Factors determining whether to insure events or not include;


1. There must be a larger number of similar objects so the financial outcome of insuring the pool of exposures is predictable. Therefore the insurer can calculate a "fair" premium.
2. The losses have to be accidental and unintentional (i.e., on the insured's part).
3. The losses must be measurable, identifiable in location and time, and definite. An insurer also requires that losses cause economic hardship. This so that the insured has an incentive to protect and preserve the property to minimize the probability that the losses occur.
4. The loss potential to the insurer must be non-catastrophic, i.e., it cannot put the insurance company in financial jeopardy.
Losses must be uncertain of occurrence.
