Note on the Computation of Ratio of Earnings to Fixed Charges: For the purpose of determining the ratio of earnings to fixed charges, earnings include pre-tax income from continuing operations plus fixed charges. Fixed charges consist of interest expense and an estimate of the interest within rental expense deemed by us to be representative of the interest factor of rental expense, which we estimate to be 30% of such expense. During the periods presented above, we had no preference securities outstanding.
