  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. Ratios for the periods
  presented reflect the reclassification, where appropriate, of Brazilian 
  translation gains and losses more fully discussed in Note 11 to the Financial 
  Statements.
