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
Health: the largest of the 9 insured health contracts, with KAISER FOUNDATION HEALTH PLAN, INC., covers 236 of 12,423 participants (1.9%) on Schedule A.
Dental: the largest of the 2 insured dental contracts, with CIGNA HEALTH AND LIFE INSURANCE COMPANY, covers 11 of 12,423 participants (under 0.1%) on Schedule A.
Also declared: death benefits.
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.
