Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Principles of Consolidation | 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 As of December 31, 2017, we consolidated certain Legacy Sequoia and our Sequoia Choice 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 we are exposed to certain financial risks associated with our role as a sponsor, servicing administrator, or depositor of these entities or as a result of our having sold assets directly or indirectly to these entities. At December 31, 2017, the estimated fair value of our investments in the consolidated Legacy Sequoia and Sequoia Choice entities was $14 million and $78 million, respectively. The following table presents a summary of the assets and liabilities of these VIEs. Table 4.1 – Assets and Liabilities of Consolidated VIEs

We consolidate the assets and liabilities of certain Sequoia 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 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; 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 entities in accordance with GAAP. Analysis of Unconsolidated VIEs with Continuing Involvement Since 2012, we have transferred residential loans to 36 Sequoia securitization entities sponsored by us and accounted for these transfers as sales for financial reporting purposes, in accordance with ASC 860. We also determined we were not the primary beneficiary of these VIEs as we lacked the power to direct the activities that will have the most significant economic impact on the entities. For 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 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 years ended December 31, 2017 and 2016, we transferred residential loans to seven and three Sequoia securitization entities sponsored by us, respectively, and accounted for these transfers as sales for financial reporting purposes. The following table presents information related to securitization transactions that occurred during the years ended December 31, 2017 and 2016.

The following table presents the key weighted average assumptions used to measure MSRs and securities retained at the date of securitization for securitizations completed during 2017 and 2016. Table 4.4 – Assumptions Related to Assets Retained from Unconsolidated VIEs Sponsored by Redwood

The following table presents additional information at December 31, 2017 and December 31, 2016, related to unconsolidated VIEs sponsored by Redwood and accounted for as sales since 2012. Table 4.5 – Unconsolidated VIEs Sponsored by Redwood

(1) | Maximum loss exposure from our involvement with unconsolidated VIEs pertains to the carrying value of our securities and MSRs retained from these VIEs and represents estimated losses that would be incurred under severe, hypothetical circumstances, such as if the value of our interests and any associated collateral declines to zero. This does not include, for example, any potential exposure to representation and warranty claims associated with our initial transfer of loans into a securitization.

Analysis of Third-Party VIEs Third-party VIEs are securitization entities in which we maintain an economic interest, but do not sponsor. Our economic interest may include several securities from the same third-party VIE, and in those cases, the analysis is performed in consideration of all of our interests. The following table presents a summary of our interests in third-party VIEs at December 31, 2017, grouped by security type. Table 4.7 – Third-Party Sponsored VIE Summary
(Dollars in Thousands) |  | December 31, 2017
Mortgage-Backed Securities |  |
Senior |  | $ | 177,191 |
Re-REMIC |  | 38,875 |
Subordinate |  | 939,763 |
Total Investments in Third-Party Sponsored VIEs |  | $ | 1,155,829 |
We determined that we are not the primary beneficiary of any third-party VIEs, as we do not have the required power to direct the activities that most significantly impact the economic performance of these entities. Specifically, we do not service or manage these entities or otherwise solely hold decision making powers that are significant. As a result of this assessment, we do not consolidate any of the underlying assets and liabilities of these third-party VIEs – we only account for our specific interests in them. Our assessments of whether we are required to consolidate a VIE may change in subsequent reporting periods based upon changing facts and circumstances pertaining to each VIE. Any related accounting changes could result in a material impact to our financial statements.
