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 six months ended June 30, 2015 and 2014 is as follows:

	Three months ended June 30,				Six months ended June 30,
	2015		2014		2015		2014
Net income attributable to Amphenol Corporation shareholders	$	179.0	$	174.9	$	358.8	$	333.4

Basic weighted average common shares outstanding	308,899,937		314,229,370		309,470,068		314,640,882
Effect of dilutive stock options	7,978,163		7,352,900		7,958,745		7,325,276

Diluted weighted average common shares outstanding	316,878,100		321,582,270		317,428,813		321,966,158

Earnings per share attributable to Amphenol Corporation shareholders:
Basic	$	0.58	$	0.56	$	1.16	$	1.06
Diluted	$	0.56	$	0.54	$	1.13	$	1.03

Excluded from the computations above were anti-dilutive stock options of 1,671,550 and 2,951,100 for the three months ended June 30, 2015 and 2014, respectively, and 2,738,857 and 4,056,342 for the six months ended June 30, 2015 and 2014, respectively.
