BD5 provides:
- a single point of reference for compilers and users of FDI statistics
- clear guidance for individual countries compiling direct investment statistics as they develop or change their statistical systems
- international standards on FDI statistics taking into account the effects of globalisation and providing the basis for economic analyses
- practical guidance to users, including on the links of FDI with other macroeconomic statistics
- an objective basis for measuring methodological differences that may exist among national statistics that need to be taken into account both for cross-country and industry analysis of FDI.
