| Principles of consolidation                                | The accompanying consolidated financial statements include the assets, liabilities, and results of operations of our manufacturing operations, majority-owned dealers, wholly-owned financial services subsidiaries, and 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 years' amounts to conform to the 2011 presentation. |

We have determined for certain of our VIEs that we are the primary beneficiary as we have the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and have the obligation to absorb losses of the VIE that could potentially be significant to the VIE 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 the consolidated entities. Assets of these entities are not 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 Motor Company ("Ford").  As a result, our Consolidated Balance Sheets include assets of $306 million and $312 million and liabilities of $158 million and $150 million as of October 31, 2011 and 2010, respectively, from BDP and BDT, including $38 million and $16 million of cash and cash equivalents, at the respective dates, which are not readily available to satisfy our other obligations. The creditors of BDP and BDT do not have recourse to our general credit. Our Financial Services segment consolidates several VIEs. As a result, our Consolidated Balance Sheets include assets of $1.8 billion and $1.7 billion as of October 31, 2011 and 2010, respectively and liabilities of $1.5 billion and $1.6 billion as of October 31, 2011 and 2010, respectively, all of which are involved in securitizations that are treated as borrowings. In addition, our Consolidated Balance Sheets include assets of $468 million and $353 million and related liabilities of $216 million and $236 million as of October 31, 2011 and 2010, respectively, all of which are involved in structures in which we transferred assets in transactions that do not qualify for sale accounting treatment and are therefore treated as borrowings. Investors that hold securitization debt have a priority claim on the cash flows generated by their respective securitized assets to the extent that those trusts are entitled to make principal and interest payments. Investors in securitizations of these entities have no recourse to the general credit of NIC or any other consolidated entity. Prior to the adoption of new guidance on accounting for transfers of financial assets on November 1, 2010, our Financial Services segment did not consolidate the assets and liabilities of the conduit funding facility of Truck Retail Accounts Corporation (“TRAC”), our consolidated special purpose entity (“SPE”), as we were not the primary beneficiary of the conduit and transfers of finance receivables to the facility qualified for sale accounting treatment. TRAC retained residual economic interests in the future cash flows of the securitized assets that were owned by the conduit. We carried these retained interests as an asset, included in Finance receivables, net on our Consolidated Balance Sheets. Subsequent to the adoption of the new accounting guidance, previous transfers of finance receivables from our Financial Services segment to the TRAC conduit retained their sales accounting treatment while prospective transfers of finance receivables no longer receive sale accounting treatment. We are also involved with 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 is 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 (loss) income of non-consolidated affiliates includes our share of the net (loss) income of these entities.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              |

The VAT is computed based on the value added to the taxed item which is then included in the price of products sold and purchased. We periodically review our VAT credit balances for recoverability based primarily on projected sales and purchases. In the past, we determined that a portion of our VAT credits were not recoverable and accordingly provided an allowance against the balance not expected to be recovered.The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“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. 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, and litigation-related accruals. Actual results could differ from our estimates.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   |

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. 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 there is a high likelihood 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, etc. The accrual of interest on such loans is discontinued when the collection of the account becomes doubtful (“non-accrual status loans”). 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. Gains or losses on sales of receivables that qualify for sales accounting treatment are credited or charged to Finance revenues in the period in which the sale occurs. Discount accretion is recognized on an effective yield basis and is included in Finance revenues.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

The difference between amortized cost and fair value is recorded as a component of Accumulated other comprehensive loss (“AOCL”) in Stockholders' Equity (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) expenses, 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.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   |

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, 2011, 2010, and 2009, 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) expenses, 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.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         |

| 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. These transactions are accounted for either as a sale with gain or loss recorded at the date of sale and a retained interest recorded, or as secured borrowings. Most of our securitization and receivable sale arrangements currently do not qualify for sales accounting 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 these transactions. Prior to an amendment to the Master Trust on July 31, 2010, our wholesale note securitization arrangements qualified for sale accounting treatment whereby the notes receivable were removed from our Consolidated Balance Sheets. Gains or losses from these sales were recognized in the period of sale based upon the relative fair value of the portion sold and the portions allocated to the retained interests, and are included in Finance revenues. Additionally, transfers of retail accounts made to a bank conduit funding facility prior to November 1, 2010, qualified for sale accounting treatment. For those transfers that previously qualified for sales accounting treatment, we retained interests in the receivables sold (transferred). The retained interests in retail accounts included receivables used as over-collateralization (“excess sellers' interests”) and cash reserves held for the benefit of the trust. Prior to July 31, 2010, the retained interest also included excess sellers' interest, cash reserves and interest only strips relating to wholesale notes. We carried these retained interests as an asset, included in Finance receivables, net on our Consolidated Balance Sheets. Our exposure to credit losses on the transferred receivables was limited to our retained interests. Other than being required to repurchase receivables that fail to satisfy certain representations and warranties provided at the time of the securitization, we are under no obligation to repurchase any transferred receivable that becomes delinquent in payment or otherwise is in default. The holders of the asset-backed securities have no recourse to us or our other assets for credit losses on transferred receivables, and have no ability to require us to repurchase their securities. We do not guarantee any securities issued by trusts. We determined the fair value of our retained interests by discounting the future expected cash flows. The future expected cash flows were primarily affected by expected payment speeds and default rates. We estimated the payment speeds for the receivables sold, the discount rate used to determine the present value of the excess sellers' interests and cash reserves, and the anticipated net losses on the receivables in order to calculate the gain or loss on arrangements that previously qualified for sales treatment. Estimates were based on historical experience, anticipated future portfolio performance, market-based discount rates, and other factors and were calculated separately for each securitized transaction. In addition, we remeasured the fair values of the retained interests on a quarterly basis and recognized changes in Finance revenues as required. The retained interests are classified as trading. We also act as servicer of transferred receivables in exchange for a fee. 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. The servicing income received by us is adequate to compensate us for our servicing responsibilities. Therefore, no servicing asset or liability is recorded. |

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. Pursuant to the adoption of new accounting guidance relating to disclosures about the allowance for losses and credit quality of finance receivables, we determined that 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, the Company determined that each portfolio consisted of one class of receivable.Troubled loan accounts are specifically identified and segregated from the remaining owned loan portfolio. The expected loss on troubled accounts is fully reserved in a separate calculation as a specific reserve. A specific reserve is recorded if it is determined that the account is impaired, and if the value of the underlying collateral is less than the principal balance of the loan. We calculate a general reserve on the remaining loan portfolio by applying loss ratios which are determined using historical loss experience in conjunction with current portfolio quality trends. The historical loss experience and portfolio quality trends of the retail portfolio segment compared to the wholesale portfolio segment are inherently different.  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 in the loss allowance for impaired accounts, we look at many of the same factors discussed above but also consider the financial strength of the customer or dealer and key management, the timeliness of payments, the number and location of satellite locations (especially for the dealer), the number of dealers of competitor manufacturers in the market area, the type of equipment normally financed, and the seasonality of the business.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |

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) expenses, 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.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.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |

A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others, (i) a significant decline in expected future cash flows, (ii) a sustained, significant decline in equity price and market capitalization, (iii) a significant adverse change in legal factors or in the business climate, (iv) unanticipated competition, and (v) slower growth rates. Goodwill is considered impaired when the fair value of a reporting unit is determined to be less than the carrying value including goodwill. The amount of impairment loss is determined based on a comparison of the implied fair value of the goodwill of the reporting unit to the actual carrying value. Intangible assets not subject to amortization are considered impaired when the fair value of the intangible asset is determined to be less than the carrying value.In 2011, the Company changed the date of our annual impairment assessments for goodwill and indefinite-lived intangible assets from October 31st to August 1st.  The Company believes that the August 1st date is preferable as it better aligns with the annual preparation of our long-term strategic plan, as well as provides additional time to complete the assessment prior to the filing of our Annual Report on Form 10-K. We use the present value of estimated future cash flows to establish the estimated fair value of our reporting units as of the testing date. This approach includes many assumptions related to future growth rates, discount rates, market comparables, control premiums and tax rates, among other considerations. Changes in economic and operating conditions impacting these assumptions could result in an impairment of goodwill in future periods. When available and as appropriate, we use comparative market multiples to corroborate the estimated fair value. 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 use of the asset to the carrying value. If the sum of the estimated undiscounted future cash flows is less than the carrying value, the fair value of the asset group is determined. The amount of impairment, if any, is calculated by subtracting the fair value of the asset from the carrying value of the asset. Our impairment loss calculations require us to apply judgments in estimating future cash flows and asset fair values. This judgment includes developing cash flow projections and assessing probability weightings to certain business scenarios. Intangible assets 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. Significant adverse changes to our business environment or expected future cash flows could cause us to record additional impairment charges in future periods, which could be material. We amortize the cost of intangible assets over their respective estimated useful lives, generally on a straight-line basis.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 |

If an investment is determined to be impaired and the decline in value is other than temporary, we record an appropriate write-down.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              |

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.

