Earnings Per Share [Abstract]  
Earnings (Loss) Per Share
Earnings (Loss) Per Share

We compute basic earnings (loss) per share using the weighted average number of common shares outstanding. We compute diluted earnings (loss) per share using the weighted average number of common shares outstanding plus the effect of outstanding dilutive stock options, restricted stock units and deferred stock units, using the treasury stock method. The following table sets forth the calculation of basic and diluted earnings per share from continuing operations (in thousands, expect per share data):

We excluded stock awards representing approximately 494,000 shares, 2,058,000 shares, and 2,552,000 shares of common stock from the calculation of diluted earnings per share in the fiscal years ended November 30, 2017, 2016 and 2015, respectively, because these awards were anti-dilutive.
