Earnings Per Share

15. Earnings Per Share

        Basic earnings per share (EPS) excludes dilution and is computed by dividing net income available for common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income by the weighted average number of common shares outstanding and potential common shares for the period. The Company includes as potential common shares the weighted average dilutive effects of outstanding stock options and restricted stock units using the treasury stock method. For the periods presented, options excluded from the calculation of potential common shares were not significant. The computation of diluted loss per share for the year ended September 30, 2015 excludes 1.7 million of potential common shares due to their antidilutive effect.

        The following table sets forth a reconciliation of the denominators of basic and diluted earnings per share:

		Fiscal Year Ended
		September 30, 2016			September 30, 2015			September 30, 2014
		(in millions)
Denominator for basic earnings per share			154.8			149.6			97.2
Potential common shares			1.3			—			1.5
