    3. PCRB Rating Values – All parameters filed by the PCRB and approved by the Insurance Commissioner, and which are used either mandatorily or by option of carriers for purposes of pricing workers compensation and employers liability coverages. Such PCRB rating values include PCRB Loss Costs, experience rating plan values such as Expected Loss Cost Factors, Credibility, Maximum Value of One Accident, and Credibility Weighted Maximum Value Charge, retrospective rating plan values such as the Table of Expected Loss Ranges, Excess Loss Pure Premium Factors, Retrospective Pure Premium Development Factors, and expense parameters applicable to U.S.L.&H.W. coverages such as Premium Discounts, Expected Loss Ratio, Expense Ratios, Tax Multipliers and Loss Conversion Factors.
    4. Carrier Rate – The amount per unit of exposure which an insurance carrier charges for workers compensation and employers liability insurance.
    5. Carrier Rating Values – All parameters used by carriers for purposes of pricing workers compensation and employers liability insurance coverages. Such parameters may be either PCRB Rating Values adopted by a carrier for its own use or values independently determined by a carrier.
    6. Loss Cost – Dollar amounts per unit of exposure attributable to the payment of losses under workers compensation and employers liability coverages. Loss Costs may be developed either by the PCRB based on the aggregate experience of all PCRB members or may be established by individual carriers based on their own supporting information.

    8. Rating Value – A parameter or number used in pricing workers compensation or employers liability insurance coverages. Rating Values may be established by the PCRB or by individual carriers. Where individual carriers have stablished Rating Values different from those of the PCRB, the carrier’s values supersede those of the PCRB for purposes of that insurer’s policies.
    9. Rating Effective Date (RED) is the earliest date that a specific experience rating or merit rating adjustment is applied to a policy.
