Segment Reporting [Abstract]

Segment Information

Segment Information

Our principal business is the operation, acquisition and development of rental real estate properties. We evaluate our business by product type and by geographic location. Each product type has different customers and economic characteristics as to rental rates and terms, cost per rentable square foot of buildings, the purposes for which customers use the space, the degree of maintenance and customer support required and customer dependency on different economic drivers, among others. The operating results by geographic grouping are also regularly reviewed by our chief operating decision maker for assessing performance and other purposes. There are no material inter-segment transactions.

Our accounting policies of the segments are the same as those used in our Consolidated Financial Statements. All operations are within the United States.

The following tables summarize the rental and other revenues and net operating income, the primary industry property-level performance metric used by our chief operating decision maker which is defined as rental and other revenues less rental property and other expenses, for each of our reportable segments:
