Accounting Policies [Abstract]
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 11, Segment Reporting . Our fiscal year ends on October 31. As such, all references to 2018 , 2017 , and other years contained within this Quarterly Report on Form 10-Q relate to the fiscal year, unless otherwise indicated. Basis of Presentation and Consolidation The accompanying unaudited 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. We prepared the accompanying unaudited consolidated financial statements in accordance with United States ("U.S.") generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and notes required by U.S. GAAP for comprehensive annual financial statements. The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting policies described in our Annual Report on Form 10-K for the year ended October 31, 2017 , which should be read in conjunction with the disclosures therein. In our opinion, these interim consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial condition, results of operations, and cash flows for the periods presented. Operating results for interim periods are not necessarily indicative of annual operating results. 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.
Significant Accounting Policies [Text Block]	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.

Basis of Presentation and Consolidation The accompanying unaudited 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. We prepared the accompanying unaudited consolidated financial statements in accordance with United States ("U.S.") generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and notes required by U.S. GAAP for comprehensive annual financial statements. The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting policies described in our Annual Report on Form 10-K for the year ended October 31, 2017 , which should be read in conjunction with the disclosures therein. In our opinion, these interim consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial condition, results of operations, and cash flows for the periods presented. Operating results for interim periods are not necessarily indicative of annual operating results. 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 $30 million and $49 million and liabilities of $9 million and $13 million as of April 30, 2018 and October 31, 2017 , respectively, including $16 million and $10 million of cash and cash equivalents, at the respective dates, which are not readily available to satisfy claims against our general assets. The creditors of BDP do not have recourse to our general credit. Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include secured assets of $833 million and $869 million as of April 30, 2018 and October 31, 2017 , respectively, and liabilities of $740 million and $754 million as of April 30, 2018 and October 31, 2017 , 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 $361 million and $278 million as of April 30, 2018 and October 31, 2017 , respectively, and corresponding liabilities of $207 million and $194 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 have no 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 have the ability to 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 Volkswagen Truck & Bus GmbH and its subsidiaries and affiliates ("VW T&B") 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 have also entered into development agreements with VW T&B involving certain engine and transmission projects. This development work is being expensed as incurred. For the three and six months ended April 30, 2018 , revenue recognized was approximately $41 million and $81 million , respectively, compared to $27 million and $42 million in the comparable prior year periods. For the three and six months ended April 30, 2018 , expenses incurred were $8 million and $19 million , respectively, compared to $2 million for both the three and six months ended April 30, 2017 , included primarily in Engineering and product development costs on our Consolidated Statements of Operations. Our receivable from VW T&B was $14 million and $13 million as of April 30, 2018 and October 31, 2017 , respectively. Our payable to VW T&B was $22 million and $5 million as of April 30, 2018 and October 31, 2017 , respectively. Inventories Inventories are valued at the lower of cost or net realizable value ("NRV"). Cost is principally determined using the first-in, first-out method. Our gross used truck inventory was $206 million at both April 30, 2018 and October 31, 2017 , offset by reserves of $63 million and $110 million , respectively. 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 the activity in our used truck reserve: Six Months Ended April 30, (in millions) 2018 2017 Balance at beginning of period $ 110 $ 208 Additions charged to expense (A) 22 88 Deductions/Other adjustments (B) (69 ) (80 ) Balance at end of period $ 63 $ 216 _________________________ (A) Additions charged to expense reflect the increase of the reserve for inventory on hand. During the second quarter of 2017, we implemented a shift in market mix to include an increase in volume to certain export markets, which had a lower price point as compared to sales through our domestic channels, and to lower domestic pricing to enable higher sales velocity. In the second quarter of 2017, we recorded a charge of $60 million in Costs of Products Sold in our Consolidated Statements of Operations . (B) Deductions/Other adjustments reflect reductions of the reserve related to the sale of units and our currency translation adjustments. 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 capital lease obligations at the lower of their fair value or 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. 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 2017, we identified a triggering event related to continued economic weakness in Brazil which resulted in the decline in forecasted results for the Brazilian asset group. The Brazilian asset group 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. Significant adverse changes to our business environment and future cash flows could cause us to record impairment charges in future periods, which could be material. Product Warranty Liability The following table presents accrued product warranty and deferred warranty revenue activity: Six Months Ended April 30, (in millions) 2018 2017 Balance at beginning of period $ 629 $ 818 Costs accrued and revenues deferred 84 87 Currency translation adjustment — (1 ) Adjustments to pre-existing warranties (A) — (10 ) Payments and revenues recognized (162 ) (206 ) Balance at end of period 551 688 Less: Current portion 265 352 Noncurrent accrued product warranty and deferred warranty revenue $ 286 $ 336 _________________________ (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. Extended Warranty Programs The amount of deferred revenue related to extended warranty programs was $250 million and $271 million at April 30, 2018 and October 31, 2017 , respectively. Revenue recognized under our extended warranty programs was $27 million and $56 million for the three and six months ended April 30, 2018 , respectively, and $47 million and $81 million for the three and six months ended April 30, 2017 , respectively. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the periods presented. Significant estimates and assumptions are used for, but are not limited to, pension and other postretirement benefits, allowance for doubtful accounts, income tax contingency accruals and valuation allowances, product warranty accruals, used truck inventory valuations, asbestos and other product liability accruals, asset impairment charges, restructuring charges and litigation-related accruals. Actual results could differ from our estimates. Concentration Risks Our financial condition, results of operations, and cash flows are subject to concentration risks related to our significant unionized workforce. As of April 30, 2018 , approximately 7,400 , or 99% , of our hourly workers and approximately 700 , or 13% , of our salaried workers, are represented by labor unions and are covered by collective bargaining agreements. Our current master collective bargaining agreement with the United Automobile, Aerospace and Agricultural Implement Workers of America ("UAW") will expire in October 2018 and we will be in negotiations with the UAW to enter into a new collective bargaining agreement. Our future operations may be affected by changes in governmental procurement policies, tax policies, budget considerations, changing national defense requirements, and political, regulatory and economic developments in the U.S. and certain foreign countries (primarily Canada, Mexico, and Brazil). Recently Issued Accounting Standards In March 2018, the Financial Accounting Standards Board ("FASB") issued ASU No. 2018-05, "Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118". This ASU updates the income tax accounting in U.S. GAAP to reflect the SEC's interpretive guidance released on December 22, 2017, when the Tax Cuts and Jobs Act (H.R.1) (the "Tax Act") was signed into law. For more information regarding the impact of the Tax Act, see Note 8, Income Taxes. In February 2018, the FASB issued ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220)". This ASU provides guidance on a reclassification from accumulated other comprehensive income ("AOCI") to retained earnings for the effect of the tax rate change resulting from the Tax Act. The amendments eliminate the stranded tax effects resulting from the Tax Act and will improve the usefulness of information reported to financial statement users. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2020. We are currently evaluating the impact of this ASU on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business". This ASU provides a new framework for determining whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This ASU creates an initial screening test (Step 1) that reduces the population of transactions that an entity needs to analyze to determine whether there is an input and substantive processes in the acquisition or disposal (Step 2). Fewer transactions are expected to involve acquiring or selling a business. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2019. Adoption will require a prospective transition. We do not expect the impact of this ASU to have a material effect on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows: Restricted Cash" (Topic 230). This ASU requires that a statement of cash flows explain the change during the period in the total of cash, and cash equivalents, including amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2019. Adoption will require a retrospective transition. We do not expect the impact of this ASU to have a material effect on our consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory” (Topic 740). This ASU update requires entities to recognize the income tax consequences of many intercompany asset transfers at the transaction date. The seller and buyer will immediately recognize the current and deferred income tax consequences of an intercompany transfer of an asset other than inventory. The tax consequences were previously deferred. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2019. Adoption will require a modified retrospective transition. We do not expect the impact of this ASU to have a material effect on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments” (Topic 230). This ASU provides guidance on how entities should classify eight specific cash flow transactions for which diversity in practice exists. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2019. Adoption will require a retrospective transition. We do not expect the impact of this ASU to have a material effect on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments” (Topic 326). This ASU sets forth an expected credit loss model which requires the measurement of expected credit losses for financial instruments based on historical experience, current conditions and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost, and certain off-balance sheet credit exposures. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Adoption will require a modified retrospective transition. This ASU is effective for us in the first quarter of fiscal 2021. We are currently evaluating the impact of this ASU on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases" (Topic 842). This ASU requires lessees to recognize, on the balance sheet, assets and liabilities for the rights and obligations created by leases of greater than twelve months. The accounting by lessors will remain largely unchanged. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2020. Adoption will require a modified retrospective transition with an option to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented. We are currently evaluating the impact of this ASU on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (Topic 606), which supersedes the revenue recognition requirements in ASC 605, “Revenue Recognition." This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU No. 2015-14, which postponed the effective date of ASU No. 2014-09 to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted on the original effective date for fiscal years beginning after December 15, 2016. We continue to evaluate the requirements of the standard and its application to our business. We are analyzing the ASU’s impact on our portfolio of customer contracts which may result in a change in the timing or the amount of revenue recognized in comparison with current guidance. We are also evaluating enhanced disclosure requirements and identifying and implementing appropriate changes to our business processes, systems and internal control framework to support recognition and disclosure under the new guidance. We will adopt this ASU in the first quarter of fiscal 2019 on a modified retrospective basis, with the cumulative effect adjustment recognized into Accumulated deficit as of November 1, 2018.

Restructuring and Related Activities [Abstract]
Restructurings and Impairments	Restructurings and Impairments 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. Restructuring Liability The following tables summarize the activity in the restructuring liability, which excludes pension and other postretirement contractual termination benefits: (in millions) Balance at October 31, 2017 Additions Payments Adjustments Balance at April 30, 2018 Employee termination charges $ 14 $ 1 $ (5 ) $ (3 ) $ 7 Lease vacancy — — — — — Other 1 — — — 1 Restructuring liability $ 15 $ 1 $ (5 ) $ (3 ) $ 8 (in millions) Balance at October 31, 2016 Additions Payments Adjustments Balance at April 30, 2017 Employee termination charges $ 5 $ 8 $ (3 ) $ (1 ) $ 9 Lease vacancy 1 — (1 ) — — Other 1 — — — 1 Restructuring liability $ 7 $ 8 $ (4 ) $ (1 ) $ 10 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) costs for employee and contractor termination and other related benefits, and (iii) charges for pension and other postretirement contractual benefits and curtailments. These charges could be significant. Chatham restructuring activities In the third quarter of 2011, we committed to close our Chatham, Ontario heavy truck plant, which had been idled since June 2009. At that time, we recognized curtailment and contractual termination charges related to postretirement plans. Based on a ruling regarding pension benefits received from the Financial Services Tribunal in Ontario, Canada, in the third quarter of 2014, we recognized an additional charge of $14 million related to the 2011 closure of the Chatham, Ontario plant. Unsuccessful efforts to appeal the ruling in the Ontario court system ended in December 2015. On April 25, 2016, we filed a qualified partial wind-up report for approval by the Financial Services Commission of Ontario ("FSCO"). On January 12, 2017, FSCO issued its approval of the partial wind-up report. On February 27, 2017, we finalized the resolution of statutory severance pay for former employees related to the closure of our Chatham, Ontario plant, resulting in a charge of $6 million in the first quarter of 2017. During the third quarter of 2017, we finalized the Chatham closure agreement. This resulted in the release of $66 million in other post-employment benefit ("OPEB") liabilities. In addition, a pension settlement accounting charge of $23 million was recorded as a result of lump-sum payments made to certain pension plan participants. These charges and benefits were recorded in our Truck segment within Restructuring charges in our Consolidated Statements of Operation s. Global operations employee separation actions In the fourth quarter of 2017, we initiated cost-reduction actions impacting our workforce in Brazil. As a result of these actions, we recognized restructuring charges of $6 million in personnel costs for employee separation and related benefits. In the first six months of 2018, we recognized a benefit of $1 million upon the completion of these separation actions. This benefit was recorded in our Global operations segment within Restructuring charges in our Consolidated Statements of Operations. Melrose Park Facility restructuring activities In the third quarter of 2017, we committed to a plan to cease engine production at our plant in Melrose Park, Illinois (“Melrose Park Facility”) in the third quarter of fiscal year 2018. As a result, in the third quarter of 2017, we recognized charges of $41 million in our Truck segment. The charges include $23 million related to pension and OPEB liabilities and $8 million for severance pay recorded in Restructuring charges in our Consolidated Statements of Operations. We also recorded $10 million of inventory reserves and other related charges in Costs of products sold in our Consolidated Statements of Operations. In the first six months of 2018, we recognized a benefit of $2 million related to the finalized cessation of production agreement. This benefit was recorded in our Truck segment within Restructuring charges in our Consolidated Statements of Operations. Production at the Melrose Park Facility ceased on May 17, 2018. Asset Impairments In the six months ended April 30, 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, a charge of $2 million was recorded in our Truck segment. In February 2018, we completed the sale of the business. In the six months ended April 30, 2018 and 2017 , we concluded that we had triggering events related to certain assets under operating leases. As a result, we recorded charges of $1 million and $7 million , respectively, in our Truck segment. These charges were recorded in Asset impairment charges in our Consolidated Statements of Operations. See Note 9, Fair Value Measurements , for information on the valuation of impaired operating leases and other assets.

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 $2.3 billion and $2.2 billion as of April 30, 2018 and October 31, 2017 , respectively. Included in total assets of our Financial Services operations were finance receivables of $1.9 billion and $1.8 billion as of April 30, 2018 and October 31, 2017 , 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. Our Finance receivables, net in our Consolidated Balance Sheets consist of the following: (in millions) April 30, 2018 October 31, 2017 Retail portfolio $ 674 $ 559 Wholesale portfolio 1,246 1,246 Total finance receivables 1,920 1,805 Less: Allowance for doubtful accounts 22 20 Total finance receivables, net 1,898 1,785 Less: Current portion, net (A) 1,656 1,565 Noncurrent portion, net $ 242 $ 220 _________________________ (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. 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 April 30, 2018 and October 31, 2017 , 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 owner 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 $805 million and $797 million as of April 30, 2018 and October 31, 2017 , respectively. Other finance receivables related to secured transactions that do not qualify for sale accounting treatment were $238 million and $163 million as of April 30, 2018 and October 31, 2017 , 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.

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. In connection with the retiring of our 8.25% Senior Notes, we also commenced a cash tender offer ("Tender Offer"), which resulted in the purchase of $1,051 million aggregate principal amount, or 72.50% of the total outstanding 8.25% Senior Notes at a purchase price of $1,003.80 per $1,000 principal amount, plus accrued and unpaid interest. The proceeds from the 6.625% Senior Notes offering were used to repurchase a portion of our previously existing 8.25% Senior Notes under the Tender Offer, 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. 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 Senior Notes, included in Other expense (income), net on our Consolidated Statement of Operations. Senior Secured Term Loan Credit Agreement On November 6, 2017, we signed a definitive credit agreement relating to a seven-year senior secured term loan credit facility in an aggregate principal amount of $1.6 billion ("Term Loan Credit Agreement"), guaranteed by Navistar International Corporation and twelve of its subsidiaries. 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 term loan ("Term Loan"), to redeem the remaining portion of the previously outstanding 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. The remainder of the proceeds of the Term Loan Credit Agreement will be used for ongoing working capital purposes and general corporate purposes. 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 (income), net on our Consolidated Statement of Operations. Tax Exempt Bond Amendments On November 6, 2017, the Company 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 Recovery Zone Facility Revenue Bonds (the "Tax Exempt Bonds"), including to permit the Company to incur secured debt of 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 previously existing senior secured Term Loan and the Term Loan Credit Agreement. Financial Services Operations In May 2016, NFC amended and extended its 2011 bank credit facility which was originally due in December 2016. The 2016 amendment extended the maturity date to June 2018 and initially reduced the revolving portion of the facility from $500 million to $400 million . In December 2016, and in accordance with the amendment, the revolving portion of the facility was reduced to a maximum of $275 million , the term loan portion of the facility was paid down to $82 million , and the quarterly principal payments were reduced from $9 million to $2 million . In September 2017, the revolving portion of the bank credit facility was amended and extended to a maturity date of September 2021, with the facility maximum reduced from $275 million to $269 million effective in June 2018. The amendment allowed NFC to increase revolving or term loan commitments, subject to obtaining commitments from existing or new lenders to provide additional or increased revolving commitments and/or additional term loans, to permit a maximum total facility size of $700 million after giving effect to any such increase and without taking into account the non-extended loans and commitments. On June 1, 2018, in accordance with the terms of the amended bank credit facility, the term loan portion was paid in full. In December 2017, the maturity date of our 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 . The VFN facility is secured by assets of the wholesale note owner trust. In January 2018, the maturity date of our $100 million Truck Retail Accounts Corporation ("TRAC") funding facility was extended from April 2018 to January 2019. Borrowings under this facility are secured by eligible retail accounts receivable.

Postretirement Benefits

Postretirement Benefits	6 Months Ended

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. 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. For the three and six months ended April 30, 2018 , we contributed $32 million and $53 million , respectively, and for the three and six months ended April 30, 2017 , we contributed $24 million and $46 million , respectively, to our pension plans to meet regulatory funding requirements. We expect to contribute approximately $81 million to our pension plans during the remainder of 2018 . We primarily fund OPEB obligations, such as retiree medical, in accordance with the 1993 Settlement Agreement (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. Contributions for the three and six months ended April 30, 2018 , and 2017 , as well as anticipated contributions for the remainder of 2018 , are not material. 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 three and six months ended April 30, 2018 and 2017 is comprised of the following: Three Months Ended April 30, Six Months Ended April 30, Pension Benefits Health and Life Pension Benefits Health and Life (in millions) 2018 2017 2018 2017 2018 2017 2018 2017 Service cost for benefits earned during the period $ 2 $ 2 $ 1 $ 2 $ 4 $ 4 $ 2 $ 3 Interest on obligation 27 26 11 12 54 53 22 24 Amortization of cumulative loss 27 30 2 5 53 59 4 11 Settlements — — — — 9 — — — Contractual termination benefits — — — — — 1 — — Premiums on pension insurance — 4 — — 2 8 — — Expected return on assets (41 ) (39 ) (6 ) (6 ) (81 ) (79 ) (12 ) (12 ) Net periodic benefit expense $ 15 $ 23 $ 8 $ 13 $ 41 $ 46 $ 16 $ 26 In the six months ended April 30, 2018 , we purchased a group annuity contract for certain retired pension plan participants resulting in a plan remeasurement. As a result, a net actuarial loss of $2 million was recognized as a component of Accumulated other comprehensive loss and a pension settlement accounting expense of $9 million was recognized in SG&A expenses in our Consolidated Statements of Operations . In April 2016, we filed a qualified partial wind-up report for approval by FSCO related to the 2011 closure of our Chatham, Ontario plant. FSCO provided formal approval in January 2017. As a result of an ongoing administration review ordered in conjunction with the partial wind-up, we recognized $1 million of contractual termination charges in the first quarter of 2017. 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. We deposit the matching contribution annually. 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 $11 million and $18 million in the three and six months ended April 30, 2018 , respectively, and $9 million and $16 million in the three and six months ended April 30, 2017 , 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. We have recorded no profit sharing accruals based on the operating performance of the entities that are included in the determination of qualifying profits. For more information on pending arbitration regarding the Supplemental Benefit Trust Profit Sharing Plan, see Note 10, Commitments and Contingencies .

