Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies (A) Basis of Presentation: The Company's unaudited interim consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America, or "U.S. GAAP," for investment companies, ASC 946, Financial Services—Investment Companies ("ASC 946"). The Company has determined that it meets the definition of an investment company under ASC 946 . ASC 946 requires, among other things, that investments be reported at fair value in the financial statements. Additionally under ASC 946 the Company generally will not consolidate its interest in any company other than in its subsidiaries that qualify as investment companies under ASC 946. The consolidated financial statements include the accounts of the Company, the Operating Partnership, and its subsidiaries. All intercompany balances and transactions have been eliminated. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In management's opinion, all material adjustments, considered necessary for a fair presentation of the Company's interim consolidated financial statements have been included and are only of a normal recurring nature. Interim results are not necessarily indicative of the results that may be expected for the entire fiscal year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2015. (B) Valuation: The Company applies ASC 820-10, Fair Value Measurement and Disclosures ("ASC 820-10"), to its holdings of financial instruments. ASC 820-10 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: • Level 1—inputs to the valuation methodology are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Currently, the types of financial instruments the Company generally includes in this category are listed equities, exchange-traded derivatives, and cash equivalents; • Level 2—inputs to the valuation methodology other than quoted prices included in Level 1 are observable for the asset or liability, either directly or indirectly. Currently, the types of financial instruments that the Company generally includes in this category are Agency RMBS, non-Agency mortgage-backed securities determined to have sufficiently observable market data, U.S. Treasury securities and certain sovereign debt, commonly traded derivatives, such as interest rate swaps and foreign currency forwards, and certain other over-the-counter derivatives; and • Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement. The types of financial instruments that the Company generally includes in this category are RMBS, CMBS, ABS, credit default swaps, or "CDS," on individual ABS, distressed corporate debt, and total return swaps on distressed corporate debt, in each case where there is less price transparency. Also included in this category are residential and commercial mortgage loans, consumer loans, non-listed equities, and private corporate debt and equity investments. For certain financial instruments, the various inputs that management uses to measure fair value for such financial instrument may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for such financial instrument is based on the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the various inputs that management uses to measure fair value with the highest priority to inputs that are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets (Level 1) and the lowest priority to inputs that are unobservable and significant to the fair value measurement (Level 3). The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. The Company may use valuation techniques consistent with the market and income approaches to measure the fair value of its assets and liabilities. The market approach uses third-party valuations and information obtained from market transactions involving identical or similar assets or liabilities. The income approach uses projections of the future economic benefit of an instrument to determine its fair value, such as in the discounted cash flow methodology. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risk associated with investing in these financial instruments. Transfers between levels of the fair value hierarchy are assumed to occur at the end of the reporting period. Summary Valuation Techniques For financial instruments that are traded in an "active market," the best measure of fair value is the quoted market price. However, many of the Company's financial instruments are not traded in an active market. Therefore, management generally uses third-party valuations when available. If third-party valuations are not available, management uses other valuation techniques, such as the discounted cash flow methodology. The following are summary descriptions, for various categories of financial instruments, of the valuation methodologies management uses in determining fair value of the Company's financial instruments in such categories. Management utilizes such methodologies to assign a good faith fair value (the estimated price that, in an orderly transaction at the valuation date, would be received to sell an asset, or paid to transfer a liability, as the case may be) to each such financial instrument. For mortgage-backed securities, or "MBS," including To Be Announced MBS, or "TBAs," CLOs, and distressed and non-distressed corporate debt and equity, management seeks to obtain at least one third-party valuation, and often obtains multiple valuations when available. Management has been able to obtain third-party valuations on the vast majority of these instruments and expects to continue to solicit third-party valuations in the future. Management generally values each financial instrument at the average of third-party valuations received and not rejected as described below. Third-party valuations are not binding, and while management generally does not adjust the valuations it receives, management may challenge or reject a valuation when, based on its validation criteria, management determines that such valuation is unreasonable or erroneous. Furthermore, based on its validation criteria, management may determine that the average of the third-party valuations received for a given instrument does not result in what management believes to be the fair value of such instrument, and in such circumstances management may override this average with its own good faith valuation. The validation criteria may take into account output from management's own models, recent trading activity in the same or similar instruments, and valuations received from third parties. The use of proprietary models requires the use of a significant amount of judgment and the application of various assumptions including, but not limited to, assumptions concerning future prepayment rates and default rates. Valuations for fixed rate MBS pass-throughs issued by a U.S. government agency or government-sponsored enterprise are typically based on observable pay-up data (pay-ups are price premiums for specified categories of fixed rate pools relative to their TBA counterparts) or models that use observable market data, such as interest rates and historical prepayment speeds, and are validated against third-party valuations. Given their relatively high level of price transparency, Agency RMBS pass-throughs are typically designated as Level 2 assets, although Agency interest only and inverse interest only RMBS are currently designated as Level 3 assets since they generally have less price transparency. Non-Agency MBS and CLOs are generally classified as either Level 2 or Level 3 based on analysis of available market data such as recent trades and executable bids. The Company's investments in distressed corporate debt are in the form of loans as well as total return swaps on loans. Valuations are typically based on prices of the underlying loans received from widely used third-party pricing services. These investments as well as related non-listed equity investments are generally designated as Level 3 assets. Furthermore, the methodology used by the third-party valuation providers is reviewed at least annually by management, so as to ascertain whether such providers are utilizing observable market data to determine the valuations that they provide. For residential and commercial mortgage loans, consumer loans, and real estate owned properties, or "REO," management determines fair value by taking into account both external pricing data, when available, and internal pricing models. Non-performing mortgage loans and REO are typically valued based on management's estimates of the value of the underlying real estate, using various information including general economic data, broker price opinions, or "BPOs," recent sales, property appraisals, and bids. Performing mortgage loans and consumer loans are typically valued using discounted cash flows based on market assumptions and non-QM residential mortgage loans are valued using matrix pricing. Cash flow assumptions typically include projected default and prepayment rates and loss severities, and may include adjustments based on appraisals and BPOs. Mortgage and consumer loans and REO properties are classified as Level 3 assets. For financial derivatives with greater price transparency, such as CDS on asset-backed indices, CDS on corporate indices, certain options on the foregoing, and total return swaps on publicly-traded equities, market-standard pricing sources are used to obtain valuations; these financial derivatives are generally designated as Level 2 instruments. Interest rate swaps, swaptions, and foreign currency forwards are typically valued based on internal models that use observable market data, including applicable interest rates and foreign currency rates in effect as of the measurement date; the model-generated valuations are then typically compared to counterparty valuations for reasonableness. These financial derivatives are also generally designated as Level 2 instruments. Financial derivatives with less price transparency, such as CDS on individual ABS, are generally valued based on internal models, and are typically designated as Level 3 instruments. In the case of CDS on individual ABS, the valuation process typically starts with an estimation of the value of the underlying ABS. In valuing its derivatives, the Company also considers the creditworthiness of both the Company and its counterparties, along with collateral provisions contained in each derivative agreement. Investments in private operating entities, such as mortgage originators, are valued based on available metrics, such as relevant market multiples and comparable company valuations, and company specific-financial data including actual and projected results. These investments are designated as Level 3 assets. The Company's repurchase agreements are carried at fair value based on their contractual amounts as the debt is short-term in nature. The Company's reverse repurchase agreements are carried at cost, which approximates fair value. Repurchase and reverse repurchase agreements are classified as Level 2 assets and liabilities based on the adequacy of the collateral and their short term nature. The Company's valuation process, including the application of validation criteria, is overseen by the Manager's Valuation Committee ("Valuation Committee"). The Valuation Committee includes senior level executives from various departments within the Manager, and each quarter, the Valuation Committee reviews and approves the valuations of the Company's investments. The valuation process also includes a monthly review by the Company's third-party administrator. The goal of this review is to replicate various aspects of the Company's valuation process based on the Company's documented procedures. Because of the inherent uncertainty of valuation, the estimated fair value of the Company's financial instruments may differ significantly from the values that would have been used had a ready market for the financial instruments existed, and the differences could be material to the Company's consolidated financial statements. (C) Purchase and Sales of Investments and Investment Income: Purchases and sales of investments are generally recorded on trade date, and realized and unrealized gains and losses are calculated based on identified cost. The Company amortizes premiums and accretes discounts on its debt investments. Coupon interest income on fixed income investments is generally accrued based on the outstanding principal balance or notional amount and the current coupon interest rate. For Agency RMBS and debt securities that are deemed to be of high credit quality at the time of purchase, premiums and discounts are amortized into interest income over the life of such securities using the effective interest method. For securities whose cash flows vary depending on prepayments, an effective yield retroactive to the time of purchase is periodically recomputed based on actual prepayments and changes in projected prepayment activity, and a catch-up adjustment is made to amortization to reflect the cumulative impact of the change in effective yield. For debt securities (including non-Agency MBS) that are deemed not to be of high credit quality at the time of purchase, interest income is recognized based on the effective interest method. For purposes of determining the effective interest rate, management estimates the future expected cash flows of its investment holdings based on assumptions including, but not limited to, assumptions for future prepayment rates, default rates, and loss severities (each of which may in turn incorporate various macro-economic assumptions, such as future housing prices). These assumptions are re-evaluated not less than quarterly. Principal write-offs are generally treated as realized losses. Changes in projected cash flows, as applied to the current amortized cost of the security, may result in a prospective change in the yield/interest income recognized on such securities. For each loan purchased with the expectation that both interest and principal will be paid in full, the Company generally amortizes or accretes any premium or discount over the life of the loan utilizing the effective interest method. However, on at least a quarterly basis based on current information and events, the Company re-assesses the collectability of interest and principal, and designates a loan as impaired either when any payments have become 90 or more days past due, or when, in the opinion of management, it is probable that the Company will be unable to collect either interest or principal in full. Once a loan is designated as impaired, as long as principal is still expected to be collectable in full, interest payments are recorded as interest income only when received (i.e., under the cash basis method); accruals of interest income are only resumed when the loan becomes contractually current and performance is demonstrated to be resumed. However, if principal is not expected to be collectable in full, the cost recovery method is used (i.e., no interest income is recognized, and all payments received—whether contractually interest or principal—are applied to cost). For each loan purchased with evidence of credit deterioration since origination and the expectation that either principal or interest will not be paid in full, interest income is generally recognized using the effective interest method for as long as the cash flows can be reasonably estimated. Here, instead of amortizing the purchase discount (i.e., the excess of the unpaid principal balance over the purchase price) over the life of the loan, the Company effectively amortizes the accretable yield (i.e., the excess of the Company's estimate of the total cash flows to be collected over the life of the loan over the purchase price). Not less than quarterly, the Company updates its estimate of the cash flows expected to be collected over the life of the loan, and revised yields are prospectively applied. To the extent that cash flows cannot be reasonably estimated, these loans are generally accounted for under the cost recovery method. For certain groups of consumer loans that the Company considers as having sufficiently homogeneous characteristics, the Company aggregates such loans into pools, and accounts for each such pool as a single asset. The pool is then treated analogously to a debt security deemed not to be of high credit quality, in that (i) the aggregate premium or discount for the pool is amortized or accreted into interest income based on the pool's effective interest rate; (ii) the effective interest rate is determined based on the net expected cash flows of the pool, taking into account estimates of prepayments, defaults, and loss severities; and (iii) estimates are updated not less than quarterly and revised yields are prospectively applied. In estimating future cash flows on the Company's debt investments, there are a number of assumptions that will be subject to significant uncertainties and contingencies, including, in the case of MBS, assumptions relating to prepayment rates, default rates, loan loss severities, and loan repurchases. These estimates require the use of a significant amount of judgment. The Company receives dividend income on certain of its equity investments and rental income on certain of its REO properties. These items of income are included on the Consolidated Statement of Operations under the heading, "Other income." (D) Cash and Cash Equivalents: Cash and cash equivalents include cash and short term investments with original maturities of three months or less at the date of acquisition. Cash and cash equivalents typically include amounts held in an interest bearing overnight account and amounts held in money market funds, and these balances generally exceed insured limits. The Company holds its cash at institutions that it believes to be highly creditworthy. Restricted cash represents cash that the Company can use only for specific purposes. See Note 13 for further discussion of restricted cash balances. (E) Financial Derivatives: The Company enters into various types of financial derivatives. The Company's financial derivatives are predominantly subject to bilateral collateral arrangements or clearing in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. The Company may be required to deliver or receive cash or securities as collateral upon entering into derivative transactions. In addition, changes in the relative value of derivative transactions may require the Company or the counterparty to post or receive additional collateral. In the case of cleared derivatives, the clearinghouse becomes the Company's counterparty and a futures commission merchant acts as an intermediary between the Company and the clearinghouse with respect to all facets of the related transaction, including the posting and receipt of required collateral. Cash collateral received by the Company is reflected on the Consolidated Statement of Assets, Liabilities, and Equity as "Due to Brokers." Conversely, cash collateral posted by the Company is reflected as "Due from Brokers" on the Consolidated Statement of Assets, Liabilities, and Equity. The major types of derivatives utilized by the Company are swaps, futures, options, and forwards. Swaps: The Company may enter into various types of swaps, including interest rate swaps, credit default swaps, and total return swaps. The primary risk associated with the Company's interest rate swap activity is interest rate risk. The primary risk associated with the Company's credit default swaps is credit risk and the primary risks associated with the Company's total return swap activity are equity market risk and credit risk. The Company is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Primarily to help mitigate interest rate risk, the Company enters into interest rate swaps. Interest rate swaps are contractual agreements whereby one party pays a floating interest rate on a notional principal amount and receives a fixed rate payment on the same notional principal, or vice versa, for a fixed period of time. Interest rate swaps change in value with movements in interest rates. The Company enters into credit default swaps. A credit default swap is a contract under which one party agrees to compensate another party for the financial loss associated with the occurrence of a "credit event" in relation to a "reference amount" or notional value of a credit obligation (usually a bond, loan, or a basket of bonds or loans). The definition of a credit event may vary from contract to contract. A credit event may occur (i) when the underlying reference asset(s) fails to make scheduled principal or interest payments to its holders, (ii) with respect to credit default swaps referencing mortgage/asset-backed securities and indices, when the underlying reference obligation is downgraded below a certain rating level, or (iii) with respect to credit default swaps referencing corporate entities and indices, upon the bankruptcy of the underlying reference obligor. The Company typically writes (sells) protection to take a "long" position or purchases (buys) protection to take a "short" position with respect to underlying reference assets or to hedge exposure to other investment holdings. The Company enters into total return swaps in order to take a "long" or "short" position with respect to an underlying reference asset. The Company is subject to market price volatility of the underlying reference asset. A total return swap involves commitments to pay interest in exchange for a market-linked return based on a notional value. To the extent that the total return of the corporate debt, security, group of securities or index underlying the transaction exceeds or falls short of the offsetting interest obligation, the Company will receive a payment from or make a payment to the counterparty. Swaps change in value with movements in interest rates, credit quality, or total return of the reference securities. During the term of swap contracts, changes in value are recognized as unrealized gains or losses. When a contract is terminated, the Company realizes a gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Company's basis in the contract, if any. Periodic payments or receipts required by swap agreements are recorded as unrealized gains or losses when accrued and realized gains or losses when received or paid. Upfront payments paid and/or received by the Company to open swap contracts are recorded as an asset and/or liability on the Consolidated Statement of Assets, Liabilities, and Equity and are recorded as a realized gain or loss on the termination date. Futures Contracts: A futures contract is an exchange-traded agreement to buy or sell an asset for a set price on a future date. The Company enters into Eurodollar and/or U.S. Treasury security futures contracts to hedge its interest rate risk. The Company may also enter into various other futures contracts, including equity index futures. Initial margin deposits are made upon entering into futures contracts and can generally be either in the form of cash or securities. During the period the futures contract is open, changes in the value of the contract are recognized as unrealized gains or losses by marking-to-market to reflect the current market value of the contract. Variation margin payments are made or received periodically, depending upon whether unrealized losses or gains are incurred. When the contract is closed, the Company records a realized gain or loss equal to the difference between the proceeds of the closing transaction and the Company's basis in the contract. Options: The Company may purchase or write put or call options contracts or enter into swaptions. The Company enters into options contracts typically to help mitigate overall market, credit, or interest rate risk depending on the type of options contract. However, the Company also enters into options contracts from time to time for speculative purposes. When the Company purchases an options contract, the option asset is initially recorded at an amount equal to the premium paid, if any, and is subsequently marked-to-market. Premiums paid for purchasing options contracts that expire unexercised are recognized on the expiration date as realized losses. If an options contract is exercised, the premium paid is subtracted from the proceeds of the sale or added to the cost of the purchase to determine whether the Company has realized a gain or loss on the related transaction. When the Company writes an options contract, the option liability is initially recorded at an amount equal to the premium received, if any, and is subsequently marked-to-market. Premiums received for writing options contracts that expire unexercised are recognized on the expiration date as realized gains. If an options contract is exercised, the premium received is subtracted from the cost of the purchase or added to the proceeds of the sale to determine whether the Company has realized a gain or loss on the related investment transaction. When the Company enters into a closing transaction, the Company will realize a gain or loss depending upon whether the amount from the closing transaction is greater or less than the premiums paid or received. The Company may also enter into options contracts that contain forward-settling premiums. In this case, no money is exchanged upfront. Instead the agreed-upon premium is paid by the buyer upon expiration of the option, regardless of whether or not the option is exercised. Forward Currency Contracts: A forward currency contract is an agreement between two parties to purchase or sell a specific quantity of currency with the delivery and settlement at a specific future date and exchange rate. During the period the forward currency contract is open, changes in the value of the contract are recognized as unrealized gains or losses. When the contract is settled, the Company records a realized gain or loss equal to the difference between the proceeds of the closing transaction and the Company's basis in the contract. Commitments to Purchase Residential Mortgage Loans: The Company enters into forward purchase commitments under flow agreements, whereby the Company commits to purchasing the loans based on pre-defined underwriting guidelines and at stated interest rates. Actual loan purchases are contingent upon successful loan closings. These commitments to purchase mortgage loans are classified as derivatives on the Company's Consolidated Statement of Assets, Liabilities, and Equity and are, therefore, recorded as assets or liabilities measured at fair value. Until the purchase commitment expires or the underlying loan closes, changes in the estimated fair value of such commitments are recognized as unrealized gains or losses in the Consolidated Statement of Operations. Financial derivatives disclosed on the Consolidated Condensed Schedule of Investments include: credit default swaps on asset-backed securities, credit default swaps on asset-backed indices, credit default swaps on corporate bond indices, credit default swaps on corporate bonds, interest rate swaps, total return swaps, futures contracts, foreign currency forwards, options contracts, warrants, and mortgage loan purchase commitments. Financial derivative assets are included in Financial derivatives—assets, at fair value on the Consolidated Statement of Assets, Liabilities, and Equity. Financial derivative liabilities are included in Financial derivatives—liabilities, at fair value on the Consolidated Statement of Assets, Liabilities, and Equity. In addition, financial derivative contracts are summarized by type on the Consolidated Condensed Schedule of Investments. (F) Investments Sold Short: When the Company sells securities short, it typically satisfies its security delivery settlement obligation by obtaining the security sold short from the same or a different counterparty. The Company generally is required to deliver cash or securities as collateral to the counterparty for the Company's obligation to return the borrowed security. The amount by which the market value of the obligation falls short of or exceeds the proceeds from the short sale is treated as an unrealized gain or loss, respectively. A realized gain or loss will be recognized upon the termination of a short sale if the market price is less or greater than the proceeds originally received. (G) Reverse Repurchase Agreements: The Company enters into reverse repurchase agreements with third-party broker-dealers whereby it sells securities under agreements to be repurchased at an agreed-upon price and date. The Company accounts for reverse repurchase agreements as collateralized borrowings, with the initial sale price representing the amount borrowed, and with the future repurchase price consisting of the amount borrowed plus interest, at the implied interest rate of the reverse repurchase agreement, on the amount borrowed over the term of the reverse repurchase agreement. The interest rate on a reverse repurchase agreement is based on competitive rates (or competitive market spreads, in the case of agreements with floating interest rates) at the time such agreement is entered into. When the Company enters into a reverse repurchase agreement, the lender establishes and maintains an account containing cash and/or securities having a value not less than the repurchase price, including accrued interest, of the reverse repurchase agreement. Reverse repurchase agreements are carried at their contractual amounts, which approximate fair value as the debt is short-term in nature. (H) Repurchase Agreements: The Company enters into repurchase agreement transactions with third-party broker-dealers whereby it purchases securities under agreements to resell at an agreed-upon price and date. In general, securities received pursuant to repurchase agreements are delivered to counterparties of short sale transactions. The interest rate on a repurchase agreement is based on competitive rates (or competitive market spreads, in the case of agreements with floating interest rates) at the time such agreement is entered into. Assets held pursuant to repurchase agreements are reflected as assets on the Consolidated Statement of Assets, Liabilities, and Equity. Repurchase agreements are carried at fair value based on their contractual amounts as the debt is short-term in nature. Repurchase and reverse repurchase agreements that are conducted with the same counterparty may be reported on a net basis if they meet the requirements of ASC 210-20, Balance Sheet Offsetting . (I) Securitized Debt: The Company entered into a securitization transaction in March 2016 to finance certain of its commercial mortgage loans and REO which was accounted for as a collateralized borrowing. The assets contributed to the securitization were not derecognized but rather, the liability issued by the securitization was recorded to reflect the financing of the securitized assets. Debt issuance costs associated with the securitized debt are amortized over the life of the securitized debt and included in interest expense. (J) When-Issued/Delayed Delivery Securities: The Company may purchase or sell securities on a when-issued or delayed delivery basis. Securities purchased or sold on a when-issued basis are traded for delivery beyond the normal settlement date at a s

