(1) All policy forms issued or delivered on or after January 1, 1990, and before July 1, 1992, as well as any future rate adjustments to such forms, must demonstrate compliance with the loss ratio requirements of WAC 284-66-200 and policy reserve requirements of WAC 284-66-210, unless the forms meet the standards of WAC 284-66-063 and 284-66-203. All filings of rate adjustments must be accompanied by the proposed rate schedule and an actuarial memorandum completed and signed by a qualified actuary as defined in WAC 284-05-060. In addition to the actuarial memorandum, the following supporting documentation must be submitted to demonstrate to the satisfaction of the commissioner that rates are not excessive, inadequate, or unfairly discriminatory and otherwise comply with the requirements of this chapter. If any of the items listed below are inappropriate due to the pricing methodology used by the pricing actuary, the commissioner may waive the requirements upon request of the issuer.

(a) Filings of issue age level premium rates must be accompanied by the following:

(i) Anticipated loss ratios stated on a policy year basis for the period for which the policy is rated. Filings of future rate adjustments must contain the actual policy year loss ratios experienced since inception;

(ii) Anticipated total termination rates on a policy year basis for the period for which the policy is rated. The termination rates should be stated as a percentage and the source of the mortality assumption must be specified. Filings of future rate adjustments must include the actual total termination rates stated on a policy year basis since inception;

(iii) Expense assumptions including fixed and percentage expenses for acquisition and maintenance costs;

(iv) Schedule of total compensation payable to insurance producers and other producers as a percentage of premium, if any;

(v) Specimen copy of the compensation agreements or contracts between the issuer and any insurance producers, or others whose compensation is based in whole or in part on the sale of medicare supplement insurance policies, the agreements demonstrating compliance with WAC 284-66-350 (where appropriate);

(vi) Other data necessary in the reasonable opinion of the commissioner to substantiate the filing.

(b) Filings of community rated forms must be accompanied by the following:

(i) Anticipated loss ratio for the accounting period for which the policy is rated. The duration of the accounting period must be stated in the filing, established based on the judgment of the pricing actuary, and must be reasonable in the opinion of the commissioner. Filings for rate adjustment must demonstrate that the actual loss ratios experienced during the three most recent accounting periods, on an aggregated basis, have been equal to or greater than the loss ratios required by WAC 284-66-200.

(ii) Expense assumptions including fixed and percentage expenses for acquisition and maintenance costs;

(iii) Schedule of total compensation payable to insurance producers and other producers as a percentage of premium, if any;

(iv) Specimen copy of the compensation agreements or contracts between the insurer and any insurance producers or others whose compensation is based in whole or in part on the sale of medicare supplement insurance policies, the agreements demonstrating compliance with WAC 284-66-350 (where appropriate);

(v) Other data necessary in the reasonable opinion of the commissioner to substantiate the filing.

(2) Every issuer must make premium adjustments that are necessary to produce an expected loss ratio under the policy that will conform with the minimum loss ratio standards of WAC 284-66-200.

(3) No premium adjustment that would modify the loss ratio experience under the policy, other than the adjustments described in this section, may be made with respect to a policy at any time other than upon its renewal or anniversary date.

(4) Premium refunds or premium credits must be made to the premium payer no later than upon renewal if a credit is given, or within sixty days of the renewal or anniversary date if a refund is provided.

(5) For purposes of rate making and requests for rate increases, all individual medicare supplement policy forms of an issuer are considered "similar policy forms" including forms no longer being marketed.
