Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Jun. 30, 2014
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The interim unaudited consolidated financial statements of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted according to these SEC rules and regulations. Management believes that the disclosures included in these interim financial statements are adequate to make the information presented not misleading. The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. In the opinion of management, all normal and recurring adjustments necessary to present fairly the financial condition of the Company at June 30, 2014 and results of operations for all periods presented have been made. The results of operations for the six months ended June 30, 2014 should not be construed as indicative of the results to be expected for the full year. The accompanying consolidated financial statements of the Company have been prepared on the accrual basis of accounting in accordance with GAAP. 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. Although the Company’s estimates contemplate current conditions and how it expects them to change in the future, it is reasonably possible that actual conditions could be worse than anticipated in those estimates, which could materially impact the Company’s results of operations and its financial condition. Management has made significant estimates in several areas, including other-than-temporary impairment (“OTTI”) on Agency and Non-Agency MBS (Note 3), valuation of Agency and Non-Agency MBS (Notes 3 and 14), derivative instruments (Notes 5 and 14) and income recognition on certain Non-Agency MBS purchased at a discount (Note 3). In addition, estimates are used in the determination of taxable income used in the assessment of REIT compliance and contingent liabilities for related taxes, penalties and interest (Note 2(n)). Actual results could differ from those estimates. The consolidated financial statements of the Company include the accounts of all subsidiaries; significant intercompany accounts and transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation.
Agency and Non-Agency MBS (including Non-Agency MBS transferred to a consolidated VIE)	Agency and Non-Agency MBS (including Non-Agency MBS transferred to a consolidated VIE) The Company has investments in residential MBS that are issued or guaranteed as to principal and/or interest by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or any agency of the U.S. Government, such as Ginnie Mae (collectively, “Agency MBS”), and residential MBS that are not guaranteed by any U.S. Government agency or any federally chartered corporation (“Non-Agency MBS”), as described in Note 3. Designation The Company generally intends to hold its MBS until maturity; however, from time to time, it may sell any of its securities as part of the overall management of its business. As a result, all of the Company’s MBS are designated as “available-for-sale” and, accordingly, are carried at their fair value with unrealized gains and losses excluded from earnings (except when an OTTI is recognized, as discussed below) and reported in accumulated other comprehensive income/(loss) (“AOCI”), a component of stockholders’ equity. Upon the sale of an investment security, any unrealized gain or loss is reclassified out of AOCI to earnings as a realized gain or loss using the specific identification method. Revenue Recognition, Premium Amortization and Discount Accretion Interest income on securities is accrued based on the outstanding principal balance and their contractual terms. Premiums and discounts associated with Agency MBS and Non-Agency MBS assessed as high credit quality at the time of purchase are amortized into interest income over the life of such securities using the effective yield method. Adjustments to premium amortization are made for actual prepayment activity. Interest income on the Non-Agency MBS that were purchased at a discount to par value and/or are considered to be of less than high credit quality is recognized based on the security’s effective interest rate which is the security's internal rate of return (“IRR”). The IRR is determined using management’s estimate of the projected cash flows for each security, which are based on the Company’s observation of current information and events and include assumptions related to fluctuations in interest rates, prepayment speeds and the timing and amount of credit losses. On at least a quarterly basis, the Company reviews and, if appropriate, makes adjustments to its cash flow projections based on input and analysis received from external sources, internal models, and its judgment about interest rates, prepayment rates, the timing and amount of credit losses, and other factors. Changes in cash flows from those originally projected, or from those estimated at the last evaluation, may result in a prospective change in the IRR/interest income recognized on these securities or in the recognition of OTTIs. (See Note 3) Based on the projected cash flows from the Company’s Non-Agency MBS purchased at a discount to par value, a portion of the purchase discount may be designated as non-accretable purchase discount (“Credit Reserve”), which effectively mitigates the Company’s risk of loss on the mortgages collateralizing such MBS and is not expected to be accreted into interest income. The amount designated as Credit Reserve may be adjusted over time, based on the actual performance of the security, its underlying collateral, actual and projected cash flow from such collateral, economic conditions and other factors. If the performance of a security with a Credit Reserve is more favorable than forecasted, a portion of the amount designated as Credit Reserve may be reallocated to accretable discount and recognized