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 months ended March 31, 2012 and 2011 is as follows (dollars in thousands, except per share amounts):

	Three months ended March 31,
	2012		2011
Net income attributable to Amphenol Corporation	$	126,563	$	127,958
Basic weighted average common shares outstanding	162,861,863		175,168,297
Effect of dilutive stock options	2,493,275		2,682,635
Diluted weighted average common shares outstanding	165,355,138		177,850,932
Earnings per share attributable to Amphenol Corporation:
Basic	$	0.78	$	0.73
Diluted	$	0.77	$	0.72

Excluded from the computations above were anti-dilutive common shares of 4,185,293 and 49,000 for the three months ended March 31, 2012 and 2011, respectively.
