These bonds currently are selling for $1120. The firm's tax rate is 40% and the flotation costs of issuing bonds are 4%. The firm's stock sells for $40/share, currently pays for $1.20 in dividends. Investors expect these dividends to grow at 6% per year forever. The flotation cost of issuing shares is 8%. The book value of equity is $8/share. Going forward, the firm plans to meet 90% of its equity needs internally and 10% of it externally. The firm does not plan any changes in its capital structure.
