NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands, except per share data)

(Unaudited)

1. Basis of Presentation:

The consolidated financial statements of Arlington Asset Investment Corp. (Arlington Asset) and its subsidiaries (unless the context otherwise provides, collectively, the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and with the instructions to Form 10-Q. Therefore, they do not include all information required by GAAP for complete financial statements. The interim financial statements reflect all adjustments (consisting only of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the results for the periods presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three and nine months ended September 30, 2012 are not necessarily indicative of the operating results for the entire year or any other subsequent interim period. The Company’s unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

The preparation of the Company’s financial statements in conformity with GAAP requires the Company to make estimates and assumptions affecting the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although the Company based the estimates and assumptions on historical experience, when available, market information, and on various other factors that the Company believes to be reasonable under the circumstances, management exercises significant judgment in the final determination of the estimates. Actual results may differ from these estimates.

Certain amounts in the consolidated financial statements and notes for prior periods have been reclassified to conform to the current period presentation. These reclassifications had no effect on the results of operations of the Company.

2. Financial Instruments:

  Fair Value of Financial Instruments

The accounting principles related to fair value measurements define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, not adjusted for transaction costs. Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures (ASC 820), establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3) as described below:

Level 1 Inputs— Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company;

Level 2 Inputs— Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and

Level 3 Inputs— Unobservable inputs for the asset or liability, including significant assumptions of the Company and other market participants.

The Company determines fair values for the following assets and liabilities:

Mortgage-backed securities (MBS), at fair value—

Agency-backed MBS - The Company’s agency-backed MBS, the principal and interest payments on which are guaranteed by the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac), are generally classified within Level 2 of the fair value hierarchy as they are valued after considering quoted market prices provided by a broker or dealer, or alternative pricing sources with reasonable levels of price transparency. The Company reviews broker or pricing service quotes to determine whether the quotes are relevant, for example, whether an active market exists to provide price transparency or whether the quote is an indicative price or a binding offer. The independent brokers and dealers providing market prices are those who make markets in these financial instruments.

7

Private-label MBS - The Company classifies private-label MBS within Level 3 of the fair value hierarchy because they trade infrequently and, therefore, have little or no price transparency. The Company utilizes present value techniques based on estimated cash flows of the instrument taking into consideration various assumptions derived by management and other assumptions used by other market participants. These assumptions are corroborated by evidence such as historical data, risk characteristics, transactions in similar instruments, and completed or pending transactions, when available. The significant inputs in the Company’s valuation process include default rate, loss severity, prepayment rate and discount rate. In general, significant increases (decreases) in default rate, loss severity or discount rate, in isolation, would result in a significantly lower (higher) fair value measurement.  However, significant increases (decreases) in prepayment rate may result in a significantly higher (lower) fair value measurement. It is difficult to generalize the interrelationships between these significant inputs as the actual results could differ considerably on an individual security basis.  For example, an increase in the default rate may not increase the loss severity rate if actual losses are lower than the average.  Also, changes in discount rates may be greatly influenced by market expectation at any given point based upon many variables not directly related to the MBS market.  Therefore, each significant input is closely analyzed to ascertain the reasonableness for the Company’s valuation purposes.

Establishing fair value is inherently subjective given the volatile and sometimes illiquid markets for these private-label MBS and requires management to make a number of assumptions, including assumptions about the future of interest rates, prepayment rates, discount rates, credit loss rates, and the timing of cash flows and credit losses. The assumptions the Company applies are specific to each security. Although the Company relies on the internal calculations to compute the fair value of these private-label MBS, the Company requests and considers indications of value (mark) from third-party dealers to assist in the valuation process.

Securities sold but not yet purchased, at fair value—The Company’s securities sold but not yet purchased, at fair value, represent obligations of the Company to deliver a specified MBS at a contracted price, which create a liability to purchase that MBS at prevailing prices in order to deliver the MBS in satisfaction of this obligation. The Company’s liability for the purchase of the MBS to be delivered is measured at the fair value of the MBS as of the date of the financial statements. However, these transactions expose the Company to price risk until settled, as the Company’s ultimate cost to satisfy the delivery of securities sold but not yet purchased, at fair value, may exceed the amount reflected in the consolidated balance sheet. The Company classifies MBS sold but not yet purchased, at fair value, within Level 2 of the fair value hierarchy, as they are valued after considering quoted market prices provided by a broker or dealer, or alternative pricing sources, with reasonable levels of price transparency. The Company reviews broker or pricing service quotes to determine whether the quotes are relevant, for example, whether an active market exists to provide price transparency or whether the quote is an indicative price or a binding offer. The independent brokers and dealers providing market prices are those who make markets in these financial instruments.

Other investments—The Company’s other investments consist of investments in equity securities, investment funds, interest-only MBS, and other MBS-related securities. Interest-only MBS and residual interest in a securitization of which the Company is not considered the primary beneficiary are classified within Level 3 of the fair value hierarchy.

Derivative instruments—In the normal course of the Company’s operations, the Company is a party to various financial instruments that are accounted for as derivatives in accordance with ASC 815, Derivatives and Hedging (ASC 815). The derivative instruments that trade in active markets or exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. Other derivative instruments are generally classified within Level 2 of the fair value hierarchy because they are valued using broker or dealer quotations, which are model-based calculations based on market-based inputs, including, but not limited to, contractual terms, market prices, yield curves, credit curves, measures of volatility, prepayment rates and correlations of such inputs.

Other—Cash and cash equivalents, interest receivable, deposits, other receivable, interest payable, accounts payable, accrued expenses and other liabilities are reflected in the consolidated balance sheets at their amortized cost, which approximates fair value because of the short term nature of these instruments and classified within Level 1 of the fair value hierarchy.

 —Sold securities receivable, repurchase agreements and purchase securities payable are reflected in the consolidated balance sheets at the cost basis, which approximates fair value because of the short term nature of these instruments and classified within Level 2 of the fair value hierarchy.

 —Long-term debt represents a remaining balance of trust preferred debt issued by the Company which approximates fair value due to the nature of the debenture and is classified within Level 3 of the fair value hierarchy.

Level 3 Financial Assets and Liabilities

Financial Instruments Measured at Fair Value on a Recurring Basis

As of September 30, 2012, the fair value of the Company’s Level 3, available-for-sale, private-label MBS was $196,816. These securities are primarily senior and re-REMIC tranches in securitization trusts issued between 2005 and 2010. The senior securities represent interests in securitizations that have the first right to cash flows and absorb losses last. The re-REMIC securities represent interests in re-securitizations of senior MBS and pro-rata mezzanine securities. For re-REMIC securities, the cash flows from, and any credit losses absorbed by, the underlying MBS are allocated among the re-REMIC securities issued in the re-securitization transactions based on the re-REMIC structure. For example, prime and non-prime residential senior securities have been resecuritized to create a two-tranche structure with a re-REMIC senior security and a re-REMIC subordinated security. In these re-REMIC securities, all principal payments from the underlying securities are directed to the re-REMIC senior security until the face value is fully paid off. Thereafter, all principal payments are directed to the re-REMIC subordinated security. For pro-rata mezzanine securities, principal payments from the underlying MBS are typically allocated concurrently and proportionally to the mezzanine securities along with senior securities. The re-REMIC subordinated and mezzanine securities absorb credit losses, if any, first; however, these credit losses occur only when credit losses exceed the credit protection provided to the underlying securities. Senior, re-REMIC and mezzanine securities receive interest while any face value is outstanding.

As of September 30, 2012, the Company’s senior securities and re-REMIC securities were collateralized by residential Prime and Alt-A mortgage loans and had a weighted-average original loan-to-value of 71%, weighted-average original FICO score of 729, weighted-average three-month prepayment rate of 20% and weighted-average three-month loss severities of 43%. These underlying collateral loans had a weighted-average coupon rate of 4.85%. These securities are currently rated below investment grade. The significant unobservable inputs for the valuation model include the following weighted-averages:

	September 30, 2012						December 31, 2011

Level 3 Financial Instruments Measured at Fair Value on a Non-Recurring Basis

The Company also measures certain financial assets at fair value on a non-recurring basis. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairments. Due to the nature of these financial assets, enterprise values are primarily used to value these financial assets. In determining the enterprise value, the Company analyzes various financial, performance and market factors to estimate fair value, including where applicable, market trading activity. As a result, these financial assets are classified within Level 3 of the fair value hierarchy. As of September 30, 2012, these financial assets are classified within the other investments category and represent the Company’s interest in non-public equity securities and investment funds. For the three and nine months ended September 30, 2012, the Company recorded a loss of $64 in the carrying value of these financial assets. For the nine months ended September 30, 2011, the Company recorded a loss of $85 in the carrying value of these financial assets. For the three months ended September 30, 2011, there were no changes to the carrying value of these financial assets.

(1) The Company’s MBS portfolio was primarily comprised of fixed-rate MBS at September 30, 2012 and December 31, 2011. The weighted-average coupon of the MBS portfolio at September 30, 2012 and December 31, 2011 was 4.35% and 4.85%, respectively.

(2) As of September 30, 2012 and December 31, 2011, the Company’s MBS investments with a fair value of $963,285 and $731,432, respectively, were pledged as collateral for repurchase agreements.

(3) The securities issued by Fannie Mae and Freddie Mac are not rated by any rating agency; however, they are commonly thought of as having an implied rating of “AAA.” There is no assurance, particularly given the downgrade of the U.S.’s credit rating to “AA” by Standard & Poors during the quarter ended September 30, 2011, that these securities would receive such a rating if they were ever rated by a rating agency. The weighted-average rating of the Company’s private-label senior securities is calculated based on face value of the securities.

The Company has generally purchased private-label MBS at a discount. The Company, at least on a quarterly basis, estimates the future expected cash flows based on the Company’s observation of current information and events and applying a number of assumptions related to prepayment rates, interest rates, default rates, and the timing and amount of cash flows and credit losses. These assumptions are difficult to predict as they are subject to uncertainties and contingencies related to future events that may impact the Company’s estimates and its interest income.

Interest income on the private-label MBS that were purchased at a discount to face value is recognized based on the security’s expected effective interest rate. At acquisition, the accretable yield is calculated as the difference between the undiscounted expected cash flows and the purchase price which is expected to be accreted into interest income over the remaining life of the security on a level-yield basis. The difference between the contractually required payments and the undiscounted expected cash flows represents the non-accretable difference. Based on actual payment activities and changes in estimates of undiscounted expected future cash flows, the accretable yield and the non-accretable difference can change over time. Significant increases in the amount or timing of undiscounted expected future cash flows are recognized prospectively as an adjustment to the accretable yield.

The following table presents the changes in the accretable yield on available-for-sale, private-label MBS for the three and nine months ended September 30, 2012 and 2011.

These instruments may include interest rate swaps, Eurodollar and U.S. Treasury futures contracts, put options and certain commitments to purchase and sell MBS.

During the three and nine months ended September 30, 2012, the Company entered into various financial contracts to hedge certain MBS and related borrowings and other long-term debt. These financial contracts are not designated as hedges under ASC 815.

For the three and nine months ended September 30, 2012, the Company recorded net losses of $10,972 and $27,966, respectively, on these derivatives. For the three and nine months ended September 30, 2011, the Company recorded net losses of $37,037 and $61,153, respectively, on these derivatives. The Company held the following derivative instruments as of the dates indicated:

15

	September 30, 2012					December 31, 2011
	Notional Amount		Fair Value			Notional Amount		Fair Value
No hedge designation
Eurodollar futures(1)	$	14,967,000	$	(88,855	)	$	12,157,000	$	(62,556	)

(1) The $14,967,000 total notional amount of Eurodollar futures contracts as of September 30, 2012 represents the accumulation of Eurodollar futures contracts that mature on a quarterly basis between 2012 and 2017 and have a lifetime weighted-average rate of 3.18% as compared to a lifetime weighted-average market rate of 0.80%. As of September 30, 2012, the Company maintained $95,900 as a deposit and margin against the open Eurodollar futures contracts.

(2) The $80,000 total notional amount of commitment to purchase MBS as of September 30, 2012 represents forward commitments to purchase fixed-rate MBS securities with settlement dates in the three months ending December 31, 2012.

(3) The $50,000 total notional amount of commitment to sell MBS as of September 30, 2012 represents forward commitments to sell fixed-rate MBS securities with settlement dates in the three months ending December 31, 2012.

