Goodwill and Other Intangible Assets Goodwill and Other Intangible Assets
The Company tests for goodwill impairment annually, or more frequently if indicators of impairment exist, or if a decision is made to dispose of a business.  The Company performs its annual goodwill impairment test as of October 1 and monitors for triggering events on an ongoing basis. During the three months ended June 30, 2022, there was a triggering event due to lower near-term earnings expectations due to the impacts of inflation. As a result, a goodwill impairment charge of $104.6 million was recorded for the Clean Earth reporting unit. This charge had no impact on the Company's cash flows or compliance with debt covenants.

During the nine months ended September 30, 2023, the Company determined that there were no events or indicators present that would indicate that it was more-likely-than-not that its reporting units' fair values were less than their carrying amounts, which would require a further interim impairment analysis.  However, a continued economic downturn, including continued cost inflation and labor shortages, as well as rising interest rates, could impact the Company's future projected cash flows and discount rates used to estimate fair value, which could result in an impairment charge to any of the Company's reporting units in a future period.
