</TABLE>

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 pretax earnings which would
have been required to cover such dividend requirements on the Corporation's
preferred stock outstanding.
