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. An insurer is a company selling the insurance. The insurance rate is a factor used to determine the amount, called the premium, to be charged for a certain amount of insurance coverage. Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study and practice.
Principles of insurance
A large number of homogeneous exposure units. The vast majority of insurance policies are provided for indivial members of very large classes. Automobile insurance, for example, covered about 175 million automobiles in the United States in 2004.[2] The existence of a large number of homogeneous exposure units allows insurers to benefit from the so-called “law of large numbers,” which in effect states that as the number of exposure units increases, the actual results are increasingly likely to become close to expected results. There are exceptions to this criterion. Lloyd's of London is famous for insuring the life or health of actors, actresses and sports figures. Satellite Launch insurance covers events that are infrequent. Large commercial property policies may insure exceptional properties for which there are no ‘homogeneous’ exposure units. Despite failing on this criterion, many exposures like these are generally considered to be insurable.
Definite Loss. The event that gives rise to the loss that is subject to insurance should, at least in principle, take place at a known time, in a known place, and from a known cause. The classic example is death of an insured on a life insurance policy. Fire, automobile accidents, and worker injuries may all easily meet this criterion. Other types of losses may only be definite in theory. Occupational disease, for instance, may involve prolonged exposure to injurious conditions where no specific time, place or cause is identifiable. Ideally, the time, place and cause of a loss should be clear enough that a reasonable person, with sufficient information, could objectively verify all three elements.
Accidental Loss. The event that constitutes the trigger of a claim should be fortuitous, or at least outside the control of the beneficiary of the insurance. The loss should be ‘pure,’ in the sense that it results from an event for which there is only the opportunity for cost. Events that contain speculative elements, such as ordinary business risks, are generally not considered insurable.
Large Loss. The size of the loss must be meaningful from the perspective of the insured. Insurance premiums need to cover both the expected cost of losses, plus the cost of issuing and administering the policy, adjusting losses, and supplying the capital needed to reasonably assure that the insurer will be able to pay claims. For small losses these latter costs may be several times the size of the expected cost of losses. There is little point in paying such costs unless the protection offered has real value to a buyer.
Affordable Premium. If the likelihood of an insured event is so high, or the cost of the event so large, that the resulting premium is large relative to the amount of protection offered, it is not likely that anyone will buy insurance, even if on offer. Further, as the accounting profession formally recognizes in financial accounting standards, the premium cannot be so large that there is not a reasonable chance of a significant loss to the insurer. If there is no such chance of loss, the transaction may have the form of insurance, but not the substance. (See the U.S. Financial Accounting Standards Board standard number 113)
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. 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 indivial 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 indivial policy could proce 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 instry, 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 indivial 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.
[edit] Indemnification
Main article: Indemnity
The technical definition of "indemnity" means to make whole again. There are two types of insurance contracts; 1) an "indemnity" policy and 2) a "pay on behalf" or "on behalf of"[3] policy. The difference is significant on paper, but rarely material in practice.
An "indemnity" policy will never pay claims until the insured has paid out of pocket to some third party; i.e. a visitor to your home slips on a floor that you left wet and sues you for $10,000 and wins. Under an "indemnity" policy the homeowner would have to come up with the $10,000 to pay for the visitors fall and then would be "indemnified" by the insurance carrier for the out of pocket costs (the $10,000)[4].
Under the same situation, a "pay on behalf" policy, the insurance carrier would pay the claim and the insured (the homeowner) would not be out of pocket for anything. Most modern liability insurance is written on the basis of "pay on behalf" language[5].
An entity seeking to transfer risk (an indivial, 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.
[edit] Insurer’s business model
Profit = earned premium + investment income - incurred loss - underwriting expenses.
Insurers make money in two ways: (1) through underwriting, the process by which insurers select the risks to insure and decide how much in premiums to charge for accepting those risks and (2) 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 procts 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 underwriting profitability, while anything over 100 indicates an underwriting 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 instry 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. [6]
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, e 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, fraulent insurance practices are a major business risk that must be managed and overcome.
Types of insurance
Any risk that can be quantified can potentially be insured. Specific kinds of risk that may give rise to claims are known as "perils". An insurance policy will set out in detail which perils are covered by the policy and which are not. Below are (non-exhaustive) lists of the many different types of insurance that exist. A single policy may cover risks in one or more of the categories set forth below. For example, auto insurance would typically cover both property risk (covering the risk of theft or damage to the car) and liability risk (covering legal claims from causing an accident). A homeowner's insurance policy in the U.S. typically includes property insurance covering damage to the home and the owner's belongings, liability insurance covering certain legal claims against the owner, and even a small amount of health insurance for medical expenses of guests who are injured on the owner's property.
Business insurance can be any kind of insurance that protects businesses against risks. Some principal subtypes of business insurance are (a) the various kinds of professional liability insurance, also called professional indemnity insurance, which are discussed below under that name; and (b) the business owners policy (BOP), which bundles into one policy many of the kinds of coverage that a business owner needs, in a way analogous to how homeowners insurance bundles the coverages that a homeowner needs.[7]
Health
Health insurance policies will often cover the cost of private medical treatments if the National Health Service in the United Kingdom (NHS) or other publicly-funded health programs do not pay for them. It will often result in quicker health care where better facilities are available. Dental insurance, like medical insurance, is coverage for indivials to protect them against dental costs. In the U.S., dental insurance is often part of an employer's benefits package, along with health insurance. Most countries rely on public funding to ensure that all citizens have universal access to health care.
[edit] Disability
Disability insurance policies provide financial support in the event the policyholder is unable to work because of disabling illness or injury. It provides monthly support to help pay such obligations as mortgages and credit cards.
Total permanent disability insurance insurance provides benefits when a person is permanently disabled and can no longer work in their profession, often taken as an adjunct to life insurance.
Disability overhead insurance allows business owners to cover the overhead expenses of their business while they are unable to work.
Workers' compensation insurance replaces all or part of a worker's wages lost and accompanying medical expense incurred because of a job-related injury.
Casualty
Casualty insurance insures against accidents, not necessarily tied to any specific property.
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 will result in a loss.
[edit] Life insurance
Main article: Life insurance
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.
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 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.
Property
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.

there are a few principles of insurance, which are considered as the uncertain losses, the predictable rate and distribution of losses,the sinificant of loss and the loss must be catastrophic.
A property or liability insurance policy is a "personal contract," a "conditional contract," a "unilateral contract," a "contract of adhesion," a "contract of indemnity," and a contract which requires that the person insured have an insurable interest at the time of the insured-against contingency.
Further: An Insurance Contract is one of Uberrima fides. This is a Latin phrase meaning "utmost good faith" (or translated literally, "most abundant faith"). It is the name of a legal doctrine which governs insurance contracts. This means that all parties to an insurance contract must deal in good faith, making a full declaration of all material facts in the insurance proposal. This contrasts with the legal doctrine of caveat emptor (let the buyer beware).
An entity seeking to transfer risk (an indivial, corporation, or association of any type) becomes the 'insured' party once risk is assumed by an 'insurer', the insuring party, by means of a contract, defined as an insurance 'policy'. This legal contract sets out terms and conditions specifying the amount of coverage (compensation) to be rendered to the insured, by the insurer upon assumption of risk, in the event of a loss, and all the specific perils covered against (indemnified), for the term of the contract.
When insured parties experience a loss for a specified peril, the coverage entitles the policyholder to make a 'claim' against the insurer for the amount of loss as specified by the policy contract. The fee paid by the insured to the insurer for assuming the risk is called the 'premium'. Insurance premiums from many clients are used to fund accounts set aside 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, the remaining margin becomes their profit.
Insurers make money in two ways. Through underwriting, the process through which insurers select what risks to insure and decide how much premium to charge for accepting those risks and by investing the premiums they have collected from insureds
Some people consider insurance a type of wager (particularly as associated with moral hazard) that executes over the policy period. The insurance company bets that you or your property will not suffer a loss while you put money on the opposite outcome. The difference in the fees paid to the insurance company versus the amount for which they can be held liable if an accident happens is roughly analogous to the odds one might expect when betting on a racehorse (for example, 10 to 1). For this reason, a number of religious groups, including the Amish and some Muslim groups, avoid insurance and instead depend on support provided by their communities when disasters strike. This can be thought of as "social insurance," as the risk of any given person is assumed collectively by the community who will all bear the cost of rebuilding. In closed, supportive communities where others can be trusted to step in to rebuild lost property, this arrangement can work.
Any risk that can be quantified probably has a type of insurance to protect it. Among the different types of insurance are:
Automobile insurance, also known as auto insurance, car insurance and 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 vehicle itself. Over most of the United States purchasing an auto insurance policy is required to legally operate a motor vehicle on public roads. Recommendations for which policy limits should be used are specified in a number of books. In some jurisdictions, bodily injury compensation for automobile accident victims has been changed to No Fault systems, which rece or eliminate the ability to sue for compensation but provide automatic eligibility for benefits.
Boiler insurance (also known as Boiler and Machinery insurance or Equipment Breakdown Insurance)
Casualty insurance insures against accidents, not necessarily tied to any specific property.
Credit insurance pays some or all of a loan back when certain things happen to the borrower such as unemployment, disability, or death.
Financial loss insurance protects indivials 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 failure of a creditor to pay money it owes to the insured. Fidelity bonds and surety bonds are included in this category.
Health insurance covers medical bills incurred because of sickness or accidents.
Liability insurance covers legal claims against the insured. For example, a homeowner's insurance policy provides the insured with protection in the event of a claim brought by someone who slips and falls on the property, and brings a lawsuit for her injuries. Similarly, a doctor may purchase liability insurance to cover any legal claims against him if his negligence (carelessness) in treating a patient caused the patient injury and/or monetary harm. The protection offered by a liability insurance policy is two-fold: a legal defense in the event of a lawsuit commenced against the policyholder, plus indemnification (payment on behalf of the insured) with respect to a settlement or court verdict.
Life insurance provides a cash benefit to a decedent's family or other designated beneficiary, and may specifically provide for burial, funeral and other final expenses.
Annuities provide a stream of payments and are generally classified as insurance because they are issued by insurance companies and regulated as insurance. 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.
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.
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 unauthorised parties. In special cases, a government may authorise its use in protecting semi-private funds which are liable to tamper. Terms of this type of insurance are usually very strict. As such it is only used in extreme cases where maximum security of funds is required.
Marine Insurance covers the loss or damage of goods at sea. Marine insurance typically compensates the owner of merchandise for losses sustained from fire, shipwreck, etc., but excludes losses that can be recovered from the carrier.
Nuclear incident insurance — damages resulting from an incident involving radioactivive materials is generally arranged at the national level. (For the United States, see Price-Anderson Nuclear Instries Indemnity Act.)
Environmental Liability Insurance protects the insured from bodily injury, property damage and cleanup costs as a result of the dispersal, release or escape of a pollutant.
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.
Professional Indemnity Insurance is normally a mandatory requirement for professional practitioners such as Architects, Lawyers, Doctors and Accountants to provide insurance cover against potential negligence claims. Non licensed professionals may also purchase malpractice insurance, it is commonly called Errors and Omissions Insurance and covers a service provider for claims made against them that arise out of the performance of specified professional services. For instance, a web site designer can obtain E&O insurance to cover them for certain claims made by third parties that arise out of negligent performance of web site development services.
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.
Terrorism insurance
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 done 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, lost of personal belongings, travel delay, personal liabilities.. etc.
Workers' compensation insurance replaces all or part of a worker's wages lost and accompanying medical expense incurred e to a job-related injury.
A single policy may cover risks in one or more of the above categories. For example, car insurance would typically cover both property risk (covering the risk of theft or damage to the car) and liability risk (covering legal claims from say, causing an accident). A homeowner's insurance policy in the U.S. typically includes property insurance covering damage to the home and the owner's belongings, liability insurance covering certain legal claims against the owner, and even a small amount of health insurance for medical expenses of guests who are injured on the owner's property.
Potential sources of risk that may give rise to claims are known as "perils". Examples of perils might be fire, theft, earthquake, hurricane and many other potential risks. An insurance policy will set out in details which perils are covered by the policy and which are not.
Insurance companies may be classified as
Life insurance companies, who sell life insurance, annuities and pensions procts.
Non-life or general insurance companies, who sell other types of insurance.
In most countries, life and non-life insurers are subject to different regulations, tax and accounting rules. The main reason for the distinction between the two types of company is that life 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.
