Western Electric Utility Company faces increasing needs for capital. Fortunately, it has an A (low) credit rating. The corporate tax rate is 25 percent. Westerns treasurer is trying to determine the corporations current weighted average cost of capital to assess the profitability of capital budgeting projects. Historically, the corporations earnings and dividends per share have increased at about a 6 percent annual rate.

The companys $100 preferred stock has been yielding 9 percent in the current market. Flotation costs for the company have been estimated by its investment dealer to be $1.50 for preferred stock.
