Shares Used in Computing Net Income Per Share

The computation of shares used in calculating basic and diluted net income per common share is as follows:



	Three Months Ended September 30,		Nine Months Ended September 30,
(In millions)	2017	2016	2017	2016
Weighted-average common shares outstanding used for the calculation of net income per share – basic	210.1	219.2	212.1	221.6
Common stock equivalents	4.4	3.5	4.6	3.6
Weighted-average common shares outstanding used for the calculation of net income per share – diluted	214.5	222.7	216.7	225.2

For the three months ended September 30, 2017 and 2016, stock options for 0.7 million and 0.9 million shares, respectively, were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive. For both the nine months ended September 30, 2017 and 2016, stock options for 0.8 million shares were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive.
