Earnings Per Share [Abstract] |
Earnings Per Share | EARNINGS PER SHARE Basic earnings per share are based on the weighted average number of common shares outstanding without consideration of potential common stock. In addition, diluted earnings per share include the dilutive effect of potential common stock consisting of stock options, restricted stock units and performance stock units, provided that the inclusion of such securities is not antidilutive. In periods with a net loss, stock options and restricted stock units are not included in the computation of diluted loss per share as the impact would be anti-dilutive. The following table reconciles basic to diluted weighted-average shares outstanding for the three and six months ended November 30, 2015 and 2014 (in thousands):
