Insurance companies play an important role in an economy in that they are risk bearers or the underwriters of risk for a wide range of insurable events.

The payment that they receive is called a premium. Between the time that the premium is made by the policy holder to the insurance company and a claim on the insurance company is paid out, the insurance company can invest those proceeds in the financial market.

Life policies can be for pure life insurance coverage (e.g., term life insurance) or can have an investment component (e.g., cash value life insurance).
• Health insurance. The risk insured is the cost of medical treatment for the insured.
• Property and casualty insurance. The risk insured against financial loss resulting from the damage, destruction, or loss to property of the insured property attributable to an identifiable event that is sudden, unexpected, or unusual.
