Transnational corporations (TNCs) are incorporated or unincorporated enterprises comprising parent enterprises and their foreign affiliates. A parent enterprise is defined as an enterprise that controls assets of other entities in 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, or its equivalent for an unincorporated enterprise, is normally considered as a threshold for the control of assets (in some countries, an equity stake other than that of 10 per cent is still used. In the United Kingdom, for example, a stake of 20 per cent or more was a threshold until 1997.).
In 2006, Gazprom sold 316 billion cubic metres (11.2 trillion cubic feet) of gas to domestic customers; 162 billion cubic metres (5.7 trillion cubic feet) to the rest of Europe; and 101 billion cubic metres (3.6 trillion cubic feet) to CIS countries and the Baltic states. Gazprom receives about 60 percent of its revenue from its sales to European customers.

Вы вообще в курсе, какие требования в ЕС существуют по "демонополизации" при поставке газа? Есди в курсе, то должны знать о взимопроникновении (для соблюдения формальных норм) газовых европейских компаний. Там просто нельзя быть "национальной компанией" - на только технические и юридические требования противоречат друг другу.
