Earnings Per Share

Note 4: Earnings Per Share

Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company, such as the Company's dilutive stock options.

The following is a reconciliation of basic and diluted earnings per share for the three and nine months ended September 30, 2012 and 2011:
