Significant Accounting Policies [Abstract]

Significant Accounting Policies

2. 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 for investment companies, ASC 946, Financial Services—Investment Companies ("ASC 946"), for interim financial information. 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 and its wholly owned subsidiaries. All inter-company balances and transactions have been eliminated. The preparation of consolidated financial statements in conformity with generally accepted accounting principles 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.

(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, including investments in mortgage loans, or "MBS," and U.S. Treasury holdings, 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, prepayment and default rate assumptions. These assumptions are reevaluated not less than quarterly and require the use of a significant amount of judgment. Principal write-offs are generally treated as realized losses.

(D) Cash and Cash Equivalents: On the Consolidated Statement of Cash Flows the Company has revised prior period classifications to conform to current period presentation. Cash and cash equivalents include amounts held in an interest bearing overnight account and money market funds. As of September 30, 2011, all cash was held in an interest bearing account at the Bank of New York Mellon Corporation. As of December 31, 2010, 70% and 30% 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 two major types utilized are swaps and futures.

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 total return swap activity has been equity market risk. The primary risk associated with the Company's credit default swaps is credit 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 amount of a credit obligation (usually a bond or loan). 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 referenced asset. The Company is subject to market price volatility of the underlying referenced asset. A total return swap involves commitments to pay interest in exchange for a market-linked return based on a notional amount. 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 referenced securities. During the term of swap contracts, changes in value are recognized as unrealized gains or losses. When the contracts are terminated, the Company will realize 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/received by the Company to open swap contracts are recorded as an asset and/or liability on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity and are recorded as a realized gain or loss on the termination date. The Company may be required to deliver or receive cash or securities as collateral upon entering into swap transactions.

The Company's swap contracts are generally governed by ISDA trading agreements, which are separately negotiated agreements with dealer counterparties. Changes in the relative value of the swap transactions may require the Company or the counterparty to post or receive additional collateral. Typically, a collateral payment or receipt is triggered based on the net change in the value of all contracts governed by a particular ISDA trading agreement. Collateral received from counterparties is included in Due to brokers on margin accounts on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity. Collateral paid to counterparties is included in Deposits with dealers held as collateral on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity. Entering into swap contracts involves market risk in excess of amounts recorded on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity.

Futures Contracts: A futures contract is an agreement between two parties to buy and sell a financial instrument for a set price on a future date. The Company enters into Eurodollar futures contracts to hedge its interest rate risk. Initial margin deposits are made upon entering into futures contracts and can be either 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 on a daily basis to reflect the market value of the contract at the end of each day's trading. Variation margin payments are made or received periodically, depending upon whether unrealized gains or losses 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.

Derivative instruments 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, and Eurodollar futures contracts.

Swap assets are included in Financial derivatives—assets on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity. Swap liabilities are included in Financial derivatives—liabilities on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity. In addition, swap contracts are summarized by type on the Consolidated Condensed Schedule of Investments. Unrealized depreciation on futures contracts is included in Financial derivatives—liabilities on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity. For total return swaps, interest rate swaps, and credit default swaps, notional amounts reflected on the Consolidated Condensed Schedule of Investments represent approximately 1000%, 117%, and 69%, respectively, of average monthly notional amounts of each such category outstanding during the nine month period ended September 30, 2011. For interest rate swaps, credit default swaps, and futures, notional amounts reflected on the Consolidated Condensed Schedule of Investments represent approximately 318%, 133%, and 38%, respectively, of average monthly notional amounts of each such category outstanding during the year ended December 31, 2010. The Company uses average monthly notional amounts outstanding to indicate the volume of activity with respect to these instruments.

(F) Short Sales: 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 via repurchase agreement. The Company generally is required to deliver cash or securities as collateral to the repurchase agreement counterparty. A gain, limited to the price at which the Company sold the security short, or a loss, unlimited as to dollar amount, will be recognized upon the termination of a short sale if the market price is less than 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. Interest on the value of repurchase and reverse repurchase agreements issued and outstanding is based upon competitive market rates at the time of issuance. The Company accounts for reverse repurchase agreements as collateralized borrowings. 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. 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. Assets held pursuant to repurchase agreements are reflected as assets on the Consolidated Statement of Assets, Liabilities and Shareholders' 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 consolidated financial statements.

