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, in economics, 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.
Principles of Insurance
Commercially insurable risks typically share seven common characteristics.
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.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.
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.
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.
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.
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 (See FAS 113 for example), 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.
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.
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.
An entity seeking to transfer risk (an individual, corporation, or association of any type, etc.) becomes the 'insured' party once risk is assumed by an 'insurer', the insuring party, by means of a contract, called an insurance 'policy'. Generally, an insurance contract includes, at a minimum, the following elements: the parties (the insurer, the insured, the beneficiaries), the premium, the period of coverage, the particular loss event covered, the amount of coverage (i.e., the amount to be paid to the insured or beneficiary in the event of a loss), and exclusions (events not covered). An insured is thus said to be "indemnified" against the loss events covered in the policy.
When insured parties experience a loss for a specified peril, the coverage entitles the policyholder to make a 'claim' against the insurer for the covered amount of loss as specified by the policy. The fee paid by the insured to the insurer for assuming the risk is called the 'premium'. Insurance premiums from many insureds are used to fund accounts reserved for later payment of claims—in theory for a relatively few claimants—and for overhead costs. So long as an insurer maintains adequate funds set aside for anticipated losses (i.e., reserves), the remaining margin is an insurer's profit.
When is a Policy Really Insurance?
“Insurance provides indemnification against loss or liability from specified events and circumstances that may occur or be discovered during a specified period."
An operational definition of insurance is that it is:
The benefit provided by a particular kind of indemnity contract, called an insurance policy;
That is issued by one of several kinds of legal entities (stock company, mutual company, reciprocal, or Lloyd's syndicate, for example), any of which may be called an insurer;
In which the insurer promises to pay on behalf of or to indemnify another party, called a policyholder or insured;
That protects the insured against loss caused by those perils subject to the indemnity in exchange for consideration known as an insurance premium.
In recent years this kind of operational definition proved inadequate as a result of contracts that had the form but not the substance of insurance. The essence of insurance is the transfer of risk from the insured to one or more insurers. How much risk a contract actually transfers proved to be at the heart of the controversy.
This issue arose most clearly in reinsurance, where the use of Financial Reinsurance to reengineer insurer balance sheets under US GAAP became fashionable during the 1980s. The accounting profession raised serious concerns about the use of reinsurance in which little if any actual risk was transferred, and went on to address the issue in FAS 113, cited above. While on its face, FAS 113 is limited to accounting for reinsurance transactions, the guidance it contains is generally conceded to be equally applicable to US GAAP accounting for insurance transactions executed by commercial enterprises.
Does the Contract Contain Adequate Risk Transfer?
FAS 113 contains two tests, called the '9a and 9b tests,' that collectively require that a contract create a reasonable chance of a significant loss to the underwriter for it to be considered insurance.
Indemnification of the ceding enterprise against loss or liability relating to insurance risk in reinsurance of short-duration contracts requires both of the following, unless the condition in paragraph 11 is met:
The reinsurer assumes significant insurance risk under the reinsured portions of the underlying insurance contracts.
It is reasonably possible that the reinsurer may realize a significant loss from the transaction.
Paragraph 10 of FAS 113 makes clear that the 9a and 9b tests are based on comparing the present value of all costs to the PV of all income streams. FAS gives no guidance on the choice of a discount rate on which to base such a calculation, other than to say that all outcomes tested should use the same rate.
Statement of Statutory Accounting Principles ("SSAP") 62, issued by the National Association of Insurance Commissioners, applies to so-called 'statutory accounting' - the accounting for insurance enterprises to conform with regulation. Paragraph 12 of SSAP 62 is nearly identical to the FAS 113 test, while paragraph 14, which is otherwise very similar to paragraph 10 of FAS 113, additionally contains a justification for the use of a single fixed rate for discounting purposes. The choice of an "reasonable and appropriate" discount rate is left as a matter of judgment.
Is there a Brightline Test?
Neither FAS 113 nor SAP 62 defines the terms reasonable or significant. Ideally, one would like to be able to substitute values for both terms. It would be much simpler if one could apply a test of an X percent chance of a loss of Y percent or greater. Such tests have been proposed, including one famously attributed to an SEC official who is said to have opined in an after lunch talk that a 10 percent chance of a 10 percent loss was sufficient to establish both reasonableness and significance. Indeed, many insurers and reinsurers still apply this 10/10" test as a benchmark for risk transfer testing.
