Weighted Average Shares Outstanding and Net Income (Loss) Per Share
Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common shares and dilutive potential common shares outstanding during the period. Potential common shares include stock options and restricted stock units. The following table presents a reconciliation of the weighted average shares outstanding used in calculating basic and diluted net income (loss) per share as well as the calculation of basic and diluted net income (loss) per share:

1Due to the net loss for the six months ended June 30, 2014, restricted stock units and common stock options representing approximately 746,000 shares have been excluded from the number of shares used in calculating diluted net loss per share, as their inclusion would be antidilutive.
