Again, just a quick reminder that statements made in this conference call which state the company's or management's intentions, beliefs, expectations or predictions for the future, are forward-looking statements. It's important to note that actual results could differ materially from those discussed in forward-looking statements. Important factors that could cause actual results to differ materially include, but are not limited to, deterioration of global economic conditions; declines in customer spending and in oil and natural gas prices that could adversely affect demand for the company's services and their associated effect on rate, utilization, margins and planned capital expenditures; excess availability of land drilling rigs and pressure pumping equipment, including, as a result of reactivation or construction, adverse industry conditions, adverse credit and equity market conditions; difficulty in integrating acquisitions; shortages of labor, equipment, supplies and material; supplier issues; weather; loss of key customers; liabilities from operations; government regulation and ability to retain management and field personnel.Additional information concerning factors that could cause actual results to differ materially from those in the forward-looking statements is contained from time to time in the company's SEC filings, which may be obtained by contacting the company or the SEC. These filings are also available through the company's website and through the SEC EDGAR system. The company undertakes no obligation to publicly update or revise any forward-looking statements. Statements made in this conference call include non-GAAP financial measures. The required reconciliations to GAAP financial measures are included on our website, www.patenergy.com, and in the company's press release issued prior to this conference call. And now, it's my pleasure to turn the call over to Mark Siegel for some opening remarks. Mark? Mark S. Siegel Thanks, Mike.
