Pacific Intermountain Utilities Company has a present capital structure (which the company feels is optimal) of 45 percent long-term debt, 10 percent preferred stock, and 45 percent common equity. For the coming year, the company has determined that its optimal capital budget can be externally financed with $55 million of 12 percent first-mortgage bonds sold at par and $11 million of preferred stock costing the company 16 percent. The remainder of the capital budget will be financed with retained earnings. The company's common stock is presently selling at $16 a share, and next year's common dividend, D1, is expected to be $2 a share. The company has 26 million common shares outstanding. Next year's net income available to common stock (including net income from next year's capital budget) is expected to be $105 million. The company's past annual growth rate in dividends and eamings has been 5 percent. However, a 2 percent annual growth in earnings and dividends is expected for the foreseeable future. The company's marginal tax rate is 40 percent. Calculate the company's weighted cost of capital for the coming year. Round your answer to one decimal place. %
