources of liquidity include borrowings under repurchase arrangements and monthly principal and interest payments we receive on our investments. Additional sources may also include proceeds from the sale of investments, equity offerings, and payments received from counterparties from interest rate swap agreements. We use our liquidity to purchase investments and to pay our operating expenses and dividends on our common and preferred stock. We also use our liquidity to post initial margin and variation margin on our repurchase agreements and derivative transactions, including TBA contracts, when required under the terms of the related agreements. We may also use liquidity to repurchase shares of our stock.

Our liquid assets fluctuate based on our investment activities, our financing and capital raising activities, and changes in the fair value of our MBS and derivative instruments. We seek to maintain sufficient liquidity to support our operations and to meet our anticipated liquidity demands, including potential margin calls from lenders (as discussed further below). We measure, manage, and forecast our liquidity on a daily basis. Our available liquid assets include unrestricted cash and cash equivalents, unencumbered Agency MBS, and certain unencumbered non-Agency MBS that can be pledged as collateral for margin calls or converted reasonably quickly into cash. As of September 30, 2017, our available liquid assets were $239.2 million, which consisted of unrestricted cash and cash equivalents of $117.7 million and unencumbered Agency MBS of $121.5 million, compared to $138.1 million as of December 31, 2016. Unencumbered Agency MBS excludes purchases and sales of MBS pending settlement. The increase in available liquid assets since December 31, 2016 is primarily due to our shift in investment mix.

We perform sensitivity analysis on our liquidity based on changes in the fair value of our investments due to changes in interest rates, credit spreads, lender haircuts, and prepayment speeds as well as changes in the fair value of our derivative instruments due to changes in interest rates. In performing this analysis we will also consider the current state of the fixed income markets and the repurchase agreement markets in order to determine if market forces such as supply-demand imbalances or structural changes to these markets could change the liquidity of MBS or the availability of financing. The objective of our analysis is to assess the adequacy of our liquidity to withstand potential adverse events. We may change our leverage targets based on market conditions and our perceptions of the liquidity of our investments.

We 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 ratio. 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 8 times our shareholders' equity. Including our TBA position at cost (if settled), which was $683.8 million as of September 30, 2017, our leverage was 6.3 times shareholders' equity. The financing for TBA securities is implied through our use of TBA dollar roll transactions whereby we enter into an offsetting TBA contract and net settle the paired off position in cash. It is possible under certain market conditions that it may be uneconomical for us to roll our TBA contracts into future months, which may result in us having to take physical delivery of the underlying securities. Because under those circumstances we would have to fund our total purchase commitment with cash or other financing sources, which may impact our liquidity position, management includes our TBA position at cost (if settled) in evaluating the Company's leverage.

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

Repurchase Agreements

 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 September 30, 2017, we had repurchase agreement borrowings outstanding with 18 of our 34 available repurchase agreement counterparties at a weighted average borrowing rate of 1.51% compared to 1.03% as of December 31, 2016. Our repurchase agreement borrowings generally carry a rate of interest based on a spread to an index such as LIBOR.

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

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

	September 30, 2017		June 30, 2017		March 31, 2017		December 31, 2016		September 30, 2016
Agency CMBS and RMBS	5.0	%	5.0	%	5.0	%	5.0	%	5.1	%
Non-Agency CMBS and RMBS	15.0	%	18.0	%	15.8	%	16.3	%	17.0	%
CMBS IO	15.0	%	15.0	%	15.3	%	15.4	%	15.4	%

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 counterparty in excess of the borrowed amount outstanding. This equity at risk represents the potential loss to the Company if the counterparty is unable or unwilling to return collateral securing the repurchase agreement borrowing at its maturity. The following tables present the counterparties with whom we had greater than 5% of our equity at risk as of September 30, 2017 and December 31, 2016:

	September 30, 2017
($ in thousands)	Amount Outstanding		Equity at Risk
Well Fargo Bank, N.A. and affiliates	$	349,965	$	57,992
JP Morgan Securities, LLC	270,883		30,803
	$	620,848	$	88,795

JP Morgan Securities, LLC	212,921		35,658
	$	1,152,475	$	136,469

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 September 30, 2017 and December 31, 2016:

	September 30, 2017				December 31, 2016
($ in thousands)	Amount Outstanding		Market Value of Collateral Pledged		Amount Outstanding		Market Value of Collateral Pledged
North America	$	1,685,493	$	1,840,749	$	2,105,337	$	2,309,391
Asia	521,832		548,717		421,991		443,098
Europe	311,905		328,537		371,624		397,351
	$	2,519,230	$	2,718,003	$	2,898,952	$	3,149,840

Certain of 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.

Derivative Instruments

Our derivative instruments may require us to post initial margin at inception and variation margin based on subsequent changes in the fair value of the derivatives. The collateral posted as margin by us is typically in the form of cash or Agency MBS. Generally, as interest rates decline due to market changes, we will be required to post collateral with counterparties on our pay-fixed derivative instruments and receive collateral from our counterparties on our receive-fixed derivative instruments, and vice versa as interest rates increase. As of September 30, 2017, we had cash of $44.0 million posted as initial margin under these agreements.

As of September 30, 2017, approximately $160 million of the Company's interest rate swaps were entered into under bilateral agreements which contain cross-default provisions with other agreements between the parties. In addition, these bilateral agreements contain financial and operational covenants similar to those contained in our repurchase agreements, as described above. Currently, we do not believe we are subject to any covenants that materially restrict our hedging flexibility.

Our TBA contracts are subject to master securities forward transaction agreements published by the Securities Industry and Financial Markets Association as well as supplemental terms and conditions with each counterparty. Under the terms of these agreements, we may be required to pledge collateral to our counterparty when initiated or in the event the fair value of our TBA contracts declines and such counterparty demands collateral through a margin call. Declines in the fair value of TBA contracts are generally related to such factors as rising interest rates, increases in expected prepayment speeds, or widening spreads. Our TBA contracts generally provide that valuations for our TBA contracts and any pledged collateral are to be obtained from a generally recognized source agreed to by both parties. However, in certain circumstances, our counterparties have the sole discretion to determine the value of the TBA contract and any pledged collateral. In such instances, our counterparties are required to act in

good faith in making determinations of value. In the event of a margin call, we must generally provide additional collateral on the same business day.

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). 

We have a net operating tax loss ("NOL") carryforward that we could use to offset our REIT taxable income distribution requirement. This NOL carryforward had an estimated balance of approximately $89.8 million as of September 30, 2017. We also have deferred tax hedge losses on terminated derivative instruments, which will be recognized over the original periods being hedged by those terminated derivatives. These losses have already been recognized in our GAAP earnings but will reduce taxable income over the next ten years as noted in the following table:

($ in thousands)	Tax Hedge Loss Deduction
2017	$	21,542
2018	21,175
2019	16,937
2020 - 2026	12,383
	$	72,037

If any of the deferred tax hedge losses for the years noted in the table above result in dividend distributions to our shareholders in excess of REIT taxable income, the excess dividends distributed will be considered a return of capital to the shareholder. As of September 30, 2017, we estimated that approximately 75% of our common stock dividends declared during the nine months endedSeptember 30, 2017 will represent a return of capital to shareholders and not a distribution of REIT taxable income, principally as a result of the amount of the tax hedge loss deduction.

Contractual Obligations

The following table summarizes our contractual obligations by payment due date as of September 30, 2017:

($ in thousands)	Payments due by period
Contractual Obligations:	Total		< 1 year		1-3 years		3-5 years		> 5 years
Repurchase agreements (1)	$	2,557,279	$	2,557,279	$	—	$	—	$	—
Non-recourse collateralized financing (2)	5,786		1,669		2,199		1,207		711
Operating lease obligations	544		214		330		—		—
Total	$	2,563,609	$	2,559,162	$	2,529	$	1,207	$	711

(1) Includes estimated interest payments calculated using interest rates in effect as of September 30, 2017.

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

Other Matters

As of September 30, 2017, we do not believe that any off-balance sheet arrangements exist that are reasonably likely to have a material effect on our current or future financial condition, results of operations, or liquidity other than as discussed above. In addition, we do not have any material commitments for capital expenditures and have not obtained any commitments for funds to fulfill any capital obligations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the exposure to losses resulting from changes in market factors. Our business strategy exposes us to a variety of market risks, including interest rate, spread, prepayment, reinvestment, credit, and liquidity risks. These risks can and do cause fluctuations in our comprehensive income and book value as discussed below.

Interest Rate Risk

Investing in interest-rate sensitive investments such as MBS and TBA securities subjects us to interest rate risk. Interest rate risk results from the mismatch between the duration of our assets versus the duration of our liabilities and hedges. With respect to MBS, mismatch in duration is usually the result of interest-rate reset or maturity dates and differing cash flow profiles of our assets versus our liabilities. Borrowing costs on our liabilities are generally based on prevailing short-term market rates and reset more frequently than interest rates on our assets. Changes in interest rates and changes in the forward curve also impact the market value of our investment portfolio and our derivative instruments (including TBA securities and interest rate swaps).

The measures of an instrument's price sensitivity to interest rate fluctuations are its duration and convexity. Duration measures the percentage change in projected market value of our investments and derivative instruments given a change in interest rates. The duration of our RMBS and TBA securities tend to increase when interest rates rise and decrease when interest rates fall, which is commonly referred to as negative convexity. This occurs because prepayments of the mortgage loans underlying the RMBS tend to decline when interest rates rise (which extends the life of the security) and increase when interest rates fall (which shortens the life of the security). The fair value of TBA securities react similarly to RMBS to changes in interest rates as they are based on an underlying generic pool of fixed-rate RMBS securities. CMBS and CMBS IO, however, generally have little convexity because the mortgage loans underlying the securities contain some form of prepayment protection provision (such as prepayment lock-outs) or prepayment compensation provisions (such as yield maintenance or prepayment penalties) which create an economic disincentive for the loans to prepay.

We attempt to manage our exposure to changes in interest rates that results from the duration mismatch between our assets and liabilities by entering into interest rate swaps to hedge this risk. We manage interest rate risk within tolerances set by our Board of Directors. Our portfolio duration changes based on the composition of our investment portfolio and our hedge positions as well as market factors. We calculate our portfolio duration based on model projected cash flows, and such calculated duration can be an imprecise measure of actual interest rate risk. In the case of Agency RMBS and TBA securities, the primary input to the calculated duration is the anticipated prepayment speed of the underlying mortgage loans, which is sensitive to future interest rates and borrowers' behavior. Estimates of prepayment speeds can vary significantly by investor for the same security and therefore estimates of security and portfolio duration can vary significantly.

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 our portfolio, our hedging strategy, the effectiveness of our hedging instruments as well as the magnitude and the duration of the increase in interest rates. In addition, our adjustable-rate Agency RMBS reset based on one-year LIBOR and have limits or caps on the initial, aggregate, or periodic amount that an interest rate may reset while our liabilities do not have interest rate reset caps. As of September 30, 2017, we had a positive net duration gap in our investment portfolio, which means our liabilities mature or reset sooner than our investments, and we had not fully hedged this difference. Therefore, increases in interest rates, particularly rapid increases, will negatively impact the market value of our investments, thereby reducing our book value. In addition to the information set forth in the tables below, see "Spread Risk" below for further discussion of the risks to the market value of our investments. For further discussion of the reset features of our hybrid ARMs, please refer to "Financial Condition-RMBS" within Part I, Item 2 of this Quarterly Report on Form 10-Q.

The table below shows the projected sensitivity of our net interest income and net periodic interest costs on our interest rate swaps; the projected sensitivity of the market value of our investments and derivative instruments (including TBA securities); and the percentage change in shareholders' equity as they existed as of the periods indicated 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 September 30, 2017, the only declining rate scenario that we present is a downward shift of 50 basis points.

Changes in types of our investments, the returns earned on these 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.

	September 30, 2017			December 31, 2016
	Percentage Change in			Percentage Change in
Parallel Shift in Interest Rates	Market Value of Investments (1)	Shareholders' Equity	Net Interest Income and Net Periodic Interest Costs (2)	Market Value of Investments (1)	Shareholders' Equity	Net Interest Income and Net Periodic Interest Costs (2)
+100	(1.3)%	(9.1)%	10.3%	(0.6)%	(4.4)%	(42.4)%
+50	(0.5)%	(3.7)%	5.6%	(0.3)%	(1.9)%	(20.7)%
-50	0.3%	2.1%	(7.2)%	0.2%	1.2%	18.7%

(1) Includes changes in market value of our investments and derivative instruments, including TBA securities, 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.

