(12) 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 restricted stock units and stock options outstanding from our equity incentive plans. Performance stock units ("PSUs") are not included in the diluted earnings per share calculation until the performance-based criteria have been met. See note 14 for further discussion of our equity incentive plans.

For the year ended December 25, 2018, 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 years ended December 26, 2017 and December 27, 2016, there were 2,082 and two shares of nonvested stock, respectively, that were not included because they would have had an anti-dilutive effect.
