Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying Consolidated Financial Statements of HP and its wholly-owned subsidiaries are prepared in conformity with U.S. GAAP. Principles of Consolidation The Consolidated Financial Statements include the accounts of HP and its subsidiaries and affiliates in which HP has a controlling financial interest or is the primary beneficiary. All intercompany balances and transactions have been eliminated. Reclassifications Effective at the beginning of its first quarter of fiscal year 2019, HP implemented an organizational change to align its business unit financial reporting more closely with its current business structure. HP reflected this change to its business unit information in prior reporting periods on an as-if basis. The reporting change had no impact to previously reported segment net revenue, consolidated net revenue, earnings from operations, net earnings or net EPS. HP has reclassified certain prior-year amounts to conform to the current-year presentation as a result of the adoption of Accounting Standards Update (“ASU”) 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. This adoption had no impact on previously reported consolidated net revenue, net earnings or net EPS. For detailed discussion see Note 2, “Segment Information”. 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 HP’s Consolidated Financial Statements and accompanying notes. Actual results may differ materially from those estimates. Foreign Currency Translation HP predominantly uses the U.S. dollar as its functional currency. Assets and liabilities denominated in non-U.S. dollars are remeasured into U.S. dollars at current exchange rates for monetary assets and liabilities and at historical exchange rates for nonmonetary assets and liabilities. Net revenue, costs and expenses denominated in non-U.S. dollars are recorded in U.S. dollars at monthly average exchange rates prevailing during the period. HP includes gains or losses from foreign currency remeasurement in Interest and other, net in the Consolidated Statements of Earnings. Certain foreign subsidiaries designate the local currency as their functional currency, and HP records the translation of their assets and liabilities into U.S. dollars at the balance sheet dates as translation adjustments and includes them as a component of accumulated other comprehensive loss. Separation Transaction In connection with the Separation, HP and Hewlett Packard Enterprise entered into a separation and distribution agreement, an employee matters agreement and various other agreements which remain enforceable that provide a framework for the continuing relationships between the parties. For more information on the impacts of these agreements, see Note 7, “Supplementary Financial Information”, Note 14, “Litigation and Contingencies” and Note 15, “Guarantees, Indemnifications and Warranties”. Recently Adopted Accounting Pronouncements In February 2018, the FASB issued guidance, which eliminates the stranded tax effects in other comprehensive income resulting from the TCJA. Because the amendments only relate to the reclassification of the income tax effects of the TCJA, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from operations is not affected. HP early adopted this guidance in the third quarter of fiscal year 2019. The implementation of this guidance resulted in a $69 million reclassification from accumulated other comprehensive loss to accumulated deficit. In March 2017, the Financial Accounting Standards Board (“FASB”) issued guidance, which addresses the improvement of the presentation of net periodic pension and net periodic post-retirement benefit cost. The guidance requires entities to present the service cost component of net periodic benefit cost in the same income statement line item as other compensation costs arising from services rendered during the period. Additionally, the guidance requires that companies present the other components of the net periodic benefit cost separately from the line item that includes service cost and any other subtotal of income from operations. The amendments in this guidance are to be applied retrospectively for presentation in the Consolidated Statements of Earnings. A practical expedient allows companies to use the amount disclosed in its pension and other post-retirement plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. HP adopted this guidance in the first quarter of fiscal year 2019 and elected to use the practical expedient. The adoption of this guidance has no impact on net earnings. The reclassification resulted in an increase in total cost and expenses and a reduction in interest and other, net of $233 million for the twelve months ended October 31, 2018. In November 2016, the FASB issued guidance, which addresses the presentation of restricted cash in the statement of cash flows. The guidance requires entities to present the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. HP adopted this guidance in the first quarter of fiscal year 2019. The implementation of this guidance did not have any impact on its Consolidated Financial Statements. In October 2016, the FASB issued guidance, which amends the existing accounting for Intra-Entity Transfers of Assets Other Than Inventory. The guidance (Topic 740) requires an entity to recognize the income tax consequences of intra-entity transfers, other than inventory, when the transfer occurs. It also requires modified retrospective transition with a cumulative catch-up adjustment to opening retained earnings in the period of adoption. HP adopted this guidance in the first quarter of fiscal year 2019. The implementation of this guidance resulted in $353 million of net reduction to its prepaid tax asset adjusted through accumulated deficit. In the fourth quarter of fiscal year 2019, HP corrected this impact to $47 million by recording a deferred tax asset adjusted through accumulated deficit. In August 2016, the FASB issued guidance, which amends the existing accounting standards for the classification of certain cash receipts and cash payments on the statement of cash flows. HP adopted this guidance in the first quarter of fiscal year 2019. The implementation of this guidance did not have any impact on its Consolidated Financial Statements. In January 2016, the FASB issued guidance, which amends the existing accounting standards for the recognition and measurement of financial assets and financial liabilities. The guidance (Topic 825-10) primarily addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with other amendments related specifically to equity securities without readily determinable fair values applied prospectively. HP adopted this guidance in the first quarter of fiscal year 2019. The implementation of this guidance did not have a material impact on its Consolidated Financial Statements. In May 2014, the FASB issued guidance, which amends the existing accounting standards for revenue recognition. The amendments (Topic 606) are based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. HP adopted the new revenue standard in the first quarter of fiscal year 2019 using the modified retrospective method applied to contracts that were not completed as of November 1, 2018. HP recognized the net impact of adoption as an increase to accumulated deficit by $212 million , net of tax, on November 1, 2018. The primary changes that impact the Consolidated Financial Statements are as below: Variable consideration - HP estimates the transaction price for elements of consideration which are variable in nature. Certain distributor programs and incentive offerings which were recorded at the date the sales incentives were offered, are now recorded at the time of revenue recognition based on estimates. Costs to obtain a contract - The incremental costs to obtain a contract are primarily comprised of eligible sales commissions which were previously expensed as incurred. HP has capitalized such eligible sales commission costs for contracts with terms of more than one year and amortized those costs over the expected period of the benefit. The adoption has led to certain balance sheet reclassifications pertaining to return asset and liability and repurchase reserves which impacts accounts receivable, net, inventory, other current assets and other current liabilities balances. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2017, the FASB issued guidance, which amends the existing accounting standards for derivatives and hedging. The amendment improves the financial reporting of hedging relationships to better represent the economic results of an entity’s risk management activities in its financial statements and made certain targeted improvements to simplify the application of the hedge accounting guidance in current U.S. GAAP. HP is required to adopt the guidance in the first quarter of fiscal year 2020. Earlier adoption is permitted. Based on the current assessment, HP expects that the implementation of this guidance will not have a material impact on its Consolidated Financial Statements. In June 2016, the FASB issued guidance, which requires credit losses on financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, not based on incurred losses. Further, credit losses on available-for-sale debt securities should be recorded through an allowance for credit losses limited to the amount by which fair value is below amortized cost. HP is required to adopt the guidance in the first quarter of fiscal year 2021. Earlier adoption is permitted. HP is currently evaluating the timing and the impact of this guidance on the Consolidated Financial Statements. In February 2016, the FASB issued guidance (“Topic 842”), which amends the existing accounting standards for leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification. Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than twelve months. HP will adopt this guidance in the first quarter of fiscal year 2020 and will apply the modified retrospective transition option made available in July 2018 by the FASB, whereby comparative periods will not be retrospectively presented in the Consolidated Financial Statements. HP will also elect the package of practical expedients not to reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs and the lessee practical expedient to combine lease and non-lease components for certain asset classes. HP has established a cross-functional implementation team to assist in determining the scope of impact, identifying changes to its business processes, implementing a new system solution and evaluating changes to internal controls to support adoption of the new standard. HP currently expects the adoption of Topic 842 to result in an increase in right of use assets and a corresponding increase in lease liabilities on the Consolidated Balance Sheet of approximately $1.0 billion to $1.5 billion . Upon adoption, HP will also record revenue upfront on certain aspects of its MPS and DaaS offerings and will reflect the financing of these offerings as cash flows from financing activities on the Statement of Cash Flows. HP has substantially completed the process of quantifying the impacts that will result from applying the new guidance, and the assessment will be finalized during the first quarter of fiscal year 2020. Revenue Recognition General HP recognizes revenues at a point in time or over time depicting the transfer of promised goods or services to customers in an amount that reflects the consideration to which HP expects to be entitled in exchange for those goods or services. HP follows the five-step model for revenue recognition as summarized below: 1 . Identify the contract with a customer - A contract with customer exists when (i) it is approved and signed by all parties, (ii) each party’s rights and obligations can be identified, (iii) payment terms are defined, (iv) it has commercial substance and (v) the customer has the ability and intent to pay. HP evaluates customers’ ability to pay based on various factors like historical payment experience, financial metrics and customer credit scores. While the majority of our sales contracts contain standard terms and conditions, there are certain contracts with non-standard terms and conditions. 2. Identify the performance obligations in the contract - HP evaluates each performance obligation in an arrangement to determine whether it is distinct, such as hardware and/or service. A performance obligation constitutes distinct goods or services when the customer can benefit from such goods or services either on its own or together with other resources that are readily available to the customer and the performance obligation is distinct within the context of the contract. 3. Determine the transaction price - Transaction price is the amount of consideration to which HP expects to be entitled in exchange for transferring goods or services to the customer. If the transaction price includes a variable amount, HP estimates the amount it expects to be entitled to using either the expected value or most likely amount method. HP reduces the transaction price at the time of revenue recognition for customer and distributor programs and incentive offerings, rebates, promotions, other volume-based incentives and expected returns. HP uses estimates to determine the expected variable consideration for such programs based on factors like historical experience, expected consumer behavior and market conditions. HP has elected the practical expedient of not accounting for significant financing components if the period between revenue recognition and when the customer pays for the product or service is one year or less. 4. Allocate the transaction price to performance obligations in the contract - When a sales arrangement contains multiple performance obligations, such as hardware and/or services, HP allocates revenue to each performance obligation in proportion to their selling price. The selling price for each performance obligation is based on its SSP. HP establishes SSP using the price charged for a performance obligation when sold separately (“observable price”) and, in some instances, using the price established by management having the relevant authority. When observable price is not available, HP establishes SSP based on management judgment considering internal factors such as margin objectives, pricing practices and controls, customer segment pricing strategies and the product life-cycle. Consideration is also given to market conditions such as competitor pricing strategies and technology industry life cycles. 5. Recognize revenue when (or as) the performance obligation is satisfied - Revenue is recognized when, or as, a performance obligation is satisfied by transferring control of a promised good or service to a customer. HP generally invoices the customer upon delivery of the goods or services and the payments are due as per contract terms. For fixed price support or maintenance contracts that are in the nature of stand-ready obligations, payments are generally received in advance from customers and revenue is recognized on a straight-line basis over the duration of the contract. HP reports revenue net of any taxes collected from customers and remitted to government authorities, and the collected taxes are recorded as other current liabilities until remitted to the relevant government authority. HP includes costs related to shipping and handling in cost of revenue. HP records revenue on a gross basis when HP is a principal in the transaction and on a net basis when HP is acting as an agent between the customer and the vendor. HP considers several factors to determine whether it is acting as a principal or an agent, most notably whether HP is the primary obligor to the customer, has established its own pricing and has inventory and credit risks. Hardware HP transfers control of the products to the customer at the time the product is delivered to the customer and recognizes revenue accordingly, unless customer acceptance is uncertain or significant obligations to the customer remain unfulfilled. Services HP recognizes revenue from fixed-price support, maintenance and other service contracts over time depicting the pattern of service delivery and recognizes the costs associated with these contracts as incurred. Contract Assets and Liabilities Contract assets are rights to consideration in exchange for goods or services that HP has transferred to a customer when such right is conditional on something other than the passage of time. Such contract assets are not material to HP’s Consolidated Financial Statements. Contract liabilities are recorded as deferred revenues when amounts invoiced to customers are more than the revenues recognized or when payments are received in advance for fixed price support or maintenance contracts. The short-term and long-term deferred revenues are reported within the other current liabilities and other non-current liabilities respectively. Cost to obtain a contract and fulfillment cost Incremental direct costs of obtaining a contract primarily consist of sales commissions. HP has elected the practical expedient to expense as incurred the costs to obtain a contract with a benefit period equal to or less than one year. For contracts with a period of benefit greater than one year, HP capitalizes incremental costs of obtaining a contract with a customer and amortizes these costs over their expected period of benefit provided such costs are recoverable. Fulfillment costs consist of set-up and transition costs related to other service contracts. These costs generate or enhance resources of HP that will be used in satisfying the performance obligation in the future and are capitalized and amortized over the expected period of the benefit, provided such costs are recoverable. See Note 7, “Supplementary Financial Information” for details on net revenue by region, cost to obtain a contract and fulfillment cost, contract liabilities and value of remaining performance obligations. Transition disclosure In accordance with the modified retrospective method transition requirements, HP has presented the financial statement line items impacted and adjusted to compare to presentation under the prior GAAP for the Consolidated Balance Sheet as of October 31, 2019 and for Consolidated Statement of Earnings for fiscal year ended October 31, 2019. As of October 31, 2019 CONSOLIDATED BALANCE SHEET ITEMS As Reported Effect of Adoption Balances Without Adoption of Topic 606 In millions ASSETS Accounts receivable, net $ 6,031 $ (218 ) $ 5,813 Inventory 5,734 188 5,922 Other current assets 3,875 (188 ) 3,687 Other non-current assets $ 4,124 $ (31 ) $ 4,093 LIABILITIES AND STOCKHOLDERS' DEFICIT Other current liabilities $ 10,143 $ (435 ) $ 9,708 Accumulated deficit $ (818 ) $ 186 $ (632 ) For the fiscal year ended October 31, 2019 CONSOLIDATED STATEMENT OF EARNINGS ITEMS As Reported Effect of Adoption Balances Without Adoption of Topic 606 In millions Net revenue $ 58,756 $ (33 ) $ 58,723 Earnings from operations 3,877 (33 ) 3,844 Earnings before taxes 2,523 (33 ) 2,490 Benefit from taxes 629 7 636 Net earnings $ 3,152 $ (26 ) $ 3,126 Opening Balance Sheet Adjustments: The following table presents the adoption impact of the new accounting standards to HP’s previously reported financial statements: As Reported on October 31, 2018 Adjustments under Topic 606 Other (1) As Restated on November 1, 2018 In millions ASSETS Accounts receivable, net $ 5,113 $ 213 $ — $ 5,326 Inventory 6,062 (203 ) — 5,859 Other current assets 5,046 203 (90 ) 5,159 Other non-current assets $ 5,069 $ 33 $ 43 $ 5,145 LIABILITIES AND STOCKHOLDERS' DEFICIT Other current liabilities $ 8,852 $ 458 $ — $ 9,310 Accumulated other comprehensive loss (845 ) — (2 ) (847 ) Accumulated deficit $ (473 ) $ (212 ) $ (45 ) $ (730 ) (1) Other includes $47 million adjustment related to Topic 740. Stock-Based Compensation HP determines stock-based compensation expense based on the measurement date fair value of the award. HP recognizes compensation cost only for those awards expected to meet the service and performance vesting conditions on a straight-line basis over the requisite service period of the award. HP determines compensation costs at the aggregate grant level for service-based awards and at the individual vesting tranche level for awards with performance and/or market conditions. HP estimates the forfeiture rate based on its historical experience. Retirement and Post-Retirement Plans HP has various defined benefit, other contributory and non-contributory retirement and post-retirement plans. HP generally amortizes unrecognized actuarial gains and losses on a straight-line basis over the average remaining estimated service life of participants. In limited cases, HP amortizes actuarial gains and losses using the corridor approach. See Note 4, “Retirement and Post-Retirement Benefit Plans” for a full description of these plans and the accounting and funding policies. Advertising cost Costs to produce advertising are expensed as incurred during production. Costs to communicate advertising are expensed when the advertising is first run. Such costs totaled approximately $652 million , $568 million and $544 million in fiscal years 2019, 2018 and 2017, respectively. Restructuring and Other Charges HP records charges associated with management-approved restructuring plans to reorganize one or more of HP’s business segments, to remove duplicative headcount and infrastructure associated with business acquisitions or to simplify business processes and accelerate innovation. Restructuring charges can include severance costs to reduce a specified number of employees, enhanced early retirement incentives, infrastructure charges to vacate facilities and consolidate operations, and contract cancellation costs. HP records restructuring charges based on estimated employee terminations, committed early retirements and site closure and consolidation plans. HP accrues for severance and other employee separation costs under these actions when it is probable that benefits will be paid and the amount is reasonably estimable. The rates used in determining severance accruals are based on existing plans, historical experiences and negotiated settlements. Other charges include non-recurring costs, including those as a result of the Separation or information technology rationalization efforts, and are distinct from ongoing operational costs. Taxes on Earnings HP recognizes deferred tax assets and liabilities for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts using enacted tax rates in effect for the year the differences are expected to reverse. HP records a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized. HP records accruals for uncertain tax positions when HP believes that it is not more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. HP makes adjustments to these accruals when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. The provision for income taxes includes the effects of adjustments for uncertain tax positions, as well as any related interest and penalties. Accounts Receivable HP establishes an allowance for doubtful accounts for accounts receivable. HP records a specific reserve for individual accounts when HP becomes aware of specific customer circumstances, such as in the case of a bankruptcy filing or deterioration in the customer’s operating results or financial position. If there are additional changes in circumstances related to the specific customer, HP further adjusts estimates of the recoverability of receivables. HP maintains bad debt reserves for all other customers based on a variety of factors, including the use of third-party credit risk models that generate quantitative measures of default probabilities based on market factors, the financial condition of customers, the length of time receivables are past due, trends in the weighted-average risk rating for the portfolio, macroeconomic conditions, information derived from competitive benchmarking, significant one-time events and historical experience. The past due or delinquency status of a receivable is based on the contractual payment terms of the receivable. HP has third-party short-term financing arrangements intended to facilitate the working capital requirements of certain customers. These financing arrangements, which in certain cases provide for partial recourse, result in the transfer of HP’s trade receivables to a third party. HP reflects amounts transferred to, but not yet collected from the third party in accounts receivable in the Consolidated Balance Sheets. For arrangements involving an element of recourse, the fair value of the recourse obligation is measured using market data from similar transactions and reported as a current liability in the Consolidated Balance Sheets. Concentrations of Risk Financial instruments that potentially subject HP to significant concentrations of credit risk consist principally of cash and cash equivalents, investments, receivables from trade customers and contract manufacturers and derivatives. HP maintains cash and cash equivalents, investments, derivatives and certain other financial instruments with various financial institutions. These financial institutions are located in many different geographic regions, and HP’s policy is designed to limit exposure from any particular institution. As part of its risk management processes, HP performs periodic evaluations of the relative credit standing of these financial institutions. HP has not sustained material credit losses from instruments held at these financial institutions. HP utilizes derivative contracts to protect against the effects of foreign currency, interest rate and, on certain investment exposures. Such contracts involve the risk of non-performance by the counterparty, which could result in a material loss. The likelihood of which HP deems to be remote. HP sells a significant portion of its products through third-party distributors and resellers and, as a result, maintains individually significant receivable balances with these parties. If the financial condition or operations of these distributors’ and resellers’ aggregated business deteriorates substantially, HP’s operating results could be adversely affected. The ten largest distributor and reseller receivable balances, which were concentrated primarily in North America and Europe, collectively represented approximately 32% and 39% of gross accounts receivable as of October 31, 2019 and 2018, respectively. No single customer accounts for more than 10% of gross accounts receivable as of October 31, 2019 or 2018. Credit risk with respect to other accounts receivable is generally diversified due to HP’s large customer base and their dispersion across many different industries and geographic markets. HP performs ongoing credit evaluations of the financial condition of its third-party distributors, resellers and other customers and may require collateral, such as letters of credit and bank guarantees, in certain circumstances. HP utilizes outsourced manufacturers around the world to manufacture HP-designed products. HP may purchase product components from suppliers and sell those components to its outsourced manufacturers thereby creating receivable balances from the outsourced manufacturers. The three largest outsourced manufacturer receivable balances collectively represented 77% and 72% of HP’s supplier receivables of $1,165 million and $1,074 million as of October 31, 2019 and 2018, respectively. HP includes the supplier receivables in Other current assets in the Consolidated Balance Sheets on a gross basis. HP’s credit risk associated with these receivables is mitigated wholly or in part, by the amount HP owes to these outsourced manufacturers, as HP generally has the legal right to offset its payables to the outsourced manufacturers against these receivables. HP does not reflect the sale of these components in net revenue and does not recognize any profit on these component sales until the related products are sold by HP, at which time any profit is recognized as a reduction to cost of revenue. HP obtains a significant number of components from single source suppliers due to technology, availability, price, quality or other considerations. The loss of a single source supplier, the deterioration of HP’s relationship with a single source supplier, or any unilateral modification to the contractual terms under which HP is supplied components by a single source supplier could adversely affect HP’s net revenue and gross margins. Upon completion of the Separation on November 1, 2015, HP recorded net income tax indemnification receivables from Hewlett Packard Enterprise for certain income tax liabilities that HP is jointly and severally liable for, but for which it is indemnified by Hewlett Packard Enterprise under the tax matters agreement (“TMA”). The TMA was terminated during the fourth quarter of fiscal year 2019. The net payable as of October 31, 2019 was $98 million and net receivable as of October 31, 2018 was $1.0 billion . Inventory HP values inventory at the lower of cost or market. Cost is computed using standard cost which approximates actual cost on a first-in, first-out basis. Adjustments, if required, to reduce the cost of inventory to market (net realizable value) are made, for estimated excess, obsolete or impaired balances. Property, Plant and Equipment, Net HP reflects property, plant and equipment at cost less accumulated depreciation. HP capitalizes additions and improvements and expenses maintenance and repairs as incurred. Depreciation expense is recognized on a straight-line basis over the estimated useful lives of the assets. Estimated useful lives are five to 40 years for buildings and improvements and three to 15 years for machinery and equipment. HP depreciates leasehold improvements over the life of the lease or the asset, whichever is shorter. HP depreciates equipment held for lease over the initial term of the lease to the equipment’s estimated residual value. On retirement or disposition, the asset cost and related accumulated depreciation are removed from the Consolidated Balance Sheets with any gain or loss recognized in the Consolidated Statements of Earnings. Internal Use Software and Cloud Computing Arrangements HP capitalizes external costs and directly attributable internal costs to acquire or create internal use software which are incurred subsequent to the completion of the preliminary project stage. These costs relate to activities such as software design, configuration, coding, testing, and installation. Costs related to post-implementation activities such as training and maintenance are expensed as incurred. Once the software is substantially complete and ready for its intended use, capitalized development costs are amortized straight-line over the estimated useful life of the software, not to exceed five years . HP also enters into certain clo

