Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Other Intangible Assets | Note 7. Goodwill and Other Intangible Assets Goodwill represents the excess of the consideration paid over the fair value of the net assets acquired or the excess of the fair value of the net liabilities assumed over the consideration received in a business combination. The carrying amount of goodwill was $925.4 million at December 31, 2025 and $855.5 million at December 31, 2024. For information regarding changes to the Company’s carrying amount of goodwill and other intangibles, refer to Note 2 – Acquisition. The Company completed its annual impairment test of goodwill as of September 30, 2025 by performing a qualitative (Step Zero) assessment. The qualitative assessment involved the examination of changes in macroeconomic conditions, industry and market conditions, overall financial performance, cost factors and other relevant entity-specific events, including changes in management and other key personnel and changes in the share price of the Company’s common stock. As a result of the assessment, the Company concluded that its goodwill was not impaired. No goodwill impairment charges were recognized during the years ended December 31, 2025, 2024 or 2023. Identifiable intangible assets with finite lives are amortized over the periods benefited and are evaluated for impairment similar to other long-lived assets. The purchase and carrying values of intangible assets subject to amortization at December 31, 2025 and 2024 were as follows:
