Coverage description

A National Council on Compensation Insurance (NCCI) standard form. It adds an audit noncompliance charge to the policy's audit condition, so the insurer can raise the premium when you refuse a premium audit or do not return requested audit information.

Updated

What the form says

Key clauses from the original edition, which has not been revised, quoted as filed.

“do not provide audit information as requested, we may apply an Audit Noncompliance Charge”

WC 00 04 24

What triggers the charge. Refusing the insurer access to records that relate to the policy, or not returning the audit information it asks for, lets the insurer apply the charge.

“The method for determining the Audit Noncompliance Charge by state, where applicable, is shown in the Schedule below.”

WC 00 04 24

How the charge is set. The schedule lists each state with the basis of the charge and a maximum multiplier, so the amount comes from each state's approved rule rather than a single figure in the form.

“after we have applied an Audit Noncompliance Charge, we will revise your premium in accordance with our manuals”

WC 00 04 24

How the charge is reversed. If you allow the audit after the charge is applied, the insurer recalculates the final premium from your records under its rating manuals.

“failure to cooperate with this policy provision may affect your eligibility for coverage”

WC 00 04 24

What it means in an assigned risk plan. For a policy written through a state assigned risk plan, refusing the audit can also affect your eligibility for that coverage, in addition to the possible cancellation the endorsement mentions.

How the form has changed

Filed copies carry the original 01-2017 edition, with no revision letter.
