NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

Organization

MFA Mortgage Investments, Inc. (the Company) was incorporated in Maryland on July 24, 1997 and began operations on April 10, 1998. The Company has elected to be treated as a real estate investment trust (REIT) for federal income tax purposes. In order to maintain its qualification as a REIT, the Company must comply with a number of requirements under federal tax law, including that it must distribute at least 90% of its annual net taxable income to its stockholders, subject to certain adjustments.

Summary of Significant Accounting Policies

(a) Basis of Presentation

The accompanying interim unaudited financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (GAAP) have been condensed or omitted according to such SEC rules and regulations. Management believes, however, that these disclosures are adequate to make the information presented therein not misleading. The accompanying financial statements should be read in conjunction with the financial statements and notes thereto included in the Companys Annual Report on Form 10-K for the year ended December 31, 2006. In the opinion of management, all normal and recurring adjustments necessary to present fairly the financial condition of the Company at September 30, 2007 and results of operations for all periods presented have been made. The results of operations for the nine-month period ended September 30, 2007 should not be construed as indicative of the results to be expected for the full year.

The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in accordance with GAAP. 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 revenues and expenses during the reporting period. Actual results could differ from those estimates.

(b) MBS/Investment Securities

The Companys investment securities are comprised primarily of hybrid and adjustable-rate MBS (collectively, ARM-MBS) that are issued or guaranteed as to principal and/or interest by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. government, such as Ginnie Mae (collectively, Agency MBS), or are rated AAA by at least one nationally recognized rating agency. Hybrid MBS have interest rates that are fixed for a specified period and, thereafter, generally reset annually. To a lesser extent, the Company also holds investments in non-Agency MBS, mortgage-related securities and other investments that are rated below AAA. At September 30, 2007, the Company held securities with a carrying value of $11.1 million rated below AAA, including unrated investment securities.

The Company accounts for its investment securities in accordance with Statement of Financial Accounting Standards (FAS) No. 115, Accounting for Certain Investments in Debt and Equity Securities, which requires that investments in securities be designated as either held-to-maturity, available-for-sale or trading at the time of acquisition. All of the Companys investment securities are designated as available-for-sale and are carried at their estimated fair value with unrealized gains and losses excluded from earnings and reported in other comprehensive income, a component of Stockholders Equity. The Company determines the fair value of its investment securities based upon prices obtained from a third-party pricing service and broker quotes.

Although the Company generally intends to hold its investment securities until maturity, it may, from time to time, sell any of its securities as part of the overall management of its business. The available-for-sale designation provides the Company with the flexibility to sell any of its investment securities. Upon the sale of an investment security, any unrealized gain or loss is reclassified out of accumulated other comprehensive income to earnings as a realized gain or loss using the specific identification method. (See Note 3.)

Interest income is accrued based on the outstanding principal balance of the investment securities and their contractual terms. Premiums and discounts associated with Agency MBS and MBS rated AAA are amortized into interest income over the life of such securities using the effective yield method, adjusted for actual prepayment activity in accordance with FAS No. 91, Accounting for Nonrefundable Fees and Costs Associated with Originating or Acquiring Loans and Initial Direct Costs of Leases. Certain of the Agency MBS owned by the Company contractually provide for negative amortization, which occurs when the full amount of the stated coupon interest due on the distribution date for an MBS is not received from the underlying mortgages. The Company

MFA MORTGAGE INVESTMENTS, INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

recognizes such interest shortfall on its Agency MBS as interest income with a corresponding increase in the related Agency MBS principal value (i.e., par) as the interest shortfall is guaranteed by the issuing agency.

Interest income on the Companys securities rated below AAA, including unrated securities, is recognized in accordance with Emerging Issues Task Force (EITF) of the Financial Accounting Standards Board (FASB) Consensus No. 99-20, Recognition of Interest Income and Impairment on Purchased and Retained Beneficial Interests in Securitized Financial Assets (EITF 99-20). Pursuant to EITF 99-20, cash flows from a security are estimated applying assumptions used to determine the fair value of such security and the excess of the future cash flows over the investment is recognized as interest income under the effective yield method. The Company reviews and makes adjustments to its cash flow projections at least quarterly and monitors these projections based on input and analysis received from external sources, internal models, and its judgment about interest rates, prepayment rates, the timing and amount of credit losses, and other factors. Changes in cash flows from those originally projected, or from those estimated at the last evaluation, may result in a prospective change in interest income recognized on such securities. Certain of these securities rated below AAA were purchased at a discount to par value, with a portion of such discount considered credit protection against future credit losses under various economic environments. The initial credit protection (i.e., discount) of these MBS may be adjusted over time, based on review of the investment or, if applicable, its underlying collateral, actual and projected cash flow from such collateral, economic conditions and other factors. If the performance of these securities is more favorable than forecasted, a portion of the amount designated as credit protection may be accreted into interest income over time. Conversely, if the performance of these securities is less favorable than forecasted, impairment charges and a corresponding write down of such security to a new cost basis could result. The Company did not have any impairment charges against such investments during the three or nine months ended September 30, 2007 and September 30, 2006.

(c) Cash and Cash Equivalents

Cash and cash equivalents include cash on deposit and investments in overnight money market funds, all of which have original maturities of three months or less. The carrying amount of cash equivalents approximates their fair value.

(d) Other-Than-Temporary Impairment/Credit Risk

The Company limits its exposure to credit losses on its investment portfolio by requiring that at least 50% of its investment portfolio consist of hybrid and adjustable-rate MBS that are either (i) issued or guaranteed by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. government, such as Ginnie Mae, or (ii) rated in one of the two highest rating categories by at least one nationally recognized rating agency. The remainder of the Companys investment portfolio may consist of direct or indirect investments in: (i) other types of MBS; (ii) residential mortgage loans; (iii) collateralized debt obligations and other related securities; (iv) real estate; (v) securities issued by REITs, limited partnerships and closed-end funds; (vi) high-yield corporate securities and other fixed income instruments (corporate or government); and (vii) other types of assets approved by the Companys Board of Directors (the Board) or a committee thereof. At September 30, 2007, 88.6% of the Companys assets consisted of Agency MBS and related receivables, 8.1% were MBS rated AAA by Standard & Poors Corporation, a nationally recognized rating agency, and related receivables and 2.9% were cash and cash equivalents; combined these assets comprised 99.6% of the Companys total assets.

The Company assesses its investment securities for other-than-temporary impairment on at least a quarterly basis. When the fair value of an investment is less than its amortized cost at the balance sheet date of the reporting period for which impairment is assessed, the impairment is designated as either temporary or other-than-temporary. If it is determined that impairment is other-than-temporary, then an impairment loss is recognized in earnings reflecting the entire difference between the investments cost basis and its fair value at the balance sheet date of the reporting period for which the assessment is made. The measurement of the impairment is not permitted to include partial recoveries subsequent to the balance sheet date. Following the recognition of an other-than-temporary impairment, the fair value of the investment becomes the new cost basis of the investment and is not adjusted for subsequent recoveries in fair value through earnings. Because managements assessments are based on factual information as well as subjective information available at the time of assessment, the determination as to whether an other-than-temporary decline exists and, if so, the amount considered impaired is also subjective and, therefore, constitutes material estimates that are susceptible to significant change.

MFA MORTGAGE INVESTMENTS, INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

Upon a decision to sell an impaired available-for-sale investment security on which the Company does not expect the fair value of the investment to fully recover prior to the expected time of sale, the investment shall be deemed other-than-temporarily impaired in the period in which the decision to sell is made. The Company recognizes an impairment loss when the impairment is deemed other-than-temporary even if a decision to sell has not been made. The Company had no other-than-temporarily impaired MBS at September 30, 2007 and did not recognize any impairment charges against its MBS portfolio during the nine months ended September 30, 2007 and September 30, 2006.

(e) Goodwill

The Company accounts for its goodwill in accordance with FAS No. 142, Goodwill and Other Intangible Assets (FAS 142) which provides, among other things, how entities are to account for goodwill and other intangible assets that arise from business combinations or are otherwise acquired. FAS 142 requires that goodwill be tested for impairment annually or more frequently under certain circumstances. At September 30, 2007 and December 31, 2006, the Company had goodwill of $7.2 million, which represents the unamortized portion of the excess of the fair value of the common stock issued over the fair value of net assets acquired in connection with its formation in 1998. Goodwill is tested for impairment at least annually at the entity level. Through September 30, 2007, the Company had not recognized any impairment against its goodwill.

(f) Real Estate

At September 30, 2007, the Company indirectly held 100% of the ownership interest in Lealand Place, a 191-unit apartment property located in Lawrenceville, Georgia (Lealand Place), which is consolidated with the Company. This property was acquired through a tax-deferred exchange under Section 1031 of the Internal Revenue Code of 1986, as amended (the Code). (See Note 5.)

The property, capital improvements and other assets held in connection with this investment are carried at cost, net of accumulated depreciation and amortization. Maintenance, repairs and minor improvements are charged to expense in the period incurred, while real estate assets, except land, and capital improvements are depreciated over their useful life using the straight-line method.

(g) Real Estate Held-for-Sale/Discontinued Operations

The Company accounts for its held-for-sale real estate assets in accordance with FASB Statement No. 144, Accounting for the Impairment or Disposal of Long Lived Assets (FAS 144). Among other things, FAS 144 provides that a long-lived asset classified as held-for-sale shall: (i) not be depreciated while classified as held-for-sale; (ii) be measured at the lower of its carrying amount or fair value less cost to sell; (iii) result in a loss recognized for any initial or subsequent write-down to fair value less cost to sell or a gain recognized for any subsequent increase in fair value less cost to sell, but not in excess of the cumulative loss previously recognized. A gain or loss, not previously recognized, that results from the sale of a long-lived asset shall be recognized at the date of sale. In accordance with FAS 144, as amended by Statement No. 154, Accounting Changes and Error Corrections (FAS 154), revenues and expenses for the Companys indirect interest in a property classified as held-for-sale or sold have been restated as discontinued operations, on a net basis for each of the periods presented. This reclassification/restatement had no effect on the Companys reported net income. (See Note 5.)

During the first quarter of 2006, the Company sold its 100% indirect membership interest in Greenhouse Holdings, LLC (Greenhouse), which held a 128-unit multi-family apartment building in Omaha, Nebraska known as The Greenhouse. The transaction resulted in a gain of $4.8 million net of selling costs and a built-in gains tax of $1.8 million. In addition, a $135,000 mortgage prepayment penalty was incurred on the satisfaction of the mortgage secured by such property. Prior to the quarter in which the sale of Greenhouse occurred, there was no definitive plan to sell such property. During the third quarter of 2007, the Company recognized income of $257,000 related to a reduction of the $1.8 million of built-in-gains taxes previously recognized on the sale of Greenhouse.

On June 30, 2006, the Company classified its indirect investment in Cameron at Hickory Grove Apartments, a 201-unit multi-family apartment complex in Charlotte, North Carolina (Cameron), as held-for-sale. Upon the reclassification, Cameron was reviewed for impairment and it was determined that Camerons carrying value approximated its fair value less cost to sell. The sale of Cameron during the fourth quarter of 2006 ultimately resulted in a net loss of $408,000. In addition, a prepayment penalty of $577,000 was incurred on the satisfaction of the mortgage secured by such property.

In accordance with FAS 144, the historical results of operations from Greenhouse and Cameron have been restated, on a net basis, as a component of discontinued operations.

(h) Repurchase Agreements

The Company finances the acquisition of its MBS through repurchase agreements. Under these repurchase agreements, the Company sells securities to a lender and agrees to repurchase the same securities in the future for a price that is higher than the original sale price. The difference between the sale price that the Company receives and the repurchase price that the Company pays represents interest paid to the lender. Although structured as a sale and repurchase, under repurchase agreements, the Company pledges its securities as collateral to secure a loan which is equal in value to a specified percentage of the estimated fair value of the pledged collateral, while the Company retains beneficial ownership of the pledged collateral. At the maturity of a repurchase agreement, the Company is required to repay the loan and concurrently receives back its pledged collateral from the lender. With the consent of the lender, the Company may renew a repurchase agreement at the then prevailing financing terms. Margin calls, whereby a lender requires that the Company pledge additional securities or cash as collateral to secure borrowings under its repurchase agreements with such lender, are routinely experienced by the Company as the value of the MBS pledged as collateral declines due to scheduled monthly amortization and prepayments of principal on such MBS. In addition, margin calls may also occur when the fair value of the MBS pledged as collateral declines due to increases in market interest rates or other market conditions. Through September 30, 2007, the Company had satisfied all of its margin calls. (See Note 6.)

Original terms to maturity of the Companys repurchase agreements range from one month to 60 months. Should a counterparty decide not to renew a repurchase agreement at maturity, the Company must either refinance elsewhere or be in a position to satisfy this obligation. If, during the term of a repurchase agreement, a lender should file for bankruptcy, the Company might experience difficulty recovering its pledged assets and may have an unsecured claim against the lenders assets for the difference between the amount loaned to the Company plus interest due to the counterparty and the estimated fair value of the collateral pledged to such lender. To reduce this risk, the Company enters into repurchase agreements only with institutions whose long-term debt rating is single A or better or, if applicable, whose parent or holding company is rated single A or better (Qualifying Institutions) as determined by at least one nationally recognized rating agency, such as Moodys Investors Services, Inc., Standard & Poors Corporation or Fitch, Inc. (collectively, the Rating Agencies), where applicable. If the minimum criterion is not met, the Company will not enter into repurchase agreements with a lender without the specific approval of the Board. In the event an existing lender is downgraded below single A, the Company will seek the approval of the Board before entering into additional repurchase agreements with that lender. The Company generally seeks to diversify its exposure by entering into repurchase agreements with at least four separate lenders with a maximum loan from any lender of no more than three times the Companys stockholders equity. At September 30, 2007, the Company had outstanding balances under repurchase agreements with 14 separate lenders with a maximum net exposure (the difference between the amount loaned to the Company including interest payable and the fair value of the security pledged by the Company as collateral including accrued interest on such securities) to a single lender of $54.8 million.

Prior to the first quarter of 2006, the Company had, in some cases, purchased MBS from a counterparty and subsequently financed the acquisition of such MBS through repurchase agreements, which financing was also collateralized by such MBS, with the same counterparty (a Same Party Transaction). The Company recorded the acquisition of these MBS as assets and the related financings under repurchase agreements as liabilities on its consolidated balance sheets, with changes in the fair value of these MBS recorded in other comprehensive income, a component of stockholders equity. The corresponding interest income earned on these MBS and interest expense incurred on the related repurchase agreements were reported gross on the Companys consolidated statements of income.

In June 2007, the FASB discussed proposed FASB Staff Position (FSP) FAS 140-d, Accounting for Transfers of Financial Assets and Repurchase Financing Transactions, which addresses Same Party Transactions. Among other things, the FASB tentatively determined that: (1) the FSP should be effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years and that earlier application should not be permitted; (2) the guidance should be applied to existing repurchase financings as of the beginning of the fiscal year in which the FSP is initially applied as a cumulative effect adjustment; and (3) the cumulative effect of the change in accounting principle should be recognized as an adjustment to the opening balance of retained earnings (or other appropriate components of equity or net assets in the statement of financial position). The FASB issued the proposed FSP in July 2007 and comments were due by September 14, 2007. Based on the FASBs tentative position, the Company does not expect that the issuance of the FSP will have any impact on its prior financial statements. At September 30, 2007, the Company had no Same Party Transactions.

(i) Earnings per Common Share (EPS)

Basic EPS is computed by dividing net income available to holders of common stock by the weighted average number of shares of common stock outstanding during the period. Diluted EPS is computed by dividing net income available to holders of common stock by the weighted average shares of common stock and common equivalent shares outstanding during the period. For the diluted EPS calculation, common equivalent shares outstanding includes the weighted average number of shares of common stock outstanding adjusted for the effect of dilutive unexercised stock options outstanding using the treasury stock method. Under the treasury stock method, common equivalent shares are calculated assuming that all dilutive common stock equivalents are exercised and the proceeds along with future compensation expenses for unvested stock options are used to repurchase shares of the Companys outstanding common stock at the average market price during the reported period. No common share equivalents are included in the computation of any diluted per share amount for a period in which a net operating loss is reported. (See Note 9.)

(j) Comprehensive Income/Loss

Comprehensive income/(loss) for the Company includes net income/(loss) and the change in net unrealized gains/(losses) on investment securities and derivative instruments. (See Note 10.)

(k) U.S. Federal Income Taxes

The Company has elected to be taxed as a REIT under the provisions of the Code and the corresponding provisions of state law. The Company expects to operate in a manner that will enable it to continue to be taxed as a REIT. A REIT is not subject to tax on its earnings to the extent that it distributes its taxable income to stockholders. As such, no provision for current or deferred income taxes has been made in the accompanying consolidated financial statements.

Under the Built-in Gain Rules of the Code, a REIT is subject to a corporate tax if it disposes of an asset acquired from a C corporation during the ten-year period following the initial acquisition of such asset. Such built-in gain tax is imposed at the highest regular corporate tax rate on the lesser of (i) the amount of gain recognized by the REIT at the time of the sale or disposition of such asset or (ii) the amount of such assets built-in gains at the time the asset was acquired from the non-REIT C corporation. During the first quarter of 2006, the Company was subject to a built-in gains tax of $1.8 million in connection with the sale of Greenhouse, which, net of such tax and selling expenses, resulted in a gain of $4.8 million. During the quarter ended September 30, 2007, the Company recognized income of $257,000 related to a reduction of the $1.8 million of built-in gains tax previously recognized on the sale of Greenhouse. (See Note 5.)

(l) Derivative Financial Instruments/Hedging Activity

The Company hedges a portion of its interest rate risk through the use of derivative financial instruments, comprised of Swaps and Caps (collectively, Hedging Instruments). The Company accounts for Hedging Instruments in accordance with FAS No. 133, Accounting for Derivative Instruments and Hedging Activities, (FAS 133) as amended by FAS No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities, and FAS No. 149 Amendment of Statement 133 on Derivative Instruments and Hedging Activities. The Companys Hedging Instruments are carried on the balance sheet at their fair value, as assets, if their fair value is positive, or as liabilities, if their fair value is negative. Since the Companys Hedging Instruments are designated as cash flow hedges, the change in the fair value of any such instrument is recorded in other comprehensive income for hedges that qualify as effective and is transferred from other comprehensive income to earnings as the hedged liability affects earnings. The ineffective amount of all Hedging Instruments, if any, is recognized in earnings each quarter. To date, except for gains and losses realized on Swaps terminated early, the Company has not recognized any change in the value of its Hedging Instruments in earnings as a result of the hedge or a portion thereof being ineffective.

Upon entering into hedging transactions, the Company documents the relationship between the Hedging Instruments and the hedged liability. The Company also documents its risk-management policies, including objectives and strategies, as they relate to its hedging activities. The Company assesses, both at inception of a hedge and on an on-going basis, whether or not the hedge is highly effective, as defined by FAS 133. The Company discontinues hedge accounting on a prospective basis and recognizes changes in the estimated fair value reflected in earnings when: (i) it is determined that the derivative is no longer effective in offsetting cash flows of a hedged item (including hedged items such as forecasted transactions); (ii) it is no longer probable that the forecasted transaction will occur; or (iii) it is determined that designating the derivative as a Hedging Instrument is no longer appropriate.

The Company utilizes Hedging Instruments to manage a portion of its interest rate risk and does not anticipate entering into derivative transactions for speculative or trading purposes. In order to limit credit risk

MFA MORTGAGE INVESTMENTS, INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

associated with the counterparties to derivative instruments, the Companys policy is to enter into derivative contracts with Qualifying Institutions. (See Note 4.)

Interest Rate Swaps

No cost is incurred by the Company at the inception of a Swap; however, in certain cases, the Company is required to pledge cash or securities equal to a specified percentage of the notional amount of the Swap to the counterparty as collateral. When the Company enters into a Swap, it agrees to pay a fixed rate of interest and to receive a variable interest rate, generally based on the London Interbank Offered Rate (LIBOR). The Companys Swaps are designated as cash flow hedges against the benchmark interest rate risk associated with its borrowings.

All changes in the value of Swaps are recorded in accumulated other comprehensive income. If it becomes probable that the forecasted transaction (which in this case refers to interest payments to be made under the Companys short-term borrowing agreements) will not occur by the end of the originally specified time period, as documented at the inception and throughout the term of the hedging relationship, then the related gain or loss in accumulated other comprehensive income would be recognized through earnings.

Realized gains and losses resulting from the termination of a Swap are initially recorded in accumulated other comprehensive income as a separate component of stockholders equity. The gain or loss from a terminated Swap remains in accumulated other comprehensive income until the forecasted interest payments affect earnings. However, if it is probable that the forecasted interest payments will not occur, then the entire gain or loss is recognized through earnings.

