Good day ladies and gentlemen, and welcome to the second quarter 2010 Laboratory Corporation of America earnings conference call. My name is Crystal, and I will be your operator for today. At this time, all participants are in listen-only mode. Later, we will conduct a question and answer session. (Operators Instructions) As a reminder, today's conference is being recorded for replay purposes. I would now like to turn the conference over to your host for today, Mr. David P. King, Chairman and CEO of LabCorp. Please proceed.
David King - Chairman & CEO
Thank you. Good morning and welcome to LabCorp's 2010 second quarter conference call. Joining me today from LabCorp are Brad Hayes, Executive Vice President and Chief Financial Officer; Ed Dawson, Senior Vice President and Chief Accounting Officer; and Steve Anderson, Vice President Investor Relations. This morning, we will discuss our second quarter 2010 results, highlight a few of our strategic initiatives, and provide answers to several frequently asked questions. I would now like to turn the call over to Mr. Steve Anderson, who has a few comments before we begin.
Steve Anderson - VP & IR
Before we get started, I would like to pointed out there will be a replay of this conference call available via the telephone and Internet. Please refer to today's press release for replay information.
This morning, the Company filed a Form 8-K that included additional information on our business and operations. This information is also available on our website. Analysts and investors are directed to this 8-K and our website to review this supplemental information. Additionally, we refer you to today's press release, which is available on our website for a reconciliation of non-GAAP financial measures discussed during today's call to GAAP.
I would also like to point out that we are making forward-looking statements during this conversation call, and these statements are based upon current expectations, and are subject to change; including, based upon various important factors that could affect the Company's financial results. Some of these factors are set forth in detail in our 2009 10-K and subsequent filings. The Company has no obligation to provide any updates of these forward-looking statements even if our expectations change. Now, Brad Hayes will review our financial results.
Brad Hayes - EVP, CFO & Treasurer
Thank you, Steve.
By now you should have had a chance to review our second quarter financial results. On today's call, I will discuss four key measures of our financial performance--cash flow, revenue growth, margin, and liquidity.
First, cash flow. Our cash flow trends remain excellent. Free cash flow for the trailing 12 months ended June 30, 2010, increased 19.6% to $800 million, compared to $668.8 million in to 2009. In each case, net of transition payments to United Healthcare. We are extremely pleased with our cash collections. DSO improved five days year over year to 45 days at the end of June. As a result of our continued success in cash collections, we reduced our bad debt rate by 25 basis points to 4.8%. We are very proud of the LabCorp employees who have made this success possible through their diligent focus on getting paid for the services we provide.
Second, revenue growth. Revenue increased 4.2% year-over-year in the second quarter. During the quarter, we achieved strong growth in revenue per requisition, which increased 6.3% year-over-year. The growth in revenue per requisition is attributable to mix shift, increases in test per requisition, and rate increases. The revenue growth for requisition was also impacted by the Canadian exchange rate, Monogram, and the lost government contracts, which together improved revenue per requisition by 3.3%. Total Company volume decreased 2% year-over-year. Excluding Canada, volume decreased 2.1% year-over-year. The termination of two large government contracts at the end of the second quarter 2009 reduced volume by 2.4%. Excluding the lost contracts, volume increased by approximately 0.3% in the quarter. Esoteric volume increased 4.9% in the quarter.
Third, margin. For the second quarter, our operating income margin was 21.8%. This margin increased 40 basis points year-over-year due to reductions in bad debt expense and operational improvements. Margin expansion was hindered by costs associated with recent transactions and acquired assets that are not yet integrated.
Fourth, liquidity. We remain well capitalized. At the end of June, we had cash of $103.8 million, and approximately $430 million available under our revolving line of credit. At the end of June, total debt was $1.3 billion, including $30 million drawn down on our revolving credit facility. During the quarter, we repurchased $116 million of stock, representing approximately 1.5 million shares. At the end of June, approximately $100.1 million of repurchased authorization remained under our previously-approved share repurchase program.
This morning we updated our 2010 financial guidance. We expect revenue growth of 4.5% to 5.5%, compared to previous guidance of 2.5% to 4.5%; adjusted EPS, in the range of $5.40 to $5.55, compared to prior guidance $5.35 to $5.55, excluding the impact of any share repurchase activity after June 30, 2010; operating cash flow of approximately $870 million, excluding any transition payments made to United Healthcare, and capital expenditures of approximately $135 million. Finally, while we do not provide quarterly guidance, we want to remind you that the fourth quarter is always our softest quarter from a topline and earnings perspective, due to the impact of the holiday season on volumes.
I'll now turn the call over to Dave.
David King - Chairman & CEO
Thank you, Brad.
We are very pleased with our second quarter results. Despite continued challenging economic conditions, we grew revenue by 4.2% in the quarter. We also grew esoteric revenue by approximately 5%. Revenue per requisition remained strong, increasing 6.3%. Taking into account the previously lost contracts, volume increased by approximately 0.3%. And we generated operating margin expansion of 40 basis points due to our continued improvement in the bad debt expense, and our focus on automating and optimizing our labs and patient service centers. Margins would have been higher but for the factors Brad Hayes mentioned.
I would like to mention the performance of the many LabCorp employees working in our billing operations and patient service centers. Beginning in the third quarter of 2008, over 6,000 people have maintained a disciplined focus on getting paid for the valuable services we provide. They have performed exceptionally during a very tough economic environment, and our declining DSO and bad debt expense reflect this. We are very proud and appreciative of their efforts.
I would now like to update you on a few of our strategic initiatives. First, we continue to take advantage of attractive acquisition opportunities. On June 14, we acquired the assets of DCL, a full service clinical laboratory located in Indianapolis with a strong specialized women's health offering. This acquisition furthers our strategy of growing in large metropolitan markets, and enhancing our disease state-focused offerings. On June 16, LabCorp acquired certain assets of Westcliff Medical Laboratories, a clinical lab in California, pursuant to the asset purchasing agreement and an order of the bankruptcy court administering the bankruptcy of Westcliff. This acquisition furthers our strategy of growing in the California market, where we have historically been underrepresented.
LabCorp was notified by the Federal Trade Commission that it intended to review the acquisition, and on June 24, we entered into an agreement with the FTC to hold the Westcliff business as an independent laboratory, separate from LabCorp while the FTC conducts its review of the transaction. LabCorp is working with the agency to complete the review as quickly as possible. We are unable to provide further color on the impact of the transaction until the conclusion of the FTC's review.
Second, effective August 1, 2010, Empire BlueCross BlueShield, New York's largest insurer by membership, is expanding its reference laboratory network to include LabCorp in all of its markets and products. This expansion provides broader choice for Empire's members and physicians, reduces member costs associated with out of network laboratories, and creates a more competitive environment among labs. We are excited about the opportunity to work closely with Empire and its members, and to provide them with greater choice, and exceptional lab service.
Third, we recently launched our new on-line gateway for client lab connectivity called LabCorp Beacon, accessible anywhere and at any time, LabCorp Beacon is an end-to-end solution that allows physicians to view, share, manage, and analyze lab results. Beacon was developed with significant customer research and input, and offers a user-friendly interface, and sophisticated tools that will help our customers streamline office work flow and information sharing. LabCorp Beacon will enhance our connectivity portfolio as the solution of choice for direct client connectivity.
We will continue to offer physicians a choice of tailored solutions including robust integration with EMRs, EHRs, and PHR applications. These options allow our customers to choose the right solution based on their needs for decision support, interoperability, and their meaningful use objectives. LabCorp Beacon represents our ongoing commitment to innovate and invest strategically in our IT capabilities while maintaining our open platform approach. We have rolled out Beacon to a select group of our customers, and they have received it enthusiastically. We will continue to roll out Beacon throughout the year.
Fourth, we continue to execute on our 2010 initiatives that have now driven year-over-year gross margin improvement for three consecutive quarters. These initiatives are even more important in light of the passage of the Healthcare Reform legislation, which he we believe will drive business in all sectors of healthcare to the most efficient and lowest cost providers. Our Protedyne subsidiary continues to provide innovative solutions for automating and streamlining our operations. We are rolling out next generation appointment scheduling, and we continue to optimize the work flow in our patient service centers to improve the customer experience as well as the overall efficiency of our business.
As a result of our agreement with Sysmex America Inc., we have fully automated hematology operations in our regional core laboratories throughout the United States. The Sysmex partnership allows to us increase through-put with less labor, and to improve turn around time for our customers. It is one of the largest laboratory automation projects ever undertaken.
This is just a sampling of the many initiatives we have underway to increase efficiency and improve service. They will remain an important strategic focus for us in the months and years ahead.
In summary, we are pleased with our second quarter performance and remain very excited about our future growth opportunities and the strategic initiatives that will help us capitalize on them.
Now, Steve Anderson will review anticipated questions and our specific answers to those questions.
Steve Anderson - VP & IR
Thank you, Dave.
Can you update us on the mix of your business coming from esoteric testing? In the second quarter, approximately 36% of our revenue was in the genomic, esoteric and anatomic pathology categories. Our goal over the next three to five years it is to increase our esoteric test mix to approximately 40% of revenue.
What are your plans for uses of free cash flow during 2010? We remain committed to returns value to our shareholders; first by using our free cash flow to grow our business through strategic acquisitions and licensing agreements, and second through continuing our approved share repurchase program. The acquisition market remains attractive, with a number of opportunities to strengthen our scientific capabilities, grow our esoteric testing franchise, and increase our presence in key geographic areas. Historically, we have been a consistent buyer of our own shares. Since the beginning of 2006, the Company has repurchased approximately $2 billion worth of its stocks.
Can you remind us of how drugs of abuse volume trended during the year. In the quarter, our drugs of abuse volume increased 15.4% year-over-year. That compares to a year-over-year increase of 6.8% in Q1 of 2010, and year-over-year decreases of 6.5% in Q4 of 2009, 15% in Q3 of 2009, and 19% in Q2 of 2009.
What is the status of your transition payments to United Healthcare? In the quarter, the Company was billed $1.1 million in transition payments, and paid $2.1 million in transition payments. As a reminder, our obligation to reimburse United Healthcare for transition payments ended on December 31, 2009. We have received the final invoices for these payments, and the final amount is approximately $120 million.
What impact would the proposed 2011 Medicare physician fee schedule rule have on your business? Assuming the Congress acts to prevent the conversion factor production within the proposed Medicare physician fee schedule rule, we would expect to receive a modest increase to our revenue tied to the physician fee schedule. As a reminder, approximately 2% of our revenue is tied to the physician fee schedule.
Now, I'd like to turn the call back over today.
David King - Chairman & CEO
Thank you, Steve. In summary, we are pleased with our performance in this quarter, and are optimistic about our business in 2010 and beyond. Thank you very much for listening. We are now ready to take your questions.
Operator
(Operator Instructions) And your first question today comes from the line of Robert Willoughby with Bank of America Merrill Lynch. Please proceed.
Robert Willoughby - Analyst
Hello, Dave. What realistically can you accomplish on the acquisition front? It looks like the pace has really picked up here? Can you bang out three or four more of these type tuck-in deals, or operationally or logistically is that just tough to accomplish, and does a Genzyme opportunity potentially freeze you here?
David King - Chairman & CEO
The tuck-in deals are generally organized, managed, and integrated through the divisions, Bob. So, we have a good deal of capacity to continue to do them. Obviously, the bigger they are, the more complex they become, but the smaller fold-in deals really are divisionally driven, and we have quite a bit of band width there. Obviously a deal like the Genzyme genetics deal would be a large deal. It's a much more national deal in scope because of the breadth of their business. So, it would require a good deal more lifting, but it certainly doesn't freeze us or prevent us from doing the fold in deals concurrently.
Robert Willoughby - Analyst
So, a reasonably full pipeline we should expect to see more announcements over the course of the year?
David King - Chairman & CEO
Yes. I think--I mean, again, we want to remain disciplined and be--and be focused on valuation metrics, accretion dilution profile, but I think it's--I think it's reasonable to expect that we're going to continue to make acquisitions as long as the opportunities are attractive.
Robert Willoughby - Analyst
And anything to from an early read on Healthcare Reform as yet? Is that resulting in more dialogues for you with better quality assets, or any change you can glean from that effort as yet?
David King - Chairman & CEO
I think there's more interest from--from lab owners who potentially see Healthcare reform in the next 24 to 36 months having an impact on their-- particularly on their revenue structure and also on their expense structure. So, labs that are getting a substantial amount of their revenue from Medicare are facing five years of payment cuts pretty much regardless of what the CPI does, and, there certainly is pricing pressure from other fronts, as well. So--and the inflationary side of the cost factor with wage inflation and other things doesn't go away. So, I think we're having good discussions with a number of owners of quality assets, and, again, it's going to come down to how do we feel about valuation. Is it accretive or dilutive? How does it fit with our strategy? A I mentioned, both DCL and the Westcliff with important strategic initiatives, greater size in major metropolitan areas, greater strength in disease state focused. And particularly, we've been so small in California for so long that the opportunity to make a modest acquisition there was very attractive to us.
Robert Willoughby - Analyst
And another question, what are your competitors--obviously your large competitor indicated pricing seem now part of their strategy to grow. Is this--have you noticed any change in the base of competition for managed care or other contracts?
David King - Chairman & CEO
Well, I think the-- first of all, pricing has always been very competitive and very tough in our industry, and we shouldn't suggest otherwise. And everybody who does business with healthcare providers of any kind, whether it's labs, doctors, hospitals, always wants more services for less money. That's inevitable. So, I don't think the pricing environment has changed particularly in the last 12 to 18 months. We said last year that we had gone out, and made some important contractual renewals with WellPoint, with Cigna, with some of our--of our regional plans. And we also have pointed out that with United Healthcare, we have a 10-year contract, and they have been a terrific partner, and we continue to grow that business. So--so I-- we're not--our strategy is not to lead with price. Our strategy is to be disciplined on pricing. Our strategy is to complement organic volume growth with acquisitions, and our strategy is to continue to, with innovations like our LabCorp Beacon platform and other IT innovations that are coming, is to continue to differentiate ourselves by making it easier for the doctors and their patients to do business with us. So, I know that was a long answer, but the short answer to the question is there will be pricing pressure. There will be impacts on price for the reasons Brad mentioned. You will not see the kind of pricing the rest of the year that you're seeing this quarter, simply because we're going to annualize Monogram, we're going to annualize the lost contracts as drugs of abuse testing grows. That has a downward pull on price, but we feel good about where we are on pricing, and we feel good about the contractual relationships that underpin our pricing.
Robert Willoughby - Analyst
That's good. Thank you.
David King - Chairman & CEO
Thank you.
Operator
And your next question comes from the line of Adam Feinstein with Barclays Capital. Please proceed.
Adam Feinstein - Analyst
Thank you. Good morning, everyone.
David King - Chairman & CEO
Good morning.
Adam Feinstein - Analyst
Hello, Dave, maybe just a starting point since you were talking about the pricing of managed care, obviously a lot of interest after yesterday. And I guess just wanted to get your feedback, you had said there's always competition, there's always issues with managed care, but the feeling over the last 24 months is that things were very stable on the managed care side. So, just want to get some clarity whether you think that is still the case, and even though we've seen some--some bigger contracts and some news, and you mentioned Empire as an opportunity earlier, but just certainly--just wanted to get clarity in terms of would you characterize this as a more stable environment for managed care than it was a couple of years ago?
David King - Chairman & CEO
I think it's about the same, Adam. I don't--I don't think it's gotten measurably better and I don't think it's gotten measurably worse. I think since the repricing in 2007, pricing generally has been pretty stable. Again, everybody always wants more service for less price, but I haven't--I don't think we've seen any major change in the managed care dynamic from a pricing perspective.
Adam Feinstein - Analyst
Okay. Great. And then maybe just on the Empire opportunity, could you talk a little bit about that, just how--how are you guys thinking about that? Is there anything included in guidance for that? If you can't given any point-on numbers, I totally understand, but just want to get a general sense in terms of are you guys assuming any benefit from Empire?
David King - Chairman & CEO
You know, the opportunity starts on August 1, and so given the--given the transitional nature of it for this year, I don't think the benefit will be huge. It is incorporated into the guidance. I don't think you're going to see meaningful change in the numbers based on Empire. Now, that's this year. I do think, as we--one of the obstacles that we have had in the New York market, in terms of fully capitalizing on the great benefits we got from the United and Oxford relationship, is that physicians have not been able to send us their Empire work. And so, I think over the long term WellPoint's decision to broaden the provider network to include us is going to have a significant benefit for us. But it's not--I don't expect it to be anything big in the numbers that you'll see in this year, and it is part of the guidance that we've given.
Adam Feinstein - Analyst
Okay. Great, and then just a final question here. Just thinking more about the core business, pricing growth has been very strong. You talked about some of the drivers there in terms of just mix and such, and we should anticipate the same rate of growth, but how should we think about normalized growth in terms of the core business? So, in terms of what you guys report as all in pricing how--how should we think about it in terms of a more normalized number?
David King - Chairman & CEO
Just from a pricing perspective?
Adam Feinstein - Analyst
Yes, so I guess the 7.2%, and I guess that--I guess that includes mix, also. So, I guess it's just, you know, revenue per session.
Brad Hayes - EVP, CFO & Treasurer
Yes, Adam, this is Brad. I think that has a lot of things going on in the loss contracts were of a core nature. So, a number of things that we mentioned that are having a positive lift on price, I think, will obviously come down over time. You know, what I would expect to see there is a very low single digit number in a normal environment. There are--there is some what I call mix within mix that can happen in that line, where some tests that are greater or lower than the average price might be growing or shrinking faster than others. But I think there's a lot of lift in that number right now, due to some of the factors that we've mentioned.
David King - Chairman & CEO
Yes, Adam, it's Dave. I think what we have always said, and I don't really think it's any different, is real price, that is, unit pricing year-over-year, is going to be zero to maybe 50 basis points. Mixed base pricing is going to be 1% to maybe 1.5%, which obviously isn't the core, that includes--includes higher esoteric mix. So, that's how we get to a sense of we expect pricing growth in a normalized environment to be 2% over time, but again, real unit price growth is going to be relatively flat to maybe 50 basis points.
Adam Feinstein - Analyst
All right. Thank you very much. Appreciate it.
Operator
And your next question comes from the line of Amanda Murphy with William Blair. Please proceed.
Amanda Murphy - Analyst
Good morning. Just a couple of more questions on the managed care situation, if I may. I guess first, Steve, would you ever consider any kind of early renewal process, and if so, what would be the advantages in your mind to that type of program?
David King - Chairman & CEO
Well, we've already done our early renewals. We did them in 2009. And the advantage of early renewals is greater visibility on price and volume in a--as you look out a couple of years ahead, so it helps you plan the business. I think--I think the reality is, with these -- particularly with the larger payors, we're always in discussions about the contracts, and we're always in discussions about how we can enhance the opportunity. So, WellPoint is a good example with Empire. I mean, we've been in those discussions for a long time about our desire to help them by offering more choice for patients and physicians in the New York market. So, we're always talking to managed care about contracts, and when the opportunity arises to renew contracts prior to the termination date on their --on favorable terms, and when I say favorable terms, I mean favorable for both parties. Obviously, they want to get something out of it, too, and part of what they get is some certainty about their provider network and coverage, and how many patient service centers are going to be close to their patients. We would certainly do that.
Amanda Murphy - Analyst
Okay. And then I think when we went through this repricing effort a couple of years ago, a few years ago, that there was some effort to sort of strengthen the language around the ability to terminate those contracts, which I think is what was in part the facilitator of the industry-wide event. Am I remembering that right? Or not.
David King - Chairman & CEO
I'm not sure I follow. I'm sorry, Amanda.
Amanda Murphy - Analyst
I guess I recall that there was some effort to remove--I guess there was language in the contract that allowed a plan to terminate a contract with notice, and that kind of drove the whole industry-wide events in 2007, and there was an effort to maybe have it be more--that Health Grand just couldn't come and do that, that it was more collaborative. Maybe I'm not remembering that right.
David King - Chairman & CEO
Yes, I --
Amanda Murphy - Analyst
Okay. That's fine. Alright. So, switching to the volume side of things. If you look at the core business, the numbers were a little bit better than last quarter, so I'm curious if there's--that's just an easier comp sort of situation, or have you seen anything, you know, improving sequentially? And then just also, it seems generally that you're doing better than maybe IMS data would suggest. So, would you even go as far as to say you're gaining share in some segments?
Brad Hayes - EVP, CFO & Treasurer
Amanda, this is Brad. I agree on your observation on the core improvement. I would just like to remind you there was weather in the first quarter, and no weather in the second quarter. I think that's the biggest driver. As we look at the business, second quarter compared to first quarter, and consider a number of factors, many of which we've mentioned in terms of the lost contracts and the like, we think the business performed in the second quarter very similar to the way it performed in the first quarter. And as we look at IMS data, those visits are obviously down more than the volume that we are experiencing. So, I would like to say that that is a tribute to our strategy, and the fact that potentially we are taking share. But it's very hard to draw direct conclusions from that information. I think it is directional, and we certainly pay attention to it, but like to see us performing better than that directional piece of information.
Amanda Murphy - Analyst
Okay. Thanks a lot.
Operator
And your next question comes from the line of Gary Lieberman with Wells Fargo. Please proceed.
Gary Lieberman - Analyst
Thanks, good morning.
David King - Chairman & CEO
Good morning.
Gary Lieberman - Analyst
Maybe talk about some of the in-sourcing trends that you're seeing, maybe specifically on the anatomic pathology side, and what you guys have been able to do to compete there?
David King - Chairman & CEO
Sure. Obviously the--we're pretty transparent in the disclosures in our 8-K about this, so you can see that we did--we did continue to have a downward trend in the anatomic pathology volumes; however, the rate of decline has slowed. And so, as I mentioned on the call last quarter, Gary, I think we've seen the big impact from this in--in the end of last year and the beginning of this year. The major areas where we're seeing in-sourcing or-- in the urology, and I guess particularly in the urology and now in the dermatopathology, where physicians are setting up their own internal laboratories, and are making arrangements with pathologists to do their reads. And, from a competitive perspective, what we've done is focused on the fact that when you send your specimens to LabCorp, you get specialized pathologists. You don't get general pathologists reading these specimens. So, that's very important for patient care, that you have a uropathologist, or a dermatopathologist reading these specimens, not just a general pathologist. We focused on the full menu of services that are available from LabCorp; special stains and other more sophisticated techniques that are not necessarily available at internalized physician labs. Again, we focused on the IT solutions and capabilities that we offer that are not available in the internalized labs, and the ability to perform other tests on the specimens. We also have continued to point out to regulators that there is a high potential for abuse in physician in-sourcing, that the number of--for example, the number of biopsies on a prostate typically increase, and increase fairly significantly after physicians in-source, and that adds expense to our healthcare system at a time when we're trying to make healthcare expenses go the other way. There are also concerns about physician's self interests and conflict of interest, and concerns about quality of patient care. So, we continue to point those things out to the regulatory authorities, and we have had support in that from our own trade association, from the College of American Pathologists, and from other influential trade associations that have interest in the lab industry. So, I said in the first quarter, and I continue to say in the second quarter, we need to pick up our--the level of competition. We need to pick up our game here, but, at the same time, I'm pleased to see that the trend has ebbed a little bit in terms of the pathology volumes going down.
Gary Lieberman - Analyst
Great. Maybe one quick follow-up on price. I guess you said that most of your contracts, or that in 2009, you started to term out some of the contracts. Be interested to know if because of any incremental price competition any of those--those contracts have come back or--and tried to renegotiate based on maybe better prices that they're getting elsewhere?
David King - Chairman & CEO
I--I think--I think pricing discussions between us and our large customers are really something that we should not spend a lot of time talking about publicly. We're very, very happy with our relationships with United, who, as I mentioned, has been a terrific partner. With WellPoint, which has been our national sole strategic partner, with Cigna, with Humana. And these contract extensions processes have been--and I don't mean to overlook anybody else with Horizon, with the Texas Blue Plan, with all of the plans that we do business with--these contract negotiations are always--there's always discussion about pricing. But I think it's--suffice it to say that we have contracts, our managed care partners have shown no indication that they plan not to honor the contracts, or that they want to rediscuss the contracts. And so, I--I just think we need to look at this as I don't see anything that has changed from where we were last year, from where we were in 2008, which is the payors always want to pay less for more, and we always want to get paid more for the value that we provide. And that's the way the dynamic is going to be probably as long as I'm around here.
Gary Lieberman - Analyst
Okay. That's very helpful. Thanks a lot.
Operator
Your next question comes from the line of Tom Gallucci with Lazard Capital Markets. Please proceed.
Tom Gallucci - Analyst
Good morning. Thanks. Just a couple of quick follow ups on some things that have already been discussed. I guess in the revenue guidance raised there, you have obviously done some acquisitions. Any other moving parts we should be aware of that drove that?
David King - Chairman & CEO
Tom, it's Dave. I think the increase in the revenue guidance is largely to incorporate the impacts of the acquisitions, plus the potential Empire opportunity.
Tom Gallucci - Analyst
Okay. And then you obviously said before, when you talked about acquisitions remaining disciplined and things, looking for the sort of right opportunities, accretion, dilution-wise, could you characterize the pricing expectations out there on behalf of sellers compared to where we were maybe a year ago, or the competitive landscape versus other potential buyers, and what that is doing to pricing?
David King - Chairman & CEO
I think it depends on which sellers. There are still some sellers who still have high value--high expectations on valuation. There are others who I think have more realistic expectations. So, I think the--I think expectations--if I--if you sort of think of it as in a global what do people think they should get for selling their asset, I think expectations have trended down from where they were in 2008 and 2009. So, that's part of the reason that we have become more active, is because the assets are available at valuations that are increasingly attractive.
Tom Gallucci - Analyst
Right. Last thing, I'm sorry if you commented on it and I missed it, but obviously there's been some talk out of the FDA about increasingly sort of regulating testing. So, just curious what your thoughts were there. Thanks.
David King - Chairman & CEO
Sure. As I think you know, there was a two-day meeting earlier this week, and--regarding FDA regulation of laboratory-developed tests, and also the FDA's regulation of direct to consumer genetic testing. And there's also a hearing this morning, the Energy and Commerce Committee is having a hearing on direct to consumer genetic testing. I think this is an area in which there is increasing regulatory focus, and I--I think that in various discussions with the FDA, their view is there is a need for some greater oversight of laboratory developed testing. Their view is also that they do not want to do anything abrupt or without thorough deliberations. So, my sense is that there is going to be greater oversight, in some form or another, of lab developed testing. I think there will probably be greater oversight of direct to consumer testing, particularly direct to consumer genetic testing, and our goal is to work collaborativelily with FDA to make sure that whatever regulatory activity they undertake, takes into account the importance of laboratory-developed testing. The importance of the laboratory's ability to innovate and bring tests to market rapidly, that people need, without having to go through the whole process of a kit or of a lengthy regulatory review. So, I think this is an evolutionary process, and we're--we're very much committed, both LabCorp and the American Clinical Laboratory Association, are very much committed to working collaboratively with the FDA to coming out with the right answer.

And your next question comes from the line of Kevin Ellich with RBC Capital Markets. Pleased proceed.
Kevin Ellich - Analyst
Good morning. Just a couple of questions. Just following up on the guidance, is Westcliff included in the guidance? I'm just trying to get clarity on that.
David King - Chairman & CEO
Yes, Westcliff is included in the guidance. Now, be to be clear, because of the situation with the FTC, we are not able to integrate Westcliff into our western operations while the review is pending. So, Westcliff is included in the guidance, and it is a positive to revenue, but it is actually a negative to EPS because of their expense structure, which we can't change until the FTC finishes its review of the transaction.
Kevin Ellich - Analyst
I got it. Okay. That's helpful. And then, Dave, you know thing you've talked about in the past is Canada, and you've been pretty positive on that. It sounds like there's been some more consolidation, especially in the province of Alberta on the pathology testing, or cervical cancer testing. Just wondering, is that a good opportunity for you? Is that a positive for LabCorp?
Brad Hayes - EVP, CFO & Treasurer
Kevin, this is Brad, and I do think it's a positive. As a reminder, that business is--our business in Alberta is not consolidated. So, you see the earnings from that down below the operating income line. But it's still a business that we are very much interested in and stay in touch with. And I think it is a good signal in Canada, and it really applies to our market, as well, that getting testing into the best provider in terms of cost and quality, is good for the system.
Kevin Ellich - Analyst
Got you. Okay. And since I have you, Brad, just wondering about the margins. Obviously we've seen a very nice improvement on DSO, and also bad debt. Just wondering how much lower can bad debt really go? I mean, we've seen a pretty big improvement here.
Brad Hayes - EVP, CFO & Treasurer
Right. And we still see opportunity. Obviously, as we look at our initiatives, we're still making progress, but we're not a hundred percent successful yet. So, I think the to opportunity is there to potentially decrease in the future. As we've said in the past, we would like to lead the industry in most categories of metrics, and that's one that we keep an eye on, as well.
David King - Chairman & CEO
Kevin, it's Dave. Just one further comment on that, because I think it's important that we be clear about this. When we set our bad debt rate, we set it based on a 12-month going forward projection of what we think bad debt is going to be. So, if we adjusted bad debt to the inverse of the collection rate every quarter, you would see a much broader fluctuation, and it would go up and down depending on what top line revenue in the quarter was, and the collection experience. I think from the standpoint of the predictability of earnings and the predictability of our business model, that the way that we do it is more desirable, which is, we try to figure out what we think bad debt will be for the next four quarters, if not beyond, and that's where we set it. So, when we started the year, we thought that bad debt would continue in that 5% range, and, as a result of collection experience and as a result of the initiatives that we have had in place, now we think that for the next four quarters, it's going to be sustainable at the 50 basis points lower.
Kevin Ellich - Analyst
Understood. Thanks for the explanation. You know, thinking about the big picture changes in the US healthcare landscape, just wondering which areas you're still focused on. Is it infectious disease? Any specific testing category? And then, maybe more broad thoughts on international expansion. Is that still in the works some point? And there was some chatter about Sonic. Just wanted to see if you had any opinion about that?
David King - Chairman & CEO
Well, I think Sonic is a terrific company, and a very good competitor, and they have businesses in a lot of places that we don't know anything about. So my--do we have international aspirations? Obviously, we have the Canadian business, and as Brad has mentioned, that's an attractive business and it's a business we would like to continue to grow. We've said for a considerable period of time that our clinical trials business, which is doing very well this year, after a tough year last year, when the whole CRO industry was under a lot of pressure, we've said that we have broader international aspirations for our clinical trials business and being able to provide services, clinical central lab services, central lab services, I should emphasize, in some countries where we don't have a presence now, or where our presence is through some collaborative arrangement. Beyond that, in terms of broad international aspirations, I'll reiterate what we've said for a long time, which is that we--we think there is a great opportunity in the US, and that's where we're going to continue to focus. In terms of overall thoughts on healthcare reform, with my thoughts on healthcare reform and a couple of bucks, you can buy a cup of coffee, but my thoughts on healthcare reform are, there is going to be a great deal of pressure to bring down costs. And there's going to be a great deal of pressure on providers to become more and more efficient. And the good news from LabCorp's perspective is the 2010 initiatives, the IT investments, which will be extremely important to physicians. I read over the meaningful use regulation that came out. I think there are 20 criteria that physicians have to meet for meaningful use, and then there's a menu of another 15, and I think they get to pick 5 of those. So, the automation and efficiency, the IT investments, the continued innovation in improving customer service, are all going be to our benefit. And I think, if you saw the newspaper this past weekend on Sunday, there was a front page article about how insurers are offering narrower networks as a way of reducing or holding down or not increasing premium costs to employers, and those narrower networks are going to be focused on the lower cost providers, and we are the lowest cost provider in our industry. So, as long as we continue to remain--as long as we continue to improve efficiency and we continue to improve our overall interoperability, IT capability, service levels, efficiency of our business, I think we're going to be in good shape.
