Hello, and welcome to the LyondellBasell Teleconference. At the request of LyondellBasell, this conference is being recorded for instant replay purposes. [Operator Instructions]

I would now like to turn the call over to Mr. David Kinney, Head of Investor Relations. Sir, you may begin.

David Kinney

Thank you, operator, and welcome everyone to today's call. Before we begin the discussion, I would like to point out that a slide presentation accompanies the call and is available on our website at investors.lyondellbasell.com.

Today, we will be discussing our first quarter results, while making reference to some forward-looking statements and non-GAAP financial measures. We believe the forward-looking statements are based upon reasonable assumptions and the alternative measures are useful to investors. Nonetheless, the forward-looking statements are subject to significant risk and uncertainty. We encourage you to learn more about the factors that could lead our actual results to differ by reviewing the cautionary statements in the presentation slides and our regulatory filings, which are also available on our
