Chapter 6. Catastrophe and Risk


Managing Director, Risk Advisory, Unicredit Group Europe

Abstract: Low-frequency/high-severity catastrophe events impacting companies operating in vulnerable areas have the potential of creating very large economic losses and must be managed through a rigorous risk management process. Development of a proper risk framework requires an understanding of both frequency and severity of natural and man-made catastrophes. Companies can examine frequencies by determining recurrence intervals, occurrence frequencies, and nonencounter probabilities (which together help indicate whether a catastrophe is likely to be nonrepetitive, irregular, regular, or seasonal), and they can estimate economic severity by coupling the potential magnitude of a disaster with direct and indirect losses and secondary costs. These event loss results can then be used to create a suitable risk management plan.
