For the three months ended March 31, 2011 and 2012, outstanding stock options were the only potentially dilutive securities.

 

The reconciliation from basic to diluted weighted average common shares outstanding is as follows (in thousands):

Diluted weighted average common shares outstanding

The above calculations for the three months ended March 31, 2011 and 2012 do not include 195,000 and 324,000 shares, respectively, related to certain stock options because the effects of such were anti-dilutive.
