REDWOOD TRUST, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2017
(Unaudited)
Note 1. Organization
Redwood Trust, Inc., together with its subsidiaries, focuses on investing in mortgages and other real estate-related assets and engaging in mortgage banking activities. We seek to invest in real estate-related assets that have the potential to generate attractive cash flow returns over time and to generate income through our mortgage banking activities. We operate our business in two segments: Investment Portfolio and Residential Mortgage Banking. Redwood was incorporated in the State of Maryland on April 11, 1994, and commenced operations on August 19, 1994. References herein to “Redwood,” the “company,” “we,” “us,” and “our” include Redwood Trust, Inc. and its consolidated subsidiaries, unless the context otherwise requires.
Redwood Trust, Inc. has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), beginning with its taxable year ended December 31, 1994. We generally refer, collectively, to Redwood Trust, Inc. and those of its subsidiaries that are not subject to subsidiary-level corporate income tax as “the REIT” or “our REIT.” We generally refer to subsidiaries of Redwood Trust, Inc. that are subject to subsidiary-level corporate income tax as “our operating subsidiaries” or “our taxable REIT subsidiaries” or “TRS.”
We sponsor our Sequoia securitization program, which we use for the securitization of residential mortgage loans. References to Sequoia with respect to any time or period generally refer collectively to all the then consolidated Sequoia securitization entities for the periods presented. We have also engaged in securitization transactions in order to obtain financing for certain of our securities and commercial loans.
Note 2. Basis of Presentation
The consolidated financial statements presented herein are at September 30, 2017 and December 31, 2016, and for the three and nine months ended September 30, 2017 and 2016. These interim unaudited consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and note disclosures normally included in our annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") — as prescribed by the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) — have been condensed or omitted in these interim financial statements according to these SEC rules and regulations. Management believes that the disclosures included in these interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the company's Annual Report on Form 10-K for the year ended December 31, 2016. In the opinion of management, all normal and recurring adjustments to present fairly the financial condition of the company at September 30, 2017 and results of operations for all periods presented have been made. The results of operations for the three and nine months ended September 30, 2017 should not be construed as indicative of the results to be expected for the full year.
Principles of Consolidation
In accordance with GAAP, we 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 certain Sequoia securitization entities issued prior to 2012 where we maintain an ongoing involvement ("Legacy Sequoia"), as well as an entity formed in connection with the securitization of Redwood Choice expanded-prime loans during the third quarter of 2017 ("Sequoia Choice"). 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 Trust, Inc. Our exposure to these entities is primarily through the financial interests we have retained, although we are exposed to certain financial risks associated with our role as a sponsor, servicing administrator, or depositor of these entities or as a result of our having sold assets directly or indirectly to these entities.
For financial reporting purposes, the underlying loans owned at the consolidated Sequoia entities are shown under Residential loans, held-for-investment, at fair value 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 recorded interest income on the loans owned at these entities and interest expense on the ABS issued by these entities as well as other income and expenses associated with these entities' activities. See Note 12 for further discussion on ABS issued.
See Note 4 for further discussion on principles of consolidation.

Note 2. Basis of Presentation - (continued)
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, amounts 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 periods. 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.
Note 3. Summary of Significant Accounting Policies
Significant Accounting Policies
Included in Note 3 to the Consolidated Financial Statements of our 2016 Annual Report on Form 10-K is a summary of our significant accounting policies. Provided below is a summary of additional accounting policies that are significant to the company’s consolidated financial condition and results of operations for the three and nine months ended September 30, 2017.
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.
In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." This new guidance provides simplifications of the accounting for share-based payment transactions, including related income tax accounting, classification of awards, and classification on the statement of cash flows. In addition, this guidance permits the withholding of employee taxes related to the distribution of equity awards up to the maximum individual employee statutory tax rates. This new guidance is effective for fiscal years beginning after December 15, 2016 and early adoption is permitted. In the second quarter of 2016, we adopted this new guidance. Upon adoption, we elected to account for forfeitures on employee equity awards as they occur, rather than estimating expected forfeitures. The adoption of this guidance 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.

Note 3. Summary of Significant Accounting Policies - (continued)
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, a significant portion of our financial instruments are measured at fair value, for which we do not maintain any allowances for loan losses in accordance with fair value accounting. 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 changes the accounting for available-for-sale securities, including AFS securities purchased with credit deterioration. We are currently evaluating the impact that this update will have on our consolidated financial statements in regard to our available-for-sale securities. We plan to adopt this new guidance by the required date.
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 total $18 million at September 30, 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.

Note 3. Summary of Significant Accounting Policies - (continued)
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 is 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. Based on our initial evaluation of these new accounting standards, we do not expect that their adoption will have a material impact on our consolidated financial statements, as financial instruments are explicitly scoped out of the standards and nearly all of our income is generated from financial instruments. We will continue evaluating these new standards and caution that any changes in our business or additional amendments to these standards could change our initial assessment.
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 September 30, 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.

Note 4. Principles of Consolidation
GAAP requires us to consider whether securitizations we sponsor and other transfers of financial assets should be treated as sales or financings, as well as whether any VIEs that we hold variable interests in – for example, certain legal entities often used in securitization and other structured finance transactions – should be included in our consolidated financial statements. The GAAP principles we apply require us to reassess our requirement to consolidate VIEs each quarter and therefore our determination may change based upon new facts and circumstances pertaining to each VIE. This could result in a material impact to our consolidated financial statements during subsequent reporting periods.
Analysis of Consolidated VIEs
At September 30, 2017, we consolidated certain Legacy Sequoia securitization entities that we determined were VIEs and for which we determined we were the primary beneficiary. In addition, we consolidated the Sequoia Choice securitization entity beginning in the third quarter of 2017. Each of these entities is independent of Redwood and of each other and the assets and liabilities of these entities are not owned by and are not legal obligations of ours. Our exposure to these entities is primarily through the financial interests we have retained, although we are exposed to certain financial risks associated with our role as a sponsor, servicing administrator, or depositor of these entities or as a result of our having sold assets directly or indirectly to these entities. At September 30, 2017, the estimated fair value of our investments in the consolidated Legacy Sequoia entities and the Sequoia Choice entity was $19 million and $31 million, respectively. The following table presents a summary of the assets and liabilities of these VIEs.

Analysis of Unconsolidated VIEs with Continuing Involvement
Since 2012, we have transferred residential loans to 35 Sequoia securitization entities sponsored by us and accounted for these transfers as sales for financial reporting purposes, in accordance with ASC 860. We also determined we were not the primary beneficiary of these VIEs as we lacked the power to direct the activities that will have the most significant economic impact on the entities. For the transferred loans where we held the servicing rights prior to the transfer and continue to hold the servicing rights, we recorded MSRs on our consolidated balance sheets, and classified those MSRs as Level 3 assets. We also retained senior and subordinate securities in these securitizations that we classified as Level 3 assets. Our continuing involvement in these securitizations is limited to customary servicing obligations associated with retaining residential MSRs (which we retain a third-party sub-servicer to perform) and the receipt of interest income associated with the securities we retained.
The following table presents information related to securitization transactions that occurred during the three and nine months ended September 30, 2017 and 2016.

Analysis of Third-Party VIEs
Third-party VIEs are securitization entities in which we maintain an economic interest, but do not sponsor. Our economic interest may include several securities from the same third-party VIE, and in those cases, the analysis is performed in consideration of all of our interests. The following table presents a summary of our interests in third-party VIEs at September 30, 2017, grouped by security type.
Table 4.7 – Third-Party Sponsored VIE Summary

(Dollars in Thousands) |  | September 30, 2017
Mortgage-Backed Securities |  |
Senior |  | $ | 181,723 |
Re-REMIC |  | 39,033 |
Subordinate |  | 812,260 |
Total Investments in Third-Party Sponsored VIEs |  | $ | 1,033,016 |

We determined that we are not the primary beneficiary of any third-party VIEs, as we do not have the required power to direct the activities that most significantly impact the economic performance of these entities. Specifically, we do not service or manage these entities or otherwise solely hold decision making powers that are significant. As a result of this assessment, we do not consolidate any of the underlying assets and liabilities of these third-party VIEs – we only account for our specific interests in them.
Our assessments of whether we are required to consolidate a VIE may change in subsequent reporting periods based upon changing facts and circumstances pertaining to each VIE. Any related accounting changes could result in a material impact to our financial statements.

Note 5. Fair Value of Financial Instruments
For financial reporting purposes, we follow a fair value hierarchy established under GAAP that is used to determine the fair value of financial instruments. This hierarchy prioritizes relevant market inputs in order to determine an “exit price” at the measurement date, or the price at which an asset could be sold or a liability could be transferred in an orderly process that is not a forced liquidation or distressed sale. Level 1 inputs are observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2 inputs are observable inputs other than quoted prices for an asset or liability that are obtained through corroboration with observable market data. Level 3 inputs are unobservable inputs (e.g., our own data or assumptions) that are used when there is little, if any, relevant market activity for the asset or liability required to be measured at fair value.
In certain cases, inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, the level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. Our assessment of the significance of a particular input requires judgment and considers factors specific to the asset or liability being measured.

Note 5. Fair Value of Financial Instruments - (continued)
Determination of Fair Value
A description of the instruments measured at fair value as well as the general classification of such instruments pursuant to the Level 1, Level 2, and Level 3 valuation hierarchy is listed herein. We generally use both market comparable information and discounted cash flow modeling techniques to determine the fair value of our Level 3 assets and liabilities. Use of these techniques requires determination of relevant inputs and assumptions, some of which represent significant unobservable inputs as indicated in the preceding table. Accordingly, a significant increase or decrease in any of these inputs – such as anticipated credit losses, prepayment rates, interest rates, or other valuation assumptions – in isolation would likely result in a significantly lower or higher fair value measurement.
Residential loans at Redwood
Estimated fair values for residential loans are determined using models that incorporate various observable inputs, including pricing information from whole loan sales and securitizations. Certain significant inputs in these models are considered unobservable and are therefore Level 3 in nature. Pricing inputs obtained from market whole loan transaction activity include indicative spreads to indexed to be announced ("TBA") prices and indexed swap rates for fixed-rate loans and indexed swap rates for hybrid loans (Level 3). Pricing inputs obtained from market securitization activity include indicative spreads to indexed TBA prices for senior residential mortgage-backed securities ("RMBS") and indexed swap rates for subordinate RMBS, and credit support levels (Level 3). Other unobservable inputs also include assumed future prepayment rates. Observable inputs include benchmark interest rates, swap rates, and TBA prices. At September 30, 2017, our jumbo fixed-rate loans that were not committed to sell were priced using whole loan sale inputs. These assets would generally decrease in value based upon an increase in the credit spread, prepayment speed, or credit support assumptions.
Residential loans at Consolidated Sequoia entities
We have elected to account for the consolidated Sequoia securitization entities as collateralized financing entities ("CFEs") in accordance with GAAP. A CFE is a variable interest entity that holds financial assets and issues beneficial interests in those assets, and these beneficial interests have contractual recourse only to the related assets of the CFE. Accounting guidance for CFEs allow companies to elect to measure both the financial assets and financial liabilities of a CFE using the more observable of the fair value of the financial assets or fair value of the financial liabilities. Pursuant to this guidance, we use the fair value of the ABS issued by the Sequoia CFEs (which we determined to be more observable) to determine the fair value of the loans held at these entities, whereby the net assets we consolidate in our financial statements related to these entities represent the estimated fair value of our retained interests in the Sequoia CFEs.
Real estate securities
Real estate securities include residential, commercial, and other asset-backed securities that are generally illiquid in nature and trade infrequently. Significant inputs in the valuation analysis are predominantly Level 3 in nature, due to the lack of readily available market quotes and related inputs. For real estate securities, we utilize both market comparable pricing and discounted cash flow analysis valuation techniques. Relevant market indicators that are factored into the analysis include bid/ask spreads, the amount and timing of credit losses, interest rates, and collateral prepayment rates. Estimated fair values are based on applying the market indicators to generate discounted cash flows (Level 3). These cash flow models use significant unobservable inputs such as a discount rate, prepayment rate, default rate, loss severity and credit support. The estimated fair value of our securities would generally decrease based upon an increase in default rates, serious delinquencies, or a decrease in prepayment rates or credit support.
As part of our securities valuation process, we request and consider indications of value from third-party securities dealers. For purposes of pricing our securities at September 30, 2017, we received dealer price indications on 73% of our securities, representing 81% of our carrying value. In the aggregate, our internal valuations of the securities for which we received dealer price indications were within 1% of the aggregate average dealer valuations. Once we receive the price indications from dealers, they are compared to other relevant market inputs, such as actual or comparable trades, and the results of our discounted cash flow analysis. In circumstances where relevant market inputs cannot be obtained, increased reliance on discounted cash flow analysis and management judgment are required to estimate fair value.

Note 5. Fair Value of Financial Instruments - (continued)
Derivative assets and liabilities
Our derivative instruments include swaps, swaptions, TBAs, financial futures, and loan purchase commitments ("LPCs"). Fair values of derivative instruments are determined using quoted prices from active markets, when available, or from valuation models and are supported by valuations provided by dealers active in derivative markets. Fair values of TBAs and financial futures are generally obtained using quoted prices from active markets (Level 1). Our derivative valuation models for swaps and swaptions require a variety of inputs, including contractual terms, market prices, yield curves, credit curves, measures of volatility, prepayment rates, and correlations of certain inputs. Model inputs can generally be verified and model selection does not involve significant management judgment (Level 2).
LPC fair values for jumbo loans are estimated based on the estimated fair values of the underlying loans (as described in "Residential loans" above) as well as the probability that the mortgage loan will be purchased (the "Pull-through rate") (Level 3).
For other derivatives, valuations are based on various factors such as liquidity, bid/ask spreads, and credit considerations for which we rely on available market inputs. In the absence of such inputs, management’s best estimate is used (Level 3).
MSRs
MSRs include the rights to service jumbo and conforming residential mortgage loans. Significant inputs in the valuation analysis are predominantly Level 3, due to the nature of these instruments and the lack of readily available market quotes. Changes in the fair value of MSRs occur primarily due to the collection/realization of expected cash flows, as well as changes in valuation inputs and assumptions. Estimated fair values are based on applying the inputs to generate the net present value of estimated future MSR income (Level 3). These discounted cash flow models utilize certain significant unobservable inputs including market discount rates, assumed future prepayment rates of serviced loans, and the market cost of servicing. An increase in these unobservable inputs would generally reduce the estimated fair value of the MSRs.
As part of our MSR valuation process, we received a valuation estimate from a third-party valuations firm. In the aggregate, our internal valuation of the MSRs were within 2% of the third-party valuation.
FHLBC Stock
Our Federal Home Loan Bank ("FHLB") member subsidiary is required to purchase Federal Home Loan Bank of Chicago ("FHLBC") stock under a borrowing agreement between our FHLB-member subsidiary and the FHLBC. Under this agreement, the stock is redeemable at face value, which represents the carrying value and fair value of the stock (Level 2).
Guarantee Asset
The guarantee asset represents the estimated fair value of cash flows we are contractually entitled to receive related to a risk sharing arrangement with Fannie Mae. Significant inputs in the valuation analysis are Level 3, due to the nature of this asset and the lack of market quotes. The fair value of the guarantee asset is determined using a discounted cash flow model, for which significant unobservable inputs include assumed future prepayment rates and market discount rate (Level 3). An increase in prepayment rates or discount rate would generally reduce the estimated fair value of the guarantee asset.
Pledged Collateral
Pledged collateral consists of cash and U.S. Treasury securities held by a custodian in association with certain agreements we have entered into. Treasury securities are carried at their fair value, which is determined using quoted prices in active markets (Level 1).
Cash and cash equivalents
Cash and cash equivalents include cash on hand and highly liquid investments with original maturities of three months or less. Fair values equal carrying values (Level 1).

Note 5. Fair Value of Financial Instruments - (continued)
Restricted cash
Restricted cash primarily includes interest-earning cash balances related to risk sharing transactions with the Agencies, cash held in association with borrowings from the FHLBC, and cash held at consolidated Sequoia entities for the purpose of distribution to investors and reinvestment. Due to the short-term nature of the restrictions, fair values approximate carrying values (Level 1).
Accrued interest receivable and payable
Accrued interest receivable and payable includes interest due on our assets 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 (Level 1).
REO
REO includes properties owned in satisfaction of foreclosed loans. Fair values are determined using available market quotes, appraisals, broker price opinions, comparable properties, or other indications of value (Level 3).
Margin receivable
Margin receivable reflects cash collateral we have posted with our various derivative and debt counterparties as required to satisfy margin requirements. Fair values approximate carrying values (Level 2).
Guarantee Obligations
In association with our risk sharing transactions with the Agencies, we have made certain guarantees. These obligations are initially recorded at fair value and subsequently carried at amortized cost. Fair values of guarantee obligations are determined using internal models that incorporate certain significant inputs that are considered unobservable and are therefore Level 3 in nature. Pricing inputs include assumed future prepayment rates, credit losses, and market discount rates. A decrease in future prepayment rates or discount rates, or an increase in credit losses, would generally cause the fair value of the guarantee obligations to decrease (become a larger liability).
Short-term debt
Short-term debt includes our credit facilities that mature within one year. As these borrowings are secured and subject to margin calls and as the rates on these borrowings reset frequently to market rates, we believe that carrying values approximate fair values (Level 2). Additionally, at September 30, 2017, short-term debt included unsecured convertible senior notes with a maturity of less than one year. The fair value of the convertible notes is determined using quoted prices in generally active markets (Level 2).
ABS issued
ABS issued includes asset-backed securities issued through the Legacy Sequoia and Sequoia Choice securitization entities. These instruments are generally illiquid in nature and trade infrequently. Significant inputs in the valuation analysis are predominantly Level 3, due to the nature of these instruments and the lack of readily available market quotes. For ABS issued, we utilize both market comparable pricing and discounted cash flow analysis valuation techniques. Relevant market indicators factored into the analysis include bid/ask spreads, the amount and timing of collateral credit losses, interest rates, and collateral prepayment rates. Estimated fair values are based on applying the market indicators to generate discounted cash flows (Level 3). A decrease in credit losses or discount rate, or an increase in prepayment rates, would generally cause the fair value of the ABS issued to decrease (become a larger liability).
FHLBC Borrowings
FHLBC borrowings include amounts borrowed from the FHLBC that are secured, generally by residential mortgage loans. As these borrowings are secured and subject to margin calls and as the rates on these borrowings reset frequently to market rates, we believe that carrying values approximate fair values (Level 2).

Our real estate securities include mortgage-backed securities, which are presented in accordance with their general position within a securitization structure based on their rights to cash flows. Senior securities are those interests in a securitization that generally have the first right to cash flows and are last in line to absorb losses. Re-REMIC securities, as presented herein, were created through the resecuritization of certain senior security interests to provide additional credit support to those interests. These re-REMIC securities are therefore subordinate to the remaining senior security interests, but senior to any subordinate tranches of the securitization from which they were created. Subordinate securities are all interests below senior and re-REMIC interests. We further separate our subordinate securities into mezzanine and subordinate, where mezzanine includes securities initially rated AA through BBB- and issued in 2012 or later. Nearly all of our securities are supported by collateral that was designated as prime as of issuance.

At September 30, 2017 and December 31, 2016, all of our available-for-sale securities were comprised of residential mortgage-backed securities. At September 30, 2017, AFS securities with a carrying value of $229 million were pledged as collateral under short-term borrowing agreements. See Note 11 for additional information on short-term debt.
During the three and nine months ended September 30, 2017, we purchased $4 million and $32 million of AFS securities, respectively, and sold $23 million and $61 million of AFS securities, respectively, which resulted in net realized gains of $2 million and $9 million, respectively. During the three and nine months ended September 30, 2016, we purchased $11 million and $29 million of AFS securities, respectively, and sold $26 million and $241 million of AFS securities, respectively, which resulted in net realized gains of $2 million and $20 million, respectively. In addition, during the nine months ended September 30, 2017, we exchanged our interests in three Re-REMICs, which together had a fair value of $47 million, for the senior securities underlying the Re-REMICs, and reclassified our interests from Re-REMIC to Senior.
We often purchase AFS securities at a discount to their outstanding principal balances. To the extent we purchase an AFS security that has a likelihood of incurring a loss, we do not amortize into income the portion of the purchase discount that we do not expect to collect due to the inherent credit risk of the security. We may also expense a portion of our investment in the security to the extent we believe that principal losses will exceed the purchase discount. We designate any amount of unpaid principal balance that we do not expect to receive and thus do not expect to earn or recover as a credit reserve on the security. Any remaining net unamortized discounts or premiums on the security are amortized into income over time using the effective yield method.
At September 30, 2017, there were $0.1 million of AFS securities with contractual maturities less than five years, $0.4 million with contractual maturities greater than five years but less than 10 years, and the remainder of our AFS securities had contractual maturities greater than 10 years.

AFS Securities with Unrealized Losses

At September 30, 2017, after giving effect to purchases, sales, and extinguishment due to credit losses, our consolidated balance sheet included 173 AFS securities, of which 14 were in an unrealized loss position and six were in a continuous unrealized loss position for 12 consecutive months or longer. At December 31, 2016, our consolidated balance sheet included 186 AFS securities, of which 19 were in an unrealized loss position and 10 were in a continuous unrealized loss position for 12 consecutive months or longer.
Evaluating AFS Securities for Other-than-Temporary Impairments
Gross unrealized losses on our AFS securities were $2 million at September 30, 2017. We evaluate all securities in an unrealized loss position to determine if the impairment is temporary or other-than-temporary (resulting in an OTTI). At September 30, 2017, we did not intend to sell any of our AFS securities that were in an unrealized loss position, and it is more likely than not that we will not be required to sell these securities before recovery of their amortized cost basis, which may be at their maturity. We review our AFS securities that are in an unrealized loss position to identify those securities with losses that are other-than-temporary based on an assessment of changes in expected cash flows for such securities, which considers recent security performance and expected future performance of the underlying collateral.
For the nine months ended September 30, 2017, other-than-temporary impairments related to our AFS securities were $0.6 million, of which $0.2 million were recognized through our consolidated statements of income and $0.4 million were recognized in Accumulated other comprehensive income, a component of our consolidated balance sheet. AFS securities for which OTTI is recognized have experienced, or are expected to experience, credit-related adverse cash flow changes. In determining our estimate of cash flows for AFS securities we may consider factors such as structural credit enhancement, past and expected future performance of underlying mortgage loans, including timing of expected future cash flows, which are informed by prepayment rates, default rates, loss severities, delinquency rates, percentage of non-performing loans, FICO scores at loan origination, year of origination, loan-to-value ratios, and geographic concentrations, as well as general market assessments. Changes in our evaluation of these factors impacted the cash flows expected to be collected at the OTTI assessment date and were used to determine if there were credit-related adverse cash flows and if so, the amount of credit related losses. Significant judgment is used in both our analysis of the expected cash flows for our AFS securities and any determination of the credit loss component of OTTI.
The table below summarizes the significant valuation assumptions we used for our AFS securities in unrealized loss positions at September 30, 2017.

Risk Management Derivatives
To manage, to varying degrees, risks associated with certain assets and liabilities on our consolidated balance sheets, we may enter into derivative contracts. At September 30, 2017, we were party to swaps and swaptions with an aggregate notional amount of $2.65 billion, TBA agreements sold with an aggregate notional amount of $1.94 billion, and financial futures contracts with an aggregate notional amount of $37 million. At December 31, 2016, we were party to swaps and swaptions with an aggregate notional amount of $2.46 billion, TBA agreements sold with an aggregate notional amount of $1.36 billion, and financial futures contracts with an aggregate notional amount of $88 million.
During the three and nine months ended September 30, 2017, risk management derivatives had net market valuation losses of $9 million and $36 million, respectively. During the three and nine months ended September 30, 2016, risk management derivatives had net market valuation losses of $5 million and $11 million, respectively. These market valuation gains and losses are recorded in Mortgage banking activities, net, Investment fair value changes, net, and MSR income, net on our consolidated statements of income.

Loan Purchase Commitments
LPCs that qualify as derivatives are recorded at their estimated fair values. Net market valuation gains on LPCs were $13 million and $34 million for the three and nine months ended September 30, 2017, respectively, and were $12 million and $36 million for the three and nine months ended September 30, 2016, respectively. The market valuation gains and losses were recorded in Mortgage banking activities, net on our consolidated statements of income.
Derivatives Designated as Cash Flow Hedges
To manage the variability in interest expense related to portions of our long-term debt and certain adjustable-rate securitization entity liabilities that are included in our consolidated balance sheets for financial reporting purposes, we designated certain interest rate swaps as cash flow hedges with an aggregate notional balance of $140 million.
For the three and nine months ended September 30, 2017, changes in the values of designated cash flow hedges were positive $0.3 million and negative $0.4 million, respectively, and were recorded in Accumulated other comprehensive income, a component of equity. For the three and nine months ended September 30, 2016, changes in the values of designated cash flow hedges were positive $1 million and negative $23 million, respectively, and were recorded in Accumulated other comprehensive income, a component of equity. For interest rate agreements currently or previously designated as cash flow hedges, our total unrealized loss reported in Accumulated other comprehensive income was $44 million at both September 30, 2017 and December 31, 2016.
The following table illustrates the impact on interest expense of our interest rate agreements accounted for as cash flow hedges for the three and nine months ended September 30, 2017 and 2016.

Derivative Counterparty Credit Risk
As discussed in our Annual Report on Form 10-K for the year ended December 31, 2016, we consider counterparty risk as part of our fair value assessments of all derivative financial instruments at each quarter-end. At September 30, 2017, we assessed this risk as remote and did not record a specific valuation adjustment.
At September 30, 2017, we had outstanding derivative agreements with three counterparties (other than clearinghouses) and were in compliance with ISDA agreements governing our open derivative positions.

Note 12. Asset-Backed Securities Issued
Through our Sequoia securitization program, we sponsor securitization transactions in which ABS backed by residential mortgage loans are issued by Sequoia entities. We consolidated the Legacy Sequoia securitization entities, and beginning in September 2017, the Sequoia Choice securitization entity, that we determined were VIEs and for which we determined we were the primary beneficiary. Each consolidated 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. Our exposure to these entities is primarily through the financial interests we have retained, although we are exposed to certain financial risks associated with our role as a sponsor, servicing administrator, or depositor of these entities or as a result of our having sold assets directly or indirectly to these entities.
The ABS issued by these entities consist of various classes of securities that pay interest on a monthly or quarterly basis. All ABS issued by the Sequoia Choice entity pay fixed rates of interest and substantially all ABS issued by the Legacy Sequoia entities pay variable rates of interest, which are indexed to one-, three-, or six-month LIBOR. Some ABS issued by the Legacy Sequoia entities pay hybrid rates, which are fixed rates that subsequently adjust to variable rates. ABS issued also includes some interest-only classes with coupons set at a fixed spread to a benchmark rate, or set at a spread to the interest rates earned on the assets less the interest rates paid on the liabilities of a securitization entity.

The actual maturity of each class of ABS issued is primarily determined by the rate of principal prepayments on the assets of the issuing entity. Each series is also subject to redemption prior to the stated maturity according to the terms of the respective governing documents of each ABS issuing entity. As a result, the actual maturity of ABS issued may occur earlier than its stated maturity. At September 30, 2017, all of the ABS issued and outstanding had contractual maturities beyond five years.
At both September 30, 2017 and December 31, 2016, accrued interest payable on ABS issued by the Legacy Sequoia entities was $1 million. At September 30, 2017, accrued interest payable on ABS issued by the Sequoia Choice entity was $1 million. Interest due on consolidated ABS issued is payable monthly.

During the three and nine months ended September 30, 2017, our FHLB-member subsidiary made no additional borrowings under this agreement. Under a final rule published by the Federal Housing Finance Agency in January 2016, our FHLB-member subsidiary will remain an FHLB member through the five-year transition period for captive insurance companies. Our FHLB-member subsidiary's existing $2.00 billion of FHLB debt, which matures beyond this transition period, is permitted to remain outstanding until its stated maturity. As residential loans pledged as collateral for this debt pay down, we are permitted to pledge additional loans or other eligible assets to collateralize this debt; however, we do not expect to be able to increase our subsidiary's FHLB debt above the existing $2.00 billion maximum.
At September 30, 2017, $2.00 billion of advances were outstanding under this agreement, which were classified as long-term debt, with a weighted average interest rate of 1.3% and a weighted average maturity of approximately eight years. At December 31, 2016, $2.00 billion of advances were outstanding under this agreement, which were classified as long-term debt, with a weighted average interest rate of 0.64% and a weighted average maturity of nine years. Advances under this agreement incur interest charges based on a specified margin over the FHLBC’s 13-week discount note rate, which resets every 13 weeks. Total advances under this agreement were secured by residential mortgage loans with a fair value of $2.26 billion at September 30, 2017. In addition, cash of $24 million served as collateral for these borrowings at September 30, 2017, and is presented as restricted cash on our consolidated balance sheet. This agreement also requires our subsidiary to purchase and hold stock in the FHLBC in an amount equal to a specified percentage of outstanding advances. At September 30, 2017, our subsidiary held $43 million of FHLBC stock that is included in Other assets in our consolidated balance sheets.

