This panel will explore advanced topics in property per risk pricing and accumulation. Exposure rating and treatment of large losses will be a central point. Topics to be explored will focus on the practical application of tools in the actuary's and underwriter's arsenal, which are not widely known among the actuarial community. These tools include an approach to the allocation of grouped or blanket policy premium to the individual risk level, and the use of an international cost index to make U.S. exposure curves more appropriate for rating non-U.S. risks. A survey of accumulation methodologies utilized to accumulate cat exposure embedded within per risk treaties with cat exposure from cat treaties will be discussed. The use of the beta distribution in the context of cat exposure to per risk treaties will also be explored.