Segment Reporting [Abstract]
Segment Information	Segment Information HP is a leading global provider of personal computing and other access devices, imaging and printing products, and related technologies, solutions and services. HP sells to individual consumers, SMBs and large enterprises, including customers in the government, health and education sectors. HP’s operations are organized into three reportable segments: Personal Systems, Printing and Corporate Investments. HP’s organizational structure is based on many factors that the chief operating decision maker (“CODM”) uses to evaluate, view and run its business operations, which include, but are not limited to, customer base and homogeneity of products and technology. The segments are based on this organizational structure and information reviewed by HP’s CODM to evaluate segment results. The CODM uses several metrics to evaluate the performance of the overall business, including earnings from operations, and uses these results to allocate resources to each of the segments. A summary description of each segment is as follows: Personal Systems offers commercial and consumer desktop and notebook PCs, workstations, thin clients, commercial mobility devices, retail POS systems, displays and other related accessories, software, support and services. HP groups commercial notebooks, commercial desktops, commercial services, commercial mobility devices, commercial detachables and convertibles, workstations, retail POS systems and thin clients into commercial PCs and consumer notebooks, consumer desktops, consumer services and consumer detachables into consumer PCs when describing performance in these markets. Described below are HP’s global business capabilities within Personal Systems: • Commercial PCs are optimized for use by enterprise, public sector and SMB customers, with a focus on robust designs, security, serviceability, connectivity, reliability and manageability in networked and cloud- based environments. Additionally, HP offers a range of services and solutions to enterprise, public sector and SMB customers to help them manage the lifecycle of their PC and mobility installed base. • Consumer PCs are optimized for consumer usage, focusing on gaming, consuming multi-media for entertainment, managing personal life activities, staying connected, sharing information, getting things done for work including creating content, staying informed and security. Personal Systems groups its global business capabilities into the following business units when reporting business performance: • Notebooks consists of consumer notebooks, commercial notebooks, mobile workstations and commercial mobility devices; • Desktops includes consumer desktops, commercial desktops, thin clients, and retail POS systems; • Workstations consists of desktop workstations and accessories; and • Other consists of consumer and commercial services as well as other Personal Systems capabilities. Printing provides consumer and commercial printer hardware, supplies, solutions and services, as well as scanning devices. Printing is also focused on imaging solutions in the commercial and industrial markets. Described below are HP’s global business capabilities within Printing. • Office Printing Solutions delivers HP’s office printers, supplies, services and solutions to SMBs and large enterprises. It also includes some Samsung-branded and OEM hardware and solutions. HP goes to market through its extensive channel network and directly with HP sales. • Home Printing Solutions delivers innovative printing products, supplies, services and solutions for the home, home business and micro business customers utilizing both HP’s Ink and Laser technologies (including laser technology from some Samsung-branded products). • Graphics Solutions delivers large-format, commercial and industrial solutions and supplies to print service providers and packaging converters through a wide portfolio of printers and presses (HP DesignJet, HP Latex, HP Stitch, HP Indigo and HP PageWide Web Presses) and related components. • 3D Printing & Digital Manufacturing offers a portfolio of additive manufacturing solutions and supplies to help customers succeed in their additive and digital manufacturing journey. HP offers complete solutions in collaboration with an ecosystem of partners. Printing groups its global business capabilities into the following business units when reporting business performance: • Commercial Hardware consists of office printing solutions, graphics solutions and 3D Printing & Digital Manufacturing, excluding supplies; • Consumer Hardware consists of home printing solutions, excluding supplies; and • Supplies comprises a set of highly innovative consumable products, ranging from ink and laser cartridges to media, graphics supplies and 3D Printing & Digital Manufacturing supplies, for recurring use in consumer and commercial hardware. Corporate Investments includes HP Labs and certain business incubation and investment projects. The accounting policies HP uses to derive segment results are substantially the same as those used by HP in preparing these financial statements. HP derives the results of the business segments directly from its internal management reporting system. HP does not allocate certain operating expenses, which it manages at the corporate level, to its segments. These unallocated amounts include certain corporate governance costs and infrastructure investments, stock-based compensation expense, restructuring and other charges, acquisition-related charges and amortization of intangible assets. Pursuant to the adoption of ASU 2017-07 in the first quarter of fiscal year of 2019, HP now reclassifies market-related retirement credits and all other components (excluding the service cost component) of net periodic benefit cost to Interest and other, net in Consolidated Statement of Earnings. HP reflected this change in prior reporting periods on an as-if basis. This adoption did not have a material impact to previously reported segment earnings from operations. Realignment Effective at the beginning of its first quarter of fiscal year 2019, HP implemented an organizational change to align its business unit financial reporting more closely with its current business structure. The organizational change resulted in the transfer of certain Samsung-branded product categories from Commercial to Consumer within the Printing segment. HP reflected this change to its business unit information in prior reporting periods on an as-if basis. The reporting change had no impact to previously reported segment net revenue, consolidated net revenue, earnings from operations, net earnings or net EPS. Segment Operating Results from Operations and the reconciliation to HP consolidated results were as follows: For the fiscal years ended October 31, 2019 2018 2017 In millions Net revenue: Notebooks $ 22,928 $ 22,547 $ 19,782 Desktops 12,046 11,567 10,298 Workstations 2,389 2,246 2,042 Other 1,331 1,301 1,199 Personal Systems 38,694 37,661 33,321 Supplies 12,921 13,575 12,524 Commercial Hardware 4,612 4,514 3,792 Consumer Hardware 2,533 2,716 2,412 Printing 20,066 20,805 18,728 Corporate Investments 2 5 8 Total segment net revenue 58,762 58,471 52,057 Other (6 ) 1 (1 ) Total net revenue $ 58,756 $ 58,472 $ 52,056 Earnings before taxes: Personal Systems $ 1,898 $ 1,402 $ 1,206 Printing 3,202 3,314 3,142 Corporate Investments (96 ) (82 ) (87 ) Total segment earnings from operations $ 5,004 $ 4,634 $ 4,261 Corporate and unallocated costs and other (404 ) (200 ) (181 ) Stock-based compensation expense (297 ) (268 ) (224 ) Restructuring and other charges (275 ) (132 ) (362 ) Acquisition-related charges (35 ) (123 ) (125 ) Amortization of intangible assets (116 ) (80 ) (1 ) Interest and other, net (1,354 ) (818 ) (92 ) Total earnings before taxes $ 2,523 $ 3,013 $ 3,276 Segment Assets HP allocates assets to its business segments based on the segments primarily benefiting from the assets.

(3) Includes reclassification of liability related to the Enhanced Early Retirement (“EER”) plan of $6M for certain healthcare and medical savings account benefits to pension and other post retirement plans. See Note 4 “Retirement and Post-Retirement Benefit Plans” for further information. Fiscal 2020 Plan On September 30, 2019, HP’s Board of Directors approved the Fiscal 2020 Plan intended to optimize and simplify its operating model and cost structure that HP expects will be implemented through fiscal 2022. HP expects to reduce global headcount by approximately 7,000 to 9,000 employees through a combination of employee exits and voluntary EER. HP estimates that it will incur pre-tax charges of approximately $1.0 billion relating to labor and non-labor actions. HP expects to incur approximately $0.9 billion primarily in labor costs related to workforce reductions and the remaining costs will relate to infrastructure, non-labor actions and other charges. Fiscal 2017 Plan On October 10, 2016, HP’s Board of Directors approved the Fiscal 2017 Plan, which included severance costs related to labor actions and infrastructure costs related to non-labor actions and other charges. Approximately 5,300 employees exited as part of the Fiscal 2017 Plan. HP incurred $390 million in severance costs and $305 million in infrastructure costs related to non-labor and other charges. The Fiscal 2017 Plan is substantially complete. HP does not expect any further costs associated with the plan. Other charges Other charges include non-recurring costs, including those as a result of the Separation or information technology rationalization efforts, and are distinct from ongoing operational costs. These costs primarily relate to information technology costs such as advisory, consulting and non-recurring labor costs. HP incurred $28 million , $33 million and $135 million of other charges in fiscal year 2019, 2018 and 2017, respectively.

Retirement Benefits [Abstract]
Retirement and Post-Retirement Benefit Plans	Retirement and Post-Retirement Benefit Plans Defined Benefit Plans HP sponsors a number of defined benefit pension plans worldwide. The most significant defined benefit plan, the HP Inc. Pension Plan (“Pension Plan”) is a frozen plan in the United States. HP reduces the benefit payable to certain U.S. employees under the Pension Plan for service before 1993, if any, by any amounts due to the employee under HP’s frozen defined contribution Deferred Profit-Sharing Plan (“DPSP”). At October 31, 2019 and 2018, the fair value of plan assets of the DPSP was $543 million and $536 million , respectively. The DPSP obligations are equal to the plan assets and are recognized as an offset to the Pension Plan when HP calculates its defined benefit pension cost and obligations. The Pension Plan and the DPSP both remain entirely with HP post-Separation. Post-Retirement Benefit Plans HP sponsors retiree health and welfare benefit plans, of which the most significant are in the United States. Under the HP Inc. Retiree Welfare Benefits Plan, certain pre-2003 retirees and grandfathered participants with continuous service to HP since 2002 are eligible to receive partially-subsidized medical coverage based on years of service at retirement. HP’s share of the premium cost is capped for all subsidized medical coverage provided under the HP Inc. Retiree Welfare Benefits Plan. HP currently leverages the employer group waiver plan process to provide HP Inc. Retiree Welfare Benefits Plan post-65 prescription drug coverage under Medicare Part D, thereby giving HP access to federal subsidies to help pay for retiree benefits. Certain employees not grandfathered for partially subsidized medical coverage under the above programs, and employees hired after 2002 but before August 2008, are eligible for credits under the HP Inc. Retiree Welfare Benefits Plan. Credits offered after September 2008 are provided in the form of matching credits on employee contributions made to a voluntary employee beneficiary association upon attaining age 45 or as part of early retirement programs. On retirement, former employees may use these credits for the reimbursement of certain eligible medical expenses, including premiums required for coverage. Defined Contribution Plans HP offers various defined contribution plans for U.S. and non-U.S. employees. Total defined contribution expense was $107 million in fiscal year 2019, $110 million in fiscal year 2018 and $103 million in fiscal year 2017. U.S. employees are automatically enrolled in the HP Inc. 401(k) Plan when they meet eligibility requirements, unless they decline participation. The employer matching contributions in the HP Inc. 401(k) Plan is 100% of an employee’s contributions, up to a maximum of 4% of eligible compensation.

