So the big drivers going from '16 to '17, probably the first -- the most important item is sales. We had a pretty weak '15, we had a weak Q1, and we had a very strong Q2, 3 and 4. And we have a fairly strong pipeline entering 2017. And so a 20% increase in sales, which obviously will have to get implemented over time, much of those sales get implemented over time, we feel like that is something that is on the shelf and now it's a matter of us getting implemented and having -- making sure the clients and the way we partner with clients gets that done. And we talked about that in Q3, how that actually had a little bit of a negative effect on us because we got delayed. But that's point one. Point two is we have some products that we talked about today, Notifi being one of them, but Notifi and instant issue, CardValet, IPS, some products that we expected would have bigger benefits in '16. And we're seeing some continuing aggregate demand there. And we expect that, that will now start to come online and help us, for better or worse, coming off a lower compare in '16 than we had originally anticipated. We also, as we mentioned, are having some good traction in products like BillMatrix Next and Architect, which were previously not treated as organic revenue growing products because they were in the first year of acquisition, and so we'll get some tailwind from that. A little bit more EMV. Mobiliti will continue to grow. And then probably the last thing I would say is Zelle, right. Zelle is predicted to go live in June. And if it goes live, we'll get some benefit. But the beauty there is it has everyone looking at their retail payment strategies and how they fit. And our -- some of our technologies, like our IPS experience, which is a single-landing idea for account-to-account transfers, bill pay and P2P, we expect things like -- technologies like that to have an impact. We talked about Popmoney Instant transactions I think being up nearly 400% for the year. I think those are the areas that give us some comfort going into '17. And frankly, the thing that could derail us is if something happens in the market where clients freeze up and they're not implementing or they're not moving forward. That is where I see the big risk in our numbers this year.
