Insurance is a cover used for protecting a person from the financial losses. Financial losses can take many forms. There are risks to our investments, liabilities for our actions, and risks to our ability to earn income.
The insurer and the insured are the main two parties involved in insurance. The insurer is the insurance company which will provide the cover to the insured against any financial losses. The insured may be an individual person or a group of people like an employee, members of a society, etc.
Basic categorization of Insurance
There are mainly two broad categories of insurance
- Life insurance
- Non-life insurance
Life insurance products include life term policies, which give clean risk coverage of only the death benefit, whereas endowment or money back policies have a risk as well as savings component ie death as well as maturity benefit. The life insurance also includes Unit – Linked Policies in which there is a risk component and a savings component, which is invested in equity, debt or gilt funds, depending on the insurance company.
Non Life insurance products include property or casualty, health insurance or house, fire, marine insurance etc. This insurance category deals with all the non-life aspects of an insured like their house, health, land, office, etc which may bring financial loss.
There are few principals of insurance, such as:
- Definite Loss – Insurance – 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.
- Unintentional or Accidental Loss – Insurance – The event that participates the trigger of a claim should be arbitrary, 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.
- Huge Loss – Insurance – 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 rationally assure that the insurer will be able to pay claims.
- Affordable Premium – Insurance – If the probability of an insured event is so high, or the cost of the event is 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.
- A large number of identical coverage units – Insurance – The vast majority of insurance policies are provided for individual members of very large classes. The existence of a large number of identical coverage units allows insurers to benefit from the so-called "law of large numbers," which in effect states that as the number of coverage units increases, the actual results are increasing significantly to close close to expected results.
- Measurable Loss – Insurance – There are two elements that must be at least estimatable, if not typically 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 assessment of the amount of the loss recoverable as a result of the claim.
- Limited risk of substantially large losses – Insurance – 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.
