Transnational corporation has two possible definitions. In one definition, transnational is simply another word for a multinational corporation. A multinational is a business that is headquartered in one country but has subsidiaries in multiple other nations. A subsidiary is a business in which at least 50 percent plus one share of its outstanding voting stock is controlled by another company, otherwise known as a parent. While a subsidiary can act semi-autonomously within the country it is located, it is subject to the parent company. Generally, a firm is considered “multinational” when sales made outside of its home country constitute 25 percent or more of its total sales.
