Thanks for the prompt reply.
But I have a question. The asset will never have a book value of 0 since its is going to be depreciating by 4% ever year. It will come very close to 0, but it will never be 0.
How can I set the yearly periods to depreciate the value of the asset by 4% for life. Is there a smarter way of doing it rather than, creating a ridiculous no. of periods.
