Thank you. Welcome to RIM's fiscal 2011 Year End and Fourth Quarter Results Call. With me on the call today are Jim Balsillie, Co-CEO; and Brian Bidulka, CFO. After I read the required cautionary note regarding forward-looking statements, Jim will provide a business and strategic update, Brian will then review the fourth quarter results and I will discuss our outlook for the first quarter of fiscal '12. We'll then open the call up for questions. I would like to note that this call is available to the general public via call-in number and webcast. A replay of the webcast will also be available on the rim.com website. We plan to wrap up the call before 6 p.m. Eastern Time this evening. Some of the statements we'll be making today constitute forward-looking statements within the meaning of the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian Securities Laws. These include statements about our expectations and estimates with respect to product shipments, revenue, gross margins, operating expenses, CapEx, depreciation and amortization, earnings, channel inventory and seasonality for Q1 and beyond; our expectations regarding RIM's near- and long-term tax rates; our product development and marketing initiatives and timing, including our expectations relating to the BlackBerry PlayBook and its QNX operating system; developments relating to our carrier partners and other statements regarding our plans and objectives. We will indicate forward-looking statements by using words such as expect, plan, anticipate, estimate, may, will, should, forecast, intend, believe, continue and similar expressions. All forward-looking statements reflect our current views with respect to future events and are subject to risks and uncertainties and assumptions we have made. Many factors could cause our actual results, performance or achievements to be materially different from those expressed or implied by our forward-looking statements, including risks relating to our intellectual property rights; our ability to enhance our current products and development products and services; risks related to competition; our reliance on carrier partners, third-party manufacturers, third-party network developers and suppliers, including potential risks to our supply of functional components caused by the recent earthquake in Japan; risks relating to network disruptions and other business interruptions; our ability to manage our production processes; risks associated with our international operations; security risks and risks related to encryption technology; our ability to manage growth; difficulties in forecasting financial results, particularly over longer periods given the rapid technological changes, evolving industry standards, intense competition and short product life cycles that characterize our industry and other factors set forth in the Risk Factors and MD&A section in RIM's filings with the SEC and Canadian Securities Regulators. We base our forward-looking statements on information currently available to us, and we do not assume any obligation to update them except as required by law. I will now turn the call over to Jim.
