SunCoke Energy Inc

7. Commitments and Contingent Liabilities

Legal Matters

The Company is a party to certain pending and threatened claims, including matters related to commercial disputes, employment claims, personal injury claims, common law tort claims, and environmental claims. Although the ultimate outcome of these claims cannot be ascertained at this time, it is reasonably possible that some portion of these claims could be resolved unfavorably to the Company. Management of the Company believes that any liability which may arise from these claims would likely not have a material adverse impact on our consolidated financial statements. SunCoke's threshold for disclosing material environmental legal proceedings involving a government authority where potential monetary sanctions are involved is $1 million.

Black Lung Benefit Liabilities

The Company has obligations related to coal workers’ pneumoconiosis, or black lung, to provide benefits to certain of its former coal miners and their dependents. Such benefits are provided for under Title IV of the Federal Coal Mine and Safety Act of 1969 and subsequent amendments, as well as for black lung benefits provided in the states of Virginia, Kentucky and West Virginia pursuant to workers’ compensation legislation. The Patient Protection and Affordable Care Act, which was implemented in 2010 and amended previous legislation related to coal workers’ black lung obligations, provides for the automatic extension of awarded lifetime benefits to surviving spouses and changes the legal criteria used to assess and award claims.

We adjust our liability each year based upon actuarial calculations of our expected future payments for these benefits. Our independent actuarial consultants calculate the present value of the estimated black lung liability annually in the fourth quarter, unless there are changes in facts and circumstances that could materially alter the amount of the liability, based on actuarial models utilizing our population of former coal miners, historical payout patterns of both the Company and the industry, expected claim filing patterns, expected claimant success rates, actuarial mortality rates, medical costs, death benefits, dependents, discount rates and the current federally mandated payout rates. The estimated liability may be impacted by future changes in the statutory mechanisms, modifications by court decisions and changes in filing patterns by claimants and their advisors, the impact of which cannot be estimated. Refer to Note 12 in our Annual Report on Form 10-K for the year ended December 31, 2023 for further detail on the valuation of our black lung benefit liability.

On February 1, 2013, SunCoke obtained commercial insurance for black lung claims in excess of a deductible for employees with a last date of employment after that date. Also during 2013, we were reauthorized to continue to self-insure black lung liabilities incurred prior to February 1, 2013 by the U.S. Department of Labor's Division of Coal Mine Workers' Compensation (“DCMWC”) in exchange for $8.4 million of collateral. In July 2019, the DCMWC required that SunCoke, along with a number of other companies, file an application and supporting documentation for reauthorization to self-insure any legacy black lung obligations incurred prior to February 1, 2013. The Company provided the requested information in the fourth quarter of 2019. The DCMWC subsequently notified the Company in a letter dated February 21, 2020 that the Company was reauthorized to self-insure certain of its black lung obligations; however, the reauthorization is contingent upon the Company providing collateral of $40.4 million to secure certain of its black lung obligations. This proposed collateral requirement is a substantial increase from the $8.4 million in collateral that the Company currently provides to secure these self-insured black lung obligations. The reauthorization process provided the Company with the right to appeal the security determination. SunCoke exercised its right to appeal the DCMWC’s security determination and provided additional information supporting the Company’s position in May 2020 and February 2021. If the Company’s appeal is unsuccessful, the Company may be required to provide additional collateral to receive the self-insurance reauthorization from the DCMWC, which could potentially reduce the Company’s liquidity. Additionally, on January 19, 2023, the Department of Labor issued a new proposed rule that would require self-insured companies to post collateral in the amount of 120 percent of the company's total expected lifetime black lung obligations as determined by the DCMWC. While this new proposed rule is not effective, if finalized, it could potentially reduce the Company's liquidity. We submitted comments on this proposed rule and will continue to monitor any impact to the Company.
