Accounting Policies [Abstract]
OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. OVERVIEW, BASIS OF PRESENTATION 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 technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world by providing electronic design and test solutions that are used in the simulation, design, validation, manufacture, installation, optimization and secure operation of electronics systems in the communications, networking and electronics industries. We also offer customization, consulting and optimization services throughout the customer's product development lifecycle, including start-up assistance, asset management, up-time services, application services and instrument calibration and repair. Basis of Presentation. We have prepared the accompanying financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and in conformity with generally accepted accounting principles in the U.S. ("GAAP"). Our fiscal year end is October 31. Unless otherwise stated, all years and dates refer to our fiscal year. Management is responsible for the fair presentation of the accompanying consolidated financial statements, prepared in accordance with GAAP, and has full responsibility for their integrity and accuracy. In the opinion of management, the accompanying consolidated financial statements contain all normal and recurring adjustments necessary to present fairly our consolidated balance sheet and our consolidated statement of operations, statement of comprehensive income, statement of cash flows and statement of equity. 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. Use of Estimates. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in our 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. We are not aware of any specific event or circumstance that would require an update to our estimates or judgments or a revision of the carrying value of our assets or liabilities as of October 31, 2022. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are revenue recognition, inventory valuation, share-based compensation, retirement and post-retirement plan assumptions, valuation of goodwill and other intangible assets, warranty, loss contingencies, restructuring and accounting for income taxes. Revenue recognition. Revenue is recognized upon transfer of control of the promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We primarily generate revenue from the sale of products (hardware and/or software), services, or a combination thereof. We enter into contracts that may involve multiple performance obligations, and we allocate the transaction price between each performance obligation on the basis of relative standalone selling price ("SSP"). Revenue is recognized net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities. Product revenues are generated predominantly from the sale of various types of design and test software and hardware. Products consist of standalone software and hardware generally installed with software applications that are licensed on a perpetual and term basis. Our hardware products generally do not have any substantive acceptance terms that would otherwise preclude the transfer of control. Performance obligations related to our software licenses, including the license portion of our software subscriptions, grant the customer the right to use our software primarily via electronic delivery. Service revenues consist of repair and calibration services, extended warranties, technical support for hardware and software, when-and-if available software updates and upgrades, and professional services, including installation and implementation, consulting, and training. Services include both hardware and software services. Repair and calibration services for hardware products are sold both as per-incident customer services and as customer agreements to provide such services over the contractual period. Extended warranties are optional to the customer and provide warranty on hardware products for additional years beyond the standard one-year warranty. Technical support for software and when-and-if available software updates and upgrades are sold either together with our software licenses and software subscriptions, or separately as part of our customer support programs. These are considered stand-ready performance obligations where customers benefit from the services evenly throughout the license or service period. These performance obligations provide the customer access evenly over the contract period. Our professional services may be sold on a time and material basis (e.g., consulting) or on a fixed-fee basis (e.g., non-recurring engineering). We also generate revenues from a combination of products and services ("custom solutions"), including combinations of hardware, software, software subscriptions, installation, professional services, and other support services. Custom solutions provide the customer with a combination of hardware, software and professional services to meet customers' unique specifications and are accounted for as one performance obligation. For our contracts with customers, we account for individual performance obligations separately if they are distinct. Our standard payment terms are net 30 to 90 days, and we generally do not offer extended payment terms beyond one year. Our contracts typically contain various forms of variable consideration, including trade discounts, trade-in credits, rebates, and rights of return. The transaction price is allocated to the separate performance obligations based on relative SSP. SSPs for a majority of our products and services are estimated based on our established pricing practices and maximize the use of observable inputs. An observable input is the price of the good or service when it is sold as a separate item in a similar circumstance and to a similar customer as in the contract for which SSPs are being determined. We have elected to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by Keysight from a customer (e.g., sales, use, value added, and some excise taxes). We have also elected to account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of assessing such activities as performance obligations. Our typical performance obligations include the following: Performance obligation When performance obligation is typically satisfied When payment is typically due How standalone selling price is typically determined Product Revenues Hardware When customer obtains control of the product, typically at delivery (point in time) Within 30-90 days of shipment Estimated based on established pricing practices or observable based on standalone sales for certain hardware products Software licenses Primarily upon electronic delivery of the software, and the applicable license period has begun (point in time) Within 30-90 days of the beginning of license period Estimated based on established pricing practices or observable based on standalone sales for certain software products Software subscriptions Ratably over the subscription period (over time) Within 30-90 days of the beginning of subscription period Estimated based on established pricing practices Service Revenues Calibration contracts Ratably over the service contract period (over time) Within 30-90 days of the beginning of service contract period Estimated based on established pricing practices Repair and calibration (per- incident) As services are performed (point in time) Within 30-90 days of invoicing for services rendered Estimated based on established pricing practices Extended hardware warranty Ratably over the warranty period (over time) Within 30-90 days of invoicing Estimated based on established pricing practices or observable based on standalone sales of certain hardware warranty contracts Technical support and when-and-if-available software updates Ratably over the license service contract period (over time) Within 30-90 days of the beginning of license or service contract period Estimated based on established pricing practices or observable based on standalone sales for certain support contracts Professional services As services are performed based on measures of progress (over time) or at a point in time Within 30-90 days of invoicing for services rendered Estimated based on established pricing practices Custom Solutions Custom solutions (milestone-based; percentage-of-completion) As milestones are achieved based on transfer of control to customer (over time) Within 30-90 days of milestone achievement Transaction price, as pricing is custom and can vary significantly from contract to contract Custom solutions (point in time) When customer obtains control of the solution, typically at delivery or customer acceptance, as defined by the contract (point in time) Within 30-90 days of delivery of solution Transaction price, as pricing is custom and can vary significantly from contract to contract Significant judgment is required to determine the SSP for each distinct performance obligation. As most of our products and services are not sold on a standalone basis, we typically estimate the SSP. In doing so, we consider our internal price list for each product and service, which reflects our desired profitability, based on an expected level of sales, and adjust for factors such as competition, customer relationship, discount provided in the contract, geographic location, and the products and services purchased in the arrangement. We use a range based on actual historical sales to determine whether the calculated SSP for a product or service is a fair representation of the SSP. For capitalized contract costs, we use judgment in determining the capitalized amount and amortization period. Our products are generally sold with a right of return and we may provide other credits, discounts, or incentives, which are accounted for as variable consideration at the portfolio level and estimated based on historical information. Returns, credits, and discounts are estimated at contract inception and updated at the end of each reporting period as additional information becomes available to the extent that it is probable a significant reversal of the cumulative amount of revenue recognized will not occur once the variability is subsequently resolved. Shipping and handling costs. Our shipping and handling costs charged to customers are included in revenue, and the associated expense is recorded in cost of products for all periods presented. Deferred revenue. We recognize contract liabilities in our consolidated balance sheet as deferred revenue, which represents the amount of service and software revenue deferred and recognized over the contractual period or as services are rendered and accepted by the customer. In addition, it includes the amount allocated to undelivered performance obligations. Accounts receivable, net. Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Such accounts receivable have been reduced by an allowance for credit losses, which is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on customer specific experience and the aging of such receivables, among other factors. The allowance for credit losses was approximately $4 million as of both October 31, 2022 and 2021. We do not have any off-balance-sheet credit exposure related to our customers. Share-based compensation. We account for share-based awards made to our employees and directors, including restricted stock units ("RSUs"), employee stock purchases made under Keysight's employee stock purchase plan under Section 423(b) of the Internal Revenue Code ("ESPP"), employee stock option awards, and performance share awards under Keysight Technologies, Inc. Long-Term Performance ("the LTP") Program, using the estimated grant date fair value method of accounting. We recorded compensation expense for all share-based awards of $126 million in 2022, $104 million in 2021 and $93 million in 2020. Inventory. Inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of market value. We assess the valuation of our inventory on a periodic basis and make adjustments to the value for estimated excess and obsolete inventory based on estimates about future demand and actual usage. The excess balance determined by this analysis becomes the basis for our excess inventory charge. Our excess inventory review process includes analysis of sales unit forecasts, managing product rollovers and working with manufacturing to maximize recovery of excess inventory. Warranty. Keysight warranties on products sold through direct sales channels are primarily for one year. Warranties for products sold through distribution channels are primarily for three years. We accrue for standard warranty costs based on historical trends in warranty charges. The accrual is reviewed regularly and periodically adjusted to reflect changes in warranty cost estimates. Estimated warranty charges are recorded within cost of products at the time related product revenue is recognized. See Note 13, "Supplemental financial information". We also sell extended warranties that provide warranty coverage beyond the standard warranty term. Revenue associated with extended warranties is deferred and recognized over the extended coverage period. Loss contingencies. We accrue for probable losses from contingencies, including legal settlement costs, on an undiscounted basis when such costs are considered probable of being incurred and are reasonably estimable. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary. Taxes on income. Income tax expense is based on income or loss before taxes. Deferred income taxes reflect the effect of temporary differences between asset and liability amounts that are recognized for financial reporting purposes and the amounts that are recognized for income tax purposes. These deferred taxes are measured by applying currently enacted tax laws. Valuation allowances are recognized to reduce deferred tax assets to the amount that is more likely than not to be realized. We account for uncertainty in income taxes using a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50 percent likely of being realized upon settlement. We make adjustments to these reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate due to new information. We classify the liability for unrecognized tax benefits as current to the extent that the company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, we are unable to estimate the range of possible changes to the balance of our unrecognized tax benefits. Goodwill and other intangible assets. Goodwill is assessed for impairment on a reporting unit basis at least annually in the fourth quarter, as of September 30, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. The impairment test compares the fair value of a reporting unit with its carrying amount, with an impairment charge recorded for the amount by which the carrying amount exceeds the reporting unit’s fair value up to a maximum amount of the goodwill balance for the reporting unit. We determine fair values for each of the reporting units using the market approach, when available and appropriate, or the income approach, or a combination of both. If multiple valuation methodologies are used, the results are weighted appropriately. Valuations using the market approach are derived from metrics of publicly traded comparable companies. The selections of comparable businesses are based on the markets in which our reporting units operate, giving consideration to risk profiles, size, geography and diversity of products and services. Under the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. We use our internal forecasts to estimate future cash flows and include an estimate of long-term future growth rates based on our most recent views of the long-term outlook for each business. As defined in the authoritative guidance, a reporting unit is an operating segment or one level below an operating segment. During the fourth quarter of 2022, we performed our annual impairment test of goodwill for all our reporting units using a qualitative approach. Based on the results of our qualitative testing, we believe that it is more-likely-than-not that the fair value of each reporting unit is greater than its respective carrying value. There were no impairments of goodwill during the years ended October 31, 2022, 2021 and 2020. See Note 2, “Acquisitions,” and Note 7, “Goodwill and Other Intangible Assets,” for additional information about our goodwill and other intangible assets. Other intangible assets consist primarily of developed technologies, proprietary know-how, trademarks, customer relationships, non-compete agreements, and acquired backlog and are amortized using the straight-line method over estimated useful lives ranging from 6 months to 12 years. We review other intangible assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. No impairments of purchased intangible assets were recorded during the years ended October 31, 2022, 2021 and 2020. The authoritative accounting guidance allows a qualitative approach for testing indefinite-lived intangible assets for impairment, similar to the impairment testing guidance for goodwill. It allows the option to first assess qualitative factors (events and circumstances) that could have affected the significant inputs used in determining the fair value of the indefinite-lived intangible asset. The qualitative factors assist in determining whether it is more-likely-than-not that the indefinite-lived intangible asset is impaired. An organization may choose to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to calculating its fair value. Our indefinite-lived intangible assets are in-process research and development ("IPR&D") intangible assets. In 2022, 2021 and 2020 we assessed impairment by performing a qualitative test and concluded that no material impairment of indefinite-lived intangible assets was required. Advertising. Advertising costs are expensed as incurred and were $27 million in 2022, $21 million in 2021 and $24 million in 2020. Research and development. Costs related to the research, design and development of our products are charged to research and development expense as they are incurred. Investments. Investments with readily determinable fair values and trading securities are reported at fair value. Equity investments without readily determinable fair values are measured at cost with adjustments for observable changes in price or impairments. Gains or losses resulting from changes in fair value are recognized currently in earnings. The company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may not be recoverable. There was no impairment recognized in 2022, 2021 and 2020. Net income per share. Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period excluding the dilutive effect of stock options and other employee stock plans. Diluted net income per share gives effect to all potentially dilutive common stock equivalents outstanding during the period. The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense, and the dilutive effect of in-the-money options and non-vested RSUs. Under the treasury stock method, the amount the employee must pay for exercising stock options and unamortized share-based compensation expense are assumed proceeds to be used to repurchase hypothetical shares. Cash, cash equivalents and short-term investments. We classify investments as cash equivalents if their original maturity or remaining maturity at the time of purchase is three months or less at the date of purchase. Cash equivalents are stated at cost, which approximates fair value. As of October 31, 2022, approximately $1.7 billion of our cash, cash equivalents and restricted cash was held outside of the U.S. in our foreign subsidiaries. Our cash and cash equivalents mainly consist of investments in institutional money market funds, short-term deposits held at major global financial institutions, and similar short duration instruments with original maturities of three months or less. We continuously monitor the creditworthiness of the financial institutions in which we invest our funds. We utilize a variety of funding strategies in an effort to ensure that our worldwide cash is available in the locations in which it is needed. Most significant international locations have access to internal funding through an offshore cash pool for working capital needs. In addition, a few locations that are unable to access internal funding have access to temporary local overdraft and short-term working capital lines of credit. We classify investments as short-term investments if their original maturities are greater than three months and their remaining maturities are one year or less. Fair value of financial instruments. The carrying values of certain of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities, approximate fair value because of their short maturities. The fair value of long-term equity investments is determined using quoted market prices for those securities when available. For those long-term equity investments accounted for under the equity method or measurement alternative, the carrying value approximates estimated fair value. The fair value of our long-term debt, calculated from quoted prices that are primarily Level 1 inputs under the accounting guidance fair value hierarchy, is approximately $1,679 million and $1,977 million as of October 31, 2022 and 2021, respectively. The fair value of foreign currency contracts used for hedging purposes is estimated internally by using inputs tied to active markets. These inputs, for example, interest rate yield curves, foreign exchange rates, and forward and spot prices for currencies, are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. See also Note 8, "Fair Value Measurements," for additional information on the fair value of financial instruments. Concentration of credit risk. Financial instruments that potentially subject us to significant concentration of credit risk include money market fund investments, time deposits and demand deposit balances. These investments are categorized as cash and cash equivalents, short-term investments and long-term investments. In addition, we have credit risk from derivative financial instruments used in hedging activities and accounts receivable. We invest in a variety of financial instruments and limit the amount of credit exposure with any one financial institution. We have a comprehensive credit policy in place and credit exposure is monitored on an ongoing basis. Credit risk with respect to our accounts receivable is diversified due to the large number of entities comprising our customer base and their dispersion across many different industries and geographies. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated through collateral, such as letters of credit, bank guarantees or payment terms like cash in advance. N o single customer accounted for more than 10 percent of accounts receivabl e as of October 31, 2022 or 2021. Derivative instruments. We are exposed to global foreign currency exchange rate fluctuations in the normal course of business. We enter into foreign exchange hedging contracts, and primarily use forward contracts to manage financial exposures resulting from changes in foreign currency exchange rates. Foreign currency exposures include committed and anticipated revenue and expense transactions (cash flow exposure) and assets and liabilities that are denominated in currencies other than the functional currency of the subsidiary (balance sheet exposure). For cash flow hedges, contracts are designed at inception as hedges of the related foreign currency exposures. We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions at the inception of the hedge. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the hedging instruments are highly effective in offsetting changes in cash flows of hedged items. Our foreign exchange cash flow hedging contracts have maturities based on a rolling period of up to twelve months. We do not use derivative financial instruments for speculative trading purposes. All derivatives are recognized on the balance sheet at their fair values. For derivative instruments that are designated and qualify as a cash flow hedge, changes in the value of the effective portion of the derivative instrument is recognized in accumulated comprehensive income, a component of stockholders' equity. Amounts associated with cash flow hedges are reclassified and recognized in income when either the forecast transaction occurs or it becomes probable the forecast transaction will not occur. Derivatives not designated as hedging instruments are recorded on the balance sheet at fair value, and changes in fair value are recorded in earnings in the current period. Derivative instruments are subject to master netting arrangements and qualify for net presentation in the balance sheet. Cash flows from derivative instruments are classified in the statement of cash flows in the same category as the cash flows from the hedged or economically hedged item, primarily in operating activities. Property, plant and equipment. Property, plant and equipment are stated at cost less accumulated depreciation. Additions, improvements and major renewals are capitalized; maintenance, repairs and minor renewals are expensed as incurred. When assets are retired or disposed of, the assets and related accumulated depreciation are removed from our general ledger, and the resulting gain or loss is reflected in the consolidated statement of operations. We use the straight-line method to depreciate assets. Buildings and improvements are depreciated over the lesser of their useful lives, which is generally over five years to forty years, or the remaining term of the lease; and machinery and equipment is generally depreciated over three years to ten years. Leases . We adopted Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC 842”), on November 1, 2019 using the modified retrospective transition approach provided by Accounting Standards Update ("ASU") 2018-11, Leases: Targeted Improvements, with the cumulative effect of initially applying the standard recognized at the date of adoption. We determine whether an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities (current and non-current) on our consolidated balance sheet. Finance leases are included in property, plant and equipment, other accrued liabilities, and other long-term liabilities in our consolidated balance sheet. Our finance lease and lessor arrangements are immaterial. ROU assets and lease obligations are recognized based on their present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the lease term and economic environment to discount lease obligations. ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. We initially measure payments based on an index by using the applicable rate at lease commencement. Variable payments that do not depend on an index are not included in the lease liability and are recognized as they are incurred. See Note 10, "Leases," for additional information. Impairment of long-lived assets. We continually monitor events and changes in circumstances that could indicate carrying amounts of long-lived assets may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the undiscounted future cash flows is less than the carrying amount of those assets, we recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets. Restructuring costs. The main component of our existing restructuring plans is related to workforce reductions and site restructuring. Workforce reduction charges are accrued when payment of benefits becomes probable and the amounts can be estimated. If the amounts and timing of cash flows from restructuring activities are significantly different from what we have estimated, the actual amount of restructuring and other related charges could be materially different, either higher or lower, than those we have recorded. Employee compensation and benefits. Amounts owed to employees, such as accrued salary, bonuses and vacation benefits are reported within employee compensation and benefits in the consolidated balance sheet. The total amount of accrued vacation benefit was $109 million and $114 million as of October 31, 2022 and 2021, respectively. Foreign currency translation. We translate and remeasure balance sheet and statement of operations items into U.S. dollars. For those subsidiaries that operate in a local currency functional environment, all assets and liabilities are translated into U.S. dollars using current exchange rates at the balance sheet date; revenue and expenses are translated using monthly exchange rates that approximate average exchange rates in effect during each period. Resulting translation adjustments are reported as a sepa

