Good afternoon. My name is Kim and I will be your conference facilitator today. At this time, I would like to welcome everyone to the DaVita HealthCare Partners fourth-quarter 2014 earnings call. (Operator Instructions). Thank you.
Mr. Gustafson, you may begin your conference.
Jim Gustafson - VP of IR
Well, thank you, Kim, and welcome, everyone, for our fourth-quarter conference call. We appreciate your continued interest in our Company. I'm Jim Gustafson, Vice President of Investor Relations. And with me today are Kent Thiry, our CEO; Garry Menzel, our CFO; Jim Hilger, our Chief Accounting Officer; and LeAnne Zumwalt, Group Vice President.
I'd like to start with our forward-looking disclosure statements. During this call, we may make forward-looking statements within the meaning of the federal securities laws. All of these statements are subject to known and unknown risks and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements.
For further details concerning these risks and uncertainties, please refer to our SEC filings, including our most recent annual report on Form 10-K, and quarterly report on Form 10-Q.
Our forward-looking statements are based on information currently available to us, and we do not intended, and undertake no duty, to update these statements for any reason.
Additionally, we'd like to remind you that during this call we will discuss some non-GAAP financial measures. A reconciliation of these non-GAAP measures to the most comparable GAAP financial measures is included in our Form 8-K submitted to the SEC and available on our website.
I will now turn the call over to Kent Thiry, our Chief Executive Officer.
Kent Thiry - Co-Chairman and CEO
Okay, thank you, Jim, and greetings to all. Thank you for your interest in our enterprise. In the fourth quarter we had solid results, all sides of the house. Kidney Care OI, $419 million, but that includes the net $29 million benefit from recognizing some deferred Medi-Cal revenues; so $390 million without that. And HCP OI, $33 million, both results within our previously provided guidance ranges. We'll cover clinical outcomes first, as we do every call. We are, first and foremost, a caregiving company.
CMS issued final QIP results on the Kidney Care side of the house recently. Once again, we led the industry. Only 1.5% of our clinics had a 2015 penalty, versus the overall industry's 5.6%; in other words, 73% more. This means we've outperformed the rest of the industry each year since that program began four years ago. And, in fact, we ranked first in three of four QIP categories this time.
We also are leading the industry in 2015 star rating results, with over 50% of DaVita facilities receiving a star rating of four or five, versus 21% of the rest of the industry. So, we're very proud of these results. And while no particular clinical metric by itself, or system by itself, is perfect, in aggregate this is indisputably a strong performance for our patients and for the system.
And we hope CMS continues to report clinical metrics, and we'll work on them to do so, and work with them to do so.
On the HealthCare Partners side, similarly strong news: over 800,000 patients now for whom we take comprehensive care. If we just grab Nevada, one of our three largest markets, and look at cancer screening and diabetes, we have a four or five star across all of our Medicare advantage patients, including -- here some other factoids -- 70% of our patients receiving colorectal cancer screenings compared to a national average of 65%; and 63% of our diabetic patients with cholesterol scores below 100. Both of those are five-star scores, and that's compared also to a 55% national average.
So, for the clinical outcomes throughout the enterprise, very strong. We take it very seriously. And in all these cases, healthier patients leads to savings to America's taxpayers, hopefully a value added that we can increasingly monetize for you.
I'm going to talk a little bit about HCP operating performance now, and expected, and Garry will talk a little bit more about Kidney Care. HCP, $33 million in OI, right in the middle of the guidance for the quarter.
But let's hit the bad news right up front. And that is that CMS may make multiple changes to Medicare Advantage reimbursement. And, in aggregate, this could mean that HealthCare Partners' 2016 OI could be below, and even well below, 2015. So, unambiguous potential bad news on that side. We incorrectly handicapped the Medicare Advantage reimbursement cuts last year, and I apologize for that. I got it wrong.
This actually is becoming a strategic issue for Medicare Advantage, in our minds; that it is crucial for CMS to protect the incentive to innovate to create health, where now there is sickness, and reduce risk where it is high for these patients. We hope they realize that in their near-term decision-making.
Now let's switch to the good news front, and here I will make four significant points. One has already been referred to: this strong clinical outcomes. Two, in our legacy markets, MA enrollment was up 7% year-over-year, meaning January 2015 over January 2014, excluding acquisitions. And if you include in-market acquisitions, it goes up to 10%. So that's fact number two.
Fact number three, in Albuquerque, New Mexico, MA enrollment a year ago was 2,500. It is now about 11,000. And fee-for-service visits per provider are up 20% from last year's low point.
And then fact number four, on the positive side of the lecture, we told you 18 months ago that we were going to be exploring four different segments: growth through IPAs, growth through payer partners, growth through health system partners, and growth through acquiring prominent medical groups.
We did the Phoenix IPA back right around that time. And since that time, we've done a significant payer partnership, a significant health system partnership, and a significant acquisition of a prominent medical group.
On the payer side, Tandigm is our 50-50 JV with Independence Blue Cross in Philadelphia, the largest health plan in that region. Now, over 275 PCPs signed up, another 75 joining within about a month. We currently are taking care of 16,000 Medicare Advantage patients, 53,000 commercial patients, about $400 million in annualized revenue being managed in that partnership.
The next segment, health systems, we've got our 50-50 JV with Centura, partnering in Colorado. And there, it's a very substantial number of doctors. They alone have about 340 employed physicians, a mix of PCPs and specialists, as well as a broader network. That's Centura, the largest health system in the state of Colorado.
And then the last segment, leading medical groups: as many of you will recall, we did acquire the leading group in Colorado Springs -- Colorado Springs Health Partners, with 51 PCPs.
So the message here is that 18 months ago, 20 months ago, we said we were going to explore growth models in each of those four segments. Now, 18 to 20 months later, we are doing just that with a strong entry in each one of those segments in order to explore the most capital-efficient, risk-adjusted, optimal ways of growing as the years go by.
We continue to be very modest in our business development investment, although it is growing incrementally. Having said that, however, the activities are quite robust. In particular, we're in discussions with several major health system; and in particular-particular, in Southern California, in some very interesting discussions with a few different health systems. And we look forward to deciding which ones to actually drive to closure, and might do some very interesting things.
And then separate from health systems, we're also talking to several high-quality medical groups in a serious way. Now, one never knows what's going to happen with the business pipeline. But the quality and quantity of the conversations we're having is better than ever before. Our business development capability, as I said, is still quite modest. And, hopefully, over the next year or so, that will change. Although right now, we couldn't deal with any more effective business development, since we're pretty much at capacity.
With respect to overall guidance, it is $1.75 billion to $1.9 billion, which is relatively flat. (technical difficulty) care operating income, $1.525 billion to $1.625 billion; and HCP operating income, $225 million to $275 million.
I would like to reiterate the comments I made last earnings call, and that is, we face two serious headwinds right now for the enterprise. Medicare reimbursement on both sides of the house under a lot of pressure in different forms. And on the Kidney Care side, a tough commercial pay environment as you look out over the next few years. Not so much because of any change in negotiating dynamics or leverage, but because of architectural changes in the way the healthcare system is working.
When you put all that together, as we said last earnings call, there is a real risk that 2016 OI could be down from 2015 at the enterprise level. Now, even in a scenario where OI is flat, if we just take that premise for a moment, if you look out over the next two years between our current cash balance and our free cash flow, and then you take out maintenance CapEx, still assume very robust dialysis de novos, and we make our mandatory debt payments. So after doing those three things, business as usual, we would still have $2.4 billion in cash to deploy in whatever way we thought was best for you and for the long-term strategic value of the enterprise -- so, acquisitions, buybacks, et cetera.
We very much look forward to discussing our longer-term strategic positioning and our outlook at our Capital Markets Day in New York City on May 5, in conjunction with our Q1 earnings call. More details will come out soon. And we hope to see many of you there and satisfactorily answer all your questions.
Garry, our CFO, please take over.
Garry Menzel - CFO
Thanks, KT. Starting with Kidney Care, non-acquired dialysis treatment growth in the quarter was 4.6% when normalized for days of the week. Kidney Care operating profitability was up $11 million sequentially, primarily as a result of two factors: first, the $29 million net favorable impact resulting from the revenue recognition of certain Medi-Cal payments received in prior periods. And, second, an unfavorable impact from a $3 per treatment increase in dialysis in lab segment G&A, which was caused by normal seasonal increases in G&A spending at the end of the year; and intentional, non-recurring project investments in IT during the quarter. It is worth noting that despite the higher G&A spend in the quarter, G&A per treatment was down nearly 9% in 2014 compared to the year before.
International losses were $16 million for the quarter and $42 million for the year, in line with prior guidance. We continue to expect international losses for 2015 to be similar to those in 2014.
For the overall enterprise, our debt expense was $98 million in the fourth quarter. Our income attributable to non-controlling interest of $42 million was approximately $5 million higher than our normalized run rate, due to recognition of the Medi-Cal deferred revenue I discussed earlier.
Next, the effective tax rate attributable to DaVita HealthCare Partners of 33.3% in the quarter was lowered due to, one, a reduction in our tax reserves; and two, the incorporation of federal and state tax credits that were retroactively enacted by Congress in December 2014. We expect the full-year tax rate for 2015 to be in the range of 39.5% to 40.5%.
I would also like to provide a few reminders as you model the normal seasonality for the first quarter of 2015 in our business. In Kidney Care, first, Q1 2015 contains three fewer treatment days than this past quarter, so you should expect lower revenue and higher fixed costs per treatment.
Second, our payroll tax caps reset at the beginning of the year, which leads to higher costs of $1 to $1.50 per treatment. And third, Q1 will not benefit from the Medi-Cal revenue that was recognized in the fourth quarter.
At HCP, operating income fluctuates from quarter to quarter, due to the seasonal needs of patients. And Q1 operating income tends to be a bit lighter than the full-year average. Also, the severity of a flu season can have a material impact on medical costs.
We are seeing higher utilization right now, with the flu vaccine being only 23% effective, according to the CDC. However, it is still too early to know how the flu season will play out. But we estimate that it impacted our operating income by $2 million to $4 million in Q4 2014 versus the comparable period in 2013.
Turning to cash flow, we continue to generate strong cash flows, as operating cash flow was $199 million in the fourth quarter, and $1.728 billion for 2014. Excluding the after-tax impact of payments made in connection with the previously announced settlement with the government, this was within our guidance range.
We expect 2015 operating cash flow to be between $1.5 billion and $1.7 billion, lower than 2014 but in line with our historical trends. As always, this guidance range captures a majority of probabilistic outcomes, but we could be above or below this range.
Finally, some comments on capital deployment. We continue to have a very strong cash balance. We are in the fortunate position of having various opportunities where we could deploy our capital in each of our business lines. We are constantly reviewing our capital allocation to make sure that we sustain the long-term health of the organization and achieve appropriate after-tax cash returns on capital.
We did not do any share repurchases in the fourth quarter, nor have we done any to this point in 2015. We felt that it was prudent to wait until after next week's announcement about Medicare Advantage rates before making any large capital deployment decisions. As we have said before, we favor a situational approach to capital deployment, and will continue to review our options.
And with that, operator, let's go ahead and open it up for Q&A.
Operator
(Operator Instructions). Justin Lake, JPMorgan.
Justin Lake - Analyst
I guess we'll start with Medicare Advantage. Kent, you discussed the fact that OI could be down at HCP next year, despite what seems like a robust Medicare Advantage membership growth environment. So just trying to understand, what kind of rate would it take for OI to be down next year, as we think about next week's rate release for HCP? And then can you give us an update on where you are with the contracting initiatives, to get plans to give you some offset here on the benefit side?
Kent Thiry - Co-Chairman and CEO
On the rate front, I'm afraid there's not a simple answer because there's so many variables that they are playing with now. They're playing with the coding intensity; they're playing with the benchmark rate; they are playing with the RAF coding, which we are particularly sensitive to because we have an above-average RAF. They're playing with the star system. And so, there's four, five, six different levers that they are thinking about pulling. And of course, the economics are a result of that net number at the end. And so, there's no magic single line to draw and correlate it to 2016 outcomes.
On the contracting front, we should have a better answer for you than we do. I know that we have picked up some significant incremental protections through the course of the year. But I can't translate it into a percentage of the book of business, or something like that. So why don't we just pledge, Garry, to have that for the next time around? I think it's been solid progress qualitatively, much better than where we were a year ago, but not close to done yet.
Justin Lake - Analyst
And maybe I can ask the --.
Kent Thiry - Co-Chairman and CEO
And Justin, just for example, the kind of thing -- so one that we signed recently, for example, any benefit design changes, we and the plan basically split them 50-50 up or down. The cost or the benefit of doing them is shared, and so we're aligned in terms of our microeconomic incentives.
Justin Lake - Analyst
Great. And just maybe a way to follow up on the rate side before I ask my other question. I know there are a lot of moving parts, as you said, but they are all going to net out to something. So I'm not asking for a -- to be clear, I'm not asking for all six components, Kent. I'm just thinking about a range.
Are you saying, like, can you say if the ultimate outcome is you add them all together and it's minus 5%, that's what's going to drive OI -- that kind of rate would drive OI negative? Or is it minus high-single-digits like you had in 2014, the 7% to 9%, I think you said? Just trying to put a ballpark around -- when we see this rate, how should we think about it for [the data]?
Kent Thiry - Co-Chairman and CEO
Okay, very fair question, to which we do not have a very fair answer. So why don't we take that under advisement? We've got capital markets in a couple of months. And by that time, what we'll know what they've done across all those things. And maybe going forward, we should always calculate that number. But I'm afraid, right now, spontaneously, cannot do that justice.
Obviously, our forecast is a product of a bottoms-up set of -- a mix of assumptions on every single one of those variables. But we don't have the magic index number that you're talking about.
Justin Lake - Analyst
Okay. My other question was on the commercial mix. And just trying to get an idea -- can you give us an update on where your commercial mix has trended through the year, and come out of 2014?
Kent Thiry - Co-Chairman and CEO
Yes, it's -- where there's some little ups and downs, it's basically been flat for three years or so now, which is much better than what happened to it a couple years before then. And we have hopes that if the economy continues to recover, that it will go up. But there's so much noise in the system now, compared to before, with exchanges and narrow networks and everything else, that it's not as linear a relationship as it used to be. But the answer to the narrow question you asked is, it's been more or less flat for 12 quarters in a row.
Justin Lake - Analyst
And so these impacts, as we've gone into -- we're a month and a half into the quarter now. I assume you're seeing some further changes from narrow networks, et cetera. Is there anything that you've seen over the last three months, let's say, including mid-February, that would give you any increased line of sight, versus where you were when you gave the guidance in terms of mix deterioration that seems to be embedded in guidance?
Kent Thiry - Co-Chairman and CEO
Yes, I hear you. Good question. The short answer is no; there's been no material development. We continue to get our normal commercial rates on exchanges, but we worry about competitors being willing to discount for exchanges. At which point, we would suffer from a reduction in our incremental growth rate. And I could go down a checklist. But the answer to your question is that if you think about the five or six or seven variables that affect mix and rate, there have been no material developments that represent any kind of discontinuity from before.
Is that responsive?
Justin Lake - Analyst
That's absolutely responsive. Thanks, Kent.
Operator
Kevin Fischbeck, Bank of America Merrill Lynch.
Kevin Fischbeck - Analyst
Just figured to follow up on that question there, I think the Company is well known for outlining all the risks that are out there that appear reasonable. But, oftentimes, you guys highlight things that don't actually come to happen, which is great to be aware of them.
