I will now turn it over to Rich.Richard Kogler Thanks, Frank. At the end of the quarter, we had approximately 522,000 accounts, of which over 506,000 were Small and the remainder were Large. We continued to see strong worldwide growth driven by the expanding portfolio services that complement our core regulated waste service. For our SQ customers, the growth drivers remain Steri-Safe and Clinical Service compliance programs. And for our LQ customers the growth drivers are Sharps Management and Pharma Waste services. Worldwide, we continue to use our strong free cash flow to fuel growth through acquisitions. In the quarter, we closed 8 transactions, 5 of which were domestic and 3 international. For 2012, we anticipate internal growth rates for SQ to be at -- in the range of 8% to 10%; LQ, 5% to 8%; international, 5% to 8%; and recall and returns revenues between $95 million and $115 million. We remain very excited about our future growth opportunity because 80% of our LQ and 70% of our SQ customers only use one of our current service offerings. As customers adopt our multiple services, this can more than double or triple their revenues. I want to close by thanking each member of our worldwide team for their strong performance and continued commitment to our customers and shareholders. And now I'll turn it over to Mark. Mark C. Miller Thanks, Rich. I'd now like to provide insight on our current outlook for 2012. Please keep in mind that these are forward-looking statements.
