(a) Each of our performance-based restricted share represents a contingent right to receive one share of the Company's common stock if vesting is satisfied at the end of the three-year performance period. Our performance stock award plans provide that any performance shares earned in excess of the target number of performance shares issued may be settled in cash or additional shares at the discretion of the Compensation Committee. In November 2020, we issued 60,930 shares earned above target level based on the performance level achieved under the fiscal 2018 performance-based award plan.
