At the outset it must be made clear that very often the term ‘Multinational Corporations’ is used in the literature for the TNCs. There is, however, according to some, a difference between MWCs and TNCs. According to some experts, MNCs produce commodities/products for domestic consumption of the countries in which they operate. The TNCs, on the other hand, concentrate on producing products/commodities to meet the markets of third countries; this difference is not normally made while referring to either MNCs or TNCs. Therefore, in our context MNC can also be called TNC.
Transnational corporations are defined as an organization that owns productive assets in different countries, and has common strategy formulation and implementation across borders. They are engaged in international production under the common governance of their head- quarters. Factors of production move among units located in different countries. These systems increasingly cover a variety of activities ranging from research and development to manufacturing to service functions. They are also increasingly established through mergers between existing firms from different countries or the acquisition of existing firms in the countries by firms from other countries.
UNCTAD defines Transnational Corporation as incorporated or unincorporated enterprises comprising parent enterprises and their foreign affiliates. A parent enterprise is defined as an enterprise that controls assets of countries other than its home country usually by owning a certain equity capital stake. An equity capital stake of 10 per cent or more of the ordinary Shares or voting power for an incorporated enterprise as its equivalent for an unincorporated one is normally considered as a threshold of the control of assets. Consequently, a TNC has central control with the objective of profit maximization. Central decision making is an important feature.
Subsidiary: An incorporated enterprise in the host country in which another entity directly owns more than a half of the shareholder's voting power and has the right to appoint or remove a majority of the members of the administrative management and supervisory body.
Associate: An incorporated enterprises in the host country in which an investor owns a total of at least 10 per cent but not more than a half of the shareholder's voting power.
Branch: A wholly or jointly owned unincorporated enterprise in the host country which is one of the following: (i) a permanent establishment or office of the foreign investor; and (ii) an incorporated partnership and joint-venture between the foreign direct investor and one or more third parties.
It may be added here that recently some TNCs have decentralized some of their decision making. Some TNCs do have decentralized decision making and profit centers. Yet all the final decision on a number of important issues rest with the parent. If there is no central decision, making features, the TNC does not exist, as K. Ohame once puts it.
