5. GOODWILL AND OTHER INTANGIBLE ASSETS, NET

The carrying amount of goodwill by reportable segment at December 31, 2020 and 2019 was $14.2 million for Trex Residential and $54.3 million for Trex Commercial.

The Company’s intangible assets consist of domain names purchased in May 2018. At December 31, 2020 and 2019, intangible assets were $6.3 million, and accumulated amortization was $1.1 million and $0.7 million, respectively. Intangible asset 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 years ended December 31, 2020, December 31, 2019 and December 31, 2018, was $0.4 million, $0.4 million and $3.1 million, respectively. Intangible asset amortization expense for the year ended December 31, 2018 included amortization expense for customer backlog and trade names and trademarks, which were fully amortized as of December 31, 2018.
