Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share ("EPS")

There are no adjustments required to be made to net income for purposes of computing basic and diluted EPS. The average number of common shares outstanding is reconciled to those used in the basic and diluted EPS computations as follows:

(Millions of shares)		2018			2017			2016
Basic		348.0			353.6			359.4
Dilutive effect of stock options and restricted share unit awards		1.6			2.3			2.3
Diluted		349.6			355.9			361.7

Options outstanding that were not included in the computation of diluted EPS because their exercise price was greater than the average market price of the common shares were insignificant. The number of common shares outstanding as of December 31, 2018, 2017 and 2016 was 345.0 million, 351.1 million and 356.6 million, respectively.