Reverse repurchase agreements are carried at their contractual amounts, which the Company believes is the best estimate of fair value. At September 30, 2011, the Company's open reverse repurchase agreements had remaining terms that ranged from 5 to 234 days and had interest rates ranging from 0.23% to 2.40%. At September 30, 2011, approximately 70% of open reverse repurchase agreements were with four counterparties. At December 31, 2010, the Company's open reverse repurchase agreements had remaining terms that ranged from 13 to 178 days and had interest rates ranging from 0.27% to 2.60%. At December 31, 2010, approximately 77% of open reverse repurchase agreements were with four counterparties.

The Company follows the provisions of ASC 860-20, Sales of Financial Assets, which requires an initial transfer of a financial asset and a repurchase financing that was entered into contemporaneously or in contemplation of the initial transfer to be evaluated as a linked transaction unless certain criteria are met, including that the transferred asset must be readily obtainable in the marketplace. As of September 30, 2011 and December 31, 2010, the Company did not have any material seller financing. No transactions are accounted for as linked transactions at September 30, 2011 and December 31, 2010.

(H) Purchased Options: The Company has entered into options primarily to help mitigate overall market risk. When the Company purchases an option, an amount equal to the premium paid is recorded as an asset 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 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. The Company had no purchased options outstanding as of September 30, 2011 and December 31, 2010.

(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 with its trading counterparties on a net basis. 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 September 30, 2011, total assets included $53.0 million of TBAs as well as $545.5 million of receivable for securities sold relating to unsettled TBA sales. As of December 31, 2010, total assets included $54.4 million of TBAs as well as $753.0 million of receivable for securities sold relating to unsettled TBA sales.

As of September 30, 2011, total liabilities included $544.8 million of TBAs sold short as well as $53.3 million of payable for securities purchased relating to unsettled TBA purchases. As of December 31, 2010, total liabilities included $749.7 million of TBAs sold short as well as $54.7 million of payable for securities purchased relating to unsettled TBA purchases. On a net basis, as of September 30, 2011, the Company held a net short position in TBAs of $491.8 million while at December 31, 2010, the Company held a net short position in TBAs of $695.3 million.

(J) Offering Costs/Placement Fees: Offering costs and placement fees are charged against shareholders' equity. Costs associated with the Company's public offering of common shares, which closed on October 14, 2010, were offset against the proceeds of the offering and charged against shareholders' equity as of December 31, 2010.

(K) LTIP Units: Long term incentive plan units ("LTIP units") have been issued to the Company's dedicated officers, independent directors as well as the Manager. Costs associated with LTIP units issued to dedicated officers 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 period for units issued to officers and independent directors under the Ellington Incentive Plan for Individuals (the "Individual LTIP") is typically one year. 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) Dividends: Dividends payable are recorded in the consolidated financial statements on the ex-dividend date.

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

(N) 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 long term incentive plan units deemed to be participating securities, by the weighted average number of common shares outstanding calculated excluding long term incentive units. Because the Company's long term incentive plan units are deemed to be participating securities and the Company has no other equity securities outstanding, basic and diluted EPS are the same. See Note 8 for EPS computations.

(O) Income Taxes: The Company intends to be treated as a partnership for U.S. federal income tax purposes. 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.

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 tax benefit to be recognized is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement which could result in the Company recording a tax liability that would reduce shareholders' equity. The Company did not have any additions to its unrecognized tax benefits resulting from tax positions related either to the current period or to 2010, 2009, 2008 or 2007 (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 since inception. The Company does not expect any change in unrecognized tax benefits within the next fiscal year.

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 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 ("FASB"), and ongoing analyses of tax laws, regulations and interpretations thereof.

(P) Subsequent Events: The Company applies the provisions of ASC 855-10, Subsequent Events, in the preparation of its consolidated financial statements. This standard establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued.

