Thank you, and good afternoon, everyone. Thank you for joining us, and welcome to eBay's earning release conference call for the fourth quarter and full year 2011. Joining me today on the call are John Donahoe, our President and Chief Executive Officer; and Bob Swan, our Chief Financial Officer. We're providing a slide presentation to accompany Bob's commentary during the call. All gross rates mentioned in John and Bob's prepared remarks represent year-over-year comparison, unless they clarify otherwise. The conference call is also being broadcast on the Internet, and both the presentation and call are available through the Investor Relations section of the website at investor.ebayinc.com. In addition, an archive of the webcast will be accessible for 90 days through the same link. Before we begin, I'd like to remind you that during the course of this conference call, we will discuss some non-GAAP measures in talking about our company's performance. You can find the reconciliation of those measures to the nearest comparable GAAP measures in the slide presentation accompanying this conference call. In addition, management will make forward-looking statements relating to our future performance that are based on our current expectations, forecasts and assumptions and involve risks and uncertainties. These statements include, but are not limited to, statements regarding expected financial results for the fourth quarter and full year 2012, our 3-year outlook and the future growth in the Payments, Marketplaces and GSI businesses. Our actual results may differ materially from those discussed in this call for a variety of reasons including, but not limited to: global economic events; changes in political, business and economic conditions, including any further downturn or crisis in Europe; foreign exchange rate fluctuations; our ability to integrate, manage and grow businesses recently acquired or that may be acquired in the future, including GSI; our increasing need to grow revenues from existing users, particularly in more established markets and increasingly competitive environment for our businesses; the complexity of managing an increasingly large enterprise with a broad range of businesses at different stages of maturity; our need to manage regulatory, tax, IP and litigation risks, including risks specific to PayPal, Bill Me Later and the financial industry; and our need to timely upgrade our technology and customer service infrastructure at reasonable costs while adding new products and features and maintaining site stability and performance. You can find more information about factors that could affect our operating results in our most recent annual report on our form 10-K and our subsequent quarterly reports on form 10-Q available at investor.ebayinc.com. You should not rely on any forward-looking statements. All information in this presentation is as of January 18, 2012, and we do not intend and undertake no duty to update this information. With that, let me turn the call over to John.
