Good morning. I am very pleased to say that strong financial performance we experienced in first quarter, continues in the second quarter of 2016. All three business segments reported revenue gains which demonstrates, continued solid execution of our business strategy, successful initial integration of well research, and our ongoing focus on exceptional client service. As a result, clients continue to choose to partner with Charles River for our science, our support, and the increasing breadth of our portfolio, which provides wider opportunities for them to leverage our expertise, to achieve their goals faster, more efficient, and productive to our research. I would like to provide you with highlights of our second-quarter performance. We reported revenue of $434.1 million in the second quarter of 2016, a 27.8% increase over the second quarter of 2015. At 0.4%, the negative impact of foreign exchange was minimal. Acquisitions contributed 19.4% to second-quarter revenue growth, and our legacy businesses generated 8.7% organic growth, similar to the first quarter and in line with our long-term high single-digit target. Both the legacy microbial solutions in safety assessment businesses generated growth in excess of 10%, and we were also pleased to see 4% growth in RMS. From a client perspective, biotechnology clients were the primary driver of revenue growth. Sales to these clients increased at a double-digit rate, as they continued to invest in their pipeline. The operating margin declined 50 basis points year over year to 19.5%. The decline was due primarily to the acquisition of WIL, which, as we have mentioned has an operating margin below our DSA segment level. Our goal to achieve $17 million to $20 million of cost synergies over two years will improve WIL's operating efficiency. I am pleased to say we are making excellent progress on synergies and fully expect to achieve our goal in 2017. Earnings per share were $1.20 in the second quarter, an increase of 25% from $0.96 in the second-quarter 2015. The improvement was due primarily to a combination of higher revenue generated by our legacy operations, and the benefit of our acquisitions, particularly WIL. Second-quarter earnings per share also benefited from our venture capital investments, which contributed a gain of $0.06. We were exceptionally pleased to see such robust performance across our portfolio in the second quarter. On the strength of our second-quarter results and our expectations for the second half of the year, we are raising our revenue guidance range by 100 basis points, for both reported and constant currency. The increase reflects an organic growth rate of 7% to 9%, compared to our previous expectation of 6% to 8%. We are also increasing our 2016 non-GAAP earning per share guidance to a range of $4.40 to $4.50, which is $0.065 higher at the midpoint of the range than our original guidance. We are confident that we will achieve our full-year revenue and earnings per share guidance. I would like to provide you additional details on our second-quarter segment performance, beginning with the RMS segment. Revenue was 125.1 million, an increase of 4% in constant currency over the second quarter of 2015. Growth was driven by higher sales and research models in China and research model services. Revenue from services was robust in the quarter with our GEMS, RADS, and insourcing solutions businesses, all reporting revenue growth. The RMS operating margin declined slightly in the second quarter to 28.9% from 29.1%. The 20 basis point change was due primarily to a greater proportion of services in the revenue mix. Operating margins for the product businesses are higher to increasing service revenue did impact the margin. However, higher revenue in our continuing efficiency initiatives are driving operating margin improvement for our service businesses. Revenue for the manufacturing support segment was $87.9 million, a 31.3% growth rate in constant currency, over the second quarter of last year. The acquisition of WIL's CDMO businesses, Celsius and Sunrise, contributed 18.4% of growth. On an organic basis, growth was 12.9%, driven primarily by the microbial solutions and biologics businesses. Microbial solutions reported an exceptional second quarter. With the upgrades to our manufacturing plant completed and production capacity increased, the first quarter backlog was filled. Combined with robust sales of PTS products, core reagents, and microbial identification services, the legacy microbial solutions business generated revenue growth in the second quarter consistent with our target, which is greater than 10%. We had continuing to drive adoption of the PTS family of products, which is the only rapid endotoxin testing platform and at the same time, focusing on expanding our footprint in the market for rapid testing and microbial identification. As the only provider who can offer a comprehensive solution for rapid quality control testing of both sterile and nonsterile biopharmaceutical and consumer products, we are in a unique position to support our clients' rapid testing needs. We are investing in research and development for the microbial solutions business to enhance the functionality of our rapid testing platform, and drive greater adoption of our products in order to capitalize on this moment in time, when we have the opportunity to set the standard for rapid testing and identification. We are optimistic that our ability to provide a total microbial testing solution for our clients will be a driver for microbial solutions to continue to deliver at least low double-digit organic revenue growth for the long-term foreseeable future. The biologics business reported a very strong year-over-year performance in the second quarter, with robust revenue growth as a result of strong demand for our biosafety and cell banking services. As we mentioned previously, the biologics business supports the development of biologic drugs, which are representing an increasing proportion of drugs in development. Furthermore, the number of biosimilars in development is also increasing, adding to the demand for our services. In order to further strengthen our services portfolio, we recently acquired Blue Stream laboratories, an analytical CRO supporting the development of complex biologics and biosimilars. Located proximate to both our headquarters and our safety assessment facility in Massachusetts, Blue Stream is recognized for its expertise in structural and functional protein characterization programs, and the development and validation of assays for current good manufacturing practice, law release, and stability programs. Although this is one of our smaller acquisitions, Blue Stream was a strategically important target, because its capabilities fit so well with ours. As a result of the acquisition, we can now provide a comprehensive portfolio, of both bioanalytical and biosafety testing services, with the ability to support biologic and biosimilar development from discovery through clinical phases and commercial manufacturing. The manufacturing segment second-quarter operating margin was 35.4%, a 190 basis-point increase year over year, and well above our low 30% target. The improvement was driven primarily by the microbial solutions and biologics businesses. In both cases, increased volume and the benefit of efficiency initiatives contributed. DSA segment revenue was 221.1 million in the second quarter, a 45.6% increase in constant currency over the second quarter of 2015. The acquisitions of WIL and Oncotest contributed 35% to the segment's second-quarter