Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Organization and Description of the Business Navistar International Corporation ("NIC"), incorporated under the laws of the State of Delaware in 1993, is a holding company whose principal operating entities are Navistar, Inc. ("NI") and Navistar Financial Corporation ("NFC"). References herein to the "Company," "we," "our," or "us" refer collectively to NIC and its consolidated subsidiaries, including certain variable interest entities ("VIEs") of which we are the primary beneficiary. We operate in four principal industry segments: Truck, Parts, Global Operations (collectively called "Manufacturing operations"), and Financial Services, which consists of NFC and our foreign finance operations (collectively called "Financial Services operations"). These segments are discussed in Note 16, Segment Reporting . Our fiscal year ends on October 31. As such, all references to 2020 , 2019 , and 2018 contained within this Annual Report on Form 10-K relate to the fiscal year, unless otherwise indicated. Basis of Presentation and Consolidation The accompanying audited consolidated financial statements include the assets, liabilities, and results of operations of our Manufacturing operations and our Financial Services operations, including VIEs of which we are the primary beneficiary. The effects of transactions among consolidated entities have been eliminated to arrive at the consolidated amounts. Variable Interest Entities We have an interest in several VIEs, primarily joint ventures, established to manufacture or distribute products and enhance our operational capabilities. We have determined for certain of our VIEs that we are the primary beneficiary because we have the power to direct the activities of the VIE that most significantly impact its economic performance and we have the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. Accordingly, we include in our consolidated financial statements the assets and liabilities and results of operations of those entities, even though we may not own a majority voting interest. The liabilities recognized as a result of consolidating these VIEs do not represent additional claims on our general assets; rather they represent claims against the specific assets of these VIEs. Assets of these entities are not readily available to satisfy claims against our general assets. We are the primary beneficiary of our Blue Diamond Parts, LLC ("BDP") joint venture with Ford Motor Company ("Ford"). As a result, our Consolidated Balance Sheets include assets of $37 million and $32 million , and liabilities of $3 million and $4 million , as of October 31, 2020 and 2019 , respectively. Assets include $4 million and $2 million of cash and cash equivalents as of October 31, 2020 and 2019 , respectively, which are not readily available to satisfy claims against our general assets. The creditors of BDP do not have recourse to our general credit. In October 2019, Ford notified the Company of its intention to dissolve the BDP joint venture effective October 2021. Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include secured assets of $661 million and $927 million as of October 31, 2020 and 2019 , respectively, and liabilities of $610 million and $838 million as of October 31, 2020 and 2019 , respectively, all of which are involved in securitizations that are treated as asset-backed debt. In addition, our Consolidated Balance Sheets include secured assets of $397 million and $537 million as of October 31, 2020 and 2019 , respectively, and corresponding liabilities of $288 million and $279 million , at the respective dates, which are related to other secured transactions that do not qualify for sale accounting treatment, and therefore, are treated as borrowings secured by operating and finance leases. Investors that hold securitization debt have a priority claim on the cash flows generated by their respective securitized assets to the extent that the related VIEs are required to make principal and interest payments. Investors in securitizations of these entities have either no recourse, or limited recourse, to our general credit. We also have an interest in other VIEs, which we do not consolidate because we are not the primary beneficiary. Our financial support and maximum loss exposure relating to these non-consolidated VIEs are not material to our financial condition, results of operations, or cash flows. We use the equity method to account for our investments in entities that we do not control under the voting interest or variable interest models, but where we can exercise significant influence over operating and financial policies. Equity in income of non-consolidated affiliates includes our share of the net income of these entities. Related Party Transactions We have a series of commercial relationships and agreements with TRATON SE and certain of its subsidiaries and affiliates ("TRATON Group"), who holds 16.8% of our common stock, for royalties related to use of certain engine technology, contract manufacturing operations performed by us, the sale of engines, the sale and purchase of parts, and a procurement joint venture. We also have development agreements with TRATON Group involving certain engine and transmission projects. This development work is being expensed as incurred. During the third quarter of 2020, we informed MAN, a subsidiary of the TRATON Group, of the cancellation of a certain engine program. The parties disagree about the effects of the cancellation under the terms of the applicable agreement and are having commercial discussions related to the consequences of the program cancellation. The ultimate resolution may result in additional expenses which could be material. We are unable to estimate the amount of these expenses at this time. Revenue recognized for the years ended October 31, 2020 , 2019 and 2018 was approximately $122 million , $157 million and $146 million , respectively. Net expenses incurred for the years ended October 31, 2020 , 2019 and 2018 were $48 million , $37 million and $27 million , respectively, included primarily in Engineering and product development costs in our Consolidated Statements of Operations. Our receivable from TRATON Group was $18 million and $13 million as of October 31, 2020 and 2019 , respectively. Our payable to TRATON Group was $90 million and $55 million as of October 31, 2020 and 2019 , respectively. We have an exclusive long-term agreement to supply military and commercial parts and chassis to our former defense business, ND Holdings, LLC (“Navistar Defense”), in which we retain a 30% ownership interest. We also entered into an intellectual property agreement and a transition services agreement. For the years ended October 31, 2020 and 2019 , revenue recognized was approximately $48 million and $57 million , respectively. As of October 31, 2020 and 2019 , our receivables from Navistar Defense were $8 million and $29 million , respectively. Cash and Cash Equivalents All highly liquid financial instruments with original maturities of 90 days or less, consisting primarily of U.S. Treasury bills, federal agency securities, and commercial paper, are classified as cash equivalents. Restricted cash is related to our securitization facilities, senior and subordinated floating rate asset-backed notes, wholesale trust agreements, indentured trust agreements, letters of credit, Environmental Protection Agency ("EPA") requirements, and workers compensation requirements. The restricted cash and cash equivalents for our securitized facilities are restricted to pay interest expense, principal, or other amounts associated with our securitization agreements. Derivative Instruments We utilize derivative instruments to manage certain exposure to changes in foreign currency exchange rates, interest rates, and commodity prices. The fair values of all derivative instruments are recognized as assets or liabilities at the balance sheet date. Changes in the fair value of these derivative instruments are recognized in our operating results or included in AOCL , depending on whether the derivative instrument is a fair value or cash flow hedge and whether it qualifies for hedge accounting treatment. We elected to apply the normal purchase and normal sale exclusion to certain commodity contracts that are entered into to be used in production within a reasonable time during the normal course of business. For the years ended October 31, 2020 , 2019 , and 2018 , we elected not to use hedge accounting and all changes in the fair value of our derivatives, except for those qualifying under the normal purchases and normal sales exception, were recognized in our operating results. Gains and losses on derivative instruments are recognized in Costs of products sold , Interest expense , or Other expense, net depending on the underlying exposure. The exchange of cash associated with derivative transactions is classified in the Consolidated Statements of Cash Flows in the same category as the cash flows from the items subject to the economic hedging relationships. Trade and Finance Receivables Trade Receivables Trade accounts receivable and trade notes receivable primarily arise from sales of goods to independently owned and operated dealers, original equipment manufacturers ("OEMs"), and commercial customers in the normal course of business. Finance Receivables Finance receivables consist of the following: • Retail notes —Retail notes primarily consist of fixed rate loans to commercial customers to facilitate their purchase of new and used trucks, and related equipment. • Finance leases —Finance leases consist of direct financing leases to commercial customers for acquisition of new and used trucks, and related equipment. • Wholesale notes —Wholesale notes primarily consist of variable rate loans to our dealers for the purchase of new and used trucks, and related equipment. • Retail accounts —Retail accounts consist of short-term accounts receivable that finance the sale of products to commercial customers. • Wholesale accounts —Wholesale accounts consist of short-term accounts receivable primarily related to the sales of items other than trucks, and related equipment (e.g. service parts) to dealers. Finance receivables are classified as held-to-maturity and are recorded at gross value less unearned income and are reported net of allowances for doubtful accounts. Unearned revenue is amortized to revenue over the life of the receivable using the effective interest method. Our Financial Services operations purchase the majority of the wholesale notes receivable and accounts receivable arising from our Manufacturing operations. The Financial Services operations retain as collateral a security interest in the equipment associated with retail notes, wholesale notes, and finance leases. Sales of Trade and Finance Receivables We sell finance receivables using a process commonly known as securitization, whereby asset-backed securities are sold via public offering or private placement. None of our securitizations qualify for sales accounting treatment or as an off-balance sheet arrangement. As a result, the transferred receivables and the associated secured borrowings are included in our Consolidated Balance Sheets and no gain or loss is recorded on the sale. We also act as servicer of transferred receivables. The servicing duties include collecting payments on receivables and preparing monthly investor reports on the performance of the receivables that are used by the trustee to distribute monthly interest and principal payments to investors. While servicing the receivables, we apply the same servicing policies and procedures that are applied to our owned receivables. On a limited basis, we have sold certain receivables to third party lenders, without recourse or future obligations, and generally with no gain or loss. Allowance for Doubtful Accounts An allowance for doubtful accounts is established through a charge to Selling, general and administrative ("SG&A") expenses . The allowance is an estimate of the amount required to absorb probable losses on trade and finance receivables that may become uncollectible. The receivables are charged off when amounts due are determined to be uncollectible. We have two portfolio segments of finance receivables based on the type of financing inherent to each portfolio. The retail portfolio segment represents loans or leases to end-users for the purchase or lease of vehicles. The wholesale portfolio segment represents loans to dealers to finance their inventory. As the initial measurement attributes and the monitoring and assessment of credit risk or the performance of the receivables are consistent within each of our receivable portfolios, we determined that each portfolio consisted of one class of receivable. Impaired receivables are specifically identified and segregated from the remaining portfolio. The expected loss on impaired receivables is fully reserved in a separate calculation as a specific reserve based on the unique ability of the customer to pay the estimated value of the collateral. The historical loss experience and portfolio quality trends of the retail portfolio segment compared to the wholesale portfolio segment are inherently different. A specific reserve on impaired retail receivables is recorded if the estimated fair value of the underlying collateral, net of selling costs, is less than the principal balance of the receivable. We calculate a general reserve on the remaining loan portfolio by applying loss ratios which are determined using actual loss experience and customer payment history, in conjunction with current economic and portfolio quality trends. To establish a specific reserve for impaired wholesale receivables, we consider the same factors discussed above but also consider the financial strength of the dealer and key management, the timeliness of payments, the number and location of satellite locations, the number of dealers of competitor manufacturers in the market area, the type of equipment normally financed, and the seasonality of the business. Repossessions Gains or losses arising from the sale of repossessed collateral supporting finance receivables and operating leases are recognized in Other expense, net . Repossessed assets are recorded within Inventories at the lower of historical cost or fair value, less estimated costs to sell. Inventories Inventories are valued at the lower of cost and net realizable value ("NRV"). Cost is principally determined using the first-in, first-out method. Our gross used truck inventory was $135 million at October 31, 2020 compared to $200 million at October 31, 2019 , offset by reserves of $37 million in both periods. In valuing our used truck inventory, we are required to make assumptions regarding the level of reserves required to value inventories at their NRV. Our judgments and estimates for used truck inventory are based on an analysis of current and forecasted sales prices, aging of and demand for used trucks, and the mix of sales through various market channels. The NRV is subject to change based on numerous conditions, including age, specifications, mileage, timing of sales, market mix and current and forecasted pricing. While calculations are made after taking these factors into account, significant management judgment regarding expectations for future events is involved. Future events that could significantly influence our judgment and related estimates include general economic conditions in markets where our products are sold, actions of our competitors, and the ability to sell used trucks in a timely manner. The following table presents our used truck reserve: For the Years Ended October 31, (in millions) 2020 2019 2018 Balance at beginning of period $ 37 $ 31 $ 110 Additions charged to expense (A) 99 69 50 Deductions/Other adjustments (B) (99 ) (63 ) (129 ) Balance at end of period $ 37 $ 37 $ 31 _________________________ (A) Additions charged to expense reflects the increase of the reserve for inventory on hand. (B) Deductions/Other adjustments include reductions of the reserve related to the sale of units. Property and Equipment We report land, buildings, leasehold improvements, machinery and equipment (including tooling and pattern equipment), furniture, fixtures, and equipment, and equipment leased to others at cost, net of depreciation. We initially record assets under finance lease obligations at the present value of the aggregate future minimum lease payments. We depreciate our assets using the straight-line method over the shorter of the lease term or the estimated useful lives of the assets. The ranges of estimated useful lives are as follows: Years Buildings 20 - 50 Leasehold improvements 3 - 20 Machinery and equipment 3 - 12 Furniture, fixtures, and equipment 3 - 15 Equipment leased to others 1 - 10 Long-lived assets are evaluated periodically to determine if an adjustment to the depreciation and amortization period or to the unamortized balance is warranted. Such evaluation is based principally on the expected utilization of the long-lived assets. We depreciate trucks, tractors, and trailers leased to customers under operating lease agreements on a straight-line basis to the equipment's estimated residual value over the lease term. The residual values of the equipment represent estimates of the value of the assets at the end of the lease contracts and are initially recorded based on estimates of future market values. Realization of the residual values is dependent on our future ability to market the equipment. We review residual values periodically to determine that recorded amounts are appropriate, and the equipment is not impaired. Maintenance and repairs of property and equipment are expensed as incurred. We capitalize replacements and improvements that increase the estimated useful life or productive capacity of an asset and we capitalize interest on major construction and development projects while in progress. Gains or losses on disposition of property and equipment are recognized in Other expense, net . We test for impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying value of an asset or asset group (hereinafter referred to as "asset group") may not be recoverable by comparing the sum of the estimated undiscounted future cash flows expected to result from the operation of the asset group and its eventual disposition to the carrying value. During 2020, we identified a triggering event related to our operations in Brazil due to the impacts of the COVID-19 pandemic, which resulted in declines in actual and forecasted results. We performed an impairment test as of April 30, 2020 on the long-lived assets of the Brazilian asset group. As a result, we recorded impairment charges of $12 million in our Global Operations segment. We also concluded that we had triggering events related to certain trucks under operating leases, due to declines in expected residual values, and certain other long-lived assets. As a result, we recorded charges of $10 million and $6 million , respectively, in our Truck segment. It is reasonably possible that within the next twelve months, we could recognize additional impairment charges for certain trucks under operating leases where Navistar is a lessor, which could be material, if we experience continued declines in excess of our forecasted expected residual values, as a result of the COVID-19 pandemic, the demand for used trucks or a change in the mix of sales through various market channels. During 2019, we identified a triggering event related to continued economic weakness in Brazil and the initiation of strategic cost reduction actions in the Brazilian asset group, which is included in the Global Operations segment. As a result, we estimated the recoverable amount of the asset group and determined that the sum of the undiscounted future cash flows exceeds the carrying value and the asset group was not impaired. For more information regarding asset impairment charges see Note 3, Restructuring, Impairments and Divestitures . Included in equipment leased to others are trucks that we produced or acquired to lease to customers as well as equipment that is financed by Bank of Montreal ("BMO") that does not qualify for revenue recognition, as we retained control of the leased property, which are accounted for as operating leases. In the Consolidated Statement of Cash Flows, the related expenditures are reflected as the Purchases of equipment leased to others in the investing section. Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquired business over the amounts assigned to the net assets. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently, if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that the carrying amount is more likely than not higher than the fair value, goodwill is tested for impairment based on a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, thus the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The income approach is based on discounted cash flows which are derived from internal forecasts and economic expectations for each respective reporting unit. An intangible asset determined to have an indefinite useful life is not amortized until its useful life is determined to no longer be indefinite. Indefinite-lived intangible assets are evaluated each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of the indefinite-lived intangible asset with its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Significant judgment is applied when evaluating if an intangible asset has a finite useful life. In addition, for indefinite-lived intangible assets, significant judgment is applied in testing for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, and incorporating general economic and market conditions. Intangible assets subject to amortization are also evaluated for impairment or when indicators of impairment are determined to exist. We test for impairment of intangible assets, subject to amortization, by comparing the sum of the estimated undiscounted future cash flows expected to result from the operation of the asset group and its eventual disposition to the carrying value. If the sum of the undiscounted future cash flows is less than the carrying value, the fair value of the asset group is determined. The amount of impairment is calculated by subtracting the fair value of the asset group from the carrying value of the asset group. Intangible assets, subject to amortization, could become impaired in the future or require additional charges as a result of declines in profitability due to changes in volume, market pricing, cost, manner in which an asset is used, physical condition of an asset, laws and regulations, or the business environment. We amortize the cost of intangible assets over their respective estimated useful lives, generally on a straight-line basis. The ranges for the amortization periods are generally as follows: Years Customer base and relationships 3 - 15 Trademarks 20 Other 3 - 18 Investments in Non-consolidated Affiliates Equity method investments are recorded at original cost and adjusted periodically to recognize (i) our proportionate share of the investees' net income or losses after the date of investment, (ii) additional contributions made and dividends or distributions received, and (iii) impairment losses resulting from adjustments to fair value. We assess the potential impairment of our equity method investments and determine fair value based on valuation methodologies, as appropriate, including the present value of estimated future cash flows, estimates of sales proceeds, and market multiples. If an investment is determined to be impaired and the decline in value is other than temporary, we record an appropriate write-down. Debt Issuance Costs We amortize debt issuance costs, discounts and premiums over the remaining life of the related debt using the effective interest method. The related income or expense is included in Interest expense . We record debt issuance costs, discounts and premiums associated with term debt as a direct deduction from, or addition to, the face amount of the debt. We record debt issuance costs associated with line-of-credit debt as other assets. Pensions and Postretirement Benefits We use actuarial methods and assumptions to account for our pension plans and other postretirement benefit plans. Pension and other postretirement benefits expense includes the actuarially computed cost of benefits earned during the current service period, the interest cost on accrued obligations, the expected return on plan assets, the straight-line amortization of net actuarial gains and losses and plan amendments, and adjustments due to settlements and curtailments. For more information regarding pension plans and other postretirement benefit plans see Note 12, Postretirement Benefits . Engineering and Product Development Costs Engineering and product development costs arise from ongoing costs associated with improving existing products and manufacturing processes and for the introduction of new truck and engine components and products and are expensed as incurred. Advertising Costs Advertising costs are expensed as incurred and are included in SG&A expenses . These costs totaled $17 million , $31 million , and $31 million for the years ended October 31, 2020 , 2019 , and 2018 , respectively. Contingency Accruals We accrue for loss contingencies associated with outstanding litigation for which we have determined it is probable that a loss occurred and the amount of loss can be reasonably estimated. Our asbestos, product liability, environmental, and workers compensation accruals also include estimated future legal fees associated with the loss contingencies, as we believe we can reasonably estimate those costs. In all other instances, legal fees are expensed as incurred. These expenses may be recorded in Costs of products sold, SG&A expenses, or Other expense, net . These estimates are based on our expectations of the scope, length to complete, and complexity of the claims. In the future, additional adjustments may be recorded as the scope, length, or complexity of outstanding litigation changes. Warranty We generally offer one to five -year warranty coverage for our truck, bus, and engine products, as well as our service parts. Terms and conditions vary by product, customer, and country. We accrue warranty related costs under standard warranty terms and for certain claims outside the contractual obligation period that we choose to pay as accommodations to our customers. Our warranty estimates are established using historical information about the nature, frequency, timing, and average cost of warranty claims. Warranty claims are influenced by numerous factors, including new product introductions, technological developments, the competitive environment, the design and manufacturing process, and the complexity and related costs of component parts. We estimate our warranty accrual for our engines and trucks based on engine types and model years. Our warranty accruals take into account the projected ultimate cost-per-unit ("CPU") utilizing historical claims information. The CPU represents the total cash projected to be spent for warranty claims for a particular model year during the warranty period, divided by the number of units sold. The projection of the ultimate CPU is affected by component failure rates, repair costs, and the timing of failures in the product life cycle. Warranty claims inherently have a high amount of variability in timing and severity and can be influenced by external factors. Our warranty estimation process takes into consideration numerous variables that contribute to the precision of the estimate, but also add to the complexity of the model. Including numerous variables also reduces the sensitivity of the model to any one variable. We perform periodic reviews of warranty spend data to allow for timely consideration of the effects on warranty accruals. Initial warranty estimates for new model year products are based on the previous model year product's warranty experience until the new product progresses sufficiently through its life cycle and related claims data becomes mature. Historically, warranty claims experience for launch-year products has been higher compared to the prior model-year engines; however, over time we have been able to refine both the design and manufacturing process to reduce both the volume and the severity of warranty claims. New product launches require a greater use of judgment in developing estimates until historical experience becomes available. We record adjustments to pre-existing warranties for changes in our estimate of warranty costs for products sold in prior fiscal years. Such adjustments typically occur when claims experience deviates from historic and expected trends. Future events and circumstances could materially change these estimates and require additional adjustments to our liability. When we identify cost effective opportunities to address issues in products sold or corrective actions for safety issues, we initiate product recalls or field campaigns. As a result of the uncertainty surrounding the nature and frequency of product recalls and field campaigns, the liability for such actions is generally recorded when we commit to a product recall or field campaign. Each subsequent quarter after a recall or campaign is initiated the recorded liability balance is analyzed, reviewed, and adjusted if necessary to reflect any changes in the anticipated average cost of repair or number of repairs to be completed prospectively. Included in 2020 warranty expense were $23 million of charges related to new campaign issuances as well as changes in estimates of previously issued campaigns, as compared to $27 million and $10 million in 2019 and 2018 , respectively. The charges were primarily recognized as adjustments to pre-existing warranties. As we continue to identify opportunities to improve the design and manufacturing of our engines we may incur additional charges for product recalls and field campaigns to address identified issues. Optional extended warranty contracts can be purchased for periods ranging from one to ten years. Warranty revenues related to extended warranty contracts are amortized to income, over the life of the contract, (a) in 2020 and 2019 in proportion to the costs expected to be incurred in satisfying the obligation under the contract and (b) in 2018 using the straight-line method. Costs under extended warranty contracts are expensed as

