It is apparent then that there is presently a strong clash of expert perspectives, as regards a legitimate use of anything other than an annual benchmark pricing system to source the pricing data required in a derivation of a royalty payment of money for Mineralogy as [Royalty B] under cl 8.2 of the [Mining Agreements], as an aspect of the 'Mineralogy Royalty'. Given that clash, it is convenient to recall the observations of the President at [24] of her reasons, where her Honour had observed:
Prima facie, the standard for the calculation of [Royalty B] is the published market price for the relevant products ... during the relevant quarter. The fact that (unlike the [AB Pricing System]) the market price changes during the relevant period does not make the standard legally uncertain. How best to achieve and quantify the market price for the relevant period is a matter for expert evidence on a subject involving a well understood process that is neither ambiguous nor uncertain.
Those highly persuasive observations, which I would respectfully apply on this application, were explicitly identified and agreed with concerning cl 8.2 by Corboy J in his reasons at [118] on that appeal.
At this point, I would simply observe once again that cl 8.2 in the [Mining Agreements] does not, as regards the derivation of [Royalty B] over time, say expressly that the input data source ... must be data obtained by using the (no longer operative post early 2010) [AB Pricing System]. References seen in cl 8.2 to a FOB (shipping) price pose no real difficulty. Nor is a conversion of a C&F price to a FOB price theoretically problematic.
The pragmatic obstacle to implementing [a Royalty B] calculation, if there is a problem, is tied to the absence post March 2010 of a published annual market price for [Brazilian pellets and Mount Newman fines] (which had once been the case under the [AB Pricing System]). The Brierley methodology in lieu of using what became the now inoperative [AB Pricing System] source takes an average of the published daily spot prices for Brazilian pellets and Mount Newman fines, gathered from other publicly available industry data sources.
This clash of expert perspectives is not an issue that I can or need to resolve on a final basis for this application. For present purposes, I now hold Mr Brierley's revised and reworked reports responding specifically to, and also adopting, a number of the criticisms raised by Mr Barkas, and then reworking his earlier calculations accordingly. Against that, I have the approach of Mr Barkas for the CITIC parties which basically opines that Mr Brierley's averaging approach by using spot price data to derive the annual prices for [Royalty B] is too far removed from the terms of cl 8.2 as regards meeting the proper input of the [Royalty B] calculation formula.
