Basic and diluted earnings (loss) per share

The following table shows the basic and diluted earnings (loss) per share:

			For the three months ended March 31
			2021																		2020
			Net Income (Loss)						Shares (in millions)						Per Share						Net Income (Loss)						Shares (in millions)						Per Share

Basic and diluted EPS(1)			$	(140.0)					90.1						$	(1.55)					$	(2.7)					89.3						$	(0.03)

(1) In periods when we report a net loss, all share-based compensation awards and convertible preferred shares are excluded from the calculation of diluted weighted average shares outstanding because of their anti-dilutive effect on earnings (loss) per share.
