Good evening my name is Chris and I'll be your conference operator today. At this time, I'd like to welcome everyone to the DaVita HealthCare Partners fourth-quarter 2013 conference call. All lines have been placed on mute to prevent any background noise. After the speakers' remarks there will be a question-and-answer session. (Operator Instructions). Mr. Jim Gustafson, you may begin your conference.
Jim Gustafson - VP, IR
Thank you, Chris, and welcome everyone to our fourth-quarter conference call. We appreciate your continued interest in our Company. I am Jim Gustafson, Vice President of Investor Relations, and with me today are Kent Thiry, our CEO; Bob Margolis, CEO of Healthcare Partners; Craig Samitt, President of Healthcare Partners; Garry Menzel, our CFO; Jim Hilger, our Chief Accounting Officer; 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 Quarterly Report on Form 10-Q and Annual Report on Form 10-K. Our forward-looking statements are based on the information currently available to us and we do not intend 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 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. We had solid clinical and operating performance in the fourth quarter. I'll cover four topics: clinical performance, operating performance, an update on our government settlement, and our outlook.
First, clinical outcomes, which we always present first because that is what comes first, we are first and foremost a caregiving company.
On the DaVita kidney care side, we serve approximately 163,000 dialysis patients in America. About one out of every three. On the adequacy front, 98% of our hemo patients had a Kt/V of greater than 1.2.
On vascular access front, 72% of our patients had fistulas, and 2013 was our best year ever in catheter rates, with about 13% of our patients only using catheters.
With respect to clinical metrics for Healthcare Partners, MA plans are benchmarked against national clinical outcome measures from the health care effectiveness data information set, commonly called HEDIS. On the last two quarters, we discussed our 2012 performance in California and Florida. This quarter we'll compare our results in Nevada, our third legacy market, to that national data for Medicare HMO patients.
Our Nevada MA patients once again scored near the top across a wide variety of metrics, including being above the 75th percentile with respect to the percentage of patients screened for colorectal cancer, and the percentage of diabetics with LDL less than 100, and being right underneath 75th percentile at 74 in terms of female patients screened for breast cancer during the measurement period.
So you can see for these clinical outcomes across both kidney care and Healthcare Partners, our outcomes compare very favorably to national averages. And this quality care results not only in healthier patients, but higher patient satisfaction and substantial taxpayer savings.
Next I'll move on to operating performance. Of course, we'll report on the two major components of the enterprise: Kidney Care on the one hand, Healthcare Partners on the other.
Kidney Care 2013 adjusted OI: $1.513 billion, and Healthcare Partners 2013 OI, $385 million. Both of those in line with our most recent guidance for 2013.
Dialysis G&A in the fourth quarter included $8.5 million in dialysis center level impairments. This was required by Medicare re-basing, which requires us to impair certain assets that were no longer -- no longer had any hopes for being profitable.
In addition to this impairment, it looks like we will be closing some centers. As most of you know, we carry quite a few money-losing centers. But there does have to be some limit.
And with the breadth and depth of the Medicare cuts both incurred and contemplated, we simply have no choice in markets where there aren't enough private patients to subsidize the federal government with respect to the Medicare patients.
Next, on to our settlement with the government. As most of you saw today in our press release, we've agreed to a framework for a global resolution with the government. We are pleased to have this framework in place. The final settlement remains subject to negotiating specific terms, but we do anticipate it will be finalized in the coming months as they do.
The final amount is the same as we have talked about the past. In addition we will unwind a limited number of joint ventures and face some other business restrictions. Garry will describe those in more detail in his section, but we repeat: we are pleased to have this framework in marketplace and think you should be as well.
Finally, our outlook. We are updating our 2014 operating income guidance. We now expect Kidney Care OI to be between $1.475 billion and $1.550 billion. This is an increase of $50 million at the bottom end and $10 million at the top end.
The primary driver of this change is the slower rollout of exchanges. And so that will create less rate headwind for us, we think. Over the long-term we still see more downside than upside in the exchanges.
On the HCP front, guidance remains unchanged at $250 million to $310 million. But, we are now more likely to be at the lower end of that guidance range than we are to be in the middle or higher end. The primary driver of that new reality is the New Mexico merger of the Lovelace Blue Cross Shield combination, that that approval by the government has been delayed. And that has a negative effect on our economics.
Our outlook is unchanged in the three HCP legacy geographies. And in general the guidance excludes the potential impact of entering new geographies which, depending on the type and structure of new market entries, could either be a positive contributor or a negative contributor to OI depending on the nature of the beast.
