Thank you. Good morning, and thank you for joining American Tower's Fourth Quarter 2011 and Full Year Earnings Conference Call. We have posted a presentation which we will refer to throughout our prepared remarks under the Investors tab of our website, www.americantower.com. Our agenda for this morning's call will be as follows: First, I will provide a brief overview of our fourth quarter and full year results. Then Tom Bartlett, our Executive Vice President, CFO and Treasurer, will review our financial and operational performance for the fourth quarter and full year 2011, as well as our outlook for 2012. Finally, Jim Taiclet, our Chairman, President and CEO, will provide closing remarks. After these comments, we'll open up the call for your questions. Before I begin, I would like to remind you that this call will contain forward-looking statements that involve a number of risks and uncertainties. Examples of these statements include those regarding our 2012 outlook and future operating performance, our pending acquisition and any other statements regarding matters that are not historical facts. You should be aware that certain factors may affect us in the future and could cause actual results to differ materially from those expressed in these forward-looking statements. Such factors include the risk factors set forth in this morning's press release, those set forth in our Form 10-Q for the quarter ended September 30, 2011 and in our other filings with the SEC. We urge you to consider these factors and remind you that we undertake no obligation to update the information contained in this call to reflect subsequent events or circumstances. And with that, please turn to Slide 4 of the presentation, which provides a summary of our fourth quarter and full year 2011 results. During the quarter, our rental and management business accounted for over 98% of our total revenues, which were generated from leasing income-producing real estate, primarily to investment grade corporate tenants. This revenue grew 19.5% to nearly $641 million from the fourth quarter of 2011. In addition, our adjusted EBITDA increased 17.3% to approximately $429 million. Operating income increased 21.8% to approximately $248 million and net income attributable to American Tower Corporation was approximately $201 million or $0.51 per basic and diluted common share. Please note that our tax provision for the quarter reflects the positive net impact of approximately $121 million due to the reversal of certain deferred tax assets and liabilities as a result of our REIT conversion. For the full year 2011, our rental and management business grew 23.2% to nearly $2.4 billion. Our adjusted EBITDA increased 18.4% to approximately $1.6 billion and operating income increased 17.3% to approximately $920 million. Finally, net income attributable to American Tower Corporation was approximately $393 million or $0.99 per basic and $0.98 per diluted common share. And with that, I'd like to turn the call over to Tom, who will discuss our results in more detail.
