(2) These computations are included herein in compliance with Securities and Exchange Commission regulations. However, management believes that fixed charge ratios are not meaningful measures for the business of the Company because of two factors. First, even if there were no change in net income, the ratios would decline with an increase in the proportion of income which is tax-exempt or, conversely, they would increase with a decrease in the proportion of income which is tax-exempt. Second, even if there were no change in net income, the ratios would decline if interest income and interest expense increase by the same amount due to an increase in the level of interest rates or, conversely, they would increase if interest income and interest expense decrease by the same amount due to a decrease in the level of interest rates.
