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 the impact is anti-dilutive, these shares were excluded from the calculations of diluted net income per share.

The calculation of basic and diluted net income per share is as follows:
