(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 both 13 week periods ended September 25, 2018 and September 26, 2017, there were no shares of nonvested stock 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 39 week periods ended September 25, 2018 and September 26, 2017, there were 220 and 7,960 shares of nonvested stock, respectively, that were not included because they would have had an anti-dilutive effect.

The following table sets forth the calculation of earnings per share and weighted-average shares outstanding (in thousands) as presented in the accompanying unaudited condensed consolidated statements of income and comprehensive income:
