Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Significant Accounting Policies Fair Value Measurements Our consolidated 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. 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 assets 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 for assets 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. 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. We elect the fair value option for certain residential loans, interest-only (“IO”) and certain subordinate securities, and MSRs. We generally elect the fair value option for residential loans that are held-for-sale, due to our intent to sell or securitize the loans in the near-term. We elect the fair value option for our IO and certain subordinate securities, and MSRs, for which we generally hedge market interest rate risk. As such, we seek to offset interest rate related changes in the values of these investments with changes in the values of their associated hedges through our consolidated statements of income. In addition, we elect the fair value option for the assets and liabilities of our consolidated Sequoia entities in accordance with GAAP accounting for collateralized financing entities ("CFEs"). See Note 5 for further discussion on the fair value option. Real Estate Loans Residential Loans - Held-for-Sale at Fair Value Residential 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. We generally elect the fair value option for residential loans that we purchase with the intent to sell to third parties or transfer to Sequoia securitizations. Coupon interest is recognized as revenue when earned and deemed collectible or until a loan becomes more than 90 days past due, at which point the loan is placed on nonaccrual status. Changes in fair value are recurring and are reported through our consolidated statements of income in Mortgage banking activities, net. Residential Loans - Held-for-Sale at Lower of Cost or Market Loans held-for-sale at lower of cost or market include certain residential loans. These loans are recorded and subsequently reported at the lower of their initial carrying amount or current fair value. Coupon interest is recognized as revenue when earned and deemed collectible or until a loan becomes more than 90 days past due, at which point the loan is placed on nonaccrual status. Loans delinquent more than 90 days or in foreclosure are characterized as a serious delinquency. Cash principal and interest that is advanced from servicers subsequent to a residential loan becoming greater than 90 days past due is accounted for as a reduction in 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. Changes in fair value are non-recurring and are reported through our consolidated statements of income in Mortgage banking activities, net. Residential Loans Held-for-Investment - At Fair Value Certain loans that were originally purchased with the intent to sell as part of our residential mortgage banking operations, and for which we elected the fair value option at acquisition, were subsequently reclassified to held-for-investment ("HFI") when the loans were transferred to our FHLBC member subsidiary and pledged as collateral for borrowings made from the Federal Home Loan Bank of Chicago (“FHLBC”). As of December 31, 2017, our current intent is to hold these loans for longer-term investment while they are financed by the FHLBC. In addition, we record loans held at consolidated Sequoia entities at fair value. In accordance with accounting guidance for CFEs, we use the fair value of the ABS issued by the Sequoia entities (which we determined to be more observable) to determine the fair value of the loans held at these entities. Coupon interest for these loans is recognized as revenue when earned and deemed collectible or until a loan becomes more than 90 days past due, at which point the loan is placed on nonaccrual status. 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. Changes in fair value are recurring and are reported through our consolidated statements of income in Investment fair value changes, net. Repurchase Reserves We sell and have sold residential mortgage loans to various parties, including (1) securitization trusts, (2) Fannie Mae and Freddie Mac (“the Agencies”), and (3) banks and other financial institutions that purchase mortgage loans for investment or private label securitization. We may be required to repurchase residential mortgage loans we have sold, or loans associated with MSRs we have purchased, in the event of a breach of specified contractual representations and warranties made in connection with these sales and purchases. With respect to MSRs we purchased, if the associated residential loan was sold to one of the Agencies (which was typically the case), that Agency can require us, as the owner of the MSR, to repurchase the residential loan in the event of such a breach of representations and warranties even though we were not the party that sold the associated loan to that Agency. In January 2016, we discontinued the acquisition and aggregation of conforming loans for resale to the Agencies. We do not originate residential mortgage loans and believe the initial 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 or MSRs. However, in some cases, such as where loans or MSRs were acquired from companies that have since become insolvent, we may have to bear the loss associated with a loan repurchase. Furthermore, even if we do not have to ultimately bear such a loss because we can recover from the company that sold us the loan or the MSR, there could be a delay in making that recovery. We establish reserves for