I would now like to introduce your hosts for today's conference, Mr. Marc Grandisson and Mr. François Morin.
Sirs, you may begin.
Thank you, Shannon, good morning to you all. Once again, this quarter, strong earnings from our mortgage segment offset the effects of catastrophe losses in our property casualty segments as Arch produced an annualized operating return on equity of 8.8% 10.7% for the 2018 fourth quarter full year respectively. Given the level of catastrophe losses across the globe in 2018, our results demonstrate again the value of our core principles of diversification, sound risk selection, underwriting discipline, cycle management. François will provide more commentary on our financial results in a moment, it's worth pausing for a minute to thank all employees at Arch who are committed to meeting the needs of our clients while producing superior returns.
Given the notable catastrophe events of the past two years, we will begin our discussion of market conditions with the January 1st renewal market in property catastrophe reinsurance. As you may have heard on other earnings calls this quarter, on average, property catastrophe rate increases at January 1 were positive but below expectations given the record level of insured cat losses that were reported in the past two years. Across the industry, loss-affected property accounts saw rate increases of 10% or more, while some property accounts in Europe were flat to down 5%. Hidden within the underlying property catastrophe industry average rate changes, there are some signs of tightening capacity within the retrocession and facultative markets. In many case rate levels relative to risk remain inadequate to deploy additional capital from our perspective.
At Arch, we believe that we enhance our odds of doing better than the industry average by allocating capital dynamically to areas with a better risk-reward trade-off, that disciplined underwriting and risk selection will remain at the core of what makes us and has made us successful. There is reason to believe that some rate improvement may occur throughout the year as the market absorbs the recent history of large cat losses. However, uncertainty with respect to both the expected amount of capital and the return on capital within the property catastrophe market make it difficult to predict where cat rates will be by year-end 2019. In the interest of time, I'm not going to review market conditions line by line, as I'm sure you have already heard about that on other calls this quarter, I will instead address the underwriting environment in general.
In our P&C segment, in some of our insurance lines, rate increases appear to be outpacing claim trends. As we have discussed in prior quarters, we continue to believe that the risk of claim inflation rising above its long-term trend is high, we remain cautious in our allocation of capital and in setting our loss picks. The modest improvements in rates are concentrated primarily in the short-tail cat-exposed business in the U.S. commercial auto and some areas of casualty. As always, we focus on the absolute level of risk-adjusted returns, not just relative rate changes. Turning now to our mortgage segment. The underwriting environment remains very attractive, with ongoing growth in our insurance in force producing strong increases in earned premium and will contribute to a future stream of earnings that is both stable and predictable.
For the fourth quarter, our USMI new insurance written, or NIW, was $16.7 billion, a 16% increase over the same quarter last year, the proportion of single premium business remained low at about 9% of NIW this quarter. Within our U.S. primary business, the credit quality of loans insured remains excellent, our key risk barometers are still at very healthy levels. To put this in historical context, our risk indices tell us that the current borrowers' credit characteristics are still substantially higher, in fact, by roughly a factor of two relative to the borrowers of the late '90s and early 2000s.
We have seen mortgages with greater than 95 loan-to-value grow slightly as a percentage of our NIW to about 16% in the fourth quarter, while credit quality, as indicated by FICO scores, remained high across our in-force book with a weighted average score of 743. As far as the new mortgage risk transfer programs with the GSEs, the so-named IMAGIN and EPMI facilities, we believe that these programs will continue to grow within our expectations, roughly at a modest 2% of total NIW for the market on an annualized basis. Briefly, with respect to our investment operations, higher yields available in the financial markets and growth in invested assets led to a 16% increase in net investment income in the fourth quarter over the same period a year ago. We remain underweight credit and interest rate, reflecting our cautious outlook.
Moving to capital management, despite our exposure to property catastrophe in 2018, we were able to deploy some of our capital towards expanding our distribution capabilities, deleveraging our debt, and repurchasing our shares. As you know, we recently closed on acquisitions in the U.S. and the U.K. that are expected to expand our distribution base. Volatility in the equity markets also gave us opportunities to repurchase approximately $100 million of our common shares in a quarter at attractive prices. As in all of our capital allocation processes, we employ a rigorous and disciplined assessment of available opportunities to deploy capital in order to generate long-term returns for our shareholders across all phases of the cycle. Turning now briefly to risk management.
For the past few years and continuing into 2019, our property catastrophe exposures remain at historically low levels, with our one in 250-year peak zone at about 4.5% of tangible common equity at January 1st. We have the ability and the capacity to deploy more capital to this sector if available returns improve to acceptable levels this year. For Arch clients and investors, our ability to increase our support in times of need is a significant benefit to the marketplace and a source, we believe, of long-term value creation for our shareholders. In our mortgage segment, our issuance of insurance-linked notes, known as Bellemeade securities, have significantly reduced our shareholders' exposure to the tail effects on our business from economic recessions and have paved the way for a significant reduction into our risk profile, despite growth in our insurance in-force.
With regards to PMIERs, as of December 2018, Arch MI's sufficiency ratio was 141% of the GSE capital requirements known as PMIER, as I mentioned. It also exceeds the proposed GSE revisions under PMIERs 2.0, which is to be effective on March 31st, 2019. With that, I will turn it over to François. François?
Thank you, Marc, and good morning to all. I'd like to give you some comments and observations on our results for the fourth quarter. Consistent with prior practice, these comments are on a core basis which corresponds to Arch's financial results excluding the other segment, i.e., the operations of Watford Re. In our filings, the term consolidated includes Watford Re. After-tax operating income for the quarter was $189.2 million, which translates to an annualized 8.8% operating return on average common equity and $0.46 per share. For the full year, our operating ROE stands at 10.7%, a solid result in light of the elevated catastrophe activity in the second half of 2018 and a pricing environment in the P&C sector that remains competitive.
Book value per share was $21.52 on December 31, a 1.7% increase from last quarter and a 6% increase from one year ago, despite the impact of higher interest rates on total returns for the quarter and the year. Moving on to underwriting results. Losses from 2018 catastrophic events in the fourth quarter, net of reinsurance recoverables and reinstatement premiums were $118.2 million, or 9.7 combined ratio points. These losses were predominantly the result of Hurricane Michael hitting the Florida Panhandle and the California wildfires, but we also felt the impact of other minor events across the globe. As for prior period net loss reserve development, we recognized approximately $74.4 million of favorable development in the fourth quarter, net of related adjustments, or 6.1 combined ratio points, compared to 4.6 combined ratio points in the fourth quarter of 2017.
All segments were favorable, led by the reinsurance segment with approximately $33 million favorable, the mortgage segment also at $33 million favorable, and the insurance segment contributing $8 million. This level is consistent with the third quarter 2018 results as we continue to benefit from significant favorable development in our first lien portfolio in the mortgage segment, where cure rates this year continue to be materially higher than long-term averages and expectations. The insurance segment's accident quarter combined ratio excluding cats was 98.3%, slightly lower than for the same period one year ago. Most of the improvement came from lower levels of attritional losses and acquisition expenses. The reinsurance segment accident quarter combined ratio excluding cats stood at 96.2%, compared to 103.2% on the same basis one year ago.
As we mentioned on prior calls, we tend to look at trailing 12-month analyses in order to assess the ongoing performance of our segments given the inherent volatility in the business that can emerge from quarter to quarter. The year-over-year comparison for the reinsurance segment is affected by a few notable items. First, as we mentioned on a previous call, our acquisition expense ratio last year reflected the federal excise taxes associated with a large internal loss portfolio transfer. Second, our loss experience this quarter was impacted by a large attritional casualty loss arising from the California wildfires. Third, we had a noticeable amount of reinstatement premiums and premium adjustments this quarter that benefited our combined ratio. Once we adjust for these variations, the underlying performance of our reinsurance segment remains strong this quarter.
The mortgage segment's accident quarter combined ratio improved by 1,410 basis points from the fourth quarter of last year as a result of the continued strong underlying performance of the book, particularly within our U.S. primary MI operations. The calendar quarter loss ratio of 2.1% in the fourth quarter of 2018 compares favorably to the 17.8% in the same quarter of 2017 due to substantially lower delinquency rates. Part of the difference is attributable to increased favorable prior development, which was approximately 320 basis points higher than last year. In addition, there was approximately $13 million, or 410 basis points of favorable development on 2018 delinquencies due to very strong cure activity in the period. The expense ratio was 20.5%, lower by 160 basis points than in the same period one year ago as a result of expense savings achieved.
