The document summarizes the key points of a seminar about analyzing and preparing for extreme catastrophic events that can impact infrastructure projects. It discusses how more frequent low probability, high impact events can seriously affect project cash flows and debt obligations. It provides an example of flooding in Australia in 2010 that impacted 200,000 people and reduced GDP by $30 billion. It also outlines factors projects face, common risk mitigation strategies, and how an extreme event could impact a gold mining project through disruption to operations, reduced revenues and costs, insurance claims, and debt repayments not being met.
