Based on your understanding of the concept of cost of capital, which of the following statements are valid? Check all that apply. Companies have free cash flow that is available for distribution, and investors expect to earn a certain required rate of return if it is invested.

The weighted average cost of capital (WACC) is considered the overall rate expected to generate required returns for investors, but companies do not use it while discounting project cash flows. The required rate of return for long-term debt capital funding is incorporated separately in project analysis, because it is not included in the weighted average cost of capital (WACC)
