Options to purchase approximately 3,860,000 and 2,537,000 shares of Class A Nonvoting Common Stock for the three months ended January 31, 2015 and 2014, respectively, and 3,878,000 and 2,521,000 shares for the six months ended January 31, 2015 and 2014, respectively, were not included in the computation of diluted net earnings or loss per share because the option exercise price was greater than the average market price of the common shares and, therefore, the effect would have been anti-dilutive.
