AMERICAN CAPITAL AGENCY CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Unaudited Interim Consolidated Financial Statements

The interim consolidated financial statements of American Capital Agency Corp. (together with its consolidated subsidiary, is referred throughout this report as the “Company”, “we”, “us” and “our”) are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

Our unaudited consolidated financial statements include the accounts of our wholly-owned subsidiary, American Capital Agency TRS, LLC, and variable interest entities for which the Company is the primary beneficiary. Significant intercompany accounts and transactions have been eliminated. In the opinion of management, all adjustments, consisting solely of normal recurring accruals, necessary for the fair presentation of financial statements for the interim period have been included. The current period’s results of operations are not necessarily indicative of results that ultimately may be achieved for the year. Through June 30, 2011, there has been no activity in American Capital Agency TRS, LLC.

Note 2. Organization

We were organized in Delaware on January 7, 2008, and commenced operations on May 20, 2008 following the completion of our initial public offering (“IPO”). Our common stock is traded on The NASDAQ Global Select Market under the symbol “AGNC”.

We have elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). As such, we are required to distribute annually 90% of our taxable net income. As long as we qualify as a REIT, we will generally not be subject to U.S. federal or state corporate taxes on our taxable net income to the extent that we distribute all of our annual taxable net income to our stockholders. We are externally managed by American Capital AGNC Management, LLC (our “Manager”), an affiliate of American Capital, Ltd. (“American Capital”).

We earn income primarily from investing in residential mortgage pass-through securities and collateralized mortgage obligations (“CMOs”) on a leveraged basis. These investments consist of securities for which the principal and interest payments are guaranteed by government-sponsored entities (“GSEs”), such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or by a U.S. Government agency, such as the Government National Mortgage Association (“Ginnie Mae”). We refer to these types of securities as agency securities and the specific agency securities in which we invest as our investment portfolio.

Our principal objective is to preserve our net asset value while generating attractive risk-adjusted returns for distribution to our stockholders through regular quarterly dividends from our net interest income, which is the spread between the interest income earned on our interest earning assets and the interest costs of our borrowings and hedging activities, and net realized gains and losses on our investments and other supplemental hedging activities. We fund our investments primarily through short-term borrowings structured as repurchase agreements.

Note 3. Summary of Significant Accounting Policies

Investments in Agency Securities

Accounting Standards Codification (“ASC”) Topic 320,Investments—Debt and Equity Securities (“ASC 320”), requires that at the time of purchase, we designate a security as held-to-maturity, available-for-sale or trading, depending on our ability and intent to hold such security to maturity. Securities classified as trading and available-for-sale are reported at fair value, while securities classified as held-to-maturity are reported at amortized cost. We may, from time to time, sell any of our agency securities as part of our overall management of our investment portfolio. Accordingly, we typically designate our agency securities as available-for-sale. All securities classified as available-for-sale are reported at fair value, with unrealized gains and losses reported in other comprehensive income (loss) (“OCI”), a component of stockholders’ equity. Upon the sale of a security, we determine the cost of the security and the amount of unrealized gains or losses to reclassify out of accumulated OCI into earnings based on the specific identification method.

Interest-only securities and inverse interest-only securities (collectively referred to as “interest-only securities”) represent our right to receive a specified proportion of the contractual interest flows of specific agency and CMO securities. Principal-only securities represent our right to receive the contractual principal flows of specific agency and CMO securities. Interest-only and principal-only securities are measured at fair value through earnings in gain (loss) on derivative instruments and trading securities, net in our consolidated statements of operations and comprehensive income. Our investments in interest-only and principal-only securities are included in agency securities, at fair value on the accompanying consolidated balance sheets.

We estimate the fair value of our agency securities based on a market approach using Level 2 inputs from third-party pricing services and dealer quotes. The third-party pricing services use pricing models that incorporate such factors as coupons, primary and secondary mortgage rates, prepayment speeds, spread to the Treasury and interest rate swap curves, convexity, duration, periodic and life caps and credit enhancements. The dealer quotes incorporate common market pricing methods, including a spread measurement to the Treasury or interest rate swap curve as well as underlying characteristics of the particular security including coupon, periodic and life caps, rate reset period, issuer, additional credit support and expected life of the security.

We evaluate securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. Based on the criteria in ASC 320, the determination of whether a security is other-than-temporarily impaired involves judgments and assumptions based on subjective and objective factors. When an agency security is impaired, an OTTI is considered to have occurred if (i) we intend to sell the agency security (i.e. a decision has been made as the reporting date) or (ii) it is more likely than not that we will be required to sell the agency security before recovery of its amortized cost basis. If we intend to sell the security or if it is more likely than not that we will be required to sell the agency security before recovery of its amortized cost basis, the entire amount of the impairment loss, if any, is recognized in earnings as a realized loss and the cost basis of the security is adjusted to its fair value.

We did not recognize any OTTI charges on any of our agency securities for six months ended June 30, 2011 and 2010.

Interest Income

Interest income is accrued based on the outstanding principal amount of the agency securities and their contractual terms. Premiums and discounts associated with the purchase of agency securities are amortized or accreted into interest income over the projected lives of the securities, including contractual payments and estimated prepayments using the interest method in accordance with ASC Subtopic 310-20,Receivables—Nonrefundable Fees and Other Costs (“ASC 310-20”).

We estimate long-term prepayment speeds using a third-party service and market data. The third-party service estimates prepayment speeds using models that incorporate the forward yield curve, current mortgage rates, current mortgage rates of the outstanding loans, loan age, volatility and other factors. We review the

7

prepayment speeds estimated by the third-party service and compare the results to market consensus prepayment speeds, if available. We also consider historical prepayment speeds and current market conditions to validate the reasonableness of the prepayment speeds estimated by the third-party service and based on our Manager’s judgment we may make adjustments to their estimates. Actual and anticipated prepayment experience is reviewed quarterly and effective yields are recalculated when differences arise between the previously estimated future prepayments and the amounts actually received plus current anticipated future prepayments. If the actual and anticipated future prepayment experience differs from our prior estimate of prepayments, we are required to record an adjustment in the current period to the amortization or accretion of premiums and discounts for the cumulative difference in the effective yield through the reporting date.

In addition, pursuant to ASC 310-20, the yield on our adjustable rate securities assumes that the securities reset at a rate equal to the underlying index rate in effect as of the date we acquired the security plus the stated margin. Consequently, future reset rate assumptions incorporated in our asset yields may differ materially from future reset rates implied by the forward yield curve and the actual reset rates ultimately achieved. Further, notwithstanding changes to our actual and projected constant prepayment rate (“CPR”) assumptions, the lower our reset rate assumption is pursuant to ASC 310-20 than the current fixed rate in effect, the greater the rate of premium amortization we will recognize over the initial fixed rate period.

Our adjustable rate portfolio was acquired for a premium above par value and most securities were acquired during a period of historically low index rates. Accordingly, the majority of the premium balance on our adjustable rate securities will be amortized prior to their first reset date, regardless of actual or forecasted prepayment speeds and changes in the underlying index rates prior to actual reset. Adjustable rate securities acquired during a different interest rate environment may experience a different premium amortization pattern even as current index rates remain near their historical lows.

Derivative and other Hedging Instruments

We maintain a risk management strategy, under which we use a variety of strategies to hedge some of our exposure to interest rate risk. The objective of our risk management strategy is to reduce fluctuations in book value and generate additional income distributable to stockholders. In particular, we attempt to mitigate the risk of the cost of our variable rate liabilities increasing during a period of rising interest rates. The principal instruments that we use are interest rate swaps and options to enter into interest rate swaps (“interest rate swaptions”). We also purchase or sell to-be-announced forward contracts (“TBAs”), forward contracts for specified agency securities, U.S. Treasury securities and U.S. Treasury futures contracts, purchase or write put or call options on TBA securities and invest in other types of mortgage derivatives, such as interest-only securities, and synthetic total return swaps, such as the Markit IOS Synthetic Total Return Swap Index (“Markit IOS Index”).

We account for derivative instruments in accordance with ASC Topic 815,Derivatives and Hedging (“ASC 815”). ASC 815 requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet and to measure those instruments at fair value. Hedging instruments that are not derivatives under ASC 815 are accounted for in accordance with ASC 320.

The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives that are intended to hedge exposure to variability in expected future cash flows are considered cash flow hedges. For derivatives designated in qualifying cash flow hedging relationships, the effective portion of the fair value adjustments is initially recorded in OCI (a component of stockholders’ equity) and reclassified to income at the time that the hedged transactions affect earnings. The ineffective portion of the fair value adjustments is immediately recognized in gain (loss) on derivative instruments and trading securities, net. When the underlying hedged transaction ceases to exist, any amounts that have been previously recorded in accumulated OCI would be reclassified to net income and all subsequent changes in the fair value of the instrument would be included in gain (loss) on derivative instruments and trading securities, net for each period until the derivative instrument matures or is settled. For derivatives not designated in hedging

8

relationships under ASC 815, the fair value adjustments are recorded in gain (loss) on derivative instruments and trading securities, net. Derivatives in a gain position are reported as derivative assets at fair value and derivatives in a loss position are reported as derivative liabilities at fair value in our consolidated balance sheets. In our consolidated statements of cash flows, cash receipts and payments related to derivative instruments are classified according to the underlying nature or purpose of the derivative transaction, generally in the operating section for derivatives designated in hedging relationships and the investing section for derivatives not designated in hedging relationships.

The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. We attempt to minimize this risk by limiting our counterparties to major financial institutions with acceptable credit ratings and monitoring positions with individual counterparties.

Interest rate swap agreements

We use interest rate swaps to hedge the variable cash flows associated with short-term borrowings made under our repurchase agreement facilities. We generally enter into such derivatives with the intention of qualifying for hedge accounting under ASC 815.

We estimate the fair value of interest rate swaps based on inputs from a third-party pricing model. The third-party pricing model incorporates such factors as the Treasury curve, LIBOR rates, and the pay rate on the interest rate swaps. We also incorporate both our own and our counterparties’ nonperformance risk in estimating the fair value of our interest rate swap and swaption agreements. In considering the effect of nonperformance risk, we consider the impact of netting and credit enhancements, such as collateral postings and guarantees, and have concluded that our own and our counterparty risk is not significant to the overall valuation of these agreements.

