REDWOOD TRUST, INC. AND SUBSIDIARIES
NOTES TO FINANCIAL STATEMENTS
September 30, 2006
(Unaudited)
NOTE 1.  REDWOOD TRUST
Redwood Trust, Inc., together with its subsidiaries (Redwood, we, or us), is a specialty finance company that invests in and manages real estate assets. In general, we invest in real estate assets by acquiring and owning asset-backed securities backed by real estate loans. Our primary focus is credit-enhancing residential and commercial real estate loans. We credit-enhance loans by acquiring and managing the first-loss and other credit-sensitive securities that bear the bulk of the credit risk of securitized loans.
As a real estate investment trust (REIT), we are required to distribute to stockholders as dividends at least 90% of our REIT taxable income, which is our income as calculated for tax purposes, exclusive of income earned in taxable subsidiaries. In order to meet our dividend distribution requirements, we have been paying both a regular quarterly dividend and a year-end special dividend. We expect our special dividend amount to be highly variable and we may not pay a special dividend in every year. Our dividend policies and distribution practices are determined by our Board of Directors and may change over time.
Redwood was incorporated in the State of Maryland on April 11, 1994, and commenced operations on August 19, 1994. Our executive offices are at One Belvedere Place, Suite 300, Mill Valley, California 94941.

References to Sequoia mean Sequoia Mortgage Funding Corporation and Sequoia Residential Funding, Inc. References to Acacia mean all the Acacia CDO entities. References to the Redwood REIT mean Redwood exclusive of its taxable subsidiaries. The taxable subsidiaries of Redwood are Holdings, Holdings’ wholly owned subsidiaries, RMF and RAM, and the Acacia entities. All inter-company balances and transactions have been eliminated in consolidation.
Due diligence expenses are costs for services related to re-underwriting and analyzing the loans we acquire or the loans we credit-enhance through the purchase of certain securities. In previous financial statements we recognized these expenses as a reduction in interest income. After reviewing again the nature of these costs it was determined that they did not directly relate to the specific creation of a securitization and were dependent on specific asset acquisition analysis (which may or may not result in our acquiring assets). Therefore, beginning in the second quarter of 2006, we are recognizing these due diligence costs as an operating expense, and these amounts for prior periods have been reclassified to conform to this presentation.

NOTES TO FINANCIAL STATEMENTS — (Continued)
Use of Estimates
The preparation of financial statements in conformity with Generally Accepted Accounting Principles in the United States of America (GAAP) requires us to make a significant number of estimates in the preparation of financial statements. These include fair value of certain assets, amount and timing of credit losses, prepayment assumptions, and other items that affect the reported amounts of certain assets and liabilities as of the date of the consolidated financial statements and the reported amounts of certain revenues and expenses during the reported period. It is likely that changes in these estimates (e.g., market values due to changes in supply and demand, credit performance, prepayments, interest rates, or other reasons; yields due to changes in credit outlook and loan prepayments) will occur in the near term. Our estimates are inherently subjective in nature and actual results could differ from our estimates and the differences may be material.
Sequoia and Acacia Securitizations
We treat the securitizations we sponsor as financings under the provisions of Statement of Financial Accounting Standards No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities (FAS 140), as under these provisions we have retained effective control over these loans and securities. Control is maintained through our active management of the assets in the securitization entities, our retained asset transfer discretion, our ability to direct certain servicing decisions, or a combination of the foregoing. These securitization entities issue asset-backed securities (ABS) to fund their acquisitions of loans and securities. Accordingly, the underlying loans owned by the Sequoia entities are shown on our Consolidated Balance Sheets under real estate loans and the Sequoia ABS issued to third parties are shown on our Consolidated Balance Sheets under ABS issued. Assets owned by the Acacia entities are shown on our Consolidated Balance Sheets in our real estate securities portfolio. ABS issued by the Acacia entities are shown on our Consolidated Balance Sheets as ABS issued. In our Consolidated Statements of Income, we record interest income on the loans and securities and interest expense on the ABS issued. Any Sequoia ABS (CES, investment grade, or interest-only security (IO)) acquired by Redwood or Acacia from Sequoia entities and any Acacia ABS acquired by Redwood for its own portfolio are eliminated in consolidation and thus are not shown separately on our Consolidated Balance Sheets.
Earning Assets
Earning assets (as consolidated for GAAP purposes) consist primarily of real estate loans and securities. Coupon interest is recognized as revenue when earned according to the terms of the loans and securities and when, in our opinion, it is collectible. Purchase discounts and premiums related to earning assets are amortized into interest income over their estimated lives to generate an effective yield, considering the actual and future estimated prepayments of the assets. Gains or losses on the sale of earning assets are based on the specific identification method.
Real estate loans combine our consolidated residential and commercial real estate loans. Real estate securities combine our consolidated residential and commercial real estate securities including those securities we define as credit-enhancement securities (CES). CES includes below-investment grade securities. Also included in our securities portfolio are residential sub-prime, collateral debt obligation (CDO), home equity lines of credit (HELOCs), and REIT corporate debt securities.
Real Estate Loans: Held-for-Investment
Our consolidated real estate loans are classified as held-for-investment because the consolidated securitization entities that own these assets have the ability and intent to hold these loans to maturity. Real estate loans held-for-investment are carried at their unpaid principal balances adjusted for net unamortized premiums or discounts and net of any allowance for credit losses.
Pursuant to Statement of Financial Accounting Standards No. 91, Accounting for Nonrefundable Fees and Costs Associated with Originating or Acquiring Loans and Initial Direct Cost of Leases (FAS 91), we

9


Table of Contents

REDWOOD TRUST, INC. AND SUBSIDIARIES
NOTES TO FINANCIAL STATEMENTS — (Continued)
use the interest method to determine an effective yield and amortize the premium or discount on loans. For loans acquired prior to July 1, 2004, we use coupon interest rates as they change over time and anticipated principal payments to determine an effective yield to amortize the premium or discount. For loans acquired after July 1, 2004, we use the initial coupon interest rate of the loans (without regard to future changes in the underlying indices) and anticipated principal payments to calculate an effective yield to amortize the premium or discount.
Real Estate Securities: Available-for-Sale
Real estate securities are classified as available-for-sale (AFS) and are carried at their estimated fair values. Cumulative unrealized gains and losses are reported as a component of accumulated other comprehensive income in our Consolidated Statements of Stockholders’ Equity.
When recognizing revenue on AFS securities, we employ the interest method to account for purchase premiums, discounts, and fees associated with these securities. For securities rated AAA or AA, we use the interest method as prescribed under FAS 91, while for securities rated A or lower we use the interest method as prescribed under the Emerging Issues Task Force of the Financial Accounting Standards Board 99-20, Recognition of Interest Income and Impairment on Purchased and Retained Beneficial Interests in Securitized Financial Assets (EITF 99-20). The use of these methods requires us to project cash flows over the remaining life of each asset. These projections include assumptions about interest rates, prepayment rates, the timing and amount of credit losses, and other factors. We review and make adjustments to our cash flow projections on an ongoing basis and monitor these projections based on input and analyses received from external sources, internal models, and our own judgment and experience. There can be no assurance that our assumptions used to estimate future cash flows or the current period’s yield for each asset would not change in the near term.
For determining other-than-temporary impairment on our real estate securities, we use the guidelines prescribed under EITF 99-20, Statement of Financial Accounting Standards No. 115, Accounting for Certain Investments in Debt and Equity Securities (FAS 115), and Staff Accounting Bulletin No. 5(m), Other-Than-Temporary Impairment for Certain Investments in Debt and Equity Securities (SAB 5(m)). Any other-than-temporary impairments are reported under net recognized gains (losses) and valuation adjustments in our Consolidated Statements of Income.
Credit Reserves
For consolidated real estate loans held-for-investment, we establish and maintain credit reserves based on estimates of credit losses inherent in these loan portfolios as of the reporting date. To calculate the credit reserve, we assess inherent losses by determining loss factors (defaults, the timing of defaults, and loss severities upon defaults) that can be specifically applied to each of the consolidated loans, loan pools, or individual loans. We follow the guidelines of Staff Accounting Bulletin No. 102, Selected Loan Loss Allowance Methodology and Documentation (SAB 102), Statement of Financial Accounting Standards No. 5, Accounting for Contingencies (FAS 5), and Statement of Financial Accounting Standards No. 114, Accounting by Creditors for Impairment of a Loan (FAS 114), in setting credit reserves for our real estate loans.
The following factors are considered and applied in such determinations:
•  Ongoing analyses of the pool of loans — including, but not limited to, the age of loans, underwriting standards, business climate, economic conditions, geographical considerations, and other observable data;
 
•  Historical loss rates and past performance of similar loans;
 
•  Relevant environmental factors;
 
•  Relevant market research and publicly available third-party reference loss rates;
 
•  Trends in delinquencies and charge-offs;

10


Table of Contents

REDWOOD TRUST, INC. AND SUBSIDIARIES
NOTES TO FINANCIAL STATEMENTS — (Continued)
•  Effects and changes in credit concentrations;
 
•  Information supporting the borrowers’ ability to meet obligations;
 
•  Ongoing evaluations of fair values of collateral using current appraisals and other valuations; and
 
•  Discounted cash flow analyses.
Once we determine applicable default amounts, the timing of the defaults, and severity of losses upon the defaults, we estimate expected losses for each pool of loans over its expected life. We then estimate the timing of these losses and the losses probable to occur over an effective loss confirmation period. This period is defined as the range of time between the probable occurrence of a credit loss (such as the initial deterioration of the borrower’s financial condition) and the confirmation of that loss (the actual impairment or charge-off of the loan). The losses expected to occur within the estimated loss confirmation period are the basis of our credit reserves because we believe those losses exist as of the reported date of the financial statements. We re-evaluate the level of our credit reserves on at least a quarterly basis, and we record provision, charge-offs, and recoveries monthly.
Additionally, if a loan becomes real estate owned (REO) or is reclassified as held-for-sale, valuations specific to that loan also include analyses of the underlying collateral.
Cash and Cash Equivalents
Cash and cash equivalents include cash on hand and highly liquid investments with original maturities of three months or less.
Other Assets
Restricted Cash
Restricted cash includes principal and interest payments from real estate loans and securities owned by consolidated securitization entities that are collateral for, or payable to, owners of ABS issued by those entities and cash pledged as collateral on interest rate agreements. Restricted cash may also include cash retained in Acacia or Sequoia securitization trusts prior to purchase of real estate loans and securities.
Deferred Tax Assets
Net deferred tax assets represent the net benefit of net operating loss (NOL) carry forwards, real estate asset basis differences, recognized tax gains on whole loan securitizations, interest rate agreement basis differences, and other temporary GAAP and tax timing differences. These temporary timing differences will be recognized in different periods for GAAP and tax purposes. Net unrealized gains and losses on securities and interest rate agreements in our taxable subsidiaries that are reported in other comprehensive income are adjusted for the effects of tax, thus creating deferred tax assets (liabilities).
Deferred Asset-Backed Securities Issuance Costs
Deferred ABS issuance costs are costs associated with the issuance of ABS from securitization entities we sponsor. These costs typically include underwriting, rating agency, legal, accounting, and other fees. Deferred ABS issuance costs are reported on our Consolidated Balance Sheets as deferred charges and are amortized as an adjustment to consolidated interest expense using the interest method based on the actual and estimated repayment schedules of the related ABS issued under the principles prescribed in Accounting Practice Bulletin 21, Interest on Receivables and Payables (APB 21).
Other Assets
Other assets on our Consolidated Balance Sheets include REO, fixed assets, purchased interest, and other prepaid expenses. REO is reported at the lower of cost or market value.

REDWOOD TRUST, INC. AND SUBSIDIARIES
NOTES TO FINANCIAL STATEMENTS — (Continued)
Accrued Interest Receivable and Principal Receivable
Accrued interest receivable and principal receivable represent principal and interest that is due and payable to us. These are generally received within the next month.
Interest Rate Agreements and Purchase Commitments
We enter into interest rate agreements to help manage some of our interest rate risks. We report our interest rate agreements at fair value. Those with a positive value to us are reported as an asset and those with a negative value to us are reported as a liability. We may elect hedge accounting treatment under Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities (FAS 133), or we may account for these as trading instruments. See Note 5 for a further discussion on interest rate agreements.
We enter into commitments to purchase loans. These commitments are accounted for as derivatives under Statement of Financial Accounting Standards No. 149, Amendment of Statement 133 on Derivative Instruments and Hedging Activities (FAS 149), when applicable. These are classified as trading instruments on our Consolidated Balance Sheets until the date of settlement and changes in fair value of the commitments are recorded through Net Recognized Gains and Valuation Adjustments in the Consolidated Statements of Income.
Redwood Debt
Redwood debt is short-term debt collateralized by loans and securities. We report this debt at its unpaid principal balance. We may use Redwood debt to fund assets temporarily as we accumulate them for future sale to securitization entities. Increasingly, we will use Redwood debt to fund loans and securities that do not have significant credit risk and that we believe can generate an attractive return on the capital employed.
Asset-Backed Securities Issued
The majority of the liabilities reported on our Consolidated Balance Sheets represents ABS issued by bankruptcy-remote securitization entities sponsored by Redwood. These ABS issued are carried at their unpaid principal balances net of any unamortized discount or premium. Our exposure to loss from consolidated securitization entities (such as Sequoia and Acacia) is limited (except, in some circumstances, for limited loan repurchase obligations) to our net investment in securities we have acquired from these entities. As required by the governing documents related to each series of ABS, Sequoia and Acacia assets are held in the custody of trustees. Trustees collect principal and interest payments (less servicing and related fees) from the assets and make corresponding principal and interest payments to the issued ABS. ABS obligations are payable solely from the assets of these entities and are non-recourse to Redwood.
Other Liabilities
Accrued Interest Payable
Accrued interest payable represents interest due and payable on Redwood debt and ABS issued. It is generally paid within the next month with the exception of interest due on Acacia ABS which is generally settled quarterly.
Accrued Expenses and Other Liabilities
Accrued expenses and other liabilities on our Consolidated Balance Sheets include cash held back from borrowers, derivatives margin liability, accrued employee bonuses, executive deferred compensation, dividend equivalent rights (DERs) payable, excise and income taxes, and accrued legal, accounting, consulting, and other miscellaneous expenses.

