30. INTERNATIONAL HARMONIZATION IVS (INTERNATIONAL VALUATIONS STANDARDS) IVSC undertook preparation and circulation of a Discussion Paper in 2012. Many comments were received from industry (incl. mining and accounting sectors). Now being analyzed. Key discussion items included: What methods are used for allocating value to different assets contributing to the cash flow? How is double counting avoided? Extent to which intangibles are reflected in valuations in extractive industries. What types of intangible asset are typically identified?

31. INTERNATIONAL HARMONIZATION IMVAL ( INTERNATIONAL MINERAL ASSET VALUATION COMMITTEE) Prepared draft template in January 2013 of an International Mineral Asset Valuation Reporting Template (IRT) to serve as future guidance. Draft was based on: VALMIN Code (Australasia), SAMVAL Code (South Africa), RICS Red Book (UK / Western Europe), CIMVAL (Canada), and SME Guide (USA). It also draws from, and references to, the International Valuations Standards (IVS) and the International Financial Reporting Standards, where appropriate. Next step: circulation and review of industry comments.
