I read that and it pretty much says the same thing as slide 41 only in a more convoluted way.
Let me give you an example for clarification.
CAPEX cost 1 billion (example only)
TECK elects to fianance 700 million through debt and put up 300 million itself. (this meets requirement in 14.3 for a minimum 60% debt financing).
Assume CAPEX goes over by 100 million. Then TECK will finance 25 million (CUU share) through a loan at prime + 2% and TECK pays its onw share of 75 million. A similar loan will be provided by TECK to CUU if the pre-production decision costs exceed 220 million (see my previous post for details)
Now fast forward to the first day of copper production. From this point forward, 90% of the yearly net cash flow is used to pay off the debt in the following order: 700 million financing, then TECK's own money (plus interest) and the loan to CUU last. While all those debts are paid, CUU (or whoever buys us) still receives 25% of the remaining 10% of yearly net cash flow.
After all debt is paid, CUU will then start to receive 25% of the yearly net cash flow.
This shows how CUU, or a new buyer for our 25% share, does not have to put up a single penny for the project and will start receiving annual cheques the moment copper starts to come out of the ground.
