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, 2014 and 2013 is as follows (dollars in thousands, except per share amounts):

	Three months ended March 31,
	2014		2013
Net income attributable to Amphenol Corporation shareholders	$	158,483	$	153,007
Basic weighted average common shares outstanding	157,528,482		159,738,168
Effect of dilutive stock options	3,648,674		2,974,834
Diluted weighted average common shares outstanding	161,177,156		162,713,002
Earnings per share attributable to Amphenol Corporation shareholders:
Basic	$	1.01	$	0.96
Diluted	$	0.98	$	0.94

Excluded from the computations above were anti-dilutive stock options of 2,764,633 and 1,263,518 for the three months ended March 31, 2014 and 2013, respectively.
