问题如下:

8. Based on Exhibits 2 and 3 and the multistage RI model, Castovan should estimate the intrinsic value of TTCI to be closest to:

选项:

A.

€54.88.

B.

€83.01.

C.

€85.71.

解释:

C is correct.

Residual income per share for the next three years is calculated as follows.

Because Castovan forecasts that residual income per share will be constant into perpetuity, equal to Year 3 residual income per share, the present value of the terminal value is calculated using a persistence factor of 1.

Present value of terminal value = 8.54(0.087×58.25)(1+0.0871)(1+0.087)2\frac{8.54-(0.087\times58.25)}{(1+0.087-1)(1+0.087)^2}

= 3.47(0.087)(1.087)2\frac{3.47}{ ( 0.087 ) ( 1.087 ) ^2} =33.78

So, the intrinsic value of TTCI is then calculated as follows.

V0=\frac{45.25+3.88/1.087+3.68/(1.087)^2+33.78}=85.71

如题,谢谢!

同学你好,请看以下讲义截图,你是需要助教写一下下面4种多阶段计算PVRI的方法中本题对应的黄色的那个计算公式吗?

请注意,题目这里说的是从第三年RI就开始进入永续不变了哦~~

黄色的PVRI的公式类似于永续年金公式,PVRI2 = RI3/r折现的时候是折现到第二年的年末,所以最后只需要再向前折现两年就可以了哦~~

或者你如果是按照李老师上课的公式PVRI(t-1) = RI(t-1)/r来计算的话,是需要从第四年开始计算的,但是由于RI从第三年开始保持不变,所以RI4=RI3,虽然带入的是RI3的值,其实本质此时这个分子已经是RI4了

即最后的V0公式是V0 = RI1/(1+r) + RI2/(1+r)^2 + RI3/(1+r)^3 + PVRI3/(1+r)^3(其中PVRI3 = RI3【也就是RI)/r】


这样计算出来的结果和答案是一样的哦~~

谢谢老师我按照用RI3/r 然后再折现算出来了。 再请教一下老师,这里是不是用李老师的方法就完全用不到persistence factor了?是因为题目说RI3= RI4以后都一样了么?加入题目没有说这些都一样,我是不是需要用RI3/(1+r-w)来求RI4呢?

同学你好,“这里是不是用李老师的方法就完全用不到persistence factor了?是因为题目说RI3= RI4以后都一样了么?”——是的,此时属于讲义截图中第一种情况,RI保持恒定,所以可以类比优先股的方式求PVRI,不用persistency factor

“加入题目没有说这些都一样,我是不是需要用RI3/(1+r-w)来求RI4呢?”——不一定,要看题目给的条件是什么,如果直接给终值时间点的Price和Book value的关系,则适用于上面讲义截图的第4种计算方式计算PVRI

如果题目给了persistency facotor的具体数值,那就适用于讲义截图倒数第二种的计算方式来计算PVRI了,此时RI4 = RI3*w,你可以用RI4带入倒数第二个公式求PVRI3=RI3*w/(1+r-w),或者直接用RI3带入PVRI2 = RI3/(1+r-w),注意PVRI两种方法落在的时间点不同即可
