Supplement policy

The fund has a conditional Supplement Policy. The standard used for this is the price index for former and retired members.

Future proof supplements

The amount of supplement awarded is set annually by the Board of Trustees and depends on the Fund’s financial position. There is no right to supplements and no reserve is held for these. Supplements shall only be awarded insofar as this is future-proof. In other words, the financial position of the Pension Fund must be such that the supplement percentage to be awarded can also be paid out in the future. No supplement will be awarded if the policy funding ratio is lower than 110%.

The upper limit is set annually in such a way that it complies with the future-proof requirement.

The Board of Trustees of the Pension Fund shall have a feasibility test conducted annually in order to establish the likelihood of the indexation potential.

How do we calculate the supplement?


Funding ratio Supplement
<110% No supplement
110% - TBI Partial supplement
>TBI Full supplement


If the policy coverage ratio is between 110% and the TBI, the degree of supplementation is actuarially calculated, and then multiplied by the measure. For pensioners and former members, the price index is used as the yardstick.

The following numbers are used for the indexation calculation as of January 1, 2022:

  • TBI: 123.3%
  • Policy coverage ratio November 2021: 127,2%
  • Degree of indexation: 100% (this is an actuarial calculation, taking future indexation into account)
  • Price index: 3.28%.

The percentage of indexation to be granted is calculated as follows:

Degree of supplementation x price index = supplement percentage
On 1 January 2022, this means 100% x 3.28% = 3.28%.

This year there was also scope for catch-up indexation of 0.72%. The total amount of indexation granted as of January 1, 2022 is 3.28% regular indexation + 0.72% catch-up indexation = 4.00%.