As always, our guidance captures the majority of the probabilistic outcomes, but not all. The actual outcome could be higher or lower.
An additional thought on HCP is that we have had some positive signs in our open enrollment. We're looking at mid to high single-digit growth in our major geographies, which is good news directionally. Although, of course, we need to prove that over the next one or two or three years that we can improve the care of those patients, such that we capture not only the clinical benefits for our patients, but the economic benefits for our shareholders.
I'd like to now turn the mic over to Dr. Bob Margolis.
Bob Margolis - Co-Chairman and CEO, HealthCare Partners, LLC
Thank you, Ken. Good afternoon. I've had just the great honor and privilege to lead HCP for almost 40 years. But as has been previously announced, I'll be stepping down as of March 1, and my role would be handed over to Dr. Craig Samitt.
Craig has been learning, listening hard, orienting, meeting the HCP teammates in all of our markets for close to six months now, and we are now ready to proceed with this planned transition, as I say, on March 1. Craig has an enormous background in both M.D. training and business training, a great commitment to our clinical leadership culture necessary to move HCP to even greater heights.
And I personally look forward to supporting him in my new role as a strategic advisor to the Company, as I remain actively involved especially in growth initiatives as well as remaining co-Chairman of the Board of DaVita HealthCare Partners.
I'll now turn it over to Garry Menzel, our CFO, for more detail on the numbers.
Garry Menzel - CFO
Thank you, Bob. First, some additional comments on our Kidney Care operating metrics. Unacquired growth in the quarter was 5.2% when normalized for days of the week. Kidney Care adjusted operating income was $386 million, which was flat sequentially to the fourth quarter, as US dialysis revenue per treatment, dialysis patient care costs and G&A were all in line with the prior quarter.
During the quarter, we experienced $11 million in international losses, slightly higher than our expectations. As previously communicated, we expect international losses in 2014 to be around $25 million excluding any ramp-up costs for new government tender.
Next, we know some of the questions you no doubt have on the government settlement, so we will now ask and answer them proactively.
Question: what does it mean to unwind a joint venture? Answer: it means that we will have to buy out or sell to our joint venture partner at fair market value. In most cases we would anticipate being the purchaser.
Question: how many joint ventures have we agreed to unwind? Answer: most likely 11 transactions containing 28 centers. Nothing is remarkably different about the size or operations of these centers.
Question: were there any allegations relating to quality of patient care? Answer: No. Question: is our business model reliant on joint ventures? Answer: No, more than 70 percent side of our centers are wholly-owned.
Question: Will we still be able to do joint ventures that are not partial divestitures? Answer: Yes, and we look forward to working collaboratively with the government to ensure we are doing joint ventures in a way in which the government is comfortable.
Next, Healthcare Partners. HCP operating income was also flat sequentially in the fourth quarter at $98 million. For the overall enterprise, our debt expense was $108 million in the fourth quarter. The effective tax rate was 39% in the quarter, although we expect this to be in the range of 40% to 41% for 2014.
I would also like to provide a few reminders as you model the normal seasonality for the first quarter of 2014 in our business.
In Kidney Care the first quarter of 2014 contains three fewer treatment days than this past quarter, so you should expect lower revenue and higher fixed cost per treatment. Also, our payroll tax [count] reset at the beginning of the year, which leads to higher costs of approximately $1.00 to $1.50 per treatment.
At HCP, the severity of the flu season can have a material impact on medical costs.
Finally, turning to cash flow, operating cash flow in the quarter was solid at $354 million. And operating cash flow for the year was particularly strong at $1.77 billion. The strong cash flow in 2013 was due in part to favorable working capital which borrowed from 2014.
We have initiated operating cash flow guidance for 2014. This coming year we expect operating cash flow to be between $1.45 billion and $1.55 billion, excluding any payment associated with the government settlement.
With that, operator, let's go ahead and open it up for Q&A.
Operator
(Operator Instructions) Matthew Borsch, Goldman Sachs.
Unidentified Participant
This is [Brian] on for Matt. I just had a question on HCP and I was wondering how you were positioning yourself with payers to handle the potential rate update in a week and a half.
Craig Samitt - President, HealthCare Partners, LLC
This is Craig Samitt, afternoon everyone. We are certainly waiting for feedback from the government regarding the impact of rates in 2015. As we discussed in December, we've been renegotiating contract terms that provide us greater protections and inputs in plan design. We've renegotiated the contract with a large payer-partner in one of our legacy markets that provides us new protections in three dimensions.