(2) Shown in basis points. (3) Represent an estimation of where market participants might value an enterprise. (4) Represents transactions with a remaining term of less than one year. Third-party non-binding valuations are validated by comparing such valuations to internally generated prices based on the Company's models and to recent trading activity in the same or similar instruments. For those instruments valued using discounted and net discounted cash flows, collateral prepayments, losses, recoveries, and scheduled amortization are projected over the remaining life of the collateral and expressed as a percentage of the collateral's current principal balance. Averages are weighted based on the fair value of the related instrument. In the case of credit default swaps on asset-backed securities, averages are weighted based on each instrument's bond equivalent value. Bond equivalent value represents the investment amount of a corresponding position in the reference obligation, calculated as the difference between the outstanding principal balance of the underlying reference obligation and the fair value, inclusive of accrued interest, of the derivative contract. For those assets valued using the LIBOR Option Adjusted Spread ("OAS") valuation methodology, cash flows are projected using the Company's models over multiple interest rate scenarios, and these projected cash flows are then discounted using the LIBOR rates implied by each interest rate scenario. The LIBOR OAS of an asset is then computed as the unique constant yield spread that, when added to all LIBOR rates in each interest rate scenario generated by the model, will equate (a) the expected present value of the projected asset cash flows over all model scenarios to (b) the actual current market price of the asset. LIBOR OAS is therefore model-dependent. Generally speaking, LIBOR OAS measures the additional yield spread over LIBOR that an asset provides at its current market price after taking into account any interest rate options embedded in the asset. The Company considers the expected timeline to resolution in the determination of fair value for its non-performing commercial and residential loans. Material changes in any of the inputs above in isolation could result in a significant change to reported fair value measurements. Additionally, fair value measurements are impacted by the interrelationships of these inputs. For example, for instruments subject to prepayments and credit losses, such as non-Agency RMBS and consumer loans and ABS backed by consumer loans, a higher expectation of collateral prepayments will generally be accompanied by a lower expectation of collateral losses. Conversely, higher losses will generally be accompanied by lower prepayments. Because the Company's credit default swaps on asset-backed security holdings represent credit default swap contracts whereby the Company has purchased credit protection, such credit default swaps on asset-backed securities generally have the directionally opposite sensitivity to prepayments, losses, and recoveries as compared to the Company's long securities holdings. Prepayments do not represent a significant input for the Company's commercial mortgage-backed securities and commercial mortgage loans. Losses and recoveries do not represent a significant input for the Company's Agency RMBS interest only securities, given the guarantee of the issuing government agency or government-sponsored enterprise.

The table above incorporates changes in net unrealized gain (loss) for both Level 3 financial instruments held by the Company at June 30, 2016 , as well as Level 3 financial instruments disposed of by the Company during the three month period ended June 30, 2016 . For Level 3 financial instruments held by the Company at June 30, 2016 , change in net unrealized gain (loss) of $(2.2) million , $(0.03) million , $0.3 million , $(0.6) million , and $0.3 million , for the three month period ended June 30, 2016 relate to investments, investments sold short, financial derivatives–assets, financial derivatives–liabilities, and guarantees, respectively. As of June 30, 2016 , the Company transferred $8.8 million of non-Agency RMBS from Level 3 to Level 2. These assets were transferred from Level 3 to Level 2 based on an increased volume of observed trading of these and similar assets. This increase in observed trading activity has led to greater price transparency for these assets, thereby making a Level 2 designation appropriate in the Company's view. However, changes in the volume of observable inputs for these assets, such as a decrease in the volume of observed trading, could impact price transparency, and thereby cause a change in the level designation for these assets in future periods. In addition, as of June 30, 2016 , the Company transferred $12.8 million of non-Agency RMBS from Level 2 to Level 3. Since March 31, 2016, these securities have exhibited indications of a reduced level of price transparency.

The table above incorporates changes in net unrealized gain (loss) for both Level 3 financial instruments held by the Company at June 30, 2015 , as well as Level 3 financial instruments disposed of by the Company during the three month period ended June 30, 2015 . For Level 3 financial instruments held by the Company at June 30, 2015 , change in net unrealized gain (loss) of $(0.6) million , $1.2 million , $(1.7) million , and $1 thousand , for the three month period ended June 30, 2015 relate to investments, financial derivatives–assets, financial derivatives–liabilities, and securitized debt, respectively. As of June 30, 2015 , the Company transferred $21.0 million of non-Agency RMBS from Level 3 to Level 2. These assets were transferred from Level 3 to Level 2 based on an increased volume of observed trading of these and similar assets. This increase in observed trading activity has led to greater price transparency for these assets, thereby making a Level 2 designation appropriate in the Company's view. However, changes in the volume of observable inputs for these assets, such as a decrease in the volume of observed trading, could impact price transparency, and thereby cause a change in the level designation for these assets in future periods. In addition, as of June 30, 2015 , the Company transferred $20.2 million of non-Agency RMBS from Level 2 to Level 3. These securities have exhibited indications of a reduced level of price transparency. Examples of such indications include wider spreads relative to similar securities and a reduction in observable transactions involving these and similar securities. Changes in these indications could impact price transparency, and thereby cause a change in the level designation in future periods.

To Be Announced RMBS [Abstract]
To Be Announced RMBS	To Be Announced RMBS In addition to investing in pools of Agency RMBS, the Company transacts in the forward settling TBA market. Pursuant to these TBA transactions, the Company agrees to purchase or sell, for future delivery, Agency RMBS with certain principal and interest terms and certain types of underlying collateral, but the particular Agency RMBS to be delivered is not identified until shortly before the TBA settlement date. TBAs are liquid and have quoted market prices and represent the most actively traded class of MBS. The Company accounts for its TBAs as purchase and sales and uses TBAs primarily for hedging purposes, typically in the form of short positions. However, the Company may also invest in TBAs for speculative purposes, including holding long positions. Overall, the Company typically holds a net short position. The Company does not generally take delivery of TBAs; rather, it settles the associated receivable and payable with its trading counterparties on a net basis. Transactions with the same counterparty for the same TBA that result in a reduction of the position are treated as extinguished. The fair value of the Company's positions in long TBA contracts are reflected on the Consolidated Condensed Schedule of Investments under TBA–Fixed Rate Agency Securities and the fair value of the Company's positions in TBA contracts sold short are reflected on the Consolidated Condensed Schedule of Investments under TBA–Fixed Rate Agency Securities Sold Short. The payables and receivables related to the Company's TBA securities are included on the Consolidated Statement of Assets, Liabilities, and Equity in Payable for securities purchased and Receivable for securities sold, respectively. The below table details TBA assets, liabilities, and the respective related payables and receivables as of June 30, 2016 and December 31, 2015: As of June 30, 2016 December 31, 2015 Assets: (In thousands) TBA securities, at fair value (Current principal: $153,018 and $94,602, respectively) $ 161,619 $ 98,009 Receivable for securities sold relating to unsettled TBA sales 486,668 613,023 Liabilities: TBA securities sold short, at fair value (Current principal: -$455,613 and -$580,992, respectively) $ (488,151 ) $ (612,777 ) Payable for securities purchased relating to unsettled TBA purchases (161,563 ) (98,049 ) Net short TBA securities, at fair value (326,532 ) (514,768 )

As of June 30, 2016 and December 31, 2015, all of the Company's open written credit derivatives were credit default swaps on either mortgage/asset-backed indices (ABX and CMBX indices) or corporate bond indices (CDX), collectively referred to as credit indices, or on individual corporate bonds, for which the Company receives periodic payments at fixed rates from credit protection buyers, and is obligated to make payments to the credit protection buyer upon the occurrence of a "credit event" with respect to underlying reference assets. Written credit derivatives held by the Company at June 30, 2016 and December 31, 2015, are summarized below: Credit Derivatives Amount at June 30, 2016 Amount at (In thousands) Fair Value of Written Credit Derivatives, Net $ 93,307 $ 135,443 Fair Value of Purchased Credit Derivatives Offsetting Written Credit Derivatives with Third Parties (1) $ (902 ) $ (369 ) Notional Amount of Written Credit Derivatives (2) $ (741,569 ) $ (799,750 ) Notional Amount of Purchased Credit Derivatives Offsetting Written Credit Derivatives with Third Parties (1) $ 16,132 $ 17,322 (1) Offsetting transactions with third parties include purchased credit derivatives which have the same reference obligation. (2) The notional value is the maximum amount that a seller of credit protection would be obligated to pay, and a buyer of credit protection would receive upon occurrence of a "credit event." Movements in the value of credit default swap transactions may require the Company or the counterparty to post or receive collateral. Amounts due or owed under credit derivative contracts with an International Swaps and Derivatives Association, or "ISDA," counterparty may be offset against amounts due or owed on other credit derivative contracts with the same ISDA counterparty. As a result, the notional amount of written credit derivatives involving a particular underlying reference asset or index has been reduced (but not below zero) by the notional amount of any contracts where the Company has purchased credit protection on the same reference asset or index with the same ISDA counterparty. A credit default swap on a credit index or a corporate bond typically terminates at the stated maturity date in the case of corporate indices or bonds, or, in the case of ABX and CMBX indices, the date that all of the reference assets underlying the index are paid off in full, retired, or otherwise cease to exist. Implied credit spreads may be used to determine the market value of such contracts and are reflective of the cost of buying/selling credit protection. Higher spreads would indicate a greater likelihood that a seller will be obligated to perform ( i.e. , make payment) under the contract. In situations where the credit quality of the underlying reference assets has deteriorated, the percentage of notional values paid up front ("points up front") is frequently used as an indication of credit risk. Credit protection sellers entering the market would expect to be paid points up front corresponding to the approximate fair value of the contract. For the Company's written credit derivatives that were outstanding at June 30, 2016, implied credit spreads on such contracts ranged between 24.0 and 3,583.1 basis points. For the Company's written credit derivatives that were outstanding at December 31, 2015, implied credit spreads on such contracts ranged between 19.5 and 4,628.7 basis points. Total net up-front payments received relating to written credit derivatives outstanding at June 30, 2016 and December 31, 2015 were $97.9 million and $137.8 million , respectively.

Borrowings under Reverse Repurc

Debt Disclosure [Abstract]
Borrowings under Reverse Repurchase Agreements and Securitized Debt	Borrowings under Reverse Repurchase Agreements and Securitized Debt Reverse Repurchase Agreements The Company enters into reverse repurchase agreements. A reverse repurchase agreement involves the sale of an asset to a counterparty together with a simultaneous agreement to repurchase the transferred asset or similar asset from such counterparty at a future date. The Company accounts for its reverse repurchase agreements as collateralized borrowings, with the transferred assets effectively serving as collateral for the related borrowing. The Company's reverse repurchase agreements typically range in term from 30 to 180 days, although the Company also has reverse repurchase agreements that provide for longer or shorter terms. The principal economic terms of each reverse repurchase agreement—such as loan amount, interest rate, and maturity date—are typically negotiated on a transaction-by-transaction basis. Other terms and conditions, such as those relating to events of default, are typically governed under the Company's master repurchase agreements. Absent an event of default, the Company maintains beneficial ownership of the transferred securities during the term of the reverse repurchase agreement and receives the related principal and interest payments. Interest rates on these borrowings are generally fixed based on prevailing rates corresponding to the terms of the borrowings, and for most reverse repurchase agreements, interest is generally paid at the termination of the reverse repurchase agreement, at which time the Company may enter into a new reverse repurchase agreement at prevailing market rates with the same counterparty, repay that counterparty and possibly negotiate financing terms with a different counterparty, or choose to no longer finance the related asset. Some reverse repurchase agreements provide for periodic payments of interest, such as monthly payments. In response to a decline in the fair value of the transferred securities, whether as a result of changes in market conditions, security paydowns, or other factors, reverse repurchase agreement counterparties will typically make a margin call, whereby the Company will be required to post additional securities and/or cash as collateral with the counterparty in order to re-establish the agreed-upon collateralization requirements. In the event of increases in fair value of the transferred securities, the Company can generally require the counterparty to post collateral with it in the form of cash or securities. The Company is generally permitted to sell or re-pledge any securities posted by the counterparty as collateral; however, upon termination of the reverse repurchase agreement, or other circumstance in which the counterparty is no longer required to post such margin, the Company must return to the counterparty the same security that had been posted. The contractual amount (loan amount) of the Company's reverse repurchase agreements approximates their fair value, as the debt is short-term in nature. At any given time, the Company seeks to have its outstanding borrowings under reverse repurchase agreements with several different counterparties in order to reduce the exposure to any single counterparty. The Company had outstanding borrowings under reverse repurchase agreements with twenty counterparties as of June 30, 2016 and eighteen counterparties as of December 31, 2015. At June 30, 2016 , approximately 17% of open reverse repurchase agreements were with one counterparty. At December 31, 2015, approximately 15% of open reverse repurchase agreements were with one counterparty. As of June 30, 2016 remaining days to maturity on the Company's open reverse repurchase agreements ranged from 1 day to 484 days and from 4 days to 666 days as of December 31, 2015. Interest rates on the Company's open reverse repurchase agreements ranged from 0.57% to 3.46% as of June 30, 2016 and from 0.37% to 2.92% as of December 31, 2015.

Not included above are reverse repurchase agreements that the Company may have entered into prior to period end for which delivery of the borrowed funds is not scheduled until after period end in the amount of $143 thousand and $4.4 million as of June 30, 2016 and December 31, 2015, respectively. As of June 30, 2016 and December 31, 2015, the fair value of investments transferred as collateral under outstanding borrowings under reverse repurchase agreements was $1.24 billion and $1.35 billion , respectively. Collateral transferred under outstanding borrowings as of June 30, 2016 include investments in the amount of $21.8 million that were sold prior to period end but for which such sale had not yet settled. In addition the Company posted net cash collateral of $35.4 million and additional securities with a fair value of $6.0 million as of June 30, 2016 to its counterparties. Collateral transferred under outstanding borrowings as of December 31, 2015 include investments in the amount of $16.8 million that were sold prior to period end but for which such sale had not yet settled. In addition, the Company posted net cash collateral of $25.5 million and additional securities with a fair value of $5.1 million as of December 31, 2015 as a result of margin calls from various counterparties. Securitized Debt In addition to its borrowings under reverse repurchase agreements, the Company has entered into a securitization transaction to finance certain of its commercial mortgage loans and REO which was accounted for as a collateralized borrowing. As of June 30, 2016 , the Company had outstanding borrowings in the amount of $13.0 million in connection with this securitization which is reflected under the caption "Securitized debt," on the Company's Consolidated Statement of Assets, Liabilities, and Equity. The Company did not have any outstanding borrowings classified as Securitized debt as of December 31, 2015. As of June 30, 2016 , the fair value of commercial mortgage loans and REO collateralizing this financing was $29.0 million . Interest accrues at a rate of LIBOR plus 3.25% and the debt has a maturity date of March 16, 2018. See Note 7 for further information on the Company's securitized debt.

