Thank you, Javier. I will start with an overview of the financial results for the Kidney Care business as reflected in our continuing operations. Adjusted operating income for the fourth quarter plus $430 million, up approximately $26 million or 6% versus the third quarter, although, the fourth quarter benefited from a couple of items that are outside our run rate. First, we've recognized $14 million shared savings revenue that our DaVita Health Solutions business earned throughout 2017. Second, we had $9 million onetime benefit in insurance expenses due to revaluation our reserves. As a reminder, adjusted operating income for the third quarter was $404 million, but this figure was negatively impacted by approximately $14 million due to the hurricane season. The fourth quarter was shorter by one-half treatment day relative to the third quarter, which accounts for most of this difference. For our U.S. dialysis and lab business, our reported revenue per treatment net of provision for bad debt was up $0.49 per treatment quarter-over-quarter. Underlying this are two largely offsetting unusual items. First, we've recognized approximately $20 million in cash receipts that we have previously reserved that flow through the gross revenue line. This was offset by $23 million increase in our provision for bad debts to address our higher estimates of patient pay receivable write-offs for all of 2017. To comply with the new revenue accounting standard, starting with the first quarter of 2018, you'll start to see a few changes and additions to our disclosures. I want to highlight two in particular. First, we will only be reporting revenue per treatment net of provision for bad debt. Second, we expect to recognize the benefit of approximately $30 million in the first four months of 2018 from a change and how we account for Medicare bad debt recoveries. Prior to 2018, we've recognized these recoveries only after attempting to collect, which takes approximately four months. Under the new rules, we will estimate and recognize estimated Medicare bad debt recoveries at the time of treatment. I refer you to our Form 10-K to be filed later this month for additional details. Our patient care costs were down approximately a $0.11 per treatment quarter-over-quarter. As a reminder, our patient care cost in the third quarter of 2017 was higher by approximately $1 per treatment due to the hurricane impact. U.S. dialysis and lab segment G&A costs were down approximately $1.69 per treatment sequentially due to lower outside professional fee expense and normal quarterly fluctuations. For fiscal 2017, G&A was approximately 3% per treatment - was down approximately 3% per treatment year-on-year. As G&A always had some quarterly variability, the annual G&A per treatment is a better result to use for your go-forward modeling. Lastly, please keep in mind that our first quarter tends to be the weakest quarter of the each year due to seasonality with two fewer treatment days in Q4 flu impacts and higher payroll taxes. A few words on the DMG sale, as a reminder we announced in December that we entered into an agreement to sell DaVita Medical Group to Optum. We are working with Optum on required regulatory approvals and continue to target closing in 2018. It has been a very productive working relationship and we look forward post close to the additional long-term benefit that the business will get from our relationship with Optum and United. Because of the pending transaction, the DMG business has been reclassified as held for sale and the results of operations are reported as discontinued operations. In addition, prior period presentations have been revised to conform to current year presentation. In the fourth quarter, DMG generated operating loss of $23 million. This includes operating results, which were negatively impacted by a bad flu season and both direct and indirect financial impact from the transaction, including the shift to held for sale accounting. In addition, we recognized the tax benefit of $164 million in order to recognize deferred tax assets require upon the classification of DMG as held for sale. The net impact of all these items is that we reported $144 million gain as one line on the income statement as discontinued operation. On to international, our strategy is evolving under the direction of the new leadership, the result has an increased focus on core markets, where we are well positioned to achieve scale and drive clinical and financial value. Also, as we discussed last quarter, we restructured our international organization to streamline our reporting structure and reduce administrative cost, and anticipate this will save $6.5 million in annual G&A expense in 2018. As a result of these strategic changes, including changes in expectations concerning the JVs available market opportunities. We are taking a non-cash write-down of our investment in the Asia Pacific JV up $280 million, which reverse is much of the $381 million non-cash gain we booked in 2016 and 2017 from the creation of this joint venture. Adjusted operating losses from our international business was $46 million for fiscal year 2017, which included $2 million in impairment charges, $4 million in prior period adjustments and $8 million in foreign currency losses. This was in line with revised guidance that we had provide - previously provided for 2017. As we have discussed in recent quarter, we expect to achieve breakeven operating income in late 2018. This is incorporated in our enterprise guidance for continuing operations for 2018. Next some information on taxes, to account for the impact of U.S. tax reform legislation passed in December, we've recognized one-time reduction of tax expense of $252 million in the quarter. This is the net gain to remeasured our deferred assets and liabilities to reflect our expected go forward tax rate. Excluding this and other one-time items, our adjusted effective tax rate on continuing operations was 40.4% in the quarter and 39.1% for 2017. As we continue to review the impact of the recently announced tax reform, we now expect our effective tax rate from continuing operations in 2018 to be 26.5% to 27.5%. Despite moving up to bottom end of the range by 50 basis points, we continue to expect 2018 income tax expense reduction of $110 million to $130 million from tax reform. Now cash flow, enterprise operating cash flow for 2017 was $1.907 billion, within our previously provided guidance. For 2018, we will provide cash flow guidance for continuing operations in light of our expectation that the DMG sale will close this year. We expect operating cash flow from continuing operations to be $1.4 billion to $1.6 billion. This guidance reflects the benefit of tax reform from both the lower effective tax rate and the accelerated depreciation of certain capital expenditures. This cash flow guidance excludes any cash flows from DaVita Medical Group, although investors should keep in mind that we will still own the cash flows from this business, up until the date the transaction closes. In 2018, we expect to spend $925 million in CapEx on continuing operations, roughly evenly split across maintenance and development CapEx. This is an increase of approximately $100 million from 2017. But most of this increase is due to expenditures we do not expect to recur in 2019. So holding all else equal, we expect our CapEx in 2019 to be closer to our 2017 levels. For the full year 2017, we repurchased 13 million shares of our common stock or nearly 7% of our shares outstanding at the beginning of the year. During Q4 2017, we re-purchased 7.4 million shares. We have also repurchased approximately 900,000 shares this year through February 12, 2018. Now, I'll turn it over Kent for some closing remarks.
