Note 1. Redwood Trust

Redwood Trust, Inc., together with its subsidiaries (“Redwood,” “we,” or “us”), invests in, finances, and manages real estate assets. We invest in residential and commercial loans and in asset-backed securities backed by real estate loans. We seek to invest in assets that have the potential to generate sufficient long-term cash flow returns to 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”).

Redwood was incorporated in the State of Maryland on April 11, 1994, and commenced operations on August 19, 1994. Our executive offices are located at One Belvedere Place, Suite 300, Mill Valley, California 94941.

Note 2. Basis of Presentation

The consolidated financial statements presented herein are at June 30, 2012 and December 31, 2011, and for the three and six months ended June 30, 2012 and 2011. These consolidated financial statements have been prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States of America — as prescribed by the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) — and using the Securities and Exchange Commission’s (“SEC”) instructions to Form 10-Q.

Organization

Our consolidated financial statements include the accounts of Redwood, its direct and indirect wholly-owned subsidiaries, and other entities in which we have a controlling financial interest. All significant intercompany balances and transactions have been eliminated. Redwood’s consolidated subsidiaries include both qualifying REIT subsidiaries and taxable subsidiaries. References to the REIT include Redwood and its qualifying REIT subsidiaries, excluding taxable subsidiaries.

We sponsor two securitization programs. Our Sequoia program is used for the securitization of residential mortgage loans. References to Sequoia refer collectively to all the consolidated Sequoia securitization entities. Our Acacia program was used for the securitization of mortgage-backed securities and other types of financial assets. References to Acacia refer collectively to all the consolidated Acacia securitization entities.

Principles of Consolidation

We apply FASB guidance to determine whether we must consolidate transferred financial assets and variable interest entities (“VIEs”) for financial reporting purposes. We currently consolidate the assets and liabilities of the Sequoia and the Acacia securitization entities where we maintain an ongoing involvement, as well as an entity formed in connection with a resecuritization transaction we engaged in during 2011 (“Resecuritization”). Prior to the fourth quarter of 2011, we also consolidated the assets, liabilities, and noncontrolling interests of the Opportunity Fund (“Fund”) that we managed. Each securitization entity is independent of Redwood and of each other and the assets and liabilities are not owned by and are not legal obligations of Redwood, although we are exposed to certain financial risks associated with our role as the sponsor or manager of these entities.

For financial reporting purposes, the underlying loans and securities owned at the Sequoia entities, Acacia entities, and Resecuritization entity are shown under residential and commercial loans and real estate securities on our consolidated balance sheets. The asset-backed securities (“ABS”) issued to third parties by these entities are shown under ABS issued. In our consolidated statements of income, we record interest income on the loans and securities owned at these entities and interest expense on the ABS issued by these entities. We also recorded interest income on the securities owned at the Fund and any income attributable to noncontrolling interest holders during prior periods.

See Note 4 for further discussion on principles of consolidation.

Note 3. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements requires us to make a number of significant estimates. These include estimates of fair value of certain assets and liabilities, amount and timing of credit losses, prepayment rates, and other estimates 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., valuation changes due to supply and demand, credit performance, prepayments, interest rates, or other reasons) will occur in the near term. Our estimates are inherently subjective in nature and actual results could differ from our estimates and the differences could be material.

Fair Value Measurements

Our financial statements include assets and liabilities that are measured at their estimated fair values in accordance with GAAP. A fair value measurement represents the price at which an orderly transaction would occur between willing market participants at the measurement date. We develop fair values for financial assets or liabilities based on available inputs and pricing that is observed in the marketplace. Examples of market information that we attempt to obtain include the following:

After considering all available indications of the appropriate rate of return that market participants would require, we consider the reasonableness of the range indicated by the results to determine an estimate that is most representative of fair value.

The markets for many of the loans and securities that we invest in and issue are generally illiquid. Establishing fair values for illiquid assets and liabilities is inherently subjective and is often dependent upon our estimates and modeling assumptions. If we determine that either the volume and/or level of trading activity for an asset or liability has significantly decreased from normal market conditions, or price quotations or observable inputs are not associated with orderly transactions, the market inputs that we obtain might not be relevant. For example, broker or pricing service quotes might not be relevant if an active market does not exist for the financial asset or liability. The nature of the quote (for example, whether the quote is an indicative price or a binding offer) is also evaluated.

In circumstances where relevant market inputs cannot be obtained, increased analysis and management judgment are required to estimate fair value. This generally requires us to establish internal assumptions about future cash flows and appropriate risk-adjusted discount rates. Regardless of the valuation inputs we apply, the objective of fair value measurement is unchanged from what it would be if markets were operating at normal activity levels and/or transactions were orderly; that is, to determine the current exit price.

See Note 5 for further discussion on fair value measurements.

Note 3. Summary of Significant Accounting Policies — (continued)

Fair Value Option

We have the option to measure eligible financial assets, financial liabilities, and commitments at fair value on an instrument-by-instrument basis. This option is available when we first recognize a financial asset or financial liability or enter into a firm commitment. Subsequent changes in the fair value of assets, liabilities, and commitments where we have elected the fair value option are recorded in our consolidated statements of income.

Our decision to apply the fair value option for new financial instruments is generally based upon our funding strategy for the specific financial asset acquired. For example, securities that we anticipate funding with equity will generally be accounted for as available-for-sale (“AFS”) securities. Securities that we anticipate funding with a combination of debt and equity or those financed through the issuance of asset-backed liabilities will generally be accounted for in a manner consistent with the associated liabilities. Additionally, we may elect to apply the fair value option for financial instruments that may not perform similarly to our traditional real estate investments or are particularly volatile or complex in structure.

See Note 5 for further discussion on the fair value option.

Residential and Commercial Loans

Residential and Commercial Loans — Fair Value

Residential and commercial loans at fair value include loans where we have elected the fair value option. Coupon interest is recognized as revenue when earned and deemed collectible or until a loan becomes more than 90 days past due. Changes in fair value are recurring and are reported through our consolidated statements of income in other market valuation adjustments, net.

Residential and Commercial Loans — Held-for-Sale

Residential and commercial loans held-for-sale include loans that we are marketing for sale to third parties, including transfers to securitization entities that we plan to sponsor and expect to be accounted for as sales for financial reporting purposes. These loans are carried at the lower of their cost or fair value, as measured on an individual basis or, in the case of the loans we intend to pool for securitization based upon similar underwriting characteristics, on an aggregate basis. If the fair value of an individual loan or pool of loans held-for-sale is lower than its amortized cost basis, this difference is reported as a negative market valuation adjustment through our consolidated statements of income. Coupon interest for loans held-for-sale is recognized as revenue when earned and deemed collectible or until a loan becomes more than 90 days past due. Gains or losses on the sale of residential or commercial loans are based on the specific identification method for loans measured on an individual basis or in aggregate for those loans measured on a pool basis.

Residential and Commercial Loans — Held-for-Investment

Loans held-for-investment include residential loans owned at Sequoia entities and commercial loans owned by us and net of any allowance for loan losses. Coupon interest is recognized as revenue when earned and deemed collectible or until a loan becomes more than 90 days past due or has been individually impaired, at which point the loan is placed on nonaccrual status. Interest previously accrued for loans that have become greater than 90 days past due or individually impaired is reserved for in the allowance for loan losses. Residential loans delinquent more than 90 days or in foreclosure are characterized as seriously delinquent. Cash principal and interest that is advanced from servicers subsequent to a loan becoming greater than 90 days past due or individually impaired is used to reduce the outstanding loan principal balance. When a seriously delinquent loan previously placed on nonaccrual status has cured, meaning all delinquent principal and interest have been remitted by the borrower, the loan is placed back on accrual status. Alternately, loans that have been individually impaired may be placed back on accrual status if restructured and after the loan is considered reperforming. A restructured loan is considered reperforming when the loan has been current for at least 12 months.

Note 3. Summary of Significant Accounting Policies — (continued)

We use the interest method to determine an effective yield to amortize the premium or discount on real estate loans held-for-investment. For residential loans acquired prior to July 1, 2004, we use coupon interest rates as they change over time and anticipated principal payments to determine periodic amortization. For residential 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, if any, to determine periodic amortization.

We reclassify loans held-for-investment as loans held-for-sale if we determine that these loans will be sold or transferred to third parties. This may occur, for example, if we exercise our right to call ABS issued by a Sequoia securitization trust and decide to subsequently sell the underlying loans to third parties.

See Note 6 for further discussion on residential loans. See Note 7 for further discussion on commercial loans.

Residential Loans — Allowance for Loan Losses

For residential loans classified as held-for-investment, we establish and maintain an allowance for loan losses based on our estimate of credit losses inherent in our loan portfolios at the reporting date. To calculate the allowance for loan losses, 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 loan or pools of loans.

We consider the following factors in evaluating the allowance for loan losses:

Once we determine the amount of defaults, the timing of the defaults, and severity of losses upon the defaults, we estimate expected losses for each individual loan or pool of loans over its expected life. We then estimate the timing of these losses and the losses probable to occur over an appropriate loss confirmation period. This period is defined as the range of time between the 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 allowance for loan losses, since we believe these losses exist at the reported date of the financial statements. We re-evaluate the adequacy of our allowance for loan losses quarterly.

As part of the loss mitigation efforts undertaken by servicers of residential loans owned by Sequoia securitization entities, a growing number of loan modifications have been completed to help make mortgage loans more affordable for certain borrowers. Loan modifications may include, but are not limited to: (i) conversion of a floating rate mortgage loan into a fixed rate mortgage loan; (ii) reduction in the contractual interest rate of a mortgage loan; (iii) forgiveness of a portion of the contractual interest and/or principal amounts owed on a mortgage loan; and, (iv) extension of the contractual maturity of a mortgage loan. We evaluate all loan modifications performed by servicers to determine if they constitute troubled debt restructurings (“TDRs”) according to GAAP. If a loan is determined to be a TDR, it is removed from the general loan pools used for

calculating allowances for loan losses and assessed for impairment on an individual basis based upon any adverse change in the expected future cash flows resulting from the modification. This difference is recorded to the reversal of (provision for) loan losses in our consolidated statements of income.

When foreclosed property is received in full satisfaction for a defaulted loan, we estimate the fair value of the property, based on estimated net proceeds from the sale of the property (including servicer advances and other costs). To the extent that the fair value of the property is below the recorded investment of the loan, we record a charge against the allowance for loan losses for the difference. Foreclosed property is subsequently recorded as real estate owned (“REO”), a component of other assets on our consolidated balance sheets. Actual losses incurred on loans liquidated through a short-sale are also charged against the allowance for loan losses.

Repurchase Reserves

We do not currently maintain a loan repurchase reserve and management is not aware of any outstanding repurchase claims that would require the establishment of such a reserve. We do not originate residential loans and believe that the risk of loss due to loan repurchases (i.e., due to a breach of representations and warranties) would generally be a contingency to the companies from whom we acquired the loans and therefore would be covered by our recourse to those companies.

In circumstances where we believe that there is a risk of loss due to a loan repurchase demand (i.e., due to an allegation of a breach of representations and warranties) and we do not believe that full recourse to the company from whom we acquired the loan exists or is enforceable, we will review the need for any loan repurchase reserve in accordance with FASB guidance on accounting for contingencies and establish reserves when, in the opinion of management, it is probable that a repurchase demand would result in a liability and the amount of loss, if any, can be reasonably estimated.

See Note 6 for further discussion on the allowance for loan losses for residential loans.

Commercial Loans — Allowance for Loan Losses

For commercial loans classified as held-for-investment, we establish and maintain a general allowance for loan losses inherent in our portfolio at the reporting date and, where appropriate, a specific allowance for loan losses for loans we have determined to be impaired at the reporting date. An individual loan is considered impaired when it is deemed probable that we will not be able to collect all amounts due according to the contractual terms of the loan.

Our methodology for assessing the adequacy the allowance for loan losses begins with a formal review of each commercial loan in the portfolio and the assignment of an internal impairment status. Reviews are performed at least quarterly. We consider the following factors in evaluating each loan:

Loan reviews are completed by asset management and finance personnel and reviewed and approved by senior management.

Note 3. Summary of Significant Accounting Policies — (continued)

Based on the assigned impairment status, a loan is categorized as “Pass,” “Watch List,” or “Workout.” Pass loans are defined as loans that are performing in accordance with the contractual terms of the loan agreement. Watch List loans are defined as performing loans for which the timing of cost recovery is under review. Workout loans are defined as loans that we believe have a credit impairment that may lead to a realized loss. Workout loans are typically assessed for impairment on an individual basis. Where an individual commercial loan is impaired, we record an allowance to reduce the carrying value of the loan to the current present value of expected future cash flows discounted at the loan’s effective rate, with a corresponding charge to our consolidated statement of income.

For all commercial loans that are not individually impaired, we assess the commercial loan portfolio in aggregate for loan losses based on our expectation of credit losses inherent in the portfolio at the reporting date. Our expectation of credit losses is informed by, among other things:

See Note 7 for further discussion on the allowance for loan losses for commercial loans.

Real Estate Securities, at Fair Value

We classify our real estate securities as trading or available-for-sale securities. We use the “prime” or “non-prime” designation to categorize our residential securities based upon the general credit characteristics of the residential loans underlying each security at the time of origination. For example, prime residential loans are generally characterized by lower loan-to-value (“LTV”) ratios at the time the loan was originated, and are made to borrowers with higher Fair Isaac Corporation (“FICO”) scores. Non-prime residential loans are generally characterized by higher LTV ratios at the time the loan was originated and may have been made to borrowers with lower credit scores or impaired credit histories (while exhibiting the ability to repay their loans) at the time the loan was originated. Regardless of whether or not the loans underlying a residential security were designated as prime or non-prime at origination, there is a risk that the borrower may not be able to repay the loan.

Trading Securities

Trading securities may include residential, commercial, and collateralized debt obligation (“CDO”) securities. Trading securities are carried at their estimated fair values. Coupon interest is recognized as interest income when earned and deemed collectible. All changes in fair value are reported through our consolidated statements of income in other market valuation adjustments, net.

We primarily denote trading securities as those securities where we have adopted the fair value option. We currently account for certain securities at Redwood and all securities at consolidated Acacia entities as trading securities, at fair value.

AFS Securities

AFS securities may include certain residential, commercial, and CDO securities. AFS securities are carried at their estimated fair values with cumulative unrealized gains and losses reported as a component of accumulated other comprehensive income in our consolidated statements of changes in equity. Coupon interest is recognized as interest income when earned and deemed collectible, and the interest method is used to determine an effective yield to amortize purchase premiums, discounts, and fees associated with these securities into income over time. This requires us to project cash flows over the remaining life of each security and make assumptions with regards to interest rates, prepayment rates, the timing and amount of credit losses, 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.

Note 3. Summary of Significant Accounting Policies — (continued)

For an AFS security where its estimated fair value at the reporting date is below its amortized cost basis, we evaluate the security for other-than-temporary impairment (“OTTI”). If we either — (i) intend to sell the impaired security; (ii) will more likely than not be required to sell the impaired security before it recovers in value; or, (iii) do not expect to recover the impaired security’s amortized cost basis even if we do not intend to sell the security — the impairment is deemed an OTTI and we record the entire difference between the security’s fair value and its amortized cost in our consolidated statements of income. Conversely, if none of these three conditions are met, we analyze the expected cash flows, or cost recovery of the security, to determine what, if any, OTTI is recognized through our consolidated statements of income. This analysis includes an assessment of any changes in the regulatory and/or economic environment that might affect the performance of the security.

If we conclude through our analysis that there has been no significant adverse change in our cash flow assumptions for the security, then the impairment is deemed temporary in nature and the associated difference between the security’s fair value and its amortized cost basis is recorded as an unrealized loss through accumulated other comprehensive income, a component of equity. Alternatively, if we conclude that there has been a significant adverse change in our cash flow assumptions for the security, then the impairment is deemed an OTTI and we perform an additional analysis to determine what portion of OTTI, if any, should be recorded through our consolidated statements of income. This analysis entails discounting the security’s cash flows to a present value using the prior period yield for the security to determine an “expected recoverable value.” The difference between this expected recoverable value and the amortized cost basis of the security is deemed to be the “credit” component of the OTTI that is recorded in our consolidated statements of income. The amortized cost of the security is then adjusted to the expected recoverable value, and the difference between this expected recoverable value and the estimated fair value is deemed to be the “non-credit” component of the OTTI and is recorded to accumulated other comprehensive income. Future amortization and accretion for the security is computed based upon the new amortized cost basis.

See Note 8 for further discussion on real estate securities.

Cash and Cash Equivalents

Cash and cash equivalents include non-restricted cash and highly liquid investments with original maturities of three months or less. At June 30, 2012, we did not have any significant concentrations of credit risk arising from cash deposits as all of our cash and cash equivalents were invested in FDIC-insured bank products.

Restricted Cash

Restricted cash primarily includes principal and interest payments that are collateral for, or payable to, owners of ABS issued by consolidated securitization entities. Restricted cash may also include cash retained in the Acacia or Sequoia securitization entities or in the resecuritization entity prior to the payments on or redemptions of outstanding ABS issued. At June 30, 2012, we did not have any significant concentrations of credit risk arising from restricted cash deposits as all of our restricted cash was held in custodial accounts or FDIC-insured bank products.

Accrued Interest Receivable

Accrued interest receivable includes interest that is due and payable to us. Cash interest is generally received within thirty days of recording the receivable. For financial assets where we have elected the fair value option, the associated accrued interest on these assets is measured at fair value. For financial assets where we have not elected the fair value option, the associated accrued interest carrying values approximate fair values.

Derivative Financial Instruments

Derivative financial instruments we currently utilize include contractual interest rate agreements, financial futures contracts, and “To Be Announced” (“TBA”) contracts. All derivative financial instruments are recorded at fair value in our consolidated balance sheets. Derivatives with positive fair values to us are reported as assets and derivatives with negative fair values to us are reported as liabilities. We classify each of our derivative financial

instruments as either (i) a trading instrument (no specific hedging designation for financial reporting purposes) or (ii) 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).

Changes in the fair values of derivatives accounted for as trading instruments, including any associated interest income or expense, are recorded in our consolidated statements of income through other market valuation adjustments, net. The valuation changes related to derivatives used to manage certain risks associated with the residential loans we own or plan to acquire and sell or securitize are excluded from other market valuation adjustments, net, and included in mortgage banking activities, net, on our consolidated statements of income. Changes in the fair values of derivatives accounted for as cash flow hedges, to the extent they are effective, are recorded in accumulated other comprehensive income, a component of equity. Interest income or expense, and any ineffectiveness associated with these derivatives, are recorded as a component of net interest income in our consolidated statements of income. We measure the effective portion of cash flow hedges by comparing the change in fair value of the expected future variable cash flows of the derivative hedging instruments with the change in fair value of the expected future variable cash flows of the hedged liability.

We will discontinue cash flow hedge accounting if (i) we determine that the hedging derivative is no longer expected to be effective in offsetting changes in the cash flows of the designated hedged item; (ii) the derivative expires or is sold, terminated, or exercised; (iii) the derivative is de-designated as a cash flow hedge; or, (iv) it is probable that a forecasted transaction associated with the hedged item will not occur by the end of the originally specified time period. To the extent we de-designate a cash flow hedging relationship and the associated hedged item continues to exist, any unrealized gain or loss of the cash flow hedge at the time of de-designation remains in accumulated other comprehensive income and is amortized using the straight-line method through interest expense over the remaining life of the hedged liability.

Interest Rate Agreements

Interest rate agreements that we currently utilize include swaps, swaptions, and caps. Interest rate swaps are agreements in which (i) one counterparty exchanges a stream of fixed interest payments for another counterparty’s stream of variable interest cash flows; or, (ii) each counterparty exchanges variable interest cash flows that are referenced to different indices. Interest rate swaptions are agreements that provide the owner the right but not the obligation to enter into an underlying interest rate swap with a counterparty in the future. Interest rate caps are agreements in which the owner receives payments at the end of each period for which the prevailing interest rate exceeds an agreed upon strike price. We enter into interest rate agreements primarily to reduce significant changes in our income or equity caused by interest rate volatility. Certain of these interest rate agreements may be designated as cash flow hedges.

