Hello, and welcome to the Celanese first quarter 2021 earnings conference call and webcast. At this time, all participants are in listen-only mode. A question and answer session will follow the formal presentation. As a reminder, this conference is being recorded. It's now my pleasure to turn the call over to Brandon Ayosh, Senior Director, Investor Relations. Brandon, please go ahead.

Thank you, Kevin. Welcome to the Celanese Corporation first quarter 2021 earnings conference call. My name is Brandon Ayosh, Senior Director of Investor Relations. With me today on the call are Lori Rykerk, Chairman of the Board and Chief Executive Officer, and Scott Richardson, Chief Financial Officer. Celanese Corporation distributed its first quarter earnings release via Business Wire and posted prepared comments about the quarter on our Investor Relations website yesterday afternoon. As a reminder, we will discuss non-GAAP financial measures today. You can find definitions of these measures as well as reconciliations to the comparable gap measures on our website. Today's presentation will also include forward-looking statements. Please review the cautionary language regarding forward-looking statements, which can be found at the end of the press release as well as prepared comments. Form 8K reports containing all of these materials have also been submitted to the SEC. Because we have published our prepared comments yesterday, we'll now open the line directly for your questions. Kevin, please go ahead and open the line.

Thank you, and I'll be conducting your question and answer session. If you'd like to be placed in the question queue, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you'd like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing star one. One moment, please, while we poll for questions. Our first question today is coming from John Roberts from UBS. Your line is now live.
