Net Income Per Share
Net Income Per Share

Basic net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. Potentially dilutive common shares include common shares issuable upon exercise of stock options, vesting of restricted stock awards, and issuances of shares under the ESPP, which are reflected in diluted net income per share by application of the treasury stock method. Potentially dilutive common shares are excluded from the computation of diluted net income (loss) per share when their effect is anti-dilutive.
Net income (loss) per share for the three and six months ended July 1, 2018 and July 2, 2017 are as follows:
