Barbara Tuckfield --

Thank you, and good morning, everyone. Before we get started, I would like to remind everyone to read the safe harbor statement on Page 2 of the presentation, including the reference to forward-looking statements. Our presentation also includes references to operating earnings, which is a non-GAAP financial measure. Please refer to the reconciliation of GAAP earnings to operating earnings provided in the appendix. With us this morning are Jerry Norcia, President and CEO; David Slater, President and CEO-Elect of DTM; and Dave Ruud, Senior Vice President and CFO.
