One of the hallmarks of a well-managed portfolio of life settlements is that the premiums required to support the policies are well "optimized." To minimize future cash requirements and maximize returns, the fund manager seeks to pay the minimum premium required to keep a given policy in force at the latest possible time. This is one of the primary reasons why traditional, non-guaranteed universal life policies make up the vast bulk of life settlements: flexible premiums.
Consider, for example, three $1 million policies on the same insured: a current assumption universal life, a universal life with secondary guarantees, and a whole life policy. Each illustrates a level premium to maturity of $50,000 per year.
For many (if not most) guaranteed universal life policies, the optimized premium is $50,000. Although the premium is theoretically "flexible" — in that a premium greater than $50,000 can be applied to the policy — failure to pay the minimum (guaranteed) premium results in a lapse.
