Good day and welcome to the Unum Group first-quarter 2011 earnings results conference call. This call is being recorded. At this time for opening remarks and introductions, I would like to turn the call over to the Senior Vice President, Investor Relations, Mr. Tom White. Please go ahead, sir.
Tom White - SVP of IR
Great. Thank you, operator, and good morning, everyone. Welcome to the first-quarter 2011 analyst and investor call for Unum Group.
Our remarks this morning will include forward-looking statements, which are statements that are not of current or historical fact. As a result, actual results might differ materially from the results suggested by these forward-looking statements. Information concerning factors that could cause results to differ appears in our filings with the SEC. They are also located in the sections titled cautionary statement regarding forward-looking statements and risk factors in our annual report on Form 10-K for the fiscal year ended December 31, 2010. Our SEC filings can be found in the investor section of our website at www.Unum.com.
I'll also remind you that the statements in today's call speak only as of the date they are made and we undertake no obligation to publicly update or revise any forward-looking statement.
A presentation of the most directly comparable GAAP measures and reconciliations of any non-GAAP financial measures included in today's presentation can be found on our website also in the investor section.
Participating in this morning's conference call are Tom Watjen, President and CEO, and Rick McKenney, Executive Vice President and CFO, and also our business segment Presidents, Kevin McCarthy, Randy Horn, and Jack McGarry.
Now I will turn the call over to Tom Watjen. Tom?
Tom Watjen - President and CEO
Thank you, Tom, and good morning. Our first-quarter results are a good, solid start to 2011 and are in line with our expectations. We continue to see generally stable risk experience particularly in Unum US but also in Unum UK and Colonial Life, where we've seen some volatility in past quarters. Rick and Tom will talk in greater depth about our results for the quarter.
But before they do, let me just touch on a few highlights that I think are noteworthy. First, we continue to report modest earnings per share growth in part driven by our improvements in -- continued improvement in Unum US earnings as well as we are also continuing to benefit from our share repurchase programs.
Second, we continue to maintain a very strong capital position driven by our solid operating results and strong investment performance. Our weighted-average risk-based capital ratio ended the first quarter at approximately 395% and our holding Company's cash and marketable securities position is over $800 million.
Third, we are growing in most of our target markets. Unum US operations showed a 10% growth in new sales this quarter with a 10% growth in Voluntary Benefits, 7% growth in Group LTD, and 8% in Group Life.
At Colonial, we continue to see modest growth in our core commercial markets, which remains a sweet spot for Colonial with pressure certainly continuing to come from our sales in the public sector and the large case marketplace which we expect to continue to be choppy.
As we expected given the pricing actions we're taking in the UK market, sales were down in Unum UK but we continue to have a very positive outlook about that marketplace. I might add that we have not seen any material change in the economic or competitive environment. We fully expect the environment obviously to improve at some point, but until it does, we remain committed to maintaining a disciplined strategy that has served us so well over the last several years.
Fourth, our investment portfolio remains in excellent shape with strong credit quality and generally stable portfolio yield. As you know, our current Chief Investment Officer, David Fussell, has been trying to retire for some time and we are pleased that his replacement, Breege Farrell, has joined the Company as our Chief Investment Officer. We look forward to the contributions that Breege will be making with our already strong investment team.
Next, as I mentioned earlier, we continue to aggressively repurchase stock with a total of $224 million repurchased this quarter and $580 million repurchased over the past 12 months or about 12% -- excuse me -- about 8% of our outstanding shares. Our capital strength and flexibility remains a significant asset.
The last point I wanted to make before turning things over to Tom is that the consistency we are experiencing in our results today is no accident but the results of a several year process to reinvent the Company. Our strategy is grounded on maintaining a disciplined approach to the market with a focus on profitability, not just topline growth.
As a result of our more disciplined targeted efforts, we have shifted our business mix to a better balance of core markets versus large case business and a better spread of business including a greater portion of our business coming from non-disability lines.
We have therefore not experienced the volatility that some others have had and we remain committed to following this more disciplined, measured approach to the business.
Now I will ask Tom White to provide an overview of our operating results. Tom?
Tom White - SVP of IR
Great. Thanks, Tom. Net income for the first quarter was $225.4 million or $0.72 per diluted common share, compared to net income of $229.8 million or $0.69 per diluted common share last year. Included in the results for the first quarter of 2011 are net realized after-tax investment gains of $9.7 million or $0.03 per diluted common share compared to net realized after-tax investment gains of $16.5 million or $0.05 per diluted common share in the first quarter of 2010.
Also included in the results for the first quarter 2010 is a tax charge of $10.2 million or $0.03 per diluted common share related to the change in tax treatment of the Medicare subsidy for retiree health benefit plans.
Net realized after-tax investment gains for the first quarter of 2011 include an after-tax gain of $9.1 million resulting from changes in the fair value of an embedded derivative in a modified coinsurance contract compared to an after-tax gain of $11.9 million in the first quarter of 2010. Also included in net realized after-tax investment gains for the first quarter this year are net realized after-tax investment gains of $600,000 related to sales and write-downs of investments compared to net after-tax gains of $4.6 million in the year ago quarter.
So excluding these items, after-tax operating income was $215.7 million or $0.69 per diluted common share, compared to $223.5 million or $0.67 per diluted common share in the year-ago quarter.
Turning to the operating segments, in total Unum US operating income increased 5% to $209.1 million in the first quarter. Within Unum US, the Group Disability line reported another solid quarter from a risk perspective, though operating income declined 3% to $73.5 million as net investment income declined primarily due to a decrease in the level of assets supporting this line of business.
Within the Group Life and AD&D line, operating income increased 3.1% to $52.8 million in the first quarter with higher revenues offsetting a slight uptick in the benefit ratio. In the supplemental and voluntary line, first-quarter income increased 14.7% to $82.8 million. The year-over-year improvement was driven primarily by a strong rebound in earnings from the Voluntary Benefits business line, which more than offset small declines in income from the recently issued individual disability line and the long-term care line.
Moving to Unum UK, operating income in this segment decreased 19.6% to $48.7 million in the first quarter of 2011. Operating income declined 21.9% in local currency. While premium income in local currency was down 1.8% in the first quarter, the benefit ratio was higher at 69.3% compared to 63.1%, reflecting the impact of higher inflation on claim reserves associated with policies containing an inflation-linked benefit increase feature, a lower level of claim resolutions in Group LTD, and lower premium income. These items offset favorable Group LTD claim incidence relative to the year-ago quarter.
Concluding our core operations, Colonial Life experienced a 5.5% decline in operating income compared to last year as premium income growth of 5.8% was offset by a higher benefit ratio. The Individual Disability Closed Block operating income was $9.9 million first quarter 2011 compared to $11.7 million in the year-ago quarter.
The interest-adjusted loss ratio was slightly higher at 84.7% this quarter compared to 84.5% in the year-ago quarter. This was driven primarily by lower premium income, which declined 5.5% due to the expected runoff of the Closed Block. Net investment income declined 4.6% due to a lower level of bond call premiums and a decrease in the level of assets.
And finally, the Corporate and Other segment reported an operating loss of $21.7 million compared to a loss of $8.9 million in the year-ago quarter.
Interest expense increased to $34.9 million this quarter compared to $30.3 million in the year-ago quarter, reflecting the debt issuance from September of 2010. During the first quarter, we paid off at maturity $225 million of our 7.65% senior notes which were due March of 2011. This will result in a lower interest expense going forward.
In addition, net investment income in the Corporate and Other segment was lower, driven primarily by lower income from private equity partnerships and our investments in low income housing tax credit partnerships. Our increased activity in tax credit partnerships over the past year contributed to a lower income tax rate in the first quarter compared to a year ago.
So with that overview of the operating results, I will turn the call over to Rick McKenney, for a further analysis of this quarter's results.
Rick McKenney - EVP and CFO
Great. Thank you, Tom. A few topics on the quarter, which continues with the theme of stability. The areas I am going to cover are the key profitability drivers for our business lines. This is a snapshot of our investment portfolio and an update on our capital position and actions.
Starting with the risk experience for our primary business lines, in Unum US, risk experience remained generally stable again this quarter. Our Group Disability performance remains favorable with the benefit ratio declining slightly this quarter to just under 84%, which is down from the 84.2% we saw in the first quarter of last year and down sequentially from the fourth quarter. New claim incidence continued to show some volatility but was down slightly on a sequential basis relative to the fourth quarter and it remains within a range of experience we have seen over the past several quarters.
Claim recovery experience remained favorable in the first quarter. We have no reason to believe this will change and we will look for similarly consistent levels in the Group Disability benefit ratio in the future and longer-term improvement in profitability will be driven from business mix shift to more core market and Voluntary Benefits.
For the Group Life and AD&D line, results were generally stable with a slight uptick in mortality experience producing a benefit ratio of 70% which is consistent with the year-ago quarter.
Looking to the supplementary and voluntary lines, voluntary benefit earnings were strongly up this quarter with favorable risk experience especially in the Disability and Life lines of business. Premium income in this line was also quite strong, growing 11.2% year-over-year. The loss ratio in the recently issued Individual Disability Line was slightly higher than the level of last year but risk experience remained relatively stable.
Finally, long-term-care loss ratios were up year-over-year but consistent with the fourth quarter. We continue to make good progress on the individual long-term care rate increases that we began to file in the fourth quarter of last year and we filed in 46 states and the District of Columbia. So far we have almost received 90% approval out of the 26 states that have reached a decision and we continue to work with the remaining states. The additional premiums in this rate increase will emerge over 2012 and 2013.
Moving to our Unum UK results, we are pleased with the stability and the financial performance for this segment in the first quarter compared to the fourth quarter of 2010, though comparisons to the year-ago quarter show earnings that were substantially lower, as we have been discussing for several quarters.
The benefit ratio for the first quarter was 69.3%, down from 71.7% in the fourth quarter with favorable Group long-term disability claim incidence offsetting some higher Group Life mortality experience.
And finally on Colonial Life, earnings and risk results for the first quarter were within our expected range particularly for the accident, sickness and disability line of business that produced adverse claims trends in the fourth quarter of 2010.
The benefit ratio of 51.4% this quarter included less favorable risk results in the accident, sickness, and disability line due to a higher level of incurred claims as well as slightly unfavorable mortality experience in the lifeline of business but remained within our expected range of 50% to 52% for the segment.
Looking at the premium line, first with Unum US, new sales in the segment showed some positive momentum for us in the first quarter, growing 10% in total with much of this growth coming from sales of new business to existing customers.
On a product line basis, sales of Group long-term disability increased 7% and Group Life increased 8%. Within these Group lines, our new case count sales were up 14% relative to last year with particular strength in the smaller case size portion in the market. We continue to see strong new sales growth in the Voluntary Benefits marketplace with premium sales this quarter increasing 10% and new case count growth of 21%.
At Unum UK, we continue to work to increase price in the UK Group risk market and are pleased that persistency, while lower than last year, is holding up well relative to our expectations. There is pressure on sales comparisons, which are down 29% compared to the year-ago quarter in local currency. This reflects the current competitive environment in the UK in conjunction with our pricing actions.
In aggregate, we are seeing greater stability in our premium income line which declined 1.8% to GBP104 million in the first quarter. We are pleased with the progress that Jack McGarry and his team are making in implementing several important operational initiatives including these programs related to renewals of existing in-force business.
Finally, sales in the Colonial Life segment were softer this quarter, declining 4% after several consecutive quarters of growth. Breaking it down, though, we continue to see positive momentum in the core commercial market segment, which are cases with less than 1000 lines.
This area saw 2% growth, however, sales were lower this quarter in two areas which can be more lumpy, and that is the large case commercial market and the public sector market.
Our sales to existing accounts showed slight improvement compared to last year, driven by favorable results from new sales into existing cases. And importantly on the recruiting front, our new rep contracts grew by 7% in the quarter.
Turning attention to the balance sheet and the investment portfolio, we continue to see excellent results. The credit profile of our investment portfolio remains strong with the net unrealized gain position in our fixed maturity securities portfolio at $3.3 billion at quarter end and our portfolio watch list showing no signs of deterioration in the first quarter.
You should also note that since the end of 2009 in aggregate we have booked a net gain in our results from the investment portfolio. Although challenging, the low interest rate environment continues to have only marginal impact on the Company. Our portfolio yields continue to hold up well, with our aggregate portfolio yield of 6.69%, down only 6 basis points over the past year. The yields on the various investment portfolios backing our product lines also showed similar stability. The yield net of our discount rate for Unum US Group LTD, the business remains in good shape at 97 basis points at March 31 and our discount rate is unchanged.
With these stable operating results, book value per share continues to grow increasing 10% to $29.08 at March 31, 2011. And looking at our capital, our statutory earnings start out the first quarter of 2011 in line with our expectations. Net income on a statutory basis for our traditional US Life Insurance subsidiaries in the first quarter was $142 million. This is a level consistent with our full-year expectations that we believe will continue to drive strong growth in our capital position.
The weighted average risk-based capital ratio for our traditional US-led companies was approximately 395% at quarter end, toward the upper end of our target range for the year. And holding Company cash and marketable securities totaled $816 million.
During the first quarter, we paid off $225 million of maturing debt and repurchased $224 million of our stock. As Tom mentioned, in the last year we have bought back roughly 8% of our shares and we have remaining share repurchase authorization of $921 million at quarter end. Our leverage ratio finished the quarter at just under 21%.
Finally as we look forward in giving consistent results, we are confirming our previous outlook for 2011, which calls for operating earnings per share growth of 6% to 12%.
Now I will turn it back to Tom for his closing comments.
Tom Watjen - President and CEO
Thanks, Rick. As I said in my opening remarks, I am pleased with our overall results for the quarter, particularly the stable risk experience we saw across the Company. Economic and competitive conditions remain challenging but I believe that our strategy of focusing on consistent profitable growth is the right one for our Company. Our strong capital position and financial flexibility combined with our strong business model has continued to position us well for the future.
This completes our formal comments and, operator, let's move to the question-and-answer session.
Operator
(Operator Instructions). Darin Arita, Deutsche Bank.
Darin Arita - Analyst
I had a question on the UK. (technical difficulty)
Tom White - SVP of IR
Good morning, Darin. I'm sorry, we didn't catch the question. Darin?
Tom Watjen - President and CEO
Operator, why don't we go to the second question? Maybe have Darin get back in the queue. We seemed to have lost him.
Operator
(Operator Instructions). Mark Finkelstein, Macquarie.
Mark Finkelstein - Analyst
Good morning. Maybe I will ask Darin's question. On the UK, sales were obviously challenged in the quarter. Persistency levels came in a little bit. I guess what I'm interested in is I understand we want to be disciplined and profitability has gotten hurt over the last few quarters and we are trying to correct that, which seems like the right answer. But I guess I'm just curious about how do you think about whether we have the right pricing in place, we've overshot a little bit, just give us thoughts on that, please.
Tom Watjen - President and CEO
Yes, Mark, it's a great question and I think as you know, our Company actually went through a very similar exercise with Unum US several years ago, so we have a fair amount of experience thinking about how to go through a repricing exercise and keeping track of the right variables and metrics as we do so.
Maybe, Jack, I'll ask you just to respond specifically to what we are doing in the UK and what you are seeing so far.
Jack McGarry - CEO
Yes, clearly sales are challenged. It continues to be a pretty intense competitive environment. But the fact of the matter is the way that these things are rolling out are very close to what we planned on, particularly around the persistency and renewal. I'd remind you that kind of our historic persistency level has been in the high 80s rather than in the low 90s that we saw last year. We are slightly below that as a result of the renewal actions.
But more importantly than that, we are getting the right actions we are asking for. We are clearly keeping the better performing cases. The cases that we are losing would tend to be unprofitable cases for us and oftentimes in this environment, we are losing them at rates that are below the rates we were charging on in-force.
So we're very encouraged about the margin improvement. We are also encouraged about the fact that the renewal program as it's rolling out is demonstrating our ability to sell value. We don't have to match the lowest rate in the marketplace to keep in-force business. In fact, we have a good margin there.
So we feel like we are pretty much on track. It's very consistent with the experience we saw in the US when we renewed business there, both from a persistency perspective, but also from a kind of margin improvement perspective and the difference between the things we are keeping and the things we're losing.
So right now we're watching it very closely. We are mindful of the impact on in-force premium, but we feel pretty good about where we are.
Mark Finkelstein - Analyst
So persistency is as you expected it to be with the rate increases?
Jack McGarry - CEO
Yes.
Mark Finkelstein - Analyst
Just on the US Group long-term disability, if I look at -- the only data we have is what you put in the back of the supplement regarding reserve roll forwards and this quarter was a really strong quarter for claim recovery patterns. I think it is the highest that you've had at least according to that chart as a ratio to be getting impaired reserves in history basically with one quarter close.
I guess how sustainable is this level of claim recoveries and is essentially the claim recoveries just offsetting the higher incidence that we are seeing from the economy? Can we expect this level of recoveries to continue, I guess is the question?
Tom Watjen - President and CEO
Kevin, can I ask you to take Mark's question?
Kevin McCarthy - President and CEO
Sure. Good morning, Mark. It was an extraordinarily I think good quarter. We have had rock solid recovery patterns now I think for 10, 12 quarters in a row, but this one was particularly strong I think both in terms of recovery counts and also in the average size of the reserves that we were -- on those recoveries. And then to some extent that offset what was incidence levels that were higher relative to last year's first quarter but lower relative to last year's third and fourth quarter and the average size of new submits was a little bit lower than we have been experiencing last year.
So to some extent within all that, you've got some volatility particularly around average sizes of claims. I think in terms of solid recovery performance I expect it to be sustainable. I don't see any reason that that's going to change, but it may not necessarily stay at the high level that we had in the first quarter.
Mark Finkelstein - Analyst
Okay. All right, thank you.
Operator
Darin Arita, Deutsche Bank.
Darin Arita - Analyst
Good morning, maybe we'll try this again. Can you hear me now? Well, Mark did ask my first question on the UK. But I had one on the US. In terms of the voluntary benefit ratio, that has steadily declined over the past few years. I was wondering if you can talk about what's driving this and how much lower it can go?
Tom Watjen - President and CEO
Kevin, do you want to grab that one?
Kevin McCarthy - President and CEO
Yes. Good morning, Darin. I think it's operating sort of about where we expect it to operate -- right in and around 50% or so as a loss ratio. It's been going down primarily because our growth rate in accident and disability and critical illness voluntary lines has been growing faster than the growth rate in our life and the life portfolio is somewhat more mature and therefore has a higher loss ratio. So it has mostly been driven by business mix.
The other I think factor is that we have raised prices slightly in voluntary over the last several years on our portfolio and we continue to manage that business both in terms of participation rates and pricing and size mix, etc. in line with our strategy.
Darin Arita - Analyst
In terms of this business, we are seeing the premium income growth start to accelerate again. Where do we think the growth can go to here?
Rick McKenney - EVP and CFO
On voluntary?
Darin Arita - Analyst
That's right, the supplementary and voluntary business.
Rick McKenney - EVP and CFO
I think in general we expect to outperform the marketplace. In voluntary, we expect right around double-digit growth and sort of on the higher end of double-digit growth, if you will, sort of in the midteens I think is the target level for us in terms of the voluntary business as the economy recovers.
Darin Arita - Analyst
Great. Thank you.
Operator
Colin Devine, Citi.
Colin Devine - Analyst
Good morning, guys. I was wondering if I could touch on three things. First with respect to long-term care, perhaps if you could expand a little bit on the average rate increase you received, what that really means to premium then over I guess if you like the next year? And what even more importantly it's going to mean to that benefit ratio? So the first question there on long-term care.
Second with respect to the UK, maybe I missed it but I've got to say this is the first time that I have heard you acknowledge that you've got a pricing problem on the UK book, unless I misinterpreted what you said. Except I thought I have -- both Jack, Tom, you referred to -- we've been through this in the US. We're doing it again and if you do then have a pricing issue on that block, maybe we can expand a little bit more on what you think the magnitude of that is.
Then finally, I don't want to leave Randy out. On Colonial with the benefit ratio, clearly then the fourth quarter wasn't just an aberration. How long do you see this sort of elevated ratio continuing? And are we going to be at these levels for a while here or can you get it back down?
Tom Watjen - President and CEO
Good. Let me just ask actually Kevin to take your first question on long-term care.
Kevin McCarthy - President and CEO
Good morning, Colin. Let me sort of work my way backwards. I think the result of the rate increases will be largely stabilization in terms of the loss ratio. The average size of the rate increases -- our target ratio level was in and around 25%. On the approvals we received so far, it's south of that primarily driven by the fact that about half of the states have approved the rate increase in the 23%-ish kind of average range and half of them have only approved a partial rate increase in the maybe 10% to 12% range, with the idea that we would have to come back again for a second round.
So I think the premium, as Rick said in his remarks, will emerge more in 2012, 2013, and so sort of in the range of somewhere around $30 million by the time we're finished all the way through the rate increase actions.
Tom Watjen - President and CEO
If I could just tee up to the UK point, actually, Colin, let me just be sure I'm clear. We don't feel we have a problem in pricing, like for example when I referred to the US. Obviously the US had to go through a fairly significant amount of repricing because we had very low returns in that business. But the situation we find in the UK is actually we still have very strong returns. It's just those returns have come down. We want to take the actions necessary to bring them back up again, so it's a very -- maybe the process is somewhat similar, but the starting point and ultimately the ending point in terms of the US versus UK is very, very different.
So Jack is always playfully saying to me that -- don't give me too much grief when I have a 20% plus ROE business and you're talking about pricing actions, because that's really what we're talking about is taking and improving the pricing and returns in a business which frankly already has some very good returns. We just think they can take them to a higher level.
And with that, Jack, maybe just sort of elaborate a little bit on just some of the things that we have been doing. I think you touched on this a little bit earlier, but maybe just pick up on some of my comments.
Jack McGarry - CEO
Yes, we do have a 30% margin in the business. I don't think the problem is with pricing levels as much as perhaps the direction prices were headed in the marketplace and the desire to stop and reverse that direction. Actually you talked about this in fairly good level of detail at the Investor Relations meeting in November about the fact that we had reduced rates in 2009. The market had responded to that very aggressively, still left us with very healthy margins, but had reduced rates across the marketplace pretty dramatically and we were just looking to reverse that.
We feel very comfortable with the level we are rating at now. We feel very comfortable with the profitability of our business. We feel comfortable that the profitability of that business will improve as a result of the rate actions that we are taking. And so we still view this as an extremely high margin, high return attractive market and one that has a huge opportunity for growth as well.
So I wouldn't label it a pricing problem so much as taking some management actions as the market leader to make sure that there isn't a pricing problem in the marketplace in the future.
Colin Devine - Analyst
Okay, Jack, thank you. Just to be clear so we can all relate this to what happened in the US, where you tactically shrunk the size of the book, premiums came down. What should we expect then really in the UK as you go through this? The sort of decline we saw here in the first quarter more or relatively stable, or is it going to --?
Jack McGarry - CEO
I think we would expect fairly stable persistency as we move through the block. Hopefully if the marketplace begins to harden somewhat that things will -- persistency could drift up in the second half of the year. We expect to be completely through pricing actions over the next two years, so we will have been through the entire block from that time and we would expect persistency to improve over that two-year cycle.
Tom Watjen - President and CEO
And Colin, unlike the US, as you know, there wasn't -- Jack, there wasn't a big large cape block for example like we had to tackle in the US, which in effect meant there was big chunks of premium that really had to exit the income statement. That's not the same situation we find in the UK.
Jack McGarry - CEO
No, it's more that -- a lot of the tactics we are using are similar. Some of the results in terms of keeping better business, losing the worst running business, the impact of persistency of the rate actions are similar, but at a very different level and at a very different profitability level than the US.
Tom Watjen - President and CEO
Colin, if we could shift to your last question on Colonial, we have sort of a two-part answer. Maybe just ask Rick to speak a little bit to the benefit ratio and then ask Randy just to speak to just some of the operational trends and mix of business changes that have been going on in the sales activity. But Rick, on the benefit ratio?
Rick McKenney - EVP and CFO
On the benefit ratio, Colin, you would've seen, it has elevated from what were really some very low levels that we saw in 2009, 2008. So I think as we booked about a 49.7 for last year in total, we've gone up to 51.7 in the first quarter and our expectations for the full year will be in the 50% to 52% range, really driven by mix and our expectations of how we price that book.
I would tell you that even with those benefit ratios we're generating very good margins in this book of business at very good ROEs. And I will turn it over to Randy to talk about more on the operational side.
Colin Devine - Analyst
Maybe just one sec then, Rick. When you mention the 52% -- or for Randy -- okay -- is that where you really see it stabilizing? It's not sort of trending back to the 55%, 56% of five or six years ago? Is that what --?
Rick McKenney - EVP and CFO
I would confirm that, yes. We see it stabilizing at those levels. Randy, I'm sorry, go ahead.
Randy Horn - President and CEO
Thanks, Tom, and good morning, Colin. Yes, definitely see stability in that 50% to 52% range. I guess just adding to what Rick said, in first quarter last year, I think Rick gave the full-year number. We had a very low benefit ratio of just north of 47%, so starting out from a low level there. You might recall we did see a pattern of increasing incurrals in the accident, sickness and disability segment over the course of 2010 just absolute higher incurrals for accident and sickness. We did see an increase in incidence of disability claims over the course of 2010 and then we reflected that through some reserve adjustments we took in the fourth quarter of last year.
But at this point, we see things as stabilizing very well. Our disability incidence has actually dropped back down here in the first quarter of 2011. We had a surge in open life claims, Colin, in March, but that really is just expected volatility we get in that line from time to time, don't see any kind of adverse trend or pattern there. In fact, we have seen that open claim level settle back down here so far in the second quarter.
So long story short, yes, we expect things to stabilize in that 50% to 52% range. We've introduced some new products, had some product mix shift that has helped drive it to that level, but we think that will help us on the sales front but still maintain very healthy margins and stable benefit ratios going forward.
Colin Devine - Analyst
Very helpful, thank you.
Operator
Ed Spehar, BoA Merrill Lynch.
Ed Spehar - Analyst
Good morning. I have a question on the UK and I guess when I look at the UK, the difference from the US market for Unum I think is that your market share is about 50% I believe in the UK. So I thought you would have more price leadership than what we seem to be seeing. And I'm wondering is there any concern that this is an indication that the overall return expectation for the Unum UK market is potentially moving more toward the US level? Because as you highlighted, this is a very high ROE business.
Tom Watjen - President and CEO
Let me start but then ask Jack to supplement. I think, Ed, as you know and I think it was alluded to by Jack in one of his earlier comments, we made some pricing decisions a couple of years ago where we had lowered prices; and actually what happened is the market actually not just went to that level but went below it. We didn't really exhibit the kind of market leadership we should actually. And as Jack mentioned, really much of what we're doing right now is acting like a market leader, and early indications are that we can be a market leader and continue to protect prices and protect returns.
But, Jack, again, maybe you could fill in the gaps a little bit on that.
Jack McGarry - CEO
I would agree with that, Tom. We are holding onto the cases, having good persistency. We continue to have not the sales level we were achieving last year but good sales level. Most of our misses in fact in sales were in the Group Life side as opposed to the Group Income Protection side.
So I think we are demonstrating leadership. The worst thing we could do for the market is chase share with price down because we would end up fulfilling that prophecy. So we are going to exert some leadership. We recognize that by us raising rates on our in-force block and having somewhat poorer persistency for a short period of time, that is going to mean sales for some of our competitors. Hopefully they will recognize that and begin to recognize that they can take the opportunity to grow and increase their pricing levels as well.
This is early days. We have been at it for a quarter now really through January renewals. The marketplace hasn't had time to react yet from a pricing perspective, so we are very hopeful that during the second and third quarter they will have that opportunity. We are very optimistic about our ability to maintain -- in fact we are maintaining if not -- in fact, we are improving margins as a result of our pricing actions.
We are improving returns and we also hearken back to the huge opportunity that exists in the UK with only one out of 10 people currently insured for group income protection in a social environment that's really going to be relying more on the private industry to provide protection. So we are very optimistic about the market and our leadership position in it.
Ed Spehar - Analyst
My follow-up would be, I understand you are exhibiting price leadership, but if the market doesn't follow, why wouldn't you go to the market? Is there something about the risk profile of this business that you deem a 20% plus ROE to be necessary? Because I'm assuming that if you thought the risk profile was similar to the US market, why wouldn't you accept the same level of returns if the market doesn't come to where you are, especially considering that you are highlighting a better growth opportunity in the UK relative to the US?
Jack McGarry - CEO
Well, I think a part of it -- because the market hasn't demonstrated that we need to go there. I mean we are a 50% market share leader. We are taking a little hit on persistency right now with the rate actions we are taking, but well within our plan. We are improving margins. To drive the market to the US level of profitability to gain another couple of percent market share doesn't seem like a very good value proposition for us. So as long as we can maintain our market share, we can protect our margins, we can get the returns we are getting, and we can demonstrate that we don't need to be at the market to sell income protection because of our value proposition. We can sell at a premium. We are going to continue to do that.
Ed Spehar - Analyst
I guess I'm not suggesting that you are going to be aggressive to gain 2 points of share. I guess what I'm suggesting if there's some fundamental shift in this market where if you don't follow where everyone else is, your share goes from 50 to 25. Is there some reason for you to require a 20 ROE for this business based on the risk profile of the Unum UK market versus the US market?
Jack McGarry - CEO
Well, first, we see no evidence of that fundamental shift in the market that would -- in fact we see evidence much to the contrary in terms of what we are doing right now. But no, there's no risk profile in this market that requires that level of return. It's the fact that the market -- we are able to achieve that level.
Tom Watjen - President and CEO
If I could add to what Jack just said, again, there really is no evidence there's any difference in the risk characteristics. If you look at the basic fundamental actuarial sort of components underneath this in terms of incidence and claim and duration and those sort of first factors, they are very, very similar to what they are in the US. So there's no fundamental underpinnings in the UK that are all any different than what they are in the US.
I think what we are getting at is as a market leader, we probably made a couple fundamental mistakes a couple years ago, which is why we've made the change in leadership where we were leading with price and we didn't need to lead with price. As Jack mentioned, we have a tremendous value proposition. People truly respect the claim expertise we have in the UK, the service we have in the UK. And so it was a strategy change really, where rather than focus on just leading with price, let's get back to delivering and leading with value, which is frankly we find in the marketplace so far the market is prepared to pay for that value.
Jack McGarry - CEO
In addition to that, we do write at a higher margin than our competitors do.
Tom Watjen - President and CEO
Yes, if customers value that additional value proposition; so I would say we probably erred a couple years ago on choosing to get away from so-called selling value into selling price and that's what we are actually backtracking on that with the actions we've talked about here the last 12 months.
Ed Spehar - Analyst
Okay, thank you very much.

Jimmy Bhullar - Analyst
Hi, thanks. I had a question, one, just maybe if you could talk about competitive trends and just your sales outlook in the US disability market. Obviously this quarter you were up 7% in long-term disability. I think the last couple of quarters you were weak.
And then secondly, on just -- we have heard from -- related to that, we've heard from a lot of companies saying that they are raising prices if you have seen that happen in the market?
The other question that I had was just on the base of buybacks. I think you did $224 million in the first quarter. You've got $921 million remaining on your authorization. I think that runs through sort of the first half of next year, but should we expect you to take that long to use all of that up or would you be doing it faster? Just talk about the pace of share buybacks in the next few quarters.
Tom Watjen - President and CEO
Jimmy, let me just ask Kevin really to speak to your first two questions which really deal with the competitive dynamic.
Kevin McCarthy - President and CEO
Good morning, Jimmy. Well, we've heard some companies talk about making price adjustments and I think we've seen some limited evidence to that but at the same time, we see other companies that continue to be quite aggressive. So in general, I would say there's not been a significant shift in the competitive environment.
We have been consistent with our value proposition. Our prices actually in the marketplace were slightly higher at this time this year than they were last year, so we're maintaining that kind of discipline and focus and we continue to focus on growing in our core marketplace and in the less economically sensitive and risky industries.
So in general, we are focused on sort of delivering our value proposition, our ability to market in the core market and packages with Voluntary Benefits and we're not worrying too much about the price levels right now and we are not seeing much difference.
Tom Watjen - President and CEO
Thank you, Kevin. Rick, do you want to pick up the question on share buybacks?
Rick McKenney - EVP and CFO
Sure, if you look at the first quarter, the $224 million that we did, and you take the remaining authorization of $921 million, you'd see a similar level on average that we would continue to deploy over the authorization period. However I would caution against that because we are going to be very opportunistic in terms of how we buy back stock.
So for modeling purposes, the average is okay. How it actually comes out I think it will be quite different depending on the market environment.
Jimmy Bhullar - Analyst
And by that, you are just implying if you get a better price you would buy more versus other ways?
Rick McKenney - EVP and CFO
Right.
Jimmy Bhullar - Analyst
Thank you.
Operator
Jeffrey Schuman, KBW.
Jeffrey Schuman - Analyst
Good morning, thanks. I'm going to ask a UK question -- or US question first and then I will come back and get in my I guess mandatory UK question. But on the US just kind of a high-level question, as we look a couple years down the road to what we hope is a stronger economy, better employment environment, it seems pretty straightforward there would be top-line implications for you.
How should we think about kind of margin implications? Should we think of you as having better risk margins in that environment or maybe just realizing a little bit of operating leverage in a better growth environment, or should we think about more kind of stable margin expectations versus where we sit today?
Tom Watjen - President and CEO
Kevin, do you want to talk about that as it relates to the Unum US business?
Kevin McCarthy - President and CEO
Sure. Good morning, Jeff. I think as the economy recovers, we get some job growth, we get some wage growth as well, the implications I think would be more significant on the top line in terms of growth of the business, a rejuvenation of sort of MBOC for example and the addition of benefits. And so overall profit levels increase as the top line increases.
As far as margins, you might see a marginal improvement in profit margin, but I wouldn't see a significantly different risk profile than we are managing to right now.
Jeffrey Schuman - Analyst
Okay, so it's mostly a topline opportunity?
Kevin McCarthy - President and CEO
I would say so, yes.
Jeffrey Schuman - Analyst
Okay, on the UK, you made the point several times that you got aggressive on pricing in 2009 and now you are trying to kind of address that. But when I looked at a much longer picture particularly for the disability business, it seems that there's a much longer trend that it's hard not to be concerned about. If we look at disability sales in the UK and assuming I've got all the local currency numbers right, you really only had a modest [lift up] in sales in 2009, 3% sales growth.
Other than that, sales peaked in 2004 and have declined quite steadily since then, in many cases double digits. Premiums this quarter, disability premiums in the UK constant currency I think are 30% below where they were three years ago.
So it appears that there is a long-term trend of giving up disability share in the UK that extends well beyond this period of sort of recent price adjustments. So how do we think about you stabilizing or even reversing that long-standing market share trend?
Tom Watjen - President and CEO
Let me start on that and ask Jack to sort of pick up. First off, I'm not sure the numbers you are looking at, Jeff, but actually I don't believe we have actually lost market share over the last sort of five years. Our biggest challenge, frankly, is that the market isn't growing. I think Jack alluded to it, and he will speak to it, I think, a little bit more when I pass to him.
But this is a market that is substantially under penetrated relative to the US for disability coverage, roughly 10%, let's say. And that 10% penetration rate in the UK has existed for decades. So from a strategic point of view, our biggest issue isn't trying to reshape how much of the pie we own of the existing pie because again at roughly a 50% market share, there is little upside for doing that and that's actually probably one of the things that led to a couple pricing things that we talked about earlier.
Our biggest focus is kind of building a stable foundation to take advantage of the business opportunities that exist today at the same time as Jack alluded to earlier, recognizing the biggest leverage for us is expanding that market share -- the market size from where it is today, so if you take that 10% penetration to 15% or 20%, that's where a lot of our focus is being spent.
It's being spent on working at the policy level with those that are setting policy in the UK government to all the way down to simplifying our product and service offering.
But again, Jack, you may want to speak to that because again, I think we have been fortunate enough to maintain a pretty consistent market share, but the market -- the lack of market growth is really the issue that has constrained our growth and that is really where much of the focus is right now.
Jack McGarry - CEO
Yes, and actually, Tom, since 2002, I believe, our market share went from 30% up to 50%. A lot of that was the result of consolidation in the market. Several key players exiting the market, which we took over their blocks, took over their in-force and got some of their sales from and so that has buffeted the sales. But we have been steady at 50% market share for the last couple of years.
The growth in the market has been severely impacted by the economy in the UK, which took a big hit and has been impacted by pricing in the UK as well. The UK overall sales in the marketplace are down and overall premium levels in the marketplace are down due to both the economy and pricing.
Our position is really solid and the value proposition we have is great. The opportunity -- we have been working with public policy makers. We are looking on a promotional campaign to raise awareness of the need for disability products in the UK to UK workers and we'll look to expand coverage.
One out of 10 -- we have a group of in-force policyholders that are only insuring one out of seven of their employees. If they were in the US, they would be insuring four out of seven, and so that's a tremendous opportunity that we are going to look to capitalize on over the next couple of years. Our goal is to grow the market. It's not to grow market share.
Jeffrey Schuman - Analyst
Okay, that's helpful. Thank you.

Randy Binner, FBR Capital Markets.
Randy Binner - Analyst
Thank you. I guess following up on some comments Tom White made earlier in the call and it's apparent in the financials is that investment income is kind of trending down a bit as investment assets are a bit lower. Just wondering if there's anything that can be done to try and enhance investment income through a borrowing or matched activity? Just we've seen some other life insurers do that. Just wondering if that's something that could be in your playbook to help support your EPS growth goals?
Tom Watjen - President and CEO
Thank you, Randy. Rick, do you want to pick that one up?
Rick McKenney - EVP and CFO
And your suggestions, we look at it but really our investment income will trend very much with our book of business. Our assets are backing our liabilities. We will continue to invest consistently where we have done today on a good risk managed basis. We'll continue to put it in corporate bonds. Today's environment is a little bit tougher given where credit spreads and the interest rate environment is.
But we through prior to the credit downturn, etc., we didn't reach for yield and we're not going to do that today as well to enhance those levels. We are pretty happy with where our investment income, where our investment team has been investing. We have grabbed some asset classes particularly in 2010 which were opportunistic, and we feel very good about the credit quality of those assets. And that would be in the Build America bonds and some tax-advantaged investments, very high credit quality with some good enhanced yields.
But there's not going to be any systematic programs to try and [fuse] our yields with leverage or something like that.
Tom Watjen - President and CEO
If I could add one thing, Randy, because we are a very large corporate bond buyer and corporate bond owner, we will have miscellaneous investment income. There are bonds that get called, get paid, bond call premiums, things like that. Those are hard to predict. They are volatile. Over long periods of time, it's generally pretty steady. We know they are going to come in, but by quarter and by product portfolio it's very hard to predict those.
So it really shows up when you look at the closed disability block, because you've got a flat block of business, and a gentle decline in the overall assets, but we will have volatility quarter-to-quarter because you will get some bond calls one quarter and they won't be repeated the next quarter.
So I think that's just kind of inherent in having as large a corporate bond portfolio and private placement portfolio that we have.
Rick McKenney - EVP and CFO
Maybe, Tom, again we run the risk of over answering, but you may want to speak to the interest margin because again, I think we tend to manage the portfolio for the interest margin. And actually the interest margin continues to be very strong across all our portfolio.
Tom Watjen - President and CEO
That's really kind of the driver of our investment strategy is to have investments that are providing a predictable yield that support the liability discount rate assumptions that we have. So --
Randy Binner - Analyst
All of that is very helpful. I guess just a follow-up then, there's an EPS guidance range that's a percentage growth and it seems like the benefit ratio of Colonial might be a little bit higher. These are all marginal things, maybe a little bit lower persistency at the UK this year if the investment income is just slightly lower than we may have otherwise thought.
Is it possible for you to kind of quantify if we should think kind of middle, lower, upper part of that guidance range, given what we know kind of at quarter end?
Rick McKenney - EVP and CFO
I'm not going to give you more guidance than the range that we have out there already today from our outlook. What I would say on the investment income line relative to your expectations, it may be a little bit lower given some of these tax-advantaged investments which will come out of the investment income line and move to the tax line. You wouldn't know what our tax rate was about 2 percentage points lower than it was a year ago, so there's a little bit of geography going on there as well, Randy.
Randy Binner - Analyst
No, understood on that. It's just it seems like the asset levels are lower but the responses are helpful. Thank you very much.

Eric Berg, RBC Capital Markets.
Eric Berg - Analyst
Thanks very much. Good morning to everyone. Given all of the commentary around the success that you are enjoying in the UK in sort of writing your business, getting pricing right, pricing leadership, losing -- editing the lineup and deleting business that is sorely unprofitable, help me reconcile that with the very significant year-over-year increase in the loss ratio.
Tom Watjen - President and CEO
Rick, do you want to take that one on the loss ratio in the UK?
Rick McKenney - EVP and CFO
Yes, so when you look actually at the year-over-year in the UK, there's a couple things going on. One is last year we would have seen very good results. But you have to dig down underneath that. There is some inflation that's happened over the course of that line and the premium income line has come down. So that's something we talked about earlier which has driven up that loss ratio.
So although it's higher than it was a year ago, quite a bit higher than it was a year ago, it's within our line of expectations that we've seen over the last couple quarters and how we have talked about that book of business.
Eric Berg - Analyst
And in the US, I just want to return to the earlier discussion about claims experience there. I understand from your comments and from reading your news release that the claims incidence is, let's see, was better in the March quarter than it was in the December quarter, but higher than the year-ago quarter. What I am interested in knowing is how does the incidence stack up relative to your expectations?
And in particular, a number of your competitors have reported what they call elevated incidence, which is a term that I interpret to mean it's just not going in line with their expectations. Are -- irrespective of the -- putting aside the issue of comparisons, incidence versus December quarter, incidence versus the year-ago quarter, how is the incidence stacking up relative to your expectations? And are you facing the same sort of negative surprises in incidence that some of your peers are facing?
Tom Watjen - President and CEO
Kevin, do you want to tackle that one?
Kevin McCarthy - President and CEO
Yes. Thanks, Eric. Good morning. On an actual to expected incidence basis, we are performing right where we expect to be and very consistent with our pricing assumptions. We have seen some volatility over the last year and a half in incidence, some ups and some downs, but pretty much in a fairly narrow range of incidence both on a submitted and on a paid incidence basis. So we are not seeing elevated incidence in comparison to some of the others' comments.
As you know, we manage our mix of business. We've moved our mix of business sort of down market, if you will, over the last several years. And actual to expected incidence is performing very well particularly in the smaller end of our book of business, which is the part of the business that is also growing the fastest in our core group business.
