In the case of traditional life insurance, the policyholder is usually offered a guaranteed sum assured. In addition, non-guaranteed bonuses in the form of a share in the profits of the Company may also be offered depending on whether the policy is a participating policy or not. The policyholder has no say in the choice of investments, which are decided by the company on his behalf. The premium amounts are usually fixed at the outset and the same quantum of premium needs to be paid throughout the term of the policy. The main difference is in the flexibility in the choice of investments. In the case of unit-linked life insurance, the insurance company would usually offer a choice of different funds (say, with a differential mix of bond and equity investments) in which the policyholder can opt to invest his contributions. These funds differ by virtue of their risk exposure and their appreciation potential. The policyholder can decide which funds his contributions need to be invested in and in what proportion. Therefore, the returns under the policy are dependent on the investment choice made by the policyholder. The policyholder can also opt to invest top-up contributions over and above the regular contributions at any time and to switch his investment pattern at any time during the term of the policy.
