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
HP has reclassified certain prior-year amounts to conform to the current-year presentation.
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. As of October 31, 2021, the extent to which the COVID-19 pandemic will impact our business going forward depends on numerous dynamic factors which we cannot reliably predict. As a result, many of our estimates and assumptions required increased judgment and may carry a higher degree of variability and volatility. As the events continue to evolve with respect to the pandemic, our estimates may materially change in future periods.
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 non-monetary 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
On November 1, 2015, Hewlett-Packard Company completed the separation of Hewlett Packard Enterprise Company (“Hewlett Packard Enterprise”), Hewlett-Packard Company’s former enterprise technology infrastructure, software, services and financing businesses (the “Separation”). In connection with the Separation, HP and Hewlett Packard Enterprise entered into a separation and distribution agreement and various other agreements which remain enforceable and provide a framework for the continuing relationships between the parties. For more information on the impacts of these agreements, see Note 14, “Litigation and Contingencies”.
Oracle litigation proceeds
On October 12, 2021, Oracle paid approximately $4.65 billion, to satisfy the judgement with interest, related to the litigation in connection with Oracle’s discontinuation of software support for former Hewlett-Packard Company’s Itanium-based line of mission-critical servers. The net proceeds from the judgement are being shared equally between HP and Hewlett Packard Enterprise pursuant to the terms of the separation and distribution agreement. For the fiscal year 2021, HP has recorded a gain of $2.3 billion in Interest and other, net and corresponding tax impact of $0.5 billion in Provision for taxes on the Consolidated Statements of Earnings as HP believes that the likelihood of the reduction or reversal of the judgement is remote. For more information, see Note 14, “Litigation and Contingencies”.
Recently Adopted Accounting Pronouncements
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. Furthermore, 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 adopted the new credit loss standard as of November 1, 2020 using a modified retrospective approach. The cumulative effect upon adoption was not material to the Consolidated Financial Statements.
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 the 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 Standalone Selling Price (“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. HP records revenue from the sale of equipment under sales-type leases as revenue at the commencement of the lease.
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.
Leases
At the inception of a contract, HP assesses whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of a distinct identified asset, (2) whether HP obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether HP has the right to direct the use of the asset.
All significant lease arrangements are recognized at lease commencement. Leases with a lease term of 12 months or less at inception are not recorded on the Consolidated Balance Sheets and are expensed on a straight-line basis over the lease term in the Consolidated Statement of Earnings. HP determines the lease term by assuming the exercise of renewal options that are reasonably certain. As most of the leases do not provide an implicit interest rate, HP uses the unsecured borrowing rate and risk-adjusts that rate to approximate a collateralized rate at the commencement date to determine the present value of future payments that are reasonably certain.
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 $829 million, $530 million and $652 million in fiscal years 2021, 2020 and 2019, 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 information technology rationalization efforts and proxy contest activities, 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 records allowance for credit losses for the current expected credit losses inherent in the asset over its expected life. The allowance for credit losses is maintained based on the relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount.
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 assesses collectability by pooling receivables where similar risk characteristics exist.
HP maintains an allowance for credit losses 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, financial condition of customers, 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 43% and 47% of gross accounts receivable as of October 31, 2021 and 2020, respectively. No single customer accounts for more than 10% of gross accounts receivable as of October 31, 2021 or 2020. 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 85% and 89% of HP’s supplier receivables of $1.4 billion and $1.2 billion as of October 31, 2021 and 2020, 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, cash flows 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.
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 after considering judgments related to future demand and market conditions, along with the impact of COVID-19.
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, generally 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
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
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
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 or long-term based on the nature of each security and its availability for use in current operations.
Available-for-sale debt securities are reported at fair value with unrealized gains and losses, net of applicable taxes, in Accumulated other comprehensive loss. Unrealized gains and losses on equity securities, credit losses and impairments on available-for-sale debt securities are recorded in Consolidated Statements of Earnings. Realized gains and losses on available-for-sale securities are calculated at the individual security level and included in Interest and other, net in the Consolidated Statements of Earnings.
HP monitors its investment portfolio for potential impairment and credit losses on a quarterly basis. If HP intends to sell a debt security or it is more likely than not that HP will be required to sell the security before recovery, then a decline in fair value below cost is recorded as an impairment charge in Interest and other, net and a new cost basis in the investment is established.
In other cases, if the carrying amount of an investment in debt securities exceeds its fair value and the decline in value is determined to be due to credit related reasons, HP records a credit loss allowance, limited by the amount that fair value is less than the amortized cost basis. HP recognizes the corresponding charge in Interest and other, net and the remaining unrealized loss, if any, in Accumulated other comprehensive loss in the Consolidated Balance Sheets. Factors that HP considers while determining the credit loss allowance includes, but is not limited to, severity and the reason for the decline in value, interest rate changes and counterparty long-term ratings.
Derivatives
HP uses derivative instruments, primarily forward contracts, interest rate swaps, total return swaps, treasury rate locks, forward starting swaps and, at times, option contracts 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
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 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, small- and medium-sized businesses (“SMBs”) and large enterprises, including customers in the government, health and education sectors. HP goes to market through its extensive channel network and direct sales.
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 the 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 personal computers (“PCs”), workstations, thin clients, commercial mobility devices, retail point-of-sale (“POS”) systems, displays and peripherals, 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:

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 $0.8 billion primarily in labor costs related to workforce reductions and the remaining costs will relate to non-labor actions and other charges.
Other charges
Other charges include non-recurring costs, including those as a result of information technology rationalization efforts and proxy contest activities, and are distinct from ongoing operational costs. These costs primarily relate to third-party legal, professional services and other non-recurring costs. HP incurred $22 million, $105 million and $28 million of other charges in fiscal year 2021, 2020 and 2019, respectively.

Retirement and Post-Retirement Benefit Plans

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, 2021 and 2020, the fair value of plan assets of the DPSP was $482 million and $463 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.
In August 2021, HP entered into an agreement with The Prudential Insurance Company of America (“Prudential”) to purchase an irrevocable group annuity contract and transfer approximately $5.2 billion of the Pension Plan obligations. Under the agreement, Prudential assumed responsibility for pension benefits and annuity administration for approximately 41,000 retirees and beneficiaries, with no changes to the amount or timing of monthly retirement benefit payments. This transaction closed in the fourth quarter of fiscal year 2021 and was funded by the assets of the Pension Plan. HP recorded a settlement gain of approximately $39 million in Interest and other, net on the Consolidated Statements of Earnings, with no cash flow impact.
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 $112 million in fiscal year 2021, $108 million in fiscal year 2020 and $107 million in fiscal year 2019.
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 the first 4% of eligible compensation contributed by employees, and the employer match is vested after three years of employee service. Generally, an employee must be employed by HP Inc. on the last day of the calendar year to receive a match.

The cumulative net actuarial losses for our defined pension plans and retiree welfare plans decreased year over year. The decrease in losses is primarily due to the higher than expected returns on assets, increases in discount rates, partially offset by
increases in the cost of living assumptions and the recognition of gains as a result of the U.S. settlement. This has also resulted in improvement in the funded status of HP’s defined benefit and post-retirement benefit plans.

The weighted-average assumptions used to calculate the projected benefit obligations for the fiscal years ended October 31, 2021 and 2020 were as follows:

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)These investments include alternative investments, which primarily consist of 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.
These investments also include Common Collective Trusts and 103-12 Investment Entities as defined in note (3) above and Investment Funds as defined in note (4) above.

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 (pension and post-retirement) 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. Due to the strong funded status for the U.S. Pension Plan, consistent with our policy, steps have been taken to de-risk the portfolio by reallocation of assets to liability hedging fixed-income investments. HP also invests a portion of the U.S. defined 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 where appropriate, can offer some assistance in the selection of investment managers, 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 were at least 50 years old with 20 or more years of service at HP. Employees accepted into the EER program left HP on dates ranging from December 31, 2019 to September 30, 2020. The EER benefit was a cash lump sum payment which was 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 were offered the opportunity to continue health care coverage at the active employee contribution rates for up to 36 months following retirement. In addition, HP provided up to $12,000 in employer credits under the Retirement Medical Savings Account (“RMSA”) program. In relation to the continued health care
coverage and employer credits under the RMSA program, HP recognized special termination benefit costs of $44 million as restructuring and other charges for the twelve months ended October 31, 2020.
Lump Sum Program
    HP offered a lump sum program during the third quarter of fiscal year 2020. Certain terminated vested participants in the HP Inc. Pension Plan (“Pension Plan”) could elect to take a one-time voluntary lump sum payment equal to the present value of future benefits. Approximately 12,000 participants elected the lump sum option. Payments of $2.2 billion were made from plan assets to the participants in the fourth quarter of fiscal year 2020. A non-cash settlement expense of $214 million arising from the accelerated recognition of previously deferred actuarial losses was recorded in the fourth quarter of fiscal year 2020.
Future Contributions and Funding Policy
In fiscal year 2022, HP expects to contribute approximately $44 million to its non-U.S. pension plans, $36 million to cover benefit payments to U.S. non-qualified plan participants and $4 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, 2021, HP estimates that the future benefits payments for the retirement and post-retirement plans are as follows:

The benefit realized for the tax deduction from option exercises in fiscal years 2021, 2020 and 2019 was $3 million, $2 million and $3 million, respectively.
Stock-Based Incentive Compensation Plans 
HP’s stock-based incentive compensation plan includes equity plan adopted in 2004, as amended and restated (“principal equity plan”). Stock-based awards granted under the equity plan includes 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 principal equity plan is 593.1 million.
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. HP also grants performance-adjusted restricted stock units which 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 plan are generally non-qualified stock options, but the principal equity plan permits 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. HP grants performance-contingent stock options that vest only on the satisfaction of both service and market conditions prior to the expiration of the awards.
RSU and stock option grants provide for accelerated vesting in certain circumstances as defined in the plans and related grant agreements, including termination in connection with a change in control.
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 a Monte Carlo simulation model. 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:

The total grant date fair value of restricted stock units vested in fiscal years 2021, 2020 and 2019 was $278 million, $297 million and $273 million, respectively. As of October 31, 2021, total unrecognized pre-tax stock-based compensation expense related to non-vested restricted stock units was $297 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:

(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.

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 2021, 2020 and 2019. 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 2021, 2020 and 2019 was $18 million, $12 million and $20 million, respectively. The total grant date fair value of options vested in fiscal years 2021, 2020 and 2019 was $3 million, $3 million and $9 million, respectively.
As of October 31, 2021, total unrecognized pre-tax stock-based compensation expense related to stock options was $10 million, which is expected to be recognized over a weighted-average vesting period of 1.4 years.
Employee Stock Purchase Plan
HP sponsors the 2021 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 2021 ESPP, employees purchase stock under the 2021 ESPP at a price equal to 95% of HP’s closing stock price on the purchase date. No stock-based compensation expense was recorded in connection with those purchases because the criteria of a non-compensatory plan were met. The aggregate number of shares of HP’s stock authorized for issuance under the 2021 ESPP was 50 million. The 2021 ESPP came into effect on May 1, 2021 upon expiry of the 2011 ESPP. The 2021 ESPP terms are similar to the previous ESPP.
Shares Reserved

In fiscal year 2021, HP recorded $9 million of net income tax charges related to discrete items in the provision for taxes. This amount included income tax charges of $533 million related to the Oracle litigation proceeds, $15 million of uncertain tax
position charges, and $9 million of other net tax charges. These charges were partially offset by income tax benefits of $393 million related to changes in valuation allowances, $89 million of tax effects related to internal reorganization, $50 million related to restructuring charges, and $16 million related to the filing of tax returns in various jurisdictions. In fiscal year 2021, excess tax benefits associated with stock options, restricted stock units and performance-adjusted restricted stock units were immaterial.
In fiscal year 2020, HP recorded $244 million of net income tax benefits related to discrete items in the provision for taxes. This amount included tax benefits related to audit settlements of $124 million in various jurisdictions and $82 million related to restructuring benefits. Additionally, HP recorded benefits of $20 million related to proxy contest costs and $17 million of other net tax benefits. In fiscal year 2020, excess tax benefits associated with stock options, restricted stock units and performance-adjusted restricted stock units were immaterial.
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 included 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.
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 2029. The gross income tax benefits attributable to these actions and investments were estimated to be $385 million ($0.32 diluted net EPS) in fiscal year 2021, $344 million ($0.24 diluted net EPS) in fiscal year 2020 and $386 million ($0.25 diluted net EPS) in fiscal year 2019.

