[Operator Instructions] Our Investor Relations team will be more than happy to follow up offline for any subsequent questions.And now I'll hand over the call to our CEO, Angus Russell. Angus C. Russell Thanks, Eric. Hi, everyone. So turning to Page 5, let me start by just summarizing these results overall. So once again, had a very strong quarter, very strong growth coming from a balanced product portfolio. You can see a consistent performance here. Overall product sales up 24% to $1.1 billion in the quarter, and total revenues up 21%. We turn to the next slide, Slide 6. You can see the same consistent performance reflected in both the operating income and the diluted earnings per ADS. Operating income on a non-GAAP basis up 18% to $362 million, and non-GAAP diluted earnings per ADS up 20% to $1.48. I'll now turn to some of the business highlights in the Specialty Pharma and Regenerative Medicine businesses, starting on Slide 7. VYVANSE grew very strongly again in this quarter. U.S. prescriptions grew 23% over the same quarter last year. We're now running at something like 16.8% market share. That's a gain of 1.7% versus the same period last year.