Interest Rate Caps

A one-time fee (i.e., a premium) is paid upon purchasing a Cap. Pursuant to the terms of a Cap, the Company will receive cash payments if the interest rate index specified in a Cap increases above the contractually specified level. Therefore, Caps have the effect of capping the interest rate on a portion of the Companys borrowings, equal to the notional amount of the active Caps, to the rate specified in the Cap agreement.

In order for the Companys Caps to qualify for hedge accounting, upon entering into the Cap, the Company must anticipate that the hedge will be highly effective, as defined by FAS 133, in limiting the Companys cost beyond the Cap threshold on its matching (on an aggregate basis) anticipated repurchase agreements during the active period of the Cap. Provided that the hedge remains effective, changes in the estimated fair value of the Caps are included in other comprehensive income. Upon commencement of the Cap active period, the premium paid to enter into the Cap is amortized to interest expense. The periodic amortization of Cap premiums are based on an allocation of the premium, determined at inception of the hedge, for the monthly components on an estimated fair value basis. Payments received in connection with Caps, if any, reduce interest expense. If it is determined that a Cap is not effective, the premium would be reduced and a corresponding charge made to interest expense, for the ineffective portion of the Cap. The maximum cost related to the Companys Caps is limited to the premium paid to enter into the Cap.

(m) Adoption of New Accounting Standards

On January 1, 2007, the Company adopted FASB Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxes (FIN 48). FIN 48 prescribes a recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Companys adoption of FIN 48 did not have an impact on the Companys financial statements.

Effective January 1, 2007, the Company adopted FAS No. 155, Accounting for Certain Hybrid Instruments (FAS 155), an amendment to FAS 133 and FAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities (FAS 140). Among other things, FAS 155: (i) permits fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation; (ii) clarified which interest-only strips and principal-only strips are not subject to the requirements of FAS 133; (iii) established a requirement to evaluate interests in securitized financial assets to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain an embedded derivative requiring bifurcation; (iv) clarified that concentrations of credit risk in the form of subordination are not embedded derivatives; and (v) amended FAS 140 to eliminate the prohibition on a qualifying special-purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

Securitized interests which only contain an embedded derivative that is tied to the prepayment risk of the underlying prepayable financial assets and for which the investor does not control the right to accelerate the settlement of such financial assets are excluded under a scope exception adopted by the FASB. As a result of this scope exception, none of the Companys assets were subject to FAS 155. The Company continues to record changes in the market value of its investment securities through other comprehensive income. Therefore, the adoption of FAS 155 did not have any impact on the Companys financial position, results of operations or cash flows. However, if future investments by the Company in securitized financial assets do not meet the scope exception to FAS 155, the Companys results of operations may exhibit future volatility if such investments are required to be bifurcated or marked to market value in their entirety through the income statement.

(n) Recently Issued Accounting Standards

In September 2006, the FASB issued FAS No. 157, Fair Value Measurements (FAS 157), which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. FAS 157 is effective for fiscal years beginning after November 15, 2007 and, with certain exceptions which are not believed to be applicable to the Company, is to be applied prospectively. Earlier application is permitted provided that the reporting entity has not yet issued interim or annual financial statements for that fiscal year. The Company did not elect to early adopt FAS 157 and is currently evaluating the impact that the adoption of FAS 157 will have on its consolidated financial statements.

In February 2007, the FASB issued FAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (FAS 159). FAS 159 permits entities to elect to measure many financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings at each subsequent reporting date. FAS 159 is effective for the Company commencing January 1, 2008 on a prospective basis, as the Company did not elect to early adopt FAS 159. A decision to elect the fair value option for an eligible financial instrument, which can be made on an instrument by instrument basis, is irrevocable. The Company is currently evaluating the impact that the adoption of FAS 159 will have on its consolidated financial statements.

In April 2007, the FASB issued FIN No. 39-1, Amendment of FASB Interpretation No. 39. (FIN 39-1). FIN 39-1 defines right of setoff and specifies what conditions must be met for a derivative contract to qualify for this right of setoff. FIN 39-1 also addresses the applicability of a right of setoff to derivative instruments and clarifies the circumstances in which it is appropriate to offset amounts recognized for those instruments in the balance sheet. In addition, FIN 39-1 permits offsetting of fair value amounts recognized for multiple derivative instruments executed with the same counterparty under a master netting arrangement and fair value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from the same master netting arrangement as the derivative instruments. This interpretation is effective for fiscal years beginning after November 15, 2007, with early application permitted. The Company is currently evaluating the impact that the adoption of FIN 39-1 will have on its consolidated financial statements.

In May 2007, the FASB issued FIN No. 46(R)-7, Application of FASB Interpretation No. 46(R) to Investment Companies (FIN 46(R)-7). FIN 46(R)-7 amends the scope of the exception to FIN 46(R), Consolidation of Variable-Interest Entities (revised December 2003) an interpretation of Accounting Research Bulletin No. 51, (FIN 46(R)) to state that investments accounted for at fair value in accordance with the specialized accounting guidance in the American Institute of Certified Public Accountants (AICPA) Audit and Accounting Guide, Investment Companies, (the Guide) are not subject to consolidation under FIN 46(R). This interpretation is effective for fiscal years beginning on or after December 15, 2007. The Company is currently evaluating the impact, if any, that the adoption of FIN 46(R)-7 will have on its consolidated financial statements.

In June 2007, the AICPA issued Statement of Position (SOP) 07-01 Clarification of the Scope of the Audit and Accounting Guide Investment Companies and Accounting by Parent Companies and Equity Method Investors for Investments in Investment Companies (SOP 07-1) which provides guidance for determining whether an entity is within the scope of the Guide. On October 17, 2007, FASB decided to issue a proposed FSP that would indefinitely defer the effective date of SOP 07-1 and that early adoption of SOP 07-1 will not be permitted during such deferral period.

(o) Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation.

Agency MBS: Although unrated, Agency MBS carry an implied AAA rating. Agency MBS are guaranteed as to principal and/or interest by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. government, such as Ginnie Mae. The payment of principal and/or interest on Fannie Mae and Freddie Mac MBS is guaranteed by those respective agencies and the payment of principal and/or interest on Ginnie Mae MBS is backed by the full faith and credit of the U.S. government.

Non-Agency MBS: Non-Agency MBS are certificates that are backed by pools of single-family and multi-family mortgage loans, which are not guaranteed by the U.S. government, any federal agency or any federally chartered corporation. Non-Agency MBS may be rated from AAA to B by one or more of the Rating Agencies or may be unrated. The rating indicates the credit worthiness of the investment (i.e., the obligors ability to meet its financial commitment on the obligation).

Other Investments: At September 30, 2007, the Companys other investment securities were comprised of income notes. Income notes are unrated securities collateralized by capital securities of a diversified pool of issuers, consisting primarily of depository institutions and insurance companies.

The Company monitors the performance and market value of its investment securities portfolio on an ongoing basis. At September 30, 2007, the Company had 189 securities, with an amortized cost of $1.168 billion and fair value of $1.148 billion, that had unrealized losses for 12 months or more. At September 30, 2007, these securities had gross unrealized losses of $19.5 million. The following table presents the gross unrealized losses and the estimated fair value of the Companys investment securities, aggregated by investment category or rating and length of time that such securities have been in a continuous unrealized loss position, at September 30, 2007.

At September 30, 2007, the Company determined that it had the intent and ability to continue to hold those investment securities on which it had unrealized losses until recovery of such unrealized losses or until maturity, such that the impairment of these securities was considered temporary. However, such assessment may change over time given, among other things, the dynamic nature of interest rate markets and other variables. Future sales or changes in the Companys assessment of its ability and/or intent to hold impaired investment securities until recovery or maturity could result in the Company recognizing other-than-temporary impairment charges or realized losses in the future.

During the nine months ended September 30, 2007, the Company sold 30 MBS, with an aggregate amortized cost of $727.9 million. In connection with these sales, the Company realized net losses of $22.1 million, of which $22.0 million were realized in the quarter ended September 30, 2007. During the nine months ended September 30, 2006, the Company sold 84 MBS with an aggregate amortized cost of $1.867 billion, resulting in net realized losses of $23.1 million, comprised of gross losses of $25.2 million and gross gains of $2.1 million.

Hedging Instruments

In connection with the Companys interest rate risk management, the Company periodically hedges a portion of its interest rate risk by entering into derivative financial instrument contracts. At September 30, 2007, the Companys derivatives were comprised of Swaps, which had the effect of modifying the repricing characteristics of the Companys repurchase agreements and cash flows on such liabilities. The use of Hedging Instruments 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. In addition, the Company is required to pledge assets as collateral for certain of its Swaps, which amount varies over time based on the market value, notional amount and remaining term of the Swap. At September 30, 2007 and December 31, 2006, the Company had MBS pledged as collateral against its Swaps of $27.0 million and $13.5 million, respectively. In order to mitigate its exposure to counterparty-related risk associated with its Hedging Instruments, the Companys policy is to enter into derivative transactions only with Qualifying Institutions. In the event of a default by the counterparty, the Company may not receive payments provided for under the terms of the Hedging Instrument, could incur a loss for the remaining unamortized premium cost of Caps and could have difficulty obtaining its assets pledged as collateral for Swaps.

(a) Interest Rate Swaps

Swaps are used by the Company to lock in a fixed interest rate on a portion of its current and anticipated future 30-day term repurchase agreements. During the three and nine months ended September 30, 2007, the Company terminated Swaps of $261.6 million and $305.2 million, respectively, resulting in net losses of $560,000 and $384,000, respectively. Correspondingly, the Company also satisfied the repurchase agreements that such Swaps hedged.

(b) Interest Rate Caps

Caps are designated by the Company as cash flow hedges against interest rate risk associated with the Companys existing and forecasted repurchase agreements. When the 30-day LIBOR increases above the rate specified in the Cap Agreement during the effective term of the Cap, the Company receives monthly payments from its Cap counterparty. The Company had no Caps at September 30, 2007.

Real Estate and Discontinued Operations

(a) Real Estate

The Companys investment in real estate at September 30, 2007 and December 31, 2006 was comprised of an indirect 100% ownership interest in Lealand Place, a 191-unit apartment property located in Lawrenceville, Georgia. The following table presents the summary of assets and liabilities of Lealand Place at September 30, 2007 and December 31, 2006.

(1) The mortgage collateralized by Lealand Place is non-recourse, subject to customary non-recourse exceptions, which generally means that the lenders final source of repayment in the event of default is foreclosure of the property securing such loan. At September 30, 2007 and December 31, 2006, the mortgage had a fixed interest rate of 6.87%, which contractually matures on February 1, 2011 and is subject to a penalty if prepaid. In January 2005, the Company loaned Lealand Place $150,000 to fund operations, of which $120,000 and $150,000 remained outstanding at September 30, 2007 and December 31, 2006, respectively. This loan and the related interest are eliminated in consolidation.

The following table presents the summary results of operations for Lealand Place, for the three and nine months ended September 30, 2007 and 2006.

(b) Discontinued Operations

The Companys discontinued operations for the three and nine months ended September 30, 2006 reflect the operating results for Cameron, which was sold during the fourth quarter of 2006, and Greenhouse, which was sold during the first quarter of 2006. The sale of Greenhouse resulted in the Company realizing a gain of $4.8 million, net of a built-in gains tax of $1.8 million and a mortgage prepayment penalty of $135,000 incurred upon satisfying the mortgage secured by Greenhouse. During the quarter ended September 30, 2007, the Company recognized income of $257,000 related to a reduction of the built-in gains tax previously recognized on the sale of Greenhouse. The historical results of operations for both Cameron and Greenhouse, which are neither individually nor in the aggregate material to the Company, have been restated and reported as a net component of discontinued operations.

Repurchase Agreements

The Companys repurchase agreements are collateralized by the Companys MBS and typically bear interest at rates that are LIBOR-based. At September 30, 2007, the Companys repurchase agreements had a weighted average remaining contractual maturity of six months and an effective repricing period of 20 months with the impact of related derivative hedges. At December 31, 2006, the Companys repurchase agreements had a weighted average remaining contractual maturity of 11 months and an effective repricing period of 15 months with the impact of related derivative hedges.

The Company pays monthly rent pursuant to each of its operating leases. Effective March 31, 2007, the Company consolidated its existing leases for office space at its corporate headquarters and entered into an amended lease for such space as well as newly-leased additional office space. As a result, the Company increased its total leased space at its headquarters to meet its operating needs. Under the current lease agreement, the Companys lease for its corporate headquarters extends through April 30, 2017 and provides for aggregate cash payments ranging from approximately $1.0 million to $1.4 million per year, paid on a monthly basis, exclusive of escalation charges and landlord incentives. In connection with this lease, the Company established a $350,000 irrevocable standby letter of credit in lieu of lease security for the benefit of the landlord through April 30, 2017. The letter of credit may be drawn upon by the landlord in the event that the Company defaults under certain terms of the lease. In addition, at September 30, 2007, the Company had a lease through December 2011 for its off-site back-up facilities located in Rockville Centre, New York, which provides for, among other things, rent of approximately $27,000 per year, paid on a monthly basis.

Equity Compensation, Employment Agreements and Other Benefit Plans

(a) 2004 Equity Compensation Plan

In accordance with the terms of the 2004 Plan, directors, officers and employees of the Company and any of its subsidiaries and other persons expected to provide significant services (of a type expressly approved by the Compensation Committee of the Board as covered services for these purposes) for the Company and any of its subsidiaries are eligible to receive grants of stock options (Options), restricted stock, phantom shares, DERs and other stock-based awards under the 2004 Plan.

In general, subject to certain exceptions, stock-based awards relating to a maximum of 3.5 million shares of common stock may be granted under the 2004 Plan; forfeitures and/or awards that expire unexercised do not count towards such limit. At September 30, 2007, 2.3 million shares of common stock remained available for grant under the 2004 Plan. Subject to certain exceptions, a participant may not receive stock-based awards in excess of 500,000 shares of common stock in any one-year and no award may be granted to any person who, assuming exercise of all Options and payment of all awards held by such person, would own or be deemed to own more than 9.8% of the outstanding shares of the Companys capital stock. Unless previously terminated by the Board, awards may be granted under the 2004 Plan until the tenth anniversary of the date that the Companys stockholders approved such plan.

Pursuant to Section 422(b) of the Code, in order for stock options granted under the 2004 Plan and vesting in any one calendar year to qualify as an incentive stock option (ISO) for tax purposes, the market value of the common stock, as determined on the date of grant, shall not exceed $100,000 during a calendar year. The exercise price of an ISO may not be lower than 100% (110% in the case of an ISO granted to a 10% stockholder) of the fair market value of the common stock on the date of grant. The exercise price for any other type of Option so issued may not be less than the fair market value on the date of grant. Each Option is exercisable after the period or periods specified in the award agreement, which will generally not exceed ten years from the date of grant. Options will be exercisable at such times and subject to such terms as determined by the Compensation Committee.

At September 30, 2007, an aggregate of 962,000 shares of common stock were subject to outstanding Options under the 2004 Plan, all of which were fully vested and exercisable, with a weighted average exercise price of $9.33. There were no options granted during the nine months ended September 30, 2007 and September 30, 2006. The Company recorded compensation expense for Options of $0 and $5,000 for the three and nine months ended September 30, 2007, respectively, and $120,000 and $359,000 for the three and nine months ended September 30, 2006, respectively. As of September 30, 2007, the aggregate intrinsic value of total Options outstanding was $318,000. During the nine months ended September 30, 2007, no Options expired unexercised nor were any options exercised.

The Company issued 0 shares and 28,004 shares of restricted common stock during the three and nine months ended September 30, 2007, respectively and recognized compensation expense of $7,000 and $121,000, respectively related to the vesting of restricted shares. During the three and nine months ended September 30, 2006, the Company issued 0 shares and 16,502 shares of restricted common stock, respectively, and recognized compensation expense of $0 and $100,000, respectively, related to the vesting of restricted shares. At September 30, 2007, the Company had unrecognized compensation expense of $63,000 related to unvested shares of restricted common stock previously granted.

A DER is a right to receive, as specified by the Compensation Committee at the time of grant, a distribution equal to the dividend distributions paid on a share of common stock. DERs may be granted separately or together with other awards and are paid in cash or other consideration at such times, and in accordance with such rules, as the Compensation Committee shall determine in its discretion. Dividends are paid on vested DERs only to the extent of ordinary income and DERs are not entitled to distributions representing a return of capital. Dividends paid on the Companys DERs are charged to stockholders equity when declared. At September 30, 2007, the Company had 960,750 DERs outstanding, all of which were vested.

(b) Employment Agreements

The Company has an employment agreement with each of its five senior officers, with varying terms that provide for, among other things, base salary, bonuses and change-in-control provisions that are subject to the occurrence of certain triggering events.

(c) Deferred Compensation Plans

The Company administers the MFA Mortgage Investments, Inc. 2003 Non-employee Directors Deferred Compensation Plan and the MFA Mortgage Investments, Inc. Senior Officers Deferred Bonus Plan (collectively, the Deferred Plans). Pursuant to the Deferred Plans, directors and senior officers of the Company may elect to defer a certain percentage of their compensation. The Deferred Plans are intended to provide non-employee directors and senior officers of the Company with an opportunity to defer up to 100% of certain compensation, as defined in the Deferred Plans, while at the same time aligning their interests with the interests of the Companys stockholders. Amounts deferred are considered to be converted into stock units of the Company, which do not represent stock of the Company, but rather the right to receive a cash payment equal to the fair market value of an equivalent number of shares of the common stock. Deferred accounts increase or decrease in value as would equivalent shares of the Companys common stock and are settled in cash at the termination of the deferral period, based on the value of the stock units at that time. The Deferred Plans are non-qualified plans under the Employee Retirement Income Security Act and are not funded. Prior to the time that the deferred accounts are settled, participants are unsecured creditors of the Company. Effective January 1, 2007, the Board resolved to suspend indefinitely the directors ability to defer additional compensation under the MFA Mortgage Investments, Inc. 2003 Non-employee Directors Deferred Compensation Plan.

The following table presents income deferred by participants of the Deferred Plans through September 30, 2007 and the Companys liability under such plans based on the market value of deferred units at September 30, 2007 and December 31, 2006.

Officers deferred		282		300		282		277
Total	$	833	$	941	$	833	$	871

(d) Savings Plan

The Company sponsors a tax-qualified employee savings plan (the Savings Plan) in accordance with Section 401(k) of the Code. Eligible employees of the Company are able to make tax deferred contributions to the Savings Plan, subject to limitations under applicable law. Participants accounts are self-directed and the Company bears all costs associated with administering the Savings Plan. The Company matches 100% of the first 3% of eligible compensation deferred by employees and 50% of the next 2%, subject to a maximum as provided by the Code. Subject to certain restrictions, all of the Companys employees are eligible to participate in the Savings Plan. The Company has elected to operate the Savings Plan under the applicable safe harbor provisions of the Code, whereby among other things, the Company must make contributions for all eligible employees and all matches contributed by the Company immediately vest 100%. For the three months ended September 30, 2007 and 2006, the Company recognized expenses for matching contributions of $25,000 and $23,000, respectively, and $75,000 and $68,000 for the nine months ended September 30, 2007 and 2006, respectively.

GENERAL

Our Business

We are a self-advised REIT primarily engaged in the business of investing, on a leveraged basis, in ARM-MBS. Our MBS portfolio consists primarily of securities that are either (i) issued or guaranteed by a federally chartered corporation, such as Fannie Mae or Freddie Mac, or an agency of the U.S. government, such as Ginnie Mae, or (ii) rated in one of the two highest rating categories by at least one nationally recognized rating agency. Our operating policies also permit us to invest in direct or indirect investments in: (i) other types of MBS; (ii) residential mortgage loans; (iii) collateralized debt obligations and other related securities; (iv) real estate; (v) securities issued by REITs, limited partnerships and closed-end funds; (vi) high-yield corporate securities and other fixed income instruments (corporate or government); and (vii) other types of assets approved by the Board or a committee thereof. Our principal business objective is to generate net income for distribution to our stockholders resulting from the spread between the interest and other income we earn on our investments and the interest expense we pay on the borrowings that we use to finance our investments and our operating costs.

We have elected to be taxed as a REIT for U.S. federal income tax purposes. One of the requirements of maintaining our qualification as a REIT is that we must distribute at least 90% of our annual taxable net income to our stockholders, subject to certain adjustments.

The results of our business operations are affected by a number of factors and primarily depend on, among other things, the level of our net interest income, the market value of our assets and the supply of, and demand for, MBS in the market place. Our net interest income varies primarily as a result of changes in interest rates, the slope of the yield curve, borrowing costs (i.e., interest expense) and prepayment speeds on our MBS portfolio, the behavior of which involves various risks and uncertainties. Interest rates and prepayment speeds, as measured by the constant prepayment rate (or CPR), vary according to the type of investment, conditions in the financial markets, competition and other factors, none of which can be predicted with any certainty. With respect to our business operations, increases in interest rates, in general, may over time cause: (i) the interest expense associated with our borrowings (i.e., repurchase agreements) to increase; (ii) the value of our MBS portfolio and, correspondingly, our stockholders

equity to decline; (iii) prepayments on our MBS portfolio to slow, thereby slowing the amortization of MBS purchase premiums; (iv) coupons on our MBS to reset, although on a delayed basis, to higher interest rates; and (v) the value of our Swaps and, correspondingly, our stockholders equity to increase. Conversely, decreases in interest rates, in general, may over time cause: (i) prepayments on our MBS portfolio to increase, thereby accelerating the amortization of MBS purchase premiums; (ii) coupons on our MBS assets to reset, although on a delayed basis, to lower interest rates; (iii) the interest expense associated with our borrowings to decrease; (iv) the value of our MBS portfolio and, correspondingly, our stockholders equity to increase; and (v) the value of our Swaps and, correspondingly, our stockholders equity to decrease. In addition, our borrowing costs and credit lines are further affected by our perceived credit worthiness.

Although we primarily invest in Agency and AAA rated ARM-MBS; pursuant to our operating policies, we may also acquire fixed rate MBS and/or other investment securities of lower credit quality. At September 30, 2007, we had $11.1 million invested in securities that were rated below AAA or unrated. At September 30, 2007, 99.6% of our assets consisted of Agency MBS, AAA-rated MBS, MBS-related receivables and cash.

The adjustable-rate mortgage loans (or ARMs) collateralizing our MBS are comprised of hybrid mortgage loans, which have interest rates that are fixed for a specified period (typically three to ten years) and, thereafter, generally adjust annually to an increment over a specified interest rate index and, to a lesser extent, ARMs, which have interest rates that generally adjust annually (although some may adjust more frequently) to an increment over a specified interest rate index.

It is our business strategy to hold our investment securities, primarily comprised of MBS, as long-term investments. As such, on at least a quarterly basis, we assess both our ability and intent to continue to hold each of our investment securities. As part of this process, we monitor our investment securities for other-than-temporary impairment. A change in our ability and/or intent to continue to hold any of our investment securities could result in our recognizing an impairment charge or realizing losses upon the sale of such securities. At September 30, 2007, we had gross unrealized losses of $26.1 million and gross unrealized gains of $10.0 million on our investment securities portfolio.

We rely primarily on borrowings under repurchase agreements to finance the acquisition of MBS which have longer-term contractual maturities. Even though most of our MBS have interest rates that adjust over time based on short-term changes in corresponding interest rate indices, typically following an initial fixed-rate period, the interest we pay on our borrowings may increase at a faster pace than the interest we earn on our MBS. In order to reduce this interest rate risk exposure, we enter into derivative financial instruments, which were comprised entirely of Swaps at September 30, 2007. Our Swaps, which are an integral component of our financing strategy, are designated as cash-flow hedges against a portion of our current and anticipated LIBOR-based repurchase agreements. Our Swaps are expected to result in interest savings in a rising interest rate environment; and, conversely, in a declining interest rate environment result in us paying the stated fixed swap rate on each of our instruments, which could be higher than the market rate.

During the nine months ended September 30, 2007, we entered into 64 new Swaps with an aggregate notional amount of $2.279 billion, which had a weighted average fixed pay rate of 5.01%, had Swaps with an aggregate notional amount of $584.7 million expire, and terminated six Swaps with an aggregate notional amount of $305.2 million realizing a net loss of $384,000. We paid a weighted average fixed rate of 5.00% on our Swaps and received a variable rate of 5.35% during the nine months ended September 30, 2007. Our Swaps resulted in a net reduction of interest expense of $6.3 million, or 14 basis points, for the nine months ended September 30, 2007. During the nine months ended September 30, 2007, we received payments of approximately $327,000 on our Caps and recognized $278,000 of Cap premium amortization. During the nine months ended September 30, 2007, we did not purchase any Caps and had Caps with $150.0 million notional amount expire. We had no Caps remaining at September 30, 2007.

Through wholly-owned subsidiaries, we provide third-party investment advisory services which generates fee income. In addition, we will continue to explore alternative business strategies, investments and financing sources and other strategic initiatives, including, but not limited to, the expansion of third-party advisory services, the creation of new investment vehicles to manage, the creation or acquisition of a mortgage origination platform, the acquisition and securitization of ARMs and the creation and/or acquisition of a third-party asset management business to complement our core business strategy of investing, on a leveraged basis, in high quality ARM-MBS. However, no assurance can be provided that any such strategic initiatives will or will not be implemented in the future or, if undertaken, that any such strategic initiatives will favorably impact us.

Impact of Market Conditions

During 2007, concerns about increased subprime mortgage delinquencies led investors to question the underlying risk and value of certain subprime and related collateralized debt obligation (or CDOs) securities across the ratings spectrum. This uncertainty spread to impact investors risk assessment of a wide range of MBS and CDOs. In the third quarter of 2007, this significantly impacted issuers of asset-backed commercial paper (or ABCP), as money market funds and other investors curtailed their investment in certain types of ABCP due to continuing concerns about underlying asset values and future liquidity. As a result of certain issuers being unable to place (or roll) these types of ABCP, there was a significant increase in forced sales of MBS and other securities which further negatively impacted the market value of these assets. As a result, continuing concerns about the ABCP market and its participants and commitments to leveraged private equity transactions have caused many investment banks and other lenders to be more cautious in providing financing through repurchase agreements and have impacted the amount, term and margin requirements associated with these types of financings.

Primarily in response to market conditions during the third quarter of 2007, we selectively sold $650.4 million of Agency and AAA rated MBS at a loss of $22.0 million, with $11.8 million of such net loss previously reflected in the carrying value of these assets at June 30, 2007. As a result of these sales, we (i) decreased the size of our non-Agency MBS portfolio by approximately one-third (or $279.7 million) and (ii) positively impacted spreads earned on our MBS portfolio and future earnings by disposing of lower-yielding Agency MBS acquired prior to 2006 that were negatively impacting net interest income. The Agency MBS sold generated an average yield of 4.3% during the second quarter of 2007 and had coupons that were not scheduled to reset during the 12 months following their sales. In addition, during the quarter ended September 30, 2007, we purchased $937.7 million of Agency MBS and committed to purchase Agency MBS which settled in October 2007 at an aggregate purchase price of $152.0 million. These sales and purchase transactions positively impacted our portfolio yield and increased our concentration in Agency MBS.

The interest rates for most of our adjustable-rate assets are primarily dependent on LIBOR, the one-year constant maturity treasury (or CMT) rate or the 12-month CMT moving average (or MTA). At September 30, 2007, we had (i) approximately $5.481 billion of MBS in our portfolio that were acquired during 2006 and 2007, which had an average yield during the quarter of 5.8%, (ii) approximately $432.7 million of MBS, indexed to MTA, that were acquired prior to 2006, which had an average yield during the quarter of approximately 5.7%, and (iii) approximately $888.4 million of MBS, indexed to CMT, LIBOR and the 11^th District Cost of Funds Index (or COFI), that were acquired prior to 2006, which had an average yield during the quarter of approximately 4.6%.

During the latter part of the third quarter of 2007, spreads on MBS, relative to our cost of funding, widened due to the market conditions described above. Taking advantage of these market conditions, we invested in hybrid Agency MBS with longer initial fixed rate periods, ranging from seven to ten years (i.e., 7/1s to 10/1s).

On September 12, 2007, we completed a public offering of 12,650,000 shares of our common stock, generating cash proceeds of approximately $86.9 million after the payment of underwriting discounts and commissions and expenses incurred in connection with the offering. We deployed the proceeds from this offering on a leveraged basis, purchasing $624.7 million of Agency MBS in September 2007. At September 30, 2007, our MBS portfolio was $6.875 billion, compared to $6.994 billion at June 30, 2007 and $6.341 billion at December 31, 2006. Our leverage ratio, as measured by debt-to-equity, was 8.3 to 1 at September 30, 2007 reflecting the net impact of our sales and purchases of MBS during the third quarter of 2007. (See Notes 12(b) and 12(c) to the consolidated financial statements, included under Item 1.)

The following table presents information regarding our leverage ratios as of the dates presented.

Date				Leverage Ratio (1)
September 30, 2007				8.3 to 1
June 30, 2007				9.1 to 1
March 31, 2007				8.3 to 1
December 31, 2006				8.4 to 1
September 30, 2006				5.9 to 1

(1) As measured by debt to equity.

We expect that over time ARM-MBS experience higher prepayment rates than do fixed-rate MBS, as we believe that homeowners with adjustable-rate and hybrid mortgages exhibit more rapid housing turnover levels or refinancing activity compared to fixed-rate borrowers. In addition, we anticipate that prepayments on ARM-MBS accelerate significantly as the coupon reset date approaches. Over the last eight quarters, ending with September 30, 2007, the CPR on our MBS portfolio has ranged from a low of 18.1%, which was experienced during the third quarter of 2007, to a high of 31.2%, with an average quarterly CPR of 24.7%. We have experienced CPRs trending down over the last two quarters ended September 30, 2007. We expect that our prepayment rates will remain at lower levels in the near-term reflecting our increased investments in 7/1 and 10/1 MBS, which have longer fixed-rate periods, weakness in the housing market and the tightening of underwriting standards on mortgage loans. As of September 30, 2007, assuming a 20% CPR, approximately 35.0% of our MBS assets were expected to reset or prepay during the next 12 months, with a total of 86.6% expected to reset or prepay during the next 60 months, with an average time period until our assets prepay or reset of approximately 30 months. At September 30, 2007, assuming a 20% CPR, the average time period until our assets prepay or reset was approximately 30 months. Our repurchase agreements, extended on average approximately 20 months, reflecting the impact of Swaps, resulting in an asset/liability mismatch of approximately ten months at September 30, 2007.

RESULTS OF OPERATIONS

Quarter Ended September 30, 2007 Compared to the Quarter Ended September 30, 2006

For the third quarter of 2007, we had a net loss of $12.5 million, or $(0.15) per common share, which was significantly impacted by losses of $22.0 million realized on sales of MBS. For the third quarter of 2006, we had net income of $5.0 million, or $0.06 per common share.

Our interest income for the third quarter of 2007 increased by $49.2 million, or 103.5%, to $96.7 million compared to $47.5 million for the third quarter of 2006. This increase in interest income was primarily attributable to the increase in interest income earned on our MBS portfolio, reflecting the growth of our MBS portfolio as well as the increase in the yield earned on our MBS. Excluding changes in market values, we increased our average MBS portfolio by $2.953 billion, or 75.7%, to $6.853 billion for the third quarter of 2007 from $3.900 billion for the third quarter of 2006. The net yield earned on our MBS portfolio increased by 75 basis points to 5.58% for the third quarter of 2007, from 4.83% for the third quarter of 2006, reflecting the increase in market interest rates. The increase in the net yield earned on our MBS portfolio primarily reflects a 38 basis point increase in the gross yield on the MBS portfolio to 6.12% for the third quarter of 2007 from 5.74% for the third quarter of 2006 and a 32 basis point reduction in the cost of net premium amortization to 38 basis points for the third quarter of 2007 from 70 basis points for the third quarter of 2006. The decrease in the cost of our premium amortization during the third quarter of 2007 reflects the decrease in the CPR experienced on our portfolio and the decrease in the average purchase premium on our MBS portfolio. For the third quarter of 2007, our CPR was 18.1% compared to a CPR of 26.4% for the third quarter of 2006. We had a net purchase premium as a percentage of the current face (or par value) of our MBS of 1.2% and 1.8% at September 30, 2007 and September 30, 2006, respectively.

The following table presents the components of the net yield earned on our MBS portfolio for the quarterly periods presented:

Quarter Ended
September 30, 2007	6.12	%	(0.38	)%	(0.16	)%	5.58	%
June 30, 2007	6.09		(0.50	)	(0.19	)	5.40

December 31, 2006	6.04		(0.64	)	(0.22	)	5.18
September 30, 2006	5.74		(0.70	)	(0.21	)	4.83

Interest income from our cash investments, comprised of investments in high quality money market accounts, increased by $655,000 to $1.1 million for the third quarter of 2007 from $471,000 for the third quarter of 2006. Our cash investments yielded 4.96% for the third quarter of 2007 compared to 4.76% for the third quarter of 2006, reflecting market increases in short-term interest rates. Our average cash investment increased to $90.0 million for the third quarter of 2007 compared to $39.2 million for the third quarter of 2006. In general, we manage our cash

relative to our investing, financing, operating requirements, investment opportunities, current and anticipated market conditions and expectations.

Our interest expense for the third quarter of 2007 increased by 114.1% to $81.8 million, from $38.2 million for the third quarter of 2006, reflecting an increase in the amount of, and rate paid on, our borrowings. Our average liability under repurchase agreements for the third quarter of 2007 increased by $2.980 billion, or 91.8%, to $6.226 billion, from $3.246 billion for the third quarter of 2006, reflecting an increase in our leverage and our leveraging of new equity capital as we grew our MBS portfolio. Net of the impact of our Swaps, we experienced a 54 basis point increase in the cost of our borrowings to 5.21% for the third quarter of 2007, from 4.67% for the third quarter of 2006, reflecting the increase in market interest rates. Our Hedging Instruments decreased the cost of our borrowings by $2.5 million, or 16 basis points, during the third quarter of 2007 and $1.6 million, or 19 basis points, for the third quarter of 2006. (See Notes 2(l) and 4 to the accompanying consolidated financial statements, included under Item 1.)

The following table presents certain quarterly information about our average interest-earning assets and interest- bearing liabilities, interest income and expense, asset yields, cost of funds and net interest income for the quarters presented.

(1) Unrealized gains and loses are not reflected in the average amortized cost of MBS.

For the quarter ended September 30, 2007, our net interest income increased by $5.6 million, or 59.8%, to $14.9 million, from $9.3 million for the quarter ended September 30, 2006. This increase can be attributed primarily to the higher yield earned on our assets, an increase in our leverage and an increase in our spread for the third quarter of 2007 compared to the third quarter of 2006.

The following table presents quarterly information regarding our net interest spread and net interest margin (which is net interest income divided by interest-earning assets) for the quarters presented.

For the quarter ended September 30, 2007, we had net other operating losses of $22.1 million compared to net other operating income of $569,000 for the quarter ended September 30, 2006. As previously discussed, in August 2007, we sold $601.1 million of Agency and AAA rated MBS realizing aggregate losses of $21.5 million. Our other operating income for the third quarter of 2006 included a gross gain of $36,000 realized on the $20.3 million sale of a MBS. Our revenue from operations of real estate and miscellaneous other income, which is primarily comprised of advisory fees, are not expected to be material to our future results of operations.

For the third quarter of 2007, we had operating and other expense of $3.5 million, including real estate operating expenses and mortgage interest totaling $451,000 attributable to our one remaining real estate investment. For the third quarter of 2007, our non-real estate related overhead, comprised of compensation and benefits and other general and administrative expense, was $3.1 million, or 0.20% of average assets, compared to $2.4 million, or 0.24% of average assets, for the third quarter of 2006. Our expenses as a percentage of our average assets decreased, as we increased our average assets by leveraging our existing and new equity capital. The cost of our

compensation and benefits increased by $373,000 for the third quarter of 2007 compared to the third quarter of 2006, reflecting an increase in our compensation expense and the cost of our additional hires. Other general and administrative expenses, which were $1.2 million for the third quarter of 2007 compared to $942,000 for the third quarter of 2006, were comprised primarily of the cost of professional services, including auditing and legal fees, costs of complying with the provisions of the Sarbanes-Oxley Act of 2002, corporate insurance, office rent, Board fees and miscellaneous other operating overhead. Our other general and administrative expense for the third quarter of 2007 primarily reflects the cost of our additional office space and the renewal our existing leases at our headquarters at current market rates and an increase in our Board fees.

During the quarter ended September 30, 2007, we recognized income of $257,000 related to a reduction of the $1.8 million of built-in gains tax recognized on the sale of Greenhouse during 2006. For the quarter ended September 30, 2006, the net loss of $1,000 from discontinued operations reflects the reclassification of the net results of operations for Cameron, which was sold during the fourth quarter of 2006. (See Note 2(g) to the accompanying consolidated financial statements, included under Item 1.)

Nine-Month Period Ended September 30, 2007 Compared to the Nine-Month Period Ended September 30, 2006

For the nine months ended September 30, 2007, we had net income available to our common stockholders of $3.5 million, or $0.04 per common share. Our results for the nine months ended September 30, 2007 were significantly impacted by losses of $22.1 million realized on sales of MBS. For the nine months ended September 30, 2006, we had a net loss of $3.8 million, or $(0.05) per common share, which was significantly impacted by net losses of $23.1 million realized on the sale of MBS and $4.6 million of income from discontinued operations.

Our interest income for the nine months ended September 30, 2007 increased by $124.8 million, or 84.5%, to $272.5 million compared to $147.7 million earned during the first nine months of 2006. This increase in interest income is primarily attributable to the increase in interest income earned on our MBS portfolio, reflecting the growth of our MBS portfolio as well as the increase in the yield earned on our MBS. Excluding changes in market values, we increased our average MBS portfolio by $2.119 billion, or 47.1%, to $6.619 billion for the first nine months of 2007 from $4.500 billion for the first nine months of 2006. The net yield earned on our MBS portfolio increased by 111 basis points, to 5.44% for the first nine months of 2007 from 4.33% for the first nine months of 2006. The increase in the net yield earned on our MBS primarily reflects an 89 basis point increase in the gross yield on the MBS portfolio to 6.11% for the first nine months of 2007 from 5.22% for the first nine months of 2006 and, a 22 basis point reduction in the cost of net premium amortization to 48 basis points for the first nine months of 2007 from 70 basis points for the comparable 2006 period. The decrease in the cost of our premium amortization during the first nine months of 2007 reflects the decrease in the CPR experienced on our portfolio and the decrease in the average purchase premium on our MBS portfolio. For the nine months ended September 30, 2007 our CPR was 21.4% compared to a CPR of 25.5% for the first nine months of 2006.

Interest income from our cash investments, comprised of investments in high quality money market accounts, increased by $531,000 to $2.2 million for the first nine months of 2007 from $1.7 million for the first nine months of 2006. Our cash investments yielded 5.03% for the first nine months of 2007, compared to 4.56% for first nine months of 2006, reflecting market increases in short-term interest rates. Our average cash investments increased to $58.7 million for the first nine months of 2007 compared to $49.1 million for the first nine months of 2006. In general, we manage our cash investments relative to our investing, financing, operating requirements, investment opportunities, current and anticipated market conditions and expectations.

Our interest expense for the first nine months of 2007 increased by 94.0% to $232.4 million, from $119.8 million for the first nine months of 2006, reflecting an increase in the amount of, and rate paid on, our borrowings. Our average liability under repurchase agreements for the first nine months of 2007 increased by $2.141 billion, or 55.8%, to $5.977 billion, from $3.836 billion for the first nine months of 2006, reflecting an increase in our leverage and leveraging of new equity capital as we grew our investment portfolio. Net of the impact of our Hedging Instruments, we experienced a 102 basis point increase in the cost of our borrowings to 5.20% for the first nine months of 2007, from 4.18% for the first nine months of 2006, reflecting the increase in market interest rates. Our Hedging Instruments decreased the cost of our repurchase agreements by $6.4 million, or 14 basis points, during the first nine months of 2007 and decreased the cost of our repurchase agreements by $4.1 million, or 14 basis points, during the first nine months of 2006. (See Notes 2(l) and 4 to the accompanying consolidated financial statements, included under Item 1.)

For the nine months ended September 30, 2007, our net interest income increased by $12.2 million, or 43.8%, to $40.1 million, from $27.9 million for the nine months ended September 30, 2006. This increase can be attributed primarily to the higher yield earned on our assets before the impact of leverage, an increase in our leverage and the improvement to our spread for the first nine months of 2007 compared to the first nine months of 2006. Our net interest spread and margin were 0.24% and 0.79%, respectively, for the nine months ended September 30, 2007, compared to 0.15% and 0.81%, respectively, for the first nine months of 2006.

For the first nine months of 2007, we had a net other loss of $21.0 million compared to a net other loss of $21.4 million for the first nine months of 2006. Our net other loss for both periods were primarily comprised of losses realized on sales of MBS. During the first nine months of 2007, we realized losses of $22.1 million on the sale of MBS, of which $22.0 million were incurred during the third quarter of 2007 primarily as a result of sales of Agency and AAA rated MBS made to increase our liquidity position in response to the disruption in the credit markets. Our net other loss for the first nine months of 2006 was comprised primarily of a net loss of $23.1 million on sales of MBS, as a result of the repositioning of our MBS portfolio.

Our one remaining real estate investment generated revenue of approximately $1.2 million for each of the first nine months of 2007 and 2006. In addition, we earned $328,000 and $600,000 in advisory fees during the nine months ended September 30, 2007 and 2006, respectively, which are included in miscellaneous other income, net. Our revenue from operations of real estate and advisory fees are not expected to be material to our future results of operations. (See Note 5b to the accompanying consolidated financial statements, included under Item 1.)

During the first nine months of 2007, we had operating and other expense of $9.8 million, which included real estate operating expenses and mortgage interest totaling $1.3 million attributable to our one remaining real estate investment. Our non-real estate related overhead, comprised of compensation and benefits and other general and administrative expense, was $8.5 million, or 0.17% of average assets for the first nine months of 2007, compared to $7.6 million, or 0.22% of average assets, for the first nine months of 2006. Our expenses as a percentage of our average assets decreased, as we increased our average assets by leveraging our existing and new equity capital during the first nine months of 2007. The cost of our compensation and benefits increased by $306,000 for the first nine months of 2007 compared to the first nine months of 2006, reflecting an increase in our compensation expense, and our additional hires. Our other general and administrative expenses for the nine months ended September 30, 2007, are comprised primarily of the cost of professional services, including auditing and legal fees, costs of complying with the provisions of the Sarbanes-Oxley Act of 2002, corporate insurance, office rent, Board fees and miscellaneous other operating costs. The increase in our other general and administrative expense for the first nine months of 2007 to $3.7 million from $3.0 million for the first nine months of 2006, reflects the cost of our additional office space and the renewal our existing leases at our headquarters at current market rates commencing with the second quarter of 2007 and an increase in our Board fees.

For the first nine months of 2007, we recognized $257,000 of income related to a reduction of the $1.8 million built-in-gains tax of recognized on the sale of Greenhouse during 2006. For the first nine months of 2006, we reported income of $4.6 million from discontinued operations, or $0.06 per common share, which was primarily comprised the first quarter gain of $4.7 million on the sale of Greenhouse, and a net loss of $134,000 from the operations for Greenhouse and Cameron on a net basis. (See Note 2(g) to the accompanying consolidated financial statements, included under Item 1.)

LIQUIDITY AND CAPITAL RESOURCES

Our principal sources of cash generally consist of borrowings under repurchase agreements, payments of principal and interest we receive on our MBS portfolio and, depending on market opportunities, proceeds from capital market transactions. We use significant cash to repay principal and interest on our repurchase agreements, purchase MBS, make dividend payments on our capital stock, fund our operations and to make other investments that we consider appropriate. In addition, based upon market conditions, we may use cash to repurchase shares of our common stock pursuant to our Repurchase Program.

We employ a diverse capital raising strategy under which we may issue capital stock. On September 12, 2007, we completed a public offering of 12,650,000 shares of our common stock and received net proceeds of approximately $86.9 million after the payment of underwriting discounts and commissions and expenses. In addition, during the first nine months of 2007, we issued 3,206,000 shares of common stock pursuant to our CEO Program raising net proceeds of $23,891,416 and 12,027 shares of common stock pursuant to our DRSPP raising net proceeds of $86,963. At September 30, 2007, we had an aggregate of $125,159,022 available under our two

effective shelf registration statements on Form S-3 and 9,502,156 shares of common stock remained available for issuance pursuant to our DRSPP shelf registration.

On October 5, 2007, we completed our second public offering of 2007, issuing 8,050,000 shares of common stock and received net proceeds of approximately $60.2 million after the payment of underwriting discounts and commissions and expenses. We intend to use the net proceeds from this offering to acquire additional high quality MBS, on a leveraged basis, consistent with our investment policy and for working capital, which may include, among other things, the repayment of our repurchase agreements.

To the extent we raise additional equity capital from future capital market transactions, we currently anticipate using the net proceeds to purchase additional MBS or other securities, to make scheduled payments of principal and interest on our repurchase agreements and for other general corporate purposes. We may also acquire additional interests in residential ARMs and/or other investments consistent with our investment strategies and operating policies. 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.

While we generally intend to hold our MBS as long-term investments, certain MBS may be sold in order to manage our interest rate risk and liquidity needs, meet other operating objectives and adapt to market conditions. As such, all of our MBS are designated as available-for-sale. The timing and impact of future sales of MBS, if any, cannot be predicted with any certainty. During the nine months ended September 30, 2007, we sold 30 MBS, generating net proceeds of $705.7 million. We received cash of $1.384 billion from prepayments and scheduled amortization on our investment securities during the first nine months of 2007. Since our MBS are generally financed with repurchase agreements, a significant portion of the proceeds from our MBS sales, prepayments and scheduled amortization were used to repay balances under our repurchase agreements. During the nine months ended September 30, 2007, we purchased $2.656 billion of investment securities, primarily comprised of ARM-MBS, using proceeds from repurchase agreements, existing cash and cash proceeds generated from the equity raised through the public sale of our common stock.

During the month ended October 31, 2007, we purchased $819.3 million of MBS (of which $152.0 million were committed to in September 2007) and committed to purchase approximately $60.0 million which are scheduled to settle in November 2007.

Borrowings under our repurchase agreements were $6.314 billion at September 30, 2007 compared to $5.723 billion at December 31, 2006. At September 30, 2007, we continued to have available capacity under our repurchase agreement credit limits. At September 30, 2007, our repurchase agreements had a weighted average borrowing rate of 5.13%, on loan balances of between $550,000 and $137.5 million.

During the nine months ended September 30, 2007, we paid cash dividends of $6.1 million on our preferred stock and $19.0 million on our common stock. On October 1, 2007, we declared a dividend of $0.10 per share on our common stock for the third quarter of 2007. This dividend, which in the aggregate totaled $10.6 million, was paid on October 31, 2007 to stockholders of record as of October 12, 2007.

Under our repurchase agreements we pledge additional assets as collateral to our repurchase agreement counterparties (i.e., lenders) when the estimated fair value of the existing pledged collateral under such agreements declines and such lenders demand additional collateral (i.e., a margin call). Margin calls result from a decline in the value of the MBS collateralizing our repurchase agreements, generally following the monthly principal reduction of such MBS due to scheduled amortization and prepayments on the underlying mortgages, changes in market interest rates, a decline in market prices and other market factors. To cover a margin call, we may pledge additional securities or cash. Cash held on deposit as collateral with lenders, if any, is reported on our balance sheet as restricted cash. At the time one of our repurchase agreement matures, any restricted cash on deposit is generally applied against the repurchase agreement balance, thereby reducing the amount borrowed. Through September 30, 2007, we satisfied all of our margin calls with either cash or an additional pledge of MBS collateral. At September 30, 2007, we had MBS with a fair value of $205.5 million that were not pledged as collateral and $206.4 million of unrestricted cash. We believe that we have adequate financial resources to meet our obligations, including margin calls, as they come due, to fund dividends we declare and to actively pursue our investment strategies. However, should the value of our MBS suddenly decrease, significant margin calls on our repurchase agreements could result, causing an adverse change in our liquidity position.

INFLATION

Substantially all of our assets and liabilities are financial in nature. As a result, changes in interest rates and other factors impact our performance far more than does inflation. Our financial statements are prepared in accordance with GAAP and dividends are based upon net income as calculated for tax purposes; in each case, our results of operations and reported assets, liabilities and equity are measured with reference to historical cost or fair market value without considering inflation.

OTHER MATTERS

We intend to conduct our business so as to maintain our exempt status under, and not to become regulated as an investment company for purposes of, the Investment Company Act of 1940, as amended (or the Investment Company Act). If we failed to maintain our exempt status under the Investment Company Act and became regulated as an investment company, our ability to, among other things, use leverage would be substantially reduced and, as a result, we would be unable to conduct our business as described in our annual report on Form 10-K for the year ended December 31, 2006 and this quarterly report on Form 10-Q for the quarter ended September 30, 2007. The Investment Company Act exempts entities that are primarily engaged in the business of purchasing or otherwise acquiring mortgages and other liens on and interests in real estate (or Qualifying Interests). Under the current interpretation of the staff of the SEC, in order to qualify for this exemption, we must maintain (i) at least 55% of our assets in Qualifying Interests (or the 55% Test) and (ii) at least 80% of our assets in real estate related assets (including Qualifying Interests) (or the 80% Test). MBS that do not represent all of the certificates issued (i.e., an undivided interest) with respect to the entire pool of mortgages (i.e., a whole pool) underlying such MBS may be treated as securities separate from such underlying mortgage loans and, thus, may not be considered Qualifying Interests for purposes of the 55% Test; however, such MBS would be considered real estate related assets for purposes of the 80% Test. Therefore, for purposes of the 55% Test, our ownership of these types of MBS is limited by the provisions of the Investment Company Act. In meeting the 55% Test, we treat as Qualifying Interests those MBS issued with respect to an underlying pool as to which we own all of the issued certificates. If the SEC or its staff were to adopt a contrary interpretation, we could be required to sell a substantial amount of our MBS under potentially adverse market conditions. Further, in order to insure that at all times we qualify for this exemption from the Investment Company Act, we may be precluded from acquiring MBS whose yield is higher than the yield on MBS that could be otherwise purchased in a manner consistent with this exemption. Accordingly, we monitor our compliance with both of the 55% Test and the 80% Test in order to maintain our exempt status under the Investment Company Act. As of September 30, 2007, we determined that we were in and had maintained compliance with both the 55% Test and the 80% Test.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We seek to manage our risks related to interest rates, liquidity, prepayment speeds, market value and the credit quality of our assets while, at the same time, seeking to provide an opportunity to stockholders to realize attractive total returns through ownership of our capital stock. While we do not seek to avoid risk, we seek to: assume risk that can be quantified from historical experience, and actively manage such risk; earn sufficient returns to justify the taking of such risks; and, maintain capital levels consistent with the risks that we undertake.

INTEREST RATE RISK

We primarily invest in ARM-MBS on a leveraged basis. We take into account both anticipated coupon resets and expected prepayments when measuring the sensitivity of our ARM-MBS portfolio to changes in interest rates. In measuring our assets-to-borrowings repricing gap (or Repricing Gap), we measure the difference between: (a) the weighted average months until the next coupon adjustment or projected prepayment on the ARM-MBS portfolio; and (b) the months remaining until our repurchase agreements mature, applying the same projected prepayment rate and including the impact of Swaps. The CPR is applied in order to reflect, to a certain extent, the prepayment characteristics inherent in our interest-earning assets and interest-bearing liabilities. Over the last two years, on a quarterly basis, ending with September 30, 2007, the monthly CPR on our MBS portfolio ranged from a low of 18.1%, which was experienced during the quarter ended September 30, 2007, to a high of 31.2%, with an average quarterly CPR of 24.7%.

The following table presents information at September 30, 2007 about our Repricing Gap based on contractual maturities (i.e., 0 CPR), and applying a 15% CPR, 20% CPR and 25% CPR.

CPR
0% (2)	54	20	34
15%	35	20	15
20%	30	20	10
25%	27	20	7

(1) Reflects the effect of our Hedging Instruments.

(2) Reflects contractual maturities, which does not consider any prepayments.

At September 30, 2007, our financing obligations under repurchase agreements had remaining contractual terms of five years or less, which does not reflect the impact of Swaps. Upon contractual maturity or an interest reset date, these borrowings are refinanced at then prevailing market rates.

The interest rates for most of our adjustable-rate assets are primarily dependent on LIBOR, the CMT rate or the MTA rate, while our debt obligations, in the form of repurchase agreements, are generally priced off of LIBOR. While LIBOR and CMT generally move together, there can be no assurance that such movements will be parallel, such that the magnitude of the movement of one index will match that of the other index. At September 30, 2007, we had 78.0% of our ARM-MBS repricing from LIBOR (of which 64.1% repriced based on 12-month LIBOR and 13.9% repriced based on six-month LIBOR), 14.6% repricing from the one-year CMT index, 6.7% repricing from MTA and 0.7% repricing from COFI.

Our adjustable-rate assets reset on various dates that are not matched to the reset dates on our borrowings (i.e., repurchase agreements). In general, the repricing of our repurchase agreements occurs more quickly than the repricing of our assets. Therefore, on average, our cost of borrowings may rise or fall more quickly in response to changes in market interest rates than does the yield on our interest-earning assets.

The mismatch between repricings or maturities within a time period is commonly referred to as the gap for that period. A positive gap, where repricing of interest-rate sensitive assets exceeds the maturity of interest-rate sensitive liabilities, generally will result in the net interest margin increasing in a rising interest rate environment and decreasing in a falling interest rate environment; conversely, a negative gap, where the repricing of interest rate sensitive liabilities exceeds the repricing of interest-rate sensitive assets will generate opposite results. As presented in the following table, at September 30, 2007, we had a positive gap of $205.7 million in our less than three month category. The following gap analysis is prepared assuming a 20% CPR; however, actual future prepayment speeds could vary significantly. The gap analysis does not reflect the constraints on the repricing of ARM-MBS in a given period resulting from interim and lifetime cap features on these securities, nor the behavior of various indices applicable to our assets and liabilities. The gap methodology does not assess the relative sensitivity of assets and liabilities to changes in interest rates and also fails to account for interest rate caps and floors imbedded in our MBS or include assets and liabilities that are not interest rate sensitive. The notional amount of the Swaps is presented in the following table, as they fix the cost and repricing characteristics of a portion of our repurchase agreements. While the fair value of our Swaps are reflected in our consolidated balance sheets, the notional amounts, presented in the table below, are not.

The following table presents our interest rate risk using the gap methodology applying a 20% CPR on MBS at September 30, 2007.

MARKET VALUE RISK

All of our investment securities are designated as available-for-sale assets. As such, they are reflected at their estimated fair value, with the difference between amortized cost and estimated fair value reflected in accumulated other comprehensive income, a component of stockholders equity. (See Note 10 to the accompanying consolidated financial statements, included under Item 1.) The estimated fair value of our MBS fluctuate primarily due to changes in interest rates and other factors; however, given that, at September 30, 2007, these securities were primarily Agency MBS or AAA rated MBS, such changes in the estimated fair value of our MBS are generally not believed to be credit-related. At September 30, 2007, we held $6.4 million of investment securities that were rated below AAA and $4.7 million of unrated securities. Accordingly, to a limited extent, we are exposed to credit-related market value risk. Generally, in a rising interest rate environment, the estimated fair value of our MBS would be expected to decrease; conversely, in a decreasing interest rate environment, the estimated fair value of such MBS would be expected to increase. If the estimated fair value of our MBS collateralizing our repurchase agreements decreases, we may receive margin calls from our repurchase agreement counterparties for additional MBS collateral or cash due to such decline. In the event that we do not have adequate cash or MBS to meet margin calls, we could apply a strategy of reducing borrowings and assets, by selling assets or not replacing securities as they amortize and/or prepay, thereby shrinking the balance sheet. Such an action would likely reduce our interest income, interest expense and net income, the extent of which would be dependent on the level of reduction in assets and liabilities as well as the sale price of the assets sold. Such a decrease in our net interest income could negatively impact cash available for distributions, which in turn could reduce the market price of our issued and outstanding common stock and preferred stock. Further, if we were unable to meet margin calls, lenders could sell the securities collateralizing our repurchase agreements with such lenders, which sales could result in a loss to us.

LIQUIDITY RISK

The primary liquidity risk for us arises from financing long-maturity assets, which have interim and lifetime interest rate adjustment caps, with shorter-term borrowings in the form of repurchase agreements. Although the interest rate adjustments of these assets and liabilities fall within the guidelines established by our operating policies, maturities are not required to be, nor are they, matched.

Our assets which are pledged to secure repurchase agreements are typically high-quality MBS. At September 30, 2007, we had cash and cash equivalents of $206.4 million and unpledged MBS of $205.5 million available to meet margin calls on our repurchase agreements and for other corporate purposes. However, should the value of our investment securities pledged as collateral suddenly decrease, margin calls relating to our repurchase agreements could increase, causing an adverse change to our liquidity position. As such, we cannot assure that we will always be able to roll over our repurchase agreements.

PREPAYMENT AND REINVESTMENT RISK

Premiums paid on our investment securities are amortized against interest income and discounts are accreted to interest income as we receive principal payments on such securities, reflecting prepayments and scheduled amortization. Premiums arise when we acquire MBS at a price in excess of the principal balance of the mortgages securing such MBS (i.e., par value). Conversely, discounts arise when we acquire MBS at a price below the principal balance of the mortgages securing such MBS. For financial accounting purposes, interest income is accrued based on the outstanding principal balance of the investment securities and their contractual terms. In general, purchase premiums on our investment securities, currently comprised primarily of MBS, are amortized against interest income over the lives of the securities using the effective yield method, adjusted for actual prepayment activity. An increase in the prepayment rate, as measured by the CPR, will typically accelerate the amortization of purchase premiums, thereby reducing the yield/interest income earned on such assets.

For tax accounting purposes, the purchase premiums and discounts are amortized based on the constant effective yield calculated at the purchase date. Therefore, on a tax basis, amortization of premiums and discounts will differ from those reported for financial purposes under GAAP. At September 30, 2007, our net premium for our investment securities portfolio for financial accounting purposes was $83.5 million (1.2% of the principal balance of MBS); while the net premium for income tax purposes was estimated at $81.1 million.

In general, we believe that we will be able to reinvest proceeds from scheduled principal payments and prepayments at acceptable yields; however, no assurances can be given that, should significant prepayments occur, market conditions would be such that acceptable investments could be identified and the proceeds timely reinvested.

The information presented in the following table projects the potential impact of sudden parallel changes in interest rates on net interest income and portfolio value, including the impact of Hedging Instruments, over the next 12 months based on the assets in our investment portfolio on September 30, 2007. We acquire interest-rate sensitive assets and fund them with interest-rate sensitive liabilities. All changes in income and value are measured as the percentage change from the projected net interest income and portfolio value at the base interest rate scenario.

Change in Interest Rates	Percentage Change in Net Interest Income	Percentage Change in Portfolio Value
+1.00%	(10.95%)	(1.17%)
+0.50%	(4.19%)	(0.48%)
(0.50%)	3.66%	0.27%
(1.00%)	5.83%	0.32%

Certain assumptions have been made in connection with the calculation of the information set forth in the above table and, as such, there can be no assurance that assumed events will occur or that other events will not occur that would affect the outcomes. The base interest rate scenario assumes interest rates at September 30, 2007. The analysis presented utilizes assumptions and estimates based on managements judgment and experience. Furthermore, while we generally expect to retain such assets and the associated interest rate risk to maturity, future purchases and sales of assets could materially change our interest rate risk profile. It should be specifically noted that the information set forth in the above table and all related disclosure constitutes forward-looking statements within the meaning of Section 27A of the 1933 Act and Section 21E of the 1934 Act. Actual results could differ significantly from those estimated in the table.

The table quantifies the potential changes in net interest income and portfolio value should interest rates immediately change (or Shock). The table presents the estimated impact of interest rates instantaneously rising 50 and 100 basis points, and falling 50 and 100 basis points. The cash flows associated with the portfolio of MBS for each rate Shock are calculated based on assumptions, including, but not limited to, prepayment speeds, yield on future acquisitions, slope of the yield curve and size of the portfolio. Assumptions made on the interest rate sensitive liabilities, which are assumed to be repurchase agreements, include anticipated interest rates, collateral

requirements as a percent of the repurchase agreement, amount and term of borrowing.

The impact on portfolio value is approximated using the calculated effective duration (i.e., the price sensitivity to changes in interest rates) of 0.74 and expected convexity (i.e., the approximate change in duration relative to the change in interest rates) of (0.85). The impact on net interest income is driven mainly by the difference between portfolio yield and cost of funding of our repurchase agreements, which includes the cost and/or benefit from Hedging Instruments that hedge certain of our repurchase agreements. Our asset/liability structure is generally such that an increase in interest rates would be expected to result in a decrease in net interest income, as our repurchase agreements are generally shorter term than our interest-earning assets. When interest rates are Shocked, prepayment assumptions are adjusted based on managements expectations along with the results from the prepayment model.

Item 4. Controls and Procedures

Our management, including our Chief Executive Officer (or CEO) and Chief Financial Officer (or CFO), reviewed and evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the 1934 Act) as of the end of the period covered by this quarterly report. Based on that review and evaluation, the CEO and CFO concluded that our current disclosure controls and procedures, as designed and implemented, were effective. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in our periodic reports.

There have been no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
