Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Organization and Description of the Business
	Navistar International Corporation ("NIC"), incorporated under the laws of the State of Delaware in 1993, is a holding company whose principal operating entities are Navistar, Inc. 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 12, Segment Reporting.
	Our fiscal year ends on October 31. As such, all references to 2015 and 2014 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, which include majority-owned dealers ("Dealcors"), 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.
	Certain reclassifications were made to prior period amounts to conform to the 2015 presentation, which relate to the realignment of our reporting segments that became effective during the first quarter of 2015. For more information, see Note 12, Segment Reporting.
	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, 2014, 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 ("BDP") and Blue Diamond Truck ("BDT") joint ventures with Ford. As a result, our Consolidated Balance Sheets include assets of $263 million and $297 million and liabilities of $238 million and $250 million as of April 30, 2015 and October 31, 2014, respectively, from BDP and BDT, including $87 million and $77 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 and BDT do not have recourse to our general credit. On May 29, 2015, we acquired Ford's remaining 25% ownership in BDT. The termination of the BDT joint venture did not have a material impact on our consolidated financial statements.
	Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include secured assets of $1.2 billion and $1.1 billion as of April 30, 2015 and October 31, 2014, respectively, and liabilities of $923 million and $896 million as of April 30, 2015 and October 31, 2014, 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 $213 million and $156 million and
	corresponding liabilities of $92 million and $54 million as of April 30, 2015 and October 31, 2014, respectively, which are related to other secured transactions that do not qualify for sale accounting treatment, and therefore, are treated as borrowings secured by operating and finance leases. Investors that hold securitization debt have a priority claim on the cash flows generated by their respective securitized assets to the extent that the related VIEs are required to make principal and interest payments. Investors in securitizations of these entities have 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.
	Product Warranty Liability
	The following table presents accrued product warranty and deferred warranty revenue activity:
		Six Months Ended April 30,
	(in millions)	2015			2014
	Balance at beginning of period	$	1,197		$	1,349
	Costs accrued and revenues deferred	116			153
	Currency translation adjustment	(5		)	(1		)
	Adjustments to pre-existing warranties(A)	(39		)	94
	Payments and revenues recognized	(210		)	(272		)
	Balance at end of period	1,059			1,323
	Less: Current portion	496			626
	Noncurrent accrued product warranty and deferred warranty revenue	$	563		$	697
	_________________________
	(A)	Adjustments to pre-existing warranties reflect changes in our estimate of warranty costs for products sold in prior 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.
	In the first quarter of 2015, we recognized a benefit for adjustments to pre-existing warranties of $57 million or a benefit of $0.70 per diluted share. In the first quarter of 2014, we recorded adjustments for changes in estimates of $52 million or charges of $0.64 per diluted share. In the second quarter of 2014, we recorded adjustments for changes in estimates of $42 million, or charges of $0.52 per diluted share. The impact of income taxes on the 2015 and 2014 adjustments are not material due to our deferred tax valuation allowances on our U.S. deferred tax assets.
	Extended Warranty Programs
	The amount of deferred revenue related to extended warranty programs was $425 million and $437 million at April 30, 2015 and October 31, 2014, respectively. Revenue recognized under our extended warranty programs was $38 million and $75 million, in the three and six months ended April 30, 2015, respectively, and $33 million and $60 million for the three and six months ended April 30, 2014, 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, asbestos and other product liability accruals, asset impairment 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 concentrations of our union employees. As of April 30, 2015, approximately 6,200, or 73%, of our hourly workers and approximately 300, or 5%, of our salaried workers are represented by labor unions and are covered by collective bargaining agreements. On February 9, 2015, our United Automobile, Aerospace, and Agricultural Implement Workers of America ("UAW") represented employees ratified a new four-year labor agreement that replaced the prior contract that expired October 1, 2014. Our future operations may be affected by changes in governmental procurement policies, budget considerations, changing national defense requirements, and global, political, regulatory and economic developments in the U.S. and certain foreign countries (primarily Canada, Mexico, and Brazil).
	Goodwill and Indefinite-Lived Intangible Assets
	Goodwill represents the excess of the cost of an acquired business over the amounts assigned to the net assets. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently, if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that the carrying amount is more likely than not higher than the fair value, goodwill is tested for impairment based on a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, thus the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess.
	Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The income approach is based on discounted cash flows which are derived from internal forecasts and economic expectations for each respective reporting unit.
	An intangible asset determined to have an indefinite useful life is not amortized until its useful life is determined to no longer be indefinite. Indefinite-lived intangible assets are evaluated each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of the indefinite-lived intangible asset with its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
	Significant judgment is applied when evaluating if an intangible asset has a finite useful life. In addition, for indefinite-lived intangible assets, significant judgment is applied in testing for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, and incorporating general economic and market conditions.
	During the second quarter of 2014, the economic downturn in Brazil resulted in the continued decline in actual and forecasted results for the Brazilian engine reporting unit with goodwill of $142 million and an indefinite-lived intangible asset, trademark, of $43 million. As a result, we performed an impairment analysis in the second quarter of 2014 utilizing the income approach, based on discounted cash flows, which are derived from internal forecasts and economic expectations. It was determined that the carrying value of the Brazilian engine reporting unit, including goodwill, exceeded its fair value. As a result we compared the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. A decrease in the enterprise value of the reporting unit coupled with appreciation in the value of certain tangible assets, which are not recognized for accounting purposes, resulted in the determination that the entire $142 million of goodwill was impaired. In addition, we determined that the related trademark was impaired and recognized an impairment charge of $7 million. The non-cash impairment charges were included in Asset impairment charges in the Company's Consolidated Statements of Operations. The Brazilian engine reporting unit is included in the Global Operations segment.
	Recently Adopted Accounting Standards
	In the six months ended April 30, 2015, the Company has not adopted any new accounting guidance that has had a material impact on our consolidated financial statements.
	Recently Issued Accounting Standards
	In May 2014, the Financial Accounting Standards Board ("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. The 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. This new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. Our effective date is November 1, 2017. On April 29, 2015 the FASB issued an exposure draft of a proposed ASU that would delay by one year the effective date of ASU 2014-09 and allow early adoption as of the original effective date. The changes to the effective date and early adoption are still subject to final approval. We are currently evaluating the impact and method of adoption of this ASU on our consolidated financial statements.

	North American Manufacturing Restructuring Activities
	We continue to focus on improving our core North American Truck and Parts businesses. We continue to evaluate our portfolio of assets, with the purpose of closing or divesting non-core/non-strategic businesses, and identifying opportunities to restructure our business and rationalize our Manufacturing operations in an effort to optimize our cost structure. The Company is currently evaluating its portfolio of assets to validate their strategic and financial fit. To allow us to increase our focus on our North America core businesses, we are evaluating product lines, businesses, and engineering programs that fall outside of our core businesses. We are using a Return-On-Invested-Capital ("ROIC") methodology, combined with an assessment of the strategic fit to our core businesses, to identify areas that are not performing to our expectations. For those areas, we are evaluating whether to fix, divest, or close. These actions 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, the Company committed to close its Chatham, Ontario heavy truck plant, which had been idled since June 2009. Potential additional charges in future periods could range from $0 million to $60 million, primarily related to pension, postretirement costs and termination benefits, which are subject to employee negotiation, acceptance rates and the resolution of disputes related thereto.
	Foundry Facilities
	In December 2014, we announced the closure of our Indianapolis, Indiana foundry facility, and on April 30, 2015, we sold our Waukesha, Wisconsin foundry operations. As a result of these actions, the Truck segment recognized charges of $13 million and $12 million in the first and second quarter of 2015, respectively, for the acceleration of depreciation of certain assets related to the foundry facilities. These charges are reported within Costs of products sold in the Company's Consolidated Statements of Operations. We expect to incur the remaining accelerated depreciation charges in the third quarter of 2015.
	Cost-Reductions and Other Strategic Initiatives
	From time to time, we have announced, and we may continue to announce, actions to control spending across the Company with targeted reductions of certain costs. We are focused on continued reductions in discretionary spending, including reductions resulting from efficiencies, and prioritizing or eliminating certain programs or projects.
	In the second quarter of 2014, the Company initiated new cost-reduction actions, including an enterprise-wide reduction-in-force. As a result of these actions, the Company recognized restructuring charges of $8 million in personnel costs for employee termination and related benefits, the majority of which was paid during 2014. The Company expects the remaining restructuring charges will be paid throughout 2015.
	Asset Impairments
	The following table reconciles our impairment charges in our Consolidated Statements of Operations
		Three Months Ended April 30,				Six Months Ended April 30,

	Other asset impairment charges related to continuing operations	1		2		8			20
	Total asset impairment charges	$	1	$	151	$	8		$	169
	In the first quarter of 2015, the Company concluded it had a triggering event related to certain operating leases. As a result, the Truck segment recorded $7 million of asset impairment charges, which are recognized in Asset impairment charges in the Company's Consolidated Statements of Operations.
	In the second quarter of 2014, we recognized a total non-cash charge of $149 million for the impairment of certain intangible assets of our Brazilian engine reporting unit. As a result of the economic downturn in Brazil causing declines in actual and forecasted results, we tested the goodwill and indefinite-lived intangible asset of our Brazilian engine reporting unit for potential impairment. As a result, we determined that the entire $142 million balance of goodwill and $7 million of trademarks were impaired. For more information, see Note 1, Summary of Significant Accounting Policies.
	In the first quarter of 2014, the Company concluded it had a triggering event related to potential sales of assets requiring assessment of impairment for certain intangible and long-lived assets in the Truck segment. As a result, certain amortizing intangible assets and long-lived assets were determined to be fully impaired, resulting in an impairment charge of $19 million that was recognized in the six months ended April 30, 2014 in Asset impairment charges in the Company's Consolidated Statements of Operations.

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 $2.6 billion as of both April 30, 2015 and October 31, 2014. Included in total assets of our Financial Services operations are finance receivables of $2.2 billion and $2.0 billion as of April 30, 2015 and October 31, 2014, respectively. We have two portfolio segments of finance receivables based on the type of financing inherent to each portfolio. The retail portfolio segment represents loans or leases to end-users for the purchase or lease of vehicles. The wholesale portfolio segment represents loans to dealers to finance their inventory.
	Our Finance receivables, net consist of the following:
	(in millions)	April 30, 2015			October 31, 2014
	Retail portfolio	$	667		$	726
	Wholesale portfolio	1,515			1,339

	Less: Allowance for doubtful accounts	28			27
	Total finance receivables, net	2,154			2,038
	Less: Current portion, net(A)	1,929			1,758
	Noncurrent portion, net	$	225		$	280
	_________________________
	(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 transfers wholesale notes, retail accounts receivable, retail notes, finance leases, and operating leases through special purpose entities ("SPEs"), which generally are only permitted to purchase these assets, issue asset-backed securities, and make payments on the securities. 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 rates using interest rate swaps and interest rate caps. There were no transfers of finance receivables that qualified for sale accounting treatment as of April 30, 2015 and October 31, 2014, 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 retail note owner trusts or wholesale note 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 $1.1 billion and $996 million as of April 30, 2015 and October 31, 2014, respectively. Other finance receivables related to secured transactions that do not qualify for sale accounting treatment were $149 million and $93 million as of April 30, 2015 and October 31, 2014, 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.

	(A)	We repossess sold and leased vehicles on defaulted finance receivables and leases, and place them into Inventories. Losses recognized at the time of repossession and charged against the allowance for doubtful accounts were both less than $1 million, for the three and six months ended April 30, 2015, as well as for the three and six months ended April 30, 2014.
	(B) Amounts include currency translation.
	The accrual of interest income is discontinued on certain impaired finance receivables. Impaired finance receivables include accounts with specific loss reserves and certain accounts that are on non-accrual status. In certain cases, we continue to collect payments on our impaired finance receivables.

	3.00% Senior Subordinated Convertible Notes
	In October 2009, we completed the sale of $570 million aggregate principal amount of 3.00% senior subordinated convertible notes ("2014 Convertible Notes"), including over-allotment options. The 2014 Convertible Notes were senior subordinated unsecured obligations of the Company.
	In connection with the sale of the 2014 Convertible Notes, the Company purchased call options for $125 million. The call options covered 11,337,870 shares of common stock, subject to adjustments, at an exercise price of $50.27. The call options were intended to minimize share dilution associated with the 2014 Convertible Notes. In addition, in connection with the sale of the 2014 Convertible Notes, the Company also entered into separate warrant transactions whereby, the Company sold warrants for $87 million to sell in the aggregate 11,337,870 shares of common stock, subject to adjustments, at an exercise price of $60.14 per share of common stock.
	During the second quarter of 2014, the Company used proceeds from the private issuance of $411 million of 4.75% senior subordinated convertible notes due April 2019 ("2019 Convertible Notes"), as well as cash on-hand, to repurchase $404 million of notional amount of the 2014 Convertible Notes. The Company recorded a charge of $11 million related to the repurchase which was recognized in Other expense (income), net. In conjunction with the repurchases of the 2014 Convertible Notes, call options representing 8,026,456 shares expired or were unwound by the Company and warrants representing 6,523,319 shares were unwound by the Company. On October 15, 2014, upon maturity, the 2014 Convertible Notes were paid in full and the purchased call options expired worthless.
	During the first quarter of 2015, warrants representing 1,939,376 shares were unwound by the Company, and the remaining 2,875,175 warrants expired worthless on April 10, 2015.

