There are currently 402 non-U.S. companies that have their primarily listing on a U.S. stock exchange. This list excludes ADRs (see our list of ADRs) and stocks of companies that have cross-listed their shares on a U.S. exchange (see our list of cross-listed companies). These companies may or may not be a "foreign private issuer", as explained in what is a foreign private issuer? It is not always clear whether a company is a "U.S. company" or not. Every index provider uses their own system to determine whether a company is a "U.S. company". So we have included as an example whether the company is included in the Russell 3000 Index.
