CNBC INTERVIEW

NYSE EURONEXT PRESIDENT AND DEPUTY CEO, DOMINIQUE CERUTTI

On NYSE/ICE

THURSDAY, JANUARY 24, 2013

3:20AM

Maria Bartiromo: I’m talking right now with Dominique Cerutti, the president and deputy chief executive of NYSE Euronext who just rang the Opening Bell. Dominique good to see you.

Dominique Cerutti: Pleasure

Maria: We have been talking all over the world about the sale of NYSE Euronext and the combination of NYSE Euronext with ICE. Tell me where that stands and when you’re expecting this deal to close.

Dominique: So as we said ICE would acquire NYSE Euronext. That’s going to be at least a kind of long process. We expect to get the approvals by the end of the year — second half as usual. It’s antitrust both in the U.S and in Europe and then all the non-objections from our regulators, so we could expect to close the deal in the second part of the year.

Maria: Let me ask you, Dominique, because you have all these regional exchanges here in Europe and a lot of people are wondering if in fact later at some point we see a combination of these European exchanges and then perhaps a wrap up and an IPO of that. Is that what you are expecting?

Dominique: Yes. On the returns we signed with ICE that’s what we said. First ICE would acquire the NYSE Euronext group, but later on they would IPO the Euronext part, which is the continental business, and the basic reason for doing that is that we see the derivative market globalizing, accelerating, calling for consolidation in scale and in scope. That’s the core of the deal that we and ICE are doing but we see in the equities market a trend which is not the same — which is rather a rationalization of those markets because everybody tries, the political level the regulators and us, to bring those equities markets closer to the real economy. So it’s kind of a rationalization, and that’s what is suggesting that we should not further globalize and media but rather separate Euronext and bring that closer to the real economy. So we think we will do an IPO — I mean 6-12 months after the closing of the main deal.

Maria: Very interesting because this will create even more shareholder value.

Dominique: Absolutely.


Maria: Let me ask you about the derivatives business. That’s really where the growth is, right? I mean the Liffe business is really the jewel of the business. How is that going?

Dominique: It’s going fine. The markets were somewhat difficult last year. It was across the asset classes we saw the volumes going down around the globe, but indeed the reality is the booming part in terms of value. It’s also where the planet and the participant are accumulating potential risks and vulnerability so there is meetings at stake here in terms of growth — of course meaning consolidation scale-end scope but also risk management and deterring, while the post regulatory is becoming more and more critical. So again that is the core of the deal between ICE and NYSE Euronext — regrouping Ice and the Liffe part of our business, which is the derivative, and create one of the worldwide champions in derivatives equity.

Maria: So far you don’t have a lot of synergies there. I assume you’re not expecting any push back from regulators because we have been down this road before in terms regulators saying this is not going to work. What are you hearing?

Dominique: You are referring to the merger we were trying to achieve with the colleagues there in Germany, Deutsche Börse, at that time. You call that synergy which is what competition will look at. There is no real overlap, just little tiny things, and we think — and we will listen to the competition authorities in the U.S. and Europe — that we don’t have obstacles. But again, we will discuss with them in a professional process.

Maria: In the meantime here we are in the middle of what feels like another bull market. We have been surprised at the sentiment in 2013 and at the end of 2012 in terms of investor behavior. What are you seeing in terms of sentiment in terms of money flows?

Dominique: We see the same trend again. As I said capitol market standpoint 2012 was somehow depressing volumes going down as well but you see the different stressors. Europe in particular is getting much better, more stability, we are not in the same crisis. It’s about combining different measures to re-boost growth and the confidence will come back little by little. Opinion market — one of the key elements is to attract again the investors and this will happen. We are quite confident.

Maria: Are there more opportunities for cost cuts? You have talked about where you see opportunities to slim down. Are you still in that process of looking for further cuts?

Dominique: You are in our group indication?

Maria: Yes.

Dominique: Part of what we said with ICE is that we will generate $450 million synergies over time and part of that are synergies linked to the merger itself. Part of that are the synergies that we were going to execute anyway on our side. $150 million of those 450 comes from our cost catching program and we will continue to execute that. That is normal and business as usual for any company and we do the same.

Maria: I guess people are wondering where do these cuts come from and where are you getting these $450 million in synergies. I understand where the 150 comes from but where is the rest?


Dominique: There is no magic. Part of that 150 will come from the Liffe integration and clearing integration is writing significant synergies. Part of that is what you would do anyway when you are grouping two large corporations because you are overlapping functions and things you have to eliminate and we know how to do that. Part of that as I said is our own rationalization program that started one year ago that we call P14. We are ahead of time and we will continue to do that.

Maria: Dominique it’s good to have you on the program.

Dominique: It’s a pleasure.

Maria: We will be watching the story and we appreciate you joining us today.

Dominique: Thank you.
