(in millions except share amounts presented in thousands)	2019		2018		2017
Income from discontinued operations attributable to common shareholders for basic and dilutive earnings per share	$	(0.9)	$	251.8	$	24.8
Net income attributable to common shareholders for basic and diluted earnings per share	471.5		609.2		362.4
Anti-dilutive stock options excluded from EPS calculation (1)	1		813		321
