Good day, ladies and gentlemen, and welcome to the third quarter 2010 Arch Capital Group earnings conference call. My name is Jennifer and I will be your operator for today. At this time, all participants are in listen-only mode, and later we will conduct a question-and-answer session. (Operator instructions). As a reminder, this conference is being recorded for replay purposes.
I would now like to turn the conference over to your hosts for today, Mr. Dinos Iordanou and John Hele. Please proceed.
Dinos Iordanou - Chairman, President and CEO
Thanks, Jennifer. Good morning, everyone, and thank you for joining us today.
Our performance for the third quarter was acceptable as we continue to operate in a challenging environment, both for us, but also for our customers. Our annualized return on average common equity was 12.3%, which in our view is reasonable for current market conditions. These returns were not negatively impacted by major cat activity and benefited from favorable prior-year reserve development. The New Zealand earthquake was a minor event for us and was contained well within our expected cat load for the quarter. We continue to estimate that under current insurance market conditions and current investment environment, we are achieving on a normalized basis a 9% to 10% ROE on business written for the 2010 underwriting year.
This return is realistic given operating and financial market conditions, even though it does not meet our long-term targets. In our most important measure for creating shareholder value, which is our ability to increase book value per share, we had an excellent result. A very good total return on our investments, acceptable operating returns on our underwriting activity and share repurchases helped increase our book value per share to $89.24, which is up 22.2% from year-end 2009, 8.7% from June 30, 2010, and 28% from a year ago.
From an underwriting point of view, we achieved a 90.4 calendar year combined ratio, which in our view is 6 to 8 points better than a normalized accident year combined ratio, which we estimate to be in the 97% to 99% range.
Cash flow from operations remained healthy at $267 million, even though our current book of business is declining and our prior year's book is maturing. In addition, our mix of business have moved more toward short-tail lines than in the past, which have faster claim payment patterns that affect cash flow.
From a production point of view, our gross written was down 11% and our net written premiums were down about [10]%. Our reinsurance operations were down 19% as they continue to pursue a strategy of reducing writings in long-tail lines while moving to more XOL contracts on property business and property cat business. 90% of the reduction in volume is attributable to casualty lines as a result of the difficult market conditions we are operating under.
Our ratio of pro rata to XOL business is now 43% to 57% as compared to 52% to 48% as of a year ago. The actions we have taken in our reinsurance business, which I just referred to, had an exaggerated effect on written premiums but a modest impact on overall profitability and a beneficial effect on returns.
On [cover] share contracts, terms and conditions continue to remain basically stable with most of the rate erosion occurring at the primary business level. Our insurance group continues to emphasize and move their book to less volatile lines and to reduce their writings in the long-tail lines. Over the past five years our net written premium for short-tail lines in the US and Canada increased by 50%, while our long-tail business decreased by 16% with casualty leading the way with a reduction of 70%. Despite these actions, due to the challenging market conditions that exist, margins continue to be under pressure. Rate changes in the US ranged from plus 3% to minus 10%, depending on the line of business and size of account, except for offshore energy, where increases were in the 20% plus range.
In the aggregate across all of our insurance lines, rates were down approximately 3% for our book of business, which was the same level of rate change recorded in the second quarter of 2010.
Our capital management philosophy has not changed. We intend to continue to return excess capital to our shareholders as long as we do not see attractive opportunities to deploy it in our business. As you can see, share repurchases for the third quarter were light as we are more cautious with our capital position during the hurricane season. Since the inception of our buyback program, we have invested over $2 billion in our own shares, which is 1.5 times the amount of common equity we raised from shareholders over the past nine years. This reflects a culture of shareholder focus that we are very proud of.
As of September 30, we still have a $487 million available authorization for share repurchases and expect to return to a more normal pace of repurchases in the fourth quarter.
Before I turn it over to John for more color on our financial results, let me share a few thoughts on our CAT writings and PML aggregates. As of July 1, 2010, our one in 250 PML from a single event was $809 million, or 18.4% of common equity, up from $797 million at July 1, 2010. This PML is for the Florida Tri-County area and is our largest PML area, as expected. Our Northeast wind area P&L stands at $756 million, up slightly from $733 million as of July 1, 2010. Both zones are significantly below our 25% of equity self-imposed limitation.
With that, I'm going to turn it over to John for more commentary on our financials. And after John, we will open the call for your questions. John?
John Hele - EVP, CFO and Treasurer
Thank you, Dinos. For the 2010 third quarter, property and other short-tail lines represented approximately 49% of our net premium volume compared to 45% in the 2009 third quarter. On a consolidated basis the ratio of net to gross was 77% compared to 78% for the same period a year ago. Our overall operating results for the quarter reflected a combined ratio of 90.4% compared to 90% for the same period in 2009. The third-quarter loss ratio for 2010 included $24 million or 3.9 points of current accident year cat activity compared to $5.3 million or 0.7 points in the 2009 third quarter. The 2010 third-quarter cat activity was primarily related to the New Zealand earthquake, mainly in the reinsurance segment. As of the end of the 2010 third quarter, the provision for the first quarter cat events, which included the Chilean earthquake, did not change materially. Moreover, both the insurance segment and the reinsurance segment experienced a lower level of attritional loss activity compared to a year ago, primarily in the property lines of business.
The 2010 third-quarter combined ratio reflected 5.9 points or $37 million of estimated favorable development net of related adjustments compared to 7.7 points or $56 million in the 2009 third quarter. The prior-year development in the third quarter of 2010 reflected favorable development, primarily in property and other short-tail lines as well as the reinsurance segment casualty business and the insurance segment executive assurance from earlier years. The current accident year loss ratio excluding large cat events reflects the lower level of attritional loss activity previously mentioned as well as the overall impact of the reduced writings of casualty business that Dinos mentioned. The 2010 third-quarter expense ratio of 33.1% was 3.7 points higher than a year ago, primarily reflecting lower premium volumes as well as changes in the mix of business and changes to the ceded reinsurance structures in the insurance segment.
On a per-share basis, pre-tax net investment income was $1.77 in the 2010 third quarter compared to $1.60 for the same period a year ago and $1.70 in the second quarter of 2010. This growth reflects the accretive impact of the share repurchase program more than offsetting lower reinvestment yields. Total return for the investment portfolio was 3.61% in the 2010 third quarter. Excluding foreign exchange, it was 2.94% in the quarter. The net total return benefited from lower interest rates as well as from the devaluation of the US dollar against many global currencies. However, the impact on book value was offset by a net $65 million increase due to liabilities for currency movements reflected in the income statement. The duration of the investment portfolio increased slightly to 3.11, up from 2.90 at the end of the second quarter of 2010. The increase in duration during 2010 reflects a slight change in yield curve positioning which benefited the total return, as interest rates have fallen.
However, we are carefully monitoring the potential impact of the quantitative easing, now known as the QE2, which is expected to start in the fourth quarter and we have maintained our ability to quickly, if required, due to rising interest rates. We continue to be conservative with regard to the credit outlook and maintain a AA+ average credit quality on the portfolio.
Our balance sheet is conservatively positioned with total capital of $5.1 billion at September 30, up from $4.8 billion at June 30, which reflects the limited share purchase -- the limited share repurchase activity during the quarter, the operating earnings and the overall investment results. The cumulative share repurchase since 2007 added $0.70 to the diluted operating earnings per share or 2.8 points to the ROE. Our debt plus hybrids represent approximately 15% of our total capital, well below any rating agency limit for our targeted rating.
Last quarter we gave you a slightly wider range of estimated excess capital to reflect a growing percentage of capital reflected in accumulated other comprehensive income, known as AOCI. To be more specific this quarter, as of September 30, we estimate that, including AOCI, we hold approximately $900 million to $1.1 billion above our targeted capital level, based on current rating agency models with an appropriate buffer. However, if we exclude AOCI, our excess capital position would be $500 million to $700 million. Our liquid cash, short-term investments and US treasuries represent about 23% of our investable assets.
With these comments, we are pleased to take your questions.

Jay Gelb, Barclays
Jay Gelb - Analyst
Thanks, and good morning. I just wanted to follow-up on the excess capital position. In terms of what Arch would consider the available excess capital in terms of deploying that into share repurchases, should we be thinking about the $500 million to $700 million range, ex-AOCI?
Dinos Iordanou - Chairman, President and CEO
Yes, I think that's more of a safe number to -- because OCI can move and it has volatility, especially in the market that we are operating in and the economic environment that we're facing. So if things stabilize, we might change our view. But, for the time being, we don't -- it's that old expression, it's don't count your eggs until they hatch. So, that's our approach to it.
Jay Gelb - Analyst
Right, now that doesn't assume any further retained earnings going forward, right? So (multiple speakers)
Dinos Iordanou - Chairman, President and CEO
That's correct, that is correct. That's on a static number as of the end of the third quarter of this year.
Jay Gelb - Analyst
Right, so how quickly should we think that Arch might look at deploying that excess capital into buybacks?
Dinos Iordanou - Chairman, President and CEO
Well, it will depend as where our share price is, and where the market is going, and based on those two parameters, and our ability also to operate within the Safe Harbor in share repurchases, it will determine as to how much we can do on a quarterly basis.
Jay Gelb - Analyst
Right, and the other thing I just wanted to follow up on is the reinsurance growth. The premium year-over-year declines, my numbers are right around 40% on a gross written basis in reinsurance in the fourth quarter of 2009. So my sense is that you're lapping an easier comparison for the fourth quarter of 2010. Is that the right way to think about it? So (multiple speakers)
Dinos Iordanou - Chairman, President and CEO
No, you can't -- you know, in reinsurance, we look deal-by-deal, we look at the market, we -- the major shifts on our book on the reinsurance -- I'll give you the big picture, is that at the zenith of our reinsurance activity where it's back in '04-'05, the reinsurance group was about $1.6 billion. We're about -- we track it on activity of close to half of that, as of today. But, more importantly, the reinsurance group is mostly property today, and property cat. 70% of what we do is in that territory. And we still view the property/property cat area attractive.
So, I wouldn't just try to see year-over-year comparisons, because don't forget, a lot of the casualty business we had in '09, it was already gone in '09, from '08 to '09, so the '09 to '10, it might be totally a different comparison for the fourth quarter.
Jay Gelb - Analyst
Right, so I guess what I'm saying is, should we anticipate the overall premium volume of the reinsurance business declining even more, or now that you're down to (multiple speakers)
Dinos Iordanou - Chairman, President and CEO
No, it's probably -- that -- we don't give guidance, so I'm not going to guide you on an answer, but let me give you the parameters. The drastic reduction in our premium volume in the reinsurance group has been predominantly casualty, long-tail lines, and some professional liability. A lot of those reductions already have happened, so we're down to very little remaining. So, the pieces that remain is business that we like. As a matter of fact, some of them we're growing, such as credit or some others that we believe the profitability meets our target requirements.
