Lisa A. Hook
Thanks very much Dave, and thank you all for joining us this afternoon as we report our results for the fourth quarter and for the full year. I will provide some perspective on 2011, and then, Paul Lalljie, our Chief Financial Officer will walk you through our results in detail.2011 was the year of tremendous change for NeuStar, obviously starting with the new CEO. It was a year in which every process and every person in the company was affected by our transformation. It was also a year in which we told our shareholders exactly how we intended to drive shareholder value, and then we did it. And amidst a significant amount of change, the one reliable constant was NeuStar’s strong performance. In the fourth quarter, we once again delivered strong growth in revenue, earnings and cash flow. We did so even as we completed three major transactions, which included a share buyback on an accelerated basis, our first term loan and the acquisition of TARGUSinfo. Our performance in the fourth quarter was a reflection of how pivotal a year 2011 turned out to be, and how when it comes to NeuStar’s results, the more things changed, the more they stayed the same. Revenue was up 27% compared to the fourth quarter of 2010. NPAC service revenue increased 11%, and is expected to be under 15% of total revenue in 2012. The business segment, we now call information services, which is how we identify our successfully integrated TARGUSinfo unit contributed 15 percentage points of the revenue increase we saw during the quarter.
