Statements made throughout this presentation are based on current estimates of future events and speak only as of today. The Company does not undertake a duty to update or correct these forward-looking statements.
Our slide presentation and discussion on this call will include certain non-GAAP financial measures. For such measures, reconciliations to the most directly comparable GAAP measure is available at the end of this slide presentation or at the end of the related press release, both of which are available on our website as part of the Form 8-K filed last night with the SEC.
Before I turn it over to Jay, I would like to remind you that we will adhere to the one question and one follow-up question rule to allow everyone to submit a question. If you have additional questions please feel free to put yourself back in the queue. And with that I will turn the call over to Jay.
Jay Grinney - President & CEO
Thank you, Mary Ann. Good morning, everyone. We appreciate you joining us this morning for the call.
The fourth quarter was a strong finish to another solid year for HealthSouth. Total discharges grew 2.1% while same-store discharges were up 1.7%. These were healthy results given the 5.9% growth achieved in the fourth quarter of 2010. Our growth compares favorably to the rest of the industry. As shown on page 24 of our supplemental slides, discharges from non-HealthSouth hospitals reporting through the UDS reporting system were down 0.5% in the quarter. This suggests our superior outcomes, focus on high-quality patient care and our TeamWorks sales and marketing initiative continue to drive market share to our hospitals.
Our volume growth, coupled with the continued shift of our patient mix towards more Medicare patients, the continued shift of our program mix towards more patients with neurological conditions, a modest Medicare pricing update, inline managed-care pricing increases and the sustained benefits from our care management initiative generated $518.1 million of net operating revenues, an increase of 5.5% compared to last year's fourth quarter.
As a reminder, our care management initiative was designed to standardize best practices at all our hospitals in the areas of pre-admission screening, post-admission care coordination and discharge planning. These best practices have resulted in fewer acute-care transfers which, in turn, has resulted in fewer partial Medicare payments. We were especially pleased that our efficient operating platform allowed us to leverage this topline growth to achieve $122.9 million of adjusted EBITDA and generate $99.2 million of adjusted free cash flow in the quarter.
We chose to invest this excess cash in strengthening our balance sheet by paying down approximately $73 million of debt and purchasing the assets of one of our joint ventured hospitals whose lease had expired in Morgantown, West Virginia. This debt repayment brought our year-end leverage ratio to 2.7 times, well within our three times target.
Finally, our earnings per share for the quarter was $0.50 per share. Unfortunately, this number may create some headline noise because it reflects an effective tax rate of 22%. While most analysts' models use a 40% tax rate, a 40% rate would have yielded $0.39 per share.
As a reminder, HealthSouth does not pay federal taxes because of our substantial NOLs. Our cash taxes for the quarter were $2.3 million.
Doug will now provide a more thorough review of the quarter and the full-year results.
Doug Coltharp - EVP & CFO
Thank you, Jay, and good morning, everyone. I'll focus my comments on the fourth quarter but I will also highlight certain results for the full year and elaborate on a number of the assumptions underlying our 2012 guidance.
As Jay mentioned, Q4 represented a strong finish to a strong 2011. Revenue increased 5.5% in Q4, driven by inpatient revenue growth of 6.1%. Inpatient revenue benefited from both volume and pricing increases.
Beginning with volume, our discharges increased 2.1% in Q4 2011 over Q4 2010 inclusive of 1.7% same-store growth. As a reminder, we were up against a tough comparison, having generated discharge growth of 5.9% in Q4 2010. For the full-year 2011, we grew discharges by 5.2%, 3.3% same-store, demonstrating our ability to continue to gain market share.
Moving to pricing, our revenue from discharge for Q4 increased by 4% over Q4 2010. As anticipated, we realized a 1.6% increase in our Medicare reimbursement rates. Our Q4 revenue per discharge was also aided by a shift in our payer mix -- 72.8% Medicare for Q4 2011 versus 71.6% in Q4 2010 -- and a shift in our patient mix. Neurological cases comprised 17.5% of our mix in Q4 2011 versus 15.4% in Q4 2010. Stroke was unchanged at 16.4% and replacement of lower extremity joints declined from 9.8% in Q4 2010 to 8.6% in Q4 2011.
Our outpatient and other revenue declined 1.6% in Q4 2011, primarily as a result of the closure of six satellite clinics during the course of 2011. At the end of 2011, we continued to operate 26 outpatient satellites.
Please be reminded that the vast majority of our outpatient revenue comes from our hospitals and not from the satellite clinics.
Our continued focus on expense control combined with the 5.5% revenue increase resulted in 110 basis points of incremental operating leverage in Q4 2011 versus the prior year quarter. SWB as a percentage of net operating revenue rose by 10 basis points in Q4 2011 to 48.5% as enhanced labor productivity, EPOB, improved to 3.46 in Q4 2011 versus 3.50 in Q4 2010, was offset by the ramp-up costs at two new hospitals, Cyprus and Drake; also by a modestly higher group health benefit and workers' compensation expenses and our decision to provide all of our employees with an extra half day of paid time off as a form of holiday bonus.
Please recall that Q4 2010 included a $3.3 million favorable adjustment related to workers' compensation accruals. Although Q4 2011 workers' compensation was higher than the prior year period, it also included a beneficial adjustment. At this time, we are expecting workers' compensation expenses to normalize in 2012, resulting in year-over-year expense increase of approximately $5 million.
Hospital-related expenses for Q4 2011 were 21.6% of net operating revenues, a decline of 120 basis points from Q4 2010. This category of expenses was favorably impacted in Q4 2011 by an adjustment to our general and professional liability insurance accruals and a nonrecurring franchise tax refund of $2.4 million which we do not expect to repeat in 2012. Partially offsetting this benefit was an increase in bad debt expense in Q4 2011 compared to Q4 2010.
As we had anticipated, bad debt expense as a percentage of net operating revenues increased to 1.2% in Q4 2011 as compared to 0.3% in Q4 2010, an increase of $4.5 million. This was based on both an increase in medical necessity claims reviews and a decline in prior period recoveries, attributable primarily to a reduction in the pool of outstanding claims.
Looking forward to 2012, we expect bad debt expense to approximate 1.3% of net operating revenues versus 1% for 2011, based on the aforementioned factors as well as an expected lengthening of the Medicare denial adjudication process related to a mounting administrative backlog. This anticipated increase in bad debt expense would create a headwind of approximately $6 million to adjusted EBITDA and EPS growth in 2012.
Remaining on the 2012 operating expense outlook for a moment, please recall that we are now in the midst of a systemwide rollout of a new clinical information system. This rollout will occur over an approximate five-year timeframe and is expected to result in an incremental $4 million of operating expenses in 2012. We anticipate approximately 70% of the total cost of the CIS rollout will be capitalized and the balance expensed.
Turning back to 2011, Q4 adjusted EBITDA of $122.9 million represented 9.6% growth over the same period in 2010. For fiscal year 2011, adjusted EBITDA of $466.2 million represented an increase of 13.8% over 2010. While we are obviously very pleased with the strength of these operating results, most notably with the discharge volume growth, we recognize the beneficial impact of the expense items we just discussed and the corresponding hurdle they create for adjusted EBITDA growth in 2012.
We continue to believe that our business model should generate a 5% to 8% adjusted EBITDA CAGR over the three-year period covering 2012 through 2014.
Interest expense for Q4 2011 of $23.1 million compared favorably to $34.2 million in Q4 2010 and was reflective of both our declining leverage and the improvements we have made to our debt capital structure. As Jay mentioned previously, we reduced debt by an incremental $73 million in Q4 2011, bringing the total reduction for 2011 to $257 million and resulting in a year-end leverage ratio of 2.7 times. The benefits of our reduced leverage and improved capital structure will be increasingly evident in 2012 as we anticipate full-year interest expense of approximately $96 million versus $119.4 million for 2011.
The year-over-year earnings-per-share comparison continues to be primarily impacted by fluctuations in our effective tax rate. Diluted earnings per share for Q4 2011 were $0.50 per share compared to $7.15 per share for Q4 2010. Earnings per share in Q4 2010 included a large income tax benefit, primarily attributable to the release of a substantial portion of a valuation allowance.
On a full-year basis, earnings per share for 2011 were $1.42 per share as compared to $8.20 per share in 2010. Again, EPS for 2010 included a large income tax benefit primarily related to a valuation allowance release.
You will find a detailed comparison of our Q4 and 2011 EPS to the prior period on slide 10 of the supplemental slides.
Our federal NOL balance at December 31, 2011 was approximately $1.3 billion and the remaining valuation allowance at the end of the year was approximately $50 million. Cash income taxes for 2011 were $9.1 million and are anticipated to be $7 million to $10 million in 2012.
Let's move now to free cash flow and I'd direct your attention to slide 16 of our supplemental slides. As we discussed beginning in our Q3 earnings call, we anticipated strong adjusted free cash flow growth in Q4 aided in part by the shifting of approximately $16 million in interest payments into Q3. During Q4 2011, we generated adjusted free cash flow of $99.2 million resulting in full-year 2011 adjusted free cash flow of $243.3 million, an increase of 34.1% over 2010. This was driven by our higher adjusted EBITDA and benefited from lower cash interest payments and swap-related payments.
Our adjusted free cash for 2011 was net of $50.8 million in maintenance capital expenditures. As we have stated on several previous occasions, we expect 2012 maintenance CapEx to increase to $75 million to $85 million based primarily on the rollout of our clinical information system and two substantial hospital renovation projects.
We expect to continue to generate a significant level of adjusted free cash flow in 2012 but the year-over-year growth is anticipated to be slower, in large part owing to the 34% increase in 2011. Although we will reap further benefits from reduced cash interest expense and the cessation of swap-related payments, these items are likely to be offset by the aforementioned increase in maintenance CapEx and an anticipated $30 million to $40 million increase in working capital.
Let me elaborate for a moment on the anticipated increase in working capital. There are two primary components to this.
First, we anticipate an increase in our accounts receivable balance, stemming from both a higher volume of medical necessity claims reviews -- an additional CMG has been added for 2012 -- and the previously mentioned lengthening of the adjudication process related to the mounting administrative backlog.
The second component is an expected increase in payroll liabilities primarily related to one of the tranches of our long-term incentive plan or LTIP. The shares awarded under the 2009 LTIP were earned at a high level based on the strong performance of the Company in 2009 and 2010. Those earned shares will fully vest in 2012.
As restricted shares vest, we offer our employees the option to have shares withheld to cover the related payroll tax. When employees choose this option, which most do, the Company retains the shares but must remit cash to the IRS to cover the payroll taxes. We expect such cash payments to approximate $10 million in 2012. This payment will have no effect on our 2012 adjusted EBITDA or earnings-per-share, but it does flow through working capital as a reduction in an accrued liability and, as a result, impacts adjusted free cash flow.
Similar to my comments on adjusted EBITDA, we continue to believe that our business model should generate an adjusted free cash flow CAGR of 12% to 17% over the three-year period extending from 2012 to 2014, but annual results may be outside of that range.
As we had previously disclosed, there was no activity under our $125 million share repurchase authorization during Q4 2011.
I'll wrap things up with total CapEx, which was approximately $114 million for 2011. In addition to the previously discussed $50.8 million in maintenance CapEx, this included approximately $63 million in growth CapEx. Our growth CapEx in 2011 included the following. Approximately $12.5 million of capacity expansions; two de novos -- Cyprus, which opened in Q4 2011, and Ocala, which will open in 2012; our acquisition of Drake; and the purchase of two hospital properties, Morgantown and Lakeview, previously operated under long-term leases. This is consistent with our belief that control of our real estate adds to our competitive advantage.
And with that, I will turn it back over to Jay.
Jay Grinney - President & CEO
Great. Thanks, Doug. Before we take questions I'd like to discuss in a little more detail our initial 2012 guidance and highlight some underlying assumptions and considerations.
This information is summarized on pages 13 and 14 of our supplemental slides. Discharge growth remains the most important performance metric. Our 2012 guidance is based on the assumption discharges will increase between 2.5% to 3.5% compared to 2011. Same-store discharge growth is expected to be approximately 2% to 3% with the balance coming from our two new hospitals, Cyprus and Drake. Our hospital in Ocala is not expected to open until December so its contributions to discharges and earnings will be seen in 2013.
We also have several other projects in our development pipeline that will come online in 2013.
From a de novo perspective, we have three new hospitals that will begin construction in 2012 -- a new 34-bed hospital in Martin County, Florida, with our joint venture partner, Martin Health System; a new 40-bed hospital in Littleton, Colorado; and a new 40-bed hospital in southwest Phoenix. These hospitals are expected to be opened in 2013, but the exact timing will be dependent on securing appropriate permitting in a timely fashion this year.
We're also defending appeals against two of our certificates of need -- one in Williamson County, Tennessee, the other in Middletown, Delaware. In both instances we had land under contract and have begun the design phase to enable us to move quickly once we have successfully litigated these appeals.
Finally, we are completing due diligence and market assessments of two additional de novos that we expect to announce in the next 90 days. We anticipate these projects will be under construction by year end. In addition to these de novos, we are exploring several potential partnerships and acquisitions that, if consummated, also will contribute to earnings in 2013.
Getting back to our 2012 guidance, we are factoring in a 2% to 2.5% pricing increase on a revenue per discharge basis. This incorporates the modest Medicare update we received October 1 and managed-care increases that are a little north of 3%. The closure of several of our unprofitable satellite outpatient clinics and a 4% reduction in our home health Medicare pricing will result in total revenue growth of approximately 4% to 5%.
There also are two factors that will create slight headwinds for us next year. First, as we previously disclosed, we plan to install our new clinical information system in 12 of our hospitals in 2012. This will add incremental operating costs of approximately $4 million.
As a reminder, rehabilitation hospitals are not eligible to receive high-tech payments, so there will be no offsetting revenues to apply against these expenses.
Second, we anticipate a continuation of widespread reviews of an expanded number of diagnosis codes by certain fiscal intermediaries. As Doug said, we expect this will cause bad debts to increase by approximately $6 million in 2012 compared to 2011 and will bring bad debt as a percent of net operating revenues to approximately 1.3%.
Taking these factors into consideration, our initial 2012 adjusted EBITDA guidance is between $475 million and $485 million. In performing year-over-year comparisons, it should be noted that certain nonrecurring items benefited adjusted EBITDA in 2011. These were a $1.5 million net benefit resulting from state provider taxes, $2.4 million from a nonrecurring franchise tax recovery, and a $3.8 million reduction in self-insured worker compensation costs, primarily due to revised actuarial adjustments from better-than-expected claims experience in prior years.
From an earnings-per-share standpoint, the most important distinction between reported 2011 EPS and 2012 guidance is the difference in the effective tax rates. The effective tax rate in 2011 was approximately 19%. In 2012, we are assuming a 40% effective tax rate.
It should be noted our 2012 cash taxes are expected to be between $7 million and $10 million. With this in mind, our initial 2012 EPS guidance is between $1.32 and $1.39 per basic share.
As we begin a new year, I think it's important to consider what we've been able to accomplish since turning around the Company at the end of 2007. In 2008, our first full year as a focused post-acute company, we generated $9.3 million in adjusted free cash flow. Four years later, in 2011, we generated $243.3 million in adjusted free cash flow.
We believe our strong cash flow generating capacity is the real success story for HealthSouth. The strategies we've deployed have allowed us to achieve these results while positioning the Company to enter 2012 with a strong balance sheet and a business model that has a proven track record of generating significant operating cash.
As outlined on pages 16 through 19 of the supplemental slides, we are fortunate to have multiple opportunities for investing this cash flow for the long-term benefit of our shareholders.
First, as we have discussed earlier, we will install an electronic clinical information system in all of our hospitals despite not being eligible for high-tech payments. This investment is crucial to being a good partner with our referring acute-care hospitals and positions HealthSouth to participate in the evolving ACO and bundling environment.
Second, we have the ability to invest in our existing portfolio through two major hospital renovations and several major refresh programs in 2012, all of which will facilitate future growth in these markets and at these facilities.
Third, we will continue to invest in bed additions at hospitals with exceptional demographic and market share gain profiles, ensuring we keep up with the demand for our services in these markets.
Fourth, we will add new hospitals to our portfolio by building de novos, acquiring competitors or partnering with acute-care systems.
And finally, depending on relative risk return dynamics and other exogenous factors, we will consider opportunistic share repurchase dividends and/or debt repayment.
We are very proud of what we've accomplished in 2011 and look forward to the year ahead. The fact that we have delevered our balance sheet, continue to generate strong cash flow, and have a proven track record of achieving strong financial and operational results positions us to be able to continue to grow, to continue to adapt to external events and to continue to create value for our shareholders in 2012 and beyond.
With that, Paula, we'll open up the lines for Q&A.

Ann Hynes - Analyst
So my two questions -- one, I want to focus on cash flow. Obviously you're generating a lot of it and you have been clear about your cash flow deployment opportunities, but I really want to focus on short-term cash deployment over the next 12 to 18 months since the Presidential election does create some uncertainty in Washington.
So besides the bed adds and the de novo projects you've already outlined, could you actually rank in priority the short-term cash deployment over the next 12 to 18 months -- acquisitions, debt repayment, share repo, or a dividend?
And my second question is on the clinical information rollout. I assume going high-tech will create a lot of efficiencies at the hospitals over time. Do you actually have a estimate for hospital potential savings once everything is rolled out? Thanks.
Jay Grinney - President & CEO
Okay, I'm going to take the second question first. We have not included any savings in the presentation that we delivered to the Board on the clinical information system. And quite frankly, the reason is, when we went out and we looked at other healthcare systems that installed these similar electronic clinical information systems, we really didn't see a lot of demonstrated cost savings. And frankly we were not going to simply take the projected savings that the various vendors were throwing around, because it's easy to put a number out there; it's another thing to actually achieve those savings.
We see this as an investment in our business and an investment in our future. I think everybody would agree that today it's not a matter of should you put in an electronic clinical information system; it's rather when are you going to put in an electronic clinical information system. When you think about establishing tighter connections with our referring hospitals, when you think about the potential for moving into some kind of ACO environment or potentially going into bundled payments, the transfer of clinical information electronically is absolutely the way the industry is going. And we don't want to be left behind.
We don't think we are investing too late. We think the timing is perfect. The only regret we have is that we are not eligible for the high-tech payments.
The good news on that for all of the analysts on the call is you don't have to try to figure out if we've got real earnings or high-tech facilitated earnings. Our numbers are going to be a lot easier to figure out than those who get the high-tech payments.
In terms of the cash flow and prioritization, our first, second, and third priority is to push dollars back into the business and to grow this platform of inpatient rehabilitation hospitals. And frankly, over the next 24 months, we see that that is the highest and best use of our cash and we're going to be trying to deploy as much as we can in a very disciplined way and very careful analysis to put dollars into that growth. Because frankly, in 2012, with the doc fix in place, we don't see any additional regulatory or Medicare payment headwinds.
