Accounting Policies [Abstract]
OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	50% chance) 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. Due to cancellation of a specific IPR&D project, we recorded an impairment of $1 million in 2013. There were no impairments in fiscal years 2015 and 2014. In all other instances we used the qualitative test and concluded that it was more-likely-than-not that all other indefinite-lived assets were not impaired. Advertising. Advertising costs are expensed as incurred and amounted to $27 million in 2015 , $22 million in 2014 and $16 million in 2013 . 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. Sales taxes. Sales taxes collected from customers and remitted to governmental authorities are not included in our revenue. Investments. Cost method investments consisting of non-marketable equity securities are accounted for at historical cost. Trading securities are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. Investments designated as available-for-sale are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income. The Company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may not be recoverable. In 2015, cost method investments with a carrying amount of $4 million were written down to their fair value of zero , resulting in an impairment charge of $4 million , which is included in other income (expense), net. There were no impairments recognized in 2014 and 2013. Net income per share. Basic net income per share is computed by dividing net income - the numerator - by the weighted average number of common shares outstanding - the denominator - 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, the tax benefits and shortfalls charged to additional paid-in capital and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options, unamortized share-based compensation expense and tax benefits or shortfalls are assumed proceeds to be used to repurchase hypothetical shares. Basic and diluted net income per share for all periods through October 31, 2014 is calculated using the shares distributed on November 1, 2014. See Note 7, "Net Income Per Share." 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, 2015 , approximately $338 million of our cash and cash equivalents was held outside of the U.S. in our foreign subsidiaries. Under current tax laws, most of the cash could be repatriated to the U.S., but it would be subject to U.S. federal and state income taxes, less applicable foreign tax credits. Our cash and cash equivalents mainly consist of short-term deposits held at major global financial institutions, investments in institutional money market funds, and similar short duration instruments with original maturities of 90 days or less. We continuously monitor the creditworthiness of the financial institutions and institutional money market funds in which we invest our funds. 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 cost or equity method, their carrying value approximates their estimated fair value. The fair value of our long-term debt, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy, was below the carrying value by approximately $8 million as of October 31, 2015 and exceeded the carrying value by approximately $1 million as of October 31, 2014. 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 13, "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 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. Credit evaluation is performed by an independent team to ensure proper segregation of duties. No single customer accounted for more than 10 percent of accounts receivable as of October 31, 2015 or 2014 . Derivative instruments. We are exposed to global foreign currency exchange rate risk in the normal course of business. We enter into foreign exchange hedging contracts, primarily forward contracts and purchased options 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. For option contracts, we exclude time value from the measurement of effectiveness. 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 hedging contracts generally mature within twelve months. In order to manage foreign currency exposures in a few limited jurisdictions we may enter into foreign exchange contracts that do not qualify for hedge accounting. In such circumstances, the local foreign currency exposure is offset by contracts owned by the parent company. 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 their fair value and changes in the fair values are recorded in the income statement in the current period. Derivative instruments are subject to master netting arrangements and qualify for net presentation in the balance sheet. Changes in the fair value of the ineffective portion of derivative instruments are recognized in earnings in the current period. 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 and amortization are removed from our general ledger, and the resulting gain or loss is reflected in the combined and consolidated statement of operations. Buildings and improvements are depreciated over the lesser of their useful lives or the remaining term of the lease and machinery and equipment over three to ten years. We use the straight-line method to depreciate assets. Leases. We lease buildings, machinery and equipment under operating leases for original terms ranging generally from one to twenty-five years. Certain leases contain renewal options for periods up to ten years. Capitalized software. We capitalize certain internal and external costs incurred to acquire or create internal use software. Capitalized software is included in property, plant and equipment and is depreciated over three to five years once development is complete. Impairment of long-lived assets. We continually monitor events and changes in circumstances that could indicate carrying amounts of long-lived assets, including intangible 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" id="sjs-B4">OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Overview. Keysight Technologies, Inc. ("we", "us", "Keysight" or the "company"), incorporated in Delaware on December 6, 2013, is a measurement company providing core electronic design and test solutions to communications and electronics industries. Separation from Agilent. On November 1, 2014, Keysight became an independent publicly-traded company through the distribution by Agilent Technologies Inc. ("Agilent") of 100 percent of the outstanding common stock of Keysight to Agilent's shareholders (the "Separation"). Each Agilent shareholder of record as of the close of business on October 22, 2014 received one share of Keysight common stock for every two shares of Agilent common stock held on the record date. Approximately 167 million shares of Keysight common stock were distributed on November 1, 2014 to Agilent shareholders. Keysight's Registration Statement on Form 10 was declared effective by the U.S. Securities and Exchange Commission ("SEC") on October 6, 2014. Keysight's common stock began trading "regular-way" under the ticker symbol "KEYS" on the New York Stock Exchange on November 3, 2014. Acquisition of Anite . On August 13, 2015 , we acquired all share capital of Anite plc ("Anite") for a cash price of approximately $558 million , net of $43 million of cash acquired. Anite is a U.K.-based global company and a leading supplier of wireless test solutions with strong software expertise. This acquisition expands our solutions offering in wireless research and development design and test. Coupled with Keysight's expertise in helping customers design and test hardware, we can now provide customers with comprehensive wireless solutions. Anite also has a Network Test business that brings innovative solutions that help deliver an outstanding experience for mobile users in the network. Anite results are included in Keysight's consolidated financial statements from the date of acquisition and are reported in the measurement solutions segment. For additional details related to the acquisition of Anite, see Note 3, "Acquisitions." Basis of presentation. We have prepared the accompanying financial statements pursuant to the rules and regulations of the SEC and in conformity with U.S. generally accepted accounting principles ("GAAP"). Our fiscal year end is October 31. Unless otherwise stated, all years and dates refer to our fiscal year. Agilent transferred substantially all of the assets and liabilities and operations of the electronic measurement business to Keysight in August 2014 ("the Capitalization"). Combined financial statements prior to the Capitalization were prepared on a stand-alone basis and were derived from Agilent’s consolidated financial statements and accounting records. Expenses were allocated to us using estimates that we consider to be a reasonable reflection of the utilization of services provided or the benefit received by us during the periods presented. Following the Capitalization, the consolidated financial statements include the accounts of the company and our wholly-owned subsidiaries. For the first half of fiscal 2015, Agilent provided some services on a transitional basis for a fee, which were partially offset by other income from Keysight services provided to Agilent. These services were received or provided under a transition services agreement. The net costs associated with the transition services agreement were not materially different than the historical costs that were allocated to us related to these same services. Management is responsible for the fair presentation of the accompanying combined and consolidated financial statements, prepared in accordance with U.S. GAAP, and has full responsibility for their integrity and accuracy. In the opinion of management, the accompanying combined and consolidated financial statements contain all adjustments necessary to present fairly our consolidated balance sheet and our combined and consolidated statement of operations, statement of comprehensive income, statement of cash flows and statement of equity for all periods presented. Principles of consolidation. The combined and consolidated financial statements include the accounts of the company and our wholly- and majority-owned subsidiaries. All significant inter-company transactions have been eliminated. All significant transactions between us and other businesses of Agilent are included in these combined and consolidated financial statements. All inter-company transactions prior to the Capitalization are considered to be effectively settled for cash in the combined and consolidated statement of cash flows at the time the transaction is recorded. Use of estimates. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our combined and 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 best knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. 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, allocation methods and allocated expenses from Agilent prior to the separation, valuation of goodwill and other intangible assets, share-based compensation, retirement and post-retirement plan assumptions, restructuring, warranty and accounting for income taxes. Revenue recognition. We enter into agreements to sell products (hardware and/or software), services and other arrangements (multiple-element arrangements) that include combinations of products and services. We recognize revenue, net of trade discounts and allowances, provided that (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) the price is fixed or determinable and (4) collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer, for products, or when the service has been provided. We consider the price to be fixed or determinable when the price is not subject to refund or adjustments. We consider arrangements with extended payment terms not to be fixed or determinable, and accordingly we defer revenue until amounts become due. At the time of the transaction, we evaluate the creditworthiness of our customers to determine the appropriate timing of revenue recognition. Product revenue. Our product revenue is generated predominantly from the sales of various types of test equipment and associated software. Product revenue, including sales to resellers and distributors, is reduced for estimated returns, when appropriate. For sales or arrangements that include customer-specified acceptance criteria, including those where acceptance is required upon achievement of performance milestones, revenue is recognized after the acceptance criteria have been met. For products that include installation, if the installation meets the criteria to be considered a separate element, product revenue is recognized upon delivery, and recognition of installation revenue is delayed until the installation is complete. Otherwise, neither the product nor the installation revenue is recognized until the installation is complete. Where software is licensed separately, revenue is recognized when the software is delivered and has been transferred to the customer or, in the case of electronic delivery of software, when the customer is given access to the licensed software programs. We also evaluate whether collection of the receivable is probable, the fee is fixed or determinable and whether any other undelivered elements of the arrangement exist on which a portion of the total fee would be allocated based on vendor-specific objective evidence ("VSOE"). When VSOE is not available we then use third-party evidence ("TPE") or management's best estimate of selling price ("ESP"). Service revenue. Revenue from services includes repair and calibration services, extended warranty, customer and software support, consulting, training and education. Service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer. For example, customer support contracts are recognized rateably over the contractual period, while training revenue is recognized as the training is provided to the customer. In addition, the four revenue recognition criteria described above must be met before service revenue is recognized. Revenue recognition for arrangements with multiple deliverables. Our multiple-element arrangements are generally comprised of a combination of measurement instruments, installation or other start-up services, and/or software and/or support or services. Hardware and software elements are typically delivered at the same time and revenue is recognized upon delivery and acceptance, if required, once title and risk of loss pass to the customer. Delivery of installation, start-up services and other services varies based on the complexity of the equipment, staffing levels in a geographic location and customer preferences, and can range from a few days to a few months. Service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer. Revenue from the sale of software products that are not required to deliver the tangible product's essential functionality are accounted for under software revenue recognition rules which require VSOE of fair value to allocate revenue in a multiple-element arrangement. Our arrangements generally do not include any provisions for cancellation, termination, or refunds that would significantly impact recognized revenue. We evaluate the deliverables in our multiple-element arrangements and conclude that they are separate units of accounting if it is determined the delivered item or items have value to the customer on a standalone basis. For arrangements that include a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) has been determined to be probable and substantially in our control. We allocate revenue to each element in our multiple-element arrangements based upon their relative selling prices. We determine the selling price for each deliverable based on a selling price hierarchy. The selling price for a deliverable is based on VSOE if available, TPE if VSOE is not available, or ESP if neither VSOE nor TPE is available. Revenue allocated to each element is then recognized when the basic revenue recognition criteria for that element have been met. We use VSOE of selling price in the selling price allocation in all instances where it exists. VSOE of selling price for products and services is determined when a substantial majority of the selling prices fall within a reasonable range when sold separately. TPE of selling price can be established by evaluating largely interchangeable competitor products or services in standalone sales to similarly situated customers. As our products contain a significant element of proprietary technology and the solution offered differs substantially from that of competitors, it is difficult to obtain the reliable standalone competitive pricing necessary to establish TPE. ESP represents the best estimate of the price at which we would transact a sale if the product or service were sold on a standalone basis. We determine ESP for a product or service by using historical selling prices which reflect multiple factors including, but not limited to, customer type, geography, market conditions, competitive landscape, gross margin objectives and pricing practices. The determination of ESP is made through consultation with and approval by management. We may modify or develop new pricing practices and strategies in the future. As these pricing strategies evolve, changes may occur in ESP. The aforementioned factors may result in a different allocation of revenue to the deliverables in multiple-element arrangements, which may change the pattern and timing of revenue recognition for these elements but will not change the total revenue recognized for the arrangement. Shipping and handling costs. Our shipping and handling costs charged to customers are included in net revenue, and the associated expense is recorded in cost of products for all periods presented. Deferred revenue. Deferred revenue represents the amount that is allocated to undelivered elements in multiple-element arrangements. We limit the revenue recognized to the amount that is not contingent on the future delivery of products or services or meeting other specified performance conditions. In addition, service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer. 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 doubtful accounts, 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 doubtful accounts as of October 31, 2015 and 2014 was not material. We do not have any off-balance-sheet credit exposure related to our customers. Accounts receivable are also recorded net of product returns. Share-based compensation. Prior to our separation from Agilent, our employees historically participated in Agilent’s various incentive award plans, including employee stock options, restricted stock units and the employee stock purchases made under Agilent’s Employee Stock Purchase Plan ("Agilent's ESPP”) and we participated in Agilent’s share-based compensation plans and recorded share-based compensation expense based on the equity awards granted to our employees. We recorded compensation expense based on expenses for the awards to our employees as well as an allocation of Agilent’s corporate and shared services employee expenses. In 2015 , we accounted for share-based awards made to our employees and directors including employee stock option awards, restricted stock units, employee stock purchases made under Keysight's Employee Stock Purchase Plan ("Keysight's ESPP") and performance share awards under Keysight Technologies, Inc. Long-Term Performance ("Keysight's LTP") Program using the estimated grant date fair value method of accounting. In 2014 and 2013 , we accounted for share-based awards made to our employees and directors including employee stock option awards, restricted stock units, employee stock purchases made under Agilent's ESPP and performance share awards under Agilent Technologies, Inc. Long-Term Performance ("Agilent's LTP") Program using the estimated grant date fair value method of accounting. Under the fair value method, we recorded compensation expense for all share-based awards of $55 million in 2015 , $44 million in 2014 and $43 million in 2013 . 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. Our standard warranty term for most of our products from the date of delivery is typically three years, which increased from one year in the second quarter of fiscal 2013. We accrue for standard warranty costs based on historical trends in warranty charges as a percentage of net product revenue. 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 17, "Guarantees." 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. 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 recognizing and measuring 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% 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 at least annually in the fourth quarter, as of September 30, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. In accordance with the authoritative accounting guidance we have the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If we determine this is the case, we are required to perform the two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized. If we determine that it is more-likely-than-not that the fair value of the reporting unit is greater than its carrying amounts, the two-step goodwill impairment test is not required. As defined in the authoritative guidance, a reporting unit is an operating segment, or one level below an operating segment. Historically, we conducted our business in a single operating segment and reporting unit. In fiscal 2014, in conjunction with the planned separation, we implemented changes in our organizational structure which resulted in the formation of two reportable operating segments, which are also our reporting units. In fiscal year 2015, we assessed goodwill impairment by performing a qualitative test for our two reporting units, which consisted of our two segments, Measurement Solutions and Customer Support and Services. Based on the results of our testing, it was determined that it is more-likely-than-not that the fair value of the reporting units are greater than their carrying amounts. There was no impairment of goodwill during the years ended October 31, 2015, 2014 and 2013. Other intangible assets consist primarily of developed technologies, proprietary know-how, trademarks, and customer relationships and are amortized using the straight-line method over estimated useful lives ranging from 6 months to 15 years. No impairments of purchased intangible assets were recorded during the year ended October 31, 2015, 2014 and 2013. 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. 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 (i.e. > 50% chance) 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. Due to cancellation of a specific IPR&D project, we recorded an impairment of $1 million in 2013. There were no impairments in fiscal years 2015 and 2014. In all other instances we used the qualitative test and concluded that it was more-likely-than-not that all other indefinite-lived assets were not impaired. Advertising. Advertising costs are expensed as incurred and amounted to $27 million in 2015 , $22 million in 2014 and $16 million in 2013 . 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. Sales taxes. Sales taxes collected from customers and remitted to governmental authorities are not included in our revenue. Investments. Cost method investments consisting of non-marketable equity securities are accounted for at historical cost. Trading securities are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. Investments designated as available-for-sale are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income. The Company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may not be recoverable. In 2015, cost method investments with a carrying amount of $4 million were written down to their fair value of zero , resulting in an impairment charge of $4 million , which is included in other income (expense), net. There were no impairments recognized in 2014 and 2013. Net income per share. Basic net income per share is computed by dividing net income - the numerator - by the weighted average number of common shares outstanding - the denominator - 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, the tax benefits and shortfalls charged to additional paid-in capital and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options, unamortized share-based compensation expense and tax benefits or shortfalls are assumed proceeds to be used to repurchase hypothetical shares. Basic and diluted net income per share for all periods through October 31, 2014 is calculated using the shares distributed on November 1, 2014. See Note 7, "Net Income Per Share." 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, 2015 , approximately $338 million of our cash and cash equivalents was held outside of the U.S. in our foreign subsidiaries. Under current tax laws, most of the cash could be repatriated to the U.S., but it would be subject to U.S. federal and state income taxes, less applicable foreign tax credits. Our cash and cash equivalents mainly consist of short-term deposits held at major global financial institutions, investments in institutional money market funds, and similar short duration instruments with original maturities of 90 days or less. We continuously monitor the creditworthiness of the financial institutions and institutional money market funds in which we invest our funds. 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 cost or equity method, their carrying value approximates their estimated fair value. The fair value of our long-term debt, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy, was below the carrying value by approximately $8 million as of October 31, 2015 and exceeded the carrying value by approximately $1 million as of October 31, 2014. 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 13, "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 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. Credit evaluation is performed by an independent team to ensure proper segregation of duties. No single customer accounted for more than 10 percent of accounts receivable as of October 31, 2015 or 2014 . Derivative instruments. We are exposed to global foreign currency exchange rate risk in the normal course of business. We enter into foreign exchange hedging contracts, primarily forward contracts and purchased options 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. For option contracts, we exclude time value from the measurement of effectiveness. 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 hedging contracts generally mature within twelve months. In order to manage foreign currency exposures in a few limited jurisdictions we may enter into foreign exchange contracts that do not qualify for hedge accounting. In such circumstances, the local foreign currency exposure is offset by contracts owned by the parent company. 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 their fair value and changes in the fair values are recorded in the income statement in the current period. Derivative instruments are subject to master netting arrangements and qualify for net presentation in the balance sheet. Changes in the fair value of the ineffective portion of derivative instruments are recognized in earnings in the current period. 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 and amortization are removed from our general ledger, and the resulting gain or loss is reflected in the combined and consolidated statement of operations. Buildings and improvements are depreciated over the lesser of their useful lives or the remaining term of the lease and machinery and equipment over three to ten years. We use the straight-line method to depreciate assets. Leases. We lease buildings, machinery and equipment under operating leases for original terms ranging generally from one to twenty-five years. Certain leases contain renewal options for periods up to ten years. Capitalized software. We capitalize certain internal and external costs incurred to acquire or create internal use software. Capitalized software is included in property, plant and equipment and is depreciated over three to five years once development is complete. Impairment of long-lived assets. We continually monitor events and changes in circumstances that could indicate carrying amounts of long-lived assets, including intangible 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

