Net Income Per Share

10.           Net Income Per Share

Basic net income per share attributable to common stockholders is calculated by dividing the net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period.

Diluted net income per share attributable to common stockholders is computed by dividing the diluted net income attributable to common stockholders by the weighted average number of common shares outstanding for the period, including potential dilutive common shares assuming dilutive effect of outstanding common stock options, restricted stock units, and common stock warrants. In periods when the Company has incurred a net loss, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders because dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

A reconciliation of net income available to common stockholders and the number of shares in the calculation of basic and diluted net income per share follows (in thousands, except share and per share amounts):
