SUBSCRIBER NOTE: Platts clarifies aluminum CIF Japan quarterly premium assessment

S&P Global Platts wishes to clarify its CIF Japan aluminum forward-quarter premium assessment methodology.

The final assessment range is published when a sufficient number of transactions of next-quarter contracts, of minimum 500 mt/month, have been concluded to reflect a repeatable contract assessment value. This is often the case by the first date of the quarter.

Should contract negotiations extend beyond the first date of the quarter, Platts will continue to report on the negotiations as they evolve, but no quarterly assessment value will be published until a sufficient number of transactions have been concluded.

Platts is also clarifying that cargoes in the quarterly contracts leave ports during the quarter being negotiated for, rather than during or following the month of transaction.

Platts surveys a broad range of market participants from across the aluminum supply chain in compiling its assessment.
