You are given the task of calculating the cost of capital of KaBoom Toy Company. The company faces a tax rate of 40%. The company has 100,000 common shares and 10,000 preferred shares outstanding. Each preferred share has a par value of $60, and is currently priced at 90% of the par value. The preferred shares are paying dividends that total 5% of the par value. You estimate that the beta of the common stock is 1.5. The equity market risk premium is estimated to be 5%, and the risk-free rate is 5%. The company has just paid a dividend of $2 per share. You expect that the dividends will grow at a rate of 15% until Year 4. After Year 4, the dividends are expected to grow at a constant rate of 5% forever. You decide to employ the CAPM approach to calculate the cost of equity.
