Organization and Business Description	'
	1.       Organization and Business Description
	Hatteras Financial Corp. (the “Company”) was incorporated in Maryland on September 19, 2007.  The Company invests primarily in single-family residential mortgage assets, such as mortgage-backed securities (“MBS”), issued or guaranteed by the U.S. Government, such as Ginnie Mae, or by the U.S. Government sponsored enterprises, such as Fannie Mae and Freddie Mac (“agency securities”).  The Company is externally managed by Atlantic Capital Advisors LLC (“ACA”).
	The Company has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”).  As a result, the Company does not pay federal income taxes on taxable income distributed to shareholders if certain REIT qualification tests are met.  It is the Company’s policy to distribute 100% of its taxable income, after application of available tax attributes, within the time limits prescribed by the Code, which may extend into the subsequent taxable year.  However, the Company may conduct certain activities that cause it to earn income which will not be qualifying income for REIT purposes.  The Company has designated certain of its subsidiaries as taxable REIT subsidiaries (“TRSs”) as defined in the Code to engage in such activities, and the Company may in the future form additional TRSs.

	2.       Summary of Significant Accounting Policies
	Basis of Presentation and Use of Estimates
	The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.  In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.  Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2014.  These unaudited consolidated financial statements 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, 2013.
	The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Significant estimates affecting the accompanying consolidated financial statements include the valuation of agency securities and derivative instruments.
	Certain prior period amounts have been reclassified to conform to the current period presentation.
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and all of its subsidiaries.  The Company also considers the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 810 on Consolidation in determining whether consolidation is appropriate for any interests held in variable interest entities.  All significant intercompany balances and transactions have been eliminated.
	Financial Instruments
	The Company considers its cash and cash equivalents, restricted cash, agency securities (settled and unsettled), forward purchase commitments, debt security held to maturity, receivable for securities sold, accrued interest receivable, principal payment receivable, payable for unsettled securities, derivative instruments, repurchase agreements, dollar roll liabilities and accrued interest payable to meet the definition of financial instruments.  The carrying amount of cash and cash equivalents, restricted cash, receivable for securities sold, accrued interest receivable, dollar roll liabilities and payable for unsettled securities approximate their fair value due to the short maturities of these instruments and are valued using Level 1 inputs.  The carrying amount of repurchase agreements is deemed to approximate fair value given their short-term duration and would be valued using Level 2 inputs.  See Note 4 and 7 for discussion of the fair value of agency securities and forward purchase commitments, respectively.  See Note 5 for discussion of the fair value of the held to maturity debt security.  See Note 7 for discussion of the fair value of derivative instruments.
	The Company limits its exposure to credit losses on its portfolio of securities by purchasing predominantly agency securities.  The portfolio is diversified to avoid undue exposure to loan originator, geographic and other types of concentration.  The Company manages the risk of prepayments of the underlying mortgages by creating a diversified portfolio with a variety of expected prepayment characteristics.  See Note 4 for additional information on MBS.
	The Company is engaged in various trading and brokerage activities including repurchase agreements, dollar roll transactions, interest rate swap agreements, interest rate swaptions and futures contracts in which counterparties primarily include broker-dealers, banks, and other financial institutions.  In the event counterparties do not fulfill their obligations, the Company may be exposed to risk of loss.  The risk of default depends on the creditworthiness of the counterparty and/or issuer of the instrument.  It is the Company’s policy to review, as necessary, the credit standing for each counterparty.  See Note 6 for additional information on repurchase agreements and Note 7 for additional information on dollar roll transactions, interest rate swap agreements, interest rate swaptions and futures contracts.
	Mortgage-Backed Securities
	The Company invests predominantly in agency securities representing interests in or obligations backed by pools of single-family residential mortgage loans.  Guidance under the FASB ASC Topic 320 on Investments requires the Company to classify its investments as either trading, available-for-sale or held-to-maturity securities.  Management determines the appropriate classifications of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date.  The Company currently classifies all of its agency securities as available-for-sale.  All assets that are classified as available-for-sale are carried at fair value and unrealized gains and losses are included in other comprehensive income (loss).  The estimated fair values of agency securities are determined by management by obtaining valuations for its agency securities from independent sources and averaging these valuations.  Security purchase and sale transactions are recorded on the trade date.  Gains or losses realized from the sale of securities are included in income and are determined using the specific identification method.
	Forward purchase commitments to acquire “when issued” or to-be-announced (“TBA”) securities are recorded at fair value in accordance with ASC Topic 815, Derivatives and Hedging (“ASC 815”).  The fair value of these forward purchase commitments is included in derivative assets or derivative liabilities in the accompanying consolidated balance sheets.  If the Company intends to take physical delivery of the securities, as is the case for forward purchase commitments to acquire TBA securities from mortgage originators, the commitment is designated as an all-in-one cash flow hedge and its unrealized gains and losses are recorded in other comprehensive income.  If the Company does not intend to take physical delivery, as is the case with TBA dollar roll transactions, the commitment is not designated as an accounting hedge and unrealized gains and losses are recorded in “Gain (loss) on derivative instruments, net.” See note 7 for additional information on forward purchase commitments.
	The Company assesses its investment securities for other-than-temporary impairment on at least a quarterly basis.  When the fair value of an investment is less than its amortized cost at the balance sheet date the impairment is designated as either “temporary” or “other-than-temporary.” In deciding on whether or not a security is other than temporarily impaired, the Company uses a two-step evaluation process.  First, the Company determines whether it has made any decision to sell a security that is in an unrealized loss position, or, if not, the Company determines whether it is more likely than not that the Company will be required to sell the security prior to recovering its amortized cost basis.  If the answer to either of these questions is “yes” then the security is considered other-than-temporarily impaired.  No impairment losses were recognized during the periods presented.
	Derivative Instruments
	The Company manages economic risks, including interest rate, liquidity and credit risks, primarily by managing the amount, sources, cost, and duration of its debt funding.  The objectives of the Company’s risk management strategy are 1) to attempt to mitigate the risk of the cost of its variable rate liabilities increasing during a period of rising interest rates, and 2) to reduce fluctuations in net book value over a range of interest rate scenarios.  The principal instruments that the Company uses to achieve these objectives are interest rate swaps and Eurodollar Futures Contracts (“Futures Contracts”).  The Company uses Futures Contracts to approximate the economic hedging results achieved with interest rate swaps.  The Company does not enter into any of these transactions for speculative purposes.
	The Company accounts for derivative instruments in accordance with ASC 815, which requires an entity to recognize all derivatives as either assets or liabilities and to measure those instruments at fair value.  The accounting for changes in the fair value of derivative instruments depends on whether the instruments are designated and qualify as part of a hedging relationship pursuant to ASC 815.  Changes in fair value related to derivatives not in hedge designated relationships are recorded in “Gain (loss) on derivative instruments, net” in the Company’s consolidated statements of income, whereas changes in fair value related to derivatives in hedge designated relationships are initially recorded in other comprehensive income (loss) and later reclassified to income at the time that the hedged transactions affect earnings.  Any portion of the changes in fair value due to hedge ineffectiveness is immediately recognized in the income statement.
	Derivative instruments in a gain position are reported as derivative assets and derivative instruments in a loss position are reported as derivative liabilities in the Company’s consolidated balance sheets.  In the Company’s consolidated statements of cash flows, cash receipts and payments related to derivative instruments are classified according to the underlying nature or purpose of the derivative transaction, generally in the operating section if the derivatives are designated as accounting hedges and in the investing section otherwise.  The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts.  The Company attempts to minimize this risk by limiting its counterparties to major financial institutions with acceptable credit ratings, monitoring positions with individual counterparties and adjusting posted collateral as required.
	All of the Company’s interest rate swaps have historically been accounted for as cash flow hedges under ASC 815.  However, on September 30, 2013, the Company discontinued hedge accounting for its interest rate swap agreements by de-designating the interest rate swaps as cash flow hedges.  No interest rate swaps were terminated in conjunction with this action, and the Company’s risk management and hedging practices were not impacted.  As a result of discontinuing hedge accounting, beginning October 1, 2013 changes in the fair value of the Company’s interest rate swap agreements are recorded in “Gain (loss) on derivative instruments, net” in the Company’s consolidated statements of income, rather than in other comprehensive income (loss).  Also, net interest paid or received under the interest rate swaps, which up through September 30, 2013 was recognized in “interest expense,” is instead recognized in “Gain (loss) on derivative instruments, net.” These interest rate swaps continue to be reported as assets or liabilities on the Company’s consolidated balance sheets at their fair value.
	As long as the forecasted transactions that were being hedged (i.e. rollovers of the Company’s repurchase agreement borrowings) are still expected to occur, the balance in accumulated other comprehensive income (AOCI) from interest rate swap activity up through September 30, 2013 will remain in AOCI and be recognized in the Company’s consolidated statements of income as “interest expense” over the remaining term of the interest rate swaps.  See Note 7 for further information.
	The Company may also enter into forward purchase commitments as a means of investing in and financing agency securities via TBA dollar roll transactions.  TBA dollar roll transactions involve moving the settlement of a TBA contract out to a later date by entering into an offsetting short position (referred to as a “pair off”), net settling the paired off positions for cash, and simultaneously purchasing a similar TBA contract for a later settlement date.  The agency securities purchased at the later settlement date are typically priced at a discount to securities for settlement in the current month.  This difference is referred to as the “price drop.” The price drop represents compensation to the Company for foregoing net interest margin (interest income less repurchase agreement financing cost) and is referred to as “dollar roll income,” which the Company classifies in “Gain (loss) on derivative instruments, net.” Realized and unrealized gains and losses related to TBA dollar roll transactions are also recognized in “Gain (loss) on derivative instruments, net.” TBA dollar roll transactions represent off-balance sheet financing.
