The company estimates that it can issue debt at a rate of r_d = 9%, and its tax rate is 40%. It can issue preferred stock that pays a constant dividend of $3 per year at $54 per share. Also, its common stock currently sells for $30 per share; the next expected dividend, D₁, is $4.00; and the dividend is expected to grow at a constant rate of 4% per year. The target capital structure consists of 75% common stock, 15% debt, and 10% preferred stock.
