The risk-bearing funding ratio was developed by PPCmetrics AG in 2011. The risk capacity of a pension fund is made up of its financial and structural risk capacity. The risk-bearing funding ratio consolidates both dimensions of risk capacity in one key figure and measures the burden on the risk carriers of a pension fund. The risk carriers are the active plan members and the employers. Current pensions, on the other hand, are guaranteed by law. The higher the share of guaranteed pensions in total benefits, the more the risks are concentrated among the active plan members. The risk-bearing funding ratio creates the necessary transparency with regard to the situation of the active plan members. In contrast to the funding ratio shown in the annual financial statements, the risk-bearing funding ratio neutralises different technical interest rates and pension fund structures (pensioner share) and thus enables a direct comparison of different pension funds.
