(a)

Potentially dilutive shares of common stock from employee incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options and the assumed vesting of outstanding restricted stock units and performance awards. As of February 28, 2021, we did not have any stock-based awards that were antidilutive. As of February 23, 2020, an insignificant number of stock-based awards were excluded from the computation of diluted earnings per share because they would be antidilutive.
