As of March 31, 2016, the Company reviewed the useful lives for its trade name and trademark intangible assets and determined there to be events and circumstances to warrant a revision of the remaining amortization period. In accordance with FASB ASC 350 “Intangibles – Goodwill and Other,” the Company will amortize the remaining carrying amount prospectively over the revised remaining useful lives.

 

The weighted-average amortization period for the intangible assets is 9.9 years. The weighted-average amortization period for customer lists, patents and technology and trade names and trademarks is 10.3, 9.3 and 1.2 years, respectively.

Amortization expense was $3,110 and $2,628 for the quarters ended September 30, 2016 and 2015, respectively. Amortization expense was $9,239 and $7,872 for the nine months ended September 30, 2016 and 2015, respectively.

Estimated annual amortization expense for intangible assets subsequent to September 30, 2016 is as follows:
