Brittany Raiford --
Director of Investor Relations
Thank you, Andrea. Good morning, and welcome to Southwestern Energy's First Quarter 2021 Earnings Call. Joining me today are Bill Way, President and Chief Executive Officer; Clay Carrell, Chief Operating Officer; Michael Hancock, Interim Chief Financial Officer; and Jason Kurtz, Head of Marketing and Transportation. Before we get started, I'd like to point out that many of the comments we make during this call are forward-looking statements that involve risks and uncertainties affecting outcomes. Many of these are beyond our control and are discussed in more detail in the risk factors in the Forward-Looking Statements section of our annual report and quarterly filings with the Securities and Exchange Commission. Although we believe the expectations expressed are based on reasonable assumptions. They are not guarantees of future performance, and actual results and developments may differ materially, and we are under no obligation to update them. We may also refer to some non-GAAP financial measures, which help facilitate comparisons across periods and with periods. For any non-GAAP measures we use, a reconciliation to the nearest corresponding GAAP measure can be found in our earnings release available on our website.
