Net Income Per Share
12.  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)
  
July 28, 2013
  
July 29, 2012
Weighted average common shares outstanding, basic
     12,148       12,551  
Dilutive effect of stock-based compensation
     218       160  
Weighted average common shares outstanding, diluted
     12,366       12,711  
 
All options to purchase shares of common stock were included in the computation of diluted net income for the three months ended July 28, 2013 and July 29, 2012, as the exercise price of the options was less that the average market price of the common shares.
 
The computations of basic net income per share did not include 61,667 and 123,335 shares of time vested restricted common stock as these shares were unvested for the three months ending July 28, 2013 and July 29, 2012, respectively.
