Greetings and welcome to the Edwards Lifesciences Corporation Fourth Quarter 2011 Earnings Conference Call. [Operator Instructions] As a reminder, this conference is being recorded. It is now my pleasure to introduce your host, David Erickson, Vice President of Investor Relations. Thank you. Mr. Erickson, you may begin. David Erickson;Vice President of Investor Relations: Welcome, and thank for joining us today. Just after the close of regular trading, we released our fourth quarter 2011 financial results. During today's call, we'll discuss the results included in the press release and accompanying financial schedules and then use the remaining time for Q&A. Our presenters on today's call are Mike Mussallem, Chairman and CEO; and Tom Abate, CFO. Before I turn the call over to Mike, I'd like to remind you that during today's call, we will be making forward-looking statements that are based on estimates, assumptions and projections. These statements include, but aren't limited to, our expectations regarding sales and sales growth, gross profit margin, net income growth, earnings per share, SG&A, R&D, tax rates and free cash flow, diluted shares outstanding, foreign currency impacts and other financial expectations, including our assumptions regarding the timing and extent of the additional U.S. approvals, launches and reimbursement for the SAPIEN transcatheter heart valve. These statements also include our current expectations for regulatory submissions and approvals related to a variety of new products and indications, as well as the timing, status and expected outcomes of new or currently ongoing clinical trials, the expected impact, ramp-up and benefits of new product introductions and potential impacts of economic conditions and competitive products. These statements speak only as of the date on which they are made, and we do not undertake any obligation to update them after today. Although we believe them to be reasonable, these statements involve risks and uncertainties that could cause actual results or experiences to differ materially from the forward-looking statements. Information concerning factors that could cause these differences may be found in our press release, our annual report on Form 10-K for the year ended December 31, 2010, and our other SEC filings, which are available on our website at edwards.com. Also, a quick reminder that when we use the terms underlying and excluding special items, we are referring to non-GAAP financial measures. Otherwise, we are referring to our GAAP results. Additional information about our use of non-GAAP measures is included in today's press release. Also note that we calculate operating leverage as gross profit minus SG&A and R&D expenses divided by net sales. Now I'll turn the call over to Mike Mussallem. Mike?
