ISO Portal Opens Up New Level of Detail to E&S, Reinsurance Markets

It’s not surprising that excess and surplus (E&S) underwriters have traditionally been forced to rely on experience and judgment to price insurance policies. After all, the non-admitted market is about as varied as you will find anywhere in the insurance world. But fortunately, there are tools today that can handle the challenge and help underwriters make difficult pricing decisions.

One of those tools is the ISO portal, which opens up a new level of granularity to E&S and reinsurance pricing. I recently recorded a short demo of the portal that shows how you can use it to analyze loss costs by individual risk and ZIP code across 17 different lines of insurance. As you’ll see in the demo, the portal is easy to use and allows you to zoom in on the data to make better pricing decisions. Underlying loss costs are downloadable into a Microsoft® Access database, making it easy to incorporate ISO advisory loss costs into your existing rating procedures.

To view the recording online, please visit the ISO portal website. If you have any questions about the portal or would like to learn more, please feel free to contact me at