(Q) Recent Accounting Pronouncements: On May 12, 2011, the FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. generally accepted accounting principles ("U.S. GAAP") and International Financial Reporting Standards ("IFRS") ("ASU 2011-04"). This ASU represents the completion of the joint project on fair value of the FASB and International Accounting Standards Board ("IASB"). The objective of the project was to bring together as closely as possible the fair value measurement and disclosure guidance issued by the two boards. Many of the changes in the U.S. final standard represent clarifications to existing guidance. The standard also includes new required quantitative disclosures about unobservable inputs for all Level 3 fair value measurements, as well as qualitative disclosures about the sensitivity inherent in recurring Level 3 fair value measurements. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. The Company is evaluating the impact of the adoption of ASU 2011-04.

On April 29, 2011, the FASB issued ASU No. 2011-03, Transfers and Servicing—(Topic 860), Reconsideration of Effective Control for Repurchase Agreements ("ASU 2011-03"). This modifies the criteria for determining when repurchase agreements and other similar transactions would be accounted for as financings (secured borrowings/ lending agreements) as opposed to sales (purchases) with commitments to repurchase (resell). ASU 2011-03 is effective prospectively for new transfers and existing transactions that are modified in the first interim or annual period beginning on or after December 15, 2011. The Company does not expect the adoption of ASU 2011-03 to have a material impact on its consolidated financial statements.

In January 2010, the FASB issued ASU No. 2010-6 Fair Value Measurements and Disclosures—(Topic 820), Improving Disclosures about Fair Value Measurements ("ASU 2010-6"). This amends Subtopic 820-10 to require new disclosures for transfers in and out of Levels 1 and 2 and reporting gross activity in Level 3 fair value measurements, and clarifies the level of detail of existing disclosures. The new disclosures and clarifications are effective for interim and annual reporting periods beginning after December 15, 2009, with the exception of reporting certain gross activity in Level 3 fair value measurements which is effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. Adoption of ASU 2010-6 did not have a material impact on the Company's consolidated financial statements.

Valuation [Abstract]

Valuation

3. Valuation

The following is a description of the valuation methodologies used for the Company's financial instruments.

Level 1 valuation methodologies include the observation of quoted prices (unadjusted) for identical assets or liabilities in active markets, often received from widely recognized data providers.

Level 2 valuation methodologies include the observation of (i) quoted prices for similar assets or liabilities in active markets, (ii) inputs other than quoted prices that are observable for the asset or liability (for example, interest rates and yield curves) in active markets and (iii) quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3 valuation methodologies include (i) the use of proprietary models that require the use of a significant amount of judgment and the application of various assumptions including, but not limited to, prepayment and default rate assumptions, and (ii) the solicitation of valuations from third parties (typically, broker-dealers). Third-party valuation providers often utilize proprietary models that are highly subjective and also require the use of a significant amount of judgment and the application of various assumptions including, but not limited to, prepayment and default rate assumptions. The Manager utilizes such information to assign a good faith valuation (the estimated price that would be received to sell an asset or paid to transfer a liability in an orderly transaction at the valuation date) to such financial instruments. The Manager has been able to obtain third-party valuations on the vast majority of the Company's financial instruments and expects to continue to solicit third-party valuations on substantially all of the Company's financial instruments in the future to the extent practical.

The Manager uses its judgment based on its own models, the assessments of its portfolio managers, and third-party valuations it obtains, to determine and assign fair values to the Company's Level 3 financial instruments. Because of the inherent uncertainty of valuation, estimated values 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 consolidated financial statements.

There were no transfers of financial instruments between Level 1, Level 2, or Level 3 during the year ended December 31, 2010.

At December 31, 2010, the Company held money market investments that are included in cash and cash equivalents on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity and are considered Level 1 financial instruments.

In January 2010, the FASB issued ASU No. 2010-6 Fair Value Measurements and Disclosures—(Topic 820), Improving Disclosures about Fair Value Measurements, which became effective for fiscal years beginning after December 15, 2010. As a result certain classifications in the above table have been conformed to the current period presentation.

All amounts of net realized and change in net unrealized gain (loss) in the table above are reflected in the accompanying Consolidated Statement of Operations. The table above incorporates changes in net unrealized gain (loss) for both Level 3 financial instruments held by the Company at September 30, 2010, as well as Level 3 financial instruments disposed of by the Company during the three month-period ended September 30, 2010. For Level 3 financial instruments held by the Company at September 30, 2010, change in net unrealized gain (loss) of $18.9 million and $(1.6) million for the three month period ended September 30, 2010 relate to investments and financial derivative-assets, respectively.

