Alberto J. Paracchini - President, CEO & Director
Thank you, Allyson. Good morning, happy new year, and welcome to our fourth quarter earnings call. As usual, joining me today are Lindsay Corby, our CFO; and Tim Hadro, our Chief Credit Officer. I'll begin with an overview of our performance and key highlights for the quarter, then pass the call over to Lindsay who will give you a detailed overview of our financials. After that, I'll come back and give you closing remarks before opening the call for questions.
Moving over to Slide 3 on our deck. We ended 2018 with a very strong quarter where we had our highest level of earning since becoming a public company in 2017. The increase in our earnings power reflects solid execution on our organic growth strategies as well as the continued benefits from our acquisition of First Evanston. Net income came in at $17.1 million or $0.46 per diluted share, which included an asset impairment charge, certain merger-related and conversion expenses that impacted our earnings by $0.03 per share. Along with our growth and earnings, we saw a steady increase in our level of returns. ROA came in at 139 basis points and ROTCE was 15.49%. Pretax pre-provision ROA was 2.23% in the fourth quarter, an increase from 2.13% last quarter and 1.73% from the year-ago period.
The higher level of earnings was primarily driven by an increase in revenue, which came in at $67.8 million or 6.4% higher than last quarter. Our net interest income was up 1.3% with solid growth in average loan balances, offset by a decline in accretion income this quarter. However, if we exclude accretion income, the core margin expanded nicely, which increased 14 basis points to 4.13%. The quarter was strong in terms of noninterest income growth, which was up 30% from the prior quarter. Our Small Business Capital Group had a good quarter of loan production, which resulted in higher gain on loan sales.
Overall, business development activity was solid with loan originations coming in at $164.9 million, which was anticipated after the very strong levels we experienced in the third quarter. Payoff activity increased, however, which moderated the net growth in the portfolio this quarter.
Loans grew by $45.8 million, or 5.3%, annualized. The loan growth was strongest in the C&I category. Commercial banking team had a particularly good quarter of production and we're pleased with the synergies that we're seeing from our combination. Customer activity in commercial banking was very good during the quarter and the second half of the year. We're seeing customers investing in their business, buying equipment and expanding or modernizing facilities.
Moving over to liabilities. Total deposits were essentially flat growing by $9 million. That said, we had solid inflows of non-interest-bearing demand deposits in the quarter, which increased to 31.8% of our total deposits. This allowed us to be proactive with deposit pricing given the shift in expectations regarding additional rate increases. We've been very pleased with the deposit trends that we have seen in the Evanston market. It's customary to see some runoff after an acquisition, but deposits at the former First Evanston branches were higher at the end of the year than they were at the time of merger. We think this speaks to the quality of the deposit base acquired, the continuity and strength of the team and the approach taken with our integration and customer transition plans. We've also had a positive shift in the mix of those deposits as we've replaced higher cost municipal deposits with lower cost commercial deposits in the market.
With respect to expenses and efficiency, we continue to make strides towards our objectives in this area. Last quarter, our adjusted efficiency ratio improved to just under 55%. On a year-over-year basis, we improved by approximately 8 percentage points and our deposit -- average deposit per branch increased to $63.6 million from $43.6 million, which reflects both positive impact of the transaction and the efficiencies generated from our branch rationalization efforts.
Asset quality improved with NPLs coming down, charge-offs remaining stable and the allowance for loan losses increasing to support loan growth.
Before I pass the call over to Lindsay, I would like to take a moment to talk about the impact that the government shutdown is having on our government-guaranteed lending business. First off, I'll start by saying that we hope our leaders can come together and solve the problem directly impacting over 800,000 employees and a significant number of small businesses throughout the country. The shutdown impacts us primarily in 2 ways. First, it impacts our ability to obtain guarantees on new originations. In anticipation of this shutdown, we secured guarantees on loans we had in our pipeline, but have not been able to secure guarantees for newer underwritings.
Second, the shutdown also impacts our ability to sell loans in the secondary market as the SBA plays a role in the sale process and their inability to participate negatively impacts secondary market sales. We have experienced and navigated through shutdowns before and continue to originate new business and close loans with guarantees. We have the financial strength and capacity to use our balance sheet and portfolio loans until the secondary market comes back to normal. More importantly, we'll continue to provide small businesses with access to capital and look forward for the resolution of the shutdown.
And with that, I'll pass the call over to Lindsay.
Lindsay Y. Corby - Executive VP & CFO
Thanks, Alberto. Good morning, everyone. I will start on Slide 4 with a review of our loan and lease portfolio. Our total loans and leases held for investment were $3.5 billion at December 31, a net increase of $45.8 million from the end of the prior quarter. Our originated loan portfolio increased approximately $172 million net. This increase was offset by a decline of $126 million in our acquired portfolio.
As Alberto mentioned, our payoffs were higher in the fourth quarter as we anticipated with approximately $111 million in payoff compared to $99 million in the prior quarter.
Moving on to deposits. On Slide 5, our total deposits increased $9 million to $3.75 billion at December 31. We saw the strongest growth in our noninterest-bearing demand deposits and our time deposits. This was offset by declines in other deposit categories. The increase in our noninterest-bearing demand deposits was driven by seasonal inflows from commercial relationship, which pushed up our average noninterest-bearing deposits by $18 million in the quarter. During the quarter, we were able to manage the time deposit costs, which helped us to reduce the increase in our cost of interest-bearing deposits compared with the 2 prior quarters.
Moving to Slide 6. I'll discuss our net interest income and margin. Our net interest income increased by approximately $700,000 due to higher balances of loans and leases. Accretion income decreased by $1.9 million from the prior quarter. Yields on earning assets expanded 5 basis points from 5.49% to 5.54%, which was offset by an 11 basis point increase in our cost of deposits, resulting in a 4 basis point decline in our reported net interest margin from 4.73% to 4.69%. When the impact of the accretion income is excluded, our net interest margin increased 14 basis points to 4.13%, primarily due to positive impact of loan repricing and higher rates on our new loan production. Yields on loans and leases excluding the accretion income expanded to 5.75% from 5.48% the previous quarter.
Turning to non-interest income on Slide 7. Compared to the prior quarter, our noninterest income increased by $3.4 million. This was primarily due to a $4.3 million increase in our net gains on government-guaranteed loan sales. This was the result of higher volumes of loans sold as well as a slight increase in average premium due to a more favorable mix of loans sold during the quarter. The higher interest rate environment continues to drive increased prepayment fees that are reducing the value of our servicing assets. In the fourth quarter earnings release, we expanded our disclosures around the net servicing fee income to break out the loan servicing revenue and the revaluation of the servicing asset to provide better visibility.
During the fourth quarter, we recorded a $2.9 million fair value adjustment to reflect the revaluation of our servicing asset, which once again reduced our net servicing fees this quarter. The loan servicing revenue was $2.7 million for the quarter, up slightly from $2.6 million in the prior quarter. The remaining fee income line items remained stable for the quarter, including our wealth management and trust business with $679,000 of revenue during the quarter.
Moving to Slide 8. Let's look at our noninterest expense. Our fourth quarter expenses include $1.3 million related to the significant items. Excluding these items, our noninterest expense increased 4.4% primarily due to higher loan and lease-related expenses, occupancy expense and professional fees. Our largest expense line item, salary and employee benefits, was relatively flat with the prior quarter. We expect to see the remaining cost savings projected for the First Evanston transaction in the second half of the year. That being said, we continue see the beneficial impact of the acquisition on our adjusted efficiency ratio, which improved to 54.95% in the fourth quarter.
Turning to Slide 9. We'll take a look at asset quality. We saw positive trends in the loan portfolio this quarter and it remains well controlled. Our nonperforming assets declined to 67 basis points of total assets from 71 basis points at the end of the prior quarter. Although we had some influence OREO, this was more than offset by a decline in our nonperforming loans and leases, largely related to government-guaranteed collection from the SBA on nonperforming government-guaranteed loans. As a result, the government-guaranteed balances in our nonperforming assets declined to $4.6 million from $7.3 million at the end of the prior quarter. Excluding government-guaranteed NPAs, our nonperforming loans to total loans ratio remained unchanged at 66 basis points. Our net charge-offs were $2.1 million or 24 basis points of average loans and leases for the quarter, essentially equivalent to the prior quarter. Charge-offs were primarily related to the unguaranteed portion of SBA loans.
Provision expense for the fourth quarter was $3.9 million. Fourth quarter provision included allocations of $2.5 million for originated loans and leases and $1.6 million for acquired nonimpaired loans. Relative to the prior quarter, our provision expense declined due to a reduction in specific impairment in the unguaranteed portion of the government-guaranteed portfolio.
Our provision for the fourth quarter increased our allowance for loan and lease losses to 72 basis points of total loans and leases from 68 points at the end of the prior quarter. And our coverage of NPLs, excluding the government-guaranteed portion, increased 7 basis points to 109 basis points from the prior quarter.
In addition to the traditional allowance as a percentage of loan and lease metric, we also analyzed the allowance in conjunction with the acquisition accounting adjustment impacting our acquired portfolio. At December 31, the acquisition accounting adjustments plus the allowance for loan and lease losses represented 169 basis points of total loans and leases.
With that, I'd like to pass the call back to Alberto.
Alberto J. Paracchini - President, CEO & Director
Thank you, Lindsay. Before opening the call to questions, I want to spend a few minutes talking about our outlook and strategic priorities for 2019. With respect to our Oak Park River Forest acquisition, we have received all required regulatory approvals. We've also submitted a registration statement to the SEC but are subject to some degree of timing uncertainty there due to the government shutdown. As a result, we aren't able to provide you with a target closing date at this point. Notwithstanding, we continue to move forward on our integration plans and still expect the closing to occur in the second quarter.
With each acquisition we do, our integration process gets better and we're well in our way with our Oak Park transaction. As was the case with First Evanston, we're partnering with a quality institution and team. We're excited about getting to work with our colleagues there and growing our business in the Oak Park and River Forest markets. As far as organic growth is concerned, we expect to continue to generate solid loan growth consistent with our guidance into mid- to high single-digit range. We're well positioned to capitalize on opportunities in the markets stemming from any dislocation both in terms of customers and talent. We built a solid platform. We'll continue to invest in it and have a unique position in the market. With respect to deposits, we remain focused on executing our relationship banking strategy and identifying opportunities in select customer segments that we can grow. We also remain on the lookout for opportunity to do smart transactions that allows us to add core deposits to the franchise.
Lastly, we'll continue to look for ways to gain efficiencies both on the revenue and expense side in order to increase our ability to invest in the business and gain operating leverage. As we start 2019, we have flexibility to support growth, take advantage of opportunities in the market and continue to increase franchise value.
With that, operator, we can open the call for questions.

(Operator Instructions) Our first question will come from Terry McEvoy of Stephens.
Terence James McEvoy - MD and Research Analyst
If I think about the first quarter outflow of noninterest-bearing deposits, which had a nice increase in the fourth quarter combined with just the impact of the recent fed rate hike in December, could you just talk about anticipated funding costs or deposit costs in the first quarter? And then, generally speaking, your thoughts on the core margin?
Lindsay Y. Corby - Executive VP & CFO
Sure. Terry, good morning. In terms of where we think things are going for the cost of deposits, I think there is, obviously, pressure out there in the market. I do believe that with the current market outlook for the fed hiking rates being more muted now, I do think that you're seeing some stabilization there. You're continuing to see pressure on the time deposits in the money market. So I do think that you'll continue to see competition there and that'll cause a slight increase in terms of deposit costs going forward. Related to your question about the commercial deposits and the inflow, that's typical again with our acquisition from First Evanston. They have larger commercial deposits that do tend to have these fluctuations from time-to-time and you will see that coming through. We continue to capitalize on their commercial banking relationships that they've had and new ones that we're bringing into the bank. So we're really pleased with the noninterest-bearing performance during the quarter. In terms of the outlook on the core margin, we are consistent in terms of what we've been guiding you to. We do think that you'll see some benefit during the first quarter from the December rate increase. So you may see a slight expansion in the first quarter, but relatively flat throughout the remainder of the year.
Terence James McEvoy - MD and Research Analyst
Great. And then just as a follow-up, given all the focus on leverage lending over the last month, I remember when you went public there was mention of a sponsored finance group that you started that had a portfolio about $125 million and, I guess, my question is, how much of that would be considered leverage loans? Has that portfolio grown in the last couple of years? And just any comments about the credit health, specifically, of that portfolio?
Alberto J. Paracchini - President, CEO & Director
Sure. So the portfolio size of that segment, I guess, or that part of our commercial portfolio, Terry, is just under -- just around $230 million plus or minus $2 million. I think as far as credit quality and performance, it's been very, very good. We don't see, at this point in time, any deterioration in that portfolio. Portfolio continues to perform well. One thing to note is despite the talk in the markets about loosening of standards, covenants, structure, pricing, we're in a segment of the market that is not -- it's -- we're -- tend to finance lower middle market companies being purchased obviously by sponsors, but we remain disciplined in terms of both pricing and structure. So I think the key thing for us there is to continue to see good transaction flow and just maintain our sell activity as we continue to grow in that business, but so far, so good. And Tim has some additional comments.
Timothy C. Hadro - Executive VP & Chief Credit Officer
I would just like to add that the one impact we have seen from changes in the marketplace is that our hit ratio has gone down. For every credit -- for every 10 credits we look at -- we are now successfully bidding and winning fewer credits than we were in the last several years.
Alberto J. Paracchini - President, CEO & Director
Yes, and I think, just to expand just briefly on that, I think we're very comfortable with that. Again, the key thing for us is just making sure that we continue to see good transaction flow, stay disciplined with our credit box and our model. And if our hit rate goes down, so be it, but as long as we continue to get the at bats, I think, we'll be fine in that business.

The next question comes from Michael Perito of KBW.
Michael Perito - Analyst
Couple of questions. I wanted to start -- I was hoping maybe we can spend a minute on the SBA side of the business amidst the government slowdown. I was wondering if -- can you give us a little bit more color about what type of production you guys are anticipating? Obviously, the fourth quarter seemed pretty strong and I know it can be choppy even without the government shutdown, so I was wondering, I guess, #1 of that piece. And then, on the other piece, if there is any other expected kind of flow through to the provision or expense line that, that could also have an impact on?
Alberto J. Paracchini - President, CEO & Director
I think more generally in terms of the shut down there, I think, Mike, as we said during our remarks, we have gone through these periods before. Our team there has experienced shutdowns. We anticipated that there would be a shutdown. And I think with respect to loans that we have in the pipeline where we were able to pool guarantees prior to the SBA shutting its doors, we continue to do business as usual. We'll close those loans. Obviously, we can't sell them until the shutdown is over, because the SBA is part of the sales process. And with them being kind of out of the picture, at this point, the secondary market is not operating normally. That being said, we are -- we have the capacity to hold loans until the market resumes. So I think that's just an issue of timing there in terms of waiting for the shutdown to end.
As far as new business is concerned, and this is business where we didn't have the business in the pipeline prior to the shutdown beginning, obviously, we can only go so far there in terms of -- at some point, we need to pull guarantees and, therefore, we're not going to be able to close new originations until the shutdown ends.
We obviously hope, we have no -- wish we had a crystal ball and we could tell you the shutdown is going to end soon. But, eventually, the shutdown will end, and I think business will resume. We'll be able to resume selling loans in the secondary market, pool guarantees on loans that we have in the pipeline and move forward. At this point, you asked question a little bit about credit quality there. Obviously, when we're trying to -- as you know, we have these loans in our nonperforming category where we have guaranteed potions, where we want to collect on the guaranty, obviously, timing there could be impacted because we're not able to collect on a guarantee from the SBA until the shutdown ends. But aside from that, we continue to operate the business. We're in this business for the long run. We have a good platform and we'll continue to support small businesses going forward.
Michael Perito - Analyst
Maybe if I ask the question a little bit differently, and you could disregard this first number. I'm just using as an example, but let's say, we were expecting you to do $31 million of revenue in the SBA business in 2019, does the shutdown alter potentially that number? Or does is just alter the timing of which that number will be recognized potentially over the course of the year?
Alberto J. Paracchini - President, CEO & Director
I think the further -- I -- we discussed this a lot internally. And, obviously, some of it is just an element of timing. The longer that shutdown goes, the more that timing will impact, call it, the calendar year so to speak, because things will slide. The flip side of that, which is, I think, the other part of your question is, does the -- the longer the shutdown goes, obviously, more small businesses are going to be impacted that depend on SBA financing. I don't think or at least our view is that doesn't mean that the demand goes away, so we tend to view it as more of a timing issue really impacting both sides.
Michael Perito - Analyst
Okay. Helpful, Alberto. And then maybe switching over to the expenses. Just kind of curious, Lindsay, maybe if you have any initial thoughts as you start to budget for next year. I mean, I think, if you adjust for some of the noise in the fourth quarter it was a little over $39 million, was the quarterly expense run rate, and it sounds like there's still -- while maybe nothing really major, still some efficiency focus that you guys are doing. So I mean, how should we be thinking about the expense build for next year? Obviously, you guys, obviously, continue to target having a growth posture?
Lindsay Y. Corby - Executive VP & CFO
Yes. I think you're really starting to see some efficiencies come through. Obviously, based on our results this quarter, you can see improvements just in terms of efficiency ratio and noninterest expense as a percent of average assets. Things are coming through slowly but surely there, and I do think that they'll remain elevated here for the first half of the year and then come down consistent with the guidance that we've given in the past, Mike, in terms of the acquisition. And we remain on track, and I feel comfortable with where we're heading. So there is always seasonality, too, just in our core numbers, excluding the acquisition because of the first quarter, you have higher payroll taxes. We have negative 5 degrees and snow here in Chicago. So there is always some seasonality here in this first quarter. So I think from a run rate standpoint, they will remain elevated for the first half. And then, you'll see the rest of it come through.
Michael Perito - Analyst
Okay. And then just lastly, if I could quickly just on the kind of the state of the Chicago market. Just curious if you started to notice any form of accelerated disruption or anything of note over the -- as we've approached year-end here and I assume there's starting to be some more year-end conversations at some of your competitors that could be involved in M&A transactions, et cetera. I was just curious if that were to come, maybe, you can give us a quick update on what you're seeing in the market?
Alberto J. Paracchini - President, CEO & Director
Yes. I think, look things slowed down on the M&A side. I think with equity markets -- with the performance of the equity markets in December, I think conversations that were ongoing and chatter, so to speak, that was out there in the market, I think got muted for a period of time. I think, markets have come back a bit. So I don't know, I think, it's too early to tell in terms of the level of activity that, I think, we can expect this year. But certainly, with valuations kind of where they are, I think, it goes without saying that, that's going to have some degree on impact on transactions. That being said, for us, look, we have very good flexibility at this point, we're -- profitability is up, we're generating capital, which gives us a lot of flexibility to grow organically, to take advantage of opportunities be it teams, be it obviously customers that are impacted here a bit by the disruption in the market. And as we said in our comments, to do smart transactions like we've done in the past. We're looking -- we can look to first and foremost to look for opportunities to acquire core deposits. And I think we remain focused on that, and if history is a guide there, I think we'll see our share of opportunities.
Operator
The next question comes from Nathan Race of Piper Jaffray.
Nathan James Race - VP & Senior Research Analyst
Lindsay, just going back to your comments around on the loan yield expansion this quarter and kind of your outlook there, I'm just curious given the prepayments that you guys had late in the quarter and so forth on the commercial real estate side of things, if there are any prepaid fees that may have kind of impacted the loan yields during 4Q?
Lindsay Y. Corby - Executive VP & CFO
Yes. That's a great question, Nate. No, it's pretty clean this quarter. There wasn't a lot in there that really stood out in terms of anything that would have accelerated. It was just blocking and tackling, good new production and we're seeing the impacts of the rate environment.
Nathan James Race - VP & Senior Research Analyst
Okay. Got it. Perfect. And then just kind of thinking about accretion in 2019, I know it can be tough to predict, and there is a decent step down versus what we had last quarter. I know the impact of OPRF probably in 2Q will have some impact as well, but just curious kind of what you guys have budgeted? Or how we should think about the progression of accretion income in 2019?
Lindsay Y. Corby - Executive VP & CFO
Yes, and like you stated, the accretion is one of those things where it's a point in time and subject to fluctuation, but I did guide you guys down in terms of that accretion levels and, as I stated, it's hard to give you an exact number. But I think you saw the variance between Q3 and Q4 to be around $2 million, let's call it. So I think if you use that as sort of a guide, if you will, it would probably be pretty good.
Nathan James Race - VP & Senior Research Analyst
Okay. Got it. And then just kind of last question on loan growth expectations on organic basis. It sounds like you guys still are looking at a good amount of opportunities and the pipeline's still pretty full heading into this year. So just curious if kind of high single digits is still kind of a reasonable expectation on organic basis for this year?
Alberto J. Paracchini - President, CEO & Director
Yes, I think, Nate, like we stated before, mid- to high-single digits is kind of what we're operating under. Obviously, payoff activity and some things that we really have no visibility on is really the key variable there. But in the mid- to high-single digits, it's still -- we're still comfortable with that guidance.
Operator
The next question will come from Andrew Liesch of Sandler O'Neill.
Andrew Brian Liesch - MD
Just a question on the increase on the gain on sale premium this quarter, you referenced in the release and in the presentation, it was probably due to mix shift. What was this mix shift?
Lindsay Y. Corby - Executive VP & CFO
Sure. The mix shift was primarily USDA loans. So Andrew, when you sell a USDA loan, number one, you don't share any of the premium with the government. So it's all ours. And then, number 2, the premiums tend to be higher given the fact that there are prepayment penalties with USDA loans, so the premiums on those tend to trend higher.
Andrew Brian Liesch - MD
Got you. Okay. But my other question just revolves around the C&I growth this quarter, it's certainly impressive. I'm just curious what's driving that? Is it you're taking market share from other players? Is it business expansion from existing customers? Is was just -- it was solid, I'd just like to know what's driving it?
Alberto J. Paracchini - President, CEO & Director
I think you answered it, Andrew. I think it's a combination of both and the fact that we have our combined team now, so we took the -- what was formerly the First Evanston team and now is the Byline team with ours. They're operating -- we've integrated that. They're operating as a unit, focused on looking at opportunities and taking care of customers. But I think you answered the question by the 2 statements that you said. It's a function of -- we're seeing customers certainly look for expansion opportunities in terms of whether it'd be equipment, whether it'd be expanding facilities, whether it'd be -- we're seeing some of that with existing customers. And I think we're seeing also opportunities to take share in the market as well.
Andrew Brian Liesch - MD
Okay. Do these commercial customers, the new ones anyway, come with deposit relationships?
Alberto J. Paracchini - President, CEO & Director
Yes, sir.
Andrew Brian Liesch - MD
So that would be a source of noninterest-bearing account growth?
Alberto J. Paracchini - President, CEO & Director
Yes. And I think in -- that's my reference to my -- in reference to my remarks as far as deposits is concerned, that is correct and that is our relationship banking strategy there.
Operator
(Operator Instructions) Our next question will come from Sean Tobin of FIG Partners.
Sean Tobin - Associate
I guess, just starting on the provision. The provision has bounced around due to the government-guaranteed portfolio. Can you give us any color on how to think of the reserve in the next couple of quarters or even the next year?
Lindsay Y. Corby - Executive VP & CFO
Sure. In terms of the provision for this quarter, it was around $4 million, which was lower than the previous quarter, and was a reflection of the improvement in terms of the nonperforming loans coming down and just some improvements in terms of some credits on the SBA side. So I think on a go-forward basis, you'll continue to see consistent inflow and outflow from the SBA business, and so we'll continue to provision accordingly under GAAP for that and continue to see our reserve grow in proportion to our loan portfolio. So the bulk of the provision has really been coming from the growth that we've been experiencing. So I think you'll see consistent trends in regards to that. Tim, I don't know if you have anything to add to that.
Timothy C. Hadro - Executive VP & Chief Credit Officer
I would to add to that the -- in any given quarter, the amount of provision we take is, as Lindsay said, largely from new originations. But it depends on what sector of our lending operations is doing particularly well that quarter because we assess different loss factors based on the type of lending it is. General C&I lending is -- we have certain factors and some of the, what I'd characterize as perhaps higher risk, higher return, we use higher loss factors. So it really depends on the mix of business we do during the quarter.
Sean Tobin - Associate
Understood, understood. That's very helpful. And then, I guess, switching to fees. We saw servicing fees kind of jump around quite a bit in 2018. How should we think about that going into the next year?
Alberto J. Paracchini - President, CEO & Director
I think before I pass this question on to Lindsay, one thing to note there is, because we've seen it in some of the releases from some other institutions is, so this year, in this quarter, so you saw the fair value charge or cost that is embedded in our numbers related to the servicing asset that we have for the SBA guaranteed business. I think as -- for the first time, we're starting to provide you with more detail so that you can see the breakup between what is fair value adjustments that we're making to the asset itself vis-à-vis the underlying trend of servicing income coming in. So I think, hopefully, that's more color for you guys and that gives you a little bit more clarity there in terms of what's driving that particular line.
Lindsay Y. Corby - Executive VP & CFO
Yes, right. I think, Alberto was spot on and that's why we broke it out. And going forward, I think, what's really been driving that volatility was the prepayment fee. They increased here in the second half of the year. And so will those slow down, time will tell. We think so, but we don't have a crystal ball here. So that's what drove it, historically, and we'll see what happens next year.
Operator
And this concludes our question-and-answer session. I would like to turn the conference back over to management for any closing remarks.
Alberto J. Paracchini - President, CEO & Director
Great. Thank you, operator. So I would -- first, I'd like to thank you for joining us today. Thank you for your interest in Byline, and we look forward to speaking to you again next quarter. Thank you.
Operator
The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