5. Income Taxes:

The total income tax provision for the three and nine months ended September 30, 2012 was $450 and $1,271, respectively. The total income tax provision for the three and nine months ended September 30, 2011 was $259 and $1,076, respectively. The Company generated a pre-tax book income of $3,573 and $17,300 for the three and nine months ended September 30, 2012, respectively. The Company generated pre-tax book (loss) income of $(11,384) and $9,309 for the three and nine months ended September 30, 2011, respectively.

The Company’s effective tax rate for the nine months ended September 30, 2012 and 2011 was 7.35% and 11.56%, respectively. The effective tax rate during these periods was lower than the highest marginal tax rates due to the realization of deferred tax assets that were offset by a full valuation allowance. The net deferred tax assets, which are offset by a full valuation allowance, include net operating losses (NOLs), which are available to offset the current and future taxable income. The Company recorded an expected tax liability for these periods due to the expected alternative minimum taxes. Limitations prevent the Company from using its NOLs to fully offset its taxable income for alternative minimum tax purposes. The Company expects to realize additional tax benefits of NOLs in 2012, which are reflected in the Company’s projected effective tax rate for the year, along with a corresponding release of the valuation allowance previously recorded against these losses. The Company will continue to provide a valuation allowance against the other deferred tax assets to the extent the Company believes that it is more likely than not that the benefits will not be realized in the future. The Company will continue to assess the need for a valuation allowance at each reporting date.

The Company is subject to examination by the U.S. Internal Revenue Service (IRS), and other taxing authorities in jurisdictions where the Company has significant business operations, such as Virginia. An IRS examination of the Company’s tax years 2009 and 2010 is currently on-going.

6. Earnings Per Share:

Basic earnings per share includes no dilution and is computed by dividing net income or loss available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share includes the impact of dilutive securities such as stock options and unvested shares of restricted stock. The following tables present the computations of basic and diluted earnings per share for the periods indicated:

  Long-Term Incentive Plan

On April 13, 2011, the Board of Directors adopted the Arlington Asset Investment Corp. 2011 Long-Term Incentive Plan (2011 Plan). The 2011 Plan was approved by the Company’s shareholders and became effective on June 2, 2011. Under the 2011 Plan, shares of Class A common stock of the Company may be issued to employees, directors, consultants and advisors of the Company and its affiliates. As of September 30, 2012 and December 31, 2011, 488,948 and 530,519 shares, respectively, remained available for issuance under the 2011 Plan.

Performance-Based Long-Term Incentive Program

On August 13, 2012, the Compensation Committee of the Board of Directors of the Company adopted a performance-based long-term incentive program (Performance-based Program) that provides for the issuance of two types of performance share units (PSUs) from time to time pursuant to the Company’s 2011 Plan.  The Performance-based Program is designed to provide an incentive compensation opportunity that balances the Company’s internal financial objectives and external market performance.  Eligible participants in the Performance-based Program are the Company’s named executive officers.

The Compensation Committee established performance goals under the Performance-based Program. The awards under the Performance-based Program comprise of two types of PSUs: Combined Net Worth Units (Book Value PSUs) and Total Shareholder Return Units (TSR PSUs). The Book Value PSUs are eligible to vest based on the compound annualized growth in the Company’s book value per share (i.e., book value change plus dividends on a reinvested basis) during the applicable performance period.  The TSR PSUs are eligible to vest based on the Company’s compound annualized total shareholder return (i.e., share price change plus dividends on a reinvested basis) during the applicable performance period.

PSUs do not have any voting rights. No dividends are paid on outstanding PSUs during the applicable performance period.  Instead, dividend equivalents are accrued on outstanding PSUs during the applicable performance period, deemed invested in shares of Class A common stock and are paid out in shares of Class A common stock at the end of the performance period to the extent that the underlying PSUs vest. Upon settlement, vested PSUs are converted into shares of the Company’s Class A common stock on a one-for-one basis. The PSUs and dividend equivalents are settled in whole shares of Class A common stock with a cash payment in lieu of any fractional share.

The right to receive shares of Class A common stock upon vesting of PSUs at the end of the applicable performance period is subject to both continued employment and the achievement of the Company performance goals established by the Compensation Committee. The employment requirement, but not the performance requirement, is waived in the event the awardee dies, becomes disabled or retires; provided, however, that if the awardee dies, becomes disabled or retires before the first anniversary of the grant date, the number of PSUs that are earned under the performance targets are pro rated. If an awardee is terminated without “cause,” the Compensation Committee, in the exercise of its discretion, determines whether any of the PSUs have been earned, provided that the Compensation Committee may not approve a payout that exceeds the number of PSUs earned under the performance targets. In the event of a change of control, the number of PSUs that are earned for each performance period are determined immediately prior to the change of control based on actual performance and vests subject to continued employment for the remainder of the original performance period, subject to accelerated vesting in certain circumstances.

Except as described above or as the Compensation Committee at any time may otherwise determine, an awardee will forfeit the right to any PSUs if he or she terminates employment before the payment date.

The Company accounts for the Performance-based Program in accordance with ASC 718. Therefore, the Book Value PSUs are valued at the grant date market value and the estimated compensation cost is recorded over the vesting period. The Company estimates the number of shares to be issued under the Book Value PSUs on a quarterly basis based on the actual and projected results for the remaining vesting period and any adjustments required are recognized retrospectively and over the remaining vesting period.

The Total Shareholder Return PSUs are also valued at the time of grant based on valuation model and the estimated compensation cost is recorded over the vesting period using straight-line basis. The valuation of the Total Shareholder Return PSUs is performed using Monte-Carlo simulation model (Model) using various assumptions including beginning average price, expected volatility, dividend equivalents, dividend yield, and risk-free rate of return. The Model projects stock prices on a daily basis assuming 250 trading days per year. The Model generates many future stock price paths to construct a distribution of where future stock prices might be. No remeasurement of compensation expense is required for the Total Shareholder Return PSUs.

18

The compensation costs will be reversed if an employee terminates prior to completing the required service period. The estimated shares to be granted under the Performance-based Program are included in the calculation of diluted Earnings Per Share.

On August 13, 2012, the Compensation Committee of the Board of Directors of the Company approved the initial grant of 30,177 Book Value PSUs and 41,735 TSR PSUs to the participants in the Performance-based Program.

For the initial grant, the Compensation Committee awarded PSUs with an aggregate grant date fair value equal to 75% of the awardee’s base salary, with 50% of the total grant date fair value represented by Book Value PSUs and 50% of the total grant date fair value represented by TSR PSUs. To facilitate the implementation of the Performance-based Program, the Compensation Committee established both a two-year and three-year performance period for the initial grant of PSUs. A portion of the Book Value PSUs and TSR PSUs will be eligible for vesting at the end of the second year following the grant date, and a portion of the Book Value PSUs and TSR PSUs will be eligible for vesting at the end of the third year following the grant date. The Company anticipates that subsequent PSUs grants will have a three-year performance period.

The actual number of shares of Class A common stock that will be issued to each participant at the end of the applicable performance period will vary between 0% and 200% of the number of PSUs granted, depending on performance results. If the threshold level of performance goals are not achieved, no PSUs are earned. If the initial performance threshold is met, participants earn 50% of the granted PSUs for Company performance at the threshold level, 100% of the granted PSUs for Company performance at the target level and 200% of the granted PSUs for Company performance at the maximum level, with linear interpolation for achievement falling between the performance levels.

The Company recorded $96 in compensation expenses related to the Performance-based Program during the three months ended September 30, 2012.

  Share Repurchases

From time to time, the Company repurchases shares of its Class A common stock under a share repurchase program authorized by the Board of Directors in July 2010 (Repurchase Program), pursuant to which the Company is authorized to repurchase up to 500,000 shares of its Class A common stock.

Repurchases under the Repurchase Program may be made from time to time on the open market and in private transactions at management’s discretion in accordance with applicable federal securities laws. The timing of repurchases and the exact number of shares of Class A common stock to be repurchased will depend upon market conditions and other factors. The Repurchase Program is funded using the Company’s cash on hand and cash generated from operations. The Repurchase Program has no expiration date and may be suspended or terminated at any time without prior notice.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Unless the context otherwise requires or provides, references in this Quarterly Report on Form 10-Q to “we,” “us,” “our” and “our company” refer to Arlington Asset Investment Corp. (Arlington Asset) and its subsidiaries. This discussion and analysis should be read in conjunction with our financial statements and accompanying notes included in Item 1 of this Quarterly Report on Form 10-Q, as well as our audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2011.

The discussion of our consolidated financial condition and results of operations below may contain forward-looking statements. These statements, which reflect management’s beliefs and expectations, are subject to risks and uncertainties that may cause actual results to differ materially. For a discussion of the risks and uncertainties that may affect our future results, please see “Cautionary Statement About Forward-Looking Statements” immediately following Item 4 of Part I of this Quarterly Report on Form 10-Q.

Our Company

We are a principal investment firm that acquires and holds mortgage-related and other assets. We acquire residential mortgage-backed securities (MBS), either issued by U.S. government agencies or guaranteed as to principal and interest by U.S. government agencies or U.S. government-sponsored entities (agency-backed MBS). We also acquire MBS issued by private organizations (private-label MBS) subject to maintaining our exemption from regulation as an investment company under the Investment Company Act of 1940, as amended (1940 Act). We are a Virginia corporation and taxed as a C corporation for federal income tax purposes.  We operate primarily in the United States.

Factors that Affect our Results of Operations and Financial Condition

Our business is materially affected by a variety of industry and economic factors, including:

● conditions in the global financial markets and economic conditions;

● changes in interest rates and prepayment rates;

● actions taken by the U.S. Federal Reserve and the U.S. Treasury;

● changes in laws and regulations and industry practices;

● actions taken by ratings agencies with respect to the U.S.’s credit rating; and

● other market developments.

Adverse market conditions and actions by governmental authorities could adversely affect our business in many ways, including but not limited to making it more difficult for us to analyze our investment portfolio, adversely affecting our ability to maintain targeted amounts of leverage on our MBS portfolio and successfully implement our hedging strategy, and limiting our ability to follow our current investment and financing strategies. While uncertain, these potentially adverse market conditions and actions by governmental authorities may adversely affect our liquidity, financial position and results of operations. We have been and will continue to evaluate the potential impact of recent government actions, including developments relating to foreclosure suspensions and affidavit errors and various state and federal government actions affecting the market price of MBS and related derivative securities.  While it is predictably difficult to foresee the short- and long-term impact of foreclosure issues given all the uncertainties, at this time, we do not anticipate that the current foreclosure issues will have a material negative effect on our overall position and results of operations.  For further discussions on how market conditions and government actions may adversely affect our business, see “Item 1A—Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011.

Our MBS portfolio is affected by general U.S. residential real estate market conditions and the overall U.S. economic environment. In particular, our MBS strategy and the performance of our MBS portfolio is influenced by the specific characteristics of these markets, including prepayment rates, credit losses, interest rates and the interest rate yield curve. Our results of operations with respect to our MBS portfolio primarily depend on, among other things, the level of our interest income and the amount and cost of borrowings we may obtain by pledging our investment portfolio as collateral for the borrowings. Our interest income, which includes the amortization of purchase premiums and accretion of discounts, varies primarily as a result of changes in prepayment speeds of the securities in our MBS portfolio. Our borrowing cost varies based on changes in interest rates and changes in the amount we can borrow which is generally based on the fair value of the MBS portfolio and the advance rate the lenders are willing to lend against the collateral provided.

The payment of principal and interest on the agency-backed MBS that we acquire and hold is guaranteed by the Federal Home Loan Mortgage Corporation (Freddie Mac) or the Federal National Mortgage Association (Fannie Mae). The payment of principal and interest on agency-backed MBS issued by Freddie Mac or Fannie Mae is not guaranteed by the U.S. government. Any failure to honor its guarantee of agency-backed MBS by Freddie Mac or Fannie Mae or any downgrade of securities issued by Freddie Mac or Fannie Mae by the rating agencies could cause a significant decline in the value of and cash flow from any agency-backed MBS we own that are guaranteed by such entity.