into interest income over time. Conversely, if the performance of a security with a Credit Reserve is less favorable than forecasted, the amount designated as Credit Reserve may be increased, or impairment charges and write-downs of such securities to a new cost basis could result. Determination of MBS Fair Value In determining the fair value of the Company’s MBS, management considers a number of observable market data points, including prices obtained from pricing services, brokers and repurchase agreement counterparties, dialogue with market participants, as well as management’s observations of market activity. (See Note 14) Impairments/OTTI When the fair value of an investment security is less than its amortized cost at the balance sheet date, the security is considered impaired. The Company assesses its impaired securities on at least a quarterly basis and designates such impairments as either “temporary” or “other-than-temporary.” If the Company intends to sell an impaired security, or it is more likely than not that it will be required to sell the impaired security before its anticipated recovery, then the Company must recognize an OTTI through charges to earnings equal to the entire difference between the investment’s amortized cost and its fair value at the balance sheet date. If the Company does not expect to sell an other-than-temporarily impaired security, only the portion of the OTTI related to credit losses is recognized through charges to earnings with the remainder recognized through AOCI on the consolidated balance sheets. Impairments recognized through other comprehensive income/(loss) (“OCI”) do not impact earnings. Following the recognition of an OTTI through earnings, a new cost basis is established for the security and may not be adjusted for subsequent recoveries in fair value through earnings. However, OTTIs recognized through charges to earnings may be accreted back to the amortized cost basis of the security on a prospective basis through interest income. The determination as to whether an OTTI exists and, if so, the amount of credit impairment recognized in earnings is subjective, as such determinations are based on factual information available at the time of assessment as well as the Company’s estimates of the future performance and cash flow projections. As a result, the timing and amount of OTTIs constitute material estimates that are susceptible to significant change. (See Note 3) Non-Agency MBS that are assessed to be of less than high credit quality and on which impairments are recognized have experienced, or are expected to experience, credit-related adverse cash flow changes. The Company’s estimate of cash flows for its Non-Agency MBS is based on its review of the underlying mortgage loans securing the MBS. The Company considers information available about the past and expected future performance of underlying mortgage loans, including timing of expected future cash flows, prepayment rates, default rates, loss severities, delinquency rates, percentage of non-performing loans, Fair Isaac Corporation (“FICO”) scores at loan origination, year of origination, loan-to-value ratios (“LTVs”), geographic concentrations, as well as reports by credit rating agencies, such as Moody’s Investors Services, Inc. (“Moody’s”), Standard & Poor’s Corporation (“S&P”), or Fitch, Inc. (collectively, “Rating Agencies”), general market assessments, and dialogue with market participants. As a result, significant judgment is used in the Company’s analysis to determine the expected cash flows for its Non-Agency MBS. In determining the OTTI related to credit losses for securities that were purchased at significant discounts to par and/or are considered to be of less than high credit quality, the Company compares the present value of the remaining cash flows expected to be collected at the purchase date (or last date previously revised) against the present value of the cash flows expected to be collected at the current financial reporting date. The discount rate used to calculate the present value of expected future cash flows is the current yield used for income recognition purposes. Impairment assessment for Non-Agency MBS that were purchased at prices close to par and are considered to be of high credit quality involves comparing the present value of the remaining cash flows expected to be collected against the amortized cost of the security at the assessment date. The discount rate used to calculate the present value of the expected future cash flows is based on the instrument’s IRR. Balance Sheet Presentation The Company’s MBS pledged as collateral against repurchase agreements and Swaps are included in MBS on the consolidated balance sheets with the fair value of the MBS pledged disclosed parenthetically. Purchases and sales of securities are recorded on the trade date. However, if on the purchase settlement date, a repurchase agreement is used to finance the purchase of an MBS with the same counterparty and such transactions are determined to be linked, then the MBS and linked repurchase borrowing will be reported on the same settlement date as Linked Transactions. (See Notes 2(o) and 5)
Securities Obtained and Pledged as Collateral/Obligation to Return Securities Obtained as Collateral	Securities Obtained and Pledged as Collateral/Obligation to Return Securities Obtained as Collateral The Company has obtained securities as collateral under collateralized financing arrangements in connection with its financing strategy for Non-Agency MBS. Securities obtained as collateral in connection with these transactions are recorded on the Company’s consolidated balance sheets as an asset along with a liability representing the obligation to return the collateral obtained, at fair value. While beneficial ownership of securities obtained remains with the counterparty, the Company has the right to sell the collateral obtained or to pledge it as part of a subsequent collateralized financing transaction. (See Note 2(j) for Repurchase Agreements and Reverse Repurchase Agreements)
