Net loss per share attributable to common stockholders

Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The Company considers its redeemable convertible preferred stock to be participating securities as the holders of redeemable convertible preferred stock are entitled to receive noncumulative dividends in the event that a dividend is paid on common stock. The holders of redeemable convertible preferred stock and the holders of non-vested restricted stock do not have a contractual obligation to share in the losses of the Company. Basic net loss attributable to common stockholders per share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding less shares subject to repurchase. Diluted net loss per share attributable to common stockholders adjusts the basic net loss per share attributable to common stockholders and the weighted-average number of shares of common stock outstanding for the potentially dilutive impact of stock options and restricted stock, using the treasury stock method, and convertible preferred stock using the as-if-converted method.

The following table sets forth the computation of the Company’s basic and diluted net loss per share attributable to common stockholders:

The following potentially dilutive shares were excluded from the computation of diluted net loss per share for the periods presented because including them would have been antidilutive:
