Segment Information

Segment Information

The Company operates its portfolio of properties primarily throughout the Mid-Atlantic, Southeastern, Midwestern and Southwestern United States. Additionally, the Company owns certain assets in the United Kingdom. The Company reviews the performance of the portfolio on a geographical basis. As such, the following are considered the Company’s reportable segments:

REGIONS	MARKETS
Northeast	Southeastern PA; Lehigh/Central PA; New Jersey; Maryland
Central	Minnesota; Chicago/Milwaukee; Houston; Arizona
South	Richmond/Hampton Roads; Carolinas; Jacksonville; Orlando; South Florida; Tampa
Metro	Philadelphia; Metro Washington, D.C.
United Kingdom	County of Kent; West Midlands

The Company evaluates the performance of its reportable segments based on net operating income. Net operating income includes operating revenue from external customers, real estate taxes, amortization of lease transaction costs and other operating expenses which relate directly to the management and operation of the assets within each reportable segment.

The Company's accounting policies for the segments are the same as those used in the Company's Consolidated Financial Statements. There are no material inter-segment transactions.
