Robert F. Friel - Chairman, President and CEO: Thanks, Dave. Good afternoon and thank you for joining us for the PerkinElmer, fourth quarter 2010 earnings call. We are pleased with our performance in the fourth quarter, delivering another solid quarter of both top and bottom line growth.
Organic revenue grew 9%, adjusted operating profit margins expanded 60 basis points and adjusted earnings per share grew 19%. In addition to exceeding our financial commitments, we continue to make great strides on strategic priorities.
Touching briefly on our end markets, both the Human and Environmental businesses performed well in the quarter.
In Human Health, organic revenue grew 9% with our diagnostic businesses growing mid-teens, led by medical imaging and maternal and newborn health. In the research market, we grew mid single-digits led by the academic market and strong growth in our cellular imaging offerings.
In Environmental Health, we experienced 10% organic growth, driven by strong demand related to new and more stringent regulations for environmental and food safety. Andy will provide additional color around our end markets and our financial results in more detail later on this call.
