For the three months ended October 31, 2013 and 2012, awards to purchase 204,500 and 2,904,808 common shares, respectively, were outstanding but were not included in the Company’s computation of diluted weighted-average shares outstanding because their effect would have been anti-dilutive.

Excluded from the calculation of diluted weighted-average shares outstanding as of October 31, 2013 and October 31, 2012, were 1,751,100 and 1,952,158 performance-based equity awards, respectively, since they did not meet the required performance criteria.