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We compute, on a quarterly basis, an estimated annual effective tax rate considering ordinary income and related income tax expense. For all periods presented, U.S. and certain foreign results are excluded from ordinary income due to ordinary losses for which no benefit can be recognized. Ordinary income refers to income (loss) before income tax expense excluding significant unusual or infrequently occurring items. The tax effect of a significant unusual or infrequently occurring item is recorded in the interim period in which the item occurs. Items included in income tax expense in the periods in which they occur include the tax effects of cumulative changes in tax laws or rates, foreign exchange gains and losses, adjustments to uncertain tax positions, and adjustments to our valuation allowance due to changes in judgment regarding the ability to realize deferred tax assets in future years. On December 22, 2017, the Tax Act was signed into U.S. law. The Tax Act reduces the statutory corporate income tax rate from 35% to 21% , effective January 1, 2018. This rate reduction requires us to remeasure our deferred taxes as of the date the Tax Act was enacted. Our U.S. deferred tax assets, net of deferred tax liabilities, were remeasured and reduced by $1.0 billion , entirely offset by a valuation allowance reduction. As a result, the remeasurement of our deferred tax assets, net of deferred tax liabilities, including the valuation allowance, did not impact our income tax expense or net loss. The Tax Act imposes a tax on the mandatory deemed repatriation of earnings of the Company’s foreign subsidiaries and results in a one-time transition tax. We have provisionally determined that any additional foreign earnings included in taxable income due to deemed repatriation and related income taxes will be offset with existing deferred tax assets. The deferred tax impact has a valuation allowance offset, resulting in no impact on our income tax expense or net income. Our estimates related to the deemed repatriation may change as the Company determines the effect of foreign earnings, foreign cash balances and any regulatory guidance. The Tax Act also adds many new provisions, including changes to limits on the deductions for executive compensation and interest expense, a tax on global intangible low‐taxed income (“GILTI”), the base erosion anti‐abuse tax (“BEAT”) and a deduction for foreign derived intangible income (“FDII”). We are still evaluating the impact of these provisions of the Tax Act, which do not apply until our taxable year beginning November 1, 2018. Companies can either account for taxes on GILTI as incurred or recognize deferred taxes when basis differences exist that are expected to affect the amount of the GILTI inclusion upon reversal. The Company is electing to account for taxes on GILTI as incurred. We have not completed our accounting for the income tax effects of the Tax Act. However, we have computed estimates or “provisional” amounts as permitted by the SEC’s Staff Accounting Bulletin No. 118 (“SAB”) issued on December 22, 2017. Under the SAB companies are allowed a measurement period of up to one year from the date of enactment to complete the accounting for the effects of the Tax Act. We will continue to evaluate the Tax Act’s impact, which may change as a result of additional Treasury guidance, federal or state legislative actions, or changes in accounting standards or related interpretations. The Company’s analyses performed to date are sufficient to calculate a reasonable estimate of the impacts of the Tax Act. 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 continue to maintain a valuation allowance 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 our analysis of the relevant facts and circumstances. 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. 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. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. As of April 30, 2018 , the amount of liability for uncertain tax positions was $30 million . The liability at April 30, 2018 has a recorded offsetting tax benefit associated with various issues that total $9 million . If the unrecognized tax benefits are recognized, all would impact our effective tax rate. However, to the extent we continue to maintain a full valuation allowance against certain deferred tax assets, 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. We recognize interest and penalties related to uncertain tax positions as part of income tax expense. For the three and six months ended April 30, 2018 and 2017 , total interest and penalties related to our uncertain tax positions resulted in an income tax expense of less than $1 million for both periods. 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. 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 —We classify as cash equivalents and restricted cash equivalents 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. Marketable Securities —Our marketable securities portfolios are classified as available-for-sale and may include investments in U.S. government and federal agency securities, commercial paper and other investments with an original maturity greater than 90 days. We use quoted prices from active markets to determine fair value. 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. In certain cases, market data is not available and we estimate inputs such as in situations where trading in a particular commodity is not active. Measurements based upon these unobservable inputs are classified within Level 3. 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 10, 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 4, Allowance for Doubtful Accounts, and for more information regarding impaired assets under operating leases, see Note 2, Restructurings and Impairments. Impaired Property, Plant and Equipment —We 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. For more information regarding the impairment of property, plant and equipment, see Note 2, Restructurings and Impairments. The following table presents the financial instruments measured at fair value on a recurring basis: As of April 30, 2018 As of October 31, 2017 (in millions) Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Marketable securities: U.S. government and federal agency securities $ 40 $ — $ — $ 40 $ 370 $ — $ — $ 370 Derivative financial instruments: Commodity forward contracts (A) — 9 — 9 — 3 — 3 Foreign currency contracts (A) — 3 — 3 — 3 — 3 Interest rate caps (B) — 1 — 1 — 1 — 1 Total assets $ 40 $ 13 $ — $ 53 $ 370 $ 7 $ — $ 377 Liabilities Derivative financial instruments: Commodity forward contracts (C) $ — $ — $ — $ — $ — $ 1 $ — $ 1 Foreign currency contracts (C) — 3 — 3 — 1 — 1 Guarantees — — 27 27 — — 21 21 Total liabilities $ — $ 3 $ 27 $ 30 $ — $ 2 $ 21 $ 23 _________________________ (A) The asset value of commodity forward contracts and foreign currency contracts is included in Other current assets in the accompanying Consolidated Balance Sheets . (B) The asset value of interest rate caps is included in Other noncurrent assets in the accompanying Consolidated Balance Sheets. (C) The liability value of commodity forward contracts and foreign currency contracts is included in Other current 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: Three Months Ended April 30, Six Months Ended April 30, (in millions) 2018 2017 2018 2017 Guarantees, at beginning of period $ (25 ) $ (23 ) $ (21 ) $ (23 ) Transfers out of Level 3 — — — — Issuances (3 ) 2 (8 ) 1 Settlements 1 2 2 3 Guarantees, at end of period $ (27 ) $ (19 ) $ (27 ) $ (19 ) 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 retail and wholesale 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 estimated 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 6.75% 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. 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 April 30, 2018 Estimated Fair Value Carrying Value (in millions) Level 1 Level 2 Level 3 Total Assets Retail notes $ — $ — $ 182 $ 182 $ 187 Liabilities Debt: Manufacturing operations Senior Secured Term Loan Credit Agreement, due 2025 — — 1,604 1,604 1,576 6.625% Senior Notes, due 2026 — 1,144 — 1,144 1,082 4.50% Senior Subordinated Convertible Notes, due 2018 (A) 202 — — 202 197 4.75% Senior Subordinated Convertible Notes, due 2019 (A) 423 — — 423 399 Loan Agreement related to 6.75% Tax Exempt Bonds, due 2040 — 239 — 239 220 Financed lease obligations — — 126 126 126 Other — — 26 26 26 Financial Services operations Asset-backed debt issued by consolidated SPEs, at various rates, due serially through 2023 — — 838 838 837 Bank credit facilities, at fixed and variable rates, due dates from 2018 through 2023 — — 671 671 691 Commercial paper, at variable rates, program matures in 2022 87 — — 87 86 Borrowings secured by operating and finance leases, at various rates, due serially through 2024 — — 105 105 107 As of October 31, 2017 Estimated Fair Value Carrying Value (in millions) Level 1 Level 2 Level 3 Total Assets Retail notes $ — $ — $ 153 $ 153 $ 161 Liabilities Debt: Manufacturing operations Senior Secured Term Loan Credit Facility, as Amended, due 2020 — — 1,019 1,019 1,003 8.25% Senior Notes, due 2022 1,450 — — 1,450 1,423 4.50% Senior Subordinated Convertible Notes, due 2018 (A) 208 — — 208 194 4.75% Senior Subordinated Convertible Notes, due 2019 (A) 446 — — 446 394 Loan Agreement related to 6.50% Tax Exempt Bonds, due 2040 — 243 — 243 220 Financed lease obligations — — 130 130 130 Other — — 23 23 39 Financial Services operations Asset-backed debt issued by consolidated SPEs, at various rates, due serially through 2023 — — 851 851 849 Bank credit facilities, at fixed and variable rates, due dates from 2018 through 2023 — — 592 592 616 Commercial paper, at variable rates, program matures in 2022 92 — — 92 92 Borrowings secured by operating and finance leases, at various rates, due serially through 2024 — — 94 94 94 _________________________ (A) The carrying value represents the consolidated financial statement amount of the debt which excludes the allocation of the conversion feature to equity, while the estimated fair value is derived from quoted prices in active markets which include the equity feature.

