Does the spot price of copper have much influence on CUU price. If we are well along in negotiations wouldn't they have some longer term average price that they have already agreed upon? I' m hoping that spot price has a big influence but I can't see CUU walking into negotiations and saying "Hi the price for CUU just jumped 50 million because copper just went up another 10 cents."

Not being negative . I just haven't been in these types of negotiations so I'm curious regarding how flexible these factors are.
