(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.
