The Nordic Exchange to introduce post trade anonymity


Press release, December 19, 2007                                                

The Nordic Exchange to introduce post trade anonymity 
                          
In May 2008, OMX Nordic Exchange will commence post trade anonymity in trading. 
The Helsinki and Iceland markets will implement post trade anonymity to all     
equity-related markets including First North. In Stockholm, this concerns the   
five most traded shares. Following the introduction of post trade anonymity, the
member identity is removed from the market data feed and SAXESS trade ticker.   

Where as OMX Nordic Exchange Helsinki and Iceland will implement post trade     
anonymity in all equity-related markets including First North, the Nordic       
Exchange in Stockholm will introduce post trade anonymity in the five most      
traded shares, which currently are Ericsson B, Volvo B, TeliaSonera, Nordea, and
H&M B. These five shares represent 33 percent of the total turnover in Stockholm
based on turnover of individual shares in January-September 2007.               

OMX Nordic Exchange in Helsinki, Iceland and Stockholm have decided to adopt    
post trade anonymity following the results of extensive customer consultation   
carried out by OMX in the spring of 2007. OMX Nordic Exchange will not introduce
post trade anonymity in Copenhagen based on the results of the customer         
consultation.                                                                   

“Anonymous post trading has proven to have positive effects on market           
efficiency. Also, trade anonymity reduces market impact costs. All in all, post 
trade anonymity is an important factor for the Nordic Exchange to further       
attract automated trading volumes,” says Jukka Ruuska, President of Nordic      
Marketplaces at OMX.                                                            

Post trade anonymity is a standard in all major European and U.S. exchanges, and
its adoption is expected to further increase the efficiency of securities       
trading.
