The EuroGroups Register (EGR) is a network of registers, consisting of a central register kept at Eurostat and registers in each EU Member State and in EFTA countries. The central register contains information about multinational enterprise groups, which have statistically relevant financial and non-financial transnational operations in at least one of the European countries. Registers in the EU Member States and in EFTA countries contain information regarding multinational enterprise groups active in the respective countries and are fully consistent with the central register. The aim of the EGR network is to hold a complete, accurate, consistent and up-to-date set of linked and coordinated statistical registers, which offer compilers a common frame of multinational enterprise groups, global as well as truncated national groups, operating in the economy of the EU and EFTA countries, together with their constituent legal units and enterprises and the ownership and control relationships between legal units.
