The Company’s environmental liabilities balance changed as follows during the three months ended April 1, 2023:
Balance at December 31, 2022
$170,681 
Increase in liabilities960 
Payments(1,452)
Foreign currency adjustments(14)
Balance at April 1, 2023
170,175 
Less: current portion(10,731)
Non-current environmental liabilities$159,444 
In addition to these estimated liabilities, the Company is subject to the risk of reasonably possible additional liabilities in excess of the established reserves due to potential changes in circumstances and future events, including, without limitation, changes to current laws and regulations; changes in governmental agency personnel, direction, philosophy or enforcement policies; developments in remediation technologies; increases in the cost of remediation, operation, maintenance and monitoring of its environmental liability; changes in the volume, nature or extent of contamination to be remediated or monitoring to be undertaken; the outcome of negotiations with governmental agencies or non-governmental parties; and changes in accounting rules or interpretations. Based on information available as of April 1, 2023, the Company estimates this exposure could range up to approximately $85 million, although no assurances can be given that this amount will not be exceeded given the factors described above. These potential additional costs are attributable to several sites and other applicable liabilities. This estimate excludes liabilities that would otherwise be considered reasonably possible but for the fact that they are not currently estimable, primarily due to the factors discussed above.
Subject to the previous paragraph, the Company believes its estimates of liabilities are sufficient for probable costs expected to be incurred over the next 20 years with respect to its environmental liabilities. However, no assurances are given that these estimates will be sufficient for the reasons described above and additional liabilities could have a material adverse effect on the Company’s financial position, results of operations and cash flows.
