The Division has determined that certain rating practices lead to excessive, inadequate or unfairly discriminatory rates and are unfair methods of competition and/or unfair or deceptive acts or practices in the business of insurance. Therefore, in accordance with § 10-3-1110(1), C.R.S., it is considered an unfairly discriminatory practice for a company to include, in any component of a rate, any amount intended to recover losses or expenses incurred in another state or jurisdiction due to any referendum, law or regulation which requires a general reduction in rates. This subsection shall not prohibit the use of national, regional or other industry data as a necessary and actuarially supportable supplement to Colorado data that is not fully credible.
