问题如下：
Ace Bank enter into a credit default swap with City Bank that settles based on the performance of White company. If City Bank and White have the same initial credit rating and everything else remains the same, when City Bank buys White, the value of this credit default swap would:
选项：
A.
increases.
B.
remains the same.
C.
decreases.
D.
be unclear.
解释：
C is correct.
考点： CDS
解析：
If City Bank buys White, the two entities will default at the same time. This increase in the default correlation makes the CDS contract less valuable.
不太明白和CDS有啥关系？收购另一个公司跟CDS有什么关系呢？出题的点是啥，需要计算保费吗？
