You develop the following information. Your firm has a target capital structure of 70% common equity, 5% preferred stock and 25% debt. The firm's tax rate is 25%. The firm can issue up to S200,000 worth of debt at a before-tax cost of 9%. Then it will cost the firm 11% before-tax on debt up to S400,000. After that point, the before-tax cost of debt will be 13%. The firm's preferred stock carries an annual dividend of $2 per share. The issue price of the preferred would be S25 with 1.5% of the issue price charged as flotation costs. The firm expects to have S950,000 in earnings and have a dividend payout ratio of 65%. The firm bases its cost of retained earnings on the CAPM approach. For this purpose, you determine the growth rate of the market will be 5% and the market dividend yield is 2%. The risk-free rate is 3%. The firm's beta is 1.05.