And we haven't really seen any volatility in claims by diagnosis or by industry. In fact, incidents has been either slightly improved or basically flat across industry sectors.
Eric Berg - Analyst
That's very helpful. Thank you.

Did you share a natural growth number for the US business for this quarter?
Tom Watjen - President and CEO
Go ahead, Rick.
Rick McKenney - EVP and CFO
Yes, just as we've talked about the natural growth for those of you -- we look at our natural growth in terms of loss of business and what's happening from wage inflation and more lives taken, lives added to different cases. What we have seen over the last couple of years, two years ago was a negative 3%. Last year was negative 1%. Fourth quarter was pretty flat and I'd say we'd probably say the first quarter was pretty flat as well.
So we're looking forward to the economy recovering. We haven't seen it naturally coming through in some of those metrics that we look at.
Mark Hughes - Analyst
Then your sales in the group long-term disability up nicely this quarter. Was there anything unusual, any new initiatives on the marketing front or channel front that contributed to that? Should that kind of growth -- any reason that wouldn't be sustainable going forward?
Tom Watjen - President and CEO
Kevin, do you want to --?
Kevin McCarthy - President and CEO
Good morning, Mark. No new initiatives at least specific to the quarter. We have been steadily rolling out our Simply Unum platform, the ability to package our products together for more efficiency on the benefits buying side for the employer, stronger employee communications and support for the employers. And we have more and more brokers in the marketplace selling packages of LTD with Voluntary Benefits. And I think all of those kind of factors and the investments we have made strategically are paying off.
And I think that in general you know we should see solid core market growth coupled with strong Voluntary Benefits growth, but I do think you'll see some volatility from quarter to quarter sort of within lines. It won't always be LTDs up 7 and Life is 5 or Life is up 8. It will bounce around a little bit depending on sort of what's out there in the marketplace in terms of [out to bid] activity.
Tom Watjen - President and CEO
Thanks, Mark. I know we are running a little bit late but we had a couple more questions in the queue, so we will take those before we close. So operator, let's just go with the next couple of questions that are in the queue.
Operator
Chris Giovanni, Goldman Sachs.
Chris Giovanni - Analyst
Good morning. Thanks very much. I just wanted to focus on capital. I guess first, you've typically used the mid-May sort of Board meeting as an opportunity to increase the dividend 10% plus. And I just wanted to see if this was still the expectation again this year? Does the emphasis on share repurchases that you started last May sort of mute the likelihood of this pace of dividend increase?
Tom Watjen - President and CEO
Rick, do you want to cover that?
Rick McKenney - EVP and CFO
Certainly. On the dividend I think you're right, it is a topic of discussion with the Board pretty consistently but May over the last couple of years has been a decision point time. Given the capital position that we are in today, I think those discussions are really on two different sides. One is going to be the capital that we take out through recurring dividends that we see coming off our operating income. We will discuss that but it does not in any way impact the amount of capital we have available to ourselves for the share repurchase. So I wouldn't necessarily say that one excludes the other.
Tom Watjen - President and CEO
I would echo that, Chris. I think that we view both dividends and share buybacks as two sort of very necessary tools to put that excess capital to work and the fact that we do one versus another, I think we look at those as both very important creators of value for our shareholders.
Chris Giovanni - Analyst
Okay, thanks. Next just in terms of debt maturity, you obviously just did the piece in March retiring the $225 million, so now you're looking out to 2015 before the next debt maturity of about $300 million. With the leverage ratio where you sit today sort of just below 21%, is there any talk of potentially taking that up here in the near term?
Rick McKenney - EVP and CFO
I wouldn't say that given what rate they are running at that we would take it up for any specific opportunity that we would have out there to deploy debt and capital via the M&A markets or anything else. But you are right, as we look out over the next couple years we will see a natural deleveraging which we don't need to have. We're at a very low leverage ratio today and so you'd probably see us be consistent right around that 20% level in the wake of not doing something else with debt.
Chris Giovanni - Analyst
Okay, thanks so much.
Operator
John Nadel, Sterne, Agee.
John Nadel - Analyst
Thanks for extending. Appreciate it. Just a couple real quick ones. Just to follow up a little bit on the January renewal season and pricing trends from I think an earlier question, just wondering if you dissect that a bit more and think about size, plans, small-market, midmarket, etc., whether you would see anything different happening in either or in any of those markets vis-a-vis the other?
And then the only other question I have that is left over is just to think about the tax-advantaged investments that you guys have been making and how to think about what that does to your tax rate as we look forward, tax equivalent yield, that sort of thing?
Tom Watjen - President and CEO
Thanks, John. Kevin, do you want to speak to the renewal season?
Kevin McCarthy - President and CEO
Yes. Good morning, John. I think it has been a pretty sort of uneventful kind of renewal season. We went into renewals during the fourth quarter last year looking forward to the first quarter of this year thinking that if prices in the market didn't harden that we might be under some pressure. That hasn't for the most part really materialized. I think we are feeling very successful with our renewal program. We are I think slightly ahead of plan relative to what we want to be right now.
And out to bid levels are actually lower at this time this year compared to the same time last year. So I think we are feeling pretty successful about our renewal program right now.
Tom Watjen - President and CEO
Rick, do you want to take the tax advantage (multiple speakers)?
Rick McKenney - EVP and CFO
I will take it.
Tom Watjen - President and CEO
I was going to take it myself, but I thought I would leave it with you.
Rick McKenney - EVP and CFO
It's always good to have a tax question be the last one on the call.
John Nadel - Analyst
Sorry, bad timing.
Rick McKenney - EVP and CFO
When you look at our tax rate, actually what you saw in the quarter about 31.5%, we see it probably a little bit higher than that, just slightly higher than that over the course of the year from a planning perspective.
Specific to the investments, we were very active last year in tax-advantaged investments. We saw very good returns. Those returns have come in quite a bit here over the last six months as a lot of other players who were out of that market are getting back into it. So we will still do some of those but it's not quite the rich yields that we saw. And you will see our tax rate, as I say, kind of blend in, slightly higher, but about the level that it's at today.
John Nadel - Analyst
Okay, so we are definitely seeing that sustainable at a lower level at least relative to the last couple of years. Got it. Thanks very much, guys.
