Asset values are computed using the discounted cash flow approach and the following inputs: 

Thus, we have

LaTeX Math Block
alignmentleft
P_{i,t}=\sum_{t=1}^T \frac{CF_t}{(1+r_{i,t})^t}

with  

LaTeX Math Inline
bodyP_t
 the price of asset 
LaTeX Math Inline
bodyi
 at time  
LaTeX Math Inline
bodyt
LaTeX Math Inline
bodyCF_1\dots CF_T
 the stream of future payouts, and 
LaTeX Math Inline
body--uriencoded--r_%7Bi,t%7D
 the discount rate for asset

 at time 
LaTeX Math Inline
bodyt
.

Here, 

LaTeX Math Inline
bodyr_{i,t}
 is the combination of the term structure of risk-free rates in each period  
LaTeX Math Inline

bodyT
 and the risk premia

Info

As described here,

LaTeX Math Inline
body\hat{\gamma_i}
 is a company specific risk-premia, computed as the combination of asset 
LaTeX Math Inline
bodyi
's risk factor exposures at the time of valuation or 
LaTeX Math Inline
body--uriencoded--\beta_%7Bi,t%7D
 and the market price of each risk factor
LaTeX Math Inline
body\lambda_t
  estimated from observable market prices.
