Basic net income per share is computed using the weighted average number of shares of common stock outstanding for the period, excluding unvested RSUs and stock options. Diluted net income per share is based upon the weighted average shares of common stock outstanding for the period plus dilutive potential shares of common stock, including unvested RSUs and stock options using the treasury stock method.