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	NEW ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board ("FASB") issued an amendment to the accounting guidance related to revenue recognition. The amendment was the result of a joint project between the FASB and the International Accounting Standards Board ("IASB") to clarify the principles for recognizing revenue and to develop common revenue standards for U.S. GAAP and International Financial Reporting Standards ("IFRS"). To meet those objectives, the FASB amended the FASB Accounting Standards Codification and creating a new Topic 606, Revenue from Contracts with Customers, and the IASB is issuing IFRS 15, Revenue from Contracts with Customers. On July 9, 2015, the FASB deferred the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date. The FASB also permitted early adoption of the standard, but not before the original effective date of December 15, 2016. We are evaluating the impact of adopting this guidance to our combined and consolidated financial statements. In June 2014, the FASB issued an amendment to the accounting guidance relating to share-based compensation to resolve what it saw as diverse accounting treatment of certain awards. With this amendment, the FASB has given explicit guidance to treat a performance target that could be achieved after the requisite service period as a performance condition that affects vesting rather than as a non-vesting condition that affects the grant-date fair value of an award. The new guidance is effective for annual periods beginning after December 15, 2015 and for the interim periods within those annual periods. Earlier adoption is permitted. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In August 2014, the FASB issued guidance related to the disclosures around going concern. The standard provided guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The standard is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In February 2015, the FASB issued guidance with respect to the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The new guidance affects the following areas: (1) limited partnerships and similar legal entities, (2) evaluating fees paid to a decision maker or a service provider as a variable interest, (3) the effect of fee arrangements on the primary beneficiary determination, (4) the effect of related parties on the primary beneficiary determination, and (5) certain investment funds. The new guidance is effective for annual periods beginning after December 15, 2015, and interim periods within those annual periods. Early adoption is permitted. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In April 2015, the FASB issued guidance to simplify presentation of debt issuance costs. The standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The standard is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In April 2015, the FASB issued guidance that clarifies the circumstances under which a cloud computing customer would account for an arrangement as a license of internal-use software. The standard is effective for annual periods beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In May 2015, the FASB issued guidance that removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The standard also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The standard is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. Early adoption is permitted. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In July 2015, the FASB issued guidance to simplify the subsequent measurement of inventory. The standard requires most inventory to be measured at the lower of cost and net realizable value, thereby simplifying the current guidance under which inventory must be measured at the lower of cost or market (where market was defined as replacement cost, with a ceiling of net realizable value and floor of net realizable value less a normal profit margin). The standard is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early application is permitted. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In August 2015, the FASB issued guidance to simplify presentation of debt issuance costs associated with line of credit arrangements. The standard clarifies the SEC's position on presenting and measuring debt issuance costs incurred in connection with line of credit arrangements as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line of credit arrangement. The standard is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In September 2015, the FASB issued guidance that requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Under the standard, if the initial accounting for a business combination is incomplete at the end of the reporting period in which the combination occurs, the acquirer would no longer be required to revise its comparative information for changes to the provisional amounts recognized as of the acquisition date during the measurement period. The standard is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. We adopted this guidance in the fourth quarter of 2015. We do not expect a material impact to our combined and consolidated financial statements due to the adoption of this guidance. In November 2015, the FASB issued guidance that requires deferred income tax liabilities and assets to be classified as noncurrent. The standard is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. We are still in the process of evaluating the effect of adoption on our financial statements. Other amendments to GAAP in the U.S. that have been issued by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on our combined and consolidated financial statements upon adoption.

ACQUISITION OF ANITE

ACQUISITION OF ANITE	12 Months Ended
	Oct. 31, 2015
Business Combinations [Abstract]
ACQUISITION OF ANITE	ACQUISITION OF ANITE On August 13, 2015 , we acquired all share capital of Anite. Anite is a U.K.-based global company with strong software expertise and a leading supplier of wireless test solutions. As a result of the acquisition, Anite has become a wholly-owned subsidiary of Keysight. Accordingly, the results of Anite are included in Keysight's consolidated financial statements from the date of the acquisition. For the period from August 14, 2015 to October 31, 2015, Anite's net revenue was $25 million and net loss was $14 million . This acquisition strengthens our wireless software design and test portfolio and its Network Test business expands our served addressable market. Coupled with Keysight's expertise in helping customers design and test hardware, we can now provide customers with more comprehensive wireless solutions. Anite’s Network Test business will also enable us to provide innovative solutions that help customers deliver an outstanding experience for mobile users in the network. The consideration paid was approximately $558 million , net of $43 million of cash acquired. We funded the acquisition using our existing cash. In connection with the acquisition of Anite, we entered into several foreign currency forward contracts to mitigate the currency exchange risk associated with the payment of the purchase price in British Pound ("GBP") currency. The aggregate notional amount of the currencies hedged was $608 million . These foreign exchange contracts did not qualify for hedge accounting treatment and were not designated as hedging instruments. The resulting loss on settlement, on the date of acquisition, was $2 million and was recorded in other income (expense), net in the consolidated statement of operations for the year ended October 31, 2015. The Anite acquisition was accounted for in accordance with the authoritative accounting guidance. The acquired assets and assumed liabilities were recorded by Keysight at their estimated fair values. Keysight determined the estimated fair values with the assistance of appraisals or valuations performed by third party specialists, discounted cash flow analysis, and estimates made by management. We expect to leverage and expand the existing sales channels and product development resources, and utilize the assembled workforce. The company also anticipates opportunities for growth through expanded geographic and customer segment diversity and the ability to leverage additional products and capabilities. These factors, among others, contributed to a purchase price in excess of the estimated fair value of Anite's net identifiable assets acquired (see summary of net assets below), and, as a result, we have recorded goodwill in connection with this transaction. All goodwill was allocated to the measurement solutions reporting unit. We do not expect the goodwill recognized to be deductible for income tax purposes. Any impairment charges made in the future associated with goodwill will not be tax deductible. A portion of the overall purchase price was allocated to acquired intangible assets. Amortization expense associated with acquired intangible assets is not deductible for tax purposes. Therefore, a deferred tax liability of approximately $47 million was established primarily for the future amortization of these intangibles and is included in "other long-term liabilities" in the table below. The following table summarizes the preliminary allocation of the purchase price to the estimated fair values of the assets acquired and liabilities assumed on the closing date of August 13, 2015 (in millions): Cash and cash equivalents $ 43 Accounts receivable 32 Inventory 19 Deferred tax assets 1 Other current assets 10 Property, plant and equipment 34 Intangible assets 244 Goodwill 317 Long-term deferred tax assets 4 Total assets acquired 704 Accounts payable (10 ) Employee compensation and benefits (3 ) Deferred revenue (17 ) Income and other taxes payable (1 ) Other accrued liabilities (20 ) Other long-term liabilities (50 ) Net assets acquired $ 603 The fair value of cash and cash equivalents, accounts receivable, other current assets, accounts payable, employee compensation and benefits, and other accrued liabilities were generally determined using historical carrying values given the short-term nature of these assets and liabilities. The fair values for acquired inventory, property, plant and equipment, intangible assets, and deferred revenue were determined with the input from third-party valuation specialists. The fair values of certain other assets and certain other liabilities were determined internally using historical carrying values and estimates made by management. As additional information becomes available, we may revise the preliminary purchase price allocation during the remainder of the measurement period (which will not exceed 12 months from the acquisition date). Any such revisions or changes may be material. Valuations of intangible assets acquired The components of intangible assets acquired in connection with the Anite acquisition were as follows (in millions): Estimated Fair Value Estimated useful life Developed product technology $ 182 6 years Customer relationships 31 8 years Tradenames and trademarks 19 10 years Total intangible assets subject to amortization 232 In-process research and development 12 Total intangible assets $ 244 As noted above, the intangible assets were valued with input from valuation specialists using the income approach, which includes the discounted cash flow, cost-savings, and relief from royalty methods. The in-process research and development was valued using the multi-period excess earnings method under the income approach by discounting forecasted cash flows directly related to the products expecting to result from the projects, net of returns on contributory assets. Discount rates of 11% and 11.5% were used to value the research and development projects, adjusted to reflect additional risks inherent in the acquired projects. The primary in-process projects acquired relate to next generation products which will be released in the near future. Total costs to complete for all Anite in-process research and development were estimated at approximately $1 million as of the close date. Acquisition and integration costs directly related to the Anite acquisition totaled $14 million for the year ended October 31, 2015 and were recorded in selling, general and administrative expenses. Such costs are expensed in accordance with the authoritative accounting guidance. The following represents pro forma operating results as if Anite had been included in the company's combined and consolidated statements of operations as of the beginning of fiscal 2014 (in millions, except per share amounts): 2015 2014 Net revenue $ 2,998 $ 3,096 Net income $ 510 $ 422 Net income per share - Basic $ 3.02 $ 2.53 Net income per share - Diluted $ 2.98 $ 2.53 The pro forma financial information assumes that the companies were combined as of November 1, 2013 and include business combination accounting effects from the acquisition including amortization charges from acquired intangible assets, the impact on cost of sales due to the respective estimated fair value adjustments to inventory, and acquisition-related transaction costs and tax-related effects.

Related Party Transactions [Abstract]
TRANSACTIONS WITH AGILENT	TRANSACTIONS WITH AGILENT Prior to the separation, we were the Electronic Measurement segment of Agilent. After the Capitalization and prior to November 1, 2014, our transactions with Agilent were considered related-party transactions since Agilent owned 100% of our outstanding common stock. The amount of materials and services sold by us to other Agilent businesses was immaterial for the years ended October 31, 2015, 2014 and 2013 and we did not purchase any materials from the other Agilent businesses for those respective periods. Allocated Costs The combined and consolidated statement of operations includes our direct expenses for cost of products and services sold, research and development, sales and marketing, distribution, and administration as well as allocations of expenses arising from shared services and infrastructure provided by Agilent to us. Prior to Separation, these allocated expenses include costs of information technology, accounting and legal services, real estate and facilities, corporate advertising, insurance services, treasury and other corporate and infrastructure services and costs for central research and development efforts. In addition, other costs allocated to us include restructuring costs, share-based compensation expense and retirement plan expenses related to Agilent’s corporate and shared services employees and are included in the table below. These expenses are allocated to us using estimates that we consider to be a reasonable reflection of the utilization of services provided to or benefits received by us. These costs have been allocated to us on the basis of direct usage when identifiable, with the remainder allocated on a pro-rata basis of revenue, square footage, headcount or other measures. Allocated costs included in the accompanying combined statement of operations are as follows: Years ended October 31, 2015 2014 2013 Cost of products and services $ — $ 96 $ 93 Research and development — 44 54 Selling, general and administrative — 273 257 Other (income) expense — (4 ) (4 ) Total allocated costs $ — $ 409 $ 400 Fiscal 2014 includes allocated costs related to the period prior to the Capitalization. Receivable from and Payable to Agilent October 31, 2015 2014 Receivable from Agilent $ — $ 23 Payable to Agilent $ — $ 125 The payable to Agilent was reduced by $25 million during the first quarter of fiscal 2015 as a result of finalization of discussions with Agilent as provided in the separation and distribution agreement. This adjustment was reflected as an increase in additional paid-in-capital in the condensed consolidated balance sheet. The remaining receivables from and payables to Agilent were settled as of October 31, 2015.

SHARE-BASED COMPENSATION

Share-based Compensation [Abstract]
SHARE-BASED COMPENSATION	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 employee stock option awards, Restricted Stock Units ("RSUs"), employee stock purchases made under our Employee Stock Purchase Plan (“ESPP”) and performance share awards granted to selected members of our senior management under the Long-Term Performance (“LTP”) Program based on estimated fair values. Prior to the Separation, Keysight employees participated in Agilent’s equity plans. Upon the Separation, outstanding Keysight employee stock options, RSUs and LTP Program awards previously issued under Agilent’s equity plans were adjusted and converted into new Keysight stock-based awards under the Keysight 2014 Equity and Incentive Compensation Plan using a formula designed to preserve the intrinsic value and fair value of the awards immediately prior to the Separation. These adjusted awards retained the vesting schedule and expiration date of the original awards. 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 the Board of Directors ("the Board") on July 16, 2014, subsequently amended and restated by the Board on September 29, 2014 and on January 22, 2015 and became effective as of November 1, 2014 (the “Effective Date”). The Board 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 provides for the grant of awards in the form of stock options, SARs, 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, 2015, approximately 8 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 and generally have 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. Effective November 1, 2014, the Compensation Committee of the Board of Directors approved the Performance awards plan, which is a performance stock award program 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 period, if specified performance targets are met. Performance awards are generally designed to meet the criteria of a performance award with the performance metrics and peer group comparison set at the beginning of the performance period. Based on the performance metrics the final award may vary from zero to 200 percent of the target award. The maximum contractual term for awards under the Performance awards program is three years . We consider the dilutive impact of this program in our diluted net income per share calculation only to the extent that the performance conditions are met. Restricted stock units 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. Restricted stock units generally vest, with some exceptions, at a rate of 25 percent per year over a period of four years from the date of grant. Effective November 1, 2014, the company adopted the employee stock purchase plan. The ESPP allows eligible employees to contribute up to ten percent of their base compensation to purchase shares of Keysight common stock at 85 percent of the closing market price at 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 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 493,289 shares for $14 million in 2015. As of October 31, 2015, the number of shares of common stock authorized and available for issuance under our ESPP was 24,506,711 . The number of securities remaining available for future issuance is before the issuance of shares of common stock to participants in consideration of the aggregate participant contribution totaling $15 million as of October 31, 2015. Under Agilent's ESPP, our employees purchased 878,816 shares of Agilent for $40 million in 2014 and 764,113 shares of Agilent for $25 million in 2013. The shares purchased by our employees in 2014 include the shares purchased for the second half of 2014 ESPP purchase period. These shares were purchased one month in advance on October 1, 2014, due to separation activities. Impact of Share-based Compensation Awards All share-based awards compensation expense has been recognized using a straight-line amortization method and as required by guidance, has been reduced for estimated forfeitures. The impact on our results for share-based compensation was as follows: Years Ended October 31, 2015 2014 2013 (in millions) Cost of products and services $ 12 $ 11 $ 9 Research and development 9 7 7 Selling, general and administrative 34 26 27 Total share-based compensation expense $ 55 $ 44 $ 43 At October 31, 2015 and 2014 there was no share-based compensation capitalized within inventory. The income tax benefit realized from the exercised stock options and similar awards recognized was $4 million in 2015 , $4 million in 2014 and zero in 2013 . The weighted average grant date fair value of options, granted in 2015 , 2014 and 2013 was $9.20 , $18.73 and $12.18 per share, respectively. Valuation Assumptions The following assumptions were used to estimate the fair value of employee stock options and LTP Program grants. Years Ended October 31, 2015 2014 2013 Stock Option Plans: Weighted average risk-free interest rate 1.60% 1.69% 0.86% Dividend yield 0% 1% 1% Weighted average volatility 31% 39% 39% Expected life 4.9 years 5.8 years 5.8 years LTP Program: Volatility of Keysight shares (Agilent shares for FY13) 26% — 37% Volatility of selected peer-company shares 17%-67% — 6%-64% Price-wise correlation with selected peers 38% — 49% The fair value of share-based awards for employee stock option awards was estimated using the Black-Scholes option pricing model. Shares granted under the LTP Program were valued using a Monte Carlo simulation model. Both the Black-Scholes and Monte Carlo simulation fair value models require the use of highly subjective and complex assumptions, including the option’s expected life and the price volatility of the underlying stock. The estimated fair value of restricted stock awards is determined based on the market price of Keysight’s common stock on the date of grant. Prior to the Separation, it was determined based on the market price of Agilent’s common stock on the date of grant, adjusted for expected dividend yield. For the year ended October 31, 2015, we used the average historical volatility of eleven peer companies to estimate the volatility for our stock option awards. We considered our ability to find traded options of peer companies in the current market with similar terms and prices to our options. For the year ended October 31, 2014 and 2013, we used the historical volatility of Agilent stock to estimate the volatility for stock option awards. In estimating the expected life of our options, we considered the historical option exercise behavior of our executives, which we believe is representative of future behavior. As of November 1, 2014, Agilent’s fiscal 2013 LTP Program grants to Keysight executives are classified as liability awards in our combined and consolidated financial statements as the payout of Keysight shares is dependent upon Agilent Total Shareholder Return (“TSR”) as compared to its peer companies at the end of fiscal 2015. The final payout resulted in reversal of $4 million of expense recorded for those awards. Share-based Payment Award Activity Employee Stock Options The following table summarizes employee stock option award activity made to our employees and directors for 2015 : Options Outstanding Weighted Average Exercise Price (in thousands) Outstanding at October 31, 2014 2,202 $ 36 Keysight converted at October 31, 2014 (a) 3,947 $ 20 Granted 968 $ 31 Exercised (830 ) $ 16 Forfeited and expired (60 ) $ 18 Outstanding at October 31, 2015 4,025 $ 24 (a) Awards outstanding/unvested held by Keysight employees on October 31, 2014 were converted into Keysight awards to maintain their pre-distribution intrinsic value based on Agilent’s closing stock price of $55.28 on October 31, 2014. The adjusted number of awards were calculated using the post-spin Keysight stock price of $30.80 , which is the volume-weighted average trading price of Keysight Shares over the first two trading sessions immediately after the Distribution Date, computed by dividing (i) the aggregate sales price of all shares sold over the NYSE during such two trading sessions, by (ii) the number of such sold shares. Forfeited and expired options from total cancellations in 2015 were as follows: Options canceled Weighted Average Exercise Price (in thousands) Forfeited 16 $ 27 Expired 44 $ 15 Total options canceled during 2015 60 $ 18 The options outstanding and exercisable for equity share-based payment awards at October 31, 2015 were as follows: Options Outstanding Options Exercisable Range of Exercise Prices Number Outstanding Weighted Average Remaining Contractual Life Weighted Average Exercise Price Aggregate Intrinsic Value Number Exercisable Weighted Average Remaining Contractual Life Weighted Average Exercise Price Aggregate Intrinsic Value (in thousands) (in years) (in thousands) (in thousands) (in years) (in thousands) $0 - 25 2,314 4.2 $ 19 $ 32,648 1,714 3.4 $ 19 $ 24,928 $25.01 - 30 737 8.1 $ 30 2,400 182 8.1 $ 30 591 $30.01 - 40 974 9.0 $ 31 2,020 3 8.4 $ 31 5 4,025 6.1 $ 24 $ 37,068 1,899 3.8 $ 20 $ 25,524 The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value, based on Keysight's closing stock price of $33.08 at October 31, 2015 , which would have been received by award holders had all award holders exercised their awards that were in-the-money as of that date. The total number of in-the-money awards exercisable at October 31, 2015 was approximately 1.9 million . The following table summarizes the aggregate intrinsic value of options exercised and the fair value of options granted in 2015 , 2014 and 2013 : Aggregate Intrinsic Value Weighted Average Exercise Price Per Share Value Using Black-Scholes Model (in thousands) Options exercised in fiscal 2013 $ 26,808 $ 28 Black-Scholes per share value of options granted during fiscal 2013 $ 12 Options exercised in fiscal 2014 $ 39,886 $ 30 Black-Scholes per share value of options granted during fiscal 2014 $ 19 Options exercised in fiscal 2015 $ 15,160 $ 16 Black-Scholes per share value of options granted during fiscal 2015 $ 9 As of October 31, 2015 the unrecognized share-based compensation costs for outstanding stock option awards, net of expected forfeitures, was approximately $5 million , which is expected to be amortized over a weighted average period of 2.4 years. See Note 6, "Income Taxes," for the tax impact on share-based award exercises. Non-vested Awards The following table summarizes non-vested award activity in 2015 primarily for our LTP Program and restricted stock unit awards: Shares Weighted Average Grant Date Fair Value (in thousands) Non-vested at October 31, 2014 1,422 $ 44 Keysight converted at October 31, 2014 (a) 2,552 $ 25 Granted 1,725 $ 33 Vested (1,052 ) $ 25 Forfeited (39 ) $ 29 Change in LTP Program shares vested in the year due to performance conditions (66 ) $ 28 Non-vested at October 31, 2015 3,120 $ 29 (a) Awards outstanding/unvested held by Keysight employees on October 31, 2014 were converted into Keysight awards to maintain their pre-distribution intrinsic value based on Agilent’s closing stock price of $55.28 on October 31, 2014. The adjusted number of awards were calculated using the post-spin Keysight stock price of $30.80 , which is the volume-weighted average trading price of Keysight Shares over the first two trading sessions immediately after the Distribution Date, computed by dividing (i) the aggregate sales price of all shares sold over the NYSE during such two trading sessions, by (ii) the number of such sold shares. As of October 31, 2015 the unrecognized share-based compensation cost for non-vested restricted stock awards, net of expected forfeitures, was approximately $33 million , which is expected to be amortized over a weighted average period of 2.2 years . The total fair value of restricted stock awards vested was $36 million for 2015, $29 million for 2014 and $12 million for 2013.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The domestic and foreign components of income before taxes are: Year Ended October 31, 2015 2014 2013 (in millions) U.S. operations $ (6 ) $ (18 ) $ 14 Non-U.S. operations 394 493 487 Total income before taxes $ 388 $ 475 $ 501 The provision (benefit) for income taxes is comprised of: Year Ended October 31, 2015 2014 2013 (in millions) U.S. federal taxes: Current $ 12 $ (11 ) $ 10 Deferred (7 ) 25 12 Non-U.S. taxes: Current 24 62 16 Deferred (158 ) (4 ) 3 State taxes, net of federal benefit: Current 1 9 4 Deferred 3 2 (1 ) Total provision (benefit) for income taxes $ (125 ) $ 83 $ 44 The income tax provision does not reflect potential future tax savings resulting from excess deductions associated with our various share-based award plans. The significant components of deferred tax assets and deferred tax liabilities included in the combined and consolidated balance sheet are: October 31, 2015 2014 Deferred Tax Assets Deferred Tax Liabilities Deferred Tax Assets Deferred Tax Liabilities (in millions) Inventory $ 12 $ (1 ) $ 20 $ — Intangibles 131 (15 ) 35 (6 ) Property, plant and equipment 25 (11 ) 28 (10 ) Warranty reserves 20 — 18 — Pension benefits 66 (18 ) 61 (18 ) Employee benefits, other than retirement 27 — 26 — Net operating loss, capital loss, and credit carryforwards 135 — 127 — State taxes — — 6 — Unremitted earnings of foreign subsidiaries — (33 ) — (53 ) Share-based compensation 23 — 15 — Deferred revenue 36 (3 ) 42 (1 ) Other 11 (7 ) 3 (11 ) Subtotal 486 (88 ) 381 (99 ) Tax valuation allowance (46 ) — (39 ) — Total deferred tax assets or deferred tax liabilities $ 440 $ (88 ) $ 342 $ (99 ) The significant increase in 2015 as compared to 2014 for deferred tax assets primarily relates to the $219 million in net deferred tax assets arising from the confirmation received from the Singaporean government that we would entitled to amortize the value of certain intangible property rights we received from Agilent in the separation. Through 2015, $88 million of this asset has been amortized for tax purposes. Further, the acquisition of Anite impacted the deferred tax assets and liabilities, primarily through the addition of $34 million of deferred tax assets for capital losses, which have a full valuation allowance. Lastly, due to the separation from Agilent, for fiscal 2015, Keysight is no longer reporting under the separate return methodology; therefore, current and non-current deferred tax assets decreased by approximately $4 million and $43 million , respectively. This decline was primarily related to the decrease in tax attributes of $83 million offset by a decrease in foreign unremitted earnings of approximately $53 million and valuation allowance of $36 million that are not retained by Keysight upon separation. We continue to be in discussions with Agilent regarding the allocation of certain deferred tax liability balances related to foreign unremitted earnings in accordance with the separation agreements. We record U.S. income taxes on the undistributed earnings of foreign subsidiaries unless the subsidiaries' earnings are considered permanently reinvested outside the U.S. As of October 31, 2015 we recognized a $33 million deferred tax liability for the overall residual tax expected to be imposed upon the repatriation of unremitted foreign earnings that are not considered permanently reinvested. As of October 31, 2015 the cumulative amount of undistributed earnings considered permanently reinvested was $1.1 billion . No deferred tax liability has been recognized on the basis difference created by such earnings since it is our intention to utilize those earnings in the company’s foreign operations. Because of the availability of U.S. foreign tax credits, the determination of the unrecognized deferred tax liability on these earnings is not practicable. The breakdown between current and long-term deferred tax assets and deferred tax liabilities was as follows for the years 2015 and 2014 : October 31, 2015 2014 (in millions) Current deferred tax assets $ 74 $ 83 Long-term deferred tax assets 295 163 Current deferred tax liabilities (included within other accrued liabilities) (2 ) (1 ) Long-term deferred tax liabilities (included within other long-term liabilities) (15 ) (2 ) Total $ 352 $ 243 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 valuation allowance decreased by $2 million in the year ended October 31, 2014. In the fourth quarter of 2014 management concluded that the valuation allowance of our U.K. deferred tax assets is no longer needed primarily due to the emergence from cumulative losses in recent years, the return to sustainable U.K. operating profits and the expectation of sustainable profitability in future periods. Accordingly, we recognized a non-recurring tax benefit of $6 million relating to the U.K. valuation allowance reversal. The valuation allowance as of October 31, 2015 of $46 million is mainly related to deferred tax assets for capital losses in the U.K. We will maintain a valuation allowance until sufficient positive evidence exists to support reversal. The increase in valuation allowance from October 31, 2014 to October 31, 2015 includes a reduction in the valuation allowance for amounts that are not retained by Keysight upon separation offset by the valuation allowance on certain acquired deferred tax assets. At October 31, 2015, we had U.S. federal net operating loss carryforwards from acquired entities of approximately $3 million and tax credit carryforwards of approximately $1 million . The federal net operating losses expire in 2035 , and the federal tax credits expire in 2025 , if not utilized. The federal loss and credit carryforwards are subject to change of ownership limitations provided by the Internal Revenue Code and similar state provisions. At October 31, 2015, we also had foreign net operating loss carryforwards of approximately $1,519 million . Of this foreign loss, $39 million will expire in years beginning 2019 through 2023 if not utilized. The remaining $1,480 million has an indefinite life, of which $13 million relates to acquired entities. At October 31, 2015, we had foreign capital loss carryforwards of approximately $177 million with an indefinite life and $2 million of tax credits in foreign jurisdictions with an indefinite life, of which $170 million and $2 million relate to acquired entities, respectively. Some of the foreign losses are subject to annual loss limitation rules. These annual loss limitations in the U.S. and foreign jurisdictions may result in the expiration or reduced utilization of the net operating losses. The authoritative guidance prohibits recognition of a deferred tax asset for excess tax benefits related to stock and stock option plans that have not yet been realized through reduction in income taxes payable. Such unrecognized deferred tax benefit totals zero as of October 31, 2015 and will be accounted for as a credit to shareholders' equity, if and when realized, through a reduction in income taxes payable. We have recognized approximately $4 million as a credit to shareholders' equity for cumulative excess tax benefits related to stock and stock option plans that have been realized as of October 31, 2015. The differences between the U.S. federal statutory income tax rate and our effective tax rate are: Year Ended October 31, 2015 2014 2013 (in millions) Profit before tax times statutory rate $ 136 $ 166 $ 175 State income taxes, net of federal benefit 3 6 2 Non-U.S. income taxed at different rates (107 ) (113 ) (147 ) Singapore tax incentives through amortization (219 ) — — Retroactive Singapore tax rate incentive impact (15 ) Repatriation of foreign earnings — 62 8 Foreign earnings not considered indefinitely reinvested 33 — — Change in unrecognized tax benefits 33 (39 ) 6 Valuation allowances — (5 ) — Other, net 11 6 — Provision (benefit) for income taxes $ (125 ) $ 83 $ 44 Effective tax rate (32 )% 18 % 9 % We benefit from tax incentives in several different jurisdictions, most significantly in Singapore, and several jurisdictions have granted or are anticipated to grant us tax incentives that require renewal at various times in the future. The tax incentives provide lower rates of taxation on certain classes of income and require various thresholds of investments and employment or specific types of income in those jurisdictions. The tax incentives are due for renewal between 2016 and 2023. The impact of the tax incentives decreased income taxes by $250 million , $40 million and $68 million in 2015, 2014, and 2013, respectively. The benefit of the tax incentives on net income per share (diluted) was approximately $1.46 , $0.41 , and $0.57 in 2015, 2014 and 2013, respectively. Of the $1.46 benefit of the tax incentives on net income per share (diluted) in 2015, $1.21 benefit relates to one- time items due to the retroactive granting of the Singapore tax incentives. For 2015, the effective tax rate was a benefit of 32 percent , which is lower than the U.S. statutory rate primarily due to the retroactive benefit of two tax incentives in Singapore approved during 2015. Also, the tax rate was lower than the U.S. statutory rate due to the mix of earnings in the non-U.S. jurisdictions taxed at lower statutory tax rates. For 2014, the effective tax rate was 18 percent . The 18 percent effective tax rate is lower than the U.S. statutory rate primarily due to the mix of earnings in non-U.S. jurisdictions taxed at lower statutory tax rates; in particular Singapore, where we benefited from tax incentives for the first three quarters of 2014, which resulted in $40 million lower income tax expense. The 2014 rate was also favorably impacted by a $55 million benefit from a prior year reserve release, which was offset by $62 million tax expense as a result of the repatriation of foreign earnings. For 2013 the effective tax rate was 9 percent . The 9 percent effective tax rate is lower than the U.S. statutory rate primarily due to the mix of earnings in non-U.S. jurisdictions taxed at lower statutory rates; in particular Singapore where we benefited from tax incentives. The breakdown between current and long-term income tax assets and liabilities, excluding deferred tax assets and liabilities, was as follows for the years 2015 and 2014 : October 31, 2015 2014 (in millions) Current income tax liabilities (included within income and other taxes payable) $ (3 ) $ (60 ) Long-term income tax liabilities (included within other long-term liabilities) (14 ) (82 ) Total $ (17 ) $ (142 ) The calculation of our tax liabilities involves dealing with 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. The ultimate resolution of tax uncertainties may differ from what is currently estimated, which could result in a material impact on income tax expense. If our estimate of income tax liabilities proves to be less than the ultimate assessment, a further charge to expense would be required. If events occur and the payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. The aggregate changes in the balances of our unrecognized tax benefits including all federal, state and foreign tax jurisdictions are as follows: 2015 2014 2013 (in millions) Balance, beginning of year $ 129 $ 173 $ 162 Reductions due to spin transaction (113 ) — — Additions due to acquisition 2 — — Additions for tax positions related to the current year 34 10 9 Additions for tax positions from prior years 2 9 5 Reductions for tax positions from prior years (4 ) (59 ) (2 ) Settlements with taxing authorities — (1 ) — Statute of limitations expirations — (3 ) (1 ) Balance, end of year $ 50 $ 129 $ 173 As of October 31, 2015 we had $50 million of unrecognized tax benefits which, if recognized, would affect our effective tax rate. Under the terms of the tax matters agreement, the unrecognized tax benefits as of separation differed from the amount allocated using the separate return methodology, therefore, a $113 million reduction in the unrecognized tax benefits occurred between October 31, 2014 and October 31, 2015 upon separation. We recognized a tax expense of zero , a tax expense of $4 million and a tax expense of $2 million of interest and penalties related to unrecognized tax benefits in 2015 , 2014 and 2013 , respectively. Interest and penalties accrued as of October 31, 2015 and 2014 were $1 million and $8 million , respectively. For the majority of our entities, the open tax years for the IRS, state and most foreign audit authorities are from August 1, 2014, through the current tax year. For certain historical Agilent foreign entities that Keysight retained as part of the separation, the tax years generally remain open back to the year 2005. For certain entities acquired during 2015, the tax years also remain open back to the year 2005. 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.

Basic and diluted net income per share for the year ended October 31, 2014 and 2013 is calculated using the shares distributed on November 1, 2014. 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, the tax benefits or shortfalls recorded to additional paid-in capital and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options and unamortized share-based compensation expense and tax benefits or shortfalls collectively are assumed proceeds to be used to repurchase hypothetical shares. An increase in the fair market value of the company's common stock can result in a greater dilutive effect from potentially dilutive awards. The total number of share-based awards issued in 2015 was 2 million . We exclude stock options with exercise prices greater than the average market price of our common stock from the calculation of diluted earnings per share because their effect would be anti-dilutive. For the year ended October 31, 2015, no options to purchase shares were excluded from the calculation of diluted earnings per share. In addition, we also exclude from the calculation of diluted earnings per share, stock options, ESPP, LTP Program and restricted stock awards, whose combined exercise price, unamortized fair value and excess tax benefits or shortfalls collectively were greater than the average market price of our common stock because their effect would also be anti-dilutive. For the year ended October 31, 2015, we excluded 46,300 shares from the calculation of diluted earnings per share.

During the year, we also recorded $246 million of additions to other intangibles related to the same acquisitions. We recorded $3 million of foreign exchange translation impact to other intangibles in 2015. In 2014, we recorded additions to goodwill of $5 million related to the acquisition of a business. During the year, we also recorded $6 million of additions to other intangibles related to the same business. Amortization of intangible assets was $15 million in 2015, $8 million in 2014, and $9 million in 2013. In addition, we recorded $1 million of impairments of other intangibles related to the cancellation of an in-process research and development project during 2013. Future amortization expense related to existing finite-lived purchased intangible assets is estimated to be $43 million in 2016, $39 million for 2017, $36 million for 2018, $36 million for 2019, $36 million in 2020, and $44 million thereafter.

Trading securities are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. Investments designated as available-for-sale are reported at fair value, with unrealized gains and losses, net of tax, included in stockholders' equity. In June 2015, we purchased $7 million of preferred stock of a privately held radio frequency microstructure company. We are accounting for this investment using the cost method. Investments in available-for-sale securities at estimated fair value were as follows: October 31, 2015 October 31, 2014 Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value (in millions) Equity securities $ 15 $ 26 $ — $ 41 $ 15 $ 20 $ — $ 35 All of our investments, excluding trading securities, are subject to periodic impairment review. The impairment analysis requires significant judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of the investment. We consider various factors in determining whether an impairment is other-than-temporary, including the severity and duration of the impairment, forecasted recovery, the financial condition and near-term prospects of the investee, and our ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. In 2015, other cost method investments with a carrying amount of $4 million were written down to their fair value of zero , resulting in an impairment charge of $4 million , which is included in other income (expense), net. There were no impairments recognized in 2014 and 2013. There were no realized gains on the sale of available-for-sale securities in 2015, 2014 and 2013. Net unrealized gains and losses on our trading securities portfolio were $1 million of unrealized gains in 2015 , $1 million of unrealized gains in 2014 and $2 million of unrealized gains in 2013 . Realized gains from the sale of cost method securities was zero for 2015 , 2014 and 2013 .

FAIR VALUE MEASUREMENTS

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	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 the use of 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, 2015 were as follows: Fair Value Measurement at October 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in millions) Assets: Short-term Cash equivalents (money market funds) $ 295 $ 295 $ — $ — Derivative instruments (foreign exchange contracts) 1 — 1 — Long-term Trading securities 12 12 — — Available-for-sale investments 41 41 — — Total assets measured at fair value $ 349 $ 348 $ 1 $ — Liabilities: Short-term Derivative instruments (foreign exchange contracts) $ 10 $ — $ 10 $ — Long-term Deferred compensation liability 12 — 12 — Total liabilities measured at fair value $ 22 $ — $ 22 $ — Financial assets and liabilities measured at fair value on a recurring basis as of October 31, 2014 were as follows: Fair Value Measurement at October 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in millions) Assets: Short-term Cash equivalents (money market funds) $ 634 $ 634 $ — $ — Derivative instruments (foreign exchange contracts) 9 — 9 — Long-term Trading securities 13 13 — — Available-for-sale investments 35 35 — — Total assets measured at fair value $ 691 $ 682 $ 9 $ — Liabilities: Short-term Derivative instruments (foreign exchange contracts) $ 3 $ — $ 3 $ — Long-term Deferred compensation liability 13 — 13 — Total liabilities measured at fair value $ 16 $ — $ 16 $ — Our money market funds, trading securities, and available-for-sale investments are generally valued using quoted market prices and therefore are classified within Level 1 of the fair value hierarchy. 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. Our deferred compensation liability is classified as Level 2 because although the values are not directly based on quoted market prices, the inputs used in the calculations are observable. Trading securities and deferred compensation liability are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in net income. Investments designated as available-for-sale and certain derivative instruments are reported at fair value, with unrealized gains and losses, net of tax, included in stockholders' equity. Realized gains and losses from the sale of these instruments are recorded in net income.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES We are exposed to foreign currency exchange rate fluctuations and interest rate changes in the normal course of our business. As part of risk management strategy, we use derivative instruments, primarily forward contracts and purchased options to hedge economic and/or accounting exposures resulting from changes in foreign currency exchange rates. Prior to the Capitalization, there were no derivatives contracts legally held by us and the below disclosures represent the activity pertaining to the contracts entered into by us subsequently. 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 between one and 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 effective portion of the derivative instrument are recognized in accumulated other comprehensive income. Amounts associated with cash flow hedges are reclassified to cost of sales in the combined and consolidated statement of operations when the forecasted transaction occurs. 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 to other income (expense), net in the current period. Changes in the fair value of the ineffective portion of derivative instruments are recognized in earnings in the combined and consolidated statement of operations in the current period. We record the premium paid (time value) of an option on the date of purchase as an asset. For options designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness and are recognized in other income (expense) over the life of the option contract. The income statement charge for ineffectiveness in 2015, 2014 and 2013 was not significant. 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 combined and consolidated statement of operations, in the current period, along with the offsetting foreign currency gain or loss on the underlying assets or liabilities. In connection with the acquisition of Anite plc ("Anite"), which closed on August 13, 2015 (see Note 3, "Acquisitions"), Keysight entered into foreign currency forward contracts to mitigate the currency exchange risk associated with the payment of the purchase price in British Pound ("GBP") currency. The aggregate notional amount of the currencies hedged was $608 million . These foreign exchange contracts did not qualify for hedge accounting treatment and were not designated as hedging instruments. The resulting loss on settlement, on the date of acquisition, was $2 million and was recorded in other income (expense) in the consolidated statement of operations for the year ended October 31, 2015. 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. A number of our derivative agreements contain threshold limits to the net liability position with counterparties and are dependent on our corporate credit rating determined by the major credit rating agencies. The counterparties to the derivative instruments may request collateralization, in accordance with derivative agreements, on derivative instruments in net liability positions. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position as of October 31, 2015 was $10 million . The credit-risk-related contingent features underlying these agreements had not been triggered as of October 31, 2015 . There were 87 foreign exchange forward contracts open as of October 31, 2015 and designated as cash flow hedges. There were 76 foreign exchange forward contracts and 1 foreign exchange option contract open as of October 31, 2015 not designated as hedging instruments. The aggregated notional amounts by currency and designation as of October 31, 2015 were as follows: Derivatives in Cash Flow Hedging Relationships Derivatives Not Designated as Hedging Instruments Forward Contracts Option Contracts Forward Contracts Option Contracts Currency Buy/(Sell) Buy/(Sell) Buy/(Sell) Buy/(Sell) (in millions) Euro $ — $ — $ 92 42 British Pound — — 14 — Singapore Dollar 9 — — — Malaysian Ringgit 81 — (5 ) — Japanese Yen (76 ) — (29 ) — Other — — 7 — $ 14 $ — $ 79 $ 42 Derivative instruments are subject to master netting arrangements and are disclosed gross in the balance sheet.

Restructuring and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING We initiated a targeted workforce reduction program in July 2015 that is expected to reduce Keysight's total headcount by approximately 104 employees, representing approximately 1 percent of our global workforce. The timing and scope of workforce reductions will vary based on local legal requirements. This targeted workforce management program is designed to restructure our operations and cost structure for optimization of resources and cost savings. We also announced a Pre-retirement notification program for retirement-eligible employees to provide early notice of their planned retirement in return for severance benefits. The program is entirely voluntary and can be initiated only by an employee. Approximately 160 employees of our total workforce opted for early retirement under this program as of October 31, 2015. When completed, the restructuring programs are expected to result in operational savings and efficiency while maintaining our focus on growing the business. We expect to complete a majority of these actions by the end of first quarter of fiscal year 2016. A summary of balances and restructuring activity is shown in the table below: Workforce reduction U.S. Pre-retirement Plan (in millions) Balance as of October 31, 2014 $ 1 $ — Income statement expense 8 8 Cash payments (5 ) (6 ) Balance as of October 31, 2015 $ 4 $ 2 The restructuring accrual of $4 million at October 31, 2015 relating to workforce reduction are recorded in other accrued liabilities, and $2 million related to the Pre-Retirement Notification program is included in employee compensation and benefits in the condensed consolidated balance sheet.

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract]
RETIREMENT PLANS AND POST-RETIREMENT PENSION PLANS	RETIREMENT PLANS AND POST-RETIREMENT PENSION PLANS General. Prior to the Capitalization, substantially all of our employees were covered under various defined benefit and/or defined contribution retirement plans sponsored by Agilent. All defined benefit retirement plans and the post-retirement health care plan were considered multi-employer plans. As a result, no asset or liability was recorded by us to recognize the funded status in our combined and consolidated balance sheet until the Capitalization. At the Capitalization, the assets and liabilities of these plans that were allocable to Keysight employees were transferred to Keysight plans. Plan assets of $ 2,037 million, benefit obligations of $ 2,157 million and $ 344 million of accumulated other comprehensive loss ($ 270 million, net of tax) were recorded for the plans transferred to us. In 2015, additional plan assets of $9 million that were allocable to Keysight employees were transferred to Keysight plans by Agilent. Substantially all 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 which are based on an employee's base or target pay during the years of employment and on length of service. For eligible service through October 31, 1993, the benefit payable under the RP is reduced by any amounts due to the eligible employee under our defined contribution Deferred Profit-Sharing Plan ("DPSP"), which was closed to new participants as of November 1993. 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." As of October 31, 2015 , the fair value of plan assets of the DPSP for U.S. employees was $300 million . Note that the projected benefit obligation for the DPSP equals the fair value of plan assets. Eligible employees outside the U.S. generally receive retirement benefits under various retirement plans ("Non-U.S. Plans") based upon factors such as years of service and/or employee compensation levels. Eligibility is generally determined in accordance with local statutory requirements. 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. Under the 401(k) Plan, we provide matching contributions to employees up to a maximum of 4 percent of an employee's annual eligible compensation. The maximum contribution to the 401(k) Plan is 50 percent of an employee's annual eligible compensation, subject to regulatory limitations. The 401(k) Plan employer expense included in income from operations was $14 million in 2015 and $12 million in 2014, including allocated costs and contributions made from Agilent of $9 million . Agilent allocated costs and made contributions to the 401(k) Plan on our behalf in the amount of $12 million for the year ended October 31, 2013. Employees hired on or after August 1, 2015 are not eligible to participate in the RP or the U.S. Post-Retirement Benefit Plan. We provide matching contributions to these employees under the 401(k) Plan up to a maximum of 6 percent of the employee's annual eligible compensation. 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 Keysight Technologies, Inc. Health Plan for Retirees ("U.S. Post-Retirement Benefit Plan"). Eligible retirees who were less than age 50 as of January 1, 2005 and who retire after age 55 with 15 or more years of service (age 54 with 14 or more years of service for workforce managed terminations) are eligible for a fixed amount which can be utilized to pay for premiums under a Keysight sponsored pre-Medicare medical plan, non-Keysight sponsored medical, dental and vision plans purchased in the individual insurance market, as well as Medicare Part A, Medicare Part B and prescription drug premiums. Premiums to purchase other employer-sponsored coverage are not eligible for reimbursement. Eligible retirees who were at least age 50 as of January 1, 2005 and who retire after age 55 with 15 or more years of service (age 54 with 14 or more years of service for workforce managed terminations) currently choose from managed-care or indemnity options, with the company subsidization level or stipend dependent on a number of factors including eligibility and length of service. Grandfathered retirees receive a fixed monthly subsidy toward pre- 65 premium costs (subsidy capped at 2011 levels) and a fixed monthly stipend post- 65 . The subsidy amounts will not increase. Components of net periodic cost. 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. For the years ended October 31, 2015 , 2014 and 2013 , 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 2015 2014 2013 2015 2014 2013 2015 2014 2013 (in millions) Net periodic benefit cost (benefit) Service cost — benefits earned during the period $ 22 $ 5 $ — $ 18 $ 4 $ — $ 1 $ — $ — Interest cost on benefit obligation 20 5 — 41 11 — 7 2 — Expected return on plan assets (38 ) (10 ) — (72 ) (19 ) — (13 ) (4 ) — Amortization of net actuarial loss 4 1 — 27 7 — 12 2 — Amortization of prior service credit (7 ) (1 ) — (1 ) — — (21 ) (5 ) — Net periodic benefit cost (benefit) 1 — — 13 3 — (14 ) (5 ) — Allocated benefit cost (benefit) from Agilent — 3 9 — 9 23 — (9 ) (10 ) Total periodic benefit cost (benefit) $ 1 $ 3 $ 9 $ 13 $ 12 $ 23 $ (14 ) $ (14 ) $ (10 ) Other changes in plan assets and benefit obligations recognized in other comprehensive (income) loss Prior service credits assumed at the Capitalization $ — $ (33 ) $ — $ — $ (3 ) $ — $ — $ (102 ) $ — Net actuarial loss assumed at the Capitalization — 40 — — 367 — — 75 — Net actuarial loss 57 5 — 51 39 — 31 7 — Amortization of net actuarial loss (4 ) (1 ) — (27 ) (7 ) — (12 ) (2 ) — Amortization of prior service credit 7 1 — 1 — — 21 5 — Foreign currency — — — 24 9 — — — — Total recognized in other comprehensive (income) loss $ 60 $ 12 $ — $ 49 $ 405 $ — $ 40 $ (17 ) $ — Total recognized in net periodic benefit cost (benefit) and other comprehensive (income) loss $ 61 $ 15 $ 9 $ 62 $ 417 $ 23 $ 26 $ (31 ) $ (10 ) Funded status. As of October 31, 2015 and 2014 , the funded status of the defined benefit and post-retirement benefit plans was as follows: U.S. Defined Benefit Plans Non-U.S. Defined Benefit Plans U.S. Post-Retirement Benefit Plan 2015 2014 2015 2014 2015 2014 (in millions) Change in fair value of plan assets: Fair value — beginning of year $ 491 $ — $ 1,318 $ — $ 187 $ — Assets received from Agilent — 490 9 1,358 — 189 Actual return on plan assets 7 7 81 46 2 2 Employer contributions — — 48 10 1 — Benefits paid (23 ) (6 ) (33 ) (9 ) (11 ) (4 ) Currency impact — — (80 ) (87 ) — — Fair value — end of year $ 475 $ 491 $ 1,343 $ 1,318 $ 179 $ 187 Change in benefit obligation: Benefit obligation — beginning of year $ 514 $ — $ 1,429 $ — $ 206 $ — Liabilities assumed from Agilent — 508 — 1,446 — 203 Service cost 22 5 18 4 1 — Interest cost 20 5 41 11 7 2 Plan amendment — — — (1 ) — — Actuarial loss 27 2 60 70 20 5 Benefits paid (24 ) (6 ) (33 ) (9 ) (11 ) (4 ) Currency impact — — (90 ) (92 ) — — Benefit obligation — end of year $ 559 $ 514 $ 1,425 $ 1,429 $ 223 $ 206 Underfunded status of PBO $ (84 ) $ (23 ) $ (82 ) $ (111 ) $ (44 ) $ (19 ) Amounts recognized in the consolidated balance sheet consist of: Other assets $ — $ — $ 57 $ 48 $ — $ — Employee compensation and benefits (1 ) (1 ) — — — — Retirement and post-retirement benefits (83 ) (22 ) (139 ) (159 ) (44 ) (19 ) Net liability $ (84 ) $ (23 ) $ (82 ) $ (111 ) $ (44 ) $ (19 ) Amounts recognized in accumulated other comprehensive income (loss): Actuarial losses $ 97 $ 44 $ 430 $ 408 $ 99 $ 80 Prior service credits (25 ) (32 ) (4 ) (3 ) (76 ) (97 ) Total $ 72 $ 12 $ 426 $ 405 $ 23 $ (17 ) The amounts in accumulated other comprehensive income expected to be amortized into net periodic benefit cost (benefit) during 2016 are as follows: U.S. Defined Benefit Plans Non-U.S. Defined Benefit Plans U.S. Post-Retirement Benefit Plan (in millions) Amortization of net prior service credit $ (7 ) $ (1 ) $ (17 ) Amortization of actuarial net loss $ 9 $ 27 $ 20 Investment policies and strategies as of October 31, 2015 . In the U.S., our RP and U.S. Post-Retirement Benefit Plan target asset allocations are approximately 80 percent to equities and approximately 20 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 assumption of a reasonable 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 37 to 60 percent to equities, from 40 to 60 percent to fixed income investments, from zero to 6 percent to real estate investments and from zero to 14 percent to cash, depending on the plan. All plans' assets are broadly diversified. Due to fluctuations in capital markets, our actual allocations of plan assets at October 31, 2015 , 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. 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 13, "Fair Value Measurements." Cash and Cash Equivalents - Cash and cash equivalents consist of short-term investment funds. The funds also invest 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 classified as Level 1 investments except when the cash and cash equivalents are held in commingled funds, which have a daily net value derived from quoted prices for the underlying securities in active markets; these are classified as Level 2 investments. Equity - Some equity securities consisting of common and preferred stock are held in commingled funds, which have daily net asset values derived from quoted prices for the underlying securities in active markets; these are classified as Level 2 investments. Commingled funds which have quoted prices in active markets are classified as Level 1 investments. Fixed Income - Some of the fixed income securities are held in commingled funds, which have daily net asset values derived from the underlying securities; these are classified as Level 2 investments. Commingled funds which have quoted prices in active markets are classified as Level 1 investments. Other Investments - Other investments include property-based pooled vehicles which invest in real estate. Market net asset values are regularly published in the financial press or on corporate websites and so these investments are classified as Level 2 and 3. The following table presents the fair value of U.S. Defined Benefit Plans assets classified under the appropriate level of the fair value hierarchy as of October 31, 2015 and 2014: Fair Value Measurement at October 31, 2015 Using October 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in millions) Cash and Cash Equivalents $ 4 $ 1 $ 3 $ — Equity 374 94 280 — Fixed Income 97 21 76 — Other Investments — — — — Total assets measured at fair value $ 475 $ 116 $ 359 $ — Fair Value Measurement at October 31, 2014 Using October 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (in millions) Cash and Cash Equivalents $ 6 $ 1 $ 5 $ — Equity 365 86 279 — Fixed Income 120 40 80 — Other Investments — — — — Total assets measured at fair value $ 491 $ 127 $ 364 $ — For U.S. Defined Benefit Plans, there was no activity relating to assets measured at fair value using significant unobservable inputs (Level 3) during 2015 and 2014.

During fiscal year 2016, we do not expect to contribute to the U.S. Defined Benefit Plans, and expect to contribute $43 million to the Non-U.S. Defined Benefit Plans and $2 million to the U.S. Post-Retirement Benefit Plan. The following table presents expected future benefit payments for the next 10 years . U.S. Defined Benefit Plans Non-U.S. Defined Benefit Plans U.S. Post-Retirement Benefit Plan (in millions) 2016 $ 35 $ 35 $ 17 2017 $ 38 $ 37 $ 17 2018 $ 39 $ 40 $ 18 2019 $ 42 $ 45 $ 17 2020 $ 47 $ 48 $ 17 2021 - 2025 $ 254 $ 316 $ 80 Assumptions . The assumptions used to determine the benefit obligations and expense 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 - October 31. The U.S. discount rates at October 31, 2015 and 2014 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 at October 31, 2015 were determined using spot rates along the yield curve to calculate disaggregated discount rates. In addition, we used this method to calculate two components of the periodic benefit cost: service cost and interest cost. The Non-U.S. discount rates at October 31, 2014 were generally based on published rates for high-quality corporate bonds. 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 for the year ended October 31, 2015 and 2014 were as follows: For years ended October 31, 2015 2014 U.S. Defined Benefit Plans: Discount rate 4.00% 4.00% Average increase in compensation levels 3.50% 3.50% Expected long-term return on assets 8.00% 8.00% Non-U.S. Defined Benefit Plans: Discount rate 1.50-4.00% 1.75-4.25% Average increase in compensation levels 2.50-3.25% 2.50-3.25% Expected long-term return on assets 4.00-6.50% 4.00-6.50% U.S. Post-Retirement Benefits Plan: Discount rate 3.75% 4.00% Expected long-term return on assets 8.00% 8.00% Current medical cost trend rate 8.00% 8.00% Ultimate medical cost trend rate 3.50% 3.50% Medical cost trend rate decreases to ultimate rate in year 2028 2028 Assumptions used to calculate the benefit obligation as of October 31, 2015 and 2014 were as follows: As of the years ended October 31, 2015 2014 U.S. Defined Benefit Plans: Discount rate 4.00% 4.00% Average increase in compensation levels 3.00% 3.50% Non-U.S. Defined Benefit Plans: Discount rate 0.76-3.80% 1.50-4.00% Average increase in compensation levels 2.50-3.50% 2.50-3.25% U.S. Post-Retirement Benefits Plan: Discount rate 4.00% 3.75% Current medical cost trend rate 7.00% 8.00% Ultimate medical cost trend rate 3.50% 3.50% Medical cost trend rate decreases to ultimate rate in year 2028 2028 Health care trend rates do 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, 2015 and 2014.

Guarantees [Abstract]
GUARANTEES	GUARANTEES Standard Warranty The standard warranty term for most of our products from the date of delivery is typically three years, which increased from one year in the second quarter of fiscal 2013. We accrue for standard warranty costs based on historical trends in warranty charges as a percentage of net product shipments. 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. Activity related to the standard warranty accrual, which is included in other accrued and other long-term liabilities in our combined and consolidated balance sheet, is as follows: Years Ended October 31, 2015 2014 (in millions) Beginning balance $ 51 $ 38 Accruals for warranties, including change in estimates 33 46 Settlements made during the period (31 ) (33 ) Ending balance 53 $ 51 Accruals for warranties due within one year $ 34 $ 34 Accruals for warranties due after one year 19 17 Ending balance as of October 31 $ 53 $ 51 Indemnifications to Agilent In connection with our separation from Agilent, we agreed to indemnify Agilent against certain damages and expenses that it might incur in the future. These indemnifications primarily cover damages relating to liabilities of the electronic measurement business of Agilent which was contributed to Keysight. Additionally, if the distribution of Keysight common stock to the Agilent shareholders were determined to be taxable for U.S. federal income tax purposes, Agilent and its shareholders that are subject to U.S. federal income tax could incur significant U.S. federal income tax liabilities. If such determination is the result of our taking or failing to take certain actions, then under the tax matters agreement with Agilent, we are generally required to indemnify Agilent against such tax liabilities. Pursuant to the tax matters agreement, we may also be required to indemnify Agilent for other contingent tax liabilities, which could materially adversely affect our financial position. In our opinion, the fair value of these indemnification obligations was not material as of October 31, 2015 . Indemnifications to Avago In connection with the sale of Agilent's semiconductor products business in December 2005, Agilent agreed to indemnify Avago, its affiliates and other related parties against certain damages and expenses that it might incur in the future. The continuing indemnifications primarily cover damages and expenses relating to liabilities of the businesses that Agilent retained and did not transfer to Avago, as well as pre-closing taxes and other specified items. In connection with our separation from Agilent, we have agreed to indemnify Agilent in connection with the indemnification obligations of Agilent with respect to Avago. In our opinion, the fair value of these indemnification obligations was not material as of October 31, 2015 . Indemnifications to Verigy In connection with the spin-off of Verigy, Agilent agreed to indemnify Verigy and its affiliates against certain damages which it might incur in the future. These indemnifications primarily cover damages relating to liabilities of the businesses that Agilent did not transfer to Verigy, liabilities that might arise under limited portions of Verigy's IPO materials that relate to Agilent, and costs and expenses incurred by Agilent or Verigy to effect the IPO, arising out of the distribution of Agilent's remaining holding in Verigy ordinary shares to Agilent's stockholders, or incurred to effect the separation of the semiconductor test solutions business from Agilent to the extent incurred prior to the separation on June 1, 2006. On July 4, 2011, Verigy announced the completion by Advantest Corporation of its acquisition of Verigy. Verigy operates as a wholly-owned subsidiary of Advantest and Agilent's indemnification obligations to Verigy should be unaffected. In connection with our separation from Agilent, we have agreed to indemnify Agilent in connection with the indemnification obligations of Agilent with respect to Verigy. In our opinion, the fair value of these indemnification obligations was not material as of October 31, 2015 . Indemnifications to Hewlett-Packard Agilent has given multiple indemnities to Hewlett-Packard ("HP") in connection with Agilent's activities prior to its spin-off from HP for the businesses that constituted Agilent prior to the spin-off. These indemnifications cover a variety of aspects of Agilent's business, including, but not limited to, employee, tax, intellectual property and environmental matters. The agreements containing these indemnifications have been previously disclosed as exhibits to Agilent's registration statement on Form S-1 filed on August 16, 1999. As part of our separation from Agilent, we have agreed to assume these indemnification obligations of Agilent relating to the electronic measurement business with respect to HP. In our opinion, the fair value of these indemnification obligations was not material as of October 31, 2015 . 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 which provide for indemnification of these directors and officers under similar circumstances and under additional circumstances. The indemnification obligations are more fully described in the by-laws and the indemnification agreements. 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. Historically, we have not made payments related to these obligations, and the fair value for these indemnification obligations was not material as of October 31, 2015 . 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 the associated estimated fair value of the liability was not material as of October 31, 2015 . In connection with the previous sales of several of Agilent’s businesses, Agilent agreed to indemnify the buyers of such businesses, their respective affiliates and other related parties against certain damages that they might incur in the future. The continuing indemnifications primarily cover damages relating to liabilities of the businesses that Agilent retained and did not transfer to the buyers, as well as other specified items. In connection with our separation from Agilent, we agreed to assume the indemnification obligations of Agilent to the extent that the retained businesses were part of the electronic measurement business. In our opinion, the fair value of these indemnification obligations was not material as of October 31, 2015.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Description of segments. We provide core electronic design and test solutions to the communications and electronics industries. We have two reportable operating segments, measurement solutions and customer support and services. The two operating segments were determined based primarily on how the chief operating decision maker views and evaluates our operations. Operating results are regularly reviewed by the chief operating decision maker to make decisions about resources to be allocated to the segment and to assess its 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. A description of our two reportable segments is as follows: Our measurement solutions business provides electronic measurement instruments and systems with related software and software design tools that are used in the design, development, manufacture, installation, deployment and operation of electronics equipment. We provide startup assistance, consulting, optimization and application support throughout the customer's product lifecycle. The customer support and services business provides hardware repair and calibration services and facilitates the resale of used equipment. Our customer support and services business enables our customers to maximize the value from their electronic measurement equipment and strengthens customer loyalty. Providing these services assures a high level of instrument performance and availability while minimizing the cost of ownership and downtime. A significant portion of the segments' expenses arise from shared services and infrastructure that we have historically provided to the segments in order to realize economies of scale and to efficiently use resources. These expenses, collectively called corporate charges, include costs of centralized research and development, legal, accounting, real estate, insurance services, information technology services, finance, human resources and other corporate infrastructure expenses. Charges are allocated to the segments, and the allocations have been 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. 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, restructuring and asset impairment charges, investment gains and losses, interest income, interest expense, acquisition and integration costs, separation and related costs, acquisition related fair value adjustments, non-cash amortization and other items as noted in the reconciliations below.

OVERVIEW AND SUMMARY OF SIGNI33

OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Oct. 31, 2015
Accounting Policies [Abstract]
Principles of consolidation	The combined and consolidated financial statements include the accounts of the company and our wholly- and majority-owned subsidiaries. All significant inter-company transactions have been eliminated. All significant transactions between us and other businesses of Agilent are included in these combined and consolidated financial statements. All inter-company transactions prior to the Capitalization are considered to be effectively settled for cash in the combined and consolidated statement of cash flows at the time the transaction is recorded.
Use of estimates	The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our combined and 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 best knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. 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, allocation methods and allocated expenses from Agilent prior to the separation, valuation of goodwill and other intangible assets, share-based compensation, retirement and post-retirement plan assumptions, restructuring, warranty and accounting for income taxes.
Revenue recognition	We enter into agreements to sell products (hardware and/or software), services and other arrangements (multiple-element arrangements) that include combinations of products and services. We recognize revenue, net of trade discounts and allowances, provided that (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) the price is fixed or determinable and (4) collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer, for products, or when the service has been provided. We consider the price to be fixed or determinable when the price is not subject to refund or adjustments. We consider arrangements with extended payment terms not to be fixed or determinable, and accordingly we defer revenue until amounts become due. At the time of the transaction, we evaluate the creditworthiness of our customers to determine the appropriate timing of revenue recognition. Product revenue. Our product revenue is generated predominantly from the sales of various types of test equipment and associated software. Product revenue, including sales to resellers and distributors, is reduced for estimated returns, when appropriate. For sales or arrangements that include customer-specified acceptance criteria, including those where acceptance is required upon achievement of performance milestones, revenue is recognized after the acceptance criteria have been met. For products that include installation, if the installation meets the criteria to be considered a separate element, product revenue is recognized upon delivery, and recognition of installation revenue is delayed until the installation is complete. Otherwise, neither the product nor the installation revenue is recognized until the installation is complete. Where software is licensed separately, revenue is recognized when the software is delivered and has been transferred to the customer or, in the case of electronic delivery of software, when the customer is given access to the licensed software programs. We also evaluate whether collection of the receivable is probable, the fee is fixed or determinable and whether any other undelivered elements of the arrangement exist on which a portion of the total fee would be allocated based on vendor-specific objective evidence ("VSOE"). When VSOE is not available we then use third-party evidence ("TPE") or management's best estimate of selling price ("ESP"). Service revenue. Revenue from services includes repair and calibration services, extended warranty, customer and software support, consulting, training and education. Service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer. For example, customer support contracts are recognized rateably over the contractual period, while training revenue is recognized as the training is provided to the customer. In addition, the four revenue recognition criteria described above must be met before service revenue is recognized. Revenue recognition for arrangements with multiple deliverables. Our multiple-element arrangements are generally comprised of a combination of measurement instruments, installation or other start-up services, and/or software and/or support or services. Hardware and software elements are typically delivered at the same time and revenue is recognized upon delivery and acceptance, if required, once title and risk of loss pass to the customer. Delivery of installation, start-up services and other services varies based on the complexity of the equipment, staffing levels in a geographic location and customer preferences, and can range from a few days to a few months. Service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer. Revenue from the sale of software products that are not required to deliver the tangible product's essential functionality are accounted for under software revenue recognition rules which require VSOE of fair value to allocate revenue in a multiple-element arrangement. Our arrangements generally do not include any provisions for cancellation, termination, or refunds that would significantly impact recognized revenue. We evaluate the deliverables in our multiple-element arrangements and conclude that they are separate units of accounting if it is determined the delivered item or items have value to the customer on a standalone basis. For arrangements that include a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) has been determined to be probable and substantially in our control. We allocate revenue to each element in our multiple-element arrangements based upon their relative selling prices. We determine the selling price for each deliverable based on a selling price hierarchy. The selling price for a deliverable is based on VSOE if available, TPE if VSOE is not available, or ESP if neither VSOE nor TPE is available. Revenue allocated to each element is then recognized when the basic revenue recognition criteria for that element have been met. We use VSOE of selling price in the selling price allocation in all instances where it exists. VSOE of selling price for products and services is determined when a substantial majority of the selling prices fall within a reasonable range when sold separately. TPE of selling price can be established by evaluating largely interchangeable competitor products or services in standalone sales to similarly situated customers. As our products contain a significant element of proprietary technology and the solution offered differs substantially from that of competitors, it is difficult to obtain the reliable standalone competitive pricing necessary to establish TPE. ESP represents the best estimate of the price at which we would transact a sale if the product or service were sold on a standalone basis. We determine ESP for a product or service by using historical selling prices which reflect multiple factors including, but not limited to, customer type, geography, market conditions, competitive landscape, gross margin objectives and pricing practices. The determination of ESP is made through consultation with and approval by management. We may modify or develop new pricing practices and strategies in the future. As these pricing strategies evolve, changes may occur in ESP. The aforementioned factors may result in a different allocation of revenue to the deliverables in multiple-element arrangements, which may change the pattern and timing of revenue recognition for these elements but will not change the total revenue recognized for the arrangement. Shipping and handling costs. Our shipping and handling costs charged to customers are included in net revenue, and the associated expense is recorded in cost of products for all periods presented. Deferred revenue. Deferred revenue represents the amount that is allocated to undelivered elements in multiple-element arrangements. We limit the revenue recognized to the amount that is not contingent on the future delivery of products or services or meeting other specified performance conditions. In addition, service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer.
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 doubtful accounts, 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 doubtful accounts as of October 31, 2015 and 2014 was not material. We do not have any off-balance-sheet credit exposure related to our customers. Accounts receivable are also recorded net of product returns.
Share-based compensation	Prior to our separation from Agilent, our employees historically participated in Agilent’s various incentive award plans, including employee stock options, restricted stock units and the employee stock purchases made under Agilent’s Employee Stock Purchase Plan ("Agilent's ESPP”) and we participated in Agilent’s share-based compensation plans and recorded share-based compensation expense based on the equity awards granted to our employees. We recorded compensation expense based on expenses for the awards to our employees as well as an allocation of Agilent’s corporate and shared services employee expenses. In 2015 , we accounted for share-based awards made to our employees and directors including employee stock option awards, restricted stock units, employee stock purchases made under Keysight's Employee Stock Purchase Plan ("Keysight's ESPP") and performance share awards under Keysight Technologies, Inc. Long-Term Performance ("Keysight's LTP") Program using the estimated grant date fair value method of accounting. In 2014 and 2013 , we accounted for share-based awards made to our employees and directors including employee stock option awards, restricted stock units, employee stock purchases made under Agilent's ESPP and performance share awards under Agilent Technologies, Inc. Long-Term Performance ("Agilent's LTP") Program using the estimated grant date fair value method of accounting.
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	Our standard warranty term for most of our products from the date of delivery is typically three years, which increased from one year in the second quarter of fiscal 2013. We accrue for standard warranty costs based on historical trends in warranty charges as a percentage of net product revenue. 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 17, "Guarantees." 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.
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 recognizing and measuring 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% 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 at least annually in the fourth quarter, as of September 30, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. In accordance with the authoritative accounting guidance we have the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If we determine this is the case, we are required to perform the two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized. If we determine that it is more-likely-than-not that the fair value of the reporting unit is greater than its carrying amounts, the two-step goodwill impairment test is not required. As defined in the authoritative guidance, a reporting unit is an operating segment, or one level below an operating segment. Historically, we conducted our business in a single operating segment and reporting unit. In fiscal 2014, in conjunction with the planned separation, we implemented changes in our organizational structure which resulted in the formation of two reportable operating segments, which are also our reporting units. In fiscal year 2015, we assessed goodwill impairment by performing a qualitative test for our two reporting units, which consisted of our two segments, Measurement Solutions and Customer Support and Services. Based on the results of our testing, it was determined that it is more-likely-than-not that the fair value of the reporting units are greater than their carrying amounts. There was no impairment of goodwill during the years ended October 31, 2015, 2014 and 2013. Other intangible assets consist primarily of developed technologies, proprietary know-how, trademarks, and customer relationships and are amortized using the straight-line method over estimated useful lives ranging from 6 months to 15 years. No impairments of purchased intangible assets were recorded during the year ended October 31, 2015, 2014 and 2013. 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. 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 (i.e. > 50% chance) 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. Due to cancellation of a specific IPR&D project, we recorded an impairment of $1 million in 2013. There were no impairments in fiscal years 2015 and 2014. In all other instances we used the qualitative test and concluded that it was more-likely-than-not that all other indefinite-lived assets were not impaired.
Advertising	Advertising costs are expensed as incurred
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.
Sales Taxes	Sales taxes collected from customers and remitted to governmental authorities are not included in our revenue.
Investments	Cost method investments consisting of non-marketable equity securities are accounted for at historical cost. Trading securities are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. Investments designated as available-for-sale are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income. The Company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may not be recoverable.
Net income per share	Basic net income per share is computed by dividing net income - the numerator - by the weighted average number of common shares outstanding - the denominator - 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, the tax benefits and shortfalls charged to additional paid-in capital and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options, unamortized share-based compensation expense and tax benefits or shortfalls 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, 2015 , approximately $338 million of our cash and cash equivalents was held outside of the U.S. in our foreign subsidiaries. Under current tax laws, most of the cash could be repatriated to the U.S., but it would be subject to U.S. federal and state income taxes, less applicable foreign tax credits. Our cash and cash equivalents mainly consist of short-term deposits held at major global financial institutions, investments in institutional money market funds, and similar short duration instruments with original maturities of 90 days or less. We continuously monitor the creditworthiness of the financial institutions and institutional money market funds in which we invest our funds. 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 cost or equity method, their carrying value approximates their estimated fair value. The fair value of our long-term debt, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy, was below the carrying value by approximately $8 million as of October 31, 2015 and exceeded the carrying value by approximately $1 million as of October 31, 2014. 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.
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 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. Credit evaluation is performed by an independent team to ensure proper segregation of duties.
Derivative instruments	We are exposed to global foreign currency exchange rate risk in the normal course of business. We enter into foreign exchange hedging contracts, primarily forward contracts and purchased options 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. For option contracts, we exclude time value from the measurement of effectiveness. 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 hedging contracts generally mature within twelve months. In order to manage foreign currency exposures in a few limited jurisdictions we may enter into foreign exchange contracts that do not qualify for hedge accounting. In such circumstances, the local foreign currency exposure is offset by contracts owned by the parent company. 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 their fair value and changes in the fair values are recorded in the income statement in the current period. Derivative instruments are subject to master netting arrangements and qualify for net presentation in the balance sheet. Changes in the fair value of the ineffective portion of derivative instruments are recognized in earnings in the current period. 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 and amortization are removed from our general ledger, and the resulting gain or loss is reflected in the combined and consolidated statement of operations. Buildings and improvements are depreciated over the lesser of their useful lives or the remaining term of the lease and machinery and equipment over three to ten years. We use the straight-line method to depreciate assets.
Leases	We lease buildings, machinery and equipment under operating leases for original terms ranging generally from one to twenty-five years. Certain leases contain renewal options for periods up to ten years.
Capitalized software	We capitalize certain internal and external costs incurred to acquire or create internal use software. Capitalized software is included in property, plant and equipment and is depreciated over three to five years once development is complete.
Impairment of long-lived assets	We continually monitor events and changes in circumstances that could indicate carrying amounts of long-lived assets, including intangible 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 restructuring plan is related to workforce reductions. 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 accounted for within employee compensation and benefits.
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 which approximate to 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 which approximate average exchange rates in effect during each period. Gains or losses from foreign currency re-measurement are included in net income.
Retirement plans and post-retirement benefit plan assumptions	Retirement and post-retirement benefit plan costs are a significant cost of doing business. They represent obligations that will ultimately be settled sometime in the future and therefore are subject to estimation. Pension accounting is intended to reflect the recognition of future benefit costs over the employees' average expected future service to Keysight based on the terms of the plans and investment and funding decisions. To estimate the impact of these future payments and our decisions concerning funding of these obligations, we are required to make assumptions using actuarial concepts within the framework of U.S. 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 portfolio composition. We evaluate these assumptions at least annually.
