Monthly Operating Report

On November 1, 2010, Company and certain of its U.S. subsidiaries (collectively, the “U.S. Debtors”) filed the Monthly Operating Report for the period from September 1, 2010 to September 30, 2010 (the “MOR”) with the U.S. Bankruptcy Court (In re: AbitibiBowater Inc., et al., Chapter 11, Case No. 09-11296) (the “U.S. Bankruptcy Court”). A copy of the MOR is attached as Exhibit 99.2 to this report and is incorporated herein by reference.

The MOR is limited in scope, covers a limited time period, and has been prepared solely for the purpose of the U.S. Debtors’ compliance with the monthly reporting requirements of the U.S. Bankruptcy Court. The financial information in the MOR has not been audited, reviewed or otherwise verified for accuracy or completeness by independent accountants. The financial statements in the MOR are not intended to be prepared in conformity with U.S. GAAP because they do not include all of the information and

2

footnote disclosures required by U.S. GAAP for complete financial statements, and the information contained in the MOR is not intended to reconcile to the consolidated financial statements of the Company in its Annual Report on Form 10-K for the fiscal year ended December 31, 2009 filed with the Securities and Exchange Commission on March 31, 2010, as amended, nor any consolidated financial statements in subsequently filed Quarterly Reports on Form 10-Q. The statement of operations and cash flows presented in the MOR for any interim period are not necessarily indicative of the results that may be expected for a full quarter, full year, or any interim period. Readers are cautioned not to place undue reliance on the MOR. The MOR is in a format required by the U.S. Bankruptcy Court and should not be used for investment purposes.