	Repurchase Agreements
	The Company finances the acquisition of its agency securities through the use of repurchase agreements.  Under these repurchase agreements, the Company sells securities to a lender and agrees to repurchase the same securities in the future for a price that is higher than the original sales price.  The difference between the sale price that the Company receives and the repurchase price that the Company pays represents interest paid to the lender.  Although structured as a sale and repurchase obligation, a repurchase agreement operates as a financing 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 records repurchase agreements on the consolidated balance sheets at the amount of cash received (or contract value), with accrued interest recorded separately.  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 such agreement at the then prevailing financing rate.  These repurchase agreements may require the Company to pledge additional assets to the lender in the event the estimated fair value of the existing pledged collateral declines.
	Dollar Roll Liability
	In addition to the TBA dollar roll transactions described above, the Company may from time to time execute dollar roll transactions on agency securities (“CUSIP dollar rolls”).  These transactions represent on-balance sheet financing, presented as “Dollar roll liability” in the Company’s consolidated balance sheets.  During the period of a CUSIP dollar roll, the financed security remains on the Company’s balance sheet, and the components of the net interest margin earned from the price drop are classified in “interest income on mortgage-backed securities” and “interest expense,” respectively.
	Offsetting of Assets and Liabilities
	The Company’s derivative agreements and repurchase agreements generally contain provisions that allow for netting or the offsetting of receivables and payables with each counterparty.  The Company reports amounts in its consolidated balance sheets on a gross basis without regard for such rights of offset or master netting arrangements.
	Interest Income
	Interest income is earned and recognized based on the outstanding principal amount of the investment securities and their contractual terms.  Premiums and discounts associated with the purchase of the investment securities are amortized or accreted into interest income over the actual lives of the securities using the effective interest method.
	Income Taxes
	The Company has elected to be taxed as a REIT under the Code.  The Company will generally not be subject to federal income tax to the extent that it distributes 100% of its taxable income, after application of available tax attributes, within the time limits prescribed by the Code and as long as it satisfies the ongoing REIT requirements including meeting certain asset, income and stock ownership tests.  The Company has made an election to treat certain of its subsidiaries as TRSs.  These TRSs are taxable as domestic C corporations and are subject to federal, state and local income taxes based upon their taxable income.
	Share-Based Compensation
	Share-based compensation is accounted for under the guidance included in the ASC Topic on Stock Compensation.  For share and share-based awards issued to employees, a compensation charge is recorded in earnings based on the fair value of the award.  For transactions with non-employees in which services are performed in exchange for the Company’s common stock or other equity instruments, the transactions are recorded on the basis of the fair value of the service received or the fair value of the equity instruments issued, whichever is more readily measurable at the date of issuance.  The Company’s share-based compensation transactions resulted in compensation expense of $842 and $627 for the three months ended June 30, 2014 and 2013, respectively.  Share-based compensation expense was $1,702 and $1,256 for the six months ended June 30, 2014 and 2013, respectively.
	Earnings Per Common Share (EPS)
	Basic EPS is computed by dividing net income less preferred stock dividends to arrive at net income available to holders of common stock by the weighted average number of shares of common stock outstanding during the period.  Diluted EPS is computed using the two class method, as described in the ASC Topic on Earnings Per Share, which takes into account certain adjustments related to participating securities.  Participating securities are unvested share-based awards that contain rights to receive nonforfeitable dividends, such as those awarded under the Company’s equity incentive plan.  Net income available to holders of common stock after deducting dividends on unvested participating securities if antidilutive, is divided by the weighted average shares of common stock and common equivalent shares outstanding during the period.  For the diluted EPS calculation, common equivalent shares outstanding includes the weighted average number of shares of common stock outstanding adjusted for the effect of dilutive unexercised stock options, if any.
	Recent Accounting Pronouncements
	In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing: Repurchase-to-Maturity Transaction, Repurchase Financings, and Disclosures (the ASU).  This guidance requires repurchase-to-maturity transactions to be accounted for as secured borrowings as if the transferor retains effective control, even though the transferred financial assets are not returned to the transferor at settlement. The ASU also eliminates existing guidance for repurchase financings and requires instead that entities consider the initial transfer and the related repurchase agreement separately when applying the derecognition requirements of ASC 860, Transfers and Servicing. New disclosures will be required for (1) certain transactions accounted for as secured borrowings and (2) transfers accounted for as sales when the transferor also retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction.  This guidance will take effect for periods beginning after December 15, 2014, and early adoption is prohibited.  Certain disclosures under this guidance do not take effect until the first period beginning after March 15, 2015.  The Company is currently assessing the impact of this guidance.

	The Company’s valuation techniques for financial instruments are based on observable and unobservable inputs.  Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect the Company’s market assumptions.  The ASC Topic on Fair Value Measurements classifies these inputs into the following hierarchy:
	Level 1 Inputs– Quoted prices for identical instruments in active markets.
	Level 2 Inputs– Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
	Level 3 Inputs– Instruments with primarily unobservable value drivers.
	Other than the Futures Contracts, all of the Company’s agency securities and other derivatives were valued using Level 2 inputs at June 30, 2014 and December 31, 2013.  The Futures Contracts were valued using Level 1 inputs at June 30, 2014 and December 31, 2013.  See Notes 4 and 7, respectively, for discussion on how agency securities and derivatives were valued.
