Well, remember, I think, we, I mean, it was in one of the footnotes, we just re-classed one of our, just for you guys to make sure you understood, we re-classed one of our divisions from rate to FX. So, there wasn't a consequential change to it, it was just from how we look at our business, we put a finer point to it and shifted it, but it didn't change the business or the models or the gross revenue or anything. It was just a categorization model. With respect to foreign exchange, two things are going on. One, the business topics are just creating huge volume. All of the press about the euro, the Eurozone currencies and about their countries, IMF, the euro bailouts, the paper today talking about they have to do way more than the $700 billion that the U.S. did. I mean, all of these things create volatility, expectation of issuance, movement and are therefore volumes in our business. I mean, they are the things that drive our company's growth rates and volumes. So these structural things really are extraordinary out there. The issuance levels, we can't imagine how they could go away now. They have such vast deficits everywhere in the world. Bailouts create ever more issuance. So, structurally, I think the business is set up for the long, long run to be spectacularly large. With respect to the narrow portion, we do a substantial amount of our business in Europe and we do earn quite a bit of our profits in euro and pounds and as the dollar has rallied dramatically against the euro, on a constant currency basis our business is doing spectacularly, but when we presented in dollars it does restrained slightly how we look. So, our guidance was restrained to the $320 to $340 million simply because you've seen the euro, right weaken against the dollar. And we make lots of money in euro as we do, we have a spectacular Greek franchise and doing the business, when Greece is on the cover of the newspaper every day, it's really good for our Greek brokers. They are very happy.
