Thank you. Mr. Lucia, you may begin your conference.
William C. Lucia - President and CEO: Thank you, Evelyn. Good morning everyone. It's a pleasure to have you join our fourth quarter and full year 2011 earnings call. I'm Bill Lucia, CEO of HMS Holdings. I'll be hosting the call along with Walter Hosp, our CFO.
Our fourth quarter revenue was $99.7 million, up 14.3% year-over-year. For the full year, revenue was up 20.1% over 2010 and GAAP EPS increased 17.1% over the full year to $0.55 per share. After adjusting for HDI related transaction items, GAAP EPS was up 27.7%, $0.60 per diluted common share. Our accomplishments this quarter and throughout 2011 proved once again the growing need for HMS's cost containment services across all of our markets. We are pleased to have made significant strategic progress and our multiyear growth plan, including the transformational acquisition of HealthDataInsights or HDI. We are also affirming our prior 2012 guidance of $520 million of revenue and $0.98 of adjusted EPS. To start off this morning, Walter will take you through our Q4 and full year financial results. Then, I will briefly provide an overview of the quarter and the year. Then, we will take your questions. Walter?
Walter D. Hosp - SVP and CFO: Thank you, Bill, and good morning, everyone. I will walk through our fourth quarter 2011 results first and then turn to the full year results. Revenues for the fourth quarter of 2011 increased 14.3% year-over-year to $99.7 million. This included $2.2 million of revenue from the acquisition of HDI from December 16th through the 31st which we will refer to as the HDI stub period. Excluding this HDI stub period, revenue for the quarter was $97.5 million, up 11.8% over the prior year and $1.3 million below the implied revenue guidance for the quarter.
