Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Environmental Matters The Company records liabilities for environmental matters when remedial efforts or damage claim payments are probable and the costs can be reasonably estimated. Such liabilities are based on the Company’s best estimate of the undiscounted future costs required to complete the remedial work. The recorded liabilities are adjusted periodically as remediation efforts progress or as additional technical, regulatory, or legal information becomes available. Given the uncertainties regarding the status of laws, regulations, enforcement policies, the impact of other potentially responsible parties, technology, and information related to individual sites, the Company does not believe it is possible to develop an estimate of the range of reasonably possible environmental loss in excess of the Company’s recorded liabilities. Costs related to environmental remediation are charged to expense in the period that the associated liability is accrued. The following table summarizes information concerning the Company’s recorded liabilities for environmental costs:

The Company does not currently possess sufficient information to reasonably estimate the amounts of environmental liabilities to be recorded upon future completion of studies, litigation, or settlements, and neither the timing nor the amount of the ultimate costs associated with environmental matters can be determined, although they could be material to the Company’s consolidated results of operations and operating cash flows in the periods recognized or paid. However, considering the Company’s past experience and existing reserves, the Company does not expect that environmental matters will have a material adverse effect on its consolidated financial position. Asset Retirement Obligations Asset retirement obligations result from legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and/or the normal operation of a long-lived asset. Accordingly, the Company recognizes asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The Company depreciates the amount added to property, plant and equipment on a straight-line basis, and recognizes accretion expense in connection with the discounted liability over the remaining useful life of the asset. The Company recognized as a liability the present value of the estimated future costs to decommission its uranium conversion facility. The estimated liability is based on the estimated useful lives of the underlying asset, third-party estimates of the cost to decommission the asset in the future, and federal and state regulatory requirements, adjusted for inflation and discounted using the Company’s credit-adjusted risk-free rate that ranges from 6.5% to 6.6%. Revisions to the liability could occur due to changes in the Company’s estimated useful lives of the underlying assets, estimated dates of decommissioning and timing of related cash outflows, changes in decommissioning costs, changes in federal or state regulatory guidance on the decommissioning of such facilities, or other changes in estimates. The Company recognizes changes due to revised estimates by adjusting the carrying amount of the liability and the related long-lived asset if the asset is still in service or charged to expense in the period if the asset is no longer in service. Other Matters Nuclear Facility matters Since 2018, the Company has been involved in various legal proceedings in the United States District Court for the Southern District of Illinois related to its Nuclear Facility, including eight separate lawsuits alleging cancer caused by radiation exposures that were settled in 2024. The Company remains involved in additional legal proceedings (i) related to alleged radiation contamination of properties around the plant by the city of Metropolis, Illinois, and the county of Massac, Illinois, (ii) a class action lawsuit alleging property damage by a group of plaintiffs on behalf of all property owners within a three-mile radius of the facility, and (iii) one alleged personal injury case. The Company is currently awaiting rulings on a motion for summary judgment related to the city and county cases, with rulings expected in 2026. For the alleged class action, the parties completed briefing on the plaintiffs’ motion for class certification and a ruling is expected in 2026. All plaintiffs in these matters are seeking compensatory damages and, in certain cases, punitive damages, medical monitoring, declaratory and/or injunctive relief. The Department of Energy (“the DoE”) has reached an agreement with the Company pursuant to which we understand the DoE intends to take appropriate action to provide sufficient assurance of the continued operational availability of the Company’s Nuclear Facility to support the existing and future demand for uranium hexafluoride, including by extending reimbursement to the Company for certain litigation costs. In addition, the Company is also pursuing claims under Honeywell’s nuclear liability policies with American Nuclear Insurers. While we cannot predict the outcome of these matters, based on the facts currently known to us, we do not anticipate that these matters will have a material adverse effect on our financial condition, results of operations, or cash flows. Under the Company’s agreement with the DoE, the DoE has also agreed to share in certain costs in connection with the expansion of our Nuclear Facility. Other matters The Company is subject to a number of other lawsuits, investigations, and disputes (some of which involve substantial amounts claimed) arising out of the conduct of the Company's business, including matters relating to commercial transactions, intellectual property, and environmental, health, and safety matters. The Company recognizes liabilities for any contingency that is probable of occurrence and reasonably estimable. The Company continually assesses the likelihood of adverse judgments or outcomes in such matters, as well as potential ranges of probable losses (taking into consideration any insurance recoveries), based on a careful analysis of each matter with the assistance of outside legal counsel and, if applicable, other experts. Given the uncertainty inherent in litigation and investigations, the Company cannot predict when or how these matters will be resolved and does not believe it is possible to develop estimates of reasonably possible loss (or a range of possible loss) in excess of current accruals for commitment and contingency matters. Considering the Company's past experience and existing accruals, the Company does not expect the outcome of such matters, either individually or in the aggregate, to have a material adverse effect on the Company's consolidated financial position. Because most contingencies are resolved over long periods of time, potential liabilities are subject to change due to new developments (including new discovery of facts, changes in legislation, and outcomes of similar cases through the judicial system) or changes in assumptions, which could cause the Company to pay damage awards or settlements (or become subject to equitable remedies) that could have a material adverse effect on the Company's consolidated results of operations or operating cash flows in the periods recognized or paid.