mortgage repurchase liabilities related to various representations and warranties that reflect management’s estimate of losses for loans for which we could have a repurchase obligation, based on a combination of factors. Such factors can include estimated future defaults and loan repurchase rates, the potential severity of loss in the event of defaults, and the probability of our being liable for a repurchase obligation. We establish a reserve at the time loans are sold and MSRs are purchased and continually update our reserve estimate during its life. The reserve for mortgage loan repurchase losses is included in other liabilities on our consolidated balance sheets and the related expense is included as a component of Mortgage banking activities, net and MSR income (loss), net on our consolidated statements of income. See Note 14 for further discussion on the residential repurchase reserves. Real Estate Securities, at Fair Value Our securities primarily consist of residential mortgage backed securities (“RMBS”) and may include other residential and commercial securities. We classify our real estate securities as trading or available-for-sale securities. Nearly all of our securities are supported by collateral designated as prime at the time of issuance. Prime residential loans are generally characterized by lower loan-to-value (“LTV”) ratios at the time the loans were originated, and are made to borrowers with higher Fair Isaac Corporation (“FICO”) scores. Trading Securities We primarily denote trading securities as those securities where we have adopted the fair value option. Trading securities are carried at their estimated fair values. Coupon interest is recognized as interest income when earned and deemed collectible. Changes in the fair value of securities designated as trading securities are reported in Investment fair value changes, net on our consolidated statements of income. Available-for-Sale Securities AFS securities are carried at their estimated fair value with unrealized gains and losses excluded from earnings (except when an other-than-temporary impairment (“OTTI”) is recognized, as discussed below) and reported in Accumulated other comprehensive income (“AOCI”), a component of stockholders’ equity. Interest income on AFS securities is accrued based on their outstanding principal balance and contractual terms and interest income is recognized based on the security’s effective interest rate. In order to calculate the effective interest rate, we must 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. On at least a quarterly basis, we review and, if appropriate, make adjustments to our cash flow projections based on input and analysis received from external sources, internal models, and our own judgments about interest rates, prepayment rates, the timing and amount of credit losses, and other factors. Changes in cash flows from those originally projected, or from those estimated at the last evaluation, may result in a prospective change in the yield and interest income recognized on these securities or in the recognition of OTTI as discussed below. For AFS securities purchased and held at a discount, a portion of the discount may be designated as non-accretable purchase discount (“credit reserve”), based on the cash flows we have projected for the security. The amount designated as credit reserve may be adjusted over time, based on our periodic evaluation of projected cash flows. If the performance of a security with a credit reserve is more favorable than previously forecasted, a portion of the credit reserve may be reallocated to accretable discount and recognized into interest income over time. Conversely, if the performance of a security with a credit reserve is less favorable than forecasted, the amount designated as credit reserve may be increased, or impairment charges and write-downs of such securities to a new cost basis could result. When the fair value of an AFS security is less than its amortized cost at the reporting date, the security is considered impaired. We assess our impaired securities at least quarterly to determine if the impairment is temporary or other-than-temporary (resulting in an 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) if there has been an adverse change in cash flows - the impairment is deemed an OTTI. In the case of criteria (i) and (ii), we record the entire difference between the security’s estimated fair value and its amortized cost at the reporting date as an impairment through market valuation adjustments on our consolidated statements of income. If there has been an adverse change in cash flows, only the portion of the OTTI related to “credit” losses is recognized through other market valuation adjustments on our consolidated statements of income, with the remaining “non-credit” portion recognized through AOCI on our consolidated balance sheets. If the first two criteria are not met and there has not been an adverse change in cash flows, the impairment is considered temporary and the entire unrealized loss is recognized through AOCI on our consolidated balance sheets. For impaired AFS securities, to determine if there has been an adverse change in cash flows and if any portion of a resulting OTTI is related to credit losses, we compare the present value of the cash flows expected to be collected as of the current financial reporting date to the amortized cost basis of the security. The discount rate used to calculate the present value of expected future cash flows is the current yield used for income recognition purposes. If the present value of the current expected cash flows is less than the amortized cost basis, there has been an adverse change and the security is considered OTTI with the difference between these two amounts representing the credit loss. The determination as to whether an OTTI exists and, if so, the amount of credit impairment recognized in earnings is subjective, and based on information available at the time of the assessment as well as our estimates of future performance and cash flows. As a result, the timing and amount of OTTI constitute a material estimate that is susceptible to significant change. See Note 7 for further discussion on real estate securities. MSRs We recognize MSRs through the retention of servicing rights associated with residential mortgage loans that we acquired and subsequently transferred to third parties when the transfer meets the GAAP criteria for sale accounting, or through the direct acquisition of MSRs sold by third parties. We contract with licensed sub-servicers to perform servicing functions for loans associated with our MSRs. We have elected the fair value option for all of our MSRs, and they are initially recognized and subsequently carried at their estimated fair values. Servicing fee income from MSRs is recorded on a cash basis when received. Net servicing income and changes in the estimated fair value of MSRs are reported in MSR income (loss), net on our consolidated statements of income. See Note 8 for further discussion on MSRs. Cash and Cash Equivalents Cash and cash equivalents include non-restricted cash and highly liquid investments with original maturities of three months or less. The Company maintains its cash and cash equivalents with major financial institutions. Accounts at these institutions are guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 for each bank. The Company is exposed to credit risk for amounts held in excess of the FDIC limit. The Company does not anticipate nonperformance by these institutions. Restricted Cash Restricted cash primarily includes cash held in association with borrowings from the Federal Home Loan Bank of Chicago, and cash associated with our risk-sharing transactions with the Agencies, as well as principal and interest payments that are collateral for, or payable to, owners of ABS issued by consolidated securitization entities. Accrued Interest Receivable Accrued interest receivable includes interest that is due and payable to us and deemed collectible. 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 receivable 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 typically utilize include swaps, swaptions, financial futures contracts, CMBX credit default index swaps, and “To Be Announced” (“TBA”) contracts. These derivatives are primarily used to manage interest rate risk associated with our operations. In addition, we enter into certain residential loan purchase commitments (“LPCs”) and residential loan forward sale commitments (“FSCs”) that are treated as derivatives for financial reporting purposes. All derivative financial instruments are recorded at their estimated fair value on 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 derivative 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 MSR income (loss), net if they are used to manage risks associated with our MSR investments, through Mortgage banking activities, net if they are used to manage risks associated with our mortgage banking activities, or through Investment fair value changes, net if they are used to manage risks associated with our investments. Valuation changes related to residential LPCs and FSCs are 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 on our consolidated balance sheets. 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 item. We will discontinue a designated cash flow hedge relationship 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 or terminate 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 item. Swaps and Swaptions 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. We enter into swap and swaptions 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 and Financial Futures 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. Financial futures are futures contracts on benchmark U.S. Treasury rates. TBA Agreements TBA agreements are forward contracts to purchase mortgage-backed securities that will be issued by a U.S. government sponsored enterprise 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 to interest rate volatility. Loan Purchase and Forward Sale Commitments We use the term LPCs to refer to agreements with third-party residential loan originators to purchase residential loans at a future date that qualify as a derivative under GAAP and we use the term FSCs to refer to agreements with third-parties to sell residential loans at a future date that also qualify as derivatives under GAAP. LPCs and FSCs are recorded at their estimated fair values on our consolidated balance sheets and changes in fair value are recurring and are reported through our consolidated statements of income in Mortgage banking activities, net. See Note 9 for further discussion on derivative financial instruments. Deferred Tax Assets and Liabilities Our deferred tax assets/liabilities are generated by temporary differences in GAAP and taxable income at our taxable subsidiaries. These differences generally reflect differing accounting treatments for GAAP and tax, such as accounting for mortgage servicing rights, discount and premium amortization, credit losses, 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 as required and establish a deferred tax asset. As the income is subsequently realized in future periods under GAAP, the deferred