Aon’s Approach


  • Use of a proprietary Risk Rating Matrix, allowing clients to benchmark their risk profile against relevant standards, and allowing insurers to partner in the goal of continuous improvement
  • Use of ExTool as a primary modeling methodology for the assessment of estimated maximum losses (EMLs). ExTool is the most widely accepted EML model in the global insurance market, and is used by Aon’s risk engineers as a guide in this critically important facet of risk management
  • An innovative range of e-tools and data management capabilities including Aon GPS, an internet-based risk survey reporting platform, and a proprietary loss database used to assist clients in the consideration of “what-if” scenarios
  • Provision of a risk improvement strategy, detailing and categorizing recommendations to allow the client to consider each item from an operational, strategic and financial perspective, and to plan appropriately for capital expenditure
