Wheaton, Ill., March 6, 2009—A national insurance advisory organization has initiated a countrywide filing of new and revised rules, factors and loss costs for insuring mobile homes.

The American Association of Insurance Services (AAIS) is filing several enhancements to the rating information in its Mobile-Homeowners Program. AAIS develops standardized policy forms and rating information used by more than 600 property/casualty insurers throughout the U.S.

The latest AAIS Mobile-Homeowners enhancements include:

• Credits for mobile homes built and first occupied within the last 10 years;

• An experience rating plan which provides credits and surcharges based on an insured's claims payment history and tenure with the insurance company;

• Modified tie-down credits dependent on the quality and type of tie-downs installed;

• A surcharge for a mobile home that is unoccupied for three or more months; and

• Credits for a composition shingle roof, enclosed masonry foundation, or full skirt covering.

In addition, the enhancements provide a revised premium calculation rule to support separate rating procedures for windstorm or hail (wind) and all other perils (non-wind), along with:

• Expanded wind and non-wind deductible options and factors;

• Revised policy form relativities that apply to the non-wind basic policy premium;

• Revised fire protection definitions and protection relativities that apply to the non-wind basic policy premium; and

• Revised wind and non-wind amount of insurance relativities.