It should be obvious that an attempt to use any numerical rule such as the 10/10 test will quickly run into problems. Implicit in the test is keeping the 10/10 that either are upper bonds for the comment made by the SEC official therefore, the rest of this paragraph doesn't apply. Suppose a contract has a 1 percent chance of a 10,000 percent loss? It should be reasonably self-evident that such a contract is insurance, but it fails one half of the 10/10 test.It does not appear that any brightline test of reasonableness nor significance can be constructed.
Excess of loss contracts, like those commonly used for umbrella and general liability insurance, or to insure against property losses, will typically have a low ratio of premium paid to maximum loss recoverable. This ratio (expressed as a percentage), commonly called the rate on line for historical reasons related to underwriting practices at Lloyd's of London, will typically be low for contracts that contain reasonably self-evident risk transfer. As the ratio increases to approximate the present value of the limit of coverage, self-evidence decreases and disappears.
Contracts with low rates on line may survive modest features that limit the amount of risk transferred. As rates on line increase, such risk limiting features become increasingly important.
"Safe Harbor" Exemptions
The analysis of reasonableness and significance is an estimate of the probability of different gain or loss outcomes under different loss scenarios. It takes time and resources to perform the analysis, which constitutes a burden without value where risk transfer is reasonably self-evident.
Guidance exists for insurers and reinsurers, whose CEO's and CFO's attest annually as to the reinsurance agreements their firms undertake. The American Academy of Actuaries, for instance, identifies three categories of contract as outside the requirement of attestation:
Inactive contracts. If there are no premiums due nor losses payable, and the insurer is not taking any credit for the reinsurance, determining risk transfer is irrelevant.
Pre-1994 contracts. The attestation requirement only applies to contracts that were entered into, renewed or amended on or after 1 January 1994. Prior contracts need not be analyzed.
Where risk transfer is "reasonably self-evident."
"Risk transfer is reasonably self-evident in most traditional per-risk or per-occurrence excess of loss reinsurance contracts. For these contracts, a predetermined amount of premium is paid and the reinsurer assumes nearly all or all of the potential variability in the underlying losses, and it is evident from reading the basic terms of the contract that the reinsurer can incur a significant loss. In many cases, there is no aggregate limit on the reinsurer's loss. The existence of certain experience-based contract terms, such as experience accounts, profit commissions, and additional premiums, generally reduce the amount of risk transfer and make it less likely that risk transfer is reasonably self-evident."
Risk Limiting Features
An insurance policy should not contain provisions that allow one side or the other to unilaterally void the contract in exchange for benefit. Provisions that void the contract for failure to perform or for fraud or material misrepresentation are ordinary and acceptable.
The policy should have a term of not more than about three years. This is not a hard and fast rule. Contracts of over five years duration are classified as ‘long-term,’ which can impact the accounting treatment, and can obviously introduce the possibility that over the entire term of the contract, no actual risk will transfer. The coverage provided by the contract need not cease at the end of the term (e.g., the contract can cover occurrences as opposed to claims made or claims paid).
The contract should be considered to include any other agreements, written or oral, that confer rights, create obligations, or create benefits on the part of either or both parties. Ideally, the contract should contain an ‘Entire Agreement’ clause that assures there are no undisclosed written or oral side agreements that confer rights, create obligations, or create benefits on the part of either or both parties. If such rights, obligations or benefits exist, they must be factored into the tests of reasonableness and significance.
The contract should not contain arbitrary limitations on timing of payments. Provisions that assure both parties of time to properly present and consider claims are acceptable provided they are commercially reasonable and customary.
Provisions that expressly create actual or notional accounts that accrue actual or notional interest suggest that the contract contains, in fact, a deposit.
Provisions for additional or return premium do not, in and of themselves, render a contract something other than insurance. However, it should be unlikely that either a return or additional premium provision be triggered, and neither party should have discretion regarding the timing of such triggering.
All of the events that would give rise to claims under the contract cannot have materialized prior to the inception of the contract. If this "all events" test is not met, then the contract is considered to be a retroactive contract, for which the accounting treatment becomes complex.
Insurer’s Business Model
Profit = earned premium + investment income - incurred loss - underwriting expenses.
Insurers make money in two ways:
Through underwriting, the process by which insurers select the risks to insure and decide how much in premiums to charge for accepting those risks
By investing the premiums they collect from insureds.
The most difficult aspect of the insurance business is the underwriting of policies. Using a wide assortment of data, insurers predict the likelihood that a claim will be made against their policies and price products accordingly. To this end, insurers use actuarial science to quantify the risks they are willing to assume and the premium they will charge to assume them. Data is analyzed to fairly accurately project the rate of future claims based on a given risk. Actuarial science uses statistics and probability to analyze the risks associated with the range of perils covered, and these scientific principles are used to determine an insurer's overall exposure. Upon termination of a given policy, the amount of premium collected and the investment gains thereon minus the amount paid out in claims is the insurer's underwriting profit on that policy. Of course, from the insurer's perspective, some policies are winners (i.e., the insurer pays out less in claims and expenses than it receives in premiums and investment income) and some are losers (i.e., the insurer pays out more in claims and expenses than it receives in premiums and investment income).
An insurer's underwriting performance is measured in its combined ratio. The loss ratio (incurred losses and loss-adjustment expenses divided by net earned premium) is added to the expense ratio (underwriting expenses divided by net premium written) to determine the company's combined ratio. The combined ratio is a reflection of the company's overall underwriting profitability. A combined ratio of less than 100 percent indicates profitability, while anything over 100 indicates a loss.
Insurance companies also earn investment profits on “float”. “Float” or available reserve is the amount of money, at hand at any given moment, that an insurer has collected in insurance premiums but has not been paid out in claims. Insurers start investing insurance premiums as soon as they are collected and continue to earn interest on them until claims are paid out.
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, as 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, but this opinion is not universally held. Naturally, the “float” method is difficult to carry out in an economically depressed period. Bear markets do cause insurers to shift away from investments and to toughen up their underwriting standards. So a poor economy generally means high insurance premiums. This tendency to swing between profitable and unprofitable periods over time is commonly known as the "underwriting" or insurance cycle.
Property and casualty insurers currently make the most money from their auto insurance line of business. Generally better statistics are available on auto losses and underwriting on this line of business has benefited greatly from advances in computing. Additionally, property losses in the US, due to natural catastrophes, have exacerbated this trend.
Finally, claims and loss handling is the materialized utility of insurance. In managing the claims-handling function, insurers seek to balance the elements of customer satisfaction, administrative handling expenses, and claims overpayment leakages. As part of this balancing act, fraudulent insurance practices are a major business risk that must be managed and overcome.
Both gambling and insurance transfer risk and reward.Gambling transactions offer the possibility of either a loss or a gain. Gambling creates losers and winners. Insurance transactions do not present the possibility of gain. Insurance offers financial support sufficient to replace loss, not to create pure gain.
Gamblers can continue spending, buying more risk than they can afford to pay for. Insurance buyers can only spend up to the limit of what carriers would accept to insure; their loss is limited to the amount of the premium.
Gamblers, by creating new risk transfer, are risk seekers. Insurance buyers are risk avoiders, creating risk transfer in terms of their need to reduce exposure to large losses.
Gambling or gaming is designed at the start so that the odds are not affected by the players' conduct or behavior and not required to conduct risk mitigation practices. But players can prepare and increase their odds of winning in certain games such as poker or blackjack. In contrast to gambling or gaming, to obtain certain types of insurance, such as fire insurance, policyholders can be required to conduct risk mitigation practices, such as installing sprinklers and using fireproof building materials to reduce the odds of loss to fire. In addition, after a proven loss, insurers specialize in providing rehabilitation to minimize the total loss.
Insurance, the avoiding, mitigating and transferring of risk, creates greater predictability for individuals and organizations.
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 weighing 8.35-8.42) 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."
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
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.
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 home owner'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.
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 most of the United States an 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.
Aviation insurance insures against hull, spares, deductible, hull war 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.
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.
Casualty insurance insures against accidents, not necessarily tied to any specific property.
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 (which see below) 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.
Crime insurance insures 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."
Defense Base Act Workers' compensation or DBA Insurance insurance provides coverage for civilian workers hired by the government to perform contracts outside the US and Canada. DBA is required for all US citizens, US residents, US Green Card holders, and all employees or subcontractors hired on overseas government contracts. Depending on the country, Foreign Nationals must also be covered under DBA. This coverage typically includes expenses related to medical treatment and loss of wages, as well as disability and death benefits.
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.
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.
Errors and omissions insurance: See "Professional liability insurance" under "Liability insurance".
Expatriate insurance provides individuals and organizations operating outside of their home country with protection for automobiles, property, health, liability and business pursuits.
Financial loss insurance protects individuals and companies against various financial risks. For example, a business might purchase cover to protect it from loss of sales if a fire in a factory prevented it from carrying out its business for a time. Insurance might also cover the failure of a creditor to pay money it owes to the insured. This type of insurance is frequently referred to as "business interruption insurance." Fidelity bonds and surety bonds are included in this category, although these products provide a benefit to a third party (the "obligee") in the event the insured party (usually referred to as the "obligor") fails to perform its obligations under a contract with the obligee.
Hazard insurance: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.
Kidnap and ransom insurance
Home insurance or homeowners insurance: See "Property insurance".
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.
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.
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.
Locked funds insurance is a little-known hybrid insurance policy jointly issued by governments and banks. It is used to protect public funds from tamper by unauthorized parties. In special cases, a government may authorize its use in protecting semi-private funds which are liable to tamper. The terms of this type of insurance are usually very strict. Therefore it is used only in extreme cases where maximum security of funds is required.
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.
Mortgage insurance insures the lender against default by the borrower.
National Insurance is the UK's version of social insurance (which see below).
No-fault insurance is a type of insurance policy (typically automobile insurance) where insureds are indemnified by their own insurer regardless of fault in the incident.
Nuclear incident insurance covers damages resulting from an incident involving radioactive materials and is generally arranged at the national level. (For the United States, see the Price-Anderson Nuclear Industries Indemnity Act.)
Pet insurance insures pets against accidents and illnesses - some companies cover routine/wellness care and burial, as well.
Political risk insurance 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.
Pollution Insurance. A first-party coverage for contamination of insured property either by external or on-site sources. Coverage for liability to third parties arising from contamination of air, water, or land due to the sudden and accidental release of hazardous materials from the insured site. The policy usually covers the costs of cleanup and may include coverage for releases from underground storage tanks. Intentional acts are specifically excluded
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.
Purchase insurance is aimed at providing protection on the products people purchase. Purchase insurance can cover individual purchase protection, warranties, guarantees, care plans and even mobile phone insurance. Such insurance is normally very limited in the scope of problems that are covered by the policy.
Retrospectively Rated Insurance is a method of establishing a premium on large commercial accounts. The final premium is based on the insured's actual loss experience during the policy term, sometimes subject to a minimum and maximum premium, with the final premium determined by a formula. Under this plan, the current year's premium is based partially (or wholly) on the current year's losses, although the premium adjustments may take months or years beyond the current year's expiration date. The rating formula is guaranteed in the insurance contract. Formula: retrospective premium = converted loss + basic premium × tax multiplier. Numerous variations of this formula have been developed and are in use.
Social insurance can be many things to many people in many countries. But a summary of its essence is that it is a collection of insurance coverages (including components of life insurance, disability income insurance, unemployment insurance, health insurance, and others), plus retirement savings, that mandates participation by all citizens. By forcing everyone in society to be a policyholder and pay premiums, it ensures that everyone can become a claimant when or if he/she needs to. Along the way this inevitably becomes related to other concepts such as the justice system and the welfare state. This is a large, complicated topic that engenders tremendous debate, which can be further studied in the following articles (and others):

Types of Insurance Companies
Insurance companies may be classified as:
Life insurance companies, which sell life insurance, annuities and pensions products.
Non-life or general insurance companies, which sell other types of insurance.
General insurance companies can be further divided into these sub categories.
In most countries, life and non-life insurers are subject to different regulatory regimes and different tax and accounting rules. The main reason for the distinction between the two types of company is that life, annuity, and pension business is very long-term in nature — coverage for life assurance or a pension can cover risks over many decades. By contrast, non-life insurance cover usually covers a shorter period, such as one year.
In the United States, standard line insurance companies are your "main stream" insurers. These are the companies that typically insure your auto, home or business. They use pattern or "cookie cutter" policies without variation from one person to the next. They usually have lower premiums than excess lines and can sell directly to individuals. They are regulated by state laws that can restrict the amount they can charge for insurance policies.
Excess line insurance companies (aka Excess and Surplus) typically insure risks not covered by the standard lines market. They are broadly referred as being all insurance placed with non-admitted insurers. Non-admitted insurers are not licensed in the states where the risks are located. These companies have more flexibility and can react faster than standard insurance companies because they don't have the same regulations as standard insurance companies. State laws generally require insurance placed with surplus line agents and brokers to not be available through standard licensed insurers.
