In the first and second quarters of 2021, the Company performed its ongoing assessment to consider whether events or circumstances had occurred that could more likely than not reduce the fair value of a reporting unit below its carrying value. After evaluating and weighing all relevant events and circumstances, the Company concluded that it is not more likely than not that the fair values of any of its reporting units were less than their carrying values. Consequently, the Company determined that it was not necessary to perform an interim impairment test for any of its reporting units.

To the extent the COVID-19 pandemic continues to disrupt the economic environment, such as a decline in the performance of the reporting units or loss of a significant contract or multiple significant contracts, the fair value of one or more of the reporting units could fall below their carrying value, resulting in a goodwill impairment charge.
