LeCompte Learning Solutions is considering making a change to its capital structure in hopes of increasing its value. The company's capital structure consists of debt and common stock. In order to estimate the cost of debt, the company has produced the following table:
Percent financed |
Percent financed |
Debt-to-equity |
Bond |
Before-tax |
with debt (wd) |
with equity (wc) |
ratio (D/S) |
Rating |
cost of debt |
0.10 |
0.90 |
0.10/0.90 = 0.11 |
AAA |
7.0% |
0.20 |
0.80 |
0.20/0.80 = 0.25 |
AA |
7.2 |
0.30 |
0.70 |
0.30/0.70 = 0.43 |
A |
8.0 |
0.40 |
0.60 |
0.40/0.60 = 0.67 |
BBB |
8.8 |
0.50 |
0.50 |
0.50/0.50 = 1.00 |
BB |
9.6 |
The company uses the CAPM to estimate its cost of common equity,
rs. The risk-free rate is 5% and the market risk premium
is 6%. LeCompte estimates that if it had no debt its beta would be
1.0. (Its "unlevered beta," bU, equals 1.0.) The
company's tax rate, T, is 40%.
On the basis of this information, what is LeCompte's optimal
capital structure, and what is the firm's cost of capital at this
optimal capital structure?

Beta levered =Beta unlevered*(1+(1-Tax Rate)*Debt/equity)
AT equity 0.80 and debt 0.20
Beta levered =1*(1+(1-40%)*0.20/0.80)=1.15
Cost of equity =Risk Free Rate+Beta levered*(Market return -risk

WACC =Weight of Equity *Cost of Equity+Weight of Debt*Cost of

Based on above calculation it is clear that option b is
correct.
option b wc = 0.6; wd = 0.4; WACC =
10.15%
