问题如下图：
选项：
A. 
B. 
C. 
解释：
如果用老师上课讲的公式：pvRI2015＝（RI2015×0.7）/（1＋10%-0.7）＝2.814，
再折回2011年：2.814/（1+10%）4，需要折4年，结果等于1.922。和答案解析不同。

The multistage resiincome mol, is: The first step is to calculate resiincome per share for years 2012 2014:ROE = earnings / book valueGrowth rate = ROE × retention rateRetention rate = 1 (vin/earnings)Book valuet = book valuet 1 + earningst 1 vint 1Resiincome per share = EPS equity charge per shareEquity charge per share = book value per sharet × cost of equityUnr Scenario 2, the enof 2014, it is assumethshare priwill equto book value per share. This results in the seconterm in theequation above, the present value of the terminvalue, being equto zero.Then, intrinsic value per share is:V0=R7.60+R2.52(1.10)+R2.31(1.10)2+R1.98(1.10)3=R13.29按照定义，现值PV0=BV0+PVRI，PVRI=PV0-BV0，PVRI=PV0/BV0*BV0-BV0，PVRI=P/B*BV0-BV0，题目里说的是2014年末股价share price等于账面BV，并没有说PV等于BV，如何得出P/B=1呢？

NO.PZ201512300100001208 share price等于book value就说明终值是0吗？
NO.PZ201512300100001208 Unr Scenario 2, the enof 2014, it is assumethshare priwill equto book value per share. 这说明什么呢？
这个地方不太明白，题目中给出了2014末之后P=B，那就说w=0了啊，那么题目咋又给出了w=0.7？这是啥意思啊。。。。
