Thanks, April, and good morning, everyone. Welcome to our first quarter 2012 conference call. Speakers with me this morning are Roger Lindquist, our Chairman and CEO; Tom Keys our President and Chief Operating Officer; and Braxton Carter, our Vice Chairman and Chief Financial Officer. The format for today's call is as follows: First, Roger will provide an overview of our business; Tom will then provide an update on a number of operational results and initiatives; and finally, Braxton will review the financial highlights for the first quarter 2012 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 in our earnings release, which is available at www.metropcs.com under the Investor Relations section. Before I turn the call over to Roger, 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, projections, predictions 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, will 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 financial plans, our estimates of capital expenditures, our prospects for success, our strategies in our positioning in a highly competitive wireless industry. Furthermore, included in our forward-looking statements are statements regarding our competitive positioning and promotional strategies, our operational focus and objectives, the drivers of customer adoption of our services, the availability and pricing of 4G LTE handsets and RCS, the effects in demand for our services, anticipated benefits of 4G LTE, our marketing initiatives and their benefits, the reasons for reduced growth, the buildout of 4G LTE, statements regarding the impact of investment spectrum on capital expenditures and free cash flow, the manageability of our debt maturities, our position from a balance sheet perspective, capital expenditure guidance 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 a number of risks, many of which are beyond our control including, but not limited to, the risk factors described in our earnings release and our annual report on Form 10-K, quarterly reports on Form 10-Q, including our 10-Q for the period ended March 31, 2012, filed this morning, 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 the Investor Relations section located under the About Us tab on our website or directly from contacting the Investor Relations department. Among these, for example, are risks related to competition, availability of spectrum, our ability of our networks to meet customer demands, the availability of 4G LTE handsets and the economy. We encourage you to review these documents. We've also provided supplemental slides that are available for download and printing on our Investor Relations website. 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 2012 may not be reflective of results for any subsequent periods.
