This morning we'll begin with introductory comments from Mark Rohr, and then field your questions.
I'd now like to turn the call over to Mark.
Mark C. Rohr - Chairman and CEO: Thanks Jon, and welcome everyone. Since our prepared remarks were released last night, I'll keep my comments brief and open the line for your questions. For the quarter, we reported adjusted earnings of $1.12 per share, which is consistent with expectations of muted seasonality in our end markets and relatively consistent performance.
Coming into the quarter we didn't anticipate favorable tailwinds from the global economy which is why we focused on Celanese specific initiatives to drive growth and I believe our results demonstrate the success we're having with these initiatives. Second quarter segment income margin expanded sequentially to 22.3% for Advanced Engineered Materials, Industrial Specialties and Consumer Specialties. We are very pleased with these results which showcase our success in delivering value to through innovation and marketing.
Segment income margin in Acetyl Intermediates was lower in Q2 than Q1 due to Celanese and customer turnarounds challenges as well as raw material supply issues at one of plants. These items alone reduced Acetyl Intermediates earnings by about $15 million in the second quarter. We generated very healthy operating cash flow of $229 million and adjusted free cash flow of $154 million positioned us well to pursue our growth initiatives and our balanced capital deployment strategy.