Restructuring and Related Activities [Abstract]
Restructurings and Impairments	Restructuring, Impairments and Divestitures Restructuring charges are recorded based on restructuring plans that have been committed to by management and are, in part, based upon management's best estimates of future events. Changes to the estimates may require future adjustments to the restructuring liabilities. Manufacturing Restructuring Activities We continue to focus on our core Truck and Parts businesses and evaluate our portfolio of assets to validate their strategic and financial fit. This allows us to close or divest non-strategic businesses and identify opportunities to restructure our business and rationalize our Manufacturing operations in an effort to optimize our cost structure. For those areas that fall outside our strategic businesses, we are evaluating alternatives which could result in additional restructuring and other related charges in the future, including but not limited to: (i) impairments, (ii) accelerated depreciation, (iii) costs for employee and contractor termination and other related benefits, and (iv) charges for pension and other postretirement contractual benefits and curtailments. These charges could be significant. During 2020 , we recorded net restructuring charges of $2 million . This includes $7 million of charges due to restructuring activity throughout the organization partially offset by $5 million of benefit related to adjustments on the previously recorded charges in our Global Operations segment. Global Operations restructuring activities During 2019, we ceased production at our MWM Motores engine facility in Jesus Maria, Argentina and initiated structural cost reductions in Brazil. As a result, we recognized charges of $3 million of inventory reserves and other related charges in Costs of products sold and $11 million in Restructuring charges in our Consolidated Statements of Operations in our Global Operations segment. During 2018, we recognized a benefit of $1 million upon the completion of cost-reduction actions impacting our workforce in Brazil. These impacts were recorded in our Global Operations segment within Restructuring charges in our Consolidated Statements of Operations. Asset Impairments During 2020 , we identified a triggering event related to our operations in Brazil due to the impacts of the COVID-19 pandemic, which resulted in declines in actual and forecasted results. We performed an impairment test as of April 30, 2020 on the long-lived assets of the Brazilian asset group. As a result, we recorded charges of $12 million in our Global Operations segment. During 2020 , 2019 and 2018 , we concluded that we had triggering events primarily related to certain trucks under operating leases, due to declines in expected residual values. As a result, we recorded charges of $10 million , $6 million , and $5 million , respectively, in our Truck segment. During 2020 , 2019 and 2018 , we concluded that we had triggering events related to certain long-lived assets. As a result, we recorded charges of $6 million and $1 million in our Truck Segment in 2020 and 2019, respectively, and charges of $6 million and $1 million in our Truck segment and Financial Services segment, respectively, in 2018. During 2018, we concluded that we had triggering events related to the sale of our railcar business in Cherokee, Alabama requiring the impairment of certain long-lived assets. As a result, we recorded a charge of $2 million in our Truck segment. In February 2018, we completed the sale of the business. These charges were recorded in Asset impairment charges in our Consolidated Statements of Operations. See Note 14, Fair Value Measurements , for information on the valuation of impaired operating leases and other assets. Navistar Defense Divestiture In December 2018, we completed the sale of a 70% equity interest in Navistar Defense to an affiliate of Cerberus Capital Management, L.P. In connection with the closing of the transaction, we entered into an exclusive long-term agreement to supply military and commercial parts and chassis to Navistar Defense . We also entered into an intellectual property agreement and a transition services agreement concurrent with the sale. The Navistar Defense purchase price, adjusted for certain calendar year 2018 chargeouts, was approximately $140 million , which was subject to additional adjustments for working capital, transfers of certain liabilities and commitments, and other items. The transaction also included an immaterial amount of additional consideration, not included in the gain on the sale, based on cash proceeds from certain contracts which exceed defined thresholds. During 2019, we recognized a gain on the sale in our Truck segment of $51 million in Other expense, net in our Consolidated Statements of Operations.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Disaggregation of Revenue The following tables disaggregate our external revenue by product type: (in millions) Truck Parts Global Operations Financial Corporate Total Year Ended October 31, 2020 Truck products and services (A) $ 4,590 $ — $ — $ — $ 12 $ 4,602 Truck contract manufacturing 356 — — — — 356 Used trucks 189 — — — — 189 Engines — 198 190 — — 388 Parts 3 1,643 52 — — 1,698 Extended warranty contracts 102 — — — — 102 Sales of manufactured products, net 5,240 1,841 242 — 12 7,335 Retail financing (C) — — — 146 (9 ) 137 Wholesale financing (C) — — — 31 — 31 Finance revenues — — — 177 (9 ) 168 Sales and revenues, net $ 5,240 $ 1,841 $ 242 $ 177 $ 3 $ 7,503 (in millions) Truck Parts Global Operations Financial Corporate Total Year Ended October 31, 2019 Truck products and services (A)(B) $ 7,727 $ — $ — $ — $ 12 $ 7,739 Truck contract manufacturing 399 — — — — 399 Used trucks 257 — — — — 257 Engines — 309 232 — — 541 Parts 5 1,930 77 — — 2,012 Extended warranty contracts 113 — — — — 113 Sales of manufactured products, net 8,501 2,239 309 — 12 11,061 Retail financing (C) — — — 145 (3 ) 142 Wholesale financing (C) — — — 48 — 48 Finance revenues — — — 193 (3 ) 190 Sales and revenues, net $ 8,501 $ 2,239 $ 309 $ 193 $ 9 $ 11,251 ________________________ (A) Includes other markets primarily consisting of Bus, Export Truck and Mexico. (B) Includes military sales of $62 million . In December 2018, we completed the sale of a 70% equity interest in Navistar Defense. See Note 3, Restructuring, Impairments and Divestitures for additional information. (C) Retail financing and Wholesale financing revenues in the Financial Services segment include interest revenue of $58 million and $31 million , respectively, for the year ended October 31, 2020 , and $56 million and $48 million , respectively, for the year ended October 31, 2019 . Trucks, Truck Contract Manufacturing, Used trucks, Engines and Parts Revenue for our Truck products and services, certain Truck contract manufacturing, Used trucks, certain Engines and Parts is recognized at a point in time when control is transferred to the customer. Our Trucks, Used trucks, Engines, and Parts have a standard warranty, the estimated cost of which is included in Costs of products sold . Prior to our sale of a 70% equity interest in Navistar Defense, certain truck sales to the U.S. government of non-commercial products manufactured to government specification were recognized over time as the goods were manufactured. Certain truck and other contract manufacturing arrangements, unrelated to Navistar Defense, continue to be recognized over time. We recognize revenue over time when the finished assets have no alternative use and we have a right to payment for work performed in the event of a contract cancellation or when we create or enhance an asset that the customer controls as it is being created or enhanced. We recognize revenue using a cost-based input method because it best depicts our progress in satisfying the performance obligation. The selection of the method requires judgement and is based on the nature of the products or services to be provided. Certain terms or modifications to U.S. and foreign government contracts may have been unpriced; that is, the work to be performed was defined, but the related contract price was to be negotiated at a later date. In situations where we could reliably estimate a profit margin in excess of costs incurred, revenue and gross margin were recorded for delivered contract items. Otherwise, revenue was recognized when the price had been agreed with the applicable government and costs were deferred when it was probable that the costs would be recovered. An allowance for parts sales returns is recorded as a reduction to revenue based upon estimates using historical information about returns. This includes when we are a reseller of certain service parts that include a core component. A core component is the basic forging or casting, such as an engine block, that can be remanufactured by a certified remanufacturing supplier. When a dealer returns a core component within the specified eligibility period, we refund the core return deposit, which is applied to the customer's account balance. Extended Warranty Contracts We sell separately-priced extended warranty contracts that can be purchased for periods ranging from one to ten years. Warranty revenue related to extended warranty contracts is recognized over the life of the contract in proportion to the costs expected to be incurred in satisfying the obligation under the contract. Costs under extended warranty contracts are expensed as incurred. We recognize losses on defined pools of extended warranty contracts when the remaining expected costs for a given pool of contracts exceed the related deferred revenue. Retail and Wholesale Financing Financial Services operations recognize revenue from retail notes, finance leases, wholesale notes, retail accounts, and wholesale accounts as Finance revenues over the term of the receivables utilizing the effective interest method. Certain direct origination costs and fees are deferred and recognized as adjustments to yield and are reported as part of interest income over the life of the receivable. Loans are impaired when we conclude it is probable the customer will not be able to make full payment according to contractual terms after reviewing the customer's financial performance, payment ability, capital-raising potential, management style, economic situation, and other factors. The accrual of interest on such loans is suspended when the loan becomes 90 days or more past due. Finance revenues on these loans are recognized only to the extent cash payments are received. We resume accruing interest on these accounts when payments are current according to the terms of the loans and future payments are reasonably assured. Operating lease revenues are recognized on a straight-line basis over the life of the lease. Recognition of revenue is suspended when management determines the collection of future revenue is not probable. Recognition of revenue is resumed if collection again becomes probable. Performance Obligations Generally, revenue from our sales is recognized at a point in time when control is transferred to the customer which generally occurs upon shipment from our plants and distribution centers or at the time of delivery to our customers. The standard payment term is less than 30 days, but we may extend payment terms on selected receivables. We have elected the practical expedient that allows us to not assess whether a contract has a significant financing component when the time between cash collection and transfer of control is less than one year. We recognize price allowances, returns and the cost of incentive programs in the normal course of business based on programs offered to dealers or fleet customers. Estimates are made for sales incentives on certain vehicles in dealer stock inventory based on historical experience and announced special programs. The estimated sales incentives and returns are adjusted at the earlier of when the estimate of consideration we expect to receive changes or the consideration becomes fixed. For contracts where there is more than one performance obligation, discounts are allocated to all of the performance obligations in the contract based on their relative standalone selling prices. Truck sales arrangements with U.S. fleet customers are often complex and non-standard, and may include pricing allowances and other sales incentives, such as rebates, financing incentives, trade allowances and residual value guarantees, for which losses are generally capped. Truck sales to fleet customers are recognized in accordance with the terms of each contract. In certain arrangements, the evaluation of financing incentives and residual value guarantees may result in the transaction being recorded as an operating lease, as we retain control in the leased property. Concurrent with our recognition of revenue, we recognize price allowances and the cost of incentive programs in the normal course of business based on programs offered to our fleet customers. Revenue on bill and hold arrangements is not recognized until after the customer is notified that the product (i) has been completed according to customer specifications, (ii) has passed our quality control inspections, (iii) is ready for physical transfer to the customer and (iv) the reason for the bill and hold arrangement is substantive. We have elected to account for shipping and handling activities that occur subsequent to transfer of control as a fulfillment cost and not as a separate performance obligation. The costs are recognized as an expense in Costs of products sold when control of the related performance obligation has transferred to the customer. We do not disclose the transaction price related to order backlogs as they have an original expected duration of less than one year. We exclude from revenue any sales taxes, value added taxes and other related taxes collected from customers. The impact of changes to revenue related to performance obligations satisfied in prior periods was not material to our consolidated financial statements in 2020. Contract Balances Most of our contracts are for a period of less than one year. We have certain long-term contract manufacturing and extended warranty contracts that extend beyond one year. We record deferred revenue, primarily related to extended warranty contracts, when we receive consideration from a customer prior to transferring goods or services under the terms of a sales contract. This deferred revenue represents contract liabilities which are included in our Consolidated Balance Sheets as components of current and long-term liabilities. The amount of manufacturing contract liabilities as of October 31, 2020 is not material to our consolidated financial statements. The amount of deferred revenue related to extended warranty programs was $245 million , $279 million , and $255 million at October 31, 2020 , 2019 , and 2018 , respectively. Revenue recognized under our extended warranty programs was $101 million , $113 million , and $104 million for the years ended October 31, 2020 , 2019 , and 2018 , respectively. We expect to recognize revenue under our extended warranty programs of approximately $89 million in 2021, $73 million in 2022, $45 million in 2023, $23 million in 2024, $8 million in 2025 and an aggregate amount of $7 million thereafter. Contract Costs We recognize incremental costs to obtain contracts as an asset if they are recoverable. As a practical expedient, we recognize the costs of obtaining a contract as an expense when the related contract period is less than one year. We had no contract costs capitalized as of October 31, 2020 and 2019 .

Finance Receivables

Receivables [Abstract]
Finance Receivables	Finance Receivables Finance receivables are receivables of our Financial Services operations. Finance receivables generally consist of wholesale notes and accounts, as well as retail notes, finance leases and accounts. Total finance receivables reported on the Consolidated Balance Sheets are net of an allowance for doubtful accounts. Total assets of our Financial Services operations net of intercompany balances were $2.2 billion and $2.8 billion as of October 31, 2020 and 2019 , respectively. Included in total assets of our Financial Services operations are finance receivables of $1.6 billion and $2.2 billion as of October 31, 2020 and 2019 , respectively. We have two portfolio segments of finance receivables that we distinguish based on the type of customer and nature of the financing inherent to each portfolio. The retail portfolio segment represents loans or leases to end-users for the purchase or lease of vehicles. The wholesale portfolio segment represents loans to dealers to finance their inventory. In connection with the COVID-19 pandemic, we have received extension requests from certain customers in the retail note and finance lease portfolios. These requests were generally granted for short-term extensions (6 months or less), without interest or principal forgiveness. The related credit exposure was not material to the consolidated financial statements. We will continue to monitor our portfolios in light of the ongoing economic uncertainties resulting from the COVID-19 pandemic. We may offer additional extensions and modifications to customers going forward in order to maximize the recoverability of outstanding receivable balances. Our Finance receivables, net in our Consolidated Balance Sheets consist of the following: As of October 31, (in millions) 2020 2019 Retail portfolio $ 622 $ 854 Wholesale portfolio 1,025 1,366 Total finance receivables 1,647 2,220 Less: Allowance for doubtful accounts 25 23 Total finance receivables, net 1,622 2,197 Less: Current portion, net (A) 1,371 1,923 Noncurrent portion, net $ 251 $ 274 _________________________ (A) The current portion of finance receivables is computed based on contractual maturities. Actual cash collections typically vary from the contractual cash flows because of prepayments, extensions, delinquencies, credit losses, and renewals. As of October 31, 2020 , contractual maturities of our finance receivables are as follows: (in millions) Retail Portfolio Wholesale Portfolio Total Due in: 2021 $ 384 $ 1,025 $ 1,409 2022 133 — 133 2023 87 — 87 2024 49 — 49 2025 19 — 19 Thereafter 4 — 4 Gross finance receivables 676 1,025 1,701 Less: Unearned finance income 54 — 54 Total finance receivables $ 622 $ 1,025 $ 1,647 Securitizations Our Financial Services operations transfer wholesale notes, retail accounts receivable, finance leases, and operating leases to special purpose entities ("SPEs"), which generally are only permitted to purchase these assets, issue asset-backed securities, and make payments on the securities issued. In addition to servicing receivables, our continued involvement in the SPEs may include an economic interest in the transferred receivables and, in some cases, managing exposure to interest rate changes on the securities using interest rate swaps or interest rate caps. There were no transfers of finance receivables that qualified for sale accounting treatment as of October 31, 2020 and 2019 , and as a result, the transferred finance receivables are included in our Consolidated Balance Sheets and the related interest earned is included in Finance revenues . We transfer eligible finance receivables into trusts in order to issue asset-backed securities. These trusts are VIEs of which we are determined to be the primary beneficiary and, therefore, the assets and liabilities of the trusts are included in our Consolidated Balance Sheets . The outstanding balance of finance receivables transferred into these VIEs was $649 million and $874 million as of October 31, 2020 and 2019 , respectively. Other finance receivables related to secured transactions that do not qualify for sale accounting treatment were $182 million and $358 million as of October 31, 2020 and 2019 , respectively. For more information on assets and liabilities of consolidated VIEs and other securitizations accounted for as secured borrowings by our Financial Services segment, see Note 1, Summary of Significant Accounting Policies. Finance Revenues The following table presents the portion of Finance revenues from our Financial Services segment: As of October 31, (in millions) 2020 2019 2018 Retail notes and finance leases revenue $ 63 $ 60 $ 50 Wholesale notes interest 59 118 105 Operating lease revenue 85 86 72 Retail and wholesale accounts interest 10 33 30 Gross finance revenues 217 297 257 Less: Intercompany revenues 40 104 97 Finance revenues $ 177 $ 193 $ 160

Allowance for Doubtful Accounts [Abstract]
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Our two finance receivables portfolio segments, retail and wholesale, each consist of one class of receivable based on: (i) initial measurement attributes of the receivables, and (ii) the assessment and monitoring of risk and performance of the receivables. For more information, see Note 4, Finance Receivables . The following tables present the activity related to our allowance for doubtful accounts for our retail portfolio segment, wholesale portfolio segment, and trade and other receivables: For the Year Ended October 31, 2020 (in millions) Retail Wholesale Trade and Total Allowance for doubtful accounts, at beginning of period $ 20 $ 3 $ 21 $ 44 Provision for doubtful accounts 12 (1 ) 5 16 Charge-offs (9 ) — (2 ) (11 ) Recoveries 1 — — 1 Other (A) (1 ) — (5 ) (6 ) Allowance for doubtful accounts, at end of period $ 23 $ 2 $ 19 $ 44 For the Year Ended October 31, 2019 (in millions) Retail Wholesale Trade and Total Allowance for doubtful accounts, at beginning of period $ 19 $ 3 $ 28 $ 50 Provision for doubtful accounts 5 — (1 ) 4 Charge-offs (6 ) — (6 ) (12 ) Recoveries 2 — — 2 Allowance for doubtful accounts, at end of period $ 20 $ 3 $ 21 $ 44 For the Year Ended October 31, 2018 (in millions) Retail Portfolio Wholesale Portfolio Trade and Other Receivables Total Allowance for doubtful accounts, at beginning of period $ 17 $ 3 $ 28 $ 48 Provision for doubtful accounts 7 — 3 10 Charge-offs (7 ) — (1 ) (8 ) Recoveries 3 — — 3 Other (A) (1 ) — (2 ) (3 ) Allowance for doubtful accounts, at end of period $ 19 $ 3 $ 28 $ 50 ____________________ (A) Amounts include impact from currency translation. The accrual of interest income is suspended on certain impaired finance receivables. Impaired finance receivables include accounts with specific loss reserves and certain accounts that are on non-accrual status. We may continue to collect payments on our impaired finance receivables.

See Note 14, Fair Value Measurements , for information on the valuation of impaired finance receivables. In response to the COVID-19 pandemic, we have granted limited payment extensions to certain customers who were not past due before the pandemic. There was no forgiveness of principal or interest in connection with these extensions. As a result, we concluded that these extensions were not troubled debt restructurings ("TDR"). We have TDRs in the normal course of our Financial Services operations; however, such amounts are not material. We use the aging of our receivables as well as other inputs when assessing credit quality.

Leases [Abstract]
Leases	Leases We account for a lease when an asset has been identified and when the contract conveys the right to control the use of the identified asset in exchange for consideration for a period of time. We determine whether an arrangement is or contains a lease at inception. Lessee We lease certain land, buildings, and equipment under operating and finance leases for our distribution centers, manufacturing facilities and our corporate offices, expiring at various dates through 2030. Operating leases generally have 1 to 20 year terms, with options to extend the lease. Terms are generally negotiated at the time of renewal. Options to terminate are not common and may be included at the discretion of the lessor. Certain leases may include provisions for rent escalation based on actual costs incurred by the lessor. Variable lease payments, which are not material, are not included as right of use assets or lease liabilities in our Consolidated Balance Sheets and are expensed as incurred. Generally, our lease agreements do not contain any residual value guarantees or restrictive covenants. All real estate leases and equipment leases, with an initial term greater than 12 months, result in the recognition of a right of use asset and lease liability recognized on our Consolidated Balance Sheets . Certain equipment leases with a term less than 12 months do not result in the recognition of right of use assets or lease liabilities. We recognize lease expense for those leases, which are not material, on a straight-line basis over the lease term. We sublease certain real estate to third parties. Rental income from subleases for the years ended October 31, 2020 , 2019 and 2018 was $3 million , $3 million and $5 million , respectively. We generally combine fixed lease and non-lease components for those leases we have entered into or reassessed after the adoption of the new lease standard. These assets primarily include real estate, manufacturing equipment and vehicles. The implicit rate of the majority of our leases is not known; therefore, we use our incremental borrowing rate in determining the present value of lease payments. For leases denominated in a foreign currency, the incremental borrowing rate is adjusted by replacing the U.S. credit-free spread with that of the specific country. For the year ended October 31, 2020 , we incurred operating lease costs recorded in Costs of products sold of $9 million and operating lease costs recorded in SG&A expenses of $25 million . These charges were recognized in our Consolidated Statements of Operations . Finance lease costs were not material to our Consolidated Statements of Operations .

These leases are classified as either operating or finance leases, expire at various dates, and typically have terms which allow an extension or fair value options to purchase the asset at the end of the lease term. The terms of leases generally range from 2 to 7 years, though extension periods may be for a shorter time. Our Financial Services segment manages the relationship with Navistar Capital (a program of BMO Harris Bank N.A. and Bank of Montreal (together, “BMO”)). Navistar Capital is our third-party preferred source of retail and lease customer financing for equipment offered by us and our dealers in the U.S. For certain Navistar Capital financed contracts which contain an end of term option for us to purchase the leased equipment if the customer declines to do so, we recognize the equipment subject to an operating lease as an asset on our Consolidated Balance Sheets . For more information related to the BMO arrangement, see Note 15, Commitments and Contingencies . We have also leased certain real estate to third parties to manage excess capacity through our Corporate segment. We depreciate trucks, tractors, and trailers leased to customers under operating lease agreements on a straight-line basis to the equipment's estimated residual value over the lease term. The residual values of the equipment leased under operating lease agreements represent estimates of the value of the assets at the end of the lease contracts and are initially recorded based on estimates of future market values. Realization of the residual values is dependent on our future ability to market the equipment. We work with our customers and dealers to manage the sale of lease returns and the recovery of residual exposure. We also review residual values periodically to determine that recorded amounts are appropriate and the equipment is not impaired. For more information on key inputs and valuation methodologies in evaluating impairment of assets under operating lease agreements, see Note 14, Fair Value Measurements . For more information regarding impaired finance receivables see Note 5, Allowance for Doubtful Accounts , and Note 3, Restructuring, Impairments and Divestitures for impaired assets under operating leases.

We determine whether an arrangement is or contains a lease at inception. Lessee We lease certain land, buildings, and equipment under operating and finance leases for our distribution centers, manufacturing facilities and our corporate offices, expiring at various dates through 2030. Operating leases generally have 1 to 20 year terms, with options to extend the lease. Terms are generally negotiated at the time of renewal. Options to terminate are not common and may be included at the discretion of the lessor. Certain leases may include provisions for rent escalation based on actual costs incurred by the lessor. Variable lease payments, which are not material, are not included as right of use assets or lease liabilities in our Consolidated Balance Sheets and are expensed as incurred. Generally, our lease agreements do not contain any residual value guarantees or restrictive covenants. All real estate leases and equipment leases, with an initial term greater than 12 months, result in the recognition of a right of use asset and lease liability recognized on our Consolidated Balance Sheets . Certain equipment leases with a term less than 12 months do not result in the recognition of right of use assets or lease liabilities. We recognize lease expense for those leases, which are not material, on a straight-line basis over the lease term. We sublease certain real estate to third parties. Rental income from subleases for the years ended October 31, 2020 , 2019 and 2018 was $3 million , $3 million and $5 million , respectively. We generally combine fixed lease and non-lease components for those leases we have entered into or reassessed after the adoption of the new lease standard. These assets primarily include real estate, manufacturing equipment and vehicles. The implicit rate of the majority of our leases is not known; therefore, we use our incremental borrowing rate in determining the present value of lease payments. For leases denominated in a foreign currency, the incremental borrowing rate is adjusted by replacing the U.S. credit-free spread with that of the specific country. For the year ended October 31, 2020 , we incurred operating lease costs recorded in Costs of products sold of $9 million and operating lease costs recorded in SG&A expenses of $25 million . These charges were recognized in our Consolidated Statements of Operations . Finance lease costs were not material to our Consolidated Statements of Operations .

These leases are classified as either operating or finance leases, expire at various dates, and typically have terms which allow an extension or fair value options to purchase the asset at the end of the lease term. The terms of leases generally range from 2 to 7 years, though extension periods may be for a shorter time. Our Financial Services segment manages the relationship with Navistar Capital (a program of BMO Harris Bank N.A. and Bank of Montreal (together, “BMO”)). Navistar Capital is our third-party preferred source of retail and lease customer financing for equipment offered by us and our dealers in the U.S. For certain Navistar Capital financed contracts which contain an end of term option for us to purchase the leased equipment if the customer declines to do so, we recognize the equipment subject to an operating lease as an asset on our Consolidated Balance Sheets . For more information related to the BMO arrangement, see Note 15, Commitments and Contingencies . We have also leased certain real estate to third parties to manage excess capacity through our Corporate segment. We depreciate trucks, tractors, and trailers leased to customers under operating lease agreements on a straight-line basis to the equipment's estimated residual value over the lease term. The residual values of the equipment leased under operating lease agreements represent estimates of the value of the assets at the end of the lease contracts and are initially recorded based on estimates of future market values. Realization of the residual values is dependent on our future ability to market the equipment. We work with our customers and dealers to manage the sale of lease returns and the recovery of residual exposure. We also review residual values periodically to determine that recorded amounts are appropriate and the equipment is not impaired. For more information on key inputs and valuation methodologies in evaluating impairment of assets under operating lease agreements, see Note 14, Fair Value Measurements . For more information regarding impaired finance receivables see Note 5, Allowance for Doubtful Accounts , and Note 3, Restructuring, Impairments and Divestitures for impaired assets under operating leases.

Under the terms of the Term Loan Credit Agreement, the interest rate on the outstanding loan is based, at our option, on an adjusted Eurodollar Rate, plus a margin of 3.50% , or a Base Rate, plus a margin of 2.50% . The Term Loan Credit Agreement requires quarterly amortization payments of $4 million with the balance due at maturity on November 6, 2024. A portion of the proceeds from the Term Loan Credit Agreement was used to repay all outstanding loans under our previously existing Senior Secured Term Loan Credit Facility ("Term Loan"), to redeem a portion of the previously outstanding 8.25% senior notes ("8.25% Senior Notes") and to pay accrued and unpaid interest thereon, and pay certain transaction fees and expenses incurred in connection with the new Term Loan Credit Agreement. Upon the repayment of the Term Loan in the first quarter of 2018, we recorded approximately $16 million of charges related to the extinguishment of unamortized debt issuance costs associated with the Term Loan, included in Other expense, net on our Consolidated Statements of Operations. 9.5% Senior Secured Notes, due 2025 On April 27, 2020, we issued $600 million aggregate principal amount of 9.5% senior secured notes, due 2025 ("9.5% Senior Secured Notes"). Interest is payable on May 1 and November 1 of each year beginning on November 1, 2020 until the maturity date of May 1, 2025. The proceeds from the 9.5% Senior Secured Notes are being used for general corporate purposes in addition to certain transaction fees and expenses incurred in connection with the new 9.5% Senior Secured Notes. Debt issuance costs of $12 million were recorded as a direct deduction from the carrying amount and will be amortized through Interest expense over the life. The 9.5% Senior Secured Notes are subject to specific redemption pricing, restrictive payments, and change of control provisions. 6.625% Senior Notes On November 6, 2017, we issued $1.1 billion in aggregate principal amount of 6.625% senior notes, due 2026 (" 6.625% Senior Notes"). Interest is payable on the 6.625% Senior Notes on May 1 and November 1 of each year beginning on May 1, 2018 until the maturity date of November 1, 2025. The proceeds from the 6.625% Senior Notes offering were used to redeem a portion of our previously existing 8.25% Senior Notes, to pay accrued and unpaid interest thereon, and pay the associated prepayment premiums, certain transaction fees and expenses incurred in connection with the new 6.625% Senior Notes. Upon the redemption of the 8.25% Senior Notes balance of $1.45 billion in the first quarter of 2018, we recorded approximately $30 million of charges related to the extinguishment of unamortized debt issuance costs and tender premiums associated with the 8.25% Senior Notes, included in Other expense, net on our Consolidated Statements of Operations. Loan Agreement related to the Tax-Exempt Bonds and Recovery Zone Facility Revenue Refunding Bonds On November 6, 2017, there was an amendment to the Tax-Exempt Bonds that increased the interest rate to 6.75% and granted of a junior priority lien on certain collateral securing the Company's Term Loan Credit Agreement. We entered into the First Amendment to Loan Agreement with The County of Cook, Illinois and the First Amendment to Loan Agreement with the Illinois Finance Authority (“Tax-Exempt Bond Amendments”) to adjust various covenants included in the loan agreements relating to the Tax-Exempt Bonds, including to permit the Company to incur secured debt up to $1.7 billion , in exchange for a coupon increase from 6.50% to 6.75% and the grant of a junior priority lien on certain collateral securing the Company’s Term Loan Credit Agreement. The Tax-Exempt Bonds were repaid on October 15, 2020 using the proceeds from the 2020 Bonds (as defined below). The early repayment of these Tax-Exempt Bonds resulted in the write off of unamortized debt issuance costs of $5 million . On August 4, 2020, we completed a certain tax-exempt bond refinancing in which the Illinois Finance Authority (the “IFA”) issued and sold $225 million aggregate principal amount of Recovery Zone Facility Revenue Refunding Bonds (Navistar International Corporation Project) Series 2020 due October 15, 2040 ("the 2020 Bonds"). The proceeds from the issuance of the 2020 Bonds were used, together with certain other funds of the Company, for the purposes of refunding (1) the $135 million aggregate principal amount of IFA Recovery Zone Facility Revenue bonds (Navistar International Corporation Project), Series 2010 due October 15, 2040 and (2) $90 million aggregate principal amount of The County Cook, Illinois Recovery Zone Facility Revenue Bonds (Navistar International Corporation Project), Series 2010 due October 15, 2040 (collectively the "2010 Bonds") on October 15, 2020. The interest rate on the 2020 Bonds is 4.75%. The 2020 Bonds were issued pursuant to an indenture of trust and the proceeds of the 2020 Bonds were loaned by IFA to the Company pursuant to a loan agreement and promissory note, each dated as of July 1, 2020. The payment of principal and interest on the 2020 Bonds is guaranteed under a guarantee issued by NI. The 2020 Bonds are special, limited obligations of the IFA, payable out of the revenues and income derived under the related loan agreement, promissory note and guarantee. Beginning on August 1, 2030, the 2020 Bonds are subject to optional redemption at the direction of the Company, in whole or in part. In addition, if the Company is acquired by TRATON SE or one of its affiliates, the Company may, at its option, redeem all, but not less than all, of the 2020 Bonds. In each case, the Company will pay a redemption price equal to 100% of the principal amount thereof, plus accrued interest, if any, to the redemption date. The 2020 Bonds are senior unsecured general obligations with a subsidiary guaranty from NI. Financed Lease Obligations Prior to the adoption of ASC 842, we accounted for as borrowings certain third-party equipment financings by BMO (as defined in Note 15, Commitments and Contingencies ), our preferred source of retail customer financing for equipment offered by us and our dealers in the U.S. The initial transactions did not qualify for revenue recognition as we retained control of the leased property. As a result, the proceeds from the transfers were recorded as a financed lease obligation and amortized to revenue over the term of the financing. The remaining obligation will be amortized through 2024 , with interest rates ranging from 3.77% to 5.91% . Amended and Restated Asset-Based Credit Facility We have a $125 million asset-based credit facility ("Amended and Restated Asset-Based Credit Facility") which has a maturity date of August 2022. The borrowing base of the revolving facility is secured by a first priority security interest in certain of NI's aftermarket parts inventory locations and contains customary covenants, representations and warranties. Our borrowing capacity is subject to a $13 million liquidity block and is impacted by outstanding standby letters of credit issued under this facility and the amount of eligible inventory. Borrowings under the Amended and Restated Asset-Based Credit Facility accrue interest at a rate equal to a base rate or an adjusted LIBOR rate plus a spread. The spread is 175 basis points for Base Rate borrowings and 275 basis points for LIBOR borrowings . As of October 31, 2020 and 2019 , we had no borrowings outstanding but did have availability to borrow under the Amended and Restated Asset-Based Credit Facility. Amounts borrowed under this facility for the twelve months ended October 31, 2020 were $60 million . Repayments under this facility for the twelve months ended October 31, 2020 , were $60 million . These borrowings and repayments are classified under the line item Net change in secured revolving credit facilities in the Consolidated Statements of Cash Flows . There were no borrowings or repayments in the years ended 2019 and 2018 . Financial Services Operations Asset-backed Debt In December 2017, the maturity date of the variable funding notes ("VFN") facility was extended from May 2018 to December 2018, and the maximum capacity was reduced from $425 million to $350 million . In November 2018, the maturity of the VFN facility was extended from December 2018 to May 2020. In April 2019, the VFN facility capacity was temporarily increased from $350 million to $550 million until the earlier of June 28, 2019, or the completion of a qualifying wholesale asset-backed term facility. In June 2019, the capacity decreased from $550 million to $350 million , upon the sale of $300 million of two-year investor notes by Navistar Financial Securities Corporation ("NFSC"). Proceeds were used, in part, to replace the $250 million of investor notes that matured in June 2019. In May 2020, the maturity date of the VFN facility was extended to May 2021, and the maximum capacity remained $350 million. The VFN facility and investor notes are secured by assets of the wholesale note owner trust. Amounts borrowed under this facility for the twelve months ended October 31, 2020 , 2019 and 2018 were $300 million , $1,495 million and $590 million , respectively. Repayments under this facility for the twelve months ended October 31, 2020 , 2019 and 2018 were $515 million , $1,540 million and $455 million , respectively. These borrowings and repayments are classified under the line item Net change in secured revolving credit facilities in the Consolidated Statements of Cash Flows . In September 2018, NFSC issued $300 million of two-year investor notes secured by assets of the wholesale note owner trust. Proceeds were used, in part, to replace the $300 million of investor notes that matured in September 2018. In July 2020, NFSC issued $300 million of two-year investor notes secured by assets of the wholesale note owner trust. Proceeds were used, in part, to replace the $300 million of NFSC investor notes that matured in September 2020. Our Mexican financial services affiliate, Navistar Financial, S.A. de C.V., Sociedad Financiera de Objeto Multiple, Entidad Regulada ("NFM"), issues secured notes, denominated in Mexican pesos, which are secured by retail finance receivables. The aggregate balance of these notes was zero and $13 million , net of issuance costs, at October 31, 2020 , and 2019 , respectively. In January 2018, Truck Retail Accounts Corporation ("TRAC"), a special purpose, wholly-owned subsidiary of NFC, extended its one-year $100 million revolving facility from April 2018 to January 2019, and in December 2018, the maturity was further extended to January 2020. In April 2019, the maximum capacity of the TRAC funding facility was increased from $100 million to $150 million , and further increased to $200 million in October 2019. In January 2020, the TRAC funding facility was renewed and extended to June 2021, with a capacity range of $100 million to $200 million. Borrowings under this facility are secured by eligible retail accounts receivable. Amounts borrowed under this facility for the twelve months ended October 31, 2020 , 2019 and 2018 were $294 million , $800 million and $336 million , respectively. Repayments under this facility for the twelve months ended October 31, 2020 , 2019 and 2018 were $334 million , $743 million and $336 million , respectively. These borrowings and repayments are classified under the line item Net change in secured revolving credit facilities in the Consolidated Statements of Cash Flows . The majority of the above asset-backed debt is issued by consolidated SPEs and is payable out of collections on the finance receivables sold to the SPEs. This debt is the legal obligation of the SPEs and not NFC or NFM. Assets used as collateral include finance receivables, restricted cash and other assets. The carrying amount of the assets used as collateral for asset-backed debt were $1.1 billion and $1.3 billion at October 31, 2020 and 2019 , respectively. See Note 4, Finance Receivables , for more information on finance receivables used to secure asset-backed debt. NFC Term Loan and Bank Credit Facilities On June 1, 2018, in accordance with the terms of the May 2016 amended and extended NFC bank credit facility, the term loan portion was paid in full and the revolving portion capacity was reduced from $275 million to $269 million . On June 12, 2018, certain leverage covenants and baskets under the NFC bank credit facility were amended to allow for completion of the senior secured NFC term loan ("NFC Term Loan") in July 2018. In May 2019, NFC increased the capacity of its revolving bank credit facility from $269 million to $748 million and extended the maturity from September 2021 to May 2024. The additional capacity was used to fully repay the NFC Term Loan balance of $398 million . The early repayment of the NFC Term Loan resulted in the write off of unamortized debt issuance costs and discount of $6 million . The borrowings on the revolving portion of the facility totaled $538 million and $623 million as of October 31, 2020 and 2019 , respectively. We borrow funds under various bank credit lines denominated in U.S. dollars and Mexican pesos to be used for investment in our Mexican financial services operations. As of October 31, 2020 , borrowings outstanding under these arrangements were $402 million , of which 20% was denominated in U.S. dollars and 80% in Mexican pesos. As of October 31, 2019 , borrowings outstanding under these arrangements were $437 million , of which 11% was denominated in U.S. dollars and 89% in Mexican pesos. The interest rates on the dollar-denominated debt are at a negotiated fixed rate or at a variable rate based on LIBOR, and the interest rates on peso-denominated debt are based on the Interbank Interest Equilibrium Rate. Commercial Paper Effective February 2017, our Mexican financial services operation entered into a five-year commercial paper program for up to P 1.8 billion (the equivalent of approximately $84 million at October 31, 2020 ). In October 2018, the commercial paper program was increased to P 3.0 billion (the equivalent of approximately $140 million at October 31, 2020 ). Borrowings Secured by Operating and Finance Leases International Truck Leasing Corporation ("ITLC"), a special purpose, wholly-owned subsidiary of NFC, provides NFC with another source to obtain borrowings secured by leases. The balances are classified under Financial Services operations debt as borrowings secured by leases. ITLC's assets are available to satisfy its creditors' claims prior to such assets becoming available for ITLC's use or to NFC or affiliated companies. For the years ended October 31, 2020 and 2019 , ITLC issued new borrowings of $61 million and $31 million , respectively. The balance of these secured borrowings issued by ITLC totaled $117 million and $91 million as of October 31, 2020 and 2019 , respectively. The carrying amount of assets used as collateral was $144 million and $109 million as of October 31, 2020 and 2019 , respectively. ITLC does not have any unsecured debt. For the years ended October 31, 2020 and 2019 , NFC issued new borrowings secured by leases of $28 million and $31 million , respectively. The balance of these secured borrowings issued by NFC totaled $53 million and $31 million as of October 31, 2020 and 2019 , respectively. The carrying amount of assets used as collateral was $51 million and $30 million as of October 31, 2020 and 2019 , respectively. Future Maturities The aggregate contractual annual maturities for debt as of October 31, 2020 , are as follows: Manufacturing Financial Total (in millions) 2021 $ 45 $ 595 $ 640 2022 28 432 460 2023 27 211 238 2024 18 597 615 2025 616 3 619 Thereafter 2,801 — 2,801 Total debt 3,535 1,838 5,373 Less: Unamortized discount and unamortized debt issuance costs 39 4 43 Net debt $ 3,496 $ 1,834 $ 5,330 Debt and Lease Covenants We have certain public and private debt agreements, including the Term Loan Credit Agreement, the 9.5% Senior Secured Notes, the 6.625% Senior Notes, the loan agreements for the 2020 Bonds, and the Amended and Restated Asset-Based Credit Facility, which limit our ability to incur additional indebtedness, pay dividends, buy back our stock, and take other actions. As of October 31, 2020 , we were in compliance with these covenants. We are also required under certain agreements with public and private lenders of NFC to ensure that NFC and its subsidiaries maintain their income before interest expense and income taxes at not less than 125% of their total interest expense. Under these agreements, if NFC's consolidated income, including capital contributions made by NIC or NI, before interest expense and income taxes is less than 125% of its interest expense, NIC or NI must make payments to NFC to achieve the required ratio. During the years ended October 31, 2020 , 2019 , and 2018 , no such payments were made. Covenants of the NFC bank credit facility restrict or limit certain payments such as dividends paid to NI. NFC was able to pay dividends of $30 million and $20 million to NI for the years ended October 31, 2020 and 2019 , respectively, within the limits of these covenants. In the year ended October 31, 2018, NFC paid no dividends. Our Mexican financial services operations also have debt covenants, which require the maintenance of certain financial ratios. As of October 31, 2020 , we were in compliance with those covenants.

Retirement Benefits [Abstract]
Postretirement Benefits	Postretirement Benefits Defined Benefit Plans We provide postretirement benefits to a substantial portion of our employees and retirees. Costs associated with postretirement benefits include pension and postretirement health care expenses for employees, retirees, surviving spouses and dependents. Obligations and Funded Status A summary of the changes in benefit obligations and plan assets is as follows: Pension Benefits Health and Life (in millions) 2020 2019 2020 2019 Change in benefit obligations Benefit obligations at beginning of year $ 3,347 $ 3,344 $ 1,087 $ 1,245 Service cost 8 7 3 3 Interest on obligations 84 121 28 49 Actuarial loss (gain) 64 405 (457 ) (138 ) Plan amendment — 4 — — Settlements (11 ) (263 ) — — Currency translation (1 ) (5 ) — — Plan participants' contributions — — 37 35 Subsidy receipts — — 37 37 Benefits paid (249 ) (266 ) (136 ) (144 ) Benefit obligations at end of year $ 3,242 $ 3,347 $ 599 $ 1,087 Change in plan assets Fair value of plan assets at beginning of year $ 2,013 $ 2,162 $ 283 $ 297 Actual return on plan assets 58 232 7 20 Settlements (11 ) (263 ) — — Currency translation (1 ) (5 ) — — Employer contributions (A) 35 136 1 1 Benefits paid (233 ) (249 ) (39 ) (35 ) Fair value of plan assets at end of year $ 1,861 $ 2,013 $ 252 $ 283 Funded status at year end $ (1,381 ) $ (1,334 ) $ (347 ) $ (804 ) _________________________ (A) Employer contributions as of October 31, 2019 consisted of $140 million , net of a $4 million return of plan assets to the Company. Pension Benefits Health and Life (in millions) 2020 2019 2020 2019 Amounts recognized in our Consolidated Balance Sheets consist of: Noncurrent asset $ 5 $ 3 $ — $ — Current liability (18 ) (18 ) (10 ) (20 ) Noncurrent liability (1,368 ) (1,319 ) (337 ) (784 ) Net liability recognized $ (1,381 ) $ (1,334 ) $ (347 ) $ (804 ) Amounts recognized in our accumulated other comprehensive loss consist of: Net actuarial loss (gain) $ 2,133 $ 2,086 $ (478 ) $ (33 ) Net prior service cost 3 4 — — Net amount recognized $ 2,136 $ 2,090 $ (478 ) $ (33 ) The underfunded status of our pension plans on a U.S. GAAP basis increased $47 million during 2020 primarily due to a decrease in the discount rate, partially offset by changes in demographic assumptions. The decrease in the underfunded status of our health and life insurance benefits is primarily driven by updated per capita cost and trend assumptions due to favorable contract negotiations with insurers. Contributing to the improved funded status is an enhanced gainshare feature on the Medicare Advantage benefit in the amount of $248 million that will offset certain retiree healthcare costs and $180 million is attributable to improved pricing and rebates on prescription drugs. The accumulated benefit obligation for pension benefits, a measure that excludes the effect of prospective salary and wage increases, was $3.2 billion and $3.3 billion at October 31, 2020 and 2019 , respectively. The cumulative postretirement benefit adjustment included in the Consolidated Statement of Stockholders' Deficit is net of deferred taxes related to our postretirement benefit plans of $197 million and $464 million , at October 31, 2020 and 2019 , respectively. Information for pension plans with accumulated benefit obligations in excess of plan assets were as follows: As of October 31, (in millions) 2020 2019 Projected benefit obligations $ 3,234 $ 3,325 Accumulated benefit obligations 3,217 3,307 Fair value of plan assets 1,849 1,991 Generally, the pension plans are non-contributory. Our policy is to fund the pension plans in accordance with applicable U.S. and Canadian government regulations and to make additional contributions from time to time. As of October 31, 2020 , we have met all regulatory funding requirements. In 2020 and 2019 , we contributed $35 million and $140 million , respectively, to our pension plans to meet regulatory funding requirements. During the first quarter of 2019 , we accelerated the payment of a substantial portion of our 2019 minimum required funding. In 2020, we deferred $157 million of previously expected contributions until the first quarter of 2021 under the provisions of the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). We expect to contribute approximately $320 million to our pension plans during 2021 . We primarily fund OPEB obligations, such as retiree medical, in accordance with the 1993 Settlement Agreement, which requires us to fund a portion of the plans' annual service cost to a retiree benefit trust (the "Base Trust"). The 1993 Settlement Agreement resolved a class action lawsuit originally filed in 1992 regarding the restructuring of our then applicable retiree health care and life insurance benefits. In 2020 , we contributed $1 million to our OPEB plans to meet legal funding requirements. We expect to contribute $1 million to our OPEB plans during 2021 . We have certain unfunded pension plans, under which we make payments directly to employees. Benefit payments of $16 million and $17 million for October 31, 2020 and 2019 , respectively, are included within the amount of Benefits paid in the Change in benefit obligation section above, but are not included in the Change in plan assets section, because the payments are made directly by us and not by separate trusts that are used in the funding of our other pension plans. We also have certain OPEB benefits that are paid from Company assets (instead of trust assets). Payments from Company assets, net of participant contributions and subsidy receipts, result in differences between benefits paid as presented under Change in benefit obligation and Change in plan assets of $23 million and $37 million for 2020 and 2019 , respectively. Components of Net Periodic Benefit Expense and Other Amounts Recognized in Other Comprehensive Loss The components of our postretirement benefits expense included in our Consolidated Statements of Operations consist of the following: For the Years Ended October 31, (in millions) 2020 2019 2018 Pension expense $ 63 $ 232 $ 72 Health and life insurance expense 11 31 33 Total postretirement benefits expense $ 74 $ 263 $ 105 Components of Net Periodic Benefit Expense Net periodic benefit expense included in our Consolidated Statements of Operations, and other amounts recognized in our Consolidated Statements of Stockholders' Deficit , for the years ended October 31 is comprised of the following: For the Years Ended October 31, Pension Benefits Health and Life (in millions) 2020 2019 2018 2020 2019 2018 Service cost for benefits earned during the period $ 8 $ 7 $ 7 $ 3 $ 3 $ 4 Interest on obligation 84 121 108 28 49 43 Amortization of cumulative loss (gain) 97 94 106 (1 ) (1 ) 9 Amortization of prior service cost (benefit) 1 — — — — — Settlements 7 143 9 — — — Premiums on pension insurance 11 10 3 — — — Expected return on assets (145 ) (143 ) (161 ) (19 ) (20 ) (23 ) Net periodic benefit expense $ 63 $ 232 $ 72 $ 11 $ 31 $ 33 Other Changes in plan assets and benefit obligations recognized in other comprehensive loss (income) Actuarial net loss (gain) $ 151 $ 316 $ (61 ) $ (445 ) $ (138 ) $ (139 ) Prior service cost — 4 — — — — Amortization of cumulative (loss) gain (97 ) (94 ) (106 ) 1 1 (9 ) Amortization of prior service benefit (cost) (1 ) — — — — — Settlements (7 ) (143 ) (9 ) — — — Total recognized in other comprehensive income $ 46 $ 83 $ (176 ) $ (444 ) $ (137 ) $ (148 ) Total net postretirement benefits (income) expense and other comprehensive loss (income) $ 109 $ 315 $ (104 ) $ (433 ) $ (106 ) $ (115 ) Components of net periodic benefit cost other than service cost are included in Other expense , net in our Consolidated Statements of Operations . For the year ended October 31, 2019, we adopted ASU No. 2017-07 "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." This ASU requires that an employer disaggregate the service cost component from the other components of net periodic benefit cost. As a result, we have reclassified certain net periodic benefit costs from SG&A expenses to Other expense, net in our Consolidated Statements of Operations . The guidance, which required retrospective application, resulted in a reclassification of $94 million for the year ended October 31, 2018. For the years ended October 31, 2020, 2019 and 2018, we purchased group annuity contracts for certain retired pension plan participants resulting in plan remeasurements. The purchase of the group annuity contracts was funded directly by the assets of our pension plans. As a result, in 2020, 2019 and 2018, net actuarial gains of $2 million , net actuarial losses of $11 million and net actuarial losses of $2 million , respectively, were recognized as components of Accumulated other comprehensive loss and non-cash pension settlement accounting expenses of $7 million , $142 million and $9 million , respectively, were recognized in Other expense, net in our Consolidated Statements of Operations . In 2020 and 2019, respectively, in accordance with the intraperiod tax allocation rules, we recorded a net benefit of $75 million and $5 million , respectively, related to domestic continuing operations in Income tax expense in our Consolidated Statements of Operations , and an offsetting reduction in Other comprehensive income due to the remeasurement of certain pension and OPEB plans. The estimated amounts for the defined benefit pension plans and the other postretirement benefit plans that will be amortized from AOCL into net periodic benefit expense over the next fiscal year are as follows: (in millions) Pension Benefits Health and Life Insurance Benefits Amortization of prior service cost $ 1 $ — Amortization of cumulative losses/(gains) 107 (40 ) Cumulative unrecognized actuarial gains and losses for postretirement benefit plans, where substantially all of the plan participants are inactive, are amortized over the average remaining life expectancy of the inactive plan participants. Otherwise, cumulative gains and losses are amortized over the average remaining service period of active employees. Plan amendments unrelated to negotiated labor contracts are amortized over the average remaining service period of active employees or the remaining life expectancy of the inactive participants based upon the nature of the amendment and the participants impacted. Plan amendments arising from negotiated labor contracts are amortized over the length of the contract. Assumptions The weighted average rate assumptions used in determining benefit obligations for the years ended October 31, 2020 and 2019 are: Pension Benefits Health and Life Insurance Benefits 2020 2019 2020 2019 Discount rate used to determine present value of benefit obligation at end of year 2.6 % 3.1 % 2.5 % 3.1 % Expected rate of increase in future compensation levels 3.5 % 3.5 % — — The weighted average rate assumptions used in determining net postretirement benefits expense for 2020 , 2019 , and 2018 were: Pension Benefits Health and Life Insurance Benefits 2020 2019 2018 2020 2019 2018 Discount rate used to determine service cost 3.3 % 4.6 % 3.9 % 3.3 % 4.6 % 3.9 % Discount rate used to determine interest cost 2.6 % 4.0 % 3.0 % 2.7 % 4.1 % 3.1 % Expected long-term rate of return on plan assets 7.2 % 7.4 % 7.2 % 7.3 % 7.5 % 7.5 % Expected rate of increase in future compensation levels 3.5 % 3.5 % 3.5 % — — — The actuarial assumptions used to compute the net postretirement benefits expense (income) are based upon information available as of the beginning of the year, specifically market interest rates, past experience, and our best estimate of future economic conditions. Changes in these assumptions may impact the measurement of future benefit costs and obligations. In computing future costs and obligations, we must make assumptions about such things as employee mortality and turnover, expected salary and wage increases, discount rates, expected returns on plan assets, and expected future cost increases. Three of these items have a significant impact on the level of expense recognized: (i) discount rates, (ii) expected rates of return on plan assets, and (iii) healthcare cost trend rates. We determine the discount rate for our pension and OPEB obligations by matching anticipated future benefit payments for the plans to a high-quality corporate bond yield curve to establish a weighted average discount rate for each plan. We determine our assumption as to expected return on plan assets by evaluating historical performance, investment community forecasts, and current market conditions. We consider the current asset mix as well as our targeted asset mix when establishing the expected return on plan assets. Health care cost trend rates have been established through a review of actual recent cost trends and projected future trends. Our retiree medical and drug cost trend assumptions are our best estimate of expected inflationary increases to healthcare costs. Due to the number of former employees and their beneficiaries included in our retiree population (approximately 25,000 ), the trend assumptions are based upon both our specific trends and nationally expected trends. The weighted average rate of increase in the per capita cost of postretirement health care benefits provided through U.S. plans representing 80% of our other postretirement benefit obligation, is projected to be 3.1% in 2021 and was estimated as 10.1% for 2020 . The 3.1% is assumed to increase to 10.1% in 2022 and then decrease to 5% by the year 2026 and remain at that level thereafter. The OPEB liability estimate is impacted by the level of premiums paid to and gainshare received from insurers, rebates from pharmaceutical companies and government subsidies received on prescription drugs. Future levels of subsidies could also be impacted by the outcome of our Retiree Health Care Litigation, which could be material. The effect of changing the health care cost trend rate by one-percentage point for each future year is as follows: (in millions) One-Percentage One-Percentage Effect on total of service and interest cost components $ 5 $ (4 ) Effect on postretirement benefit obligation 77 (57 ) Plan Assets The accounting guidance on fair value measurements specifies a fair value hierarchy based upon the observability of inputs used in valuation techniques (Level 1, 2 and 3). See Note 14, Fair Value Measurements , for a discussion of the fair value hierarchy. The following describes the methods and significant assumptions used to estimate fair value of the investments: • Cash and short-term investments —Valued at cost plus earnings from investments for the period, which approximates fair market value due to the short-term duration. Cash equivalents are valued at net asset value as provided by the administrator of the fund. • U.S. Government and agency securities —Valued at the closing price reported on the active market on which the security is traded or valued by the trustee at year-end using various pricing services of financial institutions, including Interactive Data Corporation, Standard & Poor's and SIX Telekurs. • Corporate debt securities —Valued by the trustee at year-end using various pricing services of financial institutions, including Interactive Data Corporation, Standard & Poor's and SIX Telekurs. • Common and preferred stock —Valued at the closing price reported on the active market on which the security is traded. • Collective trusts, Partnerships/joint venture interests, Real estate and Hedge funds —Valued at the net asset value provided by the administrator of the fund. The net asset value is based on the value of the underlying assets owned by the fund, minus its liabilities, divided by the number of units outstanding. • Insurance Linked Securities —Valued at the net asset value provided by the administrator of the fund. The net asset value is based on the value of the underlying assets owned by the fund, minus its liabilities, then divided by the number of units outstanding. • Derivatives —Valued monthly for the trustee using various pricing services of financial institutions, including Interactive Data Corporation, Standard & Poor’s and SIX Telekurs. Valued monthly by the trustee using various providers of derivatives pricing, most notably Numerix, Markit and Super Derivatives.