Balance at end of year$820 $820 $929 
 
As of October 31, 2021, the amount of gross unrecognized tax benefits was $820 million, of which up to $660 million would affect HP’s effective tax rate if realized. As of October 31, 2020, the amount of unrecognized tax benefits was $820 million of which up to $657 million would affect HP’s effective tax rate if realized. The amount of unrecognized tax benefit changed by a net immaterial amount. 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, 2021, 2020 and 2019, HP had accrued $70 million, $34 million and $56 million, respectively, for interest and penalties.
HP engages in continuous discussions and negotiations with taxing authorities regarding tax matters in various jurisdictions. HP expects complete resolution of certain tax years with various tax authorities within the next 12 months. HP believes it is reasonably possible that its existing gross unrecognized tax benefits may be reduced by up to $72 million within the next 12 months, affecting HP’s effective tax rate if realized.
HP is subject to income tax in the United States and approximately 60 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 2018 and 2019 income tax returns.
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 related to ongoing audits as of October 31, 2021.
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, 2021 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.

Gross deferred tax assets as of October 31, 2021, 2020, and 2019 were reduced by valuation allowances of $7.7 billion,$8.0 billion and $7.9 billion, respectively. In fiscal year 2021, the deferred tax asset valuation allowance decreased by $227 million primarily due to the expected utilization of 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. In fiscal year 2020, the deferred tax asset valuation allowance increased by $46 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 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. This increase was partially offset by the impact of tax rate changes in foreign jurisdictions and state valuation allowance releases.

HP has third-party arrangements, consisting of revolving short-term financing, which provide liquidity to certain partners to facilitate their working capital requirements. 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 on the Consolidated Balance Sheets. The recourse obligations as of October 31, 2021 and 2020 were not material. The costs associated with the sales of trade receivables for fiscal year 2021, 2020 and 2019 were not material.

Value of Remaining Performance Obligations
    As of October 31, 2021, the estimated value of transaction price allocated to remaining performance obligations was $3.7 billion. HP expects to recognize approximately $1.7 billion of the unearned amount in next 12 months and $2.0 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 and Fulfillment Cost
As of October 31, 2021, deferred contract fulfillment and acquisition costs balances were $65 million and $36 million, respectively, included in Other Current Assets and Other Non-Current Assets in the Consolidated Balance Sheets. During the fiscal year ended October 31, 2021, the Company amortized $79 million of these costs.
As of October 31, 2020, deferred contract fulfillment and acquisition costs balances were $65 million and $34 million, respectively, included in Other Current Assets and Other Non-Current Assets in the Consolidated Balance Sheets. During the fiscal year ended October 31, 2020, the Company amortized $98 million of these costs.
Contract Liabilities
As of October 31, 2021 and 2020, HP’s contract liabilities balances were $2.3 billion and $2.2 billion, respectively, included in Other Current Liabilities and Other Non-Current Liabilities in the Consolidated Balance Sheets.
The increase in the contract liabilities balance for the fiscal year 2021 was primarily driven by sales of fixed-price support and maintenance services, partially offset by $1.1 billion of revenue recognized that were included in the opening contract liabilities balance as of October 31, 2020.
As of October 31, 2020 and 2019, HP’s contract liabilities balances were $2.2 billion and $2.1 billion, respectively, included in Other Current Liabilities and Other Non-Current Liabilities in the Consolidated Balance Sheets.
The increase in the contract liabilities balance for the fiscal year 2020 was primarily driven by sales of fixed-price support and maintenance services, partially offset by $1.1 billion of revenue recognized that were included in the opening contract liabilities balance as of October 31, 2019.

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:

 (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 traded 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 is 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: 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 $8.0 billion as compared to its carrying amount of $7.5 billion at October 31, 2021. The fair value of HP’s short- and long-term debt was $6.7 billion as compared to its carrying value of $6.2 billion at October 31, 2020. 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 as 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.

(1)HP classifies its marketable debt securities as available-for-sale investments within Other current assets on the Consolidated Balance Sheets, including those with maturity dates beyond one year, based on their highly liquid nature and availability for use in current operations.
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, 2021 and 2020, 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 $31 million in fiscal year 2021, $40 million in fiscal year 2020, and $80 million in fiscal year 2019. The estimated fair value of the available-for-sale investments may not be representative of values that will be realized in the future.
Contractual maturities of investments in available-for-sale debt securities were as follows:

Non-marketable equity securities in privately held companies are included in Other non-current assets in the Consolidated Balance Sheets. These amounted to $59 million and $44 million as of October 31, 2021 and 2020, respectively.
HP determines credit losses on cash equivalents and available-for-sale debt securities at the individual security level. All instruments are considered investment grade. No credit-related or noncredit-related impairment losses were recorded in the fiscal year 2021.
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, treasury rate locks, forward starting 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 $64 million and $90 million as of October 31, 2021 and 2020, 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, 2021 and 2020.
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 benchmark interest rates on HP’s future interest payments.
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.
During the fiscal year 2021, HP entered into interest rate swaps with a notional amount of $375 million that were designated as fair value hedges, to convert a portion of its fixed-rate debt to floating. HP terminated interest rate swaps with a notional amount of $500 million that were de-designated as fair value hedges, including $250 million notional amount related to certain fixed-rate debt securities that were extinguished, resulting in an immaterial loss.
Cash Flow Hedges
HP uses forward contracts, treasury rate locks, forward starting swaps and, at times, option contracts designated as cash flow hedges to protect against the foreign currency exchange and interest rate risks inherent in its forecasted net revenue, cost of revenue, operating expenses and debt issuance. 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 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 changes in the fair value of the derivative instrument in the same financial statement line item as changes in the fair value of the hedged item.
During the fiscal year 2021, HP entered into a series of forward starting swap agreements with notional amounts totaling $2.25 billion to hedge the exposure to variability in future cash flows resulting from changes in interest rate related to anticipated issuance of long-term debt. These agreements were designated as cash flow hedges. In June 2021, a series of these forward starting swaps totaling $750 million notional amount were settled upon the issuance of the senior notes resulting in an immaterial loss recognized in Accumulated other comprehensive loss. The loss will be reclassified to Interest and other, net over the life of the related debt.
Other Derivatives
Other derivatives not designated as hedging instruments consist primarily of forward contracts used to hedge foreign currency-denominated balance sheet exposures. HP also 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, forward contracts and forward starting swaps 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.
During the fiscal 2021 and 2020, no portion of the hedging instruments’ gain or loss was excluded from the assessment of effectiveness for fair value and cash flow hedges.

As of October 31, 2021, HP expects to reclassify an estimated Accumulated other comprehensive gain of approximately $10 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 other comprehensive loss based on the change of market rate, and therefore could have different impact on earnings.

(1)HP may redeem some or all of the fixed-rate U.S. Dollar Global Notes at any time in accordance with the terms thereof. The U.S. Dollar Global Notes are senior unsecured debt.
In June 2021, HP completed its offering of $2.0 billion aggregate principal amount of senior unsecured notes, consisting of $1.0 billion of 1.450% notes due June 2026 (the “2026 Notes”), and $1.0 billion of 2.650% notes due June 2031 (the “2031 Notes”). HP incurred issuance costs of $17 million. HP will pay interest semi-annually on the notes on June 17 and December 17, beginning December 17, 2021. In June 2021, HP terminated a series of forward starting swap agreements with notional amounts totaling $750 million that were executed to mitigate the treasury rate volatility associated with this debt issuance. The net proceeds from the 2026 Notes were used for general corporate purposes, including redemption of existing notes maturing in 2021, as described below. HP intends to allocate an amount equal to the net proceeds of the 2031 Notes to finance or refinance, in whole or in part, environmentally and socially responsible eligible projects in the following eight areas: renewable energy; green buildings; energy efficiency; clean transportation; pollution prevention and control; eco-efficient and/or circular economy products, production technologies and processes; environmentally sustainable management of living natural resources and land use; and socioeconomic advancement and empowerment.
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 benchmark interest rates. 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, 2021, aggregate future maturities of debt at face value (excluding unamortized debt issuance cost of $51 million, discounts on debt issuance of $14 million, and fair value adjustment related to hedged debt of $16 million), including other borrowings were as follows:

Extinguishment of Debt
In July 2021, HP redeemed the remaining aggregate principal amounts of $0.4 billion in outstanding U.S. Dollar 4.375% Global Notes due September 15, 2021 and $0.6 billion in outstanding U.S. Dollar 4.650% Global Notes due December 9, 2021. This extinguishment of debt resulted in a net loss of $16 million, which was recorded as Interest and other, net on the Consolidated Statements of Earnings.
As part of the above transactions, HP terminated and settled interest rate swaps with a notional amount of $250 million that were de-designated as fair value hedges.
Commercial Paper
As of October 31, 2021, 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 Facilities
As of October 31, 2021, HP maintained a $5.0 billion sustainability-linked senior unsecured committed revolving credit facility (the “New Revolving Facility”), which HP entered into on May 26, 2021. Commitments under the New Revolving Facility will be available until May 26, 2026. As of October 31, 2020, HP had maintained a $4.0 billion senior unsecured committed revolving credit facility and a $1.0 billion 364-day revolving credit facility to support the issuance of commercial paper or for general corporate purposes. Commitments under the $4.0 billion and $1.0 billion revolving credit facilities were terminated concurrently with the execution of the New Revolving Facility.
Commitment fees, interest rates and other terms of borrowing under the New Revolving Facility vary based on HP’s external credit ratings and certain sustainability metrics. Funds borrowed under the New Revolving Facility may be used for general corporate purposes.
As of October 31, 2021, HP was in compliance with the covenants in the New Revolving Facility.
Available Borrowing Resources
As of October 31, 2021, HP had available borrowing resources of $579 million from uncommitted lines of credit in addition to the New Revolving Facility.

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, 2021, 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, challenging the imposition or the modification of levies regimes upon IT equipment (such as PCs or printers) or the restrictions to exonerate the application of private copying levies on devices purchased by business users. The levies are generally based upon the number of products sold and the per-product amounts of the levies, which vary. Some European countries are expected to implement legislation to introduce or extend existing levy schemes to digital devices. HP, other companies and various industry associations have opposed the extension of levies to the digital environment and certain requirements for business sales exemptions, and have advocated alternative models of compensation to rights holders.
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. In the first phase of the bifurcated trial, 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. In the second phase, 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. The court entered judgment for HP for this amount with interest accruing until the judgment is paid. Oracle appealed the trial court’s judgment and HP filed a cross-appeal challenging the trial court’s denial of prejudgment interest. The Court of Appeals affirmed both the trial court’s judgment and its denial of prejudgment interest to HP. Oracle filed a petition with the California Supreme Court for review, which was denied on September 29, 2021. On October 12, 2021, Oracle paid approximately $4.65 billion to satisfy the judgment with interest. During the fourth quarter of fiscal 2021, HP recorded approximately $2.3 billion as a gain (Interest and other, net) in relation to the damages awarded, representing HP’s interest in the amount recovered, which is being shared equally between HP and Hewlett Packard Enterprise, less $47.4 million reimbursed to Hewlett Packard Enterprise for certain costs incurred in the prosecution of the action prior to the Separation. Oracle has until December 28, 2021 to file a petition for certiorari asking the United States Supreme Court for review. Review by the United States Supreme Court is discretionary, and HP believes the likelihood the award of damages will be reduced or reversed is remote.
Forsyth, et al. v. 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 (“HPE”) alleging the defendants violated federal and state law by terminating older workers and replacing them with younger workers. In their most recent complaint, plaintiffs seek to represent (1) a putative nationwide federal Age Discrimination in Employment Act (ADEA) collective comprised of all former HP Inc. employees 40 years of age and older who had their employment terminated under a WFR plan in or after 2014 or 2015, depending on state law; and (2) a putative Rule 23 class under California law comprised of all former HP Inc. employees 40 years of age and older who had their employment terminated in California under a WFR plan in or after 2012. Excluded from the putative collective and class are employees who (a) signed a Waiver and General Release Agreement at termination, or (b) signed an Agreement to Arbitrate Claims. Similar
claims are pending against HPE. Because the court granted plaintiffs’ motion for preliminary certification of the putative nationwide ADEA collectives, a third-party administrator has notified eligible former employees of their right to opt into the ADEA collective. Former employees must opt in by February 15, 2022. Plaintiffs seek monetary damages, punitive damages, and other relief.
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 and interest. Prior to the issuance of the 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 or interrupt business by HP India.
On April 11, 2012, the Bangalore Commissioner of Customs issued an order on the products-related 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 notice. The differential duty demand is subject to interest. On April 20, 2012, the Commissioner issued an order on the parts-related 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 notice so as to avoid certain penalties.
HP India filed appeals of the Commissioner’s orders before the Customs, Excise and Service Tax Appellate Tribunal (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. On February 7, 2014, the Customs Tribunal granted HP India’s application for extension of the stay of deposit until disposal of the appeals. On October 27, 2014, the Customs Tribunal commenced hearings on the cross-appeals of the Commissioner’s orders and rejected HP India’s request to remand the matter to the Commissioner on procedural grounds. The Customs Tribunal cancelled hearings to reconvene in 2015, 2016, and January 2019. On January 20, 2021, the Customs Tribunal held a virtual hearing during which the judge allowed HP’s application for a physical hearing on the merits as soon as practicable, which will be scheduled when physical hearings resume at court. 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.
Philips Patent Litigation. In September 2020, Koninklijke Philips N.V. and Philips North America LLC (collectively, “Philips”) filed a complaint against HP for patent infringement in federal court for the District of Delaware and filed a companion complaint with the U.S. International Trade Commission (“ITC”) pursuant to Section 337 of the Tariff Act against HP and 8 other sets of respondents. Both complaints allege that certain digital video-capable devices and components thereof infringe four of Philips patents. In October 2020, the ITC instituted an investigation, and Philips later withdrew two of the four patents. On October 21, 2021, the ITC rendered an initial determination that there is no violation of Section 337. The ITC is expected to render a final decision by February 22, 2022. In the ITC proceeding, Philips seeks an order enjoining respondents from importing, or selling after importation, the accused products. In the district court case, Philips seeks unspecified damages and an injunction against HP, and the case has been stayed pending resolution of the ITC proceeding.
Caltech Patent Litigation. On November 11, 2020, the California Institute of Technology (“Caltech”) filed a complaint against HP for patent infringement in the federal court for the Western District of Texas. On March 19, 2021, Caltech filed an amendment to this same complaint. The complaint as amended alleges infringement of five of Caltech’s patents, U.S. Patent Nos. 7,116,710; 7,421,032; 7,716,552; 7,916,781; and 8,284,833. The accused products are HP commercial and consumer PCs as well as wireless printers that comply with the IEEE 802.11n, 802.11ac, and/or 802.11ax standards. Caltech seeks unspecified damages and other relief. The court has stayed the case pending the decision by the U.S. Court of Appeals for the Federal Circuit in The California Inst. of Tech. v. Broadcom Ltd et al., Case No. 2020-2222.
In re HP Inc. Securities Litigation (Electrical Workers Pension Fund, Local 103, I.B.E.W. v. HP Inc., et al.). On February 19, 2020, Electrical Workers Pension Fund, Local 103, I.B.E.W. filed a putative class action complaint against HP, Dion Weisler, Catherine Lesjak, and Steven Fieler in U.S. District Court in the Northern District of California. The court appointed the State of Rhode Island, Office of the General Treasurer, on behalf of the Employees’ Retirement System of Rhode Island and Iron Workers Local 580 Joint Funds as Lead Plaintiffs. Lead Plaintiffs filed an amended complaint, which
additionally named as defendants Enrique Lores and Christoph Schell. HP and the named officers filed a motion to dismiss the complaint for failure to state a claim upon which relief can be granted. The court granted HP’s motion to dismiss and granted plaintiffs leave to amend the complaint. Plaintiffs’ second amended complaint, which no longer names Christoph Schell as a defendant, alleges, among other things, that from February 23, 2017 to October 3, 2019, HP and the named officers violated Sections 10(b) and 20(a) of the Exchange Act by making false or misleading statements about HP’s printing supplies business. It further alleges that Dion Weisler and Enrique Lores violated Sections 10(b) and 20A of the Exchange Act by allegedly selling shares of HP common stock during this period while in possession of material, non-public adverse information about HP’s printing supplies business. Plaintiffs seek compensatory damages and other relief. HP and the named officers filed a motion to dismiss the second amended complaint for failure to state a claim upon which relief can be granted. On September 15, 2021, the court granted HP’s motion. Plaintiffs are appealing the decision.
