"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. Pretax earnings required for preferred stock dividends were computed using tax rates for the applicable year. No tax adjustments were made in loss years.
