Brandywine Realty Trust is a diversified office and industrial real estate investment trust. The company develops and operates commercial properties in the largely suburban areas of western and northern Pennsylvania, New Jersey, California, Virginia, and Texas. As of 2006, Brandywine operated a total of 28.2 million square feet across its 284 office and industrial properties. Properties are largely two to three story buildings, generating revenue per square foot around $24.
Until its diversifying acquisition of Prentiss Properties Trust in 2006, the company operated much more exclusively in the Pennsylvania and mid-Atlantic markets. This helps to limit geographic real estate risk, but also may dilute the company's scale in a particular region and present operational challenges inherent entering new and unfamiliar markets.(Read more at Wikinvest )
