| Restructurings and Impairments                      | Restructurings and ImpairmentsRestructuring charges are recorded on restructuring plans that have been committed to by management and are, in part, based upon management's best estimates of future events. Changes to the estimates may require future adjustments to the restructuring liabilities. In the three months ended January 31, 2014 and 2013, the Company recognized Restructuring charges of $3 million and $2 million, respectively. In the three months ended January 31, 2014, the Company recognized Asset impairment charges of $18 million.Cost-Reductions and Other Strategic InitiativesFrom time to time, we announced actions to control spending across the Company with targeted reductions of certain costs. We are focused on continued reductions in discretionary spending, including but not limited to reductions from efficiencies, and prioritizing or eliminating certain programs or projects. We continue to focus on improving our core North America Truck and Parts businesses. We continue to evaluate our portfolio of assets, with the purpose of closing or divesting non-core/non-strategic businesses, and identifying opportunities to restructure our business and rationalize our Manufacturing operations in an effort to optimize our cost structure. The Company is currently evaluating its portfolio of assets to validate their strategic and financial fit. To allow us to increase our focus on our North America core businesses, we are evaluating product lines, businesses, and engineering programs that fall outside of our core businesses. We are using ROIC, combined with an assessment of the strategic fit to our core businesses, to identify areas that are not performing to our expectations. For those areas, we are evaluating whether to fix, divest, or close. These actions could result in additional restructuring and other related charges in the future, including but not limited to; (i) impairments, (ii) costs for employee and contractor termination and other related benefits, and (iii) charges for pension and other postretirement contractual benefits and pension curtailments. These charges could be significant.As a result of our ongoing evaluation of our portfolio of assets to validate their strategic and financial fit, which led to the discontinuation of certain engineering programs related to products that were determined to be outside of our core operations or not performing to our expectations, the North America Truck segment recognized certain charges, which included (i) accelerated depreciation of certain assets of $13 million in the first quarter of 2013, which impacted Cost of products sold in the Company's Consolidated Statements of Operations, and (ii) asset impairments of $17 million in the third quarter of 2013.In the first quarter of 2014, the Company concluded it had a triggering event related to potential sales of assets requiring assessment of impairment for certain intangible and long-lived assets in the North America Truck segment. As a result, certain amortizing intangible assets and long-lived assets were determined to be fully impaired, resulting in an impairment charge of $18 million that was recognized in Asset impairment charges in the Company's Consolidated Statements of Operations. For more information, see Note 10, Fair value measurements.Voluntary separation program and reduction-in-force actionsIn the fourth quarter of 2012, the Company offered the majority of our U.S.-based non-represented salaried employees the opportunity to apply for a voluntary separation program ("VSP"). Along with the employees who chose to participate in the VSP, we used attrition and an involuntary reduction-in-force to eliminate additional positions in order to meet our targeted reductions goal. In addition to these actions in the U.S., our Brazilian operations utilized an involuntary reduction in force to eliminate positions. In the fourth quarter of 2013, the Company leveraged efficiencies identified through redesigning our organizational structure and began implementing new cost-reduction initiatives, including an enterprise-wide reduction-in-force. As a result of these actions, the Company recognized restructuring charges of $11 million in personnel costs for employee termination and related benefits, of which a portion was paid in 2013. The Company expects the remaining restructuring charges will be paid throughout 2014.Warrenville, Illinois Lease VacancyIn the second quarter of 2012, the Company vacated the premises of its former world headquarters in Warrenville, Illinois. The cash payments associated with the lease vacancy obligation are expected to be completed by the end of 2016.North American Manufacturing Restructuring ActivitiesThe Company continues to evaluate opportunities to restructure and rationalize its Manufacturing operations in an effort to optimize our cost structure. Chatham restructuring activitiesIn the third quarter of 2011, the Company committed to close its Chatham, Ontario heavy truck plant, which had been idled since June 2009. Potential additional charges in future periods could range from $20 million to $70 million, primarily related to pension and postretirement costs and termination benefits, which are subject to employee negotiation and acceptance rates.Garland Facility closureIn the fourth quarter of 2012, the Company committed to plans for the closure of its Garland, Texas truck manufacturing operations (the "Garland Facility"). Beginning in early 2013, the Company began transitioning production from the Garland Facility to other North America operations that produce similar models. In the second quarter of 2013, production at the Garland Facility ceased. In the first and second quarters of 2013, we recognized charges of $12 million and $8 million, respectively, for the acceleration of depreciation of certain assets related to the facility that impacted Cost of products sold in the Company's Consolidated Statements of Operations.Huntsville FacilityIn February 2014, the Company announced plans to consolidate its mid-range engine manufacturing footprint and relocate mid-range engine production from its Huntsville, Alabama, facility ("Huntsville Facility") to its Melrose Park, Illinois facility ("Melrose Park Facility"). As a result, in the first quarter of 2014, the North America Truck segment recognized restructuring charges of $1 million for personnel costs related to employee terminations and $2 million for inventory reserves related to the idled production equipment at the Huntsville Facility that impacted Cost of products sold in the Company's Consolidated Statements of Operations.Restructuring LiabilityThe following tables summarize the activity in the restructuring liability, which includes amounts related to discontinued operations and excludes pension and other postretirement contractual termination benefits:(in millions)Balance at October 31, 2013 Additions Payments Adjustments Balance at January 31, 2014Employee termination charges$15 $2 $(5) $(1) $11Employee relocation costs— 1 (1) — —Lease vacancy18 — (2) — 16Other1 — (1) 1 1Restructuring liability$34 $3 $(9) $— $28(in millions)Balance atOctober 31, 2012 Additions Payments Adjustments Balance at January 31, 2013Employee termination charges$72 $— $(27) $(2) $43Employee relocation costs— 1 (1) — —Lease vacancy17 1 (2) 1 17Other— 1 — — 1Restructuring liability$89 $3 $(30) $(1) $61 |
