TONTINE PLAN
Tontine plans in the Netherlands are linked endowment savings contracts with a specific bonus structure. Policyholders can choose from several AEGON funds to invest premiums paid. The main characteristic of a tontine system is that when the policyholder dies, the balance is not paid out to the policyholder’s estate, but is distributed at the end of the year to the surviving policyholders of the specific series to which the deceased policyholder belonged. In general, a new series starts at the beginning of each calendar year, but there are also open ended tontine plans in the portfolio. When the policyholder dies before maturity, AEGON The Netherlands pays a death benefit equal to the premiums paid accumulated at a 4% compound interest, subject to a minimum of 110% of the fund value during the first half of the contract term. Separate account group contracts of AEGON The Netherlands are large group contracts that have an individually determined asset investment underlying the pension contract. The guarantee given is that the profit sharing is the minimum of 0% or the realized return (on an amortized cost basis), both corrected for the technical interest of either 3% or 4%. If there is a negative profit sharing, the 0% minimum is effective, but the loss in any given year is carried forward to be offset against any future surpluses. In general, a guarantee is given for the life of the underlying employees so that their pension benefit is guaranteed. For AEGON The Netherlands, within individual unit-linked policies, the sum insured at maturity or upon the death of the beneficiary has a minimum guaranteed return (of 3% or 4%) if the premium has been paid for a consecutive period of at least ten years and is invested in a mixed fund and/or fixed-income funds. No guarantees are given for equity investments only.
