Accounting Policies [Abstract] |
Basis of Presentation | Basis of PresentationThe consolidated financial statements presented herein are at September 30, 2020 and December 31, 2019, and for the three and nine months ended September 30, 2020 and 2019. 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, 2019. In the opinion of management, all normal and recurring adjustments to present fairly the financial condition of the company at September 30, 2020 and results of operations for all periods presented have been made. The results of operations for the three and nine months ended September 30, 2020 should not be construed as indicative of the results to be expected for the full year.
Principles of Consolidation | Principles of Consolidation In accordance with GAAP, we determine whether we must consolidate transferred financial assets and variable interest entities (“VIEs”) for financial reporting purposes. We currently consolidate the assets and liabilities of certain Sequoia securitization entities issued prior to 2012 where we maintain an ongoing involvement ("Legacy Sequoia"), as well as entities formed in connection with the securitization of Redwood Choice expanded-prime loans ("Sequoia Choice"). We also consolidate the assets and liabilities of certain Freddie Mac K-Series and Freddie Mac Seasoned Loans Structured Transaction ("SLST") securitizations we invested in. Finally, we consolidated the assets and liabilities of certain CoreVest American Finance Lender ("CAFL") securitizations beginning in the fourth quarter of 2019, in connection with our acquisition of CoreVest. 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 the consolidated Sequoia and CAFL entities we are exposed to certain financial risks associated with our role as a sponsor, servicing administrator, or depositor of these entities or as a result of our having sold assets directly or indirectly to these entities. For financial reporting purposes, the underlying loans owned at the consolidated Sequoia 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 are shown under Multifamily loans held-for-investment at fair value, and the underlying single-family rental loans at the consolidated CAFL entities are shown under Business purpose residential loans held-for-investment at fair value on our consolidated balance sheets. The asset-backed securities (“ABS”) issued to third parties by these entities are shown under ABS issued. In our consolidated statements of income (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 other income and expenses associated with these entities' activities.
Use of Estimates | 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.
Available-for-Sale Securities | Available-for-Sale Securities Upon adoption of ASU 2016-13, "Financial Instruments - Credit Losses" in the first quarter of 2020, we modified our policy for recording impairments on available-for-sale securities. This new guidance requires that credit impairments on our available-for-sale securities be recorded in earnings using an allowance for credit losses, with the allowance limited to the amount by which the security's fair value is less than its amortized cost basis. The allowance for credit losses is calculated using a discounted cash flow approach and is measured as the difference between the beneficial interest’s amortized cost and the estimate of cash flows expected to be collected, discounted at the effective interest rate used to accrete the beneficial interest. Any allowance for credit losses in excess of the unrealized losses on the beneficial interests are accounted for as a prospective reduction of the effective interest rate. No allowance is recorded for beneficial interests in an unrealized gain position. Favorable changes in the discounted cash flows will result in a reduction in the allowance for credit losses, if any. Any reduction in allowance for credit losses is recorded in earnings. If the allowance for credit losses has been reduced to zero, the remaining favorable changes are reflected as a prospective increase to the effective interest rate. If we intend to sell or it is more likely than not that we will be required to sell the security before it recovers in value, the entire impairment amount will be recognized in earnings with a corresponding adjustment to the security's amortized cost basis.
Goodwill | Goodwill Pursuant to our adoption of ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" in the first quarter of 2020, we modified our goodwill impairment testing policy. We first assess qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. If, based on that assessment, we believe it is more likely than not that the fair value of the reporting unit is less than its carrying value, we measure the fair value of reporting unit and record a goodwill impairment charge for the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill. Any such impairment charges would be recorded through Other expenses on our consolidated statements of income (loss).
Recent Accounting Pronouncements | Recent Accounting Pronouncements Newly Adopted Accounting Standards Updates ("ASUs") In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." This new guidance amends previous guidance by removing and modifying certain existing fair value disclosure requirements, while adding other new disclosure requirements. This new guidance is effective for fiscal years beginning after December 15, 2019. We adopted this new guidance, as required, in the first quarter of 2020, which did not have a material impact on our consolidated financial statements but impacted certain of our fair value footnote disclosures. In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This new guidance simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. This new guidance is effective for fiscal years beginning after December 15, 2019. We adopted this new guidance, as required, in the first quarter of 2020, which did not have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses." This new guidance provides a new impairment model that is based on expected losses rather than incurred losses to determine the allowance for credit losses. This new guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years beginning after December 15, 2018. In November 2018, the FASB issued ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses," which clarifies the scope of the amendments in ASU 2016-13. In April 2019, the FASB issued ASU 2019-04, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments," which is intended to clarify this guidance. In May 2019, the FASB issued ASU 2019-05, "Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief," which provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost. In November 2019, the FASB issued ASU 2019-11, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses," which is intended to clarify Codification guidance. In February 2020, the FASB issued ASU 2020-02, "Financial Instruments - Credit Losses (Topic 326) and Leases (Topic 842) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842) (SEC Update)," and in March 2020, the FASB issued ASU 2020-03, "Codification Improvements to Financial Instruments." These updates amend certain sections of the guidance. We currently have only a small balance of loans receivable that are not carried at fair value and would be subject to this new guidance for allowance for credit losses. Separately, we accounted for our available-for-sale securities under the other-than-temporary impairment ("OTTI") model for debt securities prior to the issuance of this new guidance. This new guidance requires that credit impairments on our available-for-sale securities be recorded in earnings using an allowance for credit losses, with the allowance limited to the amount by which the security's fair value is less than its amortized cost basis. Subsequent reversals in credit loss estimates are recognized in income. We adopted this guidance, as required, in the first quarter of 2020, 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. 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, 2020, we have not elected to apply the optional expedients and exceptions to any of our existing contracts, hedging relationships, or other transactions. 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. 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 the 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. 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.
Balance Sheet Netting | 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.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.
