General information | General information Seadrill Limited (along with any one or more of its consolidated subsidiaries, or to all such entities, referred to as "Seadrill", "we", "us", "our", and "the Company") is incorporated in Bermuda. We are an offshore drilling contractor providing worldwide offshore drilling services to the oil and gas industry. Our primary business is the ownership and operation of drillships and semi-submersible rigs for operations in shallow to ultra-deepwater areas in both benign and harsh environments. We contract our drilling units to drill wells for our customers on a dayrate basis. Our customers include oil super-majors, state-owned national oil companies and independent oil and gas companies. In addition, we provide management services to certain affiliated entities. Basis of presentation The accompanying unaudited Condensed Consolidated Financial Statements of Seadrill Limited have been prepared in accordance with accounting principles generally accepted in the U.S. ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the SEC. Accordingly, pursuant to such rules and regulations, they do not include all disclosures required by U.S. GAAP for annual financial statements. In the opinion of management, the unaudited Condensed Consolidated Financial Statements includes all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of financial position, results of operations and cash flows for the interim periods. Results of operations for interim periods are not necessarily indicative of results of operations for the respective full years, or any future period. The accompanying unaudited Condensed Consolidated Financial Statements and related notes should be read in conjunction with our 2024 10-K. Certain reclassifications have been made to previously reported amounts to conform to the current period presentation. These reclassifications did not have a material effect on our unaudited Condensed Consolidated Financial Statements. Significant accounting policies Refer to Note 2 - "Accounting policies" of our Consolidated Financial Statements from our 2024 10-K for additional information related to our significant accounting policies.
