Video message from NYSE Euronext CEO Duncan Niederauer to employees

Good morning everybody.  It’s a Friday morning in New York and I just wanted to give everyone an update on what has been another eventful week; it seems like every week’s an eventful week now.

Three topics this morning:  One, is to give you an update on the statement of objections we just received from the case team and where we go from here.  Number two, how we’re doing on the immigration process.  And number three, a few words consistent with what I said in the employee note about the macro environment and its impact on the stock price.

So first topic is, we did get the long-awaited statement of objections a couple of days ago.  It is a 100-plus-page document, we’re still working through it, I hope to have a summary by the end of today, and the way the process will work now is we have two weeks to respond to that statement of objections.  Now what I’ve been saying to a lot of folks is remember, it’s called a statement of objections for a reason.  This was not a surprise to us, this was an expected part of the process and what this does it is it narrows the funnel so we now know what the case team in Brussels, who’s been dedicated to the merger proposal, thinks about the deal.  And what this document articulates is the issues and concerns that they still have with the deal.  So the good news is anything not mentioned in the statement means they’re satisfied that if we put the two companies together, there’s no issue with those parts of the business.

So we will spend the next two weeks responding to that.  We are likely to request an open hearing and attend that in late October, and then I think we’ll know where we stand a lot more by the end of this month.  So that’s how things will play out for the next few weeks.  But again, no surprises.  Some of the headlines said that the EU objected to the deal; this is just a natural part of the process that will play out over the next two to three months.

Secondly, on the integration, we continue to make good progress.  I thought Andrew put it very well the other day when he said we are probably six to nine months ahead of where we were with the NYSE-Euronext combination.  So I know for those of you who are working on it there are times when it’s challenging, there are times when it seems quite tedious.  Just stay the course, and before you get frustrated with anything just kick it up to us and we’ll do the best we can.  Senior management from both companies is talking on an almost daily basis, and I will promise you we can resolve any issues that we’re having and we’re very close to making some key decisions and I think the spirit at the senior level continues to be quite good; we just need to make sure that spirit cascades down at both companies.  But we are well ahead of schedule and I’m very proud of what everyone’s been working on there.

Lastly, in terms of the day-to-day business, we just put out our third-quarter volume numbers today.  You saw them, all very, very strong.  I think, you know, if you compare that to previous summer quarters, it was quite a strong quarter.  So I won’t preview the third-quarter results for you – we’ll get to that at the end of the month when we do the earnings – but I think you could see from the volume numbers a very solid quarter.  So thanks to all of you for keeping your heads down and staying focused on the business; that’s what we need you to do for the balance of the year, and assume I will record videos like this – probably every week for the next few weeks here as the regulatory process unfolds in Brussels.

Just a few words on the macro environment.  As I said in the employee note, there’s not much we can do about it.  You’ve got EU sovereign issues, you’ve got a weakening Euro, you’ve got ongoing concerns about a financial transactions tax or where European regulation might go.  We will keep you all apprised of all that, but understand that most of that is out of our control.  We just have to focus on what we can control, and I think all of you have been doing a great job at doing that.

Lastly, just a quick preview on my travel schedule.  It looks like I will be in Amsterdam next Wednesday and then Brussels next Thursday and then back here for some meetings at the end of the week.  And then most of the week of the 24th will have me in Europe, probably starting in Brussels, moving to Paris for our board meeting and then heading to Russia for some meetings that I have with the International Advisory Committee at the end of the month.

So look for more of these in the coming days and weeks.  Thank you for your support and have a terrific weekend.  See you out there.
