NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2021
(Unaudited)
Note 1. Organization
Redwood Trust, Inc., together with its subsidiaries, is a specialty finance company focused on several distinct areas of housing credit. Our operating platforms occupy a unique position in the housing finance value chain, providing liquidity to growing segments of the U.S. housing market not served by government programs. We deliver customized housing credit investments to a diverse mix of investors, through our best-in-class securitization platforms; whole-loan distribution activities; and our publicly-traded shares. Our consolidated investment portfolio has evolved to incorporate a diverse mix of residential, business purpose and multifamily investments. Our goal is to provide attractive returns to shareholders through a stable and growing stream of earnings and dividends, capital appreciation, and a commitment to technological innovation that facilitates risk-minded scale. We operate our business in three segments: Residential Lending, Business Purpose Lending, and Third-Party Investments.
Our primary sources of income are net interest income from our investments and non-interest income from our mortgage banking activities. Net interest income primarily 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 is generated through the origination and acquisition of loans, and their subsequent sale, securitization, or transfer to our investment portfolios.
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 generally 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 taxable REIT subsidiaries” or “TRS.”
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.
Note 2. Basis of Presentation
The consolidated financial statements presented herein are at September 30, 2021 and December 31, 2020, and for the three and nine months ended September 30, 2021 and 2020. 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, 2020. In the opinion of management, all normal and recurring adjustments to present fairly the financial condition of the Company at September 30, 2021 and results of operations for all periods presented have been made. The results of operations for the three and nine months ended September 30, 2021 should not be construed as indicative of the results to be expected for the full year.

Note 2. Basis of Presentation - (continued)
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 ("Legacy Sequoia"), certain entities formed during and after 2012 in connection with the securitization of Redwood Select prime loans and Redwood Choice expanded-prime loans ("Sequoia"), entities formed in connection with the securitization of CoreVest single-family rental and bridge loans ("CAFL"), and beginning in the third quarter of 2021, an entity ("Point HEI") formed in connection with the securitization of home equity investment contracts ("HEIs"). We also consolidate the assets and liabilities of certain Freddie Mac K-Series and Freddie Mac Seasoned Loans Structured Transaction ("SLST") securitizations in which we have invested. 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 purchased or retained, although for certain entities we are exposed to financial risks associated with our role as a sponsor or co-sponsor, servicing administrator, collateral 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 and Freddie Mac SLST entities are shown under Residential loans held-for-investment at fair value, the underlying loans at the consolidated Freddie Mac K-Series entity are shown under Multifamily loans held-for-investment at fair value, the underlying single-family rental and bridge loans at the consolidated CAFL entities are shown under Business purpose loans held-for-investment at fair value, and the underlying HEIs at the consolidated Point HEI entity are shown under Other investments 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 (loss), we recorded interest income on the loans owned at these entities and interest expense on the ABS issued by these entities as well as fair value changes, other income and expenses associated with these entities' activities. See Note 14 for further discussion on ABS issued.
We also consolidate two partnerships ("Servicing Investment" entities) through which we have invested in servicing-related assets. We maintain an 80% ownership interest in each entity and have determined that we are the primary beneficiary of these partnerships.
See Note 4 for further discussion on principles of consolidation.
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.
Acquisitions
Refer to our Annual Report on Form 10-K for the year ended December 31, 2020 for additional information regarding the acquisitions of 5 Arches, LLC ("5 Arches") and CoreVest American Finance Lender, LLC and certain affiliated entities ("CoreVest"), including purchase price allocations.

Note 2. Basis of Presentation - (continued)
In connection with the acquisitions of 5 Arches and CoreVest in 2019, we identified and recorded finite-lived intangible assets totaling $25 million and $57 million, respectively. The table below presents the amortization period and carrying value of our intangible assets, net of accumulated amortization at September 30, 2021.
Table 2.1 – Intangible Assets – Activity

|  | Intangible Assets at Acquisition |  | Accumulated Amortization at September 30, 2021 |  | Carrying Value at September 30, 2021 |  | Weighted Average Amortization Period (in years)
(Dollars in Thousands) |  |  |  |
Borrower network |  | $ | 45,300 |  |  | $ | (12,672) |  |  | $ | 32,628 |  |  | 7
Broker network |  | 18,100 |  |  | (9,352) |  |  | 8,748 |  |  | 5

Total |  | $ | 81,300 |  |  | $ | (36,054) |  |  | $ | 45,246 |  |  | 6

All of our intangible assets are amortized on a straight-line basis. For both of the nine months ended September 30, 2021 and 2020, we recorded intangible asset amortization expense of $12 million. Estimated future amortization expense is summarized in the table below.
Table 2.2 – Intangible Asset Amortization Expense by Year

(In Thousands) |  |  |  |  |  | September 30, 2021
2021 (3 months) |  |  |  |  |  | $ | 3,685 |
2022 |  |  |  |  |  | 12,800 |
2023 |  |  |  |  |  | 10,091 |
2024 |  |  |  |  |  | 7,073 |
2025 and thereafter |  |  |  |  |  | 11,597 |
Total Future Intangible Asset Amortization |  |  |  |  |  | $ | 45,246 |

On a quarterly basis, we evaluate our finite-lived intangible assets for impairment indicators and additionally evaluate the useful lives of our intangible assets to determine if revisions to the remaining periods of amortization are warranted. We reviewed our finite-lived intangible assets and determined that the estimated lives were appropriate and that there were no indicators of impairment at September 30, 2021.
A liability resulting from the contingent consideration arrangement with 5 Arches was initially recorded in 2019 at its acquisition-date fair value as part of total consideration for the acquisition of 5 Arches. During the first quarter of 2021, we distributed 806,068 shares of Redwood common stock and paid $1 million in cash in full settlement of the remaining deferred consideration associated with this acquisition.

Other Investments
Strategic Investments
We have made and may make additional strategic investments in companies through our RWT Horizons venture investment strategy or at a corporate level. These investments can take the form of equity or debt and often have conversion features. Depending on the terms of the investments, we may account for these investments under the fair value option or as non-marketable equity securities under the equity method of accounting or the measurement alternative (to the extent they do not have a “readily determinable fair value,” or are not traded in a verifiable public market or are restricted for sale in the public market by a restricted stock legend or otherwise).
Investments accounted for under the fair value option are carried at fair value with periodic changes in value recorded through Investment fair value changes on our consolidated statements of income (loss). For non-marketable securities, we utilize the equity method of accounting when we are able to exert significant influence over but do not control the activities of the investee. Under the equity method of accounting, we generally elect to record our share of earnings or losses from equity method investments on a one-quarter lag and we assess our investments for impairment whenever events or changes in circumstances indicate that the carrying amount of our investment might not be recoverable. Income from equity method investments is recorded in Other income, net on our consolidated statements of income (loss). Under the measurement alternative, the carrying value of our investment is measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Adjustments are determined primarily based on a market approach as of the transaction date and are recorded as a component of Other income, net on our consolidated statements of income (loss).
Recent Accounting Pronouncements
Newly Adopted Accounting Standards Updates ("ASUs")
In August 2021, the FASB issued ASU 2021-06, "Presentation of Financial Statements (Topic 205), Financial Services—Depository and Lending (Topic 942), and Financial Services—Investment Companies (Topic 946): Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants (SEC Update)." This new guidance aligns certain SEC paragraphs in the codification with new SEC rules issued in May 2020 related to changes to the disclosure requirements for acquired and disposed businesses. We adopted this guidance upon issuance in the third quarter of 2021, which did not have a material impact on our consolidated financial statements.
In October 2020, the FASB issued ASU 2020-10, "Codification Improvements." This new guidance updates various codification topics by clarifying or improving disclosure requirements. This new guidance is effective for fiscal years ending after December 15, 2020. We adopted this guidance, as required, in the first quarter of 2021, which did not have a material impact on our consolidated financial statements.
In October 2020, the FASB issued ASU 2020-09, "Debt (Topic 470): Amendments to SEC Paragraphs Pursuant to SEC Release No. 33-10762." This new guidance aligns certain SEC paragraphs in the codification with new SEC rules issued in March 2020 related to changes to the disclosure requirements for registered debt securities. This new guidance became effective January 4, 2021. We adopted this guidance, as required, in the first quarter of 2021, which did not have a material impact on our consolidated financial statements.
In October 2020, the FASB issued ASU 2020-08, "Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs." This new guidance clarifies that an entity should reevaluate whether a callable debt security is within the scope of paragraph 310-20-35-33 for each reporting period. This new guidance is effective for fiscal years ending after December 15, 2020. We adopted this guidance, as required, in the first quarter of 2021, which did not have a material impact on our consolidated financial statements.

In January 2020, the FASB issued ASU 2020-01, "Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)." This new guidance clarifies the interaction of the accounting for equity securities, equity method investments, and certain forward contracts and purchased options. This new guidance is effective for fiscal years beginning after December 15, 2020. We adopted this guidance, as required, in the first quarter of 2021, which did not have a material impact on our consolidated financial statements.
In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." This new guidance simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and by clarifying and amending existing guidance. This new guidance is effective for fiscal years beginning after December 15, 2020. We adopted this guidance, as required, in the first quarter of 2021, which did not have a material impact on our consolidated financial statements.
Other Recent Accounting Pronouncements
In August 2020, the FASB issued ASU 2020-06, "Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40)." This new guidance simplifies the accounting for convertible debt by reducing the number of accounting models to separately present certain conversion features in equity. This new guidance is effective for fiscal years beginning after December 31, 2021. Early adoption is permitted. We plan to adopt this new guidance by the required date and do not anticipate that this update will have a material impact on our consolidated financial statements.
In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This new guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848): Scope." This new guidance clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. This new guidance is effective for all entities as of March 12, 2020 through December 31, 2022. We are currently evaluating the impact the adoption of this standard would have on our consolidated financial statements. Through September 30, 2021, we have not elected to apply the optional expedients and exceptions to any of our existing contracts, hedging relationships, or other transactions.
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.

(1)Amounts presented in these columns are limited in total to the net amount of assets or liabilities presented in the prior column ("Net Amounts of Assets (Liabilities) Presented in Consolidated Balance Sheet") 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 and TBAs are components of derivatives instruments on our consolidated balance sheets. Loan warehouse debt, which is secured by certain residential and business purpose loans, and security repurchase agreements are components of Short-term debt and Long-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, 2021, we consolidated Legacy Sequoia, Sequoia, CAFL, Freddie Mac SLST, Freddie Mac K-Series, and Point HEI securitization entities that we determined were VIEs and for which we determined we were the primary beneficiary. 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 for certain securitizations, we are exposed to financial risks associated with our role as a sponsor, servicing administrator, collateral administrator, or depositor of these entities or as a result of our having sold assets directly or indirectly to these entities.
We also consolidate two Servicing Investment entities formed to invest in servicing-related assets that we determined were VIEs and for which we determined we were the primary beneficiary. At September 30, 2021, we held an 80% ownership interest in, and were responsible for the management of, each entity. See Note 10 for a further description of these entities and the investments they hold and Note 12 for additional information on the minority partner’s non-controlling interest. Additionally, we consolidated an entity that was formed to finance servicer advances that we determined was a VIE and for which we, through our control of one of the aforementioned partnerships, were the primary beneficiary. The servicer advance financing consists of non-recourse short-term securitization debt, secured by servicer advances. We consolidate the securitization entity, but the securitization entity is independent of Redwood and the assets and liabilities are not owned by and are not legal obligations of Redwood. See Note 13 for additional information on the servicer advance financing.
During the third quarter of 2021, we consolidated a Point securitization entity formed to invest in Point HEIs that we determined was a VIE and for which we determined we were the primary beneficiary. At September 30, 2021, we owned a portion of the subordinate certificates issued by the entity and had certain decision making rights for the entity. See Note 10 for a further description of this entity and the investments it holds and Note 12 for additional information on non-controlling interests in the entity. We consolidate the Point securitization entity, but the securitization entity is independent of Redwood and the assets and liabilities are not owned by and are not legal obligations of Redwood.

Note 4. Principles of Consolidation - (continued)
For certain of our consolidated VIEs, we have elected to account for the assets and liabilities of these entities as collateralized financing entities ("CFE"). 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 allows 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. The net equity in an entity effectively represents the fair value of the beneficial interests we own in the entity. The following table presents a summary of the assets and liabilities of these VIEs.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2021
(Unaudited)
Note 4. Principles of Consolidation - (continued)
In addition to our consolidated VIEs for which we made the CFE election, we consolidate additional VIEs for which we did not make the CFE election, and elected to account for the ABS issued by these entities at amortized cost. These include our CAFL Bridge securitization, Freddie Mac SLST re-securitization, and Servicing Investment entities.
We consolidate the assets and liabilities of certain Sequoia, CAFL and Point HEI securitization entities, as we did not meet the GAAP sale criteria at the time we transferred financial assets to these entities. Our involvement in consolidated Sequoia, CAFL and Point HEI entities continues in the following ways: (i) we continue to hold subordinate investments in each entity, and for certain entities, more senior investments; (ii) we maintain certain discretionary rights associated with our sponsorship of, or our subordinate investments in, each entity including rights to direct loss mitigation activities; and (iii) we continue to hold a right to call the assets of certain entities (once they have been paid down below a specified threshold) at a price equal to, or in excess of, the current outstanding principal amount of the entity’s asset-backed securities issued. These factors have resulted in our continuing to consolidate the assets and liabilities of these Sequoia, CAFL and Point HEI entities in accordance with GAAP.
We consolidate the assets and liabilities of certain Freddie Mac K-Series and SLST securitization trusts resulting from our investment in subordinate securities issued by these trusts, and in the case of certain CAFL securitizations, resulting from securities acquired through our acquisition of CoreVest. Additionally, we consolidate the assets and liabilities of Servicing Investment entities from our investment in servicer advance investments and excess MSRs. In each case, we maintain certain discretionary rights associated with the ownership of these investments that we determined reflected a controlling financial interest, as we have both the power to direct the activities that most significantly impact the economic performance of the VIEs and the right to receive benefits of and the obligation to absorb losses from the VIEs that could potentially be significant to the VIEs.
During the three months ended September 30, 2021, we did not call any of our consolidated CAFL entities. During the nine months ended September 30, 2021, we called one of our consolidated CAFL entities and repaid the associated ABS issued. In association with this call, we transferred $45 million (unpaid principal balance) of loans from held-for-investment to held-for-sale.
During 2020, we re-securitized subordinate securities we owned in our consolidated Freddie Mac SLST securitization trusts, through the transfer of these financial assets to a re-securitization trust that we sponsored. We retain a subordinate investment in the re-securitization trust and maintain certain discretionary rights associated with the ownership of this investment that we determined reflected a controlling financial interest in the entity, as we have both the power to direct the activities that most significantly impact the performance of the VIE and the right to receive benefits of and the obligation to absorb losses from the VIE that could potentially be significant to the VIE.
Analysis of Unconsolidated VIEs with Continuing Involvement
Since 2012, we have transferred residential loans to 50 Sequoia securitization entities sponsored by us that are still outstanding as of September 30, 2021, 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 certain of these transfers to securitization entities, for the transferred loans where we held the servicing rights prior to the transfer and continued to hold the servicing rights following the transfer, we recorded mortgage servicing rights ("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 servicing rights (which we retain a third-party sub-servicer to perform) and the receipt of interest income associated with the securities we retained.
During the three months ended September 30, 2021, we called two of our unconsolidated Sequoia entities, and purchased $66 million (unpaid principal balance) of loans from the securitization trusts. In association with these calls, we realized a $6 million gain on the securities we owned from these called securitizations, which was recognized through Realized gains, net on our consolidated statements of income (loss). During the nine months ended September 30, 2021, we called six of our unconsolidated Sequoia entities, and purchased $167 million (unpaid principal balance) of loans from the securitization trusts. In association with these calls, we realized a $15 million gain on the securities we owned from these called securitizations, which was recognized through Realized gains, net on our consolidated statements of income (loss). At September 30, 2021, we held $151 million of loans for sale at fair value that were acquired following the calls.

Analysis of Unconsolidated 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 and other investments 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, 2021 and December 31, 2020, grouped by asset type.
Table 4.8 – Third-Party Sponsored VIE Summary

(In Thousands) |  | September 30, 2021 |  | December 31, 2020
Mortgage-Backed Securities |  |  |  |
Senior |  | $ | 4,114 |  |  | $ | 11,131 |
Mezzanine |  | — |  |  | 2,014 |

Total Mortgage-Backed Securities |  | 206,032 |  |  | 186,668 |
Excess MSR |  | 11,368 |  |  | 14,133 |
Total Investments in Third-Party Sponsored VIEs |  | $ | 217,400 |  |  | $ | 200,801 |

We determined that we are not the primary beneficiary of these 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.

(1)The weighted average input values for all loan types are based on the unpaid principal balance. The weighted average input values for all other assets and liabilities are based on relative fair value.
(2)The fair value of the loans and HEIs held by consolidated entities was based on the fair value of the ABS issued by these entities and the securities and other investments we own in those entities, which we determined were more readily observable in accordance with accounting guidance for collateralized financing entities. At September 30, 2021, the fair value of securities we owned at the consolidated Sequoia, CAFL SFR, Freddie Mac SLST, Freddie Mac K-Series, and Point HEI entities was $240 million, $288 million, $451 million, $31 million, and $10 million, respectively.
(3)Represents the estimated average duration of outstanding servicer advances at a given point in time (not taking into account new advances made with respect to the pool).
(4)As a market convention, certain securities are priced to a no-loss yield and therefore do not include default and loss severity assumptions.

Note 5. Fair Value of Financial Instruments - (continued)
Determination of Fair Value
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.
Included in Note 5 to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2020 is a more detailed description of our financial instruments measured at fair value and their significant inputs, as well as the general classification of such instruments pursuant to the Level 1, Level 2, and Level 3 valuation hierarchy.
In addition to the Level 3 financial instruments included in Table 5.7 above, certain of our Other investments (comprised of strategic investments in early-stage start-up companies) are Level 3 financial instruments that we account for under the fair value option. These investments generally take the form of equity or debt with conversion features and do not have readily determinable fair values. We generally value these assets based on our original investment price until there is an observable price change in an orderly transaction for the identical or similar investment of the same issuer.
Note 6. Residential Loans
We acquire residential loans from third-party originators and may sell or securitize these loans or hold them for investment.

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. Mezzanine securities are interests that are generally subordinate to senior securities in their rights to receive cash flows, and have subordinate securities below them that are first to absorb losses. Subordinate securities are all interests below mezzanine. Exclusive of our re-performing loan securities, nearly all of our residential securities are supported by collateral that was designated as prime at the time of issuance.

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, 2021, we had $28 million of AFS securities with contractual maturities less than five years, $4 million with contractual maturities greater than five years but less than ten years, and the remainder of our AFS securities had contractual maturities greater than ten years.

At September 30, 2021, after giving effect to purchases, sales, and extinguishment due to credit losses, our consolidated balance sheet included 84 AFS securities, of which one was in a continuous unrealized loss position for 12 consecutive months or longer. At December 31, 2020, our consolidated balance sheet included 96 AFS securities, of which five were in an unrealized loss position and zero were in a continuous unrealized loss position for 12 consecutive months or longer.
Evaluating AFS Securities for Credit Losses
Gross unrealized losses on our AFS securities were $33 thousand at September 30, 2021. We evaluate all securities in an unrealized loss position to determine if the impairment is credit-related (resulting in an allowance for credit losses recorded in earnings) or non-credit-related (resulting in an unrealized loss through other comprehensive income). At September 30, 2021, 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 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.
At September 30, 2021, our current expected credit loss ("CECL") allowance related to our AFS securities was zero. AFS securities for which an allowance 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 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 security credit losses.
The table below summarizes the weighted average of the significant credit quality indicators we used for the credit loss allowance on our AFS securities at September 30, 2021.

Servicer advance investments
We and a third-party co-investor, through two partnerships (“SA Buyers”) consolidated by us, purchased the outstanding servicer advances and excess MSRs related to a portfolio of legacy residential mortgage-backed securitizations serviced by the co-investor (Refer to our Annual Report on Form 10-K for the year ended December 31, 2020 for additional information regarding the transactions). At September 30, 2021, we had funded $94 million of total capital to the SA Buyers (see Note 16 for additional detail).
At September 30, 2021, our servicer advance investments had a carrying value of $170 million and were associated with a portfolio of residential mortgage loans with an unpaid principal balance of $7.53 billion. The outstanding servicer advance receivables associated with this investment were $159 million at September 30, 2021, which were financed with short-term non-recourse securitization debt (see Note 13 for additional detail on this debt). The servicer advance receivables were comprised of the following types of advances at September 30, 2021 and December 31, 2020.

