Explain Weighted Average Cost of Capital (WACC). The WACC for a firm can be calculated or found through research. Select two firms in the same industry. The industry may be that in which you currently work or it may be an industry in which you are interested. Calculate or find the WACC for the two firms. How do the WACCs compare? Are the WACCs what you would expect? What causes the differences between the two firms' WACCs?
