4. Basic and Diluted Net Income Per Share

 

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common and dilutive common equivalent shares outstanding during the period. The number of dilutive common equivalent shares outstanding during the period has been determined in accordance with the treasury-stock method. Common equivalent shares consist of common stock issuable upon the exercise of outstanding options and common stock issuable upon the vesting of outstanding, unvested SUAs.

 

Basic and diluted weighted average common shares outstanding are as follows:

 

    Three Months Ended     Six Months Ended  
    June 30,     June 30,     June 30,     June 30,  
    2012     2011     2012     2011  
    (in thousands)  
                         
Weighted average common shares     5,260       5,233       5,248       5,223  
Common equivalent shares     6       9       7       9  
Weighted average common shares outstanding, assuming dilution     5,266       5,242       5,255       5,232  

 

For the three months ended June 30, 2012 and 2011, options to purchase 192 thousand and 262 thousand common shares, respectively, were outstanding but not included in the diluted weighted average common share calculation as the effect would have been antidilutive. The amounts for the six month period ended June 30, 2012 and 2011 were 199 thousand and 267 thousand common shares, respectively.