Dividends Payable
Dividends payable reflect any dividend declared by us but not yet distributed to our stockholders as of the financial statement date.
Income Taxes
We have elected to be taxed as a REIT under the Internal Revenue Code and the corresponding provisions of state law. In order to qualify as a REIT, we must distribute at least 90% of our annual REIT taxable income (this does not include taxable income retained in our taxable subsidiaries) to stockholders within the time frame set forth in the tax rules and we must meet certain other requirements. If these requirements are met, we generally will not be subject to Federal or state income taxation at the corporate level with respect to the REIT taxable income we distribute to our stockholders. We may retain up to 10% of our REIT taxable income and pay corporate income taxes on this retained income while continuing to maintain our REIT status.
We have recorded a provision for income taxes in our Consolidated Statements of Income based upon our estimated liability for Federal and state income tax purposes. These tax liabilities arise from estimated taxable earnings in taxable subsidiaries and from the planned retention of a portion of our estimated REIT taxable income. See Note 8 for a further discussion on income taxes.
Net Income per Share
Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common shares and potential common shares outstanding during the period. Potential common shares outstanding are calculated using the treasury stock method, which assumes that all dilutive common stock equivalents are exercised and the funds generated by the exercises are used to buy back outstanding common stock at the average market price of the common stock during the reporting period.

Pursuant to EITF 03-6, Participating Securities and the Two — Class Method under FASB No. 128 (EITF 03-6), we determined that there was no allocation of income for our outstanding stock options as they were antidilutive during the three and nine months ended September 30, 2006 and 2005. There were no other participating securities, as defined by EITF 03-6, during the three and nine months ended September 30, 2006 and 2005. For the three and nine months ended September 30, 2006, the number of outstanding stock options that were antidilutive totaled 369,343 and 384,399, respectively. For the three and nine months ended September 30, 2005, the number of outstanding stock options that were antidilutive totaled 368,522 and 167,622, respectively.
Other Comprehensive Income
Current period net unrealized gains and losses on real estate loan CES, real estate securities available-for-sale, and interest rate agreements classified as cash flow hedges are reported as components of other comprehensive income on our Consolidated Statements of Comprehensive Income. Net unrealized gains and losses on securities and interest rate agreements held by our taxable REIT subsidiaries that are reported in other comprehensive income are adjusted for the effects of tax, thus creating deferred tax assets (liabilities).
Stock-Based Compensation
As of September 30, 2006 and December 31, 2005, we had one stock-based employee compensation plan and one employee stock purchase plan. These plans, and associated stock options and other equity awards, are described more fully in Note 10.
We adopted Statement of Financial Accounting Standards No. 123R, Share-Based Payment (FAS 123R), on January 1, 2006. With the adoption of FAS 123R, the grant date fair value of all remaining unvested stock compensation awards (stock options, deferred stock units, and restricted stock) are expensed on the Consolidated Statements of Income over the remaining vesting period. At January 1, 2006, upon adoption of FAS 123R, we had $19.3 million of unamortized costs related to non-

14

NOTES TO FINANCIAL STATEMENTS — (Continued)
vested equity awards (stock options, restricted stock, and deferred stock units). At September 30, 2006, the unamortized costs totaled $11.4 million and will be expensed over the next four years, over half of which will be recognized over the next twelve months.
Beginning in 2003, in accordance with the guidance of Statement of Financial Accounting Standards No. 148, Accounting for Stock Based Compensation — Transition and Disclosure, an amendment for FASB Statement No. 123 (FAS 148), we elected to prospectively apply the fair value method of accounting for stock-based awards issued after December 31, 2002. We accounted for all stock-based compensation awards issued prior to December 31, 2002 under the recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees (APB 25), and related interpretations. Under APB 25, when we granted option awards we did not include any stock-based employee compensation cost in net income, as all option awards granted had an exercise price equal to the fair market value of the underlying common stock on the date of grant. All other equity awards (deferred stock units and restricted stock), were valued at the grant date and expensed over the vesting period (regardless of when they were granted). Had we also applied Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (FAS 123), to option awards granted prior to 2003, net income and net income per share would have been the pro-forma amounts indicated in the table below for the three and nine months ended September 30, 2005. Since we adopted FAS 123R as of January 1, 2006, there is no pro-forma presentation for the three and nine months ended September 30, 2006.

The Black-Scholes option-pricing model was used in determining fair values of option grants accounted for under FAS 123R and FAS 123. The model requires the use of assumptions such as strike price, expected life, risk free rate of return, and stock price volatility. Options are generally granted over the course of the calendar year. Certain options have dividend equivalent rights (DERs) and, accordingly, the assumed dividend yield was zero for these options. Other options granted have no DERs and the assumed dividend yield was 10%. There were no options granted during the three months ended September 30, 2006 and 2005. The following table describes the weighted average of assumptions used for calculating the value of options granted during the nine months ended September 30, 2006 and

Recent Accounting Pronouncements
In February 2006, the FASB issued Statement 155, Accounting for Certain Hybrid Financial Instruments, (FAS 155), to amend FAS 133 and FAS 140. This Statement simplifies the accounting for certain financial instruments by allowing an entity to make an irrevocable election on a specific instrument basis for certain financial assets and liabilities that contain embedded derivatives that would otherwise require bifurcation and to recognize and re-measure at fair value these instruments so elected. Thus, under this election, an entity would measure the entire hybrid financial instrument at fair value with changes in fair value recognized in earnings. FAS 155 will become effective for us as of January 1, 2007. We are currently assessing the impact on our financial statements.
In March 2006, the FASB issued Statement 156, Accounting for Servicing of Financial Assets — an amendment of FASB Statement No. 140 (FAS 156). This Statement amends FAS 140 with respect to the accounting for separately recognized servicing assets and servicing liabilities. FAS 156 requires an entity to either (i) recognize servicing assets or servicing liabilities initially at fair value and amortize this value over the period of servicing, or (ii) measure servicing assets or liabilities at fair value at each reporting date with changes in fair value reported in earnings. FAS 156 will become effective for us as of January 1, 2007. We believe FAS 156 will not have a material impact on our financial statements.
In July 2006, the FASB released Accounting for Uncertainty In Income Taxes (FIN 48). FIN 48 addresses the recognition and measurement of uncertain income tax positions using a “more-likely-than-not” threshold and introduces a number of new disclosure requirements. The differences between current practice and the requirements of FIN 48 are significant, and a substantial effort will be required by most companies to properly assess all material uncertain positions. Further, the impact of FIN 48 is not just technical; the interpretation may cause companies to modify their tax-related strategies. The new guidance will become effective for us January 1, 2007. We are currently assessing the impact on our financial statements.
In September 2006, the FASB issued Statement 157, Fair Value Measurements, (FAS 157). This statement clarifies the definition of fair value, the methods used to measure fair value, and requires expanded financial statement disclosures about fair value measurements for assets and liabilities. FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. The new guidance will be effective for us January 1, 2008 and we are currently assessing the impact on our financial statements.
In September 2006, the SEC’s Office of the Chief Accountant and Divisions of Corporation Finance and Investment Management released Staff Accounting Bulletin No. 108 (SAB 108), which provides interpretive guidance on how registrants should quantify financial-statement misstatements. Currently, the two methods most commonly used by preparers and auditors to quantify misstatements are the “rollover” method (which focuses primarily on the income statement impact of misstatements) and the “iron curtain” method (which focuses primarily on the balance sheet impact of misstatements). Under SAB 108, registrants will be required to consider both the rollover and iron curtain methods (i.e., a dual

16


Table of Contents

REDWOOD TRUST, INC. AND SUBSIDIARIES
NOTES TO FINANCIAL STATEMENTS — (Continued)
approach) when evaluating the materiality of financial statement errors. Registrants will need to revisit their prior materiality assessments and consider them using both the rollover and iron curtain methods.
SAB 108 is effective for annual financial statements in the first fiscal year ending after November 15, 2006, therefore for us, the year ended December 31, 2006. The SAB provides transition accounting and disclosure guidance for situations in which a registrant concludes that a material error(s) existed in prior-period financial statements under the dual approach. Specifically, registrants will be permitted to restate prior period financial statements or recognize the cumulative effect of initially applying SAB 108 through an adjustment to beginning retained earnings in the year of adoption. We believe SAB 108 will not have a material impact on our annual financial statements.
In the first quarter of 2006, we became aware of a potential technical interpretation of GAAP that differs from our current accounting presentations. This issue relates to the accounting for transactions where assets are purchased from a counterparty and simultaneously financed through a repurchase agreement with that same counterparty and whether these transactions create derivatives instead of the acquisition of assets with related financing (which is how we currently present these transactions). This potential technical interpretation of GAAP does not affect the economics of the transactions but may affect how the transactions would be reported in our financial statements. Our cash flows, our liquidity, and our ability to pay a dividend would be unchanged, and we do not believe our taxable income would be affected. We have not changed our accounting treatment for this potential issue. However, if we were to change our current accounting presentations based on this interpretation, we do not believe there would be a material impact on our consolidated financial statements.
NOTE 3.  EARNING ASSETS
As of September 30, 2006 and December 31, 2005 our reported earning assets (owned by us or by consolidated securitization entities) consisted of investments in adjustable-rate, hybrid, and fixed-rate real estate loans and securities. Adjustable-rate loans have coupons that reset at least annually. Hybrid loans have an initial fixed coupon rate for three to ten years followed by periodic (usually annual or semi-annual) adjustments. The original maturity of the majority of our residential real estate loans and residential real estate securities is usually twenty-five to thirty years. The original maturity of our HELOCs is generally ten years. The original maturity of our commercial real estate loans and commercial real estate securities is generally ten years. The actual maturity is subject to change based on the prepayments of the underlying loans.
For the three months ended September 30, 2006 and 2005, the average consolidated balance of earning assets was $12.9 billion and $20.1 billion, respectively. For the nine months ended September 30, 2006 and 2005, the average consolidated balance of earning assets was $13.9 billion and $22.2 billion, respectively.
Real Estate Loans
We acquire real estate loans from third party originators for sale to securitization entities sponsored by us under our Sequoia program which, in turn, issue ABS (that are shown as liabilities on our Consolidated Balance Sheets). The following tables summarize the carrying value of real estate loans, which

Of the $9.8 billion of face and $141 million of unamortized premium on our real estate loans at September 30, 2006, $6.0 billion of face and $114 million of unamortized premium relates to loans acquired prior to July 1, 2004. The loans acquired prior to July 1, 2004 had face and unamortized premium balances of $9.7 billion and $138 million, respectively, at December 31, 2005. During the first nine months of 2006, 39% of these loans prepaid and we amortized 17% of the premium over the first nine months of 2006. For these loans acquired prior to July 2004, we use coupon interest rates as they change over time and anticipated principal payments to determine an effective yield to amortize the premium or discount. For real estate loans acquired after July 1, 2004, the face and unamortized premium was $3.8 billion and $27 million at September 30, 2006 and $4.1 billion and $38 million at December 31, 2005, respectively. For these loans acquired after July 1, 2004, we use the initial coupon interest rate of the loans (without regard to future changes in the underlying indices) and anticipated principal payments to calculate an effective yield to amortize the premium or discount.

Some of the real estate loans we acquire from third party originators, we sell to securitization entities that finance their purchases of loans from us through the issuance of ABS. During the period that we accumulate loans for securitization, we fund these loans with equity and with short-term debt sourced through various whole loan-financing facilities available to us. Our Consolidated Statements of Cash Flows record the proceeds from any principal payments or sales in the same category as our original acquisition was recorded. The table below presents information regarding real estate loans pledged under our borrowing agreements and owned by securitization entities.

