You work for HydroTech, a large manufacturer of high-pressure industrial water pumps. The firm specializes in natural disaster services, ranging from pumps that draw water from lakes, ponds, and streams in drought-stricken areas to pumps that remove high water volumes in flooded areas. You report directly to the CFO. Your boss has asked you to calculate HydroTech’s WACC in preparation for an executive retreat. Too bad you’re not invited, as water pumps and skiing are on the agenda in Sun Valley, Idaho. At least you have an analyst on hand to gather the following required information:
1. The risk-free rate of interest, in this case, the yield of the 10-year government bond, which is 3%
2. HydroTech’s:
a. Market capitalization (its market value of equity), $100 million
b. CAPM beta, 1.2
c. Total book value of debt outstanding, $50 million
d. Cash, $10 million
3. The cost of debt (using the quoted yields on HydroTech’s outstanding bond issues), which is 5%
With this information in hand, you are now prepared to undertake the analysis.
