SHARE-BASED PAYMENTS	7. SHARE-BASED PAYMENTS For the third quarter and first three quarters of fiscal 2021, we recognized total stock-based compensation expense (including restricted stock units, cash-settled restricted stock units, performance shares, and performance-based restricted stock units) of $10.4 million and $42.4 million, respectively. For the third quarter and first three quarters of fiscal 2020, we recognized total stock-based compensation expense of $9.3 million and $33.8 million, respectively. In the first three quarters of fiscal 2021, we granted 0.9 million restricted stock units at a weighted average grant date price of $36.70 and 0.5 million performance shares at a weighted average grant date price of $36.82. Performance shares are granted to selected executives and other key employees with vesting contingent upon meeting various Company-wide performance goals. The performance goals for the three-year performance periods ending in fiscal 2021 (the "2021 performance period") and fiscal 2022 ("2022 performance period") are based on our diluted earnings per share ("EPS") compound annual growth rate ("CAGR"), subject to certain adjustments, measured over the defined performance periods. The performance goal for one-third of the target number of performance shares for the three-year performance period ending in fiscal 2023 (the "2023 performance period") is based on our fiscal 2021 diluted EPS CAGR, subject to certain adjustments. The performance goal for the final two-thirds of the target number of performance shares granted for the 2023 performance period is expected to be set following the end of fiscal 2021. For each of the 2021 performance period, 2022 performance period, and 2023 performance period, the awards actually earned will range from zero to two hundred percent of the targeted number of performance shares for such performance period. Dividend equivalents are paid on the portion of performance shares actually earned at our regular dividend rate in additional shares of common stock. Awards, if earned, will be paid in shares of our common stock. Subject to limited exceptions set forth in our performance share plan, any shares earned will be distributed after the end of the performance period, and only if the participant continues to be employed with the Company through the date of distribution. For awards where performance against the performance target has not been certified, the value of the performance shares is adjusted based upon the market price of our common stock and current forecasted performance against the performance targets at the end of each reporting period and amortized as compensation expense over the vesting period. Forfeitures are accounted for as they occur.
