Amortization expense is calculated using the straight-line method over the estimated useful lives of the acquired intangibles. IPR&D will be accounted for as an indefinite-lived intangible asset and will not be amortized until the underlying project reaches technological feasibility and commercial production, at which point the IPR&D will be amortized over the estimated useful life. Useful lives for these IPR&D projects are expected to range between 3 to 10 years. In the event the IPR&D is abandoned, the related assets will be written off. The total amortization expense for acquired intangible assets was $114.2 million in fiscal 2025, $81.6 million in fiscal 2024 and $130.4 million in fiscal 2023. This amortization expense was included in the accompanying consolidated statements of operations as acquired intangibles amortization and cost of revenue.
Expected annual aggregate amortization expense in future fiscal years are as follows:

Impairment of indefinite-lived intangible assets
During fiscal 2025, we recorded an intangible asset impairment charge of $13.8 million related to a license of certain technology we acquired in fiscal 2024. We recorded the impairment charge due to a lack of potential customers, no alternative uses for the acquired technology and no further development or investment planned for this project. The impairment charge was presented as an operating expense in our consolidated statement of operations.
During fiscal 2024, we recorded an indefinite-lived intangible asset impairment charge of $16.0 million of IPR&D from our December 2021 acquisition of DSP Group, Inc. (“DSPG”). We recorded the impairment charge as a result of a lack of commitment from certain key customers, no anticipated customer migration to the IPR&D technologies acquired from DSPG and no further development or investment planned for this project. The impairment charge was presented as an operating expense in our consolidated statement of operations.

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.