Commitments and Contingencies

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 U.S. 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 Financial Group and its wholly-owned subsidiary BMO Harris Bank N.A. (together "BMO") is our third-party preferred source of retail customer financing for equipment offered by us and our dealers in the U.S. We refer to this alliance as "Navistar Capital." The Navistar Capital Operating Agreement contains a loss sharing arrangement for certain credit losses. Under the loss sharing arrangement, as amended, we generally reimburse our financing partner for credit losses in excess of the first 10% of the financed value of a contract; for certain leases we reimburse our financing partner for credit losses up to a maximum of the first 9.5% of the financed value of those lease contracts. Our exposure to loss is mitigated because contracts under the Navistar Capital Operating Agreement are secured by the financed equipment. There was $1.4 billion of outstanding loan principal and operating lease payments receivable at both April 30, 2018 and October 31, 2017 , 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 $2.4 billion at April 30, 2018 and October 31, 2017 , respectively. Generally, we do not carry the contracts under the Navistar Capital Operating Agreement on our Consolidated Balance Sheets . However, for certain Navistar Capital financed contracts which we have accounted for as borrowings, we have recognized equipment leased to others of $110 million and $116 million and financed lease obligations of $126 million and $129 million , in our Consolidated Balance Sheets as of April 30, 2018 and October 31, 2017 , respectively. We also have issued a limited number of residual value guarantees, for which losses are generally capped. If substantial risk of loss has not transferred, we account for these arrangements as operating leases and revenue is recognized on a straight-line basis over the term of the lease. If substantial risk of loss 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 April 30, 2018 , the amount of stand-by letters of credit and surety bonds was $119 million . In addition, as of April 30, 2018 , we have $82 million of outstanding purchase commitments and contracts with $22 million of cancellation fees with expiration dates through 2025. We have entered into industrial participation agreements, commonly known as offset agreements, with customers outside of the U.S. to facilitate economic value back to entities within the foreign nations as the result of their procurement of goods and services from us. These commitments may be satisfied by our placement of supply contracts to established companies within the foreign nations, providing capabilities to the foreign nations, or the creation of joint ventures that generate profits and hire nationals from within the foreign nations. In certain cases, penalties could be imposed if we do not meet our industrial participation commitments. As of April 30, 2018, we have outstanding industrial participation agreements totaling $228 million that extend through 2025. Purchase order commitments associated with fulfilling the industrial participation agreements are included in the purchase commitments amount above. 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 $19 million for these and other environmental matters, which are included within Other current liabilities and Other noncurrent liabilities , as of April 30, 2018 . The majority of these accrued liabilities are expected to be paid subsequent to 2019 . Along with other vehicle manufacturers, we have been subject to an increased number of asbestos-related claims in recent years. 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 claims will continue to grow, and that the costs for resolving asbestos related claims 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 Supplemental Benefit Program Committee (the "Committee"), composed of individuals not appointed by NI or NIC. In August 2013, the Committee filed a motion for leave to amend its February 2013 complaint (which sought injunctive relief for the Company to provide certain information to which it was allegedly entitled under the Supplemental Benefit Trust Profit Sharing Plan) and 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 the Company breached the 1993 Settlement Agreement and violated ERISA by failing to properly calculate profit sharing contributions due under the Supplemental Benefit Trust Profit Sharing Plan. The Committee seeks 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 Supplemental Benefit Trust Profit Sharing Plan. In November 2015, the Company and the Committee selected an arbitrator and the discovery process commenced. On August 1, 2016, the parties submitted briefs on issues related to the scope of the arbitration. On June 29, 2017, the arbitrator ruled, among other things, that the arbitration will include Supplemental Benefit Trust Profit Sharing Plan calculations for the years ending October 31, 2001 through October 31, 2014. On May 2, 2018, the Committee submitted to the arbitrator a proposed schedule for the presentation of the issues to be addressed in the arbitration. On May 30, 2018, the Company submitted to the arbitrator a response in opposition to the Committee’s proposal and proposed a different schedule for the presentation of the issues in the arbitration. 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 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, two lawsuits were filed in the U.S. District Court for the Southern District of Ohio relating to postretirement healthcare and life insurance obligations under the 1993 Settlement Agreement. The first lawsuit (the “Committee’s Complaint”) was filed by the Supplemental Benefit Program Committee. The Committee’s Complaint was filed against NIC, NI, NFC and a former affiliate, all of which are parties to the 1993 Settlement Agreement. Since January 1, 2012, the Navistar, Inc. Retiree Health Benefit Trust, created pursuant to the 1993 Settlement Agreement (the “Base Trust”), has received certain Medicare Part D subsidies from the federal Centers for Medicare and Medicaid Services that were made available for prescription drug benefits provided to Medicare-eligible seniors pursuant to the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 and has also received certain Medicare Part D coverage-gap discounts from prescription drug manufacturers that were made available to eligible seniors pursuant to the Patient Protection and Affordable Care Act (collectively, the “Subsidies”). The Committee alleges, among other things, that the defendants breached the 1993 Settlement Agreement since January 1, 2012 by causing the Base Trust to allocate the Subsidies in a manner that improperly decreased the defendants’ contributions to the Base Trust and increased retiree contributions. The Committee seeks damages, attorneys’ fees and costs for all alleged violations of the 1993 Settlement Agreement, including approximately $26 million which the Committee alleges is the eligible retirees’ “fair share” of the Subsidies that were allegedly misappropriated by the defendants from January, 2012 through April, 2015. The second lawsuit was filed 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 allege, among other things, that the Company violated the terms of the Plan, breached a fiduciary duty under the ERISA, and engaged in ERISA-prohibited transactions by improperly using the Plan’s assets (a portion of the Subsidies) for the Company’s benefit. The Committee Members request 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 request 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 defendants filed motions to dismiss each respective complaint on January 10, 2017. On May 10, 2017, the court dismissed the Committee's Complaint with prejudice, stating that the Committee lacked standing to bring its claims. With respect to the Committee Members’ Complaint, the court declined to dismiss the complaint, but ordered the parties to conduct discovery regarding whether the Committee Members’ Complaint was barred by the applicable statute of limitations and to file a motion for summary judgment thereafter on that issue of timeliness. The defendants filed their motion for summary judgment on September 21, 2017, the Committee Members’ filed their opposition on November 2, 2017, and the defendants filed their reply on November 22, 2017. The motion for summary judgment is pending before the court. On April 6, 2017, a motion was filed in the U.S. District Court for the Southern District of Ohio relating to postretirement healthcare and life insurance obligations under the 1993 Settlement Agreement. The motion was filed by the current "Other Member" of the Health Benefit Program Committee ("HBPC"). The HBPC is provided for in the 1993 Settlement Agreement and the HBPC currently consists of the Other Member, three members appointed by the Company ("Company Members"), and two members appointed by the UAW. NI and the Company Members are named as defendants in the motion. The motion alleges that NI and the Company Members impermissibly interfered with the Other Member's ability to discharge his rights and duties relating to eligibility for Plan benefits for an unknown number of non-represented employees and retirees. He requested that the court (a) find that all prior Plan eligibility determinations made by NI and the HBPC are invalid to the extent they were not based on eligibility criteria in a plan which pre-dated the Plan; and (b) find all employees or retirees who were improperly denied Plan benefits based on the application of incorrect eligibility criteria, to retroactively enroll them in the Plan, and to reimburse those retirees for costs they incurred as a result of the prior improper determinations of Plan eligibility. He estimates 1,000 non-represented employees or retirees were wrongfully denied Plan benefits. He also requested that the court direct him to oversee NI's compliance with the requested relief order. The defendants filed their response to the motion on May 11, 2017 and the Other Member filed his reply on May 17, 2017. The court overruled the Other Member's motion on October 20, 2017, and the time period for filing an appeal has lapsed. 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. 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 April 30, 2018 ), which is not due and final 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 connection with the FATMA Notice, IIAA presented a motion to the district attorney of the State of Santa Catarina (the “SC District Attorney”) to set forth its defenses and correct inaccuracies in the FATMA Notice in August 2017. In September 2017, the SC District Attorney informed IIAA that it intended to present a Consent Agreement to all of the companies that sent waste to Natureza to determine the allocation of the liability for generating the waste which led to the contamination of the Natureza Facility. IIAA then filed a motion requesting that the SC District Attorney consider certain facts and circumstances prior to presenting the Consent Agreement. In January 2018, the SC District Attorney, local and state authorities, Selamix, IIAA and the 14 other companies that are alleged to have significantly contributed to the contamination met to discuss the matter. Selamix then presented three proposals for conducting a preliminary environmental assessment in the area to determine the allocation of liability among the companies. 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 all of the companies after the study is completed. The SC District Attorney agreed to suspend further inquiry into the matter until Selamix’s study has been completed. The other companies involved in the matter have expressed an interest in having an independent environmental study conducted. The SC District Attorney has indicated that it may consider requiring an independent environmental study after Selamix’s environmental study is completed. IIAA continues to dispute the allegations in the FATMA Notice and intends to continue to vigorously defend itself. Currently, no demands or offers are outstanding. 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 approximately less than US $1 million at April 30, 2018 ). In November 2014, IIAA extended a settlement offer. The parties remained in discussions and IIAA’s settlement offer 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 São 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 has made all necessary investigations and has taken remedial measures to address the contamination and that Companhia Ambiental do Estado de São Paulo (CETESB), the environmental agency of São Paulo State, has agreed to the remedial measures taken by IIAA. On June 20, 2017, IIAA presented a petition requesting a 90 day suspension of the lawsuit. IIAA has since held and is currently engaged in discussions with the District Attorney regarding settlement of this matter. The District Attorney agreed to an initial suspension on June 30, 2017. The District Attorney also agreed with a further suspension for an additional 90 days. The court granted the request to stay the proceeding for 90 days, which began on March 9, 2018. A new district attorney (the “New District Attorney”) assumed responsibility for the case in February 2018. The New District Attorney 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. Currently, IIAA is in the process of scheduling a meeting with the New District Attorney’s technical experts. Settlement discussions between IIAA and the New District Attorney are on hold pending the further suspensions. There are no current demands or offers outstanding. MaxxForce Engine EGR Warranty Litigation On June 24, 2014, N&C Transportation Ltd. 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 Canada (together with the N&C Action, the "Canadian Actions"). From June 13-17, 2016, the court conducted a certification hearing in the N&C Action. On November 16, 2016, the court 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. The court in the N&C Action denied certification to persons who operated but did not buy the trucks in question. On November 2, 2017, NIC, NI, Navistar Canada Inc. and Harbour International Trucks filed a notice of appeal. On December 8, 2017, the plaintiff filed a notice of cross-appeal. Both the appeal and cross-appeal were heard by the British Columbia Court of Appeal on February 9, 2018. On June 5, 2017, a hearing was held in the Quebec putative class action lawsuit captioned 4037308 Canada Inc. v. Navistar Canada Inc., NI, and NIC. At that hearing, the court ruled on certain motions regarding evidence related to certification but deferred a ruling on plaintiff’s proposed amendment to narrow the proposed class to Quebec-only purchasers and lessees of model year 2010-13 vehicles containing MaxxForce 11, 13, and 15 liter engines. On November 23, 2017, we filed a motion to stay the Quebec case until the British Columbia Court of Appeal rules on the certification order in the N&C Action. The stay motion was filed on November 23, 2017 and was granted on December 7, 2017. In the Manitoba putative class action lawsuit captioned Vern Brown v. Navistar International Corporation and Navistar Canada, Inc., a case management conference was held on November 17, 2017. Following the conference, the Manitoba court entered an order setting a due date of May 31, 2018, for our application to stay the Manitoba proceedings pending resolution of the N&C Action appeal. The court also set a schedule for briefing on certification, with a certification hearing to take place the last week of January 2019. There are no certification or other hearings scheduled in any of the other Canadian Actions at this time. 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, including the Northern District of Illinois, the Eastern District of Wisconsin, the Southern District of Florida, the Middle District of Pennsylvania, the Southern District of Texas, the Western District of Kentucky, the District of Minnesota, the Northern District of Alabama, and the District of New Jersey (together with the Par 4 Action, the "U.S. Actions"). Some of the U.S. Actions name both NIC and NI, and allege matters substantially similar to the Canadian Actions. More specifically, 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. On October 3, 2014, NIC and NI filed a motion before the United States Judicial Panel on Multidistrict Litigation (the "MDL Panel") seeking to transfer and consolidate before Judge Joan B. Gottschall of the United States District Court for the Northern District of Illinois all of the then-pending U.S. Actions, as well as certain non-class action MaxxForce Advanced EGR engine lawsuits pending in various federal district courts. On December 17, 2014, Navistar's motion to consolidate the U.S. Actions and certain other non-class action lawsuits was granted. The MDL Panel issued an order consolidating all of the U.S. Actions that were pending on the date of Navistar’s motion before Judge Gottschall in the United States District Court for the Northern District of Illinois (the "MDL Action"). The MDL Panel also consolidated into the MDL Action certain non-class action MaxxForce Advanced EGR engine lawsuits pending in the various federal district courts. Non-class federal lawsuits presenting pre-trial issues similar to the MDL Action continue to be transferred to the MDL Action. Approximately 23 such actions are currently pending. At the request of the various law firms representing the plaintiffs in the MDL Action, on March 5, 2015, Judge Gottschall entered an order in the MDL Action appointing interim lead counsel and interim liaison counsel for the plaintiffs. On May 11, 2015, lead counsel for the plaintiffs filed a First Master Consolidated Class Action Complaint ("Consolidated Complaint"). The parties to the MDL Action exchanged initial disclosures on May 29, 2015. The Company answered the Consolidated Complaint on July 13, 2015. On September 22, 2016, lead counsel for the plaintiffs filed a First Amended Consolidated Class Action Complaint (the “Amended Consolidated Complaint”). The Amended Consolidated Complaint added twenty-five additional named plaintiffs. NI and NIC answered the Amended Consolidated Complaint on October 20, 2016. On May 27, 2016, Judge Gottschall entered a Case Management Order setting a July 13, 2017 date for plaintiffs' class certification motion. On November 30, 2016, the court entered an order referring discovery matters to a magistrate judge for supervision. Pursuant to the magistrate’s order, the parties jointly filed a new proposed case management order on January 25, 2017, which extended the fact discovery deadline to November 22, 2017. On January 31, 2017, the parties filed a joint motion with Judge Gottschall requesting adjustment of the class action briefing schedule to April 24, 2018. On February 2, 2017, Judge Gottschall granted the parties' motion extending the deadline to complete the class certification briefing to April 24, 2018. On February 6, 2017, the magistrate approved the parties' schedule set forth in the case management order jointly filed on January 25, 2017. In September 2017, the plaintiffs filed a motion to further extend the case deadlines. On October 5, 2017, Judge Gottschall entered an Agreed Order Extending the Discovery Cutoff ordering that fact discovery relevant to class certification be completed by March 13, 2018 and that the class certification briefing be completed by July 31, 2018. On March 5, 2018, Judge Gottschall extended the fact discovery deadline to be completed by May 25, 2018 and ordered that the class certification briefing be completed by October 22, 2018. On October 13, 2017, lead counsel for the plaintiffs filed a Motion for Leave to File a Second Amended Consolidated Class Action Complaint, as well as a Motion for Voluntary Dismissal of Claims without Prejudice relating to 15 previously named plaintiffs. On January 4, 2018, Judge Gottschall granted both motions. On January 9, 2018, the plaintiffs filed a Second Amended Consolidated Class Action Complaint. The Second Amended Consolidated Class Action Complaint removed 15 named plaintiffs and substituted in eight new named plaintiffs. As a result, the total number of named plaintiffs is now 37 and three class action cases were dismissed entirely without prejudice because there were no longer any remaining plaintiffs in those cases. On November 11, 2017, seven plaintiffs (the “Direct Action Plaintiffs”) in the MDL moved for a separate trial and discovery schedule independent of the class action schedule. On January 2, 2018, Judge Gottschall granted in part and denied in part the Direct Action Plaintiffs’ motion, allowing two of the Direct Action Plaintiffs to begin limited discovery on plaintiff-specific issues. The parties submitted competing proposed discovery schedules. In a minute order dated January 26, 2018, Judge Gottschall declined to enter either schedule but ordered the parties to confer on a schedule for prioritizing the plaintiff-specific discovery after the close of fact discovery relevant to class certification issues. There are also non-class action MaxxForce Adv

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, buses, and military vehicles under the International and IC Bus ("IC") brands, and produces engines under our proprietary brand name and parts required to support the military truck lines. This segment sells its products in the U.S., Canada, and Mexico markets, as well as through our export truck business. In an effort to strengthen and maintain our dealer network, this segment occasionally acquires and operates dealer locations for the purpose of transitioning ownership. • 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 original equipment manufacturers (OEMs) in South America. In addition, our Global Operations segment includes the operating results of our joint venture in China with Anhui Jianghuai Automobile Co ("JAC"). • 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 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) attributable to NIC, excluding income tax benefit (expense).

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 all attributable to NIC in our Consolidated Statements of Operations: Three Months Ended April 30, Six Months Ended April 30, (in millions, except per share data) 2018 2017 2018 2017 Numerator: Net income (loss) attributable to Navistar International Corporation common stockholders $ 55 $ (80 ) $ (18 ) $ (142 ) Denominator: Weighted average shares outstanding: Basic 98.8 93.3 98.7 87.5 Effect of dilutive securities 0.7 — — — Diluted 99.5 93.3 98.7 87.5 Net income (loss) per share attributable to Navistar International Corporation Basic $ 0.56 $ (0.86 ) $ (0.18 ) $ (1.62 ) Diluted 0.55 (0.86 ) (0.18 ) (1.62 ) The conversion rate on our 4.5% Senior Subordinated Convertible Notes due 2018 (the "2018 Convertible Notes") is 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 have an anti-dilutive effect when calculating diluted earnings per share when our average stock price is less than $58.40 . The conversion rate on our 4.75% Senior Subordinated Convertible Notes due 2019 (the “2019 Convertible Notes”) is 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 have an anti-dilutive effect when calculating diluted earnings per share when our average stock price is less than $54.07 . 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. In February 2017, we consummated our previously announced strategic alliance with Volkswagen Truck & Bus GmbH ("VW T&B"), which included an equity investment in the Company by VW T&B pursuant to a Stock Purchase Agreement (the "Stock Purchase Agreement"), a License and Supply Framework Agreement and a Procurement JV Framework Agreement. Pursuant to the Stock Purchase Agreement, on February 28, 2017 we issued and VW T&B purchased 16.2 million shares of our common stock for an aggregate purchase price of $256 million at $15.76 per share (a 19.9% stake ( 16.6% on a fully-diluted basis) in the Company), excluding stock issuance costs. For both the six months ended April 30, 2018 and 2017 , 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. Additionally, certain securities have been excluded from the computation of earnings per share, as our average stock price during the period was less than their respective exercise prices. For the six months ended April 30, 2018 and 2017 , the aggregate shares not included were 14.2 million and 14.8 million , respectively. For the three months ended April 30, 2018 , certain securities have been excluded from the computation of earnings per share, as our average stock price during the period was less than their respective exercise prices. For the three months ended April 30, 2018 , the aggregate shares not included were 13.3 million . For the three months ended April 30, 2017 , 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. Additionally, certain securities have been excluded from the computation of earnings per share, as our average stock price during the period was less than their respective exercise prices. For the three months ended April 30, 2017 , the aggregate shares not included were 14.9 million . For both the three and six months ended April 30, 2018 and 2017 , the aggregate shares not included in the computation of earnings per share were primarily comprised of 3.4 million shares related to the 2018 Convertible Notes and 7.6 million shares related to the 2019 Convertible Notes.

