Given the non-deductibility of the charge, $9 million of pre-tax income is required to cover the $5 million write-off. Accordingly, interest expense has been grossed up by $4 million. (2) Represents the portion of rental expense assumed to be attributable to interest factors of related rental obligations determined at interest rates appropriate for the period during which the rental obligations were incurred. Approximately 32 to 34 percent applies for all periods presented. (3) The Company does not receive a tax benefit for a portion of its preferred interests of consolidated subsidiaries. This amount represents the pre-tax earnings that would be required to cover preferred interests requirements of consolidated subsidiaries. In September 2003, the Company retired its preferred interests of subsidiaries. (4) The Company does not receive a tax benefit for its preferred stock dividends. This amount represents the pre-tax earnings that would be required to cover its preferred stock dividends. (5) Earnings in 1998 were inadequate to cover fixed charges and combined fixed charges and preferred stock dividends by $237 million and $240 million, respectively.
