The revised Benchmark Definition provides methods for classifying different types of FDI (e.g. mergers and acquisitions greenfield investments) and for identifying the ultimate investor. The new edition now addresses the uses of FDI statistics including globalisation indicators and provides a chapter relating to the statistics on the activities of multinational enterprises.
