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)	2017	2016
Basic	356.0	360.7
Dilutive effect of stock options and restricted share unit awards	2.6	2.7
Diluted	358.6	363.4

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 March 31, 2017 and 2016 was 355.2 million and 360.2 million, respectively.
