Petroleum reporting standard (18A.31-18A.33)
In addition to satisfying the requirements of Chapter 17 (as modified by this Chapter), a Mineral Company exploring for and/or extracting Petroleum Resources and Reserves must also satisfy rules 18A.32 and 18A.33.
A Mineral Company must disclose information on Petroleum Resources and Reserves either:—(1) under PRMS as modified by this Chapter; or(2) under other codes acceptable to the Exchange if it is satisfied that they give a comparable standard of disclosure and sufficient assessment of the underlying assets.
Note: A Reporting Standard applied to specific assets must be used consistently.
A Mineral Company must ensure that:—(1) where estimates of Reserves are disclosed, the method and reason for choice of estimation are disclosed (i.e. deterministic or probabilistic methods, as defined in PRMS). Where the probabilistic method is used, the underlying confidence levels applied must be stated;(2) if the NPVs attributable to Proved Reserves and Proved plus Probable Reserves are disclosed, they are presented on a post-tax basis at varying discount rates (including a reflection of the weighted average cost of capital or minimum acceptable rate of return that applies to the entity at the time of evaluation) or a fixed discount rate of 10%;(3) Proved Reserves and Proved plus Probable Reserves are analysed separately and principal assumptions (including prices, costs, exchange rates and effective date) and the basis of the methodology are clearly stated;(4) if the NPVs attributable to Reserves are disclosed, they are presented using a forecast price as a base case or using a constant price as a base case. The bases for the forecast case must be disclosed. The constant price is defined as the unweighted arithmetic average of the closing price on the first day of each month within the 12 months before the end of the reporting period, unless prices are defined by contractual arrangements. The basis on which the forecast price is considered reasonable must be disclosed and Mineral Companies must comply with rule 18A.30(5);
Note: In the forecast case under PRMS, the economic evaluation underlying the investment decision is based on the entity's reasonable forecast of future conditions, including costs and prices, which will exist during the life of the project.(5) if estimated volumes of Contingent Resources or Prospective Resources are disclosed, relevant risk factors are clearly stated;
Note: Under PRMS, wherever the volume of a Contingent Resource is stated, risk is expressed as the chance that the accumulation will be commercially developed and graduate to the reserves class. Wherever the volume of a Prospective Resource is stated, risk is expressed as the chance that a potential accumulation will result in a significant discovery of Petroleum.(6) economic values are not attached to Possible Reserves, Contingent Resources or Prospective Resources; and(7) where an estimate of future net revenue is disclosed, whether calculated without discount or using a discount rate, it is prominently disclosed that the estimated values disclosed do not represent fair market value.
