To issue the bond, the firm will have to pay $20 in flotation costs per bond. Preferred Stock: The firm can sell a 5% preferred stock at a par value of $100 per share. The cost of issuing and selling the preferred stock is $10 per share. Common Stock: The firm's common stock is currently selling for $50 per share. This year, the firm paid $3 in dividends per share. The firm's dividends have been growing at a constant rate of 1.5% per year for the last ten years and are expected to sustain this growth rate thereafter. New common stock issue: If the firm decides to issue new common stock, its underwriter indicated that the new stocks would sell for $42 per share. Further, the firm will have to pay $2 per share in flotation costs.
