Good afternoon. Thank you for joining our call today. And I’m glad to be participating in my first call as part of the Neurocrine team. During the fourth quarter of 2017 INGREZZA continued to show strong month-over-month prescription resulting in $64.5 million in net product revenue, with approximately 9,100 scripts filled. This compares to the third quarter 2017 net product revenue, of $45.8 million with approximately 5,100 total prescriptions filled. Net product sales during the fourth quarter were above our expectations largely due to high script volume, which increased by approximately 80% over the previous period. But we also benefitted from the slower than anticipated transition from the higher price to the 40 mg capsules per day, to the one 80 mg capsules per day. Importantly, the transition from the two 40 mg capsules to one 80 mg capsule was largely complete as we exited the quarter. Total Company revenues for the fourth quarter were $94.5 million inclusive of a $30 million milestone payment received from AbbVie for the FDA's acceptance of the elagolix endometriosis NDA in the fourth quarter. For the year ended December 31, 2017 net product sales of INGREZZA were $116.6 million and total Company revenues were $161.6 million inclusive of $45 million of revenue recognized from our collaboration agreements with AbbVie and Mitsubishi Tanabe Pharma Corporation. Net income for the quarter was $6.9 million, or $0.07 per diluted share, compared to a net loss of $44.7 million, or $0.51 loss per share for the same period in 2016. The gain for the quarter was largely driven by the $30 million AbbVie milestone received and also net product – growing net product sales. For the year ended December 31, 2017 the Company reported a net loss of $142.5 million, or $1.62 loss per share, as compared to a net loss of $141.1 million, or $1.63 loss per share for 2016. Research and development expenses were $25.6 million during the fourth quarter of 2017, compared to $22.6 million during the fourth quarter of 2016. The increase in R&D expenses principally due to increase program activity in R&D. For the year ended December 31, 2017 R&D expenses were $121.8 million compared to $94.3 million for the same period in 2016. This increase is primarily due to a $30 million exclusive licensing payment to BIAL in the first quarter of 2017 which was expensed as in-process R&D. Sales, general and administrative expenses increased to $56.3 million for the fourth quarter of 2017, from $23.7 million for the fourth quarter of 2016. For the year ended December 31, 2017 SG&A expenses were $116.9 million, compared to $68.1 million for the same period in 2016. This increase in SG&A expense across both periods is primarily due to commercialization activities for INGREZZA, including the hiring of our sales force. Our cash, investments and receivables position as of December 31, 2017 was nearly $800 million positioning us well to execute our near term Company strategy. Now look ahead to 2018, we remain encouraged by the initial results of the INGREZZA launch and the positive, clinical feedback received by our customers. We are still early in our launch cycle and do not plan to provide formal net product sales guidance for INGREZZA at this time. Revenue milestones under the AbbVie agreement for 2018 are expected to be $40 million contingent on FDA approval of Elagolix Endometriosis in Q2. Regarding operating expenses for 2018, we expect ongoing operating expenses to be approximately $365 million to $395 million. Key investments will be directed toward: number one, our sales and marketing organization to maximize the potential of INGREZZA by enhancing disease state awareness. And number two, internal R&D to meaningfully advance our programs and Tourette's syndrome, opicapone for Parkinson's Disease, congenital adrenal hyperplasia and post marketing studies of INGREZZA for tardive dyskinesia. In addition to these programs we also intend to file one IND in 2018, which we will provide further insight to when the timing is right. We look forward to another year of tremendous commercial and clinical development progress. With that I will now and the call over to our Chief Commercial Officer, Eric Benevich who will provide a commercial update.
