问题如下：
A bond has a credit spread over the risk-free rate of 1.5%, a default probability per year of 0.6%, and an expected recovery rate of 30%. What is the expected return in excess of the risk-free rate?
解释：
The expected loss rate is 0.6% × (1 − 0.3) = 0.42%. The expected return in excess of the risk-free rate is therefore 1.5% − 0.42% or 1.08%.
一个债券的spread=1.5%，违约概率=0.6%pa，RR=30%，求这个债券的超过rf的回报率是多少？
The expected loss rate =0.6% × (1 − 0.3) = 0.42%.
The expected return in excess of the risk-free rate = 1.5% − 0.42% or1.08%.
