Subscriber note: Platts to extend feedback period for copper concentrate

Platts has decided to extend the feedback period for its proposal to reduce the frequency of assessment for copper concentrate treatment and refining charges, CIF Japan (symbols AAFGC00 and MMCCJ00). Platts is seeking to determine whether reports of CIF Japan business occurring more frequently than semi-annually or quarterly support a spot or monthly-negotiated assessment with sufficient liquidity and repeatability. Please provide any additional feedback by July 15 to Karen McBeth, karen.mcbeth@platts.com, or to Alvin Yee, alvin.yee@platts.com or Mayumi Watanabe, mayumi.watanabe@platts.com.