But at the same time, trying to really get to the point here of -- is there something specifically that you're seeing? Have you seen -- because it really takes two to tango in this case of -- someone has to accept the lower rate. Some player has to be of the view that the business model that has historically served everyone is now upside down, and now it makes sense to change it.
And have you actually seen that happen, in at least small instances that make you think that there is a bigger risk here? Or is this just, hey, it's a risk because we're seeing hospitals do it, but we haven't really seen any indication that it's happening at all yet?
Kent Thiry - Co-Chairman and CEO
Fair. I think the answer is a little bit in between. Have we seen any clear, irrefutable evidence? No. Are there rumors of one or two of some consequence? Yes. So, it's a bit of a tweener. But, no, we cannot point to anything that we know of that would represent -- well, that's the answer to the question.
Kevin Fischbeck - Analyst
I guess it's fair to maybe not know how the competitors are necessarily priced. But do you feel like you are getting a lot more pressure from the managed care side, that their coverages with you have changed dramatically, and you're doing all you can to hold the line? Or has that not really even changed much?
Kent Thiry - Co-Chairman and CEO
That's always been a pretty unvarnished fistfight, and that continues. If anything, to some extent, in some cases, the conversations are less adversarial because we're bringing so much other value to the table now, with reducing hospitalizations, reducing mortality, and everything else that we're doing on the quality side.
So, you'd almost push it the other way. But then when you stare at the emergence of narrow networks, the emergence of ACOs, the emergence of exchanges, you look at all that stuff going on, you have to respect the fact that the architecture of the building is different. And to presume the same sort of outcome is just not prudent.
Kevin Fischbeck - Analyst
Okay.
Kent Thiry - Co-Chairman and CEO
But we are absolutely sticking to our commercial rates for exchange business.
Kevin Fischbeck - Analyst
Okay. And the data that you gave about Albuquerque, I think you said 2,500 members going to 11,000. What was ABQ at when you bought them?
Kent Thiry - Co-Chairman and CEO
Zero. They may have had some -- they certainly had Medicare fee-for-service.
Jim Gustafson - VP of IR
Yes, so I guess (multiple speakers). Well, I'm just trying to think, where are we, as far as them rebuilding the book of business or the revenue base? Because you're right, with more of a fee-for-service, you move them to capitation. But where are you in rebuilding the revenue base that they had when you first bought them? Are we back to where they were, or not there yet? How do you think about that?
Kent Thiry - Co-Chairman and CEO
Why don't we check, and get back to you within 10, 15 minutes on this call, Kevin?
Kevin Fischbeck - Analyst
Okay. And then just to clarify something you said about the growth in the legacy markets being up 7% year-over-year. Do you characterize legacy being Southern California, Nevada, and Florida? Or do you -- now that you've had New Mexico and Arizona, are they legacy now?
Kent Thiry - Co-Chairman and CEO
Yes, good point. Legacy is those three; and then sort of have phase 1 of new, which were those two that were done right around the time of the deal that had fairly tempestuous beginnings in Phoenix and Albuquerque; and then phase 2 new, which is the three that I referred to. So that's just -- from a terminology point of view, that's what we're talking about. And so the growth rate was in those three.
Let me go back for a second and just be clear on something; that ABQ had some MA patients, but was just treating them on a fee-for-service basis. We're now treating the 11,000 on a partial risk basis. And then, at some point in the future, we will move to full risk, as soon as our payer partner is ready.
Kevin Fischbeck - Analyst
Okay. And then just my last question. Obviously you've gone through ABQ and the fix there. Can you talk a little bit about Arizona, what went wrong, and where we are in the progress of fixing that?
Kent Thiry - Co-Chairman and CEO
Say the question again, Kevin?
Kevin Fischbeck - Analyst
Historically, you talked about obviously New Mexico not going well. We've covered a lot of what you have done there to fix that. It sounds like Arizona has not gone as planned, either. Can you just talk a little bit about what happened there, and where we are in the progress of returning that to normalized profitability?
Kent Thiry - Co-Chairman and CEO
Yes. Well, let me first just comment -- in aggregate, we have delivered what we said we would, I don't know, six, seven months ago, in that year-over-year there will be an improvement exceeding $25 million. So that's the aggregate net economic result as we committed to you it would be.
And then specifically in Arizona, we worked out an arrangement whereby a couple unprofitable plan populations got pruned in a very significant way, reduced by about 65%, 70% of lives, which eliminated a huge amount of losses for us.
Kevin Fischbeck - Analyst
Okay, great. Thanks.
Operator
Kevin Ellich, Piper Jaffray.
Kevin Ellich - Analyst
Kent, starting off with the subpoenas that were announced after the close, can you give us some more information? It really sounds like this might be about something else. Do you have any color for us?
Kent Thiry - Co-Chairman and CEO
I can't really say anything other than our release said. It's literally all we know. If I could read it to you -- which, of course, would be fairly redundant -- but we don't know anything else.
Kevin Ellich - Analyst
Okay. See, last fall, I think it was November, Medicare held an ambulance open-door forum. And dialysis patient transportation billing and coding was actually brought up on the call. I think there was confusion about the coding. So I'm wondering if they are trying to get information from you guys about that.
