Hello everyone, I'm Pascal Soriot. Welcome to the first quarter results conference call and our webcast presentation for the investors and analyst. We are in London today, where we are also hosting the Annual General Meeting this afternoon. We have people on the phone and on the webcast. The presentation is available online for all of you to download. Please turn to Slide 2; this is the Safe Harbor statement so moving onto Slide 3. We plan today to spend about 30 minutes on the presentation and then leave 30 minutes for Q&A. In total, we have exactly one hour together and we need to end on time as another company has a conference call starting in one hour. If you want to ask questions from the phone, you can get in on the line already now by pressing star one, there is also an option to ask questions online after the webcast. And we need to stay on time, please limit questions to one per person. This is to make it fair to everyone on the call. Thank you for your collaboration, we start. As usual I'm joined by Marc Dunoyer, CFO. Mark Mallon, our EVP for Global Portfolio and Product Strategy, Global Medical Affairs and Corporate Affairs and Sean Bohen, our EVP for Global Medicines Development and our Chief Medical Officer. We also have online Jamie Freedman, Business Head for Oncology. Please turn to Slide 4, so this is agenda today and move to Slide 5. So before we get started on financials just a reminder that we made refinements in our results announcement this morning. Emphasizing actual growth rate alongside growth rate at constant exchange rate. On our conference call today, we'll be making comment on our financial performance at CER which is a non-GAAP measure. With the formalities behind me, I'll now kick off. So in summary, we had a good start to 2017. Total revenue declined in the quarter primarily reflecting the tail of the last of US exclusivity for Crestor. New AstraZeneca which we define as the three main priority areas and the established medicines in the emerging market grew by 6% in the first quarter. The emerging markets were really a highlight and they were up 9% and they're now the biggest sales region in AstraZeneca. Within this region, China continued to perform well and so regulatory approval and launch for Tagrisso and approval for Forxiga. Our respiratory business delivered stable performance despite the ongoing challenges in the US and Symbicort remained the global leader by volume market share. In diabetes, another competitive field Farxiga continued to grow in all market. Despite subdued US goals due to the affordability programs and managed-care access. Brilinta continued to excel. Tagrisso was expanded on its impressive launches in the US and Europe and in Japan and now we are also accessing the private market in China. The core earnings per share declined was limited to 4%, given the continued cost focus, but also due to the continued sales progression of the New AstraZeneca. Now we'll turn to Slide 6. Our pipeline delivered very strong results since the last result announcement. This is most transistor [ph] of highlights for a long time. Let me cover handful of news items. First of Tagrisso news included the conversion from accelerated to full approval in the US and the EU and the important approval in China, that follows the very accelerated regulatory review. In the meantime, we've also launched Tagrisso in China with very good start. Lynparza received the regulatory submission acceptance and Priority Review in the US for the 2nd line application in ovarian cancer as well as an Orphan Designation for the same cancer in Japan. As the first ever type inhibitor Lynparza met a Phase III primary endpoint in BRCA-mutated metastatic breast cancer. Forxiga received the approval in China and SGLT2 class including Forxiga showed encouraging CVD outcome data in the CVD-REAL world study. Diabetes, the new Bydureon autoinjector was accepted for US regulatory review. The disappointing news was that we received a complete response later for ZS-9 in the US. However there are more milestone that shown we speak to later on a good start to 2017, should bode well for the rest of the year. Please turn to Slide 17. So when we look at New AstraZeneca it was another strong quarter where product sales grew at by 6%. All CRP areas contributed and so did the established medicines in the emerging market. As we move forward, these areas will be the key growth drivers as we exit the major patent losses for Crestor in the US. By July this year comparisons will ease and we look forward to keeping you updated on our return to growth in product sale. This graph in the light gray shading shows you that we are reaching the end of the impact of this large patent expiry. Please turn to Slide 8. As we begin returning to growth, our focus is increasingly on commercial execution and we've already launched Bevespi and Qtern, this year. At the end of the year, we anticipate the launch of Benralizumab our first biologic severe uncontrolled asthma. In bladder cancer, Durvalumab, US PDUFA date remains this quarter. We're also encouraged by the positive Phase III data for Lynparza and Metastatic breast cancer. There is also more new pipeline news flow expected over the next few quarters with MYSTIC and FLAURA as two important highlight. With the opportunity in 1st line lung cancer shared between Tagrisso and our IO medicine. We have the chance to become a leader in the treatment of lung cancer and so far we remained very confident in the MYSTIC bar refinement. With this, I'll now hand over to Mark Mallon.