(2) Includes changes in net interest income as well as net periodic interest costs on our interest rate swaps recorded in "gain (loss) on derivatives instruments, net".

The projected impact on interest related earnings in an increasing interest rate environment changed from a projected decline as of December 31, 2016 to a projected increase as of September 30, 2017 because we made adjustments to our hedging portfolio during the nine months ended September 30, 2017. When the yield curve flattened during the second quarter of 2017, we entered into approximately $1.0 billion of interest rate swaps in order to "lock-in" our financing costs over the near term in an attempt to avoid potential volatility in our net interest earnings. We also entered into additional interest rate swaps to hedge the interest rate risk related to our TBA securities we began investing in during the second quarter of 2017.

Management also considers changes in the shape of the interest rate curves in assessing and managing portfolio interest rate risk. Often interest rates do not move in a parallel fashion from quarter to quarter. The table below shows the percentage change in projected market value of our investment portfolio net of derivative instruments for instantaneous changes in the shape of the U.S. Treasury ("UST") curve (with similar changes to the interest rate swap curves) as of the periods indicated:

		September 30, 2017		December 31, 2016
Basis Point Change in		Percentage Change in
2-year UST	10-year UST	Market Value of Investments (1)	Shareholders' Equity	Market Value of Investments (1)	Shareholders' Equity
+25	+50	(0.5)%	(3.6)%	0.1%	0.5%
+25	+0	(0.1)%	(0.6)%	(0.4)%	(2.5)%
+50	+25	(0.3)%	(2.3)%	(0.5)%	(3.2)%
+50	+100	(1.2)%	(8.1)%	0.1%	0.4%
-10	-50	(0.2)%	1.5%	(0.3)%	(2.3)%

(1) Includes changes in market value of our investments and derivative instruments, including TBA securities, 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.

Spread Risk

Spread risk is the risk of loss from an increase in the market spread between the yield on an investment versus its benchmark index. Changes in market spreads represent the market's valuation of the perceived riskiness of an asset relative to risk-free rates, and widening spreads reduce the market value of our investments as market participants require additional yield to hold riskier assets. Market spreads could change based on macroeconomic or systemic factors as well as the factors specific to a particular security such as prepayment performance or credit performance. Other factors that could impact credit spreads include technical issues such as supply and demand for a particular type of security or FOMC monetary policy. Likewise, most of our investments are fixed-rate or reset in rate over a period of time, and as interest rates rise, we would expect the market value of these investments to decrease.

Fluctuations in spreads typically vary based on the type of investment. Sensitivity to changes in market spreads is derived from models that are dependent on various assumptions, and actual changes in market value in response to changes in market spreads could differ materially from the projected sensitivity if actual conditions differ from these assumptions.

The table below is an estimate of the percentage change in projected market value of our investments (including TBA securities) given the indicated change in market spreads as of the periods indicated:

Basis Point Change in Market Spreads	Percentage Change in Projected Market Value of Investments
	September 30, 2017	December 31, 2016
+50	(2.6)%	(2.2)%
+25	(1.3)%	(1.1)%
-25	1.3%	1.1%
-50	2.6%	2.3%

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 are amortized as a reduction in interest income using the effective yield method under GAAP. 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.

Loans underlying our CMBS and CMBS IO securities typically have some form of prepayment protection provisions (such as prepayment lock-outs) or prepayment compensation provisions (such as yield maintenance or prepayment penalties). Yield maintenance and prepayment penalty requirements are intended to create an economic disincentive for the loans to prepay; however, the amount of the prepayment penalty required to be paid may decline over time, and as loans age, interest rates decline, or market values of collateral supporting the loans increase, prepayment penalties may lessen as an economic disincentive to the borrower. Generally, our experience has been that prepayment lock-out and yield maintenance provisions result in stable prepayment performance from period to period. There are no prepayment protections, however, if the loan defaults and is partially or wholly repaid earlier as a result of loss mitigation actions taken by the underlying loan servicer. Historically, we have experienced low default rates on loans underlying CMBS and CMBS IO.

Because CMBS IO consist of rights to interest on the underlying commercial mortgage loan pools and do not have rights to principal payments on the underlying loans, prepayment risk on these securities would be particularly acute without these prepayment protection provisions. CMBS IO prepayment protection and compensation provisions vary by issuer of the security (i.e. Freddie Mac, Fannie Mae, Ginnie Mae, or non-Agency). The majority of our Agency CMBS IO are issued by Freddie Mac and these securities 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. Non-Agency CMBS IO generally have prepayment protection in the form of prepayment lock-outs and defeasance provisions. The following table details the fair value of our CMBS IO portfolio by issuer as of the end of the periods indicated:

($ in thousands)	September 30, 2017		December 31, 2016
Fannie Mae	$	11,200	$	18,957
Freddie Mac	390,608		392,941
Non-Agency CMBS IO	328,659		342,648
	$	730,467	$	754,546

Prepayments on the loans underlying our RMBS generally accelerate in a declining interest rate environment, as the loans age, and, with respect to ARMS, as the loans near their respective interest rate reset dates, particularly the initial reset date, or if expectations are that interest rates will rise in the future. Our prepayment models anticipate an acceleration of prepayments in these events. To the extent the actual prepayments exceed our modeled prepayments, or, with respect to adjustable-rate RMBS, if we change our future prepayment expectations, we will record adjustments to our premium amortization which may negatively impact our net interest income. In addition, changes in market expectations of prepayments 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 to reset ("MTR") or until maturity in the case of fixed-rate securities as of the end of the past four quarters:

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, when we invest in RMBS at a premium to the security's par value, we tend to favor securities in which we believe the underlying borrowers have some disincentive to refinance as a result of the size of each loan's principal balance, credit characteristics of the borrower, or geographic location of the property, among other factors.