Kent Thiry - Co-Chairman and CEO
Yes, there certainly was a lot of noise around transportation in general, and then including in the dialysis space. We've had very clear policies for our people on that front for a long time, and do a very thorough job of reinforcing them all the time. And so we feel very good about that. And as you know, we don't do the transportation; we don't bill for the transportation; it's not our transportation. So what you're saying is all true. Nonetheless, we only know what we know, and we'll have to keep you posted as things unfold.
Kevin Ellich - Analyst
Sure, okay, great. And then can you give us some updated thoughts on Medicare's continual shift to the value-based reimbursement models and how you are positioned? And on top of that, we've seen you do a few deals over the last several months. You mentioned some on the call. But also the Camden Group acquired small consulting business as well. And wondering what your view is in participating in Medicare's Bundled Payment for Care improvement initiative, and whether you think it has legs or not.
Kent Thiry - Co-Chairman and CEO
Yes. We don't have any particular perspective on that program, so I won't waste your time with just saying some superficial pablum.
Kevin Ellich - Analyst
Okay.
Kent Thiry - Co-Chairman and CEO
Our Camden Group, which is, for those of you who don't know, is a consulting firm. It does superb work. They have a number of clients who are participating in the program. And so we're watching, and we'll continue to watch. But we're not, at this point, doing anything dramatic in that sphere.
Kevin Ellich - Analyst
Great. And then going back to some of Garry's comments, I think you mentioned you saw a $3 per treatment increase. How much of that is recurring? And then could you just recap again the $29 million Medi-Cal prior period increase? Where did that come from? And that's all I have. Thanks.
Garry Menzel - CFO
So I'll answer the first question. You may have to repeat the second question for me. The first question, as I pointed out in the per treatment increase, some of it was we did intentional, nonrecurring IT expenditures at the end of the year. And some of it were normal, seasonal increases. We're not breaking out how much of that is recurring. But I think you can assume on a G&A perspective that the run rate that we have for the average of 2014 is likely to be the run rate that we will have in 2015.
Kevin Ellich - Analyst
Okay.
Kent Thiry - Co-Chairman and CEO
And then the second subject, I think you asked about the $29 million. Is that right?
Kevin Ellich - Analyst
Yes, yes, that's right.
Kent Thiry - Co-Chairman and CEO
Yes, and what that is is Medi-Cal, which is Medicaid in California, instituted significant cuts back a while ago. It became -- it was litigated. And so in order to be appropriately conservative, prudent, we didn't want to realize that revenue. And then recently there were decisions which made it clear that the state would not claw back those dollars; and, hence, it was time to put them through the P&L.
Is that correct, Jim?
Jim Hilger - CAO
Yes, that's correct.
Kevin Ellich - Analyst
Great, thanks.
Operator
Gary Lieberman, Wells Fargo.
Gary Lieberman - Analyst
Maybe just to pick up on than IT cost, could you talk a little bit more, maybe, in detail about what it was, and how you think about whether -- when the decision becomes whether or not to capitalize costs versus running it through the income statement?
Garry Menzel - CFO
I don't think were prepared at this point to highlight what the individual IT costs were, and we certainly haven't made any decisions on capitalizing versus running through the P&L. It depends, of course, on the nature of the cost in terms of a variable versus fixed.
Jim Hilger - CAO
Yes, that's right, Garry. We follow GAAP from a capitalization standpoint. And the project spend in the fourth quarter was just more of an expense and maintenance type IT, as opposed to long-lived assets. It was just necessary spend that, for the most part, was not capitalizable.
Gary Lieberman - Analyst
Okay. And then on the revenue per treatment, you had some nice pickup. I don't recall if you said what that was from. But could you give us maybe more detail on what the growth in the revenue per treatment was?
Jim Hilger - CAO
RPT -- we call it RPT, revenue per treatment -- that is principally -- the rise in the quarter was principally driven by the recognition of the previously discussed California Medi-Cal revenue.
Gary Lieberman - Analyst
Okay, that makes perfect sense. And then maybe moving on to HCP. Kent, I think you said that at this point the contracts are structured so that if -- I guess what happened last time, where the managed care providers didn't pass along much, or any, of the increases to the beneficiaries, you guys what not take a disproportionate share of that. Is that on 100% of the contracts at this point, or that's on a portion of HCP's contracts?
Kent Thiry - Co-Chairman and CEO
It's just a portion. And that's where I conceded that we don't, around this table right now, know what the percentage is. And it tends to not be a monolithic number, either, because -- well, some of the contracts are now pure, in that it's 50% aligned up and down, even-Steven. Other ones have much more complicated formulas or corridors. And then some have no protection. And so all I can say is we moved from no protection to having a decent subset of our contracts with some or good protection. Alignment is almost a better word. But there is still a bunch that -- where we are exposed.
And it isn't that we suddenly wanted to reopen every single contract we had. First of all, from a capacity point of view, we couldn't do that. Second, you have some of our payers who don't want to do that, and then particularly for one term out of an entire contract.
And so it's a bit of a process, a little bit analogous to when we were starting to move to bundling in all sorts of our old Kidney Care contracts. That it took, in the end, 3 to 4 years for us to move from 0 to 10% that way, to 70% to 80% that way. And I think we're on the same kind of journey.
Gary Lieberman - Analyst
Okay. Are we maybe halfway there, or is there any way to try and guess where we are in that process?
