Form 20-F vs 10-K: Annual Reports for Foreign and US Companies
Short answer. Form 10-K is the annual report for US domestic filers and uses US GAAP. Form 20-F is the annual report for foreign private issuers listed in the US, such as many ADR issuers, and may use IFRS without reconciliation to US GAAP. Foreign issuers also skip quarterly 10-Qs, filing 6-Ks for interim news instead.
