	Each of the International Non-Contributory Retirement Plan Trust (the “Hourly Trust”), the International Retirement Plan for Salaried Employees Trust (the “Salaried Trust”), and the International Retiree Health Benefit Trust (the “Health Benefit Trust”) is a funding trust for an employee benefit plan sponsored by Navistar, Inc. (“Navistar”), a wholly owned subsidiary of Navistar International Corporation (the “Company”). The trust agreements of the Hourly Trust and the Salaried Trust provide that the trustee of the trust is only a directed trustee with respect to employer stock held by the trusts, and that the Pension Fund Investment Committee of Navistar (whose members are for the most part officers of the Company, the “PFIC”) or an investment manager designated by the PFIC, is to direct the trustee with respect to the voting or disposition of employer securities. The trust agreement for the Health Benefit Trust provides that Navistar, or an investment manager appointed by Navistar, is to direct the trustee with respect to voting and disposition of employer securities. Navistar has delegated authority for such matters to the PFIC. The Company stock held by the trusts is employer securities under these provisions. On May 8, 2006, the United States Trust Company, National Association (“US Trust”) was appointed as investment manager for each of the trusts and was given discretionary authority regarding voting and disposition of the stock. Bank of America Corporation (“BAC”) bought US Trust and served as successor in interest to US Trust’s business. Effective May 1, 2009, BAC completed the sale of its Special Fiduciary Services (“SFS”) business to Evercore Partners (“Evercore”), at which time Evercore became the successor trustee of certain trusts administered by SFS. The PFIC and the Company have the power to revoke or change the appointment of Evercore and therefore reacquire the voting and dispositive control over the Company’s stock. For this reason the PFIC, the Company or Navistar might be considered “beneficial owners” of the Company’s stock. The reporting persons may be deemed to constitute a “group” for purposes of Section 13(d)(3) of the Act. The reporting persons expressly disclaim that they have agreed to act as a group except for purposes of filing this Schedule 13G.
Item 5	Ownership of Five Percent or Less of a Class.
	If this statement is being filed to report the fact that as of the date hereof the reporting person has ceased to be the beneficial owner of more than 5 percent of the class of securities, check the following  ¨.
Item 6	Ownership of More than Five Percent on Behalf of Another Person.
	Not applicable.
Item 7	Identification and Classification of the Subsidiary Which Acquired the Security Being Reported on by the Parent Holding Company or Control Person.
	As discussed above, Navistar, the principal operating subsidiary of the Company, acquired the securities being reported herein by the Company.
Item 8	Identification and Classification of Members of the Group.
	Not applicable.
Item 9	Notice of Dissolution of Group.
	Not applicable.
Item 10	Certification.
	By signing below I certify that, to the best of my knowledge and belief, the securities referred to above were not acquired and are not held for the purpose of or with the effect of changing or influencing the control of the issuer of the securities and were not acquired and are not held in connection with or as a participant in any transaction having that purpose or effect.
