Re-evaluating an investment decision

Timing with NPV
Isaac Nyamanza
Revalue the initial investment to its present value and discount the future cash flows to get NPV as at now. This will give you a better position for decision making.

Think now when you think about decision making.
Muhammad Habeeb
As an opinion there is no problem to take past CFs for the re-evaluation, but the decision made in the past was probably valid in that situation. So think now to see whether some "being things remain equal" is still valid or not. See cash flows in the current scenarios for technical, economical, social & legal feasibility.

The relevant things are only to be taken. The present value of the investment has to be established based on its worth today based on market and the future cash flows will have to be reassessed and discounted in todays cost of capital

It is better to consider the past cash flows up to 2004 and adjust other variables to begin your analysis of future cash flows. That way, you are considering all the possible cash flows associated with the project..

For the sake of decision making ignore all past expenditure and for the sake of re-evaluation,context and the appropriate time horizon are important,past CFs were relevant in the past and in that particular context only

Base on the past

I really think thats a great idea, you've got to take into consideration how things were in the past and then establish a link with the present so as to determine the future
