Thank you Eric and good afternoon everybody. This is a very important time at Theravance and we are making good progress towards our 2015 goals. In particular I'm very pleased with last week’s approval by the FDA of BREO for the treatment of patients 18 years and older in the U.S. with asthma which according to IMS represents approximately 92% of total U.S. LABA ICS prescriptions for asthma. This is a significant catalyst for Theravance that provides an important new treatment option for patients and physicians dealing with a serious disease that substantially expands the market opportunity for BREO in the U.S. and it sets Theravance up for a successful 2015. In building Theravance as a standalone company, one of our primary objectives was to create an efficient low cost company with a short path to profitability. I'm pleased to report that in the first quarter of 2015 we have made further progress towards this goal by reducing operating expenses and expanding operating margin versus Q4 last year. Our second important goal of the spin was to return capital to shareholders. As part of this initiative we paid a cash dividend of $0.25 per share on March 31, 2015 and today declared another dividend of $0.25 payable on June 30 to stockholders of record as of the close of businesses on June 12, 2015. Turning now to our programs RELVAR/BREO is our lead respiratory program partnered with GSK for the treatment of patients with chronic obstructive pulmonary disease or COPD and asthma, it is a combination inhaled respiratory medicine consisting of vilanterol, a long-acting beta2 agonist or LABA, and fluticasone furoate, an inhaled corticosteroid, or ICS, both delivered in the ELLIPTA dry powder inhaler. As of March 31, 2015, this medicine has been approved in 58 countries and launched in 36. Total net sales for RELVAR/BREO during the first quarter of 2015 were approximately $60 million. Our second respiratory program with GSK, ANORO, is a combination dual bronchodilator medicine for the treatment of COPD consisting of the LABA vilanterol and the long-acting muscarinic antagonist, or LAMA umeclidinium. As of March 31, 2015, it has been approved in 50 countries and launched in 20. Total net sales for ANORO during the first quarter of 2015, was approximately $18 million. While we are still early in the launch cycle for both products, we're optimistic about the prospects for our portfolio. So far in 2015 we have continued to see further growth in volume and market share for both products. For example, according to IMS total U.S. prescription volumes increased by 35% for BREO and 46% for ANORO in Q1 2015 compared to Q4 2014. In the U.S. a number of positive events and changes are in process, first as we discussed on our last conference call the collaboration plan to grow product volume by making significant commercial investments in higher levels of couponing and gaining additional payer coverage with the cost of these initiatives being a wider growth to net spread. We believe these investments are paying off as total prescriptions for both products increased significantly during Q1 as discussed above. Second, new GSK management and commercial teams in the U.S. are now in place and the salesforce is being reorganized to create dedicated teams for BREO and for ANORO. As GSK mentioned during their call today, the asthma launch event in the U.S. will occur shortly and as part of a new launch for BREO in the U.S. We believe this new indication could provide a significant sales catalyst as asthma affects nearly 19 million adults in the U.S. We are supportive of these actions by GSK and believe they will have significant positive effect on the prospects to our portfolio. Outside the U.S. we continue to see volume growth as well. For example excluding the impact of Q4 stocking associated with the ending of Ryotan restrictions on BREO and currency fluctuations, net sales were up significantly in Q1. Additionally during their call earlier today, GSK forecast up to 16 new market launches with our products this year. As we have discussed before we can expect some lumpiness in reported net sales on a quarter-over-quarter basis as we are still early in the growth phase of our products and new country launches, normal wholesaler inventory fluctuations and currency movements may continue to influence our quarterly results. Looking forward, the next major 2015 catalyst for BREO is the SUMMIT study which evaluates the impact of BREO on all cause mortality in 16,000 patients with preexisting cardiovascular risk factors. We expect SUMMIT to readout in the second half of the year. If the results are positive this could be a significant differentiating feature compared to other LABA ICS products in the treatment of COPD and support the future use of BREO in this patient population. We remain optimistic in the long-term growth drivers for both products, these drivers include the recent approval by the FDA of the asthma indication, the potential for approval and launch of both products in additional countries, further optimization of the ongoing commercial activities especially in the U.S., the results from the SUMMIT mortality study with BREO expected in the second half of the year and results from the Salford Lung Study in 2016. Throughout the rest of the year, we will continue to work closely with our partner GSK as we pursue our goal of optimizing the growth and commercial success of both BREO and ANORO across the globe. I'll now turn the call over to Eric who will review our first quarter 2015 financial results. Eric.
