Insurance is the equitable transfer of the risk of a loss, from one entity to another in exchange for payment. It is a form of risk management primarily used to hedge against the risk of a contingent, uncertain loss.
An insurer, or insurance carrier, is a company selling the insurance; the insured, or policyholder, is the person or entity buying the insurance policy. The amount of money to be charged for a certain amount of insurance coverage is called the premium. Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study and practice.
The transaction involves the insured assuming a guaranteed and known relatively small loss in the form of payment to the insurer in exchange for the insurer's promise to compensate (indemnify) the insured in the case of a financial (personal) loss. The insured receives a contract, called the insurance policy, which details the conditions and circumstances under which the insured will be financially compensated.
Insurance involves pooling funds from many insured entities (known as exposures) to pay for the losses that some may incur. The insured entities are therefore protected from risk for a fee, with the fee being dependent upon the frequency and severity of the event occurring. In order to be an insurable risk, the risk insured against must meet certain characteristics. Insurance as a financial intermediary is a commercial enterprise and a major part of the financial services industry, but individual entities can also self-insure through saving money for possible future losses.
Risk which can be insured by private companies typically shares seven common characteristics:
- Large number of similar exposure units: Since insurance operates through pooling resources, the majority of insurance policies are provided for individual members of large classes, allowing insurers to benefit from the law of large numbers in which predicted losses are similar to the actual losses. Exceptions include Lloyd's of London, which is famous for insuring the life or health of actors, sports figures, and other famous individuals. However, all exposures will have particular differences, which may lead to different premium rates.
- Definite loss: The loss takes place at a known time, in a known place, and from a known cause. The classic example is death of an insured person 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.
- 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 or even purchasing a lottery ticket, are generally not considered insurable.
- 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 hardly any point in paying such costs unless the protection offered has real value to a buyer.
- 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, then it is not likely that the insurance will be purchased, even if on offer. Furthermore, 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, then the transaction may have the form of insurance, but not the substance. (See the US Financial Accounting Standards Board standard number 113)
- 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.
- Limited risk of catastrophically large losses: Insurable losses are ideally independent and non-catastrophic, meaning that the losses do not happen all at once and individual losses are not severe enough to bankrupt the insurer; insurers may prefer to limit their exposure to a loss from a single event to some small portion of their capital base. Capital constrains insurers' ability to sell earthquake insurance as well as wind insurance in hurricane zones. In the US, flood risk is insured by the federal government. 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.
When a company insures an individual entity, there are basic legal requirements. Several commonly cited legal principles of insurance include:
- Indemnity – the insurance company indemnifies, or compensates, the insured in the case of certain losses only up to the insured's interest.
- Insurable interest – the insured typically must directly suffer from the loss. Insurable interest must exist whether property insurance or insurance on a person is involved. The concept requires that the insured have a "stake" in the loss or damage to the life or property insured. What that "stake" is will be determined by the kind of insurance involved and the nature of the property ownership or relationship between the persons. The requirement of an insurable interest is what distinguishes insurance from gambling.
- Utmost good faith – (Uberrima fides) the insured and the insurer are bound by a good faith bond of honesty and fairness. Material facts must be disclosed.
- Contribution – insurers which have similar obligations to the insured contribute in the indemnification, according to some method.
- Subrogation – the insurance company acquires legal rights to pursue recoveries on behalf of the insured; for example, the insurer may sue those liable for the insured's loss.
- Causa proxima, or proximate cause – the cause of loss (the peril) must be covered under the insuring agreement of the policy, and the dominant cause must not be excluded
- Mitigation - In case of any loss or casualty, the asset owner must attempt to keep loss to a minimum, as if the asset was not insured.
To "indemnify" means to make whole again, or to be reinstated to the position that one was in, to the extent possible, prior to the happening of a specified event or peril. Accordingly, life insurance is generally not considered to be indemnity insurance, but rather "contingent" insurance (i.e., a claim arises on the occurrence of a specified event). There are generally three types of insurance contracts that seek to indemnify an insured:
- a "reimbursement" policy, and
- a "pay on behalf" or "on behalf of" policy, and
- an "indemnification" policy.
From an insured's standpoint, the result is usually the same: the insurer pays the loss and claims expenses.
If the Insured has a "reimbursement" policy, the insured can be required to pay for a loss and then be "reimbursed" by the insurance carrier for the loss and out of pocket costs including, with the permission of the insurer, claim expenses.
Under a "pay on behalf" policy, the insurance carrier would defend and pay a claim on behalf of the insured who would not be out of pocket for anything. Most modern liability insurance is written on the basis of "pay on behalf" language which enables the insurance carrier to manage and control the claim.
