Flores, PXP's chairman, president, and CEO. "His hard work and intelligent leadership has been very much appreciated by everyone at PXP. I wish Steve well in his new endeavors as he will always be a significant part of the PXP family."

As CFO of PXP, Thorington was responsible for various aspects of the acquisitions of 3TEC Energy in 2003 and Nuevo Energy in 2004, including several debt restructurings and significant integration activities. Since PXP's inception as a public company, the equity market value has grown from approximately $200 million to approximately $3 billion and the return to shareholders has been approximately 300 percent.
