To calculate the actuarial funding ratio, the pension fund assets are set in relation to the liabilities of a pension fund. To calculate the liabilities, the promised benefits are discounted with the technical interest rate. The actuarial funding ratio is the common regulatory key figure for the financial situation of a pension fund (Art. 44 BVV 2). Certain parameters that influence the actual financial situation of a pension fund are not necessarily taken into account in the actuarial funding ratio. These include longevity risks or the effective level of the capital market interest rate.