Kevin Ellich - Analyst
No, that's helpful, Dave. I guess to just follow up on that point, though, if you guys are the lowest cost providers, and assuming your big effort competitor is, also, what's the logic or rationale behind renegotiating the contracts early to--managed care contracts early, and taking lower price now when you guys have the size and scale, and are already the lowest cost provider? Any thoughts behind that?
Brad Hayes - EVP, CFO & Treasurer
I think that was a question for yesterday's call.
Kevin Ellich - Analyst
Got you.
Brad Hayes - EVP, CFO & Treasurer
We--when we negotiate these contracts, obviously we are very sensitive to the needs of our managed care partners, but we're also very sensitive to the pricing dynamic, and I think our performance shows that.
Kevin Ellich - Analyst
Understood. Okay. Thanks.

Your next question comes from the line of Kemp Dolliver with Avondale Partners. Please proceed.
Kemp Dolliver - Analyst
Hi, thanks. Question relates to your progress with integrating Monogram. It just strikes me, based on the sequential improvement in earnings, that you have made substantial progress in reducing the dilution there.
David King - Chairman & CEO
Kent, it's Dave. Yes, we have made significant progress in reducing dilution there, and Monogram continues to be a very important strategic initiative for us. As a result of the--our infrastructure and logistics, we've been able to broaden the reach of their testing services, which has been positive to revenue and to reduce their expenses. The science there is terrific. The technology is terrific. We've established Monogram as a center of excellence for our virology business. They've already integrated very nicely into our clinical trials business with helping with the development of companion diagnostics. We're looking to expand their capabilities, particularly into Hepatitis C, and the revenue--the utilization uptake on HERmark now that physicians can order it without having to send their specimens to two different places has been a positive. And we've had a number of significant inquiries from clinical trials partners about the use of the Veridex assays to develop targeted oncology therapy. So, Monogram has been exactly what we thought it would be, in terms of a very important strategic acquisition for us, and we've done a good job in reducing the cost structure there.
Kemp Dolliver - Analyst
That's great. And in Q4, you had said that I dilution was $0.08. You didn't quantify Q1, but suggested you had made progress. I'm going to take another shot and ask, would the EPS effect in Q2?
Brad Hayes - EVP, CFO & Treasurer
This is Brad, we're not going to break it out, but I would characterize it as follows. The improvements that you're seeing are much greater driven by LabCorp excluding Monogram and the impact of Monogram.
Kemp Dolliver - Analyst
That's very helpful, thanks.

Your next question comes from the line of Gary Taylor with Citigroup. Please go ahead.
Gary Taylor - Analyst
Good morning, guys. A couple of quick questions. What would you say your average revenue multiple in acquisitions is for what you've acquired in the last 12 months?
David King - Chairman & CEO
Well, I don't think there's a way to quantify that, Gary, because it just varies so widely, and I'm not sure it's helpful to quantify it, either, because I think it probably--it probably has an impact in the marketplace. So, we look at--we look at multiple of revenue as one of many factors. Again, including accretion, dilution, multiple of EBITDA, pre and post-EBITDA, synergy opportunities, discounted cash flow, and the revenue multiple alone is not--is not determinative.
Gary Taylor - Analyst
Okay. Another question. When you look at your 4.2% year-over-year revenue growth, how much of acquisitions contribute to that year-over-year number?
David King - Chairman & CEO
It's relatively small, other than Monogram. And Monogram, because it was August of last year, there's certainly a--we know that Monogram is 1% positive on price all by itself, so that's a contributor. The rest of the acquisitions, the sizable acquisitions, as we mentioned in the talking points, were done in June of this year, so they're pretty small. Two weeks of Westcliff or two weeks of DCL is not going to have a major impact, given the size of our organization.
Brad Hayes - EVP, CFO & Treasurer
And, Gary, I'll just back that up with between Monogram and the two that Dave just mentioned, there's been nothing sizable to speak of, other than what I would consider to be the normal kind of small tuck-ins that are incorporated in the way we think about to the business on a go-forward basis.
Gary Taylor - Analyst
Yes, I mean we see those in the 4Q a little bit and the 1Q in there. They don't really hit the threshold to get called out, I know, but I'm just trying to think about the overall contribution. On the Indianapolis lab DCL?
David King - Chairman & CEO
Yes.
Gary Taylor - Analyst
Can you give us any sense of the size of that, or the revenues there, or -- or not?
Brad Hayes - EVP, CFO & Treasurer
I think--I believe it was the largest independent lab in the Indianapolis market, and, also, had a business in--had some business in St. Louis, and some patient service centers. So, we think of it as a nice sized acquisition, but not going to talk specifically about it's revenue or it's volumes.
Gary Taylor - Analyst
Okay. Just going to the commercial pay question. Again, that was raised yesterday, and we've talked a little bit about today. If I'm not mistaken, I saw it when you guys talked about WellPoint last year, that was renewed through mid-13, if I'm not mistaken. Is that right?
David King - Chairman & CEO
Correct.
Gary Taylor - Analyst
Can you just talk about--can you ballpark--when we look at '10, '11, and '12 for you, what percent of the managed care book has scheduled expirations?
David King - Chairman & CEO
Well --
Gary Taylor - Analyst
Even if we can use adjectives instead of numbers.
David King - Chairman & CEO
Yes. I think the problem is that we have, if I'm not mistaken, we have something on the order of 2,000 managed care plans that we deal with, and it may even be more than that. Many of these plans have contracts that are just evergreen contracts. If nothing happens, they roll over from year to year, without any--without any major changes. The major contracts that we have are--are basically extended; WellPoint, as you mentioned, out to 2013; Cigna is out in '13. We have a couple of contracts in '11 that are not--they're not small, but, again, we're already talking to the--to our managed care partners about those relationships, and we really don't have anything that's sizable in 2010 that has not been addressed. So, I think the landscape looks pretty--looks pretty clear until you get out toward the end of 2012 and into 2013.
Gary Taylor - Analyst
Okay. Thank you. Last question. The gross margin improvement, I know you touched on that a little bit earlier. Can you, in a little more detail, can you refresh to us a little bit on what's driving that year-over-year improvement? I didn't think mix would really be a big driver there, but maybe I'm wrong on that.
David King - Chairman & CEO
Yes, a couple of things have an impact on gross margin. First of all, obviously, price growth has a positive impact on gross margin because if you're doing the same volumes at a higher price with the same number of people, that helps your gross margin. So, we shouldn't overlook that. However, in my mind, the big drivers of gross margin are in the 2010 initiatives. So, the automation, which is fully completed now of our HPV preparation, and our major laboratories, the Hematology automation, which is a very substantial project, but is going to lead to substantial savings, and improved turnaround times for our customers, the improvement in patient service center work flow through appointment scheduling, the improvement in patient service center work flow through the IT improvements that basically allow the phlebotomist to accession the specimens in patient service centers, which means they don't have to be re-accessioned when they get to the laboratory. So, these are all major contributors to the gross margin improvement. And the gross margin improvement three consecutive quarters year-over-year. So, obviously it's not all from pricing, it's considerably contributed to by the efficiency initiatives that we've undertaken. And I would also comment on that in undertaking these efficiency initiatives, one of our major areas of focus has been to move our personnel out of the "back office" and into customer phasing positions. So, we've been able to increase the number of phlebotomists, increase the number of careers, increase the number of service personnel without--and still have gross margin improvement. And then the last thing I should mention is just very aggressive optimization of the supply change in terms of vendor relationships, inventory management, all of those things have been material, as well.
Gary Taylor - Analyst
And the hematology automation, where are you in that process?
David King - Chairman & CEO
All of the major core laboratories are done, so that's fully into our--into the run rate.
Gary Taylor - Analyst
Okay. Great. Thank you very much.
Operator
And your next question comes from the line of Ralph Giacobbe with Credit Suisse. Please go ahead.
Ralph Giacobbe - Analyst
Thanks. Good morning.
David King - Chairman & CEO
Good morning.
Ralph Giacobbe - Analyst
Can you maybe talk about the drugs of abuse testing a little bit? If possible, maybe quantify the positive contribution to volume and maybe the drag to pricing?
Brad Hayes - EVP, CFO & Treasurer
Ralph, it's Brad. I think Steve said it was up 15%, and it's about 5% of our volume. So, that's going to imply 0.7% or 0.8%, I think, impact on the total. And then on the price side, it's going to be a hinderance to price of just a few basis points less than that. So, not a tremendous impact on total revenue, but certainly driving some volume growth, but detracting from the price component a little bit.
Ralph Giacobbe - Analyst
Okay.
Brad Hayes - EVP, CFO & Treasurer
I want to go back to something I said earlier, that would be one of the considerations. Again, when we look at the business first quarter to second and look at a number of moving parts that we've mentioned today, even taking that component out of the analysis for both the first and second quarters, we think the business performed very much in the second quarter like it did in the first quarter.
Ralph Giacobbe - Analyst
Okay. Just to be clear, you said 5% of volume, drugs of abuse?
Brad Hayes - EVP, CFO & Treasurer
Yes, approximately.
Ralph Giacobbe - Analyst
Okay. Alright. That's fair. And then I thought you said that margins were impacted in the quarter by acquisition transition costs. How material is that? Any color there?
Brad Hayes - EVP, CFO & Treasurer
Yes, we've got obviously some acquisitions that we haven't fully integrated yet, and also the deal costs associated with those that are now, as of last year, I guess, hit the P&L, as opposed to considered in the deal cost. And I would just say that I a pretty meaningful impact in the quarter of something between 50 and 100 basis points negative impact on the margin. Now, some of that will not be erased immediately, especially as we consider back to some of Dave's comments about the Westcliff integration. That's certainly a drag in the quarter. Even though its two weeks, it is certainly impacting a little bit on the quarter, and will continue to impact going forward.
Ralph Giacobbe - Analyst
Sure. And then maybe I guess where are you with LabCorp 2010 initiatives. Obviously we're seeing it show up in the numbers. Just wondering how much more in terms of that specific program?
David King - Chairman & CEO
Well, Ralph, it's Dave. We're never going to be done with it, and I think that's probably the best thing that we've learned, is that every time we make one of these major improvements, we find other opportunities. So, in terms of quantifying have we reduced the run rate gross by the $100 million number that we said we were going to. I think with this second bad debt reduction which I attribute to the 2010 initiatives, I think we're pretty close to having accomplished what we said, but the learning has been that as we've really focused on lab operations, focused on PSC operations, focused on the supply chain, that there's still more room there.
Ralph Giacobbe - Analyst
Okay. Great. Thank you.
David King - Chairman & CEO

Your next question comein' comes from the line of Bill Quirk with Piper Jaffray.
Bill Quirk - Analyst
Thanks. Good morning. Just want to follow up on a couple of earlier questions. Dave, can you talk about how office visits trended throughout the quarter, and then did we see any changes here as we got to the end of Q2, or even taking a look at the first couple of weeks of 3Q?
David King - Chairman & CEO
I think the IMS data suggests that office visits year-over-year were down about 5% in May, and 5% in June, if I'm thinking about the numbers right. So, maybe it was April and May. But we saw physician office visits declines of about 5%, and as Brad said earlier, that's directional, it's not perfect, but the big declines, and this is not a surprise to anybody are OBGYN, primary care. And my thesis is you're seeing a lot of people who are not getting their annual physical. They're not going in for their annual checkups. They're deferring or postponing nonacute visits. And I--I'm not going to talk about--I don't know what the answer is for the first two weeks of 3Q. I wouldn't tell you if I did know, because we don't talk about our quarters when we're in them, but I don't see anything that's changing material. I don't see anything that's changed significantly in the office visit environment since the beginning of this year, and even the 4Q of last year.
Bill Quirk - Analyst
And so just taking that and taking a look forward here, Dave, presumably, then, as we think about the guidance for the back half of the year, you're not assuming an meaningful improvement that environment?
David King - Chairman & CEO
Correct.
Bill Quirk - Analyst
Okay, very good. And the last question for me, it's a housekeeping one, top test for the quarter, I don't think you mentioned it, if you did I apologize, but if you would give us a little color there. Thank you.
David King - Chairman & CEO
I don't think we usually do mention it. So, I don't think we have broken with any precedent by not mentioning it, but, the--I mean, it shouldn't be any surprise, and I'm not going to tell you what any particular top test is, but we continue to see strong growth in vitamin D. We continue to see strong growth in HPV. And some of the esoteric testing, the anatomic pathology, as briefly mentioned, was done a little bit, although the trend was better. We're actually seeing positive trends in some of the core to testing like hemoglobin A1c, lipid testing, thyroid testing. So, there's a good mix of areas would where we're seeing volumes improve on a test by test basis.