Current Market Conditions and Trends

On October 4, 2012, the Federal Housing Finance Authority (FHFA) released its white paper entitled "Building a New Infrastructure for the Secondary Mortgage Market" (FHFA White Paper). This release follows upon the FHFA's February 21, 2012 Strategic Plan for Enterprise Conservatorships, which set forth three goals for the next phase of the Fannie Mae and Freddie Mac conservatorships. These three goals are to (i) build a new infrastructure for the secondary mortgage market, (ii) gradually contract Fannie Mae and Freddie Mac's presence in the marketplace while simplifying and shrinking their operations, and (iii) maintain foreclosure prevention activities and credit availability for new and refinanced mortgages.

The FHFA White Paper proposes a new infrastructure for Fannie Mae and Freddie Mac that has two basic goals. The first goal is to replace the current, outdated infrastructures of Fannie Mae and Freddie Mac with a common, more efficient infrastructure that aligns the standards and practices of the two entities, beginning with core functions performed by both entities such as issuance, master servicing, bond administration, collateral management and data integration. The second goal is to establish an operating framework for Fannie Mae and Freddie Mac that is consistent with the progress of housing finance reform and encourages and accommodates the increased participation of private capital in assuming credit risk associated with the secondary mortgage market. The FHFA recognizes that there are a number of impediments to their goals which may or may not be surmountable, such as the absence of any significant secondary mortgage market mechanisms beyond Fannie Mae, Freddie Mac and Ginnie Mae, and that their proposals are in the formative stages. As a result, it is unclear if the proposals will be enacted. If such proposals are enacted, it is unclear how closely what is enacted will resemble the proposals from the FHFA White Paper or what the effects of the enactment will be.

In September 2012, the U.S. Federal Reserve Open Market Committee announced an open-ended program (QE3) to purchase an additional $40 billion of agency-backed MBS per month until the unemployment rate, among other economic indicators, show signs of improvement. This program, when combined with the Federal Reserve's existing programs to extend its holdings' average maturity, and reinvest principal payments from its holdings of agency debt and agency-backed MBS into agency-backed MBS, is expected to increase the Federal Reserve's holdings of long-term securities by approximately $85 billion per month through the end of 2012. The Federal Reserve also announced that it will keep the target range for the Federal Funds Rate between zero and 0.25% through at least mid-2015, which is six months longer than the Federal Reserve had previously announced.

The Federal Reserve expects these measures to put downward pressure on long-term interest rates. In the short term, these actions have driven agency-backed MBS prices to new highs, which have further compressed interest spreads, and increased the sensitivity to increases in prepayments.

Our MBS portfolio continued to perform well and as expected during the quarter ended September 30, 2012.  The overall value of our agency-backed MBS portfolio increased, primarily as a result of QE3, the low interest rate environment, and the value of our private-label MBS portfolio held steady, primarily from an expected improvement in credit performance in general.  As discussed above, all together with the rest of the remainder of the Operation Twist program, it is expected that the Federal Reserve will be purchasing $85 billion in long-term securities per month for the remaining 2012 in an effort to bring down interest rates and boost the economy. Unlike the prior quantitative easing programs, QE3 is more open-ended which we consider a significant change. This has affected MBS products by increasing the price of these bonds. However, these actions by the Federal Reserve have caused some concern that the effect of lower borrowing costs will increase the prepayments of the existing MBS population. This in turn, has caused MBS with prepayment protection attributes, such as most of our MBS positions, to increase in value. However, the increase in MBS price will result in decreases in yields and net spread.

Uncertainty continues to dominate the market, due to the continued historically low interest rate environment and the European financial crisis. We believe the general business environment will continue to be challenging in the remainder of 2012 and future periods. Our growth outlook is dependent, in part, on the strength of the financial markets, the impact of fiscal and monetary policy actions by the United States and other countries, the overall market value of U.S. equities and liquidity in the financial system. Depending on the market development and movement, we may seek to re-align our strategy and our portfolio.  We will continue to closely monitor the developments in the market and evaluate the opportunities across the spectrum in the mortgage industry and seek the highest risk-adjusted returns for our capital.

Executive Summary

On September 26, 2012, we completed a public offering of 3,450,000 shares of Class A common stock, including 450,000 shares of Class A common stock purchased by the underwriters pursuant to an option granted by us to cover over-allotments, at a public offering price of $24.80 per share, for net proceeds of $83.2 million after deducting underwriting discounts and commissions and expenses. We deployed the capital raised from this public offering primarily in 30 year fixed –rate agency-backed MBS and private-label MBS. As of October 29, 2012, our agency-backed MBS portfolio consisted of $1.5 billion in face value and $1.6 billion in fair value including forward purchases and sales, a weighted average coupon of 4.1%, and expected asset yield of 2.90% assuming a 7% constant prepayment rate (CPR). The related repurchase agreement balance was $1.3 billion with a weighted average rate of 0.44%, and an average notional hedge amount of approximately $856 million extending to December 2018.

22

For the three months ended September 30, 2012, we had net income of $3.1 million, or $0.31 per share (diluted). As of September 30, 2012, our book value per share was $22.59.

In addition to the financial results reported in accordance with generally accepted accounting principles as consistently applied in the United States (GAAP), we calculated non-GAAP core operating income for the three and nine months ended September 30, 2012. Our core operating income for the three and nine months ended September 30, 2012 was $13.5 million and $33.7 million, respectively. In determining core operating income, we excluded certain costs and the following non-cash expenses: (1) compensation costs associated with stock-based awards, (2) accretion of MBS purchase discounts adjusted for principal repayments in excess of proportionate invested capital, (3) unrealized mark-to-market adjustments on the trading MBS and hedge instruments and (4) other-than-temporary impairment charges recognized. This non-GAAP measurement is used by management to analyze and assess the operating results and dividends. We believe that this non-GAAP measurement assists investors in understanding the impact of these non-core items and non-cash expenses on our performance and provides additional clarity around our forward earnings capacity and trend. A limitation of utilizing this non-GAAP measure is that the GAAP accounting effects of these events do in fact reflect the underlying financial results of our business and these effects should not be ignored in evaluating and analyzing our financial results. Therefore, we believe net income on a GAAP basis and core operating income on a non-GAAP basis should be considered together.

The following is a reconciliation of GAAP net income to non-GAAP core operating income for the three and nine months ended September 30, 2012 (dollars in thousands):

	September 30, 2012
	Three Months Ended			Nine Months Ended
GAAP net income	$	3,123		$	16,029
Adjustments
Adjusted expenses(1)		(898	)		1,425
Stock compensation		279			580
Net unrealized mark-to-market loss on trading MBS and hedge instruments		5,843			9,602
Other-than-temporary impairment charges		6,900			11,431
Adjusted interest related to purchase discount accretion(2)		(1,797	)		(5,379	)
Non-GAAP core operating income	$	13,450		$	33,688

(1) Adjusted expenses reflect certain professional fees, litigation recovery and income taxes that are not considered representative of routine or core operating-related activities of our company.

(2) Adjusted interest related to purchase discount accretion represents purchase discount accretion in excess of principal repayment in excess of proportional share of invested capital.

As of September 30, 2012, our agency-backed MBS consisted of $1.1 billion in face value with a cost basis of $1.2 billion and was fair valued at $1.2 billion. Our agency-backed MBS had a weighted-average coupon of 4.20% and a weighted-average cost of funding of 0.43% at September 30, 2012. During the three months ended September 30, 2012, we received proceeds of $189.1 million from the sale of $172.1 million in face value of our agency-backed MBS, realizing $1.5 million in net gains, or realized net gains of $7.5 million from the acquisition price. During the nine months ended September 30, 2012, we received proceeds of $301.2 million from the sale of $274.9 million in face value of our agency-backed MBS, realizing $3.8 million in gains, or realized gains of $10.2 million from the acquisition price.

We have entered into Eurodollar futures to mitigate the interest rate sensitivity which directly impacts our cost of borrowing and the market value of our agency-backed MBS. The Eurodollar futures mature through June 30, 2017 and have a lifetime weighted-average rate of 3.18%, as compared to a lifetime weighted-average market rate of 0.80% as of September 30, 2012. The value of these five-year hedge instruments is expected to fluctuate inversely relative to the agency-backed MBS portfolio and decrease in value during periods of declining interest rates and/or widening mortgage spreads. Conversely, during periods of increasing rates and/or tightening mortgage spreads, these instruments are expected to increase in value. The cost of these Eurodollar hedges will increase over their five-year term.

As of September 30, 2012, our private-label MBS portfolio consisted of $329.4 million in face value with an amortized cost basis of $159.0 million and was fair valued at $196.0 million. The unamortized net discount on our private-label MBS portfolio was $170.4 million as of September 30, 2012. During the quarter ended September 30, 2012, we recognized net interest income of $5.7 million, representing a 15.6% annualized yield, including coupon and accretion of purchase discount based on the current accretable yield rate, from our private-label MBS portfolio. We also recognized $6.9 million in other-than-temporary impairment charges during the quarter ended September 30, 2012 related to changes in expected credit performance of our available-for-sale, private-label MBS. The other-than-temporary impairment charge is a non-cash charge representing a reversal of the cumulative non-cash discount accretion previously recorded on certain of our private-label MBS. This charge does not affect non-GAAP core operating income or book value, but does reduce our net income and lowers the accounting basis used to record future discount accretion, which should more closely reflect future cash flows.

23

Our private-label MBS are primarily senior and re-REMIC tranches in securitization trusts issued between 2005 and 2010. The senior securities represent interests in securitizations that have the first right to cash flows and absorb losses last. The re-REMIC securities represents interests in re-securitizations of senior MBS and pro-rata mezzanine securities. For re-REMIC securities, the cash flows from, and any credit losses absorbed by, the underlying MBS are allocated among the re-REMIC securities issued in the re-securitization transactions based on the re-REMIC structure. For example, prime and non-prime residential senior securities have been resecuritized to create a two-tranche structure with a re-REMIC senior security and a re-REMIC subordinated security. In these re-REMIC securities, all principal payments from the underlying securities are directed to the re-REMIC senior security until the face value is fully paid off. Thereafter, all principal payments are directed to the re-REMIC subordinated security. For pro-rata mezzanine securities, principal payments from the underlying MBS are typically allocated concurrently and proportionally to the mezzanine securities along with senior securities. The re-REMIC subordinated and mezzanine securities absorb credit losses, if any, first; however, these credit losses occur only when credit losses exceed the credit protection provided to the underlying securities. Senior, re-REMIC, and mezzanine securities receive interest while any face value is outstanding. Our private-label MBS have approximately 4% credit enhancement on a weighted-average basis, which provides protection to our invested capital in addition to our purchase discount.

We generally purchased the private-label MBS in our portfolio at a discount to face value. We estimate, at least on a quarterly basis, the future expected cash flows based on our observation of current information and events and by applying a number of assumptions related to prepayment rates, interest rates, default rates, discount rates and the timing and amount of cash flows and credit losses. These assumptions, which are disclosed in note 2 to our financial statements, are difficult to predict as they are subject to uncertainties and contingencies related to future events that may impact our estimates and interest income.

We recognize interest income on our private-label MBS based on each security’s expected effective interest rate. At acquisition, the accretable yield is calculated as the difference between the undiscounted expected cash flows and the purchase price which is expected to be accreted into interest income over the remaining life of the security on a level-yield basis. The difference between the contractually required payments and the undiscounted expected cash flows represents the non-accretable difference. Based on actual payment activities and changes in estimates of undiscounted expected future cash flows, the accretable yield and the non-accretable difference can change over time. Significant increases in the amount or timing of undiscounted expected future cash flows are recognized prospectively as an adjustment to the accretable yield. As a result, we may recognize higher non-cash interest income over the security’s holding period and may not realize the level of interest income recognized using the higher accretion rates. In addition, we may be subject to more frequent and higher non-cash other-than-temporary-impairment charges than actual losses realized on the security as a result.

We evaluate available-for-sale securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. In general, when the fair value of an available-for-sale security is less than its amortized cost at the reporting date, the security is considered impaired. In evaluating these available-for-sale securities for other-than-temporary impairment, consideration is given to (1) the length of time and the extent to which the fair value has been lower than carrying value, (2) the severity of the decline in fair value, (3) the financial condition and near-term prospects of the issuer, (4) our intent to sell, and (5) whether it is more likely than not we would be required to sell the security before anticipated recovery.

For available-for-sale, agency-backed MBS securities, if it is determined that the impairment is other-than-temporary, then the amount that the fair value is below its amortized cost basis is recorded as an impairment charge and recorded through earnings. For unrealized losses that are determined to be temporary, a further evaluation is performed to determine the credit portion of the other-than-temporary impairment and the credit portion is recorded through our statement of comprehensive income.

