WACC and Optimal Capital Structure
F. Pierce Products Inc. is considering changing its capital
structure. F. Pierce currently has no debt and no preferred stock,
but it would like to add some debt to take advantage of the tax
shield. Its investment banker has indicated that the pre-tax cost
of debt under various possible capital structures would be as
follows:
Market Debt-to- Value Ratio (wd) Market Equity-to-
Value Ratio (ws) Market Debt-to Equity Ratio
(D/S) Before-Tax Cost of Debt (rd)

F. Pierce uses the CAPM to estimate its cost of common equity,
rs, and at the time of the analysis the risk-free rate is 5%, the
market risk premium is 7%, and the company's tax rate is 25%. F.
Pierce estimates that its beta now (which is "unlevered" because it
currently has no debt) is 0.9. Based on this information, what is
the firm's optimal capital structure, and what would be the
weighted average cost of capital at the optimal capital structure?
Do not round intermediate calculations. Round your answers to two
decimal places.
