million, the total funds raised is 1000 million, of which 750 million is

Stockholders’ investment of the bank is 100 million. Assume the required rate
of return of the stockholders’ investment is 12%.
According to the information above and use
the historical average cost approach, what is the weighted average overall cost
of capital?

13.5%
7.5%
解释：
考点：对Managing Non-deposit Liabilities的理解
答案：B
解析：
Breakeven cost rate on borrowed funds
invested in earning assets = (Interest + other operating costs) / All earning
assets = (65+10)/750 = 10%
Weighted average overall cost of capital =
breakeven cost on borrowed funds + before-tax cost of the stockholders’
investment
= breakeven cost + after-tax cost of
stockholders’ investment/(1-tax rate) × Stockholders’
invest/ Earning assets
=10% + 12%/(1-0.35)×100/750 = 12.5%
这题计算公式里的第二部分没算出来就是2.5%
