(4) | Earnings Per Share
Earnings per common share are based on the weighted average number of shares outstanding, including outstanding non-vested restricted stock and outstanding Deferred Stock Units. Diluted earnings per share are based on the weighted average number of common shares and Deferred Stock Units outstanding plus the incremental shares that would have been outstanding upon the assumed exercise of all dilutive stock options. During the 2021 and 2020 twenty-six-week and thirteen-week periods, in reference to the determination of diluted earnings per share, the future compensation cost attributable to outstanding shares of non-vested restricted stock exceeded the impact of incremental shares that would have been outstanding upon the assumed exercise of all dilutive stock options. For each of the twenty-six-week periods ended June 26, 2021 and June 27, 2020, no options outstanding to purchase shares of common stock were antidilutive. Outstanding RSUs were excluded from the calculation of diluted earnings per share for all periods because the performance metric requirements or market condition for vesting had not been satisfied.