Under an "indemnification" policy, the insurance carrier can generally either "reimburse" or "pay on behalf of", whichever is more beneficial to it and the insured in the claim handling process.
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: identification of participating 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 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 (called reserves), the remaining margin is an insurer's profit.
Societal effects 
Insurance can have various effects on society through the way that it changes who bears the cost of losses and damage. On one hand it can increase fraud; on the other it can help societies and individuals prepare for catastrophes and mitigate the effects of catastrophes on both households and societies.
Insurance can influence the probability of losses through moral hazard, insurance fraud, and preventive steps by the insurance company. Insurance scholars have typically used morale hazard to refer to the increased loss due to unintentional carelessness and moral hazard to refer to increased risk due to intentional carelessness or indifference. Insurers attempt to address carelessness through inspections, policy provisions requiring certain types of maintenance, and possible discounts for loss mitigation efforts. While in theory insurers could encourage investment in loss reduction, some commentators have argued that in practice insurers had historically not aggressively pursued loss control measures—particularly to prevent disaster losses such as hurricanes—because of concerns over rate reductions and legal battles. However, since about 1996 insurers have begun to take a more active role in loss mitigation, such as through building codes.
Insurers' business model 
Underwriting and investing 
The business model is to collect more in premium and investment income than is paid out in losses, and to also offer a competitive price which consumers will accept. Profit can be reduced to a simple equation:
- 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 insured parties.
The most complicated aspect of the insurance business is the actuarial science of ratemaking (price-setting) of policies, which uses statistics and probability to approximate the rate of future claims based on a given risk. After producing rates, the insurer will use discretion to reject or accept risks through the underwriting process.
At the most basic level, initial ratemaking involves looking at the frequency and severity of insured perils and the expected average payout resulting from these perils. Thereafter an insurance company will collect historical loss data, bring the loss data to present value, and compare these prior losses to the premium collected in order to assess rate adequacy. Loss ratios and expense loads are also used. Rating for different risk characteristics involves at the most basic level comparing the losses with "loss relativities" - a policy with twice as many losses would therefore be charged twice as much. More complex multivariate analyses are sometimes used when multiple characteristics are involved and a univariate analysis could produce confounded results. Other statistical methods may be used in assessing the probability of future losses.
Upon termination of a given policy, the amount of premium collected minus the amount paid out in claims is the insurer's underwriting profit on that policy. Underwriting performance is measured by something called the "combined ratio" which is the ratio of expenses/losses to premiums. A combined ratio of less than 100 percent indicates an underwriting profit, while anything over 100 indicates an underwriting loss. A company with a combined ratio over 100% may nevertheless remain profitable due to investment earnings.
Insurance companies earn investment profits on "float". Float, or available reserve, is the amount of money on hand at any given moment that an insurer has collected in insurance premiums but has not paid out in claims. Insurers start investing insurance premiums as soon as they are collected and continue to earn interest or other income on them until claims are paid out. The Association of British Insurers (gathering 400 insurance companies and 94% of UK insurance services) has almost 20% of the investments in the London Stock Exchange.
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.
Claims and loss handling is the materialized utility of insurance; it is the actual "product" paid for. Claims may be filed by insureds directly with the insurer or through brokers or agents. The insurer may require that the claim be filed on its own proprietary forms, or may accept claims on a standard industry form, such as those produced by ACORD.
Insurance company claims departments employ a large number of claims adjusters supported by a staff of records management and data entry clerks. Incoming claims are classified based on severity and are assigned to adjusters whose settlement authority varies with their knowledge and experience. The adjuster undertakes an investigation of each claim, usually in close cooperation with the insured, determines if coverage is available under the terms of the insurance contract, and if so, the reasonable monetary value of the claim, and authorizes payment.
The policyholder may hire their own public adjuster to negotiate the settlement with the insurance company on their behalf. For policies that are complicated, where claims may be complex, the insured may take out a separate insurance policy add on, called loss recovery insurance, which covers the cost of a public adjuster in the case of a claim.
Adjusting liability insurance claims is particularly difficult because there is a third party involved, the plaintiff, who is under no contractual obligation to cooperate with the insurer and may in fact regard the insurer as a deep pocket. The adjuster must obtain legal counsel for the insured (either inside "house" counsel or outside "panel" counsel), monitor litigation that may take years to complete, and appear in person or over the telephone with settlement authority at a mandatory settlement conference when requested by the judge.
If a claims adjuster suspects under-insurance, the condition of average may come into play to limit the insurance company's exposure.
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. Disputes between insurers and insureds over the validity of claims or claims handling practices occasionally escalate into litigation (see insurance bad faith).
Insurers will often use insurance agents to initially market or underwrite their customers. Agents can be captive, meaning they write only for one company, or independent, meaning that they can issue policies from several companies. The existence and success of companies using insurance agents is likely due to improved and personalized service.
