Earnings Per Share [Abstract]  
EARNINGS PER SHARE EARNINGS PER SHARE
Basic earnings per share is computed using the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per share is computed using the weighted-average number of common shares outstanding during the applicable period, plus the dilutive effect of outstanding stock options and RSUs, using the treasury stock method. In periods of loss, all stock options and RSUs are excluded, as their inclusion would be anti-dilutive.
The calculation of the basic and diluted earnings per share was:
