问题如下：

选项：
A.108 bps.
101 bps.
225 bps.
解释：
Correct Answer: A
The corporate bond’s fair value is computed in the solution to Question (3) as €1,101.24 The YTM can be obtained by solving the following equation for IRR:
The solution to this equation is 3.26%.
Valuation of a four-year, 6% coupon bond under no default (VND) is computed in the solution to Question (3) as 1,144.63. So, the YTM of a theoretical comparable-maturity government bond with the same coupon rate as the corporate bond B2 can be obtained by solving the following equation for IRR:
The solution to this equation is 2.18%. So, the credit spread that the analyst wants to compute is 3.26% – 2.18% = 1.08%, or 108 bps.
