Other Intangible Assets
Other intangible assets are comprised of assets with indefinite lives not subject to amortization and assets with definite lives subject to amortization. Other intangible assets primarily consist of customer lists and trade names, which have definitive lives and are subject to amortization on a straight-line basis with estimated useful lives generally between 7 and 15 years. Amortization expense for other intangible assets for the years ended December 31, 2013, 2012 and 2011 was $26.8, $23.4 and $20.2, respectively. There were no material impairment charges on other intangibles for the years ended December 31, 2013, 2012 and 2011.
