  For purposes of computing the consolidated ratio of earnings to combined
fixed charges and preferred stock dividend requirements "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 (excluding 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. No tax
adjustments were made in loss years.
