Our intangible assets are comprised of both indefinite-lived and finite-lived intangible assets and goodwill. Intangible assets with indefinite lives are not amortized but 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 2025 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 carrying value of goodwill was $193.2 million as of both June 30, 2026 and December 31, 2025.

Our intangible assets, other than goodwill, as of June 30, 2026 and December 31, 2025 were as follows (in thousands):

Amortization expense was $10.5 million and $20.6 million, respectively, for the three- and six-month periods ended June 30, 2026, respectively, and $10.0 million and $19.8 million for the prior-year periods.

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