Kent Thiry - Co-Chairman and CEO
I'm looking around, and nobody is confident enough to throw out an estimate. So, I think we'll just have to tell you at Capital Markets, with whatever precision we think is appropriate. But right now it's not a matter of our not being willing to disclose; it's that none of us knows the number, right around the table.
Gary Lieberman - Analyst
Okay. And then you had said you incorrectly handicapped the potential changes to MA, and you mentioned a couple of the individual items. Is there any more detail you can give us? Was there one thing that was more than another? Or what should we keep our eyes open for when the rates come out?
Kent Thiry - Co-Chairman and CEO
Well, I think it's -- the whole package. Any one of the levers can add up to significant money over time. So whether it's the acuity coding, also called the RAF scores; whether it's the benchmark rate; whether it's the coding intensity; whether it's adjusting the star system; that on the margin, that math gets to be a pretty significant of profits pretty quickly, which is why we are very worried that 2016 could be well below 2015.
And then the other point we wanted to make very clearly is that we did not handicap the dynamism around Medicare Advantage reimbursement rates correctly. And for that, I wanted to apologize and make very clear that I got it wrong.
Gary Lieberman - Analyst
Okay. And then once the rates come out, how long will it take you guys to go through that? And when could we expect to get some visibility from you on what the impact might be?
Kent Thiry - Co-Chairman and CEO
They will come out with up preliminary rule on most, if not all, of those variables on February 20, and then a final on April 10 -- April 6, excuse me. So, in between, there will be a lot of drama.
Gary Lieberman - Analyst
Okay. But I guess in terms of DaVita giving us some kind of guidance or direction, in terms of where the proposed rates came out, when might we hear that?
Kent Thiry - Co-Chairman and CEO
For that, that will be at our Capital Markets on May 5.
Gary Lieberman - Analyst
Okay. All right, thanks a lot.

Matt Borsch, Goldman Sachs.
Matt Borsch - Analyst
Not to beat a dead horse, but maybe just staying with the topic here. I just want to understand, is there something that maybe shifted your view on the Medicare Advantage rates for 2016 in terms of industry chatter or consultants?
The reason I'm asking I guess because the only real piece of hard information that we got in recent months, to my knowledge, is the preliminary trend factor. Which, as compared to a year ago, when in December of 2013 it came out with a very worrisome number. This time around, it was actually slightly positive.
So, I'm just wondering, is it because of where we are in the calendar that you are raising the issue now, or if there are [ventings] recently that have got you particularly concerned?
Kent Thiry - Co-Chairman and CEO
I don't think there's any clean answer to that, because obviously in staring at it there's a million different dots to connect from the conversations we're having with people in DC, and what other people are saying, and what people like you say and all the rest. So, there's no magical source of data that we have.
We do have more susceptibility than others on the RAF coding front because we have an above-average RAF because we have slightly older patients and we've had them for longer periods of time. And we're more disciplined in both collecting diagnoses as well as acting on them, which is why we have superb clinical outcomes. And so we're more sensitive on that score than others.
But then there's the other three, four, five variables. And right now our concern is that the administration may not realize how close they are to actually reducing the incentive for people to invest in Medicare Advantage, which has been the source of tremendous innovation, cost reduction, and clinical improvements.
In a lot of markets, it's estimated now that once you get MA penetration up into that 35%, 40% range, the ripple effect into affecting fee-for-service expenses is quite substantial. There was a guy speaking in DC today who is well respected, who talked about as much as a 9% spillover effect. And so we worry that they -- some of that may be trying to, if not kill the goose that's laying the golden eggs, cut off a leg.
Matt Borsch - Analyst
And as you look at the -- you've talked to this, and you've made some progress on renegotiating some contracts. But do you think that there is some fundamental unfairness in the way that the rate pain comes down between the plans and what you're facing as a delegated provider group? And is that something that might actually make you think differently about being delegated versus going on your own, with your own MA plan?
Kent Thiry - Co-Chairman and CEO
Well, that's a very powerful question. I am sure that at some point, in some markets, we will be a plan. And this is no different than what I've said before. We prefer to work in alignment with existing plans, and feel that's the best way to more quickly get to a good place for everyone, including the patient and the physician networks. But I predict with a high level of certainty that at some point, in some market, we will be a plan.
Matt Borsch - Analyst
And maybe by --.
Kent Thiry - Co-Chairman and CEO
Did I answer on enough of that, or was there --?
Matt Borsch - Analyst
Yes, you did, absolutely. And I just -- sorry, just one more follow-up, sticking with this theme, which is -- where are your end markets? And there are -- and this is happening in markets that you're not in -- but major hospital systems that are forming their own plans. How are you working around that? Are you willing to subcontract with those plans, versus that maybe shifting the landscape for you. I realize that's a very open question, so whatever color you can give on that would be great.
Kent Thiry - Co-Chairman and CEO
No, no. Your intuition is exactly right. I would think that, as the years unfold, we're going to have some health systems as our partners. And whether it's their plan and we're a subcontractor, or it's our plan and they're a subcontractor, or it's both our plans and we're fully partnered, that's going to happen.
And for a lot of the health systems that are starting to put a plan on the shelf, we're one of the phone numbers they call. Because once you do that you really get pretty intense about actually managing the population. And so, you're absolutely right. And that's why 18 months ago we said one of the R&D segments we were going to play with, from the perspective of developing growth models, was the health system segment.
And that's why we're working with Centura. That's why we're talking to one or two others already right now. And we may very well, in some of those cases, be doing a plan with them or a subcontractor to their plan.

Darren Lehrich, Deutsche Bank.
Dana Nentin - Analyst
This is Dana Nentin in for Darren. As it relates to your outlook, I was wondering if you could confirm what, I guess, if at all, you are assuming on P&L investments as it relates to the HCP business, as well as your international or ancillary businesses.
Kent Thiry - Co-Chairman and CEO
On international, I believe our guidance is that 2015 will be about flat to 2014. What you have going on underneath that calm exterior is some nice profitability improvements in some countries, offset by the increased expenses as we ramp up in Saudi Arabia, where we won that huge government contract for 5,000 patients. So, that's the mathematical answer to that.
As to the dollars we're investing in new capabilities in HCP, I do not know the number offhand. It is not a small number, because we think the potential for creating long-term competitive advantage is quite substantial.
Of course there's an element of subjectivity. If you add someone in cyber security, does that count as new capability that is strategic? Or is it just a new recurring normal operating expense, or is it something in between?
So, I don't -- for capital markets, perhaps, we could put something on the table that will give you a sense of what is incremental expenses that are very much tied to creating new capabilities for the future, as opposed to just supporting existing.
And by the way -- if I can just break in, Dana -- that someone asked a while ago about ABQ revenues. And they are back to approximately 80% of their peak, which is a significant improvement from two years ago at the low.
But, back to you, Dana.
Dana Nentin - Analyst
Okay, great. And then I guess just as it relates to a couple of your business segments. On the DaVita Rx business, can you update us on the revenue in that business? Or maybe if you could size it in any way, like patients served?
Kent Thiry - Co-Chairman and CEO
We, Dana, up to this point, have not disclosed Rx revenue. And so I will not make a spontaneous decision to change that policy, but we'll take it under consideration before Capital Markets. It has grown; we will say that. It's a material amount of revenue.
And what was the related question?
Dana Nentin - Analyst
If you could size it in terms of maybe patients served.
Kent Thiry - Co-Chairman and CEO
Let me see if I get permission to share that. Let me put it on mute for one second. We're going to -- it's approximately 65,000 patients. And people are going to check and see how out-of-date I am, or how far off I am, but that gives you a ballpark sense.
Dana Nentin - Analyst
Okay, great. Thanks a lot.

Gary Taylor, Citi.
Gary Taylor - Analyst
I just had a couple questions. The first, just going back to the conversation on commercial reimbursement. Now that EPO is bundled on the government side, and I think largely bundled on the commercial side, government's giving you zero on rates, this modest -- is it fair to say that this modest growth in revenue per treatment is purely being driven by the third of your revenue or so that's commercial revenue?
Kent Thiry - Co-Chairman and CEO
Yes.
Gary Taylor - Analyst
And so, that seems to imply maybe your commercial rate growth is in the 2% range. Is that -- what did that look like a few years ago? Has that changed?
Kent Thiry - Co-Chairman and CEO
Boy, I can't -- Garry is too new to know the past. And I am not going to be able to confidently say what year-over-year increases were, three or four years ago. If I had to guess, I would say on a net basis, probably higher than that by a bit. That would be my -- I think the odds that that statement is directionally true are probably 80%.
Gary Taylor - Analyst
I know that drug reimbursement was a driver on the overall commercial revenue per treatment historically, so you have to parse that out. This comment, though, about the narrow networks, is that creating some pressure on your out-of-network revenue? Is that an element of the discussion at all?
Kent Thiry - Co-Chairman and CEO
Could you please repeat the question?
Gary Taylor - Analyst
Yes, your general comment on commercial rate pressure, driven by some structural changes in the industry. And I think you mentioned narrow networks. And I just wondered, is there -- DaVita still have a material portion of out-of-network revenue? And if so, is that something that's being pressured by the narrow networks?
Kent Thiry - Co-Chairman and CEO
Certainly out-of-network business is always under pressure. I don't think we've ever disclosed our precise percentage. It is, in general, much lower today than it was before. And so I think we'll probably leave it at that.
Gary Taylor - Analyst
Got it. Just two other quick ones. On the $33 million HCP operating income, I think historically -- I'm not sure if you did this last quarter; it seems I remember maybe the 2Q -- but you had talked about what the new market losses were. Is there an update for that number that's embedded in the $33 million?
Kent Thiry - Co-Chairman and CEO
Yes, I think we're trying to move away from some of that parsing. We did it because at the time it was necessary for you to have a fair picture of what was going on; and, therefore, we did it. At this point we think you've got a fair picture without us going into that kind of detail, which, A, can be misleading; and, B, sometimes is counter to your interest in terms of how it affects those market dynamics.
Gary Taylor - Analyst
Okay, fair enough. Last question. I just want to confirm the $11 million foreign currency headwind is only in other comprehensive income, and doesn't impact the reported EPS or the reported operating income or the international operating income loss. Is that correct?
Jim Hilger - CAO
Yes, there is some that ran through other income, which is the same line that interest income is in, and that was about $5 million for the year and about $2.5 million for the quarter, of a headwind due to the strengthening dollar. The rest that you see runs through OCI.
