问题如下：
When market interest rate is 7%, a company issues a $1 million bond with maturity of 3-year, a 5% coupon rate, and annual interest payments.
Which of the following statements is the most correct?
选项：
A.The total interest expense reported by the issuer over the life of the bond will be $150,000.
B.The total interest expense reported by the issuer over the life of the bond will be $202,486.32.
C.The total interest expense reported by the issuer over the life of the bond will be $52,486.32.
解释：
B is correct.
Method 1:
The sum of Interest expenses=$66,325.96+$67,468.77+$68,691.59=$202,486.32
Method 2:
Coupon payments + discount interest = coupon payments + (face value - issue value)= $150,000 + ($1,000,000 - $947,513.68) = $202,486.32
.
老师，能不能解释一下答案解析中第二种方法是什么意思呢？不太懂为什么discount interest = par value - issue price
