GOODWILL AND OTHER INTANGIBLE ASSETS

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill is tested annually, or more often than annually if circumstances warrant, for impairment. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated, and goodwill is written down to its implied fair value. Subsequent increases in goodwill value are not recognized in the financial statements. Goodwill totaled $1.32 billion at December 31, 2025 and 2024. Goodwill impairment was neither indicated nor recorded in 2025, 2024 or 2023.
