If the person who purchased the bond fails at his or her task, the bonding company will pay the aggrieved party an amount up to the value of the bond. (2) An interest-bearing document issued by a government or company as evidence of a debt. A bond provides pre-determined payments at a set date to the bond holder. Bonds may be 'registered' bonds, which provide payment to the bond holder whose name is recorded with the issuer and appears on the bond certificate, or 'bearer' bonds, which provide payments to whomever holds the bond in-hand.

A seller's taking advantage of a buyer due to their unequal bargaining positions, perhaps because of the buyer's recent trauma, physical infirmity, ignorance, inability to read or inability to understand the language. The unfairness must be so severe that it is shocking to the average person. It usually includes the absence of any meaningful choice on the part of the buyer and contract terms so one-sided that they unreasonably favor the seller. A contract will be terminated if the buyer can prove unconscionability.