tax asset is reduced. We may also recognize GAAP income in periods prior to when we recognize income for tax. When this occurs, we establish a deferred tax liability for GAAP. As the income is subsequently realized in future periods for tax, the deferred tax liability is reduced. In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We consider historical and projected future taxable income and capital gains as well as tax planning strategies in making this assessment. We determine the extent to which realization of this deferred asset is not assured and establish a valuation allowance accordingly. The estimate of net deferred tax assets could change in future periods to the extent that actual or revised estimates of future taxable income during the carryforward periods change from current expectations. Other Assets and Other Liabilities Other assets primarily consists of margin receivable, FHLBC stock, MSR holdback receivable, pledged collateral, guarantee asset, and REO. Other liabilities primarily consists of accrued compensation, guarantee obligations, deferred tax liabilities, margin payable, and residential loan and MSR repurchase reserves. FHLBC Stock In accordance with its borrowing agreement with the FHLBC, our FHLB-member subsidiary is required to purchase and hold stock in the FHLBC in an amount equal to a specified percentage of outstanding advances. FHLBC stock is considered a non-marketable, long-term investment, and is carried at cost. Because this stock can only be redeemed or sold at its par value, and only to the FHLBC, carrying value, or cost, approximates fair value. Dividends received from FHLBC stock are recorded in other income, net in our consolidated statements of income. Margin Receivable and Payable Margin receivable and payable result from margin calls between us and our derivatives, master repurchase agreements, and warehouse facilities counterparties, whereby we or the counterparty were required to post collateral. Agency Risk-Sharing - Other Assets and Liabilities During 2014 and 2015, we entered into various risk-sharing arrangements with Fannie Mae and Freddie Mac. Under these arrangements, we committed to assume the first 1.00% or 2.25% (depending on the arrangement) of losses realized on reference pools of conforming residential mortgage loans that we acquired and then sold to the Agencies. As part of these risk-sharing arrangements, during the 10-year term of our first Fannie Mae arrangement, we receive monthly cash payments from Fannie Mae based on the monthly outstanding unpaid principal balance of the reference pool of loans, and for our Freddie Mac and our subsequent Fannie Mae arrangements, the Agencies charged us a reduced guarantee fee for the reference loans we delivered to them in exchange for mortgage backed securities, which we then sold. Under these arrangements we are required to pledge assets to the Agencies to collateralize our risk-sharing commitments to them throughout the terms of the arrangements. These pledged assets are held by a third-party custodian for the benefit of the Agencies. To the extent approved losses are incurred, the custodian will transfer collateral to the Agencies. As a result of these transactions, we recorded “pledged collateral” in the other assets line item, and “guarantee obligations” in the other liabilities line item, on our consolidated balance sheets. In addition, for the first Fannie Mae transaction, we recorded a “guarantee asset” in the other assets line item on our consolidated balance sheets. The guarantee obligations represent our commitments to assume losses under these arrangements. We amortize the guarantee obligations over the 10-year terms of the arrangements based primarily on changes in the outstanding unpaid principal balance of loans in the reference pools, with a portion of the liabilities treated as a credit reserve that is not amortized into income. In addition, each period we assess the need for a separate loss allowance related to these arrangements, based on our estimate of credit losses inherent in the reference pools of loans. Income from cash payments received under the first Fannie Mae risk-sharing arrangement and income related to the amortization of the guarantee obligations of all three arrangements are recorded in other income, and market valuation changes of the guarantee asset are recorded in Investment fair value changes, net on our consolidated statements of income. Our consolidated balance sheets include assets of the special purpose entities ("SPEs") associated with these risk-sharing arrangements (i.e., the "pledged collateral" referred to above) that can only be used to settle obligations of these SPEs and liabilities of these SPEs for which the creditors of these SPEs (the Agencies) do not have recourse to Redwood Trust, Inc. or its affiliates. At December 31, 2017 and December 31, 2016, assets of such SPEs totaled $48 million and $49 million, respectively, and liabilities of such SPEs totaled $19 million and $22 million, respectively. See Note 14 for further discussion on loss contingencies — risk-sharing. MSR Holdback Receivable MSR holdback receivable represents amounts due from third parties related to the sale of MSRs that will be received upon the final transfer of the related servicing documentation at the end of the holdback period. See Note 10 for further discussion on other assets. REO 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 Investment fair value changes, net on our consolidated statements of income. See Note 10 for further discussion on other assets. Short-Term Debt Short-term debt includes borrowings under master repurchase agreements, loan warehouse facilities, and other forms of borrowings that expire within one year with various counterparties. These borrowings are typically collateralized by cash, loans, or securities, and in some cases may be unsecured. If the value (as determined by the applicable counterparty) of the collateral securing those borrowings decreases, we may be subject to margin calls during the period the borrowings are outstanding. In instances where we do not satisfy the margin calls within the required time frame, the counterparty may retain the collateral and pursue any outstanding debt amount from us. 