Subscriber note: Physical iron ore eWindow launch on March 22

Following extensive consultation with industry participants, Platts plans to facilitate the Market on Close assessment process for iron ore through eWindow technology from March 22, 2013. Participants in the Platts MOC assessment process will be able to submit bids or offers for publication directly through the eWindow technology, or through an editor, who would then publish bids and offers using the software. Participation in the process through either channel is subject to Platts counterparty acceptance review. Participants are expected to apply the same credit relationships and criteria prevailing in the traditional marketplace to the MOC assessment process. When Platts editors publish bids and offers on behalf of a company that submits data to an editor, counterparty credit settings are set to "open" for regular participants in the assessment process, unless companies have notified Platts in advance of any restrictions. If you are submitting information through an editor and have not already notified Platts of any counterparty credit restrictions, please provide notification at least one hour prior to the start of the MOC process, if any counterparty credit filters need to be modified. eWindow provides direct entry and management of credit filters, which should be those normally applied in the marketplace, for companies participating directly through the technology. Platts provides training to participants interested in learning the use of the technology. Please send all feedback and comments to iodex@platts.com and pricegroup@platts.com
