问题如下：
A company issues €10,000,000 face value of 10-year bonds dated 1 January 2015 when the market interest rate on bonds of comparable risk and terms is 6%. The bonds pay 7% interest annually on 31 December. Based on the effective interest rate method, the interest expense on 31 December 2015 is closest to:
选项：
A.€644,161.
B.€700,000.
C.€751,521.
解释：
A is correct.
N=10, I/Y=6, FV=10,000,000, PMT=700,000, → PV= €10,736,008.71
The interest expense is calculated by multiplying the carrying amount at the beginning of the year by the effective interest rate at issuance. As a result, the interest expense at 31 December 2015 is €644,161 (€10,736,008.71 × 6%).
这道题的coupon就是%7，利率就是%6～一般怎么分辨利率就看市场利率就是利率，是么？？？？