HEIs
In 2019, we entered into a flow purchase agreement to acquire home equity investment contracts from Point Digital. At September 30, 2021, we had acquired $47 million of HEIs under this flow purchase agreement. We account for these investments under the fair value option and during the three and nine months ended September 30, 2021, we recorded net market valuation gains of $6 million and $13 million, respectively, related to these assets through Investment fair value changes, net on our consolidated statements of income (loss). During the three and nine months ended September 30, 2020, we recorded a net market valuation gain of $2 million and a net market valuation loss of $4 million, respectively, related to these assets through Investment fair value changes, net on our consolidated statements of income (loss).
During the three months ended September 30, 2021, in conjunction with co-sponsoring a securitization of HEIs, we purchased $122 million of additional HEIs from other contributors to the securitization, then transferred $170 million of HEIs to the Point HEI securitization entity and issued $146 million of ABS (See Note 4 for further discussion on the Point securitization entity and Note 14 for further discussion on ABS issued). We retained subordinate certificates from the entity valued at $10 million as of September 30, 2021, representing our economic interest in the entity. The other contributors to the securitization own subordinate certificates in the entity that were valued at $17 million at September 30, 2021 and are carried on our balance sheet as non-controlling interests within the Accrued expenses and other liabilities line item of our consolidated balance sheets.
We consolidate the Point HEI securitization entity in accordance with GAAP and have elected to account for it under the CFE election. During the three months ended September 30, 2021, we recorded net market valuation gains of less than $0.1 million re lated to our net investment in the Point HEI entity through Investment fair value changes, net on our consolidated statements of income (loss).
During three months ended September 30, 2021, we amended our flow purchase agreement with Point Digital and committed to purchase additional HEIs. See Note 16 for additional detail on this commitment.
Strategic Investments
Strategic investments represent investments we have made in companies through our RWT Horizons venture investment strategy or at a corporate level. At September 30, 2021, we had made 11 investments in companies through RWT Horizons and two corporate investments, including our investment in Churchill Finance. See Note 3 for additional detail on how we account for our strategic investments.
Excess MSRs
In association with our servicer advance investments described above, we (through our consolidated SA Buyers) invested in excess MSRs associated with the same portfolio of legacy residential mortgage-backed securitizations. Additionally, we own excess MSRs associated with specified pools of multifamily loans. We account for our excess MSRs at fair value and during the three and nine months ended September 30, 2021, we recognized $3 million and $9 million of interest income, respectively, through Other interest income, and recorded net market valuation losses of $1 million and $5 million, respectively, through Investment fair value changes, net on our consolidated statements of income (loss). During the three and nine months ended September 30, 2020, we recognized $3 million and $9 million of interest income, respectively, through Other interest income, and recorded net market valuation losses of $1 million and $8 million, respectively, through Investment fair value changes, net on our consolidated statements of income (loss).
Mortgage Servicing Rights
We invest in mortgage servicing rights associated with residential mortgage loans and contract with licensed sub-servicers to perform all servicing functions for these loans. The majority of our investments in MSRs were made through the retention of servicing rights associated with the residential jumbo mortgage loans that we acquired and subsequently sold to third parties. During the three and nine months ended September 30, 2021, we retained $5 million and $9 million of MSRs, respectively, from sales of residential loans to third parties. We hold our MSR investments at our taxable REIT subsidiaries.

Derivatives Designated as Cash Flow Hedges
To manage the variability in interest expense related to a portion of our long-term debt that is included in our consolidated balance sheets for financial reporting purposes, we designated certain interest rate swaps as cash flow hedges.
During the first quarter of 2020, we terminated and settled all of our outstanding derivatives that had been designated as cash flow hedges for our long-term debt, with a payment of $84 million. For interest rate agreements previously designated as cash flow hedges, our total unrealized loss reported in Accumulated other comprehensive income was $77 million and $81 million at September 30, 2021 and December 31, 2020, respectively. We are amortizing this loss into interest expense over the remaining term of the debt they were originally hedging. As of September 30, 2021, we expect to amortize $4 million of realized losses related to terminated cash flow hedges into interest expense over the next twelve months.
For both the three and nine months ended September 30, 2021, we did not have any derivatives designated as cash flow hedges. For the three and nine months ended September 30, 2020, changes in the values of designated cash flow hedges were zero and negative $33 million, respectively, and were recorded in Accumulated other comprehensive income, a component of equity.
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, 2021 and 2020.

At September 30, 2021, we assessed this risk as remote and did not record an associated specific valuation adjustment.
At September 30, 2021, we were in compliance with our derivative counterparty ISDA agreements.

For the three and nine months ended September 30, 2021, the average balances of our short-term debt facilities were $1.98 billion and $1.61 billion, respectively. At September 30, 2021 and December 31, 2020, accrued interest payable on our short-term debt facilities was $2 million and $1 million, respectively.
Servicer advance financing consists of non-recourse short-term securitization debt used to finance servicer advance investments. We consolidate the securitization entity that issued the debt, but the entity is independent of Redwood and the assets and liabilities are not owned by and are not legal obligations of Redwood. At September 30, 2021, the accrued interest payable balance on this financing was $0.1 million and the unamortized capitalized commitment costs were $0.1 million.
We also maintain a $10 million committed line of credit with a financial institution that is secured by certain mortgage-backed securities with a fair market value of $2 million at September 30, 2021. At both September 30, 2021 and December 31, 2020, we had no outstanding borrowings on this facility.

(3)Certain ABS issued by CAFL, Freddie Mac SLST, and Point HEI entities is subject to early redemption and interest rate step-ups as described below.
During the third quarter of 2021, we consolidated the assets and liabilities of a securitization entity formed in connection with the securitization of CoreVest bridge loans (presented within CAFL in table 14.1 above), which we determined was a VIE and for which we determined we are the primary beneficiary. At issuance, we sold $270 million (principal balance) of ABS issued to third parties and retained the remaining beneficial ownership interest in the trust. The ABS were issued at a discount and we have elected to account for the ABS issued at amortized cost. At September 30, 2021, the principal balance of the ABS issued was $270 million, and the debt discount and deferred issuance costs were $3 million, for a net carrying value of $267 million. The weighted average stated coupon of the ABS issued was 2.34% at issuance. The ABS issued by the CAFL bridge entity are subject to an optional redemption in March 2024, and beginning in March 2025 the interest rate on the ABS issued increases by 2% through final maturity in March 2029. The ABS issued by this securitization were backed by assets including $276 million of bridge loans and $28 million of restricted cash at September 30, 2021. The securitization is structured with $300 million of total funding capacity and a feature to allow reinvestment of loan payoffs for the first 30 months of the transaction (through March 2024).
During the third quarter of 2021, we consolidated the assets and liabilities of the Point HEI entity formed in connection with the securitization of HEIs, which we determined was a VIE and for which we determined we are the primary beneficiary. At issuance, we sold $146 million (principal balance) of ABS issued to third parties and retained a portion of the remaining beneficial ownership interest in the trust. We elected to account for the entity under the CFE election and account for the ABS issued at fair value, with the entire change in fair value of the ABS issued (including accrued interest) recorded through Investment fair value changes, net on our consolidated statements of income (loss). The ABS issued by the Point HEI entity are subject to an optional redemption in September 2023, and beginning in September 2024 the interest rate on the ABS issued increases by 2% through final maturity in 2052.
During the third quarter of 2020, we transferred all of the subordinate securities we owned from two consolidated re-performing loan securitization VIEs sponsored by Freddie Mac SLST to a re-securitization trust, which we determined was a VIE and for which we determined we are the primary beneficiary. At issuance, we sold $210 million (principal balance) of ABS issued to third parties and retained 100% of the remaining beneficial ownership interest in the trust through ownership of a subordinate security issued by the trust. The ABS was issued at a discount and we have elected to account for the ABS issued at amortized cost. At September 30, 2021, the principal balance of the ABS issued was $163 million, and the debt discount and deferred issuance costs were $3 million, for a carrying value of $161 million. The stated coupon of the ABS issued was 4.75% at issuance and the final stated maturity occurs in July 2059. The ABS issued is subject to an optional redemption in July 2022 and in July 2023 the ABS interest rate steps up to 7.75%.

Note 14. Asset-Backed Securities Issued - (continued)
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, 2021, the majority of the ABS issued and outstanding had contractual maturities beyond five years. See Note 4 for detail on the carrying value components of the collateral for ABS issued and outstanding.

During the nine months ended September 30, 2021, we did not enter into any new office leases. During the nine months ended September 30, 2021, we increased our operating lease right-of-use assets and liabilities by $1 million as the result of an amendment to one of our existing leases. At September 30, 2021, our operating lease liabilities were $16 million, which were a component of Accrued expenses and other liabilities, and our operating lease right-of-use assets were $14 million, which were a component of Other assets.
We determined that none of our leases contained an implicit interest rate and used a discount rate equal to our incremental borrowing rate on a collateralized basis to determine the present value of our total lease payments. As such, we determined the applicable discount rate for each of our leases using a swap rate plus an applicable spread for borrowing arrangements secured by our real estate loans and securities for a length of time equal to the remaining lease term on the date of adoption. At September 30, 2021, the weighted-average remaining lease term and weighted-average discount rate for our leases was 7 years and 4.9%, respectively.
Commitment to Fund Bridge Loans
As of September 30, 2021, we had commitments to fund up to $426 million of additional advances on existing bridge loans. These commitments are generally subject to loan agreements with covenants regarding the financial performance of the borrower and other terms regarding advances that must be met before we fund the commitment. At September 30, 2021, we carried a $1 million contingent liability related to these commitments to fund construction advances. During the three and nine months ended September 30, 2021, we recorded a net market valuation loss of $0.3 million and a net market valuation gain of $1 million, respectively, related to this liability through Mortgage banking activities, net on our consolidated statements of income (loss). During the three and nine months ended September 30, 2020, we recorded a net market valuation gain of $1 million and a net market valuation loss of $1 million, respectively, related to this liability through Mortgage banking activities, net on our consolidated statements of income (loss).
Commitment to Fund Partnerships
In 2018, we invested in two partnerships created to acquire and manage certain mortgage servicing related assets (see Note 10 for additional detail). In connection with this investment, we are required to fund future net servicer advances related to the underlying mortgage loans. The actual amount of net servicer advances we may fund in the future is subject to significant uncertainty and will be based on the credit and prepayment performance of the underlying loans.

Commitment to Acquire HEIs
In the third quarter of 2021, we amended an existing flow purchase agreement with Point Digital to acquire HEIs that Point Digital originates with homeowners. Each HEI provides the owner of such HEI the right to purchase a percentage ownership interest in an associated residential property, and the homeowner's obligations under the HEI are secured by a lien (primarily second liens) on the property created by a deed of trust or a mortgage. Our investments in HEIs allow us to share in both home price appreciation and depreciation of the associated property. At September 30, 2021, we had an outstanding commitment to fund up to $125 million under this agreement.
Loss Contingencies — Risk-Sharing
During 2015 and 2016, we 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, 2021, the maximum potential amount of future payments we could be required to make under these arrangements was $44 million and this amount was partially 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, 2021, we had incurred less than $0.1 million of losses under these arrangements. For the three and nine months ended September 30, 2021, other income related to these arrangements was $1 million and $2 million, respectively, and net market valuation losses related to these investments were less than $0.1 million and $0.1 million, respectively. For the three and nine months ended September 30, 2020, other income related to these arrangements was $1 million and $3 million, respectively, and net market valuation losses related to these investments were $0.3 million 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, 2021, the loans had an unpaid principal balance of $618 million and a weighted average FICO score of 756 (at origination) and LTV ratio of 74% (at origination). At September 30, 2021, $21 million of the loans were 90 days or more delinquent, of which one of these loans with an unpaid principal balance of $0.2 million was in foreclosure. At September 30, 2021, the carrying value of our guarantee obligation was $8 million and included $5 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 us. At September 30, 2021 and December 31, 2020, assets of such SPEs totaled $34 million and $46 million, respectively, and liabilities of such SPEs totaled $8 million and $10 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. Additionally, for certain loans we sold during the second quarter of 2020 that were previously held for investment, we have a direct obligation to repurchase these loans in the event of any early payment defaults (or "EPDs") by the underlying mortgage borrowers within certain specified periods following the sales.
At both September 30, 2021 and December 31, 2020, our repurchase reserve associated with our residential loans and MSRs was $9 million and was recorded in Accrued expenses and other liabilities on our consolidated balance sheets.
During the nine months ended September 30, 2021 and 2020, we received three and eight repurchase requests, respectively, and repurchased one and zero loans, respectively. During the nine months ended September 30, 2021 and 2020, we recorded repurchase provisions of $0.6 million and $4 million, respectively, that were recorded in Mortgage banking activities, net; Investment fair value changes, net; and Other income on our consolidated statements of income (loss).