ACQUISITIONS	2. ACQUISITIONS 2022 Acquisitions During the year ended October 31, 2022, we used $33 million, net of cash acquired, for acquisition activity and recognized goodwill and other intangible assets of $20 million and $23 million, respectively, based on the allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed. Of the $20 million goodwill, $9 million was assigned to the Communications Solutions Group and $11 million was assigned to the Electronic Industrial Solutions Group. 2021 Acquisitions Acquisition of Sanjole During the first quarter of fiscal 2021, we acquired Sanjole Inc. ("Sanjole") for $102 million, net of $11 million cash acquired, and recognized additions to goodwill and other intangible assets of $48 million and $51 million, respectively, based on the allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed. We expect the goodwill recognized on the Sanjole acquisition or any potential impairment charges in the future to be deductible for income tax purposes. The identified intangible assets primarily consist of developed technology of $24 million, customer relationships of $17 million and in-process R&D of $7 million. The estimated useful lives of developed technology and customer relationships are 7 years and 9 years, respectively. Sanjole is a leader in wireless test and measurement solutions for protocol decoding and interoperability. Additionally, we acquired two other businesses for $76 million, net of cash acquired, and recognized goodwill and other intangible assets of $52 million and $32 million, respectively, based on the preliminary allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed. Goodwill for the acquisitions was assigned to the Communications Solutions Group. Supplemental Pro Forma Information (Unaudited) Pro forma results of operations for 2022 and 2021 acquisitions have not been presented because the effects of the acquisitions were not material to the company’s financial results.

Perpetual software and the portion of term software subscription revenue in this category represents revenue recognized up front upon transfer of control at the time of electronic delivery. Revenue on per-incident repair and calibration services is recognized when services are performed. Over-time revenues are generated predominantly from the repair and calibration contracts, extended warranties, technical support for hardware and software, certain software subscription and Software as a Service ("SaaS") product offerings, and professional services. Technical support for software and when-and-if available software updates and upgrades are sold either together with our software licenses and software subscriptions, including SaaS, or separately as part of our customer support programs. Additionally, we provide custom solutions that include combinations of hardware, software, software subscriptions, installation, professional services, and other support services, and revenue may be recognized either up front on delivery or over time depending upon the terms of the contract. Contract Balances Contract assets Contract assets consist of unbilled receivables and are recorded when revenue is recognized in advance of scheduled billings to our customers. These amounts are primarily related to solutions and support arrangements when transfer of control has occurred but we have not yet invoiced. The contract assets balances were $88 million and $84 million as of October 31, 2022 and October 31, 2021, respectively, and are included in "accounts receivables, net" and "other assets" in our consolidated balance sheet. Contract costs We capitalize direct and incremental costs incurred to acquire contracts for which the associated revenue is expected to be recognized in future periods. We have determined that certain employee and third-party representative commission programs meet the requirements to be capitalized. These costs are initially deferred and typically amortized over the term of the customer contract which corresponds to the period of benefit. Capitalized contract costs were $38 million and $39 million as of October 31, 2022 and October 31, 2021, respectively, and are included in “other current assets” and “other assets” in the consolidated balance sheet. The amortization expense associated with these costs was $84 million, $77 million and $83 million for the years ended October 31, 2022, 2021 and 2020, respectively. Contract liabilities Our contract liabilities consist of deferred revenue that arises when we receive consideration in advance of providing the goods or services promised in the contract. Contract liabilities are primarily generated from customer deposits received in advance of shipments for products or rendering of services and are recognized as revenue when services are provided to the customer. We classify deferred revenue as current or non-current based on the timing of when we expect to recognize revenue. Balance at October 31, 2021 $ 665 Deferral of revenue billed in current period, net of recognition 546 Revenue recognized that was deferred as of the beginning of the period (482) Foreign currency translation impact (37) Balance at October 31, 2022 $ 692 Remaining Performance Obligations Our expected remaining performance obligations, excluding contracts that have an original expected duration of one year or less, was approximately $433 million as of October 31, 2022, and represents the company’s obligation to deliver products and services and obtain customer acceptance on delivered products. As of October 31, 2022, we expect to recognize approximately 47 percent of the revenue related to these unsatisfied performance obligations during 2023, 33 percent in 2024 and 20 percent thereafter.

Share-Based Payment Arrangement, Noncash Expense [Abstract]
SHARE-BASED COMPENSATION	4. SHARE-BASED COMPENSATION Keysight accounts for share-based awards in accordance with the provisions of the authoritative accounting guidance, which requires the measurement and recognition of compensation expense for all share-based payment awards made to our employees and directors, including RSUs, employee stock purchases made under our employee stock purchase plan ("ESPP"), employee stock option awards, and performance share awards granted to selected members of our senior management under the LTP Program, based on estimated fair values. Description of Keysight’s Share-Based Plans Incentive compensation plans. The 2014 Equity and Incentive Compensation Plan (the "2014 Stock Plan") was originally adopted by our board of directors on July 16, 2014, subsequently amended and restated by our board of directors on September 29, 2014 and on January 22, 2015, and became effective as of November 1, 2014. Our board of directors initially reserved 25 million shares of company common stock that may be issued under the 2014 Stock Plan, plus any shares forfeited or cancelled under the 2014 Stock Plan and subsequently reduced the number to 17 million shares. The 2014 Stock Plan was further amended and restated by our board of directors on November 16, 2017 to increase the maximum aggregate number of shares that may be issued under the 2014 Stock Plan to 21.8 million shares. The 2014 Stock Plan provides for the grant of awards in the form of stock options, stock appreciation rights, restricted stock, RSUs, performance shares and performance units with performance-based conditions on vesting or exercisability, and cash awards. The 2014 Stock Plan has a term of ten years. As of October 31, 2022, approximately 5 million shares were available for future awards under the 2014 Stock Plan. Stock options granted under the 2014 Stock Plan may be either "incentive stock options," as defined in Section 422 of the Internal Revenue Code, or non-statutory. Options generally vest at a rate of 25 percent per year over a period of four years from the date of grant with a maximum contractual term of ten years. The exercise price for stock options is generally not less than 100 percent of the fair market value of our common stock on the date the stock award is granted. Performance share awards granted under the LTP Program are administered under the 2014 Stock Plan for the company's executive officers and other key employees. Participants in this program are entitled to receive unrestricted shares of the company's stock after the end of a three-year performance period, contingent upon the achievement of metrics and targets established by the Compensation and Human Capital Committee at the beginning of the performance period. The metrics for achievement of these awards can vary and may include total shareholder return ("TSR") or financial metrics, such as operating margin (“OM”), cost synergies and others. For TSR-based awards, the peer group comparisons are set at the beginning of the performance period. For OM-based awards, the performance targets are set each year in the first quarter of the respective year. The final pay-out under the LTP Program may range from zero to 200 percent of the target award based on actual performance During fiscal year 2022, the Compensation and Human Capital Committee approved performance retention awards with a target earnings per share (“EPS”) goal over a three-year performance period to select members of our leadership team. The performance targets are set each half year. The payout range of the award is zero or 100 percent, with no additional payout for performance above target. RSUs under our share-based plans are granted to directors, executives and employees. The estimated fair value of the restricted stock unit awards granted under the 2014 Stock Plan is determined based on the market price of Keysight common stock on the date of grant. RSUs generally vest, with some exceptions, at a rate of 25 percent per year over a period of four years from the date of grant. The ESPP allows eligible employees to contribute up to 10 percent of their base compensation to purchase shares of Keysight common stock at 85 percent of the closing market price at the purchase date. Shares authorized for issuance in connection with the ESPP are subject to an automatic annual increase of the lesser of one percent of the outstanding shares of Keysight common stock on November 1 or an amount determined by the Compensation and Human Capital Committee of our board of directors. Under the terms of the ESPP, in no event shall the number of shares issued under the ESPP exceed 75 million shares. Under our ESPP, employees purchased 462,279 shares for $62 million in 2022, 541,241 shares for $56 million in 2021 and 628,449 shares for $53 million in 2020. As of October 31, 2022, common stock authorized and available for issuance under our ESPP was 18,860,237 shares, which includes shares issued in November 2022 to participants in consideration of the aggregate contribution of $31 million as of October 31, 2022. Impact of Share-based Compensation Awards Share-based compensation expense has been recognized using a straight-line amortization method. The impact of share-based compensation expense on our consolidated statement of operations was as follows: Year Ended October 31, 2022 2021 2020 (in millions) Cost of products and services $ 23 $ 19 $ 16 Research and development 28 21 19 Selling, general and administrative 75 64 58 Total share-based compensation expense $ 126 $ 104 $ 93 Income tax benefit realized from exercised stock options and similar awards $ 15 $ 10 $ 12 The expense for 2022, 2021 and 2020 includes mark-to-market adjustments for financial metrics-based performance awards of $7 million, $5 million and $2 million, respectively. At October 31, 2022 and 2021, there was no share-based compensation expense capitalized within inventory. Valuation Assumptions The TSR-based performance awards were valued using a Monte Carlo simulation model, which requires the use of highly subjective and complex assumptions, including the price volatility of the underlying stock. The estimated fair value of restricted stock awards and the financial metrics-based performance awards (both OM and EPS) is determined based on the market price of Keysight’s common stock on the grant date. The compensation cost for financial metrics-based performance awards reflect the cost of awards that are probable to vest at the end of the performance period. The following assumptions were used to estimate the fair value of TSR-based performance awards. Year Ended October 31, 2022 2021 2020 Volatility of Keysight shares 36% 36% 28% Volatility of index 23% 23% 13% Price-wise correlation with selected peers 67% 67% 61% Share-based Payment Award Activity Employee Stock Options We have not granted any stock options since fiscal 2015. As of October 31, 2022 and 2021, the options outstanding were approximately 0.2 million and 0.3 million, respectively, having a weighted average exercise price of $30 and $29, respectively. During the year, 0.1 million options, with an intrinsic value of $11 million were exercised at the weighted average exercise price of $25. The intrinsic value of the options exercised during 2021 and 2020 was $14 million, respectively, at the weighted average exercise price of $26 and $27, respectively. The options outstanding as of October 31, 2022 have a weighted average contractual remaining life of 1.6 years and an intrinsic value of $27 million, based on Keysight's closing stock price of $174.15 at October 31, 2022. Non-vested Awards The following table summarizes non-vested award activity in 2022 for our LTP Program and restricted stock unit awards: Shares Weighted average grant date fair value per share (in thousands) Non-vested at October 31, 2021 2,181 $ 93 Granted 914 179 Vested (1,166) 71 Forfeited (57) 129 LTP Program incremental 220 64 Non-vested at October 31, 2022 2,092 $ 139 As of October 31, 2022, the unrecognized share-based compensation cost for non-vested stock awards was approximately $107 million, which is expected to be amortized over a weighted average period of 2.7 years. Unrecognized share-based compensation cost does not include expense for financial metrics-based performance awards for which the targets have not yet been set. The total fair value of stock awards vested was $223 million for 2022, $165 million for 2021 and $167 million for 2020. See Note 5, "Income Taxes," for the tax impact on share-based award exercises and vesting.

The decrease in deferred tax assets in 2022 as compared to 2021 primarily relates to a decrease in intangible assets in Singapore due to amortization, a decrease in U.K. net operating loss assets due to currency fluctuations, and a decrease in net pension liabilities in Germany due to remeasurement. The decrease in deferred tax liabilities in 2022 as compared to 2021 primarily relates to a decrease in Japan pension deferred tax liabilities related to currency fluctuations, a decrease in intangibles basis difference in the U.S. and U.K. due to amortization, and a decrease in taxes on unremitted earnings of foreign subsidiaries due to currency fluctuations, partially offset by an increase in deferred tax liabilities related to derivative instruments. As of October 31, 2022, there was a deferred tax liability of $8 million for the tax liability expected to be imposed upon the repatriation of unremitted foreign earnings that are not considered indefinitely reinvested. As of October 31, 2022, the cumulative amount of undistributed earnings considered indefinitely reinvested was $105 million. No deferred tax liability has been recognized on the basis difference created by such earnings since it is our intention to indefinitely reinvest those earnings in the company’s foreign operations. The amount of the unrecognized deferred tax liability on the indefinitely reinvested earnings was $4 million. Valuation allowances require an assessment of both positive and negative evidence when determining whether it is more likely than not that deferred tax assets are recoverable. Such assessment is required on a jurisdiction-by-jurisdiction basis. The $224 million and $231 million valuation allowances as of October 31, 2022 and 2021, respectively, are mainly related to net operating losses in Luxembourg and the U.K., capital losses in the U.K., and California research credits from acquired entities that are subject to change in ownership limitations. The decrease in valuation allowance is primarily due to currency fluctuations on U.K. net operating loss assets that are subject to valuation allowance. We will maintain a valuation allowance until sufficient positive evidence exists to support a reversal. At October 31, 2022, we had U.S. federal net operating loss carryforwards of approximately $6 million and U.S. state net operating loss carryforwards, primarily from acquired entities, of approximately $50 million. The U.S. federal net operating losses will expire in years beginning 2027 through 2029 if not utilized. Of the total U.S. state net operating loss carryforwards, $48 million is subject to change of ownership limitations under various state tax provisions and are subject to valuation allowance. The U.S. state net operating loss carryforwards will begin to expire in 2023, which would result in an immaterial tax impact if not utilized. At October 31, 2022, we had U.S. state research credit carryforwards of approximately $28 million. Of the total U.S. state research credit carryforwards, $25 million is California research credits that can be carried forward indefinitely. Due to change of ownership limitations, however, $21 million of California research credits is subject to valuation allowance. At October 31, 2022, we also had foreign net operating loss carryforwards of approximately $957 million. Of the total foreign loss, $5 million will expire in years beginning 2024 through 2027. The remaining loss is comprised of $673 million that will expire in years beginning 2032 through 2039 if not utilized and $279 million that has an indefinite life. Of the $957 million of foreign net operating loss carryforward, $687 million is subject to a valuation allowance. At October 31, 2022, we had foreign capital loss carryforwards of approximately $126 million with an indefinite life and $4 million of tax credits in foreign jurisdictions with an indefinite life. The foreign capital loss carryforwards are subject to valuation allowance as we do not expect to generate income of the type required in order to utilize these losses. The differences between the U.S. federal statutory income tax rate and our effective tax rate are: Year Ended October 31, 2022 2021 (1) 2020 (1) (in millions) Profit before tax times statutory rate $ 270 $ 212 $ 160 State income taxes, net of federal benefit 8 (6) 4 U.S. research credits (14) (15) (14) U.S. share-based compensation (16) (11) (12) U.S. officers’ compensation limitation 8 6 5 Current U.S. tax on foreign earnings 53 58 39 U.S. benefit on foreign sales (17) (16) (8) Foreign earnings taxed at different rates (115) (100) (59) Deferred taxes on foreign earnings not considered indefinitely reinvested (9) 1 8 Change in unrecognized tax benefits (26) 17 8 Acquired entity integration — (15) — Release of foreign valuation allowance — (17) — Other, net 19 2 3 Provision for income taxes $ 161 $ 116 $ 134 Effective tax rate 13 % 11 % 18 % (1) The prior year amounts presented in the table above have been reclassified to conform with the current year presentation. The effective tax rate was 13 percent, 11 percent, and 18 percent for 2022, 2021 and 2020, respectively. The tax rate in each of these years was lower than the U.S. statutory rate primarily due to the proportion of worldwide earnings that are taxed at lower statutory tax rates in non-U.S. jurisdictions, partially offset by U.S. tax imposed on earnings in non-U.S. jurisdictions. The increase in the effective tax rate from 2021 to 2022 was due to nonrecurring tax benefits recorded in 2021, partially offset by a decrease in 2022 taxes from changes in tax reserves primarily due to audit settlement and from a relative decrease in U.S. tax due on non-U.S. earnings. The 2022 tax expense also includes a decrease in tax expense resulting from an out-of-period adjustment to tax reserves for fiscal years 2019 through 2021 related to the potential U.S. benefit associated with the future resolution of non-U.S. tax reserves. The 2022 decrease in tax expense was partially offset by an increase to tax expense resulting from an out-of-period adjustment related to corrections to the tax rate applied to non-US pension deferred tax balances. Neither of these out-of-period adjustments were material individually or in the aggregate. The 2021 significant nonrecurring tax benefits include the release of valuation allowance on Netherlands net operating losses in 2021 and a decrease due to the 2021 actual tax impact of acquired entity integration as compared to the estimate at acquisition based on the finalization of the integration plan. The decrease in the effective tax rate from 2020 to 2021 was due to a change in the jurisdictional mix of non-U.S. earnings offset by an increase in U.S. taxes on non-U.S. earnings and the 2021 nonrecurring tax benefits described above. Keysight benefits from tax incentives in several jurisdictions, most significantly in Singapore and Malaysia, that will expire or require renewal at various times in the future. These tax incentives provide lower rates of taxation on certain classes of income and require thresholds of investments and employment in those jurisdictions. The Singapore tax incentive is due for renewal in 2024, and the Malaysia incentive is due for renewal in 2025. We are continuing to evaluate renewal options and the impact of potential outcomes on our effective tax rate. The impact of the tax incentives decreased income taxes by $81 million, $70 million and $53 million in 2022, 2021 and 2020, respectively. The benefit of the tax incentives on net income per share (diluted) was approximately $0.45, $0.38 and $0.28 in 2022, 2021 and 2020, respectively. The increase in tax benefit from 2021 to 2022 is primarily due to a change in the jurisdictional mix of non-U.S. earnings, which increased the earnings taxed at incentive tax rates in 2022. The breakdown between current and long-term income tax assets and liabilities, excluding deferred tax assets and liabilities, was as follows for the years 2022 and 2021: October 31, 2022 2021 (in millions) Current income tax assets (included within other current assets) $ 49 $ 30 Current income tax liabilities (included within income and other taxes payable) (58) (44) Long-term income tax assets (included within other assets) 26 — Long-term income tax liabilities (included within other long-term liabilities) (190) (219) Total $ (173) $ (233) The calculation of our tax liabilities involves uncertainties in the application of complex tax law and regulations in a multitude of jurisdictions. Although the guidance on the accounting for uncertainty in income taxes prescribes the use of a recognition and measurement model, the determination of whether an uncertain tax position has met those thresholds will continue to require significant judgment by management. In accordance with the guidance on the accounting for uncertainty in income taxes, for all U.S. and other tax jurisdictions, we recognize potential liabilities for anticipated tax audit issues based on our estimate of whether, and the extent to which, additional taxes and interest will be due. We include interest and penalties related to unrecognized tax benefits within the provision for income taxes in the consolidated statements of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheet. The aggregate changes in the balances of our unrecognized tax benefits including all federal, state and foreign tax jurisdictions are as follows: 2022 2021 (1) 2020 (1) (in millions) Gross Balance, beginning of year $ 249 $ 237 $ 226 Additions for tax positions related to the current year 32 19 13 Additions for tax positions from prior years 5 — 2 Reductions for tax positions from prior years (25) (2) (2) Settlements with taxing authorities (3) — — Statute of limitations expirations (4) (4) (3) Impact from currency fluctuations (20) (1) 1 Gross Balance, end of year $ 234 $ 249 $ 237 (1) The prior year amounts presented in the table above have been reclassified to conform with the current year presentation. As of October 31, 2022, the total amount of gross unrecognized tax benefits, excluding interest and penalties, was $234 million, of which, if recognized, $178 million would impact our effective tax rate. However, approximately $2 million of the unrecognized tax benefits were related to acquisitions, which if recognized within certain agreed upon time periods, would result in the recognition of an offsetting indemnification asset. Cumulatively, interest and penalties accrued as of the end of October 31, 2022, 2021 and 2020 were $36 million, $37 million and $33 million, respectively. We recognized tax expense of $3 million, $4 million, and $5 million for interest and penalties related to unrecognized tax benefits in 2022, 2021 and 2020, respectively. There was $4 million of decrease in interest and penalties related to unrecognized tax benefits in 2022 related to currency fluctuations. The open tax years for the U.S. federal income tax return and most state income tax returns are from November 1, 2017 through the current tax year. For the majority of our foreign entities, the open tax years are from November 1, 2017 through the current tax year. For certain foreign entities, the tax years remain open, at most, back to the year 2008. Keysight’s fiscal year 2018 U.S. federal income tax return was under examination by the Internal Revenue Service. The Tax Cuts and Jobs Act was enacted in December 2017 and imposed a one-time U.S. tax on foreign earnings not previously repatriated to the U.S., known as the Transition Tax, which was reported in Keysight’s fiscal year 2018 U.S. federal income tax return. As of June 2022, the fiscal year 2018 U.S. federal income tax audit was effectively settled with no material assessments and no additional cash taxes paid. The company is being audited in Malaysia for the 2008 tax year. This tax year predates our separation from Agilent. However, pursuant to the agreement between Agilent and Keysight pertaining to tax matters, as finalized at the time of separation, for certain entities, including Malaysia, any historical tax liability is the responsibility of Keysight. In the fourth quarter of 2017, Keysight paid income taxes and penalties of $68 million on gains related to intellectual property rights. The company believes there are numerous defenses to the current assessment; the statute of limitations for the fiscal year 2008 in Malaysia was closed, and the income in question is exempt from tax in Malaysia. The company is disputing this assessment and pursuing all avenues to resolve this issue favorably for the company. Our appeals to both the Special Commissioners of Income Tax and the High Court in Malaysia have been unsuccessful. We have filed a Notice of Appeal with the Court of Appeal, and a hearing is currently scheduled for 2023. At this time, management does not believe that the outcome of any future or currently ongoing examination will have a material impact on our consolidated financial statements. We believe that we have an adequate provision for any adjustments that may result from tax examinations. However, the outcome of tax examinations cannot be predicted with certainty. Given the numerous tax years and matters that remain subject to examination in various tax jurisdictions, the ultimate resolution of current and future tax examinations could be inconsistent with management’s current expectations. If that were to occur, it could have an impact on our effective tax rate in the period in which such examinations are resolved.

GOODWILL AND OTHER INTANGIBLE ASSETS	7. GOODWILL AND OTHER INTANGIBLE ASSETS The goodwill balances as of October 31, 2022, 2021 and 2020 and the movements in 2022 and 2021 for each of our reportable segments were as follows: CSG EISG Total (in millions) Goodwill at October 31, 2020 $ 984 $ 553 $ 1,537 Foreign currency translation impact (15) 6 (9) Goodwill arising from acquisitions 100 — 100 Goodwill at October 31, 2021 1,069 559 1,628 Foreign currency translation impact (56) (10) (66) Goodwill arising from acquisitions 9 11 20 Goodwill at October 31, 2022 $ 1,022 $ 560 $ 1,582 There were no impairments of goodwill during the years ended October 31, 2022, 2021 and 2020. As of October 31, 2022, 2021 and 2020, accumulated impairment losses on goodwill were $709 million. Other intangible assets as of October 31, 2022 and 2021 consisted of the following: October 31, 2022 October 31, 2021 Gross Carrying Amount Accumulated Amortization Net Book Value Gross Accumulated Net Book (in millions) Developed technology $ 992 $ 914 $ 78 $ 969 $ 866 $ 103 Backlog 17 17 — 17 17 — Trademark/Tradename 36 31 5 36 28 8 Customer relationships 393 287 106 389 235 154 Total amortizable intangible assets 1,438 1,249 189 1,411 1,146 265 In-Process R&D — — — 7 — 7 Total $ 1,438 $ 1,249 $ 189 $ 1,418 $ 1,146 $ 272 In 2022, we recorded additions to goodwill and other intangible assets of $20 million and $23 million, respectively, due to acquisition activity. In 2021, we recorded additions to goodwill and other intangible assets of $100 million and $83 million, respectively, due to the acquisition of Sanjole and two other acquisitions. For additional information on the acquisitions, see Note 2, "Acquisitions." During the year ended October 31, 2022, we transferred $7 million from in-process R&D to developed technology as projects were successfully completed. For the year ended October 31, 2022, other intangible assets decreased $3 million due to impact of foreign currency translation. Amortization of other intangible assets was $103 million in 2022, $174 million in 2021 and $220 million in 2020. Estimated intangible assets amortization expense for each of the five succeeding fiscal years is as follows: Amortization expense (in millions) 2023 $ 82 2024 $ 43 2025 $ 25 2026 $ 16 2027 $ 9 Thereafter $ 14 Goodwill is assessed for impairment on a reporting unit basis at least annually in the fourth quarter, as of September 30, after the annual update to our long-term financial forecasts during our strategic planning cycle, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. The impairment test compares the fair value of a reporting unit with its carrying amount, with an impairment charge recorded for the amount by which the carrying amount exceeds the reporting unit’s fair value up to a maximum amount of the goodwill balance for the reporting unit. As defined in the authoritative guidance, a reporting unit is an operating segment or one level below an operating segment. We determine fair values for each of the reporting units using the market approach, when available and appropriate, or the income approach, or a combination of both. If multiple valuation methodologies are used, the results are weighted appropriately. Valuations using the market approach are derived from metrics of publicly traded comparable companies. The selections of comparable businesses are based on the markets in which our reporting units operate, giving consideration to risk profiles, size, geography, and diversity of products and services. Under the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. We use our internal forecasts to estimate future cash flows and include an estimate of long-term future growth rates based on our most recent views of the long-term outlook for each business. During the fourth quarter of 2022, we performed our annual impairment test of goodwill for all our reporting units using a qualitative approach. Based on the results of our qualitative testing, we believe that it is more-likely-than-not that the fair value of each reporting unit is greater than its respective carrying value. As of October 31, 2022, we determined that no goodwill impairment exists and that the remaining goodwill is recoverable for all of our reporting units; however, there can be no assurance that goodwill will not be impaired in future periods. Estimating the fair value of reporting units requires the use of estimates and significant judgments that are based on a number of factors including actual operating results. It is possible that the judgments and estimates described above could change in future periods. In 2021, we performed our annual impairment test of goodwill for all our reporting units using a qualitative approach, except for our previous Eggplant reporting unit, which is included in our EISG reportable segment, for which the test was performed using a quantitative approach. The income and market approaches were used to determine the fair value of the Eggplant reporting unit. With respect to the income approach, the discounted cash flow method was used, which included a forecasted cash flow projection and an estimated terminal value. The market approach used revenue, gross margin and EBITDA multiples to develop an estimate of fair value. A weighting of 75 percent and 25 percent was applied to the income and market approaches, respectively, to determine the fair value of the Eggplant reporting unit. The income approach was given a larger weighting based on the underlying detailed financial projections prepared during the strategic planning cycle that reflect the financial and operational facts and circumstances specific to Eggplant as of the valuation date. Based on the results of our annual impairment tests, the fair value of each of our reporting units exceeded the carrying value. In 2020, we performed our annual impairment test of goodwill for all our reporting units using a qualitative approach. Based on the results of our annual impairment tests, the fair value of each of our reporting units exceeded the carrying value. We review long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. We performed an impairment test of Eggplant long-lived assets in 2021 that preceded the quantitative test of goodwill in accordance with the guidance, and concluded that no impairment charge was required.

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	8. FAIR VALUE MEASUREMENTS The authoritative guidance defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market and assumptions that market participants would use when pricing the asset or liability. Fair Value Hierarchy The guidance establishes a fair value hierarchy that prioritizes inputs used in valuation techniques into three levels. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There are three levels of inputs that may be used to measure fair value: Level 1 — applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Level 2 — applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, for the asset or liability such as: quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in less active markets; or other inputs that can be derived principally from, or corroborated by, observable market data. Level 3 — applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Financial assets and liabilities measured at fair value on a recurring basis as of October 31, 2022 and 2021 were as follows: Fair Value Measurements as of October 31, 2022 2021 Total Level 1 Level 2 Level 3 Other Total Level 1 Level 2 Level 3 Other (in millions) Assets: Short-term Cash equivalents Money market funds $ 1,338 $ 1,338 $ — $ — $ — $ 1,296 $ 1,296 $ — $ — $ — Derivative instruments (foreign exchange contracts) 21 — 21 — — 6 — 6 — — Long-term Derivative instruments (interest rate swaps) 133 — 133 — — 48 — 48 — — Equity investments 50 50 — — — 60 60 — — — Investments - other 12 — — — 12 10 — — — 10 Total assets measured at fair value $ 1,554 $ 1,388 $ 154 $ — $ 12 $ 1,420 $ 1,356 $ 54 $ — $ 10 Liabilities: — Short-term Derivative instruments (foreign exchange contracts) $ 12 $ — $ 12 $ — $ — $ 4 $ — $ 4 $ — $ — Long-term Deferred compensation liability 22 — 22 — — 24 — 24 — — Total liabilities measured at fair value $ 34 $ — $ 34 $ — $ — $ 28 $ — $ 28 $ — $ — During the year ended October 31, 2022, we made investments of $33 million, including an equity investment of $30 million. The changes in fair value of the equity investment are recorded within "other income (expense), net" in the consolidated statement of operations. Our money market funds and equity investments with readily determinable fair values are measured at fair value using quoted market prices and, therefore, are classified within Level 1 of the fair value hierarchy. Equity or fixed income investments without readily determinable fair values that are measured at cost adjusted for observable changes in price or impairments and convertible notes are not categorized in the fair value hierarchy and are presented as "Investments - other" in the tables above. Our deferred compensation liability is classified as Level 2 because the inputs used in the calculations are observable, although the values are not directly based on quoted market prices. Our derivative financial instruments are classified within Level 2 as there is not an active market for each hedge contract, but the inputs used to calculate the value of the instruments are tied to active markets. Equity investments, including securities that are earmarked to pay the deferred compensation liability, and the deferred compensation liability are reported at fair value, with gains or losses resulting from changes in fair value recognized in earnings. Certain derivative instruments are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income (loss). All of our investments are subject to periodic impairment review. The impairment analysis requires judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of the investment. There was no impairment recognized in 2022, 2021 and 2020. Realized gains and losses from the sale of investments are recorded in earnings. Net unrealized gain (loss) on investments still held was a loss of $36 million in 2022 as compared to gains of $4 million and $11 million in 2021 and 2020, respectively. There were no realized gains or losses from the sale of investments in 2022, 2021 and 2020. Financial Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis Assets measured at fair value on a non-recurring basis consisted of goodwill and intangible assets. See Note 7, "Goodwill and Other Intangible Assets" for more information. Goodwill Fair value assessments of the reporting unit and the reporting unit's net assets, which are performed for goodwill impairments tests, are considered Level 3 measurements due to the significance of unobservable inputs developed using company-specific information. In the event of performing a quantitative impairment test, we consider a market approach as well as an income approach using the discounted cash flow model to determine the fair value of the reporting unit. Intangible Assets We utilized an income approach for estimating the fair value of intangible assets. The future cash flows used in the analysis are based on internal cash flow projections based on our long-range plans and include significant assumptions by management. Accordingly, the fair value assessment of the long-lived assets is considered a Level 3 fair value measurement. Long Lived Assets For the year ended 2022, our held and used long-lived assets in Russia with a carrying amount of $3 million were written down to a fair value of zero, resulting from an impairment of assets that were expected to generate zero cash flows in the future, and was recorded within “other operating expense (income), net” in the consolidated statement of operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	9. DERIVATIVES We are exposed to foreign currency exchange rate fluctuations and interest rate changes in the normal course of our business. As part of our risk management strategy, we use derivative instruments, which are primarily forward contracts, to hedge economic and/or accounting exposures resulting from changes in foreign currency exchange rates. Cash Flow Hedges We enter into foreign exchange contracts to hedge our forecasted operational cash flow exposures resulting from changes in foreign currency exchange rates. These foreign exchange contracts, carried at fair value, have maturities based on a rolling period of up to twelve months. These derivative instruments are designated and qualify as cash flow hedges under the criteria prescribed in the authoritative guidance. The changes in the value of the derivative instrument included in the assessment of effectiveness are recognized in accumulated other comprehensive income and reclassified into earnings when the forecasted transaction occurs in the same financial statement line item in the consolidated statement of operations where the earnings effect of the hedged item is presented. If it becomes probable that the forecasted transaction will not occur, the hedge relationship will be de-designated and amounts accumulated in other comprehensive income will be reclassified into earnings in the current period. Gains and losses on the derivative instrument representing hedge components excluded from the assessment of effectiveness are amortized to earnings on a straight-line basis over the tenor of the hedge and are presented in the same financial statement line of the consolidated statement of operations where the earnings effect of the hedged item is presented. For hedges executed prior to February 1, 2020, these gains and losses were recognized immediately in earnings. In 2020, we entered into forward-starting interest rate swaps with an aggregate notional amount of $600 million associated with future interest payments on anticipated debt issuances through 2024. The contract term allows us to lock-in a treasury rate on anticipated debt issuances. These derivative instruments are designated and qualify as cash flow hedges under the criteria prescribed in the authoritative guidance. The changes in fair value of these derivative instruments have been recognized in accumulated other comprehensive income (loss). For the year ended October 31, 2022, a gain of $85 million was recognized in accumulated other comprehensive income (loss). Amounts associated with these cash flow hedges will be reclassified to interest expense in the consolidated statement of operations when future interest payments on the anticipated debt occur. Other Hedges Additionally, we enter into foreign exchange contracts to hedge monetary assets and liabilities that are denominated in currencies other than the functional currency of our subsidiaries. These foreign exchange contracts are carried at fair value and do not qualify for hedge accounting treatment and are not designated as hedging instruments. Changes in value of the derivative are recognized in other income (expense), net, in the consolidated statement of operations, in the current period, along with the offsetting foreign currency gain or loss on the underlying assets or liabilities. Our use of derivative instruments exposes us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We do, however, seek to mitigate such risks by limiting our counterparties to major financial institutions, which are selected based on their credit ratings and other factors. We have established policies and procedures for mitigating credit risk that include establishing counterparty credit limits, monitoring credit exposures, and continually assessing the creditworthiness of counterparties. The number of open foreign exchange forward contracts designated as "cash flow hedges" and "not designated as hedging instruments" was 212 and 74, respectively, as of October 31, 2022. The aggregated notional amounts by currency and designation as of October 31, 2022 were as follows: Derivatives in Cash Flow Hedging Relationships Derivatives Not Designated as Hedging Instruments Forward Contracts Forward Contracts Currency Buy/(Sell) Buy/(Sell) (in millions) Euro $ 11 $ 4 British Pound 20 (28) Singapore Dollar 29 34 Malaysian Ringgit 110 9 Japanese Yen (150) (47) Other currencies (8) (28) Total $ 12 $ (56) Derivative instruments are subject to master netting arrangements and are disclosed at their gross fair value in the consolidated balance sheet.

Leases [Abstract]
Lessee, Operating Leases [Text Block]	10. LEASES We have operating leases for items including office space, manufacturing and production locations, sales and service centers, research and development facilities and certain equipment, primarily automobiles. Our leases have remaining terms of up to 15 years, which represent the non-cancellable periods of the leases and include extension options that we determined are reasonably certain to be exercised. The weighted average lease term of our operating leases was 7.7 years, 8.2 years and 7.3 years as of October 31, 2022, 2021 and 2020, respectively. The weighted average discount rate of our operating leases was 3 percent as of October 31, 2022, 2021 and 2020. The following table summarizes the components of our lease cost: Year ended October 31, 2022 2021 2020 (in millions) Operating lease cost $ 51 $ 51 $ 49 Variable lease cost $ 17 $ 14 $ 16 Short-term lease costs, sublease income and finance lease costs were immaterial for the year ended October 31, 2022, 2021 and 2020. Right-of-use (“ROU”) asset impairments were $2 million in 2022 related to the discontinuance of our Russia operations. Supplemental cash flow information related to our operating leases was as follows: Year ended October 31, 2022 2021 2020 (in millions) Cash payments for operating leases $ 51 $ 53 $ 48 ROU assets obtained in exchange for operating lease obligations $ 51 $ 78 $ 67 The decrease in ROU assets obtained in exchange for operating lease obligations was primarily driven by reassessment of a lease term in the prior year triggered by significant leasehold improvements. The maturities of our operating leases as of October 31, 2022 with initial terms exceeding one year were as follows: Operating Leases (in millions) 2023 $ 45 2024 37 2025 30 2026 27 2027 25 Thereafter 87 Total undiscounted lease liability 251 Imputed interest 26 Total discounted lease liability $ 225 As of October 31, 2022, we have additional operating leases, primarily for real estate, that have not yet commenced of $20 million. These operating leases will commence in 2023 with lease terms of up to 15 years. Rental income from the lease of excess facilities was $11 million for the year ended October 31, 2022, 2021 and 2020 and is included in other operating expense (income), net. Other lessor arrangements were immaterial.

Retirement Benefits [Abstract]
RETIREMENT PLANS AND POST-RETIREMENT PENSION PLANS	12. RETIREMENT PLANS AND POST-RETIREMENT BENEFIT PLANS General. The majority of our employees are covered under various defined benefit and/or defined contribution retirement plans. Additionally, we sponsor post-retirement health care benefits for our eligible U.S. employees. We provide U.S. employees who meet eligibility criteria under the Keysight Technologies, Inc. Retirement Plan ("RP") defined benefits that are based on an employee's base or target pay during the years of employment and on length of service. For eligible employees' service through October 31, 1993, the benefit payable under the RP is reduced by any amounts due to the eligible employees' service under our defined contribution Deferred Profit-Sharing Plan ("DPSP"), which was closed to new participants as of November 1993. The obligations under the DPSP equal the fair value of the DPSP assets, which was $177 million as of October 31, 2022. Employees hired on or after August 1, 2015 are not eligible to participate in the RP or the Keysight Technologies, Inc. Health Plan for Retirees ("U.S. Post-Retirement Benefit Plan"). In addition, in the U.S. we maintain the Supplemental Benefits Retirement Plan ("SBRP"), a supplemental unfunded non-qualified defined benefit plan to provide benefits that would be provided under the RP but for limitations imposed by the Internal Revenue Code. The RP and the SBRP comprise the "U.S. Plans." Eligible employees outside the U.S. generally receive retirement benefits under various retirement plans ("Non-U.S. Plans") based on factors such as years of service and/or employee compensation levels. Eligibility is generally determined in accordance with local statutory requirements. Certain of our immaterial non-U.S. defined benefit plans are not included in these disclosures. 401(k) defined contribution plan. Eligible U.S. employees may participate in the Keysight Technologies, Inc. 401(k) Plan (the "401(k) Plan"). Enrollment in the 401(k) Plan is automatic for employees who meet eligibility requirements unless they decline participation. We provide matching contributions of up to 4 percent of annual eligible compensation for employees hired prior to August 1, 2015 and up to 6 percent for employees hired thereafter. The 401(k) Plan employer expense included in income from operations was $31 million in 2022, $28 million in 2021 and $27 million in 2020. Post-retirement medical benefit plans. In addition to receiving retirement benefits, U.S. employees who meet eligibility requirements as of their termination date may participate in the U.S. Post-Retirement Benefit Plans. Components of net periodic benefit cost. We record the service cost component of net periodic benefit cost (benefit) in the same line item as other employee compensation costs. We record the non-service components of net periodic benefit cost (benefit), such as interest cost, expected return on assets, amortization of prior service cost, and actuarial gains or losses, within "other income (expense), net" in the consolidated statement of operations. The company uses alternate methods of amortization, as allowed by the authoritative guidance, which amortizes the actuarial gains and losses on a consistent basis for the years presented. For the U.S. Plans, gains and losses are amortized over the average future working lifetime. For most Non-U.S. Plans and the U.S. Post-Retirement Benefit Plan, gains and losses are amortized using a separate layer for each year's gains and losses. During the years ended October 31, 2022 and 2020, the lump-sum payments in our U.K. defined benefit plan were more than the sum of the service cost and interest cost components of net periodic benefit cost (“the threshold amount”), resulting in the recognition of settlement losses of $9 million and $5 million, respectively. In March 2021, we transferred substantially all the assets and obligations of our Netherlands defined benefit plan to an insurance company. This partial settlement resulted in a a net refund of $3 million and a loss of $16 million for the year 2021, which is included in "other income (expense), net" in the consolidated statement of operations. We recognized a curtailment gain of $1 million in our Netherlands defined benefit plan for the year 2020, also included in "other income (expense), net" in the consolidated statement of operations. For the years ended October 31, 2022, 2021 and 2020, components of net periodic benefit cost (benefit) and other amounts recognized in other comprehensive income were comprised of: Defined Benefit Plans U.S. Post-Retirement Benefit Plan U.S. Plans Non-U.S. Plans 2022 2021 2020 2022 2021 2020 2022 2021 2020 (in millions) Net periodic benefit cost (benefit) Service cost — benefits earned during the period $ 25 $ 24 $ 23 $ 13 $ 15 $ 15 $ 1 $ 1 $ 1 Interest cost on benefit obligation 23 22 24 15 15 16 5 4 6 Expected return on plan assets (61) (52) (44) (58) (77) (84) (14) (12) (13) Amortization: Net actuarial loss 11 24 18 24 41 34 1 11 10 Prior service credit — — — — (1) (1) (11) Net periodic benefit cost (benefit) (2) 18 21 (6) (6) (19) (8) 3 (7) Curtailments and settlements — — — 9 16 4 — — — Total periodic benefit cost (benefit) $ (2) $ 18 $ 21 $ 3 $ 10 $ (15) $ (8) $ 3 $ (7) Other changes in plan assets and benefit obligations recognized in other comprehensive (income) loss Net actuarial loss (gain) $ (9) $ (100) $ 64 $ (38) $ 26 $ 81 $ 17 $ (38) $ 9 Amortization: Net actuarial loss (11) (24) (18) (24) (41) (34) (1) (11) (10) Prior service credit — — — — — — 1 1 11 Curtailments and settlements — — — (9) (16) (4) — — — Foreign currency — — — (6) 1 1 — — — Total recognized in other comprehensive (income) loss $ (20) $ (124) $ 46 $ (77) $ (30) $ 44 $ 17 $ (48) $ 10 Total recognized in the periodic benefit cost (benefit) and other comprehensive (income) loss $ (22) $ (106) $ 67 $ (74) $ (20) $ 29 $ 9 $ (45) $ 3 Funded status.

The change in the benefit obligations for the U.S. post-retirement benefit plan was primarily driven by changes in the discount rate. Investment policies and strategies as of October 31, 2022 . In the U.S., our RP and U.S. Post-Retirement Benefit Plan target asset allocations are approximately 70 percent to equities, including growth-seeking, and approximately 30 percent to fixed income investments. Our DPSP target asset allocation is approximately 60 percent to equities and approximately 40 percent to fixed income investments. The general investment objective for all our plan assets is to obtain the optimum rate of investment return on the total investment portfolio consistent with the assumed level of risk. Specific investment objectives for the plans' portfolios are to: maintain and enhance the purchasing power of the plans' assets; achieve investment returns consistent with the level of risk being taken; and earn performance rates of return in accordance with the benchmarks adopted for each asset class. Outside of the U.S., our target asset allocation is from 7 to 70 percent to equities, from 30 to 51 percent to fixed income investments, and from zero to 64 percent to insurance contracts and cash. All plans' assets are broadly diversified. Due to fluctuations in capital markets, our actual allocations of plan assets as of October 31, 2022 may differ from the target allocation. Our policy is to periodically bring the actual allocation in line with the target allocation. Equity securities include exchange-traded common stock and preferred stock of companies from broadly diversified industries. Fixed income securities include a portfolio of corporate bonds of companies from diversified industries, government securities, mortgage-backed securities, asset-backed securities, derivative instruments and other. Portions of the cash and cash equivalent, equity, and fixed income investments are held in commingled funds. Investments in commingled funds are valued using the net asset value (“NAV”) method as a practical expedient. Investments valued using the NAV method are allocated across a broad array of funds and diversify the portfolio. The value of the plan assets directly affects the funded status of our pension and post-retirement benefit plans recorded in the financial statements. In March 2021, we entered into an insurance buy-in contract for a portion of benefit obligations under the U.K. defined benefit plan. In December 2021, we completed the second phase of the same contract and classified it as “Other Investment.” The insurance buy-in contract is similar to an annuity contract, which matches cash flows with future benefit payments for a specific group of pensioners with the obligation remaining with the plan. This contract is issued by a third-party insurance company with no affiliation to us. The insurance contract is valued on an insurer pricing basis, which reflects the purchase price adjusted for changes in discount rates and other actuarial assumptions, which approximates fair value. Fair Value . The measurement of the fair value of pension and post-retirement plan assets uses the valuation methodologies and the inputs as described in Note 8, "Fair Value Measurements." Cash and Cash Equivalents - Cash and cash equivalents consist of short-term investment funds that are invested in short-term domestic fixed income securities and other securities with debt-like characteristics, emphasizing short-term maturities and quality. Cash and cash equivalents are generally classified as Level 2 investments except when the cash and cash equivalents are held in commingled funds, which have a daily NAV derived from quoted prices for the underlying securities in active markets; these are classified as assets measured at NAV. Equity - Some equity securities consisting of common and preferred stock are held in commingled funds, which have daily NAVs derived from quoted prices for the underlying securities in active markets; these are classified as assets measured at NAV. Commingled funds that have quoted prices in active markets are classified as Level 1 investments. Equity also includes some growth-seeking real estate commingled funds that are measured at NAV. Fixed Income - Some of the fixed income securities are held in commingled funds that have daily NAVs derived from the underlying securities; these are classified as assets measured at NAV. Commingled funds that have quoted prices in active markets are classified as Level 1 investments. Other Investment - Other investment represents the U.K. insurance buy-in contract and is classified as a Level 3 investment. Insurance contracts are generally classified as Level 3 investments.

For 2023, we do not expect to contribute to our U.S. Defined Benefit Plan or U.S. Post-Retirement Benefit Plan, and we expect to contribute $11 million to our Non-U.S. Defined Benefit Plans. The following table presents expected future benefit payments for the next 10 years. U.S. Defined Non-U.S. Defined U.S. Post-Retirement (in millions) 2023 $ 50 $ 38 $ 14 2024 $ 51 $ 40 $ 15 2025 $ 60 $ 41 $ 15 2026 $ 59 $ 42 $ 16 2027 $ 61 $ 44 $ 16 2028 - 2032 $ 298 $ 233 $ 72 Assumptions . The assumptions used to determine the benefit obligations and net periodic benefit cost for our defined benefit and post-retirement benefit plans are presented in the tables below. The expected long-term return on assets below represents an estimate of long-term returns on investment portfolios, consisting of a mixture of equities, fixed income and other investments, in proportion to the asset allocations of each of our plans. We consider long-term rates of return, which are weighted based on the asset classes (both historical and forecasted) in which we expect our pension and post-retirement funds to be invested. Discount rates reflect the current rate at which pension and post-retirement obligations could be settled based on the measurement dates of the plans, which is October 31. The U.S. discount rates as of October 31, 2022 and 2021 were determined based on the results of matching expected plan benefit payments with cash flows from a hypothetically constructed bond portfolio. The Non-U.S. discount rates as of October 31, 2022 and 2021 were determined based on a granular approach, which discounts the expected plan benefit payments with rates from a high-quality corporate bond yield curve. In addition, we used this method to calculate two components of the periodic benefit cost: service cost and interest cost. The range of assumptions that were used for the Non-U.S. Defined Benefit Plans reflects the different economic environments within various countries. Assumptions used to calculate the net periodic benefit cost (benefit) were as follows: Year ended October 31, 2022 2021 U.S. Defined Benefit Plans: Discount rate 2.75% 2.75% Average increase in compensation levels 3.50% 3.00% Expected long-term return on assets 7.25% 7.50% Non-U.S. Defined Benefit Plans: Discount rate 0.70-1.86% 0.81-1.66% Average increase in compensation levels 2.50-2.75% 2.50-2.75% Expected long-term return on assets 3.00-6.50% 4.00-6.50% U.S. Post-Retirement Benefits Plan: Discount rate 2.75% 2.25% Expected long-term return on assets 7.25% 7.50% Current medical cost trend rate 6.00% 6.25% Ultimate medical cost trend rate 4.50% 4.50% Medical cost trend rate decreases to ultimate rate in year 2028 2028 Assumptions used to calculate the benefit obligation as of October 31, 2022 and 2021 were as follows: Year ended October 31, 2022 2021 U.S. Defined Benefit Plans: Discount rate 6.00% 2.75% Average increase in compensation levels 3.50% 3.50% Non-U.S. Defined Benefit Plans: Discount rate 1.87-4.22% 0.70-1.86% Average increase in compensation levels 2.50-3.00% 2.50-2.75% U.S. Post-Retirement Benefits Plan: Discount rate 6.00% 2.75% Current medical cost trend rate 7.00% 6.00% Ultimate medical cost trend rate 4.75% 4.50% Medical cost trend rate decreases to ultimate rate in year 2029 2028 Health care trend rates did not have a significant effect on the total service and interest cost components or on the post-retirement benefit obligation amounts reported for the U.S. Post-Retirement Benefit Plan for the years ended October 31, 2022 and 2021.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	14. COMMITMENTS AND CONTINGENCIES Commitments to contract manufacturers and suppliers. We purchase components from a variety of suppliers and use several contract manufacturers to provide manufacturing services for our products. During the normal course of business, we issue purchase orders with estimates of our requirements several months ahead of the delivery dates. The reported open purchase orders represent a commitment to our suppliers. Our agreements with suppliers for common materials provide us with the option to cancel, reschedule, and adjust our requirements based on business needs. We expect to fulfill most of our purchase commitments for inventory within one year or based on mutually agreed terms. As of October 31, 2022 and 2021, our non-cancellable purchase commitments were approximately $553 million and $444 million, respectively, of which the majority is for less than one year. The increase in non-cancellable purchase commitments for the year ended October 31, 2022, was driven by higher revenue and advance purchase orders to secure capacity for critical parts due to global supply chain constraints. Other purchase commitments. Other purchase commitments relate to contracts with professional services suppliers. We can typically cancel these contracts within 90 days without penalties. For those contracts that are not cancellable within 90 days without penalties, we disclose the amounts we are obligated to pay to a supplier under each contract in that period before such contract can be canceled. As of October 31, 2022, our contractual obligations with these suppliers were approximately $55 million within the next fiscal year, as compared to approximately $60 million as of October 31, 2021. Litigation and Contingencies. On August 3, 2021, we entered into a Consent Agreement with the Directorate of Defense Trade Controls, Bureau of Political-Military Affairs, Department of State to resolve alleged violations of the Arms Export Control Act and the International Traffic in Arms Regulations ("ITAR"). Pursuant to the Consent Agreement, we were assessed a penalty of $6.6 million to be paid over three years, $2.5 million of which was suspended and designated for remediation activities over three years, including employment of a special compliance officer. To date, we have paid $2.1 million of the penalty. The suspended portion of the penalty has been satisfied by amounts we have spent on qualifying compliance activities to date. On January 1, 2022, Centripetal Networks filed a lawsuit in Federal District Court in Virginia, alleging that certain Keysight products infringe certain of Centripetal’s patents. In addition, in February 2022 Centripetal filed complaints in Germany alleging infringement of certain of Centripetal’s German patents, and in April 2022 Centripetal filed a complaint with the International Trade Commission (“ITC”) requesting that they investigate whether Keysight should be enjoined from importing certain products that are manufactured outside of the U.S. and which are alleged to infringe Centripetal patents. We deny the allegations and intend to aggressively defend each case. Although there are no matters pending that we currently believe are probable and reasonably possible of having a material impact to our business, consolidated financial position, or results of operations or cash flows, the outcome of litigation is inherently uncertain and is difficult to predict. An adverse outcome in any outstanding lawsuit or proceeding could result in significant monetary damages or injunctive relief. If adverse results are above management’s expectations or are unforeseen, management may not have accrued for the liability, which could impact our results in a financial period. We are also involved in lawsuits, claims, investigations and other proceedings, including, but not limited to, patent, commercial and environmental matters, which arise in the ordinary course of business. Indemnification Obligations Related to Transactions In connection with acquisitions, divestitures, mergers, spin-offs and other transactions, we have agreed to indemnify certain parties for future damages, losses, expenses and liabilities that were incurred prior to or are related to such transactions. The liabilities covered by these indemnifications, include but are not limited to tax, employment, benefits, intellectual property, environmental, and other liabilities. We do not believe that our indemnification obligations related to such liabilities were material as of October 31, 2022. Indemnifications to Officers and Directors Our corporate by-laws require that we indemnify our officers and directors, as well as those who act as directors and officers of other entities at our request, against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services to Keysight and such other entities, including service with respect to employee benefit plans. In addition, we have entered into separate indemnification agreements with each director and each board-appointed officer of Keysight that provide for indemnification under similar and additional circumstances. The indemnification obligations are more fully described in our corporate by-laws and the indemnification agreements, which are available on our website. We purchase standard insurance to cover claims or a portion of the claims made against our directors and officers. Since a maximum obligation is not explicitly stated in our by-laws or in our indemnification agreements and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated. We have not historically made payments related to these obligations, and do not believe that our indemnification obligations related to such claims were material as of October 31, 2022. Other Indemnifications As is customary in our industry and as provided for in local law in the U.S. and other jurisdictions, many of our standard contracts provide remedies to our customers and others with whom we enter into contracts, such as defense, settlement, or payment of judgment for intellectual property claims related to the use of our products. From time to time we indemnify customers, as well as our suppliers, contractors, lessors, lessees, companies that purchase our businesses or assets and others with whom we enter into contracts, against combinations of loss, expense, or liability arising from various triggering events related to the sale and the use of our products and services, the use of their goods and services, the use of facilities and state of our owned facilities, the state of the assets and businesses that we sell and other matters covered by such contracts, usually up to a specified maximum amount. In addition, from time to time we also provide protection to these parties against claims related to undiscovered liabilities, additional product liability or environmental obligations. In our experience, claims made under such indemnifications are rare and we do not believe that our indemnification obligations related to such claims were material as of October 31, 2022.

STOCKHOLDERS' EQUITY	15. STOCKHOLDERS' EQUITY Stock Repurchase Program On November 18, 2021, our board of directors approved a stock repurchase program authorizing the purchase of up to $1,200 million of the company’s common stock, replacing the previously approved November 2020 program, under which $77 million remained. Under our stock repurchase program, shares may be purchased from time to time, subject to general business and market conditions and other investment opportunities, through open market purchases, privately negotiated transactions or other means. All such shares and related costs are held as treasury stock and accounted for at the trade date using the cost method. The stock repurchase program may be commenced, suspended or discontinued at any time at the company’s discretion and does not have an expiration date. In 2022 we repurchased 5,442,280 shares of common stock for $849 million. In 2021 we repurchased 4,361,542 shares of common stock for $673 million. In 2020 we repurchased 4,274,366 shares of common stock for $410 million. All such shares and related costs are held as treasury stock and accounted for at the trade date using the cost method.

Segment Reporting [Abstract]
SEGMENT INFORMATION	16. SEGMENT INFORMATION Our operating segments were determined based primarily on how the chief operating decision maker views and evaluates our operations. Segment operating results are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to each segment and to assess performance. Other factors, including market separation and customer specific applications, go-to-market channels, products and services and manufacturing are considered in determining the formation of these operating segments. Descriptions of our two reportable segments are as follows: The Communications Solutions Group serves customers spanning the worldwide commercial communications and aerospace, defense and government end markets. The group's solutions consist of electronic design and test software, electronic measurement instruments, systems and related services. These solutions are used in the simulation, design, validation, manufacturing, installation and optimization of electronic equipment and networks. The Electronic Industrial Solutions Group provides test and measurement solutions and related services across a broad set of electronic industrial end markets, focusing on high-value applications in the automotive and energy industries and measurement solutions for consumer electronics, education, general electronics design and manufacturing, and semiconductor design and manufacturing. The group provides electronic measurement instruments, design and test software and systems, and related services used in the simulation, design, validation, manufacturing, installation and optimization of electronic equipment, as well as automated test software that uses artificial intelligence and machine learning to automate test creation and test execution. A significant portion of the segments' expenses arise from allocated corporate charges, as well as expenses related to our centralized sales force, and service, marketing and technology functions that we have historically provided to the segments in order to realize economies of scale and to efficiently use resources. Corporate charges include legal, accounting, real estate, insurance services, information technology services, treasury and other corporate infrastructure expenses. Segment allocations are determined on a basis that we consider to be a reasonable reflection of the utilization of services provided to, or benefits received by, the segments. Newly acquired businesses are not allocated these charges until integrated into our shared services and corporate infrastructure. The following tables reflect the results of our reportable segments under our management reporting system. These results are not necessarily in conformity with U.S. GAAP. The performance of each segment is measured based on several metrics, including income from operations. These results are used, in part, by the chief operating decision maker in evaluating the performance of, and in allocating resources to, each of the segments. The profitability of each of the segments is measured after excluding share-based compensation expense, amortization of acquisition-related balances, acquisition and integration costs, a 2020 gain on an insurance settlement related to northern California wildfires, restructuring costs, interest income, interest expense and other items as noted in the reconciliations below.

OVERVIEW AND SUMMARY OF SIGNI_2

OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Oct. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of Presentation. We have prepared the accompanying financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and in conformity with generally accepted accounting principles in the U.S. ("GAAP"). Our fiscal year end is October 31. Unless otherwise stated, all years and dates refer to our fiscal year. Management is responsible for the fair presentation of the accompanying consolidated financial statements, prepared in accordance with GAAP, and has full responsibility for their integrity and accuracy. In the opinion of management, the accompanying consolidated financial statements contain all normal and recurring adjustments necessary to present fairly our consolidated balance sheet and our consolidated statement of operations, statement of comprehensive income, statement of cash flows and statement of equity.
Principles of consolidation	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.
Use of estimates	Use of Estimates. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in our 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. We are not aware of any specific event or circumstance that would require an update to our estimates or judgments or a revision of the carrying value of our assets or liabilities as of October 31, 2022. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are revenue recognition, inventory valuation, share-based compensation, retirement and post-retirement plan assumptions, valuation of goodwill and other intangible assets, warranty, loss contingencies, restructuring and accounting for income taxes.
Revenue recognition	Revenue recognition. Revenue is recognized upon transfer of control of the promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We primarily generate revenue from the sale of products (hardware and/or software), services, or a combination thereof. We enter into contracts that may involve multiple performance obligations, and we allocate the transaction price between each performance obligation on the basis of relative standalone selling price ("SSP"). Revenue is recognized net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities. Product revenues are generated predominantly from the sale of various types of design and test software and hardware. Products consist of standalone software and hardware generally installed with software applications that are licensed on a perpetual and term basis. Our hardware products generally do not have any substantive acceptance terms that would otherwise preclude the transfer of control. Performance obligations related to our software licenses, including the license portion of our software subscriptions, grant the customer the right to use our software primarily via electronic delivery. Service revenues consist of repair and calibration services, extended warranties, technical support for hardware and software, when-and-if available software updates and upgrades, and professional services, including installation and implementation, consulting, and training. Services include both hardware and software services. Repair and calibration services for hardware products are sold both as per-incident customer services and as customer agreements to provide such services over the contractual period. Extended warranties are optional to the customer and provide warranty on hardware products for additional years beyond the standard one-year warranty. Technical support for software and when-and-if available software updates and upgrades are sold either together with our software licenses and software subscriptions, or separately as part of our customer support programs. These are considered stand-ready performance obligations where customers benefit from the services evenly throughout the license or service period. These performance obligations provide the customer access evenly over the contract period. Our professional services may be sold on a time and material basis (e.g., consulting) or on a fixed-fee basis (e.g., non-recurring engineering). We also generate revenues from a combination of products and services ("custom solutions"), including combinations of hardware, software, software subscriptions, installation, professional services, and other support services. Custom solutions provide the customer with a combination of hardware, software and professional services to meet customers' unique specifications and are accounted for as one performance obligation. For our contracts with customers, we account for individual performance obligations separately if they are distinct. Our standard payment terms are net 30 to 90 days, and we generally do not offer extended payment terms beyond one year. Our contracts typically contain various forms of variable consideration, including trade discounts, trade-in credits, rebates, and rights of return. The transaction price is allocated to the separate performance obligations based on relative SSP. SSPs for a majority of our products and services are estimated based on our established pricing practices and maximize the use of observable inputs. An observable input is the price of the good or service when it is sold as a separate item in a similar circumstance and to a similar customer as in the contract for which SSPs are being determined. We have elected to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by Keysight from a customer (e.g., sales, use, value added, and some excise taxes). We have also elected to account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of assessing such activities as performance obligations. Our typical performance obligations include the following: Performance obligation When performance obligation is typically satisfied When payment is typically due How standalone selling price is typically determined Product Revenues Hardware When customer obtains control of the product, typically at delivery (point in time) Within 30-90 days of shipment Estimated based on established pricing practices or observable based on standalone sales for certain hardware products Software licenses Primarily upon electronic delivery of the software, and the applicable license period has begun (point in time) Within 30-90 days of the beginning of license period Estimated based on established pricing practices or observable based on standalone sales for certain software products Software subscriptions Ratably over the subscription period (over time) Within 30-90 days of the beginning of subscription period Estimated based on established pricing practices Service Revenues Calibration contracts Ratably over the service contract period (over time) Within 30-90 days of the beginning of service contract period Estimated based on established pricing practices Repair and calibration (per- incident) As services are performed (point in time) Within 30-90 days of invoicing for services rendered Estimated based on established pricing practices Extended hardware warranty Ratably over the warranty period (over time) Within 30-90 days of invoicing Estimated based on established pricing practices or observable based on standalone sales of certain hardware warranty contracts Technical support and when-and-if-available software updates Ratably over the license service contract period (over time) Within 30-90 days of the beginning of license or service contract period Estimated based on established pricing practices or observable based on standalone sales for certain support contracts Professional services As services are performed based on measures of progress (over time) or at a point in time Within 30-90 days of invoicing for services rendered Estimated based on established pricing practices Custom Solutions Custom solutions (milestone-based; percentage-of-completion) As milestones are achieved based on transfer of control to customer (over time) Within 30-90 days of milestone achievement Transaction price, as pricing is custom and can vary significantly from contract to contract Custom solutions (point in time) When customer obtains control of the solution, typically at delivery or customer acceptance, as defined by the contract (point in time) Within 30-90 days of delivery of solution Transaction price, as pricing is custom and can vary significantly from contract to contract Significant judgment is required to determine the SSP for each distinct performance obligation. As most of our products and services are not sold on a standalone basis, we typically estimate the SSP. In doing so, we consider our internal price list for each product and service, which reflects our desired profitability, based on an expected level of sales, and adjust for factors such as competition, customer relationship, discount provided in the contract, geographic location, and the products and services purchased in the arrangement. We use a range based on actual historical sales to determine whether the calculated SSP for a product or service is a fair representation of the SSP. For capitalized contract costs, we use judgment in determining the capitalized amount and amortization period. Our products are generally sold with a right of return and we may provide other credits, discounts, or incentives, which are accounted for as variable consideration at the portfolio level and estimated based on historical information. Returns, credits, and discounts are estimated at contract inception and updated at the end of each reporting period as additional information becomes available to the extent that it is probable a significant reversal of the cumulative amount of revenue recognized will not occur once the variability is subsequently resolved. Shipping and handling costs. Our shipping and handling costs charged to customers are included in revenue, and the associated expense is recorded in cost of products for all periods presented.
Accounts receivable, net	Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Such accounts receivable have been reduced by an allowance for credit losses, which is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on customer specific experience and the aging of such receivables, among other factors. The allowance for credit losses was approximately $4 million as of both October 31, 2022 and 2021. We do not have any off-balance-sheet credit exposure related to our customers.
Share-based Payment Arrangement	We account for share-based awards made to our employees and directors, including restricted stock units ("RSUs"), employee stock purchases made under Keysight's employee stock purchase plan under Section 423(b) of the Internal Revenue Code ("ESPP"), employee stock option awards, and performance share awards under Keysight Technologies, Inc. Long-Term Performance ("the LTP") Program, using the estimated grant date fair value method of accounting. We recorded compensation expense for all share-based awards of $126 million in 2022, $104 million in 2021 and $93 million in 2020.
Inventory	Inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of market value. We assess the valuation of our inventory on a periodic basis and make adjustments to the value for estimated excess and obsolete inventory based on estimates about future demand and actual usage. The excess balance determined by this analysis becomes the basis for our excess inventory charge. Our excess inventory review process includes analysis of sales unit forecasts, managing product rollovers and working with manufacturing to maximize recovery of excess inventory.
Warranty	Keysight warranties on products sold through direct sales channels are primarily for one year. Warranties for products sold through distribution channels are primarily for three years. We accrue for standard warranty costs based on historical trends in warranty charges. The accrual is reviewed regularly and periodically adjusted to reflect changes in warranty cost estimates. Estimated warranty charges are recorded within cost of products at the time related product revenue is recognized. See Note 13, "Supplemental financial information".We also sell extended warranties that provide warranty coverage beyond the standard warranty term. Revenue associated with extended warranties is deferred and recognized over the extended coverage period.
Loss contingencies	We accrue for probable losses from contingencies, including legal settlement costs, on an undiscounted basis when such costs are considered probable of being incurred and are reasonably estimable. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary.
Taxes on income	Income tax expense is based on income or loss before taxes. Deferred income taxes reflect the effect of temporary differences between asset and liability amounts that are recognized for financial reporting purposes and the amounts that are recognized for income tax purposes. These deferred taxes are measured by applying currently enacted tax laws. Valuation allowances are recognized to reduce deferred tax assets to the amount that is more likely than not to be realized.We account for uncertainty in income taxes using a two-step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50 percent likely of being realized upon settlement. We make adjustments to these reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate due to new information. We classify the liability for unrecognized tax benefits as current to the extent that the company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, we are unable to estimate the range of possible changes to the balance of our unrecognized tax benefits.
Goodwill and other intangible assets	Goodwill is assessed for impairment on a reporting unit basis at least annually in the fourth quarter, as of September 30, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. The impairment test compares the fair value of a reporting unit with its carrying amount, with an impairment charge recorded for the amount by which the carrying amount exceeds the reporting unit’s fair value up to a maximum amount of the goodwill balance for the reporting unit. We determine fair values for each of the reporting units using the market approach, when available and appropriate, or the income approach, or a combination of both. If multiple valuation methodologies are used, the results are weighted appropriately. Valuations using the market approach are derived from metrics of publicly traded comparable companies. The selections of comparable businesses are based on the markets in which our reporting units operate, giving consideration to risk profiles, size, geography and diversity of products and services. Under the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. We use our internal forecasts to estimate future cash flows and include an estimate of long-term future growth rates based on our most recent views of the long-term outlook for each business. As defined in the authoritative guidance, a reporting unit is an operating segment or one level below an operating segment. During the fourth quarter of 2022, we performed our annual impairment test of goodwill for all our reporting units using a qualitative approach. Based on the results of our qualitative testing, we believe that it is more-likely-than-not that the fair value of each reporting unit is greater than its respective carrying value. There were no impairments of goodwill during the years ended October 31, 2022, 2021 and 2020. See Note 2, “Acquisitions,” and Note 7, “Goodwill and Other Intangible Assets,” for additional information about our goodwill and other intangible assets. Other intangible assets consist primarily of developed technologies, proprietary know-how, trademarks, customer relationships, non-compete agreements, and acquired backlog and are amortized using the straight-line method over estimated useful lives ranging from 6 months to 12 years. We review other intangible assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. No impairments of purchased intangible assets were recorded during the years ended October 31, 2022, 2021 and 2020. The authoritative accounting guidance allows a qualitative approach for testing indefinite-lived intangible assets for impairment, similar to the impairment testing guidance for goodwill. It allows the option to first assess qualitative factors (events and circumstances) that could have affected the significant inputs used in determining the fair value of the indefinite-lived intangible asset. The qualitative factors assist in determining whether it is more-likely-than-not that the indefinite-lived intangible asset is impaired. An organization may choose to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to calculating its fair value. Our indefinite-lived intangible assets are in-process research and development ("IPR&D") intangible assets. In 2022, 2021 and 2020 we assessed impairment by performing a qualitative test and concluded that no material impairment of indefinite-lived intangible assets was required.
Advertising	Advertising costs are expensed as incurred and were $27 million in 2022, $21 million in 2021 and $24 million in 2020.
Research and development	Costs related to the research, design and development of our products are charged to research and development expense as they are incurred.
Investments	Investments with readily determinable fair values and trading securities are reported at fair value. Equity investments without readily determinable fair values are measured at cost with adjustments for observable changes in price or impairments. Gains or losses resulting from changes in fair value are recognized currently in earnings. The company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may not be recoverable. There was no impairment recognized in 2022, 2021 and 2020.
Net income per share	Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period excluding the dilutive effect of stock options and other employee stock plans. Diluted net income per share gives effect to all potentially dilutive common stock equivalents outstanding during the period. The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense, and the dilutive effect of in-the-money options and non-vested RSUs. Under the treasury stock method, the amount the employee must pay for exercising stock options and unamortized share-based compensation expense are assumed proceeds to be used to repurchase hypothetical shares.
Cash, cash equivalents and short term investments	We classify investments as cash equivalents if their original maturity or remaining maturity at the time of purchase is three months or less at the date of purchase. Cash equivalents are stated at cost, which approximates fair value. As of October 31, 2022, approximately $1.7 billion of our cash, cash equivalents and restricted cash was held outside of the U.S. in our foreign subsidiaries. Our cash and cash equivalents mainly consist of investments in institutional money market funds, short-term deposits held at major global financial institutions, and similar short duration instruments with original maturities of three months or less. We continuously monitor the creditworthiness of the financial institutions in which we invest our funds. We utilize a variety of funding strategies in an effort to ensure that our worldwide cash is available in the locations in which it is needed. Most significant international locations have access to internal funding through an offshore cash pool for working capital needs. In addition, a few locations that are unable to access internal funding have access to temporary local overdraft and short-term working capital lines of credit. We classify investments as short-term investments if their original maturities are greater than three months and their remaining maturities are one year or less.
Fair value of financial instruments	The carrying values of certain of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities, approximate fair value because of their short maturities. The fair value of long-term equity investments is determined using quoted market prices for those securities when available. For those long-term equity investments accounted for under the equity method or measurement alternative, the carrying value approximates estimated fair value. The fair value of our long-term debt, calculated from quoted prices that are primarily Level 1 inputs under the accounting guidance fair value hierarchy, is approximately $1,679 million and $1,977 million as of October 31, 2022 and 2021, respectively. The fair value of foreign currency contracts used for hedging purposes is estimated internally by using inputs tied to active markets. These inputs, for example, interest rate yield curves, foreign exchange rates, and forward and spot prices for currencies, are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. See also Note 8, "Fair Value Measurements," for additional information on the fair value of financial instruments.
Concentration of credit risk	Financial instruments that potentially subject us to significant concentration of credit risk include money market fund investments, time deposits and demand deposit balances. These investments are categorized as cash and cash equivalents, short-term investments and long-term investments. In addition, we have credit risk from derivative financial instruments used in hedging activities and accounts receivable. We invest in a variety of financial instruments and limit the amount of credit exposure with any one financial institution. We have a comprehensive credit policy in place and credit exposure is monitored on an ongoing basis. Credit risk with respect to our accounts receivable is diversified due to the large number of entities comprising our customer base and their dispersion across many different industries and geographies. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated through collateral, such as letters of credit, bank guarantees or payment terms like cash in advance. N o single customer accounted for more than 10 percent of accounts receivabl e as of October 31, 2022 or 2021.
Derivative instruments	We are exposed to global foreign currency exchange rate fluctuations in the normal course of business. We enter into foreign exchange hedging contracts, and primarily use forward contracts to manage financial exposures resulting from changes in foreign currency exchange rates. Foreign currency exposures include committed and anticipated revenue and expense transactions (cash flow exposure) and assets and liabilities that are denominated in currencies other than the functional currency of the subsidiary (balance sheet exposure). For cash flow hedges, contracts are designed at inception as hedges of the related foreign currency exposures. We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions at the inception of the hedge. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the hedging instruments are highly effective in offsetting changes in cash flows of hedged items. Our foreign exchange cash flow hedging contracts have maturities based on a rolling period of up to twelve months. We do not use derivative financial instruments for speculative trading purposes. All derivatives are recognized on the balance sheet at their fair values. For derivative instruments that are designated and qualify as a cash flow hedge, changes in the value of the effective portion of the derivative instrument is recognized in accumulated comprehensive income, a component of stockholders' equity. Amounts associated with cash flow hedges are reclassified and recognized in income when either the forecast transaction occurs or it becomes probable the forecast transaction will not occur. Derivatives not designated as hedging instruments are recorded on the balance sheet at fair value, and changes in fair value are recorded in earnings in the current period. Derivative instruments are subject to master netting arrangements and qualify for net presentation in the balance sheet. Cash flows from derivative instruments are classified in the statement of cash flows in the same category as the cash flows from the hedged or economically hedged item, primarily in operating activities.
Property, plant and equipment	Property, plant and equipment are stated at cost less accumulated depreciation. Additions, improvements and major renewals are capitalized; maintenance, repairs and minor renewals are expensed as incurred. When assets are retired or disposed of, the assets and related accumulated depreciation are removed from our general ledger, and the resulting gain or loss is reflected in the consolidated statement of operations. We use the straight-line method to depreciate assets. Buildings and improvements are depreciated over the lesser of their useful lives, which is generally over five years to forty years, or the remaining term of the lease; and machinery and equipment is generally depreciated over three years to ten years.
Leases	We adopted Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC 842”), on November 1, 2019 using the modified retrospective transition approach provided by Accounting Standards Update ("ASU") 2018-11, Leases: Targeted Improvements, with the cumulative effect of initially applying the standard recognized at the date of adoption. We determine whether an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities (current and non-current) on our consolidated balance sheet. Finance leases are included in property, plant and equipment, other accrued liabilities, and other long-term liabilities in our consolidated balance sheet. Our finance lease and lessor arrangements are immaterial. ROU assets and lease obligations are recognized based on their present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the lease term and economic environment to discount lease obligations. ROU assets also include any lease payments made and exclude lease incentives and initial direct costs incurred. We initially measure payments based on an index by using the applicable rate at lease commencement. Variable payments that do not depend on an index are not included in the lease liability and are recognized as they are incurred. See Note 10, "Leases," for additional information.
Impairment of long-lived assets	We continually monitor events and changes in circumstances that could indicate carrying amounts of long-lived assets may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the undiscounted future cash flows is less than the carrying amount of those assets, we recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets.
Restructuring costs	The main component of our existing restructuring plans is related to workforce reductions and site restructuring. Workforce reduction charges are accrued when payment of benefits becomes probable and the amounts can be estimated. If the amounts and timing of cash flows from restructuring activities are significantly different from what we have estimated, the actual amount of restructuring and other related charges could be materially different, either higher or lower, than those we have recorded.
Employee compensation and benefits	Amounts owed to employees, such as accrued salary, bonuses and vacation benefits are reported within employee compensation and benefits in the consolidated balance sheet. The total amount of accrued vacation benefit was $109 million and $114 million as of October 31, 2022 and 2021, respectively.
Foreign currency translation	We translate and remeasure balance sheet and statement of operations items into U.S. dollars. For those subsidiaries that operate in a local currency functional environment, all assets and liabilities are translated into U.S. dollars using current exchange rates at the balance sheet date; revenue and expenses are translated using monthly exchange rates that approximate average exchange rates in effect during each period. Resulting translation adjustments are reported as a separate component of accumulated other comprehensive income (loss) in stockholders' equity.For those subsidiaries that operate in a U.S. dollar functional environment, foreign currency assets and liabilities are re-measured into U.S. dollars at current exchange rates except for non-monetary assets and capital accounts, which are remeasured at historical exchange rates. Revenue and expenses are generally remeasured at monthly exchange rates that approximate average exchange rates in effect during each period. Gains or losses from foreign currency re-measurement are included in net income. Net gains or losses resulting from foreign currency asset and liability remeasurement transactions are reported in other income (expense) and were a $1 million loss in 2022, a $3 million gain in 2021 and a $3 million gain in 2020.
Retirement plans and post-retirement benefit plan assumptions	Defined benefit plan obligations are remeasured at least annually as of October 31, based on the present value of future benefit payments to reflect future benefit costs over the employees' average expected future service to Keysight based on the terms of the plans. To estimate the present value of these future payments, we are required to make assumptions using actuarial concepts within the framework of GAAP. Two critical assumptions are the discount rate and the expected long-term return on plan assets. Other important assumptions include expected future salary increases, expected future increases to benefit payments, expected retirement dates, employee turnover, retiree mortality rates and investment portfolio composition. We evaluate these assumptions at least annually. See Note 12, "Retirement Plans and Post-Retirement Benefit Plans."

Unrecorded Unconditional Purchase Obligation, Description	Commitments to contract manufacturers and suppliers. We purchase components from a variety of suppliers and use several contract manufacturers to provide manufacturing services for our products. During the normal course of business, we issue purchase orders with estimates of our requirements several months ahead of the delivery dates. The reported open purchase orders represent a commitment to our suppliers. Our agreements with suppliers for common materials provide us with the option to cancel, reschedule, and adjust our requirements based on business needs. We expect to fulfill most of our purchase commitments for inventory within one year or based on mutually agreed terms.
