问一道题：NO.PZ2018101501000064

  1. CFA II
  2. Corporate Issuers

问题如下：

Company M, a manufacturer of automobile, is in the 25% tax bracket. The company is currently 37.5% debt-financed and 62.5% equity-financed, with the market value of debt and EBIT of $1 million and $0.5 million, respectively. What`s the WACC of Company M according to the MM`s proposition with tax?

选项：

A.

11.25%

B.

14.04%

C.

18.73%

解释：

B is correct.

考点：Capital Structure Theory: with tax

解析：根据公式 VL=VD+VE=EBIT∗(1−T)WACCV_L=V_D+V_E=\frac{EBIT\ast(1-T)}{WACC} 

VD = $1 million, D/E = 0.6, 求得VE = $1.67 million

代入VL = 2.67 =0.5∗(1−25%)WACC\frac{0.5\ast(1-25\%)}{WACC}  ，求得WACC = 14.04%

这道题用到的公式：V=EBIT*（1-T)/R，只是一个近似的公式对吗？

因为根据DCF模型，EBIT（1-T)其实并不等于每期的税后cash flow。

嗨，从没放弃的小努力你好：


你说没加折旧对吗？这是因为MM理论并不是要研究权责发生制和收付实现制之间的区别，而是研究最优资本结构是什么。所以它选取了损益表的数字，忽略了折旧这种会受各种会计计量方法影响的科目，其实是简化研究问题了。
