On June 2nd 2008, NASDAQ OMX Nordic introduced post trade anonymity on the Helsinki market and on the five most traded shares in Stockholm. That decision was based on member consultation conducted at the end of 2007 and in early 2008. 

Following further consultation in February and March 2009, NASDAQ OMX has decided to:
 - Remove the anonymity for the five shares  on the Stockholm market, and
 - Change to have post trade anonymity for only the five largest shares listed in Helsinki. 

The five shares at NASDAQ OMX Helsinki which will keep the post trade anonymity are: 
 - Nokia Oyj (NOK1V), 
 - Fortum Oyj (FUM1V), 
 - UPM-Kymmene Oyj (UPM1V), 
 - Sampo Oyj (SAMAS), 
 - Stora Enso Oyj (STERV)

The change in the post trade anonymity functionality on the Helsinki and Stockholm markets will be implemented in SAXESS as of April 14th, 2009. 

As a result of the change, the member identity will be displayed in the market data feed and in SAXESS trade ticker for all trades in equities and equity related instruments in Stockholm and Helsinki except for the five Finnish shares listed above. 
Member identity in trades for these five shares will be made public at the end of each trading day. These member identities will continue to be disseminated at CLSD-state as a specific Trade Information Multicast described in the XTP.
