Earnings (Loss) per Share [Abstract]



9.	(Loss) Earnings per Share

Basic (loss) earnings per share is computed by dividing net (loss) income by the number of weighted-average shares outstanding during the period. Diluted (loss) earnings per share is computed using the weighted-average shares outstanding and, if dilutive, potential ordinary shares outstanding during the period. Potential ordinary shares represent the incremental ordinary shares issuable for restricted share units and share option exercises. The Company calculated the dilutive effect of outstanding restricted share units and share options on (loss) earnings per share by application of the treasury stock method. Dilutive securities, including participating securities, are not included in the computation of loss per share when the Company reports a net loss from continuing operations as the impact would be anti-dilutive.

The weighted-average number of shares outstanding used in the computations of basic and diluted (loss) earnings per share were as follows (in millions):



	Fiscal Year
	2019	2018	2017
Basic	83.9	84.0	97.7
Dilutive impact of restricted share units and share options	—	—	0.2
Diluted	83.9	84.0	97.9

The computation of diluted weighted-average shares outstanding for fiscal 2019, 2018 and 2017 excluded approximately 6.3 million, 3.3 million and 4.2 million, respectively, shares of equity award because the effect would have been anti-dilutive.
