Good morning, and welcome to the IDEXX Laboratories Fourth Quarter 2019 Earnings Conference Call. As a reminder, today's conference is being recorded. Participating in the call this morning are Jay Mazelsky, President and Chief Executive Officer; Brian McKeon, Chief Financial Officer; and John Ravis, Senior Director, Investor Relations. IDEXX would like to preface the discussion today with a caution regarding forward-looking statements. Listeners are reminded that our discussion during the call will include forward-looking statements that are subject to risks and uncertainties that could cause actual results to differ materially from those discussed today. Additional information regarding these risks and uncertainties is available under the forward-looking statements notice in our press release issued this morning as well as in our periodic filings with the Securities and Exchange Commission, which can be obtained from the SEC or by visiting the Investor Relations section of our website, idexx.com. During this call, we will be discussing certain financial measures not prepared in accordance with generally accepted accounting principles, or GAAP. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures is provided in our earnings release, which may also be found by visiting the Investor Relations section of our website. In reviewing our fourth quarter 2019 results, please note all references to growth, organic growth, constant currency growth and comparable constant currency growth refer to growth compared to the equivalent period in 2018, unless otherwise noted. Fourth quarter 2019 and full year 2019 comparable constant currency, operating expense growth, operating profit growth, operating margin growth and comparable constant currency EPS growth exclude the impact of the fourth quarter 2019 CEO transition charges. (Operator Instructions) I would now like to turn the call over to Brian McKeon.