(2) The fair value of corporate, government and asset-backed debt securities is based on observable inputs of comparable market transactions. Also included in this category is debt issued by national, state and local governments and agencies. (3) Department of Labor 103-12 IE (Investment Entity) designation is for plan assets held by two or more unrelated employee benefit plans which includes limited partnerships and venture capital partnerships. Certain common collective trusts and interests in 103-12 entities are valued using NAV as a practical expedient. (4) Includes publicly traded funds of investment companies that are registered with the SEC, funds that are not publicly traded and a non-U.S. fund-of-fund arrangement. The non-U.S. fund-of-fund arrangement is a custom portfolio valued at NAV consisting primarily of fixed income and common contractual funds. (5) Includes cash and cash equivalents such as short-term marketable securities. Cash and cash equivalents include money market funds, which are valued based on NAV. Other assets were classified in the fair value hierarchy based on the lowest level input (e.g., quoted prices and observable inputs) that is significant to the fair value measure in its entirety. (6) Includes primarily reverse repurchase agreements, unsettled transactions, and derivative instruments. (7) Alternative Investments primarily include private equities and hedge funds. The valuation of alternative investments, such as limited partnerships and joint ventures, may require significant management judgment. For alternative investments, valuation is based on NAV as reported by the asset manager or investment company and adjusted for cash flows, if necessary. In making such an assessment, a variety of factors are reviewed by management, including but not limited to the timeliness of NAV as reported by the asset manager and changes in general economic and market conditions subsequent to the last NAV reported by the asset manager. • Private equities include limited partnerships such as equity, buyout, venture capital, real estate and other similar funds that invest in the United States and internationally where foreign currencies are hedged. • Hedge funds include limited partnerships that invest both long and short primarily in common stocks and credit, relative value, event-driven equity, distressed debt and macro strategies. Management of the hedge funds has the ability to shift investments from value to growth strategies, from small to large capitalization stocks and bonds, and from a net long position to a net short position. (8) The Common Contractual Fund is an investment arrangement in which institutional investors pool their assets. Units may be acquired in different sub-funds focused on equities, fixed income, alternative investments and emerging markets. Each sub-fund is invested in accordance with the fund’s investment objective and units are issued in relation to each sub-fund. While the sub-funds are not publicly traded, the custodian strikes a NAV either once or twice a month, depending on the sub-fund. These assets are valued using NAV as a practical expedient. Plan Asset Allocations Refer to the fair value hierarchy table above for actual assets allocations across the benefit plans. The weighted-average target asset allocations across the benefit plans represented in the fair value tables above were as follows: 2019 Target Allocation Asset Category U.S. Defined Benefit Plans Non-U.S. Defined Post-Retirement Equity-related investments 29.4 % 40.6 % 48.2 % Debt securities 70.6 % 36.0 % 36.1 % Real estate — 6.2 % — Cash and cash equivalents — 2.4 % 15.7 % Other — 14.8 % — Total 100.0 % 100.0 % 100.0 % Investment Policy HP’s investment strategy is to seek a competitive rate of return relative to an appropriate level of risk depending on the funded status of each plan and the timing of expected benefit payments. The majority of the plans’ investment managers employ active investment management strategies with the goal of outperforming the broad markets in which they invest. Risk management practices include diversification across asset classes and investment styles and periodic rebalancing toward asset allocation targets. A number of the plans’ investment managers are authorized to utilize derivatives for investment or liability exposures, and HP may utilize derivatives to affect asset allocation changes or to hedge certain investment or liability exposures. The target asset allocation selected for each U.S. plan reflects a risk/return profile HP believes is appropriate relative to each plan’s liability structure and return goals. HP conducts periodic asset-liability studies for U.S. plans to model various potential asset allocations in comparison to each plan’s forecasted liabilities and liquidity needs and to develop a policy glide path which adjusts the asset allocation with funded status. A 2018 asset-liability study reconfirmed the current policy glide path for the U.S. pension plan. Due to higher interest rates at the beginning of fiscal year 2019, the investment portfolio interest rate exposure was increased in accordance with the policy hedge path. HP invests a portion of the U.S. defined benefit plan assets and post-retirement benefit plan assets in private market securities such as private equity funds to provide diversification and a higher expected return on assets. Outside the United States, asset allocation decisions are typically made by an independent board of trustees for the specific plan. As in the United States, investment objectives are designed to generate returns that will enable the plan to meet its future obligations. In some countries, local regulations may restrict asset allocations, typically leading to a higher percentage of investment in fixed income securities than would otherwise be deployed. HP reviews the investment strategy and provides a recommended list of investment managers for each country plan, with final decisions on asset allocation and investment managers made by the board of trustees for the specific plan. Basis for Expected Long-Term Rate of Return on Plan Assets The expected long-term rate of return on plan assets reflects the expected returns for each major asset class in which the plan invests and the weight of each asset class in the target mix. Expected asset returns reflect the current yield on government bonds, risk premiums for each asset class and expected real returns which considers each country’s specific inflation outlook. Because HP’s investment policy is to employ primarily active investment managers who seek to outperform the broader market, the expected returns are adjusted to reflect the expected additional returns net of fees. Retirement Incentive Program As part of the Fiscal 2020 Plan, HP announced the voluntary EER program for its U.S. employees in October 2019. Voluntary participation in the EER program was limited to those employees who are at least 50 years old with 20 or more years of service at HP. Employees accepted into the EER program will leave HP on dates ranging from December 31, 2019 to September 30, 2020. The EER benefit will be a cash lump sum payment which is calculated based on years of service at HP at the time of the retirement and ranging from 13 to 52 weeks of pay. All employees participating in the EER program are offered the opportunity to continue health care coverage at the active employee contribution rates for up to 36 months following retirement. In addition, HP is providing up to $12,000 in employer credits under the Retirement Medical Savings Account program. HP will recognize a special termination benefits expense as restructuring and other charges. Future Contributions and Funding Policy In fiscal year 2020 , HP expects to contribute approximately $76 million to its non-U.S. pension plans, $36 million to cover benefit payments to U.S. non-qualified plan participants and $6 million to cover benefit claims for HP’s post-retirement benefit plans. HP’s policy is to fund its pension plans so that it makes at least the minimum contribution required by local government, funding and taxing authorities. Estimated Future Benefits Payments As of October 31, 2019 , HP estimates that the future benefits payments for the retirement and post-retirement plans are as follows: Fiscal year U.S. Defined Benefit Plans Non-U.S. Defined Benefit Plans Post-Retirement Benefit Plans In millions 2020 $ 730 $ 40 $ 40 2021 752 34 36 2022 769 39 32 2023 788 40 29 2024 809 45 28 Next five fiscal years to October 31, 2029 4,020 276 135

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation HP’s stock-based compensation plans include incentive compensation plans and an employee stock purchase plan. Stock-Based Compensation Expense and Related Income Tax Benefits for Operations Stock-based compensation expense and the resulting tax benefits for operations were as follows: For the fiscal years ended October 31 2019 2018 2017 In millions Stock-based compensation expense $ 297 $ 268 $ 224 Income tax benefit (47 ) (59 ) (71 ) Stock-based compensation expense, net of tax $ 250 $ 209 $ 153 Cash received from option exercises and purchases under the HP Inc. 2011 Employee Stock Purchase Plan (the “2011 ESPP”) was $59 million in fiscal year 2019, $158 million in fiscal year 2018 and $118 million in fiscal year 2017. The benefit realized for the tax deduction from option exercises in fiscal years 2019, 2018 and 2017 was $3 million , $23 million and $15 million , respectively. Stock-Based Incentive Compensation Plans HP’s stock-based incentive compensation plans include equity plans adopted in 2004 and 2000, as amended and restated (“principal equity plans”), as well as various equity plans assumed through acquisitions under which stock-based awards are outstanding. Stock-based awards granted under the principal equity plans include restricted stock awards, stock options and performance-based awards. Employees meeting certain employment qualifications are eligible to receive stock-based awards. The aggregate number of shares of HP’s stock authorized for issuance under the 2004 principal equity plan is 593.1 million . No further grants may be made under the 2000 principal equity plan and all outstanding awards under this plan will remain outstanding according to the terms of the plan. Restricted stock awards are non-vested stock awards that may include grants of restricted stock or restricted stock units. Restricted stock awards and cash-settled awards are generally subject to forfeiture if employment terminates prior to the lapse of the restrictions. Such awards generally vest one to three years from the date of grant. During the vesting period, ownership of the restricted stock cannot be transferred. Restricted stock has the same dividend and voting rights as common stock and is considered to be issued and outstanding upon grant. The dividends paid on restricted stock are non-forfeitable. Restricted stock units do not have the voting rights of common stock, and the shares underlying restricted stock units are not considered issued and outstanding upon grant. However, shares underlying restricted stock units are included in the calculation of diluted net EPS. Restricted stock units have forfeitable dividend equivalent rights equal to the dividend paid on common stock. HP expenses the fair value of restricted stock awards ratably over the period during which the restrictions lapse. The majority of restricted stock units issued by HP contain only service vesting conditions. However, starting in fiscal year 2014, HP began granting performance-adjusted restricted stock units that vest only on the satisfaction of both service and the achievement of certain performance goals including market conditions prior to the expiration of the awards. Stock options granted under the principal equity plans are generally non-qualified stock options, but the principal equity plans permit some options granted to qualify as incentive stock options under the U.S. Internal Revenue Code. Stock options generally vest over three to four years from the date of grant. The exercise price of a stock option is equal to the closing price of HP’s stock on the option grant date. The majority of stock options issued by HP contain only service vesting conditions. However, starting in fiscal year 2011 through fiscal year 2016, HP granted performance-contingent stock options that vest only on the satisfaction of both service and market conditions prior to the expiration of the awards. Restricted Stock Units HP uses the closing stock price on the grant date to estimate the fair value of service-based restricted stock units. HP estimates the fair value of restricted stock units subject to performance-adjusted vesting conditions using a combination of the closing stock price on the grant date and the Monte Carlo simulation model. The weighted-average fair value and the assumptions used to measure the fair value of restricted stock units subject to performance-adjusted vesting conditions in the Monte Carlo simulation model were as follows: For the fiscal years ended October 31 2019 2018 2017 Weighted-average fair value (1) $ 27 $ 24 $ 20 Expected volatility (2) 26.5 % 29.5 % 30.5 % Risk-free interest rate (3) 2.7 % 1.9 % 1.4 % Expected performance period in years (4) 2.9 2.9 2.9 (1) The weighted-average fair value was based on performance-adjusted restricted stock units granted during the period. (2) The expected volatility was estimated using the historical volatility derived from HP’s common stock. (3) The risk-free interest rate was estimated based on the yield on U.S. Treasury zero-coupon issues. (4) The expected performance period was estimated based on the length of the remaining performance period from the grant date. A summary of restricted stock units activity is as follows: As of October 31 2019 2018 2017 Shares Weighted- Shares Weighted- Shares Weighted- In thousands In thousands In thousands Outstanding at beginning of year 30,784 $ 18 31,822 $ 14 28,710 $ 13 Granted 17,216 $ 22 16,364 $ 21 15,858 $ 16 Vested (16,934 ) $ 16 (15,339 ) $ 15 (11,915 ) $ 14 Forfeited (1,106 ) $ 20 (2,063 ) $ 17 (831 ) $ 14 Outstanding at end of year 29,960 $ 21 30,784 $ 18 31,822 $ 14 The total grant date fair value of restricted stock units vested in fiscal years 2019, 2018 and 2017 was $273 million , $224 million and $162 million , respectively. As of October 31, 2019 , total unrecognized pre-tax stock-based compensation expense related to non-vested restricted stock units for operations was $267 million , which is expected to be recognized over the remaining weighted-average vesting period of 1.4 years. Stock Options HP utilizes the Black-Scholes-Merton option pricing formula to estimate the fair value of stock options subject to service-based vesting conditions. HP estimates the fair value of stock options subject to performance-contingent vesting conditions using a combination of a Monte Carlo simulation model and a lattice model as these awards contain market conditions. The weighted-average fair value and the assumptions used to measure fair value were as follows: For the fiscal years ended October 31 2019 2018 2017 Weighted-average fair value (1) $ 3 $ 5 $ 4 Expected volatility (2) 29.8 % 29.4 % 28.0 % Risk-free interest rate (3) 1.7 % 2.5 % 1.9 % Expected dividend yield (4) 3.7 % 2.6 % 2.8 % Expected term in years (5) 6.0 5.0 5.5 (1) The weighted-average fair value was based on stock options granted during the period. (2) For all awards granted in fiscal year 2019 and 2018, expected volatility was estimated based on a blended volatility ( 50% historical volatility and 50% implied volatility from traded options on HP's common stock). For the awards granted in fiscal year 2017, expected volatility was estimated using the leverage-adjusted average of the term-matching volatilities of peer companies due to the lack of volume of forward traded options, which precluded the use of implied volatility. (3) The risk-free interest rate was estimated based on the yield on U.S. Treasury zero-coupon issues. (4) The expected dividend yield represents a constant dividend yield applied for the duration of the expected term of the award. (5) For awards subject to service-based vesting, the expected term was estimated using a simplified method; and for performance-contingent awards, the expected term represents an output from the lattice model. A summary of stock options activity is as follows: As of October 31 2019 2018 2017 Shares Weighted- Weighted- Aggregate Shares Weighted- Weighted- Aggregate Shares Weighted- Weighted- Aggregate In In years In In In years In In In years In Outstanding at beginning of year 7,086 $ 14 18,067 $ 13 28,218 $ 12 Granted 2,451 $ 17 54 $ 21 104 $ 19 Exercised (2,429 ) $ 13 (10,644 ) $ 13 (9,407 ) $ 11 Forfeited/cancelled/expired (15 ) $ 10 (391 ) $ 16 (848 ) $ 17 Outstanding at end of year 7,093 $ 16 5.7 $ 15 7,086 $ 14 4.2 $ 73 18,067 $ 13 4.2 $ 152 Vested and expected to vest 7,093 $ 16 5.7 $ 15 7,084 $ 14 4.2 $ 73 17,692 $ 13 4.1 $ 149 Exercisable 4,707 $ 14 3.6 $ 15 4,707 $ 14 3.7 $ 49 10,898 $ 12 3.1 $ 102 The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value that option holders would have realized had all option holders exercised their options on the last trading day of fiscal years 2019, 2018 and 2017. The aggregate intrinsic value is the difference between HP’s closing stock price on the last trading day of the fiscal year and the exercise price, multiplied by the number of in-the-money options. The total intrinsic value of options exercised in fiscal years 2019, 2018 and 2017 was $20 million , $109 million and $77 million , respectively. The total grant date fair value of options vested in fiscal years 2019, 2018 and 2017 was $9 million , $12 million and $19 million , respectively. As of October 31, 2019 , total unrecognized pre-tax stock-based compensation expense related to stock options was $8 million , which is expected to be recognized over a weighted-average vesting period of 2 years. Employee Stock Purchase Plan HP sponsors the 2011 ESPP, pursuant to which eligible employees may contribute up to 10% of base compensation, subject to certain income limits, to purchase shares of HP’s common stock. Pursuant to the terms of the 2011 ESPP, employees purchase stock under the 2011 ESPP at a price equal to 95% of HP’s closing stock price on the purchase date.

Taxes on Earnings

Taxes on Earnings	12 Months Ended

Income Tax Disclosure [Abstract]
Taxes on Earnings	Taxes on Earnings Provision for Taxes On December 22, 2017, the TCJA was enacted into law. Given the significance of the legislation, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which allows registrants to record provisional amounts during a one year “measurement period”. As of January 31, 2019, HP completed its accounting for the tax effects of the TCJA with no material changes to the provisional amounts recorded during the measurement period. In January 2018, the FASB released guidance on the accounting for tax on the Global Minimum Tax provisions of TCJA. The Global Minimum Tax provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. HP has elected to treat Global Minimum Tax inclusions as period costs. The domestic and foreign components of earnings before taxes were as follows: For the fiscal years ended October 31 2019 2018 2017 In millions U.S. $ (1,021 ) $ 242 $ (14 ) Non-U.S. 3,544 2,771 3,290 $ 2,523 $ 3,013 $ 3,276 The (benefit from) provision for taxes on earnings was as follows: For the fiscal years ended October 31 2019 2018 2017 In millions U.S. federal taxes: Current $ (987 ) $ 751 $ 189 Deferred 149 (3,132 ) 197 Non-U.S. taxes: Current 386 528 302 Deferred (3 ) (563 ) 4 State taxes: Current (160 ) 61 20 Deferred (14 ) 41 38 $ (629 ) $ (2,314 ) $ 750 As a result of U.S. tax reform, HP revised its estimated annual effective tax rate to reflect the change in the U.S. federal statutory tax rate from 35% to 23.3% in fiscal year 2018, under transitional tax rate rules, and 21% in fiscal year 2019. The differences between the U.S. federal statutory income tax rate and HP’s effective tax rate were as follows: For the fiscal years ended October 31 2019 2018 2017 U.S. federal statutory income tax rate from operations 21.0 % 23.3 % 35.0 % State income taxes from operations, net of federal tax benefit 1.5 % 0.5 % 1.4 % Impact of foreign earnings, net (6.4 )% (10.9 )% (13.2 )% Foreign-derived intangible income deduction (2.3 )% — % — % Global Minimum Tax 4.3 % — % — % U.S. Tax Reform impacts (2.6 )% (35.8 )% — % Research and development (“R&D”) credit (1.1 )% (0.7 )% (0.5 )% Valuation allowances (3.7 )% (9.3 )% (1.9 )% Uncertain tax positions and audit settlements (41.1 )% (50.3 )% 0.4 % Indemnification related items 6.8 % 5.2 % (0.3 )% Other, net (1.3 )% 1.2 % 2.0 % (24.9 )% (76.8 )% 22.9 % The jurisdictions with favorable tax rates that have the most significant effective tax rate impact in the periods presented include Puerto Rico, Singapore, China, Malaysia and Ireland. In fiscal year 2019, HP recorded $1.3 billion of net income tax benefits related to discrete items in the provision for taxes. This amount includes tax benefits related to audit settlements of $1.0 billion , $75 million due to ability to utilize tax attributes, $57 million of restructuring benefits and net valuation allowance releases of $94 million . HP also recorded benefits of $78 million related to U.S. tax reform as a result of new guidance issued by the U.S. Internal Revenue Service (“IRS”). These benefits were partially offset by uncertain tax position charges of $51 million . In fiscal year 2019, in addition to the discrete items mentioned above, HP recorded excess tax benefits of $20 million associated with stock options, restricted stock units and performance-adjusted restricted stock units. In fiscal year 2018, HP recorded $2.8 billion of net income tax benefits related to discrete items in the provision for taxes which include impacts of the TCJA. HP had not yet completed its analysis of the full impact of the TCJA. However, as of October 31, 2018, HP recorded a provisional tax benefit of $760 million related to $5.6 billion net benefit for the decrease in its deferred tax liability on unremitted foreign earnings, partially offset by $3.3 billion net expense for the deemed repatriation tax payable in installments over eight years, a $1.2 billion net expense for the remeasurement of its deferred assets and liabilities to the new U.S. statutory tax rate and a $317 million valuation allowance on net expense related to deferred tax assets that are expected to be realized at a lower rate. HP also recorded tax benefits related to audit settlements of $1.5 billion and valuation allowance releases of $601 million pertaining to a change in our ability to utilize certain foreign and U.S. deferred tax assets due to a change in our geographic earnings mix. These benefits were partially offset by other net tax charges of $34 million . In fiscal year 2018, in addition to the discrete items mentioned above, HP recorded excess tax benefits of $42 million associated with stock options, restricted stock units and performance-adjusted restricted stock units. In fiscal year 2017, HP recorded $72 million of net income tax benefits related to discrete items in the provision for taxes. These amounts primarily include tax benefits of $84 million related to restructuring and other charges, $12 million related to U.S. federal provision to return adjustments, $45 million related to Samsung acquisition-related charges, and $13 million of other net tax benefits. In addition, HP recorded tax charges of $11 million related to changes in state valuation allowances, $22 million of state provision to return adjustments, and $49 million related to uncertain tax positions. In fiscal year 2017, in addition to the discrete items mentioned above, HP recorded excess tax benefits of $19 million associated with stock options, restricted stock units and performance-adjusted restricted stock units, which are reflected in the Consolidated Statements of Earnings as a component of the provision for income taxes. As a result of certain employment actions and capital investments HP has undertaken, income from manufacturing and services in certain countries is subject to reduced tax rates, and in some cases is wholly exempt from taxes, through 2027 . The gross income tax benefits attributable to these actions and investments were estimated to be $386 million ( $0.25 diluted EPS) in fiscal year 2019, $578 million ( $0.35 diluted net EPS) in fiscal year 2018 and $471 million ( $0.28 diluted net EPS) in fiscal year 2017. Uncertain Tax Positions A reconciliation of unrecognized tax benefits is as follows: For the fiscal years ended October 31 2019 2018 2017 In millions Balance at beginning of year $ 7,771 $ 10,808 $ 10,858 Increases: For current year’s tax positions 79 66 52 For prior years’ tax positions 172 101 85 Decreases: For prior years’ tax positions (37 ) (248 ) (181 ) Statute of limitations expirations (15 ) (3 ) (1 ) Settlements with taxing authorities (7,041 ) (2,953 ) (5 ) Balance at end of year $ 929 $ 7,771 $ 10,808 As of October 31, 2019, the amount of unrecognized tax benefits was $929 million , of which up to $803 million would affect HP’s effective tax rate if realized. As of October 31, 2018, the amount of unrecognized tax benefits was $7.8 billion of which up to $1.5 billion would affect HP’s effective tax rate if realized. The amount of unrecognized tax benefits decreased by $6.8 billion primarily related to the resolution of various audits. HP recognizes interest income from favorable settlements and interest expense and penalties accrued on unrecognized tax benefits in the provision for taxes in the Consolidated Statements of Earnings. As of October 31, 2019, 2018 and 2017, HP had accrued $56 million , $160 million and $257 million , respectively, for interest and penalties. HP engages in continuous discussion and negotiation with taxing authorities regarding tax matters in various jurisdictions. While HP does not expect complete resolution of certain tax years with various tax authorities in the next 12 months , it is reasonably possible that its existing unrecognized tax benefits may be reduced by an immaterial amount within the next 12 months . HP is subject to income tax in the United States and approximately 58 other countries and is subject to routine corporate income tax audits in many of these jurisdictions. In addition, HP is subject to numerous ongoing audits by federal, state and foreign tax authorities. The IRS is conducting an audit of HP’s 2016 income tax return. With respect to major state and foreign tax jurisdictions, HP is no longer subject to tax authority examinations for years prior to 2002. No material tax deficiencies have been assessed in major state or foreign tax jurisdictions as of October 31, 2019. The U.S. Tax Court ruled in May 2012 against HP related to certain tax attributes claimed by HP for the tax years 1999 through 2003. HP appealed the U.S. Tax Court determination by filing a formal Notice of Appeal with the Ninth Circuit Court of Appeals. This case was argued before the Ninth Circuit in November 2016. The Ninth Circuit Court of Appeals issued its opinion in November 2017 affirming the Tax Court determinations. In fiscal year 2018, HP decided against further appeal. HP believes it has provided adequate reserves for all tax deficiencies or reductions in tax benefits that could result from federal, state and foreign tax audits. HP regularly assesses the likely outcomes of these audits in order to determine the appropriateness of HP’s tax provision. HP adjusts its uncertain tax positions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular audit. However, income tax audits are inherently unpredictable and there can be no assurance that HP will accurately predict the outcome of these audits. The amounts ultimately paid on resolution of an audit could be materially different from the amounts previously included in the Provision for taxes and therefore the resolution of one or more of these uncertainties in any particular period could have a material impact on net income or cash flows. HP has not provided for U.S. federal income and foreign withholding taxes on $5.7 billion of undistributed earnings from non-U.S. operations as of October 31, 2019 because HP intends to reinvest such earnings indefinitely outside of the United States. Determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable. The TCJA taxed HP’s historic earnings and profits of its non-U.S. subsidiaries. HP will remit these taxed reinvested earnings for which deferred U.S. federal and withholding taxes have been provided where excess cash has accumulated and HP determines that it is advantageous for business operations, tax or cash management reasons. Deferred Income Taxes The significant components of deferred tax assets and deferred tax liabilities were as follows: As of October 31 2019 2018 In millions Deferred Tax Assets Loss and credit carryforwards $ 7,856 $ 8,204 Intercompany transactions—excluding inventory 714 994 Fixed assets 115 151 Warranty 195 194 Employee and retiree benefits 396 401 Deferred Revenue 145 164 Capitalized research and development 193 — Intangible assets 420 — Other 556 422 Gross Deferred Tax Assets 10,590 10,530 Valuation allowances (7,930 ) (7,906 ) Total Deferred Tax Assets 2,660 2,624 Deferred Tax Liabilities Unremitted earnings of foreign subsidiaries (27 ) (31 ) Intangible assets — (229 ) Other (73 ) (33 ) Total Deferred Tax Liabilities (100 ) (293 ) Net Deferred Tax Assets $ 2,560 $ 2,331 Deferred tax assets and liabilities included in the Consolidated Balance Sheets as follows: As of October 31 2019 2018 In millions Deferred tax assets $ 2,620 $ 2,431 Deferred tax liabilities (60 ) (100 ) Total $ 2,560 $ 2,331 As of October 31, 2019, HP had recorded deferred tax assets for net operating loss carryforwards as follows: Gross NOLs Deferred Taxes on NOLs Valuation allowance Initial Year of Expiration In millions Federal $ 372 $ 78 $ (19 ) 2023 State 2,634 167 (62 ) 2019 Foreign 26,317 7,434 (7,357 ) 2021 Balance at end of year $ 29,323 $ 7,679 $ (7,438 ) As of October 31, 2019, HP had recorded deferred tax assets for various tax credit carryforwards as follows: Carryforward Valuation Initial In millions Tax credits in state and foreign jurisdictions $ 307 $ (42 ) 2021 Balance at end of year $ 307 $ (42 ) Deferred Tax Asset Valuation Allowance The deferred tax asset valuation allowance and changes were as follows: For the fiscal years ended October 31 2019 2018 2017 In millions Balance at beginning of year $ 7,906 $ 8,807 $ 8,520 Income tax (benefit) expense (339 ) (897 ) 297 Other comprehensive income, currency translation and charges to other accounts 363 (4 ) (10 ) Balance at end of year $ 7,930 $ 7,906 $ 8,807 Gross deferred tax assets as of October 31, 2019, 2018 and 2017 were reduced by valuation allowances of $7.9 billion , $7.9 billion and $8.8 billion , respectively. In fiscal year 2019, the deferred tax asset valuation allowance increased by $24 million primarily associated with the recognition of the income tax consequences of intra-entity transfers other than inventory, see Note 1, “Summary of Significant Accounting Policies” for detailed information. This increase was partially offset by the impact of tax rate changes in foreign jurisdictions and state valuation allowance releases. In fiscal year 2018, the deferred tax valuation allowance decreased by $901 million primarily associated with foreign net operating losses and U.S. deferred tax assets that are anticipated to be realized at a lower effective rate than the federal statutory tax rate due to certain future U.S. international tax reform implications. In fiscal year 2017, the deferred tax asset valuation allowance increased by $287 million primarily associated with foreign net operating losses.

These financing arrangements, which in certain circumstances may contain partial recourse, result in a transfer of HP’s receivables and risk, to the third-party. As these transfers qualify as true sales under the applicable accounting guidance, the receivables are de-recognized from the Consolidated Balance Sheets upon transfer, and HP receives a payment for the receivables from the third-party within a mutually agreed upon time period. For arrangements involving an element of recourse, the recourse obligation is measured using market data from the similar transactions and reported as a current liability in the Consolidated Balance Sheets. The recourse obligations as of October 31, 2019 and 2018 were not material. The costs associated with the sales of trade receivables for fiscal year 2019, 2018 and 2017 were not material. The following is a summary of the activity under these arrangements: For the fiscal years ended October 31 2019 2018 2017 In millions Balance at beginning of year (1) $ 165 $ 147 $ 149 Trade receivables sold 10,257 10,224 9,553 Cash receipts (10,186 ) (10,202 ) (9,562 ) Foreign currency and other (1 ) (4 ) 7 Balance at end of year (1) $ 235 $ 165 $ 147 (1) Amounts outstanding from third parties reported in Accounts Receivable in the Consolidated Balance Sheets.

See Note 15, “Guarantees, Indemnifications and Warranties” for further information. Net Revenue by Region For the fiscal years ended October 31 2019 2018 2017 In millions Americas $ 25,244 $ 25,644 $ 23,891 Europe, Middle East and Africa 20,275 20,470 17,507 Asia-Pacific and Japan 13,237 12,358 10,658 Total net revenue $ 58,756 $ 58,472 $ 52,056 Value of Remaining Performance Obligations As of October 31, 2019, the estimated value of transaction price allocated to remaining performance obligations was $4.4 billion . HP expects to recognize approximately $1.8 billion of the unearned amount in next 12 months and $2.6 billion thereafter. HP has elected the practical expedients and accordingly does not disclose the aggregate amount of the transaction price allocated to remaining performance obligations if: • the contract has an original expected duration of one year or less; or • the revenue from the performance obligation is recognized over time on an as-invoiced basis when the amount corresponds directly with the value to the customer; or • the portion of the transaction price that is variable in nature is allocated entirely to a wholly unsatisfied performance obligation. The remaining performance obligations are subject to change and may be affected by various factors, such as termination of contracts, contract modifications and adjustment for currency. Costs of Obtaining Contracts As of October 31, 2019, deferred contract fulfillment and acquisition costs balances were $47 million and $30 million , included in Other Current Assets and Other Non-Current Assets, respectively, in the Consolidated Balance Sheet. During the twelve months ended October 31, 2019, the Company amortized $108 million of these costs. Contract Liabilities As of October 31, 2019 and November 1, 2018, HP’s contract liabilities balances were $2.1 billion and $1.9 billion , included in Other Current Liabilities and Other Non-Current Liabilities, respectively, in the Consolidated Balance Sheet. The increase in the contract liabilities balance for fiscal year 2019 is primarily driven by sales of fixed price support and maintenance services, partially offset by $922 million of revenue recognized that were included in the opening contract liabilities balance as of November 1, 2018.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. Fair Value Hierarchy HP uses valuation techniques that are based upon observable and unobservable inputs. Observable inputs are developed using market data such as publicly available information and reflect the assumptions market participants would use, while unobservable inputs are developed using the best information available about the assumptions market participants would use. Assets and liabilities are classified in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement: Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2—Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market-corroborated inputs. Level 3—Unobservable inputs for the asset or liability. The fair value hierarchy gives the highest priority to observable inputs and lowest priority to unobservable inputs. The following table presents HP’s assets and liabilities that are measured at fair value on a recurring basis: As of October 31, 2019 As of October 31, 2018 Fair Value Measured Using Fair Value Measured Using Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total In millions Assets: Cash Equivalents: Corporate debt $ — $ 1,283 $ — $ 1,283 $ — $ 1,620 $ — $ 1,620 Financial institution instruments — — — — — 9 — 9 Government debt (1) 2,422 — — 2,422 2,217 150 — 2,367 Available-for-Sale Investments: Corporate debt — — — — — 366 — 366 Financial institution instruments — — — — — 32 — 32 Government debt (1) — — — — — 313 — 313 Marketable equity securities and Mutual funds 6 50 — 56 53 — — 53 Derivative Instruments: Interest rate contracts — 4 — 4 — — — — Foreign currency contracts — 381 — 381 — 508 7 515 Other derivatives — 7 — 7 — — — — Total Assets $ 2,428 $ 1,725 $ — $ 4,153 $ 2,270 $ 2,998 $ 7 $ 5,275 Liabilities: Derivative Instruments: Interest rate contracts $ — $ — $ — $ — $ — $ 23 $ — $ 23 Foreign currency contracts — 165 — 165 — 164 — 164 Other derivatives — 1 — 1 — 8 — 8 Total Liabilities $ — $ 166 $ — $ 166 $ — $ 195 $ — $ 195 (1) Government debt includes instruments such as U.S. treasury notes, U.S. agency securities and non-U.S. government bonds. Money market funds invested in government debt and trade in active markets are included in Level 1. Valuation Techniques Cash Equivalents and Investments: HP holds time deposits, money market funds, mutual funds, other debt securities primarily consisting of corporate and foreign government notes and bonds, and common stock and equivalents. HP values cash equivalents and equity investments using quoted market prices, alternative pricing sources, including net asset value, or models utilizing market observable inputs. The fair value of debt investments was based on quoted market prices or model-driven valuations using inputs primarily derived from or corroborated by observable market data, and, in certain instances, valuation models that utilize assumptions which cannot be corroborated with observable market data. Derivative Instruments: From time to time, HP uses forward contracts, interest rate and total return swaps and, in the past, option contracts to hedge certain foreign currency interest rate and return on certain investment exposures. HP uses industry standard valuation models to measure fair value. Where applicable, these models project future cash flows and discount the future amounts to present value using market-based observable inputs, including interest rate curves, HP and counterparty credit risk, foreign exchange rates, and forward and spot prices for currencies and interest rates. See Note 10, “Financial Instruments” for a further discussion of HP’s use of derivative instruments. Other Fair Value Disclosures Short- and Long-Term Debt: HP estimates the fair value of its debt primarily using an expected present value technique, which is based on observable market inputs using interest rates currently available to companies of similar credit standing for similar terms and remaining maturities, and considering its own credit risk. The portion of HP’s debt that is hedged is reflected in the Consolidated Balance Sheets as an amount equal to the debt’s carrying amount and a fair value adjustment representing changes in the fair value of the hedged debt obligations arising from movements in benchmark interest rates. The fair value of HP’s short- and long-term debt was $5.4 billion at October 31, 2019 compared to its carrying amount of $5.1 billion at that date. The fair value of HP’s short- and long-term debt was $6.0 billion as compared to its carrying value of $6.0 billion at October 31, 2018. If measured at fair value in the Consolidated Balance Sheets, short- and long-term debt would be classified in Level 2 of the fair value hierarchy. Other Financial Instruments: For the balance of HP’s financial instruments, primarily accounts receivable, accounts payable and financial liabilities included in other current liabilities on the Consolidated Balance Sheets, the carrying amounts approximate fair value due to their short maturities. If measured at fair value in the Consolidated Balance Sheets, these other financial instruments would be classified in Level 2 or Level 3 of the fair value hierarchy. Non-Marketable Equity Investments and Non-Financial Assets: HP’s non-marketable equity investments are measured at cost less impairment, adjusted for observable price changes. HP’s non-financial assets, such as intangible assets, goodwill and property, plant and equipment, are recorded at fair value in the period an impairment charge is recognized. If measured at fair value in the Consolidated Balance Sheets these would generally be classified within Level 3 of the fair value hierarchy.

All highly liquid investments with original maturities of three months or less at the date of acquisition are considered cash equivalents. As of October 31, 2019 and 2018, the carrying amount of cash equivalents approximated fair value due to the short period of time to maturity. Interest income related to cash, cash equivalents and debt securities was approximately $80 million in fiscal year 2019, $116 million in fiscal year 2018, and $66 million in fiscal year 2017. The estimated fair value of the available-for-sale investments may not be representative of values that will be realized in the future. Equity securities in privately held companies are included in Other non-current assets in the Consolidated Balance Sheets. These amounted to $46 million and $36 million as of October 31, 2019 and 2018, respectively. Derivative Instruments HP uses derivatives to offset business exposure to foreign currency and interest rate risk on expected future cash flows and on certain existing assets and liabilities. As part of its risk management strategy, HP uses derivative instruments, primarily forward contracts, interest rate swaps, total return swaps and, at times, option contracts to hedge certain foreign currency, interest rate and, return on certain investment exposures. HP may designate its derivative contracts as fair value hedges or cash flow hedges and classifies the cash flows with the activities that correspond to the underlying hedged items. Additionally, for derivatives not designated as hedging instruments, HP categorizes those economic hedges as other derivatives. HP recognizes all derivative instruments at fair value in the Consolidated Balance Sheets. As a result of its use of derivative instruments, HP is exposed to the risk that its counterparties will fail to meet their contractual obligations. Master netting agreements mitigate credit exposure to counterparties by permitting HP to net amounts due from HP to counterparty against amounts due to HP from the same counterparty under certain conditions. To further limit credit risk, HP has collateral security agreements that allow HP’s custodian to hold collateral from, or require HP to post collateral to, counterparties when aggregate derivative fair values exceed contractually established thresholds which are generally based on the credit ratings of HP and its counterparties. If HP’s or the counterparty’s credit rating falls below a specified credit rating, either party has the right to request full collateralization of the derivatives’ net liability position. The fair value of derivatives with credit contingent features in a net liability position was $45 million and $68 million as of October 31, 2019 and 2018, respectively, all of which were fully collateralized within two business days. Under HP’s derivative contracts, the counterparty can terminate all outstanding trades following a covered change of control event affecting HP that results in the surviving entity being rated below a specified credit rating. This credit contingent provision did not affect HP’s financial position or cash flows as of October 31, 2019 and 2018. Fair Value Hedges HP enters into fair value hedges, such as interest rate swaps, to reduce the exposure of its debt portfolio to changes in fair value resulting from changes in interest rates by achieving a primarily U.S. dollar London Interbank Offered Rate (“LIBOR”)-based floating interest expense. For derivative instruments that are designated and qualify as fair value hedges, HP recognizes the change in fair value of the derivative instrument, as well as the offsetting change in the fair value of the hedged item, in Interest and other, net in the Consolidated Statements of Earnings in the period of change. Cash Flow Hedges HP uses forward contracts and at times, option contracts designated as cash flow hedges to protect against the foreign currency exchange rate risks inherent in its forecasted net revenue and, to a lesser extent, cost of revenue and operating expenses. HP’s foreign currency cash flow hedges mature predominantly within twelve months ; however, hedges related to long-term procurement arrangements extend several years. For derivative instruments that are designated and qualify as cash flow hedges, HP initially records changes in fair value for the effective portion of the derivative instrument in Accumulated other comprehensive loss as a separate component of stockholders’ deficit in the Consolidated Balance Sheets and subsequently reclassifies these amounts into earnings in the period during which the hedged transaction is recognized in earnings. HP reports the effective portion of its cash flow hedges in the same financial statement line item as changes in the fair value of the hedged item. Other Derivatives Other derivatives not designated as hedging instruments consist primarily of forward contracts used to hedge foreign currency-denominated balance sheet exposures. HP uses total return swaps to hedge its executive deferred compensation plan liability. For derivative instruments not designated as hedging instruments, HP recognizes changes in fair value of the derivative instrument, as well as the offsetting change in the fair value of the hedged item, in Interest and other, net in the Consolidated Statements of Earnings in the period of change. Hedge Effectiveness For interest rate swaps designated as fair value hedges, HP measures hedge effectiveness by offsetting the change in fair value of the hedged item with the change in fair value of the derivative. For foreign currency options and forward contracts designated as cash flow hedges, HP measures hedge effectiveness by comparing the cumulative change in fair value of the hedge contract with the cumulative change in fair value of the hedged item, both of which are based on forward rates. HP recognizes any ineffective portion of the hedge in the Consolidated Statements of Earnings in the same period in which ineffectiveness occurs. Amounts excluded from the assessment of effectiveness are recognized in the Consolidated Statements of Earnings in the period they arise. Fair Value of Derivative Instruments in the Consolidated Balance Sheets The gross notional and fair value of derivative instruments in the Consolidated Balance Sheets was as follows: As of October 31, 2019 As of October 31, 2018 Outstanding Gross Notional Other Current Assets Other Non-Current Assets Other Current Liabilities Other Non-Current Liabilities Outstanding Gross Notional Other Current Assets Other Non-Current Assets Other Current Liabilities Other Non-Current Liabilities In millions Derivatives designated as hedging instruments Fair value hedges: Interest rate contracts $ 750 $ — $ 4 $ — $ — $ 1,000 $ — $ — $ — $ 23 Cash flow hedges: Foreign currency contracts 15,639 260 111 123 28 17,147 386 107 86 52 Total derivatives designated as hedging instruments 16,389 260 115 123 28 18,147 386 107 86 75 Derivatives not designated as hedging instruments Foreign currency contracts 7,146 10 — 14 — 5,437 22 — 26 — Other derivatives 134 7 — 1 — 122 — — 8 — Total derivatives not designated as hedging instruments 7,280 17 — 15 — 5,559 22 — 34 — Total derivatives $ 23,669 $ 277 $ 115 $ 138 $ 28 $ 23,706 $ 408 $ 107 $ 120 $ 75 Offsetting of Derivative Instruments HP recognizes all derivative instruments on a gross basis in the Consolidated Balance Sheets. HP does not offset the fair value of its derivative instruments against the fair value of cash collateral posted under its collateral security agreements. As of October 31, 2019 and 2018, information related to the potential effect of HP’s master netting agreements and collateral security agreements was as follows: In the Consolidated Balance Sheets (i) (ii) (iii) = (i)–(ii) (iv) (v) (vi) = (iii)–(iv)–(v) Gross Amount Recognized Gross Amount Offset Net Amount Presented Gross Amounts Not Offset Derivatives Financial Collateral Net Amount In millions As of October 31, 2019 Derivative assets $ 392 $ — $ 392 $ 113 $ 259 (1) $ 20 Derivative liabilities $ 166 $ — $ 166 $ 113 $ 43 (2) $ 10 As of October 31, 2018 Derivative assets $ 515 $ — $ 515 $ 112 $ 299 (1) $ 104 Derivative liabilities $ 195 $ — $ 195 $ 112 $ 69 (2) $ 14 (1) Represents the cash collateral posted by counterparties as of the respective reporting date for HP’s asset position, net of derivative amounts that could be offset, as of, generally, two business days prior to the respective reporting date. (2) Represents the collateral posted by HP through re-use of counterparty cash collateral as of the respective reporting date for HP’s liability position, net of derivative amounts that could be offset, as of, generally, two business days prior to the respective reporting date. Effect of Derivative Instruments on the Consolidated Statements of Earnings The pre-tax effect of derivative instruments and related hedged items in a fair value hedging relationship for fiscal years ended October 31, 2019, 2018 and 2017 was as follows: Gain (Loss) Recognized in Income on Derivative Instruments and Related Hedged Items Derivative Instrument Location 2019 2018 2017 Hedged Item Location 2019 2018 2017 In millions In millions Interest rate contracts Interest and other, net $ 27 $ (11 ) $ (60 ) Fixed-rate debt Interest and other, net $ (27 ) $ 11 $ 60 The pre-tax effect of derivative instruments in cash flow hedging relationships for fiscal years ended October 31, 2019, 2018 and 2017 was as follows: Gain (Loss) Recognized in OCI Gain (Loss) Reclassified from Accumulated OCI 2019 2018 2017 2019 2018 2017 In millions In millions Cash flow hedges: Foreign currency contracts $ 252 $ 341 $ (651 ) Net revenue $ 425 $ (239 ) $ (156 ) Cost of revenue (43 ) (18 ) (35 ) Other operating expenses (2 ) (1 ) 1 Interest and other, net — — (9 ) Total $ 252 $ 341 $ (651 ) Total $ 380 $ (258 ) $ (199 ) As of October 31, 2019, 2018 and 2017, no portion of the hedging instruments’ gain or loss was excluded from the assessment of effectiveness for fair value or cash flow hedges. Hedge ineffectiveness for fair value and cash flow hedges was not material for fiscal years 2019, 2018 and 2017. As of October 31, 2019, HP expects to reclassify an estimated accumulated other comprehensive income of approximately $104 million , net of taxes, to earnings within the next twelve months associated with cash flow hedges along with the earnings effects of the related forecasted transactions. The amounts ultimately reclassified into earnings could be different from the amounts previously included in accumulated OCI based on the change of market rate, and therefore could have different impact on earnings. The pre-tax effect of derivative instruments not designated as hedging instruments recognized in Interest and other, net in the Consolidated Statements of Earnings for fiscal years 2019, 2018 and 2017 was as follows: (Loss) Gain Recognized in Income on Derivatives Location 2019 2018 2017 In millions Foreign currency contracts Interest and other, net $ (119 ) $ 35 $ (32 ) Other derivatives Interest and other, net 14 (9 ) 3 Total $ (105 ) $ 26 $ (29 )

The U.S. Dollar Global Notes are senior unsecured debt . In December 2016, HP filed a shelf registration statement (the “2016 Shelf Registration Statement”) with the SEC to enable the company to offer for sale, from time to time, in one or more offerings, an unspecified amount of debt securities, common stock, preferred stock, depositary shares and warrants. As disclosed in Note 10, “Financial Instruments”, HP uses interest rate swaps to mitigate some of the exposure of its debt portfolio to changes in fair value resulting from changes in interest rates by achieving a primarily U.S. dollar LIBOR-based floating interest expense. Interest rates shown in the table of long-term debt have not been adjusted to reflect the impact of any interest rate swaps. As of October 31, 2019, aggregate future maturities of debt at face value (excluding unamortized debt issuance cost of $16 million and discounts on debt issuance of $2 million less fair value adjustment related to hedged debt of $4 million ), including capital lease obligations were as follows: Fiscal year In millions 2020 $ 357 2021 251 2022 2,015 2023 1,273 2024 42 Thereafter 1,213 Total $ 5,151 Extinguishment of Debt In March 2018, HP commenced and completed a cash tender offer (the “Tender Offer") to purchase approximately $1.85 billion in aggregate principal amount of outstanding U.S. Dollar 4.650% Global Notes due December 9, 2021, 4.375% Global Notes due September 15, 2021 and 4.300% Global Notes due June 1, 2021. In connection with the Tender Offer, HP also solicited consents from holders of its 4.650% Notes due December 2021, (the “ 4.650% Notes”) to amend the indenture under which the 4.650% Notes were issued to, among other things, eliminate substantially all of the restrictive covenants of the indenture (the “Proposed Amendments”). Holders of a majority in principal amount of the outstanding 4.650% Notes consented to the Proposed Amendments, and as a result, a supplemental indenture was executed on March 26, 2018 to effect the Proposed Amendments. This extinguishment of debt resulted in a loss of $126 million , which was recorded as "Interest and other, net" on the Consolidated Statements of Earnings for the year ended October 31, 2018. Commercial Paper As of October 31, 2019, HP maintained two commercial paper programs. HP’s U.S. program provides for the issuance of U.S. dollar-denominated commercial paper up to a maximum aggregate principal amount of $6.0 billion . HP’s euro commercial paper program provides for the issuance of commercial paper outside of the United States denominated in U.S. dollars, euros or British pounds up to a maximum aggregate principal amount of $6.0 billion or the equivalent in those alternative currencies. The combined aggregate principal amount of commercial paper outstanding under those programs at any one time cannot exceed the $6.0 billion authorized by HP’s Board of Directors. Credit Facility As of October 31, 2019, HP maintained a $4.0 billion senior unsecured committed revolving credit facility to support the issuance of commercial paper or for general corporate purposes. Commitments under the revolving credit facility will be available until March 30, 2023. Commitment fees, interest rates and other terms of borrowing under the credit facilities vary based on HP’s external credit ratings. As of October 31, 2019, HP was in compliance with the financial covenants in the credit agreement governing the revolving credit facility. Available Borrowing Resources As of October 31, 2019, HP and HP’s subsidiaries had available borrowing resources of $724 million from uncommitted lines of credit in addition to the senior unsecured committed revolving credit facility discussed above.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share HP calculates basic net EPS using net earnings and the weighted-average number of shares outstanding during the reporting period. Diluted net EPS includes any dilutive effect of restricted stock units, stock options, performance-based awards and shares purchased under the 2011 employee stock purchase plan. A reconciliation of the number of shares used for basic and diluted net EPS calculations is as follows: For the fiscal years ended October 31 2019 2018 2017 In millions, except per share amounts Numerator: Net earnings $ 3,152 $ 5,327 $ 2,526 Denominator: Weighted-average shares used to compute basic net EPS 1,515 1,615 1,688 Dilutive effect of employee stock plans 9 19 14 Weighted-average shares used to compute diluted net EPS 1,524 1,634 1,702 Net earnings per share: Basic $ 2.08 $ 3.30 $ 1.50 Diluted $ 2.07 $ 3.26 $ 1.48 Anti-dilutive weighted-average stock-based compensation awards (1) 7 — 1 (1) HP excludes from the calculation of diluted net EPS stock options and restricted stock units where the assumed proceeds exceed the average market price, because their effect would be anti-dilutive. The assumed proceeds of a stock option include the sum of its exercise price, and average unrecognized compensation cost. The assumed proceeds of a restricted stock unit represent unrecognized compensation cost.

