Commitments and Contingencies Disclosure [Abstract] |
Commitments, Contingencies and Guarantees | (3) Comm itments, Contingencies and Guarantees There have been no significant changes to commitments, contingencies and guarantees from those previously disclosed in Note 3 of our Notes to the Consolidated Financial Statements in our 2024 Annual Report on Form 10-K except as described below. Transfers of Renewable Tax Credits In January 2025, we entered into an agreement with a third party to sell our 2024 generated PTCs. In the agreement, we provided indemnifications associated with the proceeds for PTCs transferred to the third party in the event of an adverse change or interpretation of tax law, including whether the related tax credits meet the qualification requirements. We believe the likelihood of having to make any material cash payments under these indemnifications is remote. See Note 11 for additional information. Manufactured Gas Plant In 2008, we acquired liabilities for a former manufactured gas plant site in Iowa, which was previously used to convert coal to natural gas. The acquisition provided for an insurance recovery, which was used to help offset remediation costs. Our insurance recovery asset was valued at $1.5 million as of September 30, 2025, and was recorded in Other current assets on our Consolidated Balance Sheets. We recovered our insurance recovery asset in October 2025. A s of December 31, 2024, we had an Accrued liability of $9.7 million on our Consolidated Balance Sheets for the remaining remediation of the manufactured gas plant site in Iowa. During the nine months ended September 30, 2025, we completed substantially all remaining remediation work. As of September 30, 2025, $11.5 million of cumulative remediation costs, which are net of our $1.5 million insurance recovery asset, were recorded to a Regulatory asset on our Consolidated Balance Sheets. Iowa Gas intends to seek recovery of this $11.5 million regulatory asset during a future rate review. Deborah Ferrari et al. v. Colorado Electric, Case No. 2024CV31889 (District Court for the City and County of Denver, Colorado) Colorado Electric is currently involved in a legal matter related to an auto accident that could result in a liability. While we have determined that liability is probable, we believe Colorado Electric has meritorious defenses regarding the damages claimed and are vigorously defending its position. As such, the outcome of this matter remains uncertain. At this time, we are unable to estimate the possible range of liability due to the complexity of the issues involved and the status of the proceedings. Accordingly, to date, we have not recorded an accrual in the financial statements. We will continue to monitor the matter and will accrue a liability if and when it becomes reasonably estimable. At the time of the accident, the Company maintained an insurance policy designed to provide coverage for certain legal and regulatory exposures. In the event we incur a liability related to this legal matter, we will seek recovery under this insurance policy. GT Resources, LLC v. Black Hills Corporation, Case No. 2020CV30751 (District Court for the City and County of Denver, Colorado) On April 13, 2022, a jury awarded $41 million for claims made by GT Resources, LLC (“GTR”) against BHC and two of its subsidiaries (Black Hills Exploration and Production, Inc. and Black Hills Gas Resources, Inc.), which ceased oil and natural gas operations in 2018 as part of BHC’s decision to exit the exploration and production business. The claims involved a dispute over a 2.3 million-acre concession award in Costa Rica which was acquired by a BHC subsidiary in 2003. GTR retained rights to receive a royalty interest on any hydrocarbon production from the concession upon the occurrence of contingent events. GTR contended that BHC and its subsidiaries failed to adequately pursue the opportunity and failed to transfer the concession to GTR. We appealed this verdict to the Colorado Court of Appeals. On October 19, 2023, the Appellate Court reversed and remanded the case with directions limiting any retrial to the narrow issue of whether there was improper interference with the prospective conveyance of the concession. The retrial occurred and on May 12, 2025, the jury returned a verdict in favor of BHC and its subsidiaries on all counts, thus resolving any claims without material impact on our financial position, results or operations and cash flows.
