"Fixed Charges" represent interest expense, capitalized interest and the portion of rental expense representing the interest factor. 2/ The preferred stock dividend requirements are assumed to be equal to the pretax earnings which would be required to cover such dividend requirements. The amount of such pretax earnings required to cover preferred stock dividends was computed using tax rates for the applicable year. For the years 1993 and 1992, the Corporation's effective tax rate was a negative percentage of the pretax income or loss. Therefore, for these years, the preferred stock dividends have not been adjusted to a pretax equivalent, since such an adjustment would have been antidilutive to the ratio of earnings to combined fixed charges and preferred dividends. 3/ For 1993, fixed charges exceeded earnings by $6.6 million. 4/ For the years 1993 and 1992, combined fixed charges and preferred stock dividends exceeded earnings by $19.3 million and $10.3 million, respectively.
