The index evaluates jurisdiction laws and monitors the volume of corporate financial activity entering and leaving jurisdictions. A Haven Score is determined by more than 70 questions under 18 indicators to find the extent to which a jurisdiction’s laws and regulations allow for corporate tax abuse. The outcome of these indicators are then combined with global scale weights, which are based on IMF data on foreign direct investments. The final figure is a measure of the contribution of each jurisdiction to the global problem of corporate tax abuse.
