表格数据没理解

问题如下：

A commercial paper has the following characteristics:

For a 365-day year, the discount rate is closest to:

选项：

A.6.2%. B.6.4%. C.6.6%.

解释：

B is correct.

DR = (Year/Days) × ((FV – PV)/FV), where Year = number of days in the year, Days = number of days between settlement and maturity, FV = future value paid at maturity/face value of the money market instrument, PV = present value/price of the money market instrument, and FV – PV, is the interest earned.

DR = (365/160) × (140,500/5,000,000) = 0.0641 ≈ 6.4%.

考点：Discount Rate

解析：Discount Rate是折价率，是在面值的基础上进行折价，相当于在面值100的基础上打一个折扣。表格中的Redemption value代表的是面值FV，Interest earned = FV-PV

DR= Year/Day×[(FV-PV)/FV]= (365/160) × (140,500/5,000,000) = 0.0641 ≈ 6.4%
