In a surety bond, which party guarantees that the obligation will be carried out?

解析

Suretyship is a three-party guarantee. The principal owes the duty and must perform, the obligee is the party protected and the one who required the bond, and the surety guarantees the principal's performance and may seek reimbursement from the principal after paying a claim. That right of reimbursement is what separates a surety bond from insurance. A fidelity bond is a different animal: it protects an employer against loss from its own employees' dishonesty and works as insurance rather than as a guarantee of somebody else's promise.
