The ratio of earnings to combined fixed charges and preferred stock dividend
requirements is computed by dividing (i) income before income taxes and fixed
charges less interest capitalized during such period, net of amortization of previously
capitalized interest, by (ii) fixed charges and preferred stock dividend requirements. Fixed
charges consist of interest, expensed or capitalized, on borrowings (including or excluding
deposits, as applicable), and the portion of rental expense which is deemed representative
of interest. The preferred stock dividend requirements represent the pre-tax earnings which would
have been required to cover such dividend requirements on the Corporations Preferred Stock outstanding.
