Consolidation, Noncontrolling Interests and Basis of Presentation	CONSOLIDATION, NONCONTROLLING INTERESTS AND BASIS OF PRESENTATION The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with Generally Accepted Accounting Principles in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q. In our opinion, all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation have been included for the three- and six-month periods ended November 30, 2024 and 2023. For further information, refer to the Consolidated Financial Statements and Notes included in our Annual Report on Form 10-K for the year ended May 31, 2024. Our financial statements include all of our majority-owned subsidiaries. We account for our investments in less-than-majority-owned joint ventures, for which we have the ability to exercise significant influence, under the equity method. Effects of transactions between related companies are eliminated in consolidation. Noncontrolling interests are presented in our Consolidated Financial Statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in our Consolidated Financial Statements. Additionally, our Consolidated Financial Statements include 100% of a controlled subsidiary’s earnings, rather than only our share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control. Our business is dependent on external weather factors. Historically, we have experienced strong sales and net income in our first, second and fourth fiscal quarters comprising the three-month periods ending August 31, November 30, and May 31, respectively, with weaker performance in our third fiscal quarter (December through February).
New Pronouncements Adopted and Issued	NEW ACCOUNTING PRONOUNCEMENTS New Pronouncements Adopted In September 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2022-04, "Liabilities - Supplier Finance Programs (Subtopic 405-50)," which is intended to establish disclosures that enhance the transparency of a supplier finance program used by an entity in connection with the purchase of goods and services. This guidance requires annual and interim disclosure of the key terms of outstanding supplier finance programs, the amount outstanding under such programs including where they are recorded on the balance sheet, and a roll-forward of the related obligations. The new standard does not affect the recognition, measurement, or financial statement presentation of the supplier finance program obligations. These amendments are effective for fiscal years beginning after December 15, 2022, except for the amendment on roll-forward information, which is effective for fiscal years beginning after December 15, 2023. We adopted the new standard on June 1, 2023, on a retrospective basis other than the roll-forward guidance, which we plan to adopt on a prospective basis beginning with our fiscal 2025 annual financial statements. As of adoption on June 1, 2023, we did not have any material supplier finance program obligations; however, we began such an arrangement during the fourth quarter of fiscal 2024. Refer to Note 14, “Supply Chain Financing,” to the Consolidated Financial Statements. New Pronouncements Issued In November 2024, the FASB issued ASU 2024-03, " Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)." Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03. The standard provides guidance to expand disclosures related to the disaggregation of income statement expenses. The standard requires, in the notes to the financial statements, disclosure of specified information about certain costs and expenses which includes purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption. This guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, on a retrospective or prospective basis, with early adoption permitted. We are currently evaluating this ASU to determine its impact on our disclosures. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. The guidance makes several other changes to income tax disclosure requirements. This guidance is effective for fiscal years beginning after December 15, 2024, on a retrospective or prospective basis. Early adoption is permitted. We are currently evaluating this ASU to determine its impact on our disclosures. In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which expands disclosures about a public business entity's reportable segments and provides for more detailed information about a reportable segment's expenses. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. Early adoption is permitted. We are currently evaluating this ASU to determine its impact on our disclosures.
