Basis of Presentation	Note 2. Basis of Presentation The consolidated financial statements presented herein are at December 31, 2014 and 2013, and for the years ended December 31, 2014, 2013, and 2012. These consolidated financial statements have been prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States of America — as prescribed by the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) — and using the Securities and Exchange Commission’s (“SEC”) instructions to Form 10-K. *Organization* Redwood Trust, Inc. has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), beginning with its taxable year ended December 31, 1994. We generally refer, collectively, to Redwood Trust, Inc. and those of its subsidiaries that are not subject to subsidiary-level corporate income tax as “the REIT” or “our REIT.” We generally refer to subsidiaries of Redwood Trust, Inc. that are subject to subsidiary-level corporate income tax as “our operating subsidiaries” or “our taxable REIT subsidiaries” or “TRS.” Our mortgage banking activities, investments in mortgage servicing rights (“MSRs”), and certain other activities are generally carried out through our taxable REIT subsidiaries, while our portfolio of mortgage- and other real estate-related investments is primarily held at our REIT. We generally intend to retain profits generated and taxed at our taxable REIT subsidiaries, and to distribute as dividends at least 90% of the taxable income we generate at our REIT. We sponsor our Sequoia securitization program, which we use for the securitization of residential mortgage loans. References to Sequoia with respect to any time or period generally refer collectively to all the then consolidated Sequoia securitization entities for the periods presented. We have also engaged in securitization transactions in order to obtain financing for certain of our securities and commercial loans. We previously engaged in other securitization transactions through the Acacia program, which was used for the securitization of mortgage-backed securities and other types of financial assets. References to Acacia generally refer collectively to the consolidated Acacia securitization entities for the periods presented. *Principles of Consolidation* We apply FASB guidance to 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 where we maintain an ongoing involvement, as well as an entity formed in connection with a resecuritization transaction we engaged in during 2011 (“Residential Resecuritization”), and an entity formed in connection with a commercial securitization we engaged in during 2012 (“Commercial Securitization”). Prior to December 31, 2012, we consolidated the assets and liabilities of certain Acacia securitization entities. Each securitization entity is independent of Redwood and of each other and the assets and liabilities are not owned by and are not legal obligations of Redwood Trust, Inc. Our exposure to these entities is primarily through the financial interests we have retained, although we are exposed to certain financial risks associated with our role as a sponsor, manager, 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 and securities owned at the consolidated Sequoia entities, the Residential Resecuritization entity, and the Commercial Securitization entity are shown under residential and commercial loans and real estate securities on our consolidated balance sheets. The asset-backed securities (“ABS”) issued to third parties by these entities are shown under ABS issued. In our consolidated statements of income, we record interest income on the loans and securities owned at these entities and interest expense on the ABS issued by these entities. We also recorded interest income and expense on the securities and ABS at previously consolidated Acacia entities. See Note 4 for further discussion on principles of consolidation.

Organization

Redwood Trust, Inc. has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), beginning with its taxable year ended December 31, 1994. We generally refer, collectively, to Redwood Trust, Inc. and those of its subsidiaries that are not subject to subsidiary-level corporate income tax as “the REIT” or “our REIT.” We generally refer to subsidiaries of Redwood Trust, Inc. that are subject to subsidiary-level corporate income tax as “our operating subsidiaries” or “our taxable REIT subsidiaries” or “TRS.” Our mortgage banking activities, investments in mortgage servicing rights (“MSRs”), and certain other activities are generally carried out through our taxable REIT subsidiaries, while our portfolio of mortgage- and other real estate-related investments is primarily held at our REIT. We generally intend to retain profits generated and taxed at our taxable REIT subsidiaries, and to distribute as dividends at least 90% of the taxable income we generate at our REIT.

We sponsor our Sequoia securitization program, which we use for the securitization of residential mortgage loans. References to Sequoia with respect to any time or period generally refer collectively to all the then consolidated Sequoia securitization entities for the periods presented. We have also engaged in securitization transactions in order to obtain financing for certain of our securities and commercial loans.

Principles of Consolidation

We apply FASB guidance to 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 where we maintain an ongoing involvement, as well as an entity formed in connection with a resecuritization transaction we engaged in during 2011 (“Residential Resecuritization”), and an entity formed in connection with a commercial securitization we engaged in during 2012 (“Commercial Securitization”). Prior to December 31, 2012, we consolidated the assets and liabilities of certain Acacia securitization entities. Each securitization entity is independent of Redwood and of each other and the assets and liabilities are not owned by and are not legal obligations of Redwood Trust, Inc. Our exposure to these entities is primarily through the financial interests we have retained, although we are exposed to certain financial risks associated with our role as a sponsor, manager, 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 and securities owned at the consolidated Sequoia entities, the Residential Resecuritization entity, and the Commercial Securitization entity are shown under residential and commercial loans and real estate securities on our consolidated balance sheets. The asset-backed securities (“ABS”) issued to third parties by these entities are shown under ABS issued. In our consolidated statements of income, we record interest income on the loans and securities owned at these entities and interest expense on the ABS issued by these entities. We also recorded interest income and expense on the securities and ABS at previously consolidated Acacia entities.