For available-for-sale, private-label MBS securities that have been acquired at discounts to face value due in part to credit deterioration since origination, we re-evaluate the undiscounted expected future cash flows and the changes in cash flows from those originally projected at the time of purchase or last revised.  For those securities in an unrealized loss position, the difference between the carrying value and the net present value of expected future cash flows discounted using current expected rate of return is recorded as other-than-temporary impairment charges through our statement of comprehensive income. The other-than-temporary impairment charges that related to other factors other than credit are recorded in other comprehensive income, net of applicable taxes.

Continued expectations of stabilization and improvement in the housing market, increased liquidity and available leverage have stabilized prices for our private-label MBS, particularly among re-REMIC mezzanine securities. Our re-REMIC securities are predominantly held in the subordinate tranches. We will continue to closely monitor the performance of these securities. We believe we have constructed a private-label MBS portfolio with attractive characteristics and will continue to monitor relative value between the various classes of MBS, including agency-backed MBS, and may re-allocate our portfolio at any time based on management’s view of the market. We will continue to seek to identify potential opportunities to strengthen our position and to maximize return to our shareholders.

We have been evaluating, and will continue to evaluate, the opportunities across the spectrum in the mortgage industry and seek the highest risk-adjusted returns for our capital. We evaluate and prioritize the risk-adjusted return we expect to receive on every asset based upon a current cash yield perspective as well as from a total yield perspective that includes expected reflation, which is defined as an increase in value between the amortized cost basis and the par value of the security. Historically, based on market conditions, we believe our MBS assets have provided us with higher relative risk-adjusted rates of return than most other portfolio opportunities we have evaluated. Consequently, we have maintained a high allocation of our assets and capital in this sector. We intend to continue to evaluate acquisition opportunities against the returns available in each of our asset alternatives and endeavor to allocate our assets and capital with an emphasis toward what we believe will generate the highest risk-adjusted return available. This strategy may cause us to have different allocations of capital in different environments. We believe we have constructed a private-label MBS portfolio with attractive characteristics and will continue to monitor relative value between the various classes of MBS.

Results of Operations

Three months ended September 30, 2012 compared to three months ended September 30, 2011

We reported net income of $3.1 million for the three months ended September 30, 2012 compared to a net loss of $11.6 million for the three months ended September 30, 2011 which included the following results for the periods indicated (dollars in thousands):

	Three Months Ended September 30,

Net income (loss)	$	3,123		$	(11,643	)

Net income increased $14.7 million from a loss of $11.6 million for the three months ended September 30, 2011 to net income of $3.1 million for the three months ended September 30, 2012 due to the following changes:

● Net interest income increased $1.9 million (15.3%) from $12.4 million for the three months ended September 30, 2011 to $14.3 million for the three months ended September 30, 2012. The increase is the result of the increase in our investable capital on a leveraged basis to our MBS portfolio, primarily from the deployment of capital raised from our public offering of 2,018,250 shares of Class A common stock, including 263,250 shares of Class A common stock granted to the underwriters to cover the over-allotments, during the three months ended March 31, 2012, the net proceeds of which were $40.2 million after deducting underwriters’ discounts and commissions and expenses..

● Investment loss, net, decreased $14.5 million (71.8%) from a loss of $20.2 million for the three months ended September 30, 2011 to a loss of $5.7 million for the three months ended September 30, 2012. See below for additional discussion on the results of our principal investing portfolio.

The change in the composition of our MBS portfolio and related increase in net interest income by $1.9 million from the three months ended September 30, 2011 to the three months ended September 30, 2012 was primarily due to the deployment of capital raised from our public offerings during the three months ended September 30, 2012 and March 31, 2012 primarily into our agency-backed MBS portfolio. Interest income from other investments represents interest on interest-only MBS securities.

As discussed above, we realized net investment loss of $5.7 million for the three months ended September 30, 2012 compared to a net investment loss of $20.2 million for the three months ended September 30, 2011. The following table summarizes the components of net investment loss (dollars in thousands):

	Three Months Ended September 30,
	2012			2011
Realized gains on sale of available-for-sale investments, net	$	49		$	987
Available-for-sale and cost method securities – other-than-temporary impairment charges		(6,900	)		—
Gains on trading investments, net		10,627			15,855
Losses from derivative instruments, net		(10,972	)		(37,037	)
Other, net		1,533			—
Investment loss, net	$	(5,663	)	$	(20,195	)

We recorded other-than-temporary impairment charges of $6.9 million for the three months ended September 30, 2012 related to changes in expected credit performance on available-for-sale, private-label MBS with a cost basis of $24.0 million. We recorded no other-than-temporary impairment charges on MBS during the three months ended September 30, 2011.

During the three months ended September 30, 2012, the Company received $1.0 million from the sales of $4.9 million in face value of available-for-sale MBS recognizing a net gain of $49.2 thousand. During the three months ended September 30, 2011, the Company received $5.9 million from the sales of $7.5 million in face value of available-for-sale MBS recognizing a net gain of $1.0 million.

The gains on trading investments, net, recognized for the three months ended September 30, 2012 were primarily the result of net mark-to-market gain adjustments of $9.1 million and net gains of $1.5 million from sales of trading investments.  The gains on trading investments, net, recognized for the three months ended September 30, 2012, also reflects net realized gains of $7.5 million on the sold securities from the acquisition price and changes in net unrealized mark-to-market gain adjustments of $3.1 million during the three months ended September 30, 2012. The gain on trading investments, net, recognized for the three months ended September 30, 2011 was the result of net mark-to-market gain adjustments of $15.9 million.

Losses from derivative instruments recognized for the three months ended September 30, 2012 were the result of net realized losses of $0.1 million and net unrealized mark-to-market loss adjustments of $10.9 million. Losses from derivative instruments recognized for the three months ended September 30, 2012 also reflects net losses of $2.0 million from disposed derivative instruments from the acquisition price and changes in net unrealized mark-to-market loss adjustments of $9.0 million during the three months ended September 30, 2012. Losses from derivative instruments recognized for the three months ended September 30, 2011 were primarily the result of net realized losses of $0.5 million and unrealized mark-to-market loss adjustments of $36.5 million. The value of our hedge instruments is expected to fluctuate inversely relative to the change in value of the agency-backed MBS portfolio. The mark-to-market loss adjustments reflect the impact of declining interest rates and/or widening mortgage spreads during 2011 and 2012.

Other, net primarily reflects proceeds received from the assignment of a claim that related to an agency MBS under a repurchase agreement maintained with Lehman Brothers Inc. during its bankruptcy proceedings.

Interest expense unrelated to our principal investing activity relates to long-term debt. These costs increased to $122.9 thousand for the three months ended September 30, 2012 from $115.1 thousand for the three months ended September 30, 2011.

Other expenses increased by $1.4 million (38.9%) from $3.6 million for the three months ended September 30, 2011 to $5.0 million for the three months ended September 30, 2012. The increase is primarily the result of increases in legal expenses and variable compensation.

Total income tax provision increased $0.2 million (66.7%) from a provision of $0.3 million for the three months ended September 30, 2011 to $0.5 million for the three months ended September 30, 2012. Our effective tax rate was 12.59% for the three months ended September 30, 2012 as compared to (2.28)% for the same period in 2011. During the three months ended September 30, 2012, ordinary taxable income was subject to alternative minimum tax. Our effective tax rates during these periods differed from statutory rates primarily due to the expected use of federal and state net operating losses (NOLs) to offset our taxable income earned during those periods. Our NOLs had been recorded as deferred tax assets subject to a valuation allowance. We recorded an expected tax liability for these periods due to taxable income for the three months ended September 30, 2012 and 2011 that is anticipated to be subject to the alternative minimum tax. Limitations prevent us from using our NOLs to fully offset our taxable income for alternative minimum tax purposes.Further, the discrete period reporting of accrued interest and penalties on unrecognized tax positions as of September 30, 2012 remains a major contributor of the total tax expense.

Nine months ended September 30, 2012 compared to nine months ended September 30, 2011

We reported net income of $16.0 million for the nine months ended September 30, 2012 compared to net income of $8.2 million for the nine months ended September 30, 2011 which included the following results for the periods indicated (dollars in thousands):

Net income increased $7.8 million (95.1%) from $8.2 million for the nine months ended September 30, 2011 to $16.0 million for the nine months ended September 30, 2012 due to the following changes:

● Net interest income increased $4.6 million (12.4%) from $37.1 million for the nine months ended September 30, 2011 to $41.7 million for the nine months ended September 30, 2012. The increase is the result of the increase in our investable capital on a leveraged basis to our MBS portfolio, primarily from the deployment of capital raised from our public offering during the three months ended March 31, 2012.

● Investment loss, net, decreased $6.0 million from net investment loss of $17.5 million for the nine months ended September 30, 2011 to a net investment loss of $11.5 million for the nine months ended September 30, 2012.

The change in the composition of our MBS portfolio and related increase in net interest income by $4.6 million from the nine months ended September 30, 2011 to the nine months ended September 30, 2012 was primarily due to the deployment of capital raised from our public offerings during the three months ended September 30, 2012 and March 31, 2012 primarily into our agency-backed MBS portfolio. Interest income from other investments represents interest on interest-only MBS securities.

As discussed above, we realized a net investment loss of $11.5 million for the nine months ended September 30, 2012 compared to a net investment loss of $17.5 million for the nine months ended September 30, 2011. The following table summarizes the components of net investment loss (dollars in thousands):

Losses from derivative instruments recognized for the nine months ended September 30, 2011 were primarily the result of net realized losses of $1.9 million and net unrealized mark-to-market loss adjustments of $59.2 million. The value of our hedge instruments is expected to fluctuate inversely relative to the change in value of the agency-backed MBS portfolio. The mark-to-market loss adjustments reflect the impact of declining interest rates and/or widening mortgage spreads during 2011 and 2012.

Other, net primarily reflects proceeds received from the assignment of a claim that related to an agency MBS under a repurchase agreement maintained with Lehman Brothers Inc. during its bankruptcy proceedings.

Interest expense unrelated to our principal investing activity relates to long-term debt. These costs increased to $371.4 thousand for the nine months ended September 30, 2012 from $344.5 thousand for the nine months ended September 30, 2011.

Other expenses increased by $2.5 million (24.0%) from $10.4 million for the nine months ended September 30, 2011 to $12.9 million for the nine months ended September 30, 2012, primarily as a result of increases in legal expenses.

Our effective tax rate was 7.35% for the nine months ended September 30, 2012 as compared to 11.56% for the same period in 2011. During the nine months ended September 30, 2012, ordinary taxable income was subject to alternative minimum tax. Our effective tax rates during these periods differed from statutory rates primarily due to the expected use of federal and state NOLs to offset our taxable income earned during those periods. Our NOLs had been recorded as deferred tax assets subject to a valuation allowance. We recorded an expected tax liability for these periods due to taxable income for the three months ended September 30, 2012 and 2011 that is anticipated to be subject to the alternative minimum tax. Limitations prevent us from using our NOLs to fully offset our taxable income for alternative minimum tax purposes.Further, the discrete period reporting of accrued interest and penalties on unrecognized tax positions as of September 30, 2012 remains a major contributor of the total tax expense.

Liquidity and Capital Resources

Liquidity is a measurement of our ability to meet potential cash requirements including ongoing commitments to repay borrowings, fund investments, and for other general business purposes. Our primary sources of funds for liquidity consist of short-term borrowings (e.g., repurchase agreements), principal and interest payments on MBS and proceeds from sales of MBS. Other sources of liquidity include proceeds from the offering of common stock, preferred stock, debt securities or other securities registered pursuant to our effective shelf registration statement filed with the SEC. Pursuant to our shelf registration statement, on September 26, 2012, we completed a public offering of 3,450,000 shares of Class A common stock, including 450,000 shares purchased by the underwriters pursuant to an option granted by us to cover over-allotments, at a public offering price of $24.80 per share, for net proceeds of $83.2 million, after deducting underwriting discounts and commissions and expenses.

