Insurance

Insurance, in law and economics, is a form of risk management primarily used to hedge against the risk of a contingent loss.

Insurance is defined as the equitable transfer of the risk of a loss, from one entity to another, in exchange for a premium, and can be thought of as a guaranteed small loss to prevent a large, possibly devastating loss.

An insurer is a company selling the insurance; an insured is the person or entity buying the insurance. The insurance rate is a factor used to determine the amount, called the premium, to be charged for a certain amount of insurance coverage.

Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study and practice.

Types of insurance

Any risk that can be quantified can potentially be insured. Specific kinds of risk that may give rise to claims are known as "perils". An insurance policy will set out in detail which perils are covered by the policy and which are not. Below are (non-exhaustive) lists of the many different types of insurance that exist. A single policy may cover risks in one or more of the categories set out below. For example, auto insurance would typically cover both property risk (covering the risk of theft or damage to the car) and liability risk (covering legal claims from causing an accident). A homeowner's insurance policy in the U.S. typically includes property insurance covering damage to the home and the owner's belongings, liability insurance covering certain legal claims against the owner, and even a small amount of coverage for medical expenses of guests who are injured on the owner's property.

Business insurance can be any kind of insurance that protects businesses against risks. Some principal subtypes of business insurance are (a) the various kinds of professional liability insurance, also called professional indemnity insurance, which are discussed below under that name; and (b) the business owner's policy (BOP), which bundles into one policy many of the kinds of coverage that a business owner needs, in a way analogous to how homeowners insurance bundles the coverages that a homeowner needs.

Auto insurance

Auto insurance protects you against financial loss if you have an accident. It is a contract between you and the insurance company. You agree to pay the premium and the insurance company agrees to pay your losses as defined in your policy. Auto insurance provides property, liability and medical coverage: (1) Property coverage pays for damage to or theft of your car. (2) Liability coverage pays for your legal responsibility to others for bodily injury or property damage. and (3) Medical coverage pays for the cost of treating injuries, rehabilitation and sometimes lost wages and funeral expenses. An auto insurance policy is comprised of six different kinds of coverage. Most countries require you to buy some, but not all, of these coverages. If you're financing a car, your lender may also have requirements.

Most auto policies are for six months to a year. Your insurance company should notify you by mail when it’s time to renew the policy and to pay your premium.

Home insurance

Home insurance provides compensation for damage or destruction of a home from disasters. In some geographical areas, the standard insurances excludes certain types of disasters, such as flood and earthquakes, that require additional coverage. Maintenance-related problems are the homeowners' responsibility. The policy may include inventory, or this can be bought as a separate policy, especially for people who rent housing. In some countries, insurers offer a package which may include liability and legal responsibility for injuries and property damage caused by members of the household, including pets.

Health

Health insurance policies by the National Health Service in the United Kingdom (NHS) or other publicly-funded health programs will cover the cost of medical treatments. Dental insurance, like medical insurance, is coverage for individuals to protect them against dental costs. In the U.S., dental insurance is often part of an employer's benefits package, along with health insurance. Most countries rely on public funding to ensure that all citizens have universal access to health care.
