| Restructuring                        | RestructuringThe Company recognized $2 million and $24 million of restructuring charges for the three and six months ended April 30, 2011, respectively, primarily related to restructuring activities at our Fort Wayne facility and Springfield Assembly Plant. The Company recognized $3 million of restructuring charges and $14 million of restructuring benefits for the three and six months ended April 30, 2010, respectively, primarily related to restructuring activities at our Indianapolis Engine Plant (“IEP”) and Indianapolis Casting Corporation (“ICC”) locations. The restructuring charges recorded are based 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.The Company is utilizing proceeds from our October 2010 tax-exempt bond financing to finance the relocation of the Company’s world headquarters site, the expansion of an existing warehouse facility, and the development of certain industrial facilities to facilitate the consolidation of certain operations. In the first quarter of 2011, the Company finalized the purchase of the property and buildings that we intend to develop into our new world headquarters site. We continue to develop plans for efficient transitions related to these activities and the optimization of our operations and management structure. Restructuring charges related to these activities include $1 million and $19 million for the three and six months ended April 30, 2011, respectively.  In addition, we incurred other related charges of $5 million and $7 million for the three and six months ended April 30, 2011, respectively.  For fiscal 2011, we expect to incur approximately $50 million of additional restructuring and related charges associated with these activities. In future periods as plans are developed, we expect to incur additional charges, as well as achieve optimization savings, beyond 2011.Fort Wayne and Springfield restructuring activityOn October 30, 2010, our United Automobile, Aerospace and Agricultural Implement Workers of America (“UAW”) represented employees ratified a new four-year labor agreement that replaced the prior contract that expired October 1, 2010. The new contract allows the Company additional flexibility in manufacturing decisions and includes provisions for the wind-down of UAW positions at our Fort Wayne facility. As a result of the contract ratification and planned wind-down of UAW positions at our Fort Wayne facility, the Truck segment recognized $9 million of restructuring charges in the fourth quarter of 2010. The restructuring charges consisted of $5 million in personnel costs for employee termination and related benefits and $4 million of charges for pension and other postretirement contractual termination benefits.In the first quarter of 2011, the Company committed to a plan to wind-down and transfer certain operations at our Fort Wayne facility. In addition, certain employees at our Springfield Assembly Plant accepted retirement and separation incentive agreements. As a result of the restructuring activities, the Truck segment recognized an additional $1 million and $23 million of restructuring charges for the three and six months ended April 30, 2011, respectively. The restructuring charges consisted of $17 million in personnel costs for employee termination and related benefits, $5 million of charges for pension and other postretirement contractual termination benefits and $1 million of employee relocation costs. We expect the restructuring charges, excluding pension and other postretirement costs, will be paid over the next two to three years. The following table summarizes the activity in the restructuring liability related to Fort Wayne and Springfield, which excludes pension and other postretirement contractual termination benefits:   Balance atOctober 31, 2010 Additions Payments Adjustments Balance atApril 30, 2011(in millions)          Employee termination charges $5 $17 $(4) $— $18Employee relocation costs — 1 (1) — —Restructuring liability $5 $18 $(5) $— $18 Ford related restructuring activityIn the first quarter of 2010, the Company recognized $17 million of restructuring benefits related to restructuring activity at our IEP and ICC locations. The restructuring benefit primarily related to the settlement of a portion of our other contractual costs for $16 million within the restructuring liability. The following table summarizes the activity in the restructuring liability related to Ford, which excludes pension and other postretirement contractual termination benefits charges, and the pension curtailment:   Balance atOctober 31, 2009 Additions Payments Adjustments Balance atApril 30, 2010(in millions)          Employee termination charges $20 $— $(10) $(1) $9Other contractual costs 21 — (5) (16) —Restructuring liability $41 $— $(15) $(17) $9 |
