This diagram shows aggregate stop-loss claims over a three-month period. The accumulated monthly attachment point, which represents the sum of the monthly attachment points for the completed policy months, increases each month. In the first two months, the accumulated aggregate attachment point is not exceeded. In the third month, it is exceeded when the accumulated three months of claims total $319,000 and the accumulated monthly attachment point is $300,000. The amount over the accumulated attachment point—$19,000—is sent to the employer.
