- ----------
(1)  The Company did not receive a tax benefit for $5 million of transaction
     costs written off to interest expense when the Company retired its
     preferred interests of subsidiaries in September 2003. Given the
     non-deductibility of the charge, $9 million of pre-tax income was required
     to cover the $5 million write-off. Accordingly, interest expense for the
     2003 period was 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 to rental payments for all
     periods presented.

(3)  The Company did 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.
