(B) For the purpose of determining the ratio of earnings to fixed charges, earnings include pre-tax income plus fixed charges. Fixed charges consist of interest on all indebtedness 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. Actual interest expense incurred (other than in the pro forma column) is reflected for the six months ended December 31, 1998 and the three months ended March 31, 1999.
