Piedmont Office Realty Trust 8K Regulation FD Disclosure | PDM 12 Jun 12

1 Piedmont Office Realty Trust, Inc. (“Piedmont” or the “Company”) (NYSE: PDM) is a fully-integrated and self-managed real estate investment trust (“REIT”) specializing in the acquisition, ownership, management, development and disposition of primarily high-quality Class A office buildings located predominately in large U.S. office markets and leased principally to high-credit-quality tenants. Since its first acquisition in 1998, the Company has acquired $5.9 billion of office and industrial properties (inclusive of joint ventures). Rated as an investment-grade company by Standard & Poor’s and Moody’s, Piedmont has maintained a low-leverage strategy while acquiring its properties. Approximately 82% of our Annualized Lease Revenue ("ALR") is derived from our office properties located within the ten largest U.S. office markets, including Chicago, Washington, D.C., the New York metropolitan area, Boston and greater Los Angeles.
