Thank you, Scott. The company delivered record earnings in 2021. Looking ahead to 2022, we believe demand for our products will remain strong. But the company will continue to face, many of the same challenges that impacted our operations in 2021. In terms of segments, we are cautiously optimistic about the consumption of cleaning disinfection, and personal wash products within Surfactants. We believe volumes will not return to the pandemic peak lab of 2020 hope will grow versus 2021. We expect industrial and institutional cleaning volumes to increase, as economies open. Surfactant demand within the agricultural and oil field markets should continue to grow due to higher commodity prices and new Stepan technologies. The long-term prospects for our Polymer business remain attractive. We expect stronger demand linked to energy conservation efforts and more stringent building codes. Additionally, we believe that the new U.S. infrastructure bill should provide tailwinds for the installation industry. However, in January, we experienced production challenges in our Polymer unit at Millsdale and unfortunately, we had to declare force majeure. At Millsdale, we are producing polymers at reduced rates and we are using our global network including the inquired INVISTA, Wilmington, North Carolina site to deliver products to our customers and albeit at higher cost. We expect to resume full production in early March. We anticipate our Specialty Product business results will improve slightly year-over-year. Despite continued raw material sourcing issues and higher prices, as well as our higher first-quarter polymer supply chain cost, we believe underlying market demand across most segments remains strong and we are optimistic about delivering another good year. Finally, today we are announcing my retirement from Stepan Company effective April 25th, 2022. I'm extremely pleased that Scott will be our next CEO. No one is better suited to lead us into the future. Under his leadership, the business has diversified its market presence, delivered innovative, sustainable technologies, and completed multiple acquisitions which have contributed to record results. It has been an honor and privilege to serve as a third founding family CEO of Stepan Company. I am proud not only of the value of that we have created for our employees, customers, and you, our shareholders, but how we have delivered those results. I am grateful to the Stepan employees around the world whose unwavering commitment to our mission has allowed us to grow and will ensure our future success. This concludes our prepared remarks. At this time, we would like to turn the call over for questions. Scott, can you please review the instructions for the question portion of today's call.
