Net income (loss) per share attributable to common stockholders

Basic and diluted net income (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 were entitled to receive noncumulative dividends in the event that a dividend was paid on common stock. Upon the closing of the IPO, all outstanding shares of the Company’s redeemable convertible preferred stock automatically converted into 32,482,590 shares of common stock on a one-for-one basis.

Basic net income (loss) attributable to common stockholders per share is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding less shares subject to repurchase. Diluted net income (loss) per share attributable to common stockholders adjusts the basic net income (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 RSUs, 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 income (loss) per share attributable to common stockholders:

The following potentially dilutive shares were excluded from the computation of diluted net income (loss) per share attributable to common stockholders because including them would have been antidilutive:
