The right thing at the wrong time is the wrong thing, particularly when looking at valuation dates in a Discounted Cashflow.
Cashflow profiles utilised in calculations are highly dependent upon the assumptions made. If opposing experts are instructed to use different valuation dates (or other key assumptions), the cashflows used are likely to vary greatly, which can result in significant variances in the net present value calculated by the opposing experts.
A DCF could be a useful tool for valuations. However, if the starting point is not appropriate for the circumstances of the claim it is unlikely to have success in front of a Tribunal. With the increasing use of DCF calculations in disputes it is crucial that experts make appropriate assumptions, one of those being the valuation date.
