| Adjustment To PEO Compensation, Footnote | Compensation actually paid (“CAP”) is defined by the SEC and is computed by subtracting the amounts in the “Stock Awards” column 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, for awards that are granted and vest in the reporting year, the fair value as of the vesting date; (iv) 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; and (v) 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.
