Subject of Possible Rule Making: Labor and industries is considering making changes to existing rules applicable to the retrospective rating program codified in chapter 296-17 WAC. Possible rule changes would better explain how retrospective rating adjustments are calculated and allow the department to use multiple loss development factors in adjustment calculations for nonpension claims.

Statutes Authorizing the Agency to Adopt Rules on this Subject: RCW 51.18.010, 51.16.035.

Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: Current rules limit the department to using a single loss development factor for nonpension claims when calculating retrospective rating adjustments. Since 2006, the department has been using multiple loss development factors in calculating base rates, and the department is considering expanding the practice to retrospective rating adjustment calculations to improve the accuracy of adjustment calculations. Also employers and organizations that participate in the retrospective rating program have asked labor and industries to clarify certain existing retrospective rating program rules described above. Subject rules are needed to administer the retrospective rating program authorized by RCW 51.18.010.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: None.

Process for Developing New Rule: Labor and industries will work directly with the business community that participates in retrospective rating to develop changes to the retrospective rating program rules. This will include input from the retrospective rating advisory committee and the workers' compensation advisory committee. As rule ideas are developed they will be posted to the labor and industries web site and can be accessed at the retro web site or they can contact Mark Matthies at (360) 902-4838 to receive [a] printed copy. Meetings will also be posted on the web site. Labor and industries may also use targeted mailings to solicit input and may hold informal public meetings.

Interested parties can participate in the decision to adopt the new rule and formulation of the proposed rule before publication. Parties interested in the development of the rules can view the draft ideas at the retro web site or they may contact Mark Matthies at (360) 902-4838 to receive a printed copy. They can participate in the rule development process by attending the retro advisory committee meeting or by sending written comments to Retrospective Rating Program, P.O. Box 44180, Olympia, WA 98504-4180. Comments may be faxed to (360) 902-4258 or sent by e-mail to
