A foreign company listed in the US files a Form 6-K for what it publishes at home: results, share buybacks, directors' dealings, bond issues and notices. The 6-K carries no item numbers, so each is listed under the title the company gave EDGAR, where it gave one; the rest are linked to the filing itself. The annual report is the 20-F (or the 40-F for a Canadian filer). Form 144, 13F and Schedule 13D and 13G have their own pages; a foreign filer files no Form 4.
