What is 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. Insurer is the company that sells the insurance. 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.

How to File an Insurance Claim?

Principles of insurance

Commercially insurable risks typically share seven common characteristics.^[1]

1. A large number of homogeneous exposure units. The vast majority of insurance policies are provided for individual members of very large classes. Automobile insurance, for example, covered about 175 million automobiles in the United States in 2004.^[2] The existence of a large number of homogeneous exposure units allows insurers to benefit from the so-called “law of large numbers,” which in effect states that as the number of exposure units increases, the actual results are increasingly likely to become close to expected results. There are exceptions to this criterion. Lloyd's of London is famous for insuring the life or health of actors, actresses and sports figures. Satellite Launch insurance covers events that are infrequent. Large commercial property policies may insure exceptional properties for which there are no ‘homogeneous’ exposure units. Despite failing on this criterion, many exposures like these are generally considered to be insurable.
2. Definite Loss. The event that gives rise to the loss that is subject to insurance should, at least in principle, take place at a known time, in a known place, and from a known cause. The classic example is death of an insured on a life insurance policy. Fire, automobile accidents, and worker injuries may all easily meet this criterion. Other types of losses may only be definite in theory. Occupational disease, for instance, may involve prolonged exposure to injurious conditions where no specific time, place or cause is identifiable. Ideally, the time, place and cause of a loss should be clear enough that a reasonable person, with sufficient information, could objectively verify all three elements.
3. Accidental Loss. The event that constitutes the trigger of a claim should be fortuitous, or at least outside the control of the beneficiary of the insurance. The loss should be ‘pure,’ in the sense that it results from an event for which there is only the opportunity for cost. Events that contain speculative elements, such as ordinary business risks, are generally not considered insurable.
4. Large Loss. The size of the loss must be meaningful from the perspective of the insured. Insurance premiums need to cover both the expected cost of losses, plus the cost of issuing and administering the policy, adjusting losses, and supplying the capital needed to reasonably assure that the insurer will be able to pay claims. For small losses these latter costs may be several times the size of the expected cost of losses. There is little point in paying such costs unless the protection offered has real value to a buyer.
5. Affordable Premium. If the likelihood of an insured event is so high, or the cost of the event so large, that the resulting premium is large relative to the amount of protection offered, it is not likely that anyone will buy insurance, even if on offer. Further, as the accounting profession formally recognizes in financial accounting standards, the premium cannot be so large that there is not a reasonable chance of a significant loss to the insurer. If there is no such chance of loss, the transaction may have the form of insurance, but not the substance. (See the U.S. Financial Accounting Standards Board standard number 113)
6. Calculable Loss. There are two elements that must be at least estimable, if not formally calculable: the probability of loss, and the attendant cost. Probability of loss is generally an empirical exercise, while cost has more to do with the ability of a reasonable person in possession of a copy of the insurance policy and a proof of loss associated with a claim presented under that policy to make a reasonably definite and objective evaluation of the amount of the loss recoverable as a result of the claim.
7. Limited risk of catastrophically large losses. The essential risk is often aggregation. If the same event can cause losses to numerous policyholders of the same insurer, the ability of that insurer to issue policies becomes constrained, not by factors surrounding the individual characteristics of a given policyholder, but by the factors surrounding the sum of all policyholders so exposed. Typically, insurers prefer to limit their exposure to a loss from a single event to some small portion of their capital base, on the order of 5 percent. Where the loss can be aggregated, or an individual policy could produce exceptionally large claims, the capital constraint will restrict an insurers appetite for additional policyholders. The classic example is earthquake insurance, where the ability of an underwriter to issue a new policy depends on the number and size of the policies that it has already underwritten. Wind insurance in hurricane zones, particularly along coast lines, is another example of this phenomenon. In extreme cases, the aggregation can affect the entire industry, since the combined capital of insurers and reinsurers can be small compared to the needs of potential policyholders in areas exposed to aggregation risk. In commercial fire insurance it is possible to find single properties whose total exposed value is well in excess of any individual insurer’s capital constraint. Such properties are generally shared among several insurers, or are insured by a single insurer who syndicates the risk into the reinsurance market.

History of insurance

In some sense we can say that insurance appears simultaneously with the appearance of human society. We know of two types of economies in human societies: money economies (with markets, money, financial instruments and so on) and non-money or natural economies (without money, markets, financial instruments and so on). The second type is a more ancient form than the first. In such an economy and community, we can see insurance in the form of people helping each other. For example, if a house burns down, the members of the community help build a new one. Should the same thing happen to one's neighbour, the other neighbours must help. Otherwise, neighbours will not receive help in the future. This type of insurance has survived to the present day in some countries where modern money economy with its financial instruments is not widespread (for example countries in the territory of the former Soviet Union).

Turning to insurance in the modern sense (i.e., insurance in a modern money economy, in which insurance is part of the financial sphere), early methods of transferring or distributing risk were practiced by Chinese and Babylonian traders as long ago as the 3rd and 2nd millennia BC, respectively. Chinese merchants travelling treacherous river rapids would redistribute their wares across many vessels to limit the loss due to any single vessel's capsizing. The Babylonians developed a system which was recorded in the famous Code of Hammurabi, c. 1750 BC, and practiced by early Mediterranean sailing merchants. If a merchant received a loan to fund his shipment, he would pay the lender an additional sum in exchange for the lender's guarantee to cancel the loan should the shipment be stolen.

Achaemenian monarchs were the first to insure their people and made it official by registering the insuring process in governmental notary offices. The insurance tradition was performed each year in Norouz (beginning of the Iranian New Year); the heads of different ethnic groups as well as others willing to take part, presented gifts to the monarch. The most important gift was presented during a special ceremony. When a gift was worth more than 10,000 Derrik (Achaemenian gold coin) the issue was registered in a special office. This was advantageous to those who presented such special gifts. For others, the presents were fairly assessed by the confidants of the court. Then the assessment was registered in special offices.

The purpose of registering was that whenever the person who presented the gift registered by the court was in trouble, the monarch and the court would help him. Jahez, a historian and writer, writes in one of his books on ancient Iran: "[W]henever the owner of the present is in trouble or wants to construct a building, set up a feast, have his children married, etc. the one in charge of this in the court would check the registration. If the registered amount exceeded 10,000 Derrik, he or she would receive an amount of twice as much."[1]

A thousand years later, the inhabitants of Rhodes invented the concept of the 'general average'. Merchants whose goods were being shipped together would pay a proportionally divided premium which would be used to reimburse any merchant whose goods were jettisoned during storm or sinkage.

The Greeks and Romans introduced the origins of health and life insurance c. 600 AD when they organized guilds called "benevolent societies" which cared for the families and paid funeral expenses of members upon death. Guilds in the Middle Ages served a similar purpose. The Talmud deals with several aspects of insuring goods. Before insurance was established in the late 17th century, "friendly societies" existed in England, in which people donated amounts of money to a general sum that could be used for emergencies.

Separate insurance contracts (i.e., insurance policies not bundled with loans or other kinds of contracts) were invented in Genoa in the 14th century, as were insurance pools backed by pledges of landed estates. These new insurance contracts allowed insurance to be separated from investment, a separation of roles that first proved useful in marine insurance. Insurance became far more sophisticated in post-Renaissance Europe, and specialized varieties developed.

Toward the end of the seventeenth century, London's growing importance as a centre for trade increased demand for marine insurance. In the late 1680s, Mr. Edward Lloyd opened a coffee house that became a popular haunt of ship owners, merchants, and ships’ captains, and thereby a reliable source of the latest shipping news. It became the meeting place for parties wishing to insure cargoes and ships, and those willing to underwrite such ventures. Today, Lloyd's of London remains the leading market (note that it is not an insurance company) for marine and other specialist types of insurance, but it works rather differently than the more familiar kinds of insurance.

Insurance as we know it today can be traced to the Great Fire of London, which in 1666 devoured 13,200 houses. In the aftermath of this disaster, Nicholas Barbon opened an office to insure buildings. In 1680, he established England's first fire insurance company, "The Fire Office," to insure brick and frame homes.

The first insurance company in the United States underwrote fire insurance and was formed in Charles Town (modern-day Charleston), South Carolina, in 1732.

