Earnings Per Share [Abstract]  
Net Income Per Share
Net Income Per Share
Basic net income per share is computed using the weighted-average number of common shares outstanding for the period. Diluted net income per share is computed by adjusting the weighted-average number of common shares outstanding for the effect of dilutive potential common shares outstanding during the period. Potential common shares included in the diluted calculation consist of incremental shares issuable upon the exercise of outstanding stock options calculated using the treasury stock method.
The following table sets forth the calculation of basic and diluted net income per share (in thousands, except per share amounts):
