Experience-based assumptions are those associated specifically with the members being insured. Experience-based assumptions can reflect MutualOne's experience in total, a specific block of business or a particular plan sponsor. Our key rating factors are industry (blue-collar vs. white-collar), region and group size or case size (for our small group business). When rating a particular group, besides recent claims cost experience, demographics are most essential (gender, age, industry). It is also important to note whether the plan is contributory or non-contributory and to note the percentage of eligible group members participating. Plans not meeting minimum contribution/participation levels (varying by group size) will not be underwritten or will receive material loads for antiselection.
