Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies Disclosure | COMMITMENTS AND CONTINGENCIES A summary of the Company's commitments and contingencies can be found in Note 15 to the Consolidated Financial Statements included in the 2022 10-K, which is incorporated by reference herein. Environmental Matters Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. At September 30, 2023, the Company had accrued obligations of $1,228 million for probable environmental remediation and restoration costs ($1,192 million at December 31, 2022), including $258 million for the remediation of Superfund sites ($244 million at December 31, 2022). This is management’s best estimate of the costs for remediation and restoration with respect to environmental matters for which the Company has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to approximately two times that amount. Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material impact on the Company's results of operations, financial condition and cash flows. It is the opinion of the Company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material impact on the Company’s results of operations, financial condition and cash flows. Inherent uncertainties exist in these estimates primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. As new or additional information becomes available and/or certain spending trends become known, management will evaluate such information in determination of the current estimate of environmental liability. Litigation Asbestos-Related Matters of Union Carbide Corporation Each quarter, Union Carbide reviews asbestos-related claims filed, settled and dismissed, as well as average settlement and resolution costs by disease category. Union Carbide also considers additional quantitative and qualitative factors such as the nature of pending claims, trial experience of Union Carbide and other asbestos defendants, current spending for defense and processing costs, significant appellate rulings and legislative developments, trends in the tort system, and their respective effects on expected future resolution costs. Union Carbide's management considers these factors in conjunction with the most recent actuarial study and determines whether a change in the estimate is warranted. Based on Union Carbide's review of 2023 activity, it was determined that no adjustment to the accrual was required at September 30, 2023. Union Carbide’s total asbestos-related liability for pending and future claims and defense and processing costs was $884 million at September 30, 2023 ($947 million at December 31, 2022). At September 30, 2023, approximately 23 percent of the recorded claim liability related to pending claims and approximately 77 percent related to future claims. Groundwater Contamination The Company is the subject of various complaints related to alleged groundwater contamination based on decades-old sales and applications of certain agricultural chemical products ("Legacy Liabilities"). The costs associated with these Legacy Liabilities were previously covered by insurance policies that have since been depleted. In the first quarter of 2023, the Company completed a study of the Legacy Liabilities now deemed to be probable and estimable based on the public reporting of sampling data and historical information to develop a reasonable estimate of the cost of pending and future claims. As a result, the Company recorded a pretax charge of $177 million, included in "Cost of sales" in the consolidated statements of income and related to Industrial Intermediates & Infrastructure. At September 30, 2023, the total liability related to such alleged Legacy Liabilities settlements was $234 million, which was included in “Accrued and other current liabilities” and "Other noncurrent obligations" in the consolidated balance sheets. Indemnifications with Corning Incorporated The Company had indemnification assets with Corning Incorporated of $114 million at September 30, 2023 ($98 million at December 31, 2022) related to the 2016 ownership restructure of Dow Silicones, which were included in "Other current assets" and "Noncurrent receivables" in the consolidated balance sheets. Gain Contingency - Dow v. Nova Chemicals Corporation Ethylene Asset Matter As a result of a 2019 damages judgment related to the ethylene asset matter, Nova was ordered to pay the Company $1.43 billion Canadian dollars (equivalent to approximately $1.08 billion U.S. dollars), for which the Company received payment in October 2019 and March 2020. At September 30, 2023, $323 million ($323 million at December 31, 2022) was included in "Other noncurrent obligations" in the Company's consolidated balance sheets related to the disputed portion of the damages judgment.
