In the next couple of posts, I'll try to elaborate more on the approach I'm using to calculate NPV's. I don't claim being an expert, just sharing what I understand from it and hope it can help interested people to learn more about this concept. First let's start with the basics.
1) You need a calculator. I found this one was pretty easy to use.

2) You need to understand the different parameters
- Interest rate: value that money loses for each year that passes (8% in our case)
- Compounding: number of periods in a year where the interest is compounded (assuming 2 periods in our case)
- Cash flow: amount of money in and out of the business
3) For Schaft Creek (100%), see below the approximate stream of net cash flows (in millions) based on the 2013 FS.

Year 19: 800
|
Year -1: -825

4) Entering all these values in the calculator should give you a NPV (8%) around 520M.
Conclusion: The 2013 FS had a positive result of 513M, so the assumptions used above provide good enough results for the purpose of the exercise.
IMO.