Insurance companies are generally classified as either mutual or stock companies. This is more of a traditional distinction as true mutual companies are becoming rare. Mutual companies are owned by the policyholders, while stockholders (who may or may not own policies) own stock insurance companies. Other possible forms for an insurance company include reciprocals, in which policyholders 'reciprocate' in sharing risks, and Lloyds organizations.
Insurance companies are rated by various agencies such as A.M. Best. The ratings include the company's financial strength, which measures its ability to pay claims. It also rates financial instruments issued by the insurance company, such as bonds, notes, and securitization products.
Reinsurance companies are insurance companies that sell policies to other insurance companies, allowing them to reduce their risks and protect themselves from very large losses. The reinsurance market is dominated by a few very large companies, with huge reserves. A reinsurer may also be a direct writer of insurance risks as well.
Captive insurance companies may be defined as limited-purpose insurance companies established with the specific objective of financing risks emanating from their parent group or groups. This definition can sometimes be extended to include some of the risks of the parent company's customers. In short, it is an in-house self-insurance vehicle. Captives may take the form of a "pure" entity (which is a 100 percent subsidiary of the self-insured parent company); of a "mutual" captive (which insures the collective risks of members of an industry); and of an "association" captive (which self-insures individual risks of the members of a professional, commercial or industrial association). Captives represent commercial, economic and tax advantages to their sponsors because of the reductions in costs they help create and for the ease of insurance risk management and the flexibility for cash flows they generate. Additionally, they may provide coverage of risks which is neither available nor offered in the traditional insurance market at reasonable prices.
The types of risk that a captive can underwrite for their parents include property damage, public and products liability, professional indemnity, employee benefits, employers liability, motor and medical aid expenses. The captive's exposure to such risks may be limited by the use of reinsurance.
Captives are becoming an increasingly important component of the risk management and risk financing strategy of their parent. This can be understood against the following background:
Heavy and increasing premium costs in almost every line of coverage;
Difficulties in insuring certain types of fortuitous risk;
Differential coverage standards in various parts of the world;
Rating structures which reflect market trends rather than individual loss experience;
Insufficient credit for deductibles and/or loss control efforts.
There are also companies known as 'insurance consultants'. Like a mortgage broker, these companies are paid a fee by the customer to shop around for the best insurance policy amongst many companies .
Similar to an insurance consultant, an 'insurance broker' also shops around for the best insurance policy amongst many companies. However, with insurance brokers, the fee is usually paid in the form of commission from the insurer that is selected rather than directly from the client.
Neither insurance consultants nor insurance brokers are insurance companies and no risks are transferred to them in insurance transactions.
Third party administrators are companies that perform underwriting and sometimes claims handling services for insurance companies. These companies often have special expertise that the insurance companies do not have.
Life Insurance and Saving
Certain life insurance contracts accumulate cash values, which may be taken by the insured if the policy is surrendered or which may be borrowed against. Some policies, such as annuities and endowment policies, are financial instruments to accumulate or liquidate wealth when it is needed. See life insurance.
In many countries, such as the U.S. and the UK, the tax law provides that the interest on this cash value is not taxable under certain circumstances. This leads to widespread use of life insurance as a tax-efficient method of saving as well as protection in the event of early death.
In U.S., the tax on interest income on life insurance policies and annuities is generally deferred. However, in some cases the benefit derived from tax deferral may be offset by a low return. This depends upon the insuring company, the type of policy and other variables (mortality, market return, etc.). Moreover, other income tax saving vehicles (e.g., IRAs, 401(k) plans, Roth IRAs) may be better alternatives for value accumulation. A combination of low-cost term life insurance and a higher-return tax-efficient retirement account may achieve better investment return.
Size of Global Insurance Industry
Global insurance premiums grew by 9.7 percent in 2004 to reach $3.3 trillion. This follows 11.7 percent growth in the previous year. Life insurance premiums grew by 9.8 percent during the year, thanks to rising demand for annuity and pension products. Non-life insurance premiums grew by 9.4 percent, as premium rates increased. Over the past decade, global insurance premiums rose by more than a half as annual growth fluctuated between 2 percent and 10 percent. 
Advanced economies account for the bulk of global insurance. With premium income of $1,217 billion in 2004, North America was the most important region, followed by the EU (at $1,198 billion) and Japan (at $492 billion). The top four countries accounted for nearly two-thirds of premiums in 2004. The United States and Japan alone accounted for a half of world insurance premiums, much higher than their 7 percent share of the global population. Emerging markets accounted for over 85 percent of the world’s population but generated only 10 percent of premiums. The volume of UK insurance business totaled $295 billion in 2004 or 9.1 percent of global premiums.
