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"). ASC 946 requires, among other things, that investments be reported at fair value in the financial statements. The consolidated financial statements include the accounts of the Company, the Operating Partnership, and its subsidiaries. All inter-company 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. 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, 2013.

(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 transparency 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,


•	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, and


•	Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement.

A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in these securities.

(C) Securities Transactions and Investment Income: Securities transactions are generally recorded on trade date. Realized and unrealized gains and losses are calculated based on identified cost. Interest income, which includes accretion of discounts and amortization of premiums on mortgage-backed securities, or "MBS," asset-backed securities, or "ABS," commercial and residential mortgage loans, U.S. Treasury securities, sovereign debt, and securitized debt, is recognized over the life of the investment using 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 and require the use of a significant amount of judgment. Principal write-offs are generally treated as realized losses. For non-performing commercial and residential mortgage loans, purchase discounts are generally not amortized. A mortgage loan is considered non-performing if any principal and/or interest payments are more than 90 days past due.

(D) Cash and Cash Equivalents: Cash and cash equivalents include amounts held in an interest bearing overnight account and money market funds. As of March 31, 2014, 29% and 71% of cash and cash equivalents were held in the JP Morgan Prime Money Market Premier Fund and an interest bearing account at the Bank of New York Mellon Corporation, respectively. As of December 31, 2013, 27% and 73% of cash and cash equivalents were held in the JP Morgan Prime Money Market Premier Fund and an interest bearing account at the Bank of New York Mellon Corporation, respectively.

(E) Financial Derivatives: The Company enters into various types of financial derivatives. The Company's 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, or "FCM," 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. Collateral received by the Company is reflected on the Consolidated Statement of Assets, Liabilities, and Equity as "Due to Brokers." Conversely, 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 swaptions, 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 risk associated with the Company's total return swap activity is equity market risk.

The Company is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. 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 rate of interest on a notional principal amount and receives a fixed rate 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 often varies 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 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 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 Note futures contracts to hedge its interest rate risk. Initial margin deposits are made upon entering into futures contracts and can 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 or enter into swaptions. Generally, the Company enters into options primarily to help mitigate overall market, credit, or interest rate risk depending on the type of option. When the Company purchases an option, 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 that expire unexercised are recognized on the expiration date as realized losses. If an option 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 option, 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 that expire unexercised are recognized on the expiration date as realized gains. If an option 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 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 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.

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, interest rate swaps, total return swaps, futures, foreign currency forwards, and options contracts.

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. For forwards, futures, interest rate swaps, credit default swaps, total return swaps, and options, notional values reflected on the Consolidated Condensed Schedule of Investments represent approximately 132%, 129%, 96%, 94%, 83%, and 51%, respectively, of average monthly notional values of each such category outstanding during the three month period ended March 31, 2014. For options, total return swaps, interest rate swaps, futures, and credit default swaps, notional values reflected on the Consolidated Condensed Schedule of Investments represent approximately 387%, 210%, 187%, 179%, and 174%, respectively, of average monthly notional values of each such category outstanding during the year ended December 31, 2013. The Company started trading foreign currency forward contracts in December 2013; foreign currency forward contracts outstanding at December 31, 2013 represented the entire foreign currency forward activity for the year ended December 31, 2013. The Company uses average monthly notional values outstanding as an indicator of the volume of activity with respect to these instruments.

(F) Investments Sold Short: When the Company sells securities short, it typically satisfies its security delivery settlement obligation by obtaining the security sold 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 and 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 also 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 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 or 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. When the Company enters into a reverse repurchase agreement, the lender establishes and maintains an account containing cash and securities having a value not less than the repurchase price, including accrued interest, of the reverse repurchase agreement. Assets held pursuant to repurchase agreements are reflected as assets on the Consolidated Statement of Assets, Liabilities, and Equity. 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. There are no repurchase and reverse repurchase agreements netted in the Company's consolidated financial statements.

Reverse repurchase agreements are carried at their contractual amounts, which the Company believes is the best estimate of fair value. At March 31, 2014, the Company's open reverse repurchase agreements had remaining terms that averaged 59 days and ranged from 2 to 180 days, and had interest rates that averaged 0.76% and ranged from 0.30% to 2.24%. At March 31, 2014, approximately 36% of open reverse repurchase agreements were with two counterparties. At December 31, 2013, the Company's open reverse repurchase agreements had remaining terms that averaged 56 days and ranged from 2 to 180 days, and had interest rates that averaged 0.90% and ranged from 0.32% to 2.27%. At December 31, 2013, approximately 39% of open reverse repurchase agreements were with two counterparties.

(H) Securitized Debt: The Company entered into a resecuritization transaction in January 2012, which is accounted for as a collateralized borrowing. The asset contributed to the securitization was not derecognized but rather, the liability issued by the securitization was recorded to reflect the term financing of the re-securitized asset. Under ASC 820-10, the Company has elected to carry securitized debt at fair value. The asset subject to the resecuritization had a fair value of $2.3 million as of both March 31, 2014 and December 31, 2013, which is included on the respective Consolidated Condensed Schedule of Investments under Principal and Interest – Private Label Securities.

(I) 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 To Be Announced MBS ("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. As of March 31, 2014, total assets included $190.4 million of TBAs as well as $784.3 million of receivable for securities sold relating to unsettled TBA sales. As of December 31, 2013, total assets included $96.9 million of TBAs as well as $813.9 million of receivable for securities sold relating to unsettled TBA sales.

As of March 31, 2014, total liabilities included $782.7 million of TBAs sold short as well as $190.3 million of payable for securities purchased relating to unsettled TBA purchases. As of December 31, 2013, total liabilities included $812.0 million of TBAs sold short as well as $96.8 million of payable for securities purchased relating to unsettled TBA purchases. As of March 31, 2014, the Company held on an aggregate basis a short position in TBAs of $592.3 million while at December 31, 2013, the Company held in aggregate a short position in TBAs of $715.1 million.

(J) Offering Costs/Underwriters' Discount: Offering costs and underwriters' discount are charged against shareholders' equity.

(K) 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 and independent directors are amortized over the vesting period in accordance with ASC 718-10, Compensation—Stock Compensation. Costs associated with LTIP units issued to the Manager are amortized over the vesting period in accordance with ASC 505-50, Equity-Based Payments to Non-Employees. The vesting periods for units issued under the Ellington Incentive Plan for Individuals (the "Individual LTIP") to dedicated or partially dedicated personnel are typically one year and can be up to two years. The vesting periods of Individual LTIP units are typically one year for independent directors. The vesting period for units issued to the Manager under the Ellington Incentive Plan for Entities (the "Manager LTIP") occurred over a three year period that ended in August 2010. The cost of the Manager LTIP units fluctuated with the price per share until the vesting date, whereas the cost of the Individual LTIP units is based on the price per share at the initial grant date.

(L) Non-controlling interests: Non-controlling interests include the interest in the Operating Partnership owned by an affiliate of the Manager and certain related parties. Non-controlling interests also include the interest of a joint venture partner in a consolidated subsidiary. The Company adjusts the non-controlling interests owned by an affiliate of the Manager and certain related parties to align its 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 7 for further discussion of non-controlling interests.

(M) Dividends: Dividends payable by the Company are recorded in the consolidated financial statements on the ex-dividend date. Dividends are typically declared and paid on a quarterly basis in arrears.

(N) Shares Repurchased: Common shares that are repurchased by the Company subsequent to issuance decrease total number of shares outstanding and issued.

(O) 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 deemed to be participating securities, by the weighted average number of common shares outstanding calculated including LTIP units. Because the Company's LTIP units are deemed to be participating securities, they are included in the calculation of basic and diluted EPS. OP Units relating to a non-controlling interest are convertible into common shares and are included in the calculation of diluted EPS.

(P) 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.

(Q) Income Taxes: The Company intends 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. As of December 31, 2013, a subsidiary of the Company has elected to be treated as a corporation for U.S. federal income tax purposes. To date, this subsidiary has recognized a small loss.

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 its unrecognized tax benefits resulting from tax positions related either to the current period or to 2013, 2012, 2011, or 2010 (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.

To date there have been no material differences between the tax and U.S. GAAP bases of the Company's investments.

(R) Recent Accounting Pronouncements: In June 2013, the FASB issued ASU 2013-08, Financial Services-Investment Companies ("ASC 946"). This update modifies the guidance for ASC 946 for determining whether an entity is an investment company for U.S. GAAP purposes. It requires entities that adopted AICPA Statement of Position 07-1 prior to its deferral to reassess whether they continue to meet the definition of an investment company for U.S. GAAP purposes. The guidance is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2013, with retrospective application; earlier application is prohibited. Management has determined that the Company still meets the definition of an investment company under ASC 946 and, as a result, the presentation of its financial statements have not changed as a result of this ASU.

In January 2014, the FASB issued ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure ("ASU 2014-04"). This update modifies the guidance for ASC 310-40, Receivables-Troubled Debt Restructurings by Creditors. ASU 2014-04 clarifies when an in-substance repossession or foreclosure occurs that would require a transfer of a mortgage loan to real estate owned. Under ASU 2014-04, repossession or foreclosure is deemed to have occurred, and the creditor is considered to have received physical possession of residential real estate property collateralizing a mortgage loan when the creditor obtains legal title to the property upon completion of a foreclosure or the borrower conveys all interest in the property to the creditor through a deed in lieu of foreclosure or a similar legal agreement. ASU 2014-04 will become effective for annual and interim periods beginning after December 15, 2014 with early adoption permitted. ASU 2014-04 can be adopted using either a modified retrospective method or a prospective transition method with the cumulative effect being recognized in the beginning retained earnings of the earliest annual period for which ASU 2014-04 is adopted. The Company elected to adopt ASU 2014-04 effective January 1, 2014; such adoption did not have a material impact on the financial statements.
