Platts MOC publishing guidelines for US Aluminum MW Premium assessment

S&P Global Platts would like to remind market participants that as part of its Market on Close assessment process for the Aluminum MW US Transaction premium, it will publish all data that may be relevant, including but not limited to firm bids and offers that are open to the marketplace at large, expressions of interest to trade with such published bids and offers, as well as confirmed trades.

Platts endeavors to publish all information received that meets Platts editorial standards, so that it can be fully tested by the market at large.

Platts will consider all firm bids and offers that it publishes as open to the market at large and executable unless informed otherwise by the market participant submitting the information. Platts seeks verification of any transaction originating from a firm bid or offer published in the Platts MOC process.

Platts would also like to remind market participants that performance is paramount, and all transactions resulting from published bids and offers should be performable within the contractual parameters. Platts will take appropriate steps to ensure the integrity of its assessments if issues of non-performance should arise.

A failure to meet Platts guidelines for participation and performance in the MOC process may lead to a review. This is to help ensure that transactional information and other data inputs used as the basis for Platts price assessments are representative of market value on an ongoing basis.
