题目
In a securitization, time tranching provides investors with the ability to choose between:
选项
A.extension and contraction risks.
B.senior and subordinated bond classes.
C.fully amortizing and partially amortizing loans.
答案
A
解析
： A is correct. Time tranching is the process in which a set of bond classes or tranches is created that allow investors a choice in the type of prepayment risk, extension or contraction, that they prefer to bear. Senior and subordinated bond classes are used in credit tranching. Credit tranching structures allow investors to choose the amount of credit risk that they prefer to bear. Fully and partially amortizing loans are two types of amortizing loans. ： A是正确的。时间分层是指建立一系列债券类别或层级的过程，允许投资者选择他们愿意承担的提前还款风险、延期或收缩的类型。高级和次级债券类别属于信用分层。信用分层结构允许投资者选择他们愿意承担的信用风险的数额。全部和部分摊销贷款是两种类型的摊销贷款。
