| 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 1,178,755 and 2,067,273 shares from the calculations of diluted net income per share for the nine months ended September 30, 2013 and 2012, respectively. The calculation of basic and diluted net income per share is as follows (in thousands, except per share amounts):