We are also subject to reinvestment risk as a result of the prepayment, repayment and sales of our investments. In order to maintain our investment portfolio size and our earnings, we need to reinvest capital received from these events into new interest-earning assets or TBA securities. If we are unable to find suitable reinvestment opportunities or if yields on assets in which we reinvest are lower than yields on existing assets, our results and cash flows could be negatively impacted. In addition, based on market conditions, our leverage, and our liquidity profile, we may decide to not reinvest the cash flows we receive from our investment portfolio even when attractive reinvestment opportunities are available, or we may decide to reinvest in assets with lower yield but greater liquidity. If we retain rather than reinvest capital or if we invest it in lower yielding assets for liquidity reasons, the size of our investment portfolio and the amount of income generated by our investment portfolio will likely decline.

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. Agency RMBS and Agency CMBS 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. Since Agency CMBS IO represent the right to excess interest and not principal on the underlying loans, these securities are exposed to the loss of investment basis in the event a loan collateralizing the security liquidates without paying yield maintenance or prepayment penalty, which typically occurs when an involuntarily liquidating loan repays all or a portion of its related principal balance.

We are exposed to credit risk on our non-Agency securities and we attempt to mitigate our credit risk through asset selection and by purchasing higher quality non-Agency MBS. Our non-Agency MBS are typically investment grade rated securities which we believe will have strong credit performance. We do not currently seek to purchase heavily discounted, credit sensitive MBS. The majority of our non-Agency securities are CMBS and CMBS IO and 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 generally are more negatively impacted by liquidations of loans in the underlying loan pool. Please refer to "Financial Condition-Repurchase Agreements" within Item 2 of this Quarterly Report on Form 10-Q for information regarding the credit ratings on our non-Agency MBS.

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 for longer-term assets, thereby creating a mismatch between the maturities of the asset and 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, declines in the market value of our investments pledged as collateral for repurchase agreement borrowings may result in counterparties initiating margin calls for additional collateral .

Our use of TBA dollar roll transactions as a means of investing in and financing Agency RMBS also exposes us to liquidity risk in the event that we are unable to roll or terminate our TBA dollar roll transactions prior to their settlement date. If we are unable to roll or terminate our TBA dollar roll transactions, we could be required to take physical delivery of the underlying securities and settle our obligations for cash, which could negatively impact our liquidity position or force us to sell assets under adverse conditions if financing is not available to us on acceptable terms.

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

ITEM 4. CONTROLS AND PROCEDURES

Disclosure controls and procedures.

Our management evaluated, with the participation of our Principal Executive Officer and Principal Financial Officer, the effectiveness of our disclosure controls and procedures, as defined in Exchange Act Rule 13a-15(e), as of the end of the period covered by this report. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2017 to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Principal Executive Officer and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting.

Our management is also responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f). There were no changes in our internal control over financial reporting during the three months ended September 30, 2017 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Organization and Summary of Significant Accounting Policies

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 specified pools of Agency and non-Agency mortgage-backed securities (“MBS”) consisting of residential MBS (“RMBS”), commercial MBS (“CMBS”) and CMBS interest-only ("IO") securities 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"). We also invest in other types of mortgage-related securities, such as to-be-announced (“TBA”) forward contracts for the purchase or sale of generic (also referred to as "non-specified") pools of Agency MBS.

Basis of Presentation

The accompanying unaudited consolidated financial statements of Dynex Capital, Inc. and its subsidiaries (together, “Dynex” or, as appropriate, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10, Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all significant adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the consolidated financial statements have been included. Operating results for the three months endedSeptember 30, 2017 are not necessarily indicative of the results that may be expected for any other interim periods or for the entire year ending December 31, 2017. The unaudited consolidated financial statements included herein should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC.

Consolidation

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

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, amortization of premiums and discounts, fair value measurements of its investments, and other-than-temporary impairments. 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 ("NOL") 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 capital gains that is distributed as dividends to shareholders.

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

Net Income (Loss) Per Common Share

The Company calculates basic net income (loss) per common share by dividing net income (loss) to common shareholders for the period by weighted-average shares of common stock outstanding for that period. The Company did not have any potentially dilutive securities outstanding during the three or nine months endedSeptember 30, 2017 or September 30, 2016.

Holders of unvested shares of the Company's issued and outstanding restricted common stock are eligible to receive non-forfeitable dividends. As such, these unvested shares are considered participating securities as per ASC Topic 260-10 and therefore are included in the computation of basic net income (loss) per common 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 represents one unrestricted share of common stock.

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

Cash and Cash Equivalents

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

Restricted Cash

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

The Company early adopted Accounting Standards Update ("ASU") No. 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash, which requires amounts generally described as restricted cash or restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows. Because this ASU is to be applied retrospectively to each period presented, "net cash and cash equivalents used in financing activities" on the Company's consolidated statement of cash flows for the nine months endedSeptember 30, 2016 now omits "increase in restricted cash" previously reported in the Quarterly Report on Form 10-Q for that period, and that increase is now included within "net increase in cash, cash equivalents, and restricted cash" for that period in order to conform to the current period's presentation.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported on the Company's consolidated balance sheet as of September 30, 2017 that sum to the total of the same such amounts shown on the Company's consolidated statement of cash flows for the nine months endedSeptember 30, 2017:

	September 30, 2017
Cash and cash equivalents	$	117,702
Restricted cash	43,987
Total cash, cash equivalents, and restricted cash shown on consolidated statement of cash flows	$	161,689

Mortgage-Backed Securities

The Company's investments in Agency and non-Agency RMBS, CMBS, and CMBS IO securities are designated as available-for-sale ("AFS") and are recorded at fair value on the Company's consolidated balance sheet. Changes in unrealized gain (loss) on the Company's MBS are reported in other comprehensive income ("OCI") until it is sold, matures, or is 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 as collateral 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 the Company's Agency MBS as well as any non-Agency MBS rated 'AA' and higher at the time of purchase are amortized or accreted into interest income over the expected life of such securities using the effective yield method, and adjustments to premium amortization and discount accretion are made for actual cash payments. The Company may also adjust premium amortization and discount accretion for changes in projected future cash payments. The Company's projections of future cash payments are based on input and analysis received from external sources and internal models, and include assumptions about the amount and timing of loan prepayment rates, fluctuations in interest rates, credit losses, 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 does not estimate future prepayments on its fixed-rate Agency RMBS.