As of September 30, 2011, the Company is party to credit derivatives contracts in the form of credit default swaps on mortgage/asset backed securities and indices, or "ABSCDS." As a seller of credit protection via ABSCDS, the Company receives periodic payments from protection buyers, and is obligated to make payments to the protection buyer upon the occurrence of a "credit event" with respect to underlying reference assets. Written credit derivatives held by the Company at September 30, 2011 and December 31, 2010, respectively, are summarized below (in thousands):


Single Name and Index Credit Default Swaps (Asset Backed Securities)	Amount at September 30, 2011			Amount at December 31, 2010
Fair Value of Written Credit Derivatives, Net	$	(15,467	)	$	(14,375	)
Fair Value of Purchased Credit Derivatives Offsetting Written Credit Derivatives with Third Parties⁽¹⁾	$	5,806		$	18,286
Notional Amount of Written Credit Derivatives⁽²⁾	$	(26,907	)	$	(111,717	)
Notional Amount of Purchased Credit Derivatives Offsetting Written Credit Derivatives with Third Parties⁽¹⁾	$	13,107		$	43,721

⁽¹⁾	Offsetting transactions with third parties include purchased credit derivatives which have the same reference obligation.

⁽²⁾

The notional amount is the maximum amount that a seller of ABSCDS 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 an ABSCDS contract may be offset against amounts due or owed on other ABSCDS contracts with the same ISDA counterparty.

Unless terminated by mutual agreement by both the buyer and seller, ABSCDS contracts typically terminate at the earlier of the (i) date the buyer of protection delivers the reference asset to the seller in exchange for payment of the notional balance following the occurrence of a credit event or (ii) date the reference asset is paid off in full, retired, or otherwise ceases to exist. Implied credit spreads may be used to determine the market value of swap contracts and are reflective of the cost of buying/selling protection. Higher spreads would indicate a greater likelihood that a seller will be obligated to perform (i.e., make payment) under the swap contract. In situations where the credit quality of an underlying reference asset has deteriorated, credit spreads combined with a percentage of notional amounts paid up front (points up front) are frequently used as an indication of ABSCDS risk. ABSCDS credit protection sellers entering the market would expect to be paid a percentage of the current notional balance up front (points up front) approximately equal to the fair value of the contract in order to write protection on the reference assets underlying the Company's ABSCDS contracts. Stated spreads at September 30, 2011 on ABSCDS contracts where the Company wrote protection range between 9 and 350 basis points on contracts that were outstanding at this date. Stated spreads at December 31, 2010 on ABSCDS contracts where the Company wrote protection range between 9 and 442 basis points on contracts that were outstanding at this date. However, participants entering the market at September 30, 2011 and December 31, 2010 would likely transact on similar contracts with material points upfront given these spreads. Total net up-front payments received relating to ABSCDS contracts outstanding at September 30, 2011 and December 31, 2010 were $13.8 million and $13.5 million, respectively.

Long-Term Incentive Plan Units [Abstract]

Long-Term Incentive Plan Units

6. Long-Term Incentive Plan Units

In connection with its initial offering in 2007, the Company established the Manager Long-Term Incentive Plan (the "Manager LTIP") and the Individual Long-Term Incentive Plan (the "Individual LTIP"). Pursuant to the terms of the Manager LTIP, the Company issued 375,000 long-term incentive plan units to its Manager. Pursuant to the terms of the Individual LTIP, each year since inception the Company has issued annual awards to its independent directors and, beginning in 2010, issued awards to certain of its officers.

As of August 17, 2010, LTIP units awarded to the Manager were fully vested and fully expensed. LTIP units held pursuant to the Manager LTIP are generally exercisable by the holder at any time after vesting. Each LTIP unit is convertible into one common share. During the three month period ended September 30, 2010, expense recognized related to the Manager LTIP was approximately $0.4 million and during the nine month period ended September 30, 2010, expense recognized related to the Manager LTIP was approximately $1.9 million. There is no cash flow effect from the issuance of the Manager LTIP units. Since inception, the aggregate expense associated with the Manager LTIP was $8.6 million.

