Correction to cobalt standard-grade rationale

Fastmarkets has corrected the rationale for its MB-CO-0005 cobalt standard grade, in-whs Rotterdam, price assessment on Monday March 24, which was published incorrectly due to a reporter error.

There was a typographical error with the figure for the top end of the range being incorrect in the first line of the rationale. This read: “Fastmarkets’ price assessment for cobalt standard grade, in-whs Rotterdam, was $15.10-16.00 per lb on Monday March 24, widening down from $15.70-16.50 per lb in the previous session.”

The correct version reads: “Fastmarkets’ price assessment for cobalt standard grade, in-whs Rotterdam was $15.10-16.50 per lb on Monday March 24, widening down from $15.70-16.50 per lb in the previous session.”

The published price is unaffected by this change.

This price is part of the Fastmarkets minor metals package.