I'd like to remind everyone that due to the nuances of purchase accounting, the amortization of our DAC asset should continue to increase in 2019 by an amount that is approximately $8 million higher on an annual basis than 2018 levels, increasing acquisition expenses. These results highlight the contribution to our pre-tax underwriting income from the mortgage segment, which remains strong this quarter. After allocating corporate items such as investment income, interest expense, and income taxes to each segment, the mortgage segment's contribution to our 2018 net income decreases to approximately 75% of the total after normalizing our results for catastrophic activity. Total investment return for the quarter was a positive 51 basis points on a U.S. dollar basis and a positive 83 basis points on a local currency basis.
These returns highlight the defensive, high-quality position of our fixed income portfolio and solid results in our alternatives portfolio in light of a volatile quarter across global financial markets. During the quarter, we continued to move away from municipal bonds and into corporate and government bonds due to relative valuations. The repositioning of our portfolio during 2018, combined with the reinvestment of shorter maturity bonds and other swap activity at higher yields, generated higher investment income year-over-year. We extended the duration of our investment portfolio in the quarter to 3.38 years, up from 2.94 years on a sequential basis as global economies weakened. Operating cash flow on a core basis was a strong $384 million in the quarter, reflecting the solid performance of our units.
The corporate effective tax rate in the quarter on pre-tax operating income was 16.8% and reflects the benefit of the lower U.S. tax rate, the geographic mix of our pre-tax income, and a 210 basis point expense from discrete tax items in the quarter. As a result, the effective tax rate on pre-tax operating income, excluding discrete items, was 14.7% this quarter, higher than the 9.9% rate last quarter. The difference from this rate to the numbers noted in our recent pre-release is primarily attributable to discrete items and a higher level of U.S.-based income, which triggered a true-up of tax accruals for the first three quarters of the year. As we look ahead to 2019, we currently believe it's reasonable to expect that the effective tax rate on operating income will be in the range of 11%-14%.
As always, the effective tax rate could vary depending on the level and location of income or loss and varying tax rates in each jurisdiction. With respect to capital management, we paid down the remaining $125 million of our revolving credit facility during the quarter, and we also repurchased 3.6 million shares at an average price of $27.11 per share and an aggregate cost of $98.2 million under our Rule 10b-5 plan that we implemented during this quarter's close window period. Our remaining authorization, which expires in December 2019, stood at $164 million at December 31, 2018. Our debt to total capital ratio stood at 15.5% at year-end, and debt plus preferred to total capital ratio was 22.5%, down 390 basis points from year-end 2017 and a full 620 basis points from year-end 2016 when we closed the UGC acquisition.
Finally, I would like to bring to your attention a change we are introducing in 2019 regarding our incentive compensation practices. As you know, equity grants made to employees had historically been awarded in May of each year. Starting this year, equity grants are expected to be awarded in the first quarter, subject to board approval. As a result, we would expect a small distortion in the timing of our operating expenses. The impact of this change, based on 2018 equity grants, is an expected shift of approximately $11 million to $13 million in operating expenses from the second quarter to the first quarter of 2019.
Two-thirds of that expense is expected to be reflected within our operating segments, with the remainder in corporate expenses and investment expenses. With these introductory comments, we are now prepared to take your questions.
Thank you. If you have a question at this time, please press the star then the one key on your touchtone telephone. If your question has been answered or you wish to remove yourself from the queue, please press the pound key. Our first question comes from Kai Pan with Morgan Stanley.
Thank you. Good morning. The MI segments continue to show very strong results. Is the 16% the underlying loss ratio a good run rate going forward, or you see continuing improvements from there?
The loss ratio has been very good and actually better than we had anticipated probably a year and a half ago. We have ongoing improvement in notice of default and curing rates. Right now, everything we're pointing to is much less than the long-term average, which would be 20%, I would think, overall cycle. Yeah, you can pick a new number, Kai. It's very hard to predict the future, but certainly we are in a very benign loss environment.
That's great. If you take out the large amount of reserve releases, the reported loss ratio below 10% have been around 10% or less for the last several years. At what point the regulator would just say, "Hey, the result is too good," and will be more focused on either pricing or competition could start to come in?
Well, I'm not sure what the regulators would do, but from our perspective, this is still a risky insurance product, like everything else is out there. What matters is really about the return. I would argue that even if you have a little bit higher than average return in the current environment, that probably more than makes up for some of the bad years that have occurred in the industry. We're not losing sleep over this. There's no commentary to the effect that the loss ratio is too high or too low. In fact, I would even argue that the new capital framework from the GSEs are leading us in a direction of still appropriate level of capital and return in the industry to make sure it's a solid framework for housing finance.
That's great. Hopefully, industry have a long memory. On the reinsurance side, the top line growth is very strong, even without the reinstatement premiums for the quarter. Could you talk a little about where do you see growth opportunity and what kind of return you're getting from those spaces? Are they higher than your existing business?
Yeah. The growth year-over-year is a little bit distorted. If you look at the last 4 quarters, it's more consistent. The growth that we've seen over the last 12 months continues to be areas that we've talked about before, international motor quota share, actually some commercial auto, we have some opportunities in there, and some workers' comp opportunities, of all things. There's a lot, and some property specific, property catastrophe related exposure in the reinsurance group as well. The growth that we're seeing in reinsurance is consistent with our fishing and looking around in the world for good returns, better risk-adjusted return if we can. Away from probably the more traditional commoditized reinsurance business. It's a little bit more bespoke than the rest of the things you would hear about in the marketplace.
Okay. Last one, if I may, on California. You have losses both from the property side as well as the liability side. How do you think the market going forward in term of pricing, in term of any sort of your risk appetite in the market on both the property side as well as the liability side for the utilities?
Yeah. On the liability side, it's a little bit easier to answer because these things almost, there's a lot of question mark in the industry as to whether these are insurable and at what level and at what price. As you know, it's not a big market. Currently, the player that's been tagged or has been identified as being liable for that loss is going through a lot of difficult times. We'll see how that develops, which currently developing as we speak. This is still a very small market, right? In the broader scheme of things. As far as the property is concerned, it's really uncertain. As I said in my opening remarks, the capital supply is still plentiful.
There were talks at the beginning, Kai, maybe that's what you allude to the fact that there might be some changes to the modeling of California wildfires, it's still very early. People are still trying to figure out what they have and what it means in their modeling. As you know, it's a little bit isolated, in fact, right? It's isolated to one area of the country, and people have a way to manage a portfolio and deploy capital in other areas. It's a very hard question to answer because we don't know what the supply of capital is going to be by mid-year. Logic would dictate it should go up to some extent, but we'll see what happens.
Great. Well, thank you so much, and good luck.
Thanks, Kai.
Thank you.
Our next question comes from Geoffrey Dunn with Dowling & Partners. Your line is open.
Thanks. Good morning.
Hey, Jeff.
I was hoping you could comment a little on the ILN market. Now that just about all the MIs are using that market and indicating that they plan to use it on a recurring basis, are you seeing any change in terms, conditions, appetite, or is it as steady as it was over the last few years?
No. What we've seen, there's actually no indication that it's weakening. We see tremendous investor appetite for the product. As you know, the GSEs really started, and we were in there as well as the sole MI that was accessing that market in the last year. Most of the others have jumped into, I call it on the bandwagon. Investors now have the ability to, when they do their research-
They do the analysis. They feel it's something that's repeatable. They can access that type of product not only through us, but also through some of our competitors. As far as we can tell, there's still tremendous appetite for the product. It's expanding a little bit. Getting some of our instruments rated has also helped. We see that as something that there's nothing on the horizon that suggests that we won't be able to execute on it.
To add to this, Jeff, I would also argue that the spreads are not widening. At least we don't see any indication of spreads widening. This appears to be a stability of pricing expectations in the product as well.
Yeah. Recommending some volatility here and there. In the long term, we think yes.
Yeah.
Spreads have been very stable.
Yeah.
It looks like you took another dividend this quarter. Should we take that to assume that the regulators are also comfortable with this market and view it as true capital relief?
Absolutely.
Okay.
We argue it's even better than traditional reinsurance because we have the cash on hand, so it's collateralized. From that point of view, they agree with it, they accept it, then they should be even happier than just other forms of capital. Aside from just a traditional equity.
Okay. Then a follow-up on new notice development. Is the company's book reaching an inflection point where even though the newer vintages are very high quality and outperforming, but the book size is obviously, and the ceasing is going to drive decent new notice levels. Are the more recent vintages now exceeding the benefit of the runoff of the 2008, meaning that we should see on average new notice growth going forward?
I think we will at some point. I'm not sure that we've crossed it yet. It's very hard for us to see and to predict that. You're right. Over time, we would expect as the 2009 and prior, or the 2008 and prior is rolling off, yeah, we would expect that. I'm not sure that we are there yet.
Okay, great. Thank you.
Thanks, Jeff.
Our next question comes from Joshua Shanker with Deutsche Bank.
Good morning, everybody.
Morning.
I was noticing the trend, it's not so surprising that the proportion of new policies being written on the mortgage segment that are coming from refis get smaller and smaller all the time, now down to 5%. Is there any difference ultimately, you think, in the quality of a refi mortgage versus a new mortgage? I guess you know the refi mortgage is better, at least the market knows them better. How should we think about that?
Yeah. Clearly, there tends to be at the margin better quality for the refinance market. It's clearly not a target market for the MI market, right? Broadly, you are right. In terms of what pertains to the MI market, our penetration for origination of MI of mortgages in the refinance is 5%-6%. It's very small. The market that we are targeting that is really our bread and butter, if you will, is the purchase market. That's still pretty healthy. That's really what we've been focusing on. Having said all this, if you look at historically at the blend of the FICO, the blend of the DTI, it's been fairly consistent, and I think that speaks to there's not that much of a difference between the credit requirements, whether you refinance or whether you purchase.
Not to belabor too much on the refi.
Sure
If you are writing the MI on a refi mortgage, were you the MI on the mortgage it's replacing?
Not necessarily, because you could be refinancing with a different financial institutions, and at the end, that institution may have a different agreement with a different MI. Not necessarily.
Okay. Switching gears on the wildfire liability. Look, obviously, that was a difficult loss two years in a row. The pricing might have been adequate to take that. A lot of times, though, in certain markets, the market really isn't big enough to give you a payback no matter how good the pricing is. Do you think you'll get a chance to write wildfire liability this year? Is the market sizable and attractive enough to make it a worthwhile business to write on a multi-year basis?
Yeah. The answer is yes to all of those. I think in general, we don't think of either being in the market or not based on size. I think what it means to us is we would put in relation to the market size our commitment to that marketplace. The interesting in reinsurance, Josh, is you have to forget last year and look forward. Because if you look back to what the losses you have, you don't have to make the money the way you lost it. That's clearly one thing that we always live by every day. Certainly, every time a proposition comes to us, provided we have the right information and the right perspective on the loss, if it's a profitable thing, we would do it regardless of the size of the market.
The only thing that we would do is rightsize our commitment to that specific market based on its size relative to the broad capital base of the company.
Is that a mid-year renewal?
I believe so.
Well, that one was a multi-year model.
That one's a multi-year. Yes. Correct. Sorry. Yes.
Okay. Thank you.
Thanks, Josh.
Our next question comes from Mike Zaremski with Credit Suisse. Your line is open.
Hey, good morning.
Morning.
First up, François, in the prepared remarks, you made comments about actions you've taken on the expense side to improve the ratio, the trend has been improvement over the last year or so. This quarter came in I think, better than expected. Is any one-time items in there, or is that improvement somewhat sustainable?
Well, are you referring specifically to mortgage?
Yeah.
Yeah. Well, mortgage, we acknowledge internally that it's been two years since the acquisition, we're basically complete with the integration. Hopefully, you guys will remember that we told you it'd be a journey. It would take a couple of years to fully integrate the two operations. We're at the stage now when you compare, obviously, year-over-year, Q4 2017 to Q4 2018, we just realized more savings in technology, in people, et cetera. I think we're kind of there. There's also a bit of seasonality that comes into play. We're truly in a good spot in terms of where we think our expense base and especially operating expenses will be going forward.
Okay. Got it. Sticking with the mortgage segment, Marc, you made an interesting stat you made in the prepared remarks about mortgage credit quality being approximately, I think you said, two times better than pre-crisis levels. Maybe you can further elaborate on what's behind that viewpoint.
We have internal proprietary credit analysis evaluation. You could also look at some things that are published by outfits such as the Urban Institute. You will look at the relatively credit quality based on an index looking at the late 1990s, early 2000, factoring income, credit score, and all these various aspects of a credit worthiness of a borrower. When you run it through the grinder, if you will, and you come up with a number at the end, that number is half of what it was back in the late 1990s and 2000. This is made on a comparable basis, long stand to be as apples to apples as can be.
Okay. It's interesting because, yeah, you know qualitatively there's a lot of reasons why credit quality is most likely better. It's interesting that you're trying to quantify it, and it's helpful.
Yeah. Very, very much so. Yep.
I guess follow up on that, and maybe I'm missing this in the supplement, I can get it offline, but what percentage of the mortgage insurance portfolio has reinsurance protection, and what's the average duration of that reinsurance protection?
That's a good question. I don't have the numbers right in front of me, but it's.
A couple of things. 50% quota share with AIG.
Some years.
14 through 16. You have Bellemeade. We have about $1.1 billion of outstanding limits on the Bellemeade that covers-
About two-thirds.
About-
Two-thirds
two-thirds of our portfolio has reinsurance against it. Thank you.
Okay, the duration of the Bellemeade transactions, roughly?
Well, they're 10-year transactions, right? They're all a bit different. Some have features where we try to have the coverage be in force for a bit longer, but I would say about five years is probably something where as we keep rolling off, we're adding new ones. I think that should remain pretty stable as we move forward.
Right. Yep. Thank you very much.
Thank you.
Our next question comes from Elyse Greenspan with Wells Fargo. Your line is open.
Hi. Yes. My first question, you guys said, if you normalize for cats, that you're seeing mortgage, I think you said about 75% of earnings. I guess, what do you guys view as your normal cat load since your PMLs have come down, right, but we're coming off of 2 years of pretty high cat losses?
Well, the cat load roughly is about $30 million a quarter, $30 million-$35 million a quarter. That's kind of where we've been running at the last couple of years. These numbers that I quoted, really all we do is replace effectively the actual cats with the expected or the cat load. Hopefully, that answers your question.
Okay. When you give us the tax rate guidance for the coming year, you're also assuming that cats fall within that normal level, correct?
Correct. Yes. That's a full year forecast with an expected cat year, which as you know is usually not the case. It's either lower or higher, but yes.
Okay. On reinsurance, you guys seemed to kind of be cautious and balanced in terms of what might happen at the mid-year renewals. Marc, how much would you say you need rates to go up for Arch to want to materially write more cat business? If you want to talk separately about what you might want to see at April 1 versus June 1 and July 1 in Florida.
I guess I could tell you a lot more, but that's not going to get you what you want. I think if you look back, Elyse, at one of my comments about six quarters ago, looking back at the characteristics at the time, the numbers were 35%-40% to really start getting us to the risk-adjusted return that we believe is appropriate. We've had since maybe 10%-12% rate increase, that tells you we're probably 25%-30% still short of rate change to really get there. Again, I want to caution everyone that is listening to this saying that 2025 is not going to come across the board all at once. There's some pockets that need a bit more than this, some that need a little bit less than this.
That gives you a flavor for how much more we believe we need to get us to start going the path of deploying more capital.
Okay. Thank you. That's helpful. On the mortgage side, as some of your competitors have adopted risk-based pricing models as well, have you started to observe a broader impact on the market? Kind of anything changing there?
Nothing yet. It's still very early. We'll have to wait and see how it's rolled out, how it's actually developing in the marketplace. I would say that for everybody's benefit, our risk-based pricing was created back in 2011. This is our UGC, well, now our USMI operation, and there's a lot of things that need to happen to have a run rate. We're going to have, most likely, some bumps along the way. Our competitors are going to be trying things and figuring out things that work and don't work out as well. We're bracing for it, the key thing from our perspective is we're keeping steady in our grid, in our risk-based pricing, and we're going to take whatever market, however they react, we'll be the beneficiary or we'll lose some business because it's mispriced based on our own.
It's too early to tell, Elyse. It's going to take a while.
Okay, great. There's some concerns on the outside in terms of recession and impact on credit and how that might play out late this year, maybe into 2020. As you guys obviously alluded to credit being really strong relative to past cycles, what would you be paying attention to to see the potential turn in the credit cycle?
Right now, I think if you look historically at what went wrong, certainly the credit quality, the credit worthiness of the borrower is extremely important, right? What happened historically that really created the issue is the product development. If the product, like the low doc, no doc, Alt-A, all this stuff comes back to the market, this is what we'd be worried about. Of course, the other macro thing that could impact everything is the housing price depreciation across the economy. The one thing that we're not worried about, the reason why we're not so worried about right now is because there is a shortfall on housing supply, and it's been there for quite a while. Everybody's predicting smaller price increase in house prices, but still positive for the next two, three years. A recession could probably put a bump on this.
If you look at it historically on some recessions in the past, we had times when house price increased by 1%. The only time it went down, guys, for your benefit, and that's actually very useful to know, is only in the '07, '08 crisis. For the last 45 years, the house price index, despite having gone through five, I think, different recessions, only came down once. The price index came down once. The product is really the problem, Elyse, and we don't see anything yet.
Okay. Thank you very much. I appreciate all the color.
Welcome. Thank you, Elyse.
Thank you. Our next question comes from Meyer Shields with KBW. Your line is open.
Great, thanks. Marc, in your introductory comments, you noted not just that loss trends could get worse, but they could resume above average levels. I was hoping you could clarify why that is a concern right now.
We're seeing some changes in some of our submissions and some of our data. It's still very early signs, and it's really anecdotal. Sometimes anecdotal, sometimes actually real. We're seeing loss trend picking up in certain areas, and we believe it's only a matter of time before it starts spreading to other lines of business. Meyer, as you know, we're students as well of the industry, and the CPI is about 1.8, 1.7. As I mentioned that in prior calls, the inflation on the insurance inflation is typically running ahead of it by 150 to 250. I would expect a trend that could be recapturing, having a very vibrant economy, exposure growth, and more friction in the marketplace. We would expect those to generate more losses.
The reason we're putting that out, Meyer, is because I want to put that in the perspective of the price increase that we talk about on average being 200 or 250 or 300 basis points. It just doesn't make for a lot of margin of safety as you go about analyzing how you allocate capital between lines of business. As you know more probably than I do, is when you write a business, an insurance policy, it takes years for you to really find out how bad or how good it's going to be. We tend to take a more cautious approach to it.
Okay, that's very helpful. Thank you. Quick modeling question. With the recent U.S. nuclear acquisitions, are those going to produce any appreciable change in the expense ratio?
Short term.
Both acquisitions were the mortgage segment. I would say that the expense ratio, yes, no question that in one of our acquisition in the U.K., maybe a bit of integration expenses that will have to be reflected. All in all, given that the U.S. one, it's a partner, it's a business that we've done business with for many, many years. That should not really impact the expense ratio. The final thing which you'll see in the 10-K is that will certainly trigger a slightly higher intangible amortization expenses that start coming through in 2019.
Okay. That's segment or corporate?
The intangibles is all one number altogether. When we finish up our analysis and we publish a 10-K in a couple of weeks, you'll see the slight changes from what we published a year ago, which was primarily UGC related.
Okay, fantastic. Thank you.
Thank you.
Thank you. Our next question comes from Brian Meredith with UBS. Your line is open.
Hey, guys. Seth Rosenberg here for Brian. Thanks for taking my questions. Got one for you. If you look at the insurance segment, large losses improved versus last year. If you look back at last year, I think you had called out 2.2 points, which was elevated at the time. If you kind of just take this quarter in a vacuum and not the comparison, would you say that large losses were better or worse in line with expectations? I ask because so many companies are calling out a higher frequency and severity of large losses. Just trying to get a feel if there's something in loss cost there that concerns you.
Right. Our insurance group adds some lumpiness to it, right? Not as much as reinsurance, for obvious reasons, there's still some quarters that are above average or below average. This quarter was sort of an average quarter for us in terms of large risk loss or non-attrition loss, as they call it. We have a hard time, for everybody's benefit, slicing and dicing the losses in so many different sections. At the end of the day, we are providing insurance coverage for all kinds of losses. What you're seeing right now is sort of what is our loss pick inclusive of all the things that could happen in our portfolio.
Got it. Nothing particular to construction costs or labor that really stuck out and drove severity?
Nope. If anything would have happened there, it would be already factored in our loss ratio pick.
Got it. Thank you.
Yeah.
Switching over to mortgage. Last year, the delinquency rate kind of spiked up due to the storms in the third quarter. No reason to believe that we would see a similar dynamic in the first quarter from Hurricane Michael and the wildfires?
We looked at this, and we also thought about the government shutdown, which was on the horizon. There's certainly GSE rulings that prevent us from these potential delinquencies developing into claims. Going back to the hurricane, 2017 was slightly different in the sense that both, in particular Hurricane Harvey.
Where the flooding was persistent for a number of weeks. It was more damaging than Hurricane Michael that came in and through, and didn't really have an elongated timeframe to the event. At this time, we don't think there'll be any spike in our delinquency from the cats.
Right. As far as the government shutdown, Trump signed up something at the end of January just releasing back pay. That should be.
Right
should go a long way to alleviate any of our concerns there.
Great. That makes a lot of sense. Thanks, guys.
You bet.
Our next question comes from Amit Kumar with Buckingham Research. Your line is open.
Thanks. Good morning. Just two quick follow-ups, if I may. The first question goes back to the discussion on wildfire casualty losses. I just wanted to understand a bit better, if the utilities numbers change or if there is any other development, does your current number remain static, or how is that reserved? Maybe help me explain that a bit more.
Well, from our point of view, it's fully reserved. There's no adverse development that we can see on this particular claim. Yes, it might with bankruptcy court, and things could change, but if they change, we think they'll be in our favor. They'll reduce the number. We've taken the most conservative view that we can think of at this point, and we'll see how things play out.
What is the size of this book for you, in terms of percentages or any way to sort of think about it?
Well, it's really a one-off, right? It's not a book per se. We have a small unit that focuses on these kind of bespoke transactions. Typically, there's a lot of them that are property-type deals. This one was a casualty deal as well. As you know, these deals come to the market infrequently. You don't know where they're coming. You look at the opportunity, you assess the risk, you make a decision on the pricing, and if the risk-adjusted returns are there, we try to participate. At this point, it's not really a book in itself. It's an amalgamation of policies that we write on an ad hoc basis.
Amit, the one thing that's interesting with this one, because it's such in the high price to get out of breath, you don't hear about the 98 others that worked out to our favor. Let's leave it at that.
Yeah.
No, that's a very fair point. I guess the only other question I had was going back to the discussion on buyback, and I think in your opening remarks, you talked about the volatility in the markets giving you an opportunity. The buyback obviously was higher than my numbers and the Street numbers. In the past, we used to talk about a matrix, and in fact, there used to be a matrix on your website, which I was having trouble finding. Are we still utilizing that payback matrix, or how should we think about future buybacks?
Well, yes. The matrix that you're referring to is still the starting point of our analysis. The question that comes up often from many of you on the phone is, with the growth in the mortgage segment, does that matrix or that view change?
Yes, sir.
The answer is it does, but it's not black and white. What we like, and we told everyone before about the mortgage segment, is that we like the visibility and the predictability of the earnings stream that it gives us. The three-year payback that we've targeted in the past, we have a view that, yes, maybe we'd be willing to extend it to four years, to five years, who knows? That's always considering all the options that are available to us. We talk about acquisitions, we talk about reducing our leverage. There's all these aspects of capital management that come into play. Hopefully that answers your question. The grid is still there, but we have some flexibility around it.
Got it. That's what I was looking for. That's all I have. Thanks for the answers, and good luck for the future.
Thanks, Amit. Appreciate it. Thank you.
Our next question comes from Yaron Kinar with Goldman Sachs. Your line is open.
Hi, good morning. Just one quick one. Could you break out the cat losses by event?
Well, we typically haven't done that. The number you have in front of you is both for wildfires and Michael, predominantly with a few small others as well.
Okay. Maybe one follow-up then. As you look at the market into 2019, would you expect opportunistically to grow the property catastrophe book or the property catastrophe exposure?
Like I said, if we get the rates that we think are warranting an increase, we will increase. We have increased some property exposure in the last quarter. There were some opportunities to do it. As we said, it's just not a broad-based market opportunity, we are always on lookout for specific transactions or relationships to really take advantage of that. We're present on Front Street. We're open for business, as you know, we will do it if it's there.
Okay. Thank you very much.
Thanks, Yaron.
I'm not showing any further questions. I would now like to turn the conference over to Mr. Marc Grandisson for closing remarks.
Thank you very much, everyone. It was a good year. Appreciate your time, and happy Valentine's to all of you guys.
Love you all.
Thank you.
Ladies and gentlemen, thank you for participating in today's conference. This concludes the program. You may all disconnect.
