Earnings Per Share
Earnings Per Share

We compute basic earnings per share using the weighted average number of common shares outstanding. We compute diluted earnings 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 on an interim basis (in thousands, expect per share data):

We excluded stock awards representing approximately 1,393,000 shares and 4,319,000 shares of common stock from the calculation of diluted earnings per share in the three months ended February 28, 2013 and February 29, 2012, respectively, because these awards were anti-dilutive.
