According to DOJ, clearance was contingent upon the International Securities Exchange (ISE),
a 100% owned by Eurex, agreeing to sell its 31.5% stake in Direct Edge, a US stock exchange.

In 2008 ISE partnered with Direct Edge when ISE equity market operations became a wholly owned subsidiary of Direct Edge.

The transaction, which is subject to the approval of the European authorities, will be submitted to the commission by 9 February 2012.
