Intangible Assets - Our intangible assets relate primarily to acquired customer relationships from our recent acquisitions and are being amortized on a straight-line basis over a weighted average life of 26 years. Amortization expense for intangible assets was $138 million in 2025, $62 million in 2024 and $33 million in 2023. The amortization expense for each of the next five years is estimated to be $135 million. The following table reflects the gross carrying amount and accumulated amortization of intangible assets as of the dates presented:

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.