Effective November 3, 2015, the Board of Directors approved a Sixth Amended and Restated Management Agreement, between the Company and the Manager. The descriptions of the Base Management Fees and Incentive Fees are detailed below. Base Management Fees The Operating Partnership pays the Manager 1.50% per annum of total equity of the Operating Partnership calculated in accordance with U.S. GAAP as of the end of each fiscal quarter (before deductions for base management fees and incentive fees payable with respect to such fiscal quarter), provided that total equity is adjusted to exclude one-time events pursuant to changes in U.S. GAAP, as well as non-cash charges after discussion between the Manager and the Company's independent directors, and approval by a majority of the Company's independent directors in the case of non-cash charges. Summary information —For the three month periods ended June 30, 2016 and 2015, the total base management fee incurred was $2.6 million and $2.9 million , respectively. For the six month periods ended June 30, 2016 and 2015, the total base management fee incurred was $5.2 million and $5.9 million , respectively. Incentive Fees The Manager is entitled to receive a quarterly incentive fee equal to the positive excess, if any, of (i) the product of (A) 25% and (B) the excess of (1) Adjusted Net Income (described below) for the Incentive Calculation Period (which means such fiscal quarter and the immediately preceding three fiscal quarters) over (2) the sum of the Hurdle Amounts (described below) for the Incentive Calculation Period, over (ii) the sum of the incentive fees already paid or payable for each fiscal quarter in the Incentive Calculation Period preceding such fiscal quarter. For purposes of calculating the incentive fee, "Adjusted Net Income" for the Incentive Calculation Period means the net increase in equity from operations of the Operating Partnership, after all base management fees but before any incentive fees for such period, and excluding any non-cash equity compensation expenses for such period, as reduced by any Loss Carryforward (as described below) as of the end of the fiscal quarter preceding the Incentive Calculation Period. For purposes of calculating the incentive fee, the "Loss Carryforward" as of the end of any fiscal quarter is calculated by determining the excess, if any, of (1) the Loss Carryforward as of the end of the immediately preceding fiscal quarter over (2) the Company's net increase in equity from operations (expressed as a positive number) or net decrease in equity from operations (expressed as a negative number) of the Operating Partnership for such fiscal quarter. As of June 30, 2016 there was a Loss Carryforward of $18.1 million . For purposes of calculating the incentive fee, the "Hurdle Amount" means, with respect to any fiscal quarter, the product of (i) one-fourth of the greater of (A) 9% and (B) 3% plus the 10-year U.S. Treasury rate for such fiscal quarter, (ii) the sum of (A) the weighted average gross proceeds per share of all common share and OP Unit issuances since inception of the Company and up to the end of such fiscal quarter, with each issuance weighted by both the number of shares and OP Units issued in such issuance and the number of days that such issued shares and OP Units were outstanding during such fiscal quarter, using a first-in first-out basis of accounting ( i.e. attributing any share and OP Unit repurchases to the earliest issuances first) and (B) the result obtained by dividing (I) retained earnings attributable to common shares and OP Units at the beginning of such fiscal quarter by (II) the average number of common shares and OP Units outstanding for each day during such fiscal quarter, (iii) the sum of the average number of common shares, LTIP Units, and OP Units outstanding for each day during such fiscal quarter. For purposes of determining the Hurdle Amount, issuances of common shares and OP Units (a) as equity incentive awards, (b) to the Manager as part of its base management fee or incentive fee and (c) to the Manager or any of its affiliates in privately negotiated transactions, are excluded from the calculation. The payment of the incentive fee will be in a combination of common shares and cash, provided that at least 10% of any quarterly payment will be made in common shares. Summary information —The Company did not incur any expense for incentive fees for either of the three or six month periods ended June 30, 2016 and 2015, since on a rolling four quarter basis, the Company's income did not exceed the prescribed hurdle amount. Termination Fees The Management Agreement requires the Company to pay a termination fee to the Manager in the event of (1) the Company's termination or non-renewal of the Management Agreement without cause or (2) the Company's termination of the Management Agreement based on unsatisfactory performance by the Manager that is materially detrimental to the Company (3) the Manager's termination of the Management Agreement upon a default by the Company in the performance of any material term of the Management Agreement. Such termination fee will be equal to the amount of three times the sum of (i) the average annual Quarterly Base Management Fee Amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal and (ii) the average annual Quarterly Incentive Fee Amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal. Expense Reimbursement Under the terms of the Management Agreement the Company is required to reimburse the Manager for operating expenses related to the Company that are incurred by the Manager, including expenses relating to legal, accounting, due diligence, other services, and all other costs and expenses. The Company's reimbursement obligation is not subject to any dollar limitation. Expenses will be reimbursed in cash within 60 days following delivery of the expense statement by the Manager; provided, however, that such reimbursement may be offset by the Manager against amounts due to the Company from the Manager. The Company will not reimburse the Manager for the salaries and other compensation of the Manager's personnel except that the Company will be responsible for expenses incurred by the Manager in employing certain dedicated or partially dedicated personnel as further described below. The Company reimburses the Manager for the allocable share of the compensation, including, without limitation, wages, salaries, and employee benefits paid or reimbursed, as approved by the Compensation Committee of the Board of Directors to certain dedicated or partially dedicated personnel who spend all or a portion of their time managing the Company's affairs, based upon the percentage of time devoted by such personnel to the Company's affairs. In their capacities as officers or personnel of the Manager or its affiliates, such personnel will devote such portion of their time to the Company's affairs as is necessary to enable the Company to operate its business. For the six month periods ended June 30, 2016 and 2015, the Company reimbursed the Manager $3.4 million and $2.0 million , respectively, for previously incurred operating and compensation expenses. Equity Investments in Certain Mortgage Originators The Company has non-controlling investments in the form of debt and equity in various mortgage originators. As of June 30, 2016 , of the mortgage originators that the Company has invested in, two represent related parties. Transactions that have been entered into with these related party mortgage originators are summarized below. In March 2015, the Company made an initial investment in a mortgage originator in the form of preferred and common stock. In addition, the Company entered into a flow mortgage loan purchase and sale agreement with the mortgage originator whereby the Company has committed to purchase eligible residential mortgage loans. See Note 15, Commitments and Contingencies, for further information on such flow agreement. The Company has also entered into a $3.0 million loan agreement for a warehouse facility with the mortgage originator. Under the terms of the facility, the Company has agreed to make advances to the mortgage originator solely for the purpose of funding residential mortgage loans designated for sale to the Company. To the extent the advances are drawn by the mortgage originator, it must pay interest, equal to LIBOR plus 5.00% , on the unpaid amount of each advance from the date the advance is made until such advance is paid in full. The mortgage originator is required to repay advances made in full no later than two business days following the date the Company purchases the loans from the mortgage originator. As of June 30, 2016 , there were $0.6 million in advances outstanding. In connection with its equity interest in another mortgage originator, the Company has entered into an agreement whereby it guarantees the performance of the mortgage originator under a third-party warehouse facility. The Company also has funded and caused a letter of credit to be issued by a bank for the benefit of this mortgage originator, in order to assist it in complying with its state licensing requirements. See Note 15, Commitments and Contingencies for further information on the Company's guarantee of the third party warehouse facility for the benefit of the mortgage originator. Investment in Affiliate The Company has investments in participation certificates related to consumer loans held in a trust owned by a related party of the Manager. Through its participation certificates, the Company has beneficial interests in the cash flows of the underlying loans held by such trust. The Company's investment in participation certificates in the amount of $6.0 million and $3.8 million as of June 30, 2016 and December 31, 2015, respectively, is included on the Company's Consolidated Condensed Schedule of Investments in Consumer Loans and Asset-backed Securities backed by Consumer Loans. Participation in Multi-Borrower Financing Facility The Company is a co-participant in an agreement with another entity managed by an affiliate of Ellington, or the "affiliated entity," in order to facilitate the financing of certain small balance commercial mortgage loans and REO owned by the Company and the affiliated entity, respectively (the "SBC Assets"). In connection with this financing, each of the Company and the affiliated entity transferred their respective SBC Assets to a jointly owned entity, which in turn transferred these assets to a securitization trust. In March 2016, the securitization trust issued $37.5 million in debt, collateralized by the SBC Assets, to a large financial institution. While the Company's SBC Assets were transferred to the securitization trust, the Company's SBC Assets and the related debt have not been derecognized for financial reporting purposes, because the Company continues to retain the risks and rewards of ownership of its SBC Assets. The debt issued by the trust amortizes over its original term of two years , and the Company's portion of this debt at issuance was $23.2 million . As of June 30, 2016 , the outstanding debt of the trust was $27.3 million and the Company's portion was $13.0 million and is reflected under the caption "Securitized debt," on the Company's Consolidated Statement of Assets, Liabilities, and Equity. To the extent there is a default under the financing arrangement, such as the insolvency of either the Company or the affiliated entity, the assets of the non-defaulting party could be used to satisfy outstanding obligations under the financing arrangement. As of June 30, 2016 , the affiliated entity was solvent.

Noncontrolling Interest [Abstract]
Noncontrolling Interest Disclosure [Text Block]	Non-controlling Interests Operating Partnership Non-controlling interests include the interest in the Operating Partnership owned by an affiliate of the Manager and certain related parties. On January 1, 2013, 212,000 OP Units were issued to the initial non-controlling interest member. Income allocated to the non-controlling interest is based on the non-controlling interest owners' ownership percentage of the Operating Partnership during the quarter, calculated using a daily weighted average of all common shares and convertible units outstanding during the quarter. Holders of OP Units are entitled to receive the same distributions that holders of common shares receive, and OP Units are convertible into common shares on a one-for-one basis, subject to specified limitations. OP Units are non-voting with respect to matters as to which common shareholders are entitled to vote. As of June 30, 2016 , non-controlling interest related to the outstanding 212,000 OP Units represented an interest of approximately 0.6% in the Operating Partnership. Joint Venture Interests Non-controlling interests also include the interests of joint venture partners in various consolidated subsidiaries of the Company. These subsidiaries hold the Company's investments in certain commercial mortgage loans and REO. These joint venture partners participate in these subsidiaries on a pari passu basis with the Company at a predetermined percentage, and therefore participate in all income, expense, gains and losses of such subsidiaries. These joint venture partners make capital contributions to the subsidiaries as new approved investments are purchased by the subsidiaries, and are generally entitled to distributions when investments are sold or otherwise disposed of. As of June 30, 2016 these joint venture partners' interests in subsidiaries of the Company were $0.8 million , representing an approximately 5% interest in such subsidiaries. These joint venture partners' interests are not convertible into common shares of the Company or OP Units, nor are these joint venture partners entitled to receive distributions that holders of common shares of the Company receive.

The following tables present information about certain assets and liabilities representing financial instruments as of June 30, 2016 and December 31, 2015. The Company has not entered into master netting agreements with any of its counterparties.

