Organization Consolidation And Presentation Of Financial Statements [Abstract]
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 in single-family residential mortgage assets, such as mortgage-backed securities (“MBS”), and other financial assets. To date, the Company has primarily invested in adjustable-rate (“ARMs”) and fixed rate MBS, issued or guaranteed by a U.S. Government agency, such as Ginnie Mae, or by a U.S. Government-sponsored entity, such as Fannie Mae and Freddie Mac (“agency securities”). The Company is externally managed and advised by its manager, 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. On August 31, 2015, the Company closed on its acquisition of Pingora Asset Management, LLC (“PAM”) and Pingora Loan Servicing, LLC (“PLS,” and together, “Pingora”), a specialized asset manager focused on investing in new-production performing mortgage servicing rights (“MSR”) and master-servicing residential mortgage loans sourced primarily from direct, ongoing relationships with loan originators. PAM is a registered investment advisor and PLS is an approved servicer with Fannie Mae, Freddie Mac and Ginnie Mae that is managed by PAM. The acquisition provides the Company with MSR portfolio management and master-servicing oversight capabilities to the Company, accelerating the Company’s entry into investing in MSR (see Note 6 for further discussion). In addition to being an income-producing investment, the Company expects that MSR will serve as a natural hedge against the impact of changes in interest rates on the fair value of the Company’s MBS portfolio. The Company acquired 100% of the voting interests of Pingora for cash consideration of approximately $23.5 million. In conjunction with the transaction, the Company also issued approximately $4.4 million of equity interests to Pingora management, a significant portion of which is subject to future vesting. The Company has accounted for the transaction as a business combination in accordance with ASC 805, Business Combination The opening balance sheet of Pingora as of the acquisition date consisted of the following assets and liabilities: Assets / (Liabilities) Mortgage loans held for sale, at fair value $ 4,292 Cash and cash equivalents 1,937 Ascent software platform 2,000 Customer relationships intangible 16,000 Licenses 2,000 Goodwill 3,498 Warehouse lines of credit (3,989 ) Deferred tax liabilities (2,060 ) Other net liabilities (215 ) $ 23,463 The acquisition is subject to certain post-closing adjustments and the Company’s allocation of the purchase price to the assets and liabilities acquired may be adjusted accordingly.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	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 nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2015. 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, 2014. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of 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 MBS and derivative instruments. Certain prior period amounts have been reclassified to conform to the current period classification. 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. PLS has been determined to be a variable interest entity (“VIE”) pursuant to ASC 810, Consolidation The following table presents the assets and liabilities of PLS that have been included in the Company’s consolidated balance sheets: September 30, 2015 Mortgage loans held for sale $ 9,572 Mortgage servicing rights 170,447 Cash and cash equivalents 20,547 Accrued interest receivable 19 Other assets 18,983 Total assets $ 219,568 Accounts payable and other liabilities $ 16,776 Warehouse lines of credit 8,709 Derivative liabilities 41 Total liabilities $ 25,526 Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The carrying amounts of cash equivalents approximate their fair value. Cash and cash equivalents includes pledged cash held in margin accounts at various counterparties as collateral on interest rate swaps, Eurodollar futures contracts and forward commitments to purchase TBA securities (as defined below). Financial Instruments The Company considers its cash and cash equivalents, MBS (settled and unsettled), mortgage loans, forward purchase commitments, debt security held-to-maturity, receivable for securities sold, accrued interest receivable, principal payments receivable, payable for unsettled securities, derivative instruments, borrowings and accrued interest payable to meet the definition of financial instruments. The carrying amount of cash and cash equivalents, receivable for securities sold, accrued interest receivable and payable for unsettled securities approximate their fair value due to the short maturities of these instruments and would be valued using Level 1 inputs. The carrying amount of borrowings are deemed to approximate fair value given their short-term duration and would be valued using Level 2 inputs. See Note 4 for discussion of the fair value of MBS. See Note 5 for discussion of the fair value of mortgage loans. See Note 7 for discussion of the fair value of the held-to-maturity debt security. See Note 9 for discussion of the fair value of derivative instruments, including forward purchase commitments. See Note 3 for a summary of all the Company’s financial instruments. The Company limits its exposure to credit losses on its portfolio of securities by purchasing predominantly agency securities. The Company’s investments are 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 and retain collateral when appropriate. See Note 8 for additional information on repurchase agreements and Note 9 for additional information on dollar roll transactions, interest rate swap agreements, interest rate swaptions and futures contracts. Mortgage-Backed Securities The Company invests in MBS representing interests in or obligations backed by pools of single-family residential mortgage loans. Other than securities for which the fair value option is elected, GAAP requires the Company to classify its investment securities 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. Other than its investments in credit risk transfer bonds issued by Fannie Mae and Freddie Mac (“GSE CRT bonds”), the Company currently classifies all of its MBS as available-for-sale. All MBS 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 Company accounts for its GSE CRT bonds under the fair value option. Under the fair value option, these bonds are carried at fair value and unrealized gains and losses are included in “Net unrealized loss on mortgage backed securities” in the consolidated statements of income. All the Company’s security purchase and sale transactions are recorded on the trade date. Gains or losses realized from the sale of securities are included in “Net realized gain on sale of mortgage-backed securities” in