Asset values are computed using the discounted cash flow approach and the following inputs:
- A forecast of the future payouts to the owners of the asset (dividends and shareholder loan repayments and interest, or senior debt service)
- A term structure of risk-free rates in the relevant market on the valuation date (quarter- or month-end) and at the relevant horizon (duration)
- An equity risk premia or debt credit spread
Thus, we have
P_{i,t}=\sum_{t=1}^T \frac{CF_t}{(1+r_{i,t})^t} |
with P_t the price of asset i at time t, CF_1\dots CF_T the stream of future payouts, and r_{i,t} the discount rate for asset i at time t.
Here, r_{i,t} is the combination of the term structure of risk-free rates in each period t until investment horizon T and the risk premia \hat{\gamma_i} estimated for asset i.
As described here, \hat{\gamma_i} is a company specific risk-premia, computed as the combination of asset i's risk factor exposures at the time of valuation or \beta_{i,t} and the market price of each risk factor \lambda_t estimated from observable market prices.
