Commitments and Contingencies Disclosure [Abstract] |
Commitments and contingencies | NOTE 13. COMMITMENTS AND CONTINGENCIES In the ordinary course of conducting its business, the Company becomes involved in litigation, administrative proceedings and governmental investigations, including environmental matters. At November 30, 2021 and August 31, 2021, the amounts accrued for cleanup and remediation costs at certain sites in response to statutes enforced by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ("CERCLA") were immaterial. Total accrued environmental liabilities, including CERCLA sites, were $5.2 million and $7.1 million at November 30, 2021 and August 31, 2021, respectively, of which $2.2 million and $2.3 million were classified as other long-term liabilities at November 30, 2021 and August 31, 2021, respectively. These amounts have not been discounted to their present values. Due to evolving remediation technology, changing regulations, possible third-party contributions, the inherent uncertainties of the estimation process and other factors, amounts accrued could vary significantly from amounts paid.