the consolidated statements of 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 of the securities, as is the case with most TBA dollar roll transactions, the commitment is not designated as an accounting hedge and unrealized gains and losses are recorded in “Loss on derivative instruments, net.” See Note 9 for additional information on forward purchase commitments. The Company assesses its available-for-sale 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 other-than temporary impairments were recognized during the periods presented herein. Mortgage Loans Held for Investment The Company purchases individual prime jumbo adjustable-rate whole mortgage loans with the intention of holding them as investments. In order to finance its investment in the loans, the Company may securitize the loans into MBS not issued or guaranteed by a U.S. Government agency or U.S. Government-sponsored entity. The Company would then purchase the majority of the MBS that the securitization trusts would issue, and would expect to consolidate the trusts pursuant to GAAP. The Company has elected to account for these loans under the fair value option, pursuant to ASC Topic 825. As a result of electing the fair value option, the mortgage loans are carried at fair value with changes therein reflected in consolidated net income (loss), consistent with the accounting for the related hedging instruments, thereby enhancing the usefulness of the Company’s financial statements. See “Interest Income” below for discussion of the recognition of interest income on mortgage loans. Other changes in fair value are reported in “Net gain on mortgage loans” in the consolidated statements of income. Given the Company’s intent to hold the mortgage loans as investments, purchases and sales or paydowns of mortgage loans held for investment are classified as investing cash flows in the consolidated statements of cash flows. Mortgage Loans Held for Sale The Company purchases certain individual whole mortgage loans with the intention of selling them to Ginnie Mae for inclusion in securitizations. The Company has elected to account for these loans under the fair value option, pursuant to ASC Topic 825, because it better reflects the short-term nature of the Company’s holdings in these loans. As a result of electing the fair value option, the mortgage loans are carried at fair value with changes therein reflected in consolidated net income (loss). See “Interest Income” below for discussion of the recognition of interest income on mortgage loans. Other changes in fair value are reported in “Net gain on mortgage loans” in the consolidated statements of income. Mortgage Servicing Rights The Company purchases MSR with the intention of holding them as investments. The Company and its subsidiaries do not originate or directly service mortgage loans. Rather, it utilizes duly licensed subservicers to perform substantially all servicing functions for the loans underlying the MSR. The Company has elected to account for its investments in MSR at fair value pursuant to ASC 860, Transfers and Servicing. As a result, MSR are carried at fair value with changes therein reported in “Net loss on mortgage servicing rights” in the consolidated statements of income. Servicing fee income and expense are reported on a net basis in “Net mortgage servicing rights income” in the consolidated statements of income. 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, measured 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 “Net gain (loss) on derivative instruments” 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 in an asset position 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. 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 “Net gain (loss) on derivative instruments” 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 “Net gain (loss) on derivative instruments.” 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 remains in AOCI and is recognized in the Company’s consolidated statements of income as “interest expense” over the remaining term of the interest rate swaps. See Note 9 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 “Net gain (loss) on derivative instruments.” Realized and unrealized gains and losses related to TBA dollar roll transactions are also recognized in “Net gain (loss) on derivative instruments.” TBA dollar roll transactions represent off-balance sheet financing. Repurchase Agreements The Company finances the acquisition of its MBS primarily 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. Warehouse Lines of Credit Warehouse lines of credit include borrowings under mortgage loan warehouse facilities with various counterparties that expire within one year. These borrowings are collateralized by mortgage loans. If the value of the underlying collateral (as determined by the counterparty) securing these borrowings decreases, the Company may be subject to margin calls during the period the borrowing is outstanding. To satisfy these margin calls, the Company may have to pledge additional collateral or repay portions of the borrowings. Federal Home Loan Bank Advances During the third quarter of 2015, a wholly-owned subsidiary of the Company became a member of the Federal Home Loan Bank of Atlanta (the “FHLB”). The FHLB offers a variety of products and services, including short-term and long-term secured advances. FHLB advances are carried at their contractual amounts. 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 on MBS 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. The Company recognizes interest income on mortgage loans held based on their stated coupon rates. If a loan becomes 90 days past due, it is considered non-performing and is placed in non-accrual status; accrual of interest income ceases and any existing interest receivables are reversed. Any cash received while a loan is in non-accrual status is first applied to unpaid principal and then to unpaid interest. In general, non-performing loans are only restored to accrual status when no principal or interest remains due and unpaid. 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 $966 and $890 for the three months ended September 30, 2015 and 2014, respectively. Share-based compensation expense was $3,045 and $2,592 for the nine months ended September 30, 2015 and 2014, 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. Other Comprehensive Income (Loss) Other comprehensive income refers to revenue, expenses, gains, and losses that are recorded directly as an adjustment to shareholders’ equity. Other comprehensive income for the Company generally arises from unrealized gains or losses generated from changes in market values of available-for-sale securities and derivative instruments that have been designated as accounting hedges.

Fair Value Disclosures [Abstract]
Fair Value Measurements	3. Financial Value Measurements 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. The Company’s Futures Contracts were valued using Level 1 inputs. The Company’s MBS, mortgage loans held for sale and derivatives other than Futures Contracts were valued using Level 2 inputs. Mortgage loans held for investment along with related purchase commitments and MSR were valued using Level 3 inputs. See Notes 4, 5, 6 and 9, respectively, for a discussion of the valuation of MBS, mortgage loans, MSR and derivatives. The carrying values and fair values of assets and liabilities that are required to be reported or disclosed at fair value as of September 30, 2015 and December 31, 2014 were as follows.

Available-for-sale MBS
Mortgage-Backed Securities	4. Mortgage-Backed Securities All of the Company’s MBS, other than GSE CRT bonds, are classified as available-for-sale and, as such, are reported at their estimated fair value. The GSE CRT bonds are accounted for under the fair value option as discussed in Note 2. The MBS market is primarily an over-the-counter market. As such, there are no standard, public market quotations for individual MBS. The Company estimates the fair value of its MBS based on a market approach by obtaining values for its securities from third-party pricing services. 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. The Company regularly reviews the prices obtained and the methods used to derive those prices. As part of this evaluation, the Company considers security-specific 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’s analysis of pricing information obtained also includes comparing the data received to other available information, such as 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. In addition to agency securities, the Company’s MBS portfolio includes MBS not issued or guaranteed by a U.S. Government agency or a U.S. Government-sponsored entity (“non-agency securities”) and GSE CRT bonds.

The unrealized losses on the above securities are the result of market interest rates and are not considered to be credit related. No impairment losses were recognized during the periods presented herein. The contractual maturity of the Company’s MBS ranges from 15 to 30 years. Because of prepayments on the underlying mortgage loans, the actual weighted-average life is expected to be significantly less than the stated maturity.

Mortgage Loans Mortgage Loans Held for Investment The Company purchases individual jumbo adjustable-rate whole mortgage loans with the intention of holding them as investments. The loans are being accounted for under the fair value option. See Note 2 for further discussion. As of September 30, 2015, the unpaid principal balance and the fair value of the Company’s mortgage loans held for investment were $259,165 and $265,281, respectively. As of December 31, 2014, the unpaid principal balance and the fair value of the Company’s mortgage loans held for investment were $30,792 and $31,460, respectively. The Company did not invest in mortgage loans prior to the fourth quarter of 2014. The following table provides the geographic distribution of mortgage loans held for investment at September 30, 2015 and December 31, 2014, based on unpaid principal balance.

The Company classifies its mortgage loans held for investment as Level 3 in the fair value hierarchy. Prices for these instruments are obtained from third-party pricing providers which use significant unobservable inputs in their valuations. These valuations are prepared on an instrument-by-instrument basis and primarily use discounted cash flow models that include unobservable market data inputs including prepayment rates, delinquency levels, and credit losses. Model valuations are then compared to external indicators such as market price quotations from market makers for similar instruments and recent transactions in the same or similar instruments. These valuations may also be discounted to reflect illiquidity and/or non-transferability, with the amount of such discount estimated by the third-party pricing provider in the absence of market information. The valuation of mortgage loans held for investment requires significant judgment by the third-party pricing provider and management. Assumptions used by the third-party pricing provider due to lack of observable inputs may significantly impact the resulting fair value and therefore the Company’s financial statements. Management reviews the valuations received from the third-party pricing provider. As part of this review, prices are compared against other pricing along with internal valuation expertise to ensure assumptions and pricing is reasonable. The following table provides information about the significant unobservable inputs used in the Level 3 valuation of the Company’s mortgage loans held for investment at September 30, 2015 and December 31, 2014. September 30, 2015 December 31, 2014 Weighted- Weighted- Unobservable Input Range Average Range Average Discount rate 2.0% - 3.3% 3.1 % 3.6% - 3.9% 3.8 % Conditional refinance rate 12.8% - 21.1% 16.4 % 12.4% - 19.3% 15.3 % Default rate 0% - 2.6% 0.6 % 0% - 1.5% 0.4 % Loss severity 0% - 25.6% 15.2 % 10.2% - 19.9% 13.8 % Mortgage Loans Held for Sale The Company purchases individual whole mortgage loans with the intention of selling them to Ginnie Mae for inclusion in securitizations. As of September 30, 2015, the unpaid principal balance and the fair value of the Company’s mortgage loans held for sale were $9,493 and $9,572, respectively. The Company did not invest in mortgage loans held for sale prior to the acquisition of Pingora on August 31, 2015. The Company classifies its mortgage loans held for sale as Level 2 in the fair value hierarchy. Prices for these instruments are obtained from third-party pricing providers and other applicable market data. If observable market prices are not available or insufficient to determine fair value due principally to illiquidity in the marketplace, then fair value is based upon cash flow models that are primarily based on observable market-based inputs but also include unobservable market data inputs, including prepayment speeds, delinquency levels, and credit losses.

Prices for these instruments are obtained from internal models and third-party pricing providers, both of which use significant unobservable inputs in their valuations. These valuations are prepared on an instrument-by-instrument basis and primarily use discounted cash flow models that include unobservable market data inputs including prepayment rates, delinquency levels, and discount rates. Model valuations are then compared to external indicators such as market price quotations from market makers for similar instruments and recent transactions in the same or similar instruments. These valuations may also be discounted to reflect illiquidity and/or non-transferability, with the amount of such discount estimated by the third-party pricing provider in the absence of market information. The valuation of MSR requires significant judgment by management and the third-party pricing provider. Assumptions used for which there is a lack of observable inputs may significantly impact the resulting fair value and therefore the Company’s financial statements. Management reviews the valuations received from the third-party pricing provider and uses them as a point of comparison to its internally modeled values. As part of this review, prices are compared against other pricing indicators to ensure assumptions and pricing are reasonable. The following table provides information about the significant unobservable inputs used in the Level 3 valuation of the Company’s MSR at September 30, 2015 and December 31, 2014. September 30, 2015 December 31, 2014 Weighted- Weighted- Unobservable Input Range Average Range Average Discount rate 10.0% - 11.0% 10.3 % - - Prepayment rate 8.5% - 36.1% 11.1 % - - Delinquency rate 0% - 1.3% 0.7 % - - The Company’s mortgage servicing income and mortgage servicing expenses were as follows for the three and nine months ended September 30, 2015 and 2014.

The Company’s investment in MBS mitigates the impact of such a decline on the Company’s total portfolio as a decline in interest rates generally leads to an increase in the value of the Company’s MBS.

Other Investments	7. Other Investments Other investments consisted of the following items as of September 30, 2015 and December 31, 2014: September 30, 2015 December 31, 2014 Short-term investments $ 30,444 $ 20,252 Debt security, held-to-maturity 15,000 15,000 Equity investments 6,603 6,000 Total other investments $ 52,047 $ 41,252 The Company owns both a $15,000 debt security and a $6,000 equity investment in a non-public repurchase lending counterparty. The debt security matures on March 24, 2019. The Company has designated this debt security as a held-to-maturity investment, and as such it is carried at its cost basis. The debt security pays interest quarterly at the rate of 4.0% above the three-month London Interbank Offered Rate (“LIBOR”). The Company estimates the fair value of this debt security to be approximately $14,620 and $14,853 at September 30, 2015 and December 31, 2014, respectively, which was determined by calculating the present value of the projected future cash flows using a discount rate from a similar issuer and security (which represent Level 2 inputs). The Company accounts for the equity investment in the non-public repurchase lending counterparty under the cost method and concluded there have been no identified events or circumstances that would have a significant adverse effect on the fair value of the investment since the purchase date. As a member of the FHLB, the Company also has an equity investment of $603 in FHLB. The amount of investment required is partially dependent on the level of advances taken. This investment is accounted for under the cost method, because the stock can only be sold at its par value, and only to the FHLB.

Banking And Thrift [Abstract]
Borrowings	8. Borrowings The Company uses repurchase agreements and FHLB advances to finance MBS purchases. Repurchase agreements and FHLB advances are collateralized by the Company’s MBS and typically bear interest at rates that are closely related to LIBOR. At September 30, 2015 and December 31, 2014, the Company had repurchase indebtedness outstanding with 26 and 25 counterparties with a weighted average remaining contractual maturity of 0.9 and 1.0 months, respectively. The following table presents contractual maturity information regarding the Company’s repurchase agreements: September 30, 2015 December 31, 2014 Weighted Average Weighted Average Balance Contractual Rate Balance Contractual Rate Within 30 days $ 12,990,809 0.44 % $ 13,770,099 0.35 % 30 days to 3 months 250,000 0.52 % 1,489,732 0.36 % 3 months to 36 months 1,000,000 0.59 % 500,000 0.53 % $ 14,240,809 0.46 % $ 15,759,831 0.36 % The fair value of securities and accrued interest the Company had pledged under repurchase agreements at September 30, 2015 and December 31, 2014 was $14,936,324 and $16,575,106, respectively. As of September 30, 2015, the Company had $14,132 in advances outstanding with the FHLB at a borrowing rate of 0.2% with a maturity date of October 2015. The advances are secured by the pledge of agency MBS with a fair value of $15,714. The Company’s aggregate borrowing capacity with the FHLB is $1 billion. The Company has access to warehouse lines of credit with three financial institutions to finance purchases of whole mortgage loans. Borrowings under these facilities are charged interest at a specified margin over the one-month LIBOR interest rate. At September 30, 2015, the Company has outstanding borrowings with two counterparties totaling $33,172 with maturity dates between November 2015 and March 2016. The Company has pledged mortgage loans with a fair value of $37,407 as collateral pursuant to these lines of credit. The borrowing limit under these lines of credit is $300 million. See Notes 2 and 9 for discussion of TBA dollar roll transactions, which represent off-balance sheet financing.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Other Hedging Instruments	9 . 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 values of interest rate swaptions are estimated based on the fair value of the underlying interest rate swaps that the Company has the option to enter, and are based on estimates from the counterparty and pricing models. The fair value of Futures Contracts is based on quoted prices from the exchange on which they trade. The fair value of MBS forward purchase commitments was determined using the same methodology as MBS as described in Note 4. The fair value of forward purchase commitments for whole loans was determined using the same methodology as mortgage loans held for investment as described in Note 5. The Company applies fallout assumptions to the third-party pricing of forward purchase commitments in order to adjust for loans that the counterparties may not successfully issue. 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 September 30, 2015 and December 31, 2014, respectively. Derivative Instruments Balance Sheet Location September 30, 2015 December 31, 2014 Interest rate swaps and swaptions Derivative assets $ 1,831 $ 11,050 Forward purchase commitments - MBS Derivative assets 2,109 16,101 Forward purchase commitments - mortgage loans Derivative assets 425 - $ 4,365 $ 27,151 Interest rate swaps Derivative liabilities $ 22,964 $ 42,052 Futures contracts Derivative liabilities 394,221 202,501 Forward purchase commitments - MBS Derivative liabilities 1,736 36 Forward purchase commitments - mortgage loans Derivative liabilities - 2 $ 418,921 $ 244,591 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 agreements 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 AOCI 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 and nine months 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 $4,842 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 “Net gain (loss) on derivative instruments” 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 “Net gain (loss) on derivative instruments” beginning October 1, 2013. The volume of activity for the Company’s interest rate swap instruments is shown in the table below.

