7. | GOODWILL AND OTHER INTANGIBLE ASSETS
The carrying amount of goodwill by reportable segment at September 30, 2021 and December 31, 2020 was $14.2 million for Trex Residential and $54.3 million for Trex Commercial. The Company’s intangible assets consist of domain names. At September 30, 2021 and December 31, 2020, intangible assets were $6.3 million and accumulated amortization was $1.4 million and $1.1 million, respectively. Intangible asse t amounts were determined based on the estimated economics of the asset and are amortized over the estimated useful lives on a straight-line basis over 15 years, which approximates the pattern in which the economic benefits are expected to be received. The Company evaluates the recoverability of intangible assets periodically and considers events or circumstances that may warrant revised estimates of useful lives or that may indicate an impairment. Intangible asset amortization expense for the nine months ended September 30, 2021 and September 30, 2020 was $0.3 million and $0.3 million, respectively.