Residential Whole Loans	Residential Whole Loans Residential whole loans included in the Company’s consolidated balance sheets are comprised of pools of fixed and adjustable rate residential mortgage loans. The Company has acquired these loans through a consolidated trust at discounted purchase prices that reflect, in part, the credit quality of the borrowers. While the majority of such loans are currently performing in accordance with their current contractual terms, for accounting purposes the loans are considered by the Company to be credit impaired at purchase as the borrowers have previously experienced payment delinquencies and the amount owed on the mortgage loan may exceed the value of the property pledged as collateral. Consequently, the Company has assessed that these loans have a higher likelihood of default than newly originated mortgage loans. The Company believes that amounts paid to acquire residential whole loans represent fair market value at the date of acquisition. Residential whole loans are initially recorded at fair value with no allowance for loan losses. Subsequent to acquisition, the recorded amount reflects the original investment amount, plus accretion of interest income, less principal and interest cash flows received and principal amounts forgiven or otherwise charged off as they are considered not recoverable. Residential whole loans are presented in Prepaid and other assets in the Company's consolidated balance sheets at carrying value, which reflects the recorded amount net of any allowance for loan losses established subsequent to acquisition. The Company may aggregate into pools loans acquired in the same fiscal quarter that are assessed as having similar risk characteristics. For each pool established, or on an individual loans basis for loans not aggregated into pools, the Company estimates at acquisition and periodically on at least a quarterly basis, the principal and interest cash flows expected to be collected. The difference between the cash flows expected to be collected and the carrying amount of the loans is referred to as the “accretable yield”. This amount is accreted as interest income over the life of the loans using an effective interest rate (level yield) methodology. Interest income recorded each period reflects the amount of accretable yield recognized and not the coupon interest payments received on the underlying loans. The difference between contractually required principal and interest payments and the cash flows expected to be collected, referred to as the “nonaccretable difference,” includes estimates of both the impact of prepayments and expected credit losses over the life of the underlying loans. A decrease in expected cash flows in subsequent periods may indicate impairment at the pool and/or individual loan level thus requiring the establishment of an allowance for loan losses by a charge to the provision for loan losses. The allowance for loan losses represents the present value of cash flows expected at acquisition that are no longer expected to be received at the relevant measurement date. An increase in expected cash flows in subsequent periods initially reduces any previously established allowance for loan losses by the increase in the present value of cash flows expected to be collected, and results in a recalculation of the amount of accretable yield. The adjustment of accretable yield due to an increase in expected cash flows is accounted for prospectively as a change in estimate and results in reclassification from nonaccretable difference to accretable yield. (See Note 15)
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on deposit with financial institutions and investments in money market funds, all of which have original maturities of three months or less. Cash and cash equivalents may also include cash pledged as collateral to the Company by its repurchase agreement and/or Swap counterparties as a result of reverse margin calls (i.e., margin calls made by the Company). The Company did not hold any cash pledged by its counterparties at June 30, 2014 or December 31, 2013. At June 30, 2014 and December 31, 2013, all of the Company’s cash investments were comprised of overnight money market funds, which are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. (See Notes 7 and 14)
Restricted Cash	Restricted Cash Restricted cash represents the Company’s cash held by its counterparties as collateral against the Company’s Swaps and/or repurchase agreements. Restricted cash, which earns interest, is not available to the Company for general corporate purposes, but may be applied against amounts due to counterparties to the Company’s repurchase agreements and/or Swaps, or returned to the Company when the collateral requirements are exceeded or at the maturity of the Swap or repurchase agreement. The Company had aggregate restricted cash held as collateral against its Swaps and repurchase agreements of $54.4 million at June 30, 2014 and $37.5 million held as collateral against its Swaps at December 31, 2013. (See Notes 5, 6, 7 and 14)
Goodwill	Goodwill At June 30, 2014 and December 31, 2013, the Company had goodwill of $7.2 million, which represents the unamortized portion of the excess of the fair value of its common stock issued over the fair value of net assets acquired in connection with its formation in 1998. Goodwill is tested for impairment at least annually, or more frequently under certain circumstances, at the entity level. Through June 30, 2014, the Company had not recognized any impairment against its goodwill.
