As a result of the annual indefinite-lived asset impairment review in the fourth quarter of 2016, the Company determined that the trademark at one reporting unit was impaired and therefore recorded a pre-tax charge of $6.6 million in the consolidated statement of income.

The Company recorded $8.3 million, $8.6 million, and $9.0 million of amortization for the years ended December 31, 2016, 2015 and 2014, respectively.

Customer relationships, product technology and patents are amortized over their useful lives ranging from 8 to 17 years. The weighted average estimated useful life of intangible assets subject to amortization is approximately 11 years.

The estimated amortization expense for intangible assets is approximately $9.1 million in 2017 and in each of the next four years and then $58.9 million thereafter.
