"As we have previously communicated, product upgrade cycles typically impact unit volumes in the short term as our retail partners transition the beds on their selling floors. Over the long term, such new product innovation is an important driver of our growth. This process is expected to last until the beginning of the fourth quarter domestically and is already complete in some of our international businesses that introduced major new lines in the first quarter of 2006."
