ISO's Actuarial and Strategic Data Insights

(Formerly Actuarial Service)


Information that enlightens

ISO’s Actuarial and Strategic Data Insights, formerly Actuarial Service, provides the information you need to enhance your decision making and boost your productivity and profitability. Using ISO’s data to supplement your own experience, you’ll be able to make better-informed decisions about product pricing, marketing, underwriting, reserve adequacy, and reinsurance needs.

Actuarial and Strategic Data Insights give you timely, accurate information on such topics as loss and premium trend, risk classifications, loss development, increased limits factors, catastrophe and excess losses, and expenses. You get aggregate data in various levels of detail, as well as the methods, formulas, and judgments of our professional staff of actuaries.

The data and insights to fuel informed decisions

ISO’s Actuarial and Strategic Data Insights, available by line of insurance, offers an array of reports with deep data and analyses on a wide range of topics.
Depending on business line, the available reports could include:

  • Trend: Estimate future costs using ISO’s analysis of how inflation and other factors affect cost levels and whether claim frequency is rising or falling.
  • Loss development: Evaluate reserve adequacy and conduct cash flow and investment income analyses.
  • Classification/territory: Determine which market segments are profitable or unprofitable to target or adjust your marketing efforts.
  • Increased limits: Measure costs associated with higher coverage limits to evaluate your reinsurance needs, or develop offerings, and negotiate prices.
  • Catastrophe: Assess the financial risk arising from catastrophic events.
  • Size of loss: Analyze loss size trends over time and the relationship of allocated loss adjustment expense (predominantly legal fees) to loss severity using ISO’s distribution of losses by size.
  • Cause of loss: Evaluate whether a particular peril is increasing or decreasing in importance as a cost driver and compare loss distribution by peril geographically using ISO’s analysis of loss trends by peril.
  • Expenses: Compare your underwriting expenses against aggregate results to gauge your productivity and efficiency.
  • Fast Track: Aggregate information on insurance from the Fast Track Monitoring System.

ISO data serves as a benchmark

ISO’s compilations and analyses provide a source of data aggregated over a broad base of insurers. You can evaluate your own company’s loss and expense experience against that aggregate. Using the results of your comparison, you can focus on problem areas in your book of business and weigh alternate underwriting strategies or claims practices. You can identify profitable new markets to enter or new classes of business to write by evaluating differences in experience across states, territories, and classes.

If you need data that our standard reports don’t display, we can prepare customized reports and data files according to criteria you define. Your Actuarial and Strategic Data Insights participation entitles you to a discount on any customized report you order.

In-depth analysis that’s easy to use and understand

Our actuaries compile and analyze complex data and present the data in formats that you can easily use and understand. We’ve designed the exhibits in our circulars and written the accompanying explanations to be clear and informative. In addition to providing vital information, our circulars make valuable training and educational tools for your actuarial staff. And if you have any questions about the analyses, ISO’s professional team of actuaries is always ready to help.

Download options

As an Actuarial and Strategic Data Insights participant, you can download ISO’s relevant circulars from ISOnet® (ISO’s Internet delivery service) as PDF files and as a combination of Microsoft® Word 2003 documents (circular text) and Excel 2003 spreadsheets (circular exhibits). The spreadsheet download facilitates faster, simpler, and less error-prone integration of ISO’s aggregate data and analyses into your decision-making process.

You can take advantage of the formulas built into our Excel files to present your own company data in reports similar to ISO’s and to help automate your analyses. You can then easily compare your results with ISO’s aggregate benchmark to identify problems to address or markets in which you can competitively target your business.

And you can readily extend or adapt the analyses by changing the assumptions on trend, loss development, and other parameters, or performing "what-if" analyses to gain additional insight into the ISO calculations.
