Thanks Beers. You are right. That is one way, and was in the back of my mind when I asked.

I'm not an accountant so correct me if I am wrong... there is another method where you state your discount rate on yearly revenue and calculate the sum NPV and an IRR%. The discount rate (e.g. 8% should be referenced.

The second method/approach is what i assume is used in Skibum's table for Schaft.

"NPV @ 8% (after tax)$1,597,500,000, IRR 18.6% "

Accounting Q: If we used the 18.6% above as the "Weighted Cost of Capital" in Demolish40Beer's method for SC, the NPV would equal zero?
