Lysaker, 17 November 2010 The settlement day for EUADEC-10 and CERDEC-10 is approaching, with 1 December 2010 as the last trading day. NASDAQ OMX Commodities would like to remind the members of the following: The net sellers must ensure that all European Union allowances (EUAs) and certified emission reductions (CERs) are transferred to the clearinghouse's registry account within 20.00 CET on the last trading day, 1 December 2010. Account numbers for delivery: • EUADEC-10 - DK-121-451-0 • CERDEC-10 - DK-121-4969-0 The daily margin call for EUADEC-10 and CERDEC-10 will increase considerably the last weeks before the last trading day 1 December 2010 and the instruments' correlations will be reduced, giving less margin credits the last weeks. The increase reflects the approaching settlement and net buyers must have cash equal to the net settlement on their bank accounts within 11.00 CET 2 December 2010 at the latest. The net sellers may pre-deliver EUAs and CERs in advance of the last trading day. Pre-delivered EUAs and CERs will reduce the net sellers' need for extra collateral. Trading and clearing of EUADEC-10 and CERDEC-10 are closing at 18.00 CET on the last trading day.