(3) When collateral is pledged to or pledged by a counterparty, it is often pledged or posted with respect to all positions with such counterparty, and in such cases such collateral cannot be specifically identified as relating to a specific asset or liability. As a result, in preparing the above tables, the Company has made assumptions in allocating pledged or posted collateral among the various rows.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	Commitments and Contingencies The Company provides current directors and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Company. In the normal course of business the Company may also enter into contracts that contain a variety of representations, warranties, and general indemnifications. The Company's maximum exposure under these arrangements, including future claims that may be made against the Company that have not yet occurred, is unknown. The Company has not incurred any costs to defend lawsuits or settle claims related to these indemnification agreements. The Company has no liabilities recorded for these agreements as of June 30, 2016 and December 31, 2015. The Company has entered into a purchase agreement whereby it has committed to purchase newly issued consumer loans originated by a third party over a term that was extended in November 2015 and expires in November 2016. As of June 30, 2016 , the Company's remaining purchase commitment in connection with the purchase agreement is $11.1 million in total principal balance. The Company has entered into a flow consumer loan purchase and sale agreement, open-ended in duration, with a third party whereby the Company has committed to purchase up to $100 million of eligible consumer loans. As of June 30, 2016 , the Company has purchased $89.1 million in eligible consumer loans under this agreement. In January 2016, the Company entered into a purchase agreement, open-ended in duration, with a third party whereby it has committed to purchase $375 million of principal balance of eligible consumer loans. As of June 30, 2016 , the Company has purchased $5.1 million of principal balance in eligible consumer loans under the agreement. In August 2015 the Company entered into participation and guarantee agreements, with terms expiring in August 2016, whereby: (i) the Company purchased a $10 million participation interest in a borrowing facility structured as a repurchase agreement, or "Repo Facility," between two parties unrelated to the Company, and (ii) the Company guarantees the borrower's payment obligations under the Repo Facility. The borrower may borrow up to $200 million under the Repo Facility, which is collateralized by residential mortgage loans which are required to be (1) eligible for guarantee by the Federal National Mortgage Association or the Federal Home Loan Mortgage Corporation, or (2) eligible for insurance by the Federal Housing Administration, or the U.S. Department of Veterans Affairs. To the extent the borrower performs under the Repo Facility over the term of the participation and guarantee agreements, the Company will be reimbursed in full its $10 million participation interest. Should the borrower default under the Repo Facility, the Company would be required to post to the lender an additional 5% of the then-outstanding amount borrowed under the Repo Facility and should the lender then exercise its rights under the guarantee, the Company could be required to purchase the mortgage loan collateral at a price equal to the aggregate amount borrowed under the Repo Facility, inclusive of accrued interest and any outstanding unused facility fees. In this case, the Company would have full recourse to the borrower to the extent of any deficit between the value of the mortgage loan collateral and the price paid by the Company for such collateral. The Company has the option, but not the obligation, to finance a specified portion of such purchase with the lender for up to six months via a pre-negotiated, committed repurchase facility. As a result of these agreements, the Company's risk is a function of the ongoing creditworthiness of the borrower and market value of the mortgage loan collateral in relation to the amount owed by the borrower under the Repo Facility. For its participation in this arrangement, the Company is paid monthly and quarterly fees based on the amount utilized under the Repo Facility. Fees received are included in "Other Income" on the Company's Consolidated Statement of Operations. The participation interest in the amount of $10 million is included in "Due from broker" on the Company's Consolidated Statement of Assets, Liabilities, and Equity. The Company's obligation under this arrangement is deemed to be a guaranty under ASC 460-10, Guarantees, and is carried at fair value and included in "Other Liabilities," on the Consolidated Statement of Assets, Liabilities, and Equity. As of June 30, 2016 the borrower utilized approximately $196.6 million under the Repo Facility and is performing on its obligations under such facility. The Company is considering renewing its participation in, and guarantee of, the Repo Facility upon its expiration. Commitments and Contingencies Related to Investments in Mortgage Originators As of June 30, 2016 , the Company had non-controlling investments in multiple mortgage originators. In connection with certain of its investments in such mortgage originators, the Company has outstanding commitments and contingencies as described below. In connection with its equity interest in a mortgage originator, as described in Note 7, Related Party Transactions, the Company has entered into an agreement whereby it guarantees the performance of the mortgage originator under a warehouse facility. As of June 30, 2016 , the Company's maximum guarantee was $12.5 million . The Company's obligation under this arrangement is deemed to be a guaranty under ASC 460-10, Guarantees, and is carried at fair value and included in "Other Liabilities," on the Consolidated Statement of Assets, Liabilities, and Equity. In March 2015, the Company made an initial investment in another mortgage originator in the form of preferred and common stock. As described in Note 7, Related Party Transactions, the Company entered into a flow mortgage loan purchase and sale agreement with the mortgage originator whereby the Company has committed to purchase eligible residential mortgage loans, to the extent they are originated in accordance with the Company's specifications, which it may modify in its sole discretion, in an amount of at least $200 million . The Company may opt to increase the amount purchased in its sole discretion based on its evaluation of mortgage loans previously purchased as well as market conditions. As of June 30, 2016 , the Company purchased loans under this agreement in the amount of $40.6 million .