The Company holds certain non-Agency MBS that had credit ratings of less than 'AA' at the time of purchase or were not rated by any of the nationally recognized credit rating agencies. A portion of these non-Agency MBS were purchased at discounts to their par value, which management does not believe to be substantial. The discount is accreted into income over the security's expected life based on management's estimate of the security's projected cash flows. 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 5 for further discussion of MBS fair value measurements.

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

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

Repurchase Agreements

The Company's repurchase agreements, which are used to finance its purchases of MBS, 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 include interest rate swaps and forward contracts for the purchase or sale of generic Agency RMBS, commonly referred to as "TBA securities" or "TBA contracts". Derivative instruments are accounted for at the fair value of their unit of account. Derivative instruments in a gain position are reported as derivative assets and derivative instruments in a loss position are reported as derivative liabilities on the Company's consolidated balance sheet. All periodic interest costs and changes in fair value of derivative instruments, including gains and losses realized upon termination, maturity, or settlement are recorded in "gain (loss) on derivative instruments, net" on the Company's consolidated statement of comprehensive income. Cash receipts and payments related to derivative instruments are classified in the investing activities section of our consolidated statements of cash flows in accordance with the underlying nature or purpose of the derivative transactions.

Our interest rate swap agreements are privately negotiated in the over-the-counter ("OTC") market and the majority of these agreements are centrally cleared through the Chicago Mercantile Exchange ("CME") with the rest being subject to bilateral agreements between the Company and the swap counterparty. The Company's CME cleared swaps require that the Company post initial margin as determined by the CME, and in addition, variation margin is exchanged, typically in cash, for changes in the fair value of the CME cleared swaps. Beginning in January 2017, as a result of a change in the CME's rulebook, the exchange of variation margin for CME cleared swaps is legally considered to be the settlement of the derivative itself as opposed to a pledge of collateral. Accordingly, beginning in 2017, the Company accounts for the daily exchange of variation margin associated with its CME cleared interest rate swaps as a direct increase or decrease to the carrying value of the related derivative asset or liability. The carrying value of CME cleared interest rate swaps on the Company's consolidated balance sheets is the unsettled fair value of those instruments.

A TBA security is a forward contract for the purchase or sale of a generic Agency MBS at a predetermined price with certain principal and interest terms and certain types of collateral, but the particular Agency securities to be delivered are not identified until shortly before the TBA settlement date. The Company executes TBA dollar roll transactions which effectively delay the settlement of a forward purchase of a TBA Agency RMBS by entering into an offsetting short position (referred to as a "pair off"), net settling the paired-off positions in cash, and simultaneously entering a similar TBA contract for a later settlement date. TBA securities purchased for a forward settlement month are generally priced at a discount relative to TBA securities sold for settlement in the current month. This discount, often referred to as “drop income” is the economic equivalent of net interest income on the underlying Agency securities over the roll period (interest income less implied financing cost).

The Company accounts for TBA securities as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA contract that its settlement will result in physical delivery of the underlying Agency RMBS, or the individual TBA contract will not settle in the shortest time period possible.

Please refer to Note 4 for additional information regarding the Company's derivative instruments as well as Note 5 for information on how the fair value of these instruments are calculated.

Share-Based Compensation

Pursuant to the Company’s 2009 Stock and Incentive Plan, 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 time-based restricted stock 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 issued to its employees, officers, and directors.

Contingencies

In the normal course of business, there may be 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. The Company recognizes a liability 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.

Recent Accounting Pronouncements

The Financial Accounting Standards Board ("FASB") issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs, which shortens the amortization period for certain callable debt securities held at a premium, requiring the premium to be amortized to the earliest call date. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and early adoption is permitted. The amendments in this Update should be applied using the modified-retrospective transition approach and will require disclosures for the change in accounting principle. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements.

FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which contains significant amendments to hedge accounting with the main objective of better aligning an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both non-financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASU also includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness as well as changes to current disclosure requirements. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, and early adoption is permitted. All transition requirements and elections will be applied to hedging relationships existing on the date of adoption. The effect of adoption will be reflected as of the beginning of the fiscal year of adoption, and the amended presentation and disclosure guidance is required only prospectively. The Company does not currently apply hedge accounting, but is evaluating the impact this ASU would have on its consolidated financial statements if the Company elects to adopt hedge accounting in the future.

Non-Agency MBS	15,749		(199		)	11	81,660		(2,332		)	26

Because the principal related to Agency MBS is guaranteed by the government-sponsored entities Fannie Mae and Freddie Mac which have the implicit guarantee of the U.S. government, the Company does not consider any of the unrealized losses on its Agency MBS to be credit related. Although the unrealized losses are not credit related, the Company assesses its ability and intent to hold any Agency MBS with an unrealized loss until the recovery in its value in accordance with GAAP. This assessment is based on the amount of the unrealized loss and significance of the related investment as well as the Company’s leverage and liquidity position. Based on this analysis, the Company has determined that the unrealized losses on its Agency MBS as of September 30, 2017 and December 31, 2016 were temporary.

The Company 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 the non-Agency MBS, the credit characteristics of the mortgage loans collateralizing these securities, and the estimated future cash flows including projected collateral losses. The Company performed this evaluation for its 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 September 30, 2017 or December 31, 2016.

Wells Fargo Bank, N. A. and affiliates	$	349,965	2.10	%	$	57,992

Of the amount outstanding with Wells Fargo Bank, N.A. and affiliates, $343,780 is under a committed repurchase facility which has an aggregate maximum borrowing capacity of $400,000 and is scheduled to mature on May 12, 2019, 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 September 30, 2017 was 2.10%.

As of September 30, 2017, the Company had repurchase agreement amounts outstanding with 18 of its 34 available repurchase agreement 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 and earnings, 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 full compliance with all covenants as of September 30, 2017.