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: natural or non-monetary economies (using barter and trade with no centralized nor standardized set of financial instruments) and more modern monetary economies (with markets, currency, financial instruments and so on). The former is more primitive and the insurance in such economies entails agreements of mutual aid. If one family's house is destroyed the neighbours are committed to help rebuild. Granaries housed another primitive form of insurance to indemnify against famines. Often informal or formally intrinsic to local religious customs, this type of insurance has survived to the present day in some countries where a modern money economy with its financial instruments is not widespread.
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 or lost at sea.
Achaemenian monarchs of Ancient Persia 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."
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 deliberately jettisoned in order to lighten the ship and save it from total loss.
The ancient Athenian "maritime loan" advanced money for voyages with repayment being cancelled if the ship was lost. In the 4th century BC, rates for the loans differed according to safe or dangerous times of year, implying an intuitive pricing of risk with an effect similar to insurance. The Greeks and Romans introduced the origins of health and life insurance c. 600 BCE when they created guilds called "benevolent societies" which cared for the families of deceased members, as well as paying funeral expenses of members. 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.
Some forms of insurance had developed in London by the early decades of the 17th century. For example, the will of the English colonist Robert Hayman mentions two "policies of insurance" taken out with the diocesan Chancellor of London, Arthur Duck. Of the value of £100 each, one relates to the safe arrival of Hayman's ship in Guyana and the other is in regard to "one hundred pounds assured by the said Doctor Arthur Ducke on my life". Hayman's will was signed and sealed on 17 November 1628 but not proved until 1633. 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, 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 an insurance market rather than a company) for marine and other specialist types of insurance, but it operates 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 more than 13,000 houses. The devastating effects of the fire converted the development of insurance "from a matter of convenience into one of urgency, a change of opinion reflected in Sir Christopher Wren's inclusion of a site for 'the Insurance Office' in his new plan for London in 1667." A number of attempted fire insurance schemes came to nothing, but in 1681 Nicholas Barbon, and eleven associates, established England's first fire insurance company, the 'Insurance Office for Houses', at the back of the Royal Exchange. Initially, 5,000 homes were insured by Barbon's Insurance Office.
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 primary resides with individual state insurance departments. The current state insurance regulatory framework has its roots in the 19th century, when New Hampshire appointed the first insurance commissioner in 1851. Congress adopted the McCarran-Ferguson Act in 1945, which declared that states should regulate the business of insurance and to affirm that the continued regulation of the insurance industry by the states is in the public's best interest. The Financial Modernization Act of 1999, commonly referred to as "Gramm-Leach-Bliley", established a comprehensive framework to authorize affiliations between banks, securities firms, and insurers, and once again acknowledged that states should regulate insurance.
Whereas insurance markets have become centralized nationally and internationally, state insurance commissioners operate individually, though at times in concert through the National Association of Insurance Commissioners. In recent years, some have called for a dual state and federal regulatory system (commonly referred to as the Optional federal charter (OFC)) for insurance similar to the banking industry.
In 2010, the federal Dodd-Frank Wall Street Reform and Consumer Protection Act established the Federal Insurance Office ("FIO"). FIO is part of the U.S. Department of the Treasury and it monitors all aspects of the insurance industry, including identifying issues or gaps in the regulation of insurers that may contribute to a systemic crisis in the insurance industry or in the U.S. financial system. FIO coordinates and develops federal policy on prudential aspects of international insurance matters, including representing the U.S. in the International Association of Insurance Supervisors. FIO also assists the U.S. Secretary of Treasury with negotiating (with the U.S. Trade Representative) certain international agreements.
Moreover, FIO monitors access to affordable insurance by traditionally underserved communities and consumers, minorities, and low- and moderate-income persons. The Office also assists the U.S. Secretary of the Treasury with administering the Terrorism Risk Insurance Program. However, FIO is not a regulator or supervisor. The regulation of insurance continues to reside with the states.
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, vehicle insurance would typically cover both the property risk (theft or damage to the vehicle) and the liability risk (legal claims arising from an accident). A home insurance policy in the US typically includes coverage for damage to the home and the owner's belongings, 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 take a number of different forms, such as the various kinds of professional liability insurance, also called professional indemnity (PI), which are discussed below under that name; and the business owner's policy (BOP), which packages into one policy many of the kinds of coverage that a business owner needs, in a way analogous to how homeowners' insurance packages the coverages that a homeowner needs.
Auto insurance 
Auto insurance protects the policyholder against financial loss in the event of an incident involving a vehicle they own, such as in a traffic collision.
