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 issuable upon the exercise of outstanding 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, 2012 and 2011 is as follows (dollars in thousands, except per share amounts):

	Three months ended June 30,				Six months ended June 30,
	2012		2011		2012		2011
Net income attributable to Amphenol Corporation shareholders	$	140,942	$	147,751	$	267,505	$	275,709
Basic weighted average common shares outstanding	161,511,550		171,194,474		162,186,707		173,170,408
Effect of dilutive stock options	2,360,015		2,397,984		2,426,645		2,536,937
Diluted weighted average common shares outstanding	163,871,565		173,592,458		164,613,352		175,707,345
