Thank you, Steve. By now you should have had a chance to review our first quarter results. On today’s call I’ll discuss four key measures of our financial performance; cash flow, revenue growth, margin and liquidity. First, cash flow. Our cash flow trends remain excellent. Free cash flow for the trailing twelve months ended March 31, 2010 increased 17% to $777 million, compared to $663.9 million in 2009, net of transition payments to United Healthcare. We are also pleased with our strong cash collection efforts in the quarter, as evidenced by significant improvement in DSO. DSO at the end of March was 46 days, an improvement of six days year-over-year. Although DSO increased two days sequentially, this increase is typical from the fourth quarter to the first quarter. As a result of our success in cash collections, we reduced our bad debt rate by 25 basis points. Second, revenue growth. Revenue increased 3.3% year-over-year in the first quarter. During the quarter we achieved strong growth in revenue per requisition, which increased 6.4% year-over-year. The growth in revenue per requisition is attributable to mix shift, increases in test per requisition and rate increases. The revenue growth per requisition was also impacted by the Canadian exchange rate, Monogram and the lost government contracts, which together improved revenue per requisition by 3.5%. Total company volume decreased 3% year-over-year. Excluding Canada, volume decreased 3.3% year-over-year. Inclement weather had a significant impact on the first quarter, resulting in an estimated 1.3% reduction in our volumes. Also the termination of two large government contracts at the end of the second quarter of 2009 reduced volume by 2.4%. Excluding these items, domestic volume increased 0.4% in the quarter. Esoteric volume increased 5.3% in the quarter. We estimate that bad weather lowered revenue by $23 million, and EPS by $0.08 in the quarter. Third, margin. For the first quarter our adjusted operating income margin was 20.4%. This margin decreased 40 basis points year-over-year, due primarily to the impact of weather. Fourth, liquidity. We remain well capitalized. At the end of March we had cash of $172.2 million, and approximately $440 million available under our revolving line of credit. At the end of March, total debt was $1.3 billion, including $20 million drawn down on our revolving credit facility. During the first quarter we repurchased $105.7 million of stock, representing approximately 1.4 million shares. At the end of March, approximately $216.1 million of repurchased authorization remained under our previously approved share repurchase program. This morning we reaffirmed our 2010 financial guidance. We expect revenue growth of 2.5% to 4.5%. Adjusted EPS in the range of $5.35 to $5.55, excluding the impact of any share repurchase activity after March 31, 2010. Operating cash flow of approximately $870 million, excluding any transition payments made to United Health Care and capital expenditures of approximately $135 million. I will now turn the call over to Dave.
