We are focused on continued reductions in discretionary spending, including reductions resulting from efficiencies, and prioritizing or eliminating certain programs or projects. Voluntary separation program and reduction-in-force actionsIn 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. In the second quarter of 2014, the Company initiated new cost-reduction actions, including an enterprise-wide reduction-in-force. As a result of these actions, the Company recognized restructuring charges of $8 million in personnel costs for employee termination and related benefits, the majority of which was paid during 2014 and 2015.In the third quarter of 2015, the Company initiated new cost-reduction actions, including a reduction-in-force in the U.S. and Brazil.  As a result of these actions, the Company recognized restructuring charges of $13 million in personnel costs for employee termination and related benefits, which will be paid throughout 2015 and 2016. In the fourth quarter of 2015, the Company offered the majority of our U.S.-based non-represented salaried employees the opportunity to apply for a voluntary separation program ("VSP"). As a result of these actions, the Company recognized restructuring charges of $37 million. The restructuring charges primarily consist of personnel costs for employee termination and related benefits. In addition, the Company initiated new cost-reduction actions, including a reduction-in-force in Brazil.  As a result of these actions, the Company recognized restructuring charges of $10 million in personnel costs for employee termination and related benefits, which will be paid throughout 2016. North American Manufacturing Restructuring ActivitiesWe continue to focus on our core 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 an ROIC methodology, 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 curtailments. These charges could be significant.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 $0 million to $60 million, primarily related to pension, postretirement costs and termination benefits, which are subject to employee negotiation, acceptance rates and the resolution of disputes related thereto. Based on a ruling received from the Financial Services Tribunal in Ontario, Canada, in the third quarter of 2014, the Company recognized additional charges of $14 million related to the 2011 closure of its Chatham, Ontario plant. The Company appealed this ruling, but it was upheld in a July 3, 2015 decision issued by the Divisional Court of Ontario.  On July 23, 2015, the Company filed a notice of motion for leave to appeal to the Court of Appeal for Ontario. The appeal was perfected on August 25, 2015 through an additional filing.  See Note 11, Postretirement benefits for further discussion.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 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 Costs of products sold in the Company's Consolidated Statements of Operations.Foundry FacilitiesIn December 2014, we announced the closure of our Indianapolis, Indiana foundry facility and on June 30, 2015, we closed this foundry.  In addition, on April 30, 2015, we sold our Waukesha, Wisconsin foundry operations. As a result, in 2014, the Truck segment recognized restructuring charges of $13 million, which are included in Restructuring charges in the Company's Consolidated Statements of Operations.  The restructuring charges consist of $2 million in personnel costs for employee termination and related benefits and $11 million of charges for pension and other postretirement contractual termination benefits.  The restructuring charges relating to employee terminations were paid throughout 2015.  Also in the fourth quarter of 2014, the Truck segment recognized $7 million for inventory reserves related to the foundry facilities that impacted Costs of products sold in the Company's Consolidated Statements of Operations. In addition, in the fourth quarter of 2014, the Truck segment recognized $7 million of charges for impairments of property and equipment.  The Waukesha asset group was reviewed for recoverability by comparing the carrying value to estimated future undiscounted cash flows and those carrying values were determined not to be fully recoverable.  We utilized the market approach to determine the fair value of the asset group.  These charges were recorded in Asset impairment charges in the Company's Consolidated Statements of Operations. During 2015, the Truck segment recognized charges of $28 million in 2015 for the acceleration of depreciation of certain assets related to the foundry facilities. These charges are reported within Costs of products sold in the Company's Consolidated Statements of Operations.Asset Impairments The following table reconciles our impairment charges in our Consolidated Statements of Operations(in millions)2015 2014 2013Goodwill impairment charge(A)$— $142 $81Intangible asset impairment charge7 7 —Other asset impairment charges related to continuing operations23 34 20Other asset impairment charges related to discontinued operations— — 4Total asset impairment charges$30 $183 $105_________________________(A)For more information, see Note 8, Goodwill and Other Intangible Assets, Net. The Goodwill impairment charge in 2013 includes $4 million related to discontinued operations. In the fourth quarter of 2015, the Company recognized a total non-cash charge of $7 million for the impairment of certain intangible and long-lived assets in the Brazil truck asset group.  As a result of the continued operating losses and idled production in the asset group, we tested the indefinite-lived intangible and long-lived assets for potential impairment.  As a result, we determined that $4 million of intangible assets and $3 million of certain long-lived assets were impaired. During the third and fourth quarters of 2015, the Company concluded it had a triggering event related to certain long-lived assets in the Truck segment.  As a result, certain long-lived assets were determined to be impaired, resulting in a charge of $3 million and $4 million, respectively. In addition, in the third quarter of 2015, the economic downturn in Brazil resulted in the continued decline in actual and forecasted results for the Brazilian engine reporting unit with an indefinite-lived intangible asset, trademark, of $24 million.  As a result, we performed an impairment analysis in the third quarter of 2015 utilizing the income approach, based on discounted cash flows, which are derived from internal forecasts and economic expectations. It was determined that the carrying value of the trademark exceeded its fair value. As a result, we determined that the trademark was impaired and recognized an impairment charge of $3 million. In the first quarter of 2015, the Company concluded it had a triggering event related to certain operating leases. As a result, the Truck segment recorded $7 million of asset impairment charges.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 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 $19 million that was recognized in the year ended October 31, 2014. The 2013 other asset impairment charges primarily consisted of $19 million for the impairment of assets that resulted from the discontinuation of certain engineering programs. |