	Asset-backed Debt
	In January 2015, the maturity date of the $500 million variable funding notes ("VFN") facility was extended from March 2015 to January 2016.
	In November 2014, NFC completed the sale of $250 million of two-year investor notes secured by assets of the wholesale note owner trust. Proceeds were used, in part, to replace the $200 million of investor notes that matured in January 2015. Also in November 2014, the wholesale note owner trust was amended to reduce customer concentration restrictions.
	Bank Revolvers and Commercial Paper
	In January 2015, NFC paid $125 million in cash dividends to Navistar, Inc. Dividends and certain affiliate loans are subject to the restricted payment covenants set forth in the NFC bank credit facility.
	Effective December 2014, our Mexican financial services operation entered into a new two-year commercial paper program for up to P$1.8 billion (the equivalent of approximately US $118 million at April 30, 2015). This program replaces the existing program that was to mature in August 2015.

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, 2015, we contributed $32 million and $62 million, respectively, and for the three and six months ended April 30, 2014, we contributed $36 million and $65 million, respectively, to our pension plans to meet regulatory funding requirements. In August 2014, the Highway and Transportation Funding Act of 2014 ("HATFA"), including extension of pension funding interest rate relief, was signed into law. As a result, we lowered our funding expectations. We currently anticipate additional contributions of $51 million to our pension plans during the remainder of 2015.
	We primarily fund other post-employment benefit ("OPEB") obligations, such as retiree medical, in accordance with a 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 the Company's then applicable retiree health care and life insurance benefits. Contributions for the six months ended April 30, 2015 and 2014, as well as anticipated contributions for the remainder of 2015, are not material.
	Components of Net Periodic Benefit Expense
	Net postretirement benefits expense included in our Consolidated Statements of Operations is comprised of the following:

	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. The Company deposits 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 $8 million and $17 million in the three and six months ended April 30, 2015, respectively, and $7 million and $15 million for the three and six months ended April 30, 2014, 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 the Company's consolidated financial statements.
	The Company's contingent profit sharing obligations under a certain Supplemental Benefits Trust Profit Sharing Plan ("Supplemental Benefit 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, see Note 11, Commitments and Contingencies, for a discussion of pending arbitration regarding the Supplemental Benefit Profit Sharing Plan.

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 it occurs. Items included in income tax expense in the periods in which they occur include the tax effects of material restructurings, impairments, cumulative effect of 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.
	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 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. 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, 2015, the amount of liability for uncertain tax positions was $42 million. The liability at April 30, 2015 of $42 million has a recorded offsetting tax benefit associated with various issues that total to $14 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, 2015, total interest and penalties related to our uncertain tax positions resulted in an income tax expense of less than $1 million in each period.
	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 highly liquid investments, with an original maturity of 90 days or less, including U.S. Treasury bills, federal agency securities, and commercial paper, as cash equivalents. 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 primarily include investments in U.S. government securities and commercial paper 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. For more information regarding derivatives, see Note 10, Financial Instruments and Commodity Contracts.
	Guarantees—We provide certain guarantees of payments and residual values to specific counterparties. Fair value of these guarantees is based upon internally developed models that utilize current market-based assumptions and historical data. We classify these liabilities within Level 3. For more information regarding guarantees, see Note 11, Commitments and Contingencies.

	_________________________
	(A)	Certain impaired finance receivables are measured at fair value on a nonrecurring basis. An impairment charge is recorded for the amount by which the carrying value of the receivables exceeds the fair value of the underlying collateral, net of remarketing costs. Fair values of the underlying collateral are determined by reference to dealer vehicle value publications adjusted for certain market factors.
	In the second quarter of 2014, for the purpose of impairment evaluation the Company measured the implied fair value of the Company's Brazilian engine reporting unit's goodwill and the fair value of an indefinite-lived intangible asset, trademark. The Company's Brazilian engine reporting unit's goodwill was determined to be fully impaired and resulted in a non-cash charge of $142 million. In addition, the related trademark, with a carrying value of $43 million was determined to be impaired and a non-cash charge of $7 million was recognized. The impairment charges were included in Asset impairment charges in the Company's Consolidated Statements of Operations. We utilized the income approach to determine the fair value of these Level 3 assets. For more information, see Note 1, Summary of Significant Accounting Policies.
	In the first quarter of 2014, the Company concluded it had a triggering event related to potential sales of assets requiring assessment of impairment for certain intangible and long-lived assets in the Truck segment. As a result, certain amortizing intangible assets and long-lived assets with a carrying value of $18 million were determined to be fully impaired, resulting in an impairment charge of $18 million, which was included in Asset impairment charges in the Company's Consolidated Statements of Operations. We utilized the market approach to determine the fair values of these Level 2 assets.
	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. The fair values of these financial instruments are classified as Level 1. 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 6.5% 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.

Financial Instruments and Commodity Contracts	6 Months Ended
	Apr. 30, 2015
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments and Commodity Contracts	Financial Instruments and Commodity Contracts
	Derivative Financial Instruments
	We use derivative financial instruments as part of our overall interest rate, foreign currency, and commodity risk management strategies to reduce our interest rate exposure, reduce exchange rate risk for transactional exposures denominated in currencies other than the functional currency, and minimize the effect of commodity price volatility. From time to time, we use foreign currency forward and option contracts to manage the risk of exchange rate movements that would affect the value of our foreign currency cash flows. Foreign currency exchange rate movements create a degree of risk by affecting the value of sales made and costs incurred in currencies other than the functional currency. In addition, we also use commodity forward contracts to manage our exposure to variability in certain commodity prices.
	We generally do not enter into derivative financial instruments for speculative or trading purposes and did not during the three and six months ended April 30, 2015 and 2014. None of our derivatives qualified for hedge accounting treatment during the three and six months ended April 30, 2015 and 2014.
	The majority of our derivative contracts are transacted under International Swaps and Derivatives Association ("ISDA") master agreements. Each agreement permits the net settlement of amounts owed in the event of default or certain other termination events. For derivative financial instruments, we have elected not to offset derivative positions in the balance sheet with the same counterparty under the same agreement. Certain of our derivative contracts contain provisions that require us to provide collateral if certain thresholds are exceeded. Collateral of $1 million was provided at April 30, 2015 and no collateral was provided as of October 31, 2014. Collateral is generally not required to be provided by our counter-parties for derivative contracts. We manage exposure to counter-party credit risk by entering into derivative financial instruments with various major financial institutions that can be expected to fully perform under the terms of such instruments. We do not anticipate nonperformance by any of the counter-parties. Our exposure to credit risk in the event of nonperformance by the counter-parties
	is limited to those assets that have been recorded, but have not yet been received in cash. We had $1 million exposure to the credit risk of others at both April 30, 2015 and October 31, 2014.

	Foreign Currency Contracts
	During 2015 and 2014, we entered into foreign exchange forward and option contracts as economic hedges of anticipated cash flows denominated in Brazilian Reais, Euros, Canadian Dollars, and Mexican Pesos. All contracts were entered into to protect against the risk that the eventual cash flows resulting from certain transactions would be affected by changes in exchange rates between the U.S. Dollar and the respective foreign currency.
	The following table presents the outstanding foreign currency contracts as of April 30, 2015 and October 31, 2014:

	(C) Forward exchange contracts of €1 million expire on the last day of each month from February 2015 through October 2015.
	Commodity Forward Contracts
	During 2015 and 2014, we entered into commodity forward contracts as economic hedges of our exposure to variability in commodity prices for diesel fuel and steel. As of April 30, 2015, we had outstanding diesel fuel contracts with aggregate notional values of $17 million and outstanding steel contracts with aggregate notional values of $11 million. The commodity forward contracts have maturity dates ranging from April 30, 2015 to October 31, 2015. As of October 31, 2014, we had outstanding diesel fuel contracts with aggregate notional values of $24 million and outstanding steel contracts with aggregate notional values of $23 million. All of these contracts were entered into to protect against the risk that the eventual cash flows related to purchases of the commodities will be affected by changes in prices.
	Interest-Rate Contracts
	From time to time, we enter into various interest-rate contracts, interest rate caps, and cross currency swaps. As of April 30, 2015, there were no outstanding cross currency swaps. As of October 31, 2014, the notional amount of our outstanding cross currency swaps was $27 million. We are exposed to interest rate and exchange rate risk as a result of our borrowing activities. The objective of these contracts is to mitigate fluctuations in earnings, cash flows, and fair value of borrowings. Our Mexican financial services operation uses interest rate caps and cross currency swaps to protect against the potential of rising interest rates as required by the terms of its variable-rate asset-backed securities and fluctuations in the value of the peso, as required under Mexican bank credit facilities. As of April 30, 2015 and October 31, 2014, the notional amount of our outstanding interest rate caps was $118 million and $134 million, respectively.

Commitments_and_Contingencies

Commitments and Contingencies	6 Months Ended
	Apr. 30, 2015
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.
	In March 2010, we entered into an operating agreement, as amended, which contains automatic extensions and is subject to early termination provisions, with GE (the "GE Operating Agreement"). Under the terms of the GE Operating Agreement, as amended, GE is our preferred source of retail customer financing for equipment offered by us and our dealers in the U.S. We provide GE with a loss sharing arrangement for certain credit losses. Under the loss sharing arrangement, as amended, we generally reimburse GE for credit losses in excess of the first 10% of the financed value of a contract; for certain leases we reimburse GE for credit losses up to a maximum of the first 9.5% of the financed value of those lease contracts. The Company’s exposure to loss is mitigated because contracts under the GE Operating Agreement are secured by the financed equipment. There were $1.6 billion and $1.5 billion of outstanding loan principal and operating lease payments receivable at April 30, 2015 and October 31, 2014, financed through the GE Operating Agreement and subject to the loss sharing arrangements in the U.S. The related financed values of these outstanding contracts were $2.3 billion at both April 30, 2015 and October 31, 2014. Generally, we do not carry the contracts under the GE Operating Agreement on our Consolidated Balance Sheets. However, for certain GE financed contracts which we have accounted for as borrowings, we have recognized equipment leased to others of $129 million and financed lease obligations of $139 million in our Consolidated Balance Sheets for the period ended April 30, 2015.
	Historically, our losses, representing the entire loss amount, on similar contracts, measured as a percentage of the average balance of the related contracts, ranged from 0.3% to 2.1%. Under limited circumstances NFC retains the right to originate retail customer financings. Based on our historic experience of losses on similar contracts and the nature of the loss sharing arrangement, we do not believe our share of losses related to balances currently outstanding will be material.
	For certain independent dealers’ wholesale inventory financed by third-party banks or finance companies, we provide limited repurchase agreements to the respective financing institution. The amount of losses related to these arrangements has not been material to our Consolidated Statements of Operations or Consolidated Statements of Cash Flows and the value of the guarantees and accruals recorded are not material to our Consolidated Balance Sheets.
	We also have issued limited residual value guarantees in connection with various leases. 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. The amount of losses related to these arrangements has not been material to our Consolidated Statements of Operations or Consolidated Statements of Cash Flows and the value of the guarantees and accruals recorded are not material to our Consolidated Balance Sheets.
	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, 2015, the amount of stand-by letters of credit and surety bonds was $88 million.
	We extend credit commitments to certain truck fleet customers, which allow them to purchase parts and services from participating dealers. The participating dealers receive accelerated payments from us with the result that we carry the receivables and absorb the credit risk related to these customers. As of April 30, 2015, the total credit limit under this program was $11 million of which $7 million was unused.
	In addition, as of April 30, 2015, we have entered into various purchase commitments of $120 million and contracts that have cancellation fees of $33 million with various expiration dates through 2020.
	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.
	Two sites formerly owned by us: (i) Solar Turbines in San Diego, California, and (ii) the Canton Plant in Canton, Illinois; were identified as having soil and groundwater contamination. Two sites in Sao Paulo, Brazil, one at which we are currently operating and one where we formerly operated, were identified as having soil and groundwater contamination. While investigations and cleanup activities continue at these and other sites, we believe that we have adequate accruals to cover costs to complete the cleanup of all sites.
	We have accrued $22 million for these and other environmental matters, which are included within Other current liabilities and Other noncurrent liabilities, as of April 30, 2015. The majority of these accrued liabilities are expected to be paid subsequent to 2015.
	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"), comprised of non-Company individuals. 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 Benefits 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 Benefits Profit Sharing Plan. The Committee seeks damages in excess of $50 million, injunctive relief and reimbursement of attorneys' fees and costs. In October 2013, the Company filed a Motion to Dismiss the Profit Sharing Complaint and to compel the Committee to comply with the dispute resolution procedures set forth in the Supplemental Benefits Profit Sharing Plan. In March 2014, the Court denied the Company's Motion to Dismiss and ruled, among other things, that the Company waived its right to compel the Committee to comply with the dispute resolution provisions set forth in the Supplemental Benefits Profit Sharing Plan. In April 2014, the Company appealed the Court's refusal to compel the Committee to comply with the dispute resolution process to the Court of Appeals for the 6th Circuit. The Company also filed a motion with the Court to stay all proceedings pending the appeal. In May 2014, the Court granted the motion to stay all proceedings, including discovery, pending the appeal. In March 2015, the Court of Appeals vacated the Court's March 2014 denial of the Company's Motion to Dismiss and related ruling and remanded with instructions to order that the Committee's claims in the Profit Sharing Complaint be arbitrated. 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 Profit Sharing Plan.
	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.
	FATMA Notice
	International Indústria de Motores 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 in July 2010 from the State of Santa Catarina Environmental Protection Agency ("FATMA") in Brazil. The notice alleged that Maxion had sent wastes to a facility owned and operated by a company known as Natureza and that soil and groundwater contamination had occurred at the Natureza facility. The notice asserted liability against Maxion and assessed an initial penalty in the amount of R$2 million (the equivalent of less than US$1 million at April 30, 2015), 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. IIAA disputes the allegations in the notice and intends to vigorously defend itself.
	Sao Paulo Groundwater Notice
	In March 2014, IIAA, along with other nearby companies, received from the Sao Paulo 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 seeks certain groundwater investigations and other technical relief and proposes sanctions in the amount of R$3 million (the equivalent of approximately US$1 million at April 30, 2015). In November 2014, IIAA extended a settlement offer and the parties remain in discussions regarding this matter.
	MaxxForce Engine EGR Warranty Litigation
	On June 24, 2014, N&C Transportation Ltd. filed a putative class action lawsuit against NIC, Navistar, Inc., Navistar Canada Inc., and Harbour International Trucks in Canada in the Supreme Court of British Columbia (the "N&C Action").  Subsequently, five additional, similar putative class action lawsuits have been filed in Canada (together with the N&C Action, the "Canadian Actions").
	On July 7, 2014, Par 4 Transport, LLC filed a putative class action lawsuit against Navistar, Inc. in the United States District Court for the Northern District of Illinois (the "Par 4 Action"). Subsequently, similar 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 Southern District of Texas, the District of Minnesota, the Northern District of Alabama, the Western District of Kentucky, and the Middle District of Pennsylvania (together with the Par 4 Action, the "U.S. Actions"). The U.S. Actions contained allegations substantially similar to the Canadian Actions. More specifically, the Canadian Actions and the U.S. Actions (collectively, the "EGR Class Actions") seek to certify one or more classes 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 Navistar, Inc. failed to disclose and/or correct the alleged defect. The EGR Class Actions assert claims based on various theories, including breach 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 Navistar, Inc. 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 U.S. Actions then pending, 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 was granted. The MDL Panel issued an order consolidating all of the U.S. Actions pending on the date the motion was filed before Judge Gottschall in the United States District Court for the Northern District of Illinois. The MDL Panel also consolidated certain non-class action MaxxForce Advanced EGR engine lawsuits pending in the various federal district courts, with the exception of one matter.
	For cases filed after the initial ruling by the MDL Panel, we continue to request that the MDL Panel similarly transfer and consolidate cases involving one or more common questions of fact. To date, eight putative class actions and three non-class cases have been added to the MDL proceeding before Judge Gottschall. On March 5, 2015, Judge Gottschall entered an order in the MDL proceeding, 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. The next status conference is set for July 2015.
	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.
	EPA Notice of Violation
	In February 2012, Navistar, Inc. received a Notice of Violation ("NOV") from the U.S. Environmental Protection Agency ("EPA"). The NOV pertains to approximately 7,600 diesel engines which, according to the EPA, were produced by Navistar, Inc. in 2010 and, therefore, should have met the EPA's 2010 emissions standards. Navistar, Inc. previously provided information to the EPA evidencing its belief that the engines were in fact produced in 2009. The NOV contains the EPA's conclusion that Navistar, Inc.'s alleged production of the engines in 2010 violated the Federal Clean Air Act. The NOV states that the EPA reserves the right to file an administrative complaint or to refer this matter to the U.S. Department of Justice ("DOJ") with a recommendation that a civil complaint be filed in federal district court. In July 2014, the DOJ informed Navistar that the matter had been referred to the DOJ. Navistar and the DOJ are in continuing discussions concerning this matter. If the DOJ ultimately initiates litigation, it is likely that the DOJ will request a significant civil penalty.
	Based on our assessment of the facts underlying the NOV above, we are unable to provide meaningful quantification of how the final resolution of this matter may impact our future consolidated financial condition, results of operations or cash flows.
	CARB Notice of Violation
	In April 2013, Navistar, Inc. received a notice of violation and proposed settlement ("Notice") from the California Air Resources Board ("CARB"). The Notice alleges violations of the California regulations relating to verification of after-treatment devices and proposed civil penalties of approximately $2.5 million, among other proposed settlement terms. Beginning in June 2013, the Company has made settlement offers to CARB and remains in discussions regarding this matter. In October 2014, the parties tentatively agreed to resolve the matter for a penalty payment of $0.3 million and the Company's agreement to conduct certain in-use testing. The parties are in the process of finalizing documents formalizing the settlement.
	Shareholder Litigation
	In March 2013, a putative class action complaint, alleging securities fraud, was filed against us by the Construction Workers Pension Trust Fund - Lake County and Vicinity, on behalf of itself and all other similarly situated purchasers of our common stock between the period of November 3, 2010 and August 1, 2012. A second class action complaint was filed in April 2013 by the Norfolk County Retirement System, individually and on behalf of all other similarly situated purchasers of our common stock between the period of June 9, 2010 and August 1, 2012. A third class action complaint was filed in April 2013 by Jane C. Purnell FBO Purnell Family Trust, on behalf of itself and all other similarly situated purchasers of our common stock between the period of November 3, 2010 and August 1, 2012. Each complaint named us as well as Daniel C. Ustian, our former President and Chief Executive Officer, and Andrew J. Cederoth, our former Executive Vice President and Chief Financial Officer as defendants. These complaints (collectively, the "10b-5 Cases") contain similar factual allegations which include, among other things, that we violated the federal securities laws by knowingly issuing materially false and misleading statements concerning our financial condition and future business prospects and that we misrepresented and omitted material facts in filings with the SEC concerning the timing and likelihood of EPA certification of our EGR technology to meet 2010 EPA emission standards. The plaintiffs in these matters seek compensatory damages and attorneys' fees, among other relief. In May 2013, an order was entered transferring and consolidating all cases before one judge and in July 2013, the Court appointed a lead plaintiff and lead plaintiff's counsel. The lead plaintiff filed a consolidated amended complaint in October 2013. The consolidated amended complaint enlarged the proposed class period to June 9, 2009 through August 1, 2012, and named fourteen additional current and former directors and officers as defendants. In December 2013, we filed a motion to dismiss the consolidated amended complaint. In July 2014, the Court granted the defendants' Motions to Dismiss, denied the lead plaintiff's Motion to Strike as moot, and gave the lead plaintiff leave to file a second consolidated amended complaint. In August, 2014, the plaintiff timely filed a Second Amended Complaint, which narrows the claims in two ways. First, the plaintiff abandoned its claims against the majority of the defendants, asserting claims against only Navistar, Dan Ustian, A.J. Cederoth, Jack Allen, and Eric Tech. The plaintiff also shortened the putative class period by changing the class period commencement date from June 9, 2009 to March 10, 2010. Defendants filed their Motion to Dismiss the Second Amended Complaint in September, 2014 and in October, 2014, the plaintiff filed its opposition to defendants Motion to Dismiss. In November, 2014, defendants filed their reply brief in support of defendants Motion to Dismiss the Second Amended Complaint. Also in November 2014, the plaintiff voluntarily dismissed Eric Tech as a defendant. The Court had set a ruling date on the Motion to Dismiss the Second Amended Complaint for February 17, 2015. On the Court's own motions, the ruling date was initially extended to April 15, 2015 and subsequently extended again to May 13, 2015 and subsequently extended again to June 11, 2015.
	In March 2013, James Gould filed a derivative complaint on behalf of the Company against us and certain of our current and former directors and former officers. The complaint alleges, among other things, that certain of our current and former directors and former officers committed a breach of fiduciary duty, waste of corporate assets and were unjustly enriched in relation to similar factual allegations made in the 10b-5 Cases. The plaintiff in this matter seeks compensatory damages, certain corporate governance reforms, certain injunctive relief, disgorgement of the proceeds of certain defendants' profits from the sale of Company stock, and attorneys' fees, among other relief. On May 3, 2013, the Court entered a Stipulation and Order to Stay Action, staying the case pending further order of the court or entry of an order on the motion to dismiss the consolidated amended complaint in the 10b-5 Cases. On July 31, 2014, after the amended complaint was dismissed, the parties filed a status report, and the court entered an order on August 27, 2014 continuing the stay pending a ruling on defendants' Motion to Dismiss the Second Amended Complaint in the 10b-5 Cases.
	Each of these matters is pending in the United States District Court, Northern District of Illinois.
	In August 2013, Abbie Griffin, filed a derivative complaint in the State of Delaware Court of Chancery, on behalf of the Company and all similarly situated stockholders, against the Company, as the nominal defendant, and certain of our current and former directors and former officers. The complaint alleges, among other things, that certain of our current and former directors and former officers committed a breach of fiduciary duty, in relation to similar factual allegations made in the 10b-5 Cases. The plaintiff in this matter seeks compensatory damages, certain corporate governance reforms, certain injunctive relief, and attorneys' fees, among other relief. On August 29, 2013, the court entered an order staying the case pending resolution of the defendant's Motion to Dismiss the consolidated amended complaint in the 10b-5 Cases. On August 5, 2014, the parties filed a status report with the court requesting that the August 2013 stay order remain in place pending a ruling on defendant's Motion to Dismiss the Second Amended Complaint in the 10b-5 Cases and on November 9, 2014, the court entered an order continuing the stay pending a ruling on defendants’ Motion to Dismiss the Second Amended Complaint in the 10b-5 Cases.
	Based on our assessment of the facts underlying these matters described above, we are unable to provide meaningful quantification of how the final resolution of these matters may impact our future consolidated financial condition, results of operations, or cash flows.
	Brazil Truck Dealer Disputes
	In January 2014, IIAA initiated an arbitration proceeding under the International Chamber of Commerce rules seeking payment for goods sold and unpaid, in the amount of R$64 million, including penalties and interest, from a group of four truck dealers in Brazil. The truck dealers are affiliated with each other, but not with us, and are collectively referred to as Navitrucks. In the proceeding, IIAA also seeks a declaration of fault against Navitrucks related to the termination of the truck dealer agreements between IIAA and Navitrucks. Navitrucks responded in part by submitting counterclaims against IIAA seeking the amount of R$128 million for damages related to alleged unfulfilled promises and injury to Navitrucks’ reputation. In October 2014, Navitrucks amended their counterclaims by increasing the amount of damages. During a preliminary hearing before the arbitral tribunal on March 24, 2015, the parties agreed to submit all of the pending claims between the parties to the exclusive jurisdiction of the arbitral tribunal. The arbitral tribunal will issue a schedule for the arbitration submissions. As of April 30, 2015, the approximate amount of the IIAA claim against Navitrucks is R$71 million (approximately US$24 million as of April 30, 2015), and the approximate amount of the Navitrucks claim against IIAA is R$182 million (approximately US$61 million as of April 30, 2015).
	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.
	In addition, two other truck dealers and a truck fleet owner in Brazil have initiated separate adversarial proceedings against IIAA that may have similar legal and factual issues as the Navitrucks claim. These other claims are not material either individually or in the aggregate.
	Other
	U.S. Securities and Exchange Commission Inquiry
	In June 2012, Navistar received an informal inquiry from the Chicago Office of the Enforcement Division of the SEC seeking a number of categories of documents for the periods dating back to November 1, 2010, relating to various accounting and disclosure issues. We received a formal order of private investigation in July 2012. We have received subsequent subpoenas from the SEC in connection with their inquiry. In December 2014, the SEC filed an application in the United States District Court for the Northern District of Illinois seeking an order compelling the production of certain documents withheld by Navistar from its responses to the administrative subpoenas on the basis of attorney-client privilege and/or work product doctrine. The discovery dispute involves a small number of documents in relation to the number of documents already produced by Navistar. A status hearing on this matter was held on April 2, 2015 and the parties are awaiting a decision from the Court. We continue to cooperate with the SEC in this matter. At this time, we are unable to predict the outcome of this matter or provide meaningful quantification of how the final resolution of this matter may impact our future consolidated financial condition, results of operations or cash flows.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting
	During November 2014, we announced changes in our leadership team and in our organizational and reporting structures. We believe this realignment will guide us into the future and enable us to accelerate our performance as we finish the turnaround. These changes impact how our Chief Operating Decision Maker (“CODM”) assesses the performance of our operating segments and makes decisions about resource allocations. As a result, we identified the following changes within our reportable segments:
	•	The export truck and parts operations, formerly in our Global Operations segment, are now included within the results of our Truck and Parts segments, respectively.
	•	Parts required to support the military truck lines, formerly within our Parts segment, are now included within the results of our Truck segment.
	All prior period segment information has been updated to conform to the 2015 presentation. Other than the changes noted above, there were no material changes to the reportable segments disclosed in our Annual Report on Form 10-K for the year ended October 31, 2014. The change in reportable segments had no effect on the Company's consolidated financial position, results of operations, or cash flows for the periods presented.
	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, along with production of engines under the MaxxForce brand name and parts required to support the military truck lines, in the markets that include sales in the U.S., Canada, Mexico, and within 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, MaxxForce 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 the IIAA (formerly MWM International Industria De Motores Da America Do Sul Ltda. ("MWM")) engine and truck operations in Brazil. The IIAA engine operations produce diesel engines, primarily under contract manufacturing arrangements, as well as under the MWM brand, for sale to 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.
	Corporate contains those items that are not included in our four segments.

	The conversion rate on our 2014 Convertible Notes were 19.891 shares of common stock per $1,000 principal amount of 2014 Convertible Notes, equivalent to an initial conversion price of $50.27 per share of common stock. In connection with the sale of the 2014 Convertible Notes, we sold warrants to various counterparties to purchase shares of our common stock from us at an exercise price of $60.14 per share. The 2014 Convertible Notes and warrants were anti-dilutive when calculating diluted earnings per share when our average stock price is less than $50.27 and $60.14, respectively. During the second quarter of 2014, the Company unwound warrants representing 6.5 million shares associated with the repurchased 2014 Convertible Notes. On October 15, 2014, upon maturity the 2014 Convertible Notes were repaid in full. During the first quarter of 2015, the Company unwound warrants representing 1.9 million shares associated with the 2014 Convertible Notes, and the remaining 2.9 million warrants expired worthless on April 10, 2015.
	The conversion rate on our 4.50% 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 are anti-dilutive when calculating diluted earnings per share when our average stock price is less than $58.40.
	The conversion rate on our 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 are anti-dilutive 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.
	For the three and six months ended April 30, 2015 and 2014, no dilutive securities were included in the computation of diluted loss per share since they would have been anti-dilutive due to the net loss attributable to Navistar International Corporation. Additionally, certain securities have been excluded from the computation of earnings per share, as our average stock price was less than their respective exercise prices. For both the three and six months ended April 30, 2015, the aggregate shares not included were 16.0 million. For the three and six months ended April 30, 2014, the aggregate shares not included were 24.0 million and 27.3 million, respectively.
	For both the three and six months ended April 30, 2015, 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.
	For the three months ended April 30, 2014, the aggregate shares not included in the computation of earnings per share were primarily comprised of 4.8 million shares related to the warrants, 3.3 million shares related to the 2014 Convertible Notes, 3.4 million shares related to the 2018 Convertible Notes, and 7.6 million shares related to the 2019 Convertible Notes.
	For the six months ended April 30, 2014, the aggregate shares not included in the computation of earnings per share were primarily comprised of 8.1 million shares related to the warrants, 7.3 million shares related to the 2014 Convertible Notes, 3.4 million shares related to the 2018 Convertible Notes, and 3.8 million shares related to the 2019 Convertible Notes.