Individual LTIP units in the amount of 3,750 units were granted to the Company's independent directors on each of August 17, 2007, December 31, 2008, October 1, 2009, October 1, 2010 and September 15, 2011. Excluding the October 1, 2010 and September 15, 2011 awards, these grants have fully vested. The vesting period for awards issued to directors under the Individual LTIP has generally been one year from the date of grant. In addition, on December 15, 2010, the Company issued a total of 2,500 LTIP units to certain of its dedicated officers. The vesting period for this grant is also one year from the date of grant. LTIP units held pursuant to the Individual LTIP are generally exercisable by the holder at any time after vesting. Each LTIP unit is convertible into one common share. Costs associated with the Individual LTIP are measured as of the grant date and expensed ratably over the vesting period. The total expenses associated with the Individual LTIP units awarded to the independent directors for the three month periods ended September 30, 2011 and 2010, were $0.03 million and $0.02 million, respectively. The total expenses associated with the Individual LTIP units awarded to the independent directors for the nine month periods ended September 30, 2011 and 2010, were $0.08 million and $0.07 million, respectively. The total expense associated with the Individual LTIP units awarded to the Company's dedicated officers for the three month period ended September 30, 2011 was approximately $0.01 million and the total expense associated with the Individual LTIP units awarded to the Company's dedicated officers for the nine month period ended September 30, 2011 was approximately $0.04 million. Unrecognized expense related to unvested Individual LTIP units awarded to independent directors was $0.06 million at September 30, 2011 and $0.07 million at December 31, 2010. Unrecognized expense related to unvested Individual LTIP units awarded to certain of the Company's dedicated officers was $0.01 millions at September 30, 2011 and $0.05 million at December 31, 2010. Since inception, 7,500 common shares were issued in connection with the conversion of Individual LTIP units awarded to independent directors at the direction of the three award holders and $0.2 million was transferred from the share-based LTIP awards to common shares in shareholders' equity.

If all of the LTIP units that have previously been issued were to be fully vested and exchanged for common shares as of September 30, 2011 and December 31, 2010, the Company's issued and outstanding common shares would increase to 16,878,631 and 16,883,342 shares, respectively, resulting in shareholders' equity per share of $22.32 and $23.91 at September 30, 2011 and December 31, 2010, respectively.

Detailed below is a roll-forward of the Company's LTIP units outstanding for the three month periods ended September 30, 2011 and 2010, respectively.

Risks [Abstract]

Risks

9. Risks

The Company may be exposed to various types of risks, including market price risk, interest rate risk, and credit risk. Market price risk is the risk of decline in value of the investments held by the Company for a number of reasons, including changes in prevailing market and interest rates, increases in defaults, increases in voluntary prepayments for investments subject to prepayment risk, and widening credit spreads. Interest rate risk is the risk associated with the effects of the fluctuations in the prevailing level of market interest rates. Credit risk includes the risk of principal loss as well as the risk that a counterparty will be unable to pay amounts in full when due. Since 2007, the U.S. residential mortgage market has experienced severe dislocations and liquidity disruptions. Over the same period mortgage loans have experienced increased rates of delinquency, foreclosure and loss, although the rate of increase has slowed. While more recently the mortgage market has improved and stabilized relative to the 2007-2009 period, home prices remain depressed and relative illiquidity in private label mortgage related assets persists.

The Company invests in credit sensitive MBS and ABS. MBS are affected by interest rates and prepayment rates, each of which are influenced by a variety of economic, geographic, social and other factors. Maturities on MBS represent stated maturity dates. Actual maturity dates may differ based on prepayment rates. The Company may invest in, or sell short, various interest rate derivative instruments and futures contracts primarily for the purpose of hedging its mortgage-backed securities portfolio against changes in value caused by changes in prevailing market interest rates. Should interest rates move unexpectedly, the Company may not achieve the anticipated benefits of the hedging instruments and may realize a loss. Further, the use of such derivative instruments involves the risk of imperfect correlation in movements in the price of the instruments, interest rates and the underlying hedged assets.

The Company transacts in various financial instruments including swaps, futures contracts and options. With these financial instruments, the Company is exposed to market risk in excess of the amounts recorded on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity.

