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 well 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 securities. Our aggregation, origination and investment activities have evolved to incorporate a diverse mix of residential, business purpose and multifamily assets. 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 Mortgage Banking, Business Purpose Mortgage Banking, and Investment Portfolio.</span></div><div style="margin-top:9pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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. </span></div><div style="margin-top:12pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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.

CY2022	us-gaap	Use Of Estimates UseOfEstimates	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.