	The carrying values and fair values of all financial instruments as of June 30, 2014 and December 31, 2013 were as follows.

	4.      Mortgage-Backed Securities
	All of the Company’s agency securities were classified as available-for-sale and, as such, are reported at their estimated fair value.  The agency securities market is primarily an over-the-counter market.  As such, there are no standard, public market quotations or published trading data for individual agency securities.  The Company estimates the fair value of the Company’s agency securities based on a market approach obtaining values for its securities primarily from third-party pricing services and dealer quotes.  To ensure the Company’s fair value determinations are consistent with the ASC Topic on Fair Value Measurements and Disclosures, the Company regularly reviews the prices obtained and the methods used to derive those prices.  The Company evaluates the pricing information it receives taking into account factors such as coupon, prepayment experience, fixed/adjustable rate, annual and life caps, coupon index, time to next reset and issuing agency, among other factors to ensure that estimated fair values are appropriate.  The Company reviews the methods and inputs used by providers of pricing data to determine that the fair value of its assets and liabilities are properly classified in the fair value hierarchy.
	The third-party pricing services gather trade data and use pricing models that incorporate such factors as coupons, primary mortgage rates, prepayment speeds, spread to the U.S. Treasury and interest rate swap curves, periodic and life caps and other similar factors.  Traders at broker-dealers function as market-makers for these securities, and these brokers have a direct view of the trading activity.
	Brokers do not receive compensation for providing pricing information to the Company.  The broker prices received are non-binding bids to trade.  The brokers receive data from traders that participate in the active markets for these securities and directly observe numerous trades of securities similar to the securities owned by the Company.  The Company’s analysis of fair value for these includes comparing the data received to other information, if available, such as repurchase agreement pricing or internal pricing models.
	If the fair value of a security is not available using the Level 2 inputs as described above, or such data appears unreliable, the Company may estimate the fair value of the security using a variety of methods including, but not limited to, other independent pricing services, repurchase agreement pricing, discounted cash flow analysis, matrix pricing, option adjusted spread models and other fundamental analysis of observable market factors.  At June 30, 2014 and December 31, 2013, all of the Company’s agency securities values were based on third-party sources.
	The Company’s investment portfolio consists of agency securities, which are backed by a U.S. Government agency or a U.S. Government sponsored enterprise.  The following table presents certain information about the Company’s agency securities at June 30, 2014.

The Company did not make the decision to sell the above securities as of June 30, 2014 and December 31, 2013, nor was it deemed more likely than not the Company would be required to sell these securities before recovery of their amortized cost basis.  The unrealized losses on the above securities are the result of market interest rates and are not considered to be credit related.
The contractual maturity of the Company’s agency securities ranges from 15 to 30 years.  Because of prepayments on the underlying mortgage loans, the actual weighted-average maturity is expected to be significantly less than the stated maturity.

	7.       Derivatives and Other Hedging Instruments
	In connection with the Company’s risk management strategy, the Company hedges a portion of its interest rate risk by entering into derivative contracts.  The Company may enter into agreements for interest rate swaps, interest rate swaptions, interest rate cap or floor contracts and futures or forward contracts.  The Company’s risk management strategy attempts to manage the overall risk of the portfolio, reduce fluctuations in book value and generate additional income distributable to shareholders.  For additional information regarding the Company’s derivative instruments and its overall risk management strategy, please refer to the discussion of derivative instruments in Note 2.
	The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts).  The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.  The fair value of interest rate swaptions is based on third party broker quotations that are non binding bids to trade.  The fair value of Futures Contracts is based on quoted prices from the exchange on which they trade.  The fair value of forward purchase commitments was determined using the same methodology as agency securities as described in Note 4.  The table below presents the fair value of the Company’s derivative instruments as well as their classification on the consolidated balance sheets as of June 30, 2014 and December 31, 2013, respectively.

	Interest Rate Swaps and Swaptions
	The Company finances its activities primarily through repurchase agreements, which are generally settled on a short-term basis, usually from one to three months.  At each settlement date, the Company refinances each repurchase agreement at the market interest rate at that time.  Since the Company is exposed to interest rates on its borrowings that change on a short term basis, it enters into hedging agreements to mitigate the effect of these changes.  Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreement without exchange of the underlying notional amount.  The effect of these hedges is to synthetically lockup interest rates on a portion of the Company’s repurchase agreements for the terms of the interest rate swaps.  Although the Company’s objective is to hedge the risk associated with changing repurchase agreement rates, the Company’s interest rate swaps are benchmark interest rate swaps which perform with reference to LIBOR.  Therefore, the Company remains at risk to the variability of the spread between repurchase agreement rates and LIBOR interest rates.
	Until September 30, 2013, the Company elected cash flow hedge accounting for its interest rate swaps.  Under cash flow hedge accounting, effective hedge gains or losses are initially recorded in other comprehensive income and subsequently reclassified into net income in the period that the hedged forecasted transaction affects earnings.  Ineffective hedge gains and losses are recorded on a current basis in earnings.  The hedge ineffectiveness is attributable primarily to differences in the reset dates on the Company’s interest rate swaps versus the refinancing dates of its repurchase agreements.  See “Financial Statement Presentation” below for quantification of gains and losses on interest rate swaps for the three months and six months ended June 30, 2014 and 2013.
	On September 30, 2013, the Company de-designated its interest rate swaps as cash flow hedges, thus terminating cash flow hedge accounting.  As long as the forecasted rollovers of the related repurchase agreements are still expected to occur, amounts in AOCI related to the cash flow hedges through September 30, 2013 will remain in AOCI and will continue to be reclassified to interest expense as interest is accrued and paid on the related repurchase agreements.  During the next 12 months, the Company estimates that an additional $59,146 will be reclassified out of AOCI as an increase to interest expense.
	The Company continues to hedge its exposure to variability in future funding costs via interest rate swaps and other derivative instruments.  As a result of discontinuing hedge accounting, beginning October 1, 2013, changes in the fair value of the Company’s interest rate swaps are recorded in “Gain (loss) on derivative instruments, net” in the consolidated statements of income, consistent with the Company’s historical accounting for Futures Contracts, as described below.  Monthly net cash settlements under the interest rate swaps are also recorded in “Gain (loss) on derivative instruments, net” beginning October 1, 2013.
	The volume of activity for the Company’s interest rate swap instruments is shown in the table below.

	The Company has not designated its Futures Contracts as hedges for accounting purposes.  As a result, realized and unrealized changes in fair value thereon are recognized in earnings in the period in which the changes occur.  See “Financial Statement Presentation” below for quantification of gains and losses on Futures Contracts for the three months and six months ended June 30, 2014 and 2013.

	The Company purchases certain of its investment securities in the forward market.  The Company purchases ARM TBA contracts and 15-year TBA contracts from dealers.  ARM TBA contracts are not a frequently-traded security and are generally used to acquire MBS for the portfolio.  15-year TBA contracts are a highly liquid security, and may be physically settled, net settled or traded as an investment.  The Company also has commitments with various mortgage origination companies to purchase their production as it becomes securitized.  Forward purchases do not qualify for trade date accounting and are considered derivatives for financial statement purposes, as described in Note 2.  The net fair value of the forward commitment is reported on the balance sheet as an asset (or liability).  Whether the unrealized gain (or loss) is recognized in net income or other comprehensive income depends on whether or not the commitment has been designated as an accounting hedge, as discussed in Note 2.
	The Company did not have any ARM securities forward purchase commitments as of June 30, 2014 and December 31, 2013.
	15-year TBA contracts may be financed in the dollar roll market.  As demonstrated in the “Financial Statement Presentation” discussion below, income from dollar roll transactions and realized and unrealized gains and losses on TBA contracts are recognized in “Gain (loss) on derivative instruments, net.”
	At June 30, 2014 and December 31, 2013, the Company had the following 15-year TBA dollar roll securities:
	Face				Cost			Fair Market Value			Net Asset (Liability)
30-Jun-14	$	2,850,000			$	2,949,433		$	2,962,617		$	13,184
31-Dec-13	$	600,000			$	632,270		$	627,187		$	(5,083	)
At June 30, 2014 and December 31, 2013, the Company also had estimated purchase commitments with mortgage originators with a net fair value in the amount of $3,755 and ($658), respectively that was recorded in AOCI.

Credit-risk-related Contingent Features
The Company has agreements with its interest rate swap and swaption counterparties that contain a provision where if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender then the Company could also be declared in default on its derivative obligations.
The Company has agreements with certain of its derivative counterparties that contain a provision where if the Company’s GAAP shareholders’ equity declines by a specified percentage over a specified time period, or if the Company fails to maintain a minimum shareholders’ equity threshold, then the Company could be declared in default on its derivative obligations.  The Company also has agreements with several of those counterparties that contain provisions regarding maximum leverage ratios.  The most restrictive of these leverage covenants is that if the Company exceeds a leverage ratio of 10 to 1 then the Company could be declared in default on its derivative obligations with that counterparty.  At June 30, 2014, the Company was in compliance with these requirements.
As of June 30, 2014, the fair value of derivatives in a net liability position related to the agreements described above was $77,583.  The Company has collateral posting requirements with each of its counterparties and all interest rate swap agreements were fully collateralized as of June 30, 2014.

	The Company is externally managed by ACA pursuant to a management agreement (the “Management Agreement”).  All of the Company’s executive officers are also employees of ACA.  ACA manages the Company’s day-to-day operations, subject to the direction and oversight of the Company’s board of directors which includes five independent directors.  The Management Agreement expires on February 23, 2015 and is thereafter automatically renewed for an additional one-year term unless terminated under certain circumstances.  ACA must be provided 180 days prior notice of any such termination and will be paid a termination fee equal to four times the average annual management fee earned by ACA during the two year period immediately preceding termination, calculated as of the end of the most recently completed fiscal quarter prior to the date of termination.
