"As part of Deutsche Boerse Group, ISE was able to improve both the strength of our technology and our internal capacity to develop other business areas, and we leave the group with great respect for our colleagues in all areas of Deutsche Boerse and Eurex. As we work to ensure a smooth transition to our new owners, we see the value in combining our complementary strengths with Nasdaq, whose brand is synonymous with exchange and technology leadership, and we are committed to delivering on the value proposition that they recognized in ISE," Katz said.
