Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Basis of Presentation	Summary of Significant Accounting Policies and Basis of Presentation We have prepared the accompanying condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Pursuant to these rules and regulations, we have condensed or omitted certain information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The condensed consolidated financial statements are unaudited but, in management’s opinion, we have made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary for a fair presentation of our quarterly results. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended October 31, 2025 as filed with the SEC on December 22, 2025 (our Annual Report). Use of Estimates. To prepare financial statements in conformity with U.S. GAAP, management must make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and could have a material impact on our operating results and financial position. Principles of Consolidation. The condensed consolidated financial statements include our accounts and the accounts of our wholly and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Fiscal Year and Fiscal Quarter End. Our fiscal year end is October 31 and our fiscal quarters end on January 31, April 30, and July 31 of each year. Acquisition of Ansys. On July 17, 2025 (the Acquisition Date), we completed the acquisition of ANSYS, Inc. (Ansys), a provider of broad engineering simulation and analysis software and services for $199.91 in cash and 0.3399 of a share of our common stock in exchange for each ordinary share of Ansys for a total consideration of $34.9 billion. We accounted for the acquisition of Ansys by applying the acquisition method of accounting for business combinations. See Note 4. Business Combination and Note 10. Senior Notes, Bridge Commitment Letter, Term Loan and Revolving Credit Facilities of the Notes to Consolidated Financial Statements in our Annual Report for additional information. Significant Accounting Policies. There have been no material changes to our significant accounting policies included in our Annual Report. Recent Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures primarily through changes to the rate reconciliation and income taxes paid information. The ASU is effective for our annual reports beginning in fiscal 2026 with early adoption permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income-Expense Disaggregation (Subtopic 220-40): Disaggregation of Income Statement Expenses. The ASU requires the disclosure of additional information related to certain costs and expenses, including amounts of inventory purchases, employee compensation, and depreciation and amortization included in each income statement line item. The ASU also requires disclosure of the total amount of selling expenses and our definition of selling expenses. The ASU will be effective for our annual reports beginning in fiscal 2028, and interim period reports beginning in fiscal 2029 either on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures. In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The ASU allows companies to apply a practical expedient when estimating credit losses on current accounts receivable and contract assets. The ASU will be effective for us beginning in fiscal 2027 and will be applied on a prospective basis. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures.
