老师好，请能否大概再介绍下风险中性，风险喜好，风险厌恶的特别，我忘记了，谢谢！

请问，2013年第8题 题目B 还适用于2019的考试吗？ 似乎基础课中都没提过initial safty margin的概念。谢谢。

24题及其答案，课后题讲解老师说，计算第二阶段值，分子上要乘以衰减因子0.7，可是题目答案里，分子上没有乘衰减因子。为何呢？我试着乘以衰减因子，然后多折现一期，结果也不对。盼望指点！谢谢

老师你好，Reading 14， 16题，将AFS转成trading security，为什么只讲2008年到2009年的亏损1000块算进去？ 在进行结转的时候难道不应该把2008年放到OCI中的4000块Gain转到IS中么？最后的答案应该是C啊 。

请问老师 除了一个个现金流折现外 还有没有更快的方法算DPB？
