I will now turn the call over to Peter Huntsman, our President and CEO.Peter R. Huntsman Thank you, Kurt. Good morning, everyone. Thank you for joining us. Let's turn to Slide #3. Adjusted EBITDA for our Polyurethanes division in the second quarter 2012 was $170 million, an improvement of $27 million compared to the prior year of $143 million of adjusted EBITDA. The increase in earnings was entirely attributed to improvements in our MDI urethanes volumes and margins. Sales volumes for our MDI products increased 12% compared to the prior year. We are encouraged by the strong growth in demand from our largest end markets: insulation, adhesives, coatings, elastomers and composite wood products, all of which grew at double-digit rates compared to the prior year. Despite economic concerns that dominate current headlines, sales volumes in Europe improved 15% compared to the prior year and 9% compared to the prior quarter. Most of this growth came in Northern Europe, where sales volumes for our MDI products improved 14%, whereas Southern Europe grew only 1% compared to the prior year.
