Subscriber note: Corrects August 2 US butadiene spot assessment, contract price

Because of an editing error, the US butadiene spot assessment and contract price published in the August 2, 2013, edition of Olefinscan were incorrect. The correct spot assessment should have read 42.50-43.50 cents/lb CIF USG, while the contract price should have read 40-47 cents/lb for August. The assessments can be found in Platts Petrochemical Alert on PCA313 as well as Olefinscan. For comments or queries please contact petchems@platts.com and pricegroup@platts.com.
