The NASDAQ OMX Group, Inc., (NASDAQ: NDAQ) (NASDAQ OMX Group) owns more than 90 percent of the shares in OMX AB. NASDAQ OMX Group has submitted a request to the Board of Directors in OMX AB to initiate redemption of the shares held by the remaining minority. As a consequence, OMX AB no longer meets the requirements for a listing on OMX Nordic Exchange Stockholm, OMX Nordic Exchange Helsinki, OMX Nordic Exchange Iceland and OMX Nordic Exchange Copenhagen. OMX AB will therefore apply for delisting from the Nordic Exchange shortly. NASDAQ OMX Group, the world's largest exchange company, expects to apply for listing on the Nordic Exchange.
