INCOME TAXES: Nucor has substantially concluded U.S. federal income tax matters for years through 2006. The 2007 through 2010 tax years are open to examination by the Internal Revenue Service. The Canada Revenue Agency is currently examining the 2006 to 2008 income tax returns for two Harris Steel entities. Management believes that the Company has adequately provided for any adjustments that may arise from this audit. The tax years 2007 through 2010 remain open to examination by other major taxing jurisdictions to which Nucor is subject (primarily Canada and other state and local jurisdictions).
