Hello, I don’t know if this is the right place to ask, but you guys here seems like the right people to ask;

I am in a project where I am going to calculate a NVP for different projects, but the issue is that these investments (machines) has been made like 10 years ago so it’s not like I have a negative cash flow in period 0 due to the investment. I am therefore wondering what can be the way to calculate a NPV in such a situation. I am thinking of using the book value of the machines at the year I’m starting to calculate from as a proxy to an investment because that will be the price the company must pay to get a hold of the machines today.

Any thoughts on this?
