Thank you, Nick. I'll start by providing an update on the market trends we're seeing so far in April. On a geographic basis, we're seeing ongoing improvements in Asia Pacific, most notably in China where the virus first emerged. However, we continue to experience significant downturns in the U. S., Europe and Latin America, areas that remain in the throes of the crisis. I can share that we are seeing a slowdown in growth during the first several weeks of Q2, with total company organic growth through late April down in the mid-teens. We anticipate continued strong demand for respirators, which we expect to contribute approximately 150 basis points to company-wide Q2 growth. At the same time, we expect ongoing weakness in other end markets through Q2, including oral care, automotive, office supplies and general industrial. Due to this end market uncertainty, at this time, we are unable to adequately quantify the impacts to our business for the remainder of the year. Therefore, we are temporarily withdrawing our 2020 guidance, until we have better visibility of the duration and impact of the slowdown. At this time, we believe Q2 results will be especially challenged, given the trends we have seen so far in April, with revenue and EPS declines year-over-year. In lieu of guidance, starting in May, we will provide monthly updates on how our business is performing and we will continue to provide this until we are better able to forecast future performance. Please turn to slide 14. To wrap up, our strong fundamentals and position with customers across industries provides a firm foundation during this time of uncertainty. We may not know the exact shape of the recovery, but we are well prepared for a wide range of scenarios and are taking actions to prepare us to lead out of this slowdown. Before turning to Q&A, I'd like to once again thank all 3Mers for your tremendous work and for everything you're doing in this unprecedented moment. I'm very proud to represent 3M and our people around the world. Going forward, we'll continue to do all we can to protect our employees, protect our enterprise and help the world get through this crisis. That concludes our remarks and we'll now take your questions.
