Earnings Per Share [Abstract]  
Earnings Per Share
EARNINGS PER SHARE
Basic earnings per share (EPS) is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS reflects potential dilution that could occur if securities to issue common stock were exercised or converted into common stock. Diluted EPS includes the dilutive effect of share-based compensation outstanding after application of the treasury stock method.
