问一道题:NO.PZ2018091705000024 [ CFA III ]

问题如下:

Allen is an investment manager, who recently recruited a new customer, Polly. Polly invested $100,000 in an asset for 20 years that promises to offer an annual capital gain of 8%, which are deferred capital gains. The investment account is expected to be taxed 15% when capital gains are realized. Assume at beginning of the investment period, the investment has a cost basis of $80,000, Calculate the post-tax value of the investment after 20 years later.

选项:

A.

$411,181.36

B.

$372,756.35

C.

$ 408,181.36

解释:

C is correct.

考点Deferred Capital Gain Tax

解析首先我们计算一下B = 80,000/100,000=0.8

接着我们运用税基基础不等于1时候的Deferred Capital Gain Tax计算

lFV=PV[(1+R)N[(1+R)NB]×TCG]100,000[(1+8%)20[(1+0.08)200.8]×15%]=408,181.36{l}FV=PV{\lbrack{{(1+R)}^N-\lbrack{(1+R)}^N-B\rbrack\times T_{CG}}\rbrack}\\100,000{\lbrack{(1+8\%)}^{20}-{\lbrack{(1+0.08)}^{20}-0.8\rbrack}\times15\%\rbrack}=408,181.36

请问这里为什么不能用:(1+8%)*20✘(1-15%)-(1–80/100)✘15%呢?我这里有点混乱了,我这个做法错在哪里呢?

嗨,爱思考的PZer你好:


首先,Tcg=15%,这是资本利得所要交的税,也就增值的那部分的资本应该要扣15%的税

你这个式子上来就错了:(1+8%)^20*(1-15%),这等于说是对20年后,账户的全部金额扣税了
