Basic	375.8	384.7	377.4	386.0
Dilutive effect of stock options	1.2	1.6	1.3	1.7
Dilutive effect of restricted share and restricted share unit awards	1.4	1.5	1.6	1.5
Diluted	378.4	387.8	380.3	389.2

There were no significant outstanding stock-based awards excluded from the computation of diluted EPS during the three and six month periods ended June 30, 2014 and 2013.

The number of common shares outstanding as of June 30, 2014 and 2013 was 374.0 million and 383.4 million, respectively.