In prior years we used a "look through" approach to individual components of the trust instrument to determine an aggregate fair value. As result of this change, the Collective Trust components are classified as Level 2 in the current period as compared to Level 1 in prior periods.

In prior years we used a "look through" approach to individual components of the trust instrument to determine an aggregate fair value. As result of this change, the Collective Trust components are classified as Level 2 in the current period as compared to Level 1 in prior periods. The investment strategy of the postretirement pension plans (the "Plans") is based on many factors including broad economic factors, historical and prospective information regarding capital market performance, investment strategies available to an asset pool of this size, the current regulatory environment, the Plans’ liabilities and the expected interaction between assets and liabilities. The primary objective of the strategy is to manage assets in such a way that will allow the eventual satisfaction of obligations to the Plans’ participants and beneficiaries. To meet the primary objective the portfolios will be structured to provide liquidity to meet the Plans’ benefit payment obligations and administration expenses, offer a reasonable probability of achieving growth in assets that will assist in closing the Plans’ funding gap and enable the Plans to satisfy their liabilities. Given the relationship between risk and return a moderately aggressive risk profile was implemented. Primary emphasis is to strike a balance between portfolio stability and portfolio appreciation. In line with the Plans' return objectives and risk parameters, target asset allocations are approximately 70% return-seeking assets and 30% liability-hedging assets. The return-seeking assets include long only equities (both active and passive, domestic and international, across the capitalization range) to capture long-term growth opportunities, hedge fund of funds to diversify the equity beta, return seeking credit (including high yield debt, emerging market debt and bank loans) to provide a meaningful level of absolute return and diversify equity beta, global real estate to diversify the equity beta and private equity. The liability-hedging assets are invested in high-quality, investment grade bonds with durations that approximate the durations of the liabilities. The objective of the liability hedging assets is to dampen the Plans’ surplus volatility. All assets are managed by external investment managers. Each investment manager is expected to prudently manage the assets in a manner consistent with the investment objectives, guidelines, and constraints outlined in their Investment Management Agreements and the Investment Policy Statement. Managers are not permitted to invest outside of the asset class mandate (i.e., equity, fixed income, alternatives) or strategy for which they are appointed. Expected Future Benefit Payments The expected future benefit payments for the years ending October 31, 2021 through 2025 and the five years ending October 31, 2030 are estimated as follows: (in millions) Pension Benefit Payments Other Postretirement Benefit Payments (A) 2021 $ 249 $ 31 2022 243 40 2023 236 46 2024 229 46 2025 222 45 2026 through 2030 995 199 ________________________ (A) Payments are net of expected participant contributions and expected federal subsidy receipts. Defined Contribution Plans and Other Contractual Arrangements Our defined contribution plans cover a substantial portion of domestic salaried employees and certain domestic represented employees. The defined contribution plans contain a 401(k) feature and provide most participants with a matching contribution from the Company. In light of recent developments relating to the COVID-19 pandemic, we have implemented cash conservation initiatives including a delay in certain 401(k) company matching contributions until 2021. The matching contribution delay was effective March 1, 2020. Prior to this, the matching contributions for non-represented employees were deposited monthly. Many participants covered by the plans receive annual Company contributions to their retirement accounts based on an age-weighted percentage of the participant's eligible compensation for the calendar year. Defined contribution expense pursuant to these plans was $33 million , $35 million , and $33 million in 2020 , 2019 , and 2018 , respectively. In accordance with the 1993 Settlement Agreement, an independent Retiree Supplemental Benefit Trust (the "Supplemental Trust") was established. The Supplemental Trust, and the benefits it provides to certain retirees pursuant to a certain Retiree Supplemental Benefit Program under the 1993 Settlement Agreement ("Supplemental Benefit Program"), is not part of our consolidated financial statements. Our contingent profit sharing obligations under a certain Supplemental Benefit Trust Profit Sharing Plan ("Supplemental Benefit Trust Profit Sharing Plan") will continue until certain funding targets defined by the 1993 Settlement Agreement are met. As noted within the Profit Sharing Disputes section of Note 15, Commitments and Contingencies , the Company requested the Court reform the 1993 Settlement Agreement to provide clarity regarding certain “Profit Sharing Cessation Date” provisions, which relate to the timing and impact of the cessation of the Company’s Profit Sharing Plan contributions. We are currently unable to determine whether we have achieved the certain funding targets that may result in profit sharing cessation. Upon profit sharing cessation, the company may have ongoing responsibilities related to amortized actuarial and investment losses. In 2020 , we did not record any profit sharing accruals based on the operating performance of the entities that are included in the determination of qualifying profits. In 2019 , we recorded $21 million . For more information on pending arbitration regarding the Supplemental Benefit Trust Profit Sharing Plan, see Note 15, Commitments and Contingencies .

Income Taxes

Income Taxes	12 Months Ended
	Oct. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On March 27, 2020, the CARES Act was enacted in response to the COVID-19 pandemic. The CARES Act contains numerous income tax provisions, such as relaxing the limitations on the deductibility of interest and the carryback of net operating losses for specific periods. We have performed an analysis of these provisions and due to the unavailability of excess taxable income in the current or carry back periods, and the application of a valuation allowance to deferred tax assets, the Company's effective income tax rate and its tax provision are currently unaffected by the provisions of the CARES Act. Additionally, the CARES Act provides for refundable employee retention credits and the deferral of the employer-paid portion of social security taxes. As of October 31, 2020, we elected to defer the employer-paid portion of social security taxes for the remainder of 2020, to be repaid equally in December 2021 and December 2022. The total employer-paid portion of social security taxes deferred as of October 31, 2020 is $16 million. We intend to claim the refundable employee retention tax credits provided under the CARES Act, which can be used to offset payroll tax liabilities. We estimate the potential benefits that the employee retention credits can provide to be approximately $3.6 million. The following table presents the domestic and foreign components of Income (loss) before income taxes in our Consolidated Statements of Operations : For the Years Ended October 31, (in millions) 2020 2019 2018 Domestic $ (476 ) $ 220 $ 246 Foreign 88 42 174 Income (loss) before income taxes $ (388 ) $ 262 $ 420 The following table presents the components of Income tax (expense) benefit in our Consolidated Statements of Operations : For the Years Ended October 31, (in millions) 2020 2019 2018 Current: Federal $ (1 ) $ 2 $ — State and local (1 ) 3 1 Foreign 23 46 47 Total current expense $ 21 $ 51 $ 48 Deferred: Federal $ (60 ) $ (1 ) $ (2 ) State and local (15 ) (5 ) 1 Foreign (5 ) (26 ) 5 Total deferred (benefit) expense $ (80 ) $ (32 ) $ 4 Total income tax (benefit) expense $ (59 ) $ 19 $ 52 The following table presents a reconciliation of statutory federal income tax expense (benefit) recorded in Income tax (expense) benefit in our Consolidated Statements of Operations : For the Years Ended October 31, (in millions) 2020 2019 2018 Federal income tax (benefit) expense (A) $ (81 ) $ 55 $ 98 State income taxes, net of federal benefit 2 2 3 Credits and incentives 11 16 50 Adjustments to valuation allowances 110 (94 ) (1,120 ) Foreign operations (4 ) 1 2 Adjustments to uncertain tax positions (2 ) 2 1 Intraperiod tax allocation offset to equity components (75 ) (5 ) — Non-controlling interest adjustment (4 ) (5 ) (6 ) Foreign inclusions (7 ) 34 — Tax law change (20 ) — — Tax act mandatory repatriation — — 34 Tax act US deferred remeasurement — — 983 Other 11 13 7 Recorded income tax (benefit) expense $ (59 ) $ 19 $ 52 _________________________ (A) Federal income tax expense was taxed at a rate of 21% for the years ended 2020 and 2019 and 23% for the year ended 2018 . The tax effect of pretax income or loss from continuing operations generally should be determined by a computation that does not consider the tax effects of items that are not included in continuing operations. An exception to that incremental approach is applied when there is a loss from continuing operations and income in another category of earnings (for example, discontinued operations, other comprehensive income, additional paid in capital, etc.). In that situation, a tax provision is first allocated to the other categories of earnings. A related tax benefit is then recorded in continuing operations. This exception to the general rule applies even when a valuation allowance is in place at the beginning and end of the year. While intraperiod tax allocations do not change the overall tax provision, it may result in a gross-up of the individual components, thereby changing the amount of tax provision included in each category of income. During 2020 and 2019 , we recorded $75 million and $5 million , respectively, for intraperiod allocation benefits in domestic continuing operations associated with certain postretirement plan remeasurement gains. Not including the effect of the federal income tax rate change, as a result of the Tax Act, which reduces the statutory corporate income tax rate from 35% to 21%, effective January 1, 2018, we recognized an income tax expense of $110 million , and an income tax benefit of $94 million and $137 million , for the change in the valuation allowance for the years ended October 31, 2020 , 2019 and 2018 , respectively. At October 31, 2020 , undistributed earnings of foreign subsidiaries were $379 million . Income taxes have not been provided on foreign undistributed earnings, whether previously taxed or not, because they are either considered to be permanently invested in foreign subsidiaries or are expected to be repatriated without significant incremental U.S. federal, state or foreign withholding taxes. It is impracticable to determine the exact amount of unrecognized deferred tax liabilities. The following table presents the components of the deferred tax asset (liability): As of October 31, (in millions) 2020 2019 Deferred tax assets attributable to: Employee benefits liabilities $ 501 $ 578 Net operating loss ("NOL") carryforwards 801 782 Product liability and warranty accruals 151 165 Research and development 179 144 Tax credit carryforwards 183 196 Other 395 279 Gross deferred tax assets 2,210 2,144 Less: Valuation allowances 2,020 2,011 Net deferred tax assets $ 190 $ 133 Deferred tax liabilities attributable to: Other $ (73 ) $ (18 ) Total deferred tax liabilities $ (73 ) $ (18 ) At October 31, 2020 , deferred tax assets attributable to NOL carryforwards include $495 million attributable to U.S. federal NOL carryforwards, $165 million attributable to state NOL carryforwards, and $141 million attributable to foreign NOL carryforwards. If not used to reduce future taxable income, U.S. federal NOLs are scheduled to expire beginning in 2032. State NOLs can be carried forward for initial periods of 5 to 20 years, and are scheduled to expire in 2021 to 2040. Approximately one third of our foreign net operating losses will expire beginning in 2027, and another approximate one third of our foreign net operating losses will expire beginning in 2033, while the remaining one third has no expiration date. The majority of our tax credits can be carried forward for initial periods of 20 years and are scheduled to expire between 2021 and 2040. A valuation allowance is required to be established or maintained when, based on currently available information, it is more likely than not that all or a portion of a deferred tax asset will not be realized. The guidance on accounting for income taxes provides important factors in determining whether a deferred tax asset will be realized, including whether there has been sufficient taxable income in recent years and whether sufficient income can reasonably be expected in future years in order to utilize the deferred tax asset. For the year ended October 31, 2020 , we have evaluated the need to maintain a valuation allowance for deferred tax assets based on our assessment of whether it is more likely than not that deferred tax benefits will be realized through the generation of future taxable income. Appropriate consideration is given to all available evidence, both positive and negative, in assessing the need for a valuation allowance. We incurred domestic losses from continuing operations for the year ended October 31, 2020 and domestic income for the years ended October 31, 2019 and 2018 . The positive evidence of domestic income from the years ended October 31, 2019 and 2018 does not outweigh the negative evidence of cumulative losses from prior years. The qualitative and quantitative analysis of current and expected domestic earnings, industry volumes, tax planning strategies, and general business risks resulted in a more likely than not conclusion of not being able to realize a significant portion of our deferred tax assets as of October 31, 2020 . We continue to maintain a valuation allowances on the majority of our U.S. deferred tax assets as well as certain foreign deferred tax assets that we believe, on a more-likely-than-not basis, will not be realized based on current forecasted results. For all remaining deferred tax assets, while we believe that it is more likely than not that they will be realized, we believe that it is reasonably possible that additional deferred tax asset valuation allowances could be required in the next twelve months. The total deferred tax asset valuation allowances were $2.0 billion at both October 31, 2020 and 2019 . In the event we released all of our valuation allowances, almost all would impact income taxes as a benefit in our Consolidated Statements of Operations. We recognize the tax benefit from an uncertain tax position only if it is 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. As of October 31, 2020 , the amount of liability for uncertain tax positions was $20 million . The liability at October 31, 2020 has a recorded offsetting tax benefit associated with various issues that total $10 million . If the unrecognized tax benefits are recognized, all would impact our effective tax rate, except for positions for which we maintain a full valuation allowance against certain deferred tax assets. In this case, the effect may be in the form of an increase in the deferred tax asset related to our net operating loss carryforward, which would be offset by a full valuation allowance. Changes in the liability for uncertain tax positions are summarized as follows: For the years ended October 31, (in millions) 2020 2019 Liability for uncertain tax positions at November 1 $ 21 $ 27 Additions as a result of positions taken in prior periods 1 3 Decrease as a result of positions taken in prior periods (2 ) (2 ) Settlements — (7 ) Liability for uncertain tax positions at October 31 $ 20 $ 21 We recognize interest and penalties related to uncertain tax positions as part of Income tax expense . Total interest and penalties related to our uncertain tax positions resulted in income tax benefit of $1 million , income tax expense of less than $1 million , and income tax benefit of $1 million for the years ended October 31, 2020 , 2019 , and 2018 , respectively. The total interest and penalties accrued were $3 million and $4 million for the years ended October 31, 2020 and 2019 , respectively. We have open tax years back to 2001 with various significant taxing jurisdictions including the U.S., Canada, Mexico, and Brazil. In connection with the examination of tax returns, contingencies may arise that generally result from differing interpretations of applicable tax laws and regulations as they relate to the amount, timing, or inclusion of revenues or expenses in taxable income, or the sustainability of tax credits to reduce income taxes payable. In fiscal 2018, we received a favorable ruling from the Brazilian court in connection with certain Brazil indirect federal taxes (PIS and COFINS) credits. During the fourth quarter of 2020, we estimated that it was probable to receive a benefit of $7 million, net of reserves, (translated into US dollars as of October 31, 2020) associated with tax years 2002 to 2010. We recorded $3 million of a benefit in Sales of manufactured products, net and $4 million of interest income in Interest expense (income) in our Consolidated Statements of Operations in our Global Operations segment. Timing on realization of these recoveries is dependent upon the timing of administrative approvals and generation of federal tax liabilities eligible for offset or sale. The Brazilian IRS has filed a Motion of Clarification on this matter with the Brazilian Supreme Court, which is awaiting decision as of the time of this disclosure. Additional contingencies that would result in tax recoveries may be resolved in future periods which could be material. We believe we have sufficient accruals for our contingent tax liabilities. Annual tax provisions include amounts considered sufficient to pay assessments that may result from examinations of prior year tax returns, although actual results may differ. While it is probable that the liability for unrecognized tax benefits may increase or decrease during the next twelve months, we do not expect any such change would have a material effect on our financial condition, results of operations, or cash flows.

Fair Value Disclosures [Abstract]
Fair value measurements	Fair Value Measurements For assets and liabilities measured at fair value on a recurring and nonrecurring basis, a three-level hierarchy of measurements based upon observable and unobservable inputs is used to arrive at fair value. Observable inputs are developed based on market data obtained from independent sources, while unobservable inputs reflect our assumptions about valuation based on the best information available in the circumstances. Depending on the inputs, we classify each fair value measurement as follows: • Level 1—based upon quoted prices for identical instruments in active markets, • Level 2—based upon quoted prices for similar instruments, prices for identical or similar instruments in markets that are not active, or model-derived valuations, all of whose significant inputs are observable, and • Level 3—based upon one or more significant unobservable inputs. The following section describes key inputs and assumptions in our valuation methodologies: Cash Equivalents and Restricted Cash Equivalents —Cash equivalents are highly liquid investments with an original maturity of 90 days or less which may include U.S. government and federal agency securities, commercial paper, and other highly liquid investments. The carrying amounts of cash and cash equivalents and restricted cash approximate fair value because of the short-term maturity and highly liquid nature of these instruments. Derivative Assets and Liabilities —We measure the fair value of derivatives assuming that the unit of account is an individual derivative transaction and that each derivative could be sold or transferred on a stand-alone basis. We classify within Level 2 our derivatives that are traded over-the-counter and valued using internal models based on observable market inputs. Guarantees —We provide certain guarantees of payments and residual values, to which losses are generally capped, to specific counterparties. The fair value of these guarantees includes a contingent component and a non-contingent component that are based upon internally developed models using unobservable inputs. We classify these liabilities within Level 3. For more information regarding guarantees, see Note 15, Commitments and Contingencies. Impaired Finance Receivables and Impaired Assets Under Operating Leases —Fair values of the underlying collateral are determined by current and forecasted sales prices, aging of and demand for used trucks, and the mix of sales through various market channels. For more information regarding impaired finance receivables, see Note 5, Allowance for Doubtful Accounts, and for more information regarding impaired assets under operating leases, see Note 3, Restructuring, Impairments and Divestitures. Impaired Property, Plant and Equipment —We generally measure the fair value by discounting future cash flows expected to be received from the operation of, or disposition of, the asset or asset group that has been determined to be impaired. When appropriate, we utilize alternative methods for the measurement of fair value such as market and cost approaches. For more information regarding the impairment of property, plant and equipment, see Note 3, Restructuring, Impairments and Divestitures. The following table presents the financial instruments measured at fair value on a recurring basis: As of October 31, 2020 As of October 31, 2019 (in millions) Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Derivative financial instruments: Commodity forward contracts (A) $ — $ 4 $ — $ 4 $ — $ — $ — $ — Foreign currency contracts (A) — 5 — 5 — 1 — 1 Total assets $ — $ 9 $ — $ 9 $ — $ 1 $ — $ 1 Liabilities Derivative financial instruments: Commodity forward contracts (B) $ — $ 2 $ — $ 2 $ — $ 1 $ — $ 1 Foreign currency contracts (B) — 3 — 3 — 2 — 2 Guarantees — — 29 29 — — 27 27 Total liabilities $ — $ 5 $ 29 $ 34 $ — $ 3 $ 27 $ 30 _________________________ (A) The asset values of commodity forward contracts and foreign currency contracts are included in Other current assets and Other noncurrent assets in the accompanying Consolidated Balance Sheets . (B) The liability values of commodity forward contracts and foreign currency contracts are included in Other current liabilities and Other noncurrent liabilities in the accompanying Consolidated Balance Sheets. The following table presents the changes for those financial instruments classified within Level 3 of the valuation hierarchy: (in millions) October 31, 2020 October 31, 2019 Guarantees at beginning of period $ (27 ) $ (24 ) Net issuances (8 ) (6 ) Settlements 6 3 Guarantees at end of period $ (29 ) $ (27 ) There were no transfers of level 3 financial instruments. The following table presents the financial instruments measured at fair value on a nonrecurring basis: (in millions) October 31, 2020 October 31, 2019 Level 2 financial instruments Impaired finance receivables (A) $ 31 $ 23 Specific loss reserve (12 ) (11 ) Fair value $ 19 $ 12 _________________________ (A) Certain impaired finance receivables are measured at fair value on a nonrecurring basis. An impairment charge is recorded for the amount by which the carrying value of the receivables exceeds the fair value of the underlying collateral, net of remarketing costs. Fair values of the underlying collateral are determined by reference to dealer vehicle value publications adjusted for certain market factors. In addition to the methods and assumptions we use for the financial instruments recorded at fair value as discussed above, we use the following methods and assumptions to estimate the fair value for our other financial instruments that are not marked to market on a recurring basis. The carrying amounts of Cash and cash equivalents , Restricted cash , and Accounts payable approximate fair values because of the short-term maturity and highly liquid nature of these instruments. Finance receivables generally consist of retail and wholesale accounts and notes. The carrying amounts of Trade and other receivables and retail and wholesale accounts approximate fair values as a result of the short-term nature of the receivables. The carrying amounts of wholesale notes approximate fair values as a result of the short-term nature of the wholesale notes and their variable interest rate terms. Due to the nature of the aforementioned financial instruments, they have been excluded from the fair value amounts presented in the table below. The fair values of our retail notes are estimated by discounting expected cash flows at current market rates. The fair values of our retail notes are classified as Level 3 financial instruments. The fair values of our debt instruments classified as Level 1 were determined using quoted market prices. The 4.75% Tax-Exempt Bonds, due 2040, are traded, but the trading market is illiquid, and as a result, the Loan Agreement underlying the Tax-Exempt Bonds is classified as Level 2. Trading in our 6.625% Senior Notes and our 9.5% Senior Secured Notes is limited to qualified institutional buyers; therefore, the notes are classified as Level 2. The fair values of our Level 3 debt instruments are generally determined using internally developed valuation techniques such as discounted cash flow modeling. Inputs such as discount rates and credit spreads reflect our estimates of assumptions that market participants would use in pricing the instrument and may be unobservable. The following tables present the carrying values and estimated fair values of financial instruments: As of October 31, 2020 Estimated Fair Value Carrying Value (in millions) Level 1 Level 2 Level 3 Total Assets Retail notes $ — $ — $ 223 $ 223 $ 222 Liabilities Debt: Manufacturing operations Senior Secured Term Loan Credit Agreement, due 2025 — — 1,538 1,538 1,543 9.5% Senior Secured Notes, due 2025 — 665 — 665 589 6.625% Senior Notes, due 2026 — 1,137 — 1,137 1,087 Loan Agreement related to 4.75% Tax-Exempt Bonds, due 2040 — 227 — 227 223 Financed lease obligations — — 46 46 45 Other (A) — — 7 7 7 Financial Services operations Asset-backed debt issued by consolidated SPEs, due serially through 2022 — — 726 726 724 Bank credit facilities, due dates from 2021 through 2025 — — 914 914 940 Borrowings secured by operating and finance leases, due serially through 2024 — — 171 171 170 As of October 31, 2019 Estimated Fair Value Carrying Value (in millions) Level 1 Level 2 Level 3 Total Assets Retail notes $ — $ — $ 205 $ 205 $ 208 Liabilities Debt: Manufacturing operations Senior Secured Term Loan Credit Agreement, due 2025 — — 1,552 1,552 1,556 6.625% Senior Notes, due 2026 — 1,122 — 1,122 1,085 Loan Agreement related to 6.75% Tax-Exempt Bonds, due 2040 — 234 — 234 220 Financed lease obligations — — 60 60 60 Other (A) — — 9 9 9 Financial Services operations Asset-backed debt issued by consolidated SPEs, due serially through 2022 — — 995 995 991 Bank credit facilities, due dates from 2021 through 2025 — — 1,038 1,038 1,059 Commercial paper, at variable rates, program matures in 2022 84 — — 84 84 Borrowings secured by operating and finance leases, due serially through 2024 — — 122 122 122 _________________________ (A) Excludes non-financial instrument debt of $2 million as of both October 31, 2020 and 2019 .

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Guarantees We occasionally provide guarantees that could obligate us to make future payments if the primary entity fails to perform under its contractual obligations. We have recognized liabilities for some of these guarantees in our Consolidated Balance Sheets as they meet the recognition and measurement provisions of GAAP. In addition to the liabilities that have been recognized, we are contingently liable for other potential losses under various guarantees. We do not believe that claims that may be made under such guarantees would have a material effect on our financial condition, results of operations, or cash flows. Under the terms of the Navistar Capital Operating Agreement, BMO is our third-party preferred source of retail and lease customer financing for equipment offered by us and our dealers in the U.S. The Navistar Capital Operating Agreement, as amended, contains a loss sharing arrangement under which we generally reimburse BMO for excess credit losses as defined in the arrangement. Our exposure to loss is mitigated because contracts under the Navistar Capital Operating Agreement are secured by the financed equipment. There were $1.5 billion and $1.6 billion of outstanding loan principal and operating lease payments receivable at October 31, 2020 and 2019 , respectively, financed through the Navistar Capital Operating Agreement and subject to the loss sharing arrangements in the U.S. The related financed values of these outstanding contracts were $2.5 billion and $2.7 billion at October 31, 2020 and 2019 , respectively. We have recognized a guarantee liability for our portion of estimated Navistar Capital credit losses. Generally, we do not carry the contracts under the Navistar Capital Operating Agreement on our Consolidated Balance Sheets . In response to the COVID-19 pandemic, BMO has restructured certain loans that are subject to the loss sharing arrangement. We have increased our estimated guarantee liability for potential COVID-19 related credit losses by an amount which was not material to our consolidated financial statements. For certain third-party financed contracts, we have recognized equipment leased to others of $39 million and $51 million and financed lease and other obligations of $49 million and $60 million , in our Consolidated Balance Sheets as of October 31, 2020 and 2019 , respectively. We also have issued a limited number of residual value guarantees, for which losses are generally capped. If control has not transferred, we generally account for these arrangements as operating leases and revenue is recognized on a straight-line basis over the term of the lease. If control has transferred, revenue is recognized upon sale and the amounts of the guarantees are estimated and recorded. Our guarantees are contingent upon the fair value of the leased assets at the end of the lease term. We have recognized liabilities for some of these guarantees in our Consolidated Balance Sheets as they meet recognition and measurement provisions. In addition to the liabilities that have been recognized, we are contingently liable for other potential losses under various guarantees that are not recognized in our Consolidated Balance Sheets . We do not believe claims that may be made under such guarantees would have a material effect on our financial condition, results of operations, or cash flows. We obtain certain stand-by letters of credit and surety bonds from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance-related requirements. As of October 31, 2020 , the amount of stand-by letters of credit and surety bonds issued was $85 million . In addition, as of October 31, 2020 , we had $140 million of outstanding purchase commitments and contracts with $20 million of cancellation fees with expiration dates through 2028. In the ordinary course of business, we also provide routine indemnifications and other guarantees, the terms of which range in duration and often are not explicitly defined. We do not believe these will result in claims that would have a material impact on our financial condition, results of operations, or cash flows. Environmental Liabilities We have been named a potentially responsible party ("PRP"), in conjunction with other parties, in a number of cases arising under an environmental protection law, the Comprehensive Environmental Response, Compensation, and Liability Act, popularly known as the "Superfund" law. These cases involve sites that allegedly received wastes from current or former Company locations. Based on information available to us which, in most cases, consists of data related to quantities and characteristics of material generated at current or former Company locations, material allegedly shipped by us to these disposal sites, as well as cost estimates from PRPs and/or federal or state regulatory agencies for the cleanup of these sites, a reasonable estimate is calculated of our share of the probable costs, if any, and accruals are recorded in our consolidated financial statements. These accruals are generally recognized no later than upon completion of the remedial feasibility study and are not discounted to their present value. We review all accruals on a regular basis and believe that, based on these calculations, our share of the potential additional costs for the cleanup of each site will not have a material effect on our financial condition, results of operations, or cash flows. In addition, other sites formerly owned by us or where we are currently operating have been identified as having soil and groundwater contamination. While investigations and cleanup activities continue at these sites, we believe that we have appropriate accruals to cover costs to complete the cleanup of all sites. We have accrued $18 million for these and other environmental matters, which are included within Other current liabilities and Other noncurrent liabilities , as of October 31, 2020 . The majority of these accrued liabilities are expected to be paid subsequent to 2021 . Along with other vehicle manufacturers, we have been subject to a number of asbestos-related claims. In general, these claims relate to illnesses alleged to have resulted from asbestos exposure from component parts found in older vehicles, although some cases relate to the alleged presence of asbestos in our facilities. In these claims, we are generally not the sole defendant, and the claims name as defendants numerous manufacturers and suppliers of a wide variety of products allegedly containing asbestos. We have strongly disputed these claims, and it has been our policy to defend against them vigorously. Historically, the actual damages paid out to claimants have not been material in any year to our financial condition, results of operations, or cash flows. It is possible that the number of these asbestos-related claims, and the costs for resolving them, could become significant in the future. Legal Proceedings Overview We are subject to various claims arising in the ordinary course of business and are party to various legal proceedings that constitute ordinary, routine litigation incidental to our business. The majority of these claims and proceedings relate to commercial, product liability, and warranty matters. In addition, from time to time we are subject to various claims and legal proceedings related to employee compensation, benefits, and benefits administration including, but not limited to, compliance with the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and Department of Labor requirements. In our opinion, apart from the actions set forth below, the disposition of these proceedings and claims, after taking into account recorded accruals and the availability and limits of our insurance coverage, will not have a material adverse effect on our business or our financial condition, results of operations, or cash flows. Profit Sharing Disputes Pursuant to the 1993 Settlement Agreement, the program administrator and named fiduciary of the Supplemental Benefit Program is the Committee, composed of individuals not appointed by NI or NIC. In August 2013, the Committee filed a motion for leave to (a) amend its February 2013 complaint (which sought injunctive relief for the Company to provide certain information to which the Committee was allegedly entitled under the Profit Sharing Plan) and (b) file a proposed amended complaint (the "Profit Sharing Complaint") in the U.S. District Court for the Southern District of Ohio (the "Court"). Leave to file the Profit Sharing Complaint was granted by the Court in October 2013. In its Profit Sharing Complaint, the Committee alleged that the Company breached the 1993 Settlement Agreement and violated ERISA by failing to properly calculate profit sharing contributions due under the Profit Sharing Plan and sought damages in excess of $50 million , injunctive relief and reimbursement of attorneys' fees and costs. Following the resolution of a procedural dispute by the U.S. Court of Appeals for the 6th Circuit, in May 2015 the Court ordered that the claims in the Profit Sharing Complaint be arbitrated pursuant to the dispute resolution procedures in the Profit Sharing Plan. The Company and the Committee selected an arbitrator and the arbitration discovery process commenced. On June 29, 2017, the arbitrator ruled, among other things, that the arbitration will include Profit Sharing Plan calculations for the years ending October 31, 2001 through October 31, 2014. The Company disputes the arbitrator's June 29, 2017 ruling. On February 17, 2020, the Committee filed its written submission with the arbitrator and requested a damages award of $588 million composed of $252 million in profit sharing contributions that the Committee asserts are due under the Profit Sharing Plan and $336 million of lost earnings that the Committee asserts the Supplemental Trust would have earned had those profit sharing contributions been made and invested. The Company’s written submission to the arbitrator was filed March 16, 2020 and the Committee's reply was filed April 7, 2020. On June 5, 2020 the parties and the arbitrator agreed the only years at issue for the arbitration are the years ending October 31, 2006 and 2008 through 2011. On September 15, 2020, the arbitrator issued a "Tentative Award" concluding the Company made certain incorrect Profit Sharing Plan calculations, rejecting the Committee's claim for lost earnings, and awarding the maximum rate of interest on the Tentative Award as allowed by Illinois law. Under Illinois statute 815 ILCS 2O5/2, the maximum prejudgment interest rate is 5% per year. On December 2, 2020, after additional briefing and closing arguments, the arbitrator informed the parties that the next arbitrator ruling issued would not include a computation amount and would not materially change from the Tentative Award. The Company disputes the Tentative Award. On December 11, 2020, the arbitrator issued a “Semi-Final Award”, concluding again, that the Company made certain incorrect Profit Sharing Plan calculations, rejecting again the Committee’s claim for lost earnings, and awarding the maximum rate of interest on the Semi-Final Award as allowed by Illinois law. The Company disputes the Semi-Final Award. The arbitrator ordered the parties to meet and confer and jointly recalculate Profit Sharing Plan contributions for years ending October 31, 2006 and 2008 through 2011 based on the Semi-Final Award. If the parties do not agree on the final contribution amounts, the parties are required to submit their calculations by February 1, 2021, and the arbitrator will perform the final calculations to include in a final award. By letter dated February 14, 2019, the Committee indicated the Profit Sharing Plan calculation for the plan year ending October 31, 2018 reflects numerous positions that have caused the Committee to dispute the Profit Sharing Plan calculations in the past, and on that basis the Committee disagrees with the 2018 calculation. The Committee also requested information about the 2018 calculation. On March 12, 2019, the Committee filed a motion to enforce the 1993 Settlement Agreement for the Company’s failure to respond to the Committee’s February 14, 2019 information requests. On May 15, 2019, the Company responded to the information requests. The motion to enforce is still pending with the Court, but on October 30, 2019, the Company and the Committee met with the Court regarding the motion to enforce, and agreed on a plan for the Company to respond to the Committee’s information and document requests related to the 2018 calculation (which also relates to the information requested for the Profit Sharing Plan calculations for the years ending October 31, 2001 through October 31, 2014). Furthermore, the Committee informed the Company, by letter dated January 19, 2020, that it disputes the Company's Profit Sharing Plan calculations for the years ending October 31, 2015 through October 31, 2019. For Profit Sharing Plan calculations for the years ending October 31, 2015 through 2020, the Company and the Committee have agreed to confer regarding the impact of the arbitrator's final award, when issued, as referenced above. As noted under “Retiree Health Care Litigation” below, on August 14, 2018, the Company filed a motion to schedule a status hearing, in which the Company requested an in-person hearing to discuss the possibility of a global resolution of various disputes under the 1993 Settlement Agreement, including the pending Profit Sharing Complaint. As a result, in-person hearings, an in-chambers conference and several telephone conferences were held with the Court and on April 17, 2020, the Company filed a motion to reform the 1993 Settlement Agreement. A hearing on the motion to reform the 1993 Settlement Agreement was held on June 1, 2020. On September 9, 2020, the Committee filed a motion to dismiss the Company's filed statement regarding “Phase 2” of the hearings, in which the Company requested the Court to reform the 1993 Settlement Agreement to provide clarity regarding certain “Profit Sharing Cessation Date” provisions, which relate to the timing and impact of the cessation of the Company’s Profit Sharing Plan contributions. The Committee argues the Court lacks jurisdiction because there are no pending disputes regarding the Profit Sharing Cessation Date provisions, and any future disputes fall under an arbitration provision in the 1993 Settlement Agreement. On September 30, 2020, the Company filed its opposition to the Committee’s motion to dismiss, and on October 14, 2020 the Committee filed its reply. The Company’s motion to reform the 1993 Settlement Agreement, including the Committee’s motion to dismiss regarding Phase 2 of the hearings, is pending with the Court. Additional hearings and/or conferences may be scheduled in the future. In addition, various local bargaining units of the UAW have filed separate grievances pursuant to the profit sharing plans under various collective bargaining agreements in effect between the Company and the UAW that may have similar legal and factual issues as the Profit Sharing Complaint. Based on our assessment of the facts underlying the claims in the above actions, we recorded a charge in the Company's fiscal quarter ending in October 31, 2020 in the amount of $289 million for the estimated liability, including $85 million for estimated interest, related to the arbitrator's Semi-Final Award noted above. The award is not final and is subject to change based upon final calculations and such change could be material. The charge is included in SG&A expenses in our Consolidated Statement of Operations , and includes an estimated liability for all years ending on or before October 31, 2020. Other than the aforementioned, we are unable to provide meaningful quantification of how the final resolution of these claims may impact our future consolidated financial condition, results of operations, or cash flows. Retiree Health Care Litigation On October 21, 2016, a lawsuit was filed with the Court by two individual members of the Committee (the “Committee Members”) who are retirees and participants in the Navistar, Inc. Health Benefit and Life Insurance Plan (the “Plan”) created pursuant to the 1993 Settlement Agreement. The Committee Members’ complaint (the “Committee Members’ Complaint”) was filed against NIC, NI, NFC and certain other former or current affiliates, all of which are parties or employers as defined in the 1993 Settlement Agreement. The Committee Members alleged, among other things, that the Company violated the terms of the Plan, breached a fiduciary duty under ERISA, and engaged in ERISA-prohibited transactions by improperly using the Plan’s assets (a portion of certain Medicare Part D subsidies and a portion of certain Medicare Part D coverage-gap discounts (collectively, the "Subsidies"), in each case that were received by Navistar, Inc. Retiree Health Benefit Trust created pursuant to the 1993 Settlement Agreement (the "Base Trust")) for the Company’s benefit. The Committee Members requested that the Court order the defendants to restore all losses to the Base Trust, including approximately $26 million , which the Committee Members allege is the Plan participants’ “fair share” of the Subsidies that were allegedly misappropriated by the defendants from January 2012 through April 2015. The Committee Members also requested that the Court enjoin the defendants from alleged future violations of the Plan and ERISA with respect to treatment of the Subsidies, order the defendants to remedy all alleged ERISA-prohibited transactions and pay the Committee Members’ attorneys’ fees and costs. The Court bifurcated the case and in September 2018 the Court conducted a trial on the issue of whether the Committee Members’ Complaint is barred by the applicable statute of limitations. On November 20, 2018, the Committee Members filed a motion for sanctions, alleging various discovery and trial misconduct by the defendants, and requested that the Court enter judgment in favor of the Committee Members with respect to the statute of limitations issue and award attorneys’ fees to the Committee Members. On March 26, 2019, the Court granted the Committee Members’ motion for sanctions and subsequently extended the statute of limitations discovery period to October 7, 2019. Briefing on the statute of limitations issue was completed in January 2020. The Court also ordered the Company to pay certain of the Committee Members' legal and other costs to file the motion for sanctions and to conduct additional discovery related to the statute of limitations issue. On August 14, 2018, under the original Shy et. al. v. Navistar International Corporation, Civil Action No. 3:92-CV-333 (S.D. Ohio 1992), the Company filed a motion to schedule a status hearing to request an in-person hearing to discuss the possibility of a global resolution of various disputes under the 1993 Settlement Agreement, including but not limited to resolving the pending Profit Sharing Complaint and Committee Members’ Complaint described above. As a result, in-person hearings, an in-chambers conference and several telephone conferences were held with the Court and on April 17, 2020, the Company filed a motion to reform the 1993 Settlement Agreement. A hearing on the motion to reform the 1993 Settlement Agreement was held on June 1, 2020. Additional hearings and/or conferences may be scheduled in the future. Based on our assessment of the facts underlying the claims in the above actions, we are unable to provide meaningful quantification of how the final resolution of these claims may impact our future consolidated financial condition, results of operations, or cash flows. However, future levels of the Subsidies could be impacted by the outcome of the above actions, which could be material to the Company's OPEB obligation. For more information see Note 12, Postretirement Benefits . FATMA Notice International Indústria Automotiva da América do Sul Ltda. ("IIAA"), formerly known as Maxion International Motores S/A ("Maxion"), now a wholly owned subsidiary of the Company, received a notice (the “FATMA Notice”) in July 2010 from the State of Santa Catarina Environmental Protection Agency ("FATMA") in Brazil. The FATMA Notice alleged that Maxion sent waste to a facility owned and operated by a company known as Natureza (the “Natureza Facility”) and that soil and groundwater contamination had occurred at the Natureza Facility. The FATMA Notice asserted liability against Maxion and assessed an initial penalty in the amount of R $2 million (the equivalent of approximately less than US $1 million at October 31, 2020 ), which is not final or due until all administrative appeals are exhausted. Maxion was one of numerous companies that received similar notices. IIAA filed an administrative defense in August 2010 and has not yet received a decision following that filing. In addition to the matter described above, there is a suit pending in the federal court of Brazil in which the federal district attorney has sued (a) FATMA, for claims related to FATMA’s actions in connection with licensing and inspection procedures related to the Natureza Facility, and (b) Selamix, as the current owner of the Natureza Facility. In this federal suit, Selamix was found liable for the contamination at the Natureza Facility due to it being the successor owner of the facility. However, the federal court’s decision does not prohibit Selamix from seeking to recover its damages from third parties that contributed to the contamination at the Natureza Facility. In January 2018, the district attorney of the State of Santa Catarina (the "SC District Attorney"), local and state authorities, Selamix, IIAA and the 14 other companies (together, the "Companies") that are alleged to have significantly contributed to the contamination met to discuss the matter. In March 2018, Selamix informed the SC District Attorney that it would voluntarily conduct a preliminary environmental study at the Natureza Facility in an attempt to determine and allocate the liability for the contamination pursuant to an agreement with the Companies after the study is completed. The SC District Attorney agreed to suspend further inquiry into the matter until Selamix’s study had been completed. In June 2018, Selamix presented its Environmental Preliminary Assessment Report to the SC District Attorney and the Companies alleged to have contributed to the contamination. Selamix also presented commercial proposals from two additional companies specializing in environmental studies to perform the next steps of the technical work. The SC District Attorney then requested a third commercial proposal. One of the commercial proposals included an Environmental Preliminary Assessment Report ("Phase 1 Study") and indicated that a Phase 2 assessment should be performed. In July 2019, the SC District Attorney requested that each of the Companies (including IIAA) inform the SC District Attorney of whether they intended to contribute to the costs of the portion of the Phase 2 assessment related to geophysical investigations to identify buried drums at the Natureza Facility. The request did not include any information related to the potential range of the associated costs or indicate whether contributions for the cost of the other portions of the Phase 2 assessment would be sought from the Companies (including IIAA). IIAA responded to the request indicating that it would not contribute to the cost of the Phase 2 assessment related to geophysical investigations and requested a meeting with the SC District Attorney to discuss the next steps in the process. In late February 2020, IIAA became aware that the SC District Attorney filed an action in the civil court of Santa Catarina against nine of the Companies (including IIAA), Selamix, and the Municipality of Schroeder (where the Natureza Facility is located) requesting that the defendants in the action bear all of the potential costs of the investigation needed to determine the parties responsible for the contamination and manage the remediation of the contamination at the Natureza Facility and that the defendants place funds in escrow to cover such costs. Prior to ruling on these issues, the court has indicated that it will schedule a hearing to allow the defendants to set forth their defenses. In May 2020, the Municipality of Schroeder presented its defenses to the court and alleged that (i) it was not liable for contamination after FATMA, as a state agency, became responsible for the environmental licensing of Natureza, (ii) Selamix should be held liable for the contamination, and (iii) the other defendants (including IIAA) should be held liable for the contamination because their irregular disposal of toxic material contributed to the environmental damage. On July 22, 2020 IIAA received the official letter establishing its deadline to present its response to the Municipality of Schroeder’s defenses. On October 5, 2020, IIAA presented its defense. IIAA continues to dispute the allegations in the FATMA Notice and intends to continue to vigorously defend itself. Based on our assessment of the facts underlying the claims in the above actions, we are unable to provide meaningful quantification of how the final resolution of these claims may impact our future consolidated financial condition, results of operations, or cash flows. Sao Paulo Groundwater Notice In March 2014, IIAA, along with other nearby companies, received from the Sao Paulo District Attorney (the "District Attorney") a notice and proposed Consent Agreement relating to alleged neighborhood-wide groundwater contamination at or around its Sao Paulo manufacturing facility. The proposed Consent Agreement sought certain groundwater investigations and other technical relief and proposed sanctions in the amount of R $3 million (the equivalent of less than US $1 million at October 31, 2020 ). In November 2014, IIAA extended a settlement offer which was never accepted, rejected or countered by the District Attorney. On August 31, 2016, the District Attorney filed civil actions against IIAA and other companies in the Central Forum of the capital of the State of Sao Paulo seeking soil and groundwater investigation and remediation, together with monetary payment in an unspecified amount. IIAA filed its defense to the civil action on January 26, 2017, alleging that IIAA had made all necessary investigations and had taken remedial measures to address the contamination and that Companhia Ambiental do Estado de Sao Paulo, the environmental agency of Sao Paulo State, had agreed to the remedial measures taken by IIAA. A new district attorney (the “New District Attorney”) assumed responsibility for the case in February 2018. The New District Attorney indicated that it would like the companies involved to try to reach a settlement agreement as to the remediation efforts to be taken after having discussions and negotiations with the New District Attorney’s technical experts. On September 10, 2019, the judge granted the New District Attorney's request to require answers from the Department of Water and Electric Energy ("DAEE") and Sao Paulo State Sewage Company ("SABESP"), but DAEE and SABESP did not provide any additional relevant information. IIAA has not yet received the New District Attorney's opinion. There are no current demands or offers outstanding. Based on our assessment of the facts underlying the claims in the above actions, we are unable to provide meaningful quantification of how the final resolution of these claims may impact our future consolidated financial condition, results of operations, or cash flows. MaxxForce Engine EGR Warranty Litigation On June 24, 2014, N&C Transportation Ltd. ("N&C") filed a putative class action lawsuit against NIC, NI, Navistar Canada Inc., and Harbour International Trucks in Canada in the Supreme Court of British Columbia (the "N&C Action"). Subsequently, seven additional, similar putative class action lawsuits have been filed in various courts in Canada, including Alberta, Manitoba, Ontario, and Quebec (together with the N&C Action, the "Canadian Actions"). On November 16, 2016, the Supreme Court of British Columbia certified a Canada-wide class comprised of persons who purchased heavy-duty trucks equipped with Advanced EGR MaxxForce 11, MaxxForce 13, and MaxxForce 15 engines designed to meet 2010 EPA regulations. On August 1, 2018, the appellate court affirmed the November 2016 decision and certified three additional narrow issues on whether misrepresentations were made in Navistar's advertising materials. The next step will be an attendance before the case management judge regarding the details of the notice of certification to be given to the class. No date for this attendance has been set. On July 7, 2014, Par 4 Transport, LLC filed a putative class action lawsuit against NI in the United States District Court for the Northern District of Illinois (the "Par 4 Action"). Subsequently, seventeen additional putative class action lawsuits were filed in various United States district courts, (together with the Par 4 Action, the "U.S. Actions"). Some of the U.S. Actions named both NIC and NI, and alleged matters substantially similar to the Canadian Actions. More specifically, one or more of the Canadian Actions and the U.S. Actions (collectively, the "EGR Class Actions") seek to certify a class of persons or entities in Canada or the United States who purchased and/or leased a ProStar or other Navistar vehicle equipped with a model year 2008-2013 MaxxForce Advanced EGR engine. In substance, the EGR Class Actions allege that the MaxxForce Advanced EGR engines are defective and that the Company and NI failed to disclose and correct the alleged defect. The EGR Class Actions assert claims based on theories of contract, breach of warranty, consumer fraud, unfair competition, misrepresentation and negligence. The EGR Class Actions seek relief in the form of monetary damages, punitive damages, declaratory relief, interest, fees, and costs. In December 2014, the United States Judicial Panel on Multidistrict Litigation (the "MDL Panel") issued an order consolidating before Judge Joan B. Gottschall of the United States District Court for the Northern District of Illinois all of the U.S. Actions, as well as certain non-class action MaxxForce Advanced EGR engine lawsuits that were pending on October 3, 2014 (the "MDL Action"). In May 2019, the parties completed negotiation of a settlement agreement (the "The Settlement Agreement") to resolve the U.S. Actions. The plaintiffs submitted the Settlement Agreement to the court for preliminary approval on May 28, 2019. The Settlement Agreement class consists of entities and natural persons who owned or leased a 2011-2014 model year vehicle equipped with a MaxxForce 11 or 13 liter engine certified to meet EPA 2010 emissions standards without selective catalytic reduction technology, provided that the vehicle was purchased or leased in the U.S. Among other things, the Settlement Agreement requires that (1) the parties establish a non-reversionary common fund consisting of cash (the “Cash Fund”) and rebates (the “Rebate Fund”) with a total value of $135 million (the “Settlement Fund”); (2) NIC and NI contribute $85 million to the Cash Fund, which will be used to pay all settlement fees and expenses, service awards, attorneys’ fees and costs, and cash payments to members of the settlement class; (3) NI commit to make available rebates with a face value in the aggregate of $50 million to the Rebate Fund; and (4) the settlement class release NIC and NI and their affiliates from all claims and potential claims arising from or related to the allegations in the U.S. Actions, except for claims for personal injury or damage to third-party property. The Settlement Agreement further provides that dollars or value remaining in either the Cash Fund or the Rebate Fund after claims are processed will be used to pay approved claims from the other fund if the other fund is oversubscribed (the “Waterfall”). The Settlement Agreement states that NIC and NI deny all claims in the U.S. Actions, deny wrongdoing, liability or damage of any kind, and deny that NIC and NI acted improperly or wrongfully in any way. Any Waterfall from the Rebate Fund to the Cash Fund is capped at $35 million . We are waiting for the final adjudication of the claims by the administrator. It is possible that a Waterfall from the Rebate F

