A Form 4 filing must be filed with the SEC whenever there is a change in the holdings of company insiders. An insider is defined as any officer and/or beneficial owner who is buying or selling their company’s stock is required to file a Form 4. Any shareholders owning 10% or more of the company’s outstanding stock also must file a Form 4.

Form 4 is a United States SEC filing that relates to insider trading. Every director, officer or owner of more than 10% of a class of equity securities registered under Section 12 of the Securities Exchange Act of 1934 must file with the United States Securities and Exchange Commission a statement of ownership regarding such security. The initial filing is on Form 3 and changes are reported on Form 4. The annual statement of beneficial ownership of securities is on Form 5. The forms contain information on the reporting person's relationship to the company and on purchases and sales of such equity securities.
Form 4 is stored in SEC's EDGAR database.
A Form 4 must be filed before the end of the second business day following a change in ownership of securities or derivative securities (including the exercise or grant of stock options) for individuals subject to Section 16 of the Securities Exchange Act of 1934.
