Unaudited Condensed Consolidated Financial Statements	Jun. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Unaudited Condensed Consolidated Financial Statements	Unaudited Condensed Consolidated Financial Statements We prepared the accompanying condensed consolidated financial statements of Valaris Limited and its subsidiaries (the "Company," "Valaris," "our," "we" or "us") in accordance with accounting principles generally accepted in the United States of America ("GAAP"), pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") included in the instructions to Form 10-Q and Article 10 of Regulation S-X. The financial information included in this report is unaudited but, in our opinion, includes all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods presented. The December 31, 2023 Condensed Consolidated Balance Sheet data was derived from our 2023 audited consolidated financial statements but does not include all disclosures required by GAAP. The preparation of our condensed consolidated financial statements requires us to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures of gain and loss contingencies as of the date of the financial statements. Actual results could differ from those estimates. Results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2024, or for any future period. We recommend these condensed consolidated financial statements be read in conjunction with our annual report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 22, 2024 (our "Annual Report"). Summary of Significant Accounting Policies Please refer to "Note 1. Description of the Business and Summary of Significant Accounting Policies" of our Consolidated Financial Statements from our Annual Report for the discussion of our significant accounting policies. Certain previously reported amounts have been reclassified to conform to the current year presentation. New Accounting Pronouncements Accounting pronouncements to be adopted Improvements to Reportable Segment Disclosures - In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("Update 2023-07"), which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in Update 2023-07 require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker ("CODM"), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. Annual disclosures are required for fiscal years beginning after December 15, 2023 and interim disclosures are required for periods within fiscal years beginning after December 15, 2024. Retrospective application is required for all prior periods presented, and early adoption is permitted. We will adopt Update 2023-07 in the period required and while it will require us to expand certain disclosures within the notes to our condensed consolidated financial statements, we do not expect the adoption to have a material impact on our consolidated financial position, operating results and cash flows. Improvements to Income Tax Disclosures - In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("Update 2023-09"), which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates as well as additional disaggregation of taxes paid. The amendments in Update 2023-09 also remove disclosures related to certain unrecognized tax benefits and deferred taxes. Update 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The amendments are required to be applied on a prospective basis, with an option to apply the guidance retrospectively. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures. With the exception of the updated standards discussed above, there have been no accounting pronouncements issued and not yet effective that have significance, or potential significance, to our condensed consolidated financial statements.
