Problem 11-26 Impact of credit ratings on cost of capital (LO11-3) Northwest Utility Company faces increasing needs for capital. Fortunately, it has an Aa3 credit rating. The corporate tax rate is 40 percent. Northwest's treasurer is trying to determine the corporation's current weighted average cost of capital in order to assess the profitability of capital budgeting projects. Historically, the corporation's earnings and dividends per share have increased about 73 percent annually and this should continue in the future. Northwest's common stock is selling at $79 per share and the company will pay a $6.30 per share dividend (01). The company's $126 preferred stock has been yielding 4 percent in the current market. Flotation costs for the company have been estimated by its Investment banker to be $3.00 for preferred stock. The company's optimum capital structure is 55 percent debt, 10 percent preferred stock, and 35 percent common equity in the form of retained eomings.
