Effective Date of Rule: Thirty-one days after filing.

     Purpose: This rule will amend the tables of classification base premium rates, experience rating plan parameters, experience modification factor calculation limitations and retrospective rating plan size groupings for the workers' compensation insurance program for calendar year 2012. Classification base rates are being amended to base the rates on updated loss and payroll experience, and to result in no overall increase in premium rates for 2012. This rule will add language to reflect the new stay-at-work program, created by EHB 2123 adopted by the 2011 legislature and signed by the governor. This rule will repeal rules related to the expired farm internship program.

AMENDATORY SECTION(Amending WSR 05-12-031, filed 5/24/05, effective 7/1/05)

WAC 296-17-31024   Classification premium rates.   (((1))) How do you determine what rate to charge me? You are charged premiums using base rates for each of your risk classifications ((has corresponding base rates. The base rates assigned to your business will depend on the basic classification(s) assigned to your business.

     (2) What do you mean by a base rate?

     The base rate is a comparison of losses (claims) and exposure to produce a cost per unit of exposure. The base rate is an unmodified rate that all employers with an experience factor of 1.000 will pay in a specific classification.

     (3) Do all employers in the same classification pay the base rate?

     In practice, only a few employers pay the base rate. Most employers pay rates that are adjusted to take into account the employer's claims and premium reporting experience. We refer to those modified rates as experience rates. Your experience rate can be higher or lower than the base rate. This means that employers with fewer than expected losses will pay less than employers in the same classification who have more than expected losses. Experience rating encourages strong safety and accident prevention programs. Details of how experience rating affects your premium are found in WAC 296-17-850 through 296-17-890. Your account manager can also answer questions about your individual experience factor. The name and phone number of your account manager can be found on your quarterly premium report or your annual rate notice. For your convenience you can call us at 360-902-4817 and we will put you in contact with your assigned account manager)). These premiums include rates for each of the four different premiums you are required to pay: Accident fund premiums, medical aid fund premiums, stay-at-work program premiums, and supplemental pension fund premiums. Your premiums for each classification are determined by multiplying your experience factor by the sum of the accident fund, medical aid fund and stay-at-work program base rates for that class, and then adding the supplemental pension fund rate.

EXPERIENCE MODIFICATION FACTOR	=	(Credible Actual Primary Loss + Credible Actual Excess Loss)/Expected Loss
Where
Credible Actual Primary Loss	=	Actual Primary Loss x Primary Credibility
	+	Expected Primary Loss x (100% -Primary Credibility)
Credible Actual Excess Loss	=	Actual Excess Loss x Excess Credibility
	+	Expected Excess Loss x (100% - Excess Credibility)

     The meaning and function of each term in the formula is specified below.

     For each claim, the actual primary loss is the first dollar portion of the claim costs, which has been shown in actuarial studies, to have the greater credibility in predicting future experience. These amounts are summed over all claims. For each claim in excess of $20,112 the actual primary loss shall be determined from the formula:

ACTUAL PRIMARY LOSS	=	50,280	x total loss
		(Total loss + 30,168)

     For each claim, less than $20,112 the full value of the claim shall be considered a primary loss.

     For each claim, the excess actual loss is the remaining portion of the claim costs, which have been shown in actuarial studies to have less credibility in predicting future experience. The excess actual loss for each claim shall be determined by subtracting the primary loss from the total loss. These amounts are summed over all claims.

     For any claim without disability benefits (time loss, partial permanent disability, total permanent disability or death) either actually paid or estimated to be paid, the total actual losses for calculating the primary loss and excess loss shall first be reduced by the lesser of $((2,120)) 2,330 or the total cost of the claim. Here are some examples for these claims:

Total Loss		Type of Claim		Total Loss (after deduction)		Primary Loss		Excess Loss
200		Medical Only		0		0		0
2,500		Medical Only		((380)) 170		((380)) 170		0
2,500		Time Loss		2,500		2,500		0
25,000		Medical Only		((22,880)) 22,670		((21,686)) 21,572		((1,194)) 1,098
25,000		Time Loss		25,000		22,785		2,215
100,000		PPD		100,000		38,627		61,373
2,000,000		TPD Pension		((233,084)) 253,784		((44,518)) 44,938		((188,566)) 208,846

Note:

The deduction, $((2,120)) 2,330, is twice the average case incurred cost of these types of claims occurring during the three-year period used for experience rating. On average this results in reducing the average actual loss about seventy percent for these types of claims adjusted. This is done to help make the transition between the two different experience rating methods better by helping make the change in experience factor reasonable for small changes to the actual losses. The $2,000,000 loss is limited by the Maximum Claim Value before the reduction of $((2,120)) 2,330 is applied.

     For each employer, the primary credibility and the excess credibility determines the percentage weight given to the corresponding actual primary losses and the actual excess losses, included in the calculation of the experience modification, based on the volume of expected losses. Primary credibility and excess credibility values are set forth in Table II.

     An employer's expected losses shall be determined by summing the expected loss for each of the three years of the experience period, which are calculated by multiplying the reported exposure in each classification during the year by the corresponding classification expected loss rate and rounding the result to the nearest cent. Classification expected loss rates by year are set forth in Table III.

     Expected losses in each classification shall be multiplied by the classification "Primary-Ratio" to obtain "expected primary losses" which shall be rounded to the nearest cent. Expected excess losses shall then be calculated by subtracting expected primary losses from expected total losses rounded to the nearest cent. Primary-Ratios are also set forth in Table III.

     (a) Accident and medical aid payments; and

     (b) Pension reserve amounts paid by the accident fund; and

     (c) Accident and medical aid benefits or payments that are scheduled to be paid; and

     (d) Reserve for other accident and medical aid benefits accessible by the worker while the claim is closed.

