The following table sets forth Options outstanding pursuant to stock-based compensation plans as of the dates indicated:

Options outstanding pursuant to stock-based compensation plans (in millions)	4.5	4.7

Earnings from continuing operations exclude earnings of $0.1 and $0.1 for the three and six months ended November 30, 2014, respectively, and $0.1 and $0.1 for the three and six months ended November 30, 2013, respectively, attributable to participating Restricted Stock Units (“RSUs”).

In a period in which the Company reports a discontinued operation, Earnings (loss) from continuing operations is used as the “control number” in determining whether potentially dilutive common shares are dilutive or anti-dilutive. Potentially dilutive shares outstanding pursuant to compensation plans that were not included in the diluted earnings per share calculation because they were anti-dilutive were 1.7 million as of November 30, 2014.

A portion of the Company’s RSUs which are granted to employees participate in earnings through cumulative non-forfeitable dividends payable to the employees upon vesting of the RSUs. Accordingly, the Company measures earnings per share based upon the lower of the Two-class method or the Treasury Stock method. Since, under the Two-class method, losses are not allocated to the participating securities, in periods of loss the Two-class method is not applicable.

As of November 30, 2014, $9.9 remained available for future purchases of common shares under the current repurchase authorization of the Board of Directors. See Note 10, “Treasury Stock,” for a more complete description of the Company’s share buy-back program.
