Principles of insurance

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

DEBIT CARD

A debit card (also known as a bank card or check card) is a plastic card that provides an alternative payment method to cash when making purchases. Functionally, it can be called an electronic cheque, as the funds are withdrawn directly from either the bank account, or from the remaining balance on the card. In some cases, the cards are designed exclusively for use on the Internet, and so there is no physical card.
The use of debit cards has become widespread in many countries and has overtaken the cheque, and in some instances cash transactions by volume. Like credit cards, debit cards are used widely for telephone and Internet purchases, and unlike credit cards the funds are transferred from the bearer's bank account instead of having the bearer to pay back on a later date.
Debit cards can also allow for instant withdrawal of cash, acting as the ATM card for withdrawing cash and as a cheque guarantee card. Merchants can also offer "cashback"/"cashout" facilities to customers, where a customer can withdraw cash along with their purchase.
orn-again Democrats recently made a big to-do in reining in credit card industry abuses. To really safeguard our interests, the new U.S. Consumer Financial Protection Agency now needs to halt the banking industry's coup in progress and the means of its power grab: the debit card.
Being able to whip out a debit card for virtually any transaction is so convenient. Yet in promoting our evolution to a cashless society, banks have commandeered and privatized the nation's payment system, and they profit mightily on all types of purchases, down to buying a candy bar.
The industry's initial aim was to reduce cash-handling, check-clearing and accounting costs via electronic transactions, including direct deposit of paychecks and automatic withdrawals for bills and expenses.
Its ultimate windfall: While reaping those savings, it now generates billions in fee-based income -- and we've all sacrificed financial privacy in ways we've not yet even begun to fathom.
Used to be debit card purchases wouldn't go through without sufficient funds in a cardholder's account. Then opportunistic banks realized that, with direct deposit, they could recoup the overdrawn funds the instant their clients' next payroll checks rolled in.
Credit card holders aren't on the hook for fraudulent use of their card numbers and can challenge charges on goods and services not delivered as promised. Debit card holders aren't guaranteed those same protections.
The reason: It's the lenders' money on the line with a credit card transaction -- and just our hard-earned savings with debit card fraud. They'll absorb the cost of investigating and prosecuting theft of their money, but they don't want to pick up the cost of policing the theft of ours -- by identical means through their very same hands.
Credit card borrowers are never out more than $50 regardless of when they discover potential fraud. Debit card holders' liability is limited to $50 only if they report perceived fraud within two days; the liability jumps to a maximum $500 from that point to 60 days and is unlimited thereafter.
When consumers buy gift cards, they essentially give retailers an interest-free loan until the recipient uses the card, rather generous when you think about it. Yet on many cards, in small print, is the caveat that the card's value is wiped out if not used by a certain date.
