A. An insurer filing which refers to or incorporates a rating organization's reference filing of prospective loss costs shall include the following:
(1) Reference filing adoption form as set forth in Regulation .08 of this chapter, or the NAIC Loss Cost Filing Documents titled "Other than Workers' Compensation", "For Workers' Compensation", and "NAIC Expense Constant Supplement";
(2) Summary of supporting information as set forth in Regulation .08 of this chapter; and
(3) Expense constant supplement as set forth in Regulation .08 of this chapter if expense constants are utilized.
B. To the extent that an insurer's final rates are determined solely by applying its loss cost adjustments, as presented in the reference filing adoption form, to the prospective loss costs contained in a rating organization's reference filing and printed in the rating organization's rating manual, the insurer need not develop or file its final rate pages with the Commissioner. If an insurer chooses to print and distribute final rate pages for its own use, based solely upon the application of its filed loss cost adjustments to a rating organization's prospective loss costs, the insurer need not file those pages with the Commissioner. If the rating organization does not print the loss costs in its rating manual, the insurer must submit its rates to the Commissioner.
C. With the initial prospective loss cost reference filing, rating organizations will no longer develop or file minimum premiums. If an insurer wishes to use minimum premiums it shall file the minimum premiums it will use.
