Paul Renken: Zinc we're pretty positive on actually, particularly for 2014-2015, for three particular reasons. First of all, we feel underinvestment in zinc is going to cause some supply constraints in 2014, particularly because some of the really large deposits are reaching the end of their life throughout the world, such as the Century deposit in Australia. The New Brunswick smelter is now being closed, so the availability is going to become more constrained as we head into 2014.
