摘要:
A computer-based system configured to calculate an estimated risk premium for reinsurance of a cedent's insurance policies covering loss event related fatalities and disabilities. The system stores, for different market scenarios, representative of loss events for a defined insurance market, frequency of loss event and number of insured individuals involved in the loss event. Based on these market scenarios and considering the cedent's market share, the system calculates individual scenarios, indicative of the cedent's exposure to the loss events. Using a standard distribution for the number of insured individuals involved in the loss event, for example a Pareto distribution, and using individual scenarios as interpolation points, the system calculates a set of loss event frequencies by number of individuals insured by the cedent and involved in a loss event. Finally, the system calculates the estimated risk premium from the set of loss event frequencies and from severity data.

(Meth)acrylate salt polymers are prepared by free-radical polymerization of (meth)acrylate salt with or without other monomers in an aqueous medium by using a supersaturated aqueous solution of (meth)acrylate salt. The resulting highly concentrated reaction mixtures are notable for their high solids content and increased space-time yield.
