Other Intangibles

All of the Company’s other intangible assets have been assigned definite lives and continue to be amortized over their useful lives, except for $30,681,000 related to trademarks, which have indefinite lives. The changes in intangible balances reflected on the balance sheet from December 31, 2013 to September 30, 2014 were the result of foreign currency translation and amortization except for intangible impairment write-downs, noted below, which totaled $8,253,000.

The Company evaluates the carrying value of definite-lived assets whenever events or circumstances indicate possible impairment. Definite-lived assets are determined to be impaired if the future un-discounted cash flows expected to be generated by the asset are less than the carrying value. Actual impairment amounts for definite-lived assets are then calculated using a discounted cash flow calculation. The Company reviews indefinite-lived assets for impairment annually in the fourth quarter of each year and whenever events or circumstances indicate possible impairment. Any impairment amounts for indefinite-lived assets are calculated as the difference between the future discounted cash flows expected to be generated by the asset less than the carrying value for the asset.

For the quarter ended September 30, 2014, the Company recognized intangible impairment write-down charges of $8,103,000 for a customer list and $150,000 for a non-compete agreement in the IPG segment as the actual and remaining cash flows associated with the intangibles were less than the cash flow originally used to value the intangibles, primarily driven by reduced net sales. The after-tax and pre-tax impairment amounts were the same for each of the above impairments.
