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 EPS. The average number of common shares outstanding is reconciled to those used in the basic and diluted EPS computations as follows:

		Three Months Ended March 31
(Millions of shares)		2018			2017
Basic		350.4			356.0
Dilutive effect of stock options and restricted share unit awards		2.2			2.6
Diluted		352.6			358.6

The impact of 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 was insignificant. The number of common shares outstanding as of March 31, 2018 and 2017 was 349.6 million and 355.2 million, respectively.
