Insurance 101

Here are a few key definitions and concepts which might help those new to the insurance forum more rapidly understand the nature of the insurance problems our society faces. I will add more as time allows and hopefully we might combine them with other concepts.

What is Insurance?

One definition of insurance is a system to make large financial losses more affordable by pooling the risks of many individuals and business entities and transferring them to an insurance provider for a premium. More basically insurance is the process of the assumption of risk from one party to another for a fee.

The key to understanding insurance is the concept of risk assumption. In insurance terms risk is the chance of loss of that which is insured.

For the purposes of this web site the main type of insurance studied is property/casualty in general and catastrophe insurance (CAT) in particular. ISO defines a catastrophe as an event that causes $25 million or more in insured property losses and affects a significant number of property/casualty policyholders and insurers.

What is the role of insurance providers?

Insurance providers core function in society is that of helping to manage risk. Insurance plays a vital role in helping individuals and businesses prepare for and recover from the potentially devastating effects of a disaster such as a catastrophic hurricane or earthquake.

Insurance providers help society pre-pay for their risk needs. Catastrophic insurance providers have a special role in helping entire communities pre-pay for their disaster needs. Because their losses are more volatile the property/casualty insurers invest largely in high-quality liquid securities, which can be sold quickly to pay claims resulting from a major hurricane, earthquake or man-made disaster such as a terrorist attack.

Who are the leading providers?

Data from the National Association of Insurance Commissioners (NAIC) identifies the 10 leading writers of non-governmental property/casualty insurance by direct premiums written during the 2006 calendar year.

NAIC percentages were based on the U.S. total including territories before reinsurance transactions, excluding state funds.

It should be noted the federal government is considered by many CEO’s of insurance and individuals as the insurer of last resort. The federal government is also the sole insurance provider for basic flood coverage in the United States.
