Stores values used to disaggregate exposures in China from the province (area) or city level to the county (subarea) level. The values are based on weighted averages developed using AIR's Industry Exposure Database.
For example, Touchstone Re may multiply the total exposure for each province, peril, and line of business by the ratios supplied in the table to determine the portion of the exposure to associate with each county. How Touchstone Re computes exposure depends on whether a user excluded any provinces or cities from the computation.
