Litigation	Litigation Climate Change Governmental and other plaintiffs in various jurisdictions across the United States have brought legal proceedings against fossil fuel producing companies, including Chevron entities, purporting to seek legal and equitable relief to address alleged impacts of climate change.

However, because of the uncertainties associated with ongoing litigation, we are unable to estimate the range of reasonably possible loss that may be attributable to liabilities, if any, in excess of the amount accrued. While the company believes the jury verdict is not legally or factually supported and intends to appeal and vigorously pursue post-judgment remedies, there can be no assurances that such defense efforts will be successful. To the extent the company is required to pay remediation damages in these cases, it may have a material adverse effect on our financial position and results of operations. Management believes that the claims in these lawsuits lack legal and factual merit and will continue to vigorously defend against such proceedings.
