We do not believe that claims that may be made under such guarantees would have a material effect on our financial condition, results of operations, or cash flows.In March 2010, we entered into an operating agreement, as amended, which contains automatic extensions and is subject to early termination provisions, with GE (the "GE Operating Agreement"). Under the terms of the GE Operating Agreement, as amended, GE is our preferred source of retail customer financing for equipment offered by us and our dealers in the U.S. We provide GE with a loss sharing arrangement for certain credit losses. Under the loss sharing arrangement we generally reimburse GE for credit losses in excess of the first 10% of the original value of a financed contract. The Company’s exposure to loss is mitigated because receivables financed under the GE Operating Agreement are secured by the financed equipment. We do not carry the receivables financed under the GE Operating Agreement on our Consolidated Balance Sheets. There were $1.4 billion of outstanding finance receivables at both January 31, 2014 and October 31, 2013 financed through the GE Operating Agreement and subject to the loss sharing arrangement. The related originations of these outstanding finance receivables were $2.0 billion at both January 31, 2014 and October 31, 2013. Related to certain third-party equipment financings by GE and for which we have accounted for as borrowings, we have recognized equipment leased to others of $190 million and financed lease obligations of $219 million included in our Consolidated Balance Sheets for the period ended January 31, 2014. Historically, our losses, representing the entire loss amount, on similar finance receivables, measured as a percentage of the average balance of the related finance receivable, ranged from 0.3% to 2.1%. While under limited circumstances NFC retains the right to originate retail customer financing, we expect retail finance receivables and retail finance revenues will continue to decline as our retail portfolio pays down. Based on our historic experience of losses on similar finance receivables and the nature of the loss sharing arrangement, we do not believe our share of losses related to balances currently outstanding will be material. For certain independent dealers’ wholesale inventory financed by third-party banks or finance companies, we provide limited repurchase agreements to the respective financing institution. The amount of losses related to these arrangements has not been material to our Consolidated Statements of Operations or Condensed Consolidated Statements of Cash Flows and the value of the guarantees and accruals recorded are not material to our Consolidated Balance Sheets.We also have issued limited residual value guarantees in connection with various leases. The amounts of the guarantees are estimated and recorded. Our guarantees are contingent upon the fair value of the leased assets at the end of the lease term. The amount of losses related to these arrangements has not been material to our Consolidated Statements of Operations or Condensed Consolidated Statements of Cash Flows and the value of the guarantees and accruals recorded are not material to our Consolidated Balance Sheets.We obtain certain stand-by letters of credit and surety bonds from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance-related requirements. As of January 31, 2014, the amount of  stand-by letters of credit and surety bonds was $203 million.We extend credit commitments to certain truck fleet customers, which allow them to purchase parts and services from participating dealers. The participating dealers receive accelerated payments from us with the result that we carry the receivables and absorb the credit risk related to these customers. As of January 31, 2014, we have $7 million of unused credit commitments outstanding under this program.In addition, as of January 31, 2014, we have entered into various purchase commitments of $187 million and contracts that have cancellation fees of $49 million with various expiration dates through 2019.In the ordinary course of business, we also provide routine indemnifications and other guarantees, the terms of which range in duration and often are not explicitly defined. We do not believe these will result in claims that would have a material impact on our financial condition, results of operations, or cash flows.Environmental LiabilitiesWe have been named a potentially responsible party ("PRP"), in conjunction with other parties, in a number of cases arising under an environmental protection law, the Comprehensive Environmental Response, Compensation, and Liability Act, popularly known as the "Superfund" law. These cases involve sites that allegedly received