Note 7—Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income attributable to Amphenol Corporation by the weighted average number of common shares outstanding.  Diluted EPS is computed by dividing net income attributable to Amphenol Corporation by the weighted average number of common shares and dilutive common shares outstanding, which relates to stock options.  A reconciliation of the basic weighted average common shares outstanding to diluted weighted average common shares outstanding for the three months ended March 31, 2018 and 2017 is as follows:

	Three Months Ended March 31,
(dollars and shares in millions, except per share data)	2018		2017
Net income attributable to Amphenol Corporation shareholders	$	265.6	$	224.9
Basic weighted average common shares outstanding		303.7		306.6
Effect of dilutive stock options		12.3		9.8
Diluted weighted average common shares outstanding		316.0		316.4
Earnings per share attributable to Amphenol Corporation shareholders:
Basic	$	0.87	$	0.73
Diluted	$	0.84	$	0.71

There were no anti-dilutive common shares excluded from the computations above for both the three months ended March 31, 2018 and 2017.