Eurodollar Futures Contracts The Company uses Futures Contracts to 1) synthetically replicate an interest rate swap, or 2) offset the changes in value of its forward purchases of certain MBS and mortgage loans. The following table presents the composition of the Company’s Futures Contracts as of September 30, 2015 and December 31, 2014, respectively. Fair Value September 30, 2015 December 31, 2014 Futures Contracts designed to replicate swaps $ (386,267 ) $ (202,202 ) Futures Contracts designed to hedge value changes in forward purchases (7,954 ) (299 ) Total fair value of Futures Contracts $ (394,221 ) $ (202,501 ) The volume of activity for the Company’s Futures Contracts is shown in the table below.

The effective dates of the Eurodollar contracts underlying the Company’s Futures Contracts range from 2015 through 2022. 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 net income 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 and nine months To Be Announced Securities Purchases and Mortgage Loan Commitments 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. 15-year TBA contracts may also be financed in the dollar roll market. 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 following table summarizes the Company’s forward purchase commitments as of September 30, 2015.

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. At September 30, 2015, the Company was in compliance with these requirements. As of September 30, 2015, the fair value of derivatives in a net liability position related to these agreements was $22,964. The Company has collateral posting requirements with each of its counterparties and all interest rate swap agreements were fully collateralized as of September 30, 2015.

Related Party Transactions [Abstract]
Transactions with Related Parties	12. Transactions with Related Parties Management Fees 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 six independent directors. The Management Agreement expires on February 23, 2016 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. Three Months Ended September 30 Nine Months Ended September 30 2015 2014 2015 2014 Management fee $ 4,037 $ 4,122 $ 12,215 $ 12,420 Reimbursable expenses 1,124 715 3,681 2,403 Total $ 5,161 $ 4,837 $ 15,896 $ 14,823 Share-based compensation $ 966 $ 890 $ 3,045 $ 2,592 None of the reimbursement payments were specifically attributable to the compensation of the Company’s executive officers. Reimbursable expenses above includes rent paid by ACA for the Company’s office space. As of October 2014, the Company’s office space is rented from a real estate partnership in which some of the Company’s executive officers have a financial interest, at an annual rate of approximately $300. At September 30, 2015 and December 31, 2014, the Company owed ACA $1,947 and $3,198, respectively, for the management fee and reimbursable expenses, which is included in accounts payable and other liabilities.

