Accounting Policies [Abstract]
Use of Estimates	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	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	Fiscal Year and Fiscal Quarter End. Historically, our fiscal year had been 52- or 53-week periods ending on the Saturday nearest to October 31. Fiscal 2024 was a 53-week year ending on November 2, 2024. We have changed our fiscal year end from the Saturday nearest to October 31 and consisting of 52 or 53 fiscal weeks to a fiscal year end of October 31 each year. The fiscal year change became effective with our fiscal 2025, which began on November 3, 2024. Our fiscal quarters will end on January 31, April 30, July 31 and October 31 of each year. The second quarter of fiscal 2025 and 2024 ended on April 30, 2025 and May 4, 2024, respectively. Our results of operations for the first six months of fiscal 2025 and fiscal 2024 included 179 days and 189 days, respectively. For presentation purposes, the condensed consolidated financial statements and accompanying notes refer to the closest calendar month end.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which applies to all equity securities measured at fair value that are subject to contractual sale restrictions. This change prohibits entities from taking into account contractual restrictions on the sale of equity securities when estimating fair value and introduces required disclosures for such transactions. We adopted the standard as of the beginning of fiscal 2025 on a prospective basis and the adoption did not have a material impact on our condensed consolidated financial statements. Recently Issued Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The ASU expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the Chief Operating Decision Maker (CODM) and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. The ASU is effective for our annual reports beginning in fiscal 2025, and interim period reports beginning in fiscal 2026. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and related disclosures. We will adopt this ASU for our annual report for the fiscal year ending October 31, 2025. 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 will be effective for us beginning in fiscal 2026 and will be applied on a prospective basis. Early adoption is 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.
Restricted cash	Restricted cash. We include amounts generally described as restricted cash in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown in the condensed consolidated statements of cash flows. Restricted cash is primarily associated with office leases and employee loan programs.
Fair Value Measurements	ASC 820-10, Fair Value Measurements and Disclosures, defines fair value, establishes guidelines and enhances disclosure requirements for fair value measurements. The accounting guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The accounting guidance also establishes a fair value hierarchy based on the independence of the source and objective evidence of the inputs used. There are three fair value hierarchies based upon the level of inputs that are significant to fair value measurement: Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical instruments in active markets; Level 2—Observable inputs other than quoted prices for identical instruments in active markets, quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in inactive markets, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets; and Level 3—Unobservable inputs derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable. On a recurring basis, we measure the fair value of certain assets and liabilities, which include cash equivalents, short-term investments, non-qualified deferred compensation plan assets, contingent consideration receivable, and foreign currency derivative contracts. Our cash equivalents and short-term investments are classified within Level 1 or Level 2 because they are valued using quoted market prices in an active market or alternative independent pricing sources and models utilizing market observable inputs. Our non-qualified deferred compensation plan assets consist of money market and mutual funds invested in domestic and international marketable securities that are directly observable in active markets and are therefore classified within Level 1. Our foreign currency derivative contracts are classified within Level 2 because these contracts are not actively traded, and the valuation inputs are based on quoted prices and market observable data of similar instruments. Our borrowings under our Credit and Term Loan facilities are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon market rates currently available to us for debt with similar terms and maturities. See Note 10. Senior Notes, Bridge Commitment Letter, Term Loan and Revolving Credit Facilities of the Notes to Condensed Consolidated Financial Statements for more information on these borrowings. Our contingent consideration receivable, which was recorded in connection with the Software Integrity Divestiture, was classified within Level 3 because it was estimated using significant inputs that were not observable in the market. See Note 3. Discontinued Operations of the Notes to Condensed Consolidated Financial Statements for additional information.
