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 droughtstricken areas to pumps that remove high water volumes in flooded areas. You report directly to the CFO. Your boss has asked you to calculate the WACC in preparation for an executive retreat.

c. Total book value of debt outstanding, is $50 million.
