请问可以解释一下A和B吗～谢谢

问题如下：

A bond that is characterized by a fixed periodic payment schedule that reduces the bond’s outstanding principal amount to zero by the maturity date is best described as a:

选项：

A.

bullet bond.

B.

plain vanilla bond.

C.

fully amortized bond.

解释：

C is correct.

A fully amortized bond calls for equal cash payments by the bond’s issuer prior to maturity. Each fixed payment includes both an interest payment component and a principal repayment component such that the bond’s outstanding principal amount is reduced to zero by the maturity date.

A and B are incorrect because a bullet bond or plain vanilla bond only make interest payments prior to maturity. The entire principal repayment occurs at maturity.

考点：cash flow structure

解析：全额摊销债券要求发行人在到期前支付等额现金。每次固定支付包括利息支付部分和本金偿还部分，这样债券的未偿还本金金额在到期日减为零。故选项C正确。