Summary of Significant Accoun21

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2015
Accounting Policies [Abstract]
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 nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2015. 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, 2014. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of 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 MBS and derivative instruments. Certain prior period amounts have been reclassified to conform to the current period classification.
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. PLS has been determined to be a variable interest entity (“VIE”) pursuant to ASC 810, Consolidation The following table presents the assets and liabilities of PLS that have been included in the Company’s consolidated balance sheets: September 30, 2015 Mortgage loans held for sale $ 9,572 Mortgage servicing rights 170,447 Cash and cash equivalents 20,547 Accrued interest receivable 19 Other assets 18,983 Total assets $ 219,568 Accounts payable and other liabilities $ 16,776 Warehouse lines of credit 8,709 Derivative liabilities 41 Total liabilities $ 25,526
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The carrying amounts of cash equivalents approximate their fair value. Cash and cash equivalents includes pledged cash held in margin accounts at various counterparties as collateral on interest rate swaps, Eurodollar futures contracts and forward commitments to purchase TBA securities (as defined below).
Financial Instruments	Financial Instruments The Company considers its cash and cash equivalents, MBS (settled and unsettled), mortgage loans, forward purchase commitments, debt security held-to-maturity, receivable for securities sold, accrued interest receivable, principal payments receivable, payable for unsettled securities, derivative instruments, borrowings and accrued interest payable to meet the definition of financial instruments. The carrying amount of cash and cash equivalents, receivable for securities sold, accrued interest receivable and payable for unsettled securities approximate their fair value due to the short maturities of these instruments and would be valued using Level 1 inputs. The carrying amount of borrowings are deemed to approximate fair value given their short-term duration and would be valued using Level 2 inputs. See Note 4 for discussion of the fair value of MBS. See Note 5 for discussion of the fair value of mortgage loans. See Note 7 for discussion of the fair value of the held-to-maturity debt security. See Note 9 for discussion of the fair value of derivative instruments, including forward purchase commitments. See Note 3 for a summary of all the Company’s financial instruments. The Company limits its exposure to credit losses on its portfolio of securities by purchasing predominantly agency securities. The Company’s investments are 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 and retain collateral when appropriate. See Note 8 for additional information on repurchase agreements and Note 9 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 in MBS representing interests in or obligations backed by pools of single-family residential mortgage loans. Other than securities for which the fair value option is elected, GAAP requires the Company to classify its investment securities 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. Other than its investments in credit risk transfer bonds issued by Fannie Mae and Freddie Mac (“GSE CRT bonds”), the Company currently classifies all of its MBS as available-for-sale. All MBS 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 Company accounts for its GSE CRT bonds under the fair value option. Under the fair value option, these bonds are carried at fair value and unrealized gains and losses are included in “Net unrealized loss on mortgage backed securities” in the consolidated statements of income. All the Company’s security purchase and sale transactions are recorded on the trade date. Gains or losses realized from the sale of securities are included in “Net realized gain on sale of mortgage-backed securities” in the consolidated statements of 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 of the securities, as is the case with most TBA dollar roll transactions, the commitment is not designated as an accounting hedge and unrealized gains and losses are recorded in “Loss on derivative instruments, net.” See Note 9 for additional information on forward purchase commitments. The Company assesses its available-for-sale 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 other-than temporary impairments were recognized during the periods presented herein.
Mortgage Loans Held for Investment	Mortgage Loans Held for Investment The Company purchases individual prime jumbo adjustable-rate whole mortgage loans with the intention of holding them as investments. In order to finance its investment in the loans, the Company may securitize the loans into MBS not issued or guaranteed by a U.S. Government agency or U.S. Government-sponsored entity. The Company would then purchase the majority of the MBS that the securitization trusts would issue, and would expect to consolidate the trusts pursuant to GAAP. The Company has elected to account for these loans under the fair value option, pursuant to ASC Topic 825. As a result of electing the fair value option, the mortgage loans are carried at fair value with changes therein reflected in consolidated net income (loss), consistent with the accounting for the related hedging instruments, thereby enhancing the usefulness of the Company’s financial statements. See “Interest Income” below for discussion of the recognition of interest income on mortgage loans. Other changes in fair value are reported in “Net gain on mortgage loans” in the consolidated statements of income. Given the Company’s intent to hold the mortgage loans as investments, purchases and sales or paydowns of mortgage loans held for investment are classified as investing cash flows in the consolidated statements of cash flows.