Pursuant to our shelf registration statement, on March 26, 2012, we completed a public offering of 1,755,000 shares of Class A common stock, at a public offering price of $23.90 per share, for net proceeds of $40.2 million, after deducting underwriting discounts and commissions and expenses.  In addition, on April 18, 2012, we completed the issuance and sale of 263,250 additional shares of Class A common stock pursuant to the full exercise of the underwriters’ over-allotment option, at a public offering price of $23.90 per share less the $0.875 per share dividend declared on March 16, 2012 pursuant to the Underwriting Agreement dated March 22, 2012, for net proceeds of $5.9 million, net of underwriting discounts and commissions and expenses.

Liquidity, or ready access to funds, is essential to our business. Liquidity is of particular importance to our business and perceived liquidity issues may affect our counterparties’ willingness to engage in transactions with us. Our liquidity could be impaired due to circumstances that we may be unable to control, such as a general market disruption or an operational problem that affects us or third parties. Further, our ability to sell assets may be impaired if other market participants are seeking to sell similar assets at the same time. If we cannot obtain funding from third parties or from our subsidiaries, our results of operations could be negatively impacted.

Potential future sources of liquidity for us include existing cash balances, borrowing capacity through margin accounts and repurchase agreements and cash flows from operations, future issuances of common stock, preferred stock, debt securities or other securities registered pursuant to our shelf registration statement. Funding for agency-backed MBS through repurchase agreements continues to be available to us at rates we consider to be attractive from multiple counterparties, and we have observed increased availability for funding for private-label MBS through repurchase agreements. Although the availability of the third-party sources of liquidity has improved, we have observed that market conditions are still constraining access to debt capital relative to pre-crisis levels of 2007. As a result, the availability of certain short-term liquidity such as commercial paper borrowings was still limited as of September 30, 2012.

  Cash Flows

As of September 30, 2012, our cash and cash equivalents totaled $85.7 million, representing a net increase in the balance of $65.7 million from $20.0 million as of December 31, 2011. The cash provided by operating activities of $18.2 million was attributable primarily to net income. The cash used in investing activities of $277.3 million relates primarily to purchases of MBS, net of proceeds from the sales of MBS. The cash provided by financing activities of $324.8 million relates primarily to proceeds from repurchase agreements used to finance a portion of the MBS portfolio and the completed public offerings of Class A common stock.

  Sources of Funding

We believe that our existing cash balances, investments in private-label MBS, net investments in agency-backed MBS, cash flows from operations, borrowing capacity and other sources of liquidity will be sufficient to meet our cash requirements for at least the next 12 months. We have obtained, and believe we will be able to continue to obtain, short-term financing in amounts and at interest rates consistent with our financing objectives. We may, however, seek debt or equity financings, in public or private transactions, to provide capital for corporate purposes and/or strategic business opportunities, including possible acquisitions, joint ventures, alliances or other business arrangements which could require substantial capital outlays. Our policy is to evaluate strategic business opportunities, including acquisitions and divestitures, as they arise. There can be no assurance that we will be able to generate sufficient funds from future operations, or raise sufficient debt or equity on acceptable terms, to take advantage of investment opportunities that become available. Should our needs ever exceed these sources of liquidity, we believe that most of our investments could be sold, in most circumstances, to provide cash. However, we may be required to sell our assets in such instances at depressed prices.

As of September 30, 2012, our liabilities totaled $1.3 billion. In addition to other payables and accrued expenses, our indebtedness consisted of repurchase agreements and long-term debentures. These long-term debentures accrue and require payments of interest quarterly at annual rates of three-month LIBOR plus 2.25% to 3.00%, mature between 2033 and 2035 and are currently redeemable by us, in whole or in part, without penalty. As of September 30, 2012, we had $15.0 million of total long-term debt.  As of September 30, 2012, our debt-to-equity leverage ratio was 2.9 to 1.

We also have short-term financing facilities that are structured as repurchase agreements with various financial institutions to primarily fund our portfolio of agency-backed MBS. As of September 30, 2012, the weighted-average interest rate under these agreements was 0.49%. Our repurchase agreements include provisions contained in the standard master repurchase agreement as published by the Securities Industry and Financial Markets Association and may be amended and supplemented in accordance with industry standards for repurchase facilities. Our repurchase agreements include financial covenants, with which the failure to comply would constitute an event of default under the applicable repurchase agreement. Similarly, each repurchase agreement includes events of insolvency and events of default on other indebtedness. As provided in the standard master repurchase agreement as typically amended, upon the occurrence of an event of default or termination event the applicable counterparty has the option to terminate all repurchase transactions under such counterparty’s repurchase agreement and to demand immediate payment of any amount due from us to the counterparty.

Under our repurchase agreements, we may be required to pledge additional assets to our repurchase agreement counterparties in the event the estimated fair value of the existing pledged collateral under such agreements declines and such lenders demand additional collateral (i.e., a margin call), which may take the form of additional securities or cash. Margin calls on repurchase agreements collateralized by our MBS investments primarily result from events such as declines in the value of the underlying mortgage collateral caused by factors such as rising interest rates or prepayments.

To date, we have not had any margin calls on our repurchase agreements that we were not able to satisfy with either cash or additional pledged collateral. However, should we encounter increases in interest rates or prepayments, margin calls on our repurchase agreements could result in a material adverse change in our liquidity position.

In the event that market conditions are such that we are unable to obtain financing for our investments in MBS in amounts and at interest rates consistent with our financing objectives, to the extent deemed appropriate, we may use cash to finance our investments or we may liquidate such investments. Accordingly, depending on market conditions, we may incur significant losses on any such sales of MBS.

Weighted-average term to maturity	11.8 days			13.1 days
Maximum amount outstanding at any month-end during the period	$	974,901		$	659,459

  Assets

Our principal assets consist of MBS, cash and cash equivalents, receivables, deposits and long-term investments. As of September 30, 2012, liquid assets consisted primarily of cash and cash equivalents of $85.7 million and net investments in MBS of $527.7 million. Cash equivalents consist primarily of money market funds invested in debt obligations of the U.S. government. Our total assets increased from $1.0 billion at December 31, 2011 to $1.6 billion as of September 30, 2012. The increase in total assets reflects the deployment of capital raised from our public offerings during the three months ended September 30, 2012 and March 31, 2012 primarily into our agency-backed MBS portfolio on a leveraged basis.

As of September 30, 2012, the total par and fair value of the MBS portfolio was $1.4 billion. As of September 30, 2012, the weighted-average coupon of the portfolio was 4.35%.

  Dividends

Pursuant to our variable dividend policy, our Board of Directors evaluates dividends on a quarterly basis and, in its sole discretion, approves the payment of dividends. Our dividend payments, if any, may vary significantly from quarter to quarter. The Board of Directors has approved and we have declared the following dividends to date in 2012:

March 31		0.750	March 24	April 4	April 29

Off-Balance Sheet Arrangements

As of September 30, 2012 and December 31, 2011, we did not maintain any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance, special purpose or variable interest entities, established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Further, as of September 30, 2012 and December 31, 2011, we had not guaranteed any obligations of unconsolidated entities or entered into any commitment or had any intent to provide funding to any such entities.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk generally represents the risk of loss through a change in realizable value that can result from a change in the prices of securities, a change in the value of financial instruments as a result of changes in interest rates, a change in the volatility of interest rates or a change in the credit rating of an issuer. We monitor market and business risk, including credit, interest rate, equity, operations, liquidity, compliance, legal, reputational, and equity ownership risks through a number of control procedures designed to identify and evaluate the various risks to which our business and assets are exposed.  See “Item 1—Business” in our Annual Report on Form 10-K for the year ended December 31, 2011 for a discussion of our risk management strategies.

We are exposed to the following market risks as a result of our investments in MBS and equity investments.

Credit Risk

Although we do not expect to encounter credit risk in our agency-backed MBS portfolio assuming Fannie Mae and Freddie Mac remain solvent, we are exposed to credit risk in our private-label MBS portfolio. With respect to our private-label MBS, credit support contained in these MBS deal structures provides a level of protection from losses, as do the discounted purchase prices in the event of the return of less than 100% of par. We also evaluate the impact of credit risk on our investments through a comprehensive investment review and selection process, which is predominantly focused on quantifying and pricing credit risk. We review our private-label MBS based on quantitative and qualitative analysis of the risk-adjusted returns on such investments. Through modeling and scenario analysis, we seek to evaluate each investment’s credit risk. Credit risk is also monitored through our ongoing asset surveillance. Despite these measures to manage credit risk, unanticipated credit losses could nevertheless occur, which could adversely impact our operating results.

Our private-label MBS are generally purchased at a discount. We estimate the future expected cash flows based on our observation of current information and events and applying a number of assumptions related to prepayment rates, interest rates, default rates, and the timing and amount of credit losses. These assumptions are difficult to predict as they are subject to uncertainties and contingencies related to future events that may impact our estimates and interest income.

The following table represents certain statistics of our private-label MBS portfolio as of and for the three months ended September 30, 2012:

	Senior Securities			Re-REMIC Securities			Total Private- Label Securities
Yield (% of amortized cost)		17.1	%		16.0	%		16.1	%
Average cost (% of face value)		61.7	%		47.2	%		47.8	%
Weighted-average coupon		2.9	%		4.9	%		4.9	%
Delinquencies greater than 60 plus days		35.6	%		18.2	%		18.8	%
Credit enhancement		0.6	%		4.2	%		4.1	%
Severity (three months average)		47.3	%		42.9	%		43.0	%
Constant prepayment rate (three months average)		16.2	%		19.9	%		19.7	%

Key credit and prepayment measures in our private-label MBS portfolio reflected improvement during the three months ended September 30, 2012. Total 60-day plus delinquencies in our private-label MBS portfolio decreased to 18.8% at September 30, 2012 from 19.4% at June 30, 2012 and trailing three month average loss severities on liquidated loans decreased to 46.0% at September 30, 2012 from 48.8% at June 30, 2012. We will continue to monitor the performance of each security in our portfolio and assess the impact on the overall performance of the portfolio.

The table that follows shows the expected change in fair value for our current private-label MBS related to our principal investing activities under several hypothetical credit loss scenarios. Our private-label MBS are classified as Level 3 assets of the fair value hierarchy as they are valued using present value techniques based on estimated cash flows of the security taking into consideration various assumptions derived by management and used by other market participants. These assumptions include, among others, interest rates, prepayment rates, discount rates, credit loss rates, and the timing of cash flows and credit losses. Credit default and loss severity rates can significantly affect the prices of private-label MBS. While it is impossible to project exact amount of changes in value, the table below illustrates the impact a 10% increase and a 10% decrease in the credit default and loss severity rates from those used as our valuation assumptions would have on the value of our total assets and our book value as of September 30, 2012. The changes in rates are assumed to occur instantaneously. Actual changes in market conditions are likely to be different from these assumptions (dollars in thousands, except per share amounts).

Interest Rate Risk

  Leveraged MBS

We are also subject to interest rate risk in our MBS portfolio. Some of our MBS positions are financed with repurchase agreements, which are interest rate sensitive financial instruments. We are exposed to interest rate risk that fluctuates based on changes in the level or volatility of interest rates and mortgage prepayments and in the shape and slope of the yield curve. We attempt to hedge a portion of our exposure to interest rate fluctuations through the use of Eurodollar futures and U.S. Treasury note futures. The counterparties to our derivative agreements at September 30, 2012 are U.S. financial institutions. We assess and monitor the counterparties’ non-performance risk and credit risk on a regular basis.

Our primary risk is related to changes in both short- and long-term interest rates, which affect us in several ways. As interest rates increase, the market value of the MBS may be expected to decline, prepayment rates may be expected to go down, and duration may be expected to extend. An increase in interest rates is beneficial to the market value of our derivative instruments. For example, for interest rate swap positions, the cash flows from receiving the floating rate portion increase and the fixed-rate paid remains the same under this scenario. If interest rates decline, the reverse is true for MBS, paying fixed and receiving floating interest rate swaps, interest rate caps, and Eurodollar and U.S. Treasury futures and MBS put option contracts.

The table that follows shows the expected change in fair value for our current MBS and derivatives related to our principal investing activities under several hypothetical interest-rate scenarios. Interest rates are defined by the U.S. Treasury yield curve. The changes in rates are assumed to occur instantaneously. It is further assumed that the changes in rates occur uniformly across the yield curve and that the level of LIBOR changes by the same amount as the yield curve. Actual changes in market conditions are likely to be different from these assumptions.

