Capital Modeling Tools

Learn how your organization can benefit from capital modeling tools. 

Why is Capital Modeling Important?

Forward-looking insurance companies are embracing capital modeling to manage their financial resources more effectively. By understanding the risks and uncertainties, insurance companies can make informed decisions about how to allocate their capital to maximize returns and minimize risk.

By modeling and stress-testing the complete risk profile of the business, insurance companies can determine how much capital they need to hold to meet regulatory requirements and sustain growth in a challenging and dynamic environment.

How We Collaborate with Clients

  • 01


    Work starts with a detailed discovery of a client’s needs to identify the solution that best fits their requirements. 

  • 02


    An implementation project helps integrate the capital model with the client data and system and to develop any bespoke functionality, with Aon and the client working as a team. 

  • 03


    The end solution can be delivered on-premise or as part of a hosted cloud offering. 

  • 04


    Clients are then fully self-sufficient and can operate and update the model themselves. However, we retain a close relationship to review how well the model works and offer 24/7 support.
