Earnings Per Share

3 Months Ended

Mar. 31, 2017

Earnings per share

At March 31, 2017, the number of shares outstanding was 146.7 million (March 31, 2016 - 153.0 million).

Basic earnings per share have been calculated using net income for the period divided by the weighted-average number of shares outstanding during the period.

The number of shares used in earnings per share calculations is reconciled as follows:



	For the three months ended March 31
(in millions)	2017	2016
Weighted-average basic shares outstanding	146.5	153.0
Dilutive effect of stock options	0.6	0.8
Weighted-average diluted shares outstanding	147.1	153.8

For the three months ended March 31, 2017, 502,000 options were excluded from the computation of diluted earnings per share because their effects were not dilutive (three months ended March 31, 2016 - 445,991 options).
