Net Income Per Share [Abstract]

Computation of basic and diluted income per share

The following table sets forth the computation of basic and diluted income per share for the three and six months ended June 30 (in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
Numerator:
Net income attributable to Vicor Corporation	$	220	$	3,066	$	546	$	7,084
Denominator:
Denominator for basic income per share-weighted average shares (1)		41,811		41,798		41,811		41,785
Effect of dilutive securities:
Employee stock options (2)		1		89		8		88
Denominator for diluted income per share – adjusted weighted-average shares and assumed conversions		41,812		41,887		41,819		41,873
Basic income per share	$	0.01	$	0.07	$	0.01	$	0.17
Diluted income per share	$	0.01	$	0.07	$	0.01	$	0.17

(1) Denominator represents weighted average number of Common Shares and Class B Common Shares outstanding.

(2) Options to purchase 536,173 and 231,687 shares of Common Stock for the three months ended June 30, 2012 and 2011, respectively, and options to purchase 1,682,021 and 235,439 shares of Common Stock for the six months ended June 30, 2012 and 2011, respectively, were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of the Common Stock and,

therefore, the effect would be antidilutive.