Condensed Consolidating Guarantor and Non-Guarantor [Abstract]
Condensed Consolidating Guarantor and Non-guarantor Financial Information	Consolidating Guarantor and Non-guarantor Financial Information
	The following tables set forth condensed consolidating balance sheets as of April 30, 2015 and October 31, 2014, and condensed consolidating statements of operations and condensed consolidating statements of comprehensive income (loss) for the three and six months ended April 30, 2015 and 2014, and condensed consolidating statements of cash flows for the six months ended April 30, 2015 and 2014.
	The information is presented as a result of Navistar, Inc.’s guarantee, exclusive of its subsidiaries, of NIC’s indebtedness under our 8.25% Senior Notes, due 2021, and obligations under our Loan Agreement related to the 6.5% Tax Exempt Bonds, due 2040. Navistar, Inc. is a direct wholly-owned subsidiary of NIC. None of NIC’s other subsidiaries guarantee any of these notes or bonds. The guarantees are "full and unconditional", as those terms are used in Regulation S-X Rule 3-10, except that the guarantees will be automatically released in certain customary circumstances, such as when the subsidiary is sold or all of the assets of the subsidiary are sold, the capital stock is sold, when the subsidiary is designated as an "unrestricted subsidiary" for purposes of the respective indenture for each of the 8.25% Senior Notes, due 2021, and the 6.5% Tax Exempt Bonds, due 2040, upon liquidation or dissolution of the subsidiary or upon legal or covenant defeasance, or satisfaction and discharge of the notes or bonds. Separate financial statements and other disclosures concerning Navistar, Inc. have not been presented because management believes that such information is not material to investors. Within this disclosure only, "NIC" includes the financial results of the parent company only, with all of its wholly-owned subsidiaries accounted for under the equity method. Likewise, "Navistar, Inc.," for purposes of this disclosure only, includes the consolidated financial results of its wholly-owned subsidiaries accounted for under the equity method and its operating units accounted for on a consolidated basis. "Non-Guarantor Subsidiaries" includes the combined financial results of all other non-guarantor subsidiaries. "Eliminations and Other" includes all eliminations and reclassifications to reconcile to the consolidated financial statements. NIC files a consolidated U.S. federal income tax return that includes Navistar, Inc. and its U.S. subsidiaries. Navistar, Inc. has a tax allocation agreement ("Tax Agreement") with NIC which requires Navistar, Inc. to compute its separate federal income tax liability and remit any resulting tax liability to NIC. Tax benefits that may arise from net operating losses of Navistar, Inc. are not refunded to Navistar, Inc. but may be used to offset future required tax payments under the Tax Agreement. The effect of the Tax Agreement is to allow NIC, the parent company, rather than Navistar, Inc., to utilize current U.S. taxable losses of Navistar, Inc. and all other direct or indirect subsidiaries of NIC.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Apr. 30, 2015
Accounting Policies [Abstract]
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, which include majority-owned dealers ("Dealcors"), 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.
	Certain reclassifications were made to prior period amounts to conform to the 2015 presentation, which relate to the realignment of our reporting segments that became effective during the first quarter of 2015. For more information, see Note 12, Segment Reporting.
	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, 2014, 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 ("BDP") and Blue Diamond Truck ("BDT") joint ventures with Ford. As a result, our Consolidated Balance Sheets include assets of $263 million and $297 million and liabilities of $238 million and $250 million as of April 30, 2015 and October 31, 2014, respectively, from BDP and BDT, including $87 million and $77 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 and BDT do not have recourse to our general credit. On May 29, 2015, we acquired Ford's remaining 25% ownership in BDT. The termination of the BDT joint venture did not have a material impact on our consolidated financial statements.
	Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include secured assets of $1.2 billion and $1.1 billion as of April 30, 2015 and October 31, 2014, respectively, and liabilities of $923 million and $896 million as of April 30, 2015 and October 31, 2014, 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 $213 million and $156 million and
	corresponding liabilities of $92 million and $54 million as of April 30, 2015 and October 31, 2014, respectively, which are related to other secured transactions that do not qualify for sale accounting treatment, and therefore, are treated as borrowings secured by operating and finance leases. Investors that hold securitization debt have a priority claim on the cash flows generated by their respective securitized assets to the extent that the related VIEs are required to make principal and interest payments. Investors in securitizations of these entities have 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.

	Product Warranty Liability
	The following table presents accrued product warranty and deferred warranty revenue activity:
		Six Months Ended April 30,
	(in millions)	2015			2014
	Balance at beginning of period	$	1,197		$	1,349
	Costs accrued and revenues deferred	116			153
	Currency translation adjustment	(5		)	(1		)
	Adjustments to pre-existing warranties(A)	(39		)	94
	Payments and revenues recognized	(210		)	(272		)
	Balance at end of period	1,059			1,323
	Less: Current portion	496			626
	Noncurrent accrued product warranty and deferred warranty revenue	$	563		$	697
	_________________________
	(A)	Adjustments to pre-existing warranties reflect changes in our estimate of warranty costs for products sold in prior 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.
	In the first quarter of 2015, we recognized a benefit for adjustments to pre-existing warranties of $57 million or a benefit of $0.70 per diluted share. In the first quarter of 2014, we recorded adjustments for changes in estimates of $52 million or charges of $0.64 per diluted share. In the second quarter of 2014, we recorded adjustments for changes in estimates of $42 million, or charges of $0.52 per diluted share. The impact of income taxes on the 2015 and 2014 adjustments are not material due to our deferred tax valuation allowances on our U.S. deferred tax assets.
	Extended Warranty Programs
	The amount of deferred revenue related to extended warranty programs was $425 million and $437 million at April 30, 2015 and October 31, 2014, respectively. Revenue recognized under our extended warranty programs was $38 million and $75 million, in the three and six months ended April 30, 2015, respectively, and $33 million and $60 million for the three and six months ended April 30, 2014, 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, asbestos and other product liability accruals, asset impairment 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 concentrations of our union employees. As of April 30, 2015, approximately 6,200, or 73%, of our hourly workers and approximately 300, or 5%, of our salaried workers are represented by labor unions and are covered by collective bargaining agreements. On February 9, 2015, our United Automobile, Aerospace, and Agricultural Implement Workers of America ("UAW") represented employees ratified a new four-year labor agreement that replaced the prior contract that expired October 1, 2014. Our future operations may be affected by changes in governmental procurement policies, budget considerations, changing national defense requirements, and global, political, regulatory and economic developments in the U.S. and certain foreign countries (primarily Canada, Mexico, and Brazil).
	Goodwill and Indefinite-Lived Intangible Assets
	Goodwill represents the excess of the cost of an acquired business over the amounts assigned to the net assets. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently, if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that the carrying amount is more likely than not higher than the fair value, goodwill is tested for impairment based on a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, thus the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess.
	Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The income approach is based on discounted cash flows which are derived from internal forecasts and economic expectations for each respective reporting unit.
	An intangible asset determined to have an indefinite useful life is not amortized until its useful life is determined to no longer be indefinite. Indefinite-lived intangible assets are evaluated each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of the indefinite-lived intangible asset with its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
	Significant judgment is applied when evaluating if an intangible asset has a finite useful life. In addition, for indefinite-lived intangible assets, significant judgment is applied in testing for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, and incorporating general economic and market conditions.
	During the second quarter of 2014, the economic downturn in Brazil resulted in the continued decline in actual and forecasted results for the Brazilian engine reporting unit with goodwill of $142 million and an indefinite-lived intangible asset, trademark, of $43 million. As a result, we performed an impairment analysis in the second quarter of 2014 utilizing the income approach, based on discounted cash flows, which are derived from internal forecasts and economic expectations. It was determined that the carrying value of the Brazilian engine reporting unit, including goodwill, exceeded its fair value. As a result we compared the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. A decrease in the enterprise value of the reporting unit coupled with appreciation in the value of certain tangible assets, which are not recognized for accounting purposes, resulted in the determination that the entire $142 million of goodwill was impaired. In addition, we determined that the related trademark was impaired and recognized an impairment charge of $7 million. The non-cash impairment charges were included in Asset impairment charges in the Company's Consolidated Statements of Operations. The Brazilian engine reporting unit is included in the Global Operations segment.
	Recently Adopted Accounting Standards
	In the six months ended April 30, 2015, the Company has not adopted any new accounting guidance that has had a material impact on our consolidated financial statements.