Interest rate swaptions

We may purchase interest rate swaptions to help mitigate the potential impact of increases or decreases in interest rates on the performance of our investment portfolio (referred to as “convexity risk”). The interest rate swaptions provide us the option to enter into an interest rate swap agreement for a predetermined notional amount, stated term and pay and receive interest rates in the future. The premium paid for interest rate swaptions is reported as an asset in our consolidated balance sheets. The premium is valued at an amount equal to the fair value of the swaption that would have the effect of closing the position adjusted for nonperformance risk, if any. The difference between the premium and the fair value of the swaption is reported in gain (loss) on derivative instruments and trading securities, net in our consolidated statement of operations and comprehensive income. If a swaption expires unexercised, the loss on the swaption would be equal to the premium paid. If we sell or exercise a swaption, the realized gain or loss on the swaption would be equal to the difference between the cash or the fair value of the underlying interest rate swap received and the premium paid.

We estimate the fair value of interest rate swaptions based on the fair value of the future interest rate swap that we have the option to enter into as well as the remaining length of time that we have to exercise the option.

TBA securities

A TBA security is a futures contract for the purchase or sale of agency securities at a predetermined price, face amount, issuer, coupon and stated maturity on an agreed-upon future date. The specific agency securities delivered into the contract upon the settlement date, published each month by the Securities Industry and Financial Markets Association, are not known at the time of the transaction. TBA securities are exempt from ASC 815 and are accounted for under ASC 320 if there is no other way to purchase or sell that security, if delivery of that security and settlement will occur within the shortest period possible for that type of security and if it is probable at inception and throughout the term of the individual contract that physical delivery of the

9

security will occur (referred to as the “regular-way” exception). Alternatively, we may designate the TBA security as a qualifying cash flow hedge under ASC 815 if the regular-way exception is not met and at the time of the purchase or sale of the security, and throughout the term of the individual contract, it is probable that the forecasted transaction will occur and the hedging relationship is expected to be highly effective. For TBA security contracts that we have entered into, we have generally not asserted that physical settlement is probable or that the forecasted transaction is probable of occurring and, therefore, we typically have not designated these forward commitments as hedging instruments. Realized and unrealized gains and losses associated with TBA contracts not subject to the regular-way exception or not designated as hedging instruments are recognized in our consolidated statement of operations and comprehensive income in the line item gain (loss) on derivative instruments and trading securities, net.

We estimate the fair value of TBA securities based on similar methods used to value agency securities.

Put and call options on TBA securities

We may purchase put and call options on TBA securities to hedge against short-term changes in interest rates. Under a purchased put option, we have the right to sell to the counterparty a specified TBA security at a predetermined price on the option exercise date in exchange for a premium at execution. Under a purchased call option, we have the right to purchase from the counterparty a specified TBA security at a predetermined price on the option exercise date in exchange for a premium at execution. The premium paid for a put or call option is reported as an asset in our consolidated balance sheets. The premium is valued at an amount equal to the fair value of the option that would have the effect of closing the position adjusted for nonperformance risk, if any. The difference between the premium and the fair value of the option is reported in gain (loss) on derivative instruments and trading securities, net in our consolidated statement of operations and comprehensive income. When a purchased put or call option expires unexercised, a realized loss is reported in our consolidated statement of operations and comprehensive income equal to the premium paid. When a purchased put or call option is exercised, a realized gain or loss is reported in our consolidated statement of operations and comprehensive income equal to the difference between the premium paid and the fair value of the exercised put or call option. In addition, a derivative asset is recorded in our consolidated balance sheet for the TBA security resulting from the put or call option exercise.

We may also write put and call options on TBA securities. Under a written put option, the counterparty has the right to sell us a specified TBA security at a predetermined price on the option exercise date in exchange for a premium at execution. Under a written call option, the counterparty has the right to purchase from us a specified TBA security at a predetermined price on the option exercise date in exchange for a premium at execution. The premium received from writing a put or call option is reported as a liability in our consolidated balance sheets. The premium is valued at an amount equal to the fair value of the option that would have the effect of closing the position adjusted for nonperformance risk, if any. The difference between the premium and the fair value of the option is reported in gain (loss) on derivative instruments and trading securities, net in our consolidated statement of operations and comprehensive income. When a written put or call option expires unexercised, a realized gain is reported in our consolidated statement of operations equal to the premium received. When we terminate a written put or call option, a realized gain or loss is reported in our consolidated statement of operations equal to the difference between the termination payment and the premium received. When a written put or call option is exercised, a realized gain or loss is reported in our consolidated statement of operations equal to the difference between the premium received and the fair value of the exercised put or call option. In addition, a derivative asset or liability is recorded in our consolidated balance sheet for the TBA security resulting from the put or call option exercise.

We estimate the fair value of put and call options on TBA securities based on the fair value of the underlying TBA security as well as the remaining length of time to exercise the option.

Forward commitments to purchase or sell specified agency securities

We may enter into a forward commitment to purchase or sell specified agency securities as a means of acquiring assets or as a hedge against short-term changes in interest rates. Contracts for the purchase or sale of specified agency securities are accounted for as derivatives if the delivery of the specified agency security and settlement extends beyond the shortest period possible for that type of security. We may designate the forward commitment as a qualifying cash flow hedge if at the time of the purchase or sale of the security, and throughout the term of the individual contract, it is probable that physical delivery of the security will occur. Realized and unrealized gains and losses associated with forward commitments not designated as hedging instruments are recognized in our consolidated statement of operations and comprehensive income in the line item gain (loss) on derivative instruments and trading securities, net.

We estimate the fair value of forward commitments to purchase or sell specified agency securities based on similar methods used to value agency securities as well as the remaining length of time of the forward commitment.

U.S. Treasury securities

We may purchase or sell short U.S. Treasury securities and U.S. Treasury futures contracts to help mitigate the potential impact of changes in interest rates on the performance of our portfolio. We may borrow securities to cover short sales of U.S. Treasury securities under reverse repurchase agreements. We account for these as securities borrowing transactions and recognize an obligation to return the borrowed securities at fair value on the balance sheet based on the value of the underlying borrowed securities as of the reporting date. Realized and unrealized gains and losses associated with purchases and short sales of U.S. Treasury securities are recognized in gains (losses) on derivative instruments and trading securities, net in our consolidated statements of operations and comprehensive income.

Total return swaps

We may enter into total return swaps to obtain exposure to a security or market sector without owning such security or investing directly in that market sector. Total return swaps are agreements in which there is an exchange of cash flows whereby one party commits to make payments based on the total return (coupon plus the mark-to-market movement) of an underlying instrument or index in exchange for fixed or floating rate interest payments. To the extent the total return of the instrument or index underlying the transaction exceeds or falls short of the offsetting interest rate obligation, we will receive a payment from or make a payment to the counterparty.

The primary total return swap index in which we invest is the Markit IOS Index. Total return swaps based on the Markit IOS index are intended to synthetically replicate the performance of interest-only securities. We determine the fair value of our total return swaps based on published index prices. Realized and unrealized gains and losses associated with changes in market value of the underlying index and coupon interest are recognized in gain (loss) on derivative instruments and trading securities, net in our consolidated statements of operations and comprehensive income.

Variable Interest Entities

ASC Topic 810,Consolidation(“ASC 810”), requires a qualitative assessment in determining the primary beneficiary of a variable interest entities (“VIEs”) and ongoing assessments of control over such entities as well as additional disclosures for entities that have variable interests in VIEs.

We may enter into transactions involving a CMO trust (e.g. a VIE) whereby we transfer agency securities to an investment bank in exchange for cash proceeds and at the same time enter into a commitment with the same investment bank to purchase to-be-issued securities collateralized by the agency securities transferred. We will consolidate a CMO trust (as it relates to the assets transferred or contributed by us and the related liabilities issued by the trust) if we are the CMO trust’s primary beneficiary; that is, if we have a variable interest (or

11

combination of variable interests) that provides us with a controlling financial interest in the CMO trust. An entity is deemed to have a controlling financial interest if the entity has the power to direct the activities of a VIE that most significantly impacts the VIE’s economic performance and the obligation to absorb losses of or right to receive benefits from the VIE that could potentially be significant to the VIE. In determining if we have a controlling financial interest, we evaluate whether we share the power to control the selection of financial assets transferred to the CMO trust with an unrelated party. We may share power in the selection of assets for certain CMO trusts (i.e., both we and the unrelated party must consent to the transfer of such assets to the CMO trust); however, if our economic interest in the CMO trust is disproportionate to the shared power, we may be deemed to be the primary beneficiary.

Recent Accounting Pronouncements

In April 2011, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2011-03,Transfers and Servicing (Topic 860): Reconsideration of Effective Control for Repurchase Agreements (“ASU 2011-03”),which is intended to improve the accounting for repurchase agreements by removing from the assessment of effective control the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets on substantially the agreed terms, even in the event of default by the transferee, as well as implementation guidance related to that criterion. ASU 2011-03 is effective for the first interim or annual period beginning on or after December 15, 2011 and the guidance should be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date. Early adoption is not permitted. We do not believe the adoption of ASU 2011-03 will have a material impact on our consolidated financial statements.

In May 2011, the FASB issued ASU No. 2011-04,Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”)which largely aligns fair value measurement and disclosure requirements between International Financial Reporting Standards and US GAAP. For US GAAP, the update mainly represents clarifications to Topic 820 as well as some instances where a particular principle or requirement for measuring fair value or disclosing information about fair value measurements has changed. ASU 2011-04 clarifies that (i) the highest and best use concept only applies to nonfinancial assets (ii) an instrument classified in shareholders’ equity should be measured from the perspective of a market participant holding that instrument as an asset and (iii) quantitave disclosure is required for unobservable inputs used in Level 3 measurements. ASU 2011-04 changes the guidance in Topic 820 so that (i) the fair value of a group of financial assets and financial liabilities with similar risk exposures may be measured on the basis of the entity’s net risk exposure (ii) premiums or discounts may be applied in a fair value measurement under certain circumstances but blockage factors are not permitted and (iii) additional Level 3 disclosures are required, including a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs. ASU 2011-04 is effective for interim and annual periods beginning after December 15, 2011. Early application by public entities is not permitted. We do not believe the adoption of ASU 2011-04 will have a material impact on our consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05,Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”), which is intended to make the presentation of items within OCI more prominent. ASU 2011-05 requires companies to present comprehensive income in either one continuous statement or two separate but consecutive financial statements. Upon the effectiveness of ASU 2011-05, companies will no longer be allowed to present OCI in the statement of stockholders’ equity. In addition, reclassification adjustments between OCI and net income must be presented seperately on the face of the financial statements. The new guidance does not change the components of OCI or the calculation of earnings per share. ASU 2011-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. Early adoption is permitted and the amendments should be applied retrospectively. We do not believe the adoption of ASU 2011-05 will have a material impact on our consolidated financial statements.

