Stephen J. Hemsley - Chief Executive Officer & Director: Thank you and good morning. Thank you for joining us today to review our results for first quarter 2016. UnitedHealth Group businesses have steadily strengthened over the last several years and this trend continued in the first quarter of 2016. Our momentum is evident in the highest levels of customer and consumer retention in our history combined with new customer acquisitions driving strong revenue gains across the enterprise; growth in the size, scope and diversity of products and services within our client base as well as a number of new customer opportunities we are pursuing; steadily improving metrics for brand and reputation and steadily rising net promoter scores across our businesses. Customers buy value and expect results and we are sharpening our performance focus, driving the highest quality customer experiences, helping us become the go-to choice, a must-have partner for everyone looking to improve performance and sustainability in health benefits and health services. When we combine higher quality from consistent excellent execution with practical innovations at scale, our opportunities to grow and serve continue to expand. Our intensified commitments to quality performance and to growth on the strength of that quality positions UnitedHealth Group to look forward toward what we believe may become our best decade of performance and growth yet. Turning to the results, we are reporting today our first quarter revenues grew 9% prior to acquisitions and over 24% overall to $44.5 billion with broad strength across the enterprise. In health benefits, medical costs were well managed and controlled as is evident in the consolidated care ratio of 81.7%. Prior-year reserves developed favorably by $360 million in the quarter; the medical days claims payable increased four days year over year to 51 days. Cash flows of $2.3 billion or 1.4 times net income continued at a strong and reliable pace. First quarter's operating cost ratio decreased 110 basis points year over year to 15.2% due to a combination of business mix, technology-driven operational efficiencies and the cumulative overall effects of revenue growth. These efficiency gains were partially offset by continued investments in our businesses. Our tax rate reflected early adoption of the new accounting standard for stock-based compensation, adding roughly $0.06 per share in the quarter. You should expect it will add considerably less in coming quarters due to the natural pattern of equity-based compensation activity for our company. First quarter adjusted earnings of $1.81 per share grew 17% year over year and our full-year revenue and per-share earnings outlook is strengthening, as Dave Wichmann will describe shortly. Since we know exchanges are in the minds of many of you, let me take a quick minute for an update. As you know, we have been evaluating public exchanges on a state-by-state basis. We have maintained our regular public dialog with you since November about the individual exchange market and how our own experience and performance have been unfavorable in these markets. The smaller overall market size and shorter-term higher risk profile within this market segment continue to suggest we cannot broadly serve it on an effective and sustained basis. Next year we will remain in only a handful of states, and we will not carry financial exposure from exchanges into 2017. We continue to remain an advocate for more stable and sustainable approaches to serving this market and those who rely on it for care. With that, I will now ask Larry Renfro to review Optum's exceptional performance and then Dave to cover UnitedHealthcare and provide UnitedHealth Group comments. Larry?
Larry C. Renfro - Chief Executive Officer-Optum & Vice Chairman: Thanks, Steve. Optum is off to a strong start again this year, consistent with the ambitious plans we shared with you at our Investor Conference last December. Optum will again grow revenue at more than 20% and earnings from operations at above 30% this year. We continue to estimate Optum will contribute 42% or more of enterprise-wide operating earnings this year, even considering our ongoing investments to support the future growth of this young business. Optum's performance reflects the large-scale opportunities we are pursuing and the tremendous efforts our 100,000 employees make to deliver differentiated services and capabilities to those seeking to solve complex challenges across the healthcare system. Our first quarter revenues of $19.7 billion grew 54% year over year or 11% prior to acquisitions. OptumRx revenues grew 72% to $14.3 billion, while OptumHealth and OptumInsight together grew revenues to $5.7 billion, which is growth of 21% over the first quarter of 2015. Our first quarter operating margin of 5.6% includes the continuing increase of pharmacy care revenues as you have seen in the past two quarters. Overall, Optum produced $1.1 billion in earnings from operations. As you may know, we identified five drivers for Optum's growth over the next five years. They are pharmacy care services, care delivery, technology, government services, and international. Last quarter we spent some time on a more detailed review of care delivery. Today we will focus on pharmacy care services then follow up briefly with data analytics. Pharmacy care services is a high priority area for us. This focus goes back from 5 years to the original decision to undertake the largest and arguably most complex business in-sourcing ever attempted. It required significant investments, precise execution and flawless delivery. As you know now, it has been a real success. Last year we took another step, our combination with Catamaran led by Mark Thierer who now heads our entire OptumRx platform and serves as a senior member of our overall Optum leadership team. This combination was a significant advance of scale and today the business is running at over 1 billion scripts annually up from 350 million in 2012. Eight months in, the greatly expanded OptumRx is advancing a meaningful differentiated solution for clients in the marketplace with distinctive capabilities around patient centered data analytics, new capabilities in specialty pharma such as home infusion and workplace related resources. Since we came together our retention rates have persisted in the high 90%s and we are building our largest ever pipeline of opportunities. We were pleased this quarter to announce an innovative partnership with Walgreens to which we are creating a 90 day at retail pharmacy offering. This is all about meeting consumers where and when they want whether that means home delivery or walking into the local Walgreens store. Together, will provide choice and cost savings to our clients as we work and benefit together in a meaningful more collaborative way. We are enthusiastic about the potential of the extension of our relationship with Walgreens, the largest retail pharmacy in the U.S. Overall, this year we expect OptumRx to generate more than $58 billion in revenues and manage nearly $80 billion in pharmacy spend for our customers including $30 billion in specialty drug spending. Pharmaceutical spending comprises 12% to 15% of the overall cost of health benefits and has been the traditional focus of the pharmacy benefits industry. We find that focus much too limiting when it comes to improving health and healthcare overall. The impact OptumRx has on healthcare and its cost has the potential to be profoundly broader and deeper. Here you have the most frequent consumer touch point in all of healthcare, one that provides great visibility into the full healthcare continuum. An individual's engagement with OptumRx becomes more impactful when we break out of the one-dimensional procurement and formulary arbitrage model of today and open up providing consumers integrated medical and pharmaceutical services. In the process, we help reduce unnecessary overall systems utilization including ER visits, hospital admissions and readmissions and provide more effective and timely interventions to improve adherence and health outcomes. That's the value proposition of the future we are focused on. Employers using our integrated and technology enabled approach can save in excess of $120 per member per year across their combined medical benefit. In summary, our objective for the impact of this business goes far beyond traditional pharmaceutical management to where the potential to influence both the consumer and the health system for the better is much greater. That is why pharmacy care services are core to our growth and value story over the next decade. Optum also is delivering differentiated value from our work inside the health systems. Our second core to our growth are unrivaled existing capabilities in healthcare data science and analytics. Companies new to the space are excited about the potential that someday these forces will vault healthcare into a new age. For Optum's customers, that someday is today. We are meeting their critical needs right now. We are the leader in using advanced technology and predictive analytics to connect stakeholders across the care continuum with the insights to better manage the health of populations and the resources they depend on. Our continuously updated, integrated and curated clinical and claims data asset comprises more than 80 million lives of robust clinical data and 170 million lives of claims data. We can see from both sides. Beyond the 250 million clinical and administrative lives, our diverse and comprehensive data set includes 8 billion lab results, 4 billion determinations and 3 billion medical procedures. We can provide a real-time clinical and financial picture that is fully integrated and spans years of longitudinal detail. Our health data resources continued to grow securely and responsibly every day. Today, our analytics products are helping thousands of care providers. And ultimately, the millions of consumers they serve translate data into action and action into better medical outcomes. Today, not someday, we help our customers step up from reacting to challenges to designing and implementing actions that reliably lead to better health delivered at lower cost. Today, we are delivering the wealth of information, analysis, and positive benefits of big data with results that include double-digit improvements in critical performance factors like utilization and chronic disease control, which in turn empower care providers to adopt and succeed in new models of care and related new revenue streams. Today, we lead the way in implementing predictive analytics in healthcare because healthcare is all that we do. Healthcare technology and data analytics have been our specialized focus for years. So while others learn to crunch large amounts of static data, Optum is fully integrated into the live flow of healthcare transactions, enabling us to provide up-to-date useful information that makes the healthcare system more intelligent and enables it to act that way. Now, let me turn it over to Dave.
David Scott Wichmann - President & Chief Financial Officer: Thank you, Larry. As we open 2016, UnitedHealthcare's momentum continues. Strong new customer growth and historically high retention levels reflect the competitive value UnitedHealthcare offers in the marketplace. Quarter by quarter and year by year, we continue to gain new customers and retain valuable established customers who choose the combination of our more engaging consumer experience, distinctive service, product innovation, and integrated clinical and network value. People using our modern consumer-based benefit designs are supported by actionable information available at their fingertips, enabled and delivered by advanced analytic capabilities, as Larry just described, increasingly channeled through consumer and care provider-friendly mobile technologies. Employers continue to be drawn to well-managed competitive cost trends, physician and consumer engagement, and value-based arrangements for care delivery. We partner with our largest customers to benchmark performance and design customized plans that help them advance year by year along the continuum of ever-improving benefit performance and heightened consumer engagement. And we are serving individual patients and overall populations with more complex medical conditions. Our coordination of services and ability to close gaps in care significantly increase the value we bring to consumers and customers. Simply put, the greater the level of patient needs, the more we can help. As a result, we continue to deliver exceptional organic growth. Our U.S.-based benefits businesses grew organically to serve 1.3 million more people with medical benefits in the first quarter, and that brought organic growth to 2 million people in the past year. Looking at commercial markets, we are up about 700,000 people in the quarter and 1 million people since March 2015. First quarter 2016 delivered diversified growth across self-funded national accounts, public sector, small groups, middle-market businesses, and individuals. Turning to exchanges, as we expected when we spoke with you in January, we grew roughly 300,000 lives through the first quarter and served 795,000 people on public exchanges as of March 31. We expect that level to decline to around 650,000 by December. Through this first quarter, we have seen no change in our estimates of cost from the 2015 exchange period. This quarter, with the majority of our 2016 exchange members new to us, we have been appropriately cautious in our reserve estimates, reflecting an additional $125 million in full-year 2016 exchange losses. These were fully absorbed in this quarter and fully considered for the year in our guidance range. And as Steve mentioned, we do not anticipate financial exposure to exchanges in 2017. In Medicare, the value of our Medicare Advantage offerings continue to resonate, differentiated by the stability of our benefits, networks, membership, and distribution systems. We offer seniors clear value and a consistent modern consumer experience, all of which drive new growth as well as strong consumer retention. This strength is reflected in our first quarter membership growth of about 300,000 seniors. Medicare is a consumer business, with seniors receiving a variety of outreach approaches focused on better and more consistent care, such as receiving home visits, and benefiting from our personalized, compassionate, and education-focused consumer service. In 2015, we helped close 9 million gaps in care for seniors we serve. And we expect nearly 65% of our members to be in a four-star plan by 2017, with further improvement in that percentage in 2018 to 80% or more. We believe our Medicare prescription drug benefit business will be much better positioned for 2017. We've pulled back in a number of markets this year to reposition products and added membership and the new product potential via a modest acquisition in the first quarter. Our Part D membership decreased 70,000 people in the first quarter and should decline by another 200,000 or so by year-end. This suggests we will serve 4.7 million to 4.8 million people by year-end 2016, considerably better than what we projected last December. And we expect to return to growth in Medicare Part D in 2017. Switching to Medicaid, managed care serves as the most effective proven tool to ensure budget sustainability for state Medicaid programs. This financial predictability along with the ability of managed care to expedite systems transformation, comprehensively integrating care while addressing social determinants, has resulted in an unprecedented level of procurement activity. Of special note is the significant increase in the volume of opportunities for populations with more complex needs, such as people served by long-term services and support programs. The recent award of Nebraska's integrated health, behavioral, and pharmaceutical model reinforces these expected trends in procurement to include more populations with more complex needs and to look to integrated solution to address state's needs. Our expectation for continued expansion of opportunities to serve all Medicaid populations was reinforced by our recent award in two California counties and across our community and state business the addition of 145,000 people in the first quarter. Let me now touch on the outlook for UnitedHealth Group as a whole. Building on the strength of our first quarter, we expect full year revenues of approximately $182 billion, up from our prior outlook of $180 billion to $181 billion led by strength in OptumRx and UnitedHealthcare Employer & Individual. Strong first quarter results combined with a slightly lower tax rate for the balance of the year and the impact of recently completed acquisitions allows us to increase our outlook for adjusted net earnings by $0.15 to a range of $7.75 to $7.95 per share. We continue to foresee cash flows approaching $10 billion. As you know, we expect Optum to grow full year operating earnings by more than 30% in 2016. We continue to expect seasonality to be a factor in our overall earnings results. Similar to years past Optum expects to generate in the area of 60% of its operating earnings in the second half of the year while the current consensus view appears to be modestly more first-half biased. Taken together, this suggests that updates for full year UnitedHealth Group earnings per share estimates after recognition of our first quarter performance would most appropriately be focused on the second half of this year. Turning to capital, we closed the quarter with a strong balance sheet. We expect share repurchase activity to be more pronounced in the first half of this year with the second half focused on debt reduction toward targeted levels and we will see our dividend levels – we will address our dividend levels at our June board meeting as we do each year. Steve?
Stephen J. Hemsley - Chief Executive Officer & Director: Thank you, Dave. Today we are in a strong position at a unique moment in time. We have the opportunity to considerably elevate our performance around quality and customer satisfaction, delivering greater value and driving unparalleled organic growth across our entire franchise. While remaining as always disciplined on pricing and cost management. We are focused on delivering higher quality at every touch point with every customer and consumer, doing this well elevates customer trust and loyalty, loyalty that becomes the foundation for an extended period of growth benefiting consumers, society and shareholders. We're intensely focused on this agenda and expect it will produce strong clean results in 2016 and a positive view of opportunities in 2017 and the decade to come. So thank you for your interest today. And operator, could we please open for questions, again one per analyst please this morning. Thank you.