Changes in value are measured as percentage changes from their respective values presented in the column labeled “Value.” Management’s estimate of change in value for MBS is based on the same assumptions it uses to manage the impact of interest rates on the portfolio. Actual results could differ significantly from these estimates. For MBS, the estimated change in value of the MBS reflects an effective duration of 4.43 in a rising interest rate environment and 2.40 in a declining interest rate environment.

The effective durations are based on observed market value changes, as well as management’s own estimate of the effect of interest rate changes on the fair value of the investments including assumptions regarding prepayments based, in part, on age of and interest rate on the mortgages underlying the MBS, prior exposure to refinancing opportunities, and an overall analysis of historical prepayment patterns under a variety of past interest rate conditions (dollars in thousands, except per share amounts).

Equity Price Risk

Although limited, we are exposed to equity price risk as a result of our investments in equity securities and investment partnerships. Equity price risk changes as the volatility of equity prices changes or the values of corresponding equity indices change.

While it is impossible to exactly project what factors may affect the prices of equity sectors and how much the effect might be, the table below illustrates the impact a 10% increase and a 10% decrease in the price of the equities held by us would have on the value of our total assets and our book value as of September 30, 2012 (dollars in thousands, except per share amounts).

	September 30, 2012
	Value		Value with 10% Increase in Price		Percent Change			Value with 10% Decrease in Price		Percent Change
Assets
Equity and cost method investments	$	1,933	$	2,126		10.00	%	$	1,740		(10.00	)%
Other		1,593,853		1,593,853		—			1,593,853		—
Total assets	$	1,595,786	$	1,595,979		0.01	%	$	1,595,593		(0.01	)%
Liabilities	$	1,296,668	$	1,296,668		—		$	1,296,668		—
Equity		299,118		299,311		0.06	%		298,925		(0.06	)%
Total liabilities and equity	$	1,595,786	$	1,595,979		0.01	%	$	1,595,593		(0.01	)%
Book value per share	$	22.59	$	22.61		0.06	%	$	22.58		(0.06	)%

Except to the extent that we sell our equity securities or other investments, or a decrease in their fair value is deemed to be other-than-temporary, an increase or decrease in the fair value of those assets will not directly affect our earnings; however, an increase or decrease in the value of equity method investments will directly affect our earnings.

Inflation Risk

Virtually all of our assets and liabilities are interest rate sensitive in nature. As a result, interest rates and other factors influence our performance far more than inflation.  Changes in interest rates do not necessarily correlate with inflation rates or changes in inflation rates.  Our financial statements are prepared in accordance with GAAP and our distributions are determined by our Board of Directors in its sole discretion pursuant to our variable dividend policy; in each case, our activities and balance sheet are measured with reference to fair value without considering inflation.

Item 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, our management, with the participation of our Chief Executive Officer, Eric F. Billings, and our Chief Financial Officer, Kurt R. Harrington, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined under Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)) pursuant to Rule 13a-15(b) of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding disclosure.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting during the quarter ended September 30, 2012 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Cautionary Statement About Forward-Looking Statements

When used in this Quarterly Report on Form 10-Q, in future filings with the SEC or in press releases or other written or oral communications, statements which are not historical in nature, including those containing words such as “believe,” “expect,” “anticipate,” “estimate,” “plan,” “continue,” “intend,” “should,” “may” or similar expressions, are intended to identify “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the Securities Act), and Section 21E of the Exchange Act and, as such, may involve known and unknown risks, uncertainties and assumptions. The forward-looking statements we make in this Quarterly Report on Form 10-Q include, but are not limited to, statements about the following:

● the availability and terms of, and our ability to deploy, capital and our ability to grow our business through a strategy focused on acquiring primarily residential mortgage-backed securities (MBS) that are either issued by U.S. government agencies or guaranteed as to principal and interest by U.S. government agencies or U.S. government sponsored agencies (agency-backed MBS), and MBS issued by private organizations (private-label MBS);

● our ability to forecast our tax attributes, which are based upon various facts and assumptions, and our ability to protect and use our net operating losses (NOLs), and net capital losses (NCLs), to offset future taxable income and gains;

● our investment, hedging and financing strategies and the success of these strategies;

● the effect of changes in prepayment rates, interest rates and default rates on our portfolio;

Forward-looking statements are based on our beliefs, assumptions and expectations of our future performance, taking into account information currently in our possession.  These beliefs, assumptions and expectations may change as a result of many possible events or factors, not all of which are known to us or are within our control.  If a change occurs, the performance of our portfolio and our business, financial condition, liquidity and results of operations may vary materially from those expressed, anticipated or contemplated in our forward-looking statements.  You should carefully consider these risks, along with the following factors that could cause actual results to vary from our forward-looking statements, before making an investment in our securities:

● effects of regulatory proceedings, litigation and contractual claims against us, our officers and our directors;

● the overall environment for interest rates, changes in interest rates, interest rate spreads, the yield curve and prepayment rates;

● current conditions and further adverse developments in the residential mortgage market and the overall economy;

● potential risk attributable to our mortgage-related portfolios, including changes in fair value;

37

● our use of leverage and our dependence on repurchase agreements and other short-term borrowings to finance our mortgage-related holdings;

● the availability of certain short-term liquidity sources;

● the federal conservatorship of the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac) and related efforts, along with any changes in laws and regulations affecting the relationship between Fannie Mae and Freddie Mac and the federal government;

● mortgage loan prepayment activity, modification programs and future legislative action;

● changes in our acquisition, hedging and leverage strategies, changes in our asset allocation and changes in our operational policies, all of which may be changed by us without shareholder approval;

● competition for investment opportunities, including competition from the U.S. Department of Treasury (U.S. Treasury) and the Federal Reserve, for investments in agency-backed MBS;

● failure of sovereign or municipal entities to meet their debt obligations or a downgrade in the credit rating of such debt obligations;

● fluctuating quarterly operating results;

● changes in laws and regulations and industry practices that may adversely affect our business; and

● volatility of the securities markets and activity in the secondary securities markets.

These and other risks, uncertainties and factors, including those described elsewhere in this Quarterly Report on Form 10-Q, could cause our actual results to differ materially from those projected in any forward-looking statements we make. All forward-looking statements speak only as of the date on which they are made. New risks and uncertainties arise over time and it is not possible to predict those events or how they may affect us. Except as required by law, we are not obligated to, and do not intend to, update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

The disclosure below updates and supplements the information set forth under “Item 3—Legal Proceedings” in our Annual Report on Form 10-K for the year ended December 31, 2011 and under “Part II—Other Information.  Item I—Legal Proceedings” in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2012.

As previously disclosed, we received a “Wells Notice” from the staff of the SEC on January 26, 2012 indicating that the staff is considering recommending that the SEC bring a civil injunctive action or institute a public administrative proceeding alleging violations of the federal securities laws. On February 29, 2012, we provided a written submission setting forth reasons why a formal proceeding should not be authorized by the SEC. On June 4, 2012, our counsel met with members of the SEC staff to discuss the Notice and our responsive submission, and, on August 16, 2012, we provided a supplemental written submission in further response to the Notice and some of the staff’s statements at the June 4, 2012 meeting. To the best of our knowledge, the SEC has not to date made any decision regarding whether to initiate an enforcement proceeding. We cannot predict whether or not any proceedings might be initiated, the amount of any claims that might be asserted or remedies that might be sought by the SEC, or the ultimate outcome of any proceedings that might be initiated. We are currently incurring legal expenses in connection with this matter and anticipate that we will be required to indemnify Mr. Bowers with respect thereto. We maintain directors’ and officers’ insurance policies that may limit our exposure and enable us to recover a portion of any amounts paid with respect to Mr. Bowers’ expenses. However, our insurance carriers have informed us that certain potential losses related to this matter, including our defense costs and any penalties, losses or settlement amounts incurred by us, will not be covered by our insurance policies.

Also as previously disclosed, on August 19, 2011, Hildene Capital Management, LLC filed a purported class action complaint captioned Hildene Capital Management, LLC v. Friedman, Billings, Ramsey Group, Inc. (d/b/a Arlington Asset Investment Corp.), FBR Capital Trust VI, FBR Capital Trust X, Wells Fargo Bank, N.A., as Trustee, and John and Jane Does 1 through 100, No. 11 Civ. 5832, in the United States District Court for the Southern District of New York. On August 15, 2012, the court issued an order granting in part and denying in part the motion to dismiss the amended complaint. Specifically, the court dismissed in their entirety plaintiffs’ derivative claims with prejudice and their claims based on the Racketeering Influenced and Corrupt Organizations Act without prejudice. Moreover, the court dismissed plaintiffs’ remaining claims against the Company for tortious interference, unjust enrichment, and aiding and abetting breach of fiduciary duty, other than to the extent they were based on plaintiffs’ theory that the challenged sale of preferred securities out of the collateralized debt obligations was not permitted by the governing documents, or fell outside the scope of the governing documents or arose from an alleged conflict of interest of co-defendant Well Fargo Bank, N.A. The Company’s answer to the amended complaint was filed on September 17, 2012. We are currently incurring legal expenses in connection with this matter. Our insurance carriers have informed us that potential losses related to this matter based on current claims will not be covered by our insurance policies.

Item 1A. Risk Factors

There is no certainty what effect QE3 will have on the price and liquidity of agency-backed MBS and other securities in which we invest, although the Federal Reserve’s actions could increase the prices of our target assets and reduce the spread on our investments.

On November 25, 2008, the Federal Reserve announced a program to purchase agency-backed MBS in the open market. The stated goal of this program was to provide support to mortgage and housing markets and to foster improved conditions in financial markets more generally. On March 18, 2009, this program was expanded to a target size of $1.25 trillion. The Federal Reserve completed this purchase program in March 2010. In October 2010, the Federal Reserve announced plans for a second round of quantitative easing, and on November 3, 2010, announced that it intended to purchase a further $600 billion of longer-term Treasury securities by the end of the second quarter of 2011, a pace of about $75 billion per month. On September 13, 2012, the U.S. Federal Reserve announced QE3 to expand its holdings of long-term securities by purchasing an additional $40 billion of agency-backed MBS per month until key economic indicators, such as the unemployment rate, showed signs of improvement. This program when combined with existing programs to extend the average maturity of the Federal Reserve’s holdings of securities and reinvest principal payments from the Federal Reserve’s holdings of agency debt and agency-backed MBS into agency-backed MBS, is expected to increase the Federal Reserve’s holdings of long-term securities by $85 billion each month through the end of 2012. The Federal Reserve also announced that it will keep the target federal funds range between zero and 0.25% through at least mid-2015, which is six months longer than previously expected. The Federal Reserve expects these measures to put downward pressure on long-term interest rates. While the Federal Reserve hopes that QE3 will expedite an economic recovery, stabilize prices, reduce unemployment and restart business and household spending, there is no way of knowing what impact QE3 or any future actions by the Federal Reserve will have on the prices and liquidity of agency-backed MBS or other securities in which we invest, although the Federal Reserve’s actions could increase the prices of our target assets and reduce the spread on our investments.

Failure to obtain and maintain an exemption from being regulated as a commodity pool operator could subject us to additional regulation and compliance requirements and may result in fines and other penalties which could materially adversely affect our business and financial condition.

Recently adopted rules under the Dodd-Frank Act establish a comprehensive new regulatory framework for derivative contracts commonly referred to as “swaps.” Under these recently adopted rules, any investment fund that trades in swaps may be considered a “commodity pool,” which would cause its directors to be regulated as “commodity pool operators” ("CPOs"). Under the new rules, which become effective on December 31, 2012 for those who become CPOs solely because of their use of swaps, CPOs must register with the National Futures Association (the "NFA"), which requires compliance with NFA's rules, and are subject to regulation by the U.S. Commodity Futures Trading Commission (the “CFTC”) including with respect to disclosure, reporting, recordkeeping and business conduct.

We use hedging instruments in conjunction with our investment portfolio and related borrowings to reduce or mitigate risks associated with changes in Eurodollar futures, interest rates, mortgage spreads, yield curve shapes and market volatility. These hedging instruments include interest rate swaps, interest rate futures and options on interest rate futures. We do not currently engage in any speculative derivatives activities or other non-hedging transactions using swaps, futures or options on futures. We do not use these instruments for the purpose of trading in commodity interests, and we do not consider our company or its operations to be a commodity pool as to which CPO regulation or compliance is required. We, along with numerous other mortgage REITs, have submitted a no-action letter request to the CFTC seeking exemptive relief for our directors from CPO registration under these new rules. However, at this time, our directors do not intend to register as CPOs with the NFA. While we have reason to believe that the CFTC may provide us with exemptive relief prior to December 31, 2012, there can be no assurance that any such relief will be granted. If exemptive relief is granted, we may be restricted to operating within certain parameters discussed in the no-action letter we submitted to the CFTC. For example, exemptive relief might limit our ability to enter into interest rate hedging transactions if the amount of income we receive from such hedges will exceed five percent of our gross income or the initial margin.

