B is correct. Hedge funds look for policies in which the ongoing premium payments to keep the policy active are relatively low, so Feature 2 is correct. Hedge funds also look for life settlements where the surrender value offered to the insured individual is also relatively low and the probability that the designated insured person is likely to die earlier than predicted by standard actuarial methods is relatively high.

A is incorrect because hedge funds look for policies in which the surrender value offered to the insured individual is relatively low (not high) in order to enhance return by purchasing at a lower price.

C is incorrect because hedge funds look for settlements in which the probability that the designated insured person is likely to die earlier than predicted by standard actuarial methods is relatively high. This means the hedge fund’s cash outflows to pay the ongoing premium will be less than predicted, which will enhance return.
