The payments are guaranteed for the period opted for by the annuitant. For instance, if you are opting for a 5 year term annuity, the guarantee is for 5 years, for 10 year term it is for 10 years etc.
Guarantee means that should you die before the end of the fixed term, then the remaining payments for the stated term will continue to the person nominated by you for this purpose (the nominee).
Your nominee can apply to have the remaining installments exchanged for a lump sum at a rate set by the FNPF after taking actuarial advice. At the end of the term, payments cease, and no further liability to the FNPF arises.
If you fail to nominate someone to receive your funds in the event of your death, the funds will be transferred to the High Court who will then decide who will receive these funds. As such, to ensure that your funds are paid to the person of your choice, you must formally nominate them at the time you exercise your retirement option.
