

| Summary of Significant Accounting Policies     | Summary of Significant Accounting PoliciesOrganization and Description of the BusinessNavistar 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: North America Truck, North America Parts, Global Operations (collectively called "Manufacturing operations"), and Financial Services, which consists of NFC and our foreign finance operations (collectively called "Financial Services operations"). These segments are discussed in Note 16, Segment Reporting.Our fiscal year ends on October 31. As such, all references to 2014, 2013, and 2012 contained within this Annual Report on Form 10-K relate to the fiscal year, unless otherwise indicated.Basis of Presentation and ConsolidationThe accompanying audited 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. 2014 Out-Of-Period AdjustmentsIncluded in the results of operations for the year ended October 31, 2014, are out-of-period adjustments, which represent corrections of prior-period errors.  The correction of prior-period errors for the year ended October 31, 2014 was not material to the current period and any of the prior periods.  Included in the corrections were significant prior-period errors related to product warranties which resulted in a $36 million increase, primarily to the warranty liability and a corresponding increase primarily in Costs of products sold.As disclosed in Item 9A. Controls and Procedures, we concluded that a material weakness exists surrounding the validation of the completeness and accuracy of underlying data used in the determination of significant accounting estimates and accounting transactions.  Specifically, controls were not designed to identify errors in the underlying data which was used to calculate warranty cost estimates and other significant accounting estimates and the accounting effects of significant transactions.  As part of our remediation efforts for our material weakness, we performed substantive procedures to date that identified incomplete data used in calculating our warranty accrual.  2013 Out-Of-Period AdjustmentsIncluded in the results of operations for the year ended October 31, 2013 are out-of-period adjustments, which represent corrections of prior-period errors related to the accounting for certain sales transactions. In March 2010, we entered into an operating agreement with GE Capital Corporation and GE Capital Commercial, Inc. (collectively "GE"). Under the terms of the agreement, GE became our preferred source of retail customer financing for equipment offered by us and our dealers in the U.S. We provide GE a loss sharing arrangement for certain credit losses. The determination was made that certain sales that were ultimately financed by GE did not qualify for revenue recognition, as we retained substantial risks of ownership in the leased property. As a result, the transactions should have been accounted for as borrowings, resulting in the proceeds from the transfer being recorded as an obligation and amortized to revenue over the term of the financing. In addition, the equipment financing should have been accounted for as operating leases with the equipment transferred from inventory to equipment leased to others and depreciated over the term of the financing. Correcting the errors for the year ended October 31, 2013, which were not material to any of the prior periods, resulted in an $8 million increase to Net loss in our Consolidated Statements of Operations. The impact of the correction on our results for the year ended October 31, 2013 related to prior periods includes: (i) a $113 million net decrease to both Sales of manufactured products, net and Costs of products sold, which also included $37 million of additional depreciation expense, and (ii) an $8 million increase to Interest expense. In addition, in our Consolidated Statements of Cash Flows we recognized Purchases of equipment leased to others of $184 million and Proceeds from financed lease obligations of $201 million related to periods prior to fiscal 2013. The impact of the corrections was not material to any of our Consolidated Balance Sheets.Variable Interest EntitiesWe 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 $297 million and $323 million and liabilities of $250 million and $188 million as of October 31, 2014 and October 31, 2013, respectively, from BDP and BDT, including $77 million and $56 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. In December 2011, Ford notified the Company of its intention to dissolve the BDT joint venture effective December 2014. In September 2013, we agreed with Ford to extend the BDT joint venture through February 2015, and in October 2014, Ford and the Company agreed to extend the BDT joint venture through April 2015. We do not expect the dissolution of the BDT joint venture to have a material impact on our consolidated financial statements.Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include assets of $1.1 billion and $989 million as of October 31, 2014 and October 31, 2013, respectively, and liabilities of $896 million and $778 million as of October 31, 2014 and October 31, 2013, respectively, all of which are involved in securitizations that are treated as asset-backed debt. In addition, our Consolidated Balance Sheets include assets of $156 million and $61 million and corresponding liabilities of $54 million and $49 million as of October 31, 2014 and October 31, 2013, 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.Use of EstimatesThe 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 RisksOur financial condition, results of operations, and cash flows are subject to concentration risks related to concentrations of our union employees. As of October 31, 2014, approximately 6,100, or 70%, 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. Our current collective bargaining agreement with the UAW expired in October 2014 and we are currently operating under an extension of that agreement during our collective bargaining negotiations with the UAW. 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).Revenue Recognition Our Manufacturing operations recognize revenue when we meet four basic criteria: (i) persuasive evidence that a customer arrangement exists, (ii) the price is fixed or determinable, (iii) collectability is reasonably assured, and (iv) delivery of product has occurred or services have been rendered. Sales are generally recognized when risk of ownership passes. Sales to fleet customers and governmental entities are recognized in accordance with the terms of each contract. Revenue on certain customer requested bill and hold arrangements is not recognized until after the customer is notified that the product (i) has been completed according to customer specifications, (ii) has passed our quality control inspections, and (iii) is ready for delivery based upon the established delivery terms and risk of loss has transferred.An allowance for sales returns is recorded as a reduction to revenue based upon estimates using historical information about returns. For the sale of service parts that include a core component, we record revenue on a gross basis including the fair market value of the core. A core component is the basic forging or casting, such as an engine block, that can be remanufactured by a certified remanufacturing supplier. When a dealer returns a core within the specified eligibility period, we provide a core return credit, which is applied to the customer's account balance. At times, we may mark up the core charge beyond the amount we are charged by the supplier. This mark-up is recorded as a liability, as it represents the amount that will be paid to the dealer upon return of the core component and is in excess of the fair value to be received from the supplier. Concurrent with our recognition of revenue, we recognize price allowances and the cost of incentive programs in the normal course of business based on programs offered to dealers or fleet customers. Estimates are made for sales incentives on certain vehicles in dealer stock inventory when special programs that provide specific incentives to dealers are offered in order to facilitate sales to end customers. Truck sales to the U.S. and foreign governments, of non-commercial products manufactured to government specifications, are recognized using the units-of-delivery measure under the percentage-of-completion accounting method as units are delivered and accepted by the government. Certain terms or modifications to U.S. and foreign government contracts may be unpriced; that is, the work to be performed is defined, but the related contract price is to be negotiated at a later date. In situations where we can reliably estimate a profit margin in excess of costs incurred, revenue and gross margin are recorded for delivered contract items.  Otherwise, revenue is recognized when the price has been agreed with the government and costs are deferred when it is probable that the costs will be recovered. Shipping and handling amounts billed to our customers are included in Sales of manufactured products, net and the related shipping and handling costs incurred are included in Costs of products sold. Financial Services operations recognize revenue from retail notes, finance leases, wholesale notes, retail accounts, and wholesale accounts as Finance revenues over the term of the receivables utilizing the effective interest method. Certain direct origination costs and fees are deferred and recognized as adjustments to yield and are reported as part of interest income over the life of the receivable. Loans are considered to be impaired when we conclude it is probable the customer will not be able to make full payment after reviewing the customer's financial performance, payment ability, capital-raising potential, management style, economic situation, and other factors. The accrual of interest on such loans is discontinued when the loan becomes 90 days or more past due. Finance revenues on these loans are recognized only to the extent cash payments are received. We resume accruing interest on these accounts when payments are current according to the terms of the loans and future payments are reasonably assured. Operating lease revenues are recognized on a straight-line basis over the life of the lease. Recognition of revenue is suspended when management determines the collection of future revenue is not probable. Recognition of revenue is resumed if collection again becomes probable. Selected receivables are securitized and sold to public and private investors with limited recourse. Our Financial Services operations continue to service the sold receivables and receive fees for such services.     Cash and Cash Equivalents All highly liquid financial instruments with original maturities of 90 days or less, consisting primarily of U.S. Treasury bills, federal agency securities, and commercial paper, are classified as cash equivalents. Restricted cash is related to our securitized facilities, senior and subordinated floating rate asset-backed notes, wholesale trust agreements, indentured trust agreements, letters of credit, Environmental Protection Agency requirements, and workers compensation requirements. The restricted cash and cash equivalents for our securitized facilities is restricted to pay interest expense, principal, or other amounts associated with our securitization agreements. Marketable Securities Marketable securities consist of available-for-sale securities and are measured and reported at fair value. The difference between amortized cost and fair value is recorded as a component of Accumulated other comprehensive loss ("AOCL") in Stockholders' Deficit, net of taxes. Most securities with remaining maturities of less than twelve months and other investments needed for current cash requirements are classified as current in our Consolidated Balance Sheets. Gains and losses on the sale of marketable