This document summarizes the work of the Formula Consultative Task Team in South Africa to determine an appropriate formula for the country's Risk Equalisation Fund (REF). The REF aims to promote equity and solidarity in South Africa's transition to a social health insurance system with mandatory membership. The Task Team considered evidence and principles for choosing risk factors to include in the REF formula. Key risk factors identified were age, gender, births/first year of life, chronic diseases, and last year of life. The document also discusses defining the scope of benefits to be equalized and guidelines for REF operations and inclusion of different medical scheme types. The goal was to establish a formula that fairly allocates risk across schemes based on member characteristics.
