(5) Basic and Diluted Average Shares

 

A reconciliation of basic and diluted average common shares for the three months ended March 31, 2013 and 2012 is as follows:

 

    For the Three Months Ended  
    March 31,  
    2013     2012  
             
Basic weighted average shares     12,175,584       12,174,689  
Effect of potential dilutive securities:                
Stock options     137,464       369,454  
Diluted weighted average shares     12,313,048       12,544,143  

 

For the three months ended March 31, 2013 and 2012, approximately 5,030,000 and 5,000,000 common stock options, respectively, were not added to the diluted average shares because inclusion of such shares would be antidilutive.
