8. Net Loss Per Share

Basic net loss per share is calculated by dividing the net income or loss available to common stockholders by the weighted average number of common shares outstanding for the period, including contingently redeemable common stock recorded outside of stockholder’s equity. Diluted net loss per share attributable to common stockholders is calculated by dividing net loss available to common stockholders by the diluted weighted average number of common shares outstanding for the period, including contingently redeemable common stock. Diluted net loss from continuing operations per share attributable to common stockholders is calculated by dividing income from continuing operations available to common stockholders by the diluted weighted average number of common shares outstanding for the period, including contingently redeemable common stock. Diluted net loss from discontinued operations per share attributable to common stockholders is calculated by dividing loss from discontinued operations available to common stockholders by the diluted weighted average number of common shares outstanding for the period, including contingently redeemable common stock.