Depreciation	Depreciation Leasehold Improvements and Other Depreciable Assets Depreciation is computed on the straight-line method over the estimated useful life of the related assets or, in the case of leasehold improvements, over the shorter of the useful life or the lease term. Furniture, fixtures, computers and related hardware have estimated useful lives ranging from five to eight years at the time of purchase.
Resecuritization and Senior Notes Related Costs	Resecuritization and Senior Notes Related Costs Resecuritization related costs are costs associated with the issuance of beneficial interests by consolidated VIEs and incurred by the Company in connection with various resecuritization transactions completed by the Company. Senior Notes related costs are costs incurred by the Company in connection with the issuance of its Senior Notes in April, 2012. These costs may include underwriting, rating agency, legal, accounting and other fees. Such costs, which reflect deferred charges, are included on the Company’s consolidated balance sheets in Prepaid and other assets. These deferred charges are amortized as an adjustment to interest expense using the effective interest method, based upon the actual repayments of the associated beneficial interests issued to third parties and over the stated legal maturity of the Senior Notes. The Company periodically reviews the recoverability of these deferred costs and in the event an impairment charge is required, such amount shall be included within Operating and other expense on the Company’s consolidated statement of operations.
Repurchase Agreements and Reverse Repurchase Agreements	Repurchase Agreements and Reverse Repurchase Agreements The Company finances the acquisition of a significant portion of its MBS with repurchase agreements. Under 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 sale 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 legally structured as sale and repurchase transactions, the Company accounts for repurchase agreements as secured borrowings, with the exception of certain repurchase agreements accounted for as components of Linked Transactions. (See Note 2(o) below.) Under its repurchase agreements, the Company pledges its securities as collateral to secure the borrowing, which is equal in value to a specified percentage of the fair value of the pledged collateral, while the Company retains beneficial ownership of the pledged collateral. At the maturity of a repurchase financing, unless the repurchase financing is renewed with the same counterparty, the Company is required to repay the loan including any accrued interest and concurrently receives back its pledged collateral from the lender. With the consent of the lender, the Company may renew a repurchase financing at the then prevailing financing terms. Margin calls, whereby a lender requires that the Company pledge additional securities or cash as collateral to secure borrowings under its repurchase financing with such lender, are routinely experienced by the Company when the value of the MBS pledged as collateral declines as a result of principal amortization and prepayments or due to changes in market interest rates, spreads or other market conditions. The Company also may make margin calls on counterparties when collateral values increase. The Company’s repurchase financings typically have terms ranging from one month to six months at inception, but may also have longer or shorter terms. Should a counterparty decide not to renew a repurchase financing at maturity, the Company must either refinance elsewhere or be in a position to satisfy the obligation. If, during the term of a repurchase financing, a lender should default on its obligation, the Company might experience difficulty recovering its pledged assets which could result in an unsecured claim against the lender for the difference between the amount loaned to the Company plus interest due to the counterparty and the fair value of the collateral pledged by the Company to such lender, including accrued interest receivable or such collateral. (See Notes 2(o), 5, 6, 7 and 14) In addition to the repurchase agreement financing arrangements discussed above, as part of its financing strategy for Non-Agency MBS, the Company has entered into contemporaneous repurchase and reverse repurchase agreements with a single counterparty. Under a typical reverse repurchase agreement, the Company buys securities from a borrower for cash and agrees to sell the same securities in the future for a price that is higher than the original purchase price. The difference between the purchase price the Company originally paid and the sale price represents interest received from the borrower. In contrast, the contemporaneous repurchase and reverse repurchase transactions effectively resulted in the Company pledging Non-Agency MBS as collateral to the counterparty in connection with the repurchase agreement financing and obtaining U.S. Treasury securities as collateral from the same counterparty in connection with the reverse repurchase agreement. No net cash was exchanged between the Company and counterparty at the inception of the transactions. Securities obtained and pledged as collateral are recorded as an asset on the Company’s consolidated balance sheets. Interest income is recorded on the reverse repurchase agreement and interest expense is recorded on the repurchase agreement on an accrual basis. Both the Company and the counterparty have the right to make daily margin calls based on changes in the value of the collateral obtained and/or pledged. The Company’s liability to the counterparty in connection with this financing arrangement is recorded on the Company’s consolidated balance sheets and disclosed as “Obligation to return securities obtained as collateral.” (See Note 2(c))
Equity-Based Compensation	Equity-Based Compensation Compensation expense for equity based awards is recognized ratably over the vesting period of such awards, based upon the fair value of such awards at the grant date. With respect to awards granted in 2009 and prior years, the Company has applied a zero forfeiture rate for these awards, as they were granted to a limited number of employees, and historical forfeitures have been minimal. Forfeitures, or an indication that forfeitures are expected to occur, may result in a revised forfeiture rate and would be accounted for prospectively as a change in estimate. During 2010, the Company granted certain restricted stock units (“RSUs”) that vest after either two or four years of service and provided that certain criteria are met, which are based on a formula that includes changes in the Company’s closing stock price over a two- or four-year period and dividends declared on the Company’s common stock during those periods. From 2011 through 2013, the Company granted certain RSUs that vest annually over a one or three-year period, provided that certain criteria are met, which are based on a formula that includes changes in the Company’s closing stock price over the annual vesting period and dividends declared on the Company’s common stock during those periods. During 2014, the Company made grants of RSUs certain of which generally cliff vest after a three-year period and certain of which generally cliff vest after a three-year period subject to the achievement of a market-based condition that is based on a formula tied to the Company’s achievement of average total stockholder return during the three-year period. Such criteria constitute a “market condition” which impacts the amount of compensation expense recognized for these awards. Specifically, the uncertainty regarding whether the market condition will be achieved is reflected in the grant date fair valuation of the RSUs, which in addition to estimates regarding the amount of RSUs expected to be forfeited during the associated service period, determines the amount of compensation expense that is recognized. Compensation expense is not reversed should the market condition not be achieved, while differences in actual forfeiture experience relative to estimated forfeitures will result in adjustments to the timing and amount of compensation expense recognized. The Company has awarded DERs that may be attached to or awarded separately from other equity based awards. Compensation expense for separately awarded DERs is based on the grant date fair value of such awards and is recognized over the vesting period. Payments pursuant to these DERs are charged to stockholders’ equity. Payments pursuant to DERs that are attached to equity based awards are charged to stockholders’ equity to the extent that the attached equity awards are expected to vest. Compensation expense is recognized for payments made for DERs to the extent that the attached equity awards do not or are not expected to vest and grantees are not required to return payments of dividends or DERs to the Company. (See Notes 2(l) and 13)
Earnings per Common Share ("EPS")	Earnings per Common Share (“EPS”) Basic EPS is computed using the two-class method, which includes the weighted-average number of shares of common stock outstanding during the period and other securities that participate in dividends, such as the Company’s unvested restricted stock and RSUs that have non-forfeitable rights to dividends and DERs attached to/associated with RSUs and vested stock options to arrive at total common equivalent shares. In applying the two-class method, earnings are allocated to both shares of common stock and securities that participate in dividends based on their respective weighted-average shares outstanding for the period. For the diluted EPS calculation, common equivalent shares are further adjusted for the effect of dilutive unexercised stock options and RSUs outstanding that are unvested and have dividends that are subject to forfeiture using the treasury stock method. Under the treasury stock method, common equivalent shares are calculated assuming that all dilutive common stock equivalents are exercised and the proceeds, along with future compensation expenses associated with such instruments, are used to repurchase shares of the Company’s outstanding common stock at the average market price during the reported period. (See Note 12)
Comprehensive Income/(Loss)	Comprehensive Income/(Loss) The Company’s comprehensive income/(loss) available to common stock and participating securities includes net income, the change in net unrealized gains/(losses) on its MBS and Swaps, (to the extent that such changes are not recorded in earnings), adjusted by realized net gains/(losses) reclassified out of AOCI for MBS and is reduced by dividends declared on the Company’s preferred stock and issuance costs of redeemed preferred stock.
