Thanks, Tom. This morning I'll review the quarterly performance of our major business segments, Pharmaceuticals, Nutritionals, and Medical Products, including Diabetes Care, Diagnostics, and Abbott Vascular. So let me start with our medical products businesses, where sales increased 14.7%. In our Vascular business, global sales were driven by 35% growth internationally as we continue to gain market share with our drug-eluting stent, XIENCE V. The XIENCE PROMUS platform is now the market leader in Western Europe surpassing Endeavor, Cypher and Taxus. As a result, in the second quarter, our global DES franchise sales, which include XIENCE, as well as other third-party DES product revenues were $125 million, more than double over the prior-year quarter, and up 25% sequentially from the first quarter. As a reminder, our DES franchise sales include XIENCE PROMUS and the Medtronic royalty. Following the FDA approval two weeks ago today, Abbott's Vascular sales force immediately began launching XIENCE in the U.S. We're pleased to bring this superior product offering to market providing a new alternative to the approximately 13 million U.S patients who have coronary artery disease. XIENCE is a true next generation drug-eluting stent with superior performance and durable clinical benefits. With XIENCE, physicians retain the best-in-class deliverability they've become accustomed to with our market-leading MULTI-LINK vision bare metal stent system which, as you probably know, has a more than 60% share in the U.S. While we are in the early days of the U.S. XIENCE launch, we're very pleased with our progress to date. The anecdotal feedback has been extremely positive and demand is, quite frankly, better than expected. XIENCE is clearly the preferred product of interventional cardiologists based on its clinical data and other distinct performance attributes. Our goal within the first 30 days of launch is to penetrate the majority of accounts that represent a significant percentage of total U.S. procedure volume. So, although it’s still very early, based on the first two weeks of launch we are right on track with our weekly launch goals, if not ahead. Looking at the DES market broadly, we continue to see steady improvement. U.S. PCI volumes continued to improve on a sequential quarterly basis and U.S. DES penetration is now in the high 60% range. We priced XIENCE to recognize the fair and appropriate value of the product, including its superior clinical data, improving premium attributes. As a reminder, the U.S. launch of XIENCE is supported by outstanding clinical data. XIENCE is the first and only drug-eluting stent that demonstrates superiority over the market-leading DES in two randomized controlled clinical trials. XIENCE robust clinical program includes long-term data from the more than 1,300 patients enrolled in SPIRIT I, SPIRIT II and SPIRIT III trials, as well as the continued access and post-approval programs. Last week we began enrolling our XIENCE V USA post-approval study, which will evaluate patients over the course of five years. This study will allow physicians to further review the safety and efficacy of XIENCE V in a more complex patient population and continue to gain experience using the product. Two-year data from our larger 1,000 patient U.S. pivotal trial SPIRIT III which we presented at EuroPCR in May demonstrated the sustained efficacy and safety of XIENCE. Patients treated with XIENCE experienced better long-term clinical outcomes, and lower rates of stent thrombosis from patients treated with TAXUS. And we're seeing the differences between XIENCE and TAXUS increasing over time. At two years in SPIRIT III, XIENCE demonstrated the following results, a clinically superior 45% reduction in the risk of major adverse cardiac events or MACE, a clinically superior 32% reduction in target vessel failure or TVF and a low rate of very late stent thrombosis between one and two years for the ARC definition. Also in the second quarter, we received approval for XIENCE in South Korea and submitted a marketing authorization license for XIENCE in Japan. The application for Japan included safety data from the SPIRIT III clinical trial, including data from a Japanese patient population. We’re forecasting a XIENCE launch in Japan, at this time in the second half of 2009. Also in the quarter, we launched StarClose SE, our next generation vessel closure device, and we did that worldwide. StarClose SE builds upon the premium clip-based design of its predecessor, StarClose with improved ease of use features. So, as we look ahead to the third quarter, we expect global Vascular sales to grow very strong double-digits as we continue to gain share with XIENCE and build on the successful early U.S. launch. We expect DES franchise sales to nearly double again from the second quarter to approximately $225 to $250 million in the third quarter. Let me turn now to our worldwide Diagnostics business, where sales grew more than 17% in the quarter with continued strong growth in our international business. We saw 16% growth in our Core Diagnostic segment this quarter. This included double-digit growth in the U.S. and internationally. ARCHITECT sales were up double-digits worldwide, as we continue to improve the menu in the United States and introduce new systems. We recently launched the ARCHITECT i1000 immuno assay instrument for lower volume labs. Early customer feedback for the i1000 has been positive as we have already placed more than 200 instruments into the market. We’ll showcase the i1000 and other ARCHITECT instruments at the upcoming American Association of Clinical Chemistry or AACC on July 27 to the 31 in Washington, DC. Strong PRISM sales helped drive U.S. performance in the quarter as well as customers added the higher… highly anticipated HTLV test for their instruments. Emerging markets continue to represent a promising opportunity for future growth in our Core Diagnostic business, as we saw a double-digit growth this quarter in both Latin America and China. Efforts to improve profitability continue to be a significant focus in our Core Diagnostics business, as we evaluate ongoing opportunities to reduce overall costs and continue to improve efficiencies. We're encouraged by the early outcomes of our efforts and anticipate continued margin improvement in that division in the years ahead. In our Point of Care business, sales grew nearly 20% in the quarter. Growth was driven by strong cardiac cartridge sales and further penetration of our CHEM 8 test, which received acclaim for broader use last year. And in Molecular Diagnostics, sales this quarter increased more than 25%. Placements for our m2000 Real-Time PCR system were up worldwide. In the quarter, we received CE Mark for a hepatitis C genotyping assay, further expanding our infectious disease menu on the m2000. We also plan to launch an HPV test for the m2000 internationally by year-end. In the U.S., we recently received approval for a Chlamydia Gonorrhea PCR test and have ongoing clinical trials for hepatitis C and B assays. In the quarter, we made an equity investment in Ibis, a subsidiary of Isis, for the development of a new cutting edge molecular diagnostics technology for the future. So, looking ahead to the third quarter, in our worldwide diagnostics businesses we anticipate continued double-digit growth. In diabetes care, sales increased more than 9% globally in the quarter, driven by strong international sales and increasing adoption of our new no-calibration meters, FreeStyle Lite and FreeStyle Freedom Lite, which eliminate the manual calibration step required by most glucose meters, improving convenience for people with diabetes. In the U.S., sales growth was impacted by the comparison to the prior-year, when FreeStyle Lite was first launched. In the quarter, we had strong meter placements, representing good prescription growth. We've seen positive share results from a promotional program we initiated last quarter. In the third quarter, we expect approximately 10% growth worldwide in Abbott diabetes care. Moving to our global Nutritionals business, sales were up more than 12% in the quarter, driven by 21% growth in international Nutritionals, as demand continues to increase for high quality nutritional products, particularly in emerging markets. We continue to see double-digit growth across both pediatric and adult nutrition products internationally. U.S. Nutritionals sales were up mid-single digits, driven by strong sales of PediaSure, ZonePerfect and Glucerna. Our Similac infant formula brand continues to gain share thanks to the successful introduction of Similac Sensitive, a formula for babies with lactose sensitivities. In the third quarter, our Nutritionals business we expect continued strong double-digit growth internationally and continued mid-single digit growth in the US. Turning to our global Pharmaceuticals business, where sales increased nearly 17% in the quarter led by strong reported growth of nearly 27% in international Pharmaceuticals. We expect double-digit sales growth for our global Pharmaceuticals business to continue in the third and fourth quarters, with double-digit growth projected for both the U.S. and international businesses. U.S. pharmaceutical sales this quarter increased high single digits, despite a difficult comparison to the prior-year, reflecting strong double-digit growth for HUMIRA, Niaspan and Synthroid. Partially offsetting this performance was the negative impact of generic competition for Omnicef, as well as some modestly lower wholesaler buying this quarter. In Immunology, worldwide HUMIRA sales this quarter were up nearly 50% to $1.1 billion, including more than 70% international growth. Today, based on the strength of our HUMIRA sales so far this year and our outlook for the remainder of this year we're raising our forecast for full-year global HUMIRA sales to more than $4.3 billion. Earlier this year, we launched HUMIRA for psoriasis and the results have continued to exceed our expectations. Our U.S. new prescription share in dermatology has doubled since approval, reaching nearly 30%. More than 3,700 dermatologists have written prescriptions for HUMIRA with nearly 1,000 dermatologists writing HUMIRA prescriptions for the first time since our psoriasis approval in January. This significant increase in HUMIRA used by dermatologists is promising for the future, because once the profound efficacy is experienced first-hand by a physician, we know they're more likely to prescribe HUMIRA again. Our early success in this market is based on differentiating clinical data. We've demonstrated that more than 70% of HUMIRA psoriasis patients achieved a 75% reduction in their symptoms and a remarkable 20% of patients achieved 100% reduction or complete clearance. Based on outstanding clinical data in the more than a decade of clinical experience with HUMIRA now, we believe we're well positioned for continued success in the dermatology market. We also continued to see steady growth for HUMIRA in Crohn's disease, with total share recently surpassing 40%. HUMIRA continues to offer the only self-administered biologic treatment for Crohn's patients providing a distinct convenience advantage over the competition. Other biologic treatments require IV administration or must be reconstituted and administered by a healthcare professional via multiple injections in the office. During the quarter, we presented new longer-term Crohn's data at this Digestive Disease Week meeting or DDW, demonstrating HUMIRA’s sustainability of remission with three out of four patients maintaining remission out to two years. These data are important because Crohn's disease is a lifelong and serious [ph] condition with no cure and patients need treatments that demonstrate sustained remission over time. We also presented new data at the European League Against Rheumatism or EULAR meeting demonstrating HUMIRA’s proven durability of response across our full suite of rheumatic disease indications. That's rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis and that was out to seven years. Additionally, results from analysis of open label studies of HUMIRA in these three distinct indications demonstrate HUMIRA's effectiveness in patients with a previously inadequate response to other anti-TNF therapies. These data coupled with a five-year radiographic progression data that’s currently in HUMIRA's label, underscore HUMIRA's proven ability to halt disease progression and effectively treat rheumatic disease over the long-term. HUMIRA continues to represent a major growth driver for the company out through the next several years at least with significant opportunity remaining in both U.S. and international markets where penetration rates are currently in the single-digits for biologics. Today, the global biologics market for all HUMIRA indications is approximately $14 billion and that's estimated to exceed $20 billion by 2012. In our lipid management franchise in the second quarter, our growth continues to outpace the overall cholesterol market. Niaspan sales were $194 million in the quarter up nearly 14%. Currently more than one million patients are on Niaspan therapy. We presented additional pivotal Phase III clinical results on our next generation fenofibric acid molecule, TriLipix at the National Lipid Association’s 2008 scientific sessions. Data from a study of more than 1,400 patients with mixed dyslipidemia demonstrated that TriLipix given in combination with Astrazeneca's Crestor met its primary endpoints and led to greater improvements across all three key lipids compared to monotherapy. We also presented data on TriLipix Crestor at the American Diabetes Association annual meeting that demonstrated that TriLipix in combination with Crestor improved key lipids in patients with Type 2 diabetes. Patients with Type 2 diabetes often are at risk for cardiovascular events because of multiple risk factors including lipid problems and the patients with diabetes typically have mixed dyslipidemia at higher rates than non-diabetic patients, a factor that elevates treatment urgency. Of the more than 21 million American adults with diabetes, more than 14 million have problems affecting one or more of the three key lipid parameters. As a reminder, these results add to our existing TriLipix data package, including data presented earlier this year demonstrating efficacy and safety of TriLipix in combination with other two leading statins, Lipitor and Zocor. Our three combination studies along with the 52-week long-term open label expansion study are part of the largest clinical program to date designed to evaluate the safety and efficacy of a fibrate in combination with statins. We submitted TriLipix for FDA approval at the end of last year and remain on track for FDA approval in the fourth quarter of this year. The next step in our development program is our partnership with Astrazeneca to combine TriLipix and Crestor as a Fixed-Dose therapy. The strong data presented at NLA and ADA bode well for our development program for this promising Fixed-Dose therapy. This combination product is in Phase III development and we expect to submit for regulatory approval in the second half of next year. With many unique therapies that address lipid problems beyond LDL alone, Abbott's lipid franchise is clearly uniquely positioned to address the growing need for comprehensive lipid management now and over the longer term. So for the full year, we expect double-digit growth in our lipid franchise. Moving on to HIV, where Kaletra was up double-digits worldwide in the quarter to $355 million, driven by continued success of the tablet launch in international markets and sales of Synthroid this quarter were up in double digits increasing nearly 12% in the US. Regarding Depakote during the quarter, we resolved our Depakote ER litigation with a number of companies providing more certainty around the ER franchise. As a result, we anticipate generic competition for Depakote ER on January 1 of 2009. We continue to expect generic competition for Depakote ER upon expiration of pediatric exclusivity later this month and that's all factored into our forecast and plans. Moving on to Lupron, where this quarter we integrated the Lupron franchise following the equal split of our TAP joint venture in the conclusion of that agreement and we began selling the hormone therapy Lupron as part of our U.S. pharmaceuticals business. U.S. sales of Lupron this quarter were $81 million reflecting a partial quarter of sales, following conclusion of the joint venture. Lupron sales in the quarter were lower than forecasted due to the commercial transition of the product from our previous TAP joint venture to our Abbott commercial organization. However, we continue to forecast Lupron sales approaching $400 million in 2008 as we previously indicated. So in summary, in Pharmaceuticals, for the third quarter and for the full year, as I mentioned, we expect double-digit sales growth for both our U.S. and international pharmaceutical businesses. And finally, as Tom mentioned, our broadbased pipeline continues to be highly productive with eight new major regulatory approvals so far this year in 2008 including four approvals in our pharmaceutical business and four approvals in Medical Products with XIENCE V obviously being approved just two weeks ago today. We anticipate approval of our next generation fenofibric acid product, TriLipix as well as our controlled-release branded pain medication, Vicodin CR by the end of this year. In our earlier stage pipeline, we presented data from our novel oncology compounds at ASCO in May. We also have innovative research programs in neuroscience, where programs are underway to address such conditions as ADHD, Alzheimer's disease and schizophrenia. We continue our work in immunology with ABT-874, our IL-12/23 product in late-stage development as well as other innovative treatments including oral therapies and other biologic targets. And in Abbott Vascular, we are leading the way in the development of truly revolutionary new stent technology with our unique and one-of-a-kind bioabsorbable stent program. So in summary, the Abbott management team, we are all very pleased with our overall strong performance from our diverse mix of global businesses and truly best-in-class products including such products as HUMIRA and XIENCE V that are meeting the critical needs of today's patients. So with that, we'll be glad to take questions, operator. Question and Answer
