A company faces increasing needs for capital. Fortunately, it has a Aa3 credit rating. The corporate tax rate is 40%. The company's treasurer is trying to determine the corporation's current WACC in order to assess the profitability of capital budgeting projects. Historically, the firm's earnings and DPS have increased about 7.2% annually and this should continue in the future. The firm's common stock is selling at $62 per share, and the company will pay a $2.50 per share dividend (D1). The company's $92 preferred stock has been yielding 5% in the current market. Flotation costs for the company have been estimated by its investment banker to be $4.00 for preferred stock. The company's optimum capital structure is 30% debt, 20% preferred stock, and 50% common equity in the form of RE.
