Requiring that experience-rated group disability income insurers include all applicable rating factors and credibility formulas in rate manual filings with the insurance commissioner.

House Bill 1230 requires experience-rated group disability income insurers in Washington state to include all applicable rating factors and credibility formulas when they file their rate manuals with the Insurance Commissioner. These filings must be detailed enough to allow the Commissioner to confirm if a group is credible and to replicate the premium rates for that group based on its experience and demographics. This bill aims to provide greater transparency and oversight for how these specific disability insurance rates are calculated.
