NYSE Euronext (NYX) said a computer malfunction suspended derivatives trading 
on its Liffe market and halted price updates on its European stock indexes for 
almost an hour as equities plunged the most in 15 months.

Derivatives trading resumed at 6:10 p.m. in Paris and gauges in Paris, 
Brussels, Lisbon and Amsterdam were suspended from 4:28 p.m. to 5:20 p.m., NYSE 
Euronext said on its website today. Trading in individual equities was 
unaffected. The Stoxx Europe 600 Index tumbled 3.4 percent to 243.3, the 
biggest drop since May 7, 2010, amid concern the global economy is weakening.

“For the system to be down today is a total disaster,” said Lex Van Dam, a 
London-based fund manager at Hampstead Capital LLP, which oversees $500 
million. “This is a really scary market. It’s so busy and for people not to be 
able to get out of their positions or hedge on today of all days is really 
terrible.”

NYSE Euronext matches equity trades on its Universal Trading Platform while 
Deutsche Boerse AG (DB1), with which it’s seeking to merge, uses its Xetra 
technology and is developing a new system for all its markets. The two 
exchanges have said they will seek to save more than 51 million euros ($72 
million) by having common trading and clearing infrastructure and combining 
networks. They haven’t said whose systems they will use after the takeover is 
completed.

Euribor Futures

The Liffe system that went down today halted trading in short-term interest 
rate derivatives including Euribor futures and contracts based on FTSE indexes. 
Contracts that passed their settlement time will be settled at 6:30 p.m. Paris 
time, the exchange said.

Today’s fault was the sixth in less than two months for NYSE Euronext. The 
company’s equity indexes in France, Belgium, Portugal and the Netherlands 
didn’t update for almost two hours on July 29 and 3 1/2 hours on July 12.

That followed a June 27 glitch that stopped trading in CAC 40 stocks for more 
than 45 minutes and two incidents the previous week that delayed the start of 
trading by an hour in Paris, Amsterdam, Brussels, Luxembourg and Lisbon and 
halted transactions in the largest Dutch and Belgian stocks.

NYSE Euronext, formed when the operator of the New York Stock Exchange bought 
Europe’s second-largest exchange in 2007, has cited improving computer systems 
as a goal of its combination with Deutsche Boerse, first announced in February. 
The transaction will give Deutsche Boerse 60 percent of the combined entity, 
while NYSE Euronext Chief Executive Officer Duncan Niederauer will run the 
organization.

Italy’s FTSE MIB Index also stopped updating today, according to Borsa 
Italiana, which is owned by London Stock Exchange Group.
