This report identifies and estimates the contingent liabilities from natural disasters in Sri Lanka and presents options to manage them. Expenditures made in response to disasters are referred to as disaster-related contingent liabilities (OECD 2012). These expenses arise only if a contingent event, such as a disaster, happens. Two techniques are used in this report to estimate the value of contingent liabilities from natural disasters: direct estimation using historical expenditure data, and probabilistic modeling.