Coverage typically includes:
- Property coverage, for damage to or theft of the car;
- Liability coverage, for the legal responsibility to others for bodily injury or property damage;
- Medical coverage, for the cost of treating injuries, rehabilitation and sometimes lost wages and funeral expenses.
Most countries, such as the United Kingdom, require drivers to buy some, but not all, of these coverages. When a car is used as collateral for a loan the lender usually requires specific coverage.
Gap insurance 
Gap insurance covers the excess amount on your auto loan in an instance where your insurance company does not cover the entire loan. Depending on the companies specific policies it might or might not cover the deductible as well. This coverage is marketed for those who put low down payments, have high interest rates on their loans, and those with 60 month or longer terms. Gap insurance is typically offered by your finance company when you first purchase your vehicle. Most auto insurance companies offer this coverage to consumers as well. If you are unsure if GAP coverage had been purchased, you should check your vehicle lease or purchase documentation.
Health insurance 
Health insurance policies cover the cost of medical treatments. Dental insurance, like medical insurance protects policyholders for dental costs. In the US and Canada, dental insurance is often part of an employer's benefits package, along with health insurance.
Accident, sickness and unemployment insurance 
- Disability insurance policies provide financial support in the event of the policyholder becoming unable to work because of disabling illness or injury. It provides monthly support to help pay such obligations as mortgage loans and credit cards. Short-term and long-term disability policies are available to individuals, but considering the expense, long-term policies are generally obtained only by those with at least six-figure incomes, such as doctors, lawyers, etc. Short-term disability insurance covers a person for a period typically up to six months, paying a stipend each month to cover medical bills and other necessities.
- Long-term disability insurance covers an individual's expenses for the long term, up until such time as they are considered permanently disabled and thereafter. Insurance companies will often try to encourage the person back into employment in preference to and before declaring them unable to work at all and therefore totally disabled.
- Disability overhead insurance allows business owners to cover the overhead expenses of their business while they are unable to work.
- Total permanent disability 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.
- Workers' compensation insurance replaces all or part of a worker's wages lost and accompanying medical expenses incurred because of a job-related injury.
Casualty insurance insures against accidents, not necessarily tied to any specific property. It is a broad spectrum of insurance that a number of other types of insurance could be classified, such as auto, workers compensation, and some liability insurances.
- 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.
- 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 could result in a loss.
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. In most states, a person cannot purchase a policy on another person without their knowledge.
Annuities provide a stream of payments and are generally classified as insurance because they are issued by insurance companies, are 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.
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.
In many countries, such as the US 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 the US, 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.
Burial insurance 
Burial insurance is a very old type of life insurance which is paid out upon death to cover final expenses, such as the cost of a funeral. The Greeks and Romans introduced burial insurance circa 600 CE when they organized guilds called "benevolent societies" which cared for the surviving families and paid funeral expenses of members upon death. Guilds in the Middle Ages served a similar purpose, as did friendly societies during Victorian times.
Property insurance provides protection against risks to property, such as fire, theft or weather damage. This may include specialized forms of insurance such as fire insurance, flood insurance, earthquake insurance, home insurance, inland marine insurance or boiler insurance. The term property insurance may, like casualty insurance, be used as a broad category of various subtypes of insurance, some of which are listed below:
- Aviation insurance protects aircraft hulls and spares, and associated liability risks, such as passenger and third-party liability. Airports may also appear under this subcategory, including air traffic control and refuelling operations for international airports through to smaller domestic exposures.
- Boiler insurance (also known as boiler and machinery insurance, or equipment breakdown insurance) insures against accidental physical damage to boilers, 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 arising from any cause (including the negligence of the insured) not otherwise expressly excluded. Builder's risk insurance is coverage that protects a person's or organization's insurable interest in materials, fixtures and/or equipment being used in the construction or renovation of a building or structure should those items sustain physical loss or damage from an insured peril.
- Crop insurance may be purchased by farmers 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.
- 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 home insurance policies do not cover earthquake damage. Earthquake insurance policies generally feature a high deductible. Rates depend on location and hence the likelihood of an earthquake, as well as the construction of the home.
- Fidelity bond is a form of casualty insurance that covers policyholders for losses incurred as a result of fraudulent acts by specified individuals. It usually insures a business for losses caused by the dishonest acts of its employees.
- Flood insurance protects against property loss due to flooding. Many insurers in the US do not provide flood insurance in some parts of the country. In response to this, the federal government created the National Flood Insurance Program which serves as the insurer of last resort.
- Home insurance, also commonly called hazard insurance or homeowners insurance (often abbreviated in the real estate industry as HOI), provides coverage for damage or destruction of the policyholder's home. In some geographical areas, the policy may exclude certain types of risks, such as flood or earthquake, that require additional coverage. Maintenance-related issues are typically the homeowner's 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.
- Landlord insurance covers residential and commercial properties which are rented to others. Most homeowners' insurance covers only owner-occupied homes.
- Marine insurance and marine cargo insurance cover the loss or damage of vessels at sea or on inland waterways, and of cargo in transit, regardless of the method of transit. 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.
- Supplemental natural disaster insurance covers specified expenses after a natural disaster renders the policyholder's home uninhabitable. Periodic payments are made directly to the insured until the home is rebuilt or a specified time period has elapsed.
- 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. In the US in the wake of 9/11, the Terrorism Risk Insurance Act 2002 (TRIA) set up a federal Program providing a transparent system of shared public and private compensation for insured losses resulting from acts of terrorism. The program was extended until the end of 2014 by the Terrorism Risk Insurance Program Reauthorization Act 2007 (TRIPRA).
- Volcano insurance is a specialized insurance protecting against damage arising specifically from volcanic eruptions.
- Windstorm insurance is an insurance covering the damage that can be caused by wind events such as hurricanes.
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 wilful or intentional acts by the insured.
- Public liability insurance covers a business or organization against claims should its operations injure a member of the public or damage their property in some way.
- Directors and officers liability insurance (D&O) protects an organization (usually a corporation) from costs associated with litigation resulting from errors made by directors and officers for which they are liable.
- 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 (E&O) is business liability insurance for professionals such as insurance agents, real estate agents and brokers, architects, third-party administrators (TPAs) and other business professionals.
- 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.
- Professional liability insurance, also called professional indemnity insurance (PI), protects insured professionals such as architectural corporations and medical practitioners 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 medical malpractice insurance.
- Mortgage insurance insures the lender against default by the borrower. 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.
- Many credit cards offer payment protection plans which are a form of credit insurance.
- Trade credit insurance is business insurance over the accounts receivable of the insured. The policy pays the policy holder for covered accounts receivable if the debtor defaults on payment.
Other types 
- All-risk insurance is an insurance that covers a wide range of incidents and perils, except those noted in the policy. All-risk insurance is different from peril-specific insurance that cover losses from only those perils listed in the policy. In car insurance, all-risk policy includes also the damages caused by the own driver.
- Bloodstock insurance covers individual horses or a number of horses under common ownership. Coverage is typically for mortality as a result of accident, illness or disease but may extend to include infertility, in-transit loss, veterinary fees, and prospective foal.
- Business interruption insurance covers the loss of income, and the expenses incurred, after a covered peril interrupts normal business operations.
- Collateral protection insurance (CPI) insures property (primarily vehicles) held as collateral for loans made by lending institutions.
- Defense Base Act (DBA) 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.
- Expatriate insurance provides individuals and organizations operating outside of their home country with protection for automobiles, property, health, liability and business pursuits.
- Kidnap and ransom insurance is designed to protect individuals and corporations operating in high-risk areas around the world against the perils of kidnap, extortion, wrongful detention and hijacking.
- Legal expenses insurance covers policyholders for the potential costs of legal action against an institution or an individual. When something happens which triggers the need for legal action, it is known as "the event". There are two main types of legal expenses insurance: before the event insurance and after the event insurance.
- Livestock insurance is a specialist policy provided to, for example, commercial or hobby farms, aquariums, fish farms or any other animal holding. Cover is available for mortality or economic slaughter as a result of accident, illness or disease but can extend to include destruction by government order.
- Media liability insurance is designed to cover professionals that engage in film and television production and print, against risks such as defamation.
- Nuclear incident insurance covers damages resulting from an incident involving radioactive materials and is generally arranged at the national level. (See the nuclear exclusion clause and for the US 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.
- Pollution insurance usually takes the form of first-party coverage for contamination of insured property either by external or on-site sources. Coverage is also afforded 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.
- 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.
- Title insurance provides a guarantee that title to real property is vested in the purchaser and/or mortgagee, free and clear of liens or encumbrances. It is usually issued in conjunction with a search of the public records performed at the time of a real estate transaction.
- Travel insurance is an insurance cover taken by those who travel abroad, which covers certain losses such as medical expenses, loss of personal belongings, travel delay, and personal liabilities.
- Tuition insurance insures students against involuntary withdrawal from cost-intensive educational institutions
- Interest rate insurance protects the holder from adverse changes in interest rates, for instance for those with a variable rate loan or mortgage
Insurance financing vehicles 
- Fraternal insurance is provided on a cooperative basis by fraternal benefit societies or other social organizations.
- 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.
- Protected self-insurance is an alternative risk financing mechanism in which an organization retains the mathematically calculated cost of risk within the organization and transfers the catastrophic risk with specific and aggregate limits to an insurer so the maximum total cost of the program is known. A properly designed and underwritten Protected Self-Insurance Program reduces and stabilizes the cost of insurance and provides valuable risk management information.
