(5) | Earnings Per Share
Earnings per common share attributable to Landstar System, Inc. and subsidiary 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 attributable to Landstar System, Inc. and subsidiary 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 2020 and 2019 twenty-six-week and thirteen-week periods , the future compensation cost attributable to shares of non-vested restricted stock exceeded the 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 27, 2020 and June 29, 2019, no options outstanding to purchase shares of common stock were antidilutive. Outstanding RSUs were excluded from the calculation of diluted earnings per share attributable to Landstar System, Inc. and subsidiary for all periods because the performance metric requirements or market condition for vesting had not been satisfied.
