Where property located in the PRC is held or being acquired for development and where the residual method is used as the primary basis for the valuation (see rule 8.24), the relevant party should obtain an acceptable PRC legal opinion (as described in rule 8.13(1)) which describes all consents, permits and regulations which need to be obtained or satisfied in respect of the development, or proposed development upon which any valuation is based. Such opinion should confirm whether and to what extent consent has been obtained for the proposed development and all such information should be included in the valuation report and in the relevant document.
