This ASU is effective for all companies for fiscal years beginning after December 15, 2022, including interim periods within those years, and requires retrospective adoption. The Company adopted the required disclosures of this standard on a retrospective basis beginning with its first quarter ending November 18, 2023.

Refer to “Note F – Supplier Financing Programs.” Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280). The amendments in this ASU require disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (CODM), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss. This ASU requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss. Public entities will be required to provide all annual disclosures currently required by Topic 280 in interim periods, and entities with a single reportable segment are required to provide all the disclosures required by the amendments in the update and existing segment disclosures in Topic 280. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective adoption. Early adoption is permitted. The Company will adopt this standard beginning with our fiscal year ending August 30, 2025. The Company is currently evaluating these new disclosure requirements and does not expect the adoption to have a material impact.
