Flow of new members into the group
Another important group underwriting requirement is that a sufficient number of new members enter the group periodically. Ideally, underwriters seek a steady flow of young. New members to replace those members who leave the group. A steady flow of new members into the group means that both the group’s size and its age distribution remain stable. If a group did not add young, new members for a number of years, then the increasing age of the group’s original members would adversely affect the group’s age distribution , and the group’s loss rate and premium rate would increase as a result. But if young, new members are continually joining the group, the age distribution of the group should remain more stable, as should the expected loss rate.
