Intangible Assets
Intangible Assets
We include in our amortizable intangible assets those intangible assets acquired in our business and asset acquisitions. We amortize acquired intangible assets with finite lives over their estimated economic lives, generally using the straight-line method. Each period, we evaluate the estimated remaining useful lives of acquired intangible assets to determine whether events or changes in circumstances warrant a revision to the remaining period of amortization. Acquired intangibles are removed from the accounts when fully amortized and no longer in use.
Intangible assets consist of the following as of June 30, 2016 and 2015:
 
Gross Carrying Amount
 
Accumulated Amortization
 
Effect of currency translation
 
Net Carrying Amount
 
Weighted Average Remaining Life (in Years)
 
(Dollars in Thousands)
