Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is determined based on the dilutive effect of share-based awards using the treasury stock method.

Share-based awards that were outstanding at the end of the respective periods, but were not included in the computation of diluted earnings per share because the effect of exercising such awards would be antidilutive, were

1.9 million and 1.6 million in the 2016 and 2015 13-week periods, respectively, and were 1.6 million and 1.2 million in the 2016 and 2015 39-week periods, respectively.
