Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The interim consolidated financial statements of Air Products and Chemicals, Inc. and its subsidiaries included herein have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to such rules and regulations. In our opinion, the accompanying statements reflect adjustments necessary to fairly present the financial position, results of operations, and cash flows for those periods indicated and contain adequate disclosures to make the information presented not misleading. Adjustments included herein are of a normal, recurring nature unless otherwise disclosed in the notes to the interim consolidated financial statements. To fully understand the basis of presentation, the interim consolidated financial statements and related notes included herein should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended 30 September 2024 (the "2024 Form 10-K"), which was filed with the SEC on 21 November 2024. Results of operations for interim periods are not necessarily indicative of the results of operations for a full year.
Use of Estimates, Policy | Estimates and Assumptions Preparation of the interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in these statements and the accompanying notes. Actual results could differ from those estimates.
New Accounting Guidance to be Implemented | 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 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. We continue to monitor these developments. 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.
