Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and principal accounting policies	Organization and principal accounting policies Signet Jewelers Limited (“Signet” or the “Company”), a holding company incorporated in Bermuda, is the world’s largest retailer of diamond jewelry. The Company operates through its 100% owned subsidiaries with sales primarily in the United States (“US”), United Kingdom (“UK”) and Canada. Signet manages its business as three reportable segments: North America, International, and Other. The “Other” reportable segment primarily consists of subsidiaries involved in the purchasing and conversion of rough diamonds to polished stones. See Note 5 for additional discussion of the Company’s reportable segments. Signet’s business is seasonal, with the fourth quarter historically accounting for approximately 35-40% of annual sales as well as for a substantial portion of the annual operating profit. Basis of preparation The condensed consolidated financial statements of Signet 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. Signet 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 January 28, 2023 filed with the SEC on March 16, 2023. 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 The Company’s fiscal year ends on the Saturday nearest to January 31st. Fiscal 2024 and Fiscal 2023 refer to the 53-week period ending February 3, 2024 and the 52-week period ended January 28, 2023, respectively. Within these condensed consolidated financial statements, the third quarter and year to date periods of the relevant fiscal years 2024 and 2023 refer to the 13 and 39 weeks ended October 28, 2023 and October 29, 2022, respectively. 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 income (expense) within the condensed consolidated statements of operations. See Note 9 for additional information regarding the Company’s foreign currency translation.