First, in the event that benefits are increased, revenue to HCP will be increased by an independently determined value of the enhanced benefit. Second, in the event that benefits are decreased, we and the payer will seek to mutually agree on any reductions of revenue to HCP.
Third, in the event that there is a material change in CMS funding or funding structure, HCP will have a 90-day notice period to drive a renegotiation of the revenue terms with the payer prior to arbitration. The third scenario is more in line with the circumstance that we faced in 2014 in terms of rates and benefit preservation. And so this is where we find our efforts in renegotiating contract terms with payers going into 2015.
Kent Thiry - Co-Chairman and CEO
Let me hasten to add that is an example of the type of work we will do going forward. We still have a number of legacy contracts that do not have those provisions. And exactly what we do, and what the payers do, if and when there are additional rate cuts is unclear and will be determined out in the marketplace.
Unidentified Participant
Okay great. Just looking at sort of the 2014 HCP guidance, and you mentioned how it will tend to be towards the lower end, is that based off of uncertainty around the 2014 preliminary rates? Or have you sort of seen -- sort of have a view into 2014 as to what's driving that?
Garry Menzel - CFO
No, [Brian]. The change in our perspective on 2014 is almost entirely driven by the fact that the FTC has been slow in approving the merger of two plans in that market. And some of our new contractual provisions are not triggered until that deal is consummated. That's why there is the adjustment in our thoughts on 2014.
Unidentified Participant
Okay great, thank you.
Kent Thiry - Co-Chairman and CEO
All right thank you, Brian.
Operator
Darren Lehrich, Deutsche Bank.
Darren Lehrich - Analyst
Thanks, good afternoon everybody; just a few things here. First, just given that you received the restricted Knox-Keene license status from California, should we expect to see some of your California business get recorded as full risk on the P&L this year?
Kent Thiry - Co-Chairman and CEO
The short answer is yes, but moving things over -- moving the contracts over takes time. So we can't give you a specific schedule. But over time some of that will happen. Is that right Jim?
Jim Gustafson - VP, IR
That's right. And Darren, the net is that there won't be a bottom-line impact. It is simply a revenue impact of moving from a net to gross booking for some of that revenue.
Darren Lehrich - Analyst
Okay, but didn't you share in the risk with other parties such that when you take full risk, the economics might over time be different? Just want to clarify that, Jim.
Kent Thiry - Co-Chairman and CEO
No, there's no change because we've always managed comprehensive populations in a comprehensive way. All that's changing here is how it gets accounted for.
Darren Lehrich - Analyst
Great, okay; that's helpful. And then I wanted to also just ask about the duals opportunity. And you've discussed a lot; we are starting to see a little bit more in terms of development around planned announcements.
Do you still see your plan relationships and market share as positioning you well in California around the duals? And anything to add just based on some of this recent activity?
Bob Margolis - Co-Chairman and CEO, HealthCare Partners, LLC
It's a moving target, as you probably know, if you've been following the releases. L.A. County, which is the biggest opportunity as far as numbers and dual, has now announced the addition of three new plans. We have excellent relationships with those two, not with CareMore.
The revenue associated with the duals has not been formalized. And so everybody continues to look at it as an opportunity, if the revenue matches the risk. But at this point, it's hard to predict that.
Darren Lehrich - Analyst
Okay. And just based on what you're hearing about plan pricing, do you think it will be good enough to manage the populations effectively?
Bob Margolis - Co-Chairman and CEO, HealthCare Partners, LLC
We hope so. And we're certainly in active discussions with all of the relevant health plans. You may have also noted that in Orange County they delayed the rollout of the duals. So this will be an L.A. County-specific issue with those several plans that were announced.
Darren Lehrich - Analyst
Great, okay, thanks for that.
Operator
Justin Lake, JPMorgan.
Justin Lake - Analyst
First question, just wanted to follow up on the Medicare advantage commentary. I appreciate all the detail. What -- as you kind of think about a target for -- if it's going from 2015 in June, Craig, what is your target there in terms of these new contractual rates? What percentage of members would be on those arrangements in a reasonable view?
Craig Samitt - President, HealthCare Partners, LLC
Well, in terms of the renegotiation of the contracts that KT and I have referenced?
Justin Lake - Analyst
Yes.
Craig Samitt - President, HealthCare Partners, LLC
Right now, the negotiated contract that I referenced represents a minor subset of our overall MA population. And we will grow from there over the course of the coming years as we renegotiate the contracts.
Justin Lake - Analyst
Okay. Is there a number that in terms of -- is 20% of members reasonable to think of on these types of contracts going into 2015, or is it just too early?
Kent Thiry - Co-Chairman and CEO
I think this is a little bit like, as we move to bundling and the Kidney Care side, Justin, where I don't think it's in your best interest for us to provide quarterly updates on what percent of the contracted book falls into what categories. So, suffice it to say, we're working the issue as we pledged to you we would. And I think you'll just have to accept the fact that it's incorporated into our guidance beyond that, at least for now.
Justin Lake - Analyst
Okay. And on the economic side, clearly these are going to be a mitigator to some of the headwind. Any way to think about how much, though, relative to the headwind you're facing in 2014 when you didn't have these?
Kent Thiry - Co-Chairman and CEO
Say the question again, please, Justin.
Justin Lake - Analyst
Sure. So if I do some back of the envelope math, it looks like you've got a few hundred basis point headwind in Medicare Advantage margins in Healthcare Partners this year, given the rate environment. So if we just kind of look out to 2015 and say, okay, that rate environment is going to be similar, how much would the margins -- how much better would the margins look under these types of contracts?
Just trying to understand in terms of how much you think the offset would be. Do you think the margins would be flat in these types of contracts and you would get to a reasonable outcome, or down less, but still down?
Kent Thiry - Co-Chairman and CEO
It's a fair question and we are not prepared to answer that right now. So let us just play with that, Justin, and see if that's something we want to be talking about so publicly next quarter. And it won't be in the end, of course, an analytically precise number because of some of the specific variables in some of the contracts.
But I hear what you're saying that with -- if we had more of what we have now with respect to that contract, how much would that mitigate. I hear the question, and right now it's in a minority of contracts, and so you can take that as a directional answer. And beyond that, let's wait until next quarter.
Justin Lake - Analyst
Okay and then just a couple quickies. One, on the exchanges, you talked about that being less of a headwind because there is less membership there, totally understandable. But have you seen any evidence of the membership that is on the exchanges yet having an impact on rates or where -- or the choice of dialysis center for these patients in these exchange products?
Kent Thiry - Co-Chairman and CEO
As to rates, we know that we have only agreed to our normal commercial rates with respect to any exchanges. At least I don't know of any exceptions to that, and so if there are any, it would be very minor. But it could be literally zero.
We know of other people who make the same statements. We don't know where some of these patients are going to be taking care of, as some of these narrow networks do not have quality dialysis providers in them. And we have not noticed any material outflow of patients from our centers.
But it's so early in the year and we don't get get data from every center right away. And so I think we have to wait a couple more months before we can comment more analytically on your question.
Justin Lake - Analyst
Okay, great. Thanks.
Operator
Kevin Fischbeck, Bank of America.
Kevin Fischbeck - Analyst
I was wondering if you just had a sense of where your physician competitors are operating from a margin perspective, either when you do due diligence on potential acquisition or just industry kind of information and how you think about HCP's margin and how they stack up versus the peers?
Kent Thiry - Co-Chairman and CEO
I think we have limited insight into a lot of the other groups out there. So it would be a pretty speculative answer, and I think therefore probably not that valuable to you. I don't know, Bob, can you offer anything more definitive than that?
Bob Margolis - Co-Chairman and CEO, HealthCare Partners, LLC
I think that's a complete answer. We do a lot of M&A due diligence and many groups are struggling, especially with the MA cut. And it's an opportunity for us when it comes to consolidation and growth.
Kevin Fischbeck - Analyst
Yes, and that kind of gets to the point of my question. I guess when we normally evaluate a health care provider, we kind of say, well, what are the industry margins? Where can Medicare rates go from a floor perspective, because they can't go to a point where they push a large sum of the providers into real crisis mode.
And so I was just trying to get a sense of whether the peer margins -- because the way I understand how you thought about 2014, originally your thought was MCO's won't be able to -- will cut benefits rather than pass the cuts onto you. And then as the year went on you realized that they were not cutting benefits, and that since your peers were taking the rate cut pass-through to them, you kind of had to follow suit.
I was just wondering whether were getting to a point in 2015 where the peer margins are getting to a point where they really can't afford to take another rate cut the size that they took this year, and that maybe your margins were better than the peers and that was going to be a sustainable point. I don't if you have any sense of that.
It sounds like to some degree you see that happening now. At least some of your competitors that you are evaluating as far as deals go are reaching that point. I just wasn't sure if you had a sense of where we are in that cycle.
Bob Margolis - Co-Chairman and CEO, HealthCare Partners, LLC
Clearly last year we thought that the health plans would trade some growth for margin. They didn't. There's a lot of belief that they may this year, but I don't think we're ready to speculate based on our experience last year. But there's no question that the pressure on physician groups with the revenue cuts is, in some cases, going to put them in a position where they have to do something to survive.
