Net Income Per Share

Net Income Per Share

    Basic net income per share is computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed using the weighted-average number of shares of common stock outstanding during the period, including potential common shares assuming the dilutive effect of outstanding stock options, restricted stock units, and the employee stock purchase plan using the treasury stock method. Potential common shares whose effect would have been antidilutive are excluded from the computation of diluted net income per share. The following table sets forth the computation of our basic and diluted net income per share (in millions, except per share amounts):
