Can I have answer for part 6 please?

4. The McGonigall Company has just recently paid a dividend of $2.50 per share. Their dividends have been growing at a rate of 5% over the last several decades, and will most likely continue at that rate for the foreseeable future. Their stock is currently selling for $40.00 per share. If McGonigall were to issue new stock, they would incur flotation costs of 8%. What are the costs of internal equity and external equity for McGonigall? (4 pts.)

5. If the McGonigall company (from #4 above) has bonds with a 20-year maturity and a 6% coupon rate that are selling at a price of $920 (assume a $1,000 par value) what would be the before-tax cost of debt for the company. Also what would be the cost of equity using the bond-yield-plus-risk-premium approach if we assume that McGonigall is at the lower end of the risk premium range? How does this method of calculating the cost of equity compare with what you found in #4 above, and which estimate would you prefer to use and why? (6 pts.)

6. If the McGonigall Corp. (again, from above) has 3 million shares of common stock outstanding, 40,000 bonds outstanding, and 400,000 shares of preferred stock which currently sells for $25 per share (selling new shares would incur flotation costs of 6%) and pays a dividend of $2.90, what is its weighted average cost of capital (WACC) if the firm has a 40% marginal tax rate? Use the information in questions #4 and #5 to help you in this calculation, and assume that they use the cost of internal equity as calculated in #4. Also, what would be McGonigalls weighted average cost of capital if they used external equity instead? (12 pts. total)
