"Earnings" consist of income before income taxes and fixed charges. "Fixed
charges" consist of interest costs, including interest on deposits, and that
portion of rent expense estimated to be representative of the interest factor.
The preferred stock dividend amounts represent pre-tax earnings required to
cover dividends on preferred stock.