wastes from current or former Company locations. Based on information available to us which, in most cases, consists of data related to quantities and characteristics of material generated at current or former Company locations, material allegedly shipped by us to these disposal sites, as well as cost estimates from PRPs and/or federal or state regulatory agencies for the cleanup of these sites, a reasonable estimate is calculated of our share of the probable costs, if any, and accruals are recorded in our consolidated financial statements. These accruals are generally recognized no later than upon completion of the remedial feasibility study and are not discounted to their present value. We review all accruals on a regular basis and believe that, based on these calculations, our share of the potential additional costs for the cleanup of each site will not have a material effect on our financial condition, results of operations, or cash flows.Two sites formerly owned by us: (i) Solar Turbines in San Diego, California, and (ii) the Canton Plant in Canton, Illinois; were identified as having soil and groundwater contamination. Two sites in Sao Paulo, Brazil, where we are currently operating, were identified as having soil and groundwater contamination. While investigations and cleanup activities continue at these and other sites, we believe that we have adequate accruals to cover costs to complete the cleanup of all sites.We have accrued $22 million for these and other environmental matters, which are included within Other current liabilities and Other noncurrent liabilities, as of January 31, 2014. The majority of these accrued liabilities are expected to be paid subsequent to 2014.Along with other vehicle manufacturers, we have been subject to an increased number of asbestos-related claims in recent years. In general, these claims relate to illnesses alleged to have resulted from asbestos exposure from component parts found in older vehicles, although some cases relate to the alleged presence of asbestos in our facilities. In these claims, we are generally not the sole defendant, and the claims name as defendants numerous manufacturers and suppliers of a wide variety of products allegedly containing asbestos. We have strongly disputed these claims, and it has been our policy to defend against them vigorously. Historically, the actual damages paid out to claimants have not been material in any year to our financial condition, results of operations, or cash flows. It is possible that the number of these claims will continue to grow, and that the costs for resolving asbestos related claims could become significant in the future.Legal ProceedingsOverviewWe are subject to various claims arising in the ordinary course of business, and are party to various legal proceedings that constitute ordinary, routine litigation incidental to our business. The majority of these claims and proceedings relate to commercial, product liability, and warranty matters. In addition, from time to time we are subject to various claims and legal proceedings related to employee compensation, benefits, and benefits administration including, but not limited to, compliance with the Employee Retirement Income Security Act of 1974, as amended, and Department of Labor requirements. In our opinion, apart from the actions set forth below, the disposition of these proceedings and claims, after taking into account recorded accruals and the availability and limits of our insurance coverage, will not have a material adverse effect on our business or our financial condition, results of operations, or cash flows.Profit Sharing DisputesPursuant to the 1993 Settlement Agreement, the program administrator and named fiduciary of the Supplemental Benefit Program is the Supplemental Benefit Program committee (the "Committee"), comprised of non-Company individuals.  In August 2013, the Committee filed a motion for leave to amend its February 2013 complaint (which sought injunctive relief for the Company to provide certain information to which it was allegedly entitled under the Supplemental Benefit Profit Sharing Plan) and a proposed amended complaint (the "Profit Sharing Complaint") in the U.S. District Court for the Southern District of Ohio (the "Court"). Leave to file the Profit Sharing Complaint was granted by the Court in October 2013. In its Profit Sharing Complaint, the Committee alleges the Company breached the 1993 Settlement Agreement and violated ERISA by failing to properly calculate profit sharing contributions due under the Supplemental Benefit Profit Sharing Plan. The Committee seeks damages in excess of $50 million, injunctive relief and reimbursement of attorneys' fees and costs.  In October 2013, the Company filed a motion to dismiss the Profit Sharing Complaint and to compel the Committee to comply with the dispute resolution procedures set forth in the Supplemental Benefit Trust Profit Sharing Plan. The Company’s motion is currently pending before the Court.  In addition, various local bargaining units of the UAW have filed separate grievances pursuant to the profit sharing plans under various collective bargaining agreements in effect between the Company and the UAW that may have similar legal and factual issues as the Profit Sharing Complaint.   FATMA NoticeInternational Indústria de Motores da América do Sul Ltda. ("IIAA"), formerly known as Maxion International Motores S/A ("Maxion"), now a wholly owned subsidiary of the Company, received a notice in July 2010 from the State of Santa Catarina Environmental Protection Agency ("FATMA") in Brazil. The notice alleged that Maxion had sent wastes to a facility owned and operated by a company known as Natureza and that soil and groundwater contamination had occurred at the Natureza facility. The notice asserted liability against Maxion and assessed an initial penalty in the amount of R$2 million (the equivalent of approximately US$1 million at January 31, 2014), which is not due and final until all administrative appeals are exhausted. Maxion was one of numerous companies that received similar notices. IIAA filed an administrative defense in August 2010 and has not yet received a decision following that filing. IIAA disputes the allegations in the notice and intends to vigorously defend itself.Lis Franco de Toledo, et. al. vs. Syntex do Brasil and IIAAIn 1973, Syntex do Brasil Industria e Comercio Ltda. ("Syntex"), a predecessor of IIAA, our Brazilian engine manufacturing subsidiary, which was formerly known as MWM International Industria de Motores da America do Sul Ltda ("MWM"), filed a lawsuit in Brazilian court against Dr. Lis Franco de Toledo and others (collectively, "Lis Franco"). Syntex claimed Lis Franco had improperly terminated a contract which provided for the transfer from Lis Franco to Syntex of a patent for the production of a certain vaccine. Lis Franco filed a counterclaim alleging that he was entitled to royalties under the contract. In 1975, the Brazilian court ruled in favor of Lis Franco, a decision which was affirmed on appeal in 1976. In 1984, while the case was still pending, Syntex’ owner, Syntex Comercio e Participacoes Ltds ("Syntex Parent") sold the stock of Syntex to MWM, and in connection with that sale Syntex Parent agreed to indemnify and hold harmless MWM for any and all liabilities of Syntex, including its prior pharmaceutical operations (which had been previously spun-off to another subsidiary wholly-owned by the Syntex Parent) and any payments that might be payable under the Lis Franco lawsuit. In the mid to late 1990s, Syntex Parent was merged with an entity known as Wyeth Industria Farmaceutica LTDA ("Wyeth").In 1999, Lis Franco amended its pleadings to add MWM to the lawsuit as a defendant. In 2000, Wyeth acknowledged to the Brazilian court its sole responsibility for amounts due in the Lis Franco lawsuit and MWM asked the court to be dismissed from that action. The judge denied that request. MWM appealed and lost.In his pleadings, Lis Franco alleged that the royalties payable to him were approximately R$42 million. MWM believed the appropriate amount payable was approximately R$16 million. In December 2009, the court appointed expert responsible for the preparation of the royalty calculation filed a report with the court indicating royalty damages of approximately R$70 million. MWM challenged the expert’s calculation. In August 2010, the court asked the parties to consider the appointment of a new expert. MWM agreed with this request but Lis Franco objected and, in September 2010, the court accepted and ratified the expert’s calculation as of May 2010 in the amount of R$74 million and entered judgment against MWM.In September 2010, MWM filed a motion for clarification of the decision which would suspend its enforcement. The Brazilian court denied this motion and MWM appealed the matter to the Rio de Janeiro State Court of Appeals (the "Court of Appeals"). In January 2011, the Court of Appeals granted the appeal and issued an injunction suspending the lower court’s decision and judgment in favor of Lis Franco. In January 2011, MWM merged into IIAA and is now known as IIAA. An expert appointed by the Court of Appeals submitted his calculation report on October 24, 2011, and determined the amount to be R$10.85 million. The parties submitted comments to such report in December 2011, the expert replied to these comments and ratified his previous report in May 2012, and the parties again submitted comments to the expert's reply. The