Good morning. My name is Marcella, and I will be your conference operator today. I'd like to welcome everyone to the Cullen/Frost third quarter earnings conference call. All lines have been placed on mute to prevent any background noise. After the speakers' remarks, there will be a question and answer session. If you'd like to ask a question during this time, simply press star and the number one on your telephone keypad. If you'd like to withdraw your question, press the pound key. Thank you. Mr. Greg Parker, you may begin your conference.
Thank you, Marcella. This morning's conference call will be led by Phil Green, Chairman and CEO, and Jerry Salinas, Group Executive Vice President and CFO. Before I turn the call over to Phil and Jerry, I need to take a moment to address the safe harbor provisions. Some of the remarks made today will constitute forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995, as amended. We intend such statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, as amended. Please see the last page of the text in this morning's earnings release for additional information about the risk factors associated with these forward-looking statements. If needed, a copy of the release is available at our website by calling the investor relations department at 210-220-5632.
At this time, I'll turn the call over to Phil.
Thank you, Greg. Good morning and thanks for joining us. Today, I'll review third quarter 2017 results for Cullen/Frost, and our Chief Financial Officer, Jerry Salinas, will also provide additional comments before we open it up to your questions. In the third quarter, Cullen/Frost reported $1.41 for diluted common share, and that compared to $1.24 in the same quarter last year and $1.29 in the second quarter of this year. This is a very good quarter for Frost. Besides the excellent earnings, our return on average assets exceeded 1.19%, which is the highest level since the first quarter of 2012, and we also reversed the trend of declining money market deposits and showed strong growth in loans. During the quarter, average loans were $12.6 billion, and this represents an increase of approximately 10% over the third quarter of last year and on a linked quarter annualized basis.
Our provision for loan losses was just under $11 million in the third quarter. It was up from $8.4 million in the second quarter. Although the impact of the Gulf Coast storms to our third quarter results has been pretty nominal, we believe it's prudent to recognize the possibility of lingering impacts in the future. Non-performing assets totaled $150 million in the third quarter. It was an increase from the total of $90.2 million in the second quarter. While our energy portfolio continues to improve significantly, some of these credits are still moving through the snake, as I've said before, towards their final resolution, and we can talk more about them in your questions. Net charge-offs in the third quarter of 2017 were $6.2 million. That compared with $11.9 million in the previous quarter, excuse me, and it was $5 million in the third quarter of 2016.
Annualized net charge-offs represent just 20 basis points of average loans for the third quarter. Overall delinquencies for accruing loans at the end of the third quarter were only 62 basis points of period-end loans. Although this is a slight increase from the 58 basis points in the second quarter, it's still one of the lowest totals in more than two years. Total problem loans, defined as risk grade 10 and higher, many of you know these as criticized, classified, and doubtful loans, OAEM, fell to $705 million, which was a decrease of 15% in the third quarter when compared to the second quarter. This is primarily the result of favorable resolutions like upgrades and pay downs and payoffs.
Finally, outstanding energy loans at the end of the third quarter total $1.39 billion, or 10.9% of total loans. That compares with over 16% at its peak in 2015. Over the past several quarters, Frost has been building on momentum. We've concentrated our focus on steady and sustainable growth. We have an attractive product mix. We're seeing positive responses from customers, and we're also well-positioned for expected increases in interest rates. Average total deposits in the third quarter rose to $25.8 billion. That was up by more than 4% from the $24.7 billion in the third quarter of last year. Deposit growth was aided by our increase in deposit rates on high yield money market accounts and certificates of deposits. Our money market account balances are at their highest level since September 2015, and they've continued to see growth since quarter end.
In consumer banking, we continue to see excellent growth in accounts, customers, and balances. Same-store sales growth for new account origination is up by 13.2% compared to the third quarter of 2016, with strong growth in all regions. 18.8% of our account openings came from our online channel, which includes our Frost Bank mobile app. That maintains our pace of more than double the level of the year before. In the third quarter of 2017, total average consumer loans grew by 10.7% compared to the third quarter of 2016. We're seeing especially good growth in consumer real estate and private banking as we continue to work hard to develop these segments further. We continue to make progress with our mobile and web-based account openings, which help simplify the ways people can build a relationship with Frost.
These digital account openings have helped us grow while applying the same Frost standards that are in place for traditional account openings. On the commercial side, new loan opportunities are up by 18% compared to last year. Our strategy of building our core loan portfolio, which we define as loan relationships $10 million and under in size, continues to help provide steady, sustainable organic growth. New commitments under $10 million were up by 28% in the third quarter compared to last year. They accounted for 53% of the total volume, up from 48% of the total in the second quarter. The efforts that our bankers have been putting into this area are paying off very well. At the same time, we're taking care of our larger customers as well. New commitments at or above $10 million were 42% higher than last year.
Overall, new loan commitments in total are up by 34% from last year. This is the kind of above-average organic growth that we aim for because it helps Frost succeed. Just as importantly, it makes people's lives better and helps our customers succeed. These positive customer experiences are reflected in the recognition we receive from third parties like J.D. Power and the American Banker and Reputation Institute survey, which we continue to build on that success. Just this week, we learned that Frost has been named to Money magazine's list of Best Banks in America, which includes the designation as the best bank in Texas. In particular, I'd like to highlight some results we received recently from Greenwich Associates.
You may recall that in the first quarter, Frost received 33 Greenwich Excellence Awards, more than any other bank nationwide, for providing superior service, advice, and performance to small business and middle-market banking clients. Our performance was already excellent. Late in the third quarter, we got a kind of midterm update from Greenwich. The news was even better. Frost has significantly increased its already high scores in metrics like calls on non-customers. The results show that both large and small company prospects appreciate the way we are building relationships with them as a trusted financial advisor. It's one of our strategic priorities to increase new customer relationships through effective prospecting. The Greenwich scores show that our hard work is paying off. Of course, none of this could happen without our Frost bankers. Besides the outstanding work they do, building long-term relationships that make Frost unique.
During the third quarter, we faced an additional unprecedented challenge in Hurricane Harvey. The storms ripped into the Gulf Coast, affecting not only our banks and our offices in Corpus Christi, Victoria, and the Houston/Galveston area, also damaging the homes and businesses of many of our customers. Yet, despite the evacuations and the damage that our employees incurred at their own homes, they all pulled together very quickly to restock ATMs, to reopen our financial centers, that we could start helping our customers with the rebuilding process. Our eight financial centers in the Corpus Christi region were all open for business the day after the storm passed. In our Houston region, where we shut down all 33 of our financial centers, we were the first big bank to start reopening branches. Within days, we had 31 of the 33 open and serving customers.
Only two of our lobbies had any serious water damage, and only one of these is still being repaired. Everything else in the Houston region has reopened, and we've even opened a 34th site on the East End with our East End Financial Center. Even before they were able to return to their financial centers, Frost bankers were calling on customers to ensure they were okay, to see how we could help. We waived overdraft, NSF, and ATM fees in the affected areas and quickly rolled out a line of commercial and consumer disaster relief loans. The spirit of Frost employees and their dedication to their communities, their customers, and each other is truly inspiring. I'm proud of the way our company responded to this situation. I'd like to thank everyone at Frost for all their hard work and dedication as we look ahead to further growth and accomplishments.
Now I'll turn the call over to our Chief Financial Officer, Jerry Salinas, for some additional comments.
Thank you, Phil. I'll make a few general comments about the Texas economy before I provide some additional information about our financial performance for the quarter. Regarding the economy Despite the impact from Hurricane Harvey in the third quarter, the Texas economy continues to expand with consistent growth and historically low unemployment. The Dallas Fed estimates the short-term job loss in the Gulf Coast in the range of 55,000 to 75,000 jobs, with a quick bounce back this quarter. Rebuilding efforts are expected to create jobs and boost infrastructure spending. Year-to-date, Texas employment is up an annualized 2.2%. The Texas unemployment rate in September was 4%, the lowest in nearly 17 years, and down sharply from 5% at the end of the first quarter and 4.6% at the end of the second quarter. Texas unemployment at 4% is now below the national unemployment rate of 4.2%.
Despite Hurricane Harvey, the Dallas Fed still maintains its 2.6% job growth projection for Texas in 2017. Looking at individual markets, the Dallas-Fort Worth economy strengthened in September. According to the Dallas Fed, the DFW jobs grew an annualized 4.7% last month and 2.6% in the third quarter. The Dallas Fed reports that Metroplex job growth was broad-based across major sectors with construction and mining leading the way. The Metroplex labor market remains tight. September unemployment in Dallas fell to 3.5%, while the Fort Worth unemployment rate declined to 4.2%. The Austin economy expanded rapidly in September. According to the Dallas Fed, jobs in Austin grew 3% annualized in the third quarter. Growth was broad-based with construction, financial activities, healthcare, and wholesale trade accelerating significantly compared to the first half of the year.
Austin's unemployment rate was 2.7% in September, the lowest in nearly 17 years, and significantly lower than state and national levels. The San Antonio economy is accelerating. Jobs grew an annualized 4.5% for the third quarter. Expansion was strongest in leisure and hospitality, manufacturing, mining, healthcare, and government. San Antonio's September unemployment rate declined to 3.9%. The economic report for Houston is in flux as the area recovers from Hurricane Harvey. Damaged homes, general wealth destruction, and family disruptions led to an initial surge in jobless claims. The Dallas Fed reports that Houston payrolls contracted at an annualized 8.9% rate in September following the hurricane. Sectors showed mixed results. Energy sector jobs grew an annualized 24.9% in the month, while leisure and hospitality jobs declined 15.2%. From December 2016 through August 2017, prior to the storm, Houston employment grew by 2.1%.
Growth was strongest in education and health services, leisure and hospitality, and manufacturing. Houston's unemployment rate fell to 4.8% in September. While the economic impact of Harvey was significant, the local economy is expected to rebound fairly quickly. As a result, the Dallas Fed reaffirmed its 2.6% job growth projection for Texas in 2017. Moving to our financial performance. Included in our quarterly results are a couple of unusual items that I wanted to point out. First, during the quarter, the company corrected an over-accrual of income taxes that resulted from incorrectly classifying certain tax-exempt loans as taxable for federal income tax purposes since 2013. As a result, we recognized a tax benefit totaling $3.7 million in the quarter, which resulted from reclassifying the related interest income from taxable to tax-exempt.
Late in the third quarter, we sold $750 million in available for sale Treasury securities with a rate of 1.3% and recognized a loss of $4.9 million, or $3.2 million after tax. The proceeds from the sale of those securities were included in our balances at the Fed at the end of the quarter and provide us with additional investment flexibility in a projected higher rate environment. Looking at our net interest margin. Our net interest margin for the third quarter was 3.73%, up three basis points from the 3.7% reported last quarter. Adjusting out the impact from the correction of the tax-exempt income issue I just mentioned, the net interest margin would have been flat with last quarter at 3.70%.
Higher yields on both our loan portfolio and balances kept at the Fed contributed to about a six basis point improvement, which was offset by the impact of higher deposit rates compared to last quarter. The taxable equivalent loan yield for the quarter was 4.46%, up 14 basis points from the second quarter. Adjusting out the impact from the correction of the tax-exempt income issue, the adjusted loan yield would be 4.42%, up 10 basis points from last quarter. Looking at our investment portfolio, the total investment portfolio averaged $12.3 billion during the third quarter, down about $59 million from the second quarter average of $12.4 billion. The taxable equivalent yield on the investment portfolio was 3.94%, up one basis point from 3.93% for the previous quarter, and was impacted by a higher proportion of higher yielding municipal securities.
The taxable equivalent yield on our muni portfolio was 5.34%, down four basis points from the prior quarter. During the quarter, we purchased about $250 million in municipal securities with a TE yield of about 4.46% with a 21-year average maturity. These purchases offset the $212 million in municipal securities that were called as expected during the third quarter, contributing to the drop in the TE yield from the prior quarter. Our municipal portfolio averaged about $7.4 billion during the third quarter, up about $76 million from the previous quarter. At the end of the third quarter, about 68% of the municipal portfolio was pre-refunded or PSF insured. The duration of the investment portfolio at the end of the quarter was 4.8 years, down slightly from 4.9 years for the previous quarter.
Regarding income taxes, the effective tax rate for the quarter was 9.60%, excluding the tax benefit relating to misclassifying certain tax-exempt interest income that I've mentioned previously, the effective tax rate for the quarter would've been about 13.2%. Regarding capital, our capital levels remain strong with our common equity Tier 1 ratio at 12.38% at the end of September. During the third quarter, we started and completed our $100 million stock buyback program, which was authorized last year. We bought back about 1.1 million shares at an average price of $88.11. Yesterday, our board authorized a new $150 million stock buyback program. Regarding full year 2017 earnings, we currently believe that the current full year mean of analyst estimates of $5.23 is too low. With that, I'll now turn the call back over to Phil for questions.
Thank you, Jerry. I'll open up the call for questions.
At this time, I'd like to remind everyone, in order to ask a question, please press star then the number 1 on your telephone keypad. Your first question comes from the line of Michael Rose. Your line is open.
Hey, good morning, thanks for taking my questions. At the outset, you mentioned that the momentum in deposits had continued. Can you talk about specifically maybe where some of that growth is coming from, and are you starting to see some inflows in deposits in the hurricane-impacted markets?
I'll let Jerry speak to some of the deposit flows. I can tell you that we really haven't seen any Hurricane Harvey deposit money come in at this point.
Yeah, Michael, if we look at a linked quarter basis on a period end, deposits increased 3.1% or 12.3% annualized. A lot of that growth is coming from the high yield MMAs, where we talked about increasing those rates. We're also seeing good increase in our checking account in DDA and IOC.
Okay, that's helpful. Just wanted to talk about the loan growth. Was that impacted at all by the hurricane? You mentioned that the commitments were up pretty substantially year-over-year, and you previously guided to kind of a high single-digit growth rate. Does that still hold? Where are you seeing maybe by geography the strongest growth?
We really haven't seen anything that's significant regarding the hurricane. I think there were $3.3 million of disaster loans through a disaster loan program that we put in place that we have decisioned at this point. That's very minimal. No, I don't think the hurricane's impacting our loan volumes at all. We're seeing good growth really throughout all the regions. A little bit of weakness in the far South Texas markets, but those aren't large markets for us. Loan growth just continues to be positive. It continues to be diversified, and it's across a broad base. We'll have to see what impact the hurricane might have on specific markets like the ones in the affected areas. We're not seeing a tremendous increase right now, but you could see some slowing there. We're going to keep an eye on our pipeline.
I think really what we've seen in the pipeline this quarter, which is down a little bit on a linked quarter basis, but in talking with all our people, I think that's more us just being successful in a number of deals and just in the process of reloading there.
Okay, finally, good to see the new stock buybacks. Given where the stock's trading now relative to where it was last quarter, how aggressive would you expect to be? Capital levels are still pretty strong here. Thanks.
Thank you. The program that we put in place that the board approved yesterday isn't really to be aggressive per se. It's really just good corporate housekeeping. You need a program like that, in our view, for whenever opportunities arise, either you can't use the capital or you think that there's a, as I really believe was the case in this last quarter, there was sort of a dislocation between what management believed about our situation was and what some of the market believed about what our situation was. We say in Texas, that's what makes horse races. We decided to bet on the company to the tune of about $100 million. That was more aggressive than we would typically be.
The program that we put in place now, as Jerry said, is a two-year program, and as we see opportunity to use it, if it's prudent to use it, we'll use it.
That's very clear. Thanks for taking my questions.
Your next question comes from the line of Dave Rochester from Deutsche Bank. Your line is open.
Hey, good morning, guys.
Good morning.
Hey, you mentioned the sale of treasuries at quarter end. Have you guys used the proceeds to purchase other securities in 4Q? I know you mentioned the muni purchases in 3Q, but any additional ones that we should think about, and what were the yields on those?
Dave, our plan is to invest about $400 million of that amount. Our plan would be to try to purchase those as quickly as we can. A lot of it's going to be, of course, determined by what's available in the market. That's the current plan.
The $400 million, will that primarily go into munis as well or other things?
Yeah. Right now it's primarily we're thinking that the $400 million would go into munis. The $350 million we're talking about keeping in balances at the Fed. Gives us more flexibility in this rising rate environment and helps us from an asset sensitivity standpoint. That's the current thoughts.
Yep. Okay. Can you just talk about the increase in the non-accrual loans this quarter? Maybe just some details around product types impacted, reserve coverage, that kind of thing.
Yeah. The increase in the non-performers really is not indicative of the overall portfolio's continued improvement. If you look in the quarter, resolutions exceeded downgrades in the portfolio by more than 2 to 1. If you look at the quarterly additions that we had, say, last year to problem loans, which again, are this risk grade 10 and higher, just our term for, they averaged $380 million. This year it's averaged $153 million, and third quarter is only $100 million. Things are going very well there, and it's going well in the energy portfolio as well. As I've said for the last several quarters, we still have some credits that, as I say, are moving through the snake. These are credits that had property sets that weren't in favor.
Like you've seen some of the activity in the Permian Basin, for example, that maybe have high cost structures, things like that. They're just going to have to work their way through it. They didn't have the opportunity to deleverage like some of our other customers did. The biggest one of these was a $43 million credit, which was a potential problem before it had been servicing its debt. It let the bank group know in the last quarter that it would stop doing that and that it needed a plan to move forward. What we did. And they're a great group of people, don't get the wrong idea. We took a specific allocation which would move this credit down to its liquidation value if we chose to do that. That's in place right now.
It's neutralized as far as any meaningful financial effect where we are right now. I think the good news about that particular credit is that the nature of that their business is enhancing existing production, and so if they're provided with additional capital, they can pretty efficiently increase the amount of production associated with investing that capital in terms of what they do. You know what they do is, again, it's enhancing existing production. They could pretty efficiently increase their production against the loan balance that would be outstanding. It's just a question of do they and how they go about getting that additional capital to do that. Even though it's a big number, I feel we've neutralized the impact in terms of where it is right now versus market value. They've still got an opportunity to make this work.
Was most of this migration related to energy or credits in energy heavy areas?
Say that one more time.
Was most of the migration you saw to NPA, either energy credits or credits that are located within energy dominated areas?
Oh, I see what you're saying. Yeah. Yeah, they were. There was another credit that was about $13 million credit that went non-performer. It's actually recently is demonstrating positive cash flow, and I feel good about the prospects for that one. The other one was in, as you say, in an area that's dependent or heavily related to energy, but it's more in the maritime business, and it has some issues with regard to competition and overcapacity. That's really just a banking business issue. Those things come up every now and then. They're just having to work through some issues, and we'll see how that goes. That one wasn't really one of these credits moving through the snake that I talk about.
Right. Okay. Appreciate the color there. Just one quick one on expenses. The other expense line was down a lot this quarter. Can you just talk about the drivers there and then your outlook overall on expenses for 4Q?
Yeah, they were low. I think what I'd say is typically the third quarter is lighter on some things like advertising, for example. We'll see some pickup there in the fourth quarter. Also, the fourth quarter will be higher a lot of times on the incentive pay areas. We'll kind of finalize those in Q4. Typically, salaries are higher there. Yeah, I think the way I'd look at it is that the third quarter would need to be adjusted up on a more fourth quarter on a normalized basis. I'd go back and look at our historical trends. You can kind of see an uptick there.
Okay. All right, great. Thanks, guys.
Thank you.
Your next question comes from the line of Steven Alexopoulos from JPMorgan. Your line is open.
Hi, everybody.
Morning.
Morning.
I wanted to start on the $43 million non-performer that you saw this quarter. I assume that was E&P. Is that correct?
Yes. Mm-hmm.
Was that a shared national credit also?
Yes.
Okay. I just want to understand, I would think there would be less pressure on E&P at this stage, given oil's over $50. What would cause a loan that size to trip into non-performer at this stage?
Well, the fact that they informed the group that they were not going to be making interest payments.
Oh, okay. Got you. Thank you. What were the thoughts? I know you sold a pretty significant chunk of Treasury securities in the quarter, $750 million, and you took that $3 million loss. What was the thought behind that? I want to fully understand that.
Well, sure. If you think about it, we were only earning 1.3, just five basis points of what we would earn at the Fed. They just thought there was an opportunity to utilize some of those proceeds in this higher rate environment.
Got you.
Also, as Jerry I think mentioned before, too, we're only reinvesting a part of it.
Right.
We're letting some of that ride in liquidity. That'll help our asset sensitivity. That's just sort of our orientation in terms of what we see, we believe is happening with rates. We'll keep some dry powder in that.
Got you. I appreciate the commentary on the expenses and the pickup. If we look, it's a movement too in the fee revenue this quarter. Looked a little bit high. How do you think about a run rate of fee revenue from where we came out in the third quarter?
Give me just a sec. Yeah, I think that, looking at the fees, I think that I would expect that it's a fairly good run rate. Typically in the fourth quarter, if you go back and look at some of our historical performance, insurance revenues are typically up in that fourth quarter. I expect we'd probably see that sort of trend. Other than that, I think it's a fairly good trend, of course, ignoring the loss on the securities transactions.
Got you. Okay. Thanks. Just one final one. With all the deposit growth you guys are seeing in the money market account now that you've raised rates there, how do we think about margin here in the fourth quarter? Is that going to continue to pressure margin?
The way I tend to look at it is kind of flattish with what the adjusted 3.7 that I mentioned. We took this $373 for the actual, adjust out the adjustment, we're at $370. I tend to look at it as staying pretty flattish. The challenge there, of course, is going to be the timing of the purchases of the municipal securities that we talked about, the $400 million. As you mentioned, of course, also the deposit level. There may be a little bit of pressure on the percentage itself that may be more optics than anything else. Where you'd see with we'd love to get more deposits, we could potentially see a little bit of pressure on the percentage, but an increase in net interest income dollars.
Terrific. Thanks for taking my questions.
Sure.
Thank you.
Your next question comes from the line of John Pancari from Evercore ISI. Your line is open.
Morning.
Morning.
Regarding the energy book, again, with that credit, can you just remind me the size of the reserve, still around 4.5% of the energy book?
No, with time that has gone down as it has improved.
Yeah, we're down. Last quarter, we were at $385, and we're down to $374 this quarter.
Okay. All right. At that $374 level, still comfortable that it's adequate to absorb the remaining items that can move through the snake here? These are somewhat lumpy in terms of the size of these credits. If we've got a few more, you're going to be hitting that reserve by a fair amount. Just curious how it stands. Thanks.
First of all, answer your question is yes. As far as what hits the reserve is going to depend upon, obviously, whatever happens, what they're able to do. I want to keep in mind that just the overall portfolio in the energy sector has really been improving. You've got a dichotomy here of these firms that weren't able to deleverage, if you will. I'd say another thing is that we haven't identified any new credits in the energy side this year. Again, like I said, that makes horse races, right? That's what makes it. We feel like we're doing a good job of recognizing where we are with these credits, and when we see issues or see something get worse, we're aggressive in marking it to where it needs to be. I'm not worried about the remaining credits in the snake.
It'll be what they are, but I frankly moved on from that.
Okay. All right. Back to the margin. On the deposit side, can you just remind us of the deposit beta that you assume in terms of this cycle and where you stand currently?
We do have an assumption for a Fed hike in December. It's not having a material impact, of course, on our numbers. Our betas, I guess, the way we look at them is that when we made those deposit increases in July, we kind of looked back over the Fed had raised by that point 100 basis points. We probably took a beta at that point of, say, about 30%. We would expect, as rates go up, we'll just need to look at the competition. We kind of feel like we're in a good place, to be quite honest with you, compared to some of the competitors out there who haven't raised rates. Our betas may not need to be as aggressive going forward, but we'll just have to see how it plays out.
Okay, the incremental beta may not be as high as that 30?
Correct. We'll just have to see what's happening in the market.
Yeah, John, I think we did the heavy lifting last quarter, right? Now what we're doing is we're going to keep an eye on the market. We want deposits to grow. We want to make sure our value propositions is good enough to attract customers. I think it'll be a little bit more fine-tuning than it was with the heavy lifting we had to do last quarter.
Okay, thanks, Phil. Lastly, back to the capital discussion regarding the buyback. Just trying to gauge how you're thinking about the magnitude. What's the likelihood that you remain somewhat aggressive with this program and potentially follow it up with another one? Your capital levels are still relatively solid. I know that this was already asked about your appetite from here, is there a rationale when you look at your growth outlook right now, is there any type of rationale where you can stay somewhat aggressive in terms of buying back here and just given how solid your capital levels are?
John, I'd say that it's going to depend on growth prospects, right? We're a highly rated company. We've sort of managed now to increase our loans in a sustainable way. A lot of that is related to, again, this focus on the core part of the portfolio. It's really well diversified. Like to use capital in that regard, I'd like to have a strong capital position. That said, we'll use the buyback in an opportunistic way if we feel it's warranted. When you look at the buybacks historically, I think the $100 million that we've sort of authorized has been fairly close to what I'll call the leakage is in terms of the stock that goes out based upon stock plans that the company has and that kind of thing. This one really represents sort of that level plus a little extra.
It's a little bit bigger than what we had before. I wouldn't read too much into strategy with that program. It's really just to give management the ability to take advantage of situations in favor of shareholders as we see it. Look, again, I hope growth is what uses this capital up. We're committed to sustainable organic growth. If it doesn't, we have excess capital just like we've done over time, we'll continue to use buyback, the board meets every quarter.
Got it. All right, thanks, Phil.
You bet.
Your next question comes from the line of Ebrahim Poonawala from Bank of America. Your line is open.
Good morning, guys.
Good morning.
I'm sorry if I missed this. Did you say what the money market rate was this quarter and whether that reflected the full impact of the upward pricing on those deposits?
Maybe the best way that I could answer that is looking at our deposit costs on interest-bearing deposits. They went up from six basis points in the second quarter to 15 in the third quarter. If you recall, that rate hike went in, I guess, about the 24th of July. We'll still have a little bit of an impact in the fourth quarter.
I know you mentioned that the money market high yield growth was strong. Is it at a point where you believe it's okay that even if we get a December rate hike, you don't need to further increase that rate? How do you sort of look at the competitive pressures in the market, and do you expect that we might be in a situation where you need to raise that again if the Fed moves in December?
Ebrahim, we'll just look at it at the time. Like I said, I think we'll fine-tune it. I think we'll increase. If the Fed increases, I think we'll increase. I don't think we'll increase the same level. I think our high yield rates like 35 basis points on the high end, which is a great rate.
Seventy-five.
Yeah, 75, 80.
70, 80.
It was probably less. CDs really aren't that big a deal, in terms of their dollar impact on our balance sheet and the marginal effect. Just since you asked, I think probably the pressure on, if I can use that word, on betas for CDs is less than MMA. I think you're going to have to make sure that your MMA continues to be a relevant rate. I think we'll see increase. Don't think we'll see anywhere near the 35 basis points or moving to the 35 basis points that you saw last time. Jerry's got that in his projections that he just talked about too.
Understood. I'm sorry if I missed it, you mentioned there was a spread between the 373 and the 370 margin. What was the three basis points?
I mentioned in my comments that we did have a correction on some loans that were misclassified as taxable rather than tax-exempt. We tried to take that impact that was related to 2017 out of the margin just to give a more normalized rate, which would've been that 370.
Just one last question, Phil. In terms of when you think about balance sheet growth, I think it was earlier asked, did you see any dampening impact in this quarter from the hurricanes? If not, do you expect that the kind of quarter we saw, about 1.5%-2% sequential loan growth, that's sustainable as we think about 2018?
Yeah, I'd like to see similar loan growth. We said high single digits is what we'd like to shoot for, we're going to have a goal to do that. We really haven't seen much impact from the hurricane with regard to deposits or loans. We're going to have to keep an eye on it, right? Because you just don't know, we haven't been through it. So we're going to have to see the impact. It might be in the fourth quarter, early first. I'm optimistic about it. We want to be careful and prudent about it, but I'm optimistic about how we're able to grow and what our people really have been able to do.
Understood. That's all I have. Thank you.
Thank you.
Your next question comes from the line of Jennifer Demba from SunTrust. Your line is open.
Thank you. Is there any way to quantify the fees you lost during the quarter from the waivers related to the storms?
Well, yes there is. It has been done. It's mainly about remembering it.
Yeah.
Seem to recall it was around a quarter of a million dollar.
Yeah, I think at the high end, Phil. I really don't remember. I thought it was $200,000.
Okay. Something in that range, Jennifer.
Okay. Thank you very much.
Thank you.
If you'd like to ask a question, please press star and the number 1 on your telephone keypad. Your next question comes from the line of Brady Gailey from KBW. Your line is open.
Hey, guys, it's Brady. Good morning.
Hey, Brady. How you doing?
I knew it, Brady.
Yeah. Not Brady. One more question on fee income. If you look at one of the big drivers for increased fee income on a linked quarter basis, it was also in that other category, went from about $7 million to roughly $11 million, a little under $11 million. What were some of the components that pushed up other fees?
Sure. One of the things there in that other income category was we did get $1.2 million related to a recovery. This was an asset that Western National Bank, our acquisition that we did in 2014. They'd written it off, so on our books it had a zero value, and we got $1.2 million related to that in the third quarter. We also had a real strong quarter on derivatives activity. They were up about $900,000 compared to the third quarter last year. If you'll recall, we sold this Frost Bank tower in downtown San Antonio and recognized a gain, we deferred a portion of that gain because we're still in the building. That gets amortized into income, about $700,000 a quarter, and we didn't have that in the third quarter last year. That building sale occurred late in the fourth quarter last year.
That $700,000 a quarter, how long will that last?
That should go on until mid-2019.
All right. Just to be clear, back to Hurricane Harvey, it sounds like you all did not take a Hurricane Harvey specific provision. Is that the right way to think about it?
Yeah, it is. Just the way the reserve works and how it's calculated, and improvements in other parts of the portfolio, and just our ability to look on a macro basis. There was no specific allocation or specific provision for Hurricane Harvey, we really feel good about the general allocations that we have, which would recognize that along with lots of other things that are out there in the environment. Feel good about where we stand with regards to having a reserve against what might happen there.
All right. Lastly for me, if you look over the last three years or so, I think you might have even said it in your comments, Phil, energy has gone from over 16% of loans to a little under 11% of loans. Now since we've seen some stability with oil over $50, do you think now is the time right to think about starting to increase that percentage? Could that be additive to loan growth for you guys over the next couple of years?
Brady, I wouldn't increase the percentage just strictly to add to loan growth. What I expect from the business is for it to continue to grow and to grow in line with what the rest of our loan portfolio and our loan business does. If you look at what's going on in the markets today, based upon what we're hearing from our people, it's slowed a little bit on energy, and it may be because CapEx budgets near the end of the year fill up. There's been a little bit of slowing on these big acreage deals that have been pretty public out there. I think on a long-term basis, the independent producer is an important customer to us, and they may not be coming back until oil gets to $60 in any great degree. I don't think it's really a robust market right now in energy.
It's steady, but with a little bit of slowing in the pipeline. I would not look for that part of the portfolio to sort of make our dreams come true in any way. It'll be a part of that, but I look to it more being in line with what our growth. We may be more in line with sort of where we are right now. As a percentage, it could move up a little bit on a quarter or go down occasionally. In the Permian, even though the independents may take, say, 60 to work, 52 works well in the Permian and in the SCOOP. Beyond that, it can be problematic.
Thanks for the color, Phil.
You bet.
Your next question comes from the line of Ebrahim Poonawala from Bank of America. Your line is open.
Hello?
Ebrahim?
Ebrahim Poonawala, your line is open.
Hey, guys. Can you hear me?
We can now.
Sorry about that. Just a quick question. Did you say what you expect the effective tax rate to be going forward and into 2018?
Well, we don't give any guidance yet on 2018. If I was looking at the fourth quarter, I'd probably say our expectations would be that we'd be somewhere in that 13%-14% range.
Appreciate that you don't want to give the 2018 guidance. Would the delta from the 13-14 versus into 2018 would be just the level of muni purchases, or are there other things that would impact the tax rate?
Of course, the strength of earnings because from that marginal level.
Yep.
That corporate rate is still 35%. Yeah, it could be affected by a lot of issues associated with that.
Got it. That's all I had. Thank you.
Thank you.
Your next question comes from the line of Matt Olney from Stephens Inc. Your line is open.
Hey, good morning, guys. Thanks for taking my question. Just want to ask on the update for the shared national credit portfolio, do you guys have the updated balance of that portfolio? Were there any grade changes from the recent national exam, for the SNCs recently? Thanks.
Yeah. The size of the portfolio, if you just give me a second. Period end was $795 million, and there was no change as a result of that last exam.
Thank you.
There are no further questions at this time. I turn the call over to Phil Green.
Okay, everyone. We thank you for your participation in the call. We'll be adjourned.
This concludes today's conference call. You may now disconnect.
