i think FV is considered as firm value...not future value....
We often use some indicators such as sales and EBITDA to measure the profitability of the company. Apparently, the relation between the company’s profitability and ratios like FV/SALES and FV/EBITDA should be negative. Neither SALES nor EBITDA is a misleading number. We use FCF to be considered as the real income the company made. If FCF is lower than ever, the company might be in the recession or decline stage. And if FCF is negative, the risk of this company is too large and absence of competition.
