The change in the gross value of our purchased intangible assets from December 31, 2018 to June 30, 2019 was due to foreign currency translation and an adjustment due to the recognition of tax benefit of tax amortization previously applied to certain goodwill related to the NobelClad and DynaEnergetics reporting units. After the goodwill was written off at September 30, 2017 and December 31, 2015, respectively, the tax amortization reduces other noncurrent intangible assets related to the historical acquisition.
