Jerre SteadThank you, Andy, and good morning, everyone. Welcome to all of our investors and to our IHS colleagues, especially our new colleagues from Displaybank, CAPS Expert and IMS Research. There's much to share with you today, so let's get to it. I'll start with the quarterly financial highlights. Revenue was up 17% in the first quarter. Adjusted EBITDA increased by 20%, second highest EBITDA quarter in history. And notably our adjusted EBITDA margin was 30.2%. As these metrics suggest, we are indeed tracking to our full year guidance, which we are also increasing today. This reflects our continued view of strong performance this year. We have issued a short supplemental deck to further illustrate key elements of our revenue and profit delivery on a historical quarterly and annual basis. Scott Key, our President and Chief Operating Officer, and Richard Walker, our Executive VP and CFO, will provide more details shortly. My many thanks to my colleagues for their hard work, diligence and performance as we are investing at the highest levels in our history. We're deploying new systems, implementing new processes and putting in place the right teams and structures as the foundation to a very bright future.