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, and is paid semi-annually for our convertible and exchangeable debt. Interest on our FHLB borrowings is paid every 13 weeks. For borrowings where we have elected the fair value option, the associated accrued interest on these liabilities is measured at fair value. For financial liabilities where we have not elected the fair value option, the associated accrued interest carrying values approximate fair values. Asset-Backed Securities Issued ABS issued represents asset-backed securities issued through the Legacy Sequoia and Sequoia Choice securitization entities. Assets at these entities are held in the custody of securitization trustees and are not owned by Redwood. These trustees collect principal and interest payments (less servicing and related fees) from the assets and make corresponding principal and interest payments to the ABS investors. In accordance with accounting guidance for CFEs, we account for the ABS issued under our consolidated Sequoia entities at fair value, with periodic changes in fair value recorded in Investment fair value changes, net on our consolidated statements of income. See Note 12 for further discussion on ABS issued. Long-Term Debt FHLBC Borrowings FHLBC borrowings include amounts borrowed by our FHLB-member subsidiary, also referred to as “advances,” from the Federal Home Loan Bank of Chicago that are secured by eligible collateral, including, but not limited to, residential mortgage loans and residential mortgage-backed securities. FHLBC borrowings are carried at their unpaid principal balance and interest on advances is paid every 13 weeks from when each respective advance is made. If the value (as determined by the FHLBC) of the collateral securing those borrowings decreases, we may be subject to margin calls during the period the borrowings are outstanding. In instances where we do not satisfy the margin calls within the required time frame, the FHLBC may foreclose upon the collateral and pursue any outstanding debt amount from us. Convertible Notes Convertible notes include unsecured convertible and exchangeable debt that are carried at their unpaid principal balance net of any unamortized deferred issuance costs. Interest on the notes is payable semiannually until such time the notes mature or are converted or exchanged into shares. If converted or exchanged by a holder, the holder of the notes would receive shares of our common stock. Trust Preferred Securities and Subordinated Notes Trust preferred securities and subordinated notes are carried at their unpaid principal balance net of any unamortized deferred issuance costs. This long-term debt is unsecured and interest is paid quarterly until it is redeemed in whole or matures at a future date. Deferred Debt Issuance Costs Deferred debt issuance costs are expenses associated with the issuance of long-term debt. These expenses typically include underwriting, rating agency, legal, accounting, and other fees. Deferred debt issuance costs are included in the carrying value of the related long-term debt issued and are amortized as an adjustment to interest expense using the interest method, based upon the actual and estimated repayment schedules of the related long-term debt issued. See Note 13 for further discussion on long-term debt. Equity Accumulated Other Comprehensive Income (Loss) Net unrealized gains and losses on real estate securities available-for-sale and interest rate agreements designated as cash flow hedges are reported as components of Accumulated other comprehensive income on our consolidated statements of changes in stockholders' equity and our consolidated balance sheets. Net unrealized gains and losses on securities and interest rate agreements held by our taxable subsidiaries that are reported in other comprehensive income are adjusted for the effects of taxation and may create deferred tax assets or liabilities. Earnings per Common Share Basic earnings per common share (“EPS”) is computed by dividing net income allocated to common shareholders by the weighted average common shares outstanding. Net income allocated to common shareholders represents net income less income allocated to participating securities (as described herein). Diluted EPS is computed by dividing income allocated to common shareholders by the weighted average common shares outstanding plus amounts representing the dilutive effect of share-based payment awards. In addition, if the assumed conversion or exchange of convertible or exchangeable debt into common shares is dilutive, diluted EPS is adjusted by adding back the periodic interest expense (net of any tax effects) associated with dilutive convertible or exchangeable debt to net income and adding the shares issued in an assumed conversion or exchange to the diluted weighted average share count. The two-class method is an earnings allocation formula under which EPS is calculated for common stock and participating securities according to dividends declared and participating rights