As of June 30, 2013 and December 31, 2012, intangible assets, net of accumulated amortization, were as follows (in thousands):

		As of June 30, 2013					As of December 31, 2012
	Weighted Average Amortization Period (in years)	Gross Carrying Amount		Accumulated Amortization			Gross Carrying Amount		Accumulated Amortization
Core and developed technology	10	$	10,257	$	(4,076	)	$	10,257	$	(3,546	)
Non-compete agreement	2	170		(170		)	170		(170		)
Total intangible assets	10	$	10,427	$	(4,246	)	$	10,427	$	(3,716	)

Amortization is computed using the straight-line method over the useful lives of the respective intangible assets as there is no other pattern of use that is reasonably estimable. Amortization expense was approximately $0.3 million for each of the three months ended June 30, 2013 and 2012. Amortization expense was approximately $0.5 million for each of the six months ended June 30, 2013 and 2012.

The Company expects to incur amortization expense of appropriately $1.1 million per year for each of the next five years.
