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, 2013 and 2012 is as follows (dollars in thousands, except per share amounts):

	Three months ended June 30,				Six months ended June 30,
	2013		2012		2013		2012
Net income attributable to Amphenol Corporation shareholders	$	153,988	$	140,942	$	306,995	$	267,505
Basic weighted average common shares outstanding	159,705,021		161,511,550		159,721,503		162,186,707
Effect of dilutive stock options	3,230,407		2,360,015		3,103,326		2,426,645
Diluted weighted average common shares outstanding	162,935,428		163,871,565		162,824,829		164,613,352
