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