问题如下:

The fair value of bond B2 is closest to:

选项:

A.

€1,069.34.

B.

€1,111.51.

C.

€1,153.68.

解释:

A is correct. The following table shows that the CVA for the bond is €42.17, the sum of the present values of expected loss. The steps taken to complete the table are as follows.

Step 1: Exposure at Date 4 is €1,000 + Coupon amount = €1,000 + €60 = €1,060. Exposure at a date T prior to that is Coupon on Date T + PV at Date T of subsequent coupons + PV of €1,000 to be received at Date 4.

For example, exposure at Date 2 is

60+ 60 (1+0.03) + 60 (1+0.03) 2 + 1000 (1+0.03) 2 =60+ 60 (1+0.03) + 1060 (1+0.03) 2 =1117.40

Steps 2 through 8 are the same as those in the solution to Question 1.

Value of the bond if the bond were default free would be €60 × DF1 + €60 × DF2 + €60 × DF3 + €1,060 × DF4 = €1,111.51.

Fair value of the bond considering CVA = €1,111.51 – €42.17 = €1,069.34

老师好:

正文里有两种yield curve,一是government bond yied curve flat at 3%,一是upward-sloping yield curve,这关乎到我们选哪个利率来算每一期的exposure,可是题目没说要用哪个yield curve。哪里显示我们得用flat yield curve 3%来算呢? 谢谢!

老师好: 我再次把正文看了一遍,已经找到线索了 "Answer the first five questions (1-4) based on the assumptions made by Marten Koning, the junior analyst",所以您可以忽略我这个提问,谢谢!
