Abstract

This paper presents a formula for calculating a reinsurance premium which has been
determined by incorporating a lognormal-burr model into a risk-adjusted premium calculating
principle called the PH-transform principle. The lognormal-burr model has been selected and
validated as the best fitting model for the used insurance data among the eight candidates of
composite lognormal models. The formula has then been applied in calculating reinsurance
premiums for an automobile insurance branch under an excess of loss non-proportional
reinsurance treaty.