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The following is a description of our four reporting segments: • Our Truck segment manufactures and distributes Class 4 through 8 trucks and buses under the International and IC Bus ("IC") brands, and produces engines under our proprietary brand name. This segment sells its products in the U.S., Canada, and Mexico markets, as well as through our export truck business. • Our Parts segment provides customers with proprietary products needed to support the International commercial truck, IC Bus, proprietary engine lines, and export parts business, as well as our other product lines. Our Parts segment also provides a wide selection of other standard truck, trailer, and engine aftermarket parts. Also included in the Parts segment are the operating results of BDP, which manages the sourcing, merchandising, and distribution of certain service parts we sell to Ford in North America. • Our Global Operations segment primarily consists of Brazil engine operations which produce diesel engines under contract manufacturing arrangements, as well as under the MWM brand, for sale to OEMs in South America. Global Operations also includes the sale of engine aftermarket parts, primarily in South America. • Our Financial Services segment provides retail, wholesale, and lease financing of products sold by the Truck and Parts segments and their dealers within the U.S. and Mexico, as well as financing for wholesale accounts and selected retail accounts receivable. This segment also facilitates financing relationships in the U.S. and other countries to support our Manufacturing Operations. Corporate contains those items that are not included in our four segments. Segment Profit (Loss) We define segment profit (loss) as net income (loss) from continuing operations attributable to NIC, excluding income tax benefit (expense). Selected financial information from our Consolidated Statements of Operations and our Consolidated Balance Sheets is as follows: • The costs of profit sharing and annual incentive compensation for the Manufacturing operations are included in corporate expenses. • Interest expense and interest income for the Manufacturing operations are reported in corporate expenses. • The Financial Services segment finances certain sales to our dealers in North America, which include an interest-free period that varies in length that is subsidized by our Truck and Parts segments. Additionally, the Financial Services segment reports intersegment revenues from secured and unsecured loans to the Manufacturing operations. Certain retail sales financed by the Financial Services segment, primarily NFC, require the Manufacturing operations, primarily the Truck segment, to share a portion of any credit losses. • We allocate "access fees" to the Parts segment from the Truck segment for certain engineering and product development costs, depreciation expense, and SG&A expenses incurred by the Truck segment based on the relative percentage of certain sales, as adjusted for cyclicality. • Other than the items discussed above, the selected financial information presented below is presented in accordance with our policies described in Note 1, Summary of Significant Accounting Policies.

Stockholders' Deficit

Stockholders' Deficit	12 Months Ended

Equity [Abstract]
Stockholders' Deficit	Stockholders' Deficit Preferred and Preference Stocks NIC has authorized 30 million shares of preferred stock, none of which have been issued, with a par value of $1.00 per share. NIC has authorized 10 million shares of preference stock with a par value of $1.00 per share. Currently, Series B Nonconvertible Junior Preference Stock ("Series B") and Series D Convertible Junior Preference Stock ("Series D") are outstanding. The UAW holds the Series B and is currently entitled to elect one member of our Board of Directors. As of October 31, 2020 and 2019 , there was one share of Series B Preference stock with a par value of $1.00 per share authorized and outstanding. At both October 31, 2020 and 2019 , there were 70,182 shares of Series D issued and outstanding. These shares were issued with a par value of $1.00 per share, an optional redemption price, and a liquidation preference of $25 per share plus accrued dividends. The Series D stock may be converted into NIC common stock at the holder's option (subject to adjustment in certain circumstances); upon conversion each share of Series D stock is converted to 0.3125 shares of common stock. The Series D stock ranks senior to common stock as to dividends and liquidation and receives dividends at a rate of 120% of the cash dividends on common stock as declared on an as-converted basis. Common Stock Changes in shares of common stock and treasury stock were as follows: (in millions) Common Stock Treasury Stock Shares Outstanding Balance as of October 31, 2017 103.1 4.6 98.5 Shares issued — (0.5 ) 0.5 Shares acquired — 0.1 (0.1 ) Balance as of October 31, 2018 103.1 4.2 98.9 Shares issued — (0.5 ) 0.5 Shares acquired — 0.2 (0.2 ) Balance as of October 31, 2019 103.1 3.9 99.2 Shares issued — (0.6 ) 0.6 Shares acquired — 0.2 (0.2 ) Balance as of October 31, 2020 103.1 3.5 99.6 Additional Paid in Capital In accounting for the issuance of the former 4.5% Senior Subordinated Convertible Notes due 2018 ("2018 Convertible Notes"), a debt component and an equity component were separated resulting in the debt component being recorded at its estimated fair value without consideration given to the conversion feature. We estimated the fair value of the liability component at $177 million . The resulting equity component of $22 million , net of $1 million of discount, was recorded in Additional paid in capital . Issuance costs were also allocated between the debt and equity components resulting in an immaterial amount being recorded as a reduction in Additional paid in capital. The 2018 Convertible Notes were fully repaid upon maturity in October 2018, and none were converted into our common stock. In accounting for the issuance of the former 2019 Convertible Notes, the debt component and equity component were separated, resulting in the debt component being recorded at its estimated fair value without consideration given to the conversion feature. We estimated the fair value of the liability component at $367 million . The resulting equity component of $44 million was recorded in Additional paid in capital . Issuance costs were also allocated between debt and equity components with $1 million being recorded as a reduction in Additional paid in capital. The 2019 Convertible Notes were fully repaid upon maturity in April 2019, and none were converted into our common stock. Accumulated Other Comprehensive Loss The following table presents changes in Accumulated other comprehensive loss, net of tax, included in our Consolidated Statements of Shareholders' Deficit : (in millions) Foreign Currency Translation Adjustments Defined Benefit Plans Total Balance as of October 31, 2019 $ (321 ) $ (1,591 ) $ (1,912 ) Other comprehensive income (loss) before reclassifications (A) (83 ) 220 137 Amounts reclassified out of accumulated other comprehensive loss — 102 102 Net current-period other comprehensive income (loss) (83 ) 322 239 Reclassification of stranded tax effects (B) $ — $ (192 ) $ (192 ) Balance as of October 31, 2020 $ (404 ) $ (1,461 ) $ (1,865 ) (in millions) Foreign Currency Translation Adjustments Defined Benefit Plans Total Balance as of October 31, 2018 $ (315 ) $ (1,605 ) $ (1,920 ) Other comprehensive loss before reclassifications (6 ) (178 ) (184 ) Amounts reclassified out of accumulated other comprehensive loss — 192 192 Net current-period other comprehensive income (loss) (6 ) 14 8 Balance as of October 31, 2019 $ (321 ) $ (1,591 ) $ (1,912 ) (in millions) Foreign Currency Translation Adjustments Defined Benefit Plans Total Balance as of October 31, 2017 $ (283 ) $ (1,928 ) $ (2,211 ) Other comprehensive income (loss) before reclassifications (32 ) 201 169 Amounts reclassified out of accumulated other comprehensive loss — 122 122 Net current-period other comprehensive income (loss) (32 ) 323 291 Balance as of October 31, 2018 $ (315 ) $ (1,605 ) $ (1,920 ) _________________________ (A) Other Comprehensive income before reclassifications for Defined Benefit Plans includes a $75 million intraperiod tax allocation. (B) During the fiscal year ended October 31, 2020 , we reclassified $192 million of stranded tax effects out of Accumulated other comprehensive loss and into Accumulated deficit. The stranded tax effects remained a component of Accumulated other comprehensive loss as a result of the remeasurement of our deferred tax assets related to our U.S. Pension and OPEB Plans through the statement of operations, to the new U.S. federal tax rate of 21% through our Consolidated Statement of Operations. As a result, stranded tax effects within Accumulated other comprehensive loss which would not be realized at the established historical tax rates have now been adjusted through equity. The following table presents the amounts reclassified from Accumulated other comprehensive loss and the affected line item in our Consolidated Statements of Operations: For the Years Ended October 31, Location in Consolidated 2020 2019 2018 Defined benefit plans Amortization of pension service cost Other expense, net $ 1 $ — $ — Amortization of actuarial loss Other expense, net 96 93 114 Settlements Other expense, net 7 143 9 Total before tax 104 236 123 Income tax expense (2 ) (44 ) (1 ) Total reclassifications for the period, net of tax $ 102 $ 192 $ 122 Dividend Restrictions Under the General Corporation Law of the State of Delaware, dividends may only be paid out of surplus or out of net profits for the year in which the dividend is declared or the preceding year, and no dividend may be paid on common stock at any time during which the capital of outstanding preferred stock or preference stock exceeds our net assets. Certain debt instruments, including our 6.625% Senior Notes indenture, our 9.50% Senior Secured Notes indenture, our Loan Agreement with regard to the Tax-Exempt Bonds and our Amended Term Loan Credit Agreement, contain terms that include various negative covenants and restrictions, including, among others, certain limitations on dividends. We have not paid dividends on our common stock since 1980.

Earnings Per Share [Abstract]
Loss Per Share Attributable to Navistar International Corporation	Earnings (Loss) Per Share Attributable to Navistar International Corporation The following table presents the information used in the calculation of our basic and diluted earnings (loss) per share attributable to NIC in our Consolidated Statements of Operations : For the Years Ended October 31, (in millions, except per share data) 2020 2019 2018 Numerator: Net income (loss) attributable to Navistar International Corporation common stockholders $ (347 ) $ 221 $ 340 Denominator: Weighted average shares outstanding: Basic 99.7 99.3 98.9 Effect of dilutive securities — 0.2 0.7 Diluted 99.7 99.5 99.6 Earnings (loss) per share attributable to Navistar International Corporation: Basic $ (3.48 ) $ 2.23 $ 3.44 Diluted $ (3.48 ) $ 2.22 $ 3.41 The conversion rate on our former 2018 Convertible Notes was 17.1233 shares of common stock per $1,000 principal amount of 2018 Convertible Notes, equivalent to an initial conversion price of approximately $58.40 per share of common stock. The 2018 Convertible Notes had an anti-dilutive effect when calculating diluted earnings per share when our average stock price was less than $58.40 for all periods presented. The 2018 Convertible Notes were fully repaid upon maturity in October 2018, and none were converted into our common stock. The conversion rate on our former 2019 Convertible Notes was 18.4946 shares of common stock per $1,000 principal amount of 2019 Convertible Notes, equivalent to an initial conversion price of approximately $54.07 per share of common stock. The 2019 Convertible Notes had an anti-dilutive effect when calculating diluted earnings per share when our average stock price was less than $54.07 for all periods presented. The 2019 Convertible Notes were fully repaid upon maturity in April 2019 and none were converted into our common stock. The computation of diluted earnings per share also excludes outstanding options and other common stock equivalents in periods where inclusion of such potential common stock instruments would be anti-dilutive. For the year ended October 31, 2020 , no dilutive securities were included in the computation of diluted earnings per share because they would have been anti-dilutive due to the net loss attributable to NIC. For the year ended October 31, 2018 , certain securities have been excluded from the computation of earnings per share, as our average stock price was less than their respective exercise prices. The aggregate shares not included were 9.8 million , which were primarily comprised of 7.6 million shares related to the 2019 Convertible Notes.

