Lysaker, 22 April 2009 Nord Pool ASA is currently experiencing some irregularities with the information provided on the web and real time feed. However, this has no effect on the trading and clearing processes at Nord Pool. The transparency of information and stability of our information channels web and feed are of the highest priority for Nord Pool. We therefore apologize for any inconvenience the irregularities below have caused. Several measures are taken to rectify these as soon as possible. However, due to necessary testing and quality assurance of the back office applications for the web and feed, some of the minor issues may not be corrected before Monday 27 April. The correct price and volume information for exchange trades can be accessed through Click Trade. Information regarding OTC trades may be viewed at http://www.nordpool.com www.nordpool.com under “Non-Exchange Trades”. FEED AND WEB Incorrect contract time information of non-exchange trades All OTC trades are being disclosed with registration time rather than contract time. This will be corrected within market opening Thursday 23 April. Incorrect price data on WEB and feed OTC deals are wrongly included in the calculation of the fields “FirstPrice”, “LowPrice “and “HighPrice” in exchange (ClickTrade) deal records. The OTC deals are not a part of the calculation of these prices. WEB Incorrect quotation on previous trading days The overview for the previous five exchange trading days are showing one day delay, meaning Sunday shows the quotations for Friday, Friday shows the quotations for Thursday etc. Open Balance on emission contracts is wrong In the information distributed on the web, the open interest is divided by 1 000 compared to actual open interest. This will be corrected within market opening Friday 24 April. FEED Closing prices are not distributed for the time being As a temporarily work around, the prices may be obtained from Nord Pool website. Open Balance on power derivates is wrong In the product messages distributed on our real time feed open interest is 1 000 times higher than factual. The temporary work around is to divide by 1 000 or get the open balance from Nord Pool web. This will be corrected within market opening Thursday 23 April. "BestBid" and "BestAsk messages are missing The feed does not distribute “BestBid “and “BestAsk” messages. However, the same information can be retrieved from the “OrderBookBid” and “OrderBookAsk” messages until this is fixed. Field “MarketCode” contains numeric market codes instead of names “Messages Product” and “ExternalDeal” use a field named “MarketCode”. Previously this field contained the name of the market (for instance “Nordic”). It now contains the numeric market code (for instance “13” for market “Nordic”).
