嗨,从没放弃的小努力你好:


这里考察的是CDS保费的计算。


表格里的数据:bid是指MAC保险公司愿意买入CDS的价格,也就是Vision Hedge Fund卖CDS给MAC的价格。而ask是指的Vision Hedge Fund从MAC手里买入CDS的价格。


所以premium payment就等于Vision Hedge Fund支付的CDS买价,200 million的面值乘以116的ask price减去Vision Hedge Fund卖出的两份CDS的保费,分别是300*28和100*75,这里28和75要用bid price。最终结果是0.73million,选A