Share-based Payment Arrangement [Abstract]
Share-based Payment Arrangement [Text Block]	19. Stock-based Compensation Plans 2013 Performance Incentive Plan The 2013 Performance Incentive Plan ("2013 PIP") was approved by the Board of Directors on December 11, 2012 and subsequently approved by the stockholders on February 19, 2013. The plan was first amended on February 11, 2015 and then subsequently amended on December 9, 2019. The 2013 PIP provides for the grant of annual cash incentive awards to all employees (including the Company’s executive officers), and stock options, restricted stock or stock unit awards, stock appreciation rights and other stock-based awards to all employees (including the Company’s executive officers), any consultants of the Company and its subsidiaries, and all non-employee directors serving on the Company’s Board of Directors. The awards granted under the 2013 PIP are established by our Board of Directors or a committee thereof at the time of issuance. The 2013 PIP replaced on a prospective basis, our 2004 Performance Incentive Plan, and will expire in February 2023. A total of 3,665,500 shares of common stock were reserved for awards under the 2013 PIP. The number of shares authorized and available for issuance under the 2013 PIP will be increased by shares of stock subject to an option or award under the 2013 PIP, the Company’s 2004 Performance Incentive Plan, or the Ownership Program as further described below, (collectively, the "Existing Plans"), that are canceled, expired, forfeited, settled in cash, or otherwise terminated after February 19, 2013 without a delivery of shares to the participant of such plan, including shares used to satisfy the exercise price of a stock option or a tax withholding obligation arising in connection with an award. As of October 31, 2020 , 3,949,512 shares remain available for issuance under the 2013 PIP. Shares issued under the Plan may be newly issued shares or reissued Treasury shares. Other Plans and Grants The following plans were approved by our Board of Directors but were not approved and were not required to be approved by our stockholders: the Executive Stock Ownership Program, as amended from time to time (the "Ownership Program"), and the Non-Employee Directors Deferred Fee Plan (the "Deferred Fee Plan"). • Ownership Program —In June 1997, our Board of Directors approved the terms of the Ownership Program. In general, under the Ownership Program in existence through November 2013, all officers and senior managers were required to acquire, by direct purchase or through salary or annual bonus reduction, an ownership interest in the Company by acquiring a designated amount of our common stock based on organizational level. Participants were required to hold such stock for the entire period in which they are employed by the Company. The Ownership Program was amended and restated effective November 1, 2013 on a going forward basis. The new guidelines (i) increased stock ownership guideline multiples to six times salary for the President and CEO and up to three times salary for other senior executives; (ii) modified retention requirements for Company granted equity until ownership requirements are met; (iii) added a holding period for shares acquired through transactions with Company granted equity after the executives satisfy the stock ownership requirement; (iv) eliminated the granting of premium shares as an inducement to executives fulfilling stock ownership guidelines on an accelerated basis; and (v) eliminated the required time frame to fulfill stock ownership guidelines. Under the prior Ownership Program, participants were entitled to defer their cash bonus into deferred share units ("DSUs"), which vested immediately. There were 2,365 DSUs outstanding as of October 31, 2020 . Premium share units ("PSUs") were also eligible to be awarded to participants who complete their ownership requirement on an accelerated basis. PSUs vested annually, pro rata over three years . There were 28,500 PSUs outstanding as of October 31, 2020 under the prior Ownership Program. Each vested DSU and PSU will be settled by delivery of one share of common stock within 10 days after a participant's termination of employment or at such later date as required by IRC Section Rule 409A. PSUs and DSUs awarded between February 19, 2013 and October 31, 2013 were issued under the 2013 PIP. • Deferred Fee Plan —Under the Deferred Fee Plan, non-employee directors may elect to defer payment of all or a portion of their annual cash retainer in cash (with interest) or in stock units and may elect to defer all or a portion of their annual equity retainer in deferred stock units. Deferrals in the deferred stock account are valued as if each deferral was vested in NIC common stock as of the deferral date. As of October 31, 2020 , 28,833 deferred shares were outstanding under the Deferred Fee Plan. Beginning on September 30, 2013, shares deferred by non-employee directors have been issued out of the 2013 PIP. The Deferred Fee Plan was amended and restated effective February 11, 2015 and then subsequently amended on December 9, 2019. Stock Options Stock options represent the right to purchase a specified number of shares of common stock at a specified exercise price. Generally, stock options are awarded with an exercise price equal to the fair market value of the common stock at grant date. The stock options granted prior to December 2009 generally have a ten -year contractual life. Stock options granted in December 2009 through November 2016 were granted with a seven -year contractual life. Since December 2016, stock options have been granted with a ten-year contractual life. Stock options are valued using the Black-Scholes option pricing model and vest ratably over a three -year period. The following table summarizes stock options activity: For the Years Ended October 31, 2020 2019 2018 Shares Weighted Average Exercise Price Shares Weighted Average Exercise Price Shares Weighted Average Exercise Price (in thousands) (in thousands) (in thousands) Options outstanding, at beginning of year 1,737 $ 33.82 1,780 $ 33.70 2,408 $ 38.81 Granted — — 284 33.83 236 40.44 Exercised (142 ) 28.81 (94 ) 23.98 (236 ) 32.78 Forfeited/expired (661 ) 33.65 (233 ) 36.86 (628 ) 56.64 Options outstanding, at end of year 934 34.71 1,737 33.82 1,780 33.70 Options exercisable, at end of year 686 34.35 1,242 33.50 1,396 33.55 The following table summarizes information about stock options outstanding: Shares Weighted Average Remaining Contractual Life Weighted Average Exercise Price Aggregate Intrinsic Value Range of Exercise Prices: (in thousands) (in years) (in millions) $ 10.60 - $ 30.94 261 6.3 $ 26.72 $ 4.3 $ 30.95 - $ 39.32 410 4.9 35.35 3.2 $ 39.33 - $ 43.86 263 5.2 41.61 0.5 Options Outstanding 934 The following table summarizes information about stock options exercisable: Shares Weighted Average Remaining Contractual Life Weighted Average Exercise Price Aggregate Intrinsic Value Range of Exercise Prices: (in thousands) (in years) (in millions) $ 10.60 - $ 30.94 237 6.1 $ 26.66 $ 3.9 $ 30.95 - $ 39.32 249 2.8 35.55 1.9 $ 39.33 - $ 43.86 200 4.5 41.93 0.3 Options Exercisable 686 There were no options granted during the year ended October 31, 2020 . The weighted average grant date fair value of options granted during the years ended October 31, 2019 , and 2018 was $16.15 , and $18.90 , respectively. The total intrinsic value of stock options exercised during the years ended October 31, 2020 , 2019 , and 2018 was $1 million , $2 million , and $3 million , respectively. The fair value of each option grant was estimated on the grant date using the Black-Scholes option-pricing model. The following table summarizes the annual weighted average assumptions: For the Years Ended October 31, 2020 2019 2018 Risk-free interest rate N/A 2.5 % 2.5 % Expected volatility N/A 48.8 % 49.1 % Expected life (in years) N/A 5.6 5.3 The use of the Black-Scholes option-pricing model requires us to make certain estimates and assumptions. The risk-free interest rate utilized is the implied yield on U.S. Treasury zero-coupon issues with a remaining term equal to the expected term assumption on the grant date, rounded to the nearest half year. A dividend yield assumption of 0% is used for all grants based on our history of not paying a dividend to any class of stock and future expectations. Expected volatility is based on a blend of our historical stock prices and implied volatilities from traded options in our stock. The weighted average expected life in years for all grants as a group is then calculated for each year. Restricted Stock Restricted stock represents common stock issued subject to forfeiture or other restrictions that will lapse upon satisfaction of specified conditions. Restricted stock is valued based on the fair value of the common stock at grant date and except for the restricted stock issued to non-employee directors, vests either ratably over a three -year period or cliff-vest at the end of a three -year period. Restricted stock issued to non-employee directors in the years ended October 31, 2019 and 2018 represents their first quarterly retainer fees and immediately vests at grant date. No restricted stock was issued for the year ended October 31, 2020.

Restricted Stock Units Restricted stock units ("RSUs") represent the right to receive shares of common stock ("share-settled RSUs") or the cash ("cash-settled RSUs") value of one share of common stock in the future, with the right to future delivery of the shares or cash subject to forfeiture or other restrictions that will lapse upon satisfaction of specified conditions. Share and cash-settled RSUs are valued based on the fair value of the common stock at grant date and vest either ratably over a three -year period or cliff-vest at the end of a one-year or three -year period. Cash-settled RSUs are classified as liabilities and are remeasured at each reporting date until settlement.

Performance-based Stock Options Performance-based stock options represent the right to receive shares of common stock in the future, with the right to future delivery of the shares subject to forfeiture or other restrictions that will lapse upon satisfaction of a combination of the following conditions: service, market and performance conditions. Performance-based stock options have a seven -year contractual life. Performance-based stock options subject to service and performance conditions are valued using the Black-Scholes option pricing model and cliff-vest at the end of a three -year period if performance measures are met. Performance-based stock options subject to service and market conditions are valued using a Monte Carlo simulation and cliff-vest at the end of a three -year period if performance measures are met.

There was minimal intrinsic value for performance-based options exercised during the year ended October 31, 2019. Performance-based Stock Units Performance-based stock units ("PUs") represent the right to receive one share of common stock ("share-settled PUs") or cash equal to the value of one share of common stock ("cash-settled PUs") in the future, with the right to future delivery of the shares or cash subject to forfeiture or other restrictions that will lapse upon satisfaction of a combination of the following conditions: service, market, and performance conditions. Share and cash-settled PUs subject to service and performance conditions are valued based on the fair value of the common stock at grant date and vest either at the end of the performance period or cliff-vest at the end of a three -year period if performance measures are met. Cash-settled PUs subject to service and market conditions are valued using a Monte Carlo simulation and cliff-vest at the end of a three -year period if performance measures are met. Cash-settled PUs are classified as liabilities and are remeasured at each reporting date until settlement. There were no nonvested share-settled PUs subject to service and performance conditions, nor any cash-settled PUs subject to service and market conditions outstanding for the years ended October 31, 2020 , 2019 , and 2018 . The following tables summarize cash-settled PUs activity for the years ended October 31: Cash-Settled PUs subject to Service and Performance Conditions 2020 2019 2018 Shares Weighted Average Grant Date Fair Value Shares Weighted Average Grant Date Fair Value Shares Weighted Average Grant Date Fair Value (in thousands) (in thousands) (in thousands) Nonvested, at beginning of year — $ — — $ — 220 $ 27.59 Granted — — — — — — Vested — — — — (121 ) 27.59 Forfeited — — — — (99 ) 27.59 Nonvested, at end of year — — — — — — Total Share-Based Compensation Expense Total share-based compensation expense for the years ended October 31, 2020 , 2019 , and 2018 was $11 million , $17 million and $17 million , respectively. We record share-based compensation expense on a straight-line basis over the required service period which is equal to the vesting period, beginning on the grant date. Share-based compensation expense is included in Selling, general and administrative expenses in the Consolidated Statements of Operations . As of October 31, 2020 , there was $5 million of total unrecognized compensation expense related to non-vested share-based awards which is expected to be recognized over a weighted average period of approximately one year . We received cash of $4 million , $4 million , and $8 million during the years ended October 31, 2020 , 2019 and 2018 , respectively, related to stock options exercised. We used cash of $7 million , $8 million , and $13 million during the years ended October 31, 2020 , 2019 , and 2018 , respectively, to settle cash-settled RSUs. We did no t realize any tax benefit from stock options exercised for fiscal years 2020 , 2019 and 2018 .