Benjamin Franklin helped to popularize and make standard the practice of insurance, particularly against fire in the form of perpetual insurance. In 1752, he founded the Philadelphia Contributionship for the Insurance of Houses from Loss by Fire. Franklin's company was the first to make contributions toward fire prevention. Not only did his company warn against certain fire hazards, it refused to insure certain buildings where the risk of fire was too great, such as all wooden houses.

In the United States, regulation of the insurance industry is highly Balkanized, with primary responsibility assumed by individual state insurance departments. Whereas insurance markets have become centralized nationally and internationally, state insurance commissioners operate individually, though at times in concert through a national insurance commissioners' organization. In recent years, some have called for a dual state and federal regulatory system for insurance similar to that which oversees state banks and national banks.

In the state of New York, which has unique laws in keeping with its stature as a global business centre, former New York Attorney General Eliot Spitzer was in a unique position to grapple with major national insurance brokerages. Spitzer alleged that Marsh & McLennan steered business to insurance carriers based on the amount of contingent commissions that could be extracted from carriers, rather than basing decisions on whether carriers had the best deals for clients. Several of the largest commercial insurance brokerages have since stopped accepting contingent commissions and have adopted new business models.

Types of insurance

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 forth 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 health insurance 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 owners 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.^[7]

Life & Annuity Coverages

• Life insurance provides a monetary benefit to a decedent's family or other designated beneficiary, and may specifically provide for income to an insured person's family, burial, funeral and other final expenses. Life insurance policies often allow the option of having the proceeds paid to the beneficiary either in a lump sum cash payment or an annuity.
• Annuities provide a stream of payments and are generally classified as insurance because they are issued by insurance companies and regulated as insurance and require the same kinds of actuarial and investment management expertise that life insurance requires. Annuities and pensions that pay a benefit for life are sometimes regarded as insurance against the possibility that a retiree will outlive his or her financial resources. In that sense, they are the complement of life insurance and, from an underwriting perspective, are the mirror image of life insurance.

Health Coverages

• Health insurance policies will often cover the cost of private medical treatments if the National Health Service in the UK (NHS) or other publicly-funded health programs do not pay for them. It will often result in quicker health care where better facilities are available.
• 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.

Disability Coverages

• Disability insurance policies provide financial support in the event the policyholder is unable to work because of disabling illness or injury. It provides monthly support to help pay such obligations as mortgages and credit cards.
• Total permanent disability insurance insurance provides benefits when a person is permanently disabled and can no longer work in their profession, often taken as an adjunct to life insurance.
• Disability overhead insurance allows business owners to cover the overhead expenses of their business while they are unable to work.
• Workers' compensation insurance replaces all or part of a worker's wages lost and accompanying medical expense incurred because of a job-related injury.

Property & Casualty Coverages

Property insurance provides protection against risks to property, such as fire, theft or weather damage. This includes specialized forms of insurance such as fire insurance, flood insurance, earthquake insurance, home insurance, inland marine insurance or boiler insurance.

Casualty insurance insures against accidents, not necessarily tied to any specific property.