Reclassifications

Certain prior period amounts in the consolidated financial statements have been reclassified to conform to the current period presentation.

Actual maturities of agency securities are generally shorter than the stated contractual maturities. Actual maturities are affected by the contractual lives of the underlying mortgages, periodic principal payments and principal prepayments. The following table summarizes our agency securities classified as available-for-sale as of June 30, 2011 and December 31, 2010, according to their estimated weighted average life classification (dollars in thousands):

	As of June 30, 2011							As of December 31, 2010
Weighted Average Life	Fair Value		Amortized Cost		Weighted Average Coupon			Fair Value		Amortized Cost		Weighted Average Coupon
Less than or equal to one year	$	43,212	$	43,350		3.81	%	$	—	$	—		—	%
Greater than one year and less than or equal to three years		1,056,763		1,035,249		4.95	%		133,123		132,520		5.05	%
Greater than three years and less than or equal to five years		4,188,329		4,134,240		4.48	%		3,841,282		3,821,992		4.92	%
Greater than five years		34,390,359		34,214,673		4.19	%		9,479,136		9,526,980		4.31	%
Total	$	39,678,663	$	39,427,512		4.24	%	$	13,453,541	$	13,481,492		4.49	%

The weighted average life of our interest-only securities was 5.4 and 6.2 years as of June 30, 2011 and December 31, 2010, respectively. The weighted average life of our principal-only securities was 4.0 years as of June 30, 2011.

The weighted average lives of the agency securities as of June 30, 2011 and December 31, 2010 incorporates anticipated future prepayment assumptions. As of June 30, 2011, our weighted average expected constant prepayment rate (“CPR”) over the remaining life of our aggregate investment portfolio is 10%. Our estimates differ materially for different types of securities and thus individual holdings have a wide range of projected CPRs. We estimate long-term prepayment assumptions for different securities using third-party services and market data. These third-party services estimate prepayment speeds using models that incorporate the forward yield curve, current mortgage rates, mortgage rates of the outstanding loans, loan age, volatility and other factors. We review the prepayment speeds estimated by the third-party services and compare the results to market consensus prepayment speeds, if available. We also consider historical prepayment speeds and current market conditions to validate reasonableness. As market conditions may change rapidly, we use our judgment in making adjustments for different securities. Various market participants could use materially different assumptions.

Our agency securities classified as available-for-sale are reported at fair value, with unrealized gains and losses excluded from earnings and reported in OCI, a component of stockholders’ equity. The following table summarizes changes in accumulated OCI for available-for-sale securities for the three and six months ended June 30, 2011 and 2010 (in thousands):

	Beginning Balance			Unrealized Gains and (Losses)		Reversal of Prior Period Unrealized (Gains) and Losses on Realization			Ending Balance
Three months ended June 30, 2011	$	(67,751	)		412,252		(93,350	)	$	251,151
Three months ended June 30, 2010	$	37,951			88,547		(29,063	)	$	97,435
Six months ended June 30, 2011	$	(27,950	)		376,671		(97,570	)	$	251,151
Six months ended June 30, 2010	$	36,018			117,888		(56,471	)	$	97,435

The following table presents the gross unrealized loss and fair values of our available-for-sale agency securities by length of time that such securities have been in a continuous unrealized loss position as of June 30, 2011 and December 31, 2010 (in thousands):

	Unrealized Loss Position For
	Less than 12 Months					12 Months or More				Total
	Estimated Fair Value		Unrealized Loss			Estimated Fair Value		Unrealized Loss		Estimated Fair Value		Unrealized Loss
June 30, 2011	$	12,995,097	$	(83,117	)	$	—	$	—	$	12,995,097	$	(83,117	)
December 31, 2010	$	7,498,384	$	(96,445	)	$	—	$	—	$	7,498,384	$	(96,445	)

As of June 30, 2011, we did not intend to sell any of these agency securities and we believe it is not more likely than not we will be required to sell the agency securities before recovery of their amortized cost basis. The unrealized losses on these agency securities are not due to credit losses given the government-sponsored entity or government guarantees but are rather due to changes in interest rates and prepayment expectations.

Gains and Losses

The following table is a summary of our net gain from sale of agency securities for the three and six months ended June 30, 2011 and 2010 (in thousands):

	Three Months Ended						Six Months Ended

Net gains on sale of agency securities	$	93,892		$	29,585		$	98,112		$	56,993
Gross gains on sale of agency securities	$	95,684		$	31,327		$	109,233		$	61,381
Gross losses on sale of agency securities		(1,792	)		(1,742	)		(11,121	)		(4,388	)
Net gains on sale of agency securities	$	93,892		$	29,585		$	98,112		$	56,993

(1) Proceeds include cash received during the period, plus receivable for agency securities sold during the period as of period end.

For the three and six months ended June 30, 2011, we recognized an unrealized gain of $0.3 and $3.1 million, and for the three and six months ended June 30, 2010 we recognized an unrealized loss of $9.0 and $8.0 million, respectively, in gain (loss) on derivative instruments and trading securities, net in our consolidated statements of operations and comprehensive income for the change in value of investments in interest-only and principal-only securities. For the three and six months ended June 30, 2011, we recognized a realized gain of $0.5 and $0.5 million in gain on agency securities, respectively, net in our consolidated statements of operations and comprehensive income for the sales of interest-only and principal-only securities. There were no sales of interest-only or principal-only securities during the six months ended June 30, 2010.

Securitizations

All of our CMO securities are backed by fixed or adjustable-rate agency securities and Fannie Mae or Freddie Mac guarantees the payment of interest and principal and acts as the trustee and administrator of their respective securitization trusts. Our involvement with the consolidated CMO trust described below is limited to the agency securities transferred to the trust by the investment bank and the CMO securities subsequently held by us. Accordingly, we are not required to provide the beneficial interest holders of the CMO securities any financial or other support. Whether or not we were involved with the formation of the CMO or purchased the securities from third parties in separate transactions, our maximum exposure to loss related to our involvement with CMO trusts is the fair value of the CMO securities and interest-only securities held by us. As of June 30, 2011 and December 31, 2010, the fair value of all of our CMO securities, interest-only securities and principal-only securities, excluding the consolidated CMO trust discussed below, was $512.1 million and $458.6 million, respectively, or $516.4 million and $463.6 million, respectively, including the net asset value of the consolidated CMO trust discussed below.

During fiscal year 2010, we entered into a CMO transaction whereby we transferred agency securities with a cost basis of $85.9 million to an investment bank in exchange for cash proceeds of $80.8 million and at the same time entered into a commitment with the same investment bank to purchase a to-be-issued interest-only strip collateralized by the agency securities transferred for $5.1 million. The investment bank contributed the transferred agency securities to a securitization trust held by Fannie Mae in exchange for CMO securities issued by the trust. Once the transferred agency securities were transferred to the securitization trust, Fannie Mae may only remove such securities upon certain events. Pursuant to the pre-existing commitment, the investment bank transferred to us the interest-only security issued by the trust. Our primary purpose for entering into this transaction was to eliminate the need to finance the principal class by transferring it to third parties, while still retaining the underlying economics of a financed transaction for the transferred securities, which we viewed as favorable. We concluded that we were the primary beneficiary of the CMO trust based on our disproportionate economic interest and, accordingly, we consolidated the CMO trust as it related to the agency securities transferred by us and the related liabilities issued by the trust. The effect of consolidating the CMO trust was that the interest-only security received was eliminated and we continued to recognize the assets transferred to the securitization trust in our total agency securities held and recorded a corresponding liability for the debt issued by the securitization trust, which is classified as other debt in our accompanying consolidated balance sheets. As of June 30, 2011, we recognized agency securities with a total fair value of $66.1 million and a principal balance of $62.3 million collateralized the remaining debt outstanding issued by the securitization trust of $61.8 million. As of December 31, 2010, we recognized agency securities with a total fair value of $77.9 million and a principal balance of $73.5 million collateralized the remaining debt outstanding issued by the securitization trust of $72.9 million. Such agency securities can only be used to settle this debt and the holder(s) of the debt issued by the

18

securitization trust have no recourse to us. Further, there are no arrangements that could require us to provide financial support to this securitization trust. The consolidation did not materially impact our accompanying consolidated statements of operations and comprehensive income and consolidated statements of cash flows.

Note 5. Repurchase Agreements and Other Debt

We pledge certain of our agency securities as collateral under repurchase arrangements with financial institutions, the terms and conditions of which are negotiated on a transaction-by-transaction basis. Interest rates on these borrowings are generally based on LIBOR plus or minus a margin and amounts available to be borrowed are dependent upon the fair value of the agency securities pledged as collateral, which fluctuates with changes in interest rates, type of security and liquidity conditions within the banking, mortgage finance and real estate industries. In response to declines in fair value of pledged agency securities, lenders may require us to post additional collateral or pay down borrowings to re-establish agreed upon collateral requirements, referred to as margin calls. As of June 30, 2011 and December 31, 2010, we have met all margin call requirements. Due to their short-term nature, repurchase agreements are carried at cost, which approximates fair value.

The following table summarizes our borrowings under repurchase arrangements and weighted average interest rates classified by original maturities as of June 30, 2011 and December 31, 2010 (dollars in thousands):

	As of June 30, 2011							As of December 31, 2010

Total / Weighted Average	$	33,505,142		0.23	%		20	$	11,680,092		0.31	%		22

As of June 30, 2011 and December 31, 2010, we did not have an amount at risk with any counterparty greater than 10% of our stockholders’ equity. We do not anticipate any defaults by our repurchase agreement counterparties.

Other debt of $61.8 million and $72.9 million as of June 30, 2011 and December 31, 2010, respectively, consists of other variable rate debt outstanding at LIBOR plus 25 basis points in connection with the consolidation of a structured transaction for which we are the primary beneficiary in our accompanying financial statements (see Note 4).

Note 6. Derivative and Other Hedging Instruments

In connection with our risk management strategy, we hedge a portion of our interest rate risk by entering into derivative and other hedging instrument contracts. We may enter into agreements for interest rate swap agreements, interest rate swaptions, interest rate cap or floor contracts and futures or forward contracts. We may also purchase or short TBA and U.S. Treasury securities, purchase or write put or call options on TBA securities or we may invest in other types of mortgage derivative securities, such as interest-only securities, and synthetic total return swaps, such as the IOS Index. Our risk management strategy attempts to manage the overall risk of the portfolio, reduce fluctuations in book value and generate additional income distributable to stockholders. For additional information regarding our derivative instruments and our overall risk management strategy, please refer to the discussion of derivative and other hedging instruments in Note 3.

As of June 30, 2011 and December 31, 2010, our derivative and other hedging instruments were comprised primarily of interest rate swaps, which have the effect of modifying the repricing characteristics of our repurchase agreements and cash flows on such liabilities. Our interest rate swaps are used to manage the interest

19

rate risk created by our variable rate short-term repurchase agreements. Under our interest rate swaps, we typically pay a fixed-rate and receive a floating rate based on one-month LIBOR with terms usually ranging up to 5 years. Our interest rate swaps are generally designated as cash flow hedges under ASC 815.

Derivative and other hedging instruments entered into in addition to interest rate swap agreements are intended to supplement our use of interest rate swaps and we do not currently expect our use of these instruments to be the primary protection against interest rate risk for our portfolio. These instruments are accounted for as either derivatives, but are not typically designated as hedges under ASC 815, or trading securities. Therefore, any changes in the fair values of the contracts prior to their settlement date are included in earnings. We do not use derivative or other hedging instruments for speculative purposes.

Derivatives Designated as Hedging Instruments

As of June 30, 2011 and December 31, 2010, we had net interest rate swap liabilities of $233.1 million and $37.7 million, respectively. The tables below summarize information about our outstanding interest rate swaps as of June 30, 2011 and December 31, 2010 (dollars in thousands):

Additionally, during the six months ended June 30, 2011 and the three and six months ended June 30, 2010, we entered into or held forward contracts to purchase TBA and specified agency securities that were designated as cash flow hedges pursuant to ASC 815. We did not enter into such agreements during the three month period ended June 30, 2011. The following table summarizes information about our outstanding forward contracts designated as hedging instruments for the three and six months ended June 30, 2011 and 2010 (dollars in thousands):

As of June 30, 2011, we had total return swaps outstanding linked to the Markit IOS Index, summarized in the table below. Under these swap agreements, we are either entitled to receive (“long position”) or pay (“short position”) a stated coupon linked to the index, net of an implied financing cost equal to one-month LIBOR, plus/(minus) increases/(decreases) in the index market value. Long positions are intended to synthetically replicate the performance of interest-only securities. Therefore, as interest rates rise and prepayment expectations decline, the index will typically increase in value and, as interest rates fall and prepayment expectations rise, the index will typically decrease in value. As the holder of the long position, we are required to pay a monthly periodic cash settlement equal to a decrease in the index value and, conversely, we are entitled to receive a periodic cash settlement equal to an increase in the index value. Changes, or mark-to-market movements, in the index are measured from the preceding periodic measurement date. Periodic cash settlements of the index mark-to-market movements are netted against periodic cash settlements of the stated coupon, less the implied financing costs. As of June 30, 2011, the linked index values of our total return swaps totaled $75.7 million. As of June 30, 2011, the fair value of these total return swaps reported in derivative assets, at fair value on our consolidated balance sheet was $0.1 million and represents the unrealized mark-to-market change in the linked index value since the preceding measurement date through June 30, 2011. Realized and unrealized gains and losses associated with changes in the underlying linked index value and net coupon interest are recognized in gain (loss) on derivative instruments and trading securities, net in our consolidated statements of operations and comprehensive income. We did not have any total return swaps outstanding as of December 31, 2010.

Credit Risk-Related Contingent Features

The use of derivatives creates exposure to credit risk relating to potential losses that could be recognized in the event that the counterparties to these instruments fail to perform their obligations under the contracts. We minimize this risk by limiting our counterparties to major financial institutions with acceptable credit ratings and monitoring positions with individual counterparties. In addition, we may be required to pledge assets as collateral for our derivatives, whose amounts vary over time based on the market value, notional amount and remaining

27

term of the derivative contract. In the event of a default by a counterparty we may not receive payments provided for under the terms of our derivative agreements, and may have difficulty obtaining our assets pledged as collateral for our derivatives. The cash and cash equivalents and agency securities pledged as collateral for our derivative instruments is included in restricted cash and agency securities, respectively, on our consolidated balance sheets.

Each of our ISDA Master Agreements contains provisions under which we are required to fully collateralize our obligations under the swap instrument if at any point the fair value of the swap represents a liability greater than the minimum transfer amount contained within our agreements. We were also required to post initial collateral upon execution of certain of our swap transactions. If we breach any of these provisions, we will be required to settle our obligations under the agreements at their termination values.

Further, each of our ISDA Master Agreements also contains a cross default provision under which a default under certain of our other indebtedness in excess of a certain threshold causes an event of default under the agreement. Threshold amounts vary by lender. Following an event of default, we could be required to settle our obligations under the agreements at their termination values. Additionally, under certain of our ISDA Master Agreements, we could be required to settle our obligations under the agreements at their termination values if we fail to maintain certain minimum shareholders’ equity thresholds or our REIT status or comply with limits on our leverage above certain specified levels.

As of June 30, 2011, the fair value of our interest rate swaps in a liability position related to these agreements was $265.4 million. We had agency securities with fair values of $293.7 million, and restricted cash of $188.8 million, or $482.5 million in total agency securities and restricted cash, pledged as collateral against our interest rate swaps, including initial collateral posted upon execution of interest rate swap and total return swap transactions, as of June 30, 2011. Termination values of interest rate swaps in a liability position totaled $271.2 million as of June 30, 2011. The difference between the fair value liability and the termination liability represents accrued interest and an adjustment for nonperformance risk of our counterparties.

Note 7. Fair Value Measurements

ASC 820 provides for a three-level valuation hierarchy for disclosure of fair value measurement. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There were no transfers between hierarchy levels during the six months ended June 30, 2011 and 2010. The three levels of hierarchy are defined as follows:

• Level 1 Inputs —Quoted prices (unadjusted) for identical unrestricted assets and liabilities in active markets that are accessible at the measurement date.

• Level 2 Inputs —Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

• Level 3 Inputs —Instruments with primarily unobservable market data that cannot be corroborated.

All of our agency securities and derivative and hedging assets and liabilities were valued based on the income or market approach using Level 2 inputs as of June 30, 2011 and December 31, 2010.

Controlled Equity Offering^SM Program

We have a sales agreement with an underwriter to, from time to time, publicly offer and sell up to 15 million shares of our common stock in privately negotiated and/or at-the-market transactions. During the three month period ended June 30, 2011, there were no sales under the sales agreement. During the six month period ended June 30, 2011, we sold 4.3 million shares of our common stock under the sales agreement at an average offering price of $29.41 per share for proceeds, net of the underwriter’s discount and other program costs, of $126.1 million. As of June 30, 2011, 6.3 million shares of our common stock remain under the sales agreement.

Dividend Reinvestment and Direct Stock Purchase Plan

We sponsor a dividend reinvestment and direct stock purchase plan through which stockholders may purchase additional shares of our common stock by reinvesting some or all of the cash dividends received on shares of our common stock. Stockholders may also make optional cash purchases of shares of our common stock subject to certain limitations detailed in the plan prospectus. During the three month period ended June 30, 2011, there were no shares issued under the plan. During the six month period ended June 30, 2011, we issued 0.5 million shares under the plan for net cash proceeds of $14.9 million. As of June 30, 2011, there were 4.7 million shares available for issuance under the plan.

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

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is designed to provide a reader of American Capital Agency Corp.’s consolidated financial statements with a narrative from the perspective of management. Our MD&A is presented in five sections:

• Executive Overview

• Financial Condition

• Results of Operations

• Liquidity and Capital Resources

• Forward-Looking Statements

EXECUTIVE OVERVIEW

American Capital Agency Corp. (“AGNC”, the “Company”, “we”, “us” and “our”) was organized on January 7, 2008 and commenced operations on May 20, 2008 following the completion of our initial public offering (“IPO”). Our common stock is traded on The NASDAQ Global Select Market under the symbol “AGNC”.

We earn income primarily from investing in residential mortgage pass-through securities and collateralized mortgage obligations (“CMOs”) on a leveraged basis. These investments consist of securities for which the principal and interest payments are guaranteed by U.S. Government-sponsored entities (“GSEs”), such as the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), or by a U.S. Government agency, such as the Government National Mortgage Association, (“Ginnie Mae”). We refer to these types of securities as agency securities and the specific agency securities in which we invest as our investment portfolio.

Our principal objective is to preserve our net asset value while generating attractive risk-adjusted returns for distribution to our stockholders through regular quarterly dividends from our net interest income, which is the spread between the interest income earned on our interest earning assets and the interest costs of our borrowings and hedging activities, and net realized gains and losses on our investments and other supplemental hedging activities. We fund our investments primarily through short-term borrowings structured as repurchase agreements.

We have elected to be taxed as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended (the “Code”). As such, we are required to distribute annually 90% of our taxable net income. As long as we qualify as a REIT, we will generally not be subject to U.S. federal or state corporate taxes on our taxable net income to the extent that we distribute all of our annual taxable net income to our stockholders. We are externally managed by American Capital AGNC Management, LLC (“our Manager”), an affiliate of American Capital, Ltd. (“American Capital”).

Our Investment Strategy

Our investment strategy is to manage an investment portfolio consisting exclusively of agency securities (other than for hedging purposes) that seeks to generate attractive, risk-adjusted returns. Specifically, our investment strategy is designed to:

• manage an investment portfolio consisting of agency securities that seeks to generate attractive risk-adjusted returns;

• capitalize on discrepancies in the relative valuations in the agency securities market;

• manage financing, interest and prepayment rate risks;

• preserve our net asset value;

30

• provide regular quarterly distributions to our stockholders;

• qualify as a REIT; and

• remain exempt from the requirements of the Investment Company Act of 1940, as amended (the “Investment Company Act”).

