Jeff, thank you. Good morning and welcome to Patterson-UTI's conference call for the fourth quarter of 2008. I trust that by now all of you have had an opportunity to read our earnings release, which was issued earlier this morning prior to the opening of the market. Our plan this morning, is to take a few minutes to review the results of the three and twelve months ended December 31, 2008, and to indicate some of the financial highlights from the just completed quarter, which I hasten to add, was an excellent quarter in terms of financial results. I will then turn the call over to Doug Wall, Patterson-UTI's President and CEO, who will make some brief comments on the results of the individual operating [expenses] and current operations. After Doug's comments on the quarter, I will make a few comments on the market outlook, even though we have very little clarity at the moment. As always, we will be prepared to take your questions following these prepared remarks. To summarize, net income for the three month period totaled $79.5 million or $0.52 per share, compared to $85.1 million or $0.55 per share, for the three months ended December 31, 2007. Revenues for the quarter were $570 million compared to $521 million for the fourth quarter of 2007. For the 12 month period ended December 31, 2008, net income totaled $347 million or $2.24 per share, compared to net income of $439 million or $2.79 per share, for the 12 months of 2007. Revenues were $2.2 billion for the year ended December 31, 2008, compared to $2.1 billion for 2007. In summary, we had an excellent fourth quarter and an excellent 2008. As reflected in our press release, these reported results for 2008 include three unusual non-cash items; number one, write off of the goodwill in our fluids business of $10 million, number two, a charge of $10.4 million related to the retirement of 22 rigs from our drilling rig fleet, and third, an impairment charge of $2.4 million related to some of our E&P properties. On an after tax kick basis, these three items reduce our earnings by a total of $0.12 per share for the quarter. Capital expenditures for the quarter were $119 million and $449 million for the year. During the quarter, we repurchased 1.5 million shares of the company, at an average price of $10.64. The remaining authorization under our share repurchase program now stands at $113 million. I would like to now turn the call over to Doug, who will discuss our operations for the fourth quarter and for the current quarter.
