Earnings Per Share [Abstract]  
EARNINGS PER SHARE EARNINGS PER SHARE
Basic EPS is computed based on the weighted average shares of common stock outstanding during the period. Diluted EPS is computed based on those shares used in the basic EPS computation, plus potentially dilutive shares issuable under our equity-based compensation plans using the treasury stock method. Shares that are potentially anti-dilutive are excluded.
The following table presents the computation of our basic and diluted EPS attributable to our common stock:
