At this time, I'll turn the call over to Kevin P. Riley. Kevin?

Kevin P. Riley
CEO, First Interstate BancSystem

Thanks, Lisa. Good morning. Thanks again to all of you for joining us on our call today. This quarter, along with our earnings release, we have published an updated investor presentation that has additional disclosures that we believe would be helpful. The presentation can be accessed on our investor relations website. If you have not downloaded a copy yet, I encourage you to do so. I'm going to start off today by providing an overview of the major highlights of the quarter. Then I'll turn the call over to Marcy to provide more details on our financials. Our fourth quarter performance capped off a very strong year for the company as we executed well on the integration of our merger with Great Western, realizing cost synergies we projected for the transaction while continuing to generate solid organic loan growth throughout our footprint.

Specific to the fourth quarter, it was a bit noisy, with a handful of cleanup items that should set the stage for a strong 2023. While these items had a $0.07 impact on earnings per share in the quarter, we continued to execute well and saw continued positive trends in our loan growth, core margin expansion, and asset quality. As a result, excluding selected items, which we will walk you through, the company generated $0.89 of earnings per share. It is worth noting that this quarter included a $0.07 less contribution from purchase accounting accretion because of fewer early payoffs. We also added to our already robust allowance for credit losses despite continued improvement in asset quality and only 2 basis points of net charge-offs in the quarter.

As you can see on slide 10 of the investor deck, our ACL coverage ratio has expanded meaningfully over the last two quarters. With this strong financial performance and a positive shift in AOCI, we saw a 2.3% increase in our book value per share and a 4% increase in our tangible book value per share from the end of the prior quarter. The banking environment continues to be favorable for us in the fourth quarter, which we were able to take advantage of given our strong capital and liquidity position. Many banks seemingly to pull back on loan production due to capital and funding constraints, we were pleased with our ability to win deals. On our larger footprint and increasing production from our newer markets, we saw plenty of high-quality lending opportunities.

While maintaining our conservative underwriting criteria, we were able to generate our highest level of loan growth of the year, with total loans increasing at an annual rate of 11.1%. Going forward, we will be selective in our growth opportunities as the environment remains uncertain and funding is less bountiful. We are prudently planning for a slower pace of growth in 2023 than we experienced in the second half of 2022. The largest area of growth during the quarter came in our commercial real estate, much of which was the result of construction loans moving into this portfolio. The majority of these projects were multifamily properties, which, given the high constraint in many of our markets and the significant demand of affordable housing, are strong, low leverage credits that we are adding to the balance sheet.

Overall, the average rate on our new loan production in the fourth quarter was between 5.5% and 6%, which was up considerably from the prior quarter and progressively increased as the quarter went on. The average rate on loans funding on the balance sheet was lower as prior construction commitments made earlier in the year funded this quarter. This trend will impact us for the next several months with projects in process. On the deposit side, we indicated on our last earnings call that we expected balance to be relatively flat in the fourth quarter, and they were earlier in the quarter. The outflow in the fourth quarter was concentrated in the month of December. While it appears the outflows were largely seasonal in nature, there is an element of depositors putting some of their excess liquidity to work.

Going forward, while our base case for 2023 suggests flat deposit balances year-over-year, we do expect normal seasonal declines in the first quarter. We also anticipate a mix shift out of non-interest-bearing and lower cost balances into our Indexed Money Market and CD specials. You should expect to see deposit betas increase accordingly, but remain relatively benign over the full cycle when compared to prior cycles. In terms of time deposits, as the third quarter, we continue to selectively utilize our ability to offer higher rates to add and to retain profitable long-term relationships. While this has placed some upward pressure on our deposit costs, to this point, the expansion in earning asset yields has outpaced those increases. Our adjusted net interest margin expanded by another 2 basis points this quarter.

While this margin expansion trend will be harder to sustain going forward due to balance sheet mix, we do anticipate to see good year-over-year net interest income growth in 2023. Despite the more challenging economic conditions, our asset quality trends were favorable again this quarter, with total non-performing assets declining by 24% and net charge-offs of just 2 basis points. Criticized loan balance were modestly higher. However, there was nothing unusual about the inflows we experienced here. As you know, credit was the biggest question mark heading into the acquisition, and our board recognized that as well. During the fourth quarter, we exceeded targets of targeted reductions of non-performing assets and criticized loans set by our board. This resulted in a $4.2 million incentive compensation adjustment you see referenced in our material.

Overall, the portfolio continues to perform extremely well, and we are pleased with the significant improvements we have made since closing the Great Western acquisition. With that, I'll turn the call over to Marcy for some additional details around the fourth quarter results. Go ahead, Marcy.

Marcy Mutch
CFO, First Interstate BancSystem

Thanks, Kevin, and good morning, everyone. Just to make sure we're providing clarity, I'll start by summarizing the notable items that impacted our financial results in the fourth quarter. We had $3.9 million in merger-related expense. $4.2 million of additional incentive compensation related to asset quality improvement, which Kevin mentioned. A $1.3 million additional litigation accrual, which has now been settled, and a $400,000 reduction to the fair value of loans held for sale. In aggregate, these items had a $0.07 per share impact on our fourth quarter financial results. Additionally, the purchase accounting accretion declined by $9.3 million from the prior quarter, or $0.07 per share due to lower levels of early payoffs.

I'll move into the rest of our financial results, which, unless otherwise noted, will be in comparison with the third quarter of 2022. Our fully tax equivalent net interest income decreased by $8.2 million, which was entirely due to a lower impact from purchase accounting accretion, as I just noted. Excluding purchase accounting impacts, net interest income increased by $1.4 million. Our reported net interest margin decreased 10 basis points from the prior quarter to 3.61%. Excluding purchase accounting accretion, our adjusted net interest margin increased by 2 basis points to 3.49% from the prior quarter, driven by a favorable shift in our earning asset mix and an increased yields on loans, investments, and cash. This offset the 36 basis point increase we saw on our cost of funds.

As you have likely already noted, with strong loan growth and deposit outflows, we increased our use of short-term borrowings in the quarter, which ended a little over $2.3 billion. As noted on page 14 of the investor deck, cash flows off the securities portfolio should mostly fund loan growth from here, the higher balances of wholesale funds to start the quarter will mean we will see some compression in our adjusted net interest margin in the first quarter. From there, the net interest margin percentage will be a function of the mix of both earning assets and liabilities. During the quarter, we added $850 million in notional forward starting receive fixed swaps against both loans and investment securities. Together with the changes in the composition of our balance sheet, we are now essentially neutral to changes in short-term rates.

In 2023, net interest income growth will come from a combination of net loan growth and the remixing of our assets out of securities into loans and our liabilities out of borrowings into deposits. Ex purchase accounting impacts, we expect Q1 2023 net interest income to be down compared to Q4 2022, primarily as a result of lower day count and some margin compression. For the full year 2023, we expect net interest income growth to be in the low double digits, again, excluding purchase accounting accretion. As you can see on slide 12 of the investor presentation, we expect scheduled purchase accounting accretion to be about $15.8 million in 2023. This does not include accretion from early payoffs, which will likely be immaterial in 2023 given the current interest rate environment.

Overall, for 2023, we expect average earning assets to remain relatively unchanged from Q4 2022 levels at around $29 billion. Our total non-interest income increased $18.7 million quarter-over-quarter to $41.6 million, primarily due to the loss on investment securities realized in the third quarter. Excluding investment securities losses, non-interest income fell short of our expectations, declining by $5.5 million from the prior quarter. This included a net $400,000 reduction to the fair value of loans held for sale, a decline in swap revenue to near zero, and lower payment services revenue resulting from declines in transaction volumes. We also increased our earnings credits in the quarter, which reduced our service charges on deposit accounts.

For the full year 2023, as a result of the NSF and overdraft fee changes we made partway through 2022, lower swap revenue and other fee income expectations, we expect non-interest income to decline by low single-digit % when compared to reported 2022 revenue, excluding the securities losses. Second half results are likely to be stronger than the first half of the year as we begin to realize revenue synergies within the Great Western footprint. Moving to total non-interest expense. While it was a little messier this quarter than anticipated, on a run rate basis, we landed where we expected in the range of $163 million-$165 million.

As noted earlier, reported results included a $3.9 million acquisition expense, $4.2 million in performance-related incentive adjustments, a $1.3 million litigation accrual, as well as a $2.2 million expense related to the write-down of an OREO property. Net of these items, non-interest expense was $163.7 million, and our run rate efficiency ratio would be closer to 53% in the fourth quarter, which by definition would also exclude the $4.1 million of intangible amortization expense. For the full year 2023, we expect operating expenses to increase in the 3%-4% range from the full year 2022 expense base of about $647.1 million, excluding merger expenses.

The 2 basis points FDIC surcharge accounts for 1% of that growth, or around $6 million. Moving to the balance sheet. Our loans held for investment increased $496 million from the end of the prior quarter, with growth in all major portfolios with the exception of construction and commercial. As Kevin mentioned earlier, the decline in construction loans was primarily attributable to projects being completed and moving into our commercial real estate portfolio. On the liability side, our total deposits decreased $811 million, with much of the decline coming in non-interest-bearing deposits due to the seasonal outflows and clients utilizing some of their excess liquidity, as Kevin noted earlier. This was partially offset by increases in our balances of time deposits as we see more customers taking advantage of the higher rates now being offered.

The net outflow was in business deposits, and we were encouraged that consumer deposits held flat. Moving to asset quality, we continued to see positive trends, with non-performing assets declining 24%. Criticized loans increased only modestly from last quarter. Our loss experience continues to be very low, with net charge-offs of just $1.1 million, or 2 basis points of average loans in the quarter. Strong loan growth and qualitative additions related to a more conservative economic forecast pushed our funded allowance up by $7.1 million from the prior quarter, resulting in a modest increase to our ACL to 1.22% and an increase in our coverage of non-performing loans, which now stands at 3.3x . Our total provision expense for the quarter was $14.7 million, which included $6.5 million related to unfunded commitments.

With that, I'll turn it back to Kevin.

Kevin P. Riley
CEO, First Interstate BancSystem

Thanks, Marcy. Now I'll wrap up with a few comments on our outlook and priorities for 2023. 2023 is shaping up to be a more challenging year, with more uncertainty around the macroeconomic environment and the path of future interest rates, which is complicated by the quantitative tightening. While we are mindful of these circumstances, our franchise has never been stronger and our balance sheet is in great shape with strong levels of capital, liquidity, and reserves. We believe we are well-positioned to effectively manage through a wide range of economic scenarios and continue to play offense. With a loan-to-deposit ratio in the low seventies and strong credit quality, our fundamentals are strong. Our core deposit base will remain a focus this year, which as you all know, is core to the strength of our franchise.

We also will continue to focus on scalability, automating manual processes, enhancing our product sets, and rightsizing our departments while maintaining talent. As the company has grown over the past decade, we have not deviated from our conservative approach to loan underwriting and risk management. 2023 will be no different. As Marcy and I have alluded to, the pace of net interest income growth is likely to moderate when compared to the past few quarters. We are focused on what we can control. We will remain highly selective in loan growth we are booking, which should yield mid-single digit growth in 2023 while moderating from the double digit pace we have delivered in recent quarters. We believe this level of activity is prudent for what we see in our markets today. Going forward, we intend to have greater focus on C&I.

To support this effort, we plan to launch an ABL business later this year, and we will redouble our efforts in our small business lending. We are actively pursuing new household growth and deepening existing relationships to generate favorable deposit trends. We are viciously pursuing the many synergistic opportunities the Great Western acquisition affords us, which is a differentiator for First Interstate this year. We expect these to show up in payment services, home lending, treasury management, and indirect. We have, and we will continue to be out front actively managing our credit book. As such, at this point, we do not see significant credit deterioration on the high horizon. Finally, we will remain vigilant in managing our expenses and expect to deliver a solid year of positive operating leverage as we drive toward a sustainable efficiency ratio in the low 50s.

In wrapping up, I would be remiss not to thank Russ Lee, who retired at the end of the year. Russ joined us after our INB acquisition and has been instrumental in moving us forward since that time. I'd also like to welcome Ashley Hayslip our new Chief Banking Officer. Ashley has joined the team in a challenging banking environment, but we are confident that she will help us continue to grow our client base. With this addition, I have an executive team in place that I am very excited about. They are diverse in age, gender, and background. I am confident they'd have the ability to continue to move the company forward. I would also like to take a moment to acknowledge Ross Leckie, who retired from our board of directors earlier this month after having served as a director for more than a decade.

On behalf of the entire board, I want to thank Ross for his many years of valuable service to our company. In summary, while we expect 2023 to be a challenging year from a macro perspective, these are times when the strength of our franchise is most valuable. We are well positioned to protect shareholder value during an economic downturn while continuing to make progress on strategic initiatives that we believe will continue to enhance the long-term value of our franchise. Ultimately, given the strong execution we are seeing throughout the organization, we believe 2023 will prove to be another positive year for the company and our shareholders. With that operator, I will open the call up for questions.

Operator

Thank you. If you would like to ask a question today, please press star followed by one on your telephone keypad. If you'd like to withdraw your question, please press star followed by two. When preparing to ask a question, please ensure your phone is unmuted. Our first question today goes to Jared Shaw of Wells Fargo Securities. Jared, please go ahead, your line is open.

Jared Shaw
Analyst, Wells Fargo Securities

Hey, everybody. Good morning.

Kevin P. Riley
CEO, First Interstate BancSystem

Good morning, Jared.

Jared Shaw
Analyst, Wells Fargo Securities

Just, I guess a couple of questions. Maybe first on funding. You know, it definitely seems like there's been a shift in the outlook on funding in sort of your comments last quarter on the expectation for beta being smaller or lower. How should we be thinking about funding costs from here? Do you think that we get back to DDA or when do DDA balances recover or should we expect that they continue to outflow? Are the FHLB borrowings more temporary until we see that reversal? Or do you think we could rely on higher FHLB borrowings for a while?

Kevin P. Riley
CEO, First Interstate BancSystem

Well, I think the FHLB borrowings will be here for a while, Jared. Hopefully during 2023, we see a shift, you know, as they slowly go out, and reduce over time. That's what we expect to see. Yes.

Jared Shaw
Analyst, Wells Fargo Securities

What about beta from here on the remaining deposits? Where do you see that peaking out?

Marcy Mutch
CFO, First Interstate BancSystem

Jared, at this point we've said all along that our last cycle beta was 27. We're still below that right now. You know, we expect it to kind of still stay in that range. It may bump up a little as we, you know, increase deposit costs, but nothing material at this point.

Jared Shaw
Analyst, Wells Fargo Securities

Okay. Then on the asset yields, the loan yields were a little weaker than we were looking for and heard your comments on, you know, the funding of loans that were previously committed. Where should we be thinking loan yields trend from here? Are you starting to see any ability for spread widening?

Marcy Mutch
CFO, First Interstate BancSystem

New loan yields are coming on in the high 5s. We'll still be hampered by those construction loans that are funding at lower rates. Will be below kind of our core loan yield.

Jared Shaw
Analyst, Wells Fargo Securities

Okay. All right. I guess maybe just shifting to expenses. When you look at the expense base that we should be growing off of, I guess that includes some of the stuff that you're calling out as non-recurring this quarter. Is that, is that one the right way to be looking at it? Two, when you look at that incentive comp that happened this quarter, what are the incentive targets for next year that we should be thinking about as triggers for potential incentive payments through 2023?

Kevin P. Riley
CEO, First Interstate BancSystem

Well, the incentive comp is going pretty much back to the normal incentive comp plan that we've had in our proxy for years. It's not going to change. This was just a unique item so that, you know, the board and management would focus really on asset quality. Because going into the Great Western acquisition, you know, that was probably the biggest question on everybody's mind. That was just one additional aspect. There's no real other changes with incentive comp with regards to what our normal practices have been.

Marcy Mutch
CFO, First Interstate BancSystem

Jared, as far as, you know, the 647, if you, I mean, we talked all year about the fourth quarter, you know, kind of base run rate to be around between $160 million and $161 million. If you take that quarterly run rate times somewhere between 3% and 4% inflation plus the FDIC insurance adjustment, you get to the same place. Again, we were just trying to simplify that by using the 647 expense base, you know, with between 3% and 4% inflation, and that includes the FDIC insurance. You get the same place either way.

Jared Shaw
Analyst, Wells Fargo Securities

Okay. Okay, thanks. Just finally for me, maybe, you know, thoughts on capital management here. You bought back stock earlier in the year at higher prices. You know, how do you, how do you feel about capital ratios here and potential for buybacks?

Kevin P. Riley
CEO, First Interstate BancSystem

Well, Jared, you know, as you know, you've been around us for a long time. We have a number of arrows in our quiver that we use. We look at how to effectively use our capital. That's one of them. We always are analyzing our capital levels and what we might do going forward. That's all I can pretty much say on that.

Jared Shaw
Analyst, Wells Fargo Securities

Okay. Thanks.

Marcy Mutch
CFO, First Interstate BancSystem

Thank you.

Operator

The next question. The next question goes to Chris McGratty of KBW. Chris, please go ahead. Your line is open.

Chris McGratty
Analyst, KBW

Oh, great. Thanks. Thanks for the question. I guess, Kevin or Marcy, the math you gave us on the growth in the margin maps very similarly to the earnings that you gave when the merger was announced, you know, 365 or so ±. We've had much higher rates. It feels like there's been a notable change. Obviously, the margin's getting harder for everyone. I guess, what am I missing that changed so much in the earnings power?

Marcy Mutch
CFO, First Interstate BancSystem

Deposit outflows in 2022.

Kevin P. Riley
CEO, First Interstate BancSystem

Then also we had, as you recall, we reduced our NSF and OD, you know, fees.

Marcy Mutch
CFO, First Interstate BancSystem

The FDIC insurance is an additional, you know, expense that we didn't anticipate, so.

Chris McGratty
Analyst, KBW

Okay. Yeah. It feels like I get the NSF and FDIC. It feels like it's more the NII and the deposits that are leading.

Marcy Mutch
CFO, First Interstate BancSystem

Absolutely. It's the deposits.

Chris McGratty
Analyst, KBW

Yeah.

Marcy Mutch
CFO, First Interstate BancSystem

Yep.

Kevin P. Riley
CEO, First Interstate BancSystem

Mainly deposits, Chris.

Chris McGratty
Analyst, KBW

Yep, I get it. Kevin, in terms of next step for, maybe following on Jared's question, what are the thoughts on doing another deal? Obviously the balance sheet's in great shape. You got a ton of capital. Good deals get struck when really no one wants to do them. What are the thoughts on doing a deal?

Kevin P. Riley
CEO, First Interstate BancSystem

I get that question asked all the time, maybe because I do deals. The thing is, Chris, I'll be honest with you. It, it's, you know, right now, you know, I think when you look at banks, people are worried about the AOCI, where that's gonna go. People are worried about credit, where that might go. You know, what we're focused mainly on right now is preparing this institution to be scalable. We're making all the operations and everything, and get prepared if one comes about. We're not gonna rush into anything. We're more focused on driving positive operating leverage within the institution. If something comes up that's, you know, that we believe, as you always know, we have a priority list of banks that we believe will increase the franchise value of this company.

We're kind of sticking to that list. If something comes along, we'll look at it. A s you probably know, there's a lot of banks out there for sale, but we're not interested in all the ones that are out there for sale. We're gonna stick to our knitting and make sure this bank is performing at the ultimate level of performance. If something comes up that we believe will increase the franchise value, we'll go there. Nothing's right currently on the horizon.

Chris McGratty
Analyst, KBW

Okay. Thank you very much.

Operator

Thank you. The next question goes to Adam Butler of Piper Sandler. Adam, please go ahead. Your line is open.

Adam Butler
Analyst, Piper Sandler

Hey, good morning, everybody. This is Adam on for Matthew Clark.

Marcy Mutch
CFO, First Interstate BancSystem

Hi Adam

Adam Butler
Analyst, Piper Sandler

Just to go back to Jared's question on the deposit balances. Overall, they came down this one quarter. Do you expect a similar decrease in the first quarter, or maybe slower? Curious about your timing on that.

Kevin P. Riley
CEO, First Interstate BancSystem

Well, seasonally, if you go back, I mean, as you know, the pandemic threw all sorts of seasonal trends out of, out of whack. If you go back earlier, you know, a week before the pandemic, seasonally, we see a little bit decline in the first quarter. We start seeing deposits start picking up in the second quarter and faster in the third. That's kind of the seasonal direction. That's kind of what we're expecting this year, because I think what we have seen as the excess deposits go out in 2022, that's slowing down. Go back to our beta in a sense, where a lot of our deposits, we increased our deposit pricing a while back with Indexed Money Market account and CD rates.

A lot of our customers have been already migrated over to some of these products and are satisfied. We're just expecting maybe a little bit of seasonal decline in the first quarter, but feel that things will start moving in the right direction once we start going further into the year.

Adam Butler
Analyst, Piper Sandler

Okay. That makes sense. Thank you. Moving over to credit. I know that you mentioned that the uptick in criticized here isn't of concern, but I was wondering if you could provide some additional commentary on kind of where that came from. Was it several credits, geography or sectors?

Kevin P. Riley
CEO, First Interstate BancSystem

Okay, we're going to have our Chief Credit Officer, Michael Lugli address that question. Michael.

Michael Lugli
Chief Credit Officer, First Interstate BancSystem

Yeah. Overall, the portfolio, there was no overall decline in the portfolio. In fact, it did fairly well. It was really driven by three relatively large credits that totaled a little over $98 million, which drove down our criticized performance. That increased that by a corresponding $38 million. If you can't net those three credits out, but if you look at the overall portfolio, the trend was actually positive in criticized.

Adam Butler
Analyst, Piper Sandler

Okay. Makes sense. That's all the questions that I have. Thank you for taking them.

Kevin P. Riley
CEO, First Interstate BancSystem

Thanks, Adam.

Marcy Mutch
CFO, First Interstate BancSystem

Thanks, Adam.

Operator

Thank you. The next question goes to Andrew Terrell of Stephens. Andrew, please go ahead. Your line is open.

Speaker 14

Hey, Kevin and Marcy. This is Zach on for Andrew real quick. Just some housekeeping questions here. Do you have the monthly December NIM available?

Marcy Mutch
CFO, First Interstate BancSystem

Yeah. Monthly NIM was in the low three fortys. X purchase accounting.

Speaker 14

Gotcha. Do you happen to also have the spot on the interest-bearing deposits at 12/31?

Marcy Mutch
CFO, First Interstate BancSystem

Yeah. It was in the high 70s.

Speaker 14

Perfect. That's all I've got. Just some housekeeping questions. I appreciate you taking them.

Marcy Mutch
CFO, First Interstate BancSystem

Thank you.

Kevin P. Riley
CEO, First Interstate BancSystem

Thanks.

Operator

Thank you. The next question goes to Todd Mihm of RBC Wealth Management. Todd, please go ahead. Your line is open.

Todd Mihm
Analyst, RBC Capital Markets

I appreciate it. Today's results were clearly a sizable operational miss on earnings reflected in the stock price today. Prior calls that I've listened to, you guys have been very optimistic about the operations. Seems to me that there's a notable change in that viewpoint. Can you address why investors should have the same kind of confidence in you based on this quarter's results as they should have maybe previously?

Kevin P. Riley
CEO, First Interstate BancSystem

Wow. That's pretty sorry. I would say that the operating performance, you know, is strong. It might not be, you know, kind of if you go back and look at the earnings projections or what's up, people under thought what we were going to perform earlier in 2022, in my belief, they overestimated what we're going to end up. You know, the performance of the company really hasn't changed much. The only thing that I would say that's different is that we had some deposit outflows in the fourth quarter that we didn't anticipate, but the fundamentals of the operation of this company have not changed at all, and quite frankly, get stronger and stronger month by month.

Todd Mihm
Analyst, RBC Capital Markets

Well, I get that, but this is clearly an operational miss by a significant amount. I guess I'm a little bit taken aback by why that's surprising.

Kevin P. Riley
CEO, First Interstate BancSystem

It's not an operational miss by much by us. That's just your perspective.

Todd Mihm
Analyst, RBC Capital Markets

Okay. I appreciate it.

Operator

Thank you. The next question goes to Bruce Yerkes of Advisory Research. Bruce, please go ahead. Your line is open.

Bruce Yerkes
Analyst, Advisory Research

Yeah, thanks for taking my call. I know that Glacier reports at the same time as you, in looking at cost of funds, your cost of funds widened compared to theirs. I mean, you guys were at 28 basis points in the third quarter. They were 15, so there was a 13 BIP gap. You're 64 in the fourth quarter, they're 35. Now it's a 29 BIP gap.

I'm just wondering if you've had a chance to look at, you know, how they performed on that side and you could explain maybe what the differences are, and why yours, gapped out more than theirs.

Kevin P. Riley
CEO, First Interstate BancSystem

Well, have you seen their deposit performance this quarter?

Bruce Yerkes
Analyst, Advisory Research

I haven't looked.

Kevin P. Riley
CEO, First Interstate BancSystem

So the thing is this, is the gap out is because we're trying to take care of our customers and retain deposits by paying up, you know, and putting people into money market accounts and CDs. We started that back in the third quarter and in taking care of our customers. The fact of the matter is, if you look at our performance, our margin has expanded. Their margin barely expanded over the second and third quarter. This quarter it went down. I think they're only net up in the quarter and their margin a little over 6 basis points or so. It's a whole different ballgame. We're making a lot more money on the rate increases, We can afford and still have margin expansion by paying our depositors and trying to retain that business.

It's just a different model.

Bruce Yerkes
Analyst, Advisory Research

Why isn't it dropping to the bottom line?

Kevin P. Riley
CEO, First Interstate BancSystem

Oh, yeah.

Bruce Yerkes
Analyst, Advisory Research

They were a lot closer. They were a lot closer on earnings. All right.

Kevin P. Riley
CEO, First Interstate BancSystem

To whose earnings? these are analyst expectations.

Bruce Yerkes
Analyst, Advisory Research

I'm aware of that, you know, people are going off of the guidance that you provide on a quarterly basis, and there was clearly a difference in expectations versus what happened. That's what's driving my question. You just said you made a lot of money, and I'm just asking, if that's the case, why didn't it fall to the bottom line? Why wouldn't it have been better to sell some securities, let that part of the portfolio run off, let the loan-to-deposit ratio go up instead of taking on expensive borrowings?

Kevin P. Riley
CEO, First Interstate BancSystem

Well, if you I'm not going to get into how you run a balance sheet because let somebody else talk about that. That's not an effective approach. We'll take the next question, please.

Operator

Yes, our next question goes to Jeff Rulis of D.A. Davidson. Jeff, please go ahead. Your line is open.

Speaker 13

Hi. Good morning. This is Andrew on for Jeff today. Just a couple quick questions on loan growth. You guys noted earlier higher production in new markets, and you're seeing opportunities to grow new loans. I was just wondering where you guys are seeing the most growth and the most opportunities by state or by region?

Kevin P. Riley
CEO, First Interstate BancSystem

The interesting thing, quite frankly, it's pretty even across our whole footprint. There wasn't really any one market that outperformed another. It's pretty level across our whole footprint.

Speaker 13

Got it. That's helpful. Then another one kind of following up on that. Are you guys winning new relationships in those new markets, or are they just good markets in general?

Kevin P. Riley
CEO, First Interstate BancSystem

I think we're winning relationships because we're growing the assets. We have net customer or account increases. We are winning customers. It's again, pretty much even across our footprint.

Speaker 13

Got it. That's super helpful as well. Thank you. I'll step away.

Operator

Thank you. As a reminder, if you would like to ask a question today, please press star followed by one on your telephone keypads. We have a follow-up question from Chris McGratty of KBW. Chris, please go ahead. Your line is open. Hi, Chris. Your line is open.

Chris McGratty
Analyst, KBW

Oh, that was me. I did. Sorry about that. The comment in the deck about being neutral to rates with the balance sheet today. It would feel like that's perhaps on the conservative side of the Fed cuts. The Fed cuts, the pressure on the funding would seemingly ease. I guess, number 1, do you kind of agree with that? Two, can you just remind me, Marcy, the full beta assumption that's in the 23 guide? Thanks.

Marcy Mutch
CFO, First Interstate BancSystem

We haven't provided the full beta assumption in the 2023 guide, Chris. Your first assumption would be accurate.

Kevin P. Riley
CEO, First Interstate BancSystem

Chris, what we're trying to do is, as we said in the past, you know, many calls, is that we were rotating our balance sheet to be less asset sensitive and to prepare for the downturn. I think, you know, we struck some good derivatives or interest rates swap that Marcy mentioned earlier to hedge that portfolio with a variable rate loans on the way down in a higher rate environment. As you can see, the yield curve has dropped off dramatically. We're trying to protect the balance sheet on the way down.

Bruce Yerkes
Analyst, Advisory Research

Got it. Thank you. Thank you very much.

Operator

Thank you. We have another follow-up from Andrew Terrell of Stephens. Andrew, please go ahead. Your line is open.

Andrew Terrell
Analyst, Stephens

Hey, good morning.

Marcy Mutch
CFO, First Interstate BancSystem

Good morning, Andrew.

Andrew Terrell
Analyst, Stephens

All right. Just a quick question. Thinking about the mid-single digit loan growth guidance. I guess, can you help me out with some color on just what the incremental margin on a dollar of loan growth is for you today? Just understanding that the funding costs could be a little bit higher. Just what is the incremental spread that you're earning on mid-single digit growth look like relative to the 360 or so margin in the fourth quarter?

Marcy Mutch
CFO, First Interstate BancSystem

Well, Andrew, that's, it's kind of a mixed bag. New loan growth again is going on in the high 5s. What's gonna dampen the overall yield is the construction book that's funding closer to kind of our core loan yield today, which is high 4s. It's gonna be that mix of funding that kind of impacts.

Andrew Terrell
Analyst, Stephens

Do you have the-?

Marcy Mutch
CFO, First Interstate BancSystem

Of influence.

Andrew Terrell
Analyst, Stephens

Yeah.

Marcy Mutch
CFO, First Interstate BancSystem

Go ahead.

Andrew Terrell
Analyst, Stephens

Do you have the dollar amount of that construction book that is funding in that kind of territory? I'm just trying to quantify that impact.

Marcy Mutch
CFO, First Interstate BancSystem

We don't. We don't. That's not something that we disclose.

Andrew Terrell
Analyst, Stephens

Okay. fair enough. Then the last thing for me, just more housekeeping was on just the tax rate. What's driving the step up in tax rate?

Marcy Mutch
CFO, First Interstate BancSystem

It has to do with some accounting around LIHTC. It's coming up a little bit.

Andrew Terrell
Analyst, Stephens

Okay. Thank you for taking the follow-ups.

Marcy Mutch
CFO, First Interstate BancSystem

Thank you, Andrew.

Operator

Thank you. Our next question goes to Tim Coffey of Janney Montgomery Scott. Tim, please go ahead, your line is open.

Tim Coffey
Analyst, Janney Montgomery Scott

Great. Thanks. I appreciate the opportunity to ask a couple questions here. Apologize if I missed it, but Marcy, what is the cash flow coming off the securities portfolio?

Marcy Mutch
CFO, First Interstate BancSystem

$70 million-$80 million a month.

Tim Coffey
Analyst, Janney Montgomery Scott

Okay, great. Kevin, as we look out across this year, what is your expectation for absolute growth in the balance sheet in terms of total assets?

Kevin P. Riley
CEO, First Interstate BancSystem

Well, it all depends really on deposit growth. What we estimated and what I think Marcy alluded to is that, you know, earning assets should be flat for the year. What we're kind of modeling is that the investment portfolio will run down and loans will go up. Earning assets and the balance sheet will kind of remain flat, but we'll get better yields on our earning assets in total.

Tim Coffey
Analyst, Janney Montgomery Scott

Okay, great. Those are my questions. Thank you very much.

Kevin P. Riley
CEO, First Interstate BancSystem

Thank you.

Marcy Mutch
CFO, First Interstate BancSystem

Thanks, Tim.

Operator

Thank you. Our next question goes to Adam Butler of Piper Sandler. Adam, please go ahead. Your line is open.

Adam Butler
Analyst, Piper Sandler

Hey, everyone. Thanks for taking the follow-up.

Just, going into the interest-bearing deposit data. Do you guys have any guidance for 2023 as to where that is headed?

Speaker 15

Hey, Adam, it's John. I think as Marcy said in her prepared remarks, you know, at this point, the data assumptions versus the prior cycle, we wouldn't be changing those assumptions. We haven't specifically disclosed in the NII guidance that she gave what those interest-bearing deposit cost assumptions would be.

Adam Butler
Analyst, Piper Sandler

Okay, fair enough. Thank you.

Operator

Thank you. We have no further questions. I'll now hand back to Kevin P. Riley for any closing remarks.

Kevin P. Riley
CEO, First Interstate BancSystem

I wanna thank everybody for their questions. As always, we welcome calls from our investors and analysts. Please reach out to us if you have any follow-up questions. Thank you for tuning in today, and goodbye.

Operator

Thank you. This now concludes today's call. Thank you so much for joining. You may now disconnect your line.
