1 October 2008 Exchange Notice All Trades Average Price calculation Yesterday we informed you about errors in the calculation of the All Trades Average Price on the Danish bond markets for Monday September 29th and Tuesday September 30th. We decided to perform a rollback and use the TARGIN message AfeedBondPriceTurn for All Trades Average Price until the system error has been corrected. This is the same functionality that was used in TARGIN until 26 September. From today, Wednesday 1 October, the All Trades Average Price is available in the TARGIN feed in the message: 20.14 AfeedBondPriceTurn. This solution will continue until the error has been corrected. From Wednesday 1 October the TARGIN message InstrumentSummary will not be disseminated and the All Trades Average Price will not be in the TARGIN TradeStatistics message until the error has been corrected. We will inform you well in advance when starting to use the InstrumentSummary and TradeStatistics messages for the All Trades Average Price again. Previously communicated All Trades Average Prices for September 29th and September 30th might contain errors and should not be used. Corrected average prices (in csv format) have been sent out to subscribers of the Official Price List. If you did not receive the lists yesterday, you can get a copy by sending an e-mail to mpo_cph@nasdaqomx.com. We apologize for any inconveniences this might have caused you.
