The issue is very complex. First of all, I think there's an assumption being made that there will be more efficiency in a track that's moved. We have not seen specific drawings and details of how that would work, so it's not entirely clear that we would have those efficiencies.
Second, as either Johan or I mentioned, we have expended $37 million in the last three years on these tracks, so we already have expended a great deal. Those costs would come in on the opposite side of the equation in terms of needing to be recouped. Without having the exact figures and exact engineering drawings, those may net out to nothing. We would have to look at the detailed information in order to be able to respond to that. My internal guess is that it would probably net out to zero.
