For the three and six months ended June 30, 2010 basic earnings per share was computed using 4,597,000 and 4,595,000 common shares, respectively, and diluted earnings per share was computed using 4,607,000 and 4,603,000 common shares and equivalents, respectively. The computation for the three and six month periods ended June 30, 2011 excluded approximately 155,000 of the Company’s stock options because the exercise price of the options was higher than the average market price during the periods. The computation for the three and six month periods ended June 30, 2010 excluded approximately 360,000 of the Company’s stock options because the exercise price of the options was higher than the average market price during those periods.