Trust Preferred Securities and Subordinated Notes
At September 30, 2017, we had trust preferred securities and subordinated notes outstanding of $100 million and $40 million, respectively.

The $100 million trust preferred securities will be redeemed no later than January 30, 2037, and the $40 million subordinated notes will be redeemed no later than July 30, 2037. Prior to 2014, we entered into interest rate swaps with aggregate notional values totaling $140 million to hedge the variability in this long-term debt interest expense. Including hedging costs and amortization of deferred securities issuance costs, the weighted average interest expense yield on our trust preferred securities and subordinated notes is approximately 6.8% per annum.

Note 14. Commitments and Contingencies - (continued)
Loss Contingencies — Risk Sharing
At September 30, 2017, we had sold conforming loans to the Agencies with an original unpaid principal balance of $3.19 billion, subject to our risk sharing arrangements with the Agencies. At September 30, 2017, the maximum potential amount of future payments we could be required to make under these arrangements was $44 million and this amount was fully collateralized by assets we transferred to pledged accounts and is presented as pledged collateral in Other assets on our consolidated balance sheets. We have no recourse to any third parties that would allow us to recover any amounts related to our obligations under the arrangements. At September 30, 2017, we had not incurred any losses under these arrangements. For the three and nine months ended September 30, 2017, other income related to these arrangements was $1 million and $2 million, respectively. For the three and nine months ended September 30, 2016, other income related to these arrangements was $1 million and $3 million, respectively. For the three and nine months ended September 30, 2017, net market valuation losses related to these investments were $0.3 million and $1 million, respectively. For the three and nine months ended September 30, 2016, net market valuation losses related to these investments were zero and $1 million, respectively.
All of the loans in the reference pools subject to these risk sharing arrangements were originated in 2014 and 2015, and at September 30, 2017, the loans had an unpaid principal balance of $2.19 billion and a weighted average FICO score of 758 (at origination) and LTV of 77% (at origination). At September 30, 2017, $3 million of the loans were 90 days or more delinquent, and $1 million were in foreclosure. At September 30, 2017, the carrying value of our guarantee obligation was $20 million and included $10 million designated as a non-amortizing credit reserve, which we believe is sufficient to cover current expected losses under these obligations.
Our consolidated balance sheets include assets of 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 for which the creditors of these SPEs (the Agencies) do not have recourse to Redwood Trust, Inc. or its affiliates. At September 30, 2017 and December 31, 2016, assets of such SPEs totaled $47 million and $49 million, respectively, and liabilities of such SPEs totaled $20 million and $22 million, respectively.
Loss Contingencies — Residential Repurchase Reserve
We maintain a repurchase reserve for potential obligations arising from representation and warranty violations related to residential loans we have sold to securitization trusts or third parties and for conforming residential loans associated with MSRs that we have purchased from third parties. We do not originate residential loans and we 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. However, in some cases, for example, where loans were acquired from companies that have since become insolvent, repurchase claims may result in our being liable for a repurchase obligation.
At both September 30, 2017 and December 31, 2016, our repurchase reserve associated with our residential loans and MSRs was $5 million and was recorded in Accrued expenses and other liabilities on our consolidated balance sheets. We received 13 repurchase requests during the nine months ended September 30, 2017, and repurchased one loan during this period. During the nine months ended September 30, 2017 and 2016, we recorded $0.5 million of reversal of provision for repurchases and $0.3 million of provision for repurchases, respectively, that were recorded in Mortgage banking activities, net and MSR income, net on our consolidated statements of income.

Loss Contingencies — Litigation
On or about December 23, 2009, the Federal Home Loan Bank of Seattle (the “FHLB-Seattle”) filed a complaint in the Superior Court for the State of Washington (case number 09-2-46348-4 SEA) against Redwood Trust, Inc., our subsidiary, Sequoia Residential Funding, Inc. (“SRF”), Morgan Stanley & Co., and Morgan Stanley Capital I, Inc. (collectively, the “FHLB-Seattle Defendants”) alleging that the FHLB-Seattle Defendants made false or misleading statements in offering materials for a mortgage pass-through certificate (the “Seattle Certificate”) issued in the Sequoia Mortgage Trust 2005-4 securitization transaction (the “2005-4 RMBS”) and purchased by the FHLB-Seattle. Specifically, the complaint alleged that the alleged misstatements concerned the (1) loan-to-value ratio of mortgage loans and the appraisals of the properties that secured loans supporting the 2005-4 RMBS, (2) occupancy status of the properties, (3) standards used to underwrite the loans, and (4) ratings assigned to the Seattle Certificate. The FHLB-Seattle alleges claims under the Securities Act of Washington (Section 21.20.005, et seq.) and sought to rescind the purchase of the Seattle Certificate and to collect interest on the original purchase price at the statutory interest rate of 8% per annum from the date of original purchase (net of interest received) as well as attorneys’ fees and costs. The Seattle Certificate was issued with an original principal amount of approximately $133 million, and, at September 30, 2017, the FHLB-Seattle has received approximately $125 million of principal and $11 million of interest payments in respect of the Seattle Certificate. The matter was subsequently resolved and the claims were dismissed by the FHLB Seattle as to all the FHLB Seattle Defendants. At the time the Seattle Certificate was issued, Redwood agreed to indemnify the underwriters of the 2005-4 RMBS, which underwriters were named as defendants in the action, for certain losses and expenses they might incur as a result of claims made against them relating to this RMBS, including, without limitation, certain legal expenses. Regardless of the resolution of this litigation, we could incur a loss as a result of these indemnities.
On or about July 15, 2010, The Charles Schwab Corporation (“Schwab”) filed a complaint in the Superior Court for the State of California in San Francisco (case number CGC-10-501610) against SRF and 26 other defendants (collectively, the “Schwab Defendants”) alleging that the Schwab Defendants made false or misleading statements in offering materials for various residential mortgage-backed securities sold or issued by the Schwab Defendants. Schwab alleged only a claim for negligent misrepresentation under California state law against SRF and sought unspecified damages and attorneys’ fees and costs from SRF. Schwab claimed that SRF made false or misleading statements in offering materials for a mortgage pass-through certificate (the “Schwab Certificate”) issued in the 2005-4 RMBS and purchased by Schwab. Specifically, the complaint alleged that the misstatements for the 2005-4 RMBS concerned the (1) loan-to-value ratio of mortgage loans and the appraisals of the properties that secured loans supporting the 2005-4 RMBS, (2) occupancy status of the properties, (3) standards used to underwrite the loans, and (4) ratings assigned to the Schwab Certificate. The Schwab Certificate was issued with an original principal amount of approximately $15 million, and, at September 30, 2017, approximately $14 million of principal and $1 million of interest payments have been made in respect of the Schwab Certificate. On November 14, 2014, Schwab voluntarily dismissed with prejudice its negligent misrepresentation claim, which resulted in the dismissal with prejudice of SRF from the action. Subsequently, the matter was resolved and Schwab dismissed its claims against the lead underwriter of the 2005-4 RMBS. At the time the Schwab Certificate was issued, Redwood agreed to indemnify the underwriters of the 2005-4 RMBS, which underwriters were also named as defendants in the action, for certain losses and expenses they might incur as a result of claims made against them relating to this RMBS, including, without limitation, certain legal expenses. Regardless of the resolution of this litigation, Redwood could incur a loss as a result of these indemnities.
Through certain of our wholly-owned subsidiaries, we have in the past engaged in, and expect to continue to engage in, activities relating to the acquisition and securitization of residential mortgage loans. In addition, certain of our wholly-owned subsidiaries have in the past engaged in activities relating to the acquisition and securitization of debt obligations and other assets through the issuance of collateralized debt obligations (commonly referred to as CDO transactions). Because of this involvement in the securitization and CDO businesses, we could become the subject of litigation relating to these businesses, including additional litigation of the type described above, and we could also become the subject of governmental investigations, enforcement actions, or lawsuits, and governmental authorities could allege that we violated applicable law or regulation in the conduct of our business. As an example, in July 2016 we became aware of a complaint filed by the State of California on April 1, 2016 against Morgan Stanley & Co. and certain of its affiliates alleging, among other things, that there were misleading statements contained in offering materials for 28 different mortgage pass-through certificates purchased by various California investors, including various California public pension systems, from Morgan Stanley and alleging that Morgan Stanley made false or fraudulent claims in connection with the sale of those certificates. Of the 28 mortgage pass-through certificates that are the subject of the complaint, two are Sequoia mortgage pass-through certificates issued in 2004 and two are Sequoia mortgage pass-through certificates issued in 2007. With respect to each of those certificates our wholly-owned subsidiary, RWT Holdings, Inc., was the sponsor and our wholly-owned subsidiary, Sequoia Residential Funding, Inc., was the depositor. At the time these

four Sequoia mortgage pass-through certificates were issued, Sequoia Residential Funding, Inc. and Redwood Trust agreed to indemnify the underwriters of these certificates for certain losses and expenses they might incur as a result of claims made against them relating to these certificates, including, without limitation, certain legal expenses. Regardless of the outcome of this litigation, we could incur a loss as a result of these indemnities.
In accordance with GAAP, we review the need for any loss contingency reserves and establish reserves when, in the opinion of management, it is probable that a matter would result in a liability and the amount of loss, if any, can be reasonably estimated. Additionally, we record receivables for insurance recoveries relating to litigation-related losses and expenses if and when such amounts are covered by insurance and recovery of such losses or expenses are due. At September 30, 2017, the aggregate amount of loss contingency reserves established in respect of the FHLB-Seattle and Schwab litigation matters described above was $2 million. We review our litigation matters each quarter to assess these loss contingency reserves and make adjustments in these reserves, upwards or downwards, as appropriate, in accordance with GAAP based on our review.
In the ordinary course of any litigation matter, including certain of the above-referenced matters, we have engaged and may continue to engage in formal or informal settlement communications with the plaintiffs or co-defendants. Settlement communications we have engaged in relating to certain of the above-referenced litigation matters are one of the factors that have resulted in our determination to establish the loss contingency reserves described above. We cannot be certain that any of these matters will be resolved through a settlement prior to trial and we cannot be certain that the resolution of these matters, whether through trial or settlement, will not have a material adverse effect on our financial condition or results of operations in any future period.
Future developments (including resolution of substantive pre-trial motions relating to these matters, receipt of additional information and documents relating to these matters (such as through pre-trial discovery), new or additional settlement communications with plaintiffs relating to these matters, or resolutions of similar claims against other defendants in these matters) could result in our concluding in the future to establish additional loss contingency reserves or to disclose an estimate of reasonably possible losses in excess of our established reserves with respect to these matters. Our actual losses with respect to the above-referenced litigation matters may be materially higher than the aggregate amount of loss contingency reserves we have established in respect of these litigation matters, including in the event that any of these matters proceeds to trial and the plaintiff prevails. Other factors that could result in our concluding to establish additional loss contingency reserves or estimate additional reasonably possible losses, or could result in our actual losses with respect to the above-referenced litigation matters being materially higher than the aggregate amount of loss contingency reserves we have established in respect of these litigation matters include that: there are significant factual and legal issues to be resolved; information obtained or rulings made during the lawsuits could affect the methodology for calculation of the available remedies; and we may have additional obligations pursuant to indemnity agreements, representations and warranties, and other contractual provisions with other parties relating to these litigation matters that could increase our potential losses.

We included participating securities, which are certain equity awards that have non-forfeitable dividend participation rights, in the calculations of basic and diluted earnings per common share as we determined that the two-class method was more dilutive than the alternative treasury stock method for these shares. Dividends and undistributed earnings allocated to participating securities under the basic and diluted earnings per share calculations require specific shares to be included that may differ in certain circumstances.
During the three and nine months ended September 30, 2017 and 2016, certain of our convertible notes were determined to be dilutive and were included in the calculation of diluted EPS under the "if-converted" method. Under this method, the periodic interest expense (net of applicable taxes) for dilutive notes is added back to the numerator and the weighted average number of shares that the notes are entitled to (if converted, regardless of whether they are in or out of the money) are included in the denominator.
For the three and nine months ended September 30, 2017, the number of outstanding equity awards that were antidilutive totaled 6,149 and 5,843, respectively. For the three and nine months ended September 30, 2016, the number of outstanding equity awards that were antidilutive totaled 6,623 and 6,565, respectively.

Note 20. Taxes
For the nine months ended September 30, 2017 and 2016, we recognized a provision for income taxes of $17 million and $1 million, respectively. The following is a reconciliation of the statutory federal and state tax rates to our effective tax rate at September 30, 2017 and 2016.
Table 20.1 – Reconciliation of Statutory Tax Rate to Effective Tax Rate

|  | September 30, 2017 |  | September 30, 2016

We assessed our tax positions for all open tax years (i.e., Federal, 2014 to 2017, and State, 2013 to 2017) at September 30, 2017 and December 31, 2016, and concluded that we had no uncertain tax positions that resulted in material unrecognized tax benefits.
Note 21. Segment Information
During the first quarter of 2017, we reorganized our segments to align with changes in how we view our segments for making operating decisions and assessing performance. Specifically, we eliminated our Commercial segment and renamed our Residential Investments segment as the Investment Portfolio segment. This Investment Portfolio segment now includes both residential investments and our commercial investments, which are primarily comprised of investments in multifamily securities. Our Commercial segment previously included our commercial mortgage banking operations and our commercial loan investments, which were wound-down and sold, respectively, during 2016. We conformed the presentation of prior periods, whereby commercial loan investments are included in the Investment Portfolio segment and commercial mortgage banking activities are included in Corporate/Other. Following is a full description of our current segments.
Our Investment Portfolio segment primarily consists of investments in residential jumbo loans and real estate securities. Our securities portfolio primarily includes investments in residential mortgage-backed securities ("RMBS") retained from our Sequoia securitizations and RMBS issued by third parties, Agency issued CRT securities, as well as investments in Agency issued multifamily securities. Our residential loan investments are primarily made through a subsidiary of Redwood Trust that is a member of the Federal Home Loan Bank of Chicago ("FHLBC") that utilizes attractive long-term financing from the FHLBC to make long-term investments directly in residential loans. This segment also includes residential loans from our consolidated Sequoia Choice entity. The Investment Portfolio segment’s main sources of revenue are interest income from investment portfolio securities and residential loans held-for-investment. Additionally, this segment may realize gains and losses upon the sale of securities. Funding expenses, hedging expenses, direct operating expenses, and tax provisions associated with these activities are also included in this segment.
Our Residential Mortgage Banking segment primarily consists of operating a mortgage loan conduit that acquires residential loans from third-party originators for subsequent sale, securitization, or transfer to our investment portfolio. We typically acquire prime, jumbo mortgages and the related mortgage servicing rights on a flow basis from our network of loan sellers and distribute those loans through our Sequoia private-label securitization program or to institutions that acquire pools of whole loans. We occasionally supplement our flow purchases with bulk loan acquisitions. This segment also includes various derivative financial instruments that we utilize to manage certain risks associated with residential loans we acquire. Our Residential Mortgage Banking segment’s main source of revenue is income from mortgage banking activities, which includes valuation increases (or gains) on the sale or securitization of loans and valuation changes from hedges used to manage risks associated with these activities. Additionally, this segment may generate interest income on loans held pending securitization or sale. Funding expenses, direct operating expenses, and tax expenses associated with these activities are also included in this segment.

Segment contribution represents the measure of profit that we use to assess the performance of our business segments and make resource allocation and operating decisions. Certain expenses not directly assigned or allocated to one of our two segments, as well as activity from certain consolidated Sequoia entities and commercial mortgage banking activities (in the prior year), are included in the Corporate/Other column as reconciling items to our consolidated financial statements. These unallocated expenses primarily include interest expense associated with certain long-term debt, indirect operating expenses, and other expense.

Our Business
Redwood Trust, Inc., together with its subsidiaries, focuses on investing in mortgages and other real estate-related assets and engaging in mortgage banking activities. We seek to invest in real estate-related assets that have the potential to generate attractive cash flow returns over time and to generate income through our mortgage banking activities. We operate our business in two segments: Investment Portfolio and Residential Mortgage Banking.
Our primary sources of income are net interest income from our investment portfolio and non-interest income from our mortgage banking activities. Net interest income consists of the interest income we earn on investments less the interest expense we incur on borrowed funds and other liabilities. Income from mortgage banking activities consists of the profit we seek to generate through the acquisition of loans and their subsequent sale or securitization.
Redwood Trust, Inc. has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), beginning with its taxable year ended December 31, 1994. We generally refer, collectively, to Redwood Trust, Inc. and those of its subsidiaries that are not subject to subsidiary-level corporate income tax as “the REIT” or “our REIT.” We generally refer to subsidiaries of Redwood Trust, Inc. that are subject to subsidiary-level corporate income tax as “our operating subsidiaries” or “our taxable REIT subsidiaries” or “TRS.” Our mortgage banking activities and investments in MSRs are generally carried out through our taxable REIT subsidiaries, while our portfolio of mortgage- and other real estate-related investments is primarily held at our REIT. We generally intend to retain profits generated and taxed at our taxable REIT subsidiaries, and to distribute as dividends at least 90% of the taxable income we generate at our REIT.
Redwood Trust, Inc. 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.
Our Business Segments
During the first quarter of 2017, we reorganized our segments to align with changes in how we view our segments for making operating decisions and assessing performance. Specifically, we eliminated our Commercial segment and renamed our Residential Investments segment as the Investment Portfolio segment. This Investment Portfolio segment now includes both residential investments and our commercial investments, which are primarily comprised of investments in multifamily securities. Our Commercial segment previously included our commercial mortgage banking operations and our commercial loan investments, which were wound-down and sold, respectively, during 2016. We conformed the presentation of prior periods, whereby commercial loan investments are included in the Investment Portfolio segment and commercial mortgage banking activities are included in Corporate/Other. Following is a full description of our current segments.
Our Investment Portfolio segment primarily consists of investments in residential jumbo loans and real estate securities. Our securities portfolio primarily includes investments in residential mortgage-backed securities ("RMBS") retained from our Sequoia securitizations and RMBS issued by third parties, Agency issued credit risk transfer ("CRT") securities, as well as investments in Agency issued multifamily securities. Our residential loan investments are primarily made through a subsidiary of Redwood Trust that is a member of the Federal Home Loan Bank of Chicago ("FHLBC") that utilizes attractive long-term financing from the FHLBC to make long-term investments directly in residential loans. The Investment Portfolio segment’s main sources of revenue are interest income from investment portfolio securities and residential loans held-for-investment. Additionally, this segment may realize gains and losses upon the sale of securities. Funding expenses, hedging expenses, direct operating expenses, and tax provisions associated with these activities are also included in this segment.
Our Residential Mortgage Banking segment primarily consists of operating a mortgage loan conduit that acquires residential loans from third-party originators for subsequent sale, securitization, or transfer to our investment portfolio. We typically acquire prime, jumbo mortgages and the related mortgage servicing rights on a flow basis from our network of loan sellers and distribute those loans through our Sequoia private-label securitization program or to institutions that acquire pools of whole loans. We occasionally supplement our flow purchases with bulk loan acquisitions. This segment also includes various derivative financial instruments that we utilize to manage certain risks associated with residential loans we acquire. Our Residential Mortgage Banking segment’s main source of revenue is income from mortgage banking activities, which includes valuation increases (or gains) on the sale or securitization of loans and valuation changes from hedges used to manage risks associated with these activities. Additionally, this segment may generate interest income on loans held pending securitization or sale. Funding expenses, direct operating expenses, and tax expenses associated with these activities are also included in this segment.
62

Consolidated Securitization Entities
We sponsor our Sequoia securitization program, which we use for the securitization of residential mortgage loans. We are required under Generally Accepted Accounting Principles in the United States (“GAAP”) to consolidate the assets and liabilities of certain Sequoia securitization entities we have sponsored for financial reporting purposes. However, each of these entities is independent of Redwood and of each other, and the assets and liabilities of these entities are not owned by us or legal obligations of ours, respectively, although we are exposed to certain financial risks associated with our role as the sponsor or depositor of these entities and, to the extent we hold securities issued by, or other investments in, these entities, we are exposed to the performance of these entities and the assets they hold. We refer to certain of these securitization entities issued prior to 2012 as “consolidated Legacy Sequoia entities,” and the securitization entity formed in connection with the securitization of Redwood Choice expanded-prime loans as the "consolidated Sequoia Choice entity." Where applicable, in analyzing our results of operations, we distinguish results from current operations “at Redwood” and from consolidated Legacy Sequoia entities or the consolidated Sequoia Choice entity.
Cautionary Statement

Forward-looking statements involve numerous risks and uncertainties. Our actual results may differ from our beliefs, expectations, estimates, and projections and, consequently, you should not rely on these forward-looking statements as predictions of future events. Forward-looking statements are not historical in nature and can be identified by words such as “anticipate,” “estimate,” “will,” “should,” “expect,” “believe,” “intend,” “seek,” “plan” and similar expressions or their negative forms, or by references to strategy, plans, or intentions. These forward-looking statements are subject to risks and uncertainties, including, among other things, those described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, our Quarterly Report on Form 10-Q for the quarter ended June 30, 2017, and this Quarterly Report on Form 10-Q, in each case under the caption “Risk Factors.” Other risks, uncertainties, and factors that could cause actual results to differ materially from those projected may be described from time to time in reports we file with the SEC, including reports on Forms 10-Q and 8-K. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.
Statements regarding the following subjects, among others, are forward-looking by their nature: (i) statements we make regarding Redwood’s business strategy and strategic focus, including statements relating to our overall market position, strategy and long-term prospects; (ii) statements regarding our long-term debt and upcoming maturity of convertible notes in 2018; (iii) statements regarding our investment portfolio, including the potential impact of changes to the capital requirement under our FHLB borrowing facility; (iv) statements regarding our mortgage banking activities, including expectations relating to residential mortgage banking margins, securitization execution, and our expanded-prime Redwood Choice loan program; (v) statements relating to acquiring residential mortgage loans in the future that we have identified for purchase or plan to purchase, including the amount of such loans that we identified for purchase during the third quarter of 2017 and at September 30, 2017, and expected fallout and the corresponding volume of residential mortgage loans expected to be available for purchase; (vi) statements relating to our estimate of our available capital (including that we estimate our available capital as of September 30, 2017 was approximately $330 million, expectations relating to our upcoming $250 million convertible debt maturity, and that we believe we can source incremental capital on an as-needed basis for redeployment through continued optimization of our investment portfolio); (vii) statements we make regarding our dividend policy, including our intention to pay a regular dividend of $0.28 per share per quarter in 2017; and (viii) statements regarding our expectations and estimates relating to the characterization for income tax purposes of our dividend distributions, our expectations and estimates relating to tax accounting, tax liabilities and tax savings, and GAAP tax provisions, and our estimates of REIT taxable income and TRS taxable income.

OVERVIEW
Business Update
We had a strong third quarter of 2017 operationally and financially, and are well positioned to achieve the operating metrics we set out for the year and build momentum as we head towards 2018. Perhaps most importantly, we completed our executive search process with the hiring of Dash Robinson, who started with us in late September in his capacity as Executive Vice President. We also completed three successful securitization issuances, including our first expanded-prime Redwood Choice ("Choice") transaction, and issued convertible debt at an attractive level. We deployed $119 million of capital in new investments, much of it after asset pricing declines in early September. We timed our capital deployment well, as asset prices subsequently reverted, in most cases finishing the quarter at or above June 30, 2017 levels.
In this update, we review our mortgage banking activities, provide our thoughts on capital and investing, and conclude with our outlook for the balance of 2017.
Residential Mortgage Banking
Our mortgage banking team had a strong third quarter of 2017, with our expanded-prime Choice program continuing to drive outperformance. Our initial Choice securitization, backed by $318 million of loans, was received favorably by the market, and attracted a good number of both new and existing investors. The issuance created $31 million of investments for our portfolio, utilizing approximately $13 million of capital - more than double the investment for our portfolio than is produced through a traditional Sequoia securitization. Given the current pace and expected growth of loan purchases under our Choice program, we expect to issue Choice securitizations on a regular basis.
We also completed our fifth and sixth traditional Sequoia securitizations of the year during the third quarter of 2017, backed by loans totaling $839 million; this was followed closely by another traditional Sequoia securitization in early October. In addition, we sold $212 million of whole loans to portfolio buyers during the third quarter.
As loan and RMBS pricing has improved, our loan purchase volumes have risen and we have become more competitive with bank retail and correspondent mortgage channels. Loan purchase commitments, adjusted for fallout, increased to $1.6 billion in the third quarter of 2017, up from $1.4 billion and $1.1 billion in the second and first quarters of 2017, respectively. We had strong growth during the third quarter with our Choice program, which accounted for approximately 30% of our total third quarter loan purchase commitments, adjusted for fallout, versus approximately 20% in the second quarter of 2017. Overall margins remained at or above our long-term expectations of 75-100 basis points during the third quarter of 2017.
Capital and Investing
We aggressively pursued new investments in September when volatility due to hurricane activity drove asset prices down. The bulk of the quarter’s $119 million of capital deployment occurred during this period, and included $63 million in GSE residential credit risk transfer (CRT) securities, $39 million in Sequoia and third-party RMBS, and $17 million in multifamily securities. Year-to-date through September 30, 2017, we have deployed $393 million of capital towards new investments (including $37 million of debt repurchases).
We also sold $49 million of mostly lower yielding securities in the third quarter of 2017, freeing up $20 million of capital for reinvestment, after the repayment of associated debt. Additionally, we issued $245 million of six-year, 4.75% convertible debt in August.
As of September 30, 2017, we estimate that our available capital was approximately $330 million, versus $180 million at June 30, 2017. Although we continue to evaluate our options with regard to the April 2018 maturity of $250 million of our convertible debt, at current market prices the excess cost to retire this debt prior to maturity is unattractive relative to alternative short-term uses of cash. In addition, we believe we can source incremental capital on an as-needed basis for redeployment through continued optimization of our investment portfolio.
We continue to evaluate the potential impact of hurricane activity in Houston and Florida on our investment portfolio, although it is still very early in the process. The vast majority of our non-Agency loans and securities were not impacted by the storms and, to date, we have not incurred any realized losses related to properties in the affected areas. Although we did see some impact to pricing from the hurricanes, most of our investments had positive net market valuation adjustments as the benefit from overall credit spread tightening exceeded any negative impact from the hurricanes.
65

Outlook
As we progress through the fourth quarter of 2017, our current operating metrics are in line with our expectations. While investment portfolio returns have been bolstered by persistent market value increases, we have also maintained consistent levels of net interest income and refined our portfolio mix by selling lower-yielding investments and realizing gains where appropriate. Mortgage banking margins continue to be robust and we are encouraged by the relative mix of Select and Choice loans in our pipeline.
We remain cognizant of forces outside of our control (both financial and otherwise) and their potential impact on our business. With this backdrop, a fully-seated executive team is an important milestone as we continue to think critically about our business assumptions and look ahead to next year and beyond.
Financial and Operational Overview - Third Quarter of 2017
Highlights

• | Our GAAP earnings were $0.41 per share for the third quarter of 2017, as compared with $0.43 per share for the second quarter of 2017. Higher mortgage banking income and interest income were offset by higher interest costs and less benefit from market value increases on our trading securities portfolio relative to the second quarter of 2017.

• | Our GAAP book value was $15.67 per share at September 30, 2017, as compared with $15.29 per share at June 30, 2017. This increase was primarily driven by our quarterly earnings exceeding our dividend, and higher fair values on our available-for-sale securities.

• | We deployed $119 million of capital in the third quarter of 2017 toward new investments, including $63 million in Agency residential CRT securities, $39 million in Sequoia and third-party RMBS, and $17 million in Agency multifamily securities. Year-to-date through September 30, 2017, we deployed $393 million of capital into new investments (including $37 million of debt repurchases).

• | We sold $49 million of securities during the third quarter of 2017, freeing up $20 million of capital for reinvestment after the repayment of associated debt. Year-to-date through September 30, 2017, we sold $148 million of mostly lower yielding securities and $53 million of conforming MSRs, freeing up $131 million of capital for reinvestment after the repayment of associated debt.

• | We purchased $1.5 billion of residential jumbo loans during the third quarter of 2017, and $3.8 billion year-to-date through September 30, 2017. At September 30, 2017, our pipeline of jumbo residential loans identified for purchase was $1.5 billion.

• | Residential loan sales totaled $1.4 billion during the third quarter of 2017 and included $0.2 billion of whole loan sales to third parties and $1.2 billion of loans that were securitized. Year-to-date through September 30, 2017, residential loan sales totaled $3.5 billion, and included $0.9 billion of whole loan sales to third parties and $2.6 billion of loans that were securitized in seven separate transactions including our first expanded-prime Choice securitization.

• | We issued $245 million of six-year, 4.75% convertible debt during the third quarter of 2017.

Book Value per Share
At September 30, 2017, our book value was $1.21 billion, or $15.67 per share, an increase from $15.29 per share at June 30, 2017 and $14.96 at December 31, 2016. The following table sets forth the changes in our book value per share for the three and nine months ended September 30, 2017.

Our GAAP book value per share increased $0.38 per share to $15.67 per share during the third quarter of 2017. This increase was primarily driven by positive mark-to-market adjustments on our available-for-sale securities and our quarterly earnings exceeding our dividend.
Unrealized gains on our available-for-sale securities increased $0.19 per share during the third quarter of 2017, primarily as a result of a positive $0.27 per share mark-to-market adjustment on our available-for-sale securities due to credit spread tightening during the quarter. This increase was partially offset by $0.05 per share of discount amortization income recognized in earnings from the appreciation in the amortized cost basis of our available-for-sale securities, and $0.03 per share of previously unrealized net gains that were realized as income from the sale of securities.

Capital Allocation Summary
This section provides an overview of our capital position and how it was allocated at the end of the third quarter of 2017. A detailed discussion of our liquidity and capital resources is provided in the Liquidity and Capital Resources section of this MD&A that follows.
We use a combination of equity and corporate debt (which we collectively refer to as “capital”) to fund our business. We also utilize various forms of collateralized short-term and long-term debt to finance certain investments and to warehouse some of our inventory of residential loans held-for-sale. We do not consider this collateralized debt as "capital" and, therefore, it is presented separately from allocated capital in the table below. The following table presents how our capital was allocated between business segments and investment types at September 30, 2017.

Total |  |  |  |  |  | $ | 1,783,301 |  |  | 100 | %

(1) | Residential securities presented above includes our $31 million net economic investment in our consolidated Sequoia Choice securitization. This net investment represents the fair value of the securities we retained from this securitization.

(2) | Includes $223 million of multifamily securities and $20 million of investment grade CMBS.

Our total capital was $1.78 billion at September 30, 2017, and included $1.21 billion of equity capital and $0.57 billion of the total $2.57 billion of long-term debt on our consolidated balance sheet. This portion of debt included $201 million of exchangeable debt due in 2019, $245 million of convertible debt due in 2023, and $140 million of trust-preferred securities due in 2037.
Of our $1.78 billion of total capital at September 30, 2017, $1.61 billion (or 90%) was allocated to our investments with the remaining $170 million (or 10%) allocated to our residential mortgage banking activities.
As of September 30, 2017, we estimate that our available capital was approximately $330 million. Although we continue to evaluate our options with regard to the April 2018 maturity of $250 million of our convertible debt, at current market prices the excess cost to retire this debt prior to maturity is unattractive relative to alternative short-term uses of cash. In addition, we believe we can source incremental capital on an as-needed basis for redeployment through continued optimization of our investment portfolio.

Net Interest Income
The decrease in net interest income during the three- and nine-month periods primarily resulted from the sale of our commercial mezzanine loans during 2016. This decline was partially offset by higher net interest income from our residential investments as a result of capital redeployment during 2016 and the first nine months of 2017.
Provision for Loan Losses
The reversal of provision for loan losses in 2016 was related to our commercial mezzanine loans. Prior to their sale in 2016, the commercial loans were reclassified to held-for-sale status, at which point the allowance for loan losses was reversed and no longer maintained for these loans.
Mortgage Banking Activities, Net
Income from mortgage banking activities, net includes results from our residential jumbo mortgage banking operations and, prior to the second quarter of 2016, results from our residential conforming and commercial mortgage banking operations. The increase in mortgage banking activities during the three- and nine-month periods was predominantly due to higher gross margins from our jumbo residential mortgage banking activities on higher volume.
A more detailed analysis of the changes in this line item is included in Residential Mortgage Banking portion of the “Results of Operations b y Segment” section that follows.
69

MSR Income, Net
MSR income, net is comprised of the net fee income we earn from our MSR investments as well as changes in their market value and the market value of their associated derivatives. MSR income decrease d in 2017 primarily due to lower average balances of MSRs outstanding during 2017, as sales and paydowns outpaced new acquisitions.
Investment Fair Value Changes, Net
Investment fair value changes, net, is primarily comprised of the change in fair values of our residential loans held-for-investment and financed with FHLB borrowings, our investment securities classified as trading, and interest rate hedges associated with each of these investments.
During the three and nine months ended September 30, 2017, the positive investment fair value changes primarily resulted from net increases in the fair value of our trading securities and their associated hedges, which were primarily due to tightening credit spreads on these securities during these periods. For the nine months ended September 30, 2017, the increase was partially offset by net decreases in the fair value of our residential loans held-for-investment and their associated hedges, primarily resulting from principal paydowns and hedging costs.
During the three months ended September 30, 2016, the positive investment fair value changes resulted from increases in the fair value of our investments in both trading securities and loans held-for-investment, which were primarily the result of tightening credit spreads. During the nine months ended September 30, 2016, the negative investment fair value changes primarily resulted from decreases in the fair value of our loans held for investment and their associated hedges. These decreases were primarily the result of hedging costs due to interest rate volatility during the first nine months of the year, as well as decreases in fair value resulting from the write-off of premium from loan repayments.
Additional detail on our investment fair value changes is included in the Investment Portfolio portion of the “Results of Operations by Segment” section that follows.
Other Income
Other income in both the three- and nine-month periods was primarily comprised of income from our residential loan risk sharing arrangements with Fannie Mae and Freddie Mac.
Realized Gains, Net
During the third quarter of 2017, we realized gains of $2 million, primarily from the sale of $23 million of AFS securities. During the third quarter of 2016, we realized gains of $7 million, which included $2 million primarily from the sale of $26 million of AFS securities and $5 million from the sale of $208 million of commercial mezzanine loans.
During the nine months ended September 30, 2017, we realized gains of $9 million, which included $10 million of realized gains primarily from the sale of $61 million of AFS securities, partially offset by $1 million of realized loss from the repurchase of $37 million of convertible debt. During the nine months ended September 30, 2016, we realized gains of $26 million, which included $21 million of realized gains primarily from the sale of $241 million of AFS securities and $5 million of realized gains from the sale of $208 million of commercial mezzanine loans.
Operating Expenses
The decrease in operating expenses during the three- and nine-month periods was primarily due to the restructuring of our residential conforming and commercial mortgage banking operations during the first quarter of 2016, which resulted in a lower run-rate of expenses. Excluding $11 million of restructuring charges recorded during the nine months ended September 30, 2016, operating expenses for that period were $60 million.
Provision for Income Taxes
Our income taxes result almost entirely from activity at our taxable REIT subsidiaries, which primarily includes our mortgage banking activities and MSR investments. For both the three- and nine-month periods, the increase in provision for income taxes resulted primarily from higher income from our mortgage banking activities. For additional detail on income taxes, see the “Taxable Income” section that follows.

Results of Operations by Segment
As discussed in the Introduction section of this MD&A, we changed our reportable segments in the first quarter of 2017 and now report on our business using two distinct segments: Investment Portfolio and Residential Mortgage Banking. Our segments are based on our organizational and management structure, which aligns with how our results are monitored and performance is assessed. For additional information on our segments, refer to Note 21 of our Notes to Consolidated Financial Statements in Part I, Item I of this Quarterly Report on Form 10-Q. The following table presents the segment contribution from our two segments, reconciled to our consolidated net income, for the three and nine months ended September 30, 2017 and 2016.

The following sections provide a detailed discussion of the results of operations at each of our two business segments for the three and nine months ended September 30, 2017 and 2016.
The $2 million decrease in net income from Corporate/Other for the three-month periods was primarily due to a $1 million increase in interest expense from convertible debt issued in the third quarter of 2017, a $1 million decrease in income from consolidated Legacy Sequoia entities (the details of which are discussed in the "Results of Consolidated Legacy Sequoia Entities" section that follows), and $2 million of upfront costs associated with the hiring of a new executive in the third quarter of 2017. The $10 million improvement from Corporate/Other for the nine-month periods was primarily due to the $11 million of costs incurred in association with the restructuring of our residential conforming and commercial mortgage banking operations during the first quarter of 2016. In addition, $3 million of net losses related to our commercial mortgage banking operations were included in Corporate/Other for the first quarter of 2016, prior to those operations being wound down.

Investment Portfolio Segment
Our Investment Portfolio segment is primarily comprised of our portfolio of residential mortgage loans held-for-investment and financed through the FHLBC and our real estate securities portfolio. Additionally, beginning in the third quarter of 2017, this segment includes residential loans held-for-investment at our consolidated Sequoia Choice entity.
For segment reporting purposes, certain of our Sequoia senior trading securities were included in our Residential Mortgage Banking segment. As such, they are excluded from any amounts and tables in this section and may not agree with similarly titled amounts and tables in our consolidated financial statements and footnotes.

Overview
The increase in our total investments in the first nine months of 2017 was primarily attributable to the deployment of $230 million of capital into new residential and multifamily securities investments. Additionally, we consolidated $317 million of residential Sequoia Choice loans from a securitization we completed during the third quarter. At September 30, 2017, our economic investment in the Sequoia Choice entity was $31 million, representing subordinate securities we retained in the securitization. For the nine months ended September 30, 2017, the segment contribution from our Investment Portfolio was comprised of $43 million from residential loans, $73 million from residential securities, $18 million from commercial/multifamily securities, and $4 million from MSRs.
Net Interest Income
Net interest income from our Investment Portfolio primarily includes interest income from our residential loans held-for-investment and our securities, as well as the associated interest expense from short-term debt, FHLBC borrowings, and ABS issued. The following table presents the components of net interest income for our Investment Portfolio segment for the three and nine months ended September 30, 2017 and 2016.

The decrease in net interest income from our Investment Portfolio segment during the three- and nine-month periods was primarily due to the sale of our commercial mezzanine loans during 2016, as well as from higher interest costs on our FHLB borrowings during 2017 and higher interest expense associated with securities that were financed during the second and third quarters of 2017. These decreases were partially offset by higher net interest income from real estate securities, primarily resulting from higher average balances of these investments from the redeployment of capital.
Investment fair value changes, net
Market valuation changes included in Investment fair value changes, net, result from changes in the fair value of investments and their associated hedges, generally due to changes in market interest rates, changes in credit spreads, and reductions in the basis of investments due to changes in principal balances. See Note 18 of our Notes to Consolidated Financial Statements in Part I, Item I of this Quarterly Report on Form 10-Q for additional detail regarding the components of Investment fair value changes, net presented on our consolidated statements of income.

The following table presents the components of investment fair value changes for the Investment Portfolio segment by investment type, inclusive of fair value changes of associated risk management derivatives, for the three and nine months ended September 30, 2017 and 2016.

(1) | Includes changes in fair value of the residential loans held-for-sale and the ABS issued at the entity, which netted together represent the change in value of our retained investment (subordinate securities) at the consolidated VIE.

During the three and nine months ended September 30, 2017, the positive investment fair value changes primarily resulted from net increases in the fair value of our trading securities and their associated hedges, which were primarily due to tightening credit spreads on these securities during these periods. In addition, for the three months ended September 30, 2017, investment fair value changes, net benefited from an increase in the fair value of residential loans, driven by tighter credit spreads on these investments during that period. In both the three and nine months ended September 30, 2017, these increases were partially offset by decreases in the fair value of our residential loans held-for-investment and their associated hedges, primarily resulting from principal paydowns and hedging costs.
During the three months ended September 30, 2016, the positive investment fair value changes resulted from increases in the fair value of our investments in both trading securities and loans held-for-investment, which were primarily the result of tightening credit spreads. During the nine months ended September 30, 2016, the negative investment fair value changes primarily resulted from decreases in the fair value of our loans held for investment and their associated hedges. These decreases were primarily the result of hedging costs due to interest rate volatility during the first nine months of the year, as well as decreases in fair value resulting from the write-off of premium from loan repayments.
The increase in fair values from commercial/multifamily trading securities and their associated derivatives during the three- and nine-month periods primarily resulted from credit spread tightening during each period.

(1) | Primarily reflects changes in prepayment assumptions on our MSRs due to changes in benchmark interest rates.

MSR income before the effect of changes in interest rates and other assumptions declined in both the three- and nine-month periods, primarily due to the sale of our conforming MSRs during the second quarter of 2017. The total net effect of changes in assumptions and rates decreased during the nine-month periods, primarily due to lower hedging expenses on MSRs during the first quarter of 2016.
Realized Gains, net
During the third quarter of 2017, we realized gains of $2 million, primarily from the sale of $23 million of AFS securities. During the third quarter of 2016, we realized gains of $7 million, which included $2 million primarily from the sale of $26 million of AFS securities and $5 million from the sale of $208 million of commercial mezzanine loans.
Direct Operating Expenses and Provision for Income Taxes
The decrease in operating expenses at our Investment Portfolio segment for the three and nine months ended September 30, 2017 was primarily attributable to lower operating costs associated with the management of our servicing portfolio. For the three and nine months ended September 30, 2017, the provision for income taxes at our Investment Portfolio segment resulted from GAAP income earned at our TRS during those periods, primarily from MSR income and income on certain securities we hold at our TRS.

(1) | Represents the net transfers of loans into our Investment Portfolio segment from our Residential Mortgage Banking segment and their reclassification from held-for-sale to held-for-investment.

During the three and nine months ended September 30, 2017, we had net transfers of $20 million and $227 million, respectively, of residential loans from our Residential Mortgage Banking segment to our Investment Portfolio segment. At September 30, 2017, $2.26 billion of loans were held by our FHLB-member subsidiary and were financed with $2.00 billion of borrowings from the FHLBC. In connection with these borrowings, our FHLB-member subsidiary is required to hold $43 million of FHLB stock.
At September 30, 2017, the weighted average maturity of these FHLB borrowings was approximately eight years and they had a weighted average cost of 1.3% per annum. This interest cost resets every 13 weeks and we seek to fix the interest cost of these FHLB borrowings over their weighted average maturity by using a combination of swaps, TBAs and other derivatives.
In October 2017, the FHLB increased the capital requirement on our borrowing facility, which effectively increases the portion of loans we finance with equity relative to what was required previously. This change will result in additional capital being allocated to these investments as well as a lower return on the capital as leverage on this portfolio will be reduced.
Under a final rule published by the Federal Housing Finance Agency in January 2016, our FHLB-member subsidiary will remain an FHLB member through the five-year transition period for captive insurance companies. Our FHLB-member subsidiary's existing $2.00 billion of FHLB debt, which matures beyond this transition period, is permitted to remain outstanding until its stated maturity. As residential loans pledged as collateral for this debt pay down, we are permitted to pledge additional loans or other eligible assets to collateralize this debt; however, we do not expect to be able to increase our subsidiary's FHLB debt above the existing $2.00 billion.
The following table presents the unpaid principal balances for residential real estate loans held-for-investment at fair value by product type at September 30, 2017.

The outstanding loans held-for-investment at Redwood at September 30, 2017 were prime-quality, first lien loans, of which 95% were originated between 2013 and 2017 and 5% were originated in 2012 and prior years. The weighted average FICO score of borrowers backing these loans was 772 (at origination) and the weighted average loan-to-value ("LTV") ratio was 65% (at origination). At September 30, 2017, none of these loans were greater than 90 days delinquent or in foreclosure.

We directly finance our holdings of real estate securities with a combination of capital and collateralized debt in the form of repurchase (or “repo”) financing. The following table presents the fair value of our real estate securities that were financed with repurchase debt at September 30, 2017.

At September 30, 2017, we had short-term debt incurred through repurchase facilities of $550 million, which was secured by $663 million of real estate securities. The remaining $693 million of our securities were financed with capital. Our repo borrowings were made under facilities with eight different counterparties, and the weighted average cost of funds for these facilities during the third quarter of 2017 was approximately 2.48% per annum.
At September 30, 2017, the securities we financed through repurchase facilities had no material credit issues. In addition to the allocated capital listed in the table above that directly supports our repurchase facilities (the "financing haircut”), we continue to hold a designated amount of supplemental risk capital available for potential margin calls or future obligations relating to these facilities.
The majority of the $103 million of senior securities noted in the table above are supported by seasoned residential loans originated prior to 2008. The $337 million of mezzanine securities financed through repurchase facilities at September 30, 2017 carry investment grade credit ratings and are supported by residential loans originated between 2012 and 2017. The loans underlying these securities have experienced minimal delinquencies to date. The $223 million of multifamily securities financed through repurchase facilities at September 30, 2017 carry investment grade credit ratings with 7%-8% of structural credit enhancement.
The following table presents our residential securities at September 30, 2017 and December 31, 2016, categorized by portfolio vintage (the years the securities were issued), and by priority of cash flows (senior, re-REMIC, and subordinate). We have additionally separated securities issued through our Sequoia platform or by third parties, including the Agencies.

During the fourth quarter of 2016 and the first nine months of 2017, several Re-REMIC securities we held were exchanged for the underlying senior securities. Several of these exchanged investments had higher relative yields and, as such, the balance of our investments in Re-REMICs and their associated yields declined and the yields of our senior securities increased during the three and nine months ended September 30, 2017, as compared to the same periods in 2016.

We designate any amount of unpaid principal balance that we do not expect to receive and thus do not expect to earn or recover as a credit reserve on each security. Any remaining net unamortized discounts or premiums on the security are amortized into income over time using the effective yield method.
At September 30, 2017, credit reserves for our AFS securities totaled $47 million, or 7.3% of the principal balance of our AFS securities, as compared to $47 million, or 6.8%, at December 31, 2016. During the nine months ended September 30, 2017, increases resulting from acquisitions and impairments were partially offset by reductions in the credit reserve from realized losses, sales and transfers out of credit reserve to accretable discount. During the three and nine months ended September 30, 2017, realized credit losses on our residential securities totaled $1 million and $3 million, respectively. During the three and nine months ended September 30, 2016, realized credit losses on our residential securities totaled $0.3 million and $3 million, respectively.
Residential Loans Held-for-Investment at Sequoia Choice Portfolio
During the third quarter of 2017, we issued our first securitization primarily comprised of expanded-prime Choice loans. We consolidate this Sequoia Choice securitization entity for financial reporting purposes in accordance with GAAP. This entity is independent of Redwood and the assets and liabilities of this entity are not, respectively, owned by us or legal obligations of ours. We record the assets and liabilities of the consolidated Sequoia Choice entity at fair value, based on the estimated fair value of the debt securities (ABS) issued from the securitizations, in accordance with GAAP provisions for collateralized financing entities. At September 30, 2017, the estimated fair value of our economic investment in the consolidated Sequoia Choice entity was $31 million, and was comprised of retained subordinate securities.

The outstanding loans held-for-investment at our Sequoia Choice entity at September 30, 2017 were prime-quality, first lien, 30-year, fixed-rate loans and were originated in 2014 or later. The gross weighted average coupon of these loans was 4.98%, the weighted average FICO score of borrowers backing these loans was 744 (at origination) and the weighted average original LTV ratio was 75% (at origination). At September 30, 2017, none of these loans were greater than 90 days delinquent or in foreclosure.
Mortgage Servicing Rights Portfolio
Our MSRs are held and managed at our taxable REIT subsidiary and typically are acquired together with loans from originators and then separately recognized under GAAP when the MSR is retained and the associated loan is sold to a third party or transferred to a Sequoia residential securitization sponsored by us that meets the GAAP criteria for sale. In addition, we have also purchased MSRs on a flow basis from third parties that sold the associated loans directly to the Agencies. Although we own the rights to service loans, we contract with sub-servicers to perform these activities. Our receipt of MSR income is not subject to any covenants other than customary performance obligations associated with servicing residential loans. If a sub-servicer we contract with was to fail to perform these obligations, our servicing rights could be terminated and we would evaluate our MSR asset for impairment at that time.
The following table provides the activity for MSRs by portfolio for the three and nine months ended September 30, 2017.

Overview
During the first nine months of 2017, we purchased $3.79 billion of predominately prime residential jumbo loans, sold $874 million of jumbo loans to third parties and securitized $2.59 billion of jumbo loans through our Sequoia platform. In addition, we had net transfers of $227 million of jumbo loans to our Investment Portfolio segment and financed them with borrowings from the FHLBC. Our pipeline of loans identified for purchase at September 30, 2017 included $1.49 billion of jumbo loans.
We utilize a combination of capital and our residential loan warehouse facilities to manage our inventory of residential loans held-for-sale. At September 30, 2017, we had $438 million of warehouse debt outstanding to fund our residential loans held-for-sale. The weighted average cost of the borrowings outstanding under these facilities during the third quarter of 2017 was 2.86% per annum. Our warehouse capacity at September 30, 2017 totaled $1.33 billion across four separate counterparties, which should continue to provide sufficient liquidity to fund our residential mortgage banking operations in the near-term.
Our residential mortgage banking operations created investments that allowed us to deploy $57 million of capital into our investment portfolio during the first nine months of 2017. At September 30, 2017, we had 446 loan sellers, up from 406 at the end of 2016. This included 187 jumbo sellers and 259 sellers from various FHLB districts participating in the FHLB's MPF Direct program.
Net Interest Income
Net interest income from residential mortgage banking is primarily comprised of interest income earned on residential loans from the time we purchase the loans to when we sell or securitize them, offset by interest expense incurred on short-term warehouse debt used in part to finance the loans while we hold them on our consolidated balance sheet.
Net interest income from residential mortgage banking increased for both the three- and nine-month periods, primarily due to lower loan warehouse borrowings used to finance our residential loans held-for-sale for each period in 2017, as compared to 2016.
The amount of net interest income we earn on loans held-for-sale is dependent on many variables, including the amount of loans and the time they are outstanding on our consolidated balance sheet and their interest rates, as well as the amount of leverage we employ through the use of short-term debt to finance the loans and the interest rates on that debt. These factors will impact net interest income in future periods.

Mortgage Banking Activities, Net
Mortgage banking activities, net, includes the changes in market value of both the loans we hold for sale and commitments for loans we intend to purchase (collectively, our loan pipeline), as well as the effect of hedges we utilize to manage risks associated with our loan pipeline. Our loan sale profit margins are measured over the period from when we commit to purchase a loan and subsequently sell or securitize the loan. Accordingly, these profit margins may encompass positive or negative market valuation adjustments on loans, hedging gains or losses associated with our loan pipeline, and any other related transaction expenses, and may be realized over the course of one or more quarters for financial reporting purposes.
The following table presents the components of residential mortgage banking activities, net. Amounts presented include both the changes in market values for loans that were sold and associated derivative positions that were settled during the periods presented, as well as changes in market values of loans, derivatives and hedges outstanding at the end of each period.

(2) | Represents market valuation changes of derivatives that are used to manage risks associated with our accumulation of residential loans.

(3) | Amounts in this line include other fee income from loan acquisitions and the provision for repurchase expense, presented net.

The increase s in mortgage banking activities, net for both the three- and nine-month periods were primarily due to higher loan purchase volume and higher gross margins primarily due to improved securitization execution in 2017 as compared to 2016.
Loan purchase commitments ("LPCs"), adjusted for fallout expectations, were $1.57 billion and $4.07 billion for the three and nine months ended September 30, 2017, respectively. Our gross margins for our jumbo loans, which we define as net interest income plus income from mortgage banking activities, divided by LPCs, benefited from tightening credit spreads for both securitizations and whole loans during the first nine months of 2017 and remained above our long-term expectations.
At both September 30, 2017 and December 31, 2016, we had repurchase reserves of $4 million outstanding related to residential loans sold through this segment. For the nine months ended September 30, 2017 and 2016, we recorded $0.2 million of reversal of provision for repurchases and $0.5 million of provision for repurchases, respectively, that was included in income from mortgage banking activities, net, in this segment. We review our loan repurchase reserves each quarter and adjust them as necessary based on current information available at each reporting date.

Operating Expenses and Taxes
Operating expenses for this segment primarily include costs associated with the underwriting, purchase and sale of jumbo residential loans. Operating expenses were relatively consistent for both the three- and nine-month periods.
All residential mortgage banking activities are performed at our taxable REIT subsidiary and the provision for income taxes is generally correlated to the amount of this segment's contribution before income taxes in relation to the TRS's overall GAAP income and associated tax provision. The increase in provision for income taxes in both the three- and nine-month periods primarily resulted from higher segment contribution before income taxes for both periods in 2017. In addition, during 2016 we reversed our valuation allowance on certain deferred tax assets, which further reduced our tax provision in those periods.
Results of Consolidated Legacy Sequoia Entities
We sponsored Sequoia securitization entities prior to 2012 that are reported on our consolidated balance sheets for financial reporting purposes in accordance with GAAP. Each of these entities is independent of Redwood and of each other and the assets and liabilities of these entities are not, respectively, owned by us or legal obligations of ours. We record the assets and liabilities of the consolidated Legacy Sequoia entities at fair value, based on the estimated fair value of the debt securities (ABS) issued from the securitizations, in accordance with GAAP provisions for collateralized financing entities. At September 30, 2017, the estimated fair value of our investments in the consolidated Legacy Sequoia entities was $19 million.
The following tables present the statements of income for the three and nine months ended September 30, 2017, and the balance sheets of the consolidated Legacy Sequoia entities at September 30, 2017 and December 31, 2016. All amounts in the statements of income and balance sheets presented below are included in our consolidated financial statements.

Net Interest Income at Consolidated Legacy Sequoia Entities
The decreases in net interest income for the three- and nine-month periods were primarily attributable to the continued pay down of loans at the consolidated entities.
Investment Fair Value Changes, net at Consolidated Legacy Sequoia Entities
Investment fair value changes, net at consolidated Legacy Sequoia entities includes the change in fair value of the residential loans held-for-investment, REO, and the ABS issued at the entities, which netted together represent the change in value of our retained investments in the consolidated Legacy Sequoia entities. The negative investment fair value changes in both three- and nine-month periods were primarily related to the reduction in basis of retained IO securities as the loans underlying these securities continued to pay down.

(1) | Our tax results for the three and nine months ended September 30, 2017 are estimates until we file our tax return for 2017.

We currently expect all or nearly all of the dividends we distribute in 2017 will be taxable to shareholders as ordinary income and a smaller portion, if any, will be a return of capital, which is generally non-taxable. Based on federal income tax rules related to capital loss carryforwards, none of our 2017 dividend distributions are expected to be characterized as long-term capital gains for federal income tax purposes.
Tax Provision under GAAP
For the three and nine months ended September 30, 2017, we recorded tax provision s of $5 million and $17 million, respectively, compared to a tax provision of $1 million for both the three and nine months ended September 30, 2016. Our tax provision is primarily derived from the activities at our TRS as we do not book a material tax provision associated with income generated at our REIT. The change in tax provision year-over-year was primarily the result of us benefiting from the reversal of the valuation allowance recorded against our federal net deferred tax assets ("DTAs") in 2016. As the federal valuation allowance was fully released in 2016, our TRS effective tax rate in 2017 is expected to be approximately equal to the federal statutory rate. The income or loss generated at our TRS will not affect the tax characterization of our 2017 dividends.
Realization of our DTAs is dependent on many factors, including generating sufficient taxable income prior to the expiration of NOL carryforwards and generating sufficient capital gains in future periods prior to the expiration of capital loss carryforwards. We determine the extent to which realization of our DTAs is not assured and establish a valuation allowance accordingly. At December 31, 2016, we reported net federal ordinary and capital deferred tax liabilities ("DTLs"), and, as such, had no associated valuation allowance. As a result of GAAP income at our TRS, we forecast that we will report net federal ordinary and capital DTLs at December 31, 2017 and consequently no valuation allowance is expected to be recorded against any federal DTA. Consistent with prior periods, we continued to maintain a valuation allowance against our net state DTAs. Our 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.

Differences between Estimated Total Taxable Income and GAAP Income
Differences between estimated taxable income and GAAP income are largely due to the following: (i) we cannot establish loss reserves for future anticipated events for tax but we can for GAAP, as realized credit losses are expensed when incurred for tax and these losses are anticipated through lower yields on assets or through loss provisions for GAAP; (ii) the timing, and possibly the amount, of some expenses (e.g., certain compensation expenses) are different for tax than for GAAP; (iii) since amortization and impairments differ for tax and GAAP, the tax and GAAP gains and losses on sales may differ, resulting in differences in realized gains on sale; (iv) at the REIT and certain TRS entities, unrealized gains and losses on market valuation adjustments of securities and derivatives are not recognized for tax until the instrument is sold or extinguished; (v) for tax, basis may not be assigned to mortgage servicing rights retained when whole loans are sold resulting in lower tax gain on sale; (vi) for tax, we do not consolidate securitization entities as we do under GAAP; and, (vii) dividend distributions to our REIT from our TRS are included in REIT taxable income, but not GAAP income. As a result of these differences in accounting, our estimated taxable income can vary significantly from our GAAP income during certain reporting periods.
The table below reconciles our estimated total taxable income to our GAAP income for the nine months ended September 30, 2017.

Potential Taxable Income Volatility
We expect period-to-period volatility in our estimated taxable income. A description of the factors that can cause this volatility is described in the Taxable Income portion of the Results of Operations section in the MD&A included in Part II, Item 7, of our Annual Report on Form 10-K.

