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 qualitative and quantitative disclosures regarding certain climate-related topics on an annual basis. As a result of ongoing litigation, the SEC issued an order in April 2024 to stay the effectiveness of the rules during judicial review in a U.S. court. The SEC announced that it withdrew its defense of the rules in March 2025; however, the rules have not been formally rescinded and judicial proceedings are continuing.

The outcome of judicial proceedings remains uncertain. We will continue to monitor the status of the rules, which could be effective for us beginning in fiscal year 2026. If the rules are not overturned or rescinded and take effect on schedule, prospective adoption will be permitted with phased-in compliance beginning with our Annual Report on Form 10-K for the fiscal year ending 30 September 2026. We are evaluating the impact these rules may have on our disclosures.

Reportable Segment Disclosures

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures". We will adopt the update upon its effective date, which applies to our Annual Report on Form 10-K for the fiscal year ending 30 September 2025 and Forms 10-Q for interim periods thereafter. Upon adoption, we will expand our segment financial information disclosures to include significant expense categories that are regularly provided to our chief operating decision maker as well as other segment items reflected in the reported measure of segment profit or loss. Historical periods provided in the affected reports will be recast to conform to the amended presentation.

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.