U.S. Federal Income Taxes	U.S. Federal Income Taxes The Company has elected to be taxed as a REIT under the provisions of the Internal Revenue Code of 1986, as amended, (the “Code”) and the corresponding provisions of state law. The Company expects to operate in a manner that will enable it to satisfy the various requirements to maintain its status as a REIT. In order to maintain its status a REIT, the Company must, among other things, distribute at least 90% of its REIT taxable income (excluding net long-term capital gains) to stockholders in the timeframe permitted by the Code. As long as the Company maintains its status as a REIT, the Company will not be subject to regular Federal income tax to the extent that it distributes 100% of its REIT taxable income (including net long-term capital gains) to its stockholders within the permitted timeframe. Should this not occur, the Company would be subject to federal taxes at prevailing corporate tax rates on the difference between its REIT taxable income and the amounts deemed to be distributed for that tax year. As the Company’s objective is to distribute 100% of its REIT taxable income to its stockholders within the permitted timeframe, no provision for current or deferred income taxes has been made in the accompanying consolidated financial statements. Should the Company incur a liability for corporate income tax, such amounts would be recorded as REIT income tax expense on the Company’s consolidated statements of operations. Furthermore, if the Company fails to distribute during each calendar year, or by the end of January following the calendar year in the case of distributions with declaration and record dates falling in the last three months of the calendar year, at least the sum of (i) 85% its REIT ordinary income for such year; (ii) 95% of its REIT capital gain income for such year and; (iii) any undistributed taxable income from prior periods, the Company will be subject to a 4% nondeductible excise tax on the excess of such required distribution over the amounts actually distributed. To the extent that the Company incurs interest, penalties or related excise taxes in connection with its tax obligations, including as a result of its assessment of uncertain tax positions, such amounts shall be included within Operating and other expense on the Company’s consolidated statements of operations. Based on its analysis of any potential uncertain tax positions, the Company concluded that it does not have any material uncertain tax positions that meet the relevant recognition or measurement criteria as of June 30, 2014, December 31, 2013, or June 30, 2013. The Company expects to file its 2013 tax return prior to September 15, 2014. The Company’s tax returns for tax years 2009 through 2012 are open to examination.