The Company's 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 repurchase agreements to these arrangements on a gross basis.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

DERIVATIVES

     The Company's derivative instruments include interest rate swaps and TBA securities. The Company utilizes interest rate swaps to economically hedge a portion of its exposure to interest rate risk in order 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 some portion of the Company's earnings from rising interest rates. The Company invests in TBA securities for the purchase or sale of Agency RMBS on a non-specified pool basis. TBA securities are forward contracts which are accounted for as derivative instruments; however, management views TBA securities as the economic equivalent of investing in and financing generic Agency fixed-rate RMBS through the repurchase agreement markets. 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 fair value by type of derivative instrument on the Company's consolidated balance sheets as of the dates indicated:  

		September 30, 2017			December 31, 2016
Type of Derivative Instruments	Balance Sheet Location	Fair Value			Fair Value (1)
Interest rate swaps	Derivative assets	$	368		$	28,534
TBA securities	Derivative assets	—			—

Interest rate swaps	Derivative liabilities	$	—		$	(6,922	)
TBA securities	Derivative liabilities	(133		)	—
		$	(133	)	$	(6,922	)

(1) Refer to Note 1 regarding information on a change in the CME rulebook. Amounts reported on the consolidated balance sheet as of September 30, 2017 for its interest rate swaps reflect the netting of the derivative asset or liability with the related collateral received or posted, respectively. The net amounts comparable to September 30, 2017 for the derivative asset and derivative liabilities as of December 31, 2016 were $104 and $(576), respectively.

The following tables present information about the Company's interest rate swaps as of the dates indicated:

Total	$	3,030,000	1.58	%	5.3	$	21,612

(1) The net notional amounts included in the tables above represent pay-fixed interest rate swaps, net of receive-fixed interest rate swaps and include $2,425,000 and $2,725,000 of pay-fixed forward starting interest rate swaps as of September 30, 2017 and December 31, 2016, respectively.

(2) Excluding forward starting pay-fixed interest rate swaps, the weighted average pay rate was 1.34% and 0.73% as of September 30, 2017 and December 31, 2016, respectively.

The following table summarizes information about the Company's TBA securities as of September 30, 2017:

	September 30, 2017
	Notional Amount (1)		Cost Basis (2)		Market Value (3)		Net Carrying Value (4)
30-year 4.0% TBA securities	$	650,000	$	683,813	$	683,680	$	(133	)

(1) Notional amount represents the par value (or principal balance) of the underlying Agency MBS.

(2) Cost basis represents the forward price to be paid for the underlying Agency MBS as if settled.

(3) Market value is the current fair value of the TBA contract and represents the estimated fair value of the underlying Agency security as of the end of the period.

(4) Net carrying value represents the difference between the market value and the cost basis of the TBA contract as of the end of the period and is included on the consolidated balance sheets within "derivative assets (liabilities)".

The tables below summarize changes in our derivative instruments for the periods indicated:

Type of Derivative Instrument	Notional Amount as of December 31, 2016		Additions		Settlements, Terminations, or Pair-Offs			Notional Amount as of September 30, 2017
Receive-fixed interest rate swaps	$	425,000	$	—	$	(325,000	)	$	100,000

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

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
Type of Derivative Instrument	2017			2016			2017			2016
Receive-fixed interest rate swaps	$	(99	)	$	(2,976	)	$	746		$	11,301

Gain (loss) on derivative instruments, net	$	5,993		$	2,409		$	(9,634	)	$	(62,153	)

There is a net unrealized gain of $450 remaining in AOCI on the Company's consolidated balance sheet as of September 30, 2017 which represents the activity related to 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 an adjustment to "interest expense" over the remaining contractual life of the agreements. The Company estimates a credit of $210 will be reclassified to net income as a reduction of "interest expense" within the next 12 months.

A portion of the Company's interest rate swaps were entered into under bilateral agreements which contain cross-default provisions with other agreements between the parties. In addition, these bilateral agreements contain financial and operational covenants similar to those contained in our repurchase agreements as described in Note 3. The Company was in compliance with all covenants with respect to bilateral agreements under which interest rate swaps were entered into as of September 30, 2017.

The Company's derivatives 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 derivative assets and liabilities subject to these arrangements on a gross basis. The following tables present information regarding those derivative assets and liabilities subject to such arrangements as if the Company had presented them on a net basis as of September 30, 2017 and December 31, 2016:

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 Company reviews the classification of its financial instruments within the fair value hierarchy on a quarterly basis, and management may conclude that its financial instruments should be reclassified to a different level in the future if a change in type of inputs occurs. 

The following table presents the fair value of the Company’s financial instruments 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:

	September 30, 2017
	Fair Value		Level 1 - Unadjusted Quoted Prices in Active Markets		Level 2 - Observable Inputs		Level 3 - Unobservable Inputs
Assets:
Mortgage-backed securities	$	2,921,444	$	—	$	2,913,877	$	7,567
Interest rate swaps	368		—		368		—
Total assets carried at fair value	$	2,921,812	$	—	$	2,914,245	$	7,567
Liabilities:
TBA securities	133		—		133		—
Total liabilities carried at fair value	$	133	$	—	$	133	$	—
	December 31, 2016
	Fair Value		Level 1 - Unadjusted Quoted Prices in Active Markets		Level 2 - Observable Inputs		Level 3 - Unobservable Inputs
Assets:
Mortgage-backed securities	$	3,212,084	$	—	$	3,201,157	$	10,927
Interest rate swaps	28,534		—		28,534		—
Total assets carried at fair value	$	3,240,618	$	—	$	3,229,691	$	10,927
Liabilities:
Interest rate swaps	$	6,922	$	—	$	6,922	$	—
Total liabilities carried at fair value	$	6,922	$	—	$	6,922	$	—

The fair value measurements for a majority of the Company's MBS are considered Level 2. These Level 2 securities are substantially similar to securities that either are actively traded or have been recently traded in their respective markets. The Company determines the fair value of its Level 2 securities based on prices received from the Company's primary pricing service as well as other pricing services and brokers. The Company evaluates the third party prices it receives to assess their reasonableness. Although the Company does not adjust third party prices, they may be excluded from use in the determination of a security's fair value if they are significantly different from other observable market data. In valuing a security, the primary pricing service uses either a market approach, which uses observable prices and other relevant information that is generated by market transactions of identical or similar securities, or an income approach, which uses valuation techniques to convert future amounts to a single, discounted present value amount. The Company also reviews the assumptions and inputs utilized in the valuation techniques of its primary pricing service. Examples of these observable inputs and assumptions include market interest rates, credit spreads, and projected prepayment speeds, among other things.

