Net Income Per Share
11.  Net Income Per Share

Basic net income per share is computed using the weighted-average number of shares outstanding during the period.  Diluted net income per share uses the weighted-average number of shares outstanding during the period plus the dilutive effect of stock-based compensation calculated using the treasury stock method.  Weighted average shares used in the computation of basic and diluted net income per share follows:

All options to purchase shares of common stock were included in the computation of diluted net income for the three months ended July 31, 2016 and August 2, 2015, as the exercise price of the options was less than the average market price of the common shares.
