Lines of insurance

One of the very basic principles of insurance is that insurance is comprised of different types of coverages for different types of risks or exposures. In this lesson, we will look at the four basic lines of insurance:
  • Life insurance
  • Health / disability
  • Property
  • Liability / casualty

    Life insurance
    According to the National Association of Insurance Commissioners (NAIC) there were 1,796 insurance companies in l997 that sold life and health insurance. That compares to 3,366 that wrote property and casualty insurance during the same timeframe.

    In simple terms, life insurance is designed to pay benefits to designated survivors in the event of an insured's death.

    People buy life insurance in order to:
  • Provide income to the surviving spouse and children
  • Make sure the house is paid for in the event of death
  • Pay other final expenses upon death
  • Leave money for children's education
  • Arrange estate planning

    Health and disability insurance
    Health and disability insurance reimburses the insured for such issues as:
  • Medical bills incurred due to accident or illness
  • Loss of income resulting from an injury or illness
  • Reimbursement for extra expenses

    In l997 total national health care expenditures amounted to $1.1 trillion or almost $4,000 per capita. The government's large-scale participation in providing health care through Medicaid and Medicare makes comparisons difficult between the health care sector and the life and property / casualty sectors, which are mostly private.

    Property insurance
    Property insurance is designed to protect the owner or holder of property from incurring a financial loss.

    There are many classes of property that might be insured such as:
  • Homes
  • Commercial buildings
  • Personal or business property
  • Autos or other vehicles
  • Other property items

    Property forms also deal with additional expenses or income losses that an insured would suffer because their property is damaged.

    Liability / casualty insurance
    Liability or casualty insurance is a more difficult line of insurance to define. One of the simplest concepts concerning liability is the risk (possibility) that an insured will suffer financial loss as a result of their actions toward another (third party).

    If an insured hurts somebody or damages someone's property negligently or wrongfully then the insured will have to pay for those damages. This is referred to as "legal liability" and the amount the insured has to pay the third party is called "damages". An example would be if you rear-ended another vehicle and injured the driver of the other car.

    The person that makes the claim is called the "third party" and for that reason, liability insurance is sometimes referred to as "third party" insurance. The insured is the first party, the insurance company is the second party and the claimant against the insured is the third party.

    Property insurance and liability / casualty insurance are often seen as going hand-in-hand. For example, when you take out insurance on your car, you would looking into getting both collision insurance to cover damage to your car and liability insurance to protect against any expense that you would incur if you injured someone else and their car.
