Good afternoon ladies and gentlemen. Thank you for standing by. And welcome to the PTC 2018 First Quarter Conference Call. Today's call is being recorded. If you have any objections, you may disconnect at this time. During today's presentation, all parties will be in a listen-only mode. Following the presentation, the conference will be open for question and then closing remarks will follow. I would now like to turn the call over to Mr. Tim Fox, PTC's Senior Vice President of Investor Relations. Please go ahead.
