Industrial Minerals pricing principles

Data collection criteria: Industrial Minerals reporters aim to talk to a broad sample of market participants specifically involved in the buying and selling of the mineral of interest, with a good representation of both sides of the market. All input data received is kept confidential and stored in a secure network.

Price specifications and reference units: Industrial Minerals specifications detail the material’s characteristics or quality, location and the incoterm accepted. All the reference units, such as currency and volume, are in line with recognised metals markets trading conventions. Reporters ensure that the information they receive matches these specifications.

Guidelines that control the exercise of judgment by price reporters during the assessment process: To produce the price assessment, greater weighting is generally given to actual concluded transaction data. Bids/offers are second in order of importance, followed by data sources’ own assessment of the market when they have no business to report. Industrial Minerals seeks price information for trades with a relevant minimum lot size. When volume information is available, this is also taken into consideration in the assessment process. A pricing session typically includes bids/offers, contributors’ assessment as well as concluded transactions. This means that market data will typically be contributed by several separate sources and that there is no key submitter dependency. However, should a significant proportion of the data (defined as more than 50% of the data points) on which to base the assessment be provided by a single source, the reporter, peer reviewer and the senior editorial person signing-off the price prior to publication will analyse the data and consider if the assessment should be published based on the data collected or rather not to move the price and roll it over from the previous session.

Data normalisation: Occasionally Industrial Minerals might receive price data for material where specifications differ in some element from our specifications. In such cases, when appropriate, Industrial Minerals will normalise data.

Criteria to discard pricing data: Industrial Minerals will use its expert judgment to exclude outlying or unrepresentative numbers, and discount or discard prices that it believes may otherwise be questionable and unreliable.

Procedure to ensure consistency in the price discovery procedures: All Industrial Minerals price assessments are set by a first reporter who covers that specific market, peer reviewed by a second reporter, and always signed-off and approved by a senior reporter or editor prior to publication. Price reporters are formally trained in the price discovery process and must abide by a written Code of Conduct and Pricing Procedures.

Publication of the price assessment: At the end of the pricing session, from the information that Industrial Minerals receives and reviews it sets a price range, to reflect the representative spread of prices at which business has been transacted, offered or bid.
