• to estimate the life of the asset
• to estimate the cash flows during the life of the asset
• to estimate the discount rate to apply to these cash flows to get present value
In case of a stock, the assumption of going concern entails that we use perpetuity as our estimated life of a company (and hence stock) unless conditions require assumptions otherwise. The estimate of cash flow could be divided as, Free Cash Flow to Firm (FCFF) or Free Cash Flow to Equity (FCFE) depending upon the exact method of DCF valuation we choose. The discount rate used to deduce the present value should reflect the uncertainty (risk) of the cash flows and opportunity cost of capital. (Please refer to earlier section on Opportunity cost)
