The carrying value of goodwill at September 30, 2026 and December 31, 2025 was $313.7 million. There were no changes to the carrying value of goodwill from January 1 through September 30, 2026. Goodwill at each reporting unit is evaluated for potential impairment annually, as of the beginning of the fourth quarter, and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. The process of evaluating goodwill for potential impairment is subjective and requires significant estimates, assumptions and judgments particularly related to the identification of reporting units, the assignment of assets and liabilities to reporting units and estimating the fair value of each reporting unit. No impairment charges were recognized during the three and nine months ended September 30, 2026 and 2025.