expert reviewed these comments and submitted a complementary report in December 2012 which determined the amount to be R$22 million. The parties submitted comments to the complementary report in January 2013. In May 2013, the Court of Appeals determined the damages amount to be R$25 million (the equivalent of approximately US$12 million at January 31, 2014). Wyeth, Lis Franco and MWM filed motions for clarification against such decision and in July 2013 the Court of Appeals denied all of these motions. MWM, Wyeth and Lis Franco filed a special appeal to the Brasilia Special Court of Appeals on August 20, 2013. The Brasilia Special Court of Appeals has not yet ruled on the special appeal.In parallel, in May 2010, MWM filed a lawsuit in Sao Paulo, Brazil, against Wyeth seeking recognition that Wyeth is liable for any and all liabilities, costs, expenses, and payments related to the Lis Franco lawsuit. In September 2012, the Sao Paulo court ruled in favor of MWM and ordered Wyeth to pay, directly to the Estate of Lis Franco de Toledo and others and jointly with MWM, the amounts of the condemnation, to be determined at the end of the liquidation proceeding. The Sao Paulo court also ordered Wyeth to reimburse MWM for all expenses, including court costs and attorney fees associated with the case. The parties were notified of the decision in October 2012, to which MWM and Wyeth filed motions for clarification of certain issues, and in December 2012, the Sao Paulo court rejected both motions. In January 2013, Wyeth filed an appeal to the San Paulo court's December 2012 decision, and in April 2013, MWM filed an answer to the appeal. The appeal was rejected by the Court of Appeals on September 10, 2013. Wyeth filed a motion for clarification to the Court of Appeals. The motion was rejected by the Court of Appeals on November 5, 2013.The parties are currently in settlement discussions with respect to these matters.Westbrook vs. Navistar. et. al.In April 2011, a False Claims Act qui tam complaint against Navistar, Inc., Navistar Defense, LLC, a wholly owned subsidiary of the Company ("Navistar Defense"), and unrelated third parties was unsealed by the United States District Court for the Northern District of Texas (the "Court"). The complaint was initially filed under seal in August 2010 by a qui tam relator ("Westbrook") on behalf of the federal government. The complaint alleged violations of the False Claims Act based on allegations that parts of vehicles delivered by Navistar Defense were not painted according to the contract specification, and improper activities in dealing with one of the vendors who painted certain of the vehicle parts. The complaint seeks monetary damages and civil penalties on behalf of the federal government, as well as costs and expenses. After the complaint was unsealed, the U.S. government notified the Court that it declined to intervene at that time. Navistar, Inc. was served with the complaint in July 2011, and a scheduling order and a revised scheduling order was entered by the Court. In December 2011, the Court granted a motion by Navistar, Inc. and Navistar Defense, along with the other named defendants to judicially estop Westbrook and his affiliated company from participating in any recovery from the action, and to substitute his bankruptcy trustee (the "Trustee") as the only person with standing to pursue Westbrook's claims. In March 2012, the Court granted motions by Navistar, Inc., Navistar Defense, and the other named defendants to dismiss the complaint. The dismissal was without prejudice and the Trustee filed an amended complaint in April 2012. In May 2012, Navistar, Inc., Navistar Defense, and the other named defendants filed motions to dismiss the amended complaint. In addition, the parties jointly filed a motion to stay discovery pending resolution of the motions to dismiss. In July 2012, the Court granted all of the defendants' motions to dismiss with prejudice, dismissing all of the claims except the claim against Navistar Defense for retaliation and the claim against Navistar, Inc. for retaliation, which was dismissed without prejudice. Plaintiff was granted leave to file an amended complaint including only the retaliation claims against Navistar Defense and Navistar, Inc. The Trustee did not file a retaliation claim against Navistar, Inc. and voluntarily dismissed without prejudice the retaliation claim against Navistar Defense. The Trustee also filed a motion for reconsideration of the dismissal of the False Claims Act claims against Navistar Defense which the Court denied. The Court issued final judgment dismissing the matter in July 2012. Westbrook filed a notice of appeal to the Fifth Circuit Court of Appeals ("Fifth Circuit") in August 2012 as to the final