FINANCIAL CONDITION

As of June 30, 2011 and December 31, 2010, our investment portfolio consisted of $39.9 billion and $13.5 billion, respectively, of agency securities. The following tables summarize certain characteristics of our investment portfolio as of June 30, 2011 (dollars in thousands):

Actual maturities of agency securities are generally shorter than stated contractual maturities primarily as a result of prepayments of principal of the underlying mortgages. The stated contractual final maturity of the mortgage loans underlying our portfolio of agency securities ranges up to 40 years, but the expected maturity is subject to change based on the actual and expected future prepayments of the underlying loans. As of June 30, 2011 and December 31, 2010, the average final contractual maturity of the agency securities in our investment portfolio was 21 and 22 years, respectively. The estimated weighted average months to maturity of the agency securities in the table below are based upon our prepayment expectations, which are estimated based on assumptions for different securities using a combination of third-party services, market data and internal models. The third-party services estimate prepayment speeds using models that incorporate the forward yield curve, mortgage rates, current mortgage rates of the outstanding loans, loan age, volatility and other factors. As market conditions are changing rapidly, we use judgment in making adjustments to our models for some products. Various market participants could use materially different assumptions.

The following table summarizes our agency securities classified as available-for-sale, at fair value, according to their estimated weighted average life classifications as of June 30, 2011 and December 31, 2010 (in thousands):

	As of June 30, 2011							As of December 31, 2010
Weighted Average Life	Fair Value		Amortized Cost		Weighted Average Coupon			Fair Value			Amortized Cost		Weighted Average Coupon

The weighted average life of our interest-only and principal-only securities was 5.2 and 6.2 years as of June 30, 2011 and December 31, 2010, respectively.

The constant prepayment rate (“CPR”) reflects the percentage of principal that is prepaid over a period of time on an annualized basis. In general, while there are various factors that impact the rate of prepayments, as interest rates rise, the rate of refinancings typically declines, which may result in lower rates of prepayment and, as a result, a lower portfolio CPR. Conversely, as interest rates fall, the rate of refinancings typically increases, which may result in higher rates of prepayment and, as a result, a higher portfolio CPR. As of June 30, 2011, our portfolio was purchased at a net premium.

In determining the estimated weighted average months to maturity of our agency securities and the yield on our agency securities, we have assumed that the CPR over the remaining projected life of our aggregate investment portfolio is 10% as of June 30, 2011. We make different prepayment assumptions for the individual securities that comprise the investment portfolio and these individual assumptions can differ materially from the average. There is also considerable uncertainty around prepayment speeds in this environment and actual speeds could differ materially from our estimates. Furthermore, GSE buyouts of loans in imminent risk of default, loans that have been modified, or loans that have defaulted will generally be reflected as prepayments on agency securities and also increase the uncertainty around these estimates. In addition, securities were purchased with different amounts of premiums and therefore the yield on some securities is more sensitive to changes in prepayment speeds.

* Average numbers for each period are weighted based on days on our books and records, all percentages are annualized.

(1) Net asset value per common share was calculated by dividing our total stockholders’ equity by our number of shares outstanding.

(2) Average repurchase agreement and other debt represents their daily weighted average balances, less amounts used to fund short-term investments in U.S. treasury securities.

(3) Average stockholders’ equity calculated as the average month-end stockholders’ equity balance outstanding during the period.

(4) Weighted average coupon for the period was calculated by dividing our total coupon (or cash) interest income on our agency securities by our daily weighted average agency securities.

(5) Weighted average asset yield for the period was calculated by dividing our total interest income on our agency securities, including amortization of premiums and discounts, by our daily weighted average agency securities.

(6) Weighted average cost of funds for the period was calculated by dividing our total interest expense by our daily weighted average repurchase agreements and other debt. Total interest expense excludes amortization expense related to the costs of the previously terminated interest rate swaps during the periods presented.

(7) Represents amortization expense associated with interest rate swaps terminated in a prior period of $2.6 million and $6.3 million for the three and six months ended June 30, 2010, respectively,

(8) Average net interest rate spread for the period was calculated by subtracting our weighted average cost of funds, net of interest rate swaps and terminated swap amortization expense, from our weighted average asset yield.

(9) Leverage during the period was calculated by dividing the our daily weighted average repurchase agreements and other debt outstanding, less repurchase agreements for treasury securities, for the period by our average month-ended stockholders’ equity for the period. Average leverage for the three month period ended June 30, 2011 was 8.3x,pro forma, when average equity is adjusted to exclude the June 2011 follow-on equity offering that closed on June 28, 2011.

(10) Leverage at period end was calculated by dividing the sum of the amount outstanding under our repurchase

agreements, net receivable/payable for unsettled agency securities and other debt by our total stockholders’ equity at period end.

(11) Annualized expenses as a percentage of average total assets was calculated by dividing our total expenses by our average total assets on an annualized basis.

(12) Annualized expenses as a percentage of average stockholders’ equity was calculated by dividing our total expenses by our average stockholders’ equity on an annualized basis.

(13) Annualized net return on average stockholders’ equity for the period was calculated by dividing our net income by our average stockholders’ equity on an annualized basis.

(14) Annualized economic return represents the sum of the change in net asset value over the period and dividends declared during the period over the beginning net asset value on an annualized basis.

Interest Income and Asset Yield

Interest income was $264.7 million and $50.6 million for the three months ended June 30, 2011 and 2010, respectively. Interest income was $429.2 million and $89.4 million for the six months ended June 30, 2011 and 2010, respectively. The year-over-year increases were due to an increase in our average investment portfolio, partially offset by a decline in our average asset yield.

Our average asset yield declined to 3.35% for the current three month period from 3.44% for the prior year three month period and to 3.37% for the current six month period from 3.58% for the prior year six month period as a result of acquiring lower yielding securities due to changes in portfolio composition. The average coupon of our investment portfolio declined to 4.55% for each of the current year periods from approximately 5.20% for the prior year periods, while the average amortized cost basis of our investment portfolio remained largely unchanged at 104.4% of par value for each of the current year periods compared to approximately 104.1% of par value for the prior year periods.

We amortize premiums and discounts associated with agency securities into interest income over the life of such securities using the effective yield method. The effective yield (or asset yield) on our agency securities is based on actual CPRs realized for individual securities in our investment portfolio through the reporting date and assumes a CPR over the remaining projected life of our aggregate investment portfolio of 10% and 20% as of June 30, 2011 and 2010, respectively. The actual CPR realized for individual securities in our investment portfolio was approximately 9% and 28% for the current and prior year three month periods, respectively, and 10% and 24% for the current and prior year six month periods, respectively. The year-over-year decrease in the actual CPR realized is due to the impact of buyouts of accumulated delinquent loans by the GSEs from mortgage pools collateralizing agency securities (“GSE Buyouts”) during the first half of 2010, which had the impact of increasing the average prepayment speed of our portfolio during the prior year period. The decrease in the forecasted CPR is primarily due a higher percentage of securities held that are collateralized by loans with favorable prepayment attributes as of June 30, 2011 relative to the prior period.

Additionally, pursuant to ASC 310-20, the yield on our adjustable rate securities assumes that the securities reset at a rate equal to the underlying index rate in effect as of the date we acquired the security plus the stated margin. Consequently, future reset rate assumptions incorporated in our asset yields may differ materially from future reset rates implied by the forward yield curve and the actual reset rates ultimately achieved. Further, notwithstanding changes to our actual and projected CPR assumptions, the lower our reset rate assumption is pursuant to ASC 310-20 than the current fixed rate in effect, the greater the rate of premium amortization we will recognize over the initial fixed rate period. Our adjustable rate portfolio was acquired for a premium above par value and most securities were acquired during a period of historically low index rates. Accordingly, the majority of the premium balance on our adjustable rate securities will be amortized prior to their first reset date, regardless of actual or forecasted prepayment speeds and changes in the underlying index rates prior to actual reset. Adjustable rate securities acquired during a different interest rate environment may experience a different premium amortization pattern even as current index rates remain near their historical lows. For adjustable rate securities held as of June 30, 2011, the weighted average coupon rate was 4.18%, the weighted average months to reset was 74 months and the weighted average reset rate assumption was 2.72%, which is based on a weighted average underlying index rate of 0.91% as of the date we acquired the securities and a weighted average margin of 1.81%.

37

Interest income for the current and prior year three month period is net of $78.9 million and $22.9 million, respectively, and for the current and prior year six month period is net of $126.9 million and $35.2 million, respectively, for net amortization of premiums and discounts on our investment portfolio. The unamortized premium balance of our aggregate investment portfolio, including the unamortized cost basis of our interest-only securities and net of discounts, was $1.7 billion and $626.3 million as of June 30, 2011 and December 31, 2010, respectively.

Leverage

Our leverage as of June 30, 2011 and December 31, 2010 was 7.0 and 7.5 times our stockholders’ equity, respectively. When adjusted for the net payable for agency securities purchased but not yet settled, our leverage ratio was 7.5 and 7.8 times our stockholders’ equity as of June 30, 2011 and December 31, 2010, respectively. Our actual leverage will vary from time to time based on various factors, including our Manager’s opinion of the level of risk of our assets and liabilities, our liquidity position, our level of unused borrowing capacity, over-collateralization levels required by lenders when we pledge agency securities to secure our borrowings and the current market value of our investment portfolio. In addition, certain of our master repurchase agreements and master swap agreements contain a restriction that prohibits our leverage from exceeding certain levels.

The table below presents our quarterly average and quarter end repurchase agreement and other debt balances outstanding and average leverage ratios for the three and six months ended June 30, 2011 and 2010 and December 31, 2010 (dollars in thousands):

(1) Average leverage for the period was calculated by dividing our daily weighted average repurchase agreements and other debt outstanding, less repurchase agreements for treasury securities, by the Company’s average month-ended stockholders’ equity for the period.

(2) Leverage as of period end was calculated by dividing the amount outstanding under our repurchase agreements and other debt by our stockholders’ equity at period end.

(3) Leverage as of period end, net of unsettled trades was calculated by dividing the sum of the amount outstanding under our repurchase agreements, net liabilities and receivables for unsettled agency securities and other debt by our total stockholders’ equity at period end.

(4) Average leverage for the three months ended March 31 and June 30, 2011 was 8.2x and 8.3x,pro forma, when average equity is adjusted to exclude the March and June 2011 follow-on equity offering that closed on March 25 and June 28, 2011, respectively.

(5) Average leverage for the period was higher than leverage as of period end because we had not fully invested net proceeds raised from follow-on equity offerings occurring late in the period.

Interest Expense and Cost of Funds

Interest expense was $63.8 million and $17.3 million for the three months ended June 30, 2011 and 2010, respectively. Interest expense was $99.5 million and $32.9 million for the six months ended June 30, 2011 and 2010, respectively. The year-over-year increase in interest expense was due to an increase in our average repurchase agreement and other debt balance outstanding, partially offset by a decline in swap interest expense due to timing differences between asset settlements and the initiation of new interest rate swap agreements and a reduction of swap interest expense of $2.6 million and $6.3 million for terminated swap amortization expense recorded during the three and six month prior year periods, respectively.

For the three month period ended June 30, 2011 and 2010, our average repurchase agreement and other debt balance outstanding was $28.7 billion and $5.5 billion, respectively. For the six month period ended June 30, 2011 and 2010, our average repurchase agreement and other debt balance outstanding was $23.2 billion and $4.7 billion, respectively. The year-over-year increases were primarily driven by deploying new equity capital raised during the current periods on a levered basis. The average interest rate on our repurchase agreements and other debt remained unchanged for the three and six month periods ended June 30, 2011 and 2010 at approximately 0.25%. Including the net impact of interest rate swaps, the total three and six month average cost of funds declined year-over-year to 0.89% from 1.26% (or from 1.07% when excluding amortization expense associated with previously terminated interest rate swaps), respectively, and to 0.86% from 1.42% (or from 1.15% when excluding amortization expense associated with previously terminated interest rate swaps), respectively.

For the current and prior year three month period, our interest rate swaps designated as cash flow hedges under ASC 815 increased the cost of our borrowings by $46.3 million and $11.2 million, or 0.65% and 0.81% of our interest bearing liabilities, respectively. When excluding forward starting swaps, for the current and prior year three month period, we had average notional amounts outstanding under our interest rate swap agreements designated as cash flow hedges of $12.0 billion and $2.6 billion (or 42% and 46% of our average repurchase agreement and other debt balance) with a weighted average fixed pay rate of 1.72% and 2.01%, respectively. For the current and prior year six month period, our interest rate swaps designated as cash flow hedges increased the cost of our borrowings by $69.5 million and $21.0 million, or 0.60% and 0.91% of our interest bearing liabilities, respectively. When excluding forward starting swaps, for the current and prior year six month period, we had average notional amounts outstanding under our interest rate swap agreements designated as cash flow hedges of $9.3 billion and $2.4 billion (or 40% and 51% of our average repurchase agreement and other debt balance) with a weighted average fixed pay rate of 1.69% and 2.0%, respectively.

Net Interest Income and Net Interest Rate Spread

Net interest income, which equals interest income less interest expense, was $200.9 million and $33.2 million for the three month period ended June 30, 2011 and 2010, respectively. The average net interest rate spread, which equals the average yield on our assets for the period less the average cost of funds for the three month period ended June 30, 2011 and 2010, was 2.46% and 2.18% (or 2.37% excluding terminated swap amortization expense), respectively. Net interest income was $329.8 million and $56.5 million for the six month period ended June 30, 2011 and 2010, respectively. The average net interest rate spread for the six month period ended June 30, 2011 and 2010, was 2.51% and 2.16% (or 2.43% excluding terminated swap amortization expense), respectively. As of June 30, 2011, our weighted average asset yield was 3.45%, our weighted average cost of funds was 1.09% and our net interest rate spread was 2.36%.

Our weighted average cost of funds as of June 30, 2011 is based on our total repurchase agreement and other debt balance outstanding, plus the net payable for unsettled trades, (altogether totaling $35.7 billion), a weighted average interest rate on our repurchase agreements of 0.23%, and an interest rate swap balance of $21.0 billion notional and an average pay rate of 1.64% (or 1.45% net of the receive rate). The interest rate swap balance includes interest rate swaps designated as cash flow hedges in effect as of June 30, 2011 totaling $14.1 billion, plus $6.9 billion of forward starting swaps, net of interest rate expirations, starting within three months of June 30, 2011.

39

As of June 30, 2011, we had a total of $7.9 billion of forward starting interest rate swaps with forward start dates ranging from one to six months from June 30, 2011. We enter into forward starting interest rate swaps based on a variety of factors, including our Manager’s view of the forward yield curve and the timing of potential changes in short-term interest rates, time to deploy new capital, amount and timing of expirations of our existing interest swap portfolio and current and anticipated swap spreads.

(1) Proceeds include cash received during the period, plus receivable for agency securities sold during the period as of period end.

Sales of securities are driven by our Manager’s execution of our active portfolio management strategy. Our strategy for the periods presented was largely focused on repositioning our portfolio towards securities with attributes our Manager believes reduce the level of prepayment risk and overall exposure to interest rate risk in light of current and anticipated interest rates, federal government programs, general economic conditions and other factors. During the three month period ended June 30, 2011, we sold holdings of higher coupon securities and reinvested the sales’ proceeds into lower coupon, shorter duration securities backed by loans our Manager believes have more favorable prepayment attributes relative to the current economic environment, including the general decline in interest rates as of the end of the current period. Sales of securities during the prior year periods were similarly driven by Manager’s intent of reinvesting sales proceeds into assets with more favorable involuntary prepayment attributes in anticipation of the GSE Buyouts of built up delinquent mortgage loans from their outstanding mortgage pools during the prior year periods.

(1) Unrealized gain (loss) from derivatives and trading securities includes reversals of prior period amounts for settled or expired derivatives and trading securities.

The year over year increases in net losses from derivatives and trading securities (“other supplemental hedges”) were due to an increase in the size of our investment portfolio coupled with an increase in our use of other supplemental hedging strategies entered into to manage the potential adverse impact of near term changes in interest rates on our net asset value and future cash flows. We invest in other supplemental hedges, in addition to our use of interest rate swap agreements that are intended to hedge against longer-term increases in interest rates, based on a variety of factors, including our Manager’s view of how our existing portfolio of agency securities will perform under different interest rate scenarios and the need to hedge against potential near-term changes in interest rates. The intended purpose of the other supplemental hedges held during the current three month period was to hedge against potential near-term increases in interest rates, consequently the net losses from our supplemental hedges for the current three month period were driven by a general decline in interest rates during the period.

Management Fees and General and Administrative Expenses

We pay our Manager a base management fee payable monthly in arrears in amount equal to one twelfth of 1.25% of our Equity. Our Equity is defined as our month-end stockholders’ equity, adjusted to exclude the effect of any unrealized gains or losses included in either retained earnings or OCI, each as computed in accordance with GAAP. There is no incentive compensation payable to our Manager pursuant to the management agreement. We incurred management fees of $12.4 million and $2.3 million for the three month periods ended June 30, 2011 and 2010, respectively, and $20.9 million and $4.1 million for the six month periods ended June 30, 2011 and 2010, respectively.

General and administrative expenses were $4.5 million and $1.8 million for the three month periods ended June 30, 2011 and 2010, respectively, and $7.1 million and $3.5 million for the six month periods ended June 30, 2011 and 2010, respectively. Our general and administrative expenses primarily consist of prime brokerage fees, information technology costs, allocation of overhead expenses from our Manager, accounting fees, legal fees, Board of Director fees and insurance expenses.

Our total management fee and general and administrative expenses as a percentage of our average stockholders’ equity on an annualized basis declined year-over-year to 1.80% from 2.33% for the current and prior three month period, respectively, and to 1.82% from 2.37% for the current and prior six month period, respectively, due to improved operating leverage.

Dividends

For the current and prior year periods, we declared quarterly dividends of $1.40 per share. As a REIT, we are required to distribute annually 90% of our taxable income to maintain our status as a REIT and all of our taxable income to avoid Federal, state and local corporate income taxes. We can treat dividends declared by September 15 and paid by December 31 as having been a distribution of our taxable income for our prior tax year. As of June 30, 2011, we have declared or paid all of our taxable income for the 2010 tax year and we have an estimated $78 million of undistributed taxable income related to our 2011 tax year, net of the June 30, 2011 dividend payable of $180.4 million. Income as determined under GAAP differs from income as determined under tax rules because of both temporary and permanent differences in income and expense recognition. Examples include temporary differences related to unrealized gains and losses on derivative instruments and trading securities that are recognized in income for GAAP but are excluded from taxable income until realized or settled, temporary differences in the CPR used to amortize premiums or accrete discounts, temporary differences related to timing of the recognition of hedge ineffectiveness, permanent and temporary differences related to the timing and amount recognized for stock-based compensation and permanent differences for excise tax expense.

LIQUIDITY AND CAPITAL RESOURCES

Our primary sources of funds are borrowings under master repurchase agreements, equity offerings, asset sales and monthly principal and interest payments on our investment portfolio. Because the level of our borrowings can be adjusted on a daily basis, the level of cash and cash equivalents carried on the balance sheet is significantly less important than the potential liquidity available under our borrowing arrangements. We currently believe that we have sufficient liquidity and capital resources available for the acquisition of additional investments, repayments on borrowings, maintenance of any margin requirements and the payment of cash dividends as required for our continued qualification as a REIT. To qualify as a REIT, we must distribute annually at least 90% of our taxable income. To the extent that we annually distribute all of our taxable income in a timely manner, we will generally not be subject to federal and state income taxes. We currently expect to distribute all of our taxable income. This distribution requirement limits our ability to retain earnings and thereby replenish or increase capital from operations.

42

Equity Capital Raising Activities

To the extent we raise additional equity capital through follow-on equity offerings, through our Controlled Equity Offering^SM program or under our dividend reinvestment and direct stock purchase plan, we currently anticipate using cash proceeds from such transactions to purchase additional agency securities, to make scheduled payments of principal and interest on our repurchase agreements and for other general corporate purposes. There can be no assurance, however, that we will be able to raise additional equity capital at any particular time or on any particular terms.

Equity Offerings

During the six months ended June 30, 2011, we completed three follow-on public offerings of shares of our common stock summarized in the table below (in thousands, except per share amounts):

	For the Six Months Ended June 30, 2011
Public Offering	Public Offering Price Per Share(1)		Shares		Net Proceeds(2)
January 2011	$	28.00		26,910	$	719,250
March 2011	$	27.72		32,200		892,242
June 2011	$	27.56		49,680		1,368,756
Total				108,790	$	2,980,248

(1) Public offering price per share is gross of underwriters’ discount, if applicable

(2) Proceeds received, net of the underwriters’ discount, if applicable, and other offering costs

Controlled Equity Offering^SM Program

We have a sales agreement with an underwriter to, from time to time, publicly offer and sell up to 15 million shares of our common stock in privately negotiated and/or at-the-market transactions. During the three month period ended June 30, 2011 there were no sales under the sales agreement. During the six month period ended June 30, 2011, we sold 4.3 million shares of our common stock under the sales agreement at an average offering price of $29.41 per share for proceeds, net of the underwriter’s discount and other program costs, of $126.1 million. As of June 30, 2011, 6.3 million shares of common stock remain under the sales agreement.

Dividend Reinvestment and Direct Stock Purchase Plan

We sponsor a dividend reinvestment and direct stock purchase plan through which stockholders may purchase additional shares of our common stock by reinvesting some or all of the cash dividends received on shares of our common stock. Stockholders may also make optional cash purchases of shares of our common stock subject to certain limitations detailed in the plan prospectus. During the three month period ended June 30, 2011 there were no shares issued under the plan. During the six month period ended June 30, 2011, we issued 0.5 million shares under the plan for net cash proceeds of $14.9 million. As of June 30, 2011, there were 4.7 million shares available for issuance under the plan.

Debt Capital

As part of our investment strategy, we borrow against our investment portfolio pursuant to master repurchase agreements. We expect that our borrowings pursuant to repurchase transactions under such master repurchase agreements generally will have maturities that range from 30 to 90 days, but may have maturities of less than 30 days or up to 364 days. When adjusted for net payables and receivables for agency securities purchased but not yet settled and other debt, our leverage ratio was 7.5 times the amount of our stockholders’

43

equity as of June 30, 2011. Our cost of borrowings under master repurchase agreements generally corresponds to LIBOR plus or minus a margin. We have master repurchase agreements with 26 financial institutions, subject to certain conditions. As of June 30, 2011, borrowings under repurchase arrangements secured by agency securities totaled $33.5 billion, other debt associated with a structured transaction accounted for as a financing transaction totaled $0.1 billion and net payables for agency securities not yet settled was $2.1 billion. As of June 30, 2011, we did not have an amount at risk with any counterparty greater than 10% of our stockholders’ equity. Refer to Note 5 to our consolidated financial statements in this Quarterly Report on Form 10-Q for further details regarding our borrowings under repurchase agreements and other debt and weighted average interest rates as of June 30, 2011.

Amounts available to be borrowed under our repurchase agreements are dependent upon lender collateral requirements and the lender’s determination of the fair value of the securities pledged as collateral, which fluctuates with changes in interest rates, credit quality and liquidity conditions within the investment banking, mortgage finance and real estate industries. Under the repurchase agreements, we may be required to pledge additional assets to the repurchase agreement counterparties (i.e., lenders) in the event the estimated fair value of the existing pledged collateral under such agreements declines and such lenders demand additional collateral (a margin call), which may take the form of additional securities or cash. Similarly, if the estimated fair value of investment securities increases due to changes in the market interest rates, lenders may release collateral back to us. Specifically, margin calls would result from a decline in the value of the agency securities securing our repurchase agreements and prepayments on the mortgages securing such agency securities. As of June 30, 2011, we have met all margin requirements. We had unrestricted cash and cash equivalents of $625.9 million and unpledged agency securities of $2.1 billion, excluding net unsettled purchases and sales of agency securities, available to meet margin calls on our repurchase agreements and derivative instruments as of June 30, 2011.

Although we believe that we will have adequate sources of liquidity available to us through repurchase agreement financing to execute our business strategy, there can be no assurances that repurchase agreement financing will be available to us upon the maturity of our current repurchase agreements to allow us to renew or replace our repurchase agreement financing on favorable terms or at all. If our repurchase agreement lenders default on their obligations to resell the underlying agency securities back to us at the end of the term, we could incur a loss equal to the difference between the value of the agency securities and the cash we originally received.

We maintain an interest rate risk management strategy under which we use derivative financial instruments to manage the adverse impact of interest rates changes on the value of our investment portfolio as well as our cash flows. In particular, we attempt to mitigate the risk of the cost of our short-term variable rate liabilities increasing at a faster rate than the earnings of our long-term assets during a period of rising interest rates. The principal derivative instruments that we use are interest rate swaps, supplemented with the use of interest rate swaptions, TBA agency securities, options, futures and other instruments.

We use interest rate swap agreements to effectively lock in fixed rates on a portion of our short-term borrowings because longer-term committed borrowings are not available at attractive terms. We have entered into interest rate swap agreements to attempt to mitigate the risk of the cost of our short-term variable rate liabilities rising during a period of rising interest rates, thereby compressing the net spreads that we earn on our long-term fixed-rate assets. As of June 30, 2011, we had interest rate swap agreements that were designated as cash flow hedges for accounting purposes of a like amount of our short-term borrowings. Refer to Note 6 to our consolidated financial statements in this Quarterly Report on Form 10-Q for further details regarding our outstanding interest rate swaps as of June 30, 2011 and the related activity for the first quarter 2011.

Off-Balance Sheet Arrangements

As of June 30, 2011, we did not maintain any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance, or special purpose or variable interest

44

entities, established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Further, as of June 30, 2011, we had not guaranteed any obligations of unconsolidated entities or entered into any commitment or intent to provide funding to any such entities.

FORWARD-LOOKING STATEMENTS

This document contains “forward-looking statements” (within the meaning of the Private Securities Litigation Reform Act of 1995) that inherently involve risks and uncertainties. Our actual results and liquidity can differ materially from those anticipated in these forward-looking statements because of changes in the level and composition of our investments and other factors. These factors may include, but are not limited to, changes in general economic conditions, the availability of suitable investments from both an investment return and regulatory perspective, the availability of new investment capital, fluctuations in interest rates and levels of mortgage prepayments, deterioration in credit quality and ratings, the effectiveness of risk management strategies, the impact of leverage, liquidity of secondary markets and credit markets, increases in costs and other general competitive factors.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the exposure to loss resulting from changes in interest rates, foreign currency exchange rates, commodity prices and equity prices. The primary market risks that we are exposed to are interest rate risk, prepayment risk, spread risk, liquidity risk, extension risk and inflation risk.

Interest Rate Risk

Interest rate risk is highly sensitive to many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors beyond our control.

Changes in the general level of interest rates can affect our net interest income, which is the difference between the interest income earned on interest-earning assets and the interest expense incurred in connection with our interest-bearing liabilities, by affecting the spread between our interest-earning assets and interest bearing liabilities. Changes in the level of interest rates can also affect the rate of prepayments of our securities and the value of the agency securities that constitute our investment portfolio, which affects our ability to realize gains from the sale of these assets and impacts our ability and the amount that we can borrow against these securities.

We may utilize a variety of financial instruments in order to limit the effects of changes in interest rates on our operations, including interest rate swap agreements, interest rate swaptions, interest rate cap or floor contracts and futures or forward contracts. We may also purchase or short TBA, U.S. Treasury securities and U.S. Treasury futures contracts, purchase or write put or call options on TBA securities or we may invest in other types of mortgage derivative securities, such as interest-only securities, and synthetic total return swaps, such as the Markit IOS Index. When we use these types of derivatives to hedge the risk of interest-earning assets or interest-bearing liabilities, we may be subject to certain risks, including the risk that losses on a hedge position will reduce the funds available for payments to holders of our common stock and that the losses may exceed the amount we invested in the instruments.

Our profitability and the value of our investment portfolio (including derivatives used for hedging purposes) may be adversely affected during any period as a result of changing interest rates including resulting changes in forward yield curves. The following table quantifies the estimated changes in net interest income and investment portfolio value should interest rates go up or down by 50 and 100 basis points, assuming the yield curves of the rate shocks will be parallel to each other and the current yield curve. These estimates were compiled using a combination of third-party services, market data and internal models. All changes in income and value are measured as percentage changes from the projected net interest income and investment portfolio value at the base interest rate

45

scenario. The base interest rate scenario assumes interest rates as of June 30, 2011. Given the low level of interest rates, we also apply a floor of 0% for all anticipated interest rates included in our assumptions, such that any hypothetical interest rate decrease would have a limited positive impact on our funding costs beyond a certain level. However, because estimated prepayment speeds are unaffected by this floor, it is expected that an increase in our prepayment speeds as a result of a hypothetical interest rate decrease would result in an acceleration of our premium amortization and could result in reinvestment of such prepaid principal into lower yielding assets.

Actual results could differ materially from estimates, especially in the current market environment. The accuracy of the projected agency securities prices relies on assumptions that define specific agency securities spreads and varying prepayment assumptions at projected interest rate levels. To the extent that these estimates or other assumptions do not hold true, which is likely in a period of high price volatility, actual results will likely differ materially from projections and could be larger or smaller than the estimates in the table below. Moreover, if different models were employed in the analysis, materially different projections could result. In addition, while the tables below reflect the estimated impact of interest rate increases and decreases on a static portfolio, we may from time to time sell any of our agency securities as a part of our overall management of our investment portfolio.

Change in Interest Rate	Percentage Change in Projected Net Interest Income			Percentage Change in Projected Portfolio Value, with Effect of Derivatives
+100 Basis Points		-10.4	%		-1.2	%
+50 Basis Points		-4.7	%		-0.5	%
-50 Basis Points		1.0	%		0.1	%
-100 Basis Points		-4.7	%		-0.5	%

Prepayment Risk

Premiums and discounts associated with the purchase of agency securities are amortized or accreted into interest income over the projected lives of the securities, including contractual payments and estimated prepayments using the interest method. Furthermore, U.S. Government agency or U.S. Government entity buyouts of loans in imminent risk of default, loans that have been modified, or loans that have defaulted will generally be reflected as prepayments on agency securities and also increase the uncertainty around these estimates. Our policy for estimating prepayment speeds for calculating the effective yield is to evaluate published prepayment data for similar agency securities, market consensus and current market conditions. If the actual prepayment experienced differs from our estimate of prepayments, we will be required to make an adjustment to the amortization or accretion of premiums and discounts that would have an impact on future income.

