Value in use is computed in two steps: project the cash inflows and outflows expected from keeping the asset in use and from eventually disposing of it, then discount them at a suitable rate. Five elements must be captured: the cash flow estimate itself; expectations about how the amount or timing of those flows might vary; the time value of money, taken as the current risk-free market rate; the price the market charges for bearing the asset's inherent uncertainty; and other market factors, illiquidity among them, that participants would price in. Variability, the uncertainty price and the other factors may be built into either the cash flows or the discount rate, but whichever route is taken the result must be the probability-weighted average across all outcomes. Appendix A gives further guidance on present value techniques.
