(1) 
The ratios of earnings to fixed charges for the fiscal years ended 2012, 2011, 2010, and 2009 have been revised to exclude capitalized interest from the calculation of Earnings before Taxes and Fixed Charges. Capitalized interest was not material to the calculation of Earnings before Taxes and Fixed Charges or the Ratio of Earnings to Fixed Charges in prior periods. Interest on uncertain tax positions is included in Interest Expense.
(2) 
The Estimated Interest Portion of Rental Expense is calculated by using our estimated incremental borrowing rate times the present value of projected operating lease payments.
(3) Excludes recognition of Allowance for Borrowed Funds Used During Construction.
