Organization, Consolidation and Presentation of Financial Statements [Abstract]
Significant Accounting Policies	NOTE A – SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with United States ("U.S.") generally accepted accounting principles for interim financial reporting ("U.S. GAAP") and U.S. Securities and Exchange Commission ("SEC") regulations. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. These Condensed Consolidated Financial Statements omit certain information and footnote disclosures required for complete annual financial statements and, therefore, should be read in conjunction with the Ashland Inc. and consolidated subsidiaries ("Ashland" or the "Company") Annual Report on Form 10-K for the fiscal year ended September 30, 2024, filed with the SEC on November 18, 2024. Results of operations for the period ended March 31, 2025, are not necessarily indicative of the expected results for the remainder of the fiscal year. Ashland is comprised of the following reportable segments: Life Sciences, Personal Care, Specialty Additives and Intermediates. Unallocated and Other includes corporate governance activities and certain legacy matters. For additional information about Ashland's reportable segments, see Note Q of the Notes to the Condensed Consolidated Financial Statements. Use of estimates, risks and uncertainties The preparation of Ashland’s Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosures of contingent assets and liabilities. Significant items that are subject to such estimates and assumptions include, but are not limited to, environmental remediation, asbestos litigation, accounting for goodwill and other indefinite-lived intangible assets and income taxes. Although management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ significantly from the estimates under different assumptions or conditions. Ashland’s results are affected by domestic and international economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, government fiscal policies and changes in the prices of certain key raw materials, can have a significant effect on operations. While Ashland maintains reserves for anticipated liabilities and carries various levels of insurance, Ashland could be affected by civil, criminal, regulatory or administrative actions, claims or proceedings relating to asbestos, environmental remediation, income taxes or other matters. New accounting pronouncements A description of new U.S. GAAP accounting standards issued or adopted during the current year is required in interim financial reporting. A detailed listing of new accounting standards relevant to Ashland is included in the Annual Report on Form 10-K for the fiscal year ended September 30, 2024. Since that date, in November 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures” (“ASU 2024-03”) to expand expense disclosures by requiring disaggregated disclosure of certain income statement expense line items, including those that contain purchases of inventory, employee compensation, depreciation and amortization. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, or Ashland's fiscal 2028, and subsequent interim periods, with early adoption permitted. The amendments should be applied prospectively, but retrospective application is permitted. The Company is currently assessing the impact of the requirements on our Condensed Consolidated Financial Statements. No other new accounting pronouncements recently adopted or issued had or are expected to have a material impact on the Condensed Consolidated Financial Statements.
