An evaluation of the carrying value of goodwill and other indefinite-lived intangibles is required to be performed on an annual basis, and on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. There have been no events or changes in circumstances which indicate an interim impairment review is required in 2025. The Company will perform the annual analysis during the fourth quarter of 2025.
