Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

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 test 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 2022 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.

As of both March 31, 2023 and December 31, 2022, our goodwill balance was $0.6 million.

Our intangible assets, other than goodwill, as of March 31, 2023 and December 31, 2022 were as follows (in thousands, except for weighted average remaining useful life):


		As of March 31, 2023			As of December 31, 2022

Amortization expense was $0.6 million and $1.9 million for the three-month periods ended March 31, 2023 and 2022, respectively.

Amortization expense for the remainder of 2023, each of the next four years and thereafter is estimated to be as follows (in thousands):


		Amortization
Years ending December 31,		Expense
2023 (period from April 1 to December 31)		$1,918
2024		$2,566
2025		$2,460
2026		$2,361
2027		$2,141
Thereafter		$6,095

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