SUBSCRIBER NOTE: Platts corrects NWE butadiene commentary, May 23

In the NWE butadiene commentary, published in the Olefinscan, Volume 29, Issue 20, May 23, 2014, and on PCA505, a reference to Total Petrochemicals having confirmed settling the NWE June butadiene contract price at Eur975/mt FD NWE was incorrectly published. This has been corrected and any reference to Total having confirmed the NWE butadiene June contract has been removed. Please send comments and feedback to petchems@platts.com.
