How this plan is funded
Both, as reported
The medical insurance contracts on the filing cover fewer than half the people in the plan, so the rest is paid another way.
A stop-loss policy appears on a Form 5500 only when the plan itself is the beneficiary, or the premiums are paid from plan money. Many employers buy stop-loss and never report it here. So a plan with no stop-loss on its filing may still have it.
Benefits declared on this filing
Health: the largest of the 4 insured health contracts, with KAISER FOUNDATION HEALTH PLAN OF THE MID-ATLANTIC STATES, INC., covers 94 of 1,693 participants (5.6%) on Schedule A.
4 contracts on this filing do not say which benefits they cover, so a line above may be insured by one of them.
Also declared: prepaid legal, other welfare, 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.
Plan brief
Schedule A lists 12 insured contracts covering health, vision, life, disability and stop-loss; the largest, with AETNA LIFE INSURANCE COMPANY, covers 976 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 4 contracts here that do not say what they cover.
The medical plan carries stop-loss coverage: the filing reports the plan paying its own health claims, with insured protection against large ones.
Reported premium across the insured contracts is $5,625,843, with $330,750 in disclosed broker commissions — about 5.9% of premium.
The most recent policy period ended in December, and the plan year ends December 31. Group contracts typically renew on that annual cycle.
