PART III - NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Navistar International Corporation (the company) is unable to timely file its Report on Form 10-K for the period ended October 31, 2005 because it is still in discussions with its registered public accounting firm, Deloitte and Touche, LLP, on a number of open items and cannot complete the preparation of the required financial information without unreasonable effort or expense. In mid December 2005, a key member of the Deloitte audit team assigned to the company went on unexpected and extended medical leave and a new audit team from Deloitte is now working to complete the year-end audit for fiscal 2005. The company and Deloitte are reviewing a number of open items, including some complex and technical accounting issues. The company continues to devote all available resources to expedite the process and bring the audit to conclusion. The company will file its Report on Form 10-K as soon as practicable following the resolution of the foregoing matters.

(2) Have all other periodic reports required under 13 or 15(d) of the Securities Exchange Act of 1934 or section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If the answer is no, identify report(s). [X] Yes [_] No
________________________________________________________________________

(3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? [_] Yes [X] No
________________________________________________________________________

If so, attach an explanation of the anticipated change, both narratively, and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

On January 17, 2006, Navistar International Corporation (the company) issued a press release announcing that it was delaying the filing of its Report on Form 10-K for the period ended October 31, 2005 because it was still in discussions with its registered public accounting firm, Deloitte and Touche, LLP, on a number of open items. The company further stated that it and Deloitte were reviewing a number of complex and technical accounting issues. While the company does not anticipate any significant change in its results of operations from the corresponding period for the last fiscal year, until resolution of the above matters is complete, the company is unable to estimate the impact the resolution of those issues may have, if any, on the company’s results of operations.
