Note 3 – Earnings Per Share
 
Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net income by the sum of the weighted-average number of common shares outstanding and the weighted-average number of potential common shares outstanding. There were no anti-dilutive shares in the three-month and nine-month periods ended September 30, 2011 and 2010. The calculations of basic and diluted earnings per share are as follows:
