Thank you. Our next question is from Bryan Keane of Deutsche Bank. You may begin.
Bryan Keane, Managing Director in Equity Research, Deutsche Bank
Hi guys. Can you hear me alright?
Jeffrey S. Sloan
Yeah.
Cameron M. Bready
Yeah.
Bryan Keane
I just wanted to follow up on that international margin growth because that was the real surprise in the quarter.
I’m just trying to figure out, was that all mostly due to Spain? And then when you get pricing like that, like you’re getting in Spain, how sustainable is that when we look into next year or does that get competed away?
Cameron M. Bready
Bryan, it’s Cameron, I’ll jump in and I’ll ask Jeff to add any additional color. Let me just step back for a second and note some of the drivers for the international performance that we touched on in our prepared remarks. First of all, Spain obviously is an important driver but again recognize a good portion of that is execution, as Jeff mentioned. With double-digit transaction and volume growth, notwithstanding the nice tailwind we’re seeing from the lower interchange, we’re clearly pleased with the execution in the Spanish market. The rest of the international businesses in Europe continue to perform well also but for Russia, which we talked about which continues to be a bit of a headwind for that business.
In Asia, you had organic revenue growth of 9% which accelerated quarter-over-quarter year-over-year which is obviously contributing to the margin performance for the international segment as well. You couple that with the addition of Ezidebit which contributed 12 percentage growth per points to growth on a revenue basis, you’re obviously driving operating income and margin expansion as well given that Ezidebit’s coming in at a higher margin than our average. So when you roll all those pieces together, I would say a lot of it is execution and performance, the addition of Ezidebit, and naturally the regulatory changes in Spain are helpful, but I think a lot more about is it is the execution we’re seeing in the business.
David E. Mangum
Bryan this is David. In terms of the tail on something like the interchange reductions, what we typically see and what we assume certainly now in the case of Spain is that will dissipate over time. If you think back to the Durbin days here in the United States which is just going back a couple years ago, you had a year, maybe a little less than a year, of benefit from changes in the regs as well as the interchange. Remember though, that was a steadily decreasing benefit as time went on. So it’s a really nice benefit right now. It will decrease over time. I would say this, though.
I think what’s really tell tale about Spain — setting aside interchange for a moment — is the volume growth and the transaction growth that Jeff mentioned a little while ago. 13% transaction growth this quarter, double-digit volume growth, implied or implicit, in that double-digit revenue growth as well. Similar metrics in Q1, similar metrics we expect for the rest of the year. It’s when you combine that with this interchange benefit that you really get the outstanding performance and then feeds the list of items that Cameron just went through in terms of overall international margins.
Bryan Keane
Okay and I assume you’re taking share in Spain to get those kind of transaction growth rates and then finally, just Cameron, on operating margins international, what does the back half guidance then imply for that? What should we put in our models or expect?
Cameron M. Bready
Bryan, we absolutely are taking share in Spain. We are, remember this, that what’s really interesting about that we are the largest provider in Spain. We have the largest market share: 25%, 28% depending who’s counting. But certainly with growth rates like that we are absolutely taking share and we’re very happy with performance in Spain.
Jeffrey S. Sloan
Yeah and then Bryan on your last question, I think we would expect a little bit of margin degradation relative to what we saw in Q2 for the international business in the back half of the year, as David highlighted with some of the benefit from the interchange reduction in Spain beginning to dissipate, you’ll see a little pressure on that relative to what we just reported. But obviously, we’re still for the full year guiding toward margin expansion for the international segments, as well as the North American segment and the total company in totality.
Bryan Keane
Okay, congrats on the results.
Cameron M. Bready
Thanks Bryan.
Jeffrey S. Sloan
Thanks Bryan.

Thank you. Our next question comes from Tien-tsin Huang of JPMorgan. You may begin.
Tien-tsin Huang, Senior Analyst, JPMorgan Chase & Co.
Great, thanks. Good results here. I just wanted to get some clarity on what’s driving the guidance raise. I caught the JV, the Comerica push out and migration. Obviously had some upside here, but can you be more specific?
Jeffrey S. Sloan
Sure, I’ll just add something Tien-tsin and Cameron can comment on the financial modeling around the guidance.
There’s no impact in the guidance as we said back in July as it relates to Comerica which is material…
Tien-tsin Huang
Okay.