Your next question comes from the line of Darren Lehrich of Deutsche Bank. Please proceed.
Darren Lehrich - Analyst
Thanks. Just a couple here left. I guess I want to just go back to Westcliff. What is the timing of the FTC review? And can you just update us? It just seems like $100 million revenue operation in a state as big as California seems like an odd thing to be looking at. So, maybe can you just sort of update us on why that review is even going on?
David King - Chairman & CEO
Well, answer to the first question, we don't know the timing. The FTC has said they are reviewing the transaction. We are providing them the information they want to look at. Our hope is they will complete the review expeditiously and clear the transaction. As a reminder, the purchase price was below the Hart-Scott-Rodino threshold. So, this was not a transaction we even had to file for clearance on. As to why the FTC is even looking at it, I have no idea.
Darren Lehrich - Analyst
And going back to Brad's comments about Westcliff and the impact that it's having, what--if there's any discreet way or sort of way to frame the margin impact on a quarterly basis while you wait for the FTC, and if you could just help us think about how that is sort of built into your thought process in the second half.
David King - Chairman & CEO
Well, maybe just explain the structure of what--of what it is. So, Westcliff is being run as a separate business. There is a manager of the business who runs the business, and then there is a monitor who oversees the business to make sure that any actions that are taken do not compromise the standalone nature of the former Westcliff business. So, that's--those are where decisions are made. The only thing I think we can say from a margin perspective, Darren, is right now the expenses are higher than the revenues, and so that has a negative effect on margins.
Darren Lehrich - Analyst
Okay. And you've assumed that for the balance of the year? Is that what's in the guidance?
David King - Chairman & CEO
That's right.
Darren Lehrich - Analyst
Okay. And then my last thing was really just going back to bad debt, and want to just clarify something and then maybe dive a little bit more deeply into this. Are you saying that there's now a 50 basis point improvement versus what you originally had? And can you just clarify those comments, and what is, I guess, the bad debt outlook at this point? And then Brad, obviously a good result. David mentioned a lot of the hard work that goes into that kind of result, but is this mixed ribbon in any way, or is this just really more about process?
David King - Chairman & CEO
First to review the numbers, we reduced 25 basis points in the first quarter, and then an additional 25 in the second. So, year-over-year, you're right, it's 50, but sequentially it's 25. And I would have to say, I think we said this on our first quarter call, that we expected the 25 in the first quarter, maybe the 25 in the second is because we're doing better than we would have thought. I would say that, no, mix is not at all a driver of our improvements. The driver of our improvements are the initiatives that we first laid out back in the middle of 2008, that haven't changed in terms of what they are, but have changed in terms of how we're executing against them. We continue to make progress in all of those initiatives. I won't say that we haven't added any, but those foundational initiatives are still alive and well. And, as I look at what's in front of us, I think, again, we still have opportunity to do better. You know, there is process improvement in the area, there is performance by individuals' improvement in the area, and it's completely our results are a result of all of that heavy lifting as opposed to anything that's fundamentally going on. We look at credit card default rates and consumer information, and I don't think the environment has gotten any easier. It may have plateaued, so it's not continuing to get worse. But I just see that as sort of the fact that maybe one headwind we were fighting for awhile has subsided a little bit, but still, it plateaued at very high levels compared to history. It's completely the initiatives in the heavy lifting.
Darren Lehrich - Analyst
Thanks, that's great. Okay. Thank you.

Your next question comes from the line of Anthony Vendetti with Maxim Group. Please proceed.
Anthony Vendetti - Analyst
Thanks. Most of my questions have been answered, but just a quick follow-up on two things. On the volume that was down, and you highlighted the office visits that were down. Do you believe that--that is a bottom and it's stabilized, or is it too early to be able to tell whether, or not this would continue and would you attribute that to unemployment, or what do you think is the cause for that?
David King - Chairman & CEO
I think it's too early to tell. I think it's--I don't think we're seeing big month over month declines. It has gotten worse from the beginning of the year, when you look at the year-over-year perspective, but, in my mind, there are a couple of things going on, and they tie together. One is we're not seeing creation--job creation in the private sector. So, unemployment remains high, and most job creation is--is not coming from private sector jobs. What that translates into is that managed care enrollment, commercial managed care enrollment is down. And with commercial managed care enrollment down, that translates into people are not insured, and as a consequence, they're choosing--it isn't that they're going to the doctor as uninsured patients, it's they're staying home. And if you just look at our percentage of uninsured, one would have thought, in the abstract, that with the number of uninsured in the US going up, and the number of people losing their jobs, you would have thought our uninsured patient number would have gone up. It went down, and I again, I think it's because people without insurance are staying home, and that's why doctor visits are going down. And even people with insurance who feel that they can skip that annual checkup or wellness checkup, are staying home as well. So, in my mind the answer is, I don't know who whether we're at the bottom, and I don't know if we're going to see a lot of change until we start to see job creation in the private sector, which leads to managed care enrollment.
Anthony Vendetti - Analyst
And then the follow up was on the renewals. And I know you touched on this. Most of the major contracts, well, at least WellPoint, Cigna out to 2013, nothing really anything sizeable this year, but you said there were some sizable ones in 2011. Did you want to name the ones in there? And if not, if you could just say what percent of your book of business those sizable contracts that are up for renewal in 2011 would account for?
David King - Chairman & CEO
They're not--I don't want to name them, and they're not big enough in and of themselves to be materially impactful to our total book of business.

And your final question today comes from the line of Steven Valiquette with UBS. Please proceed.
Steven Valiquette - Analyst
Hi, thanks. Obviously, there's been a lot of questions here on the managed care prices, but if we--I guess if we focus just on your managed care fee for service line and the revenue per accession growth data you provide, which obviously was 3% growth in this past quarter we, and has been in that 3% to 4% range, is there any reason to think that the growth numbers reported in that line going forward are going to be really any different than the trends we've seen in the last 12 to 18 months?
David King - Chairman & CEO
No reason that I can think of.
Steven Valiquette - Analyst
Okay. Alright. That's helpful. One other quick one. I may have missed this, but as far as the price tag on Westcliff, the $57 million to $58 million range? Is that essentially the ballpark of where it was, or is there some debt assumption on top of that? Just trying to get a read on the full price tag on that.
David King - Chairman & CEO
