(2) The panel shall submit to the board, and the board shall approve, rates for earthquake loss assessment coverage that reasonably balance the earthquake loss assessment coverages offered and the potential exposure to earthquake loss resulting from an earthquake loss assessment policy as compared to the coverages offered and the potential exposure to earthquake loss resulting from residential property other than individual condominium policies. It is the intent of the Legislature, to the extent practicable, that rates charged by the authority to condominium loss assessment policyholders and residential property owner policyholders are treated equitably, and that a proportionate share of premiums is paid for potential exposure to loss, to the authority.
