Goodwill And Intangible Assets Disclosure [Abstract]

8.	Intangible Assets

Our intangible assets are comprised of both indefinite-lived and finite-lived intangible assets. Intangible assets with indefinite lives are not amortized; rather, they are reviewed for impairment at least annually or whenever events or circumstances indicate the carrying value of the asset may not be recoverable. We perform our annual impairment tests of our indefinite-lived intangible assets during the fourth quarter of each fiscal year, and the results from the test performed in the fourth quarter of 2020 indicated no impairment. We also reevaluate the useful life of indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support an indefinite useful life. The results of our annual indefinite-lived intangible assets impairment assessments in the fourth quarter of 2020 indicated no impairment.

As of both March 31, 2021 and December 31, 2020, our goodwill balance was $0.6 million.

Our intangible assets, other than goodwill, as of March 31, 2021 and December 31, 2020 were as follows (in thousands, except for weighted average remaining useful life):

Amortization expense for the remainder of 2021, each of the next four years and thereafter is estimated to be as follows (in thousands):

Actual future amortization expense could differ from the estimated amount as a result of future investments and other factors.