- 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.
- Formal self-insurance is the deliberate decision to pay for otherwise insurable losses out of one's own money. This can be done on a formal basis by establishing a separate fund into which funds are deposited on a periodic basis, or by simply forgoing the purchase of available insurance and paying out-of-pocket. Self-insurance is usually used to pay for high-frequency, low-severity losses. Such losses, if covered by conventional insurance, mean having to pay a premium that includes loadings for the company's general expenses, cost of putting the policy on the books, acquisition expenses, premium taxes, and contingencies. While this is true for all insurance, for small, frequent losses the transaction costs may exceed the benefit of volatility reduction that insurance otherwise affords.
- Reinsurance is a type of insurance purchased by insurance companies or self-insured employers to protect against unexpected losses. Financial reinsurance is a form of reinsurance that is primarily used for capital management rather than to transfer insurance risk.
- 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 requires 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):
- Stop-loss insurance provides protection against catastrophic or unpredictable losses. It is purchased by organizations who do not want to assume 100% of the liability for losses arising from the plans. Under a stop-loss policy, the insurance company becomes liable for losses that exceed certain limits called deductibles.
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.
Insurance companies 
Insurance companies may be classified into two groups:
- Life insurance companies, which sell life insurance, annuities and pensions products.
- Non-life, general, or property/casualty insurance companies, which sell other types of insurance.
General insurance companies can be further divided into these sub categories.
- Standard lines
- Excess lines
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 insurers that have received a license or authorization from a state for the purpose of writing specific kinds of insurance in that state, such as automobile insurance or homeowners' insurance. They are typically referred to as "admitted" insurers. Generally, such an insurance company must submit its rates and policy forms to the state's insurance regulator to receive his or her prior approval, although whether an insurance company must receive prior approval depends upon the kind of insurance being written. Standard line insurance companies usually charge lower premiums than excess line insurers and may sell directly to individual insureds. They are regulated by state laws, which include restrictions on rates and forms, and which aim to protect consumers and the public from unfair or abusive practices. These insurers also are required to contribute to state guarantee funds, which are used to pay for losses if an insurer becomes insolvent.
Excess line insurance companies (also known as Excess and Surplus) typically insure risks not covered by the standard lines insurance market, due to a variety of reasons (e.g., new entity or an entity that does not have an adequate loss history, an entity with unique risk characteristics, or an entity that has a loss history that does not fit the underwriting requirements of the standard lines insurance market). They are typically referred to as non-admitted or unlicensed insurers. Non-admitted insurers are generally not licensed or authorized in the states in which they write business, although they must be licensed or authorized in the state in which they are domiciled. These companies have more flexibility and can react faster than standard line insurance companies because they are not required to file rates and forms. However, they still have substantial regulatory requirements placed upon them.
Most states require that excess line insurers submit financial information, articles of incorporation, a list of officers, and other general information. They also may not write insurance that is typically available in the admitted market, do not participate in state guarantee funds (and therefore policyholders do not have any recourse through these funds if an insurer becomes insolvent and cannot pay claims), may pay higher taxes, only may write coverage for a risk if it has been rejected by three different admitted insurers, and only when the insurance producer placing the business has a surplus lines license. Generally, when an excess line insurer writes a policy, it must, pursuant to state laws, provide disclosure to the policyholder that the policyholder's policy is being written by an excess line insurer.
On July 21, 2010, President Barack Obama signed into law the Nonadmitted and Reinsurance Reform Act of 2010 ("NRRA"), which took effect on July 21, 2011 and was part of the Dodd-Frank Wall Street Reform and Consumer Protection Act. The NRRA changed the regulatory paradigm for excess line insurance. Generally, under the NRRA, only the insured's home state may regulate and tax the excess line transaction.
Insurance companies are generally classified as either mutual or proprietary companies. Mutual companies are owned by the policyholders, while shareholders (who may or may not own policies) own proprietary insurance companies.
Demutualization of mutual insurers to form stock companies, as well as the formation of a hybrid known as a mutual holding company, became common in some countries, such as the United States, in the late 20th century. However, not all states permit mutual holding companies.
Other possible forms for an insurance company include reciprocals, in which policyholders reciprocate in sharing risks, and Lloyd's 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% 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 product 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.
The financial stability and strength of an insurance company should be a major consideration when buying 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 provide information and rate the financial viability of insurance companies.
