Western Electric Utility Company faces increasing needs for capital. Fortunately it has an A (low) credit rating. The corporate tax rate is 35 percent. Western's treasurer is trying to determine the corporation's current weighted average cost of capital to assess the profitability of capital budgeting projects. Historically, the corporation's earnings and dividends per share have increased at about a 6.2 percent annual rate. Western Electric's common stock is selling at $63 per share, and the company will pay a $5.50 per share dividend (D). The company's $94 preferred stock has been yielding 7 percent in the current market. Flotation costs for the company have been estimated by its investment dealer to be $5.00 for preferred stock. The company's optimum capital structure is 45 percent debt, 25 percent preferred stock, and 30 percent common equity in the form of retained earnings.
