NOTE 10. NET INCOME PER COMMON SHARE

Net income per common share was computed as follows:

(In millions, except per share amounts)		2017		2016		2015

(A)	Income from continuing operations	$	281.8	$	320.7	$	274.4
(B)	Loss from discontinued operations, net of tax		–		–		(.1	)

(C)	Net income available to common shareholders	$	281.8	$	320.7	$	274.3

(D)	Weighted average number of common shares outstanding		88.3		89.1		91.0
	Dilutive shares (additional common shares issuable under stock-based awards)		1.8		1.6		1.9

(E)	Weighted average number of common shares outstanding, assuming dilution		90.1		90.7		92.9

Net income per common share:
Continuing operations (A) ÷ (D)		$	3.19	$	3.60	$	3.01
Discontinued operations (B) ÷ (D)			–		–		–

Net income per common share (C) ÷ (D)		$	3.19	$	3.60	$	3.01

Net income per common share, assuming dilution:
Continuing operations (A) ÷ (E)		$	3.13	$	3.54	$	2.95
Discontinued operations (B) ÷ (E)			–		–		–

Net income per common share, assuming dilution (C) ÷ (E)		$	3.13	$	3.54	$	2.95

Certain stock-based compensation awards were not included in the computation of net income per common share, assuming dilution, because they would not have had a dilutive effect. Stock-based compensation awards excluded from the computation were not significant in 2017. Stock-based compensation awards excluded from the computation totaled approximately .2 million shares in 2016 and 1 million shares in 2015.