Gary Taylor - Analyst

Lisa Clive - Analyst
A follow-up question on your ancillary services business. It sounds like from a prior question that much of the growth in recent years has come from DaVita Rx, which is performing quite nicely. Could you also give us an update potentially on the number of patients you have on an integrated care platform today? And really how you see that shaping up in the next few years?
Kent Thiry - Co-Chairman and CEO
Yes. We don't break that out. And it's not to be difficult, but it really gets difficult to categorize. Because you can have a pretty tiny pay-for-performance bonus and then define that as a value-added managed care type contract, all the way to being globally capitated. And so, I think from a strategic point of view, the number continues to grow, and the weighted average depth and robustness continues to grow. But not in a way that would affect your modeling one way or another, which is why we don't think there would be any particular utility in us arbitrarily defining what counts and what doesn't.
So it's very nice progress. It helps with relationships. It's consistent with our mission. Someday we hope that we can monetize our capability in a way that makes it worth talking about with you. But right now, it's just not.
Lisa Clive - Analyst
Okay. And as an update to that, could you give us an update on anything that is potentially going on with the ESCO program? Or is that just completely on ice right now?
Kent Thiry - Co-Chairman and CEO
I think -- I'm going to say words that one should never say. I think it's going to go into effect soon. And that's just because I was in DC recently. And so I think it's going to go in soon. We are participating out of a sense of citizenship. It's not a scalable program as currently defined.
However, we totally applaud CMS for doing all the work to get it where it is; and in particular, Dr. Conway and others. And hopefully we can use this as a platform to take that next step to a scalable program which will really transform kidney care in America, dramatically improve quality, save a bunch of money, be good for shareholders, be great for families, key people at work. So we're inching towards the promised land.
Lisa Clive - Analyst
Okay, that sounds very intriguing. Just one follow-up question. It looked like from the initial proposals that an entity of your size could maybe end up with something in the ballpark of 6,000, 7,000 patients. Is that the right way of thinking about it?
Kent Thiry - Co-Chairman and CEO
It's been so long since we submitted the details. To be honest, I don't remember. Those numbers could be about right. Now, remember, CMS gets to pick which proposals for which markets. And it is sometimes difficult to forecast then, even within one of those selections, exactly what the enrollment is going to be. But that may be -- it's certainly not that we're going to have 20,000 patients, and it's not that we're going to have 1,000. We could have zero if they don't award anything to us. We'd be surprised and disappointed at that. So it's not 25,000 and it's not 1,000, but beyond that I don't really remember.
I think where CMS was is that, in total, they wanted to have about 15,000 patients in the pilot. Now, they may have gotten more aggressive on that, but that used to be the number. And if you assume that if we're 35% of the patients in America, we'd be 35% of the ESCO patients, that would put us right about exactly where you were estimating.
Lisa Clive - Analyst
Great. That's very helpful. Thank you.

Margaret Kaczor - Analyst
It's actually Margaret Kaczor in for Scott. Kent, you had mentioned at the beginning of the call that you guys were really going to invest into four main areas for HCP -- the ICPs, the JVs, et cetera. Which of those, to date and going forward, do you think will have the best ROI? Which one will have the fastest growth in MA patients? And if you were a betting man, which are probably not, which of the four horses would you want to really grow the most on a 5- or 10-year basis?
Kent Thiry - Co-Chairman and CEO
Okay. Well, I'll first do a qualitative answer. They will all develop slower than you would like. But then separate from that, if we compare the medical group segment to the health system segment to the payers segment to the IPA segment, the one that we're -- by virtue of our DNA -- most compatible with and attracted to is the medical group segment. We're a physician caregiver organization. And so medical groups are like finding cousins, or long-lost brothers or sisters for us, as opposed to the other categories.
And so, I think that's the one that we're philosophically drawn to. But as to which one will end up being the best vehicle for good risk-adjusted return on equity, it's just too soon to tell. If you forced me to bet right now, even though I'm not a betting man, I would go medical groups.
Margaret Kaczor - Analyst
Okay, thank you. And then just one more for me. Anything that you guys are seeing due to some of the weather the East Coast is getting? Are you seeing people maybe miss some of the dialysis appointments? Anything on ATP? Thank you.
Kent Thiry - Co-Chairman and CEO
On the weather, in general, our teammates do amazing things to help their patients get dialyzed. And I mean amazing in terms of picking them up, in terms of clearing out parking lots when there's no public services to do it, working early, working late, helping babysit for each other's kids so somebody can stay late. I mean, it is inspiring to see what our people do. As a result, almost always, almost everyone gets their treatments.
Does anybody around the table know anything different this time?
Jim Hilger - CAO
I think no. And we do always see a few -- a higher amount number of missed treatments every winter. And it just depends on where the storms are and stuff. But there is a little seasonal impact every winter.
Kent Thiry - Co-Chairman and CEO
We just had -- there were floods in Malaysia, and so we had people that were sleeping and sitting on their roofs because f the water filled their houses. And our teammates continued to travel by boat to a stranded dialysis center to dialyze, with at least one caregiver being apart from their family for seven days straight, to make sure that patients got to the center, then back in a boat, back to their home. So, it gives you some sense of what they do.
