PRICING NOTICE: Reduction in frequency of APT quotation

Metal Bulletin plans to reduce the frequency with which it publishes the ammonium paratungstate (APT) price quotation in Europe from Friday January 29.

The spot market is agreed to be extremely illiquid and the change is aimed at allowing Metal Bulletin to capture a larger number of data points, from as many market participants as possible.

From January 29, the frequency of publication would be reduced from twice a week, to once a month on the final Friday of the month. Publication time would still be between 14:00 and 15:00 London time.

Metal Bulletin also plans to remove the stipulation that material for delivery up to three months ahead be considered spot business.

Any of these amendments may be reverted or otherwise changed again according to the level of spot activity in the coming months.

Market participants have until January 25 to respond to this notice.
