(1)
These amounts represent the fair value as of the indicated fiscal year-end of the outstanding and unvested equity awards granted during such fiscal year, calculated in accordance with the methodology used for financial reporting purposes. The fair value differs from the value in the SCT because for purposes of CAP the fair value for equity awards granted in the current year is determined as of the last day of the applicable year. Fair values in the SCT are determined as of the grant date.
​
(2)
These amounts represent the change in fair value during the indicated fiscal year of each equity award that was granted in a prior fiscal year and that remained outstanding and unvested as of the last day of the indicated fiscal year, calculated in accordance with the methodology used for financial reporting purposes and, for awards subject to performance-based vesting conditions, based on an estimate of the probable outcome of such performance-based vesting conditions as of the last day of the fiscal year.
​
(3)
These amounts represent the change in fair value, measured from the prior fiscal year-end to the vesting date, of each equity award that was granted in a prior fiscal year and which vested during the indicated fiscal year, calculated in accordance with the methodology used for financial reporting purposes.
