Accounting Policies [Abstract]
OVERVIEW, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Overview. Keysight Technologies, Inc. (“we,” “us,” “our,” “Keysight” or “the company”), incorporated in Delaware on December 6, 2013, serves technology innovators as a mission-critical design enablement partner for the world’s most complex engineering challenges. By connecting market-leading design, emulation, and test solutions across the full lifecycle, Keysight helps engineering teams accelerate innovation, reduce risk, and bring new technologies to market on ever-shorter schedules. Customers across artificial intelligence infrastructure, communications, industrial automation, aerospace and defense, automotive, semiconductor, and general electronics rely on Keysight to bridge virtual design and physical reality, enabling confident decisions earlier. Our fiscal year-end is October 31, and our fiscal quarters end on January 31, April 30, and July 31. Unless otherwise stated, these dates refer to our fiscal year and fiscal quarters. Basis of Presentation. We have prepared the accompanying financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The accompanying financial statements and information should be read in conjunction with our Annual Report on Form 10-K. In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary to state fairly our financial position as of July 31, 2026 and October 31, 2025, results of operations for the three and nine months ended July 31, 2026 and 2025, and cash flows for the nine months ended July 31, 2026 and 2025. Principles of Consolidation. The condensed consolidated financial statements include the accounts of the company and our wholly- and majority-owned subsidiaries. All significant inter-company transactions have been eliminated. Use of Estimates. The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. IEEPA Tariff Refund Claims and Related Customer Surcharge Refunds. In February 2026, the Supreme Court of the United States (“U.S. Supreme Court”) determined that certain tariffs imposed pursuant to the International Emergency Economic Powers Act (“IEEPA”) were not authorized by law. Subsequent rulings by the U.S. Court of International Trade have directed the U.S. Customs and Border Protection to establish processes to effect refunds of certain tariffs previously collected. Based on these judicial determinations, we concluded that the company has been legally released from the obligation underlying the invalidated tariffs in accordance with the legal release model within the scope of Accounting Standards Codification 405, Liabilities, and that we have a present right to repayment of amounts previously paid. Accordingly, during the nine months ended July 31, 2026, we recorded a receivable of $100 million within “other current assets” in the condensed consolidated balance sheet, representing recovery of IEEPA tariffs previously paid and accrued statutory interest, with corresponding offsets of $93 million to “cost of sales,” $4 million to “selling, general and administrative expenses,” and $3 million to “interest income” in the condensed consolidated statement of operations. In addition, we recorded a $40 million liability within “other accrued liabilities” in the condensed consolidated balance sheet as a result of our decision to refund IEEPA tariff surcharges collected from our customers, with a corresponding reduction of revenue in the condensed consolidated statement of operations. In the three and nine months ended July 31, 2026, we received $37 million in IEEPA tariff refund proceeds, resulting in outstanding IEEPA tariff refund claims receivable of $64 million within “other current assets” in the condensed consolidated balance sheet, representing recovery of IEEPA tariffs previously paid. For discussion of risks related to tariff refund claims, see Part II, Item 1A, Risk Factors. Update to Significant Accounting Policies. There have been no additional material changes to our significant accounting policies as described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2025. New Accounting Pronouncements Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. In December 2023, the Financial Accounting Standards Board (“FASB”) issued guidance that requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and provides additional information for reconciling items that meet a quantitative threshold. This standard is effective for fiscal years beginning after December 15, 2024. We will adopt the standard on the effective date in our annual reporting for fiscal year 2026. ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. In November 2024, the FASB issued guidance that requires disclosure of additional expense information on an annual and interim basis, including inventory purchases, employee compensation, depreciation, and intangible asset amortization included within each income statement expense caption. This standard is effective for fiscal years beginning after December 15, 2026. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and disclosures. Other amendments to GAAP that do not require adoption until a future date are not expected to have a material impact on our condensed consolidated financial statements upon adoption.
