Insurance provides financial protection against a loss arising out of happening of an uncertain event. A person can avail this protection by paying premium to an insurance company.

A pool is created through contributions made by persons seeking to protect themselves from common risk. Premium is collected by insurance companies which also act as trustee to the pool. Any loss to the insured in case of happening of an uncertain event is paid out of this pool.

Insurance works on the basic principle of risk-sharing. A great advantage of insurance is that it spreads the risk of a few people over a large group of people exposed to risk of similar type.
