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 $76,000 and $106,000 for the three months ended September 30, 2015 and 2016, respectively, and $223,000 and $308,000 for the nine months ended September 30, 2015 and 2016, respectively.

During the nine months ended September 30, 2016, we increased prepaid agreements not-to-compete by $0.8 million related to our acquisition of two funeral home businesses in May 2016 and our acquisition of one funeral home business in September 2016 described in Note 3 to the Consolidated Financial Statements included herein.

Our tradenames have indefinite lives and therefore are not amortized. During the three months ended September 30, 2016, 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 income (expense) 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.

During the nine months ended September 30, 2016, we increased tradenames by approximately $3.2 million related to our acquisition of two funeral home businesses in May 2016 described in Note 3 to the Consolidated Financial Statements included herein.
