(1) For each year shown, the CEO was David P. Singelyn. For 2022 and 2021, the other NEOs were Jack Corrigan, Bryan Smith, Christopher C. Lau and Sara H. Vogt-Lowell, and for 2020, the other NEOs were Jack Corrigan, Bryan Smith, Christopher C. Lau, Sara H. Vogt-Lowell and Stephanie G. Heim. (2) The values reflected in this column reflect the “Total” compensation set forth in the Summary Compensation Table (“SCT”) on page 51. See the footnotes to the SCT for further detail regarding the amounts in this column. (3) Compensation actually paid (“CAP”) is defined by the SEC and is computed in accordance with SEC rules by subtracting the amounts in the “Stock Awards” and “Option Awards” columns of the SCT for each year from the “Total” column of the SCT and then: (i) adding the fair value as of the end of the reported year of all awards granted during the reporting year that are outstanding and unvested as of the end of the reporting year; (ii) adding the amount equal to the change as of the end of the reporting year (from the end of the prior year) in fair value (whether positive or negative) of any awards granted in any prior year that are outstanding and unvested as of the end of the reporting year; (iii) adding the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value (whether positive or negative) of any awards granted in any prior year for which all applicable vesting conditions were satisfied at the end of or during the reporting year; (iv) subtracting for any awards granted in any prior year that are forfeited during the reporting year, the amount equal to the fair value at the end of the prior year; and (v) adding the value of any dividends (or dividend equivalents) paid in the reporting year on unvested equity awards and the value of accrued dividends (or dividend equivalents) paid on performance awards that vested in the reporting year. The following tables reflect the adjustments made to SCT total compensation to compute CAP for our CEO and average CAP for our other NEOs. CEO
