Intangible Assets, Net and Goodwill
INTANGIBLE ASSETS, NET AND GOODWILL
Intangible assets that are determined to have finite lives include patents, purchased technology and customer relationships and are amortized over their estimated useful lives, which range from approximately 3 to 10 years, and are measured for impairment only when events or circumstances indicate the carrying value may be impaired. Goodwill and intangible assets with indefinite useful lives, including trademarks and trade names, are not amortized but are periodically evaluated for impairment. At December 31, 2017 and 2016, the Company determined that its goodwill and intangible assets were not impaired.
