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 outstanding, which relates to stock options. A reconciliation of the basic average common shares outstanding to diluted average common shares outstanding as of December 31 is as follows (dollars in thousands, except per share amounts):

	2012		2011		2010
Net income attributable to Amphenol Corporation shareholders	$	555,317	$	524,191	$	496,405
Basic average common shares outstanding	161,522,080		169,640,115		173,785,650
Effect of dilutive stock options	2,425,031		2,185,473		2,540,343
Dilutive average common shares outstanding	163,947,111		171,825,588		176,325,993
Earnings per share:
Basic	$	3.44	$	3.09	$	2.86
Diluted	$	3.39	$	3.05	$	2.82

Excluded from the computations above were anti-dilutive common shares of 4,551,578, 4,286,519 and 2,570,500 for the years ended December 31, 2012, 2011 and 2010, respectively.
