For purposes of calculating these ratios: (i) "fixed charges" represent interest
cost (exclusive of interest on rate refunds), amortization of debt costs and the
estimated portion of rental expense representing the interest factor; and (ii)
"earnings" represent the aggregate of pre-tax income from continuing operations
before income from equity investees, fixed charges, and distributed income of
equity investees, less capitalized interest.
