Thank you, Allen, and good morning, everyone. I'm Keith Terreri. I'd like to welcome you to our first quarter 2011 conference call. The speakers with me this morning are Roger Linquist, our Chairman, President and Chief Executive Officer; Tom Keys, our Chief Operating Officer; and Braxton Carter, our Executive Vice President and Chief Financial Officer. The format for today's call is as follows: first, Tom will provide an update on a number of operational results and initiatives; then, Braxton will review the financial highlights of the first quarter of 2011; and then Roger will provide an overview of our business, followed by a question-and-answer session. During today's call, we will refer to certain non-GAAP financial measures. We have reconciled these historical non-GAAP measures to GAAP measures on our earnings release, which is available at www.metropcs.com under the Investor Relations tab. Before I turn the call over to Tom, I want to remind you that certain information that we will discuss in this conference call may constitute forward-looking statements within the meanings of federal securities laws. Forward-looking statements are any statements not of historical fact that involve risks, assumptions and uncertainties that may not occur or could cause actual results or the timing of events to materially differ from those made in the forward-looking statements. Words such as believes, anticipates, expects, intends, plans, should, could, would, view, estimates, projects and other similar expressions typically identify forward-looking statements. Forward-looking statements include, but are not limited to, statements we make regarding our future operational or financial plans, our prospects for success and our positioning in the highly competitive wireless industry. Furthermore, included in our forward-looking statements are statements regarding the effect of seasonality on our business, the value of our services, the outlook for growth and churn in future quarters, pricing, our subscriber mix, opportunities related to handsets' availability and pricing, our expected buildout of our 4G LTE network, it's worldwide growth, and the potential economies of scales to be obtained, our positioning from a balance sheet perspective and cost competitive position, our estimates of capital expenditures and other statements which are not historical. Management may make additional forward-looking statements in response to questions. Additionally, our forward-looking statements are subject to the risk factors described in our earnings release in our annual report on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, copies of which can be obtained free of charge from the SEC at www.sec.gov, or from our website or directly from contacting the Investor Relations Department. We encourage you to review these documents. We have also provided supplemental slides that are available for download and printing on our Investor Relations website. These slides may contain forward-looking statements. We may refer to these slides during our prepared remarks and in response to questions. I'd like to remind you that the results for the first quarter may not be reflective of results for the full year or any subsequent period. For anyone listening to a taped or webcast replay, or reviewing a written transcript of today's call, please note that all information presented is current and should be considered valid only as of May 3, 2011 regardless of the date reviewed, read or replayed.
