Earnings per Common Share

Basic earnings per common share excludes dilution and is computed by dividing income available to common shareholders by the weighted-average common shares outstanding during the period. Diluted earnings per common share takes into account the potential dilution that would occur if in-the-money stock options were exercised and converted into common shares and restricted stock awards and performance-based stock awards were vested. Proceeds assumed to have been received on option exercises are assumed to be used to purchase shares of the Corporation’s common stock at the average market price during the period, as required by the treasury stock method of accounting. The effects of stock options are excluded from the computation of diluted earnings per share in periods in which the effect would be antidilutive.