	Under the terms of the Management Agreement, the Company reimburses ACA for certain operating expenses of the Company that are borne by ACA.  ACA is entitled to receive a management fee payable monthly in arrears in an amount equal to 1/12th of an amount determined as follows:
	·	for the Company’s equity up to $250 million, 1.50% (per annum) of equity; plus
	·	for the Company’s equity in excess of $250 million and up to $500 million, 1.10% (per annum) of equity; plus
	·	for the Company’s equity in excess of $500 million and up to $750 million, 0.80% (per annum) of equity; plus
	·	for the Company’s equity in excess of $750 million, 0.50% (per annum) of equity.
	For purposes of calculating the management fee, equity is defined as the value, computed in accordance with GAAP, of shareholders’ equity, adjusted to exclude the effects of unrealized gains or losses.  The following table presents amounts incurred for management fee, reimbursable expenses and share-based compensation expense related to the restricted common shares granted to management.

Basis of Presentation and Use of Estimates	'
	Basis of Presentation and Use of Estimates
	The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.  In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.  Operating results for the three and six months ended June 30, 2014 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2014.  These unaudited consolidated financial statements 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, 2013.
	The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  Significant estimates affecting the accompanying consolidated financial statements include the valuation of agency securities and derivative instruments.
	Certain prior period amounts have been reclassified to conform to the current period presentation.
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and all of its subsidiaries.  The Company also considers the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standard Codification (“ASC”) Topic 810 on Consolidation in determining whether consolidation is appropriate for any interests held in variable interest entities.  All significant intercompany balances and transactions have been eliminated.
Financial Instruments	'
	Financial Instruments
	The Company considers its cash and cash equivalents, restricted cash, agency securities (settled and unsettled), forward purchase commitments, debt security held to maturity, receivable for securities sold, accrued interest receivable, principal payment receivable, payable for unsettled securities, derivative instruments, repurchase agreements, dollar roll liabilities and accrued interest payable to meet the definition of financial instruments.  The carrying amount of cash and cash equivalents, restricted cash, receivable for securities sold, accrued interest receivable, dollar roll liabilities and payable for unsettled securities approximate their fair value due to the short maturities of these instruments and are valued using Level 1 inputs.  The carrying amount of repurchase agreements is deemed to approximate fair value given their short-term duration and would be valued using Level 2 inputs.  See Note 4 and 7 for discussion of the fair value of agency securities and forward purchase commitments, respectively.  See Note 5 for discussion of the fair value of the held to maturity debt security.  See Note 7 for discussion of the fair value of derivative instruments.
	The Company limits its exposure to credit losses on its portfolio of securities by purchasing predominantly agency securities.  The portfolio is diversified to avoid undue exposure to loan originator, geographic and other types of concentration.  The Company manages the risk of prepayments of the underlying mortgages by creating a diversified portfolio with a variety of expected prepayment characteristics.  See Note 4 for additional information on MBS.
	The Company is engaged in various trading and brokerage activities including repurchase agreements, dollar roll transactions, interest rate swap agreements, interest rate swaptions and futures contracts in which counterparties primarily include broker-dealers, banks, and other financial institutions.  In the event counterparties do not fulfill their obligations, the Company may be exposed to risk of loss.  The risk of default depends on the creditworthiness of the counterparty and/or issuer of the instrument.  It is the Company’s policy to review, as necessary, the credit standing for each counterparty.  See Note 6 for additional information on repurchase agreements and Note 7 for additional information on dollar roll transactions, interest rate swap agreements, interest rate swaptions and futures contracts.
Mortgage-Backed Securities	'
	Mortgage-Backed Securities
	The Company invests predominantly in agency securities representing interests in or obligations backed by pools of single-family residential mortgage loans.  Guidance under the FASB ASC Topic 320 on Investments requires the Company to classify its investments as either trading, available-for-sale or held-to-maturity securities.  Management determines the appropriate classifications of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date.  The Company currently classifies all of its agency securities as available-for-sale.  All assets that are classified as available-for-sale are carried at fair value and unrealized gains and losses are included in other comprehensive income (loss).  The estimated fair values of agency securities are determined by management by obtaining valuations for its agency securities from independent sources and averaging these valuations.  Security purchase and sale transactions are recorded on the trade date.  Gains or losses realized from the sale of securities are included in income and are determined using the specific identification method.
	Forward purchase commitments to acquire “when issued” or to-be-announced (“TBA”) securities are recorded at fair value in accordance with ASC Topic 815, Derivatives and Hedging (“ASC 815”).  The fair value of these forward purchase commitments is included in derivative assets or derivative liabilities in the accompanying consolidated balance sheets.  If the Company intends to take physical delivery of the securities, as is the case for forward purchase commitments to acquire TBA securities from mortgage originators, the commitment is designated as an all-in-one cash flow hedge and its unrealized gains and losses are recorded in other comprehensive income.  If the Company does not intend to take physical delivery, as is the case with TBA dollar roll transactions, the commitment is not designated as an accounting hedge and unrealized gains and losses are recorded in “Gain (loss) on derivative instruments, net.” See note 7 for additional information on forward purchase commitments.
	The Company assesses its investment securities for other-than-temporary impairment on at least a quarterly basis.  When the fair value of an investment is less than its amortized cost at the balance sheet date the impairment is designated as either “temporary” or “other-than-temporary.” In deciding on whether or not a security is other than temporarily impaired, the Company uses a two-step evaluation process.  First, the Company determines whether it has made any decision to sell a security that is in an unrealized loss position, or, if not, the Company determines whether it is more likely than not that the Company will be required to sell the security prior to recovering its amortized cost basis.  If the answer to either of these questions is “yes” then the security is considered other-than-temporarily impaired.  No impairment losses were recognized during the periods presented.

	The Company manages economic risks, including interest rate, liquidity and credit risks, primarily by managing the amount, sources, cost, and duration of its debt funding.  The objectives of the Company’s risk management strategy are 1) to attempt to mitigate the risk of the cost of its variable rate liabilities increasing during a period of rising interest rates, and 2) to reduce fluctuations in net book value over a range of interest rate scenarios.  The principal instruments that the Company uses to achieve these objectives are interest rate swaps and Eurodollar Futures Contracts (“Futures Contracts”).  The Company uses Futures Contracts to approximate the economic hedging results achieved with interest rate swaps.  The Company does not enter into any of these transactions for speculative purposes.
	The Company accounts for derivative instruments in accordance with ASC 815, which requires an entity to recognize all derivatives as either assets or liabilities and to measure those instruments at fair value.  The accounting for changes in the fair value of derivative instruments depends on whether the instruments are designated and qualify as part of a hedging relationship pursuant to ASC 815.  Changes in fair value related to derivatives not in hedge designated relationships are recorded in “Gain (loss) on derivative instruments, net” in the Company’s consolidated statements of income, whereas changes in fair value related to derivatives in hedge designated relationships are initially recorded in other comprehensive income (loss) and later reclassified to income at the time that the hedged transactions affect earnings.  Any portion of the changes in fair value due to hedge ineffectiveness is immediately recognized in the income statement.
	Derivative instruments in a gain position are reported as derivative assets and derivative instruments in a loss position are reported as derivative liabilities in the Company’s consolidated balance sheets.  In the Company’s consolidated statements of cash flows, cash receipts and payments related to derivative instruments are classified according to the underlying nature or purpose of the derivative transaction, generally in the operating section if the derivatives are designated as accounting hedges and in the investing section otherwise.  The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts.  The Company attempts to minimize this risk by limiting its counterparties to major financial institutions with acceptable credit ratings, monitoring positions with individual counterparties and adjusting posted collateral as required.
	All of the Company’s interest rate swaps have historically been accounted for as cash flow hedges under ASC 815.  However, on September 30, 2013, the Company discontinued hedge accounting for its interest rate swap agreements by de-designating the interest rate swaps as cash flow hedges.  No interest rate swaps were terminated in conjunction with this action, and the Company’s risk management and hedging practices were not impacted.  As a result of discontinuing hedge accounting, beginning October 1, 2013 changes in the fair value of the Company’s interest rate swap agreements are recorded in “Gain (loss) on derivative instruments, net” in the Company’s consolidated statements of income, rather than in other comprehensive income (loss).  Also, net interest paid or received under the interest rate swaps, which up through September 30, 2013 was recognized in “interest expense,” is instead recognized in “Gain (loss) on derivative instruments, net.” These interest rate swaps continue to be reported as assets or liabilities on the Company’s consolidated balance sheets at their fair value.
	As long as the forecasted transactions that were being hedged (i.e. rollovers of the Company’s repurchase agreement borrowings) are still expected to occur, the balance in accumulated other comprehensive income (AOCI) from interest rate swap activity up through September 30, 2013 will remain in AOCI and be recognized in the Company’s consolidated statements of income as “interest expense” over the remaining term of the interest rate swaps.  See Note 7 for further information.
	The Company may also enter into forward purchase commitments as a means of investing in and financing agency securities via TBA dollar roll transactions.  TBA dollar roll transactions involve moving the settlement of a TBA contract out to a later date by entering into an offsetting short position (referred to as a “pair off”), net settling the paired off positions for cash, and simultaneously purchasing a similar TBA contract for a later settlement date.  The agency securities purchased at the later settlement date are typically priced at a discount to securities for settlement in the current month.  This difference is referred to as the “price drop.” The price drop represents compensation to the Company for foregoing net interest margin (interest income less repurchase agreement financing cost) and is referred to as “dollar roll income,” which the Company classifies in “Gain (loss) on derivative instruments, net.” Realized and unrealized gains and losses related to TBA dollar roll transactions are also recognized in “Gain (loss) on derivative instruments, net.” TBA dollar roll transactions represent off-balance sheet financing.
