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.
