New Accounting Guidance

NEW ACCOUNTING GUIDANCE

Accounting Guidance Implemented in Fiscal Year 2025

Reportable Segment Disclosures

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures". We adopted the update upon its effective date in fiscal year 2025 and implemented the expanded disclosure requirements in Note 26, Business Segment and Geographic Information, of this Annual Report on Form 10-K.

Pursuant to the update, we expanded our disclosures to include significant expense categories that are regularly provided to our Chief Operating Decision Maker, as well as other segment items included in the reported measure of segment profit or loss. Prior period segment disclosures presented in this report have been updated to reflect the additional information now required under the new guidance.

These updates will also be reflected in our Quarterly Reports on Form 10-Q beginning with the first quarter of fiscal year 2026.

New Accounting Guidance to be Implemented

Climate-Related Disclosures

In March 2024, the SEC issued Release No. 33-11275, "The Enhancement and Standardization of Climate-Related Disclosures for Investors", which includes final rules for providing annual qualitative and quantitative disclosures regarding certain climate-related topics. As a result of legal challenges, the SEC issued an order in April 2024 to stay the effectiveness of the rules pending the completion of judicial review of the consolidated challenges before the United States Court of Appeals for the Eighth Circuit.

The SEC subsequently announced its withdrawal of its legal defense to such challenges in March 2025; however, the rules have not been formally rescinded by the SEC. In April 2025, the appellate court suspended its proceedings indefinitely and directed the SEC to file a status report outlining its next steps. In response, the SEC stated in July 2025 that it does not intend to revisit the rules and requested the court to rule on the pending petitions.

In September 2025, the appellate court declined the SEC's request and placed the litigation in abeyance, which will remain in effect until the SEC reconsiders the rules by notice-and-comment rulemaking or renews its defense. We continue to monitor these developments.

Income Tax Disclosures

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740)—Improvements to Income Tax Disclosures”, to expand income tax disclosures, primarily through disaggregation requirements for the rate reconciliation and income taxes paid. The update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2026, although early adoption is permitted. The amendments should be applied on a prospective basis with a retrospective option. We are evaluating the impact this update will have on our disclosures.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires additional disclosures of certain costs and expenses, including purchases of inventory, employee compensation, depreciation, intangible asset amortization, as well as selling expenses in the notes to the financial statements. In January 2025, the FASB clarified that the update will be effective in our Annual Report on Form 10-K for the fiscal year ending 30 September 2028 as well as interim periods thereafter, although early adoption is permitted. The amendments should be applied either prospectively after the effective date or retrospectively to any or all periods presented. We are evaluating the impact this update will have on our disclosures.

Measurement of Credit Losses for Accounts Receivable and Contract Assets

In July 2025, the FASB issued ASU 2025-09, “Measurement of Credit Losses for Accounts Receivable and Contract Assets”, which allows an entity to elect a practical expedient to assume that current conditions as of the balance sheet date do not change when estimating expected credit losses. This update will be effective at the beginning of fiscal year 2027, although early adoption is permitted. The amendments should be applied on a prospective basis. We are evaluating the implications of this update. At this time, we do not expect it will have a material impact on our financial statements.

Accounting for Internal-Use Software

In September 2025, the FASB issued ASU 2025-06, “Targeted Improvements to the Accounting for Internal-Use Software”, which establishes criteria for commencing cost capitalization for software projects. This update will be effective at the beginning of fiscal year 2029, although early adoption is permitted. The amendments can be applied prospectively, retrospectively, or via a modified prospective transition method. We are evaluating the impact this update will have on our financial statements.
