PERMANENT RULES
DEPARTMENT OF
LABOR AND INDUSTRIES
[Filed November 30, 2021, 8:24 a.m., effective January 1, 2022]
Effective Date of Rule: January 1, 2022.
Purpose: The purpose of this rule adoption is to establish premium rates and experience rating parameters for calendar year 2022. Washington law (RCW 51.16.035, 51.32.073, 51.18.010, and 51.04.020) requires the department of labor and industries (L&I) to adjust rates to ensure solvency of the accident, medical aid, and supplemental pension funds. RCW 51.16.035 also provides that premium rates vary by industry and degree of hazard. L&I is proposing a 3.1 percent overall average premium rate change to workers' compensation insurance premium rates beginning January 1, 2022, and adjusting each industry risk classification rate to align with expected losses.
This adoption amends the tables of classification base premium rates, experience rating plan parameters, and experience modification factor calculation limitations for the workers' compensation insurance program for calendar year 2022. Classification base rates were amended for updated loss and payroll experience.
This adoption is an attempt to minimize the economic burden on Washington employers who continue to deal with uncertainties associated with the pandemic and the global economy by adopting an overall average rate increase of 3.1 percent to ensure adequate premiums to cover expected losses for 2022 claims. This increase is far below the indicated break-even rate. This average rate increase is required to address a projected shortfall in the supplemental pension fund (a "pay as you go" fund) that pays for cost of living adjustments for all pensions. L&I is able to hold rates down for this upcoming year as a result of an ongoing effort to gradually increase the system's contingency reserve (surplus).
This adoption also amends the experience rating and retrospective rating rules (WAC 296-17-870 Evaluation of actual losses and 296-17B-530 Determining case incurred losses) to explain that all accepted claim losses resulting from a public health emergency will not be included in the determination of an employer's experience modification factor or in an employer's retrospective rating adjustment calculation. An employer will not lose their claim free discount as a result of an allowed public health emergency injury claim.
In addition, this adoption repeals WAC 296-17-89509 Classification 2103 fulfillment centers rate and adds that classification rate into the base rate rule WAC 296-17-895 Base rates.
Lastly, this adoption is also notice that the director intends to transfer the amount of the accident and medical-aid funds combined that exceed 10 percent of funded liabilities as required by RCW 51.44.023.
Citation of Rules Affected by this Order: Repealing WAC 296-17-89509 Classification 2103; and amending WAC 296-17-855 Experience modification, 296-17-870 Evaluation of actual losses, 296-17-875 Table I, 296-17-880 Table II, 296-17-885 Table III, 296-17-890 Table IV, 296-17-895 Industrial insurance accident fund base rates, stay at work and medical aid base rates by class of industry, 296-17-89502 Industrial insurance accident fund, stay at work, medical aid and supplemental pension rates by class of industry for nonhourly rated classifications, 296-17-89507 Horse racing rates, 296-17-89508 Farm internship program industrial insurance, accident fund, stay at work fund, medical aid fund, and supplemental pension by class, 296-17-920 Assessment for supplemental pension fund, 296-17B-530 Determining case incurred losses, and 296-17B-540 Determining loss incurred for each claim.

WAC 296-17-855Experience 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 expected losses for an average employer reporting the same exposures in each classification. The comparison shall contain actuarial refinements designed to weigh the extent to which the actual experience is credible, 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 factor shall be calculated from the formula:
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 (($20,743))$21,280 the actual primary loss shall be determined from the formula:
Primary Loss
=
((51,857))53,210
x Total Loss
(Total Loss + ((31,114))31,930)
For each claim, less than (($20,743))$21,280 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 (($3,340))$3,450 or the total cost of the claim. Here are some examples for these claims:

Note:
The deduction, (($3,340))$3,450, 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.
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.
AMENDATORY SECTION(Amending WSR 20-24-094, filed 11/30/20, effective 1/1/21)
WAC 296-17-870Evaluation of actual losses.
(1) Except as provided in subsections (3) through (13) of this section, the actual losses for claims with a date of injury during the experience period will be evaluated on the "valuation date." Losses on claims occurring outside the experience period will not be included. The actual losses for closed claims must include:
(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," solely for the purpose of experience rating, will be the date the claim for benefits was received by the department. 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 296-16-150.
(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.
(13) ((2019 Coronavirus (COVID-19)))Public health emergency claims: All accepted ((COVID-19)) claim losses resulting from a public health emergency will not be included in the determination of an employer's experience modification factor. An employer will not lose their claim free discount as a result of an allowed ((COVID-19)) claim caused by a public health emergency during a declared public health emergency.