So, it's not an easy comparison for us, because we will look at the merits of our expiring book and make those determinations over the next three months, and probably the reductions will be less than what we had a year ago because the business that we have is business that we like and we don't see significant price erosion going on.
Jay Gelb - Analyst
Right, and the mix shift has already occurred?
Dinos Iordanou - Chairman, President and CEO
The mix shift already occurred. That's correct.
Jay Gelb - Analyst
Okay, thanks very much.

Beth Malone, Wunderlich Securities.
Beth Malone - Analyst
I have a question on your tax situation. We've heard constantly here that it's, people are looking at changing the tax status for companies located in Bermuda, and some companies have relocated. What is your strategy towards that, and are you considering relocating?
Dinos Iordanou - Chairman, President and CEO
We are happy where we are. I can't predict what the US Congress will do with tax policy for companies in the US, but let me remind you we are a foreign corporation with US subsidiaries. It might affect some of the activity we have with our US subsidiaries. But it's very hard to shadowbox a shadow. At the end of the day it depends what happens and then we will take action, depending on that activity.
For us, as we've said many times before, the [neo] bill that gets a lot of publicity will have limited effect in what we do because there is too many moving parts. Excise taxes might go down and underwriting profitability tax might go up. But depending on the current market position, probably the effect on the overall tax for the Company will be insignificant.
Beth Malone - Analyst
And then one other question on your investment portfolio. Would you be comfortable increasing your exposure to alternatives and other more, I guess you would call them aggressive type investments, because you are well below what the rating agencies would be comfortable with already? And with the yields so low on traditional type of fixed income securities, what is your strategy for that?
Dinos Iordanou - Chairman, President and CEO
Well, let me give you more of a philosophical answer, and then I'll turn it over to John to tell you a little more specifically as to how we think about this.
At the end of the day, we never want to be aggressive in the investment strategy that we have. We view investments as a necessary part of what we do in our business, and of course when you have excess capital and your primary business, which is the underwriting business, is not in the best part of the cycle, you look to try to enhance that. But we are only going to enhance it by taking a conservative, measurable investment risk. People who buy our stock, our shareholders, they don't make the determinations to own Arch because we are brilliant investors. I think we are very good investors and we like to be well above average in that, but in a conservative fashion, and we want people to buy our stock because they think we are good underwriters and we can make very good underwriting decisions. And that's the philosophy that guides us as to what we are going to do with $12.5 billion of investable assets in tough times like now that we are in the downcycle.
John, do you want to add anything (multiple speakers)?
John Hele - EVP, CFO and Treasurer
Sure. And we mentioned it in the press release, as well as you'll see it in the investment side under investable assets, we are increasing our -- they are labeled other investments by accounting in credit funds and some equity securities. Credit funds are a little over $200 million, about $200 million in equity securities and others. These are a series of portfolios that we're looking at in natural resources, in some basic equities, some emerging market debt. These are still under 3.5% of the total portfolio, but we think these offer some nice attractive opportunities right now relative to other opportunities that are available to us. So, as Dinos said, this will always be quite a conservative portfolio across the board in total, but we are just taking this opportunity now to pick some spots to play.

Vinay Misquith, Credit Suisse.
Vinay Misquith - Analyst
Was this quarter's results favorably impacted by some extraordinarily low level of large property losses?
Dinos Iordanou - Chairman, President and CEO
Yes. It was a quarter that, both on the reinsurance side and insurance side -- and it wasn't just property, I think it was aviation, too, and short tail-related. The attritional activity was better than expected, and especially from large type of losses. And in a company like ours, we write a lot of these specialty covers, you can get quarters that behave as such.
John Hele - EVP, CFO and Treasurer
Yes; I think we've mentioned this on prior calls, that as our book is shifting more to short-tail lines of business, property and other things, it's going to be a little more volatile from quarter to quarter in terms of what happens. It's -- if a building burns down or it doesn't, and that's flow-through.
Vinay Misquith - Analyst
That's great. And did I hear you (inaudible) said that the normalized or combined ratio with cat would be about 97% to 99% ex-favorable development?
Dinos Iordanou - Chairman, President and CEO
Yes. That is -- and normalized cash flow. So if you have -- if you take normalized cat and eliminate favorable reserve development from prior years and you look at the business you are writing today, based on the investment climate that we have, new money invested, we believe that the ROE is in the 9% to 10% range and the combined ratio is somewhere between 97% to 99%, combined ratio.
Vinay Misquith - Analyst
And [I note] rates coming down, do you see that (technical difficulty) declining to the mid-to high-single digits next year?
Dinos Iordanou - Chairman, President and CEO
Well, don't forget, I can't predict what's going to happen next year. Don't forget, our mix continues to change. We try to move to lines of business that give us better returns. So not trying to predict the mix, it's very hard to answer that question. Not every single line of business is experiencing price reductions. Some lines have stabilized, and they are in the slight positive from a rate point of view. Of course, we have a lot of lines that are still in the negative and you have trend working against you. And that direct you to continue changing your mix of business. And as you've seen, some of our areas of growth came from unusual or areas that we found more profitability in the last year or two, and then we took advantage of those opportunities.
Vinay Misquith - Analyst
Sure, and one last question -- could you comment on frequency and severity trends, please?
Dinos Iordanou - Chairman, President and CEO
The frequency trends continue to be favorable. Severity is starting to stabilize and inching up a little bit. But those trends, they are positive in nature. The big question there is, do you believe that they are going to continue or do you think that they might change in the future? That's a judgment different managements and reasonable people can get to different conclusions. Some people might be more optimistic than we are, and they will think that this thing will continue forever. And others, they say, well, enjoy it for the year that it happened. It's going to get to more normalized over the future.
We watch those numbers. Our actuaries spend a lot of time on looking at frequency and severity trends, and we do it by (inaudible) family to each one of our product lines. But in general, the environment is still good. From that perspective, from the frequency-severity perspective.
Vinay Misquith - Analyst
Has frequency now stabilized at very low levels?
Dinos Iordanou - Chairman, President and CEO
Yes.
Vinay Misquith - Analyst
And is frequency really at all-time lows now versus the past?
Dinos Iordanou - Chairman, President and CEO
I'm sorry; I didn't get the question.
Vinay Misquith - Analyst
Are frequency levels at all-time lows now versus the past?
Dinos Iordanou - Chairman, President and CEO
Yes. Well, it depends how far back you go. But for the past, I would say, five to 10 years, yes; the trends have been very favorable now for four or five years in a row.

Josh Shanker, Deutsche Bank.
Josh Shanker - Analyst
I wanted to ask this question -- what's happening in the national accounts business? You grew it well last year, and it seemed like this quarter there was a significant pullback in premium volume. Is it more competition there? What's happening exactly?
Dinos Iordanou - Chairman, President and CEO
Well, it's not pullback. We lost a couple major accounts. The national accounts business is -- it's a lumpy business. You are writing -- it's the big accounts that come with big remains. A lot of it is retrospectively rated and high service intensive kind of business. But we had one major account that, through a merger, we lost the opportunity to participate. And you are going to get that lumpiness on a quarter-to-quarter basis because when you're hunting for elephants, sometimes you shoot them and sometimes you don't.
Josh Shanker - Analyst
I was thinking maybe you can clarify -- I thought it was kind of sticky business because nobody wants their employees to have to change the servicing.
Dinos Iordanou - Chairman, President and CEO
Absolutely, it's very sticky business. But when you have a merger of two large companies and they are going to merge the program and you happen to be two different carriers, the acquiring company didn't want to change. And unfortunately, the client we had was being acquired. So, in essence, we lost opportunity. In some cases, you are going to lose some of these accounts also on the basis that -- underwriting. They might want to extract terms that you might not be willing to do, so you have to have the willingness to walk away from business if you believe that the profitability is not consistent with your long-term targets.
Josh Shanker - Analyst
That's a very good answer. And do you have an opinion as to the degree to which -- some competitors of yours are saying that pricing is perhaps showing some signs of improvement. Obviously, you don't agree with that. To what extent do you think -- where are we in the cycle, and how long before there is some sort of pricing turn?
Dinos Iordanou - Chairman, President and CEO
Well, I didn't say I disagree with them. It depends where they are. Overall I think, and as you've seen it, we believe it's still -- the environment is more negative than positive. But on different sectors, especially if you are in the small account business, etc., there is more pricing power for those accounts. We see it with our program business, you've seen it -- but the smaller the account and the more dependent on distribution that it doesn't have a lot of competition, you have more price stability. The larger the account -- that's where most of the mega battles go on with premiums being cut significantly. And we have readjusted our posture and the book of business over the last four or five years because these trends, they are not new trends. These trends, they continue now for about four or five years. We haven't seen an uptick yet that is significant in pricing.
When that happens, it is because there is stress in the system, and the reverse will happen. The small accounts are not going to get the significant increases because probably they are priced reasonably well, and it's the large accounts that are going to get the most significant increases. So the volatility of the business will depend by size of account. And it always happens. In every cycle I went through, large accounts usually, they are more volatile on the way down and on the way up in pricing.
Josh Shanker - Analyst
Thanks for the color.

Matthew Heimermann, JP Morgan.
Matthew Heimermann - Analyst
A couple questions -- first, I was wondering if you could discuss the -- any -- with respect to the -- sorry, I'm mumbling this morning -- executive assurance, the premium declines there -- was any of the decline related to accounts maybe reverting back -- that you picked up during the financial crisis -- that reverted back to pre-crisis carriers? Or was all of that driven by just pricing indication?
Dinos Iordanou - Chairman, President and CEO
Well, I will attribute most of it on account selection and pricing, especially on the financial institutions and commercial D&O space, and within we have a terrific team underwriting and we allow them to make those judgments. There has been pressure on pricing, and we don't believe that's justifiable. Some of our competitors think it is still a very good business, so we have walked away from accounts.
Matthew Heimermann - Analyst
And then, with respect to the PML or the excess capital, I guess, as I think about -- I kind of -- at this point, it seems like with the mix shift, PML is probably the biggest or disproportionate driver of your excess capital. One, do you think that's correct? And two, I would presume that you probably, in this type of environment, don't want to go right up against the 25% threshold, given that if something did happen you probably wanted to have room the next day to write business. Is that -- my other question would be, is that a correct assessment as well?
Dinos Iordanou - Chairman, President and CEO
In general, yes. We always want to maintain our capital requirements on the 8-plus level by the rating agencies, plus a cushion above it that the combination of expected earnings for a year plus the cushion will give us enough room that if we have the one in 250 event, we begin the year and we end the year with A-plus capital adequacy based on the rating agencies' models. So in essence, your question is correct. I want to be standing. Even if I get a little wounded, it might be a small flesh wound and be able to capitalize the day after, after a major event. And that's the way we have been running the company for the last nine years, and as long as this management team is around it will continue to be in that fashion.
John Hele - EVP, CFO and Treasurer
Maybe just -- I want to clarify that so you understand that, when we talk about our excess capital, this is the amount above our target rating for capital, which is A-plus, plus the buffer that Dinos spoke about. So the numbers we give you are above that -- our targeted level is the rating plus a buffer. And the buffer is there in order -- if there is a big cat event, that plus the earnings in the year, we have lots of capital left to write the business.
Matthew Heimermann - Analyst
Yes, I guess I'm just trying to translate that into an easier metric for us on the outside to look at, and that's why I was wondering if we should just -- whether it was reasonable to think about, in the current environment, given cat prices have come down, that there probably -- you know, 25 -- you probably -- is that fair, then, that 25 is probably too aggressive to kind of --?
Dinos Iordanou - Chairman, President and CEO
I don't view 25 as too aggressive. But you're also right; if pricing was better, you'll see us more on the -- as the new terminology, being overweight than underweight . So we are a little bit underweight right now, and probably it is because of
John Hele - EVP, CFO and Treasurer
Which would impact our excess capital. We would tend to use some of that more for going to 25%, if that was good returns, versus other things.
Matthew Heimermann - Analyst
Okay, realized I'm kind of splitting hairs here. The other question, just, John, to follow up on your yields curve positioning comment relative to potential changes in the bond market related to quantitative easing, and I think you were talking more about the consequences out over the next 12 months than what the bond market has already done, I think, in response to potential easing. But could you just give us a sense of tactically how you think you are positioned today relative to any increase in -- or I guess what's your base case for how the yield curve may change over the next 12 months, and if you reposition, where would you likely expect those changes to come across durations?
John Hele - EVP, CFO and Treasurer
Well, we increased the duration this year, these past few quarters, primarily through buying slightly longer treasuries. And we did that so that -- they are liquid, they are easy to sell out of if you need to, quickly, or you can always add a derivative on top if we want to move quite quickly and then go shorter. And the reason is, it's very hard to predict what the impact of this is going to be. If QE2 works well, like I think the Fed hopes it does, then rates are going to go up. But it may not. We're in uncharted territory here, so we are trying to be well-positioned no matter which option happens.
Matthew Heimermann - Analyst
I guess maybe a different way to ask that question -- today, are you disproportionately exposed to a parallel shift relative to -- in the curve relative to flattening, or vice versa?
John Hele - EVP, CFO and Treasurer
No, I wouldn't say disproportionately. I guess it depends on your baseline. We are spread out evenly. The whole duration is 3.11, and it's spread out over the next period of time to get you that sort of duration. But it's not super-barbelled or anything, if that's what you're thinking about.
Matthew Heimermann - Analyst
Yes, that's what I was asking. All right, much appreciated. Thanks, guys.
Operator
Brian Meredith, UBS.
Brian Meredith - Analyst
Two questions, first one on -- back on the excess capital. I'm just wondering -- your appetite potentially to take on some additional debt here, given the incredibly low rate environment and potentially using that for excess capital, buying back stock?
Dinos Iordanou - Chairman, President and CEO
We don't aspire to that philosophy. In the way we construct the balance sheet, we always want to have room for debt and hybrid, in case of the unusual event, because we believe that if the market turns on a dime because of something big and we have competitors that they are in difficulty from a capital point of view, we will be able to take advantage of that opportunity without having the necessity to go and reissue common stock. So also, depending where the cycle is, we have much more of a willingness to have more financial leverage on the balance sheet. In a good cycle, I don't mind financial leverage going up to 30% or thereabouts, where in the soft cycle I'd rather have less financial leverage than most because it gives me that flexibility. At the end of the day, you have to be preparing for the day after, after a major event. And not only our philosophy about keeping excess capital, but also how the capital structure is constructed is very important to us. So for the time being, we want to continue to have low financial leverage on the balance sheet.
John Hele - EVP, CFO and Treasurer
And even though nominal interest rates are at relatively low rates, the spread over treasuries is not at an all-time low. It's getting better, slowly and throughout the year, but not something you'd say I've got to rush out and do this, this is the deal of a lifetime. And we work off the spreads when Arch issues debt. We immunize it with matching treasuries on either side, so the net cost to the shareholder is only the spread.
Brian Meredith - Analyst
Okay, so you focus the spreads. Great. And then the second one -- on the 9% to 10%, ROE, Dinos, I guess a couple questions there. One, what are you assuming with respect to investment yields? Are you assuming whatever the yield is in your current portfolio? Is that new money yields? Then also, what do you assume with respect to trend in that number?
Dinos Iordanou - Chairman, President and CEO
We're assuming new money invested [yield].
Brian Meredith - Analyst
Okay, so which is (multiple speakers) below which -- where you are right now?
Dinos Iordanou - Chairman, President and CEO
I'm sorry?
Brian Meredith - Analyst
Which is probably below where your current portfolio yields are right now; right?
Dinos Iordanou - Chairman, President and CEO
Yes, but not significantly below, because in the Company when I talk to our Chief Investment Officer, etc., he is able to maintain -- don't forget our portfolio turns significantly every year. We've got $3.5 billion to $4 billion turning over between new cash flow and things maturing. And he is finding opportunities to maintain close to our embedded yield. So we view that as the normalized capital that you are going to use to write that business, not all our total including the excess capital because that would be fooling you on the calculation. And also, what is the normalized yields on new money invested? That's the calculation we go through when we give you those numbers. That's why, in my prepared remarks, I said normalized.
Brian Meredith - Analyst
Okay, excellent, thank you.

A couple questions -- first, building on the answer to the last question, your preferreds come up for redemption early part of next year. So, to the extent that you decide to redeem those, would you be just diverting then, funds from common stock buybacks in order to do that, or would you be more looking in terms of a refinance there?
Dinos Iordanou - Chairman, President and CEO
If we redeem them it's because we have the ability to replace them with the same kind of securities at a lower cost. So if that happens, the option to call them is ours. We can exercise only that option if I can improve the economics. But I'm not changing the capital structure.
Mark Dwelle - Analyst
Okay, that's helpful. And second question is, you commented in the report about exiting the aviation market, and there was a fairly sizable reduction, then, in the amount of business written in the marine, aviation -- the energy line. Was all of that reduction simply the aviation going away, or was a portion of that declines in those other items that are in (multiple speakers)?
Dinos Iordanou - Chairman, President and CEO
No, it was primarily the commercial aviation and some space business. And our decision to exit it was more as to what we think the prospects of that business is over a 30-year period of time. We didn't think that, when you put the good years, the bad years and you mix it all together, the return over a long period of time is not good enough for us.
Mark Dwelle - Analyst
Okay, that was actually going to be my follow-up question. I'll stop there, thank you.

Jay Cohen, Banc of America/Merrill Lynch.
Jay Cohen - Analyst
Three questions -- last quarter you had mentioned that some of your casualty reserves in the most recent accident years had shown some deficiencies, and I'm wondering if you can update us on that. Did you see a similar thing this quarter?
Dinos Iordanou - Chairman, President and CEO
No; there was no change in our casualty risk for this quarter. And basically what we said last quarter was that -- we had something specific to a big account we wrote back in the '03-'04 year, and then it was a little bit on the executive assurance, E&O area, because of Madoff-related. That's the only thing we talked last quarter, and none of that had any effect on this current quarter.
Jay Cohen - Analyst
That's great. Second question -- another management team in a conference call earlier today suggested that they were seeing less of a trend of standard insurance companies taking business from the E&S market, so that trend was declining. Are you seeing any signs of that happening, given that you are a big E&S player?
Dinos Iordanou - Chairman, President and CEO
Well, it is off of it. But let me tell you, in the last three years it was a massacre. They haven't seen anything on E&S that they didn't like to write it on an admitted basis. But that movement has happened already. So the E&S market will shrink and expand based on the cycles, and right now it has shrunk enough, in my view, maybe more than it should have. But if direction -- I wasn't on the call; I don't know whom you are referring to. But if it is a directional issue, I think it is accurate that it is less now than it was maybe six months, a year ago. But it's still happening. It's not zero, but directionally there is a little less of that.
Jay Cohen - Analyst
And then the last question, broker remuneration -- what's happening there as far as overall commissions?
Dinos Iordanou - Chairman, President and CEO
Well, there is pressure for increased commissions, and at the end of the day you negotiate on account by account, and you've got to factor that in, in your pricing. But if you look at our numbers, probably year-over-year -- and you've got to adjust for mix, which is what -- you don't have all the clarity that we have -- we are probably paying close to another point or so in commission, if you take it product by product. So they effect -- and that effect, it wasn't just overnight. It happened over the last couple of years. When premium rates -- no, let me rephrase that.
When premium volume for the whole industry is coming down, and this is the fourth year in a row we are going to have less premium written, there is more pressure for the brokers and agents to be asking for a little more on commission, and eventually finds its way into our financials. So there is pressure there.
John Hele - EVP, CFO and Treasurer
But in our published ratios, if you look at the long-term trend, it is what Dinos just mentioned, plus this mix is -- it's quite a big impact, because we are shifting to much smaller business, SME type businesses, mid-size accounts, and that really has quite an impact.
Jay Cohen - Analyst
Right, great, thanks for clarifying that.

Keith Walsh - Analyst
Most of my questions have been asked and answered, but just one -- if you could comment on what you are seeing out there in the competitive market regarding terms and conditions on policies? I'm getting a lot of -- I'm hearing a lot of deterioration going on there.
Dinos Iordanou - Chairman, President and CEO
The terms and conditions were not an issue in the last three, four years prior to the last year. It's in the last year, 18 months that -- so the softening of rates, it was mostly pricing, prices that were coming down, but terms and conditions that were pretty stable. We've seen that, beginning -- well, it's not today; it's been for about 18 months or so, we've seen the beginning of the erosion of terms. But it's not in the same fashion of craziness we've seen in '98 or '99 or 2000. And what the future will bring is anybody's guess, but there is more pressure, more requests by clients, the brokers, for broadening terms. And in some cases, some companies acquiesce to them.
Keith Walsh - Analyst
Thanks a lot.
Operator
Ian Gutterman, Adage Capital.
Ian Gutterman - Analyst
First quick one -- can you remind me, on the fac side, what limits you write to?
Dinos Iordanou - Chairman, President and CEO
Which side?
Ian Gutterman - Analyst
On the facultative business, how big a limit you offer?
Dinos Iordanou - Chairman, President and CEO
On the property fac?
Ian Gutterman - Analyst
Yes.
Dinos Iordanou - Chairman, President and CEO
Net or gross?
Ian Gutterman - Analyst
I guess net.
Dinos Iordanou - Chairman, President and CEO
Our net is $25 million, our gross line is $100 million.
Ian Gutterman - Analyst
Okay, and then what's sort of a -- obviously, that's been a very favorable line as far as experience this year. What sort of a normal, if you will, a normal once-a-year type of back quarter? Is that several $25 million losses? Assuming it's not from a cat (multiple speakers) --?
Dinos Iordanou - Chairman, President and CEO
Our average limit on that business is a little less than $12 million. So we don't write a lot of accounts without the big net. So we haven't yet had a $25 million loss, and so -- it's lumpy business, but we have been at it now for over three-plus years, and we have done very well. I think we have one of the best teams and they are very good underwriters, and we are happy with the product line and what they do for us in the marketplace.
Ian Gutterman - Analyst
Okay, and (inaudible) agreed, it's a very good business; I'm just trying to get some sense of the sensitivity, if we do have a bad quarter (multiple speakers).
Dinos Iordanou - Chairman, President and CEO
It could be lumpy, as we said. This quarter accident year was better because we didn't have any large, what we would call traditional losses.
Ian Gutterman - Analyst
Okay, great. And then if I can take another stab at the excess capital, John, if I just do some math here, the 18% PMO you discussed is obviously $800 million of P&L, over $4.4 billion of equity. If I take that to your 25% limit, that's $3.2 billion of equity, right, $800 million over $3.2 billion, which implies a $1.2 billion difference. So that implies, if I take away the $900 million to $1.1 billion of excess, that your cushion you're talking about is only $100 million to $300 million. Is that right?
John Hele - EVP, CFO and Treasurer
No. Did you put the expected earnings over a year?
Ian Gutterman - Analyst
Well, I'm saying, but if we had a big cat event tomorrow, if --
John Hele - EVP, CFO and Treasurer
But the (multiple speakers) [correlation] is you take --
Ian Gutterman - Analyst
Why do we have to assume that the earnings come in, in a year?
John Hele - EVP, CFO and Treasurer
Because the goal is, we want to have it over a 12-month period, we would recover enough to have the business. So we get the count, the expected earnings that will flow out from our book of business.
Dinos Iordanou - Chairman, President and CEO
And the other area you have to go, Ian, is that, from a rating point of view, is your total capital, not just common equity capital.
Ian Gutterman - Analyst
I see.
Dinos Iordanou - Chairman, President and CEO
Well, but you left some $625 million out of that equation, because we have $300 million long-term debt and we have $325 million of perpetual preferreds, so that counts as capital. So you can't ignore that as part of the calculation, as to what is your rating agency capital requirement and how do you go about it.
Ian Gutterman - Analyst
But when you're talking about an excess, I thought you'd give the PML target as a percent of equity. So when you're talking as excess, is that including debt capacity, or is that just equity?
Dinos Iordanou - Chairman, President and CEO
No, no, it's total capital. Right?
Ian Gutterman - Analyst
But I mean the excess number, the $900 million to $1.1 billion. Is that including your unused debt capacity, or is that $900 million to $1.1 billion (multiple speakers) of excess equity, plus you have excess debt capacity on top of that?
Dinos Iordanou - Chairman, President and CEO
No, let's start from the beginning. At the end of the day, rating agencies, they look at your total capital you are operating with. The common, preferred and debt, 30-year debt, that you get credit for.
John Hele - EVP, CFO and Treasurer
What you have today.
Dinos Iordanou - Chairman, President and CEO
What you have today. Okay? So in essence, that's the part that we allocate to the operating units, and that's the part that we've got to give them some cushion to operate above it. The fact that we chose 25% of common equity as a target, it's immaterial to that calculation, just --
John Hele - EVP, CFO and Treasurer
That's a risk measure.
Dinos Iordanou - Chairman, President and CEO
That's a risk measure. It's a risk tolerance measure, and I don't count my long-term debt in my perpetual as my own capital, so in essence I don't want to take risk on that. I'm only taking risk on the common equity.
John Hele - EVP, CFO and Treasurer
[Work down] to the PML.
Dinos Iordanou - Chairman, President and CEO
Right. So if you do your calculations now in the same fashion you've done them with common, you get to the same place as we are.
Ian Gutterman - Analyst
No, that's right, I understand that part. I guess what I am concerned about is, if I took $1 billion of your equity, right, I assume if you did a $1 billion buyback tomorrow, just for argument's sake, you go from $800 million divided by $3.4 billion, you would be at a 23% PML. And then if you had an $800 million event the next day, and the $3.4 billion goes down to $2.6 billion, which would be 30% of equity. I just -- knowing the way the rating agencies work, although you and I would argue that you should have a year to earn back and get back to your 25%, realistically the agencies will say (multiple speakers) --
Dinos Iordanou - Chairman, President and CEO
No, but even if that happens, don't forget you've got to add up the other capital that I get credit for. Right?
Ian Gutterman - Analyst
Sure.
Dinos Iordanou - Chairman, President and CEO
So this is a company who writes $2.5 billion of premium, and if you do the calculations correctly, you will know that I will still have A plus adequate capital.
John Hele - EVP, CFO and Treasurer
Plus, Ian, this target is our target, Arch's target as a percentage of common equity that we set as a risk measurement system. It wasn't dictated by the rating agencies to us. And rating agencies will, in major events -- they do give you some time to recover because not everybody calls. We have the time to repair our balance sheet, and they take that into account in all their ratings when they look at it.
Ian Gutterman - Analyst
I guess I'm trying to do this math on the fly here, but your 25% equity limit is about a 21% of capital limit. I guess, is your -- so is your rating consistent with the 21% limit, or are you able to go up to a 25% of capital and still maintain your rating?
Dinos Iordanou - Chairman, President and CEO
We can go to 25% of capital and still maintain our rating.
Ian Gutterman - Analyst
Okay, that was the part that I was unclear.
Dinos Iordanou - Chairman, President and CEO
Yes.
Ian Gutterman - Analyst
Okay, thank you.
Operator
Gregory Locraft, Morgan Stanley.
Gregory Locraft - Analyst
I wanted to get a sense on -- from a bigger-picture perspective, the mix of business between reinsurance and insurance, and bear with me. As you guys really shrink the reinsurance business based on your commentary, the total overall book seems to be more and more skewed towards insurance, not because you're growing insurance, but because it's shrinking less. My question is that, that segment has not generated nearly the profitability for the last couple of years that the reinsurance segment has. So, how should we be thinking of that mix shift, or do you even think of it at your level going forward over the next several quarters and years?
Dinos Iordanou - Chairman, President and CEO
Well, we think about it, but we don't have any targets for it because at the end of the day you've got to allow the business to run independent and see what is available in the market and what they are writing. All I can tell you is that the major adjustments in reinsurance have taken place already, because most -- unless the property and property cat business -- which is a possibility -- goes extremely negative and is unprofitable, then you will see further actions (technical difficulty) that I think you're probably getting more closer to a steady, steady kind of run rate there.
Having said that, insurance had significant shift. Even though volume wise it might not be noticeable to you, when you look at the portfolio from the inside out, you will see that we are writing a lot more small- to medium-sized accounts than ever before, and we are in lines of business that were insignificant a few years ago and they are more significant today, that give us pretty good profitability. Collateral protection, for example, is -- it's an area that we've been in it since the beginning. This is a company we have in Kansas City, it writes predominantly a gap program. For those of you who don't understand what the gap program is, it's -- you buy an automobile and you buy your insurance. But let's say it's on a lease, and then you have an accident or the automobile is stolen and then your primary insurance under the comprehensive will give you the bluebook amount, and that might not be good enough for the balance you have on the lease; the gap program covers that differential. That business has been a small part of what we did. We went through the financial crisis, it performed extremely well. And now, there is more opportunities to grow it and we have chosen to grow it in the last year, year and a half, with excellent results.
So there is confirmation in our book of business that it might not be totally visible to you. And it happens based on what we believe the ability of us is to get an adequate return. Now, having said that, probably because of several lines of business which -- they are more volatile; property, property cat, there is more volatility on those. You have higher return expectations. And since we do more of that on the reinsurance side, over the long term I can tell you our reinsurance operations will have better ROEs than the insurance operations.
Having said that, there will be more volatility on top line for the reinsurance group. They will grow exponentially in the good times, and they will probably shrink significantly in the soft, to maintain that ability for us to have the higher ROE performance.
Gregory Locraft - Analyst
And you had mentioned just now in the thoughtful answer that the ROE in reinsurance is higher than insurance. I guess that's across the cycle. Why is that? What structurally is the reason?
Dinos Iordanou - Chairman, President and CEO
Well, structurally the reason is because there is more volatility in that business, and for that reason your return expectations have to be higher. The more -- if you give me a contrast that to a low frequency, low severity type of business, I will probably accept a 10%-12% ROE because it comes steady with very low volatility over a long period of time. But I will not write --
John Hele - EVP, CFO and Treasurer
Property cat.
Dinos Iordanou - Chairman, President and CEO
-- Property cat over a long period of time with the same ROE expectations. My ROE expectations have to be in the 20s for that type of business.
Gregory Locraft - Analyst
Okay, so, embedded in your pricing models, then, there's a lower ROE expectation in insurance, given the more predictable income stream from that segment?
Dinos Iordanou - Chairman, President and CEO
In general, that is correct. But you've got to go line by line and product by product.
Gregory Locraft - Analyst
And then just a miscellaneous question -- how do you guys think about the mortgage put-back in foreclosure issue? Anything we should be concerned about in your particular book, or no?
Dinos Iordanou - Chairman, President and CEO
Not from a liability point of view. It's a nonevent for us in our book of business. Having said that, maybe we might get a little uptick on the investment side because, in essence, when PIMCO and BlackRock, etc., they are doing this on behalf of clients. And I'm sure somewhere on our mortgage-backed security portfolio we may have an issue where we might get a little benefit. But it's insignificant area. It's nothing that we worry about.
John Hele - EVP, CFO and Treasurer
And so far, in the MBS/CMBS world, the pricing hasn't really fundamentally changed with all this noise in the papers so far. We'll have to wait and see how it all develops.
Gregory Locraft - Analyst
Last, just your thoughts on Solvency II -- does it have any impact to you, and what do you think it does to the marketplace?
Dinos Iordanou - Chairman, President and CEO
Well, they haven't finalized it all. Two things that are clear is that capital requirements will go up, more on the life sector than on the P&C sector. And when capital requirements go up, if you are a reinsurer, which is another form of capital for potential clients, it might give us some opportunities to deploy some capital when that happens, especially in Europe. For companies that they might not want to access the capital markets and they might want to do it through reinsurance.
So for us, Solvency II, other than the administrative bureaucratic processes that it might add a little cost is more of a positive from a capital point of view because we are a company, through our reinsurance operations, that is willing to be a capital provider to clients if they need it through reinsurance content.
John Hele - EVP, CFO and Treasurer
I think it's still early to understand the amount of the impact. All firms, European firms, including our European subs, are working on the Quantitative Impact Study number 5 that's due at the end of October, and that will be assimilated and gone through. And the next year, they will probably recalibrate the models once again. And then everyone will have a better idea as to what it will be. But I think the general consensus is, it's going to result in higher capital, and it will be interesting for how European mutuals and others look at this. So we think there could be an opportunity here for reinsurance solutions to help with that.
Gregory Locraft - Analyst
Okay, great, thanks for the answers.
