PRICING NOTICE: Correction to published counterparty indicator of the copper concentrates index

Fastmarkets has identified and corrected historical errors where the weekly counterparty indicator was published incorrectly in the copper concentrates newsletter.

This has not resulted in any corrections to Fastmarkets’ copper concentrate treatment and refining charge (TC/RC) index because the correct value of the counterparty indicator was used in the normalization procedures.

The correction only affects the counterparty indicator, as published in the weekly copper concentrates newsletter.

On newsletters published in August the table showed a counterparty indicator of $8.60 where it should have been $7.42. On newsletters dated June 28 and July 5, the indicator was published as $13.47 when it should have been $12.32 and $8.60 respectively.