The CFTC has substantial enforcement power with respect to violations of the laws over which it has jurisdiction, including their anti-fraud and anti-manipulation provisions. Among other things, CFTC may suspend or revoke the registration of a person who fails to comply, prohibit such a person from trading or doing business with registered entities, impose civil money penalties, require restitution and seek fines or imprisonment for criminal violations. Additionally, a private right of action exists against those who violate the laws over which CFTC has jurisdiction or who willfully aid, abet, counsel, induce or procure a violation of those laws. In the event we fail to receive exemptive relief from the CFTC on this matter and our directors fail to comply with the regulatory requirements of these new rules, we may be subject to significant fines, penalties and other civil or governmental actions or proceedings, any of which could have a materially adverse effect on our business, financial condition and results of operations.

We cannot predict the impact, if any, on our earnings or cash available for distribution to our stockholders of the FHFA's proposed revisions to Fannie Mae's, Freddie Mac's and Ginnie Mae's existing infrastructures to align the standards and practices of the three entities.

On February 21, 2012, the FHFA released its Strategic Plan for Enterprise Conservatorships, which set forth three goals for the next phase of the Fannie Mae and Freddie Mac conservatorships. These three goals are to (i) build a new infrastructure for the secondary mortgage market, (ii) gradually contract Fannie Mae and Freddie Mac's presence in the marketplace while simplifying and shrinking their operations, and (iii) maintain foreclosure prevention activities and credit availability for new and refinanced mortgages. On October 4, 2012, the FHFA released its white paper entitled Building a New Infrastructure for the Secondary Mortgage Market, which proposes a new infrastructure for Fannie Mae and Freddie Mac that has two basic goals.

The first such goal is to replace the current, outdated infrastructures of Fannie Mae and Freddie Mac with a common, more efficient infrastructure that aligns the standards and practices of the two entities, beginning with core functions performed by both entities such as issuance, master servicing, bond administration, collateral management and data integration. The second goal is to establish an operating framework for Fannie Mae and Freddie Mac that is consistent with the progress of housing finance reform and encourages and accommodates the increased participation of private capital in assuming credit risk associated with the secondary mortgage market.

40

The FHFA recognizes that there are a number of impediments to their goals which may or may not be surmountable, such as the absence of any significant secondary mortgage market mechanisms beyond Fannie Mae, Freddie Mac and Ginnie Mae, and that their proposals are in the formative stages. As a result, it is unclear if the proposals will be enacted. If such proposals are enacted, it is unclear how closely what is enacted will resemble the proposals from the FHFA White Paper or what the effects of the enactment will be in terms of our net asset value, earnings or cash available for distribution to our stockholders.

Basis of Presentation [Abstract]

Basis of Presentation

1. Basis of Presentation:

The consolidated financial statements of Arlington Asset Investment Corp. (Arlington Asset) and its subsidiaries (unless the context otherwise provides, collectively, the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and with the instructions to Form 10-Q. Therefore, they do not include all information required by GAAP for complete financial statements. The interim financial statements reflect all adjustments (consisting only of normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of the results for the periods presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three and nine months ended September 30, 2012 are not necessarily indicative of the operating results for the entire year or any other subsequent interim period. The Company's unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2011.

The preparation of the Company's financial statements in conformity with GAAP requires the Company to make estimates and assumptions affecting the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Although the Company based the estimates and assumptions on historical experience, when available, market information, and on various other factors that the Company believes to be reasonable under the circumstances, management exercises significant judgment in the final determination of the estimates. Actual results may differ from these estimates.

Certain amounts in the consolidated financial statements and notes for prior periods have been reclassified to conform to the current period presentation. These reclassifications had no effect on the results of operations of the Company.

[3] The securities issued by Fannie Mae and Freddie Mac are not rated by any rating agency; however, they are commonly thought of as having an implied rating of "AAA." There is no assurance, particularly given the downgrade of the U.S.'s credit rating to "AA" by Standard & Poors during the quarter ended September 30, 2011, that these securities would receive such a rating if they were ever rated by a rating agency. The weighted-average rating of the Company's private-label senior securities is calculated based on face value of the securities.

  Long-Term Incentive Plan

On April 13, 2011, the Board of Directors adopted the Arlington Asset Investment Corp. 2011 Long-Term Incentive Plan (2011 Plan). The 2011 Plan was approved by the Company's shareholders and became effective on June 2, 2011. Under the 2011 Plan, shares of Class A common stock of the Company may be issued to employees, directors, consultants and advisors of the Company and its affiliates. As of September 30, 2012 and December 31, 2011, 488,948 and 530,519 shares, respectively, remained available for issuance under the 2011 Plan.

Performance-Based Long-Term Incentive Program

On August 13, 2012, the Compensation Committee of the Board of Directors of the Company adopted a performance-based long-term incentive program (Performance-based Program) that provides for the issuance of two types of performance share units (PSUs) from time to time pursuant to the Company's 2011 Plan.  The Performance-based Program is designed to provide an incentive compensation opportunity that balances the Company's internal financial objectives and external market performance.  Eligible participants in the Performance-based Program are the Company's named executive officers.

The Compensation Committee established performance goals under the Performance-based Program. The awards under the Performance-based Program comprise of two types of PSUs: Combined Net Worth Units (Book Value PSUs) and Total Shareholder Return Units (TSR PSUs). The Book Value PSUs are eligible to vest based on the compound annualized growth in the Company's book value per share (i.e., book value change plus dividends on a reinvested basis) during the applicable performance period.  The TSR PSUs are eligible to vest based on the Company's compound annualized total shareholder return (i.e., share price change plus dividends on a reinvested basis) during the applicable performance period.

PSUs do not have any voting rights.  No dividends are paid on outstanding PSUs during the applicable performance period.  Instead, dividend equivalents are accrued on outstanding PSUs during the applicable performance period, deemed invested in shares of Class A common stock and are paid out in shares of Class A common stock at the end of the performance period to the extent that the underlying PSUs vest. Upon settlement, vested PSUs are converted into shares of the Company's Class A common stock on a one-for-one basis. The PSUs and dividend equivalents are settled in whole shares of Class A common stock with a cash payment in lieu of any fractional share.

The right to receive shares of Class A common stock upon vesting of PSUs at the end of the applicable performance period is subject to both continued employment and the achievement of the Company performance goals established by the Compensation Committee. The employment requirement, but not the performance requirement, is waived in the event the awardee dies, becomes disabled or retires; provided, however, that if the awardee dies, becomes disabled or retires before the first anniversary of the grant date, the number of PSUs that are earned under the performance targets are pro rated. If an awardee is terminated without "cause," the Compensation Committee, in the exercise of its discretion, determines whether any of the PSUs have been earned, provided that the Compensation Committee may not approve a payout that exceeds the number of PSUs earned under the performance targets. In the event of a change of control, the number of PSUs that are earned for each performance period are determined immediately prior to the change of control based on actual performance and vests subject to continued employment for the remainder of the original performance period, subject to accelerated vesting in certain circumstances.

Except as described above or as the Compensation Committee at any time may otherwise determine, an awardee will forfeit the right to any PSUs if he or she terminates employment before the payment date.

The Company accounts for the Performance-based Program in accordance with ASC 718. Therefore, the Book Value PSUs are valued at the grant date market value and the estimated compensation cost is recorded over the vesting period. The Company estimates the number of shares to be issued under the Book Value PSUs on a quarterly basis based on the actual and projected results for the remaining vesting period and any adjustments required are recognized retrospectively and over the remaining vesting period.

The Total Shareholder Return PSUs are also valued at the time of grant based on valuation model and the estimated compensation cost is recorded over the vesting period using straight-line basis. The valuation of the Total Shareholder Return PSUs is performed using Monte-Carlo simulation model (Model) using various assumptions including beginning average price, expected volatility, dividend equivalents, dividend yield, and risk-free rate of return. The Model projects stock prices on a daily basis assuming 250 trading days per year. The Model generates many future stock price paths to construct a distribution of where future stock prices might be. No remeasurement of compensation expense is required for the Total Shareholder Return PSUs.

The compensation costs will be reversed if an employee terminates prior to completing the required service period. The estimated shares to be granted under the Performance-based Program are included in the calculation of diluted Earnings Per Share.

On August 13, 2012, the Compensation Committee of the Board of Directors of the Company approved the initial grant of 30,177 Book Value PSUs and 41,735 TSR PSUs to the participants in the Performance-based Program.

For the initial grant, the Compensation Committee awarded PSUs with an aggregate grant date fair value equal to 75% of the awardee's base salary, with 50% of the total grant date fair value represented by Book Value PSUs and 50% of the total grant date fair value represented by TSR PSUs. To facilitate the implementation of the Performance-based Program, the Compensation Committee established both a two-year and three-year performance period for the initial grant of PSUs. A portion of the Book Value PSUs and TSR PSUs will be eligible for vesting at the end of the second year following the grant date, and a portion of the Book Value PSUs and TSR PSUs will be eligible for vesting at the end of the third year following the grant date. The Company anticipates that subsequent PSUs grants will have a three-year performance period.

The actual number of shares of Class A common stock that will be issued to each participant at the end of the applicable performance period will vary between 0% and 200% of the number of PSUs granted, depending on performance results. If the threshold level of performance goals are not achieved, no PSUs are earned. If the initial performance threshold is met, participants earn 50% of the granted PSUs for Company performance at the threshold level, 100% of the granted PSUs for Company performance at the target level and 200% of the granted PSUs for Company performance at the maximum level, with linear interpolation for achievement falling between the performance levels.

The Company recorded $96 in compensation expenses related to the Performance-based Program during the three months ended September 30, 2012.

  Share Repurchases

From time to time, the Company repurchases shares of its Class A common stock under a share repurchase program authorized by the Board of Directors in July 2010 (Repurchase Program), pursuant to which the Company is authorized to repurchase up to 500,000 shares of its Class A common stock.

Repurchases under the Repurchase Program may be made from time to time on the open market and in private transactions at management's discretion in accordance with applicable federal securities laws. The timing of repurchases and the exact number of shares of Class A common stock to be repurchased will depend upon market conditions and other factors. The Repurchase Program is funded using the Company's cash on hand and cash generated from operations.

Income Taxes

5. Income Taxes:

The total income tax provision for the three and nine months ended September 30, 2012 was $450 and $1,271, respectively. The total income tax provision for the three and nine months ended September 30, 2011 was $259 and $1,076, respectively. The Company generated a pre-tax book income of $3,573 and $17,300 for the three and nine months ended September 30, 2012, respectively. The Company generated pre-tax book (loss) income of $(11,384) and $9,309 for the three and nine months ended September 30, 2011, respectively.

The Company's effective tax rate for the nine months ended September 30, 2012 and 2011 was 7.35% and 11.56%, respectively. The effective tax rate during these periods was lower than the highest marginal tax rates due to the realization of deferred tax assets that were offset by a full valuation allowance. The net deferred tax assets, which are offset by a full valuation allowance, include net operating losses (NOLs), which are available to offset the current and future taxable income. The Company recorded an expected tax liability for these periods due to the expected alternative minimum taxes. Limitations prevent the Company from using its NOLs to fully offset its taxable income for alternative minimum tax purposes. The Company expects to realize additional tax benefits of NOLs in 2012, which are reflected in the Company's projected effective tax rate for the year, along with a corresponding release of the valuation allowance previously recorded against these losses. The Company will continue to provide a valuation allowance against the other deferred tax assets to the extent the Company believes that it is more likely than not that the benefits will not be realized in the future. The Company will continue to assess the need for a valuation allowance at each reporting date.

The Company is subject to examination by the U.S. Internal Revenue Service (IRS), and other taxing authorities in jurisdictions where the Company has significant business operations, such as Virginia. An IRS examination of the Company's tax years 2009 and 2010 is currently on-going.

