10-K reports are financial documents filed with the Securities and Exchange Commission. Only companies that sell stock on a U.S. stock exchange are required to file them. (If a non-U.S. company sells stock on a U.S. exchange, these reports are called 20-F and are more similar to U.S. Annual reports.) Not all international companies break down their international finances by country or continent, but many do. Some may have a separate section, some may list under the Financial sections. 10-Ks can be accessed by going to the company website, or by going to the SEC website, Edgar. (Make sure that you search 10-K instead of 10K).
