Exercise 1 : Barton Industries expects that its target capital structure for raising funds in the future for its capital budget will consist of 40% debt, 5% preferred stock, and 55% common equity. Note that the firm's marginal tax rate is 25%. Assume that the firm's cost of debt, rd, is 7.6%, the firm's cost of preferred stock, rps, is 7.1% and the firm's cost of equity is 11.6% for old equity, rs, and 12% for new equity, re.

Question 1 : What is the firm's weighted average cost of capital (WACC1) if it uses retained earnings as its source of common equity? Do not round intermediate calculations. Round your answer to three decimal places.

Question 2 : What is the firms weighted average cost of capital (WACC2) if it has to issue new common stock? Do not round intermediate calculations. Round your answer to three decimal places.

Exercise 2 : Bellinger Industries is considering two projects for inclusion in its capital budget, and you have been asked to do the analysis. Both projects' after-tax cash flows are shown on the time line below. Depreciation, salvage values, net operating working capital requirements, and tax effects are all included in these cash flows. Both projects have 4-year lives, and they have risk characteristics similar to the firm's average project. Bellinger's WACC is 10%.
