NO.PZ2019011002000007 问题如下 BonB is a 4-yeannucoupon bonwith a pvalue of $1000, ancoupon rate of 6%. The risk-neutrprobability of fault (the hazarrate) for eate for the bonis 1.50% anthe recovery rate is 25%.Li is a cret analyst in a wealth management firm. He is consiring a future interest rate volatility of 20%.The current spot rates anforwarrates are shown in the table below:He built a binomiinterest rate tree using his volatility estimation anthe current yielcurve. The Binomiinterest rate tree is shown below:Accorng to the information above, whis the fair value of Bon A.1098.14 B.1144.63 C.1251.35 A is correct考点使用二叉树对有风险的固定利率债券进行估值解析首先利用二叉树模型，计算VN(Value of the bonassuming No fault）; 得到债券的VN1144.63下面就要计算债券的CVA。第一步计算二叉树上每期的exposure，如te 4的exposure为1060;te 3的exposure为0.1250×980.75+0.3750×1005.54+0.3750×1022.86+0.1250×1034.81+60=1072.60te 2的exposure为0.25×1008.76+0.50×1043.43+0.25×1067.73+60=1100.84te 1的exposure为0.50×1063.57+0.50×1099.96+60=1141.76有了每一期的Exposure，可以计算LGLoss given fault），有公式LG= exposure × (1-recovery rate)已知Hazarrate为1.500%，则每一期的POS（Probability of survival）为(100%-1.5%)1=98.5%(100%-1.5%)2=97.0225%(100%-1.5%)3=95.5672%(100%-1.5%)4=94.1337%(100%-1.5%)5=92.7217%已知每一期的POS，则可以算出每一期的POProbability of fault）折现因子（）可以题干信息中获得；最终PV of expecteloss = Expecteloss ×。我们可以得到如下表格所以该债券的Fair value为1144.63 – 46.4915 = 1098.1385 用spot rate将无违约的fair value计算出来，是1144.63，因为减去违约补偿，一定比1144.63小，所以选A，考试的时候是不是也可以类似这样选一个
