The Securities and Exchange Commission has a very informative web site that is highlighted by the entire EDGAR database. This database contains the electronic filings that corporations are required by law to make with the SEC. The filings include company annual reports and prespectuses, among other reports, and are an excellent source of company information for researchers, investors, and the general public. According to SEC, "currently, nearly three-quarters of the publicly traded domestic companies use EDGAR to make the majority of their filings. Once all registrants become subject to electronic filing requirements (May 1996) most documents filed with the Commission will be available on EDGAR." Form definitions are given, as well as searching information and online help. Complete company, form, and master indexes are available. In addition to the EDGAR database, the SEC site provides news digests, congressional testimony, selected recent special studies, and the 1994 Annual Report of the Commission. Also available are currrent SEC proposals and enforcement actions, as well as pointers to other related sites.
