Estimates of loss contingencies are based on various assumptions and judgments. Due to the numerous uncertainties and variables associated with these assumptions and judgments, both the precision and reliability of the resulting estimates are subject to substantial uncertainty. Estimated exposure to contingencies is regularly monitored, and as additional information becomes available, estimates may change significantly. Although no estimate of the range of any such change can be made at this time, the amount ultimately paid in connection with these matters could materially exceed, in either the near term or the longer term, the amounts accrued to date. Estimates of loss contingencies do not reflect potential future recoveries from insurance carriers, except to the extent that recovery is deemed probable based on an insurer’s agreement to payment terms. Environmental Matters A reserve is maintained for undiscounted estimated environmental loss contingencies. This reserve primarily covers estimated future costs for the remediation of hazardous or toxic substances at various sites currently or previously owned by the Company. Estimates of environmental loss contingencies are based on a range of assumptions and judgments, which vary depending on the specific facts and circumstances of each case. These estimates typically reflect management's assumptions regarding the probable nature, magnitude, and timing of required investigation, remediation, and/or monitoring activities, as well as the probable costs associated with those activities. In some cases, estimates also consider the obligation, willingness, or ability of third parties to bear a proportionate or allocated share of the costs. Due to the numerous uncertainties and variables associated with these assumptions and judgments-as well as the potential effects of changes in governmental regulations and environmental technologies-the precision and reliability of the resulting estimates are subject to substantial uncertainty. Estimated exposure to environmental loss contingencies is regularly monitored, and estimates may be revised significantly as additional information becomes available. Other Proceedings From time to time, the Company and its subsidiaries are parties to certain legal proceedings arising in our ordinary course of business. Based on currently available information, management does not believe that the resolution of such proceedings could reasonably be expected to have a material adverse effect on the Company's financial position, results of operations, cash flows, or liquidity.
