There was no impairment expense related to goodwill for each of the years ended December 31, 2022, 2021 and 2020.
Management performed its annual impairment assessment of the carrying value of goodwill as of December 31, 2022 and 2021. For each of our reporting units, we assessed qualitative factors to determine whether the existence of events or circumstances indicated that it was more likely than not that the fair value of the reporting units was less than its carrying amount. Based on the qualitative assessments, management determined that it was not more likely than not that the fair values of the reporting units were less than the carrying values at December 31, 2022 and 2021. A deterioration in any of the assumptions could result in an impairment charge in the future.