growth. The organic revenue growth of 10.6% was driven primarily by the safety assessment business, which reported a double-digit revenue increase over the same period last year. We were exceptionally pleased with this performance, which resulted primarily from improved client demand, especially from our biotech clients, and the successful execution of our targeted sales strategy. The DSA segment's operating margin was 21.2%, a decline of 40 basis points from 21.6% from second quarter of 2015. Margins in both the legacy discovery and safety assessment businesses improved, but as expected, the addition of WIL slightly depressed the segment operating margin. We are making excellent progress on the cost synergies, and expect WIL's margin to improve. But it will continue to modestly reduce the DSA segment's operating margin at least through the end of 2016. The discovery services business performed well in the second quarter. We are beginning to gain meaningful traction on integrated discovery work, and have recently signed three new deals in different therapeutic areas: ocular, oncology, and ALS. We continue to make progress with our efforts to inform our client base about the breadth of our unique portfolio, and the value of working with a single partner through a larger portion of the early-stage drug research process. The decision process is lengthy, but there is great potential for growth and outsourcing of discovery. We have a reputation for the scope of our expertise, which is one of the critical factors in our clients' choice to partner with us. We are continuing to enhance that expertise through acquisitions and partnerships, particularly with academic institutions, or often on the cutting edge of research. As a result, we believe that as outsourcing increases, we will be the partner of choice for discovery services. Our safety assessment business had a very strong quarter, with all of our facilities reporting higher revenue and WIL exceeding our expectations. As a result of our dedicated focus on portfolio expansion, enhancing our scientific expertise, improving our operating efficiency, and developing flexible and customized working relationships with clients, we are positioned exceptionally well to provide the support which our clients require in order to expedite the drug research efforts. And with the acquisition of WIL, our extensive capabilities and scale present an even more compelling value to our clients, whether they are global biopharma companies increasing their reliance on CROs, or small and midsize biotech companies, which have always relied on external resources. As clients have increasingly chosen to work with us, capacity at our safety assessment sites has continued to fill. We are operating near optimal capacity and our backlog is increasing. Opening Charles River Massachusetts provided some infrastructure to accommodate growth. Clients are especially interested in placing GLP studies in Charles River Massachusetts, and we expect to be able to accommodate them by early 2017. The strategic collaboration with Moderna Therapeutics, which we announced on June 6th, was based in part on the proximity of Charles River Massachusetts to Moderna's operations in Cambridge, which allows their scientists to work side-by-side with ours. The integration of WIL is progressing very well, and I am pleased to say we have accomplished the major goals we set for the first 120 days. Chief among those was integration of WIL's workforce and its clients. We assured both constituencies that the combination of Charles River and WIL would not create disruption and, in fact, would provide expanded career opportunities for employees, and broader support for clients' drug research efforts. Initial feedback suggests that we were successful with both groups. Employees are working collaboratively and productively, and feedback from many clients has been positive. We have already seen the first few instances where a Charles River or WIL client has placed a study at an alternate location within our larger framework. We expect to see this happen more often, as clients take advantage of our broader portfolio, and leverage our global network. Biotech companies were the primary driver of revenue growth in the second quarter. We commented when we announced our planned acquisition of WIL, that even if biotech funding from the capital markets was to slow, we believe that biotech companies had sufficient cash on hand to fund research for a minimum of three years, a point of view which has been supported by a number of analyst reports, the most recent of which was published last week. Cash positions are being reinforced by continued support from large pharma, as those companies increasingly rely on biotech for new molecules. We continue to expect that biotech companies will be a significant source of revenue growth for us, which is one of the advantages of WIL's exposure to small and midsize biotech. The scientific strength and breadth of our unique portfolio is leading to enhanced dialogue with a wide range of clients. As we make progress on our goal to maintain and enhance our position as the premier nonclinical CRO, we are becoming the go-to partner for an expanding number of clients who recognize our expertise, scale, and deep commitment to them. We have increasingly become part of the solution to more efficient and productive drug research, where the clients utilize Charles River to augment their internal expertise, or because they have no in-house infrastructure and choose to partner with the most experienced scientific CRO. Working collaboratively with us to design studies and interpret the results expands our client's bandwidth and capabilities, as they make critical go and no-go decisions, relative to their early development pipelines. Our critical importance to our clients increases as we expand our broad portfolio. Therefore, they increasingly rely on our expertise. We believe that the continued expansion of our portfolio and our scientific expertise, superb execution and our flexibility relative to decision making speed and relationship structures, are the basis for long-lasting relationships with our clients and our future growth. We are maintaining our intense focus on the initiatives that we view as critical to expanding the value we provide for clients. We are continuing to assess opportunities to broaden our early-stage portfolio with strategic acquisitions such as the recent acquisition of Blue Stream. We are partnering with Venture Capital funds to gain access to their portfolio companies, and, as in the case of BioMotiv, which we announced on April 13, to work with academic researchers in both the UK and the U.S. Our continuing investment in internal systems and technology is the basis for improved access to and analysis of information, which increases our decision-making capabilities and the availability of real-time data to our clients. And perhaps most important, we are creating an enhanced working environment, with greater opportunities for our employees. At the end of the day, our employees are the reason that we worked on more than 55% of the drugs approved by the FDA in 2014 and 2015. It is their commitment to Charles River and our clients that makes us the premier early-stage contract research organization, and enables us to achieve our long-term growth goals and enhance shareholder value. In conclusion, I would like to thank our employees for their exceptional work and commitment, and our shareholders for their support. Now I would like David to give you additional details on our second quarter results.
