Sure, in terms of remaining relevant, in terms of enabling our clients to get to a more efficient place, I'd call it part of an overall strategy. Certainly the white paper and APTP are very, very closely linked in things that clients can do today in a very meaningful way. When you look at blockchain and you pick things like syndicated loans and foreign FX, let's use those two examples. In the market today, we're not in either of those spaces and they are just horribly inefficient in the clearance of settlement activities. If that can be and it can be, incorporated and built out into a blockchain, I personally see that as the very likely successful execution activities that will happen first. As that happens, I see some of the bigger plays happening. Let's go back to what you said about APTP which was announced three years ago and we're now live in London. We already had a strong technology platform. Accenture certainly knows how to go in there and work with clients. Three years later with the pieces, in essence, already in place and needing fine tuning, we're now live with two very capable operators who execute for a living doing the execution. What I'm trying to point out is transformation, even when all the pieces are in place, is not for the faint of heart and is a pretty tough road to go down. The transformation I have been looking at with blockchain is wildly exciting because of what the technology enables. Building this out to cover all the intricacies that our markets have and the complexity that our markets have is going to be an even tougher road, but the opportunity here is so strong. For Broadridge, to be with our key clients or people who should be our key clients, in these dialogues, where for our clients, it will be clear that if we can get this technology achieved, to integrate it into the books and records that we're running for our clients now, we can make that part work for them, I think makes what we do today more relative for our clients, what we should be doing for the people who aren't our clients more relevant and makes us more relevant in these new dialogues going forward. But what I wanted to point out is APTP was not for the faint of heart and I am really psyched that we're live in London and that Barclays has signed. Many years from now, I expect to be saying the same thing about some blockchain initiatives, but again, nobody should be thinking this is, you know, go to the Apple Store, buy it, download the app and you are off and operating this afternoon. That is not what it will be.
