英文名称：Act of God Bond 中文名称：天灾债券
保险公司发行的债券，旨在将债券的本金及利息与天然灾害造成的公司损失联系起来。

A bond issued by an insurance company, linking principal and interest to a company's losses due to natural disasters. Act of God bonds are issued by insurers to protect against unforeseen events. 

Such bonds create flexibility for insurance companies if an unforeseen natural disaster occurs. Because principal and interest depend directly on losses resulting from natural disasters, the insurance company can soften the financial strain by delaying, reducing or eliminating payment of the bond.
