As a reminder to members of the press, you are in a listen-only mode on this call, but please feel free to contact us after today's call with any questions you may have.At this time, I would like to introduce our Chairman, President and CEO, Mike Long. Michael J. Long Thank you, Greer, and thanks to all of you for taking the time to join us today. We executed well in the first quarter, with sales and earnings per share in line with our expectations. Cash flow generation was a bright spot for the first quarter as we generated $250 million in cash flow from operations with contributions from both business segments. We continue to manage the company for long-term growth and continuous improvement, which enables us to outperform the market regardless of the market conditions we operate in. We've also maintained gross margins in what is still a very difficult macro environment. Our return on working capital and return on invested capital continue to be strong.
