Shares Used in Computing Net Income Per Share

6. 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 June 30,				Six Months Ended June 30,
(In millions)	2015		2014		2015		2014
Weighted-average common shares outstanding used for the calculation of net income per share – basic		236.5		249.3		237.6		251.9
Common stock equivalents		3.9		4.1		4.1		4.1
Weighted-average common shares outstanding used for the calculation of net income per share – diluted		240.4		253.4		241.7		256.0

For the three months ended June 30, 2015 and 2014, stock options for 1.1 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 six months ended June 30, 2015 and 2014, stock options for 0.8 million and 1.1 million shares, respectively, were excluded from the calculation of diluted weighted-average outstanding shares because their impact was anti-dilutive.