Mortgage Loans Held for Sale	Mortgage Loans Held for Sale The Company purchases certain individual whole mortgage loans with the intention of selling them to Ginnie Mae for inclusion in securitizations. The Company has elected to account for these loans under the fair value option, pursuant to ASC Topic 825, because it better reflects the short-term nature of the Company’s holdings in these loans. As a result of electing the fair value option, the mortgage loans are carried at fair value with changes therein reflected in consolidated net income (loss). See “Interest Income” below for discussion of the recognition of interest income on mortgage loans. Other changes in fair value are reported in “Net gain on mortgage loans” in the consolidated statements of income.
Mortgage Servicing Rights	Mortgage Servicing Rights The Company purchases MSR with the intention of holding them as investments. The Company and its subsidiaries do not originate or directly service mortgage loans. Rather, it utilizes duly licensed subservicers to perform substantially all servicing functions for the loans underlying the MSR. The Company has elected to account for its investments in MSR at fair value pursuant to ASC 860, Transfers and Servicing. As a result, MSR are carried at fair value with changes therein reported in “Net loss on mortgage servicing rights” in the consolidated statements of income. Servicing fee income and expense are reported on a net basis in “Net mortgage servicing rights income” in the consolidated statements of income.
Derivative Instruments	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, measured 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 “Net gain (loss) on derivative instruments” 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 in an asset position 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. 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 “Net gain (loss) on derivative instruments” 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 “Net gain (loss) on derivative instruments.” 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 remains in AOCI and is recognized in the Company’s consolidated statements of income as “interest expense” over the remaining term of the interest rate swaps. See Note 9 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 “Net gain (loss) on derivative instruments.” Realized and unrealized gains and losses related to TBA dollar roll transactions are also recognized in “Net gain (loss) on derivative instruments.” TBA dollar roll transactions represent off-balance sheet financing.
Repurchase Agreements	Repurchase Agreements The Company finances the acquisition of its MBS primarily 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.
Warehouse Line Of Credit	Warehouse Lines of Credit Warehouse lines of credit include borrowings under mortgage loan warehouse facilities with various counterparties that expire within one year. These borrowings are collateralized by mortgage loans. If the value of the underlying collateral (as determined by the counterparty) securing these borrowings decreases, the Company may be subject to margin calls during the period the borrowing is outstanding. To satisfy these margin calls, the Company may have to pledge additional collateral or repay portions of the borrowings.
Federal Home Loan Bank Advances	Federal Home Loan Bank Advances During the third quarter of 2015, a wholly-owned subsidiary of the Company became a member of the Federal Home Loan Bank of Atlanta (the “FHLB”). The FHLB offers a variety of products and services, including short-term and long-term secured advances. FHLB advances are carried at their contractual amounts.
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 on MBS 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. The Company recognizes interest income on mortgage loans held based on their stated coupon rates. If a loan becomes 90 days past due, it is considered non-performing and is placed in non-accrual status; accrual of interest income ceases and any existing interest receivables are reversed. Any cash received while a loan is in non-accrual status is first applied to unpaid principal and then to unpaid interest. In general, non-performing loans are only restored to accrual status when no principal or interest remains due and unpaid.
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 $966 and $890 for the three months ended September 30, 2015 and 2014, respectively. Share-based compensation expense was $3,045 and $2,592 for the nine months ended September 30, 2015 and 2014, 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.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) Other comprehensive income refers to revenue, expenses, gains, and losses that are recorded directly as an adjustment to shareholders’ equity. Other comprehensive income for the Company generally arises from unrealized gains or losses generated from changes in market values of available-for-sale securities and derivative instruments that have been designated as accounting hedges.

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 values of interest rate swaptions are estimated based on the fair value of the underlying interest rate swaps that the Company has the option to enter, and are based on estimates from the counterparty and pricing models. The fair value of Futures Contracts is based on quoted prices from the exchange on which they trade. The fair value of MBS forward purchase commitments was determined using the same methodology as MBS as described in Note 4. The fair value of forward purchase commitments for whole loans was determined using the same methodology as mortgage loans held for investment as described in Note 5. The Company applies fallout assumptions to the third-party pricing of forward purchase commitments in order to adjust for loans that the counterparties may not successfully issue. 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 September 30, 2015 and December 31, 2014, respectively.

Components of Accumulated Other Comprehensive Income	The Company records unrealized gains and losses on its MBS and its forward purchase commitments securities as described in Note 4 and Note 9. As discussed in Note 9, the Company ceased hedge accounting for its interest rate swaps effective September 30, 2013. Beginning October 1, 2013, changes in the fair value of interest rate swaps are recorded directly to net income. The cumulative unrealized loss on interest rate swaps in AOCI as of September 30, 2013 is being amortized to net income as the hedged forecasted transactions occur. The following table rolls forward the components of AOCI, including reclassification adjustments, for the three months ended September 30, 2015.
