    Three months ended March 31,  
    2012     2011  
    (in thousands, except per share amounts)  
             
Net income  attributable to Innodata Isogen, Inc. and Subsidiaries   $ 3,432     $ 15  
                 
Weighted average common shares outstanding     24,459       25,155  
Dilutive effect of outstanding stock awards     1,515       259  
Adjusted for dilution computation     25,974       25,414  

 

Basic income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted income per share is computed by considering the impact of the potential issuance of common shares, using the treasury stock method, on the weighted average number of shares outstanding. For those securities that are not convertible into a class of common stock, the “two class” method of computing income per share is used.

 

Options to purchase 0.1 million shares of common stock and 1.3 million shares of common stock as of March 31, 2012 and 2011, respectively, were outstanding but not included in the computation of diluted income per share, because the options exercise price was greater than the average market price of the common shares, and therefore, the effect would have been antidilutive.
