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 to bring the ratio of earnings to fixed charges to a one-to-
one basis are $162 million.
