What does Weighted Average Cost of Capital (WACC) represent for a health system?

• A. The average required return of all sources of capital (debt and equity), used as the discount rate in capital budgeting.
• B. The minimum return required by customers.
• C. The historical cost of assets.
• D. The tax rate applied to profits.

Answer: (A)

WACC measures the average rate of return required by all sources of capital that fund a health system, weighted by how much each source contributes. In other words, it reflects the opportunity cost of the capital tied up in debt and equity and serves as the discount rate used when evaluating capital investments. When you forecast a project’s cash flows, you compare them to this hurdle rate: if the project returns exceed WACC, it’s adding value; if not, it may not justify the investment. The debt portion often has tax implications that reduce its cost, which is incorporated into the overall rate, alongside the cost of equity.

The other statements don’t fit because WACC is not about the minimum return expected by customers, not the historical cost of assets, and not the tax rate on profits.
