I'd now like to turn the call over to Mark Rohr. Mark.Mark Rohr Thanks, Jon, and welcome everyone to today's call. It's a pleasure to be here and I'm honored to be joining as CEO of Celanese and we all look forward to your questions after our remarks. Before I get into a few details on this quarter, I'd like to highlight some recent accomplishments that we are particularly excited about. In March, we received key government approvals to produce ethanol for industrial use at our Nanjing facility. This is a significant milestone as we move the coal-based ethanol opportunity closer to reality. Additionally, continued advancements in TCX catalyst technology, have allowed us to expand the capacity of this plant by 30% to 40% without capital addition, getting us to about 275,000 tons. We have begun construction and anticipate this unit will be operational in the middle of 2013.
