Quota-share and surplus reinsurance leads to the lowest retained risk, with a semi-variance of the retained claims equal to 0.011.
Relatively low insurer retention levels (the insurer retains on average 55% of the total risk), large variations in insurer retentions (seeTable 1), and high reinsurance premiums (see Appendix B), make surplus reinsurance sub-optimal under both risk and profitability criteria for the Income Protection insurance (seeFig. 2).
