Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies ARO Newbuild Funding Obligations In connection with our 50/50 unconsolidated joint venture, we have a potential obligation to fund ARO for newbuild jackup rigs. The Shareholder Agreement specifies that ARO shall purchase 20 newbuild jackup rigs. The joint venture partners intend for the newbuild jackup rigs to be financed out of available cash on hand and from ARO's operations and/or funds available from third-party financing. The first two newbuild jackups, Kingdom 1 and Kingdom 2, were delivered and commenced operations in 2023 and 2024, respectively. In October 2024 and November 2025, ARO ordered the third and fourth newbuild jackups, Kingdom 3 and Kingdom 4, respectively, for a purchase price of approximately $300.0 million each. ARO paid a 25% down payment from cash on hand for Kingdom 3 and Kingdom 4. The final payment for each rig will be due upon delivery. In the event ARO has insufficient cash or is unable to obtain third-party financing, each partner may periodically be required to make additional capital contributions to ARO, up to a maximum aggregate contribution of $1.25 billion from each partner to fund the newbuild program. Beginning with the delivery of the second newbuild, each partner's commitment is reduced by the lesser of the actual cost of each newbuild rig or $250.0 million, on a proportionate basis. Following the delivery of Kingdom 2, our commitment to fund the newbuild program has been reduced to $1.1 billion. Letters of Credit and Surety Bonds In the ordinary course of business with customers and others, we have entered into letters of credit and surety bonds to guarantee our performance as it relates to our drilling contracts, contract bidding, customs duties, tax appeals and other obligations in various jurisdictions. Letters of credit and surety bonds outstanding as of June 30, 2026 totaled $111.4 million and are issued under facilities provided by various banks and other financial institutions, but none were issued under the 2028 Credit Agreement. Obligations under these letters of credit and surety bonds are not normally called, as we typically comply with the underlying performance requirements. As of June 30, 2026, we had collateral deposits in the amount of $15.1 million with respect to these agreements. Other Matters In addition to the foregoing, we are named defendants or parties in certain other lawsuits, claims or proceedings incidental to our business and are involved from time to time as parties to governmental investigations or proceedings, including matters related to taxation, arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we do not expect these matters to have a material adverse effect on our financial position, operating results and cash flows.
