Catastrophe exposure is managed within agreed appetites and tolerances. Baseline for both natural and non-natural perils: risk appetite statements exist, exposures are monitored against them and reported to senior management and the board, and business plans reflect the appetites (for non-natural, and vice versa). Higher levels derive appetites from the view of risk, cascade them to business functions and underwriting units with tolerances, limits and breach management, and make them forward-looking and responsive to events.