in undistributed earnings. Under this method, all earnings (distributed and undistributed) are allocated between participating securities and common shares based on their respective rights to receive dividends or dividend equivalents. GAAP defines vested and unvested share-based payment awards containing nonforfeitable rights to dividends or dividend equivalents as participating securities that are included in computing EPS under the two-class method. See Note 15 for further discussion on equity. Incentive Plans In May 2014, our shareholders approved the 2014 Redwood Trust, Inc. Incentive Plan (“Incentive Plan”) for executive officers, employees, and non-employee directors, which replaced the 2002 Redwood Trust, Inc. Incentive Plan. The Incentive Plan provides for the grant of restricted stock, deferred stock, deferred stock units, performance-based awards (including performance stock units), dividend equivalents, stock payments, restricted stock units, and other types of awards to eligible participants. Long-term incentive awards granted under the Incentive Plan generally vest over a three- or four-year period. Awards made under the Incentive Plan to officers and other employees in lieu of the payment in cash of a portion of annual bonuses earned generally vest immediately, but are subject to a three-year mandatory holding period. Deferred stock units and restricted stock have attached dividend equivalent rights, resulting in the payment of dividend equivalents each time we pay a common stock dividend. Non-employee directors are also provided annual awards under the Incentive Plan that generally vest immediately. The cost of the awards is amortized over the vesting period on a straight-line basis. Upon adoption of ASU 2016-09 in 2016, we elected to begin accounting for forfeitures on employee equity awards as they occur. Employee Stock Purchase Plan In 2013, our shareholders approved an amendment to our previously amended 2002 Redwood Trust, Inc. Employee Stock Purchase Plan (“ESPP”) to increase the number of shares available under the ESPP. The purpose of the ESPP is to give our employees an opportunity to acquire an equity interest in the Company through the purchase of shares of common stock at a discount. The ESPP allows eligible employees to purchase common stock at 85% of its fair value, subject to certain limits. Fair value as defined under the ESPP is the lesser of the closing market price of the common stock on the first day of the calendar year or the last day of the calendar quarter. Executive Deferred Compensation Plan In 2013, our Board of Directors approved an amendment to our 2002 Executive Deferred Compensation Plan (“EDCP”) to allow non-employee directors to defer certain cash payments and dividends into DSUs. The EDCP allows eligible employees and directors to defer portions of current salary and certain other forms of compensation. The Company matches some deferrals. Compensation deferred under the EDCP is recorded as a liability on our consolidated balance sheets. The EDCP allows for the investment of deferrals in either an interest crediting account or DSUs. 401(k) Plan We offer a tax-qualified 401(k) Plan to all employees for retirement savings. Under this Plan, employees are allowed to defer and invest up to 100% of their cash earnings, subject to the maximum 401(k) Plan contribution limit set forth by the Internal Revenue Service. We match some employee contributions to encourage participation and to provide a retirement planning benefit to employees. Plan matching contributions made by the Company for the years ended December 31, 2017, 2016, and 2015 were $0.5 million, $0.6 million, and $0.8 million, respectively. Vesting of the 401(k) Plan matching contributions is based on the employee’s tenure at the Company, and over time an employee becomes increasingly vested in matching contributions. See Note 16 for further discussion on equity compensation plans. Taxes We have elected to be taxed as a REIT under the Internal Revenue Code and the corresponding provisions of state law. To qualify as a REIT we must distribute at least 90% of our annual REIT taxable income to shareholders (not including taxable income retained in our taxable subsidiaries) within the time frame set forth in the Internal Revenue Code and also meet certain other requirements related to assets, income, and stock ownership. We assess our tax positions for all open tax years and record tax benefits only if tax positions meet a more-likely-than-not threshold in accordance with GAAP guidance on accounting for uncertain tax positions. We classify interest and penalties on material uncertain tax positions as interest expense and operating expense, respectively, in our consolidated statements of income. See Note 20 for further discussion on taxes. Recent Accounting Pronouncements Newly Adopted Accounting Standards Updates ("ASUs") In January 2017, the FASB issued ASU 2017-03, "Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method and Joint Ventures (Topic 323)." This new guidance requires that companies evaluate ASUs that have not been adopted to determine the appropriate financial statement disclosures about the potential material effects of those ASUs on the financial statements when adopted. This new guidance was effective immediately. We adopted this guidance, as required, in the first quarter of 2017, which did not have a material impact on our consolidated financial statements. Other Recent Accounting Pronouncements In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." This new guidance amends previous guidance to better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. This new guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. We plan to adopt this new guidance by the required date and we are currently evaluating the impact that this update will have on our consolidated financial statements. In July 2017, the FASB issued ASU 2017-11, "Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception." This new guidance changes the classification analysis of certain equity-linked financial instruments (or embedded conversion options) with down round features. This new guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. We plan to adopt this new guidance by the required date and do not anticipate that this update will have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, "Compensation - Stock Compensation (Topic 718)." This new guidance provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. This new guidance is effective for fiscal years beginning after December 15, 2017, and should be applied prospectively to an award modified on or after the adoption date. Early adoption is permitted. We plan to adopt this new guidance by the required date and do not anticipate that this update will have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20)." This new guidance shortens the amortization period for certain callable debt securities purchased at a premium by requiring the premium to be amortized to the earliest call date. This new guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. We plan to adopt this new guidance by the required date and do not anticipate that this update will have a material impact on our consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash." This new guidance amends previous guidance on how to classify and present changes in restricted cash on the statement of cash flows. This new guidance is effective for fiscal years beginning after December 15, 2017. Early adoption is permitted. We plan to adopt this new guidance by the required date and we will modify the presentation of our cash flow statement as required. In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory." This new guidance allows an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. It also eliminates the exceptions for an intra-entity transfer of assets other than inventory. This new guidance is effective for fiscal years beginning after December 15, 2017. Early adoption is permitted. We plan to adopt this new guidance by the required date and do not anticipate that this update will have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments." This new guidance provides guidance on how to present and classify certain cash receipts and cash payments in the statement of cash flows. This new guidance is effective for fiscal years beginning after December 15, 2017. Early adoption is permitted. We plan to adopt this new guidance by the required date and do not anticipate that this update will have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses." This new guidance provides a new impairment model that is based on expected losses rather than incurred losses to determine the allowance for credit losses. This new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years beginning December 15, 2018. Currently, we have no financial instruments for which we maintain an allowance for loan losses. As such, based on our initial evaluation of this new guidance, we do not believe the provisions in this guidance will have a material impact to how we account for these instruments. Separately, we account for our available-for-sale securities under the other-than-temporary impairment ("OTTI") model for debt securities. This new guidance requires that credit impairments on our available-for-sale securities be recorded in earnings using an allowance for credit losses, with the allowance limited to the amount by which the security's fair value is less than its amortized cost basis. Subsequent reversals in credit loss estimates are recognized in income. We plan to adopt this new guidance by the required date and continue to evaluate the impact that this update will have on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases." This new guidance requires lessees to recognize most leases on their balance sheet as a right-of-use asset and a lease liability. This new guidance retains a dual lease accounting model, which requires leases to be classified as either operating or capital leases for lessees, for purposes of income statement recognition. This new guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. As discussed in Note 14, our only material leases are those related to our leased office space, for which future payments under these leases totaled $18 million at December 31, 2017. Upon adoption of this standard in the first quarter of 2019, we will record a right-of-use asset and lease liability equal to the present value of these future lease payments discounted at our incremental borrowing rate. Based on our initial evaluation of this new guidance, and taking into consideration our current in-place leases, we do not expect that its adoption will have a material impact on our consolidated financial statements. We will continue evaluating this new standard and caution that any changes in our business or additional leases we may enter into could change our initial assessment. In January 2016, the FASB issued ASU 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." This new guidance amends accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. This new guidance also amends certain disclosure requirements associated with the fair value of financial instruments and it is effective for fiscal years