[1] For the three month period ended February 28, 2015, basic weighted-average shares outstanding and basic net income available to common shareholders under the treasury method are used in calculating basic and diluted earnings per share as a result of the reported loss for the period. For the three month period ended February 28, 2014, basic weighted-average shares outstanding and basic net income available to common shareholders are used in calculating diluted earnings per share under the two-class method, as that method resulted in the most dilutive earnings per share.
[2] For the nine month periods ended February 28, 2015 and 2014, approximately 2,995,000 and 3,019,000 shares of stock, respectively, granted under stock-based compensation plans were excluded from the calculation of diluted EPS for those periods, as the effect would have been anti-dilutive.
