BASIC AND DILUTED INCOME PER SHARE
 
Basic income per share is computed by dividing income by the weighted average number of common shares outstanding. Diluted income per share is calculated by dividing income by the weighted average number of common and potential dilutive common shares outstanding. Diluted income per share takes into consideration the assumed exercise of outstanding stock options resulting in approximately 219,000 and 491,000 potential dilutive common shares for the three months ended March 31, 2012 and 2011 respectively. For the three months ended  March 31, 2012 and 2011, none of the outstanding stock options would have been anti-dilutive.