Under current market conditions, many of the Company's portfolio securities may be considered illiquid. This may result in certain securities being disposed of at a price different from the recorded value since the market price of such securities generally is more volatile than that of more liquid securities. This may result in the Company incurring greater losses on the sale of some portfolio securities than under more stable market conditions. Such losses can adversely impact the Company's shareholders' equity. In addition, if the Company is required to liquidate all or a portion of its portfolio quickly, it may realize significantly less than the value at which it previously recorded its investments. There can be no assurance that the Company could purchase or sell a portfolio investment at the price used to calculate the Company's shareholders' equity. A decline in market value of the Company's assets may have particular material adverse consequences in instances where the Company has borrowed money based upon the market value of those assets. A decrease in market value of those assets may require the Company to post additional collateral or otherwise sell assets at a time when it may not be in the best interest of the Company to do so.

Because the Company borrows under reverse repurchase agreements based on the estimated fair value of the pledged instruments, the Company's ongoing ability to borrow under its reverse repurchase facilities may be limited and its lenders may initiate margin calls in the event of adverse changes in the market. A decrease in market value of those assets may require the Company to post additional collateral or otherwise sell assets at a time when it may not be in the best interest of the Company to do so.

The Company is party to a tri-party collateral arrangement under one of its ISDA trading agreements whereby a third party holds collateral posted by the Company. Pursuant to the terms of the arrangement the third party must follow certain pre-defined actions prior to the release of the collateral to the counterparty or to the Company. Deposits with dealers held as collateral on the Consolidated Statement of Assets, Liabilities and Shareholders' Equity includes, at September 30, 2011 and December 31, 2010, collateral posted by the Company and held by a third party custodian in the amount of $8.0 million and $9.0 million, respectively.

As of September 30, 2011, investments with an aggregate value of approximately $1.0 billion were held with dealers as collateral for various reverse repurchase agreements. The investments held as collateral include securities in the amount of $58.9 million that were sold prior to period end but for which such sale had not settled as of September 30, 2011.

The following table details the percentage of such collateral held by counterparties who hold greater than 15% of collateral for various reverse repurchase agreements as of September 30, 2011. In addition to the below, unencumbered investments, on a settlement date basis, of approximately $172.9 million were held in custody at the Bank of New York Mellon Corporation.


Dealer		% of Total Collateral on Reverse Repurchase Agreements
Deutsche Bank		19%
Morgan Stanley		17%
Bank of America		16%
Credit Suisse Group		15%

The following table details the percentage of collateral amounts held by dealers who hold greater than 15% of the Company's Deposits with dealers held as collateral account as of September 30, 2011:


Dealer		% of Total Deposits with Dealers Held as Collateral
Bank of America		37%
Citigroup		27%
JP Morgan Chase		16%

The following table details the percentage of collateral amounts held by dealers who hold greater than 15% of the Company's Due to brokers on margin accounts as of September 30, 2011:


Dealer		% of Total Due to Brokers on Margin Accounts
Morgan Stanley		43%
Credit Suisse Group		28%

The following table details the percentage of amounts held by dealers who hold greater than 15% of the Company's Receivable for securities sold as of September 30, 2011:


Dealer		% of Total Receivable for Securities Sold
Royal Bank of Scotland		25%
CS First Boston		18%

The following table details the percentage of amounts held by dealers who hold greater than 15% of the Company's Payable for securities purchased as of September 30, 2011:


Dealer		% of Total Payable for Securities Purchased
CS First Boston		55%

The Company is party to various derivative contracts generally governed by ISDA trading agreements with dealer counterparties. The Company's ISDA trading agreements, which are separately negotiated agreements with each dealer counterparty, typically contain provisions allowing, absent other considerations, a counterparty to exercise rights, to the extent not otherwise waived, against the Company in the event the Company's shareholders' equity declines over time by a predetermined percentage or falls below a predetermined floor. Such rights often include the ability to terminate (i.e., close out) open contracts at prices which may favor the counterparty, which could have a material adverse effect on the Company.

The Company's purchases and sales of TBA securities are typically governed by Master Securities Forward Transaction Agreements with dealer counterparties. These agreements are separately negotiated with each dealer counterparty and include provisions for margin maintenance, mark-to-market, and other items.

- Definition