At September 30, 2006, our residential CES provided credit-enhancement on $225 billion of residential real estate loans, and our commercial first-loss CES provided credit-enhancement on $36 billion of commercial real estate loans. At December 31, 2005, our residential CES provided credit-enhancement on $170 billion of residential real estate loans, and our commercial first-loss CES provided credit-enhancement on $26 billion of commercial real estate loans.
The amount of designated credit protection equals the amount of credit losses within the underlying loan pool that we expect to incur over the life of the loans. This estimate is determined based upon various factors affecting these assets, including economic conditions, characteristics of the underlying loans, delinquency status, past performance of similar loans, and external credit protection. We use a variety of internal and external credit risk cash flow modeling and portfolio analytical tools to assist in our assessments. Quarterly, we complete our assessments on each individual underlying loan pool and determine the appropriate level of credit protection required for each security we own. The designated credit protection is specific to each security. The following table presents the changes in our unamortized discount and the portion of the discount designated as credit protection for the three and nine months ended September 30, 2006 and 2005.

The net unamortized discount balance at September 30, 2006 of $111 million consists of $147 million of net unamortized discount on the residential CES and an effective premium of $36 million on the commercial first-loss CES. Yields recognized for GAAP for each security vary as a function of credit results, prepayment rates, and, for our securities with variable rate coupons, interest rates. If estimated future credit losses are less than our prior estimate, credit losses occur later than expected, or prepayment rates are faster than expected (meaning the present value of projected cash flows is greater then previously expected), the yield over the remaining life of the security may be adjusted upwards over time. If estimated future credit losses exceed our prior expectations, credit losses occur more quickly than expected, or prepayments occur more slowly than expected (meaning the present value of projected cash flows is less than previously expected), the yield over the remaining life of the security may be adjusted downward or we may have an other-than-temporary impairment. For the three and nine months ended September 30, 2006, we recognized other-than-temporary impairments of $0.5 million and $6.0 million, respectively. For the three and nine months ended September 30, 2005, we recognized other-than-temporary impairments of $1.2 million and $3.3 million, respectively. These impairments are included in net recognized gains and valuation adjustments in our Consolidated Statements of Income.
Gross unrealized gains and losses represent the difference between the net amortized cost and the fair value of individual securities. Gross unrealized losses represent a decline in market value for securities not deemed impaired for GAAP. The following table shows the gross unrealized losses, fair value, and length of time that any real estate securities have been in a continuous unrealized loss position as of September 30, 2006. These unrealized losses are not considered to be other-than-temporary impairments because these losses are not due to adverse changes in cash flows and we have the intent and ability to hold these securities for a period sufficient for these securities to potentially recover their values.

We generally fund the first-loss and second-loss interests of residential securities and first-loss commercial securities with equity capital. We sell the other interests we acquire to securitization entities (generally, Acacia) that re-securitize these assets by issuing ABS. Prior to sale to these securitization entities, we may fund some of the securities acquired on a temporary basis with short-term borrowings through various financing facilities available to us. The table below presents information regarding our securities pledged under borrowing agreements and owned by securitization entities as of September 30, 2006 and December 31, 2005.

During the course of preparing the financial statements for the period ended June 30, 2006, we discovered two errors and under the provisions of Statement of Financial Accounting Standards No. 154, Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3 (FAS 154), we analyzed the errors for each period affected. The accrual rate for interest income on certain securities and interest expense on certain ABS issued had been incorrectly applied and not correctly adjusted. The impact of this error was that on a cumulative basis we had overstated interest income by $1.3 million and understated interest expense by $0.2 million. Additionally, due diligence expenses for certain securities purchased had been incorrectly capitalized and amortized. The impact of this error was that on a cumulative basis we had understated operating expenses by $0.6 million and overstated mortgages securities on the Consolidated Balance Sheets.
After carefully assessing the effect of these errors on previously reported earnings and the effect of recording a total cumulative correcting adjustment of $2.1 million in the second quarter of 2006, we determined that the errors were not material to the financial statements for the six months ended June 30, 2006 and the year ended December 31, 2006. Accordingly, cumulative correcting adjustments for these errors were recorded in the second quarter of 2006.
NOTE 4.  RESERVES FOR CREDIT LOSSES
We establish and maintain credit reserves that we believe represent probable credit losses in our consolidated real estate loans held-for-investment as of the date of the financial statements. The reserves for credit losses are reflected as a component of real estate loans on our Consolidated Balance Sheets.
Our loan servicers advance payment on delinquent loans to the extent they deem them recoverable. We generally accrue interest on delinquent loans to the extent cash is received; any potential loss is included in our credit reserve. When a loan becomes REO, we estimate the specific loss, based on estimated net proceeds from the sale of the property (including accrued but unpaid interest), and charge this specific estimated loss against the reserve for credit losses. A majority of the residential loans consolidated on our balance sheet have interest-only payments for an initial term. Any increased credit risk that these loans may contain is reflected in our analysis and determination of the appropriate credit reserves.

Delinquencies in our consolidated residential real estate loans were $61 million and $37 million as of September 30, 2006 and December 31, 2005, respectively. Delinquencies include loans delinquent more than 90 days, in bankruptcy, in foreclosure, and REO. As a percentage of our residential real estate loans, delinquencies stood at 0.63% and 0.27% of our current loan balances as of September 30, 2006 and December 31, 2005, respectively. We had no delinquent commercial real estate loans as of September 30, 2006 and December 31, 2005.
Reserve for Deferred Interest
For first and second loss securities owned, backed by negatively amortizing loans, we intend to recognize interest income when we receive the cash — either currently, or at a later date, according to the terms of the loan.
To the extent we own any first- or second-loss securities with underlying loans that do not make the fully indexed payment, we do not recognize any unpaid interest as income. That is, we only recognize the actual interest paid by establishing a reserve for the amounts the loans negatively amortize. These reserves are netted against our accrued interest receivable. During the three and nine months ended September 30, 2006, we increased our reserve for deferred interest by $1.1 million and $2.9 million, respectively, against interest income on these securities. During both the three and nine months ended September 30, 2005, we increased our reserve for deferred interest by $0.3 million. At September 30, 2006, the outstanding reserve for deferred interest was $3.7 million.
One commercial loan that we own, in accordance with the contractual arrangements, began deferring interest payments in 2006, though we may receive these amounts at a later date. Consistent with our accounting practice on negatively amortizing loans, we did not recognize the $0.1 million and $0.5 million of interest accrued and not paid on this loan, during the three and nine months ended September 30, 2006, respectively.
NOTE 5.  INTEREST RATE AGREEMENTS AND PURCHASE COMMITMENTS
We maintain an overall interest rate risk management strategy that incorporates the use of derivative interest rate agreements for a variety of reasons, including reducing significant fluctuations in earnings or market values on certain assets or liabilities that may be caused by interest rate volatility. Currently, the majority of our interest rate agreements are used to match the duration of liabilities to assets. Interest rate agreements we use as part of our interest rate risk management strategy may include interest rate options, swaps, options on swaps, futures contracts, options on futures contracts, and options on forward purchase commitments.
We may designate the interest rate agreement as (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge), (2) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability

27

NOTES TO FINANCIAL STATEMENTS — (Continued)
(cash flow hedge), or (3) held for trading (trading instrument). We currently have elected cash flow hedging treatment for certain interest rate agreements and treat other interest rate agreements as trading instruments.
We discontinue hedge accounting when (1) we determine that the derivative is no longer expected to be effective in offsetting changes in the fair value or cash flows of the designated hedged item; (2) the derivative expires or is sold, terminated, or exercised; (3) the derivative is de-designated as a fair value or cash flow hedge; or (4) it is probable that the forecasted transaction will not occur by the end of the originally specified time period.
We incur credit risk to the extent that the counterparties to the interest rate agreements do not perform their obligations under the interest rate agreements. If one of the counterparties does not perform, we may not receive the cash to which we would otherwise be entitled under the interest rate agreement. In order to mitigate this risk, we only enter into interest rate agreements that are either (a) transacted on a national exchange or (b) transacted with counterparties that are either (i) designated by the U.S. Department of Treasury as a primary government dealer, (ii) affiliates of primary government dealers, or (iii) rated AA or higher. Furthermore, we generally enter into interest rate agreements with several different counterparties in order to diversify our credit risk exposure and maintain margin accounts with them.
We report our interest rate agreements at fair value as determined using third-party models and confirmed by Wall Street dealers. As of September 30, 2006 and December 31, 2005, the net fair value of interest rate agreements was $23.6 million and $30.7 million, respectively, and are summarized in the table below. See Note 10 for the impact of these fair value changes on Accumulated Other Comprehensive Income.

We have elected cash flow hedging treatment for many of our existing interest rate agreements. For these interest rate agreements, the ineffective portion of the hedging derivative is recognized immediately in earnings. We anticipate having some ineffectiveness in our hedging program, as not all terms of our hedges and not all terms of our hedged items match perfectly. We use the dollar-offset method to determine the amount of ineffectiveness. For the three and nine months ended September 30, 2006, the amount of ineffectiveness was $0.3 million and $0.5 million of income, respectively. For both the three and nine months ended September 30, 2005, the amount of ineffectiveness was $0.1 million of expense.

During the course of preparing the financial statements for the period ended September 30, 2006 we discovered an error in the valuation of certain interest rate agreements for the purpose of measuring the amount of hedge ineffectiveness under FAS 133. Under the provisions of Statement of Financial Accounting Standards No. 154, Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3 (FAS 154), we analyzed the errors for each period affected. The impact of this error was that on a cumulative basis we had understated interest expense (negative ineffectiveness) by $1.0 million and overstated other comprehensive income by $1.0 million.
After carefully assessing the effect of this error on previously reported earnings and the effect of recording a total cumulative correcting adjustment in the third quarter of 2006, we determined that the errors were not material to the financial statements for the nine-months ended September 30, 2006 and the year ended December 31, 2006. Accordingly, a cumulative correcting adjustment for this error was recorded in the third quarter of 2006.
Should we choose to terminate a cash flow hedge, the value of that hedge is reclassified from accumulated other comprehensive income into earnings over time. The timing of the reclassification depends on the status of the hedged or forecasted transaction. If the hedged transaction no longer exists, or the forecasted transaction is no longer expected to occur, then the reclassification occurs immediately. If the hedged transaction still exists, or the forecasted transaction is still expected to occur, then the reclassification occurs over the original period of such transaction. We have terminated cash flow hedges where the hedged transaction still existed or is still expected to occur. For the three and nine months ended September 30, 2006, the amount reclassified from other comprehensive income to interest expense totaled negative $0.1 million and positive $0.4 million, respectively. For the three and nine months ended September 30, 2005, the amount reclassified from other comprehensive income to interest expense totaled negative $0.1 million and negative $0.3 million, respectively.
Also included in our interest expense in our Consolidated Statements of Income is the net cash receipts (payments) on interest rate agreements designated as cash flow hedges. For the three and nine months ended September 30, 2006, the net cash receipts credited to interest expense totaled $3.0 million and $9.1 million, respectively. For the three and nine months ended September 30, 2005, the net cash receipts credited to interest expense totaled $0.8 million and $3.4 million, respectively.
We do not elect hedge accounting treatment for some of our interest rate agreements and these are accounted for as “trading” instruments. Thus, changes in the market value of these interest rate agreements and associated income and expenses are reported through our earnings and appear in net recognized gains (losses) and valuation adjustments in our Consolidated Statements of Income.
We also enter into commitments to purchase loans. These commitments are accounted for as derivatives under Statement of Financial Accounting Standards No. 149, Amendment of Statement 133 on Derivative Instruments and Hedging Activities (FAS 149), where applicable and are accounted for as trading instruments. During the three months ended September 30, 2006 we entered into commitments to purchase $93 million of residential hybrid loans that will settle in the fourth quarter of 2006.
For the three months ended September 30, 2006, the amount of market value changes associated with interest rate agreements accounted for as trading instruments totaled negative $8.5 million and the fair value change on loan purchase commitments was positive $3.7 million. For the nine months ended September 30, 2006, the amount of market value changes associated with interest rate agreements accounted for as trading instruments was positive $1.0 million and the fair value change related to loan purchase commitments was positive $0.1 million. For the three and nine months ended September 30, 2005, the amount of market value changes associated with interest rate agreements accounted for as trading instruments totaled positive $0.1 million and negative $0.6 million, respectively.

In 2005, we formed Madrona Residential Funding, LLC (“Madrona”), a special purpose entity and wholly owned subsidiary of Holdings. Madrona gives us the flexibility to access the capital markets and issue short-term debt instruments to finance the accumulation of loans prior to sale to sponsored securitization entities. Madrona is designed to fund residential loans accumulated for eventual sale to our Sequoia securitization program by issuing A1+/P1 rated commercial paper. Madrona was established to accumulate up to $1.5 billion of loans (although the current authorization is for $490 million) and can warehouse each loan up to 270 days. There are specific eligibility requirements for financing loans in this facility that are similar to our existing financing facilities with several banks and large investment banking firms. There is a credit reserve account for approximately 70 basis points that will serve as credit-enhancement to the commercial paper investors. In addition, we issued $5.4 million of a BBB-rated Madrona ABS to provide further credit support. This facility has a three-year term. As of September 30, 2006 there was no commercial paper outstanding.
We have facilities available with several banks and major investment banking firms for financing real estate loans and securities and an unsecured line of credit with a bank. Additional collateral in the form of additional qualifying assets or cash may be required to meet changes in market values from time to time under these agreements. Many of these facilities for securities have no expiration date. The table below summarizes our available facilities as of September 30, 2006 and December 31, 2005 by collateral type.

Borrowings under these facilities generally bear interest based on a specified margin over the one-month London Inter-Bank Offered Rate (LIBOR). interest rate. We continue to be in compliance with all of our debt covenants for all of our borrowing arrangements and credit facilities. Covenants associated with our debt generally relate to our tangible net worth, liquidity reserves, and leverage requirements. We have not had, nor do we currently anticipate having, any problems in meeting these covenants. It is our intent to renew facilities and pursue additional facilities and other types of financing as needed.
NOTE 7.  ASSET-BACKED SECURITIES ISSUED
Securitization entities sponsored by us issue ABS to raise the funds to acquire assets from us and others. Each series of ABS consists of various classes that pay interest at variable and fixed rates. Substantially all of the ABS is indexed to one-, three-, or six-month LIBOR. A lesser amount of the ABS are fixed for a term and then adjust to a LIBOR rate (hybrid ABS) or are fixed for their entire term. Some of the ABS interest only (IOs) issued have a fixed spread, while others earn a coupon based on the spread between collateral owned and the ABS issued by the securitized entity. The maturity of each class is directly affected by the rate of principal prepayments on the assets of the issuing entity. Each series is also subject to redemption (call) according to the specific terms of the respective governing documents. As a result, the actual maturity of any class of ABS is likely to occur earlier than its stated maturity.

The ABS issued by securitization entities sponsored by us are collateralized by real estate loans and securities. The ABS collateralized by residential real estate loans (and some residential securities) are typically securitized through entities with the brand name Sequoia. Residential real estate loan collateral consists primarily of conventional, 25- or 30-year, adjustable-rate and hybrid residential real estate loans secured by first liens on one- to four-family residential properties. HELOC collateral consists of adjustable-rate first and second lien residential loans with a ten-year revolving period and a maturity from origination of ten years. The ABS issued that are collateralized by real estate securities and commercial real estate loans are typically issued through entities with the brand name Acacia. Other ABS collateralized by commercial loans are issued on an individual basis. For financial reporting purposes the assets and liabilities of these entities appear on our Consolidated Balance Sheets. The ABS issued by Madrona Residential Funding LLC (Madrona ABS) represents a form of additional credit support potentially available to the purchasers of the commercial paper.

NOTE 8.  TAXES
For tax purposes, a REIT can deduct dividends paid from REIT taxable income, and thus effectively reduce or eliminate corporate-level income taxes on REIT income. A REIT can retain up to 10% of its REIT taxable income, maintain its REIT status, and be taxable at corporate rates on retained income. As of September 30, 2006, we had met all of the dividend distribution requirements of a REIT.
Under the Internal Revenue Code, a dividend declared by a REIT in October, November, or December of a calendar year and payable to stockholders of record as of a specified date in such year will be deemed to have been paid by the REIT and received by the stockholders on the last day of that calendar year, provided the dividend is actually paid before February 1st of the following calendar year, and provided that the REIT has any remaining undistributed REIT taxable income on the record date. Therefore, the regular dividends declared in the fourth quarter of 2005 that were paid in January 2006 are considered taxable income to stockholders in 2005 (the year declared).
Our 2005 dividend distributions declared before December 31, 2005 and distributed on or before January 31, 2006, were less than 85% of our estimated 2005 REIT taxable income. This resulted in a 4% excise tax provision on the shortfall. We anticipate following a similar pattern in 2006. For the three and nine months ended September 30, 2006, we provided for excise tax of $0.3 million and $0.9 million, respectively, which is reflected as a component of operating expenses on our Consolidated Statements of Income. For the three and nine months ended September 30, 2005, we provided for excise tax of $0.3 million and $0.9 million, respectively. As of September 30, 2006 and December 31, 2005, accrued excise tax payable was $0.9 million and $1.2 million, respectively, and was reflected as a component of accrued expenses and other liabilities on our Consolidated Balance Sheets.

We currently plan to retain approximately 10% of our 2006 REIT ordinary taxable income (as we have in the previous three years) and will be subject to corporate level income taxes on any retained income for the 2006 calendar tax year. We plan to distribute any net capital gains (gains generated from calls and sales offset by losses on IOs as a result of calls) that we generate to allow our stockholders to potentially take advantage of a lower tax rate on those distributions.
The following table summarizes the tax provisions for the three and nine months ended September 30, 2006 and 2005.

  $ 3,538     $ 4,693     $ 9,563     $ 13,424  
                         
The Federal and State tax provision for corporate income tax is estimated based on the amount of REIT ordinary income that we permanently retained, or plan to retain and estimated taxable income at our taxable REIT subsidiaries. Taxable REIT subsidiaries’ deferred tax provisions are attributable to temporary differences between GAAP and tax accounting treatments on securitization gains and the utilization of prior period deferred tax assets.
As of September 30, 2006 and December 31, 2005, our taxable REIT subsidiaries had net deferred tax assets as presented in the table below. Realization of the deferred tax asset is dependent on many factors including generating sufficient taxable income prior to the expirations of net operating loss carry forwards. Although realization is not assured, we believe it is more likely than not that most of the deferred tax asset will be realized. The amount of the deferred tax asset considered realizable, however, could be reduced if revised estimates of future taxable income during the carry forward periods are lower than expectations.

NOTES TO FINANCIAL STATEMENTS — (Continued)
In accordance with FAS 109, “Accounting for Income Taxes,” deferred tax assets (liabilities) are recognized for GAAP items relating to unrealized gains (losses) recognized through other comprehensive income. Deferred tax assets (liabilities) are recognized for these items in order to take into account potential tax effects if these unrecognized gains (losses) are realized in the future through the Consolidated Statements of Income. Any deferred tax assets (liabilities) recognized for these items are booked through equity as opposed to the provision for income taxes in the Consolidated Statements of Income.
Holdings’ state NOLs were $8.7 million and $10.1 million at September 30, 2006 and December 31, 2005, respectively. These state NOLs will expire by 2012, unless utilized. At September 30, 2006 and December 31, 2005, the valuation allowance relates exclusively to Holdings’ state NOLs which may expire before being utilized.
The statutory combined Federal and state corporate tax rate is 42%. This rate is applied to the amount of estimated REIT taxable income retained and to taxable income earned at the taxable subsidiaries. Thus, as a REIT, our effective tax rate is significantly less than the statutory combined rate as we are allowed to deduct dividend distributions. In addition, there are some permanent and temporary differences (including accounting for securitizations, stock options and other equity compensation, and other employee compensation expenses) between GAAP income and taxable income that result in changes in our effective rate from the statutory rates.
NOTE 9.  FAIR VALUE OF FINANCIAL INSTRUMENTS
We estimate the fair value of our financial instruments using available market information and other appropriate valuation methodologies. These fair value estimates generally incorporate discounted future cash flows at current market discount rates for comparable investments. We validate our fair value estimates on a quarterly basis by obtaining fair value estimates from dealers who make a market in these financial instruments. We believe the estimates we use reasonably reflect the values we may be able to receive should we choose to sell them. Many factors must be considered in order to estimate market values, including, but not limited to interest rates, prepayment rates, amount and timing of credit losses, supply and demand, liquidity, and other market factors. Accordingly, our estimates are inherently subjective in nature and involve uncertainty and judgment to interpret relevant market and other data. Amounts realized in actual sales may differ from the fair values presented.
The following table presents the carrying values and estimated fair values of our financial instruments as of September 30, 2006 and December 31, 2005.

Methodologies we use to estimate fair market values for various asset types are described below.
•  Real estate loans
  •  Residential loan and HELOC fair values are determined by available market quotes and discounted cash flow analyses and are confirmed by third party/dealer pricing indications.
 
  •  Commercial loan fair values are determined by appraisals on underlying collateral and discounted cash flow analyses.
•  Real estate securities
  •  Real estate securities fair values are determined by discounted cash flow analyses and other valuation techniques using market pricing assumptions confirmed by third party dealer/pricing indications.
•  Interest rate agreements
  •  Fair values on interest rate agreements are determined by third party vendor modeling software and from valuations provided by dealers active in derivative markets.
•  Cash and cash equivalents
  •  Includes cash on hand and highly liquid investments with original maturities of three months or less. Fair values equal carrying values.
•  Restricted cash
  •  Includes interest-earning cash balances in ABS entities for the purpose of distribution to bondholders and reinvestment. Due to the short-term nature of the restrictions, fair values approximate carrying values.
•  Accrued interest receivable and payable
  •  Includes interest due and receivable on assets and due and payable on our liabilities. Due to the short-term nature of when these interest payments will be received or paid, fair values approximate carrying values.
•  Redwood debt
  •  All Redwood debt is adjustable and matures within one year; fair values approximate carrying values.
•  ABS issued
  •  Fair values are determined by discounted cash flow analyses and other valuation techniques confirmed by third party/dealer pricing indications.
•  Commitments to purchase
  •  Fair values are determined by discounted cash flow analyses and other valuation techniques confirmed by third party/dealer pricing indications.

Accumulated Other Comprehensive Income
Certain assets are marked to market through accumulated other comprehensive income on our Consolidated Balance Sheets. These adjustments affect our book value but not our net income. As of September 30, 2006 and December 31, 2005, we reported net accumulated other comprehensive income of $94.8 million and $73.7 million, respectively.

Also included in accumulated other comprehensive income at September 30, 2006, was a net gain balance of $0.1 million related to terminated cash flow hedges to be reclassified into earnings over the original period of the transaction. This net gain consisted of $4.1 million of hedges terminated at a gain and $4.0 million of hedges terminated at a loss. Of this net amount, $0.2 million will be recognized as interest expense on our Consolidated Statements of Income over the next twelve months. At September 30, 2006, the maximum length of time over which we are hedging our exposure to the variability of future cash flows for forecasted transactions is ten years, and all forecasted transactions are expected to occur within the next year.

Stock Option Plan
In March 2006, we amended the previously amended 2002 Redwood Trust, Inc. Incentive Stock Plan (Incentive Plan, or IP) for executive officers, employees, and non-employee directors. This amendment was approved by our stockholders in May 2006. The IP authorizes our Board of Directors (or a committee appointed by our Board of Directors) to grant incentive stock options as defined under Section 422 of the Code (ISOs), options not so qualified (NQSOs), deferred stock, restricted stock, performance shares, stock appreciation rights, limited stock appreciation rights (awards), and DERs to eligible recipients other than non-employee directors. ISOs and NQSOs awarded to employees have a maximum term of ten-years and generally vest ratably over a four-year period. NQSOs awarded to non-employee directors have a maximum term of ten years and generally vest immediately or ratably over a three- or four-year period. Non-employee directors are automatically provided annual awards under the IP. The IP has been designed to permit the Compensation Committee of our Board of Directors to grant and certify awards that qualify as performance-based and otherwise satisfy the requirements of Section 162(m) of the Code. In addition, this latest amendment incorporated the addition of performance units as a type of award under the Plan, which may be awarded to officers, directors, and employees of Redwood or any of its subsidiaries, and other persons expected to provide significant services to Redwood or any of its subsidiaries. Performance units are intended to be used for annual cash bonus payments granted to Executive Committee members who are named executive officers (the Chief Executive Officer and other four most highly compensated officers) in an amount not to exceed $5 million per grantee per year, so as to qualify as performance-based compensation under the Code. As of September 30, 2006 and December 31, 2005, 849,407 and 315,866 shares of common stock, respectively, were available for grant.
ISOs
Of the total shares of common stock available for grant, no more than 963,637 shares of common stock are cumulatively available for grant as ISOs. As of both September 30, 2006 and December 31, 2005, 551,697 ISOs had been granted. The exercise price for ISOs granted under the IP may not be less than the fair market value of shares of common stock at the time the ISO is granted.

DERs
Redwood has granted stock options that pay cash DERs. Cash DERs per applicable option are cash payments made that are equal to the per share dividends paid on common stock to our shareholders. As of September 30, 2006 and December 31, 2005, there were 1,366,462 and 1,491,403 unexercised options with cash DERs, respectively. With the adoption of FAS 123R on January 1, 2006, the grant date fair value of all remaining unvested stock options (which includes the value of any future DERs, if any) is expensed on the Consolidated Statements of Income over the remaining vesting period of each option. As of September 30, 2006, there was $2.0 million of unrecognized compensation cost related to nonvested stock options. These costs will be expensed over a weighted-average period of 1.0 years.
Redwood had granted stock options that accrue stock DERs, but no longer grants those awards. Stock DERs represented shares of stock that were issuable when the holders exercised the underlying stock options, the amount of which was based on prior dividends paid per share on common stock and the market value of the stock on the various dividend payable dates. In November 2005, all options with stock DERs were converted to options with cash DERs to comply with Internal Revenue Code Section 409A deferred compensation rules.
Redwood has also granted stock options with no DERs or where the DERs do not extend beyond the vesting period. As of September 30, 2006 and December 31, 2005, there were 135,288 and 57,009 of unexercised options with no right to DERs, respectively.
For the three and nine months ended September 30, 2006 expenses related to stock option compensation were $0.5 million and $1.5 million. For the three and nine months ended September 30, 2005, expenses related to stock option compensation were and $2.0 million and $6.2 million.
A summary of the stock option activity during the three and nine months ended September 30, 2006 and 2005 is presented below. Note 2 provides a discussion on the assumptions used to value stock options at grant date.

Restricted Stock
As of September 30, 2006 and December 31, 2005, 17,750 and 21,038 shares, respectively, of restricted stock were outstanding. Restrictions on this shares lapse through July 1, 2010. Restricted stock activity for the three and nine months ended September 30, 2006 and 2005 is presented in the table below. The cost of these grants is amortized over the vesting term using an accelerated method in accordance with FASB Interpretation No. 28 Accounting for Stock Appreciation Rights and Other Variable Stock Options or Award Plans (FIN 28), and FAS 123R. As of September 30, 2006, there was $0.4 million of unrecognized compensation cost related to nonvested restricted stock. This cost will be recognized over a weighted average period of 1.2 years. For the three and nine months ended September 30, 2006 and 2005, the expenses related to restricted stock were negligible.

Deferred Stock Units
The IP allows for the granting of Deferred Stock Units (DSUs) through the 2002 Redwood Trust, Inc., Executive Deferred Compensation Plan (EDCP). These are discussed below.
Executive Deferred Compensation Plan
In May 2002, our Board of Directors approved the 2002 EDCP. The EDCP allows eligible employees and directors to defer portions of current salary and certain other forms of compensation. Redwood may match some deferrals up to certain levels. Compensation deferred under the EDCP are assets of Redwood and subject to the claims of the general creditors of Redwood. For the three and nine months ended September 30, 2006, deferrals of $0.5 million and $2.4 million, respectively, were made under the EDCP. For the three and nine months ended September 30, 2005, deferrals of $0.1 million and $0.8 million, respectively, were made under the EDCP. The EDCP allows for the investment of deferrals in either an interest crediting account or DSUs. The rate of accrual in the interest crediting account is set forth in the EDCP. For deferrals prior to July 1, 2004, the accrual rate is based on a calculation of the marginal rate of return on our portfolio of earning assets. This accrual rate will continue for these deferred amounts through July 1, 2007 and then will be based on references to publicly traded mutual funds or the applicable federal rate (AFR). For deferrals after July 1, 2004, the accrual rate is based on

Employee Stock Purchase Plan
In May 2002, our stockholders approved the 2002 Redwood Trust, Inc. Employee Stock Purchase Plan (ESPP), effective July 1, 2002. The purpose of the ESPP is to give our employees an opportunity to acquire an equity interest in Redwood through the purchase of shares of common stock at a discount. The ESPP allows eligible employees to have up to 15% of their annual gross compensation (including base salary, bonus, and cash DERs, and subject to certain other limitations) withheld to purchase common stock at 85% of its market value. The maximum gross compensation that any participant can contribute to the ESPP in any calendar quarter is $6,250. Market value as defined under the ESPP is the lesser of the closing market price of the common stock as of the start of an offering period in the ESPP or the closing market price on the quarterly purchase date. The offering period starts on January 1st of each calendar year and consists of four quarterly purchase periods.
The ESPP allows a maximum of 100,000 shares of common stock to be purchased. As of September 30, 2006, 31,967 shares have been purchased. As of September 30, 2006 and December 31, 2005,

Direct Stock Purchase and Dividend Reinvestment Plan
For the three and nine months ended September 30, 2006, we issued 377,632 and 862,733 shares of common stock, respectively, through our Direct Stock Purchase and Dividend Reinvestment Plan (DSPP) for net proceeds of $18.1 million and $38.6 million, respectively. For the three and nine months ended September 30, 2005 112,694 and 582,250 shares were issued through our DSPP for total proceeds of $5.7 million and $31.3 million, respectively. For the three and nine months ended September 30, 2006 and 2005, we did not undertake any equity offerings.
Stock Repurchases
Our Board of Directors has approved the repurchase of a total of 7,455,000 shares of our common stock. A total of 6,455,000 shares were repurchased in 1998 and 1999. As of September 30, 2006 and December 31, 2005, there remained 1,000,000 shares available under the authorization for repurchase. Repurchased shares have been returned to the status of authorized but unissued shares of common stock.
NOTE 11. COMMITMENTS AND CONTINGENCIES
As of September 30, 2006, we were obligated under non-cancelable operating leases with expiration dates through 2018 for $17.2 million. The majority of the future lease payments relate to a ten-year operating lease for our executive offices, which expires in 2013, and a lease for additional office space at our executive offices beginning January 1, 2008 and expiring May 31, 2018. Prior to the beginning of the lease of the additional office space, we are subleasing this office space from another tenant through December 31, 2007. The total lease payments to be made under the lease expiring in 2013 and the sublease, including certain free-rent periods, are being recognized as office rent expense on straight-line basis over the lease term. Leasehold improvements for our executive offices are amortized into expense over the ten-year lease term. The unamortized leasehold improvement balance at September 30, 2006 was $1.8 million. We will incur additional leasehold improvements as we prepare the additional office space.

In November 2005, we entered into an agreement to purchase certain certificates in a commercial mortgage loan securitization to be issued by a securitization entity to be formed at a later date. We anticipate that this will require us to purchase up to 50% of any BB+ and lower grade certificates issued by this entity, on between $150 million to $200 million of loan collateral, pursuant to the underwriting criteria set forth in the agreement. As of September 30, 2006, there were approximately $150 million of commercial mortgage loans originated, but not yet securitized under this agreement. Additionally, we may be required to purchase at least 50% of a third party’s junior participation interest in this securitization, under certain circumstances (primarily where underlying loan collateral is required to be repurchased due to poor loan performance). As of September 30, 2006, we have not been required to purchase any junior participation interest; all loans funded to date are performing as expected. At September 30, 2006, we estimate the value of this commitment to be negligible.
NOTE 12. RECENT DEVELOPMENTS
In October 2006, we purchased or committed to purchase $62 million residential real estate loans, and $102 million real estate securities.
In October 2006, we exercised our option to call Acacia CDO 3, and commited to sell $124 million real estate securities. The estimated GAAP gains on these sales was $5 million.
In October 2006, we called Sequoia 7 and 8. The principal balance of the residential whole loans at the time of call was $235 million.

SUMMARY AND OUTLOOK
Redwood Trust, Inc., together with its subsidiaries (Redwood, we, or us), invests in and manages real estate assets. We invest in residential and commercial real estate loans and in asset-backed securities backed by real estate loans. Our primary focus is credit-enhancing residential and commercial real estate loans. We credit-enhance loans by acquiring and managing the first-loss and other credit-sensitive securities that bear the bulk of the credit risk of securitized loans.
We seek to invest in assets that have the potential to generate high long-term cash flow returns to help support our goal of distributing an attractive level of dividends per share to shareholders over time. For tax purposes, we are structured as a real estate investment trust (REIT).
Net Income
Net income for the third quarter was $32 million ($1.22 per share) — a decline from the $56 million ($2.21 per share) we earned in the third quarter of 2005 but an increase from the $31 million ($1.20 per share) we earned in the second quarter of 2006. For the first nine months of 2006, our net income was $92 million ($3.51 per share), a decline from the $157 million ($6.26 per share) we earned in the first nine months of 2005.
The largest factor in the decline in net income has been a significant drop in income from gains generated on the sale or calls of assets. For the comparable nine month periods, income from this source dropped by $38 million. In addition, for these nine month periods, net interest income dropped by $25 million, operating expenses rose by $6 million, and tax provisions declined by $4 million.

Financial Condition
Residential Real Estate Assets
Redwood invests in and manages residential real estate loans and securities backed by residential real estate loans. At September 30, 2006, Redwood’s residential loans totaled $9.8 billion and residential securities totaled $2.2 billion.
An important part of Redwood’s business is investing in residential securities that have credit ratings that are below investment grade. For securitizations of prime residential loans, these are typically the three securities (the first-loss, second-loss, and third-loss credit-enhancement securities) that bear the bulk of the credit risk of the underlying loans, and thus credit-enhance the other securities issued from the same entity. Due to the large amount of underlying loans, these credit-enhancement assets have concentrated credit risks, and both the upside and downside that could come from taking on concentrated risks. Redwood’s residential credit-enhancement securities have grown by 21% this year, and totaled $742 million at September 30, 2006.
The underlying loans are primarily high-quality loans but also include Alt-A (medium quality) loans. The underlying loans, which total $225 billion, are nationwide with a large concentration in California. They continue to perform well from a credit perspective. For the third quarter of 2006, realized residential credit losses were $2.2 million of principal value, a rate that is less than one basis point (0.01%) on an annualized basis of the current balance of loans. Delinquencies (90+ days, in foreclosure, in bankruptcy or REO) at September 30, 2006 were 0.21% of current balance and 0.14% of original balance. For loans in prime pools, delinquencies were 0.16% of current balance and 0.11% of original balance. Alt-A pools had delinquencies of 0.60% of current balance and 0.40% of original balance.
As a result of the concentrated credit risk associated with residential loan CES, we are generally able to acquire these securities at a discount to their face (principal) value. The difference between the principal value ($1.2 billion) and carrying (market) value ($742 million) of these residential loan CES at September 30, 2006 was $469 million. Of this difference, $384 million was designated as internal credit protection (reflecting our estimate of likely credit losses on the underlying loans over the life of these securities), $147 million represented a purchase discount we are accreting into income over time and $62 million represented net unrealized mark-to-market gains.
Redwood also invests in higher-rated investment-grade residential securities. Year-to-date growth for our investment in these residential securities has been 13%, with a total portfolio of $1.4 billion at September 30, 2006. These investment-grade securities are backed by prime, Alt-A, and sub-prime loans. They are not directly exposed to first-loss credit risk as they benefit from credit-enhancement provided by others. The credit performance of these assets continues to be excellent.
Redwood buys residential real estate loans from originators. These generally high-quality loans totaled $9.8 billion on September 30, 2006. Most of these loans are adjustable-rate loans using one- or six-

month London Inter-Bank Offered Rate (LIBOR) as the adjustable-rate index. Redwood’s loan balance for these loans has declined by 29% year-to-date as prepayments have exceeded new purchases. These loans have been prepaying rapidly due to the flat yield curve (short-term interest rates such as LIBOR are high relative to longer-term interest rates). Rapid prepayments of these loans have resulted in higher levels of premium amortization expense, one reason net interest income in 2006 is lower than in 2005.
Commercial Real Estate Assets
Redwood invests in commercial real estate securities and, to a lesser degree, directly in commercial real estate loans. At September 30, 2006, commercial securities totaled $513 million and commercial loans totaled $32 million.
Redwood’s total below investment-grade commercial real estate securities were $383 million at September 30, 2006. Of these, $117 million were first-loss commercial securities. These credit-enhancement securities bear concentrated credit risks with respect to $36 billion underlying loans on office, retail, multifamily, industrial, and other income-producing properties nationwide. Overall, the underlying loans continue to perform well, with some isolated credit losses due to loan specific issues.
As a result of the concentrated credit risk associated with commercial real estate CES, we are generally able to acquire these securities at a discount to their face (principal) value. The difference between the principal value ($322 million) and carrying value ($117 million) of our first-loss commercial CES at September 30, 2006 was $205 million. Of this difference, $222 million was designated as internal credit protection (reflecting our estimate of likely credit losses on the underlying loans over the life of these securities), and $17 million represented net unrealized mark-to-market gains.
Redwood’s investment in commercial real estate securities rated investment-grade has declined by 20% year-to-date to a total of $130 million on September 30, 2006. Our investment in commercial loans has declined by 46% year-to-date to a total of $32 million at quarter-end. These assets continue to perform well from a credit perspective.
CDO Assets
Collateralized debt obligations (CDOs) are a form of securitization in which a (usually) diverse portfolio of assets is acquired by a securitization entity that creates and sells securities (CDO securities) in order to fund its asset purchases. Redwood uses CDOs as a method of funding its assets (see below) but also acquires CDO securities created by others as an asset portfolio investment. At September 30, 2006, Redwood’s portfolio of CDO securities acquired from others included $181 million investment-grade CDO securities and $18 million below-investment-grade (CDO equity) securities. These CDO securities are generally backed by residential and commercial real estate assets. Redwood’s CDO securities portfolio has grown by 28% year-to-date in 2006. These assets are generally performing well from a credit perspective.
Asset-Backed Securities Issued
Redwood has securitized the bulk of the assets shown on its consolidated balance sheet. In a securitization, Redwood sells assets to a securitization entity that creates and sells asset-backed securities (ABS) in order to fund its asset purchases. The residential whole loan securitization entities Redwood uses are generally called Sequoia and the CDO securitization entities Redwood uses are generally called Acacia. These securitization entities are bankruptcy-remote from Redwood, so that Redwood’s liabilities cannot become liabilities of the securitization entity and the ABS issued by the securitization entity cannot become obligations of Redwood Trust. Nevertheless, since according to accounting definitions Redwood controls these securitization entities, Redwood shows both the assets and liabilities of these entities on its consolidated balance sheet. On Redwood’s September 30, 2006 balance sheet, $11.9 billion (89%) of the assets shown and $11.6 billion (95%) of the liabilities shown were the assets and obligations of securitization entities.
When we securitize assets, as opposed to owning them directly and funding them with Redwood debt and equity, our reported cost of funds is higher (the cost of ABS securities issued is generally higher than that of our debt) but we utilize less equity capital (the ABS that we acquire from the securitization

require less of an equity investment than using our own debt to fund the securitized assets). As a result, our return on equity may increase after securitization. In addition, liquidity risks are generally reduced or eliminated, as the Redwood debt associated with the accumulation of these assets during their accumulation is paid off following securitization.
Redwood Debt
Our recourse debt obligations are shown on our balance sheet as Redwood debt. These obligations totaled $510 million at September 30, 2006, an increase from $170 million at the beginning of the year. All of this debt is secured by a pledge of our loans and securities. We have used Redwood debt primarily to fund the acquisition of loans and securities on a temporary basis prior to their sale to a securitization entity. In a departure from our practice in the last few years, we are starting to acquire assets as a longer-term investment that we intend to fund on an ongoing basis with Redwood debt. This accounts for a portion of the increase in Redwood debt during the third quarter. The amount of debt we would be willing to use to fund assets is determined on an asset-by-asset basis by our internal policies — on average we expect to use approximately 8% equity and 92% debt to fund high-quality liquid assets in this manner.
Interest Rate Agreements
We use interest rate agreements such as interest rate swaps to reduce the potential volatility of our earnings and book value as interest rates change. At September 30, 2006, we owned interest rate agreements with a notional value of $5 billion and a net market value of $24 million.
Equity Funding
We generally use equity (no debt or securitization) to fund investments in assets that have highly concentrated credit risks, including first-loss residential and commercial credit-enhancement securities, CDO equity securities, and similar illiquid assets. We also use equity to fund our working capital and other operating requirements.
As our Acacia CDO securitization program has evolved over the last few years, we have been able to securitize lower-rated assets such as second- and third-loss residential and commercial credit-enhancement securities. This reduces our equity capital requirements and frees cash, allowing us to acquire additional assets using the same capital base.
Excess Capital
We are not currently utilizing leverage to the extent possible under our internal policies. At September 30, 2006, if we had pledged assets and borrowed to the extent possible under our internal policies, we would have had $219 million capital in excess of that needed to fund our operations and assets. We derive our excess capital figures by calculating the amount of cash we would have available for investment if we conservatively leveraged our securitization inventory and other assets. Excess capital increased by $28 million in the third quarter, in part because we sold $47 million equity-funded first- and second-loss 2005 and 2006 vintage residential credit-enhancement securities due to concerns about the housing credit cycle. In addition, we recycled capital and freed cash by, for the first time, securitizing in Acacia $32 million of second-loss residential credit-enhancement securities In addition, we are retaining (but not investing) cash for an expected special dividend likely to be paid in December.
Stockholders’ Equity
Our reported book value at September 30, 2006 was $40.02 per share, an increase from $39.13 per share at the beginning of the quarter and $37.20 per share at the beginning of the year. Our book value per share increased this year as a result of retained earnings and increases in the net market value of our assets and interest rate agreements. Book value per share is reduced by dividends, and thus will likely decline in the fourth quarter as a result of our special dividend.
We issue equity only when we believe equity growth will enhance long-term earnings and dividends per share, compared to what they would have been otherwise. Given the amount and quality of the asset

49


Table of Contents

acquisition opportunities we anticipate seeing, we currently expect to seek additional equity (and long-term debt) capital during 2007.
Outlook
The near-term outlook for earnings, dividends, and growth depends, in part, on the how fast we employ our $219 million of excess capital. While we carry excess capital, our earnings and dividends will be lower than they would be if this capital were employed in attractive earning assets.
We believe the outlook for employing this capital is good, although the exact timing is uncertain. In commercial real estate, we have increased our capabilities and expanded our relationships, and we expect to continue to acquire commercial credit-enhancement securities. We may also resume purchases of commercial loans. We expect to increase our acquisitions of investment-grade residential, commercial, and CDO securities. As the housing market corrects and we increase our capabilities to evaluate lower-quality residential loans, an increasing percentage of these investment-grade securities will likely be backed by Alt-A and sub-prime residential loans. We are increasing our residential whole loan purchases as a result of broadening the product types we are willing to buy (currently focusing on prime-quality hybrid loans) and expanding our relationships with originators. We have the call rights to the Sequoia residential whole loan transactions we have sponsored. As these transactions become callable (starting in the fourth quarter of 2006), we will likely call these transactions and acquire the underlying seasoned high-quality adjustable-rate whole loans as an investment for Redwood. For our acquisitions of investment-grade securities and residential whole loans, we will continue to use securitization as a funding method, but we also intend to fund a growing proportion of these assets on an ongoing basis with Redwood debt. This will utilize excess capital at an approximate rate of 8% of the assets held in this manner. As a result, Redwood debt outstanding will increase.
We currently expect to make a modest level of new investments in residential credit-enhancement securities over the next few quarters. Most likely, the bulk of these investments will be in second- and third-loss securities that will be re-securitized via Acacia CDO transactions. We expect that the risk/ reward relationship for first-loss prime residential credit enhancement securities will improve over the next year or two, at which time we expect to increase our acquisition rate of these assets. As the housing market corrects, housing prices will become less vulnerable. We expect that fewer speculators and investors will be active in the housing markets, and that loan origination standards may improve somewhat. Additionally, if there is broad stress in the housing capital markets, the prices for these assets may decline, making their acquisition more attractive. As a result of our increased capabilities, we have recently been active participants in the markets for first-loss Alt-A and sub-prime credit-enhancement securities and residuals. We expect to make a small amount of investments in this area, although our acquisitions may increase if the risk/reward relationship for these improves in our opinion (perhaps as a result of housing market stress).
In our view, in the absence of a deep housing recession, the outlook for our earnings and dividends over the next few years is reasonably good. (However, we continue to expect quarter-to-quarter GAAP and tax earnings volatility for a variety of reasons, including some technical accounting and tax issues more fully described below). Housing price increases over the past several years have reduced our risk of credit loss in the future for our existing residential assets, since, for most of our residential credit risk assets, the underlying loans were originated in 2003 and 2004. Commercial property values and cash flows are increasing in many areas. Our existing portfolio of assets as a whole has the ability to generate attractive earnings, cash flows, and dividends in the future, assuming real estate credit losses do not increase materially.
Over the long term, we believe it is reasonably likely that we will be able to continue to find attractive investment opportunities, as we believe that we are an efficient competitor and because our market segments are growing (the amount of real estate loans outstanding continues to increase and the percentage of these loans that are securitized, also continues to increase).
We declared regular quarterly dividends of $0.70 per share in each of the first, second, and third quarters of 2006. Total regular dividends to date totaled $56 million, of which $52 million represented the distribution of the remainder of our 2005 REIT taxable income. Consistent with our practice in previous years, we expect to permanently retain approximately 10% of the ordinary REIT taxable income we earn during 2006, to retain the after-tax profits earned in our taxable subsidiaries, and defer

50

the distribution of a portion of our 2006 income so that it will be distributed by September 2007 through regular dividends. With these actions, and in order to meet our distribution requirements, we expect to declare a special dividend in the fourth quarter of 2006. Redwood’s Board of Directors will set the size of any special dividend, based on evolving projections of fourth quarter REIT taxable income and other factors. If the Board authorizes the dividend based on past practice, it currently appears that the special dividend this year will likely exceed $2.50 per share and could be close to the $3.00 per share special dividend we paid in December 2005.
RESULTS OF OPERATIONS
THIRD QUARTER AND FIRST NINE MONTHS — 2006 AS COMPARED TO 2005

The table below details how our interest income changed by portfolio as a result of changes in consolidated asset balances (“volume”) and yield (“rate”) for the three and nine months ended September 30, 2006 as compared to the three and nine months ended September 30, 2005. The reduction in total interest income due to declining balances was partially offset by increased yields.

Volume change is the change in average portfolio balance between periods multiplied by the rate earned in the earlier period. Rate change is the change in rate between periods multiplied by the average portfolio balance in the prior period. Interest income changes that result from changes in both rate and volume were allocated to the rate change amounts shown in the table.

Interest income on real estate loans decreased in the 2006 periods from the 2005 periods primarily as a result of lower average balances of real estate loans. This decline was partially offset by increased yields. Yields increased primarily due to increases in the short-term interest rates to which most of these loans are indexed.
In 2005 and prior years, our residential conduit acquired significant amounts of high-quality one- and six-month LIBOR adjustable-rate residential loans from originators, selling the loans to Sequoia securitization entities, and then sponsoring Sequoia securitizations of these loans. In today’s flat to inverted yield curve environment, however, ARMs indexed to LIBOR are not an attractive option for homeowners, causing origination volume of this product to decrease dramatically. Additionally, new forms of

52


Table of Contents

adjustable-rate mortgages (negative amortization, “option ARMs”, and Moving Treasury Average (MTA) ARMs) represent an increased share of the ARM market.
The flatter yield curve has also lead to faster prepayment rates on existing ARM loans. Borrowers are more inclined to refinance out of ARMs and into hybrid or fixed rate loans when the effective interest rates on ARMs are not significantly lower than the alternatives. Prepayment rates for residential ARM loans owned by Sequoia entities increased from an average CPR of 39% in the third quarter of 2005 to an average CPR of 45% in the third quarter of 2006.
Loan premium amortization expenses for residential loans acquired prior to July 2004 are influenced by prepayment rates but also are driven in a significant manner directly by trends in short-term interest rates. As short-term rates increase, premium amortization slows; as short-term rates decrease, premium amortization expenses could accelerate in a material way. For the (smaller amount of) loans acquired after July 2004, interest rate trends are less of a factor except as they may influence prepayment rates. Comparing the two third-quarter periods, premium amortization decreased by $3.3 million. Comparing the two nine-month periods, premium amortization expenses increased by $3.2 million. See Critical Accounting Policies later in this document for further explanation of loan premium amortization.
Although the overall real estate loan balance declined during the quarter, the provision for credit losses increased due to a rise in delinquencies as a percentage of the current loan balance from 0.46% as of June 30, 2006 to 0.63% as of September 30, 2006. This increase in delinquencies is in line with expectations as our loan portfolio seasons and the current balance decreases.

Interest income recognized from our real estate securities increased in the third quarter and first nine months of 2006 as compared to the third quarter and first nine months of 2005 due to growth in our portfolio over the past year and increased yields. Portfolio growth reflected our ability to find new assets at a pace in excess of our sales, calls, and principal prepayments. Yields increased for a variety of reasons, including continued rising short-term interest rates, strong credit performance and fast prepayments.
During the course of preparing the financial statements for the period ended June 30, 2006, we discovered two errors and under the provisions of Statement of Financial Accounting Standards No. 154, Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3 (FAS 154), we analyzed the errors for each period affected. The accrual rate for interest income on certain securities and interest expense on certain ABS issued had been incorrectly applied and not correctly adjusted. The impact of this error was that on a cumulative basis we had overstated interest income by $1.3 million and understated interest expense by $0.2 million. Additionally, due diligence expenses for certain securities purchased had been incorrectly capitalized and amortized. The impact of this error was that on a cumulative basis we had understated operating expenses by $0.6 million and overstated mortgages securities on the Consolidated Balance Sheets.

After assessing the effect of these errors on previously reported earnings and the effect of recording a total cumulative correcting adjustment of $2.1 million in the second quarter of 2006, we determined that the errors were not material to the financial statements for the six months ended June 30, 2006 and the year ended December 31, 2006. Accordingly, cumulative correcting adjustments for these errors were recorded in the second quarter of 2006.

Interest income recognized from residential CES increased due to growth in our portfolio over the past year and increased yields. Portfolio growth reflected our ability to find new assets at a pace in excess of our sales, calls, and principal prepayments. Yields increased as the securities within our portfolio are beginning to season and benefit from continued strong credit performance and fast prepayment rates.

Yields increased primarily as the coupon rates on adjustable-rate loan securities (which comprise over half of the portfolio) adjusted upward with the increase in short-term interest rates.
Interest Expense
Interest expense consists of interest payments on Redwood debt and consolidated ABS issued from sponsored securitization entities, plus amortization of deferred ABS issuance costs and expenses related to certain interest rate agreements less the amortization of ABS issuance premiums. ABS issuance premiums are created when interest-only (IO) securities and other ABS are issued at prices greater than principal value.

Total consolidated interest expense decreased in the 2006 periods from the 2005 periods as a result of a significant decline in consolidated ABS issued as a result of rapid prepayments of securitized loans. Offsetting a portion of the decline in balances was the higher cost of funds due to an increase in short-term interest rates as most of our debt and consolidated ABS issued is indexed to one-, three-, or six-month LIBOR. These factors are illustrated in the table below.

During the course of preparing the financial statements for the period ended September 30, 2006 we discovered an error in the valuation of certain interest rate agreements for the purpose of measuring the amount of hedge ineffectiveness under FAS 133. Under the provisions of Statement of Financial Accounting Standards No. 154, Accounting Changes and Error Corrections, a replacement of APB
Opinion No. 20 and FASB Statement No. 3 (FAS 154), we analyzed the errors for each period affected. The impact of this error was that on a cumulative basis we had understated interest expense (negative ineffectiveness) by $1.0 million and overstated other comprehensive income by $1.0 million.
After carefully assessing the effect of this error on previously reported earnings and the effect of recording a total cumulative correcting adjustment in the third quarter of 2006, we determined that the errors were not material to the financial statements for the nine-months ended September 30, 2006 and the year ended December 31, 2006. Accordingly, a cumulative correcting adjustment for this error was recorded in the third quarter of 2006.

Generally, operating expenses increased as we added personnel, systems and additional internal controls to lay the foundation for future growth. We have expanded our product lines and made significant investments in further developing our business processes and information technologies. Our efforts to build for future growth are ongoing and we expect that our operating expenses will continue to increase.
Fixed compensation expense includes employee salaries and related employee benefits. Fixed compensation expense has increased in 2006 as compared to 2005 due to increased staffing levels. Our headcount increased from 76 at September 30, 2005 to 89 at September 30, 2006. Variable compensa-

tion expense includes employee bonuses (which are generally based on the adjusted return on equity earned by Redwood and, to a lesser degree, on individual performance) and the expense of equity awards granted to employees and directors.
Due diligence expenses are costs for services related to re-underwriting and analyzing the loans we acquire or the loans we credit-enhance through the purchase of securities. These costs fluctuate from period to period, depending on the level of asset acquisitions and other factors. Our office costs, fees, and other costs have increased as a result of increases in the scale of our operations.
Net Recognized Gains (Losses) and Valuation Adjustments
The reduction in net recognized gains and valuation adjustments for 2006 compared to 2005 is primarily due to lower gains on sales and calls of residential securities. In addition, market values of interest rate agreements have fluctuated, and we are not always able to mark-to-market all of the associated assets or liabilities. We expect increasing volatility in mark-to-market income and expenses in the future for a variety of reasons, including expected increases in residential whole loans purchase commitments, interest rate agreements not accounted for as cash flow hedges, securities accounted for as “trading”, calls of Sequoia transactions that may accelerate market value losses relative to our basis in the underlying loans, and EITF 99-20 write-downs as assets come under stress due to the housing market recession. As a result of the timing of call dates, we are not expecting to realize significant amounts of call income from our residential credit-enhancement securities during 2007.
The table below provides a detail of the net recognized gains (losses) and valuation adjustments for the three and nine months ended September 30, 2006 and 2005.

The decrease in net recognized gains and valuations adjustments in the 2006 periods as compared to the 2005 periods is primarily due to lower gains on sales and calls of residential securities. Furthermore, during 2006, a portion of the recognized gains recognized were offset by the losses in derivative instruments we had entered into to manage some of the risks associated with our purchase commitments and certain securities.
Other Comprehensive Income
Our real estate securities are accounted for as AFS and are reported on our Consolidated Balance Sheets at fair market value. Many of our derivative instruments are accounted for as cash flow hedges and are reported on our Consolidated Balance Sheets at fair market value. The differences between the value of these assets and our amortized cost bases are shown as a component of Stockholders’ Equity as Accumulated Other Comprehensive Income. Periodic changes in the value of these assets are included in Other Comprehensive Income.

58


Table of Contents

There are a number of factors that affect the fair value of our assets. For certain securities and derivative instruments, changes in interest rates can have an impact on the current value. As a result of changes in market conditions (including a decrease in longer term rates) during the third quarter of 2006, the change in the value of our assets on AFS securities reported as Other Comprehensive Income increased by $31 million and the change in value of derivative instruments reported through Other Comprehensive Income decreased by $28 million.
Taxes
Provisions for Income Taxes
As a REIT, we are able to pass through substantially all of our earnings at the REIT level to stockholders without paying federal income tax at the corporate level. We pay income tax on the REIT taxable income we retain and the income we earn at our taxable subsidiaries. We provide for income taxes for GAAP purposes based on our estimates of our taxable income, the amount of taxable income we plan to permanently retain, and the taxable income we estimate was earned at our taxable subsidiaries. A portion of our income tax provision is based on current tax provisions and another portion may include changes in our deferred taxes arising from timing differences between our GAAP and taxable income recognition.
Our income tax provision in the third quarter of 2006 was $3.5 million, a decrease from the $4.7 million income tax provision taken in the third quarter of 2005. For the first nine months of 2006, our income tax provision was $9.6 million, a decrease from the $13.4 million income tax provision taken in the first nine months of 2005. Our provision for income taxes decreased for the three and nine months ending September 30, 2006 as compared to similar periods of 2005 generally due to an overall decline in earnings we are retaining at the REIT and a decline in earnings at our taxable REIT subsidiaries.
Taxable Income and Dividends
Total taxable income is not a measure calculated in accordance with GAAP. It is the pre-tax income calculated for tax purposes. Estimated REIT taxable income is an important measure as it is the basis of our dividend distributions to shareholders. REIT taxable income is that portion of our taxable income that we earn in our parent (REIT) company and its REIT subsidiaries. It does not include taxable income earned in taxable subsidiaries.
Taxable income calculations differ from GAAP income calculations in a variety of ways. For us, the most significant differences include the timing of amortization of premium and discounts and the timing of the recognition of gains or losses on assets. The rules for both GAAP and tax accounting for loans and securities are technical and complicated, and the impact of changing interest rates, actual and projected prepayment rates, and actual and projected credit losses can have a very different impact on the amount of GAAP and tax income recognized in any one period. See further discussion under Potential Tax Earnings Volatility.

Total taxable income per share and REIT taxable income per share are measured as the estimated pretax total taxable income and REIT taxable income, respectively, earned in a calendar quarter divided by the number of shares outstanding at the end of each quarter. Total taxable income per share and REIT taxable income per share for the first nine months are the sum of the first three quarters’ total taxable income per share and REIT taxable income per share, respectively.
Based on our 2005 REIT taxable income and the first nine months of 2006 estimated REIT taxable income, we estimate we had $111 million of undistributed REIT taxable income at September 30, 2006. We plan to distribute the bulk of this income as dividends to our stockholders during the remainder of 2006 and through September 2007 as we continue to meet our REIT dividend distribution requirements.
Potential GAAP Earnings Volatility
Going forward, we expect quarter-to-quarter GAAP earnings volatility for a variety of reasons, including the timing of sales and calls of assets, changes in interest rates, prepayments, credit losses, and capital utilization. In addition, volatility may occur because of technical accounting issues described below.
Loan Premium
Our unamortized loan premium on our consolidated residential loans at September 30, 2006 was $141 million and will be expensed over the remaining life of these loans. This represents a cost basis of 101.45 on the $9.8 billion of principal of these loans. For a variety of technical accounting reasons, the premium balance for these loans has not been amortized as quickly as these loans have prepaid, so our reported earnings have been higher than they would have been if, for example, the proportion of total premium amortized equaled the proportion of total principal prepaid on loans, and our accounting cost basis per loan has been increasing over time. Amortization for a significant portion of this premium balance is driven by effective yield calculations that depend on interest rates and prepayments (see Critical Accounting Policies for further details). Loan premium amortization was $11.2 million and $35.3 million in the third quarter and first nine months of 2006, respectively. Declines in short-term interest rates could cause a significant increase in required amortization in subsequent quarters.
In addition, a premium amortization adjustment could occur if we reclassify a portion of the underlying loans from held-for-investment to held-for-sale, as the GAAP carrying value of these loans are currently in excess of their fair value and the carrying value may continue to increase. This reclassification could

60


Table of Contents

occur over time as the various underlying pools of loans become callable and we decide to sell the loans, or it could occur if there is a change in accounting principles.
Real Estate Securities
Currently, all of our real estate securities are classified as available-for-sale (AFS) and are carried on our balance sheet at their estimated fair value. Cumulative unrealized gains and losses are reported as a component of accumulated other comprehensive income in our Consolidated Statements of Stockholders’ Equity.
We could experience significant earnings volatility from our real estate securities. Adverse changes to projected cash flows related to poor credit performance or adverse changes to prepayment speeds could create an other-than-temporary impairment and cause any market value losses that have not been reported in income to be expensed through the income statement.
Earnings volatility related to real estate securities may also occur if we changed the GAAP classification for existing securities from AFS to “trading” or if we use “trading” accounting for new securities acquired. Generally, changes in the fair value of “trading” securities are required to flow through our income statement. In the fourth quarter and going forward, we anticipate that certain real estate securities we acquire (those we intend to hold as an investment funded with Redwood debt) will be classified as trading securities.
Derivative Instruments
We could experience significant earnings volatility from our derivative instruments. Currently we have two classifications for derivative instruments; “trading” and cash flow hedges. All derivative instruments, regardless of classification, are reported on the Balance Sheet at fair market value. Changes to the fair value of “trading” derivative instruments are recognized through the Income Statement. To the extent we elect to hedge “trading” securities, we might increase our usage of “trading” derivative instruments. If we elect to classify our derivative instruments as cash flow hedges, we defer the effective portion of the change in fair value of our derivative instruments for Income Statement purposes. If the hedged item and the derivative instrument are not perfectly correlated, we will recognize the difference through the Income Statement.
Potential Tax Earnings Volatility
Total taxable and REIT taxable income may vary from quarter to quarter based on the timing for tax purposes of certain transactions and events or based on the application of technical regulations. This could occur for many reasons, three of which are discussed below.
CES and Loans
We are not permitted for tax purposes to anticipate, or reserve for, credit losses. Taxable income can only be reduced by actual losses. As a consequence, we are required to accrete the entire purchase discount on CES into taxable income over their expected life and cannot take credit loss provisions on loans. For GAAP purposes, we do anticipate credit losses and only accrete a portion of the CES discount into income and we do provide for loan losses. As a result, our income recognition on CES is faster for tax as compared to GAAP, especially in the early years of owning the assets. At September 30, 2006, the cumulative difference between the GAAP and tax bases on our CES was $87 million. In addition, as of September 30, 2006, we have a credit reserve of $27 million for GAAP on our residential and commercial loans, and none for tax. As we have no credit reserves for tax and a higher CES basis, any future credit losses on our CES or loans would have a more significant impact on tax earnings as compared to GAAP.
Sequoia Interest-Only certificates (IOs)
For technical tax reasons, at fast prepayment rates we are not permitted to amortize a portion of the cost basis on IOs we have acquired from Sequoia transactions until the underlying securitization is called. For this reason, our taxable income has been higher than it would have been otherwise, and our current tax basis in these IOs is higher than it would have been otherwise. We expect to call a number of

61


Table of Contents

Sequoia securitization entities over the next two years, at which time the remaining IO basis for tax would be recognized as a capital loss for tax. Capital losses generated will not reduce our ordinary income (or our requirement to distribute ordinary income as dividends). Capital losses would offset current or future capital gains realized from sales or calls of assets, and thus would reduce distributions of capital gains. Our taxable earnings will vary from quarter to quarter based on the exact timing of these Sequoia calls.
Compensation
Compensation expense for tax will vary depending on the timing of DER payments, the exercise of stock options, the distribution of DSUs, and withdrawals of deferred compensation.
Cash Requirements, Sources of Cash, and Liquidity
We use cash to fund our operating and securitization activities, invest in earning assets, service and repay Redwood debt, fund working capital, and fund our dividend distributions.
One primary source of cash is principal and interest payments received on a monthly basis from real estate loans and securities. Other sources of cash include proceeds from sales of assets to securitizations entities, proceeds from sales of other assets, proceeds from calls, borrowings, and issuance of common stock.
At September 30, 2006, Redwood had $0.5 billion of debt. Redwood debt includes repurchase agreements, bank borrowings, collateralized short-term borrowings, and a non-secured line of credit. We may also issue secured commercial paper or unsecured debt. We currently use Redwood debt to finance the accumulation of assets for future sale to securitization entities. We also intend to use Redwood debt to finance the purchase of high-quality, relatively liquid securities and loans that we intend to hold on an ongoing basis to earn net interest income. For this reason, we expect Redwood debt to increase materially.
At September 30, 2006, we had $1.0 billion of equity capital. We expect to seek to raise additional capital in 2007.
At September 30, 2006, we consolidated as liabilities on our balance sheet $12 billion of ABS issued by securitization entities. It is unclear whether this balance will grow — we expect to acquire loans and securities and fund them through securitization but we also expect to call Sequoia and Acacia transactions at an increasing pace.
Cash flows generated and used within consolidated ABS securitization entities are not directly available to Redwood, although they are shown on our Consolidated Statement of Cash Flows. Assets consolidated from these entities are not Redwood’s assets and the ABS issued by these entities are not obligations of Redwood Trust.
We have acquired credit-enhancement securities, IOs, and CDO equity securities from these securitization entities. Our investment returns on these assets depends on their contractual rights to receive distributions of principal and interest from these securitization entities, which in turn depends on the credit performance of securitization entity’s assets and other factors. In addition, we own the call rights for many of these entities, generally allowing us (when certain time, prepayment, and/or performance targets have been met) if we choose to do so to pay off the ABS liabilities of these entities and to acquire their assets.