Derivative Financial Instruments	Derivative Financial Instruments The Company uses a variety of derivative instruments to economically hedge a portion of its exposure to market risks, including interest rate risk, prepayment risk and extension risk. The objective of the Company’s risk management strategy is to reduce fluctuations in net book value over a range of interest rate scenarios. In particular, the Company attempts to mitigate the risk of the cost of its variable rate liabilities increasing during a period of rising interest rates. The Company’s derivative instruments are primarily comprised of Swaps, the majority of which are designated as cash flow hedges against the interest rate risk associated with its borrowings. During 2013, the Company also entered into forward contracts for the sale of Agency MBS securities on a generic pool, or to-be-announced basis (“TBA short positions”) and Linked Transactions. TBA short positions and Linked Transactions are not designated as hedging instruments. Linked Transactions It is presumed that the initial transfer of a financial asset (i.e., the purchase of an MBS by the Company) and contemporaneous repurchase financing of such MBS with the same counterparty are considered part of the same arrangement, or a “linked transaction,” unless certain criteria are met. The two components of a linked transaction (MBS purchase and repurchase financing) are not reported separately but are evaluated on a combined basis and reported as a forward (derivative) contract and are presented as “Linked Transactions” on the Company’s consolidated balance sheets. Changes in the fair value of the assets and liabilities underlying Linked Transactions and associated interest income and expense are reported as “unrealized net gains/(losses) and net interest income from Linked Transactions” on the Company’s consolidated statements of operations and are not included in OCI. However, if certain criteria are met, the initial transfer (i.e., the purchase of a security by the Company) and repurchase financing will not be treated as a Linked Transaction and will be evaluated and reported separately, as an MBS purchase and repurchase financing. When or if a transaction is no longer considered to be linked, the MBS and repurchase financing will be reported on a gross basis. In this case, the fair value of the MBS at the time the transactions are no longer considered linked will become the cost basis of the MBS, and the income recognition yield for such MBS will be calculated prospectively using this new cost basis. (See Notes 5 and 14) Swaps The Company documents its risk-management policies, including objectives and strategies, as they relate to its hedging activities and the relationship between the hedging instrument and the hedged liability for all Swaps designated as hedging transactions. The Company assesses, both at inception of a hedge and on a quarterly basis thereafter, whether or not the hedge is “highly effective.” Swaps are carried on the Company’s balance sheets at fair value, as assets, if their fair value is positive, or as liabilities, if their fair value is negative. Changes in the fair value of the Company’s Swaps designated in hedging transactions are recorded in OCI provided that the hedge remains effective. Changes in fair value for any ineffective amount of a Swap are recognized in earnings. The Company has not recognized any change in the value of its existing Swaps designated as hedges through earnings as a result of hedge ineffectiveness. The Company discontinues hedge accounting on a prospective basis and recognizes changes in the fair value through earnings when: (i) it is determined that the derivative is no longer effective in offsetting cash flows of a hedged item (including forecasted transactions); (ii) it is no longer probable that the forecasted transaction will occur; or (iii) it is determined that designating the derivative as a hedge is no longer appropriate. Although permitted under certain circumstances, the Company does not offset cash collateral receivables or payables against its net derivative positions. (See Notes 5, 7 and 14) TBA Short Positions During 2013, the Company entered into TBA short positions as a means of managing interest rate risk and MBS basis risk associated with its investment and financing activities. A TBA short position is a forward contract for sale of Agency MBS at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific Agency MBS that could be delivered into the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association (“SIFMA”), are not known at the time of the transaction. The Company accounts for TBA short positions as derivative instruments since it cannot assert that it is probable at inception and throughout the term of the TBA contract that it will physically deliver the agency security upon settlement of the contract. The Company presents TBA short positions as either derivative assets or liabilities, at fair value on its consolidated balance sheets. Gains and losses associated with TBA short positions are reported in Other income on the Company’s consolidated statements of operations. The Company did not have any TBA short positions at June 30, 2014 and December 31, 2013.
Fair Value Measurements and the Fair Value Option for Financial Assets and Financial Liabilities	Fair Value Measurements and the Fair Value Option for Financial Assets and Financial Liabilities The Company’s presentation of fair value for its financial assets and liabilities is determined within a framework that stipulates that the fair value of a financial asset or liability is an exchange price in an orderly transaction between market participants to sell the asset or transfer the liability in the market in which the reporting entity would transact for the asset or liability, that is, the principal or most advantageous market for the asset or liability. The transaction to sell the asset or transfer the liability is a hypothetical transaction at the measurement date, considered from the perspective of a market participant that holds the asset or owes the liability. This definition of fair value focuses on exit price and prioritizes the use of market-based inputs over entity-specific inputs when determining fair value. In addition, the framework for measuring fair value establishes a three-level hierarchy for fair value measurements based upon the observability of inputs to the valuation of an asset or liability as of the measurement date. (See Note 14) Although permitted under GAAP to measure many financial instruments and certain other items at fair value, the Company has not elected the fair value option for any of its assets or liabilities. If the fair value option is elected, unrealized gains and losses on such items for which fair value is elected would be recognized in earnings at each subsequent reporting date. A decision to elect the fair value option for an eligible financial instrument, which may be made on an instrument by instrument basis, is irrevocable.
