Insurance

Insurance, in law and economics, is a form of risk management primarily used to hedge against the risk of potential financial loss. Ideally, insurance is defined as the equitable transfer of the risk of a potential loss, from one entity to another, in exchange for a reasonable fee. In practice, however, the business of providing insurance protection often ends up in litigation between the parties involved, while the responsibilities of regulating insurance markets routinely winds up as a political football for government agencies. In general, it is contract in which one party agrees to pay for another party's financial loss resulting from a specified event.

Determination of rate structures

The insurer uses actuarial science to quantify the risk they are willing to assume. Data is generated to approximate future claims, ordinarily with reasonable accuracy. Actuarial science uses statistics and probability to analyze the risks associated with the range of perils covered, and these scientific principles are used by insurers, in conjuction with additional factors, to determine rate structures.

For example, many individuals purchase homeowner's insurance policies by signing a contract paying a premium to an insurance company. If a covered loss occurs, the insurer is obliged by the terms of the contract to honor the insured's claim. For some policyholders, the amount of insurance benefits received from their insurer will greatly exceed the expense of premiums paid. Others may never make a claim or receive any benefit other than the peace of mind rendered by the security of an insurance policy. When averaged, the total claims expense paid by an insurer should be less than the total premiums paid by their policyholders, with the difference allocated to overhead and profit.

Insurance companies also earn investment profits. These are generated by investing premiums received until they are needed to pay claims. This money is called the 'float'. The insurer may make profits or losses from the value change in the float as well as interest or dividend on the float. In the United States, the underwriting loss of property and casualty insurance companies was $142.3 billion in the five years ending 2003. But overall profit for the same period was $68.4 billion, at the result of float. Some insurance industry insiders, most notably Hank Greenberg, do not believe that it is forever possible to sustain a profit from float without an underwriting profit as well.
