Each individual and small group filing must include the following information and documents:

(b) The number of subscribers by family size, or covered persons for the plans included in the filing.

(d) An estimate of the adjusted earned premium for each month or quarter of the experience period and prior two periods for the plans included in the filing.
(e) Claims data for each month or quarter of the experience period and the prior two periods.

The specific data elements included in the filing must be consistent with the carrier's rate-making methodology.
(f) Documentation and justification of any adjustments made to the experience data.
(g) Documentation and justification of the factors and methods used to forecast incurred claims.
(2) An actuarially sound estimate of prudently incurred expenses. Experience data, assumptions, and justifications must be provided by the carrier as follows:

(i) An expense breakdown at least as detailed as the annual statement schedule "Underwriting and Investment Exhibit, Part 3, Analysis of Expenses" as revised from time to time;
(ii) The allocation and assignment methodology used in (a)(i) of this subsection may be based on readily available data and easily applied calculations;
(b) Identification of any extraordinary experience period expenses; and
(c) Documentation and justification of the assignment or allocation of expenses to the plans included in the filing; and

The carrier must include documentation and justification of forecasted investment earnings identified in dollars, and as a percentage of total premiums and the amount credited to the plans included in the filing.
(5) Adjustment of the base rate. Experience data, assumptions, justifications, and methodology descriptions must be provided and must include:

(b) Justifications, supported by data if appropriate, of any other factors or circumstances used to adjust the base rates; and
(c) Description of the methodology used to adjust the base rate to obtain the premium rate for a specific individual or group, which is detailed enough to allow the commissioner to replicate the calculation of premium rates if given the necessary data.
(6) Actuarial certification. Certification by an actuary, as required by RCW 48.44.017(2), 48.44.023(3), 48.46.062(2) and 48.46.066(3).
