"A 6-K form is one used by non-US based companies to disclose all information which is not covered in their quarterly / annual financial statements. This is filed with the SEC and is used in order to provide US investors with the same degree of information that would be available to investors based in the same country as the company.
Any foreign company wishing to attract US investors must file a 6-K form with the SEC along with any financial statements"
Hmmm....
