DCF is a valuation tool used to find the intrinsic value and then begin running them through the steps: calculate FFCF (explaining what it is), calculate the WACC (also explaining what it is), discount the FFCF using the WACC to get to the present value, calculate the terminal value (explain what it is), discount the terminal value using the WACC to get to the PV and then add this figure to the PV for the discounted FFCF.
