Goodwill and Intangible Assets Disclosure [Abstract]  
Goodwill Goodwill
Goodwill represents the excess of the aggregate purchase price over the fair value of the identifiable net assets acquired and is not amortized. We perform an annual assessment of whether goodwill retains its value. This assessment is done more frequently if indicators of potential impairment exist. We performed our annual goodwill impairment review in the fourth quarter of 2022, 2021, and 2020. We performed a qualitative assessment for the years ended December 31, 2022, December 31, 2021, and December 31, 2020. In 2022, 2021 and 2020, the annual impairment review resulted in the determination that no indicators of impairment of goodwill were present.
