Remember the PV of perpetuity = C/r
(a) (i)
Value is $2.6mill in perpetuity discounted at the required return on equity.
Value of equity = 2.6mill/0.13 = $20million
(ii)
If the firm has $10million of debt, it must pay interest expense of 10million x 9% = 10mill x 0.09 = 0.9million every year.
Therefore the cash flows of the firm will be 2.6mill - 0.9mill = 1.7million in perpetuity. Discount it at the required return of equity.
Value of equity = 1.7mill / 0.13 = 13.07million
Total value of firm = Equity +Debt = 13.07mill + 10mill = 23.07million
(b) (i)
Cash flows are now 2.6million x (1- 0.4) = 1.56million in perpetuity.
Value of equity = 1.56mill /0.13 = 12million
(ii) Remember interest payments can be claimed as a tax deduction.
With $10million of debt, the firm pays 0.9million interest every year.
Net cash flow BEFORE tax = 2.6mill-0.9mill = 1.7mill
Net cash flow AFTER tax = 1.7mill x (1-0.4) = 1.02million
Value of equity = 1.02/0.13 = $7.85million
Value of firm = Equity + Debt = 7.85mill +10mill = 17.85million
Fairly sure it's correct. Better check it with the lecturer
