Answer

Corporate insiders are a company's officers and directors, and any beneficial owners of more than ten percent of a class of the company's equity securities registered under Section 12 of the Securities Exchange Act of 1934.  Insiders must file a “statement of ownership” with the SEC on Forms 3, 4 and 5.  Go to the SEC EDGAR filings section for the filings that were made electronically, starting in May 2003. Once a company is chosen, there is a tab for insider filings by issuer or reporting owner.  

On the Business Library's Company & Financial Information section databases MergentOnline and Factiva (Companies tab), provide easy access to the SEC filings. 

Factiva: Provides a list with details for the most current information filed on a company with the SEC.  Select the Companies/Markets tab from the top of the page, search a company and in the results select Regulatory Filings.  You can then use the tab to narrow by type of filing.
