Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of preparation	Basis of preparation The condensed consolidated financial statements of the Company are prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with US generally accepted accounting principles (“US GAAP” or “GAAP”) have been condensed or omitted from this report, as is permitted by such rules and regulations. Intercompany transactions and balances have been eliminated in consolidation. The Company has reclassified certain prior year amounts to conform to the current year presentation. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results for the interim periods. The results for interim periods are not necessarily indicative of the results to be expected for the full fiscal year or for any other interim period. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in Signet’s Annual Report on Form 10-K for the fiscal year ended February 3, 2024 filed with the SEC on March 21, 2024.
Use of estimates	Use of estimates The preparation of these condensed consolidated financial statements, in conformity with US GAAP and SEC regulations for interim reporting, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenues and expenses during the reported periods. Actual results could differ from those estimates. Estimates and assumptions are primarily made in relation to the valuation of inventories, deferred revenue, employee compensation, income taxes, contingencies, leases, asset impairments for goodwill, indefinite-lived intangible and long-lived assets and the depreciation and amortization of long-lived assets.
Fiscal year	Fiscal year The Company’s fiscal year ends on the Saturday nearest to January 31st. Fiscal 2025 and Fiscal 2024 refer to the 52-week period ending February 1, 2025 and the 53-week period ended February 3, 2024, respectively. Within these condensed consolidated financial statements, the first quarter of the relevant fiscal years 2025 and 2024 refer to the 13 weeks ended May 4, 2024 and April 29, 2023, respectively.
Foreign currency translation	Foreign currency translation The financial position and operating results of certain foreign operations, including certain subsidiaries operating in the UK as part of the International reportable segment and Canada as part of the North America reportable segment, are consolidated using the local currency as the functional currency. Assets and liabilities are translated at the rates of exchange on the condensed consolidated balance sheet dates, and revenues and expenses are translated at the monthly average rates of exchange during the period. Resulting translation gains or losses are included in the accompanying condensed consolidated statements of shareholders’ equity as a component of accumulated other comprehensive income (loss) (“AOCI”). Gains or losses resulting from foreign currency transactions are included within other operating (expense) income, net within the condensed consolidated statements of operations. See Note 8 for additional information regarding the Company’s foreign currency translation.
New accounting pronouncements recently adopted and New accounting pronouncements issued but not yet adopted	New accounting pronouncements recently adopted There were no new accounting pronouncements adopted during Fiscal 2025 that have a material impact on the Company’s financial position or results of operations. New accounting pronouncements issued but not yet adopted Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”) In November 2023, the FASB issued ASU 2023-07. This ASU requires the following disclosures on an annual and interim basis: •Significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included with each reported measure of segment profit/loss. •Other segment items by reportable segment, consisting of differences between segment revenue and segment profit/loss not already disclosed above. •Other information by reportable segment, including total assets, depreciation and amortization, and capital expenditures. •The title of the CODM and an explanation of how the CODM uses the reported measures of segment profit/loss in assessing segment performance and deciding how to allocate resources. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted, and should be applied on a retrospective basis. This ASU will have no impact on the Company’s financial condition or results of operations. The Company is evaluating the impact of this ASU on its segment reporting disclosures. Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”) In December 2023, the FASB issued ASU 2023-09. This ASU modifies the annual disclosure requirements for income taxes in the following ways: •The effective tax rate reconciliation must be disclosed using both percentages and dollars (currently only one is required). The reconciliation must contain several prescriptive categories, including disaggregating material impacts from foreign, state, and local taxes by jurisdiction. Qualitative information regarding material reconciling items is also required to be disclosed. •The amount of income taxes paid must be disclosed and disaggregated by jurisdiction. The amendments in this ASU are effective for fiscal years beginning after December 15, 2024, with early adoption permitted, and may be applied on a prospective or retrospective basis. This ASU will have no impact on the Company’s financial condition or results of operations. The Company is evaluating the impact of this ASU on its income tax disclosures.
