Intangible assets:

Total accumulated amortization		(5,040	)		(2,042	)
Intantible assets, net	$	6,147		$	2,858

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 12 months for customer backlog and trade names and trademarks and 15 years for domain names, which approximates the pattern in which the economic benefits are expected to be received. In May 2018, the Company purchased certain domain names for $6.3 million. We evaluate the recoverability of intangible assets periodically and consider 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, 2018 was $3.0 million. As of September 30, 2018, the Company had goodwill of $68.5 million.
