10. 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. 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.
