Earnings Per Share [Abstract] |
Net Income Per Share |
| Net Income Per Share
Basic net income per share is computed by dividing net income for the period by the weighted average number of shares outstanding during the period, less shares subject to repurchase. Diluted net income per share is computed by dividing net income for the period by the weighted average number of shares, less shares subject to repurchase, plus, if dilutive, potential common stock outstanding during the period. Potential common stock includes the effect of outstanding dilutive stock options, restricted stock awards and restricted stock units computed using the treasury stock method. Since their impact is anti-dilutive, we excluded 426,974 and 364,450 shares, respectively, from the calculations of diluted net income per share for the three and nine months ended September 30, 2014 and 465,301 and 1,178,755 shares, respectively, from the same calculations for the three and nine months ended September 30, 2013. The calculation of basic and diluted net income per share is as follows (in thousands, except per share amounts):
