Fixed charges consist of interest on all indebtedness (including capitalized interest) plus that portion of operating lease rentals representative of the interest factor (deemed to be one-third of operating lease rentals). The Company's historical statements do not reflect the $300 million of indebtedness incurred in connection with the Distribution and, accordingly, the historical ratios of earnings to fixed charges do not reflect any interest for this indebtedness.
