There are certain principles of insurance which could be followed

A large number of homogenous units: A large number of insurance policies are provided for individual members. Insurance given against a vehicle to millions or some other insurances the existence of a large number of people allows the insuring giving companies to benefit from "law of large numbers" which is described as a result that is performed by repeating the same experiment continuously. The law of large numbers has affected a large number of states which has increased a large number of exposure units. Whereas the actual results are increasing that are likely to become to the expected proportions.

Lloyd’s of London is famous for giving insurance for the health or life of the actors, underwriters, sports personality and many more. Larger commercial properties have certain polices that may insure exceptional properties which has no homogenous exposure units. Many homogenous exposure units are considered to be insurable.

Calculable Loss: This category consists of two elements one is known as attendant cost and the other is the probability of loss. Probability of loss is driven from experiment and observation of a person’s loss while the attendant cost has more to do with a person who holds his chattels and a copy of insurance policy and claims a property under the policy which retains an object or the amount of loss recoverable as a result of the claim.

Affordable Premium: Insurance will not be sold if it is too high, which results to a premium which is large compared to the amount that is offered against protection or the cost of the event is too high. Moreover the premium should not be so high that it would affect a loss to the insurer. If there are no chances of loss then the transaction would be in form of insurance.

Large Loss: This depends on the size of a loss. Insurance premiums have to cover both cost of issuing and the expected cost of losses and also adjusting the losses as well as the administrative policy. The insurance premiums supplies the capital that is needed by assure that is given by the insurer who will be able to pay the claims.

Accidental Loss: Insurance will be given to a person during an accident when the person proves it to be real. In this case if there is a loss in the in an ordinary business then the owner is not liable to be paid the insurance.

Definite Loss: In case of a sudden demise of a person, the members are liable to get the insurance. The other factors that meet these criteria are in case of an accident or workers who are injured at the work places. Similarly, if one has to claim insurance then he has to prove the insurance company about the loss n which the time, place and the loss of the person are taken under consideration. Whereas in case of an occupational disease a person cannot claim for insurance benefits, the reason behind this is occupational disease may involve prolong time, place or cause which is identifiable.