York County on behalf of the County of York Retirement Fund v. HP Inc., et al., and related proceedings. On November 5, 2020, York County, on behalf of the County of York Retirement Fund, filed a putative class action complaint against HP, Dion Weisler, and Catherine Lesjak in federal court in the Northern District of California. The court appointed Maryland Electrical Industry Pension Fund as Lead Plaintiff. Lead Plaintiff filed a consolidated complaint, which additionally names as defendants Enrique Lores and Richard Bailey. The complaint alleges, among other things, that from November 5, 2015 to June 21, 2016, HP and the named current and former officers violated Sections 10(b) and 20(a) of the Exchange Act by concealing material information and making false statements about HP’s printing supplies business. Plaintiff seeks compensatory damages and other relief. HP and the named officers filed a motion to dismiss the complaint for failure to state a claim upon which relief can be granted. That motion is fully briefed. On May 17, 2021, stockholder Scott Franklin filed a derivative complaint against certain current and former officers and directors in federal court in the District of Delaware. Plaintiff purports to bring the action on behalf of HP, which he has named as a nominal defendant, and it makes substantially the same factual allegations as in the York County securities complaint, bringing claims for breach of fiduciary duty and violations of securities laws. The derivative plaintiff seeks compensatory damages, governance reforms, and other relief. By court order following stipulations by the parties, the case was transferred to the Northern District of California, and the case was stayed pending a ruling on the motion to dismiss in York County.
Legal Proceedings re Authentication of Supplies. Civil litigation or government investigations involving supplies authentication protocols used in certain HP printers are pending, have concluded, or may be filed or opened in multiple geographies, including but not limited to the United States, Italy, Israel, and the Netherlands. The supplies authentication protocols are often referred to as Dynamic Security. The core allegations in these proceedings claim misleading or inadequate consumer notifications and permissions pertaining to the use of Dynamic Security, the impact of firmware updates, or the potential inability of cartridges with clone chips or circuitry to work in HP printers with Dynamic Security.
123Inkt Foundation litigation (Netherlands). On November 23, 2016, a foundation known as Stichting 123Inkt-Huismerk Klanten (the “Foundation”) filed a complaint in district court in Amsterdam against HP Nederland B.V. and HP Inc. arising out of the use of Dynamic Security in certain OfficeJet printers. Digital Revolution B.V. (trading as 123Inkt) established the Foundation to pursue the interests of approximately 960 of its customers who transferred their claims to it. The complaint alleges that HP’s use of Dynamic Security was unlawful, asserts a variety of claims, and seeks injunctive relief to prohibit use of Dynamic Security, damages, and attorneys’ fees. In December 2019, the Amsterdam Court of Appeal rejected the Foundation’s argument that Dynamic Security is unlawful but ruled that error messages displayed on HP printers in September 2016 without providing prior warning regarding Dynamic Security were misleading. Both parties appealed to the Supreme Court of the Netherlands. In July 2021, the Attorney General issued a non-binding opinion concluding that both parties’ appeals should be rejected. The Supreme Court has scheduled its final decision to be delivered on January 7, 2022.
Gensin v. HP Inc. (Israel). HP is named in a consolidated, consumer class action pending in the District Court in Jerusalem relating to HP’s use of Dynamic Security in certain OfficeJet printers, which was initially filed on October 25,2017. Plaintiff asserts consumer protection, tort and other statutory claims primarily on the basis that no information on Dynamic Security was available in Hebrew, and plaintiff seeks class relief, injunctive relief, damages, and attorneys’ fees. HP has reached an agreement to settle this case, which has been submitted to the Court for approval. The Court has scheduled a hearing for January 13, 2022 to address any issues that may arise with the settlement.
Parziale v. HP Inc. (United States). In August 2019, HP was named in this purported nationwide consumer class action in federal court in the Northern District of California arising out of the use of Dynamic Security in certain OfficeJet printers. Plaintiff’s Second Amended Complaint alleged claims under Florida Consumer Protection statutes, the federal Computer Fraud and Abuse Act, and for trespass to chattels. Plaintiff sought class relief, injunctive relief, damages, including punitive damages, and attorneys’ fees. On September 29, 2020, the court granted HP’s motion to dismiss, dismissing the case in
full with prejudice. The plaintiff appealed, and the parties subsequently reached a settlement. On August 2, 2021, the plaintiff dismissed the appeal with prejudice.
Consumer Protection Investigation (Italy). In December 2020, the Italian Competition Authority (Autorità Garante della Concorrenza e del Mercato) (“AGCM”) notified HP of its decision that HP engaged in unfair commercial practices with respect to its disclosures to consumers about Dynamic Security and alleged use of certain warranty and data collection practices regarding the use of third-party cartridges in HP printers. The AGCM decision (i) ordered HP to end the allegedly unfair commercial practices; (ii) fined HP €5 million for each alleged unfair practice (total €10 million); (iii) required HP to file a compliance report within 60 days; (iv) ordered HP to publicly publish a corrective statement within 120 days; and (v) ordered HP to amend the packaging of its printers within 120 days. On December 21, 2020, HP paid the imposed fines. On February 5, 2021, HP filed an appeal. On April 6, 2021, HP filed its compliance report, which it subsequently supplemented, and, on June 23, 2021 the AGCM accepted the compliance plan as sufficient. HP’s appeal is pending in front of the Regional Administrative Court of Lazio.
Digital Revolution B.V. v. HP Nederland B.V., et al. (Netherlands). On March 30, 2020, Digital Revolution B.V. (trading as 123Inkt) served a complaint filed in Amsterdam District Court. The complaint generally alleges that HP’s use of Dynamic Security in certain HP printers constituted a violation of competition law and unfair and misleading commercial practices and advertising. The complaint asserts a variety of claims and seeks injunctive relief, including prohibition of Dynamic Security and disclosure of cartridge authentication protocols, damages, and attorneys’ fees. On September 9, 2020, HP filed its defense and a counterclaim for unfair commercial practices and misleading and unlawful comparative advertising. The Court held an oral hearing on September 13, 2021. The Court’s decision has not yet issued and is subject to appeal.
Mobile Emergency Housing Corp., et al. v. HP, Inc. (United States). In December 2020, HP was named in a putative nationwide consumer class action pending in federal court in California arising out of the use of Dynamic Security firmware updates in certain LaserJet printers. The complaint alleges a variety of claims, including state consumer protection and unfair business claims and state and federal computer access and data collection claims. Plaintiffs seek compensatory damages, restitution, injunctive relief against alleged unfair business practices, and other relief. The case is in its early stages and discovery has commenced.
Autonomy-Related Legal Matters
Investigations. As a result of the findings of an internal investigation, HP provided information to government authorities, including the U.S. Department of Justice (“DOJ”) related to accounting improprieties, disclosure failures and misrepresentations at Autonomy that occurred before and in connection with HP’s 2011 acquisition of Autonomy. In November 2016, a federal grand jury indicted Sushovan Hussain, former CFO of Autonomy on charges of 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 Autonomy’s true financial performance and condition. On April 30, 2018, a jury found Mr. Hussain guilty of all charges against him, and that judgment was affirmed on appeal in August 2020. In November 2018, a federal grand jury indicted Michael Lynch, former CEO of Autonomy, and Stephen Chamberlain, former VP of Finance of Autonomy. The indictment charged Dr. Lynch and Mr. Chamberlain 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. Trial began on March 25, 2019 and was completed in January 2020. The parties are awaiting a ruling from the Court.
Environmental
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.

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
The separation and distribution agreement provides for cross-indemnities between HP and Hewlett Packard Enterprise for liabilities allocated to the respective party pursuant to the terms of such agreement. For information on cross-indemnifications with Hewlett Packard Enterprise for litigation matters, see Note 14, “Litigation and Contingencies”.
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 third parties pay or may be obligated to pay HP could vary depending on the outcome of certain unresolved tax matters, which may not be resolved for several years.
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.

Leases

Leases [Abstract]  
Leases Leases
HP determines, at lease inception, whether or not an arrangement contains a lease. A significant portion of the operating lease portfolio includes real estate leases. Additionally, HP has identified embedded operating leases within certain outsourced supply chain contracts. Leasing arrangements typically range in terms from 1 to 12 years with varying renewal and termination options. Substantially all of HP’s leases are considered operating leases. Finance leases, short-term leases and sub-lease income were not material as of October 31, 2021 and 2020 or for the fiscal years ended October 31, 2021 and 2020, respectively.
Lease terms include options to extend or terminate the lease when it is reasonably certain that HP will exercise such options. HP generally considers the economic life of the ROU assets to be comparable to the useful life of similar owned assets. HP’s leases generally do not provide a residual guarantee.
Operating leases are included in Other non-current assets, Other current liabilities and Other non-current liabilities. Finance leases are included in Property, plant and equipment, net, Notes payable and short-term borrowings and Long-term debt in the Consolidated Balance Sheets.
As most of the leases do not provide an implicit interest rate, HP uses the incremental borrowing rate based on the information available at the commencement date of a lease in determining the present value of lease payments. The incremental borrowing rate is determined based on the rate of interest that HP would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. HP uses the unsecured borrowing rate and risk-adjusts that rate to approximate a collateralized rate.
HP has elected the practical expedient to combine lease and non-lease components as a single lease element for its real estate leases and certain outsourced supply chain contracts in calculating the ROU assets and lease liabilities. Where HP chooses not to combine the lease and non-lease components, HP allocates contract consideration to the lease and non-lease components based on relative standalone prices.
HP reviews the impairment of the ROU assets consistent with the approach applied for other long-lived assets.
The components of lease expense are as follows:
For the fiscal years ended October 31
 20212020
 In millions
Operating lease cost$235 $236 
Variable cost101 108 
Total lease expense$336 $344 
All lease expenses, including variable lease costs, are primarily included in Cost of revenue and Selling, general and administrative expenses in the Consolidated Statements of Earnings based on the use of the facilities.
Variable lease expense relates primarily to leased real estate utilized for office space and outsourced warehousing. These costs primarily include adjustments for inflation, payments dependent on a rate or index or usage of asset and common area maintenance charges. These costs are not included in the lease liability and are recognized in the period in which they are incurred.
The following table presents supplemental information relating to the cash flows arising from lease transactions. Cash payments made from variable lease costs and short-term leases are not included in the measurement of operating lease liabilities, and, as such, are excluded from the amounts below:

Business Combination and Asset Acquisition [Abstract]  
Acquisitions Acquisitions
Acquisitions in fiscal 2021
In fiscal 2021, HP completed four acquisitions. The estimated fair value of the assets acquired and liabilities assumed at the acquisition date for all four acquisitions, as set forth in the table below, reflects various preliminary fair value estimates and analyses, including preliminary work performed by third-party valuation specialists, which are subject to change within the measurement period as valuations are finalized. The fair values of certain tangible assets and liabilities acquired, the valuation of intangible assets acquired, certain legal matters, income and non income-based taxes, and residual goodwill are not yet finalized and subject to change. HP expects to continue to obtain information to assist in the calculation of the fair value of the net assets acquired at the acquisition date during the measurement period.
Pro forma results of operations for these acquisitions have not been presented because they are not material to HP’s consolidated results of operations, either individually or in the aggregate. Goodwill, which represents the excess of the purchase price over the net tangible and intangible assets acquired, is not deductible for tax purposes.

The following table presents the aggregate estimated fair values of the assets acquired and liabilities assumed, including those items that are still preliminary allocations, for all of HP's acquisitions in fiscal 2021:

Goodwill$400 
Amortizable intangible assets385 
Net assets acquired120 
Total fair value of consideration$905 
Acquisition of HyperX, the gaming division of Kingston Technology Company
HP’s largest acquisition in fiscal 2021 was its acquisition of HyperX, the gaming division of Kingston Technology Company which was completed in June 2021 with a total fair value purchase consideration of $412 million. The acquisition supports HP’s strategy to drive growth in gaming and peripherals within the Personal Systems segment. In connection with this acquisition, HP recorded approximately $112 million of goodwill and $197 million of amortizable purchased intangible assets.

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
HP has reclassified certain prior-year amounts to conform to the current-year presentation.
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. As of October 31, 2021, the extent to which the COVID-19 pandemic will impact our business going forward depends on numerous dynamic factors which we cannot reliably predict. As a result, many of our estimates and assumptions required increased judgment and may carry a higher degree of variability and volatility. As the events continue to evolve with respect to the pandemic, our estimates may materially change in future periods.
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 non-monetary 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
Recently Adopted Accounting Pronouncements
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. Furthermore, 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 adopted the new credit loss standard as of November 1, 2020 using a modified retrospective approach. The cumulative effect upon adoption was not material to the Consolidated Financial Statements.
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 the 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 Standalone Selling Price (“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. HP records revenue from the sale of equipment under sales-type leases as revenue at the commencement of the lease.
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.
Leases
Leases
At the inception of a contract, HP assesses whether the contract is, or contains, a lease. The assessment is based on (1) whether the contract involves the use of a distinct identified asset, (2) whether HP obtains the right to substantially all the economic benefit from the use of the asset throughout the period, and (3) whether HP has the right to direct the use of the asset.
All significant lease arrangements are recognized at lease commencement. Leases with a lease term of 12 months or less at inception are not recorded on the Consolidated Balance Sheets and are expensed on a straight-line basis over the lease term in the Consolidated Statement of Earnings. HP determines the lease term by assuming the exercise of renewal options that are reasonably certain. As most of the leases do not provide an implicit interest rate, HP uses the unsecured borrowing rate and risk-adjusts that rate to approximate a collateralized rate at the commencement date to determine the present value of future payments that are reasonably certain.
Stock-Based Compensation Stock-Based CompensationHP 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
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 Advertising costCosts to produce advertising are expensed as incurred during production. Costs to communicate advertising are expensed when the advertising is first run.
Restructuring and Other Charges Restructuring and Other ChargesHP 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 information technology rationalization efforts and proxy contest activities, 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 records allowance for credit losses for the current expected credit losses inherent in the asset over its expected life. The allowance for credit losses is maintained based on the relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount.
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 assesses collectability by pooling receivables where similar risk characteristics exist.
HP maintains an allowance for credit losses 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, financial condition of customers, 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
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 43% and 47% of gross accounts receivable as of October 31, 2021 and 2020, respectively. No single customer accounts for more than 10% of gross accounts receivable as of October 31, 2021 or 2020. 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 85% and 89% of HP’s supplier receivables of $1.4 billion and $1.2 billion as of October 31, 2021 and 2020, 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, cash flows 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 after considering judgments related to future demand and market conditions, along with the impact of COVID-19.
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, generally 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 or long-term based on the nature of each security and its availability for use in current operations.
Available-for-sale debt securities are reported at fair value with unrealized gains and losses, net of applicable taxes, in Accumulated other comprehensive loss. Unrealized gains and losses on equity securities, credit losses and impairments on available-for-sale debt securities are recorded in Consolidated Statements of Earnings. Realized gains and losses on available-for-sale securities are calculated at the individual security level and included in Interest and other, net in the Consolidated Statements of Earnings.
HP monitors its investment portfolio for potential impairment and credit losses on a quarterly basis. If HP intends to sell a debt security or it is more likely than not that HP will be required to sell the security before recovery, then a decline in fair value below cost is recorded as an impairment charge in Interest and other, net and a new cost basis in the investment is established.
In other cases, if the carrying amount of an investment in debt securities exceeds its fair value and the decline in value is determined to be due to credit related reasons, HP records a credit loss allowance, limited by the amount that fair value is less than the amortized cost basis. HP recognizes the corresponding charge in Interest and other, net and the remaining unrealized loss, if any, in Accumulated other comprehensive loss in the Consolidated Balance Sheets. Factors that HP considers while determining the credit loss allowance includes, but is not limited to, severity and the reason for the decline in value, interest rate changes and counterparty long-term ratings.
Derivatives
Derivatives
HP uses derivative instruments, primarily forward contracts, interest rate swaps, total return swaps, treasury rate locks, forward starting swaps and, at times, option contracts 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.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
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.
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 is 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: 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 $8.0 billion as compared to its carrying amount of $7.5 billion at October 31, 2021. The fair value of HP’s short- and long-term debt was $6.7 billion as compared to its carrying value of $6.2 billion at October 31, 2020. 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 as 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.
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 2021 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
The separation and distribution agreement provides for cross-indemnities between HP and Hewlett Packard Enterprise for liabilities allocated to the respective party pursuant to the terms of such agreement. For information on cross-indemnifications with Hewlett Packard Enterprise for litigation matters, see Note 14, “Litigation and Contingencies”.
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 third parties pay or may be obligated to pay HP could vary depending on the outcome of certain unresolved tax matters, which may not be resolved for several years.
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.

Investments at Fair Value$10,463 $1,064 $481 
(1)Investments in publicly traded equity securities are valued using the closing price on the measurement date as reported on the stock exchange on which the individual securities are traded.
(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.
(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)These investments include alternative investments, which primarily consist of 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.
These investments also include Common Collective Trusts and 103-12 Investment Entities as defined in note (3) above and Investment Funds as defined in note (4) above.

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 a Monte Carlo simulation model. 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

Expected performance period in years(3)
2.92.92.9
(1)The expected volatility was estimated using the historical volatility derived from HP’s common stock.
(2)The risk-free interest rate was estimated based on the yield on U.S. Treasury zero-coupon issues.
(3)The expected performance period was estimated based on the length of the remaining performance period from the grant date.

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.