Earnings Per Share

6. Earnings Per Share:

Basic earnings per share includes no dilution and is computed by dividing net income or loss available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share includes the impact of dilutive securities such as stock options and unvested shares of restricted stock. The following tables present the computations of basic and diluted earnings per share for the periods indicated:

⁽¹⁾ The Company's MBS portfolio was primarily comprised of fixed-rate MBS at September 30, 2012 and December 31, 2011. The weighted-average coupon of the MBS portfolio at September 30, 2012 and December 31, 2011 was 4.35% and 4.85%, respectively.

⁽²⁾ As of September 30, 2012 and December 31, 2011, the Company's MBS investments with a fair value of $963,285 and $731,432, respectively, were pledged as collateral for repurchase agreements.

⁽³⁾ The securities issued by Fannie Mae and Freddie Mac are not rated by any rating agency; however, they are commonly thought of as having an implied rating of "AAA." There is no assurance, particularly given the downgrade of the U.S.'s credit rating to "AA" by Standard & Poors during the quarter ended September 30, 2011, that these securities would receive such a rating if they were ever rated by a rating agency. The weighted-average rating of the Company's private-label senior securities is calculated based on face value of the securities.

2. Financial Instruments:

Fair Value of Financial Instruments

The accounting principles related to fair value measurements define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, not adjusted for transaction costs. Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures (ASC 820), establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3) as described below:

Level 1 Inputs— Unadjusted quoted prices in active markets for identical assets or liabilities that are accessible by the Company;

Level 2 Inputs— Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; and

Level 3 Inputs— Unobservable inputs for the asset or liability, including significant assumptions of the Company and other market participants.

The Company determines fair values for the following assets and liabilities:

Mortgage-backed securities (MBS), at fair value—

Agency-backed MBS - The Company's agency-backed MBS, the principal and interest payments on which are guaranteed by the Federal National Mortgage Association (Fannie Mae) or the Federal Home Loan Mortgage Corporation (Freddie Mac), are generally classified within Level 2 of the fair value hierarchy as they are valued after considering quoted market prices provided by a broker or dealer, or alternative pricing sources with reasonable levels of price transparency. The Company reviews broker or pricing service quotes to determine whether the quotes are relevant, for example, whether an active market exists to provide price transparency or whether the quote is an indicative price or a binding offer. The independent brokers and dealers providing market prices are those who make markets in these financial instruments.

Private-label MBS - The Company classifies private-label MBS within Level 3 of the fair value hierarchy because they trade infrequently and, therefore, have little or no price transparency. The Company utilizes present value techniques based on estimated cash flows of the instrument taking into consideration various assumptions derived by management and other assumptions used by other market participants. These assumptions are corroborated by evidence such as historical data, risk characteristics, transactions in similar instruments, and completed or pending transactions, when available. The significant inputs in the Company's valuation process include default rate, loss severity, prepayment rate and discount rate. In general, significant increases (decreases) in default rate, loss severity or discount rate, in isolation, would result in a significantly lower (higher) fair value measurement.  However, significant increases (decreases) in prepayment rate may result in a significantly higher (lower) fair value measurement. It is difficult to generalize the interrelationships between these significant inputs as the actual results could differ considerably on an individual security basis.  For example, an increase in the default rate may not increase the loss severity rate if actual losses are lower than the average.  Also, changes in discount rates may be greatly influenced by market expectation at any given point based upon many variables not directly related to the MBS market.  Therefore, each significant input is closely analyzed to ascertain the reasonableness for the Company's valuation purposes.

Establishing fair value is inherently subjective given the volatile and sometimes illiquid markets for these private-label MBS and requires management to make a number of assumptions, including assumptions about the future of interest rates, prepayment rates, discount rates, credit loss rates, and the timing of cash flows and credit losses. The assumptions the Company applies are specific to each security. Although the Company relies on the internal calculations to compute the fair value of these private-label MBS, the Company requests and considers indications of value (mark) from third-party dealers to assist in the valuation process.

Securities sold but not yet purchased, at fair value—The Company's securities sold but not yet purchased, at fair value, represent obligations of the Company to deliver a specified MBS at a contracted price, which create a liability to purchase that MBS at prevailing prices in order to deliver the MBS in satisfaction of this obligation. The Company's liability for the purchase of the MBS to be delivered is measured at the fair value of the MBS as of the date of the financial statements. However, these transactions expose the Company to price risk until settled, as the Company's ultimate cost to satisfy the delivery of securities sold but not yet purchased, at fair value, may exceed the amount reflected in the consolidated balance sheet. The Company classifies MBS sold but not yet purchased, at fair value, within Level 2 of the fair value hierarchy, as they are valued after considering quoted market prices provided by a broker or dealer, or alternative pricing sources, with reasonable levels of price transparency. The Company reviews broker or pricing service quotes to determine whether the quotes are relevant, for example, whether an active market exists to provide price transparency or whether the quote is an indicative price or a binding offer. The independent brokers and dealers providing market prices are those who make markets in these financial instruments.

Other investments—The Company's other investments consist of investments in equity securities, investment funds, interest-only MBS, and other MBS-related securities. Interest-only MBS and residual interest in a securitization of which the Company is not considered the primary beneficiary are classified within Level 3 of the fair value hierarchy.

Derivative instruments—In the normal course of the Company's operations, the Company is a party to various financial instruments that are accounted for as derivatives in accordance with ASC 815, Derivatives and Hedging (ASC 815). The derivative instruments that trade in active markets or exchanges are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. Other derivative instruments are generally classified within Level 2 of the fair value hierarchy because they are valued using broker or dealer quotations, which are model-based calculations based on market-based inputs, including, but not limited to, contractual terms, market prices, yield curves, credit curves, measures of volatility, prepayment rates and correlations of such inputs.

Other—Cash and cash equivalents, interest receivable, deposits, other receivable, interest payable, accounts payable, accrued expenses and other liabilities are reflected in the consolidated balance sheets at their amortized cost, which approximates fair value because of the short term nature of these instruments and classified within Level 1 of the fair value hierarchy.

 —Sold securities receivable, repurchase agreements and purchase securities payable are reflected in the consolidated balance sheets at the cost basis, which approximates fair value because of the short term nature of these instruments and classified within Level 2 of the fair value hierarchy.

 —Long-term debt represents a remaining balance of trust preferred debt issued by the Company which approximates fair value due to the nature of the debenture and is classified within Level 3 of the fair value hierarchy.

The estimated fair values of the Company's financial instruments are as follows:

There were no transfers of securities in or out of Levels 1, 2 or 3 during the three or nine months ended September 30, 2012 or the year ended December 31, 2011.

Level 3 Financial Assets and Liabilities

Financial Instruments Measured at Fair Value on a Recurring Basis

As of September 30, 2012, the fair value of the Company's Level 3, available-for-sale, private-label MBS was $196,816. These securities are primarily senior and re-REMIC tranches in securitization trusts issued between 2005 and 2010. The senior securities represent interests in securitizations that have the first right to cash flows and absorb losses last. The re-REMIC securities represent interests in re-securitizations of senior MBS and pro-rata mezzanine securities. For re-REMIC securities, the cash flows from, and any credit losses absorbed by, the underlying MBS are allocated among the re-REMIC securities issued in the re-securitization transactions based on the re-REMIC structure. For example, prime and non-prime residential senior securities have been resecuritized to create a two-tranche structure with a re-REMIC senior security and a re-REMIC subordinated security. In these re-REMIC securities, all principal payments from the underlying securities are directed to the re-REMIC senior security until the face value is fully paid off. Thereafter, all principal payments are directed to the re-REMIC subordinated security. For pro-rata mezzanine securities, principal payments from the underlying MBS are typically allocated concurrently and proportionally to the mezzanine securities along with senior securities. The re-REMIC subordinated and mezzanine securities absorb credit losses, if any, first; however, these credit losses occur only when credit losses exceed the credit protection provided to the underlying securities. Senior, re-REMIC and mezzanine securities receive interest while any face value is outstanding.

As of September 30, 2012, the Company's senior securities and re-REMIC securities were collateralized by residential Prime and Alt-A mortgage loans and had a weighted-average original loan-to-value of 71%, weighted-average original FICO score of 729, weighted-average three-month prepayment rate of 20% and weighted-average three-month loss severities of 43%. These underlying collateral loans had a weighted-average coupon rate of 4.85%. These securities are currently rated below investment grade. The significant unobservable inputs for the valuation model include the following weighted-averages:

	September 30, 2012						December 31, 2011
	Senior Securities			Re-REMIC Securities			Senior Securities			Re-REMIC Securities
Discount rate		6.80	%		8.59	%		7.00	%		8.75	%
Default rate		9.30	%		5.16	%		10.30	%		5.55	%
Loss severity rate		57.50	%		44.66	%		60.00	%		43.06	%
Prepayment rate		16.30	%		14.62	%		17.30	%		15.20	%

The ranges of the significant unobservable inputs for the valuation model were as follows as of the dates indicated:

	September 30, 2012						December 31, 2011
	Senior Securities			Re-REMIC Securities			Senior Securities			Re-REMIC Securities
Discount rate		6.80	%		7.15 – 13.73	%		7.00	%		7.45 – 13.73	%
Default rate		9.30	%		1.75 – 11.00	%		10.30	%		2.10 – 13.00	%
Loss severity rate		57.50	%		28.21 – 57.50	%		60.00	%		28.18 – 57.50	%
Prepayment rate		16.30	%		7.75 – 21.05	%		17.30	%		9.60 – 21.00	%

Level 3 Financial Instruments Measured at Fair Value on a Non-Recurring Basis

The Company also measures certain financial assets at fair value on a non-recurring basis. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairments. Due to the nature of these financial assets, enterprise values are primarily used to value these financial assets. In determining the enterprise value, the Company analyzes various financial, performance and market factors to estimate fair value, including where applicable, market trading activity. As a result, these financial assets are classified within Level 3 of the fair value hierarchy. As of September 30, 2012, these financial assets are classified within the other investments category and represent the Company's interest in non-public equity securities and investment funds. For the three and nine months ended September 30, 2012, the Company recorded a loss of $64 in the carrying value of these financial assets. For the nine months ended September 30, 2011, the Company recorded a loss of $85 in the carrying value of these financial assets. For the three months ended September 30, 2011, there were no changes to the carrying value of these financial assets.

⁽¹⁾ The Company's MBS portfolio was primarily comprised of fixed-rate MBS at September 30, 2012 and December 31, 2011. The weighted-average coupon of the MBS portfolio at September 30, 2012 and December 31, 2011 was 4.35% and 4.85%, respectively.

⁽²⁾ As of September 30, 2012 and December 31, 2011, the Company's MBS investments with a fair value of $963,285 and $731,432, respectively, were pledged as collateral for repurchase agreements.

⁽³⁾ The securities issued by Fannie Mae and Freddie Mac are not rated by any rating agency; however, they are commonly thought of as having an implied rating of "AAA." There is no assurance, particularly given the downgrade of the U.S.'s credit rating to "AA" by Standard & Poors during the quarter ended September 30, 2011, that these securities would receive such a rating if they were ever rated by a rating agency. The weighted-average rating of the Company's private-label senior securities is calculated based on face value of the securities.

The Company has generally purchased private-label MBS at a discount. The Company, at least on a quarterly basis, estimates the future expected cash flows based on the Company's observation of current information and events and applying a number of assumptions related to prepayment rates, interest rates, default rates, and the timing and amount of cash flows and credit losses. These assumptions are difficult to predict as they are subject to uncertainties and contingencies related to future events that may impact the Company's estimates and its interest income.

Interest income on the private-label MBS that were purchased at a discount to face value is recognized based on the security's expected effective interest rate. At acquisition, the accretable yield is calculated as the difference between the undiscounted expected cash flows and the purchase price which is expected to be accreted into interest income over the remaining life of the security on a level-yield basis. The difference between the contractually required payments and the undiscounted expected cash flows represents the non-accretable difference. Based on actual payment activities and changes in estimates of undiscounted expected future cash flows, the accretable yield and the non-accretable difference can change over time. Significant increases in the amount or timing of undiscounted expected future cash flows are recognized prospectively as an adjustment to the accretable yield.

The following table presents the changes in the accretable yield on available-for-sale, private-label MBS for the three and nine months ended September 30, 2012 and 2011.

	Three Months Ended September 30,						Nine Months Ended September 30,
