Earnings Per Share

The Company calculates basic EPS using the weighted average number of common shares outstanding during the period. Diluted EPS is calculated using the same method as basic EPS, but the Company adds the number of additional common shares that would have been outstanding for the period if the potential dilutive common shares had been issued. The following is the reconciliation between the number of weighted average shares used in the basic and diluted EPS calculations for the three and nine month periods ended September 30, 2012 and 2011:
