Accounting Policies [Abstract]
OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	OVERVIEW, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Overview. Agilent Technologies, Inc. ("we", "Agilent" or the "company"), incorporated in Delaware in May 1999, is a global leader in life sciences, diagnostics and applied chemical markets, providing application focused solutions that include instruments, software, services and consumables for the entire laboratory workflow. Our fiscal year-end is October 31, and our fiscal quarters end on January 31, April 30 and July 31. Unless otherwise stated, these dates refer to our fiscal year and fiscal quarters. Basis of Presentation . We have prepared the accompanying financial data for the three months ended January 31, 2021 and 2020 pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. have been condensed or omitted pursuant to such rules and regulations. The October 31, 2020 condensed balance sheet data was derived from audited financial statements but does not include all the disclosures required in audited financial statements by U.S. GAAP. The accompanying financial data and information should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended October 31, 2020. In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary for a fair statement of our condensed consolidated balance sheet as of January 31, 2021 and October 31, 2020, condensed consolidated statement of comprehensive income (loss) for the three months ended January 31, 2021 and 2020, condensed consolidated statement of operations for the three months ended January 31, 2021 and 2020, condensed consolidated statement of cash flows for the three months ended January 31, 2021 and 2020 and condensed consolidated statement of equity for the three months ended January 31, 2021 and 2020. Use of Estimates. The preparation of condensed consolidated financial statements in accordance with GAAP in the U.S. requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s 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, retirement and post-retirement benefit plan assumptions, valuation of goodwill and purchased intangible assets and accounting for income taxes. Restricted Cash and Restricted Cash Equivalents. Restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. A reconciliation of cash, cash equivalents and restricted cash to the condensed consolidated balance sheet follows: January 31, October 31 2021 2020 (in millions) Cash and cash equivalents $ 1,329 $ 1,441 Restricted cash included in other assets 7 6 Total cash, cash equivalents and restricted cash $ 1,336 $ 1,447 Leases. As of January 31, 2021 and October 31, 2020, operating lease right-of-use assets where we are the lessee were $173 million and $175 million, respectively, and were included within other assets in the accompanying condensed consolidated balance sheet. The associated operating lease liabilities were $176 million and $178 million as of January 31, 2021 and October 31, 2020, respectively, and were included in other accrued liabilities and other long-term liabilities in the accompanying condensed consolidated balance sheet. Variable Interest Entities. We make a determination upon entering into an arrangement whether an entity in which we have made an investment is considered a Variable Interest Entity (“VIE”). We evaluate our investments in privately held companies on an ongoing basis. We have determined that as of January 31, 2021 and October 31, 2020, there were no VIEs required to be consolidated in our consolidated financial statements because we do not have a controlling financial interest in any of the VIEs in which we have invested nor are we the primary beneficiary. We account for these investments under either the equity method or as equity investments without readily determinable fair value, depending on the circumstances. We periodically reassess whether we are the primary beneficiary of a VIE. The reassessment process considers whether we have acquired the power to direct the most significant activities of the VIE through changes in governing documents or other circumstances. We also reconsider whether entities previously determined not to be VIEs have become VIEs, based on changes in facts and circumstances including changes in contractual arrangements and capital structure. As of January 31, 2021 and October 31, 2020, the total carrying value of investments and loans in privately held companies considered as VIEs was $78 million and $67 million respectively. The maximum exposure is equal to the carrying value because we do not have future funding commitments. The investments are included on the long-term investments line and the loans on the other current assets and other assets lines (depending upon tenure of loan) on the condensed consolidated balance sheet. Fair Value of Financial Instruments. The carrying values of certain of our financial instruments including cash and cash equivalents, accounts receivable, accounts payable, accrued compensation and other accrued liabilities approximate fair value because of their short maturities. The fair value of long-term equity investments which are readily determinable, and which are not accounted under the equity method are reported at fair value using quoted market prices for those securities when available with gains and losses included in net income. The fair value of long-term equity investments which are not readily determinable, and which are not accounted under the equity method are reported at cost with adjustments for observable changes in prices or impairments included in net income. The fair value of our senior notes, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy exceeds the carrying value by approximately $162 million as of January 31, 2021 and October 31, 2020. The fair value is greater than carrying value primarily due to decreased market interest rates. 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 9, "Fair Value Measurements" for additional information on the fair value of financial instruments.

NEW ACCOUNTING PRONOUNCEMENTS (

NEW ACCOUNTING PRONOUNCEMENTS (Notes)	3 Months Ended
	Jan. 31, 2021
Accounting Policies [Abstract]
NEW ACCOUNTING PRONOUNCEMENTS	NEW ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements In June 2016, the FASB issued new guidance to require a financial asset measured at amortized cost basis, such as accounts receivable, to be presented at the net amount expected to be collected based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. During 2018 and 2019, the FASB issued additional guidance and clarification. On November 1, 2020, we adopted this guidance which did not have a material impact on our condensed consolidated financial statements. In January 2017, the FASB issued new guidance that simplifies the measurement of goodwill impairment by eliminating the Step 2 requirement that an entity compute the implied fair value of goodwill based on the fair values of its assets and liabilities to measure impairment. Instead, goodwill impairment will be measured as the difference between the fair value of the reporting unit and the carrying value of the reporting unit. The standard also clarifies the treatment of the income tax effect of tax deductible goodwill when measuring goodwill impairment loss. On November 1, 2020, we adopted this guidance which did not have a material impact on our condensed consolidated financial statements. In August 2018, the Financial Accounting Standards Board ("FASB") issued updates to improve the disclosure requirements for fair value measurements in Topic 820, Fair Value Measurement which eliminates certain disclosure requirements and modifies others. On November 1, 2020, we adopted these amendments which did not have a material impact on our consolidated financial statements and disclosures. See Note 9, "Fair Value Measurements" for additional information on the fair value of financial instruments disclosures. In December 2019, the FASB issued new guidance to simplify the accounting for income taxes. This guidance eliminates certain exceptions to existing guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The guidance also improves consistent application by clarifying and amending existing guidance related to aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step up in the tax basis of goodwill. On November 1, 2020, we early adopted this guidance which did not have a material impact on our condensed consolidated financial statements and disclosures. In March 2020, the FASB issued an update for facilitation of the effects of reference rate reform on financial reporting. This update provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in the guidance provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply to contracts, hedging relationships, and other transactions that reference London Inter-bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. When elected, the optional expedients for contract modifications are applied consistently for all eligible contracts or eligible transactions within the relevant Topic or Industry Subtopic in the FASB's Accounting Standards Codification. The guidance was effective upon issuance and may generally be applied through December 31, 2022 to any new or amended contracts, hedging relationships, and other transactions that reference LIBOR. In January 2021, the FASB issued an update that provides supplemental guidance and clarification of the reference rate reform. The update provides additional optional guidance on the transition from LIBOR to include derivative instruments that use an interest rate for margining, discounting or contract price alignment. The standard will ease, if warranted, the requirements for accounting for the future effects of the rate reform. An entity may elect to apply the amendments prospectively through December 31, 2022. We continue to monitor the impact that the discontinuance of LIBOR or another reference rate will have on our contracts, hedging relationships and other transactions. Accounting Pronouncements Not Yet Adopted There were no additions to the new accounting pronouncements not yet adopted as described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2020. 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 condensed consolidated financial statements upon adoption.

Revenue by end market is determined by the market indicator of the customer and by customer type. Instrumentation revenue includes sales from instruments, remarketed instruments and third-party products. Non-instrumentation and other revenue include sales from contract and per incident services, our companion diagnostics and our nucleic acid solutions businesses as well as sales from spare parts, consumables, reagents, vacuum pumps, subscriptions, software licenses and associated services. Contract Balances Contract Assets Contract assets (unbilled accounts receivable) primarily relate to the company's right to consideration for work completed but not billed at the reporting date. The unbilled receivables are reclassified to trade receivables when billed to customers. Contract assets are generally classified as current assets and are included in "Accounts receivable, net" in the condensed consolidated balance sheet. The balances of contract assets as of January 31, 2021 and October 31, 2020 were $154 million and $153 million, respectively. The increase in unbilled receivables during the three months ended January 31, 2021 is a result of recognition of revenue upon the transfer of the control to the customer. Contract Liabilities The following table provides information about contract liabilities (deferred revenue) and the significant changes in the balances during the three months ended January 31, 2021: Contract (in millions) Ending balance as of October 31, 2020 $ 446 Net revenue deferred in the period 197 Revenue recognized that was included in the contract liability balance at the beginning of the period (186) Change in deferrals from customer cash advances, net of revenue recognized 20 Currency translation and other adjustments 8 Ending balance as of January 31, 2021 $ 485 During the three months ended January 31, 2020 revenue recognized that was included in the contract liability balance at October 31, 2019 was $142 million. Contract liabilities primarily relate to multiple element arrangements for which billing has occurred but transfer of control of all elements to the customer has either partially or not occurred at the balance sheet date. This includes cash received from customers for products and related installation and services in advance of the transfer of control. Contract liabilities are classified as either current in deferred revenue or long-term in other long-term liabilities in the condensed consolidated balance sheet based on the timing of when we expect to complete our performance obligation. Contract Costs Incremental costs of obtaining a contract with a customer are recognized as an asset if we expect the benefit of those costs to be longer than one year. We have determined that certain sales incentive programs meet the requirements to be capitalized. The change in total capitalized costs to obtain a contract was immaterial during the three months ended January 31, 2021 and was included in other current and long-term assets on the condensed consolidated balance sheet. We have applied the practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. These costs include the company's internal sales force compensation program, as we have determined that annual compensation is commensurate with annual sales activities. Transaction Price Allocated to the Remaining Performance Obligations We have applied the practical expedient in ASC 606-10-50-14 and have not disclosed information about transaction price allocated to remaining performance obligations that have original expected durations of one year or less.

SHARE-BASED COMPENSATION (Notes

SHARE-BASED COMPENSATION (Notes)	3 Months Ended
	Jan. 31, 2021
Share-based Payment Arrangement, Noncash Expense [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION We account 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 options, restricted stock units, employee stock purchases made under our employee stock purchase plan and performance share awards granted to selected members of our senior management under the long-term performance plan (“LTPP”) based on estimated fair values. We have two LTPP performance stock award programs, which are administered under the 2018 Stock Plan, for our executive officers and other key employees. Participants in our LTPP Total Stockholders’ Return (“TSR”) and LTPP Earnings Per Share (“EPS”) programs are entitled to receive shares of the company's stock after the end of a three-year period, if specified performance targets for the programs are met. The LTPP-TSR awards are generally designed to meet the criteria of a performance award with the performance metrics and peer group comparison based on the TSR set at the beginning of the performance period. The LTPP-EPS awards are based on the company’s EPS performance over a three-year period. The performance targets for the LTPP-EPS for year 2 and year 3 of the performance period are set in the first quarter of year 2 and year 3, respectively. All LTPP awards are subject to a one-year post-vest holding period. The final LTPP award may vary from 0 percent to 200 percent of the target award. We consider the dilutive impact of these programs in our diluted net income per share calculation only to the extent that the performance conditions are expected to be met. 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. In fiscal year 2021, we resumed granting stock options. Stock options granted under the 2018 Stock Plan may be either "incentive stock options", as defined in Section 422 of the Internal Revenue Code, or non-statutory. Options generally vest at a rate of 25 percent per year over a period of four years from the date of grant with a maximum contractual term of ten years. The exercise price for stock options is generally not less than 100 percent of the fair market value of our common stock on the date the stock award is granted. We issue new shares of common stock when employee stock options are exercised. The impact on our results for share-based compensation was as follows: Three Months Ended January 31, 2021 2020 (in millions) Cost of products and services $ 9 $ 6 Research and development 4 3 Selling, general and administrative 27 18 Total share-based compensation expense $ 40 $ 27 At January 31, 2021 and October 31, 2020, there was no share-based compensation capitalized within inventory. The following assumptions were used to estimate the fair value of awards granted. Three Months Ended January 31, 2021 2020 Stock Option Plans: Weighted average risk-free interest rate 0.2% — Dividend yield 0.7% — Weighted average volatility 26% — Expected life 5.5 years — LTPP: Volatility of Agilent shares 30% 23% Volatility of selected peer-company shares 24%-57% 15%-44% Pair-wise correlation with selected peers 45% 29% Post-vest holding restriction discount for all executive awards 6.8% 5.3% The fair value of share-based awards for our employee stock option awards was estimated using the Black-Scholes option pricing model. Shares granted under the LTPP (TSR) were valued using a Monte Carlo simulation model. The Monte Carlo simulation fair value model requires the use of highly subjective and complex assumptions, including the price volatility of the underlying stock. For the volatility of our LTPP (TSR) grants, we used our own historical stock price volatility. The ESPP allows eligible employees to purchase shares of our common stock at 85 percent of the price at purchase and uses the purchase date to establish the fair market value. We use historical volatility to estimate the expected stock price volatility assumption for employee stock option awards. In reaching the conclusion, we have considered many factors including the extent to which our options are currently traded and our ability to find traded options in the current market with similar terms and prices to the options we are valuing. In estimating the expected life of our options granted we considered the historical option exercise behavior of our executives, which we believe is representative of future behavior. The estimated fair value of restricted stock units and LTPP (EPS) awards is determined based on the market price of our common stock on the date of grant adjusted for expected dividend yield. The compensation cost for LTPP (EPS) reflects the cost of awards that are probable to vest at the end of the performance period.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three months ended January 31, 2021, our income tax expense was $24 million with an effective tax rate of 7.7 percent. For the three months ended January 31, 2021, our effective tax rate and the resulting provision for income taxes were impacted by the expiration of various foreign statutes of limitations which resulted in the recognition of previously unrecognized tax benefits of $16 million. The income taxes for the three months ended January 31, 2021 also include the excess tax benefits from stock-based compensation of $20 million. Our calculation of income tax expense for the three months ended January 31, 2021 is dependent in part on forecasts of full year results. The impact of the COVID-19 outbreak on the economic environment is uncertain and may change these forecasts, which could impact tax expense. For the three months ended January 31, 2020, our income tax expense was $22 million with an effective tax rate of 10.0 percent. For the three months ended January 31, 2020, our effective tax rate and the resulting provision for income taxes were impacted by a discrete benefit of $13 million related to the excess tax benefits from stock compensation. In the U.S., tax years remain open back to the year 2017 for federal income tax purposes and for significant states. In other major jurisdictions where the company conducts business, the tax years generally remain open back to the year 2009. With these jurisdictions and the U.S., it is reasonably possible there could be significant changes to our unrecognized tax benefits in the next twelve months due to either the expiration of a statute of limitation or a tax audit settlement which will be partially offset by an anticipated tax liability related to unremitted foreign earnings, where applicable. Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, management is unable to estimate the range of possible changes to the balance of our unrecognized tax benefits.

NET INCOME PER SHARE	NET INCOME PER SHARE The following is a reconciliation of the numerator and denominator of the basic and diluted net income per share computations for the periods presented below: Three Months Ended January 31, 2021 2020 (in millions) Numerator: Net income $ 288 $ 197 Denominator: Basic weighted-average shares 306 310 Potential common shares— stock options and other employee stock plans 3 3 Diluted weighted-average shares 309 313 The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options and unamortized share-based compensation expense 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. 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. In addition, we exclude from the calculation of diluted earnings per share stock options, ESPP, LTPP and restricted stock awards whose combined exercise price and unamortized fair value were greater than the average market price of our common stock because their effect would also be anti-dilutive.

During the three months ended January 31, 2021, other intangible assets in total increased $1 million due to the impact of foreign currency translation. In general, for United States federal tax purposes, goodwill from asset purchases is deductible; however, any goodwill created as part of a stock acquisition is not deductible. Each quarter we review the events and circumstances to determine if impairment of indefinite-lived intangible assets and goodwill is indicated. During the three months ended January 31, 2021 and 2020 we did not identify any triggering events or circumstances, including impacts due to COVID-19, which would indicate an impairment of goodwill or indefinite-lived intangible assets. Amortization expense of intangible assets was $45 million and $48 million for the three months ended January 31, 2021 and 2020, respectively. Future amortization expense related to existing finite-lived purchased intangible assets for the remainder of fiscal year 2021 and for each of the next five fiscal years and thereafter is estimated below: Estimated future amortization expense: (in millions) Remainder of 2021 $ 129 2022 $ 152 2023 $ 109 2024 $ 88 2025 $ 70 2026 $ 40 Thereafter $ 188

FAIR VALUE MEASUREMENTS (Notes)

FAIR VALUE MEASUREMENTS (Notes)	3 Months Ended

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 January 31, 2021 were as follows: Fair Value Measurement at January 31, 2021 Using January 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) $ 449 $ 449 $ — $ — Derivative instruments (foreign exchange contracts) 8 — 8 — Long-term Trading securities 31 31 — — Other investments 28 — 28 — Total assets measured at fair value $ 516 $ 480 $ 36 $ — Liabilities: Short-term Derivative instruments (foreign exchange contracts) $ 17 $ — $ 17 $ — Long-term Deferred compensation liability 31 — 31 — Total liabilities measured at fair value $ 48 $ — $ 48 $ — Financial assets and liabilities measured at fair value on a recurring basis as of October 31, 2020 were as follows: Fair Value Measurement at October 31, 2020 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) Assets: Short-term Cash equivalents (money market funds) $ 740 $ 740 $ — $ — Derivative instruments (foreign exchange contracts) 2 — 2 — Long-term Trading securities 30 30 — — Other investments 25 — 25 — Total assets measured at fair value $ 797 $ 770 $ 27 $ — Liabilities: Short-term Derivative instruments (foreign exchange contracts) $ 17 $ — $ 17 $ — Long-term Deferred compensation liability 30 — 30 — Total liabilities measured at fair value $ 47 $ — $ 47 $ — Our money market funds and trading securities 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. Other investments represent shares we own in a special fund that targets underlying investments of approximately 40 percent in debt securities and 60 percent in equity securities. It has been classified as level 2 because, although the shares of the fund are not traded on any active stock exchange, each of the individual underlying securities are or can be derived from and hence we have a readily determinable value for the underlying securities, from which we are able to determine the fair market value for the special fund itself. Trading securities, which is comprised of mutual funds, bonds and other similar instruments, other investments and deferred compensation liability are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in net income. Certain derivative instruments are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income (loss) within stockholders' equity. Realized gains and losses from the sale of these instruments are recorded in net income. Impairment of Investments. There were no impairments of investments for the three months ended January 31, 2021 and 2020. Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis For the three months ended January 31, 2021 and 2020, there were no impairments of long-lived assets held and used. For the three months ended January 31, 2021 and 2020, there were no impairments of long-lived assets held for sale. For the three months ended January 31, 2021 and 2020, there were no impairments of non-marketable securities. For the three months ended January 31, 2021 and 2020, an unrealized gain of zero and $16 million, respectively, was included in net income as an adjustment to the carrying value of non-marketable equity securities without readily determinable fair value based on an observable market transaction. As of January 31, 2021 and October 31, 2020, the carrying amount of non-marketable equity securities without readily determinable fair values was $105 million and $103 million, respectively. Fair values for the non-marketable securities included in long-term investments on the condensed consolidated balance sheet were measured using Level 3 inputs because they are primarily equity stock issued by private companies without quoted market prices. To estimate the fair value of our non-marketable securities, we use the measurement alternative to record these investments at cost and adjust for impairments and observable price changes (orderly transactions for the identical or a similar security from the same issuer) as and when they occur.

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 our 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. 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 and are assessed for effectiveness against the underlying exposure every reporting period. For open contracts as of January 31, 2021, changes in the time value of the foreign exchange contract are excluded from the assessment of hedge effectiveness and are recognized in cost of sales over the life of the foreign exchange contract. The changes in fair value of the effective portion of the derivative instrument are recognized in accumulated other comprehensive income (loss). Amounts associated with cash flow hedges are reclassified to cost of sales in the condensed 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 (loss) 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 other income (expense), net in the condensed 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 cost of sales over the life of the option contract. For the three months ended January 31, 2021 and 2020, ineffectiveness and gains and losses recognized in other income (expense), net due to de-designation of cash flow hedge contracts were not significant. In July 2012, Agilent executed treasury lock agreements for $400 million in connection with future interest payments to be made on our 2022 senior notes issued on September 13, 2012. We designated the treasury lock as a cash flow hedge. The treasury lock contracts were terminated on September 10, 2012, and we recognized a deferred gain in accumulated other comprehensive income (loss) which is being amortized to interest expense over the life of the 2022 senior notes. On January 21, 2021 we redeemed $100 million of the $400 million aggregate principal amount of our 2022 senior notes and recognized a portion of the deferred gain on the terminated treasury lock related to the redeemed portion of the notes to other income (expense), net. For more information see Note 14, "Long-Term Debt". The remaining gain to be amortized related to the treasury lock agreements at January 31, 2021 was less than $1 million. In February 2016, Agilent executed three forward-starting pay fixed/receive variable interest rate swaps for the notional amount of $300 million in connection with future interest payments to be made on our 2026 senior notes issued on September 15, 2016. These derivative instruments were designated and qualified as cash flow hedges under the criteria prescribed in the authoritative guidance. The swap arrangements were terminated on September 15, 2016 with a payment of $10 million, and we recognized this as a deferred loss in accumulated other comprehensive income (loss) which is being amortized to interest expense over the life of the 2026 senior notes. The remaining loss to be amortized related to the interest rate swap agreements at January 31, 2021 was $5 million. In August 2019, Agilent executed treasury lock agreements for $250 million in connection with future interest payments to be made on our 2029 senior notes issued on September 16, 2019. We designated the treasury lock as a cash flow hedge. The treasury lock contracts were terminated on September 6, 2019, and we recognized a deferred loss of $6 million in accumulated other comprehensive income (loss) which is being amortized to interest expense over the life of the 2029 senior notes. The remaining loss to be amortized related to the treasury lock agreements at January 31, 2021 was $5 million. Net Investment Hedges Starting in 2020, we entered into foreign exchange contracts to hedge net investments in foreign operations to mitigate the risk of adverse movements in exchange rates. These foreign exchange contracts are carried at fair value and are designated and qualify as net investment hedges under the criteria prescribed in the authoritative guidance. Changes in fair value of the effective portion of the derivative instrument are recognized in accumulated other comprehensive income (loss) and are assessed for effectiveness against the underlying exposure every reporting period. If the company’s net investment changes during the year, the hedge relationship will be assessed and de-designated if the hedge notional amount is outside of prescribed tolerance with a gain/loss reclassified from other comprehensive income (loss) to other income (expense) in the current period. As of January 31, 2021, we have 3 open forward contracts to sell euros to buy USD maturing in the second quarter of fiscal year 2021, and these are designated as a net investment hedge of the U.S. parent's interest in foreign subsidiaries denominated in euro functional currency. In the three months ended January 31, 2021, the change in fair value of the net investment hedge resulted in a net loss of $4 million recognized in accumulated other comprehensive income. For the three months ended January 31, 2021, ineffectiveness and the resultant effect of any gains or losses recognized in other income (expense) due to de-designation of the hedge contracts were 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 instruments are recognized in other income (expense), net in the condensed consolidated statement of operations, in the current period, along with the offsetting foreign currency gain or loss on the underlying assets or liabilities. Our use of derivative instruments exposes us to credit risk to the extent that the counterparties may be unable to meet the terms of the agreement. We do, however, seek to mitigate such risks by limiting our counterparties to major financial institutions which are selected based on their credit ratings and other factors. We have established policies and procedures for mitigating credit risk that include establishing counterparty credit limits, monitoring credit exposures, and continually assessing the creditworthiness of counterparties. 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 January 31, 2021, was $13 million. The credit-risk-related contingent features underlying these agreements had not been triggered as of January 31, 2021. There were 270 foreign exchange forward contracts open as of January 31, 2021 and designated as cash flow hedges. There were 209 foreign exchange forward contracts open as of January 31, 2021 and not designated as hedging instruments. There were 3 foreign exchange forward contracts open as of January 31, 2021 and designated as a net investment hedge.

WARRANTIES AND CONTINGENCIES	WARRANTIES AND CONTINGENCIES Warranties We accrue for standard warranty costs based on historical trends in actual warranty charges over the past 12 months. The accrual is reviewed regularly and periodically adjusted to reflect changes in warranty cost over the period. The standard warranty accrual balances are held in other accrued and other long-term liabilities on our condensed consolidated balance sheet. Our standard warranty terms typically extend to one year from the date of delivery, depending on the product. A summary of the standard warranty accrual activity is shown in the table below: Three Months Ended January 31, 2021 2020 (in millions) Standard warranty accrual, beginning balance $ 32 $ 32 Accruals for warranties including change in estimates 15 12 Settlements made during the period (15) (14) Standard warranty accrual, ending balance $ 32 $ 30 Accruals for warranties due within one year $ 31 $ 30 Accruals for warranties due after one year 1 — Standard warranty accrual, ending balance $ 32 $ 30 Bank Guarantees Guarantees consist primarily of outstanding standby letters of credit and bank guarantees and were approximately $43 million as of January 31, 2021 and as of October 31, 2020. A standby letter of credit is a guarantee of payment issued by a bank on behalf of us that is used as payment of last resort should we fail to fulfill a contractual commitment with a third party. A bank guarantee is a promise from a bank or other lending institution that if we default on a loan, the bank will cover the loss. Contingencies We are involved in lawsuits, claims, investigations and proceedings, including, but not limited to, intellectual property, commercial, real estate, environmental and employment matters, which arise in the ordinary course of business. There are no matters pending that we currently believe are reasonably possible of having a material impact to our business, condensed consolidated financial condition, results of operations or cash flows.

Short-term Debt [Abstract]
SHORT-TERM DEBT	SHORT-TERM DEBT Credit Facilities On March 13, 2019, we entered into a credit agreement with a group of financial institutions which provided for a $1 billion five-year unsecured credit facility that will expire on March 13, 2024. As of January 31, 2021, we had no borrowings outstanding under the credit facility. On August 7, 2019, we entered into an amendment to the credit agreement, which provided for a $500 million short-term loan facility that was used in full to complete the BioTek acquisition and which was repaid in full as of January 31, 2021. On October 21, 2019, we entered into a second amendment to the credit agreement, which refreshed the amount available for additional incremental term loan facilities under the credit agreement to permit additional incremental facilities of up to $500 million. We had no borrowings under the additional incremental loan facilities as of January 31, 2021. On April 17, 2020, we entered into a third amendment to the credit agreement which provided the company with the option to request the consent of the applicable class of lenders to extend the maturity date of revolving borrowings and swingline loans for an additional period of one year and of incremental term loans for an additional period of up to 364 days. We were in compliance with the covenants for the credit facility during the three months ended January 31, 2021. In May 2020, we established a U.S. commercial paper program, under which the company may issue and sell unsecured, short-term promissory notes in the aggregate principal amount not to exceed $1.0 billion with up to 397-day maturities. At any point in time, the company intends to maintain available commitments under its revolving credit facility in an amount at least equal to the amount of the commercial paper notes outstanding. Amounts available under the program may be borrowed, repaid and re-borrowed from time to time. The proceeds from issuances under the program may be used for general corporate purposes. As of January 31, 2021

The 2022 senior notes were issued at 99.80% of their principal amount. The notes will mature on October 1, 2022, and bear interest at a fixed rate of 3.20% per annum. The interest is payable semi-annually on April 1st and October 1st of each year and payments commenced on April 1, 2013. On January 21, 2021, we redeemed $100 million of the $400 million outstanding aggregate principal amount of our 2022 senior notes due October 1, 2022. The redemption price of approximately $105 million is computed in accordance with the terms of the 2022 senior notes as the present value of the remaining scheduled payments of principal and unpaid interest on the notes being redeemed. In addition, $1 million of accrued interest, up to but not including the redemption date, was paid. The make-whole premium less partial amortization of previously deferred interest rate swap gain together with the amortization of debt issuance costs and discount was recorded in other income (expense), net in the condensed consolidated statement of operations.

Stockholders' Equity Note [Abstract]
STOCKHOLDERS EQUITY	STOCKHOLDERS' EQUITY Stock Repurchase Program On November 19, 2018 we announced that our board of directors had approved a share repurchase program (the "2019 repurchase program") designed, among other things, to reduce or eliminate dilution resulting from issuance of stock under the company's employee equity incentive programs. The 2019 repurchase program authorizes the purchase of up to $1.75 billion of our common stock at the company's discretion and has no fixed termination date. The 2019 repurchase program does not require the company to acquire a specific number of shares and may be suspended, amended or discontinued at any time. Effective February 18, 2021, the 2019 repurchase program was terminated and replaced by the new share repurchase program. The remaining authorization under the 2019 repurchase plan of $193 million expired on February 18, 2021. During the three months ended January 31, 2021, we repurchased and retired 2,885,152 shares for $344 million under this authorization. During the three months ended January 31, 2020, we repurchased and retired 725,827 shares for $60 million under this authorization. As of January 31, 2021, we had remaining authorization to repurchase up to approximately $214 million of our common stock under this program. On February 16, 2021 we announced that our board of directors had approved a new share repurchase program (the "2021 repurchase program") designed, among other things, to reduce or eliminate dilution resulting from issuance of stock under the company's employee equity incentive programs. The 2021 repurchase program authorizes the purchase of up to $2.0 billion of our common stock at the company's discretion and has no fixed termination date. The 2021 repurchase program which became effective on February 18, 2021, replaced and terminated the 2019 repurchase program on that date. The 2021 repurchase program does not require the company to acquire a specific number of shares and may be suspended, amended or discontinued at any time. Cash Dividends on Shares of Common Stock During the three months ended January 31, 2021, we paid cash dividends of $0.194 per common share or $59 million on the company's common stock. During the three months ended January 31, 2020, we paid cash dividends of $0.180 per common share or $56 million on the company's common stock.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Description of segments. We are a global leader in life sciences, diagnostics and applied chemical markets, providing application focused solutions that include instruments, software, services and consumables for the entire laboratory workflow. Agilent has three business segments comprised of the life sciences and applied markets business, diagnostics and genomics business and the Agilent CrossLab business each of which comprises a reportable segment. The three 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 three reportable segments is as follows: Our life sciences and applied markets business provides application-focused solutions that include instruments and software that enable customers to identify, quantify and analyze the physical and biological properties of substances and products, as well as enable customers in the clinical and life sciences research areas to interrogate samples at the molecular and cellular level. Key product categories include: liquid chromatography ("LC") systems and components; liquid chromatography mass spectrometry ("LCMS") systems; gas chromatography ("GC") systems and components; gas chromatography mass spectrometry ("GCMS") systems; inductively coupled plasma mass spectrometry ("ICP-MS") instruments; atomic absorption ("AA") instruments; microwave plasma-atomic emission spectrometry ("MP-AES") instruments; inductively coupled plasma optical emission spectrometry ("ICP-OES") instruments; raman spectroscopy; cell analysis plate based assays; flow cytometer; real-time cell analyzer; cell imaging systems; microplate reader; laboratory software for sample tracking; information management and analytics; laboratory automation and robotic systems; dissolution testing; vacuum pumps and measurement technologies. Our diagnostics and genomics business is comprised of six areas of activity providing active pharmaceutical ingredients ("APIs") for oligo-based therapeutics as well as solutions that include reagents, instruments, software and consumables, which enable customers in the clinical and life sciences research areas to interrogate samples at the cellular and molecular level. First, our genomics business includes arrays for DNA mutation detection, genotyping, gene copy number determination, identification of gene rearrangements, DNA methylation profiling, gene expression profiling, as well as next generation sequencing ("NGS") target enrichment and genetic data management and interpretation support software. This business also includes solutions that enable clinical labs to identify DNA variants associated with genetic disease and help direct cancer therapy. Second, our nucleic acid solutions business provides equipment and expertise focused on production of synthesized oligonucleotides under pharmaceutical good manufacturing practices ("GMP") conditions for use as API in an emerging class of drugs that utilize nucleic acid molecules for disease therapy. Third, our pathology solutions business is focused on product offerings for cancer diagnostics and anatomic pathology workflows. The broad portfolio of offerings includes immunohistochemistry ("IHC"), in situ hybridization ("ISH"), hematoxylin and eosin ("H&E") staining and special staining. Fourth, we also collaborate with a number of major pharmaceutical companies to develop new potential pharmacodiagnostics, also known as companion diagnostics, which may be used to identify patients most likely to benefit from a specific targeted therapy. Fifth, the reagent partnership business is a provider of reagents used for turbidimetry and flow cytometry. Finally, our biomolecular analysis business provides complete workflow solutions, including instruments, consumables and software, for quality control analysis of nucleic acid samples. Samples are analyzed using quantitative and qualitative techniques to ensure accuracy in further genomics analysis techniques utilized in clinical and life science research applications. The Agilent CrossLab business spans the entire lab with its extensive consumables and services portfolio, which is designed to improve customer outcomes. Most of the portfolio is vendor neutral, meaning Agilent can serve and supply customers regardless of their instrument purchase choices. Solutions range from chemistries and supplies to services and software helping to connect the entire lab. Key product categories in consumables include GC and LC columns, sample preparation products, custom chemistries, and a large selection of laboratory instrument supplies. Services include startup, operational, training and compliance support, software as a service, as well as asset management and consultative services that help increase customer productivity. Custom service and consumable bundles are tailored to meet the specific application needs of various industries and to keep instruments fully operational and compliant with the respective industry requirements. 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 legal, accounting, tax, facilities, insurance services, information technology services, treasury, order administration, other corporate infrastructure expenses and costs of centralized research and development. 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. In addition, we do not allocate amortization of acquisition-related intangible assets, transformational initiatives expenses, acquisition and integration costs and certain other charges to the operating margin for each segment because management does not include this information in its measurement of the performance of the operating segments. Transformational initiatives include expenses associated with targeted cost reduction activities such as manufacturing transfers, site consolidations, legal entity and other business reorganizations and in-sourcing or outsourcing of activities. The following tables reflect the results of our reportable segments under our management reporting system. The performance of each segment is measured based on several metrics, including segment 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 items such as transformational initiatives, acquisition and integration costs, amortization of intangible assets related to business combinations, interest income, interest expense and other items as noted in the reconciliations below: Three Months Ended January 31, 2021 2020 (in millions) Net Revenue: Life Sciences and Applied Markets $ 722 $ 638 Diagnostics and Genomics 294 249 Agilent CrossLab 532 470 Total net revenue $ 1,548 $ 1,357 Segment Income From Operations: Life Sciences and Applied Markets $ 199 $ 158 Diagnostics and Genomics 55 34 Agilent CrossLab 142 119 Total segment income from operations $ 396 $ 311 The following table reconciles segment income from operations to Agilent’s total enterprise income before taxes: Three Months Ended January 31, 2021 2020 (in millions) Total segment income from operations $ 396 $ 311 Transformational initiatives (11) (13) Amortization of intangible assets related to business combinations (44) (48) Acquisition and integration costs (9) (13) Other (1) (4) (22) Interest income — 3 Interest expense (19) (20) Other income (expense), net 3 21 Income before taxes, as reported $ 312 $ 219 (1) For the three months ended January 31, 2020, the other category primarily includes the legal costs related to a claim we pursued against Twist Bioscience Corporation in addition to other miscellaneous adjustments. The following table reflects segment assets under our management reporting system. Segment assets include allocations of corporate assets, goodwill, net other intangibles and other assets. Unallocated assets primarily consist of cash, cash equivalents, the valuation allowance relating to deferred tax assets and other assets.

Accounting Policies [Abstract]
Overview and Basis of Presentation	Overview. Agilent Technologies, Inc. ("we", "Agilent" or the "company"), incorporated in Delaware in May 1999, is a global leader in life sciences, diagnostics and applied chemical markets, providing application focused solutions that include instruments, software, services and consumables for the entire laboratory workflow. Our fiscal year-end is October 31, and our fiscal quarters end on January 31, April 30 and July 31. Unless otherwise stated, these dates refer to our fiscal year and fiscal quarters. Basis of Presentation . We have prepared the accompanying financial data for the three months ended January 31, 2021 and 2020 pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. have been condensed or omitted pursuant to such rules and regulations. The October 31, 2020 condensed balance sheet data was derived from audited financial statements but does not include all the disclosures required in audited financial statements by U.S. GAAP. The accompanying financial data and information should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended October 31, 2020. In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary for a fair statement of our condensed consolidated balance sheet as of January 31, 2021 and October 31, 2020, condensed consolidated statement of comprehensive income (loss) for the three months ended January 31, 2021 and 2020, condensed consolidated statement of operations for the three months ended January 31, 2021 and 2020, condensed consolidated statement of cash flows for the three months ended January 31, 2021 and 2020 and condensed consolidated statement of equity for the three months ended January 31, 2021 and 2020.
Use of Estimates	Use of Estimates. The preparation of condensed consolidated financial statements in accordance with GAAP in the U.S. requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s 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, retirement and post-retirement benefit plan assumptions, valuation of goodwill and purchased intangible assets and accounting for income taxes.
Restricted Cash and Restricted Cash Equivalents	Restricted Cash and Restricted Cash Equivalents. Restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. A reconciliation of cash, cash equivalents and restricted cash to the condensed consolidated balance sheet follows: January 31, October 31 2021 2020 (in millions) Cash and cash equivalents $ 1,329 $ 1,441 Restricted cash included in other assets 7 6 Total cash, cash equivalents and restricted cash $ 1,336 $ 1,447
Leases	Leases. As of January 31, 2021 and October 31, 2020, operating lease right-of-use assets where we are the lessee were $173 million and $175 million, respectively, and were included within other assets in the accompanying condensed consolidated balance sheet. The associated operating lease liabilities were $176 million and $178 million as of January 31, 2021 and October 31, 2020, respectively, and were included in other accrued liabilities and other long-term liabilities in the accompanying condensed consolidated balance sheet.
Variable Interest Entity	Variable Interest Entities. We make a determination upon entering into an arrangement whether an entity in which we have made an investment is considered a Variable Interest Entity (“VIE”). We evaluate our investments in privately held companies on an ongoing basis. We have determined that as of January 31, 2021 and October 31, 2020, there were no VIEs required to be consolidated in our consolidated financial statements because we do not have a controlling financial interest in any of the VIEs in which we have invested nor are we the primary beneficiary. We account for these investments under either the equity method or as equity investments without readily determinable fair value, depending on the circumstances. We periodically reassess whether we are the primary beneficiary of a VIE. The reassessment process considers whether we have acquired the power to direct the most significant activities of the VIE through changes in governing documents or other circumstances. We also reconsider whether entities previously determined not to be VIEs have become VIEs, based on changes in facts and circumstances including changes in contractual arrangements and capital structure. As of January 31, 2021 and October 31, 2020, the total carrying value of investments and loans in privately held companies considered as VIEs was $78 million and $67 million respectively. The maximum exposure is equal to the carrying value because we do not have future funding commitments. The investments are included on the long-term investments line and the loans on the other current assets and other assets lines (depending upon tenure of loan) on the condensed consolidated balance sheet.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. The carrying values of certain of our financial instruments including cash and cash equivalents, accounts receivable, accounts payable, accrued compensation and other accrued liabilities approximate fair value because of their short maturities. The fair value of long-term equity investments which are readily determinable, and which are not accounted under the equity method are reported at fair value using quoted market prices for those securities when available with gains and losses included in net income. The fair value of long-term equity investments which are not readily determinable, and which are not accounted under the equity method are reported at cost with adjustments for observable changes in prices or impairments included in net income. The fair value of our senior notes, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy exceeds the carrying value by approximately $162 million as of January 31, 2021 and October 31, 2020. The fair value is greater than carrying value primarily due to decreased market interest rates. 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 9, "Fair Value Measurements" for additional information on the fair value of financial instruments.
