Earnings Per Share [Abstract]  
Earnings Per Share
EARNINGS PER SHARE
 
Basic earnings per share is computed based on the weighted average number of shares outstanding during the period, excluding unvested restricted stock. Diluted earnings per share is computed based on the weighted average number of shares outstanding during the period increased by the effect of dilutive employee stock awards, including stock options, restricted stock awards and stock purchase plan contracts, using the treasury stock method.
 
The following table presents information necessary to calculate basic and diluted earnings per share (in thousands, except per share data):
