In accordance with ASC 260, "Earnings per Share," dilutive options were not included in the computation of diluted loss per share for the three months ended January 31, 2013 and 2012, and the six months ended January 31, 2012, since to do so would reduce the calculated loss per share.
Options to purchase approximately 3,539,000 and 4,365,000 shares of Class A Nonvoting Common Stock for the three months ended January 31, 2013 and 2012, respectively, were not included in the computation of diluted net loss per share because the impact of the inclusion of the options would have been anti-dilutive. Options to purchase approximately 4,044,000 and 4,788,000 shares of Class A Nonvoting Common Stock for the six months ended January 31, 2013 and 2012, respectively, were not included in the computation of diluted net income or loss per share as the impact of the inclusion of the options would have been anti-dilutive.
