...All right. Good morning, and welcome to the 41st Annual JPMorgan Healthcare Conference. I'm Eric Joseph, senior biotech analyst with the firm. And let me just say how thrilled I am to be back here in person with you all to host this conference the best week of the year. I'm looking forward to what I expect to be an exciting slate of presentations and I expect also constructive discussions over the course of the week. Our first presenting company is PTC Therapeutics, and presenting on behalf of the company is Chief Operating Officer, Matt Klein. Before I hand it over, I just want to say -- sorry, I just want to note that we're going to be doing Q&A after the presentation in the room here. There will be mic runners. So just raise your hand if you have a question. You can also submit questions via the digital conference book, and I can work them in where appropriate. So with that, Matt, thank you. Matthew B. Klein ...
