LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES

Legal Proceedings

We are party to various legal proceedings arising in the ordinary course of business. We are not currently a party to any legal proceeding that management believes could have a material adverse effect on our Consolidated Balance Sheet, Consolidated Statement of Operations or Consolidated Statement of Cash Flows.

Environmental Matters

Site Remediation

Under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) – commonly known as the Superfund – and similar state laws, we:

are a party to various proceedings related to the cleanup of hazardous waste sites and

have been notified that we may be a potentially responsible party related to the cleanup of other hazardous waste sites for which proceedings have not yet been initiated.

As of June 30, 2020, our total accrual for future estimated remediation costs on active Superfund sites and other sites for which we are potentially responsible was approximately $61 million. These amounts are recorded in "Accrued liabilities" and "Other liabilities" on our Consolidated Balance Sheet.

Asset Retirement Obligations

We have obligations associated with the retirement of tangible long-lived assets consisting primarily of reforestation obligations related to forest management licenses in Canada and obligations to close and cap landfills. Some of our sites have asbestos containing materials. We have met our current legal obligation to identify and manage these materials. In situations where we cannot reasonably determine when asbestos containing materials might be removed from the sites, we have not recorded an accrual because the fair value of the obligation cannot be reasonably estimated. As of June 30, 2020, we had an asset retirement obligation reserve of $32 million. These obligations are recorded in "Accrued liabilities" and "Other liabilities" on our Consolidated Balance Sheet.
