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 nine months ended September 30, 2012 and 2011 is as follows (dollars in thousands, except per share amounts):

	Three months ended September 30,				Nine months ended September 30,
	2012		2011		2012		2011
Net income attributable to Amphenol Corporation shareholders	$	147,450	$	134,623	$	414,955	$	410,332
Basic weighted average common shares outstanding	161,349,493		167,951,866		161,905,598		171,411,779
Effect of dilutive stock options	2,430,678		1,883,201		2,428,000		2,316,630
Diluted weighted average common shares outstanding	163,780,171		169,835,067		164,333,598		173,728,409
Earnings per share attributable to Amphenol Corporation shareholders:
Basic	$	0.91	$	0.80	$	2.56	$	2.39
Diluted	$	0.90	$	0.79	$	2.53	$	2.36

Excluded from the computations above were anti-dilutive stock options of 5,414,925 and 6,319,513 for the three months ended September 30, 2012 and 2011, respectively, and 4,345,057 and 3,555,165 for the nine months ended September 30, 2012 and 2011, respectively.
