Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The proposed rule 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 2026. Classification base rates were updated to align with expected losses. L&I proposes a 4.9 percent overall average premium rate change.

Amending WAC 296-17-855 Experience modification, 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-540 Determining loss incurred for each claim, and 296-17B-900 Retrospective rating plans standard premium size ranges; and repealing WAC 296-17-945 Classification 1408 (Passenger transportation network companies rate).

Reasons Supporting Proposal: Washington law provides that rates should be adjusted annually to reflect the hazards of each industry and in accordance with recognized workers' compensation insurance principles.

L&I is proposing an overall average rate increase of 4.9 percent to ensure premiums cover most of the expected costs of 2026 workers' compensation claims. This increase is less than the indicated break-even rate and consistent with the L&I's rate-making principle of keeping rates steady and predictable. This rate increase is required to partially account for five consecutive years of higher-than-normal increases in the state's average wage. In addition, the increase enables L&I to maintain working capital in the supplemental pension fund which pays for annual cost-of-living adjustments (COLAs) for pensions. L&I is able to minimize the increase for this upcoming year due to accumulated investment earnings that benefit the workers' compensation contingency reserve.

The proposed rule also repeals WAC 296-17-945 Classification 1408 (Passenger transportation network companies rate) and adds that classification rate into the base rate rule WAC 296-17-895 Base rates.

Lastly, this proposal 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.

Statutory Authority for Adoption: RCW 51.16.035 (base rates), 51.32.073 (supplemental pension), 51.18.010 (retrospective rating), and 51.04.020(1) (general authority).

Statute Being Implemented: RCW 51.16.035, 51.32.073, and 51.18.010.

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

Name of Proponent: L&I, governmental.

Name of Agency Personnel Responsible for Drafting: Jo Anne Attwood, Tumwater, 360-902-4777; Implementation: Michelle O'Brien, Tumwater, 360-902-4826; and Enforcement: Brenda Heilman, Tumwater, 360-902-6369.

A school district fiscal impact statement is not required under RCW 28A.305.135.

A cost-benefit analysis is not required under RCW 34.05.328. A cost-benefit analysis is not required per RCW 34.05.328 (5)(b)(vi), as the proposed rules are adjusting rates pursuant to legislative standards.

This rule proposal, or portions of the proposal, is exempt from requirements of the Regulatory Fairness Act because the proposal:

Is exempt under RCW 19.85.025(3) as the rule content is explicitly and specifically dictated by statute; and rules set or adjust fees under the authority of RCW 19.02.075 or that set or adjust fees or rates pursuant to legislative standards, including fees set or adjusted under the authority of RCW 19.80.045.

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 (($25,750))$28,180 the actual primary loss shall be determined from the formula:

Primary Loss	=	((64,380))70,460	x Total Loss
		(Total Loss + ((38,630))42,280)

For each claim, less than (($25,750))$28,180 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 (($3,930))$4,100 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
2,000	Medical Only	0	0	0

5,000	Timeloss	5,000	5,000	0

500,000	TPD Pension	398,730	63,705	335,025
2,000,000	TPD Pension	398,730	63,705	335,025

Note:

The deduction, (($3,930))$4,100, 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 70 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 24-24-046, filed 11/26/24, effective 1/1/25)

WAC 296-17B-540Determining 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 (($576,200))$591,600 as the claim's initial incurred loss for the claim, with (($537,700))$549,200 for accident fund incurred loss and (($38,500))$42,400 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.