Kevin Fischbeck - Analyst
Okay. And then the protections that you mentioned in that one contract, that's very helpful. Are these protections that you found to be somewhat standard from other practices and you're playing catch-up to that? Or are you kind of leading the way in trying to get these things to become more standard with industry practice?
Bob Margolis - Co-Chairman and CEO, HealthCare Partners, LLC
One thing you can say about us is we learn, and so we are leading the way in what we believe is an unusual rate environment. Recognize that the last couple of years of parity and RAF rescaling is a new environment compared to the many years ahead or before that. So this kind of issue was not raised frequently in contract discussions. I'd say we are smarter now than we were a year ago and we're making good progress.
Kevin Fischbeck - Analyst
Okay and then last question for me. Just going back to the other question about the Knox-Keene license, if that doesn't really help your profitability overall, what was the strategic rationale for getting a license?
Kent Thiry - Co-Chairman and CEO
From a -- just working with the government point of view that enough government folks preferred us to take that path, and in general we like to work as collaboratively as possible with all government agencies. And so that was the primary motivator.
Kevin Fischbeck - Analyst
It's not like a step toward integrated care or ACOs or anything else like that. It was just kind of you continue doing what you've always been doing?
Kent Thiry - Co-Chairman and CEO
I think on a secondary basis, it does in some cases create some more flexibility for doing different types of business. Although, in all of those cases, we could have entered into shared savings relationships of the same type that we had in Southern California before we did the Knox-Keene. So it was not essential, but it will make some of those other things easier. Are those words you would use too, Bob?
Bob Margolis - Co-Chairman and CEO, HealthCare Partners, LLC
Yes, I think that will give us greater flexibility.
Kevin Fischbeck - Analyst
Okay, great, thank you.
Operator
Kevin Ellich, Piper Jaffray.
Kevin Ellich - Analyst
First on HCP, Kent, I was wondering if you give us an update on your outlook for acquisitions, I guess dependent upon how the rates look when they come out for 2015. Do you think that's going to accelerate the pace of deals that you'll get done?
Kent Thiry - Co-Chairman and CEO
It's a fair question, Kevin. But you know as well as we do it is so hard to predict what deals are going to come out, and with what pricing expectations and what your competitors are going to do.
So, it is logical to think that there might be some increase in M&A activity because of the squeeze going on economically. But boy, there are so many variables that I would be real hesitant to throw anything into a model.
Kevin Ellich - Analyst
Sure. And then does the settlement that -- the $389 million that you guys have reserved, does that change how much you're willing to spend on deals in the next one to two years, or I guess how does that play into the equation?
Kent Thiry - Co-Chairman and CEO
The short answer is no. The types of joint ventures that are the focus of the settlement with the government are not a material part of our past, nor our future, and not a big part of the industry overall. And so it really has no impact on our or anybody else's acquisition thinking, would be my guess.
Kevin Ellich - Analyst
Got it. You said that you'll unwind 11 JVs. How many will you have remaining after you unwind those?
Kent Thiry - Co-Chairman and CEO
I don't think we've ever disclosed that publicly, but suffice it to say it's a small percentage.
Kevin Ellich - Analyst
Got it. Okay, and then last question on the dialysis side, just wondering if -- looking at your cost structure from supplies and other expenses, is there anything in the next one to two years that you can call out or you think help us out with that could help you reduce that?
Kent Thiry - Co-Chairman and CEO
I would just say on both sides of the house, when reimbursement gets cut, you've got to look for savings. And the notion of finding zero just doesn't feel like a high-performing organization.
And so while we, on both sides of the house, feel quite good about our economic prudence in the past, we will be looking at everything again with a fresh perspective that's forced by reimbursement cuts. But there's nothing -- there's no big straightforward lever to pull that we've been just sitting around not pulling before.
Kevin Ellich - Analyst
Got it, thank you.
Operator
Gary Lieberman, Wells Fargo.
Gary Lieberman - Analyst
If I could follow up on that last comment, Kent, about the cost-containment, how do you feel -- HCP has talked about some of what you would be doing in the face of the rate cuts to try to cut costs? And how would you characterize where you are in that process?
Kent Thiry - Co-Chairman and CEO
I think the answer would be disappointing. We don't have anything dramatic to say. We haven't had any stunning insights and the numbers that we have come up with are incorporated into our guidance. And beyond that, nothing noteworthy enough to mention. Am I answering the question or did I blow it?
Gary Lieberman - Analyst
No, I think that's an answer. Maybe another question. You mentioned closing of some dialysis centers. Could you give us any kind of data, either number of centers or amount of revenue or EBITDA impact?
Kent Thiry - Co-Chairman and CEO
We haven't decided yet, and as you might guess, and as many of you know, for us, an incredibly painful decision. There's a reason we carry a lot of money-losing centers, not counting de novo centers which, of course, you expect to lose money for a while.
And that is that we are as successful enterprise. We love taking care of our patients. And the notion of closing centers where we are taking care of people is just not what we're about.
At the same time there have to be limits. And if the government is going to cut rates as they have and as they are contemplating, doing nothing is just not appropriate, although anything we would do would always be in careful collaboration with other people in the local market in order to maintain continuity of care.
So we can't give a number right now because we haven't decided and we are agonizing as we look. But we felt it was important to let you know that the number wasn't going to be zero.
Gary Lieberman - Analyst
Would it be reasonable to assume there would not be much EBITDA impact, if any?
Kent Thiry - Co-Chairman and CEO
Correct.
Gary Lieberman - Analyst
Okay, and then maybe my final question, in terms of unwinding some of the joint ventures, does that potentially have any impact on the medical directors at those centers? Or how do you manage that?
Kent Thiry - Co-Chairman and CEO
Could you ask that question again, please?
Gary Lieberman - Analyst
As you unwind some of the joint ventures, could that potentially impact any of the medical directors that you have at the centers, and so, could it be any kind of operational issue for you?
Kent Thiry - Co-Chairman and CEO
I appreciate it. Short answer is, yes, it could, but it's unlikely. Most of the relevant transactions were with groups with whom we have larger and multifaceted relationships, and therefore not expected to change.
And even in a couple of cases where that might be a smaller relationship, in most of those instances, it shouldn't make a difference either. As someone mentioned earlier, over 70% of our centers already are wholly-owned. So it's not that us owning 100% of something is somehow a de-stabilizing element for the most part. Of course there could be an exception or two, but not the rule.
Gary Lieberman - Analyst
Okay, that does it for me, thanks a lot.
Operator
Frank Morgan, RBC Capital Markets.
Frank Morgan - Analyst
Good afternoon. On the subject of those JVs, could you describe to us exactly what is the characteristic of these JVs that you're having to unwind? What is it the government doesn't like versus the other JVs you have where there's no problem?
Kent Thiry - Co-Chairman and CEO
Let me first go backwards a moment, because someone asked a few moments ago how many JVs we have. And that's not something we have disclosed before. But we have disclosed the percent of our revenue that comes from JVs, and that's right in the ballpark of 21%. So, from that, you can pretty well in fair how many there are out there and be in the right strategic ballpark.
The type of JV that we are focused on are JVs where we did a partial divestiture, which is to say we owned 100% and then sold a percentage of that, a minority percentage of that 100% to local nephrologists.
Frank Morgan - Analyst
Versus your other ones you just -- these are new partnerships, and so it's just that simple?
Kent Thiry - Co-Chairman and CEO
It's pretty much that simple. And because we are in the process of finalizing all aspects of the agreement, I just don't think it's a good idea to start parsing things any further. So, I think we'll leave it at that for today.
Frank Morgan - Analyst
Okay, that's fair. In terms of the kidney side of the business, operating income guidance going up here, would you characterize that more as topline driven? Or is this more something you are doing on the expense side?
Kent Thiry - Co-Chairman and CEO
It's more topline driven because of the lower enrollment in the exchanges.
Frank Morgan - Analyst
Okay, so more a function of pricing. And then in terms of external growth, obviously you did a few acquisitions this year in the US and internationally, as well as some de novos. What are you embedding in your guidance for 2014 on the subject of either de novos or acquisitions?
Kent Thiry - Co-Chairman and CEO
I don't think we have broken that out. Suffice it to say we anticipate doing more acquisitions. Whether it will be a little more or a little less than the prior-year, it's impossible to predict.
Could there be a significant drop off and acquisitions? Maybe. Just don't know, too early in the year. Would there be a significant increase acquisitions on the Kidney Care side? That's unlikely. There's nothing out there that would provoke that.
On the de novo front we once again expect to have a robust year of building de novos in areas where there's enough profit patients to subsidize the federal government. But we don't go beyond that and give a specific number. It's always a little hard to nail down.
Frank Morgan - Analyst
That's fair. And last one and I'll hop. The operating income being up nicely, your cash flow from ops down, you highlighted the one item on just timing of working capital. Is there anything else that would cause that disparity? Thanks.
