Beginning in Slide 4. Coating Resins delivered sales of $387 million, a 6% increase versus the third quarter of 2010. The increase was driven by 10% higher selling prices and favorable currency exchange impact of 6%. We continue to maintain good pricing discipline and have achieved $39 million of selling price increases in the quarter, more than covering the raw material cost escalation. This was partially offset by the 10% volume decline due to weaker demand across a number of global industrial markets, with the greatest drops seen in Europe.

Coating Resins operating earnings of $18 million for the quarter were down about 8% versus earnings of $19.5 million in the third quarter of 2010.Moving to Additives Technology. Slide 6 shows sales in the segment of $71 million, an increase of 7% versus the third quarter 2010.

Selling volumes were down by 7% due primarily to the softening demand environment that has impacted many of our global markets. Order visibility in this segment, however, remains good and we are still getting healthy forecast from customers for our specialty product lines, which remain in tight supply as we are nearing the completion of our expansion work.
