NET (LOSS) INCOME PER SHARE

Basic net (loss) income per share is computed using the weighted-average number of outstanding shares of common stock during the period. Diluted net (loss) income per share is computed using the weighted-average number of outstanding shares of common stock and, when dilutive, potential shares of common stock outstanding during the period. Potential common shares consist of the incremental shares of common stock issuable upon the exercise of stock options, shares issuable upon the vesting of RSUs and, to a lesser extent, purchase rights related to the ESPP.
