Net Earnings Per Share [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Net Earnings Per Share | Basic net earnings per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net earnings per share is computed using the weighted-average number of common shares outstanding plus dilutive potential common shares outstanding during the period.
Employee stock options, nonvested shares and similar equity instruments granted by the Company are treated as potential common share equivalents outstanding in computing diluted net earnings per share. The Company’s diluted common shares outstanding reported in each period includes the dilutive effect of restricted stock units, in-the-money options, and performance stock units for which threshold performance conditions have been satisfied and is calculated based on the average share price for each fiscal period using the treasury stock method.
The following table shows the securities excluded from the computation of earnings per share since their inclusion would have been anti-dilutive:
Performance stock units are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied. At May 31, 2012, the threshold performance conditions for the November 12, 2009 grants had been satisfied resulting in the inclusion of 37,746 performance stock units in the calculation of diluted net earnings per share. At May 31, 2012 and 2011, there were 43,388 and 98,625, respectively, of performance stock units excluded from the calculation of diluted net earnings per share because the threshold performance conditions had not been satisfied. |
