Net Loss Per Share Available to Common Stockholders

11. Net Loss Per Share Available to Common Stockholders

Basic net loss per share available to common stockholders is calculated by dividing the net loss available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The weighted-average number of shares of common stock used to calculate the Company’s basic net loss per share available to common stockholders excludes those shares subject to repurchase related to unvested common shares, stock options that were exercised prior to vesting, restricted stock issued and RSUs settled for shares of common stock, as these shares are not deemed to be outstanding for accounting purposes until they vest. The diluted net loss per share of common stock is computed by dividing the net loss using the weighted-average number of shares of common stock, excluding common stock subject to repurchase, and, if dilutive, potential shares of common stock outstanding during the period. Potential shares of common stock consist of common stock subject to repurchase, stock options to purchase common stock, restricted common stock issued and RSUs settled for shares of common stock.

The following table presents the calculation of basic and diluted net loss per share:

The following table presents the potential shares of common stock outstanding that were excluded from the computation of diluted net loss per share available to common stockholders for the periods presented because including them would have been anti-dilutive:
