At close of trading on 27 November 2009, EDX London and Oslo Børs will leave the co-operation with NASDAQ OMX Stockholm AB (“NASDAQ OMX”). The previously agreed break-up date of 19 December is thus no longer valid. After 27 November, Nordic derivatives offered by NASDAQ OMX will only be available at NASDAQ OMX Derivatives Markets. Please see the attached document for information on important changes to trading and clearing arrangements and handling of open interest due to the end of the cooperation with EDX London and Oslo Börs.
