Good morning ladies and gentlemen and welcome to the PTC's fourth quarter and fiscal year 2007 results conference call. At this time all participants are in a listen-only mode. Later we will conduct a question and answer session and instructions will follow at that time. [Operator instructions]. As a reminder, ladies and gentlemen, this conference is been recorded. I would now like to introduce Meredith Mendola, PTC's Vice President of Corporate Communications. Please begin.