Loss Contingency [Abstract]
Litigation and Contingencies	Litigation and Contingencies HP is involved in lawsuits, claims, investigations and proceedings, including those identified below, consisting of IP, commercial, securities, employment, employee benefits and environmental matters that arise in the ordinary course of business. HP accrues a liability when management believes that it is both probable that a liability has been incurred and the amount of loss can be reasonably estimated. HP believes it has recorded adequate provisions for any such matters and, as of October 31, 2019, it was not reasonably possible that a material loss had been incurred in excess of the amounts recognized in HP’s financial statements. HP reviews these matters at least quarterly and adjusts its accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Pursuant to the separation and distribution agreement, HP shares responsibility with Hewlett Packard Enterprise for certain matters, as indicated below, and Hewlett Packard Enterprise has agreed to indemnify HP in whole or in part with respect to certain matters. Based on its experience, HP believes that any damage amounts claimed in the specific matters discussed below are not a meaningful indicator of HP’s potential liability. Litigation is inherently unpredictable. However, HP believes it has valid defenses with respect to legal matters pending against it. Nevertheless, cash flows or results of operations could be materially affected in any particular period by the resolution of one or more of these contingencies. Litigation, Proceedings and Investigations Copyright Levies . Proceedings are ongoing or have been concluded involving HP in certain European countries, including litigation in Belgium and other countries, seeking to impose or modify levies upon IT equipment (such as multifunction devices (“MFDs”) and PCs), alleging that these devices enable the production of private copies of copyrighted materials. The levies are generally based upon the number of products sold and the per-product amounts of the levies, which vary. Some European countries that do not yet have levies on digital devices are expected to implement similar legislation to enable them to extend existing levy schemes, while other European countries have phased out levies or are expected to limit the scope of levy schemes and applicability in the digital hardware environment, particularly with respect to sales to business users. HP, other companies and various industry associations have opposed the extension of levies to the digital environment and have advocated alternative models of compensation to rights holders. Reprobel, a collecting society administering the remuneration for reprography to Belgian copyright holders, requested by extrajudicial means that HP amend certain copyright levy declarations submitted for inkjet MFDs sold in Belgium from January 2005 to December 2009 to enable it to collect copyright levies calculated based on the generally higher copying speed when the MFDs are operated in draft print mode rather than when operated in normal print mode. In March 2010, HP filed a lawsuit against Reprobel in the Court of First Instance of Brussels seeking a declaratory judgment that no copyright levies are payable on sales of MFDs in Belgium or, alternatively, that payments already made by HP are sufficient to comply with its obligations. The Court of Appeal in Brussels (the “Court of Appeal”) stayed the proceedings and referred several questions to the Court of Justice of the European Union (“CJEU”). On November 12, 2015, the CJEU published its judgment providing that a national legislation such as the Belgian one at issue in the main proceedings is incompatible with EU law on multiple legal points, as argued by HP, and returned the proceedings to the referring court. On May 12, 2017, the Court of Appeal held that (1) reprographic copyright levies are due notwithstanding the lack of conformity of the Belgian system with EU law in certain aspects and (2) the applicable levies are to be calculated based on the objective speed of each MFD as established by an expert appointed by the Court of Appeal. HP appealed this decision before the Belgian Supreme Court on January 18, 2018. Based on industry opposition to the extension of levies to digital products, HP’s assessments of the merits of various proceedings and HP’s estimates of the number of units impacted and the amounts of the levies, HP has accrued amounts that it believes are adequate to address the ongoing disputes. Hewlett-Packard Company v. Oracle Corporation . On June 15, 2011, HP filed suit against Oracle Corporation (“Oracle”) in California Superior Court in Santa Clara County in connection with Oracle’s March 2011 announcement that it was discontinuing software support for HP’s Itanium-based line of mission critical servers. HP asserted, among other things, that Oracle’s actions breached the contract that was signed by the parties as part of the settlement of the litigation relating to Oracle’s hiring of Mark Hurd. The matter eventually progressed to trial, which was bifurcated into two phases. HP prevailed in the first phase of the trial, in which the court ruled that the contract at issue required Oracle to continue to offer its software products on HP’s Itanium-based servers for as long as HP decided to sell such servers. The second phase of the trial was then postponed by Oracle’s appeal of the trial court’s denial of Oracle’s “anti-SLAPP” motion, in which Oracle argued that HP’s damages claim infringed on Oracle’s First Amendment rights. On August 27, 2015, the California Court of Appeals rejected Oracle’s appeal. The matter was remanded to the trial court for the second phase of the trial, which began on May 23, 2016 and was submitted to the jury on June 29, 2016. On June 30, 2016, the jury returned a verdict in favor of HP, awarding HP approximately $3.0 billion in damages, which included approximately $1.7 billion for past lost profits and $1.3 billion for future lost profits. On October 20, 2016, the court entered judgment for HP for this amount with interest accruing until the judgment is paid. Oracle’s motion for new trial was denied on December 19, 2016, and Oracle filed its notice of appeal from the trial court’s judgment on January 17, 2017. On February 2, 2017, HP filed a notice of cross-appeal challenging the trial court’s denial of prejudgment interest. The case is fully briefed and awaiting the Court of Appeals to schedule oral argument. HP expects that the appeals process could take several years to complete. Litigation is unpredictable, and there can be no assurance that HP will recover damages, or that any award of damages will be for the amount awarded by the jury’s verdict. The amount ultimately awarded, if any, would be recorded in the period received. No adjustment has been recorded in the financial statements in relation to this potential award. Pursuant to the terms of the separation and distribution agreement, HP and Hewlett Packard Enterprise will share equally in any recovery from Oracle once Hewlett Packard Enterprise has been reimbursed for all costs incurred in the prosecution of the action prior to the Separation. Forsyth, et al. vs. HP Inc. and Hewlett Packard Enterprise . This is a purported class and collective action filed on August 18, 2016 in the United States District Court, Northern District of California, against HP and Hewlett Packard Enterprise alleging the defendants violated the Federal Age Discrimination in Employment Act (“ADEA”), the California Fair Employment and Housing Act, California public policy and the California Business and Professions Code by terminating older workers and replacing them with younger workers. Plaintiffs seek to certify a nationwide collective class action under the ADEA comprised of all U.S. residents employed by defendants who had their employment terminated pursuant to a workforce reduction (“WFR”) plan on or after May 23, 2012 and who were 40 years of age or older. Plaintiffs also seek to represent a Rule 23 class under California law comprised of all persons 40 years or older employed by defendants in the state of California and terminated pursuant to a WFR plan on or after May 23, 2012. Following a partial motion to dismiss, a motion to strike and a motion to compel arbitration that the defendants filed in November 2016, the plaintiffs amended their complaint. New plaintiffs were added, but the plaintiffs agreed that the class period for the nationwide collective action should be shortened and now starts on December 9, 2014. On January 30, 2017, the defendants filed another partial motion to dismiss and motions to compel arbitration as to several of the plaintiffs. On March 20, 2017, the defendants filed additional motions to compel arbitration as to a number of the opt-in plaintiffs. On September 20, 2017, the Court granted the motions to compel arbitration as to the plaintiffs and opt-ins who signed WFR release agreements, and also stayed the entire case until the arbitrations are completed. On November 30, 2017, three named plaintiffs and twelve opt-in plaintiffs filed a single arbitration demand. An additional arbitration claimant was added later by stipulation. On December 22, 2017, the defendants filed a motion to (1) stay the case pending arbitrations and (2) enjoin the demanded arbitration and require each plaintiff to file a separate arbitration demand. On February 6, 2018, the Court granted the motion to stay and denied the motion to enjoin. Pre-arbitration mediation proceedings took place on October 4 and 5, 2018, and the claims of all 16 arbitration claimants were resolved. Between November 2018 and April 2019, an additional 154 individuals filed consents to opt‐in to the action as party‐plaintiffs. Of the new opt-ins, 145 signed separation agreements that include class waivers and mandatory arbitration provisions. The addition of these opt-ins brings the total number of named and opt-in plaintiffs to 193 . Mediation proceedings took place in June 2019 with respect to the 145 opt-ins who signed separation agreements, and the parties are continuing to engage in settlement discussions. The stay of the litigation remains in place. Jackson, et al. v. HP Inc. and Hewlett Packard Enterprise. This putative nationwide class action was filed on July 24, 2017 in federal district court in San Jose, California. The plaintiffs purport to bring the lawsuit on behalf of themselves and other similarly situated African-Americans and individuals over the age of 40 . The plaintiffs allege that the defendants engaged in a pattern and practice of racial and age discrimination in lay-offs and promotions. The plaintiffs filed an amended complaint on September 29, 2017. On January 12, 2018, the defendants moved to transfer the matter to the federal district court in the Northern District of Georgia. The defendants also moved to dismiss the claims on various grounds and to strike certain aspects of the proposed class definition. The Court dismissed the action on the basis of improper venue. On July 23, 2018, the plaintiffs refiled the case in the Northern District of Georgia. On August 9, 2018, the plaintiffs also filed a notice of appeal of the dismissal order with the United States Court of Appeals for the Ninth Circuit. On October 1, 2018, the Georgia court granted the plaintiffs’ unopposed motion to stay and administratively close the Georgia action until the Ninth Circuit appeal is decided. India Directorate of Revenue Intelligence Proceedings. On April 30 and May 10, 2010, the India Directorate of Revenue Intelligence (the “DRI”) issued show cause notices to Hewlett-Packard India Sales Private Limited (“HP India”), a subsidiary of HP, seven HP India employees and one former HP India employee alleging that HP India underpaid customs duties while importing products and spare parts into India and seeking to recover an aggregate of approximately $370 million , plus penalties. Prior to the issuance of the show cause notices, HP India deposited approximately $16 million with the DRI and agreed to post a provisional bond in exchange for the DRI’s agreement to not seize HP India products and spare parts and to not interrupt the transaction of business by HP India. On April 11, 2012, the Bangalore Commissioner of Customs issued an order on the products-related show cause notice affirming certain duties and penalties against HP India and the named individuals of approximately $386 million , of which HP India had already deposited $9 million . On December 11, 2012, HP India voluntarily deposited an additional $10 million in connection with the products-related show cause notice. The differential duty demand is subject to interest. On April 20, 2012, the Commissioner issued an order on the parts-related show cause notice affirming certain duties and penalties against HP India and certain of the named individuals of approximately $17 million , of which HP India had already deposited $7 million . After the order, HP India deposited an additional $3 million in connection with the parts-related show cause notice so as to avoid certain penalties. HP India filed appeals of the Commissioner’s orders before the Customs Tribunal along with applications for waiver of the pre-deposit of remaining demand amounts as a condition for hearing the appeals. The Customs Department has also filed cross-appeals before the Customs Tribunal. On January 24, 2013, the Customs Tribunal ordered HP India to deposit an additional $24 million against the products order, which HP India deposited in March 2013. The Customs Tribunal did not order any additional deposit to be made under the parts order. In December 2013, HP India filed applications before the Customs Tribunal seeking early hearing of the appeals as well as an extension of the stay of deposit as to HP India and the individuals already granted until final disposition of the appeals. On February 7, 2014, the application for extension of the stay of deposit was granted by the Customs Tribunal until disposal of the appeals. On October 27, 2014, the Customs Tribunal commenced hearings on the cross-appeals of the Commissioner’s orders. The Customs Tribunal rejected HP India’s request to remand the matter to the Commissioner on procedural grounds. The hearings scheduled to reconvene on April 6, 2015 and again on November 3, 2015 and April 11, 2016 were canceled at the request of the Customs Tribunal. A hearing on the merits of the appeal scheduled for January 15, 2019 has been cancelled. Pursuant to the separation and distribution agreement, Hewlett Packard Enterprise has agreed to indemnify HP in part, based on the extent to which any liability arises from the products and spare parts of Hewlett Packard Enterprise’s businesses. Neodron Patent Litigation . United States. On May 21, 2019, Neodron Ltd. (“Neodron”) filed a patent infringement lawsuit against Hewlett Packard Enterprise in U.S. District Court for the Western District of Texas. On the same day, Neodron filed a companion complaint with the U.S. International Trade Commission (“ITC”) pursuant to Section 337 of the Tariff Act of 1930 against seven sets of respondents, including Hewlett Packard Enterprise. On May 23 and June 14, 2019, Neodron filed amended complaints in the ITC and the Western District of Texas, respectively, to replace Hewlett Packard Enterprise with HP. Both complaints allege that certain touch-controlled devices infringe four patents owned by Neodron. On June 19, 2019, the ITC instituted an investigation. The ITC hearing is scheduled to begin on March 23, 2020, and the ITC’s target date for completion of the investigation is October 26, 2020. The district court action is stayed pending resolution of the ITC proceedings. In the ITC proceeding, Neodron seeks an order enjoining HP from importing, selling for importation, or selling after importation certain touch-controlled notebook computers and tablets. On June 28, 2019, Neodron filed a second lawsuit in the Western District of Texas, asserting four additional patents against HP touch-controlled devices. Neodron amended its complaint in the second lawsuit to assert a total of eight patents against HP touch-controlled devices. Neodron seeks unspecified damages and a permanent injunction, among other remedies. Germany. On October 29, 2019, Neodron served HP with a claim of patent infringement at the Munich State Court in Germany. The patent asserted in the German case is related to a patent asserted in the ITC. This case will consist of an initial hearing in March 2020 and formal hearing in late 2020. If the German court finds infringement of a valid patent, the court may issue an injunction as part of any remedy. Slingshot Printing LLC Litigation . On June 11, 2019, Slingshot Printing LLC filed three complaints in U.S. District Court in the Western District of Texas alleging HP infringes or has infringed sixteen patents. On September 20, 2019, Slingshot filed a four th complaint and amended the three earlier complaints, alleging that HP infringes or has infringed thirty-two patents. The accused products include inkjet printers, cartridges, and printheads. The complaints seek monetary damages. Parziale v. HP, Inc . On August 27, 2019, a purported consumer class action was filed against HP arising out of the supplies authentication protocol in certain OfficeJet printers. The complaint, which was filed in the United States District Court for the Northern District of California, captioned Parziale v. HP, Inc., alleges two causes of action under Florida Consumer Protection statutes: (1) violation of the Florida Deceptive and Unfair Trade Practices Act, F.S.A. §§ 501.201 et seq., and (2) violation of the Florida Misleading Advertisement Law, F.S.A. §§ 817.41 et seq. The named plaintiff, a Florida resident who purchased OfficeJet printers in Florida, seeks to represent a nationwide class of “[a]ll United States Citizens who, between the applicable statute of limitations and the present, had an HP Printer that was modified to reject third party ink cartridges or refilled HP ink cartridges.” On October 30, 2019, HP moved to dismiss the complaint. On November 13, 2019, plaintiff filed an amended complaint, adding the following new causes of action to the case: (1) violation of the Computer Fraud and Abuse Act, 18 U.S.C. § 1030 et seq., (2) trespass to chattels, and (3) tortious interference with business relations. Autonomy-Related Legal Matters Investigations. As a result of the findings of an ongoing investigation, HP has provided information to the U.K. Serious Fraud Office, the U.S. Department of Justice (“DOJ”) and the SEC related to the accounting improprieties, disclosure failures and misrepresentations at Autonomy that occurred prior to and in connection with HP’s acquisition of Autonomy. On January 19, 2015, the U.K. Serious Fraud Office notified HP that it was closing its investigation and had decided to cede jurisdiction of the investigation to the U.S. authorities. On November 14, 2016, the DOJ announced that a federal grand jury indicted Sushovan Hussain, the former CFO of Autonomy. Mr. Hussain was charged with conspiracy to commit wire fraud, securities fraud, and multiple counts of wire fraud. The indictment alleged that Mr. Hussain engaged in a scheme to defraud purchasers and sellers of securities of Autonomy and HP about the true performance of Autonomy’s business, its financial condition, and its prospects for growth. A jury trial commenced on February 26, 2018. On April 30, 2018, the jury found Mr. Hussain guilty of all charges against him. On November 15, 2016, the SEC announced that Stouffer Egan, the former CEO of Autonomy’s U.S.-based operations, settled charges relating to his participation in an accounting scheme to meet internal sales targets and analyst revenue expectations. On November 29, 2018, the DOJ announced that a federal grand jury indicted Michael Lynch, former CEO of Autonomy, and Stephen Chamberlain, former VP of Finance of Autonomy. Dr. Lynch and Mr. Chamberlain were charged with conspiracy to commit wire fraud and multiple counts of wire fraud. HP is continuing to cooperate with the ongoing enforcement actions. Autonomy Corporation Limited v. Michael Lynch and Sushovan Hussain. On April 17, 2015, four former HP subsidiaries that became subsidiaries of Hewlett Packard Enterprise at the time of the Separation (Autonomy Corporation Limited, Hewlett Packard Vision BV, Autonomy Systems, Limited, and Autonomy, Inc.) initiated civil proceedings in the U.K. High Court of Justice against two members of Autonomy’s former management, Michael Lynch and Sushovan Hussain. The Particulars of Claim seek damages in excess of $5 billion from Messrs. Lynch and Hussain for breach of their fiduciary duties by causing Autonomy group companies to engage in improper transactions and accounting practices. On October 1, 2015, Messrs. Lynch and Hussain filed their defenses. Mr. Lynch also filed a counterclaim against Autonomy Corporation Limited seeking $160 million in damages, among other things, for alleged misstatements regarding Lynch. The Hewlett Packard Enterprise subsidiary claimants filed their replies to the defenses and the asserted counter-claim on March 11, 2016. The parties are actively engaged in the disclosure process. Trial began on March 25, 2019 and is scheduled to continue through the remainder of 2019. Environmental HP’s business is subject to various federal, state, local and foreign laws and regulations that could result in costs or other sanctions that adversely affect our business and results of operations. For example, HP is subject to laws and regulations concerning environmental protection, including laws addressing the discharge of pollutants into the air and water, the management and disposal of hazardous substances and wastes, the clean-up of contaminated sites, the content of HP’s products and the recycling, treatment and disposal of those products, including batteries. In particular, HP faces increasing complexity in its product design and procurement operations as it adjusts to new and future requirements relating to the chemical and materials composition of its products, their safe use, the energy consumption associated with those products, climate change laws and regulations, and product repairability, reuse and take-back legislation. HP could incur substantial costs, its products could be restricted from entering certain jurisdictions, and it could face other sanctions, if it were to violate or become liable under environmental laws or if its products become noncompliant with environmental laws. HP’s potential exposure includes fines and civil or criminal sanctions, third-party property damage or personal injury claims and clean-up costs. The amount and timing of costs to comply with environmental laws are difficult to predict. HP is party to, or otherwise involved in, proceedings brought by U.S. or state environmental agencies under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), known as “Superfund,” or state laws similar to CERCLA, and may become a party to, or otherwise involved in, proceedings brought by private parties for contribution towards clean-up costs. HP is also conducting environmental investigations or remediations at several current or former operating sites pursuant to administrative orders or consent agreements with state environmental agencies. The separation and distribution agreement includes provisions that provide for the allocation of environmental liabilities between HP and Hewlett Packard Enterprise including certain remediation obligations; responsibilities arising from the chemical and materials composition of their respective products, their safe use and their energy consumption; obligations under product take back legislation that addresses the collection, recycling, treatment and disposal of products; and other environmental matters. HP will generally be responsible for environmental liabilities related to the properties and other assets, including products, allocated to HP under the separation and distribution agreement and other ancillary agreements. Under these agreements, HP will indemnify Hewlett Packard Enterprise for liabilities for specified ongoing remediation projects, subject to certain limitations, and Hewlett Packard Enterprise has a payment obligation for a specified portion of the cost of those remediation projects. In addition, HP will share with Hewlett Packard Enterprise other environmental liabilities as set forth in the separation and distribution agreement. HP is indemnified in whole or in part by Hewlett Packard Enterprise for liabilities arising from the assets assigned to Hewlett Packard Enterprise and for certain environmental matters as detailed in the separation and distribution agreement.

Guarantees and Product Warranties [Abstract]
Guarantees, Indemnifications and Warranties	Guarantees, Indemnifications and Warranties Guarantees In the ordinary course of business, HP may issue performance guarantees to certain of its clients, customers and other parties pursuant to which HP has guaranteed the performance obligations of third parties. Some of those guarantees may be backed by standby letters of credit or surety bonds. In general, HP would be obligated to perform over the term of the guarantee in the event a specified triggering event occurs as defined by the guarantee. HP believes the likelihood of having to perform under a material guarantee is remote. Cross-Indemnifications with Hewlett Packard Enterprise Under the separation and distribution agreement, HP agreed to indemnify Hewlett Packard Enterprise, each of its subsidiaries and each of their respective directors, officers and employees from and against all liabilities relating to, arising out of or resulting from, among other matters, the liabilities allocated to HP as part of the Separation. Hewlett Packard Enterprise similarly agreed to indemnify HP, each of its subsidiaries and each of their respective directors, officers and employees from and against all liabilities relating to, arising out of or resulting from, among other matters, the liabilities allocated to Hewlett Packard Enterprise as part of the Separation. HP expects Hewlett Packard Enterprise to fully perform under the terms of the separation and distribution agreement. For information on cross-indemnifications with Hewlett Packard Enterprise for litigation matters, see Note 14, “Litigation and Contingencies”. In connection with the Separation, HP entered into the TMA with Hewlett Packard Enterprise, effective on November 1, 2015. The TMA provided that HP and Hewlett Packard Enterprise will share certain pre-Separation income tax liabilities. The TMA was terminated during the fourth quarter of fiscal year 2019. Indemnifications In the ordinary course of business, HP enters into contractual arrangements under which HP may agree to indemnify a third party to such arrangement from any losses incurred relating to the services they perform on behalf of HP or for losses arising from certain events as defined within the particular contract, which may include, for example, litigation or claims relating to past performance. HP also provides indemnifications to certain vendors and customers against claims of intellectual property infringement made by third parties arising from the vendors’ and customers’ use of HP’s software products and services and certain other matters. Some indemnifications may not be subject to maximum loss clauses. Historically, payments made related to these indemnifications have been immaterial. HP records tax indemnification receivables from various third parties for certain tax liabilities that HP is jointly and severally liable for, but for which it is indemnified by those same third parties under existing legal agreements. HP records a tax indemnification payable to various third parties under these agreements when management believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. The actual amount that the parties pay or may be obligated to pay could vary depending on the outcome of certain unresolved tax matters, which may not be resolved for several years. The net payable and net receivable as of October 31, 2019 and October 31, 2018 were $57 million and $1.0 billion , respectively. During fiscal year 2019, $1.0 billion of indemnification receivables was reduced primarily due to resolution of various tax matters amounting to $0.8 billion . Warranties HP accrues the estimated cost of product warranties at the time it recognizes revenue. HP engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers; however, contractual warranty terms, repair costs, product call rates, average cost per call, current period product shipments and ongoing product failure rates, as well as specific product class failures outside of HP’s baseline experience, affect the estimated warranty obligation. HP’s aggregate product warranty liabilities and changes were as follows: For the fiscal years ended October 31 2019 2018 In millions Balance at beginning of year $ 915 $ 898 Accruals for warranties issued 1,051 1,042 Adjustments related to pre-existing warranties (including changes in estimates) (3 ) (15 ) Settlements made (in cash or in kind) (1,041 ) (1,010 ) Balance at end of year $ 922 $ 915

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Oct. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements of HP and its wholly-owned subsidiaries are prepared in conformity with U.S. GAAP.
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of HP and its subsidiaries and affiliates in which HP has a controlling financial interest or is the primary beneficiary. All intercompany balances and transactions have been eliminated.
Reclassifications	Reclassifications Effective at the beginning of its first quarter of fiscal year 2019, HP implemented an organizational change to align its business unit financial reporting more closely with its current business structure. HP reflected this change to its business unit information in prior reporting periods on an as-if basis. The reporting change had no impact to previously reported segment net revenue, consolidated net revenue, earnings from operations, net earnings or net EPS. HP has reclassified certain prior-year amounts to conform to the current-year presentation as a result of the adoption of Accounting Standards Update (“ASU”) 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. This adoption had no impact on previously reported consolidated net revenue, net earnings or net EPS.
Use of Estimates	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 HP’s Consolidated Financial Statements and accompanying notes. Actual results may differ materially from those estimates.
Foreign Currency Translation	Foreign Currency Translation HP predominantly uses the U.S. dollar as its functional currency. Assets and liabilities denominated in non-U.S. dollars are remeasured into U.S. dollars at current exchange rates for monetary assets and liabilities and at historical exchange rates for nonmonetary assets and liabilities. Net revenue, costs and expenses denominated in non-U.S. dollars are recorded in U.S. dollars at monthly average exchange rates prevailing during the period. HP includes gains or losses from foreign currency remeasurement in Interest and other, net in the Consolidated Statements of Earnings. Certain foreign subsidiaries designate the local currency as their functional currency, and HP records the translation of their assets and liabilities into U.S. dollars at the balance sheet dates as translation adjustments and includes them as a component of accumulated other comprehensive loss.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In February 2018, the FASB issued guidance, which eliminates the stranded tax effects in other comprehensive income resulting from the TCJA. Because the amendments only relate to the reclassification of the income tax effects of the TCJA, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from operations is not affected. HP early adopted this guidance in the third quarter of fiscal year 2019. The implementation of this guidance resulted in a $69 million reclassification from accumulated other comprehensive loss to accumulated deficit. In March 2017, the Financial Accounting Standards Board (“FASB”) issued guidance, which addresses the improvement of the presentation of net periodic pension and net periodic post-retirement benefit cost. The guidance requires entities to present the service cost component of net periodic benefit cost in the same income statement line item as other compensation costs arising from services rendered during the period. Additionally, the guidance requires that companies present the other components of the net periodic benefit cost separately from the line item that includes service cost and any other subtotal of income from operations. The amendments in this guidance are to be applied retrospectively for presentation in the Consolidated Statements of Earnings. A practical expedient allows companies to use the amount disclosed in its pension and other post-retirement plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. HP adopted this guidance in the first quarter of fiscal year 2019 and elected to use the practical expedient. The adoption of this guidance has no impact on net earnings. The reclassification resulted in an increase in total cost and expenses and a reduction in interest and other, net of $233 million for the twelve months ended October 31, 2018. In November 2016, the FASB issued guidance, which addresses the presentation of restricted cash in the statement of cash flows. The guidance requires entities to present the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. HP adopted this guidance in the first quarter of fiscal year 2019. The implementation of this guidance did not have any impact on its Consolidated Financial Statements. In October 2016, the FASB issued guidance, which amends the existing accounting for Intra-Entity Transfers of Assets Other Than Inventory. The guidance (Topic 740) requires an entity to recognize the income tax consequences of intra-entity transfers, other than inventory, when the transfer occurs. It also requires modified retrospective transition with a cumulative catch-up adjustment to opening retained earnings in the period of adoption. HP adopted this guidance in the first quarter of fiscal year 2019. The implementation of this guidance resulted in $353 million of net reduction to its prepaid tax asset adjusted through accumulated deficit. In the fourth quarter of fiscal year 2019, HP corrected this impact to $47 million by recording a deferred tax asset adjusted through accumulated deficit. In August 2016, the FASB issued guidance, which amends the existing accounting standards for the classification of certain cash receipts and cash payments on the statement of cash flows. HP adopted this guidance in the first quarter of fiscal year 2019. The implementation of this guidance did not have any impact on its Consolidated Financial Statements. In January 2016, the FASB issued guidance, which amends the existing accounting standards for the recognition and measurement of financial assets and financial liabilities. The guidance (Topic 825-10) primarily addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with other amendments related specifically to equity securities without readily determinable fair values applied prospectively. HP adopted this guidance in the first quarter of fiscal year 2019. The implementation of this guidance did not have a material impact on its Consolidated Financial Statements. In May 2014, the FASB issued guidance, which amends the existing accounting standards for revenue recognition. The amendments (Topic 606) are based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. HP adopted the new revenue standard in the first quarter of fiscal year 2019 using the modified retrospective method applied to contracts that were not completed as of November 1, 2018. HP recognized the net impact of adoption as an increase to accumulated deficit by $212 million , net of tax, on November 1, 2018. The primary changes that impact the Consolidated Financial Statements are as below: Variable consideration - HP estimates the transaction price for elements of consideration which are variable in nature. Certain distributor programs and incentive offerings which were recorded at the date the sales incentives were offered, are now recorded at the time of revenue recognition based on estimates. Costs to obtain a contract - The incremental costs to obtain a contract are primarily comprised of eligible sales commissions which were previously expensed as incurred. HP has capitalized such eligible sales commission costs for contracts with terms of more than one year and amortized those costs over the expected period of the benefit. The adoption has led to certain balance sheet reclassifications pertaining to return asset and liability and repurchase reserves which impacts accounts receivable, net, inventory, other current assets and other current liabilities balances. Recently Issued Accounting Pronouncements Not Yet Adopted In August 2017, the FASB issued guidance, which amends the existing accounting standards for derivatives and hedging. The amendment improves the financial reporting of hedging relationships to better represent the economic results of an entity’s risk management activities in its financial statements and made certain targeted improvements to simplify the application of the hedge accounting guidance in current U.S. GAAP. HP is required to adopt the guidance in the first quarter of fiscal year 2020. Earlier adoption is permitted. Based on the current assessment, HP expects that the implementation of this guidance will not have a material impact on its Consolidated Financial Statements. In June 2016, the FASB issued guidance, which requires credit losses on financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, not based on incurred losses. Further, credit losses on available-for-sale debt securities should be recorded through an allowance for credit losses limited to the amount by which fair value is below amortized cost. HP is required to adopt the guidance in the first quarter of fiscal year 2021. Earlier adoption is permitted. HP is currently evaluating the timing and the impact of this guidance on the Consolidated Financial Statements. In February 2016, the FASB issued guidance (“Topic 842”), which amends the existing accounting standards for leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification. Under the new guidance, a lessee will be required to recognize assets and liabilities for all leases with lease terms of more than twelve months. HP will adopt this guidance in the first quarter of fiscal year 2020 and will apply the modified retrospective transition option made available in July 2018 by the FASB, whereby comparative periods will not be retrospectively presented in the Consolidated Financial Statements. HP will also elect the package of practical expedients not to reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs and the lessee practical expedient to combine lease and non-lease components for certain asset classes. HP has established a cross-functional implementation team to assist in determining the scope of impact, identifying changes to its business processes, implementing a new system solution and evaluating changes to internal controls to support adoption of the new standard. HP currently expects the adoption of Topic 842 to result in an increase in right of use assets and a corresponding increase in lease liabilities on the Consolidated Balance Sheet of approximately $1.0 billion to $1.5 billion . Upon adoption, HP will also record revenue upfront on certain aspects of its MPS and DaaS offerings and will reflect the financing of these offerings as cash flows from financing activities on the Statement of Cash Flows. HP has substantially completed the process of quantifying the impacts that will result from applying the new guidance, and the assessment will be finalized during the first quarter of fiscal year 2020.
Revenue Recognition	Revenue Recognition General HP recognizes revenues at a point in time or over time depicting the transfer of promised goods or services to customers in an amount that reflects the consideration to which HP expects to be entitled in exchange for those goods or services. HP follows the five-step model for revenue recognition as summarized below: 1 . Identify the contract with a customer - A contract with customer exists when (i) it is approved and signed by all parties, (ii) each party’s rights and obligations can be identified, (iii) payment terms are defined, (iv) it has commercial substance and (v) the customer has the ability and intent to pay. HP evaluates customers’ ability to pay based on various factors like historical payment experience, financial metrics and customer credit scores. While the majority of our sales contracts contain standard terms and conditions, there are certain contracts with non-standard terms and conditions. 2. Identify the performance obligations in the contract - HP evaluates each performance obligation in an arrangement to determine whether it is distinct, such as hardware and/or service. A performance obligation constitutes distinct goods or services when the customer can benefit from such goods or services either on its own or together with other resources that are readily available to the customer and the performance obligation is distinct within the context of the contract. 3. Determine the transaction price - Transaction price is the amount of consideration to which HP expects to be entitled in exchange for transferring goods or services to the customer. If the transaction price includes a variable amount, HP estimates the amount it expects to be entitled to using either the expected value or most likely amount method. HP reduces the transaction price at the time of revenue recognition for customer and distributor programs and incentive offerings, rebates, promotions, other volume-based incentives and expected returns. HP uses estimates to determine the expected variable consideration for such programs based on factors like historical experience, expected consumer behavior and market conditions. HP has elected the practical expedient of not accounting for significant financing components if the period between revenue recognition and when the customer pays for the product or service is one year or less. 4. Allocate the transaction price to performance obligations in the contract - When a sales arrangement contains multiple performance obligations, such as hardware and/or services, HP allocates revenue to each performance obligation in proportion to their selling price. The selling price for each performance obligation is based on its SSP. HP establishes SSP using the price charged for a performance obligation when sold separately (“observable price”) and, in some instances, using the price established by management having the relevant authority. When observable price is not available, HP establishes SSP based on management judgment considering internal factors such as margin objectives, pricing practices and controls, customer segment pricing strategies and the product life-cycle. Consideration is also given to market conditions such as competitor pricing strategies and technology industry life cycles. 5. Recognize revenue when (or as) the performance obligation is satisfied - Revenue is recognized when, or as, a performance obligation is satisfied by transferring control of a promised good or service to a customer. HP generally invoices the customer upon delivery of the goods or services and the payments are due as per contract terms. For fixed price support or maintenance contracts that are in the nature of stand-ready obligations, payments are generally received in advance from customers and revenue is recognized on a straight-line basis over the duration of the contract. HP reports revenue net of any taxes collected from customers and remitted to government authorities, and the collected taxes are recorded as other current liabilities until remitted to the relevant government authority. HP includes costs related to shipping and handling in cost of revenue. HP records revenue on a gross basis when HP is a principal in the transaction and on a net basis when HP is acting as an agent between the customer and the vendor. HP considers several factors to determine whether it is acting as a principal or an agent, most notably whether HP is the primary obligor to the customer, has established its own pricing and has inventory and credit risks. Hardware HP transfers control of the products to the customer at the time the product is delivered to the customer and recognizes revenue accordingly, unless customer acceptance is uncertain or significant obligations to the customer remain unfulfilled. Services HP recognizes revenue from fixed-price support, maintenance and other service contracts over time depicting the pattern of service delivery and recognizes the costs associated with these contracts as incurred. Contract Assets and Liabilities Contract assets are rights to consideration in exchange for goods or services that HP has transferred to a customer when such right is conditional on something other than the passage of time. Such contract assets are not material to HP’s Consolidated Financial Statements. Contract liabilities are recorded as deferred revenues when amounts invoiced to customers are more than the revenues recognized or when payments are received in advance for fixed price support or maintenance contracts. The short-term and long-term deferred revenues are reported within the other current liabilities and other non-current liabilities respectively. Cost to obtain a contract and fulfillment cost Incremental direct costs of obtaining a contract primarily consist of sales commissions. HP has elected the practical expedient to expense as incurred the costs to obtain a contract with a benefit period equal to or less than one year. For contracts with a period of benefit greater than one year, HP capitalizes incremental costs of obtaining a contract with a customer and amortizes these costs over their expected period of benefit provided such costs are recoverable. Fulfillment costs consist of set-up and transition costs related to other service contracts. These costs generate or enhance resources of HP that will be used in satisfying the performance obligation in the future and are capitalized and amortized over the expected period of the benefit, provided such costs are recoverable. See Note 7, “Supplementary Financial Information” for details on net revenue by region, cost to obtain a contract and fulfillment cost, contract liabilities and value of remaining performance obligations. Transition disclosure In accordance with the modified retrospective method transition requirements, HP has presented the financial statement line items impacted and adjusted to compare to presentation under the prior GAAP for the Consolidated Balance Sheet as of October 31, 2019 and for Consolidated Statement of Earnings for fiscal year ended October 31, 2019.

Stock-Based Compensation	Stock-Based Compensation
Retirement and Post-Retirement Plans	Retirement and Post-Retirement Plans HP has various defined benefit, other contributory and non-contributory retirement and post-retirement plans. HP generally amortizes unrecognized actuarial gains and losses on a straight-line basis over the average remaining estimated service life of participants. In limited cases, HP amortizes actuarial gains and losses using the corridor approach. See Note 4, “Retirement and Post-Retirement Benefit Plans” for a full description of these plans and the accounting and funding policies.
Advertising	Advertising cost
Restructuring and Other Charges	Restructuring and Other Charges HP records charges associated with management-approved restructuring plans to reorganize one or more of HP’s business segments, to remove duplicative headcount and infrastructure associated with business acquisitions or to simplify business processes and accelerate innovation. Restructuring charges can include severance costs to reduce a specified number of employees, enhanced early retirement incentives, infrastructure charges to vacate facilities and consolidate operations, and contract cancellation costs. HP records restructuring charges based on estimated employee terminations, committed early retirements and site closure and consolidation plans. HP accrues for severance and other employee separation costs under these actions when it is probable that benefits will be paid and the amount is reasonably estimable. The rates used in determining severance accruals are based on existing plans, historical experiences and negotiated settlements. Other charges include non-recurring costs, including those as a result of the Separation or information technology rationalization efforts, and are distinct from ongoing operational costs.
Taxes on Earnings	Taxes on Earnings HP recognizes deferred tax assets and liabilities for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts using enacted tax rates in effect for the year the differences are expected to reverse. HP records a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized. HP records accruals for uncertain tax positions when HP believes that it is not more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. HP makes adjustments to these accruals when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. The provision for income taxes includes the effects of adjustments for uncertain tax positions, as well as any related interest and penalties.
Accounts Receivable	Accounts Receivable HP establishes an allowance for doubtful accounts for accounts receivable. HP records a specific reserve for individual accounts when HP becomes aware of specific customer circumstances, such as in the case of a bankruptcy filing or deterioration in the customer’s operating results or financial position. If there are additional changes in circumstances related to the specific customer, HP further adjusts estimates of the recoverability of receivables. HP maintains bad debt reserves for all other customers based on a variety of factors, including the use of third-party credit risk models that generate quantitative measures of default probabilities based on market factors, the financial condition of customers, the length of time receivables are past due, trends in the weighted-average risk rating for the portfolio, macroeconomic conditions, information derived from competitive benchmarking, significant one-time events and historical experience. The past due or delinquency status of a receivable is based on the contractual payment terms of the receivable.
Transfers and Servicing Trade Receivables Policy	HP has third-party short-term financing arrangements intended to facilitate the working capital requirements of certain customers. These financing arrangements, which in certain cases provide for partial recourse, result in the transfer of HP’s trade receivables to a third party. HP reflects amounts transferred to, but not yet collected from the third party in accounts receivable in the Consolidated Balance Sheets. For arrangements involving an element of recourse, the fair value of the recourse obligation is measured using market data from similar transactions and reported as a current liability in the Consolidated Balance Sheets.
Concentrations of Risk	Concentrations of Risk Financial instruments that potentially subject HP to significant concentrations of credit risk consist principally of cash and cash equivalents, investments, receivables from trade customers and contract manufacturers and derivatives. HP maintains cash and cash equivalents, investments, derivatives and certain other financial instruments with various financial institutions. These financial institutions are located in many different geographic regions, and HP’s policy is designed to limit exposure from any particular institution. As part of its risk management processes, HP performs periodic evaluations of the relative credit standing of these financial institutions. HP has not sustained material credit losses from instruments held at these financial institutions. HP utilizes derivative contracts to protect against the effects of foreign currency, interest rate and, on certain investment exposures. Such contracts involve the risk of non-performance by the counterparty, which could result in a material loss. The likelihood of which HP deems to be remote. HP sells a significant portion of its products through third-party distributors and resellers and, as a result, maintains individually significant receivable balances with these parties. If the financial condition or operations of these distributors’ and resellers’ aggregated business deteriorates substantially, HP’s operating results could be adversely affected. The ten largest distributor and reseller receivable balances, which were concentrated primarily in North America and Europe, collectively represented approximately 32% and 39% of gross accounts receivable as of October 31, 2019 and 2018, respectively. No single customer accounts for more than 10% of gross accounts receivable as of October 31, 2019 or 2018. Credit risk with respect to other accounts receivable is generally diversified due to HP’s large customer base and their dispersion across many different industries and geographic markets. HP performs ongoing credit evaluations of the financial condition of its third-party distributors, resellers and other customers and may require collateral, such as letters of credit and bank guarantees, in certain circumstances. HP utilizes outsourced manufacturers around the world to manufacture HP-designed products. HP may purchase product components from suppliers and sell those components to its outsourced manufacturers thereby creating receivable balances from the outsourced manufacturers. The three largest outsourced manufacturer receivable balances collectively represented 77% and 72% of HP’s supplier receivables of $1,165 million and $1,074 million as of October 31, 2019 and 2018, respectively. HP includes the supplier receivables in Other current assets in the Consolidated Balance Sheets on a gross basis. HP’s credit risk associated with these receivables is mitigated wholly or in part, by the amount HP owes to these outsourced manufacturers, as HP generally has the legal right to offset its payables to the outsourced manufacturers against these receivables. HP does not reflect the sale of these components in net revenue and does not recognize any profit on these component sales until the related products are sold by HP, at which time any profit is recognized as a reduction to cost of revenue. HP obtains a significant number of components from single source suppliers due to technology, availability, price, quality or other considerations. The loss of a single source supplier, the deterioration of HP’s relationship with a single source supplier, or any unilateral modification to the contractual terms under which HP is supplied components by a single source supplier could adversely affect HP’s net revenue and gross margins.
Inventory	Inventory HP values inventory at the lower of cost or market. Cost is computed using standard cost which approximates actual cost on a first-in, first-out basis. Adjustments, if required, to reduce the cost of inventory to market (net realizable value) are made, for estimated excess, obsolete or impaired balances.
Property, Plant and Equipment, net	Property, Plant and Equipment, Net HP reflects property, plant and equipment at cost less accumulated depreciation. HP capitalizes additions and improvements and expenses maintenance and repairs as incurred. Depreciation expense is recognized on a straight-line basis over the estimated useful lives of the assets. Estimated useful lives are five to 40 years for buildings and improvements and three to 15 years for machinery and equipment. HP depreciates leasehold improvements over the life of the lease or the asset, whichever is shorter. HP depreciates equipment held for lease over the initial term of the lease to the equipment’s estimated residual value. On retirement or disposition, the asset cost and related accumulated depreciation are removed from the Consolidated Balance Sheets with any gain or loss recognized in the Consolidated Statements of Earnings.
Internal Use Software and Cloud Computing Arrangements	Internal Use Software and Cloud Computing Arrangements HP capitalizes external costs and directly attributable internal costs to acquire or create internal use software which are incurred subsequent to the completion of the preliminary project stage. These costs relate to activities such as software design, configuration, coding, testing, and installation. Costs related to post-implementation activities such as training and maintenance are expensed as incurred. Once the software is substantially complete and ready for its intended use, capitalized development costs are amortized straight-line over the estimated useful life of the software, not to exceed five years . HP also enters into certain cloud-based software hosting arrangements that are accounted for as service contracts. For internal-use software obtained through a hosting arrangement that is in the nature of a service contract, HP incurs certain implementation costs such as integrating, configuring, and software customization, which are consistent with costs incurred during the application development stage for on-premise software. HP applies the same guidance to determine costs that are eligible for capitalization. For these arrangements, HP amortizes the capitalized development costs straight-line over the fixed, non-cancellable term of the associated hosting arrangement plus any reasonably certain renewal periods. HP also applies the same impairment model to both internal-use software and capitalized implementation costs in a software hosting arrangement that is in the nature of a service contract.
Business Combinations	Business Combinations HP includes the results of operations of the acquired business in HP’s consolidated results prospectively from the acquisition date. HP allocates the purchase consideration to the assets acquired, liabilities assumed, and non-controlling interests in the acquired entity generally based on their fair values at the acquisition date. The excess of the fair value of purchase consideration over the fair value of these assets acquired, liabilities assumed and non-controlling interests in the acquired entity is recorded as goodwill. The primary items that generate goodwill include the value of the synergies between the acquired company and HP and the value of the acquired assembled workforce, neither of which qualify for recognition as an intangible asset. Acquisition-related charges are recognized separately from the business combination and are expensed as incurred. These charges primarily include, direct third-party professional and legal fees, and integration-related costs.
Goodwill	Goodwill HP reviews goodwill for impairment annually during its fourth quarter and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. HP can elect to perform a qualitative assessment to test a reporting unit’s goodwill for impairment or HP can directly perform the quantitative impairment test. Based on the qualitative assessment, if HP determines that the fair value of a reporting unit is more likely than not (i.e., a likelihood of more than 50 percent) to be less than its carrying amount, a quantitative impairment test will be performed. In the quantitative impairment test, HP compares the fair value of each reporting unit to its carrying amount with the fair values derived most significantly from the income approach, and to a lesser extent, the market approach. Under the income approach, HP estimates the fair value of a reporting unit based on the present value of estimated future cash flows. HP bases cash flow projections on management’s estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions. HP bases the discount rate on the weighted-average cost of capital adjusted for the relevant risk associated with business-specific characteristics and the uncertainty related to the reporting unit’s ability to execute on the projected cash flows. Under the market approach, HP estimates fair value based on market multiples of revenue and earnings derived from comparable publicly-traded companies with similar operating and investment characteristics as the reporting unit. HP weights the fair value derived from the market approach depending on the level of comparability of these publicly-traded companies to the reporting unit. When market comparables are not meaningful or not available, HP estimates the fair value of a reporting unit using only the income approach. In order to assess the reasonableness of the estimated fair value of HP’s reporting units, HP compares the aggregate reporting unit fair value to HP’s market capitalization on an overall basis and calculates an implied control premium (the excess of the sum of the reporting units’ fair value over HP’s market capitalization on an overall basis). HP evaluates the control premium by comparing it to observable control premiums from recent comparable transactions. If the implied control premium is determined to not be reasonable in light of these recent transactions, HP re-evaluates its reporting unit fair values, which may result in an adjustment to the discount rate and/or other assumptions. This re-evaluation could result in a change to the estimated fair value for certain or all reporting units. If the fair value of a reporting unit exceeds the carrying amount of the net assets assigned to that reporting unit, goodwill is not impaired. If the fair value of the reporting unit is less than its carrying amount, goodwill is impaired and the excess of the reporting unit’s carrying value over the fair value is recognized as an impairment loss.
Debt and Marketable Equity Securities Investments	Debt and Marketable Equity Securities Investments HP determines the appropriate classification of its investments at the time of purchase and re-evaluates the classifications at each balance sheet date. Debt and marketable equity securities are generally considered available-for-sale. All highly liquid investments with maturities of three months or less at the date of purchase are classified as cash equivalents. Marketable debt securities with maturities of twelve months or less are classified as short-term investments and marketable debt securities with maturities greater than twelve months are classified based on their availability for use in current operations. Marketable equity securities, including mutual funds, are classified as either short-term or long-term based on the nature of each security and its availability for use in current operations. Debt and marketable equity securities are reported at fair value with unrealized gains and losses, net of applicable taxes, in Accumulated Other Comprehensive Loss, Consolidated Statement of Earnings and the Consolidated Balance Sheets. Realized gains and losses on available-for-sale securities are calculated based on the specific identification method and included in interest and other, net in the Consolidated Statements of Earnings. HP monitors its investment portfolio for potential impairment on a quarterly basis. When the carrying amount of an investment in debt securities exceeds its fair value and the decline in value is determined to be other-than-temporary (i.e., when HP does not intend to sell the debt securities and it is not more likely than not that HP will be required to sell the debt securities prior to anticipated recovery of its amortized cost basis), HP records an impairment charge to Interest and other, net in the amount of the credit loss and the remaining amount, if any, is recorded in Accumulated other comprehensive loss in the Consolidated Balance Sheets.
Derivatives	Derivatives HP uses derivative instruments, primarily forwards, swaps, and at times, options, to hedge certain foreign currency, interest rate, and return on certain investment exposures. HP also may use other derivative instruments not designated as hedges, such as forwards used to hedge foreign currency balance sheet exposures. HP does not use derivative instruments for speculative purposes. See Note 10, “Financial Instruments” for a full description of HP’s derivative instrument activities and related accounting policies.
Loss Contingencies	Loss Contingencies HP is involved in various lawsuits, claims, investigations and proceedings that arise in the ordinary course of business. HP records a liability for contingencies when it believes it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. See Note 14, “Litigation and Contingencies” for a full description of HP’s loss contingencies and related accounting policies.
Segment Information	The accounting policies HP uses to derive segment results are substantially the same as those used by HP in preparing these financial statements. HP derives the results of the business segments directly from its internal management reporting system.
Fair Value	Valuation Techniques Cash Equivalents and Investments: HP holds time deposits, money market funds, mutual funds, other debt securities primarily consisting of corporate and foreign government notes and bonds, and common stock and equivalents. HP values cash equivalents and equity investments using quoted market prices, alternative pricing sources, including net asset value, or models utilizing market observable inputs. The fair value of debt investments was based on quoted market prices or model-driven valuations using inputs primarily derived from or corroborated by observable market data, and, in certain instances, valuation models that utilize assumptions which cannot be corroborated with observable market data. Derivative Instruments: From time to time, HP uses forward contracts, interest rate and total return swaps and, in the past, option contracts to hedge certain foreign currency interest rate and return on certain investment exposures. HP uses industry standard valuation models to measure fair value. Where applicable, these models project future cash flows and discount the future amounts to present value using market-based observable inputs, including interest rate curves, HP and counterparty credit risk, foreign exchange rates, and forward and spot prices for currencies and interest rates. See Note 10, “Financial Instruments” for a further discussion of HP’s use of derivative instruments. Other Fair Value Disclosures Short- and Long-Term Debt: HP estimates the fair value of its debt primarily using an expected present value technique, which is based on observable market inputs using interest rates currently available to companies of similar credit standing for similar terms and remaining maturities, and considering its own credit risk. The portion of HP’s debt that is hedged is reflected in the Consolidated Balance Sheets as an amount equal to the debt’s carrying amount and a fair value adjustment representing changes in the fair value of the hedged debt obligations arising from movements in benchmark interest rates. The fair value of HP’s short- and long-term debt was $5.4 billion at October 31, 2019 compared to its carrying amount of $5.1 billion at that date. The fair value of HP’s short- and long-term debt was $6.0 billion as compared to its carrying value of $6.0 billion at October 31, 2018. If measured at fair value in the Consolidated Balance Sheets, short- and long-term debt would be classified in Level 2 of the fair value hierarchy. Other Financial Instruments: For the balance of HP’s financial instruments, primarily accounts receivable, accounts payable and financial liabilities included in other current liabilities on the Consolidated Balance Sheets, the carrying amounts approximate fair value due to their short maturities. If measured at fair value in the Consolidated Balance Sheets, these other financial instruments would be classified in Level 2 or Level 3 of the fair value hierarchy. Non-Marketable Equity Investments and Non-Financial Assets: HP’s non-marketable equity investments are measured at cost less impairment, adjusted for observable price changes. HP’s non-financial assets, such as intangible assets, goodwill and property, plant and equipment, are recorded at fair value in the period an impairment charge is recognized. If measured at fair value in the Consolidated Balance Sheets these would generally be classified within Level 3 of the fair value hierarchy. Fair Value Hierarchy HP uses valuation techniques that are based upon observable and unobservable inputs. Observable inputs are developed using market data such as publicly available information and reflect the assumptions market participants would use, while unobservable inputs are developed using the best information available about the assumptions market participants would use. Assets and liabilities are classified in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement: Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2—Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market-corroborated inputs. Level 3—Unobservable inputs for the asset or liability. The fair value hierarchy gives the highest priority to observable inputs and lowest priority to unobservable inputs.
Earnings Per Share	HP calculates basic net EPS using net earnings and the weighted-average number of shares outstanding during the reporting period. Diluted net EPS includes any dilutive effect of restricted stock units, stock options, performance-based awards and shares purchased under the 2011 employee stock purchase plan.
Guarantees, Indemnifications and Warranties	Guarantees In the ordinary course of business, HP may issue performance guarantees to certain of its clients, customers and other parties pursuant to which HP has guaranteed the performance obligations of third parties. Some of those guarantees may be backed by standby letters of credit or surety bonds. In general, HP would be obligated to perform over the term of the guarantee in the event a specified triggering event occurs as defined by the guarantee. HP believes the likelihood of having to perform under a material guarantee is remote. Cross-Indemnifications with Hewlett Packard Enterprise Under the separation and distribution agreement, HP agreed to indemnify Hewlett Packard Enterprise, each of its subsidiaries and each of their respective directors, officers and employees from and against all liabilities relating to, arising out of or resulting from, among other matters, the liabilities allocated to HP as part of the Separation. Hewlett Packard Enterprise similarly agreed to indemnify HP, each of its subsidiaries and each of their respective directors, officers and employees from and against all liabilities relating to, arising out of or resulting from, among other matters, the liabilities allocated to Hewlett Packard Enterprise as part of the Separation. HP expects Hewlett Packard Enterprise to fully perform under the terms of the separation and distribution agreement. For information on cross-indemnifications with Hewlett Packard Enterprise for litigation matters, see Note 14, “Litigation and Contingencies”. In connection with the Separation, HP entered into the TMA with Hewlett Packard Enterprise, effective on November 1, 2015. The TMA provided that HP and Hewlett Packard Enterprise will share certain pre-Separation income tax liabilities. The TMA was terminated during the fourth quarter of fiscal year 2019. Indemnifications In the ordinary course of business, HP enters into contractual arrangements under which HP may agree to indemnify a third party to such arrangement from any losses incurred relating to the services they perform on behalf of HP or for losses arising from certain events as defined within the particular contract, which may include, for example, litigation or claims relating to past performance. HP also provides indemnifications to certain vendors and customers against claims of intellectual property infringement made by third parties arising from the vendors’ and customers’ use of HP’s software products and services and certain other matters. Some indemnifications may not be subject to maximum loss clauses. Historically, payments made related to these indemnifications have been immaterial. HP records tax indemnification receivables from various third parties for certain tax liabilities that HP is jointly and severally liable for, but for which it is indemnified by those same third parties under existing legal agreements. HP records a tax indemnification payable to various third parties under these agreements when management believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. The actual amount that the parties pay or may be obligated to pay could vary depending on the outcome of certain unresolved tax matters, which may not be resolved for several years. The net payable and net receivable as of October 31, 2019 and October 31, 2018 were $57 million and $1.0 billion , respectively. During fiscal year 2019, $1.0 billion of indemnification receivables was reduced primarily due to resolution of various tax matters amounting to $0.8 billion . Warranties HP accrues the estimated cost of product warranties at the time it recognizes revenue. HP engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers; however, contractual warranty terms, repair costs, product call rates, average cost per call, current period product shipments and ongoing product failure rates, as well as specific product class failures outside of HP’s baseline experience, affect the estimated warranty obligation.

(2) The fair value of corporate, government and asset-backed debt securities is based on observable inputs of comparable market transactions. Also included in this category is debt issued by national, state and local governments and agencies. (3) Department of Labor 103-12 IE (Investment Entity) designation is for plan assets held by two or more unrelated employee benefit plans which includes limited partnerships and venture capital partnerships. Certain common collective trusts and interests in 103-12 entities are valued using NAV as a practical expedient. (4) Includes publicly traded funds of investment companies that are registered with the SEC, funds that are not publicly traded and a non-U.S. fund-of-fund arrangement. The non-U.S. fund-of-fund arrangement is a custom portfolio valued at NAV consisting primarily of fixed income and common contractual funds. (5) Includes cash and cash equivalents such as short-term marketable securities. Cash and cash equivalents include money market funds, which are valued based on NAV. Other assets were classified in the fair value hierarchy based on the lowest level input (e.g., quoted prices and observable inputs) that is significant to the fair value measure in its entirety. (6) Includes primarily reverse repurchase agreements, unsettled transactions, and derivative instruments. (7) Alternative Investments primarily include private equities and hedge funds. The valuation of alternative investments, such as limited partnerships and joint ventures, may require significant management judgment. For alternative investments, valuation is based on NAV as reported by the asset manager or investment company and adjusted for cash flows, if necessary. In making such an assessment, a variety of factors are reviewed by management, including but not limited to the timeliness of NAV as reported by the asset manager and changes in general economic and market conditions subsequent to the last NAV reported by the asset manager. • Private equities include limited partnerships such as equity, buyout, venture capital, real estate and other similar funds that invest in the United States and internationally where foreign currencies are hedged. • Hedge funds include limited partnerships that invest both long and short primarily in common stocks and credit, relative value, event-driven equity, distressed debt and macro strategies. Management of the hedge funds has the ability to shift investments from value to growth strategies, from small to large capitalization stocks and bonds, and from a net long position to a net short position. (8) The Common Contractual Fund is an investment arrangement in which institutional investors pool their assets. Units may be acquired in different sub-funds focused on equities, fixed income, alternative investments and emerging markets. Each sub-fund is invested in accordance with the fund’s investment objective and units are issued in relation to each sub-fund. While the sub-funds are not publicly traded, the custodian strikes a NAV either once or twice a month, depending on the sub-fund. These assets are valued using NAV as a practical expedient.

Weighted-Average Fair Value and Assumptions Used to Measure Fair Value of Restricted Stock Units	HP uses the closing stock price on the grant date to estimate the fair value of service-based restricted stock units. HP estimates the fair value of restricted stock units subject to performance-adjusted vesting conditions using a combination of the closing stock price on the grant date and the Monte Carlo simulation model. The weighted-average fair value and the assumptions used to measure the fair value of restricted stock units subject to performance-adjusted vesting conditions in the Monte Carlo simulation model were as follows: For the fiscal years ended October 31 2019 2018 2017 Weighted-average fair value (1) $ 27 $ 24 $ 20 Expected volatility (2) 26.5 % 29.5 % 30.5 % Risk-free interest rate (3) 2.7 % 1.9 % 1.4 % Expected performance period in years (4) 2.9 2.9 2.9 (1) The weighted-average fair value was based on performance-adjusted restricted stock units granted during the period. (2) The expected volatility was estimated using the historical volatility derived from HP’s common stock.

Weighted-Average Fair Value and Assumptions Used to Measure Fair Value of Stock Options	HP utilizes the Black-Scholes-Merton option pricing formula to estimate the fair value of stock options subject to service-based vesting conditions. HP estimates the fair value of stock options subject to performance-contingent vesting conditions using a combination of a Monte Carlo simulation model and a lattice model as these awards contain market conditions. The weighted-average fair value and the assumptions used to measure fair value were as follows: For the fiscal years ended October 31 2019 2018 2017 Weighted-average fair value (1) $ 3 $ 5 $ 4 Expected volatility (2) 29.8 % 29.4 % 28.0 % Risk-free interest rate (3) 1.7 % 2.5 % 1.9 % Expected dividend yield (4) 3.7 % 2.6 % 2.8 % Expected term in years (5) 6.0 5.0 5.5 (1) The weighted-average fair value was based on stock options granted during the period. (2) For all awards granted in fiscal year 2019 and 2018, expected volatility was estimated based on a blended volatility ( 50% historical volatility and 50% implied volatility from traded options on HP's common stock). For the awards granted in fiscal year 2017, expected volatility was estimated using the leverage-adjusted average of the term-matching volatilities of peer companies due to the lack of volume of forward traded options, which precluded the use of implied volatility. (3) The risk-free interest rate was estimated based on the yield on U.S. Treasury zero-coupon issues. (4) The expected dividend yield represents a constant dividend yield applied for the duration of the expected term of the award. (5)
