Variable universal life combines two elements: a flexible-premium permanent life insurance policy and an investment portfolio held in sub-accounts chosen by the policyholder. Unlike certain whole life insurance policies, where cash value typically grows at a fixed or guaranteed rate, VUL's cash value depends on the performance of the underlying investments and can rise or fall accordingly.
VUL is one of several types of life insurance, alongside universal life insurance (ULI) and private placement life insurance (PPLI), each with different features, costs and suitability considerations. An authorised insurance broker can explain which structure, if any, may be appropriate for a particular situation.
