_______________ (a) The fair values of the equity awards were calculated using valuation assumptions that materially differ from those disclosed at the time of grant, including: (1) the fair value of RSU awards was calculated using the closing price of our common stock as of the last day of the applicable year or on the date of vesting, as applicable; (2) the fair value of CFCF PSU awards was estimated using the closing stock price of our common stock as of the last day of the applicable year and adjusted for management's estimate of performance; (3) the fair value of RTSR PSU awards was estimated using the Monte Carlo Simulation method (which reflects for each particular award and valuation date adjustments for: estimates of performance, expected volatility, risk-free interest rate, correlation coefficient, and dividend yield); and (4) the fair value of options was estimated using the Black-Scholes option-pricing model (which reflects for each particular award and valuation date: adjustments for expected volatility, risk-free interest rate, dividend yield, expected term - calculated using the simplified method, and stock price). Declining stock price served as the primary driver of change in the fair value of options, partially offset by an increase in volatility - in particular for options granted prior to 2019, none of which were in-the-money as of any valuation date applicable to this table. (4)Peer group is the S&P Home Builders Select Industry index, or XHB Index (which includes a diversified group of holdings representing home building, building products, home furnishings and home appliances). The XHB Index is the published industry or line-of-business index utilized in the Company's Annual Report on Form 10-K for the year ended December 31, 2022. (5)Represents the amount of net income (loss) reflected in our audited financial statements for each applicable fiscal year. (6)Operating EBITDA is our primary non-GAAP measure. See Annex A for a definition of Operating EBITDA, an explanation of why we believe this non-GAAP measure is useful to investors and the limitations of this measure as an analytical tool.
