Ratio of Earning to Fixed Charges

The tables below set forth the ratios of earnings to fixed charges of the
Company and its consolidated subsidiaries for the periods indicated. The ratios
have been computed using the amounts for the Company and, its consolidated
subsidiaries. Earnings available for fixed charges represent earnings from
continuing operations before income taxes and fixed charges less income from
investments accounted for by the equity method. Fixed charges represent interest
incurred and guaranteed plus that portion of rental expense deemed to be the
equivalent of interest.
