How this plan is funded
Fully insured as reported
The filing reports medical coverage through an insurance contract on Schedule A, and no money paid for benefits by the plan itself.
Benefits declared on this filing
2 contracts on this filing do not say which benefits they cover, so a line above may be insured by one of them.
Also declared: death benefits, other welfare.
Declared benefits are the plan’s own line 8b codes on Form 5500. “Not on Schedule A” means no insured contract for that line appears on this filing. That usually means the benefit is self-funded, or it sits under a different plan number.
Where a line has more than one insured contract, the carrier and the covered figure are the largest contract's by premium. The contracts are not added up: a pharmacy carve-out and the medical carrier beside it cover the same people.
Persons covered is the count the carrier filed for that policy at the end of its policy year, and it can include dependents. Participants is the plan's own count at the start of its plan year. The two count different people, so a covered figure can be larger.
Plan brief
Schedule A lists 6 insured contracts covering health, vision, life and disability; the largest, with GROUP HEALTH COOPERATIVE OF SOUTH CENTRAL WISCONSIN, covers 1,003 people.
The filing declares health, vision, life, disability and dental. Dental appears with no insured contract on Schedule A. That coverage may be self-funded, placed with a carrier that is not on this filing, or written on one of the 2 contracts here that do not say what they cover.
Reported premium across the insured contracts is $11,342,690, with $27,627 in disclosed broker commissions — about 0.2% of premium.
The health contract's policy period ended in December, while at least one ancillary line's policy period ended in September. The plan is on a split renewal cycle.
MARSH AND MCLENNAN AGENCY, LLC is the broker of record on 1 of the 6 contracts; the rest name a different broker or none.
