There is some loss in the system; it's fairly small and it's being dealt with. It's money flowing through the pipeline, so you look for every opportunity you can find to reduce those losses. There is also a lot of energy used to move the gas. Gas has a fairly low energy density, so it's fairly expensive to move long distances, but the losses are relatively small, and industry is moving pretty consistently to try to reduce those losses.
