Standards that are not yet adopted as of June 30, 2026
ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax DisclosuresThis ASU enhances income tax disclosure requirements. Under the ASU, public business entities must annually (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). Specific categories that must be included in the reconciliation for each annual reporting period are specified in the amendment. This update is effective for annual periods beginning after December 15, 2024. Early adoption of the amendments is permitted. Upon adoption, the amendments shall be applied on a prospective basis. Retrospective application is permitted.September 30, 2026We plan to adopt this ASU, as required, during fiscal year 2026, with the first disclosure enhancements reflected in our fiscal year 2026 Form 10-K. We are currently evaluating the impact this ASU will have on our disclosures.
ASU No. 2024-03, Income Statement -- Reporting Comprehensive Income -- Expense Disaggregation Disclosure (Subtopic 220-40)This ASU enhances disclosure requirements for certain costs and expenses. The amendments in this update enhance annual and interim disclosure requirements, certain liability-related expenses, expense reimbursements related to a cost-sharing or cost-reimbursement arrangement with another entity, and the disaggregation of relevant expense captions. This update gives entities the ability to use estimates or other methods that produce a reasonable approximation of the amounts required to be disclosed. This update is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. Upon adoption, the amendments shall be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this Update or (2) retrospectively to any or all prior periods presented in the financial statements.September 30, 2028We plan to adopt this ASU, as required, during fiscal year 2028 with the first disclosure enhancements reflected in our 2028 fiscal year Form 10-K. We are currently evaluating the impact the new guidance may have on our consolidated financial statements and disclosures.
