Okay. Thank you, Jim. Second quarter was a strong one as most of you of have no doubt noted, both in terms of our results and our momentum going forward, both clinically and financially. I'll try to quickly cover 4 topics before turning it over to Luis: Clinical outcomes, government reimbursement, government inquiries and our outlook. First, clinical outcomes, which we always present first because that is what comes first. We are first and foremost a caregiver company, now serving approximately 131,000 patients. With respect to adequacy, which is essentially how well we are doing at removing toxins from our patient's blood, this quarter 97% of our hemodialysis patients had a Kt/V greater than 1.2. Second, with respect to vascular access, 69% of our patients have fistulas, which is the preferred form of vascular access. For these and virtually all other clinical measures, our patient outcomes compare very favorably to national averages. This quality of clinical care not only results in healthier patients but it also drives reductions in hospitalizations and surgical procedures, and therefore, brings significant savings to the United States healthcare system. Second topic, government reimbursement. Luis is going to report on a bunch of the details there but I'll just make 4 contextual comments. A, no doubt, downward pressure will be greater going forward than it has been looking backwards. B, nonetheless, dialysis centers are unusually discrete within the context of the Medicare program, with 87% of our patients being either Medicare or Medicaid and almost all centers being freestanding, which means that if government reimbursement becomes inadequate, centers close. There are virtually no parts of American healthcare where cause and effect is as clear. Point C, with all the pressure on government deficits, there's always the chance that over the next few years, MSP will be extended. And fourth, Point D, is that we have significant hopes that the pressure on government spending and the government deficit will finally get us over the finish line in terms of the government implementing a bigger bundle than currently, where we already have the proven ability to drive quality improvements and total cost savings for our patient population, if they only put in place the architecture for us to do it on a scale basis. Again, Luis will cover some of the government reimbursement details but those are some of the broader perspectives. The third subject, government inquiries. We did learn from the U.S. attorney's office from the District of Colorado that it has opened up a grand jury investigation. I'll make 3 specific comments and then 3 generic ones that you've heard before many times if you've been with us over the years. But the first specific comment is, it is clear that this is very preliminary at this stage. Second, however, we always take these things seriously and we look forward to cooperating with the government. And we mean that, literally, when we say that because we are eager to educate them as to exactly what we have done or not done. And then point 3, it appears there's a lot of overlap with subjects covered, particularly physician relationships, by the old St. Louis investigation, which was started in 2005. They looked into those subjects, spent time with us and it's been quiet for over 2 years. But separate from the specific comments, I'll make 3 generic points and again, I ask the forbearance from those of you that have been with us for a long time. We do thousands of transactions, including hundreds with physicians, and we work very hard to get every one right, technically and in terms of spirit. We are comfortable and confident with our business practices, and these practices regularly go through extensive internal and external review. And finally, none of those words would mean much of anything except our track record of compliance over the last 11.5 years is exceptionally well established and documented. And we did not design the system whereby instead of having discussions, the review process starts with publicly announced investigations, but we've dealt very successfully with that system for 11 highly public and transparent years. Fourth and finally, on our outlook. As our press release indicated, we are raising our 2011 operating income guidance to be between $1.08 billion and $1.12 billion. Importantly, this guidance does exclude the noncash goodwill impairment that we took this quarter. We are also increasing our 2012 OI guidance range. That new guidance for 2012 is $1.2 billion to $1.3 billion. We recognize that this is an unusually positive adjustment to guidance and as always, there is risk we could be wrong. But also as always, our guidance contains the overwhelming majority of probabilistic risk-adjusted outcomes. In addition to the fact that there's some one-time bundling and other adjustments that are going positively for us, our base business, the operations and strategic initiatives are in fact, going well, both in terms of near-term results and momentum. I'll now turn it over to Luis.
