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," "Keysight" or the "company"), incorporated in Delaware on December 6, 2013, is a global innovator in the computing, communications and electronics market, committed to advancing our customers’ business success by helping them solve critical challenges in the development and commercialization of their products and services. Our mission, "accelerating innovation to connect and secure the world," speaks to the value we provide our customers in a world of ever-increasing technological complexity. We deliver this value through a broad range of design and test solutions that address the critical challenges our customers face in bringing their innovations to market faster. 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 January 31, 2024 and October 31, 2023, results of operations for the three months ended January 31, 2024 and 2023, and cash flows for the three months ended January 31, 2024 and 2023. Principles of consolidation. The consolidated financial statements include the accounts of the company and our wholly- and majority-owned subsidiaries. All significant inter-company transactions have been eliminated. The consolidated financial statements also reflect the impact of non-controlling interests. Non-controlling interests do not have a significant impact on our consolidated results of operations; therefore, net income attributable to non-controlling interests of $4 million is not presented separately and is included in "other income (expense), net" in our condensed consolidated statements of operations. 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. Acquisition of ESI Group SA. In the first quarter of fiscal 2024, we acquired all of the outstanding common stock of ESI Group SA ("ESI Group") for $935 million, net of cash acquired, using existing cash. See Note 2, Acquisitions, for further information of the acquisition of ESI Group. Update to Significant Accounting Policies. There have been no material changes to our significant accounting policies as described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2023. New Accounting Pronouncements. 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.
