PERMANENT RULES
DEPARTMENT OF
LABOR AND INDUSTRIES
[Filed November 30, 2017, 9:59 a.m., effective January 1, 2018]
Effective Date of Rule: January 1, 2018.
Purpose: The purpose of this rule adoption is to establish premium rates and experience rating parameters for calendar year 2018. Washington law, RCW 51.16.035, 51.32.073, 51.18.010, and 51.04.020, requires labor and industries 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. Labor and industries is proposing a 2.5 percent overall average decrease to workers' compensation insurance premium rates beginning January 1, 2018, and adjusting each industry risk classification rate to reflect current loss experience.
This rule adoption 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 2018. Classification base rates were amended for updated loss and payroll experience. The department proposes a 2.5 percent overall average premium rate decrease.
The department's decision to decrease overall rates by an overall average of 2.5 percent is intended to ensure adequate premiums to cover expected losses for 2018 claims and to maintain the contingency reserve at adequate levels.
Finally, this rule making provides notice that the director intends to transfer the amount of the accident and medical-aid funds combined that exceed ten percent of funded liabilities as required by RCW 51.44.023.

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 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 $20,112 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 $((2,820)) 2,930 or the total cost of the claim. Here are some examples for these claims:

Note:
The deduction, $((2,820)) 2,930, 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 16-24-014, filed 11/29/16, effective 1/1/17)
WAC 296-17-920 Assessment for supplemental pension fund.
The amount of ((48.0 mils ($0.0480))) 51.5 mils ($0.0515) shall be retained by each employer from the earnings of each worker for each hour or fraction thereof the worker is employed. The amount of money so retained from the employee shall be matched in an equal amount by each employer, except as otherwise provided in these rules, all such moneys shall be remitted to the department on or before the last day of January, April, July, and October of each year for the preceding calendar quarter, provided self-insured employers shall remit to the department as provided under WAC 296-15-229. All such moneys shall be deposited in the supplemental pension fund.
AMENDATORY SECTION (Amending WSR 16-24-014, filed 11/29/16, effective 1/1/17)
WAC 296-17B-540 Determining loss incurred for each claim.
(1) Calculating the initial loss incurred:
For each of your claims, we will multiply the case incurred loss by the appropriate discounted loss development factors to determine the initial loss incurred.
If you have a fatality, we will use three hundred ((sixteen)) thirty-five thousand ((seven hundred)) dollars as the claim's initial incurred loss for the claim, with two hundred ((eighty-three)) ninety-eight thousand ((three)) eight hundred dollars for accident fund incurred loss and ((thirty-three)) thirty-six thousand ((four)) two hundred dollars for the medical aid incurred loss, regardless of the case incurred loss, and before recovery factors if applicable.
(2) Applying the single loss occurrence limit:
The initial loss incurred for a claim will be the amount we use as the loss incurred unless the single loss occurrence limit applies.
The single loss occurrence limit applies when the sum of all initial losses incurred for your claims arising out of a single event is greater than your selected single loss occurrence limit. In that case, each claim's initial loss incurred will be its proportionate share of your single loss occurrence limit.
(3) Applying the expected loss ratio factors:
The preliminary loss incurred for a claim will be the amount of the initial loss incurred, after application of the single loss limit, multiplied by the appropriate expected loss ratio factor. The accident fund and medical aid fund portions of each claim will have separate expected loss ratio factors applied.
