France is a daycare owner who has an employer group benefits plan in place for her employees. During her annual renewal meeting with her insurance agent, she is told that the plan’s rates are increasing by a surprisingly large percentage. Her agent explains that although most of her staff are young females in their 20s, the claims experience is higher than the industry norm. What amendment to the group plan could France’s agent suggest to help control the cost?
