Note 13. Commitments and Contingencies Legal Proceedings 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. When it is probable that a loss will be incurred and where a range of the loss can be reasonably estimated, the best estimate within the range is accrued. When the best estimate within the range cannot be determined, the low end of the range is accrued. The ultimate resolution of these claims could affect future results of operations should our exposure be materially different from our estimates or should liabilities be incurred that were not previously accrued. Potential insurance reimbursements are not offset against potential liabilities. 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. Environmental Expenditures Environmental expenditures are generally expensed. However, environmental expenditures for newly acquired assets and those which extend or improve the economic useful life of existing assets are capitalized and amortized over the shorter of the estimated useful life of the acquired asset or the remaining life of the existing asset. We review our estimates of the costs of complying with environmental laws related to remediation and cleanup of various sites, including sites in which governmental agencies have designated us as a potentially responsible party (PRP). When it is probable that a loss will be incurred and where a range of the loss can be reasonably estimated, the best estimate within the range is accrued. When the best estimate within the range cannot be determined, the low end of the range is accrued. Potential insurance reimbursements are not offset against potential liabilities. As of March 30, 2019, we have been designated by the U.S. Environmental Protection Agency (EPA) and/or other responsible state agencies as a 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 these 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. 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, our 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. The activity for the three months ended March 30, 2019 related to our environmental liabilities was as follows: (In millions) Balance at December 29, 2018 $ 20.0 Charges, net of reversals .7 Payments (1.1) Balance at March 30, 2019 $ 19.6 Approximately $4 million and $5 million, respectively, of the balance was classified as short-term and included in Other current liabilities in the unaudited Condensed Consolidated Balance Sheets as of March 30, 2019 and December 29, 2018.
