Insurance is a means of protection from financial loss. It is a form of risk management, primarily used to hedge against the risk of a contingent or uncertain loss. An entity which provides insurance is known as an insurer, an insurance company, an insurance carrier or an underwriter. A person or entity who buys insurance is known as an insured or as a policyholder. The insurance transaction involves the insured assuming a guaranteed and known - relatively small - loss in the form of payment to the insurer in exchange for the insurer's promise to compensate the insured in the event of a covered loss.
