The Third Meeting of the Parties decided in Dec. III/19 with regard to financial mechanism to request the Open-ended Working Group of the Parties to review the indicative list of the categories of incremental costs adopted by the Parties in Decision II/8 and, taking into account the experience gained by the Executive Committee, to develop an indicative list of categories of incremental costs required by paragraph 1 of Article 10 of the Montreal Protocol as amended by the Second Meeting of the Parties. The list so developed should be submitted for consideration by the Fourth Meeting of the Parties.
