Compared with the weighted average coupon rate of its underlying pool of mortgages, the pass-through rate on a mortgage pass-through security is:
A. lower.
B. the same.
C. higher.
解析:选A。抵押贷款传递证券的息票率称为传递利率,而基础抵押贷款池的抵押贷款利率是加权平均息票率(WAC)计算。传递率低于WAC,其金额等于服务费和其他行政费用。
Q13-1 [Attention] Which commercial mortgage-backed security (CMBS) characteristic causes a CMBS to trade more like a corporate bond than a residential mortgage-backed security (RMBS)?
A. Call protection
B. Internal credit enhancement
C. Debt-service coverage ratio level
解析:选A。对于CMBS,投资者有相当大的赎回保护(call protection)。投资于RMBS的投资者面临着相当大的提前支付风险,但对于CMBS,投资者可以在结构和贷款层面上获得赎回保护。赎回保护导致CMBS在市场上的交易更像是公司债券,而不是RMBS。其他选项,内部信用增级和DSC比率处理的都是信用风险,而不是提前还款风险。