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) expenses, 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.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

Terms and conditions vary by product, customer, and country. Optional extended warranty contracts can be purchased for periods ranging from one to ten years. We accrue warranty related costs under standard warranty terms and for claims that we choose to pay as an accommodation to our customers even though we are not contractually obligated to do so. 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 base our warranty accruals on estimates of the expected warranty costs that incorporate historical information, as well as assumptions about the nature, frequency, and average cost of future warranty claims. Initial warranty estimates for new model year products are based on the previous model year product's warranty experience until the product progresses through its life cycle and related claims data becomes more mature. For initial warranty estimates related to new launch year products, we also consider historic experience from previous launches. 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 are included in Costs of products sold.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |

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. Cash flows resulting from tax benefits for deductions in excess of compensation cost recognized are included in financing cash flows.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         |

Differences arising from exchange rate changes are included in the Foreign currency translation adjustments 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.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |

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 carry forwards. 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 and other factors, it is more likely than not that all or a portion of a deferred tax asset will not be realized. Under the guidance on accounting for uncertainty in income taxes, 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. The guidance on accounting for uncertainty in income taxes also provides guidance on de-recognition, classification, interest and penalties on income taxes, and accounting in interim periods                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |

The calculation for diluted earnings per share recognizes the effect of all potential dilutive common shares 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.

Disclosure of accounting policy for its derivative instruments and hedging activities. Disclosure may include: (1) Each method used to account for derivative financial instruments and derivative commodity instruments ("derivatives"); (2) the types of derivatives accounted for under each method; (3) the criteria required to be met for each accounting method used, including a discussion of the criteria required to be met for hedge or deferral accounting and accrual or settlement accounting (for example, whether and how risk reduction, correlation, designation, and effectiveness tests are applied); (4) the accounting method used if the criteria specified for hedge accounting are not met; (5) the method used to account for termination of derivatives designated as hedges or derivatives used to affect directly or indirectly the terms, fair values, or cash flows of a designated item; (6) the method used to account for derivatives when the designated item matures, is sold, is extinguished, or is terminated. In addition, the method used to account for derivatives designated to an anticipated transaction, when the anticipated transaction is no longer likely to occur; and (7) where and when derivatives, and their related gains or losses are reported in the statement of financial position, cash flows, and results of operations and (8) an accounting policy decision to offset fair value amounts with counterparties. An entity may also describe its embedded derivatives, and the method(s) used to determine the fair values of derivatives and any significant assumptions used in such valuations.

| - Definition
Disclosure of accounting policy for the equity method of accounting for investments in common stock or other interests including unconsolidated subsidiaries, corporate joint ventures, noncontrolling interests in real estate ventures, limited partnerships, and limited liability companies. The accounting policy may include information such as: (1) initially recording an investment in the stock of an investee at cost; (2) adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses of the investee after the date of acquisition; and (3) adjustments to reflect the investor's share of changes in the investee's capital (dividends). This disclosure may also include a detailed description of the policy for determining the amount of equity method losses recognized after an investment has been reduced to zero as a result of previous losses, reasons for not using the equity method when the investor company owns 20 percent or more of the voting stock of the investee's company (including identification of the significant investee), reasons for using the equity method when the ownership percentage is less than 20 percent, and discussion of recognition of equity method losses when an investor's total investment in an investee includes, in addition to an investment in common stock, other investments such as preferred stock and loans to the investee. An entity also may describe how such investments are assessed for impairment.

| - Definition
Disclosure of accounting policy for major classes of inventories, bases of stating inventories (for example, lower of cost or market), methods by which amounts are added and removed from inventory classes (for example, FIFO, LIFO, or average cost), loss recognition on impairment of inventories, and situations in which inventories are stated above cost. If inventory is carried at cost, this disclosure includes the nature of the cost elements included in inventory.

| - Definition
Disclosure of accounting policy for investments in debt and equity securities that have readily determinable fair values (marketable securities). At a minimum, the disclosure might address accounting policies for investments classified as trading, available for sale, or held to maturity and may include how the entity determines whether impairments of available for sale or held to maturity investments are other than temporary, how the fair values of the entity's securities are determined, and the entity's accounting treatment for transfers between investment categories.

| - Definition
Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.

Disclosure of accounting policy for trade and other accounts receivables. This disclosure may include the basis at which such receivables are carried in the entity's statements of financial position (for example, net realizable value), how the entity determines the level of its allowance for doubtful accounts, when impairments, charge-offs or recoveries are recognized, and the entity's income recognition policies for such receivables, including its treatment of related fees and costs, its treatment of premiums, discounts or unearned income, when accrual of interest is discontinued, how the entity records payments received on nonaccrual receivables and its policy for resuming accrual of interest on such receivables.  If the enterprise holds a large number of similar loans, disclosure may include the accounting policy for the anticipation of prepayments and significant assumptions underlying prepayment estimates for amortization of premiums, discounts, and nonrefundable fees and costs.