     The actual losses for claims that are open may, in addition, also include a reserve for future payments. Actual losses do not include wage subsidies or reimbursements paid by the stay-at-work program.

     (2) Valuation date. The valuation date shall be June 1, seven months immediately preceding the effective date of premium rates.

     (3) Retroactive adjustments - Revision of losses between valuation dates. No claim value shall be revised between valuation dates and no retroactive adjustment of an experience modification shall be made because of disputation concerning the judgment of the claims examiner or because of subsequent developments except as specifically provided in the following cases:

     (a) In cases where loss values are included or excluded through mistake other than error of judgment.

     (b) In cases where a third party recovery is made, subject to subsection (5)(a) of this section.

     (c) In cases where the claim qualifies as a second injury claim under the provisions of RCW 51.16.120.

     (d) In cases where a claim, which was previously evaluated as a compensable claim, is closed and is determined to be noncompensable (ineligible for benefits other than medical treatment).

     (e) In cases where a claim is closed and is determined to be ineligible for any benefits.

     In the above specified cases retroactive adjustment of the experience modification shall be made for each rating in which the claim was included. Retroactive adjustments will not be made for rating periods more than ten years prior to the date on which the claim status was changed.

     (4) Average death value. Each fatality occurring to a worker included within the mandatory or elective coverage of Title 51 RCW shall be assigned the "average death value." The "average death value" shall be the average incurred cost for all such fatalities occurring during the experience period. The average death value is set forth in WAC 296-17-880 (Table II).

     (5) Third-party recovery - Effect on experience modification.

     (a) For claims with injury dates prior to July 1, 1994, a potential claim cost recovery from action against a third party, either by the injured worker or by the department, shall not be considered in the evaluation of actual losses until such time as the third-party action has been completed. If a third-party recovery is made after a claim had previously been used in an experience modification calculation, the experience modification shall be retroactively adjusted. The department shall compute a percentage recovery by dividing the current valuation of the claim into the amount recovered or recoverable as of the recovery date, and shall reduce both primary and excess losses previously used in the experience modification calculation by that percentage.

     (b) For claims with injury dates on or after July 1, 1994, if the department determines that there is a reasonable potential of recovery from an action against a third party, both primary and excess values of the claim shall be reduced by fifty percent for purposes of experience modification calculation, until such time as the third-party action has been completed. This calculation shall not be retroactively adjusted, regardless of the final outcome of the third-party action. After a third-party recovery is made, the actual percentage recovery shall be applied to future experience modification calculations.

     (c) For third-party actions completed before July 1, 1996, the claim shall be credited with the department's net share of the recovery, after deducting attorney fees and costs. For third-party actions completed on or after July 1, 1996, the claim shall be credited with the department's gross share of the recovery, before deducting attorney fees and costs.

     (d) Definitions:

     (i) As used in this section, "recovery date" means the date the money is received at the department or the date the order confirming the distribution of the recovery becomes final, whichever comes first.

     (ii) As used in this section, "recoverable" means any amount due as of the recovery date and/or any amount available to offset case reserved future benefits.

     (6) Second injury claims. The primary and excess values of any claim which becomes eligible for second injury relief under the provisions of RCW 51.16.120, as now or hereafter amended, shall be reduced by the percentage of relief granted.

     (7) Occupational disease claims. When a claim results from an employee's exposure to an occupational disease hazard, the "date of injury," for the purpose of experience rating, will be the date the disability was diagnosed and that gave rise to the filing of a claim for benefits. The cost of any occupational disease claim, paid from the accident fund and medical aid fund and arising from exposure to the disease hazard under two or more employers, shall be prorated to each period of employment involving exposure to the hazard. Each insured employer who had employed the claimant during the experience period, and for at least ten percent of the claimant's exposure to the hazard, shall be charged for his/her share of the claim based upon the prorated costs.

     (8) Maximum claim value. No claim shall enter an employer's experience record at a value greater than the "maximum claim value." The maximum claim value is set forth in WAC 296-17-880 (Table II).

     (9) Catastrophic losses. Whenever a single accident results in the deaths or total permanent disability of three or more workers employed by the same employer, costs charged to the employer's experience shall be limited as required by RCW 51.16.130.

     (10) Acts of terrorism. Whenever any worker insured with the state fund sustains an injury or occupational disease as a result of an incident certified to be an act of terrorism under the U.S. Terrorism Risk Insurance Act of 2002, the costs of the resulting claim shall be excluded from the experience rating computation of the worker's employer.

     (11) Claims filed by preferred workers. The costs of subsequent claims filed by certified preferred workers will not be included in experience calculations, as provided in WAC 296-16-010.

     (12) Life and rescue phase of emergencies: This provision applies to "emergency workers" of nongovernmental employers assigned to report in classification 7205 (WAC 296-17A-7205) who assist in a life and rescue phase of a state or local emergency (disaster). The life and rescue phase of an emergency is defined in RCW 51.16.130(3) as being the first seventy-two hours after a natural or man-made disaster has occurred. For an employer to qualify for this special experience rating relief, a state or local official such as, but not limited to, the governor; a county executive; a mayor; a fire marshal; a sheriff or police chief must declare an emergency and must request help from private sector employers to assist in locating and rescuing survivors. This special relief is only applicable to nongovernmental employers during this initial seventy-two hour phase of the declared emergency unless the emergency has been extended by the official who declared the emergency. The cost of injuries or occupational disease claims filed by employees of nongovernmental employers assisting in the life and rescue phase of a declared emergency will not be charged to the experience record of the nongovernmental state fund employer.
