Net income (loss) per share attributable to common stockholders

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.

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:
