Coverage description
A National Council on Compensation Insurance (NCCI) standard form. It removes the partners, officers and others listed in its schedule from the policy: their injuries are not covered, their pay is left out of the premium basis, and the employer repays any benefits the insurer is made to pay them.
Updated
What the form says
Key clauses from the original edition, which has not been revised, quoted as filed.
“The policy does not cover bodily injury to any person described in the Schedule.”
WC 00 03 08
Who is excluded. Only the partners, officers and others entered in the schedule lose coverage. Every other employee stays covered.
“The premium basis for the policy does not include the remuneration of such persons.”
WC 00 03 08
Excluded pay drops out of the premium. The payroll of the excluded persons is not charged, which is the premium side of the exclusion.
“You will reimburse us for any payment we must make because of bodily injury to such persons.”
WC 00 03 08
The employer repays forced payments. If the insurer still has to pay benefits to an excluded person, for example under state law, the employer must pay the insurer back.
