Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill And Other Intangible Assets | Goodwill and Other Intangible Assets Goodwill and indefinite-lived intangible assets are required to be reviewed annually for impairment. Goodwill is tested for impairment at the reporting unit level on an annual basis and between annual tests 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. The Company's annual impairment tests performed in 2022, 2021 and 2020 did not result in the fair value of its reporting unit being less than its carrying value. We performed the step 0 qualitative assessment in 2022 and 2021. The goodwill balance, which relates to one reporting unit, was $171.1 million as of each of December 31, 2022 and 2021. The following table summarizes acquired intangible assets with determinable useful lives by major category which are included in "Other assets" on our Consolidated Balance Sheets:
