NET INCOME PER COMMON SHARE

Basic net income per common share excludes the dilutive impact of potentially dilutive securities and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per common share includes the effect of potential dilution from the hypothetical exercise of outstanding stock options and vesting of restricted stock units and performance share units. A reconciliation of our basic and diluted net income per common share is as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
(In millions, except per share data)	2023		2022		2023		2022
Net income to common shareholders	$	72.9	$	62.4	$	194.3	$	148.0
Basic weighted average shares outstanding	221.0		220.6		221.3		222.0
Diluted weighted average shares outstanding	221.9		221.2		222.1		222.6
Net income per common share:
Basic net income per share	$	0.33	$	0.28	$	0.88	$	0.67
Diluted net income per share	$	0.33	$	0.28	$	0.87	$	0.66

The number of anti-dilutive shares that have been excluded in the computation of diluted net income per share for the three and nine months ended September 30, 2023 and 2022 were 0.5 million, 0.5 million, 1.1 million and 1.1 million, respectively.
