老师求解~~

NO.PZ2017012501000009

问题如下:

The longest-term tranche of a sequential-pay CMO is most likely to have the lowest:

选项:

A.

average life.

B.

extension risk.

C.

contraction risk.

解释:

C is correct.

For a CMO with multiple sequential-pay tranches, the longest-term tranche will have the lowest contraction (prepayments greater than forecasted) risk because of the protection against this risk offered by the other tranches. The longest-term tranche is likely to have the highest average life and extension risk because it is the last tranche repaid in a sequential-pay tranche.

考点:CMO

解析:longest term tranche是最后还款的那一层,该层的延期风险最大,缩期风险最小,故选项C正确。

老师这题错了五次!!除了support,其他都是先还上层吗?傻傻分不清,能不能帮忙捋一下~~

嗨,从没放弃的小努力你好:


1、CMO中有两个结构,一个是sequential-pay,第二个是PAC、support结构。support结构是PAC的保镖,support层次承担了所有的风险。除这个结构以外,其他都是按照优先级依次往下还款。

2、这道题考的是sequential-pay,也就是按顺序支付。从上到下的层次依次还款。longest-term tranche,层级的存续期最长,也就意味着是最后还款的那一层,所以是延期风险最大。选C。
