(Harold R. Carpenter, EVP and CFO): Looking forward, and considering the addition of the two new franchises in Memphis and Chattanooga to the mix, we don't have the algebra to speak as confidently about the balance sheet and interest rate position. But our initial assessment remains consistent, in that we consider the additions to be modestly liability-sensitive, and that we believe we have many alternatives available to us to modify those positions fairly quickly without significant sacrifice to either net interest income or net interest margin.

In summary, we obviously expect a meaningful interest in net interest income in the last half of the year due to the addition of CapitalMark and Magna, but we aren't expecting any meaningful dilution to our margins at this point. In fact, our current forecast would reflect fairly stable margins for the remainder of the year.

…

Lastly, we are reporting fees to average assets of approximately 1.24% for the second quarter. With Magna and CapitalMark, we expect some minimal dilution to that metric by only 2 to 4 basis points presently.

…

Our core expense to asset ratio was 2.31% for the same quarter of 2015. As we have stated for many years, the primary strategies to ultimately achieve our long-term expense to asset ratio target of 2.30% is to grow the loan portfolio of this firm with a corresponding increase in operating revenues and earnings. That will also be the strategy we will deploy with CapitalMark and Magna as well.

We expect to see a slight rise in both our expense to average asset ratio and efficiency ratio in the third quarter with the addition of the two new banks, but the rise will be modest at best, perhaps 8 to 10 basis points on our expense to average asset ratio, with our efficiency ratio rising but remaining in the low 50s as of today.

That said, our synergy case for both acquisitions remains in place and will eventually help us create more operating leverage in future quarters as we fully expect to achieve the targeted EPS accretion targets in 2016 that we spoke about on the acquisition conference calls.

…

(M. Terry Turner, President and CEO): Number two, geographic expansion: you know that Chattanooga and Memphis have long been targeted markets for us. They are urban markets, dominated by the same larger regionals with whom we compete in Nashville and Knoxville. We believe those two markets could represent $3 billion to $5 billion of assets for us. We've made our play in both markets, and once both mergers are consummated, we'll be focused on exactly the same approach to organic growth in those markets as we and they have focused on for some time.

David Feaster, Raymond James

Q: Can we talk about costs? You guys have exhibited pretty impressive cost control, and efficiencies continue to improve. Could you maybe just give us your thoughts on your expenses going forward, and maybe what we could expect with the run rate with the acquisitions?

A: (Harold) Yes, David. I'll speak to that in two ways. First of all, with Magna and CapitalMark, we think that from a ratio perspective we'll see some uptick in the expense average ratio and the efficiency ratio, but it won't be significant.

As to the core bank, we don't really expect to see any meaningful increase in other expenses. We'll probably see some increase in ORE expense going into the third quarter. But other than that, we should be fairly stable with respect to all other expenses, other than the compensation line. We expect compensation will increase. We think it will increase ratably over the remainder of the year as these new hires come on board.

Q: Okay. Since we're talking about new hires, could you maybe talk about how the integration is faring, and maybe the contribution from the new hires, and then even the Memphis lift out?

A: (Terry) David, I couldn't quite get all of that question. But if I understand, you want us to comment on how the integration is going, and the progress that we're making with the lift out. Is that it?

Q: Yes, that and the new hires.

A: (Terry) Yes, okay. Well, I would say quickly that we're excited about the progress in both the banks. Let me start with what's going on with them. I think CapitalMark in particular had a whale of a second quarter. And it would appear to us it has really outsized balance sheet growth, and would lead us to believe that our synergy case is -- I would say they are performing at a pace that would indicate that it's probably better than what we assumed as we built our original synergy case.

Magna is also performing better than the budget for balance sheet and earnings growth, which we used in developing our synergy case. So we're excited. I think we commented in the press release specifically that we think it is a great tribute to the folks and in those banks that they're continuing to outperform their original projections at a time that where they're going through a transition.

We've begun integration process. We're holding orientation sessions for all of the associates. I don't know, I'd say we're 35% or 40% of the way through that process. And I think we're building great excitement in both companies.

Andy Stapp, Hilliard Lyons

Q: Okay, yes. And what are your debit card fees -- I don't know if you have this -- including CapitalMark and Magna?

A: (Harold) Do you want the total?

Q: Yes.

A: (Harold) Okay, hold on just a second. This year, so far it's been about $3 million. That's without Magna and CapitalMark.

Q: Right.

A: (Harold) So, we're anticipating, with CapitalMark and Magna, and looking forward the next 2 to 3 years of getting over the $10 billion threshold, that we're looking at probably a $4 million to $5 million hit on debit cards. If that's what you are alluding to.

Tyler Stafford, Stephens

Q: Okay. And then last one for me. Harold, I apologize if I missed this in your prepared remarks. But in outlook or comments on the impact of the pending deals to the margin once we get those closed for 3Q and 4Q?

A: (Harold) Yes, we don't expect any meaningful dilution to the margin at all. Our forecasts would say that the margin stays pretty stable for the rest of the year, with the inclusion of CapitalMark and Magna.

 

Brian Martin, FIG Partners

Q: Harold, can you just talk a little bit about, post the transactions, when the first quarter of a clean expense run rate, when you get some of these cost savings out of it, that based on when the integrations occur and whatnot?

A: (Harold) Yes, we think on the Memphis franchise, their technology conversion is scheduled for mid-November. So you're probably looking at a run rate on expenses starting in January of next year; so, say, first quarter. On CapitalMark, their technology conversion is scheduled for the middle of March, so you're probably not going to see an expense run rate until maybe May or June.

Q: Okay. And then just any update on the capital for the tangible common equity, post-transaction? Still kind of that 8.5% type of range, or is there any thought on any changes there?

A: (Harold) No, I don't think there's any changes. I'm hopeful that we'll be in that 9% -- or closer to that 9% number.

Q: Okay, post-transaction. And then just as far as maybe just additional credit levers, how are you guys thinking about that with the growth and then the additional assets from the two acquisitions?

A: (Harold) Yes, once you apply all the accounting rules, we're probably looking at a reserve somewhere around 105 to 110. That said, we still believe that the core bank has credit leverage left to harvest, at least over the next, say, 1 to 2 years.