The fair value of interest rate swaps are measured 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 as of September 30, 2017 and December 31, 2016. The fair value of TBA securities are estimated using methods similar those used to fair value the Company's Level 2 MBS.

The Company owns certain non-Agency MBS for which there are not sufficiently recent trades of substantially similar securities, and their fair value measurements are thus considered Level 3. The Company determines the fair value of its Level 3 securities by discounting the estimated future cash flows derived from cash flow models using significant inputs which are determined by the Company when market observable inputs are not available. 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 may result in a significantly different fair value measurement. Level 3 assets are generally most sensitive to the default rate and severity assumptions.

The activity of the instruments measured at fair value on a recurring basis using Level 3 inputs is presented in the following table for the period indicated:

	Level 3 Fair Value
	Non-Agency CMBS			Non-Agency RMBS			Total
Balance as of December 31, 2016	$	9,669		$	1,258		$	10,927
Unrealized loss included in OCI (1)	(1,422		)	16			(1,406		)

Accretion	2,075			—			2,075
Balance as of September 30, 2017	$	6,426		$	1,141		$	7,567

(1) Amount included in "unrealized gain on available-for-sale investments, net" on consolidated statements of comprehensive income (loss).

The following table presents a summary of the carrying value and estimated fair values of the Company’s financial instruments as of the dates indicated:

Shareholders' Equity

SHAREHOLDERS' EQUITY AND SHARE-BASED COMPENSATION

Preferred Stock

The Company's articles of incorporation authorize the issuance of up to 50,000,000 shares of preferred stock, par value $0.01 per share, of which the Company's Board of Directors has designated 8,000,000 shares of 8.50% Series A Preferred Stock and 7,000,000 shares of 7.625% Series B Preferred Stock, (the Series A Preferred Stock and the Series B Preferred Stock collectively, the "Preferred Stock"). The Company had 2,300,000 shares of its Series A Preferred Stock and 3,365,101 shares of its Series B Preferred Stock issued and outstanding as of September 30, 2017 compared to 2,300,000 shares of Series A Preferred Stock and 2,271,937 shares of Series B Preferred Stock as of December 31, 2016.

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. The Company's Series A Preferred Stock may be redeemed in whole, or in part, at any time and from time to time at the Company's option at a cash redemption price of $25.00 per share plus any accumulated and unpaid dividends. Except under certain limited circumstances, the Company may not redeem the Series B Preferred Stock prior to April 30, 2018.

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 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. The Company paid its regular quarterly dividends on its Preferred Stock for the third quarter on October 16, 2017 to shareholders of record as of October 1, 2017.

Preferred Stock

Preferred Stock

The Company's articles of incorporation authorize the issuance of up to 50,000,000 shares of preferred stock, par value $0.01 per share, of which the Company's Board of Directors has designated 8,000,000 shares of 8.50% Series A Preferred Stock and 7,000,000 shares of 7.625% Series B Preferred Stock, (the Series A Preferred Stock and the Series B Preferred Stock collectively, the "Preferred Stock"). The Company had 2,300,000 shares of its Series A Preferred Stock and 3,365,101 shares of its Series B Preferred Stock issued and outstanding as of September 30, 2017 compared to 2,300,000 shares of Series A Preferred Stock and 2,271,937 shares of Series B Preferred Stock as of December 31, 2016.

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. The Company's Series A Preferred Stock may be redeemed in whole, or in part, at any time and from time to time at the Company's option at a cash redemption price of $25.00 per share plus any accumulated and unpaid dividends. Except under certain limited circumstances, the Company may not redeem the Series B Preferred Stock prior to April 30, 2018. On or after April 30, 2018, the Company's Series B Preferred Stock may be redeemed in whole, or in part, at any time and from time to time at the Company's option at a cash redemption price of $25.00 per share plus any accumulated and unpaid dividends. 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 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. The Company paid its regular quarterly dividends on its Preferred Stock for the third quarter on October 16, 2017 to shareholders of record as of October 1, 2017.

Organization and Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2017

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 specified pools of Agency and non-Agency mortgage-backed securities (“MBS”) consisting of residential MBS (“RMBS”), commercial MBS (“CMBS”) and CMBS interest-only ("IO") securities 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"). We also invest in other types of mortgage-related securities, such as to-be-announced (“TBA”) forward contracts for the purchase or sale of generic (also referred to as "non-specified") pools of Agency MBS.

Basis of Presentation [Policy Text Block]

Basis of Presentation

The accompanying unaudited consolidated financial statements of Dynex Capital, Inc. and its subsidiaries (together, “Dynex” or, as appropriate, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10, Rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all significant adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the consolidated financial statements have been included. Operating results for the three months endedSeptember 30, 2017 are not necessarily indicative of the results that may be expected for any other interim periods or for the entire year ending December 31, 2017. The unaudited consolidated financial statements included herein should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC.

Consolidation [Policy Text Block]

Consolidation

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

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, amortization of premiums and discounts, fair value measurements of its investments, and other-than-temporary impairments. These items are discussed further below within this note to the consolidated financial statements.

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 ("NOL") 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 capital gains that is distributed as dividends to shareholders.

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

Net Income (Loss) Per Common Share [Text Block]

Net Income (Loss) Per Common Share

The Company calculates basic net income (loss) per common share by dividing net income (loss) to common shareholders for the period by weighted-average shares of common stock outstanding for that period. The Company did not have any potentially dilutive securities outstanding during the three or nine months endedSeptember 30, 2017 or September 30, 2016.

Holders of unvested shares of the Company's issued and outstanding restricted common stock are eligible to receive non-forfeitable dividends. As such, these unvested shares are considered participating securities as per ASC Topic 260-10 and therefore are included in the computation of basic net income (loss) per common 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 represents one unrestricted share of common stock.

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

Cash and Cash Equivalents [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.

