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)	2016	2015	2014
Basic	359.4	363.8	374.5
Dilutive effect of stock options and restricted share unit awards	2.3	2.5	2.9
Diluted	361.7	366.3	377.4

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 December 31, 2016, 2015 and 2014 was 356.6 million, 360.9 million and 365.3 million, respectively.
