Bonds are contracts fall into either Surety or Fidelity Bonds when talking about Property and Casualty insurance. From Wikipedia (https://en.wikipedia.org/wiki/Surety; accessed 05/09/2022):
Surety bond or guaranty involves a promise by one party to assume responsibility for the debt obligation of a borrower if that borrower defaults. Usually, a surety bond or surety is a promise by a surety or guarantor to pay one party (the obligee) a certain amount if a second party (the principal) fails to meet some obligation, such as fulfilling the terms of a contract. The surety bond protects the obligee against losses resulting from the principal's failure to meet the obligation. The person or company providing the promise is also known as a "surety" or as a "guarantor."
A fidelity bond is a form of insurance protection that covers policyholders for losses that they incur as a result of fraudulent acts by specified individuals. It usually insures a business for losses caused by the dishonest acts of its employees.
While called bonds, these obligations to protect an employer from employee-dishonesty losses are really insurance policies. These insurance policies protect from losses of company monies, securities, and other property from employees who have a manifest intent to i) cause the company to sustain a loss and ii) obtain an improper financial benefit, either for themselves or another party. There are also many other coverage extensions available through the purchase of additional insuring agreements. These are common to most crime insurance policies (burglary, fire, general theft, computer theft, disappearance, fraud, forgery, etc.) and are designed to further protect specific company assets.