Restricted Cash [Policy Text Block]

Restricted Cash

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

The Company early adopted Accounting Standards Update ("ASU") No. 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash, which requires amounts generally described as restricted cash or restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows. Because this ASU is to be applied retrospectively to each period presented, "net cash and cash equivalents used in financing activities" on the Company's consolidated statement of cash flows for the nine months endedSeptember 30, 2016 now omits "increase in restricted cash" previously reported in the Quarterly Report on Form 10-Q for that period, and that increase is now included within "net increase in cash, cash equivalents, and restricted cash" for that period in order to conform to the current period's presentation.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported on the Company's consolidated balance sheet as of September 30, 2017 that sum to the total of the same such amounts shown on the Company's consolidated statement of cash flows for the nine months endedSeptember 30, 2017:

	September 30, 2017
Cash and cash equivalents	$	117,702
Restricted cash	43,987
Total cash, cash equivalents, and restricted cash shown on consolidated statement of cash flows	$	161,689

Mortgage-Backed Securities [Policy Text Block]

Mortgage-Backed Securities

The Company's investments in Agency and non-Agency RMBS, CMBS, and CMBS IO securities are designated as available-for-sale ("AFS") and are recorded at fair value on the Company's consolidated balance sheet. Changes in unrealized gain (loss) on the Company's MBS are reported in other comprehensive income ("OCI") until it is sold, matures, or is 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 as collateral 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 the Company's Agency MBS as well as any non-Agency MBS rated 'AA' and higher at the time of purchase are amortized or accreted into interest income over the expected life of such securities using the effective yield method, and adjustments to premium amortization and discount accretion are made for actual cash payments. The Company may also adjust premium amortization and discount accretion for changes in projected future cash payments. The Company's projections of future cash payments are based on input and analysis received from external sources and internal models, and include assumptions about the amount and timing of loan prepayment rates, fluctuations in interest rates, credit losses, 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 does not estimate future prepayments on its fixed-rate Agency RMBS.

The Company holds certain non-Agency MBS that had credit ratings of less than 'AA' at the time of purchase or were not rated by any of the nationally recognized credit rating agencies. A portion of these non-Agency MBS were purchased at discounts to their par value, which management does not believe to be substantial. The discount is accreted into income over the security's expected life based on management's estimate of the security's projected cash flows. 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 5 for further discussion of MBS fair value measurements.

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

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

Repurchase Agreements [Policy Text Block]

Repurchase Agreements

The Company's repurchase agreements, which are used to finance its purchases of MBS, 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 include interest rate swaps and forward contracts for the purchase or sale of generic Agency RMBS, commonly referred to as "TBA securities" or "TBA contracts". Derivative instruments are accounted for at the fair value of their unit of account. Derivative instruments in a gain position are reported as derivative assets and derivative instruments in a loss position are reported as derivative liabilities on the Company's consolidated balance sheet. All periodic interest costs and changes in fair value of derivative instruments, including gains and losses realized upon termination, maturity, or settlement are recorded in "gain (loss) on derivative instruments, net" on the Company's consolidated statement of comprehensive income. Cash receipts and payments related to derivative instruments are classified in the investing activities section of our consolidated statements of cash flows in accordance with the underlying nature or purpose of the derivative transactions.

Our interest rate swap agreements are privately negotiated in the over-the-counter ("OTC") market and the majority of these agreements are centrally cleared through the Chicago Mercantile Exchange ("CME") with the rest being subject to bilateral agreements between the Company and the swap counterparty. The Company's CME cleared swaps require that the Company post initial margin as determined by the CME, and in addition, variation margin is exchanged, typically in cash, for changes in the fair value of the CME cleared swaps. Beginning in January 2017, as a result of a change in the CME's rulebook, the exchange of variation margin for CME cleared swaps is legally considered to be the settlement of the derivative itself as opposed to a pledge of collateral. Accordingly, beginning in 2017, the Company accounts for the daily exchange of variation margin associated with its CME cleared interest rate swaps as a direct increase or decrease to the carrying value of the related derivative asset or liability. The carrying value of CME cleared interest rate swaps on the Company's consolidated balance sheets is the unsettled fair value of those instruments.

A TBA security is a forward contract for the purchase or sale of a generic Agency MBS at a predetermined price with certain principal and interest terms and certain types of collateral, but the particular Agency securities to be delivered are not identified until shortly before the TBA settlement date. The Company executes TBA dollar roll transactions which effectively delay the settlement of a forward purchase of a TBA Agency RMBS by entering into an offsetting short position (referred to as a "pair off"), net settling the paired-off positions in cash, and simultaneously entering a similar TBA contract for a later settlement date. TBA securities purchased for a forward settlement month are generally priced at a discount relative to TBA securities sold for settlement in the current month. This discount, often referred to as “drop income” is the economic equivalent of net interest income on the underlying Agency securities over the roll period (interest income less implied financing cost).

The Company accounts for TBA securities as derivative instruments because the Company cannot assert that it is probable at inception and throughout the term of an individual TBA contract that its settlement will result in physical delivery of the underlying Agency RMBS, or the individual TBA contract will not settle in the shortest time period possible.

Please refer to Note 4 for additional information regarding the Company's derivative instruments as well as Note 5 for information on how the fair value of these instruments are calculated.

Stock-based Compensation [Policy Text Block]

Share-Based Compensation

Pursuant to the Company’s 2009 Stock and Incentive Plan, 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 time-based restricted stock 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 issued to its employees, officers, and directors.

Contingencies [Policy Text Block]

Contingencies

In the normal course of business, there may be 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. The Company recognizes a liability 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.

Recent Accounting Pronouncements [Text Block]

Recent Accounting Pronouncements

The Financial Accounting Standards Board ("FASB") issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs, which shortens the amortization period for certain callable debt securities held at a premium, requiring the premium to be amortized to the earliest call date. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and early adoption is permitted. The amendments in this Update should be applied using the modified-retrospective transition approach and will require disclosures for the change in accounting principle. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements.

FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which contains significant amendments to hedge accounting with the main objective of better aligning an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both non-financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASU also includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness as well as changes to current disclosure requirements. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, and early adoption is permitted. All transition requirements and elections will be applied to hedging relationships existing on the date of adoption. The effect of adoption will be reflected as of the beginning of the fiscal year of adoption, and the amended presentation and disclosure guidance is required only prospectively. The Company does not currently apply hedge accounting, but is evaluating the impact this ASU would have on its consolidated financial statements if the Company elects to adopt hedge accounting in the future.
