For fiscal 2012, 2011 and 2010 the Company excluded 2.4 million shares, 1.9 million shares and 1.8 million shares of outstanding stock options, respectively, from the calculation of diluted earnings per share because the exercise prices of these stock options were greater than or equal to the average market value of the common shares during the respective periods. Inclusion of these shares would be antidilutive. These options could be included in the calculation in the future if the average market value of the common shares increases and is greater than the exercise price of these options.
