Goodwill and Intangible Assets

As of March 31, 2019 and December 31, 2018, the net carrying value of goodwill was zero. We recorded a total goodwill impairment charge of $190.7 million in December 2018 in connection with our quantitative impairment analysis. We have not acquired additional goodwill in the three months ended March 31, 2019.

The net carrying amounts of our intangible assets other than goodwill as of March 31, 2019 and December 31, 2018 were as follows:

Our finite-lived trademarks will be amortized on a straight-line basis over their remaining useful lives, which range from approximately 1 to 7 years, with a weighted-average remaining useful life of approximately 5 years. Amortization expense on intangible assets for the three months ended March 31, 2019 and 2018 was $5.2 million and $5.1 million, respectively. The amortization of intangible assets is reported on a separate line item in our unaudited Condensed Consolidated Statements of Operations.

Estimated aggregate intangible asset amortization expense for the next five years is as follows (in millions):



2019	$	20.6
2020	12.5
2021	10.8
2022	8.1
2023	7.3
