For insurers to be able to settle claims that may occur from existing portfolios of policies at some future time periods, it is imperative that they adequately model historical and current data on claims experience this can be used to project the expected future claims experience and setting sufficient reserves. By design, a single policy may possibly incur more than one claim such that the total number of claims as well as the total size of claims due on any given portfolio is unpredictable. Claims experience in non-life insurance is contingent on random eventualities of claim frequency and claim severity.