Across the world 
Global insurance premiums grew by 2.7% in inflation-adjusted terms in 2010 to $4.3 trillion, climbing above pre-crisis levels. The return to growth and record premiums generated during the year followed two years of decline in real terms. Life insurance premiums increased by 3.2% in 2010 and non-life premiums by 2.1%. While industrialised countries saw an increase in premiums of around 1.4%, insurance markets in emerging economies saw rapid expansion with 11% growth in premium income. The global insurance industry was sufficiently capitalised to withstand the financial crisis of 2008 and 2009 and most insurance companies restored their capital to pre-crisis levels by the end of 2010. With the continuation of the gradual recovery of the global economy, it is likely the insurance industry will continue to see growth in premium income both in industrialised countries and emerging markets in 2011.
Advanced economies account for the bulk of global insurance. With premium income of $1,620bn, Europe was the most important region in 2010, followed by North America $1,409bn and Asia $1,161bn. Europe has however seen a decline in premium income during the year in contrast to the growth seen in North America and Asia. The top four countries generated more than a half of premiums. The US and Japan alone accounted for 40% of world insurance, much higher than their 7% share of the global population. Emerging economies accounted for over 85% of the world’s population but only around 15% of premiums. Their markets are however growing at a quicker pace.  The country expected to have the biggest impact on the insurance share distribution across the world is China. According to Sam Radwan of Enhance International, low premium penetration (insurance premium as a % of GDP), an ageing population and the largest car market in terms of new sales, premium growth has averaged 15–20% in the past five years, and China is expected to be the largest insurance market in the next decade or two.
Regulatory differences 
In the United States, insurance is regulated by the states under the McCarran-Ferguson Act, with "periodic proposals for federal intervention", and a nonprofit coalition of state insurance agencies called the National Association of Insurance Commissioners works to harmonize the country's different laws and regulations. The National Conference of Insurance Legislators (NCOIL) also works to harmonize the different state laws.
In the European Union, the Third Non-Life Directive and the Third Life Directive, both passed in 1992 and effective 1994, created a single insurance market in Europe and allowed insurance companies to offer insurance anywhere in the EU (subject to permission from authority in the head office) and allowed insurance consumers to purchase insurance from any insurer in the EU. As far as insurance in the United Kingdom, the Financial Services Authority took over insurance regulation from the General Insurance Standards Council in 2005; laws passed include the Insurance Companies Act 1973 and another in 1982, and reforms to warranty and other aspects under discussion as of 2012.
The insurance industry in China was nationalized in 1949 and thereafter offered by only a single state-owned company, the People's Insurance Company of China, which was eventually suspended as demand declined in a communist environment. In 1978, market reforms led to an increase in the market and by 1995 a comprehensive Insurance Law of the People's Republic of China was passed, followed in 1998 by the formation of China Insurance Regulatory Commission (CIRC), which has broad regulatory authority over the insurance market of China.
In India, IRDA is insurance regulatory authority. As per the section 4 of IRDA Act' 1999, Insurance Regulatory and Development Authority (IRDA), which was constituted by an act of parliament. National Insurance Academy, Pune is apex insurance capacity builder institute promoted with support from Ministry of Finance and by LIC, Life & General Insurance companies.
Insurance insulates too much 
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), a concept known 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 or at the direction of the insured. Even if a provider were so irrational as to want 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.
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.
For example, most insurance policies in the English language today have been carefully drafted in plain English; the industry learned the hard way that many courts will not enforce policies against insureds when the judges themselves cannot understand what the policies are saying. Typically, courts construe ambiguities in insurance policies against the insurance company and in favor of coverage under the policy.
Many institutional insurance purchasers buy insurance through an insurance broker. While on the surface it appears the broker represents the buyer (not the insurance company), and typically counsels the buyer on appropriate coverage and policy limitations, in the vast majority of cases a broker's compensation comes in the form of a commission as a percentage of the insurance premium, creating a conflict of interest in that the broker's financial interest is tilted towards encouraging an insured to purchase more insurance than might be necessary at a higher price. 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. A tied agent, working exclusively with one insurer, represents the insurance company from whom the policyholder buys (while a free agent sales policies of various insurance companies). Just as there is a potential conflict of interest with a broker, an agent has a different type of conflict. Because agents work directly for the insurance company, if there is a claim the agent may advise the client to the benefit of the insurance company. Agents generally cannot offer as broad a range of selection compared to an insurance broker.
An independent insurance consultant advises insureds on a fee-for-service retainer, similar to an attorney, and thus offers completely independent advice, free of the financial conflict of interest of brokers and/or agents. However, such a consultant must still work through brokers and/or agents in order to secure coverage for their clients.
Limited consumer benefits 
In United States, economists and consumer advocates generally consider insurance to be worthwhile for low-probability, catastrophic losses, but not for high-probability, small losses. Because of this, consumers are advised to select high deductibles and to not insure losses which would not cause a disruption in their life. However, consumers have shown a tendency to prefer low deductibles and to prefer to insure relatively high-probability, small losses over low-probability, perhaps due to not understanding or ignoring the low-probability risk. This is associated with reduced purchasing of insurance against low-probability losses, and may result in increased inefficiencies from moral hazard.
Redlining is the practice of denying insurance coverage in specific geographic areas, supposedly because of a high likelihood of loss, while the alleged motivation is unlawful discrimination. Racial profiling or redlining has a long history in the property insurance industry in the United States. From a review of industry underwriting and marketing materials, court documents, and research by government agencies, industry and community groups, and academics, it is clear that race has long affected and continues to affect the policies and practices of the insurance industry.
In July, 2007, The Federal Trade Commission (FTC) released a report presenting the results of a study concerning credit-based insurance scores in automobile insurance. The study found that these scores are effective predictors of risk. It also showed that African-Americans and Hispanics are substantially overrepresented in the lowest credit scores, and substantially underrepresented in the highest, while Caucasians and Asians are more evenly spread across the scores. The credit scores were also found to predict risk within each of the ethnic groups, leading the FTC to conclude that the scoring models are not solely proxies for redlining. The FTC indicated little data was available to evaluate benefit of insurance scores to consumers. The report was disputed by representatives of the Consumer Federation of America, the National Fair Housing Alliance, the National Consumer Law Center, and the Center for Economic Justice, for relying on data provided by the insurance industry. 
All states have provisions in their rate regulation laws or in their fair trade practice acts that prohibit unfair discrimination, often called redlining, in setting rates and making insurance available.
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., negative 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 goes to the heart of the risk a life insurer takes: Old people are likely to die sooner than young people, so the risk of loss (the insured's death) is greater in any given period of time and therefore the risk premium must be higher to cover the greater risk. However, treating insureds differently when there is no actuarially sound reason for doing so is unlawful discrimination.
What is often missing from the debate is that prohibiting the use of legitimate, actuarially sound factors means that an insufficient amount is being charged for a given risk, and there is thus a deficit in the system. The failure to address the deficit may mean insolvency and hardship for all of a company's insureds. The options for addressing the deficit seem to be the following: Charge the deficit to the other policyholders or charge it to the government (i.e., externalize outside of the company to society at large).
Insurance patents 
A recent example of a new insurance product that is patented is Usage Based auto insurance. Early versions were independently invented and patented by a major US auto insurance company, Progressive Auto Insurance (U.S. Patent 5,797,134) and a Spanish independent inventor, Salvador Minguijon Perez (EP 0700009 ).
Many independent inventors are in favor of patenting new insurance products since it gives them protection from big companies when they bring their new insurance products to market. Independent inventors account for 70% of the new US patent applications in this area.
Many insurance executives are opposed to patenting insurance products because it creates a new risk for them. The Hartford insurance company, for example, recently had to pay $80 million to an independent inventor, Bancorp Services, in order to settle a patent infringement and theft of trade secret lawsuit for a type of corporate owned life insurance product invented and patented by Bancorp.
There are currently about 150 new patent applications on insurance inventions filed per year in the United States. The rate at which patents have been issued has steadily risen from 15 in 2002 to 44 in 2006.
Inventors can now have their insurance US patent applications reviewed by the public in the Peer to Patent program. The first insurance patent application to be posted was US2009005522 “Risk assessment company”. It was posted on March 6, 2009. This patent application describes a method for increasing the ease of changing insurance companies.
The insurance industry and rent-seeking 
Certain insurance products and practices have been described as rent-seeking by critics. That is, some insurance products or practices are useful primarily because of legal benefits, such as reducing taxes, as opposed to providing protection against risks of adverse events. Under United States tax law, for example, most owners of variable annuities and variable life insurance can invest their premium payments in the stock market and defer or eliminate paying any taxes on their investments until withdrawals are made. Sometimes this tax deferral is the only reason people use these products. Another example is the legal infrastructure which allows life insurance to be held in an irrevocable trust which is used to pay an estate tax while the proceeds themselves are immune from the estate tax.
Religious concerns 
Muslim scholars have varying opinions about life insurance. Life insurance policies that earn interest (or guaranteed bonus/NAV) are generally considered to be a form of riba (usury) and some consider even policies that do not earn interest to be a form of gharar (speculation). Some argue that gharar is not present due to the actuarial science behind the underwriting.
Jewish rabbinical scholars also have expressed reservations regarding insurance as an avoidance of God's will but most find it acceptable in moderation.
Some Christians believe insurance represents a lack of faith[dead link] and there is a long history of resistance to commercial insurance in Anabaptist communities (Mennonites, Amish, Hutterites, Brethren in Christ) but many participate in community-based self-insurance programs that spread risk within their communities.
