Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of preparation | 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”) have been condensed or omitted from this report, as is permitted by such rules and regulations. 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. It is suggested that these condensed consolidated financial statements 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 2, 2019 filed with the SEC on April 3, 2019. Signet has reclassified certain prior year amounts in its consolidated financial statements and notes to the consolidated financial statements to conform to the current year presentation.
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 reporting period. Actual results could differ from those estimates. Estimates and assumptions are primarily made in relation to the valuation of accounts receivable, inventories, deferred revenue, derivatives, employee benefits, income taxes, contingencies, asset impairments, leases, indefinite-lived intangible assets, depreciation and amortization of long-lived assets, as well as accounting for business combinations.
Fiscal year | Fiscal year The Company’s fiscal year ends on the Saturday nearest to January 31 st. Fiscal 2020 and Fiscal 2019 refer to the 52 week periods ending February 1, 2020 and February 2, 2019, respectively. Within these condensed consolidated financial statements, the second quarter of the relevant fiscal years 2020 and 2019 refer to the 13 weeks ended August 3, 2019 and August 4, 2018, respectively.
Foreign currency transactions | 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 segment and Canada as part of the North America segment, are consolidated using the local currency as the functional currency. Assets and liabilities are translated at the rates of exchange on the balance sheet date, 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 equity as a component of accumulated other comprehensive income (loss) (“AOCI”). Gains or losses resulting from foreign currency transactions are included within the condensed consolidated statements of operations.
New accounting pronouncements | New accounting pronouncements to be adopted in future periods The Company is currently evaluating the impact on its financial statements of the following ASUs:
Standard |  | Description
ASU No. 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, issued August 2018. |  | Modifies the disclosure requirements on fair value measurements in Topic 820 and eliminates ‘at a minimum’ from the phrase ‘an entity shall disclose at a minimum’ to promote the appropriate exercise of discretion by entities when considering fair value disclosures and to clarify that materiality is an appropriate consideration. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted.
ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, issued August 2018. |  | Modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans and clarifies the disclosure requirements regarding projected benefit obligations and accumulated benefit obligations. The ASU is effective for fiscal years ending after December 15, 2020, with early adoption permitted.
