The firm's investment bankers believe that investors will be willing to pay $84.00 per share and that flotation costs will be equal to $8.45 per share. Given this information, determine the difference between the investor's required rate of return, and the firm's cost of preferred stock. 1.969% 1.398% 1.683% 2.541% 2.224%
