Description: The National Association of Insurance Commissioners (NAIC) is in the middle of of a project to change the real-world economic scenario generator (RW ESG) prescribed for principle-based reserve and capital calculations. The presenters will provide a brief summary of the NAIC's RW ESG project and provide a general overview of RW ESGs. In addition to that, they will explain how RW ESGs impact principle-based reserve and capital levels and consider potential differences between the currently prescribed RW ESG and the proposed RW ESG.

Description: The method described in this paper is to allocate surplus to each category of business and reserves in proportion to its estimated effect on an insurer's surplus variation. Risk load for each category of business is then selected so that the return on allocated surplus for each category is equal to the overall return on surplus.
