Concept of cost of capital Mace Manufacturing is in the process of analyzing its investment decision-making procedures. Two projects evaluated by the firm recently involved building new facilities in different regions, North and South. The basic variables surrounding each project analysis and the resulting decision actions are summarized in the following table.

Basic Variables	North	South
Cost	$6 Million	$5 Million
Life	15 years	15 years
Expected Return	8%	15%
Least-cost Financing
Source	Debt	Equity
Cost (after tax)	7%	16%
Decision
Action	Invest	Don't Invest
Reason	8% > 7% cost	15% < 16% cost

a. An analyst evaluting the North facility expects that the project will be financed by debt that costs the firm 7%. What recommendation do you think this analyst will make regarding the investment opportunity?

b. Another analyst assigned to study the South facility believes that funding for that project will come from the firms retained earnings at a cost of 16%. What recommendation do you expect this analyst to make regarding the investment?

c. Explain why the decisions in parts a and b may not be in the best interests of the firms investors.

d. If the firm maintains a capital structure containing 40% debt and 60% equity, find its weighted average cost using the data in the table.

e. If both analysts had used the weighted average cost calculated in part d, what recommendations would they have made regarding the North and South facilities?

f. Compare and contrast the analysts initial recommendations with your findings in part e. Which decision method seems more appropriate? Explain why.
