Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Note 10 — Commitments and Contingencies Tax Matters Audit claims of approximately $356.4 million at September 30, 2025, attributable to income and other business taxes remain outstanding and are under continued objection by Noble. Such audit claims are mostly attributable to Brazil and remain under continued monitoring and evaluation on a quarterly basis as facts change and as audits and/or litigation continue to progress. We intend to vigorously defend our reported positions and currently believe the ultimate resolution of the audit claims will not have a material adverse effect on our consolidated financial statements. We operate in numerous countries throughout the world and our tax returns filed in those jurisdictions are subject to review and examination by tax authorities within those jurisdictions. We recognize uncertain tax positions that we believe have a greater than 50% likelihood of being sustained upon challenge by a tax authority. We cannot predict or provide assurance as to the ultimate outcome of any existing or future assessments. Services Agreement In February 2016, Diamond entered into a ten-year agreement with a subsidiary of Baker Hughes Company (formerly named Baker Hughes, a GE company) to provide services with respect to certain blowout preventer and related well control equipment on our drillships. Such services include management of maintenance, certification, and reliability with respect to such equipment. On July 2, 2025, the services agreement was terminated for convenience. Noble and the services company have agreed on a purchase price of approximately $34.8 million for the capital and consumable spares, including other tooling equipment, to be paid before the end of 2025. Letters of Credit and Surety Bonds As of September 30, 2025, we had $18.0 million of letters of credit issued under the 2023 Revolving Credit Facility and an additional $149.7 million in letters of credit and surety bonds issued under bilateral arrangements which guarantee our performance as it relates to our drilling contracts, contract bidding, tax appeals, customs duties, and other obligations in various jurisdictions. We expect to comply with the underlying performance requirements and we expect obligations under these letters of credit and surety bonds will not be called. Other Contingencies We are a defendant in certain other claims and litigation arising out of operations in the ordinary course of business, including personal injury claims, the resolution of which, in the opinion of management, will not be material to our financial position, results of operations, or cash flows. There is inherent risk in any litigation or dispute and no assurance can be given as to the outcome of these claims.
