Stock options are anti-dilutive and excluded from the earnings per share calculation if the exercise price exceeds the average market price of the common shares. There were 11.3 million outstanding options to purchase common shares that were anti-dilutive and excluded from the first quarter earnings per share calculation as of November 30, 2018 compared to 7.6 million as of November 30, 2017.
