RECONCILIATION OF WEIGHTED AVERAGE SHARES OUTSTANDING

NOTE 3 RECONCILIATION OF WEIGHTED AVERAGE SHARES OUTSTANDING

Below is a reconciliation of basic to diluted shares outstanding:

		Year Ended December 31,
		2017	2016	2015
Basic		191.1	192.7	200.1
Dilutive effect of shares issuable under stock-based compensation plans		3.1	2.7	3.3
Diluted		194.2	195.4	203.4
	Antidilutive options to purchase common shares and restricted stock as well as contingently issuable restricted stock which are excluded from the table above	0.6	0.6	0.7

The calculation of diluted EPS requires certain assumptions regarding the use of both cash proceeds and assumed proceeds that would be received upon the exercise of stock options and vesting of restricted stock outstanding as of December 31,2017, 2016 and 2015. The assumed proceeds in 2017do not include Excess Tax Benefits pursuant to the prospective adoption of ASU 2016-09 in the first quarter of 2017. The assumed proceeds in 2016 and 2015 include Excess Tax Benefits.

The decrease in the diluted shares outstanding primarily reflects treasury share repurchases under the Company’s Board authorized share repurchase program.