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The Company's unaudited interim consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America, or "U.S. GAAP," for investment companies, ASC 946, Financial Services—Investment Companies ("ASC 946"). The Company has determined that it meets the definition of an investment company under ASC 946 . ASC 946 requires, among other things, that investments be reported at fair value in the financial statements. Additionally under ASC 946 the Company generally will not consolidate its interest in any company other than in its subsidiaries that qualify as investment companies under ASC 946. The consolidated financial statements include the accounts of the Company, the Operating Partnership, and its subsidiaries. All intercompany balances and transactions have been eliminated. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In management's opinion, all material adjustments, considered necessary for a fair presentation of the Company's interim consolidated financial statements have been included and are only of a normal recurring nature. Interim results are not necessarily indicative of the results that may be expected for the entire fiscal year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2015.
Valuation	Valuation: The Company applies ASC 820-10, Fair Value Measurement and Disclosures ("ASC 820-10"), to its holdings of financial instruments. ASC 820-10 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the observability of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: • Level 1—inputs to the valuation methodology are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Currently, the types of financial instruments the Company generally includes in this category are listed equities, exchange-traded derivatives, and cash equivalents; • Level 2—inputs to the valuation methodology other than quoted prices included in Level 1 are observable for the asset or liability, either directly or indirectly. Currently, the types of financial instruments that the Company generally includes in this category are Agency RMBS, non-Agency mortgage-backed securities determined to have sufficiently observable market data, U.S. Treasury securities and certain sovereign debt, commonly traded derivatives, such as interest rate swaps and foreign currency forwards, and certain other over-the-counter derivatives; and • Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement. The types of financial instruments that the Company generally includes in this category are RMBS, CMBS, ABS, credit default swaps, or "CDS," on individual ABS, distressed corporate debt, and total return swaps on distressed corporate debt, in each case where there is less price transparency. Also included in this category are residential and commercial mortgage loans, consumer loans, non-listed equities, and private corporate debt and equity investments. For certain financial instruments, the various inputs that management uses to measure fair value for such financial instrument may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for such financial instrument is based on the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the various inputs that management uses to measure fair value with the highest priority to inputs that are observable and reflect quoted prices (unadjusted) for identical assets or liabilities in active markets (Level 1) and the lowest priority to inputs that are unobservable and significant to the fair value measurement (Level 3). The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. The Company may use valuation techniques consistent with the market and income approaches to measure the fair value of its assets and liabilities. The market approach uses third-party valuations and information obtained from market transactions involving identical or similar assets or liabilities. The income approach uses projections of the future economic benefit of an instrument to determine its fair value, such as in the discounted cash flow methodology. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risk associated with investing in these financial instruments. Transfers between levels of the fair value hierarchy are assumed to occur at the end of the reporting period. Summary Valuation Techniques For financial instruments that are traded in an "active market," the best measure of fair value is the quoted market price. However, many of the Company's financial instruments are not traded in an active market. Therefore, management generally uses third-party valuations when available. If third-party valuations are not available, management uses other valuation techniques, such as the discounted cash flow methodology. The following are summary descriptions, for various categories of financial instruments, of the valuation methodologies management uses in determining fair value of the Company's financial instruments in such categories. Management utilizes such methodologies to assign a good faith fair value (the estimated price that, in an orderly transaction at the valuation date, would be received to sell an asset, or paid to transfer a liability, as the case may be) to each such financial instrument. For mortgage-backed securities, or "MBS," including To Be Announced MBS, or "TBAs," CLOs, and distressed and non-distressed corporate debt and equity, management seeks to obtain at least one third-party valuation, and often obtains multiple valuations when available. Management has been able to obtain third-party valuations on the vast majority of these instruments and expects to continue to solicit third-party valuations in the future. Management generally values each financial instrument at the average of third-party valuations received and not rejected as described below. Third-party valuations are not binding, and while management generally does not adjust the valuations it receives, management may challenge or reject a valuation when, based on its validation criteria, management determines that such valuation is unreasonable or erroneous. Furthermore, based on its validation criteria, management may determine that the average of the third-party valuations received for a given instrument does not result in what management believes to be the fair value of such instrument, and in such circumstances management may override this average with its own good faith valuation. The validation criteria may take into account output from management's own models, recent trading activity in the same or similar instruments, and valuations received from third parties. The use of proprietary models requires the use of a significant amount of judgment and the application of various assumptions including, but not limited to, assumptions concerning future prepayment rates and default rates. Valuations for fixed rate MBS pass-throughs issued by a U.S. government agency or government-sponsored enterprise are typically based on observable pay-up data (pay-ups are price premiums for specified categories of fixed rate pools relative to their TBA counterparts) or models that use observable market data, such as interest rates and historical prepayment speeds, and are validated against third-party valuations. Given their relatively high level of price transparency, Agency RMBS pass-throughs are typically designated as Level 2 assets, although Agency interest only and inverse interest only RMBS are currently designated as Level 3 assets since they generally have less price transparency. Non-Agency MBS and CLOs are generally classified as either Level 2 or Level 3 based on analysis of available market data such as recent trades and executable bids. The Company's investments in distressed corporate debt are in the form of loans as well as total return swaps on loans. Valuations are typically based on prices of the underlying loans received from widely used third-party pricing services. These investments as well as related non-listed equity investments are generally designated as Level 3 assets. Furthermore, the methodology used by the third-party valuation providers is reviewed at least annually by management, so as to ascertain whether such providers are utilizing observable market data to determine the valuations that they provide. For residential and commercial mortgage loans, consumer loans, and real estate owned properties, or "REO," management determines fair value by taking into account both external pricing data, when available, and internal pricing models. Non-performing mortgage loans and REO are typically valued based on management's estimates of the value of the underlying real estate, using various information including general economic data, broker price opinions, or "BPOs," recent sales, property appraisals, and bids. Performing mortgage loans and consumer loans are typically valued using discounted cash flows based on market assumptions and non-QM residential mortgage loans are valued using matrix pricing. Cash flow assumptions typically include projected default and prepayment rates and loss severities, and may include adjustments based on appraisals and BPOs. Mortgage and consumer loans and REO properties are classified as Level 3 assets. For financial derivatives with greater price transparency, such as CDS on asset-backed indices, CDS on corporate indices, certain options on the foregoing, and total return swaps on publicly-traded equities, market-standard pricing sources are used to obtain valuations; these financial derivatives are generally designated as Level 2 instruments. Interest rate swaps, swaptions, and foreign currency forwards are typically valued based on internal models that use observable market data, including applicable interest rates and foreign currency rates in effect as of the measurement date; the model-generated valuations are then typically compared to counterparty valuations for reasonableness. These financial derivatives are also generally designated as Level 2 instruments. Financial derivatives with less price transparency, such as CDS on individual ABS, are generally valued based on internal models, and are typically designated as Level 3 instruments. In the case of CDS on individual ABS, the valuation process typically starts with an estimation of the value of the underlying ABS. In valuing its derivatives, the Company also considers the creditworthiness of both the Company and its counterparties, along with collateral provisions contained in each derivative agreement. Investments in private operating entities, such as mortgage originators, are valued based on available metrics, such as relevant market multiples and comparable company valuations, and company specific-financial data including actual and projected results. These investments are designated as Level 3 assets. The Company's repurchase agreements are carried at fair value based on their contractual amounts as the debt is short-term in nature. The Company's reverse repurchase agreements are carried at cost, which approximates fair value. Repurchase and reverse repurchase agreements are classified as Level 2 assets and liabilities based on the adequacy of the collateral and their short term nature. The Company's valuation process, including the application of validation criteria, is overseen by the Manager's Valuation Committee ("Valuation Committee"). The Valuation Committee includes senior level executives from various departments within the Manager, and each quarter, the Valuation Committee reviews and approves the valuations of the Company's investments. The valuation process also includes a monthly review by the Company's third-party administrator. The goal of this review is to replicate various aspects of the Company's valuation process based on the Company's documented procedures. Because of the inherent uncertainty of valuation, the estimated fair value of the Company's financial instruments may differ significantly from the values that would have been used had a ready market for the financial instruments existed, and the differences could be material to the Company's consolidated financial statements.
Purchase and Sales of Investments and Investment Income	Purchase and Sales of Investments and Investment Income: Purchases and sales of investments are generally recorded on trade date, and realized and unrealized gains and losses are calculated based on identified cost. The Company amortizes premiums and accretes discounts on its debt investments. Coupon interest income on fixed income investments is generally accrued based on the outstanding principal balance or notional amount and the current coupon interest rate. For Agency RMBS and debt securities that are deemed to be of high credit quality at the time of purchase, premiums and discounts are amortized into interest income over the life of such securities using the effective interest method. For securities whose cash flows vary depending on prepayments, an effective yield retroactive to the time of purchase is periodically recomputed based on actual prepayments and changes in projected prepayment activity, and a catch-up adjustment is made to amortization to reflect the cumulative impact of the change in effective yield. For debt securities (including non-Agency MBS) that are deemed not to be of high credit quality at the time of purchase, interest income is recognized based on the effective interest method. For purposes of determining the effective interest rate, management estimates the future expected cash flows of its investment holdings based on assumptions including, but not limited to, assumptions for future prepayment rates, default rates, and loss severities (each of which may in turn incorporate various macro-economic assumptions, such as future housing prices). These assumptions are re-evaluated not less than quarterly. Principal write-offs are generally treated as realized losses. Changes in projected cash flows, as applied to the current amortized cost of the security, may result in a prospective change in the yield/interest income recognized on such securities. For each loan purchased with the expectation that both interest and principal will be paid in full, the Company generally amortizes or accretes any premium or discount over the life of the loan utilizing the effective interest method. However, on at least a quarterly basis based on current information and events, the Company re-assesses the collectability of interest and principal, and designates a loan as impaired either when any payments have become 90 or more days past due, or when, in the opinion of management, it is probable that the Company will be unable to collect either interest or principal in full. Once a loan is designated as impaired, as long as principal is still expected to be collectable in full, interest payments are recorded as interest income only when received (i.e., under the cash basis method); accruals of interest income are only resumed when the loan becomes contractually current and performance is demonstrated to be resumed. However, if principal is not expected to be collectable in full, the cost recovery method is used (i.e., no interest income is recognized, and all payments received—whether contractually interest or principal—are applied to cost). For each loan purchased with evidence of credit deterioration since origination and the expectation that either principal or interest will not be paid in full, interest income is generally recognized using the effective interest method for as long as the cash flows can be reasonably estimated. Here, instead of amortizing the purchase discount (i.e., the excess of the unpaid principal balance over the purchase price) over the life of the loan, the Company effectively amortizes the accretable yield (i.e., the excess of the Company's estimate of the total cash flows to be collected over the life of the loan over the purchase price). Not less than quarterly, the Company updates its estimate of the cash flows expected to be collected over the life of the loan, and revised yields are prospectively applied. To the extent that cash flows cannot be reasonably estimated, these loans are generally accounted for under the cost recovery method. For certain groups of consumer loans that the Company considers as having sufficiently homogeneous characteristics, the Company aggregates such loans into pools, and accounts for each such pool as a single asset. The pool is then treated analogously to a debt security deemed not to be of high credit quality, in that (i) the aggregate premium or discount for the pool is amortized or accreted into interest income based on the pool's effective interest rate; (ii) the effective interest rate is determined based on the net expected cash flows of the pool, taking into account estimates of prepayments, defaults, and loss severities; and (iii) estimates are updated not less than quarterly and revised yields are prospectively applied. In estimating future cash flows on the Company's debt investments, there are a number of assumptions that will be subject to significant uncertainties and contingencies, including, in the case of MBS, assumptions relating to prepayment rates, default rates, loan loss severities, and loan repurchases. These estimates require the use of a significant amount of judgment. The Company receives dividend income on certain of its equity investments and rental income on certain of its REO properties. These items of income are included on the Consolidated Statement of Operations under the heading, "Other income."
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash and cash equivalents include cash and short term investments with original maturities of three months or less at the date of acquisition. Cash and cash equivalents typically include amounts held in an interest bearing overnight account and amounts held in money market funds, and these balances generally exceed insured limits. The Company holds its cash at institutions that it believes to be highly creditworthy. Restricted cash represents cash that the Company can use only for specific purposes. See Note 13 for further discussion of restricted cash balances.
Financial Derivatives	Financial Derivatives: The Company enters into various types of financial derivatives. The Company's financial derivatives are predominantly subject to bilateral collateral arrangements or clearing in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. The Company may be required to deliver or receive cash or securities as collateral upon entering into derivative transactions. In addition, changes in the relative value of derivative transactions may require the Company or the counterparty to post or receive additional collateral. In the case of cleared derivatives, the clearinghouse becomes the Company's counterparty and a futures commission merchant acts as an intermediary between the Company and the clearinghouse with respect to all facets of the related transaction, including the posting and receipt of required collateral. Cash collateral received by the Company is reflected on the Consolidated Statement of Assets, Liabilities, and Equity as "Due to Brokers." Conversely, cash collateral posted by the Company is reflected as "Due from Brokers" on the Consolidated Statement of Assets, Liabilities, and Equity. The major types of derivatives utilized by the Company are swaps, futures, options, and forwards. Swaps: The Company may enter into various types of swaps, including interest rate swaps, credit default swaps, and total return swaps. The primary risk associated with the Company's interest rate swap activity is interest rate risk. The primary risk associated with the Company's credit default swaps is credit risk and the primary risks associated with the Company's total return swap activity are equity market risk and credit risk. The Company is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Primarily to help mitigate interest rate risk, the Company enters into interest rate swaps. Interest rate swaps are contractual agreements whereby one party pays a floating interest rate on a notional principal amount and receives a fixed rate payment on the same notional principal, or vice versa, for a fixed period of time. Interest rate swaps change in value with movements in interest rates. The Company enters into credit default swaps. A credit default swap is a contract under which one party agrees to compensate another party for the financial loss associated with the occurrence of a "credit event" in relation to a "reference amount" or notional value of a credit obligation (usually a bond, loan, or a basket of bonds or loans). The definition of a credit event may vary from contract to contract. A credit event may occur (i) when the underlying reference asset(s) fails to make scheduled principal or interest payments to its holders, (ii) with respect to credit default swaps referencing mortgage/asset-backed securities and indices, when the underlying reference obligation is downgraded below a certain rating level, or (iii) with respect to credit default swaps referencing corporate entities and indices, upon the bankruptcy of the underlying reference obligor. The Company typically writes (sells) protection to take a "long" position or purchases (buys) protection to take a "short" position with respect to underlying reference assets or to hedge exposure to other investment holdings. The Company enters into total return swaps in order to take a "long" or "short" position with respect to an underlying reference asset. The Company is subject to market price volatility of the underlying reference asset. A total return swap involves commitments to pay interest in exchange for a market-linked return based on a notional value. To the extent that the total return of the corporate debt, security, group of securities or index underlying the transaction exceeds or falls short of the offsetting interest obligation, the Company will receive a payment from or make a payment to the counterparty. Swaps change in value with movements in interest rates, credit quality, or total return of the reference securities. During the term of swap contracts, changes in value are recognized as unrealized gains or losses. When a contract is terminated, the Company realizes a gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Company's basis in the contract, if any. Periodic payments or receipts required by swap agreements are recorded as unrealized gains or losses when accrued and realized gains or losses when received or paid. Upfront payments paid and/or received by the Company to open swap contracts are recorded as an asset and/or liability on the Consolidated Statement of Assets, Liabilities, and Equity and are recorded as a realized gain or loss on the termination date. Futures Contracts: A futures contract is an exchange-traded agreement to buy or sell an asset for a set price on a future date. The Company enters into Eurodollar and/or U.S. Treasury security futures contracts to hedge its interest rate risk. The Company may also enter into various other futures contracts, including equity index futures. Initial margin deposits are made upon entering into futures contracts and can generally be either in the form of cash or securities. During the period the futures contract is open, changes in the value of the contract are recognized as unrealized gains or losses by marking-to-market to reflect the current market value of the contract. Variation margin payments are made or received periodically, depending upon whether unrealized losses or gains are incurred. When the contract is closed, the Company records a realized gain or loss equal to the difference between the proceeds of the closing transaction and the Company's basis in the contract. Options: The Company may purchase or write put or call options contracts or enter into swaptions. The Company enters into options contracts typically to help mitigate overall market, credit, or interest rate risk depending on the type of options contract. However, the Company also enters into options contracts from time to time for speculative purposes. When the Company purchases an options contract, the option asset is initially recorded at an amount equal to the premium paid, if any, and is subsequently marked-to-market. Premiums paid for purchasing options contracts that expire unexercised are recognized on the expiration date as realized losses. If an options contract is exercised, the premium paid is subtracted from the proceeds of the sale or added to the cost of the purchase to determine whether the Company has realized a gain or loss on the related transaction. When the Company writes an options contract, the option liability is initially recorded at an amount equal to the premium received, if any, and is subsequently marked-to-market. Premiums received for writing options contracts that expire unexercised are recognized on the expiration date as realized gains. If an options contract is exercised, the premium received is subtracted from the cost of the purchase or added to the proceeds of the sale to determine whether the Company has realized a gain or loss on the related investment transaction. When the Company enters into a closing transaction, the Company will realize a gain or loss depending upon whether the amount from the closing transaction is greater or less than the premiums paid or received. The Company may also enter into options contracts that contain forward-settling premiums. In this case, no money is exchanged upfront. Instead the agreed-upon premium is paid by the buyer upon expiration of the option, regardless of whether or not the option is exercised. Forward Currency Contracts: A forward currency contract is an agreement between two parties to purchase or sell a specific quantity of currency with the delivery and settlement at a specific future date and exchange rate. During the period the forward currency contract is open, changes in the value of the contract are recognized as unrealized gains or losses. When the contract is settled, the Company records a realized gain or loss equal to the difference between the proceeds of the closing transaction and the Company's basis in the contract. Commitments to Purchase Residential Mortgage Loans: The Company enters into forward purchase commitments under flow agreements, whereby the Company commits to purchasing the loans based on pre-defined underwriting guidelines and at stated interest rates. Actual loan purchases are contingent upon successful loan closings. These commitments to purchase mortgage loans are classified as derivatives on the Company's Consolidated Statement of Assets, Liabilities, and Equity and are, therefore, recorded as assets or liabilities measured at fair value. Until the purchase commitment expires or the underlying loan closes, changes in the estimated fair value of such commitments are recognized as unrealized gains or losses in the Consolidated Statement of Operations. Financial derivatives disclosed on the Consolidated Condensed Schedule of Investments include: credit default swaps on asset-backed securities, credit default swaps on asset-backed indices, credit default swaps on corporate bond indices, credit default swaps on corporate bonds, interest rate swaps, total return swaps, futures contracts, foreign currency forwards, options contracts, warrants, and mortgage loan purchase commitments. Financial derivative assets are included in Financial derivatives—assets, at fair value on the Consolidated Statement of Assets, Liabilities, and Equity. Financial derivative liabilities are included in Financial derivatives—liabilities, at fair value on the Consolidated Statement of Assets, Liabilities, and Equity. In addition, financial derivative contracts are summarized by type on the Consolidated Condensed Schedule of Investments.
Investments Sold Short	Investments Sold Short: When the Company sells securities short, it typically satisfies its security delivery settlement obligation by obtaining the security sold short from the same or a different counterparty. The Company generally is required to deliver cash or securities as collateral to the counterparty for the Company's obligation to return the borrowed security. The amount by which the market value of the obligation falls short of or exceeds the proceeds from the short sale is treated as an unrealized gain or loss, respectively. A realized gain or loss will be recognized upon the termination of a short sale if the market price is less or greater than the proceeds originally received.
Reverse Repurchase Agreements	Reverse Repurchase Agreements: The Company enters into reverse repurchase agreements with third-party broker-dealers whereby it sells securities under agreements to be repurchased at an agreed-upon price and date. The Company accounts for reverse repurchase agreements as collateralized borrowings, with the initial sale price representing the amount borrowed, and with the future repurchase price consisting of the amount borrowed plus interest, at the implied interest rate of the reverse repurchase agreement, on the amount borrowed over the term of the reverse repurchase agreement. The interest rate on a reverse repurchase agreement is based on competitive rates (or competitive market spreads, in the case of agreements with floating interest rates) at the time such agreement is entered into. When the Company enters into a reverse repurchase agreement, the lender establishes and maintains an account containing cash and/or securities having a value not less than the repurchase price, including accrued interest, of the reverse repurchase agreement. Reverse repurchase agreements are carried at their contractual amounts, which approximate fair value as the debt is short-term in nature.
Repurchase Agreements	Repurchase Agreements: The Company enters into repurchase agreement transactions with third-party broker-dealers whereby it purchases securities under agreements to resell at an agreed-upon price and date. In general, securities received pursuant to repurchase agreements are delivered to counterparties of short sale transactions. The interest rate on a repurchase agreement is based on competitive rates (or competitive market spreads, in the case of agreements with floating interest rates) at the time such agreement is entered into. Assets held pursuant to repurchase agreements are reflected as assets on the Consolidated Statement of Assets, Liabilities, and Equity. Repurchase agreements are carried at fair value based on their contractual amounts as the debt is short-term in nature. Repurchase and reverse repurchase agreements that are conducted with the same counterparty may be reported on a net basis if they meet the requirements of ASC 210-20, Balance Sheet Offsetting .
Securitized Debt	Securitized Debt: The Company entered into a securitization transaction in March 2016 to finance certain of its commercial mortgage loans and REO which was accounted for as a collateralized borrowing. The assets contributed to the securitization were not derecognized but rather, the liability issued by the securitization was recorded to reflect the financing of the securitized assets. Debt issuance costs associated with the securitized debt are amortized over the life of the securitized debt and included in interest expense.
When-Issued/Delayed Delivery Securities	When-Issued/Delayed Delivery Securities: The Company may purchase or sell securities on a when-issued or delayed delivery basis. Securities purchased or sold on a when-issued basis are traded for delivery beyond the normal settlement date at a stated price or yield, and no income accrues to the purchaser prior to settlement. Purchasing or selling securities on a when-issued or delayed delivery basis involves the risk that the market price or yield at the time of settlement may be lower or higher than the agreed-upon price or yield, in which case a realized loss may be incurred. The Company transacts in the forward settling TBA market. The Company typically does not take delivery of TBAs, but rather settles the associated receivable and payable with its trading counterparties on a net basis. Transactions with the same counterparty for the same TBA that result in a reduction of the position are treated as extinguished. The market value of the securities that the Company is required to purchase pursuant to a TBA transaction may decline below the agreed-upon purchase price. Conversely, the market value of the securities that the Company is required to sell pursuant to a TBA transaction may increase above the agreed upon sale price. As part of its TBA activities, the Company may "roll" its TBA positions, whereby the Company may sell (buy) securities for delivery (receipt) in an earlier month and simultaneously contract to repurchase (sell) similar, but not identical, securities at an agreed-upon price on a fixed date in a later month (with the later-month price typically lower than the earlier-month price). The Company accounts for its TBA transactions (including those related to TBA rolls) as purchases and sales.
REO	REO: When the Company obtains possession of real property in connection with a foreclosure or similar action, the Company de-recognizes the associated mortgage loan according to ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure ("ASU 2014-04"). Under the provisions of ASU 2014-04, the Company is deemed to have received physical possession of real estate property collateralizing a mortgage loan when it obtains legal title to the property upon completion of a foreclosure or when the borrower conveys all interest in the property to it through a deed in lieu of foreclosure or similar legal agreement. The Company holds all REO at fair value.
Investments in Operating Entities	Investments in Operating Entities: The Company has made and may in the future make non-controlling investments in operating entities such as mortgage originators. Investments in such operating entities may be in the form of preferred and/or common equity, debt, or some other form of investment. The Company carries its investments in such entities at fair value. The impact of these investments and their results of operations are immaterial to the Company's financial condition and results of operations. In such cases the Company has applied the equity method of accounting to such equity investments and has elected to fair value such investments under the fair value option within ASC 825.
Offering Costs/Underwriters' Discount	Offering Costs/Underwriters' Discount: Offering costs and underwriters' discount are charged against shareholders' equity. Offering costs typically include legal, accounting, printing, and other fees associated with the cost of raising capital.
Expenses [Policy Text Block]	Expenses: Expenses are recognized as incurred on the Consolidated Statement of Operations.
Other Investment Related Expenses [Policy Text Block]	Other Investment Related Expenses: Other investment related expenses consist of expenses directly related to specific financial instruments. Such expenses generally include dividend expense on common stock sold short, servicing fees and corporate and escrow advances on mortgage and consumer loans, and various other expenses and fees related directly to the Company's financial instruments. Other investment related expenses are generally recognized as incurred on the Consolidated Statement of Operations; dividend expense on common stock sold short is recognized on the ex-dividend date.
LTIP Units	LTIP Units: Long term incentive plan units ("LTIP units") have been issued to the Company's dedicated or partially dedicated personnel and independent directors as well as the Manager. Costs associated with LTIP units issued to dedicated or partially dedicated personnel, or to independent directors, are measured as of the grant date based on the closing stock price on the New York Stock Exchange and are amortized over the vesting period in accordance with ASC 718-10, Compensation—Stock Compensation . The vesting periods for LTIP units issued under the Ellington Incentive Plan for Individuals (the "Individual LTIP") are typically one year for independent directors, and are typically one year to two years for dedicated or partially dedicated personnel.
Non-controlling interest	Non-controlling interests : Non-controlling interests include the interest in the Operating Partnership owned by an affiliate of the Manager and certain related parties and consist of units convertible into the Company's common shares. Non-controlling interests also include the interests of joint venture partners in certain of our consolidated subsidiaries. The joint venture partners' interests do not consist of units convertible into the Company's common shares. The Company adjusts the non-controlling interests owned by an affiliate of the Manager and certain related parties to align their carrying value with the share of total outstanding operating partnership units ("OP Units") issued by the Operating Partnership to the non-controlling interest. Any such adjustments are reflected in "Adjustment to non-controlling interest" on the Consolidated Statement of Changes in Equity. See Note 9 for further discussion of non-controlling interests.
Dividends	Dividends: Dividends payable by the Company are recorded on the ex-dividend date. Dividends are typically declared and paid on a quarterly basis in arrears.
Shares Repurchased	Shares Repurchased: Common shares that are repurchased by the Company subsequent to issuance are immediately retired upon settlement and decrease the total number of shares outstanding and issued.
Earnings Per Share ("EPS")	Earnings Per Share ("EPS"): Basic EPS is computed using the two class method by dividing net increase (decrease) in shareholders' equity resulting from operations after adjusting for the impact of LTIP units which are participating securities, by the weighted average number of common shares outstanding calculated including LTIP units. Because the Company's LTIP units are participating securities, they are included in the calculation of basic and diluted EPS. OP Units relating to a non-controlling interest are also participating securities and, accordingly, are included in the calculation of both basic and diluted EPS.
Foreign Currency	Foreign Currency: Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at current exchange rates at the following dates: (i) assets, liabilities, and unrealized gains/losses—at the valuation date; and (ii) income, expenses, and realized gains/losses—at the accrual/transaction date. The Company isolates the portion of realized and change in unrealized gain (loss) resulting from changes in foreign currency exchange rates on investments and financial derivatives from the fluctuations arising from changes in fair value of investments and financial derivatives held. Changes in realized and change in unrealized gain (loss) due to foreign currency are included in Foreign currency transactions and Foreign currency translation, respectively, on the Consolidated Statement of Operations.
Income Taxes	Income Taxes: The Company has been and continues to expect to be treated as a partnership for U.S. federal income tax purposes. Certain of the Company's subsidiaries are not consolidated for U.S. federal income tax purposes, but are also treated as partnerships. In general, partnerships are not subject to entity-level tax on their income, but the income of a partnership is taxable to its owners on a flow-through basis. In addition, certain subsidiaries of the Company have elected to be treated as corporations for U.S. federal income tax purposes, and one intends to elect to be taxed as a real estate investment trust, or "REIT", beginning with the tax year ending December 31, 2015. Upon this entity's filing of its 2015 tax return in the fall of 2016, it will formally make the election to be taxed as a REIT. The Company follows the provisions of ASC 740-10, Income Taxes ("ASC 740-10"), which requires management to determine whether a tax position of the Company is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals, based on the technical merits of the position. The Company did not have any additions to unrecognized tax benefits resulting from tax positions related either to the current period or to 2015, 2014, 2013, or 2012 (its open tax years), and no reductions resulting from tax positions of prior years or due to settlements, and thus had no unrecognized tax benefits or reductions since inception. The Company does not expect any change in unrecognized tax benefits within the next fiscal year. There were no amounts accrued for tax penalties or interest as of or during the periods presented in these consolidated financial statements. The Company may take positions with respect to certain tax issues which depend on legal interpretation of facts or applicable tax regulations. Should the relevant tax regulators successfully challenge any of such positions, the Company might be found to have a tax liability that has not been recorded in the accompanying consolidated financial statements. Also, management's conclusions regarding ASC 740-10 may be subject to review and adjustment at a later date based on factors including, but not limited to, further implementation guidance from the Financial Accounting Standards Board, or "FASB," and ongoing analyses of tax laws, regulations and interpretations thereof.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern ("ASU 2014-15"). ASU 2014-15 requires management to perform interim and annual assessments of an entity's ability to continue as a going concern and to provide disclosure if events or conditions arise that would place substantial doubt on the entity's ability to continue as a going concern. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and subsequent interim and annual periods with early adoption permitted. The adoption of ASU 2014-15 is not expected to have a material impact on the Company's consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02"). This amends ASC 810, Consolidation (ASC "810"), to improve targeted areas of consolidation guidance by simplifying the requirements of consolidation and placing more emphasis on risk of loss when determining a controlling financial interest. ASU 2015-02 is effective for annual and interim periods beginning after December 15, 2015, with early adoption permitted. The adoption of ASU 2015-02 did not have a material impact on the Company's consolidated financial statements.

The table above incorporates changes in net unrealized gain (loss) for both Level 3 financial instruments held by the Company at June 30, 2016 , as well as Level 3 financial instruments disposed of by the Company during the three month period ended June 30, 2016 . For Level 3 financial instruments held by the Company at June 30, 2016 , change in net unrealized gain (loss) of $(2.2) million , $(0.03) million , $0.3 million , $(0.6) million , and $0.3 million , for the three month period ended June 30, 2016 relate to investments, investments sold short, financial derivatives–assets, financial derivatives–liabilities, and guarantees, respectively. As of June 30, 2016 , the Company transferred $8.8 million of non-Agency RMBS from Level 3 to Level 2. These assets were transferred from Level 3 to Level 2 based on an increased volume of observed trading of these and similar assets. This increase in observed trading activity has led to greater price transparency for these assets, thereby making a Level 2 designation appropriate in the Company's view. However, changes in the volume of observable inputs for these assets, such as a decrease in the volume of observed trading, could impact price transparency, and thereby cause a change in the level designation for these assets in future periods. In addition, as of June 30, 2016 , the Company transferred $12.8 million of non-Agency RMBS from Level 2 to Level 3. Since March 31, 2016, these securities have exhibited indications of a reduced level of price transparency. Examples of such indications include wider spreads relative to similar securities and a reduction in observable transactions involving these and similar securities. Changes in these indications could impact price transparency, and thereby cause a change in the level designation in future periods.

