This database is comprised of all emerging growth initial public offerings (IPOs) on American stock exchanges and filed with the Securities and Exchange Commission (SEC) from January 1990 through December 2010. From this list the following types of firms and filings were excluded: mutual funds, real estate investment trusts (REITs), asset acquisition or blank check companies, foreign F-1 filers, and all spin-offs and other firms that were not true emerging growth firms.
Every firm going public must file a registration statement and a prospectus with the SEC prior to its initial stock offering. This database has been constructed directly from these registration statements and prospectuses. For companies that went public in June 1996 and later these documents were found on the SEC’s Electronic Data, Gathering and Retrieval (EDGAR) website. For IPOs prior to June 1996 we have relied on IPO registration statements and prospectuses that were originally found in paper form.
This database contains variables that pertain to the firm going public and the offering itself. Each firm is assigned a Central Index Key by the SEC which we are using as the firm’s unique identifier. All of the variables in this database are extracted from each firm’s prospectus (form 424B) or the firm’s registration statement (form S-1).
The data is found in two Excel databases. The Firm IPO database contains data on the firm such as company name, location of headquarters, initial share price, year of founding and SIC. This database has information on 3,939 individual firms. The Management and Director database contains the name, age, position, and biography of all of the managers and directors of these firms. This database has information on 43,695 individuals, each of whom is uniquely identified.
