Prepaid agreements not-to-compete are amortized over the term of the respective agreements, ranging generally from one to ten years. Amortization expense was approximately $349,000, $300,000 and $435,000 for the years ended December 31, 2014, 2015 and 2016, respectively. During the year ended December 31, 2016, we increased prepaid agreements not-to-compete by $1.6 million related to our 2016 acquisitions described in Note 3 to the Consolidated Financial Statements included herein.

Our tradenames have indefinite lives and therefore are not amortized. During the year ended December 31, 2016, we increased tradenames by approximately $3.0 million related to our 2016 acquisitions described in Note 3 to the Consolidated Financial Statements included herein. We recorded an impairment to tradenames of $145,000 related to a funeral home business held for sale at September 30, 2016, as the carrying value exceeded its fair value. The impairment was recorded in Other, net on our Consolidated Statements of Operations. See Note 1 to the Consolidated Financial Statements included herein, for a discussion of the methodology used for our annual indefinite-lived intangible asset impairment test.
