Earnings Per Share [Abstract]  
EARNINGS PER SHARE
EARNINGS PER SHARE
Basic earnings per share is computed by dividing income available to common stockholders by the weighted-average number of shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if common stock equivalents were exercised, and the impact of restricted stock awards expected to vest, which would then share in the earnings of the Company. 
The difference between basic and diluted weighted-average shares results from the assumed exercise of outstanding stock options and grants of restricted stock, calculated using the treasury stock method. The following presents the number of incremental weighted-average shares used in computing diluted per share amounts for the three and nine months ended May 31, 2012 and 2011:
