The dollar amounts do not reflect the actual amount of compensation earned or paid during the applicable year. In accordance with the requirement of Item 402(v) of Regulation S-K, “Compensation Actually Paid” for 2023 is calculated by making the following adjustments from the Summary Compensation Table totals as follows:

(*) Fair value of outstanding and unvested equity awards were determined using valuation assumptions, methodologies and market condition inputs (including, for example, risk-free interest rates and the following metrics related to Redwood common stock: market value, volatility, and dividend yield) that are generally consistent with those used to estimate fair value at grant date in accordance with ASC Topic 718. For awards subject to financial performance-based vesting conditions (e.g., performance stock units), fair values reflect an estimate of the probable outcome of the financial performance-based vesting conditions updated as of each measurement date. See “Equity Compensation Plans” in Note 19 to Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for 2023, which sets forth assumptions made in valuing awards subject to financial performance-based vesting conditions at grant date and at measurement dates subsequent to grant date during the corresponding vesting periods. Value of equity awards at vesting is determined by the closing market price of the number of shares of common stock that vest on the applicable vesting date. (†) Amounts represent changes in value from beginning of year to end of year or vesting date of individual awards. (©) Table does not include reconciling line items for (i) changes in pension benefits, (ii) awards that were granted and vested in the same year, or (iii) awards granted during a prior period that were forfeited during the Covered Year, as these items were not applicable for Redwood in 2023. |  |  |
