[Filed September 17, 1997, 11:12 a.m.]

Original Notice.

Preproposal statement of inquiry was filed as WSR 97-15-139 and 97-15-140.

Title of Rule: Chapter 296-17 WAC, Manual of rules, classifications, rates, and rating system for workers' compensation insurance.

Purpose: Amend risk classification premium base rates, and experience rating and retrospective rating tables to reflect updated loss experience and provide a 5% overall rate reduction effective January 1, 1998. This proposal specifically amends WAC 296-17-855, 296-17-875, 296-17-880, 296-17-885, 296-17-890, 296-17-895, 296-17-919, 296-17-91901, 296-17-91902, 296-17-91903, 296-17-91904, 296-17-91905, and 296-17-920.

Statutory Authority for Adoption: RCW 51.16.035 Base rates, 51.32.073 Supplemental pension, and 51.04.020(1) General authority.

Statute Being Implemented: RCW 51.16.035 and 51.32.073.

Summary: Proposal establishes premium rates for workers' compensation insurance classifications for calendar year 1998 and modifications to the related experience rating and retrospective rating plans. WAC 296-17-855 Experience modification, 296-17-875 Table I Primary losses for selected claim values, 296-17-880 Table II "B" and "W" values, 296-17-885 Table III Expected loss rates and D ratios, 296-17-890 Table IV Maximum experience modifications, 296-17-895 Base rate table by class of industry, 296-17-919 Retrospective rating plans A, A1, A2, A3, and B, and 296-17-920 Assessment for supplemental pension fund.

Reasons Supporting Proposal: Insurance base rates and experience rating tables are being modified to reflect changes in loss data associated with the classification and rating plan from the previous 1997 rating period. Washington law provides that rates should be adjusted annually to reflect the hazards of each industry and in accordance with the rating plan. Similarly the rating plan is revised to recognize changes within industry groups. A five percent reduction in overall premium rates is also proposed reflecting low medical inflation, reduction of long term disability claims and better than expected performance of state fund investments.

Name of Agency Personnel Responsible for Drafting: Bill White, Bill Vasek and Frank Romero, Tumwater, 902-5014/5015; Implementation: Douglas Connell and Kathy Kimbel, Tumwater, 902-4209/4739; and Enforcement: Kathy Kimbel and Doug Mathers, Tumwater, 902-4209/4750.

Name of Proponent: Department of Labor and Industries, governmental.

Rule is not necessitated by federal law, federal or state court decision.

Explanation of Rule, its Purpose, and Anticipated Effects: The purpose of this proposal is to establish 1998 premium rates and experience rating parameters for calendar year 1998. Washington law (RCW 51.16.035 and 51.32.073) requires the Department of Labor and Industries to adjust rates to ensure solvency of the accident, medical aid and supplemental pension funds. RCW 15.16.035 also provides that premium rates charged to industry vary by degree of hazard. The Department of Labor and Industries is proposing to adjust each industry risk classification to reflect more current loss experience. In addition, the Department of Labor and Industries is proposing an overall reduction in workers' compensation insurance premium rates of five percent beginning January 1, 1998.

Proposal Changes the Following Existing Rules: Overall premium levels will be reduced five percent. Rates for each industry classification will reflect updated loss experience as well as the overall rate reduction. Industries such as vineyards, mechanized logging and bakeries that had improved loss experience will see greater reductions. Other industries such as shipbuilding and coin-operated laundries will see their premium rates increase as a result of worsening loss experience.

No small business economic impact statement has been prepared under chapter 19.85 RCW. RCW 19.85.025(2) exempts rules covered by RCW 34.05.310 (4)(f).

Section 201, chapter 403, Laws of 1995, does not apply to this rule adoption. RCW 34.05.328 (5)(b)(vi) provides an exemption for rules that set rates or fees pursuant to legislative standards. RCW 51.16.035 requires the Department of Labor and Industries to set premium rates according to legislative standards.

Hearing Location: On November 3, 1997, at 10:00 a.m., First Floor Auditorium, Tumwater Labor and Industries Office Building, 7273 Linderson Way S.W., Tumwater, WA; and on November 6, 1997, at 10:00 a.m., Conference Room #4, Spokane Labor and Industries Office Building, 901 North Monroe, Suite 100, Spokane, WA.

Assistance for Persons with Disabilities: Contact Ken Woehl by October 27, 1997, TDD (360) 902-4775, or 902-4776.

Submit Written Comments to: Department of Labor and Industries, Douglas Connell, Assistant Director for Insurance Services, P.O. Box 4100, Olympia, WA, FAX (360) 902-4729, by October 31, 1997.

Date of Intended Adoption: November 27, 1997.

AMENDATORY SECTION (Amending WSR 96-24-063, filed 11/29/96, effective 1/1/97)

WAC 296-17-855 Experience modification. The basis of the experience modification shall be a comparison of the actual losses charged to an employer during the experience period with the losses which would be expected for an average employer reporting the same exposures in each classification. The comparison shall contain actuarial refinements designed to mitigate the effects of losses which may be considered catastrophic or of doubtful statistical significance, due consideration being given to the volume of the employer's experience. Except for those employers who qualify for an adjusted experience modification as specified in WAC 296-17-860 or 296-17-865, the experience modification shall be calculated from the formula:

Ap + WAe + (1-W) Ee + B

modification =

E + B

The components Ap, WAe, and (1-W) Ee are values which shall be charged against an employer's experience record. The component, E, shall be the expected value of these charges for an average employer reporting the same exposures in each classification. The meaning and function of each symbol in the formula is specified below.

"Ap" signifies "primary actual losses." For each claim the primary actual loss is defined as that portion of the claim which is considered completely rateable for all employers and which is to enter the experience modification calculation at its full value. For each claim in excess of (($10,102)) $10,195 the primary actual loss shall be determined from the formula:

((25,256)) 25,487

primary loss = x total loss

Total loss + ((15,154)) 15,292

Primary actual losses for selected claim values are shown in Table I. For each claim less than (($10,102)) $10,195 the full value of the claim shall be considered a primary loss.

"Ae" signifies "excess actual losses." For each claim the excess actual loss is defined as that portion of the claim which is not considered completely rateable for all employers. The excess actual loss for each claim shall be determined by subtracting the primary loss from the total loss.

"W" signifies "W value." For each employer, the W value determines the portion of the actual excess losses which shall be included in the calculation of his experience modification, due consideration being given to the volume of his experience. This amount is represented by the symbol "WAe" in the experience modification formula. W values are set forth in Table II.

"E" signifies "expected losses." An employer's expected losses shall be determined by multiplying his reported exposure in each classification during the experience period by the classification expected loss rate. Expected loss rates are set forth in Table III.

"Ee" signifies "expected excess losses." Expected losses in each classification shall be multiplied by the classification "D-Ratio" to obtain "expected primary losses." Expected excess losses shall then be calculated by subtracting expected primary losses from expected total losses. Each employer shall have a statistical charge included in the calculation of his experience modification, said charge to be actuarially equivalent to the amount forgiven an average employer because of the exclusion of a portion of his excess actual losses. This charge is represented by "(1-W) Ee" in the experience modification formula. D-Ratios are set forth in Table III.

"B" signifies "B value" or "ballast." In order to limit the effect of a single severe accident on the modification of a small employer, a stabilizing element (B value) shall be added to both actual and expected losses. B values are set forth in Table II.