MARKET RISKS
We seek to manage the risks inherent in our business — including but not limited to credit risk, interest rate risk, prepayment risk, and market value risk — in a prudent manner designed to ensure Redwood’s longevity. At the same time, we endeavor, to the best of our ability, to provide our stockholders with both a steady regular dividend and an attractive long-term return. In general, we seek to assume risks that can be quantified from historical experience, to actively manage such risks, to earn sufficient compensation to justify the taking of such risks, and to maintain capital levels consistent with the risks we do take.
Credit Risk
Integral to our core business is assuming the credit risk of real estate loans.
We assume credit risk with respect to real estate loans primarily through the ownership of residential and commercial real estate loans and securities. Much of our capital base is employed in owning credit-enhancement securities that have below investment-grade credit ratings due to their concentrated credit risks with respect to underlying real estate loans. Many of the loans underlying these securities are above-average in credit quality as compared to U.S. real estate loans in general, but the balance and percentage of loans with special risk factors (higher risk commercial loans, interest-only and negative amortization residential loan types, Alt-A and sub-prime residential loan quality) has been and will continue to increase. Credit losses from any of the loans in the securitized loan pools reduce the principal value of and economic returns from these lower-rated securities. We also own a wide variety of residential and commercial unsecuritized real estate loans of various quality grades — credit risks are not as concentrated in loans as they are in credit-enhancement securities, but the risks are real nevertheless. Credit losses on real estate loans can occur for many reasons. Losses rates on real

63


Table of Contents

estate loans are cyclical, and can also vary for reasons not related to the general economy. Historical experience is not always a good guide to future loan losses.
We also own investment-grade real estate securities backed by loans of various quality grades. These securities benefit from some credit protections, but if losses to the underlying loans are high enough, they could suffer credit rating downgrades, market value declines, or principal value losses.
Interest Rate Risk
Interest rates can affect the cash flows and market values of our assets, liabilities, and interest rate agreements, and thus affect our earnings and reported book value. Our general strategy with respect to interest rates is to maintain an asset/liability posture (including hedges) on a consolidated basis that assumes some interest rate risks but not to the degree that the achievement of our long-term goals would likely be affected by changes in interest rates. We are willing to accept short-term volatility of earnings and book value while seeking to achieve more attractive long-term returns.
Prepayment Risk
We seek to maintain an asset/liability posture that benefits from investments in prepayment-sensitive assets while limiting the risk of adverse prepayment fluctuations to an amount that, in most circumstances, can be absorbed by our capital base while still allowing us to make regular dividend payments. Prepayment rates are difficult to predict or anticipate, and variations in prepayment rates can materially affect our earnings and dividends in many ways. We do not believe it is possible or desirable to control these effects in the short-term. Thus our general approach is to seek to balance overall characteristics of our balance sheet so that the net present value of cash flows generated over long periods of time does not have unattractive volatility with respect to prepayment rate changes.
Market Value Risk
Most of our consolidated real estate assets are loans accounted for as held-for-investment and reported at cost. Most of these loans have been sold to Sequoia entities and, thus, changes in the market value of the loans do not have an impact on our liquidity in the long term. However, changes in market value during the accumulation period (while these loans are funded with debt) may have a short-term effect on our liquidity.
At September 30, 2006, we reported on a consolidated basis $2.9 billion of assets that were marked-to-market through our balance sheet (i.e., available-for-sale securities) but not through our income statement. Some of these assets are credit-sensitive, and all are interest-rate sensitive. Market value fluctuations of these assets can affect the balance of our stockholders’ equity base. Market value fluctuations for our securities can affect not only our earnings and book value, but also our liquidity, especially to the extent these assets are funded with short-term debt (generally prior to securitization).
Our consolidated obligations consist primarily of ABS issued. These are reported at cost, and changes in market value in these ABS have no impact on our liquidity. However, because many of our consolidated assets are funded with these ABS issued are reported at market value, the resulting reported net equity value may not necessarily reflect the true market value of our equity investments in these securitization entities.
Inflation Risk
Virtually all of our consolidated assets and liabilities are financial in nature. As a result, changes in interest rates and other factors drive our performance far more than does inflation. Changes in interest rates do not necessarily correlate with inflation rates or changes in inflation rates.
Our financial statements are prepared in accordance with GAAP. Our activities and balance sheet are measured with reference to historical cost or fair market value without considering inflation.
CRITICAL ACCOUNTING POLICIES
The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of certain assets and liabilities at the date of the

64


Table of Contents

consolidated financial statements and the reported amounts of certain revenues and expenses during the reported period. Actual results could differ from those estimates. The critical accounting policies and the possible effect of changes in estimates on our financial results and statements are discussed below. Management discusses the ongoing development and selection of these critical accounting policies with the Audit Committee of the Board of Directors.
Revenue Recognition
When recognizing revenue on consolidated earning assets, we employ the interest method and determine an effective yield to account for purchase premiums, discounts, and other net capitalized fees and costs associated with purchasing and financing real estate loans and securities.
Loan Premium Amortization
For consolidated real estate loans, the interest method is applied as prescribed under FAS 91. For loans acquired prior to July 2004, we assume future prepayments on a pool basis and apply the current interest rate to determine the effective yield for each pool of loans. During a period of rising short-term rates, the coupon is projected to increase and results in a higher effective yield. Prior to the coupon rate resetting, (generally one to six months for these loans), the amount of amortization is lower than it will be once the coupon rate resets. Thus, for the past two years, as short-term rates increased every quarter, the amount of purchase premium we amortized was less than it would have been in a flat interest rate environment and as a result, our cost basis increased on our remaining loans. The cost basis in these loans continues to exceed the estimated fair market value.
For loans acquired after July 1, 2004, we use the initial coupon interest rate of the loans (without regard to future changes in the underlying indices) and anticipated principal payments on a pool basis to calculate an effective yield and to amortize the premium or discount. Any volatility in amortization expense is dependent only on prepayments. The cost basis of these loans is approximately equal to market value.
For our consolidated securities, the interest method to determine an effective yield is applied as prescribed under FAS 91 or EITF 99-20, using anticipated principal prepayments. The use of these methods requires us to project cash flows over the remaining life of each asset. These projections include assumptions about interest rates, prepayment rates, timing and amount of credit losses, when certain tests will be met that may allow for changes in payments made under the structure of securities, estimates regarding the likelihood and timing of calls of securities at par, and other factors. We review our cash flow projections on an ongoing basis and monitor these projections based on input and analyses received from external sources, internal models, and our own judgment and experience. We constantly review our assumptions and make adjustments to the cash flows as deemed necessary. There can be no assurance that our assumptions used to generate future cash flows, or the current period’s yield for each asset, will prove to be accurate.
Under the interest method, decreases in our projected credit loss assumptions could result in increasing yields being recognized from residential and commercial real estate securities in the current period. In addition, faster-than-anticipated prepayment rates on residential loans would also tend to increase realized yields. In contrast, increases in our credit loss assumptions and/ or slower than anticipated prepayment rates could result in lower yields being recognized and an adverse change in cash flows may represent an other-than-temporary impairment under GAAP, in which case the asset may be written down to its fair value through our Consolidated Statements of Income.
Redwood applies APB 21 and APB 12 in determining its periodic amortization for the premium on its debt, including the issuance of IO securities and deferred bond issuance cost (DBIC). We arrive at a periodic interest cost that represents a level effective rate based on projected repayment rates.
Establishing Valuations and Accounting for Changes in Valuations
Changes to the fair value of securities available-for-sale are reported through our Consolidated Balance Sheets as cumulative unrealized gains and losses classified as accumulated other comprehensive income in stockholders’ equity. The exception to this treatment is when a specific impairment is

65


Table of Contents

identified and the resulting decrease in fair value is recorded in net recognized gains (losses) and valuation adjustments on our Consolidated Statements of Income.
We estimate the fair value of assets and interest rate agreements using available market information and other appropriate valuation methodologies. We believe that the estimates we use reflect market values that we may be able to receive should we choose to sell assets. Our estimates are inherently subjective in nature and involve matters of uncertainty and judgment in interpreting relevant market and other data. Many assumptions are necessary to estimate market values, including, but not limited to, interest rates, prepayment rates, amount and timing of credit losses, supply and demand, liquidity, and other market factors. We apply these factors to each of our assets, as appropriate, in order to determine market values.
We review our fair value calculations on an ongoing basis. We monitor the critical performance factors for each of our assets. Our expectations of future performance are shaped by input and analyses received from external sources, internal models, and our own judgment and experience. We review our existing assumptions relative to our and the market’s expectations of future events and make adjustments to the assumptions that may change our market values. Changes in perceptions regarding future events can have a material impact on the value of our assets. Should such changes or other factors result in significant decreases in the market values, our net income and book value could be adversely affected.
In addition to our valuation processes, we are active acquirers, issuer of debt securities, and occasional sellers of assets. Thus, we believe that we have the ability to understand and determine changes in assumptions that are taking place in the marketplace and make appropriate changes in our assumptions for valuing assets. In addition, we use third party sources to validate our valuation estimates.
There are certain other valuation estimates we make that have an impact on current period income. One such area is the valuation of certain equity grants. Under FAS 123R, we estimate the value of options, which is based on a number of assumptions, including forfeitures. Currently, most of our equity awards are restricted stock and deferred stock units and the fair values at grant equal the market value of Redwood’s common stock at the date of grant.
Credit Reserves
For consolidated real estate loans held-for-investment, we establish and maintain credit reserves that we believe represent probable credit losses that will result from inherent losses existing in our consolidated real estate loans held-for-investment as of the date of the financial statements. The reserves for credit losses are adjusted by taking provisions for credit losses recorded as a reduction in interest income on real estate loans on our Consolidated Statements of Income. The reserves consist of estimates of specific loan impairment and estimates of collective losses on pools of loans with similar characteristics.
To calculate the credit reserve for credit losses for real estate loans, we determine inherent losses by applying loss factors (default, the timing of defaults, and the loss severity upon default) that can be specifically applied to each pool of loans. The following factors are considered and applied in such determination:
•  Ongoing analysis of the pool of loans, including, but not limited to, the age of the loans, underwriting standards, business climate, economic conditions, geographic considerations, and other observable data;
 
•  Historical loss rates and past performance of similar loans;
 
•  Relevant environmental factors;
 
•  Relevant market research and publicly available third-party reference loss rates;
 
•  Trends in delinquencies and charge-offs;
 
•  Effects and changes in credit concentrations;
 
•  Information supporting borrowers’ ability to meet obligations;

66


Table of Contents

•  Ongoing analyses of each individual loan — including, but not limited to, the age of loans, underwriting standards, business climate, economic conditions, geographical considerations and other observable data;
 
•  Ongoing evaluation of fair values of collateral using current appraisals and other valuations; and,
 
•  Discounted cash flow analyses.
Once we determine the applicable default rate, the timing of defaults, and the severity of loss upon the default, we estimate the expected losses of each pool of loans over their expected lives. We then estimate the timing of these losses and the losses probable to occur over an effective loss confirmation period. This period is defined as the range of time between the probable occurrence of a credit loss (such as the initial deterioration of the borrower’s financial condition) and the confirmation of that loss (the actual charge-off of the loan). After further review, we revised and shortened our estimate of this confirmation in the second quarter of 2006. The losses expected to occur within the estimated loss confirmation period are the basis of our credit reserves because we believe those losses exist as of the reported date of the financial statements. We re-evaluate the level of our credit reserves on at least a quarterly basis and record provision, charge-offs, and recoveries monthly.
If a loan becomes REO or becomes impaired, or loans are reclassified as held-for-sale, specific valuations are primarily based on analyses of the underlying collateral.
Certain securities issued by an ABS securitization entity bear most of the initial credit risk of the underlying pool of loans that was securitized. As a result of the relatively high credit risks of these investments, we are able to purchase these securities at a discount to principal (par) value. A portion of the purchase discount is subsequently accreted as interest income under the interest method while the remaining portion of the purchase discount is considered as a form of credit protection. The amount of credit protection is based upon our assessment of various factors affecting our assets, including economic conditions, characteristics of the underlying loans, delinquency status, past performance of similar loans, and external credit protection. We use a variety of internal and external credit risk analyses, cash flow modeling, and portfolio analytical tools to assist us in our assessments. If cumulative credit losses in the underlying pool of loans exceed the principal value of the first-loss piece, we may never receive a principal payment from that security. The maximum loss for the owner of these securities, however, is limited to the investment made in purchasing these securities. In addition to the amount of losses, the timing of future credit losses is also important. In general, the longer credit losses are delayed, the better our economic returns, as we continue to earn coupon interest on the face value of our security.
Accounting for Derivative Instruments
We use derivative instruments to manage certain risks such as market value risk and interest rate risk. The derivative instruments we employ include, but are not limited to, interest rate swaps, interest rate options, options on swaps, futures contracts, options on futures contracts, options on forward purchases, and other similar derivatives. We collectively refer to these derivative instruments as “interest rate agreements.”
On the date an interest rate agreement is entered into, we designate each interest rate agreement under GAAP as (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge), (2) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge), or (3) held for trading (trading instrument).
We currently elect to account for most of our interest rate agreements as cash flow hedges. We record these derivatives at their estimated fair market values, and record changes in their fair values in accumulated other comprehensive income on our Consolidated Balance Sheets. These amounts are reclassified to our Consolidated Statements of Income over the effective hedge period as the hedged item affects earnings. Any ineffective portions of these cash flow hedges and are included in our Consolidated Statements of Income.
The remainder of our interest rate agreements are currently accounted for as trading investments. We record these derivatives at their estimated fair values with any changes in the fair values recorded in our Consolidated Statements of Income.
