Hi there,
Life insurance policies which pay out a pension when you reach a certain age are normally based on the Swiss third pillar of retirement savings. They generally provide both a guranteed benefit and a non-guaranteed benefit.
The guaranteed benefit or "face value" of a policy will be paid out when the policy reaches maturity, regardless of the performance of insurance company investments.
Non-guaranteed benefits are dependent on the performance of investments. These may be interest earned on equity in your policy, dividends earned on equities-linked policies, or other performance-based benefits. Interest rates can be adjusted annually and returns on equity investments can fluctuate. For this reason, the part of your benefit comprised of these returns is not guaranteed.
