Table 3 gives the summary of our risk–return estimation results.
More specifically,Table 3 reports the type of reinsurance coverage that gives the best outcome (e.g., the lowest semi-variance of retained claims, the highest RPS ratio) for each life insurance risk.
Our results indicate that surplus reinsurance is the most effective reinsurance coverage in reducing the risk of the retained losses.
That is, surplus reinsurance leads to the smallest semi-variance of the retained claims in four
out offive life insurance risks (i.e., TPD, Life Insurance, Funeral, and Trauma).
On the other hand, due to its lowest reinsurance premiums,quota-share reinsurance enables the insurer to retain the largest amount of premium for every A$1 of losses for all insurance risks, except TPD.
Furthermore, quota-share reinsurance leads to the highest under-writing profits before administrative expenses for Income Protection, Life Insurance, and Trauma insurance are deducted.
