The results shown in Table 2 and Fig. 4 do not clearly distinguish which reinsurance structure gives the best outcome
(i.e., minimizing the risk of the retained insurance losses and maximizing the retained premiums) for the life insurance business.
The semi-variance of the retained claims is the smallest under surplus reinsurance (0.007).
The insurer, however, retains the largest amount of premium when using the quota-share reinsurance (PRS = 7.24 and retained premiums after claims are just under A$102 mln. (US$88 mln.)).
Nevertheless, the risk of the retained losses under quota-share is significantly larger than under surplus or the combination of quota-share and surplus reinsurance (semi-variance = 0.027).
