For purposes of computing the consolidated ratio of earnings to fixed charges
"earnings" represent income (loss) 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.  For the year ended December 31, 1991, earnings were
insufficient to cover fixed charges. Additional earnings necessary for the year
ended December 31, 1991 to bring the ratio of earnings to fixed charges to a 
one-to-one basis are $179 million.