Repurchase Agreements	'
	Repurchase Agreements
	The Company finances the acquisition of its agency securities through the use of repurchase agreements.  Under these repurchase agreements, the Company sells securities to a lender and agrees to repurchase the same securities in the future for a price that is higher than the original sales price.  The difference between the sale price that the Company receives and the repurchase price that the Company pays represents interest paid to the lender.  Although structured as a sale and repurchase obligation, a repurchase agreement operates as a financing 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 records repurchase agreements on the consolidated balance sheets at the amount of cash received (or contract value), with accrued interest recorded separately.  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 such agreement at the then prevailing financing rate.  These repurchase agreements may require the Company to pledge additional assets to the lender in the event the estimated fair value of the existing pledged collateral declines.
Dollar Roll Liability	'
	Dollar Roll Liability
	In addition to the TBA dollar roll transactions described above, the Company may from time to time execute dollar roll transactions on agency securities (“CUSIP dollar rolls”).  These transactions represent on-balance sheet financing, presented as “Dollar roll liability” in the Company’s consolidated balance sheets.  During the period of a CUSIP dollar roll, the financed security remains on the Company’s balance sheet, and the components of the net interest margin earned from the price drop are classified in “interest income on mortgage-backed securities” and “interest expense,” respectively.
Offsetting of Assets and Liabilities	'
	Offsetting of Assets and Liabilities
	The Company’s derivative agreements and repurchase agreements generally contain provisions that allow for netting or the offsetting of receivables and payables with each counterparty.  The Company reports amounts in its consolidated balance sheets on a gross basis without regard for such rights of offset or master netting arrangements.
Interest Income	'
	Interest Income
	Interest income is earned and recognized based on the outstanding principal amount of the investment securities and their contractual terms.  Premiums and discounts associated with the purchase of the investment securities are amortized or accreted into interest income over the actual lives of the securities using the effective interest method.
Income Taxes	'
	Income Taxes
	The Company has elected to be taxed as a REIT under the Code.  The Company will generally not be subject to federal income tax to the extent that it distributes 100% of its taxable income, after application of available tax attributes, within the time limits prescribed by the Code and as long as it satisfies the ongoing REIT requirements including meeting certain asset, income and stock ownership tests.  The Company has made an election to treat certain of its subsidiaries as TRSs.  These TRSs are taxable as domestic C corporations and are subject to federal, state and local income taxes based upon their taxable income.
Share-Based Compensation	'
	Share-Based Compensation
	Share-based compensation is accounted for under the guidance included in the ASC Topic on Stock Compensation.  For share and share-based awards issued to employees, a compensation charge is recorded in earnings based on the fair value of the award.  For transactions with non-employees in which services are performed in exchange for the Company’s common stock or other equity instruments, the transactions are recorded on the basis of the fair value of the service received or the fair value of the equity instruments issued, whichever is more readily measurable at the date of issuance.  The Company’s share-based compensation transactions resulted in compensation expense of $842 and $627 for the three months ended June 30, 2014 and 2013, respectively.  Share-based compensation expense was $1,702 and $1,256 for the six months ended June 30, 2014 and 2013, respectively.
Earnings Per Common Share (EPS)	'
	Earnings Per Common Share (EPS)
	Basic EPS is computed by dividing net income less preferred stock dividends to arrive at net income available to holders of common stock by the weighted average number of shares of common stock outstanding during the period.  Diluted EPS is computed using the two class method, as described in the ASC Topic on Earnings Per Share, which takes into account certain adjustments related to participating securities.  Participating securities are unvested share-based awards that contain rights to receive nonforfeitable dividends, such as those awarded under the Company’s equity incentive plan.  Net income available to holders of common stock after deducting dividends on unvested participating securities if antidilutive, is divided by the weighted average shares of common stock and common equivalent shares outstanding during the period.  For the diluted EPS calculation, common equivalent shares outstanding includes the weighted average number of shares of common stock outstanding adjusted for the effect of dilutive unexercised stock options, if any.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing: Repurchase-to-Maturity Transaction, Repurchase Financings, and Disclosures (the ASU).  This guidance requires repurchase-to-maturity transactions to be accounted for as secured borrowings as if the transferor retains effective control, even though the transferred financial assets are not returned to the transferor at settlement. The ASU also eliminates existing guidance for repurchase financings and requires instead that entities consider the initial transfer and the related repurchase agreement separately when applying the derecognition requirements of ASC 860, Transfers and Servicing. New disclosures will be required for (1) certain transactions accounted for as secured borrowings and (2) transfers accounted for as sales when the transferor also retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction.  This guidance will take effect for periods beginning after December 15, 2014, and early adoption is prohibited.  Certain disclosures under this guidance do not take effect until the first period beginning after March 15, 2015.  The Company is currently assessing the impact of this guidance.

Schedule of Location of Derivatives Instruments on Consolidated Balance Sheet	'
	The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts).  The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.  The fair value of interest rate swaptions is based on third party broker quotations that are non binding bids to trade.  The fair value of Futures Contracts is based on quoted prices from the exchange on which they trade.  The fair value of forward purchase commitments was determined using the same methodology as agency securities as described in Note 4.  The table below presents the fair value of the Company’s derivative instruments as well as their classification on the consolidated balance sheets as of June 30, 2014 and December 31, 2013, respectively.
