ICCO MEMBERS ACCEPT BUFFER STOCK PRINCIPLES International Cocoa Organization (ICCO) producers and consumers accepted the principles of a compromise proposal on buffer stock rules as a basis for further negotiation, delegates said. The buffer stock working group then asked ICCO Executive Director Kobena Erbynn, who wrote up the draft compromise, to flesh out details of the principles with the assistance of a representative group of delegates, they said. The working group broke up for the day, into a smaller group of five producers and five consumers to discuss administrative rules and into the group headed by Erbynn to hammer out buffer stock rules details, delegates said. Delegates said many differences of opinion still have to be ironed out. "Whenever we start getting into details the clouds gather," one delegate said. Erbynn is likely to present fleshed out details of the buffer stock rules proposal to the working group early tomorrow, delegates said. The principles of the draft proposal included establishing an offer system for buffer stock purchases rather than a posted price system, a limit to the amount of non-ICCO member cocoa that can be bought, and differentials to be paid for different varieties of cocoa comprising the buffer stock, delegates said.
