Diluted	$	(1.75	)	$	(1.81	)

* In each of the three month periods ended August 31, 2018 and 2017, the Company experienced a loss from operations and therefore did not report any dilutive share impact.

Options outstanding pursuant to stock-based compensation plans (in millions)	2.7	2.6

There were 0.4 million of potentially anti-dilutive shares pursuant to compensation plans as of August 31, 2018.

A portion of the Company’s Restricted Stock Units ("RSUs") which are granted to employees participate in earnings through cumulative 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 August 31, 2018, $61.4 remained available for future purchases of common shares under the repurchase authorization of the Board of Directors (the "Board") in effect on that date. See Note 11, Treasury Stock, for a more complete description of the Company’s share buy-back program.
