Answer: 10%
Explanation:
If CC finances with 40% debt.
Return on Equity = Net Income/ Equity
Equity = Assets * ( 1 - debt)
= 2,000,000 * ( 1 - 40%)
= $1,200,000
Debt will therefore be;
= 2,000,000 -1,200,000
= $800,000
Net Income = (Earnings before Tax and Interest - Interest) * (1 - Tax)
EBIT = Basic earning ratio of 30% = 30% * 2,000,000
= $600,000
Net Income = [600,000 - ( 800,000 * 10%)] * ( 1 - 25%)
= $390,000
Return on Equity = 390,000/1,200,000
= 0.33
= 33%
If CC finances entirely with common stock
Net Income = Earnings before Tax and Interest * (1 - Tax)
= 600,000 * ( 1 - 25%)
= $450,000
Return on Equity = Net Income/ Equity
= 450,000/2,000,000
= 0.23
= 23%
Difference between financing with 40% debt and financing entirely with equity
= 33% - 23%
= 10%
