Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and contingencies Legal proceedings Employment practices In March 2008, a group of private plaintiffs (the “Claimants”) filed a class and collective action lawsuit for an unspecified amount against Sterling Jewelers, Inc. (“SJI”), a subsidiary of Signet, in the US District Court for the Southern District of New York (“SDNY”), alleging that US store-level employment practices as to compensation and promotions discriminate on the basis of gender in purported violation of Title VII of the Civil Rights Act of 1964 (“Title VII”) and the Equal Pay Act (“EPA”). In June 2008, the SDNY referred the matter to private arbitration with the American Arbitration Association (“AAA”) where the Claimants sought to proceed on a class-wide basis. On February 2, 2015, the arbitrator issued a Class Determination Award in which she certified a class (estimated to include approximately 70,000 class members at the time) for the Claimants’ disparate impact claims for declaratory and injunctive relief under Title VII. On February 29, 2016, the arbitrator granted Claimants’ Motion for Conditional Certification of Claimants’ EPA Claims and Authorization of Notice, and notice to EPA collective action members was issued on May 3, 2016. The opt-in period for the EPA collective action closed on August 1, 2016, and the number of valid opt-in EPA Claimants is believed to be approximately 9,124. SJL challenged the arbitrator’s Class Determination Award with the SDNY. Although the SDNY vacated the Class Determination Award on January 15, 2018, on appeal the US Court of Appeals for the Second Circuit (“Second Circuit”) held that the SDNY erred and remanded the case to the SDNY to decide whether the Arbitrator erred in certifying an opt-out, as opposed to a mandatory, class for declaratory and injunctive relief. On January 27, 2021 the SDNY ordered the case remanded to the AAA for further proceedings in arbitration on a class-wide basis. Subsequently, the arbitrator retired, and the parties selected a new arbitrator to oversee the proceedings moving forward. On October 8, 2021, the newly selected arbitrator issued an amended case management plan and scheduled the arbitration hearing to begin on September 5, 2022. SJI denies the allegations of the Claimants and has been defending the case vigorously. On June 8, 2022, SJI and the Claimants reached a settlement agreement, which was subject to preliminary and final approval after notice to the class. The settlement provides for the dismissal of the arbitration with prejudice and includes payments by the Company totaling approximately $175 million. As a result of the settlement, the Company recorded a pre-tax charge of $190 million within other operating expense in the condensed consolidated statement of operations during the first quarter ended April 30, 2022. This settlement charge included the payments to the Claimants, estimated employer payroll taxes, class administration fees and Claimants’ counsel attorney fees and costs. The arbitrator issued a preliminary approval of the settlement agreement on June 23, 2022 and a final approval order on November 15, 2022. The parties sought the SDNY’s confirmation of the arbitrator’s final approval award, and on March 14, 2023, received the order confirming the award. Based on the final assessment of employer payroll taxes due, the final settlement amount was reduced to approximately $185 million, which was fully funded by the Company in the first quarter of Fiscal 2024. Previously settled matters In February 2023, the Company received an unfavorable ruling under a private arbitration involving a dispute with a vendor alleging breach of contract. The matter was heard before the International Centre for Dispute Resolution, a division of the AAA. As a result of this ruling, during the fourth quarter of Fiscal 2023, the Company recorded a pre-tax charge of $15.9 million within other operating income (expense) in the consolidated statement of operations. This was paid in March 2023.
