Ladies and gentleman thank you, for standing by. Welcome to Armstrong World Industries Third Quarter 2007 Earnings Conference Call. At this time all participants are in a listen-only mode. Later we will conduct a question-and-answer session. Instructions will be given at that time. As a reminder this conference is being recorded. I would now like to turn the conference over to our host Ms. Beth Riley, Director of Investor Relations, please go ahead.
