Well, first of all, I will tell you that as I look at the activity levels that we had in the fourth quarter, they were substantially elevated. It was a very strong quarter of production, and it was across all of our corporate banking verticals, it was across nearly all of our geographies. If the tax policy changes, beginning to come into play, I frankly -- I had a lot of conversation with a number of CEOs and CFOs, middle market corporate relationships over the last few days, and various -- unquestionably a growing optimism, that can create a tailwind I believe for us as we look at 20018. But I'd also remind you that we've continued to reallocate our resources. We've, consistent with our North Star strategy, have built out new verticals, our TMT vertical continues to frankly accelerate, and we are developing a very strong name there. Our healthcare vertical had a great quarter. I think they were well positioned for 2018. The ACA Act, with that kind of becoming a little bit less of an issue; there is more clarity in that industry. We are very active there, and I think that you will see more around that space in the near future; energy -- with energy prices that's clearly creating a tailwind. And frankly, I'm really pleased we have some leadership, we have recruited additional middle market bankers throughout, some of our footprint, look you know, what we shared in the past around the Floridas and North Carolina, we got Tennessee really moving, Indiana being our strongest region for the year. But some of the markets where we have recruited bankers, we have new leadership such as Georgia, such as Cleveland, Northeast Ohio, such as Chicago, these are markets that frankly had a really good fourth quarter and we believe are very well positioned for 2018. Tayfun shared with you growth in that nominal kind of GDP, I believe that there could be some tailwind there. I'm optimistic we got the right business model, we got great talent and I'm looking forward to again.