You know, whether or not the lame duck session does anything that's going to be dramatic I think is anybody's guess. We're handicapping that to be probably a low probability, frankly. So, 2013 then becomes an issue of what's the impact of sequestration going to be and is there going to be an additional kick the can down the road or major doc fix.
So right now we are saying let's take the cash, let's go ahead and invest in our business. You heard that we are -- if you add up everything that I talked about in terms of de novos, we're actually above that four per year clip that we had talked about previously. We had suspended the accelerated de novo project because of the regulatory uncertainty. That is now full throttle again. We're seeing some interesting opportunities in the acquisition front. Again, just IRFs and potential partnerships with acute-care systems.
So with all of that in mind we really think that that's the best place to put our cash in the short term. We think that if there's going to be any long-term structural or traditional massive cuts to providers we won't be seeing that until probably 2014.

Adam Feinstein, Barclays Capital.
Adam Feinstein - Analyst
Jay, just had to -- as you were reflecting back and having covered the Company the whole time, it really has been an outstanding job, so just wanted to want to say that -- you guys have done a phenomenal job and just seeing the leverage down where it is, it's great to see.
Jay Grinney - President & CEO
Thank you. It's very comforting to have it. I'd much rather have it at 2.7% than 5.7% or even 4.7%.
Adam Feinstein - Analyst
Absolutely. So maybe, Jay, if you could talk a little bit about the competitive landscape. I mean, clearly you guys are showing strong volume growth. And so just looking at some of the industry data, obviously, you guys are taking market share. But I guess talk a little bit about the competitive landscape in terms of other freestanding rehab hospitals, hospital base units and even the competition from nursing homes with some of the reimbursement cuts they are dealing with and changes they're going through.
So, just curious to get your thoughts in terms of the overall competitive landscape and how you see that playing out over the next 12 to 24 months.
Jay Grinney - President & CEO
Yes, I think that what we have said for the last maybe year, 1.5 years is emerging as the operating environment that we're in and that is from a rehabilitation competitive landscape, the hospital units are increasingly under pressure because their acute-care sponsor, the acute-care hospital that they are in, is -- they are under pressure from a reimbursement standpoint. They are getting less dollars from managed care. They're having to deal with the ObamaCare pay for. They are looking at sequestration next year. There is the various cuts that occurred as a result of the doc fix. There could be more. And so what we're seeing is the acute-care hospitals and systems that are more forward-thinking -- they're not just looking at today, they're looking down the road -- are asking themselves can we really afford to be all things to everybody the way we have in the past. And increasingly the answer is no.
So what we're seeing, and it's slowly emerging, is an interest on some of the more progressive healthcare systems to say okay, in the past we had to own and operate everything. Tomorrow, we're not going to be able to afford to do that, especially if there are continued CapEx needs in our core acute-care business.
Okay, so with that in mind, what are we going to do? Either we monetize the non-core assets or we consider partnering with someone who can come in, we can offload some of the risk on the post-acute space and monetize a portion of those services but still have control. And that is probably the biggest difference, Adam, between February of 2012 and February of 2011. In 2011 we said that's what we think was going to happen. In 2012, that's what we are seeing beginning to happen.
In terms of the SNF, there's really not a big difference there. The fact that they are not getting as much for the therapy services probably is going to put a little more pressure on them to try to make it up with more patients. But they are under some pressure and so they have a very difficult situation to deal with while trying to meet this demand at the same time you see companies out there, nursing home companies, talking about having to take out costs.
Well, the costs are going to be taken out primarily through labor costs. And with the labor cost reductions, ultimately you're going to put some pressure on being able to maintain any semblance of quality. So we don't see the SNF environment changing that dramatically. However, we do think that it will be more challenging for them to maintain any semblance of quality in those higher acuity patients that we treat, and that could conceivably be admitted to a nursing home if there is no ERFs available or if the admitting physician may have a medical directorship arrangement or some other factor. Does that help?
Adam Feinstein - Analyst
That's very helpful. And maybe just one quick follow-up question, either for you or Doug here. Just the opportunity to purchase lease properties. You guys call that out as something that you would be interested in.
You know, Doug, you made some reference earlier to two recent properties. But just as you think about that, how big of an opportunity is that over the next several years? I guess can you just frame that for us?
Doug Coltharp - EVP & CFO
Certainly. Not as big as we would like, unfortunately. There is one lease that is up for renewal in 2012 that has a purchase option. So, we'll take a look at that and see if it makes sense to either extend the lease or exercise that option. And then there are about half a dozen over the next several years.
Adam Feinstein - Analyst
Okay, great. Thank you very much.
Operator
Colleen Lang, Lazard Capital Markets.
Colleen Lang - Analyst
Just on the pricing front do you expect the mix shift towards more Medicare to continue into 2012? And if so, is that included in your guidance along with the dynamic of you treating more neuro and less lower extremity fractures that you've done especially in the second half of 2011?
Jay Grinney - President & CEO
You know, we haven't forecasted in a significant shift away from what we saw in 2011. So, it's hard to know what that's going to really look like in terms of the movement out of managed Medicare and into traditional Medicare. We'll probably start to see that in the first and second quarter. And no, we have not anticipated any major shift in our program mix.
Colleen Lang - Analyst
Okay, great, and then on your comment about the evolving healthcare landscape, are the hospitals and physicians in your market ramping up discussions about forming ACOs or ACO-like arrangements or do you think that's still further down the line?
Jay Grinney - President & CEO
It's very mixed, with the preponderance of our referral hospitals declining to participate at this time. We do have a partner in one of our markets that is looking to develop an ACO and we are in those discussions with them to participate on the rehab side. Obviously -- they are a 50-50 partner, so obviously they are very incentivized and excited about us being at the table.
We're just not seeing a lot of it. And I just -- I keep going back to what we've said before, which is, I think this is really going to be an evolution. It's not going to be a revolution. And as such, it's going to take a while for this to really be proven to have long-term benefit and therefore to be accepted within the industry.
I mean, when you think about it, it's just -- it's a little bit stronger version of capitation which we saw back in the 1980s and 1990s. Capitation is not around as the predominant model today for a lot of different reasons that we all know about.
So the question is, has the landscape changed, the dynamics changed, have patients' willingness to deal with some of the downside of being in a closed network and having the physicians paid on a capitated basis and paid -- and providers paid on a fixed basis? That just -- it is going to take a while to play this out.
The good news is, we do have -- a third of our hospitals are in partnerships today. So to the extent that those markets start to move, as we saw in this one example, into either an ACO on a pioneer basis or some other basis, we'll be able to be there at the table. We'll be able to participate. We are confident we can bring value to the ACO, but we'll also be able to learn from that as we see this thing evolve over the next five to seven to 10 years.

So Doug, you obviously commented about the use of working capital. And I guess I just wanted to touch on the medical necessity reviews here, creating a lot of headaches for you guys, administrative burden and, obviously, delay. I guess, just a couple things to ask.
First, could you comment on what kind of denials you are seeing at this point, and as they sort of step up the activity levels and broaden the scope of that, maybe just characterize how that's impacting your ability to ultimately get paid.
And secondly, as I understand it, I think you have an opportunity at some point to elect other MACs as those MACs are awarded new contracts. So what is the plan there and how might that play out?
Jay Grinney - President & CEO
Let me try to answer that, and then I'm going to ask Doug to fill in in terms of the collection activity. On the MACs, when the MAC structure was first unveiled, multi-systems like ours had to make a decision. Either we put all of our eggs in the MAC that received the contract for the geographic area where the corporate office was located or we went with a decentralized and every hospital then went with the MAC that won the contract for that geographic market.
We chose the latter. Unfortunately, the fiscal intermediary that we have most of our relationships with today is a very difficult FI to deal with. And we've tried to improve relationships. I think we're making some progress, but, you know, it's a tough environment in that particular case.
So, we have made the decision. We're going with the decentralized FI or MAC configuration. But as you know, those things are really -- they are way off schedule, and so it's going to take a while for this to play out. But that was the decision we made a couple years ago and the --. What we find today, what we see today in terms of the issues with Cahaba, all that does is reinforce that we made the right decision when we went down that direction.
In terms of the -- just a comment I'll make on the denials. What happened was they added an additional diagnosis code. So, they've expanded the reviews. The biggest issue is that there is a backlog of these claims being adjudicated because there is a shortage of administrative law judges. So, what we're seeing is in part a slight increase because now we've got more -- we've got one more code that they are going to go and quibble over. And so some of those, we win because they ask for some additional documentation. And they say, okay, that's good. We are going to pay you.
Then there are others that they say, well, okay, you gave us some more information but we still don't think it was medically necessary. And we say, in some cases, all right, maybe the documentation isn't as precise. Fine. But the vast majority of them we say, you know, these patients really did need it. The documentation is there. And we're going to fight you on this.
So that's the adjudication process that takes literally 15 plus months to resolve. The problem is, as those things are going into the pipeline, the pipeline isn't moving because we've got fewer administrative law judges out there adjudicating these claims. That's the bad news.
The good news is we heard this week from our internal counsel that CMS is trying to address this backlog. So they are trying to assign the different administrative law judges. They're trying to streamline the process. They're trying to make it more efficient and resolution faster. They're also trying to standardize some of the criteria used.
The biggest issue right now is, if we go up against three fiscal intermediaries, you're going to be dealing with three different criteria; and then if we go to three different law judges, we've got three more different criteria. So CMS, to its credit, is really trying to get their arms around this. They realize they've got a problem and they're working on it. From a cash flow standpoint I'm going to ask Doug to respond.
Doug Coltharp - EVP & CFO
Just to put a little bit of context around this, recognize that although this is certainly a nuisance, the total number of our discharges that typically wind up in the denial process, even with this heightened activity, is somewhere between 1% and 1.5%. What causes us to have to discuss this is the year-over-year fluctuation from the activity because that then has an impact on our working capital.
If you think about our total bad debt, which even next year with this increase, we are suggesting will be at 1.3% of net operating revenues, because of our payer mix and because of where we are in the healthcare lifecycle, this is really the primary source of our bad debt. And even when discharges are subjected to the denial process we ultimately have a relatively high degree of recovery on those.
So we are pointing this out simply because the on-again off-again nature that has occurred over the last several years causes these rather substantial fluctuations in our AR balance. You know, as it smooths out over time, it's just not that big an issue. It's a nuisance. Frankly it's not something that consumes a lot of assets or detracts from our ability to focus on the core operating business.
Darren Lehrich - Analyst
That's really helpful context. And if I could just follow up with a clarification on the response you gave to Ann's just about capital. I guess you've sort of hinted here now that you've got I guess eight de novo projects in the hopper. A couple you still haven't announced and a few under appeal. But, how would you describe your M&A pipeline?
I just want to get an updated thought, Jay, briefly on what the acquisition pipeline looks like. Because it seems like that might be the swing factor relative to guidance. There is no M&A in the guidance, I believe.
Jay Grinney - President & CEO
Yes. You are right. There is no M&A beyond what we have in 2012 is Drake and Cyprus; and, obviously, we haven't provided anything for 2013. You know, the M&A pipeline is certainly more robust this year than it was last year. Some of those, frankly, are systems looking to monetize and get out. But there is a good number looking, at least initially, at the possibility of entering into some kind of partnership arrangement.
And again, the fact that we have one third of our hospitals that are already in some kind of partnership arrangement, I think, makes us at least attractive and we should be at the table with these systems. The fact that we can demonstrate that we are the nation's leading provider of inpatient rehabilitation, that helps us out as well.
So we're pretty excited about the opportunities to expand our presence and provide our higher level of care to new markets and to new communities. And so, it's certainly a better environment today than it was last year. And that's why when I answered Ann's question I did it the way I did, is -- you know, if you go to slide 18 on the supplemental, you can see what we've got in terms of debt expansion. And that's a pretty good number -- $20 million, $25 million, to add another 80 to 100 beds in those high-growth markets. And you think about it, that is another two hospitals -- the equivalent of two hospitals. And then, just looking at the $50 million to $70 million that we've got in there, complete Ocala and start four others, obviously, if some of the things that we talked about earlier come to fruition, that number is going to go up a little bit. So we've got a lot of opportunities to invest in the core business and we still think that that's what makes sense for the long-term.

John Ransom, Raymond James.
John Ransom - Analyst
Jay, you did a press conference -- that's a bad word -- a conference call back in the fall, giving an idea of what Obama's proposals would do to your P&L. I guess I'm thinking of the 75% rule, if that were to resurrect. Do you have any updated numbers or should we still assume if that were to happen that it has kind of a similar impact that you laid out last fall?
Jay Grinney - President & CEO
There is nothing new that we would put in there for that. Clearly, as time goes on, and as you heard us talk about the program mix towards more neurological and fewer knees and hips, that our overall compliance is moving north. So we're not in a position to say anything today about what the difference might be.
But, I think it's very fair to say that what we put out there last quarter would certainly be -- on an apples-to-apples basis for getting any additional growth would be sort of a worst-case kind of scenario. Because as we move into a higher overall compliance number for the Company, clearly then the downside risk is eliminated.
Having said that, the 75% rule, what I think is resonating with a lot of people in Congress is that we have already paid for that. That has come and gone. And I know that that -- there are people out there and the nursing homes love to flog the 75% rule, and if I was in their shoes I'd would probably be doing the same thing. Because everything else is looking pretty bleak, so you've got to find something.
And, I just think that that is something that doesn't have any traction anywhere except the White House. And it doesn't have any traction at CMS. It doesn't have any traction on the Hill. If you bring up 75% rule with most members of Congress that have been around for any period of time, they roll their eyes and say, please do not -- that's dead and gone. That's buried. You paid for it.
So, it's out there, and every time Obama puts out a deficit reduction plan or puts out a budget, it's going to be there. So everybody just ought to know that it's going to be there. What I say is, look at the track record of how many Obama budgets have been passed since he was brought into the administration and made President.
This thing is DOA. It's not going anywhere. So you know we -- we don't spend a whole lot of time worrying about it.
John Ransom - Analyst
Okay. And it was kind of interesting, the investor reaction this spring versus last fall. It was kind of (multiple speakers) as a nonevent. The second question, could you update us on E&Y and any partners there?
Jay Grinney - President & CEO
Well, our general counsel is up in Delaware trying to move through the logjam in our CONs. So -- and I'm sure he's listening in. He's about ready to cringe, I'm sure. But what I can say and what he's told me I can say is that the process is entirely at the discretion of the administrative law judges. We continue to believe in the strength and the validity of our claims and we are pursuing them aggressively.
What he doesn't want me to say -- and I always get in trouble when I say this is -- I still believe that we have much more incentive to get this done than E&Y does. And so, every time I say that, we get a nasty letter from E&Y's lawyers. I'm sure we're going to get another one. But that's -- I believe that. That there is no incentive for them to get this thing resolved quickly. But we have a lot of confidence in the strength of our claims. We continue to press them hard.
But, the process and therefore the timing of resolution is completely outside of our control. It is exclusively under the jurisdiction of three administrative law judges -- three judges, arbitrators, who are arbitrating the case.
And the only other thing I would mention is, think about how long this has been going on -- or maybe you don't want to, but it's been going on a very long time. Think about how much information those judges are going to have to wade through in order to make their decision. So, who knows?
I think the takeaway for everybody ought to be -- and we've been saying this now for about 1.5 or two years -- there is nothing in our growth plans, there is nothing in our business plans, either one year or five year, that assumes we are going to get anything. When we get something from this, if we do, and we certainly hope that we will and we certainly believe we should, we will be looking at how to deploy that.

A.J. Rice, Susquehanna Financial Group.
A.J. Rice - Analyst
Maybe just an operating question and then a philosophical one. On the operating question, I know you said the rate increases for the wages is running about 2.5% and a half day off that you gave people. Maybe can you comment more broadly on particularly therapists, but what you're seeing in terms of productivity turnover. Is that relatively stable at this point or has it crept, has turnover crept up? Any comments along those lines?
Mark Tarr - EVP & COO
Hey, A.J., this is Mark. I can tell you that we have not seen dramatic change in it of any kind in the marketplaces relative to therapists or nurses. If anything we've been in pretty good shape. We closely monitor our retention on both nursing and therapy, and we've not seen that pop up nor have we seen a pressure in wages going forward.
You've heard us talk in the past in terms of retention specifically over our nurses. And that's essentially reinvesting in them through education and training particularly at our CRRN Program where, this past year, we are now in excess of 800 CRRNs which is the rehab certified nursing for RN component. And so having that has certainly helped us on the retention aspect.
A.J. Rice - Analyst
Okay, thanks, and then my sort of philosophical question, you guys have been asked a lot about capital deployment and this is a question I don't really have to ask too many people in the services area. But your leverage is getting down to the point where you could almost argue you're starting to be questioned whether you're underleveraged at 2.7 times debt to EBITDA.
Can you just comment -- I know I've heard your comments about capital deployment but what about the leverage and where you're going at this point and maybe that will drive some comments about buybacks and dividends and so forth. But you know you're getting down to just to a point where you're pretty -- the leverage is pretty low by healthcare services standards.
Jay Grinney - President & CEO
You're right. We are aware of that. We frankly think that that's healthy. And we are very content with the level of our leverage today in part because we really don't know what the future is going to be like. This suggests a philosophical question -- I'll venture off a little bit, but it's really no different than where we find ourselves in on a federal budget standpoint.
There have been times in the past where as a country we spend more than we were when we should have and now we're saddled with a lot of long-term debt that we've got to deal with. Well, as we look at 2013 and sequestration, we know that something is going to happen in 2 -- or we believe something will have to happen in 2014 and beyond.
The reality is that the course we're on as a country in terms of how much we're spending in healthcare and so on is just unsustainable. It is unsustainable.
So there is going to be some kind of a change at some point down the road and what we've tried to do is tried to create a balance sheet that will be able to absorb whatever changes comes our way and, more importantly, creates an environment to then lever up if we need to for purposes that will bring us long-term value. But right now, we don't see anything that's out there on the horizon that we would want to bring more debt onto the balance sheet.
We've managed this very conservatively. I would much rather be in the situation we're in today going into 2012 and looking at 2013 than, as I mentioned a moment ago, than be sitting there with 3.5, 4.5, 5.5 times leverage especially as you think about the rate environment going forward. I mean, how many --? I don't know about you guys. We don't think that this rate environment is going to be there forever. It would be kind of nice if it was on one hand, because you can borrow at low rates. I don't know where you would invest the money but it's not a sustainable environment. So we're trying to make decisions that are based on the long-term.
Mark Tarr - EVP & COO
I think it is fair to say, AJ, that when we look at our total leverage we really take into consideration three factors. We look at the leverage ratio and there we are at 2.7 times, which is where well within our three times target. Second is, we look at the composition of our debt capital and the fact that we have no maturities prior to 2016 well spaced diversified sources of funding because it gives us a lot of comfort there.
And the third is we look at the obligations represented by our lease properties in there because we own such a substantial portion of our properties we don't have the kind of lease exposure that adds to the overall leverage picture that many of our healthcare service provider peers do.
When you look at all of those for us, it certainly underscores the fact that further debt reduction right now is not a priority for us. We've arrived at the position we would like to be in. It gives us substantial flexibility so we're not going to be out there particularly with our debt trading at levels substantially above par looking to reduce that further.

Frank Morgan, RBC Capital Markets.
Frank Morgan - Analyst
I wanted to circle back on the pricing growth and that clinical mix shift that you've seen specifically in the quarter. I'm just curious. Is that something that's happened consciously? Has it been because of service line development in those [narrows] and those high acuity areas or is that just a natural phenomenon that has occurred?
Jay Grinney - President & CEO
That's been absolutely by design. This is something that we've been focusing on really ever since the new 50% threshold came out with the new conditions. As you know, Frank, you don't develop clinical programs and clinical expertise and then roll them out and see the benefit overnight. It's something that you have to do carefully and thoughtfully. You've got to test them and then deploy them and that's exactly what we've done.
Frank Morgan - Analyst
So there's a good argument to be made that this can kind of continue to perpetuate itself and perhaps this shift is not just a one-time blip?
Jay Grinney - President & CEO
I think that there is certainly logic for that.
Frank Morgan - Analyst
Okay. I think you all mentioned about remaining real estate opportunities for buybacks. But, kind of on that same subject. What about on just clinic closures? Anything else much left out there to clean up on the clinic side? Or are you pretty much there?
Mark Tarr - EVP & COO
This is Mark. As you know, we continue to look at each one of these clinics. Every time the leases come due but I think we've probably been through the majority of the underperformers. I think that we'll continue to have a number of going forward but I think that number will decrease over time and we'll end up with a core group of high-performing clinics.
Frank Morgan - Analyst
I've got you. One question and this will go back into that philosophical category given the low leverage here. I guess what do you got to see before you really decide to do something perhaps using your balance sheet to do it from a, be it a real aggressive share repurchase or I guess what do you have to see before you are really willing to risk levering up again?
Jay Grinney - President & CEO
There's a lot of clarity on the -- in the future that we have to see. We have to see what the election is going to look like and who is going to win. Frankly I don't think that whoever wins the White House is nearly as important as what happens in the Senate. You think about it, the Senate is just -- is one just big roadblock for getting things done. And so, we need clarity there. We need to have clarity on the next debt ceiling discussion debate, whatever you want to call it. Everything I'm hearing is that's going to happen at some point and I remember what happened last year when that issue was on the table.
So, I just think that there's a lot of macro issues that present a lot of macro risks for the country. And since -- when they're going to be looking at changes or reductions to expenditures, then they are going to be looking at Medicare. They always look at Medicare.
So we are just sitting here thinking not for what about this quarter or what about 2012. We're all sitting here -- we're all shareholders and we are sitting here. what do we need to do to position this Company to be successful three years from now? Five years from now? 10 years from now? Not knowing exactly what the landscape is going to look like but we do know some of the basic fundamentals of managing a company in difficult times and we're just -- we're not going to resist --. We are going to resist the temptation to just go out there and take a lot of risks.
You look some at some of our -- others in the healthcare space, they went out and they did a lots of acquisitions. We got criticized, why aren't you out there using the balance sheet to acquire these properties and they are at all-time lows and look at where those companies are today. They are limping along sitting there going, holy cow, look at the debt that I've got, look at the debt service. Am I going to violate a covenant?
We don't want to be there. We have gone through -- do you remember what it was like in our Company in 2004, 2005, 2006, 2007? Not too many people have had to manage in that kind of environment. We did and we learned a lot of lessons.
And so we are going to continue to be focused. We're going to continue to be disciplined. We're going to be conservative in our approach to the risks that are out there and I think we feel pretty good that we're going to be able to continue to post good numbers and growth and ultimately that's what we're doing. We're doing that for the shareholders. We're not doing that for who's trading in the stock today. We're really building this Company for shareholders over the long term.
Doug Coltharp - EVP & CFO
And Frank, I think it's fair to say that specifically you asked about what would cause us to redeploy a significant portion of the excess cash flow towards the share repurchases. That type of decision would have to be accompanied with a substantial diminution in the prospects for compelling growth opportunities in the core ERF business and right now we see that pool of opportunities increasing, not decreasing.
Jay Grinney - President & CEO
I kind of like these philosophical questions because we can go off on these tangents.
Operator
Rob Mains, Morgan Keegan.
Rob Mains - Analyst
I just have one question and that labor efficiency. Your EPOB metric continues to improve. Is there a point where you think you hit a sticking point with that?
Jay Grinney - President & CEO
No, frankly we don't. There -- obviously there is going to be at some point a point that you can't move beyond. But, you know I guess our thinking is, we always have to find ways to improve and we don't know today, frankly, what the potential benefits of this clinical information system might yield for us. We're certainly not making this investment to trim labor costs. We're making this investment to increase the efficiency so we can see more patients.
And, so that's always going to be part of our business plan is improve productivity, improve productivity. But we are going to do that by giving our employees the technology that will enable them to do that.
Doug Coltharp - EVP & CFO
Rob, you may have heard us talk in the past about our beacon system where we are able to provide the field and our managers in the field with virtually real time feedback in terms of whether labor exists and almost to the point of to the prior shift so as we have volume fluctuations we're in a much better position to adjust the labor to fit the volume fluctuations. And that's really been our key to continued success and buying productivity.
Mark Tarr - EVP & COO
The other factor that will influence EPOB over the longer time frame is the accelerated de novo activity. In the near term because we'll have more hospitals in the ramping phase that could put some negative pressure on it. In the longer term as a higher proportion of our hospital base becomes these new hospitals which are built with the same footprint -- a prototype, if you will -- we should see enhanced labor productivity.
Rob Mains - Analyst
That's a great point, thank you.
Mark Tarr - EVP & COO

Operator
Whit Mayo, Robert W. Baird.
