Basic net income (loss) per share attributable to common stockholders is computed using the weighted-average number of outstanding shares of common stock during the period. Diluted net income (loss) per share attributable to common stockholders is computed using the weighted-average number of outstanding shares of common stock and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities include stock options, RSUs (including PRSUs) and, to a lesser extent, ESPP shares. If dilutive, such potentially dilutive securities are reflected in net income (loss) per share attributable to common stockholders using the treasury stock method.

The following tables present the calculation of basic and diluted net income per share attributable to common stockholders for the periods presented (in thousands, except per share data):

The following stock-based instruments were excluded from the calculation of diluted net income per share attributable to common stockholders because their effect would have been anti-dilutive for the periods presented (in thousands):
