Earnings Per Share [Abstract]  
Net Income (Loss) Per Share
Net Income (Loss) Per Share
Basic net income (loss) per share is computed by dividing the net income (loss) available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted net income (loss) per share available to common stockholders is computed by using the weighted-average number of common shares outstanding, including potential dilutive common shares assuming the dilutive effect of outstanding stock options and RSUs using the treasury stock method. For periods in which there was a net loss, the number of shares used in the computation of diluted net loss per share was the same as that used for the computation of basic net loss per share, as the inclusion of dilutive common shares would be anti-dilutive.
The following table presents the calculation of basic and diluted net income (loss) per share (in thousands, except per share amounts):
