|(1) |  | For purposes of computing the consolidated ratios of earnings to fixed
charges, earnings represent income before income taxes plus fixed charges.
Fixed charges, excluding interest on deposits, include interest (other
than on deposits), whether expensed or capitalized, and that portion of
rental expense (generally one third) deemed representative of the interest
factor. Fixed charges, including interest on deposits, consists of the
foregoing items plus interest on deposits.