judgment and the motion for reconsideration as to Navistar Defense only. The Trustee filed a separate notice of appeal to the Fifth Circuit in August 2012 as to several district court orders, including the December 2011 order holding the Trustee, not Westbrook, to be the proper party in the case. In December 2012, Navistar Defense's motion to dismiss Westbrook's appeal was denied "without prejudice to reconsideration by the oral argument panel" by the Fifth Circuit. The Fifth Circuit heard oral arguments on both appeals in November 2013 but has not yet issued a ruling on either appeal.Based on our assessment of the facts underlying the claims in the above action, we are unable to provide meaningful quantification of how the final resolution of these claims may impact our future consolidated financial condition, results of operations, or cash flows.EPA Notice of ViolationIn February 2012, Navistar, Inc. received a Notice of Violation ("NOV") from the U.S. Environmental Protection Agency ("EPA"). The NOV pertains to approximately 7,600 diesel engines which, according to the EPA, were produced by Navistar, Inc. in 2010 and, therefore, should have met the EPA's 2010 emissions standards. Navistar, Inc. previously provided information to the EPA showing that the engines were in fact produced in 2009. The NOV contains the EPA's conclusion that Navistar, Inc.'s alleged production of the engines in 2010 violated the Federal Clean Air Act. The NOV states that the EPA reserves the right to file an administrative complaint or to refer this matter to the U.S. Department of Justice with a recommendation that a civil complaint be filed in federal district court. Based on our assessment of the facts underlying the NOV above, we are unable to provide meaningful quantification of how the final resolution of this matter may impact our future consolidated financial condition, results of operations or cash flows.CARB Notice of ViolationIn April 2013, Navistar, Inc. received a notice of violation and proposed settlement ("Notice") from the California Air Resources Board ("CARB"). The Notice alleges violations of the California regulations relating to verification of after-treatment devices and proposed civil penalties of approximately $2.5 million, among other proposed settlement terms. Beginning in June 2013, the Company has made settlement offers to CARB and remains in discussions regarding this matter.Based on our assessment of the facts underlying the Notice from CARB, we are unable to provide meaningful quantification of how the final resolution of this matter may impact our future consolidated financial condition, results of operations or cash flows.Shareholder LitigationIn March 2013, a putative class action complaint, alleging securities fraud, was filed against us by the Construction Workers Pension Trust Fund - Lake County and Vicinity, on behalf of itself and all other similarly situated purchasers of our common stock between the period of November 3, 2010 and August 1, 2012. A second class action complaint was filed in April 2013 by the Norfolk County Retirement System, individually and on behalf of all other similarly situated purchasers of our common stock between the period of June 9, 2010 and August 1, 2012. A third class action complaint was filed in April 2013 by Jane C. Purnell FBO Purnell Family Trust, on behalf of itself and all other similarly situated purchasers of our common stock between the period of November 3, 2010 and August 1, 2012. Each complaint named us as well as Daniel C. Ustian, our former President and Chief Executive Officer, and Andrew J. Cederoth, our former Executive Vice President and Chief Financial Officer as defendants. These complaints (collectively, the "10b-5 Cases") contain similar factual allegations which include, among other things, that we violated the federal securities laws by knowingly issuing materially false and misleading statements concerning our financial condition and future business prospects and that we misrepresented and omitted material facts in filings with the SEC concerning the timing and likelihood of EPA certification of our EGR technology to meet 2010 EPA emission standards. The plaintiffs in these matters seek compensatory damages and attorneys' fees, among other relief. In May 2013, an order was entered transferring and consolidating all cases before one judge and in July 2013, the Court appointed a lead plaintiff and lead plaintiff's counsel. The lead plaintiff filed a consolidated amended complaint in October 2013.  The consolidated amended complaint enlarged the proposed class period to June 9, 2009 through August 1, 2012, and named fourteen additional current and former directors and officers as defendants. The defendants filed Motions to Dismiss on December 17, 2013. The plaintiff filed an Omnibus Opposition to Defendants’ Motions to Dismiss, and a Motion to Strike on January 31, 2014. The defendants filed their opposition to the Motion to Strike on February 18, 2014 and filed a reply in support of their Motions to Dismiss on March 3, 2014.In March 2013, James Gould filed a derivative complaint on behalf of the Company against us and certain of our current and former directors and former officers. The complaint alleges, among other things, that certain of our current and former directors and former officers committed a breach of fiduciary duty, waste of corporate assets and were unjustly enriched in relation to similar factual allegations made in the 10b-5 Cases. The plaintiff in this matter seeks compensatory damages, certain corporate governance reforms, certain injunctive relief, disgorgement of the proceeds of certain defendants' profits from the sale of Company stock, and attorneys' fees, among other relief. Pursuant to a court order in May 2013, this matter has been stayed until the outcome of any motion to dismiss in the 10b-5 Cases.Each of these matters is pending in the United States District Court, Northern District of Illinois.In August 2013, Abbie Griffin, filed a derivative complaint in the State of Delaware Court of Chancery, on behalf of the Company and all similarly situated stockholders, against the Company, as the nominal defendant, and certain of our current and former directors and former officers. The complaint alleges, among other things, that certain of our current and former directors and former officers committed a breach of fiduciary duty, in relation to similar factual allegations made in the 10b-5 Cases. The plaintiff in this matter seeks compensatory damages, certain corporate governance reforms, certain injunctive relief, and attorneys' fees, among other relief. Pursuant to a court order in August 2013, this matter has been stayed until the outcome of any motion to dismiss in the 10b-5 Cases.Based on our assessment of the facts underlying these matters described above, we are unable to provide meaningful quantification of how the final resolution of these matters may impact our future consolidated financial condition, results of operations, or cash flows.Deloitte & Touche LLPIn April 2011, the Company filed a complaint against Deloitte and Touche LLP ("Deloitte").  In December 2012, the parties reached a settlement. As a result of this settlement in the first quarter of 2013, the Company received cash proceeds of $35 million, which were recorded as a gain to Other expense (income), net, in the Company's Consolidated Statements of Operations.OtherU.S. Securities and Exchange Commission ("SEC") InquiryIn June 2012, Navistar received an informal inquiry from the Chicago Office of the Enforcement Division of the SEC seeking a number of categories of documents for the periods dating back to November 1, 2010, relating to various accounting and disclosure issues. We received a formal order of private investigation in July 2012. We have received subsequent subpoenas from the SEC in connection with their inquiry, and we continue our full cooperation with the SEC in this matter. At this time, we are unable to predict the outcome of this matter or provide meaningful quantification of how the final resolution of this matter may impact our future consolidated financial condition, results of operations or cash flows.Non-Conformance PenaltiesIn January 2012, the EPA promulgated the Interim Final Rule establishing non-conformance penalties ("NCPs") for heavy-duty diesel ("HDD") engines, and we began using NCPs for trucks using certain of our HDD engines in 2012. Also in January 2012, the EPA published a Notice of Proposed Rulemaking for a final NCP rule (the "Final Rule"), which proposed to make NCPs available in model years 2012 and later for emissions of NOx above the 0.20g limit for both medium and heavy HDD engines.  The EPA promulgated the Final Rule for heavy HDD engines in September 2012. The Final Rule did not include NCPs for medium HDD engines. On December 11, 2013, the D.C. Circuit Court issued an opinion vacating the Final Rule. On February 10, 2014, the EPA filed a petition for panel rehearing asking the D.C. Circuit to reconsider that portion of its opinion vacating the Final Rule. The EPA's petition is currently pending. However, the Company did not plan to use the NCP rule to certify engines in model year 2014. A challenge to 2013 certificates under the Final Rule remains held in abeyance at the D.C. Circuit Court. In the three months ended January 31, 2014 and 2013, the North America Truck segment recorded charges totaling $2 million and $10 million, respectively, for NCPs for certain engine sales. |
