Note: Paragraph (a) is intended to prohibit insurance underwriting shortcuts which unfairly label risks as poor risks because of their geographic location. A refusal, nonrenewal, cancellation or limitation of insurance coverage is prohibited if the reason for such refusal, nonrenewal, cancellation or limitation is the geographic location of the risk. An exception to this general rule is provided, however, in situations where the refusal, nonrenewal, cancellation or limitation is based upon a legitimate business need and the refusal, nonrenewal, cancellation or limitation is not a mere pretext for unfair discrimination. Examples of such situations include refusals to insure when the risk is located in areas prone to natural catastrophes, i.e., earthquakes, floods, hurricanes, and refusals to insure because the insurer already has a very high concentration of risks in a particular geographic area. It is intended that the person charged with a violation of this rule be given the burden of proof in establishing any "business purpose" exception. The burden of proving that a refusal, nonrenewal, cancellation or limitation of insurance coverage is not subterfuge for unfair discrimination should likewise fall upon the person charged with a violation of this rule.
