Thank you, John. Hello, and welcome to our conference call and the opportunity to discuss our results. As you saw in the release last night, we achieved our adjusted net sales and EPS targets for the second quarter and reaffirmed our full year guidance for our adjusted net sales and earnings targets based on the performance for the first half of 2013. We had strong demand for our portfolio of Molecular Diagnostics growth drivers and delivered higher sales in this overall customer class, despite the anticipated slowdown in revenues related to HPV screening. In the Life Sciences, we saw a different picture than in the first quarter of 2013 with growth in Pharma and Academia, but weaker results in Applied Testing. All regions contributed to growth and were led by the top 7 emerging markets. We're making progress on our goals for 2013. In Personalized Healthcare, a highlight was the recent FDA approval of our EGFR companion diagnostic kit. This was granted simultaneously with the FDA approval of Gilotrif, which is the brand name for afatinib from Boehringer Ingelheim, as the new first-line treatment for non-small cell lung cancer. We also reached new confidential agreements for companion diagnostic co-development projects, both within existing partners and also with new pharma companies. We are on track to begin the launch of our sample-to-insight next-generation sequencing benchtop workflow in 2013. We have reached an important milestone with placements at early access customers. Our ambition is to drive the use of this breakthrough technology in clinical research and diagnostics by offering a fully integrated workflow from biological sample to highest-quality data interpretation and actionable results. The very positive response to our Ingenuity acquisition reaffirms our conviction that our gold standard in biological data interpretation will be a crucial differentiator for QIAGEN. It is not just about sequencing samples, but instead, about offering a complete, high-quality workflow and one that provides the most powerful insights. In terms of the QIAsymphony automation system, placements continue at a strong pace with placements up 15% in the first half of the 2013 compared to the same period in 2012, which was already a record year for QIAsymphony. We are well on track to break through 1,000 cumulative installed systems during 2013 and continue to see robust double-digit growth in consumables. And the last point to mention on this slide is of the completion of the major efficiency project that we began in late 2011. QIAGEN has been going through a transformation as we streamline the organization consolidated sites and reallocated resources to growth initiatives following a series of bolt-on acquisitions. The last set of actions involved resigning the sales and regional marketing teams in the United States and Europe. Given the changes in our markets and also the QIAGEN portfolio, we wanted to better address customer needs across the continuum from basic research to translational medicine and into clinical diagnostics. We continue to have the only U.S. clinical sales force in the Molecular Diagnostics industry and a strong share of voice in our market segments. As Roland will discuss later, the restructuring charges for these projects are going to end in 2013, and we realize that it is time for us, even in more in light of these charges, to deliver on generating tangible benefits for these actions. We are convinced that these actions have strengthened QIAGEN considerably and will play a key role in accelerating sales growth and improving profitability. Finally, you saw in the release that we announced plans for a new $100 million share repurchase program. This is a signal of our conviction in the growth opportunities of QIAGEN, especially as we complete the sufficiency program and also that we are not satisfied with the current valuation. As we launch this program, we are maintaining our flexibility to take advantage of strategic opportunities, while increasing returns to shareholders. Turning to Slide 5. I would like to review the results of our customer classes. Molecular Diagnostics led the performance and provided about half of sales. In Prevention, the QuantiFERON latent TB test continued to grow at a 20% plus constant exchange rate growth rate with the fastest growth in the United States. Our teams are driving conversion based on QuantiFERONs superior accuracy and aided by delivery problems for the tuberculin, the derivative needed for the 120-year-old competing TB skin test. In Personalized Healthcare, we saw a mixed picture. Sales of companion diagnostic kits rose at a double-digit pace but the Pharma co-development project provided lower revenues. We are seeing improved demand for Companion Diagnostics in the United States as uncertainty over reimbursement is clearing up, and we expect new growth impulses from the EGFR approval. Our Profiling business, again grew at a good pace, supported by rising sales of consumables used on QIAsymphony. As I mentioned QIAsymphony placements are growing at double-digit pace. And the related assets in Consumables sales are also growing at a high double-digit rate. The majority is in Molecular Diagnostics and the percentages placed as reagent rentals continue to rise. Although we are creating multiyear revenue streams, this weighs on current instrument sales. Staying [ph] in Molecular Diagnostics, sales of products for HPV testing fell 17% in the second quarter, which is more than the single-digit decline in the first quarter, but this is something we had anticipated and there are some year-over-year baseline reasons. It is more important to look at the year-to-date trends. For the first half of the 2013, global HPV sales are down about 10% constant exchange rate representing 15% of total sales and we continue to expect about a 10% decline in HPV sales for 2013. The challenges are in the United States where we face significant pricing pressure as new competitors search for market share gains. QIAGEN maintains a solid leadership position in the United States with our test ranking as the gold standard. We announced in June that a major U.S. reference lab had reached a new nonexclusive agreement to consolidate the purchase of women's health screening products and I want to make a few points. First, they will continue to offer our HPV test to customers. Second, the transition to the competitor HPV test is 1 of 4 products trying to be converted simultaneously and this will take time. And third, we see no signals of other laboratories wanting to consolidate suppliers. The reason is clear, labs want to have the freedom and flexibility to adapt. They also want to offer gold standard tests since this is what customers are demanding and no single supplier can do so across a broad menu. Our position as the gold standard is the key reason why labs are sticking with our HPV test. We continue to sign labs to new multiyear agreements and we'll remain the market leader. As for the impact in 2014, we expect this customer development to have an adverse impact on our results but this is to represent less than 2% of our anticipated 2014 total adjusted sales at the worst. We also continue to expect U.S. HPV product revenues to represent less than 10% of total sales in 2014. Before moving on, I would like to note that Ingenuity revenues were booked in the Pharma and Academia customer classes. As I mentioned earlier, we saw a change in trends in the Life Sciences from the first quarter of 2013. Applied Testing sales were down and faced a tough comparison to the outstanding instrument sales in 2012. However, we saw solid growth in consumables, and we expect overall positive trends here for overall 2013. Finally, a return to growth on higher sales in all regions after the significant slowdown in the first quarter. Academia sales were also slightly higher in comparison to the second quarter of 2012 as emerging markets more than offset the ongoing cautious spending in the United States and Europe. In the U.S., sales are obviously, under pressure due to sequestration. But we are not experiencing market share losses, just overall restrictions on spending. The European landscape did not change during the quarter as we continue to see cautious spending patterns. Also the anticipated government funding impulses in Japan have not yet materialized. And now on Slide 6, to review the completion of our major efficiency project. We have made transformational changes that were designed to address the fast-changing industry conditions, as well as issues specific to QIAGEN. These included the reallocation of resources to growth initiatives, in particular to nextGen sequencing. The sufficiency project had 5 areas of focus and we have streamlined organizational structures and eliminated duplication. We focused our R&D portfolio and project to offering high growth potential and improved processes to accelerate innovation. We improved capacity utilization to increase efficiencies by closing down some sites as well, such as Hamburg, Morgan and Crawley. We optimized sales and marketing channels to better identify address customer needs, we captured savings from the expansion of shared services, such as the new service center in Poland and the outsourcing of some IT activities creating functions that can be efficiently scaled as QIAGEN grows. We've taken a $76 million pretax charge in operating income in the second quarter and this was to cover the following types of initiatives. One, closing some sites and integrating their activities at our global hubs in the United States, Germany and China to gain efficiencies. Two, financing changes in our R&D portfolio to put more emphasis on faster growing areas. This included allocating more resources to the NGS initiative and deemphasizing HPV-related R&D projects. And last, changes we have made in our commercial and marketing organizations. So the question is, why were they charged much higher than we had forecast? The answer is that we decided to take the opportunity to accelerate and expand the range of efficiency projects, which we had originally planed in light of industry trends, including M&A actions. We want to get this finished and we have. Many of you know QIAGEN well and some of you are very familiar with the new structures, processes and initiatives. The company is quite transformed and we are using this strength to push for higher growth. We are convinced that the benefits of these actions will become even more evident in 2014 and beyond. This was one of the motivators behind the decision to launch a new share repurchase program. I would now like to hand over to Roland.
