Note 6—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 and nine months ended September 30, 2015 and 2014 is as follows:

	Three months ended September 30,				Nine months ended September 30,
	2015		2014		2015		2014
Net income attributable to Amphenol Corporation shareholders	$	204.5	$	182.2	$	563.3	$	515.6

Basic weighted average common shares outstanding	308,853,642		313,284,242		309,262,335		314,183,699
Effect of dilutive stock options	7,032,954		7,352,163		7,646,756		7,334,337

Diluted weighted average common shares outstanding	315,886,596		320,636,405		316,909,091		321,518,036

Earnings per share attributable to Amphenol Corporation shareholders:
Basic	$	0.66	$	0.58	$	1.82	$	1.64
Diluted	$	0.65	$	0.57	$	1.78	$	1.60

Excluded from the computations above were anti-dilutive stock options of 9,388,150 and 6,169,900 for the three months ended September 30, 2015 and 2014, respectively, and 5,033,840 and 4,695,200 for the nine months ended September 30, 2015 and 2014, respectively.
