With that, I will it over to Brendan to comment on our second quarter results.
Brendan CavanaghThank you, Mark. Good morning everyone. As you saw from our press release last night, our second financial and operational results were excellent. We exceeded the high end of our guidance across all of our most important financial metrics including leasing revenue Tower cash flow, adjusted EBITDA and AFFO. Total revenues were $229.1 million, up 34% of the year earlier period. Site leasing revenues for the second quarter were $203.6 million or a 35.6% increase over the second quarter of 2011. Our leasing revenue growth was driven by organic growth and portfolio growth, including the impact of the Mobilitie acquisition which closed on April 2nd. The vast majority of our site leasing revenue comes from the US and its territories, with approximately 5.7% of total leasing revenue coming from international operations. Site leasing segment operating profit was a $158.8 million or an increase of 34.5% over the second quarter of 2011. Site leasing contributed 97.5% of our total segment operating profit. Tower cash flow for the second quarter of 2012 was $152.3 million or a 28.4% increase over the year earlier period. Tower cash flow margin was 79.3% compared to 80.1% in the year earlier period. Margins were slightly impacted by the addition of the less mature Mobilitie portfolio and are expected to be similarly impacted by the TowerCo acquisition and then resume their growth thereafter.
