We have a lot of great things to talk about today. So I'd like to now turn the call over to Jose.Jose Ramon Mas Thank you, Marc. Good morning, and welcome to MasTec's 2012 Second Quarter Call. Today, I will be reviewing our second quarter results, as well as providing my outlook for the markets we serve. Before we get started, I'd like to point out that during the second quarter, we finalized the sale of DirectStar, our DIRECTV retail sales business. DirectStar's results have now been classified as discontinued operations, and its revenues has been eliminated from our financial statements. Thus, my comments, as it relate to revenue, exclude revenues generated by DirectStar in both 2011 and 2012. Now some first quarter -- some second quarter highlights. Revenue for the quarter was $992 million, a 38% increase over the prior year's second quarter. EBITDA was $81 million, an increase of 14% over last year. Earnings per share was $0.37, an increase of 19% over last year's adjusted earnings per share, and organic revenue growth was 32%.
