03.单选题 已收藏 标记 纠错 In the context of commercial mortgage-backed securities (CMBS) which of the following mechanisms is most likely a structural call protection? A Prepayment lockouts. B Yield maintenance charges. C Sequential-pay tranches. 查看解析 上一题 下一题 正确答案C 您的答案C本题平均正确率：56% CMBS难度：一般 推荐：      答案解析 C is correct. A structural call protection can be achieved in a CMBS when it is structured to have sequential-pay tranches by credit rating. A is incorrect because prepayment lockouts are a call protection mechanism offered to investors at the loan level. B is incorrect because yield maintenance charges are a call protection mechanism offered to investors at the loan level. 问：问题和本题可能没太大关联，maintain yield说的是折现，但是具体什么意思 怎么操作没有理解，可否简单解释一下？还有它贴现 是以哪个r贴现，怎么就能使投资人还是银行不损失？