LIQUIDITY AND CAPITAL RESOURCES
Summary
Our principal sources of cash consist of borrowings under mortgage loan warehouse facilities, securities repurchase agreements, payments of principal and interest we receive from our investment portfolios, and cash generated from our operating activities. Our most significant uses of cash are to purchase mortgage loans for our mortgage banking operations, to fund investments in residential loans, to purchase investment securities, to repay principal and interest on our warehouse facilities, repurchase agreements, and long-term debt, to make dividend payments on our capital stock, and to fund our operations.
Our total capital was $1.78 billion at September 30, 2017, and included $1.21 billion of equity capital and $0.57 billion of the total $2.57 billion of long-term debt on our consolidated balance sheet. This portion of debt included $201 million of exchangeable debt due in 2019, $245 million of convertible debt due in 2023, and $140 million of trust-preferred securities due in 2037.
As of September 30, 2017, we estimate that our available capital was approximately $330 million. Although we continue to evaluate our options with regard to our upcoming $250 million convertible debt maturity, at current market prices the excess cost to retire this debt prior to maturity is unattractive relative to alternative short-term uses of cash. In addition, we believe we can source incremental capital on an as-needed basis for redeployment through continued optimization of our investment portfolio.
In February 2016, our Board of Directors approved an authorization for the repurchase of up to $100 million of our common stock and also authorized the repurchase of outstanding debt securities, including convertible and exchangeable debt. This authorization replaced all previous share repurchase plans and has no expiration date. This repurchase authorization does not obligate us to acquire any specific number of shares or securities. Under this authorization, shares or securities may be repurchased in privately negotiated and/or open market transactions, including under plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. During the nine months ended September 30, 2017, there were no shares acquired under this authorization. At September 30, 2017, approximately $86 million of this current authorization remained available for the repurchases of shares of our common stock. Like other investments we may make, any repurchases of our common stock or debt securities under this authorization would reduce our available capital described above.
While we believe our available capital is sufficient to fund our currently contemplated investment activities, we may raise capital from time-to-time to make long-term investments or for other purposes. To the extent we seek additional capital to fund our operations and investment activities or repay existing debt, our approach to raising capital will continue to be based on what we believe to be in the best long-term interests of shareholders.
We are subject to risks relating to our liquidity and capital resources, including risks relating to incurring debt under residential and commercial loan warehouse facilities, securities repurchase facilities, and other short- and long-term debt facilities and other risks relating to our use of derivatives. A further discussion of these risks is set forth below under the heading “Risks Relating to Debt Incurred under Short-and Long-Term Borrowing Facilities."
Cash Flows and Liquidity for the Nine Months Ended September 30, 2017
Cash flows from our mortgage banking activities and our investments can be volatile from quarter to quarter depending on many factors, including the timing and amount of loan and securities acquisitions and sales and repayments, the profitability of mortgage banking activities, as well as changes in interest rates, prepayments, and credit losses. Therefore, cash flows generated in the current period are not necessarily reflective of the long-term cash flows we will receive from these investments or activities.
92

Cash Flows from Operating Activities
Cash flows from operating activities were negative $629 million during the nine months ended September 30, 2017. This amount includes the net cash utilized during the period from the purchase and sale of residential mortgage loans associated with our mortgage banking activities. Purchases of loans are financed to a large extent with short-term debt, for which changes in cash are included as a component of financing activities. Excluding cash flows from the purchase, sale, and principal payments of loans classified as held-for-sale, cash flows from operating activities were positive $13 million and positive $75 million during the first nine months of 2017 and 2016, respectively. Contributing to the negative cash flows from operating activities during the first nine months of 2017 were $38 million of net cash outflows associated with margin funding requirements for our derivatives and short-term debt, which are presented as Other assets on our consolidated balance sheets.
Cash Flows from Investing Activities
During the nine months ended September 30, 2017, our net cash provided by investing activities was $205 million and primarily resulted from principal payments on loans held-for-investment at Redwood and at our consolidated Sequoia entities, proceeds from sales of MSRs, and principal payments from, and proceeds from net sales of, real estate securities. Although we generally intend to hold our investment securities as long-term investments, we may sell certain of these securities in order to manage our interest rate risk and liquidity needs, to meet other operating objectives, and to adapt to market conditions. We cannot predict the timing and impact of future sales of investment securities, if any.
Because many of our investment securities are financed through repurchase agreements, a significant portion of the proceeds from any sales or principal payments of our investment securities would generally be used to repay balances under these financing sources. Similarly, all or a significant portion of cash flows from principal payments of loans at consolidated Sequoia entities (as detailed in the subsection titled "Residential Loans at Consolidated Sequoia Entities" in the Results of Operations section of this MD&A) would generally be used to repay ABS issued by those entities.
In addition, during the nine months ended September 30, 2017, we had transfers of residential loans with a carrying value of $644 million from held-for-sale to held-for-investment, and we retained MSRs with a carrying value of $7 million from the sale of residential loans. These non-cash transactions were not included in cash flows from investing activities.
Cash Flows from Financing Activities
During the nine months ended September 30, 2017, our net cash provided by financing activities was $468 million. This primarily resulted from the issuance of asset-backed securities from our Sequoia Choice securitization in the third quarter of 2017, the issuance of convertible debt in August 2017, and $159 million of net borrowings of short-term debt, which were partially offset by $146 million of repayments of ABS issued.
In December 2016, our Board of Directors announced its intention to pay a regular dividend of $0.28 per share per quarter in 2017. During the nine months ended September 30, 2017, we paid $66 million of cash dividends on our common stock, representing cumulative dividends of $0.84 per share. Additionally, in November 2017, the Board of Directors declared a regular dividend of $0.28 per share for the fourth quarter of 2017, which is payable on December 28, 2017 to shareholders of record on December 15, 2017.
In accordance with the terms of our outstanding deferred stock units, which are stock-based compensation awards, each time we declare and pay a dividend on our common stock, we are required to make a dividend equivalent payment in that same per share amount on each outstanding deferred stock unit.
Short-Term Debt
In the ordinary course of our business, we use recourse debt through several different types of borrowing facilities and use cash borrowings under these facilities to, among other things, fund the acquisition of residential loans (including those we acquire and originate in anticipation of securitization), finance investments in securities and other investments, and otherwise fund our business and operations.
At September 30, 2017, we had four short-term residential loan warehouse facilities with a total outstanding debt balance of $438 million (secured by residential loans with an aggregate fair value of $493 million) and a total uncommitted borrowing limit of $1.33 billion. In addition, at September 30, 2017, we had an aggregate outstanding short-term debt balance of $550 million under eight securities repurchase facilities, which were secured by securities with a fair market value of $663 million. We also had a secured line of credit with no outstanding debt balance and a total borrowing limit of $10 million (secured by securities with a fair market value of $6 million) at September 30, 2017.
93

During the three months ended June 30, 2017, $288 million principal amount of our convertible notes due in 2018 and $2 million of associated unamortized deferred issuance costs were reclassified from long-term debt to short-term debt, as the maturity of the notes was less than one year as of April 2017. Additionally, during the three months ended June 30, 2017, we repurchased $37 million par value of these notes at a premium and recorded a loss on extinguishment of debt of $1 million in Realized gains, net on our consolidated statements of income. At September 30, 2017, the outstanding principal amount of these notes was $250 million.
At September 30, 2017, we had $1.24 billion of short-term debt outstanding. During the first nine months of 2017, the highest balance of our short-term debt outstanding was $1.60 billion.
Long-Term Debt
FHLBC Borrowings
In July 2014, our FHLB-member subsidiary entered into a borrowing agreement with the Federal Home Loan Bank of Chicago. At September 30, 2017, under this agreement, our subsidiary could incur borrowings up to $2.00 billion, also referred to as “advances,” from the FHLBC secured by eligible collateral, including, but not limited to residential mortgage loans. During the nine months ended September 30, 2017, our FHLB-member subsidiary made no additional borrowings under this agreement. Under a final rule published by the Federal Housing Finance Agency in January 2016, our FHLB-member subsidiary will remain an FHLB member through a five-year transition period for captive insurance companies. Our FHLB-member subsidiary's existing $2.00 billion of FHLB debt, which matures beyond this transition period, is permitted to remain outstanding until stated maturity. As residential loans pledged as collateral for this debt pay down, we are permitted to pledge additional loans or other eligible assets to collateralize this debt; however, we do not expect to be able to increase our subsidiary's FHLB debt above the existing $2.00 billion maximum.
At September 30, 2017, $2.00 billion of advances were outstanding under this agreement, which were classified as long-term debt, with a weighted average interest rate of 1.26% per annum and a weighted average maturity of eight years. At September 30, 2017, accrued interest payable on these borrowings was $4 million. Advances under this agreement are charged interest based on a specified margin over the FHLBC’s 13-week discount note rate, which resets every 13 weeks. Our total advances under this agreement were secured by residential mortgage loans with a fair value of $2.26 billion at September 30, 2017. In addition, cash of $24 million served as collateral for these borrowings at September 30, 2017, and is presented as restricted cash on our consolidated balance sheet. This agreement also requires our subsidiary to purchase and hold stock in the FHLBC in an amount equal to a specified percentage of outstanding advances. At September 30, 2017, our subsidiary held $43 million of FHLBC stock that is included in Other assets on our consolidated balance sheets.
Convertible Notes
In August 2017, we issued $245 million principal amount of 4.75% convertible senior notes due 2023. After deducting the underwriting discount and issuance costs, we received approximately $238 million of net proceeds. Including amortization of deferred securities issuance costs, the weighted average interest expense yield on these convertible notes is approximately 5.3% per annum. At September 30, 2017, the outstanding principal amount of these notes was $245 million. At September 30, 2017, the accrued interest payable balance on this debt was $1 million.
In November 2014, one of our taxable subsidiaries issued $205 million principal amount of 5.625% exchangeable senior notes due 2019. After deducting the underwriting discount and issuance costs, we received approximately $198 million of net proceeds. Including amortization of deferred securities issuance costs, the weighted average interest expense yield on these exchangeable notes is approximately 6.3% per annum. During the nine months ended September 30, 2016, we repurchased $4 million par value of these notes at a discount and recorded a gain on extinguishment of debt of $0.3 million in Realized gains, net on our consolidated statements of income. At September 30, 2017, the outstanding principal amount of these notes was $201 million. At September 30, 2017, the accrued interest payable balance on this debt was $4 million.
In March 2013, we issued $288 million principal amount of 4.625% convertible senior notes due 2018. After deducting the underwriting discount and issuance costs, we received approximately $279 million of net proceeds. Including amortization of deferred securities issuance costs, the weighted average interest expense yield on these convertible notes is approximately 4.8% per annum. During the three months ended June 30, 2017, $288 million principal amount of these convertible notes and $2 million of unamortized deferred issuance costs were reclassified from long-term debt to short-term debt, as the maturity of the notes was less than one year as of April 2017. Additionally, during the three months ended June 30, 2017, we repurchased $37 million par value of these notes at a premium and recorded a loss on extinguishment of debt of $1 million in Realized gains, net on our consolidated statements of income. At September 30, 2017, the outstanding principal amount of these notes was $250 million. At September 30, 2017, the accrued interest payable balance on this debt was $5 million.
94

Trust Preferred Securities and Subordinated Notes
At September 30, 2017, we had trust preferred securities and subordinated notes outstanding of $100 million and $40 million, respectively, issued by us in 2006 and 2007. This debt requires quarterly interest payments at a floating rate equal to three-month LIBOR plus 2.25% and must be redeemed no later than 2037. Prior to 2014, we entered into interest rate swaps with aggregate notional values totaling $140 million to hedge the variability in this long-term debt interest expense. Including hedging costs and amortization of deferred securities issuance costs, the weighted average interest expense yield on our trust preferred securities and subordinated notes is approximately 6.8% per annum. These swaps are accounted for as cash flow hedges with all interest recorded as a component of net interest income and other valuation changes recorded as a component of equity.
Asset-Backed Securities
At September 30, 2017, there were $738 million (principal balance) of loans owned at consolidated Legacy Sequoia securitization entities, which were funded with $730 million (principal balance) of ABS issued at these entities. In addition, at September 30, 2017, there were $308 million (principal balance) of loans owned at the consolidated Sequoia Choice securitization entity, which was funded with $277 million (principal balance) of ABS issued at this entity. The loans and ABS issued from these entities are reported at estimated fair value. See the subsections titled "Residential Loans at Sequoia Choice" and "Results of Consolidated Legacy Sequoia Entities" in the Results of Operations section of this MD&A for additional details on these entities.
Risks Relating to Debt Incurred under Short- and Long-Term Borrowing Facilities
As described above under the heading “Results of Operations,” in the ordinary course of our business, we use debt financing obtained through several different types of borrowing facilities to, among other things, finance the acquisition of residential mortgage loans (including those we acquire in anticipation of sale or securitization), and finance investments in securities and other investments. We may also use short- and long-term borrowings to fund other aspects of our business and operations, including the repurchase of shares of our common stock. Debt incurred under these facilities is generally either the direct obligation of Redwood Trust, Inc., or the direct obligation of subsidiaries of Redwood Trust, Inc. and guaranteed by Redwood Trust, Inc. Risks relating to debt incurred under these facilities are described in Part I, Item 2 of our Annual Report on Form 10-K for the year ended December 31, 2016, under the caption “Risks Relating to Debt Incurred under Short- and Long-Term Borrowing Facilities.”
Our sources of debt financing include short-term secured borrowings under residential loan warehouse facilities, short-term securities repurchase facilities, a $10 million committed line of short-term secured credit from a bank, and secured borrowings by our wholly-owned subsidiary, RWT Financial, LLC, under its borrowing facility with the FHLBC.
Aggregate borrowing limits are stated under certain of these facilities, and certain other facilities have no stated borrowing limit, but each of the facilities (with the exception of the $10 million committed line of short-term secured credit) is uncommitted, which means that any request we make to borrow funds under these uncommitted facilities may be declined for any reason, even if at the time of the borrowing request we have then-outstanding borrowings that are less than the borrowing limits under these facilities. In general, financing under these facilities is obtained by transferring or pledging mortgage loans or securities to the counterparty in exchange for cash proceeds (in an amount less than 100% of the principal amount of the transferred or pledged assets). While transferred or pledged assets are financed under a facility, to the extent the market value of the assets declines, we are generally required to either immediately reacquire the assets or meet a margin requirement to transfer or pledge additional assets or cash in an amount at least equal to the decline in value. Margin call provisions under these facilities are further described in Part I, Item 2 of our Annual Report on Form 10-K for the year ended December 31, 2016 under the caption “Risks Relating to Debt Incurred under Short- and Long-Term Borrowing Facilities - Margin Call Provisions Associated with Short-Term Debt and Other Debt Financing.” Financial covenants included in these facilities are further described Part I, Item 2 of our Annual Report on Form 10-K for the year ended December 31, 2016 under the caption “Risks Relating to Debt Incurred under Short- and Long-Term Borrowing Facilities - Financial Covenants Associated with Short-Term Debt and Other Debt Financing.” Financial covenants included in these facilities are further described Part I, Item 2 of our Annual Report on Form 10-K for the year ended December 31, 2016 under the caption “Risks Relating to Debt Incurred under Short- and Long-Term Borrowing Facilities - Financial Covenants Associated with Short-Term Debt and Other Debt Financing.”
95

Because these warehouse facilities are uncommitted, at any given time we may not be able to obtain additional financing under them when we need it, exposing us to, among other things, liquidity risks of the types described in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016 under the heading “Risk Factors,” and in Part II, Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2016 under the heading “Market Risks.” In addition, with respect to residential loans that at any given time are already being financed through these warehouse facilities, we are exposed to market, credit, liquidity, and other risks of the types described in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016 under the heading “Risk Factors,” and in Part II, Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2016 under the heading “Market Risks,” if and when those loans or securities become ineligible to be financed, decline in value, or have been financed for the maximum term permitted under the applicable facility. Additionally, our access to financing under the borrowing facility with the FHLBC is subject to the risks described under the heading “Risk Factors - Recently adopted Federal regulations may limit, eliminate, or reduce the attractiveness of our subsidiary’s ability to use borrowings from the Federal Home Loan Bank of Chicago to finance the mortgage loans and securities it holds and acquires, which could negatively impact our business and operating results” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016.
At September 30, 2017, and through the date of this Quarterly Report on Form 10-Q, we were in compliance with the financial covenants associated with our short-term debt and other debt financing facilities. In particular, with respect to: (i) financial covenants that require us to maintain a minimum dollar amount of stockholders’ equity or tangible net worth, at September 30, 2017 our level of stockholders’ equity and tangible net worth resulted in our being in compliance with these covenants by more than $200 million; and (ii) financial covenants that require us to maintain recourse indebtedness below a specified ratio, at September 30, 2017 our level of recourse indebtedness resulted in our being in compliance with these covenants at a level such that we could incur at least $600 million in additional recourse indebtedness.