Kent Thiry - Co-Chairman and CEO
The change in working capital was one of the major drivers. Was anything else noteworthy that we should mention Jim or Jim?
Jim Hilger - CAO
This is Jim Hilger. We've had some tax preference items in 2013 that won't be reported or repeated in 2014, accelerated depreciation being the most notable one.

First, let's get back to exchanges. How many exchanges have you guys decided to participate in, versus not participate? And kind of what drove that decision? Was it pricing or was it something else?
Kent Thiry - Co-Chairman and CEO
I don't know the number and I don't know that we've tracked because, in general, any exchange that's willing to pay our normal commercial rates we sign up for. And those that don't, we don't. So it's been a pretty simple decision filter and I don't know that anybody has added them up.
Margaret Kaczor - Analyst
Do you know if they want to actually accept kind of the lower rate contracts or any of the private guys or kind of these smaller guys?
Kent Thiry - Co-Chairman and CEO
I'm sure that some people have and we have no way of knowing how many. But given we are all in the same situation where the 10% of our patients that are private subsidize the 90% that are government, there are limits to how much of that you can do before you put your entire survival at risk. So I'm sure the answer is yes, and only time will tell how many it was.
Margaret Kaczor - Analyst
Okay. And then could you guys talk a little bit more about HCP acquisition targets? In the past you kind of talked about kind of the two- to three-year time horizon as the results start to materialize. Is that still accurate?
And then also can you talk about the acquisition candidates that you've done diligence on? How many was that? Why wouldn't things pan out there? Or is it just you guys are overloaded right now in the queue with people interested in getting acquired?
Kent Thiry - Co-Chairman and CEO
Let me take a quick stab and we'll see if either Craig or Bob want to amend. With respect organic growth in patient numbers, that's where there's a time lag as we work to familiarize ourselves with the patient's condition and provide coordinated care. And as we succeed in doing so, bringing down the cost of that care through better health. So that's one of the references to the two- and three-year time frame that you mentioned.
When we buy something, if in fact it has a mature Medicare Advantage population that it's been working with, then there could be profits immediately. And of course we would be paying on a multiple for that.
And then, as to the pipeline of M&A opportunities, it is -- there is one. It is so impossible to predict with any accuracy which organizations will, in fact, decide to sell and whether or not we'll be the winning bidder, that helping you do a better job of forecasting is unfortunately not something we're able to do.
And we've also mentioned in the past how we had to build the business development capability pretty much from scratch, with respect to new markets, that we were necessarily going to be a little awkward and slow in the early going. And we are making some good progress but that certainly has slowed us down. Have I covered it, Margaret?
Margaret Kaczor - Analyst
Yes. So I guess the acquisitions that maybe did or did not pan out, it doesn't sound like that was a big number maybe. But those that maybe didn't have a higher price premium than you guys were willing to pay, did those go to hospitals largely or what other players -- insurers?
Kent Thiry - Co-Chairman and CEO
Of the ones we lost that are of size, I could think of a couple; maybe three. Two went to payers and one went to a health system, a hospital health system. And that -- I worry that that n is so small it could be misleading, but it is the factual answer to your question of the three that I can think of offhand.
Margaret Kaczor - Analyst
Great, thank you.

Lisa Clive - Analyst
Three questions; first, on the dialysis business, integrated care obviously the rate cuts slowed down the progress of the development of the ESCO program and potentially changed the decision around participating. Can you give us an update on where you stand with Medicare on this? And can you give us any insight into how Medicare is thinking about the size and duration of the program?
And then second question, if a new ESA enters the market this year, is it safe to assume, given that you signed a pretty long-term contract with Amgen that that allows for some sort of automatic price stepdown? And how should we think about the potential impact on your cost structure from any changes in the ESA competitive landscape?
Kent Thiry - Co-Chairman and CEO
On ESCOs, we do not know when CMS will come out with the version 2, or version 3 depending on how you are counting. And we still have high hopes because we know they want to do it. And we know that we and other providers can improve quality significantly and dramatically and transparently, while at the same time saving literally billions of dollars. So we're incredibly enthusiastic about it, but just don't know when the next version will come out.
The good news is that there's more and more recognition of the fact that this type of integrated care is the answer.
And then on ESAs, I have to admit I did not get a refresher on the stipulations in our contract as to what we can disclose and what we cannot. And so, on any kind of auto step down in price and the other issues you mentioned, we just, I think, are not allowed to disclose.
Lisa Clive - Analyst
Okay, fair enough. And a final question, given the Medicare rate cut that went through, spread out over four years, are you seeing any increase in activity with small providers who are interested in selling themselves given the headwinds they are facing now?
Kent Thiry - Co-Chairman and CEO
Not anything significant yet.
Lisa Clive - Analyst
Okay, thanks.

Gary Taylor, Citigroup.
Gary Taylor - Analyst
I had a couple of questions. But I guess I wanted to come back to this ESA question, because I thought, Kent, you had publicly pretty firmly said before that there was no automatic sort of price step down in the long-term contract with Amgen.
Kent Thiry - Co-Chairman and CEO
If I said it before, then it was true and it's still true. But I just couldn't remember offhand the terms of the contract and what we have been allowed to disclose or not. We just didn't do a refresher on that one leading into this call. And so we had to err on the side of being safe. But if it was disclosed before, it must have been true and if it was true, it still is true.
Gary Taylor - Analyst
Okay. On HCP, the duals in California that we were talking about earlier, is there anything explicitly in the 2014 guidance in terms of revenue or operating income contribution in 2014?
Kent Thiry - Co-Chairman and CEO
The answer is no, is zero.
Gary Taylor - Analyst
Okay and which -- there was a quick discussion, kind of, of where the rates are shaking out and so forth. Is that a program where strategically you'd be willing to absorb losses initially to be involved in the rollout of that program?
Kent Thiry - Co-Chairman and CEO
Only if we thought the program was stable enough and long-term enough that we could get our shareholders a return on the capital that we were investing. What is so often the case is that if you take that risk upfront and succeed right at the point that you might be expecting to earn the fruits of your labor, the rules change. And therefore you're not allowed the return that you invested to get. So you've got to be awfully cautious on that sort of thing, and therefore, can't answer with a definitive yes or no.
Gary Taylor - Analyst
Okay, last question. At the investor day, Kent, I believe you said if you saw a similar Medicare Advantage cut in 2015, HCP's operating income would be down, or you might've said likely would be down again, I believe. Is there enough happening in terms of these renegotiated MA contracts that you talked about a little bit today that you'd want to revise that outlook? Or would you still stick to that?
Kent Thiry - Co-Chairman and CEO
I absolutely would stick to what was said at the capital markets, that if we get hit with the rate decreases, OI will be down.
Gary Taylor - Analyst
Okay, all right, thank you.

Whit Mayo - Analyst
Just had a couple of quick ones. You have referenced 2014 being an investment year for HCP I think on this call and also at the capital markets day. And I think I heard you referenced business development earlier as an area you are particularly focused on now. But is there anything specifically to call out at this point in time, in terms of systems or other capabilities that you've identified as a priority going forward?
Craig Samitt - President, HealthCare Partners, LLC
This is Craig again. Our primary focus for investment thus far in 2014 has been in the business development and integration arena. So we've added resources with the business development team.
We're leveraging our legacy Healthcare Partners and DaVita expertise in existing and new markets. And we are laying the groundwork for a successful post-acquisition integration. So that's where a majority of our resources are thus far.
In terms of your question about other systems and processes, I would say that we are in the evaluation phase of each of those to determine if additional investments should be made, and technologies or processes that would further enhance our capabilities in the future. Does that answer your question?
Whit Mayo - Analyst
It does, but can you be maybe a little bit more specific about what those capabilities are? Is it actuarial capabilities? I didn't know if you'd be willing to comment a little bit further.
Craig Samitt - President, HealthCare Partners, LLC
There are no particular capabilities that I would call out at this point. I think we're looking at broad-based opportunities for improvement.
Whit Mayo - Analyst
Okay. And my last question just relates to buybacks. You hit the pause button on that a while ago, and it might just be helpful to hear your latest thoughts on where the internal discussion is around rethinking share repurchase at this point. Thanks.
Kent Thiry - Co-Chairman and CEO
Yes, our thinking on share buybacks and just in general capital deployment is as robust as ever. And over the last 14 years, as some of you can attest, we have been active along the entire spectrum of having a higher leverage ratio, having a lower leverage ratio, doing a lot of buybacks, doing no buybacks; spending a lot of money on acquisitions, spending no money on acquisitions. And so we look at that full spectrum every single quarter.
And of course with respect to share buybacks, we look at what our alternative uses of capital are, what our current valuation is. What are the risks dynamics as you look out in the near and intermediate term? And so we play with it all the time and right now we don't have anything interesting to say about any conclusions in that realm.
Whit Mayo - Analyst
Okay, thanks a lot.
