Thank you, all, once again for joining us on SiriusXM's earnings call to discuss our fourth quarter and full year 2011 results, and more importantly, our expectations for the future. We are very pleased to report our 2011 results met or exceeded the guidance we gave you at the beginning of the year, and I'm even more excited about our prospects for accelerating revenue and adjusted EBITDA growth in 2012. We expect to deliver a very good year across the board in 2012. In 2011, we delivered the best year of subscriber growth since the merger of Sirius and XM by adding 1.7 million net new subscribers. Revenue reached a record of over $3 billion. Adjusted EBITDA climbed 17% to a record $731 million, beating our guidance of $715 million. Free cash flow essentially doubled to a record $416 million, beating our forecast of $400 million. These statistics paint a picture of remarkable growth and record achievements in 2011, and had we not been constrained on the revenue side by our agreement with the FCC and other litigation, our numbers would have been even stronger. Those handcuffs are now off for 2012 and beyond. For 2012, we are very optimistic about our ability to grow subscribers and at this time, we expect 1.3 million net additions this year, which should put our subscriber base at another all-time record high of 23.2 million by the end of the year. The consensus for auto sales in 2012 is approximately $13.7 million, which represents the highest number since 2007, which was before the merger of Sirius and XM. The fact that U.S. light vehicle sales should be up by 8% provides a solid foundation for subscriber growth this year. In addition to new car sales we expect this year, we will see a bigger contribution from the reactivation of radios in used cars. Our net subscriber addition guidance is tempered by our sense of conservatism around the price increase we implemented January 1, 2012. Since the time of the Sirius and XM merger, we have been conservative in all of our subscriber growth forecast. I believe this is a prudent cost and we will continue that practice. We will update our guidance, if appropriate, as the year progresses. On January 1, the price restrictions came off and we raised the base price of our service by just under 12% to $14.49 per month. This was the first increase in the core price in the history of Sirius service, and only the second time ever on the XM platform. I'm pleased to report that initial indications about consumer reaction to the price increase are meeting our expectations. While no one likes to pay higher prices and we certainly don't like to charge more as we're competing against free services like AM, FM radio and IP radio, we are not seeing any major problems yet from the increase. It is still early, so we need to be conservative in our outlook. We will also continue to provide the best customer service possible. So when there are complaints, we are able to minimize churn. Because of the price increase and our conservative outlook, we expect churn to be up modestly this year, probably in the 2.1% range. Without the price increase, we would be providing self-pay churn guidance consistent with past years of 1.9%. And we continue to expect a conversion rate in the 44% to 46% range, depending upon mix. The price increase will benefit our revenue performance in 2012 and 2013 as it rolls out and flows through the subscriber base. We are projecting that revenue will grow by almost 10% to a record $3.3 billion this year, and we expect further revenue growth in 2013 from more subscribers and a full year's effect on our price increase. In addition to our subscriber revenue focus, we expect advertising revenue will outperform the percentage increase in total revenue as we attract more blue chip advertisers. Advertising represents a very small but profitable segment of our revenue. Because our revenue growth will exceed expense growth, our adjusted EBITDA should grow by 20% this year to approximately $875 million, also a new record high and the best operating margin in our history. We still believe that we have plenty of room for margin growth over the next several years, and that a 40% long-term adjusted EBITDA target is a reasonable goal. Keep in mind that we have a significant improvement in a material OEM contract in late 2013 that will benefit EBITDA and margins in 2013 and 2014. The last but not the least piece of our guidance is for free cash flow to grow by nearly 70% to a record $700 million this year. All of our 2012 financial metrics are anticipated to be very strong, even if we only deliver the net adds we are currently forecasting. Used car sales continue to gain momentum for us. To augment our programs for buyers of certified preowned vehicles, we are also rolling out trials to all buyers of satellite radio-equipped cars at increasing numbers of franchise dealerships. In 2011, we announced programs to enroll Chevy, Buick, GMC, Cadillac and Nissan dealers nationwide in a new program where we are providing all purchasers of used vehicles of any brand, not just certified preowned, with a complimentary 3-month trial of SiriusXM. This year, we announced that we are expanding this program to Chrysler dealers, as well as launching a similar program at the country's largest independent auto retailer, AutoNation. Currently, across the different brands, we have enrolled over 4,000 dealers nationwide in our non-certified preowned used car program. More OEM brands, franchise dealers will be announced later this year. It's a fantastic benefit to the used car sales process and it's also a great way for consumers to trial satellite radio in newly acquired used cars. We expect that the previously owned market will be a major growth opportunity in the coming years. In 2012, we will introduce a variety of new services to broaden the availability of our suite of premium content. One major way we will do this is through an on-demand service across our IP platforms such as the web, smartphones and other connected devices. This On Demand platform will enable subscribers to access a continuously updated library of some of our best content and listen on their own schedules, not just those of our programmers. We think the service will drive demand for our Internet add-on option and all-access tier which will improve ARPU and only make our service more -- and have it be a must have ownership for our consumers. None of our IP-based competitors will have anything remotely approaching the depth and breadth of our non-music online offerings. Later this year, we will also debut personalized radio on the same IP platforms. This will let people tailor music to their own preferences. We believe on-demand and personalization will add to increased customer satisfaction and improved churn and conversion. We look forward to offering this to subscribers this year. Both of these new services, on-demand and personalization, will be available at no additional charge to subscribers who upgrade to our Internet add-on, making this option all the more desirable. Similarly, our additional 2.0 channels, including the suite of Hispanic channels, will be available at no extra charge to subscribers who have a 2.0-capable satellite radio. Adding this functionality on the Internet and increasing our content line-up on the satellites are 2 very visible ways we are adding value to our service and keeping the service attractive to consumers in the face of more competition. We are also investing in subscriber-exclusive events, such as our very special upcoming March 9 concert with Bruce Springsteen and the E Street Band at the Apollo Theater here in New York. This concert celebrates Satellite Radio's 10th anniversary. The only way to see this concert will be via a lottery exclusively for our subscribers, and the only way to hear the concert will be on SiriusXM's exclusive Bruce Springsteen's E Street Radio channel. This kind of event is not only a great source of exclusive content for us, but it also helps us generate a tremendous amount of media attention and buzz about the consumer benefit of being a SiriusXM subscriber. Remember, although we are the only satellite radio company, we do face numerous competitors and this competition is increasing in the IP world as there is no real barrier to entry. In 2011, SiriusXM was factory-installed in about 2/3 of all cars sold in America, while AM and FM radio was ubiquitous. Today, we are not seeing IP as a game changer. IP easy-to-use connectivity in cars is still very modest, but will become more common place over the coming years. Terrestrial radio is still our biggest competitor by far, and we know very well how to compete with it. What also gives us comfort as we face these challenges is that we continue to have a prime place in the car's dashboard and that we have the economic model to support this position and deliver valuable, often exclusive content that consumers love. Unique proprietary distribution of our satellite service through OEMs remains important, and our relationships with all of our OEMs are very strong. They are embracing 2.0 technology and those rollouts will begin this year and roll out to more OEMs over the coming years. OEMs love the entertainment we offer their car buyers and our relationships are stronger than ever. Demonstrating this is the penetration into OEM models and trends continue in 2011. SiriusXM's satellite radio are now factory-installed in 67% of all new vehicles, up from 62% in 2010. Our subscription-based business model is superior to that of terrestrial radio and IP radio, but this model clearly benefits our investors. For the full year of 2011, SiriusXM generated approximately $139 of revenue per year, per subscriber. The largest terrestrial radio company received only approximately 10% of what we did or about $13 of revenue for each of its listeners per year. The difference is even more extreme when you compare the largest IP competitors' revenue with the number of regular users that they have, and you see that they will generate less than $6 of revenue per year for each active user. This demonstrates the difficulty of generating advertising revenue for mobile users on their smartphones. Business models matter for investors and SiriusXM has a great one. Another interesting statistic to look at is revenue per employee. At SiriusXM, we generate approximately $2 million per employee per year as compared to IP radio, which is less than half that. Interestingly, terrestrial radio generates about $300,000 per employee compared to our $2 million. Our business model will be even more important to investors as revenue growth accelerates. Because of our powerful, scalable business model, we have the ability to offer premium content and also commercial free music as an option that is simply not available to advertising-based companies that wish to make a profit. We have always said that great content is critical and never is that more true than today. We are also notable for being the only company in the premium content business, where programming costs are actually dropping. In 2008, we spent $447 million on programming costs or 18.3% of our adjusted revenue. In 3 years, we have reduced our programming costs by 27% to $324 million or just 10.7% of adjusted revenue. In 2012, we will spend less on programming than we did in 2011, both in absolute dollars and as a percentage of revenue. Compare that to other video premium content providers, and you will find that their content costs are going up often even faster than their revenues. We're accomplishing this cost reduction while the quality and the quantity of our programming is increasing. While we are proud of our cost savings in this area, among others in our company, you should know that we have the means and the ability to increase investments in content should the right content become available. We will never stop evolving and enhancing the content we offer our subscribers. In closing, I want to remind investors that the company is laser-like focused on growing subscribers and growing free cash flow. Free cash flow is a financial metric that I believe can create value for shareholders. David will talk more about the financials and balance sheet. But let me just say that I'm very pleased about our prospects for growing free cash flow rapidly over the next few years. Not only do we expect continued expansion in our revenue and adjusted EBITDA, but we also expect to deliver most of this adjusted EBITDA as free cash flow. Some companies generate lots of EBITDA, but a much smaller amount of free cash flow. But in our case, our EBITDA to free cash flow conversion will continue to benefit from 4 positive factors. First, subscribers prepay for our service, which generates cash as new subscribers come on board and current subscribers renew. Second, our interest expense should fall as we refinance and deleverage, already our debt trade levels that imply a far lower borrowing cost for future issuance than what we are currently paying. Next, capital expenditures will fall significantly as we finish the deployment of our second generation of satellites in the first half of this year. We don't expect to start spending significantly on new satellites for another 5 years. And finally, our net operating loss carryforwards total some $7.8 billion. It should allow us to pay minimal cash taxes for many years to come. Our ending cash balance in 2012 should be about $1.5 billion or about $1.2 billion if you assume we call the 9 3/4% notes this September. And our gross leverage will have fallen to under 3.2x. There is an opportunity for the Board of Directors to consider a return of capital to shareholders beginning later this year. The board has not taken up this topic, so obviously no decision has been made as yet. Despite all the competition, our company has more paying subs today than ever before in its history. We have plans to grow this record level of subscribers, accelerate our revenue growth and dramatically grow our free cash flow in 2012 and beyond. If we keep offering great content and making it easy for consumers to access, I have no doubt that Sirius and XM will continue to prosper in the coming years. We are starting this year very strong. New car sales in January were up 11%. We will end 2012 with a record number of subscribers, record revenue, record adjusted EBITDA, highest margin ever and record free cash flow. The company is well positioned to deliver subscriber growth and free cash flow for many years to come. With that, I'll turn it over to David for some additional remarks.
