(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 RSUs outstanding from our equity incentive plans as discussed in note 2.

For both 13 week periods ended September 26, 2017 and September 27, 2016, 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 26, 2017 and September 27, 2016, there were 7,960 and six shares of nonvested stock, respectively, that had an anti-dilutive effect. For all periods presented, there were no outstanding options that had an anti-dilutive effect.

PSUs are not included in the diluted earnings per share calculation until the performance-based criteria have been met. See note 2 for further discussion of PSUs.

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:
