SUBSCRIBER NOTE: USG ethylene assessment unchanged for Dec 27

Tuesday's US spot ethylene prices were assessed at 25.25-25.75 cents/lb FD USG for the prompt month (AAOSR00) and 26.25-26.75 cents/lb FD USG for the forward month (AAOSS00), reflecting the assessment at the end of the Platts Market on Close assessment process at 5 pm EST.

Prices were inadvertently submitted ahead of the close on PCA 870; however, the assessment remained at that level based on latest market indications and ranges.
