3. Net Loss Per Share

​

Basic net loss per common share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period without consideration of common stock equivalents. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock equivalents outstanding for the period. Potentially dilutive securities consisting of stock issuable under options, ESPP and RSUs and are not included in the per common share calculation in periods when the inclusion of such shares would have an anti-dilutive effect.
