How Are Insurers Using ISO’s New Algorithm Files?

An interesting case study from ISO is in the works. The headline is "Forty-Six States in Two Months: How One Insurer Implemented ISO's Commercial Auto Rating in Record Time."

We're still developing the final report, but already the findings are clear. The newly formatted ISO Rating Service® and ISO Electronic Rating Content algorithm files, which we announced in October 2011, and supporting tools can dramatically accelerate your analysis efforts. And you can upload the files directly to your system, saving specification and implementation time.

According to the case study, the insurer "met the tight deadline and succeeded in implementing ISO's commercial auto rating for 46 states by March 1 – much less than two months after the start of the project."

ISO content is powerful. Our prospective loss costs, policy language, and rating and policywriting rules are an industry standard for property/casualty insurers. Our new algorithms put the rules into structured, actionable formats in Microsoft Excel and XML. The algorithms provide the implementation-level details for:

  • premium calculation
  • forms attachment logic
  • statistical code assignment (using ISO's full stat plans)
  • business edits

And if your company uses ISO content to develop its own insurance offerings, you'll want to check out our additional methods for delivering that content in electronic formats.
