Law360, New York (June 18, 2012, 1:05 PM ET) -- Deutsche Boerse AG has sued European regulators over their rejection of its proposed $9.7 billion merger with NYSE Euronext Inc., arguing that regulators didn't properly consider antitrust concessions the stock exchange operators agreed to make, the European Commission said Saturday.
The commission blocked the transatlantic merger in February over competition worries, especially concerns that a tie-up would have given the two companies control over more than 90 percent of the global market in exchange-traded financial derivatives based on European underlyings.