securities are determined using the specific identification method and are recorded in Other (income) expense, net. We evaluate our investments in marketable securities at the end of each reporting period to determine if a decline in fair value is other than temporary. When a decline in fair value is determined to be other than temporary, an impairment charge is recorded and a new cost basis in the investment is established. Our marketable securities are classified as Level 1 in the fair value hierarchy. Derivative Instruments We utilize derivative instruments to manage certain exposure to changes in foreign currency exchange rates, interest rates, and commodity prices. The fair values of all derivative instruments are recognized as assets or liabilities at the balance sheet date. Changes in the fair value of these derivative instruments are recognized in our operating results or included in AOCL, depending on whether the derivative instrument is a fair value or cash flow hedge and whether it qualifies for hedge accounting treatment. The Company elected to apply the normal purchase and normal sale exclusion to certain commodity contracts that are entered into to be used in production within a reasonable time during the normal course of business. For the years ended October 31, 2014, 2013, and 2012, none of our derivatives qualified for hedge accounting and all changes in the fair value of our derivatives, except for those qualifying under the normal purchases and normal sales exception, were recognized in our operating results. Gains and losses on derivative instruments are recognized in Costs of products sold, Interest expense, or Other (income) expense, net depending on the underlying exposure. The exchange of cash associated with derivative transactions is classified in the Consolidated Statements of Cash Flows in the same category as the cash flows from the items subject to the economic hedging relationships. Trade and Finance Receivables Trade Receivables Trade accounts receivable and trade notes receivable primarily arise from sales of goods to independently owned and operated dealers, original equipment manufacturers ("OEMs"), and commercial customers in the normal course of business. Finance Receivables Finance receivables consist of the following: •Retail notes—Retail notes primarily consist of fixed rate loans to commercial customers to facilitate their purchase of new and used trucks, trailers, and related equipment. •Finance leases—Finance leases consist of direct financing leases to commercial customers for acquisition of new and used trucks, trailers, and related equipment. •Wholesale notes—Wholesale notes primarily consist of variable rate loans to our dealers for the purchase of new and used trucks, trailers, and related equipment. •Retail accounts—Retail accounts consist of short-term accounts receivable that finance the sale of products to commercial customers. •Wholesale accounts—Wholesale accounts consist of short-term accounts receivable primarily related to the sales of items other than trucks, trailers, and related equipment (e.g. service parts) to dealers. Finance receivables are classified as held-to-maturity and are recorded at gross value less unearned income and are reported net of allowances for doubtful accounts. Unearned revenue is amortized to revenue over the life of the receivable using the effective interest method. Our Financial Services operations purchase the majority of the wholesale notes receivable and some retail notes and accounts receivable arising from our Manufacturing operations. The Financial Services operations retain as collateral a security interest in the equipment associated with retail notes, wholesale notes, and finance leases.Sales of Finance Receivables We sell finance receivables using a process commonly known as securitization, whereby asset-backed securities are sold via public offering or private placement. None of our securitization and receivable sale arrangements qualify for sales accounting or off-balance sheet treatment.  As a result, the transferred receivables and the associated secured borrowings are included in our Consolidated Balance Sheets and no gain or loss is recorded for the sale. We also act as servicer of transferred receivables. The servicing duties include collecting payments on receivables and preparing monthly investor reports on the performance of the receivables that are used by the trustee to distribute monthly interest and principal payments to investors. While servicing the receivables, we apply the same servicing policies and procedures that are applied to our owned receivables.Allowance for Doubtful Accounts An allowance for doubtful accounts is established through a charge to Selling, general and administrative expenses. The allowance is an estimate of the amount required to absorb probable losses on trade and finance receivables that may become uncollectible. The receivables are charged off when amounts due are determined to be uncollectible. We have two portfolio segments of finance receivables based on the type of financing inherent to each portfolio. The retail portfolio segment represents loans or leases to end-users for the purchase or lease of vehicles. The wholesale portfolio segment represents loans to dealers to finance their inventory. As the initial measurement attributes and the monitoring and assessment of credit risk or the performance of the receivables are consistent within each of our receivable portfolios, we determined that each portfolio consisted of one class of receivable.Impaired receivables are specifically identified and segregated from the remaining portfolio. The expected loss on impaired receivables is fully reserved in a separate calculation as a specific reserve based on the unique ability of the customer to pay and the estimated value of the collateral. The historical loss experience and portfolio quality trends of the retail portfolio segment compared to the wholesale portfolio segment are inherently different. A specific reserve on impaired retail receivables is recorded if the estimated fair value of the underlying collateral, net of selling costs, is less than the principal balance of the receivable. We calculate a general reserve on the remaining loan portfolio by applying loss ratios which are determined using actual loss experience and customer payment history, in conjunction with current economic and portfolio quality trends.   In addition, we analyze specific economic indicators such as tonnage, fuel prices, and gross domestic product for additional insight into the overall state of the economy and its potential impact on our portfolio.To establish a specific reserve for impaired wholesale receivables, we consider the same factors discussed above but also consider the financial strength of the dealer and key management, the timeliness of payments, the number and location of satellite locations, the number of dealers of competitor manufacturers in the market area, the type of equipment normally financed, and the seasonality of the business. Repossessions Gains or losses arising from the sale of repossessed collateral supporting finance receivables and operating leases are recognized in Selling, general and administrative expenses. Repossessed assets are recorded within Inventories at the lower of historical cost or fair value, less estimated costs to sell. Inventories Inventories are valued at the lower of cost or market. Cost is principally determined using the first-in, first-out ("FIFO") method. Property and Equipment We report land, buildings, leasehold improvements, machinery and equipment (including tooling and pattern equipment), furniture, fixtures, and equipment, and equipment leased to others at cost, net of depreciation. We initially record assets under capital lease obligations at the lower of their fair value or the present value of the aggregate future minimum lease payments. We depreciate our assets using the straight-line method over the shorter of the lease term or the estimated useful lives of the assets. The ranges of estimated useful lives are as follows:  YearsBuildings20 - 50Leasehold improvements3 - 20Machinery and equipment3 - 12Furniture, fixtures, and equipment3 - 15Equipment leased to others1 - 10Long-lived assets are evaluated periodically to determine if adjustment to the depreciation and amortization period or to the unamortized balance is warranted. Such evaluation is based principally on the expected utilization of the long-lived assets. We depreciate trucks, tractors, and trailers leased to customers under operating lease agreements on a straight-line basis to the equipment's estimated residual value over the lease term. The residual values of the equipment represent estimates of the value of the assets at the end of the lease contracts and are initially recorded based on estimates of future market values. Realization of the residual values is dependent on our future ability to market the equipment. We review residual values periodically to determine that recorded amounts are appropriate and the equipment has not been impaired. Maintenance and repairs of property and equipment are expensed as incurred. We capitalize replacements and improvements that increase the estimated useful life or productive capacity of an asset and we capitalize interest on major construction and development projects while in progress. Gains or losses on disposition of property and equipment are recognized in Other (income) expense, net. We test for impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying value of an asset or asset group (hereinafter referred to as "asset group") may not be recoverable by comparing the sum of the estimated undiscounted future cash flows expected to result from the operation of the asset group and its eventual disposition to the carrying value. If the sum of the undiscounted future cash flows is less than the carrying value, the fair value of the asset group is determined. The amount of impairment is calculated by subtracting the fair value of the asset group from the carrying value of the asset group. Included in equipment leased to others are trucks that we produced or acquired to lease to customers as well as equipment that is financed by GE that does not qualify for revenue recognition, as we retained substantial risks of ownership in the leased property, which are accounted for as operating leases and borrowings, respectively. In the Consolidated Statement of Cash Flows the related expenditures are reflected as the Purchases of equipment leased to others in the investing section.Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of an acquired business over the amounts assigned to the net assets. Goodwill is not amortized but is tested for impairment at a reporting unit level on an annual basis or more frequently, if circumstances change or an event occurs that would more likely than not reduce the fair value of a reporting unit below its carrying amount.Qualitative factors may be assessed to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If the qualitative assessment indicates that the carrying amount is more likely than not higher than the fair value, goodwill is tested for impairment based on a two-step test. The first step compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, thus the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The income approach is based on discounted cash flows which are derived from internal forecasts and economic expectations for each respective reporting unit. An intangible asset determined to have an indefinite useful life is not amortized until its useful life is determined to no longer be indefinite. Indefinite-lived intangible assets are evaluated each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Indefinite-lived intangible assets are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of the indefinite-lived intangible asset with its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Significant judgment is applied when evaluating if an intangible asset has a finite useful life. In addition, for indefinite-lived intangible assets, significant judgment is applied in testing for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, and incorporating general economic and market conditions.  Intangible assets subject to amortization are also evaluated for impairment periodically or when indicators of impairment are determined to exist. We test for impairment of intangible assets, subject to amortization, by comparing the sum of the estimated undiscounted future cash flows expected to result from the operation of the asset group and its eventual disposition to the carrying value. If the sum of the undiscounted future cash flows is less than the carrying value, the fair value of the asset group is determined. The amount of impairment is calculated by subtracting the fair value of the asset group from the carrying value of the asset group. Intangible assets, subject to amortization, could become impaired in the future or require additional charges as a result of declines in profitability due to changes in volume, market pricing, cost, manner in which an asset is used, physical condition of an asset, laws and regulations, or the business environment. We amortize the cost of intangible assets over their respective estimated useful lives, generally on a straight-line basis. The ranges for the amortization periods are generally as follows:  YearsCustomer base and relationships3 - 15Trademarks20Other3 - 18Investments in Non-consolidated Affiliates Equity method investments are recorded at original cost and adjusted periodically to recognize (i) our proportionate share of the investees' net income or losses after the date of investment, (ii) additional contributions made and dividends or distributions received, and (iii) impairment losses resulting from adjustments to fair value. We assess the potential impairment of our equity method investments and determine fair value based on valuation methodologies, as appropriate, including the present value of estimated future cash flows, estimates of sales proceeds, and market multiples. If an investment is determined to be impaired and the decline in value is other than temporary, we record an appropriate write-down. Debt Issuance Costs We amortize debt issuance costs, discounts and premiums over the remaining life of the related debt using the effective interest method. The related income or expense is included in Interest expense. We record discounts or premiums as a direct deduction from, or addition to, the face amount of the debt. Pensions and Postretirement Benefits We use actuarial methods and assumptions to account for our pension plans and other postretirement benefit plans. Pension and other postretirement benefits expense includes the actuarially computed cost of benefits earned during the current service period, the interest cost on accrued obligations, the expected return on plan assets, the straight-line amortization of net actuarial gains and losses and plan amendments, and adjustments due to settlements and curtailments. Engineering and Product Development Costs Engineering and product development costs arise from ongoing costs associated with improving existing products and manufacturing processes and for the introduction of new truck and engine components and products, and are expensed as incurred. Advertising Costs Advertising costs are expensed as incurred and are included in Selling, general and administrative expenses. These costs totaled $39 million, $48 million, and $78 million for the years ended October 31, 2014, 2013, and 2012, respectively. Contingency Accruals We accrue for loss contingencies associated with outstanding litigation for which we have determined it is probable that a loss has occurred and the amount of loss can be reasonably estimated. Our asbestos, product liability, environmental, and workers compensation accruals also include estimated future legal fees associated with the loss contingencies, as we believe we can reasonably estimate those costs. In all other instances, legal fees are expensed as incurred. These expenses may be recorded in Costs of products sold, Selling, general and administrative expenses, or Other (income) expense, net. These estimates are based on our expectations of the scope, length to complete, and complexity of the claims. In the future, additional adjustments may be recorded as the scope, length, or complexity of outstanding litigation changes. Warranty We generally offer one to five-year warranty coverage for our truck, bus, and engine products, as well as our service parts. Terms and conditions vary by product, customer, and country. We accrue warranty related costs under standard warranty terms and for certain claims outside the contractual obligation period that we choose to pay as accommodations to our customers. Our warranty estimates are established using historical information about the nature, frequency, timing, and average cost of warranty claims. Warranty claims are influenced by numerous factors, including new product introductions, technological developments, the competitive environment, the design and manufacturing process, and the complexity and related costs of component parts. We estimate our warranty accrual for our engines and trucks based on engine types and model years. Our warranty accruals take into account the projected ultimate cost-per-unit ("CPU") utilizing historical claims information. The CPU represents the total cash projected to be spent for warranty claims for a particular model year during the warranty period, divided by the number of units sold. The projection of the ultimate CPU is affected by component failure rates, repair costs, and the timing of failures in the product life cycle. Warranty claims inherently have a high amount of variability in timing and severity and can be influenced by external factors. Our warranty estimation process takes into consideration numerous variables that contribute to the precision of the estimate, but also add to the complexity of the model. Including numerous variables also reduces the sensitivity of the model to any one variable. We perform periodic reviews of warranty spend data to allow for timely consideration of the effects on warranty accruals. We also utilize actuarial analysis in order to determine whether our accrual estimate falls within a reasonable range.Initial warranty estimates for new model year products are based on the previous model year product's warranty experience until the new product progresses sufficiently through its life cycle and related claims data becomes mature. Historically, warranty claims experience for launch-year products has been higher compared to the prior model-year engines; however, over time we have been able to refine both the design and manufacturing process to reduce both the volume and the severity of warranty claims. New product launches require a greater use of judgment in developing estimates until historical experience becomes available. We record adjustments to pre-existing warranties for changes in our estimate of warranty costs for products sold in prior fiscal years. Such adjustments typically occur when claims experience deviates from historic and expected trends. In 2014, we recognized additional charges for adjustments to pre-existing warranties of $55 million. Future events and circumstances could materially change these estimates and require additional adjustments to our liability.When we identify cost effective opportunities to address issues in products sold or corrective actions for safety issues, we initiate product recalls or field campaigns. As a result of the uncertainty surrounding the nature and frequency of product recalls and field campaigns, the liability for such actions are generally recorded when we commit to a product recall or field campaign. Included in 2014 warranty expense was $13 million of charges related to field campaigns we initiated to address issues in products sold, as compared to $88 million and $130 million in 2013 and 2012, respectively. The charges were primarily recognized as adjustments to pre-existing warranties. As we continue to identify opportunities to improve the design and manufacturing of our engines we may incur additional charges for product recalls and field campaigns to address identified issues.Optional extended warranty contracts can be purchased for periods ranging from one to ten years. Warranty revenues related to extended warranty contracts are amortized to income, over the life of the contract using the straight-line method. Costs under extended warranty contracts are expensed as incurred. We recognize losses on extended warranty contracts when the expected costs under the contracts exceed related unearned revenue. When collection is reasonably assured, we also estimate the amount of warranty claim recoveries to be received from our suppliers and record them in Other current assets and Other noncurrent assets. Recoveries related to specific product recalls, in which a supplier confirms its liability under the recall, are recorded in Trade and other receivables, net. Warranty costs and recoveries are included in Costs of products sold. Although we believe that the estimates and judgments discussed herein are reasonable, actual results could differ and we may be exposed to increases or decreases in our warranty accrual that could be material.Product Warranty Liability The following table presents accrued product warranty and deferred warranty revenue activity: (in millions)2014 2013 2012Balance at beginning of period$1,349 $1,118 $598Costs accrued and revenues deferred302 469 575Divestitures— (3) —Currency translation adjustment(4) (2) (4)Adjustments to pre-existing warranties(A)(B)55 404 404Payments and revenues recognized(505) (637) (455)Balance at end of period1,197 1,349 1,118Less: Current portion535 601 551Noncurrent accrued product warranty and deferred warranty revenue$662 $748 $567_________________________(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. Inthe first quarter of 2014, we recorded adjustments for changes in estimates of $52 million or $0.64 per diluted share. In the second quarter of 2014, we recorded adjustments for changes in estimates of $42 million, or $0.52 per diluted share. In the third quarter of 2014, we recognized a benefit for adjustments to pre-existing warranties of $(29) million, or $(0.36) per diluted share.  Included in the 2014 adjustments is a $36 million correction of prior-period errors, primarily related to pre-existing warranties.  For more information on the errors identified, see 2014Out-of-Period Adjustments.  The impact of income taxes on the 2014 adjustments is not material due to our deferred tax valuation allowances on our U.S. deferred tax assets.Inthe first quarter of 2013, we recorded adjustments for changes in estimates of $40 million or $0.50 per diluted share. In the second quarter of 2013, we recorded adjustments for changes in estimates of $164 million, or $2.04 per diluted share. In the third quarter of 2013, we recorded adjustments for changes in estimates of $48 million, or $0.60 per diluted share.  In the fourth quarter of 2013,  we recorded adjustments for changes in estimates of $152 million, or $1.89 per diluted share. The impact of income taxes on the 2013 adjustments is not material due to our deferred tax valuation allowances on our U.S. deferred tax assets. In the first quarter of 2012, we recorded adjustments for changes in estimates of $123 million, or $1.76 per diluted share. In the second quarter of 2012, we recorded adjustments for changes in estimates of $104 million, or $1.51 per diluted share. In the fourth quarter of 2012, we recorded adjustments for changes in estimates of $149 million, or $2.16 per diluted share.  (B)In the first quarter of 2013, we recognized $13 million of charges for adjustments to pre-existing warranties for a specific warranty issue related to component parts from a supplier. Also during the first quarter of 2013, we reached an agreement for reimbursement from this supplier for this amount and other costs previously accrued. As a result of this agreement, we recognized a recovery of $27 million within Costs of products sold and recorded a receivable within Other current assets. In the second quarter of 2013, we recognized a warranty recovery of $13 million within Income (loss) from discontinued operations, net of tax and recorded a receivable within Other current assets.In the third quarter of 2012, we recognized $10 million of adjustments to pre-existing warranties for a specific warranty issue related to component parts from a supplier. Also during the quarter, we reached agreement for reimbursement from such supplier and recognized a recovery for that amount and recorded a receivable within Other current assets.Extended Warranty ProgramsThe amount of deferred revenue related to extended warranty programs was $437 million, $420 million, and $364 million at October 31, 2014, 2013, and 2012 respectively. Revenue recognized under our extended warranty programs was $132 million, $87 million, and $63 million in the years ended October 31, 2014, 2013, and 2012 respectively. In 2014, amounts recognized related to extended warranty contracts on our MaxxForce Big-Bore engines was not material to the Company's Consolidated Statements of Operations. In 2013 we recognized net charges of $161 million related to extended warranty contracts on our MaxxForce Big-Bore engines, which includes charges of $127 million related to pre-existing warranties.  In 2012 we recognized net charges of $66 million for losses on extended warranty contracts for our 2010 emissions standard MaxxForce Big-Bore engines. The net charges included $19 million related to contracts sold in 2012 and $47 million recognized as adjustments to pre-existing warranties. Future warranty experience, pricing of extended warranty contracts, and external market factors may cause us to recognize additional charges as losses on extended service contracts in future periods.Stock-based CompensationWe have various plans that provide for the granting of stock-based compensation to certain employees, directors, and consultants, which is further described in Note 19, Stock-Based Compensation Plans. Shares are issued upon option exercise from Common stock held in treasury. For transactions in which we obtain employee services in exchange for an award of equity instruments, we measure the cost of the services based on the grant date fair value of the award. We recognize the cost over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period (usually the vesting period). Costs related to plans with graded vesting are generally recognized using a straight-line method. Foreign Currency TranslationWe translate the financial statements of foreign subsidiaries whose local currency is their functional currency to U.S. dollars using period-end exchange rates for assets and liabilities and weighted average exchange rates for each period for revenues and expenses. Differences arising from exchange rate changes are included in the Foreign currency translation adjustment component of AOCL. For foreign subsidiaries whose functional currency is the U.S. dollar, we remeasure non-monetary balance sheet accounts and the related income statement accounts at historical exchange rates. Gains and losses arising from fluctuations in currency exchange rates on transactions denominated in currencies other than the functional currency are recognized in earnings as incurred. We recognized net foreign currency transaction losses of $21 million, $23 million, and $25 million in 2014, 2013, and 2012 respectively, which were recorded in Other (income) expense, net. Income Taxes We file a consolidated U.S. federal income tax return for NIC and its eligible domestic subsidiaries. Our non-U.S. subsidiaries file income tax returns in their respective local jurisdictions. We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax benefit carryforwards. Deferred tax assets and liabilities at the end of each period are determined using enacted tax rates. A valuation allowance is established or maintained when, based on currently available information, it is more likely than not that all or a portion of a deferred tax asset will not be realized. We recognize the tax benefit from an uncertain tax position claimed or expected to be claimed on a tax return only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The tax benefits recognized in the 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.We apply the intraperiod tax allocation rules to allocate income taxes among continuing operations, discontinued operations, extraordinary items, other comprehensive income (loss), and additional paid-in capital when we meet the criteria as prescribed in the rules.Earnings Per Share The calculation of basic earnings per share is based on the weighted average number of our shares of common stock outstanding during the applicable period. The calculation for diluted earnings per share recognizes the effect of all potential dilutive shares of common stock that were outstanding during the respective periods, unless their impact would be anti-dilutive. Diluted earnings per share recognizes the dilution that would occur if securities or other contracts to issue common stock were exercised or converted into shares using the treasury stock method. Recently Adopted Accounting Standards  In the year ended October 31, 2014, 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 FASB issued Accounting Standards Update ("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. We are currently evaluating the impact and method of adoption of this ASU on our consolidated financial statements. |
