| (A) | Adjustments to pre-existing warranties reflect changes in our estimate of warranty costs for products sold in prior periods. Such adjustments typically occur when claims experience deviates from historic and expected trends and are also impacted by authorized field campaigns. In the second quarter of 2011, we recorded adjustments for changes in estimates of $27 million, or $0.34 per diluted share. In the third quarter of 2011, we recorded adjustments for changes in estimates of $30 million, or $0.39 per diluted share. In the third quarter of 2010, we recorded adjustments for changes in estimates of $25 million, or $0.34 per diluted share. |

| (A) | Certain impaired finance receivables are measured at fair value on a nonrecurring basis. An impairment charge is recorded for the amount by which the carrying value of the receivables exceeds the fair value of the underlying collateral, net of remarketing costs. As of July 31, 2011, impaired receivables with a carrying amount of $22 million had specific loss reserves of $13 million and a fair value of $9 million. As of October 31, 2010, impaired receivables with a carrying amount of $50 million had specific loss reserves of $23 million and a fair value of $27 million. Fair values of the underlying collateral are determined by reference to dealer vehicle value publications adjusted for certain market factors. |

| • | Our Engine segment designs and manufactures diesel engines for use globally, in Class 3 through 8 vehicles, as well as off-road applications.  In North America, these engines primarily go into our Class 6 and 7 medium trucks and buses and Class 8 heavy trucks, and are sold to original equipment manufacturers (“OEMs”).  In addition, our Engine segment produces diesel engines in Brazil primarily for distribution in South America under the MWM brand for sale to OEMs. In all other areas of the world, including North America, engines are sold under the MaxxForce brand name.  To control cost and technology, Engine has expanded its operations to included Pure Power Technologies, a components company focused on air, fuel, and aftertreatment systems to meet more stringent Euro and EPA emission standards. Also included in the Engine segment are the operating results of BDP, which manages the sourcing, merchandising, and distribution of certain service parts for vehicles we and Ford sell in North America. |

| (B) | Engineering integration costs relate to the consolidation of our truck and engine engineering operations as well as the move of our world headquarters. These costs include restructuring charges for activities at our Fort Wayne facility of $4 million and $23 million for the three and nine months ended July 31, 2011, respectively. The restructuring charges recorded are based on restructuring plans that have been committed to by management and are based upon management's best estimates of future events. Changes to the estimates may require future adjustments to the restructuring liabilities. We also incurred an additional $11 million and $18 million of other related costs for the three and nine months ended July 31, 2011, respectively. Our manufacturing segment recognized $12 million and $33 million of the engineering integration costs for the three and nine months ended July 31, 2011, respectively. For the remainder of 2011, we expect to incur approximately $36 million of additional charges related to these activities and between $80 million and $110 million of additional charges in 2012.We continue to develop plans for efficient transitions related to these activities and the optimization of our operations and management structure. |

| (C) | Restructuring of North American manufacturing operations are charges primarily related to our plans to close our Chatham, Ontario heavy truck plant and Workhorse chassis plant in Union City, Indiana, and to significantly scale back operations at our Monaco recreational vehicle headquarters and motor coach manufacturing plant in Coburg, Oregon.  These costs include restructuring charges of $53 million and related charges of $5 million for the three and nine months ended July 31, 2011. The restructuring and related charges recorded are based on restructuring plans that have been committed to by management and are based upon management's best estimates of future events. Changes to the estimates may require future adjustments to the restructuring liabilities. In addition, the Company recognized $64 million of impairment charges related to certain intangible assets and property plant and equipment primarily related to these facilities. The Truck segment recognized $119 million of restructuring of North American manufacturing operation charges for the three and nine months ended July 31, 2011. We expect to incur $40 million to $90 million of additional charges in future periods related to these activities. |
