WAC 284-24A-045. If an insurer uses credit history or insurance scores to segment personal insurance business for rating purposes, how can the insurer show that its rating plan results in premium rates that are not excessive, inadequate, or unfairly discriminatory?

If an insurer uses credit history or insurance scores to segment personal insurance business for rating purposes, the insurer must: (1) Submit a multi variate analysis with the first rate and rule filing the insurer makes to comply with this law. (2) Submit a multivariate analysis any time the insurer uses credit history or an insurance score to revise a risk classification plan, rating factor, rating plan, rating tier, or base rates.
