(2)The foreign currency translation line item reflects changes in goodwill resulting from fluctuating exchange rates related to the consolidation of certain international subsidiaries.
For the 2025 and 2024 annual impairment testing, based on our qualitative assessments, we concluded that goodwill is not impaired.
The aggregate carrying amount of intangible assets of $229.4 million is included in Intangible Assets, net in our Consolidated Balance Sheet as of December 31, 2025. As of December 31, 2025, and December 31, 2024, the gross book value and accumulated amortization of the intangible assets with definite lives were as follows:

During 2023, we recorded an impairment charge related to our indefinite-lived intangible asset. As a result of reduced long-term advertising and subscription revenue expectations for our Serial podcasts, we performed an interim quantitative impairment test for the Serial indefinite-lived intangible asset. We compared the fair value of the Serial trademark, calculated using a discounted cash flow model, to its carrying value and recorded an impairment charge of approximately $2.5 million for the year ended December 31, 2023. This charge is included in Impairment charges in our Consolidated Statement of Operations. The 2025, 2024 and 2023 annual impairment tests did not identify any impairments to indefinite-lived intangible assets. See Note 2 for factors that the Company considers when assessing indefinite-lived intangible assets for impairment.
Amortization expense for intangible assets included in Depreciation and amortization in our Consolidated Statements of Operations for the years ended December 31, 2025, December 31, 2024, and December 31, 2023 was $27.6 million, $27.5 million and $29.3 million, respectively.

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
