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)	2018	2017	2018	2017
Weighted-average common shares outstanding used for the calculation of net income per share – basic	403.8	420.2	408.4	424.3
Common stock equivalents	8.2	8.9	8.2	9.1
Weighted-average common shares outstanding used for the calculation of net income per share – diluted	412.0	429.1	416.6	433.4

For the three months ended September 30, 2018 and 2017, stock options for 1.2 million and 1.4 million shares, respectively, were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive. For the nine months ended September 30, 2018 and 2017, stock options for 1.0 million and 1.5 million shares, respectively, were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive.
