Goodwill and Intangible Assets Disclosure [Abstract]

All of the Company’s other intangible assets have been assigned definite lives and continue to be amortized over their useful lives, except for $25,934,000 related to trademarks, which have indefinite lives. The changes in intangible balances reflected on the balance sheet from December 31, 2014 to March 31, 2015 were the result of foreign currency translation and amortization.

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. The Company's intangibles consist of the following (in thousands):
