Thank you, Daphne. Good morning, everyone, and welcome to the Westlake Chemical Corporation First Quarter 2021 Conference Call. I'm joined today by Albert Chao, our President and CEO; and Steve Bender, our Executive Vice President and Chief Financial Officer; and other members of our management team. The conference call agenda will begin with Albert, who will open with a few comments regarding Westlake's performance and a current perspective on the industry. Steve will then provide a more detailed look at our financial and operating results. Finally, Albert will add a few concluding comments, and we'll then open the call up to questions. During this call, we refer to ourselves as Westlake Chemical. Any reference to Westlake Partners is to our master limited partnership, Westlake Chemical Partners LP, and similar references to OpCo refer to our subsidiary, Westlake Chemical OpCo LP, which owns certain olefins facilities. Today, management is going to discuss certain topics that will contain forward-looking information that is based on management's beliefs as well as assumptions made by and information currently available to management. These forward-looking statements suggest predictions or expectations and thus are subject to risks or uncertainties. Actual results could differ materially based on many factors, including the cyclical nature of the industries in which we compete, availability, cost and volatility of raw materials, energy and utilities; governmental regulatory actions, changes in trade policy and political unrest; global economic conditions, including the impact of the coronavirus; industry operating rates; impacts of extreme weather events; the supply-demand balance for Westlake's products; competitive products and pricing pressures; access to capital markets; technological developments and other risk factors as discussed in our SEC filings.
