Thank you, Rob. Welcome to the Celanese Corporation fourth quarter 2021 earnings conference call. My name is Brandon Ayosh, Vice President of Investor Relations, and with me today on the call are Lori Ryderkirk, Chairman of the Board and Chief Executive Officer, and Scott Richardson, Chief Financial Officer. Celanese Corporation distributed its fourth 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 the prepared comments. Form 8K reports containing all these materials have also been submitted to the SEC. Because we published our remarks yesterday, we'll go ahead and open the line for questions. Rob, please go ahead and open the line. Thank you.

At this time, we'll now be conducting a question and answer session. If you'd like to ask a question, please press star 1 on your telephone keypad, and a confirmation tone indicates that your line is in the question queue. You may press star 2 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 the star keys. So that we may address questions from as many participants as possible, we ask that you limit yourself to one question and one follow-up. One moment, please, while we poll for questions. Thank you. And our first question today comes from the line of John Roberts with UBS. Please receive your questions.
