Schedule of estimate amortization expense of intangible assets for the future years

Intangible assets with finite lives are being amortized primarily on a straight-line basis over their estimated useful lives.  The weighted average amortization period of our intangible assets with finite lives is 11 years.    Amortization expense on intangible assets for each of the years ended December 31, 2013, 2012, and 2011 was $4.1, $4.3, and $4.8, respectively.  We estimate amortization expense of intangible assets for the future years ending December 31 will approximate the following amounts:

	Amount
2014	$	3.9
2015		3.8
2016		3.8
2017		3.4
2018		3.1