Financial Viability of Insurance Companies
Financial stability and strength of an insurance company should be a major consideration when purchasing an insurance contract. An insurance premium paid currently provides coverage for losses that might arise many years in the future. For that reason, the viability of the insurance carrier is very important. In recent years, a number of insurance companies have become insolvent, leaving their policyholders with no coverage (or coverage only from a government-backed insurance pool or other arrangement with less attractive payouts for losses). A number of independent rating agencies, such as Best's, Fitch, Standard & Poor's, and Moody's Investors Service, provide information and rate the financial viability of insurance companies.
Insurance Insulates Too Much
By creating a "security blanket" for its insureds, an insurance company may inadvertently find that its insureds may not be as risk-averse as they might otherwise be (since, by definition, the insured has transferred the risk to the insurer). This problem is known to the insurance industry as moral hazard. To reduce their own financial exposure, insurance companies have contractual clauses that mitigate their obligation to provide coverage if the insured engages in behavior that grossly magnifies their risk of loss or liability.
For example, life insurance companies may require higher premiums or deny coverage altogether to people who work in hazardous occupations or engage in dangerous sports. Liability insurance providers do not provide coverage for liability arising from intentional torts committed by the insured. Even if a provider were so irrational as to desire to provide such coverage, it is against the public policy of most countries to allow such insurance to exist, and thus it is usually illegal.
Closed Community Self-Insurance
Some communities prefer to create virtual insurance amongst themselves by other means than contractual risk transfer, which assigns explicit numerical values to risk. A number of religious groups, including the Amish and some Muslim groups, depend on support provided by their communities when disasters strike. The risk presented by any given person is assumed collectively by the community who all bear the cost of rebuilding lost property and supporting people whose needs are suddenly greater after a loss of some kind. In supportive communities where others can be trusted to follow community leaders, this tacit form of insurance can work. In this manner the community can even out the extreme differences in insurability that exist among its members. Some further justification is also provided by invoking the moral hazard of explicit insurance contracts.
In the United Kingdom The Crown (which, for practical purposes, meant the Civil service) did not insure property such as government buildings. If a government building was damaged, the cost of repair would be met from public funds because, in the long run, this was cheaper than paying insurance premiums. Since many UK government buildings have been sold to property companies, and rented back, this arrangement is now less common and may have disappeared altogether.
Complexity of Insurance Policy Contracts
Insurance policies can be complex and some policyholders may not understand all the fees and coverages included in a policy. As a result, people may buy policies on unfavorable terms. In response to these issues, many countries have enacted detailed statutory and regulatory regimes governing every aspect of the insurance business, including minimum standards for policies and the ways in which they may be advertised and sold.
Many institutional insurance purchasers buy insurance through an insurance broker. Brokers represent the buyer (not the insurance company), and typically counsel the buyer on appropriate coverages, policy limitations. A broker generally holds contracts with many insurers, thereby allowing the broker to "shop" the market for the best rates and coverage possible.
Insurance may also be purchased through an agent. Unlike a broker, who represents the policyholder, an agent represents the insurance company from whom the policyholder buys. An agent can represent more than one company.
Redlining is the practice of denying insurance coverage in specific geographic areas, purportedly because of a high likelihood of loss, while the alleged motivation is unlawful discrimination.
In determining premiums and premium rate structures, insurers consider quantifiable factors, including location, credit scores, gender, occupation, marital status, and education level. However, the use of such factors is often considered to be unfair or unlawfully discriminatory, and the reaction against this practice has in some instances led to political disputes about the ways in which insurers determine premiums and regulatory intervention to limit the factors used.
An insurance underwriter's job is to evaluate a given risk as to the likelihood that a loss will occur. Any factor that causes a greater likelihood of loss should theoretically be charged a higher rate. This basic principle of insurance must be followed if insurance companies are to remain solvent. Thus, "discrimination" against (i.e., differential treatment of) potential insureds in the risk evaluation and premium-setting process is a necessary by-product of the fundamentals of insurance underwriting. For instance, insurers charge older people significantly higher premiums than they charge younger people for term life insurance. Older people are thus treated differently than younger people (i.e., a distinction is made, discrimination occurs). The rationale for the differential treatment goe
