The following table sets forth Options outstanding pursuant to stock-based compensation plans as of the dates indicated:
|  | November 30, 2013 |  |  | November 30, 2012 |
Options outstanding pursuant to stock-based compensation plans (in millions) |  |  | 4.7 |  |  |  | 4.3 |
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 1.3 million as of November 30, 2013. 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, 2013, $13.4 remains available for future purchases of common shares under the current repurchase authorization of the Board of Directors. See Note 12, “Treasury Stock,” for a more complete description of the Company’s share buy-back program.
