For 2012, 2011 and 2010, 164,560, 140,370, and 111,210 shares, respectively, attributable to outstanding stock options were excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. For 2010 all outstanding restricted shares were included in the calculation of diluted earnings per common share because the unrecorded compensation and tax benefits to be credited to capital in excess of par for all awards of restricted stock were lower than the average price of the common shares, and therefore were dilutive.