Variable Interest Entities and Other Consolidated Special Purpose Entities	Variable Interest Entities and Other Consolidated Special Purpose Entities An entity is referred to as a VIE if it meets at least one of the following criteria: (i) the entity has equity that is insufficient to permit the entity to finance its activities without additional subordinated financial support of other parties; or (ii) as a group, the holders of the equity investment at risk lack (a) the power to direct the activities of an entity that most significantly impact the entity’s economic performance; (b) the obligation to absorb the expected losses; or (c) the right to receive the expected residual returns; or (iii) have disproportional voting rights and the entity’s activities are conducted on behalf of the investor that has disproportionally few voting rights. The Company consolidates a VIE when it has both the power to direct the activities that most significantly impact the economic performance of the VIE and a right to receive benefits or absorb losses of the entity that could be potentially significant to the VIE. The Company is required to reconsider its evaluation of whether to consolidate a VIE each reporting period, based upon changes in the facts and circumstances pertaining to the VIE. The Company has entered into resecuritization transactions which result in the Company consolidating the VIEs that were created to facilitate the transactions and to which the underlying assets in connection with the resecuritizations were transferred. In determining the accounting treatment to be applied to these resecuritization transactions, the Company evaluated whether the entities used to facilitate these transactions were VIEs and, if so, whether they should be consolidated. Based on its evaluation, the Company concluded that the VIEs should be consolidated. If the Company had determined that consolidation was not required, it would have then assessed whether the transfer of the underlying assets would qualify as a sale or should be accounted for as secured financings under GAAP. Prior to the completion of its initial resecuritization transaction in October 2010, the Company had not transferred assets to VIEs or Qualifying Special Purpose Entities (“QSPEs”) and other than acquiring MBS issued by such entities, had no other involvement with VIEs or QSPEs. (See Note 15) The Company also includes in its consolidated balance sheets certain financial assets and liabilities that are acquired/issued by trusts and/or other special purpose entities that have been evaluated as being required to be consolidated by the Company under the applicable accounting guidance.
Offering Costs Related to Issuance and Redemption of Preferred Stock	Offering Costs Related to Issuance and Redemption of Preferred Stock Offering costs related to issuance of preferred stock are recorded as a reduction in Additional paid-in capital, a component of stockholders’ equity, at the time such preferred stock is issued. On redemption of preferred stock, any excess of the fair value of the consideration transferred to the holders of the preferred stock over the carrying amount of the preferred stock in the Company’s consolidated balance sheets is included in the determination of Net Income Available to Common Stock and Participating Securities in the calculation of EPS. (See Notes 11 and 12)
New Accounting Standards and Interpretations	New Accounting Standards and Interpretations Accounting Standards Adopted in 2014 Financial Services - Investment Companies In June 2013, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-08, Financial Services - Investment Companies: Amendments to the Scope, Measurement, and Disclosure Requirements (“ASU 2013-08”). In general, the amendments of this ASU: (i) revise the definition of an investment company; (ii) require an investment company to measure non-controlling ownership interests in other investment companies at fair value rather than using the equity method of accounting; and (iii) require information to be disclosed concerning the status of the entity and any financial support provided, or contractually required to be provided, by the investment company to its investees. The Company’s adoption of ASU 2013-08 beginning on January 1, 2014 did not have a material impact on the Company’s consolidated financial statements as the FASB has decided to retain the current U.S. GAAP scope exception from investment company accounting and financial reporting for real estate investment trusts.
