For purposes of computing the consolidated ratio of earnings to combined fixed
charges and preferred stock dividend requirements "earnings" represent income
before extraordinary items and cumulative effect of changes in accounting
principles plus applicable income taxes and fixed charges.  "Fixed charges"
include gross interest expense (including interest on deposits) and the
proportion deemed representative of the interest factor of rent expense, net of
income from subleases.  Pretax earnings required for preferred stock dividends
were computed using tax rates for the applicable year.
