* The offerings in this chart include only those that were completed on U.S. stock exchanges (NASDAQ, NYSE or AMEX) from January - August 2000. Gross proceeds include additional funding raised from the exercise of overallotment options, when disclosed.

# after-market performance is expressed as the percent change in stock price between the offering price and the closing price on 8/31/00. For underwriters with multiple offerings, the after-market performance (as a percent change) was calculated for each stock in that underwriter's "group," the percentage summed, and then averaged.
