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 31, 2011
    
August 1, 2010
  
Weighted average common shares outstanding, basic
     13,061       12,870  
Dilutive effect of stock-based compensation
     144       329  
Weighted average common shares outstanding, diluted
     13,205       13,199  

Options to purchase 24,750 shares of common stock were not included in the computation of diluted net income per share for the three months ended July 31, 2011, as the exercise price of the options was greater than the average market price of the common shares. All options of common stock were included in the computation of diluted net income for the three months ending August 1, 2010, as the exercise price of the options was less than the average market price of the common shares.
 
The computations of basic net income per share did not include 185,000 and 195,000 shares of time vested restricted common stock as these shares were unvested for the three months ending July 31, 2011 and August 1, 2010, respectively.
