The Company tests its goodwill balances for impairment in the second quarter of each calendar year. The 2017 and 2016 tests indicated no impairment. The following table presents the components of other intangible assets, all of which have finite lives, as of December 31, 2017 and 2016. The year-over-year changes in gross carrying values mainly resulted from the effects of foreign currency translation.
