Carmel Ridge Corporation is trying to determine its optimal capital structure. The company's capital structure consists of debt and common stock. In order to estimate the cost of debt, the company has produced the table below. The applicable tax rate is 40%. The company uses the CAPM to estimate its cost of common equity. The risk-free rate is 4 percent and the market risk premium is 5 percent, while the beta without any debt (its "unlevered beta") is 0.50. What is the Beta Coefficient at 40% Debt, 60% Equity" capital structure? [NOTE: Round off your answer to TWO decimal places. No need to put "times"] * Debt-to-total Equity-to-total Before-tax assets ratio assets ratio cost of (wa) (w.) debt 0.10 0.90 5% 0.20 5.2. 0.30 0.70 6.0 0.40 0.60 6.8 0.50 0.50 7.6% 0.80
