Losses must be uncertain.
The rate of losses must be relatively predictable: In order to set premiums (prices) insurers must be able to estimate them accurately. This is done using the Law of Large Numbers which states that: The larger the number of homogenous exposures considered, the more closely the losses reported will equal the underlying probability of loss. If the coverage is unique, the insured will pay a correspondingly higher premium. Lloyd's of London often accepts unique coverages. (e.g., the insuring of Tina Turner's legs and Jennifer Lopez's buttocks)
The loss must be significant: The legal principle of De minimis dictates that trivial matters are not covered. Furthermore, rational insurance uses existing insurance when the transaction costs dictate that filing a claim is not rational.
The loss must not be catastrophic: If the insurer is insolvent, it will be unable to pay the insured. In the United States, there is a system of Guaranty Funds run at the state level to reimburse insured people whose insurance companies have become insolvent. [1] This program is run by the National Association of Insurance Commissioners (NAIC). [2] To avoid catastrophic depletion of their own capital, insurers almost universally purchase reinsurance to protect them against excessively large accumulations of risk in a single area, and to protect them against large-scale catastrophes.
Additionally, “speculative risks” like those incurred through gambling or through the purchase of company stocks are uninsurable.
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 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).
Property and liability insurance policies cover persons and not property or operations. Although the terms "insured my house" or "insured my motorcycle" are used commonly, they are not technically correct. The contract between the insurer and the insured is a personal contract between an insuring entity and a person(s) based upon their financial, "insurable interest", in the object or liability being insured. In other words, the question of whether payment is due upon the occurrence of a contingency, and how such payment will be measured, depends upon economic loss suffered by the person(s).
Property and liability insurance policies are said to be "conditional contracts" because the obligation of the insurer to perform may be conditioned upon the insured satisfying certain conditions.
Only one party is legally bound to contractual obligations after the premium is paid to the insurer. Only the insurer has made a promise of future performance, and only the insurer can be charged with breach of contract.
Property and liability insurance policies are said to be "contracts of adhesion" because the insurer and insured parties are of unequal bargaining power where the insured party cannot negotiate the terms of the contract and must take the offer of the insurer as made. Importantly, the rule of law regarding "contracts of adhesion" is that any ambiguities resolve in favor of the insured.
Property and liability insurance policies are said to be "contracts of indemnity" because the purpose of insurance is to indemnify the insured—that is, to make good a loss that the insured has suffered. The principle of indemnification is that the insured should not profit from the policy. This does not preclude that the insured will suffer some loss. In fact, many policies include a deductible which guarantees that the insured will pay part of each loss himself.
Insurable interest is one wherein economic loss would be suffered from an adverse occurrence to the person(s) insured.
A contract of insurance is valid in law only if the insured has an insurable interest—that is, if he has a legally recognized financial relationship with the subject matter of the insurance and stands to lose out if that subject is damaged.
An entity seeking to transfer risk (an individual, 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.
Profit = Earned Premium + Investment Income - Incurred Loss - Underwriting Expenses.
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.
The most difficult aspect of the insurance business is the underwriting of polices. Based on a wide assortment of data, insurers predict the likelihood that a claim will be made against their polices and price products accordingly. At the end of the policy term, the amount of premium collected minus the amount paid out in claims is the insurer's underwriting profit.
An insurer's underwriting performance is measured in their combined ratio. The loss ratio (incurred losses and loss-adjustment expenses divided by net earned premium) is added to the expense ratio (underwriting expenses divided by net premium written) to determine the company's combined ratio. The combined ratio is a reflection of the company's overall underwriting profitability. A combined ratio of less than 100 percent indicates profitability, while anything over 100 indicates a loss.
One company that is famous for achieving underwriting profit is American International Group.
Berkshire Hathaway, by contrast, is famous for making its money on "float" rather than underwriting profit. “Float” describes a process by which insurers invest insurance premiums as soon as they are collected and make interest on these monies before claims must be paid out.
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.
Insurers currently make the most money from their auto insurance line of business. Generally better statistics are available on auto losses and underwriting on this line of business has benefited greatly from advances in computing. Additionally, property losses in the US, due to natural catastrophes, have perpetuated this trend.
The insurer uses actuarial science to quantify the risk they are willing to assume. Data is generated to approximate future claims, ordinarily with reasonable accuracy. Actuarial science uses statistics and probability to analyze the risks associated with the range of perils covered, and these scientific principles are used by insurers, in conjunction with additional factors, to determine rate structures.
For example, many individuals purchase homeowner's insurance policies by signing a contract paying a premium to an insurance company. If a covered loss occurs, the insurer is obliged by the terms of the contract to honor the insured's claim. For some policyholders, the amount of insurance benefits received from their insurer will greatly exceed the expense of premiums paid. Others may never make a claim or receive any benefit other than the peace of mind rendered by the security of an insurance policy. When averaged, the total claims expense paid by an insurer should be less than the total premiums paid by their policyholders, with the difference allocated to overhead and profit.
Insurance companies also earn investment profits. These are generated by investing premiums received until they are needed to pay claims. This money is called the 'float'. The insurer may make profits or losses from the value change in the float as well as interest or dividends on the float. 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, at 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.
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, 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., interest income of life insurance policy (or annuity) is income tax deferred in general. However, its tax deferred benefit may be offset by a low return in some cases. This depends upon the insuring company, type of policy and other variables (mortality, market return, etc.). In 2000 and 2001 permanent life insurance had the second greatest investment return besides real estate. Also, other income tax saving vehicles (i.e. IRA, 401K or Roth IRA) appear to be better alternatives for value accumulation. Combination of low-cost term life insurance and higher return tax-efficient retirement account can achieve better performance.
Global insurance premiums grew by 9.7% in 2004 to reach $3.3 trillion. This follows 11.7% growth in the previous year. Life insurance premiums grew by 9.8% during the year due to rising demand for annuity and pension products. Non-life insurance premiums grew by 9.4% as premium rates increased. Over the past decade, global insurance premiums rose by more than a half as annual growth fluctuated between 2% and 10%.
Advanced economies account for the bulk of global insurance. With premium income of $1,217bn in 2004, North America was the most important region, followed by the EU ($1,198bn) and Japan ($492bn). The top four countries accounted for nearly two-thirds of premiums in 2004. The United States and Japan alone accounted for a half of world insurance, much higher than their 7% share of the global population. Emerging markets accounted for over 85% of the world’s population but generated only 10% of premiums. The volume of UK insurance business totalled $295bn in 2004 or 9.1% of global premiums. [3]
Financial stability and strength of the insurance company should be a major consideration when purchasing an insurance contract. An insurance premium paid currently provides coverage for losses that might arise many years in the future. For that reason, the viability of the insurance carrier is very important. In recent years, a number of insurance companies have become insolvent, leaving their policyholders with no coverage (or coverage only from a government-backed insurance pool with less attractive payouts for losses). A number of independent rating agencies, such as Best's, provide information and rate the financial viability of insurance companies.
