Other Events On April 13, 2009, the Company received notification from the Internal Revenue Service that its registration as an alternative fuel mixer has been approved. As a result, the Company will be eligible for a tax credit equal to $0.50 per gallon of alternative fuel used at its Demopolis, Alabama bleached paperboard mill from January 22, 2009 through the expiration of the tax credit, which is currently set at December 31, 2009. The alternative fuel eligible for the tax credit is liquid fuel derived from biomass. The Company believes that the tax credit generated with respect to the period from January 22, 2009 through March 31, 2009 will be approximately $15 million. The Company will begin booking the tax credits in the third fiscal quarter of 2009. The Demopolis mill took approximately seven days of downtime during April in connection with its previously announced maintenance shutdown. Cautionary Statement The statement herein regarding the amount of the alternative fuel tax credit generated through March 31, 2009 constitutes a forward-looking statement within the meaning of the federal securities laws. This statement is subject to certain risks and uncertainties that could cause the amount of tax credit generated to differ materially from the amount contained in the forward-looking statement. With respect to this statement, we have made assumptions regarding, among other things, the amount of the alternative fuel that the Demopolis mill produced and consumed. Management believes its assumptions are reasonable; however, undue reliance should not be placed on this estimate. ### SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