Loss Contingencies — Litigation, Claims and Demands
There is no significant update regarding the litigation matters described in Note 16 within the financial statements included in Redwood’s Annual Report on Form 10-K for the year ended December 31, 2020 under the heading “Loss Contingencies - Litigation.” At September 30, 2021, the aggregate amount of loss contingency reserves established in respect of the FHLB-Seattle and Schwab litigation matters described in our Annual Report on Form 10-K for the year ended December 31, 2020 was $2 million. At September 30, 2021, the aggregate amount of our accrual for estimated costs associated with the "Residential Loan Seller Demands" described in our Annual Report on Form 10-K for the year ended December 31, 2020 was $2 million, a portion of which is contingent on the successful completion of future residential loan purchase and sale transactions with certain counterparties. We believe we have either resolved or adequately accrued for any unresolved Residential Loan Seller Demands and that there are no other Residential Loan Seller Demands that are reasonably possible to result in a material loss.

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, 2021 and the three months ended September 30, 2020, 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 nine months ended September 30, 2020, 32.2 million of common shares related to the assumed conversion of our convertible notes were antidilutive and were excluded in the calculation of diluted earnings per share. For the three and nine months ended September 30, 2021, the number of outstanding equity awards that were antidilutive totaled 22,102 and 18,736, respectively. For the three and nine months ended September 30, 2020, the number of outstanding equity awards that were antidilutive totaled 13,560 and 15,457, respectively.

Stock Repurchases
In February 2018, our Board of Directors approved an authorization for the repurchase of our common stock, increasing the total amount authorized for repurchases of common stock to $100 million, and also authorized the repurchase of outstanding debt securities, including convertible and exchangeable debt. This authorization increased the previous share repurchase authorization approved in February 2016 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, 2021, we did not repurchase any shares. At September 30, 2021, $78 million of the current authorization remained available for the repurchase of shares of our common stock and we also continued to be authorized to repurchase outstanding debt securities.

Performance Stock Units (“PSUs”)
At September 30, 2021 and December 31, 2020, the target number of PSUs that were unvested was 955,710 and 978,735, respectively. Vesting for PSUs generally occurs at the end of three years from their respective grant dates based on various total shareholder return performance calculations, as discussed in our Annual Report on Form 10-K for the year ended December 31, 2020. With respect to PSUs granted in May 2018, the three-year performance period ended during the second quarter of 2021, resulting in the vesting of no shares of our common stock. During the second quarter of 2021, for PSUs granted in 2020, we adjusted the future amortization expense by $1 million to reflect our current estimate of the number of shares expected to vest in relation to the performance condition for the initial one-year vesting tranche.
Employee Stock Purchase Plan ("ESPP")
The ESPP allows a maximum of 850,000 shares of common stock to be purchased in aggregate for all employees. As of September 30, 2021 and December 31, 2020, 546,093 and 489,886 shares had been purchased, respectively, and there remained a negligible amount of uninvested employee contributions in the ESPP at September 30, 2021.

Note 22. Taxes
We believe that we have met all requirements for qualification as a REIT for federal income tax purposes. To qualify as a REIT, the Company must distribute at least 90% of its annual REIT taxable income and meet certain other requirements that relate to, among others, the assets it holds, the income it generates, and the composition of its stockholders.
For the nine months ended September 30, 2021 and 2020, we recognized a provision for income taxes of $14 million and a benefit from income taxes of $13 million, respectively. The following is a reconciliation of the statutory federal and state tax rates to our effective tax rate at September 30, 2021 and 2020.
Table 22.1 – Reconciliation of Statutory Tax Rate to Effective Tax Rate

|  | September 30, 2021 |  | September 30, 2020
Federal statutory rate |  | 21.0 | % |  | 21.0 | %
State statutory rate, net of Federal tax effect |  | 8.6 | % |  | 8.6 | %
Differences in taxable (loss) income from GAAP income |  | (13.1) | % |  | (23.6) | %
Change in valuation allowance |  | (6.8) | % |  | (4.0) | %
Dividends paid deduction (1) |  | (4.9) | % |  | — | %
Effective Tax Rate |  | 4.8 | % |  | 2.0 | %

(1)The dividends paid deduction in the effective tax rate reconciliation is generally representative of the amount of distributions to shareholders that reduce REIT taxable income. For the nine months ended September 30, 2020, the dividends paid deduction is 0% because there was no REIT taxable income available to apply against the dividends paid. This was due to our REIT incurring a taxable loss during the period.
We assessed our tax positions for all open tax years (i.e., Federal, 2017 to 2021, and State, 2016 to 2021) at September 30, 2021 and December 31, 2020, and concluded that we had no uncertain tax positions that resulted in material unrecognized tax benefits.
For the three months ended September 30, 2021, we reassessed the valuation allowance on our deferred tax assets ("DTAs") noting an increase in positive evidence related to our ability to utilize certain DTAs. The positive evidence includes significant revenue growth in recent quarters and expectations regarding future profitability at our TRS. After assessing both the positive and negative evidence, we determined it was more likely than not that we will realize all of our federal DTAs. Therefore, we reversed our federal valuation allowance of $17 million as a discrete benefit in the third quarter of 2021. In addition to the federal valuation allowance release, we determined it was more likely than not that we will realize a portion of our state DTAs and, as such, reversed $3 million of state valuation allowance as a discrete item in the third quarter of 2021. Consistent with prior periods, we continued to maintain a valuation allowance against the majority of our net state DTAs as realization of our state DTAs is dependent on generating sufficient taxable income in the same jurisdictions in which the DTAs exist and we project most of our state DTAs will expire prior to their utilization.
Note 23. Segment Information
Redwood operates in three segments: Residential Lending, Business Purpose Lending, and Third-Party Investments. For a full description of our segments, see Part I, Item 1—Business in our Annual Report on Form 10-K for the year ended December 31, 2020.
Segment contribution represents the measure of profit that management uses to assess the performance of our business segments and make resource allocation and operating decisions. Certain corporate expenses not directly assigned or allocated to one of our three segments, as well as activity from certain consolidated Sequoia entities, are included in the Corporate/Other column as reconciling items to our consolidated financial statements. These unallocated corporate expenses primarily include interest expense from our convertible notes and trust preferred securities, indirect general and administrative expenses and other expense.

Our Business
Redwood Trust, Inc., together with its subsidiaries, is a specialty finance company focused on several distinct areas of housing credit. Our operating platforms occupy a unique position in the housing finance value chain, providing liquidity to growing segments of the U.S. housing market not served by government programs. We deliver customized housing credit investments to a diverse mix of investors through our best-in-class securitization platforms, whole-loan distribution activities and our publicly-traded shares. Our consolidated investment portfolio has evolved to incorporate a diverse mix of residential, business purpose and multifamily investments. Our goal is to provide attractive returns to shareholders through a stable and growing stream of earnings and dividends, capital appreciation, and a commitment to technological innovation that facilitates risk-minded scale. We operate our business in three segments: Residential Lending, Business Purpose Lending, and Third-Party Investments. For a full description of our segments, see Part 1, Item 1—Business in our Annual Report on Form 10-K for the year ended December 31, 2020.
Cautionary Statement
This Quarterly Report on Form 10-Q and the documents incorporated by reference herein contain forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. 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, 2020, 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 (including trends driving the flow of capital in the housing finance market, our strategic initiatives designed to capitalize on those trends, our ability to attract capital to finance those initiatives, our approach to raising capital, our ability to pay dividends in the future, and the prospects for federal housing finance reform); (ii) statements related to our financial outlook and expectations for 2021 and future years; (iii) statements related to our opportunities for growth, including by continuing to creatively expand distribution channels for our loans products; (iv) statements related to our investment portfolio, including that there remains potential upside in our portfolio through a combination of accretable market discount and call rights that we control, and that we reinitiated our flow purchase arrangement with Point, providing us with continuing HEI acquisition and securitization opportunities; (v) statements related to our residential and business purpose lending platforms, including that we expect CoreVest to continue to consider issuing bridge loan securitizations in conjunction with our traditional SFR loan securitizations; (vi) statements relating to our estimate of our available capital (including that we estimate our available capital at September 30, 2021 was approximately $350 million); (vii) 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 2021 and at September 30, 2021, and expected fallout and the corresponding volume of residential mortgage loans expected to be available for purchase; (viii) statements we make regarding future dividends, including with respect to our regular quarterly dividends in 2021; and (ix) 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.
Many of the factors that could affect our actual results are summarized below. One of the most significant factors, however, is the ongoing impact of the pandemic on the United States economy, homeowners, renters of housing, the housing market, the mortgage finance markets and the broader financial markets. It is difficult to fully assess the impact of the pandemic at this time, including because of the uncertainty around the severity and duration of the pandemic domestically and internationally, as well as the uncertainty around the efficacy of Federal, State and local governments’ efforts to contain the spread of COVID-19 and respond to its direct and indirect impacts on many aspects of Americans’ lives and economic activity. Moreover, each of the factors summarized below is likely to also be impacted directly or indirectly by the ongoing impact of the pandemic and investors are cautioned to interpret substantially all of the risks identified in the Company’s previously published “Risk Factors” as being heightened as a result of the ongoing impact of the pandemic.
Important factors, among others, that may affect our actual results include:

OVERVIEW
Business Update
During the third quarter, we hosted Redwood’s third annual Investor Day. During our event we affirmed our commitment to our corporate mission to make quality housing, whether rented or owned, accessible to all American households, and discussed the Company's vision of being the leading operator and strategic capital provider driving sustainable innovation in housing finance.
We have significantly broadened our business within the housing market over the past several years. This includes expanding our mortgage banking platform and investment portfolio beyond the jumbo residential mortgage space, while maintaining the core competencies of the firm around our expertise in residential housing credit. Our expansion includes our acquisition of CoreVest in 2019 – which has now been part of our platform for two years – and investments in several other areas of housing finance. More recently, our approach to capital deployment has continued to evolve. Our progress this year growing our RWT Horizons initiative – investing in advanced technologies with the potential to transform our businesses – reflects an important step in that process. While our capital remains predominantly allocated to our operating businesses and investment portfolio, RWT Horizons reflects our belief in the strategic importance of innovation and partnership in driving profitable scale.
Our strategic vision is based upon the vast addressable market we see in front of us, driven by macroeconomic and market forces that have made liquidity sourced from the private markets essential for a robust housing finance system, for both consumers and investors alike. The recent modest increase in benchmark rates belies a lack of yield in the market that – but for some brief and notable intervals – has been persistent for over a decade. Taken together, this puts a premium on enterprises that can directly access markets efficiently and with discipline. We believe that these competencies, coupled with capital optimization and efficiency gains, will drive our financial results, and continuing to creatively expand distribution channels for mortgage loans we originate or acquire will be an important part of our evolution.
Turning to the third quarter of 2021, after a successful first half of the year, our team continued its strong performance. CoreVest maintained its momentum, funding $639 million of loans for the quarter, including $239 million in September alone. Our third quarter results saw strong contributions from both our SFR and Bridge lending teams, and we made key progress in our correspondent loan business, including our strategic investment in Churchill. Meanwhile, the Residential business identified $4.7 billion of loans for purchase in the third quarter (locked loans, unadjusted for fallout). Notwithstanding that benchmark interest rates hit lows not seen since February, almost 60% of our residential loan locks during the third quarter were on purchase-money loans, which we believe is indicative of the quality of our pipeline and our sellers.
Our investment portfolio remained in step with this operating progress, appreciating in value by approximately 2% during the third quarter of 2021. We believe there remains potential upside in our securities portfolio from a combination of accretable market discount and call rights that we control.
These factors contributed to another strong quarter of financial results, with GAAP earnings of $0.65 per diluted share, a 27% annualized return on equity for the third quarter of 2021. Book value increased 4.7% in the third quarter to $12.00 per share, contributing to an overall year-to-date increase of 21%. We declared a third quarter dividend of $0.21 per share and have now earned a 27% economic return year to date, which represents growth in GAAP book value combined with dividends paid.
Additionally, we executed a series of strategic and novel transactions across various disciplines within our firm that both positively contributed to earnings and provided indicators of our operating progress. Our Residential team completed a securitization leveraging blockchain technology for enhanced payment reporting for Sequoia investors. Historically, RMBS investors have needed to wait until well into the following month to see a month’s worth of remittance details on underlying loans. Liquid Mortgage – an early portfolio company of RWT Horizons – has coordinated with our sub-servicer to publish daily remittance information on a public blockchain. We believe this implementation is just the first step in the application of this type of technology to our business.
Next, we completed CoreVest’s first securitization of bridge loans, which priced competitively against comparable transactions in the market. This new form of distribution provides a valuable capital management tool with a 30-month reinvestment feature. We expect CoreVest to continue to consider issuing bridge loan securitizations in conjunction with our traditional single-family rental ("SFR") loan securitizations, having recently priced the 19th overall CAFL securitization in October 2021.
78

Finally, we co-sponsored a securitization backed entirely by residential Home Equity Investment contracts (“HEIs”). Co-sponsored with Point Digital, a financial technology company, this transaction allowed investors to participate in a new sector of the residential housing finance market that enables homeowners to participate in the benefits of home price appreciation without having to sell their homes or incur additional debt obligations. In parallel with this securitization, we renewed our flow purchase arrangement with Point, providing us with continuing HEI acquisition and securitization opportunities.
RWT Horizons also continued its investment activity, completing six investments during the third quarter while continuing to analyze a broad array of opportunities in the pipeline, including several in the climate analytics area, which continues to be of interest as traditional methods of predicting how climate change can impact property valuation and insurability continue to evolve. With a direct relationship to our firmwide ESG work, we expect to continue dedicating focus to this type of opportunity through RWT Horizons.
As we approach the end of 2021, we are proceeding cautiously. We see several macro and market risks ahead, including COVID-19 variants, rising inflation, central bank tapering (now officially signaled by the Federal Reserve) and Federal debt ceiling extension uncertainty, among others. More fundamentally, recent trends in unemployment claims data suggest that the economy is still in a recovery phase and the current economic situation is far from stable, notwithstanding consistent upward pressure on home prices and rents that has otherwise been favorable to our business results. Our interest rate, capital and broader risk management posture reflects this cautious view: while we have generated strong earnings thus far in 2021, we have done so with record levels of cash on hand – including $557 million at September 30, 2021.
We are also focused on making a positive impact for our people, our customers, our communities, and the overall society within which we operate. We believe this focus on a business model vision and a set of core values can produce long-term and sustainable benefits for all our stakeholders. Going forward, we expect to continue operating to fulfill our broadly-conceived mission, focusing on the significant addressable markets in front of us, embracing the cusp of innovation, running a business grounded in fundamentals and sound analysis, and nurturing a diverse talent bench engaged and aligned with our values.

Third Quarter Overview
The following table presents key financial metrics for the three and nine months ended September 30, 2021.
Table 1 – Key Financial Metrics

|  | Three Months Ended |  | Nine Months Ended
(In Thousands, except per Share Data) |  | September 30, 2021 |  | September 30, 2021
Net income per diluted common share |  | $ | 0.65 |  |  | $ | 2.03 |
Annualized GAAP return on equity |  | 26.7 | % |  | 29.6 | %

(1)Economic return on book value is based on the periodic change in GAAP book value per common share plus dividends declared per common share during the period.
•Our third quarter 2021 results reflect ongoing strength of our operating platforms with higher volumes and strong margins driving increased revenues, improved returns in our investment portfolio from more efficient financing, and a tax benefit realized during the quarter. These results, along with an increase in the value of our securities portfolio attributable to continued positive fundamental trends, contributed to a 4.7% increase in our book value per share during the quarter.
•In September 2021, we announced a 17% increase in our quarterly dividend to $0.21 per share for the third quarter of 2021.
•Our book value increased $0.54 per share to $12.00 per share during the third quarter of 2021, as basic earnings per share significantly exceeded our third quarter dividend of $0.21 per share.
•Our business purpose lending platform funded $639 million of business purpose mortgage loans in the third quarter, including $394 million of single-family rental loans and $245 million of residential bridge loans.
•During the third quarter of 2021, we locked a record $4.74 billion of jumbo loans with over 125 discrete sellers, jumbo loan purchase commitments were $3.29 billion, and we purchased $3.18 billion of residential jumbo loans.
•During the third quarter of 2021, we securitized $1.03 billion of loans through three securitizations across Residential and Business Purpose Lending, and distributed $2.43 billion of jumbo loans through whole loan sales.

•During the third quarter of 2021, we funded six venture investments through our RWT Horizons venture investment initiative.
•During the third quarter of 2021, we added over $350 million of financing capacity to support growth of our operating platforms and completed a new $100 million non-marginable term financing collateralized by retained securities in our investment portfolio.
•At September 30, 2021, our unrestricted cash was $557 million, and our estimated available capital was $350 million.

Net Interest Income
The increase in net interest income during the three-month periods was primarily due to higher average asset balances during the third quarter of 2021, as well as a higher net interest margin, driven by the combination of a lower average cost of funds and higher discount accretion on our available-for-sal e securities. For the nine-month periods, the decrease in net interest expense was primarily related to higher average asset balances during the first half of 2020, as we repositioned our portfolio during the second quarter of 2020, selling a significant amount of assets.
Additional detail on net interest income is provided in the “Net Interest Income” section that follows.
Mortgage Banking Activities, Net
The increase in income from mortgage banking activities during the three- and nine-month periods was primarily due to an increase in loan acquisition and origination volumes at both our residential and business purpose mortgage banking businesses during 2021, due to pandemic-related disruptions in 2020, which adversely impacted our origination volumes in 2020.
A more detailed analysis of the changes in this line item is included in the “Results of Operations b y Segment” section that follows.

Investment Fair Value Changes, Net
Investment fair value changes, net, is primarily comprised of the change in fair values of our portfolio investments accounted for under the fair value option and, prior to the second quarter of 2020, interest rate hedges associated with these investments. During the three and nine months ended September 30, 2021, positive investment fair value changes reflected continuing improvement in credit performance and spread tightening across our investment portfolio, particularly in our third-party re-performing loan ("RPL") and retained CAFL SFR securities. Additional detail on our investment fair value changes during 2021 is included in the “Results of Operations by Segment” section that follows.
During the three months ended September 30, 2020, investment fair value changes reflected increases in the fair value of our investment assets from improved credit performance and spread tightening. During the nine months ended September 30, 2020, the negative investment fair value changes reflected significant declines in the value of our investments in the first quarter of 2020 resulting from market dislocations caused by the pandemic.
Other Income
The increase in other income for the three- and nine-month periods was primarily the result of an increase in income from our MSR investments, which generally benefited from a stabilization in prepayment speeds during 2021.
Realized Gains, Net
During the three and nine months ended September 30, 2021, we realized gains of $7 million and $18 million, respectively, primarily resulting from the call of two and six seasoned Sequoia securitizations, respectively. During the three and nine months ended September 30, 2020, we realized gains of $1 million and $30 million, respectively, primarily resulting from the sale of AFS securities, and for the nine-month period, a $25 million gain from the repurchase of $125 million of convertible debt during the second quarter of 2020.
General and Administrative Expenses
The increase in general and administrative expenses for the three- and nine-month periods primarily resulted from increased accruals of variable compensation expense associated with improved financial results in 2021 as compared to 2020, as well as long-term incentive award expense from awards granted in the second half of 2020.
Loan Acquisition Costs
The increase in loan acquisition costs for the three- and nine-month periods was primarily due to higher loan origination volumes throughout 2021 as compared to 2020.
Other Expenses
The decrease in other expenses for the nine-month periods was primarily due to $89 million of goodwill impairment expense at our Business Purpose Lending segment recorded in the first quarter of 2020 that was taken as a result of the onset of pandemic- and liquidity-related disruptions.
Provision for Income Taxes
Our provision for income taxes is almost entirely related to activity at our taxable REIT subsidiaries, which primarily includes our mortgage banking activities and MSR investments, as well as certain other investment and hedging activities. For the three-month periods, our income tax provision decreased as we realized a $19 million benefit from the release of valuation allowance on a portion of our deferred tax assets. This decrease was partially offset by an increase in GAAP income recorded at our TRS and state taxes during 2021. For the nine-month periods, the tax provision in 2021 is reflective of the positive income earned at our taxable subsidiaries, partially offset by the benefit from the release of valuation allowance and higher state taxes, as compared to a tax benefit in 2020 reflective of a net loss incurred in that period.
For additional detail on income taxes, see the “Taxable Income and Tax Provision” section that follows.

Results of Operations by Segment
We report on our business using three distinct segments: Residential Lending, Business Purpose Lending, and Third-Party Investments. For additional information on our segments, refer to Note 23 of our Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q. The following table presents the segment contribution from our three segments reconciled to our consolidated net income for the three and nine months ended September 30, 2021 and 2020.

The following sections provide a discussion of the results of operations at each of our three business segments for the three and nine months ended September 30, 2021.
The decrease in net expense from Corporate/Other for the three-month periods was primarily due to the reversal of $19 million of valuation allowance on our deferred tax assets in the third quarter of 2021. This decrease was partially offset by higher accruals of variable compensation expense associated with improved financial results in 2021. The increase in net expense for the nine-month periods was primarily due to a $25 million gain associated with the repurchase of $125 million of convertible debt in the second quarter of 2020.
Residential Lending Segment
Overview
Our Residential Lending segment generated $39 million of net income during the third quarter of 2021, driven primarily by $40 million of mortgage banking income and $12 million of net interest income from investments. Mortgage banking income increased from the second quarter of 2021, as loan purchase commitments of $3.3 billion in the third quarter were 20% higher than the second quarter and margins improved from the second quarter. Net interest income from investments increased approximately $5 million in the third quarter of 2021 from the second quarter of 2021, due to increased discount amortization on our available-for-sale securities.
Our Residential Lending segment generated $31 million of net income during the second quarter of 2021, driven primarily by $27 million of mortgage banking income and $6 million of net interest income from investments. Mortgage banking income decreased from the first quarter of 2021, as loan purchase commitments of $2.7 billion in the second quarter were 22% lower than the first quarter and margins normalized towards the high end of our historic target range.
Our Residential Lending segment generated $53 million of net income during the first quarter of 2021, driven primarily by $64 million of mortgage banking income and $6 million of net interest income from investments. Mortgage banking income increased significantly during the quarter, as loan purchase commitments increased 41% from the fourth quarter of 2020 to $3.51 billion, and gross margins nearly doubled.

Loan purchase commitments entered into |  | $ | 3,288,102 |  |  | $ | 9,541,499 |

Mortgage banking income is comprised of net interest income from loans held-for-sale in inventory and mortgage banking activities. Income from mortgage banking activities is comprised of mark-to-market adjustments on loans from the time they are purchased to when they are sold, mark-to-market adjustments on new and outstanding loan purchase commitments, gains/losses from associated hedges, and other miscellaneous income/expenses (see Note 19 of our Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for further detail).
During the three months ended September 30, 2021, our residential mortgage loan conduit locked $4.74 billion of loans ($3.29 billion adjusted for expected pipeline fallout - i.e, loan purchase commitments), including $4.21 billion of Select loans and $0.53 billion of Choice loans, and purchased $3.18 billion of loans. Approximately 59% of loans locked in the third quarter were purchase-money loans and 41% were refinancings. During the three months ended September 30, 2021, we distributed $2.43 billion of loans through whole loan sales, and completed one securitization backed by $449 million of loans (unpaid principal balance).
At September 30, 2021, we had $1.34 billion of loans in inventory on our balance sheet, our loan pipeline included $2.77 billion of loans identified for purchase (locked loans, unadjusted for fallout), and we had entered into forward sale agreements for $662 million of loans.
Our gross margin (mortgage banking income earned in the period divided by loan purchase commitments entered into during the period) for the three months ended September 30, 2021 was 122 basis points, up from 98 basis points in the second quarter of 2021.
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, 2021, we had residential warehouse facilities outstanding with seven different counterparties, with $2.70 billion of total capacity and $1.36 billion of available capacity. These included non-marginable (i.e., not subject to margin calls based on the market value of the underlying collateral that is non-delinquent) facilities with $1.18 billion of total capacity and marginable facilities with $1.53 billion of total capacity.

(2)Excludes $5 million of trading securities that are designated as hedges for our mortgage banking operations and are not considered part of our investment portfolio.
(3)Represents our retained economic investment in the consolidated Sequoia securitization VIEs. For GAAP purposes, we consolidated $2.48 billion of loans and $2.24 billion of ABS issued associated with these investments at September 30, 2021.
During the third quarter of 2021, we purchased $66 million of loans from Sequoia securitizations we called, and we retained $2 million of securities from one Sequoia securitization we completed during the quarter. During the second quarter of 2021, we purchased $83 million of loans from Sequoia securitizations we called, and we retained $8 million of securities from three Sequoia securitizations we completed during the quarter. During the first quarter of 2021, we sold $4 million of securities from our residential lending investment portfolio and retained $8 million of securities from two Sequoia securitizations we completed during the quarter. See the "Investments Detail" section that follows for additional details on our investments and their associated borrowings.
During the third quarter of 2021, net interest income from our residential lending investment portfolio was $12 million, which increased $5 million from the second quarter of 2021, and other income was $1 million in the third quarter of 2021, consistent with the second quarter of 2021. The increase in net interest income was primarily due to higher discount accretion income on our available-for-sale securities, driven by expectations for certain of our retained Sequoia securities to be called over the next several quarters, affecting our cash flow forecasts and effective yields for those investments.
The following table presents the components of investment fair value changes for our Residential Lending segment by investment type for the three and nine months ended September 30, 2021.

Strengthening credit performance helped drive spreads tighter during the three-and nine-month periods for most of our subordinate securities, which resulted in net positive fair value changes for our residential lending investments. Additionally, during the first nine months of 2021, most of our investment securities experienced elevated prepayments, which generally benefited our subordinate securities, but negatively impacted our interest-only and certificated servicing securities, causing a net negative fair value change for our trading securities.
Business Purpose Lending Segment
Overview
Our Business Purpose Lending segment generated $32 million of net income during the third quarter of 2021, driven primarily by $32 million of mortgage banking income and $18 million of net interest income from investments. Our business purpose investments saw an increase in interest income in the third quarter from a higher average balance of investments and lower cost of funds, compared to the second quarter of 2021, and increased positive fair value changes due to continued strength in credit performance and spread tightening.
Our Business Purpose Lending segment generated $33 million of net income during the second quarter of 2021, driven primarily by $35 million of mortgage banking income and $15 million of net interest income from investments. Business purpose mortgage banking income in the second quarter of 2021 benefited from a 37% increase in origination volume from the first quarter of 2021 and modest spread tightening on securitization execution during the second quarter. Our business purpose investments saw an increase in interest income in the second quarter from a higher average balance of investments compared to the first quarter of 2021 and increased positive fair value changes due to continued spread tightening.
Our Business Purpose Lending segment generated $21 million of net income during the first quarter of 2021, driven primarily by $22 million of mortgage banking income and $13 million of net interest income from investments. Business purpose mortgage banking income normalized in the first quarter of 2021, relative to the third and fourth quarters of 2020, as more modest spread tightening on securitization execution during the quarter had a reduced impact to the valuation of our loans held in inventory at the beginning of the quarter. Net interest income from BPL investments increased from the fourth quarter of 2020 due to higher yield maintenance income on our SFR securities resulting from faster prepayments, and reduced debt costs on our bridge loan portfolio resulting from a decrease in leverage on these assets.

(1)We originate bridge loans at our TRS and then transfer them to our REIT. Origination fees and any fair value changes on these loans prior to transfer are recognized within Mortgage banking activities, net on our consolidated statements of income (loss). Once the loans are transferred to our REIT, they are classified as held-for-investment, with subsequent fair value changes generally recorded through Investment fair value changes, net on our consolidated statements of income (loss). For bridge loans held at our REIT that are transferred into our CAFL bridge securitization, we record any changes in fair value from the date of origination or purchase to the time of securitization as Mortgage banking activities, net on our consolidated statements of income (loss). Once loans are transferred into this securitization, any changes in fair value are recorded through Investment fair value changes, net on our consolidated statements of income (loss). For the carrying value and activity of our bridge loans held-for-investment, see the Investments section that follows.
(2)For single-family rental loans, amounts represent the fair value of transfers of loans from held-for-sale to held-for-investment, including when loans are securitized (and consolidated for GAAP purposes). For bridge loans, represents the transfer of loans originated at our TRS to our REIT as described in preceding footnote.
Business purpose mortgage banking income was $23 million, $35 million and $32 million in the first, second and third quarters of 2021, respectively. Mortgage banking income is comprised of net interest income from single-family rental loans held-for-sale in inventory and mortgage banking activities income from single family rental and bridge loans (see Note 19 of our Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for further detail on mortgage banking activities).
Business purpose funding volumes increased steadily through the first nine months of 2021. These growing volumes, along with improved SFR securitization execution in the second and third quarters of 2021, drove strong mortgage banking income results for those periods. Approximately 66% of total origination volumes in the third quarter were from repeat borrowers.
We utilize a combination of capital and loan warehouse facilities to manage our inventory of single-family rental loans that we hold for sale. At September 30, 2021, we had business purpose warehouse facilities outstanding with four different counterparties, with $1.30 billion of total capacity (used for both SFR and bridge loans) and $663 million of available capacity (inclusive of capacity on non-recourse facilities). All of these facilities are non-marginable (i.e., not subject to margin calls based on the market value of the underlying collateral that is non-delinquent).

Spreads tightened throughout 2021 for our CAFL subordinate securities, with positive fair value changes for these assets more than offsetting the decline in the value of our CAFL interest-only securities from a reduction in their basis through the receipt of regular cash flows. We also had positive resolutions on several previously delinquent bridge loans during 2021, resulting in positive fair value changes for recoveries in excess of carrying values.

Third-Party Investments Segment
Overview
Our Third-Party Investments segment generated $30 million of net income during the third quarter of 2021, driven primarily by $21 million of positive investment fair value changes and $12 million of net interest income. Our Third-Party Investments segment generated $54 million of net income during the second quarter of 2021, driven primarily by $42 million of positive investment fair value changes and $12 million of net interest income, and generated $50 million of net income during the first quarter of 2021, driven primarily by $40 million of positive investment fair value changes and $12 million of net interest income. Positive investment fair value changes in 2021 reflected continuing improvement in credit performance and spread tightening, particularly for our RPL and multifamily securities.

Continued strengthening of credit and elevated prepayment speeds helped drive credit spreads tighter on our third-party assets in 2021, in particular for our investments in re-performing loan assets (primarily represented by our net investment in Freddie Mac SLST entities in the table above). HEI valuations benefited from our securitization of HEIs in the third quarter of 2021. The decline in value of our Servicer advance investments and excess MSRs is primarily attributable to a reduction in their basis through the receipt of regular cash flows.

(1)Investment thickness represents the average size of the subordinate securities we own as investments in securitizations, relative to the average overall size of the securitizations. For example, if our investment thickness (of first-loss securities) with respect to a particular securitization is 10%, we have exposure to the first 10% of credit losses resulting from loans underlying that securitization. We generally own first loss positions in Sequoia, RPL and CAFL securities. We own both first loss and mezzanine positions (positions credit enhanced by subordinate securities) in multifamily and other third-party securities.
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. At September 30, 2021, we had short-term debt incurred through repurchase facilities of $80 million with three different counterparties, which was secured by $108 million of real estate securities (including securities owned in consolidated securitization entities).
At September 30, 2021, real estate securities with a fair value of $504 million (including securities owned in consolidated Sequoia and CAFL securitization entities), were financed with long-term, non-mark-to-market recourse debt through our subordinate securities financing facilities. Additionally, at September 30, 2021, we had $451 million of re-performing loan securities financed with $161 million of non-recourse securitization debt. The remaining $297 million of our securities, including certain securities we own that were issued by consolidated securitization entities, were financed with capital.

(1)We originate bridge loans at our TRS and then transfer them to our REIT. Origination fees and any fair value changes on these loans prior to transfer are recognized within Mortgage banking activities, net on our consolidated statements of income (loss). Once the loans are transferred to our REIT, they are classified as held-for-investment, with subsequent fair value changes generally recorded through Investment fair value changes, net on our consolidated statements of income (loss). For bridge loans held at our REIT that are transferred into our CAFL bridge securitization, we record any changes in fair value from the date of origination or purchase to the time of securitization as Mortgage banking activities, net on our consolidated statements of income (loss). Once loans are transferred into this securitization, any changes in fair value are recorded through Investment fair value changes, net on our consolidated statements of income (loss). For the carrying value and activity of our bridge loans held-for-investment, see the Investments section that follows.
Our $825 million of b ridge loans held-for-investment at September 30, 2021 were comprised of first-lien, interest-only loans with a weighted average c oupon of 7.48% and original maturities of six to 24 months. At origination, the weighted average FICO score of borrowers backing these loans was 741 and the weighted average LTV ratio of these loans was 68%. At September 30, 2021, of the 1,092 loans in this portfolio, 34 of these loans with an aggregate fair value of $23 million and an aggregate unpaid principal balance of $26 million were in foreclosure, of which 35 loans with an aggregate fair value of $27 million and an unpaid principal balance of $30 million were greater than 90 days delinquent.
We finance our bridge loans with a combination of recourse, non-marginable warehouse facilities and non-recourse, non-marginable warehouse facilities. At September 30, 2021, we had $83 million of debt incurred through short-term warehouse facilities with one different counterparty, which was secured by $127 million of loans, and $279 million of debt incurred through long-term facilities with three different counterparties, which was secured by $374 million of loans. Additionally, in the third quarter of 2021, we completed a securitization of CoreVest bridge loans. The ABS issued by this securitization were backed by assets including $276 million of bridge loans and $28 million of restricted cash at September 30, 2021. The securitization is structured with $300 million of total funding capacity and a feature to allow reinvestment of loan payoffs for the first 30 months of the transaction (through March 2024).

(1)At September 30, 2021 (our "Balance at End of Period"), Third-party investments presented in this table includes $188 million of servicing investments owned in our consolidated Servicing Investment entities. At September 30, 2021, our economic investment in these entities was $60 million (for GAAP purposes, we consolidated $188 million of servicing investments, $152 million of non-recourse short-term securitization debt, as well as other assets and liabilities for these entities). Additionally, At September 30, 2021, Third-party investments presented in this table includes $167 million of HEIs owned in our consolidated Point HEI entity. At September 30, 2021, our economic investment in this entity was $10 million (for GAAP purposes, we consolidated $167 million of HEIs and $145 million of ABS issued, as well as other assets and liabilities for this entity).
During the third quarter of 2021, in conjunction with co-sponsoring a securitization of HEIs, we purchased $122 million of additional HEIs from other contributors to the securitization (included within "Third-Party Investments" in the table above), then transferred $170 million of HEIs to the Point HEI securitization entity and issued $146 million of ABS. We retained subordinate certificates from the entity valued at $10 million as of September 30, 2021, representing our economic interest in the entity.
During the first nine months of 2021, in addition to the HEIs acquired in the third quarter described above, other new/ additional investments included MSRs retained from whole loan sales at our Residential Segment and strategic investments through our RWT Horizons venture investment strategy within Corporate/Other.
During the first nine months of 2021, reductions in investments for Third-Party Investments was primarily attributable to the recovery of servicing advances within our consolidated servicing VIEs. Our economic investment in these entities was $60 million at September 30, 2021 and $68 million at December 31, 2020.

Income Taxes
Taxable Income, REIT Status and Dividend Characterization
As a REIT, under the Internal Revenue Code, Redwood is required to distribute to shareholders at least 90% of its annual REIT taxable income, excluding net capital gains, and meet certain other requirements that relate to, among other matters, the assets it holds, the income it generates, and the composition of its stockholders. To the extent Redwood retains REIT taxable income, including net capital gains, it is taxed at corporate tax rates. Redwood also earns taxable income at its taxable REIT subsidiaries (TRS), which it is not required to distribute under the Internal Revenue Code.
In September 2021, our Board of Directors declared a regular dividend of $0.21 per share for the third quarter of 2021, which was paid on September 30, 2021 to shareholders of record on September 23, 2021. As of September 30, 2021, our year-to-date dividend distributions of $0.55 per share exceeded our minimum distribution requirements and we believe that we have met all requirements for qualification as a REIT for federal income tax purposes. Many requirements for qualification as a REIT are complex and require analysis of particular facts and circumstances. Often there is only limited judicial or administrative interpretive guidance and as such there can be no assurance that the Internal Revenue Service or courts would agree with our various tax positions. If we were to fail to meet all the requirements for qualification as a REIT and the requirements for statutory relief, we would be subject to federal corporate income tax on our taxable income and we would not be able to elect to be taxed as a REIT for four years thereafter. Such an outcome could have a material adverse impact on our consolidated financial statements.
While our minimum REIT dividend requirement is generally 90% of our annual REIT taxable income, we carried a $37 million federal net operating loss carry forward (NOL) into 2021 at our REIT that affords us the ability to retain REIT taxable income up to the NOL amount, tax free, rather than distributing it as dividends. Federal income tax rules require the dividends paid deduction to be applied to reduce REIT taxable income before the applicability of NOLs is considered; therefore, REIT taxable income must exceed our dividend distribution for us to utilize a portion of our NOL and any remaining NOL amount will carry forward into future years.
We currently expect all or nearly all of our 2021 dividend distributions to be taxable as ordinary income for federal income tax purposes. Any remaining amount is currently expected to be characterized as a return of capital, which in general is nontaxable (provided it does not exceed a shareholder's tax basis in Redwood shares) and reduces a shareholder's basis in Redwood shares (but not below zero). To the extent such distributions exceed a shareholder's basis in Redwood shares, such excess amount would be taxable as capital gain. Under the federal income tax rules applicable to REITs, none of Redwood’s 2021 dividend distributions are currently expected to be characterized as long-term capital gain dividends. The income or loss generated at our TRS will not directly affect the tax characterization of our 2021 dividends; however, any dividends paid from our TRS to our REIT would allow a portion of our REIT’s dividends to be classified as qualified dividends.
Tax Provision under GAAP
For the three and nine months ended September 30, 2021, we recorded a tax benefit of $4 million and a tax provision of $14 million, respectively. For the three and nine months ended September 30, 2020, we recorded a tax provision of $9 million and a tax benefit of $13 million, respectively. 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. For the nine-month periods, the switch to a tax provision from a tax benefit year-over-year was primarily the result of GAAP income being recorded at our TRS during this period in 2021 versus GAAP losses being recorded at our TRS during this period in 2020. For the three-month periods, the switch to a tax benefit from a tax provision year-over-year was due to the release of valuation allowance on a portion of our deferred tax assets, partially offset by an increase in state taxes. While our TRS effective tax rate in the prior year approximated the federal statutory corporate tax rate (due to state NOL carryforwards), for 2021 and 2022 we expect it to increase (exclusive of the valuation allowance release) due to California’s temporary suspension of net operating loss carryforwards.
Realization of our deferred tax assets ("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, 2020, we reported net federal ordinary and capital DTAs with a full valuation allowance of $17 million recorded against our net federal ordinary DTAs based on our determination that their realization was not assured. However, no valuation allowance was recorded against our net federal capital DTAs as we currently expect to utilize these DTAs due to our ability to recognize capital losses and carry them back to prior years. At December 31, 2020, we reported a valuation allowance of $134 million recorded against our net state DTAs.
98

For the three months ended September 30, 2021, we reassessed the valuation allowance noting the increase in positive evidence related to our ability to utilize certain deferred tax assets. The positive evidence includes significant revenue growth and expectations regarding future profitability at our TRS. After assessing both the positive evidence and negative evidence, we determined it was more likely than not that we will realize all of our federal deferred tax assets. Therefore, we reversed our federal valuation allowance of $17 million as a discrete benefit in the third quarter of 2021. In addition to the federal valuation allowance release, we determined it was more likely than not that we will realize a portion of our state deferred assets and, as such, reversed $3 million of state valuation allowance as a discrete item in the third quarter of 2021. Consistent with prior periods, we continued to maintain a valuation allowance against the majority of our net state DTAs as realization of our state DTAs is dependent on generating sufficient taxable income in the same jurisdictions in which the DTAs exist and we project most of our state DTAs will expire prior to their utilization.

LIQUIDITY AND CAPITAL RESOURCES
Summary
In addition to the proceeds from equity and debt capital-raising transactions, 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, proceeds from the sale of portfolio assets, and cash generated from our operating activities. Our most significant uses of cash are to purchase and originate mortgage loans for our mortgage banking operations, to purchase investment securities and make other investments, to repay principal and interest on our debt, to meet margin calls associated with our debt and other obligations, to make dividend payments on our capital stock, and to fund our operations.
At September 30, 2021, our total capital was $2.03 billion and included $1.38 billion of equity capital and $652 million of convertible notes and long-term debt on our consolidated balance sheet, including $199 million of convertible debt due in 2023, $150 million of convertible debt due in 2024, $172 million of exchangeable debt due in 2025, and $140 million of trust-preferred securities due in 2037.
As of September 30, 2021, our unrestricted cash was $557 million, and we estimate we had approximately $350 million of available capital. While we believe our available cash is sufficient to fund our operations, we may raise equity or debt capital from time to time to increase our unrestricted cash and liquidity, to repay existing debt, to make long-term portfolio investments, to fund strategic acquisitions and investments, or for other purposes. To the extent we seek to raise additional capital, our approach will continue to be based on what we believe to be in the best interests of the company.
In the discussion that follows and throughout this document, we distinguish between marginable and non-marginable debt. When we refer to non-marginable debt and marginable debt, we are referring to whether or not such debt is subject to market value-based margin calls on underlying collateral that is non-delinquent. If a mortgage loan is financed under a marginable warehouse facility, to the extent the market value of the loan declines (which market value is generally determined by the counterparty under the facility), we will be subject to a margin call, meaning we will be required to either immediately reacquire the loan or meet a margin requirement to pledge additional collateral, such as cash or additional residential loans, in an amount at least equal to the decline in value. Non-marginable debt may be subject to a margin call due to delinquency of the mortgage or security being financed, or a decline in the value of the underlying asset securing the collateral. For example, we could be subject to a margin call on non-marginable debt if an appraisal or broker price opinion indicates a decline in the value of the property securing the mortgage loan that is financed by us under a loan warehouse facility.
We also distinguish between recourse and non-recourse debt. When we refer to non-recourse debt, we mean debt that is payable solely from the assets pledged to secure such debt, and under which debt no creditor or lender has direct or indirect recourse to us, or any other entity or person (except for customary exceptions for fraud, acts of insolvency, or other "bad acts"), if such assets are inadequate or unavailable to pay off such debt.
We are subject to risks relating to our liquidity and capital resources, including risks relating to incurring debt under residential 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, 2021
Cash flows from our mortgage banking activities and our investments can be volatile from quarter to quarter depending on many factors, including the profitability of mortgage banking activities, the timing and amount of securities acquisitions, sales and repayments, 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.
Cash Flows from Operating Activities
Cash flows from operating activities were negative $3.78 billion during the nine months ended September 30, 2021. This amount includes the net cash utilized during the period from the purchase and sale of residential mortgage loans and the origination and sale of our business purpose loans associated with our mortgage banking activities. Purchases of loans are financed to a large extent with short-term and long-term debt, for which changes in cash are included as a component of financing activities. Excluding cash flows from the purchase, origination, sale, and principal payments of loans classified as held-for-sale, cash flows from operating activities were positive $84 million and positive $94 million during the first nine months of 2021 and 2020, respectively.
100

