"In Sava Re Group we have been working with Risk Explorer for over 5 years now. Its intuitive and user-friendly interface requires no programming skills and allows new users to quickly master the basic functionalities. A wide selection of loss modelling options and asset classes covers the majority of asset, insurance and reinsurance liability portfolio. If standard objects nevertheless fall short of any important specifics, user-defined wizard presents an easy-to-use and well integrated solution for the problem. When a newly desired functionality could be beneficial for other users as well, we contact URS team to implement it as a standard object in future releases. Due to their fast responsiveness and great cooperation many new features were implemented during the last 5 years, including those that were added specifically on our request. Another thing we appreciate is a great connectivity with Excel. Where the model requires larger quantity of data, they can be simply edited in Excel and imported in a spreadsheet format. Using the Excel add-ins one can create tidy reports that refresh automatically after each simulation run. In addition to reporting functions Excel add-ins offer also a large variety of statistical functions that can be used either in connection with Risk Explorer models or for entirely unrelated calculations. To sum up, we have been very satisfied with our cooperation with URS so far and Risk Explorer turned out to be a great tool to support our modelling ambitions."
