The following table sets forth the reconciliation of the numerator and denominator of basic and diluted earnings per share, as calculated using the treasury stock method for the three months ended November 30, 2016 and the two-class method for the six months ended November 30, 2016. For the three and six months ended November 30, 2015, the two-class method was used to compute basic earnings per share, while the treasury stock method was utilized for the purpose of computing diluted earnings per share, as that method resulted in the most-dilutive earnings per share.

(1)

Represents the number of shares that would be issued if our contingently convertible notes were converted. We include these shares in the calculation of diluted EPS as the conversion of the notes may be settled, at our election, in cash, shares of our common stock, or a combination of cash and shares of our common stock.

(2)

Restricted shares totaling 1,169,393 and 919,918 for the three and six months ended November 30, 2015, respectively, were excluded from the calculation of diluted earnings per share because the grant price of the restricted shares exceeded the average market price of the shares during the period and their effect, accordingly, would have been anti-dilutive. There were no restricted shares identified as being anti-dilutive for the three and six months ended November 30, 2016. In addition, stock appreciation rights (SARs) totaling 1,400,000 for the three and six months ended November 30, 2015 were excluded from the calculation of diluted earnings per share as their effect would have been anti-dilutive.
