An initial consultation with market participants has indicated support, with participants noting that they would welcome an increase in the frequency of the assessment and would be more likely to use the price in its commercial contracts.

The change in frequency will allow Metal Bulletin and American Metal Market to more accurately ascertain moves in the premium, taking into account deals done in different parts of the week, resulting in a more liquid assessment.

Currently, an assessment of the premium is produced every Tuesday. Under the adjusted methodology, the premium would be assessed every Tuesday and Friday.

The specification for our P1020 premium assessment is as follows:

Aluminum P1020 delivered US Midwest
Type: Assessed range
Basis: Delivered consumer works Midwest US, premium on top of LME cash prices
Grade: P1020A or 99.7 % minimum aluminium purity
(silicon 0.10% maximum, iron 0.20% maximum)
Currency: US dollars 
Unit: per lb
Minimum lot size: 100 tonnes
Payment terms: 30 days, other payment terms normalized
