Cashman concluded by saying, "As we enter 2008, we are very encouraged by the positive adoption levels we are experiencing and believe we have a very strong foundation for continued, long-term growth and financial success. While we are increasing our outlook for the year, we are also cognizant of the uncertainties relative to the current volatility in the capital markets, as well as concerns about economic slowdowns in certain major geographies. We believe we are well positioned to invest in and capitalize on the global market opportunities for growth and to leverage our extensive customer base, strategic vision, technology leadership, and solid business model to drive continued technological and operational excellence."
