Since 1971, ISO has been the leading supplier of information about property and liability risk. Our statistical, actuarial, and underwriting information is a vital resource to insurance companies, government regulators, and other insurance organizations. And ISO's standardized policy language is the foundation on which many insurers build their coverage programs.

Today, ISO is using the latest technology to collect, analyze, develop, and deliver information for customers in a wide variety of industries. We're a business-to-business e-commerce company with a heritage that goes back more than 30 years.

Size and scope

ISO and its subsidiaries have more than 3,200 employees working in locations throughout the United States and around the world. About 1,140 work in our home office in Jersey City, New Jersey.

The ISO family of companies serves customers in the insurance, mortgage lending, and healthcare industries, in government, and in the human resources and risk-management functions of all industries.

How does ISO operate?

Unlike most businesses, insurance companies can't set their prices based on known costs for production and distribution. Instead, insurers need to project future claim costs by examining data from the past. That's where ISO comes in.

ISO's data and statistical services

ISO maintains one of the largest private databases in the world. Each year, insurers send us more than 2 billion detailed records of insurance premiums collected and losses paid. Our professional staff members analyze insurer data and turn it into meaningful information.

ISO's actuarial services

After ISO pools data from many insurers, our actuaries perform sophisticated analyses to help customers make decisions about their pricing, loss reserving, and marketing.

ISO's standard and customized policy language services

ISO is the acknowledged leader in writing policy language to cover all kinds of property and liability risks. All ISO policy forms — personal and commercial — use easy-to-read language that helps consumers know what they're buying and salespeople know what they're selling. ISO monitors legislative, regulatory, and legal developments; and we modify our forms to reflect law changes, new regulations, and court rulings.

ISO's consulting services

ISO's active consulting practice offers a variety of services to help customers move into new markets, reassess the ones they're already in, and gain competitive advantages.

ISO's risk-decision products and services

ISO supplies a wide array of information that underwriters use to evaluate and price particular risks. We maintain a 600-person field staff trained to gather information on-site about individual properties and communities. Insurers use that information in underwriting personal and commercial property insurance, as well as commercial liability and workers compensation policies.

ISO also uses sophisticated geographic information systems, satellite imagery, and other cutting-edge technologies to help customers define and manage their risk.

ISO claims information

Each year, insurance companies and others send ISO tens of millions of reports on individual insurance claims. We store those reports in comprehensive databases that help insurers and other customers detect and prevent claim fraud, evaluate risk, and process meritorious claims. And we supply software to let users conduct broad and flexible searches of the data.

Predictive modeling and scoring

Capitalizing on our expertise in delivering data, analytics, and decision-support products, ISO is developing practical tools for predictive modeling and scoring of risk. Predictive modeling is the process of choosing data and mathematical formulas to predict a “quantity of interest.” For an insurance company, a quantity of interest could be the expected losses for a single insurance policy, the probability that a particular claim is fraudulent, or any other quantity that will help an insurer make business decisions. For ease of use, ISO often arranges our models to create numeric scores that customers can use in decision making. ISO is a leader in research and development of modeling and scoring systems.