Whit Mayo - Analyst
Thanks for sliding me in. We've covered just about every question I had but I was just curious if you made any comments on the commercial mix in the quarter. And Jay, maybe just broadly, what are your contracting terms now? Have they meaningfully changed and, you know this whole conversation that's evolving about narrower networks, is it making your way through the door at this point? Just kind of curious on that broader topic.
Jay Grinney - President & CEO
You know, our commercial pricing is still in that 3%, 3.5% range. It really hasn't changed that much. You know, we don't see a lot of commercial patients because if you look at our payer mix, of that 20%, a good portion of that is Medicare -- managed Medicare and those patients are shifting out of managed Medicare into traditional.
So if you look at in poorer 2011, in the fourth quarter, we had about 20% -- 19.5%. About * percentage points of that is managed Medicare. So you're talking about a fairly small amount where patients that were not a big spend for the payers and so what we're seeing is pretty steady pricing environment. In terms of the more narrow networks I'm going to ask Mark to respond with what he's seeing there.
Mark Tarr - EVP & COO
We haven't seen a real change in the overall networks where all the major payers you would expect out there make up our largest percentage. I will say that over the years we've put a real effort into just having a better cooperation -- not really cooperation but relationships and building relationships with each of these payers in all of our major markets. And that's been a key to success for us because every time we go out and talk to these payers we also bring our quality metrics and to really make that value proposal to them where our quality comes into play.
Operator
Gary Lieberman, Wells Fargo.
Gary Lieberman - Analyst
You guys have done such a good job on the discharge growth for a while now that it seems like maybe we're starting to take it for granted. Can you talk about -- is there a limit -- is there a point where incrementally it becomes more difficult to continue to take share? Or should we really not worry about it and you guys feel comfortable that you'll continue to be able to do it?
Jay Grinney - President & CEO
We appreciate the comments on people taking things for granted because it's one thing to say something. It's another thing to actually make it happen. And there's a lot of execution. We've got a lot of a tremendous focus on doing just that.
You know, I think that the market share gains will in part continue for really indefinitely. But remember that the underlying demand, unlike acute-care hospitals or other providers, the underlying demand is pretty steady and it's driven by the aging of the population and the inevitability that occurs -- the older you get, the more you have these kinds of conditions that we treat and in the population as a whole. So if there is a 2% sort of fundamental underlying growth trend that is embedded simply in the aging of the population that gives us kind of a baseline, if you will, to build our long-term expectation.
And so, we think that there is still a lot of opportunity out there and a lot of it is going to be going up against other rehabilitation providers. But, frankly, a lot of it is going to be also continuing to take share from nursing homes.
Gary Lieberman - Analyst
Okay. And then in the quarter you guys had adjusted the guidance at the beginning of January for EBITDA to [455 to 458]. You still had some nice upside in the quarter. Can you maybe just talk about what specifically was the -- you came in at [466]. What was the upside to the high-end of the adjusted guidance?
Doug Coltharp - EVP & CFO
Gary, it's Doug. It was really in the two insurance accrual items that we referenced. We had favorable outcomes regarding our year-end actuarial review on the general professional liability and then we also had a favorable outcome on the worker's comp. And heading into that investor conference where we had updated the guidance at the first week in January we just didn't have a handle at that time on where those accruals would shake out.
Operator
Kevin Fischbeck, Bank of America.
Kevin Fischbeck - Analyst
I guess when we look at the EBITDA and the cash flow growth in 2012, it's a little bit below your targets but that makes sense, given maybe the comp obviously tough particularly on the free cash flow side. But you guys feel good about those numbers longer-term and I just wanted to see if we could talk a little bit about 2013.
Just looking at the sequestration cuts that you've targeted about $30 million, it seems like it's going to be hard to hit those longer term targets in 2013. Now you mentioned some offsets potentially I guess on the de novo site coming in but I would think that would add more to revenue than it would to profit. Is there something else in 2013 that's going to come in and help offset those cuts that we should be thinking about? Or is it more it might be a little bit soft in 2013 but 2014 and 2015 will pick up and you feel good about the longer term growth?
Jay Grinney - President & CEO
Yes, you're right. We shouldn't be talking about 2013. And with respect to 2012 guidance, remember what the guidance -- you made it sound like those numbers are already cast in concrete. That 2012 is going to be right on those -- right on the guidance.
As you know, there are -- there is really kind of two at least two camps for how to handle guidance. Some guys like to go out there and thump their chest and talk how great the year is going to be and then they find themselves having to walk down guidance at some point down the road. We've never had to do that. We've never had to do that. And we don't expect that we're going to start this year because we try to put out there on a realistic candid transparent way, here is what we believe we can do and in a high degree of confidence. And, that's the approach that we've taken.
So, guidance of that and if you saw the release and heard our comments, it is initial guidance and it's based on where we ended the year and now we've got about five weeks out of 52 weeks that we have operational knowledge of. So, it's -- it is always a discussion that we have every time we put out guidance but, again, we never want to be in a situation where we have to walk that back down because getting a short-term pop or an atta boy for great guidance to us is meaningless.
What we do is we are building the Company for the shareholders and we want the shareholders to appreciate the value that we are creating. 2013, what we've said is our business model for the 2012 through 2015 timeframe, that CAGR, those CAGRs are solid. We feel very good based on what we know today so we're not going to comment on 2013. We're six weeks into 2012, and that seems a little bit of a stretch.
But let's focus on 2012. We had a great year in 2011. We've got a great start in 2012 and we are excited about the opportunities that are out there to continue to grow this business.
Kevin Fischbeck - Analyst
Yes, I think that's a fair point that going back to things we take for granted usually you guys do beat your guidance pretty nicely to begin the year. I guess two quick clarifications, you mentioned in the press release that your volume assumption assumes some market share gains. And I just wanted -- and you mentioned in a conference call you think 2% is kind of what the industry is growing so your ability to get to 3% on a same-store basis would be -- the delta there would be market share gains. Is that the way to think about it?
Jay Grinney - President & CEO
Yes and the 2% is the -- is what the underlying 65% plus cohort is growing at and that's -- we use that as really sort of as a placeholder for what we think the underlying market is growing at. And so yes, anything above that is going to be market share gains and then, on top of that, any new store contributions that we might have.
Kevin Fischbeck - Analyst
Okay and then the IT expense for 2012, this is a multiyear rollout so should we expect a similar $4 million per year going forward? Is that weighted towards one year or another?
Doug Coltharp - EVP & CFO
It will increase modestly as the number of hospitals that are rolled out onto the system increases in subsequent years.
