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).