Spread Risk

Our available-for-sale securities are reflected at their estimated fair value with unrealized gains and losses excluded from earnings and reported in OCI pursuant to ASC 320. As of June 30, 2011, the fair value of these securities was $39.9 billion. When the spread between the yield on our agency securities and U.S. treasury securities or swap rates widens, this could cause the value of our agency securities to decline, creating what we refer to as spread risk. The spread risk associated with our agency securities and the resulting fluctuations in fair value of these securities can occur independent of interest rates and may relate to other factors impacting the mortgage and fixed income markets such as liquidity or changes in required rates of return on different assets.

Liquidity Risk

The primary liquidity risk for us arises from financing long-term assets with shorter-term borrowings in the form of repurchase agreements. Our assets that are pledged to secure repurchase agreements are high-quality agency securities and cash. As of June 30, 2011, we had unrestricted cash and cash equivalents of $625.9 million

46

and unpledged agency securities of $2.1 billion available to meet margin calls on our repurchase agreements, derivative instruments and for other corporate purposes. However, should the value of our agency securities pledged as collateral suddenly decrease, margin calls relating to our repurchase agreements could increase, causing an adverse change in our liquidity position. As such, we cannot assure that we will always be able to renew (or roll) our repurchase agreements. In addition, our counterparties have the option to increase our haircuts (margin requirements) on the assets we pledge against repurchase agreements, thereby reducing the amount that can be borrowed against an asset even if they agree to renew or roll the repurchase agreement. Significantly higher haircuts can reduce our ability to leverage our portfolio or even force us to sell assets, especially if correlated with asset price declines or faster prepayment rates on our assets.

Extension Risk

The projected weighted-average life and the duration (or interest rate sensitivity) of our investments is based on our Manager’s assumptions regarding the rate at which the borrowers will prepay the underlying mortgage loans. In general, we use interest rate swaps and swaptions to help manage our funding cost on our investments in the event that interest rates rise. These swaps (or swaptions) allow us to reduce our funding exposure on the notional amount of the swap for a specified period of time by agreeing to pay a fixed-rate in exchange for receiving a floating rate that generally tracks our financing costs under our repurchase agreements.

However, if prepayment rates decrease in a rising interest rate environment, the average life or duration of our fixed-rate assets or the fixed-rate portion of the ARMs or other assets generally extends. This could have a negative impact on our results from operations, as our interest rate swap maturities are fixed and will, therefore, cover a smaller percentage of our funding exposure on our mortgage assets to the extent that their average lives increase due to slower prepayments. This situation may also cause the market value of our agency securities collateralized by fixed rate mortgages or hybrid ARMs to decline by more than otherwise would be the case while most of our hedging instruments (with the exception of short TBA mortgage positions, interest-only securities, Markit IOS Index total return swaps and certain other supplemental hedging instruments) would not receive any offsetting gains. In extreme situations, we may be forced to sell assets to maintain adequate liquidity, which could cause us to incur realized losses.

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 more so than does inflation. Changes in interest rates do not necessarily correlate with inflation rates or changes in inflation rates. Further, our consolidated financial statements are prepared in accordance with GAAP and our distributions are determined by our Board of Directors based primarily by our net income as calculated for income tax purposes. In each case, our activities and balance sheet are measured with reference to historical cost and/or fair market value without considering inflation.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act of 1934, as amended (the “Exchange Act”) reports 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 required disclosure based on the definition of “disclosure controls and procedures” as promulgated under the Exchange Act and the rules and regulations there under. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

47

We, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2011. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective.

Changes in Internal Controls over Financial Reporting

There have been no changes in our “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the three month or six month period ended June 30, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II.—OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be involved in various claims and legal actions arising in the ordinary course of business. As of June 30, 2011, we have no legal proceedings.

Item 1A. Risk Factors

There have been no material changes to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2010, except as described below.

You should carefully consider the risks described below and all other information contained in this interim report on Form 10-Q, including our interim consolidated financial statements and the related notes thereto before making a decision to purchase our securities. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or not presently deemed material by us, may also impair our operations and performance.

If any of the following risks actually occur, our business, financial condition or results of operations could be materially adversely affected. If that happens, the trading price of our securities could decline, and you may lose all or part of your investment.

We have no employees and our Manager is responsible for making all of our investment decisions. Certain of our Manager’s officers are employees of American Capital and are not required to devote any specific amount of time to our business and each of them may provide their services to American Capital, its affiliates and sponsored investment vehicles, which could result in conflicts of interest.

Because we have no employees, our Manager is responsible for making all of our investment decisions. Certain of our and our Manager’s officers are employees of American Capital or its affiliates and these persons do not devote their time exclusively to us. Our Manager’s investment committee consists of Malon Wilkus, John R. Erickson, Samuel A. Flax and Thomas A. McHale, each of whom is an officer of American Capital and has significant responsibilities to American Capital and certain of its portfolio companies, affiliated entities or managed funds. Gary Kain is our President and Chief Investment Officer and also serves as the President and a member of the parent company of our Manager, and he may have significant responsibilities for new funds that are managed by the parent company of our Manager or affiliated entities of our Manager. Because certain of our and our Manager’s officers are also responsible for providing services to American Capital and/or certain of its portfolio companies, affiliated entities or managed funds, they may not devote sufficient time to the management of our business operations.

American Capital has agreed that so long as the Manager or an affiliate of American Capital continues to manage our company, it will not sponsor another investment vehicle that invests predominantly in whole pool agency securities. This restriction does not prevent American Capital or an affiliate of American Capital from

48

investing in or sponsoring an investment vehicle that targets investments in agency securities so long as those investments are not predominately whole pool agency securities, and, as a result, American Capital or an affiliate of American Capital may compete with us. Our Manager has advised us that American Capital and its affiliates are sponsoring and investing in other investment vehicles, including investment vehicles that may make significant investments in agency securities, including whole pool agency securities. Our Manager and its employees are not restricted from participating in the management of such an entity.

Our Board of Directors has adopted investment guidelines that require that any investment transaction between us and American Capital or any affiliate of American Capital receive the prior approval of a majority of our independent directors. However, this policy does not eliminate the conflicts of interest that our and our Manager’s officers will face in making investment decisions on behalf of American Capital, any other American Capital-sponsored investment vehicles and us. Further, we do not have any agreement or understanding with American Capital that would give us any priority over American Capital, any of its affiliates, or any such American Capital-sponsored investment vehicle in opportunities to invest in agency securities. Accordingly, we may compete for access to the benefits that we expect our relationship with our Manager and American Capital to provide.

We may change our policies at any time without stockholder approval, including our investment policy, which may adversely affect our financial condition, results of operations, the market price of our common stock or our ability to pay dividends or distributions.

Our Board of Directors and management determine all of our policies, including our investment, financing and distribution policies. They may amend or revise these policies at any time without a vote of our stockholders. Changes in our investment guidelines, including a change that would permit us to invest in non-agency securities, could increase the risk profile of our investment portfolio. If that were to happen, non-agency mortgage-backed securities would be subject to all of the risks of the respective underlying mortgage loans, including delinquency and foreclosure, which could result in significant losses to us. Changes to our investment and other policies could also adversely affect our financial condition, results of operations, the market price of our common stock or our ability to pay dividends or distributions.

Federal Reserve programs to purchase securities could have an adverse impact on the agency securities in which we invest.

Beginning in November 2008, the Federal Reserve initiated a program to purchase direct obligations of Fannie Mae, Freddie Mac and the Federal Home Loan Bank and agency securities backed by Fannie Mae, Freddie Mac and Ginnie Mae. In total, this program resulted in the Federal Reserve purchasing $300 billion of direct obligations and $1.75 trillion of agency securities with the purchase program ending in the first quarter of 2010. One of the effects of this program has been to increase competition for available direct obligations and agency securities, with the result being an increase in pricing of such securities. The Federal Reserve may hold the direct obligations and agency mortgage securities to maturity or may sell them on the open market. For instance, in March 2011, the U.S. Treasury announced plans to start selling its remaining $142 billion of agency securities guaranteed by Fannie Mae or Freddie Mac. Sales by the Federal Reserve of the direct obligations or agency mortgage securities that it currently holds may reduce the market price of such securities. Reductions in the market price of agency mortgage securities may negatively impact our book value. In addition, the Federal Reserve initiated a program in November 2010 to purchase up to $600 billion of long-term U.S. Treasury securities that ended in June 2011 as part of its continuing effort to help stimulate the economy by reducing mortgage and interest rates. The expiration of the program could negatively affect our income or our net book value by impacting interest rate levels and the spread between mortgage rates and other interest rates. Thus, these actions could reduce the yields on assets that we are targeting for purchase, thereby reducing our net interest spreads.

49

The market price of our common stock may fluctuate significantly.

The market price and marketability of shares of our securities may from time to time be significantly affected by numerous factors, including many over which we have no control and that may not be directly related to us. These factors include the following:

• price and volume fluctuations in the stock market from time to time, which are often unrelated to the operating performance of particular companies;

• significant volatility in the market price and trading volume of securities of REITs or other companies in our sector, which is not necessarily related to the operating performance of these companies;

• changes in regulatory policies, tax guidelines and financial accounting and reporting standards, particularly with respect to REITs;

• actual or anticipated changes in our dividend policy and earnings or variations in operating results;

• any shortfall in revenue or net income or any increase in losses from levels expected by securities analysts;

• issuances of additional equity securities;

• additions or departures of key management personnel, or changes in our relationship with our Manager and American Capital;

• decreases in our net asset value per share;

• general economic trends and other external factors; and

• loss of major repurchase agreement providers.

Fluctuations in the trading price of our common stock may adversely affect the liquidity of the trading market for our common stock and, in the event that we seek to raise capital through future equity financings, our ability to raise such equity capital.
