Hsu also selects the two floating-rate bonds issued by Varlep, plc given in the table below. These bonds have a maturity of three years and the same credit rating.
To value Varlep’s bonds, Hsu constructs the binomial interest rate tree provided in the exhibit below:
The value of Bond #7 is to:
选项：
A.99.697% of par.
B.99.936% of par.
C.101.153% of par.
解释：
A is correct.
考点：利用二叉树模型对浮动利率债券进行估值
解析：

year3 这列的三个数字是怎么算出来的？
