In conjunction with our segment realignment we completed a goodwill impairment test in the first quarter of 2012 and concluded that there was no impairment. In the fourth quarters of 2012, 2011, and 2010, we completed our required annual impairment test and also concluded that there was no impairment.

Other acquisition intangibles consisted of the following major classes:


	Weighted Average Useful Life (years)		Gross Carrying Value				Accumulated Amortization						Net Carrying Value
December 31,	2012		2012		2011		2012			2011			2012		2011
Technology-based		14.5	$	48.6	$	23.0	$	(20.6	)	$	(17.7	)	$	28.0	$	5.3
Marketing-related		10.0		15.1		5.0		(5.2	)		(4.3	)		9.9		0.7
Customer-related		15.8		163.9		18.9		(18.1	)		(12.7	)		145.8		6.2

Total			$	227.6	$	46.9	$	(43.9	)	$	(34.7	)	$	183.7	$	12.2

Amortization of acquisition intangibles for the years ended December 31, 2012, 2011, and 2010 was $9.0, $3.2, and $3.2, respectively. Assuming no change in the gross carrying amount of acquisition intangibles and that the 2012 average exchange rates remain constant, the estimated future amortization expense for the next five years is as follows:


	2013		2014		2015		2016		2017
Intangibles Amortization Expense	$	15.2	$	14.8	$	14.7	$	14.5	$	13.5