Product Warranty Disclosure [Text Block]	Product Warranty Liability The following table presents accrued product warranty and deferred warranty revenue activity: Six Months Ended April 30, (in millions) 2018 2017 Balance at beginning of period $ 629 $ 818 Costs accrued and revenues deferred 84 87 Currency translation adjustment — (1 ) Adjustments to pre-existing warranties (A) — (10 ) Payments and revenues recognized (162 ) (206 ) Balance at end of period 551 688 Less: Current portion 265 352 Noncurrent accrued product warranty and deferred warranty revenue $ 286 $ 336 _________________________ (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. Extended Warranty Programs The amount of deferred revenue related to extended warranty programs was $250 million and $271 million at April 30, 2018 and October 31, 2017 , respectively. Revenue recognized under our extended warranty programs was $27 million and $56 million for the three and six months ended April 30, 2018 , respectively
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited 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. We prepared the accompanying unaudited consolidated financial statements in accordance with United States ("U.S.") generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and notes required by U.S. GAAP for comprehensive annual financial statements. The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting policies described in our Annual Report on Form 10-K for the year ended October 31, 2017 , which should be read in conjunction with the disclosures therein. In our opinion, these interim consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the financial condition, results of operations, and cash flows for the periods presented. Operating results for interim periods are not necessarily indicative of annual operating results.
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 $30 million and $49 million and liabilities of $9 million and $13 million as of April 30, 2018 and October 31, 2017 , respectively, including $16 million and $10 million of cash and cash equivalents, at the respective dates, which are not readily available to satisfy claims against our general assets. The creditors of BDP do not have recourse to our general credit. Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include secured assets of $833 million and $869 million as of April 30, 2018 and October 31, 2017 , respectively, and liabilities of $740 million and $754 million as of April 30, 2018 and October 31, 2017 , 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 $361 million and $278 million as of April 30, 2018 and October 31, 2017 , respectively, and corresponding liabilities of $207 million and $194 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 have no 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 have the ability to 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.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the periods presented. Significant estimates and assumptions are used for, but are not limited to, pension and other postretirement benefits, allowance for doubtful accounts, income tax contingency accruals and valuation allowances, product warranty accruals, used truck inventory valuations, asbestos and other product liability accruals, asset impairment charges, restructuring charges and litigation-related accruals. Actual results could differ from our estimates.
Concentration Risk Disclosure [Text Block]	Concentration Risks Our financial condition, results of operations, and cash flows are subject to concentration risks related to our significant unionized workforce. As of April 30, 2018 , approximately 7,400 , or 99% , of our hourly workers and approximately 700 , or 13% , of our salaried workers, are represented by labor unions and are covered by collective bargaining agreements. Our current master collective bargaining agreement with the United Automobile, Aerospace and Agricultural Implement Workers of America ("UAW") will expire in October 2018 and we will be in negotiations with the UAW to enter into a new collective bargaining agreement. Our future operations may be affected by changes in governmental procurement policies, tax policies, budget considerations, changing national defense requirements, and political, regulatory and economic developments in the U.S. and certain foreign countries (primarily Canada, Mexico, and Brazil).
Inventory, Policy [Policy Text Block]	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.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In March 2018, the Financial Accounting Standards Board ("FASB") issued ASU No. 2018-05, "Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118". This ASU updates the income tax accounting in U.S. GAAP to reflect the SEC's interpretive guidance released on December 22, 2017, when the Tax Cuts and Jobs Act (H.R.1) (the "Tax Act") was signed into law. For more information regarding the impact of the Tax Act, see Note 8, Income Taxes. In February 2018, the FASB issued ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220)". This ASU provides guidance on a reclassification from accumulated other comprehensive income ("AOCI") to retained earnings for the effect of the tax rate change resulting from the Tax Act. The amendments eliminate the stranded tax effects resulting from the Tax Act and will improve the usefulness of information reported to financial statement users. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2020. We are currently evaluating the impact of this ASU on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business". This ASU provides a new framework for determining whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This ASU creates an initial screening test (Step 1) that reduces the population of transactions that an entity needs to analyze to determine whether there is an input and substantive processes in the acquisition or disposal (Step 2). Fewer transactions are expected to involve acquiring or selling a business. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2019. Adoption will require a prospective transition. We do not expect the impact of this ASU to have a material effect on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows: Restricted Cash" (Topic 230). This ASU requires that a statement of cash flows explain the change during the period in the total of cash, and cash equivalents, including amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2019. Adoption will require a retrospective transition. We do not expect the impact of this ASU to have a material effect on our consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory” (Topic 740). This ASU update requires entities to recognize the income tax consequences of many intercompany asset transfers at the transaction date. The seller and buyer will immediately recognize the current and deferred income tax consequences of an intercompany transfer of an asset other than inventory. The tax consequences were previously deferred. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2019. Adoption will require a modified retrospective transition. We do not expect the impact of this ASU to have a material effect on our consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments” (Topic 230). This ASU provides guidance on how entities should classify eight specific cash flow transactions for which diversity in practice exists. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2019. Adoption will require a retrospective transition. We do not expect the impact of this ASU to have a material effect on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments” (Topic 326). This ASU sets forth an expected credit loss model which requires the measurement of expected credit losses for financial instruments based on historical experience, current conditions and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost, and certain off-balance sheet credit exposures. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. Adoption will require a modified retrospective transition. This ASU is effective for us in the first quarter of fiscal 2021. We are currently evaluating the impact of this ASU on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases" (Topic 842). This ASU requires lessees to recognize, on the balance sheet, assets and liabilities for the rights and obligations created by leases of greater than twelve months. The accounting by lessors will remain largely unchanged. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. This ASU is effective for us in the first quarter of fiscal 2020. Adoption will require a modified retrospective transition with an option to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented. We are currently evaluating the impact of this ASU on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (Topic 606), which supersedes the revenue recognition requirements in ASC 605, “Revenue Recognition." This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU No. 2015-14, which postponed the effective date of ASU No. 2014-09 to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted on the original effective date for fiscal years beginning after December 15, 2016. We continue to evaluate the requirements of the standard and its application to our business. We are analyzing the ASU’s impact on our portfolio of customer contracts which may result in a change in the timing or the amount of revenue recognized in comparison with current guidance. We are also evaluating enhanced disclosure requirements and identifying and implementing appropriate changes to our business processes, systems and internal control framework to support recognition and disclosure under the new guidance. We will adopt this ASU in the first quarter of fiscal 2019 on a modified retrospective basis, with the cumulative effect adjustment recognized into Accumulated deficit as of November 1, 2018.

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.

During the second quarter of 2017, we implemented a shift in market mix to include an increase in volume to certain export markets, which had a lower price point as compared to sales through our domestic channels, and to lower domestic pricing to enable higher sales velocity. In the second quarter of 2017, we recorded a charge of $60 million in Costs of Products Sold in our Consolidated Statements of Operations . (B) Deductions/Other adjustments reflect reductions of the reserve related to the sale of units and our currency translation adjustments.
