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:


	Three months ended
(amounts in thousands)	October 29, 2017	October 30, 2016
Weighted average common shares outstanding, basic	12,440	12,308
Dilutive effect of stock-based compensation	140	199
Weighted average common shares outstanding, diluted	12,580	12,507

All options to purchase shares of common stock were included in the computation of diluted net income for the three months ended October 29, 2017 and October 30, 2016, as the exercise price of the options was less than the average market price of the common shares.


	Six months ended
(amounts in thousands)	October 29, 2017	October 30, 2016
Weighted average common shares outstanding, basic	12,420	12,297
Dilutive effect of stock-based compensation	193	198
Weighted average common shares outstanding, diluted	12,613	12,495

All options to purchase shares of common stock were included in the computation of diluted net income for the six months ended October 29, 2017 and October 30, 2016, as the exercise price of the options was less than the average market price of the common shares.