beginning after December 15, 2017. We plan to adopt this new guidance by the required date and do not anticipate that this update will have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” The update modifies the guidance companies use to recognize revenue from contracts with customers for transfers of goods or services and transfers of nonfinancial assets, unless those contracts are within the scope of other standards. The guidance also requires new qualitative and quantitative disclosures, including information about contract balances and performance obligations. In July 2015, the FASB approved a one-year deferral of the effective date. Accordingly, the update is effective for us in the first quarter of 2018 with retrospective application to prior periods presented or as a cumulative effect adjustment in the period of adoption. Early adoption was permitted in the first quarter of 2017. In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)." This new guidance provides additional implementation guidance on how an entity should identify the unit of accounting for the principal versus agent evaluations. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients," and in December 2016, the FASB issued ASU 2016-20, "Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers." These new ASUs provide more specific guidance on certain aspects of Topic 606. In September 2017, the FASB issued ASU 2017-13, "Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments (SEC Update)." This new ASU allows certain public business entities to use the nonpublic business entity effective dates for adoption of the new revenue standard. In November 2017, the FASB issued ASU 2017-14, "Income Statement - Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605), and Revenue from Contracts with Customers (Topic 606): Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 116 and SEC Release No. 33-10403." This new ASU amends various paragraphs that contain SEC guidance. The adoption of these accounting standards will not have a material impact on our consolidated financial statements, as financial instruments are explicitly scoped out of these standards and nearly all of our income is generated from financial instruments. Any changes in our business or additional amendments to these standards could change our initial assessment of these accounting standards. Balance Sheet Netting Certain of our derivatives and short-term debt are subject to master netting arrangements or similar agreements. Under GAAP, in certain circumstances we may elect to present certain financial assets, liabilities and related collateral subject to master netting arrangements in a net position on our consolidated balance sheets. However, we do not report any of these financial assets or liabilities on a net basis, and instead present them on a gross basis on our consolidated balance sheets. The table below presents financial assets and liabilities that are subject to master netting arrangements or similar agreements categorized by financial instrument, together with corresponding financial instruments and corresponding collateral received or pledged at December 31, 2017 and December 31, 2016.

(1) | Amounts presented in these columns are limited in total to the net amount of assets or liabilities presented in the prior column by instrument. In certain cases, there is excess cash collateral or financial assets we have pledged to a counterparty (which may, in certain circumstances, be a clearinghouse) that exceed the financial liabilities subject to a master netting arrangement or similar agreement. Additionally, in certain cases, counterparties may have pledged excess cash collateral to us that exceeds our corresponding financial assets. In each case, any of these excess amounts are excluded from the table although they are separately reported in our consolidated balance sheets as assets or liabilities, respectively.
(2) | Interest rate agreements, TBAs, credit default index swaps, and futures are components of derivatives instruments on our consolidated balance sheets. Loan warehouse debt, which is secured by residential mortgage loans, and security repurchase agreements are components of Short-term debt on our consolidated balance sheets.
For each category of financial instrument set forth in the table above, the assets and liabilities resulting from individual transactions within that category between us and a counterparty are subject to a master netting arrangement or similar agreement with that counterparty that provides for individual transactions to be aggregated and treated as a single transaction. For certain categories of these instruments, some of our transactions are cleared and settled through one or more clearinghouses that are substituted as our counterparty. References herein to master netting arrangements or similar agreements include the arrangements and agreements governing the clearing and settlement of these transactions through the clearinghouses. In the event of the termination and close-out of any of those transactions, the corresponding master netting agreement or similar agreement provides for settlement on a net basis. Any such settlement would include the proceeds of the liquidation of any corresponding collateral, subject to certain limitations on termination, settlement, and liquidation of collateral that may apply in the event of the bankruptcy or insolvency of a party. Such limitations should not inhibit the eventual practical realization of the principal benefits of those transactions or the corresponding master netting arrangement or similar agreement and any corresponding collateral.