The amount shown is the principal balance of the ABS issued and not necessarily the value reported in our consolidated financial statements.

(3) | The anticipated interest payments on consolidated ABS issued is calculated based on the contractual maturity of the ABS and therefore assumes no prepayments of the principal outstanding at September 30, 2017.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from those estimates. A discussion of critical accounting policies and the possible effects of changes in estimates on our consolidated financial statements is included in Note 3 — Summary of Significant Accounting Policies included in Part I, Item 1 of this Quarterly Report on Form 10-Q and in Part I, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2016. Management discusses the ongoing development and selection of these critical accounting policies with the audit committee of the board of directors.
We expect quarter-to-quarter GAAP earnings volatility from our business activities. This volatility can occur for a variety of reasons, including the timing and amount of purchases, sales, calls, and repayment of consolidated assets, changes in the fair values of consolidated assets and liabilities, increases or decreases in earnings from mortgage banking activities, and certain non-recurring events. In addition, the amount or timing of our reported earnings may be impacted by technical accounting issues and estimates. Our critical accounting policies and the possible effects of changes in estimates on our consolidated financial statements are included in the "Critical Accounting Policies and Estimates" section of Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2016.
Market Risks
We seek to manage risks inherent in our business — including but not limited to credit risk, interest rate risk, prepayment risk, liquidity risk, and fair value risk — in a prudent manner designed to enhance our earnings and dividends and preserve our capital. In general, we seek to assume risks that can be quantified from historical experience, to actively manage such risks, and to maintain capital levels consistent with these risks. Information concerning the risks we are managing, how these risks are changing over time, and potential GAAP earnings and taxable income volatility we may experience as a result of these risks is discussed in Part II, Item 7A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.
Other Risks
In addition to the market and other risks described above, our business and results of operations are subject to a variety of types of risks and uncertainties, including, among other things, those described under the caption “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2017, and in this Quarterly Report on Form 10-Q.
NEW ACCOUNTING STANDARDS
A discussion of new accounting standards and the possible effects of these standards on our consolidated financial statements is included in Note 3 — Summary of Significant Accounting Policies included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
Information concerning market risk is incorporated herein by reference to Part II, Item 7A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, as supplemented by the information under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Market Risks” within Item 2 above. Other than the developments described thereunder, including changes in the fair values of our assets, there have been no other material changes in our quantitative or qualitative exposure to market risk since December 31, 2016.

Item 4. Controls and Procedures
We have adopted and maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed on our reports under the Securities Exchange Act of 1934, as amended (the Exchange Act), is recorded, processed, summarized, and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms and that the information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
As required by Rule 13a-15(b) of the Exchange Act, we have carried out an evaluation, under the supervision and with the participation of management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the quarter covered by this report. Based on the foregoing, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective at a reasonable assurance level.
There have been no changes in our internal control over financial reporting during the third quarter of 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION
Item 1. Legal Proceedings
On or about December 23, 2009, the Federal Home Loan Bank of Seattle (the “FHLB-Seattle”) filed a complaint in the Superior Court for the State of Washington (case number 09-2-46348-4 SEA) against Redwood Trust, Inc., our subsidiary, Sequoia Residential Funding, Inc. (“SRF”), Morgan Stanley & Co., and Morgan Stanley Capital I, Inc. (collectively, the “FHLB-Seattle Defendants”) alleging that the FHLB-Seattle Defendants made false or misleading statements in offering materials for a mortgage pass-through certificate (the “Seattle Certificate”) issued in the Sequoia Mortgage Trust 2005-4 securitization transaction (the “2005-4 RMBS”) and purchased by the FHLB-Seattle. Specifically, the complaint alleged that the alleged misstatements concerned the (1) loan-to-value ratio of mortgage loans and the appraisals of the properties that secured loans supporting the 2005-4 RMBS, (2) occupancy status of the properties, (3) standards used to underwrite the loans, and (4) ratings assigned to the Seattle Certificate. The FHLB-Seattle alleges claims under the Securities Act of Washington (Section 21.20.005, et seq.) and sought to rescind the purchase of the Seattle Certificate and to collect interest on the original purchase price at the statutory interest rate of 8% per annum from the date of original purchase (net of interest received) as well as attorneys’ fees and costs. The Seattle Certificate was issued with an original principal amount of approximately $133 million, and, at September 30, 2017, the FHLB-Seattle has received approximately $125 million of principal and $11 million of interest payments in respect of the Seattle Certificate. As of September 30, 2017, the Seattle Certificate had a remaining outstanding principal amount of approximately $8 million. The matter was subsequently resolved and the claims were dismissed by the FHLB Seattle as to all the FHLB Seattle Defendants. At the time the Seattle Certificate was issued, Redwood agreed to indemnify the underwriters of the 2005-4 RMBS, which underwriters were named as defendants in the action, for certain losses and expenses they might incur as a result of claims made against them relating to this RMBS, including, without limitation, certain legal expenses. Regardless of the resolution of this litigation, we could incur a loss as a result of these indemnities.
On or about July 15, 2010, The Charles Schwab Corporation (“Schwab”) filed a complaint in the Superior Court for the State of California in San Francisco (case number CGC-10-501610) against SRF and 26 other defendants (collectively, the “Schwab Defendants”) alleging that the Schwab Defendants made false or misleading statements in offering materials for various residential mortgage-backed securities sold or issued by the Schwab Defendants. Schwab alleged only a claim for negligent misrepresentation under California state law against SRF and sought unspecified damages and attorneys’ fees and costs from SRF. Schwab claimed that SRF made false or misleading statements in offering materials for a mortgage pass-through certificate (the “Schwab Certificate”) issued in the 2005-4 RMBS and purchased by Schwab. Specifically, the complaint alleged that the misstatements for the 2005-4 RMBS concerned the (1) loan-to-value ratio of mortgage loans and the appraisals of the properties that secured loans supporting the 2005-4 RMBS, (2) occupancy status of the properties, (3) standards used to underwrite the loans, and (4) ratings assigned to the Schwab Certificate. The Schwab Certificate was issued with an original principal amount of approximately $15 million, and, at September 30, 2017, approximately $14 million of principal and $1 million of interest payments have been made in respect of the Schwab Certificate. As of September 30, 2017, the Schwab Certificate had a remaining outstanding principal amount of approximately $1 million. On November 14, 2014, Schwab voluntarily dismissed with prejudice its negligent misrepresentation claim, which resulted in the dismissal with prejudice of SRF from the action. Subsequently, the matter was resolved and Schwab dismissed its claims against the lead underwriter of the 2005-4 RMBS. At the time the Schwab Certificate was issued, Redwood agreed to indemnify the underwriters of the 2005-4 RMBS, which underwriters were also named as defendants in the action, for certain losses and expenses they might incur as a result of claims made against them relating to this RMBS, including, without limitation, certain legal expenses. Regardless of the resolution of this litigation, Redwood could incur a loss as a result of these indemnities.

Through certain of our wholly-owned subsidiaries, we have in the past engaged in, and expect to continue to engage in, activities relating to the acquisition and securitization of residential mortgage loans. In addition, certain of our wholly-owned subsidiaries have in the past engaged in activities relating to the acquisition and securitization of debt obligations and other assets through the issuance of collateralized debt obligations (commonly referred to as CDO transactions). Because of this involvement in the securitization and CDO businesses, we could become the subject of litigation relating to these businesses, including additional litigation of the type described above, and we could also become the subject of governmental investigations, enforcement actions, or lawsuits, and governmental authorities could allege that we violated applicable law or regulation in the conduct of our business. As an example, in July 2016 we became aware of a complaint filed by the State of California on April 1, 2016 against Morgan Stanley & Co. and certain of its affiliates alleging, among other things, that there were misleading statements contained in offering materials for 28 different mortgage pass-through certificates purchased by various California investors, including various California public pension systems, from Morgan Stanley and alleging that Morgan Stanley made false or fraudulent claims in connection with the sale of those certificates. Of the 28 mortgage pass-through certificates that are the subject of the complaint, two are Sequoia mortgage pass-through certificates issued in 2004 and two are Sequoia mortgage pass-through certificates issued in 2007. With respect to each of those certificates our wholly-owned subsidiary, RWT Holdings, Inc., was the sponsor and our wholly-owned subsidiary, Sequoia Residential Funding, Inc., was the depositor. At the time these four Sequoia mortgage pass-through certificates were issued, Sequoia Residential Funding, Inc. and Redwood Trust agreed to indemnify the underwriters of these certificates for certain losses and expenses they might incur as a result of claims made against them relating to these certificates, including, without limitation, certain legal expenses. Regardless of the outcome of this litigation, we could incur a loss as a result of these indemnities.
In accordance with GAAP, we review the need for any loss contingency reserves and establish reserves when, in the opinion of management, it is probable that a matter would result in a liability and the amount of loss, if any, can be reasonably estimated. Additionally, we record receivables for insurance recoveries relating to litigation-related losses and expenses if and when such amounts are covered by insurance and recovery of such losses or expenses are due. At September 30, 2017, the aggregate amount of loss contingency reserves established in respect of the FHLB-Seattle and Schwab litigation matters described above was $2 million. We review our litigation matters each quarter to assess these loss contingency reserves and make adjustments in these reserves, upwards or downwards, as appropriate, in accordance with GAAP based on our review.
In the ordinary course of any litigation matter, including certain of the above-referenced matters, we have engaged and may continue to engage in formal or informal settlement communications with the plaintiffs or co-defendants. Settlement communications we have engaged in relating to certain of the above-referenced litigation matters are one of the factors that have resulted in our determination to establish the loss contingency reserves described above. We cannot be certain that any of these matters will be resolved through a settlement prior to trial and we cannot be certain that the resolution of these matters, whether through trial or settlement, will not have a material adverse effect on our financial condition or results of operations in any future period.
Future developments (including resolution of substantive pre-trial motions relating to these matters, receipt of additional information and documents relating to these matters (such as through pre-trial discovery), new or additional settlement communications with plaintiffs relating to these matters, or resolutions of similar claims against other defendants in these matters) could result in our concluding in the future to establish additional loss contingency reserves or to disclose an estimate of reasonably possible losses in excess of our established reserves with respect to these matters. Our actual losses with respect to the above-referenced litigation matters may be materially higher than the aggregate amount of loss contingency reserves we have established in respect of these litigation matters, including in the event that any of these matters proceeds to trial and the plaintiff prevails. Other factors that could result in our concluding to establish additional loss contingency reserves or estimate additional reasonably possible losses, or could result in our actual losses with respect to the above-referenced litigation matters being materially higher than the aggregate amount of loss contingency reserves we have established in respect of these litigation matters include that: there are significant factual and legal issues to be resolved; information obtained or rulings made during the lawsuits could affect the methodology for calculation of the available remedies; and we may have additional obligations pursuant to indemnity agreements, representations and warranties, and other contractual provisions with other parties relating to these litigation matters that could increase our potential losses.

Item 1A. Risk Factors
Our risk factors are discussed under Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016 and under Part II, Item 1A of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2017. In addition, the following risk factor reflects recent developments.
Risks Related to the Potential Elimination or Reduction of the Mortgage-Interest Tax Deduction
Proposed federal tax legislation that was released on November 2, 2017 by the Chair of the Ways and Means Committee of the U.S. House of Representatives would limit the personal income tax deduction of mortgage interest on newly originated residential mortgages in several ways. It is unclear whether this proposed tax reform proposal will be enacted into law as proposed, modified, or abandoned. Elimination of, or restrictions on, the mortgage-interest tax deduction could negatively affect the U.S. housing market, the market value of residential mortgage loans and residential mortgage-backed securities, and the volume of future originations of residential mortgage loans, particularly jumbo mortgage loans, all of which could negatively impact our business or financial results.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
During the three months ended September 30, 2017, we did not sell any equity securities that were not registered under the Securities Act of 1933, as amended.
In February 2016, our Board of Directors approved an authorization for the repurchase of up to $100 million of our common stock and also authorized the repurchase of outstanding debt securities, including convertible and exchangeable debt. This authorization replaced all previous share repurchase plans and has no expiration date. This repurchase authorization does not obligate us to acquire any specific number of shares or securities. Under this authorization, shares or securities may be repurchased in privately negotiated and/or open market transactions, including under plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. During the three and nine months ended September 30, 2017, there were no shares acquired under this authorization. At September 30, 2017, approximately $86 million of this current authorization remained available for the repurchase of shares of our common stock.
The following table contains information on the shares of our common stock that we purchased or otherwise acquired during the three months ended September 30, 2017.
