The Peren–Clement index is a method of country-specific risk analysis for direct investments. This analysis tool provides a guideline when deciding which foreign markets offer the possibility of additional business engagement and investment and the extent of an existing engagement or investment can be increased or should be reduced. The Peren-Clement index can be used as an early detection system, which evaluates probabilities and risks of an investment in a certain foreign market, which are determined by the political situation, its social, economical and judicial environment as well as its predictable or anticipated future developments of the analysed country.
