\section{Building a Profitability-Valuation framework mounted on a Discounted Cash-Flow model}  \subsection{Identifying the main components of the model}  We will be using the Discounted Free Cash-Flow to Firm model (/texit{FCFF} hereafter). As its name suggests, this model effectively discounts all the cash-flows that are/can be distributed to the shareholders and debt holders of the firm. Applying (1) to the firm, we get :  $EV_{t}=\displaystyle\sum_{i=t+1}^{t+K}\frac{FCFF_i}{(1+R)^i}+EV_{t+K}$ where $EV_{t}$ is the enterprise value of the value of the firm receiving the free cash-flows ($FCFF$).