• Automobile insurance, known in the UK as motor insurance, is probably the most common form of insurance and may cover both legal liability claims against the driver and loss of or damage to the insured's vehicle itself. Throughout the United States auto insurance policy is required to legally operate a motor vehicle on public roads. In some jurisdictions, bodily injury compensation for automobile accident victims has been changed to a no-fault system, which reduces or eliminates the ability to sue for compensation but provides automatic eligibility for benefits. Credit card companies insure against damage on rented cars.
  • Driving School Insurance insurance provides cover for any authorized driver whilst under going tuition, cover also unlike other motor policies provides cover for instructor liability where both the pupil and driving instructor are both equally liable in the event of a claim.
• Aviation insurance insures against hull, spares, deductible, hull wear and liability risks.
• Boiler insurance (also known as boiler and machinery insurance or equipment breakdown insurance) insures against accidental physical damage to equipment or machinery.
• Builder's risk insurance insures against the risk of physical loss or damage to property during construction. Builder's risk insurance is typically written on an "all risk" basis covering damage due to any cause (including the negligence of the insured) not otherwise expressly excluded.
• Crime insurance is a form of casualty insurance that covers the policyholder against losses arising from the criminal acts of third parties. For example, a company can obtain crime insurance to cover losses arising from theft or embezzlement.
• Crop insurance "Farmers use crop insurance to reduce or manage various risks associated with growing crops. Such risks include crop loss or damage caused by weather, hail, drought, frost damage, insects, or disease, for instance."^[8]
• Earthquake insurance is a form of property insurance that pays the policyholder in the event of an earthquake that causes damage to the property. Most ordinary homeowners insurance policies do not cover earthquake damage. Most earthquake insurance policies feature a high deductible. Rates depend on location and the probability of an earthquake, as well as the construction of the home.
• A fidelity bond is a form of casualty insurance that covers policyholders for losses that they incur as a result of fraudulent acts by specified individuals. It usually insures a business for losses caused by the dishonest acts of its employees.
• Fire insurance: See "Property insurance".
• Flood insurance protects against property loss due to flooding. Many insurers in the US do not provide flood insurance in some portions of the country. In response to this, the federal government created the National Flood Insurance Program which serves as the insurer of last resort.
• Hazard insurance: See "Property insurance".
• Home insurance or homeowners insurance: See "Property insurance".
• Marine insurance and marine cargo insurance cover the loss or damage of ships at sea or on inland waterways, and of the cargo that may be on them. When the owner of the cargo and the carrier are separate corporations, marine cargo insurance typically compensates the owner of cargo for losses sustained from fire, shipwreck, etc., but excludes losses that can be recovered from the carrier or the carrier's insurance. Many marine insurance underwriters will include "time element" coverage in such policies, which extends the indemnity to cover loss of profit and other business expenses attributable to the delay caused by a covered loss.
• Political risk insurance is a form of casualty insurance that can be taken out by businesses with operations in countries in which there is a risk that revolution or other political conditions will result in a loss.
• Surety bond insurance is a three party insurance guaranteeing the performance of the principal.
• Terrorism insurance provides protection against any loss or damage caused by terrorist activities.
• Volcano insurance is an insurance that covers volcano damage in Hawaii.
• Windstorm insurance is an insurance covering the damage that can be caused by hurricanes and tropical cyclones.

Liability Coverages

Liability insurance is a very broad superset that covers legal claims against the insured. Many types of insurance include an aspect of liability coverage. For example, a homeowner's insurance policy will normally include liability coverage which protects the insured in the event of a claim brought by someone who slips and falls on the property; automobile insurance also includes an aspect of liability insurance that indemnifies against the harm that a crashing car can cause to others' lives, health, or property. The protection offered by a liability insurance policy is twofold: a legal defense in the event of a lawsuit commenced against the policyholder and indemnification (payment on behalf of the insured) with respect to a settlement or court verdict. Liability policies typically cover only the negligence of the insured, and will not apply to results of willful or intentional acts by the insured.

• Environmental liability insurance protects the insured from bodily injury, property damage and cleanup costs as a result of the dispersal, release or escape of pollutants.
• Errors and omissions insurance: See "Professional liability insurance" under "Liability insurance".
• Professional liability insurance, also called professional indemnity insurance, protects professional practitioners such as architects, lawyers, doctors, and accountants against potential negligence claims made by their patients/clients. Professional liability insurance may take on different names depending on the profession. For example, professional liability insurance in reference to the medical profession may be called malpractice insurance. Notaries public may take out errors and omissions insurance (E&O). Other potential E&O policyholders include, for example, real estate brokers, home inspectors, appraisers, and website developers.
• Directors and officers liability insurance protects an organization (usually a corporation) from costs associated with litigation resulting from mistakes incurred by directors and officers for which they are liable. In the industry, it is usually called "D&O" for short.
• Prize indemnity insurance protects the insured from giving away a large prize at a specific event. Examples would include offering prizes to contestants who can make a half-court shot at a basketball game, or a hole-in-one at a golf tournament.

Credit Coverages

• Credit insurance repays some or all of a loan back when certain things happen to the borrower such as unemployment, disability, or death. Mortgage insurance is a form of credit insurance, although the name credit insurance more often is used to refer to policies that cover other kinds of debt.
• Mortgage insurance insures the lender against default by the borrower.
