Earnings per Common Share |
Earnings per Common Share | (2) 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 reduced by unearned ESOP Plan shares and treasury shares. Diluted earnings per common share takes into account the potential dilution computed pursuant to the treasury stock method that could occur if stock options were exercised and converted into common stock and if restricted stock awards were vested. The effects of stock options are excluded from the computation of diluted earnings per share in periods in which the effect would be anti-dilutive. ​