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On November 7, 2020, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with TRATON SE, a Societas Europaea (“Parent”) and Dusk Inc., a Delaware corporation and a wholly owned indirect subsidiary of Parent (“Merger Subsidiary”), pursuant to which Merger Subsidiary will be merged with and into the Company (the “Merger”), with the Company continuing as the surviving company in the Merger as a wholly owned indirect subsidiary of Parent (the “Surviving Corporation”). Subject to the terms and conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), (a) each share of common stock of the Company, par value $0.10 per share (“Company Stock”) outstanding immediately prior to the Effective Time, unless otherwise provided by the Merger Agreement, shall be automatically canceled and converted into the right to receive $44.50 in cash, without interest (the “Common Merger Consideration”); (b) each share of Series D Convertible Junior Preference Stock of the Company, par value $1.00 per share (“Series D Stock”) outstanding immediately prior to the Effective Time, unless otherwise provided in the Merger Agreement, shall be automatically canceled and converted into an amount in cash, without interest, equal to the portion of the Common Merger Consideration that would have been payable in respect of such share of Series D Stock had such share of Series D Stock been converted into Company Stock pursuant to the terms of the certificate of incorporation of the Company in effect immediately prior to the Effective Time; and (c) the sole share of Series B Nonconvertible Junior Preference Stock of the Company, par value $1.00 (“Series B Stock”), issued and outstanding immediately prior to the Effective Time, shall be unaffected by the Merger and shall remain outstanding as one share of Series B Stock of the Surviving Corporation, with the same rights, powers, preferences and privileges attributable to the sole share of Series B Stock immediately prior to the Effective Time. Consummation of the Merger is subject to various closing conditions, including, (i) the adoption of the Merger Agreement by the affirmative vote of the holders of a majority of the outstanding shares of Company Stock entitled to vote on such matter at a meeting of the Company’s stockholders, (ii) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as well as certain non-U.S. regulatory approvals, and (iii) the absence of any law or order (whether temporary, preliminary or permanent) by a governmental entity that restrains or otherwise prohibits the Merger or the other transactions contemplated by the Merger Agreement. The Merger Agreement also contains customary representations, warranties and covenants of the Company, Parent and Merger Subsidiary. The Company has also made certain covenants in the Merger Agreement, including covenants regarding the operation of the business of the Company and its subsidiaries prior to the Effective Time. The Merger Agreement may be terminated by each of the Company and Parent under certain circumstances, including if the Merger is not consummated by September 30, 2021 (the “End Date”), provided that the End Date may be automatically extended until December 31, 2021 if (a) all of the conditions to the closing of the Merger are satisfied other than the receipt of regulatory approvals or approval from the Committee on Foreign Investment in the United States (“CFIUS”), or (b) if a CFIUS filing request is received by the parties prior to the closing of the Merger; provided further that no party may terminate the Merger Agreement if such party’s breach resulted in or caused the failure of a condition to consummate the Merger by the End Date. The Merger Agreement also provides for certain other customary termination rights for the Company and Parent, and further provides that a termination fee in the amount of $125,000,000 will be payable by the Company to Parent in connection with the termination of the Merger Agreement under certain specified circumstances. In the event that the stockholders of the Company do not approve the Merger at the Company’s stockholder meeting, the Company shall reimburse Parent and its affiliates for 100% of their documented out-of-pocket fees and expenses in an amount up to $25,000,000 actually incurred in connection with the Merger Agreement. If the Company is required to pay Parent the termination fee and to reimburse Parent for its expenses, the termination fee will be reduced by the amount paid as reimbursement for out-of-pocket fees and expenses of Parent, such that the Company will not be required to pay an amount in excess of $125,000,000 . The Company and Parent have agreed to use their reasonable best efforts to obtain the necessary regulatory approvals to consummate the Merger, including preparing and filing all notices, reports and other filings and defending through litigation any proceeding seeking to prevent the Merger.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Oct. 31, 2020
Accounting Policies [Abstract]
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment We report land, buildings, leasehold improvements, machinery and equipment (including tooling and pattern equipment), furniture, fixtures, and equipment, and equipment leased to others at cost, net of depreciation. We initially record assets under finance lease obligations at the present value of the aggregate future minimum lease payments. We depreciate our assets using the straight-line method over the shorter of the lease term or the estimated useful lives of the assets. The ranges of estimated useful lives are as follows: Years Buildings 20 - 50 Leasehold improvements 3 - 20 Machinery and equipment 3 - 12 Furniture, fixtures, and equipment 3 - 15 Equipment leased to others 1 - 10 Long-lived assets are evaluated periodically to determine if an adjustment to the depreciation and amortization period or to the unamortized balance is warranted. Such evaluation is based principally on the expected utilization of the long-lived assets. We depreciate trucks, tractors, and trailers leased to customers under operating lease agreements on a straight-line basis to the equipment's estimated residual value over the lease term. The residual values of the equipment represent estimates of the value of the assets at the end of the lease contracts and are initially recorded based on estimates of future market values. Realization of the residual values is dependent on our future ability to market the equipment. We review residual values periodically to determine that recorded amounts are appropriate, and the equipment is not impaired. Maintenance and repairs of property and equipment are expensed as incurred. We capitalize replacements and improvements that increase the estimated useful life or productive capacity of an asset and we capitalize interest on major construction and development projects while in progress. Gains or losses on disposition of property and equipment are recognized in Other expense, net . We test for impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying value of an asset or asset group (hereinafter referred to as "asset group") may not be recoverable by comparing the sum of the estimated undiscounted future cash flows expected to result from the operation of the asset group and its eventual disposition to the carrying value. During 2020, we identified a triggering event related to our operations in Brazil due to the impacts of the COVID-19 pandemic, which resulted in declines in actual and forecasted results. We performed an impairment test as of April 30, 2020 on the long-lived assets of the Brazilian asset group. As a result, we recorded impairment charges of $12 million in our Global Operations segment. We also concluded that we had triggering events related to certain trucks under operating leases, due to declines in expected residual values, and certain other long-lived assets. As a result, we recorded charges of $10 million and $6 million , respectively, in our Truck segment. It is reasonably possible that within the next twelve months, we could recognize additional impairment charges for certain trucks under operating leases where Navistar is a lessor, which could be material, if we experience continued declines in excess of our forecasted expected residual values, as a result of the COVID-19 pandemic, the demand for used trucks or a change in the mix of sales through various market channels. During 2019, we identified a triggering event related to continued economic weakness in Brazil and the initiation of strategic cost reduction actions in the Brazilian asset group, which is included in the Global Operations segment. As a result, we estimated the recoverable amount of the asset group and determined that the sum of the undiscounted future cash flows exceeds the carrying value and the asset group was not impaired. For more information regarding asset impairment charges see Note 3, Restructuring, Impairments and Divestitures . Included in equipment leased to others are trucks that we produced or acquired to lease to customers as well as equipment that is financed by Bank of Montreal ("BMO") that does not qualify for revenue recognition, as we retained control of the leased property, which are accounted for as operating leases. In the Consolidated Statement of Cash Flows, the related expenditures are reflected as the Purchases of equipment leased to others in the investing section.
Standard Product Warranty, Policy [Policy Text Block]	Warranty We generally offer one to five -year warranty coverage for our truck, bus, and engine products, as well as our service parts. Terms and conditions vary by product, customer, and country. We accrue warranty related costs under standard warranty terms and for certain claims outside the contractual obligation period that we choose to pay as accommodations to our customers. Our warranty estimates are established using historical information about the nature, frequency, timing, and average cost of warranty claims. Warranty claims are influenced by numerous factors, including new product introductions, technological developments, the competitive environment, the design and manufacturing process, and the complexity and related costs of component parts. We estimate our warranty accrual for our engines and trucks based on engine types and model years. Our warranty accruals take into account the projected ultimate cost-per-unit ("CPU") utilizing historical claims information. The CPU represents the total cash projected to be spent for warranty claims for a particular model year during the warranty period, divided by the number of units sold. The projection of the ultimate CPU is affected by component failure rates, repair costs, and the timing of failures in the product life cycle. Warranty claims inherently have a high amount of variability in timing and severity and can be influenced by external factors. Our warranty estimation process takes into consideration numerous variables that contribute to the precision of the estimate, but also add to the complexity of the model. Including numerous variables also reduces the sensitivity of the model to any one variable. We perform periodic reviews of warranty spend data to allow for timely consideration of the effects on warranty accruals. Initial warranty estimates for new model year products are based on the previous model year product's warranty experience until the new product progresses sufficiently through its life cycle and related claims data becomes mature. Historically, warranty claims experience for launch-year products has been higher compared to the prior model-year engines; however, over time we have been able to refine both the design and manufacturing process to reduce both the volume and the severity of warranty claims. New product launches require a greater use of judgment in developing estimates until historical experience becomes available. We record adjustments to pre-existing warranties for changes in our estimate of warranty costs for products sold in prior fiscal years. Such adjustments typically occur when claims experience deviates from historic and expected trends. Future events and circumstances could materially change these estimates and require additional adjustments to our liability. When we identify cost effective opportunities to address issues in products sold or corrective actions for safety issues, we initiate product recalls or field campaigns. As a result of the uncertainty surrounding the nature and frequency of product recalls and field campaigns, the liability for such actions is generally recorded when we commit to a product recall or field campaign. Each subsequent quarter after a recall or campaign is initiated the recorded liability balance is analyzed, reviewed, and adjusted if necessary to reflect any changes in the anticipated average cost of repair or number of repairs to be completed prospectively. Included in 2020 warranty expense were $23 million of charges related to new campaign issuances as well as changes in estimates of previously issued campaigns, as compared to $27 million and $10 million in 2019 and 2018 , respectively. The charges were primarily recognized as adjustments to pre-existing warranties. As we continue to identify opportunities to improve the design and manufacturing of our engines we may incur additional charges for product recalls and field campaigns to address identified issues. Optional extended warranty contracts can be purchased for periods ranging from one to ten years. Warranty revenues related to extended warranty contracts are amortized to income, over the life of the contract, (a) in 2020 and 2019 in proportion to the costs expected to be incurred in satisfying the obligation under the contract and (b) in 2018 using the straight-line method. Costs under extended warranty contracts are expensed as incurred. We recognize losses on defined pools of extended warranty contracts when the expected costs for a given pool of contracts exceed related unearned revenue. When collection is reasonably assured, we also estimate the amount of warranty claim recoveries to be received from our suppliers and record them in Other current assets and Other noncurrent assets . Recoveries related to specific product recalls, in which a supplier confirms its liability under the recall, are recorded in Trade and other receivables, net . Warranty costs and recoveries are included in Costs of products sold . Although we believe that the estimates and judgments discussed herein are reasonable, actual results could differ and we may be exposed to increases or decreases in our warranty accrual that could be material. Product Warranty Liability The following table presents accrued product warranty and deferred warranty revenue activity: For the Years Ended October 31, (in millions) 2020 2019 2018 Balance at beginning of period $ 510 $ 529 $ 629 Costs accrued and revenues deferred 162 249 211 Adjustments to pre-existing warranties (A) 40 3 (9 ) Payments and revenues recognized (263 ) (283 ) (303 ) Other adjustments (B) — 12 1 Balance at end of period 449 510 529 Less: Current portion 209 233 255 Noncurrent accrued product warranty and deferred warranty revenue $ 240 $ 277 $ 274 ________________________ (A) Adjustments to pre-existing warranties reflect changes in our estimate of warranty costs for products sold in prior fiscal periods. Such adjustments typically occur when claims experience deviates from historic and expected trends. Our warranty liability is generally affected by component failure rates, repair costs, and the timing of failures. Future events and circumstances related to these factors could materially change our estimates and require adjustments to our liability. In addition, new product launches require a greater use of judgment in developing estimates until historical experience becomes available. (B) Other adjustments in 2019 include a $14 million increase in revenues deferred in connection with the adoption of the new revenue standard (as defined below regarding Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 606), partially offset by a $2 million reduction in liability related to the sale of a majority interest in our defense business, Navistar Defense. In 2018 , Other adjustments relates to $1 million currency translation adjustments. In 2020 , we recognized an immaterial net benefit related to extended warranty contracts on our proprietary big-bore engines. In 2019 , we recognized a net benefit of $14 million related to extended warranty contracts on our proprietary big-bore engines, which included a benefit of $13 million related to pre-existing warranties. In 2018 , we recognized a net benefit of $29 million related to extended warranty contracts on our proprietary big-bore engines, which included a benefit of $33 million related to pre-existing warranties.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquired business over the amounts assigned to the net assets. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently, if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that the carrying amount is more likely than not higher than the fair value, goodwill is tested for impairment based on a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, thus the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The income approach is based on discounted cash flows which are derived from internal forecasts and economic expectations for each respective reporting unit. An intangible asset determined to have an indefinite useful life is not amortized until its useful life is determined to no longer be indefinite. Indefinite-lived intangible assets are evaluated each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of the indefinite-lived intangible asset with its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Significant judgment is applied when evaluating if an intangible asset has a finite useful life. In addition, for indefinite-lived intangible assets, significant judgment is applied in testing for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, and incorporating general economic and market conditions. Intangible assets subject to amortization are also evaluated for impairment or when indicators of impairment are determined to exist. We test for impairment of intangible assets, subject to amortization, by comparing the sum of the estimated undiscounted future cash flows expected to result from the operation of the asset group and its eventual disposition to the carrying value. If the sum of the undiscounted future cash flows is less than the carrying value, the fair value of the asset group is determined. The amount of impairment is calculated by subtracting the fair value of the asset group from the carrying value of the asset group. Intangible assets, subject to amortization, could become impaired in the future or require additional charges as a result of declines in profitability due to changes in volume, market pricing, cost, manner in which an asset is used, physical condition of an asset, laws and regulations, or the business environment. We amortize the cost of intangible assets over their respective estimated useful lives, generally on a straight-line basis. The ranges for the amortization periods are generally as follows: Years Customer base and relationships 3 - 15 Trademarks 20 Other 3 - 18
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying audited consolidated financial statements include the assets, liabilities, and results of operations of our Manufacturing operations and our Financial Services operations, including VIEs of which we are the primary beneficiary. The effects of transactions among consolidated entities have been eliminated to arrive at the consolidated amounts.
Variable Interest Entities	Variable Interest Entities We have an interest in several VIEs, primarily joint ventures, established to manufacture or distribute products and enhance our operational capabilities. We have determined for certain of our VIEs that we are the primary beneficiary because we have the power to direct the activities of the VIE that most significantly impact its economic performance and we have the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. Accordingly, we include in our consolidated financial statements the assets and liabilities and results of operations of those entities, even though we may not own a majority voting interest. The liabilities recognized as a result of consolidating these VIEs do not represent additional claims on our general assets; rather they represent claims against the specific assets of these VIEs. Assets of these entities are not readily available to satisfy claims against our general assets. We are the primary beneficiary of our Blue Diamond Parts, LLC ("BDP") joint venture with Ford Motor Company ("Ford"). As a result, our Consolidated Balance Sheets include assets of $37 million and $32 million , and liabilities of $3 million and $4 million , as of October 31, 2020 and 2019 , respectively. Assets include $4 million and $2 million of cash and cash equivalents as of October 31, 2020 and 2019 , respectively, which are not readily available to satisfy claims against our general assets. The creditors of BDP do not have recourse to our general credit. In October 2019, Ford notified the Company of its intention to dissolve the BDP joint venture effective October 2021. Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include secured assets of $661 million and $927 million as of October 31, 2020 and 2019 , respectively, and liabilities of $610 million and $838 million as of October 31, 2020 and 2019 , respectively, all of which are involved in securitizations that are treated as asset-backed debt. In addition, our Consolidated Balance Sheets include secured assets of $397 million and $537 million as of October 31, 2020 and 2019 , respectively, and corresponding liabilities of $288 million and $279 million , at the respective dates, which are related to other secured transactions that do not qualify for sale accounting treatment, and therefore, are treated as borrowings secured by operating and finance leases. Investors that hold securitization debt have a priority claim on the cash flows generated by their respective securitized assets to the extent that the related VIEs are required to make principal and interest payments. Investors in securitizations of these entities have either no recourse, or limited recourse, to our general credit. We also have an interest in other VIEs, which we do not consolidate because we are not the primary beneficiary. Our financial support and maximum loss exposure relating to these non-consolidated VIEs are not material to our financial condition, results of operations, or cash flows. We use the equity method to account for our investments in entities that we do not control under the voting interest or variable interest models, but where we can exercise significant influence over operating and financial policies. Equity in income of non-consolidated affiliates includes our share of the net income of these entities.
Equity Method Investments [Policy Text Block]	We use the equity method to account for our investments in entities that we do not control under the voting interest or variable interest models, but where we can exercise significant influence over operating and financial policies. Equity in income of non-consolidated affiliates includes our share of the net income of these entities. Related Party Transactions We have a series of commercial relationships and agreements with TRATON SE and certain of its subsidiaries and affiliates ("TRATON Group"), who holds 16.8% of our common stock, for royalties related to use of certain engine technology, contract manufacturing operations performed by us, the sale of engines, the sale and purchase of parts, and a procurement joint venture. We also have development agreements with TRATON Group involving certain engine and transmission projects. This development work is being expensed as incurred. During the third quarter of 2020, we informed MAN, a subsidiary of the TRATON Group, of the cancellation of a certain engine program. The parties disagree about the effects of the cancellation under the terms of the applicable agreement and are having commercial discussions related to the consequences of the program cancellation. The ultimate resolution may result in additional expenses which could be material. We are unable to estimate the amount of these expenses at this time. Revenue recognized for the years ended October 31, 2020 , 2019 and 2018 was approximately $122 million , $157 million and $146 million , respectively. Net expenses incurred for the years ended October 31, 2020 , 2019 and 2018 were $48 million , $37 million and $27 million , respectively, included primarily in Engineering and product development costs in our Consolidated Statements of Operations. Our receivable from TRATON Group was $18 million and $13 million as of October 31, 2020 and 2019 , respectively. Our payable to TRATON Group was $90 million and $55 million as of October 31, 2020 and 2019 , respectively. We have an exclusive long-term agreement to supply military and commercial parts and chassis to our former defense business, ND Holdings, LLC (“Navistar Defense”), in which we retain a 30% ownership interest. We also entered into an intellectual property agreement and a transition services agreement. For the years ended October 31, 2020 and 2019 , revenue recognized was approximately $48 million and $57 million , respectively. As of October 31, 2020 and 2019 , our receivables from Navistar Defense were $8 million and $29 million , respectively. Cash and Cash Equivalents All highly liquid financial instruments with original maturities of 90 days or less, consisting primarily of U.S. Treasury bills, federal agency securities, and commercial paper, are classified as cash equivalents. Restricted cash is related to our securitization facilities, senior and subordinated floating rate asset-backed notes, wholesale trust agreements, indentured trust agreements, letters of credit, Environmental Protection Agency ("EPA") requirements, and workers compensation requirements. The restricted cash and cash equivalents for our securitized facilities are restricted to pay interest expense, principal, or other amounts associated with our securitization agreements. Derivative Instruments We utilize derivative instruments to manage certain exposure to changes in foreign currency exchange rates, interest rates, and commodity prices. The fair values of all derivative instruments are recognized as assets or liabilities at the balance sheet date. Changes in the fair value of these derivative instruments are recognized in our operating results or included in AOCL , depending on whether the derivative instrument is a fair value or cash flow hedge and whether it qualifies for hedge accounting treatment. We elected to apply the normal purchase and normal sale exclusion to certain commodity contracts that are entered into to be used in production within a reasonable time during the normal course of business. For the years ended October 31, 2020 , 2019 , and 2018 , we elected not to use hedge accounting and all changes in the fair value of our derivatives, except for those qualifying under the normal purchases and normal sales exception, were recognized in our operating results. Gains and losses on derivative instruments are recognized in Costs of products sold , Interest expense , or Other expense, net depending on the underlying exposure. The exchange of cash associated with derivative transactions is classified in the Consolidated Statements of Cash Flows in the same category as the cash flows from the items subject to the economic hedging relationships. Trade and Finance Receivables Trade Receivables Trade accounts receivable and trade notes receivable primarily arise from sales of goods to independently owned and operated dealers, original equipment manufacturers ("OEMs"), and commercial customers in the normal course of business. Finance Receivables Finance receivables consist of the following: • Retail notes —Retail notes primarily consist of fixed rate loans to commercial customers to facilitate their purchase of new and used trucks, and related equipment. • Finance leases —Finance leases consist of direct financing leases to commercial customers for acquisition of new and used trucks, and related equipment. • Wholesale notes —Wholesale notes primarily consist of variable rate loans to our dealers for the purchase of new and used trucks, and related equipment. • Retail accounts —Retail accounts consist of short-term accounts receivable that finance the sale of products to commercial customers. • Wholesale accounts —Wholesale accounts consist of short-term accounts receivable primarily related to the sales of items other than trucks, and related equipment (e.g. service parts) to dealers. Finance receivables are classified as held-to-maturity and are recorded at gross value less unearned income and are reported net of allowances for doubtful accounts. Unearned revenue is amortized to revenue over the life of the receivable using the effective interest method. Our Financial Services operations purchase the majority of the wholesale notes receivable and accounts receivable arising from our Manufacturing operations. The Financial Services operations retain as collateral a security interest in the equipment associated with retail notes, wholesale notes, and finance leases. Sales of Trade and Finance Receivables We sell finance receivables using a process commonly known as securitization, whereby asset-backed securities are sold via public offering or private placement. None of our securitizations qualify for sales accounting treatment or as an off-balance sheet arrangement. As a result, the transferred receivables and the associated secured borrowings are included in our Consolidated Balance Sheets and no gain or loss is recorded on the sale. We also act as servicer of transferred receivables. The servicing duties include collecting payments on receivables and preparing monthly investor reports on the performance of the receivables that are used by the trustee to distribute monthly interest and principal payments to investors. While servicing the receivables, we apply the same servicing policies and procedures that are applied to our owned receivables. On a limited basis, we have sold certain receivables to third party lenders, without recourse or future obligations, and generally with no gain or loss. Allowance for Doubtful Accounts An allowance for doubtful accounts is established through a charge to Selling, general and administrative ("SG&A") expenses . The allowance is an estimate of the amount required to absorb probable losses on trade and finance receivables that may become uncollectible. The receivables are charged off when amounts due are determined to be uncollectible. We have two portfolio segments of finance receivables based on the type of financing inherent to each portfolio. The retail portfolio segment represents loans or leases to end-users for the purchase or lease of vehicles. The wholesale portfolio segment represents loans to dealers to finance their inventory. As the initial measurement attributes and the monitoring and assessment of credit risk or the performance of the receivables are consistent within each of our receivable portfolios, we determined that each portfolio consisted of one class of receivable. Impaired receivables are specifically identified and segregated from the remaining portfolio. The expected loss on impaired receivables is fully reserved in a separate calculation as a specific reserve based on the unique ability of the customer to pay the estimated value of the collateral. The historical loss experience and portfolio quality trends of the retail portfolio segment compared to the wholesale portfolio segment are inherently different. A specific reserve on impaired retail receivables is recorded if the estimated fair value of the underlying collateral, net of selling costs, is less than the principal balance of the receivable. We calculate a general reserve on the remaining loan portfolio by applying loss ratios which are determined using actual loss experience and customer payment history, in conjunction with current economic and portfolio quality trends. To establish a specific reserve for impaired wholesale receivables, we consider the same factors discussed above but also consider the financial strength of the dealer and key management, the timeliness of payments, the number and location of satellite locations, the number of dealers of competitor manufacturers in the market area, the type of equipment normally financed, and the seasonality of the business. Repossessions Gains or losses arising from the sale of repossessed collateral supporting finance receivables and operating leases are recognized in Other expense, net . Repossessed assets are recorded within Inventories at the lower of historical cost or fair value, less estimated costs to sell. Inventories Inventories are valued at the lower of cost and net realizable value ("NRV"). Cost is principally determined using the first-in, first-out method. Our gross used truck inventory was $135 million at October 31, 2020 compared to $200 million at October 31, 2019 , offset by reserves of $37 million in both periods. In valuing our used truck inventory, we are required to make assumptions regarding the level of reserves required to value inventories at their NRV. Our judgments and estimates for used truck inventory are based on an analysis of current and forecasted sales prices, aging of and demand for used trucks, and the mix of sales through various market channels. The NRV is subject to change based on numerous conditions, including age, specifications, mileage, timing of sales, market mix and current and forecasted pricing. While calculations are made after taking these factors into account, significant management judgment regarding expectations for future events is involved. Future events that could significantly influence our judgment and related estimates include general economic conditions in markets where our products are sold, actions of our competitors, and the ability to sell used trucks in a timely manner. The following table presents our used truck reserve: For the Years Ended October 31, (in millions) 2020 2019 2018 Balance at beginning of period $ 37 $ 31 $ 110 Additions charged to expense (A) 99 69 50 Deductions/Other adjustments (B) (99 ) (63 ) (129 ) Balance at end of period $ 37 $ 37 $ 31 _________________________ (A) Additions charged to expense reflects the increase of the reserve for inventory on hand. (B) Deductions/Other adjustments include reductions of the reserve related to the sale of units. Property and Equipment We report land, buildings, leasehold improvements, machinery and equipment (including tooling and pattern equipment), furniture, fixtures, and equipment, and equipment leased to others at cost, net of depreciation. We initially record assets under finance lease obligations at the present value of the aggregate future minimum lease payments. We depreciate our assets using the straight-line method over the shorter of the lease term or the estimated useful lives of the assets. The ranges of estimated useful lives are as follows: Years Buildings 20 - 50 Leasehold improvements 3 - 20 Machinery and equipment 3 - 12 Furniture, fixtures, and equipment 3 - 15 Equipment leased to others 1 - 10 Long-lived assets are evaluated periodically to determine if an adjustment to the depreciation and amortization period or to the unamortized balance is warranted. Such evaluation is based principally on the expected utilization of the long-lived assets. We depreciate trucks, tractors, and trailers leased to customers under operating lease agreements on a straight-line basis to the equipment's estimated residual value over the lease term. The residual values of the equipment represent estimates of the value of the assets at the end of the lease contracts and are initially recorded based on estimates of future market values. Realization of the residual values is dependent on our future ability to market the equipment. We review residual values periodically to determine that recorded amounts are appropriate, and the equipment is not impaired. Maintenance and repairs of property and equipment are expensed as incurred. We capitalize replacements and improvements that increase the estimated useful life or productive capacity of an asset and we capitalize interest on major construction and development projects while in progress. Gains or losses on disposition of property and equipment are recognized in Other expense, net . We test for impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying value of an asset or asset group (hereinafter referred to as "asset group") may not be recoverable by comparing the sum of the estimated undiscounted future cash flows expected to result from the operation of the asset group and its eventual disposition to the carrying value. During 2020, we identified a triggering event related to our operations in Brazil due to the impacts of the COVID-19 pandemic, which resulted in declines in actual and forecasted results. We performed an impairment test as of April 30, 2020 on the long-lived assets of the Brazilian asset group. As a result, we recorded impairment charges of $12 million in our Global Operations segment. We also concluded that we had triggering events related to certain trucks under operating leases, due to declines in expected residual values, and certain other long-lived assets. As a result, we recorded charges of $10 million and $6 million , respectively, in our Truck segment. It is reasonably possible that within the next twelve months, we could recognize additional impairment charges for certain trucks under operating leases where Navistar is a lessor, which could be material, if we experience continued declines in excess of our forecasted expected residual values, as a result of the COVID-19 pandemic, the demand for used trucks or a change in the mix of sales through various market channels. During 2019, we identified a triggering event related to continued economic weakness in Brazil and the initiation of strategic cost reduction actions in the Brazilian asset group, which is included in the Global Operations segment. As a result, we estimated the recoverable amount of the asset group and determined that the sum of the undiscounted future cash flows exceeds the carrying value and the asset group was not impaired. For more information regarding asset impairment charges see Note 3, Restructuring, Impairments and Divestitures . Included in equipment leased to others are trucks that we produced or acquired to lease to customers as well as equipment that is financed by Bank of Montreal ("BMO") that does not qualify for revenue recognition, as we retained control of the leased property, which are accounted for as operating leases. In the Consolidated Statement of Cash Flows, the related expenditures are reflected as the Purchases of equipment leased to others in the investing section. Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquired business over the amounts assigned to the net assets. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently, if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that the carrying amount is more likely than not higher than the fair value, goodwill is tested for impairment based on a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, thus the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The income approach is based on discounted cash flows which are derived from internal forecasts and economic expectations for each respective reporting unit. An intangible asset determined to have an indefinite useful life is not amortized until its useful life is determined to no longer be indefinite. Indefinite-lived intangible assets are evaluated each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of the indefinite-lived intangible asset with its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Significant judgment is applied when evaluating if an intangible asset has a finite useful life. In addition, for indefinite-lived intangible assets, significant judgment is applied in testing for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, and incorporating general economic and market conditions. Intangible assets subject to amortization are also evaluated for impairment or when indicators of impairment are determined to exist. We test for impairment of intangible assets, subject to amortization, by comparing the sum of the estimated undiscounted future cash flows expected to result from the operation of the asset group and its eventual disposition to the carrying value. If the sum of the undiscounted future cash flows is less than the carrying value, the fair value of the asset group is determined. The amount of impairment is calculated by subtracting the fair value of the asset group from the carrying value of the asset group. Intangible assets, subject to amortization, could become impaired in the future or require additional charges as a result of declines in profitability due to changes in volume, market pricing, cost, manner in which an asset is used, physical condition of an asset, laws and regulations, or the business environment. We amortize the cost of intangible assets over their respective estimated useful lives, generally on a straight-line basis. The ranges for the amortization periods are generally as follows: Years Customer base and relationships 3 - 15 Trademarks 20 Other 3 - 18 Investments in Non-consolidated Affiliates Equity method investments are recorded at original cost and adjusted periodically to recognize (i) our proportionate share of the investees' net income or losses after the date of investment, (ii) additional contributions made and dividends or distributions received, and (iii) impairment losses resulting from adjustments to fair value. We assess the potential impairment of our equity method investments and determine fair value based on valuation methodologies, as appropriate, including the present value of estimated future cash flows, estimates of sales proceeds, and market multiples. If an investment is determined to be impaired and the decline in value is other than temporary, we record an appropriate write-down. Debt Issuance Costs We amortize debt issuance costs, discounts and premiums over the remaining life of the related debt using the effective interest method. The related income or expense is included in Interest expense . We record debt issuance costs, discounts and premiums associated with term debt as a direct deduction from, or addition to, the face amount of the debt. We record debt issuance costs associated with line-of-credit debt as other assets. Pensions and Postretirement Benefits We use actuarial methods and assumptions to account for our pension plans and other postretirement benefit plans. Pension and other postretirement benefits expense includes the actuarially computed cost of benefits earned during the current service period, the interest cost on accrued obligations, the expected return on plan assets, the straight-line amortization of net actuarial gains and losses and plan amendments, and adjustments due to settlements and curtailments. For more information regarding pension plans and other postretirement benefit plans see Note 12, Postretirement Benefits . Engineering and Product Development Costs Engineering and product development costs arise from ongoing costs associated with improving existing products and manufacturing processes and for the introduction of new truck and engine components and products and are expensed as incurred. Advertising Costs Advertising costs are expensed as incurred and are included in SG&A expenses . These costs totaled $17 million , $31 million , and $31 million for the years ended October 31, 2020 , 2019 , and 2018 , respectively. Contingency Accruals We accrue for loss contingencies associated with outstanding litigation for which we have determined it is probable that a loss occurred and the amount of loss can be reasonably estimated. Our asbestos, product liability, environmental, and workers compensation accruals also include estimated future legal fees associated with the loss contingencies, as we believe we can reasonably estimate those costs. In all other instances, legal fees are expensed as incurred. These expenses may be recorded in Costs of products sold, SG&A expenses, or Other expense, net . These estimates are based on our expectations of the scope, length to complete, and complexity of the claims. In the future, additional adjustments may be recorded as the scope, length, or complexity of outstanding litigation changes. Warranty We generally offer one to five -year warranty coverage for our truck, bus, and engine products, as well as our service parts. Terms and conditions vary by product, customer, and country. We accrue warranty related costs under standard warranty terms and for certain claims outside the contractual obligation period that we choose to pay as accommodations to our customers. Our warranty estimates are established using historical information about the nature, frequency, timing, and average cost of warranty claims. Warranty claims are influenced by numerous factors, including new product introductions, technological developments, the competitive environment, the design and manufacturing process, and the complexity and related costs of component parts. We estimate our warranty accrual for our engines and trucks based on engine types and model years. Our warranty accruals take into account the projected ultimate cost-per-unit ("CPU") utilizing historical claims information. The CPU represents the total cash projected to be spent for warranty claims for a particular model year during the warranty period, divided by the number of units sold. The projection of the ultimate CPU is affected by component failure rates, repair costs, and the timing of failures in the product life cycle. Warranty claims inherently have a high amount of variability in timing and severity and can be influenced by external factors. Our warranty estimation process takes into consideration numerous variables that contribute to the precision of the estimate, but also add to the complexity of the model. Including numerous variables also reduces the sensitivity of the model to any one variable. We perform periodic reviews of warranty spend data to allow for timely consideration of the effects on warranty accruals. Initial warranty estimates for new model year products are based on the previous model year product's warranty experience until the new product progresses sufficiently through its life cycle and related claims data becomes mature. Historically, warranty claims experience for launch-year products has been higher compared to the prior model-year engines; however, over time we have been able to refine both the design and manufacturing process to reduce both the volume and the severity of warranty claims. New product launches require a greater use of judgment in developing estimates until historical experience becomes available. We record adjustments to pre-existing warranties for changes in our estimate of warranty costs for products sold in prior fiscal years. Such adjustments typically occur when claims experience deviates from historic and expected trends. Future events and circumstances could materially change these estimates and require additional adjustments to our liability. When we identify cost effective opportunities to address issues in products sold or corrective actions for safety issues, we initiate product recalls or field campaigns. As a result of the uncertainty surrounding the nature and frequency of product recalls and field campaigns, the liability for such actions is generally recorded when we commit to a product recall or field campaign. Each subsequent quarter after a recall or campaign is initiated the recorded liability balance is analyzed, reviewed, and adjusted if necessary to reflect any changes in the anticipated average cost of repair or number of repairs to be completed prospectively. Included in 2020 warranty expense were $23 million of charges related to new campaign issuances as well as changes in estimates of previously issued campaigns, as compared to $27 million and $10 million in 2019 and 2018 , respectively. The charges were primarily recognized as adjustments to pre-existing warranties. As we continue to identify opportunities to improve the design and manufacturing of our engines we may incur additional charges for product recalls and field campaigns to address identified issues. Optional extended warranty contracts can be purchased for periods ranging from one to ten years. Warranty revenues related to extended warranty contracts are amortized to income, over the life of the contract, (a) in 2020 and 2019 in proportion to the costs expected to be incurred in satisfying the obligation under the contract and (b) in 2018 using the straight-line method. Costs under extended warranty contracts are expensed as incurred. We recognize losses on defined pools of extended warranty contracts when the expected costs for a given pool of contracts exceed related unearned revenue. When collection is reasonably assured, we also estimate the amount of warranty claim recoveries to be received from our suppliers and record them in Other current assets and Other noncurrent assets . Recoveries related to specific product recalls, in which a supplier confirms its liability under the recall, are recorded in Trade and other receivables, net . Warranty costs and recoveries are included in Costs of products sold . Although we believe that the estimates and judgments discussed herein are reasonable, actual results could differ and we may be exposed to increases or decreases in our warranty accrual that could be material. Product Warranty Liability The following table presents accrued product warranty and deferred warranty revenue activity: For the Years Ended October 31, (in millions) 2020 2019 2018 Balance at beginning of period $ 510 $ 529 $ 629 Costs accrued and revenues deferred 162 249 211 Adjustments to pre-existing warranties (A) 40 3 (9 ) Payments and revenues recognized (263 ) (283 ) (303 ) Other adjustments (B) — 12 1 Balance at end of period 449 510 529 Less: Current portion 209 233 255 Noncurrent accrued product warranty and deferred warranty revenue $ 240 $ 277 $ 274 ________________________ (A) Adjustments to pre-existing warranties reflect changes in our estimate of warranty costs for products sold in prior fiscal periods. Such adjustments typically occur when claims experience deviates from historic and expected trends. Our warranty liability is generally affected by component failure rates, repair costs, and the timing of failures. Future events and circumstances related to these factors could materially change our estimates and require adjustments to our liability. In addition, new product launches require a greater use of judgment in developing estimates until historical experience becomes available. (B) Other adjustments in 2019 include a $14 million increase in revenues deferred in connection with the adoption of the new revenue standard (as defined below regarding Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 606), partially offset by a $2 million reduction in liability related to the sale of a majority interest in our defense business, Navistar Defense. In 2018 , Other adjustments relates to $1 million currency translation adjustments. In 2020 , we recognized an immaterial net benefit related to extended warranty contracts on our proprietary big-bore engines. In 2019 , we recognized a net benefit of $14 million related to extended warranty contracts on our proprietary big-bore engines, which included a benefit of $13 million related to pre-existing warranties. In 2018 , we recognized a net benefit of $29 million related to extended warranty contracts on our proprietary big-bore engines, which included a benefit of $33 million related to pre-existing warranties. Stock-based Compensation We have various plans that provide for the granting of stock-based compensation to certain employees, directors, and consultants, which is further described in Note 19, Stock-Based Compensation Plans . Shares are issued upon option exercise from Common stock held in treasury . For transactions in which we obtain employee services in exchange for an award of equity instruments, we measure the cost of the services based on the grant date fair value of the award. We recognize the cost over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period (usually the vesting period). Costs related to plans with graded vesting are generally recognized using a straight-line method. Foreign Currency Translation We translate the financial statements of foreign subsidiaries whose local currency is their functional currency to U.S. dollars using period-end exchange rates for assets and liabilities and weighted average exchange rates for each period for revenues and expenses. Differences arising from exchange rate changes are included in the Foreign currency translation adjustment component of AOCL. For foreign subsidiaries whose functional currency is the U.S. dollar, we remeasure non-monetary balance sheet accounts and the related income statement accounts at historical exchange rates.

Such adjustments typically occur when claims experience deviates from historic and expected trends. Our warranty liability is generally affected by component failure rates, repair costs, and the timing of failures. Future events and circumstances related to these factors could materially change our estimates and require adjustments to our liability. In addition, new product launches require a greater use of judgment in developing estimates until historical experience becomes available. (B) Other adjustments in 2019 include a $14 million increase in revenues deferred in connection with the adoption of the new revenue standard (as defined below regarding Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 606), partially offset by a $2 million
