Goodwill and Intangible Assets Disclosure [Abstract]

6.	GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

During the years ended December 31, 2012 and 2011, we did not identify an impairment as a result of our annual impairment test and none of our reporting units were at risk of failing step one. In addition, we considered the likelihood of triggering events that might cause us to reassess goodwill on an interim basis and concluded that none had occurred subsequent to our August 1, 2012 valuation date.

The carrying amount of goodwill for each of the two years ended December 31, 2012 is as follows (in thousands):


	Data Center Services		IP Services			Total
Balance, December 31, 2011:
Goodwill	$	20,007	$	152,087		$	172,094
Accumulated impairment losses		—		(112,623	)		(112,623	)
Net	$	20,007	$	39,464		$	59,471

Balance, December 31, 2012:
Goodwill	$	20,141	$	152,087		$	172,228
Accumulated impairment losses		—		(112,623	)		(112,623	)
Net	$	20,141	$	39,464		$	59,605

Other Intangible Assets

During the years ended December 31, 2012 and 2011, we concluded that no impairment indicators existed to cause us to reassess our other intangible assets.

The components of our amortizing intangible assets are as follows (in thousands):


	December 31, 2012					December 31, 2011
	Gross Carrying Amount		Accumulated Amortization			Gross Carrying Amount		Accumulated Amortization
Acquired technology	$	43,627	$	(29,561	)	$	43,627	$	(24,844	)
Customer relationships and trade names		32,247		(24,971	)		32,247		(24,144	)
	$	75,874	$	(54,532	)	$	75,874	$	(48,988	)

Amortization expense for intangible assets during the years ended December 31, 2012, 2011 and 2010 was $5.5 million, $3.5 million and $6.1 million, respectively. As of December 31, 2012, remaining amortization expense is as follows (in thousands):


2013	$	5,546
2014		5,546
2015		2,606
2016		2,018
2017		1,338