The table above incorporates changes in net unrealized gain (loss) for both Level 3 financial instruments held by the Company at June 30, 2015 , as well as Level 3 financial instruments disposed of by the Company during the six month period ended June 30, 2015 . For Level 3 financial instruments held by the Company at June 30, 2015 , change in net unrealized gain (loss) of $(1.0) million , $1.0 million , $(1.9) million , and $0.02 million for the six month period ended June 30, 2015 relate to investments, financial derivatives–assets, financial derivatives–liabilities, and securitized debt, respectively. As of June 30, 2015 , the Company transferred $77.6 million of non-Agency RMBS from Level 3 to Level 2. These assets were transferred from Level 3 to Level 2 based on an increased volume of observed trading of these and similar assets. This increase in observed trading activity has led to greater price transparency for these assets, thereby making a Level 2 designation appropriate in the Company's view. However, changes in the volume of observable inputs for these assets, such as a decrease in the volume of observed trading, could impact price transparency, and thereby cause a change in the level designation for these assets in future periods. In addition, as of June 30, 2015 , the Company transferred $6.5 million of non-Agency RMBS from Level 2 to Level 3. Following December 2014, these securities have exhibited indications of a reduced level of price transparency. Examples of such indications include wider spreads relative to similar securities and a reduction in observable transactions involving these and similar securities. Changes in these indications could impact price transparency, and thereby cause a change in the level designation in future periods.

(2) The notional value is the maximum amount that a seller of credit protection would be obligated to pay, and a buyer of credit protection would receive upon occurrence of a "credit event." Movements in the value of credit default swap transactions may require the Company or the counterparty to post or receive collateral. Amounts due or owed under credit derivative contracts with an International Swaps and Derivatives Association, or "ISDA," counterparty may be offset against amounts due or owed on other credit derivative contracts with the same ISDA counterparty. As a result, the notional amount of written credit derivatives involving a particular underlying reference asset or index has been reduced (but not below zero) by the notional amount of any contracts where the Company has purchased credit protection on the same reference asset or index with the same ISDA counterparty.

The Company has not entered into master netting agreements with any of its counterparties. Certain of the Company's repurchase and reverse repurchase agreements and financial derivative transactions are governed by underlying agreements that generally provide a right of offset in the event of default or in the event of a bankruptcy of either party to the transaction. June 30, 2016 : Description Gross Amounts of Assets (Liabilities) in the Consolidated Statement of Assets, Liabilities, and Equity Gross Amounts Offset in the Consolidated Statement of Assets, Liabilities, and Equity Amount of Assets (Liabilities) Presented in the Consolidated Statements of Assets, Liabilities, and Equity (1) Financial Instruments Available for Offset Financial Instruments Transferred or Pledged as Collateral (2)(3) Cash Collateral (Received) Pledged (2)(3) Net Amount (In thousands) Assets Financial derivatives–assets $ 152,628 $ — $ 152,628 $ (37,919 ) $ — $ (75,676 ) $ 39,033 Repurchase agreements 129,993 (13,990 ) 116,003 (116,003 ) — — — Liabilities Financial derivatives–liabilities (74,098 ) — (74,098 ) 37,919 — 36,179 — Reverse repurchase agreements (1,083,940 ) 13,835 (1,070,105 ) 116,003 950,974 3,128 — December 31, 2015: Description Amount of Assets (Liabilities) Presented in the Consolidated Statements of Assets, Liabilities, and Equity (1) Financial Instruments Available for Offset Financial Instruments Transferred or Pledged as Collateral (2)(3) Cash Collateral (Received) Pledged (2)(3) Net Amount (In thousands) Assets Financial derivatives–assets $ 162,905 $ (18,644 ) $ — $ (105,202 ) $ 39,059 Repurchase agreements 105,700 (105,700 ) — — — Liabilities Financial derivatives–liabilities (60,472 ) 18,644 — 41,699 (129 ) Reverse repurchase agreements (1,174,189 ) 105,700 1,042,947 25,542 — (1) In the Company's Consolidated Statement of Assets, Liabilities, and Equity, all balances associated with repurchase agreements, reverse repurchase agreements, and financial derivatives are presented on a gross basis. (2) For the purpose of this presentation, for each row the total amount of financial instruments transferred or pledged and cash collateral (received) or pledged may not exceed the applicable gross amount of assets or (liabilities) as presented here. Therefore, the Company has reduced the amount of financial instruments transferred or pledged as collateral related to the Company's reverse repurchase agreements and cash collateral pledged on the Company's financial derivative liabilities. Total financial instruments transferred or pledged as collateral on the Company's reverse repurchase agreements as of June 30, 2016 and December 31, 2015 were $1.24 billion and $1.36 billion , respectively. As of June 30, 2016 and December 31, 2015, total cash collateral on financial derivative assets excludes excess net cash collateral pledged of $11.4 million and $4.1 million , respectively. As of June 30, 2016 and December 31, 2015, total cash collateral on financial derivative liabilities excludes excess cash collateral pledged of $38.6 million and $45.8 million , respectively. (3) When collateral is pledged to or pledged by a counterparty, it is often pledged or posted with respect to all positions with such counterparty, and in such cases such collateral cannot be specifically identified as relating to a specific asset or liability. As a result, in preparing the above tables, the Company has made assumptions in allocating pledged or posted collateral among the various rows.

[1]	The notional value is the maximum amount that a seller of credit protection would be obligated to pay, and a buyer of credit protection would receive upon occurrence of a "credit event." Movements in the value of credit default swap transactions may require the Company or the counterparty to post or receive collateral. Amounts due or owed under credit derivative contracts with an International Swaps and Derivatives Association, or "ISDA," counterparty may be offset against amounts due or owed on other credit derivative contracts with the same ISDA counterparty. As a result, the notional amount of written credit derivatives involving a particular underlying reference asset or index has been reduced (but not below zero) by the notional amount of any contracts where the Company has purchased credit protection on the same reference asset or index with the same ISDA counterparty.
[2]	Offsetting transactions with third parties include purchased credit derivatives which have the same reference obligation.

[1]	For the purpose of this presentation, for each row the total amount of financial instruments transferred or pledged and cash collateral (received) or pledged may not exceed the applicable gross amount of assets or (liabilities) as presented here. Therefore, the Company has reduced the amount of financial instruments transferred or pledged as collateral related to the Company's reverse repurchase agreements and cash collateral pledged on the Company's financial derivative liabilities. Total financial instruments transferred or pledged as collateral on the Company's reverse repurchase agreements as of June 30, 2016 and December 31, 2015 were $1.24 billion and $1.36 billion, respectively. As of June 30, 2016 and December 31, 2015, total cash collateral on financial derivative assets excludes excess net cash collateral pledged of $11.4 million and $4.1 million, respectively. As of June 30, 2016 and December 31, 2015, total cash collateral on financial derivative liabilities excludes excess cash collateral pledged of $38.6 million and $45.8 million, respectively.
[2]	When collateral is pledged to or pledged by a counterparty, it is often pledged or posted with respect to all positions with such counterparty, and in such cases such collateral cannot be specifically identified as relating to a specific asset or liability. As a result, in preparing the above tables, the Company has made assumptions in allocating pledged or posted collateral among the various rows.

Annual base management fee percentage			1.50%
Management fee description			The Operating Partnership pays the Manager 1.50% per annum of total equity of the Operating Partnership calculated in accordance with U.S. GAAP as of the end of each fiscal quarter (before deductions for base management fees and incentive fees payable with respect to such fiscal quarter), provided that total equity is adjusted to exclude one-time events pursuant to changes in U.S. GAAP, as well as non-cash charges after discussion between the Manager and the Company's independent directors, and approval by a majority of the Company's independent directors in the case of non-cash charges.

Incentive fee rate			25.00%
Loss Carryforward	$ 18,100		$ 18,100
Incentive fees arrangement			The Manager is entitled to receive a quarterly incentive fee equal to the positive excess, if any, of (i) the product of (A) 25% and (B) the excess of (1) Adjusted Net Income (described below) for the Incentive Calculation Period (which means such fiscal quarter and the immediately preceding three fiscal quarters) over (2) the sum of the Hurdle Amounts (described below) for the Incentive Calculation Period, over (ii) the sum of the incentive fees already paid or payable for each fiscal quarter in the Incentive Calculation Period preceding such fiscal quarter. For purposes of calculating the incentive fee, "Adjusted Net Income" for the Incentive Calculation Period means the net increase in equity from operations of the Operating Partnership, after all base management fees but before any incentive fees for such period, and excluding any non-cash equity compensation expenses for such period, as reduced by any Loss Carryforward (as described below) as of the end of the fiscal quarter preceding the Incentive Calculation Period. For purposes of calculating the incentive fee, the "Loss Carryforward" as of the end of any fiscal quarter is calculated by determining the excess, if any, of (1) the Loss Carryforward as of the end of the immediately preceding fiscal quarter over (2) the Company's net increase in equity from operations (expressed as a positive number) or net decrease in equity from operations (expressed as a negative number) of the Operating Partnership for such fiscal quarter. As of June 30, 2016 there was a Loss Carryforward of $18.1 million. For purposes of calculating the incentive fee, the "Hurdle Amount" means, with respect to any fiscal quarter, the product of (i) one-fourth of the greater of (A) 9% and (B) 3% plus the 10-year U.S. Treasury rate for such fiscal quarter, (ii) the sum of (A) the weighted average gross proceeds per share of all common share and OP Unit issuances since inception of the Company and up to the end of such fiscal quarter, with each issuance weighted by both the number of shares and OP Units issued in such issuance and the number of days that such issued shares and OP Units were outstanding during such fiscal quarter, using a first-in first-out basis of accounting (i.e. attributing any share and OP Unit repurchases to the earliest issuances first) and (B) the result obtained by dividing (I) retained earnings attributable to common shares and OP Units at the beginning of such fiscal quarter by (II) the average number of common shares and OP Units outstanding for each day during such fiscal quarter, (iii) the sum of the average number of common shares, LTIP Units, and OP Units outstanding for each day during such fiscal quarter. For purposes of determining the Hurdle Amount, issuances of common shares and OP Units (a) as equity incentive awards, (b) to the Manager as part of its base management fee or incentive fee and (c) to the Manager or any of its affiliates in privately negotiated transactions, are excluded from the calculation. The payment of the incentive fee will be in a combination of common shares and cash, provided that at least 10% of any quarterly payment will be made in common shares.

Termination Fee, Description			The Management Agreement requires the Company to pay a termination fee to the Manager in the event of (1) the Company's termination or non-renewal of the Management Agreement without cause or (2) the Company's termination of the Management Agreement based on unsatisfactory performance by the Manager that is materially detrimental to the Company (3) the Manager's termination of the Management Agreement upon a default by the Company in the performance of any material term of the Management Agreement. Such termination fee will be equal to the amount of three times the sum of (i) the average annual Quarterly Base Management Fee Amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal and (ii) the average annual Quarterly Incentive Fee Amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal.

[1]	In the Company's Consolidated Statement of Assets, Liabilities, and Equity, all balances associated with repurchase agreements, reverse repurchase agreements, and financial derivatives are presented on a gross basis.
[2]	See Note 2 and Note 3 in Notes to Consolidated Financial Statements.
[3]	See Note 2 and Note 3 in Notes to Consolidated Financial Statements.
[4]	For the purpose of this presentation, for each row the total amount of financial instruments transferred or pledged and cash collateral (received) or pledged may not exceed the applicable gross amount of assets or (liabilities) as presented here. Therefore, the Company has reduced the amount of financial instruments transferred or pledged as collateral related to the Company's reverse repurchase agreements and cash collateral pledged on the Company's financial derivative liabilities. Total financial instruments transferred or pledged as collateral on the Company's reverse repurchase agreements as of June 30, 2016 and December 31, 2015 were $1.24 billion and $1.36 billion, respectively. As of June 30, 2016 and December 31, 2015, total cash collateral on financial derivative assets excludes excess net cash collateral pledged of $11.4 million and $4.1 million, respectively. As of June 30, 2016 and December 31, 2015, total cash collateral on financial derivative liabilities excludes excess cash collateral pledged of $38.6 million and $45.8 million, respectively.
[5]	When collateral is pledged to or pledged by a counterparty, it is often pledged or posted with respect to all positions with such counterparty, and in such cases such collateral cannot be specifically identified as relating to a specific asset or liability. As a result, in preparing the above tables, the Company has made assumptions in allocating pledged or posted collateral among the various rows.
