Thank you, Chris, and good morning, everyone. Thank you for joining us on our second quarter 2011 earnings call. As noted in last night's press release, we again delivered solid financial results, which Mark will discuss later in the call. We continue to strengthen our business and increase shareholder value. Our focus remains on leasing, development and providing our tenants with the utmost in customer service. The company's continued success would not be possible without the valued contribution made by everyone at DFT. I thank each of you for all your hard work and dedication.
First and foremost, our focus is leasing. So therefore, I would like to begin with a leasing update. Microsoft comprises approximately of 18% of the company's annualized net base rent as of June 30. We reached an agreement with Microsoft to extend a 9.6 megawatt lease for an additional 8 years. This lease was scheduled to begin to expire in 1.6 megawatt increments in 2012. The new lease begins to expire in 2020 and continuous through 2025. The renew represents over 40% of all current critical load they have with us. We are very pleased that they have decided to extend their relationship with us. Yahoo! comprises approximately of 19% of the company's annualized base rent as of June 30. Their recent lease expiration range from 2012 through 2019. Yahoo! informed us in late June 2011 that they will not renew one of their leases representing 3% of the company's consolidated annualized base rent as of June 30, 2011. This lease expiration represents approximately 19% of all current and critical load they have with us. This building is located in Western Virginia, a very fiber-rich area. We are actively marketing this space and are optimistic about its leasing prospects. This lease will expire on April 30, 2012. Yahoo!'s next lease is scheduled to expire in the third quarter of 2015.