Eurodollar Futures, Treasury Futures, and TBA Contracts

Eurodollar futures are futures contracts on time deposits denominated in U.S. dollars at banks outside the United States. Eurodollar futures, unlike our other derivatives, have maturities of only three months. Therefore, in order to achieve the desired interest rate offset necessary to manage our risk, consecutively maturing contracts are required, resulting in a stated notional amount that is typically higher than our other derivatives. Treasury futures are futures contracts on benchmark U.S. Treasury rates. TBA contracts are forward contracts to purchase mortgage-backed securities that will be issued by a U.S. government sponsored enterprise (“GSE”) in the future. We purchase or sell these derivatives to offset — to varying degrees — changes in the values of mortgage products for which we have exposure.

See Note 9 for further discussion on derivative financial instruments.

Deferred Tax Assets

Our deferred tax assets are generated by temporary differences in GAAP and taxable income at our taxable subsidiaries. These differences generally reflect differing accounting treatments for tax and GAAP, such as

13

Table of Contents

REDWOOD TRUST, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 3. Summary of Significant Accounting Policies — (continued)

accounting for discount and premium amortization, credit losses, equity awards, asset impairments, and certain valuation estimates. As a result of these differences, we may recognize taxable income in periods prior to when we recognize income for GAAP. When this occurs, we pay the tax liability and establish a deferred tax asset for GAAP. As the income is subsequently realized in future periods under GAAP, the deferred tax asset is reduced. We did not have a deferred tax asset at June 30, 2012 or December 31, 2011.

Deferred Securities Issuance Costs

Securities issuance costs are expenses associated with the issuance of long-term debt, the resecuritization we engaged in during 2011, and the ABS from the Sequoia securitization entities we sponsor and consolidate for financial reporting purposes. These expenses typically include underwriting, rating agency, legal, accounting, and other fees. ABS issuance costs associated with liabilities accounted for under the fair value option are expensed as incurred. ABS issuance costs associated with liabilities reported at cost are deferred. Deferred securities issuance costs are reported on our consolidated balance sheets as deferred charges (an asset) and are amortized as an adjustment to interest expense using the interest method, based upon the actual and estimated repayment schedules of the related securities issued.

Other Assets

Other assets include mortgage servicing rights (“MSRs”), REO, margin receivable, fixed assets, principal receivable, and other prepaid expenses. REO property acquired through, or in lieu of, foreclosure is initially recorded at fair value, and subsequently reported at the lower of its carrying amount or fair value (less estimated cost to sell). Changes in the fair value of an REO property that has a fair value at or below its carrying amount are recorded in our consolidated statements of income as a component of other market valuation adjustments, net. Margin receivable reflects cash collateral we have posted with various counterparties relating to our derivative and lending agreements with those counterparties, as applicable.

See Note 10 for further discussion on other assets.

MSRs

We recognize MSRs through the acquisition of servicing rights released by third parties or through the retention of MSRs associated with residential loans that we have acquired and subsequently transferred to third parties. Typically, our MSRs are directly acquired from loan originators or created through the transfer of loans to a Sequoia residential securitization sponsored by us that meets the GAAP criteria for sale accounting.

Our MSRs are held and managed at Redwood Residential Acquisition Corporation, a wholly-owned subsidiary of RWT Holdings, Inc., which is a taxable REIT subsidiary of ours. MSRs are initially recognized and carried at their estimated fair values. Changes in the fair value of MSRs are reported in mortgage banking activities, net, a component of our consolidated statements of income.

See Note 17 for further discussion on MSRs.

Short-Term Debt

Short-term debt includes borrowings under master repurchase agreements and other forms of borrowings that expire within one year with various counterparties. These facilities may be unsecured or collateralized by cash, loans, or securities.

See Note 11 for further discussion on short-term debt.

Accrued Interest Payable

Accrued interest payable includes interest that is due and payable to third parties. Interest is generally paid within one to three months of recording the payable, based upon our remittance requirements. For borrowings where
