问题如下：
Company M, a pharmaceutical corporation, is going to expand its market to a foreign country. The company is in the 25% tax bracket. Matt, CFA, is evaluating the expansion project and collecting relevant information in the following exhibit. What’s the weighted average cost of capital for Company M?
选项：
A. 13.125%
B. 12.75%
C. 13.5%
解释：
B is correct.
考点：Risk Analysis
解析：根据公式WACC = wd*rd*(1-T)+we*re，其中wd和we是以市场价值为权重而非账面价值。
WACC = 30%*10%*(1-25%)+70%*15% = 12.75%
WACC不是应该按照目标资本权重吗？为什么要按照MV啊？这个知识点在什么地方？
