Note 8—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, 2011 and 2010 is as follows (dollars in thousands, except per share amounts):

	Three months ended June 30,				Six months ended June 30,
	2011		2010		2011		2010
Net income attributable to Amphenol Corporation shareholders	$	147,751	$	129,671	$	275,709	$	228,024
Basic weighted average common shares outstanding	171,194,474		173,519,882		173,170,408		173,393,698
Effect of dilutive stock options	2,397,984		2,365,583		2,536,937		2,337,393
Diluted weighted average common shares outstanding	173,592,458		175,885,465		175,707,345		175,731,091
Earnings per share attributable to Amphenol Corporation shareholders:
Basic	$	0.86	$	0.75	$	1.59	$	1.32
Diluted	$	0.85	$	0.74	$	1.57	$	1.30

Excluded from the computations above were anti-dilutive common shares of 2,969,325 and 2,944,650 for the three months ended June 30, 2011 and 2010, respectively, and 2,434,686 and 3,080,457 for the six months ended June 30, 2011 and 2010, respectively.