Cash Flows from Investing Activities
During the nine months ended September 30, 2021, our net cash provided by investing activities was $1.36 billion and primarily resulted from proceeds from principal payments on loans held-for-investment. Although we generally intend to hold our loans and investment securities as long-term investments, we may sell certain of these assets in order to manage our liquidity ne eds and interest rate risk, to meet other operating objectives, and to adapt to market conditions.
Because many of our investment securities and loans are financed through various borrowing agreements, a significant portion of the proceeds from any sales or principal payments of these assets are generally used to repay balances under these financing sources. Similarly, all or a significant portion of cash flows from principal payments of loans at consolidated securitization entities would generally be used to repay ABS issued by those entities.
As presented in the "Supplemental Noncash Information" subsection of our consolidated statements of cash flows, during the nine months ended September 30, 2021, we transferred loans between held-for-sale and held-for-investment classification and retained securities from securitizations we sponsored, which represent significant non-cash transactions that were not included in cash flows from investing activities.
Cash Flows from Financing Activities
During the nine months ended September 30, 2021, our net cash provided by financing activities was $2.52 billion. This primarily resulted from $1.40 billion of proceeds from net short-term debt borrowings used to finance higher levels of loan inventory for our mortgage banking businesses, particularly for residential loans held-for-sale, as that business has seen a sustained increase in acquisition volumes. Additionally, $1.27 billion of net proceeds were generated from ABS issued. These cash inflows were partially offset by $107 million of net repayments of long-term debt.
During the nine months ended September 30, 2021, we declared dividends of $0.55 per common share. On September 13, 2021, the Board of Directors declared a regular dividend of $0.21 per share for the third quarter of 2021, which was paid on September 30, 2021 to shareholders of record on September 23, 2021.
In accordance with the terms of our outstanding deferred stock units, cash-settled deferred stock units, and restricted stock units, which are generally long-term compensation awards, each time we declare and pay a dividend on our common stock, we are required to make a dividend equivalent cash payment in that same per share amount on each outstanding deferred stock unit, cash-settled deferred stock unit, and restricted stock unit.
Repurchase Authorization
In February 2018, our Board of Directors approved an authorization for the repurchase of our common stock, increasing the total amount authorized for repurchases of common stock to $100 million, and also authorized the repurchase of outstanding debt securities, including convertible and exchangeable debt. This authorization increased the previous share repurchase authorization approved in February 2016 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, 2021, we did not repurchase any shares. At September 30, 2021, $78 million of the current authorization remained available for the repurchase of shares of our common stock and we also continued to be authorized to repurchase outstanding debt securities. Like other investments we may make, any repurchases of our common stock or debt securities under this authorization would reduce our available capital and unrestricted cash described above.
Loan Warehouse Facilities
We maintain loan warehouse facilities to finance our residential jumbo loan inventory, SFR loan inventory and for our bridge loan investments. These facilities can be classified as short-term or long-term depending on their specific terms and provisions. At September 30, 2021, we had residential warehouse facilities outstanding with seven different counterparties, with $2.70 billion of total capacity and $1.36 billion of available capacity. These included non-marginable facilities with $1.18 billion of total capacity and marginable facilities with $1.53 billion of total capacity. At September 30, 2021, we had business purpose warehouse facilities outstanding with four different counterparties, with $1.30 billion of total capacity and $663 million of available capacity. All $1.30 billion of these facilities are non-marginable.
101

Short-Term Debt
In the ordinary course of our business, we utilize several different types of borrowing facilities and use cash borrowings under these facilities to, among other things, fund the acquisition of loans (including those we acquire and originate in anticipation of securitization), finance investments in securities, BPL bridge loans and other investments, and otherwise fund our business and operations. At September 30, 2021, we had $1.75 billion of short-term debt outstanding. During the first nine months of 2021, the highest balance of our short-term debt outstanding was $2.66 billion.
For further detail on our short-term debt, see Note 13 of our Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Long-Term Debt
The following discusses significant activity related to our long-term debt during the first nine months of 2021. For further detail on our long-term debt, see Note 15 of our Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Recourse Subordinate Securities Financing
In the third quarter of 2021, a subsidiary of Redwood entered into a repurchase agreement providing non-marginable recourse debt financing of certain securities retained from our consolidated CAFL securitizations. The financing is guaranteed by Redwood, with an interest rate of approximately 4.75% through June 2024. The financing facility may be terminated, at our option, in June 2023, and has a final maturity in June 2026, provided that the interest rate on amounts outstanding under the facility increases between June 2024 and June 2026.
Non-Recourse BPL Financing Facilities
In the third quarter of 2021, we reclassified one of our non-recourse facilities from long-term to short-term debt as the maturity of this facility was less than one year at September 30, 2021.
In the second quarter of 2021, we repaid one of our non-recourse BPL financing facilities that had a balance of $242 million at March 31, 2021, and entered into a new non-recourse facility to finance business purpose bridge loans with a total borrowing capacity of $250 million.
Recourse BPL Financing Facilities
In the second quarter of 2021, we reclassified one of our recourse facilities with a borrowing capacity of $450 million from short-term to long-term debt as we amended the terms of this facility, including an extension of its maturity.
Asset-Backed Securities Issued
During the three and nine months ended September 30, 2021, we issued $1.19 billion and $2.82 billion of ABS through our consolidated securitization entities, respectively. This included $583 million and $1.01 billion of CAFL ABS issued during the three and nine months ended September 30, 2021, respectively, and $462 million and $1.66 billion of Sequoia ABS issued during the three and nine months ended September 30, 2021, respectively. Additionally, during the three months ended September 30, 2021, we issued $146 million of Point ABS. For further detail on our Asset-backed Securities Issued, see Note 14 of our Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Other Commitments and Contingencies
For additional information on commitments and contingencies that could impact our liquidity and capital resources, see Note 16 of our Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q, which supplements the disclosures included in Note 16 to the Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.

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 and origination of residential and business purpose mortgage loans (including those we acquire and originate 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. Recourse 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, 2020, under the caption “Risks Relating to Debt Incurred under Short- and Long-Term Borrowing Facilities,” and under the caption “Our use of financial leverage exposes us to increased risks, including liquidity risks from margin calls and potential breaches of the financial covenants under our borrowing facilities, which could result in our being required to immediately repay all outstanding amounts borrowed under these facilities and these facilities being unavailable to use for future financing needs, as well as triggering cross-defaults under other debt agreements” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2020. Many of the risks described above materialized during the first quarter of 2020 as a result of pandemic- and liquidity-related disruptions and their impacts on the economy and financial markets, as described under the heading “Management's Discussion and Analysis of Financial Condition and Results of Operations” within our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.
Our sources of debt financing include secured borrowings under residential and business purpose mortgage loan warehouse facilities (including recourse and non-recourse warehouse facilities), short-term securities repurchase facilities, a $10 million committed line of short-term secured credit from a bank, short-term servicer advance financing, a secured, revolving debt facility collateralized by mortgage servicing rights, and subordinate securities financing facilities.
Aggregate borrowing limits are stated under certain of these facilities, and certain other facilities have no stated borrowing limit, but many of the facilities are 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).
Under many of our mortgage loan warehouse facilities, our short-term securities repurchase facilities, and our secured, revolving debt facility collateralized by mortgage service rights, while transferred or pledged assets are financed under the facility, to the extent the value of the assets, or the collateral underlying those 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. During the second quarter of 2020, we amended several of our mortgage loan warehouse facilities to revise these margin call provisions to remove obligations to make margin calls for changes in the market value of transferred or pledged assets, which determinations of market value were generally within the sole discretion of the lending counterparty. Under these revised agreements, if the estimated value of a property securing a financed mortgage loan declines, based on, for example, an appraisal or broker-price opinion, then the creditor may demand that we transfer additional collateral to the creditor (in the form of cash, U.S. Treasury obligations (in certain cases), or additional residential mortgage loans) with a value equal to the amount of the decline. Of our active financing arrangements with outstanding balances at September 30, 2021, only our short-term securities repurchase facilities (with $80 million of borrowings outstanding at September 30, 2021), and four of our residential mortgage loan warehouse facilities (with $618 million of borrowings outstanding at September 30, 2021) retain market-value based margin call provisions.
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, 2020 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, 2020 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.”
103

Because many of these borrowing 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, 2020 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, 2020 under the heading “Market Risks.” In addition, with respect to mortgage 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, 2020 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, 2020 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.
At September 30, 2021, 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 Redwood, at September 30, 2021 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 Redwood, at September 30, 2021 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.
104

OFF-BALANCE SHEET ARRANGEMENTS AND CONTRACTUAL OBLIGATIONS
In the normal course of business, we enter into transactions that may require future cash payments. As required by GAAP, some of these obligations are recorded on the balance sheet, while others are off-balance sheet or recorded on the balance sheet in amounts different from the full contract or notional amount of the transaction.
For additional information on our contractual obligations, see the Off-Balance Sheet Arrangements and Contractual Obligations section in the MD&A included in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2020.
For additional information on our commitments and contingencies as of September 30, 2021, see Note 16 of our Notes to Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.
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 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, 2020. 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, 2020.
In addition to the regular volatility we may experience on a quarterly basis, the ongoing impact of the pandemic on the United States economy, homeowners, renters of housing, the housing market, the mortgage finance markets and the broader financial markets, has caused additional volatility impacting many of our estimates. It is difficult to fully assess the impact of the pandemic at this time, including because of the uncertainty around the severity and duration of the pandemic domestically and internationally, as well as the uncertainty around the efficacy of Federal, State and local governments’ efforts to contain the spread of the pandemic and respond to its direct and indirect impacts on many aspects of Americans’ lives and economic activity. Continued volatility resulting from the pandemic could impact our critical estimates and lead to significant period-to-period earnings volatility.
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, 2020.
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, 2020.
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.
105

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, 2020, 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, 2020.
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 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
During the three months ended September 30, 2021, we did not sell any equity securities that were not registered under the Securities Act of 1933, as amended.
In February 2018, our Board of Directors approved an authorization for the repurchase of our common stock, increasing the total amount authorized for repurchases of common stock to $100 million, and also authorized the repurchase of outstanding debt securities, including convertible and exchangeable debt. This authorization increased the previous share repurchase authorization approved in February 2016 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 months ended September 30, 2021, we did not repurchase any shares. At September 30, 2021, $78 million of this current authorization remained available for the repurchase of shares of our common stock and we also continued to be authorized to repurchase outstanding debt securities.
