Earnings Per Share [Abstract]  
Net Income Per Share
Net Income Per Share

Basic net income per share is computed by dividing the net income for the period by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing the net income 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 Employee Stock Purchase Plan (the "ESPP"), which are reflected in diluted net income per share by application of the treasury stock method.
Net income per share for the three and nine months ended October 1, 2017 and October 2, 2016 are as follows:
