This press release represents a continuation of the Company's practice of issuing a mid-quarter financial highlights update. (Dollars in thousands) Average Loans, Net of Unearned Income - $1,596,844 Average Interest-Earning Assets - $4,671,123 Average Deposits - $4,463,724 Net Interest Margin - 6.9% Yield on Loans - 11.7% Yield on Interest-Earning Assets - 8.0% Cost of Funds - 1.1% Efficiency Ratio - 43.9% Warrant Income - $11,151 Venture Capital Gains - $1,700 Off-Balance Sheet Client Funds - $10,001,986 Based on May 31, 2000 market valuations, the Company had additional potential pre-tax warrant gains totaling $23.3 million. The Company is restricted from selling many of these warrants until the second, third and fourth quarters of 2000. As of May 31, 2000, the Company held 1,035 warrants in 2 companies and had made investments in 172 venture capital funds and direct equity investments in 37 companies. Many of these companies are non-public. Thus, for those companies for which a readily determinable market value cannot be obtained, the Company values those equity instruments at cost less any identified impairment. Additionally, the Company is typically precluded from using any type of derivative instrument to secure the current unrealized gains associated with many of the warrants. Hence, the amount of income realized by the Company from the warrants in future periods may vary materially from the current unrealized amount due to fluctuations in the market prices of the underlying common stock of these companies. Furthermore, the Company may reinvest some or all of the income realized from the disposition of warrants in pursuing its business strategies. As of May 31, 2000, the Company has identified two loans with principal amounts aggregating approximately $13.0 million, that, on the basis of information known to the Company, were judged to have a higher than normal risk of becoming nonperforming. This release includes "forward-looking statements" as that term is used in the securities laws. All statements regarding the Company's expected financial position, business and strategies are forward-looking statements. In addition, in this release the words "anticipates," "believes," "estimates," "seeks," "expects," "plans," "intends" and similar expressions, as they relate to the Company or its management, are intended to identify forward-looking statements. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable, and has based these expectations on the Company's beliefs as well as assumptions it has made, such expectations may prove to be incorrect.
