(8) Earnings Per Share

The share and net income per share data for all periods presented are based on the historical weighted-average shares outstanding. The diluted earnings per share calculations show the effect of the weighted-average stock options and restricted stock units outstanding from our equity incentive plans. Performance stock units are not included in the diluted earnings per share calculation until the performance-based criteria have been met.

For the 13 week periods ended June 26, 2018 and June 27, 2017, there were 1,231 and 17,691 shares of nonvested stock, respectively, that were outstanding but not included in the computation of diluted earnings per share because their inclusion would have had an anti-dilutive effect. For the 26 week periods ended June 26, 2018 and June 27, 2017, there were 7,937 and 31,136 shares of nonvested stock, respectively, that were not included because they would have had an anti-dilutive effect.
