由于后面视频部分没有，麻烦老师解释一下，对interest coverage ratio如何影响的呢？从EBIT/I 和EBT/I这两个方面影响，感谢。

你好老师第七题为什么不选A

05.单选题 收藏 标记 纠错 To obtain the spot yield curve, a bond analyst would most likely use the most: A recently issued and actively traded corporate bonds. B recently issued and actively traded government bonds. C seasoned and actively traded government bonds. 查看解析 上一题 提交试卷 正确答案B 您的答案A本题平均正确率：84% Yield curve难度：一般 推荐：      答案解析 B is correct. To obtain the spot yield curve, a bond analyst would prefer to use the most recently issued and actively traded government bonds. Such bonds will have similar liquidity as well as fewer tax effects because they will be priced closer to par value. A is incorrect because the spot yield curve is derived from the most recently issued and actively traded government, not corporate, bonds. C is incorrect because seasoned government bonds tend to be less liquid than newly issued ones because they are typically owned by buy-and-hold investors. 问：on the run到底是指 交易活跃 还是指 近期发行?

老师可以再解释一下A么，对ED的定义还是有点不太清楚

Coupon bond yields and forward interest rates can be observed directly from market transactions. 问：这题我从新问一遍，视频我看懂了 后来。但是问题又来了 par curve的每一点的其实都是coupon rate吧，因为par的YTM=CR,所以难道CR不是现成的吗，所以不是可以基于观察所得吗？

老师B和C公式是什么啊？
