In November 2023, the FASB issued ASU 2023-07, “Segment Reporting,” which provides improvements to reportable segment disclosures, primarily through enhanced disclosures about significant segment expenses. The standard became effective for us for fiscal years beginning after December 15, 2023 and is effective for interim periods within fiscal years beginning after December 15, 2024. Refer to Note 11.
In December 2023, the FASB issued ASU 2023-09, “Income Taxes,” which provides improvements to annual income tax disclosures by enhancing the transparency and decision usefulness of the material provided. The standard is effective for us for fiscal years beginning after December 15, 2024 on a prospective basis. Refer to the Income Taxes disclosure in Note 3.
In November 2024, the FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures,” to improve the disclosures about a public business entity’s expenses by providing more detailed information about the types of expenses in commonly presented expense captions. The standard will be effective for us for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. We are currently evaluating the impact that the adoption of this new standard will have on our consolidated financial statements and footnotes.
In December 2025, the FASB issued ASU 2025-11, “Interim Reporting,” which is intended to improve the navigability of the required interim reporting disclosures and clarifies when that guidance is applicable. The amendments in the ASU will be effective for us for interim reporting periods within annual reporting periods beginning after December 15, 2027. We are currently evaluating the impact that the adoption of these amendments will have on our footnotes.

About New Standards Disclosures
New accounting standards disclosures describe recently adopted pronouncements and those not yet effective, along with management's assessment of their expected impact. This section provides an early warning system for upcoming changes to how a company reports its financial results, often years before the new rules take effect.
Key signals: when management describes a not-yet-adopted standard's impact as "material" or "still being evaluated," it signals potential significant changes to reported metrics upon adoption. Watch for standards that affect a company's core operations — for example, revenue recognition changes for software companies or lease accounting changes for retailers with large store footprints. The transition method chosen (full retrospective versus modified retrospective) affects comparability with prior periods. Companies that delay adoption to the latest permitted date may be struggling with implementation complexity. Compare the disclosed impact assessments against peers in the same industry to gauge whether management's expectations are reasonable.
