ITEM 2.06 MATERIAL IMPAIRMENTS.

On November 5, 2008, executive management of Navistar International Corporation (the “Company”) concluded that a material charge for impairment related to its VEE Business Unit is required under generally accepted accounting principles applicable to the Company. The VEE Business Unit is comprised of the following asset groups: the Huntsville Engine Plant (“HEP”), the Indianapolis Engine Plant (“IEP”) and the VEE asset group which includes HEP, IEP and the Indianapolis Casting Corporation foundry (“ICC”).

Due to the significant reduction in demand from Ford Motor Company (“Ford”) for diesel engines produced by Navistar, Inc. (the principal manufacturing subsidiary of the Company) at the VEE Business Unit and the expectation that Ford’s demand for diesel engines will continue to be below previously anticipated levels, the Company concluded that a trigger event under Statement of Financial Accounting Standards No. 144 (“SFAS 144”) has occurred. The Company’s analyses under SFAS 144 have led to a conclusion that a material impairment of the carrying value of the affected assets has occurred. At this time, the Company is evaluating the fair value of the affected assets by taking into consideration current and expected future demand for its products, as well as the market value of the affected assets. This work is ongoing, but the Company estimates that it will record expenses in fiscal 2008 ranging from $375 to $430 million, the majority of which are expected to be recognized in the 4^th quarter of fiscal 2008. The expenses are expected to include $345 to $385 million of long-lived asset impairments and $30 to $45 million of other charges. Approximately $25 to $35 million of the other charges are expected to require cash outlays.

Navistar International Corporation (NYSE: NAV) is a holding Company whose wholly owned subsidiaries produce International^® brand commercial and military trucks, MaxxForce™ brand diesel engines, IC brand school and commercial buses, and Workhorse^® brand chassis for motor homes and step vans. It also is a private-label designer and manufacturer of diesel engines for the pickup truck, van and SUV markets. The Company also provides truck and diesel engine parts and service. Another affiliate offers financing services. Additional information is available at www.navistar.com.
