Item 3. LEGAL PROCEEDINGS

**

As of December 29, 2018, we have been designated by the U.S. Environmental Protection Agency ("EPA") and/or other responsible state agencies as a potentially responsible party ("PRP") at thirteen waste disposal or waste recycling sites that are the subject of separate investigations or proceedings concerning alleged soil and/or groundwater contamination. No settlement of our liability related to any of the sites has been agreed upon. We are participating with other PRPs at these sites and anticipate that our share of remediation costs will be determined pursuant to agreements that we negotiate with the EPA or other governmental authorities.

We have accrued liabilities for sites where it is probable that a loss or cost will be incurred and the amount of loss or cost can be reasonably estimated. These estimates could change as a result of changes in planned remedial actions, remediation technologies, site conditions, the estimated time to complete remediation, environmental laws and regulations, and other factors. Because of the uncertainties

associated with environmental assessment and remediation activities, future expenses to remediate these sites could be higher than the liabilities we have accrued; however, we are unable to reasonably estimate a range of potential expenses. If information were to become available that allowed us to reasonably estimate a range of potential expenses in an amount higher or lower than what we have accrued, we would adjust our environmental liabilities accordingly. In addition, we may be identified as a PRP at additional sites in the future. The range of expenses for remediation of any future-identified sites would be addressed as they arise; until then, a range of expenses for such remediation cannot be determined.

As of December 29, 2018, our accrued liability associated with environmental remediation was $20 million.

In addition, we are involved in various lawsuits, claims, inquiries, and other regulatory and compliance matters, most of which are routine to the nature of our business. We have accrued liabilities for matters where it is probable that a loss will be incurred and the amount of loss can be reasonably estimated. Because of the uncertainties associated with claims resolution and litigation, future expenses to resolve these matters could be higher than the liabilities we have accrued; however, we are unable to reasonably estimate a range of potential expenses. If information were to become available that allowed us to reasonably estimate a range of potential expenses in an amount higher or lower than what we have accrued, we would adjust our accrued liabilities accordingly. Additional lawsuits, claims, inquiries, and other regulatory and compliance matters could arise in the future. The range of expenses for resolving any future matters would be assessed as they arise; until then, a range of potential expenses for such resolution cannot be determined. Based upon current information, we believe that the impact of the resolution of these matters would not be, individually or in the aggregate, material to our financial position, results of operations or cash flows.
